                          (Void after October 1, 2004)


     IGI, Inc., a Delaware  corporation  (the  "Company"),  for value  received,
hereby certifies that Fleet  Bank--N.H.,  a banking and trust company  organized
under the laws of New  Hampshire,  or its  registered  assigns (the  "Registered
Holder"),  is entitled,  subject to the terms set forth below,  to purchase from
the Company, at any time or from time to time on or after September 30, 1999 and
on or  before  October  1, 2004 at not later  than 5:00 p.m.  150,000  shares of
Common Stock, $.01 par value per share (the "Common Stock"),  of the Company, at
a Exercise Price of $2.00 per share unless, by 5:00 p.m., Boston,  Massachusetts
time, on or before September 30, 1999, either (a) all Obligations (as defined in
the Second  Extension  Agreement  dated  March 11, 1999 (the  "Second  Extension
Agreement") by and among the Registered  Holder,  Mellon Bank, N.A., the Company
and  certain of its  subsidiaries)  of the  Borrowers  (as defined in the Second
Extension  Agreement)  to  the  Lenders  (as  defined  in the  Second  Extension
Agreement)  shall  have been paid in full,  in which case this  Warrant  and the
Registered  Holder's rights  hereunder  shall expire,  or (b) the Borrowers have
delivered an acceptable commitment letter,  subject only to documentation and no
further  contingencies of any kind, from a financial  institution  acceptable to
the Lenders,  contemplating a full refinance of the existing  Obligations  which
contemplates  a closing  within thirty (30) days,  in which case this  Warrant's
exercise  start date shall be extended to commence  October 30, 1999;  provided,
however,  if all  Obligations to the Lenders have been paid in full on or before
such  extended  start date,  this  Warrant and the  Registered  Holder's  rights
hereunder  shall expire upon such payment.  The shares issuable upon exercise of
this Warrant,  and the exercise  price per share,  each as adjusted from time to
time pursuant to the provisions of this Warrant,  are hereinafter referred to as
the "Warrant Shares" and the "Exercise Price," respectively.


                                       -1-

Federal agency at the time administering the Securities Act.

     "Registration  Statement"  means  a  registration  statement  filed  by the
Company  with the  Commission  for a public  offering  and sale of Common  Stock
(other  than a  registration  statement  on  Form  S-8 or  Form  S-4,  or  their
successors, or any other form for a similar limited purpose, or any registration
statement  covering  only  securities  proposed  to be  issued in  exchange  for
securities or assets of another corporation).

     "Registrable  Shares"  means  (i) the  Warrant  Shares,  and (ii) any other
shares of Common  Stock  issued in  respect  of such  shares  (because  of stock
splits,  stock  dividends,  reclassifications,   recapitalizations,  or  similar
events);  provided,  however,  that shares of Common Stock which are Registrable
Shares  shall  cease to be  Registrable  Shares (i) upon any sale  pursuant to a
Registration  Statement  or Rule 144 under the  Securities  Act or (ii) upon any
sale in any manner to a person or entity which,  by virtue of Section 13 of this
Warrant, is not entitled to the rights provided by this Warrant.

     "Securities Act" means the Security Act of 1933, as amended, or any similar

     2. Exercise.

     (a) This Warrant may be exercised by the Registered  Holder, in whole or in
part, by  surrendering  this Warrant,  with the purchase form appended hereto as
Exhibit I duly executed by such Registered Holder or by such Registered Holder's
duly authorized  attorney,  at the principal  office of the Company,  or at such
other office or agency as the Company may  designate,  accompanied by payment in
full,  in lawful money of the United  States,  of the Exercise  Price payable in
respect of the number of Warrant Shares issued upon such exercise.

     (b) The Registered  Holder may, at its option,  elect to pay some or all of
the Exercise  Price  payable  upon an exercise of this  Warrant by  cancelling a
portion of this  Warrant  exercisable  for such  number of Warrant  Shares as is
determined  by dividing (i) the total  Exercise  Price payable in respect of the
number of Warrant  Shares being issued upon such  exercise by (ii) the excess of
the Fair  Market  Value per share of Common  Stock as of the  effective  date of
exercise,  as determined pursuant to subsection 2(c) below (the "Exercise Date")
over the Exercise Price per share. If the


                                       -2-



Registered  Holder  wishes to exercise  this Warrant  pursuant to this method of
payment with respect to the maximum number of Warrant Shares  issuable  pursuant
to this method,  then the number of Warrant Shares so issuable shall be equal to
the total number of Warrant  Shares,  minus the product  obtained by multiplying
(x) the total number of Warrant Shares by (y) a fraction, the numerator of which
shall be the Exercise Price per share and the  denominator of which shall be the
Fair Market Value per share of Common Stock as of the  Exercise  Date.  The Fair
Market Value per share of Common Stock shall be determined as follows:

          (i) If the Common Stock is listed on a national  securities  exchange,
     the  Nasdaq  Stock  Market or another  nationally  recognized  exchange  or
     trading  system as of the Exercise Date, the Fair Market Value per share of
     Common  Stock shall be deemed to be the average of the last  reported  sale
     price per share of Common  Stock  thereon for the ten  consecutive  trading
     days ending on the day immediately prior to the Exercise Date.

