ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.
- --------------------------------------------- 

       On June 25, 1997, SSDC Corp., a wholly-owned subsidiary of CORE, INC., a
Massachusetts corporation ("CORE"), acquired the assets of Social Security
Disability Consultants Limited Partnership ("SSDC") and Disability Services,
Inc. ("DSI"), based in Novi, Michigan, pursuant to an Asset Purchase Agreement
dated June 14, 1997 (the "Purchase Agreement").  Pursuant to the Purchase
Agreement, all of the assets of SSDC/DSI were acquired in exchange for the
payment of an initial purchase price of $5 million, additional purchase price of
$1.5 million, payable quarterly through June 24, 1998, and up to an additional
$.920 million in future, performance-related payments. The purchase price, which
CORE paid from its liquid assets, is subject to certain adjustments as set forth
in the Purchase Agreement. The purchase price was the result of arms' length
negotiations between CORE and SSDC/DSI.

       Prior to the consummation of this transaction, there was no material
relationship between SSDC, DSI or their stockholders and officers, R. Gary
Dolenga and Phylis M. Dolenga, and CORE or any of CORE's affiliates, directors
or officers, or any associate of any such director or officer.

       With the SSDC/DSI assets, SSDC Corp. will continue to specialize in
social security disability benefits advocacy and Medicare coordination of
benefits for large Fortune 500 employers and others.

       In connection with CORE's acquisition of SSDC/DSI, CORE also entered 
into an Employment Agreement dated June 25, 1997 and an Option Agreement dated 
June 14, 1997 with R. Gary Dolenga.

be due by said returns or on any assessments received by any Seller or have made

     The provisions for taxes (federal, state, local and other), and interest
and penalties, if any, with respect thereto, reflected in the Balance Sheets of
Sellers are adequate to cover any and all taxes and any interest and penalties
in connection therewith which have been or may be assessed with respect to the

ended on the date of said Balance Sheet and all prior periods.  No claim or
liability is pending or has been assessed or threatened against any Seller in
connection with any such taxes except as reflected in the Balance Sheet.  The
federal income tax returns of Sellers have been audited by the IRS for the year
ended October 31, 1990, and no additional taxes are due.

     Sellers are not, and on the Closing Date will not be, a consenting
corporation within the meaning of Section 341(f) of the Internal Revenue Code.

     All taxes or other assessments and levies which Sellers are or were
required by law to withhold or collect have been duly withheld and collected,

suits, or proceedings pending or threatened against or affecting any Seller or
Founder or the Subject Assets or the property of Sellers in any court or before
any federal, state, municipal or other governmental department, commission,
board or other instrumentality or before any arbitrators (all of which claims
are adequately covered by insurance, or are adequately reserved for in Sellers'
financial statements).

     Sellers have complied in all material respects with all applicable laws
including, without limitation, environmental laws (including rules, regulations,
codes, plans, injunctions, judgments, orders, decrees, rulings, and charges
thereunder) of federal, state, local, and foreign governments (and all agencies
thereof) and there are no pending or, to the best knowledge of each Seller and
Founder, threatened governmental investigations involving any Seller or Founder,

decrees or stipulations to which any Seller or Founder is a party affecting any
Seller or Founder or any of their respective services or products, and Sellers
and Founder are not in default with respect to any judgment,

regulations or procedures relating to Sellers' Business which would materially
and adversely effect the continued prosecution of the open cases.  Accordingly,
to best of Sellers' and Founder's knowledge, future fees from the open cases

development causing a breach or impending breach of any of the representations

<PAGE>
 
SECTION 5.12 MONTHLY FINANCIAL STATEMENTS; AUDITED FINANCIAL STATEMENTS

     (a)  Monthly Financial Statements.  Upon Purchaser's request, Sellers shall
          ----------------------------                                          
deliver to CORE a balance sheet and related statements of income and retained
earnings and cash flows for the interim period ending at the end of the prior
month, which financial statements shall not reflect any material adverse change
in the financial condition or liabilities of Sellers.  Such financial
statements, when delivered to CORE, shall be in accordance with the books and
records of Sellers, will be complete and correct in all material respects and
fairly present the financial position of Sellers as of dates therein indicated
and the results of the operations of Sellers for the periods so ended (subject
to normal year end adjustments in the case of any interim financial statements
for which full year financial statements have been delivered), all in conformity
with GAAP.

     (b)  Audited Financial Statements.  On or before June 20, 1997, Sellers
          ----------------------------                                      
shall deliver to CORE financial statements of Sellers audited by Correll-Porvin
Associates for the three years ended December 31, 1996 and audited statements of
operations and cash flows for the same years and any other period deemed
necessary or appropriate by CORE in connection with CORE's disclosure
obligations under the federal securities laws (the "Audited Financial
Statements").  Such Audited Financial Statements shall be substantially similar
to the unaudited financial statements of Sellers set forth in Exhibit 2.4 hereof
                                                              -----------       
for the same periods and include Seller's independent auditors' opinion in a
form satisfactory to CORE.  Without limiting the generality of the foregoing,
the Audited Financial Statements shall not be substantially similar to the
unaudited financial statements of Sellers if for any period revenues or net
income vary by more than 5%.

