                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  JUNE 30, 1997
                                   (UNAUDITED)




1.   CONSOLIDATED FINANCIAL STATEMENTS

     The  accompanying  consolidated  balance  sheets  as of June  30,  1997 and
     December  31,  1996  and  the  accompanying   consolidated   statements  of
     operations  and cash flows for the three and six months ended June 30, 1997
     and 1996 and for the period from October 17, 1986  (inception)  to June 30,
     1997,   have  been  prepared  by  Sheffield   Pharmaceuticals,   Inc.  (the
     "Company"),  without audit.  In the opinion of management,  all adjustments
     (consisting only of normal recurring  accruals) necessary to present fairly
     the financial position,  results of operations,  and cash flows at June 30,
     1997 and for all periods presented have been made.

     Certain information and footnote disclosures normally included in financial
     statements  prepared  in  accordance  with  generally  accepted  accounting
     principles  have been  condensed  or omitted.  It is  suggested  that these
     consolidated financial statements be read in conjunction with the financial
     statements  and notes thereto  included in the  Company's  annual report on
     Form 10-KSB for the year ended December 31, 1996. The results of operations
     for the  three  and six  months  ended  June  30,  1997  and  1996  are not
     necessarily indicative of the operating results for the full years.

     The Company was incorporated on October 17, 1986, under the Canada Business
     Corporations  Act. The Company's  wholly-owned  subsidiary,  U-Tech Medical
     Corporation  ("U-Tech") was  incorporated  in the state of Texas on January
     13, 1992 and has been  substantially  inactive for two years as of June 30,
     1997.  On July 30, 1997 U-Tech was  dissolved.  On January  10,  1996,  Ion
     Pharmaceuticals,  Inc.,  a Delaware  corporation  ("Ion"),  was formed as a
     wholly-owned  subsidiary  of the  Company.  At that time,  Ion acquired the
     Company's  rights with  respect to its  anti-proliferative  technology.  On
     April 17, 1997, CP Pharmaceuticals,  Inc. ("CP") was formed for the purpose
     of acquiring Camelot Pharmacal,  L.L.C.,  which acquisition was consummated
     on April 25, 1997. Unless the context requires otherwise, Sheffield, U-Tech
     , Ion and CP are referred to as "the  Company".  The Company  commenced its
     biotechnology  operations  in the United  States in January  1992 under new
     management and Sheffield  became  domesticated as a Wyoming  corporation in
     May 1992.  At the Annual  Meeting of  shareholders  of the Company  held on
     January 26,  1995,  the  Company's  shareholders  approved  the proposal to
     reincorporate the Company in Delaware, which was effected on June 13, 1995.
     All significant intercompany  transactions are eliminated in consolidation.
     At the Annual Meeting of shareholders of the Company held on June 26, 1997,
     the Company's  shareholders approved the proposal to change the name of the
     Company  from   "Sheffield   Medical   Technologies   Inc."  to  "Sheffield
     Pharmaceuticals, Inc."

     The Company is in the  development  stage and as such has been  principally
     engaged in  licensing  and  research  efforts.  The Company  has  generated
     minimal  operating  revenue  and  requires  additional  capital,  which the
     Company  intends to obtain through equity and debt offerings to continue to
     operate its business. The Company's ability to meet its obligations as they
     become due and to continue as a going  concern must be  considered in light
     of the expenses, difficulties and delays frequently encountered in starting
     a new  business,  particularly  since the Company  will focus on  research,
     development and unproven  technology  which may require a lengthy period of
     time and substantial  expenditures to complete. Even if the Company is able
     to  successfully  develop  new  products or  technologies,  there can be no
     assurance  the Company will generate  sufficient  revenues from the sale or
     licensing of such products and  technologies  to be profitable.  Management
     believes that the Company's  ability to meet its obligations as they become
     due and to continue as a going concern through  December 1997 are dependent
     upon obtaining additional financing.

2.   NET LOSS PER COMMON SHARE

     Net loss per  common  share  is based on net loss for the  relevant  period
     divided by the weighted  average  number of shares  issued and  outstanding
     during the period. Stock options,  common stock issuable upon conversion of
     warrants  and common  stock  issuable  upon the  conversion  of  cumulative
     convertible  redeemable  preferred  stock are not reflected as their effect
     would be antidilutive for both primary and fully diluted earnings per share
     computations.

     In February 1997, the Financial Accounting Standards Board issued Statement
     No. 128,  EARNINGS  PER SHARE,  which is required to be adopted on December
     31, 1997.  At that time,  the Company will be required to change the method
     currently  used to  compute  earnings  per share and to  restate  all prior
     periods.  The impact of  Statement  128 on the  calculation  of primary and
     fully diluted earnings per share is not expected to be material.



3.   SUPPLY AND LICENSE AGREEMENTS

     In March 1997, the Company  exercised its option and entered into exclusive
     supply and license  agreements for the world-wide  rights to the multi-dose
     inhaler technology (MSI) of Siemens A.G. The agreements call for Siemens to
     be the  exclusive  supplier  of  the  MSI  system,  a  hand-held,  portable
     pulmonary delivery system. The Company paid a licensing fee of $1.1 million
     in April 1997 to Siemens pursuant to its agreements and is required to make
     additional  payments  to Siemens  of DM 2.0  million on January 1, 1998 and
     1999.



4.   ACQUISITION

     On April 25, 1997, the Company acquired Camelot  Pharmacal,  L.L.C., of St.
     Louis,  Missouri,  a privately held emerging  pharmaceutical  company.  The
     members of Camelot's  management  team have been appointed  officers of the
     Company and Loren G. Peterson, a principal of Camelot, has been named Chief
     Executive  Officer of the  Company  and has joined the  Company's  Board of
     Directors. Consideration for this transaction was 600,000 shares of Company
     common stock. In addition,  the members of the Camelot management team have
     been granted  options to acquire 1.2 million  common shares  exercisable at
     market price as of the date of grant.

ITEM 2:

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS



The Company,  being a development stage  enterprise,  has incurred a net loss in
each of the  fiscal  years  since its  inception  and has had to rely on outside
sources of funds to maintain its  liquidity.  Substantial  operating  losses are
expected to be incurred  for the next several  years as the Company  expends its
resources for product acquisition,  research and development and preclinical and
clinical testing.

As a development  stage company without  significant  revenues,  the Company has
financed its technology  development activities and operations primarily through
public  and  private  offerings  of  securities,  from  which it has  raised  an
aggregate of approximately  $28.4 million through June 30, 1997. On February 28,
1997, the Company completed a private offering of 35,000 shares of its 7% Series
A Cumulative  Convertible  Redeemable  Preferred Stock, which raised total gross
proceeds of $3.5  million.  The proceeds of this offering are to be used to fund
research and development, patent prosecution and for working capital and general
corporate purposes.  Such proceeds may also be used for the possible acquisition
of rights in new technologies in the Company's ordinary course of business.  The
Company's  operating results have fluctuated  significantly  during each quarter
since its inception, and the Company anticipates that such fluctuations, largely
attributable  to varying  sponsored  research and  development  commitments  and
expenditures, will continue into the foreseeable future.

The  Company  continues  to  conduct  scientific   research,   clinical  trials,
development, and intellectual property protection. During the three months ended
June 30, 1997, the Company funded  $786,165 for research and  development on its
projects.  During the succeeding 12-month period,  approximately $8.3 million in
additional  funding is  projected  to be  incurred on  clinical  and  laboratory
research  and   development.   Of  this  estimated   funding  of  $8.3  million,
approximately  $7,500,000 is expected to be applied to the MSI,  $675,000 to the
Ion Pharmaceuticals  Technologies,  $25,000 to the HIV/AIDS Vaccines, $40,000 to
the UGIF Technology-Prostate  Cancer, and $60,000 to the Membrane Attack Complex
(MAC)/Complement Technology.

In addition to clinical and laboratory research development, the Company expects
to incur ongoing costs in connection with its intellectual  property  protection
and patent  prosecution,  which costs are expected to approximate  $100,000 over
the next 12 months.

REVENUES AND EXPENSES

Revenues:

From  inception  through the period ended June 30, 1997,  the Company has earned
sub-license revenue of $510,000 primarily from the sub-license agreement for its
liposome-CD4 technology.

From  inception  through the period ended June 30, 1997,  the Company has earned
interest  income  of  $436,885  and an  extraordinary  item  from  gain on early
extinguishment  of debt of $42,787.  The Company's  ability to generate material
revenues is contingent on the successful  commercialization its technologies and
other  technologies which it may acquire,  followed by the successful  marketing
and  commercialization of such technologies through licenses,  joint ventures or
other arrangements.

Interest income for the three months ended June 30, 1997 was $21,747 compared to
$52,724 for the same period ended June 30, 1996. The decrease in interest earned
is attributable to a decrease of cash invested in short-term  investments Except
for the sub-license revenue mentioned above,  interest income represented all of
the Company's income in each of the prior periods.

Operating Expenses:

From  inception  through the period  ended June 30, 1997,  the Company  incurred
$33,667,811  of operating  expenses.  Of the total  operating  expenses for that
period,  $18,247,399  were costs of research and  development  for the Company's
technologies and $1,650,000 for the acquisition of R & D in-process  technology.
The  remainder  of expenses  for the same period were  incurred  principally  as
consulting  costs,  costs of management,  legal and other  professional fees and
expenses  relating to the  Company's  technologies,  and for its  completed  and
proposed financing plans.  Research and development costs are expected to remain
high as the Company implements later-stage research projects of its technologies
and such costs will continue to be expensed for financial reporting purposes.

