                         ENZON, INC. AND SUBSIDIARIES
             Notes To Consolidated Condensed Financial Statements
                                  (Unaudited)


(1)  ORGANIZATION AND BASIS OF PRESENTATION

      The  unaudited  consolidated  condensed financial  statements  have  been
prepared  from  the  books  and records of  Enzon,  Inc.  and  subsidiaries  in
accordance with generally accepted  accounting principles for interim financial
information.  Accordingly, they do not  include  all  of  the  information  and
footnotes  required  by  generally  accepted accounting principles for complete
financial  statements.   In  the  opinion   of   management,   all  adjustments
(consisting only of normal and recurring adjustments) considered  necessary for
a  fair  presentation  have been included.  Interim results are not necessarily
indicative of the results that may be expected for the year.

(2)  NET LOSS PER COMMON SHARE

      Net loss per common  share  is based on net loss for the relevant period,
adjusted for cumulative undeclared  preferred  stock  dividends of $109,000 for
the  six  months ended December 31, 1995 and 1994, and $55,000  for  the  three
months ended December 31, 1995 and 1994, divided by the weighted average number
of shares issued  and  outstanding  during the period.  Stock options, warrants
and  common stock issuable upon conversion  of  the  preferred  stock  are  not
reflected  as  their  effect  would  be antidilutive for both primary and fully
diluted earnings per share computations.   The total number of shares issued to
former shareholders of Enzon Labs Inc. (formerly  known  as Genex Corporation),
which  was  acquired on October 31, 1991, have been included  in  the  weighted
average number  of  outstanding  shares,  as  if  all shares had been issued on

(4)  CASH FLOW INFORMATION

      The  Company  considers  all  highly  liquid  securities   with  original
maturities  of three months or less to be cash equivalents.  Cash payments  for
interest were  approximately  $11,000  and  $1,000  for  the  six  months ended
December  31,  1995 and 1994, respectively.  There were no income tax  payments
made for the six  months  ended  December  31,  1995  and 1994.  As part of the
commission due to the real estate broker in connection  with the termination of
the lease at 40 Kingsbridge Road, the Company issued 150,000 five-year warrants
to purchase the Company's Common Stock at $2.50 per share during the six months
ended December 31, 1995.  This transaction is a non-cash financing activity.

        Notes To Consolidated Condensed Financial Statements, Continued
                                  (Unaudited)


(5)  NON-QUALIFIED STOCK OPTION PLAN

      During the six months ended December 31, 1995, the Company issued 550,000
stock options at an average exercise price of $3.42 under  the  Company's  Non-
Qualified  Stock  Option  Plan  (the  "Plan"), of which 180,000 were granted to
executive officers of the Company.  None  of  the  options  granted  during the
period are exercisable as of December 31, 1995.  All options were granted  with
exercise  prices  that  equalled  or  exceeded  the  fair  market  value of the
underlying stock on the date of grant.

      On December 5, 1995, the stockholders voted to amend the Plan to increase
the number of shares reserved for issuance to 6,200,000.

(6)  RESTRUCTURING EXPENSE

      During  the  quarter  ended  March  31,  1995,  the  Company  recorded  a
restructuring  charge  related to a workforce reduction and the termination  of
one of its facility leases.  As of June 30, 1995, approximately $758,000 of the
restructuring charge was  unpaid  and  recorded  in  accrued  expenses  in  the
Consolidated Condensed Balance Sheet.  During the six months ended December 31,
1995,   the  Company  paid  the  remaining  $758,000,  the  majority  of  which
represented  fees  due  the Company's real estate broker in connection with the
termination of the lease.

(7)  OTHER INCOME

      During the quarter  ended  December  31,  1995, the Company recognized as
other income approximately $1,313,000, representing  the  unused  portion of an
advance  received  under  a  development  and  license  agreement  with  Sanofi
Winthrop,  Inc.  ("Sanofi").   During  October  1995,  the Company learned that
Sanofi intended to cease development of PEG-SOD (Dismutec) due to the product's
failure  to show a statistically significant difference between  the  treatment
group and  the  control  group  in a pivotal Phase III trial.  Due, in part, to
this product failure, the Company  believes it has no further obligations under
its agreement with Sanofi with respect to the $1,313,000 advance and therefore,
the Company has reversed the amount due Sanofi previously recorded as a current
liability.

(8)  SUBSEQUENT EVENT

      On  January 31, 1996, the Company  completed  a  private  placement  (the
"Private Placement")  of  Common Stock and Series B Convertible Preferred Stock
("Convertible Preferred Stock"),  resulting  in  gross  proceeds of $7,000,000,
with an institutional investor pursuant to Regulation D of  the  Securities Act
of 1933, as amended.  The Company issued 1,094,890 shares of Common  Stock  for
$3,000,000,  raising  the  outstanding  common  shares to 27,423,764 and 40,000
shares of Convertible Preferred Stock for $4,000,000.   The Company also issued
five-year warrants (the "Warrants") to purchase 638,686 shares  of Common Stock
at $4.11 per share.  The Convertible Preferred Stock is convertible  commencing
70  days  after  issuance.   The conversion price for the Convertible Preferred
Stock is 80% of the market price  for  the five consecutive trading days ending
one trading day prior to the date of the conversion notice and the stated value
is $100 per share.  The Convertible Preferred  Stock  will  not pay a dividend.
In connection with the Private Placement, the Company agreed  to  register on a
Registration  Statement  on  Form  S-3  the Common Stock issued, the shares  of
Common Stock underlying the Convertible Preferred  Stock,  the shares of Common
Stock  underlying the Warrants and certain shares of Common Stock  issuable  in
the event the Company does not comply with certain of its obligations under the
agreements.  The issuance of the Private Placement stock and warrants would not
have changed  the  net  loss  per  common  share reported for the three and six
months ended December 31, 1995.

ITEM 2.MANAGEMENT'S DISCUSSION AND ANALYSIS  OF FINANCIAL CONDITION AND RESULTS
      OF OPERATIONS

RESULTS OF OPERATIONS

THREE MONTHS ENDED DECEMBER 31, 1995 VS. THREE MONTHS ENDED DECEMBER 31, 1994

REVENUES.  Revenues for the three months ended  December  31, 1995 increased by
51% to $3,330,000 as compared to $2,202,000 for the same period  in  1994.  The
components of revenues are sales and contract revenues.  Sales increased by 21%
to  $2,542,000  for  the  three  months ended December 31, 1995 as compared  to
$2,102,000 for the same period in  the  prior  year,  due to increased revenues
from   ONCASPAR,  which  is  marketed  in  the  U.S.  by  Rhone-Poulenc   Rorer
Pharmaceuticals,  Inc.  ("RPR").   ADAGEN  sales  for  the  three  months ended
December  31,  1995  and  1994  were  $2,039,000  and $2,094,000, respectively.
Contract  revenue for the three months ended December  31,  1995  increased  to
$788,000, as  compared  to  $100,000 for the same period in 1994.  The increase
was principally due to a payment  received  in connection with the signing of a
worldwide non-exclusive licensing agreement with  RPR for the Company's Single-
Chain Antigen-Binding ("SCA") protein technology during  the three months ended
December 31, 1995.  During the three months ended December  31,  1995 and 1994,
the Company had export sales of $491,000 and $549,000, respectively.   Sales in
Europe were $429,000 and $466,000 for the three months ended December 31,  1995
and 1994, respectively.

COST  OF  SALES.  Cost of sales, as a percentage of sales, increased to 42% for
the three months ended December 31, 1995 as compared to 21% for the same period
in 1994.  The increase was due primarily to a payment in lieu of satisfying the
minimum purchase  requirements  under  the Company's long-term supply agreement
for a raw material used in the production  of  ONCASPAR  and  the  write-off of
excess  inventories of this raw material, as well as an increase in the  charge
recorded  for the three months ended December 31, 1995 for idle capacity at the
Company's manufacturing  facility.  During the quarter ended December 31, 1995,
the Company utilized approximately  21%  of  its manufacturing capacity for the
production of its approved products.

RESEARCH  AND DEVELOPMENT.  Research and development  expenses  for  the  three
months ended  December  31, 1995 decreased by 30% to $2,391,000 from $3,402,000
for the same period in 1994.  This decrease was primarily due to (i) reductions
in personnel, principally  in  the  clinical and research administration areas,
and related costs, such as payroll taxes  and benefits, (ii) decreased research
facilities and occupancy costs, and (iii) other cost containment measures taken
by the Company.

SELLING,   GENERAL   AND  ADMINISTRATIVE  EXPENSES.    Selling,   general   and
administrative expenses  for the three months ended December 31, 1995 decreased
by 25% to $1,404,000 from $1,872,000 for the same period in 1994.  The decrease
was due to (i) reductions in personnel and related costs, such as payroll taxes
and benefits, (ii) a reduction in facility and occupancy costs, and (iii) other
cost containment measures taken by the Company.

OTHER  INCOME/EXPENSE.   Other   income/expense   increased  by  $1,314,000  to
$1,396,000 for the three months ended December 31,  1995 as compared to $81,000
for  the  same  period  last  year.  The increase was due  principally  to  the
recognition as other income of approximately $1,313,000 representing the unused
portion of an advance received  under  a development and license agreement with
Sanofi Winthrop, Inc. ("Sanofi").  During  October  1995,  the  Company learned
that  Sanofi  intended  to cease development of PEG-SOD (Dismutec) due  to  the
product's failure to show  a  statistically  significant difference between the
treatment group and the control group in a pivotal  Phase  III  trial.  Due, in
part,  to  this  product  failure,  the  Company  believes  it  has  no further
obligations  under  its  agreement  with  Sanofi with respect to the $1,313,000
advance and therefore, the Company has recognized  as  other  income the amount
due Sanofi previously recorded as a current liability.


SIX MONTHS ENDED DECEMBER 31, 1995 VS. SIX MONTHS ENDED DECEMBER 31, 1994

REVENUES.  Revenues for the six months ended December 31, 1995  increased by 3%
to  $6,256,000  as  compared  to  $6,059,000 for the same period in 1994.   The
components of revenues are sales and contract revenues.  Sales increased by 29%
to  $5,351,000  for the six months ended  December  31,  1995  as  compared  to
$4,159,000 for the  same  period  in  the prior year, due to increased ONCASPAR
revenues from RPR and an increase in ADAGEN sales resulting from an increase in
patients receiving ADAGEN.  ADAGEN sales  for the six months ended December 31,
1995 and 1994 were $4,214,000 and $4,009,000,  respectively.   Contract revenue
for  the  six  months ended December 31, 1995 decreased by 52% to $905,000,  as
compared  to $1,900,000  for  the  same  period  in  1994.   The  decrease  was
principally due to a payment of $1,800,000 recorded during the six months ended
December 31,  1994  from  Bristol-Myers  Squibb  related to the exercise of its
option under an agreement dated September 1993, to  acquire  a  worldwide  non-
exclusive license for all therapeutic indications for the Company's SCA protein
technology.   This  decrease  was  offset  in part by a worldwide non-exclusive
license  for the Company's SCA protein technology  signed  with  RPR  in  1995.
During the  six months ended December 31, 1995 and 1994, the Company had export
sales of $1,131,000  and $999,000, respectively.  Sales in Europe were $983,000
and $871,000 for the six months ended December 31, 1995 and 1994, respectively.

COST OF SALES.  Cost of  sales,  as a percentage of sales, increased to 38% for
the six months ended December 31,  1995  as compared to 33% for the same period
in 1994.  The increase was due primarily to a payment in lieu of satisfying the
minimum purchase requirements under the Company's  long-term  supply  agreement
for  a  raw  material  used in the production of ONCASPAR and the write-off  of
excess inventories of this  raw  material, as well as an increase in the charge
recorded for the six months ended  December  31,  1995 for idle capacity at the
Company's  manufacturing  facility.  This increase was  offset  in  part  by  a
decrease in cost of sales as  a  percentage  of sales for the Company's product
ADAGEN.  ADAGEN's margins improved during the  six  months  ended  December 31,
1995,  due  to  the  elimination  of  inefficiencies experienced in the filling
process during the previous year.

RESEARCH AND DEVELOPMENT.  Research and development expenses for the six months
ended December 31, 1995 decreased by 25%  to $5,081,000 from $6,758,000 for the
same period in 1994.  This decrease was primarily  due  to  (i)  reductions  in
personnel,  principally  in the clinical and research administration areas, and
related costs, such as payroll  taxes  and  benefits,  (ii)  decreased research
facilities and occupancy costs, and (iii) other cost containment measures taken
by the Company.

SELLING,   GENERAL   AND   ADMINISTRATIVE   EXPENSES.   Selling,  general   and
administrative expenses for the six months ended December 31, 1995 decreased by
30% to $2,676,000 from $3,820,000 for the same  period  in  1994.  The decrease
was due to (i) reductions in personnel and related costs, such as payroll taxes
and benefits, (ii) a reduction in facility and occupancy costs, and (iii) other
cost containment measures taken by the Company.

OTHER INCOME/EXPENSE.  Other income/expense increased by $724,000 to $1,494,000
for the six months ended December 31, 1995 as compared to $771,000 for the same
period last year.  The increase was due principally to the recognition as other
income  of  approximately  $1,313,000  representing  the unused portion  of  an
advance received under a development and license agreement with Sanofi.  During
October 1995, the Company learned that Sanofi intended  to cease development of
PEG-SOD  (Dismutec)  due  to  the  product's  failure  to show a  statistically
significant difference between the treatment group and the  control  group in a
pivotal  Phase  III  trial.  Due, in part, to this product failure, the Company
believes it has no further  obligations  under  its  agreement with Sanofi with
respect to the $1,313,000 advance and therefore, the Company  has recognized as
other income the amount due Sanofi previously recorded as a current  liability.
Other  income/expense  in  the  prior  year principally consisted of a one-time
insurance payment recorded in the prior year.

LIQUIDITY AND CAPITAL RESOURCES

      Enzon had $5,309,000 in cash and cash  equivalents  as  of  December  31,
1995.   The  Company  invests  its  excess  cash  in  a portfolio of high-grade
marketable securities and United States government-backed securities.

      The  Company's  cash  reserves,  as  of December 31, 1995,  decreased  by
$2,794,000 from June 30, 1995.  The decrease in cash reserves was caused by the
funding of operations.

      The  Company's  exclusive U.S. marketing  rights  license  with  RPR  for
ONCASPAR provides for a  payment  of  $3,500,000 in advance royalties which was
received in January 1995.  Royalties due  under  the  revised agreement will be
offset  against a credit of $5,970,000, which represents  the  royalty  advance
plus reimbursement  of certain amounts due RPR under the previous agreement and
interest expense, before  cash  payments will be made under the agreement.  The
royalty  advance  is shown as a long  term  liability  with  the  corresponding
current portion included  in  accrued  expenses  on  the consolidated condensed
balance  sheets  and  will  be  reduced as royalties are recognized  under  the
agreement.

      As  of  December  31,  1995,  940,808   shares  of  Series  A  Cumulative
Convertible Preferred Stock ("Series A Preferred  Stock")  had  been  converted
into  3,093,411  shares  of  Common  Stock.  Accrued dividends on the converted
Series A Preferred Stock in the aggregate of $1,792,000  were  settled  by  the
issuance  of  232,383  shares  of Common Stock.  The Company does not presently
intend to pay cash dividends on  the  Series A Preferred Stock.  As of December
31, 1995, there were $1,258,000 of accrued and unpaid dividends on the Series A
Preferred Stock.  These dividends are payable  in  cash  or Common Stock at the
Company's option and accrue on the outstanding Series A Preferred  Stock at the
rate of $218,000 per year.

      To  date, the Company's sources of cash have been the proceeds  from  the
sale of its stock through public and private placements, sales of ADAGEN, sales
of ONCASPAR, sales of its products for research purposes, contract research and
development  fees,  technology  transfer and license fees and royalty advances.
The Company's current sources of  liquidity  are its cash, cash equivalents and
interest earned on such cash reserves, sales of  ADAGEN, sales of ONCASPAR, the
proceeds  of  the  Company's private placement of Common  Stock  and  Series  B
Convertible Preferred Stock described below, sales of its products for research
purposes and license  fees.   Management  believes  that its current sources of
liquidity will be sufficient to meet its anticipated  cash  requirements, based
on current spending levels, for approximately the next two years.

      On January 31, 1996, the Company completed a private placement  of Common
Stock and Series B Convertible Preferred Stock ("Convertible Preferred Stock"),
resulting  in  gross  proceeds  of  $7,000,000,  with an institutional investor
pursuant  to  Regulation  D of the Securities Act of  1933,  as  amended.   The
Company issued 1,094,890 shares  of  Common  Stock  for  $3,000,000, and 40,000
shares of Convertible Preferred Stock for $4,000,000.  The  Company also issued
five-year  warrants  to purchase 638,686 shares of Common Stock  at  $4.11  per
share.  The Convertible Preferred Stock is convertible commencing 70 days after
issuance.  The conversion  price  for the Convertible Preferred Stock is 80% of
the market price for the five consecutive  trading  days ending one trading day
prior to the date of the conversion notice and the stated  value  is  $100  per
share.  The Convertible Preferred Stock will not pay a dividend.

      Upon  exhaustion  of  the  Company's current cash reserves, the Company's
continued operations will depend on its ability to realize significant revenues
from the commercial sale of its products, raise additional funds through equity
or  debt financing, or obtain significant  licensing,  technology  transfer  or
contract  research  and development fees.  There can be no assurance that these
sales, financings or revenue generating activities will be successful.

                        The Preferred  Stock may be issued from time to time in
                  one  or  more  series.    The   board  of  Directors  of  the
                  Corporation  is hereby expressly authorized  to  provide,  by
                  resolution  or  resolutions  duly  adopted  by  it  prior  to
                  issuance, for the creation of each such series and to fix the
                  designation   and    the    powers,    preferences,   rights,
                  qualifications, limitations and restrictions  relating to the
                  shares  of each such series.  The authority of the  Board  of
                  Directors  with  respect  to  each  series of Preferred Stock
                  shall  include,  but  not  be  limited  to,  determining  the

                        (a)   the  designation of such series,  the  number  of
                  shares to constitute such series and the stated value thereof
                  if different from the par value thereof;

                        (b)   whether  the  shares  of  such  series shall have
                  voting rights, in addition to any voting rights  provided  by
                  law,  and,  if so, the terms of such voting rights, which may
                  be general or limited;

                        (c)   the  dividends,  if  any, payable on such series,
                  whether any such dividends shall be  cumulative,  and, if so,
                  from  what  dates,  the conditions and dates upon which  such
                  dividends shall be payable,  and  the  preference or relation
                  which such dividends shall bear to the dividends  payable  on
                  any shares of stock of any other class or any other series of
                  Preferred Stock;

                        (d)   whether  the  shares  of  such  series  shall  be
                  subject  to  redemption  by  the Corporation, and, if so, the
                  times, prices and other conditions of such redemption;

                        (e)   the amount or amounts payable upon shares of such
                  series upon, and the rights of the holders of such series in,
                  the  voluntary  or  involuntary liquidation,  dissolution  or
                  winding up, or upon any  distribution  of  the assets, of the
                  Corporation;

                        (f)   whether  the  shares  of  such  series  shall  be
                  subject to the operation of a retirement or sinking fund and,
                  if so, the extent to and manner in which any  such retirement
                  or  sinking  fund  shall  be  applied  to  the  purchase   or
                  redemption  of  the  shares  of such series for retirement or
                  other  corporation  purposes and  the  terms  and  provisions
                  relating to the operation thereof;

                        (g)   whether  the  shares  of  such  series  shall  be
                  convertible into, or exchangeable for, shares of stock of any
                  other class or any other  series  of  Preferred  Stock or any
                  other securities and, if so, the price or prices or  the rate
                  or rates of conversion or exchange and the method, if any, of
                  adjusting  the  same,  and any other terms and conditions  of
                  conversion or exchange;

                        (h)   the conditions  or restrictions, if any, upon the
                  creation of indebtedness of the Corporation or upon the issue
                  of any additional stock, including  additional shares of such
                  series or of any other series of Preferred  Stock  or  of any
                  other class; and

                        (i)   any   other  powers,  preferences  and  relative,
                  participating, optional  and  other  special  rights, and any
                  qualifications, limitations and restrictions, thereof.

                        The  powers,  preferences  and relative, participating,
                  optional and other special rights of each series of Preferred
                  Stock,  and the qualifications, limitations  or  restrictions
                  thereof,  if  any, may differ from those of any and all other
                  series at any time outstanding.  All shares of any one series
                  of Preferred Stock  shall  be  identical in all respects with
                  all other shares of such series,  except  that  shares of any
                  one  series  issued at different times may differ as  to  the
                  dates from which dividends thereof shall be cumulative.

            (b)   RESOLVED, that  an  additional Article, Article 9 be added to
                  the Certificate of Incorporation as set forth below:

                        "9.  The Board  of  Directors shall consist of not less
                  than three nor more than fifteen  directors, the exact number
                  of directors to be determined from time to time by resolution
                  adopted by affirmative vote of a majority  of the whole Board
                  of  Directors,  and  such  exact number shall be  four  until
                  otherwise  determined by resolution  adopted  by  affirmative
                  vote of a majority  of the whole Board of Directors.  As used
                  in this Article 9, the  term  "whole  Board"  means the total
                  number of directors which the Corporation would have if there
                  were no vacancies.  The Board of Directors shall  divide  the
                  directors   into  three  classes  and,  when  the  number  of
                  directors is changed, shall determine the class or classes to
                  which the increased or decreased number of directors shall be
                  apportioned;  provided,  that  no  decrease  in the number of
                  directors  shall  affect  the  term of any director  then  in
                  office.   Notwithstanding  the  foregoing,   and   except  as
                  otherwise required by law, whenever the holders of any one or
                  more  series of Preferred Stock shall have the right,  voting
                  separately  as a class, to elect one or more directors of the
                  Corporation,  the  terms of the director or directors elected
                  by such holders shall  expire  at  the next succeeding annual
                  meeting  of stockholders.  The term of  office  of  directors
                  elected at  the  1986  Annual Meeting of Stockholders held on
                  January 20, 1987 shall be  as follows:  the term of office of
                  directors of the first class shall expire at the first annual
                  meeting of stockholders after  their  election;  the  term of
                  office  of directors of the second class shall expire at  the
                  second annual  meeting  of stockholders after their election;
                  and the term of office of  directors of the third class shall
                  expire  at  the third annual meeting  of  stockholders  after
                  their election; and as to directors of each class, when their
                  respective successors  are  elected  and  qualified.  At each
                  annual meeting of stockholders subsequent to  the 1986 Annual
                  Meeting  of Stockholders, directors elected to succeed  those
                  whose terms  are  expiring  shall  be  elected  for a term of
                  office  to  expire at the third succeeding annual meeting  of
                  stockholders and when their respective successors are elected
                  and qualified.

                        Vacancies  in  the  Board of Directors, however caused,
                  and newly created directorships  shall  be filled solely by a
                  majority vote of the directors then in office, whether or not
                  a quorum, and any director so chosen shall  hold office for a
                  term expiring at the annual meeting of stockholders  at which
                  the  term  of the class to which the director has been chosen
                  expires and  when  the  director's  successor  is elected and
                  qualified.

                        The  affirmative vote of the holders of not  less  than
                  two-thirds of  the outstanding voting shares of capital stock
                  of the Corporation entitled to vote generally in the election
                  of directors shall  be  required  to  amend, alter, change or
                  repeal,  or  adopt  any  provisions  inconsistent  with  this
                  Article 9, provided, however, that this  paragraph  shall not
                  apply to, and such two-thirds vote shall not be required for,
                  any amendment, alteration, change, repeal or adoption  of any
                  inconsistent  provision  declared  advisable  by the Board of
                  Directors by the affirmative vote of two-thirds  of the Board
                  and  submitted  to stockholders for their consideration,  but
                  only if a majority  of  the members of the Board of Directors
                  acting upon such matter shall  be  Continuing Directors.  The
                  term "Continuing Director" shall mean  a  director  who was a
                  member of the Board as of October 1, 1986."

            (c)   RESOLVED, that an additional Article, Article 10 be added  to
                  the Certificate of Incorporation as set forth below:

                        "10.   A  director  of  the  Corporation  shall  not be
                  personally liable to the Corporation or its stockholders  for
                  monetary  damages for breach of fiduciary duty as a director,
                  except for  liability  (i)  for  any breach of the director's
                  duty of loyalty to the Corporation  or its stockholders, (ii)
                  for  acts  or omissions not in good faith  or  which  involve
                  intentional  misconduct  or a knowing violation of law, (iii)
                  under Section 174 of the Delaware General Corporation Law, as
                  the same exists or hereafter  may be amended, or (iv) for any
                  transaction  from  which  the director  derived  an  improper
                  personal benefit.  If the Delaware  General  Corporation  Law
                  hereafter  is amended to authorize the further elimination or
                  limitation of  the liability of directors, then the liability
                  of  a  director  of  the  Corporation,  in  addition  to  the
                  limitation on personal  liability  provided  herein, shall be
                  limited  to  the  fullest  extent  permitted  by the  amended
                  Delaware General Corporation Law.  Any repeal or modification
                  of  this  paragraph  by  the  stockholders of the Corporation
                  shall be prospective only, and shall not adversely affect any
                  limitation on the personal liability  of  a  director  of the
                  corporation   existing   at   the  time  of  such  repeal  or
                  modification."

            SECOND:  That at an annual meeting of stockholders the holders of a
majority of the outstanding stock entitled to vote  thereon  voted  in favor of
said amendments in accordance with the provisions of Section 216 of the General
Corporation Law of the State of Delaware.

            THIRD:    That  the  aforesaid  amendments  were  duly  adopted  in
accordance with the applicable  provisions  of  Sections  242  and  216  of the
General Corporation Law of the State of Delaware.

            IN WITNESS WHEREOF, said Enzon, Inc. has caused this certificate to
be  signed  by  Dr.  Abraham  Abuchowski, its President, and attested by Leslie
Charmatz, asst. secretary, this 20th day of February, 1987.

            Enzon, Inc., a corporation organized and existing under and by
virtue of the General Corporation Law of the State of Delaware, DOES HEREBY
CERTIFY:

            FIRST:  That the Board of Directors of said Corporation, at a
meeting of its members, adopted a resolution proposing and declaring advisable
the following amendments to the Certificate of Incorporation of said
Corporation:

            (a)   RESOLVED, that Article 4 of the Certificate of Incorporation
                  be amended as set forth below:

                        "4:  The total number of shares of capital stock which
                  the Corporation shall have authority to issue is twenty-one
                  million (21,000,000) shares, of which twenty million

                  designation and the powers, preferences, rights,
                  qualifications, limitations and restrictions relating to the
                  shares of each such series.  The authority of the Board of
                  Directors with respect to each series of Preferred Stock
                  shall include, but not be limited to, determining the

                  shares to constitute such series and the stated value thereof
                  if different from the par value thereof;

                  voting rights, in addition to any voting rights provided by
                  law, and, if so, the terms of such voting rights, which may
                  be general or limited;

                        (c)   the dividends, if any, payable on such series,
                  whether any such dividends shall be cumulative, and, if so,
                  from what dates, the conditions and dates upon which such
                  dividends shall be payable, and the preference or relation
                  which such dividends shall bear to the dividends payable on
                  any shares of stock of any other class or any other series of
                  Preferred Stock;

                        (d)   whether the shares of such series shall be

                  winding up, or upon any distribution of the assets, of the
                  Corporation;

                        (f)   whether the shares of such series shall be
                  subject to the operation of a retirement or sinking fund and,
                  if so, the extent to and manner in which any such retirement
                  or sinking fund shall be applied to the purchase or
                  redemption of the shares of such series for retirement or
                  other corporation purposes and the terms and provisions
                  relating to the operation thereof;

                        (g)   whether the shares of such series shall be
                  convertible into, or exchangeable for, shares of stock of any
                  other class or any other series of Preferred Stock or any
                  other securities and, if so, the price or prices or the rate
                  or rates of conversion or exchange and the method, if any, of
                  adjusting the same, and any other terms and conditions of
                  conversion or exchange;

                        (h)   the conditions or restrictions, if any, upon the
                  creation of indebtedness of the Corporation or upon the issue
                  of any additional stock, including additional shares of such
                  series or of any other series of Preferred Stock or of any
                  other class; and

                  participating, optional and other special rights, and any
                  qualifications, limitations and restrictions, thereof.

                        The powers, preferences and relative, participating,
                  optional and other special rights of each series of Preferred
                  Stock, and the qualifications, limitations or restrictions
                  thereof, if any, may differ from those of any and all other
                  series at any time outstanding.  All shares of any one series
                  of Preferred Stock shall be identical in all respects with
                  all other shares of such series, except that shares of any
                  one series issued at different times may differ as to the
                  dates from which dividends thereof shall be cumulative.

            SECOND:  That at an annual meeting of stockholders the holders of a
majority of the outstanding stock entitled to vote thereon voted in favor of
said amendments in accordance with the provisions of Section 216 of the General
Corporation Law of the State of Delaware.

            THIRD:  That the aforesaid amendments were duly adopted in
accordance with the applicable provisions of Sections 242 and 216 of the

            IN WITNESS WHEREOF, said Enzon, Inc. has caused this certificate to

                                PREFERRED STOCK

                                      OF

                                  ENZON, INC.


            ENZON, Inc. (the "Company"),  a  corporation organized and existing

under the General Corporation Law of the State of Delaware, does hereby certify

that,  pursuant  to authority conferred upon the  Board  of  Directors  of  the

Company by the Certificate  of  Incorporation,  as amended, of the Company, and

pursuant  to  Section  151  of the General Corporation  Law  of  the  State  of

Delaware, the Board of Directors of the Company at a meeting duly held on March

9, 1990, adopted resolutions  providing  for  the designations, preferences and

relative,  participating,  optional or other rights,  and  the  qualifications,

limitations or restrictions  thereof,  of  one  million  one  hundred  thousand

(1,100,000)  shares  of  Series  A  Cumulative Convertible Preferred Stock (the

"Preferred Shares") of the Company, as follows:

      RESOLVED, that the Preferred Shares  shall  have  the  following  powers,
      designations, preferences and other special rights:

            DIVIDENDS. The holders of the Preferred Shares shall be entitled to
      an  annual dividend of $2.00 per Share (pro-rated for any portion of  the
      applicable  period  during  which  the Preferred Shares are outstanding),
      payable semi-annually on December 15  and  June 15 of each year, but only
      when  and  if declared by the Board of Directors  out  of  funds  legally
      available  therefor.    Dividends   on  the  Preferred  Shares  shall  be
      cumulative from and after the date of issuance of such Shares.  Dividends
      will accrue and accumulate but will not  be  paid  until such time as the
      Board of Directors deems it appropriate in light of  the  Company's  then
      current  financial  condition.   Any  accumulation  of  dividends  on the
      Preferred Shares shall not bear interest.  No dividends shall be paid  or
      set  apart for payment on the Company's common stock, par value, $.01 per
      share  (the  "Common  Stock"),  nor shall any distribution be made on the
      Common Stock (other than a dividend  payable  in  Common  Stock or in any
      other class of stock ranking junior to the Preferred Shares),  nor  shall
      any shares of Common Stock be redeemed, retired or otherwise acquired for
      valuable  consideration  unless  the  Company shall have paid in full, or
      made appropriate provision for the payment  in  full  of,  all  dividends
      which  have then accumulated on the Preferred Shares.  In the event  that
      the  Company   does  not  make  cash  dividend  payments  for  eight  (8)
      semi-annual periods  from  the  date of issuance of the Preferred Shares,
      any holder of the Preferred Shares  may elect, upon written notice to the
      Company, to be paid all or any part of such accrued and unpaid dividends,
      and any dividends which accrue but are  unpaid  thereafter,  in shares of
      the  Company's  Common  Stock.   In  the  event of such an election,  the
      Company shall, to the extent it may legally  do  so, issue and deliver to
      any  holder  of  Preferred Shares who so elects to be  paid  its  accrued
      dividends in Common  Stock,  within  thirty (30) days after the Company's
      receipt  of  such  holder's  notice  to  so   elect,   a  certificate  or
      certificates representing such Common Stock registered in  such  holder's
      name.   Accrued  and  unpaid  dividends  payable  to holders of Preferred
      Shares as of the date such holder elects to convert  the Preferred Shares
      into Common Stock may, at the Company's option, be paid  by the Company's
      issuance of Common Stock to such holder.  In order to exercise its option
      to so pay accrued dividends upon conversion of the Preferred  Shares  the
      Company  shall so notify the holder of such Preferred Shares, in writing,
      within twenty  (20)  days after such holder's conversion of its Preferred
      Shares and shall issue  and  deliver  to  such holder, within thirty (30)
      days  after  such  holder's  conversion  of  its   Preferred   Shares,  a
      certificate or certificates representing such Common Stock registered  in
      such  holder's  name.  In all cases, the number of shares of Common Stock
      to be received in  lieu  of  accrued  dividends  shall  be  determined by
      dividing the aggregate amount of the accrued and unpaid dividends  by the
      conversion  price  of  the  Preferred  Shares  in  effect  on the date of
      election.  Any accrued dividends paid by the Company's delivery of Common
      Stock shall be deemed to be paid in full for all purposes.

            CONVERSION OF PREFERRED SHARES. The holders of the Preferred Shares
      shall have the right, at their option, to convert such Shares into shares
      of Common Stock on the following terms and conditions:

                  (a)  Each Preferred Share shall be convertible at  any  time
            (or, if such Share is called for redemption, at any time up to and
            including, but  not after, the close of business on the fifth full
            business day prior  to  the date fixed for such redemption, unless
            default shall be made by  the  Company  in providing the funds for
            the  payment  of  the  redemption  price),  into  fully  paid  and
            nonassessable shares (calculated to the nearest  whole  share)  of
            Common  Stock  of  the  Company as constituted at the time of such
            conversion, at the conversion  price  in  effect  at  the  time of
            conversion  determined  as  hereinafter  provided.  Each Preferred
            Share  shall  have  a  value  of  $25  for  the  purpose  of  such
            conversion.   Every reference herein to the Common  Stock  of  the
            Company (unless  a  different  intention is expressed) shall be to
            the shares of the Common Stock of  the Company, $.01 par value, as
            such stock exists immediately after  the issuance of the Preferred
            Shares provided for hereunder, or to stock  into which such Common
            Stock may be changed from time to time thereafter.

                  (b) Commencing on the date of issuance  each Preferred Share
            shall  be  convertible into Common Stock at an initial  conversion
            price  of  $7.50  per  share  of  Common  Stock  until  the  first
            anniversary  of  issuance, and will thereafter be convertible at a
            price  calculated  on  each  subsequent  anniversary  as  follows:
            Commencing on the first  anniversary  of  issuance, each Preferred
            Share will be convertible at a price of $7.875 per share of Common
            Stock;  commencing  on the second anniversary  of  issuance,  each
            Preferred Share will  be convertible at a price of $8.27 per share
            of Common Stock; commencing  on  the third anniversary of issuance
            each Preferred Share will be convertible  at  a price of $9.10 per
            share  of  Common Stock; commencing on the fourth  anniversary  of
            issuance each  Preferred  Share  will be convertible at a price of
            $10.00 per share of Common Stock;  and  commencing  on  the  fifth
            anniversary  of  issuance and thereafter each Preferred Share will
            be convertible at  a  price  of  $11.00 per share of Common Stock.
            Notwithstanding the foregoing, the  initial  conversion  price set
            forth  above shall not increase unless and until at the time  such
            increase was to have occurred, the Company shall have obtained the
            effectiveness  of  the  registration  of the Common Stock issuable
            under  the  conversion  terms  set  forth above  (the  "Underlying
            Shares") under the Securities Act of  1933,  as amended; PROVIDED,
            HOWEVER, that such increase in the conversion price shall occur if
            the delay in obtaining the effectiveness of such  registration was
            due  to  the  Purchaser's  failure  to provide the information  or
            indemnification required under Section 5 of the Stock Subscription
            Agreement dated as of March 20, 1990,  on  file  with the Company;
            and, FURTHER PROVIDED, HOWEVER, that in the event  of such a delay
            in the increase of the conversion price, the conversion price will
            increase  immediately upon the effectiveness of such  registration
            of the Underlying  Shares to the conversion price which would have
            otherwise then been in effect under the terms set forth above.

