                                   ARTICLE III

DEFINITIONS

A.    Ultimate Net Loss

      "Ultimate Net Loss," as used in this Contract, shall mean the actual loss
      paid by the Company or for which the Company becomes liable to pay, such
      loss shall include 100% of any Loss in Excess of Policy Limits as defined
      in the LOSS IN EXCESS OF POLICY LIMITS ARTICLE, 100% of any Extra
      Contractual Obligations as defined in the EXTRA CONTRACTUAL OBLIGATIONS
      ARTICLE, ex-gratia payments subject to prior approval, expenses of
      litigation and interest, claim-specific declaratory judgment expenses, and
      all other loss expense of the Company including subrogation, salvage, and
      recovery expenses (office expenses and salaries of officials and employees
      not classified as loss adjusters are not chargeable as expenses for
      purposes of this paragraph), but salvages and all recoveries, including
      recoveries under all reinsurances, which inure to the benefit of this
      Contract (whether recovered or not), shall be first deducted from such
      loss to arrive at the amount of liability attaching hereunder.

                                                                   [WILLIS LOGO]

                                     Page 2

<PAGE>

      The phrase "ex-gratia payments" shall mean payments made as an
      accommodation by the Company in settlement of a claim for which no
      coverage exists under the Policy reinsured hereunder, subject to the prior
      approval of the Reinsurer.

      The phrase "claim-specific declaratory judgment expenses," as used in this
      Contract will mean all expenses incurred by the Company in connection with
      declaratory judgment actions brought to determine the Company's defense
      and/or indemnification obligations that are allocable to specific Policies
      and claims subject to this Contract. Declaratory judgment expenses will be
      deemed to have been incurred by the Company on the date of the original
      loss (if any) giving rise to the declaratory judgment action.

      All salvages, recoveries or payments recovered or received subsequent to
      loss settlements hereunder shall be applied as if recovered or received
      prior to the aforesaid settlement, and all necessary adjustments shall be
      made by the parties hereto.

      For purposes of this definition, the phrase "becomes liable to pay" shall
      mean the existence of a judgment, which the Company does not intend to
      appeal, or a release has been obtained by the Company, or the Company has
      accepted a proof of loss.

      Nothing in this clause shall be construed to mean that losses are not
      recoverable hereunder until the Company's Ultimate Net Loss has been
      ascertained.

B.    Policy or Policies

      "Policy" or "Policies," as used in this Contract, shall mean any binder,
      policy, or contract of insurance or reinsurance issued, accepted or held
      covered provisionally or otherwise, including any extended reporting
      periods, by or on behalf of the Company.

C.    Gross Net Earned Premium Income

      "Gross Net Earned Premium Income," as used in this Contract, shall mean
      gross earned premium income during the term of this Contract on business
      the subject of this Contract less earned premium income paid for
      reinsurances, recoveries under which would inure to the benefit of this
      Contract.

                                   ARTICLE IV

LOSS IN EXCESS OF POLICY LIMITS

This Contract shall protect the Company, within the limits hereof, in connection
with the Ultimate Net Loss in excess of the limit of its original Policy, such
loss in excess of the limit having been incurred because of failure by it to
settle within the Policy limit or by reason of alleged or actual negligence,
criminal act or fraud, or bad faith in rejecting an offer of settlement or in
the preparation of the defense or in the trial of any action against its insured
or reinsured or in the preparation or prosecution of an appeal consequent upon
such action.

For the purpose of this Article, the word "loss" shall mean any amounts for
which the Company would have been contractually liable to pay had it not been
for the limit of the original Policy. However, this Article shall not apply
where the loss has been incurred due to fraud by a member

                                                                   [WILLIS LOGO]

                                     Page 3

of the Board of Directors or a corporate officer of the Company acting
individually or collectively or in collusion with any individual or corporation
or any other organization or party involved in the presentation, defense or
settlement of any claim covered hereunder.

                                    ARTICLE V

EXTRA CONTRACTUAL OBLIGATIONS

This Contract shall protect the Company within the limits hereof, where the
Ultimate Net Loss includes any Extra Contractual Obligations. The term "Extra
Contractual Obligations" is defined as those liabilities not covered under any
other provision of this Contract and which arise from the handling of any claim
on business covered hereunder, such liabilities arising because of, but not
limited to, the following: failure by the Company to settle within the Policy
limit, or by reason of alleged or actual negligence, criminal act or fraud, or
bad faith in rejecting an offer of settlement or in the preparation of the
defense or in the trial of any action against its insured or reinsured or in the
preparation or prosecution of an appeal consequent upon such action.

