THIS WARRANT HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED OR ANY STATE SECURITIES LAWS. NO SALE OR DISPOSITION MAY BE EFFECTED
WITHOUT (i) EFFECTIVE REGISTRATION STATEMENTS RELATED THERETO, (ii) AN OPINION
OF COUNSEL OR OTHER EVIDENCE, REASONABLY SATISFACTORY TO THE COMPANY, THAT SUCH

APPROPRIATE GOVERNMENTAL AUTHORITIES, OR (iv) OTHERWISE COMPLYING WITH THE
PROVISIONS OF SECTION 7 OF THIS WARRANT.

                              JLM INDUSTRIES, INC.

                           WARRANT TO PURCHASE SHARES
                                 OF COMMON STOCK

      THIS CERTIFIES THAT, for value received, GATX CAPITAL CORPORATION. and its
assignees are entitled to subscribe for and purchase 155,109 shares of the fully
paid and nonassessable Common Stock (as adjusted pursuant to Section 4 hereof,
the "Shares") of JLM Industries, Inc., a Delaware corporation (the "Company"),
at the price of $2.30 per share (such price and such other price as shall
result, from time to time, from the adjustments specified in Section 4 hereof is
herein referred to as the "Warrant Price"), subject to the provisions and upon
the terms and conditions hereinafter set forth. As used herein, (a) the term
"Date of Grant" shall mean June 21, 2001 and (b) the term "Other Warrants" shall
mean any other warrants issued by the Company in connection with the transaction
with respect to which this Warrant was issued, and any warrant issued upon
transfer or partial exercise of this Warrant. The term "Warrant" as used herein
shall be deemed to include Other Warrants unless the context clearly requires
otherwise.

      1. TERM. The purchase right represented by this Warrant is exercisable, in
whole or in part, at any time and from time to time from the Date of Grant
through June 21, 2011.

      2. METHOD OF EXERCISE; PAYMENT; ISSUANCE OF NEW WARRANT. Subject to
Section 1 hereof, the purchase right represented by this Warrant may be
exercised by the holder hereof, in whole or in part and from time to time, at
the election of the holder hereof, by (a) the surrender of this Warrant (with
the notice of exercise substantially in the form attached hereto as Exhibit A-1
duly completed and executed) at the principal office of the Company and by the
payment to the Company, by certified or bank check, or by wire transfer to an
account designated by the Company (a "Wire Transfer") of an amount equal to the
then applicable Warrant Price multiplied by the number of Shares then being
purchased; (b) if in connection with a registered public offering of the
Company's securities, the surrender of this Warrant (with the notice of exercise
form attached hereto as Exhibit A-2 duly completed and executed) at the
principal office of the Company together with notice of arrangements reasonably
satisfactory to the Company for payment to the Company either by certified or
bank check or by Wire Transfer from the proceeds of the sale of shares to be
sold by the holder in such public offering of an amount equal to the then
applicable Warrant Price per share multiplied by the number of Shares then being
purchased; or (c) exercise of the "net issuance" right provided for in Section
10.2 hereof. The person or persons in whose name(s) any certificate(s)
representing the Shares shall be issuable upon exercise of this Warrant shall be
deemed to have become the holder(s) of record of, and shall be treated for all
purposes as the record holder(s) of, the shares represented thereby (and such
shares shall be deemed to have been issued) immediately prior to the close of
business on the date or dates upon which this Warrant is exercised. In the event
of any exercise of the rights represented by this Warrant, certificates for the
shares of stock so purchased shall be delivered to the

                                       1
<PAGE>

holder hereof as soon as possible and in any event within thirty (30) days after
such exercise and, unless this Warrant has been fully exercised or expired, a
new Warrant representing the portion of the Shares, if any, with respect to
which this Warrant shall not then have been exercised shall also be issued to
the holder hereof as soon as possible and in any event within such thirty-day
period.

      3. STOCK FULLY PAID; RESERVATION OF SHARES. All Shares that may be issued
upon the exercise of the rights represented by this Warrant will, upon issuance
pursuant to the terms and conditions herein, be fully paid and nonassessable,
and free from all taxes, liens and charges with respect to the issue thereof.
During the period within which the rights represented by this Warrant may be
exercised, the Company will at all times have authorized, and reserved for the
purpose of the issue upon exercise of the purchase rights evidenced by this
Warrant, a sufficient number of shares of its Common Stock to provide for the
exercise of the rights represented by this Warrant.

