                  SNSL hereby represents and warrants to WPS Ltd. as follows:

            4.1 Authority; Ownership of Stock; No Conflict or Violation. SNSL
has all necessary power and authority to own the NSMM Outstanding Shares and to
enter into, deliver and carry out its obligations under the Transaction
Documents. SNSL has taken all action necessary to consummate the transactions
contemplated thereby and to perform its obligations thereunder. Each of the
Transaction Documents to which SNSL is a party has been duly executed and
delivered by or on behalf of SNSL. Each Transaction Document to which SNSL is a
party is the legal, valid and binding obligation of SNSL, enforceable against
SNSL in accordance with its terms except as such enforcement may be limited by
bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and
similar laws affecting the enforceability of contractual obligations and
creditor's rights generally and by the application of equitable principles by
courts of competent jurisdiction sitting at law or in equity. SNSL owns of
record and beneficially all of the NSMM Outstanding Shares, free and clear of
all Encumbrances. SNSL does not own, of record or beneficially, any Equity
Interests of NSMM other than the NSMM Outstanding Shares. Upon the transfer on
the Closing Date by SNSL to WPS Ltd. of the NSMM Outstanding Shares in
accordance with Section 2.1 of this Agreement, WPS Ltd. will receive good title
to such shares, free and clear of all Encumbrances. Neither the execution and
delivery of the Transaction Documents


                                       -7-
<PAGE>   8
nor the consummation of the transactions contemplated thereby will result in the
violation by SNSL or any Acquired Company of any Legal Requirement.

            4.2 No Brokers; Agreements to Sell. Neither NSMM nor any Acquired
Company, nor any Representative or Affiliate of any of them, has any written or
oral agreement, arrangement or understanding with any Person which could result
in the obligation of WPS Ltd., or any Acquired Company to pay any finder's fee,
brokerage commission or similar payment in connection with any of the
transactions contemplated by the Transaction Documents. Except in connection
with this Agreement and the other Transaction Documents, neither NSMM nor SNSL
has any obligation, absolute or contingent, to any other Person to sell any NSMM
Outstanding Shares or any Equity Interest in Cribewell or to enter into any
agreement with respect thereto.

            4.3 Organization of SNSL; No Conflict or Violation. SNSL is duly
formed and validly existing as a limited liability company under the laws of
Bermuda. All actions necessary to authorize SNSL to enter into, deliver and
carry out its obligations under the Transaction Documents have been taken.
Neither the execution and delivery of the Transaction Documents nor the
consummation of the transactions contemplated thereby will result in a violation
of or a conflict with the certificate of formation, operating agreement or other
organizational document of SNSL.

            4.4 Organization of Acquired Companies; Authority; No Conflict or
Violation. Each Acquired Company is duly incorporated, validly existing and in
good standing under the laws of its jurisdiction of formation and has full
corporate power and authority to own its assets and properties and to enter
into, deliver and carry out its obligations under the Transaction Documents to
which it is a party. Each of the Transaction Documents to which each Acquired
Company is a party has been duly authorized, executed and delivered by or on
behalf of such Acquired Company. Each Transaction Document to which each
Acquired Company is a party is the legal, valid and binding obligation of such
Acquired Company, enforceable against such Acquired Company in accordance with
its terms except as such enforcement may be limited by bankruptcy, insolvency,
fraudulent conveyance, reorganization, moratorium and similar laws affecting the
enforceability of contractual obligations and creditor's rights generally and by
the application of equitable principles by courts of competent jurisdiction
sitting at law or in equity. Neither the execution and delivery of the
Transaction Documents nor the consummation of the transactions contemplated
thereby will conflict with the articles of incorporation or by-laws of either
Acquired Company or any contract to which an Acquired Company is a party or by
which any assets of an Acquired Company are bound, or will result in the
violation by any Acquired Company of any Legal Requirements. Each Acquired
Company has obtained all qualifications to do business necessary or required
under any applicable Legal Requirement as a result of the conduct of its
business or the ownership of its assets or properties. The corporate minute
books, registers and other corporate books and records of each Acquired Company
are each correct, current, and complete in all material respects, nothing has
been removed from such books and records, and the signatures appearing on all
documents


                                       -8-

contained therein are the true signatures of the Persons purporting to have
signed the same. All actions reflected in such books and records were duly and
validly taken in compliance with all applicable Legal Requirements. Except as
disclosed on Schedule 4.4 hereto, no Acquired Company owns any Equity Interests
of, nor is it in any manner affiliated (whether through an Investment or other
participation of any kind) with any Person.