The date on which any Extra Contractual Obligation is incurred by the Company
shall be deemed, in all circumstances, to be the date of the original disaster
and/or casualty.

However, this Article shall not apply where the loss has been incurred due to
fraud by a member of the Board of Directors or a corporate officer of the
Company acting individually or collectively or in collusion with any individual
or corporation or any other organization or party involved in the presentation,
defense or settlement of any claim covered hereunder.

                                   ARTICLE VI

TERRITORY

This Contract shall cover wherever the Company's original Policies cover.

                                   ARTICLE VII

EXCLUSIONS

This Contract does not cover and specifically excludes:

A.    Policies with per claim or per occurrence limits of $1,000,000 and less.

      When the Company writes a primary Policy and an umbrella Policy for the
      same Insured, and the sum of the per claim or per occurrence limits of the
      two Policies is greater than $1,000,000, this exclusion shall not apply to
      either Policy.

B.    Pools, Associations or Syndicates, except losses from Assigned Risk Plans
      or similar plans are not excluded.

C.    Nuclear Incident pursuant to the "Nuclear Incident Exclusion Clause -
      Liability - Reinsurance - U.S.A." attached hereto.

                                                                   [WILLIS LOGO]

<PAGE>

D.    Nuclear Incident pursuant to the "Nuclear Incident Exclusion Clause -
      Liability - Reinsurance - Canada" attached hereto.

E.    Liability of the Company arising by contract, operation of law or
      otherwise from its participation or membership, whether voluntary or
      involuntary, in any insolvency fund. "Insolvency fund" includes any
      guarantee fund, insolvency fund, plan, pool, association, fund or other
      arrangement, howsoever denominated, established or governed, which
      provides for any assessment of or payment or assumption by the Company of
      part or all of any claim, debt, charge, fee or other obligation of an
      insurer or its successors or assigns which has been declared by any
      competent authority to be insolvent or which is otherwise deemed unable to
      meet any claim, debt, charge, fee or other obligation in whole or in part.

F.    Financial Guarantee or Insolvency, when written as such.

      However, the liability of the Company under any bond covering losses due
      to negligence of any person or failure of any person to faithfully perform
      his duty or failure to account for and pay over money or other property in
      his custody shall not be considered Financial Guarantee or Insolvency.

      Notwithstanding the foregoing, no claim is to attach hereto in respect of
      any loss or losses arising as a result of:

      1.    The insolvency of any financial institution at which trust moneys

that retroactive extension of Policy terms or coverages made voluntarily by the
Company and not in response to court decisions (whether such court decision is
against the Company or other companies affording the same or similar coverages)

When so requested, the Company will afford the Reinsurer an opportunity to be
associated with the Company, at the expense of the Reinsurer, in the defense of
any claim or suit or proceeding involving this reinsurance, and the Company will

                                                                   [WILLIS LOGO]

                                   ARTICLE XV

CURRENCY

Whenever the word "Dollars" or the "$" sign appears in this Contract, they shall
be construed to mean United States Dollars and all transactions under this

                                  ARTICLE XVI

TAXES

In consideration of the terms under which this Contract is issued, the Company

                                  ARTICLE XVII

FEDERAL EXCISE TAX

(Applicable to those Reinsurers, excepting Underwriters at Lloyd's London and
other Reinsurers exempt from Federal Excise Tax, who are domiciled outside the
United States of America.)

The Reinsurer has agreed to allow, for the purpose of paying the Federal Excise
Tax, the applicable percentage of the premium payable hereon (as imposed under
Section 4371 of the Internal Revenue Code) to the extent such premium is subject
to the Federal Excise Tax.

In the event of any return of premium becoming due hereunder, the Reinsurer will
deduct the applicable percentage from the return premium payable hereon, and the
Company or its agent should take steps to recover the tax from the United States
Government.

                                                                   [WILLIS LOGO]

UNAUTHORIZED REINSURANCE

(Applies only to a Reinsurer who does not qualify for full credit with any
insurance regulatory authority having jurisdiction over the Company's reserves.)

