             $69,000,000 of 6% Convertible Subordinated Notes due
                        October 15, 2003 (the "Notes")
                  (Interest payable April 15 and October 15)
                                     and
               An Indefinite Number of Shares of Common Stock,
             No Par Value, Issuable Upon Conversion of the Notes
                                  -----------


     This  Prospectus  ("PROSPECTUS")  relates  to the  Offering  for  resale of
$69,000,000  aggregate  principal  amount  of  the  outstanding  6%  Convertible
Subordinated Notes due October 15, 2003, of UroMed Corporation,  a Massachusetts
corporation (the "COMPANY"),  and the shares (the "CONVERSION SHARES") of common
stock,  no par value per share (the "COMMON  STOCK"),  of the Company  which are
issuable upon  conversion  of the Notes.  The Notes are subject to an Indenture,
dated as of October  15,  1996 and a First  Supplemental  Indenture  dated as of
September 9, 1997 (collectively, the "INDENTURE"), between the Company and State
Street  Bank and  Trust  Company,  as  Trustee  (the  "TRUSTEE").  The Notes and
Conversion  Shares may be offered from time to time by the holders  thereof (the
"SELLING  SECURITYHOLDERS").  See "Plan of Distribution." Information concerning
the  Selling  Securityholders  may change  from time to time and,  to the extent
required, will be set forth in Supplements to this Prospectus.


   The  aggregate  principal  amount of Notes that may be offered by the Selling
Securityholders  pursuant to this Prospectus is  $69,000,000.  As of the date of
this  Prospectus,  the  aggregate  principal  amount  of  Notes  outstanding  is
$69,000,000.  The  Notes  are  convertible  into  Common  Stock  initially  at a
conversion  rate of 75.2941  shares per  U.S.$1,000  principal  amount of Notes,
subject to adjustment upon the occurrence of certain  events,  at any time prior
to the close of business on the maturity  date,  unless  previously  redeemed or
repurchased. Interest on the Notes is payable on April 15 and October 15 of each
year, commencing on April 15, 1997, with payment in full of the principal amount
of the Notes due on October 15, 2003.

     On or after  October 15,  1999,  the Notes are  redeemable,  in whole or in
part,  at the option of the Company at the  redemption  prices set forth herein,
plus accrued  interest.  If less than all of the Notes are to be  redeemed,  the
particular Notes to be redeemed shall be selected not more than 60 days prior to
the  Redemption  Date (as defined in the  Indenture),  by the  Trustee  from the
outstanding  Notes not previously  called for redemption,  by such method as the
Trustee shall deem fair and  appropriate and which may provide for the selection
for redemption of portions (equal to $1,000 or any integral multiple thereof) of
the  principal  amount  of Notes  of a  denomination  larger  than  $1,000.  See
"Description of Notes -- Optional Redemption."

     The Notes are unsecured  obligations of the Company and are subordinated in
the right of payment to all  existing  and future  Senior  Debt (as such term is
hereinafter  defined  under  "Description  of  Notes --  Subordination")  of the
Company and are expressly  made  subordinate  and subject in right of payment to
the prior  payment  in full of all  Senior  Debt.  There is no  Senior  Debt (as
defined in the Indenture)  outstanding as of the date hereof.  In addition,  the
Notes will be effectively  subordinated in right of payment to all  indebtedness
and other liabilities that may be incurred by any subsidiary of the

<PAGE>

Company. The Company has no subsidiaries as of the date hereof.  The
Indenture will not restrict the incurrence of any indebtedness, including
Senior Debt, by the Company or any subsidiary thereof.


     All of the Notes were  initially  issued and sold to Goldman,  Sachs & Co.,
PaineWebber  Incorporated  and J.P. Morgan  Securities  Inc. (the  "PURCHASERS")
pursuant to an exemption from the  registration  requirements  of the Securities
Act of 1933,  as amended  (the  "SECURITIES  ACT"),  provided  by  Section  4(2)
thereof.  The Notes were sold  simultaneously  by the Purchasers in transactions
exempt from the  registration  requirements  of the Securities Act in the United
States  to  persons  reasonably  believed  by  the  Purchasers  to be  Qualified
Institutional  Buyers as  defined in Rule 144A under the  Securities  Act,  to a
limited number of  institutional  investors  that are  accredited  institutional
investors  within the  meaning of Rule  501(a)  under the  Securities  Act,  and
outside  the United  States to  non-U.S.  persons in  offshore  transactions  in
reliance on Regulation S under the Securities  Act. The Company has not and does
not intend to apply for listing of the Notes on any  securities  exchange or for
inclusion of the Notes on any automated quotation system.


     The  Selling  Securityholders,  who  include  one  of  the  Purchasers,  as
principals for their own account,  directly, through agents designated from time
to time, or through dealers or underwriters also to be designated,  may sell the
Notes and  Conversion  Shares from time to time on terms to be determined at the
time  of  sale.  Such  dealers  may  include  the   Purchasers.   See  "Plan  of
Distribution." The Selling  Securityholders  and any  broker-dealers,  agents or
underwriters   that  participate  with  the  Selling   Securityholders   in  the
distribution   of  the  Notes  or   Conversion   Shares  may  be  deemed  to  be
"underwriters"  within the meaning of the  Securities  Act, and any  commissions
received by them and any profit on the resale of the Notes or Conversion  Shares
purchased  by them may be deemed to be  underwriting  commissions  or  discounts
under  the   Securities   Act.  For   information   concerning   indemnification
arrangements between the Company and the Selling  Securityholders,  see "Plan of
Distribution."


     The Common Stock is traded on the Nasdaq  National  Market under the symbol
"URMD." On April 30, 1998,  the last  reported sale price of the Common Stock on
the Nasdaq National Market was U.S. $2.06 per share.


     The Company  will not receive  any of the  proceeds  from the resale of the
Notes or Conversion  Shares.  The Company has agreed to bear certain expenses in
connection  with the  registration  and sale of the Notes and Conversion  Shares
being offered by the Selling Securityholders.

                                   THE COMPANY


UroMed Corporation (the "Company") is a developer,  manufacturer and marketer of
male and female  healthcare  products.  The  Company has  acquired or  developed
technology  in three core areas:  prostate  cancer,  urinary  incontinence,  and
breast  cancer.  The Company  has a direct  hospital-based  business  line and a
urinary incontinence  consumer-oriented  product line. The direct hospital-based
business  line is  comprised  of its  CaverMap  Surgical  Aid,  intended  to aid
physicians  in preserving  vital nerves  during  prostate  cancer  surgery,  its
Iodine-125  radiation  seeds for prostate cancer  brachytherapy,  and its BEACON
Technology System, a minimally invasive  incontinence  surgical line. In an area
where  the  Company  has  decided  to seek  marketing  partners,  the  Company's
doctor-prescribed  ("office-based")  continuum of  continence  care product line
includes the Impress Softpatch, the INTROL Bladder Neck Support Prosthesis,  the
Reliance  Insert,  and the PelvicFlex  video.  In breast cancer  screening,  the
Company is developing its investigational BreastView, BreastExam and BreastCheck
electronic  palpation  technology in order to aid physicians and patients in the
important mission of finding  suspicious breast lumps earlier.  The Company also
continues  to  dedicate   significant   resources  to  the  development   and/or
acquisition  of  product  lines  that  fit  into its  strategic  platforms.  The
Company's executive offices are located at 64 A Street in Needham, Massachusetts
02194. Its telephone number is (781) 433-0033.

                                RISK FACTORS

     AN INVESTMENT IN THE NOTES AND CONVERSION  SHARES OFFERED HEREBY INVOLVES A
HIGH  DEGREE  OF RISK.  PROSPECTIVE  INVESTORS  SHOULD  CONSIDER  CAREFULLY  THE
FOLLOWING RISK FACTORS,  IN ADDITION TO THE OTHER INFORMATION  CONTAINED IN THIS
PROSPECTUS, BEFORE PURCHASING THE NOTES OR CONVERSION SHARES OFFERED HEREBY.

UNCERTAINTY OF MARKET ACCEPTANCE FOR THE COMPANY'S PRODUCTS

The BEACON  Technology  system,  the CaverMap  Surgical Aid and the BEBIG Iodine
I-125 seeds will be competing against existing  treatments and surgical products
in the urinary  incontinence  and prostate  cancer  markets,  respectively.  The
Impress  Softpatch and the INTROL  represent a new approach to managing  certain
types of female UI. There can be no assurance that any of the Company's products
will gain any significant degree of market acceptance. The Company believes that
recommendations  by physicians  will be essential for market  acceptance of both
the  Impress  Softpatch  and the  INTROL,  which are and will be  marketed  on a
prescription  basis and  potentially an  over-the-counter  basis for the Impress
Softpatch, and there can be no assurance that any such recommendations,  if such
recommendations  are ever made, will be followed.  In addition,  there can be no
assurance  that the Impress  Softpatch and the INTROL will be accepted by female
UI sufferers in the United  States or abroad.  The Impress  Softpatch and INTROL
are each  patient-managed  therapies and as such patients may at any time decide
to  discontinue  their  use.  Results  of the  clinical  trials  of the  Impress
Softpatch  indicated  that some patients  experienced  slight tissue  irritation
after use of that device and that 48% of the patients were unable to report that
they were completely dry when using the device. Although the safety and efficacy
of the  Impress  Softpatch  and INTROL  were each  deemed to be  sufficient  for
clearance  by the FDA,  there  can be no  assurance  that  either  product  will
continue to prove to be safe and  effective  over the  long-term and after wider
use.

DEPENDENCE ON FEW PRODUCTS

The Company  expects to derive a  substantial  part of its revenues for the next
several years from sales of the Impress Softpatch, the BEACON Technology system,
the CaverMap  Surgical Aid and BEBIG's Iodine I-125 seeds. The Company's failure
to  commercialize  successfully  all of these  products  would  have a  material
adverse  effect on the Company's  business,  financial  condition and results of
operations.  The  Company  does not expect that  commercialization  of other new
product  will be  feasible  without  a  substantial,  continuing  commitment  to
research and  development  for an extended period of time or acquisitions of new
properties,  or both. Also, the development of any new products may require that
such products  will be subject to clinical  trials and  regulatory  clearance or
approval  before  commercialization.  There can be no assurance as to whether or
when  commercialization  of other  products  might begin or as to the likelihood
that any  such  initiative  would be  successful.  See  "Business--Research  and
Development."

LIMITED MANUFACTURING CAPABILITY AND EXPERIENCE

The Company has limited experience in manufacturing commercial quantities of the
Impress Softpatch and has not manufactured  significant  quantities of any other
products.  The  Company  may not be  able  to  develop  sufficient  capacity  or
capability  to produce  the  quantities  of the  Impress  Softpatch  that may be
required to support its sales.

DEPENDENCE ON OTHERS FOR COMPONENTS AND RAW MATERIALS

Certain of the raw materials for the  manufacture  and assembly of the Company's
products are available  only from single sources and are  manufactured  by third
parties.  Interruptions  in supplies of raw  materials  may occur as a result of
business  risks  particular to such  suppliers or the failure of the Company and
any such supplier to agree on satisfactory  terms.  Such sources may also decide
for reasons beyond the control of the Company,  such as concerns about potential
medical product liability risk in general,  to cease supplying such materials or
components  for  use in  medical  devices  generally.  In the  event  of such an
interruption, alternative sources of raw materials or components may be limited.
The Company is currently a party to supply  agreements with only some of its key
suppliers and may not be able to obtain agreements with some of its suppliers of
raw  materials  or  components  if it so desires.  In the event that the Company
replaces  its  current  raw  materials  used in the  Reliance  Insert or Impress
Softpatch with alternative materials, such product, as modified, may require new
FDA and other regulatory  approvals,  and additional  clinical and other testing
may be required  in order to obtain  such  approvals.  Any  interruption  in the
supply  of raw  materials  currently  used  by  the  Company  or any  components
incorporated  in the  Reliance  Insert,  or the  usage  of any  alternative  raw
materials,  would  have a material  adverse  effect on the  Company's  business,
financial condition and results of operations.

LACK OF MARKETING AND SALES EXPERIENCE

Although  the FDA has  approved or cleared  the BEACON  Technology  System,  the
CaverMap  Surgical Aid, the Impress  Softpatch,  the INTROL Bladder Neck Support
Prosthesis  and the  Reliance  Insert for  marketing in the United  States,  the
Company has sold only limited amounts or no quantities for each. The Company has
developed  a direct  marketing  and sales  group in the  United  States  for its
products.  However,  there can be no  assurance  that the  Company  has built an
effective  sales  force,  will be able to  continue  to  attract  and  retain  a
qualified  marketing  and sales  group in the United  States,  or can  otherwise
design and implement an effective  marketing  and sales  strategy for the BEACON
surgical kits, the CaverMap  Surgical Aid, BEBIG Iodine I-125 seeds,the  Impress
Softpatch,  and  BreastCheck,  BreastExam and BreastView,  or any future product
developed by the Company.

LIMITED OPERATING HISTORY; HISTORY OF LOSSES; PROFITABILITY UNCERTAIN

The Company has experienced significant operating losses since inception and, as
of December 31, 1997, had an accumulated  deficit of $105.9  million,  including
$30.2 million  relating to the acquisition of the Impress  Softpatch  technology
and related expenses. In addition,  the development and commercialization by the
Company of its products and other new products, if any, will require substantial
product  development  expenditures  for the  foreseeable  future.  The Company's
future profitability is dependent upon its ability to successfully commercialize
these  products.  There  can be no  assurance  that the  Company  will  generate
sufficient  cash flow to pay interest  and  principal on the Notes or to achieve
continued  profitability.  The Company expects its operating  losses to increase
over the foreseeable  future and there can be no assurance that the Company will
be profitable in the future or that the Company's existing capital resources and
any funds provided by future operations will be sufficient to fund the Company's
needs, or that other sources of funding will be available.

LACK OF DISTRIBUTION EXPERIENCE

The Company has limited  experience in distributing units of its products to its
ultimate  consumers.  In Europe,  where nearly all of the sales of the Company's
products have been made to date, the Company relied on the distribution  systems
of third party distributors.

COMPETITION AND TECHNOLOGICAL ADVANCES

The prostate cancer treatment and incontinence  surgery and incontinence product
industries  are  highly  competitive.  The  Company's  ability to compete in the
urinary  incontinence  management field will depend primarily upon physician and
consumer   acceptance  of  the  Reliance  Insert  and  the  Impress   Softpatch,
consistency of product quality and delivery, price, technical capability and the
training of health care  professionals  and consumers.  Other factors within and
outside the Company's control will also affect its ability to compete, including
its  product  development  and  innovation  capabilities,  its ability to obtain
required  regulatory   clearances,   its  ability  to  protect  the  proprietary
technology   included  in  its  products,   its  manufacturing,   marketing  and
distribution  capabilities  and  its  ability  to  attract  and  retain  skilled
employees.  Certain of the  Company's  competitors  have  significantly  greater
financial,   technical,  research,  marketing,  sales,  distribution  and  other
resources.

RISKS RELATING TO FDA OVERSIGHT AND OTHER GOVERNMENT REGULATION

The facilities at which the Company  manufactures  its products,  are subject to
regulation  by the FDA and, in many  instances,  by  comparable  agencies in the
foreign  countries in which these  devices are  distributed  and sold.  Although
approval to market the Reliance Insert and clearance to market Impress Softpatch
in the United  States  has been  granted by the FDA,  the  process of  obtaining
regulatory approvals for the marketing and sale of any additional  products,  or
the  modification  of  existing  products,  by the  Company  could be costly and
time-consuming and there can be no assurance that such approvals will be granted
on a timely basis, if at all. The regulatory  process may delay the marketing of
new  products  for lengthy  periods,  impose  substantial  additional  costs and
furnish an  advantage  to  competitors  who have  greater  financial  resources.
Moreover,  regulatory  approvals for new or modified products,  if granted,  may
include  significant  limitations  on the indicated  uses for which a product is
marketed.   In  addition,   the  extent  of  potentially  adverse   governmental
regulations that might arise from future legislative, administrative or judicial
action cannot be determined. The final approval granted by the FDA for marketing
the Reliance  Insert in the United States was  conditioned  upon final  labeling
review,  which has been  completed,  and an  undertaking to complete a five-year
post-marketing  study covering 150 patients designed to determine (i) the degree
of urinary tract infection associated with use of the device, including type and
frequency of symptomatic  bacteriuria,  and (ii) the long-term  effect of use of
the device on urethral integrity. If the FDA were to believe that the Company is
not in compliance with applicable law and regulations, the FDA could take one or
more  of the  following  actions:  withdraw  previously  approved  applications;
require notification to users regarding newly found, unreasonable risks; request
the  repair,  refund  or  replacement  of  faulty  devices;  request  corrective
advertisements,  formal  recalls or temporary  marketing  suspension;  refuse to
review or clear  applications to market any of the Company's  future products in
the  United  States or to allow the  Company  to enter  into  government  supply
contracts;  or institute legal  proceedings to detain or seize products,  enjoin
future violations or assess criminal penalties against the Company, its officers
or employees.  Civil penalties for Food, Drug and Cosmetic Act violations may be
assessed by the FDA in lieu of or in addition to instituting  legal action.  Any
such action by the FDA could result in disruption  of the  Company's  operations
for an  indeterminate  period of time. The Company's  manufacturing  facility in
Needham,   Massachusetts,   the  operations  conducted  there,  and  any  future
manufacturing facilities developed or acquired by the Company and any operations
conducted  there are subject to  on-going  inspections  by the FDA.  The Company
registered the facility with the FDA in connection with its Pre-Market  Approval
application  for the  Reliance  Insert  and FDA  representatives  inspected  the
facility and operations prior to granting approval of such application. Although
the Company's facility passed inspection in connection with this approval,  as a
registered manufacturing facility subject to Good Manufacturing Practices,  this
facility is subject to future inspections no less frequently than once every two
years.  Any  revocation  of the  Company's  approval  for  marketing  either the
Reliance Insert or the Impress Softpatch, or any material product recall or loss
of certification of the Company's manufacturing facility,  would have a material
adverse  effect on the Company's  business,  financial  condition and results of
operations.  The Company is also subject to regulation under federal,  state and
local  regulations  regarding  maintenance  of a licensed  pharmacy,  work place
safety,   environmental   protection  and  hazardous  and  controlled  substance
controls,  among  others.  The Company  cannot  predict the extent of government
regulations or impact of new government  regulations which might have an adverse
effect on the production and marketing of the Company's products.

