Attention: Richard J. Lubasch

Mr. Lubasch:

         This letter agreement is to confirm that the parties agree that
as of the date hereof, with respect to the 10.75% Unsecured Convertible PIK
Notes due 2011, dated October 15, 2001, and any additional 10.75% Unsecured
Convertible PIK Notes (collectively, the "Notes"), issued, or to be issued,
respectively, CoreComm Limited and/or CoreComm Holdco, Inc. ("Holdco") as
obligors in favor of NTL Incorporated ("NTL");

         CoreComm Limited and CoreComm Holdco hereby exercise their right under
         Section (9) of the Notes such that, following the completion of
         Holdco's exchange offer to the holders of CoreComm Limited common stock
         to exchange their shares of CoreComm Limited common stock for shares of
         Holdco common stock, the convertibility feature of the Notes will be
         altered so that rather than the Notes being convertible into shares of
         CoreComm Limited common stock, they will become convertible into shares
         of Holdco common stock. At that time, the conversion prices of each
         Note will be equitably adjusted by dividing the conversion price then
         in effect by the exchange ratio at the completion of the exchange offer
         for CoreComm Limited common stock (for example, an initial exchange
         ratio of 1/38.9 and a conversion price of $1.00 would result in a new
         conversion price of $38.90 for each share of CoreComm Holdco common
         stock, as may be adjusted from time to time as set forth in the Notes),
         as may thereafter be adjusted pursuant to the Notes. NTL hereby agrees
         not to exercise its rights to convert the Notes into CoreComm Limited
         common stock until August 5, 2002 (unless that right has previously
         ceased as a result of the completion of the exchange offer and the
         change in the convertibility feature). In the event that Holdco does
         not complete the exchange offer for CoreComm Limited common stock by
         August 5, 2002, the conversion feature of the Notes will remain into
         CoreComm Limited common stock on its original terms. This letter
         agreement is to be governed by the laws of the State of New York.

Mr. Lubasch:

         This letter agreement is to confirm that the parties hereto agree that
as of the date hereof, with respect to the 10.75% Unsecured Convertible PIK Note
due 2011, dated April 12, 2001 (the "Note"), issued by CoreComm Limited and
CoreComm Holdco, Inc. ("Holdco") as obligors in favor of NTL Incorporated
("NTL");

         CoreComm Limited and CoreComm Holdco hereby exercise their right under
         Section (9) of the Note such that, following the completion of Holdco's
         exchange offer to the holders of CoreComm Limited common stock to
         exchange their shares of CoreComm Limited common stock for shares of
         Holdco common stock, the convertibility feature of the Note will be
         altered so that rather than the Note being convertible into shares of
         CoreComm Limited common stock, it will become convertible into shares
         of Holdco common stock. At that time, the conversion prices will be
         equitably adjusted by dividing the conversion prices by the exchange
         ratio at the completion of the exchange offer for CoreComm Limited
         common stock (for example, an initial exchange ratio of 1/38.9 and a
         conversion price of $1.00 would result in a new conversion price of
         $38.90 for each share of CoreComm Holdco common stock, as may be
         adjusted from time to time as set forth in the Note), as may thereafter
         be adjusted pursuant to the Note. NTL hereby agrees not to exercise its
         rights to convert the Note into CoreComm Limited common stock until
         August 5, 2002 (unless that right has previously ceased as a result of
         the completion of the exchange offer and the change in the
         convertibility feature). In the event that Holdco does not complete
         the exchange offer for CoreComm Limited common stock by August 5, 2002,
         the conversion feature of the Note will remain into CoreComm Limited
         common stock on its original terms. This agreement is to be governed by
         the laws of the State of New York.

respect to responsibilities, obligations, and liabilities associated with the

         The Sheboygan River and Harbor Superfund Site contains Pollutants, is
subject to Remediation, and may give rise to other claims and liabilities under
Environmental Law, all as defined herein.

