       -------------------                                                   
first 12 months after the Closing Date, it shall give Buyer ten days' prior
written notice of its intent to assert any claim against any former customer or
supplier of CTI which, at the time of the assertion, is still a customer or
supplier of Buyer.

documents required to be filed by the Secretary of State of Delaware to amend
CTI's Certificate of Incorporation to legally change its name from "Current
Technology Inc." to a name which is not confusingly similar to "Current
Technology".  CTI shall, within 30 days after the Closing, take such action and
file such documents as shall be necessary to reflect such name change in all
states in which CTI is qualified to do business as a foreign corporation, and
shall deliver to Buyer copies of such documents evidencing such name change
filings.

  6.4  Maintenance of, and Access to, Records.  After the Closing Date, CTI
       --------------------------------------                              
shall provide Buyer with access (with an opportunity to make copies at Buyer's
expense), during normal business hours, and upon reasonable notice, to all
records relating to the Business which are retained by it in accordance with
this Agreement (other than records constituting privileged and confidential
attorney-client communications or work product).  CTI shall preserve and
maintain the books and records relating to the Business retained by CTI for at
least seven years after the Closing Date or longer if required by IRS
guidelines.

  6.5  Cooperation in Litigation.  In the event that a claim is asserted against
       -------------------------                                                
Buyer, or any of its direct or indirect subsidiaries, relating to, based in
whole or in part on events or conditions occurring or existing in connection
with, or arising out of, the Business as operated by CTI prior to the Closing
Date, or the ownership, possession, use or sale of the Acquired Assets prior to
the Closing Date, CTI agrees to cooperate with Buyer in the defense of any such

Agreement, CTI, Buffton and their Affiliates shall never use or disclose any of
the know-how, trademarks, service marks, trade names, copyrights, patents,

the extent: (i) required by law as evidenced by a written legal opinion
- -----------                                                            
addressed to Buyer, (ii) required by court order or subpoena (a copy of which
shall be provided to Buyer 10 days prior to disclosure), (iii) if necessary in
connection with any dispute, controversy or third party litigation involving

the most limited manner reasonably possible, or (iv) available in the public
domain, and (B) Buffton and CTI, and their officers, directors, employees,
attorneys and accountants, shall be entitled to utilize and disclose such
information for the purpose of preparing and filing returns and reports required
by law and for maintenance of corporate records.

       (c)  Prescribed Territory.  CTI, Buffton and their Affiliates shall
            --------------------

       (d)  Remedies. Inasmuch as any breach, or failure to comply with, Section
            --------                                                     -------
6.6 of this Agreement will cause serious, substantial and irreparable damage to
- ---
Buyer, if CTI, Buffton or any of their Affiliates should in any way breach, or
fail to comply with, the terms of Section 6.6 of this Agreement, Buyer shall be
                                  -----------
entitled to an injunction restraining CTI, Buffton and their Affiliates from
such breach or failure. All remedies expressly provided for herein are
cumulative of any and all other remedies now existing at law or in equity. Buyer
shall, in addition to the remedies herein provided, be entitled to avail itself
of all such other remedies as may now or hereafter exist at law or in equity for
compensation, and for the specific enforcement of the covenants contained
herein. Resort to any remedy provided for hereunder or provided for by law shall
not prevent the concurrent or subsequent employment of any other appropriate
remedy or remedies, or preclude the recovery by Buyer of monetary damages and
compensation.

       (e)  Severability.  Each subsection of this Section 6.6 constitutes a
            ------------                           -----------              
separate and distinct provision hereof. In the event that any provision of this
                                                                               
Section 6.6 shall finally be determined to be invalid, ineffective or
- -----------                                                          
unenforceable, every other provision of this Section 6.6 shall remain in full
                                             -----------                     
force and effect.  The invalid, ineffective or unenforceable provision shall,
without further action by the parties, be automatically amended to effect the
original purpose and intent of the invalid, ineffective or unenforceable
provision to the maximum extent enforceable under applicable law; provided,
                                                                  ---------
however,  that such amendment shall apply only with respect to the operation of
- -------                                                                        
such provision in the particular jurisdiction in which such adjudication is
made.

  6.7  Non-Solicitation.  During the period commencing on the Closing Date and
       ----------------                                                       
through and until the date five (5) years after the Closing Date, Buffton, CTI
and their Affiliates shall not, for any reason whatsoever, directly or
indirectly, call upon

