Material Adverse Effect.

copies of the Organizational Documents of each Entity and each Seller, in each

Agreement and each Related Document, the performance by either Seller of its
obligations under this Agreement and each Related Document to which it is or

thereby, does or will (a) result in the creation of an Encumbrance upon any

licensees and operations as an ongoing business and preserve its goodwill, in
accordance with past custom and practice and (ii) to satisfy each of the closing
conditions to be satisfied by it set forth in Article VII hereof; and

        (s) pay and continue to defer all accounts payable and all expenses in a
manner which is consistent with past practices and in the ordinary course of
business.

6.3      EFFORTS TO CONSUMMATE.

         Subject to the terms and conditions of this Agreement, each party
shall use commercially reasonable efforts to take or cause to be taken all
actions and do or cause to be done all things required under all applicable
Laws, in order to consummate the transactions contemplated hereby.

6.4      NO SOLICITATION.

        (a) The Parent shall, shall cause M Sub and each Entity to and shall
direct and cause its and each such Person's officers, directors, employees,
representatives and agents to, immediately cease any discussions or negotiations
with any parties (other than the Purchasers and Alliance) that may be ongoing
with respect to an Alternative Transaction. The Parent shall not, shall cause M
Sub and each Entity not to and shall not authorize or permit any of its or any
such Person's officers, directors or employees or any investment banker,
financial advisor, attorney, accountant or other representative representing any
such Person to, directly or indirectly, (i) solicit, initiate or encourage
(including by way of furnishing information), or take any other action to
facilitate, any inquiries or the making of any proposal that may lead to an
Alternative Transaction or (ii) participate in any discussions or negotiations
regarding any proposed Alternative Transaction; provided, however, that if, at
any time prior to the Closing Date, the Board of Directors of the Parent
determines in good faith, based on written advice from outside counsel, that
action is required by reason of such Board of Directors' fiduciary duties to the
Parent's stockholders under applicable law, the Parent may (subject to
compliance with Section 6.4(c)), in response to an unsolicited Third Party
Proposal, (A) furnish information with respect to the Parent and the Entities to
the Person making such Third Party Proposal pursuant to a confidentiality
agreement that is at least as protective of the Parent's and its Subsidiaries'
interests as is the Confidentiality Agreement and (B) participate in
negotiations regarding such a Third Party Proposal. Without limiting the



                                       29
   31

foregoing, it is understood that any violation of the restrictions set forth in
the preceding sentence by any director, officer or employee of the Parent, M Sub
or any Entity or any investment banker, financial advisor, attorney, accountant
or other representative acting on behalf of any such Person shall be deemed to
be a breach of this Section 6.4(a).

        (b) Neither the Board of Directors of the Parent nor any committee
thereof shall (i) withdraw or modify the approval or recommendation by such
Board of Directors or such committee of this Agreement, the Related Documents or
any of the transactions contemplated hereby or thereby, (ii) approve or
recommend any Alternative Transaction or (iii) cause or permit the Parent, M Sub
or any Entity to enter into any letter of intent, agreement in principle,
acquisition agreement or other agreement (an "Acquisition Agreement") with
respect to an Alternative Transaction unless the Board of Directors of the
Parent shall have previously terminated this Agreement pursuant to Section
9.1(f).

        (c) In addition to the obligations of the Parent set forth in paragraphs
(a) and (b) of this Section 6.4, the Parent shall immediately advise the
Purchasers orally and in writing of any request for information or of any
proposal or any inquiry regarding any Alternative Transaction, the material
terms and conditions of such request, proposal or inquiry and the identity of
the Person making such request, proposal or inquiry. The Parent will keep the
Purchasers fully informed of the status and details (including amendments or
proposed amendments) of any such request, proposal or inquiry.

        (d) Nothing contained in this Section 6.4 shall prohibit the Parent from
at any time taking and disclosing to its stockholders a position contemplated by
Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act or from making any
disclosure to the Parent's stockholders, in each case with respect to any Third
Party Proposal, if the Parent shall have provided the Purchasers with as much
advance notice of its position and proposed disclosure as is possible under the
circumstances; provided, however, that neither the Parent nor its Board of
Directors nor any Committee thereof shall, except as permitted by Section
6.4(b), withdraw or modify, or propose to withdraw or modify, its position with
respect to this Agreement, the Related Documents or any of the transactions
contemplated hereby or thereby or approve or recommend, or propose to approve or
recommend, an Alternative Transaction.

