ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Delaware General Corporation Law (the "DGCL") permits a Delaware
corporation to include in its charter and bylaws certain provisions to eliminate
the personal liability of directors for monetary damages and to indemnify its
directors and officers. The MIIX Group By-laws (the "By-laws") provide that
subject to certain exceptions in the case of actions by or in the right of The
MIIX Group, The MIIX Group shall indemnify its directors and officers, and may
indemnify its agents and employees, against judgments, fines and amounts paid in
settlement actually and reasonably incurred by him or her, incurred by reason of
the fact that such person was serving as a director, officer, employee or agent
of The MIIX Group, so long as such person acted and in a manner reasonably
believed to be in or not opposed to the best interest of The MIIX Group, and,
with respect to any criminal action, so long as the indemnified party had no
reason to believe that his or her conduct was unlawful. The MIIX Group's
Certificate of Incorporation provides that directors shall not be liable to The
MIIX Group or The MIIX Group's stockholders for monetary damages for breach of
his or her fiduciary duty as a director, except that liability may not be
eliminated (i) for any breach of such person's duty of loyalty, (ii) for acts or
omissions not in good faith or involving intentional misconduct or a knowing
violation of law, (iii) under Section 174 of the DGCL or (iv) for any
transaction in which such person received an improper personal benefit. Section
145(a) of the DGCL provides that a corporation may indemnify a director,
officer, employee, or agent if such person acted in good faith and in a manner
reasonably believed to be in, or not opposed to, the best interests of the
corporation and, with respect to any criminal proceeding, had no reasonable
cause to believe the conduct was unlawful. In addition, effective upon
consummation of the Reorganization, The MIIX Group will enter into
indemnification agreements with each of its directors and certain of its
executive officers that generally provide for similar indemnification. Insofar
as indemnification for liabilities arising under the Securities Act of 1933 may
be permitted to directors, officers or persons controlling the registrant
pursuant to the foregoing provisions, the Registrant has been informed that in
the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Act and is therefore unenforceable.

     The Underwriting Agreement provides for indemnification by the Underwriters
of the registrant and its directors, officers and controlling persons for
certain liabilities, including liabilities arising under the Securities Act of
1933, as amended.

ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES.

     The MIIX Group was incorporated under the laws of the State of Delaware on
October 14, 1997. On October 15, 1997, The MIIX Group issued 10 shares of its
Common Stock, par value $.01 per share, to the Medical Inter-Insurance Exchange
of New Jersey for an aggregate purchase price of $10. Such issuance was exempt
from registration under the Securities Act of 1933, as amended, pursuant to
Section 4(2) thereof, because such issuance did not involve any public offering
of securities.

     The required schedules as identified on the Index to Consolidated Financial
Statements on page F-1 of the Prospectus forming part of this Registration
Statement and are incorporated herein by reference. All other schedules for

ITEM 17.  UNDERTAKINGS.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.


     The undersigned registrant hereby undertakes that:



          (1) For purposes of determining the liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this registration statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     registration statement as of the time it was declared effective.



          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

Ladies and Gentlemen:

                  The MIIX Group, Incorporated, a corporation organized under
the laws of Delaware (the "Company"), proposes to sell to the several
underwriters named in Schedule I hereto (the "Underwriters"), for whom you (the
"Representatives") are acting as representatives, _________ shares of Common
Stock, $.01 par value ("Common Stock"), of the Company (said shares to be issued
and sold by the Company being hereinafter called the "Underwritten Securities").
The Company also proposes to grant to the Underwriters an option to purchase up
to _________ additional shares of Common Stock to cover over-allotments (the
"Option Securities"; the Option Securities, together with the Underwritten
Securities, being hereinafter called the "Securities"). To the extent there are
no additional Underwriters listed on Schedule I other than you, the term
Representatives as used herein shall mean you, as Underwriters, and the terms
Representatives and Underwriters shall mean either the singular or plural as the
context requires. Certain terms used herein are defined in Section 17 hereof.

                  The Company is a wholly owned subsidiary of the Medical
Inter-Insurance Exchange of New Jersey, a reciprocal insurer organized under the
laws of New Jersey (the "Exchange"), and MIIX Insurance Company, a stock
insurance company organized under the laws of New Jersey ("MIIX Insurance"), is
a wholly owned subsidiary of the Company. Each of the Company and MIIX Insurance
was formed in connection with a proposed reorganization (the "Reorganization")
of the Exchange pursuant to the Plan of Reorganization adopted by the Exchange's
Board of Governors on October 15, 1997 (the "Original Plan", and as amended to
the date hereof, the "Plan") and approved by order (the "Order") dated March 5,
1998 of the Commissioner of Insurance of the Department of Banking and Insurance
of the State of New Jersey (the "Commissioner"). As part of the Reorganization,
(i) the Exchange will distribute (the "Distribution") shares of Common Stock
(the "Reorganization Shares") or, in certain cases, cash

(a)  Plus an option to purchase from the Company, up to ______ additional shares
     of Common Stock to cover over-allotments.
<PAGE>   2
to Distributees (as defined in the Plan), (ii) the Company will purchase (the
"Purchase") for $100,000 in cash and [ ] shares of Common Stock all of the
outstanding shares of common stock of New Jersey State Medical Underwriters,
Inc., a corporation organized under the laws of New Jersey (the
"Attorney-in-Fact") and a wholly owned subsidiary of The Medical Society of the
State of New Jersey, a not-for-profit corporation organized under the laws of
New Jersey ("The Medical Society"), and (iii) the Exchange will transfer (the
"Transfer") all of its assets and liabilities (except for the Common Stock and
cash to be distributed pursuant to the Reorganization) to MIIX Insurance. Upon
effectiveness of the Plan (the "Plan Effective Time"), Membership Interests (as
defined in the Plan) will be extinguished and the Exchange will be dissolved.
The Purchase will be made pursuant to a Stock Purchase Agreement dated as of
October 15, 1997, as amended by Amendment No. 1 thereto dated as of September
20, 1998 and by Amendment No. 2 thereto dated as of December 21, 1998 (as so
amended, and together with the Waiver of Conditions and Notice of Certain
Matters thereto dated as of July [ ], 1999, the "Stock Purchase Agreement"),
between the Company and The Medical Society. The Transfer will be made pursuant
to an Assumption Reinsurance and Administration Agreement and an Assignment and
Assumption Agreement (together, the "Assumption Agreements") to be entered into
among the Company, the Exchange and MIIX Insurance.

                  The Company, the Exchange and MIIX Insurance are hereinafter
sometimes referred to collectively as the "MIIX Entities". The Attorney-in-Fact
and its subsidiaries, Lawrenceville Holdings, Inc., a corporation organized
under the laws of Delaware ("Lawrenceville Holdings"), and its subsidiaries, and
MIIX Insurance are hereinafter sometimes referred to collectively as the "MIIX
Subsidiaries". Lawrenceville Holdings, Lawrenceville Property and Casualty Co.,
Inc., a corporation organized under the laws of Virginia ("LP&C"), Lawrenceville
Re, Ltd., a corporation organized under the laws of Bermuda, MIIX Insurance and
MIIX Insurance Company of New York, a corporation organized under the laws of
New York ("MIIX New York"), are hereinafter sometimes referred to collectively
as the "Insurance Subsidiaries".

                  As part of the offering contemplated by this Agreement, First
Union Capital Markets Corp. ("First Union") has agreed to reserve out of the
Underwritten Securities set forth opposite its name on Schedule I to this
Agreement, up to 90,000 Underwritten Securities, for sale to the Company's and
the MIIX Subsidiaries' employees or officers (collectively, "Participants"), as
set forth in the Prospectus under the heading "Underwriting" (the "Directed
Share Program"). The Underwritten Securities to be sold by First Union pursuant
to the Directed Share Program (the "Directed Shares") will be sold by First
Union pursuant to this Agreement at the Offering Price (as defined in the
Prospectus). Any Directed Shares not orally confirmed for purchase by any
Participants by the end of the business day following the day on which this
Agreement is executed will be offered to the public by First Union as set forth
in the Prospectus.


                  1. Representations and Warranties. Each of the MIIX Entities,
jointly and severally, represents and warrants to, and agrees with, each
Underwriter as set forth below in this Section 1.

          (a) The Company has prepared and filed with the Commission a
     registration statement (file number 333-59371) on Form S-1, including a

     prospectus, for registration under the Act of the offering and sale of the
     Reorganization Shares. Such registration statement has become effective and
     no stop order suspending the effectiveness of such registration statement
     has been issued and no proceedings for that purpose have been instituted or
     threatened.

          (b) On the Distribution Effective Date and the Special Meeting Date
     (each as defined herein), the Distribution Registration Statement did not
     contain any untrue statement of a material fact or omit to state any
     material fact required to be stated therein or necessary in order to make
     the statements therein not misleading; and on the Distribution Effective
     Date and the Special Meeting Date, the Distribution Prospectus did not
     include any untrue statement of a material fact or omit to state a material
     fact necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading.

          (c) The Company has prepared and filed with the Commission a
     registration statement (file number 333-64707) on Form S-1, including a
     related preliminary prospectus, for registration under the Act of the
     offering and sale of the Securities. The Company may have filed one or more
     amendments thereto, including a related preliminary prospectus, each of
     which has previously been furnished to you. The Company will next file with
     the Commission either (1) prior to the Effective Date of such registration
     statement, a further amendment to such registration statement (including
     the form of final prospectus) or (2) after the Effective Date of such
     registration statement, a final prospectus in accordance with Rules 430A
     and 424(b). In the case of clause (2), the Company has included in such
     registration statement, as amended at the Effective Date, all information
     (other than Rule 430A Information) required by the Act and the rules
     thereunder to be included in such registration statement and the
     Prospectus. As filed, such amendment and form of final prospectus, or such
     final prospectus, shall contain all Rule 430A Information, together with
     all other such required information, and, except to the extent the
     Representatives shall agree in writing to a modification, shall be in all
     substantive respects in the form furnished to you prior to the Execution
     Time or, to the extent not completed at the Execution Time, shall contain
     only such specific additional information and other changes (beyond that
     contained in the latest Preliminary Prospectus) as the Company has advised
     you, prior to the Execution Time, will be included or made therein.

     (d) On the Effective Date, the Registration Statement did or will, and when
     the Prospectus is first filed (if required) in accordance with Rule 424(b)
     and on the Closing Date (as defined herein) and on any date on which Option
     Securities are purchased, if such date is not the Closing Date (a
     "settlement date"), the Prospectus (and any supplements thereto) will,
     comply in all material respects with the applicable requirements of the Act
     and the rules thereunder; on the Effective Date and at the Execution Time,
     the Registration Statement did not or will not contain any untrue statement
     of a material fact or omit to state any material fact required to be stated
     therein or necessary in order to make the statements therein not
     misleading; and, on the Effective Date, the Prospectus, if not filed
     pursuant to Rule 424(b), will not, and on the date of any filing pursuant
     to Rule 424(b) and on the Closing Date and any settlement date, the
     Prospectus (together with any supplement thereto) will not, include any
     untrue statement



                                       3
<PAGE>   4
     of a material fact or omit to state a material fact necessary in order to
     make the statements therein, in the light of the circumstances under which
     they were made, not misleading; provided, however, that the Company makes
     no representations or warranties as to the information contained in or
     omitted from the Registration Statement, or the Prospectus (or any
     supplement thereto) in reliance upon and in conformity with information
     furnished in writing to the Company by or on behalf of any Underwriter
     through the Representatives specifically for inclusion in the Registration
     Statement or the Prospectus (or any supplement thereto).

          (e) As of the date hereof, and until immediately prior to the Plan
     Effective Time, MIIX Insurance is, and will be, the only subsidiary of the
     Company. Immediately after the Plan Effective Time, the MIIX Subsidiaries
     will be the only direct and indirect subsidiaries of the Company and the
     Insurance Subsidiaries will be the only subsidiaries of the Company which
     accept insurance risk.