                                                    CTI ASSET PURCHASE AGREEMENT
                                                                         Page 19
<PAGE>
 
or solicit any Covered Employee for the purpose or with the intent of enticing
such employee away from or out of the employ of Buyer.  As used herein, "Covered
                                                                         -------
Employee" means an employee of CTI on the Closing Date who accepts employment
- --------                                                                     
with Buyer on or promptly after the Closing Date.  Buffton will notify each of
the general managers of the hotel, restaurants and entertainment facility owned
by subsidiaries of Buffton of the foregoing obligation, but Buffton shall have
no liability if one of those general managers thereafter solicits a Covered
Employee to terminate his or her employment with Buyer if an officer of Buffton
did not have prior knowledge of such solicitation.  If, during the five-year
period following the Closing Date, Buffton or one of its subsidiaries hires a
person who is or was a Covered Employee, it will be conclusive evidence that no
violation of the first sentence of this paragraph occurred if Buffton or a
subsidiary obtains a written statement from the employee in question that he or
she has terminated or intends to terminate his or her employment with Buyer and
has not been solicited by Buffton or a subsidiary of Buffton to do so, and
neither Buffton nor CTI shall have any obligation or liability with respect
thereto.  Buffton and its subsidiaries may not unreasonably rely on such an
employee statement.  If Rogers resigns as an employee of Buyer prior to the
first anniversary of the Closing Date, Buffton and its subsidiaries agree that
they will not employ Rogers as an employee prior to such first anniversary.

  6.8  Limitations on Assignability.  To the extent that any of the contract
       ----------------------------                                         
rights of CTI to be sold, transferred or assigned hereunder are not assignable
without the consent of a third party, neither this Agreement, nor any of the
instruments or documents executed and delivered in connection herewith or
contemplated hereby, shall constitute an assignment or assumption thereof, or
attempted assignment or attempted assumption thereof, if such assignment or
attempted assignment, or assumption or attempted assumption, would constitute a
breach thereof.  If CTI has not obtained a consent or approval necessary for the
assignment of any contract right to be assigned hereunder, then (except  for
contracts terminable without penalty on 30 days or less notice, leases of office
equipment, contracts not expressly requiring consent and customer purchase
orders) CTI shall use commercially reasonable efforts where required by Buyer to
obtain such consents and approvals after the Closing, or, at Buyer's request,
shall cooperate in any reasonable and mutually acceptable arrangement to provide
to Buyer the benefits thereof subject to the performance by Buyer of Seller's
obligations arising or to be performed after the Closing thereunder.  Nothing
contained in this Section 6.8 shall require Buyer to enter into, or to accept as
                  -----------                                                   
a substitute for performance by CTI hereunder, any arrangement that would impose
any additional cost, expense or liability on Buyer, or that would deprive Buyer
of any benefits contemplated by this Agreement.

  6.9  Pre-Closing Operations of CTI.  Except as contemplated by this Agreement
       -----------------------------                                           
or as may be responsive to the transactions contemplated hereby, or as otherwise
approved in writing by Danaher, from the date hereof until the Closing Date, CTI
will conduct the Business in the ordinary course consistent with past practice.
Subject to the foregoing exceptions, from the date hereof until the Closing
Date:

       (a)  Mergers and Sales.  CTI will not merge, consolidate, or enter into a

share exchange with any other corporation or other business entity, acquire any
material stock or any material amount of assets of any other corporation or
other business entity, sell, lease, license, mortgage, pledge, or otherwise
dispose of any material assets, except (i) pursuant to existing contracts or
commitments, or (ii) in the ordinary course consistent with past practice;

       (b)  New Commitments.  CTI will not make any commitment or enter into any
            ---------------                                                     
contract or agreement that is likely to be, individually or in the aggregate,
materially adverse to CTI except in the ordinary course of business consistent
with past practice; and

       (c)  Compensation Increase.  CTI will not increase in any manner the
            ---------------------                                          
compensation or fringe benefits of any of its directors or officers, pay any
pension or retirement allowance to any directors or officers, or become a party
to, amend, or commit itself to any pension, retirement, profit-sharing, welfare
benefit plan, or employment agreement with or for the benefit of any director or
officer, other than general increases in the compensation of, and the payment of
bonuses to, officers in the ordinary course of business consistent with past
practice.

  6.10 Access to Records and Information.  From the date hereof until the
       ---------------------------------                                 
Closing Date, Buffton and CTI will, upon reasonable notice, give Danaher and its
authorized representatives reasonable access during regular business hours to
the offices, properties, books, and records of Buffton and CTI, and will furnish
to Danaher and its authorized representatives such financial and operating data
and other information as such persons may reasonably request, for the purpose of
evaluating changes in the

                                                    CTI ASSET PURCHASE AGREEMENT
                                                                         Page 20
<PAGE>
 
financial condition, results of operations, or business of CTI after the date of
this Agreement and will instruct Buffton's and CTI's employees, counsel, and
financial advisors to cooperate with Danaher in its evaluation.  Promptly after
the execution of this Agreement, CTI will send a notice to its employees of the
execution of this Agreement and request each employee to consent to the
disclosure and transfer of his employment and personnel records to Buyer and
Danaher.