Operating  expenses for the three months  ended June 30, 1997,  were  $3,443,146
compared to $1,710,681  for the same period ended June 30, 1996. The increase in
operating  expenses was  primarily  due to the  acquisition  of R & D in-process
technology,  in the  amount of  $1,650,000,  as a result of the  acquisition  of
Camelot   Pharmacal,   L.L.C.  in  April  1997.  The  increase  in  general  and
administrative  expenses  was  primarily  due to increased  salary  expense as a
result of the additions to the Company's management team and higher professional
fees.  The major items included in general and  administrative  expenses for the
three months ended June 30, 1997,  were (i) salaries of $320,174 which increased
by $111,669 as compared to 1996, primarily due to the increase in management and
staff,  (ii)  professional  fees of $262,005  or  $167,061  higher than the same
period in 1996,  primarily  due to increased  patent and  financing  activities,
(iii)  consulting  fees of $131,952  or $29,996  higher than 1996 and (iv) other
expenses of $290,761.

The table below  indicates (i) the  Company's  direct  research and  development
expenses  by  project  for the six  months  ended  June  30,  1997  and from the
Company's  inception to June 30, 1997,  (ii) the Company's  current  estimate by
project of committed and/or anticipated funding requirements after June 30, 1997
and (iii) revenues received to date by project.

LIQUIDITY AND CAPITAL RESOURCES

On February 28, 1997, the Company  completed a private offering of 35,000 shares
of its 7% Series A Cumulative  Convertible  Redeemable  Preferred  Stock,  which
raised total gross  proceeds of $3.5 million.  The proceeds of this offering are
being used to fund research and development,  patent prosecution and for working
capital and general corporate  purposes.  Such proceeds may also be used for the
possible  acquisition of rights in new  technologies  in the Company's  ordinary
course of business.

In March 1997,  the Company  exercised  its option and  entered  into  exclusive
supply and license  agreements for the world-wide rights to Siemens'  multi-dose
inhaler (MSI).  The agreements call for Siemens to be the exclusive  supplier of
the MSI system,  a hand-held,  portable  pulmonary  drug  delivery  system.  The
Company paid Siemens a license fee of $1.1 million in April 1997 pursuant to the
agreements  and is  required  to make  additional  payments of DM 2.0 million on
January 1, 1998 and 1999.

The Company has  historically  financed its operations  through public offerings
and  private  placements  of  its  securities.  In  addition  to  the  potential
commercialization  of its  technologies,  the Company  plans to seek  additional
funds  through  bridge  loans,  security  financings,  joint  ventures  or other
commercial arrangements to obtain necessary working capital. It is not uncommon,
for  instance,  for a  third-party  commercial  partner  to enter into a license
agreement  with a technology  development  company,  on the merits of successful
research  relating to a given  technology,  which would yield  up-front  royalty
advances to such company before market-ready products are developed.  It is also
not uncommon  for a  third-party  commercial  partner to enter into an agreement
with a  development  company  whereby a third  party  will  contribute  funds in
support of the research and  operating  needs of such  development  companies in
consideration for rights related to the technologies.

The Company's ability to continue its operations as planned will be dependent on
the  Company's  ability to obtain  additional  funds,  particularly  through the
public  offering  and/or  private  placement of its  securities.  The Company is
currently  involved in negotiations  with  interested  parties over the terms of
proposed financings. However, there can be no assurance that any such financings
will  actually be  consummated.  In the event that proposed  financings  are not
completed,  there can be no assurance  that other  sources of capital may become
available in amounts and upon terms  acceptable  to the Company.  The failure by
the  Company to obtain  such funds will  require  the  Company to  significantly
reduce or delay its funding of current  technology  development  projects (which
may result in the  Company's  loss of rights in the  related  technologies)  and
delay the making of commitments for future projects.

                           the affairs of the Corporation shall be vested in its
                           Board of  Directors.  The number of  directors  which
                           shall  constitute the whole Board of Directors  shall
                           be  fixed  by,  or in the  manner  provided  in,  the

                           were no vacancies.  No election of directors  need be
                           by written ballot.

                           2.  After  the  original  or  other  By-laws  of  the
                           Corporation have been adopted,  amended, or repealed,
                           as the case may be, in accordance with the provisions
                           of ss.109 of the General Corporation Law of the State
                           of Delaware,  and, after the Corporation has received
                           any payment for any of its stock, the power to adopt,
                           amend,  or repeal the By-laws of the  Corporation may
                           be  exercised  by  the  Board  of  Directors  of  the
                           Corporation;  provided,  however,  that any provision
                           for   the   classification   of   directors   of  the
                           Corporation  for  staggered  terms  pursuant  to  the
                           provisions of subsection (d) of ss.141 of the General
                           Corporation Law of the State of Delaware shall be set
                           forth in an initial By-law or

                           classification shall be set forth in this Certificate
                           of Incorporation.

                           3.  Whenever the  Corporation  shall be authorized to
                           issue only one class of stock, each outstanding share
                           shall  entitle  the holder  thereof to notice of, and
                           the right to vote at, any  meeting  of  stockholders.
                           Whenever the Corporation shall be authorized to issue
                           more than one class of stock, no outstanding share of
                           any class of stock which is denied voting power under
                           the provisions of the  Certificate  of  Incorporation
                           shall entitle the holder thereof to the right to vote
                           at  any  meeting  of   stockholders   except  as  the
                           provisions  of  paragraph  (2) of  subsection  (b) of
                           ss.242 of the General Corporation Law of the State of
                           Delaware shall otherwise require;  provided,  that no
                           share of any such  class  which is  otherwise  denied
                           voting power shall entitle the holder thereof to vote
                           upon  the  increase  or  decrease  in the  number  of
                           authorized shares of said class.

                  NINTH:  The  personal   liability  of  the  directors  of  the
Corporation is hereby  eliminated to the fullest  extent  permitted by paragraph
(7) of subsection (b) of ss.102 of the General  Corporation  Law of the State of
Delaware, as same may be amended and supplemented.

have power to  indemnify  under said section from and against any and all of the
expenses,  liabilities  or  other  matters  referred  to in or  covered  by said
section,  and the  indemnification  provided  for  herein  shall  not be  deemed
exclusive of any other rights to which those  indemnified  may be entitled under
any By-Law,  agreement,  vote of  stockholders  or  disinterested  directors  or
otherwise,  both as to  action  in his  official  capacity  and as to  action in
another  capacity  while holding such office,  and shall continue as to a person
who has ceased to be a director,  officer,  employee or agent and shall inure to
the benefit of the heirs, executors and administrators of such a person.

                  ELEVENTH:  From  time to time  any of the  provisions  of this
Certificate  of  Incorporation  may be amended,  altered or repealed,  and other
provisions  authorized by the laws of the State of Delaware at the time in force

other  series to the  extent  permitted  by law.  Except as  expressly  provided
elsewhere in this Article  FOURTH no vote of the holders of the Preferred  Stock
or Common  Stock shall be required in  connection  with the  designation  or the
issuance of any shares of any series of any  Preferred  Stock  authorized by and
complying  with the  conditions  herein,  the  right  to have  such  vote  being

been  paid,  as the  case  may  be,  on the  Series  A  Preferred  Stock  by the
Corporation.  Subject to, and as provided in, Section 4, the  Corporation  shall
pay all  cumulative  stock  dividends on the shares of Series A Preferred  Stock
held by a holder on the  Conversion  Date (as defined  below) in respect of such
holder's  election to convert Series A Preferred  Stock. The number of shares of
Common Stock to be issued as cumulative  stock  dividends on any such Conversion
Date shall  equal the cash  value of such  cumulative  dividends  divided by the
current  market  price per share of Common  Stock  (determined  as  provided  in
Section 5) as of such Conversion Date. The cash value of stock dividends payable
on shares of Series A Preferred  Stock for any full annual dividend period shall
be computed by  multiplying  the original  $100.00  purchase  price per share by
7.0%.  The cash value of  dividends  payable on shares of the Series A Preferred
Stock for any period less than a full annual  dividend  period shall be computed
on the basis of a 360-day year of twelve  30-day months and the actual number of
days elapsed in the period for which payable.

                           If stock dividends are not paid in full, or declared
in full, upon the shares of the Series A Preferred Stock and shares of any other
preferred  stock ranking on a parity as to payment of stock  dividends  with the
Series A Preferred  Stock,  all  dividends  declared upon shares of the Series A
Preferred  Stock and any other preferred stock ranking on a parity as to payment
of  dividends  with the Series A Preferred  Stock shall be paid or declared  PRO
RATA so that in all cases the amount of dividends  paid or declared per share on
the Series A Preferred Stock and such other shares of preferred stock ranking on
a parity as to payment of dividends with the Series A Preferred Stock shall bear
to each  other the same  ratio  that  accumulated  stock  dividends  per  share,
including dividends accrued or in arrears, if any, on the shares of the Series A
Preferred  Stock and such other  shares of  preferred  stock bear to each other.
Except as provided in the  preceding  sentence,  unless  full  cumulative  stock
dividends  on the  shares  of the  Series A  Preferred  Stock  have been paid or
declared in full, no dividends  (other than dividends in shares of Common Stock,
or in shares of any other capital stock of the Corporation ranking junior to the
Series A Preferred  Stock as to payment of dividends and  distribution of assets
upon  liquidation)  shall be paid or declared and set aside for payment or other
distribution  upon the Common Stock or, except as provided  above,  on any other
capital  stock of the  Corporation  ranking  junior  to or on a parity  with the
Series A Preferred  Stock as to dividends,  nor shall any shares of Common Stock
or shares of any other capital stock of the Corporation  ranking junior to or on
a parity  with the  Series  A  Preferred  Stock  as to  dividends  be  redeemed,
purchased or otherwise acquired for any consideration (or any payment made to or
available  for a sinking  fund for the  redemption  of any such  shares)  by the
Corporation or any subsidiary of the  Corporation  (except by conversion into or
exchange for shares of capital stock of the

                                       -2-
<PAGE>
Corporation  ranking junior to the Series A Preferred  Stock as to dividends and
distribution  of assets  upon  liquidation).  Holders  of shares of the Series A
Preferred  Stock  shall not be  entitled to any  dividends,  whether  payable in
capital stock, cash or property,  in excess of full accrued and cumulative stock
dividends  as herein  provided.  No interest or sum of money in lieu of interest
shall be payable in respect of any stock  dividend  payment or  payments  on the
shares  of the  Series  A  Preferred  Stock  that may be in  arrears;  provided,
however,  that if, on an applicable  Conversion Date (as defined herein),  stock
dividends  that would have been  payable on such date are not paid solely due to
the failure of the  Corporation's  Board of Directors to declare such dividends,
then the rate of conversion  of the Series A Preferred  Stock to be converted on
such  Conversion  Date shall be adjusted so that the holders  would  receive the
same amount of shares of Common Stock on such  Conversation  Date as such holder
would have received if the Corporation's  Board of Directors had timely declared
such stock dividends.

