Defaults which have occurred under the Credit Agreement and (ii) amend certain
terms and conditions of the Credit Agreement, as more particularly set forth
herein. The Bank has agreed to do so, but only upon the terms and conditions set

in respect of the JLM Domestic Entities, any other guarantor or other person
liable in respect of the Liabilities or any collateral granted to the Bank by

     INTEREST.  The undersigned will pay on demand interest on all amounts due
to the Bank under this Guaranty, or arising under any documents, instruments, or
agreements relating to any collateral securing this Guaranty, from the time the
Bank first demands payment of this Guaranty at a rate equal to the highest rate
chargeable to the JLM Domestic Entities after the earlier of (i) demand, (ii)
maturity, or (iii) the occurrence of any event of default under any instrument,
document or agreement heretofore or hereafter executed by the JLM Domestic
Entities (but in no event higher than the highest rate of interest which under
the circumstances may be charged under applicable law).

     OFFSET.  Any and all deposits or other sums at any time credited by or due
to the undersigned from the Bank or any of its banking or lending affiliates,
and any cash, securities, instruments or other property of the undersigned in
the possession of the Bank, or any of its banking or lending affiliates, whether
for safekeeping or otherwise shall at all times constitute security for all
Liabilities and for any and all obligations of the undersigned to the Bank, now
existing or hereafter arising, and may be applied or set off against such
Liabilities and against the obligations of the undersigned to the Bank
including, without limitation, those arising hereunder, at any time, whether or
not such are then due and whether or not other collateral is then available to
the Bank.

     OBLIGATIONS NOT AFFECTED.  The obligations of the undersigned hereunder
shall not be affected by: any fraudulent, illegal, or improper act by the JLM
Domestic Entities, the undersigned, or any person liable or obligated to the
Bank for or on the Liabilities; any release, discharge, or invalidation, by
operation of law or otherwise, of the Liabilities; or the legal incapacity of
the JLM Domestic Entities, the undersigned, or any other person liable or
obligated to the Bank for or on the Liabilities. Interest and Costs of
Collection shall continue to accrue and shall continue to be deemed Liabilities
guarantied hereby notwithstanding any stay to the enforcement thereof against
the JLM Domestic Entities or disallowance of any claim therefor against the JLM
Domestic Entities.

     INCORPORATION OF ALL DISCUSSIONS.  The within instrument incorporates all
discussions and negotiations the undersigned and the Bank concerning the
guaranty and indemnification provided by the undersigned hereby. No such
discussions or negotiations shall limit, modify, or otherwise affect the
provisions hereof. No provision hereof may be altered, amended, waived,
cancelled or modified, except by a written instrument executed, sealed, and
acknowledged by a duly authorized representative of the Bank.

protest with respect to the Liabilities and this Guaranty; any delay on the part
of the Bank; any right to require the Bank to pursue or to proceed against the
JLM Domestic Entities or any collateral which the Bank might have been granted
to secure the Liabilities or to secure the obligations of the undersigned
hereunder; any benefit of, and any right to participate in, any collateral which
may secure the Liabilities; notice of acceptance of this Guaranty.

following:

          (a)  exercise any rights against the JLM Domestic Entities, by way of
               subrogation reimbursement, indemnity, contribution or otherwise
               (all and singular of which the undersigned hereby waives);

                                      -4-
<PAGE>

          (b)  prove any claim in competition with the Bank in respect of any
               payment hereunder in bankruptcy or insolvency proceedings of any
               nature;

          (c)  claim any set-off or counterclaim against the JLM Domestic
               Entities in respect of any liability of the undersigned to the
               JLM Domestic Entities.

     SUBORDINATION.  The payment of any amounts due with respect to any
indebtedness of the JLM Domestic Entities now or hereafter held by the
undersigned is hereby subordinated to the prior payment in full of the
Liabilities. The undersigned will not demand, sue for, or otherwise attempt to
collect any such indebtedness. Any amounts which are collected, enforced and
received by the undersigned shall be held by the undersigned as trustee for the
Bank and shall be paid over to the Bank on account of the Liabilities without
affecting in any manner the liability of the undersigned under the other
provisions of this Guaranty.

     BANK'S BOOKS AND RECORDS.  The books and records of the Bank showing the
account among the Bank and the JLM Domestic Entities shall be admissible in any
action or proceeding and constitute prima facie evidence and proof of the items
contained therein.

     GUARANTOR'S OBLIGATIONS PRIMARY.  The obligations of the undersigned
hereunder are primary, with no recourse necessary by the Bank against the JLM
Domestic Entities or any collateral given to secure the Liabilities or against
any other person liable for or on the Liabilities prior to proceeding against
the undersigned hereunder.

     CHANGE IN LIABILITIES.  The undersigned hereby expressly assents to any
indulgence or waiver which the Bank may grant or give the JLM Domestic Entities
and/or any other person liable or obligated to the Bank for or on the
Liabilities. The undersigned authorizes the Bank to alter, amend, cancel, waive,
or modify any term or condition of the Liabilities and of the obligations of any
other person liable or obligated to the Bank for or on the Liabilities, without
notice to, or consent from, the undersigned. No compromise, settlement, or
release by the Bank of the Liabilities or of the obligations of any such other
person (whether or not jointly liable with the undersigned) and no release of
any collateral securing the Liabilities or securing the obligations of any such
other person shall affect the obligations of the undersigned hereunder. No
action by the Bank which has been assented to herein shall affect the
obligations of the undersigned to the Bank hereunder.