                  (c) If at any  time, or from time to time, the Company shall
            (i) declare and pay, on  or  in  respect  of, its Common Stock any
            dividend payable in shares of Common Stock  or  (ii) subdivide the
            outstanding  shares  of  Common  Stock  into a greater  number  of
            shares, or reduce the number of outstanding  Preferred  Shares  by
            combining  such  Shares  into  a  smaller  number  of  Shares, the
            conversion price in effect at the time of the taking of  a  record
            for  such  dividend  or  the  taking of such other action shall be
            proportionately decreased as of such time, and conversely (iii) if
            at any time, or from time to time,  the  Company  shall reduce the
            number  of  outstanding  shares of Common Stock by combining  such
            shares  into  a  smaller  number   of  shares,  or  subdivide  the
            outstanding Preferred Shares into a  greater  number  of Preferred
            Shares,  the conversion price in effect at the time of the  taking
            of any such  action  shall be proportionately increased as of such
            time.

                  (d) If the Company  shall consolidate with or merge into any
            corporation or reclassify its  outstanding  shares of Common Stock
            (other than by way of subdivision or reduction  of  such  shares),
            each  Preferred  Share  shall  thereafter  be convertible into the
            number of shares of stock or other securities  or  property of the
            Company,  or  of  the entity resulting from such consolidation  or
            merger, to which a  holder of the number of shares of Common Stock
            delivered upon conversion  of such Preferred Share would have been
            entitled upon such consolidation  or  merger  or reclassification,
            had  the  holder of such Preferred Share exercised  its  right  of
            conversion  and  had such Common Stock been issued and outstanding
            and had such holder been the holder of record of such Common Stock
            at the time of such consolidation, merger or reclassification; and
            the Company shall make lawful provision therefor as a part of such
            consolidation, merger or reclassification.

                  (e) The Company  shall not be required to give effect to any
            adjustment in the conversion price unless and until the net effect
            of one or more adjustments,  determined  as  above provided, shall
            have  resulted  in a change of the conversion price  by  at  least
            $0.50, PROVIDED,  HOWEVER,  that when the cumulative net effect of
            more than one adjustment so determined  shall  be  to  change  the
            conversion  price  by at least $0.50 such change in the conversion
            price shall thereupon be given effect.

                  (f) Whenever the  conversion  price  is  adjusted, as herein
            provided,  the Company shall promptly deliver to  each  holder  of
            Preferred Shares  and  file  with  the  records  of  the Company a
            statement signed by the Company's Chief Financial Officer  setting
            forth  the  adjusted  conversion price, determined as so provided.
            Such statement shall set  forth in reasonable detail such facts as
            may  be  necessary  to show the  reason  for  and  the  manner  of
            computing such adjustment.

                  (g) The Company  shall  not issue any fraction of a share of
            Common Stock upon any conversion,  but  shall pay in cash therefor
            at  the  conversion  price  then  in  effect  multiplied  by  such
            fraction.

                  (h) On presentation and surrender to the  Company  or at any
            office  or  agency  maintained  for  the transfer of the Preferred
            Shares of the certificates of Preferred Shares so to be converted,
            duly  endorsed  in  blank for transfer or  accompanied  by  proper
            instruments of assignment  or  transfer  in blank, with signatures
            guaranteed, the holder of such Preferred Shares shall be entitled,
            subject  to  the  limitations  herein  contained,  to  receive  in
            exchange therefor a certificate or certificates for fully paid and
            nonassessable shares, and cash for fractional  shares,  of  Common
            Stock  on  the  foregoing  basis.   The  Preferred Shares shall be
            deemed to have been converted and the person  converting  the same
            to  have  become  the  holder  of  record of Common Stock, for the
            purpose of receiving dividends and for  all  other  purposes as of
            the  date when the certificate or certificates for such  Preferred
            Shares  are  surrendered to the Company as aforesaid.  The Company
            shall  not  be required  to  make  any  such  conversion,  and  no
            surrender of  the  Preferred  Shares  shall  be effective for such
            purpose,  while  the  books  for the transfer of either  Preferred
            Shares  or  Common  Stock are closed  for  any  purpose,  but  the
            surrender  of such Preferred  Shares  for  conversion  during  any
            period while  such books are closed shall become effective for all
            purposes of conversion  immediately  upon  the  reopening  of such
            books,  as  if  the  conversion  had  been  made  on the date such
            Preferred Shares were surrendered.

                  (i)  The  Company  shall,  so  long as any of the  Preferred
            Shares  are outstanding, reserve and keep  available  out  of  its
            authorized  and  unissued  Common Stock, solely for the purpose of
            effecting the conversion of  the  Preferred Shares, such number of
            shares of Common Stock as shall from time to time be sufficient to
            effect  the  conversion  of  all  of  the  Preferred  Shares  then
            outstanding.

                  (j) The Company shall pay any and  all  taxes  which  may be
            imposed  upon  it  with  respect  to  the issuance and delivery of
            Common Stock upon the conversion of the Preferred Shares as herein
            provided.  The Company shall not be required  in  any event to pay
            any  transfer  or  other taxes by reason of the issuance  of  such
            Common Stock in names  other  than  those  in  which the Preferred
            Shares surrendered for conversion are registered  on the Company's
            records, and no such conversion or issuance of Common  Stock shall
            be  made unless and until the person requesting such issuance  has
            paid to the Company the amount of any such tax, or has established
            to the satisfaction of the Company and its transfer agent, if any,
            that  such  tax  has  been paid.  Upon any conversion of Preferred
            Shares as herein provided no adjustment or allowance shall be made
            for dividends on the Preferred Shares so converted, and all rights
            to dividends which would  otherwise  accrue subsequent to the date
            of  conversion,  if  any,  shall cease and  be  deemed  satisfied,
            PROVIDED, HOWEVER, that subject  to  the  Company's  right  to pay
            accrued  and  unpaid  dividends  by  the  issuance of Common Stock
            discussed above, nothing shall be deemed to  relieve  the  Company
            from  its obligation to pay any dividends which shall have accrued
            but remain unpaid to holders of Preferred Shares of record as of a
            date prior  to  such  conversion  even though the payment date for
            such dividend is subsequent to the date of conversion.
            VOTING RIGHTS. Preferred Shares may  be  voted  for the election of
      Directors  and  all  other  corporate matters upon which the  holders  of
      Common  Stock have the right to  vote.   Each  Preferred  Share  will  be
      entitled  to  one  vote.   Except  as  otherwise provided herein, for the
      purpose  of determining a quorum or the vote  on  any  such  matters  the
      Preferred  Shares  and  Common  Stock  will  be deemed to be one class of
      voting stock.  Holders of Preferred Shares shall  have  all  of  the same
      rights  to receive notice of and call meetings of stockholders as holders
      of the Common Stock.

            REDEMPTION.   The  Company may, at any time subsequent to the fifth
      anniversary of the issuance  thereof, redeem the whole or any part of the
      Preferred Shares then outstanding  at  a  redemption  price of $25.00 per
      Preferred  Share,  plus  in each case a sum equal to all accumulated  and
      unpaid  dividends thereon through  the  date  fixed  for  redemption,  in
      accordance with the following redemption procedures:

                  (a)  In  case  of  redemption  of only part of the Preferred
            Shares at any time outstanding, the Company  shall  designate  the
            amount of Preferred Shares so to be redeemed and shall redeem such
            Preferred  Shares on a PRO RATA basis.  Subject to the limitations
            and provisions herein contained, the Board of Directors shall have
            the power and authority to prescribe the terms and conditions upon
            which the Preferred Shares shall be redeemed from time to time.

                  (b) Notice  of  every  redemption  shall be given by mail to
            every  holder  of  record  of  any  Preferred Shares  then  to  be
            redeemed, at least thirty (30), but no more than ninety (90), days
            prior to the date fixed as the date for the redemption thereof, at
            the respective addresses of such holders  as the same shall appear
            on  the  stock transfer books of the Company.   The  notice  shall
            state that  the  Preferred Shares shall be redeemed by the Company
            at the redemption  price  of $25.00 per share, plus a sum equal to
            all accumulated and unpaid  dividends  thereon  through  the  date
            fixed  for redemption, upon the surrender for cancellation, at the
            time and  place  designated  in  such  notice, of the certificates
            representing  the  Preferred  Shares  to  be   redeemed,  properly
            endorsed   in  blank  for  transfer,  or  accompanied  by   proper
            instruments  of  assignment and transfer in blank, with signatures
            guaranteed, and bearing  all necessary transfer tax stamps thereto
            affixed and cancelled.  On  and  after  the  date specified in the
            notice described above, each holder of Preferred Shares called for
            redemption  shall  be entitled to receive therefor  the  specified
            redemption price upon  presentation  and  surrender  at  the place
            designated in such notice of the certificates for Preferred Shares
            called for redemption, properly endorsed in blank for transfer  or
            accompanied  by  proper  instruments  of assignment or transfer in
            blank,  with  signatures  guaranteed, and  bearing  all  necessary
            transfer tax stamps thereto affixed and cancelled.

                  (c)  If  the Company shall  give  notice  of  redemption  as
            aforesaid (and unless the Company shall fail to pay the redemption
            price  of  the  Preferred   Shares  presented  for  redemption  in
            accordance with such notice),  all  Preferred  Shares  called  for
            redemption  shall  be  deemed  to  have  been redeemed on the date
            specified in such notice, whether or not the certificates for such
            Preferred  Shares shall be surrendered for  redemption,  and  such
            Preferred Shares  so  called  for  redemption shall from and after
            such  date  cease  to  represent any interest  whatsoever  in  the
            Company or its property,  and  the  holders  thereof shall have no
            rights  other  than  the  right  to receive such redemption  price
            without any interest thereon from and after such date.
                  (d)  Notwithstanding  the  foregoing,   if  such  notice  of
            redemption shall have been duly given as herein  provided  in this
            section  or  if  the  Company  shall have given to a bank or trust
            company irrevocable authorization  to give or complete such notice
            as herein provided, and if prior to  the redemption date specified
            in such notice the funds necessary for  such redemption shall have
            been deposited by the Company with a bank or trust company in good
            standing, organized under the laws of the United States of America
            or  the  State  of  New  York,  and  having capital,  surplus  and
            undivided profits aggregating at least  $50,000,000  according  to
            its  last published statement of condition, in trust to be applied
            to the  redemption  of the Preferred Shares called for redemption,
            and such notice shall  state that such deposit has taken place and
            the date thereof, then notwithstanding  that  any  certificate for
            such  Preferred  Shares  shall  not  have  been  surrendered   for
            redemption,  from  and  after  the  time  of such deposit all such
            Preferred  Shares  so  called for redemption shall  no  longer  be
            deemed to be outstanding  and  all  rights  with  respect  to such
            Preferred Shares shall forthwith cease and terminate, except  only
            the  right  of  the  holders  thereof to receive from such bank or
            trust company at any time after the time of such deposit the funds
            so deposited, without interest,  and  the  right  of  the  holders
            thereof  to convert the Preferred Shares as discussed above.   Any
            funds so set aside or deposited, as the case may be, and unclaimed
            one day prior  to  the end of three (3) years from such redemption
            date shall be released  or  repaid to the Company, after which the
            holders of the Preferred Shares  called  for redemption shall look
            only to the Company for payment thereof.   Any interest accrued on
            any funds so deposited shall be paid to the  Company  from time to
            time; and no such holder shall have any right thereto.

            LIQUIDATION,  DISSOLUTION,  WINDING  UP.   In  the  event  of   any
      voluntary  or  involuntary  liquidation, dissolution or winding up of the
      Company, the holders of the Preferred Shares shall be entitled to receive
      in cash out of the assets of  the  Company,  whether from capital or from
      earnings,  available  for  distribution to its stockholders,  before  any
      amount shall be paid to the  holders  of the Common Stock, the sum of $25
      per Preferred Share, plus an amount equal  to  all accumulated and unpaid
      dividends thereon through the date fixed for payment of such distributive
      amount.  The purchase or redemption by the Company of stock of any class,
      in any manner permitted by law, shall not, for the  purposes  hereof,  be
      regarded  as  a  liquidation,  dissolution  or winding up of the Company.
      Neither  the consolidation nor merger of the Company  with  or  into  any
      other corporation  or  corporations,  nor  the  sale  or  transfer by the
      Company of all or any part of its assets, shall, for the purposes hereof,
      be deemed to be a liquidation, dissolution or winding up of  the Company.
      No  holder  of Preferred Shares shall be entitled to receive any  amounts
      with respect  thereto  upon any liquidation, dissolution or winding up of
      the Company other than the amounts provided for herein.

            PREFERRED RANK.  All shares of Common Stock shall be of junior rank
      to all Preferred Shares  in  respect  of the preferences as to dividends,
      distributions and payments upon the liquidation,  dissolution  or winding
      up  of  the  Company.  The rights of the shares of Common Stock shall  be
      subject to the  preferences  and relative rights of the Preferred Shares.
      Notwithstanding  the foregoing,  the  Company  may  authorize  and  issue
      additional or other  preferred  stock  which  is  of  equal rank with the
      Preferred   Shares  in  respect  of  the  preferences  as  to  dividends,
      distributions  and  payments upon the liquidation, dissolution or winding
      up of the Company; PROVIDED,  HOWEVER,  that for so long as the Preferred
      Shares remain outstanding the Company shall  not  issue any capital stock
      which is more senior in rank than the Preferred Shares  in respect of the
      foregoing preferences or which shall have greater voting  rights than the
      Preferred  Shares.   In  the  event of a merger or consolidation  of  the
      Company  with or into another corporation,  the  Preferred  Shares  shall
      maintain their relative powers, designations and preferences provided for
      herein.

            VOTE TO CHANGE PREFERRED SHARES.  The affirmative vote at a meeting
      duly called  for such purpose or the written consent without a meeting of
      the holders of not less than two-thirds (66 2/3%) of the then outstanding
      Preferred Shares  shall be required to amend, alter, change or repeal any
      of the powers, designations,  preferences  and  rights  of  the Preferred
      Shares.


            IN WITNESS WHEREOF, the Company has caused this certificate  to  be

signed  by  Abraham  Abuchowski, its Chief Executive Officer and President, and

John Caruso, its Secretary, this 21st day of March, 1990.

      ENZON,  Inc. (the "COMPANY"), a corporation organized and existing  under

pursuant to authority  conferred  upon the Board of Directors of the Company by

the Certificate of Incorporation, as  amended,  of the Company, and pursuant to

            Shares shall not be entitled to dividends.

                  (2)   CONVERSION OF SERIES B PREFERRED  SHARES.   The holders
            of  the  Series  B Preferred Shares shall have the right, at  their
            option, to convert  the  Series  B  Preferred Shares into shares of
            Common Stock on the following terms and conditions:

                        (a)   Each Preferred Share  shall be convertible at any
            time after seventy (70) days after the date  of  issuance  (or,  if
            such Series B Preferred Share is called for redemption, at any time
            up  to  and  including, but not after, the close of business on the
            fifth  full  business   day  prior  to  the  date  fixed  for  such
            redemption,  unless  default  shall  be  made  by  the  Company  in

            fully paid and nonassessable  shares  (calculated  to  the  nearest
            whole  share) of Common Stock of the Company as constituted at  the
            time of  such  conversion, at the conversion price (the "CONVERSION
            PRICE")  in  effect   at  the  time  of  conversion  determined  as
            hereinafter provided; PROVIDED, HOWEVER, that in no event shall any
            holder be entitled to convert  Series  B Preferred Shares if, after
            giving effect to such conversion, the number  of  shares  of Common
            Stock purchased pursuant to the Securities Purchase Agreement dated
            January  31,  1996  by  and among the Company and certain investors

            Warrants or issued on exercise of such Warrants,  or  conversion of
            Series B Preferred Shares and beneficially owned by such holder and
            all  other  holders  whose  holdings would be aggregated with  such
            holder  for  purposes  of  calculating   beneficial   ownership  in
            accordance  with  Sections 13(d) and 16 of the Securities  Exchange
            Act of 1934, as amended,  and the regulations thereunder ("SECTIONS
            13(D) AND 16"), including,  without  limitation, any person serving
            as an adviser to any holder (collectively,  the "RELATED PERSONS"),
            would exceed four and nine-tenths percent (4.9%) of the outstanding
            shares  of  Common  Stock (calculated in accordance  with  Sections
            13(d) and 16).  Common  Stock  issuable upon conversion of Series B
            Preferred Shares or exercise of  the  warrants  for the purchase of
            Common Stock held by such holder or the Related Persons  shall  not
            be  deemed  to  be beneficially owned by such holder or the Related
            Persons for this purpose.   Each Preferred Share shall have a value
            of $100 (the "STATED VALUE") for the purpose of such conversion and
            the number of shares  of  Common  Stock issuable upon conversion of
            each  of  the  Series B Preferred Shares  shall  be  determined  by
            dividing the Stated  Value  thereof by the Conversion Price then in
            effect.  Every reference herein  to the COMMON STOCK of the Company
            (unless a different intention is expressed)  shall be to the shares
            of the Common Stock of the Company, $.01 par value,  as  such stock
            exists  immediately  after  the  issuance of the Series B Preferred
            Shares provided for hereunder, or  to  stock into which such Common
            Stock may be changed from time to time thereafter.

                        (b)   The  Conversion  Price shall  be  eighty  percent
            (80%) (the "CONVERSION PERCENTAGE") of the Average Market Price (as
            defined below) for the Common Stock  for  the  five (5) consecutive
            trading  days  ending  one  trading  day  prior  to  the  date  the
            Conversion  Notice  (as defined below) is received by the  Company,

            statement  (the  "REGISTRATION STATEMENT") covering the  shares  of
            Common Stock issuable  upon  conversion  of  the Series B Preferred

            and Exchange Commission ("SEC") within ninety (90) days  after  the
            date of issuance of the Series B Preferred Shares, or if, after the
            Registration  Statement  has  been  declared  effective by the SEC,
            sales  cannot  be  made pursuant to the Registration  Statement  by
            reason  of  stop  order,   the  Company's  failure  to  update  the
            Registration Statement or otherwise,  or if the Common Stock is not
            listed  or included for quotation on the  National  Association  of
            Securities  Dealers  Automated Quotation ("NASDAQ") National Market
            System  (the  "NASDAQ-NMS"),  the  New  York  Stock  Exchange  (the
            "NYSE"), the American  Stock  Exchange  (the "AMEX"), or the NASDAQ
            SmallCap Market (the "NASDAQ SMALLCAP") then, as partial relief for
            the  damages  to  the  holder by reason of any  such  delay  in  or
            reduction of its ability  to sell the shares of Common Stock (which
            remedy shall not be exclusive  of  any  other remedies available at
            law or in equity, except that such remedy  shall  be  the exclusive
            remedy  for  any  delay  in  the  effectiveness of the Registration
            Statement provided the Registration Statement is declared effective
            by the SEC within 180 days after the date of issuance of the Series
            B Preferred Shares), the Conversion  Percentage shall be reduced by
            a number of percentage points equal to  three (3) times the sum of:
            (i) the number of months (prorated for partial  months)  after  the
            end  of  such  90 day period and prior to the date the Registration
            Statement is declared effective by the SEC, provided, however, that
            there shall be excluded from such period (and from any period under
            clause (ii) immediate  below)  delays  which  are  attributable  to
            changes in the Registration Statement required by the Investors (as
            that  term  is  defined  in  the  Registration  Rights  Agreement),
            including, without limitation, changes in the plan of distribution;
            (ii) the number of months (prorated for partial months) that  sales
            cannot be made pursuant to the Registration Statement (by reason of
            stop  order,  the  Company's  failure to update the Registration or
            otherwise)  after  the Registration  Statement  has  been  declared
            effective; and (iii)  the  number  of  months (prorated for partial
            months)  that  the  Common  Stock  is not listed  or  included  for
            quotation on the NASDAQ-NMS, NYSE, AMEX,  or  NASDAQ SmallCap after
            the  Registration  Statement has been declared effective;  provided
            that the aggregate number  of  months  that  are  the  basis  of  a
            reduction  in  the  Conversion Percentage pursuant to the foregoing
            clauses (i), (ii) and  (iii)  shall  not  exceed twelve (12).  (For
            example, if the Registration Statement becomes  effective  one  and
            one-half  (1  1/2 ) months after the end of such 90 day period, the
            Conversion  Percentage   would   be   75.5%  until  any  subsequent
            adjustment; if thereafter sales could not  be  made pursuant to the
            Registration  Statement  for  a  period  of  two  (2)  months,  the
            Conversion Percentage would then be 69.5%.)  If the holder converts
            Series  B  Preferred Shares into Common Stock and an adjustment  to
            the  Conversion   Percentage   is   required   subsequent  to  such
            conversion,  but  prior to the sale of such Common  Stock  by  such
            holder, the Company  shall pay to such holder, within five (5) days
            after receipt of a notice  of  the  sale  of such Common Stock from
            such holder, an amount equal to the Average  Market  Price  of  the
            Common  Stock  obtained  upon conversion of such Series B Preferred
            Shares for the five (5) trading  days  ending  one  (1) trading day
            prior  to  the  date  of  conversion multiplied by three-hundredths
            (.03) times the number of months  (prorated for partial months) for
            which  an  adjustment  was required; provided  that  the  aggregate
            number of months for which  such  an  adjustment  is required (when
            added  to  the  number  of months for which an adjustment  is  made
            pursuant to clauses (i),  (ii)  and  (iii)  above) shall not exceed
            twelve (12).  Such amount may be paid at the  Company's  option  in
            cash  or  Common  Stock valued based on the Average Market Price of
            the Common Stock for  the  period  of  five (5) consecutive trading
            days ending on the date of the sale of such Common Stock; PROVIDED,
            HOWEVER, that any amounts due as to that  period  during  which the
            shares  are not traded or included for quotation on the NASDAQ-NMS,
            NYSE, AMEX or NASDAQ SmallCap shall be paid in cash only; PROVIDED,
            FURTHER, HOWEVER, that in no event shall shares be issued hereunder
            if, after  giving  effect to such issuance, the number of shares of
            Common  Stock  purchased   pursuant   to  the  Securities  Purchase
            Agreement or issued on exercise of the  Warrants  or  conversion of
            the Series B Preferred Shares and beneficially owned by such holder
            and  all Related Persons would exceed four and nine-tenths  percent
            (4.9%)  of  the  outstanding  shares of Common Stock (calculated in
            accordance with Sections 13(d)  and  16; cash shall be paid in lieu
            of  any  shares  which  cannot be issued pursuant  to  this  second
            proviso.   Common  Stock  issuable  upon  conversion  of  Series  B
            Preferred Shares or exercise  of  the  warrants for the purchase of
            Common Stock held by such holder or the  Related  Persons shall not
            be  deemed to be beneficially owned by such holder or  the  Related
            Persons   for   this  purpose.  (For  example,  if  the  Conversion
            Percentage was 75.5%  at  the  time  of conversion of $1,000,000 in
            Stated Value of Series B Preferred Shares  (such  that the Series B
            Preferred Shares were converted into Common Stock having an Average
            Market Price for the applicable period in aggregate  of $1,324,503)
            and  subsequent  to  conversion  there was a further two (2)  month
            delay in the Registration Statement's being declared effective, and
            such Common Stock was sold at the end of such two (2) month period,
            the Company would pay to the holder  $79,470.20  in  cash or Common
            Stock.)

                        "AVERAGE MARKET PRICE" of any security for  any  period
            shall  be  computed  as  the  arithmetic average of the closing bid
            prices for such security for each trading day in such period on the
            NASDAQ-NMS, or, if the NASDAQ-NMS  is  not  the  principal  trading
            market for such security, on the principal trading market for  such
            security,  or, if market value cannot be calculated for such period
            on any of the foregoing bases, the average fair market value during
            such period  as reasonably determined in good faith by the Board of
            Directors of the Company.

                        (c)   If  the  Company  shall consolidate with or merge
            into any corporation or reclassify its outstanding shares of Common
            Stock  (other  than  by way of subdivision  or  reduction  of  such
            shares) (each a "MAJOR  TRANSACTION"), then each Series B Preferred
            Share shall thereafter be  convertible into the number of shares of
            stock or securities (the "RESULTING SECURITIES") or property of the
            Company,  or of the entity resulting  from  such  consolidation  or
            merger, to  which  a holder of the number of shares of Common Stock
            delivered upon conversion  of  such  Series B Preferred Share would
            have been entitled upon such Major Transaction  had  the  holder of
            such Series B Preferred Share exercised its right of conversion and
            had  such  Common  Stock  been  issued and outstanding and had such
            holder been the holder of record  of  such Common Stock at the time
            of  such  Major  Transaction,  and the Company  shall  make  lawful
            provision  therefor  as a part of  such  consolidation,  merger  or
            reclassification; PROVIDED,  HOWEVER,  that  the Company shall give
            the holders of the Series B Preferred Shares written  notice of any
            Major  Transaction  promptly  upon  the  execution of any agreement
            whether or not binding in connection therewith  (including  without
            limitation a letter of intent or agreement in principle) and  in no
            event shall a Major Transaction be consummated prior to ninety (90)
            days after such notice.

                        (d)   The  Company  shall  not  issue any fraction of a
            share of Common Stock upon any conversion, but  shall  pay  in cash
            therefor at the Conversion Price then in effect multiplied by  such
            fraction.

                        (e)   On  presentation and surrender to the Company (or
            at any office or agency maintained for the transfer of the Series B
            Preferred Shares) of the  certificates of Series B Preferred Shares
            so  to  be  converted,  duly endorsed  in  blank  for  transfer  or
            accompanied by proper instruments  of  assignment  or  transfer  in
            blank  (a  "CONVERSION  NOTICE"),  with  signatures guaranteed, the
            holder of such Series B Preferred Shares shall be entitled, subject
            to  the  limitations  herein  contained,  to  receive  in  exchange
            therefor  a  certificate  or  certificates  for  fully   paid   and
            nonassessable  shares, which certificates shall be delivered by the
            second trading day  after  the  date  of delivery of the Conversion
            Notice, and cash for fractional shares,  of  Common  Stock  on  the
            foregoing  basis.  The Series B Preferred Shares shall be deemed to
            have been converted,  and  the  person  converting the same to have
            become the holder of record of Common Stock, for all purposes as of
            the date of delivery of the Conversion Notice.

                        (f)   The Company shall, so long as any of the Series B
            Preferred Shares are outstanding, reserve and keep available out of
            its authorized and unissued Common Stock, solely for the purpose of
            effecting  the conversion of the Series B  Preferred  Shares,  such
            number of shares  of  Common  Stock  as  shall from time to time be
            sufficient  to  effect  the  conversion  of all  of  the  Series  B
            Preferred Shares then outstanding.

                        (g)   The Company shall pay any and all taxes which may
            be  imposed upon it with respect to the issuance  and  delivery  of
            Common  Stock  upon the conversion of the Series B Preferred Shares
            as herein provided.  The Company shall not be required in any event
            to pay any transfer  or  other  taxes  by reason of the issuance of
            such Common Stock in names other than those  in  which the Series B
            Preferred Shares surrendered for conversion are registered  on  the
            Company's  records,  and  no  such conversion or issuance of Common
            Stock shall be made unless and  until  the  person  requesting such
            issuance has paid to the Company the amount of any such tax, or has
            established  to  the  satisfaction of the Company and its  transfer
            agent, if any, that such tax has been paid.

                  (3)   VOTING RIGHTS.   Holders  of  Series B Preferred Shares
            shall  have  no voting rights, except as required  by  law  and  by
            Section 7 hereof.

                  (4)   REDEMPTION.    The   Company  may,  but  shall  not  be
            obligated to, at any time subsequent  to ninety (90) days after the
            issuance of the Series B Preferred Shares,  redeem the whole or any
            part  of  the  Series  B  Preferred  Shares then outstanding  at  a
            redemption price of $127 per Preferred  Share,  in  accordance with
            the following redemption procedures:

                        (a)   In case of redemption of only part  of the Series
            B  Preferred  Shares  at  any  time outstanding, the Company  shall
            designate the amount of Series B Preferred Shares so to be redeemed
            and  shall redeem such Series B Preferred  Shares  on  a  PRO  RATA
            basis.  Subject to the limitations and provisions herein contained,
            the Board  of  Directors  shall  have  the  power  and authority to
            prescribe  the  terms  and  conditions  upon  which  the  Series  B
            Preferred Shares shall be redeemed from time to time.

                        (b)   Notice of every redemption shall be given by mail
            to every holder of record of any Series B Preferred Shares  then to
            be  redeemed,  at  least thirty (30), but no more than ninety (90),
            days  prior to the date  fixed  as  the  date  for  the  redemption
            thereof,  at  the  respective addresses of such holders as the same
            shall appear on the  stock  transfer  books  of  the  Company.  The
            notice  shall  state  that  the Series B Preferred Shares shall  be
            redeemed by the Company at the  redemption  price  specified above,
            upon  the  surrender  for  cancellation,  at  the  time  and  place
            designated  in  such  notice, of the certificates representing  the
            Series B Preferred Shares  to  be  redeemed,  properly  endorsed in
            blank  for  transfer,  or  accompanied  by  proper  instruments  of
            assignment  and transfer in blank, with signatures guaranteed,  and
            bearing all necessary  transfer  tax  stamps  thereto  affixed  and
            cancelled.  On and after the date specified in the notice described
            above,  each  holder  of  Series  B  Preferred  Shares  called  for
            redemption  shall  be  entitled  to  receive therefor the specified
            redemption  price  upon presentation and  surrender  at  the  place
            designated  in  such  notice  of  the  certificates  for  Series  B
            Preferred Shares called  for redemption, properly endorsed in blank
            for transfer or accompanied  by proper instruments of assignment or
            transfer  in blank, with signatures  guaranteed,  and  bearing  all
            necessary transfer tax stamps thereto affixed and cancelled.

                        (c)   If the Company shall give notice of redemption as
            aforesaid (and  unless the Company shall fail to pay the redemption
            price of the Series  B Preferred Shares presented for redemption in
            accordance with such notice),  all Series B Preferred Shares called
            for redemption shall be deemed to  have  been  redeemed on the date
            specified in such notice, whether or not the certificates  for such
            Series B Preferred Shares shall be surrendered for redemption,  and
            such  Series B Preferred Shares so called for redemption shall from
            and after  such  date cease to represent any interest whatsoever in
            the Company or its  property, and the holders thereof shall have no
            rights  other than the  right  to  receive  such  redemption  price
            without any interest thereof from and after such date.

                  (5)   LIQUIDATION,  DISSOLUTION, WINDING UP.  In the event of
            any voluntary or involuntary liquidation, dissolution or winding up
            of the Company, the holders  of the Series B Preferred Shares shall
            be entitled to receive in cash  out  of  the assets of the Company,
            whether from capital or from earnings, available  for  distribution
            to  its  stockholders  (the  "PREFERRED FUNDS"), before any  amount
            shall be paid to the holders of  the  Common Stock, an amount equal
            to the Stated Value per Series B Preferred Share, provided that, if
            the Preferred Funds are insufficient to  pay the full amount due to
            the holders of Series B Preferred Shares and  holders  of shares of
            other classes or series of preferred stock of the Company  that are
            of equal rank with the Series B Preferred Shares as to payments  of
            Preferred  Funds  (the  "PARI  PASSU  SHARES"), then each holder of
            Series B Preferred Shares and Pari Passu  Shares  shall  receive  a
            percentage  of  the  Preferred  Funds  equal  to the full amount of
            Preferred Funds payable to such holder as a percentage  of the full
            amount  of  Preferred  Funds  payable  to  all holders of Series  B
            Preferred  Shares  and  Pari  Passu  Shares.    The   purchase   or
            redemption  by  the  Company  of  stock of any class, in any manner
            permitted by law, shall not, for the  purposes  hereof, be regarded
            as  a  liquidation,  dissolution  or  winding  up  of the  Company.
            Neither the consolidation nor merger of the Company  with  or  into
            any other corporation or corporations, nor the sale or transfer  by
            the  Company  of  less than substantially all of its assets, shall,
            for the purposes hereof, be deemed to be a liquidation, dissolution
            or winding up of the  Company.   No  holder  of  Series B Preferred
            Shares  shall  be  entitled  to  receive  any amounts with  respect
            thereto  upon any liquidation, dissolution or  winding  up  of  the
            Company other than the amounts provided for herein.

                  (6)   PREFERRED RANK.  All shares of Common Stock shall be of
            junior rank  to  all  Series  B  Preferred Shares in respect to the
            preferences as to distributions and  payments upon the liquidation,
            dissolution or winding up of the Company.  The rights of the shares
            of Common Stock shall be subject to the  preferences  and  relative
            rights  of  the  Series B Preferred Shares.  The Series B Preferred
            Shares  shall  be  of  equal  rank  with  the  Company's  Series  A
            Cumulative Convertible  Preferred Stock in respect of distributions
            and payments upon the liquidation, dissolution or winding up of the
            Company.  Notwithstanding  the foregoing, the Company may authorize
            and issue additional or other  preferred stock which is of equal or
            junior rank with the Series B Preferred  Shares  in  respect of the
            preferences as to distributions and payments upon the  liquidation,
            dissolution  or winding up of the Company; PROVIDED, HOWEVER,  that
            for so long as the Series B Preferred Shares remain outstanding the
            Company shall  not  issue any capital stock which is more senior in
            rank than the Series B Preferred Shares in respect of the foregoing
            preferences. In the event  of  the  merger  or consolidation of the
            Company with or into another corporation, the  Series  B  Preferred
            Shares  shall  maintain  their  relative  powers,  designations and
            preferences provided for herein.

                  (7)   VOTE TO CHANGE THE TERMS OF SERIES B PREFERRED  SHARES.
            The  affirmative vote at a meeting duly called for such purpose  or
            the written  consent  without  a meeting of the holders of not less
            than two-thirds (2/3) of the then  outstanding  Series  B Preferred
            Shares shall be required to amend, alter, change or repeal  any  of
            the  powers,  designations,  preferences and rights of the Series B
            Preferred Shares.


      IN WITNESS WHEREOF, the Company has  caused this certificate to be signed
by Peter G. Tombros, its President, and John  A.  Caruso,  its  Secretary, this
31st day of January 1996.

                           STOCK PURCHASE AGREEMENT


            AGREEMENT dated as of June 30, 1995 by and between ENZON,  INC.,  a
Delaware  corporation,  with  offices  at  20 Kingsbridge Road, Piscataway, New

                             W I T N E S S E T H:

            WHEREAS, Purchaser  desires  hereby to make an equity investment in
Seller on the terms and conditions hereinafter set forth; and

            WHEREAS, Seller desires Purchaser to make such an investment.

            NOW,  THEREFORE,  in consideration  of  the  mutual  covenants  and
conditions contained herein, the parties hereto agree as follows:

SECTION 1.  PURCHASE AND SALE OF THE SHARES.

            1.1   PURCHASE AND  SALE.   Subject  to  and  upon  the  terms  and
conditions of this Agreement, Seller agrees to sell to Purchaser, and Purchaser
agrees to purchase from Seller, on the Closing Date (as defined in Section 8.1)
hereof,  that  number  of  shares (the "Shares") of the Seller's $.01 par value
common stock (the "Common Stock")  equal  to  the  quotient  of (i) $2,000,000,
divided by (ii) the Per Share Purchase Price (as defined in Section 1.2).

            1.2   PURCHASE PRICE.  The per share purchase price (the "Per Share
Purchase Price") for the Shares shall be the average of the last  reported sale
price  of  the  Common  Stock during the period commencing on May 18, 1995  and
ending on June 28, 1995,  as reported by the National Association of Securities
Dealers Automated Quotation  National  Market  System  ("NASDAQ") (adjusted for
stock  splits,  recapitalizations or similar events).  The  aggregate  purchase
price for the Shares shall be $2,000,000 (the "Purchase Price").

            1.3   PAYMENT  AT  CLOSING  AND DELIVERY OF SHARES.  On the Closing
Date,  Purchaser  shall pay to Seller the Purchase  Price  for  the  Shares  in
immediately available  funds by either bank or cashier's check or wire transfer
to an account designated by the Seller.  Simultaneously therewith, Seller shall
deliver to Purchaser certificates representing the Shares.

SECTION 2.  REPRESENTATIONS AND WARRANTIES OF SELLER.