          (ii) If the  Common  Stock  is not  listed  on a  national  securities
     exchange, the Nasdaq Stock Market or another nationally recognized exchange
     or trading  system as of the Exercise Date, the Fair Market Value per share
     of Common Stock shall be deemed to be the amount most  recently  determined
     in good faith by the Board of Directors to represent  the fair market value
     per share of the Common Stock (including without limitation a determination
     for purposes of granting Common Stock options or issuing Common Stock under
     an  employee  benefit  plan  of the  Company);  and,  upon  request  of the
     Registered  Holder,  the Board of Directors (or a  representative  thereof)
     shall promptly  notify the  Registered  Holder of the Fair Market Value per
     share of  Common  Stock.  Notwithstanding  the  foregoing,  if the Board of
     Directors has not made such a determination  within a forty-five day period
     prior to the  Exercise  Date,  then (A) the Fair Market  Value per share of
     Common Stock shall be the amount next determined in good faith by the Board
     of  Directors  to  represent  the fair market value per share of the Common
     Stock  (including  without  limitation  a  determination  for  purposes  of
     granting  Common  Stock  options or issuing  Common Stock under an employee
     benefit plan of the Company),  (B) the Board of Directors shall make such a
     determination  within 15 days of a request by the Registered Holder that it
     do so, and (C) the  exercise of this  Warrant  pursuant to this  subsection
     2(b) shall be delayed until such determination is made.

     (c) Each  exercise of this  Warrant  shall be deemed to have been  effected
immediately  prior to the close of  business  on the day on which  this  Warrant
shall have been surrendered to the Company as provided in subsection 2(a) above.
At such time, the person or persons in whose name or names any  certificates for
Warrant  Shares shall be issuable  upon such  exercise as provided in subsection
2(d) below shall be deemed to have become the holder or holders of record of the
Warrant Shares represented by such certificates.


                                      -3-



     (d) As soon as practicable after the exercise of this Warrant in full or in
part, and in any event within 10 days thereafter,  the Company,  at its expense,
will cause to be issued in the name of, and delivered to, the Registered Holder,
or as such  Registered  Holder  (upon  payment by such Holder of any  applicable
transfer taxes) may direct:

          (i) a  certificate  or  certificates  for the  number of full  Warrant
     Shares to which such Registered Holder shall be entitled upon such exercise
     plus, in lieu of any fractional share to which such Registered Holder would
     otherwise be entitled,  cash in an amount determined  pursuant to Section 4
     hereof; and

          (ii) in case such  exercise is in part only, a new warrant or warrants
     (dated the date hereof) of like tenor, calling in the aggregate on the face
     or faces  thereof for the number of Warrant  Shares equal  (without  giving
     effect to any  adjustment  therein) to the number of such shares called for
     on the face of this Warrant  minus the sum of (a) the number of such shares
     purchased by the  Registered  Holder upon such exercise plus (b) the number
     of Warrant Shares (if any) covered by the portion of this Warrant cancelled
     in payment of the Exercise  Price  payable upon such  exercise  pursuant to
     subsection 2(b) above.

     (e)  Notwithstanding  the foregoing,  this Warrant shall become immediately
exercisable  by the  Registered  Holder upon (i) the  occurrence  of an Event of
Default (as defined in the Second Extension  Agreement) or (ii) the mailing date
of written  notice by the Company of its  intention  to exercise its right under
Section 8 to redeem Available Warrant Shares (as defined under subsection 8(a)).

     3. Adjustments.

     (a) General. The Exercise Price shall be subject to adjustment from time to
time pursuant to the terms of this Section 3.

     (b) Diluting Issuances.

          (i) Special  Definitions.  For purposes of this  subsection  3(b), the
     following definitions shall apply:

               (A) "Option" shall mean rights,  options or warrants to subscribe
          for,  purchase  or  otherwise  acquire  Common  Stock  or  Convertible
          Securities,  excluding  options described in clause (II) of subsection
          3(b)(i)(D) below.

               (B)  "Original  Issue  Date"  shall  mean the date on which  this
          Warrant was first issued.


                                       -4-



               (C)  "Convertible   Securities"   shall  mean  any  evidences  of
          indebtedness,  shares  or  other  securities  directly  or  indirectly
          convertible into or exchangeable for Common Stock.

               (D) "Additional  Shares of Common Stock" shall mean all shares of
          Common  Stock  issued (or,  pursuant to  subsection  3(b)(iii)  below,
          deemed to be issued) by the  Company  after the  Original  Issue Date,
          other than shares of Common Stock issued or issuable:

               (I)  by reason of a  dividend,  stock  split,  split-up  or other
                    distribution  on shares of Common  Stock  that are  excluded
                    from the definition of Additional  Shares of Common Stock by
                    this clause (I); or

              (II)  to employees or directors of, or consultants to, the Company
                    pursuant to a plan  adopted by the Board of Directors of the
                    Company.