SECTION 5.13 BULK SALES LAW

     Sellers and Founder shall, jointly and severally, indemnify and hold
Purchaser and CORE harmless from any loss, cost or liability (including
reasonable attorney's fees) incurred by Purchaser or CORE as a result of non-
compliance with any applicable bulk sales law, fraudulent conveyance law or
similar law with respect to the transactions contemplated herein.

SECTION 5.14 NAME CHANGE

     At the request of Purchaser, including a request made after the Closing,
each Seller shall change its name to a name that does not contain any reference
to "SSDC" or "Social Security Disability Consultants" or any derivatives
thereof.

SECTION 5.15 DIAMOND ENTERTAINMENT ASSETS

     At Closing, Founder and Sellers shall cause Diamond Entertainment, Inc., a
Michigan corporation in which Founder is the sole stockholder ("DE"), to enter
into an agreement with

                                       30
<PAGE>
 
Purchaser, in a form acceptable to Purchaser and Sellers, which provides for
Purchaser's use of DE's suite at the Palace of Auburn Hills for appropriate
consideration.  Founder and each Seller, jointly and severally, represent and
warrant that DE's license for the suite in the Palace at Auburn Hills is the
sole asset of DE.

SECTION 5.16  NON-COMPETITION; NON-SOLICITATION

     Founder and each Seller hereby agrees that, from and after the Closing Date
through the "Covenant End Date" (as defined below) none of them shall (a) serve,
directly or indirectly, as an operator, owner, partner, consultant, officer,
director, or employee of any firm, entity or business or corporation engaged in
the business presently being conducted by a Seller (or any business related
thereto) within the United States; (b) solicit or attempt to solicit, or accept
business from, any entity which is a client or customer of CORE, Purchaser, any
Seller (including CORE's subsidiaries) or which at any time during the twelve
month period prior to the Closing Date, was a client or customer of any of the
Business, for the purpose of doing business with such client or customer in
competition with Purchaser or CORE (including CORE's subsidiaries) (for the
purpose of this covenant, the clients and customers of Purchaser shall include
those entities with which Sellers had held discussions or negotiations
concerning the Business within the twelve month period prior to the Closing
Date), or (c) solicit, attempt to hire, or hire any employee or consultant of
Purchaser (including Continuing Employees) or CORE (including CORE's
subsidiaries), or assist in such solicitation or hiring by any other person or
entity, or encourage any employee or consultant or Purchaser (including
Continuing Employees) or CORE (including CORE's subsidiaries) to terminate his
or her relationship with Purchaser or CORE.

     For purposes of this Agreement, "Covenant End Date" shall mean the date
ending one year after R. Gary Dolenga's termination of employment with Purchaser
(or any of Purchaser's affiliated corporations) for any reason but not later
than July 1, 2000.

     It is agreed that the remedy at law for any breach of the foregoing shall
be inadequate and that CORE and Purchaser shall be entitled to any other remedy
permitted by law.  In the event that this Section shall be determined by
arbitrators or by any court of competent jurisdiction to be unenforceable by
reason of its extending for too great a period of time or over too large a
geographic area or over too great a range of activities, it shall be interpreted
to extend only over the maximum period of time, geographic area or range of
activities as to which it may be enforceable.  Nothing herein contained shall
prevent Founder or any Seller from holding or making an investment in securities
listed on a national securities exchange or sold in the over-the-counter market,
provided such investments do not exceed in the aggregate five percent (5%) of
the issued and outstanding capital stock of a corporation which is a competitor
within the meaning of this Section.

                  ADDITIONAL AGREEMENTS OF CORE AND PURCHASER

SECTION 6.1  EMPLOYMENT ARRANGEMENTS AND EMPLOYEE BENEFITS
- ----------------------------------------------------------

     (a)  Purchaser intends to offer employment, commencing as of the
Closing Date, at substantially the same wages, salary, benefits, hours and
conditions in effect immediately prior to the Closing, to all employees listed
on Schedule 2.12 with such changes in the ordinary course of business of which
   -------------                                                              
any Seller notifies Purchaser (other than those employees listed on Schedule 6.1
                                                                    ------------
including Purchaser's revisions to Schedule 6.1 at or prior to Closing);
                                   ------------                         
provided, however, Purchaser reserves the right to make changes to such wages,
salary, benefits, hours and conditions.  Those employees who shall accept said
offer of employment with Purchaser and who shall actually commence active
employment with Purchaser shall collectively be referred to as the "Continuing
Employees."

     Notwithstanding the foregoing, and without breaching the foregoing,
Purchaser reserves the right to review staffing levels, wages, benefits and
conditions of employment after the Closing, and to make appropriate changes, if
in its judgment such changes are necessary in light of then existing business
conditions.

