                                    ARTICLE I

                         AGREEMENT TO PURCHASE AND SELL
                              OWNERSHIP INTERESTS

                  1.1 Agreement to Purchase and Sell Ownership Interests. On the
basis of the representations and warranties set forth in Articles II, III and IV
of this Agreement and subject to the terms and conditions of this Agreement,

Closing (as defined in Section 10.2 hereof) provided for herein, such
Shareholder's Ownership Interests for consideration equal to such Shareholder's
Percentage of the aggregate Consideration specified in Section 1.2.
"Shareholder's Percentage" means, for each Shareholder, as to each component of
the Consideration, the percentage set forth under the "Shareholder's Percentage"
column opposite such Shareholder's name on Exhibit A hereto.


<PAGE>   9
                                      -3-



                  1.2  Consideration.

                  (a) At the Closing, Delphi shall pay to the Shareholders,
severally according to their Shareholder's Percentages, an amount in cash equal
in the aggregate to the pre-tax cash flow (determined in accordance with the
procedures set forth in Exhibit B hereto) ("Pre-tax Cash Flow") generated by the
Companies during the period from January 1, 1998 through June 30, 1998 (minus
any amounts of Pre-tax Cash Flow attributable to such period previously
distributed by either of the Companies to the Shareholders or affiliates thereof
during 1998 ("Prior Distributions")). On or before December 31, 1998, Delphi
shall pay to the Shareholders, severally according to their Shareholder's
Percentages, an amount in cash equal in the aggregate to the Pre-tax Cash Flow
generated by the Companies during the period from July 1, 1998 through September
30, 1998 (minus any Prior Distributions); provided, however, that to the extent
the aggregate of the Prior Distributions exceeds Pre-tax Cash Flow for the
period from January 1, 1998 through September 30, 1998 determined in accordance
with the provisions of Exhibit B ("Excess Distributions"), Delphi shall promptly
notify the Shareholders of its determination and the Shareholders shall repay,
on or before December 31, 1998, such Excess Distributions severally according to
their Shareholder's Percentages, in cash, to Delphi.

                  (b) As further consideration for the purchase of the Ownership
Interests by Delphi (the "Additional Consideration" and collectively with the
payments described in the preceding paragraph, the "Consideration"), the
following amounts will be payable by Delphi to each of the Shareholders
severally according to their Shareholder's Percentages; provided, however, that
any Excess Distributions made to a particular Shareholder, owed to Delphi by
such Shareholder and not fully repaid in accordance with Section 1.2(a) as of
the payment date of any Additional Consideration shall be deducted from such
Shareholder's Additional Consideration payment:

                    (i) an amount equal in the aggregate to 1.0 times Pre-tax
         Cash Flow generated by the Companies during the period from October 1,
         1998 through December 31, 1998 will be payable as Additional
         Consideration within three months after the end of such period,
         provided, however, that to 

<PAGE>   10
                                      -4-


         the extent Pre-tax Cash Flow for such period exceeds $7,100,000, such
         excess will be multiplied instead by 2.0;

                   (ii) an amount equal in the aggregate to 2.0 times Pre-tax
         Cash Flow generated by the Companies during the period from January 1,
         1999 through December 31, 1999 will be payable as Additional
         Consideration within three months after the end of such period,
         provided, however, that the portion of Pre-tax Cash Flow for such
         period equal to the amount, if any, by which Pre-tax Cash Flow for the
         period described in paragraph (i) above is less than $7,100,000 will be
         multiplied instead by 1.0;

                  (iii) an amount equal in the aggregate to 1.75 times Pre-tax
         Cash Flow generated by the Companies during the period from January 1,
         2000 through December 31, 2000 will be payable as Additional
         Consideration within three months after the end of such period;

                   (iv) an amount equal in the aggregate to 1.5 times Pre-tax
         Cash Flow generated by the Companies during the period from January 1,
         2001 through December 31, 2001 will be payable as Additional
         Consideration within three months after the end of such period; and

                    (v) an amount equal in the aggregate to 1.25 times Pre-tax
         Cash Flow generated by the Companies during the period from January 1,
         2002 through December 31, 2002 will be payable as Additional
         Consideration within three months after the end of such period.

                  For the avoidance of doubt, the exact multiples to be applied
to Pre-tax Cash Flow for each period for each Shareholder (i.e., the multiples
set forth in clauses (i)-(v) above times each Shareholder's Percentage) are set
forth opposite such Shareholder's name on Exhibit C hereto.

                  Each such payment of Additional Consideration shall be payable
to each Shareholder 60% in cash and 40% in Class A Common Stock, par value $.01
per share (the "Delphi Common Stock"), of Delphi (such payments in cash to the
Shareholders, 

<PAGE>   11
                                      -5-


the "Cash Consideration" and such payments of stock to the Shareholders, the
"Stock Consideration"), provided, however, that if the amount of the Cash
Consideration that would otherwise be paid pursuant to paragraph (i) above is
less than the amount of the aggregate Federal, state and local ordinary income
tax liability that will arise on the part of the Shareholders due to the Section
338(h)(10) election made pursuant to Section 6.9(a), the portion of the
Additional Consideration for such period to be paid in cash to the Shareholders
shall be adjusted upward, and the proportion thereof payable in Delphi Common
Stock correspondingly adjusted downward, pro rata in each case among the
Shareholders according to their Shareholder's Percentages, such that the
aggregate amount of such Additional Consideration paid in cash to the
Shareholders shall be equal to the lesser of such aggregate tax liability or 75%
of the aggregate Additional Consideration payment for such period.

                  (c) The number of shares of Delphi Common Stock to be issued
in payment of the Stock Consideration will be determined based on the average
per share closing price thereof as reported on the principal national securities
exchange or inter-dealer quotation system on which the Delphi Common Stock is
then listed for the last 10 trading days of the period with respect to which
such payment of Stock Consideration is being made (the "Market Price"), adjusted
as appropriate for any stock dividend with respect to which the record date
occurs during such 10 day period.

                  (d) Notwithstanding the provisions of paragraphs (b) and (c)
above, in the event that, at the time a payment of Additional Consideration is
to be made, (i) the Delphi Common Stock is not listed on any national securities
exchange or inter-dealer quotation system, then Delphi will have the option to
elect to pay and the Shareholders will have the option to elect to receive such
Additional Consideration payment


<PAGE>   12
                                      -6-



100% in cash in either case upon written notice to the other party and/or (ii)
there has occurred a Change of Control (as hereinafter defined) of Delphi, then
the Shareholders will have the option to elect to receive such Additional
Consideration payment 100% in cash, upon written notice by such Shareholder to
Delphi; provided, that in the event of a Change of Control wherein 50% or more
of the consideration to be received by the holders of Delphi Common Stock
consists of publicly-traded voting common equity of the surviving entity, then
the Shareholders will not have the option to receive such payment 100% in cash
but will instead be entitled to receive such publicly-traded common equity in
payment of the Stock Consideration. "Change of Control" shall mean any merger,
consolidation or other acquisition of Delphi pursuant to which Delphi is not the
surviving entity or pursuant to which the Delphi Common Stock would be converted
into cash, other securities or other property, other than any such transaction
in which (i) members of Delphi's Board of Directors immediately prior to such
transaction will initially constitute at least a majority of the Board of
Directors of the surviving entity, (ii) the holders of Delphi Common Stock
immediately prior to such transaction will initially hold at least a majority of
the outstanding shares of voting common equity of the surviving entity, or (iii)
the management of Delphi immediately prior to such transaction will continue to
manage, directly or indirectly, the business and operations of the surviving
entity.

                  (e) Notwithstanding any other provision of this Agreement,
neither certificates nor scrip for fractional shares of Delphi Common Stock
shall be issued as Stock Consideration. Each Shareholder who otherwise would
have been entitled to a fraction of a share of Delphi Common Stock shall receive
in lieu thereof cash (without interest) in an amount determined by multiplying
the fractional share interest to which such Shareholder would otherwise be
entitled by the Market Price for such payment of Stock Consideration. No such
Shareholder shall be entitled to dividends, voting rights or any other rights in
respect of any fractional share.

                  1.3 Purchase Price Allocation. Delphi and the Shareholders
agree that a portion of the Consideration equal to the net worth of
Intermediaries (as determined in accordance with GAAP) on September 30, 1998
shall be allocated to the purchase of Intermediaries with the remainder of the
Consideration 

<PAGE>   13
                                      -7-



allocated to the purchase of Unicover. Unless otherwise required by law, no
party shall take any position inconsistent with the foregoing allocation or
inconsistent with Sections 6.9(a) or (b) hereof on any Tax Return (as defined in
Section 3.17 hereof) or for any other Tax purpose.

                  1.4  Certificates.

                  (a) At the Closing, each Shareholder shall deliver to Delphi
the certificates (the "Certificates") representing such Shareholder's Ownership
Interests, accompanied by blank stock or other similar powers duly executed by
such Shareholder and with all necessary transfer tax and other revenue stamps,
acquired at such Shareholder's expense, affixed and canceled. Each Shareholder
shall promptly cure any deficiencies with respect to the stock or other similar
powers accompanying the Certificates representing such Shareholder's Ownership
Interests.