     FINANCIAL INFORMATION.  The undersigned will, from time to time at the
request of the Bank, provide the Bank with such information concerning the
financial condition of the undersigned as the Bank reasonably may request
(including, but not limited to, annual financial statements in a form reasonably
acceptable to the Bank and copies of the federal and state income tax returns of
the undersigned within one hundred twenty (120) days of the close of the
undersigned's fiscal year, provided that the undersigned shall have the right to
extend such one hundred twenty (120) day period to correspond with any
extensions filed with the Internal Revenue Service. The failure by the
undersigned to provide such information to the Bank within said time period
within ten (10) days of written notice of such failure by the Bank shall
constitute an event of default hereunder and all outstanding Liabilities shall
become immediately due and payable in full).

     ADDITIONAL COLLATERAL.  Upon demand by the Bank after any change in the
condition or affairs (financial or otherwise) of the JLM Domestic Entities or
the undersigned deemed by the Bank to be adverse and material, the undersigned
shall secure the payment and performance of its obligations hereunder by
delivering, assigning, or transferring to the Bank or granting the Bank a
security interest in additional collateral of a value and character reasonably
satisfactory to the Bank. The undersigned shall do all such things and execute
all such documents (including, without limitation, financing statements), as the
Bank may consider

                                      -5-
<PAGE>

necessary or desirable to give full effect to this Guaranty and to perfect and
preserve the rights and powers of the Bank hereunder.

     COSTS OF ENFORCEMENT.  The undersigned will pay on demand, without
limitation, all attorneys' fees, out-of-pocket expenses incurred by the Bank's
attorneys and all costs incurred by the Bank, including, without limitation,
costs and expenses associated with travel on behalf of the Bank, which costs and
expenses are directly or indirectly related to or in respect of the Bank's
administration, negotiation, documentation, and amendment of this guaranty and
in the Bank's efforts to collect and/or to enforce any of the obligations of the
undersigned hereunder and/or to enforce any of the Bank's rights, remedies, or
powers against or in respect of the undersigned (whether or not suit is
instituted by or against the Bank).

     BINDING EFFECT.  This instrument shall inure to the benefit of the Bank,
its successors and assigns, shall be binding upon the heirs, successors,
representatives, and assigns of the undersigned, and shall apply to all
Liabilities of the JLM Domestic Entities and any successor to the JLM Domestic
Entities, including any successor by operation of law. The undersigned hereby
acknowledges and agrees that this instrument is freely assignable by the Bank,
without the consent of the undersigned.

     BANK'S RIGHTS AND REMEDIES.  The rights, remedies, powers, privileges, and
discretions of the Bank hereunder (hereinafter, the "Bank's Rights and
Remedies") shall be cumulative and not exclusive of any rights or remedies which
it would otherwise have. No delay or omission by the Bank in exercising or
enforcing any of the Bank's Rights and Remedies shall operate as, or constitute
a waiver thereof. No waiver by the Bank of any of the Bank's Rights and Remedies
or of any default or remedies under any other agreement with the undersigned, or
of any default under any agreement with the JLM Domestic Entities, or any other
person liable or obligated for or on the Liabilities, shall operate as a waiver
of any other of the Bank's Rights and Remedies or of any default or remedy
hereunder or thereunder. No exercise of any of the Bank's Rights and Remedies
and no other agreement or transaction of whatever nature entered into between
the Bank and the undersigned, among the Bank and the JLM Domestic Entities,
and/or between the Bank and any such other person at any time shall preclude any
other exercise of the Bank's Rights and Remedies. No waiver by the Bank of any
of the Bank's Rights and Remedies on any one occasion shall be deemed a waiver
on any subsequent occasion, nor shall it be deemed a continuing waiver. All of
the Bank's Rights and Remedies, and all of the Bank's rights, remedies, powers,
privileges, and discretions under any other agreement or transaction with the
undersigned, the JLM Domestic Entities, or any such other person, shall be
cumulative and not alternative or exclusive, and may be exercised by the Bank at
such time or times and in such order of preference as the Bank in its sole
discretion may determine.

     COPIES.  This instrument and all other documents which have been or may
hereafter be furnished by the undersigned to the Bank which relate to the
Liabilities may be reproduced by the Bank by any photographic, photostatic,
microfilm or similar process. Any such reproduction shall be admissible in
evidence as the original itself in any judicial or administrative proceeding
(whether or not the original is in existence and whether or not such
reproduction was made in the regular course of business).

     CHOICE OF LAWS; CONSENT TO JURISDICTION.  This instrument shall be
governed, construed, and interpreted in accordance with the laws of the
Commonwealth of Massachusetts. The undersigned submits to the jurisdiction of
the courts of the Commonwealth of Massachusetts for all matters in connection
herewith as well as for all purposes in connection with any other relationship
between the undersigned and the Bank.

     SEVERABILITY.  Any determination that any provision herein is invalid,
illegal, or unenforceable in any respect in any instance shall not affect the
validity, legality, or enforceability of such provision in any other instance
and shall not affect the validity, legality, or enforceability of any other
provision contained herein.