            Seller hereby represents and warrants to Purchaser as follows:

            2.1   ORGANIZATION  AND  QUALIFICATION.  Each of the Seller and its
subsidiaries is a corporation duly organized  and  existing  in  good  standing
under the laws of the jurisdiction in which it is incorporated, except,  in the
case  of  such  subsidiaries,  as  would not have a Material Adverse Effect (as
defined below), and has the requisite corporate power to own its properties and
to carry on its business as now being  conducted.   Each  of the Seller and its
subsidiaries is duly qualified as a foreign corporation to  do  business and is
in  good  standing  in  every jurisdiction in which the nature of the  business
conducted or property owned  by it makes such qualification necessary and where
the failure so to qualify would  have  a  Material  Adverse  Effect.  "Material
Adverse Effect" means any material adverse effect on the operations, properties
or financial condition of the Seller and its subsidiaries taken as a whole.
            2.2  AUTHORIZATION; ENFORCEMENT.  (i) The Seller has  the requisite
corporate power and authority to enter into and perform this Agreement  and  to
issue  the  Shares  in accordance with the terms hereof, (ii) the execution and
delivery of this Agreement  by  the  Seller  and  the consummation by it of the
transactions  contemplated  hereby have been duly authorized  by  the  Seller's
Board of Directors and no further consent or authorization of the Seller or its
Board of Directors or stockholders  is  required, (iii) this Agreement has been
duly executed and delivered by the Seller,  and (iv) this Agreement constitutes
a valid and binding obligation of the Seller  enforceable against the Seller in
accordance  with its terms, except as such enforceability  may  be  limited  by
applicable bankruptcy,  insolvency,  reorganization, moratorium, liquidation or
similar laws relating to, or affecting  generally the enforcement of creditors'
rights and remedies or by other equitable principles of general application.

            2.3  CAPITALIZATION.  As of March  31, 1995, the authorized capital
stock of the Seller consisted of (i) 40,000,000 shares of Common Stock of which
25,481,385  shares were issued and outstanding and  (ii)  3,000,000  shares  of
Preferred Stock  $.01 par value, of which 109,000 shares designated as Series A
Cumulative Convertible Preferred Stock (the "Preferred Stock"), were issued and
outstanding.  All  of  such outstanding shares have been validly issued and are
fully paid and nonassessable.  No shares of Common Stock or Preferred Stock are
entitled to preemptive rights.   Except  as  disclosed  in  SCHEDULE 2.3, as of
March  31, 1995, there are no outstanding options, warrants, scrip,  rights  to
subscribe  to, calls or commitments of any character whatsoever relating to, or
securities or  rights  convertible  into,  any  shares  of capital stock of the
Seller or any of its subsidiaries, or arrangements by which  the  Seller or any
of  its  subsidiaries  is  or  may  become bound to issue additional shares  of
capital stock of the Seller or any of  its  subsidiaries  or options, warrants,
scrip,  rights  to  subscribe  to, or commitments to purchase or  acquire,  any
shares, or securities or rights  convertible  into  shares, of capital stock of
the  Seller  or  any  of  its subsidiaries.  The Seller has  furnished  to  the
Purchaser true and correct  copies of the Seller's Certificate of Incorporation
as  in  effect on the date hereof  ("Certificate  of  Incorporation")  and  the
Seller's By-laws as in effect on the date hereof (the "By-laws").

            2.4   ISSUANCE  OF SHARES.  The Shares are duly authorized and when
paid for in accordance with the  terms  hereof  shall  be validly issued, fully
paid and non-assessable and, based in part on the representations  of Purchaser
contained in Sections 3 and 4 of this Agreement, will be issued to Purchaser in
compliance with all  applicable Federal and State securities laws.

            2.5   NO  CONFLICTS.   The  execution, delivery and performance  of
this  Agreement  by  the  Seller and the consummation  by  the  Seller  of  the
transactions contemplated thereby  do  not  (i)  result  in  a violation of the
Seller's  Certificate  of Incorporation or By-laws, or (ii) conflict  with,  or
constitute a default (or  an  event  which with notice or lapse of time or both
would become a default) under, or give  to  others  any  rights of termination,
amendment,  acceleration  or  cancellation  of,  any  agreement,  indenture  or
instrument to which the Seller or any of its subsidiaries is a party, or to the
best knowledge of Seller, result in a violation of any  law,  rule, regulation,
order,  judgment  or  decree (including Federal and state securities  laws  and
regulations) applicable  to the Seller, any of its subsidiaries or by which any
property or asset of the Seller or any of its subsidiaries is bound or affected
(except for such conflicts,  defaults, terminations, amendments, accelerations,
cancellations and violations as  would  not,  individually or in the aggregate,
have  a  Material  Adverse  Effect).  To the best of  Seller's  knowledge,  the
businesses of the Seller and  its  subsidiaries  are  not  being  conducted, in
violation  of  any  law,  ordinance  or  regulation of any governmental entity,
except for possible violations which either  singly  or in the aggregate do not
have a Material Adverse Effect.  Except as required under the Securities Act of
1933,  as  amended (the "Securities Act") and any applicable  state  securities
laws, the Seller  is not required to obtain any consent, authorization or order
of, or make any filing  or  registration with, any court or governmental agency
in order for it to execute, deliver  or  perform  any  of its obligations under
this Agreement or issue the Shares, and sell the Shares  in accordance with the
terms hereof.

            2.6   SEC DOCUMENTS, FINANCIAL STATEMENTS.  The  Seller  has  filed
all  reports,  schedules,  forms, statements and other documents required to be
filed by it with the Securities and Exchange Commission (the "SEC") pursuant to
the  reporting  requirements of  the  Securities  Exchange  Act  of  1934  (the
"Exchange Act"), except that the Company inadvertently did not file a Financial
Data Schedule to  its Quarterly Report on Form 10-Q for the quarter ended March
31,  1995 which it intends  to  file  as  soon  as  reasonably  practicable  by
amendment  to  such  Form  10-Q  (all  of the foregoing filed during the period
commencing on January 1, 1993 and ending as of the date hereof and all exhibits
included therein and financial statements  and  schedules thereto and documents
(other  than  exhibits)  incorporated by reference therein,  being  hereinafter
referred to herein as the  "SEC  Documents").   The Seller has delivered to the
Purchaser  true  and  complete  copies of the SEC Documents,  except  for  such
exhibits, schedules and incorporated  documents.  As of their respective dates,
the SEC Documents complied in all material  respects  with  the requirements of
the  Exchange  Act  and  the  rules  and  regulations  of  the  SEC promulgated
thereunder applicable to such SEC Documents, and none of the SEC  Documents, at
the  time  they  were filed with the SEC, contained any untrue statement  of  a
material fact or omitted to state a material fact required to be stated therein
or  necessary in order  to  make  the  statements  therein,  in  light  of  the
circumstances  under  which  they  were  made,  not  misleading.   As  of their
respective  dates,  the financial statements of the Seller included in the  SEC
Documents  complied as  to  form  in  all  material  respects  with  applicable
accounting requirements and the published rules and regulations of the SEC with
respect thereto.   Such  financial  statements have been prepared in accordance
with generally accepted accounting principles  applied  on  a  consistent basis
during the periods involved (except (i) as may be otherwise indicated  in  such
financial  statements  or  the  notes  thereto or (ii) in the case of unaudited
interim statements, to the extent they may  not  include  footnotes  or  may be
condensed  or  summary  statements) and fairly present in all material respects
the  consolidated  financial  position  of  the  Seller  and  its  consolidated
subsidiaries as of the  dates  thereof  and  the  consolidated results of their
operations and cash flows for the periods then ended  (subject,  in the case of
unaudited statements, to normal year-end audit adjustments).

            2.7   ABSENCE  OF UNDISCLOSED LIABILITIES.  Except as disclosed  in
SCHEDULE 2.7, the Seller and  its  subsidiaries  do  not  have any "Undisclosed
Liabilities."  For purposes hereof, "Undisclosed Liabilities"  shall  mean  any
and  all  liabilities  or obligations (whether absolute, accrued, contingent or
otherwise), which are neither  (i)  accrued or reserved against in the Seller's
financial statements contained in the  SEC  Documents or reflected in the notes
thereto, (ii) reflected or disclosed in any other  Schedule furnished under and
referred to in this Agreement, or (iii) normally recurring liabilities incurred
subsequent to March 31, 1995 in the ordinary course  of business and consistent
with past practice.

            2.8   ABSENCE OF ADVERSE CHANGES.  Except  as set forth in SCHEDULE
2.8, since March 31, 1995 through the date hereof, there  has  not been any (i)
material  adverse  change  in  the  business,  operations, properties,  assets,
liabilities  or  condition  (financial  or otherwise)  of  the  Seller  or  its
subsidiaries; (ii) damage, destruction or loss, whether covered by insurance or
not, adversely affecting in any material  respect  the  business, properties or
financial  condition  of the Seller or its subsidiaries; (iii)  change  by  the
Seller  or its subsidiaries  in  accounting  methods  or  principles  used  for
financial  reporting  purposes;  or  (iv)  agreement,  whether  in  writing  or
otherwise,  to  take  any action which would result in a condition described in
this Section 2.8.

            2.9   LITIGATION.  There is no judicial or administrative action or
other proceeding pending  or,  to  the  best  of  the  knowledge of the Seller,
threatened,  nor,  to  the best of the knowledge of the Seller,  is  there  any
governmental investigation  pending  or threatened, that questions the validity
of any of the transactions contemplated by this Agreement.

SECTION 3.  REPRESENTATIONS AND WARRANTIES OF PURCHASER.

            Purchaser hereby represents and warrants to Seller as follows:

            3.1   AUTHORIZATION;  ENFORCEMENT.   (i)   The  Purchaser  has  the
requisite  corporate  power  and authority  to  enter  into  and  perform  this
Agreement, (ii) the execution  and  delivery of this Agreement by the Purchaser
and the consummation by it of the transactions  contemplated  thereby have been
duly  authorized by all necessary corporate action, and no further  consent  or
authorization  of  the  Purchaser  or its Board of Directors or stockholders is
required, (iii) this Agreement has been duly authorized, executed and delivered
by  the Purchaser, and (iv) this Agreement  constitutes  a  valid  and  binding
obligation  of  the  Purchaser  enforceable against the Purchaser in accordance
with  its  terms,  except  as  enforceability  may  be  limited  by  applicable
bankruptcy, insolvency, reorganization, moratorium, liquidation or similar laws
relating to, or affecting generally  the  enforcement of, creditors' rights and
remedies or by other equitable principles of general application.

            3.2   NO CONFLICTS.  The execution,  delivery  and  performance  of
this  Agreement  and  the  consummation  by  the  Purchaser of the transactions
contemplated hereby do not (i) result in a violation of the Purchaser's charter
documents  or by-laws or (ii) conflict with, or constitute  a  default  (or  an
event of default)  under,  any  agreement, indenture or instrument to which the
Purchaser or any of its subsidiaries  is  a  party, or result in a violation of
any  law,  rule,  regulation,  order,  judgment  or  decree  of  any  court  or
governmental   agency  (including  Federal  and  state  securities   laws   and
regulations) applicable  to  the  Purchaser,  any  of its subsidiaries or their
respective properties (except for such conflicts, defaults  and  violations  as
would  not, individually or in the aggregate, have a material adverse effect on
the  Purchaser).   The  Purchaser  is  not  required  to  obtain  any  consent,
authorization  or  order of, or make any filing or registration with, any court
or governmental agency  in  order  for it to execute, deliver or perform any of
its obligations under this Agreement  or purchase the Shares in accordance with
the terms hereof.

            3.3   INVESTMENT INTENT.  Purchaser  is  purchasing  the Shares for
investment  only  for  its  own  account,  and  not with a view to the sale  or
distribution of all or any part thereof, and Purchaser has no present intention
of selling or distributing any of the Shares.  Purchaser understands and agrees
that the Shares are not and will not be registered  under the Securities Act in
reliance on the fact that the sale of the Shares provided for in this Agreement
and the issuance of such securities are exempt from the registration provisions
of the Securities Act and that Seller's reliance on any  exemptions  from  such
registration   provisions   is   predicated,   in   part,  on  the  Purchaser's
representations set forth herein.

            3.4   DISCLOSURE  OF  INFORMATION; ETC.  The  Purchaser  represents
that it has received all the information it considers necessary or appropriate,
including the SEC Documents, to make  its decision to purchase the Shares.  The
Purchaser further represents that it has  had  an  opportunity to ask questions
and receive answers from the Seller regarding the terms  and  conditions of the
purchase of the Shares.

            3.5   STOCK   OWNERSHIP.    Prior   to  the  consummation  of   the
transactions  contemplated  by this Agreement, Purchaser  will  have  owned  no
shares of Common Stock, warrants or other securities of Seller.

SECTION 4.  SECURITIES ACT RESTRICTIONS.

            4.1   NO REGISTRATION  UNDER  THE  SECURITIES  ACT  OF  1933.   The
Purchaser represents  and  warrants  to  the Seller that the Purchaser will not
dispose of any Shares (or any other securities issued with respect thereto upon
any conversion, stock split, stock dividend, recapitalization or similar event)
(collectively the "Restricted Securities")  except pursuant to (i) an effective
registration statement filed under the Securities  Act, (ii) Rule 144 under the
Securities Act (or any similar rule under the Securities  Act  relating  to the
disposition   of  securities)  or  (iii)  an  opinion  of  counsel,  reasonably
satisfactory to counsel for Seller, that an exemption from such registration is
available.

            4.2   CERTIFICATES  TO  BEAR  LEGENDS.   The  Restricted Securities
shall be subject to a stop-transfer order and the certificate  or  certificates
evidencing the Restricted Securities shall bear the following legend:

    "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED  UNDER
THE  SECURITIES  ACT  OF  1933,  AS AMENDED (THE "SECURITIES ACT") OR ANY STATE
SECURITIES LAWS AND MAY NOT BE OFFERED  OR  SOLD  EXCEPT  PURSUANT  TO  (i)  AN
EFFECTIVE  REGISTRATION  STATEMENT  UNDER  THE  SECURITIES  ACT, OR (ii) TO THE
EXTENT APPLICABLE, UNDER RULE 144 UNDER THE SECURITIES ACT (OR ANY SIMILAR RULE
UNDER THE SECURITIES ACT RELATING TO THE DISPOSITION OF SECURITIES),  OR  (iii)
AN  OPINION  OF  COUNSEL,  IF  SUCH OPINION SHALL BE REASONABLY SATISFACTORY TO
COUNSEL FOR THIS CORPORATION, THAT  AN  EXEMPTION  FROM  REGISTRATION UNDER THE
SECURITIES ACT IS AVAILABLE.

            4.3   REMOVAL  OF  LEGENDS AND TRANSFER RESTRICTIONS.   The  legend
relating to the Securities Act endorsed  on  each  certificate  for  Restricted
Securities  pursuant  to  Section  4.2 and any stop transfer instructions  with
respect to the Restricted Securities  represented  by such certificate shall be
removed and Seller shall issue a certificate without  such  legend  pursuant to
instructions received from the Purchaser if such Restricted Securities are sold
pursuant  to  a registration under the Securities Act and a prospectus  meeting
the requirements  of  Section  10 of the Securities Act is available, or if the
Purchaser provides to Seller an opinion of counsel for the Purchaser reasonably
satisfactory to Seller, or a no-action  letter  or  interpretive opinion of the
staff of the SEC to the effect that a public sale, transfer  or  assignment  of
such   Restricted  Securities  may  be  made  without  registration  under  the
Securities Act.

            4.4   TRANSFER  TO  AFFILIATES.   Notwithstanding the provisions of
Section  4.1  above, no registration under the Securities  Act  or  opinion  of
counsel shall be  necessary  for  a  transfer  by  Purchaser of the Shares to a
subsidiary, shareholder or affiliate of the Purchaser, if the transferee agrees
in writing to be subject to the terms hereof to the  same  extent  as  if  such
transferee were the Purchaser hereunder.

defined in this Section 7 shall  have  the  meanings  herein  specified for all
purposes of this Agreement, applicable to both the singular and plural forms of
any of the terms herein defined.

                  "BOARD" means the Board of Directors of the Company.

                  "HOLDER" of any security means the record or beneficial owner
of such security or any permitted assignee thereof.

                  "PERSON"  means  any  natural  person,  corporation,   trust,
association,  company,  partnership,  joint  venture  or  other  entity  or any
government, governmental agency, instrumentality or political subdivision.

                  The terms "REGISTER", "REGISTERED" "REGISTRATION" refer  to a
registration  effected  by  preparing  and  filing  a registration statement in
compliance with the Securities Act, and the declaration  for  ordering  of  the
effectiveness of such registration statement.

                  "REGISTRABLE SECURITIES" means (i) the shares of Common Stock
sold  pursuant  to  this Agreement and (ii) any Common Stock issued or issuable
(either directly or upon the conversion of or exercise of any warrant, right or
other security) with  respect  to  the  Common  Stock referred to in clause (i)
above  by  way  of  a stock dividend or stock split or  in  connection  with  a
combination   of  shares,   reclassification,   recapitalization,   merger   or

securities transaction, or (x) sold in a transaction pursuant to Rule 144 under
the  Securities  Act,  or  (y)  otherwise  transferred  or disposed of, and new
certificates therefor not bearing a legend restricting further  transfer  shall
have  been delivered by the Company, and subsequent transfer or disposition  of
them shall not require their registration or qualification under the Securities
Act or  any  similar  state  law  then  in  force,  or  (z)  they  cease  to be
outstanding.

            7.2 DEMAND REGISTRATION.

                  (a)   If  and  whenever the Company shall receive at any time
after  six  (6)  months after the Closing  Date  hereunder  a  written  request
therefor from the Holders of at least 25 percent of the Registrable Securities,
the Company agrees  to prepare and file promptly a registration statement under
the Securities Act covering  the shares of Registrable Securities which are the
subject of such request and agrees  to  use  its  best  efforts  to  cause such
registration statement to become effective as expeditiously as possible.   Upon
the  receipt  of such request, the Company agrees to give prompt written notice
to all Holders  of  Registrable  Securities  that  such  registration  is to be
effected.   The  Company agrees to include in such registration statement  such
shares of Registrable Securities for which it has received a written request to
register such shares  by  the Holders thereof within twenty (20) days after the
receipt by the Holders of the written notice from the Company.

                  (b)  The  Company  shall  be  obligated  to prepare, file and
cause  to become effective only three (3) registration statements  pursuant  to
this Section  7.2.   A  registration  required  to  be  effected by the Company
pursuant  to this Section 7.2 shall not be deemed to have  been  effected  even
though a registration  statement  with respect thereto has become effective (i)
if after it has become effective, such  registration becomes the subject of any
stop order, injunction, or other order or  requirement  of  the  SEC  or  other
governmental  agency  or  court, for any reason not attributable to the Holders
initiating the registration  request  hereunder (the "Initiating Holders") with
respect to such registration statement, and has not thereafter become effective
or (ii) if the conditions to closing specified  in  the underwriting agreement,
if any, entered into in connection with such registration  are not satisfied or
waived, other than by reason of a failure on the part of the Initiating Holders
with respect to such registration statement.

                  (c)   If  the  Initiating  Holders  intend to distribute  the
Registrable Securities covered by their request by means  of  an  underwriting,
they agree to provide the Company with the name of the managing underwriter  or
underwriters  (the  "Managing Underwriter"), who shall be reasonably acceptable
to the Company, that the Initiating Holders holding a majority of the Shares to
be included in the registration  propose  to  employ,  as part of their request
made  pursuant  to  this Section 7.2, and the Company agrees  to  include  such
information in its written  notice  referred  to  in  Section 7.2.(a).  In such
event, the right of any Holder to registration pursuant  to  this  Section  7.2
shall  be conditioned upon such Holder's participation in such underwriting and
the inclusion  of  such  Holder's  Registrable  Securities  in the underwriting
(unless otherwise mutually agreed by the Holders of a majority of the shares of
Registrable  Securities to be included in such registration and  such  Holder).
All Holders proposing  to distribute their securities through such underwriting
agree to enter into (together  with the Company) an underwriting agreement with
the underwriter or underwriters  elected  for  such underwriting, in the manner
set forth above, provided that such underwriting agreement is in customary form
and is reasonably acceptable to the Holders of a  majority  of  the  shares  of
Registrable Securities to be included in such registration.

                  (d)    Notwithstanding   the   foregoing,   if  the  Managing
Underwriter of an underwritten distribution advises the Company and the Holders
of Registrable Securities participating in such registration in writing that in
its good faith judgment the number of shares of Registrable Securities  and the
other  securities  requested  to  be  included in such registration exceeds the
number of shares of Registrable Securities  and  the other securities which can
be  sold in such offering, then (i) the other securities  so  requested  to  be
included  in  such  registration  shall  initially be reduced and the number of
shares  of  Registrable  Securities  so  requested   to  be  included  in  such
registration shall subsequently be reduced, together to  that  number of shares
which  in the good faith judgment of the Managing Underwriter can  be  sold  in
such offering  and  (ii)  the  reduced  number  of Registrable Securities to be
included in the underwriting shall be allocated pro  rata  among all Holders of
Registrable Securities.  Those Registrable Securities which  are  excluded from
the  underwriting by reason of the Managing Underwriter's marketing  limitation
shall  not  be  included  in  such  registration and shall be withheld from the
market  by  the Holders thereof for a period  which  the  Managing  Underwriter
reasonably determines  is necessary to effect the underwritten public offering,
which in no event shall be in excess of 120 days.

            7.3 "PIGGYBACK" REGISTRATION.

                  (a)   Each  time  the  Company  shall  determine  to  file  a
registration statement under the Securities Act (other than pursuant to Section
7.2 hereof and other than  on Form S-4, S-8 or a registration statement on Form
S-1 covering solely any employee  benefit plan) in connection with the proposed
offer and sale for money of any of its securities either for its own account or
on behalf of any other security holder,  the  Company  agrees  to  give  prompt
written  notice  of its determination to all Holders of Registrable Securities.
Upon the written request  of  a  Holder of any shares of Registrable Securities
given within twenty (20) days after the receipt of such written notice from the
Company,  the Company agrees to cause  all  such  Registrable  Securities,  the
Holders of which have so requested registration thereof, to be included in such
registration  statement  and to use its best efforts to cause such registration
statement to become effective  under the Securities Act.  In the event that the
proposed registration by the Company  is,  in whole or in part, an underwritten
public offering of securities of the Company,  any  request  pursuant  to  this
Section  7.3(a)  to  register  Registrable  Securities  may  specify  that such
securities  are  to  be included in the underwriting (i) on the same terms  and
conditions as the shares  of Common Stock, if any, otherwise being sold through
underwriters,  under  such  registration,  or  (ii)  on  terms  and  conditions
comparable  to those normally  applicable  to  offerings  of  Common  Stock  in
reasonably similar  circumstances  in  the event that no shares of Common Stock
other than Registrable Securities are being  sold  through underwriters in such
registration.

                  (b)  If the registration of which  the  Company gives written
notice pursuant to Section 7.3(a) is for an underwritten public  offering,  the
Company  agrees  to  so advise the Holders as a part of its written notice.  In
such event the right of any Holder to registration pursuant to this Section 7.3
shall be conditioned upon  such Holder's participation in such underwriting and
the inclusion of such Holder's  Registrable  Securities  in the underwriting to
the  extent  provided  herein.   All  Holders  proposing  to  distribute  their
Registrable Securities through such underwriting agree to enter  into (together
with  the  Company and the other Holders distributing their securities  through
such  underwriting)    an   underwriting  agreement  with  the  underwriter  or
underwriters selected for such underwriting by the Company.

                  (c)  Notwithstanding any other provision of this Section 7.3,
if the Managing Underwriter of an underwritten distribution advises the Company
and the Holders of the Registrable  Securities requesting participation in such
registration in writing that in its good faith judgment the number of shares of
Registrable Securities and the other  securities  requested  to  be  registered
under  this  Section 7.3 exceeds the number of shares of Registrable Securities
and other securities which can be sold in such offering, then (i) the number of
shares of Registrable  Securities  and  other  securities  so  requested  to be
included in the offering shall be reduced to that number of shares which in the
good  faith  judgment  of the Managing Underwriter can be sold in such offering
(except for shares to be  issued  by  the  Company  in a public offering, which
shall have priority over the Registrable Securities),  and  (ii)  such  reduced
number  of  shares  shall  be  allocated  among  all  participating  Holders of
Registrable Securities and holders of other securities in proportion, as nearly
as  practicable,  to  the respective number of shares of Registrable Securities
and other securities requested  to  be  registered  held by such Holders at the
time  of  filing  the registration statement.  All Registrable  Securities  and
other securities which  are  excluded  from  the  underwriting by reason of the
Managing   Underwriter's  marketing  limitation  and  all   other   Registrable
Securities not  originally requested to be so included shall not be included in
such registration  and shall be withheld from the market by the Holders thereof
for a period which the  Managing Underwriter reasonably determines is necessary
to effect the underwritten  public offering, which in no event shall exceed 120
days.

                7.4     REGISTRATION EXPENSES.

                  (a)  The Company shall pay all expenses incurred in effecting
the registration of Registrable  Securities  pursuant  to  Section 7 including,
without  limitation,  all  federal  and  state registration, qualification  and
filing  fees  (subject  to  Section  7.5(d)),  printing   expenses,   fees  and
disbursements of counsel for the Company, reasonable fees and disbursements  of
one counsel for the participating Holders together, blue sky fees and expenses,
and  the  expense  of  any  special  audits incident to or required by any such
registration,  but  not  including  underwriting   discounts,  commissions  and
expenses.

                  (b)   Notwithstanding the foregoing,  in  the  event  that  a
registration pursuant to Section 7.2 is requested by the Initiating Holders and
such request is withdrawn  prior  to  the filing of a registration statement by
the  Company, or such Holder causes the  Company  to  withdraw  a  registration
statement  prior  to  its  effectiveness,  then at the choice of the Initiating
Holders and Holders requesting inclusion of  their  shares in such registration
statement either (i) the Initiating Holders and Holders requesting inclusion of
their shares in such registration shall bear pro rata  all  expenses  otherwise
borne  by  the  Company  and set forth in Section 7.4(a) or (ii) such requested
registration shall be deemed  to  be  one  of  the registrations the Company is
required to effect pursuant to Section 7.2 hereof;  provided however, if at the
time  of  the  withdrawal, the Initiating Holders and the  other  Holders  have
learned of a material adverse change which would have a Material Adverse Effect
with respect to  the Company which was not known to such Holders at the time of
their request, then  such  Holders  shall  not  be  required to pay any of such
registration expenses and shall retain their rights pursuant to Section 7.2.

            7.5 REGISTRATION  PROCEDURES.   If  and  whenever  the  Company  is
required  by  the  provisions  of  Section  7  to  effect the  registration  of
Registrable  Securities  under  the  Securities  Act,  the   Company  will,  as
expeditiously as possible:

                  (a)   prepare and file with the SEC a registration  statement
which includes the Registrable  Securities  and  use  its best efforts to cause
such  registration  statement  to  become  and  remain  effective   until   the
distribution described in the registration statement has been completed;
                  (b)   prepare  and  file  with  the  SEC  such amendments and
supplements  to  such  registration  statement  and  the  prospectus   used  in
connection  therewith  as  may be necessary to keep such registration statement
effective and to comply with  the provisions of the Securities Act with respect
to the sale or other disposition  of  Registrable  Securities  covered  by such
registration  statement  whenever  a  Holder  shall desire to sell or otherwise
dispose of the same;

                  (c)   furnish  to  each participating  Holder  (and  to  each
underwriter, if any, of Registrable Securities)  such  number  of  copies  of a
prospectus,   including  a  preliminary  prospectus,  in  conformity  with  the
requirements of  the  Securities Act, in order to facilitate the public sale or
other disposition of the Registrable Securities;

                  (d)   use  its  best  efforts  to  register  or  qualify  the
Registrable  Securities covered by such registration statement under such state
securities or  blue  sky laws of such jurisdiction as each participating Holder
shall reasonably request  and do any and all other acts and things which may be
necessary under such securities  or  blue  sky  laws  to  enable such Holder to
consummate  the public sale or other disposition of the Registrable  Securities
in such jurisdictions,  except  that  the  Company shall not for any purpose be
required to consent generally to service of  process  or qualify to do business
as a foreign corporation in any jurisdiction wherein it is not so qualified;

                  (e)  before filing the registration statement  or  prospectus
or  amendments  or  supplements  thereto,  furnish  to  counsel selected by the
participating Holders copies of such documents proposed to be filed which shall
be subject to the reasonable approval of such counsel;

                  (f)   enter  into  and  perform  its  obligations   under  an
underwriting  agreement,  in  usual  and  customary  form,  with  the  Managing
Underwriter of such offering;

                  (g)   notify  the  participating  Holders at any time when  a
prospectus relating to any Registrable Securities covered  by such registration
statement  is  required  to  be  delivered  under  the Securities Act,  of  the
happening  of any event as a result of which the prospectus  included  in  such
registration  statement,  as  then in effect, includes an untrue statement of a
material fact or omits to state  a  material fact required to be stated therein
or necessary to make the statements therein  not  misleading  in  light  of the
circumstances  in  which  they  were made and promptly file such amendments and
supplements  as may be necessary so  that,  as  thereafter  delivered  to  such
Holders of such  Registrable  Securities,  such prospectus shall not include an
untrue statement of a material fact or omit  to  state a material fact required
to be stated therein or necessary to make the statements therein not misleading
in light of the circumstances in which they were made  and use its best efforts
to cause each such amendment to become effective;

                  (h)  furnish at the request of the participating  Holders  on
the date that such Registrable Securities are delivered to the underwriters for
sale  in  connection  with  a registration pursuant to Section 7 (i) an opinion
addressed to the underwriters, if any, and to such Holders, dated such date, of
the counsel representing the  Company  customarily  given by company counsel to
the underwriters in an underwritten public offering,  and  (ii)  a letter dated
such date addressed to the underwriters, if any, and to such Holders,  from the
independent  certified public accountants of the Company, in form and substance
as  is  customarily  given  by  independent  certified  public  accountants  to
underwriters in an underwritten public offering; and

                  (i)   use  its  best  efforts  to  cause all such Registrable
Securities to be listed on the securities exchange, if  any,  or  the  National
Association  of  Securities  Dealers Automated Quotation National Market System
("NASDAQ/NMS"), on which the Common Stock is then listed.

            7.6 FORM S-3 REGISTRATION.   In  case  the Company shall receive no
sooner than six (6) months after the Closing Date from  any Holder or Holders a
written request or requests that the Company effect a registration  on Form S-3
and  any related qualification with respect to all or a part of the Registrable
Securities owned by such Holder or Holders, the Company shall:

                  (a)    promptly   give   written   notice   of  the  proposed
registration, and any related qualification, to all other Holders; and

                  (b)   as  soon as practicable, file a registration  statement
and  effect  such registration  and  all  such  qualifications  as  may  be  so
requested, subject  to  Section  7.5(d)  hereof,  and  as  such portion of such
Holder's or Holders' Registrable Securities as are specified  in  such request,
together  with all or such portion of the Registrable Securities of  any  other
Holder or Holders  joining  in  such  request  as  are  specified, in a written
request given within 15 business days after receipt of such written notice from
the  Company,  provided, however, that the Company shall not  be  obligated  to
effect any such  registration  or  qualification  pursuant to this Section 7.6:
(i) if Form S-3 is not available for such offering  by the Holders; (ii) if the
Holders,  together  with  the holders of any other securities  of  the  Company
entitled  to  inclusion  in such  registration,  propose  to  sell  Registrable
Securities and such other  securities  (if  any)  at  an aggregate price to the
public (net of any underwriters' discounts or commissions)  of  less  than Five
Hundred Thousand Dollars ($500,000); (iii) if the Company shall furnish  to the
Holders a certificate signed by the President or Chief Executive Officer of the
Company  stating  that  in  the  good  faith judgment of the Board, it would be
seriously detrimental to the Company for  such  Form  S-3  Registration  to  be
effected at such time, in which event the Company shall have the right to defer
the filing of the Form S-3 Registration Statement for a period of not more than
90  days  after  receipt  of  the  request  of the Holder or Holders under this
Section 7.6; provided, however, that the Company  shall  not utilize this right
more than once in any 12-month period; (iv) if the Company  has, within the 12-
month  period  preceding  the  date  of  such  request,  already  effected  one
registration on Form S-3 for the Holders pursuant to this Section 7.6;  or  (v)
in  any  particular  jurisdiction  in  which  the  Company would be required to
qualify to do business or to execute a general consent to service of process in
effecting such registration, qualification or compliance.

                  (c)   Registrations effected pursuant  to  this  Section  7.6
shall not be counted as demand registrations effected pursuant to Section 7.2.

            7.7 INDEMNIFICATION.   In  the  event  Registrable  Securities  are
registered pursuant to this Section 7:

                  (a)   To  the  extent  permitted  by  law,  the  Company will
indemnify  and  hold  harmless each Holder of Registrable Securities which  are
included  in  a registration  statement  pursuant  to  the  provisions  of  the
Agreement and any  underwriter  (within the meaning of the Securities Act) with
respect to the Registrable Securities, and each officer, director, employee and
agent thereof and each person, if  any,  who  otherwise controls such Holder or
underwriter (within the meaning of the Securities  Act),  against  any  losses,
claims,  damages, expenses or liabilities, joint or several, to which they  may
become subject  under  the Securities Act, the Securities Exchange Act of 1934,
as amended (the "Exchange  Act")  or  other federal or state law, or otherwise,
insofar as such losses, claims, damages,  expenses  or liabilities arise out of
or are based upon any untrue or allegedly untrue statement of any material fact
contained  in  the  registration  statement  for  the  Registrable  Securities,
including any preliminary prospectus or final  prospectus  contained therein or
any  amendments  or  supplements  thereto,  or  any  document incident  to  the
registration or qualification of any Registrable Securities, or arise out of or
are  based upon the omission or alleged omission to state  therein  a  material
fact required  to  be  stated  therein  or  allegedly  necessary  to  make  the
statements  therein  not  misleading  or  arise out of any violation or alleged
violation by the Company of the Securities  Act,  the  Exchange  Act, any state
securities law or any rule or regulation promulgated under the Securities  Act,
the  Exchange  Act or any state securities law; and will reimburse such Holder,
any underwriter,  officer,  director, employee, agent or controlling person for
any legal or other expenses reasonably  incurred  by  them  in  connection with
investigating or defending any such loss, claim, damage, liability  or  action;
provided,  however,  that  the  indemnity  agreement  contained in this Section
7.7(a) shall not apply to amounts paid in settlement of  any  such loss, claim,
damage, expense, liability or action if such settlement is effected without the
written consent of the Company, which shall not be unreasonably  withheld,  nor
shall  the  Company  be  liable  under this Section 7.7(a) to such Holder, such
underwriter, officer, director, employee,  agent  or controlling person for any
such loss, claim, damage, expense, liability or action  to  the  extent that it
arises  out  of,  or  is  based  upon, an untrue statement or allegedly  untrue
statement  or  omission  or  alleged omission  made  in  connection  with  such
registration statement, preliminary prospectus, final prospectus, or amendments
or supplements thereto, in reliance  upon  and  in  conformity with information
furnished in writing expressly for use in connection  with such registration by
such  Holder,  such  underwriter, officer, director, employee,  agent  or  such
controlling person, nor  shall  the Company be liable under this Section 7.7(a)
to any underwriter or person who  controls  any underwriter (within the meaning
of  the  Securities  Act)  who participates in the  offering  or  sale  of  the
Registrable Securities, with  respect  to  any  preliminary  prospectus,  final
prospectus,  or  amendments  or supplements thereto to the extent that any such
loss, claim, damage or liability  results  from  the fact that such underwriter
sold Registrable Securities to a person to whom there was not sent or given, at
or  prior  to  the  written confirmation of such sale,  a  copy  of  the  final
prospectus  or  of the  final  prospectus  as  then  amended  or  supplemented,
whichever is most  recent,  if  the  Company  has  previously  furnished copies
thereof to such underwriter.

