Item 5.  Other Events.

         On  December  29,  1995 the  Registrant  executed  a Note  and  Warrant
Purchase, Paying and Conversion/Exercise Agency Agreement (the "Note Agreement")
with  Banca  del  Gottardo  ("Gottardo").  Pursuant  to the Note  Agreement  the
Registrant  issued $7.5 million of its 8%  Convertible  Subordinated  Notes (the
"Notes") due December  31, 2000 and warrants to purchase  300,000  shares of the
Registrant's  common stock,  $.01 par value (the "Common  Stock") (the "Gottardo
Warrants").  The  conversion  price of the Notes and the  exercise  price of the
Gottardo  Warrants will be  established  on March 29, 1996 and will be the lower
of:  (a)  $4.75  per  shares,  (b) the  average  of the  closing  prices  of the
Registrant's  Common Stock during the period from March 14 to March 29, 1996, or
(c) 120% of the average of the closing prices of the  Registrant's  Common Stock
during the period from December 19 to December 29, 1995.

         The Registrant used the net proceeds  ($7,000,000) from the sale of the
Notes to repay  the  outstanding  12.5%  Series B Notes  due to  Nomura  Holding
America,   Inc.  ($4,500,000)  and  for  general  working  capital  ($2,500,000)
including payment of outstanding trade payables.

         In connection  with the issuance of the Notes the Registrant  issued an
additional  Warrant to purchase 200,000 shares of the Registrant's  Common Stock
(the "Additional Warrant"). The exercise price for the Additional Warrant is the
same price as for the Gottardo Warrants.

                  Warrants represented by the Global Warrant or interest therein
                  may be offered,  sold or transferred into the United States or

                  certification,  in the form  attached  hereto as Annex J, that
                  the beneficial  owners of the Notes or Warrants either (i) are
                  not  United  States  persons  or  U.S.  persons  or  (ii)  are

                  United  States.  Any  certificates   provided  by  a  clearing
                  organization must be based on statements provided to it by its
                  members.  A beneficial  owner of Notes must exchange its share
                  of the Global Note for  definitive  Notes before such Notes or
                  interests  therein may be  transferred or as regards the Notes

                  Warrant in definitive form, and (ii) to issue definitive Notes
                  and  Warrants  within a  reasonable  time after the end of the
                  Restricted  Period  (for  this  purpose,  a  temporary  global

                  appoint any  institutions  as paying agent without the consent

         of Coupons and/or Notes or Warrants will remain in safekeeping at Banca
         del Gottardo during the statutory limitation.

         If any sum due from the Company in favour of the Paying Agent has to be

         exchange  used for such purpose to convert the sum in question from the
         first  currency  into the second  currency and (b) the rate or rates of

         whole or in part of any such order, judgment, claim or proof.

         from the  other  obligations  contained  herein,  shall  give rise to a
         separate and independent cause of action and shall apply,  irrespective
         of any waiver granted by Banca del Gottardo from time to time and shall
         continue in full force and effect notwithstanding any judgment or order
         for a liquidated sum or sums in

         respect of amounts due  hereunder or under any such  judgment or order.
         Any such loss or damage  aforesaid shall be deemed to constitute a loss
         suffered by Banca del Gottardo and no further  proof or evidence of any
         actual loss shall be required by the Company.

         del Gottardo hereto or thereto,  as the case may be, or, in the case of
         a waiver,  by the party or parties waiving  compliance.  The failure of
         any party at any time or times to require  performance of any provision
         hereof or of any Annex hereto shall in no manner affect the rights at a
         later time to enforce the same. No waiver by any party of any condition

         Annex  hereto,  whether  by conduct  or  otherwise,  in any one or more

                                     ANNEX A

Terms of the "Convertible Notes" of the Company

         Note (the "Global Note"),  without interest coupons, to be deposited by
         the Company  with Banca del  Gottardo on the Payment  Date.  The Global
         Note  may  be  exchanged,  as a  whole  or  in  part,  for  appropriate
         definitive Notes, in bearer form in denominations of USD 5'000. -- with
         the Coupons  attached,  not earlier than 40 days after the later of the
         date on which the Notes are first  offered or the  Payment  Date.  Such
         exchange shall be made upon certification that the beneficial owners of
         the Notes either (i) are not United States  persons or U.S.  persons or
         (ii) are financial  institutions  (as defined in United States Treasury
         Regulation  Section 1. 165-  12(c)(1)(v))  located  outside  the United

         Notes for purposes of resale  directly or indirectly to a United States
         person or U.S.  person within the United  States during the  Restricted
         Period  and that  certify  that  they have not  acquired  the Notes for
         purposes of resale  directly or indirectly to a United States person or
         to a person within the United States.  A beneficial owner of Notes must
         exchange its share of the Global Note for definitive  Notes before such
         Notes or interests  therein may be transferred or interest  payments or
         other payments in respect of the Notes will be made.

         For purposes hereof, (i) the term "Restricted  Period" means the period
         beginning  on the  earlier of the first date that the Notes are offered
         or the date on which the Notes are  issued  (the  "Payment  Date")  and
         ending on the date  forty  (40)  days  after the later of the date upon
         which the Notes and Warrants  were first offered or the date of closing
         of this offering, (ii) the term "United States" means the United States
         of America  (including  the States and the District of  Columbia),  its
         possessions,   its   territories   and  other  areas   subject  to  its
         jurisdiction,  (iii) the term "United States person" means a citizen or
         resident of the United  States,  a  corporation,  partnership  or other
         entity  created or organized in or under the laws of the United  States
         or any political  subdivision thereof, or an estate or trust the income
         of which is subject to United States federal income taxation regardless
         of its source and (iv) the term "U.S. person" has the meaning set forth
         in Sections  230.901 through .904 of Title 17 of the United States Code
         of Federal Regulations ("Regulation S").

(2)      Interest

         The Notes bear  interest  from the  Payment  Date at the rate of 8% per
         annum,  payable  semiannually  in arrear on June 30 and  December 31 of
         each year until  maturity  (the  "Coupon Due Dates")  whereby the first
         payment  shall be made on June 30,  1996 in respect of the period  from
         December 29, 1995 to June 30, 1996.  Such interest is payable in United
         States  Dollars.  Each Note will cease to bear  interest on the date on
         which they become due for  redemption  or repayment  unless  payment of
         principal and/or premium (if any) is improperly  withheld or refused or
         default is otherwise  made in respect of such  payment.  In such event,

         after as before any  judgment)  up to but  excluding  the date on which
         payment in full of the  principal  of such Note is made or (if earlier)
         the date on which, payment in full of the principal thereof having been
         received by Banca del  Gottardo,  notice to that effect shall have been
         given to the holders of the Notes. Interest is computed on the basis of
         a 360-day year of twelve 30-day months.

(3)      Repayment

         The  Company  undertakes  to repay the  principal  amount of the Notes,
         unless previously redeemed, without any previous notice on December 31,
         2000.

(4)      Optional Redemption and Conversion

(a)      The Company reserves the right to call all, but not part, of the out-
         standing Notes for redemption on May 2, 1996, or thereafter up to the 
         close of business on December 15, 2000, at a price of 110% of the 
         principal amount thereof; together with interest accrued to the date 
         of such redemption provided that the average of the daily closing sales
         prices of a Share for a period of 30 consecutive trading days, the last
         day of which trading days is not more than 10 days prior to the day 
         upon which the Company sends a notice to Banca del Gottardo of its 
         intention to redeem the Notes under this sub-section (a), is at least 
         200% of the Conversion Price in effect on such last day (taking into 
         account any retroactive adjustment not then reflected in the Conversion
         Price). The closing sales price for any day shall be the average of the
         closing prices on the New York Stock Exchange and if not listed any 
         longer thereon, the average of the closing bid and asked prices on the
         National Association of Securities Dealers Automated Quotation(NASDAQ).
         All outstanding Notes will become due 60 days after receipt of the 
         aforesaid notice of early redemption by Banca del Gottardo.

         As long as the Shares are listed on a stock  exchange or  exchanges  in
         the United States of America,  reference in this sub-section (a) to the
         sales price for any day shall be deemed to refer to the  closing  price
         (regular way) of a Share as reported by the principal stock exchange on
         which the Shares are  listed  for such day.  If no such sales  price is
         reported  for one or more trading  days,  such day or days shall not be
         deemed  as  trading  day  or  days  and  shall  be  disregarded  in the
         calculation of the said 30 trading day period.

(b)      Each Noteholder will have the right to require the Company to redeem 
         any Note or Notes on December 31, 1999 at a price of 106% of the 
         principal amount thereof, together with interest accrued to the due 
         date of redemption. This right will have to be exercised by giving 
         notice and surrendering the Note(s), so to be redeemed to Banca del 
         Gottardo, Lugano, at any time on or after October 1, 1999 and prior to
         October 31, 1999 accompanied by an irrevocable request for redemption.
         Notes called for redemption will become due on December 31, 1999. Notes
         called for redemption shall cease to bear interest from the date fixed
         for such redemption, unless the Company shall default in providing for
         the payment of the redemption price. The Notes must be presented for 
         repayment with all unmatured Coupons attached. An amount equal to any
         missing unmatured Coupon shall be deducted from the amount due on 
         redemption. Such Coupons shall, however, be paid upon subsequent 
         presentation provided they shall not have become barred pursuant to 
         Section 11 hereof.

                                                                            22.


         Payments with respect to the Notes and Coupons shall be made in dollars
         of the United States of America against  presentation  and surrender of
         such  Notes or Coupons in the manner  specified  below.  Such  payments
         shall be made without cost to the Noteholders,  without any limitations
         and under all circumstances  notwithstanding any transfer restrictions,
         regardless  of  any  bilateral  or  multilateral  payment  or  clearing
         agreement  in  existence  between the United  States of America and the
         Swiss  Confederation,  irrespective  of the  nationality,  residence or
         domicile of any of the Noteholders and without  requiring any affidavit
         or the  fulfillment  of any  formalities.  The funds  required  for the
         payment of principal and interest  shall be made available to Banca del
         Gottardo in  Switzerland  as Paying Agent by the Company  prior to each
         Coupon  Due Date.  The  receipt of the funds by Banca del  Gottardo  in
         Switzerland  shall release the Company from its  obligations in respect
         of the payments due on the respective dates for principal and interest.

         Banca del  Gottardo  will arrange for payment of such funds as and when
         due to the  holders  of Notes and  Coupons.  Notes and  coupons  may be
         presented for payment at the principal  amount printed on the Notes and
         the amount of interest  printed on the  Coupons  only at the offices in
         Switzerland  of Banca del Gottardo.  No payment on the Notes or Coupons
         will be made by  transfer to an account in, or by mailing to an address
         in, the United States.

(6)      Tax Status

         All payments of principal  and interest on the Notes and Coupons by the
         Company  shall  be made  without  deduction  for or on  account  of any
         present  or  future  tax,   assessment  or  other  governmental  charge
         ("Taxes")  imposed upon such payment by the United States of America or
         any political  subdivision or taxing authority  thereof or therein (the
         "United  States").  If the Company shall at any time be required by law
         to withhold any such Taxes, the Company will pay as additional  amounts
         to Banca del  Gottardo  for the  account  of the  holders  of Notes and
         Coupons,  such amounts as may be necessary so that every net payment on
         each Note or Coupon,  after  withholding  for or on account of any such
         Taxes (including any backup  withholding tax or similar charge that may
         be  required  in  order  for  such  payment  to  be  made  without  any
         certification or disclosure of the  nationality,  residence or identity
         of the  beneficial  owner of such Note or Coupon) will not be less than
         the amount  provided  in such Note or Coupon to be then due or payable;
         provided,  however,  that the Company  will not be required to pay such
         additional amounts for or on account of any such Taxes that are imposed
         (i) otherwise than by  withholding  from a payment on a Note or Coupon,
         (ii) upon a holder of a Note or Coupon who is subject  to  taxation  by
         the United States for any reason other than such holder's  ownership or
         receipt of  payments  in  respect  of such Note or Coupon,  or (iii) on
         interest or principal received by a holder of a Note or Coupon which is
         (a) a "10-per cent.  shareholder"  of the Company within the meaning of
         section  871(h)(3)(B)(a)  of the Code,  (b) a bank or an  extension  of
         credit made pursuant to a loan  agreement  entered into in the ordinary
         course of its trade or business,  (c) a controlled foreign  corporation
         which is related to the Company  under  section  864(d)(4) of the Code,
         (d) other than a nonresident  individual or a foreign  corporation  (as
         determined  under  United  States tax  principles)  with respect to the
         United  States,  or (e) a holder whose Note or Coupon is presented  for
         retirement  or  redemption,  or payment is otherwise  made,  other than
         outside  the  United  States  as  provided  in United  States  Treasury
         Regulations.  Any reference in this Note to the payment of principal or
         interest shall be deemed to include  payment of the additional  amounts
         payable pursuant to the provisions of this paragraph.

         If, as the result of any change in,  enactment  of, or amendment to any
         laws or regulations  of the United States or any political  subdivision
         or taxing authorities thereof affecting taxation,  or any change in the
         official  application  of such laws or  regulations,  or any change in,
         execution of or amendment to any treaty or treaties  affecting taxation
         to which the United States is a party,  it is determined by the Company
         that  it  would  be  required  at any  time to pay  additional  amounts
         pursuant to the preceding paragraph,  the Company is entitled to redeem
         the Notes, as a whole but not in part, on giving not more than 60 days'
         but not less than 30 days' prior  notice to Banca del  Gottardo,  on or
         after June 30, 1996 at par.

         Notice of redemption  shall be given by the Company in writing to Banca
         del  Gottardo  and such  notice  so  given  shall  constitute  good and
         sufficient  notice and shall be binding  upon all holders of the Notes,
         regardless of who they may be or where they may be located.

         Banca del Gottardo shall as soon as practicable  notify the Noteholders
         of such redemption in accordance with Section 12 hereof.

         The Company has been advised by Banca del Gottardo that pursuant to the
         Swiss federal laws at present in force,  interest payments on the Notes
         are not subject to Swiss withholding tax.

(7)      Authorizations

         The Company has confirmed to Banca del Gottardo that no  authorizations
         or  approvals  are  required  under the laws of the  United  States for
         performance of its obligations  hereunder,  except for the registration
         requirements provided for herein.

         3.       Payments

                  The Company agrees not to pay to the Holder,  and by accepting
                  this  Note  Holder  agrees  not to take or  receive  from  the
                  Company,  in any manner  whatsoever,  the whole or any part of
                  indebtedness   evidenced  by  this  Note,   including  without
                  limitation  any  payment of  principal  of or interest on this
                  Note, unless and until the Senior Indebtedness shall have been
                  fully   paid   and   satisfied;    provided,   however,   that
                  notwithstanding the foregoing, the Holder shall have the right
                  to receive and retain from the Company,  and the Company shall
                  have the right to pay to the  Holder,  scheduled  payments  of
                  interest only as and when they become due as provided  herein,
                  so long as (i) the Company is not in default  with  respect to
                  any payment of principal,  premium, if any, or interest on any
                  Senior  Indebtedness,  and (ii) no default or event of default
                  exists and is  continuing,  or would exist  immediately  after
                  giving  effect to such  payment  to  Holder,  under any of the
                  terms and  provisions of the documents  relating to any of the
                  Senior Indebtedness.

         4.       Proceedings

                  Holder shall not commence  any action for the  enforcement  of
                  this Note (except an action  commenced to avoid the expiration
                  of an applicable statute of limitations) and will not initiate
                  or join with any creditor,  unless the Majority  Holders shall
                  also join,  in  bringing  any  proceeding  against the Company
                  under any  bankruptcy  or  insolvency  law or  statute  of the
                  federal  or any  state  government  or  under  any such law or
                  statute  relating  to the relief of debtors,  readjustment  of

                  coproponent  of a  plan  of  reorganization  in  a  bankruptcy
                  proceeding,  unless  and until all Senior  Indebtedness  shall
                  have  been  paid  and  satisfied  in  full or the  Holder  has
                  received the prior written consent of the Majority Holders.

                  Should any payment or distribution  (except payments currently
                  due which are received by the Holder as  permitted  herein) be
                  received by the Holder with  respect to this Note prior to the
                  payment and  satisfaction in full of all Senior  Indebtedness,
                  the  Holder  will   forthwith   deliver   such   payments  and
                  distributions  or  proceeds  thereof to the  holders of Senior
                  Indebtedness,  ratably  according to the  aggregate  amount of
                  principal   remaining   unpaid  on  account  of  such   Senior
                  Indebtedness  held by  each in  precisely  the  form  received
                  (except for the endorsements or assignment of the Holder where
                  necessary), for application to the Senior Indebtedness held by
                  such holders, and, until so delivered,  the same shall be held
                  in trust by the Holder as  property  of the  holders of Senior
                  Indebtedness.