RISK OF INADEQUATE FUNDING; FUTURE CAPITAL FUNDING

The Company plans to continue to expend substantial funds on marketing, research
and product  development,  seeking out partnerships  that fit into its strategic
platforms and pursuit of regulatory approvals.

There can be no assurance that the Company's  existing capital resources and any
funds  generated  from  future  operations  will be  sufficient  to finance  any
required  investment or pay interest on and principal of the Notes or that other
sources of funding will be available.  In addition,  future sales of substantial
amounts of the Company's  securities in the public market could adversely affect
prevailing  market prices and could impair the Company's future ability to raise
capital through the sale of its securities.

UNCERTAINTY REGARDING PATENTS AND PROTECTION OF PROPRIETARY TECHNOLOGY

The  Company's  ability to compete  effectively  will  depend,  in part,  on its
ability to develop and maintain proprietary aspects of its technology. There can
be no  assurance  as to the  validity of the United  States  patents held by the
Company with respect to all of its  products,  or as to the degree of protection
offered by these patents.  There can be no assurance that the Company's  patents
will not be challenged,  invalidated or circumvented in the future. In addition,
there can be no  assurance  that  competitors,  many of which  have  substantial
resources and have made substantial investments in competing technologies,  will
not seek to apply for and obtain  patents that will prevent,  limit or interfere
with the Company's  ability to make, use and sell its products  either inside or
outside the United States.  The defense and prosecution of patent  litigation or
other legal or administrative  proceedings related to patents is both costly and
time-consuming,  even if the outcome is  favorable  to the  Company.  During the
pendency of any such  proceedings,  the Company may be  restrained,  enjoined or
otherwise  limited in its ability to make,  use or sell a product  incorporating
the patents or technology that are the subject of such claim, which would have a
material  adverse  effect on the  Company's  business,  financial  condition and
results of operations.  An adverse outcome in any such proceeding  could subject
the Company to significant liabilities to third parties, require disputed rights
to be licensed  from others or require  the  Company to cease  making,  using or
selling any products. There can be no assurance that any licenses required under
any patents or proprietary rights would be made available on terms acceptable to
the Company, if at all.

The Company also relies on unpatented proprietary technology and there can be no
assurance  that  others  may not  independently  develop  the  same  or  similar
technology or otherwise  obtain access to the Company's  unpatented  proprietary
technology.  In  addition,  the Company  cannot be certain  that others will not
independently  develop  substantially   equivalent  or  superseding  proprietary
technology,  or that an equivalent  product will not be marketed in  competition
with the Company's  products,  thereby  substantially  reducing the value of the
Company's proprietary rights. There can be no assurance that any confidentiality
agreements  between the Company and its  employees or  consultants  will provide
meaningful  protection  for the  Company's  trade  secrets,  know-how  or  other
proprietary  information in the event of any  unauthorized  use or disclosure of
such trade secrets,  know-how or other proprietary  information.  Finally, there
can be no assurance that the Company's  trademarks  chosen and  registered  will
provide meaningful protection.

PRODUCT LIABILITY RISK; LIMITED INSURANCE COVERAGE

The manufacture and sale of medical  products and the conduct of clinical trials
using new technology entail the risk of product  liability claims.  There can be
no assurance that the Company's  existing insurance coverage limits are adequate
to protect the Company from any  liabilities  which it might incur in connection
with the clinical  trials for any of its products or, the  commercialization  of
any of its  products.  Such  insurance is expensive and in the future may not be
available on acceptable  terms, if at all. A successful  product liability claim
or series of product  liability  claims brought against the Company in excess of
its insurance  coverage  would have a material  adverse  effect on the Company's
business,  financial  condition  and results of  operations.  In  addition,  any
claims,  even if not ultimately  successful,  could adversely  affect the market
acceptance of the Company's products.

DEPENDENCE ON KEY PERSONNEL

The  Company  is  dependent  upon a  number  of key  scientific  and  management
personnel (most of whom do not have employment  agreements providing for a fixed
term of  employment).  The loss of the  services of one or more key  individuals
would  have a  material  adverse  effect on the  Company's  business,  financial
condition and results of operations.  The Company's  success will also depend on
its  ability to  attract  and  retain  other  highly  qualified  scientific  and
management personnel. The Company faces competition for such personnel and there
can be no  assurance  that the  Company  will be able to attract or retain  such
personnel. See "Executive Officers of the Registrant."

UNCERTAINTY RELATING TO THIRD-PARTY REIMBURSEMENT

In the United States, third-party reimbursement is currently generally available
for  surgical  procedures  for  incontinence,   but  generally  unavailable  for
patient-managed  products  such as diapers  and pads.  As part of its  near-term
marketing plan in the United States, the Company does not believe it will obtain
government or private insurance reimbursement for its Reliance Insert or Impress
Softpatch and that the prospect of  substantial  third-party  reimbursement  for
either device in the United States may be difficult.  In Europe, the Company and
its  European   distributors  have  agreed  to  adopt  a  strategy  of  pursuing
reimbursement  for the use of the  Reliance  Insert in each of their  respective
territories   where  it  is   appropriate.   The   availability  of  third-party
reimbursement  for the Reliance Insert in Europe varies from country to country.
While the Company has received notice that full reimbursement for the use of the
Reliance Insert will be provided by the relevant  German,  Swedish and Norwegian
governmental authorities and by certain authorities covering much of Denmark and
Finland, it is unclear whether  reimbursement will be available for the Reliance
Insert in the remainder of Denmark or Finland, or whether  reimbursement will be
available  for the  Reliance  Insert in France,  The  Netherlands  or the United
Kingdom. It is also unclear whether or not such reimbursement approvals that the
Company has received  may at some point in the future be  reversed.  The Company
has not yet established a strategy with respect to seeking reimbursement for the
Impress Softpatch outside of the United States. If third-party  reimbursement is
unavailable in the relevant European country or in the United States,  consumers
will  have to pay for the  Reliance  Insert  or  Impress  Softpatch  themselves,
resulting in greater relative  out-of-pocket  cost of such therapies as compared
to  surgical  procedures  and other  management  options  for which  third-party
reimbursement   is  available.   Changes  in  the  availability  of  third-party
reimbursement for the Reliance Insert or Impress Softpatch,  for products of the
Company's  competitors or for surgical  procedures may affect the pricing of the
Company's products or the relative cost to the consumer. The Company is not able
to predict the effect that the  availability  or  unavailability  of third-party
reimbursement  for the  Reliance  Insert or  Impress  Softpatch  may have on the
commercialization  of  such  products  abroad  or  in  the  United  States.  See
"Business--Third-Party Reimbursement."

VOLATILITY OF MARKET PRICES

The market price of the Common Stock and Notes may be highly  volatile.  Factors
such as  quarter-to-quarter  variations in the Company's operations or financial
performance  and  announcements  of  technological  innovations or new products,
results of clinical trials or other  regulatory or  reimbursement  events by the
Company or its  competitors  or any of its or their  regulators  could cause the
market  price  of the  Common  Stock or Notes  to  fluctuate  significantly.  In
addition,  in recent years the stock  markets in general,  and the market prices
for medical  technology  companies in particular,  have experienced  significant
volatility,  which often may have been unrelated to the operating performance of
the affected companies. Such volatility may adversely affect the market price of
the Common Stock or Notes.

CERTAIN CHARTER AND BY-LAW PROVISIONS MAY AFFECT MARKET PRICES

The Company's  Restated  Articles of Organization and the Company's  Amended and
Restated  By-Laws contain  provisions that may have the effect of making it more
difficult  for  a  third  party  to  acquire  control  of,  or  of  discouraging
acquisition  bids for,  the  Company.  This could  limit the price that  certain
investors  might be willing  to pay in the future for shares of Common  Stock of
the Notes.

CERTAIN MASSACHUSETTS LAWS MAY AFFECT MARKET PRICES

Certain Massachusetts laws contain provisions that may have the effect of making
it more  difficult for a third party to acquire  control of, or of  discouraging
acquisition  bids for,  the  Company.  These laws  include  Chapter  110F of the
Massachusetts General Laws, which prohibits certain "business combinations" with
"interested  stockholders,"  and Chapter 110D,  entitled  "Regulation of Control
Share  Acquisitions."  These  provisions  could  limit  the price  that  certain
investors  might be willing  to pay in the future for shares of Common  Stock or
the Notes.

EFFECT OF ISSUANCE OF PREFERRED STOCK

Shares  of  preferred  stock  may  be  issued  in  the  future  without  further
stockholder approval and upon such terms and conditions, and having such rights,
privileges and preferences,  as the Board of Directors may determine. The rights
of the holders of Common  Stock or Notes  convertible  into Common Stock will be
subject to, and may be  adversely  affected by, the rights of the holders of any
preferred stock that may be issued in the future.  In addition,  the issuance of
preferred  stock could have the effect of making it more  difficult  for a third
party to  acquire  control  of, or of  discouraging  acquisition  bids for,  the
Company.  This could limit the price that certain  investors might be willing to
pay in the future for shares of Common Stock or the Notes.

CONCENTRATION OF OWNERSHIP

As of December 31, 1997,  directors  and  executive  officers of the Company and
their  affiliates  owned  approximately  19% of  the  outstanding  Common  Stock
(including  options to purchase Common Stock exercisable  within 60 days of such
date).  As a  result,  such  persons  have the  ability  to  assert  significant
influence  over the Company and the direction of its affairs and  business.  See
"Security Ownership of Certain Beneficial Owners and Management."

ABSENCE OF DIVIDENDS

The Company has not paid cash dividends and does not anticipate doing so for the
foreseeable future.

SHARES AVAILABLE FOR FUTURE SALE

The future sale of shares of the  Company's  Common  Stock could have an adverse
effect  on the  market  price of the  Common  Stock or the  Notes.  The  Company
currently has two effective registration  statements on file with the Securities
and Exchange  Commission  initially covering the resale of up to an aggregate of
8,519,538  shares of Common Stock held by certain  current  shareholders  of the
Company.  Of  these  8,519,538  shares,   6,184,512  shares  are  covered  by  a
registration  statement which was declared effective in October 1995 registering
shares  of  Common  Stock  held  by  approximately  73  holders.  These  shares,
representing  shares of Common Stock issued upon the conversion of the Company's
previously  outstanding  convertible  preferred  stock,  were  registered at the
request of the holders of such shares.  All of these shares,  with the exception
of 1,641,257  shares held by an affiliate of the Company,  may be sold currently
under Rule 144(k)  under the  Securities  Act without  regard to volume or other
limitations.  The remaining  2,335,026  shares,  which were issued to the former
shareholders  of Advanced  Surgical  Intervention,  Inc. in connection  with the
acquisition  of the Impress  Softpatch  technology in May 1996, are covered by a
registration  statement which was declared  effective in June 1996. These shares
are held by 273  holders,  with the largest  number of shares held by any single
holder thereunder being approximately  252,000 shares. The Company believes that
many of the shares covered by these  registration  statements  have been sold in
the open market  prior to the date  hereof.  All of the shares  covered by these
registration  statements are freely  tradeable in the open market without volume
limitations. As of December 31, 1997 the Company also has options outstanding to
purchase an aggregate of 1,722,538  shares of Common Stock and has an additional
404,249  shares of Common Stock  reserved  for issuance of options  which may be
granted and exercised under the Company's  existing  employee benefit plans. Any
shares of Common Stock issued upon the exercise of such  outstanding  options or
any options  granted in the future will be, upon issuance,  freely  tradeable on
the open market, subject in some cases to the volume limitations imposed by Rule
144 under the Securities  Act. As of December 31, 1997, the Company had reserved
5,195,391 shares of Common Stock for issuance upon conversion of the Notes.

RECENT EVENTS

The Company  restructured  its  operations  during the first  quarter of 1998 to
increase  its  emphasis on  hospital-based  sales  efforts  and to decrease  its
investment in the consumer-oriented  continence care business, which the Company
believes  is  best  approached  through  utilizing   marketing   partners.   The
restructuring involved the company-wide reduction of approximately 40 employees.
This initiative is designed to reduce operating costs while allowing the Company
to create a business model with a  significantly  lower  break-even  level.  The
Company will take a restructuring  charge of  approximately  $1.0 million in the
first quarter of 1998.

The Company has been increasing its emphasis on surgical  products,  such as the
CaverMap Surgical Aid and the BEACON Technology System, and other treatments for
prostate cancer such as the Iodine-I125  radiation  seeds, for which there exist
both large and focused  markets.  In the U.S.,  commercial  availability  of the
BEACON  Technology  System  began in the first  quarter  of 1998,  the  CaverMap
Surgical  Aid is expected to be  commercially  available  in  mid-1998,  and the
Iodine-I125  radiation seeds in early 1999. As the BreastCheck  technology moves
closer to market, the Company is assessing the optimal  commercialization  path,
either  through  direct  marketing  or via  partnerships  as well  as  financing
alternatives for this business.  Due to market  requirements and  opportunities,
the  Company  has  decided to seek one or more  marketing  partnerships  for its
consumer-oriented  continence care products:  the Impress Softpatch,  the INTROL
Bladder Neck Support Prosthesis, the Reliance Insert and the PelvicFlex Video.

During the first  quarter of 1998,  the Company  signed an agreement  with BEBIG
GmbH for the  exclusive  right to market  BEBIG's  Iodine-125  ("I125") seed for
prostate  brachytherapy  treatment in North and South America, and non-exclusive
rights   in   other   parts  of  the   world.   Prostate   brachytherapy   is  a
minimally-invasive  procedure in which small radiation sources, or "seeds",  are
implanted  into the  prostate  to  treat  localized  cancer.  The  procedure  is
frequently  performed  on an  out-patient  basis.  According to the terms of the
agreement, BEBIG will design and build an automated manufacturing line, based on
its proprietary  technology,  at its faciltiy in Berlin,  Germany. The agreement
calls for a total  commitment by the Company of  approximately  $1.75 million in
milestone payments to be made if BEBIG's  performance goals are met. The Company
intends  to launch  commercially  its Iodine  I-125  seeds for  prostate  cancer
brachytherapy in early 1999.

RATIO OF EARNINGS TO FIXED CHARGES

     As a result of the losses incurred by the Company since inception, earnings
have been  insufficient  to cover fixed charges.  The following table sets forth
the dollar amount by which  earnings did not cover fixed charges for the periods
indicated (amounts in thousands):

FISCAL YEAR ENDED DECEMBER 31


 1992     1993     1994     1995      1996      1997
$1,634   $3,708   $7,993   $9,712   $47,660   $34,633
 ----    ------   ------   ------   -------   -------

     For purposes of computing the ratio of earnings to fixed charges,  earnings
consist of the net loss plus fixed  charges.  Fixed charges  consist of interest
expense  and  one-third  of  the  rent  expense  from  operating  leases,  which
management believes is a reasonable approximation of an interest factor.

                               USE OF PROCEEDS

     The Notes and any Conversion Shares offered by the Selling  Securityholders
are not being sold by the Company, and the Company will not receive any proceeds
from the sale thereof.

