        This Strategic Alliance Agreement (this "Agreement"), dated and
effective as of February 7, 2000 (the "Effective Date"), is by and between
Optimum Logistics Ltd. ("Optimum") and CheMatch.com, Inc. ("CheMatch") (Optimum

during the Term (as defined in Section 2 below) of this Agreement. Such meetings
shall be held on a date and at a time and location to be agreed upon by the
Parties not less than ten (10) business days before each meeting. At each such

<PAGE>   3

meeting, the Party responsible for preparing the minutes of such meeting shall
circulate a draft of such minutes to the other Party for review and comment. The
Parties shall then work together in good faith to revise such minutes to their
mutual satisfaction. Upon completion of such revisions, each Party shall execute
two (2) copies of such minutes, retain one of such executed copies for its
records and deliver the other to the other Party. No agreement reached or action
taken or directed to be taken at any such meeting shall be binding on the
Parties unless the minutes of such meeting have been executed by both Parties.

        2.     TERM

        (a) Initial Term. Unless earlier terminated in accordance with the
provisions of Section 12 hereof, the initial term of this Agreement (the
"Initial Term") is three (3) years, commencing on the Effective Date and
extending through the third (3rd) anniversary of that date, after which this
Agreement shall terminate unless extended pursuant to Section 2(b) below (the
Initial Term together with all such extensions, the "Term").

        (b)    Extension of Initial Term.

               (i) On or before the first anniversary of the Effective Date, the
        Parties shall attempt in good faith to develop a mutually agreeable set
        of performance criteria to be achieved by the Parties under this
        Agreement by specified dates, which performance criteria and dates shall
        be attached hereto as Exhibit A. Exhibit A shall set forth the
        performance criteria that must be met in order to extend the Initial
        Term for one (1) year following the three-year period specified in
        Section 2(a) above. In the event that such performance criteria are met
        by both Parties on or before the dates set forth therein, the Initial
        Term shall be automatically extended for an additional one (1) year
        period. Thereafter, the Term shall be automatically extended for
        successive one (1) year periods unless either Party provides the other
        written notice of its desire not to extend the Term at least one hundred
        twenty (120) days prior to the then-scheduled termination thereof.

               (ii) In the event that one or more of the performance criteria
        set forth on Exhibit A have not been achieved on or before the
        applicable date or dates set forth therein by either Party but the
        Parties nevertheless desire to extend the Initial Term, the Parties may
        do so by executing a written amendment to this Agreement extending the
        Initial Term not less than ninety (90) days prior to then-scheduled
        termination thereof.

               (iii) In the event that the Parties are unable to agree on the
        set of performance criteria and dates to be attached hereto as Exhibit A
        on or before the first anniversary of the Effective Date, the Initial
        Term and this Agreement shall terminate on the date that is six (6)
        months after the first anniversary of the Effective Date, unless
        otherwise agreed in writing by the Parties at least ninety (90) days
        prior to such date.

        3.     EQUITY INVESTMENT

        (a) CheMatch Investment in Optimum. If, during the Initial Term of this
Agreement, Optimum conducts a private offering of any of its securities, whether
debt or equity, for an



                                       3
<PAGE>   4

aggregate amount of at least five million dollars ($5,000,000), and such
offering is extended to investors other than, or in addition to, financial
institutions, venture capital funds, private equity funds, affiliates of Optimum
and employees of Optimum (such investors hereinafter, "Strategic Investors"),
Optimum shall offer CheMatch the opportunity to invest at least one million
dollars ($1,000,000) in the first such offering (but not in any subsequent
offering) made by Optimum during the Initial Term on the same financial terms
offered to other Strategic Investors in such offering; provided, however, that
CheMatch's participation in such offering shall be limited to a maximum of ten
percent (10%) of such offering, unless Optimum otherwise agrees in writing.

        (b) Investment in Competitors. During the Initial Term, neither Party
shall make any investment of any kind, whether debt, equity or convertible to
equity, in any direct competitor of the other Party.

        (c) Competing Systems. During the Term, neither Party, nor any of their
respective affiliates, shall build, establish, offer or maintain a system that
would constitute a "direct competitor" of the other Party.

        (d) "Direct Competitors". For purposes of this Agreement, "direct
competitor" of CheMatch shall include all internet based trading platforms for
electronic trading of bulk petrochemicals and polymers among third parties, and
"direct competitor" of Optimum shall include all integrated logistics operations
and tracking systems for bulk liquid shipments.