         6.       Rights Concerning Senior Indebtedness

                  Without   affecting  the  rights  of  the  holders  of  Senior
                  Indebtedness,  the Holder agrees that,  with or without notice
                  to or further  assent  from the  Holder,  any holder of Senior
                  Indebtedness  may at any time,  and from time to time,  either
                  prior to or after any default by the Company  with  respect to
                  any indebtedness  (a) advance or refuse to advance  additional
                  credit and make other  accommodations to or for the account of
                  the Company,  (b) by written  agreement or otherwise,  extend,
                  refinance,  renew  or  change,  modify,  compromise,  release,
                  refuse to extend,  renew or change the Senior  Indebtedness or
                  any part  thereof and waive any default  under all or any part
                  thereof,  and modify,  rescind or waive any  provision  of any
                  related agreement or collateral undertaking, including but not
                  by way of limitation any provision relating to acceleration or
                  maturity,  (c) fail to set off any or all  accrued  balance or
                  deposit  balances or any part thereof on any holder's books in
                  favor of such  holders  and/or  release  the  same,  (d) sell,
                  surrender,  release,  exchange,  resort  to,  realize  upon or
                  apply, or fail to do any of the foregoing, with respect to any
                  collateral  securing  any  part  thereof  held  by  any of the
                  holders  of Senior  Indebtedness  or  available  to any of the
                  holders of Senior  Indebtedness  for the Senior  Indebtedness,
                  and (e) generally  deal with the Company in such manner as any
                  of the holders of Senior  Indebtedness may see fit, including,
                  without   limiting  the  generality  of  the  foregoing,   any
                  forbearance,  failure,  delay or refusal by any of the holders
                  of Senior  Indebtedness to exercise any rights or remedies any
                  of the  holders of Senior  Indebtedness  may have  against the
                  Company,  all  without  impairing  or  affecting  any of  such
                  holders'  rights and remedies.  Each such action and each such
                  failure to act by any of the  holders  of Senior  Indebtedness
                  shall be  deemed to be at the  request  of the  Holder  and in
                  reliance on this  Agreement.  No failure by any of the holders
                  of Senior  Indebtedness to file,  record or otherwise  perfect
                  any lien or  security  interest,  nor any  improper  filing or
                  recording,  nor any  failure  by any of the  holders of Senior
                  Indebtedness  to insure or protect any of its  collateral  nor
                  any  other   dealing  (or  failure  to  deal)  with  any  such
                  collateral by any of the holders of Senior Indebtedness, shall
                  impair or release  the rights of any of the  holders of Senior
                  Indebtedness hereunder.

         7.       Repayment of Purchaser

                  Notwithstanding  anything to the contrary contained herein, in
                  the  event,  and at  such  time  as,  the  holders  of  Senior
                  Indebtedness,  and their  respective  successors  and assigns,
                  have  been  repaid  in full all such  Senior  Indebtedness  as
                  described  in clauses (A) through (D),  inclusive,  and clause
                  (I) as it relates to clauses (A) through (D) of the definition
                  of

                  "Senior Indebtedness"  contained in this Section 8, Subsection
                  I, hereof,  and all  obligations by the holders of Nomura Debt
                  to  purchase  Series  A  Notes  (as  defined  in the  Purchase
                  Agreement) has  terminated,  and all preference  periods under
                  any  bankruptcy  laws as they  might  apply to the  holders of
                  Senior  Indebtedness,  and it  successors  and  assigns,  have
                  expired,  the restrictions set forth in this Section 8 of this
                  Note shall not  thereafter be applicable to the Holder of this
                  Note.

         8.       Each  holder of Notes  acknowledges  that Nomura is relying on
                  the terms and  provisions of this  Sub-Section 8 in connection
                  with its  execution  of a certain  Limited  Waiver and Consent
                  dated  December 30, 1995 between the Company and Nomura a copy
                  of which  Limited  Waiver  and  Consent  is held by Banca  del
                  Gottardo,  pursuant  to  which  Nomura  has  consented  to the
                  issuance  of the Notes by the  Company,  and each  holder of a
                  Note  hereby  acknowledges  and  agrees  that  the  terms  and
                  provisions of this Sub-Section 8 shall inure to the benefit of
                  Nomura.

(9)      Conversion

         Exhibit I to Annex H attached to the Agreement  dated December 22, 1995
         and entered into between the Company and Banca del  Gottardo,  which is
         available  for  inspection  at the Head  Office  in Lugano of Banca del
         Gottardo,  as Conversion Agent for the Notes,  contains full provisions
         relevant to conversion of the Notes into freely  transferable Shares of
         Common Stock which are duly  registered  under the 1933 Securities Act.
         The following is a summary of such provisions:

         The  conversion  price  will be fixed on March 29,  1996  whereby  such
         conversion  price shall be the equivalent of the average of the closing
         prices during the period from March 14 to March 29, 1996,  but shall in
         any event not be higher  than (i) 120% of the  average  of the  closing
         prices of the shares of Common Stock during the period from December 19
         to 29, 1995, or (ii) USD 4.75 per share of Common  Stock,  whichever is
         lower (Such price hereinafter called the "Conversion Price").

         The  holder  of 10 Notes or more  will be  entitled  at any time on and
         after May 1, 1996 up to the close of  business on  December  31,  2000,
         subject to prior  redemption,  to convert the Notes,  at the  principal
         amount  thereof,  into freely  transferable  and  non-restricted  (such
         non-restriction  being subject to the  effectiveness  of a registration
         statement under the U.S. securities laws covering such common stock, if
         required,)  shares of Common  Stock of the Company,  at the  Conversion
         Price,  subject  to  adjustment  as  described  below.  No  payment  or
         adjustment will be made on conversion of any Note for interest  accrued
         thereon or dividends on any Common  Stock  issued,  except that accrued
         interest  will be paid on the  conversion  of any Note  which  has been
         called for redemption  prior to the conversion date. The Company is not
         required to issue fractional  shares of Common Stock upon conversion of
         Notes and, in lieu thereof,  will pay a cash adjustment  based upon the
         market  price of the Common  Stock on the last trading day prior to the
         date  of  conversion.  In the  case of  Notes  called  for  redemption,
         conversion  rights  will  expire at the close of  business on the fifth
         business day prior to the redemption  date.  Notes may be presented for
         conversion  only to an office of Banca del Gottardo  outside the United
         States  and Banca  del  Gottardo  will  deliver  Common  Stock or other
         consideration  received upon  conversion  only to an account or address
         outside the United States.

         The Conversion  Price is subject to adjustment in the following  events
         occurring after December 29, 1995:

         -        the issuance of stock of the Company as a dividend or 
                  distribution on the Common Stock;

         -        subdivisions of outstanding shares of the Common Stock into a
                  greater number of shares;

         -        combinations of outstanding shares of Common Stock into a 
                  smaller number of shares;

         -        reclassification of the Common Stock into other shares of the
                  Company's capital stock;

         -        issuance to all holders of Common  Stock of certain  rights or
                  warrants  entitling  them to  subscribe  for Common Stock at a
                  price per share less than the current market price but not for
                  shares  issuable  under the  Company's  stock option and stock
                  purchase plans; and

         -        the  distribution  to all  holders  of  Common  Stock  of debt
                  securities  or assets of the  Company or rights or warrants to
                  purchase assets or debt  securities of the Company  (excluding
                  cash dividends or distributions from retained earnings).

         No  adjustment  in the  Conversion  Price  will  be  made  unless  such
         adjustment  would  require an increase or decrease of at least USD 0.05
         in the Conversion  Price then in effect;  but any adjustment that would
         otherwise  be  required  to be made shall be carried  forward and taken
         into account in any subsequent  adjustment.  No adjustment need be made
         for rights to purchase  Common Stock pursuant to a Company  dividend or
         interest  reinvestment  plan.  The  Company  may at any time reduce the
         Conversion  Price by any amount,  provided that the Conversion Price is
         not less than the par value of a share of Common Stock.  If the Company
         consolidates or merges into or transfers or leases all or substantially
         all of its  assets  to any  person,  or is a  party  to a  merger  that
         reclassifies  or changes its outstanding  Common Stock,  the Notes will
         become  convertible  into the kind and  amount of  securities,  cash or
         other   assets  which  the  holders  of  the  Notes  would  have  owned
         immediately  after the  transaction  if the holders had  converted  the
         Notes immediately before the effective date of the transaction.

(10)     Events of Default

         Subject to the  provisions of Section 15, Banca del Gottardo as regards
         all Notes or  holders  having  10% or more of the  aggregate  principal
         amount of all Notes  outstanding  shall  have the right to  declare  by
         notice to the  Company  the Notes held by such  holder of a Note,  plus
         accrued interest,  to be due and payable if any of the following events
         of default shall occur:

         (a)      default in the payment of principal, or, for a period of 15 
                  days, in the payment of interest on any Note; or

         (b)      default  in the  performance  or  observance  in any  material
                  respect of any  covenant  or  agreement  of the Company in the
                  Notes if such default  continues for a period of 30 days after
                  notice thereof has been given to the Company; or

         (c)      a default shall occur under any evidence of  indebtedness  for
                  money  borrowed by the Company or under any  instrument  under
                  which there may be issued or by which there

                                                                            29.


                  may be  secured  or  guaranteed  any  indebtedness  for  money
                  borrowed by the Company, which default involves the failure to
                  pay when due (after any applicable grace period and subject to
                  any extension or postponement of such maturity), or results in
                  the  acceleration  of,  indebtedness in an amount in excess of
                  USD   500'000.--   without  such   indebtedness   having  been
                  discharged or such default or acceleration having been waived,
                  rescinded or annulled, within a period of 30 days after notice
                  thereof shall have been given to the Company; or

         (d)      the entry of a decree or order in respect of the Company in an
                  involuntary  case under any  bankruptcy,  insolvency  or other
                  similar law, or appointing a receiver,  liquidator, trustee or
                  other similar  official of the Company or for any  substantial
                  part  of  its   property,   or  ordering  the  winding  up  or
                  liquidation  of its affairs,  and the  continuance of any such
                  decree  or order  unstayed  and in  effect  for a period of 45
                  consecutive days; or

         (e)      the  Company  shall   commence  a  voluntary  case  under  any
                  bankruptcy, insolvency or other similar law, or consent to the
                  appointment of or taking possession by a receiver, liquidator,
                  trustee or other similar  official,  of the Company or for any
                  substantial  part of its  property,  or the  making by it of a
                  general  assignment  for the  benefit of  creditors,  or if it
                  shall fail  generally  to pay its debts as they become due, or
                  shall take any corporate  action in  furtherance of any of the
                  foregoing; or

          (f) if the Company shall merge or  consolidate,  or sell or convey all
     or substantially  all of its assets to, any other  corporation,  unless (i)
     the  Company  is the  surviving  corporation,  or  (ii)  the  surviving  or
     transferee  corporation  expressly  assumes all  obligations of the Company
     under the Notes by supplemental agreement,  confirmed by an opinion of U.S.
     counsel reasonably  satisfactory to Banca del Gottardo and the Company,  or
     (iii) the Company or the  surviving or transferee  corporation  irrevocably
     deposits  in trust  with  Banca  del  Gottardo,  money  or U.S.  government
     obligations  sufficient  to pay  principal  and  interest  on the  Notes to
     maturity.

         Upon the occurrence of an event of default,  the Company shall promptly
         give notice  thereof to Banca del  Gottardo  which shall  publish  such
         notice of  default in  accordance  with  Section  12 hereof.  Banca del
         Gottardo  shall  in  relation  to any  event of  default  have no other
         obligation than the publication of such event of default.

         The principal  amount of all Notes  declared to be due and payable plus
         accrued  interest  thereon  shall  become due and payable 15 days after
         notice to the Company by Banca del Gottardo or by each holder of a Note
         of such event of  default;  provided,  however,  that such  declaration
         shall be rescinded  if,  within 15 days of such  notice,  such event of
         default shall have been  remedied by payment,  in the case of a payment

         construed  in  accordance  with  Swiss law.  Any action or  proceedings
         against the Company  relating to the Notes may be brought and  enforced
         in the ordinary courts of the Canton of Ticino, venue being in the City
         of  Lugano,  or,  if such  courts  fail to  grant  jurisdiction  in the
         ordinary courts of the Canton of Basle-City,  venue being in Basle, and
         the Company  hereby  irrevocably  submits to the  jurisdiction  of such
         courts in respect of any such action or  proceeding,  with the right to
         appeal, as provided by law, to the Swiss Federal Court in Lausanne, the
         judgment of which shall be final. Solely for that purpose,  the Company
         hereby  elects  legal and  special  domicile at the office of Banca del

         maintain  an  agent  for  service  of  process  in   Switzerland.   The
         aforementioned  jurisdiction  shall also be valid for the  cancellation
         and replacement of lost, stolen, defaced,  mutilated or destroyed Notes
         and  coupons.  Payment  effected  to a  holder  of  Notes  who has been
         identified  as the  legitimate  holder  of a Note or  coupon by a final
         judgment of a Swiss court  shall  release the Company  from its payment
         obligations under such Note or coupon.

         Any  Noteholder  shall also have the right to bring any legal action or
         proceeding  against  the Company in respect of a Note or coupon and all
         covenants contained therein in any state or federal court in the United
         States of America which may have jurisdiction.

                     TERMS OF THE "WARRANTS" OF THE COMPANY

         "Standing  Agent"  as the  case may be)  which  will be  available  for
         inspection  at the  office  in  Lugano  of  the  Warrant  Agent  or its
         successor as Warrant Agent. The holders of the Warrants (the "Holders")
         are deemed to have knowledge of the provisions of such  Agreement,  all
         of which will be binding on them, provided, however, that the rights of
         such Holders hereunder shall be governed by the terms hereof.

         The Standing Agent or the Warrant Agent may resign in its duties and be
         discharged  from  all  further  duties  as Agent  or  Warrant  Agent in
         accordance  with the terms of the  Warrant  Agency  Agreement.  In such
         event a successor  Standing Agent or Warrant Agent, which will have the
         same duties as its  predecessor and will agree to be bound by the terms
         of the Warrant Agency Agreement,  will be appointed by the Company,  or
         if the Company shall fail to appoint such  successor  Standing Agent or
         Warrant Agent, by a court of competent jurisdiction.

         The  Global  Warrant  may be  exchanged,  as a whole  or in  part,  for
         appropriate  definitive  Warrants,  in bearer form, not earlier than 40
         days  after  the  later of the date on which  the  Warrants  are  first
         offered  or  the  Payment  Date.  Such  exchange  shall  be  made  upon

         States  persons  or U.S.  persons  or are  financial  institutions  (as
         defined in United States Treasury Regulation Section 1.165-12(c)(1)(v))

         and that the  beneficial  owners have not  purchased  such Warrants for
         resale  during the  Restricted  Period and that the  beneficial  owners
         certify that they have not acquired the Warrants for purposes of resale

         of this offering, (ii) the term "United States" means the United States
         of America  (including  the States and the District of  Columbia),  its

         230.901  through .904 of Title 17 of the United  States Code of Federal
         Regulations ("Regulation S").

2.       Duration

         The  right to  subscribe  for and  purchase  shares  of  Warrant  Stock
         represented by the Warrants shall commence  Subject to Section 8 hereof
         on May 1, 1996 and  shall  expire  December  31,  2000 at 5:00 P.M.  US
         Eastern Time, provided,  however, that if, on such expiration date, the
         Company is then required, pursuant to an effective request therefor, to
         effect,  or is in the process of effecting,  a  registration  under the
         Securities Act for an  underwritten  public offering in which shares of
         Warrant Stock are,  pursuant to this Warrant,  entitled to be included,
         or if the  Company  is in default  of any  obligations  created by this
         Warrant,  said right to subscribe  for and  purchase  shares of Warrant
         Sock  shall  expire at 5:00  P.M.,  US  Eastern  Time,  on the 30th day
         following  the  date on  which  such  registration  shall  have  become
         effective  (but in no event  longer  than 180 days beyond the date this
         Warrant  otherwise would have expired) or on the 30th day following the
         date all of such defaults have been cured, as the case may be.