                  (b) The Delphi Common Stock to be distributed as Stock
Consideration will be stamped or imprinted with a legend in substantially the
following form:

                  "THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE
         SECURITIES LAWS OF ANY STATE, AND MAY NOT BE DISTRIBUTED, SOLD,
         TRANSFERRED, ASSIGNED, HYPOTHECATED OR OFFERED UNLESS THERE IS IN
         EFFECT A REGISTRATION STATEMENT UNDER SUCH ACT AND LAWS COVERING SUCH
         SECURITIES OR AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF SUCH
         ACT IS AVAILABLE AND, IF REQUESTED, AN OPINION OF COUNSEL FOR THE
         HOLDER OF THESE SECURITIES REASONABLY SATISFACTORY TO THE ISSUER IS
         PROVIDED.

                  "THE SECURITIES EVIDENCED BY THIS CERTIFICATE ARE ALSO SUBJECT
         TO RESTRICTIONS ON RESALE CONTAINED IN THAT CERTAIN STOCK PURCHASE
         AGREEMENT, DATED AS OF OCTOBER 1, 1998, A COPY OF WHICH IS AVAILABLE
         FROM THE SECRETARY OF THE ISSUER."

                                   ARTICLE II

               REPRESENTATIONS AND WARRANTIES OF THE SHAREHOLDERS

                  Each Shareholder hereby represents and warrants, severally and
not jointly, to Delphi as follows:

                  2.1 Title to Ownership Interests. Each such Shareholder is the
true and lawful owner, of record and beneficially, of the Ownership Interests
set forth opposite the name of such Shareholder in each of the columns under the
heading "Ownership Interests" on Exhibit A hereto. At the Closing, each
Shareholder will validly transfer the Ownership Interests owned by him free and
clear of all liens, security interests, pledges, assessments, charges, adverse
claims, leases, licenses, restrictions and other encumbrances (collectively,
"Liens"). Other than the rights and obligations arising under this Agreement,
none of such Ownership Interests are subject to any rights of any other person
to acquire the same. Except as disclosed in Section 2.1 of the Disclosure
Schedules, none of such Ownership Interests are subject to any restrictions on
transfer thereof, except for such restrictions as may be imposed by applicable
federal and state securities laws.

                  2.2 Authority Relative to Agreements. Each such Shareholder
has full power and authority to enter into this Agreement, a Non-competition
Agreement, the Option Agreements and, if applicable, an Employment Agreement, a
Letter Agreement and/or a Side Letter (this Agreement, the Non-competition
Agreements, the Option Agreements, the Employment Agreements, the Letter
Agreements and the Side Letters are hereinafter sometimes referred to
collectively as the "Transaction Documents") and to perform his obligations
hereunder and thereunder. The Transaction Documents have been duly executed and
delivered by such Shareholder party thereto; and the Transaction Documents
constitute, assuming the due authorization, execution and delivery thereof by
Delphi, the legal, valid and binding obligation of such Shareholder party
thereto, enforceable against each of them in accordance with its terms, except
(i) as enforcement thereof may be limited by bankruptcy, insolvency,
reorganization, moratorium, fraudulent conveyance, or 


<PAGE>   15
                                      -9-


other similar laws affecting the enforcement of creditors' rights generally, and
(ii) as enforcement thereof is subject to general principles of equity
(regardless of whether enforcement is considered in a proceeding at law or in
equity). Except as disclosed in Section 2.2 of the Disclosure Schedule, the
execution and delivery of the Transaction Documents by each of the Shareholders
party thereto and performance of his obligations hereunder and thereunder will
not conflict with or result in a breach, default (or an event which, with notice
or lapse of time or both, would constitute a default) or violation of any of the
terms, provisions or conditions of any agreement, document or instrument, or any
judgment, decree, court order, statute, regulation, ordinance or law to which
such Shareholder is subject. Except as contemplated by Section 7.1(b) hereof, no
permit, authorization, consent or approval of, or filing with or notification
to, any court or public body or authority or expiration of any governmentally
imposed waiting period, and no authorization, consent, or approval of, or
release by, any other third party, is necessary for the execution and delivery
of the Transaction Documents and the consummation by such Shareholder of the
sale of the Ownership Interests as contemplated by this Agreement and the
performance of his respective obligations hereunder and thereunder.

                  2.3  Securities Matters.

                  (a) Such Shareholder (a) has such knowledge, sophistication
and experience in business and financial matters that he is capable of
evaluating the merits and risks of an investment in the shares of Delphi Common
Stock, (b) fully understands the nature, scope and duration of the limitations
on transfer contained herein and under applicable law, and (c) can bear the
economic risk of an investment in the shares of Delphi Common Stock and can
afford a complete loss of such investment.

                  (b) Such Shareholder is acquiring the shares of Delphi Common
Stock comprising the Stock Consideration for his own account and not with a
present view to or for distributing or reselling such shares (or any portion
thereof). Such Shareholder has no contract, undertaking, agreement or
arrangement, written or oral, with any other person to sell, transfer or 


<PAGE>   16
                                      -10-


grant participation in any shares of Delphi Common Stock to be acquired by such
Shareholder pursuant to this Agreement.

                  (c) Such Shareholder acknowledges receipt of copies of
Delphi's Annual Report on Form 10-K for the fiscal year ended December 31, 1997,
its proxy statement relating to its 1998 annual meeting of stockholders and its
Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 1998
and June 30, 1998, each as filed by the Company with the Securities and Exchange
Commission ("SEC") (collectively, the "Delphi SEC Reports") and further
acknowledges that he has been afforded (i) the opportunity to ask such questions
as he has deemed necessary of, and to receive answers from, representatives of
Delphi concerning the terms and conditions of the payment of the Stock
Consideration and the merits and risks of investing in the Stock Consideration;
(ii) access to information about Delphi and Delphi's financial condition,
results of operations, business, properties, management and prospects sufficient
to enable such Shareholder to evaluate his investment; and (iii) the opportunity
to obtain such additional information which Delphi possesses or can acquire
without unreasonable effort or expense that is necessary to make an informed
investment decision with respect to the investment and to verify the accuracy
and completeness of the information contained in the Delphi SEC Reports.

                  (d) Such Shareholder understands and acknowledges that (i) the
shares of Delphi Common Stock comprising the Stock Consideration are being
offered and sold to him without registration under the Securities Act in a
private placement that is exempt from registration provisions of the Securities
Act of 1933, as amended (the "Securities Act"), under Section 4(2) of the
Securities Act or Regulation D promulgated thereunder and (ii) the availability
of such exemption depends in part on, and Delphi will rely upon, the accuracy
and truthfulness of the foregoing representations.

                  2.4 FIRPTA Affidavit. Such Shareholder has provided an
affidavit to Delphi stating, under penalty of perjury, such Shareholder's United
States taxpayer identification number and 

<PAGE>   17
                                      -11-



that such Shareholder is not a foreign person (within the meaning of Section
1445(b)(2) of the Code).


                                   ARTICLE III

             REPRESENTATIONS AND WARRANTIES OF THE COMPANIES AND THE
                                  SHAREHOLDERS

                  Each of the Companies and each of the Shareholders, jointly
and severally, represent and warrant to Delphi as follows:

                  3.1 Organization and Qualification. Each of the Companies is a
corporation or limited liability company duly organized, validly existing and in
good standing under the laws of the jurisdiction of its incorporation or
organization and has all requisite corporate or other power and authority to
own, lease and operate its properties and to carry on its business as now being
conducted. Each of the Companies is duly qualified as a foreign corporation or
limited liability company to do business, as the case may be, and is in good
standing, in each jurisdiction where the character of its properties owned or
leased or the nature of its activities makes such qualification necessary,
except where the failures to be so qualified or in good standing would not,
individually or in the aggregate, have a material adverse effect on the
business, operations, condition (financial or other) or assets of the Companies,
taken as a whole (a "Company Material Adverse Effect"). Section 3.1 of the
Disclosure Schedule lists all of the jurisdictions in which the Companies or any
present employee thereof holds active licenses and permits or authorizations to
transact the Companies' business (the "Licenses") and indicates the type of each
License and the name of each such employee. No such License is the subject of
any administrative proceeding for suspension or revocation or any similar
proceedings which would, if decided against either of the Companies or the
relevant employee, materially and adversely affect such License; there is no
sustainable basis for such a suspension or revocation which would, individually
or in the aggregate, have a Company Material Adverse Effect; and neither of the
Companies nor 


<PAGE>   18
                                      -12-



any of the Shareholders has received notice of any pending or threatened
suspension or revocation of any license or permit from any licensing authority.
Section 3.1 of the Disclosure Schedule sets forth, with respect to the
Companies, all jurisdictions in which they are qualified or otherwise licensed
as a foreign corporation or other entity to do business. Neither of the
Companies is in violation of any of the provisions of its articles of
incorporation, by-laws or other organizational documents. Each of the Companies
has delivered to Delphi accurate and complete copies of the articles of
incorporation and by-laws or other organizational documents, as currently in
effect, of such Company.

                  3.2 No Subsidiaries. There are no direct or indirect
subsidiaries of either of the Companies. The Companies do not directly or
indirectly own any interest in any corporation, partnership, limited liability
company, joint venture or other business association or entity.