         The United States Environmental Protection Agency ("EPA") has issued a
Record of Decision that sets forth the selected remedies for the Site.

         Tecumseh desires to transfer and assign, and PRS desires to assume,
certain responsibilities, obligations, and liabilities in connection with the
Site as provided in this Agreement, including but not limited to all
responsibilities, obligations, and liabilities for Remediation and Remediation
Costs.

         The Parties intend that Remediation Cost Cap insurance issued by Chubb
Financial Solutions division of Federal Insurance Company for itself and as
manager of the member insurers of the Chubb Group of Insurance Companies
("Chubb") and funded by Tecumseh shall provide remediation cost insurance
coverage to the Parties in the amount of $100,000,000. The Parties further
intend that Environmental Site Liability insurance issued by Chubb and funded by
Tecumseh shall provide environmental site liability insurance coverage to the
Parties in the amount of $20,000,000, subject to certain deductibles payable by
PRS.

         The Parties further intend that the Remediation Cost Cap and
Environmental Site Liability insurance policies will provide financial assurance
for the costs of completing the responsibilities, obligations, and liabilities
transferred and assigned by Tecumseh and assumed by PRS under this Agreement.

accepts, assumes, and agrees to be responsible for, the Environmental
Liabilities and Other Assumed Liabilities.

                  (b) PRS hereby releases Tecumseh and its predecessors,
successors, affiliates, subsidiaries, lessees and assigns, and their respective
officers, directors, shareholders, employees, agents, and representatives, from
Losses arising out of, resulting from, or associated with Environmental
Liabilities or Other Assumed Liabilities, except that such release shall not
operate to the extent of Losses resulting from Tecumseh's failure to comply with
its obligations and representations, warranties, and covenants under this
Agreement.

                  (c) If PRS becomes a signatory to the Consent Decree, nothing
in the Consent Decree shall release PRS from any liability it may have to
Tecumseh as a result of the performance of work under the Consent Decree in the
event of and prior to PRS's replacement pursuant to the Consent Decree, or any
other liability that PRS may have to Tecumseh under this Agreement.

         3. INDEMNIFICATION. PRS shall hold harmless, indemnify, and defend
Tecumseh and its predecessors, subsidiaries, affiliates, successors, lessees,
assigns, officers, directors, shareholders, and employees, and each of them,
from and against:

                  (a) any and all Losses arising out of, resulting from, or
associated with (i) any Environmental Liabilities; (ii) any Other Assumed
Liabilities; (iii) a breach by PRS of the terms of this Agreement, (iv) any
failure by PRS to perform its obligations pursuant to either of the Chubb
Policies, or any act or omission by PRS pursuant to which Chubb denies coverage
under either of the Chubb Policies, or cancels either of the Chubb Policies, (v)
any acts, omissions, negligence, or misconduct of PRS or its officers, agents,
employees, or subcontractors, or (vi) any violation by PRS of the terms of the
Sheboygan River and Harbor Superfund Site Consent Decree; and

                  (b) any and all Losses arising out of, resulting from, or
associated with Bodily Injury or Property Damage to the extent (but only to the
extent) caused by the acts, omissions, negligence or misconduct of PRS or its
officers, agents, employees, or subcontractors.

         PRS agrees that its failure to keep the Chubb Policies in force as
provided herein shall render PRS liable to Tecumseh for the full amount of
coverage and defense costs provided by the relevant Chubb Policy in the event of
a loss covered by the policy for which Tecumseh is alleged to be responsible.

         4. PERFORMANCE BY TECUMSEH.

                  (a) On or before the date of execution of this Agreement,
Tecumseh shall purchase the Chubb Policies and provide a copy of the authorized

acknowledge and agree that, apart from Tecumseh's obligation under Paragraph
4(a), there shall be no further payment or compensation from Tecumseh to PRS or
to Chubb in connection with this Agreement.