3.       Warrant Price; Method of Exercise; Payment; Issuance of New Warrant; 
         Transfer and Exchange

         The  exercise  price  will be fixed  on March  29,  1996  whereby  such
         exercise  price shall be the  equivalent  of the average of the closing
         prices during the period from March 14 to March 29, 1996,  but shall in
         any event not be higher  than (i) 120% of the  average  of the  closing
         prices of the Common  during the period from December 19 to 29, 1995 or
         (ii) USD 4.75 per Common,  whichever  is lower (such price  hereinafter
         called the "Warrant Price").

         The purchase right  represented by this Warrant may be exercised at any
         time and from time to time  prior to  expiration  subject  to Section 8
         hereof.

         In order to exercise the Warrants and receive  certificates  for Shares
         legally  issuable on such  exercise,  the Holder  shall  deposit  2'000
         Warrants  or more with the  Warrant  Agent at its  office in Lugano and
         accompanied   by  a  written   notice  (which  notice  must  contain  a
         certification of non-U.S.  beneficial ownership) signed by or on behalf
         of the Holder to the effect  that such Holder  elects to  exercise  the
         Warrants and payment of the Warrant Price (the  "Warrant  Consideration
         Amount").  As a further  condition  precedent  to the  exercise  of the
         Warrants,  the Holder must pay all stamp, issue,  registration or other
         taxes and duties arising upon exercise in Switzerland or payable in any
         jurisdiction  upon the issue or  delivery  of  Shares,  if any,  to the
         exercising Holder or to the order of a person other than the exercising
         Holder.

         The date on which  these  conditions  precedent  to  exercise as stated
         above have been  verified and  recognized by the Warrant Agent as being
         fulfilled in  hereafter  called the  "Deposit  Date".  The Common Stock
         Warrant  shall be treated as  exercised at the close of business in New
         York on the Exercise  Date.  The "Exercise  Date" for the Warrant means
         the business days in New York  immediately  following the Deposit Date.
         The  "Exercise  Date" for the Common Stock  Warrant  shall not be later
         than the Termination Date.

         The Company  shall not be  obligated  to issue any  fraction of a Share
         upon the  exercise of any Warrant or make any payment for a fraction of
         a Share. If more than one Warrant shall be exercised at one time by the
         same Holder, the number of full Shares which shall be issuable upon


<PAGE>


                                                                            41.

         exercise thereof shall be computed on the basis of the aggregate number
         of shares  issuable upon the exercise of all the Warrants  exercised by
         such  Holder.  Any Shares  issued upon the exercise of the Common Stock
         Warrants shall be delivered in accordance with the  instructions of the
         Holder.

         In the event of any exercise of the rights  represented by this Warrant
         certificates  for the shares of  Warrant  Stock so  purchased  shall be
         dated the date of such  exercise  and  delivered  to the Holder  hereof
         within a reasonable  time,  not exceeding five Business Days after such
         exercise,  and the Holder hereof shall be deemed for all purposes to be
         the Holder of the shares of Warrant  Stock so  purchased as of the date
         of such exercise.

         Neither this Warrant nor any Warrant  Stock has been  registered  under
         the Securities Act.  Accordingly,  neither this Warrant nor any Warrant
         Stock is  transferable  except as permitted  under  various  exemptions
         contained  in  the  Securities   Act,  or  upon   satisfaction  of  the
         registration  and prospectus  delivery  requirements  of the Securities
         Act.

4.       Stock Fully Paid; Reservation of Shares

         The Company covenants and agrees that all shares of Warrant Stock which
         may be issued upon the exercise of this Warrant will, upon issuance, be
         fully  paid and  non-assessable  and free  from all  taxes,  liens  and
         charges with respect to issuance.  The Company  further  covenants  and
         agrees  that  during  the  period  within  which  this  Warrant  may be
         exercised,  the Company will at all times have  authorized and reserved
         for the purpose of the issue upon exercise of the  subscription  rights
         evidenced by this Warrant a sufficient number of shares of Common Stock
         to provide for the exercise of this Warrant. If the Warrant Price is at
         any time less than the par value of the Warrant Stock or if the Warrant
         at any time is exercisable by its delivery alone and without payment of
         any additional consideration,  the Company also covenants and agrees to
         cause to be taken such action  (whether by decreasing  the par value of
         the Warrant  Stock,  the conversion of the Warrant Stock from par value
         to no par value,  or  otherwise)  as will  permit the  exercise of this
         Warrant without any additional payment by the Holder hereof (other than
         payment of the Warrant Price, if any, and applicable transfer taxes, if
         any), and the issuance of the Warrant Stock,  which Warrant Stock, upon
         such issuance, will be fully paid and non-assessable.

         The  Company  shall not by any action  including,  without  limitation,
         amending   its   certificate   of    incorporation   or   through   any
         reorganization, transfer of assets, consolidation, merger, dissolution,
         issue or sale of securities  or any other  voluntary  action,  avoid or
         seek to avoid the observance or performance of any of the terms of this
         Warrant, but will at all times in good faith assist in the carrying out
         of all such  terms  and in the  taking  if all such  actions  as may be
         necessary or  appropriate  to protect the rights of the Holders  hereof
         against  impairment.  Without limiting the generality of the foregoing,
         the Company will (a) not increase the par value of any shares of Common
         Stock  receivable  upon the exercise of this  Warrant  above the amount
         payable therefor upon such exercise  immediately prior to such increase
         in par  value,  (b)  take  all  such  action  as may  be  necessary  or
         appropriate  in order that the Company  may  validly and legally  issue
         fully paid and non-assessable shares of Common Stock, free and clear of
         any  liens,  claims,  encumbrances  and  restrictions  (other  than  as
         provided  herein)  upon the exercise of this  Warrant,  and (c) use its
         best efforts to obtain all such authorizations,  exemptions or consents
         from any public regulatory body having  jurisdiction  thereof as may be
         necessary to enable the Company to perform its  obligations  under this
         Warrant.

5.       Adjustment of Purchase Price and Number of Shares

         The number and kind of securities purchasable upon the exercise of this
         Warrant  and the  payment  of the  Warrant  Price  shall be  subject to
         adjustment  from time to time upon the  happening of certain  events as
         follows:

         a)       Recapitalization, Reorganization, Reclassification, 
                  Consolidation Merger or Sale

                  In  case  of any  recapitalization  or  reorganization  of the
                  Company  or any  reclassification  or  change  of  outstanding
                  Securities  issuable upon exercise of this Warrant (other than
                  a change in par value,  or from par value to no par value,  or
                  from no par value to par value or as a result of a subdivision
                  or combination),  or in case of any consolidation or merger of
                  the Company  with or into  another  corporation  (other than a
                  merger with  another  corporation  in which the Company is the
                  surviving  corporation  and  which  does  not  result  in  any
                  reclassification or change - other than a change in par value,
                  or from par value to no par value, or from no par value to par
                  value,  or as a result of a  subdivision  or  combination - of
                  outstanding   Securities   issuable   upon  exercise  of  this
                  Warrant),  or in  case  of any  sale or  transfer  to  another
                  corporation  of the  Property of the Company as an entirety or
                  substantially  as an entirety in connection with a liquidation
                  or dissolution  of the Company,  the Company or such successor
                  or  purchasing  corporation  therefor,  issue  a new  Warrant,
                  providing  that the  Holder(s) of this Warrant  shall have the
                  right to  exercise  such new  Warrant  and  procure  upon such
                  exercise  in lieu of each share of Warrant  Stock  theretofore
                  issuable  upon  exercise  of this  Warrant  the  kind  and the
                  highest amount of shares of Stock, other securities, money and
                  property     receivable     upon    such     recapitalization,
                  reorganization,   reclassification,   change,   consolidation,
                  merger,  sale or  transfer  by a Holder of one share of Common
                  Stock  issuable  upon  exercise  of this  Warrant  had it been
                  exercised   immediately   prior   to  such   recapitalization,
                  reorganization,   reclassification,   change,   consolidation,
                  merger sale or transfer.  Such new Warrant  shall  provide for
                  adjustments  which  shall be as  nearly  equivalent  as may be
                  practicable to the adjustments provided for in this Section 4.
                  The provisions of this subsection (a) shall similarly apply to
                  successive         recapitalizations,         reorganizations,
                  reclassifications, changes, consolidations, mergers, sales and
                  transfers.

         b)       Subdivision or Combination of Shares

                  If the Company, at any time while this Warrant is outstanding,
                  shall subdivide or combine any class or classes of its Common,
                  (i) in case of subdivision of shares,  the Warrant Price shall
                  be  proportionately  reduced (as at the effective date of such
                  subdivision  of, if the Company shall take a record of Holders
                  of its Common for the  purpose  of so  subdividing,  as at the
                  applicable  record date,  whichever is earlier) to reflect the
                  increase in the total  number of shares of Common  outstanding
                  as a  result  of such  subdivision,  or (ii) in the  case of a
                  combination   of   shares,   the   Warrant   Price   shall  be
                  proportionately  increased (as at the  effective  date of such
                  combination, or, if the Company shall take a record of Holders
                  of its  Common  for the  purpose  of so  combining,  as at the
                  applicable  record date,  whichever is earlier) to reflect the
                  reduction in the total number of shares of Common  outstanding
                  as a result of such combination.

         c)       Certain Dividends and Distributions

                           shall  take a record of the  holders of such class or
                           classes of Common,  for the purpose of receiving such
                           dividend or other  distribution (or if no such record
                           is  taken,  as at the date of such  payment  or other

                           taken,  then  immediately  prior to such  payment  or
                           other distribution),  by a fraction (1) the numerator
                           of which  shall be the  total  number  of  shares  of

                           distribution (plus in the event that the Company paid
                           cash for fractional  shares, the number of additional
                           shares  which  would  have been  outstanding  had the
                           Corporation  issued  fractional  shares in connection

                           exercise  and  payment  of  the  Warrant  Price,   be
                           entitled  to  receive,  in  addition to the number of
                           shares of Warrant  Stock  receivable  thereupon,  and
                           without  payment  of  any  additional   consideration
                           therefor,  a sum equal to the amount of such Property
                           as would have been payable to such Holder as owner of
                           that  number  of  shares  of  Warrant  Stock  of  the

                  provided in the foregoing  subsections (a) through (c) of this
                  Section 4), at a price per share less than the  Warrant  Price

                  without  consideration,  then the Warrant Price upon each such
                  issuance  shall  be  adjusted  to  that  price  determined  by
                  multiplying the Warrant Price by a fraction:

                           or for no consideration:

                           1)       the  numerator  of which shall be the number
                                    of shares of Common outstanding  immediately
                                    prior  to the  issuance  of such  Additional
                                    Shares of Common  plus the  number of shares
                                    of Common which the aggregate  consideration
                                    for the  total  number  of  such  Additional
                                    Shares of Common so issued would purchase at
                                    (i) the Current  Market Price then in effect
                                    if  such  issue  is  pursuant  to  a  public
                                    offering,  or (ii) ninety five percent (95%)
                                    of the Current  Market  Price then in effect
                                    if  such  issue  is  pursuant  to a  private

                                    aggregate, and

                           2)       the denominator of which shall be the number
                                    of shares of Common outstanding immediately 
                                    after the issuance of such Additional Shares
                                    of Common.

                  (B)      If issued for a consideration per share less than the
                           Warrant Price or for no consideration:

                           1)       the  numerator  of which shall be the number
                                    of shares of Common outstanding  immediately
                                    prior  to the  issuance  of such  Additional

                                    Shares of Common so issued would purchase at
                                    the Warrant Price, and

                           2)       the denominator of which shall be the number

                           If such  Additional  Shares of Common shall be issued
                           at a price per share less than both the Warrant Price
                           and the Current Market Price, the Warrant Price shall
                           be adjusted in the manner  provided in clauses (i) or

                           The provisions of this subsection (d) shall not apply

                           shall  be made  under  this  subsection  (d) upon the
                           issuance of any Additional Shares of Common which are
                           issued  pursuant to any Common  Stock  Equivalent  if
                           upon the issuance of such Common Stock Equivalent (1)
                           any  adjustment  shall  have  been made  pursuant  to
                           subsection (e) of this Section 5 or (2) no adjustment
                           was  required  pursuant  to  subsection  (e) of  this

                  e)       Issuance of Common Stock Equivalents

                           In case the  Company  shall at any  time  while  this

                           Equivalent   and  the   price  per  share  for  which
                           Additional   Shares   of  Common   may  be   issuable
                           thereafter  pursuant to such Common Stock  Equivalent
                           shall be less than the  Warrant  Price then in effect
                           on  the  date  of  issuance  of  such  Common   Stock
                           Equivalent or less than (i) the Current  Market Price

                           offering,  or (ii) ninety five  percent  (95%) of the
                           Current  Market Price then in effect if such issue is
                           pursuant  to  a  private  placement  in  excess  of $
                           3'500'000  in the  aggregate,  or if,  after any such
                           issuance of Common Stock  Equivalents,  the price per
                           share for which  Additional  Shares of Common  may be
                           issuable  thereafter  is  amended  (other  than  as a
                           result of the operation of  anti-dilution  provisions
                           of  or   relating   to   Common   Stock   Equivalents
                           outstanding as of the date hereof  pursuant to events
                           or  circumstances  which  would  also  result  in  an
                           adjustment in the Warrant  Price),  and such price as
                           so amended  shall be less than the  Warrant  Price or
                           the  Current  Market  Price in  effect at the time of
                           such amendment, then the Warrant Price upon each such
                           issuance or  amendment  shall be adjusted as provided
                           in the  first  sentence  of  subsection  (d) of  this
                           Section 4 on the basis that (1) the maximum number of
                           Additional  Shares of Common issuable pursuant to all
                           such Common Stock Equivalents shall be deemed to have
                           been  issued   (whether  or  not  such  Common  Stock
                           Equivalents    are   actually    then    exercisable,
                           convertible or  exchangeable  in whole or in part) as
                           of the  earlier of (A) the date on which the  Company
                           shall enter into a firm  contract for the issuance of
                           such  Common  Stock  Equivalent,  or (B) the  date of
                           actual issuance of such Common Stock Equivalent,  and
                           (2) the  aggregate  consideration  for  such  maximum
                           number of Additional Shares of Common shall be deemed
                           to  be  the  minimum   consideration   received   and
                           receivable  by the Company  for the  issuance of such
                           Additional  Shares of Common  pursuant to such Common
                           Stock Equivalent.  No adjustment of the Warrant Price
                           shall  be made  under  this  subsection  (e) upon the
                           issuance of any Convertible  Security which is issued
                           pursuant  to the  exercise  of any  warrants or other
                           subscription  or  purchase  rights  therefor,  if any
                           adjustment  shall  previously  have  been made in the
                           Warrant  Price then in effect  upon the  issuance  of
                           such  warrants  or  other  rights  pursuant  to  this
                           subsection (e).

                  f)       Other Provisions Applicable to Adjustments Under this
                           Section A

                           The following  provisions  shall be applicable to the
                           making   of   adjustments   in  the   Warrant   Price

                                    consideration   received   by  the   Company
                                    therefor,  or, (b) if such Additional Shares
                                    of Common or Common  Stock  Equivalents  are
                                    offered by the Company for subscription, the

                                    underwriting   thereof   or   otherwise   in

                                    the extent that such issuance shall be for a
                                    consideration  other than cash, then, except
                                    as herein otherwise expressly provided,  the
                                    fair market value of such  consideration  at
                                    the time of such  issuance as  determined in
                                    good faith by the Board.  The  consideration
                                    for any Additional Shares of Common issuable
                                    pursuant  to any  Common  Stock  Equivalents
                                    shall be the  consideration  received by the
                                    Corporation  for issuing  such Common  Stock
                                    Equivalents,     plus     the     additional
                                    consideration  payable  to  the  Corporation
                                    upon the exercise, conversion or exchange of
                                    such Common  Stock  Equivalents.  In case of
                                    the  issuance at any time of any  Additional
                                    Shares of Common or Common Stock Equivalents
                                    in payment or  satisfaction  of any dividend
                                    upon any class of Stock  other than  Common,
                                    the  Corporation  shall  be  deemed  to have
                                    received  for  such  Additional   Shares  of
                                    Common  or  Common   Stock   Equivalents   a
                                    consideration  equal  to the  mount  of such
                                    dividend so paid or  satisfied.  In any case
                                    in which the consideration to be received or
                                    paid  shall be other  than  cash,  the Board
                                    shall  notify  the  Holder  of this  Warrant
                                    through    Banca   del   Gottardo   of   its
                                    determination  of the fair  market  value of
                                    such  consideration   prior  to  payment  or
                                    accepting receipt thereof.  If within thirty
                                    days  after  receipt  of  said  notice,  the
                                    Holders of Warrants exercisable for at least
                                    a majority  of Warrant  Stock then  unissued
                                    shall  notify  the Board in writing of their
                                    objection   to   such    determination,    a
                                    determination  of fair market  value of such
                                    consideration  shall be made by  arbitration
                                    in accordance with the Rules of the American
                                    Arbitration Association, by an arbitrator in
                                    the Borough of Manhattan,  City of New York,
                                    State of New York.