                  3.3 Capitalization. The authorized capital stock of Unicover
consists of 1,000 shares of common stock, par value $1.00 per share, 102.564 of
which are issued and outstanding, fully paid and nonassessable and free of
preemptive rights. The capitalization of Intermediaries is $100 of membership
interests, all of which are issued and outstanding, fully paid and nonassessable
and free of preemptive rights. Except as disclosed in Section 3.3 of the
Disclosure Schedule, no Company is a party to any agreement or understanding,
oral or written, which (a) grants an option or other right to acquire any of the
Ownership Interests or any other equitable interest in either Company, (b)
grants a right of first refusal or other such similar right upon the sale of any
of the Ownership Interests, or (c) restricts or affects the voting rights of any
of the Ownership Interests.

                  3.4 Authority Relative to Agreements. Each of the Companies
has full corporate or other power and authority to execute and deliver the
Transaction Documents to the extent a party thereto and to consummate the
transactions contemplated thereby. The execution and delivery of the Transaction
Documents to which it is a party and the consummation of the transactions


<PAGE>   19
                                      -13-


contemplated thereby have been duly and validly authorized by the Boards of
Directors or equivalent governing body of each of the Companies and consented to
and approved by each Shareholder, and no other corporate or other proceedings on
the part of the Companies are necessary to authorize the Transaction Documents
to which they are parties or to consummate the transactions contemplated
thereby. The Transaction Documents to which it is a party have been duly and
validly executed and delivered by each of the Companies party to such
Transaction Documents and, assuming the due authorization, execution and
delivery thereof by Delphi, constitute the legal, valid and binding agreement of
each of the Companies, enforceable against each of the Companies in accordance
with its terms, except (i) as enforcement thereof may be limited by bankruptcy,
insolvency, reorganization, moratorium, fraudulent conveyance, or other similar
laws affecting the enforcement of creditors' rights generally, and (ii) as
enforcement thereof is subject to general principles of equity (regardless of
whether enforcement is considered in a proceeding at law or in equity).

                  3.5  No Violations, etc.

                  (a) Except as disclosed in Section 3.5(a) of the Disclosure
Schedule, neither the execution and delivery of the Transaction Documents by
each of the Companies party thereto nor the consummation of transactions
contemplated thereby nor compliance by each of the Companies party thereto with
any of the provisions hereof will (i) violate, conflict with, or result in a
breach of any provision of, or constitute a default (or an event which, with
notice or lapse of time or both, would constitute a default) under, or result in
the termination or suspension of, or accelerate the performance required by, or
result in a right of termination or acceleration under, or result in the
creation of any Lien upon any of the properties or assets of either of the
Companies under, any of the terms, conditions or provisions of (x) its charter,
by-laws or other organizational documents, (y) any note, bond, mortgage,
indenture or deed of trust, or (z) any license, lease, agreement or other
instrument or obligation to which either of the Companies is a party or to which
either of them or their respective properties or assets may be subject, or (ii)
violate any judgment, ruling, 


<PAGE>   20
                                      -14-


order, writ, injunction, decree, statute, rule or regulation applicable to
either of the Companies or their respective properties or assets.

                  (b) Except as contemplated by Section 7.1(b) hereof, no filing

         covenants contained in Section 5.1 hereof as if such covenants applied
         beginning June 30, 1998 (without giving effect to the provisions
         relating to the consent of Delphi); and

                  (g) there has not been any agreement by either of the

on the First Interim Balance Sheets except for property since sold or otherwise
disposed of in the ordinary course of business and consistent with past
practice. No such personal property is subject to claims, liens or encumbrances,

nor any trustee, administrator, other fiduciary or any other "party in interest"
or "disqualified person" with respect to the Pension Benefit Plans or Welfare
Plans, has engaged in a "prohibited transaction" (as such term is defined in
Section 4975 of the Code or Section 406 of ERISA) that could result in a tax or
penalty on either of the Companies under Section 4975 of the Code or Section
502(i) of ERISA, except any such event that would not, individually and in the
aggregate, either impair the Companies' ability to consummate the transactions
contemplated hereby or have a Material Adverse Effect.

                  (g) Neither of the Companies or any of their ERISA Affiliates
maintain or contribute to, nor have they ever maintained or contributed to, any

United States.

                  (j) Except as disclosed in Section 3.18 of the Disclosure

impair the Companies' ability to consummate the transactions contemplated hereby
or have a Material Adverse Effect.

                  (l) No liability under any Pension Benefit or Welfare Plan has
been funded nor has any such obligation been satisfied with the purchase of a
contract from an insurance company as to which either of the Companies has
received notice that such insurance company is in rehabilitation or a comparable
proceeding.

                  (m) Except as otherwise specifically provided by this
Agreement or the Transaction Documents, the consummation of the transactions
contemplated by this Agreement will not result in an increase in the amount of
compensation or benefits or accelerate the vesting or timing of payment of any
benefits or compensation payable to or in respect of any employee of either of
the Companies.

                                      -29-


                  (n) The consummation of the transactions contemplated by this
Agreement will not result in or satisfy a condition to the payment of
compensation that would, in combination with any other payment, result in an
"excess parachute payment" within the meaning of Section 280G(b) of the Code.

                  (o) There is no plan, program, policy, arrangement or

                                   ARTICLE IV

                        REPRESENTATIONS AND WARRANTIES OF
                                     DELPHI

                  Delphi represents and warrants to the Company that:

                  4.1 Organization and Qualification. Delphi is a corporation
duly organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation and has all requisite corporate power and
authority to own, lease and operate its properties and to carry on its business
as now being conducted. Delphi is duly qualified as a foreign corporation to do
business, and is in good standing, in each jurisdiction 

<PAGE>   41
                                      -35-


where the character of its properties owned or leased or the nature of its
activities makes such qualification necessary, except where the failures to be
so qualified or in good standing which would not, individually or in the
aggregate, have a material adverse effect on the business, operations or
condition (financial or otherwise) or assets of Delphi and its subsidiaries
taken as a whole (a "Delphi Material Adverse Effect"). Delphi is not in
violation of any of the provisions of its certificate or articles of
incorporation or organization (or other applicable charter document) or by-laws.

                  4.2 Authority Relative to Agreements. Delphi has full
corporate power and authority to execute and deliver the Transaction Documents
and to consummate the transactions contemplated thereby. The execution and
delivery of the Transaction Documents and the consummation of the transactions
contemplated thereby have been duly and validly authorized by the Board of
Directors of Delphi and no other corporate proceedings on the part of Delphi are
necessary to authorize the Transaction Documents or to consummate the
transactions contemplated thereby. The Transaction Documents have been validly
executed and delivered by Delphi and, assuming the due authorization, execution
and delivery thereof by each of the Companies and the Shareholders party
thereto, constitutes the legal, valid and binding agreement of Delphi,
enforceable against Delphi in accordance with its terms, except (i) as
enforcement thereof may be limited by bankruptcy, insolvency, reorganization,
moratorium, fraudulent conveyance, or other similar laws affecting the
enforcement of creditors' rights generally, and (ii) as enforcement thereof is
subject to general principles of equity (regardless of whether enforcement is
considered in a proceeding at law or in equity).

                  4.3  No Violations, Etc.

                  (a) Assuming the accuracy of the representations set forth in
Article II, neither the execution and delivery of this Agreement by Delphi nor
the consummation of transactions contemplated hereby nor compliance by Delphi
with any of the provisions hereof will (i) violate, conflict with, or result in
a breach of any provision of, or constitute a default (or an 

<PAGE>   42
                                      -36-


event which, with notice or lapse of time or both, would constitute a default)
under, or result in the termination or suspension of, or accelerate the
performance required by, or result in a right of termination or acceleration
under, or result in the creation of any Lien, upon any of the properties or
assets of Delphi or any of Delphi's subsidiaries under, any of the terms,
conditions or provisions of (x) their respective charters or by-laws, (y) any
material note, bond, mortgage, indenture or deed of trust, or (z) any material
license, lease, agreement or other instrument or obligation, to which Delphi or
any such subsidiary is a party or to which they or any of their respective
properties or assets may be subject, or (ii) subject to compliance with the
statutes and regulations referred to in the next paragraph, violate any
judgment, ruling, order, writ, injunction, decree, statute, rule or regulation
applicable to Delphi or any of Delphi's subsidiaries or any of their respective
properties or assets, except, in the case of clauses (i)(y), (i)(z) and clause
(ii) above, for such violations, conflicts, breaches, defaults, terminations,
suspensions, accelerations, rights of termination or acceleration or creations
of liens, security interests, charges or encumbrances which would not,
individually or in the aggregate, either have a Delphi Material Adverse Effect
or materially impair the consummation of the transactions contemplated hereby.

                  (b) Except as contemplated by Section 7.1(b) hereof, no filing
or registration with, notification to and no permit, authorization, consent or
approval of any governmental entity is required by Delphi or any of Delphi's
subsidiaries in connection with the execution and delivery of this Agreement or
the consummation by Delphi of the transactions contemplated hereby, except such
filings, registrations, notifications, permits, authorizations, consents or
approvals the failure of which to be obtained, made or given would not,
individually or in the aggregate, materially impair the consummation of the
transactions contemplated hereby.