     (b)  Unless expressly listed as an Assumed Liability, Sellers shall retain
responsibility for any hospital, medical, dental, life insurance, disability,
workers' compensation and other employee welfare benefit plan premiums due and
payable for coverage prior to the Closing Date. Hospital, medical, dental, life
insurance, disability, workers' compensation and other employee welfare benefit
plans listed on Schedule 2.13 for which premiums will be accrued and payable for
                -------------   
coverage of the Continuing Employees on or after the Closing Date shall be the
responsibility of Purchaser. Unless expressly listed as an Assumed Liability on
Schedule 1.2, Sellers shall remain responsible for paying all unpaid vacation,
sick-leave or other time-off pay accrued by all employees through the Closing
Date.

     (c)  Unless expressly listed as an Assumed Liability on Schedule 1.2,
Sellers shall pay to all Continuing Employees all benefits accrued to such
employees prior to the Closing Date (including, without limitation, vacation pay
and time-off pay) as soon as practicable after Closing, but in no event more
than 14 days after Closing.

                                       32
<PAGE>
 
     (d)  At closing CORE shall grant Incentive Stock Options for 140,000
shares of CORE Common Stock to Continuing Employees (the "SSDC Employee ISOs").
Allocation of the options among Continuing Employees shall be as mutually agreed
between CORE, Founder and Sellers.  The documentation evidencing the SSDC
Employee ISOs shall be in the form substantially similar to the form used for
CORE employees, except the Incentive Stock Option Agreement will provide for
full accelerated vesting upon death, disability or retirement of the employee.

     At the end of each calendar quarter of each year, provided Founder is
an employee of Purchaser, CORE shall grant to Founder incentive stock options
for the purchase of CORE Common Stock (with an exercise price equal to the
stock's then current fair market value, a five year vesting schedule, including
20% vesting at grant and a 5 year term) in an amount equal to the number of SSDC
Employee ISOs terminated, without exercise, during the prior calendar quarter.

     (e)  No provision of this Section 6.1 shall create any third-party-
beneficiary rights in any employee or former employee (including any beneficiary
thereof) of any Seller or Purchaser.

SECTION 6.2  ACCOUNTS RECEIVABLE; CASH AND A/R ACCOUNT

     For the purposes of this Agreement "Cash and A/R Account" shall consist of
cash, cash equivalents and accounts receivable (net of reserves) of Sellers
transferred to Purchaser at Closing. Founder and Sellers agree that the amount
of the Cash and A/R Account transferred to Purchaser at Closing shall be equal
to the amount of Assumed Liabilities as such liabilities would be set forth on a
properly prepared balance sheet. Cash and accounts receivable of Sellers in
excess of the Cash and A/R Account required to satisfy the preceding sentence
shall be retained by Sellers.

SECTION 6.3  NO BREACHES OF REPRESENTATIONS AND WARRANTIES

     Between the date hereof and Closing, CORE will not take any action which
would cause or constitute a breach, or would, if it had been taken immediately
prior to the date hereof, have caused or constituted a breach, of any of the
representations and warranties of CORE set forth herein. CORE will, in the event
of, and promptly after the occurrence of or the impending or threatened
occurrence of, any event which would cause or constitute a breach or would, if
it had occurred immediately prior to the date hereof, have caused or constituted
a breach of any of the representations and warranties of CORE set forth herein,
give detailed notice to Sellers; and CORE will use its reasonable best efforts
to prevent or promptly to remedy such breach.

SECTION 6.4  BEST EFFORTS

     CORE will use its reasonable best efforts to effectuate the transactions
hereby

                                       33
<PAGE>
 
contemplated, to perform all the covenants and agreements contained herein, and
to fulfill the conditions of CORE's obligations under this Agreement.

                                  ARTICLE VII

                     INDEMNITY BY THE SELLERS AND FOUNDER

SECTION 7.1  INDEMNIFICATION

     Each Seller and Founder, jointly and severally, hereby agree to indemnify,
defend, save and hold CORE and Purchaser harmless from and against, and will
reimburse CORE and its subsidiaries or Purchaser, and any person serving as
officers, directors, agents, counsel or employees thereof, as the case may be,
for all losses, liabilities, costs, damages, assessments, taxes, judgments,
deficiencies, and expenses of any nature whatsoever (including reasonable
attorneys' fees and other costs and expenses incident to any suit, action or
proceeding) incurred by CORE or Purchaser which shall arise out of or result
from or constitute any breach of any representation, warranty, covenant, or
agreement of any Seller or Founder in this Agreement, or in any certificate,
schedule or exhibit delivered pursuant hereto, and for any undisclosed
liabilities of any Seller or Founder incurred prior to the Closing Date. Each
Seller and Founder hereby releases every other Seller and Founder from any
obligation of contribution, indemnity or the like relating to any claims under
this Article.