                  (b)    To  the  extent  permitted  by  law,  each  Holder  of
Registrable Securities which are included in a registration statement  pursuant
to  the  provisions  of  this  Agreement  will  indemnify and hold harmless the
Company, each of its employees, agents, directors and officers, each person, if
any, who otherwise controls the Company (within the  meaning  of the Securities
Act),  and any underwriter (within the meaning of the Securities  Act)  against
any losses,  claims,  damages,  expenses or liabilities to which the Company or
any such person or underwriter may become subject under the Securities Act, the
Exchange Act or other federal or  state  law  or  otherwise,  insofar  as  such
losses, claims, damages, expenses or liabilities (or action in respect thereof)
arise out of, or are based upon any untrue or allegedly untrue statement of any
material  fact  contained  in  a  registration  statement  for  the Registrable
Securities, including any preliminary prospectus or final prospectus  contained
therein  or any amendments or supplements thereto, or any document incident  to
the registration  or  qualification of any Registrable Securities, or arise out
of or are based upon the  omission  or  alleged  omission  to  state  therein a
material fact required to be stated therein or allegedly necessary to make  the
statements  therein not misleading; in each case to the extent that such untrue
statement or  allegedly  untrue  statement  or omission or alleged omission was
made in such registration statement, preliminary  prospectus,  or amendments or
supplements  thereto,  in  reliance  upon  and  in  conformity with information
furnished in writing by such Holder expressly for use  in  connection with such
registration; provided, however, that the indemnity agreement contained in this
Section 7.7(b) shall not apply to amounts paid in settlement  of any such loss,
claim,  damage,  expense,  liability or action if such settlement  is  effected
without the written consent  of  such  Holder,  which shall not be unreasonably
withheld; and such Holder will reimburse the Company  or  any  such  person  or
underwriter  for any legal or other expenses reasonably incurred by the Company
or any such person or underwriter in connection with investigating or defending
such loss, claim, damage, liability, expense or action.

                  (c)   Promptly  after  receipt  by an indemnified party under
this Section 7.7 of notice of the commencement of any  action, such indemnified
party  will,  if  a  claim  in  respect  thereof  is  to  be made  against  any
indemnifying  party  under this Section 7.7, notify the indemnifying  party  in
writing of the commencement  thereof  and generally summarize such action.  The
indemnifying party shall have the right  to  participate  in  and to assume the
defense  thereof  with  counsel  mutually  satisfactory  to  the  parties.   An
indemnifying  party shall not have the right to direct the defense of  such  an
action on behalf  of  an  indemnified  party  if  such  indemnified  party  has
reasonably  concluded  that  there  may  be  defenses  available to it that are
different  from  or  additional  to those available to the indemnifying  party;
provided, however, that in such event,  the  indemnifying  party shall bear the
fees and expenses of only one (1) separate counsel for all indemnified parties.
The failure to notify an indemnifying party promptly of the commencement of any
such action if prejudicial to the ability to defend such action,  shall relieve
such  indemnifying  party of any liability to the indemnified party under  this
Section 7.7, but the  omission  so  to  notify  the indemnifying party will not
relieve such party of any liability that such party may have to any indemnified
party otherwise than under this Section 7.7.
                  (d)   To  the extent permitted by  law,  the  indemnification
provided for under this Section  7.7  will  remain  in  full  force  and effect
regardless  of  any  investigation  made  by  a  controlling person (within the
meaning of the Securities Act) of such indemnified  party  and will survive the
transfer of any securities.

                  (e)  If for any reason the foregoing indemnity is unavailable
to,  or  is  insufficient  to  hold  harmless  an indemnified party,  then  the
indemnifying  party  shall contribute to the amount  paid  or  payable  by  the
indemnified party as a  result  of  such  losses,  claims, damages, expenses or
liabilities (i) in such proportion as is appropriate  to  reflect  the relative
benefits received by the indemnifying party on the one hand and the indemnified
party  on the other or (ii) if the allocation provided by clause (i)  above  is
not permitted  by  applicable  law, or provides a lesser sum to the indemnified
party than the amount representing such proportion as is appropriate to reflect
not only the relative benefits received  by  the  indemnifying party on the one
hand and the indemnified party on the other but also  the relative fault of the
indemnifying  party  and the indemnified party as well as  any  other  relevant
equitable considerations.   Notwithstanding  the  foregoing, no underwriter, if
any, shall be required to contribute any amount in  excess  of  the  amount  by
which  the  total  price  at  which  the  securities  underwritten  by  it  and
distributed to the public were offered to the public were offered to the public
exceeds the amount of any damages which underwriter has otherwise been required
to  pay  by  reason  of  such untrue or alleged untrue statement or omission or
alleged omission.  No person guilty of fraudulent misrepresentation (within the
meaning  of  Section  11(f)  of  the  Securities  Act)  shall  be  entitled  to
contribution  from  any  person  who   was   not   guilty  of  such  fraudulent
misrepresentation.  The obligation of any underwriters  to  contribute pursuant
to  this  Section  7.7(e)  shall  be several in proportion to their  respective
underwriting commitments and not joint.

            7.8 REPORTS UNDER EXCHANGE ACT.  With a view to making available to
the Holders the benefits of Rule 144  promulgated  under the Securities Act and
any other rule or regulation of the SEC that may at any time permit a Holder to
sell Registrable Securities to the public without registration, and with a view
to  making  it  possible  for  any  such  Holder  to register  the  Registrable
Securities pursuant to a registration on Form S-3, the Company agrees to:

                  (a)  use its best efforts to take such action as is necessary
to enable a Holder to utilize Form S-3 for the sale of Registrable Securities;

                  (b)  use its best efforts to file  with  the  SEC in a timely
manner  all  reports  and  other  documents  required of the Company under  the
Securities Act and the Exchange Act; and

                  (c)  Furnish to a Holder owning  any  Registrable  Securities
upon  request  (i)  a  written  statement  by  the Company as to whether it has
complied with the reporting requirements of the Securities Act and the Exchange
Act, or that it qualifies as a registrant whose  Registrable  Securities may be
resold pursuant to Form S-3 (at any time after it so qualifies), (ii) a copy of
the  most  recent  annual  or  quarterly  report of the Company and such  other
reports and documents so filed by the Company, and (iii) such other information
as may be reasonably required in availing any  Holder of Registrable Securities
of any such Registrable Securities without registration  or  pursuant  to  such
form.

            7.9 TRANSFERABILITY.   The  right  to cause the Company to register
Registrable  Securities  granted  by  the Company to  the  Holders  under  this
Agreement may be assigned by any Holder  to  a  transferee  or  assignee of any
Registrable  Securities, provided that the Company must receive written  notice
prior to or at  the time of said transfer, stating the name and address of said
transferee or assignee  and  identifying  the  securities with respect to which
such rights are being assigned.  The limitations  set  forth  in this Section 7
with respect to registration rights shall apply to all transferees or assignees
of Registrable Securities.

     WHEREAS:

     A.   The Company and  the  Buyer  are  executing  and  delivering this
Agreement  in  reliance  upon  the  exemption  from securities registration
afforded by Rule 506 under Regulation D ("REGULATION  D") as promulgated by
the United States Securities and Exchange Commission (the  "SEC") under the

and conditions stated in this Agreement, (i) shares of the Company's common
stock,  par  value  $.01 per share (the "COMMON STOCK"), and (ii) shares of
the Company's preferred  stock,  $.01  par  value per share (the "PREFERRED
STOCK"); and

     C.   Contemporaneous with the issuance of the Preferred Stock pursuant
to this Agreement, the Company is issuing to  the Buyer certain warrants to
purchase shares of the Common Stock (the "WARRANTS"),   and contemporaneous
with  the  closing  pursuant  to  this  Agreement, the parties  hereto  are
executing and delivering a Registration Rights Agreement (the "REGISTRATION

certain   registration  rights  under  the  1933  Act  and  the  rules  and

     NOW THEREFORE, the Company and the Buyer hereby agrees as follows:

1.   PURCHASE AND SALE OF COMMON STOCK AND PREFERRED STOCK.

     a.   PURCHASE  OF  COMMON  STOCK.  The Company shall issue and sell to
the Buyer and the Buyer shall purchase  1,094,890  shares  of  Common Stock

and nine-tenths  percent  (4.9%) of the outstanding shares of Common Stock.
The per share purchase price for the Common Shares shall be $2.74, which is
equal to eighty percent (80%)  of  the  average  (rounded  to  the  nearest
thousandth)  closing  bid  price  for  the  Common Stock as reported on the
National  Association  of Securities Dealers Automated  Quotation  National
Market System ("NASDAQ-NMS")  during  the five (5) consecutive trading days
ending one trading day prior to the Closing  Date,  as  defined below (such
closing bid price being the "CLOSING DATE AVERAGE MARKET PRICE").

     b.   PURCHASE OF PREFERRED STOCK.  The Company shall issue and sell to
the  Buyer  and  the  Buyer  shall  purchase  40,000  shares  of  Series  B

without separate consideration,  the Warrants to purchase 638,686 shares of
Common Stock (the "WARRANT SHARES").   The  exercise  price of the Warrants
shall be $4.11 per Warrant Share.  The Warrants shall expire five (5) years

1996, respectively, and shall deliver the Warrants on February 7, 1996, all
to Buyer's counsel,  no  later  than 4:00 p.m. Eastern Standard Time on the
respective dates.

     f.   CLOSING DATE.  The date  and time of the issuance and sale of the
Common Shares (the "CLOSING DATE") shall  be  no  later  than  4:00 Eastern

only  and not with a view towards the public sale or  distribution  thereof
except pursuant to sales registered under the 1933 Act.

     b.   ACCREDITED   INVESTOR   STATUS.   The  Buyer  is  an  "accredited
investor" as that term is defined in Rule 501(a)(3) of Regulation D.

     c.   RELIANCE  ON  EXEMPTIONS.    The   Buyer   understands  that  the
Securities  are  being  offered  and  sold  to it in reliance  on  specific
exemptions from the registration requirements  of United States federal and
state securities laws and that the Company is relying  upon  the  truth and
accuracy   of,  and  the  Buyer's  compliance  with,  the  representations,
warranties, agreements, acknowledgments and understandings of the Buyer set
forth herein  in order to determine the availability of such exemptions and
the eligibility of the Buyer to acquire the Securities.

     d.   INFORMATION.   The  Buyer  and  its  advisors,  if any, have been
furnished  with  all  materials  relating  to  the  business, finances  and
operations of the Company and materials relating to the  offer  and sale of
the Securities which have been requested by the Buyer.  The Buyer  and  its
advisors,  if  any,  have been afforded the opportunity to ask questions of
the Company and have received complete and satisfactory answers to any such
inquiries.  The Buyer  understands  that  its  investment in the Securities
involves a high degree of risk.

     e.   GOVERNMENTAL REVIEW.  The Buyer understands that no United States
federal or state agency or any other government  or governmental agency has
passed on or made any recommendation or endorsement of the Securities.

     f.   TRANSFER OR RESALE.  The Buyer understands  that  (i)  except  as
provided  in  the  Registration  Rights  Agreement,  the Common Shares, the
Preferred Shares, the Conversion Shares, the Warrants,  the Warrant Shares,

Section 2(c) of the Registration Rights Agreement and pursuant  to  Section
(2)(b)  of  the  Certificate  of  Designation  (collectively,  the  "DAMAGE
SHARES")  have not been and are not being registered under the 1933 Act  or
any  state  securities   laws,  and  may  not  be  transferred  unless  (a)
subsequently registered thereunder,  or  (b) the Buyer shall have delivered
to  the  Company an opinion of counsel, reasonably  satisfactory  in  form,
scope and substance to the Company, to the effect that the securities to be
sold or transferred  may  be  sold  or transferred pursuant to an exemption
from such registration; (ii) any sale  of  such securities made in reliance
on Rule 144 promulgated under the 1933 Act may  be  made only in accordance
with the terms of said Rule and further, if said Rule  is  not  applicable,
any  resale of such securities under circumstances in which the seller  (or
the person  through  whom  the  sale  is  made)  may  be  deemed  to  be an
underwriter  (as  that  term  is  defined  in  the  1933  Act)  may require
compliance  with  some other exemption under the 1933 Act or the rules  and
regulations of the  SEC  thereunder;  and (iii) neither the Company nor any
other person is under any obligation to  register  such  securities  (other
than  pursuant to the Registration Rights Agreement) under the 1933 Act  or
any state securities laws or to comply with the terms and conditions of any
exemption thereunder.

     g.   LEGENDS.   The Buyer understands that the Warrants, the Preferred
Shares and, until such  time  as  the Common Shares, the Conversion Shares,
the Warrant Shares, and the Damage  Shares  (collectively, the "REGISTRABLE
SECURITIES") have been registered under the 1933 Act as contemplated by the
Registration Rights Agreement, the stock certificates  for  the Registrable
Securities  may  bear  a restrictive legend in substantially the  following
form (and a stop-transfer  order  may  be  placed  against transfer of such
stock certificates):

     The  securities  represented by this certificate  have  not  been
     registered under the  Securities  Act  of  1933, as amended.  The
     securities have been acquired for investment and may not be sold,
     transferred   or   assigned  in  the  absence  of  an   effective
     registration statement  for  the securities under said Act, or an
     opinion of counsel, reasonably  satisfactory  in  form, scope and
     substance to the Company, that registration is not required under
     said Act.

validly authorized, executed and delivered  on behalf of the Buyer and is a
valid and binding agreement of the Buyer enforceable in accordance with its

     d.   ISSUANCE  OF SHARES.  The Registrable Securities,  the  Preferred
Shares  and  the  Warrants  are  duly  authorized  and,  upon  issuance  in
accordance with the  terms  hereof  and  thereof,  shall be validly issued,
fully paid and non-assessable, and free from all taxes,  liens  and charges
with respect to the issue thereof.

     e.   NO  CONFLICTS.  The execution, delivery and performance  of  this
Agreement by the  Company  and  the  consummation  by  the  Company  of the
transactions contemplated hereby will not (i) result in a violation of  the
Certificate   of  Incorporation  or  By-laws  or  (ii)  conflict  with,  or
constitute a default  (or  an  event  which with notice or lapse of time or
both  would  become a default) under, or  give  to  others  any  rights  of
termination, amendment,  acceleration  or  cancellation  of, any agreement,
indenture or instrument to which the Company or any of its  subsidiaries is
a  party,  or  result  in a violation of any law, rule, regulation,  order,
judgment  or  decree (including  federal  and  state  securities  laws  and
regulations) applicable  to  the  Company  or any of its subsidiaries or by
which any property or asset of the Company or  any  of  its subsidiaries is
bound  or  affected  (except  for  such  conflicts, defaults, terminations,
amendments,  accelerations,  cancellations and  violations  as  would  not,
individually or in the aggregate,  have  a  Material  Adverse Effect).  The
businesses of the Company and its subsidiaries are not being conducted, and
shall  not  be  conducted  through  the  date  of  the  expiration  of  any
unexercised  Warrants  issued  to  the  Buyer,  in  violation of  any  law,
ordinance  or  regulation of any governmental entity, except  for  possible
violations which  either  singly or in the aggregate do not have a Material
Adverse Effect.  Except as  required  under the 1933 Act and any applicable
state securities laws, the Company is not  required  to obtain any consent,
authorization  or  order of, or make any filing or registration  with,  any
court or governmental agency in order for it to execute, deliver or perform
any of its obligations  under  this  Agreement in accordance with the terms
hereof.

     f.   SEC DOCUMENTS, FINANCIAL STATEMENTS.   Since  June  30, 1992, the
Company  has  filed  all  reports,  schedules, forms, statements and  other
documents required to be filed by it with the SEC pursuant to the reporting
requirements of the Exchange Act of 1934,  as amended (the "1934 ACT") (all
of the foregoing filed prior to the date hereof  and  all exhibits included
therein and financial statements and schedules thereto and documents (other
than  exhibits)  incorporated  by  reference  therein,  being   hereinafter
referred  to herein as the "SEC DOCUMENTS").  The Company has delivered  to
the Buyer true  and  complete  copies of the SEC Documents, except for such
exhibits, schedules and incorporated  documents.   As  of  their respective
dates,  the  SEC  Documents  complied  in  all  material respects with  the
requirements  of  the  1934 Act and the rules and regulations  of  the  SEC
promulgated thereunder applicable to the SEC Documents, and none of the SEC
Documents, at the time they  were  filed with the SEC, contained any untrue
statement of a material fact or omitted  to  state a material fact required
to be stated therein or necessary in order to  make the statements therein,
in light of the circumstances under which they were  made,  not misleading.
As  of  their  respective  dates,  the financial statements of the  Company
included in the SEC Documents complied  as to form in all material respects
with  applicable  accounting  requirements  and  the  published  rules  and
regulations  of the SEC with respect thereto.   Such  financial  statements
have  been  prepared  in  accordance  with  generally  accepted  accounting
principles, consistently  applied,  during the periods involved (except (i)
as may be otherwise indicated in such  financial  statements  or  the notes
thereto, or (ii) in the case of unaudited interim statements, to the extent
they  may include footnotes or may be condensed or summary statements)  and
fairly present in all material respects the consolidated financial position
of the  Company  and  its consolidated subsidiaries as of the dates thereof
and the consolidated results  of  their  operations  and cash flows for the
periods then ended (subject, in the case of unaudited statements, to normal
year-end audit adjustments). No other information provided  by or on behalf
of  the  Company  to  the  Buyer  and  referred to in Section 2(d) of  this
Agreement, when made, contained any untrue  statement of a material fact or
omitted  to  state  any  material  fact necessary  in  order  to  make  the
statements therein, in the light of  the circumstance under which they were
made, not misleading.  In the aggregate,  the information provided by or on
behalf  of  the  Company  to the Buyer and referred  to  in  Section  2(d),
including without limitation  the  SEC  Documents, does not omit to state a
material fact or contain material inaccuracies.

     g.   ABSENCE OF CERTAIN CHANGES.  Since  June 30, 1995, there has been
no  material  adverse  change and no material adverse  development  in  the
business,  properties,  operations,   financial   condition,   results   of
operations  or  prospects  of  the  Company,  except  as  disclosed  in the
documents referred to in Section 2(d) hereof or in the SEC Documents.
     h.   ABSENCE  OF  LITIGATION.   Except  as disclosed in SCHEDULE 3(H),
there is no action, suit, proceeding,inquiry or  investigation before or by
any court, public board or body pending or, to the knowledge of the Company
or any of its subsidiaries, threatened against or  affecting the Company or
any of its subsidiaries, wherein an unfavorable decision, ruling or finding
would have a Material Adverse Effect or which would  adversely  affect  the
validity  or  enforceability of, or the authority or ability of the Company
to perform its  obligations  under,  this Agreement or any of the documents
contemplated herein.

4.   COVENANTS.

     a.   BEST EFFORTS.  The parties shall use their best efforts timely to
satisfy  each of the conditions described  in  Section  6  and  7  of  this
Agreement.

     b.   FORM  D; BLUE SKY LAWS.  The Company agrees to file a Form D with
respect to the Securities  as  required under Regulation D and to provide a
copy thereof to the Buyer promptly  after  such filing.  The Company shall,
on  or  before  the Closing Date, take such action  as  the  Company  shall
reasonably determine  is necessary to qualify the Securities for, or obtain
exemption for the Securities for, sale to the Buyer at the closing pursuant
to this Agreement under  applicable  securities  or  "blue sky" laws of the
states of the United States, and shall provide evidence  of any such action
so taken to the Buyer on or prior to the Closing Date.

     c.   REPORTING STATUS.  Until such date as is the earlier  of  (i)  at
least three (3) years after the date of the expiration of all the Warrants,
or  (ii)  the  date on which (a) all of the Warrants have been exercised or
expired, (b) no  Registrable  Securities  are held by any Investor (as that
term is defined in the Registration Rights  Agreement), and (c) none of the
Preferred Shares is outstanding (the "REGISTRATION  PERIOD"),  the  Company
shall  file  all reports required to be filed with the SEC pursuant to  the
1934 Act, and  the  Company  shall  not  terminate  its status as an issuer
required to file reports under the 1934 Act even if the  1934  Act  or  the
rules and regulations thereunder would permit such termination.

     d.   USE  OF  PROCEEDS.  Without the consent of a majority in interest
of the Registrable Securities,  the Company shall not use the proceeds from
the sale of the Common Shares and  the  Preferred Shares for anything other
than  the  Company's  internal  working capital  purposes  and  shall  not,
directly or indirectly, use such  proceeds for any loan to or investment in
any other corporation, partnership,  enterprise  or  other person; provided
that it is understood that the Company may be required  to  pay  a finder's
fee in connection with the transactions provided for herein.

     e.   ADDITIONAL EQUITY CAPITAL.  The Company agrees that, for a period
of  180 days following February 7, 1996, the Company will not, without  the
prior written approval of the Buyer, negotiate or contract with any outside
party  to issue additional equity financing in any form, provided that such
restriction  shall  not  apply  to  the  issuance  of  equity securities in
connection with a license or development agreement between  the  Company or
one of its subsidiaries and a corporate strategic partner.  Notwithstanding
the  foregoing,  during  such 180 day period the Company may negotiate  and
contract with an outside party  to  obtain  up  to $3,000,000 of additional
equity  capital  provided that (i) no sale of such  securities  shall  take
place unless the Company first offers such securities to the Buyer on terms
no less favorable  in  any  respect  than those subsequently offered to the
eventual  purchaser  and  the Buyer declines  such  purchase  or  does  not
exercise its right to purchase  all  of  the  securities  so offered within
fifteen  (15) days of receiving a written offer in reasonable  detail  from
the Company;  provided that, the Buyer shall not have the right to purchase
only a portion  of  the  offered  securities  but  must purchase all of the
securities  offered,  (ii) the terms and conditions on  which  such  equity
securities are sold shall not be more favorable to the purchaser than those
under which the Buyer is  purchasing  the  Common  Shares and the Preferred
Shares,  and  (iii)  the  sale  by such outside party of  any  such  equity
securities shall not be registered  on  the  same registration statement as
registers the sale of the Registrable Securities.

     f.   EXPENSES.   The  Company  shall  pay  all  expenses  incurred  in
connection  with  the  negotiation,  preparation, execution,  delivery  and
performance  of  this  Agreement  and the  Registration  Rights  Agreement,
including, without limitation, Buyer's  attorneys'  fees and expenses up to
an aggregate amount of Forty Thousand Dollars ($40,000).

     g.   REVERSE STOCK SPLIT.  The Company agrees to  use its best efforts
to  effect a reverse one-for-two stock split of the outstanding  shares  of
Common  Stock  as  soon as practicable after the Closing Date.  The Company
shall not be required  to  seek  stockholder  approval  prior to the annual
meeting thereof.

     h.   FINANCIAL INFORMATION.  The Company agrees to send  the following
reports  to the Buyer until the Buyer transfers, assigns, or sells  all  of
the Securities,  Conversion Shares, Warrant Shares, and Damage Shares:  (i)
within ten (10) days  after  the  filing with the SEC, a copy of its Annual
Report on Form 10-K, its Quarterly  Reports  on  Form  10-Q and any Current
Reports on Form 8-K; and (ii) within one day after release,  copies  of all
press releases issued by the Company or any of its subsidiaries.

     i.   RESERVATION  OF  SHARES.   The  Company  shall  at all times have
authorized,  and reserved for the purpose of issuance, a sufficient  number
of shares of Common  Stock  to  provide  for  the exercise of the Warrants,
conversion of the Preferred Shares and issuance of the Damage Shares.

     j.   LISTING.  The Company shall promptly  secure  the  listing of the
Registrable Securities upon each national securities exchange  or automated
quotation system, if any, upon which shares of Common Stock are then listed
(subject to official notice of issuance) and shall maintain, so long as any
other shares of Common Stock shall be so listed, such listing of all shares
of  Registrable  Securities  from time to time issuable under the terms  of
this Agreement and the Registration Rights Agreement.

     k.   MAJOR TRANSACTIONS.   The  Company  shall  not consummate a Major
Transaction  (as  that term is defined in the Certificate  of  Designation)
without the prior written  approval  of  the  holders  of a majority of the
Preferred Shares; PROVIDED, HOWEVER, that this Section shall  terminate and
be of no further force and effect if the Company reasonably determines that
performance  hereunder  would  violate  NASDAQ  rules  with  regard to  the
issuance of voting securities having super-majority voting rights.

5.   TRANSFER AGENT INSTRUCTIONS.

     The  Company  shall instruct its transfer agent to issue certificates,
registered in the name  of  the  Buyer  or  its nominee, for the Conversion
Shares, Warrant Shares and Damage Shares in such  amounts as specified from
time to time by the Company to the transfer agent in  accordance  with  the
terms  of  the  applicable  security.   Prior  to  sale  of the Registrable
Securities,  pursuant  to  an  effective  registration statement  all  such
certificates shall bear the restrictive legend specified in Section 2(g) of
this Agreement.  The Company shall provide  instructions  and  opinions  of
counsel  to  its  transfer  agent  in  accordance  with Section 3(o) of the
Registration Rights Agreement.  The Company warrants  that  no  instruction
other  than  such  instructions  referred  to  in  this Section 5, and stop
transfer  instructions  to  give  effect to Section 2(f)  hereof  prior  to
registration of the Registrable Securities  under  the  1933  Act,  will be
given by the Company to its transfer agent and that the Securities and  the
Registrable  Securities shall otherwise be freely transferable on the books
and records of  the Company as and to the extent provided in this Agreement
and the Registration  Rights  Agreement.   Nothing  in  this  Section shall
affect in any way the Buyer's obligations and agreement to comply  with all
applicable   securities   laws  upon  resale  of  the  Securities  and  the
Registrable Securities.  If  the Buyer provides the Company with an opinion
of counsel, reasonably satisfactory  in  form,  scope  and substance to the
Company,  that  registration  of  a  resale  by  the  Buyer of any  of  the
Securities  or the Registrable Securities is not required  under  the  1933
Act, the Company  shall permit the transfer, and, in the case of the Common
Shares, the Preferred  Shares, the Conversion Shares, the Warrant Shares or
the Damage Shares, promptly  instruct  its  transfer  agent to issue one or
more certificates in such name and in such denominations  as  specified  by
the Buyer.

          time  after  seventy (70) days after the date of issuance (or, if
          such Series B  Preferred  Share  is called for redemption, at any
          time up to and including, but not after, the close of business on
          the fifth full business day prior  to  the  date  fixed  for such
          redemption,  unless  default  shall  be  made  by  the Company in
          providing  the  funds  for the payment of the redemption  price),
          into  fully  paid and nonassessable  shares  (calculated  to  the
          nearest  whole   share)   of  Common  Stock  of  the  Company  as
          constituted at the time of  such  conversion,  at  the conversion
          price  (the  "CONVERSION  PRICE")  in  effect  at  the  time   of
          conversion determined as hereinafter provided; PROVIDED, HOWEVER,
          that in no event shall any holder be entitled to convert Series B
          Preferred  Shares if, after giving effect to such conversion, the
          number of shares  of  Common  Stock  purchased  pursuant  to  the
          Securities Purchase Agreement dated January 31, 1996 by and among
          the  Company  and  certain  investors  (the  "SECURITIES PURCHASE
          AGREEMENT")  set  forth  therein  providing for the  purchase  of
          Common  Stock,  the Series B Preferred  Shares  and  Warrants  or
          issued on exercise  of  such  Warrants, or conversion of Series B
          Preferred Shares and beneficially  owned  by  such holder and all
          other holders whose holdings would be aggregated with such holder
          for  purposes of calculating beneficial ownership  in  accordance
          with Sections  13(d)  and  16  of  the Securities Exchange Act of
          1934, as amended, and the regulations thereunder ("SECTIONS 13(D)
          AND 16"), including, without limitation, any person serving as an
          adviser  to  any holder (collectively,  the  "RELATED  PERSONS"),
          would  exceed  four   and   nine-tenths  percent  (4.9%)  of  the
          outstanding shares of Common Stock (calculated in accordance with
          Sections 13(d) and 16).  Common Stock issuable upon conversion of
          Series B Preferred Shares or  exercise  of  the  warrants for the
          purchase  of  Common  Stock  held  by such holder or the  Related
          Persons  shall  not be deemed to be beneficially  owned  by  such
          holder or the Related  Persons for this purpose.   Each Preferred
          Share shall have a value  of  $100  (the  "STATED VALUE") for the
          purpose  of such conversion and the number of  shares  of  Common
          Stock issuable  upon conversion of each of the Series B Preferred
          Shares shall be determined  by  dividing the Stated Value thereof
          by the Conversion Price then in effect.   Every  reference herein
          to the COMMON STOCK of the Company (unless a different  intention
          is expressed) shall be to the shares of the Common Stock  of  the
          Company,  $.01  par value, as such stock exists immediately after
          the  issuance of the  Series  B  Preferred  Shares  provided  for
          hereunder,  or  to  stock  into  which  such  Common Stock may be
          changed from time to time thereafter.

                    (b)  The Conversion Price shall be eighty percent (80%)
          (the  "CONVERSION  PERCENTAGE") of the Average Market  Price  (as
          defined below) for the  Common Stock for the five (5) consecutive
          trading  days  ending one trading  day  prior  to  the  date  the
          Conversion Notice  (as defined below) is received by the Company,
          subject to adjustment  as  provided  herein.  If the registration
          statement (the "REGISTRATION STATEMENT")  covering  the shares of
          Common  Stock issuable upon conversion of the Series B  Preferred
          Shares required  to  be  filed  by  the  Company  pursuant to the
          Registration  Rights  Agreement  between the Company and  initial
          holders  of  the  Series B Preferred  Shares  (the  "REGISTRATION
          RIGHTS AGREEMENT")  has  not  been declared effective by the U.S.
          Securities and Exchange Commission  ("SEC")  within  ninety  (90)
          days after the date of issuance of the Series B Preferred Shares,
          or  if,  after  the  Registration  Statement  has  been  declared
          effective  by  the  SEC,  sales  cannot  be  made pursuant to the
          Registration  Statement  by reason of stop order,  the  Company's
          failure to update the Registration  Statement or otherwise, or if
          the Common Stock is not listed or included  for  quotation on the
          National  Association  of Securities Dealers Automated  Quotation
          ("NASDAQ") National Market  System  (the  "NASDAQ-NMS"),  the New
          York  Stock  Exchange  (the  "NYSE"), the American Stock Exchange
          (the  "AMEX"),  or  the  NASDAQ  SmallCap   Market  (the  "NASDAQ
          SMALLCAP") then, as partial relief for the damages  to the holder
          by  reason  of  any such delay in or reduction of its ability  to
          sell the shares of  Common  Stock  (which  remedy  shall  not  be
          exclusive  of  any  other remedies available at law or in equity,
          except that such remedy  shall  be  the  exclusive remedy for any
          delay in the effectiveness of the Registration Statement provided
          the  Registration  Statement  is declared effective  by  the  SEC
          within  180 days after the date  of  issuance  of  the  Series  B
          Preferred  Shares), the Conversion Percentage shall be reduced by
          a number of  percentage  points  equal to three (3) times the sum
          of: (i) the number of months (prorated  for partial months) after
          the  end  of  such  90  day  period  and prior to  the  date  the
          Registration  Statement  is  declared  effective   by   the  SEC,
          provided, however, that there shall be excluded from such  period
          (and  from  any  period under clause (ii) immediate below) delays
          which are attributable  to  changes in the Registration Statement
          required  by  the Investors (as  that  term  is  defined  in  the
          Registration Rights  Agreement),  including,  without limitation,
          changes  in the plan of distribution; (ii) the number  of  months
          (prorated  for partial months) that sales cannot be made pursuant
          to the Registration  Statement  (by  reason  of  stop  order, the
          Company's failure to update the Registration or otherwise)  after
          the Registration Statement has been declared effective; and (iii)
          the  number  of  months  (prorated  for  partial months) that the
          Common  Stock  is  not listed or included for  quotation  on  the
          NASDAQ-NMS, NYSE, AMEX, or NASDAQ SmallCap after the Registration
          Statement  has  been  declared   effective;   provided  that  the
          aggregate number of months that are the basis of  a  reduction in
          the Conversion Percentage pursuant to the foregoing clauses  (i),
          (ii)  and  (iii)  shall not exceed twelve (12).  (For example, if
          the Registration Statement  becomes  effective  one  and one-half
          (1  1/2  )  months  after  the  end  of  such  90 day period, the
          Conversion   Percentage  would  be  75.5%  until  any  subsequent
          adjustment; if thereafter sales could not be made pursuant to the
          Registration Statement  for  a  period  of  two  (2)  months, the
          Conversion  Percentage  would  then  be  69.5%.)   If  the holder
          converts  Series  B  Preferred  Shares  into Common Stock and  an
          adjustment to the Conversion Percentage is required subsequent to
          such conversion, but prior to the sale of  such  Common  Stock by
          such  holder,  the Company shall pay to such holder, within  five
          (5) days after receipt  of  a  notice  of the sale of such Common
          Stock from such holder, an amount equal  to  the  Average  Market
          Price of the Common Stock obtained upon conversion of such Series
          B  Preferred Shares for the five (5) trading days ending one  (1)
          trading  day prior to the date of conversion multiplied by three-
          hundredths (.03) times the number of months (prorated for partial
          months) for  which  an adjustment was required; provided that the
          aggregate  number of months  for  which  such  an  adjustment  is
          required (when  added  to  the  number  of  months  for  which an
          adjustment is made pursuant to clauses (i), (ii) and (iii) above)
          shall  not  exceed  twelve (12).  Such amount may be paid at  the
          Company's option in cash  or  Common  Stock  valued  based on the
          Average Market Price of the Common Stock for the period  of  five
          (5)  consecutive  trading  days ending on the date of the sale of
          such Common Stock; PROVIDED,  HOWEVER, that any amounts due as to
          that period during which the shares  are  not  traded or included
          for  quotation  on the NASDAQ-NMS, NYSE, AMEX or NASDAQ  SmallCap
          shall be paid in  cash  only; PROVIDED, FURTHER, HOWEVER, that in
          no event shall shares be issued hereunder if, after giving effect
          to such issuance, the number  of shares of Common Stock purchased
          pursuant  to  the  Securities Purchase  Agreement  or  issued  on
          exercise of the Warrants  or conversion of the Series B Preferred
          Shares and beneficially owned  by  such  holder  and  all Related
          Persons would exceed four and nine-tenths percent (4.9%)  of  the
          outstanding shares of Common Stock (calculated in accordance with
          Sections  13(d)  and 16; cash shall be paid in lieu of any shares
          which cannot be issued  pursuant  to this second proviso.  Common
          Stock issuable upon conversion of Series  B  Preferred  Shares or
          exercise of the warrants for the purchase of Common Stock held by
          such  holder  or  the  Related Persons shall not be deemed to  be
          beneficially owned by such holder or the Related Persons for this
          purpose. (For example, if  the Conversion Percentage was 75.5% at
          the time of conversion of $1,000,000  in Stated Value of Series B
          Preferred Shares (such that the Series  B  Preferred  Shares were
          converted  into  Common Stock having an Average Market Price  for
          the applicable period  in aggregate of $1,324,503) and subsequent
          to conversion there was  a  further  two  (2)  month delay in the
          Registration  Statement's  being  declared  effective,  and  such
          Common Stock was sold at the end of such two  (2)  month  period,
          the  Company would pay to the holder $79,470.20 in cash or Common
          Stock.)

                    "AVERAGE  MARKET  PRICE" of any security for any period
          shall be computed as the arithmetic  average  of  the closing bid
          prices for such security for each trading day in such  period  on
          the  NASDAQ-NMS,  or,  if  the  NASDAQ-NMS  is  not the principal
          trading market for such security, on the principal trading market
          for such security, or, if market value cannot be  calculated  for
          such  period  on  any  of  the  foregoing bases, the average fair
          market value during such period as  reasonably determined in good
          faith by the Board of Directors of the Company.

                    (c)  If  the Company shall consolidate  with  or  merge
          into any corporation  or  reclassify  its  outstanding  shares of
          Common  Stock  (other than by way of subdivision or reduction  of
          such shares) (each  a  "MAJOR  TRANSACTION"),  then each Series B
          Preferred Share shall thereafter be convertible  into  the number
          of shares of stock or securities (the "RESULTING SECURITIES")  or
          property  of  the  Company,  or of the entity resulting from such
          consolidation or merger, to which  a  holder  of  the  number  of
          shares of Common Stock delivered upon conversion of such Series B
          Preferred   Share  would  have  been  entitled  upon  such  Major
          Transaction had  the  holder  of  such  Series  B Preferred Share
          exercised its right of conversion and had such Common  Stock been
          issued  and  outstanding  and had such holder been the holder  of
          record  of  such  Common  Stock   at   the  time  of  such  Major
          Transaction, and the Company shall make lawful provision therefor
          as  a  part  of such consolidation, merger  or  reclassification;
          PROVIDED, HOWEVER, that the Company shall give the holders of the
          Series B Preferred Shares written notice of any Major Transaction
          promptly upon  the  execution  of  any  agreement  whether or not
          binding  in connection therewith (including without limitation  a
          letter of intent or agreement in principle) and in no event shall
          a Major Transaction  be  consummated  prior  to  ninety (90) days
          after such notice.