                  4.4 Investment. Delphi is acquiring the Ownership Interests
solely for investment purposes, for its own account and not with a present view
towards any distribution that would 

<PAGE>   43
                                      -37-


violate the Securities Act or applicable state securities laws of any state;
Delphi understands that the Ownership Interests have not been registered under
the Securities Act or the securities laws of any state and must be held
indefinitely unless subsequently registered under the Securities Act and
applicable state securities laws or unless an exemption from such registration
becomes or is available.

                  4.5 Sophisticated Purchaser. Delphi acknowledges that it can
bear the economic risk of its purchase of the Ownership Interests and has such
knowledge and experience in financial and business matters that it is capable of
evaluating the materials provided by the Companies.

                  4.6 Due Diligence. Delphi has made its own independent
examination, investigation, analysis and evaluation of the Companies. Delphi has
had the opportunity to visit the Companies and meet with its officers and
representatives to discuss the business, assets, liabilities and financial
condition of the Companies. Delphi has been furnished and has reviewed to its
satisfaction the documents referred to in this Agreement and the Disclosure
Schedule. Delphi acknowledges that: (a) subject to the accuracy of the
representations and warranties made by the Companies and the Shareholders, all
materials and financial and other information requested by Delphi have been
provided to Delphi and (b) it has been afforded the opportunity to obtain
additional information necessary to verify the accuracy of the representations,
warranties and information in this Agreement and the Disclosure Schedule or
otherwise provided to it.

                  4.7 Litigation. Except as set forth in the Delphi SEC Reports,
each as filed by the Company with the SEC, there is no (i) claim, action, suit
or proceeding pending or, to the knowledge of Delphi or any of its subsidiaries,
threatened against or relating to Delphi or any of its subsidiaries before any
court or governmental or regulatory authority or body or arbitration tribunal,
or (ii) outstanding judgment, order, writ, injunction or decree, or application,
request or motion therefor, of any court, governmental agency or arbitration
tribunal 

<PAGE>   44
                                      -38-


in a proceeding to which Delphi, any subsidiary of Delphi or any of their
respective assets was or is a party except, in the case of clauses (i) and (ii)
above, such as would not, individually or in the aggregate, materially impair
Delphi's ability to consummate the transactions contemplated hereby.

                  4.8 Finders or Brokers None of Delphi, the subsidiaries of
Delphi, the Board of Directors of Delphi or any member of the Board of Directors
of Delphi has employed any investment banker, broker, finder or intermediary in
connection with the transaction contemplated hereby who might be entitled to a
fee or any commission in connection with the transactions contemplated hereby.

                  4.9 Regulatory Matters. Delphi has not taken nor agreed to
take any action, and to the best of its knowledge there is no fact or
circumstance, that would materially impede or delay receipt of any approval
referred to in Section 7.1(b) or the consummation of the transactions
contemplated by this Agreement.

         agreed to in writing by Delphi or as set forth in the Schedules

         this Agreement to the Closing, each of the Companies will conduct its
         operations according to its ordinary course of business consistent with

         preserve intact its business organization, to keep available the
         services of its current officers and

         key employees and to maintain satisfactory relationships with
         customers, clients, cedents, brokers, pool members, facility
         participants, fronting companies, retrocessionaires and others having
         business relationships with it and will take no action that is
         reasonably likely to adversely affect the ability of the parties to
         consummate the transactions contemplated by this Agreement.

                  (b) Without limiting the generality of the foregoing, prior to
         the Closing, neither of the Companies will, without the prior written
         consent of Delphi:

                  or ownership interests or any securities convertible into
                  shares of any class of its capital stock or ownership
                  interests, including the filing or processing of a
                  registration statement under the Securities Act in connection
                  with an initial public offering;

                          (iii) split, combine or reclassify any shares of its

                  thereof) in respect of its capital stock or ownership
                  interests or purchase, redeem or otherwise acquire any shares
                  of its capital stock or ownership interests, except as
                  otherwise expressly provided in this Agreement;

                           (iv) (A) create, incur, assume, maintain or permit to

Closing Date, as determined in accordance with GAAP, shall be allocated to
goodwill, going concern value, and other intangible assets described in Section
197(d)(1) of the Code, as mutually determined by Delphi and Unicover. Unless
otherwise required by law, Delphi and the Shareholders shall not take any
position inconsistent with the Initial Purchase Price Allocation and the Revised

income taxes that are imposed under any New Jersey or Illinois law (including,
without limitation, the Illinois Personal Property Tax Replacement Income Tax)
that is similar or corresponds to Sections 1374 or 1375 of the Code, shall be
borne by Delphi. All other state, local and foreign corporate income taxes
imposed on Unicover as a result of the foregoing Section

shall be borne 50% by Delphi and 50% by the Shareholders. All federal, state,
local or foreign taxes imposed on the Shareholders in their capacity as
shareholders of Unicover in connection with the foregoing Section 338(h)(10)
election (or any similar election under state, local or foreign law) and any
federal, state, local or foreign corporate income taxes imposed on Unicover
pursuant to Sections 1374 and 1375 of the Code (or any similar provision of any

the Shareholders.

                  (b) Section 754 Election. The Shareholders shall cause
Intermediaries to make an election pursuant to Section 754 of the Code (and any
similar provision of state, local or foreign law) with respect to the sale of
the ownership interests in Intermediaries pursuant to this Agreement. Any
allocation required to be made pursuant to Section 755 of the Code in connection
with such election(s) shall be made as determined by Delphi.

                  (c) Transfer Taxes. Any real estate transfer or other transfer
taxes arising in connection with the sale of Ownership Interests contemplated by
this Agreement shall be borne by the Shareholders.

                  (d) Pre-Closing Tax Refunds of Unicover. Any refunds or
overpayments of Taxes of Unicover for any taxable period ending on or prior to
the Closing Date or that are attributable to the period from January 1, 1998
through the Closing Date that are received by, or otherwise applied for the
benefit of, Delphi shall be forwarded to the Shareholders; provided, however,
that Delphi shall have no obligation to pursue any such refunds or overpayments.

                  (e) Mutual Cooperation. Delphi and the Shareholders will
provide each other with such assistance as may reasonably be requested by either
of them in connection with the preparation 

<PAGE>   55
                                      -49-


of any Tax Return or amendment thereto, any audit or other examination by any
taxing authority or any judicial or administrative proceeding relating to Taxes.
The party requesting assistance hereunder shall reimburse the other party only
for expenses incurred to third parties in providing such assistance.

                  (f) Delphi Tax Covenant. Delphi covenants that, without the
prior consent of the Shareholders, it will not cause or permit any of the
Companies, except as otherwise required by law or regulation or pursuant to any
audit by any taxing authority, to make or change any tax election of a Company
(except for the elections contemplated in this Section 6.9 or any other election
required or expressly permitted elsewhere in this Agreement or the other
Transaction Documents), amend any Tax Return of a Company or take any tax
position on any Tax Return of a Company (other than a position based on any
allocation contemplated by Section 6.9(a) hereof or a position required or
permitted elsewhere in this Agreement or the other Transaction Documents), or
take any action or enter into any transaction on or after the Closing Date
(except as otherwise expressly required or expressly permitted elsewhere in this
Agreement or in the other Transaction Documents) that will result in any tax
liability of such Company or the Shareholders in respect of any tax period of
such Company ending prior to Closing. Delphi agrees that the Shareholders are to
have no liability for any pre-closing tax of a Company or its Shareholders
resulting from any action prohibited by the preceding sentence, that is taken by
Delphi or any of the Companies on or after the Closing Date and agrees to
indemnify and hold harmless the Shareholders against any such pre-closing tax of
a Company or its Shareholders (together with any interest, penalty, addition to
tax or additional amount) and any costs and expenses directly related thereto
(including, without limitation, reasonable expenses of investigation and
reasonable attorney's fees and expenses). Any indemnity payment made pursuant to
the preceding sentence of this Section 6.9(f) shall be reduced by the net tax
benefit, if any, realized by the Shareholders (directly or indirectly through
the Company) after taking into account all deductions, increased tax basis and
income resulting 

<PAGE>   56
                                      -50-


from the event giving rise to such indemnity payment and the receipt of such
indemnity payment.

                  6.10  Transfer Restrictions.

                  (a) Each Shareholder agrees that it will not sell, offer to
sell, pledge, hypothecate, transfer or otherwise dispose of ("transfer") any of
its Ownership Interests except to Delphi or a subsidiary of Delphi in accordance
with this Agreement.

                  (b) For a period of three (3) years after each payment of
Stock Consideration pursuant to Section 1.2(b) hereof (each such payment a
"Stock Consideration Payment" and each such three-year period a "Three-Year
Lock-Up Period"), each Management Shareholder shall not transfer any of the
shares of Delphi Common Stock received by such Management Shareholder as part of
such Stock Consideration Payment, except for (i) transfers by a Management
Shareholder upon the death of such Management Shareholder by will or pursuant to
the laws of descent or distribution, (ii) transfers to a Permissible Transferee
(as hereinafter defined), or (iii) transfers in compliance with the applicable
provisions of Rules 144 and 145 under the Securities Act, as amended from time
to time, in an amount not to exceed twenty-five percent (25%) of the number of
shares of Delphi Common Stock issued to such Management Shareholder as part of
each Stock Consideration Payment. For purposes of this Section 6.10,
"Permissible Transferee" shall mean, with respect to each Shareholder, (i) any
other Shareholder, (ii) any spouse, child or grandchild or spouse of a child or
grandchild of such Shareholder (a "Family Member"), or (iii) any trust for the
benefit of such Shareholder or Family Member of such Shareholder.