6.5      CONFIDENTIALITY.

         The Sellers and the Purchasers agree that, through and including the
Closing Date, they shall comply with that certain letter agreement relating to
matters of confidentiality dated as of July 24, 1997 (as amended, modified or
supplemented, the "Confidentiality Agreement").

6.6      NOTICE OF PROSPECTIVE BREACH.

         Each party shall immediately notify the other parties in writing upon
the occurrence, or failure to occur, of any event, which occurrence or failure
to occur would be reasonably likely to cause any representation or warranty of
such party that is contained



                                       30
   32

in this Agreement or any Related Document to be untrue or inaccurate in any
material respect at any time from the date of this Agreement to the Closing.

6.7      PUBLIC ANNOUNCEMENTS.

         Each party agrees that, except (i) as otherwise required by Law or
Order and (ii) for disclosure to its respective directors, officers, employees,
financial advisors, potential financing sources, legal counsel, independent
certified public accountants or other agents, advisors or representatives on a
need-to-know basis and with whom such party has a confidential relationship, it
will not issue any reports, statements or releases, in each case pertaining to
this Agreement or any Related Document to which it is a party or the
transactions contemplated hereby or thereby, without consulting in advance with
the other parties hereto.

6.8      COOPERATION REGARDING TAX FILINGS; SECTION 338(h)(10).

        (a) After the Closing, the Purchasers and the Sellers shall act in good
faith and cooperate with one another for the purpose of filing all Tax Returns
and reports required to be filed by any of them. Parent shall join Purchaser A
in a timely election pursuant to Section 338(h)(10) of the Code (and under any
comparable provision of any state or local law) with respect to the CT Shares
(the "338(h)(10) Election"). The parties hereto recognize that the 338(h)(10)
Election will result in the purchase of the CT Shares hereunder being treated as
a sale of assets by CT Sub for Federal income Tax purposes and for applicable
state and local tax purposes and that any Tax Liability arising with respect to
the 338(h)(10) Election (other than a Liability for Transfer Taxes described in
Section 10.14) shall be deemed a Covered Tax. None of the parties hereto shall
make any Tax Return or other filing that is inconsistent with the foregoing.

        (b) The Purchasers shall be responsible for the preparation and filing
of all 338(h)(10) Election forms and the Sellers shall execute and deliver to
Purchasers such documents as are reasonably requested to properly complete such
forms at least twenty (20) days prior to the date such 338(h)(10) Election is
required to be filed. The Sellers agree that the Purchasers shall be entitled to
determine the allocation of the Modified Aggregate Deemed Sales Price (as
defined in the treasury regulations promulgated under Section 338 of the Code)
among the assets of CT Sub in their sole discretion, and in accordance with
Section 338 of the Code and the regulations thereunder (including the allocation
of any adjustment to the Modified Aggregate Deemed Sales Price by reason of any
purchase price adjustment or indemnification payment under this Agreement), and
shall notify the Sellers of such determination as soon as possible after making
such determination. The Purchasers and the Sellers agree to act in accordance
with any such allocation in all relevant Tax Returns and filings.

        (c) Parent shall cause to be prepared and cause to be timely filed all
consolidated, combined or unitary federal, state, local or foreign Tax Returns
required to be filed with respect to Parent for all taxable periods ending
before or including the Closing Date and shall include CT Sub in all such
returns in which it is eligible to be



                                       31
   33

included. The Purchasers agree to cooperate with Parent and its Affiliates in
the preparation of the portions of such Tax Returns pertaining to CT Sub. The
Parent shall permit the Purchasers to review and comment on the portion of all
Tax Returns prepared by Parent pursuant to this Section 6.8(c) pertaining to CT
Sub, or the Partnership prior to the filing of such Tax Returns. Parent shall
cause to be timely paid all Taxes to which such Tax Returns relate for all
periods covered by such Tax Returns.

        (d) The extent to which Taxes of CT Sub and the Partnership for a
taxable period that includes but does not end on the Closing Date are treated as
Taxes for the period ending on or prior to the Closing Date shall be determined
for all purposes, including for purposes of calculating Covered Taxes, as
follows: (i) Taxes measured in whole or in part by net or gross income and Taxes
relating to specific transactions shall be apportioned on the basis of a closing
of the books of the Entity liable for such Tax at the close of business on the
Closing Date; provided, however, that all transactions not in the ordinary
course of business and not contemplated in this Agreement that occur on the
Closing Date after Purchaser A's purchase of the CT Shares shall be reported on
Purchaser A's federal income tax return to the extent permitted by Treas. Reg.
Section 1502-76(b((1)(3); and (ii) all other Taxes shall be prorated according
to the ratio of the number of days in such taxable period prior to and including
the Closing Date to the number of days in such taxable period.