                    (d)  The  Company  shall  not issue any fraction  of  a
          share of Common Stock upon any conversion,  but shall pay in cash
          therefor  at  the Conversion Price then in effect  multiplied  by
          such fraction.

                    (e)  On  presentation  and surrender to the Company (or
          at any office or agency maintained for the transfer of the Series
          B Preferred Shares) of the certificates  of  Series  B  Preferred
          Shares so to be converted, duly endorsed in blank for transfer or
          accompanied  by  proper instruments of assignment or transfer  in
          blank (a "CONVERSION  NOTICE"),  with  signatures guaranteed, the
          holder  of  such  Series B Preferred Shares  shall  be  entitled,
          subject  to  the limitations  herein  contained,  to  receive  in
          exchange therefor  a  certificate  or certificates for fully paid
          and nonassessable shares, which certificates  shall  be delivered
          by  the  second  trading  day  after the date of delivery of  the
          Conversion  Notice, and cash for  fractional  shares,  of  Common
          Stock on the  foregoing  basis.   The  Series  B Preferred Shares
          shall be deemed to have been converted, and the person converting
          the same to have become the holder of record of Common Stock, for
          all purposes as of the date of delivery of the Conversion Notice.

                    (f)  The Company shall, so long as any  of the Series B
          Preferred Shares are outstanding, reserve and keep  available out
          of  its  authorized  and  unissued  Common Stock, solely for  the
          purpose of effecting the conversion of  the  Series  B  Preferred
          Shares, such number of shares of Common Stock as shall from  time
          to  time  be  sufficient  to  effect the conversion of all of the
          Series B Preferred Shares then outstanding.

                    (g)  The Company shall  pay any and all taxes which may
          be imposed upon it with respect to  the  issuance and delivery of
          Common Stock upon the conversion of the Series B Preferred Shares
          as herein provided.  The Company shall not  be  required  in  any
          event  to  pay  any  transfer  or  other  taxes  by reason of the
          issuance of such Common Stock in names other than  those in which
          the  Series  B  Preferred  Shares surrendered for conversion  are
          registered on the Company's  records,  and  no such conversion or
          issuance  of  Common  Stock shall be made unless  and  until  the
          person requesting such  issuance  has  paid  to  the  Company the
          amount of any such tax, or has established to the satisfaction of
          the  Company  and  its transfer agent, if any, that such tax  has
          been paid.

               (3)  VOTING RIGHTS.   Holders  of  Series B Preferred Shares
          shall have no voting rights, except as required  by  law  and  by
          Section 7 hereof.

               (4)  REDEMPTION.    The   Company  may,  but  shall  not  be
          obligated to, at any time subsequent  to  ninety  (90) days after
          the issuance of the Series B Preferred Shares, redeem  the  whole
          or any part of the Series B Preferred Shares then outstanding  at
          a  redemption  price  of  $127 per Preferred Share, in accordance
          with the following redemption procedures:

                    (a)  In case of redemption of only part of the Series B
          Preferred  Shares  at any time  outstanding,  the  Company  shall
          designate the amount  of  Series  B  Preferred  Shares  so  to be
          redeemed and shall redeem such Series B Preferred Shares on a PRO
          RATA  basis.   Subject  to  the limitations and provisions herein
          contained,  the  Board of Directors  shall  have  the  power  and
          authority to prescribe  the  terms  and conditions upon which the
          Series B Preferred Shares shall be redeemed from time to time.

                    (b)  Notice of every redemption  shall be given by mail
          to every holder of record of any Series B Preferred  Shares  then
          to  be  redeemed,  at  least thirty (30), but no more than ninety
          (90), days prior to the date fixed as the date for the redemption
          thereof, at the respective  addresses of such holders as the same
          shall appear on the stock transfer  books  of  the  Company.  The
          notice  shall state that the Series B Preferred Shares  shall  be
          redeemed  by the Company at the redemption price specified above,
          upon the surrender  for  cancellation,  at  the  time  and  place
          designated  in  such notice, of the certificates representing the
          Series B Preferred  Shares  to  be redeemed, properly endorsed in
          blank  for  transfer, or accompanied  by  proper  instruments  of
          assignment and transfer in blank, with signatures guaranteed, and
          bearing all necessary  transfer  tax  stamps  thereto affixed and
          cancelled.   On  and  after  the  date  specified in  the  notice
          described above, each holder of Series B  Preferred Shares called
          for  redemption  shall  be  entitled  to  receive   therefor  the
          specified redemption price upon presentation and surrender at the
          place designated in such notice of the certificates for  Series B
          Preferred  Shares  called  for  redemption, properly endorsed  in
          blank  for  transfer  or accompanied  by  proper  instruments  of
          assignment or transfer  in blank, with signatures guaranteed, and
          bearing all necessary transfer  tax  stamps  thereto  affixed and
          cancelled.

                    (c)  If the Company shall give notice of redemption  as
          aforesaid   (and  unless  the  Company  shall  fail  to  pay  the
          redemption price  of  the Series B Preferred Shares presented for
          redemption  in  accordance   with  such  notice),  all  Series  B
          Preferred Shares called for redemption  shall  be  deemed to have
          been  redeemed on the date specified in such notice,  whether  or
          not the  certificates for such Series B Preferred Shares shall be
          surrendered for redemption, and such Series B Preferred Shares so
          called for  redemption  shall  from  and after such date cease to
          represent any interest whatsoever in the Company or its property,
          and the holders thereof shall have no rights other than the right
          to  receive such redemption price without  any  interest  thereof
          from and after such date.

               (5)  LIQUIDATION,  DISSOLUTION, WINDING UP.  In the event of
          any voluntary or involuntary  liquidation, dissolution or winding
          up of the Company, the holders  of  the Series B Preferred Shares
          shall be entitled to receive in cash  out  of  the  assets of the
          Company,  whether  from  capital or from earnings, available  for
          distribution to its stockholders  (the "PREFERRED FUNDS"), before
          any amount shall be paid to the holders  of  the Common Stock, an
          amount  equal to the Stated Value per Series B  Preferred  Share,
          provided that, if the Preferred Funds are insufficient to pay the
          full amount  due  to the holders of Series B Preferred Shares and
          holders of shares of  other  classes or series of preferred stock
          of the Company that are of equal rank with the Series B Preferred
          Shares  as  to  payments  of Preferred  Funds  (the  "PARI  PASSU
          SHARES"), then each holder  of Series B Preferred Shares and Pari
          Passu Shares shall receive a  percentage  of  the Preferred Funds
          equal  to  the  full  amount of Preferred Funds payable  to  such
          holder as a percentage  of  the  full  amount  of Preferred Funds
          payable  to  all  holders of Series B Preferred Shares  and  Pari
          Passu Shares.   The  purchase  or  redemption  by  the Company of
          stock  of any class, in any manner permitted by law,  shall  not,
          for  the   purposes   hereof,   be  regarded  as  a  liquidation,
          dissolution  or  winding  up  of  the   Company.    Neither   the
          consolidation  nor  merger  of the Company with or into any other
          corporation or corporations,  nor  the  sale  or  transfer by the
          Company of less than substantially all of its assets,  shall, for
          the  purposes  hereof, be deemed to be a liquidation, dissolution
          or winding up of  the  Company.   No holder of Series B Preferred
          Shares  shall be entitled to receive  any  amounts  with  respect
          thereto upon  any  liquidation,  dissolution or winding up of the
          Company other than the amounts provided for herein.

               (6)  PREFERRED RANK.  All shares of Common Stock shall be of
          junior rank to all Series B Preferred  Shares  in  respect to the
          preferences   as   to   distributions   and   payments  upon  the
          liquidation,  dissolution  or  winding  up  of the Company.   The
          rights  of  the shares of Common Stock shall be  subject  to  the
          preferences and relative rights of the Series B Preferred Shares.
          The Series B  Preferred  Shares  shall  be of equal rank with the
          Company's  Series  A Cumulative Convertible  Preferred  Stock  in
          respect  of distributions  and  payments  upon  the  liquidation,
          dissolution  or  winding  up of the Company.  Notwithstanding the
          foregoing, the Company may  authorize  and  issue  additional  or
          other  preferred  stock which is of equal or junior rank with the
          Series B Preferred  Shares  in  respect  of the preferences as to
          distributions and payments upon the liquidation,  dissolution  or
          winding up of the Company; PROVIDED, HOWEVER, that for so long as
          the  Series  B  Preferred  Shares  remain outstanding the Company
          shall not issue any capital stock which  is  more  senior in rank
          than  the  Series B Preferred Shares in respect of the  foregoing
          preferences.  In  the event of the merger or consolidation of the
          Company with or into  another corporation, the Series B Preferred
          Shares shall maintain their  relative  powers,  designations  and
          preferences provided for herein.

               (7)  VOTE  TO CHANGE THE TERMS OF SERIES B PREFERRED SHARES.
          The affirmative vote at a meeting duly called for such purpose or
          the written consent  without a meeting of the holders of not less
          than two-thirds (2/3)  of the then outstanding Series B Preferred
          Shares shall be required to amend, alter, change or repeal any of
          the powers, designations,  preferences and rights of the Series B
          Preferred Shares.

     WARRANT  TO  PURCHASE  364,963 SHARES OF COMMON STOCK VOID AFTER  5:00
P.M. NEW JERSEY TIME, ON FEBRUARY  7, 2001.  THIS WARRANT AND THE SHARES OF
COMMON STOCK ISSUABLE UPON THE EXERCISE HEREOF HAVE BEEN AND WILL BE ISSUED
IN TRANSACTIONS WHICH HAVE NOT BEEN  REGISTERED UNDER THE SECURITIES ACT OF
1933, AS AMENDED (THE "ACT"), OR UNDER  ANY  STATE  SECURITIES  OR BLUE SKY
LAWS.  THIS WARRANT AND SUCH SHARES MAY NOT BE SOLD, TRANSFERRED,  PLEDGED,
HYPOTHECATED  OR OTHERWISE DISPOSED OF, IN WHOLE OR IN PART, IN THE ABSENCE
OF AN EFFECTIVE  REGISTRATION  STATEMENT UNDER THE ACT AND APPLICABLE STATE
LAW,  OR  AN  OPINION  OF  COUNSEL ACCEPTABLE  TO  THE  COMPANY  THAT  SUCH
REGISTRATION IS NOT REQUIRED.


NO. ______1_________                               364,963 SHARES


                            ENZON, INC.

     This certifies that, for  value received, GFL Advantage Fund Ltd., the
registered holder hereof, or assigns  (the  "WARRANTHOLDER") is entitled to
purchase from Enzon, Inc., a Delaware corporation  (the  "COMPANY"), at any
time on and after the earlier of the date the Registration Statement (filed
with the Securities and Exchange Commission (the "SEC") pursuant to Section
2(a)  of a certain Registration Rights Agreement of even date  herewith  by
and among  the  parties hereto) is declared effective by the SEC or seventy
(70) days from the  date  of issuance of this Warrant and before 5:00 p.m.,
New Jersey time, on February  7,  2001  (the  "TERMINATION  DATE"),  at the
purchase  price  of  $4.11  per share (the "EXERCISE PRICE"), the number of
shares of Common Stock, par value  $.01  per share (the "COMMON STOCK"), of
the Company set forth above (the "WARRANT  STOCK"); PROVIDED, HOWEVER, that
in  no event shall the Warrantholder be entitled  to  exercise this Warrant
if, after giving effect to such exercise, the number of  shares  of  Common
Stock  beneficially  owned  by  the  Warrantholder and all other holders of
Common Stock whose holdings would be aggregated  with the Warrantholder for
purposes  of calculating beneficial ownership in accordance  with  Sections
13(d) and 16  of  the  Securities Exchange Act of 1934, as amended, and the
regulations  thereunder  ("SECTIONS   13(D)  AND  16"),  including  without
limitation any person serving as an adviser  to  any  holder (collectively,
the "RELATED PERSONS"), would exceed four and nine-tenths percent (4.9%) of
the  outstanding  shares  of  Common  Stock (calculated in accordance  with
Sections  13(d)  and 16).  The Common Stock  issuable  upon  conversion  of
shares of the Company's  preferred  stock  or  exercise of warrants for the
purchase of Common Stock held by the Warrantholder  or  the Related Persons
shall not be deemed to be beneficially owned by the Warrantholder  or  such
Related  Persons  for this purpose.  The number of shares of Warrant Stock,
the Termination Date and the Exercise Price per share of this Warrant shall
be subject to adjustment from time to time as set forth below.

SECTION I.  TRANSFER OR EXCHANGE OF WARRANT

     The Company shall  be entitled to treat the Warrantholder as the owner
in fact hereof for all purposes  and  shall  not  be bound to recognize any
equitable or other claim to or interest in this Warrant  on the part of any
other person.  This Warrant shall be transferable only on  the books of the
Company, maintained at its principal office, upon delivery of  this Warrant
Certificate  duly  endorsed  by the Warrantholder or by its duly authorized
attorney  or  representative,  or   accompanied   by   proper  evidence  of
succession, assignment or authority to transfer.  Upon any  registration of
transfer,   the  Company  shall  deliver  a  new  Warrant  Certificate   or
Certificates to the persons entitled thereto.

SECTION II.  TERM OF WARRANT; EXERCISE OF WARRANTS

     A.   TERMINATION.  The Company may, in its sole discretion, extend the
Termination Date  with  respect to the exercise of this Warrant upon notice
to the Warrantholder.  As  used  herein, "TERMINATION DATE" shall be deemed
to include any such extensions.

     B.   EXERCISE.  This Warrant  shall  be  exercised by surrender to the
Company,  at  its principal office, of this Warrant  Certificate,  together
with the Purchase  Form attached hereto duly completed and signed, and upon
payment to the Company  of  the  Exercise Price for the number of shares of
Warrant Stock in respect of which  this Warrant is then exercised.  Payment
of the aggregate Exercise Price shall  be  made  in cash or by certified or
official bank check.

     C.   WARRANT CERTIFICATE.  Subject to Section  III  hereof,  upon such
surrender of this Warrant Certificate and payment of the Exercise Price  as
aforesaid, the Company shall issue and cause to be delivered to or upon the
written  order  of  the  Warrantholder,  by  the  second  trading day after
exercise,  a certificate or certificates for the number of full  shares  of
Warrant Stock so purchased upon the exercise of such Warrant, together with
cash, as provided in Section VI hereof, in respect of any fractional shares
of Warrant Stock  otherwise issuable upon such surrender.  Such certificate
or certificates representing the Warrant Stock shall be deemed to have been
issued and any person  so designated to be named therein shall be deemed to
have become a holder of  record  of  such shares of Warrant Stock as of the
date of receipt by the Company of this  Warrant  Certificate and payment of
the Exercise Price as aforesaid; PROVIDED, HOWEVER, that if, at the date of
surrender of this Warrant Certificate and payment  of  the  Exercise Price,
the  transfer  books  for  the  Warrant  Stock  or  other  class  of  stock
purchasable  upon  the  exercise  of  this  Warrant  shall  be  closed, the
certificate  or certificates for the shares of Warrant Stock in respect  of
which this Warrant  is  then  exercised  shall be deemed issuable as of the
date on which such books shall next be opened  (whether before or after the
Termination Date) and until such date the Company shall be under no duty to
deliver any certificate for such shares of Warrant Stock; PROVIDED FURTHER,
HOWEVER, that the transfer books of record, unless  otherwise  required  by
law,  shall  not  be closed at any one time for a period longer than twenty
(20) days.  The rights  of  purchase  represented  by this Warrant shall be
exercisable, at the election of the Warrantholder, either  in  full or from
time  to time in part, and, in the event that this Warrant is exercised  in
respect  of  fewer  than  all of the shares of Warrant Stock purchasable on
such exercise at any time prior  to  the  Termination  Date,  a new Warrant
Certificate  evidencing  the remaining Warrant or Warrants will be  issued,
and the Company shall deliver  the  new Warrant Certificate or Certificates
pursuant to the provisions of this Section.

SECTION III.  PAYMENT OF TAXES

     The Company will pay all documentary stamp taxes, if any, attributable
to the initial issuance of the shares of Warrant Stock upon the exercise of
this Warrant; provided, however, that  the  Warrantholder shall pay any tax
or taxes which may be payable in respect of any  transfer  involved  in the
issue  or  delivery  of  Warrant  Certificates  or the certificates for the
shares of Warrant Stock in a name other than that  of  the Warrantholder in
respect of which this Warrant or shares of Warrant Stock are issued.

SECTION IV.  MUTILATED OR MISSING WARRANT CERTIFICATES

     In case this Warrant Certificate shall be mutilated,  lost,  stolen or
destroyed,  the  Company shall, at the request of the Warrantholder,  issue
and deliver, in exchange and substitution for and upon cancellation of this
certificate if mutilated,  or  in  lieu  of  and  in  substitution for this
certificate if lost, stolen or destroyed, a new Warrant Certificate of like
tenor  and  representing  an equivalent right or interest,  but  only  upon
receipt of evidence reasonably  satisfactory  to  the Company of such loss,
theft  or  destruction  of  this  Warrant  Certificate  and  indemnity,  if
requested, also reasonably satisfactory to the Company.

SECTION V.  RESERVATION OF SHARES OF WARRANT STOCK.

     There  has  been  reserved,  and the Company shall at all  times  keep
reserved so long as this Warrant remains outstanding, out of its authorized
Common Stock a number of shares of  Common  Stock sufficient to provide for
the exercise of the rights of purchase represented  by  this  Warrant.  The
transfer agent for the Common Stock and every subsequent transfer agent for
any  shares  of  the Company's capital stock issuable upon the exercise  of
this Warrant will  be  irrevocably  authorized and directed at all times to
reserve such number of authorized shares  as  shall  be  requisite for such
purpose.

SECTION VI.  FRACTIONAL SHARES.

     No fractional shares or scrip representing fractional  shares shall be
issued upon the exercise of this Warrant.  With respect to any  fraction of
a share called for upon the exercise of this Warrant, the Company shall pay
to the Warrantholder an amount in cash equal to such fraction multiplied by
the Exercise Price then in effect.
SECTION VII.  ADJUSTMENTS OF EXERCISE PRICE AND NUMBER OF SHARES.

     A.   COMPUTATION  OF  ADJUSTED  EXERCISE PRICE.  Except as hereinafter
provided, in case the Company shall at  any  time after the date hereof (i)
issue  or  sell  any  shares  of Common Stock (except  in  those  instances
referred to in subsection F of  this Section VII), including shares held in
the Company's treasury and shares  issued  upon the exercise of any option,
rights  or  warrants  (with the exception of this  Warrant  and  any  other
options,  warrants  and convertible  securities  outstanding  on  the  date
hereof, and without duplicating  any  adjustments  pursuant  to clause (ii)
below) and shares issued upon the direct or indirect conversion or exchange
of  securities  for  shares  of  Common  Stock  (with the exception of  the
Company's  Series A Cumulative Convertible Preferred  Stock  and  Series  B
Convertible  Preferred  Stock  (collectively,  the  "PREFERRED STOCK"), and
without duplicating any adjustments pursuant to clause  (ii)  below)  for a
consideration per share less than the Market Price (as hereinafter defined)
on  the  trading  day  immediately prior to the date of issuance or sale of
such share or without consideration,  or  (ii) issue any rights, options or
warrants  to subscribe for or purchase or otherwise  acquire  Common  Stock
(the "OPTION SECURITIES") or any evidences of indebtedness, shares of stock
or other securities  (other than the Preferred Stock) which are convertible
into or exchangeable,  with or without payment of consideration, for shares
of Common Stock (the "CONVERTIBLE SECURITIES"), whether or not the right to
exercise such Option Securities  or to convert or exchange such Convertible
Securities is immediately exercisable or is conditioned upon the passage of
time, the occurrence or non-occurrence  of some other event, or both, for a
consideration  per  share of Common Stock (calculated  in  accordance  with
subsections A(iii) and  A(iv)  of  this  Article  VII) less than the Market
Price on the trading day immediately prior to the date  of issuance of such
Option  Securities  or  Convertible  Securities, then forthwith  upon  such
issuance or sale the Exercise Price shall  (until  another such issuance or
sale)  be  reduced  to  a  price  (calculated  to  the nearest  full  cent)
determined  by  multiplying the Exercise Price immediately  prior  to  such
issuance or sale  by  a fraction, the numerator of which is an amount equal
to the sum of (X) the total  number  of  shares of Common Stock outstanding
immediately prior to such issuance or sale,  multiplied by the Market Price
in  effect  immediately  prior  to  such issuance or  sale,  plus  (Y)  the
aggregate  of the amount of all consideration,  if  any,  received  by  the
Company upon  such  issuance  or  sale, and the denominator of which is the
Market  Price  in  effect  immediately  prior  to  such  issuance  or  sale
multiplied  by the total number  of  shares  of  Common  Stock  outstanding
immediately after  such  issuance  or  sale;  PROVIDED, HOWEVER, that in no
event shall the Exercise Price be adjusted pursuant  to this computation to
an  amount in excess of the Exercise Price in effect immediately  prior  to
such computation, except in the case of a combination of outstanding shares
of Common Stock, as provided by subsection B of this Section VII.

     For the purposes of any computation to be made in accordance with this
subsection A, the following provisions shall be applicable:

          (i)   In  case  of the issuance or sale of shares of Common Stock
for a consideration part or  all  of which shall be cash, the amount of the
cash consideration therefor shall be  deemed  to  be the amount of the cash
received by the Company for such shares (or, if shares  are  offered by the
Company   for  subscription,  the  subscription  price,  or,  if  sold   to
underwriters  or  dealers  the  public  offering  price)  before  deducting
therefrom   any   compensation  paid  or  discount  allowed  in  the  sale,
underwriting or purchase  thereof  by  underwriters  or  dealers  or others
performing  similar  services,  or  any  expenses  incurred  in  connection
therewith.

          (ii)   In  case  of  the  issuance  or sale (otherwise than as  a
dividend or other distribution on any stock of  the  Company)  of shares of
Common  Stock for a consideration part or all of which shall be other  than
cash, the  amount  of  the  consideration therefor other than cash shall be
deemed to be the value of such consideration as determined in good faith by
the Board of Directors of the Company.

          (iii)In case of the  issuance  of  Convertible  Securities (other
than  the  Convertible  Securities described in (iv) below), the  aggregate
consideration received therefor shall be deemed to be the consideration, if
any,  received  by  the  Company  for  the  issuance  of  such  Convertible
Securities,  plus the additional  minimum  consideration,  if  any,  to  be
received by the Company upon the conversion or exchange thereof.

          (iv)    In  the  case  of  the issuance of Option Securities, the
aggregate  consideration  received therefor  shall  be  deemed  to  be  the
consideration, if any, received  by  the  Company  for the issuance of such
Option Securities, plus the additional minimum consideration, if any, to be
received by the Company upon the exercise thereof.

          (v)  Shares of Common Stock issuable by way  of dividend or other
distribution  on  any  stock of the Company shall be deemed  to  have  been
issued immediately after  the opening of business on the date following the
record date for the determination  of stockholders entitled to receive such
dividend or other distribution and shall  be  deemed  to  have  been issued
without consideration.

          (vi)   The  reclassification of securities of the Company,  other
than shares of Common Stock  into  securities  including  shares  of Common
Stock,  shall  be  deemed  to  involve  the  issuance  of such shares for a
consideration other than cash immediately prior to the close of business on
the  date  fixed  for  the  determination of security holders  entitled  to
receive such shares, and the  value  of the consideration allocable to such
shares  shall  be  determined  as  provided  in  subsection  (ii)  of  this
subsection A.

          (vii)  The number of shares  of  Common  Stock  at  any  one time
outstanding shall include the aggregate number of shares issued or issuable
(subject  to  readjustment  upon  the  actual  issuance  thereof)  upon the
exercise  of  outstanding options, rights, warrants and upon the conversion
or exchange of outstanding convertible or exchangeable securities.

          "MARKET PRICE," as of any date, (i) means the average of the last
reported sale prices for the shares of Common Stock as reported by National
Association of  Securities  Dealers  Automated  Quotation  National  Market
System ("NASDAQ-NMS") for the five consecutive trading days ending on  such
date, or (ii) if the NASDAQ-NMS is not the principal trading market for the
shares of Common Stock, the average of the last reported sale prices on the
principal  trading  market  for the Common Stock during the same period, or
(iii) if market value cannot  be  calculated  as of such date on any of the
foregoing bases, the Market Price shall be the average fair market value as
reasonably  determined  in  good faith by the Board  of  Directors  of  the
Company.

     B.   SUBDIVISION AND COMBINATION.   In  case  the Company shall at any
time  subdivide  or  combine the outstanding shares of  Common  Stock,  the
Exercise Price shall forthwith  be proportionately decreased in the case of
subdivision or increased in case of combination.

     C.   ADJUSTMENT IN NUMBER OF  SHARES.   Upon  each  adjustment  of the
Exercise  Price  pursuant to the provisions of this Section VII, the number
of shares of Warrant Stock issuable upon the exercise of this Warrant shall
be adjusted to the  nearest full share by multiplying a number equal to the
Exercise Price in effect immediately prior to such adjustment by the number
of  shares  of  Warrant  Stock  issuable  upon  exercise  of  this  Warrant
immediately prior  to  such adjustment and dividing the product so obtained
by the adjusted Exercise Price.

     D.   RECLASSIFICATION,  CONSOLIDATION,  MERGER,  ETC.   In case of any
reclassification or change of the outstanding shares of Common Stock (other
than  a  change in par value to no par value, or from no par value  to  par
value, or  as  a result of a subdivision or combination), or in the case of
any consolidation  of  the  Company  with,  or  merger of the Company into,
another  corporation (other than a consolidation or  merger  in  which  the
Company is  the  surviving  corporation  and  which  does not result in any
reclassification  or  change  of  the outstanding shares of  Common  Stock,
except a change as a result of a subdivision  or combination of such shares
or  a change in par value, as aforesaid), or in  the  case  of  a  sale  or
conveyance  to  another  corporation  of  all  or  substantially all of the
property of the Company, the Warrantholder shall thereafter  have the right
to purchase upon the exercise of this Warrant the kind and number of shares
of   stock   and   other  securities  and  property  receivable  upon  such
reclassification, change,  consolidation,  merger, sale or conveyance as if
the Warrantholder were the owner of the shares  of Warrant Stock underlying
this Warrant immediately prior to any such events  at the Exercise Price in
effect  immediately  prior  to  the record date for such  reclassification,
change, consolidation, merger, sale  or conveyance as if such Warrantholder
had exercised this Warrant.

     E.   SPECIAL ADJUSTMENT.  If the  purchase  price  provided for in any
Option Securities, the additional consideration, if any,  payable  upon the
conversion  or exchange of any Convertible Securities or the rate at  which
any Convertible  Securities are convertible into or exchangeable for Common
Stock shall change,  or  if any Option Securities or Convertible Securities
terminate  in  whole  or in part  without  being  exercised,  converted  or
exchanged, the Exercise  Price  in  effect  at the time of such event shall
forthwith be readjusted.  The Exercise Price  shall  be  adjusted  to  that
amount  which  would  have  been  in  effect  at  such time had such Option
Securities  or Convertible Securities outstanding at  such  time  initially
been granted,  issued  or sold and the Exercise Price initially adjusted as
provided in subsection A  of  this  Article  VII,  except  that the minimum
amount of additional consideration payable and the total maximum  number of
shares issuable shall be determined after giving effect to such event  (and
any prior event or events).

     F.   NO  ADJUSTMENT OF EXERCISE PRICE IN CERTAIN CASES.  No adjustment
of the Exercise Price shall be made:

          (i)   Upon  the issuance or sale of this Warrant or the shares of
Warrant Stock issuable  upon  the exercise of this Warrant, or the issuance
or sale of the Preferred Stock,  or  upon  the issuance of shares of Common
Stock in connection with the conversion of such  Preferred  Stock,  or  the
issuance  of  shares  of  Common  Stock  pursuant  to  Section  2(c) of the
Registration  Rights  Agreement  of  even  date  herewith by and among  the
Company and the Buyer and pursuant to Section 2(b)  of  the  Certificate of
Designations,  Preferences  and  Rights  of  Series B Convertible Preferred
Stock of the Company;

          (ii)  Upon the issuance of options,  or  shares upon the exercise
thereof, pursuant to the Company's Non-Qualified Stock  Option Plan, or any
amendment or successor plan thereto;

          (iii)  If the amount of said adjustment shall be  less  than  one
cent  ($.01) per share; provided, however, that in such case any adjustment
that would  otherwise  be required then to be made shall be carried forward
and shall be made at the  time  of  and  together  with  any  adjustment so
carried forward, shall amount to at least one cent ($.01) per Share;

          (iv)   Upon  the  issuance  or sale of shares of Common Stock  or
securities which are exercisable or convertible into shares of Common Stock
to  employees of the Company or its affiliates,  under  an  Employee  Stock
Purchase Plan;

          (v)   Upon  the issuance of any Option Securities or the issuance
of shares of Common Stock  upon  the  exercise  thereof,  where such Option
Security  was  issued for a consideration price per share of  Common  Stock
initially deliverable  upon  exercise  of  such Option Security equal to or
greater than the Market Price in effect immediately  prior  to the issuance
or sale of such Option Security;

          (vi)   Upon  the  issuance  of  Convertible Securities where  the
conversion price is equal to or greater than  the  Market  Price  in effect
immediately prior to the issuance of such Convertible Securities;

          (vii)Upon   the   issuance  of  Common  Stock  to  non-management
directors of the Company in an  amount  up  to  Fourteen  Thousand  Dollars
($14,000)  per  such director per year, based upon such method of valuation
as may be established from time to time by the Company's Board of Directors
in its reasonable discretion; or

          (viii)Upon  the  issuance  of an aggregate of up to Three Million
Dollars ($3,000,000) of Common Stock or securities which are exercisable or
convertible into Common Stock at a discount  to  the Market Price as of the
date of such issuance that does not exceed twenty percent (20%).

SECTION VIII.  NOTICES TO WARRANTHOLDERS.

          WARRANT TO PURCHASE 273,723 SHARES  OF  COMMON  STOCK  VOID AFTER
5:00  P.M.  NEW  JERSEY  TIME,  ON FEBRUARY 7, 2001.  THIS WARRANT AND  THE
SHARES OF COMMON STOCK ISSUABLE UPON THE EXERCISE HEREOF HAVE BEEN AND WILL
BE  ISSUED  IN  TRANSACTIONS  WHICH HAVE  NOT  BEEN  REGISTERED  UNDER  THE
SECURITIES  ACT  OF  1933, AS AMENDED  (THE  "ACT"),  OR  UNDER  ANY  STATE
SECURITIES OR BLUE SKY LAWS.  THIS WARRANT AND SUCH SHARES MAY NOT BE SOLD,
TRANSFERRED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF, IN WHOLE OR IN
PART, IN THE ABSENCE OF  AN  EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT
AND  APPLICABLE STATE LAW, OR AN  OPINION  OF  COUNSEL  ACCEPTABLE  TO  THE
COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED.


NO. _______2________                               273,723 SHARES


                            ENZON, INC.

          This  certifies  that,  for  value received, GFL Performance Fund
Ltd.,  the registered holder hereof, or assigns  (the  "WARRANTHOLDER")  is
entitled  to  purchase  from  Enzon,  Inc.,  a  Delaware  corporation  (the
"COMPANY"),  at  any  time  on  and  after  the  earlier  of  the  date the
Registration  Statement  (filed with the Securities and Exchange Commission
(the "SEC") pursuant to Section  2(a)  of  a  certain  Registration  Rights
Agreement  of  even  date  herewith  by  and  among  the parties hereto) is
declared  effective  by  the  SEC  or seventy (70) days from  the  date  of
issuance of this Warrant and before 5:00 p.m., New Jersey time, on February
7, 2001 (the "TERMINATION DATE"), at  the purchase price of $4.11 per share
(the "EXERCISE PRICE"), the number of shares  of  Common  Stock,  par value
$.01  per  share (the "COMMON STOCK"), of the Company set forth above  (the
"WARRANT  STOCK");   PROVIDED,   HOWEVER,  that  in   no  event  shall  the
Warrantholder be entitled to exercise  this Warrant if, after giving effect
to such exercise, the number of shares of  Common  Stock beneficially owned
by the Warrantholder and all other holders of Common  Stock  whose holdings
would  be  aggregated  with  the  Warrantholder for purposes of calculating
beneficial ownership in accordance  with  Sections  13(d)  and  16  of  the
Securities Exchange Act of 1934, as amended, and the regulations thereunder
("SECTIONS  13(D) AND 16"), including without limitation any person serving
as an adviser  to  any  holder (collectively, the "RELATED PERSONS"), would
exceed four and nine-tenths  percent  (4.9%)  of  the outstanding shares of
Common Stock (calculated in accordance with Sections  13(d)  and  16).  The
Common  Stock issuable upon conversion of shares of the Company's preferred
stock or  exercise of warrants for the purchase of Common Stock held by the
Warrantholder or the Related Persons shall not be deemed to be beneficially
owned by the  Warrantholder  or such Related Persons for this purpose.  The
number of shares of Warrant Stock,  the  Termination  Date and the Exercise
Price per share of this Warrant shall be subject to adjustment from time to
time as set forth below.

SECTION I.  TRANSFER OR EXCHANGE OF WARRANT

          The Company shall be entitled to treat the Warrantholder  as  the
owner  in  fact hereof for all purposes and shall not be bound to recognize
any equitable  or other claim to or interest in this Warrant on the part of
any other person.   This Warrant shall be transferable only on the books of
the Company, maintained  at  its  principal  office,  upon delivery of this
Warrant  Certificate  duly endorsed by the Warrantholder  or  by  its  duly
authorized attorney or representative, or accompanied by proper evidence of
succession, assignment  or authority to transfer.  Upon any registration of
transfer,  the  Company  shall   deliver   a  new  Warrant  Certificate  or
Certificates to the persons entitled thereto.

SECTION II.  TERM OF WARRANT; EXERCISE OF WARRANTS

          A.   TERMINATION.   The  Company may,  in  its  sole  discretion,
extend the Termination Date with respect  to  the  exercise of this Warrant
upon notice to the Warrantholder.  As used herein, "TERMINATION DATE" shall
be deemed to include any such extensions.

          B.   EXERCISE.  This Warrant shall be exercised  by  surrender to
the Company, at its principal office, of this Warrant Certificate, together
with the Purchase Form attached hereto duly completed and signed,  and upon
payment  to  the Company of the Exercise Price for the number of shares  of
Warrant Stock  in respect of which this Warrant is then exercised.  Payment
of the aggregate  Exercise  Price  shall be made in cash or by certified or
official bank check.

          C.   WARRANT CERTIFICATE.   Subject  to  Section III hereof, upon
such  surrender  of this Warrant Certificate and payment  of  the  Exercise
Price as aforesaid, the Company shall issue and cause to be delivered to or
upon the written order  of  the  Warrantholder,  by  the second trading day
after exercise, a certificate or certificates for the number of full shares
of Warrant Stock so purchased upon the exercise of such  Warrant,  together
with  cash,  as provided in Section VI hereof, in respect of any fractional
shares of Warrant  Stock  otherwise  issuable  upon  such  surrender.  Such
certificate or certificates representing the Warrant Stock shall  be deemed
to have been issued and any person so designated to be named therein  shall
be deemed to have become a holder of record of such shares of Warrant Stock
as  of  the  date of receipt by the Company of this Warrant Certificate and
payment of the  Exercise Price as aforesaid; PROVIDED, HOWEVER, that if, at
the date of surrender  of  this  Warrant  Certificate  and  payment  of the
Exercise Price, the transfer books for the Warrant Stock or other class  of
stock  purchasable  upon  the exercise of this Warrant shall be closed, the
certificate or certificates  for  the shares of Warrant Stock in respect of
which this Warrant is then exercised  shall  be  deemed  issuable as of the
date on which such books shall next be opened (whether before  or after the
Termination Date) and until such date the Company shall be under no duty to
deliver any certificate for such shares of Warrant Stock; PROVIDED FURTHER,
HOWEVER,  that  the transfer books of record, unless otherwise required  by
law, shall not be  closed  at  any one time for a period longer than twenty
(20) days.  The rights of purchase  represented  by  this  Warrant shall be
exercisable, at the election of the Warrantholder, either in  full  or from
time  to time in part, and, in the event that this Warrant is exercised  in
respect  of  fewer  than  all of the shares of Warrant Stock purchasable on
such exercise at any time prior  to  the  Termination  Date,  a new Warrant
Certificate  evidencing  the remaining Warrant or Warrants will be  issued,
and the Company shall deliver  the  new Warrant Certificate or Certificates
pursuant to the provisions of this Section.