                           (ii)     Readjustment of Warrant Price

                                    Upon the expiration of the right to convert,
                                    exchange  or  exercise   any  Common   Stock
                                    Equivalent the issuance of which effected an
                                    adjustment  in the  Warrant  Price,  if such
                                    Common Stock  Equivalent shall not have been
                                    converted,   exercised  or  exchanged,   the
                                    number of shares of Common  Stock  deemed to
                                    be issued and  outstanding  by reason of the
                                    fact   that   they   were    issuable   upon
                                    conversion, exchange or exercise of any such
                                    Common Stock  Equivalent  shall no longer be
                                    computed as set forth above, and the Warrant
                                    Price  shall  forthwith  be  readjusted  and
                                    thereafter  be the price which it would have
                                    been (but  reflecting any other  adjustments
                                    in the  Warrant  Price made  pursuant to the
                                    provisions  of  this  Section  5  after  the
                                    issuance  of such Common  Stock  Equivalent)
                                    had the adjustment of the Warrant Price been
                                    made in accordance with the issuance or sale
                                    of the number of Additional Shares of Common
                                    actually issued upon conversion, exchange or
                                    issuance of such Common Stock

                                    Equivalent  and thereupon only the number of
                                    Additional  Shares  of  Common  actually  so
                                    issued  shall be deemed to have been  issued
                                    and only the consideration actually received
                                    by the Company (computed as in clause (i) of
                                    this subsection (g)) shall be deemed to have
                                    been received by the Company.

                           (iii)    Treasury Shares

                                    The  number  of shares of Common at any time
                                    outstanding  shall not  include  any  shares
                                    thereof then directly or indirectly owned or
                                    held by or for the account of the Company or
                                    any of its Subsidiaries.

                  g)       Other Action Affecting Common

                           In case after the date hereof the Company  shall take
                           any action affecting its common, other than an action
                           described  in any of the  foregoing  subsections  (a)
                           through  (f) of this  Section 5,  inclusive,  and the
                           failure  to make any  adjustment  would  not  failure
                           protect  the  purchase  rights  represented  by  this
                           Warrant in accordance  with the essential  intent and
                           principle of this  Section 5, then the Warrant  Price
                           shall be  adjusted in such manner and at such time as
                           the Board may in good faith determine to be equitable
                           in the circumstances.

                  h)       Adjustment of Number of Shares

                           Upon each adjustment in the Warrant Price pursuant to
                           any provision of this Section 5, the number of shares
                           of  Warrant  Stock  purchasable  hereunder  shall  be
                           adjusted,  to the nearest whole share, to the product
                           obtained  by   multiplying   such  number  of  shares
                           purchasable  immediately  prior to such adjustment in
                           the Warrant  Price by a fraction,  the  numerator  of
                           which shall be the Warrant Price immediately prior to
                           such adjustment and the denominator of which shall be
                           the  Warrant  Price  immediately  thereafter.  If the
                           Company  shall  be in  default  under  any  provision
                           contained  in the last  sentence of Section 5 of this
                           Warrant so that shares  issued at the  Warrant  price
                           adjusted in accordance  with this Section 5 would not
                           be validly issued, the adjustment of number of shares
                           provided  for  in  the   foregoing   sentence   shall
                           nonetheless  be made and the  Holder of this  Warrant
                           shall be entitled to purchase such greater  number of
                           shares at the lowest  price at which such  shares may
                           then be validly  issued under  applicable  law.  Such
                           exercise  shall not  constitute a waiver of any claim
                           arising  against the Company by reason of its default
                           under Section 5 of this Warrant.

                           i) Notwithstanding  anything in this Section 5 to the
                           contrary,  neither  the  number of shares of  Warrant
                           Stock  purchasable  hereunder  nor the Warrant  Price
                           shall be adjusted  with  respect to any Common  Stock
                           Equivalents  issued and outstanding as of the date of
                           the issuance of this Warrant,  or the issuance of any
                           Securities  upon  exercise or  conversion of any such
                           Common   Stock   Equivalent,    including,    without
                           limitation,  any Securities  issued from time to time
                           pursuant to (i) the  exercise of options  outstanding
                           as of the date of issuance of the Warrant and held by
                           present or former directors, officers or employees of
                           the Company, (ii) the

                  writing between the Corporation and the Holder of this Warrant
                  within  fifteen days  immediately  following the date on which
                  the Current Market Price is to be determined.  If no agreement
                  as to Current Market Price is determined as stated herein, (i)
                  the  Holder  of  this  Warrant  shall  select  an  independent
                  appraiser who shall  determine the fair market value per share
                  of the  Common  which  shall  be  the  Current  Market  Price,
                  provided the Company shall agree to such Current Market Price.
                  If the Company shall not agree to the Current  Market Price as
                  determined in the preceding sentence then (ii) the Company and
                  Banca del Gottardo shall each select an independent  appraiser
                  who shall, independently of the other appraiser, determine the
                  fair market value of the Common of the  Company.  If the value
                  determined by the appraiser whose  determination is the higher
                  of the two appraisals does not exceed by more than ten percent
                  (10%) the average of the values  determined by each appraiser,
                  then the  Current  Market  Price  shall be the  average of the
                  values  determined  by  the  two  appraisers.   If  the  value
                  determined by the appraiser whose  determination is the higher
                  of the two  appraisals  does  exceed by more than ten  percent
                  (10%) the average of the value  determined by each  appraiser,
                  then  the two  appraisers  shall  select  a third  independent
                  appraiser who shall,  independently  of the other  appraisals,
                  determine  the fair  market  value of the  Common.  The  value
                  determined by the appraiser  whose  determination  is the most
                  discrepant from the average of the three  appraisals  shall be
                  discarded,  and the  Current  Market  Price  shall  equal  the
                  average of the  remaining two  appraisals;  except that in the
                  event that the  highest  and  lowest  appraisals  are  equally
                  discrepant  from the  average  of the  three  appraisals,  the
                  Current Market Price shall be such average.  The Company shall
                  bear the expenses of all appraisals.

                  "Governmental  Body" shall mean any  federal,  state,  county,

                  Warrants are outstanding it will maintain an agent for service
                  of process in  Switzerland.  The  aforementioned  jurisdiction
                  shall also be valid for the  cancellation  and  replacement of
                  lost,  stolen,  defaced,   mutilated  or  destroyed  Warrants.
                  Issuance of Common  Stock to a Holder who has been  identified
                  as the legitimate  Holder by a final judgment of a Swiss Court

               any legal action or proceeding  hereunder  against the Company in
               any state or federal  court in the United States of America which
               may have jurisdiction.

Article 7         Counterparts

                  This agreement may be executed in any number of  counterparts,
                  each of which  shall  be an  original;  but such  counterparts
                  shall together constitute but one and the same instrument.

                             CONVERSION PROVISIONS


The  following  are  the  provisions  for  the   conversion   (the   "Conversion
Provisions") of the USD  7'500'000.- 8% Convertible  Notes due December 31, 2000
of Intellicall, Inc., Carrollton, Texas (the "Company") into freely transferable
and non-restricted  shares of the common stock of the Company.  Unless otherwise
defined herein,  the terms used herein have the meanings ascribed to them in the
Note and Warrant Purchase,  Paying and Conversion/Exercise  Agency Agreement and
the Conversion  Agency Agreement (the "Agency  Agreement")  dated as of December
22, 1995 between the Company and Banca del Gottardo.



Article I

Conversion Right

     1.1. Subject to and upon compliance with these Conversion  Provisions,  the
holder of any Note (a "Noteholder") will have the right at any time on and after
May 1, 1996 up to the close of business of banks in Lugano on December 31, 2000,
or, in case the Notes are called for redemption in accordance  with Section 4 of
the Terms of the Notes,  then prior to the close of  business of banks in Lugano
on the earlier of December  31, 2000 and the fifth  business day  preceding  the
date fixed for redemption,  but in no event thereafter,  to convert ten Notes or
more Notes into freely  transferable and  non-restricted  (such  non-restriction
being subject to the  effectiveness  of a registration  statement under the U.S.
securities  laws  covering  such common  stock) shares of common stock which are
duly registered under the 1933 Securities Act, with par value USD 0.01 per share
(such  presently  authorized  capital  stock and any other stock into which such
presently authorized common stock may hereafter be changed, the "Common Stock"),
of the Company,  calculated as to each conversion to the greatest number of full
Shares, disregarding fractions, at the price of initially as determined pursuant
to Section 3 of the terms of the Notes for each Share,  such price being subject
to  adjustment  in certain  instances as provided in Article 2 hereafter  (as so
adjusted from time to time, the "Conversion  Price").  Fractions of a share will
not be issued on conversion;  provided, however, that if a Noteholder at any one
time  delivers  more than one Note for  conversion,  the number of Shares issued
shall be calculated on the basis of the aggregate  principal amount of the Notes
so delivered. A cash adjustment shall be paid in respect of any fractional Share
which would  otherwise be issuable  upon  conversion of any Note in an amount in
U.S. Dollars based upon the market price of the Common Stock on the last trading
day prior to the date of conversion. Cash adjustments for fractional shares will
not be made for amounts less than one U.S. Dollar.

     1.2. In order to exercise the right of conversion,  a Noteholder  shall (a)
deliver  the  Note or  Notes  to be  converted  during  normal  business  hours,
accompanied by the conversion  notice in the form obtainable from the Conversion
Agent  (the  "Conversion  Notice")  to any  Conversion  Agent and (b) pay to the
Conversion  Agent any stamp or other taxes that may be payable in Switzerland on
such  conversion.  Each Note delivered for conversion must be delivered with all
unmatured

                                                                            62.


coupons  attached  and/or  with an  amount  equal to the face  value of any
missing,  unmatured  coupons.  Such missing,  unmatured coupons shall be paid by
Banca del Gottardo upon subsequent presentation thereof, provided they shall not
have become barred pursuant to Section 11 of the Terms of the Notes.

     1.3. The Conversion Agent undertakes to:

         (a)      make available to Noteholders the Conversion Notice in such 
                  form as may from time to time be agreed by the Company and 
                  the Conversion Agent;

         (b)      upon receipt of a Conversion Notice from a Noteholder:

                  (i)      verify that (A) the  Conversion  Notice has been duly
                           completed   and   signed  by  or  on  behalf  of  the
                           Noteholder named therein,  (B) the Conversion  Notice
                           is  accompanied  by all Notes to which it relates and
                           all  unmatured  coupons  appertaining  to such  Notes
                           and/or  an  amount  equal  to the  face  value of any
                           missing  unmatured  coupons and (C) the amount of any
                           stamp or other taxes  payable by the  Noteholder  has
                           been paid; and

                  (ii)     endorse the Conversion Notice;

         (c)      imprint or stamp all Notes submitted to it for conversion, and
                  all unmatured  coupons  attached  thereto,  in accordance with
                  Article 4 of the Agency Agreement  promptly upon  satisfaction
                  by  the  Noteholder  of  all   conditions   precedent  to  the
                  conversion, and

         (d)      dispatch  within two business days after  satisfaction  by the
                  Noteholder of all  conditions  precedent to the  conversion to
                  the relevant tax authorities,  payment in respect of any stamp
                  or other taxes payable on the  conversion,  in accordance with
                  the laws of Switzerland.

     1.4. The  Conversion  Agent shall  promptly,  upon the later of the date of
receipt of the Conversion  Notice and the  satisfaction of all other  conditions
precedent to the  conversion  stated above,  endorse the  Conversion  Notice and
notify the  Company  and the Stock  Transfer  Agent of the  Company  (at present
Chemical  Shareholder  Services Group, 2323 Bryan Street, Suite 2300, Dallas, TX
75201),  by  facsimile,  telex or cable of (a) the  principal  amount and serial
numbers of the Notes deposited for conversion, (b) the number of Shares issuable
upon  conversion  of such Notes and (c) the name and address of each person (the
"Shareholder")  to whom such  Shares are to be  issued.  Such  conversion  shall
become effective at the close of business on the date (the "Conversion Date") on
which the Company shall have received at its principal executive offices, during
normal business hours, from the Conversion Agent a telex or cable  notification.
If such  facsimile,  telex or cable  notification is received after the close of
business on such date, the  Conversion  Date will be the  immediately  following
business day. At such  Conversion  Date the rights of the holder (other than the
Company)  of a Note  shall  cease  and the  Shareholder  shall be deemed to have
become the holder of such Shares.

     1.5. As soon as  practicable  on or after the  Conversion  Date,  but in no
event later than seven business days thereafter, the Company shall (a) cause the
Shareholder  to be registered as the owner of the Shares issued upon  conversion
of such Shareholder's Notes in the register of Shareholders of the


<PAGE>


                                                                           63.

Company, (b) make available,  or cause the Stock Transfer Agent to issue, a
certificate  or  certificates  for  such  Shares  registered  in the name of the
Shareholder (together with any other securities,  properties or cash deliverable
at the  Conversion  Date) and (c) at the request of the  Shareholder,  cause the
Stock Transfer Agent to forward, at the risk and expense and for account of such
Shareholder,   such  certificate  or  certificates   (together  with  any  other
securities,  properties or cash  deliverable  upon conversion) to such person or
persons at the address  specified in the Conversion  Notice,  together with such
assignments and other documents, if any, as may be required by law to effect the
transfer   thereof  with  full  benefits   under  the  laws  of  the  applicable
jurisdiction of the United States of America.

     1.6. The Company covenants that:

         (a)      so long as any Notes are outstanding,  it shall keep available
                  authorized  shares of Common  Stock  sufficient  to permit all
                  Notes   outstanding   and   unconverted  to  be  converted  in
                  accordance with these Conversion Provisions;

         (b)      all shares of Common Stock delivered upon conversion of Notes
                  as provided herein will be validly issued, fully-paid and 
                  non-assessable;

         (c)      it shall  file,  on or before May 1, 1996,  if  required,  any
                  registration  under the United States securities laws that may
                  be required before the Shares can be delivered upon conversion
                  of the Notes and freely marketed in the United States.

     1.7.  Shares  issued  upon  conversion  and  registered  in the name of the
Shareholder  shall  be  freely  transferable  and  non-restricted  and  shall be
entitled to receive  all  dividends  paid on such  Common  Stock on or after the
Conversion Date, except for dividends payable to Shareholders registered as such
as of a record date occurring prior to the Conversion Date. No payments shall be
made  upon  conversion  for  interest  accrued  since the  Coupon  Due Date next
preceding the Conversion Date.

     1.8.  Notes  may be  presented  for  conversion  only to an  office  of the
Conversion Agent outside the United States. The Company and the Conversion Agent
will deliver Common Stock or other  consideration  received upon conversion only
to an account or address outside the United States.

Article 2

The  Conversion   Price  shall  be  subject  to  adjustments  in  the  following
circumstances occurring after December 29, 1995:

     2.1. In case the Company  shall  hereafter (i) pay a dividend on its Common
Stock in  shares of its  Common  Stock or make a  distribution  in shares of its
Common Stock with respect to its  outstanding  Common Stock,  (ii) subdivide its
outstanding  shares of Common  Stock  into a greater  number of shares of Common
Stock or (iii)  combine its  outstanding  shares of Common  Stock into a smaller
number of shares of Common Stock,  the Conversion Price in effect at the time of
the record date for such dividend or of the effective  date of such  subdivision
or combination shall be determined by multiplying the Conversion Price in effect
immediately  prior to such record  date or  effective  date by a  fraction,  the
numerator  of which shall be the total  number of  outstanding  shares of Common
Stock immediately prior to such record date or effective date, and the


<PAGE>


                                                                            64.

denominator of which shall be the total number of outstanding  Common Stock
immediately  following such record date or effective date. Such adjustments made
pursuant  to this  Section  2.1 shall be made  successively  whenever  any event
listed above shall occur.

