Item 5.  Other Events

         On July 31, 1997, Sterling House Corporation (the "Company") announced
that it had entered into an Agreement and Plan of Merger, dated as of July 30,
1997 (the "Merger Agreement"), with Alternative Living Services, Inc., a
Delaware corporation ("ALS"), and Tango Merger Corporation, a Kansas
corporation and a wholly owned subsidiary of ALS ("Merger Sub"), which provides
for the merger (the "Merger") of Merger Sub with and into the Company with the
Company continuing as the surviving corporation. Pursuant to the Merger
Agreement, at the effective time of the Merger (the "Effective Time"), each
share of Common Stock, no par value per share, of the Company ("Company Common
Stock"), outstanding immediately prior to the Effective Time will be converted
into the right to receive 1.1 shares of common stock, par value $0.01 per
share, of ALS ("ALS Common Stock"). The Merger is subject to certain
conditions, including required regulatory and shareholder approvals.

         Concurrently with the execution of the Merger Agreement, ALS and the
Company entered into a Cross Option Agreement (the "Cross Option Agreement")
whereby (i) ALS granted to the Company an option to purchase 2,586,303 shares
of ALS Common Stock at $21.625 per share, exercisable only if the Merger
Agreement becomes terminable or is terminated under circumstances which could
entitle the Company to termination fees under the Merger Agreement, and (ii)
the Company granted to ALS an option to purchase 1,003,344 shares of Company
Common Stock at $18.25 per share, exercisable only if the Merger Agreement
becomes terminable or is terminated under circumstances which would entitle ALS
to termination fees under the Merger Agreement.

         In connection with the execution and delivery of the Merger Agreement,
(i) Mr. Timothy J. Buchanan, Chairman of the Board and Chief Executive Officer
of the Company, entered into an employment agreement with ALS pursuant to which
Mr. Buchanan will become the President of ALS at the Effective Time of the
Merger, (ii) Mr. Steven L. Vick, President of the Company, entered into an
employment agreement with ALS and the Company pursuant to which Mr. Vick will
remain as President of the Company following the Merger and will thereafter
become the Chief Operating Officer of ALS. Both employment agreements become
effective only upon consummation of the Merger.

         On July 30, 1997, certain affiliates of the Company (each, a "Company
Shareholder"), who collectively own approximately 46% of the outstanding shares
of Company Common Stock entered into Stockholder Voting Agreements (each, a
"Voting Agreement") with ALS pursuant to which each Company Shareholder
appointed ALS such Company Shareholder's lawful proxy and attorney-in-fact to
vote such Company Shareholder's Company Common Stock in favor of the approval
of the Merger Agreement and the Merger and against any
<PAGE>   3



"Third Party Transaction" (as such term is defined in the Merger Agreement). On
such date, the Company entered into Voting Agreements with certain affiliates of
ALS (each, an "ALS Stockholder"), who collectively own approximately 26% of the
outstanding shares of ALS Common Stock, pursuant to which each ALS Stockholder
appointed the Company such ALS Stockholder's lawful proxy and attorney-in-fact
to vote such ALS Stockholder's ALS Common Stock in favor of the approval of the
Merger Agreement and the Merger and against any Third Party Transaction.

         Copies of (i) the Merger Agreement including the exhibits thereto,
(ii) the Cross Option Agreement, (iii) Mr. Buchanan's Employment Agreement,
(iv) Mr. Vick's Employment Agreement, (v) the form of Voting Agreement between
the Company and the ALS Stockholders and (vi) the form of Voting Agreement
between ALS and the Company Shareholders, are filed as exhibits hereto. The
foregoing descriptions are qualified in their entirety by reference to such
exhibits.

         A copy of the press release issued by the Company on July 31, 1997
with respect to the Merger is attached hereto as Exhibit 99.1 and is
incorporated herein by reference.

         On July 30, 1997, the Company entered into Amendment No. 1 to the
Rights Agreement (the "Amendment"), between the Company and ChaseMellon
Shareholder Services, L.L.C., a New Jersey limited liability company (the
"Rights Agent"), which Amendment amended the Rights Agreement, dated June 25,
1997, between the Company and the Rights Agent to clarify the definition of
"Acquiring Person."

                          AGREEMENT AND PLAN OF MERGER


         AGREEMENT AND PLAN OF MERGER ("Agreement") dated as of July 30, 1997
among ALTERNATIVE LIVING SERVICES, INC., a Delaware corporation (referred to
herein as "Tango"), TANGO MERGER CORPORATION, a Kansas corporation and a wholly
owned subsidiary of Tango (referred to herein as "Merger Sub"), and STERLING
HOUSE CORPORATION, a Kansas corporation (referred to herein as "Twister").

         WHEREAS, the Boards of Directors of Tango, Merger Sub and Twister have
approved, and deem advisable, consistent with their respective long-term
business strategies and in the best interests of their respective stockholders,
to consummate the merger of Merger Sub with and into Twister (the "Merger")
upon the terms and conditions set forth herein and in accordance with the
Kansas General Corporation Code (the "KGCC") (Twister, following the
effectiveness of the Merger, being hereinafter sometimes referred to as the
"Surviving Corporation");

         WHEREAS, concurrently with the execution and delivery of this
Agreement, as a condition of Tango's and Twister's willingness to enter into
this Agreement, Tango and Twister are entering into a Stock Option Agreement
dated the date hereof and attached as Exhibit D hereto (the "Cross Option
Agreement") pursuant to which (A) Tango is granting to Twister an option to
purchase shares of the common stock, par value $0.01 per share, of Tango (the
"Tango Common Stock") and (B) Twister is granting to Tango an option to
purchase shares of the common stock, no par value per share, of Twister (the
"Twister Common Stock");

         WHEREAS, Tango and Twister desire to make certain representations,
warranties and agreements in connection with the Merger and also to prescribe
various conditions to the Merger;

         WHEREAS, for Federal income tax purposes, it is intended that the
Merger shall qualify as a reorganization within the meaning of Section 368(a)
of the Internal Revenue Code of 1986, as amended (the "Code"); and

         WHEREAS, for accounting purposes it is intended that the Merger shall
be accounted for as a "pooling of interests" pursuant to Opinion No. 16 of the
Accounting Principles Board.

         NOW, THEREFORE, in consideration of the mutual representations,
warranties, covenants, agreements and conditions contained herein, and in order
to set forth the terms and conditions of the Merger and the method of carrying
the same into effect, the parties hereby agree as follows:

hereinafter set forth, and in accordance with KGCC, at the Effective Time (as
defined in Section 1.3), Merger Sub shall be merged with and into Twister.  As
a result of the Merger, the separate corporate existence of Merger Sub shall

Sterling House Corporation.

         1.2     Closing.  Subject to the terms and conditions of this
Agreement, the closing of the Merger (the "Closing") shall take place at the
offices of Tango at 450 N. Sunnyslope Road, Suite 300, Brookfield, Wisconsin

date as may be agreed to in writing by the parties hereto.  The date on which
the Closing occurs is hereinafter referred to as the "Closing Date."

         1.3     Effective Time.  If all the conditions to the Merger set forth
in Article VI shall have been satisfied or if permissible, waived in accordance
herewith and this Agreement shall not have been terminated as provided in
Article VII, the parties hereto shall cause the Merger to be consummated by
filing a certificate of merger meeting the requirements of the KGCC
("Certificate of Merger") with the Secretary of State of Kansas in such form as
required by, and executed in accordance with such requirements of, the KGCC on
the Closing Date.  The Merger shall become effective at the time of filing of
the Certificate of Merger with the Secretary of State of the State of Kansas in
accordance with the KGCC or at such other time which the parties hereto shall
have agreed upon and designated in such filing as the effective time of the
Merger (the "Effective Time").

         1.4     Effect of Merger.  At the Effective Time, the effect of the
Merger shall be as provided in the applicable provisions of the KGCC.  Without

Time, except as otherwise provided herein, the separate existence of Merger Sub
will cease and the Surviving Corporation shall succeed, without other transfer,
to all the rights, privileges, powers, franchises and property of Merger Sub
and shall be subject to all the debts, duties and liabilities of Merger Sub in
the same manner as if the Surviving Corporation had itself incurred them.

         1.5     Articles of Incorporation and Bylaws.  At the Effective Time,
the Articles of Incorporation and the Bylaws attached as Exhibit A shall be the
Articles of Incorporation and Bylaws of the Surviving Corporation.

         1.6     Directors and Officers.  The persons set forth on Schedule

         If, prior to the Effective Time, Tango or Twister should split or
         combine their respective Common Stock, or pay a stock dividend or
         other stock distribution in their respective Common Stock, or
         otherwise change their respective Common Stock into any other
         securities, or make any other dividend or distribution on their
         respective Common Stock, then the Exchange Ratio will be appropriately
         adjusted to reflect such split, combination, dividend or other
         distribution or change.  The Exchange Ratio shall be rounded, in each
         case, to the nearest ten-thousandth of a share.

                 (b)      All of the shares of the Twister Common Stock
         (together with Rights) to be converted into Tango Common Stock
         pursuant to Section 2.1(a) (the "Twister Shares") shall cease to be
         outstanding, shall be cancelled and retired and shall cease to exist,
         and each holder of a certificate representing any such shares shall
         thereafter represent the right to receive for each of the shares, upon
         the surrender of such certificate in accordance with Section 2.2(b),
         the amount of the Tango Common Stock specified above (the "Share
         Consideration") and cash in lieu of fractional Tango Common Stock as
         contemplated by Section 2.4.  The holders of such certificates
         previously evidencing such shares of Twister Common Stock immediately
         prior to the Effective Time shall cease to have any rights with
         respect to such shares of Twister Common Stock except as otherwise
         provided herein or by law.

                 (c)      The issued and outstanding shares of the common
         stock, $.01 par value, of Merger Sub (the "Merger Sub Common Stock")
         shall be converted into one hundred (100) shares of fully paid and
         nonassessable shares of common stock, $.01 par value, of the Surviving
         Corporation ("Surviving Corporation Common Stock").

                 (d)      All shares of Twister Common Stock which are owned as
         Treasury Shares  and each share of Twister Common Stock owned by Tango
         or any direct or indirect wholly owned subsidiary of Tango or of
         Twister immediately prior to the Effective Time shall be cancelled and
         retired and cease to exist, without any conversion thereof or payment
         with respect thereto.

                 (e)      Each outstanding option to purchase Twister Common
         Stock (each a, "Twister Stock Option") and each outstanding 6.75%
         Convertible Subordinated Debenture due 2006 of Twister (the "Twister
         Debentures") shall be assumed by Tango in the manner provided in
         Section 5.7.

         2.2     Payment for Shares in the Merger.

                 (a)      At the Effective Time, Tango shall deposit, or shall
cause to be deposited, with a bank or trust company selected by Tango and
reasonably acceptable to Twister as exchange agent for the Twister Shares in
accordance with this Article II (the "Exchange Agent"), for the benefit of
those persons who immediately prior to the Effective Time were the holders of
Twister Shares, a sufficient number of certificates representing shares of
Tango Common Stock required to effect the delivery of the aggregate Share
Consideration required to be issued pursuant to Section 2.1 (the certificates
representing Tango Common Stock comprising such aggregate Share Consideration,
together with any dividends or distributions with respect thereto, being
hereinafter referred to as the "Exchange Fund").  The Exchange Agent shall,
pursuant to irrevocable instructions from Tango, deliver the shares of Tango
Common Stock contemplated to be issued pursuant to Section 2.1 and effect the
sales provided for in Section 2.4 out of the Exchange Fund.  The Exchange Fund
shall not be used for any other purpose.

                 (b)      As soon as reasonably practicable after the Effective
Time, Tango shall cause the Exchange Agent to send to each holder of record of
a certificate or certificates which immediately prior to the Effective Time
evidenced outstanding shares of Twister Common Stock (the "Certificates"), (A)
a letter of transmittal (which shall specify that delivery shall be effected,
and risk of loss and title to the Certificates shall pass, only upon proper
delivery of the Certificates to the Exchange Agent and shall be in such form
and have such other provisions as Tango may reasonably specify) and (B)
instructions for use in effecting the surrender of the Certificates in exchange
for certificates evidencing the Share Consideration and cash in lieu of
fractional shares, if any.  Upon the surrender for exchange of a Certificate,
together with such letter of transmittal duly completed and properly executed
in accordance with instructions thereto and such other customary documents as
may be reasonably required pursuant to such instructions, the holder of such
Certificate shall be entitled to receive in exchange therefor (X) certificates
evidencing the Share Consideration to which such holder is entitled hereunder,
(Y) cash in lieu of fractional shares of Tango Common Stock to which such
holder is entitled pursuant to Section 2.4 herein and (Z) any dividends or
other distribution to which such holder is entitled pursuant to Section 2.2(c)
herein (the Share Consideration, the dividends, distributions and cash
described in clauses (X), (Y) and (Z) being collectively referred to as the
"Merger Consideration"), and the surrendered Certificate shall forthwith be
cancelled.  Until so







                                      -4-
<PAGE>   10

surrendered and exchanged, the Certificates shall represent solely the right to
receive the Merger Consideration, subject to any required withholding of taxes.
If Share Consideration for any Twister Shares is to be issued to a person other
than the person in whose name the Certificates for such shares surrendered are
registered, it shall be a condition of the exchange that the person requesting
such exchange shall pay to the Exchange Agent any transfer or other taxes
required by reason of the delivery of such Share Consideration to a person
other than the registered owner of the Certificates surrendered or shall
establish to the satisfaction of the Exchange Agent that such tax has been paid
or is not applicable.  Unless prohibited by law, former stockholders of record
of Twister shall be entitled to vote, after the Effective Time, at any meeting
of Tango stockholders, the number of whole shares of Tango Common Stock into
which their respective Twister Shares are converted, regardless of whether such
holders have exchanged their Certificates in accordance with this Section 2.2.

                 (c)      No dividends or other distributions with respect to
Tango Common Stock with a record date after the Effective Time shall be paid to
the holders of any unsurrendered Certificate with respect to the shares of
Tango Common Stock represented thereby, and no other part of the Merger
Consideration shall be paid to any such holder, until the surrender of such
Certificate in accordance with this Section 2.2.  Subject to the effect of
applicable laws, following surrender of any such Certificate, there shall be
paid by Tango or the Exchange Agent to the holder of the certificates
evidencing whole shares of Tango Common Stock issued in exchange therefor, in
addition to the Share Consideration to be issued in exchange therefor, without
interest, (i) at the time of such surrender, the amount of any cash payable in
lieu of a fractional share of Tango Common Stock to which such holder is
entitled pursuant to Section 2.4 and the amount of dividends or other
distributions, with a record date after the Effective Time theretofore paid
with respect to such Share Consideration, and (ii) at the appropriate payment
date, the amount of dividends or other distributions, with a record date after
the Effective Time but prior to such surrender and with a payment date
subsequent to such surrender, payable with respect to such Share Consideration.

                 (d)      In the event any Certificates shall have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if required by
Tango, the posting by such person of a bond in such amount, form and with such
surety as Tango may reasonably direct as indemnity against any claim that may
be made against it with respect to such Certificate, the Exchange Agent will
issue in exchange for such lost, stolen or destroyed Certificate the number of
shares of the Tango Common Stock and cash in lieu of fractional shares
deliverable (and unpaid dividends and distributions) in respect thereof
pursuant to this Agreement.

                 (e)      Tango, as the sole stockholder of Merger Sub, shall,
upon surrender to the Surviving Corporation of certificates representing the
Merger Sub Common Stock, receive a certificate representing the number of
shares of the Surviving Corporation Common Stock into which such Merger Sub
Common Stock shall have been converted pursuant to Section 2.1.







                                      -5-
<PAGE>   11

                 (f)      Certificates surrendered for exchange by any person
constituting a Pooling Affiliate of Twister (as defined in Section 5.13) shall
not be exchanged for certificates representing Tango Common Stock until Tango
has received a written agreement from such person as provided in Section 5.13.

         2.3     Exchange Agent.  Tango shall cause the Exchange Agent to
agree, among other things, that (i) the Exchange Agent shall maintain the
Exchange Fund as a separate fund to be held for the benefit of the holders of
the Twister Shares, which shall be promptly applied by the Exchange Agent to
making the payments provided for in Section 2.2, (ii) any portion of the
Exchange Fund that has not been paid to holders of the Twister Shares pursuant
to Section 2.2 prior to that date which is one year from the Effective Time
shall be delivered to Tango, and any holders of Twister Shares who shall not
have theretofore complied with Section 2.2 shall thereafter look only to Tango
for the Merger Consideration; (iii) the Exchange Fund shall not be used for any
purpose that is not provided for herein, and (iv) all expenses of the Exchange
Agent shall be paid directly by Tango.  Promptly following the date which is
one year from the Effective Time, the Exchange Agent shall return to Tango all
cash, securities and any other instruments in its possession relating to the
transactions described in this Agreement, and the Exchange Agent's duties shall
terminate.  Thereafter, each holder of Certificates may surrender such
Certificates to Tango and (subject to applicable abandoned property, escheat
and similar laws) receive in exchange therefor the Merger Consideration payable
with respect thereto, without interest, but shall have no greater rights
against Tango than may be accorded to general creditors of Tango under the
Delaware General Corporation Law (the "DGCL").  The Exchange Agent shall not be
entitled to vote or exercise any rights of ownership with respect to the Tango
Common Stock held by it from time to time hereunder.  Neither Tango nor the
Surviving Corporation shall be liable to any holder of shares of Twister Common
Stock for any Merger Consideration from the Exchange Fund delivered to a public
official pursuant to any applicable abandoned property, escheat or similar law.

         2.4     Fractional Shares.

                 (a)      No certificates or scrip evidencing fractional shares
of Tango Common Stock shall be issued in the Merger.  In lieu of any such
fractional shares, each holder of Twister Shares who would otherwise have been
entitled to a fractional share of Tango Common Stock upon surrender of
Certificates for exchange pursuant to this Article II will be paid an amount in
cash (without interest), rounded to the nearest cent, equal to such holder's
proportionate interest in the Fractional Securities Fund (as defined below).
As promptly as practicable following the Effective Time, the Exchange Agent
shall determine the excess of (i) the number of full shares of the Tango Common
Stock delivered to the Exchange Agent by Tango pursuant to Section 2.2(b) over
(ii) the aggregate number of full shares of the Tango Common Stock to be
distributed to holders of Twister Shares pursuant to Section 2.2(b) (such
excess being herein called the "Excess Shares"), and the Exchange Agent, as
agent for the holders of Twister Shares, shall sell the Excess Shares at then
prevailing prices on the American Stock Exchange ("AMEX"), all in the manner
provided in this Section 2.4(a).  The sale of the Excess Shares by the Exchange
Agent shall be executed on the AMEX through one or more







                                      -6-
<PAGE>   12

member firms of the AMEX and shall be executed in round lots to the extent
practicable.  Tango shall pay all commissions, transfer taxes and other
out-of-pocket transaction costs, including the expenses and compensation of the
Exchange Agent, incurred in connection with such sale of Excess Shares.  Until
the net proceeds of such sale or sales have been distributed to the holders of
Twister Shares, the Exchange Agent will hold such proceeds in trust for such
holders of Twister Shares (the "Fractional Securities Fund").

                 (b)      In lieu of establishing the Fractional Securities
Fund pursuant to Section 2.4(a), the Exchange Agent may, at the direction of
Tango and Twister prior to the Effective Time, pay any cash amounts due the
former stockholders of Twister directly from cash made available to the
Exchange Agent by Tango for such purpose, in which event, each holder of
Twister Shares who would otherwise have been entitled to receive a fraction of
a share of Tango Common Stock (after taking into account all Certificates
delivered by such holder) shall receive, in lieu of thereof, cash (without
interest) in an amount equal to such fractional part of a share of Tango Common
Stock multiplied by the closing price of a share of Tango Common Stock on the
business day immediately preceding the Closing Date as reported on the AMEX as
reported by The Wall Street Journal.

                 (c)      As soon as practicable after the determination of the
amount of cash to be paid to holders of Twister Shares in lieu of any
fractional interests, the Exchange Agent shall make available in accordance
with this Agreement such amounts to such holders.

         2.5     Transfer of Shares After the Effective Time.  No transfers of
Twister Shares shall be made on the stock transfer books of Twister after the
Effective Time.

         2.6     Further Assurances.  If, at any time after the Effective Time,
the Surviving Corporation shall consider or be advised that any further deeds,
assignments or assurances in law or any other acts are necessary, desirable or
proper (a) to vest, perfect or confirm, of record or otherwise, in the
Surviving Corporation, the title to any property or right of Twister or Merger
Sub acquired or to be acquired by reason of, or as a result of, the Merger, or
(b) otherwise to carry out the purposes of this Agreement, Twister and Merger
Sub agree that the Surviving Corporation and its proper officers and directors
shall and will execute and deliver all such deeds, assignments and assurances
in law and do all acts necessary, desirable or proper to vest, perfect or
confirm title to such property or right in the Surviving Corporation and
otherwise to carry out the purposes of this Agreement, and that the proper
officers and directors of the Surviving Corporation are fully authorized in the
name of Twister and Merger Sub or otherwise to take any and all such action.

                                  ARTICLE III
             REPRESENTATIONS AND WARRANTIES OF TANGO AND MERGER SUB

         Tango and Merger Sub, jointly and severally, represent and warrant to
Twister that, except as set forth in the Disclosure Schedule delivered prior
hereto (the "Tango Disclosure Schedule"), which shall identify exceptions by
specific Section references:

         3.1     Corporate Organization.  Each of Tango, Merger Sub and Tango's
Subsidiaries (the "Tango Subsidiaries") has been duly organized and is validly
existing and in good standing under the laws of the jurisdiction of its
organization, has all requisite power and authority to own, operate and lease
its properties and to carry on its business as it is now being conducted, and
is qualified or licensed to do business and is in good standing in each
jurisdiction in which the nature of the business conducted by it or the
ownership or leasing of its properties makes such qualification necessary,
other than where the failure to be so qualified or licensed, individually or in
the aggregate, would not have a Material Adverse Effect on Tango.  The term
"Material Adverse Effect on Tango" as used in this Agreement shall mean any
change or effect that, individually or when taken together with all such other
changes or effects, would be materially adverse to the financial condition,
results of operations, properties or business of Tango and the Tango
Subsidiaries taken as a whole at the time of such change or effect.  True and
complete copies of the Amended and Restated Certificate of Incorporation
("Tango Restated Certificate of Incorporation") and the Bylaws of Tango (the
"Tango Bylaws") have heretofore been delivered to Twister, and such Amended and
Restated Certificate of Incorporation and Bylaws are in full force and effect.
True and complete copies of the Articles of Incorporation and Bylaws of Merger
Sub have heretofore been delivered to Twister, and such Articles of
Incorporation and Bylaws are in full force and effect.  Section 3.1 of the
Tango Disclosure Schedule contains a complete and accurate list of all of the
Tango Subsidiaries and Section 3.1 of the Tango Disclosure Schedule sets forth
Tango's percentage ownership in each such Subsidiary.  Neither Tango nor any
Tango Subsidiary is in violation of any provision of its articles or
certificate of incorporation or bylaws (each as may have been amended or
restated) or other organizational documents, as the case may be.  Merger Sub
was formed solely for the purpose of engaging in the transactions contemplated
by this Agreement.  As of the date hereof and the Effective Time, except for
obligations or liabilities incurred in connection with its incorporation or
organization and the transactions contemplated by this Agreement and except for
this Agreement and any other agreements or arrangements contemplated by this
Agreement, Merger Sub has not and will not have incurred, directly or
indirectly, through any Subsidiary or affiliate, any liabilities or obligations
or engaged in any business activities of any type or kind whatsoever or entered
into any agreements or arrangements with any person.

