                                STATE OF ARIZONA
                 AMENDED AND RESTATED ARTICLES OF INCORPORATION
                                       OF
                        ORTHOPAEDIC BIOSYSTEMS LTD., INC.


         Pursuant to the provisions of Arizona Revised Statutes, Section 10-1003
and Section 10-1007, the undersigned corporation, pursuant to a resolution duly
adopted by its Board of Directors and adopted by the shareholders of the
corporation in the manner prescribed by law, hereby adopts the amended and
restated articles of incorporation as follows:

         FIRST: The name of the corporation is Orthopaedic Biosystems Ltd., Inc.

         SECOND: The purposes for which the corporation is organized include the
transaction of any or all lawful business for which corporations may be
incorporated under Chapter 1 of Title 10, Arizona Revised Statutes, at any time.
The character of business which the corporation initially intends actually to
conduct in the State of Arizona is the manufacture, distribution and sale of
medical products consisting primarily of orthopaedic fixation and implant
devices.

         THIRD: The aggregate number of shares that the Corporation shall have
authority to issue is 25,000,000 shares, of which 20,000,000 shares shall be
Common Stock, no par value, and 5,000,000 shares shall be Preferred Stock, no
par value.

         On the effective date of these Amended and Restated Articles of
Incorporation (the "Effective Date"), the Common Stock of the corporation will
be split on a two-for-three basis so that each share of Common Stock issued and
outstanding immediately prior to the Effective Date shall automatically be
converted into and reconstituted as two-thirds of a share of Common Stock (the
"Reverse Split"). Each holder of a certificate or certificates which immediately
prior to the Effective Date represented outstanding shares of Common Stock (the
"Old Common Stock") shall be entitled to receive upon surrender of such
certificates a certificate or certificates representing the number of shares of
Common Stock (the "New Common Stock") into which and for which the shares of the
Old Common Stock are split under the terms hereof. From and after the Effective
Date, Old Common Stock certificates shall represent only the right to receive
New Common Stock certificates. No fractional shares shall be issued by the
Corporation as a result of the Reverse Split. In lieu thereof, each shareholder
whose shares of Common Stock are not evenly divisible will receive one
additional share of Common Stock for the fractional share that such shareholder
would otherwise be entitled to as a result of the Reverse Split.

         Until automatic conversion simultaneously with the payment to the
Corporation of the purchase price of the Corporation's Common Shares sold by the
Corporation in its first underwritten public offering, made pursuant to a
registration statement filed on Form S-1 (or on such other form for which the
Corporation and the offering qualify), all Preferred Stock is designated Class A


   2



Convertible Preferred Stock, the rights, preferences, restrictions and other
matters relating to which are as follows:


         1. Dividends. There are no dividends (cumulative or non-cumulative) on
Class A Convertible Preferred Stock, however, Class A Convertible Preferred
Stock shall be entitled to all dividends declared on Common Stock on an
as-converted basis, as if the Class A Convertible Preferred Stock had been
converted into Common Stock.

         2. Liquidation Preference.

                  (a) In the event of any liquidation, dissolution or winding up
of this Corporation, either voluntary or involuntary, the holders of Class A
Convertible Preferred Stock shall be entitled to receive, prior and in
preference to any distribution of any of the assets of this Corporation to the
holders of Common Stock by reason of their ownership thereof, an amount per
share equal to $2.00 for each outstanding share of Class A Convertible Preferred
Stock before any payment shall be made on any assets distributed to the holders
of Common Stock. If, upon the occurrence of such event, the assets and funds
thus distributed among the holders of the full aforesaid preferential amounts,
then, the entire assets and funds of the Corporation legally available for
distribution shall be distributed ratably among the holders of the Class A
Convertible Preferred Stock in proportion to the amount of such stock owned by
each such holder.

                  (b) Upon the completion of the distribution required by
Subparagraph (a) of this Section 2, if assets remain in this Corporation, the
holders of the Common Stock of this Corporation shall next receive an amount
equal to $1.50 per Share before any further payment be made on any assets
distributed to the holders of the Class A Convertible Preferred Stock.