          (f) Each of the Company and the MIIX Subsidiaries has been duly
     incorporated and is validly existing as a corporation in good standing
     under the laws of the jurisdiction in which it is chartered or organized
     with full corporate power and authority to own or lease, as the case may
     be, and to operate its properties and conduct its business as described in
     the Prospectus, and is duly qualified to do business as a foreign
     corporation and is in good standing under the laws of each jurisdiction
     which requires such qualification wherein it owns or leases material
     properties and conducts material business and where the failure to be so
     qualified would, individually or in the aggregate, have a material adverse
     effect on the condition (financial or otherwise), prospects, earnings,
     business or properties of the Company, the Exchange and the MIIX
     Subsidiaries, taken as a whole, whether or not arising from transactions in
     the ordinary course of business (each such effect is hereinafter referred
     to as a "Material Adverse Effect").

          (g) The Exchange is a reciprocal insurance exchange duly organized
     under the laws of the State of New Jersey and is in compliance in all
     material respects with the requirements of the insurance laws of the State
     of New Jersey and the rules and regulations promulgated thereunder
     (collectively the "New Jersey Insurance Law") providing for the
     organization and regulation of reciprocal insurance exchanges; and has full
     power and authority to own or lease, as the case may be, and to operate its
     properties and conduct its business as described in the Prospectus, and is
     duly qualified to do business as a foreign corporation and is in good
     standing under the laws of each jurisdiction which requires such
     qualification wherein it owns or leases material properties and conducts
     material business and where the failure to be so qualified would,
     individually or in the aggregate, have a Material Adverse Effect.

          (h) All the outstanding shares of capital stock of each MIIX
     Subsidiary have been duly and validly authorized and issued and are fully
     paid and nonassessable, and, immediately after the Plan Effective Time, all
     outstanding shares of capital stock of the MIIX Subsidiaries will be owned
     by the Company either directly or through MIIX Subsidiaries free and clear
     of any perfected security interest or any other security interests, claims,
     liens or encumbrances, except that the shares of common stock of


                                       4
<PAGE>   5
     Lawrenceville Re, Ltd. and Pegasus Advisors, Inc. owned by the
     Attorney-in-Fact have been pledged to Underwriters Reinsurance Company
     pursuant to the Demand Loan dated January 23, 1997.

          (i) The Company's authorized equity capitalization is as set forth in
     the Prospectus; the capital stock of the Company conforms in all material
     respects to the description thereof contained in the Prospectus; the
     outstanding shares of Common Stock have been duly and validly authorized
     and issued and are fully paid and nonassessable; the Securities have been
     duly and validly authorized, and, when issued and delivered to and paid for
     by the Underwriters pursuant to this Agreement, will be fully paid and
     nonassessable; the Reorganization Shares have been duly and validly
     authorized, and, when issued and delivered to Members (as defined in the
     Plan) in exchange for their Membership Interests and to Look-Back Insureds
     (as defined in the Plan), in each case as provided in the Plan, will be
     fully paid and nonassessable, no holder thereof will be subject to personal
     liability by reason of being such a holder and all corporate action
     required to be taken for the authorization and issuance of the
     Reorganization Shares has been validly and sufficiently taken; the
     Securities and the Reorganization Shares are duly listed, and admitted and
     authorized for trading, subject to official notice of issuance and evidence
     of satisfactory distribution, on the New York Stock Exchange; the
     certificates for the Securities and the Reorganization Shares are in valid
     and sufficient form; neither the holders of outstanding shares of capital
     stock of the Company, the Distributees nor the other policyholders of the
     Exchange are entitled to preemptive or other rights to subscribe for the
     Securities or the Reorganization Shares; and, except as set forth in the
     Prospectus, no options, warrants or other rights to purchase, agreements or
     other obligations to issue, or rights to convert any obligations into or
     exchange any securities for, shares of capital stock of or ownership
     interests in the Company or any MIIX Subsidiary are outstanding.

          (j) There is no franchise, contract or other document of a character
     required to be described in the Registration Statement or Prospectus, or to
     be filed as an exhibit thereto, which is not described or filed as
     required; and the statements in the Prospectus under the headings
     "Prospectus Summary -- The Reorganization and Distribution", "-- Regulatory
     Approvals", "Risk Factors -- Actions Opposing the Plan of Reorganization",
     "-- Regulatory and Related Matters", "-- State Insurance Regulatory
     Approvals", "The Reorganization", "Business -- Regulation",
     "-- Litigation", "Management -- Executive Compensation", "-- Employment
     Agreements", "-- Deferred Compensation Agreements", "-- Stock Purchase and
     Loan Agreements", "-- Compensation Plans", "-- Certain Relationships and
     Related Transactions" and "Description of Capital Stock" fairly summarize
     the matters therein described.

          (k) This Agreement has been duly authorized, executed and delivered by
     each MIIX Entity. Each of the Assumption Agreements and the Stock Purchase
     Agreement has been duly authorized, executed and delivered by each MIIX
     Entity that is a party thereto and constitutes a valid and binding
     obligation of each such MIIX Entity enforceable in accordance with its
     terms, except as such enforceability may be limited by bankruptcy,
     insolvency, moratorium or similar laws now or hereafter in effect relating
     to creditors' rights generally, and by general principles of equity
     (regardless of whether


                                       5
<PAGE>   6
     enforceability is considered in a proceeding at law or in equity). The Plan
     has been duly authorized and executed by the Exchange.

          (l) Neither the Company nor any of the MIIX Subsidiaries is and, after
     giving effect to the offering and sale of the Securities and/or the
     Reorganization Shares and the application of the proceeds thereof as
     described in the Prospectus, will be an "investment company" or an entity
     "controlled" by an "investment company", as such terms are defined in the
     Investment Company Act of 1940, as amended.

          (m) No consent, approval, authorization, filing with or order of any
     court or governmental agency or body is required in connection with the
     transactions contemplated herein, except such as have been obtained and are
     in full force and effect under the Act and such as may be required under
     the blue sky laws of any jurisdiction in connection with the purchase and
     distribution of the Securities by the Underwriters in the manner
     contemplated herein and in the Prospectus; and no consent, approval,
     authorization, filing with or order of any court or governmental agency or
     body is required for the consummation of the transactions contemplated by
     the Plan, except such as have been obtained and are in full force and
     effect under the Act, the New Jersey Insurance Law, the New Jersey Business
     Corporation Act (the "New Jersey Corporations Law"), and the blue sky laws
     and insurance securities laws of various jurisdictions in connection with
     the issuance of the Reorganization Shares to the Distributees.

          (n) Neither the issue and sale of the Securities or the Reorganization
     Shares nor the consummation of any other of the transactions contemplated
     herein or in the Plan nor the fulfillment of the terms hereof or thereof
     will conflict with, result in a breach or violation of or imposition of any
     lien, charge or encumbrance upon any property or assets of the Company, any
     MIIX Subsidiary or the Exchange pursuant to, (i) the charter, by-laws or
     any other organizational document of the Company, any MIIX Subsidiary or
     the Exchange, (ii) the terms of any indenture, contract, lease, mortgage,

     their property is subject, or (iii) any statute, law, rule, regulation,
     judgment, order or decree applicable to the Company, any MIIX Subsidiary or
     the Exchange of any court, regulatory body, administrative agency,
     governmental body, arbitrator or other authority having jurisdiction over
     the Company, any MIIX Subsidiary or the Exchange or any of their respective
     properties, which violation or default would, in the case of clause (ii)
     above, either individually or in the aggregate with all other violations
     and defaults referred to in this paragraph (n) (if any), have a Material
     Adverse Effect.

          (o) No person has rights to the registration of any securities of the
     Company (owned or to be owned by such person) under the Registration
     Statement.

     for the consummation of the transactions contemplated by the Plan or for
     the effectiveness of the Plan; prior to or contemporaneously with the
     Closing Date, each of the actions required to occur and conditions required
     to be satisfied at or prior to the Plan Effective Time pursuant to the New
     Jersey Insurance Law, the Order or the Plan will have occurred or been

     rights and properties of, MIIX Insurance, and all the rights of creditors
     and liens of the Exchange shall become the rights of creditors and liens of
     MIIX Insurance.

          (q) Neither the issue and sale of the Securities nor the consummation
     of any other of the transactions contemplated herein nor the fulfillment of
     the terms hereof or thereof will conflict with or result in a violation of
     the Order or the Plan.

          (r) The consolidated historical financial statements and schedules of
     the Exchange and its subsidiaries included in the Prospectus and the
     Registration Statement present fairly in all material respects the
     financial condition, results of operations and cash flows of the Exchange
     and its subsidiaries as of the dates and for the periods indicated, comply
     in all material respects as to form with the applicable accounting
     requirements of the Act and have been prepared in conformity with generally
     accepted accounting principles applied on a consistent basis throughout the
     periods involved (except as otherwise noted therein). The financial
     statement schedules, if any, included in the Registration Statement and the
     Prospectus present fairly the information required to be stated therein.
     The selected financial data set forth under the captions "Prospectus
     Summary -- Summary Financial and Operating Data" and "Selected Financial

     certain ratios and other statistical data filed as part of the Registration

     permitted by the National Association of Insurance Commissioners and by the
     Department of Banking and Insurance of the State of New Jersey, and such
     statutory accounting practices have been applied on a consistent basis
     throughout the periods involved, except as may otherwise be indicated
     therein or in the notes thereto; and (ii) present fairly in all material
     respects the statutory financial position of the Exchange as at the dates
     thereof, and the statutory basis results of operations of the Exchange for
     the periods covered thereby.

          (t) Since the respective dates as of which information is given in the
     Registration Statement and the Prospectus, except as otherwise stated
     therein: (i) there has been no material adverse change in the condition
     (financial or otherwise), prospects, earnings, business or properties of
     the Company, the Exchange and the MIIX Subsidiaries, taken as a whole,
     whether or not arising from transactions in the ordinary course of business

     Company, the Exchange or any MIIX Subsidiary (iii) neither the Company, the

     surplus or reserves (including any such change in the unpaid losses and
     loss adjustment expenses reserves or reserving practices) of the Exchange
     or any Insurance Subsidiary.

          (u) Except as disclosed in the Prospectus (exclusive of any supplement
     thereto), no action, suit or proceeding by or before any court or
     governmental agency, authority or body or any arbitrator involving the
     Company, the Exchange or any of the MIIX Subsidiaries or its or their
     property is pending or, to the best knowledge of each of the Company, the
     Exchange and the MIIX Subsidiaries, threatened that (i) could reasonably be
     expected to have a material adverse effect on the performance of this
     Agreement or the consummation of any of the transactions contemplated
     hereby, (ii) could reasonably be expected to have Material Adverse Effect,
     (iii) challenges the Plan, the Reorganization (including, without
     limitation, the Distribution, the Purchase or the Transfer) or the
     consummation of the transactions contemplated thereby or (iv) is of a
     character required to be disclosed in the Registration Statement.

          (v) Each of the Company, the Exchange and the MIIX Subsidiaries owns
     or leases, or upon completion of the Reorganization will own or lease, all
     such properties as are necessary to the conduct of its operations as
     presently conducted.

          (w) Neither the Company, the Exchange nor any MIIX Subsidiary is in
     violation of or default under, and no event has occurred that, with notice
     or lapse of time or both, would constitute a violation of or default under,
     (i) any provision of its charter, bylaws, or other organizational document,
     (ii) the terms of any indenture, contract, lease, mortgage, deed of trust,

     covenant or instrument to which it is a party or bound or to which its
     property is subject, or (iii) any statute, law, rule, regulation, judgment,
     order or decree of any


                                       8
<PAGE>   9
     court, regulatory body, administrative agency, governmental body,
     arbitrator or other authority having jurisdiction over the Company, the
     Exchange or such MIIX Subsidiary or any of their respective properties, as
     applicable, which violation or default would, in the case of clauses (ii)
     and (iii) above, either individually or in the aggregate with all other
     violations and defaults referred to in this paragraph (w) (if any), have a
     Material Adverse Effect.