         3.2     Capitalization.  As of the date of this Agreement, the
authorized capital stock of Tango consists of (i) 30,000,000 shares of Tango
Common Stock and (ii) 5,000,000 shares of preferred stock, $.01 par value
("Tango Preferred Stock").  As of the date of this Agreement, (i) 12,996,498
shares of Tango Common Stock are issued and outstanding, all of which were duly
authorized, validly issued, fully paid and nonassessable and not subject to
preemptive rights created by statute, the Tango Restated Certificate of
Incorporation or the Tango Bylaws or any







                                      -8-
<PAGE>   14

agreement to which Tango is a party or by which Tango is bound and (ii) 11,639
shares of Tango Common Stock were held in the treasury of Tango.  As of the
date hereof, no shares of Tango Preferred Stock are issued and outstanding.  As
of the date of this Agreement, 799,695 shares of Tango Common Stock are
reserved for future issuance pursuant to employee stock options granted
pursuant to Tango's Amended and Restated 1995 Incentive Plan (the "1995 Plan")
and certain other option arrangements (any stock option so issued being a
"stock option").  In addition to the foregoing, 2,469,136 shares of Tango
Common Stock are reserved for issuance upon conversion of Tango's $50,000,000
principal amount of aggregate outstanding 7.0% Convertible Subordinated
Debentures Due 2004.  As of the date of this Agreement, the authorized capital
of Merger Sub consists of 1,000 shares of common stock, $.01 par value per
share, of which 100 shares are issued and outstanding and were duly authorized,
validly issued, fully paid and nonassessable and not subject to preemptive
rights created by statute, Merger Sub's Articles of Incorporation or Bylaws or
any agreement to which Merger Sub is a party or by which Merger Sub is bound.
Tango has heretofore delivered to Twister a correct and complete copy of the
1995 Plan and a schedule identifying all outstanding stock options issued,
including those issued under the 1995 Plan.  The schedule of outstanding
options sets forth for each stock option holder (i) such holder's name, (ii)
the date of grant of stock options to such holder, (iii) the number of shares
of Tango Common Stock into which each such grant is exercisable, (iv) the
exercise price per share of Tango Common Stock with respect to each such grant,
and (v) the periods during which such stock options or portions thereof are
exercisable by such holder.  Except as set forth in this Section 3.2 or in
Section 3.2 of the Tango Disclosure Schedule, there are no options, warrants or
other rights (including registration rights), agreements, arrangements or
commitments of any character to which Tango or any Tango Subsidiary is a party
relating to the issued or unissued capital stock of, or other equity interests
in, Tango or any Tango Subsidiary or obligating Tango or any Tango Subsidiary
to grant, issue or sell any shares of capital stock of, or other equity
interests in, Tango or any Tango Subsidiary, by sale, lease, license or
otherwise.  All shares of Tango Common Stock subject to issuance as aforesaid,
upon issuance on the terms and conditions specified in the instruments pursuant
to which they are issuable, will be duly authorized, validly issued, fully paid
and nonassessable and will not have been issued in violation of or subject to
any preemptive rights created by statute, the Tango Restated Certificate of
Incorporation or Tango Bylaws or any agreement to which Tango is a party or by
which Tango is bound.  Except as set forth in this Section 3.2 or in the Tango
Current Reports (hereinafter defined), there are no outstanding contractual
obligations, contingent or otherwise, of Tango or any Tango Subsidiary to (x)
repurchase, redeem or otherwise acquire any shares of Tango Common Stock or any
capital stock of, or other equity interests in, any Tango Subsidiary, or (y)
except for guarantees of obligations of, or loans or capital contribution
commitments to, Tango Subsidiaries entered into in the ordinary course of
business, provide funds to, or make any investment in (in the form of a loan,
capital contribution or otherwise), or provide any guarantee with respect to
the obligations of, any Tango Subsidiary or any other person.  Each outstanding
share of capital stock of, or other equity interests in, each Tango Subsidiary
is duly authorized, validly issued, fully paid and nonassessable and, except as
set forth in Section 3.2 of the Tango Disclosure Schedule, each such share or
other equity interest owned by Tango or another Tango Subsidiary is owned free
and clear of all security interests, liens, claims, pledges, options, rights of
first







                                      -9-
<PAGE>   15

refusal, agreements, limitations on Tango's or such other Tango Subsidiary's
voting rights, charges and other encumbrances of any nature whatsoever.

         3.3     Options or Other Rights.  Except as disclosed in Section 3.2
or in the Tango SEC Filings (hereinafter defined), there is no outstanding
right, subscription, warrant, call, unsatisfied preemptive right, option or
other agreement or arrangement of any kind to purchase or otherwise to receive
from Tango or any Tango Subsidiary any of the outstanding authorized but
unissued, unauthorized or treasury shares of the capital stock or any other
security of Tango or any Tango Subsidiary, and there is no outstanding security
of any kind convertible into or exchangeable for such capital stock.  Except as
set forth in Section 3.3 of the Tango Disclosure Schedule, there are no
agreements or understandings among Tango or any Tango Subsidiary on the one
hand and any other person on the other hand concerning the registration of any
security of Tango or a Tango Subsidiary under the Securities Act.  Except as
set forth on Section 3.3 of the Tango Disclosure Schedule, no options granted
under the 1995 Plan have provisions which accelerate the vesting or right to
exercise such options upon the occurrence of certain events, including, but not
limited to, the consummation of the Merger.

         3.4     Authority Relative to this Agreement.

                 (a) Tango has all requisite corporate power and authority to

and registered or exempt from registration under applicable Blue Sky Laws and

         3.6     No Violation.  The execution and delivery of this Agreement by
each of Tango and Merger Sub and of the Cross Option Agreement by Tango do not,

described in clause (iv) that would not have a Material Adverse Effect on Tango
and except where the failure to obtain such consents, approvals, authorizations
or permits, or to make such filings or notifications would not, either
individually or in the aggregate, prevent Tango or Merger Sub from performing
any of their respective obligations under this Agreement or prevent Tango from
performing any of its obligations under the Cross Option Agreement and would
not have a Material Adverse Effect on Tango.  Neither Tango nor any of its
affiliates or associates (as each such term is defined in Section 17-1297 of
the KGCC) is, prior to the date hereof, an "interested shareholder" (as such
term is defined in Section 17-12,100 of the KGCC) of Twister.

         3.7     Compliance with Laws.

                 (a)      As of the date of this Agreement, each of Tango and
the Tango Subsidiaries holds all licenses, franchises, grants, permits,
easements, variances, exemptions, consents, certificates, identification
numbers, approvals, orders and other authorizations (collectively, "Tango
Permits") necessary to own, lease and operate its properties and to carry on
its business as it is now being conducted, are certified as providers under all
applicable Medicare and Medicaid programs to the extent required to be so
certified, and are in compliance with all Tango Permits and all Laws governing
their respective businesses, including, without limitation, the requirements,
guidelines, rules and regulations of Medicare, Medicaid, state approved
Medicaid waiver programs and other third-party reimbursement programs, except
where the failure to hold such Tango Permits or to so comply, individually or
in the aggregate, would not have a Material Adverse Effect on Tango.

                 (b)      To Tango's knowledge, all health care personnel
employed by Tango or any Tango Subsidiary are properly licensed to the extent
required to perform the duties of their employment in each jurisdiction where
such duties are performed, except where the failure to be so licensed,
individually or in the aggregate, would not have a Material Adverse Effect on
Tango.

                 (c)      Except as set forth in Section 3.7 of the Tango
Disclosure Schedule, no action or proceeding is pending or, to Tango's
knowledge, threatened that may result in the suspension, revocation or
termination of any Tango Permit, the issuance of any cease-and-desist order, or
the imposition of any administrative or judicial sanction, and neither Tango
nor any Tango Subsidiary has received any notice from any governmental
authority in respect of the suspension, revocation or termination of any Tango
Permit, or any notice of any intention to conduct any investigation or
institute any proceeding, in any such case where such suspension,







                                      -12-
<PAGE>   18

revocation, termination, order, sanction, investigation or proceeding would
result, individually or in the aggregate, in a Material Adverse Effect on
Tango.

                 (d)      Neither Tango nor any Tango Subsidiary has received
notice that Medicare, Medicaid, state approved Medicaid waiver programs or any
other third-party reimbursement program has any claims for disallowance of
costs against any of them which could result in offsets against future
reimbursement or recovery of prior payments, which offsets or recoveries,
individually or in the aggregate, would have a Material Adverse Effect on
Tango.

         3.8     Litigation.  As of the date of this Agreement, except as may
be disclosed in the Tango 10-K (as defined below), reports filed on Forms 10-Q
or 8-K or proxy statements filed on Schedule 14A for periods subsequent to the
period covered by such Tango 10-K, in each case filed prior to the date hereof
(such reports and filings, collectively, the "Tango Current Reports"), there is
no claim, litigation, suit, arbitration, mediation, action, proceeding, unfair
labor practice complaint or grievance pending or, to Tango's knowledge,
investigation of any kind, at law or in equity (including actions or
proceedings seeking injunctive relief), pending or, to Tango's knowledge,
threatened in writing against Tango or any Tango Subsidiary or with respect to
any property or asset of any of them, except for claims, litigations, suits,
arbitrations, mediations, actions, proceedings, complaints, grievances or
investigations which, individually or in the aggregate, would not have a
Material Adverse Effect on Tango.  Neither Tango nor any Tango Subsidiary nor
any property or asset of any of them is subject to any continuing order,
judgment, settlement agreement, injunction, consent decree or other similar
written agreement with or, to Tango's knowledge, continuing investigation by,
any Governmental Entity, or any judgment, order, writ, injunction, consent
decree or award of any Governmental Entity or arbitrator, including, without
limitation, cease-and-desist or other orders, except for such matters which
would not reasonably be expected to have a Material Adverse Effect on Tango.

         3.9     Financial Statements and Reports.  Tango has made available to
Twister true and complete copies of (a) its Annual Report on Form 10-K for the
year ended December 31, 1996 (the "Tango 10-K") as filed with the Securities
and Exchange Commission (the "Commission"), (b) all registration statements
filed by Tango and declared effective under the Securities Act (other than
registration statements on Form S-8), and (c) all other reports, statements and
registration statements (including Quarterly Reports on Form 10-Q and Current
Reports on Form 8-K but excluding preliminary material and reports pursuant to
Sections 13(d) or 13(g) of the Exchange Act) filed by it with the Commission.
The reports, statements and registration statements referred to in the
immediately preceding sentence (including, without limitation, any financial
statements or schedules or other information, included or incorporated by
reference therein) are referred to in this Agreement as the "Tango SEC
Filings." As of the respective times such documents were filed or, as
applicable, were effective, the Tango SEC Filings complied in all material
respects with the requirements of the Securities Act or the Exchange Act, as
the case may be, and the rules and regulations promulgated thereunder, except
for such noncompliance which, individually or in the aggregate, would not have
a Material Adverse Effect on Tango, and did not contain any untrue statement of
a material fact or omit to state any material fact required to be stated
therein or necessary to make the statements therein, in light







                                      -13-
<PAGE>   19

of the circumstances under which they were made, not misleading.  The financial
statements of Tango included in the Tango SEC Filings comply as to form in all
material respects with applicable accounting requirements and with the
published rules and regulations of the Commission with respect thereto, were
prepared in accordance with generally accepted accounting principles (as in
effect from time to time) applied on a consistent basis during the periods
involved (except as may be indicated therein or in the notes thereto or, in the
case of the unaudited interim financial statements, as permitted by Form 10-Q
of the Commission) and present fairly the consolidated financial position,
consolidated results of operations and consolidated cash flows of Tango and the
Tango Subsidiaries as of the dates and for the periods indicated, except (i) in
the case of unaudited interim consolidated financial statements, to normal
recurring year-end adjustments and any other adjustments described therein and
(ii) any pro forma financial information contained therein is not necessarily
indicative of the consolidated financial position of Tango and the Tango
Subsidiaries as of the respective dates thereof and the consolidated results of
operations and cash flows for the periods indicated.  No Tango Subsidiary is
required to file any form, report or other document with the Commission.

         3.10    Absence of Certain Changes or Events.  Other than as disclosed
in the Tango Current Reports or otherwise disclosed in this Agreement, since
December 31, 1996 and through the date hereof, the business of Tango and of
each of the Tango Subsidiaries has been conducted in the ordinary course, and
there has not been (i) any Material Adverse Effect on Tango; (ii) any material
indebtedness incurred by Tango or any Tango Subsidiary for money borrowed,
except under credit facilities disclosed in the Tango Current Reports, if any;
(iii) any material transaction or commitment, except in the ordinary course of
business or as contemplated by this Agreement, entered into by Tango or any of
the Tango Subsidiaries; (iv) any damage, destruction or loss, whether covered
by insurance or not, which, individually or in the aggregate, would have a
Material Adverse Effect on Tango; (v) any material change by Tango in
accounting principles or methods except insofar as may be required by a change
in generally accepted accounting principles; (vi) any declaration, setting
aside or payment of any dividend (whether in cash, securities or property) with
respect to the Tango Common Stock; or (vii) any material agreement to acquire
any assets or stock or other interests of any third-party; (viii) any increase
in the compensation payable or to become payable by Tango or any Tango
Subsidiary to any employees, officers, directors, or consultants or in any
bonus, insurance, welfare, pension or other employee benefit plan, payment or
arrangement made to, for or with any such employee, officer, director or
consultant (other than as provided in employment agreements, consulting
agreements and welfare and benefit plans set forth on the Tango Disclosure
Schedule, and except for increases consistent with past practice); (ix) any
material revaluation by Tango or any Tango Subsidiary of any asset (including,
without limitation, any writing down of the value of inventory or writing off
of notes or accounts receivable); (x) any mortgage or pledge of any of the
assets or properties of Tango or any Tango Subsidiary or the subjection of any
of the assets or properties of Tango or any Tango Subsidiary to any material
liens, charges, encumbrances, imperfections of title, security interest,
options or rights or claims of others with respect thereto other than in the
ordinary course consistent with past practice; or (xi) any assumption or
guarantee by Tango or a Tango Subsidiary of the indebtedness of any person or
entity other than in the ordinary course consistent with past practice.

         3.11    Employee Benefit Plans and Employment Matters.

                 (a)      The Section 3.11(a) of the Tango Disclosure Schedule
lists all employee benefit plans, collective bargaining agreements, labor
contracts, and employment agreements not otherwise disclosed in the Tango
Current Reports in which Tango or any Tango Subsidiary participates, or by
which any of them are bound, including, without limitation, (i) any profit
sharing, deferred compensation, bonus, stock option, stock purchase, pension,
welfare, and incentive plan or agreement; (ii) any plan providing for "fringe
benefits" to their employees, including, but not limited to, vacation, sick
leave, medical, hospitalization and life insurance; (iii) any written
employment agreement and any other employment agreement not terminable at will;
and (iv) any other "employee benefit plan" (within the meaning of Section 3(3)
of the Employment Retirement Income Security Act of 1974 ("ERISA")).  Tango and
the Tango Subsidiaries are in compliance in all material respects with the
requirements prescribed by all laws currently in effect applicable to employee
benefit plans and to any employment agreements, including, but not limited to,
ERISA and the Code.  Tango and the Tango Subsidiaries have each performed all
of its obligations under all such employee benefit plans and employment
agreements in all material respects.  There is no pending or, to the knowledge
of Tango, threatened legal action, proceeding or investigation against or
involving any Tango or Tango Subsidiary employee benefit plan which could
result in a material amount of liability to such employee benefit plan or to
Tango.

                 (b)      Neither Tango nor the Tango Subsidiaries sponsor or
participate in, and have not sponsored or participated in, any employee benefit
pension plan to which Section 4021 of ERISA applies that would create a
material amount of liability to Tango under Title IV of ERISA.

                 (c)      Neither Tango nor the Tango Subsidiaries sponsor or
participate in, and have not sponsored or participated in, any employee benefit
pension plan that is a "multiemployer plan" (within the meaning of Section
3(37) of ERISA).

                 (d)      All group health plans of Tango and the Tango
Subsidiaries have been operated in compliance with the group health plan
continuation coverage requirements of Section 4980B of the Code in all material
respects, to the extent such requirements are applicable.

                 (e)      There have been no acts or omissions by Tango or the
Tango Subsidiaries or by any fiduciary, disqualified person or party in
interest with respect to an employee benefit plan of Tango or any Tango
Subsidiaries that have given rise to or may give rise to a material amount of
fines, penalties, taxes, or related charges under Sections 502(c), 502(i) or
4071 of ERISA or under Chapter 43 of the Code.

                 (f)      No "reportable event," as defined in ERISA Section
4043, other than those events with respect to which the Pension Benefit
Guaranty Corporation has waived the notice requirement, has occurred with
respect to any of the employee benefit plans of Tango.







                                      -15-
<PAGE>   21


                 (g)      Section 3.11(g) of the Tango Disclosure Schedule sets
forth the name of each director, officer or employee of Tango or any Tango
Subsidiary entitled to receive any benefit or payment under any existing
employment agreement, severance plan or other benefit plan solely as a result
of the consummation of any transaction contemplated by this Agreement, and with
respect to each such person, the nature of such benefit or the amount of such
payment, the event triggering the benefit or payment, and the date of, and
parties to, such employment agreement, severance plan or other benefit plan.

                 (h)      Tango has furnished Twister with true and correct
copies of all plan documents and employment agreements referred to on the Tango
Disclosure Schedule, including all amendments thereto, and all related summary
plan descriptions to the extent that one is required by law.

                 (i)      For purposes of this Section 3.11, any reference to
"Tango" shall be deemed to include a reference to any entity that is aggregated
with Tango under the provisions of Section 414 of the Code, to the extent that
those aggregation rules apply.

         3.12    Labor Matters.  Except as disclosed on Schedule 3.12 of the
Tango Disclosure Schedule, neither Tango nor any Tango Subsidiary is a party to
any collective bargaining agreement with respect to any of their employees.
None of the employees of Tango or any Tango Subsidiary is represented by any
labor union.  To the knowledge of Tango, there is no activity involving any
employees of Tango or the Tango Subsidiaries seeking to certify a collective
bargaining unit or engaging in any similar organizational activity.

         3.13    Insurance.  Tango and the Tango Subsidiaries maintain
insurance against such risks and in such amounts as Tango reasonably believes
are necessary to conduct its business.  Tango and the Tango Subsidiaries are
not in default with respect to any provisions or requirements of any such
policy, nor have any of them failed to give notice or present any claim
thereunder in a due and timely fashion, except for defaults or failures which,
individually or in the aggregate, would not have a Material Adverse Effect on
Tango.  Neither Tango nor any Tango Subsidiary has received any notice of
cancellation or termination in respect of any of its insurance policies.

         3.14    Environmental Matters.  Except as disclosed on Section 3.14 of
the Tango Disclosure Schedule, Tango and the Tango Subsidiaries are in
compliance with all environmental laws, and have obtained all necessary
licenses and permits required to be issued pursuant to any environmental law,
except where the failure to so comply or to obtain such licenses or permits,
individually or in the aggregate, would not have a Material Adverse Effect on
Tango.  Neither Tango nor any Tango Subsidiary has received notice or
communication from any governmental agency with, respect to (i) any hazardous
substance relative to its operations, property or assets or (ii) any
investigation, demand or request pursuant to enforcing any environmental law
relating to it or its operations, and no such investigation is pending or, to
the knowledge of Tango threatened, in any case, which would lead to a Material
Adverse Effect on Tango.

         3.15    Tax Matters.  Neither Tango nor, to the knowledge of Tango,
any of its affiliates has taken or agreed to take any action that would, nor
does Tango have any knowledge of any fact or circumstance that is reasonably
likely to, prevent the Merger from qualifying as a reorganization under the
provisions of Section 368(a) of the Code.  Tango has paid, or made adequate
provision for on its balance sheet at December 31, 1996 included in the Tango
10-K, all federal, state, local, foreign or other governmental income,
franchise, payroll, F.I.C.A., unemployment, withholding, real property,
personal property, sales, payroll, disability and all other taxes imposed on
Tango or any Tango Subsidiary or with respect to any of their respective
properties, or otherwise payable by them, including interest and penalties, if
any, in respect thereof (collectively, "Tango Taxes"), for the Tango taxable
period ended December 31, 1996 and all fiscal periods of Tango prior thereto,
except such nonpayment, or failure to make adequate provision, which,
individually or in the aggregate, would not have a Material Adverse Effect on
Tango.  Tango Taxes paid and/or incurred from December 31, 1996 until the
Closing Date shall include only Tango Taxes incurred in the ordinary course of
business determined in the same manner as in the taxable period ended December
31, 1996.  Tango and each of the Tango Subsidiaries have timely filed all
income tax, excise tax, sales tax, use tax, gross receipts tax, franchise tax,
employment and payroll related tax, property tax, and all other tax returns
which Tango and/or such Tango Subsidiary (as the case may be) are required to
file ("Tango Tax Returns"), and have paid or provided for all the amounts shown
to be due thereon, except where such failure to make such timely filings,
individually or in the aggregate, would not have a Material Adverse Effect on
Tango, and except for the nonpayment of such amounts which, individually or in
the aggregate, would not have a Material Adverse Effect on Tango.  Neither
Tango nor any Tango Subsidiary (i) has filed or entered into, or is otherwise
bound by, any election, consent or extension agreement that extends any
applicable statute of limitations with respect to taxable periods of Tango,
(ii) is a party to any contractual obligation requiring the indemnification or
reimbursement of any person with respect to the payment of any Tango Taxes,
other than among Tango and the Tango Subsidiaries, or (iii) has received any
claim by an authority in a jurisdiction where neither Tango nor any Tango
Subsidiary files Tango Tax Returns that they are or may be subject to Tango
Taxes by that jurisdiction, except for any such claims as, individually or in
the aggregate, would not have a Material Adverse Effect on Tango.  No action or
proceeding is pending or, to Tango's knowledge, threatened by any governmental
authority for any audit, examination, deficiency, assessment or collection from
Tango or any Tango Subsidiary of any Tango Taxes, no unresolved claim for any
deficiency, assessment or collection of any Tango Taxes has been asserted
against Tango or any Tango Subsidiary, and all resolved assessments of Tango
Taxes have been paid or are reflected on the Tango balance sheet at December
31, 1996 included in the Tango 10-K, except for any of the foregoing which,
individually or in the aggregate, would not have a Material Adverse Effect on
Tango.

         3.16    Intellectual Property.  Except as disclosed in Section 3.16 of
the Tango Disclosure Schedule, Tango and the Tango Subsidiaries own, possess or
have the right to use all franchises, patents, trademarks, service marks,
tradenames, licenses and authorizations (collectively, "Tango Intellectual
Property Rights") which are necessary to the conduct of their respective
businesses.  To the knowledge of Tango, neither Tango nor any Tango Subsidiary
is infringing or otherwise violating the intellectual property rights of any
person which infringement or violation would







                                      -17-
<PAGE>   23

subject Tango or any Tango Subsidiary to liabilities which, individually or in
the aggregate, would have a Material Adverse Effect on Tango or which would
prevent Tango or any Tango Subsidiary from conducting their respective
businesses substantially in the manner in which they are now being conducted.
No claim has been made or, to Tango's knowledge, threatened against Tango or
any Tango Subsidiary alleging any such violation.

         3.17    Related Party Transactions.  Except as disclosed in the Tango
SEC Filings or in Section 3.17 of the Tango Disclosure Schedule, there have
been no material transactions between Tango or any Tango Subsidiary on the one
hand, and any (i) officer or director of Tango or any Tango Subsidiary, (ii)
record or beneficial owner of five percent or more of the voting securities of
Tango, or (iii) affiliate (as such term is defined in Regulation 12b-2
promulgated under the Exchange Act) of any such officer, director or beneficial
owner, on the other hand, other than payment of compensation for services
rendered to Tango or the Tango Subsidiaries or the grant of stock options to
purchase shares of Tango Common Stock.

         3.18    No Undisclosed Material Liabilities.  Except as disclosed in
the Tango Current Reports, neither Tango nor any of the Tango Subsidiaries has
incurred any liabilities of any kind whatsoever, whether accrued, contingent,
absolute, determined, determinable or otherwise, that, individually or in the
aggregate, would have a Material Adverse Effect on Tango other than (i)
liabilities incurred in the ordinary course of business consistent with past
practice since December 31, 1996, (ii) liabilities that have been repaid,
discharged or otherwise extinguished, and (iii) liabilities under or
contemplated by this Agreement.

         3.19    No Default.  Except as set forth in Section 3.19 of the Tango
Disclosure Schedule, neither Tango nor any of the Tango Subsidiaries is in
default or violation (and no event has occurred which with notice or the lapse
of time or both would constitute a default or violation) of any term, condition
or provision of (a) its certificate of incorporation or bylaws or other
organizational documents, (b) indenture, mortgage, note, bond, lien, lease,
license, agreement, franchise, contract, order, judgment, ordinance, Tango
Permit or other instrument or obligation to which Tango or any Tango Subsidiary
is a party or by which Tango or any Tango Subsidiary or any of their respective
properties is bound or subject to, or (c) any order, writ, injunction, decree
or Law applicable to Tango or any of the Tango Subsidiaries, except in the case
of clauses (b) and (c) above for defaults or violations which would not have a
Material Adverse Effect on Tango.

         3.20    Title to Properties; Encumbrances.  Section 3.20 of the Tango
Disclosure Schedule sets forth all real property owned or leased by Tango and
the Tango Subsidiaries (the "Tango Real Property"), indicating which facilities
are owned and which are leased.  Except as disclosed in the Tango Current
Reports and as described in clause (ii) below: (i) each of Tango and the Tango
Subsidiaries has good, valid and marketable title to, or a valid leasehold
interest in, as applicable, all of its properties and assets (real, personal
and mixed, tangible and intangible), including, without limitation, all Tango
Real Property and all other properties and assets reflected in the consolidated
balance sheet of Tango and the Tango Subsidiaries at December 31, 1996 included
in the Tango 10-K (except for properties and assets disposed of in







                                      -18-
<PAGE>   24

the ordinary course of business and consistent with past practices since
December 31, 1996) and (ii) none of such properties or assets are subject to
any liability, obligation, claim, lien, mortgage, pledge, security interest,
conditional sale agreement, charge or encumbrance of any kind (whether
absolute, accrued, contingent or otherwise), except for liens securing
repayment of indebtedness incurred in the ordinary course consistent with past
practices subsequent to March 31, 1997 and liens for taxes not yet due and
payable, easements and restrictions of record, unrecorded and undelivered
mortgages between a Tango Subsidiary and a joint venture entity in which Tango
is a limited partner or a managing member and minor imperfections of title and
encumbrance, if any, which are not substantial in amount, do not materially
detract from the value of the property or assets subject thereto and do not
impair the operations of Tango and the Tango Subsidiaries.  Each of the leases
is in full force and effect and there is no default by landlord or tenant
existing thereunder (and no event has occurred which, with notice and the
passage of time or both, would constitute a default under such lease) which
would have a Material Adverse Effect on Tango.  Except as would not cause a
Material Adverse Effect on Tango, all of the properties and assets of Tango and
the Tango Subsidiaries are, in all material respects, in good operating
condition and repair, and maintenance thereon has not been deferred beyond
industry standards, and are suitable for the purposes for which they are
presently being used.