SECTION III.  PAYMENT OF TAXES

          The  Company  will  pay  all documentary  stamp  taxes,  if  any,
attributable to the initial issuance  of  the  shares of Warrant Stock upon
the  exercise of this Warrant; provided, however,  that  the  Warrantholder
shall  pay any tax or taxes which may be payable in respect of any transfer
involved   in  the  issue  or  delivery  of  Warrant  Certificates  or  the
certificates  for  the shares of Warrant Stock in a name other than that of
the Warrantholder in  respect  of  which  this Warrant or shares of Warrant
Stock are issued.

SECTION IV.  MUTILATED OR MISSING WARRANT CERTIFICATES

          In case this Warrant Certificate shall be mutilated, lost, stolen
or destroyed, the Company shall, at the request of the Warrantholder, issue
and deliver, in exchange and substitution for and upon cancellation of this
certificate  if  mutilated,  or in lieu of and  in  substitution  for  this
certificate if lost, stolen or destroyed, a new Warrant Certificate of like
tenor and representing an equivalent  right  or  interest,  but  only  upon
receipt  of  evidence  reasonably satisfactory to the Company of such loss,
theft  or  destruction  of  this  Warrant  Certificate  and  indemnity,  if
requested, also reasonably satisfactory to the Company.

SECTION V.  RESERVATION OF SHARES OF WARRANT STOCK.

          There has been  reserved, and the Company shall at all times keep
reserved so long as this Warrant remains outstanding, out of its authorized
Common Stock a number of shares  of  Common Stock sufficient to provide for
the exercise of the rights of purchase  represented  by  this Warrant.  The
transfer agent for the Common Stock and every subsequent transfer agent for
any  shares  of the Company's capital stock issuable upon the  exercise  of
this Warrant will  be  irrevocably  authorized and directed at all times to
reserve such number of authorized shares  as  shall  be  requisite for such
purpose.

SECTION VI.  FRACTIONAL SHARES.

          No  fractional  shares  or  scrip representing fractional  shares
shall be issued upon the exercise of this  Warrant.   With  respect  to any
fraction  of  a  share  called  for  upon the exercise of this Warrant, the
Company shall pay to the Warrantholder  an  amount  in  cash  equal to such
fraction multiplied by the Exercise Price then in effect.

SECTION VII.  ADJUSTMENTS OF EXERCISE PRICE AND NUMBER OF SHARES.

          A.   COMPUTATION   OF   ADJUSTED   EXERCISE  PRICE.   Except   as
hereinafter provided, in case the Company shall  at any time after the date
hereof  (i)  issue  or  sell any shares of Common Stock  (except  in  those
instances referred to in  subsection  F  of  this  Section  VII), including
shares held in the Company's treasury and shares issued upon  the  exercise
of  any option, rights or warrants (with the exception of this Warrant  and
any other  options and warrants outstanding on the date hereof, and without
duplicating  any  adjustments  pursuant  to  clause  (ii) below) and shares
issued upon the direct or indirect conversion or exchange of securities for
shares  of  Common  Stock  (with  the exception of the Company's  Series  A
Cumulative Convertible Preferred Stock  and  Series B Convertible Preferred
Stock (collectively, the "PREFERRED STOCK"), and  without  duplicating  any
adjustments  pursuant  to  clause (ii) below) for a consideration per share
less than the Market Price (as  hereinafter  defined)  on  the  trading day
immediately prior to the date of issuance or sale of such share or  without
consideration,  or  (ii) issue any rights, options or warrants to subscribe
for or purchase or otherwise acquire Common Stock (the "OPTION SECURITIES")
or any evidences of indebtedness,  shares  of  stock  or  other  securities
(other   than   the   Preferred   Stock)  which  are  convertible  into  or
exchangeable,  with or without payment  of  consideration,  for  shares  of
Common Stock (the  "CONVERTIBLE  SECURITIES"),  whether or not the right to
exercise such Option Securities or to convert or  exchange such Convertible
Securities is immediately exercisable or is conditioned upon the passage of
time, the occurrence or non-occurrence of some other  event, or both, for a
consideration  per  share  of Common Stock (calculated in  accordance  with
subsections A(iii) and A(iv)  of  this  Article  VII)  less than the Market
Price on the trading day immediately prior to the date of  issuance of such
Option  Securities  or  Convertible  Securities, then forthwith  upon  such
issuance or sale the Exercise Price shall  (until  another such issuance or
sale)  be  reduced  to  a  price  (calculated  to  the nearest  full  cent)
determined  by  multiplying the Exercise Price immediately  prior  to  such
issuance or sale  by  a fraction, the numerator of which is an amount equal
to the sum of (X) the total  number  of  shares of Common Stock outstanding
immediately prior to such issuance or sale,  multiplied by the Market Price
in  effect  immediately  prior  to  such issuance or  sale,  plus  (Y)  the
aggregate  of the amount of all consideration,  if  any,  received  by  the
Company upon  such  issuance  or  sale, and the denominator of which is the
Market  Price  in  effect  immediately  prior  to  such  issuance  or  sale
multiplied  by the total number  of  shares  of  Common  Stock  outstanding
immediately after  such  issuance  or  sale;  PROVIDED, HOWEVER, that in no
event shall the Exercise Price be adjusted pursuant  to this computation to
an  amount in excess of the Exercise Price in effect immediately  prior  to
such computation, except in the case of a combination of outstanding shares
of Common Stock, as provided by subsection B of this Section VII.

          For the purposes of any computation to be made in accordance with
this subsection A, the following provisions shall be applicable:

               (i)   In  case  of  the issuance or sale of shares of Common
Stock for a consideration part or all of which shall be cash, the amount of
the cash consideration therefor shall  be  deemed  to  be the amount of the
cash received by the Company for such shares (or, if shares  are offered by
the  Company  for  subscription,  the  subscription  price, or, if sold  to
underwriters  or  dealers  the  public  offering  price)  before  deducting
therefrom   any  compensation  paid  or  discount  allowed  in  the   sale,
underwriting  or  purchase  thereof  by  underwriters  or dealers or others
performing  similar  services,  or  any  expenses  incurred  in  connection
therewith.

               (ii)  In case of the issuance or sale (otherwise  than  as a
dividend  or  other  distribution on any stock of the Company) of shares of
Common Stock for a consideration  part  or all of which shall be other than
cash, the amount of the consideration therefor  other  than  cash  shall be
deemed to be the value of such consideration as determined in good faith by
the Board of Directors of the Company.

               (iii)In  case  of  the  issuance  of  Convertible Securities
(other  than  the  Convertible  Securities  described in (iv)  below),  the
aggregate  consideration  received  therefor shall  be  deemed  to  be  the
consideration, if any, received by the  Company  for  the  issuance of such
Convertible Securities, plus the additional minimum consideration,  if any,
to be received by the Company upon the conversion or exchange thereof.

               (iv)   In the case of the issuance of Option Securities, the
aggregate  consideration  received  therefor  shall  be  deemed  to  be the
consideration,  if  any,  received  by the Company for the issuance of such
Option Securities, plus the additional minimum consideration, if any, to be
received by the Company upon the exercise thereof.

               (v)  Shares of Common  Stock  issuable by way of dividend or
other distribution on any stock of the Company shall be deemed to have been
issued immediately after the opening of business  on the date following the
record date for the determination of stockholders entitled  to receive such
dividend  or  other  distribution  and shall be deemed to have been  issued
without consideration.

               (vi)  The reclassification  of  securities  of  the Company,
other  than  shares  of  Common  Stock into securities including shares  of
Common Stock, shall be deemed to involve  the issuance of such shares for a
consideration other than cash immediately prior to the close of business on
the  date  fixed  for  the determination of security  holders  entitled  to
receive such shares, and  the  value of the consideration allocable to such
shares  shall  be  determined  as  provided  in  subsection  (ii)  of  this
subsection A.

               (vii)  The number of  shares of Common Stock at any one time
outstanding shall include the aggregate number of shares issued or issuable
(subject  to  readjustment  upon  the actual  issuance  thereof)  upon  the
exercise of outstanding options, rights,  warrants  and upon the conversion
or exchange of outstanding convertible or exchangeable securities.

               "MARKET PRICE," as of any date, (i) means the average of the
last  reported sale prices for the shares of Common Stock  as  reported  by
National  Association  of  Securities  Dealers Automated Quotation National
Market System ("NASDAQ-NMS") for the five  consecutive  trading days ending
on such date, or (ii) if the NASDAQ-NMS is not the principal trading market
for  the  shares  of  Common  Stock, the average of the last reported  sale
prices on the principal trading market for the Common Stock during the same
period, or (iii) if market value  cannot  be  calculated as of such date on
any  of the foregoing bases, the Market Price shall  be  the  average  fair
market  value  as  reasonably  determined  in  good  faith  by the Board of
Directors of the Company.

          B.   SUBDIVISION AND COMBINATION.  In case the Company  shall  at
any  time  subdivide or combine the outstanding shares of Common Stock, the
Exercise Price  shall forthwith be proportionately decreased in the case of
subdivision or increased in case of combination.

          C.   ADJUSTMENT IN NUMBER OF SHARES.  Upon each adjustment of the
Exercise Price pursuant  to  the provisions of this Section VII, the number
of shares of Warrant Stock issuable upon the exercise of this Warrant shall
be adjusted to the nearest full  share by multiplying a number equal to the
Exercise Price in effect immediately prior to such adjustment by the number
of  shares  of  Warrant  Stock  issuable  upon  exercise  of  this  Warrant
immediately prior to such adjustment  and  dividing the product so obtained
by the adjusted Exercise Price.

          D.   RECLASSIFICATION, CONSOLIDATION,  MERGER,  ETC.   In case of
any  reclassification  or change of the outstanding shares of Common  Stock
(other than a change in  par value to no par value, or from no par value to
par value, or as a result  of a subdivision or combination), or in the case
of any consolidation of the  Company  with,  or merger of the Company into,
another corporation (other than a consolidation  or  merger  in  which  the
Company  is  the  surviving  corporation  and  which does not result in any
reclassification  or  change  of the outstanding shares  of  Common  Stock,
except a change as a result of  a subdivision or combination of such shares
or a change in par value, as aforesaid),  or  in  the  case  of  a  sale or
conveyance  to  another  corporation  of  all  or  substantially all of the
property of the Company, the Warrantholder shall thereafter  have the right
to purchase upon the exercise of this Warrant the kind and number of shares
of   stock   and   other  securities  and  property  receivable  upon  such
reclassification, change,  consolidation,  merger, sale or conveyance as if
the Warrantholder were the owner of the shares  of Warrant Stock underlying
this Warrant immediately prior to any such events  at the Exercise Price in
effect  immediately  prior  to  the record date for such  reclassification,
change, consolidation, merger, sale  or conveyance as if such Warrantholder
had exercised this Warrant.

          E.   SPECIAL ADJUSTMENT.  If  the  purchase price provided for in
any Option Securities, the additional consideration,  if  any, payable upon
the  conversion or exchange of any Convertible Securities or  the  rate  at
which  any  Convertible Securities are convertible into or exchangeable for
Common Stock  shall  change,  or  if  any  Option Securities or Convertible
Securities terminate in whole or in part without being exercised, converted
or exchanged, the Exercise Price in effect at  the time of such event shall
forthwith  be readjusted.  The Exercise Price shall  be  adjusted  to  that
amount which  would  have  been  in  effect  at  such  time had such Option
Securities  or  Convertible Securities outstanding at such  time  initially
been granted, issued  or  sold and the Exercise Price initially adjusted as
provided in subsection A of  this  Article  VII,  except  that  the minimum
amount of additional consideration payable and the total maximum  number of
shares issuable shall be determined after giving effect to such event  (and
any prior event or events).

          F.   NO  ADJUSTMENT  OF  EXERCISE  PRICE  IN  CERTAIN  CASES.  No
adjustment of the Exercise Price shall be made:

               (i)  Upon the issuance or sale of this Warrant or the shares
of  Warrant  Stock  issuable  upon  the  exercise  of  this Warrant, or the
issuance or sale of the Preferred Stock, or upon the issuance  of shares of
Common Stock in connection with the conversion of such Preferred  Stock, or

OPTIONS, WARRANTS, SCRIPS, RIGHTS TO SUBSCRIBE TO SHARES OF CAPITAL STOCK

     As of January 26, 1996, there were  outstanding  options  to  purchase
3,863,475  shares  of  the Company's common stock, $.01 par value per share
(the "Common Stock"), of  which (i) 3,663,475 were reserved for issuance at
January 26, 1996 pursuant to  the Company's Non-Qualified Stock Option Plan
and (ii) 200,000 were issued to  Abraham Abuchowski, the Company's Chairman
of the Board, pursuant to an employment agreement.

     As  of  January  26, 1996, there  were  109,000  shares  of  Series  A
Cumulative Convertible  Preferred Stock (the "Series A Preferred Stock") of
the Company outstanding which  are  convertible  into  an aggregate 247,727
shares of Common Stock.

     As  of  January 26, 1996, there were 150,000 warrants  outstanding  to
purchase 150,000 shares of Common Stock at $2.50 per share.  These warrants
expire on August 8, 2000.

     On January  15,  1996,  the  Board  of  Directors  approved  a plan to
compensate  non-employee  directors  which  would  compensate  them with  a
retainer of $2,500 per quarter and $500 per Board meeting payable in shares
of Common Stock at the market price of the Common Stock computed  as of the
first  trading  date of the year in which the compensation is earned.   The
final authorization  of  such  compensation  plan is contingent both on the
draft of such plan by Company counsel and its ratification by the Board and
approval by the shareholders.

REGISTRATION RIGHTS

SCHERING CORPORATION - STOCK PURCHASE AGREEMENT

     This Stock Purchase Agreement contains provisions  for both demand and
"piggy-back" registration rights for 847,489 shares of Common  Stock.   The
demand  registration  rights  provide  generally  for  the  right, upon the
request of 25% of the holders' of the shares of common stock  sold pursuant
to the Stock Purchase Agreement (the "Common Stock") for a period beginning
six   months   after  closing  of  the  agreement  and  continuing  without
limitation, which includes shares of Common Stock issued or issuable by way
of  a  stock  split,  or  in  connection  with  a  combination  of  shares,
reclassification,    recapitalization,    merger    or   consolidation   or
reorganization, the right to have such shares included  in  a  registration
statement  to be filed with the Securities and Exchange Commission.   After
receiving such  request,  the Company must notify the holders of all shares
of Common Stock covered by  the Stock Purchase Agreement, that such holders
may include the shares of Common  Stock  held  by them in such registration
statement if they make a written request to that  effect  within  20  days.
Should  the holders demanding registration of their shares intend to pursue
an underwritten  offering,  the holders of shares entitled to notice of the
intended registration shall also  be  entitled  to  notice  of the intended
underwriting.  Inclusion of any shares in such underwriting is  subject  to
the  discretion  of  the underwriter.  Any reduction of shares made by such
underwriter shall be made  first  out  of  the  shares of holders of either
securities seeking inclusion in such underwriting  and  subsequently out of
the  shares  of the holders of the Common Stock.  Any reduction  of  shares
included in such  underwriting  shall be made pro rata among the holders of
the Common Stock requesting inclusion of their shares.

     The  "piggy-back"  registration  rights  provided  for  in  the  Stock
Purchase Agreement give the  holders  of  the  Common  Stock  the  right to
include  such  shares  in  a  registration  statement  to be filed with the
Commission   for   an   unlimited  period  of  time.   Upon  the  Company's
determination to file such  a  registration  statement, the stockholders of
the Common Stock must receive written notice, after which such holders have
the  right  to respond within 20 days and request  the  inclusion  of  such
shares in the  registration  statement.   The  Company covenants to use its
best efforts to cause such registration statement  to become effective.  In
the  event of an underwritten offering, the holder of  shares  entitled  to
notice  pursuant  to  such  "piggy-back"  rights  shall be advised that the
offering is being underwritten.  Should the underwriter determine, however,
that  the  inclusion  of  certain Common Shares or other  securities,  will
render the Offering unmarketable,  then those shares may be excluded except
for shares being issued by the Company  in a public offering.  Such reduced
number of shares shall be effected pro rata  among  such  security holders.
In the event of such underwritten offering, the holders of  such  shares of
Common  Stock must agree to distribute such shares through such underwriter
and sign an underwriting agreement with such underwriter.

     The  Stock  Purchase  Agreement  also specifically provides that, upon
receipt of the request of any holder of  Common  Stock  acquired  under the
Agreement that such holder's shares be registered on Form S-3, the  Company
shall provide written notice of the proposed registration to all holders of
such Common Stock, and as soon as practicable within 15 days of receipt  of
notice  by such Common Stock holders, include such shares in a registration
statement.   If  the Company has filed an S-3 Registration Statement during
the previous 12 months,  such  request  may  be  denied.  This provision is
separate from the demand registration rights outlined  above.  All expenses
of such registration or registrations will be borne by the Company.

WARRANT AGREEMENT WITH EDWARD S. GORDON & CO. DATED AUGUST 9, 1995

     This  Warrant  Agreement  provides  for  both demand and  "piggy-back"
registration rights with respect to 112,500 shares  of  Common  Stock.  The
Warrant Agreement provides that if the Company receives the written request
by the Warrant holder to prepare and file a registration statement covering
the  shares  issuable  upon exercise of the Warrant (the "Warrant Shares"),
that the Company will use  its  best  efforts  to  prepare  and  file  such
registration  statement  and  keep  it  effective for at least nine months.
Such  demand  registration  rights  shall  be   effective   only   for  the
registration  of more than 50,000 Warrant Shares, provided that in reaching
that threshold,  any  Warrant Shares included by the Pyne Companies, a firm
affiliated with the Warrant  holder,  shall  count towards that amount.  In
the event of an underwritten offering in which  the Warrant holder requests
inclusion, the underwriter has the discretion to  deny  inclusion  of  such
Warrant  Shares  or  other securities, except for shares for which Schering
Corporation requests inclusion.   The  Warrant  Shares  and  shares held by
Schering  should  be  reduced  on  a  pro  rata  basis.  The denial of  the
inclusion  of  Warrant  Shares  as shares held by Schering  of  which  will
require the "lock-up" of such Warrant Shares for a period of 120 days.

     The Warrant Agreement provides  for  "piggy-back"  registration rights
whereby if the Company prepares to file a registration statement  during  a
period of five years and ninety days, other than one on Form S-4, S-8 or S-
1  (for  an  employee stock option plan), the Warrant holder is entitled to
notice of the planned registration and has 20 days to respond to the notice
and request the  inclusion  of  their  Warrant  Shares  in the registration
statement.   If the registration statement will be prepared  and  filed  in
connection with  an  underwritten offering, such underwriter has discretion
over the inclusion of  such  Warrant  Shares  or  other  securities  in the
offering  and  may  thereby  exclude  such  shares  from  the  registration
statement, except that any shares requested to be included in the  offering
by  Schering  Corporation in connection with its demand registration rights
shall have priority over any of the Warrant Shares.  Such reduced number of
shares shall be  allocated  pro rata among Warrant Share holders or holders
of  other  securities requesting  inclusion  of  shares  in  the  offering.
Finally, should  the Company decide to use Form S-3 for registration of any
Warrant Shares and  if  necessary  to effect such registration, the Company
may  require the Warrant holder to exercise  its  Warrant  as  a  condition
precedent  to  the  inclusion of such shares in the registration statement.
All of the expenses of  such registration or registrations will be borne by
the Company.

WARRANT AGREEMENT WITH THE PYNE COMPANIES DATED AUGUST 9, 1995

     This Warrant Agreement  provides  for  only  "piggy-back" registration
rights with respect to 37,500 shares of Common Stock.   Holders of Warrants
under  the  Warrant Agreement have the right to register shares  of  Common
Stock issuable  upon  exercise  of  Warrants  (the "Warrant Shares") if the
Company prepares to file a registration statement  during  a period of five
years  and  ninety  days  other  than one on Form S-4, S-8 or S-1  (for  an
employee  stock  option  plan).   If  the   Company   plans  to  file  such
registration statement, the Warrant holder is entitled  to  notice  of  the
planned  registration  and has 20 days to respond to the notice and request
the inclusion of their Warrant  Shares  in  the registration statement.  If
the  registration  is  part of a public offering,  the  Warrant  holder  is
entitled to notice of the  same.   If  the  registration  statement will be
prepared  and  filed  in  connection  with  an underwritten offering,  such
underwriter has discretion over the inclusion  of  such  Warrant  Shares or
other  securities  in  the offering and may thereby exclude any such shares
from the registration statement,  except  that  any  shares requested to be
included  in  the offering by Schering Corporation in connection  with  its
demand registration  rights  or  shares  to  be  issued by the Company in a
public offering shall have priority over any of the  Warrant  Shares.  Such
reduced  number  of shares shall be allocated pro rata among Warrant  Share
holders or holders  of  other  securities requesting inclusion of shares in
the offering.  Finally, should the  Company  decide  to  use  Form  S-3 for
registration  of  any  Warrant  Shares  and  if  necessary  to  effect such
registration,  the  Company may require the Warrant holder to exercise  its
Warrant as a condition  precedent  to  the  inclusion of such shares in the
registration  statement.   All  of the expenses  of  such  registration  or
registrations will be borne by the Company.

PENDING OR THREATENED LITIGATION

     The Company currently has no  pending  litigation.  There are a number
of matters which the Company has determined to  disclose  pursuant  to this
Stock  Purchase Agreement and related documents, as matters which have  the
potential to give rise to litigation in the future.

NEOPROBE/ENZON,   AUGUST  15,  1992  LICENSE  AGREEMENT  AND  "SCA  PROTEIN
DEVELOPMENT" AGREEMENT.

     This matter involves  a  dispute  over  sums  of money due the Company
pursuant  to  an  agreement between the Company and Neoprobe,  whereby  the
Company agreed to supply  a  certain  amount of research grade single chain
antigen  protein  to Neoprobe and granted  Neoprobe  a  license  under  the
Company's SCA patents.   Under the agreements, Neoprobe was required to pay
Enzon by delivery of either a $400,000 interest-bearing note or warrants to
purchase 100,000 shares of Neoprobe common stock exercisable at 105% of the
initial public offering price  of Neoprobe common stock or $4.00 per share,
and 200,000 shares exercisable at  $10.00  per share.  The parties disagree
over  whether  the  samples  provided by the Company  to  Neoprobe  satisfy
contractual requirements, whether  Enzon is entitled to recover a sum equal
to the amount of the note or exercise  of  the  warrants, and whether Enzon
has breached the Agreements so as not to be entitled  to either the note or
warrants.  To date no litigation has been commenced in this matter.

PATENTS

     The   Company   is   aware  of  certain  issued  patents  and   patent
applications, and there may  be  other patents and applications, containing
subject matter which the Company or  its  licensees  or  collaborators  may
require in order to research, develop or commercialize at least some of the
Company's  products.   There  can  be no assurance that licenses under such
subject matter will be available on  acceptable  terms.  In particular, the
Company is aware of the following:

BIOPURE: US PATENT 5,084,558

     In 1992, the Company received correspondence  from  a  member  of  the
Board  of  Directors  of  Biopure  Corporation  which could be construed as
containing allegations that Biopure's patent for  bovine  hemoglobin  would
cover  the  Company's  PEG-Hemoglobin  products.   On  March  17, 1992, the
Company  obtained  an  opinion  of counsel from the firm of Lerner,  David,
Littenburg, Krumholtz, & Mentlik,  to  the  effect  that the Company's PEG-
Hemoglobin does not infringe any claim of such patent  which  would be held
valid if litigated.  However, there can be no assurance that a  court would
find any of the claims of such patent to be invalid, that a court would not
hold  that the Company's PEG-Hemoglobin product does infringe one  or  more
valid claims of such patent, or that a license could be obtained under such
patent  on acceptable terms.  In October, 1995 Biopure's patent was revoked
by the relevant patent authority of the European Communities.

OXIS U.S. PATENT 5,468,478.

     In  October,   1995,   the   Company   received  a  letter  from  Oxis
International,  Inc.  (formerly  known  as  "DDI  Pharmaceuticals,   Inc.")
advising  that Claim 10 of this Oxis patent for PEG-Protein conjugates  may
be relevant  to  PEG-protein  conjugates  with  PEG  of  a less than 20,000
daltons.   This  claim  recites  water-soluble  polyalkylene  glycol  (PEG)
protein  conjugates in which there are no molecular weight limitations  for
the PEG.   The  original Claim 10 was presented for examination to the U.S.
Patent Office with  a  limitation  requiring  the  PEG  to have a molecular
weight  between  approximately  35,000  to  200,000.   This limitation  was
removed by Oxis during the course of its patent prosecution without comment
by the Examiner.  The patent was issued to Oxis without  reference  to  the
molecular  weight of the PEG.  On January 24, 1996, the Company received an
opinion from  the  law  firm  of Steinberg, Raskin & Davidson to the effect
that  Claim  10 of the Oxis patent,  when  properly  interpreted  would  be
limited  by  a  U.S.   Federal   District   Court  judge  to  water-soluble
polyalkylene  glycol conjugates wherein the PEG  portion  has  a  molecular
weight greater  than  that  contemplated  by  Enzon  for  its  formulations
currently in clinical trials and contemplated for commercialization.

AJINOMOTO, U.S. PATENT 4,301,144.

     Ajinomoto,  a Japanese corporation, received a patent on November  17,
1991 which applies  to  the combination of PEG and Hemoglobin and which was
originally scheduled to expire  on  November 17, 1998.  In view of the GATT
treaty, the Company sought the opinion  of  patent  counsel Learner, David,
Littenburg,  Krumholtz,  &  Mentlik  to evaluate any extension  thereunder.
Such patent has been extended under the  GATT  Treaty  until July 10, 2000.
Additionally, depending on the filing with the FDA for any product approval
by the patentee, or its licensees, the patent could be extended  to as late
as November 17, 2003.  Nonetheless, this extension until 2003 would  depend
upon the patentee or its licensee filing a PLA or NDA prior to November 17,
1998.   The  Company  does  not  expect  that it will have a PEG-Hemoglobin
product approved before the end of 2000, and  thus  would not conflict with
the patent held by Ajinomoto.  Also, although the Company  understands that
a  licensee  of  Ajinomoto has been conducting clinical trials  of  a  PEG-
hemoglobin product  since  July,  1995, the Company believes it is unlikely
that an NDA or PLA can be filed for this product by November 17, 1998.





                   REGISTRATION RIGHTS AGREEMENT

     REGISTRATION RIGHTS AGREEMENT  (this "AGREEMENT"), dated as of January
31,  1996  by  and  among  ENZON,  INC.,  a   Delaware   corporation,  with
headquarters  located  at 20 Kingsbridge Road, Piscataway, NJ   08854  (the

     WHEREAS:

     A.   In connection with the Securities Purchase Agreement by and among
the parties of even date  herewith  (the  "SECURITIES PURCHASE AGREEMENT"),
the Company has agreed, upon the terms and subject to the conditions of the
Securities Purchase Agreement, (i) to issue  and  sell  to the Buyer shares
(the "COMMON SHARES") of the Company's common stock (the  "COMMON  STOCK"),
(ii)  to  issue  and  sell  to  the  Buyer shares of the Company's Series B
Convertible  Preferred  Stock  (the  "PREFERRED   SHARES")  which  will  be
convertible  into  shares  of Common Stock (as converted,  the  "CONVERSION
SHARES"), and (iii) to issue to the Buyer warrants (the "WARRANTS") for the
purchase of shares of Common  Stock  (as  exercised, the "WARRANT SHARES");
and

     B.   To  induce  the  Buyer  to  execute and  deliver  the  Securities
Purchase Agreement, the Company has agreed  to provide certain registration
rights  under the Securities Act of 1933, as amended,  and  the  rules  and
regulations thereunder, or any similar successor statute (collectively, the
"1933 ACT"), and applicable state securities laws;

     NOW,  THEREFORE,  in  consideration  of  the  premises  and the mutual
covenants  contained herein and other good and valuable consideration,  the
receipt and  sufficiency  of which are hereby acknowledged, the Company and
the Buyer hereby agree as follows:

     1.   DEFINITIONS.

          a.   As used in this  Agreement,  the  following terms shall have
the following meanings:

               (i)  "INVESTOR"  means  the  Buyer  and  any  transferee  or
assignee who agrees to become bound by the provisions  of this Agreement in
accordance with Section 9 hereof.

               (ii) "REGISTER," "REGISTERED," and "REGISTRATION" refer to a
registration effected by preparing and filing a Registration  Statement  or
Statements  in  compliance with the 1933 Act and pursuant to Rule 415 under
the 1933 Act or any  successor  rule providing for offering securities on a
continuous  basis  ("RULE  415"),  and   the  declaration  or  ordering  of
effectiveness  of  such  Registration  Statement   by   the  United  States
Securities and Exchange Commission (the "SEC").

               (iii)"REGISTRABLE SECURITIES" means the Common  Shares,  the
Conversion  Shares,  the  Warrant Shares, and the Damage Shares (as defined
below).
               (iv) "REGISTRATION STATEMENT" means a registration statement
of the Company under the 1933 Act.

          b.   Capitalized  terms  used  herein  and  not otherwise defined
herein  shall  have  the  respective meanings set forth in  the  Securities
Purchase Agreement.

     2.   REGISTRATION.

          a.   MANDATORY REGISTRATION.   The Company shall prepare, and, on
or prior to the date which is thirty (30) days after February 7, 1996, file
with the SEC a Registration Statement on Form  S-3  covering  the resale of
the Registrable Securities, which Registration Statement shall  state that,
in   accordance  with  Rule  416  promulgated  under  the  1933  Act,  such
Registration  Statement also covers such indeterminate number of additional
shares of Common  Stock  as  may  become  issuable  upon  conversion of the
Preferred Shares and exercise of the Warrants to prevent dilution resulting
from   stock   splits,  stock  dividends  or  similar  transactions.    The
Registration Statement  (and each amendment or supplement thereto, and each
request for acceleration of effectiveness thereof) shall be provided to and
approved  by the Buyer and  its  counsel  prior  to  its  filing  or  other
submission.

          b.   UNDERWRITTEN  OFFERING.   If  any  offering  pursuant  to  a
Registration   Statement  pursuant  to  Section  2(a)  hereof  involves  an
underwritten offering, the Investors who hold a majority in interest of the
Registrable Securities subject to such underwritten offering shall have the
right to select  one  legal counsel and an investment banker or bankers and
manager or managers to  administer the offering, which investment banker or
bankers or manager or managers  shall  be  reasonably  satisfactory  to the
Company.

          c.   PAYMENTS  BY  THE  COMPANY.   If  the Registration Statement
covering the Registrable Securities required to be  filed  by  the  Company
pursuant to Section 2(a) hereof is not declared effective by the SEC by May
7, 1996 or if, after the Registration Statement has been declared effective
by the SEC, sales cannot be made pursuant to the Registration Statement (by
reason  of  stop  order,  the  Company's failure to update the Registration
Statement or otherwise), or if the  Common  Stock is not listed or included
for quotation on the National Association of  Securities  Dealers Automated
Quotation (the "NASDAQ") National Market System (the "NASDAQ-NMS"), the New
York Stock Exchange (the "NYSE"), the American Stock Exchange  (the "AMEX")
or  the  NASDAQ SmallCap Market ("NASDAQ SMALLCAP"), then the Company  will
make payments  to  the Investors in such amounts and at such times as shall
be determined pursuant  to  this  Section  2(c)  as  partial relief for the
damages  to the Investors by reason of any such delay in  or  reduction  of
their ability to sell the Registrable Securities (which remedy shall not be
exclusive  of any other remedies available at law or in equity, except that
such remedy shall be the exclusive remedy for delay in the effectiveness of
the Registration  Statement  provided  that  the  Registration Statement is
declared effective by the SEC within 180 days after February 7, 1996).  The
Company shall pay to each holder of Registerable Securities an amount equal
to the Average Market Price (as defined below) of the  Common Shares during
the five (5) consecutive trading days ending one (1) trading  day  prior to
the  Closing  Date (the "CLOSING DATE AVERAGE MARKET PRICE") multiplied  by
three-hundredths (.03) times the sum of: (i) the number of months (prorated
for  partial  months)  after  May  7,  1996  and  prior  to  the  date  the
Registration Statement is declared effective by the SEC, provided, however,
that there shall  be  excluded  from such period (and from any period under
clause (ii) immediately below) delays  which  are  attributable  to changes
required by the Investors in the Registration Statement, including, without
limitation, changes to the plan of distribution; (ii) the number of  months
(prorated  for  partial  months)  that sales cannot be made pursuant to the
Registration Statement after the Registration  Statement  has been declared
effective;  and  (iii)  the number of months (prorated for partial  months)
that the Common Stock is  not  listed  or  included  for  quotation  on the
NASDAQ-NMS,  NYSE, AMEX or NASDAQ SmallCap after the Registration Statement
has been declared  effective;  provided that the aggregate number of months
for which payments shall be made  pursuant  to  clauses (i), (ii) and (iii)
above  shall  not exceed twelve (12).  (For example,  if  the  Registration
Statement becomes  effective  one and one-half (1 1/2 ) months after May 7,
1996, the Company would pay $45,000  for  each  $1,000,000  of Closing Date
Average Market Price until any subsequent adjustment; if thereafter,  sales
could  not  be  made pursuant to the Registration Statement for a period of
two (2) months, the  Company  would  pay  an  additional  $60,000  for each
$1,000,000 of Closing Date Average Market Price.)  Such amounts may be paid
at the Company's option in cash or Common Stock (the "DAMAGE SHARES," which
term  shall  include shares of Common Stock that may be issued pursuant  to
Section 2(b) of the Certificate of Designation) valued based on the Average
Market Price for  the  period  (a  "DAMAGE  PRICING  PERIOD")  of  five (5)
consecutive  trading days ending on the trading day prior to the date  that
the Registration  Statement  is  declared  effective  or  that sales can be
resumed under the Registration Statement, as applicable; any amounts due as
to any Damage Pricing Period during which the Registration  Securities  are
not  listed  or  included  for  quotation  on the NASDAQ-NMS, NYSE, AMEX or
NASDAQ SmallCap shall be paid in cash only;  PROVIDED,  HOWEVER, that in no
event shall Damage Shares be paid hereunder if, after giving effect to such
payment,  the  number of shares of Common Stock purchased pursuant  to  the
Securities Purchase  Agreement  or  issued  on  exercise of the Warrants or
conversion of the Preferred Shares and beneficially  owned  by  such holder
and  all other holders whose holdings would be aggregated with such  holder
for  purposes  of  calculating  beneficial  ownership  in  accordance  with
Sections  13(d)  and 16 of the Securities Exchange Act of 1934, as amended,
and  the regulations  thereunder  ("SECTIONS  13(D)  AND  16"),  including,
without  limitation,  any  person  serving  as  an  adviser  to  any holder
(collectively,  the  "RELATED  PERSONS"), would exceed four and nine-tenths
percent  (4.9%)  of  outstanding shares  of  Common  Stock  (calculated  in
accordance with Sections  13(d)  and 16); cash shall be paid for any Damage
Shares  which  cannot be issued pursuant  to  this  proviso.  Common  Stock
issuable upon conversion  of  the  Preferred Shares or exercise of Warrants
held  by such holder or the Related Persons  shall  not  be  deemed  to  be
beneficially  owned by such holder or the Related Persons for this purpose.
Payments of cash  or  issuances  of  Damage Shares pursuant hereto shall be
made within five (5) days after the end  of  each period that gives rise to
such obligation, provided that, if any such period  extends  for  more than
thirty (30) days, interim payments shall be made for each such thirty  (30)
day period with the interim payment (if paid in Damage Shares) based on the
last five (5) trading days of such thirty (30) day period.  In addition  to
the  payments  provided  herein, the Company shall provide an adjustment to
the Conversion Percentage  (as  that  term is defined in the Certificate of
Designation)  and  pay  the  amounts  specified  in  Section  2(b)  of  the
Certificate of Designation.  "AVERAGE MARKET PRICE" of any security for any
period  shall be computed as the arithmetic  average  of  the  closing  bid
prices for such security for each trading day in such period on the NASDAQ-
NMS, or,  if  the  NASDAQ-NMS  is not the principal trading market for such
security, on the principal trading  market for such security, or, if market
value cannot be calculated for such period  on  any of the foregoing bases,
the Average Market Price shall be the average fair market value during such
period as reasonably determined in good faith by  the Board of Directors of
the Company.

          d.   PIGGY-BACK  REGISTRATIONS.   If at any  time  prior  to  the
expiration of the Registration Period (as hereinafter  defined) the Company
shall file with the SEC a Registration Statement relating  to  an  offering
for  its own account or the account of others under the 1933 Act of any  of
its equity  securities  (other  than  on Form S-4 or Form S-8 or their then
equivalents relating to equity securities to be issued solely in connection
with  any  acquisition  of  any  entity or business  or  equity  securities
issuable in connection with stock  option  or other employee benefit plans)
the Company shall send to each Investor who  is  entitled  to  registration
rights under this Section 2(d) written notice of such determination and, if
within  twenty (20) days after receipt of such notice, such Investor  shall
so request  in  writing,  the  Company  shall  include in such Registration
Statement  all  or  any  part of the Registrable Securities  such  Investor
requests  to  be  registered,  except  that  if,  in  connection  with  any
underwritten public  offering  for  the account of the Company the managing
underwriter(s) thereof shall impose a limitation on the number of shares of
Common Stock which may be included in  the  Registration Statement because,
in such underwriter(s)' judgment, marketing or  other  factors dictate that
such  limitation is necessary to facilitate public distribution,  then  the
Company  shall  be obligated to include in such Registration Statement only
such limited portion  of  the  Registrable Securities with respect to which
such Investor has requested inclusion  hereunder;  PROVIDED that no portion
of the equity securities which the Company is offering  for its own account
shall be excluded; PROVIDED, FURTHER that the Company shall  be entitled to
exclude  Registrable Securities to the extent necessary to avoid  breaching
obligations  existing  prior to the date hereof to other securityholders of
the Company.  Any exclusion  of  Registrable  Securities  shall be made pro
rata  among  the  Investors  seeking to include Registrable Securities,  in
proportion to the number of Registrable Securities sought to be included by
such Investors; PROVIDED, HOWEVER,  that  the Company shall not exclude any
Registrable  Securities  unless  the  Company  has   first   excluded   all
outstanding  securities, the holders of which are not entitled to inclusion
of such securities  in  such  Registration Statement or are not entitled to
pro rata inclusion with the Registrable  Securities; and PROVIDED, FURTHER,
HOWEVER, that, after giving effect to the  immediately  preceding  proviso,
any exclusion of Registrable Securities shall be made pro rata with holders
of  other  securities  having  the  right to include such securities in the
Registration  Statement  other  than  holders  of  securities  entitled  to
inclusion of their securities in such Registration  Statement  by reason of
demand  registration  rights.   No  right  to  registration  of Registrable
Securities  under  this  Section  2(d)  shall  be  construed  to limit  any
registration  required under Section 2(a) hereof.  The obligations  of  the
Company under this  Section  2(d)  may  be  waived  by  Investors holding a
majority  in  interest  of the Registrable Securities.  If an  offering  in
connection with which any  Investor  is entitled to registration under this
Section  2(d)  is  an  underwritten  offering,  then  each  Investor  whose
Registrable Securities are included in  such  Registration Statement shall,
unless  otherwise agreed by the Company, offer and  sell  such  Registrable
Securities  in  an  underwritten  offering  using  the  same underwriter or
underwriters and, subject to the provisions of this Agreement,  on the same
terms  and  conditions  as  other  shares of Common Stock included in  such
underwritten offering.

          e.   ELIGIBILITY  FOR  FORM  S-3.   The  Company  represents  and
warrants  that it meets the requirements  for  the  use  of  Form  S-3  for
registration  of  the  sale  by  the  Buyer  and  any other Investor of the
Registrable Securities and the Company shall file all  reports  required to
be  filed by the Company with the SEC in a timely manner so as to  maintain
such  eligibility  for  the use of Form S-3.  In the event that Form S-3 is
not available for the sale  by the Investors of the Registrable Securities,
the Company shall register the sale on another appropriate form.