                  (c) Tecumseh hereby assigns to PRS any rights it may have to
obtain indemnification, cost recovery, contribution, damages, or any other form
of payment from any Third Party other than Chubb for Environmental Liabilities
or Other Assumed Liabilities assumed by PRS under this Agreement. Tecumseh shall
timely provide information reasonably requested by PRS for purposes of obtaining
such recovery or payment. PRS agrees to notify Tecumseh and the United States
(as provided in the Consent Decree) of any contribution lawsuit or negotiations
and to give Tecumseh and the United States advance notice of any proposed
settlement. The Parties agree to use good faith efforts to resolve any issues
that may arise with respect to such future settlements.

                  (d) On reasonable request, Tecumseh shall provide to PRS, at
no cost to PRS, any non-privileged information, plans, and documents in
Tecumseh's possession relating to the Site that were developed or created prior
to the Effective Date, including but not limited to any data, studies, plans, or
design documents. On reasonable request, Tecumseh will assist PRS in obtaining
interviews with current Tecumseh personnel as required to implement the
performance standards set forth in the ROD, the Consent Decree, or any other
environmental standard ordered or approved by any relevant Government Authority.
On reasonable request, Tecumseh will assist PRS in obtaining interviews with
current Tecumseh personnel, and will attempt to assist PRS in obtaining
interviews with former Tecumseh personnel, as may be necessary in PRS's
discretion to ascertain other potentially liable parties.

                  (e) Tecumseh shall give PRS access at all reasonable times to
any portions of the Site owned by Tecumseh as needed for PRS, as determined by
PRS, to comply with its obligations under this Agreement. Tecumseh will also
provide access to the Tecumseh Property to the United States and the State of
Wisconsin as required under the Consent Decree. Tecumseh agrees to cooperate
with PRS in the preparation and filing of any documents relating to access to,
and institutional controls on, the Tecumseh Property that are required under the
Consent Decree. Tecumseh shall not have any other obligation under this
Agreement to secure site access or to obtain institutional controls. Tecumseh
will reasonably cooperate with PRS to enable PRS to carry out its obligations
hereunder with respect to Tecumseh Property.

                  (f) Subject to Tecumseh's right to take reasonable steps to
ensure that the rights of Tecumseh and the obligations of PRS under this
Agreement are fulfilled, Tecumseh shall not interfere with PRS's efforts to
conduct the Remediation and otherwise address the Environmental Liabilities and
Other Assumed Liabilities assumed by PRS under this Agreement. Until its
business operations at the Tecumseh Property have ceased, which Tecumseh
anticipates will occur by November 1, 2003, Tecumseh shall use good faith
efforts to resolve any conflict between Tecumseh's need to carry out its
business operations and PRS's need to fulfill its obligations under this
Agreement.

acceptance of liability set forth in Paragraph 2 above, PRS's obligations for
Environmental Liabilities and Other Assumed Liabilities include, but are not
limited to:

                  (a) Assuming the responsibility for, and performance and
completion of, Remediation of the Site in accordance with the ROD, including but
not limited to all of the response actions and performance standards outlined in
the ROD and the Consent Decree and any other standard ordered or approved by a
relevant Government Authority, and including the performance of the
investigations, studies, negotiations, document preparation, filings and
interactions, engineering design, permitting, removal actions, remedial actions,
operations, maintenance, and monitoring, including periodic reviews required by
42 U.S.C. ss.9621(c), and all other response actions necessary to implement the
ROD and to comply with the Consent Decree, including payment of regulatory
agency future oversight costs;

                  (b) Pursuing diligently and in good faith, with Tecumseh and
the United States, the addition of provisions to the pending draft Consent
Decree for Upper River Work and any future Consent Decree that would, generally
consistent with the language proposed to EPA in November 2002:

                           (i) add PRS as a signatory along with Tecumseh;