        (e) The Sellers shall cause to be prepared all required federal, state,
local and foreign Tax Returns of CT Sub and the Partnership for any period which
ends on or before the Closing Date, for which Tax Returns have not been filed as
of the Closing Date (other than Tax Returns to be filed by Parent pursuant to
Section 6.8(c)). The Purchasers shall cause to be prepared and cause to be
timely filed all required federal, state, local and foreign Tax Returns of CT
Sub and the Partnership (other than Tax Returns to be filed by Parent pursuant
to Section 6.8(c)) for taxable periods beginning before and ending after the
Closing Date. The Sellers and Purchasers agree to cooperate with each other in
the preparation of such Tax Returns. The Purchasers shall permit Sellers to
review and comment on all Tax Returns prepared by the Purchasers pursuant to
this Section 6.8(e) and such Tax Returns shall be subject to the prior approval
of the Sellers which approval shall not be unreasonably withheld. The Sellers
shall permit the Purchasers to review and comment on all Tax Returns prepared by
the Sellers pursuant to this Section 6.8(e). Prior to the date such Tax Returns
are due, the Parent will provide the Purchasers with amounts equal to the
Covered Taxes, as shown on the Tax Returns to be filed under this Section
6.8(e), after taking into account any Tax or estimated Tax paid with respect to
such Covered Taxes prior to the Closing Date. Promptly after receipt by the
Purchasers of the amounts in respect of the Covered Taxes from the Parent, the
Purchasers will cause the applicable Tax Returns prepared by the Seller to be
filed.

        (f) Parent shall be entitled to any refund of Taxes paid by or with
respect to CT Sub that is attributable to taxable periods ending on or prior to
the Closing Date, and the Purchasers shall cause CT Sub to pay over to Parent
any such refunds (net of any Tax Liability attributable thereto and any expenses
incurred in the collection of such refund)



                                       32
   34

within fifteen (15) days after receipt thereof. If the amount of such refund
that is paid over by Parent is subsequently reduced by a Governmental Entity,
Parent shall pay to Purchasers an amount necessary to reflect such adjustment.

        (g) The Parent shall not file any claim for a refund or credit, or an
amended return claiming a refund or credit, after the Closing Date, for any Tax
paid by CT Sub without the prior written consent of the Purchasers, which
consent shall not be unreasonably withheld.

        (h) Each of the Purchasers and the Sellers shall promptly notify the
other party upon receipt of a notice of any pending or threatened Tax audit or
assessment (a "Tax Claim") that may affect the Tax Liabilities of CT Sub, or the
Partnership and for which any Seller would be liable under this Agreement;
provided, however, that no delay on the part of either party in so notifying the
other party shall relieve the other party from any liability or obligation
hereunder (unless, and then solely to the extent) that the other party is
materially and irrevocably prejudiced by such delay. Such notice shall be
accompanied by copies of all relevant documentation with respect to such Tax
Claim.

        (i) If the Sellers shall acknowledge in a writing delivered to the
Purchasers that such Tax Claim is properly subject to their indemnification
obligations hereunder and the Sellers shall have the financial resources to meet
such indemnification obligations, then subject to the further provisions of this
Section 6.8(i), the Sellers shall have the right to assume the defense of such
Tax Claim at their own expense and by their own counsel and other advisers,
which counsel and other advisors shall be reasonably satisfactory to the
Purchasers; provided, however, that the Sellers shall not have the right to
assume the defense of any Tax Claim, notwithstanding the giving of such written
acknowledgment, if the Sellers shall not have assumed the defense of such Tax
Claim in a timely fashion. Notwithstanding anything to the contrary contained
herein, if a Tax Claim involves, or could have a material effect on any material
matter beyond the scope of the indemnification obligations of the Sellers, the
Sellers and Purchasers shall jointly assume the defense of such Tax Claim at
their own expense. If the Sellers exercise their right to assume the defense of
a Tax Claim pursuant to and in accordance with this Section 6.8(i), (i) the
Purchasers shall be entitled to participate in such defense with their own
counsel and other advisors at their own expense, (ii) the Purchasers will
reasonably cooperate with the Sellers and their counsel and advisors in the
defense of such Tax Claim, and (iii) the Sellers shall not make any settlement
of such Tax Claim without the written consent of the Purchasers, which consent
shall not be unreasonably withheld, provided that consent may be withheld if any
Losses to be incurred by the Purchasers pursuant to such settlement are not
indemnified pursuant to the indemnification provisions set forth in Article VIII
hereunder.