                  (c) For a period of two (2) years after each Stock
Consideration Payment (each such two-year period a "Two-Year Lock-Up Period"),
each Non-Management Shareholder shall not transfer any of the shares of Delphi
Common Stock received by such Non-Management Shareholder as part of such Stock
Consideration Payment, except for (i) transfers by a Non-Management Shareholder
upon the death of such Non-Management Shareholder 

<PAGE>   57
                                      -51-


by will or pursuant to the laws of descent or distribution, (ii) transfers to a
Permissible Transferee, or (iii) transfers in compliance with the applicable
provisions of Rules 144 and 145 under the Securities Act, as amended from time
to time, in an amount not to exceed twenty-five percent (25%) of the number of
shares of Delphi Common Stock issued to such Shareholder as part of each Stock
Consideration Payment.

                  (d) In addition to the foregoing restrictions, during each
Three-Year Lock-up Period or Two-Year Lock-up Period, as applicable, each
Shareholder shall not make or engage in any "short sales" or any option or other
form of derivative transaction involving or relating to Delphi Common Stock
except that each Non-Management Shareholder may enter into a zero-premium collar
transaction as described in Exhibit D hereto (a "Collar"), provided, however,
that any such Collar must be provided by a nationally recognized financial
institution reasonably acceptable to Delphi and provided, further, that such
provider shall agree, in writing for the benefit of Delphi, not to hedge its
exposure to Delphi Common Stock under such Collar by means of any transaction
involving or relating to Delphi Common Stock (including but not limited to short
sales, options and any other form of derivative transaction relating to Delphi
Common Stock).

                  (e) Any transfers by the Shareholders following the expiration
of the applicable Three-Year Lock-up Period or Two-Year Lock-up Period, as the
case may be, of shares of Delphi Common Stock received by such Shareholder as a
Stock Consideration Payment shall be made only pursuant to an effective
registration statement or a valid exemption from the registration requirements
of the Securities Act; provided that with respect to any transfer pursuant to
such an exemption, Delphi may, in its discretion, require the transferor thereof
to provide to Delphi a written opinion of counsel reasonably acceptable to
Delphi, the form and substance of which opinion shall be reasonably satisfactory
to Delphi, to the effect that such transfer does not require registration under
the Securities Act.

                  (f) Notwithstanding anything to the contrary in this Section
6.10, in no event shall the transfer restrictions on 

<PAGE>   58
                                      -52-


any Stock Consideration paid in the publicly-traded common equity of another
entity pursuant to clause (ii) of Section 1.2(d) hereof as a result of a Change
of Control ("Change of Control Stock Consideration") be more restrictive than
the transfer restrictions applicable to the publicly-traded common equity of
such entity received by senior management of Delphi in connection with such
Change of Control, and in such circumstances, to the extent this Section 6.10
would be more restrictive with respect thereto, such lesser restrictions
applicable to senior management of Delphi shall be deemed incorporated by
reference herein and made applicable to the Change of Control Stock
Consideration.

                  (g) Notwithstanding anything to the contrary contained in this
Section 6.10, no transfer permitted pursuant to Section 6.10(b)(ii) or
6.10(c)(ii) shall be permitted unless and until the transferee of such shares
executes a written instrument in favor of Delphi agreeing to be bound by the
terms and provisions of this Agreement.

                  6.11 Change of Control. In the event of a Change of Control in
which the surviving entity or one of its subsidiaries or divisions manages
worker's compensation and accident and health reinsurance pools, then Delphi or
such surviving entity shall cause a majority of the members of Unicover's Board
of Directors to be selected from Unicover's senior management as constituted
immediately prior to such Change of Control, effective upon such Change of
Control and continuing until the end of the period to which the payment provided
for in Section 1.2(b)(v) hereof relates.

                  6.12 Employment of Chief Executive Officer. Delphi covenants
and agrees that in the event that during the Employment Period (as defined in
the Employment Agreement with John E. Pallat), John E. Pallat shall cease to act
as Chief Executive Officer of the Companies by reason of death or disability,
then any successor shall be reasonably acceptable to the Shareholders other than
John E. Pallat.

                  6.13 Effect on Business. Delphi covenants and agrees that it
will not take any action which materially inhibits 

<PAGE>   59
                                      -53-


or would otherwise have a material adverse effect on the business, operations or
financial condition of the Companies as the business is currently being
conducted or as contemplated in the financial projections referenced in Section
3.29 hereof, provided, that Delphi makes no representation as to the ability of
the Companies to achieve the results reflected in such projections.

                  6.14 401(k) Rollover. Effective as of the Closing Date,
employees of the Companies ("Company Employees") who are participants in the TRM
International, Inc. Savings and Profit Sharing Plan (the "TRM 401(k) Plan")
shall cease to be eligible for any future contributions to the TRM 401(k) Plan,
shall have a fully vested and nonforfeitable interest in their account balances
thereunder, and shall be entitled to a distribution of their account balances
under the TRM 401(k) Plan in accordance with and to the extent permitted by Code
Section 401(k)(10) and other applicable provisions of the Code. Company
Employees who receive an eligible rollover distribution (within the meaning of
Section 402(f)(2) of the Code, including a direct rollover distribution with the
meaning of Section 401(a)(31) of the Code) from the TRM 401(k) Plan shall,
subject to the provisions of Section 402 of the Code, be eligible to make a
rollover contribution to the Reliance Standard Life Insurance Company Retirement
Savings (401(k)) Plan or to another defined contribution plan of Delphi or its
affiliates (the "Buyer's 401(k) Plan"). To the extent that a direct rollover
distribution, within the meaning of Section 401(a)(31) of the Code, is made,
such rollover contribution may include promissory notes for loans made to
Company Employees under the terms of the TRM 401(k) Plan, provided such
rollovers are permitted by applicable provisions of the plans. Service by
Company Employees under the TRM 401(k) Plan shall be recognized under the
Buyer's 401(k) Plan for purposes of the eligibility to participate and vesting.

                  6.15  Nondisclosure of Confidential Information.

                  (a) Shareholders. Each Shareholder recognizes and acknowledges
that he has had in the past, currently has, and in the future may possibly have,
access to information concerning 

<PAGE>   60
                                      -54-


the business and affairs of Delphi and its subsidiaries or the Companies
("Confidential Information"). Each Shareholder agrees that he will not disclose
any such Confidential Information to any person, firm, corporation, association
or other entity for any purpose or reason whatsoever, except to authorized
representatives of Delphi, its subsidiaries and the Companies, or any of their
successors or affiliates, unless (i) the Shareholders can show that such
Confidential Information has become known or available to the public generally
through no fault of the Shareholders, (ii) disclosure is required by law or the
order of any governmental authority, (iii) the disclosing party reasonably
believes, based on the advice of counsel, that such disclosure is required in
connection with the defense of a lawsuit against the disclosing party, or (iv)
in each case of the Management Shareholder, disclosure by such Management
Shareholder of certain information is necessary or appropriate for the conduct
of the business of the Company, in accordance with Unicover's internal policies
in effect at the time of such disclosure, provided that, prior to disclosing any
information pursuant to clause (i), (ii) or (iii) above, the Shareholder shall
give prior written notice thereof to Delphi and provide Delphi with the
opportunity to contest such disclosure and shall cooperate with efforts to
prevent such disclosure. In the event of a breach or threatened breach by the
Shareholders of the provisions of this Section 6.12, Delphi and the Companies
shall be entitled to an injunction restraining the Shareholders from disclosing,
in whole or in part, such confidential information. Nothing herein shall be
construed as prohibiting Delphi and the Companies from pursuing any other
available remedy for such breach or threatened breach, including the recovery of
damages.

                  (b) Damages. Because of the difficulty of measuring economic
losses as a result of the breach of the foregoing covenants, and because of the
immediate and irreparable damage that would be caused for which they would have
no other adequate remedy, Delphi, each of the Companies and the Shareholders
agree that, in the event of a breach by any of them of the foregoing covenant,
the covenant may be enforced against them by, without limitation, injunctions
and restraining orders.