     2.2.  In case the  Company  shall  fix a record  date for the  issuance  of
rights,  options  or  warrants  to all (but not less  than all)  holders  of its
outstanding  Common Stock  entitling them to subscribe for or purchase shares of
Common Stock (or securities  convertible into shares of Common Stock) at a price
per share (or having a  Conversion  Price per share,  if a security  convertible
into Common Stock) less than the Current  Market Price per share of Common Stock
(as defined in Section 2.4) on such record date, the  Conversion  Price to be in
effect after such record date shall be determined by multiplying  the Conversion
Price in effect  immediately  prior to such record date by a fraction,  of which
the numerator shall be the number of shares of Common Stock  outstanding on such
record  date plus the  number of shares  of  Common  Stock  which the  aggregate
offering  price of the total  number of shares of Common  Stock so to be offered
(or the aggregate initial  Conversion Price of the convertible  securities so to
be  offered)  would  purchase  at such  Current  Market  Price  and of which the
denominator  shall be the number of shares of Common Stock  outstanding  on such
record date plus the number of  additional  shares of Common Stock to be offered
for  subscription or purchase (or into which the  convertible  security so to be
offered are initially convertible).  In case such subscription or exercise price
may be paid in a  consideration  part or all of which  shall be in a form  other
than cash, the value of such  consideration  shall be as determined by the Board
of  Directors  of the  Company.  Shares of Common Stock owned by or held for the
account of the  Company  or any  majority-owned  subsidiary  shall not be deemed
outstanding for the purpose of any such  computation.  Such adjustment  shall be
made  successively  whenever such a record date is fixed;  and in the event that
such rights or warrants are not so issued,  the Conversion  Price shall again be
adjusted to be the Conversion Price which would then be in effect if such record
date had not been fixed.

     2.3.  In case the  Company  shall  fix a record  date for the  making  of a
distribution to all (but not less than all) holders of shares of Common Stock of
evidences  of its  indebtedness  or assets  (other than cash  dividends  or cash
distributions  payable out of surplus legally  available for dividends under the
laws  of  the  jurisdiction  of  incorporation  of  the  Company,  dividends  or
distributions  payable in shares of Common Stock as described in Section 2.1, or
rights,  options or warrants or convertible  securities  containing the right to
subscribe for or purchase shares of Common Stock (excluding those referred to in
Section 2.2)), the Conversion Price to be in effect after such record date shall
be determined by multiplying the Conversion Price in effect immediately prior to
such  record  date by a fraction,  of which the  numerator  shall be the Current
Market  Price per share of Common  Stock (as  defined  in  Section  2.4) on such
record date, less the fair market value per share (as determined by the Board of
Directors of the Company, whose determination shall be conclusive, and described
in a statement  filed with Banca del  Gottardo)  of the portion of the assets or
evidences of indebtedness so to be distributed,  or of such rights,  options, or
warrants or convertible securities, applicable to one share of Common Stock, and
of which the denominator  shall be such Current Market Price per share of Common
Stock. Such adjustment shall be made successively whenever such a record date is
fixed;  and in the event that such  distribution  is not so made, the Conversion
Price shall again be adjusted to be the Conversion  Price which would then be in
effect if such record date had not been fixed. If any such rights,  options,  or
warrants or convertible  securities shall by their terms provide for an increase
or   increases,   with  the  passage  of  time,  in  the  amount  of  additional
consideration per share of Common Stock payable to the


<PAGE>


                                                                            65.

Company upon the exercise or conversion thereof,  the Conversion Price then
in  effect  shall,  forthwith  upon any such  increase  becoming  effective,  be
readjusted to reflect such increase.

     2.4.  For the purpose of any  computation  under  Sections 2.2 and 2.3, the
"Current Market Price" means with respect to any Trading Day the last sale price
(regular  way) of the  Common  on such day as  reported  on the New  York  Stock
Exchange  Consolidated  Tape (as published in the Wall Street  Journal),  or, if
such Common Stock is not listed on the New York Stock Exchange, Inc. or reported
on such Consolidated Tape, then the last sale price on such day on the principal
domestic  stock  exchange  on which such  stock is then  listed or  admitted  to
trading, or, if no sale takes place on such day on such exchange, the average of
the  closing  bid and  asked  prices  on such day as  officially  quoted on such
exchange,  or, if such Common Stock is not then listed or admitted to trading on
any  domestic  stock  exchange  but is  quoted  in the  National  Market  System
("NMS/NASDAQ") of the National Association of Securities Dealers, Inc. Automated
Quotation System ("NASDAQ"), then the Current Market Price for each such Trading
Day shall be the last sale price on such day as quoted by NMS/NASDAQ,  or, if no
sale  takes  place on such day or if such  Common  Stock is  neither  listed  or
admitted to trading on any domestic  stock  exchange nor quoted on such National
Market System,  then the Current Market Price for each such Trading Day shall be
the average of the reported  closing bid and asked price  quotations on such day
in the  over-the-counter  market, as reported by NASDAQ, or, if not so reported,
as furnished by the National  Quotation  Bureau,  Inc.,  or, if such firm at the
time is not engaged in the  business of reporting  such prices,  as furnished by
any similar firm then engaged in such business as selected by the Company, or if
there is no such firm, as furnished by any member of the National Association of
Securities  Dealers,  Inc.  selected by the Company with the written approval of
the  Holders of  Warrants  exercisable  for a majority  of the shares of Warrant
Stock issuable under then outstanding Warrants. If at any time such Common Stock
is  not   listed  on  any   domestic   exchange   or  quoted  in  the   domestic
over-the-counter  market,  the  Current  Market  Price  shall be deemed to be an
amount  mutually  agreed  upon in writing  between the Company and the Holder of
this Warrant  within  fifteen days  immediately  following the date on which the
Current Market Price is to be  determined.  If no agreement as to Current Market
Price is  determined  as stated  herein,  (i) the Holder of this  Warrant  shall
select an  independent  appraiser who shall  determine the fair market value per
share of the Common Stock which shall be the Current Market Price,  provided the
Company shall agree to such Current Market Price. If the Company shall not agree
to the Current  Market Price as determined  in the preceding  sentence then (ii)
the Company and Banca del Gottardo  shall each select an  independent  appraiser
who shall, independently of the other appraiser, determine the fair market value
of the Common Stock of the Company.  If the value  determined  by the  appraiser
whose  determination is the higher of the two appraisals does not exceed by more
than ten percent (10%) the average of the values  determined by each  appraiser,
then the Current  Market Price shall be the average of the values  determined by
the two appraisers. If the value determined by the appraiser whose determination
is the higher of the two  appraisals  does exceed by more than ten percent (10%)
the average of the value  determined by each appraiser,  then the two appraisers
shall select a third independent appraiser who shall, independently of the other
appraisals,  determine  the fair  market  value of the Common  Stock.  The value
determined by the appraiser whose  determination is the most discrepant from the
average of the three appraisals shall be discarded, and the Current Market Price
shall  equal the average of the  remaining  two  appraisals;  except that in the
event that the highest and lowest  appraisals  are equally  discrepant  from the
average of the three appraisals, the Current Market Price shall be such average.
The Company shall bear the expenses of all appraisals.

     For the  purpose of this  Section  2.4,  "trading  day" shall mean a day on
which the  securities  exchange  or on NASDAQ  specified  for  purposes  of this
Section 2.4 shall be open for  business  or, if the shares of Common Stock shall
not be listed on such  exchange  for such  period,  a day with  respect to which
quotations of the character  referred to in the next preceding sentence shall be
reported.

     2.5.  In  computing  an  adjustment  in the  Conversion  Price  pursuant to
Sections 2.1 to 2.3 above, shares of Common Stock not outstanding at the time of
such computation  shall be deemed  outstanding to the extent that the Conversion
Price has been  previously  adjusted to reflect  the  issuance of such shares of
Common Stock or rights,  options or warrants to subscribe  for or purchase  such
shares of Common Stock.

     2.6.  Except as stated in Sections 2.1, 2.2 and 2.3 above,  the  Conversion
Price (except at the Company's option) shall not be adjusted for the issuance of
shares of Common  Stock of the  Company  whether or not at less than the Current
Market Price or the current Conversion Price, whether for cash or property.

     2.7.  No  adjustment  shall be made to the  Conversion  Price  unless  such
adjustment  would result in any increase or decrease of at least USD 0.05 in the
Conversion Price then in effect;  provided,  however, that any adjustments which
by reason  of this  Section  2.7 are not  required  to be made  will by  carried
forward and taken into account in any subsequent adjustment.

     2.8. All calculations  under these  Conversion  Provisions shall be made to
the nearest one U.S.  cent,  with 0.5 U.S.  cent or more to be considered a full
U.S. cent, or to the nearest one- hundredth of a share, as the case may be.

     2.9.  Whenever the  Conversion  Price is adjusted as herein  provided,  the
Company shall  promptly send to Banca del Gottardo a certificate  of the Company
setting forth the  Conversion  Price after such  adjustment  and setting forth a
brief  statement of the facts requiring such adjustment and the date on which it
becomes effective.  The contents of any certificate required by this Section 2.9
may be  transmitted  by telex or cable,  but shall be  confirmed  in  writing as
hereinbefore  provided.  Banca del Gottardo may rely upon such  certificate  (or
such transmission by cable or telex,  whether or not so confirmed) as conclusive
evidence of the correctness of the adjustment referred to therein.

     2.10.  Notwithstanding  the foregoing,  no adjustment  shall be made to the
extent that it would reduce the  Conversion  Price to less than the par value of
the shares of Common Stock (USD .01 at the date hereof).

     2.11.  Anything  in this  Article 2 to the  contrary  notwithstanding,  the
Company shall be entitled, but shall not be required, to make such reductions in
the Conversion Price in addition to those required by this Article as it, in its
discretion, shall determine to be advisable.

     2.12. In any case in which this Article shall require that an adjustment be
made  retroactively  immediately  following a record date,  the Company shall as
promptly as  practicable  issue to the holder of any Note  converted  after such
record  date the shares of Common  Stock and other  common  stock of the Company
issuable on such  conversion  in excess of the shares of Common  Stock and other
common  stock of the  Company  issuable on such  conversion  on the basis of the
Conversion Price prior to such adjustment.

Article 3

     3.1. In the event that:

         (a)      the Company  shall  authorize  the  issuance to all holders of
                  shares of Common  Stock of  rights,  options  or  warrants  to
                  subscribe  for or purchase  any shares of Common  Stock or any
                  securities  convertible into shares of Common Stock, or of any
                  other subscription rights or warrants;

         (b)      the Company shall authorize the distribution to all holders of
                  shares of Common  Stock of evidences  of its  indebtedness  or
                  assets  (other  than  cash  dividends  or  cash  distributions
                  payable  out of  consolidated  earnings  or earned  surplus or
                  dividends payable in Common Stock);

         (c)      there  shall be any  consolidation  or  merger  to  which  the

Article 4

So long as any of the Convertible  Notes remain  convertible,  the Company shall
not take any action which would result in an adjustment of the Conversion  Price
pursuant to Article 2 if, after giving  effect  thereto,  the  Conversion  Price
would be  decreased  to such an extent  that the  Shares  could  not be  legally
issued, under applicable law of the jurisdiction of incorporation of the Company
then  in  effect,   at  such  decreased   Conversion  Price  as  fully-paid  and
non-assessable Shares.

Article 5

The Conversion  Agent shall not at any time be responsible to any Noteholder for
determining  whether any facts exist (a) which may require any adjustment of the
Conversion  Price,  (b)  with  respect  to the  nature  or  extent  of any  such
adjustment when made, (c) with respect to the method  employed,  or herein or in
any  supplemental  agreement (if any) provided to be employed in making any such
adjustment.  The Conversion Agent makes no  representation as to the validity or
value  (or the  kind  or  amount)  of any  shares  of  Common  Stock,  or of any
securities,  property or cash, which may at any time be issued or delivered upon
the  conversion  of any  Convertible  Note.  The  Conversion  Agent shall not be
responsible for any failure of the Company to make any cash payment or to issue,
transfer  or  deliver  any  shares  of  stock  or  stock  certificates  or other
securities  or  property  upon the  surrender  of any Note  for the  purpose  of
conversion  or to comply with any of the  covenants of the Company  contained in
these Conversion Provisions.

Article 6

     6.1. In case of any  consolidation  of the Company  with,  or merger of the
Company into, any other  corporation  (other than a  consolidation  or merger in
which the Company is the continuing corporation),  or in the case of any sale or
transfer of all of the assets of the Company as an entirety or  substantially as
an entirety,  the corporation  formed by such  consolidation  or the corporation
into which the  Company  shall have been merged or the  corporation  which shall
have  acquired  such assets,  as the case may be,  shall  execute with Banca del
Gottardo a  supplemental  agreement  which shall (a) provide  that the holder of
each  Convertible  Note  then  outstanding  shall  have  the  right  to  receive
thereafter,  during the period such  Convertible  Note shall be  convertible  as
specified in Article 2, upon  conversion  of such  Convertible  Note, in lieu of
each share of Common Stock  deliverable on such conversion  immediately prior to
such event,  only the kind and amount of shares and/or other  securities  and/or
property  and/or  cash which are  receivable,  or which,  but for the failure to
distribute  to  holders  of  Common  Stock  all  or  substantially  all  of  the
consideration receivable on such sale or transfer of assets, would be receivable
upon such  consolidation,  merger,  sale or transfer by a holder of one share of
Common  Stock of the  Company  and (b) set  forth the  Conversion  Price for the
shares and/or other  securities  and/or property and/or cash so issuable,  which
shall be an amount  equal to the  Conversion  Price per share of Common Stock of
the Company immediately prior to such event.

     6.2.  In case of any  reclassification  or change  of the  shares of Common
Stock  issuable upon  conversion of the Notes (other than a change in par value,
or  from  par  value  to no  par  value,  or as a  result  of a  subdivision  or
combination) or in case of any  consolidation  or merger of another  corporation
into the Company in which the Company is the continuing corporation and in which
the  holders of the shares of Common  Stock  thereafter  receive  shares,  other
securities,  property, cash or any combination thereof for such shares of Common
Stock (including for this purpose shares reflecting

a change in par value or from par value to no par value or as a result of a
subdivision or  combination  of the shares of Common  Stock),  the Company shall
execute with Banca del Gottardo a supplemental agreement which shall (a) provide
that the holder of each Convertible Note then  outstanding  shall receive,  upon
conversion  thereof,  in lieu of each  share  of  Common  Stock  of the  Company
deliverable upon such conversion  immediately  prior to such event, the kind and
amount of shares and/or other securities  and/or property and/or cash receivable
upon such reclassification,  change,  consolidation or merger by a holder of one
share of Common  Stock,  and (b) set forth the  Conversion  Price for the shares
and/or other securities and/or property and/or cash so issuable,  which shall be
an amount equal to the  Conversion  Price per share of Common Stock  immediately
prior to such event.

     6.3.  If, as a result of  Section  6.1 or  Section  6.2,  the holder of any
Convertible Note thereafter  surrendered for conversion shall become entitled to
receive shares of two or more classes of common stock of the Company,  the Board
of Directors  (whose  determination  shall be  conclusive)  shall  determine the
allocation  of the  Conversion  Price between or among shares of such classes of
capital stock. Any supplemental  agreement executed pursuant to Sections 6.1 and
6.2  shall  provide  for  adjustments  which  shall be as nearly  equivalent  as
practicable to the  adjustments  provided for herein,  and,  where  appropriate,
state the  Conversion  Price in terms of one full  share of Common  Stock or one
full share of common stock of any successor or purchasing corporation. The terms
of this Article 6 also shall apply to successive  consolidations,  merger, sales
or transfers.  In the event that at any time as a result of an  adjustment  made
pursuant to this  Article 6 the holder of any Note  thereafter  surrendered  for
conversion  shall become entitled to receive any shares or securities other than
shares of Common Stock,  thereafter  the prices or price of such other shares or
other  securities so receivable on conversion of any  Convertible  Note shall be
subject  to  adjustment  from  time to time in a manner  and on terms as  nearly
equivalent  as  practicable  to the  provisions  with  respect  to Common  Stock
contained  in Article  2, and the  provisions  of Article 2 with  respect to the
Common Stock shall apply on like terms to any such other shares.

     6.4.  The   Conversion   Agent  shall  have  no   responsibility   for  any
consolidation,  merger,  sale or  transfer,  the form or  substance  or any plan
relating thereto or the consequences thereof to any Noteholder.

     The  Conversion  Agent  shall  have  no  responsibility  to  determine  the
correctness of any provision  contained in any supplemental  agreement  relating
either  to the kind or  amount of  shares  of stock or  securities  or  property
receivable by Noteholders upon the conversion of their  Convertible  Notes after
any such consolidation, merger, sale or transfer, or to any adjustment made with
respect thereto. The Conversion Agent may, at its option,  receive an opinion of
counsel  for the  Company  as  conclusive  evidence  that any such  supplemental
agreement complies with the provisions of this Article.