     3.   OBLIGATIONS OF THE COMPANY.

     In connection with the registration of the Registrable Securities, the
Company shall have the following obligations:

          a.   The Company shall  prepare  promptly,  and file with the SEC
not  later  than  thirty (30) days after February 7, 1996,  a  Registration
Statement with respect  to the number of Registrable Securities provided in
Section  2(a), and thereafter  to  use  its  best  efforts  to  cause  each
Registration   Statement  relating  to  Registrable  Securities  to  become
effective as soon  as possible after such filing, and keep the Registration
Statement effective pursuant to Rule 415 at all times until such date as is
the  earlier of (i) at  least  three  (3)  years  after  the  date  of  the
expiration  of  all  the Warrants, or (ii) the date on which (a) all of the
Warrants have been exercised  or expired, (b) no Registrable Securities are
held by any Investor, and (c) none  of  the Preferred Shares is outstanding
(the "REGISTRATION PERIOD"), which Registration  Statement  (including  any
amendments or supplements thereto and prospectuses contained therein) shall
not  contain  any  untrue  statement  of a material fact or omit to state a
material  fact required to be stated therein,  or  necessary  to  make  the
statements  therein, in light of the circumstances in which they were made,
not misleading.

          b.   The  Company  shall  prepare  and  file  with  the  SEC such
amendments  (including  post-effective  amendments) and supplements to  the
Registration  Statement and the prospectus  used  in  connection  with  the
Registration Statement  as  may  be  necessary  to  keep  the  Registration
Statement  effective  at  all  times  during the Registration Period,  and,
during such period, comply with the provisions of the 1933 Act with respect
to the disposition of all Registrable Securities  of the Company covered by
the  Registration  Statement  until  such time as all of  such  Registrable
Securities have been disposed of in accordance with the intended methods of
disposition  by  the  seller  or  sellers  thereof  as  set  forth  in  the
Registration Statement.

          c.   The Company shall furnish to each Investor whose Registrable
Securities are included in the Registration Statement and its legal counsel
(i)  promptly after the same is prepared and  publicly  distributed,  filed
with the  SEC,  or  received  by  the Company, one copy of the Registration
Statement  and  any  amendment thereto,  each  preliminary  prospectus  and
prospectus and each amendment  or  supplement  thereto, and, in the case of
the Registration Statement referred to in Section 2(a), each letter written
by or on behalf of the Company to the SEC or the staff of the SEC, and each
item of correspondence from the SEC or the staff  of  the SEC, in each case
relating  to  such Registration Statement (other than any  portion  of  any
thereof  which contains  information  for  which  the  Company  has  sought
confidential  treatment),  and  (ii) such number of copies of a prospectus,
including a preliminary prospectus,  and  all  amendments  and  supplements
thereto and such other documents as such Investor may reasonably request in
order to facilitate the disposition of the Registrable Securities  owned by
such Investor.

          d.   The Company shall use reasonable efforts to (i) register and
qualify  the  Registrable  Securities covered by the Registration Statement
under such other securities or "blue sky" laws of such jurisdictions in the
United States as the Investors  who  hold  a  majority  in  interest of the
Registrable Securities being offered reasonably request, (ii)  prepare  and
file  in  those  jurisdictions  such  amendments  (including post-effective
amendments) and supplements to such registrations and qualifications as may
be necessary to maintain the effectiveness thereof  during the Registration
Period, (iii) take such other actions as may be necessary  to maintain such
registrations  and  qualifications  in  effect  at  all  times  during  the
Registration  Period,  and (iv) take all other actions reasonably necessary
or  advisable to qualify  the  Registrable  Securities  for  sale  in  such
jurisdictions; PROVIDED, HOWEVER, that the Company shall not be required in
connection  therewith  or  as  a  condition  thereto  to  (a) qualify to do
business  in any jurisdiction where it would not otherwise be  required  to
qualify but  for  this Section 3(d), (b) subject itself to general taxation
in any such jurisdiction,  (c) file a general consent to service of process
in any such jurisdiction, (d) provide any undertakings that cause more than
nominal expense or burden to  the  Company,  or  (e) make any change in its
charter or bylaws, which in each case the Board of Directors of the Company
determines  to be contrary to the best interests of  the  Company  and  its
stockholders.

          e.   In  the  event  Investors who hold a majority in interest of
the  Registrable  Securities  being   offered   in   the   offering  select
underwriters for the offering, the Company shall enter into and perform its
obligations  under an underwriting agreement, in usual and customary  form,
including, without  limitation,  customary indemnification and contribution
obligations, with the underwriters of such offering.  The incremental costs
incident  to  such  an  underwritten  offering   shall   be   paid  by  the
participating  Investors  pro  rata  based  on  the  number  of Registrable
Securities sold by them.

          f.   As  promptly  as  practicable after becoming aware  of  such
event, the Company shall notify each  Investor  of  the  happening  of  any
event,  of  which  the  Company  has  knowledge,  as  a result of which the
prospectus  included  in  the  Registration Statement, as then  in  effect,
includes an untrue statement of  a  material  fact  or  omission to state a
material  fact  required  to  be stated therein or necessary  to  make  the
statements therein, in light of  the  circumstances  under  which they were
made,  not  misleading,  and  use  its  best efforts promptly to prepare  a
supplement  or  amendment to the Registration  Statement  to  correct  such
untrue statement  or  omission,  and  deliver such number of copies of such
supplement or amendment to each Investor  as  such  Investor may reasonably
request.

          g.   The  Company  shall  use  its best efforts  to  prevent  the
issuance  of  any  stop order or other suspension  of  effectiveness  of  a
Registration Statement,  and,  if  such  an  order is issued, to obtain the
withdrawal of such order at the earliest possible moment and to notify each
Investor who holds Registrable Securities being  sold  (or, in the event of
an  underwritten offering, the managing underwriters) of  the  issuance  of
such order and the resolution thereof.

          h.   The   Company   shall  permit  a  single  firm  of  counsel,
designated as selling stockholders'  counsel  by  the  Investors who hold a
majority in interest of the Registrable Securities being  sold,  to  review
the  Registration  Statement  and all amendments and supplements thereto  a
reasonable period of time prior  to their filing with the SEC, and not file
any document in a form to which such counsel reasonably objects.

          i.   The Company shall make  generally  available to its security
holders as soon as practical, but not later than ninety (90) days after the
close  of  the  period  covered  thereby,  an earnings statement  (in  form
complying with the provisions of Rule 158 under  the  1933  Act) covering a
twelve-month period beginning not later than the first day of the Company's
fiscal  quarter  next  following  the  effective  date  of the Registration
Statement.

          j.   At  the  request  of  the Investors who hold a  majority  in
interest  of  the Registrable Securities  being  sold,  the  Company  shall
furnish, on the  date  that  Registrable  Securities  are  delivered  to an
underwriter, if any, for sale in connection with the Registration Statement
(i)  if  required  by  an  underwriter, a letter, dated such date, from the
Company's independent certified public accountants in form and substance as
is  customarily  given  by  independent  certified  public  accountants  to
underwriters  in  an  underwritten   public   offering,  addressed  to  the
underwriters,  and (ii) an opinion, dated as of  such  date,  from  counsel
representing the  Company  for  purposes of such Registration Statement, in
form, scope and substance as is customarily given in an underwritten public
offering, addressed to the underwriters and the Investors.

          k.   The Company shall  make  available for inspection by (i) any
Investor, (ii) any underwriter participating in any disposition pursuant to
the Registration Statement, (iii) one firm  of  attorneys  and  one firm of
accountants  or  other  agents  retained  by  the  Buyer, (iv) one firm  of
attorneys and one firm of accountants or other agents retained by all other
Investors, and (v) one firm of attorneys retained by  all such underwriters
(collectively, the "INSPECTORS") all pertinent financial and other records,
and   pertinent   corporate   documents  and  properties  of  the   Company
(collectively, the "RECORDS"),  as  shall be reasonably deemed necessary by
each  Inspector to enable each Inspector  to  exercise  its  due  diligence
responsibility,  and  cause the Company's officers, directors and employees
to supply all information  which  any  Inspector may reasonably request for
purposes  of such due diligence; PROVIDED,  HOWEVER,  that  each  Inspector
shall hold  in  confidence  and shall not make any disclosure (except to an
Investor) of any Record or other  information  which the Company determines
in good faith to be confidential, and of which determination the Inspectors
are so notified, unless (a) the disclosure of such  Records is necessary to
avoid or correct a misstatement or omission in any Registration  Statement,
(b) the release of such Records is ordered pursuant to a subpoena  or other
order from a court or government body of competent jurisdiction, or (c) the
information in such Records has been made generally available to the public
other than by disclosure in violation of this or any other agreement.   The
Company  shall  not be required to disclose any confidential information in
such Records to any  Inspector  until  and unless such Inspector shall have
entered into confidentiality agreements (in form and substance satisfactory
to the Company) with the Company with respect thereto, substantially in the
form  of  this Section 3(k).  Each Investor  agrees  that  it  shall,  upon
learning that  disclosure  of  such  Records  is sought in or by a court or
governmental body of competent jurisdiction or  through  other  means, give
prompt  notice  to  the  Company and allow the Company, at its expense,  to
undertake appropriate action  to  prevent  disclosure  of,  or  to obtain a
protective order for, the Records deemed confidential.

          l.   The  Company  shall  hold  in  confidence  and not make  any
disclosure  of information concerning an Investor provided to  the  Company
hereof unless  (i)  disclosure  of  such information is necessary to comply
with  federal  or  state  securities laws,  (ii)  the  disclosure  of  such
information is necessary to  avoid or correct a misstatement or omission in
any  Registration Statement, (iii)  the  release  of  such  information  is
ordered  pursuant to a subpoena or other order from a court or governmental
body of competent  jurisdiction,  or  (iv)  such  information has been made
generally available to the public other than by disclosure  in violation of
this  or  any  other  agreement.   The  Company agrees that it shall,  upon
learning  that disclosure of such information  concerning  an  Investor  is
sought in or  by  a court or governmental body of competent jurisdiction or
through other means,  give  prompt  notice  to such Investor, and allow the
Investor,  at  its  expense,  to undertake appropriate  action  to  prevent
disclosure of, or to obtain a protective order for, such information.

          m.   The Company shall  use  its best efforts either to (i) cause
all the Registrable Securities covered by  the Registration Statement to be
listed on a national securities exchange and  on  each  additional national
securities exchange on which securities of the same class  or series issued
by the Company are then listed, if any, if the listing of such  Registrable
Securities  is  then  permitted  under the rules of such exchange, or  (ii)
secure designation and quotation of  all the Registrable Securities covered
by  the  Registration  Statement  on the NASDAQ-NMS  or,  if,  despite  the
Company's best efforts to satisfy the  preceding  clause  (i)  or (ii), the
Company is unsuccessful in satisfying the preceding clause (i) or  (ii), to
secure  the  inclusion  for  quotation  on  the  NASDAQ  SmallCap  for such
Registrable   Securities  and,  without  limiting  the  generality  of  the
foregoing, to arrange  for  at least two market makers to register with the
National Association of Securities  Dealers,  Inc.  ("NASD")  as  such with
respect to such Registrable Securities.  The Investors' sole remedy for the
Company's  failure  to  perform  under  this  Section  shall be as provided
Section 2(c) hereof and in Section 2(b) of the Certificate of Designation.

          n.   The  Company shall provide a transfer agent  and  registrar,
which may be a single entity, for the Registrable Securities not later than
the effective date of the Registration Statement.
          o.   The Company  shall  cooperate  with  the  Investors who hold
Registrable  Securities  being  offered  and  the  managing underwriter  or
underwriters, if any, to facilitate the timely preparation  and delivery of
certificates representing Registrable Securities to be offered  pursuant to
the  Registration  Statement  and  enable  such certificates to be in  such
denominations or amounts, as the case may be,  as  the managing underwriter
or  underwriters,  if  any,  or  the Investors may reasonably  request  and
registered in such names as the managing  underwriter  or  underwriters, if
any, or the Investors may request.  No later than the effective date of any
Registration  Statement  registering the resale of Registrable  Securities,
the Company shall deliver  to  its transfer agent instructions, accompanied
by any reasonably required opinion  of  counsel,  that  (i) permit sales of
legended  securities in a timely fashion that complies with  then  mandated
securities  settlement  procedures for regular way market transactions; and
(ii) upon the exercise of  Warrants  or  conversion of Preferred Shares and
the   contemporaneous  resale,  pursuant  to  an   effective   Registration
Statement,  of  the applicable Warrant Shares and Conversion Shares, permit
the issuance of stock  certificates  without  restrictive  legends  to  the
transferees of such Warrant Shares and Conversion Shares.

          p.   The   Company   shall  take  all  other  reasonable  actions
necessary  to  expedite and facilitate  disposition  by  the  Investors  of
Registrable Securities pursuant to the Registration Statement.

     4.   OBLIGATIONS OF THE INVESTORS.

     In connection with the registration of the Registrable Securities, the
Investors shall have the following obligations:

          a.   It  shall be a condition precedent to the obligations of the
Company to complete  the  registration  pursuant  to  this  Agreement  with
respect  to  the  Registrable Securities of a particular Investor that such
Investor shall furnish  to  the  Company such information regarding itself,
the  Registrable  Securities  held  by   it  and  the  intended  method  of
disposition of the Registrable Securities held by it as shall be reasonably
required  to  effect the registration of such  Registrable  Securities  and
shall execute such  documents  in  connection with such registration as the
Company may reasonably request.  At  least five (5) days prior to the first
anticipated filing date of the Registration  Statement,  the  Company shall
notify each investor of the information the Company requires from each such
Investor if such Investor elects to have any of such Investor's Registrable
Securities included in the Registration Statement.

          b.   Each   Investor   by   such  Investor's  acceptance  of  the
Registrable Securities agrees to cooperate  with  the Company as reasonably
requested by the Company in connection with the preparation  and  filing of
the Registration Statement hereunder, unless such Investor has notified the
Company  in  writing  of  such  Investor's  election to exclude all of such
Investor's Registrable Securities from the Registration Statement.

          c.   In the event Investors holding a majority in interest of the
Registrable Securities being registered determine to engage the services of
an  underwriter,  each  Investor  agrees to enter  into  and  perform  such
Investor's  obligations  under  an underwriting  agreement,  in  usual  and
customary form, including, without  limitation,  customary  indemnification
and  contribution  obligations,  with  the  managing  underwriter  of  such
offering and take such other actions as are reasonably required in order to
expedite  or  facilitate  the  disposition  of  the Registrable Securities,
unless such Investor has notified the Company in writing of such Investor's
election to exclude all of such Investor's Registrable  Securities from the
Registration  Statement.   The  incremental  costs  incident  to   such  an
underwritten  offering shall be paid by the Investor to the extent provided
in Section 3(e).

          d.   Each  Investor  agrees that, upon receipt of any notice from
the Company of the happening of  any event of the kind described in Section
3(f)  or 3(g), such Investor will immediately  discontinue  disposition  of
Registrable Securities pursuant to the Registration Statement covering such
Registrable  Securities  until such Investor's receipt of the copies of the
supplemented or amended prospectus  contemplated  by  Section  3(f) or 3(g)
and,  if  so  directed by the Company, such Investor shall deliver  to  the
Company (at the  expense  of  the  Company)  or destroy (and deliver to the
Company  a  certificate  of  destruction)  all copies  in  such  Investor's
possession, of the prospectus covering such  Registrable Securities current
at the time of receipt of such notice.

          e.   No Investor may participate in any underwritten registration
hereunder  unless  such  Investor  (i)  agrees  to  sell   such  Investor's
Registrable   Securities   on   the  basis  provided  in  any  underwriting
arrangements approved by the Investors  entitled  hereunder to approve such
arrangements,  (ii)  completes and executes all questionnaires,  powers  of
attorney,  indemnities,   underwriting   agreements   and  other  documents
reasonably required under the terms of such underwriting  arrangements, and
(iii)  agrees to pay its pro rata share of all underwriting  discounts  and
commissions.

     5.   EXPENSES OF REGISTRATION.

     All   reasonable  expenses,  other  than  underwriting  discounts  and
commissions,   incurred   in  connection  with  registrations,  filings  or
qualifications pursuant to Sections 2 and 3, including, without limitation,
all registration, listing and  qualifications fees, printers and accounting
fees, the fees and disbursements  of  counsel for the Company, and the fees
and disbursements of one (1) firm of counsel  for  the  Investors, shall be
borne by the Company.

      6.  INDEMNIFICATION.

     In the event any Registrable Securities are included in a Registration
Statement under this Agreement:

          a.   To the extent permitted by law, the Company  will indemnify,
hold  harmless  and  defend  (i)  each  Investor who holds such Registrable
Securities, (ii) the directors, officers  and  each person who controls any
Investor within the meaning of the 1933 Act or the  Securities Exchange Act
of 1934, as amended (the "1934 ACT"), if any, and (iii) any underwriter (as
defined in the 1933 Act) for the Investors; and the directors, officers and
each person who controls any such underwriter within  the  meaning  of  the
1933  Act or the 1934 Act, if any, (each, an "INDEMNIFIED PERSON"), against
any losses,  claims,  damages,  liabilities  or expenses (joint or several)
(collectively, "CLAIMS") to which any of them may become subject insofar as
such Claims (or actions or proceedings, whether commenced or threatened, in
respect thereof) arise out of or are based upon:  (i)  any untrue statement
or alleged untrue statement of a material fact in a Registration  Statement
or  the  omission  or  alleged  omission  to  state therein a material fact
required  to  be  stated or necessary to make the  statements  therein  not
misleading, (ii) any  untrue  statement  or  alleged  untrue statement of a
material fact contained in any preliminary prospectus if  used prior to the
effective date of such Registration Statement, or contained  in  the  final
prospectus  (as amended or supplemented, if the Company files any amendment
thereof or supplement  thereto  with  the  SEC)  or the omission or alleged
omission  to  state  therein  any  material  fact  necessary  to  make  the
statements  made  therein, in light of the circumstances  under  which  the
statements therein  were  made,  not  misleading, or (iii) any violation or
alleged  violation  relating  to  the offer  or  sale  of  the  Registrable
Securities by the Company of the 1933  Act,  the  1934  Act, any other law,
including, without limitation, any state securities law,  or  any  rule  or
regulation  thereunder  (the  matters  in the foregoing clauses (i) through
(iii) being, collectively, "VIOLATIONS").   Subject to the restrictions set
forth  in Section 6(d) with respect to the number  of  legal  counsel,  the
Company  shall  reimburse  the  Investors  and  each  such  underwriter  or
controlling  person, promptly as such expenses are incurred and are due and
payable,  for any  reasonable  legal  fees  or  other  reasonable  expenses
incurred by  them  in  connection  with investigating or defending any such
Claim, subject to the provisions of Section 6(d).  Notwithstanding anything
to the contrary contained herein, the  indemnification  agreement contained
in  this  Section 6(a): (i) shall not apply to a Claim arising  out  of  or
based upon a Violation which occurs in reliance upon and in conformity with
information  furnished  in writing to the Company by any Indemnified Person
or underwriter for such Indemnified  Person expressly for use in connection
with the preparation of the Registration  Statement  or  any such amendment
thereof or supplement thereto, if such prospectus was timely made available
by the Company pursuant to Section 3(c) hereof; (ii) with  respect  to  any
preliminary  prospectus,  shall not inure to the benefit of any such person
from whom the person asserting  any  such  Claim  purchased the Registrable
Securities that are the subject thereof (or to the  benefit  of  any person
controlling  such  person)  if the untrue statement or omission of material
fact  contained  in  the  preliminary   prospectus  was  corrected  in  the
prospectus, as then amended or supplemented,  if such prospectus was timely
made available by the Company pursuant to Section  3(c) hereof; (iii) shall
not  be available to the extent such Claim is based on  a  failure  of  the
Investor  to  deliver  or  to  cause  to  be  delivered the prospectus made
available  by  the Company; and (iv) shall not apply  to  amounts  paid  in
settlement of any  Claim  if  such settlement is effected without the prior
written consent of the Company,  which  consent  shall  not be unreasonably
withheld.  Such indemnity shall remain in full force and  effect regardless
of  any  investigation made by or on behalf of the Indemnified  Person  and
shall survive  the  transfer of the Registrable Securities by the Investors
pursuant to Section 9.

          b.   In connection  with  any Registration Statement in which any
Investor is participating, each such  Investor  agrees  to  indemnify, hold
harmless and defend, to the same extent and in the same manner set forth in
Section 6(a), the Company, each of its directors, each of its  officers who
signs  the  Registration  Statement, each person, if any, who controls  the
Company within the meaning of the 1933 Act or the 1934 Act, any underwriter
and any other stockholder selling  securities  pursuant to the Registration
Statement or any of its directors or officers or  any  person  who controls
such stockholder or underwriter within the meaning of the 1933 Act  or  the
1934  Act  (collectively  and  together  with  an  indemnified  Person,  an
"INDEMNIFIED  PARTY"),  against  any  Claim to which any of them may become
subject, under the 1933 Act, the 1934 Act  or  otherwise,  insofar  as such
Claim  arises  out  of  or is based upon any Violation, in each case to the
extent (and only to the extent) that such violation occurs in reliance upon
and in conformity with written information furnished to the Company by such
Investor expressly for use  in  connection with such Registration Statement
or to the extent such Claim is based  upon  the  failure of the Investor to
deliver  or  cause  to be delivered the prospectus made  available  by  the
Company; and such Investor  will  reimburse  any  legal  or  other expenses
reasonably  incurred by them in connection with investigating or  defending
any such Claim;  PROVIDED,  HOWEVER, that the indemnity agreement contained
in this Section 6(b) shall not  apply  to amounts paid in settlement of any
Claim if such settlement is effected without  the  prior written consent of
such Investor, which consent shall not be unreasonably  withheld; PROVIDED,
FURTHER, HOWEVER, that the Investor shall be liable under this Section 6(b)
for only that amount of a Claim as does not exceed the net proceeds to such
Investor as a result of the sale of Registrable Securities pursuant to such
Registration  Statement.   Such  indemnity shall remain in full  force  and
effect  regardless of any investigation  made  by  or  on  behalf  of  such
Indemnified  Party  and  shall  survive  the  transfer  of  the Registrable
Securities by the Investors pursuant to Section 9. Notwithstanding anything
to  the contrary contained herein, the indemnification agreement  contained
in this  Section  6(b) with respect to any preliminary prospectus shall not
inure to the benefit  of  any  Indemnified Party if the untrue statement or
omission  of material fact contained  in  the  preliminary  prospectus  was
corrected on  a  timely  basis  in  the  prospectus,  as  then  amended  or
supplemented.

          c.   The  Company  shall  be entitled to receive indemnities from
underwriters,  selling  brokers, dealer  managers  and  similar  securities
industry professionals participating  in  any  distribution,  to  the  same
extent  as  provided  above,  with  respect  to information such persons so
furnished  in  writing  by  such persons expressly  for  inclusion  in  the
Registration Statement.

          d.   Promptly  after   receipt   by   an  Indemnified  Person  or
Indemnified Party under this Section 6 of notice of the commencement of any
action  (including  any governmental action), such  Indemnified  Person  or
Indemnified Party shall,  if  a Claim in respect thereof is to made against
any indemnifying party under this  Section  6,  deliver to the indemnifying
party a written notice of the commencement thereof,  and  the  indemnifying
party  shall  have  the  right  to  participate in, and, to the extent  the
indemnifying party so desires, jointly  with  any  other indemnifying party
similarly noticed, to assume control of the defense  thereof  with  counsel
mutually  satisfactory to the indemnifying party and the Indemnified Person
or the Indemnified  Party,  as  the case may be; PROVIDED, HOWEVER, that an
Indemnified Person or Indemnified  Party shall have the right to retain its
own counsel with the fees and expenses  to  be  paid  by  the  indemnifying
party,   if,   in  the  reasonable  opinion  of  counsel  retained  by  the
indemnifying party,  the  representation by such counsel of the Indemnified
Person  or  Indemnified  Party   and   the   indemnifying  party  would  be
inappropriate due to actual or potential differing  interests  between such
Indemnified Person or Indemnified Party and any other party represented  by
such  counsel  in  such  proceeding.   The  Company  shall pay for only one
separate legal counsel for the Investors, and such legal  counsel  shall be
selected by the Investors holding a majority in interest of the Registrable
Securities  included  in  the  Registration  Statement  to  which the Claim
relates.   The failure to deliver written notice to the indemnifying  party
within a reasonable  time  of the commencement of any such action shall not
relieve such indemnifying party  of any liability to the Indemnified Person
or Indemnified Party under this Section  6,  except  to the extent that the
indemnifying party is prejudiced in its ability to defend such action.  The
indemnification  required  by  this  Section  6 shall be made  by  periodic
payments of the amount thereof during the course  of  the  investigation or
defense, as such expense, loss, damage or liability is incurred  and is due
and payable.

     7.   CONTRIBUTION.

     To  the  extent  any  indemnification  by  an  indemnifying  party  is
prohibited  or  limited  by  law, the indemnifying party agrees to make the
maximum  contribution with respect  to  any  amounts  for  which  it  would
otherwise be liable under Section 6 to the fullest extent permitted by law;
PROVIDED,   HOWEVER,   that   (i)  no  contribution  shall  be  made  under
circumstances   where  the  maker  would   not   have   been   liable   for
indemnification under  the  fault standards set forth in Section 6, (ii) no
seller of Registrable Securities  guilty  of  fraudulent  misrepresentation
(within the meaning of Section 11(f) of the 1933 Act) shall  be entitled to
contribution from any seller of Registrable Securities who was  not  guilty
of  such fraudulent misrepresentation, and (iii) contribution by any seller
of Registrable  Securities  shall be limited in amount to the net amount of
proceeds  received  by  such seller  from  the  sale  of  such  Registrable
Securities.

     8.   REPORTS UNDER THE 1934 ACT.

     With a view to making  available to the Investors the benefits of Rule
144 promulgated under the 1933  Act or any other similar rule or regulation
of the SEC that may at any time permit  the investors to sell securities of
the Company to the public without registration  ("RULE  144"),  the Company
agrees to:

          a.   make  and keep public information available, as those  terms
are understood and defined in Rule 144;

          b.   file with  the  SEC in a timely manner all reports and other
documents required of the Company  under  the 1933 Act and the Exchange Act
so  long  as  the Company remains subject to such  requirements  (it  being
understood that  nothing herein shall limit the Company's obligations under
Section 4(c) of the  Securities  Purchase Agreement) and the filing of such
reports and other documents is required  for  the  applicable provisions of
Rule 144; and

          c.   furnish  to  each  Investor  so long as such  Investor  owns
Registrable Securities, promptly upon request,  (i)  a written statement by
the  Company that it has complied with the reporting requirements  of  Rule
144, the  1933  Act and the 1934 Act, (ii) a copy of the most recent annual
or quarterly report  of the Company and such other reports and documents so
filed by the Company, and (iii) such other information as may be reasonably
requested to permit the  investors to sell such securities pursuant to Rule
144 without registration.

     9.   ASSIGNMENT OF REGISTRATION RIGHTS.

     The  rights  to  have  the  Company  register  Registrable  Securities
pursuant  to  this  Agreement shall  be  automatically  assignable  by  the
Investors to any transferee of all or any portion of Registrable Securities
if: (i) the Investor  agrees  in writing with the transferee or assignee to
assign such rights, and a copy  of  such  agreement  is  furnished  to  the
Company  within  a  reasonable time after such assignment, (ii) the Company
is, within a reasonable  time  after such transfer or assignment, furnished
with written notice of (a) the name  and  address  of  such  transferee  or
assignee,  and  (b)  the securities with respect to which such registration
rights are being transferred  or assigned, (iii) immediately following such
transfer or assignment the further  disposition  of  such securities by the
transferee  or  assignee  is restricted under the 1933 Act  and  applicable
state securities laws, (iv)  at or before the time the Company receives the
written notice contemplated by  clause (ii) of this sentence the transferee
or assignee agrees in writing with  the  Company  to be bound by all of the
provisions  contained herein, (v) such transfer shall  have  been  made  in
accordance with  the  applicable  requirements  of  the Securities Purchase
Agreement,  and (vi) such transferee shall be an "ACCREDITED  INVESTOR"  as
that term defined  in  Rule  501 of Regulation D promulgated under the 1933
Act.

     10.  AMENDMENT OF REGISTRATION RIGHTS.

     Provisions of this Agreement may be amended and the observance thereof
may be waived (either generally  or  in  a  particular  instance and either
retroactively or prospectively), only with written consent  of  the Company
and   Investors  who  hold  a  majority  in  interest  of  the  Registrable
Securities.   Any  amendment  or  waiver  effected  in accordance with this
Section 10 shall be binding upon each Investor and the Company.

     11.  MISCELLANEOUS.

          a.   A person or entity is deemed to be a holder  of  Registrable
Securities  whenever  such person or entity owns of record such Registrable
Securities.  If the Company  receives  conflicting instructions, notices or
elections from two or more persons or entities  with  respect  to  the same
Registrable   Securities,   the   Company  shall  act  upon  the  basis  of
instructions, notice or election received from the registered owner of such
Registrable Securities.

          b.   Notices required or permitted to be given hereunder shall be

if, after giving effect to  such  exercise,  the number of shares of Common
Stock beneficially owned by the Warrantholder  and  all  other  holders  of
Common  Stock whose holdings would be aggregated with the Warrantholder for
purposes  of  calculating  beneficial ownership in accordance with Sections
13(d) and 16 of the Securities  Exchange  Act  of 1934, as amended, and the
regulations  thereunder  ("SECTIONS  13(D)  AND  16"),   including  without
limitation  any  person serving as an adviser to any holder  (collectively,
the "RELATED PERSONS"), would exceed four and nine-tenths percent (4.9%) of
the outstanding shares  of  Common  Stock  (calculated  in  accordance with
Sections  13(d)  and  16).   The  Common Stock issuable upon conversion  of
shares of the Company's preferred stock  or  exercise  of  warrants for the
purchase  of Common Stock held by the Warrantholder or the Related  Persons
shall not be  deemed  to be beneficially owned by the Warrantholder or such
Related Persons for this  purpose.   The number of shares of Warrant Stock,
the Termination Date and the Exercise Price per share of this Warrant shall
be subject to adjustment from time to time as set forth below.
SECTION I.  TRANSFER OR EXCHANGE OF WARRANT

     The Company shall be entitled to  treat the Warrantholder as the owner
in fact hereof for all purposes and shall  not  be  bound  to recognize any
equitable or other claim to or interest in this Warrant on the  part of any
other person.  This Warrant shall be transferable only on the books  of the
Company,  maintained at its principal office, upon delivery of this Warrant
Certificate  duly  endorsed  by the Warrantholder or by its duly authorized
attorney  or  representative,  or   accompanied   by   proper  evidence  of
succession, assignment or authority to transfer.  Upon any  registration of
transfer,   the  Company  shall  deliver  a  new  Warrant  Certificate   or
Certificates to the persons entitled thereto.

SECTION II.  TERM OF WARRANT; EXERCISE OF WARRANTS

     A.   TERMINATION.  The Company may, in its sole discretion, extend the
Termination Date  with  respect to the exercise of this Warrant upon notice
to the Warrantholder.  As  used  herein, "TERMINATION DATE" shall be deemed
to include any such extensions.

     B.   EXERCISE.  This Warrant  shall  be  exercised by surrender to the
Company,  at  its principal office, of this Warrant  Certificate,  together
with the Purchase  Form attached hereto duly completed and signed, and upon
payment to the Company  of  the  Exercise Price for the number of shares of
Warrant Stock in respect of which  this Warrant is then exercised.  Payment
of the aggregate Exercise Price shall  be  made  in cash or by certified or
official bank check.