As regards Policies or bonds issued by the Company coming within the scope of
this Contract, the Company agrees that when it shall file with the insurance
regulatory authority or set up on its books reserves for losses covered
hereunder which it shall be required by law to set up, it will forward to the
Reinsurer a statement showing the proportion of such reserves which is
applicable to the Reinsurer. The Reinsurer hereby agrees to fund such reserves
in respect of known outstanding losses that have been reported to the Reinsurer
and allocated loss adjustment expense relating thereto, losses and allocated
loss adjustment expense paid by the Company but not recovered from the
Reinsurer, plus reserves for losses incurred but not reported, as shown in the
statement prepared by the Company (hereinafter referred to as "Reinsurer's
Obligations") by funds withheld, cash advances or a Letter of Credit. The
Reinsurer shall have the option of determining the method of funding provided it
is acceptable to the insurance regulatory authorities having jurisdiction over
the Company's reserves.

When funding by a Letter of Credit, the Reinsurer agrees to apply for and secure
timely delivery to the Company of a clean, irrevocable and unconditional Letter
of Credit issued by a bank and containing provisions acceptable to the insurance
regulatory authorities having jurisdiction over the Company's reserves in an
amount equal to the Reinsurer's proportion of said reserves. Such Letter of
Credit shall be issued for a period of not less than one year and shall be
automatically extended for one year from its date of expiration or any future
expiration date unless 30 days (60 days where required by insurance regulatory
authorities) prior to any expiration date the issuing bank shall notify the
Company by certified or registered mail that the issuing bank elects not to
consider the Letter of Credit extended for any additional period.

The Reinsurer and Company agree that the Letters of Credit provided by the
Reinsurer pursuant to the provisions of this Contract may be drawn upon at any
time, notwithstanding any other provision of this Contract, and be utilized by
the Company or any successor, by operation of law, of the Company including,
without limitation, any liquidator, rehabilitator, receiver or conservator of
the Company for the following purposes, unless otherwise provided for in a
separate Trust Agreement:

(a)   to reimburse the Company for the Reinsurer's Obligations, the payment of
      which is due under the terms of this Contract and which has not been
      otherwise paid;

(b)   to make refund of any sum which is in excess of the actual amount required
      to pay the Reinsurer's Obligations under this Contract;

(c)   to fund an account with the Company for the Reinsurer's Obligations. Such
      cash deposit shall be held in an interest bearing account separate from
      the Company's other assets, and interest thereon not in excess of the
      prime rate shall accrue to the benefit of the Reinsurer;

(d)   to pay the Reinsurer's share of any other amounts the Company claims are
      due under this Contract.

                                                                   [WILLIS LOGO]

                                     Page 10

<PAGE>

In the event the amount drawn by the Company on any Letter of Credit is in
excess of the actual amount required for (a) or (c) or, in the case of (d), the
actual amount determined to be due, the Company shall promptly return to the
Reinsurer the excess amount so drawn. All of the foregoing shall be applied
without diminution because of insolvency on the part of the Company or the
Reinsurer.

The issuing bank shall have no responsibility whatsoever in connection with the
propriety of withdrawals made by the Company or the disposition of funds
withdrawn, except to ensure that withdrawals are made only upon the order of
properly authorized representatives of the Company.

At annual intervals or more frequently as agreed, but never more frequently than
quarterly, the Company shall prepare a specific statement of the Reinsurer's
Obligations, for the sole purpose of amending the Letter of Credit, in the
following manner:

(a)   If the statement shows that the Reinsurer's Obligations exceed the balance
      of credit as of the statement date, the Reinsurer shall, within 30 days
      after receipt of notice of such excess, secure delivery to the Company of
      an amendment to the Letter of Credit increasing the amount of credit by
      the amount of such difference.

(b)   If, however, the statement shows that the Reinsurer's Obligations are less
      than the balance of credit as of the statement date, the Company shall,
      within 30 days after receipt of written request from the Reinsurer,
      release such excess credit by agreeing to secure an amendment to the
      Letter of Credit reducing the amount of credit available by the amount of
      such excess credit.

                                   ARTICLE XIX

NET RETAINED LINES

This Contract applies only to that portion of any insurances or reinsurances
covered by this Contract, which the Company retains net for its own account and,
in calculating the amount of any loss hereunder and also in computing the amount
in excess of which this Contract attaches, only loss or losses in respect of
that portion of any insurances or reinsurances which the Company retains net for
its own account shall be included.