            4.5 Capitalization of the Acquired Companies. The authorized capital
of each Acquired Company is set forth on Schedule 4.5 hereto. All of the issued
and outstanding shares of capital stock of Cribewell are owned of record and
beneficially by NSMM free and clear of all Encumbrances. All of the issued and
outstanding shares of capital stock of each Acquired Company have been duly
authorized and are validly issued, fully paid and non-assessable. There are no
subscriptions, options, warrants, calls, commitments or other rights of any kind
outstanding for the purchase of, nor any securities convertible or exchangeable
for shares of an Acquired Company capital stock or other Equity Interests of any
Acquired Company.

            4.6 Authorization; Binding Effect. Each Acquired Company has all
necessary corporate power and authority to own, lease and operate the assets
owned by it and to conduct the business presently conducted by it.

            9.7 Delivery of SNSL Disclosure Schedules. SNSL shall have delivered
to WPS Ltd all SNSL Disclosure Schedules required in connection with the
representations and warranties of SNSL set forth in Article 4 of this Agreement,
and WPS Ltd shall, upon the review thereof, determine that all matters
disclosed thereon are satisfactory to WPS Ltd.

                                   ARTICLE 10

                                 INDEMNIFICATION

            10.1 Survival of Representations, etc. All statements contained in
the SNSL Disclosure Schedules or in any other schedule, certificate or
instrument or conveyance delivered by or on behalf of the parties pursuant to
this Agreement or in connection with the transactions contemplated hereby shall
be deemed to be representations and warranties by the parties hereunder. The
representations and warranties of WPS Ltd. and SNSL contained herein or in any
instrument delivered pursuant to this Agreement shall, without regard to any
investigation made by any of the parties hereto, survive the Closing Date for
the shorter of: (i) the period of any applicable statute of limitations (after
giving effect to any extensions or waivers thereof) or (ii) the period ending on
the fourth anniversary of the Closing Date. Anything to the contrary contained
in this Agreement notwithstanding, the termination or expiration of any
representation or warranty or indemnification obligation under this Article 9
shall not affect any claims made in writing by any Indemnified Party (as defined
below) hereunder prior to such expiration or termination. All covenants and
agreements of the parties contained in this Agreement shall survive the Closing
Date.

            10.2 Indemnification.

            (a) In addition to any other right or remedy available to WPS Ltd.
      at law or in equity, SNSL shall indemnify WPS Ltd. and its Affiliates, and
      their Representatives and permitted successors and assigns (collectively,
      the "WPS Ltd. Indemnities") against, and hold each WPS Ltd. Indemnitee
      harmless from, any diminution in value, demand, damage, claim, action,
      cause of action, deficiency, fine, liability, Tax or other loss or expense
      including, without limitation, interest, penalties and attorneys' fees and
      expenses (collectively, "Damages") arising out of or resulting from any
      inaccuracy, misrepresentation or breach of any representations or
      warranties made by SNSL contained in any Transaction Document or the
      nonfulfillment of any covenant or agreement of SNSL contained in any
      Transaction Document.

            (b) In addition to any other right or remedy available to SNSL at
      law or in equity, WPS Ltd. shall indemnify SNSL and its Affiliates, and
      their Representatives and permitted successors and assigns (collectively,
      the "SNSL Indemnities") against, and hold each SNSL Indemnity harmless
      from any Damages arising out of or resulting from any inaccuracy,
      misrepresentation or breach of any representations or warranties made by
      WPS Ltd. contained in any Transaction Documents or the


                                     - 21 -
<PAGE>   22

      nonfulfillment of any covenant or agreement of WPS Ltd. contained in any
      Transaction Document.