                          SELLING SECURITYHOLDERS

     The Notes were  issued and sold by the  Company  to  Goldman,  Sachs & Co.,
PaineWebber  Incorporated,  and J.P. Morgan & Co. (the  "PURCHASERS") on October
15,  1996,  pursuant to a private  placement,  and were  acquired by the Selling
Securityholders  in  connection  with resale  transactions  with the  Purchasers
pursuant to Section  4(z) of the  Securities  Act,  Rule 144A,  Regulation  D or
Regulation S under the Securities Act or from other holders acquiring such Notes
from prior holders thereof.

     The Selling  Securityholders  may from time to time offer and sell pursuant
to this  Prospectus  any or all of the Notes and the Common  Stock  issued  upon
conversion of the Notes.  The term Selling  Securityholder  includes the holders
listed  below and the  beneficial  owners  of the  Notes and their  transferees,
pledges, donees or other successors.


     The  following  table sets  forth  information  with  respect to the record
holders  of  the  Notes  as of May  1,  1998.  It has  been  prepared  based  on
information   furnished   to  the  Company  by  or  on  behalf  of  the  Selling
Securityholders.  Each of Goldman,  Sachs & Co., PaineWebber  Incorporated,  and
J.P. Morgan & Co. maintain  ongoing  business  relations with the Company and in
connection  therewith  provides  investment  banking services to the Company for
which they receive  customary  fees.  None of the other Selling  Securityholders
has,  or within  the past three  years has had,  any  position,  office or other
material relationship with the Company.

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

     *  Less than 1.0%

     (1) Represents the number of Conversion  Shares into which the Notes listed
for such Selling  Securityholder in this table are convertible as of the date of
this Prospectus.  Prior to this Offering of the Notes and the Conversion Shares,
none of the Selling  Securityholders  owned any shares of Common  Stock.  Due to
rounding,  this column does not exactly total the aggregate number of Conversion
Shares initially issuable upon conversion of the Notes, which is 5,195,293.


     (2) Percentage of Common Stock  Outstanding is calculated  using the number
of shares outstanding on March 1, 1998 plus the number of Conversion Shares into
which  the  Notes  listed  for  such  Selling  Stockholder  in  this  table  are
convertible as of the date of this Prospectus.

     (3) Assumes that the unnamed  holders of Offered  Securities  or any future
transferees,  pledgees, donees, or successors of or from any such unnamed holder
do not  beneficially  own any Common Stock other than the Common Stock  issuable
upon conversion of the Notes at the initial conversion rate.

     The per share  conversion  price and,  therefore,  the number of Conversion
Shares  issuable upon  conversion  of the Notes is subject to  adjustment  under
certain  circumstances.  Accordingly,  the number of Conversion  Shares issuable
upon conversion of the Notes may increase or decrease. In addition,  the Selling
Securityholders  identified  above  may  have  sold,  transferred  or  otherwise
disposed  of all or a  portion  of their  Notes,  since  the date on which  they
provided the information  regarding their Notes, in transactions exempt from the
registration requirements of the Securities Act.

     Because the Selling Securityholders may, pursuant to this Prospectus, offer
all or some portion of the Notes or Conversion  Shares  issuable upon conversion
of the  Notes,  no  estimate  can be  given  as to the  amount  of the  Notes or
Conversion   Shares  of  Common   Stock  that  will  be  held  by  the   Selling
Securityholders upon termination of any such sales. In addition,  since the date
on which the Selling  Securityholders  provided the information  regarding their
holdings of Notes, they may have sold,  transferred or otherwise disposed of all
or a  portion  of  their  Notes in  transactions  exempt  from the  registration
requirements of the Securities Act.

                             PLAN OF DISTRIBUTION

     This  Prospectus  relates to the resale of  $69,000,000  of Notes issued on
October  15,  1996,  and the resale of the shares (the  "CONVERSION  SHARES") of
Common Stock issuable upon  conversion of Notes.  This Prospectus does not cover
the initial issuance of shares of Common Stock upon conversion of the Notes. The
Notes and  Conversion  Shares  may be offered  from time to time by the  Selling
Securityholders.

     The Selling  Securityholders,  acting as principals for their own accounts,
may sell all or a portion of the Notes or Conversion Shares from time to time on
any exchange on which such  securities  are listed on terms to be  determined at
the times of such sales. The Selling Securityholders may also make private sales
directly  or  through a broker or  brokers.  Alternatively,  any of the  Selling
Securityholders may from time to time offer the Notes or Conversion Shares which
may be  offered  hereby and  beneficially  owned by them  through  underwriters,
dealers or agents,  who may  receive  compensation  in the form of  underwriting
discounts,  commissions or concessions from the Selling  Securityholders and the
purchasers of the Notes or Conversion  Shares for whom they may act as agent. To
the  extent  required,  the  aggregate  principal  amount of Notes and number of
Conversion Shares to be sold hereby,  the names of the Selling  Securityholders,
the purchase  price,  the name of any such agent,  dealer or underwriter and any
applicable commissions,  discounts or other terms constituting compensation with
respect to a particular offer will be set forth in an accompanying Supplement to
this Prospectus.  The aggregate proceeds to the Selling Securityholders from the
sale of the  Notes or  Conversion  Shares  offered  by them  hereby  will be the
purchase price of such Notes or Conversion Shares of Common Stock less discounts
and  commissions,  if any. The Company will not receive any of the proceeds from
the resale of the Notes or Conversion Shares offered hereby.


     To the best  knowledge  of the  Company,  there  are  currently  no  plans,
arrangements  or  understandings  between  any Selling  Securityholders  and any
broker,  dealer or  underwriter  regarding  the sale of the Notes or  Conversion
Shares by the Selling  Securityholders.  There is no assurance  that any Selling
Securityholders  will sell any of the Notes or Conversion  Shares  offered by it
hereunder or that any of Selling  Securityholder  will not  transfer,  devise or
gift such Notes or Conversion Shares by other means not described herein.



     The Notes and the Conversion Shares may be sold from time to time in one or
more transactions at fixed offering prices,  which may be changed, or at varying
prices determined at the time of sale or at negotiated prices.  Such prices will
be  determined by the holders of such  securities  or by agreement  between such
holders  and  underwriters  or dealers who may receive  fees or  commissions  in
connection therewith.


     The  outstanding  Common Stock is listed for trading on the Nasdaq National
Market, and the Company currently intends to apply for listing of the Conversion
Shares on the Nasdaq National  Market.  The Company does not intend to apply for
listing of the Notes on any securities exchange or for inclusion of the Notes on
any  automated  quotation  system.  There is no assurance as to  development  or
liquidity of any trading market that may develop for the Notes.


     Each of Goldman, Sachs & Co., PaineWebber Incorporated and J.P. Morgan
Securities, Inc. have engaged in transactions with and performed various
investment banking and other services for the Company in the past, and may do
so from time to time in the future.

     In  order  to  comply  with  the  securities  laws of  certain  states,  if
applicable,  the Notes and Conversion Shares offered hereby will be sold in such
jurisdiction  only  through  registered  or  licensed  brokers  or  dealers.  In
addition,  in certain  states the Notes or Conversion  Shares offered hereby may
not be sold  unless  they  have been  registered  or  qualified  for sale in the
applicable  state  or  an  exemption  from  the  registration  or  qualification
requirement is available and is complied with.

     The Selling Securityholders and any brokers-dealers, agents or underwriters
that  participate  with the Selling  Securityholders  in the distribution of the
Notes or Conversion  Shares  offered  hereby may be deemed to be  "Underwriters"
within the meaning of the  Securities  Act, in which  event any  commissions  or
discounts received by such broker-dealers, agents or underwriters and any profit
on the resale of the Notes or Conversion  Shares offered hereby and purchased by
them may be  deemed  to be  underwriting  commissions  or  discounts  under  the
Securities Act.

     The Company and the Selling  Securityholders  have agreed to indemnify each
other against certain  liabilities arising under the Securities Act. The Company
has agreed to pay all  expenses  incident to the offer and sale of the Notes and
Conversion Shares offered hereby by the Selling  Securityholders  to the public,
other than the broker's commissions and underwriting discounts and commissions.

                             DESCRIPTION OF NOTES

     THE NOTES WERE ISSUED UNDER AN INDENTURE,  DATED AS OF OCTOBER 15, 1996 AND
A FIRST SUPPLEMENTAL INDENTURE, DATED AS OF SEPTEMBER 9, 1997 (COLLECTIVELY, THE
"INDENTURE"),  BETWEEN THE COMPANY AND STATE STREET BANK AND TRUST  COMPANY,  AS
TRUSTEE (THE  "TRUSTEE"),  COPIES OF WHICH ARE AVAILABLE  FOR  INSPECTION AT THE
CORPORATE  TRUST OFFICE OF THE TRUSTEE IN THE BOROUGH OF MANHATTAN,  THE CITY OF
NEW YORK.  WHEREVER  PARTICULAR  DEFINED TERMS OF THE INDENTURE  (INCLUDING  THE
NOTES AND THE VARIOUS  FORMS  THEREOF) ARE  REFERRED TO, SUCH DEFINED  TERMS ARE
INCORPORATED  HEREIN BY REFERENCE  (THE NOTES BEING REFERRED TO IN THE INDENTURE
AS "SECURITIES"). THE FOLLOWING SUMMARIES OF CERTAIN PROVISIONS OF THE INDENTURE
DO NOT PURPORT TO BE COMPLETE  AND ARE  SUBJECT TO, AND ARE  QUALIFIED  IN THEIR
ENTIRETY  BY  REFERENCE  TO,  THE  DETAILED  PROVISIONS  OF THE  NOTES  AND  THE
INDENTURE, INCLUDING THE DEFINITIONS THEREIN OF CERTAIN TERMS.


GENERAL

     The Notes are unsecured subordinated obligations of the Company, limited to
$69,000,000  aggregate principal amount and having a date of maturity of October
15, 2003.  Payment in full of the  principal  amount of the Notes will be due on
October 15, 2003 and will be payable at a price of 100% of the principal  amount
thereof.

     The Notes bear  interest  at 6% per annum from  October 15,  1996,  payable
semi-annually  on April 15 and  October  15 of each year,  commencing  April 15,
1997, until the principal thereof is paid or made available for payment,  to the
Person in whose name the Note (or any  Predecessor  Note) is  registered  at the
close of  business  on the  preceding  April 1 or October 1, as the case may be.
Interest  on the Notes at such rate will be  computed  on the basis of a 360-day
year of twelve 30-day months. Additional interest may be payable on the Notes in
the  amounts,  and  under the  circumstances,  described  under  "--Registration
Rights" below.

     The Notes will be convertible into Common Stock initially at the conversion
rate of  75.2941  shares  per  $1,000  principal  amount  of  Notes  subject  to
adjustment upon the occurrence of certain events  described under  "--Conversion
Rights," at any time prior to the close of business on the maturity date, unless
previously redeemed or repurchased.

     The Notes are  redeemable  at the option of the Company,  at any time on or
after October 15, 1999, in whole or in part, at the redemption  prices set forth
below under  "--Optional  Redemption,"  plus accrued  interest to the redemption
date.  The Notes also are subject to  repurchase by the Company at the option of
the  Holders in the event of a change of control of the  Company,  as  described
below under "--Repurchase at Option of Holders Upon a Change In Control."

     Most  of  the  Notes  were   initially   offered  and  sold  to   qualified
institutional  buyers in reliance on Rule 144A  ("RULE 144A  NOTES").  The Notes
were also offered and sold in offshore  transactions in reliance on Regulation S
("REGULATION  S NOTES") and to  institutional  accredited  investors in reliance
upon exemptions from the  registration  requirements of the Securities Act other
than  Rule  144A and  Regulation  S ("OTHER  NOTES").  The Rule  144A  Notes and
Regulation S Notes were  initially  issued in global  (i.e.,  book-entry)  form,
while the Other  Notes were issued in  certificated  (i.e.,  not in  book-entry)
form. See "--Form, Denomination, Transfer, Exchange and Book-Entry Procedures."

     The  principal  of,  premium,  if any,  and  interest  on the Notes will be
payable, and the Notes may be surrendered for registration of transfer, exchange
and  conversion,  at the  office or  agency of the  Company  in The  Borough  of
Manhattan,  The City of New York.  In addition,  payment of interest may, at the
option of the  Company,  be made by check  mailed to the  address  of the Person
entitled  thereto as it appears in the Security  Register.  See  "--Payment  and
Conversion."  Payments,   transfers,   exchanges  and  conversions  relating  to
beneficial  interests  in  Notes  in  book-entry  form  will be  subject  to the
procedures applicable to global Notes described below.

     The Company  appointed the Trustee at its Corporate  Trust Office as paying
agent,  transfer  agent,  registrar and conversion  agent for the Notes. In such
capacities,  the Trustee is responsible for, among other things, (i) maintaining
a record of the aggregate  holdings of Notes represented by each Global Note (as
defined below) and accepting Notes for exchange

                                     -17-

<PAGE>

and registration of transfer, (ii) ensuring that payments of principal, premium,
if any,  and  interest in respect of the Notes  received by the Trustee from the
Company are duly paid to DTC or its nominees,  (iii) transmitting to the Company
any notices from Holders of the Notes,  (iv)  accepting  conversion  notices and
related  documents and  transmitting  the relevant  items to the Company and (v)
delivering certificates for Common Stock issued on conversion of the Notes.

FORM, DENOMINATION, TRANSFER, EXCHANGE AND BOOK-ENTRY PROCEDURES

     The Notes were issued in fully registered form,  without interest  coupons,
in minimum denominations of $1,000 and integral multiples thereof.  Furthermore,
purchasers of Other Notes were subject to a minimum initial purchase  obligation
of $100,000 for each such purchaser. Notes were not issued in bearer form. Notes
sold were issued only against payment in immediately available funds.

     RULE 144A AND  REGULATION  S NOTES.  The Rule  144A  Notes  were  initially
represented  by one or more Notes in  registered,  global form without  interest
coupons  (collectively,  the "RESTRICTED  GLOBAL NOTE").  The Regulation S Notes
were  initially  represented  by one or more Notes in  registered,  global  form
without  interest  coupons  (collectively,  the  "REGULATION S GLOBAL NOTE" and,
together with the Restricted Global Note, the "GLOBAL NOTES").  The Global Notes
were  deposited  upon issuance with the Trustee as custodian for The  Depository
Trust Company ("DTC"),  in New York, New York, and registered in the name of DTC
or its  nominee,  in each case for credit to an account of a direct or  indirect
participant in DTC as described below.

     The Rule 144A  Notes  (including  beneficial  interests  in the  Restricted
Global Note) are subject to certain restrictions on transfer and such Notes bear
the following legend:


     THE  SECURITIES  EVIDENCED  HEREBY AND THE COMMON STOCK ISSUABLE UPON THEIR
CONVERSION HAVE NOT BEEN REGISTERED  UNDER THE U.S.  SECURITIES ACT OF 1933 (THE
"SECURITIES ACT") AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED
EXCEPT (A) BY ANY INITIAL INVESTOR THAT IS NOT A QUALIFIED  INSTITUTIONAL  BUYER
WITHIN THE MEANING OF RULE 144A UNDER THE  SECURITIES  ACT,  (1) TO A PERSON WHO
THE TRANSFEROR REASONABLY BELIEVES IS A QUALIFIED  INSTITUTIONAL BUYER ACQUIRING
FOR ITS OWN  ACCOUNT OR THE  ACCOUNT  OF A  QUALIFIED  INSTITUTIONAL  BUYER IN A
TRANSACTION  COMPLYING WITH RULE 144A, (2) IN AN OFFSHORE TRANSACTION  COMPLYING
WITH RULE 904 OF  REGULATION  S UNDER THE  SECURITIES  ACT,  (3)  PURSUANT TO AN
EXCEMPTION  FROM  REGISTRATION  UNDER THE  SECURITIES  ACT  PROVIDED BY RULE 144
THEREUNDER (IF AVAILABLE) OR (4) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT
OR (B) BY ANY INITIAL INVESTOR THAT IS A QUALIFIED INSTITUTIONAL BUYER OR BY ANY
SUBSEQUENT INVESTOR,  AS SET FORTH IN CLAUSE (A) ABOVE OR TO AN INSTITUTION THAT
IS AN ACCREDITED INVESTOR WITHIN THE MEANING OF RULE 501(A)(1),  (2), (3) OR (7)
IN A TRANSACTION  EXCEMPT FROM THE  REGISTRATION  REQUIREMENTS OF THE SECURITIES
ACT AND, IN EACH CASE (A) AND (B), IN COMPLIANCE WITH ALL APPLICABLE  SECURITIES
LAWS OF THE STATES OF THE  UNITED  STATES  AND OTHER  JURISDICTIONS,  SECURITIES
OWNED BY AN INITIAL INVESTOR THAT IS NOT A QUALIFIED INSTITUTIONAL BUYER MAY NOT
BE HELD IN BOOK-ENTRY FORM AND MAY NOT BE TRANSFERRED WITHOUT CERTIFICATION THAT
THE  TRANSFER  COMPLIES  WITH THE  FOREGOING  RESTRICTIONS,  AS  PROVIDED IN THE
INDENTURE REFERRED TO BELOW."