          (ii) No Adjustment of Exercise  Price.  No adjustments to the Exercise
     Price shall be made unless the consideration per share (determined pursuant
     to subsection  3(b)(v)) for an  Additional  Share of Common Stock issued or
     deemed to be  issued by the  Company  is less  than the  Exercise  Price in
     effect  on the  date  of,  and  immediately  prior  to,  the  issue of such
     Additional Shares.

          (iii) Issue of Securities  Deemed Issue of Additional Shares of Common
     Stock.  If the Company at any time or from time to time after the  Original
     Issue Date shall issue any Options or Convertible Securities or shall fix a
     record  date for the  determination  of holders of any class of  securities
     entitled to receive any such Options or  Convertible  Securities,  then the
     maximum  number of shares of Common  Stock (as set forth in the  instrument
     relating  thereto without regard to any provision  contained  therein for a
     subsequent  adjustment  of such number)  issuable upon the exercise of such
     Options or, in the case of Convertible Securities and Options therefor, the
     conversion or exchange of such Convertible  Securities,  shall be deemed to
     be  Additional  Shares of Common  Stock issued as of the time of such issue
     or, in case such a record  date shall have been  fixed,  as of the close of
     business on such record date,  provided  that  Additional  Shares of Common
     Stock shall not be deemed to have been issued unless the  consideration per
     share (determined pursuant to subsection 3(b)(v) hereof) of such Additional
     Shares of Common Stock would be less than the  Exercise  Price in effect on
     the date of and  immediately  prior to such issue,  or such record date, as
     the case  may be,  and  provided  further  that in any  such  case in which
     Additional Shares of Common Stock are deemed to be issued:

               (A) No further  adjustment  in the  Exercise  Price shall be made
          upon the  subsequent  issue of  Convertible  Securities  or  shares of
          Common Stock


                                       -5-



upon the exercise of such Options or conversion or exchange of such  Convertible
Securities;

               (B) If such  Options or  Convertible  Securities  by their  terms
          provide,  with the passage of time or  otherwise,  for any increase in
          the  consideration   payable  to  the  Company,   upon  the  exercise,
          conversion or exchange  thereof,  the Exercise Price computed upon the
          original  issue thereof (or upon the  occurrence of a record date with
          respect thereto), and any subsequent adjustments based thereon, shall,
          upon any such increase  becoming  effective,  be recomputed to reflect
          such  increase  insofar  as it affects  such  Options or the rights of
          conversion or exchange under such Convertible Securities;

               (C) Upon the expiration or termination of any unexercised Option,
          the Exercise Price shall not be readjusted,  but the Additional Shares
          of Common Stock deemed  issued as the result of the original  issue of
          such  Option  shall  not be  deemed  issued  for the  purposes  of any
          subsequent adjustment of the Exercise Price;

               (D) In the event of any  change in the number of shares of Common
          Stock issuable upon the exercise, conversion or exchange of any Option
          or  Convertible  Security,  including,  but not  limited  to, a change
          resulting  from the  anti-dilution  provisions  thereof,  the Exercise
          Price then in effect shall  forthwith be  readjusted  to such Exercise
          Price as would have  obtained had the  adjustment  which was made upon
          the issuance of such Option or  Convertible  Security not exercised or
          converted  prior to such  change  been  made  upon  the  basis of such
          change; and

               (E) No  readjustment  pursuant  to Clause (B) or (D) above  shall
          have the effect of  increasing  the Exercise  Price to an amount which
          exceeds the lower of (i) the Exercise Price on the original adjustment
          date,  or (ii) the Exercise  Price that would have  resulted  from any
          issuances of  Additional  Shares of Common Stock  between the original
          adjustment date and such readjustment date.

          (iv)  Adjustment of Exercise Price Upon Issuance of Additional  Shares
     of  Common  Stock.  In the event the  Company  shall at any time  after the
     Original  Issue Date issue  Additional  Shares of Common  Stock  (including
     Additional  Shares  of  Common  Stock  deemed  to  be  issued  pursuant  to
     subsection  3(b)(iii),  but  excluding  shares  issued  as  a  dividend  or
     distribution or upon a stock split or combination as provided in subsection
     3(c)), without consideration or for a consideration per share less than the
     Exercise  Price  in  effect  on the date of and  immediately  prior to such
     issue,  then and in such  event,  such  Exercise  Price  shall be  reduced,
     concurrently  with such issue, to a price  (calculated to the nearest cent)
     determined  by  multiplying  such  Exercise  Price by a  fraction,  (A) the
     numerator  of which  shall be (1) the  number of  shares  of  Common  Stock
     outstanding  immediately  prior to such issue plus (2) the number of shares
     of Common Stock which the


                                       -6-



     aggregate  consideration  received or to be received by the Company for the
     total number of Additional  Shares of Common Stock so issued would purchase
     at such  Exercise  Price;  and (B) the  denominator  of which  shall be the
     number  of shares of Common  Stock  outstanding  immediately  prior to such
     issue plus the number of such Additional  Shares of Common Stock so issued;
     provided that, (i) for the purpose of this subsection 3(b)(iv),  all shares
     of Common  Stock  issuable  upon  exercise  or  conversion  of  Options  or
     Convertible Securities outstanding immediately prior to such issue shall be
     deemed to be outstanding (other than shares excluded from the definition of
     "Additional  Shares of Common Stock" by virtue of clause (II) of subsection
     3(b)(i)(D)),  and (ii) the number of shares of Common Stock deemed issuable
     upon  conversion of such  outstanding  Options and  Convertible  Securities
     shall  not  give  effect  to any  adjustments  to the  conversion  price or
     conversion  rate of such Options or Convertible  Securities  resulting from
     the  issuance of  Additional  Shares of Common Stock that is the subject of
     this calculation.