     TERMINATION.  The obligations of the undersigned hereunder shall remain in
full force and effect as to all Liabilities, without regard to any reduction of
the Liabilities other than by the undersigned pursuant to this Guaranty, until

address set forth above of written notice signed by the undersigned of the
termination thereof, or (b) the delivery of written notice of termination dated
and signed by a duly authorized representative of the Bank, which notice of
termination includes specific reference to this provision. No termination hereof
shall affect any Liability in existence or outstanding ten (10) days following
the date of such actual receipt or delivery (including, without limitation,
those which are contingent or not then due and those which arise out of any
check, draft, item, or paper which was made, executed, or drawn prior to the
expiration of such ten (10) days, even if received by the Bank thereafter) nor
any obligation of the undersigned hereunder, including, without limitation, any
which by its terms includes any of the Liabilities of a contingent nature
(including, without limitation, the indemnification provided for herein). This
Guaranty shall continue to be effective or shall be automatically reinstated,
without any further action, notwithstanding any prior termination, if at any
time any payment made or value received with respect to a Liability is rescinded
or must otherwise be returned by the Bank upon the insolvency, bankruptcy or
reorganization of the JLM Domestic Entities, or otherwise, all as though such
payment had not been made or value received.

     MISCELLANEOUS.  The undersigned represents and certifies that the
undersigned read and reviewed all provisions of this Guaranty prior to its
execution and has been afforded an opportunity to consult with counsel
independently selected by the undersigned. The undersigned further represents
and certifies that the undersigned has freely and willingly executed this
Guaranty.

     WAIVER OF JURY TRIAL.  The undersigned makes the following waiver
knowingly, voluntarily, and intentionally, and understands that the Bank, in the
establishment and maintenance of the Bank's relationship with the JLM Domestic
Entities and the undersigned, is relying thereon. THE UNDERSIGNED, TO THE EXTENT
ENTITLED THERETO, HEREBY IRREVOCABLY WAIVES ANY PRESENT OR FUTURE RIGHT OF THE
UNDERSIGNED, THE JLM DOMESTIC ENTITIES OR ANY GUARANTOR OR ENDORSER OF THE JLM
DOMESTIC ENTITIES, OR ANY OTHER SIMILAR PERSON, TO A TRIAL BY JURY OF ANY CASE
OR CONTROVERSY IN WHICH THE BANK IS OR BECOMES A PARTY (WHETHER SUCH CASE OR
CONTROVERSY IS INITIATED BY OR AGAINST THE BANK OR IN WHICH THE BANK IS JOINED
AS A PARTY LITIGANT), WHICH CASE OR CONTROVERSY ARISES OUT OF, OR IS IN RESPECT
OF, ANY RELATIONSHIP AMONG THE UNDERSIGNED, THE JLM DOMESTIC ENTITIES, ANY SUCH
PERSON, AND THE BANK.

date hereof, the holders of which shall have the right, without limitation as to
amount, either to all or to a share of the balance of current dividends and
liquidating dividends after the payment of dividends and distributions on any
shares entitled to preference, and the holders of which shall ordinarily, in the
absence of contingencies or in the absence of any provision to the contrary in
the Company's [Certificate of Incorporation], be entitled to vote for the
election of a majority of directors of the Company (even though the right so to
vote has been suspended by the happening of such a contingency or provision),
and (c) any other securities into which or for which any of the securities
described in (a) or (b) may be converted or exchanged pursuant to a plan of
recapitalization, reorganization, merger, sale of assets or otherwise.

     1.3  "Exchange Act" means the Securities Exchange Act of 1934, or any
similar federal statute, and the rules and regulations of the Commission
thereunder, all as the same shall be in effect at the time.

venture, trust, or unincorporated organization, or a government or any agency or
political subdivision thereof.

Securities Act, Section 4(l) of the Securities Act or Rule 144 promulgated under
the Securities Act.

     1.6  "Warrant" means that certain Stock Purchase Warrant of even date

<PAGE>

     1.7  "Securities Act" means the Securities Act of 1933, or any similar
federal statute, and the rules and regulations of the Commission thereunder, all
as the same shall be in effect at the time.

     Section 2. "Piggy-Back" Registrations. If at any time the Company shall
determine to register under the Securities Act (including pursuant to a demand
of any stockholder of the Company exercising registration rights) any of its
Securities, other than on Form S-8 or Form S-4 or their then equivalents, it
shall send to each holder of Registrable Shares, including each holder who has
the right to acquire Registrable Shares, written notice of such determination
and, if within 20 days after receipt of such notice, such holder shall so
request in writing, the Company shall use its best efforts to include in such
registration statement all or any part of the Registrable Shares such holder
requests to be registered therein, except that if, in connection with any
offering involving an underwriting of Common Stock to be issued by the Company,
the managing underwriter shall impose a limitation on the number of shares of
such Common Stock which may be included in any such registration statement
because, in its judgment, such limitation is necessary to effect an orderly
public distribution, and such limitation is imposed pro rata with respect to all
securities whose holders have a contractual, incidental ("piggy back") right to
include such securities in the registration statement and as to which inclusion
has been requested pursuant to such right and there is first excluded from such
registration statement all shares of Common Stock sought to be included therein
by (i) any director, officer or employee of the Company or any subsidiary, (ii)
any holder thereof not having any such contractual, incidental registration
rights, and (iii) any holder thereof having contractual, incidental registration
rights subordinate and junior to the rights of the holders of Registrable
Shares, then the Company shall be obligated to include in such registration
statement only such limited portion (which may be none) of the Registrable
Shares with respect to which such holder has requested inclusion hereunder. No
incidental right under this Section 2 shall be construed to limit any
registration required under Section 3.