     The Regulation S Notes bear the following legend:

     THIS NOTE AND THE COMMON STOCK ISSUABLE UPON ITS  CONVERSION  HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT AND MAY NOT BE OFFERED, SOLD OR DELIVERED IN
THE UNITED  STATES OR TO, OR FOR THE  ACCOUNT OR  BENEFIT  OF, ANY U.S.  PERSON,
UNLESS SUCH  SECURITIES ARE REGISTERED  UNDER THE SECURITIES ACT OR AN EXEMPTION
FROM THE REGISTRATION REQUIREMENTS THEREOF IS AVAILABLE.

     Except as set forth below,  the Global Notes may be  transferred,  in whole
and not in part,  only to another nominee of DTC or to a successor of DTC or its
nominee. Beneficial interests in the Global Notes may not be exchanged for Notes
in certificated form except in the limited  circumstances  described below under
"--Exchanges  of  Book-Entry  Notes  for   Certificated   Notes."  In  addition,
beneficial  interests in the  Restricted  Global Note may not be  exchanged  for
beneficial

                                     -18-

<PAGE>

interests in the  Regulation  S Global Note or vice versa  except in  accordance
with  the  transfer  and  certification   requirements   described  below  under
"--Exchanges  between the  Restricted  Global Note and the  Regulation  S Global
Note."

     OTHER NOTES.  Other Notes will be issued only in  registered,  certificated
(I.E.,  not in book-entry) form without  interest  coupons.  Other Notes will be
subject to certain  restrictions on transfer and will bear a restrictive  legend
as described  under "Notice to Investors."  Other Notes may not be exchanged for
beneficial  interests in any Global Note except in accordance  with the transfer
and   certification   requirements   described   below  under   "--Exchanges  of
Certificated Notes for Book-Entry Notes."

     EXCHANGES  BETWEEN THE  RESTRICTED  GLOBAL NOTE AND THE REGULATION S GLOBAL
NOTE.  Beneficial  interests in the Restricted  Global Note may be exchanged for
beneficial  interests  in the  Regulation  S Global  Note and vice versa only in
connection  with a transfer  of such  interest.  Such  transfers  are subject to
compliance with the certification requirements described below.

     A beneficial interest in the Restricted Global Note may be transferred to a
person who takes  delivery in the form of an interest in the Regulation S Global
Note, only upon receipt by the Trustee of a written  certification  on behalf of
the  transferor  (in the form provided in the Indenture) to the effect that such
transfer  is being  made in  accordance  with  Rule 904 of  Regulation  S or (if
available)  Rule 144 under  the  Securities  Act (a  "REGULATION  S GLOBAL  NOTE
CERTIFICATE")  and that, if such transfer  occurs prior to the expiration of the
Restricted Period, the interest transferred will be held immediately  thereafter
through Euroclear or CEDEL.

     Any beneficial interest in one of the Global Notes that is exchanged for an
interest  in the other  Global  Note will cease to be an interest in such Global
Note and will become an interest in the other  Global  Note.  Accordingly,  such
interest  will  thereafter  be subject to all  transfer  restrictions  and other
procedures  applicable to beneficial  interests in such other Global Note for as
long as it remains such an interest.

     Any exchange of a beneficial interest in the Regulation S Global Note for a
beneficial interest in the Restricted Global Note or vice versa will be effected
in DTC by means of an  instruction  originated  by the  Trustee  through the DTC
Deposit/Withdraw at Custodian ("DWAC") system.  Accordingly,  in connection with
any such exchange,  appropriate  adjustments  will be made in the records of the
Security  Registrar  to  reflect  a  decrease  in the  principal  amount of such
Regulation S Global Note and a corresponding increase in the principal amount of
such Restricted Global Note or vice versa, as applicable.

     EXCHANGES OF BOOK-ENTRY NOTES FOR CERTIFICATED NOTES. A beneficial interest
in a Global Note may not be exchanged for a Note in certificated form unless (i)
DTC (x)  notifies  the  Company  that it is  unwilling  or unable to continue as
Depositary  for the  Global  Note  or (y) has  ceased  to be a  clearing  agency
registered under the Exchange Act and in either case the Company thereupon fails
to appoint a successor Depositary, (ii) the Company, at its option, notifies the
Trustee  in  writing  that it  elects  to cause  the  issuance  of the  Notes in
certificated  form or (iii) there shall have occurred and be continuing an Event
of Default or any event which after  notice or lapse of time or both would be an
Event of Default with  respect to the Notes.  In all cases,  certificated  Notes
delivered in exchange for any Global Note or beneficial  interests  therein will
be registered in the names, and issued in any approved denominations,  requested
by or on behalf of the Depositary (in accordance with its customary procedures).
Any certificated Note issued in exchange for an interest in the Global Note will
bear the legend  restricting  transfers  that is borne by such Global Note.  Any
such  exchange  will be  effected  through  the DWAC  System and an  appropriate
adjustment  will be made in the records of the  Security  Registrar to reflect a
decrease in the principal amount of the relevant Global Note.

     EXCHANGES OF CERTIFICATED  NOTES FOR BOOK-ENTRY NOTES.  Other Notes,  which
will be  issued  in  certificated  form,  may not be  exchanged  for  beneficial
interests in any Global Note unless such exchange  occurs in  connection  with a
transfer of such Other  Notes that  complies  with Rule 144A,  in the case of an
exchange for an interest in the  Restricted  Global Note, or Regulation S or (if
available)  Rule  144,  in  the  case  of an  exchange  for an  interest  in the
Regulation S Global Note. In addition,  in connection with any such exchange and
transfer,  the  Trustee  must  have  received  on  behalf  of the  transferor  a
Restricted Global Note Certificate or a Regulation S Global Note Certificate, as
applicable.  Any such exchange  will be effected  through the DWAC System and an
appropriate  adjustment will be made in the records of the Security Registrar to
reflect an increase in the principal amount of the relevant Global Note.

CERTAIN  BOOK-ENTRY  PROCEDURES  FOR  GLOBAL  NOTES.  THE  DESCRIPTIONS  OF  THE
OPERATIONS AND  PROCEDURES OF DTC,  EUROCLEAR AND CEDEL THAT FOLLOW ARE PROVIDED
SOLELY AS A MATTER OF  CONVENIENCE.  THESE  OPERATIONS AND PROCEDURES ARE SOLELY
WITHIN THE  CONTROL OF THE  RESPECTIVE  SETTLEMENT  SYSTEMS  AND ARE  SUBJECT TO
CHANGES BY THEM FROM TIME TO TIME. THE COMPANY TAKES NO RESPONSIBILITY FOR THESE
OPERATIONS  AND  PROCEDURES  AND URGES  INVESTORS TO CONTACT THE SYSTEM OR THEIR
PARTICIPANTS DIRECTLY TO DISCUSS THESE MATTERS.

     DTC has  advised the Company as  follows:  DTC is a limited  purpose  trust
company  organized  under  the laws of the  State of New  York,  a member of the
Federal  Reserve  System,  a  "clearing  corporation"  within the meaning of the
Uniform  Commercial  Code and a  "Clearing  Agency"  registered  pursuant to the
provisions  of  Section  17A of the  Exchange  Act.  DTC  was  created  to  hold
securities for its  participants  ("PARTICIPANTS")  and facilitate the clearance
and  settlement  of  securities   transactions   between   participants  through
electronic   book-entry  changes  in  accounts  of  its  participants,   thereby
eliminating  the  need for  physical  transfer  and  delivery  of  certificates.
Participants include securities brokers and dealers,  banks, trust companies and
clearing  corporations  and may include  certain other  organizations.  Indirect
access to the DTC system is available to other entities such as banks,  brokers,
dealers  and  trust  companies  that  clear  through  or  maintain  a  custodial
relationship  with a  participant,  either  directly  or  indirectly  ("INDIRECT
PARTICIPANTS").

     DTC has advised the Company that its current practice, upon the issuance of
the Restricted  Global Note and the  Regulation S Global Note, is to credit,  on
its  internal  system,  the  respective   principal  amount  of  the  individual
beneficial  interests  represented by such Global Notes to the accounts with DTC
of the  participants  through which such interests are to be held.  Ownership of
beneficial  interests  in the Global Notes will be shown on, and the transfer of
that ownership will be effected only through,  records  maintained by DTC or its
nominees  (with  respect  to  interests  of  participants)  and the  records  of
participants  and indirect  participants  (with  respect to interests of persons
other than participants).

     AS LONG AS DTC, OR ITS NOMINEE,  IS THE REGISTERED HOLDER OF A GLOBAL NOTE,
DTC OR SUCH NOMINEE,  AS THE CASE MAY BE, WILL BE CONSIDERED  THE SOLE OWNER AND
HOLDER OF THE NOTES  REPRESENTED  BY SUCH GLOBAL NOTE FOR ALL PURPOSES UNDER THE
INDENTURE AND THE NOTES.  Except in the limited  circumstances  described  above
under  "--Exchanges  of  Book-Entry  Notes for  Certificated  Notes,"  owners of
beneficial  interests in a Global Note will not be entitled to have any portions
of such Global Note  registered in their names,  will not receive or be entitled
to  receive  physical  delivery  of  Notes  in  definitive  form and will not be
considered  the owners or Holders of the Global  Note (or any Notes  represented
thereby) under the Indenture or the Notes.

     Investors may hold their  interests in the Restricted  Global Note directly
through DTC, if they are  participants  in such system,  or  indirectly  through
organizations  (including  Euroclear and CEDEL) which are  participants  in such
system.  Investors  may hold their  interests  in the  Regulation  S Global Note
through  CEDEL  or  Euroclear,  if they are  participants  in such  systems,  or
indirectly through  organizations which are participants in such systems.  After
the  expiration of the Restricted  Period (but not earlier),  investors may also
hold their interests in the Regulation S Global Note through organizations other
than CEDEL and  Euroclear  that are  participants  in the DTC system.  CEDEL and
Euroclear will hold interests in the Regulation S Global Note on behalf of their
participants through customers' securities accounts in their respective names on
the books of their respective depositories. The depositories, in turn, will hold
such interests in the Regulation S Global Note in customers' securities accounts
in the depositories'  names on the books of DTC. All interests in a Global Note,
including  those  held  through  Euroclear  or  CEDEL,  will be  subject  to the
procedures and  requirements of DTC. Those interests held through  Euroclear and
CEDEL will also be subject to the  procedures and  requirements  of such system.
Transfers  and  exchanges  of interests in a Global Note will also be subject to
the procedures  described above under "--Exchanges between the Restricted Global
Note and the Regulation S Global Note," if applicable.

     The laws of some states require that certain persons take physical delivery
in definitive  form of securities  that they own.  Consequently,  the ability to
transfer beneficial interests in a Global Note to such persons may be limited to
that extent.  Because DTC can act only on behalf of its  participants,  which in
turn act on behalf of indirect  participants and certain banks, the ability of a
person having  beneficial  interests in a Global Note to pledge such interest to
persons or entities that do not participate in the DTC system, or otherwise take
actions in respect of such interests,  may be affected by the lack of a physical
certificate evidencing such interests.

     Payments of the principal of, premium, if any, and interest on Global Notes
will be made to DTC or its nominee as the registered owner thereof.  Neither the
Company,  the  Trustee  nor  any  of  their  respective  agents  will  have  any
responsibility

                                     -20-

<PAGE>

or  liability  for any aspect of the records  relating  to or  payments  made on
account  of  beneficial   ownership   interests  in  the  Global  Notes  or  for
maintaining,  supervising or reviewing any records  relating to such  beneficial
ownership interests.

     The Company expects that DTC or its nominee, upon receipt of any payment of
principal or interest in respect of a Global Note representing any Notes held by
it or its nominee, will immediately credit participants'  accounts with payments
in  amounts  proportionate  to  their  respective  beneficial  interests  in the
principal  amount of such  Global Note for such Notes as shown on the records of
DTC or its nominee.  The Company also expects that payments by  participants  to
owners  of   beneficial   interests  in  such  Global  Note  held  through  such
participants will be governed by standing  instructions and customary practices,
as is now the case with securities held for the accounts of customers registered
in "street name." Such payments will be the responsibility of such participants.

     Except  for  trades  involving  only  Euroclear  and  CEDEL   participants,
interests  in the Global  Notes will trade in DTC's  Same-Day  Funds  Settlement
System and secondary  market  trading  activity in such interests will therefore
settle in  immediately  available  funds,  subject in all cases to the rules and
procedures of DTC and its participants.  Transfers  between  participants in DTC
will be effected in  accordance  with DTC's  procedures,  and will be settled in
same-day funds.  Transfers  between  participants in Euroclear and CEDEL will be
effected in the  ordinary  way in  accordance  with their  respective  rules and
operating procedures.

     Subject  to  compliance   with  the  transfer  and  exchange   restrictions
applicable  to the Notes  described  elsewhere  herein,  cross-market  transfers
between DTC participants,  on the one hand, and Euroclear or CEDEL participants,
on the other hand,  will be effected  by DTC in  accordance  with DTC's rules on
behalf of Euroclear or CEDEL, as the case may be, by its respective  depositary;
however, such cross-market transactions will require delivery of instructions to
Euroclear or CEDEL,  as the case may be, by the  counterparts  in such system in
accordance  with the rules and procedures and within the  established  deadlines
(Brussels time) of such system. Euroclear or CEDEL, as the case may be, will, if
the transaction meets its settlement  requirements,  deliver instructions to its
respective depository to take action to effect final settlement on its behalf by
delivering or receiving interests in the relevant Global Note in DTC, and making
or receiving  payment in accordance  with normal  procedures  for same-day funds
settlement applicable to DTC. Euroclear  participants and CEDEL participants may
not deliver instructions directly to the depositories for Euroclear or CEDEL.

     Because of time zone differences,  the securities account of a Euroclear or
CEDEL participant purchasing an interest in a Global Note from a DTC participant
will be  credited,  and any such  crediting  will be  reported  to the  relevant
Euroclear or CEDEL participant,  during the securities settlement processing day
(which must be a business day for Euroclear and CEDEL) immediately following the
DTC settlement date. Cash received in Euroclear or CEDEL as a result of sales of
interests in a Global Note by or through a Euroclear or CEDEL  participant  to a
DTC participant  will be received with value on the DTC settlement date but will
be  available  in the  relevant  Euroclear  or CEDEL cash account only as of the
business day for Euroclear or CEDEL following the DTC settlement date.

     DTC has advised the Company  that it will take any action  permitted  to be
taken by a holder of Notes  (including the presentation of Notes for exchange as
described  below and the  conversion  of Notes) only at the  direction of one or
more  participants  to whose  account with DTC interests in the Global Notes are
credited and only in respect of such portion of the aggregate  principal  amount
of the Notes as to which such participant or participants has or have given such
direction. However, if there is an Event of Default (as defined below) under the
Notes, DTC reserves the right to exchange the Global Notes for legended Notes in
certificated form, and to distribute such Notes to its participants.

     Although DTC,  Euroclear and CEDEL have agreed to the foregoing  procedures
in order to facilitate transfers of beneficial ownership interests in the Global
Notes  among  participants  of DTC,  Euroclear  and  CEDEL,  they  are  under no
obligation  to  perform  or  continue  to  perform  such  procedures,  and  such
procedures may be discontinued at any time. None of the Company, the Trustee nor
any of their respective agents will have any  responsibility for the performance
by DTC,  Euroclear and CEDEL,  their  participants  or indirect  participants of
their  respective  obligations  under the rules and procedures  governing  their
operations, including maintaining, supervising or reviewing the records relating
to, or payments  made on account of,  beneficial  ownership  interests in Global
Notes.

PAYMENT AND CONVERSION

     The  principal  of the  Notes  will be  payable  in U.S.  dollars,  against
surrender  thereof at the office or agency of the Company  designated  by it for
such purpose in the Borough of Manhattan, The City of New York, and at any other
office or agency of the Company maintained for such purpose, in U.S. currency by
dollar check or by transfer to a dollar account (such a transfer to be made only
to a Holder of an aggregate  principal  amount of Notes in excess of  $2,000,000
and only if such Holder shall have furnished wire instructions in writing to the
Trustee no later than 15 days prior to the relevant  payment date) maintained by
the Holder with a bank in the United  States.  Payment of interest on a Note may
be made by dollar check mailed to the address of the person entitled  thereto as
such  address  shall  appear  in  the  Security  Registrar,   or,  upon  written
application by the Holder to the Security  Registrar setting forth  instructions
not later than the relevant Record Date, by transfer to a dollar account (such a
transfer to be made only to a Holder of an aggregate  principal  amount of Notes
in excess of  $2,000,000  and only if such  Holder  shall  have  furnished  wire
instructions  in  writing  to the  Trustee  no later  than 15 days  prior to the
relevant  payment  date)  maintained  by the  Holder  with a bank in the  United
States.