                  The  terms  "accrued   dividends,"   "dividends  accrued"  and
"dividends  in  arrears,"  whenever  used  herein  with  reference  to shares of
preferred  stock  shall be  deemed  to mean an  amount  which  shall be equal to
dividends  thereon at the  applicable  annual  dividend  rates per share for the
respective  series  thereof  from the date or  dates  on  which  such  dividends
commence  to  accrue  to the  applicable  payment  date  less the  amount of all
dividends paid, or declared in full and sums set aside for the payment  thereof,
upon such shares of preferred stock.

                  Section 3.                LIQUIDATION RIGHTS.

                  (a) In the event of any liquidation, dissolution or winding up
of the affairs of the Corporation, whether voluntary or otherwise, after payment
or provision for payment of the debts and other  liabilities of the Corporation,
the  holders of shares of the Series A  Preferred  Stock  shall be  entitled  to
receive,  in cash, out of the remaining net assets of the  Corporation  (whether
from capital or from earnings  available for distribution to shareholders),  the
amount of One Hundred Dollars ($100.00) for each share of the Series A Preferred
Stock,  plus the cash value determined in accordance with Section 2 above of all
stock dividends  accrued and unpaid at the applicable rate on each such share up
to the date fixed for distribution, before any distribution shall be made to the
holders of shares of Common Stock or any other capital stock of the  Corporation
ranking (as to any such distribution) junior to the Series A Preferred Stock. If
upon any liquidation,  dissolution or winding up of the Corporation,  the assets
distributable  among the holders of shares of the Series A  Preferred  Stock and
all  other  classes  and  series  of  preferred  stock  ranking  (as to any such
distribution)  on a parity with the Series A Preferred Stock are insufficient to
permit the payment in full to the holders of all such shares of all preferential
amounts  payable to all such holders,  then the entire assets of the Corporation
thus distributable  shall be distributed ratably among the holders of the shares
of the Series A Preferred Stock and such other classes and

                                       -3-
<PAGE>
series of preferred stock ranking (as to any such distribution) on a parity with
the Series A Preferred Stock in proportion to the respective  amounts that would
be payable per share if such assets were sufficient to permit payment in full.

                  (b) For purposes of this Section 3, a  distribution  of assets
in any  dissolution,  winding  up or  liquidation  shall  not  include  (i)  any
consolidation or merger of the Corporation with or into any other corporation or
other entity, (ii) any dissolution, liquidation, winding up or reorganization of
the Corporation  immediately  followed by reincorporation of another corporation
or other entity or (iii) a sale or other disposition of all or substantially all
of the Corporation's  assets to another  corporation or other entity;  PROVIDED,
HOWEVER,  that, in each case,  effective provision is made in the certificate of
incorporation  of the resulting and surviving  corporation  or otherwise for the
protection  of the  relative  rights of the  holders  of shares of the  Series A
Preferred Stock.

                  (c)  After  the  payment  of  the  full  preferential  amounts
provided for herein to the holders of shares of the Series A Preferred  Stock or
funds  necessary  for such  payment have been set aside in trust for the holders
thereof,  such holders shall be entitled to no other or further participation in
the distribution of the assets of the Corporation.


                  Section 4.  CONVERSION AND REDEMPTION OF SERIES A
                              PREFERRED STOCK.

                  (a) Each  holder of Series A  Preferred  Stock  shall have the
right,  exercisable  at any  time  and  from  time to  time  during  the  period
commencing  on the date that is  ninety  (90) days  after the  Closing  Date and
ending on the date that is two years  after  the  Closing  Date (the  "Mandatory
Conversion  Date"),  to convert any or all of the Series A Preferred Stock owned
by such holder for shares of Common Stock,  at a conversion  rate  determined by
multiplying  the number of shares of Series A Preferred Stock to be converted by
a  fraction,  the  numerator  of which  shall  equal one  hundred  (100) and the
denominator of which (a "Denominator")  shall equal (i) the current market price
per share of the Common  Stock  (determined  as provided in Section 5) as of the
Closing Date (such current market price being referred to herein as the "Closing
Price"),  if the  applicable  Conversion  Date (as defined  below)  occurs on or
before the 119th day following the Closing Date,  (ii) the lessor of (A) 100% of
the Closing  Price or (B) the  current  market  price per share of Common  Stock
(determined as provided in Section 5) as of the applicable  Conversion  Date, if
the  applicable  Conversion  Date  occurs  on or after  the  120th day after the
Closing  Date and on or before the 179th day after the Closing Date or (iii) the
lesser of (A) 100% of the Closing Price and (ii) 85% of the current market price
per share of Common  Stock  (determined  as  provided  in  Section  5) as of the
applicable  Conversion  Date for any  Conversion  Date occurring on or after the
180th day after the  Closing  Date,  subject to  adjustment  and the  conditions
described herein.

<PAGE>
                  (b) (i) Any holder of shares of the Series A  Preferred  Stock
         electing to convert shares  thereof  pursuant to Section 4(a) shall (A)
         transmit by facsimile,  for receipt on the proposed date of conversion,
         a copy of a fully completed and executed notice of conversion  ("Notice
         of  Conversion") to the Corporation at the office of the Corporation or
         its  designated  transfer  agent (the  "Transfer  Agent"),  in the form
         attached as Exhibit A hereto, and (B) surrender to a common carrier for
         delivery to the office of the  Corporation or the Transfer  Agent,  the
         original  certificates  representing the Series A Preferred Stock being
         converted  (the  "Preferred  Stock  Certificates"),  duly  endorsed for
         cancellation. The Corporation shall, upon the timely written request of
         a holder of shares of the Series A Preferred Stock, promptly provide in
         writing to such holder,  via facsimile  transmission,  the  appropriate
         numbers for the Corporation and the Transfer Agent to be used to effect
         an election in accordance with this subparagraph (i).

                           (ii) Upon receipt by the  Corporation of transmission
         of a facsimile copy of such Notice of Conversion, the Corporation shall
         as soon as  practicable  (but in no event  later than 12:00 noon on the
         next  business  day after  receipt  thereof)  send,  via  facsimile,  a
         confirmation  of receipt of such Notice of  Conversion  to such holder,
         which shall specify that the Notice of Conversion has been received and
         the name and telephone  number of a contact  person at the  Corporation
         whom the holder should contact  regarding  information  related to such
         conversion.  Upon receipt by the  Corporation  or the Transfer Agent of
         the certificate(s)  representing the shares of Series A Preferred Stock
         to  be  converted   pursuant  to  such  Notice  of  Conversion  (or  an
         indemnification   undertaking   in  form   and   substance   reasonably
         satisfactory to the Corporation with respect to such shares in the case
         of their  loss,  theft or  destruction)  together  with the  originally
         executed  and  completed   Notice  of  Conversion  (such  date  of  the
         Corporation's receipt of all such documents being referred to herein as
         the "Final  Receipt  Date"),  the  Corporation  or  Transfer  Agent (as
         applicable) shall, as soon as possible on or after the applicable Final
         Receipt  Date,  but in any event within two (2) business days after the
         applicable  Final Receipt Date, issue and surrender to a common carrier
         for either  overnight  delivery  (if  delivery is to be made inside the
         United  States)  or two (2) day  delivery  (if  delivery  is to be made
         outside the United  States) to such holder at the address  specified in
         the Notice of  Conversion,  a  certificate  for the number of shares of
         Common  Stock to which such  holder  shall be entitled as in respect of
         the related conversion.  In the event of a partial conversion of shares
         of Series A Preferred Stock represented by certificate(s)  delivered to
         the  Corporation in respect of any  conversion,  the  Corporation  will
         return  to  the  applicable  holder  a  certificate  representing  such
         holder's  remaining shares of Series A Preferred Stock that were not so
         converted.  In the case of any dispute between the Corporation and such
         holder as to the calculation of the applicable Conversion

                                       -5-
<PAGE>
         Price  evidenced  by a  notice  to such  effect  (a  "Dispute  Notice")
         delivered to the  Corporation by such holder prior to the Final Receipt
         Date, the Corporation shall promptly issue to such holder the number of
         shares of Common  Stock  that is not  disputed  and  shall  submit  the
         disputed calculations to its outside accountant within two (2) business
         days after the Final Receipt  Date.  The  Corporation  shall cause such
         accountant to perform the  calculations  and notify the Corporation and
         the holder of the results no later than two (2) business days after the
         date that such outside  accountant is delivered a copy of such holder's
         Dispute Notice by the Corporation  pursuant to the preceding  sentence.
         Such accountant's calculation shall be deemed conclusive and binding on
         the Corporation and such holder absent manifest error.

                           (iii) The effective  date of a particular  conversion
         (the  "Conversion  Date") other than  pursuant to Section 4(c) shall be
         deemed to be the date on which the advance  copy of the related  Notice
         of Conversion  in respect of such  conversion is received by either the
         Corporation or the Transfer Agent by facsimile transmission as provided
         in  paragraph  (ii) above,  provided  that (A) such advance copy of the
         Notice of Conversion is transmitted by facsimile to and received by the
         Corporation before 11:59 p.m., New York City time, on such date and (B)
         the original certificates  representing the Series A Preferred Stock to
         be converted (or an  indemnification  undertaking in form and substance
         reasonably  satisfactory to the Corporation with respect to such shares
         in the case of their loss,  theft or  destruction),  together  with the
         originally executed and completed Notice of Conversion, are surrendered
         by depositing such  certificates and Notice of Conversion with a common
         carrier,  as provided  above,  and received by the  Corporation  or the
         Transfer Agent on or before the second (2nd) business day following the
         date that the related  advance copy of the related Notice of Conversion
         is received by the Corporation or the Transfer Agent. In the event that
         all such documents are not received  within two (2) business days after
         such date, such Notice of Conversion  shall be deemed null and void and
         no conversion of Series A Preferred Stock shall be effected thereby.

