admitted to trading on any such exchange, the representative closing sale price
of the Common Stock as reported by the National Association of Securities

              This Warrant, together with warrants of like tenor, constituting
in the aggregate Warrants to purchase 2,912,612 Warrant Shares, was originally
issued pursuant to a Preferred Stock and Warrant Purchase Agreement (the
"Purchase Agreement") between the Company and the Holder in connection with the
Holder's  purchase of units in a private placement (THE "OFFERING") of an
aggregate of thirty (30) units (THE "OFFERING UNITS"), each Offering Unit
consisting of (a) 1,000 shares of 5% Series B Preferred Stock (the "PREFERRED
STOCK"), $100.00 stated value, and (b) 97,087 Class L Warrants to purchase
97,087 shares of Common Stock.

1.     EXERCISE OF WARRANT.

              (a)    This Warrant may be exercised in whole at any time, or in
part from time to time, commencing on February 16, 1999 and prior to 5:00 P.M.,
Eastern Standard Time, on February 16, 2009 by the Holder:

                     (i)    by the surrender of this Warrant (with the
              subscription form at the end hereof duly executed) at the address
              set forth in Section 12(a) hereof, together with proper payment of
              the Aggregate Warrant Price, or the proportionate part thereof if
              this Warrant is exercised in part, with payment for the Warrant
              Shares made by certified or official bank check payable to the
              order of the Company; or

                     (ii)   by the surrender of this Warrant (with the cashless
              exercise form at the end hereof duly executed) (a "CASHLESS
              EXERCISE") and payment of $.001 per Warrant Share at the address
              set forth in Section 12(a) hereof.  Such presentation and
              surrender shall be deemed a waiver of the Holder's obligation to
              pay the Aggregate Warrant Price, or the proportionate part thereof
              if this Warrant is exercised in part.  In the event of a Cashless
              Exercise, the Holder shall exchange its Warrant for that number of
              Warrant Shares subject to such Cashless Exercise multiplied by a
              fraction, the numerator of which shall be the difference between
              the then Current Market Price and the Per Share Warrant Price, and
              the denominator of which shall be the then Current Market Price.
              For purposes of any computation under this Section 1(a), the then
              Current Market Price shall be based on the trading day prior to
              the Cashless Exercise.

              (b)    If this Warrant is exercised in part, this Warrant must be
exercised for a number of whole shares of the Common Stock and the Holder is
entitled to receive a new Warrant covering the Warrant Shares that have not
been exercised and setting forth the proportionate part of the Aggregate
Warrant Price applicable to such Warrant Shares.  Upon surrender of this
Warrant, the Company will (i) issue a certificate or certificates in the name
of the Holder for the largest number of whole shares of the Common Stock to
which the Holder shall be entitled and, if this Warrant is exercised in whole,
in lieu of any fractional share of the Common Stock to which the Holder shall
be entitled, pay to the Holder cash in an amount equal to the fair value of
such fractional share (determined in such reasonable manner as the board of
directors of the Company shall determine), and (ii) deliver the other
securities and properties receivable upon the exercise of this Warrant, or the
proportionate part thereof if this Warrant is exercised in part, pursuant to
the provisions of this Warrant.

2.     RESERVATION OF WARRANT SHARES; LISTING.  The Company agrees that, prior
to the expiration of this Warrant, the Company shall at all times (a) have
authorized and in reserve, and shall keep available, solely for issuance and
delivery upon the exercise of this Warrant, the shares of the Common Stock and
other securities and properties as from time to time shall be receivable upon
the exercise of this Warrant, free and clear of all restrictions on sale or
transfer, other than under Federal or state securities laws, and free and clear
of all preemptive rights and rights of first refusal and (b) use its best
efforts to keep the Warrant Shares authorized for listing on the Nasdaq
National Market, the Nasdaq SmallCap Market or any national securities exchange
on which the Company's Common Stock is traded.