                                  ARTICLE VIII

                                   TERMINATION

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

                  (a)  by mutual written consent of each of the Companies and 
         Delphi;

                  (b) by either the Companies and the Shareholders as a group,
         on the one hand, or Delphi, on the other hand, if the purchase and sale
         of Ownership Interests as contemplated by this Agreement shall not have
         been consummated by the later to occur of (i) November 15, 1998 or (ii)
         one week after the expiration or termination of the waiting period
         required pursuant to the HSR Act; provided, however, that the right to
         terminate this Agreement pursuant to this Section 8.1(b) shall not be
         available to any party (with the Companies and the Shareholders deemed
         to be a single party for this purpose) whose failure to perform any of
         its obligations under this Agreement results in the failure of such
         transactions to be consummated by such time;

                  (c) by Delphi, if either of the Companies or any Shareholder
         shall have breached or failed to perform in any material respect any of
         its representations, warranties, 

<PAGE>   64
                                      -58-


         covenants or other agreements contained in this Agreement (which breach
         is not cured within 15 business days after receipt by either of the
         Companies or such Shareholders, as the case may be, of a written notice
         of such breach from Delphi specifying the breach and requesting that it
         be cured); or

                  (d) by either of the Companies and the Shareholders as a
         group, if Delphi shall have breached or failed to perform in any
         material respect any of its representations, warranties, covenants or
         other agreements contained in this Agreement (which breach is not cured
         within 15 business days after receipt by Delphi of a written notice of
         such breach from either of the Companies and the Shareholders
         specifying the breach and requesting that it be cured).

                  8.2 Effect of Termination. The termination of this Agreement
shall become effective upon delivery to the other party of written notice
thereof. In the event of the termination of this Agreement pursuant to the
foregoing provisions of this Article VIII, this Agreement shall become void and
have no effect, with no liability on the part of any party or its shareholders
or stockholders or directors or officers in respect thereof except for (i)
agreements which survive the termination of this Agreement, (ii) any liability
that Delphi, either of the Companies or any Shareholder might have arising from
a breach of this Agreement and (iii) in the event of termination pursuant to
Section 8.1(c) or (d), then notwithstanding Section 6.8, the breaching party
(with the Companies and the Shareholders deemed to be a single party for this
purpose) shall be liable to the other party for any expenses incurred in
connection with this Agreement and the transactions contemplated hereby, as well
as any damages in accordance with applicable law.

                                   ARTICLE IX

                                 INDEMNIFICATION

                  9.1  Delphi's Losses.

                  (a) Subject to the other provisions of this Article IX, each
Shareholder agrees, severally and not jointly, to indemnify and hold harmless
Delphi and each of the Companies and their respective officers, directors,
employees, stockholders, assigns, successors and affiliates (collectively, the
"Delphi Indemnified Parties", and each, a "Delphi Indemnified Party") from,
against and in respect of any and all Delphi's Losses (as defined below)
suffered, sustained, incurred or required to be paid by any Delphi Indemnified
Party by reason of (i) any representation or warranty made (whether as of the
date of this Agreement, as of the Closing Date or as of another date) by such
Shareholder in Article II of this Agreement or in Section 4 of either of the
Option Agreements, in the Disclosure Schedule or in any certificate or other
document or instrument delivered by or on behalf of any Shareholder in
connection herewith (all of which, for purposes of this Article IX, shall be
read as if they contained no qualifications for material adverse effect or
material adverse change and no other qualifications, exceptions or provisos
relating to materiality) being untrue or incorrect in any material (as defined
below) respect; or (ii) any failure by any of such Shareholder to observe or
perform any of their respective covenants and agreements set forth in this
Agreement in any material respect.

                  (b) Subject to the other provisions of this Article IX, the
Shareholders agree, severally and not jointly, to indemnify and hold harmless
the Delphi Indemnified Parties from, against and in respect of any and all
Delphi's Losses suffered, sustained, incurred or required to be paid by Delphi
by reason of (i) any representation or warranty made (whether as of the date of
this Agreement, as of the Closing Date or as of another date) by the Companies
and the Shareholders in Article III of this Agreement, in the Disclosure
Schedule or in any certificate or other document or instrument delivered by or
on behalf of the Companies in connection herewith (all of which, 

<PAGE>   66
                                      -60-


for purposes of this Article IX, shall be read as if they contained no
qualifications for material adverse effect or material adverse change and no
other qualifications, exceptions or provisos relating to materiality) being
untrue or incorrect in any material (as defined below) respect; (ii) any failure
by either of the Companies or the Shareholders to observe or perform any of its
covenants and agreements set forth in this Agreement in any material respect; or
(iii) the business, operations or assets of each of the Companies and
predecessors prior to the Closing Date or the actions or omissions of the
directors, officers, shareholders, employees or agents thereof prior to the
Closing Date, other than Delphi's Losses directly arising from matters expressly
disclosed in this Agreement or the Disclosure Schedule hereto.

                  (c) "Delphi's Losses" shall mean all damages (including,
without limitation, amounts paid in settlement with the Shareholders' consent,
not to be unreasonably withheld), losses, liabilities, claims, costs and
expenses (including, without limitation, reasonable fees of attorneys,
consultants and technical representatives). For purposes of indemnification
pursuant to this Section 9.1 and for purposes of the representations and
warranties and covenants herein insofar as they form a basis for such
indemnification, "material" shall mean that the amount of Delphi's Losses
suffered, sustained, incurred or required to be paid by reason of a
representation or warranty being untrue or incorrect or a failure to observe or
perform shall, taken together with all other Delphi's Losses suffered,
sustained, incurred or required to be paid by reason of any other such breach or
failure, have exceeded $1,000,000, in which event the Shareholders'
indemnification shall be effective with respect to all such Delphi's Losses in
excess of such amount. The aggregate amount of any Shareholder's liability under
this Article IX shall not exceed such Shareholder's Percentage of the
Consideration, provided, however, that if any liability arises on the part of
any Shareholder under this Article IX which is not satisfied in full, Delphi
shall be entitled to offset against any and all payments of Additional
Consideration which are then or thereafter become due to such Shareholder the
amount of such Shareholder's unpaid liability 

<PAGE>   67
                                      -61-


under this Article IX as of the date such Additional Consideration payment is
determined and Delphi's obligation to make such payment of Additional
Consideration shall be fully satisfied to the extent of such offset amount.

                  9.2  Shareholders' Losses.

                  (a) Subject to the other provisions of this Article IX, Delphi
agrees to indemnify and hold harmless the Shareholders from, against, for and in
respect of any and all Shareholders' Losses (as defined below) suffered,
sustained, incurred or required to be paid by the Shareholders by reason of (i)
any representation or warranty made (whether as of the date of this Agreement,
as of the Closing Date or as of another date) by Delphi in Article IV of this
Agreement, in the Disclosure Schedule or in any certificate or other document or
instrument delivered by or on behalf of Delphi in connection herewith being
untrue or incorrect in any material respect; or (ii) any failure by Delphi to
observe or perform its covenants and agreements set forth in this Agreement in
any material respect.

                  (b) "Shareholders' Losses" shall mean all damages (including,
without limitation, amounts paid in settlement with Delphi's consent, not to be
unreasonably withheld), losses, liabilities, claims, costs and expenses
(including, without limitation, reasonable fees of attorneys, consultants and
technical representatives).

                  9.3 Notice of Loss. Except to the extent set forth in the next
sentence, Delphi and the Shareholders will not have any liability under the
indemnity provisions of this Article IX with respect to a particular matter
unless a notice setting forth in reasonable detail the breach or other matter
which is asserted has been given to the Indemnifying Party (as defined below)
and, in addition, if such matter arises out of a suit, action, investigation,
proceeding or claim, such notice is given promptly, but in any event within
thirty (30) days after the Indemnified Party (as defined below) is given written
notice of the claim or the commencement of the suit, action, investigation or
proceeding. Notwithstanding the preceding sentence, 

<PAGE>   68
                                      -62-


failure of the Indemnified Party to give notice hereunder shall not release the
Indemnifying Party from its obligations under this Article IX, except to the
extent the Indemnifying Party is actually prejudiced by such failure to give
notice. With respect to Delphi's Losses pertaining to matters set forth in
Section 9.1, the Shareholders shall be the Indemnifying Party and the Delphi
Indemnified Party or Parties suffering such Delphi's Losses shall be the
Indemnified Party. With respect to the Shareholders' Losses, Delphi shall be the
Indemnifying Party and the Shareholder suffering such Shareholders' Losses shall
be the Indemnified Party.

                  9.4 Right to Defend. Upon receipt of notice of any suit,
action, investigation, proceeding or claim for which indemnification might be
claimed by an Indemnified Party, the Indemnifying Party shall be entitled to
assume control of the defense of any such suit, action, investigation,
proceeding or claim at its own cost and expense, and to settle or compromise
such suit, action, investigation, proceeding or claim in its discretion, subject
to the consent of the Indemnified Party, which consent will not be unreasonably
withheld or delayed. The Indemnified Party shall have the right, but not the
obligation, to participate at its own expense in defense thereof by counsel of
its own choosing, but the Indemnifying Party shall be entitled to control the
defense unless the Indemnified Party has relieved the Indemnifying Party from
liability with respect to the particular matter or the Indemnifying Party fails
to assume defense of the matter. In the event the Indemnifying Party shall fail
to defend, contest or otherwise protect in a timely manner against any such
suit, action, investigation, proceeding or claim, the Indemnified Party shall
have the right, but not the obligation, thereafter to defend, contest or
otherwise protect against the same and make any compromise or settlement thereof
and recover the entire cost thereof from the Indemnifying Party, including,
without limitation, reasonable fees of attorneys, consultants and technical
representatives, disbursements and all amounts paid as a result of such suit,
action, investigation, proceeding or claim or the compromise or settlement
thereof; provided, however, that the Indemnified Party must send a written
notice to the Indemnifying Party of 

<PAGE>   69
                                      -63-


any such proposed settlement or compromise, which settlement or compromise the
Indemnifying Party may reject, in its reasonable judgment, within thirty (30)
days of receipt of such notice. The Indemnified Party shall have the right to
effect a settlement or compromise over the objection of the Indemnifying Party;
provided, that if (i) the Indemnifying Party is contesting such claim in good
faith or (ii) the Indemnifying Party has assumed the defense from the
Indemnified Party, the Indemnified Party waives any right to indemnity therefor.
If the Indemnifying Party undertakes the defense of such matters, the
Indemnified Party shall not, so long as the Indemnifying Party does not abandon
the defense thereof, be entitled to recover from the Indemnifying Party any
legal or other expenses subsequently incurred by the Indemnified Party in
connection with the defense thereof.