      4. ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES. The number and kind
of securities purchasable upon the exercise of this Warrant and the Warrant
Price shall be subject to adjustment from time to time upon the occurrence of
certain events, as follows:

      (a) RECLASSIFICATION OR MERGER. In case of any reclassification or change
of securities of the class issuable upon exercise of this Warrant (other than a
change in par value, or from par value to no par value, or from no par value to
par value, or as a result of a subdivision or combination), or in case of any
merger of the Company with or into another corporation (other than a merger with
another corporation in which the Company is the surviving corporation and which
does not result in any reclassification or change of outstanding securities
issuable upon exercise of this Warrant), or in case of any sale of all or
substantially all of the assets of the Company, the holder of this Warrant shall
be entitled, upon the exercise hereof at any time after consummation of any of
the foregoing events to the extent this Warrant is not exercised before such
event or redeemed in connection with such event, to receive, at a total purchase
price not to exceed that payable upon the exercise of the unexercised portion of
this Warrant, and in lieu of the shares of Common Stock theretofore issuable
upon exercise of this Warrant, the kind and amount of shares of stock, other
securities, money and property receivable upon such reclassification, change,
merger, or sale of all or substantially all of the assets of the Company by a
holder of the number of shares of Common Stock then purchasable under this
Warrant.

      (b) SUBDIVISION OR COMBINATION OF SHARES. If the Company at any time while
this Warrant remains outstanding and unexpired shall subdivide its outstanding
shares of Common Stock, the Warrant Price shall be proportionately decreased to
reflect the increase in the total number of shares of Common Stock outstanding
as a result of such subdivision (and the number of Shares issuable hereunder
shall be proportionately increased pursuant to Section 4(f) below). If the
Company at any time while this Warrant remains outstanding and unexpired shall
combine its outstanding shares of Common Stock, the Warrant Price shall be
proportionately increased to reflect the reduction in the total number of shares
of Common Stock outstanding as a result of such combination (and the number of
Shares issuable hereunder shall be proportionately decreased pursuant to Section
4(f) below).

      (c) STOCK DIVIDENDS AND OTHER DISTRIBUTIONS. If the Company at any time
while this Warrant is outstanding and unexpired shall (i) pay a dividend with
respect to Common Stock payable in Common Stock, then the Warrant Price shall be
adjusted, from and after the date of determination of shareholders entitled to
receive such dividend or distribution, to that price determined by multiplying
the Warrant Price in effect immediately prior to such date of determination by a
fraction (A) the numerator of which shall be the total number of shares of
Common Stock outstanding immediately prior to such dividend or

                                       -2-
<PAGE>

distribution, and (B) the denominator of which shall be the total number of
shares of Common Stock outstanding immediately after such dividend or
distribution; or (ii) make any other distribution with respect to Common Stock
(except any distribution specifically provided for in Sections 4(a) and 4(b)),
then, in each such case, provision shall be made by the Company such that the
holder of this Warrant shall receive upon exercise of this Warrant a
proportionate share of any such dividend or distribution as though it were the
holder of the Common Stock as of the record date fixed for the determination of
the shareholders of the Company entitled to receive such dividend or
distribution.

      (d)   ISSUANCE OF ADDITIONAL SHARES OF COMMON STOCK. If the Company, at
any time while this Warrant is outstanding, shall issue any Additional Shares of
Common Stock (otherwise than as provided in the foregoing subsections (a)
through (c) of this Section 4), at a price per share less than the Warrant Price
then in effect or without consideration, then the Warrant Price upon each such
issuance shall be adjusted to that price (rounded to the nearest cent)
determined by multiplying the Warrant Price then in effect by a fraction:

            (i) the numerator of which shall be equal to the sum of (A) the
number of shares of Common Stock outstanding immediately prior to the issuance
of such Additional Shares of Common Stock plus (B) the number of shares of
Common Stock (rounded to the nearest whole share) which the aggregate
consideration for the total number of such Additional Shares of Common Stock so
issued would purchase at a price per share equal to the Warrant Price then in
effect, and

            (ii) the denominator of which shall be equal to the number of shares
of Common Stock outstanding immediately after the issuance of such Additional
Shares of Common Stock.