     Any  payment on a Note due on any day which is not a Business  Day need not
be made on such day,  but may be made on the next  succeeding  Business Day with
the same force and  effect as if made on such due date,  and no  interest  shall
accrue on such payment for the period from and after such date.  "Business Day,"
when used with respect to any place of payment, place of conversion or any other
place, as the case may be, means each Monday, Tuesday,  Wednesday,  Thursday and
Friday  which  is not a day on  which  banking  institutions  in such  place  of
payment,  place of conversion or other place, as the case may be, are authorized
or obligated by law or executive order to close.

     Notes may be  surrendered  for  conversion  at the  office or agency of the
Company in the Borough of  Manhattan,  The City of New York, at any other office
or agency of the Company maintained for such purpose and at the office or agency
of any  additional  conversion  agent  appointed by the Company.  In the case of
Global Notes,  conversion will be effected by DTC upon notice from the holder of
a  beneficial  interest  in a  Global  Note in  accordance  with its  rules  and
procedures. Notes surrendered for conversion must be accompanied by a conversion
notice and any  payments in respect of  interest,  as  applicable,  as described
below under "-Conversion Rights."

REGISTRATION RIGHTS

     The  holders of the Notes and the Common  Stock  issuable  upon  conversion
thereof are entitled to the benefits of a Registration  Rights Agreement,  dated
as  of  October  15,  1996,   between  the  Company  and  the  Purchasers   (the
"Registration Rights Agreement"). Pursuant to the Registration Rights Agreement,
the Company  has, at its  expense,  filed a shelf  registration  statement  (the
"Shelf  Registration  Statement") with the Commission with respect to resales of
the Notes and the Common Stock issuable upon conversion  thereof  (collectively,
the  "Registrable  Securities")  and agreed for the benefit of the Holders  from
time to time and the holders  from time to time of the Common  Stock issued upon
conversion  thereof that it will, at its expense,  (i) use its  reasonable  best
efforts to cause such Shelf  Registration  Statement to be declared effective by
the  Commission as promptly as  practicable  but within 180 days after the first
date of original issuance of the Notes, and (ii) use its reasonable best efforts
to maintain such Shelf Registration  Statement  continuously effective under the
Securities Act until the date (the  "Expiration  Date") which is the earliest of
the dates  described  in the  following  clauses (a), (b) and (c): (a) the third
annual  anniversary  of the  later of the (x) date of the  effectiveness  of the
Shelf  Registration  Statement (the "effective time") and (y) the latest date of
original  issuance  of the Notes,  (b) such time as all  Registrable  Securities
covered by the Shelf Registration Statement have been sold pursuant to the Shelf
Registration  Statement,  transferred  pursuant to Rule 144 under the Securities
Act or other wise  transferred  in a manner that  results in a new  security not
subject  to  transfer  restrictions  under the  Securities  Act being  delivered
pursuant to the Indenture  and (c) such time as, in the opinion of counsel,  all
of the Registrable  Securities held by nonaffiliates of the Company are eligible
for resale  pursuant to Rule 144(k) (or any  successor or analogous  rule) under
the Securities Act and the legend described under "Notice to Investors" has been
removed from such Registrable  Securities.  Notwithstanding  the foregoing,  the
Company will be permitted to suspend the use of the  prospectus  that is part of
the Shelf Registration Statement for a period not to exceed 30 days in any three
month period or 60 days in any 12 month period (with any such period referred to
as a "blackout  period"),  if the Board of Directors  of the Company  shall have
determined  in good faith  that it is in the best  interests  of the  Company to
suspend such use and the Company  provides  the Holders  with written  notice of
such suspension.

                                     -22-

<PAGE>


The Shelf  Registration  Statement was declared  effective on April 11, 1997. In
the event that the Shelf  Registration  Statement  ceases to be effective or the
Company  suspends  the  use  of  the  prospectus  that  is  part  of  the  Shelf
Registration  Statement  (whether pursuant to a blackout period or otherwise) at
any time after the effective time and prior to the Expiration  Date for a period
in excess of 60 days,  whether or not  consecutive,  during any 12-month period,
then the  interest  rate  borne by the Notes  shall  increase  by an  additional
one-half  percent  (0.50%) of the  principal  amount  thereof per annum from and
including  the 61st day of  ineffectiveness  or  suspension to but excluding the
first day on which the Shelf Registration Statement thereafter becomes effective
or the prospectus  becomes  available for use. Any reference  herein,  or in the
Indenture  or the  Notes,  to  interest  shall  be  deemed  also to refer to any
additional interest that may be payable as described in this paragraph.


     The Registration  Rights  Agreement  provides that holder of 33 1/3% of the
Registrable   Securities  may  elect  to  have  one  underwritten   offering  of
Registrable  Securities.  The managing underwriter(s) for any such offering must
be selected by Holder of 50% of the Registrable Securities to be included in the
underwritten offering and must be reasonably acceptable to the Company.

     The Company  will pay all fees and  expenses  incident to the filing of the
Shelf  Registration  Statement and maintaining its  effectiveness for resales of
Registrable  Securities.  In addition, in the event of an underwritten offering,
the Company will pay the fees and  expenses  incurred by it in  connection  with
such offering  including those of its independent  counsel and accountants,  and
will also pay up to a maximum of $75,000  for the fees and  expenses of a single
counsel  selected by holders of not less than 25% of the Registrable  Securities
included in such offering to represent  them in connection  with such  offering.
The holders  participating  in such offering will be responsible  (on a pro rata
basis based on the principal amount of Registrable  Securities  included in such
offering) for all fees and expenses of such counsel in excess of $75,000. Except
as provided in the preceding  sentence,  each holder of  Registrable  Securities
included  in the  Shelf  Registration  Statement  will  be  responsible  for all
underwriting  discounts and  commissions  payable in connection with the sale of
such holders of Registrable  Securities and any other fees and expenses incurred
by it in connection with the Shelf Registration Statement.

     In the Registration  Rights Agreement,  the Company has agreed to indemnify
the holders of Registrable  Securities  against certain  liabilities,  including
liabilities   under  the  Securities  Act,  provided  that  any  holder  seeking
indemnification did not use a prospectus during a blackout period or an outdated
prospectus after the Company has provided such holder an updated prospectus, and
each  holder  of  Registrable  Securities  included  in the  Shelf  Registration
Statement  is  obligated  to  indemnify  the  Company,  any other holder and any
underwriters participating in the offering of Registrable Securities against any
liability with respect to information furnished by such holder in writing to the
Company (including the information in a Selling Securityholder's  Questionnaire)
expressly for use in the Shelf Registration Statement.

     This summary of certain  provisions of the  Registration  Rights  Agreement
does not purport to be complete and is subject to, and qualified in its entirety
by reference to, all the provisions of the Registration Rights Agreement, a copy
of the  form of  which  will be made  available  to  holders  of  Notes  (i) for
inspection  at the offices of the Company  specified  above or at the  Corporate
Trust  Office of the Trustee in the City of New York or (ii) upon request to the
Company.

CONVERSION RIGHTS

     The  Holder of any Note will have the right,  at the  Holder's  option,  to
convert  any  portion  of the  principal  amount of a Note  that is an  integral
multiple of $1,000 into shares of Common Stock at any time following October 15,
1996 unless previously redeemed or repurchased,  at a conversion rate of 75.2941
shares per $1,000 principal  amount of Notes (the "CONVERSION  RATE") subject to
adjustment as described below. The right to convert a Note called for redemption
or  delivered  for  repurchase  will  terminate  at the close of business on the
Redemption Date or Repurchase Date for such Note, unless the Company defaults in
making the payment due upon redemption or repurchase, as the case may be.

                                     -23-

<PAGE>

     The  right of  conversion  attaching  to any Note may be  exercised  by the
Holder by  delivering  the Note at the  office or agency of the  Company  in the
Borough of Manhattan, The City of New York, at any other office or agency of the
Company  maintained  for  such  purpose  and  at the  office  or  agency  of any
additional  conversion  agent  appointed by the Company,  accompanied  by a duly
signed and completed notice of conversion,  a copy of which may be obtained from
the Trustee and any conversion  agent.  The conversion  date will be the date on
which the Note and the duly signed and  completed  notice of  conversion  are so
delivered.  As promptly as  practicable  on or after the  conversion  date,  the
Company will issue and deliver to the Trustee a certificate or certificates  for
the number of full shares of Common Stock  issuable  upon  conversion,  together
with  payment in lieu of any  fraction of a share or, at the  Company's  option,
rounded up to the next whole number of shares;  such certificate will be sent by
the Trustee to the Conversion  Agent for delivery to the Holder.  Such shares of
Common Stock  issuable  upon  conversion of the Notes,  in  accordance  with the
provisions of the Indenture,  will be fully paid and non-assessable and may bear
restrictive legends governing their transfer as provided in the Indenture.

     Any Note  surrendered  for  conversion  during the period from the close of
business on any Regular Record Date next preceding any Interest  Payment Date to
the opening of business on such Interest Payment Date (except Notes (or portions
thereof)  called for  redemption  on a  Redemption  Date or  repurchasable  on a
Repurchase  Date  occurring,  in  either  case,  within  such  period)  must  be
accompanied  by  payment  of an amount  equal to the  interest  payable  on such
Interest  Payment Date on the principal  amount of such Notes being  surrendered
for conversion.  The interest  payable on any Interest Payment Date with respect
to any Note (or  portion  thereof,  if  applicable)  which has been  called  for
redemption  on a Redemption  Date,  or is  repurchasable  on a Repurchase  Date,
occurring,  in either case,  during the period from the close of business on the
Regular Record Date next preceding such Interest  Payment Date to the opening of
business on such Interest Payment Date, which Note is surrendered for conversion
(in whole or in part) during such period,  shall be paid upon  conversion to the
Holder in an amount  equal to the  interest  that would have been payable on the
portion of such Note that is being called for redemption or is being repurchased
and is being  converted  if such  portion had been  converted as of the close of
business on such Interest  Payment Date. The interest so payable on any Interest
Payment  Date in respect of any Note (or  portion  thereof,  as the case may be)
which  has not been  called  for  redemption  on a  Redemption  Date,  or is not
eligible for repurchase on a Repurchase Date, occurring,  in either case, during
the period from the close of business on the Regular  Record Date next preceding
such Interest  Payment Date to the opening of business on such Interest  Payment
Date,  which Note (or portion  thereof,  as the case may be) is surrendered  for
conversion  during such  period,  shall be paid to the Holder of such Note as of
such Regular  Record  Date.  Interest  payable on any  Interest  Payment Date in
respect of any Note surrendered for conversion on or after such Interest Payment
Date shall be paid to the Holder of such Note as of the next  preceding  Regular
Record Date, notwithstanding the exercise of the right of conversion.

     As a result of the foregoing  provisions,  Holders that surrender Notes for
conversion  on a date that is not an Interest  Payment Date will not receive any
interest for the period from the Interest  Payment Date next  preceding the date
of conversion  to the date of  conversion  or for any later period,  even if the
Notes are  surrendered  after a notice of redemption  has been given (except for
the payment of interest on Notes called for  redemption on a Redemption  Date or
repurchasable  on a  Repurchase  Date  between  a  Regular  Record  Date and the
Interest Payment Date to which it relates,  as provided above). No other payment
or  adjustment  for  interest,  or for any dividends in respect of Common Stock,
will be made upon  conversion.  Holders of Common Stock  issued upon  conversion
will not be entitled to receive any dividends payable to holders of Common Stock
as of any record date before the close of business on the  conversion  date.  No
fractional  shares will be issued upon  conversion  but,  in lieu  thereof,  the
Company will calculate an appropriate amount to be paid in cash on the basis set
forth in the Indenture  or, at its option,  round up to the next whole number of
shares.

     A Holder  delivering a Note for conversion  will not be required to pay any
taxes  or  duties  in  respect  of the  issue or  delivery  of  Common  Stock on
conversion.  However,  the Company  shall not be required to pay any tax or duty
which  may be  payable  in  respect  of any  transfer  involved  in the issue or
delivery  of the  Common  Stock in a name  other  than that of the Holder of the
Note.  Certificates  representing  shares of Common  Stock will not be issued or
delivered  unless the person  requesting  such issue has paid to the Company the
amount of any such tax or duty or has  established  to the  satisfaction  of the
Company that such tax or duty has been paid.

     The Conversion Rate is subject to adjustment in certain  events,  including
(a)  dividends  (and other  distributions)  payable in Common Stock on shares of
capital stock of the Company, (b) the issuance to all holders of Common Stock of
certain rights,  options or warrants entitling them to subscribe for or purchase
Common Stock at less than the then current market price  (determined as provided
in the  Indenture)  of  Common  Stock as of the  record  date  for  shareholders
entitled to

                                     -24-

<PAGE>

receive such rights,  options or warrants,  (c)  subdivisions,  combinations and
reclassifications  of Common Stock,  (d)  distributions to all holders of Common
Stock of evidences of  indebtedness  of the Company,  shares of capital stock or
other property  (including  securities,  but excluding those dividends,  rights,
options,   warrants  and   distributions   referred  to  above,   dividends  and
distributions  paid  exclusively  in cash  and  distributions  upon  mergers  or
consolidations   to  which  the  fifth  succeeding   paragraph   applies),   (e)
distributions  consisting  exclusively  of cash  (excluding  any cash portion of
distributions  referred to in (d) above,  or cash  distributed  upon a merger or
consolidation to which the fifth succeeding paragraph applies) to all holders of
Common Stock in an aggregate amount that,  combined together with (i) other such
all-cash  distributions  made within the preceding 12 months in respect of which
no adjustment has been made and (ii) any cash and the fair market value of other
consideration  payable in respect of any tender  offer by the  Company or any of
its  Subsidiaries  for Common Stock concluded  within the preceding 12 months in
respect of which no  adjustment  has been made,  exceeds  12.5% of the Company's
market capitalization (being the product of the then current market price of the
Common Stock and the number of shares of Common Stock then  outstanding)  on the
record date for such distribution and (f) the successful  completion of a tender
offer made by the  Company or any of its  subsidiaries  for Common  Stock  which
involves an aggregate  consideration  that, together with (i) any cash and other
consideration  paid in a tender offer by the Company or any of its  Subsidiaries
for Common Stock expiring within the 12 months  preceding the expiration of such
tender  offer  in  respect  of which no  adjustment  has been  made and (ii) the
aggregate amount of any such all-cash  distributions referred to in (e) above to
all holders of Common Stock within the 12 months  preceding  the  expiration  of
such tender  offer in respect of which no  adjustments  have been made,  exceeds
12.5% of the Company's  market  capitalization  on the expiration of such tender
offer.  The Company  reserves the right to make such increases in the conversion
rate in addition to those  required in the foregoing  provisions as it considers
to be  advisable  in order that any event  treated for income tax  purposes as a
dividend or  distribution of stock or issuance of rights or warrants to purchase
or subscribe for stock will not be taxable to the  recipients.  No adjustment of
the conversion rate will be required to be made until the cumulative adjustments
amount to 1.0% or more of the  conversion  rate.  The Company  shall compute any
adjustments  to the  conversion  price  pursuant to this paragraph and will give
notice to the Holders of any such adjustments.

     Notwithstanding  the  foregoing,  in the event that the Company  decides to
distribute  to all holders of the Common Stock common stock  ("OTHER  STOCK") of
another corporation ("OTHER  CORPORATION") and actually makes such distribution,
then in lieu of making the  adjustment  to the  Conversion  Rate required by the
Indenture in respect of such  distribution,  the  Company,  at its option if the
requirements described below are satisfied,  may place in escrow for the benefit
of the Holders a number of shares of Other Stock equal to the  aggregate  number
of shares of Other  Stock that  would be  distributed  to all  Holders as of the
record  date for such  distribution  in respect  of the  shares of Common  Stock
issuable on  conversion  of their Notes,  had such Notes been  converted on such
date. In the event the Company  exercises this option,  upon all  conversions of
Notes from time to time after such  record  date,  Holders  will  receive  their
respective  pro rata  portions  of the Other Stock held in escrow in addition to
Common  Stock.  (Holders  converting  after  such  record  date and  before  the
distribution  date will receive a due bill for the relevant  number of shares of
Other Stock, which will be distributed on the distribution  date.) Upon any such
conversion, a Holder's pro rata portion will equal the principal amount of Notes
being  converted  divided  by  the  aggregate  principal  amount  of  all  Notes
Outstanding on the record date for such distribution.