     The amount of the indemnity to which CORE and Purchaser shall be entitled
hereunder shall be measured by the sum of (a) the amount of cash required to
restore the circumstances or condition which constitutes the breach of any such
representation, warranty, covenant or agreement or non-fulfillment of any such
obligation to what it would have been on the Closing Date had such breach or
non-fulfillment not occurred and (b) all reasonable attorneys' fees and other
costs and expenses incident to any suit, action or proceeding relating thereto.

SECTION 7.2  DETERMINATION OF LIABILITY

     In the event that at any time or from time to time, CORE shall determine
that it or Purchaser is entitled to indemnification under Section 7.1 hereof, it
shall give written notice to the Sellers and Founder specifying the cause, the
amount of such claim and the 20 day objection period described in the next
sentence. Sellers or Founder may object to the claim by delivering written
notice thereof to CORE within twenty (20) days after receipt of CORE's written
notice. Failure on the part of Sellers or Founder so to object shall constitute
an acceptance of the CORE's claim and if the amount to which CORE or Purchaser
is entitled is not paid by Sellers or Founder within ten (10) days of such
determination, then CORE shall have the right to satisfy all or part of such
indemnification obligations of Seller by offset against the Additional Purchase
Price. In the event such claim exceeds the amount of the Additional Purchase
Price, or the Additional Purchase Price has previously been paid, or the
Additional Purchase Price is

                                       34
<PAGE>
 
otherwise insufficient to fully satisfy such claim, Founder and Sellers shall be
jointly and severally liable to CORE and Purchase for payment of such claim.

     In the event that Sellers or Founder shall so object and CORE and Sellers
or Founder shall fail to reach an agreement as to the entitlement of CORE or
Purchaser to indemnification or the amount thereof within sixty (60) days after
the written notice by Sellers or Founder objecting to the claim, then so much of
the matter as may be in dispute shall be submitted to the American Arbitration
Association in Orange County, California for settlement in accordance with its
rules, and the decision as to the disputed matter rendered by the arbitrator or
arbitrators shall be binding on all parties to this Agreement. CORE, Purchaser,
Sellers and Founder shall act upon such award in like manner as though it
constituted an agreement reached between the parties. CORE or Purchaser, on one
hand, and Seller and Founder on the other hand, shall each bear the cost of
their respective expenses and shall each pay fifty percent (50%) of the
arbitrators' charges.

SECTION 7.3 DEFENSE OF CLAIMS

     After receipt by CORE or Purchaser of notice of the existence of any claim
made or threatened by a third party, to which the indemnification obligations
hereunder apply, CORE shall give written notice thereof to Founder and Sellers,
but the omission to so notify Founder and Sellers will not relieve Founder and
Sellers from any liability except to the extent that Founder and Sellers shall
have been materially prejudiced as a result of the failure in giving such
notice. Such notice shall state the information then available regarding the
amount and nature of such claim and shall specify the provision or provisions of
this Agreement under which the liability or obligation is asserted. If within
ten (10) days after receiving such notice, Founder or any Seller gives written
notice to CORE stating that he or it disputes and intends to defend against such
claim at Founder or Seller's own cost and expense (subject to the consent of
CORE which consent shall not be unreasonably withheld but which consent may be
conditional upon bonding or other evidence of ability to pay upon a judgment)
provided Seller's or Founder's counsel in such defense is acceptable to CORE,
then CORE shall make no payment on such claim as long as Seller is conducting a
good faith and diligent defense. Notwithstanding anything herein to the
contrary, CORE and Purchaser shall at all times have the right to fully
participate in such defense at CORE's and Purchaser's own expense directly or
through counsel; provided, however, if the named parties to the action include
both (i) any Seller or Founder and (ii) Purchaser or CORE and representation of
both parties by the same counsel would be inappropriate under applicable
standards of professional conduct, the expense of one separate counsel for CORE
or Purchaser shall be paid by Founder and Sellers. If no timely notice of intent
to dispute and defend is given by any Seller or Founder, or if such diligent
good faith defense is not being or ceases to be conducted, after written notice
to Founder and Sellers and the failure of any Seller to initiate or conduct such
a defense within ten (10) days after such notice, CORE, at the expense of
Founder and Sellers, shall undertake the defense of such claim, liability or
expense, and shall have the right to compromise or settle the same. If such
claim,

                                       35
<PAGE>
 
liability or expense is one that by its nature cannot be defended solely by a
Founder or Seller then CORE and Purchaser shall make available all information
and assistance that Founder or Sellers may reasonably request and shall
cooperate with the Founder or Sellers in such defense provided, Founder or
Sellers shall reimburse CORE and Purchaser for their costs and expenses in
providing such assistance.

SECTION 7.4 RECOURSE TO SELLERS AND FOUNDER

     Any amounts offset against the Additional Purchase Price shall in no way
limit CORE's or Purchaser's rights in law or equity to recover from Founder and
Sellers in respect of any claims of CORE or Purchaser not fully satisfied by
such offsets.