            The term "Damages" as used in this Section 9.2 is not limited to
matters asserted by any Persons against WPS Ltd. or SNSL, but includes Damages
incurred or sustained by in the absence of claims by other Persons.

            10.3 Indemnification Procedures.

            (a) Notice of Claim. Any Person making a claim for indemnification
      pursuant to Section 9.2 (an "Indemnified Party") must give any party
      hereto from whom indemnification is sought (an "Indemnifying Party")
      written notice of such claim (an "Indemnification Claim Notice") promptly
      after the Indemnified Party receives any written notice of any action,
      lawsuit, proceeding, investigation or other claim or potential claim (a
      "Proceeding") against or involving the Indemnified Party by any government
      entity or other Person or otherwise discovers or becomes aware of the
      liability, obligation or facts giving rise to such claim for
      indemnification; provided that the failure to notify or delay in notifying
      an Indemnifying Party will not relieve any Indemnifying Party of its
      obligations pursuant to Section 9.2.

            (b) Control of Defense. With respect to the defense of any
      Proceeding against or involving an Indemnified Party in which a
      governmental entity or other Person in question seeks only the recovery of
      a sum of money for which indemnification is provided, at its option an
      Indemnifying Party may appoint as lead counsel of such defense any legal
      counsel selected by the Indemnifying Party; provided that before the
      Indemnifying Party assumes control of such defense it must first:

                  (i) enter into an agreement with the Indemnified Party (in
      form and substance satisfactory to the Indemnified Party) pursuant to
      which the Indemnifying Party agrees to be fully responsible (with no
      reservation of any rights other than the right to be subrogated to the
      rights of the Indemnified Party) for all Damages relating to such
      Proceeding and unconditionally guarantees the payment and performance of
      any liability or obligation which may arise with respect to such
      Proceeding or the facts giving rise to such claim for indemnification; and

                  (ii) furnish the Indemnified Party with reasonable assurance
      that the Indemnifying Party has the financial capacity to defend such
      Proceeding and to satisfy any such liability.

            (c) Control of Defense; Exceptions, etc. The Indemnified Party will
      be entitled to participate in the defense of such claim and to employ
      counsel of its choice for such purpose at its own expense (provided that
      the Indemnifying Party will bear the reasonable fees and expenses of such
      separate counsel incurred prior to the date


                                     - 22 -
<PAGE>   23

      upon which the Indemnifying Party effectively assumes control of such
      defense). The Indemnifying Party will not be entitled to assume control of
      the defense of such claim, and will pay the fees and expenses of legal
      counsel retained by the Indemnified Party, if:

                  (i) the Indemnified Party reasonably believes that an adverse
      determination of such Proceeding could be detrimental to or injure the
      Indemnified Party's reputation or future business prospects,

                  (ii) the Indemnified Party reasonably believes that there
      exists or could arise a conflict of interest which, under applicable
      principles of legal ethics, could prohibit a single legal counsel from
      representing both the Indemnifying Party and the Indemnifying Party in
      such Proceeding, or

                  (iii) the Indemnifying Party has failed or is failing to
      prosecute or defend vigorously such claim.

            (d) Settlement of Claims. The Indemnifying Party must obtain the
      prior written consent of the Indemnified Party (which the Indemnified
      Party will not unreasonably withhold) prior to entering into any
      settlement of such Proceeding or ceasing to defend such Proceeding.

            10.4 No Right of Contribution. After the Closing, no Acquired
Company shall have any liability to indemnify SNSL on account of a
misrepresentation or the breach of any representation or warranty or the
nonfulfillment of any covenant or agreement of SNSL; and SNSL shall not have any
right to seek contribution against any Acquired Company.