                                            Its:









                                                                            1

                Terms of the "Convertible Notes" of the Company

         Note (the "Global Note"),  without interest coupons, to be deposited by
         the Company  with Banca del  Gottardo on the Payment  Date.  The Global
         Note  may  be  exchanged,  as a  whole  or  in  part,  for  appropriate
         definitive Notes, in bearer form in denominations of USD 5'000. -- with

         date on which the Notes are first  offered or the  Payment  Date.  Such
         exchange shall be made upon certification that the beneficial owners of
         the Notes either (i) are not United States  persons or U.S.  persons or
         (ii) are financial  institutions  (as defined in United States Treasury
         Regulation  Section 1. 165-  12(c)(1)(v))  located  outside  the United
         States that are not United States  persons and that have purchased such
         Notes for purposes of resale  directly or indirectly to a United States
         person or U.S.  person within the United  States during the  Restricted
         Period  and that  certify  that  they have not  acquired  the Notes for
         purposes of resale  directly or indirectly to a United States person or
         to a person within the United States.  A beneficial owner of Notes must
         exchange its share of the Global Note for definitive  Notes before such
         Notes or interests  therein may be transferred or interest  payments or
         other payments in respect of the Notes will be made.

         For purposes hereof, (i) the term "Restricted  Period" means the period
         beginning  on the  earlier of the first date that the Notes are offered
         or the date on which the Notes are  issued  (the  "Payment  Date")  and
         ending on the date  forty  (40)  days  after the later of the date upon
         which the Notes and Warrants  were first offered or the date of closing
         of this offering, (ii) the term "United States" means the United States
         of America  (including  the States and the District of  Columbia),  its
         possessions,   its   territories   and  other  areas   subject  to  its
         jurisdiction,  (iii) the term "United States person" means a citizen or
         resident of the United  States,  a  corporation,  partnership  or other
         entity  created or organized in or under the laws of the United  States
         or any political  subdivision thereof, or an estate or trust the income
         of which is subject to United States federal income taxation regardless
         of its source and (iv) the term "U.S. person" has the meaning set forth
         in Sections  230.901 through .904 of Title 17 of the United States Code
         of Federal Regulations ("Regulation S").

(2)      Interest

         The Notes bear  interest  from the  Payment  Date at the rate of 8% per
         annum,  payable  semiannually  in arrear on June 30 and  December 31 of
         each year until  maturity  (the  "Coupon Due Dates")  whereby the first
         payment  shall be made on June 30,  1996 in respect of the period  from
         December 29, 1995 to June 30, 1996.  Such interest is payable in United
         States  Dollars.  Each Note will cease to bear  interest on the date on
         which they become due for  redemption  or repayment  unless  payment of
         principal and/or premium (if any) is improperly  withheld or refused or
         default is otherwise  made in respect of such  payment.  In such event,
         interest will continue to accrue (as well

                                                                            2.

         after as before any  judgment)  up to but  excluding  the date on which
         payment in full of the  principal  of such Note is made or (if earlier)
         the date on which, payment in full of the principal thereof having been
         received by Banca del  Gottardo,  notice to that effect shall have been
         given to the holders of the Notes. Interest is computed on the basis of
         a 360-day year of twelve 30-day months.

(3)      Repayment

         The  Company  undertakes  to repay the  principal  amount of the Notes,
         unless previously redeemed, without any previous notice on December 31,
         2000.

(4)      Optional Redemption and Conversion

(a)      The Company reserves the right to call all, but not part, of the out-
         standing Notes for redemption on May 2, 1996, or thereafter up to the 
         close of business on December 15, 2000, at a price of 110% of the 
         principal amount thereof; together with interest accrued to the date 
         of such redemption provided that the average of the daily closing sales
         prices of a Share for a period of 30 consecutive trading days, the last
         day of which trading days is not more than 10 days prior to the day 
         upon which the Company sends a notice to Banca del Gottardo of its 
         intention to redeem the Notes under this sub-section (a), is at least 
         200% of the Conversion Price in effect on such last day (taking into 
         account any retroactive adjustment not then reflected in the Conversion
         Price). The closing sales price for any day shall be the average of the
         closing prices on the New York Stock Exchange and if not listed any 
         longer thereon, the average of the closing bid and asked prices on the
         National Association of Securities Dealers Automated Quotation(NASDAQ).
         All outstanding Notes will become due 60 days after receipt of the 
         aforesaid notice of early redemption by Banca del Gottardo.

         As long as the Shares are listed on a stock  exchange or  exchanges  in
         the United States of America,  reference in this sub-section (a) to the
         sales price for any day shall be deemed to refer to the  closing  price
         (regular way) of a Share as reported by the principal stock exchange on
         which the Shares are  listed  for such day.  If no such sales  price is
         reported  for one or more trading  days,  such day or days shall not be
         deemed  as  trading  day  or  days  and  shall  be  disregarded  in the
         calculation of the said 30 trading day period.

(b)      Each Noteholder will have the right to require the Company to redeem 
         any Note or Notes on December 31, 1999 at a price of 106% of the 
         principal amount thereof, together with interest accrued to the due 
         date of redemption. This right will have to be exercised by giving 
         notice and surrendering the Note(s), so to be redeemed to Banca del 
         Gottardo, Lugano, at any time on or after October 1, 1999 and prior to
         October 31, 1999 accompanied by an irrevocable request for redemption.
         Notes called for redemption will become due on December 31, 1999. Notes
         called for redemption shall cease to bear interest from the date fixed
         for such redemption, unless the Company shall default in providing for
         the payment of the redemption price. The Notes must be presented for 
         repayment with all unmatured Coupons attached. An amount equal to any
         missing unmatured Coupon shall be deducted from the amount due on 
         redemption. Such Coupons shall, however, be paid upon subsequent 
         presentation provided they shall not have become barred pursuant to 
         Section 11 hereof.

(5)      Payments

                                                                            3.


         Payments with respect to the Notes and Coupons shall be made in dollars
         of the United States of America against  presentation  and surrender of
         such  Notes or Coupons in the manner  specified  below.  Such  payments
         shall be made without cost to the Noteholders,  without any limitations
         and under all circumstances  notwithstanding any transfer restrictions,
         regardless  of  any  bilateral  or  multilateral  payment  or  clearing
         agreement  in  existence  between the United  States of America and the
         Swiss  Confederation,  irrespective  of the  nationality,  residence or
         domicile of any of the Noteholders and without  requiring any affidavit
         or the  fulfillment  of any  formalities.  The funds  required  for the
         payment of principal and interest  shall be made available to Banca del
         Gottardo in  Switzerland  as Paying Agent by the Company  prior to each
         Coupon  Due Date.  The  receipt of the funds by Banca del  Gottardo  in
         Switzerland  shall release the Company from its  obligations in respect
         of the payments due on the respective dates for principal and interest.

         Banca del  Gottardo  will arrange for payment of such funds as and when
         due to the  holders  of Notes and  Coupons.  Notes and  coupons  may be
         presented for payment at the principal  amount printed on the Notes and
         the amount of interest  printed on the  Coupons  only at the offices in
         Switzerland  of Banca del Gottardo.  No payment on the Notes or Coupons
         will be made by  transfer to an account in, or by mailing to an address
         in, the United States.

(6)      Tax Status

         All payments of principal  and interest on the Notes and Coupons by the
         Company  shall  be made  without  deduction  for or on  account  of any
         present  or  future  tax,   assessment  or  other  governmental  charge
         ("Taxes")  imposed upon such payment by the United States of America or
         any political  subdivision or taxing authority  thereof or therein (the
         "United  States").  If the Company shall at any time be required by law
         to withhold any such Taxes, the Company will pay as additional  amounts
         to Banca del  Gottardo  for the  account  of the  holders  of Notes and
         Coupons,  such amounts as may be necessary so that every net payment on
         each Note or Coupon,  after  withholding  for or on account of any such
         Taxes (including any backup  withholding tax or similar charge that may
         be  required  in  order  for  such  payment  to  be  made  without  any
         certification or disclosure of the  nationality,  residence or identity
         of the  beneficial  owner of such Note or Coupon) will not be less than
         the amount  provided  in such Note or Coupon to be then due or payable;
         provided,  however,  that the Company  will not be required to pay such
         additional amounts for or on account of any such Taxes that are imposed
         (i) otherwise than by  withholding  from a payment on a Note or Coupon,
         (ii) upon a holder of a Note or Coupon who is subject  to  taxation  by
         the United States for any reason other than such holder's  ownership or
         receipt of  payments  in  respect  of such Note or Coupon,  or (iii) on
         interest or principal received by a holder of a Note or Coupon which is
         (a) a "10-per cent.  shareholder"  of the Company within the meaning of
         section  871(h)(3)(B)(a)  of the Code,  (b) a bank or an  extension  of
         credit made pursuant to a loan  agreement  entered into in the ordinary
         course of its trade or business,  (c) a controlled foreign  corporation
         which is related to the Company  under  section  864(d)(4) of the Code,
         (d) other than a nonresident  individual or a foreign  corporation  (as
         determined  under  United  States tax  principles)  with respect to the
         United  States,  or (e) a holder whose Note or Coupon is presented  for
         retirement  or  redemption,  or payment is otherwise  made,  other than
         outside  the  United  States  as  provided  in United  States  Treasury
         Regulations.  Any reference in this Note to the payment of principal or
         interest shall be deemed to include  payment of the additional  amounts
         payable pursuant to the provisions of this paragraph.

                                                                            4.

         If, as the result of any change in,  enactment  of, or amendment to any
         laws or regulations  of the United States or any political  subdivision
         or taxing authorities thereof affecting taxation,  or any change in the
         official  application  of such laws or  regulations,  or any change in,
         execution of or amendment to any treaty or treaties  affecting taxation
         to which the United States is a party,  it is determined by the Company
         that  it  would  be  required  at any  time to pay  additional  amounts
         pursuant to the preceding paragraph,  the Company is entitled to redeem
         the Notes, as a whole but not in part, on giving not more than 60 days'
         but not less than 30 days' prior  notice to Banca del  Gottardo,  on or
         after June 30, 1996 at par.

         Notice of redemption  shall be given by the Company in writing to Banca
         del  Gottardo  and such  notice  so  given  shall  constitute  good and
         sufficient  notice and shall be binding  upon all holders of the Notes,
         regardless of who they may be or where they may be located.

         Banca del Gottardo shall as soon as practicable  notify the Noteholders
         of such redemption in accordance with Section 12 hereof.

         The Company has been advised by Banca del Gottardo that pursuant to the
         Swiss federal laws at present in force,  interest payments on the Notes
         are not subject to Swiss withholding tax.

(7)      Authorizations

         The Company has confirmed to Banca del Gottardo that no  authorizations
         or  approvals  are  required  under the laws of the  United  States for
         performance of its obligations  hereunder,  except for the registration
         requirements provided for herein.

(8)      Status of the Notes and Subordination

         1.       Note Subordinated to Senior Indebtedness

                  The Company, for itself, its successors and assigns, covenants
                  and agrees, and each Holder of this Note ("Holder"), by his or
                  its acceptance hereof, likewise covenants and agrees, that the
                  indebtedness   evidenced  by  this  Note  (and  any  renewals,
                  refinancings,  modifications or extensions thereof), including
                  the principal of and interest thereon and any interest payable
                  on such interest and all fees,  costs and expenses  (including
                  attorneys'  fees and  collection  costs) payable in connection
                  with this Note, and all requirements of the Company  contained
                  in this  Note  shall be  subordinate  and  junior  in right of
                  payment,  to the  extent  and in the  manner  hereinafter  set
                  forth, to the prior payment in full of all Senior Indebtedness
                  (as  hereinafter  defined),  and that  each  holder  of Senior
                  Indebtedness  whether now  outstanding  or hereafter  created,
                  incurred,  assumed  or  guaranteed  shall  be  deemed  to have

                  collateral by any of the holders of Senior Indebtedness, shall
                  impair or release  the rights of any of the  holders of Senior
                  Indebtedness hereunder.

         lower (Such price hereinafter called the "Conversion Price").

         The  holder  of 10 Notes or more  will be  entitled  at any time on and
         after May 1, 1996 up to the close of  business on  December  31,  2000,
         subject to prior  redemption,  to convert the Notes,  at the  principal
         amount  thereof,  into freely  transferable  and  non-restricted  (such
         non-restriction  being subject to the  effectiveness  of a registration
         statement under the U.S. securities laws covering such common stock, if
         required,)  shares of Common  Stock of the Company,  at the  Conversion
         Price,  subject  to  adjustment  as  described  below.  No  payment  or
         adjustment will be made on conversion of any Note for interest  accrued
         thereon or dividends on any Common  Stock  issued,  except that accrued
         interest  will be paid on the  conversion  of any Note  which  has been
         called for redemption  prior to the conversion date. The Company is not
         required to issue fractional  shares of Common Stock upon conversion of
         Notes and, in lieu thereof,  will pay a cash adjustment  based upon the
         market  price of the Common  Stock on the last trading day prior to the
         date  of  conversion.  In the  case of  Notes  called  for  redemption,
         conversion  rights  will  expire at the close of  business on the fifth
         business day prior to the redemption  date.  Notes may be presented for
         conversion  only to an office of Banca del Gottardo  outside the United
         States  and Banca  del  Gottardo  will  deliver  Common  Stock or other
         consideration  received upon  conversion  only to an account or address
         outside the United States.

         The Conversion  Price is subject to adjustment in the following  events
         occurring after December 29, 1995:

         -        the issuance of stock of the Company as a dividend or 
                  distribution on the Common Stock;

         -        subdivisions of outstanding shares of the Common Stock into a
                  greater number of shares;

         -        combinations of outstanding shares of Common Stock into a 
                  smaller number of shares;

         -        reclassification of the Common Stock into other shares of the
                  Company's capital stock;

         -        issuance to all holders of Common  Stock of certain  rights or
                  warrants  entitling  them to  subscribe  for Common Stock at a
                  price per share less than the current market price but not for
                  shares  issuable  under the  Company's  stock option and stock
                  purchase plans; and

         -        the  distribution  to all  holders  of  Common  Stock  of debt
                  securities  or assets of the  Company or rights or warrants to
                  purchase assets or debt  securities of the Company  (excluding
                  cash dividends or distributions from retained earnings).

         No  adjustment  in the  Conversion  Price  will  be  made  unless  such
         adjustment  would  require an increase or decrease of at least USD 0.05
         in the Conversion  Price then in effect;  but any adjustment that would
         otherwise  be  required  to be made shall be carried  forward and taken
         into account in any subsequent  adjustment.  No adjustment need be made
         for rights to purchase  Common Stock pursuant to a Company  dividend or
         interest  reinvestment  plan.  The  Company  may at any time reduce the
         Conversion  Price by any amount,  provided that the Conversion Price is
         not less than the par value of a share of Common Stock.  If the Company
         consolidates or merges into or transfers or leases all or substantially
         all of its  assets  to any  person,  or is a  party  to a  merger  that
         reclassifies  or changes its outstanding  Common Stock,  the Notes will
         become  convertible  into the kind and  amount of  securities,  cash or
         other   assets  which  the  holders  of  the  Notes  would  have  owned
         immediately  after the  transaction  if the holders had  converted  the
         Notes immediately before the effective date of the transaction.