The provisions of this subsection (d) shall not apply under any of the
circumstances for which an adjustment is provided in subsection (a), (b) or (c)
of this Section 4. No adjustment of the Warrant Price shall be made under this
subsection (d) upon the issuance of any Additional Shares of Common Stock which
are issued pursuant to any Common Stock Equivalent if upon the issuance of such
Common Stock Equivalent (x) any adjustment shall have been made pursuant to
subsection (e) of this Section 4 or (y) no adjustment was required pursuant to
subsection (e) of this Section 4. No adjustment of the Warrant Price shall be
made under this subsection (d) in an amount (A) that results in the Warrant
Price being less than $1.15 per share or (B) less than $.01 per share, but any
such lesser adjustment shall be carried forward and shall be made at the time
and together with the next subsequent adjustment, if any, which together with
any adjustments so carried forward shall amount to $.01 per share or more,
provided that upon any adjustment of the Warrant Price as a result of any
dividend or distribution payable in Common Stock or Convertible Securities or
the reclassification, subdivision or combination of Common Stock into a greater
or smaller number of shares, the foregoing figure of $.01 per share (or such
figure as last adjusted) shall be adjusted (to the nearest one-half cent) in
proportion to the adjustment in the Warrant Price.

      (e)   ISSUANCE OF COMMON STOCK EQUIVALENTS. If the Company, at any time
while this Warrant is outstanding, shall issue any Common Stock Equivalent and
the price per share for which Additional Shares of Common Stock may be issuable
thereafter pursuant to such Common Stock Equivalent shall be less than the
Warrant Price then in effect, or if, after any such issuance of Common Stock
Equivalents, the price per share for which Additional Shares of Common Stock may
be issuable thereafter is amended or adjusted, and such price as so amended
shall be less than the Warrant Price in effect at the time of such amendment,
then the Warrant Price upon each such issuance or amendment shall be adjusted as
provided in the first sentence of subsection (d) of this Section 4 on the basis
that (1) the maximum number of Additional Shares of Common Stock issuable
pursuant to all such Common Stock Equivalents shall be

                                      -3-
<PAGE>

deemed to have been issued (whether or not such Common Stock Equivalents are
actually then exercisable, convertible or exchangeable in whole or in part) as
of the earlier of (A) the date of which the Company shall enter into a firm
contract for the issuance of such Common Stock Equivalent, or (B) the date of
actual issuance of such Common Stock Equivalent, and (2) the aggregate
consideration for such maximum number of Additional Shares of Common Stock shall
be deemed to be the minimum consideration received or receivable by the Company
for the issuance of such Additional Shares of Common Stock pursuant to such
Common Stock Equivalent. No adjustment of the Warrant Price shall be made under
this subsection (e) (A) upon the issuance of any Convertible Security which is
issued pursuant to the exercise of any warrants or other subscription or
purchase rights therefor, if any adjustment shall previously have been made in
the Warrant Price then in effect upon the issuance of such warrants or other
rights pursuant to this subsection (e) or (B) that results in the Warrant Price
being less than $1.15 per share.

      (f)   ADJUSTMENT OF NUMBER OF SHARES. Upon each adjustment in the Warrant
Price, the number of Shares purchasable hereunder shall be adjusted, to the
nearest whole share, to the product obtained by multiplying the number of Shares
purchasable immediately prior to such adjustment in the Warrant Price by a
fraction, the numerator of which shall be the Warrant Price immediately prior to
such adjustment and the denominator of which shall be the Warrant Price
immediately thereafter.

      (g)   DEFINITIONS.