                           (ii) have EPA pursue PRS in the first instance, and
not Tecumseh, in the event of any noncompliance by PRS with its obligations
under the Consent Decree; and

                           (iii) enable EPA to find PRS in default and require
Tecumseh to find a substitute contractor to take over from PRS in the event that
EPA determines that PRS has engaged in serious noncompliance or certain other
conditions occur;

                  (c) Becoming a signatory to the Consent Decree, if appropriate
and with the approval of Tecumseh, EPA, and the U.S. Department of Justice, and
on terms approved by PRS, which approval shall not be unreasonably withheld;

                  (d) Assuming the responsibility for, and performance and
completion of, all Tecumseh obligations under the Consent Decree as if PRS had
signed the Consent Decree, in the event that PRS does not become a signatory but
approves of the terms of the Consent Decree, which approval shall not be
unreasonably withheld;

                  (e) Retaining a qualified Supervising Contractor (as defined
in the Consent Decree) or other prime contractor to perform or manage any
Remediation regarding the Site, with qualifications to include demonstrated
experience with respect to sediment remediation and satisfaction of the criteria
set forth in the Consent Decree for the selection of a Supervising Contractor;

                  (f) Paying all Remediation Costs;

                  (g) Complying with all of its responsibilities as the Named
Insured and an "Insured" under the Chubb Policies;

                                     - 7 -

<PAGE>

                  (h) Coordinating and cooperating with EPA and the State of
Wisconsin, and any other involved government agencies;

                  (i) Negotiating, executing (to the extent permitted by
Government Authority), and assuming complete operational and financial
responsibility for any and all consent decrees, administrative orders on
consent, or unilateral administrative orders issued after the Effective Date
that are required to complete the requirements of the ROD;

                  (j) Timely providing to Tecumseh notice and the opportunity to
participate in negotiation of, and to sign, any consent decrees, administrative
orders on consent, or other settlements after the Effective Date resolving any
Third Party claims against PRS or Tecumseh arising from or relating to the Site;

                  (k) Reasonably cooperating with Tecumseh in carrying out its
obligations hereunder with respect to the Tecumseh Property. During Tecumseh's
business operations at the Tecumseh Property, which Tecumseh anticipates will
cease by November 1, 2003, PRS shall not interfere with such business
operations, although Tecumseh shall take reasonable steps to cooperate with PRS
to enable it to fulfill its obligations hereunder with respect to the Tecumseh
Property. During this period, PRS shall use good faith efforts to resolve any
conflict between Tecumseh's need to carry out its business operations and PRS's
need to fulfill its obligations under this Agreement, and if the conflict cannot
be resolved despite the good faith efforts of both Parties, PRS shall not be
subject to liability hereunder to the extent that it is unable to fulfill its
obligations due to such conflict or due to any agreement or contract into which
Tecumseh has entered relating to Tecumseh's business operations at the Tecumseh
Property;

                  (l) Providing written notice to Tecumseh:

                           (i) of any material notice or communication from EPA
concerning negotiations on an Administrative Order on Consent or Consent Decree,
or concerning a unilateral Administrative Order under Section 106 of CERCLA,
relating to part or all of the Site;

                           (ii) within ten (10) days of the receipt of any
notice of noncompliance issued by EPA under the Consent Decree; and

                           (iii) within five (5) days of the receipt of any
notice of default issued by the EPA under the Consent Decree;

                  (m) Providing copies of final documents to Tecumseh at the
time they are submitted to EPA;

                  (n) To the extent PRS decides that such a modification is
desirable, PRS is solely responsible, at its sole expense, for obtaining any
modifications in the remedy for the Site selected in the ROD;

                  (o) Developing, proposing, and implementing institutional
controls or land use restrictions as appropriate to fulfill PRS's obligations
and responsibilities under this Agreement, to the extent that such controls or
restrictions do not unreasonably interfere with Tecumseh's business operations
at the Tecumseh Property;