        4.     REVENUE SHARING

        (a) TransLink Participants. During the Term of this Agreement, each time
an entity represented by a registered user of the TransLink System (each such
entity and all of its affiliates collectively, a "TransLink Participant")
obtains a spot contract with a firm price for transportation via one or more
modes (including tanker, barge or tank container) as to a product, subject to
customary terms and conditions ( a "Freight Fixture"), through use of the
TransLink System and such TransLink Participant subsequently utilizes a
hyperlink connection or other electronic means of direct data or information
exchange established between the TransLink System and the CheMatch System
pursuant to this Agreement to access the CheMatch System and execute a trade as
to such product using the CheMatch System that is to be completed using the
transportation secured by such Freight Fixture, CheMatch shall pay Optimum
twenty percent (20%) of the total commission revenue earned by CheMatch from
such TransLink Participant in respect of such product trade, regardless of
whether such TransLink Participant is a buyer or a seller in such product trade;
provided, however, that the maximum amount payable by CheMatch to Optimum under
this Section 4(a) during any one contract year during the Term of this Agreement
shall be five million dollars ($5,000,000). Once the maximum yearly payment of
five million dollars ($5,000,000) by CheMatch to Optimum has been reached for a
particular contract year, CheMatch shall have no further payment obligations to
Optimum under this Section 4(a) during such contract year; provided, however,
that all other terms and conditions of this Agreement shall remain in full force
and effect. All amounts payable under this Section 4(a) shall be due and payable
monthly in arrears. Payments due under this Section 4(a) for each month during
which this Agreement remains in effect shall be due and payable on or before the
twentieth (20th) day of the next succeeding month.




                                       4
<PAGE>   5

        (b) CheMatch Participants. During the Term of this Agreement, each time
an entity represented by a registered user of the CheMatch System (each such
entity and all of its affiliates collectively, a "CheMatch Participant")
executes a trade as to a product, whether as buyer or seller, through use of the
CheMatch System and such CheMatch Participant subsequently utilizes a hyperlink
connection or other electronic means of direct data or information exchange
established between the CheMatch System and the TransLink System pursuant to
this Agreement to access the TransLink System and obtain a Freight Fixture for
the fulfillment of such product trade using the TransLink System, Optimum shall
pay CheMatch twenty percent (20%) of the total commission or other transaction
fee revenues, if any, earned by Optimum in respect of a Freight Fixture related
directly to the fulfillment of such product trade and obtained through use of
the TransLink System; provided, however, that the maximum amount payable by
Optimum to CheMatch under this Section 4(b) during any one contract year during
the Term of this Agreement shall be five million dollars ($5,000,000). Once the
maximum yearly payment of five million dollars ($5,000,000) by Optimum to
CheMatch has been reached for a particular contract year, Optimum shall have no
further payment obligations to CheMatch under this Section 4(b) during such
contract year; provided, however, that all other terms and conditions of this
Agreement shall remain in full force and effect. All amounts payable under this
Section 4(b) shall be due and payable monthly in arrears. Payments due under
this Section 4(b) for each month during which this Agreement remains in effect
shall be due and payable on or before the twentieth (20th) day of the next
succeeding month.

        (c) Verification. For purposes of verifying the amounts payable by the
Parties to each other under this Section 4, each Party shall have the right to
retain an outside firm to audit and evaluate the payments and payment
obligations of the other Party for any contract year or part thereof during
which this Agreement is in effect, and if, in a Party's sole discretion and at
its own cost, it elects to do so, such Party shall notify the other Party
thereof in writing within one hundred twenty (120) days of the end of such
contract year. The other Party shall allow such firm to have reasonable access
to its books and records and shall cause its independent accountants to make
their work papers relating to such payments and payment obligations reasonably
available to such firm; provided, however, that such outside firm shall first
execute a confidentiality agreement in a form reasonably satisfactory to such
other Party pursuant to which such outside firm agrees to limit its use of the
information contained in the books and records of such other Party and the work
papers of such other Party's independent accountants to the conduct of such
audit and evaluation and to refrain from disclosing any such information to any
third party except as may be required by law. If a Party fails to deliver such
notice within such period, the payments made by the other Party during such
contract year shall be deemed to have been finally accepted by such Party as
payment in full of all payment obligations of the other Party under Section 4(a)
or (b), as applicable, for such contract year.

        (d) Disputes. If, as a result of the analysis of an outside firm, a
Party (the "Challenging Party") wishes to challenge the payments or payment
obligations of the other Party (the "Non-Challenging Party") required by Section
4(a) or (b), as applicable, or any of the information upon which they are based,
then the Challenging Party shall make its challenge by providing the
Non-Challenging Party written notice (the "Challenge Notice"), which Challenge
Notice shall set forth in reasonable detail the basis for the challenge. Both
Parties shall use their