                  9.5 Cooperation. The Delphi Indemnified Parties, the
Shareholders and each of their affiliates, successors and assigns shall
cooperate with each other in the defense of any suit, action, investigation,
proceeding or claim by a third party and, during normal business hours, shall
afford each other access to their books and records and employees relating to
such suit, action, investigation, proceeding or claim and shall furnish each
other all such further information that they have the right and power to furnish
as may reasonably be necessary to defend such suit, action, investigation,
proceeding or claim.

                  9.6 Subrogation. In the event the Indemnifying Party shall be
obligated to indemnify the Indemnified Party pursuant to this Article IX, the
Indemnifying Party shall, upon payment of such indemnity in full, be subrogated
to all rights of the Indemnified Party with respect to the claims to which such
indemnification relates; provided, however, that the Indemnifying Party shall
only be subrogated to the extent of any amounts paid by it pursuant to this
Article IX in connection therewith.

                                  MISCELLANEOUS

                  10.1 Survival of Covenants, Agreements, Representations and
Warranties.

                  (a) Covenants and Agreements. All covenants and agreements
made hereunder or pursuant hereto or in connection with the transactions
contemplated hereby shall survive the Closing Date and shall continue in full
force and effect thereafter according to their terms without limit as to
duration unless otherwise expressly provided therein.

                  (b) Representations and Warranties. All representations and
warranties contained herein shall survive the Closing Date and shall continue in
full force and effect thereafter for the period from the Closing Date until June
1, 2000, except that (i) the representations and warranties in Section 3.17
shall survive until ten (10) days after all potential claims thereon shall be
barred by the applicable statute of limitations and (ii) the representations and
warranties made in Article II shall survive indefinitely; provided that, in the
event any claim for a breach of any representation or warranty has been asserted
with reasonable specificity prior to the last day such representation or
warranty would otherwise survive pursuant to this Section 10.1, such
representation and warranty shall survive until final disposition of such claim.

                  10.2 Closing and Waiver.

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

<PAGE>   74
                                      -68-


                  10.5 Interpretation. The headings of articles and sections
herein are for convenience of reference, do not constitute a part of this
Agreement, and shall not be deemed to limit or affect any of the provisions
hereof. As used in this Agreement, "person" means any individual, corporation,
limited or general partnership, joint venture, association, joint stock company,
trust, unincorporated organization or government or any agency or political
subdivision thereof; "subsidiary" of any person means (i) a corporation more
than 50% of the outstanding voting stock of which is owned, directly or
indirectly, by such person or by one or more other subsidiaries of such person
or by such person and one or more subsidiaries thereof or (ii) any other person
(other than a corporation) in which such person, or one or more other
subsidiaries of such person or such person and one or more other subsidiaries
thereof, directly or indirectly, have at least a majority ownership and voting
power relating to the policies, management and affairs thereof; and "voting
stock" of any person means capital stock of such person which ordinarily has
voting power for the election of directors (or persons performing similar
functions) of such person, whether at all times or only so long as no senior
class of securities has such voting power by reason of any contingency.

                  10.6 Amendment. This Agreement may not be amended except by an
instrument in writing signed on behalf of Delphi, each of the Companies and
Shareholders representing in excess of seventy-five percent (75%) of the
Ownership Interests held by Shareholders affected by such proposed amendment.

                  10.7 Assignment. This Agreement may not be assigned, other
than by Delphi to an affiliate of Delphi, by any party hereto except with the
prior written consent of the non-assigning parties.

                  10.8 No Third Party Beneficiaries. Nothing in this Agreement
shall confer any rights upon any person or entity which is not a party or
permitted assignee of a party to this Agreement, except for rights of Delphi
Indemnified Parties as set forth in Article IX (Indemnification).

                                      -69-


                  10.9 Governing Law. This Agreement shall be governed by, and
construed in accordance with, the laws of the State of New York without regard
to principles of conflicts of laws.

                  10.10 Entire Agreement. This Agreement (including the Exhibits
and Schedules hereto), the Employment Agreements, the Letter Agreements, the
Side Letters, the Non-competition Agreements and the Option Agreements
constitute the entire agreement between the parties pertaining to the subject
matter hereof and thereof, and supersede all prior agreements or understandings
as to such subject matter. No party hereto has made any representation or
warranty or given any covenant to the other except as set forth in the
Transaction Documents including the Schedules hereto. Without limiting the
generality of the foregoing, the Shareholders make no representation to Delphi
with respect to (a) any projections, estimates or budgets delivered to Delphi of
future revenues, expenses or expenditures or future results of operations of the
Companies or (b) any other documents or information made available to Delphi or
its counsel, accountants or advisers except in the case of either (a) or (b) as
expressly covered by the representations and warranties contained in Articles II
and III hereof. Specifically, and in that regard, Delphi agrees that it has not
relied on any information or statements contained in that certain Confidential
Information Memorandum, dated July, 1998 (except to the extent that consistent
information or statements were made in the representations and warranties herein
or in the Option Agreements) and is relying solely on its own due diligence and
the representations and warranties contained herein and in the Option
Agreements.

                  10.11 Relationship Among Certain Agreements. In the event that
a final determination has been made, in accordance with the arbitration
provisions of Exhibit B hereto, that Delphi has breached the provisions of
Section 6.13 hereof, then the Non-Competition Agreements shall automatically
become void and have no effect. Any (i) termination of John E. Pallat other than
(A) for Cause (as defined in his Employment Agreement) or (B) as a result of a
breach by him of his Employment 

<PAGE>   76
                                      -70-


Agreement or (ii) breach by Delphi of Section 2 of his Employment Agreement will
also be deemed a breach by Delphi under this Agreement. The remedy contained in
this Section 10.11 shall be in addition to any other remedy available pursuant
to this Agreement.

                  10.12 No Recourse Against Others. No director, officer or
employee, as such, of Delphi, its Subsidiaries or either of the Companies shall
have any liability for any obligations of Delphi or either of the Companies,
respectively, under this Agreement for any claim based on, in respect of or by
reasons of such obligations or their creation.

                  10.13 Validity. The invalidity or unenforceability of any
provision of this Agreement shall not affect the validity or enforceability of
any other provisions of this Agreement, which shall remain in full force and
effect.

                  10.14 Severability. In case any provision of this Agreement
shall be invalid, illegal or unenforceable, it shall, to the extent possible, be
modified in such manner as to be valid, legal and enforceable but so as to most
nearly retain the intent of the parties. If such modification is not possible,
such provision shall be severed from this Agreement. In either case the
validity, legality and enforceability of the remaining provisions of this
Agreement shall not in any way be affected or impaired thereby.

                  10.15 Facsimiles. Any facsimile signature of any party hereto
or to any other agreement executed in connection herewith (other than on any
securities or transfer instruments) shall constitute a legal, valid and binding
execution hereof by such party.

                  10.16 Construction. The parties have participated jointly in
the negotiation and drafting of this Agreement. In the event that an ambiguity
or question of intent or interpretation arises, this Agreement shall be
construed as if drafted jointly by the parties and no presumption or burden of
proof shall arise favoring or disfavoring any party by virtue of the authorship
of any of the provisions of this Agreement.

                                                     to Stock Purchase Agreement


Consideration Determination Procedures


OBJECTIVE:

                  The following procedures are intended to be a measurement tool
for the Consideration to be paid pursuant to Section 1.2 of the Stock Purchase
Agreement (the "Agreement") (to which these procedures are attached as Exhibit
B) based upon the Pre-tax Cash Flow of the Companies. Capitalized terms used and
not defined herein shall have the meanings set forth in the Agreement.

                  Pre-tax Cash Flow for the periods following the Closing will
be adjusted dollar-for-dollar positively for any expense, capital expenditure,
allocation or any other items that reduce Pre-tax Cash Flow which were
determined or imposed by Delphi or its affiliates that were not contemplated in
the stand-alone projections referenced in Section 3.29 of the Agreement. Pre-tax
Cash Flow for the periods following the Closing will be adjusted
dollar-for-dollar negatively for any investment or other items that increase
Pre-tax Cash Flow that do not represent cash flow generated by the Companies.