         3.21    Pooling of Interests.  Neither Tango nor any of the Tango
Subsidiaries nor, to the knowledge of Tango, any of their respective directors,
officers or stockholders has taken any action which would interfere with the
parties' ability to account for the Merger as a "pooling of interests" in
accordance with Accounting Principles Board Opinion No.  16, the interpretive
releases issued pursuant thereto, and the pronouncements of the Commission.

         3.22    Brokers.  Neither Tango nor any Tango Subsidiary has paid or
is obligated to pay any brokerage, finder's or other fee or commission to any
broker, finder, investment banker or other intermediary in connection with this
Agreement or the Cross Option Agreement, except that Tango has retained
McDonald & Company Securities, Inc. as its financial advisor for the
transactions contemplated hereby.

         3.23    Opinion of Financial Advisor.  Tango has received the opinion
of McDonald & Company Securities, Inc. to the effect that, as of the date
hereof, the consideration to be paid to the holders of shares of Twister Common
Stock pursuant to this Agreement is fair to Tango, from a financial point of
view.

         3.24    Twister Stock Ownership.  Except as contemplated pursuant to
the terms of this Agreement and the transactions to be consummated hereby or by
the Cross Option Agreement, neither Tango nor any of the Tango Subsidiaries own
any shares of Twister Common Stock or rights to acquire or dispose of Twister
Common Stock.

                                   ARTICLE IV
                   REPRESENTATIONS AND WARRANTIES OF TWISTER

         Twister represents and warrants to Tango and Merger Sub that, except
as set forth in the Disclosure Schedule delivered prior hereto (the "Twister
Disclosure Schedule"), which shall identify exceptions by specific Section
references:

         4.1     Corporate Organization.  Twister and each of its Subsidiaries
(the "Twister Subsidiaries") has been duly organized and is validly existing
and in good standing under the laws of the jurisdiction of its organization,
has all requisite power and authority to own, operate and lease its properties
and to carry on its business as it is now being conducted, and is qualified or
licensed to do business and is in good standing in each jurisdiction in which
the nature of the business conducted by it or the ownership or leasing of its
properties makes such qualification necessary, other than where failure to be
so qualified or licensed, individually or in the aggregate, would not have a
Material Adverse Effect on Twister.  The term "Material Adverse Effect on
Twister" as used in this Agreement shall mean any change or effect that,
individually or when taken together with all such other changes or effects,
would be materially adverse to the financial condition, results of operations,
properties or business of Twister and the Twister Subsidiaries taken as a whole
at the time of such change or effect.  True and complete copies of the Articles
of Incorporation and the Bylaws together with all amendments thereto of Twister
and the Articles of Incorporation of the Twister Subsidiaries, together with
all amendments thereto have been heretofore delivered to Tango.  Such charter,
Bylaws or other organizational documents are in full force and effect.  Section
4.1 of the Twister Disclosure Schedule contains a complete and accurate list of
all of the Twister Subsidiaries.  Neither Twister nor any Twister Subsidiary is
in violation of any provision of its charter or bylaws or other organizational
documents of limited partnership, as the case may be.

         4.2     Capitalization.  As of the date of this Agreement, the
authorized capital stock of Twister consists in its entirety of (i) 75,000,000
shares of common stock, no par value, and (ii) 20,000,000 shares of preferred
stock, none of which are issued and outstanding.  As of the date of the
Agreement, (i) 5,041,931 shares of Twister Common Stock were issued and
outstanding, (ii) options and warrants to acquire 376,969 shares of Twister
Common Stock were outstanding under the Twister Option Plans (as hereinafter
defined) and (iii) 1,561,106 shares of Twister Common Stock were reserved for
issuance upon conversion of Twister's $35,000,000 principal amount of aggregate
outstanding 6.75% Convertible Subordinated Debentures Due 2006.  Except as set
forth on Section 4.2 of the Twister Disclosure Schedule, all of the outstanding
shares of capital stock of each of the Twister Subsidiaries is owned
beneficially and of record by Twister or a Twister Subsidiary free and clear of
all liens, charges, encumbrances, options, rights of first refusal or
limitations or agreements regarding voting rights of any nature.  All of the
outstanding shares of capital stock of Twister and each of the Twister
Subsidiaries have been duly authorized, validly issued and are fully paid and
nonassessable and are not subject to preemptive rights created by statute,
their respective charter or bylaws or any agreement to which any such entity is

warrants to purchase Twister Common Stock, in each case as currently in effect.
Each option agreement, together with any related award letter, sets forth for
each stock option holder (i) such holder's name, (ii) the date of grant of
stock options to such holder, (iii) the number of shares of Twister Common
Stock into which each such grant is exercisable, (iv) the exercise price per
share of Twister Common Stock with respect to each such grant, and (v) the
periods during which such stock options or portions thereof are exercisable by
such holder.  Except as set forth in this Section 4.2 or in Section 4.2 of the
Twister Disclosure Schedule, there are no options, warrants or other rights
(including registration rights), agreements, arrangements or commitments of any
character to which Twister or any Twister Subsidiary is a party relating to the
issued or unissued capital stock, or other interest in, of Twister or any
Twister Subsidiary or obligating Twister or any Twister Subsidiary to grant,
issue or sell any shares of capital stock of, or other equity interests in,
Twister or any Twister Subsidiary, by sale, lease, license or otherwise.  All
shares of Twister Common Stock subject to issuance as aforesaid, upon issuance
on the terms and conditions specified in the instruments pursuant to which they
are issuable, will be duly authorized, validly issued, fully paid and
nonassessable and will not have been issued in violation of or subject to any
preemptive rights created by statute, the articles of incorporation or bylaws
of Twister or any agreement to which Twister is a party or to which Twister is
bound.  Except as set forth in this Section 4.2 or in the Twister Current
Reports, (hereinafter defined), there are no outstanding contractual
obligations of Twister or any Twister Subsidiary to (x) repurchase, redeem or
otherwise acquire any shares of Twister Common Stock or any capital stock, or
other interests in, of any Twister Subsidiary, (y) except for guarantees of
obligations of, or loans to or capital contribution commitments, Twister
Subsidiaries entered into in the ordinary course of business, provide funds to,
make any investment in (in the form of a loan, capital contribution or
otherwise) or provide any guarantee with respect to the obligations of, any
Twister Subsidiary or any other person.  Each outstanding share of capital
stock, or other interest in, of each Twister Subsidiary is duly authorized,
validly issued, fully paid and nonassessable and, except as set forth in
Section 4.2 of the Twister Disclosure Schedule, each such share owned by
Twister or another Twister Subsidiary is owned free and clear of all security
interests, liens, claims, pledges, options, rights of first refusal,
agreements, limitations on Twister's or such other Twister Subsidiary's voting
rights, charges and other encumbrances of any nature whatsoever.

         4.3     Options or Other Rights.

                 (a)      Except as disclosed in Section 4.2 or in the Twister
SEC Filings (hereinafter defined), there is no outstanding right, subscription,
warrant, call, unsatisfied preemptive right, option or other agreement or
arrangement of any kind to purchase or otherwise to receive from Twister or any
Twister Subsidiary any of the outstanding, authorized but unissued,
unauthorized or treasury shares of the capital stock or any other security of
Twister or any Twister Subsidiary and there is no outstanding security of any
kind convertible into or exchangeable for such capital stock.  Except as set
forth in Section 4.3 of the Twister Disclosure Schedule, there are no
agreements or understandings among Twister or any Twister Subsidiary on the one
hand and any other person on the other hand concerning the registration of any
security of Twister or a Twister Subsidiary under the Securities Act.  Except
as set forth on

Section 4.3 of the Twister Disclosure Schedule, all options granted under the
Twister Option Plans have provisions which accelerate the vesting or right to
exercise such options upon the occurrence of certain events, including, but not
limited to, the consummation of the Merger.

                 (b)      Prior to the execution and delivery of this
Agreement, Twister has entered into Amendment No. 1 to that certain Rights
Agreement dated as of June 25, 1997 (the "Rights Agreement"), between Twister
and ChaseMellon Shareholder Services, L.L.C., as rights agent, pursuant to
which amendment the definition of "Acquiring Person" in Section 1(a) of the
Rights Agreement will be amended as set forth on Section 4.3(b) of the Twister
Disclosure Schedule.

         4.4     Authority Relative to this Agreement.  Twister has all
requisite corporate power and authority to execute and deliver this Agreement
and the Cross Option Agreement, to perform its obligations hereunder and
thereunder and to consummate the transactions contemplated on its part hereby
and thereby to be consummated by Twister.  The execution and delivery of this
Agreement and the Cross Option Agreement by Twister and the consummation of the
transactions contemplated on its part hereby and thereby have been duly
authorized by all necessary corporate action, and, other than the approval of
Twister's stockholders as provided in Section 5.1 hereof, no other corporate
proceedings on the part of Twister are necessary to authorize the execution and
delivery of this Agreement and the Cross Option Agreement by Twister or the
consummation of the transactions contemplated on its part hereby and thereby.
This Agreement and the Cross Option Agreement have been duly executed and
delivered by Twister and, assuming the due authorization, execution and
delivery hereof and thereof by Tango and Merger Sub, constitutes the legal,
valid and binding obligations of Twister, enforceable against Twister in
accordance with their respective terms, except to the extent that such
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization or other laws affecting the enforcement of creditors' rights
generally or by general equity principles.

         4.5     No Violation.  The execution and delivery of this Agreement
and of the Cross Option Agreement by Twister do not, the performance by Twister
of its obligations hereunder and thereunder will not, and the consummation by
Twister of the transactions contemplated to be performed by it hereby and
thereby will not (i) violate or conflict with any provision of any Laws in
effect on the date of this Agreement and applicable to Twister or any Twister
Subsidiary or by which any of their respective properties or assets is bound or
subject, (ii) require Twister or any Twister Subsidiary to obtain any consent,
waiver, approval, license or authorization or permit of, or make any filing
with, or notification to, any Governmental Entities, based on laws, rules,
regulations and other requirements of Governmental Entities in effect and of
the date of this Agreement (other than (a) the filing of a Pre-Merger
Notification Report under the HSR Act and the expiration of the applicable
waiting period, (b) filings or authorizations required in connection or in
compliance with the provisions of the Exchange Act, the Securities Act, the
KGCC, the Bylaws of the AMEX or the "takeover" or "blue sky" laws of various
states and (c) any other filings and approvals expressly contemplated by this

Twister Disclosure Schedule, (iv) violate, conflict with or result in a breach
of or the







                                      -22-

acceleration of any obligation under, or constitute a default (or an event
which with notice or the lapse of time or both would become a default) under,
or give to others any rights of, or result in any, termination, amendment,
acceleration or cancellation of, or loss of any benefit or creation of a right
of first refusal, or require any payment under, or result in the creation of a
lien or other encumbrance on any of the properties or assets of Twister or any
Twister Subsidiary pursuant to or under any provision of any indenture,
mortgage, note, bond, lien, lease, license, agreement, contract, order,
judgment, ordinance, Twister Permit (as defined below) or other instrument or
obligation to which Twister or Twister Subsidiary is a party or by which
Twister or any Twister Subsidiary or any of their respective properties is
bound or subject to, or (v) conflict with or violate the Articles of
Incorporation or Bylaws, or the equivalent organizational documents, in each
case as amended or restated, of Twister or any of the Twister Subsidiaries,
except for any such conflicts or violations described in clause (i) or
breaches, defaults, events, rights of termination, amendment, acceleration or
cancellation, payment obligations or liens or encumbrances described in clause
(iv) that would not have a Material Adverse Effect on Twister and except where
the failure to obtain such consents, approvals, authorizations or permits, or
to make such filings or notifications would not, either individually or in the
aggregate, prevent Twister from performing any of its obligations under this
Agreement or the Cross Option Agreement and would not have a Material Adverse
Effect on Twister.  Neither Twister nor any of its affiliates or associates (as
each such term is defined in Section 203 of the DGCL) is, prior to the date
hereof, an "interested stockholder" (as such term is defined in Section 203 of
the DGCL) of Tango.

         4.6     Compliance with Laws.

                 (a)      As of the date of this Agreement, each of Twister and
the Twister Subsidiaries holds all licenses, franchises, grants, permits,
easements, variances, exemptions, consents, certificates, identification
numbers, approvals, orders, and other authorizations (collectively, "Twister
Permits") necessary to own, lease and operate its properties and to carry on
its business as it is now being conducted, are certified as providers under all
applicable Medicare and Medicaid programs to the extent required to be so
certified, and are in compliance with all Twister Permits and all Laws
governing their respective businesses, including, without limitation, the
requirements, guidelines, rules and regulations of Medicare, Medicaid, state
approved Medicaid waiver programs and other third-party reimbursement programs,
except where the failure to hold such Twister Permits or to so comply,
individually or in the aggregate, would not have a Material Adverse Effect on
Twister.

                 (b)      To Twister's knowledge, all health care personnel
employed by Twister or any Twister Subsidiary are properly licensed to the
extent required to perform the duties of their employment in each jurisdiction
where such duties are performed, except where the failure to be so licensed,
individually or in the aggregate, would not have a Material Adverse Effect on
Twister.

                 (c)      Except as set forth in Section 4.6(c) of the Twister
Disclosure Schedule, no action or proceeding is pending or, to Twister's
knowledge, threatened that may result in the







                                      -23-
<PAGE>   29

suspension, revocation or termination of any Twister Permit, the issuance of
any cease-and-desist order, or the imposition of any administrative or judicial
sanction, and neither Twister nor any Twister Subsidiary has received any
notice from any governmental authority in respect of the suspension, revocation
or termination of any Twister Permit, or any notice of any intention to conduct
any investigation or institute any proceeding, in any such case where such
suspension, revocation, termination, order, sanction, investigation or
proceeding would result, individually or in the aggregate, in a Material
Adverse Effect on Twister.

                 (d)      Neither Twister nor any Twister Subsidiary has
received notice that Medicare, Medicaid, state approved Medicaid waiver
programs or any other third-party reimbursement program has any claims for
disallowance of costs against any of them which could result in offsets against
future reimbursement or recovery of prior payments, which offsets or
recoveries, individually or in the aggregate, would have a Material Adverse
Effect on Twister.

         4.7     Litigation.  As of the date of this Agreement, except as may
be disclosed in the Twister 10-K (as defined below), reports filed on Forms
10-Q or 8-K or proxy statements filed on Schedule 14-A for periods subsequent
to the period covered by such Twister 10-K, in each case filed prior to the
date hereof (such reports and filings, collectively, the "Twister Current
Reports"), or except as set forth on Section 4.7 of the Twister Disclosure
Schedule, there is no claim, litigation, suit, arbitration, mediation, action,
proceeding, unfair labor practice complaint or grievance pending or, to
Twister's knowledge, investigation of any kind, at law or in equity (including
actions or proceedings seeking injunctive relief), pending or, to Twister's
knowledge, threatened in writing against Twister or any Twister Subsidiary or
with respect to any property or asset of any of them, except for claims,
litigations, suits, arbitrations, mediations, actions, proceedings, complaints,
grievances or investigations which, individually or in the aggregate, would not
have a Material Adverse Effect on Twister.  Neither Twister nor any Twister
Subsidiary nor any property or asset of any of them is subject to any
continuing order, judgment, settlement agreement, injunction, consent decree or
other similar written agreement with or, to Twister's knowledge, continuing
investigation by, any Governmental Entity, or any judgment, order, writ,
injunction, consent decree or award of any Governmental Entity or arbitrator,
including, without limitation, cease-and-desist or other orders, except for
such matters which would not reasonably be expected to have a Material Adverse
Effect on Twister.

         4.8     Financial Statements and Reports.  Twister has made available
to Tango true and complete copies of (i) its Annual Report on Form 10-K for the
year ended December 31, 1996 (the "Twister 10-K"), as filed with the
Commission, (ii) its proxy statement relating to the annual meetings of its
stockholders held on May 23, 1997, (iii) all registration statements filed by
Twister and declared effective under the Securities Act (other than
registration statements on Form S-8) and (iv) all other reports, statements and
registration statements (including Quarterly Reports on Form 10-Q and Current
Reports on Form 8-K but excluding preliminary material and reports pursuant to
Sections 13(d) or 13(g) of the Exchange Act) filed by it with the Commission.
The reports, statements and registration statements referred to in the
immediately preceding sentence (including, without limitation, any financial
statements or schedules or other







                                      -24-
<PAGE>   30

information included or incorporated by reference therein) are referred to in
this Agreement as the "Twister SEC Filings."  As of the respective times such
documents were filed or, as applicable, were effective, the Twister SEC Filings
complied in all material respects with the requirements of the Securities Act
or the Exchange Act, as the case may be, and the rules and regulations
promulgated thereunder, except for such noncompliance which, individually or in
the aggregate, would not have a Material Adverse Effect on Twister, and did not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading.  The
financial statements of Twister included in the Twister SEC Filings comply as
to form in all material respect with applicable accounting requirements and
with the published rules and regulations of the Commission with respect
thereto, were prepared in accordance with generally accepted accounting
principles (as in effect from time to time) applied on a consistent basis
during the periods involved (except as may be indicated therein or in the notes
thereto or, in the case of the unaudited interim financial statements, as
permitted by Form 10-Q of the Commission) and present fairly the consolidated
financial position, consolidated results of operations and consolidated cash
flows of Twister and the Twister Subsidiaries as of the dates and for the
periods indicated, except (i) in the case of unaudited interim consolidated
financial statements, to normal recurring year-end adjustments and any other
adjustments described therein and (ii) any pro forma financial information
contained therein is not necessarily indicative of the consolidated financial
position of Twister and the Twister Subsidiaries as of the respective dates
thereof and the consolidated results of operations and cash flows for the
periods indicated.  No Twister Subsidiary is required to file any form, report
or other document with the Commission.

         4.9     Absence of Certain Changes or Events.  Other than as disclosed
in the Twister Current Reports, or otherwise disclosed in this Agreement or in
Section 4.9 of the Twister Disclosure Schedule, since December 31, 1996 and
through the date hereof, the business of Twister and of each of the Twister
Subsidiaries has been conducted in the ordinary course, and there has not been
(i) any Material Adverse Effect on Twister; (ii) any material indebtedness
incurred by Twister or any Twister Subsidiary for money borrowed, except under
credit facilities disclosed in the Twister SEC Current Reports, if any; (iii)
any material transaction or commitment, except in the ordinary course of
business or as contemplated by this Agreement, entered into by Twister or any
of the Twister Subsidiaries; (iv) any damage, destruction or loss, whether

have a Material Adverse Effect on Twister; (v) any material change by Twister
in accounting principles or methods except insofar as may be required by a
change in generally accepted accounting principles; (vi) any declaration,
setting aside or payment of any dividend (whether in cash, securities or
property) with respect to the Twister Common Stock; or (vii) any material

(viii) any increase in the compensation payable or to become payable by Twister
or any Twister Subsidiary to any employees, officers, directors, or consultants
or in any bonus, insurance, welfare, pension or other employee benefit plan,
payment or arrangement made to, for or with any such employee, officer,
director or consultant (other than as provided in employment agreements,
consulting agreements and welfare and benefit plans set forth on the Twister
Disclosure Schedule, and







                                      -25-

except for increases consistent with past practice); (ix) any material
revaluation by Twister or any Twister Subsidiary of any asset (including,
without limitation, any writing down of the value of inventory or writing off
of notes or accounts receivable); (x) any mortgage or pledge of any of the
assets or properties of Twister or any Twister Subsidiary or the subjection of
any of the assets or properties of Twister or any Twister Subsidiary to any
material liens, charges, encumbrances, imperfections of title, security
interest, options or rights or claims of others with respect thereto other than
in the ordinary course consistent with past practice; or (xi) any assumption or
guarantee by Twister or a Twister Subsidiary of the indebtedness of any person
or entity, other than in the ordinary course consistent with past practice.

         4.10    Employee Benefit Plans and Employment Matters.

                 (a)      Section 4.10(a) of the Twister Disclosure Schedule
lists all employee benefit plans, collective bargaining agreements, labor
contracts, and employment agreements not otherwise disclosed in the Twister
Current Reports in which Twister or any Twister Subsidiary participates, or by
which any of them are bound, including, without limitation, (i) any profit
sharing, deferred compensation, bonus, stock option, stock purchase, pension,
welfare, and incentive plan or agreement; (ii) any plan providing for "fringe
benefits" to their employees, including, but not limited to, vacation, sick
leave, medical, hospitalization and life insurance; (iii) any written
employment agreement and any other employment agreement not terminable at will;
and (iv) any other "employee benefit plan" (within the meaning of Section 3(3)
of ERISA).  Twister and the Twister Subsidiaries are in compliance in all
material respects with the requirement prescribed by all laws currently in
effect applicable to employee benefit plans and to any employment agreement,
including, but not limited to, ERISA and the Code.  Twister and the Twister
Subsidiaries have each performed all of its obligations under all such employee
benefit plans and employment agreements in all material respects.  There is no
pending or, to the knowledge of Twister, threatened legal action, proceeding or
investigation against or involving any Twister or Twister Subsidiary employee
benefit plan which could result in a material amount of liability to such
employee benefit plan or to Twister.

                 (b)      Neither Twister nor the Twister Subsidiaries sponsor
or participate in, and have not sponsored or participated in, any employee
benefit pension plan to which Section 4021 of ERISA applies that would create a
material amount of liability to Twister under Title IV of ERISA.

                 (c)      Neither Twister nor the Twister Subsidiaries sponsor
or participate in, and have not sponsored or participated in, any employee
benefit pension plan that is a "multiemployer plan" (within the meaning of
Section 3(37) of ERISA).

                 (d)      All group health plans of Twister and the Twister
Subsidiaries have been operated in compliance with the group health plan
continuation coverage requirements of Section 4980B of the Code in all material
respects, to the extent such requirements are applicable.







                                      -26-
<PAGE>   32

                 (e)      There have been no acts or omissions by Twister or
any Twister Subsidiary or by any fiduciary, disqualified person or party in
interest with respect to an employee benefit plan of Twister or any Twister
Subsidiaries that have given rise to or may give rise to a material amount of
fines, penalties, taxes, or related charges under Sections 502(c), 502(i) or
4071 of ERISA or under Chapter 43 of the Code.

                 (f)      No "reportable event," as defined in ERISA Section
4043, other than those events with respect to which the Pension Benefit
Guaranty Corporation has waived the notice requirement, has occurred with
respect to any of the employee benefit plans of Twister.

                 (g)      Section 4.10(g) of the Twister Disclosure Schedule
sets forth the name of each director, officer or employee of Twister or any
Twister Subsidiary entitled to receive any benefit or payment under any
existing employment agreement, severance plan or other benefit plan solely as a
result of the consummation of any transaction contemplated by this Agreement,
and with respect to each such person, the nature of such benefit or the amount
of such payment, the event triggering the benefit or payment, and the date of,
and parties to, such employment agreement, severance plan or other benefit
plan.

                 (h)      Twister has furnished Tango with true and correct
copies of all plan documents and employment agreements referred to on the
Twister Disclosure Schedule, including all amendments thereto, and all related
summary plan descriptions to the extent that one is required by law.

                 (i)      For purposes of this Section 4.10, any reference to
"Twister" shall be deemed to include a reference to any entity that is
aggregated with Twister under the provisions of Section 414 of the Code, to the
extent that those aggregation rules apply.

         4.11    Labor Matters.  Neither Twister nor any Twister Subsidiary is
a party to any collective bargaining agreement with respect to any of their
employees.  None of the employees of Twister or any Twister Subsidiary is
represented by any labor union.  To the knowledge of Twister, there is no
activity involving any employees of Twister or the Twister Subsidiaries seeking
to certify a collective bargaining unit or engaging in any similar
organizational activity.

         4.12    Insurance.  Twister and the Twister Subsidiaries maintain
insurance against such risks and in such amounts as Twister reasonably believes
are necessary to conduct its business.  Twister and the Twister Subsidiaries
are not in default with respect to any provisions or requirements of any such
policy, nor have any of them failed to give notice or present any claim
thereunder in a due and timely fashion, except for defaults or failures which,
individually or in the aggregate, would not have a Material Adverse Effect on
Twister.  Neither Twister nor any Twister Subsidiary has received any notice of
cancellation or termination in respect of any of its insurance policies.

         4.13    Environmental Matters.  Except as disclosed in Section 4.13 of
the Twister Disclosure Schedule, Twister and the Twister Subsidiaries are in
compliance with all







                                      -27-
<PAGE>   33

environmental laws, and have obtained all necessary licenses and permits
required to be issued pursuant to any environmental law, except where the
failure to so comply or to obtain such licenses or permits, individually or in
the aggregate, would not have a Material Adverse Effect on Twister.  Neither
Twister nor any Twister Subsidiary has received notice or communication from
any governmental agency with respect to (i) any hazardous substance relative to
its operations, property or assets or (ii) any investigation, demand or request
pursuant to enforcing any environmental law relating to it or its operations,
and no such investigation is pending or, to the knowledge of Twister
threatened, in any case, which would lead to a Material Adverse Effect on
Twister.