          (x) Ernst & Young LLP, who have certified certain consolidated
     financial statements of the Exchange and its subsidiaries and delivered
     their report with respect to the audited consolidated financial statements
     and schedules included in the Prospectus, are independent public
     accountants with respect to each of the Company and the Exchange within the
     meaning of the Act and the applicable published rules and regulations
     thereunder.

          (y) There are no transfer taxes or other similar fees or charges under
     Federal law or the laws of any state, or any political subdivision thereof,
     required to be paid in connection with the execution and delivery of this
     Agreement or the issuance by the Company or sale by the Company of the
     Securities.

          (z) Each of the Company, the Exchange and the MIIX Subsidiaries has
     filed all foreign, federal, state and local tax returns that are required
     to be filed or has requested extensions thereof (except in any case in
     which the failure so to file would not have a Material Adverse Effect,
     except as set forth in or contemplated in the Prospectus (exclusive of any
     supplement thereto)) and has paid all taxes required to be paid by it and
     any other assessment, fine or penalty levied against it, to the extent that
     any of the foregoing is due and payable, except for any such assessment,
     fine or penalty that is currently being contested in good faith or as would
     not have a Material Adverse Effect, except as set forth in or contemplated
     in the Prospectus (exclusive of any supplement thereto).

          (aa) No labor problem or dispute with the employees of the Company,
     the Exchange or any MIIX Subsidiary, exists or is threatened or imminent,
     and none of the Company, the Exchange or the MIIX Subsidiaries is aware of
     any existing or imminent labor disturbance by the employees of any of the
     Company's, the Exchange's or any MIIX Subsidiary's principal suppliers,
     contractors or customers, that could have a Material Adverse Effect, except
     as set forth in or contemplated in the Prospectus (exclusive of any
     supplement thereto).

          (bb) No subsidiary of the Company is currently prohibited, directly or
     indirectly, from paying any dividends to the Company, from making any other
     distribution on such subsidiary's capital stock, from repaying to the
     Company any loans or advances to such subsidiary from the Company or from
     transferring any of such subsidiary's property or assets to the Company or
     any other subsidiary of the Company, except as described in or contemplated
     by the Prospectus and except that MIIX New York may not pay dividends until
     two years following the approval of the change in the ultimate parent
     company of MIIX New York, and immediately after the Plan Effective Time,
     none of the MIIX Subsidiaries will be prohibited, directly or indirectly,
     from


                                       9
<PAGE>   10
     paying any dividends to the Company, from making any other distribution on
     such MIIX Subsidiary's capital stock, from repaying to the Company any
     loans or advances to such MIIX Subsidiary from the Company or from
     transferring any of such MIIX Subsidiary's property or assets to the
     Company or any other subsidiary of the Company, except as described in or
     contemplated by the Prospectus. Neither the Company, the Exchange nor any
     MIIX Subsidiary has received any notice of, or otherwise has any knowledge
     of, the issuance of, or commencement of any proceeding for the issuance of,
     any order or decree of an insurance regulatory agency or body, which order
     or decree would impair, restrict or prohibit the payment of dividends by
     any MIIX Subsidiary to the Company or to any other MIIX Subsidiary.

          (cc) Except as disclosed in the Prospectus (exclusive of any
     supplement thereto), none of the Exchange or the Insurance Subsidiaries has
     made a material change in its insurance reserving practices since March 31,
     1999.

          (dd) Each of the Company, the Exchange and the MIIX Subsidiaries
     possesses all licenses, certificates, permits and other authorizations
     issued by the appropriate federal, state or foreign regulatory authorities
     necessary to conduct its business as currently conducted and to own or
     lease, as the case may be, and to operate its properties except to the
     extent that the failure to possess such licenses, certificates, permits and
     other authorizations, would not, individually or in the aggregate, have a
     Material Adverse Effect; and neither the Company, the Exchange nor any such
     MIIX Subsidiary has received any notice of any proceeding relating to the
     revocation or modification of any such license, certificate, permit or
     authorization which, individually or in the aggregate, if the subject of an
     unfavorable decision, ruling or finding, would have a Material Adverse
     Effect, except as set forth in or contemplated in the Prospectus (exclusive
     of any supplement thereto).

          (ee) Each of the Company, the Exchange and the Insurance Subsidiaries
     is duly organized and licensed as an insurance or insurance holding company
     in its respective jurisdiction of organization or incorporation, as the
     case may be, and none of the Company, the Exchange and the MIIX
     Subsidiaries has received any notification from any insurance regulatory
     authority to the effect that any additional authorization, approval, order,
     consent, license, certificate, permit, registration or qualification from
     such insurance regulatory authority is needed to be obtained; each of the
     Company, the Exchange and the Insurance Subsidiaries is duly licensed and
     authorized to conduct its insurance business under the insurance laws of
     each jurisdiction in which it conducts such business so as to require such
     licensing and authorization; all such licenses and authorizations are in
     full force and effect, the Company, the Exchange and each Insurance
     Subsidiary have fulfilled and performed all obligations necessary to
     maintain such licenses and authorizations, and there is no event or
     proceeding or, to the Company's knowledge, inquiry or investigation that
     could result in the suspension, revocation or limitation of any such
     licenses or authorizations or otherwise impose any limitation on the
     conduct of the business of the Company, the Exchange or any Insurance
     Subsidiary, and there is no sustainable basis for any such suspension,
     revocation or limitation; each of the Company, the Exchange and the
     Insurance Subsidiaries is in compliance with, and conducts its business in
     conformity with, all applicable insurance


                                       10
<PAGE>   11
     laws and regulations, except where the failure to comply or conform with
     such laws and regulations, would not, individually or in the aggregate,
     have a Material Adverse Effect; all pending significant examinations, and
     all significant examinations that have been completed since March 5, 1999
     by any governmental authority having jurisdiction to regulate the insurance
     operations of the Company, the Exchange or any Insurance Subsidiary are
     disclosed in the Prospectus. The Company, the Exchange and each Insurance
     Subsidiary have filed all reports, information statements and other
     documents with the insurance regulatory authorities of each jurisdiction
     which requires any such filing and as are required to be filed pursuant to
     the insurance statutes of such jurisdictions and the rules and regulations
     of the insurance regulatory authorities thereunder.

          (ff) All reinsurance treaties and arrangements to which the Exchange
     or any of the Insurance Subsidiaries is a party are in full force and
     effect and neither the Exchange nor any of the Insurance Subsidiaries is in
     violation of or in default in the performance, observance or fulfillment
     of, any material obligation, agreement, covenant or condition contained
     therein; upon the effectiveness of the Transfer, all such treaties and
     arrangements to which the Exchange is a party shall remain in full force
     and effect and inure to the benefit of, and be enforceable by, MIIX
     Insurance; neither the Company, the Exchange nor any of the Insurance
     Subsidiaries has received any notice from any of the other parties to such
     treaties or arrangements that such other party intends not to perform such
     treaty or arrangement, except as would not have a Material Adverse Effect
     and, each of the Company, the Exchange and the Insurance Subsidiaries, to
     its best knowledge, has no reason to believe that any of the other parties
     to such treaties or arrangements will be unable to perform any such
     treaties or arrangements, except as would not have a Material Adverse
     Effect.

          (gg) No change in any insurance laws, rules or regulations has been
     introduced in any legislative or regulatory forum in the State of New
     Jersey, Pennsylvania or Virginia, or, to the knowledge of each MIIX Entity,
     in any other state that if adopted, is likely to have, either individually
     or in the aggregate with all other changes referred to in this paragraph
     (gg) (if any), a Material Adverse Effect.

          (hh) The Exchange and LP&C are each rated "A" (Excellent) by A.M. Best
     & Company Inc. ("A.M. Best"). The MIIX Entities have had recent discussions
     with A.M. Best. Each MIIX Entity believes that the first rating issued by
     A.M. Best after the Plan Effective Time for each of MIIX Insurance and LP&C
     will be an "A" (Excellent) rating.

          (ii) Each of the Company, the Exchange and the MIIX Subsidiaries
     maintains a system of internal accounting controls sufficient to provide
     reasonable assurance that (i) transactions are executed in accordance with
     management's general or specific authorizations; (ii) transactions are
     recorded as necessary to permit preparation of financial statements in
     conformity with generally accepted accounting principles and to maintain
     asset accountability; (iii) access to assets is permitted only in
     accordance with management's general or specific authorization; and (iv)
     the recorded accountability for assets is compared with the existing assets
     at reasonable intervals and appropriate action


                                       11
<PAGE>   12
     is taken with respect to any differences. On and after the Plan Effective
     Time, each of the Company and the MIIX Subsidiaries will continue to
     maintain such a system.

          (jj) Neither the Company, the Exchange nor any MIIX Subsidiary has
     taken, directly or indirectly, any action designed to or which has
     constituted or which might reasonably be expected to cause or result, under
     the Exchange Act or otherwise, in stabilization or manipulation of the
     price of any security of the Company to facilitate the sale or resale of
     the Securities or the Reorganization Shares.

          (kk) Each of the Company, the Exchange and the MIIX Subsidiaries is
     (i) in compliance with any and all applicable foreign, federal, state and
     local laws and regulations relating to the protection of human health and
     safety, the environment or hazardous or toxic substances or wastes,
     pollutants or contaminants ("Environmental Laws"), (ii) has received and is
     in compliance with all permits, licenses or other approvals required of it
     under applicable Environmental Laws to conduct its business and (iii) has
     not received notice of any actual or potential liability for the
     investigation or remediation of any disposal or release of hazardous or
     toxic substances or wastes, pollutants or contaminants, except where such
     non-compliance with Environmental Laws, failure to receive required
     permits, licenses or other approvals, or liability would not, individually
     or in the aggregate, have a Material Adverse Effect, except as set forth in
     or contemplated in the Prospectus (exclusive of any supplement thereto).
     Neither the Company, the Exchange nor any MIIX Subsidiary has been named as
     a "potentially responsible party" under the Comprehensive Environmental
     Response, Compensation, and Liability Act of 1980, as amended.

          (ll) Each of the Company, the Exchange and the MIIX Subsidiaries has
     fulfilled its obligations, if any, under the minimum funding standards of
     Section 302 of the United States Employee Retirement Income Security Act of
     1974 ("ERISA") and the regulations and published interpretations thereunder
     with respect to each "plan" (as defined in Section 3(3) of ERISA and such
     regulations and published interpretations) in which employees of the
     Company, the Exchange or any MIIX Subsidiary are eligible to participate
     and each such plan is in compliance in all material respects with the
     presently applicable provisions of ERISA and such regulations and published
     interpretations. Neither the Company, the Exchange nor any MIIX Subsidiary
     has incurred any unpaid liability to the Pension Benefit Guaranty
     Corporation (other than for the payment of premiums in the ordinary course)
     or to any such plan under Title IV of ERISA.

          (mm) The subsidiaries listed on Annex A attached hereto are the only
     subsidiaries of the Exchange and the Attorney-in-Fact, respectively. MIIX
     Insurance is the only significant subsidiary of the Exchange, and will be
     the only significant subsidiary of the Company immediately after the Plan
     Effective Time, as defined by Rule 1-02 of Regulation S-X. For purposes of
     this Agreement, the term "Significant Subsidiary" shall mean each of MIIX
     Insurance and LP&C.