The Company reserves the right to maintain reinsurance agreement(s) in respect
of its net retention under this Contract, and recoveries under said
reinsurance(s) shall be entirely disregarded in determining the Ultimate Net
Loss hereunder.

The amount of the Reinsurer's liability hereunder in respect of any loss or
losses shall not be increased by reason of the inability of the Company to
collect from any other reinsurers, whether specific or general, any amounts
which may have become due from them whether such inability arises from the
insolvency of such other reinsurers or otherwise.

                                                                   [WILLIS LOGO]

THIRD PARTY RIGHTS

This Contract is solely between the Company and the Reinsurer, and in no
instance shall any other party have any rights under this Contract except as
expressly provided otherwise in the INSOLVENCY ARTICLE.

                                   ARTICLE XXI

SEVERABILITY

If any provision of this Contract should be invalid under applicable laws, the
latter shall control but only to the extent of the conflict without affecting
the remaining provisions of this Contract.

                                  ARTICLE XXII

GOVERNING LAW

This Contract shall be governed as to performance, administration and
interpretation by the laws of the State of Pennsylvania, exclusive of the rules
with respect to conflicts of law, except as to rules with respect to credit for
reinsurance, in which case the applicable rules of all states shall apply.

                                  ARTICLE XXIII

ACCESS TO RECORDS

The Company shall place at the disposal of the Reinsurer at all reasonable
times, and the Reinsurer shall have the right to inspect through its designated
representatives, all books, records and papers of the Company in connection with
any reinsurance hereunder or claims in connection herewith. Rights of access to
records shall survive the termination or expiration of this Contract.

                                  ARTICLE XXIV

INSOLVENCY

In the event of the insolvency of the Company, this reinsurance shall be payable
directly to the Company or to its liquidator, receiver, conservator or statutory
successor on the basis of the liability of the Company without diminution
because of the insolvency of the Company or because the liquidator, receiver,
conservator or statutory successor of the Company has failed to pay all or a
portion of any claim. It is agreed, however, that the liquidator, receiver,
conservator or statutory successor of the Company shall give written notice to
the Reinsurer of the pendency of a claim against the Company indicating the
Policy or bond reinsured, which claim would involve a possible liability on the
part of the Reinsurer, within a reasonable time after such claim is filed in the
conservation or liquidation proceeding or in the receivership and that, during
the

                                                                   [WILLIS LOGO]

                                     Page 12

<PAGE>

pendency of such claim, the Reinsurer may investigate such claim and interpose,
at its own expense, in the proceeding where such claim is to be adjudicated, any
defense or defenses that it may deem available to the Company or its liquidator,
receiver, conservator or statutory successor. The expense thus incurred by the
Reinsurer shall be chargeable, subject to the approval of the court, against the
Company as part of the expense of conservation or liquidation to the extent of a
pro rata share of the benefit, which may accrue to the Company solely as a
result of the defense undertaken by the Reinsurer.

Where two or more reinsurers are involved in the same claim and a majority in
interest elect to interpose defense to such claim, the expense shall be
apportioned in accordance with the terms of this Contract as though such expense
had been incurred by the insolvent Company.

In the event of the insolvency of the Company, the reinsurance under this
Contract shall be payable directly by the Reinsurer to the Company or to its
liquidator, receiver, conservator or statutory successor, except as provided by
Section 4118(a) of the New York Insurance Law or except (a) where this Contract
specifically provides another payee of such reinsurance in the event of the
insolvency of the Company or (b) where the Reinsurer with the consent of the
direct insured or insureds has assumed such Policy obligations of the Company as
direct obligations of the Reinsurer to the payees under such Policies and in
substitution for the obligations of the Company to such payees.

Should the Company go into liquidation or should a receiver be appointed, all
amounts due either Company or Reinsurer under this or any other agreement,
whether by reason of premium, losses or otherwise under this Contract, shall be
subject to the right of offset at any time and from time to time and, upon the
exercise of the same, only the net balance shall be due.

In the event of the insolvency of any company or companies included in the
designation of "Company," this clause will apply only to the insolvent company
or companies.