                                   ARTICLE 11

                                  MISCELLANEOUS

            11.1 Termination. This Agreement may be terminated at any time prior
to the Closing:

            (a) by written agreement of WPS Ltd. and SNSL;

            (b) by WPS Ltd., if SNSL or any Acquired Company is in breach of any
      of its respective obligations pursuant to the Transaction Documents or if
      any representation or warranty of either SNSL or any Acquired Company
      contained therein is false or misleading in any material respect (provided
      that such condition is not the result of any breach of any covenant,
      representation or warranty of WPS Ltd. set forth in any Transaction
      Document); or


                                     - 23 -
<PAGE>   24

            (c) by SNSL, if WPS Ltd. is in breach of its obligations pursuant to
      the Transaction Documents or if any representation or warranty of WPS Ltd.
      contained therein is false or misleading in any material respect (provided
      that such condition is not the result of any breach of any covenant,
      representation or warranty of SNSL set forth in this Agreement or in any
      of the other Transaction Documents).

            Any termination of this Agreement pursuant to clause (b) or (c) will
be effected by written notice from the terminating party to the other party. Any
termination of this Agreement pursuant to clause (b) or (c) will not terminate
the liability of any party hereto for any willful failure of any party to have
performed any of its obligations hereunder or for any knowing misrepresentation
made by any party of any matter set forth in this Agreement or any other
Transaction Document which exists at the time of such termination.

            11.2 Assignment. Neither this Agreement nor any of the rights or
obligations hereunder may be assigned by any party without the prior written
consent of the other party; provided, however, that SNSL may assign its right to
receive WPS Ltd. Exchange Shares hereunder to any Permitted SNSL Assignee if
such Permitted SNSL Assignee has executed and delivered to WPS Ltd. a written
undertaking by which it agrees to be bound by the terms of the Stock Call
Agreement and the indemnification provisions of this agreement and provided
further that WPS Ltd. may assign its right to receive NSMM Outstanding Shares
hereunder to any Permitted WPS Ltd. Assignee. Subject to the foregoing, this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns, and no other Person shall have any
right, benefit or obligation hereunder.

            11.3 Notices. Unless otherwise provided herein, any notice, request,
instruction or other document to be given hereunder by any party to the others
shall be in writing and delivered in person or by courier or by facsimile
transmission or mailed by certified mail, postage prepaid, return receipt

other Person to whom a copy of such communication is to be delivered pursuant to
this Section 10.3).

            11.4 Choice of Law; Venue. This Agreement shall be construed and
interpreted and the rights of the parties hereto shall be determined in
accordance with the laws of Bermuda, without giving effect to any choice of law
or conflict provision or rule (whether of Bermuda or any other jurisdiction)
that would cause the laws of any jurisdiction other than Bermuda to be applied.
In furtherance of the foregoing, the internal law of the Islands of Bermuda will
control the interpretation and construction of this Agreement, even if under
such jurisdiction's choice of law or conflict of law analysis, the substantive
law of some other jurisdiction would ordinarily apply. Each party agrees that
any legal action or proceeding relating to this Agreement may be brought in any
appropriate court in Bermuda and waives any objection that it may now or
hereafter have to such venue for any such action.

            11.5 Entire Agreement; Amendments and Waivers. This Agreement,
together with all exhibits and schedules hereto (which form a part of this
Agreement and are incorporated into this Agreement for all purposes),
constitutes the entire agreement among the parties hereto pertaining to the
subject matter hereof and supersedes all prior agreements, understandings,
negotiations and discussions, whether oral or written, of the parties. No
supplement, modification or waiver of this Agreement shall be binding unless
executed in writing by the party to be bound thereby. No waiver of any of the
provisions of this Agreement shall be deemed or shall constitute a waiver of any
other provision hereof (whether or not similar), nor shall such waiver
constitute a continuing waiver unless otherwise expressly provided.