     Notwithstanding  the foregoing,  the applicable Exercise Price shall not be
so reduced at such time if the amount of such reduction  would be an amount less
than $.05,  but any such  amount  shall be carried  forward and  reduction  with
respect  thereto made at the time of and together with any subsequent  reduction
which,  together  with such  amount  and any other  amount or amounts so carried
forward, shall aggregate $.05 or more.

          (v)  Determination of  Consideration.  For purposes of this subsection
     3(b),  the  consideration  received  by the  Company  for the  issue of any
     Additional Shares of Common Stock shall be computed as follows:

               (A) Cash and Property: Such consideration shall:

                    (I)  insofar as it  consists  of cash,  be  computed  at the
               aggregate of cash received by the Company, excluding amounts paid
               or payable for accrued interest or accrued dividends;

                    (II) insofar as it consists of property  other than cash, be
               computed  at the fair  market  value  thereof at the time of such
               issue, as determined in good faith by the Board of Directors; and

                    (III) in the event  Additional  Shares  of Common  Stock are
               issued  together  with other shares or securities or other assets
               of the  Company  for  consideration  which  covers  both,  be the
               proportion  of  such  consideration  so  received,   computed  as
               provided  in clauses (I) and (II) above,  as  determined  in good
               faith by the Board of Directors.

               (B) Options and Convertible  Securities.  The  consideration  per
          share received by the Company for Additional Shares of Common


                                       -7-




          Stock  deemed to have been issued  pursuant to  subsection  3(b)(iii),
          relating to Options and Convertible Securities, shall be determined by
          dividing

                    (x) the total amount,  if any, received or receivable by the
               Company  as  consideration  for  the  issue  of such  Options  or
               Convertible  Securities,  plus the  minimum  aggregate  amount of
               additional   consideration  (as  set  forth  in  the  instruments
               relating  thereto,  without  regard  to any  provision  contained
               therein  for  a  subsequent  adjustment  of  such  consideration)
               payable to the Company  upon the  exercise of such Options or the
               conversion or exchange of such Convertible Securities,  or in the
               case of Options for Convertible Securities,  the exercise of such
               Options for Convertible Securities and the conversion or exchange
               of such Convertible Securities, by

                    (y) the  maximum  number of  shares of Common  Stock (as set
               forth in the instruments relating thereto,  without regard to any
               provision  contained therein for a subsequent  adjustment of such
               number)  issuable  upon  the  exercise  of  such  Options  or the
               conversion or exchange of such Convertible Securities.

     (c)  Recapitalizations.  If  outstanding  shares of Common  Stock  shall be
subdivided  into a greater  number of shares or a dividend in Common Stock shall
be paid in respect of Common  Stock,  the Exercise  Price in effect  immediately
prior  to  such  subdivision  or at the  record  date  of  such  dividend  shall
simultaneously  with the  effectiveness of such subdivision or immediately after
the record date of such  dividend be  proportionately  reduced.  If  outstanding
shares of Common Stock shall be combined  into a smaller  number of shares,  the
Exercise  Price  in  effect   immediately  prior  to  such  combination   shall,
simultaneously  with the effectiveness of such combination,  be  proportionately
increased.

     (d)  Mergers,  etc.  If there shall  occur any  capital  reorganization  or
reclassification  of the  Common  Stock  (other  than a change in par value or a
subdivision  or combination  as provided for in subsection  3(c) above),  or any
consolidation  or merger of the Company with or into another  corporation,  or a
transfer of all or substantially all of the assets of the Company, then, as part
of any such reorganization, reclassification,  consolidation, merger or sale, as
the case may be, lawful provision shall be made so that the Registered Holder of
this Warrant shall have the right thereafter to receive upon the exercise hereof
the kind and amount of shares of stock or other  securities  or  property  which
such Registered Holder would have been entitled to receive if, immediately prior
to any such reorganization, reclassification,  consolidation, merger or sale, as
the case may be, such Registered  Holder had held the number of shares of Common
Stock which were then issuable  upon the exercise of this  Warrant.  In any such
case,  appropriate  adjustment  (as  reasonably  determined in good faith by the
Board of  Directors  of the  Company)  shall be made in the  application  of the
provisions set forth herein with respect to the rights and interests  thereafter
of the Registered Holder of this Warrant, such that the


                                       -8-



provisions  set forth in this  Section 3 (including  provisions  with respect to
adjustment of the Exercise Price) shall  thereafter be applicable,  as nearly as
is  reasonably  practicable,  in  relation  to any  shares  of  stock  or  other
securities or property thereafter deliverable upon the exercise of this Warrant.