                           (iv) As of any Conversion Date, the person or persons
         entitled to receive the shares of the Common  Stock  issuable  upon the
         related  conversion of shares of Series A Preferred  Stock  pursuant to
         this Section 4 shall be treated for all  purposes as the record  holder
         or holders of the shares of Common  Stock  issuable  in respect of such
         conversion on said date.  From and after the Conversion Date in respect
         of such shares of Series A Preferred Stock, all such shares of Series A
         Preferred  Stock shall be deemed to have been  converted into shares of
         Common Stock at the applicable  conversion rate, all stock dividends on
         such shares of the Series A Preferred Stock shall cease to accrue,  and
         all rights of the  holders  thereof  as  holders of Series A  Preferred
         Stock, except the right to

                                       -6-
<PAGE>
         receive all accrued and unpaid stock  dividends to such Conversion Date
         at the applicable  rate for such shares of Series A Preferred Stock and
         the right to receive  certificates  representing shares of Common Stock
         issuable upon conversion of such shares (including, without limitation,
         with respect to such stock dividends),  shall cease and terminate, such
         shares of Series A Preferred  Stock shall not thereafter be transferred
         (except  with  the  consent  of the  Corporation)  on the  books of the
         Corporation  and such shares shall not be deemed to be outstanding  for
         any  purpose  whatsoever.  The  rights of a holder to elect to  convert
         shares of Series A  Preferred  Stock under this  Section  4(a) and 4(b)
         shall cease and terminate  immediately  after the Mandatory  Conversion
         Date.

                  (c) Subject to Section  4(d), to the extent that any shares of
Series A  Preferred  Stock  held by a  holder  thereof  have not been  converted
pursuant to Sections 4(a) and 4(b) as of the  Mandatory  Conversion  Date,  such
holder  shall be deemed to have  elected to  convert  such  remaining  shares of
Series A Preferred Stock as of the Mandatory Conversion Date (without any action
required by such holder) and the Corporation  shall issue shares of Common Stock
to such holder and satisfy its other  obligations  under Section 4(a) and (b) as
if such  holder  had  elected  to  convert  such  remaining  shares  of Series A
Preferred  Stock  pursuant  to  Sections  4(a)  and  4(b)  as of  the  Mandatory
Conversion Date.

                  (d)  Notwithstanding  anything herein to the contrary,  in the
event that (i) a holder of Series A Preferred Stock elects (or is deemed to have
elected) to convert shares of Series A Preferred Stock pursuant to Sections 4(a)
and 4(b) or pursuant to Section 4(c) for which a  Denominator  that is less than
the Closing Price is utilized in the  calculation  (pursuant to Section 4(a)) of
the number of shares of Common  Stock to be issued in such  conversion  and (ii)
such  conversion  would  result in such  holder  receiving,  as a result of such
conversion,  a number of shares of Common Stock that, together with other shares
of Common Stock  issued to such holder (or any  affiliate of such holder) in any
prior conversion(s) of Series A Preferred Stock that utilized a Denominator that
was less than the Closing Price in the calculation (pursuant to Section 4(a)) of
the  number of shares of  Common  Stock to be issued in such  conversion,  would
equal or exceed  twenty  percent  (20%) of the  shares  of  Common  Stock of the
Corporation  outstanding  on the  Closing  Date (the  "Threshold  Amount"),  the
Corporation  shall (i) issue to such holder the number of shares of Common Stock
otherwise  required to be issued to such  holder as a result of such  conversion
(including any shares of Common Stock  representing  cumulative  stock dividends
accrued to the applicable Conversion Date pursuant to Section 2) LESS the number
of shares of Common  Stock  otherwise  issuable to such holder  pursuant to such
conversion  in excess of the  Threshold  Amount (the  "Excess  Shares") and (ii)
shall  remit to such  holder,  in lieu of the Excess  Shares,  an amount of cash
equal to the number of Excess Shares  multiplied by the current market price per
share of Common Stock  (determined  as provided in Section 5)  determined  as of
such  Conversion  Date.  Upon such  issuance of Common Stock and payment of such
cash to the holder in lieu of the

                                       -7-

<PAGE>
Excess Shares, the Corporation's  obligations to such holder arising as a result
of such  conversion  (including the  Corporation's  obligation to pay cumulative
stock dividends  through the applicable  Conversion  Date) shall be deemed fully
satisfied.

                  (e) No fractional shares of Common Stock or scrip representing
fractional  shares  shall be issued  upon  conversion  of shares of the Series A
Preferred Stock pursuant to this Section 4. If more than one share of the Series
A Preferred  Stock shall be surrendered  for conversion by the same holder,  the
number of full shares of Common  Stock which shall be issuable  upon  conversion
thereof shall be computed on the basis of the aggregate  number of shares of the
Series A Preferred  Stock so  surrendered.  Instead of any fractional  shares of
Common Stock which would  otherwise be issuable upon conversion of any shares of
the Series A Preferred  Stock,  the  Corporation  shall pay a cash adjustment in
respect of such  fraction in an amount equal to the same fraction of the closing
bid price for Common Stock  determined as of the last business day preceding the
Conversion  Date in respect of such  shares.  The closing bid price for such day
shall be the last  reported  bid price on the  American  Stock  Exchange,  or if
Common  Stock is not listed or  admitted  to trading  on such  exchange,  on the
principal  national  securities  exchange  on which  Common  Stock is  listed or
admitted to trading  or, if not listed or  admitted  to trading on any  national
securities  exchange,  the  closing  bid price of Common  Stock on NASDAQ or any
comparable  system.  If Common  Stock is not quoted on NASDAQ or any  comparable
system,  the Board of Directors of the Corporation shall in good faith determine
the current market price on such basis as it considers appropriate.

                  (f) When shares of Series A Preferred  Stock are converted (or
deemed  converted) by a holder pursuant to this Section 4, the Corporation shall
pay any documentary,  stamp or similar issue or transfer tax due on the issue of
Common Stock upon such conversion.

                  (g) The  Corporation  shall  reserve  at all  times out of the
Corporation's authorized but unissued shares of Common Stock a sufficient number
of shares  of Common  Stock to permit  the  conversion  of the then  outstanding
shares of the  Series A  Preferred  Stock  pursuant  to this  Section 4 and such
reserved  shares shall not be used for any other  purpose.  All shares of Common
Stock  which may be issued upon  conversion  of shares of the Series A Preferred
Stock  pursuant  to this  Section  4 shall be  validly  issued,  fully  paid and
nonassessable.  In  order  that  shares  of  Common  Stock  may be  issued  upon
conversion  of shares of the Series A Preferred  Stock,  the  Corporation  shall
comply with all applicable  Federal and State  securities  laws and use its best
efforts to list such shares of Common Stock to be issued upon conversion on each
securities exchange on which Common Stock is listed.

                  (h) The conversion rate (and the components thereof) in effect
at any time for  conversion  of  Series A  Preferred  Stock  into  Common  Stock
pursuant to this Section 4 shall be subject to  adjustment  from time to time as
follows:

                                       -8-
<PAGE>
                  (i) In the event that the Corporation shall (1) pay a dividend
         in shares of  Common  Stock to  holders  of  Common  Stock,  (2) make a
         distribution in shares of Common Stock to holders of Common Stock,  (3)
         subdivide the outstanding  shares of Common Stock into a greater number
         of shares of Common Stock, (4) combine the outstanding shares of Common
         Stock into a smaller  number of shares of Common Stock or (5) otherwise
         increase or decrease the number of  outstanding  shares of Common Stock
         through  reclassification  or any other  event  similar  to the  events
         described in clauses (1) through (4) above,  the  conversion  rate (and
         the  components   thereof)  in  effect   pursuant  to  this  Section  4
         immediately  prior to such  action  shall  be  adjusted  to the  extent
         required  to give  effect to the  impact of any such  event so that the
         holder  of any  shares  of the  Series  A  Preferred  Stock  thereafter
         surrendered for conversion pursuant to this Section 4 shall be entitled
         to  receive  the number of shares of Common  Stock  which he would have
         owned immediately following such action had such shares of the Series A
         Preferred  Stock  been  converted   immediately  prior  thereto.   Such
         adjustment  shall be made  whenever  any event listed above shall occur
         and shall become effective (A) immediately after the record date in the
         case of a dividend  or a  distribution  or other  applicable  event for
         which a record  date is used and (B)  immediately  after the  effective
         date in the case of a subdivision or  combination  or other  applicable
         event for which a record date is not used.

                           (ii) In case the Corporation  shall distribute to all
         holders of the Common Stock shares of any class of capital  stock other
         than Common  Stock,  evidences of  indebtedness  or other assets (other
         than  non-extraordinary  cash  dividends  out of  current  or  retained
         earnings),  or shall distribute to substantially  all holders of Common
         Stock rights or warrants to subscribe for securities, then in each such
         case the number of shares of the Common  Stock into which each share of
         the Series A Preferred  Stock shall be converted shall be adjusted (and
         appropriate  adjustments  shall be made to the  component  parts of the
         applicable  conversion rate) so that such number shall equal the number
         determined  by  multiplying  the number of shares of Common  Stock into
         which  such  share of the  Series A  Preferred  Stock  was  convertible
         immediately  prior to the date of such  distribution  by a fraction  of
         which the numerator  shall be the current  market price of Common Stock
         (determined  as  provided  in Section 5) on the record  date  mentioned
         below, and of which the denominator  shall be such current market price
         of Common Stock, less the then fair market value (as determined in good
         faith by the Board of Directors of the Corporation, whose determination
         shall be conclusive  evidence of such fair market value) of the portion
         of the assets so distributed or of such subscription rights or warrants
         applicable to one share of Common Stock.  Such adjustment  shall become
         effective  immediately  after the record date for the  determination of
         the holders of Common Stock entitled to receive such distribution.