                                       2

3.     PROTECTION AGAINST DILUTION.

       (a)    If, at any time or from time to time after the date of this
Warrant, the Company shall issue or distribute to any holder of shares of
Common Stock evidence of its indebtedness, any other securities of the Company
or any cash, property or other assets (excluding a subdivision, combination or
reclassification, or dividend or distribution payable in shares of Common
Stock, referred to in Section 3(b), and also excluding cash dividends or cash
distributions paid out of net profits legally available therefor in the full
amount thereof (any such non-excluded event being herein called a "SPECIAL
DIVIDEND")), the Per Share Warrant Price shall be adjusted by multiplying the
Per Share Warrant Price then in effect by a fraction, the numerator of which
shall be the then Current Market Price in effect on the record date of such
issuance or distribution less the fair market value (as determined in good
faith by the Company's board of directors) of the evidence of indebtedness,
cash, securities or property, or other assets issued or distributed in such
Special Dividend applicable to one share of Common Stock and the denominator of
which shall be the then Current Market Price in effect on the record date of
such issuance or distribution.  An adjustment made pursuant to this Subsection
3(a) shall become effective immediately after the record date of any such
Special Dividend.

       (b)    In case the Company shall hereafter (i) pay a dividend or make a
distribution to any holder of its capital stock in shares of Common Stock, (ii)
subdivide its outstanding shares of Common Stock into a greater number of
shares, (iii) combine its outstanding shares of Common Stock into a smaller
number of shares or (iv) issue by reclassification of its Common Stock any
shares of capital stock of the Company, the Per Share Warrant Price shall be
adjusted to be equal to a fraction, the numerator of which shall be the
Aggregate Warrant Price and the denominator of which shall be the number of
shares of Common Stock or other capital stock of the Company that the Holder
would have owned immediately following such action had such Warrant been
exercised immediately prior thereto.  An adjustment made pursuant to this
Subsection 3(b) shall become effective immediately after the record date in the
case of a dividend or distribution, and shall become effective immediately
after the effective date in the case of a subdivision, combination or
reclassification.

       (c)    Except as provided in Subsections 3(a) and 3(d), in case the
Company shall hereafter issue or sell any Common Stock, any securities
convertible into Common Stock, any rights, options or warrants to purchase or
otherwise receive an issuance of Common Stock or any securities convertible
into, or exercisable or exchangeable for, Common Stock, in each case for a
price per share or entitling the holders thereof to purchase Common Stock at a
price per share (determined by dividing (i) the total amount, if any, received
or receivable by the Company in consideration of the issuance or sale of such
securities plus the total consideration, if any, payable to the Company upon
exercise thereof (the "TOTAL CONSIDERATION") by (ii) the number of additional
shares of Common Stock issued, sold or issuable upon exercise of such
securities) that is less than either the then Current Market Price in effect on
the date of such issuance or sale or the Per Share Warrant Price, then the Per
Share Warrant Price shall be adjusted as of the date of such issuance or sale
by multiplying the Per Share Warrant Price then in effect by a fraction, the
numerator of which shall be (x) the sum of (A) the number of shares of Common
Stock outstanding on the record date of such issuance or sale plus (B) the
Total Consideration divided by the Current Market Price or the current Per
Share Warrant Price, whichever is greater, and the denominator of which shall
be (y) the number of shares of Common Stock outstanding on the record date of
such issuance or sale plus the maximum number of additional shares of Common
Stock issued, sold or issuable upon exercise or conversion of such securities.

       (d)    No adjustment in the Per Share Warrant Price shall be required in
the case of the issuance by the Company of Common Stock (i) pursuant to the
exercise of any warrant; (ii) pursuant to the exercise of any stock options or
warrants currently outstanding or securities issued after the date hereof,
which may be approved by the Company's board of directors pursuant to any
Company benefit plan or exercised, under any employee benefit plan of the
Company to officers, directors, consultants or employees, but only with respect
to such warrants or stock options as are exercisable at prices no lower than
the closing bid price of the Common Stock as of the date of grant thereof.