                  USD   500'000.--   without  such   indebtedness   having  been
                  discharged or such default or acceleration having been waived,

                  trustee or other similar  official,  of the Company or for any
                  substantial  part of its  property,  or the  making by it of a
                  general  assignment  for the  benefit of  creditors,  or if it
                  shall fail  generally  to pay its debts as they become due, or
                  shall take any corporate  action in  furtherance of any of the

         accrued  interest  thereon  shall  become due and payable 15 days after
         notice to the Company by Banca del Gottardo or by each holder of a Note
         of such event of  default;  provided,  however,  that such  declaration
         shall be rescinded  if,  within 15 days of such  notice,  such event of

               shall  form a  quorum,  provided  that  if the  business  of such
               further  adjourned  Meeting includes  consideration of a proposed

               present  holding  one-third  or more of the  aggregate  principal
               amount of all Notes for the time being outstanding.

                    g) Notice of any  adjourned  Meeting  or  further  adjourned
               Meeting  shall  be  given  in the same  manner  as  notice  of an
               original  Meeting and such notice shall state,  in the case of an
               adjourned  Meeting,  that two or more persons present holding 10%

               consideration of a proposed Extraordinary Resolution,  one-third)
               or more of the  aggregate  principal  amount of all Notes for the
               time being  outstanding will form a quorum,  or, in the case of a
               further  adjourned  Meeting,  that  two or more  persons  present
               holding  any Notes  outstanding  (or in the case of a Meeting the
               business  of  which  includes  the  consideration  of a  proposed
               Extraordinary  Resolution,  two or more persons  present  holding
               one-third or more of the aggregate  principal amount of all Notes
               for the time being outstanding), shall form a quorum.

                    h) The  voting  rights  of the  holders  of  Notes  shall be
               determined  according to the principal amount of Notes held, each
               Note with a principal  amount of USD 5'000.-  giving the right to
               one  vote.  Holders  of the  Coupons  shall  not have any  voting
               rights.  Notes held by or on behalf of the Company  shall have no
               voting  rights and shall be  disregarded  for the purpose of this
               Section 15,  save that the  Company  shall be entitled to vote in
               respect  of  Notes  held  by it  for  the  benefit  of and at the
               direction of an independent third party. In

               and any other  person  authorized  on its behalf by it may attend
               and speak at any Meeting.

                    j) The Meeting shall have the following  powers  exercisable
               by Extraordinary Resolution with the consent of the Company:

                    (i)  extension  of the date fixed for final  maturity of the
               Notes;

                    (ii) reduction or cancellation  of the principal  payable on

               Coupons;

                    (iv)  alteration  of  the  majority   required  to  pass  an
               Extraordinary Resolution; and

                    (v) waiver of any Event of Default.

                    k)  Any  reference  in  these  Terms  of  the  Notes  to  an
               "Extraordinary  Resolution"  shall be construed as  references to
               resolutions  of the  Noteholders  passed in  accordance  with the
               foregoing  provisions  of this  Section 15 with respect to any of
               the matters stated in sub-section j) above.

(16)     Applicable Law and Jurisdiction

         The terms,  conditions  and form of the Notes and Coupons  (the English
         language  version  of which  shall  govern)  shall be  governed  by and
         construed  in  accordance  with  Swiss law.  Any action or  proceedings
         against the Company  relating to the Notes may be brought and  enforced
         in the ordinary courts of the Canton of Ticino, venue being in the City
         of  Lugano,  or,  if such  courts  fail to  grant  jurisdiction  in the
         ordinary courts of the Canton of Basle-City,  venue being in Basle, and
         the Company  hereby  irrevocably  submits to the  jurisdiction  of such
         courts in respect of any such action or  proceeding,  with the right to
         appeal, as provided by law, to the Swiss Federal Court in Lausanne, the
         judgment of which shall be final. Solely for that purpose,  the Company
         hereby  elects  legal and  special  domicile at the office of Banca del
         Gottardo,  Viale  Stefano  Franscini 8, 6901 Lugano,  Switzerland.  The
         Company  covenants  that so long as any Notes are  outstanding  it will
         maintain  an  agent  for  service  of  process  in   Switzerland.   The
         aforementioned  jurisdiction  shall also be valid for the  cancellation
         and replacement of lost, stolen, defaced,  mutilated or destroyed Notes
         and  coupons.  Payment  effected  to a  holder  of  Notes  who has been
         identified  as the  legitimate  holder  of a Note or  coupon by a final
         judgment of a Swiss court  shall  release the Company  from its payment
         obligations under such Note or coupon.

         Any  Noteholder  shall also have the right to bring any legal action or
         proceeding  against  the Company in respect of a Note or coupon and all
         covenants contained therein in any state or federal court in the United
         States of America which may have jurisdiction.


                                                                           1.

                     TERMS OF THE "WARRANTS" OF THE COMPANY


1.       General


         The  Warrants  are  issuable in bearer form and have the benefit of and
         are subject to the provisions for the exercise thereof contained in the
         Warrant  Agency  Agreement  to be dated as of December 22, 1995 between
         the  Company  and  Banca  del  Gottardo  (the  "Warrant  Agent"  or the
         "Standing  Agent"  as the  case may be)  which  will be  available  for
         inspection  at the  office  in  Lugano  of  the  Warrant  Agent  or its
         successor as Warrant Agent. The holders of the Warrants (the "Holders")
         are deemed to have knowledge of the provisions of such  Agreement,  all
         of which will be binding on them, provided, however, that the rights of
         such Holders hereunder shall be governed by the terms hereof.

         The Standing Agent or the Warrant Agent may resign in its duties and be
         discharged  from  all  further  duties  as Agent  or  Warrant  Agent in
         accordance  with the terms of the  Warrant  Agency  Agreement.  In such
         event a successor  Standing Agent or Warrant Agent, which will have the
         same duties as its  predecessor and will agree to be bound by the terms
         of the Warrant Agency Agreement,  will be appointed by the Company,  or
         if the Company shall fail to appoint such  successor  Standing Agent or
         Warrant Agent, by a court of competent jurisdiction.

         The  Global  Warrant  may be  exchanged,  as a whole  or in  part,  for
         appropriate  definitive  Warrants,  in bearer form, not earlier than 40
         days  after  the  later of the date on which  the  Warrants  are  first
         offered  or  the  Payment  Date.  Such  exchange  shall  be  made  upon
         certification that the beneficial owners of the Warrants are not United
         States  persons  or U.S.  persons  or are  financial  institutions  (as
         defined in United States Treasury Regulation Section 1.165-12(c)(1)(v))
         located  outside the United States that are not United  States  persons
         and that the  beneficial  owners have not  purchased  such Warrants for
         resale  during the  Restricted  Period and that the  beneficial  owners
         certify that they have not acquired the Warrants for purposes of resale
         directly or  indirectly to a United States person or to a person within
         the United States.  A beneficial owner of Notes must exchange its share

         be transferred or shares may be delivered upon exercise of the Warrants
         in respect of the Warrants will be made.

         or the date on which the Notes are  issued  (the  "Payment  Date")  and
         ending on the date  forty  (40)  days  after the later of the date upon
         which the Notes and Warrants  were first offered or the date of closing
         of this offering, (ii) the term "United States" means the United States
         of America  (including  the States and the District of  Columbia),  its
         possessions,   its   territories   and  other  areas   subject  to  its
         jurisdiction,  (iii) the term "United States person" means a citizen or
         resident of the United  States,  a  corporation,  partnership  or other
         entity  created or organized in or under the laws of the United  States
         or any political  subdivision thereof, or an estate or trust the income
         of which is subject to United States federal income taxation regardless
         of its source and (iv) the term "U.S. person" has the meaning set forth
         in Sections

                                                                           2.

         230.901  through .904 of Title 17 of the United  States Code of Federal
         Regulations ("Regulation S").

2.       Duration

         The  right to  subscribe  for and  purchase  shares  of  Warrant  Stock
         represented by the Warrants shall commence  Subject to Section 8 hereof
         on May 1, 1996 and  shall  expire  December  31,  2000 at 5:00 P.M.  US
         Eastern Time, provided,  however, that if, on such expiration date, the
         Company is then required, pursuant to an effective request therefor, to
         effect,  or is in the process of effecting,  a  registration  under the
         Securities Act for an  underwritten  public offering in which shares of
         Warrant Stock are,  pursuant to this Warrant,  entitled to be included,
         or if the  Company  is in default  of any  obligations  created by this
         Warrant,  said right to subscribe  for and  purchase  shares of Warrant
         Sock  shall  expire at 5:00  P.M.,  US  Eastern  Time,  on the 30th day
         following  the  date on  which  such  registration  shall  have  become
         effective  (but in no event  longer  than 180 days beyond the date this
         Warrant  otherwise would have expired) or on the 30th day following the
         date all of such defaults have been cured, as the case may be.

3.       Warrant Price; Method of Exercise; Payment; Issuance of New Warrant; 
         Transfer and Exchange

         The  exercise  price  will be fixed  on March  29,  1996  whereby  such
         exercise  price shall be the  equivalent  of the average of the closing
         prices during the period from March 14 to March 29, 1996,  but shall in
         any event not be higher  than (i) 120% of the  average  of the  closing
         prices of the Common  during the period from December 19 to 29, 1995 or
         (ii) USD 4.75 per Common,  whichever  is lower (such price  hereinafter
         called the "Warrant Price").

         The purchase right  represented by this Warrant may be exercised at any
         time and from time to time  prior to  expiration  subject  to Section 8
         hereof.

         In order to exercise the Warrants and receive  certificates  for Shares
         legally  issuable on such  exercise,  the Holder  shall  deposit  2'000
         Warrants  or more with the  Warrant  Agent at its  office in Lugano and
         accompanied   by  a  written   notice  (which  notice  must  contain  a
         certification of non-U.S.  beneficial ownership) signed by or on behalf
         of the Holder to the effect  that such Holder  elects to  exercise  the
         Warrants and payment of the Warrant Price (the  "Warrant  Consideration
         Amount").  As a further  condition  precedent  to the  exercise  of the
         Warrants,  the Holder must pay all stamp, issue,  registration or other
         taxes and duties arising upon exercise in Switzerland or payable in any
         jurisdiction  upon the issue or  delivery  of  Shares,  if any,  to the
         exercising Holder or to the order of a person other than the exercising
         Holder.

         The date on which  these  conditions  precedent  to  exercise as stated
         above have been  verified and  recognized by the Warrant Agent as being
         fulfilled in  hereafter  called the  "Deposit  Date".  The Common Stock
         Warrant  shall be treated as  exercised at the close of business in New
         York on the Exercise  Date.  The "Exercise  Date" for the Warrant means
         the business days in New York  immediately  following the Deposit Date.
         The  "Exercise  Date" for the Common Stock  Warrant  shall not be later
         than the Termination Date.

         The Company  shall not be  obligated  to issue any  fraction of a Share
         upon the  exercise of any Warrant or make any payment for a fraction of
         a Share. If more than one Warrant shall be exercised at one time by the
         same Holder, the number of full Shares which shall be issuable upon

                                                                            3.

         exercise thereof shall be computed on the basis of the aggregate number
         of shares  issuable upon the exercise of all the Warrants  exercised by
         such  Holder.  Any Shares  issued upon the exercise of the Common Stock
         Warrants shall be delivered in accordance with the  instructions of the
         Holder.

         In the event of any exercise of the rights  represented by this Warrant
         certificates  for the shares of  Warrant  Stock so  purchased  shall be
         dated the date of such  exercise  and  delivered  to the Holder  hereof
         within a reasonable  time,  not exceeding five Business Days after such
         exercise,  and the Holder hereof shall be deemed for all purposes to be
         the Holder of the shares of Warrant  Stock so  purchased as of the date
         of such exercise.

         Neither this Warrant nor any Warrant  Stock has been  registered  under
         the Securities Act.  Accordingly,  neither this Warrant nor any Warrant
         Stock is  transferable  except as permitted  under  various  exemptions
         contained  in  the  Securities   Act,  or  upon   satisfaction  of  the
         registration  and prospectus  delivery  requirements  of the Securities
         Act.

4.       Stock Fully Paid; Reservation of Shares

         The Company covenants and agrees that all shares of Warrant Stock which
         may be issued upon the exercise of this Warrant will, upon issuance, be
         fully  paid and  non-assessable  and free  from all  taxes,  liens  and
         charges with respect to issuance.  The Company  further  covenants  and
         agrees  that  during  the  period  within  which  this  Warrant  may be
         exercised,  the Company will at all times have  authorized and reserved
         for the purpose of the issue upon exercise of the  subscription  rights
         evidenced by this Warrant a sufficient number of shares of Common Stock
         to provide for the exercise of this Warrant. If the Warrant Price is at
         any time less than the par value of the Warrant Stock or if the Warrant
         at any time is exercisable by its delivery alone and without payment of
         any additional consideration,  the Company also covenants and agrees to
         cause to be taken such action  (whether by decreasing  the par value of
         the Warrant  Stock,  the conversion of the Warrant Stock from par value
         to no par value,  or  otherwise)  as will  permit the  exercise of this
         Warrant without any additional payment by the Holder hereof (other than
         payment of the Warrant Price, if any, and applicable transfer taxes, if
         any), and the issuance of the Warrant Stock,  which Warrant Stock, upon
         such issuance, will be fully paid and non-assessable.

         The  Company  shall not by any action  including,  without  limitation,
         amending   its   certificate   of    incorporation   or   through   any
         reorganization, transfer of assets, consolidation, merger, dissolution,
         issue or sale of securities  or any other  voluntary  action,  avoid or
         seek to avoid the observance or performance of any of the terms of this
         Warrant, but will at all times in good faith assist in the carrying out
         of all such  terms  and in the  taking  if all such  actions  as may be
         necessary or  appropriate  to protect the rights of the Holders  hereof
         against  impairment.  Without limiting the generality of the foregoing,
         the Company will (a) not increase the par value of any shares of Common
         Stock  receivable  upon the exercise of this  Warrant  above the amount
         payable therefor upon such exercise  immediately prior to such increase
         in par  value,  (b)  take  all  such  action  as may  be  necessary  or
         appropriate  in order that the Company  may  validly and legally  issue
         fully paid and non-assessable shares of Common Stock, free and clear of
         any  liens,  claims,  encumbrances  and  restrictions  (other  than  as
         provided  herein)  upon the exercise of this  Warrant,  and (c) use its
         best efforts to obtain all such authorizations,  exemptions or consents
         from any public regulatory body having  jurisdiction  thereof as may be
         necessary to enable the Company to perform its  obligations  under this
         Warrant.

5.       Adjustment of Purchase Price and Number of Shares

         The number and kind of securities purchasable upon the exercise of this
         Warrant  and the  payment  of the  Warrant  Price  shall be  subject to
         adjustment  from time to time upon the  happening of certain  events as
         follows:

         a)       Recapitalization, Reorganization, Reclassification, 
                  Consolidation Merger or Sale

                  In  case  of any  recapitalization  or  reorganization  of the
                  Company  or any  reclassification  or  change  of  outstanding
                  Securities  issuable upon exercise of this Warrant (other than
                  a change in par value,  or from par value to no par value,  or
                  from no par value to par value or as a result of a subdivision
                  or combination),  or in case of any consolidation or merger of
                  the Company  with or into  another  corporation  (other than a
                  merger with  another  corporation  in which the Company is the
                  surviving  corporation  and  which  does  not  result  in  any
                  reclassification or change - other than a change in par value,
                  or from par value to no par value, or from no par value to par
                  value,  or as a result of a  subdivision  or  combination - of
                  outstanding   Securities   issuable   upon  exercise  of  this
                  Warrant),  or in  case  of any  sale or  transfer  to  another
                  corporation  of the  Property of the Company as an entirety or
                  substantially  as an entirety in connection with a liquidation
                  or dissolution  of the Company,  the Company or such successor
                  or  purchasing  corporation  therefor,  issue  a new  Warrant,
                  providing  that the  Holder(s) of this Warrant  shall have the
                  right to  exercise  such new  Warrant  and  procure  upon such
                  exercise  in lieu of each share of Warrant  Stock  theretofore
                  issuable  upon  exercise  of this  Warrant  the  kind  and the
                  highest amount of shares of Stock, other securities, money and
                  property     receivable     upon    such     recapitalization,
                  reorganization,   reclassification,   change,   consolidation,
                  merger,  sale or  transfer  by a Holder of one share of Common
                  Stock  issuable  upon  exercise  of this  Warrant  had it been
                  exercised   immediately   prior   to  such   recapitalization,
                  reorganization,   reclassification,   change,   consolidation,
                  merger sale or transfer.  Such new Warrant  shall  provide for
                  adjustments  which  shall be as  nearly  equivalent  as may be
                  practicable to the adjustments provided for in this Section 4.
                  The provisions of this subsection (a) shall similarly apply to
                  successive         recapitalizations,         reorganizations,
                  reclassifications, changes, consolidations, mergers, sales and
                  transfers.

         b)       Subdivision or Combination of Shares

                  If the Company, at any time while this Warrant is outstanding,
                  shall subdivide or combine any class or classes of its Common,
                  (i) in case of subdivision of shares,  the Warrant Price shall
                  be  proportionately  reduced (as at the effective date of such
                  subdivision  of, if the Company shall take a record of Holders
                  of its Common for the  purpose  of so  subdividing,  as at the
                  applicable  record date,  whichever is earlier) to reflect the
                  increase in the total  number of shares of Common  outstanding
                  as a  result  of such  subdivision,  or (ii) in the  case of a
                  combination   of   shares,   the   Warrant   Price   shall  be
                  proportionately  increased (as at the  effective  date of such
                  combination, or, if the Company shall take a record of Holders
                  of its  Common  for the  purpose  of so  combining,  as at the
                  applicable  record date,  whichever is earlier) to reflect the
                  reduction in the total number of shares of Common  outstanding
                  as a result of such combination.

         c)       Certain Dividends and Distributions

                  If the Company, at any time while this Warrant is outstanding,
shall:

                  (ii)     Stock Dividends

                           Pay a dividend in, or make any other distribution of,
                           shares of any class or classes of Common, the Warrant
                           Price Shall be  adjusted,  as at the date the Company
                           shall  take a record of the  holders of such class or
                           classes of Common,  for the purpose of receiving such
                           dividend or other  distribution (or if no such record
                           is  taken,  as at the date of such  payment  or other
                           distribution),    to   that   price   determined   by
                           multiplying  the Warrant Price in effect  immediately
                           prior to such  record  date (or if no such  record is
                           taken,  then  immediately  prior to such  payment  or
                           other distribution),  by a fraction (1) the numerator
                           of which  shall be the  total  number  of  shares  of
                           Common outstanding immediately prior to such dividend
                           or  distribution,  and (2) the  denominator  of which
                           shall  be  the  total  number  of  shares  of  Common
                           outstanding   immediately   after  such  dividend  or
                           distribution (plus in the event that the Company paid
                           cash for fractional  shares, the number of additional
                           shares  which  would  have been  outstanding  had the
                           Corporation  issued  fractional  shares in connection
                           with said dividends); or

                  (ii)     Liquidating Dividends, etc.