                  (c) After the distributions described in Subparagraphs (1) and
(b) above have been paid, the remaining assets of the Corporation available for
distribution to Shareholders shall be distributed among the holders of Class A
Convertible Preferred Stock and Common Stock pro rata based on the number of
shares of Common Stock held by each (assuming full conversion of all such Class
A Convertible Preferred Stock).

                  (d) The liquidation preferences set forth in this Section 2
shall cease to apply if the Corporation (i) sells additional equity securities
in a private financing or financings in the aggregate amount of $3,000,000 or
more, or (ii) receives payment of the purchase price for the Corporation's
Common Stock sold by the Corporation in its first underwritten public offering
("IPO"), as defined more completely in Section 3 of this Article Third,
whichever shall first occur.

         3. Automatic Conversion Upon Public Offering. Each share (or warrant to
purchase shares) of Class A Convertible Preferred Stock shall convert,
automatically and without any action on the part of the holder thereof, into
that number of fully paid and non-assessable Common Shares 

                                       2

   3

(or warrants to purchase Common Shares) for each share (or warrant to purchase
shares) of Class A Convertible Preferred Stock as determined in accordance with
Section 5 below, simultaneously with the payment to the Corporation of the
purchase price of the Corporation's Common Shares sold by the Corporation in its
first underwritten public offering, made pursuant to a registration statement
filed on Form S-1 (or on such other form for which the Corporation and the
offering qualify) with the Securities and Exchange Commission under the
Securities Act of 1933, as amended. The Corporation shall provide prior written
notice to each holder of Class A Convertible Preferred Stock of its intention to
undertake a public offering of its Common Stock. Such notice shall include a
statement notifying the holder thereof of the automatic conversion of the Class
A Convertible Preferred Stock upon consummation of the public offering. The
Corporation may require that the holder of Class A Convertible Preferred Stock
surrender the certificates evidencing such holder's Class A Convertible
Preferred Stock prior to delivery to the holder of certificates evidencing the
Common Shares issued upon the foregoing automatic conversion. Notwithstanding
the foregoing, no automatic conversion shall occur unless (i) the Corporation
sells $10,000,000 or more of its Common Stock at a price of $4.00 or more per
share in the IPO described above, or (ii) more than 50% of the Class A
Convertible Preferred stock is converted into Common Stock in accordance with
the optional conversion rights conferred under Section 4 of this Article Third.

         4. Conversion at Option of Holders. Holders of Class A Convertible
Preferred Stock may, at their option, upon surrender of the certificates
therefor, convert any or all of their shares of Class A Convertible Preferred
Stock into fully paid and non-assessable Common Shares at any time after
issuance thereof. Each share of Class A Convertible Preferred Stock shall be
convertible at the office of the Corporation or the office of any transfer agent
designated by the Corporation into that number of fully paid and non-assessable
Common Shares (calculated as to each conversion to the nearest 1/100th of a
share) as shall be equal to the number obtained by dividing the Issuance Price
(as hereinafter defined) per share of Class A Convertible Preferred Stock by the
Conversion Price computed as hereinafter set forth (the "Conversion Price") in
effect of the Class A Convertible Preferred Stock. The "Issuance Price" for the
Class A Convertible Preferred Stock is $2.00 per share and the initial
Conversion Price of the Class A Convertible Preferred Stock is $2.00. The
Conversion Price is subject to adjustment from time to time as provided in
Section 5 hereof.

         No fractional Common Shares shall be issued upon conversion of the
Class A Convertible Preferred Stock, but, in lieu of any fraction of Common
Shares which would otherwise be issuable in respect of the aggregate number of
such shares surrendered for conversion at one time by the same holder, the
Corporation shall pay in cash an amount equal to the product of (a) the fair
market value of one common share on such day as determined in good faith by the
Board of Directors of the Corporation, and (b) such fraction of one share.