                                     - 8 -
<PAGE>

                  (p) PRS shall also maintain, at its sole cost and expense, the
following insurance coverages, and will assure that any contractor that it
retains in connection with the Site shall also maintain such insurance
coverages:

                           (i) Commercial General Liability insurance alone or
in combination with Commercial Umbrella insurance with a limit of not less than
$10,000,000 each occurrence covering liability arising from premises,
operations, independent contractors, products-completed operations, personal
injury and advertising injury, and liability assumed under an insured contract
(including the tort liability of another assumed in a business contract);

                           (ii) Business Automobile Liability insurance alone or
in combination with Commercial Umbrella insurance covering any auto or vehicle
(including owned, hired, and non-owned autos or vehicles), with a limit of not
less than $1,000,000 each accident;

                           (iii) Professional Liability insurance with a minimum
limit of not less than $5,000,000; and

                           (iv) Workers' compensation with statutory limits and
Employers' Liability limits of not less than $1,000,000 each accident for bodily
injury by accident or $1,000,000 for each employee for bodily injury by disease;

                  (q) On or before the date of execution of this Agreement and
annually thereafter, PRS shall submit to Tecumseh a certificate or certificates
for each required insurance referenced above certifying that such insurance is
in full force and effect and setting forth the information required below.
Additionally, PRS shall furnish to Tecumseh, within 30 days before the
expiration date of the coverage of each required insurance set forth above, a
certificate or certificates containing the information required below and
certifying that such insurance has been renewed and remains in full force and
effect.

                  (r) All insurance policies described in Paragraph 5(p) above
shall: (i) name Tecumseh as an Additional Insured (this requirement shall not
apply to workers' compensation insurance, employers' liability insurance, or
professional liability); (ii) provide for not less than 30 days' prior written
notice to Tecumseh by registered or certified mail of any cancellation,
non-renewal, or material reduction in coverage; (iii) include a waiver of
subrogation in favor of Tecumseh; and (iv) provide that such required insurance
hereunder is the primary insurance and that any other similar insurance that
Tecumseh may have shall be deemed in excess of such primary insurance.

         6. REPRESENTATIONS, WARRANTIES, AND COVENANTS OF PRS.

                  (a) PRS acknowledges that the Site is a so-called "Superfund"
site listed on the National Priorities List, 40 C.F.R. Part 300, Appendix B,
that the ROD has been issued for the Site, and that ongoing response actions to
implement the ROD are currently underway at the Site.

                  (b) PRS acknowledges that it has satisfied itself as to the
general nature and location of the Site and as to the general and local
conditions, particularly those bearing upon (i) Pollutants, (ii) Remediation
requirements, (iii) clean up and disposal requirements,

                                     - 9 -
<PAGE>
(iv) handling and storage of materials, including, without limitation,
Pollutants, (v) availability of labor, (vi) security requirements, (vii) water,
(viii) electric power, (ix) roads, (x) the character, quality and quantity of
surface and subsurface materials to be encountered, (xi) equipment and
facilities needed preliminary to and during the prosecution of the work, and
(xii) uncertainties of weather.

                  (c) PRS represents and warrants that it has the financial
resources, including access to the Chubb Policies, to execute diligently the
Remediation of the Site in accordance with the ROD, including but not limited to
all of the response actions and performance standards outlined in the ROD and
the Consent Decree, even if the scope of Remediation or Remediation Costs
exceeds PRS's estimate thereof, and PRS shall use such resources as necessary to
fulfill all of its obligations under this Agreement.

                  (d) PRS represents and warrants that it is not a party to any
other existing or previous agreement or contract that would be inconsistent with
or interfere with the performance of its obligations and responsibilities under
this Agreement, and that it will not enter into any such agreement or contract
after the Effective Date.