                                   ARTICLE XXV

ARBITRATION

As a condition precedent to any right of action hereunder, any irreconcilable
dispute between the parties to this Contract will be submitted for decision to a
board of arbitration composed of two arbitrators and an umpire meeting in Bala
Cynwyd, Pennsylvania.

Arbitration shall be initiated by the delivery of a written notice of demand for
arbitration by one party to the other within a reasonable time after the dispute
has arisen.

The members of the board of arbitration shall be active or former, disinterested
officials of insurance or reinsurance companies or Underwriters at Lloyd's,
London, not under the control or management of either party to this Contract.
Each party shall appoint its arbitrator, and the two arbitrators shall choose an
umpire before instituting the hearing. If the respondent fails to appoint its
arbitrator within 4 weeks after being requested to do so by the claimant, the
latter shall also appoint the second arbitrator.

If the two arbitrators are unable to agree upon the umpire within 30 days of
their appointment, the umpire shall be selected by a judge of any court of
competent jurisdiction.

                                                                   [WILLIS LOGO]

                                     Page 13

<PAGE>

The claimant shall submit its initial brief within 45 days from appointment of
the umpire. The respondent shall submit its brief within 45 days thereafter, and
the claimant may submit a reply brief within 30 days after filing of the
respondent's brief.

The board shall make its decision with regard to the custom and usage of the
insurance and reinsurance business. The board shall issue its decision in
writing based upon a hearing in which evidence may be introduced without
following strict rules of evidence but in which cross-examination and rebuttal
shall be allowed. The board shall make its decision within 60 days following the
termination of the hearings unless the parties consent to an extension. The
majority decision of the board shall be final and binding upon all parties to
the proceeding. Judgment may be entered upon the award of the board in any court
having jurisdiction.

If more than one reinsurer is involved in the same dispute, all such reinsurers
shall constitute and act as one party for purposes of this clause, and
communications shall be made by the Company to each of the reinsurers
constituting the one party provided, however, that nothing therein shall impair
the rights of such reinsurers to assert several rather than joint defenses or
claims, nor be construed as changing the liability of the reinsurers under the
terms of this Contract from several to joint.

Each party shall bear the expense of its own arbitrator and shall jointly and
equally bear with the other party the expense of the umpire. The remaining costs
of the arbitration proceedings shall be allocated by the board.

                                  ARTICLE XXVI

CONFIDENTIALITY

The Reinsurer, except with the express prior written consent of the Company,
shall not directly or indirectly communicate, disclose or divulge to any third
party, any knowledge or information that may be acquired either directly or
indirectly as a result of the inspection of the Company's books, records and
papers. The restrictions, as outlined in this Article, shall not apply to
communication or disclosures that the Reinsurer is required to make to its
statutory auditors, parent company, retrocessionaires, potential
retrocessionaires, legal counsel, arbitrators involved in any arbitration
procedures under this Contract or disclosures required upon subpoena or other
duly-issued order of a court or other governmental agency or regulatory
authority.

SERVICE OF SUIT

(This Article only applies to reinsurers domiciled outside of the United States
and/or unauthorized in any state, territory, or district of the United States
having jurisdiction over the Company).

It is agreed that, in the event of the failure of the Reinsurer hereon to pay
any amount claimed to be due hereunder, the Reinsurer hereon, at the request of
the Company, will submit to the jurisdiction of a court of competent
jurisdiction within the United States. Nothing in this Article constitutes or
should be understood to constitute a waiver of the Reinsurer's rights to
commence

                                                                   [WILLIS LOGO]

an action in any court of competent jurisdiction in the United States, to remove
an action to a United States District Court or to seek a transfer of a case to
another court as permitted by the laws of the United States or of any state in
the United States.

It is further agreed that service of process in such suit may be made upon
Mendes and Mount, 750 Seventh Avenue, New York, New York 10019, and that in any
suit instituted the Reinsurer will abide by the final decision of such court or

      Reinsurer of any Declaratory Judgment Expenses subject to this Agreement.

E.    All recoveries, salvages or payments recovered or received subsequent to a

ARTICLE VIII - LOSS IN EXCESS OF POLICY LIMITS

A.    "Loss in Excess of Policy Limits" is defined as loss in excess of the
      limit of the original Policy, such loss in excess of the limit having been
      incurred because of failure by the Company to settle within the Policy
      limit or by reason of alleged or actual negligence, fraud or bad faith in
      rejecting an offer of settlement or in the preparation of the defense or
      in the trial of any action against its insured or in the preparation or
      prosecution of an appeal consequent upon such action.