            (iii) "Convertible Securities" means evidences of indebtedness,

      7.    COMPLIANCE WITH ACT; DISPOSITION OF WARRANT OR SHARES OF COMMON
STOCK.

      (a)   COMPLIANCE WITH ACT. The holder of this Warrant, by acceptance
hereof, agrees that this Warrant, and the Shares to be issued upon exercise
hereof are being acquired for investment and that such holder will not offer,
sell or otherwise dispose of this Warrant, or any Shares except under
circumstances which will not result in a violation of the Act or any applicable
state securities laws. Upon exercise of this Warrant, unless the Shares being
acquired are registered under the Act and any applicable state securities laws
or an exemption from such registration is available, the holder hereof agrees
that the Shares so purchased are being acquired for investment and not with a
view toward distribution or resale in violation of the Act. This Warrant and all
Shares issued upon exercise of this Warrant (unless registered under the Act and
any applicable state securities laws) shall be stamped or imprinted with a
legend in substantially the following form:

      "THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
      SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS. NO SALE
      OR DISPOSITION MAY BE EFFECTED WITHOUT (i) EFFECTIVE REGISTRATION
      STATEMENTS RELATED THERETO, (ii) AN OPINION OF COUNSEL OR OTHER EVIDENCE,
      REASONABLY SATISFACTORY TO THE COMPANY, THAT SUCH REGISTRATIONS ARE NOT
      REQUIRED, (iii) RECEIPT OF NO-ACTION LETTERS FROM THE APPROPRIATE
      GOVERNMENTAL AUTHORITIES, OR (iv) OTHERWISE COMPLYING WITH THE PROVISIONS
      OF SECTION 7 OF THE WARRANT UNDER WHICH THESE SECURITIES WERE ISSUED,
      DIRECTLY OR INDIRECTLY."

Said legend shall be removed by the Company, upon the request of a holder, at
such time as the restrictions on the transfer of the applicable security shall
have terminated. In addition, in connection with the issuance of this Warrant,
the holder specifically represents to the Company by acceptance of this Warrant
as follows:

      (1) The holder is aware of the Company's business affairs and financial
condition, and has acquired information about the Company sufficient to reach an
informed and knowledgeable decision to acquire this Warrant. The holder is
acquiring this Warrant for its own account for investment purposes only and not
with a view to, or for the resale in connection with, any "distribution" thereof
in violation of the Act.

      (2) The holder understands that this Warrant has not been registered under
the Act in reliance upon a specific exemption therefrom, which exemption depends
upon, among other things, the bona fide nature of the holder's investment intent
as expressed herein.

      (3) The holder further understands that this Warrant must be held
indefinitely unless subsequently registered under the Act and qualified under
any applicable state securities laws, or unless exemptions from registration and
qualification are otherwise available. The holder is aware of the provisions of
Rule 144, promulgated under the Act.

      (4) The holder is an "accredited investor" as such term is defined in Rule
501 of Regulation D promulgated under the Act.

                                      -5-
<PAGE>

      (b) DISPOSITION OF WARRANT OR SHARES. With respect to any offer, sale or
other disposition of this Warrant or any Shares acquired pursuant to the
exercise of this Warrant prior to registration of such Warrant or Shares, the
holder hereof agrees to give written notice to the Company prior thereto,
describing briefly the manner thereof, together with a written opinion of such
holder's counsel, or other evidence, if reasonably satisfactory to the Company,
to the effect that such offer, sale or other disposition may be effected without
registration or qualification (under the Act as then in effect or any federal or
state securities law then in effect) of this Warrant or the Shares and
indicating whether or not under the Act certificates for this Warrant or the
Shares to be sold or otherwise disposed of require any restrictive legend as to
applicable restrictions on transferability in order to ensure compliance with
such law. Upon receiving such written notice and reasonably satisfactory opinion
or other evidence, the Company, as promptly as practicable but no later than
fifteen (15) days after receipt of the written notice, shall notify such holder
that such holder may sell or otherwise dispose of this Warrant or such Shares,
all in accordance with the terms of the notice delivered to the Company. If a
determination has been made pursuant to this Section 7(b) that the opinion of
counsel for the holder or other evidence is not reasonably satisfactory to the
Company, the Company shall so notify the holder promptly with details thereof
after such determination has been made. Notwithstanding the foregoing, this
Warrant or such Shares may, as to such federal laws, be offered, sold or
otherwise disposed of in accordance with Rule 144 or 144A under the Act,
provided that the Company shall have been furnished with such information as the
Company may reasonably request to provide a reasonable assurance that the
provisions of Rule 144 or 144A have been satisfied. Each certificate
representing this Warrant or the Shares thus transferred (except a transfer
pursuant to Rule 144 or 144A) shall bear a legend as to the applicable
restrictions on transferability in order to ensure compliance with such laws,
unless in the aforesaid opinion of counsel for the holder, such legend is not
required in order to ensure compliance with such laws. The Company may issue
stop transfer instructions to its transfer agent in connection with such
restrictions.