                  (e) PRS represents and warrants that it has reviewed all
records, to the extent PRS understands such records to be relevant, of Tecumseh,
EPA and the State of Wisconsin, and of any other Government Authority,
concerning the Site, and that it is familiar with the Pollutants, Natural
Resources, and all other relevant conditions at the Site. PRS represents and
warrants that it assumes the risk of all conditions at the Site and, regardless
of the exact nature of such conditions, or the expense or difficulty of
performing the Remediation with respect to same, will fully perform and complete
the Remediation required by Government Authorities for the Site.

                  (f) PRS represents and warrants that it has the
qualifications, expertise, and experience needed to accomplish all required
Remediation at the Site consistent with this Agreement. PRS further covenants
and agrees that it shall perform the Remediation of the Site in compliance with
this Agreement and Environmental Law, and the standards of care and diligence
normally practiced by nationally recognized firms performing services of a
similar nature. In the event that the performance of any portion of the
Remediation of the Site fails to comply with the representations and warranties
in this Paragraph 6 and such failure results in additional requirements or
actions from Government Authorities, PRS shall, at its sole expense, redo such
portions of the Remediation as necessary to comply with the additional
requirements or actions of the Governmental Authorities and the representations
and warranties provided herein.

                  (g) PRS represents and warrants that it has provided Chubb
with access to all of the information in PRS's possession concerning the
Pollutants and other conditions at the Site and all information sought by Chubb
concerning the Site to the extent available to PRS.

                  (h) PRS represents and warrants that it has complied with, and
agrees that it will continue to comply in a timely fashion with, all obligations
and responsibilities of the Named Insured under the Chubb Policies, including
all provisions relating to notification of, provision of information to, and
reporting to Chubb.

                                     - 10 -
<PAGE>

                  (i) PRS covenants and agrees that after the Effective Date,
PRS shall have responsibility and liability (relative to Tecumseh) for, and
shall be responsible for signing in its own name all manifests for, all wastes,
garbage, refuse, sludge, residues and other discarded materials removed from the
Site (collectively, "Wastes"), and shall be liable for the treatment, storage
and disposal of such Wastes. PRS shall cause all Wastes, regardless of their
form, that are transported from the Site to any offsite location ("Offsite Waste
Facility"), whether for treatment, recycling, storage, disposal, or other
management, to be: (i) transported in a manner that complies with all applicable
requirements of Government Authorities, including without limitation, all
applicable Environmental Laws; and (ii) delivered to an Offsite Waste Facility
that maintains and is in substantial compliance with, at the time of delivery,
all applicable licenses, permits, authorizations, certificates and approvals to
accept such Wastes.

                  (j) PRS represents and warrants that it shall not seek any
changes in the remedy for the Site selected in the ROD that could materially and
adversely affect the potential liability of Tecumseh under Environmental Law,
except with Tecumseh's prior written consent, which consent shall not be
unreasonably withheld. For the purposes of this Paragraph 6(j), Tecumseh's
withholding of consent shall not be deemed unreasonable where the change sought
by PRS could increase Tecumseh's potential liability for Natural Resource
Damages. Nothing in this Paragraph 6(j) shall be construed to affect, as between
PRS and Tecumseh, PRS's control and discretion in conducting the Remediation or
other cleanup efforts at the Site as may otherwise be provided in this
Agreement.

                  (k) Except as otherwise provided herein, PRS makes no
representations or warranties, express or implied, to Tecumseh with respect to
the matters covered by this Agreement.

         7. REPRESENTATIONS, WARRANTIES, AND COVENANTS OF TECUMSEH.

                  (a) Tecumseh represents and warrants that it has made
available for PRS's review copies of all material data and other information
concerning the Site that it has in its possession that were not otherwise
available to PRS as part of PRS's review of files and information in EPA's
possession regarding the Sheboygan River and Harbor Superfund Site.

                  (b) As long as PRS is in substantial compliance with its
obligations, representations, warranties, and covenants under this Agreement,
Tecumseh agrees and covenants that PRS will have sole discretion and control, as
between Tecumseh and PRS, to perform the Remediation and otherwise address the
Environmental Liabilities and Other Assumed Liabilities and that Tecumseh will
not interfere with PRS performance under this Agreement.