B.    However, this Article shall not apply where the loss has been incurred due
      to fraud by a member of the Board of Directors or a corporate officer of
      the Company acting individually or collectively or in collusion with any
      individual or corporation or any other organization or party involved in
      the presentation, defense or settlement of any claim covered hereunder.

C.    For the purposes of this Article, the word "loss" shall mean any amounts
      which the Company would have been contractually liable to pay had it not
      been for the limit of the original Policy.

D.    With respect to coverage provided under this Article, recoveries from any
      insurance or reinsurance other than this Agreement shall be deducted to
      arrive at the amount of the Company's Ultimate Net Loss.

ARTICLE IX - EXTRA CONTRACTUAL OBLIGATIONS

A.    "Extra Contractual Obligations" are defined as those liabilities not
      covered under any other provision of this Agreement and which arise from
      the handling of any claim on business covered hereunder, such liabilities
      arising because of, but not limited to, the following: failure by the
      Company to settle within the Policy limit, or by reason of alleged or

      Losses which, together with available financial assistance under the Act
      and the Company retentions and/or deductibles hereunder, exceed the
      Company's Insured Losses. In such event, the Reinsurer's proportional
      share of all such excess recovery (hereafter "Reinsurer's Excess Share")
      shall inure to the benefit of the Reinsurer. All excess recovery described
      in this Paragraph shall be allocated to the Reinsurer and the Company in
      proportion to the respective liability of each for Insured Losses, net of
      federal assistance under the Act, salvage, subrogation and other similar
      recoveries, as applicable.

F.    In the event of a Reinsurer's Excess Share, the Company shall:

      1.    Promptly pay the Reinsurer's Excess Share to the Reinsurer; or

      2.    Upon request of the Reinsurer at any time and at the Reinsurer's
            sole discretion, instead assign to the Reinsurer its rights to
            recover directly from the federal government any portion of
            Reinsurer's Excess Share not already paid to the Reinsurer. The
            Company shall cooperate with and assist the Reinsurer, at its own
            expense, to the extent reasonably necessary for the Reinsurer to
            exercise those rights. If the Reinsurer is unable, for any reason,
            to exercise any right assigned to it by the Company pursuant to this
            Article, the Company shall pay the Reinsurer's Excess Share to the
            Reinsurer as if no assignment had taken place to the extent that the
            Company has not been deemed to have forfeited the right to financial
            assistance under the Act by virtue of the attempted assignment.

G.    In the event of an Insured Loss, the Company shall provide the Reinsurer
      with a monthly report detailing claim settlement activities and financial
      assistance under the Act. Calculations for each Program Year shall
      continue to be made until the settlement of all Insured Losses covered
      hereunder.

ARTICLE XVIII - ACCESS TO RECORDS

The Reinsurer or its duly authorized representatives shall have the right to
examine, at the offices of the Company at a reasonable time, during the currency
of this Agreement or anytime thereafter, all books and records of the Company
relating to business which is the subject of this Agreement.

<PAGE>

ARTICLE XIX - TAXES

The Company shall be liable for all taxes on premiums paid to the Reinsurer
under this Agreement, except income or profit taxes of the Reinsurer, and shall
indemnify and hold the Reinsurer harmless for any such taxes which the Reinsurer
may become obligated to pay to any local, state or federal taxing authority.

ARTICLE XX - CURRENCY

Wherever the word "dollars" or the "$" symbol is used in this Agreement, it
shall mean dollars of the United States of America, excepting in those cases
where the Policy is issued by the Company in Canadian dollars, in which case it
shall mean dollars of Canada. In the event the Company is involved in a loss
requiring payment in United States and Canadian currency, the Company's
retention and the limit of liability of the Reinsurer shall be apportioned
between the two currencies in the same proportion as the amount of net loss in
each currency bears to the total amount of net loss paid by the Company. For the
purposes of this Agreement, where the Company receives premiums or pays losses
in currencies other than United States or Canadian currency, such premiums and
losses shall be converted into United States dollars at the actual rates of
exchange at which the premiums and losses are entered in the Company's books.