SECTION 7.5  NOTIFICATION

     To simplify notification and communications pursuant to this Article VII,
each Seller hereby appoints Founder to act as its agent and attorney-in-fact to
receive and deliver notices under this Article VII and to negotiate settlements
on its behalf. Accordingly, a notice by CORE or Purchaser to either Founder or
to any Seller shall be deemed to be a notice to each of Founder and all Sellers.
Similarly, an instruction notice, waiver or objection from either Founder or any
Seller shall be deemed to be an instruction, notice, waiver or objection from
each of Founder and all Sellers.

circumstances described in this Article X are reasonable.

                                   EXHIBIT A

                          TO ASSET PURCHASE AGREEMENT

                             PERFORMANCE CRITERIA

     Notwithstanding any other term or condition of the Asset Purchase Agreement
or this Exhibit A or any formula or description described herein, in no event
shall more than $920,000 ($600,000 maximum for Fiscal Period One and $320,000
for Fiscal Period Two) Additional Purchase Price consideration be due Sellers
for satisfaction of Financial Performance Criteria.

ADDITIONAL PURCHASE PRICE CONSIDERATION FOR FISCAL PERIOD ONE

     Additional Purchase Price consideration shall be made to the Sellers if the
following Financial Performance Criteria are met or exceeded by the Business of
the Purchaser for the periods indicated:
<TABLE>
<CAPTION>
 
 Quarter Ended       Target Pre-tax Net Income  Additional Purchase Price
 -------------       -------------------------  -------------------------
<S>                   <C>                      <C>
 
Fiscal Period One:
 
09/30/97                 $1,000,000                   $150,000
 
12/31/97                 $1,000,000                   $150,000
 
03/31/98                 $  825,000                   $150,000
 
06/30/98                 $  825,000                   $150,000
 
        TOTAL:           $3,650,000       TOTAL:      $600,000
 
</TABLE>

     For each quarter of Fiscal Period One, if Purchaser's Pre-tax Net Income
equals or exceeds 70% of the Target Pre-tax Net Income indicated, Sellers shall
be entitled to the Additional Purchase Price consideration indicated. If for any
quarter in Fiscal Period One, Purchaser's Pretax Net income is less than the
indicated Target Pre-tax Net Income and greater than 70%, then Sellers shall be
entitled to Additional Purchase price consideration in an amount equal to the
maximum quarterly Additional Purchase Price ($150,000) multiplied by a fraction,
the numerator of which is the actual Pre-Tax Net Income and the denominator of
which is the Target Pre-Tax Net Income. For example and without limitation, if
Purchaser's Pre-tax Net Income for the quarter ended 3/31/98 is $660,000 (80% of
the Target), the Additional Purchase Price consideration for such quarter shall
be $120,000 (80% of $150,000).

                                       
<PAGE>
 
     Furthermore, if less than $600,000 Additional Purchase Price consideration
is due or has been paid Sellers for the four quarters ended June 30, 1998,
Sellers shall receive Additional Purchase Price consideration, above the
quarterly Additional Purchase Price consideration, so that the percentage of the
$600,000 Additional Purchase Price consideration due Sellers is not less than
the percentage of (x) actual Pre-Tax Net Income plus Core Added Value (as
defined below) divided by (y) $3,650,000; provided no payment under this
sentence shall be due if the percentage is less than 70% for the entire four
quarter period.

     When earned, Additional Purchase Price consideration will be paid within 45
days following the end of the applicable quarter.

     For the purposes of this Agreement, Pre-tax Net Income is defined as all
Business revenues of Purchaser less all Business expenses of Purchaser excluding
interest expense and income taxes related to the Business operation.  Business
expenses of Purchaser include those expenses relating to the operation of the
Business of Purchaser (SSDC Corp.) and include without limitation, all direct
expenses, general and administrative expenses, sales and marketing expenses and
depreciation expense.

     CORE Added Value shall equal 10% of the amount of total first year sales
(exclusive of implementation fees and other direct cost reimbursement expenses)
of CORE's services or products (other than services and products of Sellers,
Purchaser or the Business) initiated within 24 months of the Closing Date and
made to an entity (i) which was a client of Sellers as of June 14, 1997, or (ii)
for which R. Gary Dolenga or SSDC Corp. acted as and was identified as the lead
sales contact and/or procuring cause.

     That portion of Additional Purchase Price consideration due to Sellers
based on CORE Added Value (i.e., first year sales to new CORE clients) shall be
earned, on the earlier of when a contract is signed between CORE and the new
client or when services actually begin; however, payment of such amount shall be
expressly contingent on receipt of payment(s) from the new client and payable to
Sellers within 45 days of such receipt.

     CORE shall deliver timely monthly financial statements to R. Gary Dolenga.
Such statements will be prepared in accordance with generally accepted
accounting principles (GAAP). R. Gary Dolenga shall have the right to audit or
review the financial statements at his expense.