<PAGE>
                           (iii)  The  Corporation  shall  provide  at  least 10
         business days advance notice to holders of Series A Preferred  Stock of
         any record date or other  applicable date for determining  shareholders
         entitled to participate in any of the events  described in this Section
         4(h) or other  similar  events not described in this Section 4(h) which
         would have a dilutive  effect on the  Series A  Preferred  Stock or the
         Common Stock into which the Series A Preferred Stock is convertible.

                  (i) No  adjustment  in the  conversion  rate (or its component
parts)  under this  Section 4 shall be  required  until  cumulative  adjustments
result in a concomitant change of 1% or more of the conversion rate as in effect
prior to the last adjustment of the conversion rate; PROVIDED, HOWEVER, that any
adjustments  which by reason of this  Section  4(i) are not  required to be made
shall be carried  forward and taken into account in any  subsequent  adjustment.
All  calculations  under this  Section 4 shall be made to the nearest cent or to
the nearest  one-hundredth  of a share, as the case may be. No adjustment to the
conversion rate shall be made for non-extraordinary cash dividends.

                  (j) In the  event  that,  as a result  of an  adjustment  made
pursuant  to Section  4(h),  the  holder of any share of the Series A  Preferred
Stock thereafter surrendered for conversion shall become entitled to receive any
shares of capital  stock of the  Corporation  other than shares of Common Stock,
thereafter the number of such other shares so receivable  upon conversion of any
shares of the Series A Preferred  Stock shall be subject to adjustment from time
to time in a manner  and on terms as nearly  equivalent  as  practicable  to the
provisions with respect to the Common Stock contained in this Section 4.

                  (k) The  Corporation may make such increases in the conversion
rate,  in  addition  to those  required  by  Sections  4(h)(i)  and (ii),  as it
considers to be advisable in order that any event treated for Federal income tax
purposes  as a  dividend  of stock or stock  rights  shall not be taxable to the
recipients thereof.

                  (l) Whenever the conversion  rate (or any components  thereof)
is adjusted  pursuant to this Section 4, the Corporation  shall promptly mail to
all holders of record of shares of the Series A Preferred  Stock a notice of the
adjustment  and shall  cause to be  prepared a  certificate  signed by the chief
financial officer of the Corporation or, if requested in writing by holders of a
majority  of the  shares of  Series A  Preferred  Stock  then  outstanding,  the
Corporation's  outside  accountants  or  a  reputable  investment  banking  firm
selected by the Corporation  setting forth the adjusted conversion rate (and the
component  parts  thereof)  and a brief  statement of the facts  requiring  such
adjustment and the  computation  thereof.  Such  certificate  shall forthwith be
filed with each transfer agent for the shares of the Series A Preferred Stock.

                  (m)  If  any  of  the   following   shall   occur:   (i)   any
reclassification or change of outstanding shares of Common Stock

                                      -10-

<PAGE>
issuable upon conversion of shares of the Series A Preferred Stock (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),  (ii)  any
consolidation  or merger to which the Corporation is a party other than a merger
in which the Corporation is the continuing corporation and which does not result
in any  reclassification  of, or  change  (other  than a change in name,  or 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)  in,  outstanding  shares of Common
Stock  or  (iii)  any  sale or  conveyance  of all or  substantially  all of the
property or business of the Corporation as an entirety, then the Corporation, or
such  successor  or  purchasing  corporation,  as the case may be,  shall,  as a
condition precedent to such  reclassification,  change,  consolidation,  merger,
sale or conveyance, provide in its certificate of incorporation or other charter
document  that each share of the Series A Preferred  Stock shall be  convertible
under this  Section 4 into the kind and  amount of shares of  capital  stock and
other   securities  and  property   (including   cash)   receivable   upon  such
reclassification,  change, consolidation, merger, sale or conveyance by a holder
of the number of shares of Common  Stock  deliverable  upon  conversion  of such
share   of  the   Series   A   Preferred   Stock   immediately   prior  to  such
reclassification,  change,  consolidation,  merger,  sale  or  conveyance.  Such
certificate  of  incorporation  or other  charter  document  shall  provide  for
adjustments  and  protection  which  shall  be as  nearly  equivalent  as may be
practicable to the  adjustments  provided for in this Section 4. If, in the case
of any  such  consolidation,  merger,  sale or  conveyance,  the  stock or other
securities and property  (including  cash)  receivable  thereupon by a holder of
Common Stock includes  shares of capital stock or other  securities and property
of a corporation other than the successor  purchasing  corporation,  as the case
may be, in such consolidation,  merger, sale or conveyance, then the certificate
of  incorporation  or other  charter  document of such other  corporation  shall
contain such  additional  provisions  to protect the interests of the holders of
shares  of the  Series A  Preferred  Stock  as the  Board  of  Directors  of the
Corporation shall reasonably consider necessary by reason of the foregoing.  The
provision   of  this   Section  4(m)  shall   similarly   apply  to   successive
consolidations, mergers, sales or conveyances.

                  (n) No sooner than fifteen (15)  business  days nor later than
five (5) business days prior to the consummation of a transaction referred to in
clauses (ii) or (iii) of Section 4(m) (a "Major Transaction"),  but not prior to
the public announcement of such Major Transaction, the Corporation shall deliver
written  notice (a "Notice  of Major  Transaction")  to each  holder of Series A
Preferred Stock,  which Notice of Major Transaction shall be deemed to have been
delivered to the holder one (1) business day after the Corporation's  sending of
such notice (for overnight delivery) by a common carrier, if such delivery is to
be made in the United States,  or two (2) business days after the  Corporation's
sending of such notice (for two (2) day  delivery)  by common  carrier,  if such
notice is to be  delivered  outside  the  United  States.  Such  Notice of Major
Transaction shall indicate the amount

                                      -11-
<PAGE>
and type(s) of consideration (the "Major Transaction Consideration") the holders
of Series A Preferred Stock would receive for their shares of Series A Preferred
Stock in the related Major Transaction. Such holder may elect to redeem all or a
portion of such  holder's  shares of Series A  Preferred  Stock for an amount in
cash equal to $125 per share of Series A Preferred  Stock held by such holder to
be so  redeemed  in  lieu  of  the  Major  Transaction  Consideration  or  other
securities  and/or  property  that would  otherwise  be  payable to such  holder
pursuant to Section  4(m). A holder may  exercise  such  election by  delivering
written notice of such election to the Corporation,  together with  certificates
for the shares of Series A Preferred  Stock to be redeemed  in  connection  with
such  election,  within five (5) business  days of the  holder's  receipt of the
related Notice of Major Transaction,  which notice shall be deemed given one (1)
business   day  after  the  holder  sends  such  notice   (together   with  such
certificates) from the United States by common carrier for overnight delivery or
two (2)  business  days after the holder sends such notice  (together  with such
certificates)  from outside the United States by common  carrier for two (2) day
delivery.  In the event  that such Major  Transaction  is not  completed  within
fifteen (15) business  days after the  Corporation  is given a holder's  related
notice of election  pursuant to the prior sentence,  such election shall be null
and  void  and  the  Corporation   shall  promptly  return  the   certificate(s)
representing  the Series A  Preferred  Stock  delivered  by such  holder to such
holder; provided, that the Corporation will comply with the notice provisions of
this  Section  4(n)  with  respect  to any  later  consummation  of  such  Major
Transaction.  This  Section  4(n)  shall  not  apply  in  respect  of any  Major
Transaction that occurs after the second anniversary of the Closing Date.

                  (o) (i)  After  the  occurrence  of a Change  in  Control  (as
         defined below), other than in connection with a Major Transaction, each
         holder  of Series A  Preferred  Stock  shall  have the  right,  at such
         holder's option,  to require the Corporation to redeem all or a portion
         of such  holder's  Series A Preferred  Stock for an amount per share in
         cash  equal  to the  greater  of (A) $125  and (B) the  product  of the
         aggregate number of shares of Common Stock into which a share of Series
         A Preferred  Stock is  convertible  (assuming such  conversion  were to
         occur on the last day preceding  the  effective  date for the Change of
         Control)  multiplied  by the current  market  price per share of Common
         Stock  (determined  as  provided  in  Section  5) as of the  last  date
         preceding the effective date of such Change of Control. As used in this
         Section 4(o), a "Change in Control" shall be deemed to have occurred at
         such time as either Douglas R. Eger or Thomas M. Fitzgerald cease to be
         either a director or officer of the Corporation.  The rights of holders
         of Series A Preferred  Stock under this Section 4(o) shall not apply in
         respect  of  any  Change  of  Control   that  occurs  after  the  first
         anniversary of the Closing Date.

                           (ii) The  Corporation  shall  provide  each holder of
         Series A Preferred  Stock with written  notice of the occurrence of any
         Change of Control (a "Change of Control Notice") within

                                      -12-
<PAGE>
         two (2) business  days after the  occurrence of such Change of Control.
         Each holder may require the  Corporation  to redeem all or a portion of
         such  holder's  shares of Series A  Preferred  Stock  pursuant  to this
         Section 4(o) by delivering  written  notice (a "Notice of Redemption at
         Option of Holder") to the  Corporation  to such effect  within ten (10)
         business days after receipt of the applicable Change of Control Notice,
         which Notice of  Redemption at Option of Holder shall be deemed to have
         been  delivered  one (1) business day after such holder's  sending,  if
         such notice is sent within the United States for overnight  delivery by
         a common carrier, or two (2) business days after such holder's sending,
         if such notice is sent from  outside  the United  States by two (2) day
         delivery by a common carrier.  Each such Notice of Redemption at Option
         of Holder  shall  indicate  the number of shares of Series A  Preferred
         Stock that have been selected by such holder for redemption.