     Section 3. Demand Registrations. If on not more than two (2) occasions
(including an occasion of registration on Form S-1 or S-18 or their then
equivalents) one or more holders of at least 20% of the Registrable Shares shall
notify the Company in writing that it or they intend to offer or cause to be
offered for public sale at least 20% of the Registrable Shares, the Company will
so notify all holders of Registrable Shares, including all holders who have a
right to acquire Registrable Shares. Upon written request of any holder given
within 20 days after the receipt by such holder from the Company of such
notification, the Company will use its best efforts to cause such of the
Registrable Shares as may be requested by any holder thereof (including the
holder or holders giving the initial notice of intent to offer) to be registered
under the Securities Act as expeditiously as possible. The Company shall not be
required to effect more than two (2) registrations pursuant to this Section 3,
or more than one such registration during any 12 month period. If the Company
determines to include shares to be sold by it in any registration requests
pursuant to this Section 3, such registration shall be deemed to have been a
registration under Section 2 of this Agreement.
<PAGE>

     Section 4.  Short-Form Registration on Form S-3. In addition to the rights
provided the holder of Registrable Shares in Sections 2 and 3 above, if the
registration of Registrable Shares under the Securities Act can be effected on
Form S-3 (or any similar or successor form promulgated by the Commission), the
Company will so notify each holder of Registrable Shares, including each holder
who has a right to acquire Registrable Shares, and then will, as expeditiously
as possible, use its best efforts to effect qualification and registration under
the Securities Act on said Form S-3 of all or such portion of the Registrable
Shares as the holder or holders shall specify; provided, however, that the
market value of the Registrable Shares to be sold in any such registration shall
be estimated to be at least $500,000 at the time of filing such registration
statement; and provided further, that the Company shall not be required to
effect more than two (2) such registrations pursuant to this Section 4 in any
twelve-month period.

     Section 5.  Effectiveness of Registration Statements. The Company will use
its best efforts to maintain the effectiveness of any registration statement
pursuant to which any of the Registrable Shares are being offered until the
earlier to occur of (i) the completion by the underwriters of the distribution
pursuant to such registration statement or (ii) 90 days after the effectiveness
of any registration statement, and from time to time will amend or supplement
such registration statement and the prospectus contained therein as and to the
extent necessary to comply with the Securities Act and any applicable state
Securities statute or regulation. The Company will also provide each holder of
Registrable Shares with as many copies of the prospectus contained in any such
registration statement as it may reasonably request.

     Section 6.  Indemnification of Holders of Registrable Shares. In the event
that the Company registers any of the Registrable Shares under the Securities
Act, the Company will, to the extent permitted by law, indemnify and hold
harmless each holder and each underwriter of the Registrable Shares (including
their officers, directors, affiliates and partners) so registered (including any
broker or dealer through whom such shares may be sold) and each Person, if any,
who controls such holder or any such underwriter within the meaning of Section
15 of the Securities Act from and against any and all losses, claims, damages,
expenses or liabilities, joint or several, to which they or any of them become
subject under the Securities Act or under any other statute or at common law or
otherwise, and, except as hereinafter provided, will reimburse each such holder,
each such underwriter and each such controlling Person, if any, for any legal or
other expenses reasonably incurred by them or any of them in connection with
investigating or defending any actions whether or not resulting in any
liability, insofar as such losses, claims, damages, expenses, liabilities or
actions arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in the registration statement or any
filing with any state Securities commission or agency, in any preliminary or
amended preliminary prospectus or in the final prospectus (or the registration
statement or prospectus as from time to time amended or supplemented by the
Company) or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary in
order to make the statements therein not misleading, or any violation by the
Company of any rule or regulation promulgated under the Securities Act or any
state Securities laws or regulations applicable to the Company and relating to
action or inaction required of the Company in connection with such registration,
unless (i) such untrue statement or alleged untrue statement or omission or
alleged omission was made in such registration statement, preliminary or amended

                                      -3-
<PAGE>

preliminary prospectus or final prospectus in reliance upon and in conformity
with information furnished in writing to the Company in connection therewith by
such holder of Registrable Shares, any such underwriter or any such controlling
Person expressly for use therein.

     Promptly after receipt by any holder of Registrable Shares, any underwriter
or any controlling Person of notice of the commencement of any action in respect
of which indemnity may be sought against the Company, such holder of Registrable
Shares, or such underwriter or such controlling Person, as the case may be, will
notify the Company in writing of the commencement thereof, and, subject to the
provisions hereinafter stated, the Company shall assume the defense of such
action (including the employment of counsel, who shall be counsel reasonably
satisfactory to such holder of Registrable Shares, such underwriter or such
controlling Person, as the case may be), and the payment of expenses insofar as
such action shall relate to any alleged liability in respect of which indemnity
may be sought against the Company.

     Such holder of Registrable Shares, any such underwriter or any such
controlling Person shall have the right to employ separate counsel in any such
action and to participate in the defense thereof but the fees and expenses of
such counsel shall not be at the expense of the Company unless the employment of
such counsel has been specifically authorized by the Company. The Company shall
not be liable to indemnify any Person for any settlement of any such action
effected without the Company's consent (which consent shall not be unreasonably
withheld or delayed). The Company shall not, except with the approval of each
party being indemnified under this Section 6, consent to entry of any judgment
or enter into any settlement which does not include as an unconditional term
thereof the giving by the claimant or plaintiff to the parties being so
indemnified of a release from all liability in respect to such claim or
litigation.