         4.14    Tax Matters.  Neither Twister nor, to the knowledge of
Twister, any of its affiliates has taken or agreed to take any action that
would, nor does Twister have any knowledge of any fact or circumstance that is
reasonably likely to, prevent the Merger from qualifying as a reorganization
under the provisions of Section 368 (a) of the Code.  Twister has paid, or made
adequate provision for on its December 31, 1996 balance sheet, all federal,
state, local, foreign or other governmental income, franchise, payroll,
F.I.C.A., unemployment, withholding, real property, personal property, sales,
payroll, disability and all other taxes imposed on Twister or any Twister
Subsidiary or with respect to any of their respective properties, or otherwise
payable by them, including interest and penalties, if any, in respect thereof
(collectively, "Twister Taxes"), for the Twister taxable period ended December
31, 1996 and all fiscal periods of Twister prior thereto, except such
nonpayment, or failure to make adequate provision, which, individually or in
the aggregate, would not have a Material Adverse Effect on Twister and except
as set forth in Section 4.14 to the Twister Disclosure Schedule.  Twister Taxes
paid and/or incurred from December 31, 1996 until the Closing Date shall
include only Twister Taxes incurred in the ordinary course of business
determined in the same manner as in the taxable period ending on December 31,
1996.  Twister and each of the Twister Subsidiaries have timely filed all
income tax, excise tax, sales tax, use tax, gross receipts tax, franchise tax,
employment and payroll related tax, property tax, and all other tax returns
which Twister and/or such Twister Subsidiary (as the case may be) are required
to file ("Twister Tax Returns"), and have paid or provided for all the amounts
shown to be due thereon, except where such failure to make such timely filings,
individually or in the aggregate, would not have a Material Adverse Effect on
Twister, and except for the nonpayment of such amounts which, individually or
in the aggregate, would not have a Material Adverse Effect on Twister.  Neither
Twister nor any Twister Subsidiary (i) has filed or entered into, or is
otherwise bound by, any election, consent or extension agreement that extends
any applicable statute of limitations with respect to taxable periods of
Twister, (ii) is a party to any contractual obligation requiring the
indemnification or reimbursement of any person with respect to the payment of
any Twister Taxes, other than among Twister and the Twister Subsidiaries, or
(iii) has received any claim by an authority in a jurisdiction where neither
Twister nor any Twister Subsidiary files Twister Tax Returns that they are or
may be subject to Twister Taxes by that jurisdiction, except for any such
claims as, individually or in the aggregate, would not have a Material Adverse
Effect on Twister.  No action or proceeding is pending or, to Twister's
knowledge, threatened by any governmental authority for any audit, examination,
deficiency, assessment or collection from Twister or any Twister Subsidiary of
any Twister Taxes, no unresolved claim for any deficiency,







                                      -28-
<PAGE>   34

assessment or collection of any Twister Taxes has been asserted against Twister
or any Twister Subsidiary, and all resolved assessments of Twister Taxes have
been paid or are reflected on the Twister balance sheet at December 31, 1996
included in the Twister 10-K, except for any of the foregoing which,
individually or in the aggregate, would not have a Material Adverse Effect on
Twister.

         4.15    Intellectual Property.  Except as disclosed in Section 4.15 of
the Twister Disclosure Schedule, Twister and the Twister Subsidiaries own,
possess or have the right to use all franchises, patents, trademarks, service
marks, tradenames, licenses and authorizations (collectively, "Twister
Intellectual Property Rights") which are necessary to the conduct of their
respective businesses.  To the knowledge of Twister, neither Twister nor any
Twister Subsidiary is infringing or otherwise violating the intellectual
property rights of any person which infringement or violation would subject
Twister or any Twister Subsidiary to liabilities which, individually or in the
aggregate, would have a Material Adverse Effect on Twister or which would
prevent Twister or any Twister Subsidiary from conducting their respective
businesses substantially in the manner in which they are now being conducted.
No claim has been made or, to Twister's knowledge, threatened against Twister
or any Twister Subsidiary alleging any such violation.

         4.16    Related Party Transactions.  Except as disclosed in the
Twister SEC Filings or in Section 4.16 of the Twister Disclosure Schedule,
there have been no material transactions between Twister or any Twister
Subsidiary on the one hand, and any (i) officer or director of Twister or any
Twister Subsidiary, (ii) record or beneficial owner of five percent or more of
the voting securities of Twister or (iii) affiliate (as such term is defined in
Regulation 12b-2 promulgated under the Exchange Act) of any such officer,
director or beneficial owner, on the other hand, other than payment of
compensation for services rendered to Twister or the Twister Subsidiaries or
the grant of stock options to purchase shares of Twister Common Stock.

         4.17    No Undisclosed Material Liabilities.  Except as disclosed in
the Twister Current Reports, neither Twister nor any of the Twister
Subsidiaries has incurred any liabilities of any kind whatsoever, whether
accrued, contingent, absolute, determined, determinable or otherwise, that,
individually or in the aggregate, would have a Material Adverse Effect on
Twister other than (i) liabilities incurred in the ordinary course of business
consistent with past practice since December 31, 1996, (ii) liabilities that
have been repaid, discharged or otherwise extinguished and (iii) liabilities
under or contemplated by this Agreement.

         4.18    No Default.  Except as set forth in Section 4.18 of the
Twister Disclosure Schedule, neither Twister nor any of the Twister
Subsidiaries is in default or violation (and no event has occurred which with
notice or the lapse of time or both would constitute a default or violation) of
any term, condition or provision of (a) its charter or bylaws or other
organizational document, (b) indenture, mortgage, note, bond, lien, lease,
license, agreement, contract, order, judgment, ordinance, Twister Permit or
other instrument or obligation to which Twister or Twister Subsidiary is a
party or by which Twister or any Twister Subsidiary or any of their respective
properties is bound or subject to, or (c) any order, writ, injunction, decree
or Law







                                      -29-
<PAGE>   35

applicable to Twister or any of the Twister Subsidiaries, except in the case of
clauses (b) and (c) above for defaults or violations which would not have a
Material Adverse Effect on Twister.

         4.19    Title to Properties; Encumbrances.  Section 4.19 of the
Twister Disclosure Schedule sets forth all real property owned or leased by
Twister and the Twister Subsidiaries (the "Twister Real Property"), indicating
which facilities are owned and which are leased.  Except as disclosed in the
Twister Current Reports and as described in clause (ii) below:  (i) each of
Twister and the Twister Subsidiaries has good, valid and marketable title to,
or a valid leasehold interest in, as applicable, all of its properties and
assets (real, personal and mixed, tangible and intangible), including, without
limitation, all Twister Real Property and all the other properties and assets
reflected in the consolidated balance sheet of Twister and the Twister
Subsidiaries at December 31, 1996 (except for properties and assets disposed of
in the ordinary course of business and consistent with past practices since
December 31, 1996) and (ii) none of such properties or assets are subject to
any liability, obligation, claim, lien, mortgage, pledge, security interest,
conditional sale agreement, charge or encumbrance of any kind (whether
absolute, accrued, contingent or otherwise), except for liens securing
repayment of indebtedness incurred in the ordinary course consistent with past
practice subsequent to March 31, 1997 and liens for taxes not yet due and
payable, easements and restrictions of record, unrecorded and undelivered
mortgages between a Twister Subsidiary and a joint venture entity in which
Twister is a limited partner or a managing member and minor imperfections of
title and encumbrance, if any, which are not substantial in amount, do not
materially detract from the value of the property or assets subject thereto and
do not impair the operations of Twister and the Twister Subsidiaries.  Each of
the leases is in full force and effect and there is no default by landlord or
tenant existing thereunder (and no event has occurred which, with notice and
the passage of time or both, would constitute a default under such lease) which
would have a Material Adverse Effect on Twister.  Except as would not cause a
Material Adverse Effect on Twister, all of the properties and assets of Twister
and the Twister Subsidiaries are, in all material respects, in good operating
condition and repair, and maintenance thereon has not been deferred beyond
industry standards, and are suitable for the purposes for which they are
presently being used.

         4.20    Pooling of Interests.  Neither Twister nor any of the Twister
Subsidiaries nor, to the knowledge of Twister, any of their respective
directors, officers or stockholders has taken any action which would interfere
with the parties' ability to account for the Merger as a "pooling of interests"
in accordance with Accounting Principles Board Opinion No. 16, the interpretive
releases issued pursuant thereto, and the pronouncements of the Commission.

         4.21    Brokers.  Except as set forth in Section 4.21 of the Twister
Disclosure Schedule, neither Twister nor any Twister Subsidiary has paid or is
obligated to pay any brokerage, finders or other fee or commission to any
broker, finder, investment banker or other intermediary in connection with this
Agreement or the Cross Option Agreement, except that Twister has retained
Schroder & Co. Inc. as its financial advisor for the transactions contemplated
hereby.

         4.22    Opinion of Financial Advisor.  Twister has received the
opinion of Schroder & Co. Inc. to the effect that, as of the date hereof,
consideration to be paid to the holders of shares







                                      -30-
<PAGE>   36

of Twister Common Stock pursuant to this Agreement is fair to the holders of
Twister Common Stock, from a financial point of view.

         4.23    Contracts.  Except as set forth in Section 4.24 of the Twister
Disclosure Schedule, neither Twister nor any Twister Subsidiary has entered
into any agreement involving amounts in excess of $50,000 which is not
terminable upon 30 days notice.

of Twister in connection with the Meeting of Twister's stockholders to consider
the Merger shall not, at the date the Proxy Statement (or any amendment thereof
or supplement thereto) is first mailed to stockholders, at the time of such
Meeting or at the Effective Time, contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or

circumstances under which they are made, not misleading.  The information

light of the circumstances under which they are made, not misleading.

                 (c)      Each party covenants and agrees that (i) if, at any
time prior to the Effective Time, any event relating to it or any of its
affiliates, officers or directors is discovered that should be set forth in an
amendment to the Registration Statement or Blue Sky Filings or a supplement to
the Proxy Statement, such party will promptly inform the other parties, and
such amendment or supplement will be promptly filed with the Commission and
appropriate state securities administrators and disseminated to the
stockholders of Twister and Tango, to the extent required by applicable Federal
and state securities laws, and (ii) documents which either party files or is
responsible for filing with the Commission and any regulatory agency in
connection with the Merger (including, without limitation, the Proxy Statement)
will comply as to form and content in all material respects with the provisions
of applicable law.  Notwithstanding the foregoing, no party makes any
representations or warranties with respect to any information that has been
supplied by the other party or by its auditors, attorneys, financial advisors,
other consultants or advisors specifically for use in the Registration
Statement, Blue Sky Filing, the Proxy Statement, or any other documents to be
filed with the Commission or any regulatory agency in connection with the
transactions contemplated hereby.

                 (d)      Twister hereby represents that its Board of Directors
has, (i) determined that the Merger is fair to and in the best interests of
Twister's stockholders, (ii) approved the Merger and (iii) resolved to and will
recommend in the Proxy Statement adoption of this Agreement and authorization

the Registration Statement shall become effective and addressed to Tango, of
the kind contemplated by the Statement of Auditing Standards with respect to

Time.  Prior to the Effective Time, except as set forth in Section 5.2 of the

         or consolidation with Twister or to cause the Registration Statement
         or the Proxy Statement to need to be amended by Tango or would
         otherwise materially delay or prevent the consummation of the

         million or, taking all such acquisitions in the aggregate, involving
         consideration not in excess of $10 million and which are of a nature
         so as not to require a merger or consolidation with Tango or to cause
         the Registration Statement or the Proxy Statement to need to be
         amended by Tango or would otherwise materially delay or prevent the

         payable by it to any of its employees, officers, consultants or
         directors (except in accordance with employment or consulting

                 (f)      Neither Tango nor any Tango Subsidiary shall take any
         action which would interfere with the parties' abilities to account
         for the merger as a "pooling of interests"; and

                 (g)      Neither Tango nor any Tango Subsidiary shall
         authorize or enter into any agreement to do any of the things
         described in clauses (a) through (f) of this Section 5.3.

         5.4     Access to Properties and Records.  Each party shall afford to
the other and their respective accountants, counsel and representatives
("Respective Representatives"), reasonable access during normal business hours
upon reasonable prior notice throughout the period prior to the Effective Time
to all of their respective properties (including, without limitation, books,
contracts, commitments and written records) and shall make reasonably available
during normal business hours upon reasonable prior notice their respective
officers and employees to answer fully and promptly questions put to them
thereby; provided, however, that no investigation pursuant to this Section 5.4
shall alter any representation or warranty of any party hereto or the
conditions to the obligations of the parties hereto.

         5.5     No Solicitation of Transactions.

                 (a)      None of Twister or any Twister Subsidiary shall, or
shall authorize or permit any of its officers, directors or employees or any
investment banker, financial advisor, attorney, accountant or other
representative or agent retained by Twister or any Twister Subsidiary to,
initiate or solicit or knowingly encourage (including by way of furnishing
non-public information), or take any other action to facilitate knowingly, any
inquiries or the making of any proposal that constitutes, or may reasonably be
expected to lead to, any Third Party Transaction (as such term is defined below
in this Section 5.5), or enter into or maintain or continue discussions or
negotiate with any person or entity in furtherance of such inquiries or to
obtain a Third Party Transaction.  Twister shall promptly notify Tango orally
and in writing of all relevant details relating to all proposals which it or
any Twister Subsidiary or any such officer, director, employee, investment
banker, financial advisor, attorney, accountant or other representative may
receive relating to any of such matters and, if such inquiry or proposal is in
writing, Twister shall forthwith deliver to Tango a copy of such inquiry or
proposal; provided, however, that nothing contained in this Section 5.5(a)
shall prohibit the Board of Directors of Twister from (i) furnishing
information to, or entering into discussions or negotiations or an agreement
with, any person or entity that makes an unsolicited offer of a Third Party
Transaction (a "Proposed Twister Transaction") if, and only to the extent that,
(A) the Board of Directors of Twister determines in its good faith judgment,
after consultation with independent legal counsel (which may include its
regularly engaged independent legal counsel) that such action is required for
the Board of Directors of Twister to comply with its fiduciary duties to
stockholders under applicable law, (B) in making the determination referenced
in Clause (A) above, the Board of Directors of Twister shall have determined in
good faith, after consultation with its financial advisors, that the Proposed
Twister Transaction would result in a transaction more favorable to Twister's
stockholders than the transaction contemplated by this Agreement (any such
Proposed Twister Transaction, as contemplated by clauses (A) through (C)

of this paragraph, referred to herein as a "Superior Twister Proposal") and (C)
prior to furnishing such information to, or entering into discussions or
negotiations with, such person or entity, Twister (x) provides written notice
to Tango to the effect that it is furnishing information to, or entering into
discussions or negotiations with, such person or entity and (y) receives from
such person or entity an executed confidentiality agreement in reasonably
customary form on terms not more favorable to such person or entity than the
terms contained in the Confidentiality Agreement (as hereinafter defined); (ii)
complying with Rule 14e-2 promulgated under the Exchange Act with regard to a
tender or exchange offer not made in violation of this Section 5.5(a) or (iii)
failing to make or withdrawing or modifying its recommendation referred to in
Section 5.1(d) if there exists a Third Party Transaction that the Board of
Directors of Twister determines, in its good faith judgment, is a Superior
Twister Proposal.

                 (b)      None of Tango or any Tango Subsidiary shall, or shall
authorize or permit any of its officers, directors or employees or any
investment banker, financial advisor, attorney, accountant or other
representative or agent retained by Tango or any Tango Subsidiary to, initiate
or solicit or knowingly encourage (including by way of furnishing non-public
information), or take any other action to facilitate knowingly, any inquiries
or the making of any proposal that constitutes, or may reasonably be expected
to lead to, any Third Party Transaction, or enter into or maintain or continue
discussions or negotiate with any person or entity in furtherance of such
inquiries or to obtain a Third Party Transaction.  Tango shall promptly notify
Twister orally and in writing of all relevant details relating to all proposals
which it or any Tango Subsidiary or any such officer, director, employee,
investment banker, financial advisor, attorney, accountant or other
representative may receive relating to any of such matters and, if such inquiry
or proposal is in writing, Tango shall forthwith deliver to Twister a copy of
such inquiry or proposal; provided, however, that nothing contained in this
Section 5.5(b) shall prohibit the Board of Directors of Tango from (i)
furnishing information to, or entering into discussions or negotiations or an
agreement with, any person or entity that makes an unsolicited offer of a Third
Party Transaction (a "Proposed Tango Transaction") if, and only to the extent
that, (A) the Board of Directors of Tango determines in its good faith
judgment, after consultation with independent legal counsel (which may include
its regularly engaged independent legal counsel) that such action is required
for the Board of Directors of Tango to comply with its fiduciary duties to
stockholders under applicable law, (B) in making the determination referenced
in Clause (A) above, the Board of Directors of Tango shall have determined in
good faith, after consultation with its financial advisors, that the Proposed
Tango Transaction would result in a transaction more favorable to Tango's
stockholders than the transaction contemplated by this Agreement (any such
Proposed Tango Transaction, as contemplated by clauses (A) through (C) of this
paragraph referred to herein as a "Superior Tango Proposal") and (C) prior to
furnishing such information to, or entering into discussions or negotiations
with, such person or entity, Tango (x) provides written notice to Twister to
the effect that it is furnishing information to, or entering into discussions
or negotiations with, such person or entity and (y) receives from such person
or entity an executed confidentiality agreement in reasonably customary form on
terms not more favorable to such person or entity than the terms contained in
the Confidentiality Agreement; (ii) complying with Rule 14e-2 promulgated under
the Exchange Act with regard to a tender or exchange offer not made in







                                      -39-

violation of this Section 5.5(b) or (iii) failing to make or withdrawing or
modifying its recommendation referred to in Section 5.1(d) if there exists a
Third Party Transaction that the Board of Directors of Tango determines, in its
good faith judgment, is a Superior Tango Proposal.

                 (c)      For purposes of this Agreement, "Third Party
Transaction" shall mean with respect to a party hereto any of the following
(other than transactions between Tango, Merger Sub and Twister contemplated
hereby): (i) any merger, consolidation, share exchange, business combination,
or other similar transaction involving such party; (ii) any sale, exchange,
transfer or other disposition of 20% or more of the assets of such party and
its Subsidiaries, taken as a whole, in a single transaction or series of
transactions; (iii) any sale of or tender offer or exchange offer for 20% or
more of the outstanding shares of capital stock of such party or the filing of
a registration statement under the Securities Act in connection therewith; (iv)
any person acquiring beneficial ownership or the right to acquire beneficial
ownership of, or any "group" (as such term is defined under Section 13(d) of
the Exchange Act and the rules and regulations promulgated thereunder) having
been formed for the purpose of effecting a Third Party Transaction referred to
in Sections 5.5(c)(i), (ii) or (iii) which beneficially owns or has the right
to acquire beneficial ownership of, 20% or more of the then outstanding shares
of capital stock of such party; or (v) any public announcement by such party of
a proposal, plan or intention to do any of the foregoing or any agreement to
engage in any of the foregoing with respect to such party.

         5.6     Employee Benefit Plans.  Except as otherwise provided in this
Agreement, the Twister employee benefit plans listed on the Twister Disclosure
Schedule which are in effect at the date of this Agreement shall remain in
effect for at least one year following the Effective Time.  Tango and Twister
shall cooperate in coordinating their respective benefit plans, and any Twister
employee benefit plan may be terminated after the Effective Time, but solely to
the extent that benefits are provided to the employees of Twister under one or
more employee benefits plans of Tango or any Tango Subsidiary ("Tango Plans")
which are least comparable to those provided under the employee benefit plans
or arrangements then provided under the Tango Plans and are not less beneficial
than the benefits provided to the employees of Twister under the employee
benefit plans or arrangements of Twister as of the Closing Date.  For all
purposes of determining eligibility and any and all entitlements under any
Tango Plan, service performed by employees of Twister prior to the Closing Date
shall be credited.

         5.7     Treatment of Options and Debentures.

                 (a)      Each Twister Stock Option issued pursuant to
Twister's 1995 Stock Option Plan, as amended (the "Twister Option Plan") or
issued other than pursuant to the Twister Option Plan set forth in the Twister
Disclosure Schedule, whether or not vested or exercisable, shall be assumed by
Tango and shall constitute an option to acquire, on the same terms and
conditions as were applicable under such assumed Twister Stock Option, a number
of shares of Tango Common Stock equal to the product of the Exchange Ratio and
the number of shares of Twister Common Stock subject to such Twister Stock
Option, at a price per share equal to the







                                      -40-
<PAGE>   46

aggregate exercise price for the shares of Twister Common Stock subject to such
Twister Stock Option divided by the number of full shares of Tango Common Stock
deemed to be purchasable pursuant to such Twister Stock Option; provided,
however, that (i) subject to the provisions of clause (ii) below, the shares of
Tango Common Stock that may be purchased upon exercise of such Twister Stock
Option shall not include any fractional shares and, upon the last such exercise
of such Twister Stock Option, a cash payment shall be made for any fractional
shares based upon the per share average of the highest and lowest sale price of
the Tango Common Stock as reported on the AMEX on the date of such exercise,
and (ii) in the case of any Twister Stock Option to which Section 421 of the
Code applies by reason of its qualification under Section 422 or Section 423 of
the Code ("Qualified Stock Options"), the option price, the number of shares
purchasable pursuant to such Twister Stock Option and the terms and conditions
of exercise of such Twister Stock Option shall be determined in order to comply
with Section 424 of the Code; provided, further that all Twister Stock Options
shall become vested and exercisable in full as of the Effective Time.  As soon
as practicable after the Effective Time, Tango shall deliver to holders of
Twister Stock Options appropriate option agreements representing the right to
acquire shares of Tango Common Stock on the same terms and conditions as
contained in the outstanding Twister Stock Options (subject to any adjustments
required by the preceding sentence), upon surrender of the outstanding Twister
Stock Options.  Notwithstanding anything herein which may be construed to the
contrary, each holder of a Twister Stock Option may elect, in accordance with
the change of control provision under the Twister Option Plan or in such
holder's stock option agreement that applies with respect to the Merger, to
receive a cash payment upon the cancellation or surrender of all or a portion
of such Twister Stock Option (as adjusted in accordance with this Section
5.7(a)), in an amount determined pursuant to such change of control provision.
Tango shall comply with the terms of the Twister Option Plan and the terms of
the Twister Stock Options issued other than pursuant to the Twister Option Plan
as they apply to the Twister Stock Options assumed as set forth above,
including, but not limited to, any other provisions regarding changes of
control that may apply with respect to the Merger.

                 (b)      Tango shall take all corporate action necessary to
reserve for issuance a sufficient number of shares of Tango Common Stock for
delivery upon exercise of the Twister Stock Options assumed in accordance with
this Section 5.7.  Tango shall file a registration statement on Form S-8 (or
any successor form) or another appropriate form, effective as of the Effective
Time, with respect to shares of Tango Common Stock subject to such Twister
Stock Options and shall use all reasonable efforts to maintain the
effectiveness of such registration statement or registration statements (and
maintain the current status of the prospectus or prospectuses contained
therein) for so long as such Twister Stock Options remain outstanding.  With
respect to those individuals who subsequent to the Merger will be subject to
the reporting requirements under Section 16(a) of the Exchange Act, Tango shall
administer the Twister Option Plan and the Twister Stock Options assumed
pursuant to this Section 5.7 in a manner that complies with Rule 16b-3
promulgated under the Exchange Act.

                 (c)      The Twister Debentures issued pursuant to the
Indenture dated as of May 23, 1996 (the "Twister Indenture") shall be assumed
by Tango at the Effective Time by Tango's







                                      -41-
<PAGE>   47

execution and delivery of a supplemental indenture as contemplated by the
Twister Indenture (the "Supplemental Indenture").  To the extent required by
the Twister Indenture, such Supplemental Indenture shall provide that holders
of the Twister Debentures have the right to convert, on the same terms and
conditions as were applicable immediately prior to the Merger, the principal
amount of any Twister Debentures into Tango Common Stock at a conversion price
(the "New Conversion Price") equal to the quotient of the conversion price in
effect for the Twister Debentures immediately prior to the Merger divided by
the Exchange Ratio.  Promptly following the Closing, Tango shall prepare and
file a registration statement on Form S-3 or another appropriate form with the
Commission to permit the sale under the Securities Act of the Twister
Debentures and the shares of Tango Common Stock issuable upon conversion
thereof, and Tango shall assume and satisfy the obligations of Twister arising
out of those certain Registration Rights Agreements dated as of May 17, 1996 by
and between Twister and the purchasers of the Twister Debentures.

                 (d)      Upon the execution of the Supplemental Indenture,
Tango shall take all corporate action necessary to reserve for issuance a
sufficient number of shares of Tango Common Stock for issuance and delivery
upon conversion of the Twister Debentures assumed in accordance with this
Section 5.7.