                                       5
<PAGE>   6

reasonable best efforts to resolve matters raised in the Challenge Notice, but
if the Parties cannot resolve their dispute within ten (10) days after receipt
of the Challenge Notice by the Non-Challenging Party, the challenge described in
such Challenge Notice shall be preserved for subsequent resolution, as described
below, by the Parties or by one of the eight largest accounting firms in the
United States that has not issued an audit report with respect to the financial
statements for either Party during the then-preceding two (2) years and is not
then under current engagement to perform audit work by either Party (the
"Independent Accountants"). The Challenging Party shall, at any time after the
expiration of such ten-day period, provide the Non-Challenging Party with the
opportunity to choose one (1) out of not less than two (2) accounting firms
designated by the Challenging Party that could qualify as Independent
Accountants. The Non-Challenging Party will have five (5) days to select one of
the firms so designated, and such firm shall be the Independent Accountants.
Failing such selection, the Challenging Party will designate one of the firms it
proposed to be the Independent Accountants. Both Parties shall execute such
reasonable and customary engagement letters as the Independent Accountants may
request. In any event, the Parties may mutually agree to select any accounting
firm to be the Independent Accountants.

        Within ten (10) days after the appointment of the Independent
Accountants, each Party shall submit to the other and to the Independent
Accountants in writing its position with respect to the challenge set forth in
the Challenge Notice and its proposed resolution of the dispute, together with
such supporting documentation as they deem necessary. Within thirty (30) days
after receiving such position statements, the Independent Accountants shall
select one of the two proposed resolutions to the dispute (but not itself
propose another resolution) that it determines, in its sole discretion, to be
the most reasonable proposal in light of the provisions of this Agreement. Such
selection shall be final and binding on both Parties. The fees and expenses of
the Independent Accountants shall be borne by the Party whose proposal is not
selected. Both Parties jointly and severally exculpate and release the
Independent Accountants from any liability with respect to any decision or
judgment that the Independent Accountants may take or commit during the course
of their activities described above.

        (e) "Contract Year". For purposes of this Agreement, "contract year"
shall mean a period beginning on the Effective Date or any anniversary thereof
and extending through the day immediately preceding the next succeeding
anniversary of the Effective Date.

        5.     JOINT MARKETING

        (a) Cross-Promotion. The Parties hereby agree to cooperate in good faith
to promote the Alliance and the use of their respective services offered through
the TransLink System and the CheMatch System by third parties. To that end,
Optimum will prominently display on the TransLink System website (the "TransLink
Site") hyperlinks to the CheMatch System website, which is currently located at
WWW.CHEMATCH.COM (the "CheMatch Site"), which hyperlinks shall conform to the
requirements set forth in the Standards (as defined in Subsection 6(a)(i)).
Likewise, CheMatch will prominently display on the CheMatch Site hyperlinks to
the TransLink Site, which hyperlinks shall conform to the requirements set forth
in the Standards. Additionally, Optimum shall exclusively promote CheMatch as
the preferred Independent Trading Platform (as defined below) for electronic
trading of bulk petrochemicals


                                       6
<PAGE>   7

among third parties in substantially all of Optimum's promotional materials,
sales calls and other promotions in connection with the TransLink System which
refer to such trading platforms, and CheMatch shall exclusively promote Optimum
as the preferred provider of integrated logistics services for bulk liquid
petrochemical shipments in substantially all of CheMatch's promotional
materials, sales calls and other promotions in connection with the CheMatch
System which refer to such integrated logistics services. Each Party shall
obtain the written approval of the other Party prior to releasing any sales or
promotional materials or other publicity concerning the alliance, the terms of
this Agreement or the other Party's service offerings, which approval shall not
be unreasonably withheld. For the purposes of this Agreement, Independent
Trading Platform shall mean a trading platform which is not (i) jointly or
solely operated by any of the top ten (10) petrochemical companies; (ii) offered
under the brand name of any of the top ten (10) petrochemical companies; or
(iii) jointly or solely operated by any of the top ten (10) consumers or
producers of petrochemicals. The determination of a company's rank shall be made
on the basis of the consolidated international revenue of the company for the
last fiscal year.

        (b) Optimum Strategic Prospects. The Parties agree that Exhibit B
contains a list of entities with whom CheMatch currently has an ongoing
commercial relationship and with whom Optimum would like to develop a regular
commercial relationship (each an "Optimum Strategic Prospect"). CheMatch agrees
to make good faith efforts to assist Optimum in establishing such a commercial
relationship with the Optimum Strategic Prospects. For each Optimum Strategic
Prospect which CheMatch successfully refers to Optimum prior to the expiration
of Exhibit B as provided below, such referral to be conclusively presumed by the
execution of a signed services contract with respect to the use of the TransLink
System between Optimum and such Optimum Strategic Prospect, Optimum shall pay
CheMatch twenty percent (20%) of the gross revenue earned and actually received
from such Optimum Strategic Prospect under such contract for one (1) year
following the execution of such contract. Notwithstanding any other provision of
this Agreement, Exhibit B shall expire and be of no further force or effect on
the first anniversary of the Effective Date unless otherwise agreed in writing
prior to such expiration date; provided, however, that, upon expiration of
Exhibit B, Optimum's payment obligations under this Section 5(b) in respect of
any Optimum Strategic Prospects successfully referred to Optimum by CheMatch (as
evidenced by the execution of a signed services contract with respect to the use
of the TransLink System between Optimum and such Optimum Strategic Prospect)
prior to such expiration date shall survive such expiration of Exhibit B; and
provided, further, that all other provisions of this Agreement shall remain in
full force and effect following such expiration of Exhibit B.