                           (iii)   Each   holder    submitting    certificate(s)
         representing  shares of Series A Preferred  Stock for redemption  under
         this   Paragraph  4(o)  shall  send  such  holder's   Preferred   Stock
         Certificates  to be redeemed to the  Corporation  or its Transfer Agent
         and the Corporation  shall pay the applicable  redemption price to that
         holder within thirty (30) business days after the Corporation's receipt
         of such holder's  Notice of  Redemption  at Option of Holder;  provided
         that  such  holder's  certificate(s)  representing  shares  of Series A
         Preferred Stock to be redeemed (or an indemnification  undertaking with
         respect to such shares in the case of their loss, theft or destruction)
         shall have been so delivered to the Corporation or its Transfer Agent.

                  (p) As used herein,  "business day" means a day of the year on
which banks are not required or authorized to close in New York City, New York.

                  (q) It is  understood  that the  restrictions  on any holder's
ability to convert such holder's  shares of Series A Preferred  Stock  contained
herein may be supplemented by separate written agreement between such holder and
the Corporation.

                  Section  5.  CALCULATIONS  OF CURRENT  MARKET  PRICE OF COMMON
STOCK.  For purposes of  calculations  relating to the Series A Preferred  Stock
that refer to the current  market price per share of Common  Stock,  the current
market price per share of Common Stock on or as of any day shall be deemed to be
the average of the closing bid prices for the ten (10) consecutive  trading days
ending the last  trading day before the day in  question.  The closing bid price
for  each day  shall  be the last  reported  bid  price  on the  American  Stock
Exchange,  or if Common  Stock is not  listed or  admitted  to  trading  on such
exchange, on the principal national securities exchange on which Common Stock is
listed or  admitted  to trading  or, if not listed or admitted to trading on any
national securities exchange, the closing bid price of Common Stock on NASDAQ or
any comparable system, or if Common Stock is not quoted

                                      -13-
<PAGE>
on NASDAQ or any  comparable  system,  the closing bid price as furnished by any
two members of the National  Association of Securities  Dealers,  Inc.  selected
from time to time by the Corporation for that purpose. If Common Stock is not so
quoted  on NASDAQ  or any  comparable  system,  the  Board of  Directors  of the
Corporation  shall  reasonably  and in good faith  determine the current  market
price on such basis as it considers appropriate.  For example, in the event that
the current  market price per share of Common Stock is to be  determined as of a
Conversion  Date, the current market price per share of Common Stock shall equal
the average of the last  reported  bid price as reported by the  American  Stock
Exchange for the ten (10)  consecutive  trading days ending the last trading day
before  such  Conversion  Date  (assuming  that the  Common  Stock is listed and
admitted for trading on the American Stock Exchange and a reported bid price for
Common Stock is placed on the American Stock Exchange on each such trading day).

                  Section 6.  LIMITATIONS.  (a) In addition to any other  rights
provided  by  applicable  law,  so long as any shares of the Series A  Preferred
Stock are outstanding,  the Corporation shall not, without the affirmative vote,
or the written consent as provided by law, of the holders of at least two-thirds
(2/3) of the  outstanding  shares of the Series A Preferred  Stock,  voting as a
separate class,

                           (i) create, authorize or issue any class or series of
                  capital  stock,  or rights to subscribe to or acquire,  or any
                  security  convertible  into,  any class or  series of  capital
                  stock  ranking  as to payment of  dividends,  distribution  of
                  assets upon liquidation or voting rights,  prior to the Series
                  A Preferred Stock; or

                           (ii)  amend,  alter or  appeal,  whether  by  merger,
                  consolidation  or  otherwise,  any  of the  provisions  of the
                  Certificate of  Incorporation  (including this  Certificate of
                  Designation)  that  would  change the  preferences,  rights or
                  powers with  respect to the Series A Preferred  Stock so as to
                  affect the Series A Preferred Stock adversely.

                  (b) In addition  to any other  rights  provided by  applicable
law, so long as any shares of the Series A Preferred Stock are outstanding,  the
Corporation  shall not, without the affirmative  vote, or the written consent as
provided by law, of the holders of at least  two-thirds (2/3) of the outstanding
shares of the Series A Preferred  Stock,  voting as a separate  class,  issue or
agree  to issue  any  Common  Stock or any  security  convertible  or  otherwise
exchangeable,  directly or indirectly, for Common Stock if such shares of Common
Stock are to be issued, or such convertible securities are to be converted to or
exchanged for shares of Common Stock, at a price per share less than the current
market  price for the Common Stock  (determined  as provided in Section 5) as of
the day  immediately  preceding the date of the issuance of such Common Stock or
such  convertible  or  exchangeable  security  (as the case  may be);  provided,
however,  that the restrictions  contained in this paragraph (b) shall not apply
(i) to the issuance of any such

                                      -14-
<PAGE>
convertible or exchangeable securities that are convertible or exchangeable at a
fixed price (and not a floating  price) per share  equal to or greater  than the
current market price for the Common Stock  (determined as provided in Section 5)
as of the date of issuance of such convertible or exchangeable security, (ii) to
the issuance of Common Stock and other  securities of the  Corporation  issuable
upon the exercise or conversion of options, warrants on other rights to purchase
securities of the  Corporation  outstanding as of the date hereof,  (iii) to the
issuance  of  any  securities  to  officers,   directors  or  employees  of  the
Corporation or any of its  subsidiaries,  (iv) to the issuance of any securities
of the  Corporation  in an  underwritten  public  offering  or (v) to any  other
issuance of securities  after the date that is 90 days after the Closing Date if
the holders of Series A Preferred  Stock are first delivered a written notice (a
"Right of First Refusal Notice") from the Corporation offering such holders on a
PRO RATA basis the right to purchase all or a portion of the related  securities
at the same  price  (and on the same  terms  and  conditions,  offered  to other
proposed  investors  (which  notice  shall  set  forth  such  price,  terms  and
conditions). In the event that the Corporation delivers a Right of First Refusal
Notice to any holder of Series A Preferred  Stock, the failure by such holder to
commit in writing to purchase such  holder's pro rata portion of the  securities
identified in such Right of First  Refusal  Notice within five (5) business days
of delivery thereof may be deemed by the Corporation to constitute such holder's
determination  not to so purchase such securities and the Corporation shall then
be permitted to sell such  securities to other investors at the price and on the
terms and conditions set forth in such notice. The rights of holders of Series A
Preferred   Stock  under  this  paragraph  (b)  shall  terminate  on  the  first
anniversary of the Closing Date.

                  (c)  Notwithstanding   the  foregoing,   except  as  otherwise
required by applicable  law,  nothing herein  contained  shall require a vote or
consent  of the  holders  of Series A  Preferred  Stock in  connection  with any
increase in the total number of authorized  shares of Common Stock.  The holders
of Series A Preferred  Stock shall not be entitled to vote on any matter  except
(i) as provided in this Section 6 and (ii) as required by law.

                  Section 7. LOST OR STOLEN  CERTIFICATES.  Upon (i)  receipt by
the Corporation from a holder of evidence satisfactory to the Corporation of the
loss, theft,  destruction of any certificate(s)  representing shares of Series A
Preferred  Stock  and of an  indemnification  undertaking  by the  holder to the
Corporation  that is reasonably  satisfactory  to the  Corporation  or (ii) upon
surrender and  cancellation of  certificate(s)  representing  shares of Series A
Preferred  Stock that have been  mutilated,  the  Corporation  shall execute and
deliver  to such  holder  new  certificate(s)  representing  shares  of Series A
Preferred Stock of like tenor and date.  However,  the Corporation  shall not be
obligated to re-issue such lost, stolen,  destroyed or mutilated  certificate(s)
representing shares of Series A Preferred Stock if such holder contemporaneously
requests the Corporation to convert such shares

                                      -15-

of Series A Preferred Stock into shares of Common Stock or otherwise redeem such
shares pursuant to the terms hereof.

                  IN  WITNESS   WHEREOF,   the   Corporation   has  caused  this
Certificate  of  Designation  to be signed by Douglas R. Eger,  its Chairman and
Chief Executive Officer,  and attested by George Lombardi,  its Secretary,  this
28th day of February, 1997.

                  The  undersigned  holder  of  shares  of  Series A  Cumulative

said Article the following new Article FOURTH:

                  "FOURTH:  The  total  number  of  shares  of  stock  that  the
                  Corporation  shall  have the  authority  to issue is (i) fifty
                  million  (50,000,000)  shares of Common Stock,  $.01 par value
                  ("Common Stock"), and (ii) three million (3,000,000) shares of
                  Preferred Stock, $.01 par value ("Preferred Stock").

(a)      COMMON STOCK.

         (i) GENERAL. The voting, dividend and liquidation rights of the holders
of Common Stock are subject to and qualified by the rights of the holders of the
Preferred  Stock of any series as may be  designated  by the Board of  Directors
upon any issuance of the Preferred Stock of any series.

                                   ARTICLE ONE

                                  STOCKHOLDERS

                  SECTION   1.1.   ANNUAL   MEETINGS.   An  annual   meeting  of
stockholders to elect directors and transact such other business as may properly
be  presented  to the  meeting  shall  be held at such  place  as the  Board  of
Directors may from time to time fix, if that day shall be a legal holiday in the
jurisdiction  in which  the  meeting  is to be held,  then on the next day not a
legal holiday or as soon thereafter as may be practical, determined by the Board
of Directors.