         5.8     Indemnification.

                 (a)  From and after the Effective Time, Tango shall indemnify,
defend and hold harmless to the fullest extent permitted under Delaware law
each person who is now, or has been at any time prior to the date hereof, an
officer or director of Twister (individually, an "Indemnified Party" and
collectively, the "Indemnified Parties"), against all losses, claims, damages,
liabilities, costs or expenses (including attorneys' fees), judgments, fines,
penalties and amounts paid in settlement of or otherwise in connection with any
claim, action, suit, proceeding or investigation (a "Claim") arising out of or
pertaining to acts or omissions, or alleged acts or omissions, by them in their
capacities as such occurring at or prior to the Effective Time (including,
without limitation, the transactions contemplated by this Agreement and the
Option Agreement).  In the event of any such Claim, Tango shall pay expenses in
advance of the final disposition of any such action or proceeding to each
Indemnified Party to the fullest extent permitted under the DGCL, upon receipt
from the Indemnified Party to whom expenses are advanced of the undertaking to
repay such advances contemplated by Section 145(e) of the DGCL.

                 (b)  Tango shall cause the Surviving Corporation to keep in
effect provisions in its Articles of Incorporation and Bylaws with respect to
indemnification and director and officer exculpation from liability identical
to such provisions contained in the Articles of Incorporation and Bylaws of
Twister on the date hereof, which provisions shall not be amended, repealed or
otherwise modified for a period of six years from the Effective Time in any
manner that would adversely affect the rights thereunder of individuals who at
any time prior to the Effective Time were directors or officers of Twister in
respect of actions or omissions at or prior to the Effective Time (including,
without limitation, the transactions contemplated by this Agreement







                                      -42-
<PAGE>   48

and the Cross Option Agreement, except as required by applicable law or except
to make changes permitted by law that would not materially diminish the
Indemnified Parties' right of indemnification.

                 (c)  For a period of six years after the Effective Time, Tango
shall cause to be maintained in effect the current officers' and directors'
liability insurance maintained by Twister (provided that Tango may substitute
therefor policies of at least the same coverage and amounts containing terms
and conditions which are no less advantageous than such existing insurance)
with respect to Claims arising from facts or events which occurred prior to the
Effective Time; provided, however, that Tango shall not be required in order to
maintain or procure such coverage to pay an annual premium in excess of two and
one-half times the current annual premium paid by Twister for its existing
coverage (the "Cap"); and provided, further, that if existing coverage cannot
be maintained or equivalent coverage cannot be obtained, or can be obtained
only by paying an annual premium in excess of the Cap, Tango shall only be
required to obtain as much coverage as can be obtained by paying an annual
premium equal to the Cap.

                 (d)  This Section 5.8 shall survive the closing of all of the
transactions contemplated hereby, is intended to benefit the officers and
employees of Twister and of the Twister Subsidiaries at the Effective Time and
each of the Indemnified Parties and their respective heirs and personal
representatives (each of which shall be entitled to enforce this Section 5.8
against Tango and the Surviving Corporation, as the case may be, as a
third-party beneficiary of this Agreement), and shall be binding on all
successors and assigns of Tango and the Surviving Corporation.

         5.9     Confidentiality.  The Amended and Restated Confidentiality
Agreement, dated even herewith (the "Confidentiality Agreement") between
Twister and Tango (a copy of which is attached hereto as Exhibit B) is hereby
affirmed by Tango and Twister and the terms thereof are herewith incorporated
herein by reference and shall continue in full force and effect until the
Effective Time shall have occurred, and if this Agreement is terminated or if
the Effective Time shall not have occurred for any reason whatsoever, the
Confidentiality Agreement shall thereafter remain in full force and effect in
accordance with its terms; provided, however, to the extent there are any
provisions in the Confidentiality Agreement inconsistent with the terms of this
Agreement, the terms of this Agreement shall control.

         5.10    Reasonable Best Efforts.  Subject to the terms and conditions
herein provided, the parties hereto shall:  (i) promptly make their respective
filings, and thereafter make any other required submissions, with respect to
this Agreement and the Merger required under (A) the Securities Act (in the
case of Tango) and the Exchange Act and the rules and regulations thereunder,
and any other applicable Federal or state securities laws, (B) the HSR Act and
(C) any other applicable Laws; (ii) use all reasonable efforts to cooperate
with one another in (A) determining which filings are required to be made prior
to the Effective Time with, and which consents, approvals, permits or
authorizations ("Third Party Consents") are required to be obtained prior to
the Effective Time from Governmental Entities or other third parties in
connection with the execution and delivery of this Agreement and the
consummation of the







                                      -43-
<PAGE>   49

transactions contemplated hereby and (B) timely making all such filings and
timely seeking all such Third Party Consents; and (iii) use all reasonable
efforts to take, or cause to be taken, all other action and do, or cause to be
done, all other things necessary, proper or appropriate to consummate and make
effective the transactions contemplated by this Agreement.  If, at any time
after the Effective Time, any further action is necessary or desirable to carry
out the purpose of this Agreement, the proper officers and directors of the
parties hereto shall take all such necessary action.  Each of the parties
hereto shall promptly give (or cause their respective subsidiaries to give) any
notices regarding the Merger, this Agreement or the transactions contemplated
hereby or thereby to third parties required under applicable Law or by any
contract, license, lease or other agreement to which it or any of its
subsidiaries is bound, and use, and cause its Subsidiaries to use, all
reasonable efforts to obtain any Third Party Consents required under any such
contract, license, lease or other agreement in connection with the consummation
of the Merger or the other transactions contemplated by this Agreement.  No
party hereto shall (i) take any action for the purpose of delaying, impairing
or impeding the receipt of any Third Party Consent, or the making of any
required filing or registration, (ii) take any action that could reasonably
have the effect of preventing Tango and Twister from accounting for the Merger
as a "pooling of interests" or (iii) subject to compliance with mandatory
disclosure requirements under applicable securities laws, take any action (or
fail to take any action) that could reasonably be expected to have an adverse
effect on the price of the Tango Common Stock.  Each party hereto shall use all
reasonable efforts to overturn or vacate any Law or Order (hereinafter defined)
(whether temporary, preliminary or permanent) enacted, issued, promulgated,
enforced or entered by any Governmental Entity or Federal or state court of
competent jurisdiction which is in effect and has effect of making the Merger
illegal or otherwise prohibiting consummation of the transactions contemplated
by this Agreement.

         5.11    Certification of Stockholder Vote.  At or prior to the Closing
of the transactions contemplated by this Agreement, Twister and Tango shall
deliver to each other a certificate of their respective Secretary setting forth
the number of shares of Twister Common Stock or Tango Common Stock, as the case
may be, voted in favor of adoption of this Agreement and consummation of the
Merger and the number of shares of Twister Common Stock or Tango Common Stock
voted against adoption of this Agreement and consummation of the Merger.

         5.12    Affiliate Agreements.

                 (a) Not fewer than 45 days prior to the Effective Time,
Twister shall deliver to Tango a list of names and addresses of each person who
was, in Twister's reasonable judgment, at the record date for the Twister
Meeting, an "affiliate" of Twister within the meaning of Rule 145 promulgated
under the Securities Act or applicable Commission accounting releases with
respect to "pooling of interests" accounting treatment (each a "Pooling
Affiliate").  Twister shall provide Tango such information and documents as
Tango shall reasonably request for purposes of reviewing such list.  Twister
shall use all reasonable efforts to deliver or cause to be delivered to Tango,
prior to the Effective Time, an affiliate agreement substantially in the form
attached hereto as Exhibit C-1 (each, a "Twister Affiliate Agreement"),
executed by each of the Pooling Affiliates of Twister identified in the
above-referenced list.







                                      -44-
<PAGE>   50


                 (b)  Tango shall use all reasonable efforts to obtain or cause
to be obtained, prior to the Effective Time, an affiliate agreement in
substantially the form attached hereto as Exhibit C-2 (each, a "Tango Affiliate
Agreement"), executed by each person who was, in Tango's reasonable judgment,
at the record date for the Tango Meeting, a Pooling Affiliate of Tango.

         5.13    Listing Application.  Tango shall promptly prepare and submit
to the AMEX a listing application covering the shares of Tango Common Stock
issuable in the Merger, and shall use its best efforts to obtain, prior to the
Effective Time, approval for the listing of such Tango Common Stock, subject to
official notice of issuance.

         5.14    Supplemental Disclosure Schedules.  Each of Tango and Twister
shall supplement their respective Disclosure Schedules delivered in connection
with this Agreement as of the Effective Time to the extent necessary to reflect
matters permitted by, or consented to by, the other party under this Agreement.
In addition, from time to time prior to the Effective Time, each of Tango and
Twister will promptly deliver to the other party such amended or supplemental
Disclosure Schedules as may be necessary to make the Schedules accurate and
complete in all material respects as of the Effective Time; provided, however,
that no such disclosure shall have any effect for the purpose of determining
the satisfaction of the conditions set forth in Article VI of this Agreement.

         5.15    No Action.  Except as contemplated by this Agreement, no party
hereto will, nor will either such party permit any of its Subsidiaries to, take

unable or unwilling to serve, such individual or individuals shall be replaced
by an individual or individuals designated by the Board of Directors of Tango.

                 (b)      Following the Effective Time and continuing through

Directors or their successors) and any nominee selected to fill a director
position occupied by any of the foregoing individuals (the "Twister Directors")
shall be nominated on behalf of the Tango Board of Directors, filled or
selected by a majority vote of the remaining Twister Directors and approved by
the Board of Directors of Tango, such approval not to be unreasonably withheld.

                 (c)      At the Effective Time, the Board of Directors of
Tango shall take all actions necessary to create an Executive Committee
("Executive Committee") to be comprised of Messrs. Petty, Lasky and Buchanan,
which committee shall have authority, acting by unanimous vote of all Executive
Committee members, to (i) approve development, acquisition and financing
transactions, without the separate approval of the Board of Directors of Tango,
up to levels approved by the Board of Directors of Tango in authorizing such
committee; (ii) review and formulate recommendations on matters to be submitted
to the Board of Directors of Tango; (iii) approve and manage the consolidation
of the operations of the Surviving Corporation and its Subsidiaries and Tango
and the Tango Subsidiaries; and (iv) have such additional responsibilities and
functions as are delegated from time to time by the Board of Directors of
Tango.

                 (d)      Effective at or immediately prior to the Effective
Time, the Board of Directors of Tango shall (i) take all actions necessary to

agreement in substantially the form attached hereto as Exhibit C-3 (the
"Executive Employment Agreement"); and (ii) take all action necessary to cause
Tango to execute and deliver to the persons listed on Schedule 5.17(d) hereto

persons listed on Schedule 5.17(d) hereto.

                 (e)      It is the intent of Tango and Twister that the
Surviving Corporation shall continue to operate as a separate and distinct
business unit and as a wholly-owned subsidiary of Tango with its principal
executive offices located at 543 S. Webb Road, Wichita, Kansas; provided,
however, such manner of operation shall be at the pleasure of the Executive
Committee which shall be delegated the responsibility of developing and
implementing measures to achieve coordination and integration of the Surviving
Corporation with and into Tango and, as such, shall have responsibility for
determining all matters relevant thereto.

                 (f)      At the Tango Meeting, as part of the approval of the
Merger, the Stockholders of Tango shall adopt the amendments to its Bylaws set

<PAGE>   52

attached hereto (the "Tango Bylaws Amendments"), which amendments are intended
to address the matters described in Section 5.17(b) and (c) of this Agreement
and which may only be amended, modified or repealed in accordance with their
terms.

                 (g)      At the Effective Time, Tango shall adopt the Stay

         5.18    Cross Option Agreement.  Simultaneously with the execution of
this Agreement, Tango and Twister have executed and delivered the Cross Option
Agreement in the form attached hereto as Exhibit D (the "Cross Option
Agreement").

         5.19    Plan of Reorganization.  This Agreement is intended to
constitute a "plan of reorganization" within the meaning of Section 1.368-2(g)
of the income tax regulations promulgated under the Code.  From and after the
date of this Agreement, each party hereto shall use all reasonable efforts to
cause the Merger to qualify, and shall not, without the prior written consent
of the other parties hereto, knowingly take any actions or cause any actions to
be taken which could reasonably be expected to prevent the Merger from
qualifying as a reorganization under the provisions of Section 368 of the Code.
In the event that the Merger shall fail to qualify as a reorganization under
the provisions of Section 368 of the Code, then the parties hereto agree to
negotiate in good faith to restructure the Merger in order that it shall
qualify as a tax-free transaction under the Code.  Following the Effective
Time, and consistent with any such consent, neither the Surviving Corporation
nor Tango nor any of their respective affiliates knowingly and voluntarily
shall take any action or cause any action to be taken which could reasonably be
expected to cause the Merger to fail to qualify as a reorganization under
Section 368 of the Code.

         5.20    Compliance by Merger Sub.  Tango shall take all action
necessary to cause Merger Sub to perform its obligations hereunder (including,
but not limited to, consummation of the Merger) and to otherwise comply with
the terms hereof.

         5.21    Change Corporate Name.  Tango and Twister agree to jointly
consider changing the corporate name of Tango after the Effective Time to a
name that, in the judgment of Tango and Twister, better reflects the resulting
business of Tango after the Merger and Tango's long-range strategic plans.

         Entity, which, in either case, would require either party to take any
         action or do anything in connection with the foregoing which would
         compel Tango to dispose of all or a material portion of the business
         or assets of Tango and the Tango Subsidiaries, taken as a whole, or of

6.1(b) shall not have been obtained at the Twister Meeting or at any
adjournment thereof, or (iv) a court of competent jurisdiction or Governmental
Entity shall have issued an order, decree or ruling or taken any other action
permanently restraining, enjoining or otherwise prohibiting the transactions
contemplated by this Agreement (an "Order") and such Order shall have become
final and non-appealable; provided, that the party seeking to terminate this
Agreement pursuant to this clause (iv) must have used all reasonable efforts to
remove such Order; provided further, in the case of a termination pursuant to
clause (i) above, that the terminating party shall not have breached in any
material respect its obligations under this Agreement in any manner that
proximately caused the occurrence of the failure referred to in said clause.

                 (c)      Termination by Tango.  This Agreement may be
terminated and the Merger may be abandoned at any time prior to the Effective
Time, before or after the adoption and approval by the stockholders of Tango
referred to in Section 6.1(b), by action of the Board of Directors of Tango if
(i) a Superior Tango Proposal for a Third Party Transaction involving Tango has
been made or received and such Board determines, in the exercise of its good
faith judgment (based on the advice of independent legal counsel) that such
termination is required for such Board to comply with its fiduciary duties to
the Tango stockholders; (ii) there has been a breach (provided that such breach
would have or would be reasonably likely to have a Material Adverse Effect on
Twister) of any representation, warranty, covenant or agreement on the part of
Twister set forth in this Agreement, or if any representation or warranty of
Twister shall have become untrue (provided that such untruth would have or
would be reasonably likely to have a Material Adverse Effect on Twister), in
either case such that the conditions in Section 6.3(a) or Section 6.3(b) would
not be satisfied (a "Terminating Twister Breach"); provided that, if such
Terminating Twister Breach is curable by Twister through the exercise of its
reasonable efforts and for so long as Twister continues to exercise such
reasonable efforts, Tango may not terminate this Agreement under this Section
7.1(c)(ii); (iii) following the receipt of a proposal of a Third Party
Transaction by Twister (including a Superior Twister Proposal), the Board of
Directors of Twister shall have altered its determination to recommend that the
stockholders of Twister approve this Agreement and the transactions
contemplated hereby; or (iv) following the receipt of a proposal for a Third
Party Transaction by Twister (including a Superior Twister Proposal), Twister
shall have failed to proceed to hold the Twister Meeting of its stockholders as
contemplated by Section 5.1, provided Tango gives Twister 24 hours' prior
written notice of its election to terminate under this clause (iv).

                 (d)      Termination by Twister.  This Agreement may be
terminated and the Merger may be abandoned at any time prior to the Effective
Time, before or after the adoption and approval by the stockholders of Twister
referred to in Section 6.1(b) by action of the Board of Directors of Twister if
(i) a Superior Twister Proposal for a Third Party Transaction involving Twister
has been made or received and such Board determines, in the exercise of its
good faith judgment (based on the advice of independent legal counsel) that
such termination is required for such Board to comply with its fiduciary duties
to the Twister stockholders; (ii) there has been a breach (provided that such
breach would have or would be reasonably likely to have







                                      -53-

a Material Adverse Effect on Tango) of any representation, warranty, covenant
or agreement on the part of Tango set forth in this Agreement, or if any
representation or warranty of Tango shall have become untrue (provided that
such untruth would have or would be reasonably likely to have a Material
Adverse Effect on Tango), in either case such that the conditions in Section
6.2(a) or Section 6.2(b) would not be satisfied (a "Terminating Tango Breach");
provided that, if such Terminating Tango Breach is curable by Tango through the
exercise of its reasonable efforts and for so long as Tango continues to
exercise such reasonable efforts, Twister may not terminate this Agreement
under this Section 7.1(d)(ii); (iii) following the receipt of a proposal of a
Third Party Transaction by Tango (including a Superior Tango Proposal), the
Board of Directors of Tango shall have altered its determination to recommend
that the stockholders of Tango approve this Agreement and the transactions
contemplated hereby; or (iv) following the receipt of a proposal for a Third
Party Transaction by Tango (including a Superior Tango Proposal), Tango shall
have failed to proceed to hold the Tango Meeting of its stockholders as
contemplated by Section 5.1, provided Twister gives Tango 24 hours' prior
written notice of its election to terminate under this clause (iv).

         7.2     Effects of Termination.

                 (a)      If (A) Tango terminates this Agreement pursuant to
clause (i) of Section 7.1(c), (B) Twister terminates this Agreement pursuant to
clause (iii) or (iv) of Section 7.1(d) following receipt by Tango of a proposal
for a Third Party Transaction (including a Superior Tango Proposal), or (C)
either Twister or Tango terminates this Agreement pursuant to clause (i) or
(ii) of Section 7.1(b) and prior to any Tango Meeting a proposal for a Third
Party Transaction (including a Superior Tango Proposal) was received by Tango
and such Third Party Transaction (or any revised transaction based upon such
proposal for a Third Party Transaction) is consummated (including, in the case
of a tender offer, acceptance of shares upon the expiration of the tender
offer) within one year after such termination, then, within two business days
of such termination in the case of clauses (A) and (B) or within two business
days of such consummation in the case of clause (C), Tango (or the successor
thereto) shall pay Twister by wire transfer in immediately available funds a
fee of $8 million; provided, however, that for purposes of this Section 7.2(a),
Third Party Transaction shall refer only to those transactions described in
Section 5.5(c)(i), (ii) and (iii) of this Agreement.

                 (b)      If (A) Twister terminates this Agreement pursuant to
clause (i) of Section 7.1(d), (B) Tango terminates this Agreement pursuant to
clause (iii) or (iv) of Section 7.1(c) following receipt by Twister of a
proposal for a Third Party Transaction (including a Superior Twister Proposal),
or (C) either Tango or Twister terminates this Agreement pursuant to clause (i)
or (iii) of Section 7.1(b) provided that prior to any Twister Meeting a
proposal for a Third Party Transaction (including a Superior Twister Proposal)
was received by Twister and such Third Party Transaction (or any revised
transaction based upon such proposal for a Third Party Transaction) is
consummated (including, in the case of a tender offer, acceptance of shares
upon the expiration of the tender offer) within one year after such
termination, then, within two business days of such termination in the case of
clauses (A) and (B) or within two business days of such consummation in the
case of clause (C), Twister (or the successor thereto) shall pay







                                      -54-

Tango by wire transfer in immediately available funds a fee of $8 million;
provided, however, that for purposes of this Section 7.2(b), Third Party
Transaction shall refer only to those transactions described in Section
5.5(c)(i), (ii) and (iii) of this Agreement.

                 (c)      Except as provided in this Section 7.2 or Section 8.3
or Section 8.4, in the event of the termination of this Agreement pursuant to
Section 7.1, this Agreement shall be void, there shall be no liability on the
part of the parties or any of their respective officers or directors to the
other and all rights and obligations of any party hereto shall cease; provided,
however, that nothing herein shall relieve any party from liability for the
wilful breach of any of its representations, warranties, covenants or
agreements set forth in this Agreement, or from any obligation under the
Confidentiality Agreement; provided, however, if either party has received the
$8 million fee contemplated by Section 7.2(a) or (b), the party receiving such
fee shall not assert or pursue in any manner, directly or indirectly, any claim
or cause of action (other than pursuant to the Cross Option Agreement) against
the party paying such fee or any of its officers or directors based in whole or
in part upon its or their receipt, consideration, recommendation or approval of
a proposal for a Third Party Transaction or the exercise of the right of the
party paying such fee to terminate this Agreement under clause (i) of Section
7.1(c) or clause (i) of Section 7.1(d), as the case may be.


                                  ARTICLE VIII
                                 MISCELLANEOUS

         8.1     Amendment.  Subject to the applicable provisions of state law,
this Agreement may be amended by the parties hereto solely by action taken by
their respective Boards of Directors at any time prior to the Effective Time;
provided, however, that after the approval of the Merger by a party's
stockholders, no amendment may be made which would reduce the amount or change
the type of consideration into which each Twister Share shall be converted
pursuant hereto.  This Agreement may not be amended except by an instrument in
writing signed on behalf of each of the parties hereto.

         8.2     Waiver.  At any time prior to the Effective Time, the parties
hereto, by action taken by their respective Boards of Directors, may (i) extend
the time for the performance of any of the obligations or other acts of the
other parties hereto, (ii) waive any inaccuracies in the representations and
warranties of the other party contained herein or in any documents delivered
pursuant hereto, and (iii) waive compliance by the other party with any of the
agreements or conditions herein.  Any agreement on the part of a party hereto
to any such extension or waiver shall be valid only if set forth in an
instrument in writing signed on behalf of such party.  No waiver by either
party of any default with respect to any provision, condition or requirement
hereof shall be deemed to be a waiver of any other provision, condition or
requirement hereof; nor shall any delay or omission of either party to exercise
any right hereunder in any manner impair the exercise of any such right
accruing to it thereunder.

         8.3     Survival.  All representations, warranties and agreements
contained in this Agreement or in any instrument delivered pursuant to this
Agreement shall terminate and be extinguished at the Effective Time or the
earlier date of termination of this Agreement pursuant to Section 7.1, as the
case may be, except that the agreements set forth in Article I and Article II
and in Sections 5.6, 5.7, 5.8, 5.17, 8.3 and 8.4 will survive the Effective
Time indefinitely and those set forth in Sections 5.9, 7.2 and Article VIII
will survive the termination of this Agreement indefinitely.

         8.4     Expenses and Fees.  Subject to Section 7.2, whether or not the
Merger is consummated, all costs and expenses incurred by the parties hereto in
connection with this Agreement and the transactions contemplated hereby shall
be paid by the party incurring such expenses except as expressly provided
herein and except that (i) the filing fee in connection with the HSR Act
filing, (ii) the filing fee in connection with the filing of the Registration
Statement or Proxy Statement with the Commission and (iii) the expenses
incurred in connection with printing and mailing the Registration Statement and
the Proxy Statement, shall be shared equally by Tango and Twister; provided,
however that if the Merger is consummated, Tango may, at its option, pay
Twister's expenses.

         8.5     Notices.  All notices and other communications given or made
pursuant hereto shall be in writing and shall be given (and shall be deemed to

such press release or make any such public statement (other than statements in
response to inquiries received with respect to this Agreement or the

without the prior consent of the other party, issue such press release or make
such public statement as may be required by Law or any listing agreement with a
national securities exchange to which Twister or Tango is a party if it has
used reasonable efforts to consult with the other party and to obtain such
party's consent but has been unable to do so in a timely manner.

         8.8     Certain Definitions.  For purposes of this Agreement, the
term:

through the ownership of stock or as trustee or executor, by contract or credit
arrangement or otherwise;

                 (d)      "knowledge" or "known" shall mean, with respect to
any matter in question, if an executive officer of Tango or Twister, as the

         8.9     Entire Agreement.  This Agreement (together with the

implied, is intended to confer upon any other person any rights, benefits or
remedies of any nature whatsoever under or by reason of this Agreement.

         8.11    Counterparts.  This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement and
each of which shall be deemed an original.

         8.12    Invalidity; Severability.  In the event that any provision of
this Agreement shall be deemed contrary to law or public policy or invalid or
unenforceable in any respect by a court of competent jurisdiction, the

and limited solely to the extent necessary to render the same valid and
enforceable.  Upon such determination that any term or other provision is
invalid, illegal, or incapable of being enforced, the parties hereto shall
negotiate in







                                      -58-

good faith to modify this Agreement so as to effect the original intent of the
parties as closely as possible in an acceptable manner to the end that
transactions contemplated hereby are fulfilled to the extent possible.

         8.13    Governing Law.  The validity and interpretation of this
Agreement shall be governed by, and construed in accordance with, the laws of
the State of Delaware, without reference to the conflict of laws principles

                                AMENDMENT NO. 1
                                       TO
                                RIGHTS AGREEMENT



         This AMENDMENT NO. 1 TO THE RIGHTS AGREEMENT (this "Amendment"), is
made and entered into this 30th day of July, 1997, by and between Sterling
House Corporation, a Kansas corporation (the "Company"), and ChaseMellon
Shareholder Services, L.L.C., a New Jersey limited liability company (the
"Rights Agent"). This Amendment amends that certain Rights Agreement, dated
June 25, 1997 (the "Rights Agreement"), between the Company and the Rights
Agent.