     In order to provide for just and equitable contribution to joint liability
under the Securities Act in any case in which any holder of Registrable Shares
exercising rights under this Agreement, or any controlling person of any such
holder, makes a claim for indemnification pursuant to this Section 6 but it is
judicially determined (by the entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time to appeal or the denial of the
last right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that this Section 6 provides for indemnification in
such case, then, the Company and such holder will contribute to the aggregate
losses, claims, damages or liabilities to which they may be subject (after
contribution from others) in such proportion as is appropriate to reflect the
relative fault of the Company on the one hand and of the holder of Registrable
Shares on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities, as well as any other
relevant equitable considerations. The relative fault of the Company on the one
hand and of the holder of Registrable Shares on the other shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or omission or alleged omission to state a material fact
relates to information supplied by the Company on the one hand or by the holder
of Registrable Shares on the other, and each party's relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission; provided, however, that, in any such case, (A) no such holder will be
required to contribute any amount in excess of the net proceeds received by it
pursuant to such registration statement; and (B) no person or entity guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) will be entitled to contribution from any person or entity who
was not guilty of such fraudulent misrepresentation.

     Section 7.  Indemnification of Company. In the event that the Company
registers any of the Registrable Shares under the Securities Act, each holder of
the Registrable Shares so

                                      -4-
<PAGE>

registered, to the extent permitted by law, will indemnify and hold harmless the
Company, each of its directors, each of its officers who have signed or
otherwise participated in the preparation of the registration statement, each
underwriter of the Registrable Shares so registered (including any broker or
dealer through whom such of the shares may be sold) and each Person, if any, who
controls the Company within the meaning of Section 15 of the Securities Act from
and against any and all losses, claims, damages, expenses or liabilities, joint
or several, to which they or any of them may become subject under the Securities
Act or under any other statute or at common law or otherwise, and, except as
hereinafter provided, will reimburse the Company and each such director,
officer, underwriter or controlling Person for any legal or other expenses
reasonably incurred by them or any of them in connection with investigating or
defending any actions whether or not resulting in any liability, insofar as such
loses, claims, damages, expenses, liabilities or actions arise out of or are
based upon any untrue statement or alleged untrue statement of a material fact
contained in the registration statement or any filing with any state Securities
commission or agency, in any preliminary or amended preliminary prospectus or in
the final prospectus (or in the registration statement or prospectus as from
time to time amended or supplemented) or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary in order to make the statements therein not
misleading, but only insofar as any such statement or omission was made in
reliance upon and in conformity with information furnished in writing to the
Company in connection therewith by such holder of Registrable Shares expressly
for use therein; provided, however, that such holder's obligations hereunder
shall be limited to an amount equal to the net proceeds received by such holder
of the Registrable Shares sold in such registration.

     Promptly after receipt of notice of the commencement of any action in
respect of which indemnity may be sought against such holder of Registrable
Shares, the Company will notify such holder of Registrable Shares in writing of
the commencement thereof, and such holder of Registrable Shares shall, subject
to the provisions hereinafter stated, assume the defense of such action
(including the employment of counsel, who shall be counsel reasonably
satisfactory to the Company) and the payment of expenses insofar as such action
shall relate to the alleged liability in respect of which indemnity may be
sought against such holder of Registrable Shares.

     The Company and each such director, officer, underwriter or controlling
Person shall have the right to employ separate counsel in any such action and to
participate in the defense thereof' but the fees and expenses of such counsel
shall not be at the expense of such holder of Registrable Shares unless
employment of such counsel has been specifically authorized by such holder of
Registrable Shares. Such holder bf Registrable Shares shall not be liable to
indemnify any Person for any settlement of any such action effected without such
holder's consent (which consent shall not be unreasonably withheld or delayed).

     In order to provide for just and equitable contribution to joint liability
under the Securities Act in any case in which the Company exercising its rights
under this Agreement, makes a claim for indemnification pursuant to this Section
7, but it is judicially determined (by the entry of a final judgment or decree
by a court of competent jurisdiction and the expiration of time to appeal or the
denial of the last right of appeal) that such indemnification may not be
enforced in such case notwithstanding that this Section 7 provides for
indemnification, in such case, then, the Company and such holder will contribute
to the aggregate losses, claims, damages or liabilities to which they may be
subject (after contribution from others) in such proportion as is appropriate to
reflect the relative fault of the Company on the one hand and of the holder of
Registrable Shares on the other in connection with the statements or omissions
which resulted in such losses, claims, damages or omissions which resulted in

                                      -5-
<PAGE>

such losses, claims, damages or liabilities, as well as any other relevant
equitable considerations. The relative fault of the Company on the one hand and
of the holder of Registrable Shares on the other shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or omission or alleged omission to state a material fact
relates to information supplied by the Company on the one hand or by the holder
of Registrable Shares on the other, and each party's relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission; provided, however, that, in any such case, (A) no such holder will be
required to contribute any amount in excess of the net proceeds received by it
pursuant to such registration statement; and (B) no person or entity guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) will be entitled to contribution from any person or entity who
was not guilty of such fraudulent misrepresentation.

     Section 8.  Damages. The Company recognizes and agrees that the holder of
Registrable Shares will not have an adequate remedy if the Company fails to
comply with this Agreement and that damages may not be readily ascertainable,
and the Company expressly agrees that, in the event of such failure, it shall
not oppose an application by the holder of Registrable Shares or any other
Person entitled to the benefits of this Agreement requiring specific performance
of any and all provisions hereof or enjoining the Company from continuing to
commit any such breach of this Agreement.