          (nn) Each of the Company, the Exchange and the MIIX Subsidiaries owns,
     possesses, licenses or has other rights to use, on reasonable terms, all
     patents, patent applications, trade and service marks, trade and service
     mark registrations, trade names,


                                       12
<PAGE>   13
     copyrights, licenses, inventions, trade secrets, technology, know-how and
     other intellectual property (collectively, other than software generally
     available for public purchase, the "Intellectual Property") necessary for
     the conduct of its business as now conducted or as proposed in the
     Prospectus to be conducted. There are no rights of third parties to any
     such Intellectual Property, except for the rights of owners of Intellectual
     Property licensed by the Company, the Exchange or the MIIX Subsidiaries; to
     the Company's knowledge, there is no material infringement by third parties
     of any such Intellectual Property; there is no pending or, to the Company's
     knowledge, threatened action, suit, proceeding or claim by others
     challenging the Company's, the Exchange's or any MIIX Subsidiary's rights
     in or to any such Intellectual Property (including software generally
     available for public purchase), and each of the Company, the Exchange and
     the MIIX Subsidiaries is unaware of any facts which would form a reasonable
     basis for any such claim; there is no pending or, to the Company's
     knowledge, threatened action, suit, proceeding or claim by others
     challenging the validity or scope of any such Intellectual Property, and
     each of the Company, the Exchange and the MIIX Subsidiaries is unaware of
     any facts which would form a reasonable basis for any such claim; there is
     no pending or, to the Company's knowledge, threatened action, suit,
     proceeding or claim by others that the Company, the Exchange or any MIIX
     Subsidiary infringes or otherwise violates any patent, trademark,
     copyright, trade secret or other proprietary rights of others, and each of
     the Company, the Exchange and the MIIX Subsidiaries is unaware of any other
     fact which would form a reasonable basis for any such claim; there is no
     U.S. patent or, to the Company's knowledge, published U.S. patent
     application which contains claims that dominate or may dominate any
     Intellectual Property described in the Prospectus as being owned by or
     licensed to the Company, the Exchange or any MIIX Subsidiary or that
     interferes with the issued or pending claims of any such Intellectual
     Property; and there is no prior art of which the Company, the Exchange or
     any MIIX Subsidiary is aware that may render any U.S. patent held by the
     Company invalid or any U.S. patent application held by the Company, the
     Exchange or any MIIX Subsidiary unpatentable which has not been disclosed
     to the U.S. Patent and Trademark Office. Immediately after the Plan
     Effective Time, all of the Exchange's rights in respect of such
     Intellectual Property shall inure to the benefit of, and be enforceable by,
     MIIX Insurance.

          (oo) Except as disclosed in the Registration Statement and the
     Prospectus, neither the Company, the Exchange nor any MIIX Subsidiary (i)
     has any material lending or other relationship with any bank or lending
     affiliate of First Union Capital Markets Corp., Friedman, Billings, Ramsey
     & Co., Inc. or Hoefer & Arnett Incorporated and (ii) intends to use any of
     the proceeds from the sale of the Securities hereunder to repay any
     outstanding debt owed to any affiliate of First Union Capital Markets
     Corp., Friedman, Billings, Ramsey & Co., Inc. or Hoefer & Arnett
     Incorporated.

          (pp) The Company, the Exchange and the MIIX Subsidiaries have
     implemented a program to analyze and address the risk that the computer
     hardware and software used by each of them may be unable to recognize and
     properly execute date-sensitive functions involving certain dates prior to
     and any dates after December 31, 1999 (the "Year 2000 Problem"), and have
     determined that such risk will not have a Material Adverse Effect; and the
     Company, the Exchange and the MIIX Subsidiaries believe, after due inquiry,
     that each supplier, vendor, or financial service organization used or
     serviced


                                       13
<PAGE>   14
     by the Company, the Exchange or any MIIX Subsidiary has remedied or will
     remedy on a timely basis the Year 2000 Problem, except to the extent that a
     failure to remedy by any such supplier, vendor, or financial service
     organization would not, individually or in the aggregate with all such
     other failures, have a Material Adverse Effect.

          (qq) Except as disclosed in the Prospectus, there are no business
     relationships or related party transactions required to be disclosed
     therein by Item 404 of Regulation S-K of the Commission.

          (rr) MIIX Insurance has obtained regulatory approval to become an
     admitted carrier in the states of Connecticut, Delaware, Maryland,
     Michigan, New Jersey, Pennsylvania, Vermont and West Virginia and will, as
     of the Closing Date, have obtained regulatory approval to become an
     admitted carrier in the state of Kentucky. MIIX insurance has also obtained
     regulatory approval of its rates, rules and policy forms in each of those
     states. The state of Virginia has approved the change in LP&C's ultimate
     parent from the Exchange to the Company and the state of New York has
     approved the change in MIIX New York's ultimate parent from the Exchange to
     the Company. The appropriate regulatory bodies in the states of
     Connecticut, Delaware and West Virginia have approved the assignment to
     MIIX Insurance of all reinsurance agreements to which the Exchange is a
     party, and the reinsurers to such agreements have consented to such
     assignment.

                  Furthermore, each of the MIIX Entities, jointly and severally,
represents and warrants to First Union that it has not offered, or caused the
Underwriters to offer, Underwritten Securities to any person pursuant to the
Directed Share Program with the specific intent to unlawfully influence (x) a
customer or supplier of any of the MIIX Entities to alter the customer's or
supplier's level or type of business with such MIIX Entity, or (y) a trade
journalist or publication to write or publish favorable information about any
MIIX Entity or its products.

                  Any certificate signed by any officer of a MIIX Entity and
delivered to the Representatives or counsel for the Underwriters in connection
with the offering of the Securities shall be deemed a representation and
warranty by such MIIX Entity, as to matters covered thereby, to each
Underwriter.

                  2. Purchase and Sale. (a) Subject to the terms and conditions
and in reliance upon the representations and warranties herein set forth, the
Company agrees to sell to each Underwriter, and each Underwriter agrees,
severally and not jointly, to purchase from the Company, at a purchase price of
$   per share, the amount of the Underwritten Securities set forth opposite such
Underwriter's name in Schedule I hereto.

                  (b) Subject to the terms and conditions and in reliance upon
the representations and warranties herein set forth, the Company hereby grants
an option to the several Underwriters to purchase, severally and not jointly, up
to    Option Securities at the same purchase price per share as the Underwriters
shall pay for the Underwritten Securities. Said option may be exercised only to
cover over-allotments in the sale of the Underwritten Securities by the
Underwriters. Said option may be exercised in whole or in part at any time (but
not more than once) on or before the 30th day after the date of the Prospectus
upon written or telegraphic notice


                                       14
<PAGE>   15
by the Representatives to the Company setting forth the number of shares of the
Option Securities as to which the several Underwriters are exercising the option
and the settlement date. The number of Option Securities to be purchased by each
Underwriter shall be the same percentage of the total number of shares of the
Option Securities to be purchased by the several Underwriters as such
Underwriter is purchasing of the Underwritten Securities, subject to such
adjustments as you in your absolute discretion shall make to eliminate any
fractional shares.

                  3. Delivery and Payment. Delivery of and payment for the
Underwritten Securities and (if the option provided for in Section 2(b) hereof
shall have been exercised on or before the third Business Day prior to the
Closing Date) the Option Securities shall be made at 10:00 AM, New York City
time, on , 19 , or at such time on such later date not more than three Business
Days after the foregoing date as the Representatives shall designate, which date
and time may be postponed by agreement between the Representatives and the
Company or as provided in Section 9 hereof (such date and time of delivery and
payment for the Securities being herein called the "Closing Date"). Delivery of
the Securities shall be made to the Representatives for the respective accounts
of the several Underwriters against payment by the several Underwriters through
the Representatives of the purchase price thereof to or upon the order of the
Company by wire transfer payable in same-day funds to an account specified by
the Company. Delivery of the Underwritten Securities and the Option Securities
shall be made through the facilities of The Depository Trust Company unless the
Representatives shall otherwise instruct.

                  If the option provided for in Section 2(b) hereof is exercised
after the third Business Day prior to the Closing Date, the Company will deliver
the Option Securities (at the expense of the Company) to the Representatives, at
the offices of Cleary, Gottlieb, Steen & Hamilton, counsel for the Underwriters,
at One Liberty Plaza, New York, New York, on the date specified by the
Representatives (which shall be within two and five Business Days after exercise
of said option) for the respective accounts of the several Underwriters, against
payment by the several Underwriters through the Representatives of the purchase
price thereof to or upon the order of the Company by wire transfer payable in
same-day funds to an account specified by the Company. If settlement for the
Option Securities occurs after the Closing Date, the Company will deliver to the
Representatives on the settlement date for the Option Securities, and the
obligation of the Underwriters to purchase the Option Securities shall be
conditioned upon receipt of, supplemental opinions, certificates and letters
confirming as of such date the opinions, certificates and letters delivered on
the Closing Date pursuant to Section 6 hereof.

                  4. Offering by Underwriters. It is understood that the several
Underwriters propose to offer the Securities for sale to the public as set forth
in the Prospectus.

                  5. Agreements. Each of the MIIX Entities, jointly and
severally, agrees with the several Underwriters that:

                  (a) The Company will use its best efforts to cause the
         Registration Statement, if not effective at the Execution Time, and any
         amendment thereof, to become effective. Prior to the termination of the
         offering of the Securities, the Company will not file any amendment of
         the Registration Statement, any supplement to the Prospectus, or any
         Rule 462(b) Registration Statement unless the Company has furnished you
         a copy for


                                       15
<PAGE>   16
          your review prior to filing and will not file any such proposed
          amendment or supplement to which you reasonably object. Subject to the
          foregoing sentence, if the Registration Statement has become or
          becomes effective pursuant to Rule 430A, or filing of the Prospectus
          is otherwise required under Rule 424(b), the Company will cause the
          Prospectus, properly completed, and any supplement thereto to be filed
          with the Commission pursuant to the applicable paragraph of Rule
          424(b) within the time period prescribed and will provide evidence
          satisfactory to the Representatives of such timely filing. The Company
          will promptly advise the Representatives (1) when the Registration
          Statement, if not effective at the Execution Time, shall have become
          effective, (2) when the Prospectus, and any supplement thereto, shall
          have been filed (if required) with the Commission pursuant to Rule
          424(b) or when any Rule 462(b) Registration Statement shall have been
          filed with the Commission, (3) when, prior to termination of the
          offering of the Securities, any amendment to the Distribution
          Registration Statement or the Registration Statement shall have been
          filed or become effective, (4) of any request by the Commission or its
          staff for any amendment of the Distribution Registration Statement or
          the Registration Statement, or any Rule 462(b) Distribution
          Registration Statement or any Rule 462(b) Registration Statement, or
          for any supplement to the Distribution Prospectus or the Prospectus or
          for any additional information, (5) of the issuance by the Commission
          of any stop order suspending the effectiveness of the Distribution
          Registration Statement or the Registration Statement or the
          institution or threatening of any proceeding for that purpose and (6)
          of the receipt by the Company of any notification with respect to the
          suspension of the qualification of the Securities for sale, or of the
          Reorganization Shares for distribution, in any jurisdiction or the
          institution or threatening of any proceeding for such purpose. The
          Company will use its best efforts to prevent the issuance of any such
          stop order or the suspension of any such qualification and, if issued,
          to obtain as soon as possible the withdrawal thereof.

                  (b) If, at any time when a prospectus relating to the
         Securities is required to be delivered under the Act, any event occurs
         as a result of which the Prospectus as then supplemented would include
         any untrue statement of a material fact or omit to state any material
         fact necessary to make the statements therein in the light of the
         circumstances under which they were made not misleading, or if it shall
         be necessary to amend the Registration Statement or supplement the
         Prospectus to comply with the Act or the rules thereunder, the Company
         promptly will (1) notify the Representatives of any such event, (2)
         prepare and file with the Commission, subject to the second sentence of
         paragraph (a) of this Section 5, an amendment or supplement which will
         correct such statement or omission or effect such compliance, and (3)
         supply any supplemented Prospectus to you in such quantities as you may
         reasonably request.

                  (c) No later than 45 days following September 30, 2000, the
         Company will make generally available to its security holders and to
         the Representatives an earnings statement or statements of the Company
         and its subsidiaries which will satisfy the provisions of Section 11(a)
         of the Act and Rule 158 under the Act. The Company will file or cause
         to be filed with the Commission the information required by Rule 463
         under the Act.