        (j) If the Sellers shall assume the defense of a Tax Claim pursuant to
and in accordance with Section 6.8(i), the Sellers shall not be responsible for
any legal or other defense costs subsequently incurred by the Purchasers in
connection with the defense thereof. If the Sellers do not exercise their right
to assume the defense of a Tax Claim or



                                       33
   35

are otherwise restricted from doing so pursuant to Section 6.8(i), the Sellers
shall nevertheless be entitled to participate in such defense with their own
counsel and other advisors at their own expense. If the defense of a Tax Claim
is retained by the Purchasers, the Purchasers shall not be entitled to settle
such Tax Claim without the prior written consent of the Sellers, which consent
shall not be unreasonably withheld.

        (k) After the Closing Date, the Sellers and the Purchasers shall make
available to the other, as reasonably requested, all information, records or
documents relating to Tax Liabilities or potential Tax Liabilities of CT Sub or
the Partnership for all periods ending on or prior to the Closing Date, and
shall preserve all such information, records and documents until the expiration
of any applicable statute of limitations or extensions thereof.

        (l) All Tax Returns which are required to be prepared by Sellers
pursuant to Sections 6.8(c) and (e) shall be prepared and filed in a manner
consistent with past practice and applicable Law and, on such Tax Returns, no
position shall be taken, elections made or method adopted that is inconsistent
with positions taken, elections made or methods used in preparing and filing
similar Tax Returns in prior periods.

6.9      EXCHANGE PROCEEDS.

         If, between the date hereof and the Closing, any Entity or any Seller
receives any proceeds in consideration for the exchange of any of its assets
(solely, in the case of the Parent as it relates to the Purchased Parent
Assets), whether from the sale of any such assets, from insurance proceeds
payable on account of any loss or casualty to such assets, any proceeds from
the taking of such assets pursuant to the power of eminent domain, or any other
proceeds from whatever source relating to the disposition of such assets (the
"Exchange Proceeds"), the Sellers shall immediately notify the Purchasers of
the receipt of such Exchange Proceeds and shall consult with the Purchasers
with respect to the application of any such Exchange Proceeds.  The Sellers
shall ensure that any Exchange Proceeds received by any Entity shall either be
used to purchase replacement assets or shall be retained by the applicable
Entity.

6.10     NON-COMPETE; NON-SOLICITATION.

        (a) During the Non-Compete Period, the Parent shall not, and cause its
Affiliates not to, directly or indirectly, own, manage, control, participate in,
consult with, render services for, or in any manner engage in or represent any
business within any Restricted Territory that is competitive with the Business
or any product or services of the Business as such Business is conducted or
proposed to be conducted from and after the Closing Date; provided, however,
that nothing herein shall be deemed to prevent the Parent or any of its
Affiliates from engaging in any activities presently conducted or proposed to be
conducted by GK Finance or from providing any imaging modality as part of its
"Operating Room of the Twenty First Century" business.



                                       34
   36

        (b) During the Non-Compete Period, none of the Parent nor any Affiliate
shall directly or indirectly through another Person (i) induce or attempt to
induce any employee of any Purchaser or any Affiliate of such Purchaser to leave
the employ of such Purchaser or such Affiliate or in any way interfere with the
relationship between such Purchaser or any such Affiliate, on the one hand, and
any employee thereof, on the other hand, or (ii) induce or attempt to induce any
customer, supplier, licensee or other business relation of any Purchaser or any
Affiliate of such Purchaser to cease doing business with such Person or in any
way interfere with the relationship between any such customer, supplier,
licensee or business relation, on the one hand, and such Person, on the other
hand.

        (c) If, at the time of enforcement of this Section 6.10, a court holds
that the restrictions stated herein are unreasonable under the circumstances
then existing, the parties agree that the maximum period, scope or geographical
area reasonable under such circumstances shall be substituted for the stated
period, scope or area. The parties hereto acknowledge that money damages would
be an inadequate remedy for any breach of this Section 6.10. Therefore, in the
event of a breach or threatened breach of this Section 6.10, the Purchasers or
their successors or assigns may, in addition to other rights and remedies
existing in their favor, apply to any court of competent jurisdiction for
specific performance and/or injunctive or other relief in order to enforce, or
prevent any violations of, the provisions of this Section 6.10.