     Section 9.  Further Obligations of the Company. Whenever under the
preceding Sections of this Agreement, the Company is required hereunder to
register Registrable Shares, it agrees that it shall also do the following at
its sole expense:

          (a)  Furnish to each selling holder such copies of each preliminary
     and final prospectus and such other documents as said holder may reasonably
     request to facilitate the public offering of its Registrable Shares;

          (b)  Use its best efforts to register or qualify the Registrable
     Shares covered by said registration statement under the applicable
     Securities or "blue sky" laws of such jurisdictions as any selling holder
     may reasonably request; provided; however, that the Company shall not be
     obligated to qualify to do business in any jurisdiction where it is not
     then so qualified or to take any action which would subject it to the
     service of process in suits other than those arising out of the offer or
     sale of the Securities covered by the registration statement in any
     jurisdiction where it is not then so subject;

          (c)  Use its best efforts to list, or qualify for trading, such
     Registrable Shares on any and all national securities exchanges and
     markets, inter-dealer quotation systems, over-the-counter trading systems
     and bulletin board trading systems on which any of the Company's securities
     of the same class as the Registrable Shares shall then be listed or
     qualified for trading;

          (d)  Furnish to each selling holder a "signed counterpart" of:

               (i)  an opinion of counsel for the Company, dated the effective
          date of the registration statement, and

                                      -6-
<PAGE>

               (ii) "comfort" letters signed by the Company's independent public
          accountants who have examined and reported on the Company's financial
          statements included in the registration statement, to the extent
          permitted by the standards of the American Institute of Certified
          Public Accountants,

covering substantially the same matters with respect to the registration
statement (and the prospectus included therein) and (in the case of the
accountants' "comfort" letters) with respect to events subsequent to the date of
the financial statements, as are customarily covered in opinions of issuer's
counsel and in accountants' "comfort" letters delivered to the underwriters in
underwritten public offerings of Securities, to the extent that the Company is
required to deliver or cause the delivery of such opinion or "comfort" letters
to the underwriters in an underwritten public offering of Securities;

          (e)  Permit each selling holder or its counsel or other
     representatives to inspect and copy such corporate documents and records as
     may reasonably be requested by them;

          (f)  Furnish to each selling holder a copy of all documents filed and
     all correspondence from or to the Commission in connection with any such
     offering of Securities;

          (g)  Use its best efforts to insure the obtaining of all necessary
     approvals from the National Association of Securities Dealers, Inc.; and

          (h)  Otherwise use its best efforts to comply with all applicable
     rules and regulations of the Commission.

     Section 10.  Expenses. In the case of any registration under Section 2, 3
or 4 of this Agreement, the Company shall bear all costs and expenses of each
such registration, including, but not limited to, printing, legal and accounting
expenses, Securities and Exchange Commission and National Association of
Securities Dealers, Inc. filing fees and expenses, and "blue sky" fees and
expenses and the reasonable fees and disbursements of not more than one counsel
for the selling holders of Registrable Shares in connection with the
registration of their Registrable Shares; provided, however, that the Company
shall have no obligation to pay or otherwise bear any portion of the
underwriters, commissions or discounts attributable to the Registrable Shares.

     The Company shall pay all expenses in connection with any registration
initiated under this Agreement which is withdrawn, delayed or abandoned at the
request of the Company, unless such registration is withdrawn, delayed or
abandoned solely because of any actions of the holders of Registrable Shares.

     Section 11.  Delay of Registration. For a period not to exceed 90 days, the
Company shall not be obligated to prepare and file, or prevented from delaying
or abandoning, a registration statement pursuant to this Agreement at any time
when the Company, in its good faith judgment with advice of counsel, reasonably
believes

          (a)  that the filing thereof at the time requested, or the offering of
     Registrable Shares pursuant thereto, would materially and adversely affect
     (a) a pending or scheduled

                                      -7-
<PAGE>

     public offering of the Company's Securities, (b) an acquisition, merger,
     recapitalization, consolidation, reorganization or similar transaction by
     or of the Company, (c) preexisting and continuing negotiations, discussions
     or pending proposals with respect to any of the foregoing transactions, or
     (d) the financial condition of the Company in view of the disclosure of any
     pending or threatened litigation, claim, assessment or governmental
     investigation which may be required thereby; and

          (b)  that the failure to disclose any material information with
     respect to the foregoing would cause a violation of the Securities Act or
     the Exchange Act.

     Section 12.  Conditions to Registration Obligations. The Company shall not
be obligated to effect the registration of Registrable Shares pursuant to
Sections 2, 3 and 4 unless all holders of Registrable Shares being registered
consent to reasonable conditions imposed by the Company as the Company shall
determine with the advice of counsel to be required by law including, without
limitation:

          (a)  conditions prohibiting the sale of shares by such holders until
     the registration shall have been effective for a specified period of time;

     furnish to the Company information about sales made in such public
     offering;

          (c)  conditions prohibiting such holders upon receipt of telegraphic
     or written notice from the Company (until further notice) from effecting

     the Company is obligated to keep the registration statement effective under

     upon receipt of notice form the Company of its intention to remove from
     registration the shares covered by such registration statement that remain
     unsold, and requiring such holders to notify the Company of the number of
     shares registered that remain unsold immediately upon receipt of notice
     from the Company; and

          (e)  conditions requiring the holders of Registrable Shares to enter

     satisfactory to the Company.

                            of JLM Industries, Inc.