                           its Common as a dividend  in  liquidation  or partial
                           liquidation or by way of return of capital other than
                           as a dividend payable out of funds legally  available
                           for  dividends   under  the  laws  of  the  State  of
                           Delaware,  the  Holder of this  Warrant  shall,  upon
                           exercise  and  payment  of  the  Warrant  Price,   be
                           entitled  to  receive,  in  addition to the number of
                           shares of Warrant  Stock  receivable  thereupon,  and
                           without  payment  of  any  additional   consideration
                           therefor,  a sum equal to the amount of such Property
                           as would have been payable to such Holder as owner of
                           that  number  of  shares  of  Warrant  Stock  of  the

                  provided in the foregoing  subsections (a) through (c) of this
                  Section 4), at a price per share less than the  Warrant  Price
                  then in effect or less than (i) the Current  Market Price then
                  in effect is such issue is pursuant to a public  offering,  or
                  (ii) ninety five  percent  (95%) of the Current  Market  Price

                  without  consideration,  then the Warrant Price upon each such
                  issuance  shall  be  adjusted  to  that  price  determined  by
                  multiplying the Warrant Price by a fraction:

                  (A)      If issued for a consideration per share less than (i)
                           the Current Market Price then in effect if such issue
                           is pursuant to a public offering, or (ii) ninety five
                           percent  (95%) of the  Current  Market  Price then in
                           effect  if  such  issue  is  pursuant  to  a  private
                           placement in excess of $ 3'500'000 in the  aggregate,
                           or for no consideration:

                           1)       the  numerator  of which shall be the number
                                    of shares of Common outstanding  immediately
                                    prior  to the  issuance  of such  Additional
                                    Shares of Common  plus the  number of shares
                                    of Common which the aggregate  consideration
                                    for the  total  number  of  such  Additional
                                    Shares of Common so issued would purchase at
                                    (i) the Current  Market Price then in effect
                                    if  such  issue  is  pursuant  to  a  public
                                    offering,  or (ii) ninety five percent (95%)
                                    of the Current  Market  Price then in effect
                                    if  such  issue  is  pursuant  to a  private
                                    placement  in excess of $  3'500'000  in the
                                    aggregate, and

                           2)       the denominator of which shall be the number
                                    of shares of Common outstanding immediately 
                                    after the issuance of such Additional Shares
                                    of Common.

                  (B)      If issued for a consideration per share less than the
                           Warrant Price or for no consideration:

                           1)       the  numerator  of which shall be the number
                                    of shares of Common outstanding  immediately
                                    prior  to the  issuance  of such  Additional
                                    Shares of Common  plus the  number of shares

                                    for the  total  number  of  such  Additional
                                    Shares of Common so issued would purchase at
                                    the Warrant Price, and

                           2)       the denominator of which shall be the number
                                    of shares of Common outstanding immediately
                                    after the issuance of such Additional Shares
                                    of Common.

                           If such  Additional  Shares of Common shall be issued
                           at a price per share less than both the Warrant Price
                           and the Current Market Price, the Warrant Price shall
                           be adjusted in the manner  provided in clauses (i) or
                           (ii) of this  subsection (d) which will result in the
                           greater reduction in the amount of the Warrant Price.

                           The provisions of this subsection (d) shall not apply
                           under   any  of  the   circumstances   for  which  an
                           adjustment is provided in subsections (a), (b) or (c)
                           of this Section 5. No adjustment of the Warrant Price
                           shall  be made  under  this  subsection  (d) upon the
                           issuance of any Additional Shares of Common which are
                           issued  pursuant to any Common  Stock  Equivalent  if
                           upon the issuance of such Common Stock Equivalent (1)
                           any  adjustment  shall  have  been made  pursuant  to
                           subsection (e) of this Section 5 or (2) no adjustment
                           was  required  pursuant  to  subsection  (e) of  this
                           Section 5.

                  e)       Issuance of Common Stock Equivalents

                           In case the  Company  shall at any  time  while  this
                           Warrant  is  outstanding,   issue  any  Common  Stock
                           Equivalent   and  the   price  per  share  for  which
                           Additional   Shares   of  Common   may  be   issuable
                           thereafter  pursuant to such Common Stock  Equivalent
                           shall be less than the  Warrant  Price then in effect
                           on  the  date  of  issuance  of  such  Common   Stock
                           Equivalent or less than (i) the Current  Market Price
                           then in effect if such issue is  pursuant to a public
                           offering,  or (ii) ninety five  percent  (95%) of the
                           Current  Market Price then in effect if such issue is
                           pursuant  to  a  private  placement  in  excess  of $
                           3'500'000  in the  aggregate,  or if,  after any such
                           issuance of Common Stock  Equivalents,  the price per
                           share for which  Additional  Shares of Common  may be
                           issuable  thereafter  is  amended  (other  than  as a
                           result of the operation of  anti-dilution  provisions
                           of  or   relating   to   Common   Stock   Equivalents
                           outstanding as of the date hereof  pursuant to events
                           or  circumstances  which  would  also  result  in  an
                           adjustment in the Warrant  Price),  and such price as
                           so amended  shall be less than the  Warrant  Price or
                           the  Current  Market  Price in  effect at the time of
                           such amendment, then the Warrant Price upon each such
                           issuance or  amendment  shall be adjusted as provided
                           in the  first  sentence  of  subsection  (d) of  this
                           Section 4 on the basis that (1) the maximum number of
                           Additional  Shares of Common issuable pursuant to all
                           such Common Stock Equivalents shall be deemed to have
                           been  issued   (whether  or  not  such  Common  Stock
                           Equivalents    are   actually    then    exercisable,
                           convertible or  exchangeable  in whole or in part) as
                           of the  earlier of (A) the date on which the  Company
                           shall enter into a firm  contract for the issuance of
                           such  Common  Stock  Equivalent,  or (B) the  date of
                           actual issuance of such Common Stock Equivalent,  and
                           (2) the  aggregate  consideration  for  such  maximum
                           number of Additional Shares of Common shall be deemed
                           to  be  the  minimum   consideration   received   and
                           receivable  by the Company  for the  issuance of such
                           Additional  Shares of Common  pursuant to such Common
                           Stock Equivalent.  No adjustment of the Warrant Price
                           shall  be made  under  this  subsection  (e) upon the
                           issuance of any Convertible  Security which is issued
                           pursuant  to the  exercise  of any  warrants or other
                           subscription  or  purchase  rights  therefor,  if any
                           adjustment  shall  previously  have  been made in the
                           Warrant  Price then in effect  upon the  issuance  of
                           such  warrants  or  other  rights  pursuant  to  this
                           subsection (e).

                  f)       Other Provisions Applicable to Adjustments Under this
                           Section A

                           The following  provisions  shall be applicable to the
                           making   of   adjustments   in  the   Warrant   Price
                           hereinbefore provided in this Section 5:

                                    The  consideration  received  by the Company
                                    shall be deemed to be the following:  (a) to
                                    the  extent  that any  Additional  Shares of
                                    Common or any Common Stock Equivalents shall
                                    be  issued  for a  cash  consideration,  the
                                    consideration   received   by  the   Company
                                    therefor,  or, (b) if such Additional Shares
                                    of Common or Common  Stock  Equivalents  are
                                    offered by the Company for subscription, the
                                    subscription price, or, (c) if such

                                    Additional  Shares of Common or Common Stock
                                    Equivalents  are  sold  to  underwriters  or
                                    dealers  for  public   offering   without  a

                                    offering  price,  in any such case excluding
                                    any amounts paid or  receivable  for accrued
                                    interest  or accrued  dividends  and without
                                    deduction  of any  compensation,  discounts,
                                    commissions, or expenses paid or incurred by
                                    the  Company for or in  connection  with the

                                    the extent that such issuance shall be for a
                                    consideration  other than cash, then, except
                                    as herein otherwise expressly provided,  the
                                    fair market value of such  consideration  at
                                    the time of such  issuance as  determined in
                                    good faith by the Board.  The  consideration

                                    such Common  Stock  Equivalents.  In case of
                                    the  issuance at any time of any  Additional
                                    Shares of Common or Common Stock Equivalents

                                    the  Corporation  shall  be  deemed  to have
                                    received  for  such  Additional   Shares  of
                                    Common  or  Common   Stock   Equivalents   a
                                    consideration  equal  to the  mount  of such
                                    dividend so paid or  satisfied.  In any case
                                    in which the consideration to be received or
                                    paid  shall be other  than  cash,  the Board
                                    shall  notify  the  Holder  of this  Warrant
                                    through    Banca   del   Gottardo   of   its
                                    determination  of the fair  market  value of
                                    such  consideration   prior  to  payment  or
                                    accepting receipt thereof.  If within thirty
                                    days  after  receipt  of  said  notice,  the
                                    Holders of Warrants exercisable for at least
                                    a majority  of Warrant  Stock then  unissued
                                    shall  notify  the Board in writing of their
                                    objection   to   such    determination,    a
                                    determination  of fair market  value of such
                                    consideration  shall be made by  arbitration
                                    in accordance with the Rules of the American
                                    Arbitration Association, by an arbitrator in
                                    the Borough of Manhattan,  City of New York,
                                    State of New York.

                           (ii)     Readjustment of Warrant Price

                                    Upon the expiration of the right to convert,
                                    exchange  or  exercise   any  Common   Stock
                                    Equivalent the issuance of which effected an
                                    adjustment  in the  Warrant  Price,  if such
                                    Common Stock  Equivalent shall not have been
                                    converted,   exercised  or  exchanged,   the
                                    number of shares of Common  Stock  deemed to
                                    be issued and  outstanding  by reason of the
                                    fact   that   they   were    issuable   upon
                                    conversion, exchange or exercise of any such
                                    Common Stock  Equivalent  shall no longer be
                                    computed as set forth above, and the Warrant
                                    Price  shall  forthwith  be  readjusted  and
                                    thereafter  be the price which it would have
                                    been (but  reflecting any other  adjustments
                                    in the  Warrant  Price made  pursuant to the
                                    provisions  of  this  Section  5  after  the
                                    issuance  of such Common  Stock  Equivalent)
                                    had the adjustment of the Warrant Price been
                                    made in accordance with the issuance or sale
                                    of the number of Additional Shares of Common
                                    actually issued upon conversion, exchange or
                                    issuance of such Common Stock

                                    Equivalent  and thereupon only the number of
                                    Additional  Shares  of  Common  actually  so
                                    issued  shall be deemed to have been  issued
                                    and only the consideration actually received
                                    by the Company (computed as in clause (i) of
                                    this subsection (g)) shall be deemed to have
                                    been received by the Company.

                           (iii)    Treasury Shares

                                    The  number  of shares of Common at any time
                                    outstanding  shall not  include  any  shares
                                    thereof then directly or indirectly owned or
                                    held by or for the account of the Company or
                                    any of its Subsidiaries.

                  g)       Other Action Affecting Common

                           In case after the date hereof the Company  shall take
                           any action affecting its common, other than an action
                           described  in any of the  foregoing  subsections  (a)
                           through  (f) of this  Section 5,  inclusive,  and the
                           failure  to make any  adjustment  would  not  failure
                           protect  the  purchase  rights  represented  by  this
                           Warrant in accordance  with the essential  intent and
                           principle of this  Section 5, then the Warrant  Price
                           shall be  adjusted in such manner and at such time as
                           the Board may in good faith determine to be equitable
                           in the circumstances.

                  h)       Adjustment of Number of Shares

                           Upon each adjustment in the Warrant Price pursuant to
                           any provision of this Section 5, the number of shares
                           of  Warrant  Stock  purchasable  hereunder  shall  be
                           adjusted,  to the nearest whole share, to the product
                           obtained  by   multiplying   such  number  of  shares
                           purchasable  immediately  prior to such adjustment in
                           the Warrant  Price by a fraction,  the  numerator  of
                           which shall be the Warrant Price immediately prior to
                           such adjustment and the denominator of which shall be
                           the  Warrant  Price  immediately  thereafter.  If the
                           Company  shall  be in  default  under  any  provision
                           contained  in the last  sentence of Section 5 of this
                           Warrant so that shares  issued at the  Warrant  price
                           adjusted in accordance  with this Section 5 would not
                           be validly issued, the adjustment of number of shares
                           provided  for  in  the   foregoing   sentence   shall
                           nonetheless  be made and the  Holder of this  Warrant
                           shall be entitled to purchase such greater  number of
                           shares at the lowest  price at which such  shares may
                           then be validly  issued under  applicable  law.  Such
                           exercise  shall not  constitute a waiver of any claim
                           arising  against the Company by reason of its default
                           under Section 5 of this Warrant.

                           i) Notwithstanding  anything in this Section 5 to the
                           contrary,  neither  the  number of shares of  Warrant
                           Stock  purchasable  hereunder  nor the Warrant  Price
                           shall be adjusted  with  respect to any Common  Stock
                           Equivalents  issued and outstanding as of the date of
                           the issuance of this Warrant,  or the issuance of any
                           Securities  upon  exercise or  conversion of any such
                           Common   Stock   Equivalent,    including,    without
                           limitation,  any Securities  issued from time to time
                           pursuant to (i) the  exercise of options  outstanding
                           as of the date of issuance of the Warrant and held by
                           present or former directors, officers or employees of
                           the Company, (ii) the

                  in the domestic  over-the-counter  market,  the Current Market
                  Price shall be deemed to be an amount  mutually agreed upon in
                  writing between the Corporation and the Holder of this Warrant
                  within  fifteen days  immediately  following the date on which
                  the Current Market Price is to be determined.  If no agreement
                  as to Current Market Price is determined as stated herein, (i)
                  the  Holder  of  this  Warrant  shall  select  an  independent
                  appraiser who shall  determine the fair market value per share
                  of the  Common  which  shall  be  the  Current  Market  Price,
                  provided the Company shall agree to such Current Market Price.
                  If the Company shall not agree to the Current  Market Price as
                  determined in the preceding sentence then (ii) the Company and
                  Banca del Gottardo shall each select an independent  appraiser
                  who shall, independently of the other appraiser, determine the
                  fair market value of the Common of the  Company.  If the value
                  determined by the appraiser whose  determination is the higher
                  of the two appraisals does not exceed by more than ten percent
                  (10%) the average of the values  determined by each appraiser,
                  then the  Current  Market  Price  shall be the  average of the
                  values  determined  by  the  two  appraisers.   If  the  value
                  determined by the appraiser whose  determination is the higher
                  of the two  appraisals  does  exceed by more than ten  percent
                  (10%) the average of the value  determined by each  appraiser,
                  then  the two  appraisers  shall  select  a third  independent
                  appraiser who shall,  independently  of the other  appraisals,
                  determine  the fair  market  value of the  Common.  The  value
                  determined by the appraiser  whose  determination  is the most
                  discrepant from the average of the three  appraisals  shall be
                  discarded,  and the  Current  Market  Price  shall  equal  the
                  average of the  remaining two  appraisals;  except that in the
                  event that the  highest  and  lowest  appraisals  are  equally
                  discrepant  from the  average  of the  three  appraisals,  the
                  Current Market Price shall be such average.  The Company shall
                  bear the expenses of all appraisals.

                  "Governmental  Body" shall mean any  federal,  state,  county,

                  Warrants are outstanding it will maintain an agent for service
                  of process in  Switzerland.  The  aforementioned  jurisdiction
                  shall also be valid for the  cancellation  and  replacement of