                  (c) Tecumseh agrees and covenants that it will not contest or
otherwise prevent any institutional control or land use restriction proposed by
PRS or otherwise required by Government Authority unless such control or
restriction may unreasonably interfere with Tecumseh's business operations at
the Tecumseh Property.

                  (d) Tecumseh represents and warrants that it is not a party to
any other existing or previous agreement or contract that would be inconsistent
with or interfere with the

                                     - 11 -
<PAGE>

performance of its obligations and responsibilities or PRS's obligations and
responsibilities under this Agreement, and will not enter into any such
agreement or contract after the Effective Date; provided, however, that this
representation and warranty does not include any agreements or contracts
relating to Tecumseh's operations at the Tecumseh Property.

                  (e) Tecumseh represents and warrants that it has made
available for Chubb's review, to the extent requested by Chubb, copies of all
material data and other information concerning the Site that Tecumseh has in its
possession that were not otherwise available to Chubb as part of Chubb's review
of files and information in EPA's possession regarding the Sheboygan River and
Harbor Superfund Site.

                  (f) Tecumseh represents and warrants that it shall not seek
any changes in the remedy for the Site selected in the ROD except with PRS's
prior written consent, which consent shall not be unreasonably withheld. For the
purposes of this Paragraph 7(f), PRS's withholding of consent shall not be
deemed unreasonable where the change sought by Tecumseh would increase the cost
or difficulty of complying with the ROD.

                  (g) Tecumseh represents and warrants that in 2001 the
following actions were taken at the Tecumseh Property: the Sediment Management
Facility was emptied of sediment and decontaminated and the steel walls were
scrapped, and the Confined Treatment Facility was emptied of sediment, the
primary liner was removed, and the integrity of the primary liner was visually
confirmed.

                  (h) Except as otherwise provided herein, Tecumseh makes no
representations or warranties, express or implied, to PRS with respect to the
matters covered by this Agreement, including but not limited to any
representations or warranties regarding the conditions at the Site or the extent
of Remediation necessary at the Site.

         8. INDEPENDENT CONTRACTOR.

         PRS is an independent contractor. PRS shall be solely responsible for
all of its practices, procedures, means, methods, equipment, facilities, and
protocols used in carrying out its obligations under this Agreement, for all
governmental fees and taxes imposed upon any services or tangible items that it
purchases or provides, and for payment of all compensation, benefits,
contributions, and taxes, if any, due its employees, agents, contractors, and
subcontractors. PRS agrees that any and all persons whom it may employ or whose
services it may retain in order to perform its obligations under this Agreement
shall remain PRS's employees or consultants exclusively. Neither PRS nor
Tecumseh, by this Agreement, intend that PRS or PRS's employees,
representatives, and agents shall be considered, or deemed to be, or acting as
employees of or joint venturers of Tecumseh. PRS shall not take any action or
make any omission that is inconsistent with its status as an independent
contractor.

Date.

                  (b) Tecumseh may, at its sole option, terminate this
Agreement, but only for the following reasons:

                           (i) PRS has ceased implementation of the work
contemplated by this Agreement, is seriously or repeatedly deficient or late in
its performance of such work, or is implementing such work in a manner which
presents a significant risk of causing an endangerment to human health or the
environment;

                           (ii) PRS has failed to cure a notice of violation
from EPA within the time allowed for such cure;

                           (iii) PRS has failed to substantially comply with
Environmental Laws in performing Remediation;

                                     - 13 -
<PAGE>

                           (iv) EPA has refused to work further with PRS and EPA
is not legally obligated to work with PRS on such matters;

                           (v) PRS has declared bankruptcy, or has become
bankrupt as a result of an involuntary bankruptcy filing, or has become or is
about to become insolvent;

                           (vi) PRS has failed to comply with its obligations
under either or both Chubb Policies in a manner that places the coverage for
Tecumseh under either or both Chubb Policies at risk; or

                           (vii) PRS has materially breached its obligations,
representations, warranties, or covenants under this Agreement.