Stock Purchase Warrant No. W-1

     THIS WARRANT AND ANY SHARES ACQUIRED UPON THE EXERCISE OF THIS WARRANT HAVE
NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE
SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION
THEREFROM UNDER SUCH ACT AND ANY APPLICABLE STATE SECURITIES LAWS. FURTHERMORE,
THIS WARRANT AND ANY SHARES ACQUIRED UPON THE EXERCISE OF THIS WARRANT MAY BE

                            Stock Purchase Warrant

             Void after 5:00 p.m., Eastern Time on April __, 2011


     JLM Industries, Inc., a [Delaware] corporation (together with any
corporation which shall succeed to or assume the obligations of JLM Industries,
Inc. hereunder, the "Company"), hereby certifies that, for value received,
Citizens Bank of Massachusetts, or its assigns ("Citizens"), is entitled,
subject to the terms set forth below, to purchase from the Company at any time
and from time to time until the expiration hereof pursuant to Section 2.3 below,
up to Five Hundred Thousand (500,000) fully paid and non-assessable shares of
the Company's common stock, $___ par value per share the "Warrant Stock"), at a
purchase price per share of $_____ (the "Exercise Price"). The number of shares
of Warrant Stock and the Exercise Price are subject to adjustment from time to
time as provided herein. This Warrant is issued in connection with that certain
First Amendment to Amended and Restated Credit Agreement (the "Loan Agreement")
of even date herewith between the Company and Citizens, a copy of which is on
file at the principal office of the Company.

1.   DEFINITIONS. In addition to the terms which are defined in the body of this
Warrant, certain terms used in this Warrant are defined in Section 15 hereof.

2.   EXERCISE OF WARRANT.

     2.1. Exercise. This Warrant may be exercised prior to its expiration
pursuant to Section 2.3 hereof by the holder hereof at any time and from time to
time by surrender of this Warrant, with the form of Notice of Exercise or
Conversion at the end hereof duly executed by
<PAGE>

such holder, to the Company at its principal office, accompanied by payment, by
certified or official bank check payable to the order of the Company or by wire
transfer to its account, in the amount obtained by multiplying the number of
shares of Warrant Stock for which this Warrant is then being exercised by the
Exercise Price then in effect. In the event the Warrant is not exercised in
full, the Company, at its expense, will forthwith issue and deliver to or upon
the order of the holder hereof a new Warrant or Warrants of like tenor, in the
name of the holder hereof or as such holder (upon payment by such holder of any
applicable transfer taxes) may request, calling in the aggregate on the face or
faces thereof for the number of shares of Warrant Stock equal to the balance of
the number shares then purchasable under this Warrant. Upon any exercise of this
Warrant, in whole or in part, the holder hereof may, in lieu of paying the
aggregate Exercise Price which otherwise would be payable with respect to the
shares of Warrant Stock for which this Warrant is then being exercised
(collectively, the "Exercise Shares"), (a) in the event the holder of this
Warrant is also the holder of a promissory note of the Company, convert a like
amount of outstanding principal and/or interest amount of such note into such
number of shares of Warrant Stock, or (b) surrender this Warrant to the Company
together with a notice of cashless exercise, in which event the Company shall
issue to the Holder the number of shares of Warrant Stock determined as follows:

                    X = Y (A-B)/A
     where:
                    X = the number of shares of Warrant Stock to be issued to
                    the Holder.

                    Y = the number of shares of Warrant Stock with respect to
                    which this Warrant is being exercised.

                    A = the Fair Market Value (as defined below) of one share of
                    Warrant Stock.

                    B = the Exercise Price.

     For purposes of this Section 2.1, the "Fair Market Value" of one share of
Warrant Stock (the "Fair Market Value") at any date shall be determined as
follows:

          (a)  If shares of the same class or series as the Warrant Stock are at
     such time listed or admitted for trading on any national securities
     exchange or quoted on the National Quotation Market System of the National
     Association of Securities Dealers, Inc. Automated Quotation System
     ("NASDAQ"), then the Fair Market Value shall be equal to the closing market
     price of such shares on the trading day immediately preceding the date of
     holder's Notice of Exercise or Conversion. As used in this subparagraph
     (a), "market price" for such trading day shall be the average of the
     closing prices on such day of such shares on all domestic primary national
     securities exchanges on which such shares are then listed, or, if there
     shall have been no sales on any such exchange on such day, the average of
     the highest bid and lowest asked prices on all such exchanges at the

                                      -2-
<PAGE>

     end of such day, or if such shares shall not be so listed, the average of
     the representative bid and asked prices at the end of such trading day as
     reported by NASDAQ.

          (b)  If shares of the same class or series as the Warrant Stock are
     not at such time listed or admitted for trading on any national securities
     exchange or quoted on NASDAQ, then the Fair Market Value of one share of
     Warrant Stock shall be determined by the Board of Directors of the Company
     in its reasonable good faith judgment; provided, that if Citizens advises
     the Company in writing that Citizens disagrees with such determination,
     then Citizens and the Company shall promptly select a reputable investment
     banking or appraisal firm to undertake a valuation of such shares. If the
     valuation of such investment banking or appraisal firm is greater than that
     determined by the Board of Directors by five percent (5%) or more, then all
     fees and expenses of such investment banking or appraisal firm shall be
     paid by the Company. In all other circumstances, such fees and expenses
     shall be paid by Citizens. The determination of such investment banking or
     appraisal firm shall be conclusive for purposes hereof.

     2.2.  Warrant Agent In the event that a bank or trust company shall have
been appointed as trustee for the holder of the Warrant pursuant to Section 6.2
hereof, such bank or trust company shall have all the powers and duties of a
warrant agent appointed pursuant to Section 16 hereof and shall accept, in its
own name for the account of the Company or such successor entity as may be
entitled thereto, all amounts otherwise payable to the Company or such
successor, as the case may be, on exercise of this Warrant pursuant to this
Section 2.

     2.3.  Termination. This Warrant shall terminate upon the earliest to occur
of (a) exercise in full, or (b) April ___, 2011.