6.11     CERTAIN TAX MATTERS.

         From the date hereof until the Closing Date, (i) the Parent shall and
shall cause each Entity to file all tax returns and reports ("Post-Signing
Returns") required to be filed in a manner consistent with past practices; (ii)
the Parent shall and shall cause each Entity to timely pay all Taxes shown as
due and payable on the Post-Signing Returns; (iii) the Parent shall and shall
cause each Entity to make provision for all Taxes payable for which no
Post-Signing Return is due prior to the Closing Date; (iv) the Parent shall
allow the Purchasers an opportunity to review and comment on any Post-Signing
Return prior to the due date of such Post-Signing Return; and (v) the Parent
will promptly notify the Purchasers of any action, suit, proceeding, claim or
audit pending against or with respect to the Parent or any Entity in respect of
any Tax where there is a possibility of a determination or decision which could
have an adverse effect on the Parent's or any Entity's Tax Liabilities or Tax
attributes.

6.12     ADVICE OF CHANGES; FILINGS.

         The Parent shall confer with the Purchasers on a regular and frequent
basis as reasonably requested by the Purchasers, report on operational matters
and promptly advise the Purchasers orally and, if requested by the Purchasers,
in writing of any change with respect to the Parent or any Entity.  The Parent
shall promptly provide to the Purchasers (or their counsel) copies of all
filings made by the Parent or any Entity with any



                                       35
   37

Governmental Entity in connection with this Agreement and the transactions
contemplated hereby.

        (a) The Parent will, as soon as practicable following the date hereof,
duly call, give notice of, convene and hold a meeting of its stockholders (the

Agreement, the Related Documents, and the transactions contemplated hereby and
thereby. The Parent will, through its Board of Directors, recommend to its
stockholders that the Parent Stockholder Approval be given.

        (b) The Parent will, as soon as practicable following the date hereof,
prepare and file a preliminary proxy or information statement (as amended,

best efforts to respond to any comments of the SEC or its staff and to cause the
Proxy Statement to be mailed to its stockholders as promptly as practicable
after responding to all such comments to the satisfaction of the SEC staff. The
Proxy Statement shall contain the written opinion of Paine Webber Incorporated,
opining as to the matters set forth in Section 3.25. The Parent will afford the
Purchasers opportunity to review and comment upon any description of the
Purchasers or their Affiliates, this Agreement, the Related Documents or the
transactions contemplated hereby and thereby set forth in the Proxy Statement
(including all drafts or amendments thereto). Each Purchaser shall provide the
Parent with all necessary information reasonably requested with respect to
itself and Alliance solely for inclusion by the Parent in the Proxy Statement.
The Parent will notify the Purchasers promptly of the receipt of any comments
from the SEC or its staff and of any request by the SEC or its staff for
amendments or supplements to the Proxy Statement or for additional information
and will supply the Purchasers with copies of all correspondence between the
Parent or any of its representatives, on the one hand, and the SEC or its staff,
on the other hand, with respect to the Proxy Statement. If at any time prior to
the Stockholders Meeting there shall occur any event that should be set forth in
an amendment or supplement to the Proxy Statement, the Parent will promptly
prepare and mail to its stockholders such an amendment or supplement.

6.13     MAINTENANCE OF CASH AND CASH EQUIVALENTS.

         During the period commencing on the Closing Date and ending on April
15, 1999, the Parent shall at all times hold cash or Cash Equivalents of not

6.14     FURTHER ASSURANCES.

         The Sellers shall and shall cause the Entities to take such further
actions or execute such further documents or instruments as shall be reasonably
requested by the Purchasers



                                       36
   38

to further implement the transactions contemplated by Section 1.2 including,
without limitation, discharging or disposing of any Excluded Liability which may
be a Liability of any Entity on terms reasonably satisfactory to the Purchasers.

6.15     AUDITED FINANCIAL STATEMENTS.

         The Parent shall, and shall cause each of its Subsidiaries to, provide
the Purchasers and their advisors with such information (including, without
limitation, consolidating balance sheets and statements of operations as at
December 31, 1997 and for the fiscal year then ended; such consolidating
financial statements to incorporate the Entities in such form as presented in
Schedule 3.5(b) as well as individual columns for each of GK Finance, Parent
and each other Subsidiary of the Parent, in each case, as adjusted to give
effect to the transactions contemplated by Section 1.2 hereof), and access to
its books and records (including, without limitation, access to its management
employees), to permit them or their advisors to prepare audited balance sheets
of the Entities as of December 31, 1997, and related audited statements of
operations, shareholders' equity and cash flows for the period then ended, in
each case in accordance with GAAP and adjusted to give effect to the

6.16     DVI FUNDED INDEBTEDNESS.

         At the request of the Purchasers, on the Closing Date, the Parent
shall and shall cause its Subsidiaries to repay all Funded Indebtedness held by

Partnership Interests to Purchaser A in accordance with Section 1.1 hereof.