                                       3
   5
       (e)    In case of any capital reorganization or reclassification, or any
consolidation or merger to which the Company is a party other than a merger or
consolidation in which the Company is the continuing corporation, or in case of
any sale or conveyance to another entity of the property of the Company as an
entirety or substantially as a entirety, or in the case of any statutory
exchange of securities with another corporation (including any exchange
effected in connection with a merger of a third corporation into the Company),
the Holder of this Warrant shall have the right thereafter to receive on the
exercise of this Warrant the kind and amount of securities, cash or other
property which the Holder would have owned or have been entitled to receive
immediately after such reorganization, reclassification, consolidation, merger,
statutory exchange, sale or conveyance had this Warrant been exercised
immediately prior to the effective date of such reorganization,
reclassification, consolidation, merger, statutory exchange, sale or conveyance
and in any such case, if necessary, appropriate adjustment shall be made in the
application of the provisions set forth in this Section 3 with respect to the
rights and interests thereafter of the Holder of this Warrant to the end that
the provisions set forth in this Section 3 shall thereafter correspondingly be
made applicable, as nearly as may reasonably be, in relation to any shares of
stock or other securities or property thereafter deliverable on the exercise of
this Warrant.  The above provisions of this Section 3(e) shall similarly apply
to successive reorganizations, reclassifications, consolidations, mergers,
statutory exchanges, sales or conveyances.  The Company shall require the
issuer of any shares of stock or other securities or property thereafter
deliverable on the exercise of this Warrant to be responsible for all of the
agreements and obligations of the Company hereunder.  Notice of any such
reorganization, reclassification, consolidation, merger, statutory exchange,
sale or conveyance and of said provisions so proposed to be made, shall be
mailed to the Holders of the Warrants not less than thirty (30) days prior to
such event.  A sale of all or substantially all of the assets of the Company
for a consideration consisting primarily of securities shall be deemed a
consolidation or merger for the foregoing purposes.

       (f)    No adjustment in the Per Share Warrant Price shall be required
unless such adjustment would require an increase or decrease of at least $0.05
per share of Common Stock; provided, however, that any adjustments which by
reason of this Subsection 3(g) are not required to be made shall be carried
forward and taken into account in any subsequent adjustment; provided, further,
however, that adjustments shall be required and made in accordance with the
provisions of this Section 3 (other than this Subsection 3(g)) not later than
such time as may be required in order to preserve the tax-free nature of a
distribution to the Holder of this Warrant or Common Stock issuable upon the
exercise hereof.  All calculations under this Section 3 shall be made to the
nearest cent or to the nearest 1/100th of a share, as the case may be.
Anything in this Section 3 to the contrary notwithstanding, the Company shall
be entitled to make such reductions in the Per Share Warrant Price, in addition
to those required by this Section 3, as it in its discretion shall deem to be
advisable in order that any stock dividend, subdivision of shares or
distribution of rights to purchase stock or securities convertible or
exchangeable for stock hereafter made by the Company to its stockholders shall
not be taxable.

       (g)    Whenever the Per Share Warrant Price is adjusted as provided in
this Section 3 and Section 4 and upon any modification of the rights of a
Holder of Warrants in accordance with this Section 3, the Company shall
promptly prepare a brief statement of the facts requiring such adjustment or
modification and the manner of computing the same and cause copies of such
certificate to be mailed to the Holders of the Warrants.  The Company may, but
shall not be obligated to unless requested by a Majority of the Holders,
obtain, at its expense, a certificate of a firm of independent public
accountants of recognized standing selected by the board of directors (who may
be the regular auditors of the Company) setting forth the Per Share Warrant
Price and the number of Warrant Shares in effect after such adjustment or the
effect of such modification, a brief statement of the facts requiring such
adjustment or modification and the manner of computing the same and cause
copies of such certificate to be mailed to the Holders of the Warrants.

       (h)    If the board of directors of the Company shall declare any
dividend or other distribution with respect to the Common Stock other than a
cash distribution out of earned surplus, the Company shall mail notice thereof
to the Holders of the Warrants not less than ten (10) days prior to the record
date fixed for determining stockholders entitled to participate in such
dividend or other distribution.





                                       4
   6
       (i)    If, as a result of an adjustment made pursuant to this Section 3,
the Holder of any Warrant thereafter surrendered for exercise shall become
entitled to receive shares of two or more classes of capital stock or shares of
Common Stock and other capital stock of the Company, the board of directors
(whose determination shall be conclusive and shall be described in a written
notice to the Holder of any Warrant promptly after such adjustment) shall
determine the allocation of the adjusted Per Share Warrant Price between or
among shares or such classes of capital stock or shares of Common Stock and
other capital stock.

       (j)    Upon the expiration of any rights, options, warrants or
conversion privileges with respect to the issuance of which an adjustment to
the Per Share Warrant Price had been made, if such shall not have been
exercised, the number of Warrant Shares purchasable upon exercise of this
Warrant, to the extent this Warrant has not then been exercised, shall, upon
such expiration, be readjusted and shall thereafter be such as they would have
been had they been originally adjusted (or had the original adjustment not been
required, as the case may be) on the basis of (A) the fact that Common Stock,
if any, actually issued or sold upon the exercise of such rights, options,
warrants or conversion privileges, and (B) the fact that such shares of Common
Stock, if any, were issued or sold for the consideration actually received by
the Company upon such exercise plus the consideration, if any, actually
received by the Company for the issuance, sale or grant of all such rights,
options, warrants or conversion privileges whether or not exercised; provided,
however, that no such readjustment shall have the effect of decreasing the
number of Warrant Shares purchasable upon exercise of this Warrant by an amount
in excess of the amount of the adjustment initially made in respect of the
issuance, sale or grant of such rights, options, warrants or conversion
privileges.