                                       16
<PAGE>   17
                  (d) The Company will furnish to the Representatives and
         counsel for the Underwriters signed copies of the Registration
         Statement (including exhibits thereto) and to each other Underwriter a
         copy of the Registration Statement (without exhibits thereto) and, so
         long as delivery of a prospectus by an Underwriter or dealer may be
         required by the Act, as many copies of each Preliminary Prospectus and
         the Prospectus and any supplement thereto as the Representatives may
         reasonably request.

                  (e) The Company will arrange, if necessary, for the
         qualification of the Securities for sale under the laws of such
         jurisdictions as the Representatives may designate and will maintain
         such qualifications in effect so long as required for the distribution
         of the Securities; provided, however, that in no event shall the
         Company be obligated to qualify to do business in any jurisdiction
         where it is not now so qualified or to take any action that would
         subject it to service of process in suits, other than those arising out
         of the offering or sale of the Securities, in any jurisdiction where it
         is not now so subject.

                  (f) The Company will not, without the prior written consent of
         First Union Capital Markets Corp., for a period of 180 days following
         the Execution Time, offer, sell or contract to sell, or otherwise
         dispose of (or enter into any transaction which is designed to, or
         might reasonably be expected to, result in the disposition (whether by
         actual disposition or effective economic disposition due to cash
         settlement or otherwise) by the Company or any affiliate of the Company
         or any person in privity of contract with the Company or any affiliate
         of the Company) directly or indirectly, or announce the offering of,
         any other shares of Common Stock or any securities convertible into, or
         exchangeable for, shares of Common Stock; provided, however, that the
         Company may issue and sell Common Stock and options to purchase Common
         Stock pursuant to any employee stock option plan, stock ownership plan
         or dividend reinvestment plan of the Company in effect at the Execution
         Time, the Company may issue Common Stock issuable upon the conversion
         of securities or the exercise of warrants outstanding at the Execution
         Time, the Company may issue and distribute Reorganization Shares to
         Distributees pursuant to the Plan and the Company may make the other
         stock and option issuances described in the Prospectus.

                  (g) Neither the Company, the Exchange or any MIIX Subsidiary
         will take, directly or indirectly, any action designed to or which has
         constituted or which might reasonably be expected to cause or result,
         under the Exchange Act or otherwise, in stabilization or manipulation
         of the price of any security of the Company to facilitate the sale or
         resale of the Securities or the Reorganization Shares.

                  (h) Each MIIX Entity, jointly and severally, agrees to pay the
         costs and expenses relating to the following matters: (i) the
         preparation, printing or reproduction and filing with the Commission of
         the Registration Statement (including financial statements and exhibits
         thereto), each Preliminary Prospectus, the Prospectus, and each
         amendment or supplement to any of them; (ii) the printing (or
         reproduction) and delivery (including postage, air freight charges and
         charges for counting and packaging) of such copies of the Registration
         Statement, each Preliminary Prospectus, the Prospectus, and all
         amendments or supplements to any of them, as may, in each case, be
         reasonably


                                       17
<PAGE>   18
          requested for use in connection with the offering and sale of the
          Securities; (iii) the preparation, printing, authentication, issuance
          and delivery of certificates for the Securities, including any stamp
          or transfer taxes in connection with the original issuance and sale of
          the Securities; (iv) the printing (or reproduction) and delivery of
          this Agreement, any blue sky memorandum and all other agreements or
          documents printed (or reproduced) and delivered in connection with the
          offering of the Securities; (v) the registration of the Securities
          under the Exchange Act and the listing of the Securities on the New
          York Stock Exchange; (vi) any registration or qualification of the
          Securities for offer and sale under the securities or blue sky laws of
          the several states (including filing fees and the fees and expenses of
          counsel for the Underwriters relating to such registration and
          qualification); (vii) any filings required to be made with the
          National Association of Securities Dealers, Inc. (including filing
          fees and the fees and expenses of counsel for the Underwriters
          relating to such filings); (viii) the transportation and other
          expenses incurred by or on behalf of representatives of the Company,
          the Exchange or any MIIX Subsidiary in connection with presentations
          to prospective purchasers of the Securities; (ix) the fees and
          expenses of the Company's, the Exchange's and each MIIX Subsidiary's
          accountants and the fees and expenses of counsel (including local and
          special counsel) for each of the Company, the Exchange and each MIIX
          Subsidiary; (x) all other costs and expenses incident to the
          performance by the Company of its obligations hereunder; (xi) all
          costs and expenses incurred in connection with the Reorganization; and
          (xii) all stamp duties, similar taxes or duties or other taxes, if
          any, incurred by First Union in connection with the Directed Share
          Program; provided, however, that the fees and expenses of counsel for
          the Underwriters referenced in (vi) and (vii) above shall not exceed
          $10,000 in the aggregate.

                  (i) Each MIIX Entity will use its best efforts to (i) effect
         the listing of the Securities and the Reorganization Shares on the New
         York Stock Exchange and (ii) to obtain an "A" (Excellent) rating by
         A.M. Best for MIIX Insurance and for LP&C.

                  (j) Prior to or contemporaneously with the Closing Date, the
         Company, the Exchange and each MIIX Subsidiary will each use its best
         efforts to take all actions necessary in order to consummate the Plan
         and the transactions contemplated thereby.

                  (k) In connection with the Directed Share Program, each MIIX
         Entity will ensure that the Directed Shares will be restricted to the
         extent required by the National Association of Securities Dealers, Inc.
         (the "NASD") or the NASD rules from sale, transfer, assignment, pledge
         or hypothecation for a period of three months following the date of the
         effectiveness of the Registration Statement. First Union will notify
         the Company as to which Participants will need to be so restricted. The
         Company will direct the removal of the transfer restrictions upon the
         expiration of such period of time.


                  6. Conditions to the Obligations of the Underwriters. The
obligations of the Underwriters to purchase the Underwritten Securities and the
Option Securities, as the case may be, shall be subject to the accuracy of the
representations and warranties on the part of the MIIX Entities contained herein
as of the Execution Time, the Closing Date and any settlement date pursuant to
Section 3 hereof, to the accuracy of the statements of the MIIX Entities made in

         effective not later than (i) 6:00 PM New York City time on the date of
         determination of the public offering price, if such determination
         occurred at or prior to 3:00 PM New York City time on such date or (ii)

         or any supplement thereto, is required pursuant to Rule 424(b), the
         Prospectus, and any such supplement, will be filed in the manner and

                    entitled to preemptive or other rights to subscribe for the
                    Securities and, except as set forth in the Prospectus, to
                    the knowledge of such counsel, no options, warrants or other
                    rights to purchase, agreements or other obligations to
                    issue, or rights to convert any obligations into or exchange
                    any securities for, shares of capital stock of or ownership
                    interests in the Company or any Significant Subsidiary are
                    outstanding;

                         (iv) the Registration Statement has become effective
                    under the Act; any required filing of the Prospectus, and
                    any supplements thereto, pursuant to Rule 424(b) has been
                    made in the manner and within the time period required by
                    Rule 424(b); to the knowledge of such counsel, no stop order
                    suspending the effectiveness of the Registration Statement
                    has been issued, no proceedings for that purpose have been
                    instituted or threatened and the Registration Statement and
                    the Prospectus (other than the financial statements and
                    other financial information contained therein, as to which
                    such counsel need express no opinion) comply as to form in
                    all material respects with the applicable requirements of
                    the Act and the rules thereunder; and such counsel has no
                    reason to believe that on the Effective Date or at the
                    Execution Time the Registration Statement contained any
                    untrue statement of a material fact or omitted to state any
                    material fact required to be stated therein or necessary to
                    make the statements therein not misleading or that the
                    Prospectus as of its date or on the Closing Date included or
                    includes any untrue statement of a material fact or omitted
                    or omits to state a material fact necessary to make the
                    statements therein, in the light of the circumstances under
                    which they were made, not misleading (in each case, other
                    than the financial statements and other financial
                    information contained therein, as to which such counsel need
                    express no opinion);

                         (v) this Agreement has been duly authorized, executed
                    and delivered by each MIIX Entity;

                         (vi) the Company has full corporate power and authority
                    to execute and deliver the Stock Purchase Agreement and to
                    perform its respective obligations thereunder; each of the
                    Company and MIIX Insurance has full corporate power and
                    authority to execute and deliver each Assumption Agreement
                    and to perform its respective obligations thereunder; each
                    of the Assumption Agreements and the Stock Purchase
                    Agreement has been duly authorized, executed and delivered
                    by each MIIX Entity that is a party thereto and constitutes
                    a valid and binding obligation of each such MIIX Entity
                    enforceable in accordance with its terms, except as such
                    enforceability may be limited by bankruptcy, insolvency,
                    moratorium or similar laws now or hereafter in effect
                    relating to creditors' rights

                    generally, and by general principles of equity (regardless
                    of whether enforceability is considered in a proceeding at
                    law or in equity);

                         (vii) neither the Company nor any of the MIIX
                    Subsidiaries is and, after giving effect to the offering and
                    sale of the Securities and/or the Reorganization Shares and
                    the application of the proceeds thereof as described in the
                    Prospectus, will be an "investment company" or an entity
                    "controlled" by an "investment company", as such terms are
                    defined in the Investment Company Act of 1940, as amended;

                         (viii) no consent, approval, authorization, filing with
                    or order of any court or governmental agency or body is
                    required in connection with the sale of the Securities and
                    other agreements in the Underwriting Agreement, except such
                    as have been obtained and are in full force and effect under
                    the Act and such as may be required under the state
                    securities laws or insurance laws of any jurisdiction or the
                    rules of the National Association of Securities Dealers,
                    Inc. in connection with the purchase and distribution of the
                    Securities by the Underwriters in the manner contemplated in
                    this Agreement and in the Prospectus, and such other
                    approvals (specified in such opinion) as have been obtained;

                         (ix) to the knowledge of such counsel, no person has
                    rights to the registration of any securities of the Company
                    (owned or to be owned by such person) under the Registration
                    Statement;

                         (x) the Distribution Registration Statement has become
                    effective under the Act; any required filing of the
                    Distribution Prospectus, and any supplement thereto,
                    pursuant to Rule 424(b) has been made in the manner and
                    within the time period required by Rule 424(b); to the
                    knowledge of such counsel, no stop order suspending the
                    effectiveness of the Distribution Registration Statement has
                    been issued, no proceedings for that purpose have been
                    instituted or threatened; and such counsel has no reason to
                    believe that on the Distribution Effective Date or the
                    Special Meeting Date, the Distribution Registration
                    Statement contained any untrue statement of a material fact
                    or omitted to state any material fact required to be stated
                    therein or necessary to make the statements therein not
                    misleading or that the Distribution Prospectus, on the
                    Distribution Effective Date or the Special Meeting Date,
                    included any untrue statement of a material fact or omitted
                    to state a material fact necessary to make the statements
                    therein, in the light of the circumstances under which they
                    were made, not misleading (in each case, other than the
                    financial statements and other financial information
                    contained therein, as to which such counsel need express no
                    opinion); and

                         (xi) neither the issue and sale of the Securities or
                    the Reorganization Shares nor the consummation of any other
                    of the transactions contemplated herein or in the Plan nor
                    the fulfillment of the terms hereof or thereof will conflict
                    with, result in a breach or violation of or imposition of
                    any lien, charge or encumbrance upon any property or assets
                    of the Company, any Significant Subsidiary or the


                                       21

                    Exchange pursuant to, (i) the charter, by-laws or any other
                    organizational document of the Company, any Significant
                    Subsidiary or the Exchange, (ii) the terms of any indenture,
                    contract, lease, mortgage, deed of trust, note agreement,
                    loan agreement or other agreement filed as an exhibit to the
                    Registration Statement, or (iii) any statute, law, rule,
                    regulation, judgment, order or decree applicable to the
                    Company, any Significant Subsidiary or the Exchange (other
                    than those pertaining to insurance laws and regulations, as
                    to which such counsel need express no opinion) of any
                    Federal or New Jersey court, regulatory body, administrative
                    agency, governmental body, arbitrator or other authority
                    having jurisdiction over the Company, any Significant
                    Subsidiary or the Exchange or any of their respective
                    properties, which violation or default would, in the case of
                    clause (ii) and (iii) above, either individually or in the
                    aggregate with all other violations and defaults referred to
                    in this paragraph (xi) (if any), have a Material Adverse
                    Effect.