ARTICLE XXI - OFFSET

Each party to this Agreement together with their successors or assigns shall
have and may exercise, at any time, the right to offset any balance or balances
due the other (or, if more than one, any other). Such offset may include
balances due under this Agreement and any other agreements heretofore or
hereafter entered into between the parties regardless of whether such balances
arise from premiums, losses or otherwise, and regardless of capacity of any
party, whether as assuming insurer and/or ceding insurer, under the various
agreements involved, provided however, that in the event of insolvency of a
party hereto, offsets shall only be allowed in accordance with the provisions of
Section 7427 of the Insurance Law of the State of New York to the extent such
statute or any other applicable law, statute or regulation governing such offset
shall apply.

ARTICLE XXII - ERRORS OR OMISSIONS

Errors or omissions of an administrative nature on the part of the Company shall
not invalidate the reinsurance under this Agreement, provided such errors or
omissions are corrected promptly after discovery

<PAGE>

thereof; but the liability of the Reinsurer under this Agreement or any
exhibits, addenda, or endorsements attached hereto shall in no event exceed the
limits specified herein nor be extended to cover any risks, perils, lines of
business or classes of insurance generally or specifically excluded herein.

ARTICLE XXIII - DISPUTE RESOLUTION

Part I - Choice Of Law And Forum

Any dispute arising under this Agreement shall be resolved in the State of
Pennsylvania, and the laws of the State of Pennsylvania shall govern the
interpretation and application of this Agreement.

Part II - Mediation

If a dispute between the Company and the Reinsurer, arising out of the
provisions of this Agreement or concerning its interpretation or validity and
whether arising before or after termination of this Agreement has not been
settled through negotiation, both parties agree to try in good faith to settle
such dispute by nonbinding mediation, before resorting to arbitration.

Part III - Arbitration

A.    Resolution of Disputes - As a condition precedent to any right of action
      arising hereunder, any dispute not resolved by mediation between the
      Company and the Reinsurer arising out of the provisions of this Agreement
      or concerning its interpretation or validity, whether arising before or
      after termination of this Agreement, shall be submitted to arbitration in
      the manner hereinafter set forth.

B.    Composition of Panel - Unless the parties agree upon a single arbitrator
      within 15 days after the receipt of a notice of intention to arbitrate,
      all disputes shall be submitted to an arbitration panel composed of two
      arbitrators and an umpire chosen in accordance with Paragraph C. hereof.

C.    Appointment of Arbitrators - The members of the arbitration panel shall be
      chosen from persons knowledgeable in the insurance and reinsurance
      business. Unless a single arbitrator is agreed upon, the party requesting
      arbitration (hereinafter referred to as the "claimant") shall appoint an
      arbitrator and give written notice thereof by certified mail, to the other
      party (hereinafter referred to as the "respondent") together with its
      notice of intention to arbitrate. Within 30 days after receiving such
      notice, the respondent shall also appoint an arbitrator and notify the
      claimant thereof by certified mail. Before instituting a hearing, the two
      arbitrators so appointed shall choose an umpire. If, within 20 days after
      the appointment of the arbitrator chosen by the respondent, the

<PAGE>
      two arbitrators fail to agree upon the appointment of an umpire, each of
      them shall nominate three individuals to serve as umpire, of whom the
      other shall decline two and the umpire shall be chosen from the remaining
      two by drawing lots. The name of the individual first drawn shall be the
      umpire.

D.    Failure of Party to Appoint an Arbitrator - If the respondent fails to
      appoint an arbitrator within 30 days after receiving a notice of intention
      to arbitrate, the claimant's arbitrator shall appoint an arbitrator on
      behalf of the respondent, such arbitrator shall then, together with the
      claimant's arbitrator, choose an umpire as provided in Paragraph C. of
      Part III of this Article.

E.    Submission of Dispute to Panel - Unless otherwise extended by the
      arbitration panel or agreed to by the parties, each party shall submit its
      case to the panel within 30 days after the selection of the umpire.

F.    Procedure Governing Arbitration - All proceedings before the panel shall
      be informal and the panel shall not be bound by the formal rules of
      evidence. The panel shall have the power to fix all procedural rules
      relating to the arbitration proceeding. In reaching any decision, the
      panel shall give due consideration to the customs and usages of the
      insurance and reinsurance business.