         1. Section 1 of the Rights Agreement is hereby amended by deleting
paragraph (a) thereof and replacing it in its entirety with the following:

                  (a) "Acquiring Person" shall mean any Person who or which,
         together with all Affiliates and Associates of such Person, shall be
         the Beneficial Owner of 20% or more of the shares of Common Stock then
         outstanding, but shall not include (i) the Company, (ii) any
         Subsidiary of the Company, (iii) any employee benefit plan of the
         Company or any Subsidiary of the Company or (iv) any Person or entity
         organized, appointed or established by the Company for or pursuant to
         the terms of any such plan. Notwithstanding the foregoing, no Person
         shall become an "Acquiring Person" solely as the result of an
         acquisition of Common Stock by the Company which, by reducing the
         number of shares outstanding, increases the proportionate number of
         shares beneficially owned by a Person to 20% or more of the Common
         Stock of the Company then outstanding as determined above; provided,
         however, that if a Person becomes the Beneficial Owner of 20% or more
         of the Common Stock then outstanding (as determined above) solely by
         reason of purchases of Common Stock by the Company, after such
         purchases by the Company, becomes the Beneficial Owner of any
         additional shares of Common Stock by any means whatsoever, then such
         Person shall be deemed to be an "Acquiring Person." Notwithstanding
         the foregoing, if the Board of Directors of the Company determines in
         good faith that a Person who would otherwise be an "Acquiring Person,"
         as defined pursuant to the foregoing provisions of this paragraph (a),
         has become such inadvertently, and such Person divests as promptly as
         practicable a sufficient number of shares of Common Stock so that such
         Person would no longer be an "Acquiring Person,"




<PAGE>   2


         as defined pursuant to the foregoing provisions of this paragraph (a),
         then such Person shall not be deemed an "Acquiring Person" for any
         purposes of this Agreement. Notwithstanding the foregoing, if a Person
         becomes the Beneficial Owner of 20% or more of the Common Stock then
         outstanding solely as a result of such Person's entering into an
         agreement, arrangement or understanding whereby such Person obtains
         the right to vote such security and prior to the time such agreement,
         arrangement or understanding is entered into the Board of Directors of
         the Company has approved either (i) a "business combination" (as such
         term is defined in Section 17-12,100(c) of the Kansas General
         Corporation Code) to which such Person is a party or (ii) such
         agreement, arrangement or understanding with such Person then such
         Person shall not be deemed to be an "Acquiring Person."

         2. The amendment to the Rights Agreement set forth herein shall be
effective as of July 30, 1997. Except as modified by this Amendment, the Rights
Agreement shall remain in full force and effect.

         3. This Amendment may be executed by facsimile and 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.

         IN WITNESS WHEREOF, the Company has caused this Amendment to be duly
executed by its duly authorized officer, and the Rights Agent has caused this
Agreement to be duly executed by its authorized officer, and the parties have
caused this Amendment to be delivered, all on the day and year first written
above.

FOR IMMEDIATE RELEASE:




ALTERNATIVE LIVING SERVICES, INC. AND STERLING HOUSE CORPORATION AGREE TO MERGE

             FORMING THE NATION'S LARGEST ASSISTED LIVING COMPANY



Brookfield, Wisconsin (July 31, 1997) - Alternative Living Services, Inc.
("ALS") (AMEX:ALI) and Sterling House Corporation ("Sterling House")
(AMEX:SGH), announced today that they have entered into a definitive merger
agreement under which Alternative Living Services, Inc. will issue 1.1 shares
of its common stock in exchange for each outstanding share of Sterling House
common stock.  The announcement was made jointly by William Lasky, President
and Chief Executive Officer of ALS, and Timothy Buchanan, Chairman of the Board
and Chief Executive Officer of Sterling House.


This strategic business combination will create the nation's largest assisted
living company providing healthcare services both in terms of total revenues
and residences in operation, as well as the largest operator of residences for
individuals with Alzheimer's disease and other memory impairments.



                                    (more)

The combined company will have 178 residences in operation in 19 states with an
aggregate capacity

<PAGE>   2
to accommodate approximately 8,000 residents.  The combined Company will have
66 residences under construction and 81 in development.  Current annualized
revenues of the combined Company are in excess of $115 million.

The boards of directors of ALS and Sterling House have each unanimously
approved the merger agreement.  The transaction is valued at approximately
$170 million, including the assumption of all outstanding Sterling House
indebtedness.

After the merger, there will be approximately 18.5 million shares of ALS common
stock outstanding with a value, based on current market prices, of
approximately $400 million.  Holders of approximately 46% of the outstanding
shares of Sterling House have agreed to vote their shares in favor of the
merger, and each of ALS and Sterling House have granted to the other an option 
to purchase 19.9% of the outstanding common stock of the other under certain 
circumstances.

This business combination is intended to qualify as a tax-free reorganization
and is expected to be accounted for as a pooling of interests.  The parties
contemplate closing the merger in the fourth quarter of 1997.  Closing of the
merger is subject to the satisfaction of customary conditions, including the
receipt of stockholder and regulatory approvals.  Schroder & Co. Inc. is acting
as financial advisor to Sterling House.  McDonald & Company Securities, Inc. is
acting as financial advisor to ALS.

William Petty will continue to serve as Chairman, William Lasky as Chief
Executive Officer, and Timothy Buchannan will join as President, of the
combined Company.  Steven Vick will continue to serve as President of Sterling
House during the initial transition period and will then serve as Chief
Operating Officer of the combined Company.

"We believe this strategic merger establishes a strong national platform which
will serve to enhance shareholder value by bringing together two highly
experienced management teams," Bill Lasky and Tim Buchanan stated.  "These
teams share a common vision to provide choice for our country's frail elderly
with high quality healthcare services and attractive residential options,"
they said.  "In addition, we believe the combined Company will derive
significant economic benefits including certain operating synergies and
increased access to traditional and capital financing sources," Lasky and
Buchanan said.

NEITHER THIS CROSS OPTION AGREEMENT NOR THE SECURITIES ISSUABLE UPON EXERCISE
HEREOF HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE

OPTION AGREEMENT AND THE SECURITIES ISSUABLE UPON EXERCISE HEREOF, IF ANY, MAY
NOT BE SOLD OR TRANSFERRED EXCEPT UPON SUCH REGISTRATION OR UPON DELIVERY TO
TWISTER OR TANGO, AS THE CASE MAY BE, OF AN OPINION OF COUNSEL OR OTHER EVIDENCE
SATISFACTORY TO TWISTER OR TANGO, AS THE CASE MAY BE, THAT REGISTRATION IS NOT

                              W I T N E S S E T H:

         WHEREAS, concurrently with the execution of this Agreement, Tango,
Merger Sub and Twister are entering into an Agreement and Plan of Merger of even
date herewith (the "Merger Agreement"; capitalized terms used but not defined
herein shall have the same meaning assigned to such terms in the Merger
Agreement), pursuant to which Tango proposes to combine with Twister by means of
a merger (the "Merger") of Merger Sub with and into Twister in which (a) each
issued and outstanding share of common stock, no par value, of Twister (the

par value, of Merger Sub shall be converted into one hundred (100) shares of
fully paid and nonassessable shares of common stock, no par value, of the
Surviving Corporation; and (c) each option to purchase Twister Common Stock
outstanding as of the Effective Time shall be assumed by Tango as provided in
Section 5.7 of the Merger Agreement; and

         WHEREAS, as a condition to the willingness of the parties to enter into
the Merger Agreement and incur expenses and expend time and effort in connection
with the Merger Agreement and transactions contemplated thereby, Tango has
required that Twister agree, and Twister has agreed, among other things, to
grant to Tango the Twister Option (as hereinafter defined), and Twister has
required that Tango agree, and Tango has agreed, among other things, to grant to
Twister the Tango Option (as hereinafter defined), in each case in accordance

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements contained herein and in the Merger Agreement and
intending to be legally bound hereby, the parties hereto hereby agree as
follows:


<PAGE>   2





                                    ARTICLE I
                            THE TWISTER STOCK OPTION

         1.1  Grant of Twister Stock Option. Twister hereby grants to Tango an
irrevocable option (the "Twister Stock Option") to purchase, subject to the
terms hereof 1,003,344 fully paid and non-assessable shares (the "Twister Option
Shares") of Twister Common Stock at a purchase price of $18.25 per Twister
Option Share (the "Twister Stock Purchase Price") in the manner set forth in
Sections 1.2, 1.3 and 1.4 hereof; provided, however, that in no event shall the
number of shares of Twister Common Stock for which the Twister Stock Option is
exercisable exceed 19.9% of the number of shares of Twister Common Stock
outstanding before the exercise of the Twister Stock Option. The number of
shares of Twister Common Stock that may be received upon the exercise of the
Twister Stock Option and the Twister Stock Purchase Price are subject to
adjustment as set forth herein.

         1.2  Exercise of Twister Stock Option.

              (a)  The Twister Stock Option may be exercised by Tango, in
whole or in part, at any time or from time to time after the Merger Agreement
becomes terminable or is terminated by Tango or Twister under circumstances
which could entitle Tango to termination fees under Section 7.2(b) of the Merger
Agreement (regardless of whether the Merger Agreement is actually terminated or
whether there occurs a closing of any Third Party Transaction), any such event
by which the Twister Stock Option becomes exercisable being referred to herein
as a "Tango Triggering Event." In the event Tango wishes to exercise all or any
part of the Twister Stock Option, Tango shall deliver to Twister a written
notice (a "Tango Exercise Notice," with the date of the Twister Exercise Notice
being hereafter called the "Twister Notice Date") notifying Twister of its
exercise of the Twister Stock Option and specifying the number of Twister Option
Shares to be purchased. The closing of such exercise of the Twister Stock Option
(a "Twister Option Closing") shall occur at a place, and on a date (not earlier
than three nor later than 30 business days from the Twister Notice Date) and at
a time designated by Tango in the Tango Exercise Notice. The Twister Stock
Option shall terminate upon the earlier of: (i) the Effective Time; (ii) the
termination of the Merger Agreement in accordance with its terms (other than
upon or during the continuance of a Tango Triggering Event); or (iii) 365 days
following any termination of the Merger Agreement upon or during the
continuation of a Tango Triggering Event (or, if, at the expiration of such 365
day period the Twister Stock Option cannot be exercised by reason of any
applicable judgment, decree, order, law or regulation, ten business days after
such impediment to exercise shall have been removed or shall have become final
and not subject to appeal, but in no event under this clause (iii) later than
June 30, 1998). Notwithstanding the foregoing, the Twister Stock Option may not
be exercised if Tango is in (i) breach of any of its representations or
warranties in this Agreement or in the Merger Agreement which are qualified with
respect to a Material Adverse Effect on Tango or materiality, (ii) material
breach of any of its representations or warranties

                                       -2-


<PAGE>   3



in this Agreement or the Merger Agreement that are not so qualified, or (iii)
material breach of any of its covenants or agreements contained in this
Agreement or in the Merger Agreement.

              (b)  Upon receipt of a Tango Exercise Notice, Twister shall be
obligated to deliver to Tango a certificate or certificates evidencing the
Twister Option Shares, in accordance with the terms of this Agreement, on the
later of (i) the date specified in the Tango Exercise Notice or (ii) the first
business day on which the conditions specified in Section 1.3 shall be
satisfied.

         1.3  Conditions to Delivery of the Twister Option Shares. The right of
Tango to exercise the Twister Stock Option and the obligation of Twister to
deliver the Twister Option Shares upon any exercise of the Twister Stock Option
is subject to the following conditions:

              (a)  Such delivery would not in any material respect violate,
or otherwise cause the material violation of, any material law, including,
without limitation, the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended, and the rules and regulations thereunder (the "HSR Act") applicable to
such exercise of the Twister Stock Option and the delivery of the Twister Option
Shares; and

              (b)  There shall be no preliminary or permanent injunction or
other order by any court of competent jurisdiction preventing or prohibiting
such exercise of the Twister Stock Option or the delivery of the Twister Option
Shares in respect of such exercise (and no action or proceeding shall have been
commenced or threatened for purposes of obtaining the same).

         1.4  Closings. At any Twister Option Closing, (i) Twister will deliver
to Tango a certificate or certificates evidencing the number of Twister Option
Shares being purchased in the denominations specified in the Tango Exercise
Notice, and, if the Twister Stock Option has been exercised in part, a new
Twister Stock Option evidencing the right of Tango to purchase the balance of
the Twister Option Shares; and (ii) Tango will pay to Twister the aggregate
purchase price for the Twister Option Shares to be purchased by Tango. All
payments made by Tango to Twister pursuant to this Section 1.4 shall be made, at
the option of Tango, either by wire transfer of immediately available funds or
by delivery to Twister of a certified or bank cashier's check or checks payable
to or on the order of Twister, in either case in the amount of the Twister Stock
Purchase Price multiplied by the number of shares to be purchased.

         1.5  Adjustments Upon Share Issuances, Changes in Capitalization, etc.
In the event of any change in Twister Common Stock or in the number of
outstanding shares of Twister Common Stock by reason of a stock dividend,
split-up, recapitalization, combination, exchange of shares or similar
transaction or any other change in the corporate or capital structure of Twister
(including, without limitation, the declaration or payment of an extraordinary
dividend or cash, securities or other property), the type and number of shares
or securities to be issued by Twister upon exercise of the Twister Stock Option
shall be adjusted appropriately, and proper provision shall be made in the
agreements governing such transaction, so that Tango shall

                                       -3-


<PAGE>   4



receive upon exercise of the Twister Stock Option the number, and class of
shares and voting power represented thereby or other securities or property that
Tango would have received in respect of Twister Common Stock if the Twister
Stock Option had been exercised immediately prior to such event, or the record
date therefor, as applicable, and elected to the fullest extent it would have
been permitted to elect, to receive such securities, cash or other property.

         1.6  Legends. The certificate or certificates evidencing the Twister
Option Shares acquired upon exercise of the Twister Option Shares shall bear a
legend in substantially the following form:

         THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD OR TRANSFERRED,
         ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER
         SUCH ACT OR UNLESS THE ISSUER HAS RECEIVED AN OPINION OF COUNSEL OR
         OTHER EVIDENCE, SATISFACTORY TO THE ISSUER AND ITS COUNSEL, THAT SUCH
         REGISTRATION IS NOT REQUIRED.

         It is understood and agreed that the above legend will be removed by
delivery of substitute certificate(s) without such legend if the holder shall
have delivered to Twister a copy of a letter from the staff of the Commission,
or an opinion of counsel in form and substance reasonably satisfactory to
Twister and its counsel, to the effect that such legend is not required for
purposes of the Securities Act.

                                   ARTICLE II
                             THE TANGO STOCK OPTION

         2.1  Grant of Tango Stock Option. Tango hereby grants to Twister an

hereof 2,586,303 fully paid and non-assessable shares (the "Tango Option
Shares") of Tango Common Stock at a purchase price of $21.625 per Tango Option
Share (the "Tango Stock Purchase Price") in the manner set forth in Sections
2.2, 2.3 and 2.4 hereof; provided, however, that in no event shall the number of
shares of Tango Common Stock for which the Tango Stock Option is exercisable
exceed 19.9% of the number of shares of Tango Common Stock outstanding
immediately before the exercise of the Tango Stock Option. The number of shares
of Tango Common Stock that may be received upon the exercise of the Tango Stock

         2.2  Exercise of Tango Stock Option.

<PAGE>   5


terminated by Twister or Tango under circumstances which could entitle Twister
to termination fees under Section 7.2(a) of the Merger Agreement (regardless of
whether the Merger Agreement is actually terminated or whether there occurs a
closing of any Third Party Transaction), any such event by which the Tango Stock
Option becomes exercisable being referred to herein as a "Twister Triggering
Event." In the event Twister wishes to exercise all or any part of the Tango
Stock Option, Twister shall deliver to Tango a written notice (a "Twister
Exercise Notice," with the date of the Tango Exercise notice being hereafter
called the "Tango Notice Date") notifying Tango of its exercise of the Tango

The closing of such exercise of the Tango Stock Option (a "Tango Option
Closing") shall occur at a place, and on a date (not earlier than three nor
later than 30 business days from the Tango Notice Date) and at a time designated
by Twister in the Twister Exercise Notice. The Tango Stock Option shall
terminate upon the earlier of: (i) the Effective Time; (ii) the termination of
the Merger Agreement in accordance with its terms (other than upon or during the
continuance of a Twister Triggering Event); or (iii) 365 days following any
termination of the Merger Agreement upon or during the continuation of a Twister
Triggering Event (or, if, at the expiration of such 365 day period the Tango
Stock Option cannot be exercised by reason of any applicable judgment, decree,
order, law or regulation, ten business days after such impediment to exercise
shall have been removed or shall have become final and not subject to appeal,
but in no event under this clause (iii) later than June 30, 1998).
Notwithstanding the foregoing, the Tango Stock Option may not be exercised if
Twister is in (i) breach of any of its representations or warranties in this
Agreement or in the Merger Agreement which are qualified with respect to a
Material Adverse Effect on Twister or materiality, (ii) material breach of any
of its representations or warranties in this Agreement or the Merger Agreement
that are not so qualified, or (iii) material breach of any of its covenants or
agreements contained in this Agreement or in the Merger Agreement.

business day on which the conditions specified in Section 1.3 shall be
satisfied.

         2.3  Conditions to Delivery of the Tango Option Shares. The right of
Twister to exercise the Tango Stock Option and the obligation of Tango to
deliver the Tango Option Shares upon any exercise of the Tango Stock Option is
subject to the following conditions:

              (a)  Such delivery would not in any material respect violate,
or otherwise cause the material violation of, any material law, including,
without limitation, the HSR Act applicable to such exercise of the Tango Stock
Option and the delivery of the Tango Option Shares; and

              (b)  There shall be no preliminary or permanent injunction or 
other order by any court of competent jurisdiction preventing or prohibiting
such exercise of the Tango Stock

                                       -5-


<PAGE>   6



Option or the delivery of the Tango Option Shares in respect of such exercise

         2.4  Closings. At any Tango Option Closing, (i) Tango will deliver to
Twister a certificate or certificates evidencing the number of Tango Option
Shares being purchased in the denominations specified in the Twister Exercise
Notice, and, if the Tango Stock Option has been exercised in part, a new Tango
Stock Option evidencing the right of Twister to purchase the balance of the
Tango Option Shares; and (ii) Twister will pay to Tango the aggregate purchase
price for the Tango Option Shares to be purchased by Twister. All payments made
by Twister to Tango pursuant to this Section 2.4 shall be made, at the option of
Twister, either by wire transfer of immediately available funds, or by delivery
to Tango of a certified or bank cashier's check or checks payable to or on the

         OTHER EVIDENCE, SATISFACTORY TO THE ISSUER AND ITS COUNSEL, THAT SUCH

                                   ARTICLE III
                    REPRESENTATIONS AND WARRANTIES OF TWISTER

         Twister hereby represents and warrants to each of Tango as follows:

         3.1  Authority Relative to This Agreement. Twister has all necessary
power and authority to execute and deliver this Agreement, to perform its
obligations hereunder and to consummate the transactions contemplated hereby.
The execution and delivery of this Agreement by Twister and the consummation by
Twister of the transactions contemplated hereby have been duly and validly
authorized by the Board of Directors of Twister, and no other corporate
proceedings on the part of Twister are necessary to authorize this Agreement or
to consummate such transactions. This Agreement has been duly and validly
executed and delivered by Twister and, assuming the due authorization, execution
and delivery by Tango, constitutes a legal, valid and binding obligation of
Twister, enforceable against Twister in accordance with its terms.

         3.2  Authority to Issue Shares. Twister has taken all necessary
corporate action to authorize and reserve and permit it to issue, and at all
times from the date hereof until the Twister Stock Option shall no longer be
exercisable, shall have reserved, all the Twister Option Shares issuable
pursuant to this Agreement, and Twister will take all necessary corporate action
to authorize and reserve and permit it to issue all additional shares of Twister
Common Stock or other securities which may be issued pursuant to Section 1.5,
all of which, upon their issuance and delivery in accordance with the terms of
this Agreement, shall be duly authorized, validly issued, fully paid and
nonassessable, shall be delivered free and clear of all security interests,
liens, claims, pledges, options, rights of first refusal, agreements,
limitations on Tango's voting rights, charges and other encumbrances of any
nature whatsoever (other than this Agreement) and shall not be subject to any
preemptive rights.

         3.3  No Violation. The execution and delivery of this Agreement by
Twister do not, the performance of this Agreement by Twister will not, (i)
violate or conflict with any provision of any Laws in effect on the date of this
Agreement and applicable to Twister or any Twister Subsidiary or by which any of
their respective properties or assets is bound or subject, (ii) require Twister
or any Twister Subsidiary to obtain any consent, waiver, approval, license or
authorization or permit of, or make any filing with, or notification to, any
Governmental Entities, based on laws, rules, regulations and other requirements
of Governmental Entities in effect and of the date of this Agreement (other than
(a) the filing of a Pre-Merger Notification Report under the HSR Act and the
expiration of the applicable waiting period, (b) filings or authorizations
required in connection or in compliance with the provisions of the Exchange Act,
the Securities Act, the KGCC, the Bylaws of the AMEX or the "takeover" or "blue
sky" laws

                                       -7-


<PAGE>   8



of various states or (c) any other filings and approvals expressly contemplated
by this Agreement), (iii) require the consent, waiver, approval, license or
authorization of any person (other than Governmental Entities), (iv) violate,
conflict with or result in a breach of or the acceleration of any obligation
under, or constitute a default (or an event which with notice or the lapse of
time or both would become a default) under, or give to others any right of, or
result in any, termination, amendment, acceleration or cancellation of, or loss
of any benefit or creation of a right of first refusal, or require any payment
under, or result in the creation of a lien or other encumbrance on any of the
properties or assets of Twister or any Twister Subsidiary pursuant to or under
any provision of any indenture, mortgage, note, bond, lien, lease, license,
agreement, contract, order, judgment, ordinance, Twister Permit (as defined
below) or other instrument or obligation to which Twister or Twister Subsidiary
is a party or by which Twister or any Twister Subsidiary or any of their
respective properties is bound or subject to, or (v) conflict with or violate
the Articles of Incorporation or Bylaws, or the equivalent organizational
documents, in each case as amended or restated, of Twister or any of the Twister
Subsidiaries, except for any such conflicts or violations described in clause
(i) or breaches, defaults, events, rights of termination, amendment,
acceleration or cancellation, payment obligations or liens or encumbrances
described in clause (iv) that would not have a Material Adverse Effect on
Twister and except where the failure to obtain such consents, approvals,
authorizations or permits, or to make such filings or notifications would not,
either individually or in the aggregate, prevent Twister from performing any of
its obligations under this Agreement and would not have a Material Adverse
Effect on Twister. Neither Twister nor any of its affiliates or associates (as
each such term is defined in Section 203 of the DGCL) is, prior to the date
hereof, an "interested stockholder" (as such term is defined in Section 203 of
the DGCL) of Tango.

         3.4  Investment Intent. Twister is acquiring the Tango Option, and the
Tango Option Shares issuable upon any exercise of the Tango Option, for
investment for its own account and not with a view to, or for resale in
connection with, any distribution within the meaning of the Securities Act.

                                   ARTICLE IV
                              COVENANTS OF TWISTER

         Twister hereby covenants and agrees as follows:

         4.1  Listing; Other Action. (a) If Twister Common Stock or any other
securities to be acquired upon exercise of the Twister Option are then listed on
the AMEX, Twister, upon the request of Tango, shall, at its expense, promptly
file an application to list such shares or other securities on AMEX and will use
reasonable best efforts to obtain approval of such listing on the AMEX, subject
to notice of issuance, as promptly as practicable.

                                       -8-


<PAGE>   9



              (b)  Twister shall use its reasonable best efforts to take, or
cause to be taken, all appropriate action, and to do, or cause to be done, all
things necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the transactions contemplated hereunder,
including, without limitation, using its reasonable best efforts to obtain all
licenses, permits, consents, approvals, authorizations, qualifications and
orders of Governmental Entities. Without limiting the generality of the
foregoing, Twister shall, when required in order to effect the transactions
contemplated hereunder, make all filings and submissions under the HSR Act as
promptly as practicable.