         Such opinion shall also cover any other matters reasonably requested by
         the Representatives. In rendering such opinion, such counsel may rely
         (A) as to matters involving the application of laws of any jurisdiction
         other than the States of Delaware, New Jersey, New York, or the Federal
         laws of the United States, to the extent they deem proper and specified
         in such opinion, upon the opinion of other counsel of good standing
         whom they believe to be reliable and who are satisfactory to counsel
         for the Underwriters and (B) as to matters of fact, to the extent they
         deem proper, on certificates of responsible officers of the Company and
         public officials. References to the Prospectus in this paragraph (b)
         include any supplements thereto at the Closing Date.

                  (c) The Company shall have requested and caused Verice M.
         Mason, Esq., Vice President, Regulatory Affairs, of the
         Attorney-in-Fact, to have furnished to the Representatives her opinion,
         dated the Closing Date and addressed to the Representatives, to the
         effect that:

                           (i) to the knowledge of such counsel, there is no
                  pending or threatened action, suit or proceeding by or before
                  any court or governmental agency, authority or body or any
                  arbitrator involving the Company, the Exchange, any
                  Significant Subsidiary or their respective property of a
                  character required to be disclosed in the Registration
                  Statement which is not adequately disclosed in the Prospectus,
                  and there is no franchise, contract or other document of a
                  character required to be described in the Registration
                  Statement or Prospectus, or to be filed as an exhibit thereto,
                  which is not described or filed as required;

                           (ii) the statements included in the Prospectus under

                  Distribution", " -- Regulatory Approvals", "Risk Factors --
                  Actions Opposing the Plan of Reorganization", " -- Regulatory

                  Approvals", "The Reorganization", "Business -- Regulation", "
                  -- Litigation" fairly summarize the matters therein described;

                           (iii) each of the Company, the Exchange and the
                  Significant Subsidiaries owns, possesses or has obtained all
                  licenses, certificates, permits, consents, orders, approvals
                  and other authorizations issued by the appropriate federal,
                  state or foreign regulatory authorities necessary to conduct
                  its business as currently conducted and to own or lease, as
                  the case may be, and to operate its properties, and neither
                  the Company, the Exchange nor any such Significant Subsidiary
                  has received any notice of any proceeding relating to the
                  revocation or modification of any such license, certificate,
                  permit, consent, order, approval or authorization which,
                  singly or in the aggregate, if the subject of an unfavorable
                  decision, ruling or finding, would have a Material Adverse
                  Effect, except as set forth in or contemplated in the
                  Prospectus (exclusive of any supplement thereto);

                           (iv) the Exchange has full power and authority to
                  execute and deliver each Assumption Agreement and the Plan and
                  to perform its obligations thereunder; the Plan has been duly
                  authorized and executed by the Exchange;

                           (v) each of the Company, the Exchange, the
                  Significant Subsidiaries and MIIX New York is duly organized
                  and licensed as an insurance or insurance holding company in
                  its respective jurisdiction of organization or incorporation,
                  as the case may be, and none of the Company, the Exchange and
                  the Significant Subsidiaries has received any notification
                  from any insurance regulatory authority to the effect that any
                  additional authorization, approval, order, consent, license,
                  certificate, permit, registration or qualification from such
                  insurance regulatory authority is needed to be obtained; each
                  of the Company, the Exchange and the Significant Subsidiaries
                  is duly licensed and authorized (and MIIX New York is duly
                  licensed) to conduct its insurance business under the
                  insurance laws of each jurisdiction in which it conducts such
                  business so as to require such licensing and authorization;
                  all such licenses and authorizations are in full force and
                  effect, the Company, the Exchange, each Significant Subsidiary
                  and MIIX New York have fulfilled and performed all obligations
                  necessary to maintain such licenses and authorizations, and
                  there is no event or proceeding or, to such counsel's
                  knowledge, inquiry or investigation, that would reasonably be
                  expected to result in the suspension, revocation or limitation
                  of any such licenses or authorizations or otherwise impose any
                  limitation on the conduct of the business of the Company, the
                  Exchange, any Significant Subsidiary or MIIX New York, and
                  there is no sustainable basis for any such suspension,
                  revocation or limitation; each of the Company, the Exchange,
                  the Significant Subsidiaries and MIIX New York is in
                  compliance with, and conducts its business in conformity with,
                  all applicable insurance laws and regulations, except where
                  the failure to comply or conform with such laws and
                  regulations, would not, individually or in the aggregate, have
                  a Material Adverse Effect; the Company, the Exchange, each
                  Significant Subsidiary and MIIX New York have filed all
                  reports, information statements and other documents with the
                  insurance regulatory authorities of each jurisdiction which
                  requires any such filing and as are required to be filed
                  pursuant to the insurance statutes of such jurisdictions and
                  the rules and regulations of the insurance regulatory
                  authorities thereunder; based upon a review of (a) the stock
                  ledger of LP&C, (b) the minutes of meetings of the board of
                  directors and

                                       23
<PAGE>   24
                    stockholders of LP&C and (c) the officer's certificate
                    attached thereto as Exhibit A, all the outstanding shares of
                    capital stock of LP&C have been duly and validly authorized
                    and issued and are fully paid and nonassessable.

                         (vi) all reinsurance treaties and arrangements to which
                    the Exchange or any of the Insurance Subsidiaries is a party
                    are in full force and effect and neither the Exchange nor
                    any of the Insurance Subsidiaries is in violation of or in
                    default in the performance, observance or fulfillment of,
                    any obligation, agreement, covenant or condition contained
                    therein; upon the effectiveness of the Transfer, all such
                    treaties and arrangements to which the Exchange is a party
                    shall remain in full force and effect and inure to the
                    benefit of, and be enforceable by, MIIX Insurance; to the
                    knowledge of such counsel, after due inquiry, neither the
                    Company, the Exchange nor any of the Insurance Subsidiaries
                    has received any notice from any of the other parties to
                    such treaties or arrangements that such other party intends
                    not to perform such treaty or arrangement, except as would
                    not have a Material Adverse Effect;

                         (vii) the Exchange is a reciprocal insurance exchange
                    duly organized under the laws of the State of New Jersey and
                    is in compliance in all material respects with the
                    requirements of the insurance laws of the State of New
                    Jersey providing for the organization and regulation of
                    reciprocal insurance exchanges; and has full power and
                    authority to own or lease, as the case may be, and to
                    operate its properties and conduct its business as described
                    in the Prospectus, and is duly qualified to do business as a
                    foreign corporation and is in good standing under the laws
                    of each jurisdiction which requires such qualification;

                         (viii) no consent, approval, authorization, filing with
                    or order of any court or governmental agency or body is
                    required under the Act, the New Jersey Insurance Law or the

                    Reorganization Shares nor the consummation of any other of
                    the transactions contemplated herein or in the Plan nor the
                    fulfillment of the terms hereof or thereof will conflict
                    with, result in a breach or violation of or imposition of
                    any lien, charge or encumbrance upon any property or assets
                    of the Company, any Significant Subsidiary or the Exchange
                    pursuant to, (i) the terms of any indenture, contract,
                    lease, mortgage, deed of trust, note agreement, loan
                    agreement or other agreement filed as an exhibit to the
                    Registration Statement to which the Company, the Exchange or
                    a Significant Subsidiary is a party, or (ii) any statute,
                    law, rule, regulation, judgment, order or decree applicable
                    to the Company, any Significant Subsidiary or the Exchange
                    of any court, regulatory body, administrative agency,
                    governmental body, arbitrator or other authority having
                    jurisdiction over the Company, any Significant Subsidiary or
                    the Exchange or any of their respective properties, which
                    violation or default would, in the case of clause (i) and
                    (ii) above, either individually or in the aggregate with all
                    other violations and defaults referred to in this paragraph
                    (ix) (if any), have a Material Adverse Effect;

                         (xi) all necessary approvals under the New Jersey
                    Insurance Law or otherwise for the consummation of the
                    transactions contemplated by the Plan or for the
                    effectiveness of the Plan have been obtained; no other
                    actions are required to occur and no other conditions are
                    required to be satisfied pursuant to the New Jersey
                    Insurance Law at or prior to the Plan Effective Time in
                    order for the Plan and the transactions contemplated thereby
                    to be effective, except those actions or conditions that
                    have occurred or been satisfied; the Reorganization
                    (including, without limitation, the Distribution, the
                    Purchase and the Transfer) does not conflict with the New
                    Jersey Insurance Law;

                         (xii) MIIX Insurance has obtained regulatory approval
                    to become an admitted carrier in the states of Connecticut,
                    Delaware, Kentucky, Maryland, Michigan, New Jersey,
                    Pennsylvania, Vermont and West Virginia. MIIX Insurance has
                    also obtained regulatory approval to use the rates, rules
                    and policy forms previously used by the Exchange in each of
                    those states. The state of Virginia has approved the change
                    in LP&C's ultimate parent from the Exchange to the Company
                    and the state of New York has approved the change in MIIX
                    New York's ultimate parent from the Exchange to the Company.
                    The appropriate regulatory bodies in the states of
                    Connecticut, Delaware and West Virginia have approved the
                    assignment to MIIX Insurance of all reinsurance agreements
                    to which the Exchange is a party, and the reinsurers to such
                    agreements have consented to such assignment; and

                         (xiii) the opinions expressed above in (x) reflect such
                    counsel's judgment that a New Jersey court, upon examination
                    of all relevant facts and law, in a case in which the issues
                    were properly briefed and argued, should conclude that the
                    Commissioner had the inherent power and authority pursuant
                    to applicable New Jersey Insurance Law to approve the Plan
                    and issue the Order, notwithstanding the absence of specific
                    statutory authority governing the


                                       25

                    reorganization of New Jersey domestic reciprocal insurance
                    exchanges into New Jersey domestic stock insurers.

         In rendering such opinion, such counsel may rely (A) as to matters
         involving the application of laws of any jurisdiction other than the
         State of New Jersey or the Federal laws of the United States, to the
         extent such counsel deems proper and specified in such opinion, upon
         the opinion of other counsel of good standing whom such counsel
         believes to be reliable and who are satisfactory to counsel for the
         Underwriters and (B) as to matters of fact, to the extent such counsel
         deems proper, on certificates of responsible officers of the Company
         and public officials. References to the Prospectus in this paragraph
         (c) include any supplements thereto at the Closing Date.