G.    Arbitration Award - The arbitration panel shall render its decision within
      60 days after termination of the proceeding, which decision shall be in
      writing, stating the reasons therefor. The decision of the majority of the
      panel shall be final and binding on the parties to the proceeding.

H.    Cost of Arbitration - Unless otherwise allocated by the panel, each party
      shall bear the expense of its own arbitrator and shall jointly and equally
      bear with the other parties the expense of the umpire and the arbitration.

ARTICLE XXIV- INSOLVENCY

A.    In the event of insolvency of the Company, the reinsurance provided by
      this Agreement shall be payable by the Reinsurer on the basis of the
      liability of the Company as respects Policies covered hereunder, without
      diminution because of such insolvency, directly to the Company or its
      liquidator, receiver, conservator or statutory successor except as
      provided in Sections 4118(a)(1)(A) and 1114(c) of the New York Insurance
      Law.

<PAGE>

B.    The Reinsurer shall be given written notice of the pendency of each claim
      or loss which may involve the reinsurance provided by this Agreement
      within a reasonable time after such claim or loss is filed in the
      insolvency proceedings. The Reinsurer shall have the right to investigate
      each such claim or loss and interpose, at its own expense, in the
      proceedings where the claim or loss is to be adjudicated, any defense
      which it may deem available to the Company, its liquidator, receiver,
      conservator or statutory successor. The expense thus incurred by the
      Reinsurer shall be chargeable, subject to court approval, against the
      insolvent Company as part of the expense of liquidation to the extent of a
      proportionate share of the benefit which may accrue to the Company solely
      as a result of the defense undertaken by the Reinsurer.

C.    In addition to the offset provisions set forth in Article XXI- Offset, any
      debts or credits, liquidated or unliquidated, in favor of or against
      either party on the date of the receivership or liquidation order (except
      where the obligation was purchased by or transferred to be used as an
      offset) are deemed mutual debts or credits and shall be set off with the
      balance only to be allowed or paid. Although such claim on the part of
      either party against the other may be unliquidated or undetermined in
      amount on the date of the entry of the receivership or liquidation order,
      such claim will be regarded as being in existence as of such date and any
      claims then in existence and held by the other party may be offset against
      it.

D.    Nothing contained in this Article is intended to change the relationship
      or status of the parties to this Agreement or to enlarge upon the rights
      or obligations of either party hereunder except as provided herein.

ARTICLE XXV - SPECIAL TERMINATION

A.    Notwithstanding the termination provisions set forth in Article
      II-Effective Date and Termination, this Agreement shall be:

      1.    Terminated automatically and simultaneously upon the happening of
            any of the following events:

            a.    Entry of an order of liquidation, rehabilitation, receivership
                  or conservatorship with respect to the Company or the
                  Reinsurer by any court or regulatory authority;

            b.    Assignment of this Agreement by either party;

            c.    General reinsurance of any portion of the Company's business
                  it retains net for its own account, as determined under the
                  provisions of this Agreement without prior consent of the
                  Reinsurer.

<PAGE>

      2.    Terminated by either party giving not less than 30 days prior
            written notice to the other party upon the happening of the
            following event:

                  Any transfer of control of either party by change in ownership
                  or otherwise.

      3.    Terminated by the Reinsurer by giving not less than 30 days prior
            written notice to the Company upon the happening of the following
            event:

                  Failure of the Company to remit premiums in accordance with
                  the provisions set forth in this Agreement.

      4.    Terminated in accordance with the provisions set forth in this
            Paragraph, upon the discovery of the following event:

                  A reduction of 50% or more of the Company's policyholders
                  surplus during any calendar year. Such reduction shall be
                  determined by calculating the difference between the Company's
                  prior year annual statement and each subsequent quarterly
                  statutory statement within such current calendar year.

            Asrespects the event set forth in this Paragraph A.4., the Company
            shall be obligated to notify the Reinsurer in writing within 30 days
            after the filing of its quarterly statement. Upon receipt of such
            notification the Reinsurer shall have the right to terminate this
            Agreement, by giving not less than 30 days notice of its intention
            to do so.

B.    Any notice of termination pursuant to the provisions set forth in
      Paragraphs A.2., A.3. and A.4. above shall be sent by certified mail,

      party's receipt of the notice of termination.

C.    In the event of termination, as provided under the provisions of this
      Article, the Reinsurer shall not be liable for losses occurring subsequent
      to the date of termination.