     The Company may exercise the option  described in the  preceding  paragraph
only if: (i) the  aggregate  number of shares of Other Stock so placed in escrow
does not exceed 33 1/3% of the aggregate number of all publicly traded shares of
Other Stock and (ii) the total market capitalization of the Other Corporation is
at least $50 million.  Compliance with the two requirements described above will
be  determined  as of the date on which the  distribution  of Other Stock to the
holders of Common Stock is  completed,  PROVIDED that if, on the record date for
such  distribution,  shares of Other Stock are  already  publicly  traded,  then
compliance with these requirements will be determined as of such record date. If
these  requirements are to be satisfied as of the distribution date but are not,
the Company will adjust the Conversion  Rate in respect of such  distribution as
required by the Indenture,  retroactively to the day after such record date (and
any Holder that receives a due bill upon  conversion  after such record date but
before  the  distribution  date  will  receive  Common  Stock  pursuant  to such
adjustment, rather than Other Stock). Shares of Other Stock will be deemed to be
"publicly  traded"  if such  shares  are not held by an  affiliate  of the Other
Corporation (other than the Company), may be freely traded by the holders (other
than the Company) without  registration under the Securities Act, are of a class
of securities  registered under Section 12(b) or (g) of the Exchange Act and are
either  approved for trading in the Nasdaq  National Market or listed on the New
York  Stock  Exchange  or  the  American  Stock  Exchange.   The  "total  market
capitalization"  of the Other Corporation for these purposes will be the product
of the market  price per share of Other Stock on the  applicable  date times the
aggregate  number  of shares  of Other  Stock  (other  than  shares  held by any
affiliate of the Other  Corporation  other than the Company)  outstanding on the
applicable date. In the event that the aggregate number of shares to be escrowed
for the benefit of the Holders would exceed

                                     -25-

<PAGE>

the 33 1/3% limit described in clause (i) above,  the Company may still exercise
its option to escrow shares of Other Stock if (a) the number of shares  escrowed
equals 33 1/3% of the aggregate  number of publicly traded shares of Other Stock
on the applicable  date and (b) the  Conversion  Rate is adjusted as required by
the Indenture as if the aggregate number of shares of Other Stock distributed to
holders of Common Stock  consisted  only of the remaining  number of shares that
would have been escrowed  pursuant to this  paragraph but for the  limitation in
clause (i) above,  to the extent so  distributed.  (In such a case, any due bill
received by a Holder as described  above will be  appropriately  adjusted by the
Company as necessary.)

     If the  Company  exercises  its  option as  described  above,  it will make
appropriate  adjustment in the number of shares of Other Stock  deliverable upon
conversion of Notes in light of any event  occurring with respect to Other Stock
after the applicable date referred to above, in each case in a manner consistent
with the  provisions of the Indenture  relating to adjustment of the  Conversion
Rate to the greatest extent possible,  subject to the following sentence. If, as
a result of any such  adjustment,  the  Company  would be required to deliver on
conversion  of all Notes  then  Outstanding  a larger  number of shares of Other
Stock  than the  number  then held in  escrow  (together  with any  shares to be
received in respect of those in escrow as a result of such  event),  the Company
will, in lieu of making such adjustment to the extent necessary,  provide for an
amount of cash equal to the fair market value of such  adjustment (to the extent
not made) to be delivered upon conversion of any Note thereafter, in addition to
the shares of Other Stock otherwise deliverable.  In addition, in the event that
any Other  Stock held in escrow at any time (x) ceases to be a class  registered
under Section 12(b) or (g) of the Exchange Act, (y) ceases to be either approved
for  trading  in the  Nasdaq  National  Market or  listed on the New York  Stock
Exchange or the  American  Stock  Exchange or (z) would not be freely  tradeable
under the Securities  Act when  delivered  upon  conversion of Notes to a Holder
that is not an affiliate of the Other Corporation,  the Company will provide for
cash to be delivered upon subsequent  conversions of Notes in lieu of such Other
Stock,  in each case in an amount equal to the fair market value of the relevant
portion of such Other Stock  immediately prior to such event, in the case of (x)
or (y),  or  immediately  prior  to such  conversion,  in the  case of (z).  Any
additional  shares of Other Stock  required to be  delivered  on  conversion  of
Notes,  and any  cash  required  to be  delivered  in lieu of  Other  Stock,  as
described  above will be placed in escrow for the  benefit of the Holders of the
Notes  (with  any  interest  earned on such cash  being for the  account  of the
Company).

     Notwithstanding the foregoing, the Company may, in lieu of placing any cash
in  escrow  as  described  in the  preceding  paragraph,  elect  to  adjust  the
Conversion Rate so that, upon any subsequent conversion, a Holder of Notes would
receive an incremental number of shares of Common Stock equal to the fair market
value of the  portion  of such  cash that it would  have  received  absent  such
adjustment.  All determinations regarding adjustments in the number of shares of
Other Stock,  the substitution of cash for Other Stock and any adjustment in the
Conversion Rate in lieu of the  substitution of cash are to be made by the Board
of Directors  of the Company in good faith,  and any such  determination  by the
Board will be conclusive.

     In case of any  consolidation or merger of the Company with or into another
Person or any merger of another  Person  into the  Company  (other than a merger
which  does  not  result  in  any  reclassification,   conversion,  exchange  or
cancellation  of the  Common  Stock),  or in the case of any  conveyance,  sale,
transfer or lease of all or  substantially  all of the  properties and assets of
the Company,  each Note then outstanding will, without the consent of the Holder
of any Note,  become  convertible  only into the kind and amount of  securities,
cash and other  property  receivable  upon  such  consolidation,  merger,  sale,
conveyance,  lease or other  transfer  by a holder  of the  number  of shares of
Common  Stock into which such Note was  convertible  immediately  prior  thereto
(assuming  such holder of Common Stock failed to exercise any rights of election
and that such Note was then convertible).

     The  Company  from time to time may  increase  the  Conversion  Rate by any
amount for any period of at least 20 days,  in which case the Company shall give
at least 15 days' notice of such increase,  if the Board of Directors has made a
determination  that such increase would be in the best interests of the Company,
which  determination  shall be conclusive.  No such increase shall be taken into
account for  purposes  of  determining  whether the closing  price of the Common
Stock (and, if  applicable,  the fair market value of any Other Stock or related
property then held in escrow) exceeds the Conversion Price (as defined below) by
105% in connection with an event which otherwise would be a Change in Control.

     If at any  time  the  Company  makes  a  distribution  of  property  to its
shareholders  which  would be taxable  to such  shareholders  as a dividend  for
federal income tax purposes (E.G., distributions of evidences of indebtedness or
assets of the  Company,  but  generally  not stock  dividends on Common Stock or
rights to  subscribe  for  Common  Stock)  and,  pursuant  to the  anti-dilution
provisions  of the  Indenture,  the  number  of  shares  into  which  Notes  are
convertible is increased, such

                                     -26-

<PAGE>

increase may be deemed for federal income tax purposes to be the payment of a
taxable dividend to Holders of Notes. See "United States Taxation--United
States Holders--Dividends".

SUBORDINATION

     The payment of the  principal  of,  premium,  if any,  and interest on, the
Notes  (including  amounts  payable on any  redemption  or  repurchase)  will be
subordinated in right of payment to the extent set forth in the Indenture to the
prior full and final  payment of all Senior Debt of the Company.  "Senior  Debt"
means  the  principal  of (and  premium,  if any) and  interest  (including  all
interest  accruing  subsequent to the  commencement of any bankruptcy or similar
proceeding,  whether or not a claim for post-petition interest is allowable as a
claim in any such  proceeding)  on,  and all fees and other  amounts  (including
collection  expenses,  attorney's  fees and late charges) owing with respect to,
the following,  whether direct or indirect,  absolute or contingent,  secured or
unsecured,  due or to become due,  outstanding  at the date of  execution of the
Indenture or thereafter  incurred,  created or assumed:  (a) indebtedness of the
Company for money borrowed or evidenced by bonds,  debentures,  notes or similar
instruments,  (b)  reimbursement  obligations  of the  Company  with  respect to
letters of credit,  bankers'  acceptances and similar  facilities issued for the
account of the Company, (c) every obligation of the Company issued or assumed as
the deferred  purchase  price of property or services  purchased by the Company,
excluding any trade payables and other accrued current  liabilities  incurred in
the ordinary course of business,  (d) obligations of the Company as lessee under
leases  required  to be  capitalized  on the balance  sheet of the lessee  under
United States generally accepted accounting  principles,  (e) obligations of the
Company under interest rate and currency swaps, caps, floors, collars or similar
arrangements intended to protect the Company against fluctuations in interest or
currency  exchange rates,  (f)  indebtedness of others of the kinds described in
the  preceding  clauses (a) - (e) that the Company has  assumed,  guaranteed  or
otherwise  assured  the payment  thereof,  directly  or  indirectly,  and/or (g)
deferrals, renewals, extensions and refundings of, or amendments,  modifications
or supplements  to, any  indebtedness  or obligation  described in the preceding
clauses  (a) through (f) whether or not there is any notice to or consent of the
Holders of Notes;  PROVIDED,  HOWEVER,  that the following  shall not constitute
Senior Debt: (i) any particular  indebtedness  or obligation that is owed by the
Company to any of its direct and indirect  Subsidiaries  and (ii) any particular
indebtedness,  deferral,  renewal,  extension  or  refunding  if it is expressly
stated in the governing terms or in the assumption thereof that the indebtedness
involved  is  not  senior  in  right  of  payment  to the  Notes  or  that  such
indebtedness is PARI PASSU with or junior to the Notes.

     No payment on account of  principal,  premium,  if any,  or interest on the
Notes may be made if (a) there  shall  have  occurred  and be  continuing  (i) a
default in the payment of any Senior Debt or (ii) any other default with respect
to any Senior Debt  permitting  the holders  thereof to accelerate  the maturity
thereof,  provided that, in the case of this clause (ii), such default shall not
have  been  cured or waived or  ceased  to exist  after  written  notice of such
default  shall have been given to the  Company  and the Trustee by any holder of
Senior Debt, or (b) in the event any judicial  proceeding  shall be pending with
respect  to  any  such  default  in  payment  or  event  of  default.  Upon  any
acceleration  of the  principal due on the Notes or payment or  distribution  of
assets of the Company to creditors upon any dissolution, winding up, liquidation
or  reorganization,   whether  voluntary  or  involuntary,   or  in  bankruptcy,
insolvency,  receivership  or other  proceedings,  all amounts due on all Senior
Debt must be paid in full  before  the  Holders  of the Notes  are  entitled  to
receive any payment. By reason of such subordination, in the event of insolvency
of the  Company,  creditors  of the  Company  who are holders of Senior Debt may
recover more, ratably, than the Holders of the Notes, and such subordination may
result in a reduction or elimination of payments to the Holders of the Notes. As
of  the  date  of  this  Offering  Circular,  the  Company  had no  Senior  Debt
outstanding.

     In addition, the Notes will be effectively subordinated to all indebtedness
and other  liabilities  (including trade payables and lease  obligations) of the
Company's subsidiaries. As of the date hereof, the Company has no subsidiaries.

     The  Indenture  does not limit the  ability  of the  Company  or any of its
subsidiaries to incur indebtedness, including Senior Debt.

OPTIONAL REDEMPTION

     The Notes may not be redeemed prior to the close of business on October 14,
1999. Thereafter,  the Notes may be redeemed, in whole or in part, at the option
of the  Company,  upon not less than 30 nor more than 60 days'  prior  notice as
provided under "--Notices" below, at the redemption prices set forth below. Such
redemption prices (expressed as a percentage of principal amount) are as follows
for the 12-month period beginning on October 15 of the following years:

               2002                              100.857

and thereafter at a redemption price equal to 100% of the principal  amount,  in
each case together with accrued interest to the redemption date.

REPURCHASE AT OPTION OF HOLDERS UPON A CHANGE IN CONTROL

     If a Change in Control  (as  defined  below)  occurs,  each Holder of Notes
shall  have the  right,  at the  Holder's  option,  to  require  the  Company to
repurchase all of such Holder's  Notes,  or any portion of the principal  amount
thereof  that is equal to $1,000  or an  integral  multiple  of $1,000 in excess
thereof,  on the date (the "REPURCHASE  DATE") that is 45 days after the date of
the Company Notice (as defined  below),  at a price in cash equal to 100% of the
principal amount of the Notes to be repurchased,  together with interest accrued
to the Repurchase Date (the "REPURCHASE PRICE").

     The Company may, at its option,  in lieu of paying the Repurchase  Price in
cash, pay the Repurchase  Price in Common Stock.  The number of shares of Common
Stock tendered in payment shall be determined by dividing the  Repurchase  Price
by the value of the Common  Stock,  which for this purpose shall be equal to 95%
of the  average  of the  closing  bid  prices of the  Common  Stock for the five
consecutive Trading Days ending on and including the third Trading Day preceding
the  Repurchase  Date.  Such  payment may not be made in Common Stock unless the
Company  satisfies  certain   conditions  with  respect  thereto  prior  to  the
Repurchase Date as provided in the Indenture.

     On or before the 30th day after the occurrence of a Change in Control,  the
Company is obligated to give to all Holders of the Notes notice,  as provided in
the  Indenture  (the  "COMPANY  NOTICE"),  of the  occurrence  of such Change in
Control and of the repurchase right arising as a result thereof. To exercise the
repurchase  right,  a Holder of Notes  must  deliver  on or before the fifth day
prior to the Repurchase  Date  irrevocable  written notice to the Trustee of the
Holder's  exercise of such right,  together with the Notes with respect to which
the right is being exercised.

     A Change in Control shall be deemed to have occurred at such time after the
original issuance of the Notes as there shall occur:

     (i) the  acquisition  by any Person of  beneficial  ownership,  directly or
indirectly,  through a  purchase,  merger or other  acquisition  transaction  or
series of transactions, of shares of capital stock of the Company entitling such
Person  to  exercise  50% or more of the  total  voting  power of all  shares of
capital  stock  of the  Company  entitled  to vote  generally  in  elections  of
directors,  other  than any such  acquisition  by the  Company  or any  employee
benefit plan of the Company; or

     (ii) any  consolidation  or  merger of the  Company  with or into any other
Person,  any merger of  another  Person  into the  Company,  or any  conveyance,
transfer,  sale, lease or other  disposition of all or substantially  all of the
properties  and assets of the Company to another Person (other than (a) any such
transaction  (x)  which  does not  result in any  reclassification,  conversion,
exchange or cancellation of outstanding  shares of Common Stock and (y) pursuant
to which holders of Common Stock  immediately prior to such transaction have the
entitlement to exercise, directly or indirectly, 50% or more of the total voting
power of all shares of capital stock  entitled to vote generally in the election
of  directors  of the  continuing  or surviving  person  immediately  after such
transaction  and  (b)  any  merger  which  is  effected  solely  to  change  the
jurisdiction of incorporation of the Company and results in a  reclassification,
conversion or exchange of outstanding  shares of Common Stock into solely shares
of common stock);

     PROVIDED,  HOWEVER,  that a Change in  Control  shall not be deemed to have
occurred if the sum of the  closing bid price per share of the Common  Stock for
any five  Trading Days within the period of 10  consecutive  Trading Days ending
immediately  after the later of the date of the Change in Control or the date of
the public  announcement  of the  Change in Control  (in the case of a Change in
Control  under  clause  (i)  above) or ending  immediately  before the Change in
Control  (in the case of a Change in Control  under  clause (ii) above) plus the
fair market value per share (as determined by the Board of

                                     -28-

<PAGE>

Directors in good faith, which  determination  shall be conclusive) of any Other
Stock or other  property  then held in escrow for the  benefit of the Holders as
described above under "--Conversion  Rights",  shall equal or exceed 105% of the
Conversion  Price  of the  Notes  in  effect  on  each  such  Trading  Day.  The
"Conversion   Price"  is  equal  to  $1,000  divided  by  the  Conversion  Rate.
"Beneficial owner" shall be determined in accordance with Rule 13d-3 promulgated
by the  Commission  under the Exchange Act.  "Person"  includes any syndicate or
group  which  would be deemed to be a  "person"  under  Section 13 (d)(3) of the
Exchange Act.

     The Company  may, to the extent  permitted by  applicable  law, at any time
purchase  Notes in the open  market  or by  tender  at any  price or by  private
agreement. Subject to certain limitations imposed by the Purchase Agreement with
the  Purchasers,  any Note so purchased by the Company may be reissued or resold
or may, at the Company's option, be surrendered to the Trustee for cancellation.
Any Notes  surrendered  as  aforesaid  may not be reissued or resold and will be
cancelled promptly.

     The foregoing  provisions would not necessarily afford Holders of the Notes
protection in the event of highly leveraged or other transactions  involving the
Company that may adversely affect Holders.

