ITEM 2.   ACQUISITION OR DISPOSITION OF ASSETS.

       Effective April 1, 1998, Zenith Insurance Company, a wholly owned 
subsidiary of the Registrant ("Zenith Insurance"), closed its previously 
announced transaction with RISCORP, Inc. and certain of its subsidiaries 
(collectively, "RISCORP"), pursuant to which Zenith Insurance has acquired 
substantially all of the assets and assumed certain liabilities of RISCORP 
related to its workers' compensation business, including RISCORP's existing 
in-force insurance business as well as the right to all new and renewal 
policies. Zenith Insurance also acquired RISCORP's "First Call"(sm) managed 
care workers' compensation system.  After the closing, RISCORP will no longer 
engage in the workers' compensation or managed care businesses.  The assets 
acquired by Zenith Insurance consist of investments, receivables, reinsurance 
recoverables, property, plant and equipment, office leases, certain trade 
names and other assets.  Real estate acquired by Zenith Insurance was 
previously used by RISCORP for its workers' compensation operations and will 
be used by Zenith Insurance for its southeast workers' compensation 
operations.

       The final purchase price, to be paid in cash, will be the difference 
between the book value of the assets purchased and the book value of the 
liabilities assumed by Zenith Insurance as of April 1, 1998.  The final 
purchase price is subject to audit and a dispute resolution process, and 
cannot be determined at this time. At the closing, Zenith Insurance paid the 
minimum cash purchase price of $35 million and in addition repaid $15 million 
of indebtedness of RISCORP, Inc. Zenith Insurance will pay any additional 
purchase price from internal funds.

       As part of the closing, Zenith Insurance entered into Assumption and 
Indemnity Reinsurance Agreements with each of the three insurance 
subsidiaries of RISCORP, Inc.

                    ASSUMPTION AND INDEMNITY REINSURANCE AGREEMENT

          THIS ASSUMPTION AND INDEMNITY REINSURANCE AGREEMENT (this
"Agreement"), dated as of 12:01 a.m. New York City Time on April 1, 1998 (the
"Effective Date"), is made by and between ZENITH INSURANCE COMPANY, a stock
insurance company organized under the laws of the State of California
("Zenith"), and RISCORP NATIONAL INSURANCE COMPANY, a stock insurance company
organized under the laws of the State of Missouri (the "Company").

          WHEREAS, Zenith and the Company have entered into the Purchase
Agreement (as defined below); and

          WHEREAS, the Purchase Agreement provided for Zenith and the Company to
enter into an indemnity reinsurance agreement; 

          WHEREAS, the parties have agreed to amend the Purchase Agreement to
provide for Zenith and the Company to enter into an assumption reinsurance
agreement; 

          WHEREAS, Zenith and the Company are entering into this Agreement
pursuant to the Purchase Agreement, as so amended; 

          WHEREAS, the Company has agreed to cede to Zenith, and Zenith has
agreed to assume certain liabilities and obligations of the Company under the
Insurance Contracts (as defined in the Purchase Agreement).

          NOW, THEREFORE, in consideration of the mutual covenants and promises
and upon the terms and conditions set forth herein, the parties hereto agree as
follows:


                                     ARTICLE I

                                    DEFINITIONS

          Section 1.1.  DEFINITIONS.  Capitalized terms used herein and not
otherwise defined in this Agreement shall have the meanings given to them in the
Purchase Agreement.  As used in this Agreement, the following terms shall have
the following meanings:

          "CLAIMANT" means any claimant under any Insurance Contract who (a) has
an open claim on the Effective Date, or (b) files a claim after the Effective
Date.  

          "EFFECTIVE DATE" means the date specified in the first paragraph
hereof.

          "INSURANCE CONTRACTS" shall mean those Insurance Contracts (as defined
in the Purchase Agreement) issued by the Company.


<PAGE>

          "INSURANCE LIABILITIES" shall mean those Insurance Liabilities (as
defined in the Purchase Agreement) arising under or in connection with the
Insurance Contracts.

          "NOVATED POLICIES" means those Insurance Contracts for which: (a) the
Company or Zenith has received a written acceptance by the Policyholder of the
transfer and assumption under this Agreement; or (b) with respect to any
Insurance Contract that was issued or issued for delivery in a state where
written acceptance by the Policyholder is not required by law or the appropriate
regulatory authority to effect an assumption and novation, (i) the Policyholder
is deemed to have accepted the transfer and assumption under this Agreement by
paying premiums directly to Zenith or taking such other action as may be
recognized under applicable state law as evidence of the Policyholder's
acceptance of the transfer and assumption, or (ii) the Policyholder has,
following the mailing to the Policyholder of such notices as may be prescribed
by applicable state law, neither accepted nor rejected the transfer and
assumption within a timeframe under which applicable state law or appropriate
regulatory authority permits the policyholder to be deemed to have accepted the
transfer and assumption.  Any claim made by any Claimant under an Insurance
Contract which expired prior to the Effective Date shall, subject to the last
sentence of this paragraph, be deemed to be a claim under a Novated Policy.  If
an Insurance Contract defined herein as a Novated Policy is determined by law or
an appropriate regulatory authority, by judicial decision or otherwise to be not
novated, such Insurance Contract shall for all purposes of this Agreement be
deemed retroactive to the Effective Date to be a Quota Share Policy.  

          "POLICYHOLDER" means each holder of an Insurance Contract that is in
force on the Effective Date.

          "PURCHASE AGREEMENT" means the Asset Purchase Agreement, dated as of
June 17, 1997, as amended, among Zenith, the Company, RISCORP Insurance Company,
RISCORP Property Casualty Insurance Company, RISCORP, Inc., RISCORP of Florida,
Inc., RISCORP Management Services, Inc., RISCORP Managed Care Services, Inc.,
RISCORP Insurance Services, Inc., CompSource, Inc., RISCORP of Illinois, Inc.,
Independent Association Administrators Incorporated, RISCORP Real Estate
Holdings, Inc., RISCORP Acquisition, Inc., RISCORP West, Inc., RISCORP Services,
Inc., RISCORP Staffing Solutions Holdings, Inc., RISCORP Staffing Solutions,
Inc. I and RISCORP Staffing Solutions, Inc. II.

          "QUOTA SHARE POLICIES" shall have the meaning set forth in Section 2.3
hereof.

                                  ARTICLE II

                              BUSINESS REINSURED

          Section 2.1.  BUSINESS REINSURED.  Subject to all of the terms and
conditions contained herein, the Company hereby cedes to Zenith, and Zenith
hereby assumes as reinsurance from the Company, all of the rights and
obligations of the Company under each of the Insurance Contracts.

          Section 2.2.  NOVATED POLICIES.  Zenith shall be the successor to the
Company under the Novated Policies that it assumes as if the Novated Policies
were direct obligations originally issued by Zenith.  Zenith shall be
substituted in the place and stead of the Company so as to effect a novation of
the respective Insurance Contracts and release the Company from any and all
rights and obligations thereunder.  Each insured under a Novated Policy shall
disregard the Company as a party thereto and treat Zenith as if it had been
originally obligated thereunder except as otherwise provided herein.  The
insureds shall file claims arising under the Novated Policies on or after the
effective date of such novation directly with Zenith.  The insureds under the
Novated Policies shall also have a right to assert claims related to such
Novated Policies directly against Zenith and Zenith hereby consents to be
subject to such claims by any insured under the Novated Policy; PROVIDED,
HOWEVER, that the rights of any insured under any Insurance Contract shall be
limited to and consist of those rights set forth in such Insurance Contract
(including any rider or endorsement thereto), and no insured shall have the
right to receive any greater amount under any Insurance Contract than such
insured would have had in the absence of this Agreement (except that in
assessing such right no effect shall be given to any bankruptcy, liquidation,
insolvency, reorganization or moratorium of the Company, or the effect of laws
or legal procedures affecting enforcement of creditors' rights against the
Company generally).  Payments made to insureds in discharge of obligations on
Novated Policies to provide direct coverage to insureds will diminish any
obligation in respect to those Novated Policies which Zenith may have to the
estate of the Company if it shall be in receivership, liquidation or
rehabilitation proceedings.  

          Section 2.3.  QUOTA SHARE POLICIES.  To the extent Zenith has not for
any reason assumed by novation any Insurance Contracts or Insurance Liabilities,
Zenith shall accept and reinsure, on a quota share basis, 100% of Insurance
Liabilities under such Insurance Contracts (the "Quota Share Policies"), in
accordance with the terms and conditions of this Agreement, and hereby agrees to
pay directly, on behalf of the Company, any claims or losses reinsured under
this Agreement which arise under such Quota Share Policies; PROVIDED, HOWEVER,
that the insureds under such Quota Share Policies shall not have the right to
assert claims related to such Quota Share Policies directly against Zenith.  A
payment made to an insured in discharge of bligations of RISCORP to provide
direct coverage to the insured

                                      -3-

<PAGE>

will diminish the obligation in respect thereof which Zenith may have to the 
estate of the Company if it shall be in receivership, liquidation or 
rehabilitation proceedings. 

          Section 2.4.  TERMS; CONDITIONS.  All Insurance Liabilities for which
Zenith shall assume liability hereunder, either as Novated Policies or Quota
Share Policies, are subject in all respects to the same written terms,
conditions, waivers, modifications, alterations and cancellations as the
Insurance Contracts.  Zenith accepts and assumes the Insurance Liabilities
subject to all defenses, setoffs and counterclaims to which the Company would be
entitled with respect to the Insurance Contracts.  The parties agree that no
such defenses, setoffs or counterclaims are waived under this Agreement and that
as of the Effective Date, Zenith shall be fully subrogated to all such defenses,
setoffs and counterclaims and be entitled to the full benefits thereof.