     (e) Adjustment in Number of Warrant Shares. When any adjustment is required
to be made in the Exercise Price, the number of Warrant Shares issuable upon the
exercise of this Warrant  shall be changed to the number  determined by dividing
(i) an amount equal to the number of shares  issuable  upon the exercise of this
Warrant  immediately prior to such adjustment,  multiplied by the Exercise Price
in effect  immediately  prior to such adjustment,  by (ii) the Exercise Price in
effect immediately after such adjustment.

     (f)  Certificate of Adjustment.  When any adjustment is required to be made
pursuant to this Section 3, the Company shall  promptly  mail to the  Registered
Holder a certificate  setting forth the Exercise Price after such adjustment and
setting forth a brief  statement of the facts  requiring such  adjustment.  Such
certificate  shall  also  set  forth  the  kind  and  amount  of  stock or other
securities or property into which this Warrant  shall be  exercisable  following
such adjustment.

     4. Fractional  Shares.  The Company shall not be required upon the exercise
of this Warrant to issue any  fractional  shares,  but shall make an  adjustment
therefor  in cash on the  basis of the Fair  Market  Value  per  share of Common
Stock, as determined pursuant to subsection 2(b) above.

     5. Requirements for Transfer.

     (a) This Warrant and the Warrant  Shares  shall not be sold or  transferred
unless either (i) they first shall have been registered under the Securities Act
of 1933, as amended (the "Securities Act"), or (ii) the Company first shall have
been furnished with an opinion of legal counsel,  reasonably satisfactory to the
Company,  to  the  effect  that  such  sale  or  transfer  is  exempt  from  the
registration requirements of the Act.

     (b)  Notwithstanding  the foregoing,  no registration or opinion of counsel
shall  be  required  for  (i) a  transfer  by a  Registered  Holder  which  is a
partnership  to a  partner  of such  partnership  or a retired  partner  of such
partnership  who  retires  after the date  hereof,  or to the estate of any such
partner or retired partner, if the transferee agrees in writing to be subject to
the terms of this Section 5, (ii) a transfer  made in  accordance  with Rule 144
under the Act, or (iii) a transfer by a Registered Holder which is a corporation
to an  affiliate,  as  defined  under  Rule 144 of the  Securities  Act,  if the
transferee agrees in writing to be subject to the terms of this Section.


                                       -9-



     (c)  Each  certificate  representing  Warrant  Shares  shall  bear a legend
substantially in the following form:

          "The  securities   represented  by  this  certificate  have  not  been
          registered  under the Securities Act of 1933, as amended,  and may not
          be offered,  sold or otherwise  transferred,  pledged or  hypothecated
          unless and until such  securities are registered  under such Act or an
          opinion of counsel  satisfactory  to the  Company is  obtained  to the
          effect that such registration is not required."


The foregoing  legend shall be removed from the  certificates  representing  any
Warrant  Shares,  at the  request  of the holder  thereof,  at such time as they
become eligible for resale pursuant to Rule 144(k) under the Act.

     6. No  Impairment.  The Company  will not, by  amendment  of its charter or
through reorganization,  consolidation,  merger, dissolution,  sale of assets or
any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms of this Warrant,  but will at all times in good faith assist
in the  carrying  out of all such terms and in the taking of all such  action as
may be necessary or  appropriate in order to protect the rights of the holder of
this Warrant against impairment.

     7.  Liquidating  Dividends.  If the  Company  pays a  dividend  or  makes a
distribution on the Common Stock payable  otherwise than in cash out of earnings
or earned surplus  (determined in accordance with generally accepted  accounting
principles)  except for a stock  dividend  payable in shares of Common  Stock (a
"Liquidating  Dividend"),  then  the  Company  will  pay  or  distribute  to the
Registered Holder of this Warrant,  upon the exercise hereof, in addition to the
Warrant Shares issued upon such exercise,  the Liquidating  Dividend which would
have been paid to such  Registered  Holder if he had been the owner of record of
such Warrant Shares immediately prior to the date on which a record is taken for
such  Liquidating  Dividend or, if no record is taken,  the date as of which the
record holders of Common Stock entitled to such dividends or distribution are to
be determined.

     8. Optional Redemption.

     (a) At any time,  the Company may, at its option,  redeem all, but not less
than  all,  of the  Warrant  Shares  for  which the  Registered  Holder  has not
exercised its right to be issued (the  "Available  Warrant  Shares"),  by paying
$3.33 per Available  Warrant Share (subject to appropriate  adjustment for stock
splits,  stock  dividends,   combinations  or  other  similar  recapitalizations
affecting such shares) in cash for each


                                      -10-



Available  Warrant  Share  then  redeemed   (hereinafter   referred  to  as  the
"Redemption  Price");   provided,   however,  that  the  Registered  Holder  may
immediately exercise its Warrant or Warrants until such time on or 15 days prior
to the Redemption Date (as defined below).