        (c) CheMatch Strategic Prospects. The Parties agree that Exhibit C
contains a list of entities with whom Optimum currently has an ongoing
commercial relationship and with whom CheMatch would like to develop a regular
commercial relationship (each a "CheMatch Strategic Prospect"). Optimum agrees
to make good faith efforts to assist CheMatch in establishing such a commercial
relationship with the CheMatch Strategic Prospects. For each CheMatch Strategic
Prospect which Optimum successfully refers to CheMatch prior to the expiration
of Exhibit C as provided below, such referral to be conclusively presumed by the
execution of a signed services contract with respect to the use of the CheMatch
System between CheMatch and such CheMatch Strategic Prospect, CheMatch shall pay
Optimum twenty percent (20%) of the gross revenue


                                       7
<PAGE>   8

earned and actually received from such CheMatch Strategic Prospect under such
contract for one (1) year following the execution of such contract.
Notwithstanding any other provision of this Agreement, Exhibit C shall expire
and be of no further force or effect on the first anniversary of the Effective
Date unless otherwise agreed in writing prior to such expiration date; provided,
however, that, upon expiration of Exhibit C, CheMatch's payment obligations
under this Section 5(c) in respect of any CheMatch Strategic Prospects
successfully referred to CheMatch by Optimum (as evidenced by the execution of a
signed services contract with respect to the use of the CheMatch System between
CheMatch and such CheMatch Strategic Prospect) prior to such expiration date
shall survive such expiration of Exhibit C; and provided, further, that all
other provisions of this Agreement shall remain in full force and effect
following such expiration of Exhibit C.

ITS SERVICES, OR ITS RESPECTIVE WEBSITE, INCLUDING ANY AND ALL IMPLIED
WARRANTIES OR CONDITIONS OF QUALITY, SUITABILITY, TITLE, NONINFRINGEMENT,

                                       12
<PAGE>   13

OR NOT THE WARRANTING PARTY KNOWS, HAS REASON TO KNOW, HAS BEEN ADVISED, OR IS
OTHERWISE IN FACT AWARE OF ANY SUCH PURPOSE), WHETHER ALLEGED TO ARISE BY LAW,
BY REASON OF CUSTOM OR USAGE IN THE TRADE, OR BY COURSE OF DEALING.

        9.     CONFIDENTIALITY

        (a) Obligations of Parties. Each Party understands and acknowledges that
so long as this Agreement remains in effect, the Parties will have access to
certain Confidential Information (as defined in Section 9(b) below) concerning
their respective businesses that is a valuable and unique asset of the
respective Parties upon which their respective businesses are dependent. To
insure the continued secrecy of this Confidential Information, and in
consideration of the services provided to each other hereunder, each Party
agrees not to disclose such information of the other Party or permit such
information of the other Party to be disclosed to any third party while this
Agreement remains in effect or at any time thereafter, without the prior written
consent of the other Party. Each Party further understands and acknowledges that
if this Agreement is terminated for any reason, neither Party shall take or
retain, without prior written authorization from the other Party, originals or
copies of any records, papers, programs, computer software, documents, fee
books, files, or any other matter of whatever nature which is, contains or may
facilitate access to Confidential Information. The Parties agree that there
shall be a rebuttable presumption that a Party's disclosure to a third party of
Confidential Information of the other Party will not result in irreparable
damage or harm to such other Party and that monetary damages will be adequate to
compensate such other Party for any damage or harm resulting from such
disclosure. Any Party who seeks injunctive or other equitable relief against the
other Party in respect of any disclosure of the Party's Confidential Information
to a third party by such other Party shall be required to prove, by clear and
convincing evidence, that such disclosure will result in irreparable damage or
harm to the Party and that monetary damages will not be adequate to compensate
the Party for any damage or harm resulting from such disclosure. Subject to
Section 9(c) below, a Party may only disclose Confidential Information when
disclosure by such Party is required under applicable law or by a valid subpoena
or other court or governmental order, decree, regulation or rule; provided,
however, that if disclosure is required under this provision, such Party shall
advise the other Party of the requirement to disclose Confidential Information
prior to such disclosure and as soon as reasonably practicable after such Party
becomes aware of such required disclosure or aware that an action has been taken
seeking such disclosure unless such notice is legally prohibited; and provided
further, that upon the request of the other Party, such Party agrees to
reasonably cooperate with and at the expense of the other Party in any
reasonable and lawful actions which the other Party takes to resist such
disclosure, limit the information to be disclosed or limit the extent to which
the information so disclosed may be used or made available to third parties.