6.18     CERTAIN EMPLOYEE MATTERS.

        (a)         On the Closing Date, the Purchasers shall or shall cause
the Entities or an Affiliate of the Purchasers, to continue the employment of
or offer employment, as applicable, to the employees of the Entities and Parent
to be identified by the Purchasers



                                       37
   39

prior to the Closing Date in accordance with the terms of a letter, dated of
even date herewith, delivered by Purchaser A to the Parent (any such employees
who so continue or accept such offer of employment being referred to herein as
the "Hired Employees"). Such employment shall be in a substantially similar
position as such Hired Employee held while employed by the applicable Entity or
Parent prior to the Closing, and the Purchasers shall have no Liability or
obligation to any other employees of the Parent or any of its Subsidiaries
(other than the Entities as set forth herein). Prior to the Closing, Parent and
the Entities shall take such actions and, after the Closing Date, Parent and the
Purchasers shall take, and the Purchasers shall cause the Entities to take, such
actions as are necessary so that each Hired Employee shall cease to be entitled
to participate in or accrue benefits under any of Parent's Employee Benefit
Plans, programs, policies and arrangements except to the extent required by
applicable Law. The Purchasers shall, or shall cause the Entities or an
Affiliate of the Purchasers, to take such actions as may be necessary such that,
subject to the provisions of this Section 6.18, on and after the Closing Date,
each Hired Employee shall be eligible to participate in, and be subject to the
provisions of, the Employee Benefit Plans (including a 401(k) plan and a
flexible benefits plan), programs, personnel policies and guidelines sponsored
or maintained by Alliance, and applicable for employees of Alliance or its
Affiliates in a similar position, subject to the satisfaction of all the
eligibility criteria for participation thereunder (except as otherwise provided
in this Section 6.18).

        (b) With respect to the Alliance Employee Benefit Plans, programs,
personnel policies and guidelines, Alliance shall grant all Hired Employees from
and after the Closing Date credit for all service with the Entities and Parent
prior to the Closing Date for all purposes. Alliance shall take such actions as
are necessary to provide that on the Closing Date all Hired Employees and their
spouses and dependents shall be immediately covered by the group health plan
maintained by Alliance which shall (i) provide immediate coverage as of the
Closing Date without any waiting period, (ii) waive any pre-existing condition
exclusions or limitations, and (iii) provide that any amounts paid by Hired
Employees through the Closing Date for medical expenses that are treated as
deductible, co-insurance and out-of-pocket payments under the Parent's health
plan shall reduce the amount of any deductible, co-insurance or out-of-pocket
payments required to be paid for a similar period under the Alliance health
plan; provided, however, that the Sellers shall provide Alliance with a list of
all current and former employees participating in the Parent's health plan along
with a listing of each employee's deductible and co-insurance payments through
the Closing Date.

        (c) Effective as of the Closing, the Purchasers shall assume the
Parent's or Entities' obligations with respect to accrued sick pay, personal
holidays and vacation pay for Hired Employees, provided that the vacation pay
costs as of the Latest Balance Sheet Date have been accrued and reflected on the
Latest Balance Sheet.

        (d) Parent shall take such actions as are necessary to provide that the
Hired Employees are fully vested in their benefits under the Retirement Plan for
Employees of Parent and CT Sub (the "ASHS 401(k) Plan"). Parent shall also take
such actions as are



                                       38
   40

necessary to provide that the Hired Employees will be eligible to receive
distributions from the ASHS 401(k) Plan that will be eligible for rollover to
the Alliance "401(k)" plan. The Purchasers shall take such action as is

                                       42

        warranty (without regard to whether such representation or warranty is
        qualified by reference to materiality or "Material Adverse Effect") of
        the Sellers contained herein, in any Related Document, or in any
        certificate delivered by any Seller relating thereto delivered in
        connection herewith (or any facts or circumstances constituting any such
        untruth, inaccuracy or breach);

                (ii) the breach of any agreement or covenant of the Sellers
        contained in this Agreement or in any Related Document;

                (iii) any Liability of any Entity in any manner related to a

        Closing Date.

        (b) Subject to the further terms of this Article VIII, each of Alliance

   46
                    (iv) any Liability for Transfer Taxes to be borne by

        (c) Notwithstanding the foregoing the Purchasers shall not be entitled

hereof.