       (l)    In case any event shall occur as to which the other provisions of
this Section 3 are not strictly applicable but as to which the failure to make
any adjustment would not fairly protect the purchase rights represented by this
Warrant in accordance with the essential intent and principles hereof then, in
each such case, the Holders of Warrants representing the right to purchase a
majority of the Warrant Shares subject to all outstanding Warrants may appoint
a firm of independent public accountants of recognized national standing
reasonably acceptable to the Company, which shall give their opinion as to the
adjustment, if any, on a basis consistent with the essential intent and
principles established herein, necessary to preserve the purchase rights
represented by the Warrants.  Upon receipt of such opinion, the Company will
promptly mail a copy thereof to the Holder of this Warrant and shall make the
adjustments described therein.  The fees and expenses of such independent
public accountants shall be borne by the Company.

4.     RESET OF PER SHARE WARRANT PRICE; ISSUANCE OF ADDITIONAL WARRANT SHARES.


       (a)    In the event (a "Reset Event") that on the date that is 12 months
from the issuance date of this Warrant (the "Reset Date"), the average closing
bid price of the Common Stock for the 20 trading days immediately preceding the
Reset Date (the "Reset Trading Price") is less than the Per Share Warrant Price
then in effect then:

              (i)    the Per Share Warrant Price shall be reset and adjusted to
       equal the greater of (A) the Reset Trading Price and (B) fifty percent
       (50%) of the Per Share Warrant Price then in effect (such Per Share
       Warrant price as reset is referred to as the "Reset Price"); and

              (ii)   the number of Warrant Shares deliverable upon exercise of
       this Warrant shall be adjusted by dividing the Aggregate Warrant Price by
       the Reset Price.

       (b)    Upon the occurrence of a Reset Event, the Company shall inform
the Holder by written notice (the "Reset Notice") at the address set forth in
Section 10(b) (i) that a Reset Event has occurred, (ii) the Reset Price and
(iii) the number of Warrant Shares, as adjusted in accordance with Section
4(a)(ii), issuable upon exercise of this Warrant.  The Company may request in
such Reset Notice that the Holder surrender this Warrant to the Company at the
address set forth in Section 10(a) for cancellation and issuance of a new
Warrant in the name of the Holder setting forth (x) the adjusted Per Share
Warrant Price and (y) the adjusted number of Warrant Shares issuable upon
exercise of this Warrant.





                                       5

   7

5.     PER SHARE WARRANT PRICE FLOOR; CASH PAYOUT. For purposes of this
Warrant, "PER SHARE WARRANT PRICE FLOOR" shall mean 50% of the average Closing
Bid Price (as defined in the Purchase Agreement") of the Common Stock for the
five (5) trading days immediately prior to the Closing Date (as defined in the
Agreement). In the event that (a) the Common Stock trades at less than the Per
Share Warrant Price Floor on 60 or more trading days in any 12-month period
(irrespective of whether such trading days are consecutive), and (b) the Per
Share Warrant Price applicable to any exercise of Warrants that is effective as
of a date not later than the 12-month anniversary of the earliest of such 60
days is less than the Per Share Warrant Price Floor, the Company shall either
effect such exercise at the applicable Per Share Warrant Price or pay to the
holder of such Warrants, in cash, an amount (the "Cash Pay-Out Amount") equal
to the product of (x) the number of shares of Common Stock that would otherwise
be issuable upon such exercise and (y) the highest closing trade price for the
Common Stock during the period commencing on the date of the request for
exercise and ending on the day immediately prior to the date of payment of the
Cash Pay-Out Amount.