MERGERS AND SALES OF ASSETS BY THE COMPANY

     The Company shall not  consolidate  with or merge into any other Person or,
directly or indirectly, convey, transfer, sell or lease all or substantially all
of its properties and assets to any Person, and the Company shall not permit any
Person to consolidate with or merge into the Company or convey,  transfer,  sell
or lease all or  substantially  all of its properties and assets to the Company,
unless (a) the  Person  formed by such  consolidation  or into or with which the
Company  is merged  or the  Person to which  the  properties  and  assets of the
Company are so conveyed, transferred, sold or leased, is a corporation,  limited
liability company, partnership or trust organized and existing under the laws of
the United  States,  any State  thereof or the  District of  Columbia  and shall
expressly assume the due and punctual  payment of the principal of, premium,  if
any, and interest on the Notes and the performance of the other covenants of the
Company under the Indenture  and shall have  provided for  conversion  rights as
described above under "--Conversion Rights", (b) immediately after giving effect
to such transaction,  no Event of Default,  and no event which,  after notice or
lapse of time or both, would become an Event of Default, shall have occurred and
be  continuing  and (c) the  Company  shall  have  provided  to the  Trustee  an
Officer's Certificate and Opinion of Counsel as provided in the Indenture.

EVENTS OF DEFAULT

     The following will be Events of Default under the Indenture: (a) failure to
pay  principal  or premium,  if any,  on any Note when due,  whether or not such
payment is prohibited by the  subordination  provisions  of the  Indenture,  (b)
failure  to pay any  interest  on any Note  when  due,  continuing  for 30 days,
whether or not such payment is prohibited by the subordination provisions of the
Indenture; (c) default in the Company's obligation to provide notice of a Change
in Control; (d) failure to perform any other covenant or warranty of the Company
in the Indenture,  continuing for 60 days after written notice to the Company by
the  Trustee or the  Holders of at least 10% in  aggregate  principal  amount of
Outstanding Notes; (e) failure to pay when due the principal of, or acceleration
of, any  indebtedness  for money borrowed by the Company in excess of $5,000,000
if such  indebtedness is not discharged,  or such  acceleration is not annulled,
within 30 days after written notice to the Company by the Trustee or the Holders
of at least 10% in aggregate  principal  amount of  Outstanding  Notes;  and (f)
certain  events of  bankruptcy,  insolvency  or  reorganization  of the Company.
Subject to the provisions of the Indenture relating to the duties of the Trustee
in case an Event of Default shall occur and be  continuing,  the Trustee will be
under no  obligation to exercise any of its rights or powers under the Indenture
at the request or  direction of any of the  Holders,  unless such Holders  shall
have offered to the Trustee reasonable indemnity. Subject to such provisions for
the  indemnification  of the  Trustee,  the Holders of a majority  in  aggregate
principal  amount of the  Outstanding  Notes  will have the right to direct  the
time,  method and place of conducting any proceeding for any remedy available to
the Trustee or exercising any trust or power conferred on the Trustee.

     If an Event of Default (other than an Event of Default  specified in clause
(f) above)  occurs and is  continuing,  either the Trustee or the Holders of not
less  than 25% in  aggregate  principal  amount  of the  Outstanding  Notes  may
accelerate the maturity of all Notes. If an Event of Default specified in clause
(f) occurs and is continuing,  the principal and any accrued  interest on all of
the Notes then Outstanding  shall IPSO FACTO become due and payable  immediately
without any declaration or other Act on the part of the Trustee or any Holder.

                                     -29-

<PAGE>

     At any time after a declaration of acceleration  has been made but before a
judgment  or decree  based on  acceleration  has been  issued,  the Holders of a
majority in aggregate  principal amount of Outstanding  Notes may, under certain
circumstances as set forth in the Indenture, rescind and annul such acceleration
if all Events of Default, other than the nonpayment of accelerated principal and
interest,  have  been  cured  or  waived  as  provided  in  the  Indenture.  For
information as to waiver of defaults, See "--Modification and Waiver."

     No Holder of any Note will have any right to institute any proceeding  with
respect to the Indenture or for any remedy thereunder,  unless such Holder shall
have  previously  given to the Trustee  written notice of a continuing  Event of
Default  and  unless  also the  Holders of at least 25% in  aggregate  principal
amount of the  Outstanding  Notes shall have made written  request,  and offered
reasonable  indemnity,  to the Trustee to institute such  proceeding as trustee,
and the  Trustee  shall not have  received  from the  Holders of a  majority  in
aggregate  principal  amount of the Outstanding  Notes a direction  inconsistent
with such request and shall have failed to institute such  proceeding  within 60
days. However, such limitations do not apply to a suit instituted by a Holder of
a Note for the enforcement of payment of the principal of,  premium,  if any, or
interest on such Note or after the respective  due dates  expressed in such Note
or of the right to convert such Note in accordance with the Indenture.

     The Company will be required to furnish to the Trustee annually a statement
as to the  performance  by the Company of certain of its  obligations  under the
Indenture and as to any default in such performance.

MODIFICATION AND WAIVER

     Modifications  and amendments of the Indenture may be made with the written
consent of the  Holders of not less than a majority in  principal  amount of the
Notes at the time Outstanding.  However,  no such modification or amendment may,
without the consent of the Holder of each Outstanding Note affected thereby, (a)
change the Stated  Maturity of the principal of, or any  installment of interest
on, any Note,  (b) reduce the  principal  amount of, or the premium,  if any, or
rate of interest  on, any Note,  (c) modify the  provisions  with respect to the
repurchase  right of the Holders in a manner adverse to the Holders,  (d) change
the place or currency of payment of principal of,  premium,  if any, or interest
on any Note, (e) impair the right to institute  suit for the  enforcement of any
payment on or with respect to, or the right to convert,  any Note, (f) except as
otherwise  permitted or  contemplated  by provisions  concerning  consolidation,
merger,  conveyance,  transfer, sale or lease of all or substantially all of the
property and assets of the Company or  distributions  of Other Stock,  adversely
affect the right to convert Notes, (g) modify the subordination  provisions in a
manner  adverse  to the  Holders  of the  Notes,  (h)  reduce  the  above-stated
percentage of aggregate  principal  amount of  Outstanding  Notes  necessary for
waiver of compliance  with certain  provisions of the Indenture or for waiver of
certain  defaults  or (i)  modify  the  obligation  of the  Company  to  deliver
information required under Rule 144A to permit resales of Notes and Common Stock
issuable upon  conversion  thereof in the event the Company ceases to be subject
to certain reporting requirements under the United States securities laws.

     The  Holders of a majority in  aggregate  principal  amount of  Outstanding
Notes may waive compliance by the Company with certain restrictive provisions of
the Indenture.  The Holders of a majority in aggregate  principal  amount of the
Outstanding Notes may waive any past default by the Company under the Indenture,
except a default in the payment of principal,  premium, if any, or interest or a
default  in any  covenant  or  provision  which  under the  Indenture  cannot be
modified or amended without the consent of each Holder of Outstanding Notes.

NOTICES

     Notice to Holders of the Notes  will be given by mail to the  addresses  of
such  Holders as they appear in the  Security  Register.  Such  notices  will be
deemed to have been given on the date of mailing of the notice.

     Notice of a  redemption  of Notes will be given at least once not less than
30 nor more than 60 days prior to the  Redemption  Date (which  notice  shall be
irrevocable) and will specify the Redemption Date and the Redemption Price.

PAYMENT OF STAMP AND OTHER TAXES

     The Company shall pay all stamp and other duties, if any, which may be
imposed by the United States or any political subdivision thereof or taxing
authority thereof or therein with respect to the issuance of the Notes. The
Company

                                     -30-

<PAGE>

will  not be  required  to make any  payment  with  respect  to any  other  tax,
assessment or  governmental  charge  imposed by any  government or any political
subdivision thereof or taxing authority therein.

GOVERNING LAW

     The Indenture and the Notes will be governed by and construed in accordance
with the laws of the State of New York.

THE TRUSTEE

     State Street Bank and Trust Company is the Trustee for the Notes.


DESCRIPTION OF CAPITAL STOCK

     The Company's  authorized  capital stock  consists of 50,000,000  shares of
Common Stock,  no par value,  and 500,000  shares of preferred  stock,  $.01 par
value ("PREFERRED STOCK").

COMMON STOCK

     As of March  31,  1997,  there  were  26,493,367  shares  of  Common  Stock
outstanding.  Holders of Common  Stock are  entitled  to one vote for each share
held of record on all matters submitted to a vote of stockholders.  Accordingly,
holders of a  majority  of the shares of Common  Stock  entitled  to vote in any
election of Directors  may elect all of the  Directors  standing  for  election.
Subject  to  preferential  dividend  rights  with  respect  to  any  outstanding
Preferred  Stock,  holders of Common Stock are entitled to receive  ratably such
dividends,  if any, as may be declared  by the Board of  Directors  out of funds
legally available therefor.  Upon liquidation,  dissolution or winding up of the
Company,  holders of Common Stock are entitled to share ratably in the assets of
the Company legally  available for  distribution to the holders of Common Stock,
and subject to any prior rights of any outstanding  Preferred Stock.  Holders of
Common Stock have no cumulative voting rights nor any preemptive,  subscription,
redemption or conversion rights. All outstanding shares of Common Stock are, and
the shares  issuable upon the  conversion  of the Notes offered  hereby will be,
when issued and paid for,  validly issued,  fully paid and  non-assessable.  The
rights,  preferences  and  privileges of holders of Common Stock are subject to,
and may be  adversely  affected  by, the rights of the  holders of shares of any
series of  Preferred  Stock  which the Company  may  designate  and issue in the
future.

PREFERRED STOCK

     The Board of Directors is  authorized,  without  stockholder  approval,  to
issue the Preferred Stock in one or more series,  with such rights,  preferences
and  qualifications  as the Board of Directors may in its discretion  determine.
The Company  currently has no plans to issue any shares of Preferred  Stock.  If
the Company  issues  Preferred  Stock in the future,  the terms of the Preferred
Stock  may  include,  among  other  things,   extraordinary  voting,   dividend,
redemption or conversion  rights which could discourage  acquisition bids of the
Company and adversely affect the holders of Common Stock.  Massachusetts Law and
Certain Charter and By-Law Provisions Certain Anti-Takeover Provisions

MASSACHUSETTS LAW AND CERTAIN CHARTER AND BY-LAW PROVISIONS

CERTAIN ANTI-TAKEOVER PROVISIONS

     The  Company  is  subject  to  the   provisions  of  Chapter  110F  of  the
Massachusetts  General  Laws,  an  anti-takeover  law. In general,  this statute
prohibits  a  Massachusetts  corporation  with more than 200  stockholders  from
engaging in a "business combination" with "interested stockholders" for a period
of three years after the date of the  transaction in which the person becomes an
interested  stockholder,  unless either (i) the Board of Directors  approves the
business  combination or the  transaction  in which the  interested  stockholder
became  an  interested   stockholder  prior  to  such  stockholder  becoming  an
interested  stockholder,  (ii) the  interested  stockholder  acquires 90% of the
outstanding  voting stock of the corporation  (excluding  shares held by certain
affiliates of the corporation) at the time the stockholder becomes an interested
stockholder  or (iii) the business  combination is approved by both the Board of
Directors at a meeting or by written  consent and holders of  two-thirds  of the
outstanding  voting  stock  of the  corporation  (excluding  shares  held by the
interested  stockholder) at a meeting and not by written consent. An "interested
stockholder" is a person who, together with affiliates and associates,  owns (or
at  any  time  within  the  prior  three  years  did  own)  5% or  more  of  the
corporation's voting stock. A "business  combination" includes a merger, a stock
or asset sale, and certain other specified transactions resulting in a financial
benefit to the

                                     -31-

<PAGE>

stockholder.  In addition,  Massachusetts  General Laws Chapter  110D,  entitled
"Regulation  of Control  Share  Acquisition,"  provides,  in  general,  that any
stockholder of a corporation subject to this statute who acquires 20% or more of
the outstanding voting stock of a corporation may not vote such stock unless the
stockholders  of the  corporation  so  authorize at a meeting and not by written
consent.

     Massachusetts General Laws Chapter 156B, Section 50A, requires that, unless
an express  election is made, a publicly held  Massachusetts  corporation have a
classified  Board of Directors  consisting  of three  classes as nearly equal in
size as possible. The Company is subject to the provisions of Section 50A.

     Certain  of  the   provisions  of  the  Company's   Restated   Articles  of
Organization  discussed  above and the  Massachusetts  Business  Corporation Law
would  make  more  difficult  or  could   discourage  a  proxy  contest  or  the
acquisitions  of control  by a holder of a  substantial  block of the  Company's
stock or the removal of the incumbent Board of Directors and could also have the
effect of  discouraging  a third party from making a tender  offer or  otherwise
attempting to obtain  control of the Company,  even though such an attempt might
be beneficial to the Company and its stockholders.  In addition, because certain
provisions  of the  Restated  Articles  of  Organization  and the  Massachusetts
Business  Corporation  Law are  designed to  discourage  accumulations  of large
blocks of the  Company's  stock by  purchasers  whose  objective is to have such
stock  repurchased by the Company at a premium,  such  provisions  could tend to
reduce the temporary  fluctuations  in the market price of the  Company's  stock
which  are  caused by such  accumulations.  Accordingly,  stockholders  could be
deprived of certain  opportunities  to sell their stock at a temporarily  higher
market price.

     Reference is made to the full text of the foregoing statutes, the Company's
Restated Articles of Organization and the Company's Amended and Restated By-laws
for their entire terms, and the partial summary contained herein is not intended
to be complete.

ELIMINATION OF MONETARY LIABILITY FOR OFFICERS AND DIRECTORS

     The Company's  Restated Articles of Organization  also incorporate  certain
provisions  permitted  under the  Massachusetts  General  Laws  relating  to the
liability of  Directors.  The  provisions  eliminate a Director's  liability for
monetary  damages for a breach of fiduciary duty,  including  gross  negligence,
except in circumstances involving certain wrongful acts, such as the breach of a
Director's  duty of  loyalty  or acts or  omissions  not in good  faith or which
involve intentional misconduct or a knowing violation of law or authorization of
distributions in violation of the Restated  Articles of Organization or of loans
to officers or Directors of the Company,  but do not eliminate a Director's duty
of care. Moreover,  the provisions do not apply to claims against a Director for
violations of certain laws,  including  federal  securities  laws. The Company's
Restated  Articles of Organization and Amended and Restated By-Laws also contain
provisions to indemnify the  Directors,  officers,  employees or other agents to
the fullest  extent  permitted by the  Massachusetts  General Laws.  The Company
believes  that these  provisions  will  assist  the  Company  in  attracting  or
retaining qualified individuals to serve as Directors or officers.

INDEMNIFICATION OF OFFICERS AND DIRECTORS

     The Company's  Restated Articles of Organization also contain provisions to
indemnify  its  Directors,  officers,  employees  or other agents to the fullest
extent  permitted by the  Massachusetts  General Laws. These provisions may have
the practical effect in certain cases of eliminating the ability of stockholders
to collect  monetary  damages from  Directors.  The Company  believes that these
provisions  will  assist  the  Company  in  attracting  or  retaining  qualified
individuals to serve as Directors or officers.

TRANSFER AGENT AND REGISTRAR

     The  Transfer  Agent and  Registrar  for the Common Stock of the Company is
Boston EquiServe L.P.

                          UNITED STATES TAXATION

     The  following is a summary of certain  United  States  federal  income and
estate tax considerations relating to the purchase, ownership and disposition of
the Notes and of Common  Stock into which  Notes may be  converted  but does not
purport  to be a  complete  analysis  of all the  potential  tax  considerations
relating  thereto.  This  summary  is based on laws,  regulations,  rulings  and
decisions  now in effect  (or,  in the case of certain  United  States  Treasury
Regulations  ("TREASURY  REGULATIONS"),  now in proposed form), all of which are
subject to change. This summary deals only with holders that will hold Notes and
Common Stock into which Notes may be converted as "capital  assets"  (within the
meaning of Section  1221 of the Internal  Revenue Code of 1986,  as amended (the
"CODE")) and does not address tax  considerations  applicable to investors  that
may be subject to special tax rules,  such as banks,  tax-exempt  organizations,
insurance companies, dealers in securities or currencies, persons that will hold
Notes  as  a  position  in  a  hedging  transaction,   straddle  or  "conversion
transaction"  for tax  purposes,  or persons that have a  "functional  currency"
other  than the U.S.  dollar.  This  summary  discusses  the tax  considerations
applicable  to the initial  purchasers  of the Notes who  purchase  the Notes at
their "issue price," as defined in Section 1273 of the Code and does not discuss
the tax  considerations  applicable to subsequent  purchasers of the Notes.  The
Company has not sought any ruling from the Internal Revenue Service with respect
to the statements made and the conclusions reached in the following summary, and
there can be no assurance that the Internal Revenue Service will agree with such
statements and conclusions.  INVESTORS  CONSIDERING THE PURCHASE OF NOTES SHOULD
CONSULT  THEIR OWN TAX ADVISORS  WITH RESPECT TO THE  APPLICATION  OF THE UNITED
STATES FEDERAL INCOME AND ESTATE TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL
AS ANY TAX  CONSEQUENCES  ARISING UNDER THE LAWS OF ANY STATE,  LOCAL OR FOREIGN
TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY.