  6.11 Other Offers.  From the date hereof until the termination of this
       ------------                                                     
Agreement, Buffton and CTI will not, and will use all reasonable efforts to
cause their officers, directors, employees, and agents not to, directly or
indirectly, (i) take any action to solicit or initiate any Company Acquisition
Proposal (as defined below) or (ii) engage in negotiations or enter into
agreements with any corporation or other business entity with respect to a
Company Acquisition Proposal, disclose any nonpublic information relating to
Buffton or any of its subsidiaries to, or afford access to the properties,
books, or records of Buffton or any of its subsidiaries to, any corporation or
other business entity, except to the extent required in accordance with the
fiduciary duties of Buffton's Board of Directors under applicable law, as
advised by counsel to Buffton, in connection with a Company Acquisition
Proposal.  For purposes of this Agreement, "Company Acquisition Proposal" means
                                            ----------------------------       
any good faith offer or proposal for a merger or other business combination
involving Buffton or CTI or the acquisition of any substantial equity interest
in, or a substantial portion of the assets of, Buffton or CTI, other than the
transactions contemplated by this Agreement other than a transaction involving
Buffton which contemplates the consummation of the transactions with Buyer and
Danaher provided by this Agreement.

  6.12 Notices of Certain Events.  Buffton will promptly notify Danaher of:
       -------------------------

       ----------------------------------

       (a)  Performance of Work by Buyer. Without assuming any liability for the

each calendar year following the Closing, Buyer, at its cost and expense, shall
perform the work necessary, provide the replacement products necessary, or allow
the credits necessary, to reasonably satisfy claims made by customers under
CTI's product warranties if and to the extent the cost (as measured by the

reimbursable amount described below) of such work, provision of replacement
products or allowance of credits, in the aggregate, is less than twenty five
thousand dollars ($25,000).

       (b)  Reimbursement Obligations of CTI.  If and to the extent the cost (as
            --------------------------------                                    
measured by the reimbursable amount described in Subsections (i), (ii), (iii)
                                                 ----------------------------
and (iv) of this Section 7.3(b) below) of such work, provision of replacement
    ----         --------------                                              
products or allowance of credits, in the aggregate, is more than twenty five
thousand dollars ($25,000) in a calendar year, CTI shall reimburse Buyer for any
work performed, any replacement products provided or any allowance of credit, by
Buyer, if any, in satisfaction of claims made by customers under CTI's product
warranties (only if and to the extent Buyer submits to CTI a written statement
describing the work, provision of replacement products and/or allowance of
credits and certifying (or providing evidence reasonably satisfactory to CTI)
that such work, provision of replacement products or allowance of credits is
strictly required by CTI's product warranties).  Claims by Buyer for
reimbursement from CTI after the $25,000 limit is reached each year shall be
submitted monthly by Buyer, along with the aforementioned descriptive statement,
certification or evidence, for claims for reimbursement with respect to
defective products during the preceding month, and CTI shall be obligated to pay
to Buyer the amount to which Buyer is entitled pursuant hereto.  The amount
reimbursable by CTI to Buyer shall be determined as follows:

            (i)   In the case of a replacement product for a defective product
that cannot be resold or repaired, such reimbursement shall be the cost of such
replacement product reflected on Buyer's finished-goods inventory together with
freight costs.

            (ii)  In the case of a replacement product for a defective product
that can be repaired and resold, such reimbursement shall be the lesser of (a)
the actual cost of repair or (b) the cost of such replacement product reflected
on Buyer's finished-goods inventory together with freight costs.

            (iii) In the case of work performed in repairing a defective product
and returning the product to the customer, such reimbursement shall be the sum
of Buyer's material (at cost), 150% of the direct labor costs (but not overhead
charges or employee benefit burden), reasonable travel expenses, freight costs
and any other reasonable out-of-pocket costs and expenses incurred in connection
with such work.

            (iv)  In the case of a credit allowance to a customer for a
defective product that cannot be repaired and resold, such reimbursement shall
be the amount invoiced to the customer.

       Buyer shall not be obligated to do any such work, to provide any such
replacement products, or to provide any allowances, and may require prepayment
from CTI before doing any such work, providing any such replacement products or
allowing any credits.

       (c)  Review of Claims over $2,000 by CTI.  Prior to incurring any expense
            -----------------------------------                                 
(including allowing a credit against an outstanding Account Receivable) in
connection with remedying any individual product warranty claim having an
estimated reimbursable amount exceeding $2,000, Buyer shall notify CTI in
writing of the claim, the proposed remedy and the estimated reimbursable amount
of the proposed remedy.  CTI shall have the right to review the claim, the
proposed remedy and the estimated reimbursable amount thereof and to object in
writing to Buyer in any regard thereto.  CTI shall provide Buyer with its
written objections within five business days of its receipt of Buyer written
notice.  At least five business days prior to incurring any expense (including
allowing a credit against an outstanding Account Receivable) with respect to
such claim, Buyer shall notify CTI of its intent with regard to the proposed
remedy and any adjustments to the estimated reimbursable amount thereof. CTI's
objection to the claim, the proposed remedy and the estimated reimbursable
amount thereof shall not relieve CTI of its obligation to reimburse Buyer,
provided that the work performed, the provision of replacement products or the
allowance of a credit, is strictly required by CTI's product warranties.
