     WHEREAS, Medical desires to acquire from the Stockholders and the 
Stockholders desire to convey to Medical all of the Sharps Stock in exchange 
solely for the Medical Stock (as defined in Section 1.02 below); and

     WHEREAS, it is the intent of the Stockholders and Medical for the 
exchange of stock contemplated by this Agreement to qualify as a tax-free 
exchange under Section 368 of the Internal Revenue Code of 1986, as amended;

     NOW, THEREFORE, in consideration of the premises and the mutual 
covenants contained herein, the parties hereto agree as follows:

                                  ARTICLE I

                            PLAN OF REORGANIZATION

     1.01 ACQUISITION OF SHARPS STOCK.  In reliance upon the representations 
and warranties herein and subject to the terms and conditions hereof, on the 
Closing Date (as defined in Section 1.03(a) below), Medical shall acquire 
from the Stockholders and the Stockholders shall convey to Medical all of the 
Sharps Stock.

     1.02 EXCHANGE OF SHARES.  Medical and the Stockholders agree that the 
Sharps Stock shall be exchanged with Medical for an aggregate of One Million 
(1,000,000) shares of Series A 10% Voting Convertible Preferred Stock, $.01 
par value, of Medical ("Medical Stock") such that each share of Sharps Stock 
outstanding on the Closing Date, not to exceed 7,000,000 shares of Sharps 
Stock in the aggregate, is exchanged for .142858 shares of Medical Stock (the 
"Exchange Ratio"), with any excess shares of Sharps Stock resulting in a 
reduction in the per-share Exchange Ratio.  In the event that Sharps has 
fewer than 7,000,000 shares of Sharps Stock outstanding on the Closing Date, 
the Exchange Ratio shall be proportionately increased.  On the Closing Date, 
the following numbers of shares of Medical Stock, totaling 1,000,000 shares,

                  REPRESENTATIONS, WARRANTIES AND AGREEMENTS
                   OF SHARPS AND THE FOUNDING STOCKHOLDERS

     Sharps and the Founding Stockholders represent, warrant to and agree 
with Medical that:

     2.01  CAPITALIZATION.  The authorized capital stock of Sharps is Ten 
Million (10,000,000) duly authorized shares of common stock, $.01 par value, 
of which Seven Million (7,000,000) shares are validly issued, outstanding, 
fully paid and nonassessable.

     2.02  ABSENCE OF RIGHT TO PURCHASE.  No person, firm or corporation has 
any subscription, warrant, agreement, option or right capable of becoming an 
agreement for the purchase of any of the Sharps Stock or of any authorized 
but unissued shares of the capital stock of Sharps, other than herein granted 
to Medical.

     2.03  FINANCIAL STATEMENTS.  The audited financial statements for the 
interim nine-month period ended September 30, 1997 of Sharps, contained in 
EXHIBIT "A" attached hereto (the "Sharps Financial Statements"), present 
fairly the financial position of Sharps at said date and the results of 
operations of Sharps for the fiscal period then ended and the interim periods 
covered thereby and were prepared in conformity with generally accepted 
accounting principles. Sharps at 

                                       5


present has no liability, absolute or contingent, of the type required to be 
reflected on a balance sheet or notes thereto prepared in accordance with 
generally accepted accounting principles which is not shown on the Sharps 
Financial Statements, other than current liabilities incurred in the ordinary 
course of business since September 30, 1997.

     2.04  ABSENCE OF CERTAIN CHANGES.  Since September 30, 1997, there has 
not been, and the Founding Stockholders and Sharps warrant that pending the 
Closing there will not be:

     (a)   Any damage, destruction or loss, whether or not covered by 
insurance, materially and adversely affecting the property or business of 
Sharps; or

     (b)   Any change in the financial condition of Sharps, whether in assets 
or liabilities, other than transactions incurred in the ordinary course of 
business which on the whole shall not have been materially adverse.

     2.05  INCORPORATION AND STATUS.  Sharps is a corporation duly organized, 
validly existing and in good standing under the laws of the State of Texas. 
Sharps has corporate power to own its properties and carry on its business in 
the manner in which such business is now being conducted.  Sharps is duly 
qualified as a foreign corporation and is in good standing to do business in 
each jurisdiction in which the property owned, leased or operated by it or 
the nature of the business conducted by it makes such qualification necessary.