            11.6 Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

            11.7 Invalidity. In the event that any one or more of the provisions
contained in this Agreement or in any other instrument referred to herein,
shall, for any reason, be held to be invalid, illegal or unenforceable in any
respect, such invalidity, illegality or unenforceability shall not affect any
other provision of this Agreement or any other such instrument.

            11.8 Headings. The headings of the Articles and Sections herein are
inserted for convenience of reference only and are not intended to be a part of
or to affect the meaning or interpretation of this Agreement.

            11.9 Singulars and Plurals. All references to the plural herein
shall also mean the singular and to the singular shall also mean the plural, in
each case, as applicable.

            11.10 Expenses. Except as otherwise provided herein, SNSL shall be
responsible for SNSL Expenses, and WPS Ltd. shall be responsible for WPS Ltd.
Expenses.

            11.11 Publicity. Unless required to do so by applicable law or legal
process, no party hereto shall issue any press release or make any public
statement regarding the Transaction Documents or the transactions contemplated
thereby without the prior written approval of the other parties (which approval
may not be unreasonably withheld or delayed). If any party hereto is required by
law or legal process to make any public statement regarding the Transaction
Documents or the transactions contemplated thereby, such party must first
provide to the other parties the content of the proposed public statement, the
reasons that such disclosure is required by law or legal process, and the time
and place that the public statement will be made, in each case to the extent
permitted by law or legal process and to the extent reasonably practicable.

            11.12 Remedies. No failure to exercise, and no delay in exercising,
any right, remedy, power or privilege under this Agreement by any party hereto
will operate as a waiver of such right, remedy, power or privilege, nor will any
single or partial exercise of any right, remedy, power or privilege under this
Agreement preclude any other or further exercise of such right, remedy, power or
privilege or the exercise of any other right, remedy, power or privilege. The
rights, remedies, powers and privileges provided pursuant to this Agreement are
cumulative and not exhaustive of any other rights, remedies, powers and
privileges which may be provided by law.

            11.13 Confidential Information. The parties hereto acknowledge that
the transactions contemplated by this Agreement are of a confidential nature.
Each party hereto further acknowledges that, in connection with the negotiation
of the Transaction Documents and the preparation for the consummation of the
transactions contemplated thereby, it will have access to confidential
information relating to the other parties. The parties hereto agree that they
will treat as confidential, will not duplicate (except to their respective
Representatives in connection with the transactions contemplated by the
Transaction Documents) or use, and will maintain the confidentiality of (and
will use their respective best efforts to cause and be responsible for the
Representatives of such party to maintain the confidentiality of), any written,
oral, or other information obtained from the other parties in connection with
the Transaction Documents or the transactions contemplated thereby, unless (a)
such information is already known to such party or to others not bound by a duty
of confidentiality or such information becomes publicly available through no
fault of such party, (b) the use of such information is necessary or appropriate
in making any filing or obtaining any consent or approval required for the
consummation of the transactions contemplated by the Transaction Documents, or
(c) the furnishing or use of such information is required by applicable law or
legal process. In the event of the termination of this Agreement for any reason
whatsoever, each party hereto shall destroy or return to the other all parties
documents, work papers and other material (including all copies thereof)
obtained in connection with the transactions contemplated by the Transaction
Documents and will keep confidential (and will so instruct and be responsible
for its Representatives and others who


                                     - 27 -
<PAGE>   28

have had access to confidential information) and will not use any such
information, unless such information is now, or is hereafter, disclosed through
no act or omission of such party, in any manner making it available to the
general public.

            11.14 Effective Date. The parties agree that notwithstanding the
actual Closing Date, the transactions contemplated by the Transaction Documents
shall be deemed to have been consummated on the Effective Date.

            11.15 Further Assurances. On and after the Closing Date, each party
will take all appropriate action and execute all documents, instruments or
conveyances of any kind which may be reasonably necessary or advisable to carry
out any of the provisions hereof.

            IN WITNESS WHEREOF, the parties hereto have executed this Agreement,
or have caused this Agreement to be duly executed on their behalf by their
respective officers thereunto duly authorized, as of the day and year first
above written.