         4.2  Registration. Upon the request of Tango at any time and from time
to time within two (2) years of the first Twister Option Closing, Twister agrees
(i) to effect, as promptly as practicable, up to two registrations under the
Securities Act covering any part or all (as may be requested by Tango) of the
securities that have been acquired by or are issuable to Tango upon exercise of
the Twister Stock Option, and to use its best efforts to qualify such Twister
Option Shares or other securities under any applicable state securities laws and
(ii) to include any part or all of the Twister Option Shares or such other
securities in any registration statement for common stock filed by Twister under
the Securities Act in which such inclusion is permitted under applicable rules
and regulations and to use its reasonable best efforts to keep each such
registration described in clause (i) effective for a period of not in excess of
six (6) months, unless, in the written opinion of counsel to Twister, addressed
to Tango and reasonably satisfactory in form and substance to Tango, such
registration is not required for the sale and distribution of such securities in
the manner contemplated by Tango. If the managing underwriter of a proposed
offering of securities by Twister shall advise Twister in writing that, in the
reasonable opinion of the managing underwriter, the distribution of the Twister
Option Shares requested by Tango to be included in a registration statement
concurrently with securities being registered for sale by Twister would
adversely affect the distribution of such securities by Twister, then Twister
shall, at its option, either (i) include such Twister Option Shares in the
registration statement, but Tango shall agree to delay the offering and sale for
such period of time as the managing underwriter may reasonably request (provided
that Tango may at any time withdraw its request to include the Twister Option
Shares in such offering) or (ii) include such portion of the Twister Option
Shares in the registration statement as the managing underwriter advises may be
included for sale simultaneously with sales by Twister. The registrations
effected under this Section 4.2 shall be effected at Twister's expense except
for underwriting commissions and discounts and the fees and disbursements of
Tango's counsel. With respect to a registration statement which has become
effective pursuant to this Agreement, if the Board of Directors of Twister shall
determine, in its good faith reasonable judgment, that it is necessary to
suspend the availability of such registration statement in light of the
existence of any undisclosed acquisition or financing activity or other
undisclosed material event, circumstance or condition involving Twister or any
subsidiary of Twister, the disclosure of which in any such case could reasonably
be expected to materially disadvantage Twister, and the existence of which would
render such registration statement inadequate as failing to include material
information, then Twister may cause the right of Tango to make dispositions of
Twister Option Shares pursuant to such registration statement to be suspended
for one or more periods

                                       -9-


<PAGE>   10



of time not exceeding 90 days in the aggregate as the Board of Directors of
Twister determines in its good faith reasonable judgment to be necessary. If
Twister determines to suspend the right of the holders pursuant to the
immediately preceding sentence, Twister shall deliver a notice to Tango which
indicates that such registration statement is no longer usable. Upon the receipt
of any such notice, Tango shall forthwith discontinue any sale of Twister Option
Shares pursuant to such registration statement and any use of the prospectus
contained therein. As soon as the circumstances which resulted in the delivery
of any such notice cease to exist, Twister shall promptly notify Tango of such
cessation, whereupon Tango may resume making dispositions of Twister Option
Shares pursuant to such registration statement. Tango shall provide all
information reasonably requested by Twister for inclusion in any registration
statement to be filed hereunder. In connection with any registration pursuant to
this Section 4.2, Twister and Tango shall provide each other and any underwriter
of the offering with customary representations, warranties, covenants,
indemnification and contribution.

         4.3  Distribution. Twister shall acquire the Tango Option Shares for
investment purposes only and not with a view to any distribution thereof in
violation of the Securities Act, and shall not sell any Tango Option Shares
purchased pursuant to this Agreement except in compliance with the Securities
Act.

                                    ARTICLE V

power and authority to execute and deliver this Agreement, to perform its

Agreement, and Tango will take all necessary corporate action to authorize and
reserve and permit it to issue all additional shares of Tango Common Stock or
other securities which may be issued pursuant to Section 2.5, all of which, upon
their issuance and delivery in accordance with the terms of this Agreement,

delivered free and clear of all security interests,

liens, claims, pledges, options, rights of first refusal, agreements,
limitations on Twister's voting rights, charges and other encumbrances of any

any Tango Subsidiary to obtain any consent, waiver, approval, license or
authorization or permit of, or make any filing with, or notification to, any
Governmental Entities, based on laws, rules, regulations and other requirements
of Governmental Entities in effect and of the date of this Agreement (other than
(a) the filing of a Pre-Merger Notification Report under the HSR Act and the
expiration of the applicable waiting period, (b) filings or authorizations
required in connection or in compliance with the provisions of the Exchange Act,
the Securities Act, the DGCL, the Bylaws of the AMEX or the "takeover" or "blue

contemplated by this Agreement), (iii) require the consent, waiver, approval,
license or authorization of any person (other than Governmental Entities), (iv)
violate, conflict with or result in a breach of or the acceleration of any
obligation under, or constitute a default (or an event which with notice or the
lapse of time or both would become a default) under, or give to others any right
of, or result in any, termination, amendment, acceleration or cancellation of,
or loss of any benefit or creation of a right of first refusal, or require any
payment under, or result in the creation of a lien or other encumbrance on any
of the properties or assets of Tango or any Tango Subsidiary pursuant to or
under any provision of any indenture, mortgage, note, bond, lien, lease,

Subsidiary is a party or by which Tango or any Tango Subsidiary or any of their

documents, in each case as amended or restated, of Tango or any of the Tango
Subsidiaries, except for any such conflicts or violations described in clause

acceleration or cancellation, payment obligations or liens or encumbrances
described in clause (iv) that would not have a Material Adverse Effect on Tango
and except where the failure to obtain such consents, approvals, authorizations
or permits, or to make such filings or notifications would not, either
individually or in the aggregate, prevent Tango from performing any of its
obligations under this Agreement and would not have a Material Adverse Effect on
Tango. Neither Tango nor any of its affiliates or associates (as each such term
is defined in Section 17-1297 of the KGCC) is, prior to the date hereof, an
"interested shareholder" (as such term is defined in Section 17-12,100 of the
KGCC) of Twister.

Twister Option Shares upon any exercise of the Twister Option, for investment
for its own account and not with a view to, or for resale in connection with,

                               COVENANTS OF TANGO

         Tango hereby covenants and agrees as follows:

         6.1  Listing; Other Action. (a) If Tango Common Stock or any other
securities to be acquired upon exercise of the Tango Option are then listed on
the AMEX, Tango, upon the request of Twister, shall, at its expense, promptly
file an application to list such shares or other securities on AMEX and will use
reasonable best efforts to obtain approval of such listing on the AMEX, subject
to notice of issuance, as promptly as practicable.

              (b)  Tango shall use its reasonable best efforts to take, or

effected under this Section 4.2 shall be effected at Tango's expense except for
underwriting commissions and discounts and the fees and disbursements of
Twister's counsel. With respect to a registration statement which has become

of Directors of Tango determines in its good faith reasonable judgment to be
necessary. If Tango determines to suspend the right of the holders pursuant to

         7.3  Entire Agreement. This Agreement constitutes the entire agreement
between the parties and supersedes all prior agreements and understandings, both

subject matter hereof.

law or otherwise.

                                      -14-

         7.5  Governing Law.  This Agreement, and all matters relating hereto, 
shall be governed by, and construed in accordance with the laws of the State of
Delaware without giving effect to the principles of the laws thereof.

         7.6  Injunctive Relief. The parties agree that in the event of a breach
of any provision of this Agreement irreparable damage would occur, the aggrieved
party would be without an adequate remedy at law and damages would be difficult
to determine. The parties therefore agree that in the event of a breach of any
provision of this Agreement, the aggrieved party may elect to institute and
prosecute proceedings in any court of competent jurisdiction to enforce specific
performance or to enjoin the continuing breach of such provision. By seeking or
obtaining such relief, the aggrieved party will not be precluded from seeking or
obtaining any other relief to which it may be entitled at law or in equity.

         7.7  Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original and all of which
together shall constitute one and the same document.

         7.8  Severability. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, such provision shall be
interpreted to be only so broad as is enforceable.

                          STOCKHOLDER VOTING AGREEMENT


         This STOCKHOLDER VOTING AGREEMENT (the "Agreement") is entered into on
July __, 1997, by and among the undersigned stockholder(s) (collectively, if
more than one, "Stockholder") of Tango, a Delaware corporation ("Tango"), and
Twister, a Kansas corporation ("Twister").

                              WITNESSETH:

         WHEREAS, concurrently with the execution of this Agreement, Twister,
Merger Sub and Tango are entering into an Agreement and Plan of Merger of even
date herewith (the "Merger Agreement") (capitalized terms used but not defined
herein shall have the same meaning assigned to such terms in the Merger
Agreement), pursuant to which Tango proposes to combine with Twister by means of
a merger (the "Merger") of Merger Sub with and into Twister in which (a) each
issued and outstanding share of common stock, no par value, of Twister (the
"Twister Common Stock"), other than shares of Twister Common Stock that are
owned by Twister as treasury stock, shall automatically be converted into the
right to receive 1.1 shares (the "Exchange Ratio") of the common stock, $.01 par
value, of Tango (the "Tango Common Stock"); (b) the issued and outstanding
shares of the common stock, $.01 par value, of Merger Sub shall be converted
into one hundred (100) shares of fully paid and nonassessable shares of common
stock, no par value, of the Surviving Corporation; and (c) each option to
purchase Twister Common Stock outstanding as of the Effective Time shall be
assumed by Twister as provided in Section 5.7 of the Merger Agreement;

         WHEREAS, Stockholder owns, as of the date hereof, the shares of Tango
Common Stock as set forth on Schedule A attached hereto (collectively, the
"Existing Shares," together with any shares of Tango Common Stock acquired after
the date hereof and prior to the termination hereof, hereinafter collectively
referred to as the "Shares"); and

         WHEREAS, Twister has entered into the Merger Agreement in reliance on
Stockholder's representations, warranties, covenants and agreements hereunder.

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements contained herein and intending to be legally bound
hereby, the parties hereto hereby agree as follows:

                                    ARTICLE I
                                      PROXY

         1.1 PROXY.

         (a) With respect to the Merger Agreement or any Third Party Transaction
for which approval of the stockholders of Tango is sought, and any transactions
contemplated thereby, Stockholder hereby irrevocably makes, constitutes and 
appoints Twister to act as Stockholder's true and lawful proxy and
attorney-in-fact in the name and on behalf of Stockholder, with full power to
appoint a substitute or substitutes. Stockholder further directs Twister, and
Twister hereby agrees, to vote all of the Shares which are entitled to vote at
any meeting of the shareholders of Tango (whether annual or special and whether
or not an adjourned meeting), or by written consent in the place and stead of
Stockholder in favor of the Merger as set forth in the Merger Agreement and
against any Third Party Transaction. By giving this proxy Stockholder hereby
revokes any other proxy granted by Stockholder at any time with respect to the
Shares and no subsequent proxies will be given with respect thereto by
Stockholder.

         (b) All power and authority hereby conferred is coupled with an
interest and is irrevocable, shall not be terminated by any act of Stockholder
or by operation of law, by lack of appropriate power of authority, or by the
occurrence of any other event or events and shall be binding upon all
beneficiaries, heirs at law, legatees, distributees, successors, assigns and
legal representatives of Stockholder. If after the execution of this Agreement,
Stockholder shall cease to have appropriate power or authority, or if any other
such event or events shall occur, Twister is nevertheless authorized and
directed to vote the Shares in accordance with the terms of this Agreement as if
such lack of appropriate power or authority or other event or events had not
occurred and regardless of notice thereof.

         (c) Stockholder agrees to use all good faith efforts to cause any
record owner of the Shares of which Stockholder is the beneficial owner to grant
to Twister a proxy of the same effect as that contained herein. Stockholder
shall perform such further acts and execute such further documents as may be
required to vest in Twister the sole power to vote the Shares in accordance
herewith during the term of the proxy granted herein.

         (d) The proxy granted herein shall expire on the date of termination of
this Agreement.

execution of this Agreement nor the consummation by Twister of the transactions
contemplated hereby will (i) require any consent or approval of or filing with

         6.2 ENTIRE AGREEMENT. This Agreement, together with the documents
expressly referred to herein, constitute the entire agreement among the parties.
hereto with respect to the subject matter contained herein and supersede all
prior agreements and understandings among the parties with respect to such
subject matter.

         6.3 ASSIGNS. This Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective successors, assigns and
personal representatives, but neither this Agreement nor any of the rights,
interests or obligations hereunder shall be assigned by any of the parties

         6.4 GOVERNING LAW. This Agreement, and all matters relating hereto,
shall be governed by, and construed in accordance with the laws of the State of
Delaware without giving effect to the principles of conflicts of laws thereof.

         6.5 COUNTERPARTS. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original and all of which
together shall constitute one and the same document.

         6.6 SEVERABILITY. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining 


                                      -5-
<PAGE>   6

terms and provisions of this Agreement or affecting the validity or
enforceability of any of the terms or provisions of this Agreement in any other
jurisdiction. If any provision of this Agreement is so broad as to be
unenforceable, such provision shall be interpreted to be only so broad as is
enforceable.

         6.7 FURTHER ASSURANCES. Each party hereto shall execute and deliver
such additional documents as may be necessary or desirable to consummate the
transactions contemplated by this Agreement.

         6.8 LEGAL EXPENSES. In the event any legal proceeding is commenced by
any party to this Agreement to enforce or recover damages for any breach of the
provisions hereof, the prevailing party in such legal proceeding shall be
entitled to recover in such legal proceeding from the losing party such
prevailing party's costs and expenses incurred in connection with such legal
proceedings, including reasonable attorney's fees.

         6.9 AMENDMENT AND MODIFICATION. This Agreement may be amended, modified
and supplemented only by a written document executed by Twister and Stockholder.

         6.10 SPECIFIC PERFORMANCE. The parties agree that in the event of a
breach of any provision of this Agreement, irreparable damage would occur, the
aggrieved party would be without an adequate remedy at law and damages would be
difficult to determine. The parties therefore agree that in the event of a
breach of any provision of this Agreement, the aggrieved party may elect to
institute and prosecute proceedings in any court of competent jurisdiction to
enforce specific performance or to enjoin the continuing breach of such
provision. By seeking or obtaining such relief, the aggrieved party will not be
precluded from seeking or obtaining any other relief to which it may be entitled
at law or in equity.

                        CERTAIN COVENANTS OF STOCKHOLDER

         5.1 CERTAIN COVENANTS OF STOCKHOLDER.

         (a) Except in accordance with the provisions of this Agreement,
Stockholder agrees, while this Agreement is in effect, not to, directly or
indirectly:

             (i)   Sell, transfer, pledge, encumber, assign or otherwise
dispose of, or enter into any contract, option or other arrangement or
understanding with respect to the sale, transfer, pledge, encumbrance,
assignment or other disposition of, any of the Shares unless the party to whom
such Shares are (or are to be) sold, pledged, assigned or otherwise transferred
shall have executed an acknowledgement and ratification of the grant of proxy
effected by this Agreement, in such form and substance as are reasonably
acceptable to Tango; or

             (ii)  Grant any proxy, deposit any Shares into a voting trust
or enter into a voting agreement with respect to any of the Shares.

         (b) Stockholder agrees, while this Agreement is in effect, to notify
Tango promptly of the number of any shares of Twister Common Stock acquired by
such Stockholder after the date hereof.

         (c) Until such time as this Agreement is terminated, Stockholder agrees
to take any actions as reasonably requested by Twister, within his, her or its
power as are necessary or appropriate to enable Twister to satisfy the
conditions precedent set forth in the Merger Agreement to Tango's obligations to
consummate the Merger, and to use his, her or its best efforts to cause Twister
to satisfy such conditions precedent.

                                   ARTICLE VI
                           CERTAIN COVENANTS OF TANGO

         6.1 CERTAIN COVENANTS OF TANGO. In the event that the shares of Tango
Common Stock received or to be received by the Stockholder in the Merger were
not or will not be registered under the Securities Act as contemplated by the
Merger Agreement or are or will be otherwise deemed to be "restricted
securities" (as such term is defined in Rule 144 promulgated under the
Securities Act) (each, a "Triggering Event"), then the Stockholder may request
Tango at any time after the Effective Time (i) to effect, as promptly as
practicable, a registration or registrations under the Securities Act, covering
that portion of the number of shares of Tango Common Stock that the Stockholder
receives in the Merger as he would otherwise be entitled



                                      -4-
<PAGE>   5

to sell pursuant to Rule 144 promulgated under the Securities Act within the
first twelve (12) months following the Effective Time in the event such shares
were registered in the manner contemplated by the Merger Agreement, taking into
account the period during which the Stockholder will otherwise be prohibited
from selling any shares of Tango Common Stock pursuant to Section 8 of the
Affiliate Agreement attached as Exhibit C-1 to the Merger Agreement (the
"Registered Shares"), (ii) to cause such registration to become effective not
later than the day on which Tango publishes the earnings release contemplated by
the penultimate paragraph of the Affiliate Agreement attached as Exhibit C-1 to
the Merger Agreement and to use its reasonable best efforts to keep each such
registration effective until the one year anniversary of the Effective Time (the
"Shelf Registration Statement") and (iii) to use its reasonable best efforts to
qualify such shares of Tango Common Stock under any applicable state securities
laws. The Stockholder, however, agrees not to sell under the Shelf Registration
Statement in any three month period more than that number of Registered Shares
that he would be permitted to sell under Rule 144 in the absence of the Shelf
Registration Statement (assuming that the Shares covered by the Shelf
Registration Statement were eligible for sale under Rule 144). All expenses
incident to the Shelf Registration Statement shall be borne by Tango, except
that the Stockholder shall pay any underwriting discounts, commissions or fees
attributable to the sale of any shares of Tango Common Stock registered thereby.
In connection with any registration pursuant to this Section 6.1, Tango and
Stockholder shall provide each other and any underwriter of the offering with
customary representations, warranties, covenants, indemnification and
contribution. In addition, in the event of a Triggering Event and, if Tango at
any time prior to the one year anniversary of the Effective Time proposes to
register for sale under the Securities Act any shares of Tango Common Stock held
by directors of Tango other than the Twister Directors, then Tango shall offer
to register the shares of Tango Common Stock held by the Stockholder on a pro
rata basis with all other shares of Tango Common Stock to be registered under
the Securities Act for the directors of Tango other than the Twister Directors.

expressly referred to herein, constitute the entire agreement among the parties
hereto with respect to the subject matter contained herein and supersede all
prior agreements and understandings among the parties with respect to such
subject matter.

         7.3 ASSIGNS. This Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective successors, assigns and
personal representatives, but neither this Agreement nor any of the rights,

hereto without the prior written consent of the other parties.

together shall constitute one and the same document.

         7.6 SEVERABILITY. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, such provision shall be

transactions contemplated by this Agreement.

         7.8 LEGAL EXPENSES. In the event any legal proceeding is commenced by

         7.9 AMENDMENT AND MODIFICATION. This Agreement may be amended, modified
and supplemented only by a written document executed by Tango, Merger Sub and
Stockholder.

         7.10 SPECIFIC PERFORMANCE. The parties agree that in the event of a
breach of any provision of this Agreement, irreparable damage would occur, the
aggrieved party would be without an adequate remedy at law and damages would be
difficult to determine. The parties therefore agree that in the event of a
breach of any provision of this Agreement, the aggrieved party may elect to
institute and prosecute proceedings in any court of competent jurisdiction to
enforce specific performance or to enjoin the continuing breach of such
provision. By seeking or obtaining such relief, the aggrieved party will not be
precluded from seeking or obtaining any other relief to which it may be entitled
at law or in equity.

         IN WITNESS WHEREOF, Tango and Merger Sub have caused this Agreement to
be executed by their duly authorized officers and Stockholder has executed this
Agreement, each as of the date set forth above.

                              EMPLOYMENT AGREEMENT

                  THIS AGREEMENT ("Agreement") is made and entered into this
30th day of July, 1997, by and between Steven L. Vick, a resident of the State
of Kansas ("Employee"), Sterling House Corporation, a Kansas corporation (the
"Company"), and Alternative Living Services, Inc., a Delaware corporation (the
"Tango").

                              W I T N E S S E T H:

                  WHEREAS, concurrent with the execution hereof, Tango, Tango
Merger Corporation, a Kansas corporation and a wholly owned subsidiary of Tango
("Merger Sub"), and the Company, have entered into that certain Agreement and
Plan of Merger, dated July 30, 1997 (the "Merger Agreement"), whereby Merger
Sub will be merged with and into the Company, with the Company as the surviving
corporation, and the Company shall become a wholly owned subsidiary of Tango
(the "Merger");

                  WHEREAS, the Employee has been an employee, officer,
director, and shareholder of the Company;

                  WHEREAS, after the Merger, the Company, as a wholly owned
subsidiary of Tango, will continue to carry on the business previously carried
on by the Company;

                  WHEREAS, the Company and Tango each desire to employ Employee
as a senior executive officer of the Company effective at the Effective Time
(as defined in the Merger Agreement);

                  WHEREAS, the Company and Tango, on the one hand, and
Employee, on the other hand, each desire to enter into this Agreement, pursuant
to which Employee will be employed by the Company and Tango on the terms and
conditions hereinafter set forth, and to make certain other agreements;

                  NOW, THEREFORE, in consideration of the premises and of the
promises and agreements hereinafter set forth, the parties hereto, intending to
be legally bound, do hereby agree as follows:

SECTION 1.  Employment.

         Subject to the terms and conditions hereof, the Company and Tango
hereby employ Employee, and Employee hereby accepts such employment. Employee
agrees that he will faithfully perform his duties hereunder and will devote his
full business time to the business and affairs of the Company and Tango.





<PAGE>   2



SECTION 2.  Titles; Location; Duties.

         2.1 Titles. Employee shall serve as the President of the Company, and
as such, Employee will report directly to the Board of Directors of the Company
from and after the Relocation Date (as hereinafter defined). Employee shall
also serve as the Chief Operating Officer of Tango, and as such, Employee will
report directly to the Chief Executive Officer and President of Tango.
Employee's duties are set forth in Section 2.3. At no time shall Employee be
requested to perform duties which are not commensurate with his status as the
President of the Company or, after the Relocation Date, as Chief Operating
Officer of Tango. Tango hereby agrees that, during the term hereof, Tango will
nominate Employee for election as a director of Tango and Employee hereby
consents to serve, without additional compensation, when elected, as a director
of Tango.

         2.2 Location. Employee's location of employment shall be at the
Company's principal executive offices in Wichita, Kansas; provided, however,
that Employee agrees to relocate his residence to Wisconsin and that the
location of his employment shall be at Tango's principal executive offices in
Brookfield, Wisconsin not later than the first anniversary of the Closing Date
(as defined in the Merger Agreement (the date on which Employee actually so
relocates being herein referred to as the "Relocation Date"); provided,
further, that Tango may not transfer Employee to any other location after the
Relocation Date without Employee's prior written consent unless the transfer
results from the relocation of Tango's principal executive offices and the
actual relocation thereto of other executive officers of Tango holding
positions and responsibilities comparable to those of Employee.

         2.3 Duties. Employee, as President of the Company, shall have the
duties customarily associated with that of a president, including, but not
limited to, overall management responsibility for the Company, as well as
responsibility for the coordination and integration of the business and

Closing Date. Commencing on the Relocation Date, Employee, as Chief Operating
Officer of Tango, also shall have the duties customarily associated with that
of a chief operating officer, including, but not limited to, general management
responsibility for the day-to-day business and operations of Tango and its
subsidiaries.

SECTION 3.  Term; Payments Upon Termination.

         3.1 Term. The employment of Employee hereunder shall commence on the

(the "Original Term") or (b) the occurrence of any of the following events:




                                       2

<PAGE>   3



              (i) the death or disability of Employee (disability meaning a
         physical illness or incapacity that prevents Employee totally and
         permanently from performing all of the substantial and material duties
         of his then current position of employment with the Company; provided,
         however, that a disability shall be considered to exist only if
         Employee is prevented for a period of three (3) consecutive months
         following the date such condition commenced and at the end of such
         three (3) month period he remained so prevented, or if, prior to the
         expiration of such three (3) month period, Employee's attending
         physician provides the Company and Tango with a written prognosis that
         the illness, injury or other incapacity that results in Employee's
         current disabled condition may be reasonably expected to prevent
         Employee from performing all of the substantial and material duties of
         his then current position of employment with the Company for a period
         of at least six (6) consecutive months;

             (ii) the mutual written agreement of the parties hereto
         terminate Employee's employment hereunder;

            (iii) the Company's and Tango's termination of Employee's
         employment hereunder for "cause." For the purposes of this Agreement,
         "cause" for termination of Employee's employment shall exist only (x)
         if Employee is convicted of, or pleads guilty to, any act of fraud,
         misappropriation or embezzlement, or any felony, (y) if Employee has
         engaged in conduct or activities materially damaging to the Company or
         Tango, monetarily or otherwise (it being understood, however, that
         neither conduct nor activities pursuant to Employee's exercise of his
         good faith business judgment nor unintentional physical damage to any
         property of the Company or Tango by Employee shall be a ground for
         such a determination by the Company and Tango) or (z) if Employee has
         willfully and continuously failed to substantially perform his duties
         hereunder (other than any such failure resulting from incapacity due
         to physical or mental illness), after a written demand for substantial
         performance is delivered to Employee that specifically identifies the
         manner in which the Company and Tango believe that Employee has not
         substantially performed those duties, and Employee has failed to
         resume substantial performance of such duties on a continuous basis
         within fourteen (14) days after receiving such demand. Termination for
         cause shall be made only upon the vote of not less than a majority of
         the Board of Directors of Tango then in office, after reasonable
         notice to Employee and an opportunity for Employee, together with
         counsel, to be heard before a duly called meeting of such Board; or

             (iv) the Employee's termination of his employment with
         the Company and Tango for "good reason" upon reasonable



                                      
                                      3

<PAGE>   4



         notice to the Company and Tango. For purposes of this Agreement, "good
         reason" shall exist if (x) the Company materially fails to comply with
         any of the provisions of this Agreement, other than isolated,
         insubstantial or inadvertent failures not occurring in bad faith and
         which are remedied by the Company promptly after receipt of notice
         thereof given by Employee, (y) the Company shall diminish Employee's
         title, duties, base salary or benefits, except, in the case of base
         salary or benefits, if such diminution is part of an overall
         diminution of base salary and benefits for all senior executive
         officers, or (z) any breach by the Company of its agreements set forth
         in Section 5.17 of the Merger Agreement.