                                 ARTICLE III

                           ASSUMPTION CERTIFICATES

          Section 3.1.  NOTICE OF TRANSFER AND CERTIFICATE OF ASSUMPTION. (a) 
Zenith, with the cooperation and assistance of the Company, shall prepare for
mailing to every Policyholder a Notice of Transfer and Certificate of
Assumption, including a form for rejection or acceptance and a self-addressed
return envelope, substantially in the form attached hereto as EXHIBIT A
(collectively, the "Policyholder Notices"), subject to changes required by state
law or required by any state insurance regulator as a condition for approval of
the mailing of such Policyholder Notices to Policyholders.  The Company shall
cooperate and assist Zenith in the preparation and mailing of the Policyholder
Notices as provided herein.  Zenith shall mail Policyholder Notices by certified
mail, return receipt requested, to the Policyholders located in a particular
state within thirty days of receipt of all regulatory approvals necessary for
such mailing.

     (b)  Zenith, with the cooperation and assistance of the Company, shall
prepare for mailing and mail, within thirty days of receipt of all regulatory
approvals necessary for such mailing, to each holder of an Insurance Contract
which expired without renewal during the two year period immediately prececeding
the Effective Date a Notice of Transfer and Assumption substantially in the form
attached hereto as EXHIBIT B (collectively, the "Expired Policy Notices"),
subject to changes required by state law or required by any state insurance
regulator as a condition for approval of the mailing of such Expired Policy
Notices to said holders of Insurance Contracts and Claimants.  

     (c)  Zenith, with the cooperation and assistance of the Company, shall
prepare for mailing and mail, within thirty days

                                     -4-

<PAGE>

of the Effective Date, to each Claimant who has an open claim on the 
Effective Date, a Notice substantially in the form attached hereto as EXHIBIT 
C (collectively, the "Claimant Notices"), subject to changes required by 
state law or required by any state insurance regulator as a condition for 
approval of the mailing of such Claimant Notices to said holders of Insurance 
Contracts and Claimants.  In addition, Zenith, with the cooperation and 
assistance of the Company, shall prepare and mail a Claimant Notice to each 
Claimant who is not a Policyholder (as defined herein), but who, after the 
Effective Date, files a claim under any Insurance Contract.

          Section 3.2.  EFFECT OF NOTICE.  A Policyholder shall be deemed to
have accepted the transfer and assumption under this Agreement(1) upon receipt
by Zenith of the Policyholder's written acceptance of the transfer and
assumption, or (2) with respect to any Insurance Contract issued or issued for
delivery in a state where written acceptance by the Policyholder is not required
by the appropriate regulatory authority to effect an assumption and novation,
upon taking such action, or failing to take any action following the mailing of
the Policyholder Notice, as specified in Schedule 3.2. attached hereto.      


                                ARTICLE IV

                          POLICY ADMINISTRATION

          Section 4.1.  POLICY ADMINISTRATION BY ZENITH.  The Company grants to
Zenith authority in all matters relating to the administration of the Insurance
Contracts assumed by Zenith to the extent such authority may be granted pursuant
to applicable law and agrees to cooperate fully with Zenith in the transfer of
such administration.  Zenith agrees, at its expense, to be responsible for such
administration.  In order to assist and to evidence more fully the substitution
of Zenith in the place and stead of the Company, the Company hereby nominates,
constitutes and appoints Zenith as its attorney-in-fact with respect to the
rights, duties, privileges and obligations of the Company in and to the
Insurance Contracts assumed by Zenith, with full power and authority to act in
the name, place and stead of the Company with respect to such Insurance
Contracts including, without limitation, the power without reservation, to
service all such Insurance Contracts, to adjust, to defend, to settle and to pay
all claims, to recover salvage and subrogation for any losses incurred and to

                      ASSIGNMENT OF CEDED REINSURANCE AGREEMENTS

          Section 7.1.  ASSIGNMENT.  (a)  As of the Effective Date, the Company
shall transfer, set over, assign and convey to Zenith all of its right, title
and interest in any amount held by or due from the assuming reinsurers under the
reinsurance agreements listed in SCHEDULE 7.1-A ("Schedule 7.1-A Reinsurance"),
including (i) amounts held by or which may become due from the assuming
reinsurers thereunder for losses or loss adjustment expenses on Insurance
Contracts for which the Reinsurer has assumed liability or for losses paid by
the Company prior to the Effective Date, and (ii) letters of credit, trust funds
and other security mechanisms outstanding for the benefit of the Company
pursuant to the terms of any of the Schedule 7.1-A Reinsurance.  The Company
hereby authorizes Zenith, as of the Effective Date, to prepare and submit, on
the Company's behalf and in the Company's name, all statements and reports
required of the Company under the Schedule 7.1-A Reinsurance, and further
authorizes Zenith to take all other actions required of the Company under the
Schedule 7.1-A Reinsurance or otherwise permitted thereunder, and Zenith agrees
to prepare and submit such reports and take all such actions, except that Zenith
shall not undertake to pay on behalf of the Company, and shall not be obligated
hereunder to pay, any amount due to the reinsurers under the Schedule 7.1-A
Reinsurance unless the Company's obligation to pay such amount shall have been
accrued as a liability on the Final Business Balance Sheet.  

          (b)  As of the Effective Date, the Reinsurer shall be substituted for
and succeed to all of the rights and liabilities of the Company, under the
reinsurance agreements listed in SCHEDULE 7.1-B (the "Schedule 7.1-B
Reinsurance" and, together with the Schedule 7.1-A Reinsurance, the "Ceded
Reinsurance") and shall be recognized for all purposes as the "Company"
thereunder in substitution for the Company.  The Company shall transfer, set
over, assign and convey to Zenith all of its rights and obligations of any
nature whatsoever under the Schedule 7.1-B Reinsurance, including (i) amounts
held by or which may become due from assuming reinsurers with respect to any
reinsurance ceded by the Company to the reinsurer thereunder, and (ii) letters
of credit, trust funds and other security mechanisms outstanding for the benefit
of the Company pursuant to the terms of any of the Ceded Reinsurance.  Zenith
shall accept such conveyance, transfer and assignment of the Company's rights
under the Schedule 7.1-B Reinsurance and assumes all of the Company's
obligations under the Schedule 7.1-B Reinsurance existing on or arising after
the Effective Date.  The assignment and assumption of the Schedule 7.1-B
Reinsurance effected by this Section 7.1 shall be effective only if such
assignment (i) is permitted under the terms of such Schedule 7.1-B Reinsurance
or as otherwise consented to by the reinsurer thereunder, and (ii) shall
preserve fully the obligations of the reinsurers thereunder in respect of the
Insurance Contracts.  If the Company's rights and obligations

                                     -7-

<PAGE>

under any such Schedule 7.1-B Reinsurance are not assigned to and assumed by 
Zenith, (i) after the Effective Date, Zenith shall be responsible for the 
payment of all premiums and other considerations required to be paid by the 
Company in respect of any of the Schedule 7.1-B Reinsurance, (ii) all 
reinsurance recoveries attributable to any of the Schedule 7.1-B Reinsurance 
are assigned and shall accrue to the benefit of Zenith hereunder by operation 
of this Section 7.1 and shall, upon receipt thereof by the Company, be paid 
promptly thereby to Zenith upon and in accordance with its direction, and 
(iii) such assignment shall be effective at such time as the assignment may 
be effected while preserving fully the obligations of the reinsurer under the 
respective Schedule 7.1-B Reinsurance.  

          (c)  The Company shall reasonably cooperate with Zenith in causing
reinsurers under the Ceded Reinsurance to pay reinsurance recoveries to Zenith
after the Effective Date.

          Section 7.2.  CEDED REINSURANCE COLLATERAL.  To the extent necessary
to effect any transfer or assignment pursuant to this Section 7.1 of any assumed
reinsurance, the Company hereby appoints Zenith as attorney-in-fact for the
Company to act for and on behalf of it with respect to letters of credit, trust
funds and other security mechanisms outstanding for the benefit of the Company
pursuant to the terms of any of the Ceded Reinsurance, and the Company shall
execute and deliver to Zenith such additional instruments as Zenith may
reasonably request to give effect to such appointment as attorney-in-fact, and
to provide appropriate evidence that the Company has assigned to Zenith all of
its rights under the Ceded Reinsurance with respect to any such letters of
credit, trust funds or other accounting mechanism.  Zenith shall use its
reasonable best efforts to the extent deemed reasonably necessary by Zenith, to
cause the reinsurers under the Ceded Reinsurance to provide replacement letters
of credit, trust funds or other security mechanisms, as applicable, naming
Zenith as the beneficiary thereof in amounts and with terms substantially
similar to those currently provided by such reinsurers for the benefit of the
Company.

                               INDEMNIFICATION

defense, setoff or counterclaim with respect to, or amend, commute or terminate,
any Insurance Contract or Ceded Reinsurance without the prior written consent of
Zenith, except in accordance with the provisions of the indemnities referred to
in the following sentence.  The Company's sole and exclusive remedy with respect
to a breach of this Agreement shall be the indemnities provided by Section 9.02
of the Purchase Agreement, except that any dispute between the

                                     -8-

parties arising hereunder for which such indemnities are being sought shall

hereunder if such delay, omission, error or failure is corrected within 20
Business Days of receipt of notice of such delay, omission, error or failure and
neither party shall have been prejudiced.