        (b) "Confidential Information". For purposes of this Agreement and
except as provided in Section 9(c) below, "Confidential Information" shall
include, without limitation, any and all secrets or confidential technology,
intellectual property rights, proprietary information, customer or supplier
lists, trade secrets, records, notes, memoranda, Data (as defined in Section
7(a) above), ideas, processes, methods, techniques, systems, formulas, patent
applications, models, devices, programs, computer software, writings, research,
personnel information,


                                       13
<PAGE>   14

customer or supplier information, plans or any other information of whatever
nature in the possession or control of a Party that is not generally known or
available to members of the general public, including any copies, worksheets, or
extracts from any of the above.

        (c) Exceptions. The term "Confidential Information" of a Party shall not
include any information which (i) is or becomes generally available to and known
by the public (other than as a result of an impermissible disclosure directly or
indirectly by the other Party), (ii) is or becomes available to the other Party
on a non-confidential basis from a source other than the Party, provided, that
such source is not and was not bound by a confidentiality agreement with, or
other obligation of secrecy to, the Party, or (iii) has been or is hereafter
independently acquired by the other Party without violating any confidentiality
agreement with, or other obligation to, the Party.

               relates to content, products or functions provided by CheMatch
               and not to any Third Party Claims directly relating to jointly
               approved content, designs or specifications or to content,

                      (B) any material breach of any representation, warranty or

which an Indemnified Person intends to make a claim for indemnification against
Optimum under Section 10(a), or against CheMatch under Section 10(b) (as the
case may be, the "Indemnifying Party"), the Indemnified Person shall promptly
(but in no event more than ten (10) days after learning of such claim) give
written notice to the Indemnifying Party of such Third-Party Claim and the
provisions of Sections 10(e) and (f) shall apply; provided, however, that any
failure to provide the foregoing notice on a timely basis shall not relieve the
Indemnifying Party of its obligations hereunder except to the extent that it is
prejudiced or otherwise damaged thereby.

        (e)    Control of Proceedings.

               (i) the Indemnifying Party shall have twenty (20) business days
        after receipt of the notice referred to in Section 10(d) to notify the
        Indemnified Person that it elects to conduct and control the defense of
        such claim, proceeding or suit. If the Indemnifying Party does not give
        the foregoing notice, the Indemnified Person shall have the right to
        defend, contest, settle or compromise such claim, proceeding or suit in
        the exercise of its exclusive discretion, subject to the provisions of
        Section 10(f), and the Indemnifying Party shall, upon request from any
        Indemnified Person, promptly pay to such Indemnified Person in
        accordance with the other terms of this Section 10 the amount of any
        Third-Party Claim resulting from the Indemnifying Person's liability to
        the third-party claimant and all related Expenses.

               (ii) If the Indemnifying Party gives the foregoing notice, it
        shall have the right to undertake, conduct and control, through counsel
        reasonably acceptable to the Indemnified Person, and at the Indemnifying
        Party's sole expense, the conduct and settlement of such claim,
        proceeding or suit, and the Indemnified Person shall cooperate with the
        Indemnifying Party in connection therewith; provided, however, that




                                       16
<PAGE>   17

                      (A) the Indemnifying Party shall not thereby permit any
               lien, encumbrance or other adverse legal or equitable charge to
               thereafter attach to any asset of the Indemnified Person;

                      (B) the Indemnifying Party shall not thereby permit any
               injunction against the Indemnified Person, except for injunctions
               that prohibit continuing Infringements;

                      (C) the Indemnifying Party shall permit the Indemnified
               Person and counsel chosen by the Indemnified Person and
               reasonably acceptable to the Indemnifying Party to monitor such
               conduct or settlement and shall provide the Indemnified Person
               and such counsel with such information regarding such claim,
               proceeding or suit as either of them may reasonably request
               (which request may be general or specific), but the fees and
               expenses of such counsel shall be borne by the Indemnified
               Person, unless (1) the Indemnifying Party and the Indemnified
               Person shall have mutually agreed to the retention of such
               counsel, or (2) the named parties to any such claim, proceeding
               or suit include the Indemnified Person and the Indemnifying
               Party, and in the reasonable opinion of counsel to the
               Indemnified Person, representation of both parties by the same
               counsel would be inappropriate due to actual or likely conflicts
               of interest between the Indemnified Person and the Indemnifying
               Party, in either of which cases the reasonable fees and
               disbursements of counsel for such Indemnified Person shall be
               reimbursed by the Indemnifying Party to the Indemnified Person if
               the Indemnifying Party is ultimately held liable, or if the
               Indemnifying Party is able to recover such fees and disbursements
               where the Indemnified Party is not so able.