                  (c) PRS may, at its sole option, terminate this Agreement, but
only for the following reasons:

                           (i) Tecumseh does not purchase the Chubb Policies
pursuant to the terms of this Agreement;

                           (ii) Tecumseh's actions or inactions void PRS's
coverage under either or both Chubb Policies; or

                           (iii) Tecumseh materially interferes with PRS's
ability to perform PRS's obligations under this Agreement when PRS is otherwise
in substantial compliance with its obligations, representations, warranties, and
covenants under this Agreement.

                  (d) In the event that Tecumseh has the grounds to terminate
this Agreement pursuant to this Paragraph 10, it may choose to proceed with one
or more of the following options: (i) exercise its rights under the Chubb
Policy; or (ii) seek any other remedy, including specific performance as set
forth in Paragraph 11.

                  (e) In order to terminate this Agreement pursuant to
Paragraphs 10(b) or (c), the Party seeking to terminate the Agreement must
provide the other Party with written notice of its intent to terminate and its
reason therefore. The other Party shall have 30 days in which to cure the
alleged default or to undertake activities necessary to correct the default if
the same cannot be completed within the 30-day period. So long as the other
party is diligently pursuing actions reasonably designed to effectuate a cure,
the Party seeking to terminate shall not be permitted to do so. The Agreement
may be terminated upon the failure of the other Party to cure the default or to
diligently pursue actions reasonably designed to effectuate a cure within the
30-day period.

         11. SPECIFIC PERFORMANCE. The Parties hereto recognize that PRS's
performance of its obligations under this Agreement is special, unique, and of
extraordinary character, and that Tecumseh will be irreparably injured if this
Agreement is not specifically enforced. Therefore, notwithstanding anything to
the contrary contained herein or otherwise, Tecumseh shall have the right to
enforce specifically PRS's performance under this Agreement. PRS waives the
defense in any such suit that Tecumseh has an adequate remedy at law, and PRS
will interpose no opposition, legal or otherwise, as to the propriety of
specific performance as a remedy. The

                                     - 14 -
<PAGE>

remedy of specific performance shall be in addition to, and not in lieu of, any
other remedies that Tecumseh may elect to pursue.

         12. SEVERABILITY. If any term or provision of this Agreement is
determined by a court of competent jurisdiction to be unenforceable, invalid, or
void, the validity of any other term or provision shall not be affected
adversely, and this Agreement shall continue to be binding on the Parties as if
said unenforceable, invalid, or void term or provision had not been included
herein. In the case of any such decision by a court of competent jurisdiction,
the remainder of this Agreement shall be interpreted to give as much meaning to
the intent of the invalidated portion or portions of the Agreement as allowed
under applicable law. In such a case, the Parties shall negotiate in good faith
an equitable modification of this Agreement or an adjustment in the relevant
provisions of this Agreement, with a view toward effectuating the original
intent and purpose of this Agreement.

         13. WAIVER/MODIFICATION. No waiver or modification of any provision of
this Agreement shall be effective unless such waiver or modification is in
writing and signed by the party against whom enforcement of the same is sought.
Failure to enforce any provision of this Agreement or to require at any time
performance of any provision hereof shall not be construed to be a waiver of
such provision, or to affect the validity of this Agreement or the right of any
party to enforce each and every provision in accordance with the terms hereof.
No waiver of any provision of this Agreement shall affect the right of Tecumseh
or PRS thereafter to enforce such provision or to exercise any right or remedy
available to it in the event of any other default involving such provision or
any other provision. Making payment or performing pursuant to this Agreement
during the existence of a dispute shall not be deemed to be and shall not