          Section 9.3.   ADJUSTMENTS.  If the liability of the Company under any

and complaints from state insurance regulators, brokers and other service
providers and reinsureds, all policyholder complaints and complaints received

balance due either party, as indicated in the monthly report, shall be remitted
to the other party within 15 days of the delivery of said monthly report.  The
requirements of this Section 10.1 shall terminate if, for twelve consecutive
months, no amounts are reported as due either party with respect to the
Insurance Contracts; PROVIDED, such requirements shall be reinstated and shall
continue in effect for an additional twelve months if at any time following such
termination, any balance or amount becomes due either party under this
Agreement.

business day of each January, April, July and October, Zenith shall provide the
Company with a quarterly or annual report containing the financial, accounting
and actuarial information necessary to prepare regulatory, tax and GAAP monthly,
quarterly and annual financial statements and returns and satisfy other related

          Section 12.1.  PAYMENTS BY ZENITH.  Zenith hereby agrees that all
amounts due under this Agreement with respect to all Quota Share Policies shall
be payable by Zenith on the basis of the liability of the Company under such
contracts, without diminution because of the insolvency, liquidation or
rehabilitation of the Company Insurance Subsidiary.  Zenith shall make payments
due hereunder with respect to Quota Share Policies directly to the Company or to
its conservator, receiver, liquidator or other statutory successor.

          Section 12.2.  CLAIMS.  It is agreed that any conservator, receiver,
liquidator or statutory successor of the Company shall give prompt written
notice to Zenith of the pendency or submission of a claim under any Insurance
Contract.  With respect to any Insurance Contract, during the pendency of such
claim, Zenith may investigate such claim and interpose, at its own expense, in
the proceeding where such claim is to be adjudicated, any defense available to
the Company or its conservator, receiver, liquidator or statutory successor. 
The expense thus incurred by Zenith is chargeable against the Company as a part
of the expense of insolvency, liquidation or rehabilitation to the extent of a
proportionate share of the benefit which accrues to the Company solely as a
result of the defense undertaken by Zenith.  Where Zenith and other assuming
companies are involved in the same claim and a majority in interest elect to
interpose a defense to such claim, the expense shall be apportioned in
accordance with the terms of the insurance agreement as though such expense had
been incurred by the Company.

Agreement to the contrary, any balances or amounts due from one party to the
other under this Agreement are deemed mutual debts or credits, as the case may
be, and shall be set off, and only the balance shall be allowed or paid.

          Section 14.1.  SOLE BENEFICIARY.  Zenith's quota share reinsurance 
of 100% of the Insurance Liabilities of the Company with respect to any of 
the Quota Share Policies is intended for the sole benefit of the parties to 
this Agreement and shall not create any right on the part of any 
Policyholder, insured, claimant or beneficiary under such Quota Share 
Policies against Zenith or any legal relation between such Policyholders, 
insureds, claimants or beneficiaries and Zenith.

difference arising under this Agreement that cannot be resolved by agreement 
among the parties hereto shall be decided by arbitration in accordance with 
this Article XV.  Any such arbitration shall be conducted expeditiously and 
confidentially in accordance with the Commercial Arbitration Rules of the 
American Arbitration Association ("AAA") as such rules shall be in effect on 
the date of delivery of demand for arbitration.  Any such arbitration shall 
be heard and conducted in New York, New York.  Notwithstanding the rules of 
the AAA, the arbitration panel in any such arbitration shall consist of three 
persons who must be disinterested current or retired officers of insurance or 
reinsurance companies other than the parties to this Agreement or their 
Affiliates.  Within twenty days of delivery of any demand for arbitration 
hereunder, the Company and Zenith shall each appoint one arbitrator, and the 
two arbitrators so selected shall appoint the third arbitrator within twenty 
days of their appointment.  In the event the two selected arbitrators are 
unable to agree upon the selection of a third arbitrator after reasonable 
efforts, a panel of seven qualified persons shall be requested from the AAA.  
The parties shall alternately strike one person with the last remaining 
person being the third designated arbitrator; the party responding to the 
initial demand for arbitration shall have the first turn. Each party shall 
pay the fees of its own attorneys, expenses of witnesses and all other 
expenses connected with the presentation of such party's case.  One-half of 
any remaining costs of any arbitration, including the cost of the record or 
transcripts thereof, if any, administrative fees and all other fees involved 
shall be paid by Zenith, and the remaining one-half shall be paid by the 
Company.

          Section 15.2.  DECISION.  The arbitrators shall render a decision 
within 60 days of the end of the arbitration hearing.  The arbitrators shall 
consider customary and standard practices in the insurance business.  They 
shall decide by a majority vote of the arbitrators.  All conclusions of law 
reached by the

arbitrators shall be made in accordance with the internal substantive laws of 
the State of New York without regard to conflict of laws principles.  Any 
award rendered by the arbitrators shall be accompanied by a written opinion 
setting forth the findings of fact and conclusions of law relied upon in 
reaching their decision.  There shall be no appeal from their written 
decision. Judgment may be entered on the decision of the arbitrators by any 
court having jurisdiction.

          Section 15.3.  CONFIDENTIALITY.  Zenith and the Company agree that 
the existence, conduct and content of any arbitration shall be kept 
confidential and no party shall disclose to any person any information about 
such arbitration, except as may be required by law or for financial reporting 
purposes in each party's financial statements.

          Section 15.4.  SURVIVAL OF ARTICLE.  This Article XV shall survive 
termination of this Agreement.

          Section 15.5.  OTHER ACTIONS.  Submission of a matter to 
arbitration shall be a condition precedent to any right to institute a 
proceeding at law or in equity concerning such matter, except for injunctive 
or other provisional relief pending the arbitration of a matter subject to 
arbitration pursuant to this Agreement.  Subject to the foregoing, each party 
hereto consents to the non exclusive jurisdiction of the United States 
District Court for the Southern District of New York (the "Chosen Court") in 
respect of any claim arising out of, related to or contemplated by this 
Agreement, (i) waives any objection to laying venue in any such action or 
proceeding in the Chosen Court, (ii) waives any objection that at the Chosen 
Court is an inconvenient forum or does not have jurisdiction over any party 
hereto and (iii) agrees that service of process upon such party in any such 
action or proceeding shall be effective if notice is given in accordance with 
Section 16.02 of this Agreement.

     ability to meet current obligations to policyholders, but its financial
     strength is vulnerable to adverse changes in underwriting and economic
     conditions.

     surplus) and/or operating experience.

STANDARD & POOR'S DEFINITIONS:

                    ASSUMPTION AND INDEMNITY REINSURANCE AGREEMENT

          THIS ASSUMPTION AND INDEMNITY REINSURANCE AGREEMENT (this 
"Agreement"), dated as of 12:01 a.m. New York City Time on April 1, 1998 (the 
"Effective Date"), is made by and between ZENITH INSURANCE COMPANY, a stock 
insurance company organized under the laws of the State of California 
("Zenith"), and RISCORP INSURANCE COMPANY, a stock insurance company 
organized under the laws of the State of Florida (the "Company").

          WHEREAS, Zenith and the Company have entered into the Purchase 
Agreement (as defined below); and

          WHEREAS, the Purchase Agreement provided for Zenith and the Company 
to enter into an indemnity reinsurance agreement; 

          WHEREAS, the parties have agreed to amend the Purchase Agreement to 
provide for Zenith and the Company to enter into an assumption reinsurance 
agreement; 

          WHEREAS, Zenith and the Company are entering into this Agreement 
pursuant to the Purchase Agreement, as so amended; 

          WHEREAS, the Company has agreed to cede to Zenith, and Zenith has 
agreed to assume certain liabilities and obligations of the Company under the 
Insurance Contracts (as defined in the Purchase Agreement).

          NOW, THEREFORE, in consideration of the mutual covenants and 
promises and upon the terms and conditions set forth herein, the parties 
hereto agree as follows:

                                    ARTICLE I

                                   DEFINITIONS

          Section 1.1.  DEFINITIONS.  Capitalized terms used herein and not 
otherwise defined in this Agreement shall have the meanings given to them in 
the Purchase Agreement.  As used in this Agreement, the following terms shall 
have the following meanings:

          "CLAIMANT" means any claimant under any Insurance Contract who (a) 
has an open claim on the Effective Date, or (b) files a claim after the 
Effective Date.

          "EFFECTIVE DATE" means the date specified in the first paragraph 
hereof.

          "INSURANCE CONTRACTS" shall mean those Insurance Contracts (as 
defined in the Purchase Agreement) issued by the Company.

<PAGE>

          "INSURANCE LIABILITIES" shall mean those Insurance Liabilities (as 
defined in the Purchase Agreement) arising under or in connection with the 
Insurance Contracts.