               (iii) In no event shall the Indemnifying Party, without the prior
        written consent of the Indemnified Person, settle or comprise any claim
        or consent to the entry of any judgment that does not include as an
        unconditional term thereof the giving by the claimant or the plaintiff
        to the Indemnified Person a release from all liability (or covenant not
        to sue) in respect of such claim.

               (iv) If the Indemnifying Party shall not have undertaken the
        conduct and control of the defense of any claim, suit or proceeding as
        provided above, the Indemnifying Party shall nevertheless be entitled
        through counsel chosen by the Indemnifying Party and reasonably
        acceptable to the Indemnified Person to monitor the conduct or
        settlement of such claim by the Indemnified Person, and the Indemnified
        Person shall provide the Indemnifying Party and such counsel with such
        information regarding such action or suit as either of them may
        reasonably request (which request may be general or specific), but all
        costs and Expenses incurred in connection with such monitoring shall be
        borne by the Indemnifying Party, unless the Indemnified Party is able to
        recover such costs and Expenses where the Indemnifying Party is not so
        able.

        (f)    Settlement of Third-Party Claims by the Indemnified Person.

               (i) Provided that the Indemnifying Party is contesting a claim,
        suit or proceeding in good faith, the Indemnified Person shall not pay
        or settle any such claim, proceeding or suit. Notwithstanding the
        foregoing, the Indemnified Person shall have the right to pay or settle
        any such claim, proceeding or suit while the Indemnifying Party is
        contesting such claim, proceeding or suit in good faith; provided,
        however, that in such event, the Indemnified Person shall waive any
        right to indemnity therefor by the Indemnifying Party, and no amount in
        respect thereof shall be claimed as a Third-Party Claim or Expense under
        this Section 10.

               (ii) If the Indemnifying Party shall not have undertaken the
        conduct and control of the defense of any claim, suit or proceeding as
        provided above, the Indemnified Person, on not less than thirty (30)
        days prior written notice to the Indemnifying Party, may make settlement
        (including payment in full) of such claim, and such settlement shall be
        binding upon the Indemnified Person and the Indemnifying Party, unless
        within such 30-day period the Indemnifying Party shall have requested
        the Indemnified Person to contest such claim at the expense of the
        Indemnifying Party. In such event, the Indemnified Person shall promptly
        comply with such request, and the Indemnifying Party shall have the
        right to direct the defense of such claim or any litigation based
        thereon subject to all of the conditions of this Section 10.
        Notwithstanding anything in this Section 10 to the contrary, if the
        Indemnified Person advises the Indemnifying Party that it has determined
        to make settlement of a claim, the Indemnified Person shall have the
        right to do so at its own cost and expense, without any requirement to
        contest such claim at the request of the Indemnifying Party, but without
        any right under the provisions of this Section 10 for indemnification by
        the Indemnifying Party.

               (iii) In no event shall the Indemnified Party pay or settle any
        such claim, proceeding or suit on terms that:

                      (A) permit any lien, encumbrance or other adverse legal or
               equitable charge to thereafter attach to any asset of the
               Indemnifying Party; or

                      (B) permit any injunction against the Indemnifying Party,
               except for injunctions that prohibit continuing Infringements.

        (g) Further Requirements for Indemnification Except as may be expressly
provided otherwise in this Agreement, no Indemnifying Party shall be required to
defend or indemnify any Indemnified Person for any Third-Party Claims or
Expenses, to the extent that such Third-Party Claims or Expenses are finally
adjudged to have been caused by the negligence, gross negligence, or willful
misconduct of the Indemnified Person. Each Party agrees to cooperate with the
defense of a Third Party Claim and to take such actions as the Indemnifying
Party may reasonably request in order to reduce or eliminate exposure to a Third
Party Claim.

        11.    LIMITATION OF LIABILITY; NO THIRD PARTY BENEFICIARIES

        (a) Limitation of Liability. IN NO EVENT SHALL EITHER PARTY BE LIABLE TO
THE OTHER FOR ANY SPECIAL, INCIDENTAL, PUNITIVE, STATUTORY OR CONSEQUENTIAL
DAMAGES OR ANY MULTIPLE OF ACTUAL DAMAGES, WHETHER BASED ON BREACH OF CONTRACT,
TORT (INCLUDING NEGLIGENCE), OR OTHERWISE, AND WHETHER OR NOT THAT PARTY HAS
BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.

        (b) No Third Party Beneficiaries. This Agreement does not confer upon
any person, and nothing expressed or referred to in this Agreement shall be
construed to give any person, other than the Parties to this Agreement, any
legal or equitable right, remedy, or claim under or with respect to this
Agreement or any provision of this Agreement, except and only to the extent
provided in Section 10 to the Optimum Indemnified Parties and the CheMatch
Indemnified Parties. This Agreement and all of its provisions and conditions are
otherwise for the sole and exclusive benefit of the Parties hereto and their
respective successors and assigns.