                  SECTION  1.2.   SPECIAL   MEETINGS.   A  special   meeting  of
stockholders  may be  called  at any  time  by the  Board  of  Directors  or the
President and shall be called by any of them or by the Secretary upon receipt of
a written  request to do so specifying  the matter or matters,  appropriate  for
action at such a meeting,  proposed to be presented at the meeting and signed by
holders of record of a majority of the shares of stock that would be entitled to
be voted on such  matter or  matters  if the  meeting  were held on the day such
request is  received  and the  record  date for such  meeting  were the close of
business on the  preceding  day. Any such meeting shall be held at such time and
at such place,  within or without the State of Delaware,  as shall be determined
by the body or person  calling such meeting and as shall be stated in the notice
of such meeting.

                  SECTION   1.3.   NOTICE  OF  MEETING.   For  each  meeting  of
stockholders written notice shall be given stating the place, date and hour and,

any meeting shall be given not less than 10 or more than 60 days before the date
of the meeting to each stockholder  entitled to vote at such meeting. If mailed,
notice  shall be deemed to be given when  deposited  in the United  States mail,

the shares of stock  entitled to be voted  present in person or  represented  by
proxy at a meeting shall  constitute a quorum for the transaction of business at
the
<PAGE>
meeting,  but in the  absence  of a quorum  the  holders  of record  present  or
represented  by proxy at such  meeting may vote to adjourn the meeting from time
to time,  without notice other than announcement at the meeting,  until a quorum
is obtained.  At any such adjourned  session of the meeting at which there shall
be present or  represented  the  holders  of record of the  requisite  number of
shares,  any business may be transacted  that might have been  transacted at the
meeting as originally called.

                  SECTION  1.5.  CHAIRMAN  AND  SECRETARY  AT  MEETING.  At each
meeting of stockholders the President,  or in his absence the person  designated
in writing by the  President,  or if no person is so  designated,  then a person
designated by the Board of Directors,  shall preside as chairman of the meeting;
if no person is so  designated,  then the  meeting  shall  choose a chairman  by
plurality  vote.  The  Secretary,  or in his absence a person  designated by the
chairman of the meeting, shall act as secretary of the meeting.

                  SECTION 1.6. VOTING;  PROXIES. Except as otherwise provided by
Delaware law or the Certificate of Incorporation,  and subject to the provisions
of Section 1.10:

stockholders  be  entitled  to one vote for each share of capital  stock held by
him.

                           (b) Each stockholder entitled to vote at a meeting of
stockholders  or to express  consent or dissent to  corporate  action in writing
without a meeting  may  authorize  another  person or  persons to act for him by
proxy, but no such proxy shall be voted or acted upon after three years from its
date, unless the proxy provides for a longer period.

                           (c) Directors shall be elected by a plurality vote.

                           (d) Each matter,  other than  election of  directors,
properly  presented  to any meeting  shall be decided by a majority of the votes
cast on the matter.

                           (e) Election of  directors  and the vote on any other
matter  presented to a meeting shall be by written  ballot only if so ordered by
the  chairman of the meeting or if so requested  by any  stockholder  present or
represented by proxy at the meeting entitled to vote in such election or on such
matter, as the case may be.

                  SECTION 1.7. ADJOURNED MEETINGS. A meeting of stockholders may
be  adjourned  to another  time or place as  provided  in Section 1.4 or 1.6(d).
Unless the Board of Directors  fixes a new record date,  stockholders  of record
for an adjourned

                                       -2-
<PAGE>
meeting  shall be as  originally  determined  for the  meeting  from  which  the
adjournment  was taken. If the adjournment is for more than 30 days, or if after
the adjournment a new record date is fixed for the adjourned  meeting,  a notice
of the adjourned  meeting shall be given to each  stockholder of record entitled
to vote. At the adjourned meeting any business may be transacted that might have
been transacted at the meeting as originally called.

                  SECTION 1.8.  CONSENT OF STOCKHOLDERS IN LIEU OF MEETING.  Any
action that may be taken at any annual or special meeting of stockholders may be
taken  without a meeting,  without prior notice and without a vote, if a consent
in writing, setting forth the action so taken, shall be signed by the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary  to  authorize  or take such  action at a meeting  at which all shares
entitled to vote thereon  were  present and voted.  Notice of the taking of such
action shall be given promptly to each stockholder that would have been entitled
to vote thereon at a meeting of stockholders and that did not consent thereto in
writing.

                  SECTION 1.9. LIST OF  STOCKHOLDERS  ENTITLED TO VOTE. At least
10 days before every meeting of stockholders a complete list of the stockholders
entitled to vote at the meeting,  arranged in alphabetical order and showing the
address of each  stockholder and the number of shares  registered in the name of
each stockholder,  shall be prepared and shall be open to the examination of any
stockholder  for any purpose germane to the meeting,  during  ordinary  business
hours, for a period of at least 10 days prior to the meeting,  at a place within
the city where the meeting is to be held.  Such list shall be produced  and kept
at the time and place of the  meeting  during the whole time  thereof and may be
inspected by any stockholder who is present.

                  SECTION  1.10.  FIXING  OF  RECORD  DATE.  In  order  that the
Corporation may determine the  stockholders  entitled to notice of or to vote at
any meeting of stockholders or any adjournment thereof, or to express consent to
corporate action in writing without a meeting, or entitled to receive payment of
any dividend or other  distribution  or allotment of any rights,  or entitled to
exercise any rights in respect of any change, conversion or exchange of stock or
for the purpose of any other lawful  action,  the Board of Directors may fix, in
advance,  a record  date,  which  shall not be more than 60 or less than 10 days
before  the date of such  meeting,  nor  more  than 60 days  prior to any  other
action. If no record date is fixed, the record date for determining stockholders
entitled  to notice of or to vote at a meeting of  stockholders  shall be at the
close of business on the day next  preceding  the day on which  notice is given,
or, if notice is waived,  at the close of business on the day next preceding the
day on which the meeting is held; the record date for determining

                                       -3-
<PAGE>
stockholders  entitled to express consent to corporate action in writing without
a meeting, when no prior action by the Board of Directors is necessary, shall be

any  other  purpose  shall be at the close of  business  on the day on which the
Board of Directors adopts the resolution relating thereto.

VACANCIES.  The number of  directors  that shall  constitute  the whole Board of
Directors  shall be four,  which  number  may be  changed  from  time to time as
determined by action of the Board of Directors taken by the affirmative  vote of
a majority of the whole Board of  Directors.  Directors  shall be elected at the
annual meeting of stockholders to hold office,  subject to Sections 2.2 and 2.3,
until  the next  annual  meeting  of  stockholders  and until  their  respective
successors are elected and qualified.  Vacancies and newly created directorships
resulting from any increase in the authorized  number of directors may be filled
by a majority of the directors then in office,  although less than a quorum,  or
by the sole remaining  director,  and the directors so chosen shall hold office,
subject to Sections 2.2 and 2.3, until the next annual  meeting of  stockholders
and until their respective successors are elected and qualified.

                  SECTION 2.2. RESIGNATION.  Any director of the Corporation may

Directors,  the  President  or  the  Secretary  of  the  Corporation.  Any  such
resignation  shall take effect at the time  specified  therein or, if no time be
specified,  upon  receipt  thereof  by  the  Board  of  Directors  or one of the
above-named  officers;  and, unless  specified  therein,  the acceptance of such
resignation  shall  not be  necessary  to make it  effective.  When  one or more
directors shall resign from the Board of Directors effective at a future date, a
majority of the directors then in office,  including those who have so resigned,
shall have power to fill such  vacancy or  vacancies,  the vote  thereon to take
effect when such resignation or resignations  shall become  effective,  and each
director so chosen shall hold office as provided in these By-Laws in the filling
of other vacancies.

                  SECTION  2.3.  REMOVAL.  Any  one  or  more  directors  may be

notice in the United States mail,  first class,  postage  prepaid,  at least two
days  before the day fixed for the  meeting  addressed  to each  director at his

                  SECTION  2.6.  CHAIRMAN  OF THE BOARD;  PRESIDING  OFFICER AND
SECRETARY  AT MEETINGS.  The Board of Directors  may elect one of its members to

Directors  shall be presided over by the Chairman of the Board or in his absence
by the President,  if a director, or if neither is present by such member of the

person presiding over the meeting.

                  SECTION  2.7.  QUORUM.  A  majority  of  the  whole  Board  of

meeting, until such time as a quorum is present. Except as otherwise required by
the Certificate of Incorporation or the By-Laws, the vote of the majority of the
directors present at a

                                       -5-

                  SECTION  2.8.  MEETING BY  TELEPHONE.  Members of the Board of
Directors or of any committee  thereof may  participate in meetings of the Board
of Directors or of such  committee by means of  conference  telephone or similar

person at such meeting.

                  SECTION  2.9.  ACTION  WITHOUT   MEETING.   Unless   otherwise
restricted by the Certificate of Incorporation, any action required or permitted
to be taken at any meeting of the Board of Directors or of any committee thereof

such  committee,  as the case may be, consent thereto in writing and the writing
or writings are filed with the minutes of  proceedings of the Board of Directors
or of such committee.

                  SECTION  2.10.  EXECUTIVE AND OTHER  COMMITTEES.  The Board of
Directors  may,  by  resolution  passed  by a  majority  of the  whole  Board of
Directors,  designate an Executive  Committee and one or more other  committees,

Directors may from time to time  determine.  Any such  committee,  to the extent
provided in such resolution or resolutions,  shall have and may exercise all the
powers and authority of the Board of Directors in the management of the business
and affairs of the Corporation, including the power to authorize the seal of the
Corporation  to be  affixed  to all  papers  that  may  require  it but no  such
committee  shall have such power of  authority  in  reference  to  amending  the
Certificate of Incorporation,  adopting an agreement of merger or consolidation,
recommending  to  the  stockholders  the  sale,  lease  or  exchange  of  all or

stockholders a dissolution of the  Corporation or a revocation of a dissolution,
or amending the By-Laws;  and unless the resolution  shall expressly so provide,
no such committee  shall have the power or authority to declare a dividend or to
authorize the issuance of stock. In the absence or  disqualification of a member
of a  committee,  the member or members  thereof  present at any meeting and not
disqualified  from voting,  whether or not he or they  constitute a quorum,  may
unanimously  appoint  another  member  of the Board of  Directors  to act at the
meeting  in the  place of any such  absent  or  disqualified  member.  Each such
committee  other  than the  Executive  Committee  shall have such name as may be
determined from time to time by the Board of Directors.

stated  salary for his services as a director or as a member of a committee  but

                  SECTION 4.1. STOCK  CERTIFICATES.  The interest of each holder
of stock of the Corporation  shall be evidenced by a certificate or certificates

<PAGE>
President or a Vice President and by the Treasurer or an Assistant  Treasurer or
the Secretary or an Assistant Secretary.  Any of or all the signatures appearing
on such certificate or certificates may be a facsimile. If any officer, transfer
agent or registrar who has signed or whose  facsimile  signature has been placed
upon a  certificate  shall have  ceased to be such  officer,  transfer  agent or
registrar before such certificate is issued, it may be issued by the Corporation
with the same effect as if he were such officer,  transfer agent or registrar at
the date of issue.