          "NOVATED POLICIES" means those Insurance Contracts for which: (a) 
the Company or Zenith has received a written acceptance by the Policyholder 
of the transfer and assumption under this Agreement; and (b) with respect to 
any Insurance Contract that was issued or issued for delivery in a state 
where written acceptance by the Policyholder is not required by law or the 
appropriate regulatory authority to effect an assumption and novation, (i) 
the Policyholder is deemed to have accepted the transfer and assumption under 
this Agreement by paying premiums directly to Zenith or taking such other 
action as may be recognized under applicable state law as evidence of the 
Policyholder's acceptance of the transfer and assumption, or (ii) the 
Policyholder has, following the mailing to the Policyholder of such notices 
as may be prescribed by applicable state law, neither accepted nor rejected 
the transfer and assumption within a timeframe under which applicable state 
law or appropriate regulatory authority permits the policyholder to be deemed 
to have accepted the transfer and assumption.  Any claim made by any Claimant 
under an Insurance Contract which expired prior to the Effective Date shall, 
subject to the last sentence of this paragraph, be deemed to be a claim under 
a Novated Policy.  If an Insurance Contract defined herein as a Novated 
Policy is determined by law or an appropriate regulatory authority, by 
judicial decision or otherwise to be not novated, such Insurance Contract 
shall for all purposes of this Agreement be deemed retroactive to the 
Effective Date to be a Quota Share Policy.  

          "POLICYHOLDER" means each holder of an Insurance Contract that is 
in force on the Effective Date.

          "PURCHASE AGREEMENT" means the Asset Purchase Agreement, dated as 
of June 17, 1997, as amended, among Zenith, RISCORP National Insurance 
Company, the Company, RISCORP Property Casualty Insurance Company, RISCORP, 
Inc., RISCORP of Florida, Inc., RISCORP Management Services, Inc., RISCORP 
Managed Care Services, Inc., RISCORP Insurance Services, Inc., CompSource, 
Inc., RISCORP of Illinois, Inc., Independent Association Administrators 
Incorporated, RISCORP Real Estate Holdings, Inc., RISCORP Acquisition, Inc., 
RISCORP West, Inc., RISCORP Services, Inc., RISCORP Staffing Solutions 
Holdings, Inc., RISCORP Staffing Solutions, Inc. I and RISCORP Staffing 
Solutions, Inc. II.

          "QUOTA SHARE POLICIES" shall have the meaning set forth in Section 2.3
hereof.  

                                      ARTICLE II

                                  BUSINESS REINSURED

          Section 2.1.  BUSINESS REINSURED.  Subject to all of the terms and 
conditions contained herein, the Company hereby

                                      -2-

<PAGE>

cedes to Zenith, and Zenith hereby assumes as reinsurance from the Company, 
all of the rights and obligations of the Company under each of the Insurance 
Contracts.

          Section 2.2.  NOVATED POLICIES.  Zenith shall be the successor to 
the Company under the Novated Policies that it assumes as if the Novated 
Policies were direct obligations originally issued by Zenith.  Zenith shall 
be substituted in the place and stead of the Company so as to effect a 
novation of the respective Insurance Contracts and release the Company from 
any and all rights and obligations thereunder.  Each insured under a Novated 
Policy shall disregard the Company as a party thereto and treat Zenith as if 
it had been originally obligated thereunder except as otherwise provided 
herein.  The insureds shall file claims arising under the Novated Policies on 
or after the effective date of such novation directly with Zenith.  The 
insureds under the Novated Policies shall also have a right to assert claims 
related to such Novated Policies directly against Zenith and Zenith hereby 
consents to be subject to such claims by any insured under the Novated 
Policy; PROVIDED, HOWEVER, that the rights of any insured under any Insurance 
Contract shall be limited to and consist of those rights set forth in such 
Insurance Contract (including any rider or endorsement thereto), and no 
insured shall have the right to receive any greater amount under any 
Insurance Contract than such insured would have had in the absence of this 
Agreement (except that in assessing such right no effect shall be given to 
any bankruptcy, liquidation, insolvency, reorganization or moratorium of the 
Company, or the effect of laws or legal procedures affecting enforcement of 
creditors' rights against the Company generally).  Payments made to insureds 
in discharge of obligations on Novated Policies to provide direct coverage to 
insureds will diminish any obligation in respect to those Novated Policies 
which Zenith may have to the estate of the Company if it shall be in 
receivership, liquidation or rehabilitation proceedings.  

          Section 2.3.  QUOTA SHARE POLICIES.  To the extent Zenith has not 
for any reason assumed by novation any Insurance Contracts or Insurance 
Liabilities, Zenith shall accept and reinsure, on a quota share basis, 100% 
of Insurance Liabilities under such Insurance Contracts (the "Quota Share 
Policies"), in accordance with the terms and conditions of this Agreement, 
and hereby agrees to pay directly, on behalf of the Company, any claims or 
losses reinsured under this Agreement which arise under such Quota Share 
Policies; PROVIDED, HOWEVER, that the insureds under such Quota Share 
Policies shall not have the right to assert claims related to such Quota 
Share Policies directly against Zenith.  A payment made to an insured in 
discharge of obligations of RISCORP to provide direct coverage to the insured 
will diminish the obligation in respect thereof which Zenith may have to the 
estate of the Company if it shall be in receivership, liquidation or 
rehabilitation proceedings.

                                      -3-

<PAGE>

          Section 2.4.  TERMS; CONDITIONS.  All Insurance Liabilities for 
which Zenith shall assume liability hereunder, either as Novated Policies or 
Quota Share Policies, are subject in all respects to the same written terms, 
conditions, waivers, modifications, alterations and cancellations as the 
Insurance Contracts.  Zenith accepts and assumes the Insurance Liabilities 
subject to all defenses, setoffs and counterclaims to which the Company would 
be entitled with respect to the Insurance Contracts.  The parties agree that 
no such defenses, setoffs or counterclaims are waived under this Agreement 
and that as of the Effective Date, Zenith shall be fully subrogated to all 
such defenses, setoffs and counterclaims and be entitled to the full benefits 
thereof.

                                     ARTICLE III

                               ASSUMPTION CERTIFICATES

          Section 3.1.  NOTICE OF TRANSFER AND CERTIFICATE OF ASSUMPTION.(a) 
Zenith, with the cooperation and assistance of the Company, shall prepare for 
mailing to every Policyholder a Notice of Transfer and Certificate of 
Assumption, including a form for rejection or acceptance and a self-addressed 
return envelope, substantially in the form attached hereto as EXHIBIT A 
(collectively, the "Policyholder Notices"), subject to changes required by 
state law or required by any state insurance regulator as a condition for 
approval of the mailing of such Policyholder Notices to Policyholders.  The 
Company shall cooperate and assist Zenith in the preparation and mailing of 
the Policyholder Notices as provided herein.  Zenith shall mail Policyholder 
Notices by certified mail, return receipt requested, to the Policyholders 
located in a particular state within thirty days of receipt of all regulatory 
approvals necessary for such mailing.

     (b)  Zenith, with the cooperation and assistance of the Company, shall 
prepare for mailing and mail, within thirty days of receipt of all regulatory 
approvals necessary for such mailing, to each holder of an Insurance Contract 
which expired without renewal during the two year period immediately 
prececeding the Effective Date a Notice of Transfer and Assumption 
substantially in the form attached hereto as EXHIBIT B (collectively, the 
"Expired Policy Notices"), subject to changes required by state law or 
required by any state insurance regulator as a condition for approval of the 
mailing of such Expired Policy Notices to said holders of Insurance Contracts 
and Claimants.  

     (c)  Zenith, with the cooperation and assistance of the Company, shall 
prepare for mailing and mail, within thirty days of the Effective Date, to 
each Claimant who has an open claim on the Effective Date, a Notice 
substantially in the form attached hereto as EXHIBIT C (collectively, the 
"Claimant Notices"), subject to changes required by state law or required by 
any state 

                                      -4-

<PAGE>

insurance regulator as a condition for approval of the mailing of such 
Claimant Notices to said holders of Insurance Contracts and Claimants.  In 
addition, Zenith, with the cooperation and assistance of the Company, shall 
prepare and mail a Claimant Notice to each Claimant who is not a Policyholder 
(as defined herein), but who, after the Effective Date, files a claim under 
any Insurance Contract.

          Section 3.2.  EFFECT OF NOTICE.  A Policyholder shall be deemed to 
have accepted the transfer and assumption under this Agreement (1) upon 
receipt by Zenith of the Policyholder's written acceptance of the transfer 
and assumption, or (2) with respect to any Insurance Contract issued or 
issued for delivery in a state where written acceptance by the Policyholder 
is not required by the appropriate regulatory authority to effect an 
assumption and novation, upon taking such action, or failing to take any 
action following the mailing of the Policyholder Notice, as specified in 
Schedule 3.2. attached hereto.      

                                      ARTICLE IV

                                POLICY ADMINISTRATION

          Section 4.1.  POLICY ADMINISTRATION BY ZENITH.  The Company grants 
to Zenith authority in all matters relating to the administration of the 
Insurance Contracts assumed by Zenith to the extent such authority may be 
granted pursuant to applicable law and agrees to cooperate fully with Zenith 
in the transfer of such administration.  Zenith agrees, at its expense, to be 
responsible for such administration.  In order to assist and to evidence more 
fully the substitution of Zenith in the place and stead of the Company, the 
Company hereby nominates, constitutes and appoints Zenith as its 
attorney-in-fact with respect to the rights, duties, privileges and 
obligations of the Company in and to the Insurance Contracts assumed by 
Zenith, with full power and authority to act in the name, place and stead of 
the Company with respect to such Insurance Contracts including, without 
limitation, the power without reservation, to service all such Insurance 
Contracts, to adjust, to defend, to settle and to pay all claims, to recover 
salvage and subrogation for any losses incurred and to take such other and 
further actions as may be necessary or desirable to effect the transactions 
contemplated by this Agreement.  In addition to other responsibilities set 
forth in this Agreement, Zenith shall also issue on the Company's behalf, but 
wherever possible in the name of Zenith, all Insurance Contracts assumed by 
Zenith which the Company is contractually or otherwise obligated to issue on 
and after the Effective Date.