                  (d) The Company shall have requested and caused Debevoise &
         Plimpton, Special Reorganization Counsel for the Company and the
         Exchange, to have furnished to the Representatives their opinion dated
         the Closing Date and addressed to the Representatives, to the effect
         that:

                           (i) the Plan and the transactions contemplated
                  thereby (including, without limitation, the Distribution, the
                  Purchase and the Transfer) do not violate New Jersey Insurance
                  Law; all necessary approvals which are required by the terms
                  of the Order for the consummation of the transactions
                  contemplated by the Plan or for the effectiveness of the Plan
                  have been obtained; each of the actions required to occur and
                  conditions required to be satisfied at or prior to the Plan
                  Effective Time pursuant to the Order or the Plan have occurred
                  or been satisfied; the Reorganization (including, without
                  limitation, the Distribution, the Purchase and the Transfer)
                  has been completed in accordance with the Plan and the Order,
                  and all the rights (including, without limitation, rights in
                  respect of contracts, reinsurance treaties, leases, licenses
                  and trademarks) and properties of the Exchange have accrued
                  to, and become the rights and properties of, MIIX Insurance,
                  and all the rights of creditors and liens of the Exchange have
                  become the rights of creditors and liens of MIIX Insurance;

                           (ii) neither the issue and sale of the Securities nor
                  the consummation of any other of the transactions contemplated
                  herein nor the fulfillment of the terms hereof or thereof will
                  conflict with or result in a violation of the Order or the
                  Plan; and

                         (iii) the opinions expressed above in (i) and (ii)
                    reflect such firm's judgment that a New Jersey court, upon
                    examination of all relevant facts and law, in a case in
                    which the issues were properly briefed and argued, should
                    conclude that the Commissioner had the inherent power and
                    authority pursuant to applicable New Jersey Insurance Law to
                    approve the Plan and issue the Order, notwithstanding the
                    absence of specific statutory authority governing the
                    reorganization of New Jersey domestic reciprocal insurance
                    exchanges into New Jersey domestic stock insurers.

         opinion of other counsel of good standing whom they believe to be
         reliable and who are satisfactory to counsel for the Underwriters and
         (B) as to matters of fact, to the extent they deem proper, on

         the Representatives, confirming that they are independent accountants
         within the meaning of the Act and the applicable published rules and
         regulations thereunder and that they have performed a review of the
         unaudited interim financial information of the Exchange and its
         subsidiaries for the three-month period ended March 31, 1999, and as at
         March 31, 1999, in accordance with Statement on Auditing Standards No.
         71 and stating in effect that:

<PAGE>   29
                           (i) in their opinion the audited financial statements
                  and financial statement schedules included in the Registration

                  to form in all material respects with the applicable
                  accounting requirements of the Act and the related published
                  rules and regulations;

                           (ii) on the basis of a reading of the latest
                  unaudited financial statements made available by the Exchange
                  and its subsidiaries; their limited review, in accordance with
                  standards established under Statement on Auditing Standards
                  No. 71, of the unaudited interim financial information for the

                  1999, as indicated in their report dated May 12, 1999;
                  carrying out certain specified procedures (but not an
                  examination in accordance with generally accepted auditing
                  standards) which would not necessarily reveal matters of
                  significance with respect to the comments set forth in such
                  letter; a reading of the minutes of the meetings of the Board
                  of Governors and the members of the Exchange, the board of
                  directors and the stockholders of each of the Exchange's

                  finance committees) of the Exchange and each of its
                  subsidiaries; and inquiries of certain officials of the

                  subsidiaries as to transactions and events subsequent to
                  December 31, 1998, nothing came to their attention which
                  caused them to believe that:

                                    (1) any unaudited financial statements
                           included in the Registration Statement and the
                           Prospectus do not comply as to form in all material
                           respects with applicable accounting requirements of
                           the Act and with the published rules and regulations
                           of the Commission with respect to registration
                           statements on Form S-1; and said unaudited financial
                           statements are not in conformity with generally
                           accepted accounting principles applied on a basis
                           substantially consistent with that of the audited
                           consolidated financial statements included in the
                           Registration Statement and the Prospectus;

                                    (2) with respect to the period subsequent to
                           March 31, 1999, there was any decrease, at a
                           specified date not more than five days prior to the
                           date of the letter, in the total assets or total
                           equity of the Exchange and its subsidiaries or any
                           increase in the total liabilities of the Exchange and
                           its subsidiaries, as compared with the amounts shown
                           on the March 31, 1999 consolidated balance sheet
                           included in the Registration Statement and the
                           Prospectus, or for the period from April 1, 1999 to
                           such specified date there were any decreases, as
                           compared with the corresponding period in the
                           preceding year or in the preceding quarter, in net
                           premiums earned, net investment income, net realized
                           investment gains, income before income taxes and net
                           income of the Exchange and its subsidiaries, except
                           in all instances for increases or decreases set forth
                           in such letter, in which case the letter shall be
                           accompanied by an explanation by the Exchange


                                       29
<PAGE>   30
                           and its subsidiaries, as to the significance thereof
                           unless said explanation is not deemed necessary by
                           the Representatives; or

                                    (3) the information included in the
                           Registration Statement and Prospectus in response to
                           Regulation S-K, Item 301 (Selected Financial Data),
                           Item 302 (Supplementary Financial Information) and
                           Item 402 (Executive Compensation) is not in
                           conformity with the applicable disclosure
                           requirements of Regulation S-K; and

                           (iii) they have performed certain other specified
                  procedures as a result of which they determined that certain
                  information of an accounting, financial or statistical nature
                  (which is limited to accounting, financial or statistical
                  information derived from the general accounting records of the
                  Exchange and its subsidiaries) set forth in the Registration
                  Statement and the Prospectus, including, without limitation,
                  the information set forth under the captions "Summary
                  Financial and Operating Data", "Selected Financial and
                  Operating Data" and "Management's Discussion and Analysis of
                  Financial Condition and Results of Operations" in the
                  Prospectus, agrees with the accounting records of the Exchange
                  and its subsidiaries, excluding any questions of legal
                  interpretation.

References to the Prospectus in this paragraph (h) include any supplement
thereto at the date of the letter.

The Representative shall have also received from Ernst & Young LLP a letter
stating that the Exchange's and its subsidiaries' system of internal accounting
controls taken as a whole is sufficient to meet the broad objectives of internal
accounting control insofar as those objectives pertain to the prevention or
detection of errors or irregularities in amounts that would be material in
relation to the consolidated financial statements of the Exchange and its
subsidiaries.

     (i) Subsequent to the Execution Time or, if earlier, the dates as of which
information is given in the Registration Statement (exclusive of any
post-effective amendment thereof) and the Prospectus (exclusive of any
supplement thereto), there shall not have been (i) any change or decrease
specified in the letter or letters referred to in paragraph (h) of this Section
6 or (ii) any change, or any development involving a prospective change, in or
affecting the condition (financial or otherwise), earnings, business or
properties of the Company, the Exchange and the MIIX Subsidiaries, taken as a
whole, whether or not arising from transactions in the ordinary course of
business, except as set forth in or contemplated in the Prospectus (exclusive of
any supplement thereto) the effect of which, in any case referred to in clause
(i) or (ii) above, is, in the sole judgment of the Representatives, so material
and adverse as to make it impractical or inadvisable to proceed with the
offering or delivery of the Securities as contemplated by the Registration
Statement (exclusive of any post-effective amendment thereof) and the Prospectus
(exclusive of any supplement thereto).

<PAGE>   31
                  (j) The Securities and the Reorganization Shares shall have
         been listed and admitted and authorized for trading on the New York
         Stock Exchange, and satisfactory evidence of such actions shall have
         been provided to the Representatives.

                  (k) At the Execution Time, the Company shall have furnished to
         the Representatives a letter substantially in the form of Exhibit A
         hereto from each officer and director of the Company addressed to the
         Representatives.

                  (l) The Exchange and LP&C shall have an "A" (Excellent) rating
         by A.M. Best and there shall not have been any decrease in the rating
         of any of the Exchange or LP&C by A.M. Best, or any notice given of any
         intended or potential decrease in any such rating or of a possible
         change in any such rating that does not indicate the direction of the
         possible change. The Representatives shall not have any reasonable
         basis on which to conclude that MIIX Insurance and LP&C will not obtain
         an "A" (Excellent) rating by A.M. Best immediately after the Plan
         Effective Time.

                  (m) The Plan shall not have been revoked, rescinded, modified
         or withdrawn, and prior to or contemporaneously with the Closing Date,
         each of the actions required to occur and conditions required to be
         satisfied at or prior to the Plan Effective Time pursuant to the New
         Jersey Insurance Law, the Plan or the Order shall have occurred or been
         satisfied and the transactions contemplated by the Plan (including,
         without limitation, the Distribution, the Purchase and the Transfer)
         shall have been consummated in accordance with the New Jersey Insurance
         Law, the Order and the Plan.

                  (n) Prior to the Closing Date, the Company shall have
         furnished to the Representatives such further information, certificates
         and documents as the Representatives may reasonably request.

                  If any of the conditions specified in this Section 6 shall not
have been fulfilled in all material respects when and as provided in this
Agreement, or if any of the opinions and certificates mentioned above or
elsewhere in this Agreement shall not be in all material respects reasonably
satisfactory in form and substance to the Representatives and counsel for the
Underwriters, this Agreement and all obligations of the Underwriters hereunder
may be canceled at, or at any time prior to, the Closing Date by the
Representatives. Notice of such cancellation shall be given to the Company in
writing or by telephone or facsimile confirmed in writing.

                  The documents required to be delivered by this Section 6 shall
be delivered at the offices of Cleary, Gottlieb, Steen & Hamilton on the Closing
Date.

                  7. Reimbursement of Underwriters' Expenses. If the sale of the
Securities provided for herein is not consummated because any condition to the
obligations of the Underwriters set forth in Section 6 hereof is not satisfied,
because of any termination pursuant to Section 10 hereof or because of any
refusal, inability or failure on the part of any MIIX Entity to perform any
agreement herein or comply with any provision hereof other than by reason of a
default by any of the Underwriters, each MIIX Entity agrees, jointly and
severally, that it will reimburse the Underwriters severally through First Union
Capital Markets Corp. on demand for


                                       31
<PAGE>   32
all out-of-pocket expenses (including reasonable fees and disbursements of
counsel) that shall have been incurred by them in connection with the proposed
purchase and sale of the Securities.

                  8. Indemnification and Contribution. (a)(i) The MIIX Entities,
jointly and severally, agree to indemnify and hold harmless each Underwriter,
the directors, officers, employees and agents of each Underwriter and each
person who controls any Underwriter within the meaning of either the Act or the
Exchange Act against any and all losses, claims, damages or liabilities, joint
or several, to which they or any of them (each an "Underwriter Indemnitee" and
together the "Underwriter Indemnitees") may become subject under the Act, the
Exchange Act or other Federal or state statutory law or regulation, at common
law or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) relate to, arise out of or are in connection with or
are based upon (A) the engagement under the Engagement Letter dated March 25,
1999 between the Exchange and First Union Capital Markets Corp. (the "Engagement
Letter") or any transaction or conduct in connection therewith, or (B) the
engagement under this Agreement or any transaction or conduct in connection
therewith (including, without limitation, the Directed Share Program), and agree
to reimburse each such indemnified party, as incurred, for any legal or other
expenses reasonably incurred by them in connection with investigating,
preparing, pursuing or defending any action, claim, suit, investigation or
proceeding related to, arising out of or in connection with or based upon (A)
the engagement under the Engagement Letter or any transaction or conduct in
connection therewith, or (B) the engagement under this Agreement or any
transaction or conduct in connection therewith (including, without limitation,
the Directed Share Program), in each case, whether or not pending or threatened
and whether or not any Underwriter Indemnitee is a party to such action, claim,
suit, investigation or proceeding; provided, however, that no indemnification
will be made pursuant to this clause (i) in respect of liability that is
determined by a court of competent jurisdiction by final and nonappealable
judgment to have resulted primarily from an Underwriter Indemnitee's gross
negligence or willful misconduct; provided further that in the event that fees
or expenses have been advanced to or paid on behalf of an Underwriter Indemnitee
who is determined not to be entitled to indemnification hereunder, the
Underwriter Indemnitee shall reimburse the MIIX Entities for any such amounts
advanced or paid. Each MIIX Entity also agrees that no Underwriter Indemnitee
shall have any liability (whether direct or indirect, in contract, tort or
otherwise) to such MIIX Entity or any person asserting claims on such MIIX
Entity's behalf or otherwise in connection with any matter referred to in the
Engagement Letter or this Agreement. This indemnity agreement will be in
addition to any liability which each MIIX Entity may otherwise have.