     (b) At  least  15 days  prior  to the  date  fixed  for any  redemption  of
Available  Warrant Shares  (hereinafter  referred to as the "Redemption  Date"),
written  notice  shall be mailed,  by first class or  registered  mail,  postage
prepaid, to the Registered Holder,  notifying such holder of the election of the
Company to redeem such Available Warrant Shares,  specifying the Redemption Date
and calling upon the  Registered  Holder to  surrender  to the  Company,  in the
manner and at the place  designated,  its Warrant or Warrants,  representing the
Available Warrant Shares to be redeemed (such notice is hereinafter  referred to
as the "Redemption  Notice"). On or prior to the Redemption Date (subject to the
Registered  Holder's  right to exercise  such Warrants  prior to the  Redemption
Date),   the  Registered   Holder  shall   surrender  its  Warrant  or  Warrants
representing  Available Warrant Shares to the Company,  in the manner and at the
place designated in the Redemption Notice, and thereupon the Redemption Price of
such  shares  shall be  payable to the order of the  Registered  Holder and each
surrendered  Warrant shall be  cancelled.  From and after the  Redemption  Date,
unless  there shall have been a default in payment of the  Redemption  Price (or
the Registered Holder has exercised the Warrants prior to such Redemption Date),
all rights of the Registered  Holder designated for redemption in the Redemption
Notice as the  Registered  Holder  (except the right to receive  the  Redemption
Price without  interest upon  surrender of the Warrant) shall cease with respect
to the Warrant or Warrants  representing the Available Warrant Shares,  and such
Warrant or Warrants  shall not  thereafter  be  transferred  on the books of the
Company or be deemed to be outstanding for any purpose whatsoever.

     9. Notices of Record Date, etc. In case:

     (a) the Company  shall take a record of the holders of its Common Stock (or
other stock or  securities  at the time  deliverable  upon the  exercise of this
Warrant) for the purpose of  entitling or enabling  them to receive any dividend
or other distribution,  or to receive any right to subscribe for or purchase any
shares of stock of any class or any other  securities,  or to receive  any other
right; or

     (b) of any capital  reorganization of the Company,  any reclassification of
the capital  stock of the Company,  any  consolidation  or merger of the Company
with or into another  corporation (other than a consolidation or merger in which
the Company is the surviving  entity),  or any transfer of all or  substantially
all of the assets of the Company; or

     (c) of the voluntary or involuntary dissolution,  liquidation or winding-up
of the Company, then, and in each such case, the Company will mail or


                                      -11-



cause to be mailed to the Registered Holder of this Warrant a notice specifying,
as the case  may be,  (i) the  date on  which a  record  is to be taken  for the
purpose of such  dividend,  distribution  or right,  and  stating the amount and
character of such dividend, distribution or right, or (ii) the effective date on
which such reorganization,  reclassification,  consolidation,  merger, transfer,
dissolution, liquidation or winding-up is to take place, and the time, if any is
to be fixed,  as of which the  holders of record of Common  Stock (or such other
stock or securities at the time  deliverable  upon the exercise of this Warrant)
shall be entitled to exchange  their shares of Common Stock (or such other stock
or  securities)  for  securities  or  other  property   deliverable   upon  such
reorganization, reclassification,  consolidation, merger, transfer, dissolution,
liquidation  or  winding-up.  Such notice shall be mailed at least ten (10) days
prior to the  record  date or  effective  date for the event  specified  in such
notice.

     10.  Reservation  of Stock.  The Company will at all times reserve and keep
available,  solely for issuance and delivery  upon the exercise of this Warrant,
such number of Warrant Shares and other stock,  securities and property, as from
time to time shall be issuable upon the exercise of this Warrant.

     11.  Exchange of Warrants.  Upon the surrender by the Registered  Holder of
any Warrant or  Warrants,  properly  endorsed,  to the Company at the  principal
office of the Company,  the Company will, subject to the provisions of Section 5
hereof, issue and deliver to or upon the order of such Registered Holder, at the
Company's  expense, a new Warrant or Warrants of like tenor, in the name of such
Registered  Holder or as such Registered Holder (upon payment by such Registered
Holder of any applicable transfer taxes) may direct, calling in the aggregate on
the face or faces thereof for the number of shares of Common Stock called for on
the face or faces of the Warrant or Warrants so surrendered.

     12.   Replacement  of  Warrants.   Upon  receipt  of  evidence   reasonably
satisfactory  to the Company of the loss,  theft,  destruction  or mutilation of
this Warrant and (in the case of loss, theft or destruction) upon delivery of an
indemnity agreement (with surety if reasonably required) in an amount reasonably
satisfactory to the Company,  or (in the case of mutilation)  upon surrender and
cancellation  of this Warrant,  the Company will issue,  in lieu thereof,  a new
Warrant of like tenor.

     13. Transfers, etc.

     (a) The Company will maintain a register containing the name and address of
the Registered  Holder of this Warrant.  Any Registered Holder may change its or
his  address as shown on the warrant  register by written  notice to the Company
requesting such change.


                                      -12-



     (b) Subject to the  provisions  of Section 5 hereof,  this  Warrant and all
rights hereunder are  transferable,  in whole or in part, upon surrender of this
Warrant with a properly  executed  assignment (in the form of Exhibit II hereto)
at the principal office of the Company.