          Section 4.2.  FORWARDING OF NOTICES AND OTHER COMMUNICATIONS.  The 
Company agrees that, after the Effective Date, it will forward to Zenith, 
within forty-five (45) days of receipt, all notices and other written 
communications received by it relating to the Insurance Contracts assumed by 
Zenith 

                                      -5-

(including, without limitation, all inquiries or complaints from state 
insurance regulators, agents, brokers and insureds and all notices of claims, 
suits and actions for which it receives services of process).  

                                      ARTICLE V

                                    CONSIDERATION

          Section 5.1.  INITIAL CONSIDERATION.  In consideration of Zenith's 
assumption of the Insurance Liabilities hereunder, the Company shall transfer 
to Zenith the Transferred Assets pursuant to Section 2.01 of the Purchase 
Agreement related to the Company's Insurance Liabilities.

          Section 5.2.  FUTURE PREMIUMS.  Zenith is entitled to receive all 
premiums and other consideration paid on or after the Effective Date with 
respect to the Insurance Contracts.  In the event that the Company receives 
any premiums or other consideration with respect to an Insurance Contract on 
or after the Effective Date, it shall promptly remit such premiums or other 
consideration to Zenith, along with pertinent information in its possession 
relating to such premiums, including information as to the Insurance Contract 
and period to which such premium relates. Zenith shall assume all 
responsibility for billing and collection of premiums.  The Company shall 
reasonably cooperate with Zenith in causing insureds under the Insurance 
Contracts to pay premiums to Zenith after the Effective Date.

                                      ARTICLE VI

                          RESERVES; CREDIT FOR REINSURANCE 

          Section 6.1.  RESERVES; CREDIT FOR REINSURANCE.  Zenith shall 
maintain all insurance licenses necessary to permit the Company to obtain 
full financial statement credit in all applicable jurisdictions for the 
reinsurance provided to it by Zenith pursuant to this Agreement, PROVIDED 
that if Zenith shall fail to maintain such licenses, it shall provide the 
Company with collateral security permitted under applicable law for purposes 
of obtaining financial statement credit for the reinsurance provided under 
this Agreement.  Any unearned premium, loss and loss adjustment expense 
reserves required by the foregoing in no event shall be less than the amounts 
required under the law of any jurisdiction having regulatory authority with 
respect to the establishment of reserves relating to the Insurance Contracts.

                  ASSIGNMENT OF CEDED REINSURANCE AGREEMENTS

          Section 7.1.  ASSIGNMENT.  (a)  As of the Effective Date, the 
Company shall transfer, set over, assign and convey to Zenith all of its 
right, title and interest in any amount held by or due from the assuming 
reinsurers under the reinsurance agreements listed in SCHEDULE 7.1-A 
("Schedule 7.1-A Reinsurance"), including (i) amounts held by or which may 
become due from the assuming reinsurers thereunder for losses or loss 
adjustment expenses on Insurance Contracts for which the Reinsurer has 
assumed liability or for losses paid by the Company prior to the Effective 
Date, and (ii) letters of credit, trust funds and other security mechanisms 
outstanding for the benefit of the Company pursuant to the terms of any of 
the Schedule 7.1-A Reinsurance.  The Company hereby authorizes Zenith, as of 
the Effective Date, to prepare and submit, on the Company's behalf and in the 
Company's name, all statements and reports required of the Company under the 
Schedule 7.1-A Reinsurance, and further authorizes Zenith to take all other 
actions required of the Company under the Schedule 7.1-A Reinsurance or 
otherwise permitted thereunder, and Zenith agrees to prepare and submit such 
reports and take all such actions, except that Zenith shall not undertake to 
pay on behalf of the Company, and shall not be obligated hereunder to pay, 
any amount due to the reinsurers under the Schedule 7.1-A Reinsurance unless 
the Company's obligation to pay such amount shall have been accrued as a 
liability on the Final Business Balance Sheet.  

          (b)  As of the Effective Date, the Reinsurer shall be substituted 
for and succeed to all of the rights and liabilities of the Company, under 
the reinsurance agreements listed in SCHEDULE 7.1-B (the "Schedule 7.1-B 
Reinsurance" and, together with the Schedule 7.1-A Reinsurance, the "Ceded 
Reinsurance") and shall be recognized for all purposes as the "Company" 
thereunder in substitution for the Company.  The Company shall transfer, set 
over, assign and convey to Zenith all of its rights and obligations of any 
nature whatsoever under the Schedule 7.1-B Reinsurance, including (i) amounts 
held by or which may become due from assuming reinsurers with respect to any 
reinsurance ceded by the Company to the reinsurer thereunder, and (ii) 
letters of credit, trust funds and other security mechanisms outstanding for 
the benefit of the Company pursuant to the terms of any of the Ceded 
Reinsurance.  Zenith shall accept such conveyance, transfer and assignment of 
the Company's rights under the Schedule 7.1-B Reinsurance and assumes all of 
the Company's obligations under the Schedule 7.1-B Reinsurance existing on or 
arising after the Effective Date.  The assignment and assumption of the 
Schedule 7.1-B Reinsurance effected by this Section 7.1 shall be effective 
only if such assignment (i) is permitted under the terms of such Schedule 
7.1-B Reinsurance or as otherwise consented to by the reinsurer thereunder, 
and (ii) shall preserve fully the obligations of the reinsurers thereunder in 
respect of 

                                      -7-

<PAGE>

the Insurance Contracts.  If the Company's rights and obligations under any 
such Schedule 7.1-B Reinsurance are not assigned to and assumed by Zenith, 
(i) after the Effective Date, Zenith shall be responsible for the payment of 
all premiums and other considerations required to be paid by the Company in 
respect of any of the Schedule 7.1-B Reinsurance, (ii) all reinsurance 
recoveries attributable to any of the Schedule 7.1-B Reinsurance are assigned 
and shall accrue to the benefit of Zenith hereunder by operation of this 
Section 7.1 and shall, upon receipt thereof by the Company, be paid promptly 
thereby to Zenith upon and in accordance with its direction, and (iii) such 
assignment shall be effective at such time as the assignment may be effected 
while preserving fully the obligations of the reinsurer under the respective 
Schedule 7.1-B Reinsurance.  

          (c)  The Company shall reasonably cooperate with Zenith in causing 
reinsurers under the Ceded Reinsurance to pay reinsurance recoveries to 
Zenith after the Effective Date.

          Section 7.2.  CEDED REINSURANCE COLLATERAL.  To the extent 
necessary to effect any transfer or assignment pursuant to this Section 7.1 
of any assumed reinsurance, the Company hereby appoints Zenith as 
attorney-in-fact for the Company to act for and on behalf of it with respect 
to letters of credit, trust funds and other security mechanisms outstanding 
for the benefit of the Company pursuant to the terms of any of the Ceded 
Reinsurance, and the Company shall execute and deliver to Zenith such 
additional instruments as Zenith may reasonably request to give effect to 
such appointment as attorney-in-fact, and to provide appropriate evidence 
that the Company has assigned to Zenith all of its rights under the Ceded 
Reinsurance with respect to any such letters of credit, trust funds or other 
accounting mechanism.  Zenith shall use its reasonable best efforts to the 
extent deemed reasonably necessary by Zenith, to cause the reinsurers under 
the Ceded Reinsurance to provide replacement letters of credit, trust funds 
or other security mechanisms, as applicable, naming Zenith as the beneficiary 
thereof in amounts and with terms substantially similar to those currently 
provided by such reinsurers for the benefit of the Company.

                                     ARTICLE VIII

                                   INDEMNIFICATION

          Section 8.1.  SOLE REMEDY.  Notwithstanding anything to the 
contrary in this Agreement, the Company shall not settle any claim, waive any 
right, defense, setoff or counterclaim with respect to, or amend, commute or 
terminate, any Insurance Contract or Ceded Reinsurance without the prior 
written consent of Zenith, except in accordance with the provisions of the 
indemnities referred to in the following sentence.  The Company's sole and 
exclusive remedy with respect to a breach of this Agreement shall be the 
indemnities provided by Section 9.02 of 

                                      -8-

<PAGE>

the Purchase Agreement, except that any dispute between the parties arising 
hereunder for which such indemnities are being sought shall be subject to 
arbitration pursuant to Article XV hereof.

                                      ARTICLE IX

                                  GENERAL PROVISIONS

          Section 9.1.   INSPECTION.  Zenith and the Company, or their 
designated representatives, may inspect, at the place where such records are 
located, any and all books and records of the other parties hereto reasonably 
relating to this Agreement, during normal business hours and upon reasonable 
notice.  The rights of the parties under this Section 9.1 shall survive 
termination of this Agreement.

          Section 9.2.  MISUNDERSTANDINGS AND OVERSIGHTS.  Any delay, 
omission, error or failure to pay amounts due or to perform any other act 
required by this Agreement that is unintentional and caused by 
misunderstanding or oversight shall not be held to relieve either party to 
this Agreement from any obligation hereunder if such delay, omission, error 
or failure is corrected within 20 Business Days of receipt of notice of such 
delay, omission, error or failure and neither party shall have been 
prejudiced.

          Section 9.3.   ADJUSTMENTS.  If the liability of the Company under 
any of the Insurance Contracts is changed as a result of a change required by 
law or regulation or any other reason, Zenith will share in the change 
proportionately (100%) to the amount reinsured hereunder.