             The Original Term hereof, and any renewal term, shall be 
automatically renewed for an additional one (1) year period unless either
Employee or the Company and Tango gives notice to the other party that it does
not wish to renew this Agreement at least ninety (90) days prior to the
expiration of such Original Term or renewal term, as the case may be.

         3.2 Payments Upon Termination.

         (a) If during the Original Term hereof, or any renewal term,
Employee's employment is terminated (i) by the Company and Tango without
"cause" or, (ii) by Employee for any "good reason," then the Company and Tango
shall pay to Employee the Employee's Base Salary at the rate in effect at the
time notice of termination is given, together with any applicable bonuses
(without pro-ration as provided in Section 4.2) and rights and benefits the
Employee may have under employee benefits plans and programs of the Company and
Tango in existence as of the date of such termination, all for the period (the
"Extended Period") equal to the greater of (x) the balance of the Original Term
or renewal term, as applicable, or (y) the twelve (12) month period following
the date of such termination.

         (b) If during the Original Term, or any renewal term, Employee's
employment is terminated as a result of the death or disability of Employee
(disability having the meaning set forth in Section 3.1(i) of this Agreement),
the Company and Tango shall continue to pay Employee (or his estate) his Base
Salary at the rate in effect on the date of death or the date disability is
conclusively determined, as applicable, together with any applicable bonuses
(without pro-ration as provided in Section 4.2) and rights and benefits the
Employee may have under employee benefits plans and programs of the Company and
Tango in existence as of the date of such termination, all for the twelve (12)
month period following the date of death or the date disability is conclusively
determined, as applicable.

<PAGE>   5



         (c) If during the Original Term, or any renewal term, Employee's
employment is terminated (i) by the Company and Tango for "cause" or (ii)
Employee for any reason other than "good reason," then the Company and Tango
shall pay Employee the Base Salary (as hereinafter defined) through the
effective date of termination at the rate in effect at the time notice of
termination is given, and the Company and Tango shall have no further
obligations to Employee under this Agreement subject to the rights and benefits
the Employee may have under employee benefits plans and programs of the Company
and Tango in existence as of the effective date of such termination, if any,
which shall be determined in accordance therewith.

         3.3 Payments Upon Change of Control. During the Original Term hereof,
or any renewal term, if there is a Change of Control (as hereinafter defined)
and any one of (i) the Employee's location of employment as set forth herein
changes, (ii) the Company takes any action which would entitle Employee to
terminate his employment for "good reason" pursuant to clauses (x), or (z) of
the definition thereof, or (iii) the Company and Tango shall diminish
Employee's title, duties, base salary or benefits (each of the events described
in the foregoing clauses (i), (ii) and (iii) being herein referred to as a
"Triggering Event"), then Employee may at his election, at any time within one
year after any such Triggering Event, terminate this Agreement (a "Voluntary
Termination"), and Employee shall be entitled to the following compensation, in
addition to the other compensation and bonuses provided for herein:

                  (a) in lieu of any further salary payments to Employee for
         periods subsequent to the date of Voluntary Termination, the Company
         and Tango shall pay as severance payment to Employee, no later than
         the fifth day following the date of Voluntary Termination, a lump-sum
         severance payment to Employee equal to 300% of Employee's annual base
         salary rate in effect as of the date of Voluntary Termination or, if
         greater, such rate as may be in effect immediately prior to the Change
         of Control. In addition, Employee shall be paid an amount equal to
         300% of his bonus for the calendar year immediately preceding the year
         in which such Voluntary Termination shall occur or, if greater, his
         bonus for the full calendar year preceding the year in which such
         Change of Control occurs; and

                  (b) the Company and Tango shall provide Employee with all
         employee benefits and programs of the Company which the Employee was

         For the purposes of this Agreement, "Change of Control" shall mean the
occurrence of any of the following events:

                  (i)   any "person" or "group" (as such terms are used under
Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as Amended
(the "Exchange Act"), whether or not such Sections are applicable) is or
becomes, whether by means of any issuance or direct or indirect transfer of
securities, merger, consolidation, liquidation, dissolution or otherwise, the
"beneficial owner" (as that term is used under Rules 13d-3 and 13d-5 under the
Exchange Act, whether or not such rules are applicable, except that a "person"
or "group" shall be deemed to have "beneficial ownership" of all shares that he
or it has the right to acquire, whether such right is exercisable immediately
or only after the passage of time or otherwise), directly or indirectly through
one or more intermediaries, of 35% or more of the total voting power
represented by all of the voting stock of Tango; or

                  (ii)  directly or indirectly, a transfer, sale, lease or other
disposition of all or substantially all of the assets of Tango and its
subsidiaries taken as a whole to any "person" or "group" (as such terms are
used un Sections 13(d) and 14(d) of the Exchange Act, whether or not such
sections are applicable), excluding any disposition to or among Tango and/or
one or more of its subsidiaries; or

                  (iii) any "person" or "group" (as such terms are used under
Sections 13(d) and 14(d) of the Exchange Act, whether or not such sections are
applicable) otherwise obtains the right or power (through any arrangement,
contract, proxy or other means) to elect or designate a majority of the members
of the Board of Directors of Tango then in office, without regard to whether
such right or power is exercised or invoked and without taking into account the
necessity of a special or annual stockholders meeting or the taking of other
procedural actions to exercise or invoke such right or power.

         Section 3.4. If pursuant to Section 3.2 or 3.3, Employee is entitled
to receive benefits under employee benefit plans subsequent to his termination
of employment and such benefits or programs cannot be made available following
termination of Employee in circumstances in which Employee is entitled thereto
hereunder, the Company and Tango shall pay Employee an amount in cash
sufficient to enable Employee to purchase such benefits or programs on his own
behalf. Employee shall retain all grants and awards issued to him under Tango's
stock incentive plans during any period subsequent to termination of Employee's
employment and during which Employee is entitled to receive salary or benefits
pursuant to Section 3.2 or Section 3.3.

SECTION 4.  Compensation.

         4.1 Base Salary. For the first twelve (12) months of the term of his
employment hereunder, Employee shall be paid a salary at the annual rate of Two
Hundred Twenty Five Thousand Dollars ($225,000), payable in equal installments
in accordance with the payroll payment practices from time to time adopted by
the Company, subject to required payroll withholding provisions. Thereafter,
the salary to be paid to the Employee shall be determined in the discretion of
the Board of Directors; provided, however, that in no event after the first
twelve (12) months of the term of his employment hereunder shall Employee's
annual rate of salary be less than Two Hundred Sixty Five Thousand Dollars
($265,000). (The annual salary to be paid to Employee under this Agreement is
hereinafter referred to as the "Base Salary".)

         4.2 Incentive Bonuses. As additional compensation hereunder, the
Company and Tango may, in the discretion of the Board of Directors of Tango,
pay Employee an annual bonus (the "Annual Bonus") for each fiscal year during
the term of Employee's employment hereunder. Subject to Section 3.2 hereof, if
Employee's employment hereunder is terminated pursuant to the terms of this
Agreement prior to the end of a calendar year, his Annual Bonus with respect to
that year shall be prorated for such portion of that year as he was employed by
the Company and Tango. The Employee shall be eligible to receive an Annual
Bonus of up to 35% of the Base Salary payable if Tango's earnings before
interest, taxes and depreciation are within 10% of such earnings targeted in
the applicable annual business plan as approved by the Board of Directors of
Tango. Any such discretionary or pro rated bonus shall be due and payable upon
the submission and verification of Tango's annual financial statements for the
applicable bonus period.

         4.3 Stock Options. The Board of Directors of Tango shall grant to
Employee options to purchase shares of common stock of Tango pursuant to the
terms of the 1995 Incentive Compensation Plan of Tango, which options shall (i)
be granted at such times as the Board of Directors of Tango shall grant options
to other senior executive officers of Tango, (ii) be equivalent in amount and
exercise price to options granted to other senior executive officers of Tango,
and (iii) shall vest and become exercisable at the same rates and times as
options granted to other senior executive officers of Tango.

         4.4.     Insurance.

                  (a) Life and Other Insurance. The Company and Tango shall
provide to Employee such term life and group travel, accident, accidental death
and dismemberment insurance and long and short term disability insurance, or
their equivalents, as is provided from time to time for other senior executives
of the




                                       7

Company and Tango. The Company and Tango shall be entitled, at their sole
option and expense, to arrange for and keep in effect, during the term of
Employee's employment hereunder, so long as he is insurable, key man insurance
on Employee in an amount determined by the Board of Directors of Tango, such
policy or policies to name Tango or its designee as the beneficiary. Employee
shall reasonably cooperate with the Company and Tango in procuring such key man
insurance as the Company and Tango shall elect to purchase. In addition, the
Company and Tango shall maintain Employee's split dollar and deferred
compensation life insurance policies maintained by the Company immediately
prior to the consummation of the Merger.

                  (b) Medical Insurance. During the term of Employee's
employment hereunder, the Company and Tango shall, at their expense, provide or
arrange for and keep in effect, hospitalization, major medical and similar
medical and health insurance for Employee and his family, as is provided from
time to time for other senior executives of the Company and Tango.

         4.5      Vacation.  Employee shall be entitled to four (4) weeks' paid 
vacation during each year of his employment hereunder.

         4.6 Retirement Benefits. During the term of his employment hereunder,
Employee shall have the same rights as other senior executive officers of the
Company and Tango to participate in all profit-sharing, pension and other
retirement plans as are now, or as may hereafter be, established by the Company
and Tango; provided, however, that for so long as any Company employee benefit
plans are maintained in effect in accordance with Section 5.6 of the Merger
Agreement, Employee shall have the option to continue to participate in such
plans.

         4.7 Out-of-Pocket Expenses. The Company and Tango shall reimburse
Employee for all reasonable out-of-pocket expenses incurred by Employee in
connection with the performance of his duties hereunder upon presentation of
appropriate vouchers therefor.

         4.8 Automobile Expense Allowance. During the term of Employee's
employment hereunder, the Company and Tango shall pay to Employee an automobile
allowance of $600 per month.

         4.9 Moving and Relocation Expenses. In addition to the salary and
benefits set forth in this Section 4, the Company and Tango shall provide to
Employee the following benefits in connection with his moving and relocating to
Wisconsin:

                  (i) Employee agrees to use reasonable efforts to sell his
         residence located at 1345 St. Andrews, Wichita, Kansas (the
         "Residence") prior to the date he relocates to




                                       8

<PAGE>   9



         Wisconsin, which relocation shall occur no later than the first
         anniversary of the date hereof. The Company and Tango agree to
         reimburse Employee for his reasonable out-of-pocket expenses incurred
         in connection with his efforts to sell the Residence, including, but
         not limited to, real estate broker's commissions. If Employee is
         unable to sell the Residence prior to the date he relocates to
         Wisconsin then the Company or Tango shall purchase the Residence for a
         purchase price determined as follows: each of Employee and the Company
         or Tango shall obtain an appraisal of the value of the Residence from
         licensed real estate appraisers selected by each of them; if such
         appraisals do not vary by more than $10,000, the purchase price to be
         paid shall be the average of the two appraisals; if such appraisals
         vary by more than $10,000, then the two appraisers shall jointly
         appoint a third appraiser, whose appraisal shall be final and binding
         on the Company, Tango and Employee. The Company and Tango shall bear
         the cost of the appraisals and all other costs and expenses related to
         such purchase and sale of the Residence from Employee.

             (ii) until such time as Employee shall have completely relocated
         to Wisconsin, the Company and Tango shall (A) provide Employee a two
         (2) bedroom furnished apartment (at a monthly rental rate not to
         exceed $1,500), and (B) reimburse Employee for all reasonable costs
         and expenses in commuting from Wichita, Kansas to Brookfield,
         Wisconsin.

            (iii) the Company and Tango shall pay on behalf of Employee or
         reimburse Employee, at Employee's option, for the actual costs paid to
         third parties relating to Employee's relocation from Kansas to
         Wisconsin, including, but not limited to, (a) reasonable moving
         company expenses and insurance, and (b) reasonable travel expenses for
         Employee and his spouse from Kansas to Wisconsin in order to enable
         Employee and his spouse to locate a suitable residence in Wisconsin.

SECTION 5.  Restrictive Covenants.

         (a) Employee acknowledges that the covenants herein are necessary to
protect the goodwill and other value of the Company and Tango and in view of
the unique and essential nature of the services Employee is to perform

         (b) Employee further acknowledges that his services hereunder are of a
special, unique and extraordinary character and that his positions with the
Company and Tango place him in a position of confidence and trust with the

         employment;

            (iii) while he is in the Company's and Tango's employ and through

         (f) Employee agrees that upon the termination of his employment for
any reason whatsoever (whether voluntarily or involuntarily) he will not take
with him or retain without written authorization, and he will promptly deliver
to the Company or Tango, originals and all copies of all papers, files or other
documents containing any Confidential Information and all other property

Notwithstanding the immediately preceding sentence, Employee shall be permitted

independently developed and disclosed by others, or that otherwise enters the

         (h) Employee acknowledges that irreparable loss and injury would
result to the Company and Tango upon the breach of any of the covenants

this Section 5. The parties hereto agree that all references to Tango in this
Section 5 shall include, unless the context otherwise requires, all

         2.1 Title. Employee shall serve as the President of the Company, and
as such, Employee will report directly to the Board of Directors of the
Company. Employee's duties as President are set forth in Section 2.3. At no

executive offices in Brookfield, Wisconsin not later than the first anniversary
of the Closing Date (as defined in the Merger Agreement); provided, further,
that the Company may not transfer Employee to any other location without

and responsibilities comparable to those of Employee.

         2.3 Duties. Employee, as President, jointly with the Company's Chief

all reasonable action in order to effectively implement the foregoing
provisions of this Section 2.3, including, but not limited to, the adopting of
procedures and policies to ensure the sharing of authority and responsibilities
by the Employee and the CEO, using best efforts to clearly communicate their
shared authority and responsibilities to the Company's employees, vendors,
clients, advisors, lenders and investors and otherwise ensuring that Employee
is provided with access to all members of management and all employees,
commensurate with the access provided to the CEO with respect to all policy and
strategy decisions.

SECTION 3.  Term; Payments Upon Termination.

         3.1 Term. The employment of Employee hereunder shall commence on the
Closing Date (as such term is defined in the Merger Agreement) and shall
continue until the earlier of (a) the third anniversary of the Closing Date
(the "Original Term") or (b) the occurrence of any of the following events:

              (i) the death or disability of Employee (disability meaning a
         physical illness or incapacity that prevents Employee totally and
         permanently from performing all of the substantial and material duties
         of his then current position of employment with the Company; provided,
         however, that a disability shall be considered to exist only if
         Employee is prevented for a period of three (3) consecutive months
         following the date such condition commenced and at the end of such
         three (3) month period he remained so prevented, or if, prior to the
         expiration of such three (3) month period, Employee's attending
         physician provides the Company with a written prognosis that the
         illness, injury or other incapacity that results in Employee's current
         disabled condition may be reasonably expected to prevent Employee from
         performing all of the substantial and material duties of his then
         current position of employment with the Company for a period of at
         least six (6) consecutive months;

             (ii) the mutual written agreement of the parties hereto terminate
         Employee's employment hereunder;

            (iii) the Company's termination of Employee's employment hereunder
         for "cause." For the purposes of this Agreement, "cause" for
         termination of Employee's employment shall exist only (x) if Employee
         is convicted of, or pleads guilty to, any act of fraud,
         misappropriation or embezzlement, or any felony, (y) if Employee has
         engaged in conduct or activities materially damaging to the Company,
         monetarily or otherwise (it being understood, however, that neither
         conduct nor activities pursuant to Employee's exercise of his good
         faith



                                       3

<PAGE>   4



         business judgment nor unintentional physical damage to any property of
         the Company by Employee shall be a ground for such a determination by
         the Company) or (z) if Employee has willfully and continuously failed
         to substantially perform his duties hereunder (other than any such
         failure resulting from incapacity due to physical or mental illness),
         after a written demand for substantial performance is delivered to
         Employee that specifically identifies the manner in which the Company
         believes that Employee has not substantially performed those duties,
         and Employee has failed to resume substantial performance of such
         duties on a continuous basis within fourteen (14) days after receiving
         such demand. Termination for cause shall be made only upon the vote of
         not less than a majority of the directors then in office, after
         reasonable notice to Employee and an opportunity for Employee,
         together with counsel, to be heard before a duly called meeting of the
         Board; or

             (iv) the Employee's termination of his employment with the Company
         for "good reason" upon reasonable notice to the Company. For purposes
         of this Agreement, "good reason" shall exist if (x) the Company
         materially fails to comply with any of the provisions of this
         Agreement, other than isolated, insubstantial or inadvertent failures
         not occurring in bad faith and which are remedied by the Company
         promptly after receipt of notice thereof given by Employee, (y) the
         Company shall diminish Employee's title, duties, base salary or
         benefits, except, in the case of base salary or benefits, if such
         diminution is part of an overall diminution of base salary and
         benefits for all senior executive officers, or (z) any breach by the
         Company of its agreements set forth in Section 5.17 of the Merger
         Agreement.

              The Original Term hereof, and any renewal term, shall be
automatically renewed for an additional one (1) year period unless either
Employee or the Company gives notice to the other party that it does not wish
to renew this Agreement at least ninety (90) days prior to the expiration of
such Original Term or renewal term, as the case may be.

         3.2  Payments Upon Termination.

         (a) If during the Original Term hereof, or any renewal term,
Employee's employment is terminated (i) by the Company without "cause" or, (ii)
by Employee for "good reason," then the Company shall pay to Employee the
Employee's Base Salary at the rate in effect at the time notice of termination
is given, together with any applicable bonuses (without pro-ration as provided
in Section 4.2) and rights and benefits the Employee may have under employee
benefits plans and programs of the Company in existence as of the date of such
termination, all for the period




                                       4

(the "Extended Period") equal to the greater of (x) the balance of the Original
Term or renewal term, as applicable, or (y) the twelve (12) month period
following the date of such termination.

         (b) If during the Original Term, or any renewal term, Employee's
employment is terminated as a result of the death or disability of Employee
(disability having the meaning set forth in Section 3.1(i) of this Agreement),
the Company shall continue to pay Employee (or his estate) his Base Salary at
the rate in effect on the date of death or the date disability is conclusively
determined, as applicable, together with any applicable bonuses (without
pro-ration as provided in Section 4.2) and rights and benefits the Employee may
have under employee benefits plans and programs of the Company in existence as
of the date of such termination, all for the twelve (12) month period following
the date of death or the date disability is conclusively determined, as
applicable.

         (c) If during the Original Term, or any renewal term, Employee's
employment is terminated (i) by the Company for "cause" or (ii) Employee for
any reason other than "good reason," then the Company shall pay Employee the
Base Salary (as hereinafter defined) through the effective date of termination
at the rate in effect at the time notice of termination is given, and the
Company shall have no further obligations to Employee under this Agreement
subject to the rights and benefits the Employee may have under employee
benefits plans and programs of the Company in existence as of the effective
date of such termination, if any, which shall be determined in accordance
therewith.

         3.3 Payments Upon Change of Control. During the Original Term hereof,
or any renewal term, if there is a Change of Control (as hereinafter defined)
and any one of (i) the Employee's location of employment as set forth herein
changes, (ii) the Company takes any action which would entitle Employee to
terminate his employment for "good reason" pursuant to clauses (x) or (z) of
the definition thereof, or (iii) the Company shall diminish Employee's title,
duties, base salary or benefits (each of the events described in the foregoing
clauses (i), (ii) and (iii) being herein referred to as a "Triggering Event"),
then Employee may at his election, at any time within one year after any such
Triggering Event, terminate this Agreement (a "Voluntary Termination"), and
Employee shall be entitled to the following compensation, in addition to the
other compensation and bonuses provided for herein:

             (a) in lieu of any further salary payments to Employee for
         periods subsequent to the date of Voluntary Termination, the Company
         shall pay as severance payment to Employee, no later than the fifth
         day following the date of Voluntary Termination, a lump-sum severance
         payment to Employee equal




                                      5

         to 300% of Employee's annual base salary rate in effect as of the date
         of Voluntary Termination or, if greater, such rate as may be in effect
         immediately prior to the Change of Control. In addition, Employee
         shall be paid an amount equal to 300% of his bonus for the calendar
         year immediately preceding the year in which such Voluntary
         Termination shall occur or, if greater, his bonus for the full
         calendar year preceding the year in which such Change of Control
         occurs; and

                  (b) the Company shall provide Employee with all employee
         benefits and programs of the Company which the Employee was entitled
         to receive or participate in immediately prior to the effective date
         of the Voluntary Termination for the thirty six (36) month period
         following the date of such Voluntary Termination.

         For the purposes of this Agreement, "Change of Control" shall mean the
occurrence of any of the following events:

                  (i)   any "person" or "group" (as such terms are used under
Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as Amended
(the "Exchange Act"), whether or not such Sections are applicable) is or
becomes, whether by means of any issuance or direct or indirect transfer of
securities, merger, consolidation, liquidation, dissolution or otherwise, the
"beneficial owner" (as that term is used under Rules 13d-3 and 13d-5 under the
Exchange Act, whether or not such rules are applicable, except that a "person"
or "group" shall be deemed to have "beneficial ownership" of all shares that he
or it has the right to acquire, whether such right is exercisable immediately
or only after the passage of time or otherwise), directly or indirectly through
one or more intermediaries, of 35% or more of the total voting power
represented by all of the voting stock of the Company; or

                  (ii)  directly or indirectly, a transfer, sale, lease or other
disposition of all or substantially all of the assets of the Company and its
subsidiaries taken as a whole to any "person" or "group" (as such terms are
used un Sections 13(d) and 14(d) of the Exchange Act, whether or not such
sections are applicable), excluding any disposition to or among the Company
and/or one or more of its subsidiaries; or

                  (iii) any "person" or "group" (as such terms are used under
Sections 13(d) and 14(d) of the Exchange Act, whether or not such sections are
applicable) otherwise obtains the right or power (through any arrangement,
contract, proxy or other means) to elect or designate a majority of the members
of the Board of Directors then in office, without regard to whether such right
or power is exercised or invoked and without taking into account the necessity
of a special or annual stockholders meeting or the



                                       6

<PAGE>   7



taking of other procedural actions to exercise or invoke such right or power.

         Section 3.4. If pursuant to Section 3.2 or 3.3, Employee is entitled
to receive benefits under employee benefit plans subsequent to his termination
of employment and such benefits or programs cannot be made available following
termination of Employee in circumstances in which Employee is entitled thereto
hereunder, the Company shall pay Employee an amount in cash sufficient to
enable Employee to purchase such benefits or programs on his own behalf.
Employee shall retain all grants and awards issued to him under the Company's
stock incentive plans during any period subsequent to termination of Employee's

         4.1 Base Salary. For the first twelve (12) months of the term of his
employment hereunder, Employee shall be paid a salary at the annual rate of Two
Hundred Sixty Five Thousand Dollars ($265,000), payable in equal installments
in accordance with the payroll payment practices from time to time adopted by

Company may, in the discretion of the Board of Directors, pay Employee an
annual bonus (the "Annual Bonus") for each fiscal year during the term of
Employee's employment hereunder. Subject to Section 3.2 hereof, if Employee's
employment hereunder is terminated pursuant to the terms of this Agreement
prior to the end of a calendar year, his Annual Bonus with respect to that year
shall be prorated for such portion of that year as he was employed by the

options granted to other senior executive officers of the Company, and (iii)
vest and become exercisable at the same rates and times as options granted to
other senior executive officers of the Company.

hereunder, so long as he is insurable, key man insurance on Employee in an
amount determined by the Board of Directors, such policy or policies to name
the Company or its designee as the beneficiary. Employee shall reasonably
cooperate with the Company in procuring such key man insurance as the Company
shall elect to purchase. In addition, the Company shall maintain Employee's

Employee shall have the same rights as other senior executive officers of the
Company to participate in all profit-sharing, pension and other retirement
plans as are now, or as may hereafter be, established by the Company; provided,
however, that for so long as any Twister employee benefit plans are maintained
in effect in accordance with Section 5.6 of the Merger Agreement, Employee
shall have the option to continue to participate in such plans.

         4.7 Out-of-Pocket Expenses. The Company shall reimburse Employee for
all reasonable out-of-pocket expenses incurred by

following benefits in connection with his moving and relocating to Wisconsin:

              (i) Employee agrees to use reasonable efforts to sell his

         and the Company shall obtain an appraisal of the value of the
         Residence from licensed real estate appraisers selected by each of
         them; if such appraisals do not vary by more than $10,000, the
         purchase price to be paid shall be the average of the two appraisals;
         if such appraisals vary by more than $10,000, then the two appraisers
         shall jointly appoint a third appraiser, whose appraisal shall be
         final and binding on the Company and Employee. The Company shall bear