       (d) APPLICABILITY OF RESTRICTIONS. Neither any restrictions of any legend
described in this Warrant nor the requirements of Section 7(b) above shall apply
(i) when the Shares shall have been registered under the Securities Act of 1933
(in which case, the holder of this Warrant will be entitled to receive from the
Company or its transfer agent, without expense, a new Warrant, or, in the case
of Shares, new stock certificates, not bearing the legend required by Section
7(a) above) or (ii) to any transfer or grant of a security interest in, this
Warrant (or the Common Stock obtainable upon exercise thereof) or any part
hereof (a) to a partner of the holder if the holder is a partnership or to a
member of the holder if the holder is a limited liability company, (b) to a
partnership of which the holder is a partner or to a limited liability company
of which the holder is a member, or (c) to any affiliate of the holder if the
holder is a corporation; PROVIDED, HOWEVER, in any such transfer, if applicable,
the transferee shall on the Company's request agree in writing to be bound by
the terms of this Warrant as if an original holder hereof.

      8. RIGHTS AS SHAREHOLDERS; INFORMATION. No holder of this Warrant, as
such, shall be entitled to vote or receive dividends or be deemed the holder of
Shares, nor shall anything contained herein be construed to confer upon the
holder of this Warrant, as such, any of the rights of a shareholder of the
Company or any right to vote for the election of directors or upon any matter
submitted to shareholders at any meeting thereof, or to receive notice of
meetings, or to receive dividends or subscription rights or otherwise until this
Warrant shall have been exercised and the Shares purchasable upon the exercise
hereof shall have become deliverable, as provided herein. Notwithstanding the
foregoing, the Company will transmit to the holder of this Warrant such
information, documents and reports as are generally distributed to the holders
of any class or series of the securities of the Company concurrently with the
distribution thereof to the shareholders.

                                      -6-

      9.    REGISTRATION RIGHTS. Notwithstanding Section 8 of the Registration
Rights Agreement (as defined below), the Company covenants to include the Shares
in its shelf registration statement on Form S-3 to be filed with the Securities
and Exchange Commission by the Company pursuant to the Registration Rights
Agreement dated June 7, 2001, among the Company and certain investors of the
Company, a copy of which is attached as Exhibit C (the "Registration Rights
Agreement"). The Company grants to the holder of this Warrant all of the rights
and privileges of a "Holder" under the Registration Rights Agreement, including
without limitation (i) the inclusion of the Shares in the definition of
"Registrable Securities" under the Registration Rights Agreement and the
registration of the Shares under Sections 2 and 3 of the Registration Rights
Agreement, (ii) reimbursement for expenses under Section 4 of the Registration
Rights Agreement, and (iii) the rights and obligations to indemnification and
contribution under Section 6 of the Registration Rights Agreement. The Company
has obtained a waiver of the applicable restrictions in the Registration Rights
Agreement with respect to the rights granted to the holder in this Section 9.

      10.   ADDITIONAL RIGHTS.

      10.1  ACQUISITION TRANSACTIONS. The Company shall provide the holder of
this Warrant with at least twenty (20) days' written notice prior to closing
thereof of the terms and conditions of any of the following transactions (to the
extent the Company has notice thereof): (i) the sale, lease, exchange,
conveyance or other disposition of all or substantially all of the Company's
property or business, or (ii) its merger into or consolidation with any other
corporation (other than a wholly-owned subsidiary of the Company), or (iii) any
transaction (including a merger or other reorganization) or series of related
transactions, in which more than 50% of the voting power of the Company is
disposed of.