          Section 9.4.   COMMUNICATIONS RELATING TO THE INSURANCE CONTRACTS. 
After the Effective Date, the Company and Zenith each shall forward promptly 
to the other copies of all notices and other written communications it 
receives relating to the Insurance Contracts (including without limitation, 
all inquiries and complaints from state insurance regulators, brokers and 
other service providers and reinsureds, all policyholder complaints and 
complaints received from other claimants under the Insurance  Contracts and 
all notices of claims, suits and actions for which it receives service of 
process).  As used in this Section, "complaint" means any written 
communication primarily expressing a grievance against the Company or Zenith. 
  

          Section 9.5.  DUTY OF COOPERATION.  The Company and Zenith shall 
cooperate fully with the other in all reasonable respects in order to 
accomplish the objectives of this Agreement.

          Section 10.1.  ACCOUNTING REPORTS.  On or before the last Business 
Day of each month, Zenith will provide the Company with reports of activities

amounts due the Company or Zenith, as the case may be, as reimbursement for 
paid claims, premiums or other amounts due with respect to the Insurance

                                  TERMINATION

          Section 11.1.  TERMINATION.  Except as mutually agreed by the 
Company and Zenith, this Agreement shall be unlimited in duration.  

                                   ARTICLE XII

                                   INSOLVENCY

          Section 12.1.  PAYMENTS BY ZENITH.  Zenith hereby agrees that all 
amounts due under this Agreement with respect to all Quota Share Policies 
shall be payable by Zenith on the basis of the liability of the Company under 
such contracts, without diminution because of the insolvency, liquidation or 
rehabilitation of the Company Insurance Subsidiary.  Zenith shall make 
payments due hereunder with respect to Quota Share Policies directly to the 
Company or to its conservator, receiver, liquidator or other statutory 
successor.

          Section 12.2.  CLAIMS.  It is agreed that any conservator, 
receiver, liquidator or statutory successor of the Company shall give prompt 
written notice to Zenith of the pendency or submission of a claim under any 
Insurance Contract.  With respect to any Insurance Contract, during the 
pendency of such claim, Zenith may investigate such claim and interpose, at 
its own expense, in the proceeding where such claim is to be adjudicated, any 
defense available to the Company or its conservator, receiver, liquidator or 
statutory successor. The expense thus incurred by Zenith is chargeable 
against the Company as a part of the expense of insolvency, liquidation or 
rehabilitation to the extent of a proportionate share of the benefit which 
accrues to the Company solely as a result of the defense undertaken by 
Zenith.  Where Zenith and other assuming companies are involved in the same 
claim and a majority in interest elect to interpose a defense to such claim, 
the expense shall be apportioned in accordance with the terms of the 
insurance agreement as though such expense had been incurred by the Company.

                                   ARTICLE XIII

                                      OFFSET

          Section 13.1.  OFFSET. Notwithstanding any provisions of this 
Agreement to the contrary, any balances or amounts due from one party to the 
other under this Agreement are deemed mutual debts or credits, as the case 
may be, and shall be set off, and only the balance shall be allowed or paid.

                     RIGHTS WITH RESPECT TO QUOTA SHARE POLICIES

          Section 14.1.  SOLE BENEFICIARY.  Zenith's quota share reinsurance 
of 100% of the Insurance Liabilities of the Company with respect to any of 
the Quota Share Policies is intended for the sole benefit of the parties to 
this Agreement and shall not create any right on the part of any 
Policyholder, insured, claimant or beneficiary under such Quota Share 
Policies against Zenith or any legal relation between such Policyholders, 
insureds, claimants or beneficiaries and Zenith.   

                                    ARTICLE XV

difference arising under this Agreement that cannot be resolved by agreement 
among the parties hereto shall be decided by arbitration in accordance with 
this Article XV.  Any such arbitration shall be conducted expeditiously and 
confidentially in accordance with the Commercial Arbitration Rules of the 
American Arbitration Association ("AAA") as such rules shall be in effect on 
the date of delivery of demand for arbitration.  Any such arbitration shall 
be heard and conducted in New York, New York.  Notwithstanding the rules of 
the AAA, the arbitration panel in any such arbitration shall consist of three 
persons who must be disinterested current or retired officers of insurance or 
reinsurance companies other than the parties to this Agreement or their 
Affiliates.  Within twenty days of delivery of any demand for arbitration 
hereunder, the Company and Zenith shall each appoint one arbitrator, and the 
two arbitrators so selected shall appoint the third arbitrator within twenty 
days of their appointment.  In the event the two selected arbitrators are 
unable to agree upon the selection of a third arbitrator after reasonable 
efforts, a panel of seven qualified persons shall be requested from the AAA.  
The parties shall alternately strike one person with the last remaining 
person being the third designated arbitrator; the party responding to the 
initial demand for arbitration shall have the first turn. Each party shall 
pay the fees of its own attorneys, expenses of witnesses and all other 
expenses connected with the presentation of such party's case.  One-half of 
any remaining costs of any arbitration, including the cost of the record or 
transcripts thereof, if any, administrative fees and all other fees involved 
shall be paid by Zenith, and the remaining one-half shall be paid by the 
Company.

          Section 15.2.  DECISION.  The arbitrators shall render a decision 
within 60 days of the end of the arbitration hearing.  The arbitrators shall 
consider customary and standard practices in the insurance business.  They 
shall decide by a majority vote of the arbitrators.  All conclusions of law 
reached by the 

                                      -12-

<PAGE>

arbitrators shall be made in accordance with the internal substantive laws of 
the State of New York without regard to conflict of laws principles.  Any 
award rendered by the arbitrators shall be accompanied by a written opinion 
setting forth the findings of fact and conclusions of law relied upon in 
reaching their decision.  There shall be no appeal from their written 
decision. Judgment may be entered on the decision of the arbitrators by any 
court having jurisdiction.

          Section 15.3.  CONFIDENTIALITY.  Zenith and the Company agree that 
the existence, conduct and content of any arbitration shall be kept 
confidential and no party shall disclose to any person any information about 
such arbitration, except as may be required by law or for financial reporting 
purposes in each party's financial statements.

          Section 15.4.  SURVIVAL OF ARTICLE.  This Article XV shall survive 
termination of this Agreement.

          Section 15.5.  OTHER ACTIONS.  Submission of a matter to 
arbitration shall be a condition precedent to any right to institute a 
proceeding at law or in equity concerning such matter, except for injunctive 
or other provisional relief pending the arbitration of a matter subject to 
arbitration pursuant to this Agreement.  Subject to the foregoing, each party 
hereto consents to the non exclusive jurisdiction of the United States 
District Court for the Southern District of New York (the "Chosen Court") in 
respect of any claim arising out of, related to or contemplated by this 
Agreement, (i) waives any objection to laying venue in any such action or 
proceeding in the Chosen Court, (ii) waives any objection that at the Chosen

hereto and (iii) agrees that service of process upon such party in any such 
action or proceeding shall be effective if notice is given in accordance with 
Section 16.02 of this Agreement.

                    ASSUMPTION AND INDEMNITY REINSURANCE AGREEMENT

          THIS ASSUMPTION AND INDEMNITY REINSURANCE AGREEMENT (this
"Agreement"), dated as of 12:01 a.m. New York City Time on April 1, 1998 (the
"Effective Date"), is made by and between ZENITH INSURANCE COMPANY, a stock
insurance company organized under the laws of the State of California
("Zenith"), and RISCORP PROPERTY & CASUALTY INSURANCE COMPANY, a stock insurance
company organized under the laws of the State of Florida (the "Company").

          WHEREAS, Zenith and the Company have entered into the Purchase
Agreement (as defined below); and

          WHEREAS, the Purchase Agreement provided for Zenith and the Company to
enter into an indemnity reinsurance agreement; 

          WHEREAS, the parties have agreed to amend the Purchase Agreement to
provide for Zenith and the Company to enter into an assumption reinsurance
agreement; 

          WHEREAS, Zenith and the Company are entering into this Agreement
pursuant to the Purchase Agreement, as so amended; 

          WHEREAS, the Company has agreed to cede to Zenith, and Zenith has
agreed to assume certain liabilities and obligations of the Company under the
Insurance Contracts (as defined in the Purchase Agreement).

          NOW, THEREFORE, in consideration of the mutual covenants and promises
and upon the terms and conditions set forth herein, the parties hereto agree as
follows:


                                  ARTICLE I

                                 DEFINITIONS

          Section 1.1  DEFINITIONS.  Capitalized terms used herein and not
otherwise defined in this Agreement shall have the meanings given to them in the
Purchase Agreement.  As used in this Agreement, the following terms shall have
the following meanings:

          "CLAIMANT" means any claimant under any Insurance Contract who (a) has
an open claim on the Effective Date, or (b) files a claim after the Effective
Date.

          "EFFECTIVE DATE" means the date specified in the first paragraph
hereof.

          "INSURANCE CONTRACTS" shall mean those Insurance Contracts (as defined
in the Purchase Agreement) issued by the Company.



<PAGE>

          "INSURANCE LIABILITIES" shall mean those Insurance Liabilities (as
defined in the Purchase Agreement) arising under or in connection with the
Insurance Contracts.