ADDITIONAL PERFORMANCE CRITERIA

     For the purposes of the Employment Agreement between Purchaser and R. Gary
Dolenga, and for Additional Purchase Price Criteria for Fiscal Period Two, the
following are the Financial Performance Criteria to be met or exceeded by the
Business of Purchaser for the periods indicated:

LIMIT ON ADDITIONAL PURCHASE PRICE CONSIDERATION

or this Exhibit A or any formula or description described herein, in no event
shall more than $920,000 ($600,000 maximum for Fiscal Period One and $320,000
for Fiscal Period Two) Additional Purchase Price consideration be due Sellers
for satisfaction of Financial Performance Criteria.

     Under no circumstances shall the Quarterly Payments be reduced on account
of Financial Performance Criteria.

     3.  Exercise.
         -------- 

         3.1  Exercisability.  Subject to vesting and the terms and conditions
              -------------- 
of this Agreement, the Option may be exercised by Holder with respect to all or
any portion of the shares of common stock covered by the Option at any time on
or after the date hereof; provided that the Option may not be exercised at any
one time with respect to less than one hundred (100) shares of common stock of
CORE, unless the number of shares with respect to which the Option is exercised
is the total number of shares with respect to which the Option is exercisable at
that time.
<PAGE>
 
         3.2  Notice of Exercise.  Holder shall exercise the Option by
              ------------------   
delivering to CORE, either in person or by certified or registered mail, written
notice of election to exercise and payment in full of the purchase price as
provided in Subsection 3.3 below. The written notice shall set forth the whole
number of shares with respect to which the Option is being exercised.

         3.3  Payment of Purchase Price.  (a) The purchase price for any shares
              -------------------------  
of common stock with respect to which Holder exercises this Option shall be paid
in full at the time Holder delivers to CORE the written notice of election to
exercise. Except as provided in 3.3(b), the purchase price shall be paid in cash
or by check.

              (b) Notwithstanding any provisions herein to the contrary, if the
Current Market Value of one share of Common Stock of CORE is greater than the
Exercise Price for one share of Underlying Common Stock (at the date of the
calculation as set forth below), in lieu of paying the Exercise Price in cash,
the Holder may elect to receive shares of Underlying Common Stock equal to the
value (as determined below) of this Option (or the portion thereof being
exercised) by surrender of this Option at the principal office of CORE together
with a properly completed Notice in the form attached hereto as Exhibit A, in
                                                                --------- 
which event CORE shall issue to the Holder that number of shares of underlying
Common Stock computed using the following formula:

                    UCS  =    UWCS (CMV-EP)
                              -------------
                                  CMV

              Where

                    UCS  =    the number of shares of Underlying Common Stock to
                              be issued to the Holder.

                    UWCS =    the number of shares of Underlying Common Stock
                              purchasable under this Option, or, if only a
                              portion of this Option is being exercised, the
                              portion of this Option being exercised and
                              canceled (at the date of such calculation).

                    CMV  =    the Current Market Value of one share of
                              Underlying Common Stock (at the date of such
                              calculation).

                    EP   =    the per share Exercise Price (as adjusted to the
                              date of such calculation).

     Underlying Common Stock means the shares of Common Stock of CORE subject to
this Option.

                                       2
<PAGE>
 
     Current Market Value means, at the date of determination, the closing price
per share of Common Stock of CORE on the trading date immediately preceding the
date of such determination, as such closing price is reported on the Nasdaq
National Market or, if the Common Stock is not then traded on the Nasdaq
National Market, on such other exchange or market on which the Common Stock is
then traded.


         3.4  Vesting.  This Option shall be 50% exercisable on June 14, 1988
              -------                                                   
(one year from the Grant Date) and 100% exercisable on June 14, 1999 (two years
from the Grant Date). The June 14, 1999 vesting of the second 50% is contingent
upon R. Gary Dolenga's continued employment with CORE or a CORE subsidiary
through June 14, 1999, provided termination of employment due to disability or
without "Cause" (as defined in the Employment Agreement between R. Gary Dolenga
and SSDC Corp.) shall not prevent vesting pursuant to this sentence. This Option
shall be 100% exercisable upon a "Change in Control" of CORE, as defined in
Section 10.6 hereof, during R. Gary Dolenga's employment with CORE or a CORE
subsidiary. Subject to earlier termination events, this Option shall be
exercisable as follows:

         3.5  Earlier Termination Events.  Notwithstanding the scheduled
              --------------------------                                
expiration date set forth in Section 2, this Option shall terminate (i)
immediately upon termination of the Asset Purchase Agreement pursuant to Article
X thereof; or (ii) on September 30, 1997 or such later date as determined by
CORE in its sole discretion if (A) the Closing under the Asset Purchase
Agreement has not occurred, or (B) R. Gary Dolenga has not executed an
Employment Agreement with SSDC Corp. prior to such date.

     4.   Issuance of Shares.  Promptly after CORE's receipt of the written
          ------------------                                               
notice of election provided for in Subsection 3.2 above and Holder's payment in
full of the purchase price pursuant to Section 3.3(a) or (b), CORE shall
deliver, or cause to be delivered to Holder certificates for the whole number of
shares with respect to which the Option is being exercised by Holder.  Shares
shall be registered in the name of the Holder.