      10.2  RIGHT TO CONVERT WARRANT INTO STOCK:  NET ISSUANCE.

      (a)   RIGHT TO CONVERT. In addition to and without limiting the rights of
the holder under the terms of this Warrant, the holder shall have the right to
convert this Warrant or any portion thereof (the "Conversion Right") into shares
of Common Stock as provided in this Section 10.2 at any time or from time to
time during the term of this Warrant. Upon exercise of the Conversion Right with
respect to a particular number of shares subject to this Warrant (the "Converted
Warrant Shares"), the Company shall deliver to the holder (without payment by
the holder of any exercise price or any cash or other consideration) that number
of shares of fully paid and nonassessable Common Stock as is determined
according to the following formula:

                        X =   B - A
                            ---------
                                Y

      Where:      X  =  the number of shares of Common Stock that shall be
            issued to the holder

                  Y  =  the fair market value of one share of  Common Stock

                  A = the aggregate Warrant Price of the specified number of
            Converted Warrant Shares immediately prior to the exercise of the
            Conversion Right (I.E., the number of Converted Warrant Shares
            MULTIPLIED BY the Warrant Price)

                                      -7-
<PAGE>

                  B = the aggregate fair market value of the specified number of
            Converted Warrant Shares (I.E. the number of Converted Warrant
            Shares MULTIPLIED BY the fair market value of one Converted Warrant
            Share)

No fractional shares shall be issuable upon exercise of the Conversion Right,
and, if the number of shares to be issued determined in accordance with the
foregoing formula is other than a whole number, the Company shall pay to the
holder an amount in cash equal to the fair market value of the resulting
fractional share on the Conversion Date (as hereinafter defined). For purposes
of Section 9 of this Warrant, shares issued pursuant to the Conversion Right
shall be treated as if they were issued upon the exercise of this Warrant.

      (b) METHOD OF EXERCISE. The Conversion Right may be exercised by the
holder by the surrender of this Warrant at the principal office of the Company
together with a written statement (which may be in the form of Exhibit A-1 or
Exhibit A-2 hereto) specifying that the holder thereby intends to exercise the
Conversion Right and indicating the number of shares subject to this Warrant
which are being surrendered (referred to in Section 10.2(a) hereof as the
Converted Warrant Shares) in exercise of the Conversion Right. Such conversion
shall be effective upon receipt by the Company of this Warrant together with the
aforesaid written statement, or on such later date as is specified therein (the
"Conversion Date"), and, at the election of the holder hereof, may be made
contingent upon the closing of the sale of the Company's Common Stock to the
public in a public offering pursuant to a Registration Statement under the Act
(a "Public Offering"). Certificates for the shares issuable upon exercise of the
Conversion Right and, if applicable, a new warrant evidencing the balance of the
shares remaining subject to this Warrant, shall be issued as of the Conversion
Date and shall be delivered to the holder within thirty (30) days following the
Conversion Date.

      (c) DETERMINATION OF FAIR MARKET VALUE. For purposes of this Section 10.2,
"fair market value" of a share of Common Stock as of a particular date (the
"Determination Date") shall mean:

                  (i) If the Conversion Right is exercised in connection with
and contingent upon a Public Offering, and if the Company's Registration
Statement relating to such Public Offering ("Registration Statement") has been
declared effective by the Securities and Exchange Commission, then the initial
"Price to Public" specified in the final prospectus with respect to such
offering.

            (ii) If the Conversion Right is not exercised in connection with and
contingent upon a Public Offering, then as follows:

                        (A) If traded on a securities exchange, the fair market
      value of the Common Stock shall be deemed to be the average of the closing
      prices of the Common Stock on such exchange over the five trading days
      immediately prior to the Determination Date;

                        (B) If traded on the NASDAQ Stock Market or other
      over-the-counter system, the fair market value of the Common Stock shall
      be deemed to be the average of the closing bid prices of the Common Stock
      over the five trading days immediately prior to the Determination Date;
      and

                        (C) If there is no public market for the Common Stock,
      then fair market value shall be determined by mutual agreement of the
      holder of this Warrant and the Company.

                                      -8-
<PAGE>

      10.3  EXERCISE PRIOR TO EXPIRATION. To the extent this Warrant is not
previously exercised as to all of the Shares subject hereto, and if the fair
market value of one share of the Common Stock is greater than the Warrant Price
then in effect, this Warrant shall be deemed automatically exercised pursuant to
Section 10.2 above (even if not surrendered) immediately before its expiration.
For purposes of such automatic exercise, the fair market value of one share of
Common Stock upon such expiration shall be determined pursuant to Section
10.2(c). To the extent this Warrant or any portion thereof is deemed
automatically exercised pursuant to this Section 10.3, the Company agrees to
promptly notify the holder hereof of the number of Shares, if any, the holder
hereof is to receive by reason of such automatic exercise.