UNITED STATES HOLDERS

     As used herein, the term "United States Holder" means a beneficial owner of
a Note or Common Stock that for United States federal income tax purposes is (i)
a  citizen  or  resident  of the  United  States,  (ii)  treated  as a  domestic
corporation  or domestic  partnership,  or (iii) an estate or trust other than a
"foreign  estate" or "foreign  trust" as defined in Section  7701(a)(31)  of the
Code.

PAYMENT OF INTEREST

     Interest on a Note  generally  will be includable in the income of a United
States  Holder as  ordinary  income at the time such  interest  is  received  or
accrued, in accordance with such Holder's method of accounting for United States
federal income tax purposes.

SALE, EXCHANGE OR REDEMPTION OF THE NOTES

     Upon the sale,  exchange or  redemption  of a Note, a United  States Holder
generally  will recognize  capital gain or loss equal to the difference  between
(i) the  amount  of cash  proceeds  and the fair  market  value of any  property
received on the sale,  exchange or redemption  (except to the extent such amount
is attributable to accrued interest income, which is taxable as ordinary income)
and (ii) such Holder's  adjusted tax basis in the Note. A United States Holder's
adjusted tax basis in a Note  generally  will equal the cost of the Note to such
Holder,  less any principal payments received by such Holder.  Such capital gain
or loss will be  long-term  capital gain or loss if the United  States  Holder's
holding  period in the Note is more than one year at the time of sale,  exchange
or redemption, and otherwise will be short-term capital gain or loss.

CONVERSION OF THE NOTES

     A United States  Holder  generally  will not recognize any income,  gain or
loss upon  conversion  of a Note into Common  Stock  except with respect to cash
received in lieu of a  fractional  Share of Common  Stock.  Such  United  States
Holder's tax basis in the Common Stock  received on conversion of a Note will be
the  same as  such  Holder's  adjusted  tax  basis  in the  Note at the  time of
conversion (reduced by any basis allocable to a fractional share interest),  and
the holding  period for the Common Stock  received on conversion  will generally
include the holding period of the Note converted.

                                     -33-

<PAGE>
     Cash received in lieu of a fractional share of Common Stock upon conversion
will be treated  as a payment in  exchange  for the  fractional  share of Common
Stock. Accordingly,  the receipt of cash in lieu of a fractional share of Common
Stock  generally will result in capital gain or loss (measured by the difference
between  the cash  received  for the  fractional  share  and the  United  States
Holder's adjusted tax basis in the fractional share).

DIVIDENDS

     Distributions  paid on the Common Stock generally will be includable in the
income of the  United  States  Holder as  ordinary  income to the  extent of the
Company's  current or accumulated  earnings and profits.  Distributions  paid on
shares  of  Common  Stock  that  are in  excess  of  the  Company's  current  or
accumulated earnings and profits will generally be treated, first, as a tax-free
return of capital to the extent of the United States Holder's adjusted tax basis
in its shares, and then as capital gain.

     United  States  Holders  should  also note that,  as a  consequence  of the
conversion feature inherent in the Notes, under Section 305 of the Code, certain
events, such as a modification to the conversion price of the Notes to take into
account certain dividends,  if any, distributed on the Common Stock, could cause
a Holder of Notes to realize  ordinary  income in respect of the Notes without a
corresponding receipt of cash or other property.

SALE OF COMMON STOCK

     Upon the sale or exchange of Common Stock, a United States Holder generally
will  recognize  capital  gain or loss equal to the  difference  between (i) the
amount of cash and the fair market  value of any property  received  pursuant to
the sale or exchange and (ii) such United States Holder's  adjusted tax basis in
the Common  Stock.  Such capital gain or loss will be long-term  capital gain or
loss  dependent  upon the United States  Holder's  holding  period in the Common
Stock at the time of the sale or exchange.  A United States  Holder's  basis and
holding period in Common Stock received upon conversion of a Note are determined
as discussed above under "--Conversion of the Notes."

INFORMATION REPORTING AND BACKUP WITHHOLDING TAX

     In general,  information  reporting  requirements will apply to payments of
principal,  premium,  if any, and  interest on a Note,  payments of dividends on
Common Stock, payments of the proceeds of the sale of a Note and payments of the
proceeds  of the sale of Common  Stock to  certain  noncorporate  United  States
Holders,  and a 31% backup  withholding  tax may apply to such  payments  if the
United  States  Holder  (i) fails to furnish or  certify  his  correct  taxpayer
identification  number to the payor in the manner required,  (ii) is notified by
the Internal  Revenue  Service (the "IRS") that he has failed to report payments
of interest and dividends properly, or (iii) under certain circumstances,  fails
to certify that he has not been notified by the IRS that he is subject to backup
withholding  for failure to report interest and dividend  payments.  Any amounts
withheld  under the backup  withholding  rules from a payment to a United States
Holder will be allowed as a credit  against such Holder's  United States federal
income tax and may entitle the United States  Holder to a refund,  provided that
the required information is furnished to the IRS.


NON-UNITED STATES HOLDERS

     As used herein,  the term  "Non-United  States Holder" means any beneficial
owner of a Note or Common Stock that is not a United States Holder.

PAYMENT OF INTEREST

     Payment of  interest  on a Note by the  Company  or any  paying  agent to a
Non-United States Holder will quality for the "portfolio interest exemption" and
therefore will not be subject to United States federal income tax or withholding
tax,  provided that such interest  income is not  effectively  connected  with a
United  States trade or business of the Non- United  States  Holder and provided
that the Non-United  States Holder (i) does not actually or  constructively  own
10% or more of the combined  voting power of all classes of stock of the Company
entitled to vote, (ii) is not a controlled  foreign  corporation  related to the
Company actually or constructively through stock ownership,  (iii) is not a bank
receiving interest on a loan entered into in the ordinary course of business and
(iv) either (a) provides a Form W-8 (or suitable  substitute  form) signed under
penalties of perjury that  includes its name and address and certifies as to its
non-United States status in compliance

                                     -34-
<PAGE>

with applicable law and regulations,  or (b) deposits the Note with a securities
clearing  organization,  bank or  financial  institution  that holds  customers'
securities  in the ordinary  course of its trade or business and which holds the
Note and  provides a statement  to the Company or its agent under  penalties  of
perjury in which it  certifies  that such a Form W-8 (or a suitable  substitute)
has  been  received  by it from  the  Non-United  States  Holder  or  qualifying
intermediary and furnishes the Company or its agent with a copy thereof.

     Recently proposed Treasury  Regulations (the "PROPOSED  REGULATIONS") would
provide  alternative  methods  for  satisfying  the  certification   requirement
described in clause (iv) above. The Proposed  Regulations also would require, in
the case of Notes  held by a  foreign  partnership,  that (a) the  certification
described  in clause (iv) above be provided by the  partners  rather than by the
foreign  partnership  and  (b)  the  partnership  provide  certain  information,
including a United States taxpayer  identification  number. A look-through  rule
would apply in the case of tiered  partnerships.  The Proposed Regulations would
be  effective  for  payments  made  after  December  31,  1997.  There can be no
assurance that the Proposed  Regulations will be adopted or as to the provisions
that they will include if and when adopted in temporary or final form.

     Except to the extent  otherwise  provided  under an  applicable  treaty,  a
Non-United  States Holder generally will be taxed in the same manner as a United
States  Holder with  respect to interest  on a Note if such  interest  income is
effectively  connected  with a United States trade or business of the Non-United
States Holder. Effectively connected interest received by a corporate Non-United
States Holder may also, under certain circumstances, be subject to an additional
"branch  profits tax" at a 30% rate (or, if  applicable,  a lower treaty  rate).
Even  though such  effectively  connected  interest is subject to United  States
federal  income  tax,  and may be subject to the branch  profits  tax, it is not
subject to withholding tax if the Holder delivers IRS Form 4224 to the payor.

     Interest  income of a  Non-United  States  Holder  that is not  effectively
connected  with a United  States trade or business and that does not qualify for
the portfolio interest exemption  described above will generally be subject to a
withholding tax at a 30% rate (or, if applicable, a lower treaty rate).

SALE, EXCHANGE OR REDEMPTION OF THE NOTES

     A  Non-United  States  Holder of a Note will  generally  not be  subject to
United States federal income tax or withholding  tax on any gain realized on the
sale, exchange or redemption of a Note (including the receipt of cash in lieu of
fractional shares upon conversion of a Note to Common Stock, unless (1) the gain
is  effectively  connected  with  a  United  States  trade  or  business  of the
Non-United  States Holder,  (2) in the case of a Non-United States Holder who is
an  individual,  such  Holder is present  in the  United  States for a period or
periods aggregating 183 days or more during the taxable year of the disposition,
and either such Holder has a "tax home" in the United States or the  disposition
is attributable to an office or other fixed place of business maintained by such
Holder in the United  States,  (3) the Holder is subject to tax  pursuant to the
provisions of the Code applicable to certain United States  expatriates,  or (4)
the Company is a United States real property holding corporation (see discussion
under "United States Foreign Investment in Real Property Tax Act" below).

CONVERSION OF THE NOTES

     In general,  no United States federal income tax or withholding tax will be
imposed upon the  conversion of a Note into Common Stock by a Non-United  States
Holder except with respect to the receipt of cash in lieu of  fractional  shares
by Non-United States Holders upon conversion of a Note where any one of the four
exceptions described above under "Non-United States Holders---Sale,  Exchange or
Redemption of the Notes" is applicable.

SALE OR EXCHANGE OF COMMON STOCK

     A Non-United  States Holder  generally will not be subject to United States
federal  income tax or  withholding  tax on the sale or exchange of Common Stock
unless any one of the four exceptions  described above under "Non-United  States
Holders--Sale, Exchange or Redemption of the Notes" is applicable.

DIVIDENDS

     Dividends  paid (or deemed paid, as described  above under  "United  States
Holders--Dividends")  on Common  Stock to a  Non-United  States  Holder  will be
subject  to United  States  federal  withholding  tax at 30% rate (or lower rate
provided

                                     -35-

<PAGE>

under an applicable  income tax treaty),  unless the  dividends are  effectively
connected  with the conduct of a trade or business in the United States (and are
attributable to a United States permanent  establishment  of such Holder,  if an
applicable  income tax treaty so  requires  as a  condition  for the  Non-United
States  Holder to be subject to United States income taxes on a net income basis
in respect of such dividends).  Except to the extent otherwise provided under an
applicable  tax treaty,  a  Non-United  States  Holder will be taxed in the same
manner as a United  States  Holder on  dividends  paid (or deemed paid) that are
effectively  connected  with the  conduct of a trade or  business  in the United
States by the Non-United  States Holder.  If such Non-United  States Holder is a
foreign  corporation,  it may also be subject to a United States branch  profits
tax on such effectively connected income at a 30% rate or such lower rate as may
be specified by an applicable  income tax treaty.  Even though such  effectively
connected  dividends are subject to income tax, and may be subject to the branch
profits  tax,  they will not be subject  to  withholding  tax if the  Non-United
States Holder timely delivers IRS Form 4224 to the payor.

     Under  current  Treasury  Regulations,  dividends  paid to an  address in a
foreign  country are presumed to be paid to a resident of that  country  (unless
the payor has knowledge to the contrary) for purposes of the  withholding  rules
discussed below and, under the current  interpretation of Treasury  Regulations,
for purposes of determining the  applicability  of a tax treaty rate.  Under the
Proposed  Regulations,  however,  a Non-United States Holder of Common Stock who
wishes to claim the  benefit of an  applicable  treaty rate would be required to
satisfy applicable certification  requirements.  In addition, under the Proposed
Regulations,  in the case of Common Stock held by a foreign  partnership (x) the
certification  requirement  would  generally  be applied to the  partners of the
partnership  and (y) the  partnership  would  be  required  to  provide  certain
information,  including a United  States  taxpayer  identification  number.  The
Proposed Regulations also provide look-through rules for tiered partnerships. It
is not  certain  whether,  or in what form,  the  Proposed  Regulations  will be
adopted or the provisions  they will include if and when adopted in temporary or
final form.

DEATH OF A NON-UNITED STATES HOLDER

     A Note held by an individual who is not a citizen or resident of the United
States  at the time of death  will not be  includable  in the  decedent's  gross
estate for United  States  estate tax  purposes,  provided  that such  Holder or
beneficial owner did not at the time of death actually or constructively own 10%
or more of the  combined  voting  power of all  classes of stock of the  Company
entitled to vote, and provided that, at the time of death, payments with respect
to such Note would not have been effectively  connected with the conduct by such
Non-United States Holder of a trade or business within the United States.

     Common Stock actually or beneficially held by a Non-United States Holder at
the time of his or her death  (or  previously  transferred  subject  to  certain
retained  rights or powers) will be subject to United States  federal estate tax
unless otherwise provided by an applicable estate tax treaty.

INFORMATION REPORTING AND BACKUP WITHHOLDING TAX

     Under  current  law,  information  reporting  on IRS Form  1099 and  backup
withholding  will not apply to payments on a Note to a Non-United  States Holder
if the statement  described in "Non-United States  Holders--Payment of Interest"
is duly  provided by such Holder,  provided  that the payor does not have actual
knowledge  that the Holder is a United  States  person.  The Company or a paying
agent, however, may report (on IRS Form 1042-S) payments of interest on Notes.

     Information  reporting  requirements  and backup  withholding  tax will not
apply to any payment of the proceeds of the sale of a Note or any payment of the
proceeds of the sale of Common  Stock  effected  outside the United  States by a
foreign  office of a "broker" (as defined in applicable  Treasury  Regulations),
unless such broker (i) is a United  States  person,  (ii) derives 50% or more of
its gross income for certain  periods from the conduct of a trade or business in
the United States or (iii) is a controlled foreign  corporation as to the United
States.  Payment of the  proceeds of any such sale  effected  outside the United
States by a foreign office of any broker that is described in (i), (ii) or (iii)
of the  preceding  sentence will not be subject to backup  withholding  tax, but
will be subject to information  reporting  requirements,  unless such broker has
documentary  evidence in its records that the  beneficial  owner is a Non-United
States  Holder and certain other  conditions  are met, or the  beneficial  owner
otherwise establishes an exemption.  Payment of the proceeds of any such sale to
or through  the  United  States  office of a broker is  subject  to  information
reporting and backup  withholding  requirements,  unless the beneficial owner of

     If paid to an address outside the United States,  dividends on Common Stock
held  by a  Non-United  States  Holder  will  generally  not be  subject  to the
information  reporting  and backup  withholding  requirements  described in this
section, provided the payor does not have definite knowledge that the payee is a
United    States   person   (see    discussion    under    "Non-United    States
Holders--Dividends" with respect to the Proposed Regulations).

     These backup  withholding and information  reporting rules are under review
by the United States  Department of the Treasury,  and their  application to the
Notes and Common Stock could be changed prospectively by future regulations.

UNITED STATES FOREIGN INVESTMENT IN REAL PROPERTY TAX ACT

     Under the Foreign  Investment  in Real  Property  Tax Act  ("FIRPTA"),  any
person who  acquires a "United  States real  property  interest"  (as  described
below) from a foreign  person must deduct and withhold a tax equal to 10% of the
amount  realized by the foreign  transferor.  In addition,  a foreign person who
disposes of a United  States real  property  interest  generally  is required to
recognize  gain or loss that is subject to United States  federal  income tax. A
"United States real property  interest"  generally  includes any interest (other
than an interest solely as a creditor) in a United States  corporation unless it
is established  under specific  procedures  that the corporation is not (and was
not for the prior  five-year  period) a "United  States  real  property  holding
corporation."  However,  stock in a United States corporation generally will not
be treated as a United States real property  interest if, at any time during the
calendar year, that class of stock of the corporation is regularly  traded on an
established securities market and the relevant Holder holds five percent or less
of such class of stock (the "REGULARLY TRADED  EXEMPTION").  The Company has not
been,  is not, and does not  anticipate  becoming a United  States real property
holding  corporation.  In the unlikely event that it is not established that the
Company is not a United States real property holding  corporation,  then, unless
an  exemption  applies,  both the Common Stock and the Notes would be treated as
United States real property interests and the disposition of either Common Stock
or Notes by a  Non-United  States  Holder  would be  subject  to FIRPTA  tax and
withholding.