          "NOVATED POLICIES" means those Insurance Contracts for which: (a) the
Company or Zenith has received a written acceptance by the Policyholder of the
transfer and assumption under this Agreement; and (b) with respect to any
Insurance Contract that was issued or issued for delivery in a state where
written acceptance by the Policyholder is not required by law or the appropriate
regulatory authority to effect an assumption and novation, (i) the Policyholder
is deemed to have accepted the transfer and assumption under this Agreement by
paying premiums directly to Zenith or taking such other action as may be
recognized under applicable state law as evidence of the Policyholder's
acceptance of the transfer and assumption, or (ii) the Policyholder has,
following the mailing to the Policyholder of such notices as may be prescribed
by applicable state law, neither accepted nor rejected the transfer and
assumption within a timeframe under which applicable state law or appropriate
regulatory authority permits the policyholder to be deemed to have accepted the
transfer and assumption.  Any claim made by any Claimant under an Insurance
Contract which expired prior to the Effective Date shall, subject to the last
sentence of this paragraph, be deemed to be a claim under a Novated Policy.  If
an Insurance Contract defined herein as a Novated Policy is determined by law or
an appropriate regulatory authority, by judicial decision or otherwise to be not
novated, such Insurance Contract shall for all purposes of this Agreement be
deemed retroactive to the Effective Date to be a Quota Share Policy.  

          "POLICYHOLDER" means each holder of an Insurance Contract that is in
force on the Effective Date.

          "PURCHASE AGREEMENT" means the Asset Purchase Agreement, dated as of

hereof.

                              BUSINESS REINSURED

          Section 2.1  BUSINESS REINSURED.  Subject to all of the terms and
conditions contained herein, the Company hereby cedes to Zenith, and Zenith
hereby assumes as reinsurance from the Company, all of the rights and
obligations of the Company under each of the Insurance Contracts.

          Section 2.2  NOVATED POLICIES.  Zenith shall be the successor to the
Company under the Novated Policies that it assumes as if the Novated Policies
were direct obligations originally issued by Zenith.  Zenith shall be
substituted in the place and stead of the Company so as to effect a novation of
the respective Insurance Contracts and release the Company from any and all
rights and obligations thereunder.  Each insured under a Novated Policy shall
disregard the Company as a party thereto and treat Zenith as if it had been
originally obligated thereunder except as otherwise provided herein.  The
insureds shall file claims arising under the Novated Policies on or after the
effective date of such novation directly with Zenith.  The insureds under the
Novated Policies shall also have a right to assert claims related to such
Novated Policies directly against Zenith and Zenith hereby consents to be
subject to such claims by any insured under the Novated Policy; PROVIDED,
HOWEVER, that the rights of any insured under any Insurance Contract shall be
limited to and consist of those rights set forth in such Insurance Contract
(including any rider or endorsement thereto), and no insured shall have the
right to receive any greater amount under any Insurance Contract than such
insured would have had in the absence of this Agreement (except that in
assessing such right no effect shall be given to any bankruptcy, liquidation,
insolvency, reorganization or moratorium of the Company, or the effect of laws
or legal procedures affecting enforcement of creditors' rights against the
Company generally).  Payments made to insureds in discharge of obligations to
provide direct coverage to insureds will diminish any obligation in respect to
those Novated Policies which Zenith may have to the estate of the Company if it
shall be in receivership, liquidation or rehabilitation proceedings.  

          Section 2.3  QUOTA SHARE POLICIES.  To the extent Zenith has not for
any reason assumed by novation any Insurance Contracts or Insurance Liabilities,
Zenith shall accept and reinsure, on a quota share basis, 100% of Insurance
Liabilities under such Insurance Contracts (the "Quota Share Policies"), in
accordance with the terms and conditions of this Agreement, and hereby agrees to
pay directly, on behalf of the Company, any claims or losses reinsured under
this Agreement which arise under such Quota Share Policies; PROVIDED, HOWEVER,
that the insureds under such Quota Share Policies shall not have the right to
assert claims related to such Quota Share Policies directly against Zenith.  A
payment made to an insured in discharge of

                                     -3-

obligations of RISCORP to provide direct coverage to the insured will 
diminish the obligation in respect thereof which Zenith may have to the 
estate of the Company if it shall be in receivership, liquidation or 
rehabilitation proceedings.  

          Section 2.4  TERMS; CONDITIONS.  All Insurance Liabilities for which
Zenith shall assume liability hereunder, either as Novated Policies or Quota
Share Policies, are subject in all respects to the same written terms,
conditions, waivers, modifications, alterations and cancellations as the
Insurance Contracts.  Zenith accepts and assumes the Insurance Liabilities
subject to all defenses, setoffs and counterclaims to which the Company would be
entitled with respect to the Insurance Contracts.  The parties agree that no
such defenses, setoffs or counterclaims are waived under this Agreement and that
as of the Effective Date, Zenith shall be fully subrogated to all such defenses,
setoffs and counterclaims and be entitled to the full benefits thereof.

Effective Date, a Notice substantially in the form attached hereto as EXHIBIT 
C (collectively, the "Claimant Notices"), subject to changes required by 
state law or required by any state insurance regulator as a condition for

          Section 3.2  EFFECT OF NOTICE.  A Policyholder shall be deemed to have
accepted the transfer and assumption under this Agreement(1) upon receipt by
Zenith of the Policyholder's written acceptance of the transfer and assumption,
or (2) with respect to any Insurance Contract issued or issued for delivery in a
state where written acceptance by the Policyholder is not required by the
appropriate regulatory authority to effect an assumption and novation, upon
taking such action, or failing to take any action following the mailing of the

Zenith authority in all matters relating to the administration of the Insurance
Contracts assumed by Zenith to the extent such authority may be granted pursuant
to applicable law and agrees to cooperate fully with Zenith in the transfer of
such administration.  Zenith agrees, at its expense, to be responsible for such
administration.  In order to assist and to evidence more fully the substitution
of Zenith in the place and stead of the Company, the Company hereby nominates,
constitutes and appoints Zenith as its attorney-in-fact with respect to the
rights, duties, privileges and obligations of the Company in and to the
Insurance Contracts assumed by Zenith, with full power and authority to act in

Contracts including, without limitation, the power without reservation, to
service all such Insurance Contracts, to adjust, to defend, to settle and to pay
all claims, to recover salvage and subrogation for any losses incurred and to
take such other and further actions as may be necessary or desirable to effect
the transactions contemplated by this Agreement.  In addition to other

Company's behalf, but wherever possible in the name of Zenith, all Insurance
Contracts assumed by Zenith which the Company is contractually or otherwise
obligated to issue on and after the Effective Date.

                      ASSIGNMENT OF CEDED REINSURANCE AGREEMENTS

          Section 7.1  ASSIGNMENT.  (a)  As of the Effective Date, the Company
shall transfer, set over, assign and convey to Zenith all of its right, title
and interest in any amount held by or due from the assuming reinsurers under the
reinsurance agreements listed in SCHEDULE 7.1-A ("Schedule 7.1-A Reinsurance"),
including (i) amounts held by or which may become due from the assuming
reinsurers thereunder for losses or loss adjustment expenses on Insurance
Contracts for which the Reinsurer has assumed liability or for losses paid by
the Company prior to the Effective Date, and (ii) letters of credit, trust funds
and other security mechanisms outstanding for the benefit of the Company
pursuant to the terms of any of the Schedule 7.1-A Reinsurance.  The Company
hereby authorizes Zenith, as of the Effective Date, to prepare and submit, on
the Company's behalf and in the Company's name, all statements and reports
required of the Company under the Schedule 7.1-A Reinsurance, and further
authorizes Zenith to take all other actions required of the Company under the
Schedule 7.1-A Reinsurance or otherwise permitted thereunder, and Zenith agrees
to prepare and submit such reports and take all such actions, except that Zenith
shall not undertake to pay on behalf of the Company, and shall not be obligated
hereunder to pay, any amount due to the reinsurers under the Schedule 7.1-A
Reinsurance unless the Company's obligation to pay such amount shall have been
accrued as a liability on the Final Business Balance Sheet.  

          (b)  As of the Effective Date, the Reinsurer shall be substituted for
and succeed to all of the rights and liabilities of the Company, under the
reinsurance agreements listed in SCHEDULE 7.1-B (the "Schedule 7.1-B
Reinsurance" and, together with the Schedule 7.1-A Reinsurance, the "Ceded
Reinsurance") and shall be recognized for all purposes as the "Company"
thereunder in substitution for the Company.  The Company shall transfer, set
over, assign and convey to Zenith all of its rights and obligations of any
nature whatsoever under the Schedule 7.1-B Reinsurance, including (i) amounts
held by or which may become due from assuming reinsurers with respect to any
reinsurance ceded by the Company to the reinsurer thereunder, and (ii) letters
of credit, trust funds and other security mechanisms outstanding for the benefit
of the Company pursuant to the terms of any of the Ceded Reinsurance.  Zenith
shall accept such conveyance, transfer and assignment of the Company's rights
under the Schedule 7.1-B Reinsurance and assumes all of the Company's
obligations under the Schedule 7.1-B Reinsurance existing on or arising after
the Effective Date.  The assignment and assumption of the Schedule 7.1-B
Reinsurance effected by this Section 7.1 shall be effective only if such
assignment (i) is permitted under the terms of such Schedule 7.1-B Reinsurance
or as otherwise consented to by the reinsurer thereunder, and (ii) shall
preserve fully the obligations of the reinsurers thereunder in respect of

                                     -7-

the Insurance Contracts.  If the Company's rights and obligations under any 
such Schedule 7.1-B Reinsurance are not assigned to and assumed by Zenith, 
(i) after the Effective Date, Zenith shall be responsible for the payment of 
all premiums and other considerations required to be paid by the Company in 
respect of any of the Schedule 7.1-B Reinsurance, (ii) all reinsurance 
recoveries attributable to any of the Schedule 7.1-B Reinsurance are assigned 
and shall accrue to the benefit of Zenith hereunder by operation of this 
Section 7.1 and shall, upon receipt thereof by the Company, be paid promptly 
thereby to Zenith upon and in accordance with its direction, and (iii) such 
assignment shall be effective at such time as the assignment may be effected 
while preserving fully the obligations of the reinsurer under the respective 
Schedule 7.1-B Reinsurance.  