6.     FULLY PAID STOCK; TAXES.  The shares of the Common Stock represented by
each and every certificate for Warrant Shares delivered on the exercise of this
Warrant shall at the time of such delivery, be duly authorized, validly issued
and outstanding, fully paid and nonassessable, and not subject to preemptive
rights or rights of first refusal, and the Company will take all such actions
as may be necessary to assure that the par value, if any, per share of the
Common Stock is at all times equal to or less than the then Per Share Warrant
Price.  The Company will pay, when due and payable, any and all Federal and
state stamp, original issue or similar taxes which may be payable in respect of
the issue of any Warrant Share or any certificate thereof to the extent
required because of the issuance by the Company of such security.

7.     REGISTRATION UNDER SECURITIES ACT OF 1933.  (a)  The Holder shall have
the right to participate in the registration rights granted to Holders of
Registrable Securities (as defined in the Purchase Agreement") with respect to
the Warrant Shares, as adjusted.  By acceptance of this Warrant, the Holder
agrees to comply with the provisions of Article 8 of the Purchase Agreement to
same extent as if it were a party thereto.

       (b)    Until all of the Warrant Shares, including additional Warrant
Shares issuable pursuant to Section 4 hereof, have been sold under a
registration statement declared effective by the Securities and Exchange
Commission or pursuant to Rule 144, the Company shall use its reasonable best
efforts to file with the Securities and Exchange Commission all current reports
and the information as may be necessary to enable the Holder to effect sales of
its shares in reliance upon Rule 144 promulgated under the Securities Act of
1933, as amended (the "Act").

8.     MANDATORY EXERCISE.  (a) At any time on or after the Reset Date, the
Company, at its option, may cause this Warrant to be exercised in whole into
fully paid and nonassessable shares of Common Stock if the closing price of the
Common Stock shall have exceeded 300% of the then applicable Per Share Warrant
Price for at least 20 trading days in the 30 consecutive trading day period
ending on the date on which the Company provides the Holder with notice in
accordance with Section 7(b) below.  Any Warrants so converted shall be treated
as having been surrendered by the Holder for exercise pursuant to Section 1 on
the date of such mandatory exercise (unless previously converted at the option
of the Holder).

       (b)    Not more than 60 nor less than 20 days prior to the date of any
such mandatory exercise, notice by first class mail, postage prepaid, shall be
given to the Holder, addressed to the Holder at the addresses set forth in
Section 10(b).  Each such notice shall specify the date fixed for exercise, the
place or places for surrender of Warrants and the Per Share Warrant Price then
in effect.

       (c)    The "closing price" for each trading day shall be the reported
last sales price regular way or, in case no such reported sale takes place on
such day, the average of the reported closing bid and asked prices regular way,
in either case on the NASDAQ or, if the Common Stock is not quoted on NASDAQ,
on the principal national securities exchange on which the Common Stock is
listed or admitted to trading (based on the aggregate dollar value of all
securities listed or admitted to trading) or, if not listed or admitted to
trading on any national securities exchange or quoted on NASDAQ, the average of
the closing





                                       6

bid and asked prices in the over-the-counter market as furnished by any NASD
member firm selected from time to time by the Corporation for that purpose, or,
if such prices are not available, the fair market value set by, or in a manner
established by, the Board of Directors of the Corporation in good faith.

9.     INVESTMENT INTENT; LIMITED TRANSFERABILITY.

       (a)  The Holder represents, by accepting this Warrant, that it
understands that this Warrant and any securities obtainable upon exercise of
this Warrant have not been registered for sale under Federal or state
securities laws and are being offered and sold to the Holder pursuant to one or
more exemptions from the registration requirements of such securities laws.  In
the absence of an effective registration of such securities or an exemption
therefrom, any certificates for such securities shall bear the legend set forth
on the first page hereof.  The Holder understands that it must bear the
economic risk of its investment in this Warrant and any securities obtainable
upon exercise of this Warrant for an indefinite period of time, as this Warrant
and such securities have not been registered under Federal or state securities
laws and therefore cannot be sold unless subsequently registered under such
laws, unless an exemption from such registration is available.

       (b)  The Holder, by its acceptance of this Warrant, represents to the
Company that it is acquiring this Warrant and will acquire any securities
obtainable upon exercise of this Warrant for its own account for investment and
not with a view to, or for sale in connection with, any distribution thereof in
violation of the Act.  The Holder agrees that this Warrant and any such
securities will not be sold or otherwise transferred unless (i) a registration
statement with respect to such transfer is effective under the Act and any
applicable state securities laws or (ii) such sale or transfer is made pursuant
to one or more exemptions from the Act.

       (c) In addition to the limitations set forth in Section 1(a) hereon,