     5.  No Fractional Shares.  In no event shall CORE be required to
         --------------------                                        
issue fractional shares upon the exercise of any portion of the Option.

<PAGE>
 
     6.  Rights as Stockholder.  Holder shall have no rights as a
         ---------------------                                   
stockholder of CORE with respect to any shares covered by the Option until the
date of exercise of an Option for such shares.  No adjustment shall be made for
dividends (ordinary or extraordinary, whether cash, securities, or other
property) or distributions or other rights for which the record date is prior to
the date such share certificate is issued, except as provided in Section 7
below.

     7.   Recapitalization or Reorganization of CORE.  Except as otherwise
          ------------------------------------------                      
provided herein, appropriate and proportionate adjustments shall be made in the
number and class of shares subject to the Option and the purchase price of such
shares in the event of a stock dividend, stock split, reverse stock split,
recapitalization, reorganization, merger, consolidation, separation, or like
change in the capital structure of CORE.  In the event of a liquidation of CORE
or a merger, reorganization, or consolidation of CORE with any other corporation
in which CORE is not the surviving corporation or CORE becomes a subsidiary of
another corporation, or the sale of substantially all other assets of CORE or
more than 50 percent of the then outstanding stock of CORE to another
corporation or entity, any unexercised portion of the Option shall be deemed
cancelled unless the surviving corporation in any such merger, reorganization,
or consolidation elects to assume the Option or to issue substitute options in
place thereof.  Notwithstanding the foregoing, if the Option otherwise would be
cancelled in accordance with the preceding sentence, Holder shall receive
advance notice of at least 30 days and have the right, exercisable during a
thirty (30) day period ending on the fifth (5th) day prior to such liquidation,
merger, consolidation, sale of assets or change of control, to exercise the
Option in whole or in part.  Such exercise may be contingent upon the closing of
the proposed transaction and revocable by Holder if such transaction does not
close.  Additionally, for the purposes of the foregoing three sentences, such
transaction shall be deemed to be a "Change in Control" upon Holder's exercise
of this Option even if such exercise is prior to the actual closing of the
transaction.  To the extent that the foregoing adjustments relate to stock or
securities of CORE, such adjustments shall be made by the Board, the
determination of which shall be final, binding, and conclusive.

     8.   Permitted Transfer of Option.  This Option shall not be
          ----------------------------                           
assignable or transferable, provided, however, this Option may be transferred to
the spouse or issue of Holder, the legal representative of any trust or estate
in which the Holder or his or her spouse or issue shall have the principal
beneficial interest, or any charitable remainder trust.  In order for the
transfer to be effective, transferee and CORE shall execute a new Option
Agreement with the same terms and provisions as this Agreement.

     9.   Investment Representation.  Holder hereby represents and Options
          -------------------------                                       
to CORE that Holder is acquiring the Option and the common stock subject thereto
for Holder's own account and not with a view to or for sale in connection with
any distribution thereof.  Holder hereby further represents and Options to, and
agrees with, CORE that, if Holder exercises the Option in whole or in part at a
time when there is not in effect under the Securities Act of 1933, as amended, a
registration statement covering the shares issuable upon exercise of the Option
and available for delivery a prospectus meeting the requirements of Section
10(a)(3) of said Act, that Holder may be required, as a condition of issuance of
the shares of common

                                       4
<PAGE>
 
stock of CORE covered by the Option, to represent to CORE that the shares issued
pursuant to the exercise of the Option are being acquired for investment and
without a view to distribution thereof; and that in such case CORE may place a
legend on the certificate(s) evidencing the shares of the common stock of CORE
issued upon exercise of the Option reflecting the fact that the shares were
acquired  for investment and cannot be sold or transferred unless registered
under said Act or unless counsel for CORE is satisfied that the circumstances of
the proposed transfer do not require such registration.

     10.  Option not an Incentive Stock Option.  CORE and the Holder acknowledge
          ------------------------------------                      
and agree that the Option is not and shall not be construed to be an "Incentive
Stock Option" (as such term is defined under (S)422 of the Internal Revenue Code
of 1986, as amended.

     11.  General Provisions.
          ------------------

          (b)   Executive agrees that for a period commencing with the date of
this Agreement and ending on the Covenant End Date:

                (i)   Executive will not directly or indirectly solicit, hire or
attempt to hire for any purpose whatsoever (whether as an employee, consultant,
advisor, independent contractor or otherwise) any employee or consultant of
Company and its Affiliates or any person who was an employee or consultant of
any such corporations (and will use best efforts to prevent any subsequent
employer of Executive or related entity or person from taking any such actions);

                (ii)  Executive will not induce or attempt to induce any
customer, client supplier, licensee or other business relation of Company and
its Affiliates to cease doing business with Company and its Affiliates, or in
any way interfere with the relationship or potential relationship between any
such customer, client, supplier, licensee or business relation and Company and
its Affiliates; and

                (iii) Executive shall not solicit or attempt to solicit, or
accept business from, any entity which at any time during the twelve month
period prior to the date of termination of Executive's employment with Company
and its Affiliates, was a client or customer of Company and its Affiliates, for
the purpose of doing business with such client or customer in competition with
Company and its Affiliates. For the purpose of this covenant, the clients and
customers of Company and its Affiliates shall include those entities with which
Company and its Affiliates had held discussions or negotiations concerning
services of Company and its Affiliates.