          (c)  The Company shall reasonably cooperate with Zenith in causing
reinsurers under the Ceded Reinsurance to pay reinsurance recoveries to Zenith
after the Effective Date.

          Section 7.2  CEDED REINSURANCE COLLATERAL.  To the extent necessary to
effect any transfer or assignment pursuant to this Section 7.1 of any assumed
reinsurance, the Company hereby appoints Zenith as attorney-in-fact for the
Company to act for and on behalf of it with respect to letters of credit, trust
funds and other security mechanisms outstanding for the benefit of the Company
pursuant to the terms of any of the Ceded Reinsurance, and the Company shall
execute and deliver to Zenith such additional instruments as Zenith may
reasonably request to give effect to such appointment as attorney-in-fact, and
to provide appropriate evidence that the Company has assigned to Zenith all of
its rights under the Ceded Reinsurance with respect to any such letters of
credit, trust funds or other accounting mechanism.  Zenith shall use its
reasonable best efforts to the extent deemed reasonably necessary by Zenith, to
cause the reinsurers under the Ceded Reinsurance to provide replacement letters
of credit, trust funds or other security mechanisms, as applicable, naming
Zenith as the beneficiary thereof in amounts and with terms substantially
similar to those currently provided by such reinsurers for the benefit of the
Company.

defense, setoff or counterclaim with respect to, or amend, commute or terminate,
any Insurance Contract or Ceded Reinsurance without the prior written consent of
Zenith, except in accordance with the provisions of the indemnities referred to
in the following sentence.  The Company's sole and exclusive remedy with respect

representatives, may inspect, at the place where such records are located, any

hereunder if such delay, omission, error or failure is corrected within 20
Business Days of receipt of notice of such delay, omission, error or failure and
neither party shall have been prejudiced.

          Section 9.3   ADJUSTMENTS.  If the liability of the Company under any

of each month, Zenith will provide the Company with reports of activities under
this Agreement for the preceding month.  Such reports shall show any amounts due

premiums or other amounts due with respect to the Insurance Contracts.  The net
balance due either party, as indicated in the monthly report, shall be remitted
to the other party within 15 days of the delivery of said monthly report.  The
requirements of this Section 10.1 shall terminate if, for twelve consecutive
months, no amounts are reported as due either party with respect to the
Insurance Contracts; PROVIDED, such requirements shall be reinstated and shall
continue in effect for an additional twelve months if at any time following such
termination, any balance or amount becomes due either party under this
Agreement.   

          Section 10.2  FINANCIAL STATEMENT INFORMATION.  On or before the last
business day of each January, April, July and October, Zenith shall provide the
Company with a quarterly or annual report containing the financial, accounting

                                      INSOLVENCY

          Section 12.1  PAYMENTS BY ZENITH.  Zenith hereby agrees that all
amounts due under this Agreement with respect to all Quota Share Policies shall
be payable by Zenith on the basis of the liability of the Company under such
contracts, without diminution because of the insolvency, liquidation or
rehabilitation of the Company Insurance Subsidiary.  Zenith shall make payments
due hereunder with respect to Quota Share Policies directly to the Company or to
its conservator, receiver, liquidator or other statutory successor.

          Section 12.2  CLAIMS.  It is agreed that any conservator, receiver,
liquidator or statutory successor of the Company shall give prompt written
notice to Zenith of the pendency or submission of a claim under any Insurance
Contract.  With respect to any Insurance Contract, during the pendency of such
claim, Zenith may investigate such claim and interpose, at its own expense, in
the proceeding where such claim is to be adjudicated, any defense available to
the Company or its conservator, receiver, liquidator or statutory successor. 
The expense thus incurred by Zenith is chargeable against the Company as a part
of the expense of insolvency, liquidation or rehabilitation to the extent of a
proportionate share of the benefit which accrues to the Company solely as a
result of the defense undertaken by Zenith.  Where Zenith and other assuming
companies are involved in the same claim and a majority in interest elect to
interpose a defense to such claim, the expense shall be apportioned in
accordance with the terms of the insurance agreement as though such expense had
been incurred by the Company.

                     RIGHTS WITH RESPECT TO QUOTA SHARE POLICIES

          Section 14.1  SOLE BENEFICIARY.  Zenith's quota share reinsurance of
100% of the Insurance Liabilities of the Company with respect to any of the
Quota Share Policies is intended for the sole benefit of the parties to this
Agreement and shall not create any right on the part of any Policyholder,
insured, claimant or beneficiary under such Quota Share Policies against Zenith
or any legal relation between such Policyholders, insureds, claimants or
beneficiaries and Zenith.   


                                      ARTICLE XV

          Section 15.1   APPOINTMENT OF ARBITRATORS.  Any dispute or 
difference arising under this Agreement that cannot be resolved by agreement 
among the parties hereto shall be decided by arbitration in accordance with 
this Article XV.  Any such arbitration shall be conducted expeditiously and 
confidentially in accordance with the Commercial Arbitration Rules of the 
American Arbitration Association ("AAA") as such rules shall be in effect on 
the date of delivery of demand for arbitration.  Any such arbitration shall 
be heard and conducted in New York, New York.  Notwithstanding the rules of 
the AAA, the arbitration panel in any such arbitration shall consist of three 
persons who must be disinterested current or retired officers of insurance or 
reinsurance companies other than the parties to this Agreement or their 
Affiliates.  Within twenty days of delivery of any demand for arbitration 
hereunder, the Company and Zenith shall each appoint one arbitrator, and the 
two arbitrators so selected shall appoint the third arbitrator within twenty 
days of their appointment.  In the event the two selected arbitrators are 
unable to agree upon the selection of a third arbitrator after reasonable 
efforts, a panel of seven qualified persons shall be requested from the AAA.  
The parties shall alternately strike one person with the last remaining 
person being the third designated arbitrator; the party responding to the 
initial demand for arbitration shall have the first turn. Each party shall 
pay the fees of its own attorneys, expenses of witnesses and all other 
expenses connected with the presentation of such party's case.  One-half of 
any remaining costs of any arbitration, including the cost of the record or 
transcripts thereof, if any, administrative fees and all other fees involved 
shall be paid by Zenith, and the remaining one-half shall be paid by the 
Company.

party's financial statements.

          Section 15.4  SURVIVAL OF ARTICLE.  This Article XV shall survive
termination of this Agreement.

          Section 15.5  OTHER ACTIONS.  Submission of a matter to arbitration
shall be a condition precedent to any right to institute a proceeding at law or
in equity concerning such matter, except for injunctive or other provisional
relief pending the arbitration of a matter subject to arbitration pursuant to
this Agreement.  Subject to the foregoing, each party hereto consents to the non
exclusive jurisdiction of the United States District Court for the Southern
District of New York (the "Chosen Court") in respect of any claim arising out
of, related to or contemplated by this Agreement, (i) waives any objection to
laying venue in any such action or proceeding in the Chosen Court, (ii) waives

FOR IMMEDIATE RELEASE                             & Chief Financial Officer


              ZENITH NATIONAL CLOSES ITS PURCHASE OF ASSETS OF RISCORP


WOODLAND HILLS, CA, April 2, 1998  .  .  .  .  .  .  .  Zenith National 
Insurance Corp. (ZNT) announced today that its wholly-owned subsidiary, 
Zenith Insurance Company, closed its transaction to purchase certain assets 
of RISCORP, Inc. and its subsidiaries under an agreement previously announced 
on June 17, 1997.  The transaction is effective April 1, 1998. 

Under the transaction, Zenith acquired all the assets and assumed certain of 
the liabilities of RISCORP, Inc. and its subsidiaries related to the workers' 
compensation business, including inforce insurance business as well as the 
right to all new and renewal policies.  Zenith also purchased RISCORP's 
"First Call"(sm) managed care workers' compensation system.  

RISCORP will no longer engage in the workers' compensation or managed care 
businesses.

The purchase price, to be paid in cash, will be the difference between the 
book value of the assets purchased and the book value of the liabilities 
assumed by Zenith as of April 1, 1998.  The final purchase price is subject 
to audit and a dispute resolution process and cannot be determined at this 
time.  At closing, Zenith paid the minimum cash purchase price of $35 million 
and assumed $15 million in certain indebtedness of RISCORP, Inc.


                                                            Continued

Stanley R. Zax, Chairman and President commented, "We are delighted to expand 
our Southeast operations with the closing of the purchase of the assets and 
inforce business of RISCORP.  The consummation of this strategic acquisition 
provides expanded geographic diversification in our workers' compensation 
business and adds state-of-the-art managed care and agent Internet 
communication capabilities to our operations.  We welcome all of RISCORP's 
policyholders, agents, claimants and employees to the Zenith Family and we 
are excited about renewing and energizing our new partners with a goal of a 
mutually beneficial and profitable relationship."