CALCULATION:

                  Delphi will provide the Shareholders with a detailed written
calculation of its determination of Pre-tax Cash Flow (each such determination,
a "Delphi Determination") within three months after the end of the relevant
measurement period. Pre-tax Cash Flow will be the result of subtracting actual
cash expenditures of the Companies from actual cash received by the Companies
for each relevant measurement period. Actual cash received by the Companies will
include actual cash receipts from services provided to the Unicover Occupational
Accident Facility, the Lincoln National Life Insurance Company Occupational
Accident Facility, the Reliance Insurance Company

                                      -2-

Facility, the Loss Portfolio Transfer Facility, the Buffer Facility, any new
facilities, investment income on cash received through the end of the quarter in
which such cash is received and any other actual cash received. Actual cash
expenditures will include actual costs related to salaries, taxes (other than
federal, state and local income taxes), benefits, bonuses (other than through
the Employee Limited Liability Company), rent, utilities, telecommunications,
travel and entertainment, professional fees, information systems, insurance,
miscellaneous and any other actual expenditures (including capital
expenditures). Actual cash expenditures will exclude any income taxes that
result from the activities of the Companies and any bonuses paid through the
Employee Limited Liability Company.

ARBITRATION:

                  If the Shareholders shall disagree with any Delphi
Determination, the Shareholders shall give written notice of such disagreement
to Delphi within 10 business days after receipt of the applicable Delphi
Determination. If, within 20 business days after Delphi's receipt of such notice
of disagreement, Delphi and the Shareholders are unable to agree with regard to
any Delphi Determination, the disagreement may be submitted to arbitration by
either Delphi or the Shareholders, which arbitration election shall be final and
binding on the parties. The party instituting the arbitration procedures shall
give written notice to the other party of its election to arbitrate, and such
notice shall specify the name and address of the person designated to act as an
arbitrator on its behalf. Within 10 business days after the service of such
notice, the second party shall notify the first party of the appointment of the
person designated to act as arbitrator on the second party's behalf. If the
second party fails to notify the first party of the appointment of its
arbitrator within the period specified above, then the second arbitrator shall
be appointed by the American Arbitration Association ("AAA"), or any
organization successor thereto, in accordance with its then prevailing rules.
The two arbitrators so chosen shall meet within 10 business days after the
second arbitrator is appointed and shall select the third arbitrator by mutual


<PAGE>   82
                                      -3-


agreement. If the two arbitrators shall fail to appoint a third arbitrator
within 10 business days after the second arbitrator is appointed, then the third
arbitrator shall be appointed by AAA, or any organization successor thereto, in
accordance with its then prevailing rules. Each arbitrator chosen or appointed
pursuant to this Exhibit B shall be an active or retired officer of an insurance
or reinsurance company, experienced and in good standing in the insurance or
reinsurance industry and shall be a disinterested person.

                  The arbitrators shall review the relevant provisions of the
Stock Purchase Agreement and any documents or materials supplied by either party
supporting such party's position. The arbitrators shall render their decision
with regard to the disputed Delphi Determination upon the concurrence of at
least two of their number not later than 30 business days after the appointment
of the third arbitrator. The decision of the arbitrators shall be in writing,
and counterpart copies shall be delivered to each of Delphi and the
Shareholders. In rendering their decision, the arbitrators shall have no power
to modify any of the provisions of the Stock Purchase Agreement. The decision of
the arbitrators shall be final and binding. All arbitration proceedings shall
occur in New York, New York and, absent express written agreement by the parties
to the contrary, shall be governed by the then prevailing rules of AAA, or any
organization successor thereto. Judgment may be entered on the award of the
arbitrators and may be enforced in accordance with the laws of the State of New
York.

                  Immediately upon a party hereto giving written notice of its
election to arbitrate hereunder, Delphi agrees upon reasonable advance request
to cause the Companies to provide the Shareholders with access to the books and
records of the Companies which reasonably relate to the Delphi Determination in
dispute at reasonable times during the normal business hours of the Companies.

                  Each party shall pay the fees and expenses of the original
arbitrator that it appointed (or, in the case of the second party, the
arbitrator appointed on its behalf if it should fail to appoint its own
arbitrator). The fees and expenses 

<PAGE>   83
                                      -4-


of the third arbitrator and all other expenses of the arbitrators shall be borne
by the parties equally. Each party shall bear the expense of its own counsel and
the preparation and presentation of proof, or supportive documentation.

                           RE: UNICOVER MANAGERS, INC.

Dear Mr. [Name]:

                  Reference is made to the Stock Purchase Agreement dated as of
the date hereof by and among Delphi Financial Group, Inc. ("Delphi"), Unicover
Managers, Inc. and Unicover Intermediaries, LLC (collectively, the "Companies")
and the Shareholders named therein (the "Stock Purchase Agreement") and the
Option Agreements dated as of the date hereof by and among Delphi and the
Shareholders (the "Option Agreements"). Terms used but not defined in this
letter agreement have the meanings assigned thereto in the Stock Purchase
Agreement or the Option Agreements.

                  Simultaneously with the execution hereof, Delphi, the
Companies and the Shareholders have entered into the Stock Purchase Agreement
and the Option Agreements. Subject to the conditions set forth in the Stock
Purchase Agreement and the Option Agreements, the Ownership Interests in the
Companies held by the Shareholders will be purchased by Delphi for, in part, the
Additional Consideration and Exercise Consideration set forth in the Stock
Purchase Agreement and the Option Agreements, respectively.

                  Due to circumstances personal to you, without affecting in any
way (a) your obligations under the Stock Purchase

Delphi's obligations to, the other Shareholders under the Stock Purchase

until the Closing Date) in cash in lieu of 98.325% of the Additional
Consideration payments and 100% of the Exercise Consideration payments that may
become due to you pursuant to the Stock Purchase Agreement and Option
Agreements, respectively, provided, however, that you will repay, pursuant to
Section 1.2 of the Stock Purchase Agreement and Section 3 of the Option
Agreements, your Shareholder's Percentage of any Excess Distributions. Delphi
hereby agrees to waive your representation and warranty under Section 2.3(b) of
the Stock Purchase Agreement insofar as such section conflicts with the
provisions of this letter agreement. By your execution of this letter agreement,
you acknowledge that your receipt of this amount satisfies in all respects the
obligations of Delphi pursuant to the Stock Purchase Agreement and the Option
Agreements to make any Additional Consideration payments or payments of Exercise
Consideration to you and, together with the payment to which you may be entitled
pursuant to Section 1.2(a) of the Stock Purchase Agreement and Section 3(a)(i)
of the Option Agreements, constitutes payment in full for your Ownership
Interests in the Companies and, to the extent the Options granted in the Option
Agreements are exercised, Olga and ARRCL. Furthermore, you hereby waive any and
all rights you may have to receive payment of any Consideration or Exercise
Consideration (including, without limitation, any and all Additional
Consideration), other than the payments to which you may be entitled pursuant to
Section 1.2(a) of the Stock Purchase Agreement and Section 3(a)(i) of the Option
Agreements. Finally, you reiterate the representations and warranties contained
in Section 2.2 of the Stock Purchase Agreement and Section 4 of the Option
Agreements in relation to this letter agreement as fully as if this letter
agreement were referenced therein, and agree that the provisions of Sections
6.3, 7.2(a) and 9.1 of the Stock Purchase Agreement shall for all purposes be
applied as if this letter agreement were so referenced.

Dear Sirs:

                  Reference is made to the Stock Purchase Agreement dated as of
the date hereof by and among Delphi Financial Group, Inc. ("Delphi"), Unicover
Managers, Inc. and Unicover Intermediaries, LLC (collectively, the "Companies")
and the Shareholders named therein (the "Stock Purchase Agreement"). Terms used
but not defined in this letter agreement have the meanings assigned thereto in
the Stock Purchase Agreement.

                  Simultaneously with the execution hereof, Delphi, the
Companies and the Shareholders have entered into the Stock Purchase Agreement.
Subject to the conditions set forth in the Stock Purchase Agreement, the
Ownership Interests in the Companies held by the Shareholders will be purchased
by Delphi for, in part, the Additional Consideration set forth in the Stock
Purchase Agreement.

                  Without otherwise affecting (a) your rights and obligations
under the Stock Purchase Agreement or (b) the rights and obligations of, or
Delphi's obligations to, the Non-Management Shareholders under the Stock
Purchase Agreement, as 

<PAGE>   94

an additional inducement to Delphi's willingness to enter into the Stock
Purchase Agreement, you hereby grant to Delphi the option to sell to you Delphi
Common Stock equal in value to 10% of each Additional Consideration payment owed
to you pursuant to Section 1.2(b) of the Stock Purchase Agreement (based on the
Market Price of such Delphi Common Stock as of the end of the period for which
such Additional Consideration payment is being made), which option shall be
exerciseable by Delphi at any time up to the time of such Additional
Consideration payment. The Management Shareholders shall pay as the exercise
price 10% of each Additional Consideration payment, which payment may be made by
Delphi withholding an amount of cash equal to such exercise price from the
Additional Consideration payment that would otherwise have been paid to you in
cash and applying such amount in full payment of the exercise price. Any such
shares of Delphi Common Stock shall be treated for all purposes under the Stock
Purchase Agreement as Stock Consideration.

                  This letter agreement shall become effective only upon
consummation of the Stock Purchase Agreement. This letter agreement may not be
amended or any provision hereof waived or modified except by an instrument in
writing signed by each of the parties hereto. This letter agreement shall be