        (d) Absent fraud, the rights of the parties for indemnification relating

Agreement or arising in connection herewith.

8.2      ASSERTION OF CLAIMS.

         No claim shall be brought for a breach of a representation or warranty
under Section 8.1 hereof unless the Indemnified Persons, or any of them, at any
time prior to the applicable Survival Date, give the Indemnifying Persons (a)
written notice of the existence of any such claim, specifying the nature and
basis of such claim and the amount thereof, to the extent known or (b) written
notice pursuant to Section 8.3 of any Third Party Claim, the existence of which
might give rise to such a claim.  Upon the giving of such written notice as
aforesaid, the Indemnified Persons, or any of them, shall have the right to
commence legal proceedings prior to or subsequent to the Survival Date for the
enforcement of their rights under Section 8.1.

8.3      NOTICE AND DEFENSE OF THIRD PARTY CLAIMS.

         The obligations and liabilities of an Indemnifying Person with respect
to Losses resulting from the assertion of claim or Liability by third parties
other than in respect of Tax Claims (each, a "Third Party Claim") shall be
subject to the following terms and conditions:

        (a) The Indemnified Persons shall promptly give written notice to the
Indemnifying Persons of any Third Party Claim which might give rise to any Loss
by the Indemnified Persons, stating the nature and basis of such Third Party
Claim, and the amount thereof to the extent known; provided, however, that no
delay on the part of the Indemnified Persons in notifying any Indemnifying
Persons shall relieve the Indemnifying Persons from any liability or obligation
hereunder unless (and then solely to the extent) the Indemnifying Person thereby
is materially and irrevocably prejudiced by the delay. Such notice shall be
accompanied by copies of all relevant documentation with respect to such Third
Party Claim, including any summons, complaint or other pleading which may have
been served, any written demand or any other document or instrument.



                                       45
   47

        (b) If the Indemnifying Persons shall acknowledge in a writing delivered
to the Indemnified Persons that such Third Party Claim is properly subject to
their indemnification obligations hereunder, then the Indemnifying Persons shall
have the right to assume the defense of any Third Party Claim at their own
expense and by their own counsel, which counsel shall be reasonably satisfactory
to the Indemnified Persons; provided, however, that the Indemnifying Persons
shall not have the right to assume the defense of any Third Party Claim,
notwithstanding the giving of such written acknowledgment, if (i) the
Indemnified Persons shall have been advised by counsel that there are one or
more legal or equitable defenses available to them which are different from or
in addition to those available to the Indemnifying Persons, and, in the opinion
of the Indemnified Persons, counsel for the Indemnifying Persons could not
adequately represent the interests of the Indemnified Persons because such
interests could be in conflict with those of the Indemnifying Persons, or (ii)
the Indemnifying Persons shall not have assumed the defense of the Third Party
Claim in a timely fashion.

        (c) If the Indemnifying Persons shall assume the defense of a Third
Party Claim (under circumstances in which the proviso to the first sentence of
Section 8.3(b) is not applicable), the Indemnifying Persons shall not be
responsible for any legal or other defense costs subsequently incurred by the
Indemnified Persons in connection with the defense thereof. If the Indemnifying
Persons do not exercise their right to assume the defense of a Third Party Claim
by giving the written acknowledgment referred to in Section 8.3(b), or are
otherwise restricted from so assuming by the proviso to the first sentence of
Section 8.3(b), the Indemnifying Persons shall nevertheless be entitled to
participate in such defense with their own counsel and at their own expense. If
the defense of a Third Party Claim is assumed by the Indemnified Persons, the
Indemnified Persons shall not be entitled to settle such Third Party Claim
without the prior written consent of the Indemnifying Persons, which shall not
be unreasonably withheld.

        (d) If the Indemnifying Persons exercise their right to assume the
defense of a Third Party Claim, (i) the Indemnified Persons shall be entitled to
participate in such defense with their own counsel at their own expense and (ii)
the Indemnifying Persons shall not make any settlement of any claims without the
written consent of the Indemnified Persons, which shall not be unreasonably
withheld.