        (c) Neither Party accepts any liability for or arising out of the
services offered or provided by the other Party.

        12.    TERMINATION

        (a) By Agreement. This Agreement may be terminated at any time by the
written agreement of the Parties.

        (b) Breach. This Agreement may be terminated by either Party upon thirty
(30) days written notice to the other in the event of a material breach of any
material provision of this Agreement which remains uncured at the expiration of
such thirty (30) days; provided, however, that only the non-breaching Party
shall have the right to terminate this Agreement under this Section 12(b); and
provided, further, that the failure of a Party to meet its obligations set forth
in Section 6 of this Agreement or in the Standards by the dates set forth
therein shall not constitute a material breach of a material provision of this
Agreement so long as such Party is diligently pursuing and continues to
diligently pursue fulfillment of such obligations.

        13.    INTELLECTUAL PROPERTY RIGHTS

        (a) CheMatch hereby grants a non-exclusive, non-transferable, worldwide
license to Optimum to use CheMatch's trade names, logos and trademarks solely
for purposes of effecting the transactions contemplated by this Agreement,
subject to the prior written approval of CheMatch, which approval shall not be
unreasonably withheld or delayed. CheMatch may revoke this license by giving ten
(10) days written notice of revocation to Optimum. Optimum hereby grants a
non-exclusive, non-transferable, worldwide license to CheMatch to use Optimum's
trade names, logos and trademarks solely for purposes of effecting the
transactions contemplated by this Agreement, subject to the prior written
approval of Optimum, which approval shall not be unreasonably withheld or
delayed. Optimum may revoke this license by giving ten (10) days written notice
of revocation to CheMatch. Notwithstanding the foregoing,


                                       19
<PAGE>   20

neither Party may use the other Party's marks in any manner that might be deemed
to create a unitary composite mark.

        (b) Other than as expressly set forth in this Agreement, CheMatch shall
have no right to use the marks, trade names or other proprietary rights of
Optimum without the prior written approval of Optimum. Other than as expressly
set forth in this Agreement, Optimum shall have no right to use the marks, trade
names or other proprietary rights of CheMatch without the prior written approval
of CheMatch.

        14.    PUBLICITY

        Neither Party shall make, without the approval of the other, any press
release or other public announcement concerning the Alliance or the transactions
contemplated by this Agreement, except to the extent that a Party is obligated
by law or the rules of any stock exchange to make such a press release or
announcement. In such case, the other Party shall be advised thereof, and the
Parties shall use their best efforts to cause a mutually agreeable release or
announcement to be issued. For the avoidance of doubt, the foregoing shall not
preclude communications or disclosures necessary to implement the provisions of
this Agreement or to comply with accounting and Securities and Exchange
Commission disclosure obligations.

        15.    GOVERNING LAW; JURISDICTION

        (a) Governing Law. This Agreement shall be governed by, and in
accordance with, the internal laws of the State of New York, without giving
effect to the conflict of laws principles thereof.

        (b) Jurisdiction. Each Party agrees (i) that any action, dispute or
proceeding relating to this Agreement shall be brought in the state district
courts of Harris County, Texas and freely submits to the jurisdiction of the
state district courts of Harris County, Texas, (ii) that it freely waives any
right to, and will not, oppose any such action or proceeding in the state
district courts of Harris County, Texas on the basis that the jurisdiction is
not a convenient forum, and (iii) not to oppose the enforcement against it in
any other jurisdiction of any judgement or order properly obtained from such a
Texas court.

        16.    NOTICES

        All notices or other communications provided for or permitted to be
given under this Agreement shall be in writing and shall be given either by

        17.    ARBITRATION

        Except for disputes relating to the provisions of Section 4 of this
Agreement or to issues of proprietary rights, including, but not limited to,
intellectual property and confidentiality, any dispute not resolved by amicable
resolution will be governed exclusively and finally by arbitration. Such
arbitration will be conducted by the American Arbitration Association ("AAA") in
New York and will be initiated and conducted in accordance with the Commercial
Arbitration Rules ("Commercial Rules") of the AAA, including the AAA
Supplementary Procedures for Large Complex Commercial Disputes ("Complex
Procedures"), as such rules will be in effect on the date of delivery of a
demand for arbitration ("Demand"), except to the extent that such rules are
inconsistent with the provisions set forth herein. Notwithstanding the
foregoing, the Parties may agree in good faith that the Complex Procedures will
not apply in order to promote the efficient arbitration of disputes where the
nature of the dispute, including without limitation the amount in controversy,
does not justify the application of such procedures. The arbitration panel will
consist of three (3) arbitrators. Each Party will name an arbitrator