          (c)  Injunctive Relief.  Without intending to limit the remedies
               -----------------                                          
available to Company and its Affiliates, Executive acknowledges that a breach of
any of the covenants contained in this Agreement could result in material
irreparable injury to Company and its Affiliates for which there might be no
adequate remedy at law, and that, in the event of such a breach or threat
thereof, Company shall be entitled to obtain a temporary restraining order
and/or a preliminary and permanent injunction restraining Executive from
engaging in any activities prohibited by this Agreement or such other equitable
relief as may be required to enforce specifically any of the covenants of this
Agreement.

          (d)  Nothing herein contained shall prevent Executive from holding or
making an investment in securities listed on a national securities exchange or
sold in the over-the-counter

                                       5

market, provided that such investments do not exceed in the aggregate five
percent (5%) of the issued and outstanding capital stock of a corporation which
is a competitor within the meaning of this Section.

          (e)  Confidential Information.  Executive acknowledges that the
               ------------------------                                  
Confidential Information (as defined below) relating to the business of the
Company and its Affiliates which Executive has obtained or will obtain during
the course of his association with the Company (including, without limitation,
Executive's association with entities that are parties to the Asset Purchase
Agreement) is the property of the Company and its Affiliates.  Executive agrees
that he will not disclose or use at any time, either during or after his
employment with the Company, any Confidential Information without the written
consent of the Board of Directors of the Company (the "Board").  Executive
agrees to deliver to the Company upon termination of his employment with the
Company, or at any other time the Company may request, all memoranda, notes,
plans, records, documentation and other materials (and copies thereof)
containing Confidential Information relating to the business of the Company and
its Affiliates no matter where such material is located and no matter what form
the material may be in, which Executive may then possess or have under his
control.  If requested by the Company, Executive shall provide the Company with
written confirmation that all such materials have been delivered to the Company.
Executive shall take all appropriate steps to safeguard Confidential Information
and to protect it against disclosure, misuse, espionage, loss and theft.

          (f)  Definition of "Confidential Information".  "Confidential
               ----------------------------------------                
Information" shall mean proprietary information which is not generally known
within the health care, disability management or government advocacy industries
and which is used, developed, or obtained by the Company and its Affiliates
(including acquisition of such information pursuant to the Asset Purchase
Agreement) relating to its business and its customers' businesses including, but
not limited to: services or products; fees, costs and pricing structure;
designs; analyses; drawings; photographs; reports; computer software, manuals
and documentation; data bases; business and operating plans; accounting and
business methods; budgets; inventions and new developments and methods, whether
patentable or unpatentable and whether or not reduced to practice; formulas; all
copyrightable works; the customers of the Company and its Affiliates and the
customers' Confidential Information; and all similar and related information in
whatever form.

                                       6
<PAGE>
 
Confidential Information shall not include any information which (i) is publicly
disclosed by law or in response to an order of a court or governmental agency,
(ii) becomes publicly available through no fault of Executive, or (iii) has been
published in a form generally available to the public prior to the date upon
which Executive proposes to disclose such information.  Information shall not be
deemed to have been published merely because individual portions of the
information have been separately published, but only if all the material
features comprising such information have been published in combination.

          (g)  The parties are of the view that the restrictions placed on
Executive herein, in the light of all the circumstances (including, without
limitation the closing of the Asset Purchase Agreement), are reasonable as to
scope, period of time and geographical area.  Nevertheless, it is the intent of
the parties that this Agreement be enforceable and restrict Executive's
activities only to the extent permitted by law.  Accordingly, in the event that
any provisions in this Agreement shall be determined by arbitrators or by any
court of competent jurisdiction to be unenforceable by reason of its extending
for too great a period of time over too large a geographic area or range of
activities, it shall be interpreted to extend only over the maximum period of
time, geographic area or range of activities as to which it may be enforceable.

          (h)  Definition of "Company and its Affiliates".  For the purposes of
               ------------------------------------------                      
Sections 9 and 10, "Company and its Affiliates" shall mean Company, CORE, INC.,

         ---------------                                              
Executive shall not be entitled to retain any records or charts of Company and
its Affiliates in his possession.

     11. Arbitration.  Except for equitable remedies set forth in Section 9
         -----------                                                       
hereof, and except for disputes in excess of $100,000, any controversy or claim
arising under or relating to this Agreement, or breach thereof, shall be settled
by arbitration in Orange County, California in accordance with the rules of the
American Arbitration Association as in effect from time to time.  Judgment upon
the award rendered may be entered in any court having jurisdiction thereof.

     12. Assignability.  This Agreement shall inure to the benefit of the
         -------------