3.   REGISTRATION RIGHTS.

     3.1.  Registration Rights. The Warrant Stock shall have certain
registration rights as set forth in that certain Registration Rights Agreement
between the Company and Citizens of even date herewith. The Company represents
and warrants to Citizens that the Company's execution, delivery and performance
of the Registration Rights Agreement (a) has been duly authorized by all
necessary corporate action of the Company's Board of Directors and shareholders,
(b) will not violate the Certificate or By-laws, each as amended, (c) will not
violate or cause a breach or default (or an event which with the passage of time

immediately prior to such transaction beneficially own less than 50.1% of the
voting equity securities of the successor or surviving entity immediately after
such transaction (each event in clauses (a) and (b) of this Section 6.1 being an
"Acquisition") then, in each such case, the holder of this Warrant, on the
exercise hereof as provided in Section 2 hereof at any time after the
consummation of such reorganization, recapitalization, consolidation, merger,
transfer or other transaction or the effective date of such liquidation,
dissolution or winding up, as the case may be, shall receive, in lieu of the
shares of Warrant Stock (or Other Securities) issuable on such exercise
immediately prior to such consummation or effective date, the stock and other
securities and property (including cash) to which such holder would have been
entitled upon such consummation (or thereafter as a result of such consummation,
including in connection with any dissolution of the Company) if such holder had
so exercised this Warrant immediately prior thereto, all subject to further
adjustment thereafter as provided in Sections 5 and 7 hereof.

     6.2.  Appointment of Trustee for Warrant Holders Upon Dissolution. In the
event of any dissolution of the Company following the transfer of all or

Warrant.

     6.3.  Continuation of Terms. Upon an Acquisition, this Warrant shall be
assumed by the acquiring Person and shall continue in full force and effect and
the terms hereof shall be applicable to the shares of stock and other securities
and property receivable on the exercise of this Warrant after the consummation
of such reorganization, reclassification, recapitalization, consolidation,
merger, transfer or other transaction (and the effective date of dissolution
following any such transfer), as the case may be, and shall be binding upon the
issuer of any such stock or other securities, including, in the case of any such
transfer, the person acquiring all or substantially all of the properties or
assets of the Company and including, in the case of a transaction described in
Section 6.1(b) above, the person acquiring such shares of the Company's issued
and outstanding voting equity securities, whether or not such person shall have
expressly assumed the terms of this Warrant as provided in Section 8 hereof.
Notwithstanding the foregoing, at the election of Citizens, the Company shall
purchase the unexercised portion of this Warrant for cash upon the closing of
any Acquisition for an amount equal to (a) the fair market value of any
consideration that would have been received by Citizens in consideration of the
shares of Warrant Stock had Citizens exercised the unexercised portion of this
Warrant immediately before the record date for determining the shareholders

<PAGE>

     7.1.  General. If at any time there shall occur any stock split, stock
dividend, reverse stock split or other subdivision or combination of the
outstanding shares of the Warrant Stock(a "Stock Event"), then (a) the number of
shares of Warrant Stock to be received by the holder of this Warrant upon
exercise hereof shall be appropriately adjusted such that the proportion of the
number of shares issuable hereunder to the total number of shares of the Company
outstanding (on a fully diluted as converted, as exercised basis) prior to such
Stock Event is equal to the proportion of the number of shares issuable
hereunder after such Stock Event to the total number of shares of the Company
outstanding (on a fully diluted basis) after such Stock Event, and (b) the
Exercise Price shall be proportionately decreased or increased as appropriate
upon the occurrence of any stock split or other subdivision or combination of
the Warrant Stock.

8.   NO DILUTION OR IMPAIRMENT. The Company will not, by amendment of the
Certificate or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms of the
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 the Warrant against
dilution or other impairment. Without limiting the generality of the foregoing,
the Company (i) will not increase the par value of any shares of stock
receivable on the exercise of the Warrant above the amount payable therefor on
such exercise, (ii) will take all such action as may be necessary or appropriate
in order that the Company may validly and legally issue fully paid and non-
assessable shares of stock on the exercise of the Warrant from time to time
outstanding, (iii) will not transfer all or substantially all of its properties
and assets to any other person (corporate or otherwise), or consolidate with or
merge into any other person or permit any other person to consolidate with or
merge into the Company (if the Company is not the surviving entity), unless such
other person shall expressly assume in writing and will be bound by all the
terms of this Warrant.

9.   CERTIFICATE AS TO ADJUSTMENTS. In each case of any event that may require
any adjustment or readjustment in the Exercise Price, or the number or class of
shares of Warrant Stock issuable on the exercise of this Warrant the Company at
its expense will promptly prepare a certificate setting forth such adjustment or
readjustment, and showing, in detail, the facts upon which any such adjustment
or readjustment is based, including a statement of (i) the consideration
received or receivable by the Company for any additional shares of Warrant Stock
(or Other Securities) issued or sold or deemed issued or sold,(ii) the number of
shares of Warrant Stock then outstanding or deemed to be outstanding on a fully
diluted, as converted, as exercised basis, and (iii) the Exercise Price and the
number of shares of Warrant Stock to be received upon exercise of this Warrant,
in effect immediately prior to such adjustment or readjustment and as adjusted
and readjusted (if required by Section 7) on account thereof. The Company will
forthwith mail a copy of each such certificate to each holder of a Warrant, and
will, on the written request at any time of any holder of a Warrant, furnish to
such holder a like certificate setting forth the calculations used to determine
such adjustment or readjustment. At its option, the holders of a Warrant may
confirm the adjustment noted on the certificate by causing such

                                      -6-
<PAGE>

adjustment to be computed by the Company's independent accounting firm or
another independent certified public accountant at the expense of the Company.