                  (ii) Notwithstanding the immediately preceding clause (i), the
MIIX Entities, jointly and severally, agree to indemnify and hold harmless,
under all circumstances and without regard to whether indemnification is
available pursuant to such clause (i), each Underwriter Indemnitee against any
and all losses, claims, damages or liabilities, joint or several, to which such
Underwriter Indemnitee may become subject under the Act, the Exchange Act or
other Federal or state statutory law or regulation, at common law or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in the registration statement for the
registration of the Securities as originally filed or in any amendment thereof,
or in any Preliminary Prospectus or the Prospectus, or in any amendment thereof
or supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not


                                       32
<PAGE>   33
misleading, and agree to reimburse each such indemnified party, as incurred, for
any legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided, however, that each MIIX Entity will not be liable in any such case to
the extent that any such loss, claim, damage or liability arises out of or is
based upon any such untrue statement or alleged untrue statement or omission or
alleged omission made in the registration statement for the registration of the
Securities as originally filed or in any amendment thereof, or in any
Preliminary Prospectus or the Prospectus, or in any amendment thereof or
supplement thereto, in each case, in reliance upon and in conformity with
written information furnished to the Company by or on behalf of any Underwriter
through the Representatives specifically for inclusion therein; provided
further, that with respect to any untrue statement or omission of material fact
made in any Preliminary Prospectus, the indemnity agreement contained in this
Section 8(a) (ii) shall not inure to the benefit of any Underwriter from whom
the person asserting any such loss, claim, damage or liability purchased the
securities concerned, to the extent that any such loss, claim, damage or
liability of such Underwriter occurs under the circumstance where it shall have
been determined by a court of competent jurisdiction by final and nonappealable
judgment that (w) the Company had previously furnished copies of the Prospectus
to the Representatives in the requisite quantity and on a timely basis to permit
proper delivery at or prior to the written confirmation of the sale of such
securities to such person, (x) delivery of the Prospectus was required by the
Act to be made to such person, (y) the untrue statement or omission of a
material fact contained in the Preliminary Prospectus was corrected in the
Prospectus and (z) there was not sent or given to such person, at or prior to
the written confirmation of the sale of such securities to such person, a copy
of the Prospectus. This indemnity agreement will be in addition to any liability
which each MIIX Entity may otherwise have.

                  (b) Each Underwriter severally and not jointly agrees to
indemnify and hold harmless each MIIX Entity, each of its directors, each of its
officers, if any, who signs the Registration Statement, and each person who
controls each MIIX Entity within the meaning of either the Act or the Exchange
Act, (each a "Company Indemnitee" and together the "Company Indemnitees") to the
same extent as the indemnity contained in clause (ii) of paragraph (a) of this
Section 8 from the MIIX Entities to each Underwriter, but only with reference to
written information relating to such Underwriter furnished to the Company by or
on behalf of such Underwriter through the Representatives specifically for
inclusion in the registration statement for the registration of the Securities
as originally filed or in any amendment thereof, or in any Preliminary
Prospectus or the Prospectus, or in any amendment thereof or supplement thereto.
This indemnity agreement will be in addition to any liability which any
Underwriter may otherwise have. Each MIIX Entity acknowledges that the
statements set forth in the last paragraph of the cover page regarding delivery
of the Securities, the legend in block capital letters on page [2] related to
stabilization, syndicate covering transactions and penalty bids and, under the
heading "Underwriting" (i) the sentences related to concessions and
reallowances, (ii) the sentence relating to the Underwriter's intent with
respect to confirming sales to accounts over which they exercise discretionary
authority, and (iii) the paragraph related to stabilization, syndicate covering
transactions and penalty bids in any Preliminary Prospectus and the Prospectus
constitute the only information furnished in writing by or on behalf of the
several Underwriters for inclusion in any Preliminary Prospectus or the
Prospectus.


                                       33
<PAGE>   34
                  (c) Promptly after receipt by an indemnified party under this
Section 8 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 8, notify the indemnifying party in writing of the
commencement thereof; but the failure so to notify the indemnifying party (i)
will not relieve it from liability under paragraph (a) or (b) above unless and
to the extent it did not otherwise learn of such action and such failure results
in the forfeiture by the indemnifying party of substantial rights and defenses
and (ii) will not, in any event, relieve the indemnifying party from any
obligations to any indemnified party other than the indemnification obligation
provided in paragraph (a) or (b) above. The indemnifying party shall be entitled
to appoint counsel of the indemnifying party's choice at the indemnifying
party's expense to represent the indemnified party in any action for which
indemnification is sought (in which case the indemnifying party shall not
thereafter be responsible for the fees and expenses of any separate counsel
retained by the indemnified party or parties except as set forth below);
provided, however, that such counsel shall be satisfactory to the indemnified
party. Notwithstanding the indemnifying party's election to appoint counsel to
represent the indemnified party in an action, the indemnified party shall have
the right to employ separate counsel (including local counsel), and the
indemnifying party shall bear the reasonable fees, costs and expenses of such
separate counsel if (i) the use of counsel chosen by the indemnifying party to
represent the indemnified party would present such counsel with a conflict of
interest, (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party, (iii) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of the institution of such action or (iv) the indemnifying party
shall authorize the indemnified party to employ separate counsel at the expense
of the indemnifying party. It is understood, however, that the indemnifying
party shall, in connection with any one action or separate but substantially
similar or related actions in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for (i) the fees and expenses of
only one separate firm of attorneys (in addition to any local counsel) for the
Underwriter Indemnities, and (ii) the fees and expenses of only one separate
firm of attorneys (in addition to any local counsel) for the Company
Indemnitees. In the case of any such separate firm for the Company Indemnitees,
such firm shall be designated by the Company. In the case of any such separate
firm for the Underwriter Indemnitees, such firm shall be designated by First
Union Capital Markets Corp. An indemnifying party will not, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any pending or threatened claim,
action, suit or proceeding in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified parties are actual or
potential parties to such claim or action) unless such settlement, compromise or
consent includes an unconditional release of each indemnified party from all
liability arising out of such claim, action, suit or proceeding. An indemnifying
party shall not be liable under this Section 8 to any indemnified party
regarding any settlement or compromise or consent to the entry of any judgment
with respect to any pending or threatened claim, action, suit or proceeding in
respect of which indemnification or contribution may be sought hereunder
(whether or not the indemnified parties are actual or potential parties to such
claim, action, suit or proceeding) unless (i) such settlement, compromise or
consent is consented to by such indemnifying party, which consent shall not be
withheld


                                       34
<PAGE>   35
unless the settlement is unreasonable in light of all of the circumstances
surrounding such claim, action, suit or proceeding, or (ii) such settlement,
compromise or consent is entered into more than twenty business days after such
indemnifying party shall have received a request from such indemnified party for
reimbursement for the fees and expenses of counsel (in any case where such fees
and expenses are at the expense of such indemnifying party) and, prior to the
date of such settlement, compromise or consent, such indemnifying party shall
have failed to comply with such reimbursement request. If a MIIX Entity does
withhold its consent to a proposed settlement, compromise or consent to the
entry of a judgment, then the MIIX Entities will indemnify the Underwriter
Indemnities in accordance with clause (i) of paragraph (a) of this Section 8 and
clause (ii) of paragraph (a) of this Section 8, or if such indemnity is
unavailable for any reason, contribute in accordance with paragraph (d) of this
Section 8.


                  (d) In the event that the indemnity provided in paragraph (a)
or (b) of this Section 8 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the MIIX Entities, jointly and severally, and
the Underwriters severally agree to contribute to the aggregate losses, claims,
damages and liabilities (including legal or other expenses reasonably incurred
in connection with investigating or defending same) (collectively "Losses") to
which the MIIX Entities and one or more of the Underwriters may be subject in
such proportion as is appropriate to reflect the relative benefits received by
the MIIX Entities on the one hand and by the Underwriters on the other from the
offering of the Securities; provided, however, that in no case shall any
Underwriter (except as may be provided in any agreement among underwriters
relating to the offering of the Securities) be responsible for any amount in
excess of the underwriting discount or commission applicable to the Securities
purchased by such Underwriter hereunder. If the allocation provided by the
immediately preceding sentence is unavailable for any reason, the MIIX Entities,
jointly and severally, and the Underwriters severally shall contribute in such
proportion as is appropriate to reflect not only such relative benefits but also
the relative fault of the MIIX Entities, jointly and severally, on the one hand
and of the Underwriters on the other in connection with the statements or
omissions which resulted in such Losses as well as any other relevant equitable
considerations. Benefits received by the MIIX Entities shall be deemed to be
equal to the total net proceeds from the offering (before deducting expenses)
received by the Company, and benefits received by the Underwriters shall be
deemed to be equal to the total underwriting discounts and commissions, in each
case as set forth on the cover page of the Prospectus. Relative fault shall be
determined by reference to, among other things, whether any untrue or any
alleged untrue statement of a material fact or the omission or alleged omission
to state a material fact relates to information provided by any MIIX Entity on
the one hand or the Underwriters on the other, the intent of the parties and
their relative knowledge, access to information and opportunity to correct or
prevent such untrue statement or omission. The MIIX Entities and the
Underwriters agree that it would not be just and equitable if contribution were
determined by pro rata allocation or any other method of allocation which does
not take account of the equitable considerations referred to above.
Notwithstanding the provisions of this paragraph (d), no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. For purposes of this Section 8, each person who
controls an Underwriter within the meaning of either the Act or the Exchange Act
and each director, officer, employee and agent of an Underwriter shall have the
same rights to contribution as such Underwriter, and each person who controls a
MIIX Entity within the meaning of either


                                       35
<PAGE>   36
the Act or the Exchange Act, each officer of a MIIX Entity who shall have signed
the Registration Statement, if any, and each director of a MIIX Entity shall
have the same rights to contribution as such MIIX Entity, subject in each case
to the applicable terms and conditions of this paragraph (d).

                  9. Default by an Underwriter. If any one or more Underwriters
shall fail to purchase and pay for any of the Securities agreed to be purchased
by such Underwriter or Underwriters hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Underwriters shall be obligated severally to take up
and pay for (in the respective proportions which the amount of Securities set
forth opposite their names in Schedule I hereto bears to the aggregate amount of
Securities set forth opposite the names of all the remaining Underwriters) the
Securities which the defaulting Underwriter or Underwriters agreed but failed to
purchase; provided, however, that in the event that the aggregate amount of
Securities which the defaulting Underwriter or Underwriters agreed but failed to
purchase shall exceed 10% of the aggregate amount of Securities set forth in
Schedule I hereto, the remaining Underwriters shall have the right to purchase
all, but shall not be under any obligation to purchase any, of the Securities,
and if such nondefaulting Underwriters do not purchase all the Securities, this
Agreement will terminate without liability to any nondefaulting Underwriter or
to any MIIX Entity. In the event of a default by any Underwriter as set forth in
this Section 9, the Closing Date shall be postponed for such period, not
exceeding five Business Days, as the Representatives shall determine in order
that the required changes in the Registration Statement and the Prospectus or in
any other documents or arrangements may be effected. Nothing contained in this
Agreement shall relieve any defaulting Underwriter of its liability, if any, to
the MIIX Entities and any nondefaulting Underwriter for damages occasioned by
its default hereunder.

                  10. Termination. This Agreement shall be subject to
termination in the absolute discretion of the Representatives, by notice given
to the Company prior to delivery of and payment for the Securities, if at any
time prior to such time (i) trading in the Common Stock shall have been
suspended by the Commission or the New York Stock Exchange or trading in
securities generally on the New York Stock Exchange shall have been suspended or
limited or minimum prices shall have been established on such Exchange, (ii) a
banking moratorium shall have been declared either by Federal or New York State
authorities or (iii) there shall have occurred any outbreak or escalation of
hostilities, declaration by the United States of a national emergency or war, or
other calamity or crisis the effect of which on financial markets is such as to
make it, in the sole judgment of the Representatives, impractical or inadvisable
to proceed with the offering or delivery of the Securities as contemplated by
the Prospectus (exclusive of any supplement thereto).

                  11. Representations and Indemnities to Survive. The respective
agreements, representations, warranties, indemnities and other statements of the