     (c) Until any transfer of this Warrant is made in the warrant register, the
Company may treat the  Registered  Holder of this Warrant as the absolute  owner
hereof for all  purposes;  provided,  however,  that if and when this Warrant is
properly  assigned in blank,  the Company  may (but shall not be  obligated  to)
treat  the  bearer  hereof  as the  absolute  owner  hereof  for  all  purposes,
notwithstanding any notice to the contrary.

     14. Mailing of Notices,  etc. All notices and other communications from the
Company to the Registered  Holder of this Warrant shall be mailed by first-class
certified or registered mail,  postage prepaid,  to the address furnished to the
Company in writing by the last Registered  Holder of this Warrant who shall have
furnished  an  address  to  the  Company  in  writing.  All  notices  and  other
communications  from the  Registered  Holder of this  Warrant  or in  connection
herewith to the Company shall be mailed by  first-class  certified or registered
mail,  postage prepaid,  to the Company at its principal office set forth below.
If the Company should at any time change the location of its principal office to
a place other than as set forth below,  it shall give prompt  written  notice to
the  Registered  Holder of this Warrant and  thereafter  all  references in this
Warrant to the location of its principal  office at the particular time shall be
as so specified in such notice.

     15. No Rights as  Stockholder.  Until the  exercise  of this  Warrant,  the
Registered  Holder of this  Warrant  shall not have or  exercise  any  rights by
virtue hereof as a stockholder of the Company.

     16.  Change or Waiver.  Any term of this  Warrant  may be changed or waived
only by an instrument in writing  signed by the party against which  enforcement
of the change or waiver is sought.

     17.  Headings.  The  headings in this Warrant are for purposes of reference
only and shall not limit or  otherwise  affect the meaning of any  provision  of
this Warrant.

     18.  Governing  Law.  This  Warrant  will be governed by and  construed  in
accordance with the laws of Delaware.

     19. Registration Rights.


                                      -13-



     (a) The Registered  Holder shall have the registration  rights with respect
to the  Warrant  Shares  as  specified  in  Section  9 of the  Second  Extension
Agreement.

     (b)  Furthermore,  the  Registered  Holder shall be entitled to "piggyback"
registration  rights  for so long as the  Registered  Holder  shall own  Warrant
Shares.  Whenever the Company  proposes to file a Registration  Statement (other
than  pursuant to  subsection  19(a) at any time and from time to time, it will,
prior to such  filing,  give  written  notice  to the  Registered  Holder of its
intention to do so and, upon the written request of the Registered  Holder given
within 20 days after the Company provides such notice (which request shall state
the intended  method of disposition  of such  Registrable  Shares),  the Company
shall use its best efforts to cause all Registrable Shares which the Company has
been requested by such Registered  Holder to register to be registered under the
Securities Act to the extent necessary to permit their sale or other disposition
in accordance with the intended methods of distribution specified in the request
of the  Registered  Holder;  provided  that the Company  shall have the right to
postpone or withdraw any  registration  effected  pursuant to  subsection  19(b)
without  obligation to the Registered  Holder or any persons or entities to whom
the rights under this Warrant are  transferred  by the  Registered  Holder,  its
successors or assigns pursuant to Section 13 hereof.

     (c) In connection with any registration under subsection 19(b) involving an
underwriting,  the Company  shall not be  required  to include  any  Registrable
Shares in such  registration  unless the holders thereof accept the terms of the
underwriting as agreed upon between the Company and the underwriters selected by
it (provided that such terms must be consistent  with this  Warrant).  If in the
opinion of the  managing  underwriter  it is  appropriate  because of  marketing
factors  to limit  the  number  of  Registrable  Shares  to be  included  in the
offering, then the Company shall be required to include in the registration only
that  number of  Registrable  Shares,  if any,  which the  managing  underwriter
believes should be included therein.  If the number of Registrable  Shares to be
included in the offering in accordance with the foregoing is less than the total
number of shares which the holders of  Registrable  Shares have  requested to be
included, then the holders of Registrable Shares who have requested registration
and other  holders of securities  entitled to include them in such  registration
shall  participate in the registration pro rata based upon their total ownership
of shares of Common Stock (giving effect to the conversion  into Common Stock of
all securities convertible  thereinto).  If any holder would thus be entitled to
include more securities than such holder requested to be registered,  the excess
shall be  allocated  among  other  requesting  holders  pro  rata in the  manner
described in the preceding sentence.