     C.   WARRANT CERTIFICATE.  Subject to Section  III  hereof,  upon such
surrender of this Warrant Certificate and payment of the Exercise Price  as
aforesaid, the Company shall issue and cause to be delivered to or upon the
written  order  of  the  Warrantholder,  by  the  second  trading day after
exercise,  a certificate or certificates for the number of full  shares  of
Warrant Stock so purchased upon the exercise of such Warrant, together with
cash, as provided in Section VI hereof, in respect of any fractional shares
of Warrant Stock  otherwise issuable upon such surrender.  Such certificate
or certificates representing the Warrant Stock shall be deemed to have been
issued and any person  so designated to be named therein shall be deemed to
have become a holder of  record  of  such shares of Warrant Stock as of the
date of receipt by the Company of this  Warrant  Certificate and payment of
the Exercise Price as aforesaid; PROVIDED, HOWEVER, that if, at the date of
surrender of this Warrant Certificate and payment  of  the  Exercise Price,
the  transfer  books  for  the  Warrant  Stock  or  other  class  of  stock
purchasable  upon  the  exercise  of  this  Warrant  shall  be  closed, the
certificate  or certificates for the shares of Warrant Stock in respect  of
which this Warrant  is  then  exercised  shall be deemed issuable as of the
date on which such books shall next be opened  (whether before or after the
Termination Date) and until such date the Company shall be under no duty to
deliver any certificate for such shares of Warrant Stock; PROVIDED FURTHER,
HOWEVER, that the transfer books of record, unless  otherwise  required  by
law,  shall  not  be closed at any one time for a period longer than twenty
(20) days.  The rights  of  purchase  represented  by this Warrant shall be
exercisable, at the election of the Warrantholder, either  in  full or from
time  to time in part, and, in the event that this Warrant is exercised  in
respect  of  fewer  than  all of the shares of Warrant Stock purchasable on
such exercise at any time prior  to  the  Termination  Date,  a new Warrant
Certificate  evidencing  the remaining Warrant or Warrants will be  issued,
and the Company shall deliver  the  new Warrant Certificate or Certificates
pursuant to the provisions of this Section.

SECTION III.  PAYMENT OF TAXES

     The Company will pay all documentary stamp taxes, if any, attributable
to the initial issuance of the shares of Warrant Stock upon the exercise of
this Warrant; provided, however, that  the  Warrantholder shall pay any tax
or taxes which may be payable in respect of any  transfer  involved  in the
issue  or  delivery  of  Warrant  Certificates  or the certificates for the
shares of Warrant Stock in a name other than that  of  the Warrantholder in
respect of which this Warrant or shares of Warrant Stock are issued.

SECTION IV.  MUTILATED OR MISSING WARRANT CERTIFICATES

     In case this Warrant Certificate shall be mutilated,  lost,  stolen or
destroyed,  the  Company shall, at the request of the Warrantholder,  issue
and deliver, in exchange and substitution for and upon cancellation of this
certificate if mutilated,  or  in  lieu  of  and  in  substitution for this
certificate if lost, stolen or destroyed, a new Warrant Certificate of like
tenor  and  representing  an equivalent right or interest,  but  only  upon
receipt of evidence reasonably  satisfactory  to  the Company of such loss,
theft  or  destruction  of  this  Warrant  Certificate  and  indemnity,  if
requested, also reasonably satisfactory to the Company.

SECTION V.  RESERVATION OF SHARES OF WARRANT STOCK.

     There  has  been  reserved,  and the Company shall at all  times  keep
reserved so long as this Warrant remains outstanding, out of its authorized
Common Stock a number of shares of  Common  Stock sufficient to provide for
the exercise of the rights of purchase represented  by  this  Warrant.  The
transfer agent for the Common Stock and every subsequent transfer agent for
any  shares  of  the Company's capital stock issuable upon the exercise  of
this Warrant will  be  irrevocably  authorized and directed at all times to
reserve such number of authorized shares  as  shall  be  requisite for such
purpose.

SECTION VI.  FRACTIONAL SHARES.

     No fractional shares or scrip representing fractional  shares shall be
issued upon the exercise of this Warrant.  With respect to any  fraction of
a share called for upon the exercise of this Warrant, the Company shall pay
to the Warrantholder an amount in cash equal to such fraction multiplied by
the Exercise Price then in effect.

SECTION VII.  ADJUSTMENTS OF EXERCISE PRICE AND NUMBER OF SHARES.

     A.   COMPUTATION  OF  ADJUSTED  EXERCISE PRICE.  Except as hereinafter
provided, in case the Company shall at  any  time after the date hereof (i)
issue  or  sell  any  shares  of Common Stock (except  in  those  instances
referred to in subsection F of  this Section VII), including shares held in
the Company's treasury and shares  issued  upon the exercise of any option,
rights  or  warrants  (with the exception of this  Warrant  and  any  other
options,  warrants  and convertible  securities  outstanding  on  the  date
hereof, and without duplicating  any  adjustments  pursuant  to clause (ii)
below) and shares issued upon the direct or indirect conversion or exchange
of  securities  for  shares  of  Common  Stock  (with the exception of  the
Company's  Series A Cumulative Convertible Preferred  Stock  and  Series  B
Convertible  Preferred  Stock  (collectively,  the  "PREFERRED STOCK"), and
without duplicating any adjustments pursuant to clause  (ii)  below)  for a
consideration per share less than the Market Price (as hereinafter defined)
on  the  trading  day  immediately prior to the date of issuance or sale of
such share or without consideration,  or  (ii) issue any rights, options or
warrants  to subscribe for or purchase or otherwise  acquire  Common  Stock
(the "OPTION SECURITIES") or any evidences of indebtedness, shares of stock
or other securities  (other than the Preferred Stock) which are convertible
into or exchangeable,  with or without payment of consideration, for shares
of Common Stock (the "CONVERTIBLE SECURITIES"), whether or not the right to
exercise such Option Securities  or to convert or exchange such Convertible
Securities is immediately exercisable or is conditioned upon the passage of
time, the occurrence or non-occurrence  of some other event, or both, for a
consideration  per  share of Common Stock (calculated  in  accordance  with
subsections A(iii) and  A(iv)  of  this  Article  VII) less than the Market
Price on the trading day immediately prior to the date  of issuance of such
Option  Securities  or  Convertible  Securities, then forthwith  upon  such
issuance or sale the Exercise Price shall  (until  another such issuance or
sale)  be  reduced  to  a  price  (calculated  to  the nearest  full  cent)
determined  by  multiplying the Exercise Price immediately  prior  to  such
issuance or sale  by  a fraction, the numerator of which is an amount equal
to the sum of (X) the total  number  of  shares of Common Stock outstanding
immediately prior to such issuance or sale,  multiplied by the Market Price
in  effect  immediately  prior  to  such issuance or  sale,  plus  (Y)  the
aggregate  of the amount of all consideration,  if  any,  received  by  the
Company upon  such  issuance  or  sale, and the denominator of which is the
Market  Price  in  effect  immediately  prior  to  such  issuance  or  sale
multiplied  by the total number  of  shares  of  Common  Stock  outstanding
immediately after  such  issuance  or  sale;  PROVIDED, HOWEVER, that in no
event shall the Exercise Price be adjusted pursuant  to this computation to
an  amount in excess of the Exercise Price in effect immediately  prior  to
such computation, except in the case of a combination of outstanding shares
of Common Stock, as provided by subsection B of this Section VII.

     For the purposes of any computation to be made in accordance with this
subsection A, the following provisions shall be applicable:

          (i)   In  case  of the issuance or sale of shares of Common Stock
for a consideration part or  all  of which shall be cash, the amount of the
cash consideration therefor shall be  deemed  to  be the amount of the cash
received by the Company for such shares (or, if shares  are  offered by the
Company   for  subscription,  the  subscription  price,  or,  if  sold   to
underwriters  or  dealers  the  public  offering  price)  before  deducting
therefrom   any   compensation  paid  or  discount  allowed  in  the  sale,
underwriting or purchase  thereof  by  underwriters  or  dealers  or others
performing  similar  services,  or  any  expenses  incurred  in  connection
therewith.

          (ii)   In  case  of  the  issuance  or sale (otherwise than as  a
dividend or other distribution on any stock of  the  Company)  of shares of
Common  Stock for a consideration part or all of which shall be other  than
cash, the  amount  of  the  consideration therefor other than cash shall be
deemed to be the value of such consideration as determined in good faith by
the Board of Directors of the Company.

          (iii)In case of the  issuance  of  Convertible  Securities (other
than  the  Convertible  Securities described in (iv) below), the  aggregate
consideration received therefor shall be deemed to be the consideration, if
any,  received  by  the  Company  for  the  issuance  of  such  Convertible
Securities,  plus the additional  minimum  consideration,  if  any,  to  be
received by the Company upon the conversion or exchange thereof.

          (iv)    In  the  case  of  the issuance of Option Securities, the
aggregate  consideration  received therefor  shall  be  deemed  to  be  the
consideration, if any, received  by  the  Company  for the issuance of such
Option Securities, plus the additional minimum consideration, if any, to be
received by the Company upon the exercise thereof.

          (v)  Shares of Common Stock issuable by way  of dividend or other
distribution  on  any  stock of the Company shall be deemed  to  have  been
issued immediately after  the opening of business on the date following the
record date for the determination  of stockholders entitled to receive such
dividend or other distribution and shall  be  deemed  to  have  been issued
without consideration.

          (vi)   The  reclassification of securities of the Company,  other
than shares of Common Stock  into  securities  including  shares  of Common
Stock,  shall  be  deemed  to  involve  the  issuance  of such shares for a
consideration other than cash immediately prior to the close of business on
the  date  fixed  for  the  determination of security holders  entitled  to
receive such shares, and the  value  of the consideration allocable to such
shares  shall  be  determined  as  provided  in  subsection  (ii)  of  this
subsection A.

          (vii)  The number of shares  of  Common  Stock  at  any  one time
outstanding shall include the aggregate number of shares issued or issuable
(subject  to  readjustment  upon  the  actual  issuance  thereof)  upon the
exercise  of  outstanding options, rights, warrants and upon the conversion
or exchange of outstanding convertible or exchangeable securities.

          "MARKET PRICE," as of any date, (i) means the average of the last
reported sale prices for the shares of Common Stock as reported by National
Association of  Securities  Dealers  Automated  Quotation  National  Market
System ("NASDAQ-NMS") for the five consecutive trading days ending on  such
date, or (ii) if the NASDAQ-NMS is not the principal trading market for the
shares of Common Stock, the average of the last reported sale prices on the
principal  trading  market  for the Common Stock during the same period, or
(iii) if market value cannot  be  calculated  as of such date on any of the
foregoing bases, the Market Price shall be the average fair market value as
reasonably  determined  in  good faith by the Board  of  Directors  of  the
Company.
     B.   SUBDIVISION AND COMBINATION.   In  case  the Company shall at any
time  subdivide  or  combine the outstanding shares of  Common  Stock,  the
Exercise Price shall forthwith  be proportionately decreased in the case of
subdivision or increased in case of combination.

     C.   ADJUSTMENT IN NUMBER OF  SHARES.   Upon  each  adjustment  of the
Exercise  Price  pursuant to the provisions of this Section VII, the number
of shares of Warrant Stock issuable upon the exercise of this Warrant shall
be adjusted to the  nearest full share by multiplying a number equal to the
Exercise Price in effect immediately prior to such adjustment by the number
of  shares  of  Warrant  Stock  issuable  upon  exercise  of  this  Warrant
immediately prior  to  such adjustment and dividing the product so obtained
by the adjusted Exercise Price.

     D.   RECLASSIFICATION,  CONSOLIDATION,  MERGER,  ETC.   In case of any
reclassification or change of the outstanding shares of Common Stock (other
than  a  change in par value to no par value, or from no par value  to  par
value, or  as  a result of a subdivision or combination), or in the case of
any consolidation  of  the  Company  with,  or  merger of the Company into,
another  corporation (other than a consolidation or  merger  in  which  the
Company is  the  surviving  corporation  and  which  does not result in any
reclassification  or  change  of  the outstanding shares of  Common  Stock,
except a change as a result of a subdivision  or combination of such shares
or  a change in par value, as aforesaid), or in  the  case  of  a  sale  or
conveyance  to  another  corporation  of  all  or  substantially all of the
property of the Company, the Warrantholder shall thereafter  have the right
to purchase upon the exercise of this Warrant the kind and number of shares
of   stock   and   other  securities  and  property  receivable  upon  such
reclassification, change,  consolidation,  merger, sale or conveyance as if
the Warrantholder were the owner of the shares  of Warrant Stock underlying
this Warrant immediately prior to any such events  at the Exercise Price in
effect  immediately  prior  to  the record date for such  reclassification,
change, consolidation, merger, sale  or conveyance as if such Warrantholder
had exercised this Warrant.

     E.   SPECIAL ADJUSTMENT.  If the  purchase  price  provided for in any
Option Securities, the additional consideration, if any,  payable  upon the
conversion  or exchange of any Convertible Securities or the rate at  which
any Convertible  Securities are convertible into or exchangeable for Common
Stock shall change,  or  if any Option Securities or Convertible Securities
terminate  in  whole  or in part  without  being  exercised,  converted  or
exchanged, the Exercise  Price  in  effect  at the time of such event shall
forthwith be readjusted.  The Exercise Price  shall  be  adjusted  to  that
amount  which  would  have  been  in  effect  at  such time had such Option
Securities  or Convertible Securities outstanding at  such  time  initially
been granted,  issued  or sold and the Exercise Price initially adjusted as
provided in subsection A  of  this  Article  VII,  except  that the minimum
amount of additional consideration payable and the total maximum  number of
shares issuable shall be determined after giving effect to such event  (and
any prior event or events).

     F.   NO  ADJUSTMENT OF EXERCISE PRICE IN CERTAIN CASES.  No adjustment
of the Exercise Price shall be made:

          (i)   Upon  the issuance or sale of this Warrant or the shares of
Warrant Stock issuable  upon  the exercise of this Warrant, or the issuance
or sale of the Preferred Stock,  or  upon  the issuance of shares of Common
Stock in connection with the conversion of such  Preferred  Stock,  or  the
issuance  of  shares  of  Common  Stock  pursuant  to  Section  2(c) of the
Registration  Rights  Agreement  of  even  date  herewith by and among  the
Company and the Buyer and pursuant to Section 2(b)  of  the  Certificate of
Designations,  Preferences  and  Rights  of  Series B Convertible Preferred
Stock of the Company;

          (ii)  Upon the issuance of options,  or  shares upon the exercise
thereof, pursuant to the Company's Non-Qualified Stock  Option Plan, or any
amendment or successor plan thereto;

          (iii)  If the amount of said adjustment shall be  less  than  one
cent  ($.01) per share; provided, however, that in such case any adjustment
that would  otherwise  be required then to be made shall be carried forward
and shall be made at the  time  of  and  together  with  any  adjustment so
carried forward, shall amount to at least one cent ($.01) per Share;

          (iv)   Upon  the  issuance  or sale of shares of Common Stock  or
securities which are exercisable or convertible into shares of Common Stock
to  employees of the Company or its affiliates,  under  an  Employee  Stock
Purchase Plan;

          (v)   Upon  the issuance of any Option Securities or the issuance
of shares of Common Stock  upon  the  exercise  thereof,  where such Option
Security  was  issued for a consideration price per share of  Common  Stock
initially deliverable  upon  exercise  of  such Option Security equal to or
greater than the Market Price in effect immediately  prior  to the issuance
or sale of such Option Security;

          (vi)   Upon  the  issuance  of  Convertible Securities where  the
conversion price is equal to or greater than  the  Market  Price  in effect
immediately prior to the issuance of such Convertible Securities;

          (vii)Upon   the   issuance  of  Common  Stock  to  non-management
directors of the Company in an  amount  up  to  Fourteen  Thousand  Dollars
($14,000)  per  such director per year, based upon such method of valuation
as may be established from time to time by the Company's Board of Directors
in its reasonable discretion; or

          (viii)Upon  the  issuance  of an aggregate of up to Three Million
Dollars ($3,000,000) of Common Stock or securities which are exercisable or
convertible into Common Stock at a discount  to  the Market Price as of the
date of such issuance that does not exceed twenty percent (20%).

5:00  P.M.  NEW  JERSEY  TIME,  ON FEBRUARY 7, 2001.  THIS WARRANT AND  THE
SHARES OF COMMON STOCK ISSUABLE UPON THE EXERCISE HEREOF HAVE BEEN AND WILL
BE  ISSUED  IN  TRANSACTIONS  WHICH HAVE  NOT  BEEN  REGISTERED  UNDER  THE
SECURITIES  ACT  OF  1933, AS AMENDED  (THE  "ACT"),  OR  UNDER  ANY  STATE
SECURITIES OR BLUE SKY LAWS.  THIS WARRANT AND SUCH SHARES MAY NOT BE SOLD,
TRANSFERRED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF, IN WHOLE OR IN
PART, IN THE ABSENCE OF  AN  EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT
AND  APPLICABLE STATE LAW, OR AN  OPINION  OF  COUNSEL  ACCEPTABLE  TO  THE

NO. _______2________                               273,723 SHARES


                            ENZON, INC.

          This  certifies  that,  for  value received, GFL Performance Fund
Ltd.,  the registered holder hereof, or assigns  (the  "WARRANTHOLDER")  is
entitled  to  purchase  from  Enzon,  Inc.,  a  Delaware  corporation  (the
"COMPANY"),  at  any  time  on  and  after  the  earlier  of  the  date the
Registration  Statement  (filed with the Securities and Exchange Commission
(the "SEC") pursuant to Section  2(a)  of  a  certain  Registration  Rights
Agreement  of  even  date  herewith  by  and  among  the parties hereto) is
declared  effective  by  the  SEC  or seventy (70) days from  the  date  of
issuance of this Warrant and before 5:00 p.m., New Jersey time, on February
7, 2001 (the "TERMINATION DATE"), at  the purchase price of $4.11 per share
(the "EXERCISE PRICE"), the number of shares  of  Common  Stock,  par value
$.01  per  share (the "COMMON STOCK"), of the Company set forth above  (the
"WARRANT  STOCK");   PROVIDED,   HOWEVER,  that  in   no  event  shall  the
Warrantholder be entitled to exercise  this Warrant if, after giving effect
to such exercise, the number of shares of  Common  Stock beneficially owned
by the Warrantholder and all other holders of Common  Stock  whose holdings
would  be  aggregated  with  the  Warrantholder for purposes of calculating
beneficial ownership in accordance  with  Sections  13(d)  and  16  of  the
Securities Exchange Act of 1934, as amended, and the regulations thereunder
("SECTIONS  13(D) AND 16"), including without limitation any person serving
as an adviser  to  any  holder (collectively, the "RELATED PERSONS"), would
exceed four and nine-tenths  percent  (4.9%)  of  the outstanding shares of
Common Stock (calculated in accordance with Sections  13(d)  and  16).  The
Common  Stock issuable upon conversion of shares of the Company's preferred
stock or  exercise of warrants for the purchase of Common Stock held by the
Warrantholder or the Related Persons shall not be deemed to be beneficially
owned by the  Warrantholder  or such Related Persons for this purpose.  The
number of shares of Warrant Stock,  the  Termination  Date and the Exercise
Price per share of this Warrant shall be subject to adjustment from time to
time as set forth below.

SECTION I.  TRANSFER OR EXCHANGE OF WARRANT

          The Company shall be entitled to treat the Warrantholder  as  the
owner  in  fact hereof for all purposes and shall not be bound to recognize
any equitable  or other claim to or interest in this Warrant on the part of
any other person.   This Warrant shall be transferable only on the books of
the Company, maintained  at  its  principal  office,  upon delivery of this
Warrant  Certificate  duly endorsed by the Warrantholder  or  by  its  duly
authorized attorney or representative, or accompanied by proper evidence of
succession, assignment  or authority to transfer.  Upon any registration of
transfer,  the  Company  shall   deliver   a  new  Warrant  Certificate  or
Certificates to the persons entitled thereto.

SECTION II.  TERM OF WARRANT; EXERCISE OF WARRANTS

          A.   TERMINATION.   The  Company may,  in  its  sole  discretion,
extend the Termination Date with respect  to  the  exercise of this Warrant
upon notice to the Warrantholder.  As used herein, "TERMINATION DATE" shall
be deemed to include any such extensions.

          B.   EXERCISE.  This Warrant shall be exercised  by  surrender to
the Company, at its principal office, of this Warrant Certificate, together
with the Purchase Form attached hereto duly completed and signed,  and upon
payment  to  the Company of the Exercise Price for the number of shares  of
Warrant Stock  in respect of which this Warrant is then exercised.  Payment
of the aggregate  Exercise  Price  shall be made in cash or by certified or
official bank check.

          C.   WARRANT CERTIFICATE.   Subject  to  Section III hereof, upon
such  surrender  of this Warrant Certificate and payment  of  the  Exercise
Price as aforesaid, the Company shall issue and cause to be delivered to or
upon the written order  of  the  Warrantholder,  by  the second trading day
after exercise, a certificate or certificates for the number of full shares
of Warrant Stock so purchased upon the exercise of such  Warrant,  together
with  cash,  as provided in Section VI hereof, in respect of any fractional
shares of Warrant  Stock  otherwise  issuable  upon  such  surrender.  Such
certificate or certificates representing the Warrant Stock shall  be deemed
to have been issued and any person so designated to be named therein  shall
be deemed to have become a holder of record of such shares of Warrant Stock
as  of  the  date of receipt by the Company of this Warrant Certificate and
payment of the  Exercise Price as aforesaid; PROVIDED, HOWEVER, that if, at
the date of surrender  of  this  Warrant  Certificate  and  payment  of the
Exercise Price, the transfer books for the Warrant Stock or other class  of
stock  purchasable  upon  the exercise of this Warrant shall be closed, the
certificate or certificates  for  the shares of Warrant Stock in respect of
which this Warrant is then exercised  shall  be  deemed  issuable as of the
date on which such books shall next be opened (whether before  or after the
Termination Date) and until such date the Company shall be under no duty to
deliver any certificate for such shares of Warrant Stock; PROVIDED FURTHER,
HOWEVER,  that  the transfer books of record, unless otherwise required  by
law, shall not be  closed  at  any one time for a period longer than twenty
(20) days.  The rights of purchase  represented  by  this  Warrant shall be
exercisable, at the election of the Warrantholder, either in  full  or from
time  to time in part, and, in the event that this Warrant is exercised  in
respect  of  fewer  than  all of the shares of Warrant Stock purchasable on
such exercise at any time prior  to  the  Termination  Date,  a new Warrant
Certificate  evidencing  the remaining Warrant or Warrants will be  issued,
and the Company shall deliver  the  new Warrant Certificate or Certificates
pursuant to the provisions of this Section.

SECTION III.  PAYMENT OF TAXES

          The  Company  will  pay  all documentary  stamp  taxes,  if  any,
attributable to the initial issuance  of  the  shares of Warrant Stock upon
the  exercise of this Warrant; provided, however,  that  the  Warrantholder
shall  pay any tax or taxes which may be payable in respect of any transfer
involved   in  the  issue  or  delivery  of  Warrant  Certificates  or  the
certificates  for  the shares of Warrant Stock in a name other than that of
the Warrantholder in  respect  of  which  this Warrant or shares of Warrant
Stock are issued.

SECTION IV.  MUTILATED OR MISSING WARRANT CERTIFICATES

          In case this Warrant Certificate shall be mutilated, lost, stolen
or destroyed, the Company shall, at the request of the Warrantholder, issue
and deliver, in exchange and substitution for and upon cancellation of this
certificate  if  mutilated,  or in lieu of and  in  substitution  for  this
certificate if lost, stolen or destroyed, a new Warrant Certificate of like
tenor and representing an equivalent  right  or  interest,  but  only  upon
receipt  of  evidence  reasonably satisfactory to the Company of such loss,
theft  or  destruction  of  this  Warrant  Certificate  and  indemnity,  if
requested, also reasonably satisfactory to the Company.

SECTION V.  RESERVATION OF SHARES OF WARRANT STOCK.

          There has been  reserved, and the Company shall at all times keep
reserved so long as this Warrant remains outstanding, out of its authorized
Common Stock a number of shares  of  Common Stock sufficient to provide for
the exercise of the rights of purchase  represented  by  this Warrant.  The
transfer agent for the Common Stock and every subsequent transfer agent for
any  shares  of the Company's capital stock issuable upon the  exercise  of
this Warrant will  be  irrevocably  authorized and directed at all times to
reserve such number of authorized shares  as  shall  be  requisite for such
purpose.

SECTION VI.  FRACTIONAL SHARES.

          No  fractional  shares  or  scrip representing fractional  shares
shall be issued upon the exercise of this  Warrant.   With  respect  to any
fraction  of  a  share  called  for  upon the exercise of this Warrant, the
Company shall pay to the Warrantholder  an  amount  in  cash  equal to such
fraction multiplied by the Exercise Price then in effect.

SECTION VII.  ADJUSTMENTS OF EXERCISE PRICE AND NUMBER OF SHARES.

          A.   COMPUTATION   OF   ADJUSTED   EXERCISE  PRICE.   Except   as
hereinafter provided, in case the Company shall  at any time after the date
hereof  (i)  issue  or  sell any shares of Common Stock  (except  in  those
instances referred to in  subsection  F  of  this  Section  VII), including
shares held in the Company's treasury and shares issued upon  the  exercise
of  any option, rights or warrants (with the exception of this Warrant  and
any other  options and warrants outstanding on the date hereof, and without
duplicating  any  adjustments  pursuant  to  clause  (ii) below) and shares
issued upon the direct or indirect conversion or exchange of securities for
shares  of  Common  Stock  (with  the exception of the Company's  Series  A
Cumulative Convertible Preferred Stock  and  Series B Convertible Preferred
Stock (collectively, the "PREFERRED STOCK"), and  without  duplicating  any
adjustments  pursuant  to  clause (ii) below) for a consideration per share
less than the Market Price (as  hereinafter  defined)  on  the  trading day
immediately prior to the date of issuance or sale of such share or  without
consideration,  or  (ii) issue any rights, options or warrants to subscribe
for or purchase or otherwise acquire Common Stock (the "OPTION SECURITIES")
or any evidences of indebtedness,  shares  of  stock  or  other  securities
(other   than   the   Preferred   Stock)  which  are  convertible  into  or
exchangeable,  with or without payment  of  consideration,  for  shares  of
Common Stock (the  "CONVERTIBLE  SECURITIES"),  whether or not the right to
exercise such Option Securities or to convert or  exchange such Convertible
Securities is immediately exercisable or is conditioned upon the passage of
time, the occurrence or non-occurrence of some other  event, or both, for a
consideration  per  share  of Common Stock (calculated in  accordance  with
subsections A(iii) and A(iv)  of  this  Article  VII)  less than the Market
Price on the trading day immediately prior to the date of  issuance of such
Option  Securities  or  Convertible  Securities, then forthwith  upon  such
issuance or sale the Exercise Price shall  (until  another such issuance or
sale)  be  reduced  to  a  price  (calculated  to  the nearest  full  cent)
determined  by  multiplying the Exercise Price immediately  prior  to  such
issuance or sale  by  a fraction, the numerator of which is an amount equal
to the sum of (X) the total  number  of  shares of Common Stock outstanding
immediately prior to such issuance or sale,  multiplied by the Market Price
in  effect  immediately  prior  to  such issuance or  sale,  plus  (Y)  the
aggregate  of the amount of all consideration,  if  any,  received  by  the
Company upon  such  issuance  or  sale, and the denominator of which is the
Market  Price  in  effect  immediately  prior  to  such  issuance  or  sale
multiplied  by the total number  of  shares  of  Common  Stock  outstanding
immediately after  such  issuance  or  sale;  PROVIDED, HOWEVER, that in no
event shall the Exercise Price be adjusted pursuant  to this computation to
an  amount in excess of the Exercise Price in effect immediately  prior  to
such computation, except in the case of a combination of outstanding shares
of Common Stock, as provided by subsection B of this Section VII.

          For the purposes of any computation to be made in accordance with
this subsection A, the following provisions shall be applicable:

               (i)   In  case  of  the issuance or sale of shares of Common
Stock for a consideration part or all of which shall be cash, the amount of
the cash consideration therefor shall  be  deemed  to  be the amount of the
cash received by the Company for such shares (or, if shares  are offered by
the  Company  for  subscription,  the  subscription  price, or, if sold  to
underwriters  or  dealers  the  public  offering  price)  before  deducting
therefrom   any  compensation  paid  or  discount  allowed  in  the   sale,
underwriting  or  purchase  thereof  by  underwriters  or dealers or others
performing  similar  services,  or  any  expenses  incurred  in  connection
therewith.

               (ii)  In case of the issuance or sale (otherwise  than  as a
dividend  or  other  distribution on any stock of the Company) of shares of
Common Stock for a consideration  part  or all of which shall be other than
cash, the amount of the consideration therefor  other  than  cash  shall be
deemed to be the value of such consideration as determined in good faith by
the Board of Directors of the Company.

               (iii)In  case  of  the  issuance  of  Convertible Securities
(other  than  the  Convertible  Securities  described in (iv)  below),  the
aggregate  consideration  received  therefor shall  be  deemed  to  be  the
consideration, if any, received by the  Company  for  the  issuance of such
Convertible Securities, plus the additional minimum consideration,  if any,
to be received by the Company upon the conversion or exchange thereof.

               (iv)   In the case of the issuance of Option Securities, the
aggregate  consideration  received  therefor  shall  be  deemed  to  be the
consideration,  if  any,  received  by the Company for the issuance of such
Option Securities, plus the additional minimum consideration, if any, to be
received by the Company upon the exercise thereof.

               (v)  Shares of Common  Stock  issuable by way of dividend or
other distribution on any stock of the Company shall be deemed to have been
issued immediately after the opening of business  on the date following the
record date for the determination of stockholders entitled  to receive such
dividend  or  other  distribution  and shall be deemed to have been  issued
without consideration.

               (vi)  The reclassification  of  securities  of  the Company,
other  than  shares  of  Common  Stock into securities including shares  of
Common Stock, shall be deemed to involve  the issuance of such shares for a
consideration other than cash immediately prior to the close of business on
the  date  fixed  for  the determination of security  holders  entitled  to
receive such shares, and  the  value of the consideration allocable to such
shares  shall  be  determined  as  provided  in  subsection  (ii)  of  this
subsection A.

               (vii)  The number of  shares of Common Stock at any one time
outstanding shall include the aggregate number of shares issued or issuable
(subject  to  readjustment  upon  the actual  issuance  thereof)  upon  the
exercise of outstanding options, rights,  warrants  and upon the conversion
or exchange of outstanding convertible or exchangeable securities.

               "MARKET PRICE," as of any date, (i) means the average of the
last  reported sale prices for the shares of Common Stock  as  reported  by
National  Association  of  Securities  Dealers Automated Quotation National
Market System ("NASDAQ-NMS") for the five  consecutive  trading days ending
on such date, or (ii) if the NASDAQ-NMS is not the principal trading market
for  the  shares  of  Common  Stock, the average of the last reported  sale
prices on the principal trading market for the Common Stock during the same
period, or (iii) if market value  cannot  be  calculated as of such date on
any  of the foregoing bases, the Market Price shall  be  the  average  fair
market  value  as  reasonably  determined  in  good  faith  by the Board of
Directors of the Company.

          B.   SUBDIVISION AND COMBINATION.  In case the Company  shall  at
any  time  subdivide or combine the outstanding shares of Common Stock, the
Exercise Price  shall forthwith be proportionately decreased in the case of
subdivision or increased in case of combination.

          C.   ADJUSTMENT IN NUMBER OF SHARES.  Upon each adjustment of the
Exercise Price pursuant  to  the provisions of this Section VII, the number
of shares of Warrant Stock issuable upon the exercise of this Warrant shall
be adjusted to the nearest full  share by multiplying a number equal to the
Exercise Price in effect immediately prior to such adjustment by the number
of  shares  of  Warrant  Stock  issuable  upon  exercise  of  this  Warrant
immediately prior to such adjustment  and  dividing the product so obtained
by the adjusted Exercise Price.

          D.   RECLASSIFICATION, CONSOLIDATION,  MERGER,  ETC.   In case of
any  reclassification  or change of the outstanding shares of Common  Stock
(other than a change in  par value to no par value, or from no par value to
par value, or as a result  of a subdivision or combination), or in the case
of any consolidation of the  Company  with,  or merger of the Company into,
another corporation (other than a consolidation  or  merger  in  which  the
Company  is  the  surviving  corporation  and  which does not result in any
reclassification  or  change  of the outstanding shares  of  Common  Stock,
except a change as a result of  a subdivision or combination of such shares
or a change in par value, as aforesaid),  or  in  the  case  of  a  sale or
conveyance  to  another  corporation  of  all  or  substantially all of the
property of the Company, the Warrantholder shall thereafter  have the right
to purchase upon the exercise of this Warrant the kind and number of shares
of   stock   and   other  securities  and  property  receivable  upon  such
reclassification, change,  consolidation,  merger, sale or conveyance as if
the Warrantholder were the owner of the shares  of Warrant Stock underlying
this Warrant immediately prior to any such events  at the Exercise Price in
effect  immediately  prior  to  the record date for such  reclassification,
change, consolidation, merger, sale  or conveyance as if such Warrantholder
had exercised this Warrant.

          E.   SPECIAL ADJUSTMENT.  If  the  purchase price provided for in
any Option Securities, the additional consideration,  if  any, payable upon
the  conversion or exchange of any Convertible Securities or  the  rate  at
which  any  Convertible Securities are convertible into or exchangeable for
Common Stock  shall  change,  or  if  any  Option Securities or Convertible
Securities terminate in whole or in part without being exercised, converted
or exchanged, the Exercise Price in effect at  the time of such event shall
forthwith  be readjusted.  The Exercise Price shall  be  adjusted  to  that
amount which  would  have  been  in  effect  at  such  time had such Option
Securities  or  Convertible Securities outstanding at such  time  initially
been granted, issued  or  sold and the Exercise Price initially adjusted as
provided in subsection A of  this  Article  VII,  except  that  the minimum
amount of additional consideration payable and the total maximum  number of
shares issuable shall be determined after giving effect to such event  (and
any prior event or events).

          F.   NO  ADJUSTMENT  OF  EXERCISE  PRICE  IN  CERTAIN  CASES.  No
adjustment of the Exercise Price shall be made:

               (i)  Upon the issuance or sale of this Warrant or the shares
of  Warrant  Stock  issuable  upon  the  exercise  of  this Warrant, or the
issuance or sale of the Preferred Stock, or upon the issuance  of shares of
Common Stock in connection with the conversion of such Preferred  Stock, or
the  issuance  of  shares  of Common Stock pursuant to Section 2(c) of  the
Registration Rights Agreement  of  even  date  herewith  by  and  among the
Company  and  the Buyer and pursuant to Section 2(b) of the Certificate  of
Designations, Preferences  and  Rights  of  Series  B Convertible Preferred
Stock of the Company;

               (ii)   Upon  the  issuance of options, or  shares  upon  the
exercise  thereof, pursuant to the  Company's  Non-Qualified  Stock  Option
Plan, or any amendment or successor plan thereto;

               (iii)   If  the amount of said adjustment shall be less than
one  cent  ($.01) per share; provided,  however,  that  in  such  case  any
adjustment that  would  otherwise  be  required  then  to  be made shall be
carried  forward  and  shall be made at the time of and together  with  any
adjustment so carried forward, shall amount to at least one cent ($.01) per
Share;

               (iv)  Upon the issuance or sale of shares of Common Stock or
securities which are exercisable or convertible into shares of Common Stock
to employees of the Company  or  its  affiliates,  under  an Employee Stock
Purchase Plan;

               (v)   Upon  the  issuance  of any Option Securities  or  the
issuance of shares of Common Stock upon the  exercise  thereof,  where such
Option  Security  was issued for a consideration price per share of  Common
Stock initially deliverable  upon exercise of such Option Security equal to
or  greater  than the Market Price  in  effect  immediately  prior  to  the
issuance or sale of such Option Security;

               (vi)   Upon the issuance of Convertible Securities where the
conversion price is equal  to  or  greater  than the Market Price in effect
immediately prior to the issuance of such Convertible Securities;

               (vii)Upon  the issuance of Common  Stock  to  non-management
directors of the Company in  an  amount  up  to  Fourteen  Thousand Dollars
($14,000) per such director per year, based upon such method  of  valuation
as may be established from time to time by the Company's Board of Directors
in its reasonable discretion; or

               (viii)Upon  the  issuance  of  an  aggregate  of up to Three
Million  Dollars  ($3,000,000)  of  Common  Stock  or securities which  are
exercisable or convertible into Common Stock at a discount  to  the  Market
Price  as  of the date of such issuance that does not exceed twenty percent
(20%).