                                       21
<PAGE>   22

within ten (10) days after the delivery of the Demand. The third arbitrator,
selected by the first two, will be a neutral participant, with no prior working
relationship with either Party. The arbitration shall be conducted on
consecutive business days until completed unless all Parties agree otherwise,
and the arbitrators shall use their best efforts to expedite the arbitration so
that the entire arbitration shall be completed within six (6) months of the
delivery of the Demand. The Federal Arbitration Act, 9 U.S.C. Secs. 1-16, and
not state law, will be used to determine whether a dispute hereunder can be
resolved by arbitration. The Federal Rules of Evidence will apply in toto. The
arbitrators may enter a default decision against any Party who fails to
participate in the arbitration proceedings. The arbitrators shall have the
authority to award compensatory damages only and shall have no authority to
award incidental, consequential, exemplary or punitive damages. The award
rendered by the arbitrators will be final, binding and non-appealable, and
judgment upon such award may be entered by any court of competent jurisdiction.

        18.    MISCELLANEOUS

        (a) No Partnership; Independent Contractors. Nothing contained in this
Agreement is intended or shall be construed to create any partnership, joint
venture, or association between the Parties, and any inferences to the contrary
are hereby expressly negated. The relationship of the Parties is and shall at
all times be solely that of independent contractors. No agency, employment or
any fiduciary relationship is created by this Agreement. Although the Parties
will, inter alia, link their websites, cross-promote their services and pay each
other a percentage of certain revenues under this Agreement, the Parties intend
that the Alliance formed by this Agreement is only in the nature of a referral
or broker arrangement. Neither Party shall do anything that has the effect of
creating an obligation by the other Party to a third party.

        (b) Assignment. Neither this Agreement, nor any rights or obligations
arising from it, may be assigned, delegated, transferred or subcontracted by
either Party without the express written consent of the other, which will not be
unreasonably withheld or delayed. Notwithstanding the foregoing, either Party
may assign, delegate, transfer or sub-contract any of its rights or obligations
arising under this Agreement to an affiliate without obtaining the other's
express written consent; provided, however, that no such assignment, transfer,
delegation or sub-contract shall relieve such Party of its obligations under
this Agreement.

        (c) Force Majeure. Neither Party shall be liable for damages and costs
to the other Party arising out of delays or failures to perform its obligations
under this Agreement if such delays or failures result from causes beyond its
reasonable control. Notice of any such delays or failures and explanation of
their causes must be given to the other within five (5) days of the occurrence.

        (d) Entire Agreement. This Agreement constitutes the entire agreement
between the Parties pertaining to the subject matter hereof and supersedes all
prior and contemporaneous agreements, understandings, negotiations and
discussions, whether oral or written, of the Parties, and there are no
warranties, representations or other agreements between the Parties in
connection with the subject matter hereof except as specifically set forth
herein or contemplated hereby. Except as otherwise provided herein, no
supplement, modification or waiver of this


                                       22
<PAGE>   23

Agreement shall be binding unless it shall be specifically designated to be a
supplement, modification or waiver of this Agreement and shall be executed in
writing by both of the Parties.

        (e) Waiver. No failure on the part of a Party hereto to exercise, and no
delay in its exercise of, any right, power or privilege hereunder shall operate
as a waiver thereof. No single or partial exercise by a Party of any right,
power or privilege hereunder shall preclude any other or further exercise
thereof or the exercise of any other right, power or privilege.

        (f) Headings. The use of headings in this Agreement is for convenience
only and shall not affect the construction or interpretation of this Agreement.

        (g) Exhibits. Each Exhibit referred to in this Agreement is a part of,
and hereby incorporated into, this Agreement. Any reference to "this Agreement"
shall be deemed to include the Exhibits hereto.

        (h) Severability. If one or more of the provisions of this Agreement are
at any time found to be invalid by a court, tribunal or other forum of competent
jurisdiction, or otherwise rendered unenforceable, such decision shall not have
the effect of invalidating or voiding the remainder of this Agreement. This
Agreement shall be deemed amended by modifying or severing such provisions as
necessary to render it valid, legal and enforceable while preserving its intent,
or if that is not possible, by substituting another provision that is valid,
legal and enforceable which materially effectuates the Parties' intent. Any such
invalid or unenforceable provision or provisions shall be severable from this
Agreement, so that the validity or enforceability of the remaining provisions of
this Agreement, or the validity of the provision(s) in question in any other
jurisdiction, shall not be affected thereby.

        (i) Bankruptcy. Each Party must notify the other if it becomes insolvent
or enters into any bankruptcy or insolvency proceedings.

        (j) Survival. The provisions of Sections 7, 9 and 10 shall survive the
termination of this Agreement for whatever reason, subject to any applicable
statute of limitations and subject to any provisions contained in such sections.