     20. Registration Procedures. If and whenever the Company is required by the
provisions of this Warrant to use its best efforts to effect the registration of
any of the Registrable Shares under the Securities Act, the Company shall:


                                      -14-



          (a)  furnish to the  Registered  Holder  such  number of copies as the
     Registered Holder shall reasonably  request of the prospectus,  including a
     preliminary  prospectus  and any  amendments  or  supplements  thereto,  in
     conformity with the requirements of the Securities Act;

          (b) use its best efforts to register or qualify the Registrable Shares
     covered by the  Registration  Statement  under the securities  laws of such
     states  as  the  Registered  Holder  shall  reasonably  request;  provided,
     however,  that the Company  shall not be required in  connection  with this
     subsection  20(b) to qualify as a foreign  corporation or execute a general
     consent to service of process in any jurisdiction;

          (c)  promptly  notify  the  Registered  Holder,  if  the  Company  has
     delivered  preliminary or final  prospectuses to the Registered  Holder and
     after  having  done so,  the  prospectus  is  amended  to  comply  with the
     requirements  of the Securities  Act and, if requested by the Company,  the
     Registered  Holder  shall  immediately  cease  making  offers  or  sales of
     Registrable  Shares  under  the  Registration   Statement  and  return  all
     prospectuses  to the  Company.  The  Company  shall  promptly  provide  the
     Registered Holder with revised  prospectuses and,  following receipt of the
     revised prospectuses,  the Registered Holder shall be free to resume making
     offers and sales of the Registrable Shares; and

          (d) pay the expenses  incurred by it in complying with its obligations
     under this Warrant in connection with  registration  rights,  including all
     registration  and filing  fees,  exchange  listing  fees,  expenses for the
     preparation of the  Registration  Statement,  prospectus and any amendments
     and supplements thereto, printing and photocopy expenses, fees and expenses
     of counsel for the Company,  and fees and expenses of  accountants  for the
     Company, but excluding:  (i) selling commissions or underwriting  discounts
     incurred by the Registered  Holder in connection  with sales of Registrable
     Shares under the  Registration  Statement and (ii) the fees and expenses of
     any counsel retained by the Registered Holder.

     21. Requirements of Registered Holder. The Company shall not be required to
effect the  registration of any of the  Registrable  Shares under the Securities
Act pursuant to this Warrant unless:

          (a) the Registered  Holder owning such shares furnishes to the Company
     in  writing  such  information  regarding  such  Registered  Holder and the
     proposed  sale of  Registrable  Shares  by such  Registered  Holder  as the
     Company may reasonably  request in writing in connection with the filing of
     a Registration Statement or as shall be required in connection therewith by
     the Commission or any state securities law authorities; and

          (b) Such  Registered  Holder  shall have  provided  to the Company its
     written  agreement  that in the  event  of any  registration  of any of the
     Registrable


                                      -15-



     Shares under the Securities Act pursuant to this Warrant,  each  Registered
     Holder will  indemnify  the Company and its officers and directors and each
     person,  if any,  who  controls  any  thereof  (within  the  meaning of the
     Securities Act) against any and all claims, losses, damages and liabilities
     (or  actions  in  respect  thereof)  arising  out of or based on any untrue
     statement (or alleged  untrue  statement) of any material fact contained in
     any   prospectus   or  other   document   incident  to  any   registration,
     qualification  or  compliance  (or in any related  Registration  Statement,
     notification  or the like) or any omission  (or alleged  omission) to state
     therein any  material  fact  required to be stated  therein or necessary to
     make the statement therein not misleading,  and such Registered Holder will
     reimburse  the Company and each other person  indemnified  pursuant to this
     Section  21 for any legal and any other  expenses  reasonably  incurred  in
     connection with  investigating or defending any such claim,  loss,  damage,
     liability or action;  provided,  however,  that this Section 21 shall apply
     only if (and only to the extent  that) such  statement or omission was made
     in  reliance  upon  written  information  furnished  to the  Company  in an
     instrument  duly  executed  by such  Registered  Holder  and  stated  to be
     specifically  for use in such  prospectus  or other  document  (or  related
     Registration  Statement,  notification  or the  like) or any  amendment  or
     supplement  thereto;  and,  provided further that each Registered  Holder's
     liability  hereunder with respect to any particular  registration  shall be
     limited to an amount equal to the net proceeds  received by such Registered
     Holder from the Registrable  Securities  sold by such Registered  Holder in
     such registration.

     22.  Indemnification by Company. In the event of any registration of any of
the  Registrable  Shares under the Securities Act pursuant to this Warrant,  the
Company will indemnify each  Registered  Holder and each person who controls the
Registered Holder (within the meaning of the Securities Act) against any and all
claims,  losses, damages and liabilities (or actions in respect thereof) arising
out of or based on any untrue  statement  (or alleged  untrue  statement) of any
material  fact  contained in any  prospectus or other  document  incident to any
registration,  qualification  or  compliance  (or  in any  related  Registration
Statement,  notification  or the like) or any omission (or alleged  omission) to
state therein any material  fact  required to be stated  therein or necessary to
make the statements  therein not misleading,  or any violation by the Company of
any rule or regulation  promulgated  under the  Securities Act applicable to the
Company  and  relating  to any action or  inaction  required  of the  Company in
connection with any such registration,


                                      -16-



qualification or compliance, and the Company will reimburse each such Registered
Holder and  controlling  person for any legal and any other expenses  reasonably
incurred in connection  with  investigating  or defending any such claim,  loss,
damage,  liability or action;  provided,  however,  that the Company will not be
liable in any such  case to the  extent  that any such  claim,  loss,  damage or
liability  arises out of or is based on any untrue  statement or omission  based
upon written information furnished to the Company in an instrument duly executed
by such Registered Holder or controlling person and specifically for use in such
prospectus or other document.