8.4      SURVIVAL OF REPRESENTATIONS AND WARRANTIES.

        (a) Subject to the further provisions of this Section 8.4, the
representations and warranties contained in this Agreement, the Related
Documents, or in any certificate or other writing delivered in connection with

however, that (i) the representations and warranties contained in Sections 3.1,
3.2, 3.3, 3.4, 3.21, 4.1, 4.2, 4.3, 4.4, 5.1, 5.2 and 5.3 (other than the

sentence of this Section 8.4(a)) of this Agreement shall survive indefinitely

of this Agreement shall survive the Closing Date until the expiration of any

   48

representations and warranties referenced in the foregoing clauses (i) and (ii),
being the "Excluded Representations and Warranties") for Third Party Claims
applicable to the matters covered thereby. The covenants and other agreements of
the parties contained in this Agreement and the Related Documents (including the
indemnity provided for in Section 8.1(a)(iii) of this Agreement) shall survive

obligations of the Sellers under Section 8.1(a)(iv) and (a)(v) shall survive the
Closing Date until the expiration of any applicable statute of limitations with
respect to the matters set forth therein. The obligations of Alliance and the
Purchasers under Section 8.1(b)(iv) shall survive the Closing Date until the
expiration of any applicable statute of limitations with respect to the matters
set forth therein.

or warranty contained herein shall terminate, if any, is referred to herein as

(without giving effect, in determining whether and to what extent

Document, individually or in the aggregate, in any material respect (except for
representations and warranties which are qualified by their terms by a reference
to materiality or "Material Adverse Effect" in which case, such representations
or warranties as so qualified shall have been breached in any respect),
covenant, obligation or agreement set forth in this Agreement or in any Related
Document and such breach shall not have been cured within 10 Business Days after
notice thereof is given by any Seller (except that no cure period shall be
provided for a breach which by its nature cannot be cured); or

        (d) either the Purchasers, Alliance or the Sellers, if the Closing shall
not have been consummated by September 15, 1998; or

        (e) either the Purchasers, Alliance or the Sellers, if any permanent
injunction or Order of a Governmental Entity preventing the Closing shall have
become final and nonappealable;

        (f) By either Parent or the Purchasers if, prior to the Closing Date,
(i) the Board of Directors of the Parent determines that a Third Party Proposal
for an Alternative Transaction constitutes a Superior Proposal, (ii) the Parent
promptly notifies the Purchasers of its determination in writing, which writing
shall set forth the terms and conditions of the Third Party Proposal and the
identity of the Person making the Third Party Proposal, (iii) ten days have
elapsed following receipt by the Purchasers of such written notice, (iv) during
such ten day period the Parent cooperates with the Purchasers with the intent of
enabling, but not obligating, the Purchasers to agree to a modification of the
terms and conditions of this Agreement so that the transactions contemplated
hereby may be effected, and (v) at the end of such ten day period, the Board of
Directors of the Parent continues to believe that such Third Party Proposal
constitutes a Superior Proposal and the Parent pays to the Purchasers the
amounts specified under Section 10.5(b) pursuant to the terms thereof. For
purposes of this Agreement, a "Superior Proposal" means any Third Party Proposal
to effect an Alternative Transaction; provided that (i) the Board of Directors
of the Parent determines in its good faith judgment (following the consultation
with, and the receipt of the advice of, the Parent's financial advisor) that
such Third Party Proposal is on terms that are more favorable to the Parent's
stockholders than the transactions contemplated by this Agreement (taking into
account all relevant factors, including the amount and form of consideration to
be received, the relative value of any non-cash consideration, and the timing
and certainty of closing) and (ii) the Board of Directors of the Parent
determines in its good faith judgment (based on the written advice of outside
counsel) that the failure to recommend or accept such Third Party Proposal would
violate the fiduciary duties of the Board of Directors of the Parent under
applicable Law;

provided, however, in each case, that none of the Sellers, Alliance nor the
Purchasers shall be entitled to terminate this Agreement if such party's breach
of this Agreement has prevented the satisfaction of a condition.  Any
termination pursuant to this Section 9.1 shall be effected by written notice
from the party or parties so terminating to the other parties hereto, which
notice shall specify the Section of this Agreement pursuant to which this
Agreement is being terminated.

9.2      EFFECT OF TERMINATION.

         In the event of the termination of this Agreement as provided in
Section 9.1, this Agreement shall be of no further force or effect, except for
Section 6.7, Section 10.5 and this Section 9.2, each of which shall survive the
termination of this Agreement; provided, however, that the Liability of any
party for any intentional, willful or knowing breach by



                                       49
   51

such party of the representations, warranties, covenants, obligations or
agreements of such party set forth in this Agreement occurring prior to the
termination of this Agreement shall survive the termination of this Agreement
and, in addition, in the event of any action for breach of contract in the event
of a termination of this Agreement, the prevailing party shall be reimbursed by
the other party to the action for reasonable attorneys' fees and expenses
relating to such action.

enforceability of such provision in any other jurisdiction.