     2.06  ABSENCE OF EMPLOYMENT CONTRACTS.  There are no contracts of 
employment, contracts for managerial services, labor contracts or collective 
bargaining agreements presently in existence between Sharps and any of its 
employees or any union, other than the usual and customary parol employment 
agreements having a term equivalent to the payroll period, except as set 
forth in EXHIBIT "B" attached hereto.

     2.7   ABSENCE OF PENSION AND PROFIT SHARING PLANS.  Sharps has no 
pension plan, retirement plan, profit sharing plan or stock option plan, 
group insurance, welfare or similar plan other than provisions for vacations, 
group life, group hospitalization policies and sick leave, substantially the 
same as those which were in effect during the period covered by the Sharps 
Financial Statements.

     2.8   ABSENCE OF LITIGATION.  Sharps is not involved in any litigation 
which would materially and adversely affect its financial condition, 
properties, business operations or prospects, nor, to the knowledge of its 
officers or of the Stockholders, is any such litigation pending or 
threatened.  Sharps has not been, nor is it now, under investigation with 
respect to any charge concerning any material violation of any provision of 
federal, state, local or administrative regulation with respect to its 
business.

     2.9   RIGHTS USED IN CONDUCT OF BUSINESS.  Sharps is the unqualified 
owner of all trademarks, trade names or other marks which it uses in its 
business and owns or possesses adequate rights (including rights under 
licenses) to use all patents, inventions and copyrights now 

                                       6


used in the conduct of its business, and has not received any notice of 
conflict with the asserted rights of others.  Sharps is not a party to any 
agreement under which it is obligated to pay royalties or license fees to 
others in connection with intellectual property rights.

     2.10  PERFORMANCE OF CONTRACT OBLIGATIONS.  To the best knowledge and 
belief of the officers of Sharps and the Founding Stockholders, Sharps has in 
all material respects performed all obligations required to be performed by 
it under all material agreements, leases or other documents to which Sharps 
is a party, and neither the officers of Sharps nor the Founding Stockholders 
know of any default in any material respect under any such agreements, leases 
or other documents to which Sharps is a party.

     2.11  CONTRACTS.  True and correct copies of all such contracts, 
agreements, leases, licenses, franchises, applications and other instruments 
to which Sharps is a party have been made available to Medical by Sharps.  
Sharps has not violated and is not now in default as to any such agreements 
in any material respect.

     2.12  ABSENCE OF DECREES, ETC.  Sharps is not in default with respect to 
any judgment, order, writ or injunction, decree, rule or regulation of any

decree or order which materially adversely affects its business or profits or 
its condition, financial or otherwise, or any of its assets or property.

     2.13  ABSENCE OF CONFLICTING AGREEMENTS.  Sharps is not a party to any 
agreement, contract, note or other document requiring the observance by 
Sharps of any restrictions or performance of any covenant which will be

charter or other restriction which is being violated by it in the conduct of 
its business.

insurance with reputable insurers, adequately protecting it against damage to 
or loss of property and against tort liabilities.

     2.16  INDEMNIFICATION BY THE FOUNDING STOCKHOLDERS.  From and after 
consummation of the transactions contemplated by this Agreement, the Founding 
Stockholders will, at any time and from time to time upon the written request 
of Medical, indemnify and hold harmless Medical against and from all loss, 
cost, damage, liability and expense incurred or claimed in respect of:

     (a)   LIABILITIES.  Any liability of Sharps of any nature, whether 
accrued, absolute, contingent or otherwise, existing as of the date of the 
balance sheets contained in the Sharps Financial Statements and which creates 
or has created a material liability against Sharps prior to the Closing Date, 
regardless of whether:
     
           (i)   Such mutual liability is of a type required to be reflected on
     a balance sheet or in notes appended thereto, in accordance with generally
     accepted accounting principles, and which is not so reflected or reserved
     against in Sharps's balance sheet or notes 

                                       7


     appended thereto (including, but without limitation, any tax liability, 
     whether accrued in respect of or measured by the income of Sharps for any 
     period ending on or prior to the Closing Date) or otherwise existing, to 
     the extent not so reflected or reserved against; or
           
           (ii)  Such liability is of a type which arises or has arisen under
     such circumstances that Sharps could not be deemed to have been aware
     thereof, whether as to accrual of such liability or liquidation of the
     amount thereof;
           
     (b)   BREACH OF WARRANTY.  Any damage or deficiency resulting from any