                  SECTION  4.2.  TRANSFER  OF STOCK.  Shares  of stock  shall be
transferable on the books of the Corporation pursuant to applicable law and such
rules  and  regulations  as the  Board  of  Directors  shall  from  time to time
prescribe.

                  SECTION 4.3.  HOLDERS OF RECORD.  Prior to due presentment for
registration  of transfer  the  Corporation  may treat the holder of record of a
share of its stock as the complete owner thereof  exclusively  entitled to vote,
to receive  notifications and otherwise entitled to all the rights and powers of
a complete owner thereof, notwithstanding notice to the contrary.

                  SECTION   4.4.   LOST,   STOLEN,    DESTROYED   OR   MUTILATED
CERTIFICATES.  The Corporation shall issue a new certificate of stock to replace
a certificate  theretofore issued by it alleged to have been lost,  destroyed or
wrongfully  taken,  if  the  owner  or his  legal  representative  (i)  requests
replacement,  before the Corporation  has notice that the stock  certificate has
been acquired by a bona fide  purchaser;  (ii) files with the Corporation a bond
sufficient  to  indemnify  the  Corporation  against  any claim that may be made
against it on  account  of the  alleged  loss or  destruction  of any such stock
certificate  or the  issuance  of any  such new  stock  certificate;  and  (iii)
satisfies  such other terms and  conditions  as the Board of Directors  may from
time to time prescribe.


                                  ARTICLE FIVE

                                  MISCELLANEOUS

                  SECTION 5.1.  INDEMNITY.  (a) The Corporation shall indemnify,
subject to the  requirements  of subsection (d) of this Section,  any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding, whether civil, criminal, administrative
or investigative  (other than an action by or in the right of the  Corporation),
by reason of the fact that he is or was a director,  officer,  employee or agent
of the Corporation,  or is or was serving at the request of the Corporation as a
director, officer,

                                       -9-

<PAGE>
employee or agent of another corporation,  partnership,  joint venture, trust or
other enterprise, against expenses (including attorneys' fees), judgments, fines
and  amounts  paid in  settlement  actually  and  reasonably  incurred by him in
connection with such action, suit or proceeding if he acted in good faith and in
a manner he reasonably believed to be in or not opposed to the best interests of
the Corporation  and, with respect to any criminal action or proceeding,  had no
reasonable  cause to believe his conduct was unlawful.  The  termination  of any
action, suit or proceeding by judgment, order, settlement,  conviction or upon a
plea of nolo  contendere  or its  equivalent,  shall not,  of  itself,  create a
presumption  that the person did not act in good faith and in a manner  which he
reasonably  believed  to be in or not  opposed  to  the  best  interests  of the
Corporation  and,  with  respect  to any  criminal  action  or  proceeding,  had
reasonable cause to believe that his conduct was unlawful.

                           (b) The Corporation  shall indemnify,  subject to the
requirements of subsection (d) of this Section, any person who was or is a party
or is  threatened  to be made a party to any  threatened,  pending or  completed
action or suit by or in the right of the  Corporation  to procure a judgment  in
its favor by reason of the fact that he is or was a director,  officer, employee
or  agent  of  the  Corporation  or is or was  serving  at  the  request  of the
Corporation as a director,  officer,  employee or agent of another  corporation,
partnership,   joint  venture,  trust  or  other  enterprise,  against  expenses
(including   attorneys'  fees)  actually  and  reasonably  incurred  by  him  in
connection  with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the  Corporation and except that no  indemnification  shall be
made in respect of any claim, issue or matter as to which such person shall have
been adjudged to be liable to the Corporation unless and only to the extent that
the Court of Chancery of the State of Delaware or the court in which such action
or  suit  was  brought  shall  determine  upon  application  that,  despite  the
adjudication of liability but in view of all the circumstances of the case, such
person is fairly and  reasonably  entitled to indemnity for such expenses  which
the Court of  Chancery  of the State of  Delaware or such other court shall deem
proper.

                           (c) To the extent that a director,  officer, employee
or agent of the Corporation,  or a person serving in any other enterprise at the
request of the  Corporation,  has been  successful on the merits or otherwise in
defense of any action,  suit or proceeding referred to in subsection (a) and (b)
of this  Section,  or in  defense  of any claim,  issue or matter  therein,  the
Corporation  shall indemnify him against  expenses  (including  attorneys' fees)
actually and reasonably incurred by him in connection therewith.

<PAGE>
                           (d) Any indemnification under subsections (a) and (b)
of this Section  (unless  ordered by a court)  shall be made by the  Corporation
only  as   authorized   in  the  specific   case  upon  a   determination   that
indemnification  of the  director,  officer,  employee or agent is proper in the
circumstances because he has met the applicable standard of conduct set forth in
subsections (a) and (b) of this Section. Such determination shall be made (1) by
the Board of Directors by a majority  vote of a quorum  consisting  of directors
who were not parties to such action, suit or proceeding, or (2) if such a quorum
is not obtainable,  or, even if obtainable a quorum of disinterested  directors,
or  (3)  by  independent  legal  counsel  in a  written  opinion,  or (4) by the
stockholders.

                           (e)  Expenses   incurred  by  a  director,   officer,
employee or agent in defending a civil or criminal  action,  suit or  proceeding
may be paid by the  Corporation  in  advance  of the final  disposition  of such
action,  suit or proceeding as authorized by the Board of Directors upon receipt
of an undertaking by or on behalf of the director, officer, employee or agent to
repay such amount if it shall  ultimately be determined  that he is not entitled
to be indemnified by the Corporation as authorized in this Section.

                           (f) The  indemnification  and advancement of expenses
provided by or granted pursuant to, the other  subsections of this Section shall
not  limit  the  Corporation  from  providing  any  other   indemnification   or
advancement of expenses permitted by law nor shall it be deemed exclusive of any
other rights to which those seeking  indemnification  may be entitled  under any
by-law, agreement, vote of stockholders or disinterested directors or otherwise,
both as to action in his official  capacity and as to action in another capacity
while holding such office.

                           (g)  The   Corporation   may  purchase  and  maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent  of  the  Corporation,  or who is or was  serving  at the  request  of the
Corporation as a director,  officer,  employee or agent of another  corporation,
partnership,  joint  venture,  trust or other  enterprise  against any liability
asserted against him and incurred by him in any such capacity, or arising out of
his  status as such,  whether  or not the  Corporation  would  have the power to
indemnify him against such liability under the provisions of this Section.

                           (h) The  indemnification  and advancement of expenses
provided  by, or  granted  pursuant  to this  section  shall,  unless  otherwise
provided when authorized or ratified,  continue as to a person who has ceased to
be a director,  officer, employee or agent and shall inure to the benefit of the
heirs, executors and administrators of such a person.

                           (i)      For the purposes of this Section, references
to "the Corporation"  shall include,  in addition to the resulting  corporation,
any  constituent  corporation  (including  any  constituent  of  a  constituent)
absorbed in a  consolidation  or merger  which,  if its separate  existence  had
continued,  would  have had power and  authority  to  indemnify  its  directors,
officers,  employees  or agents,  so that any  person who is or was a  director,
officer, employee or agent of such constituent corporation, or is or was serving
at the request of such constituent corporation as a director,  officer, employee
or agent of another  corporation,  partnership,  joint  venture,  trust or other
enterprise,  shall  stand in the same  position  under  the  provisions  of this
Section with respect to the resulting or surviving  corporation as he would have
with  respect to such  constituent  corporation  if its separate  existence  had
continued.

                           (j)      This Section 5.1 shall be construed to give
the  Corporation  the  broadest  power   permissible  by  the  Delaware  General
Corporation Law, as it now stands and as heretofore amended.

                  SECTION 5.2. WAIVER OF NOTICE.  Whenever notice is required by
the  Certificate of  Incorporation,  the By-Laws or any provision of the General
Corporation Law of the State of Delaware,  a written waiver  thereof,  signed by
the person  entitled to notice,  whether  before or after the time  required for
such notice,  shall be deemed equivalent to notice.  Attendance of a person at a
meeting  shall  constitute a waiver of notice of such  meeting,  except when the
person attends a meeting for the express purpose of objecting,  at the beginning
of the meeting,  to the  transaction of any business  because the meeting is not
lawfully  called or convened.  Neither the business to be transacted at, nor the
purpose of, any regular or special  meeting of the  stockholders,  directors  or
members of a committee of directors  need be specified in any written  waiver of
notice.

                  SECTION 5.3.  FISCAL YEAR. The fiscal year of the  Corporation
shall  start on such  date as the  Board of  Directors  shall  from time to time
prescribe.

                  SECTION 5.4.  CORPORATE  SEAL.  The corporate seal shall be in
such form as the Board of  Directors  may from time to time  prescribe,  and the
same may be used by causing it or a facsimile thereof to be impressed or affixed
or in any other manner reproduced.

                              AMENDMENT OF BY-LAWS