         A number of authorized but unissued Common Shares sufficient to provide
for the conversion of the Class A Convertible Preferred Stock outstanding upon
the basis hereinbefore provided shall at all times be reserved by the
Corporation, free from preemptive rights, for such conversion. If the
Corporation shall issue any securities or make any change in its capital
structure which would change the number of Common Shares into which each share
of the Class A 

                                       3

   4

Convertible Preferred Stock shall be convertible as herein provided, the
Corporation shall at the same time also make proper provision so that thereafter
there shall be a sufficient number of Common Shares authorized and reserved,
free from preemptive rights, for conversion of the outstanding Class A
Convertible Preferred Stock on the new basis. The Corporation shall comply with
all securities laws regulating the offer and delivery of Common Shares upon
conversion of the Class A Convertible Preferred Stock and shall use its best
efforts to list such shares on each national securities exchange on which the
Common Shares are listed or to have such shares admitted for quotation on the
NASDAQ National Market System if the Common Shares are admitted for quotation
thereon.

         5. Adjustments to Conversion Price. Notwithstanding anything in this
Section 5 to the contrary, no change in the Conversion Price shall be made until
the cumulative effect of the adjustments called for by this Section 5, since the
date of the last change in the Conversion Price, would change the Conversion
Price by more than 1%. However, once the cumulative effect would result in such
a change, then the Conversion Price shall be changed to reflect all adjustments
called for by this Section 5 and not previously made. Subject to the foregoing,
the Conversion Price shall be adjusted from time to time as follows:

                  (a) In the event of any consolidation of merger of the
         Corporation with any other corporation (other than a wholly owned
         subsidiary of the Corporation), or in case of any sale or transfer of
         all or substantially all of the assets of the Corporation, or in case
         of any share exchange pursuant to which all of the outstanding Common
         Shares are converted into other securities or property, the Corporation
         shall, prior to or at the time of such transaction, make appropriate
         provision or cause appropriate provision to be made so that holders of
         each share of Class A Convertible Preferred Stock then outstanding
         shall have the right thereafter to convert such shares of Class A
         Convertible Preferred Stock in the kind and amount of shares of stock
         and other securities and property receivable upon such consolidation,
         merger, sale, transfer or share exchange. If in connection with any
         such consolidation, merger, sale, transfer or share exchange, each
         holder of Common Shares is entitled to elect to receive either
         securities, cash or other assets upon completion of such transaction,
         the Corporation shall provide or cause to be provided to each holder of
         Class A Convertible Preferred Stock the right to elect the securities,
         cash or other assets into which the Class A Convertible Preferred Stock
         held by such holder shall be convertible after completion of any such
         transaction on the same terms and subject to the same conditions
         applicable to holders of the Common Shares (including without
         limitation, notice of the right to elect, limitations on the period in
         which such election shall be made and the effect of failing to exercise
         the election).

                  (b) In the event that the Corporation shall (i) pay a dividend
         or make a distribution on its Common Shares in shares of its capital
         stock, (ii) subdivide its outstanding Common Shares into a greater
         number of shares, (iii) combine the outstanding Common Shares into a
         smaller number of shares, or (iv) issue by reclassification of its
         Common Shares any shares of its capital stock, then in each such case
         the Conversion Price in effect immediately prior thereto shall be
         proportionately adjusted so that the holder of any Class 

                                       4

   5

         A Convertible Preferred Stock thereafter surrendered for conversion
         shall be entitled to receive, to the extent permitted by applicable
         law, the number and kind of shares of capital stock of the Corporation
         which such holder would have owned or have been entitled to receive
         after the happening of such event had such Class A Convertible
         Preferred Stock been converted immediately prior to the record date for
         such event (or if no record date is established in connection with such
         event, the effective date for such action). An adjustment pursuant to
         this Subparagraph (b) shall become effective immediately after the
         record date in the case of a stock dividend or distribution and shall
         become effective immediately after the effective date in the case of a
         subdivision, combination or reclassification.

                  (c) In the event that the Corporation shall at any time or
         from time to time prior to April 30, 1999 (i) issue or sell any of its
         Common Shares, or any security convertible into Common Shares,
         including the sale by the Corporation of any Common Shares in an
         underwritten public offering described in Section 3 above, or (ii)
         issue or sell any right or option to purchase Common Shares or any
         security convertible into Common Shares, for a consideration per share
         less than the Conversion Price for any of the Class A Convertible
         Preferred Stock in effect immediately prior to the time of such
         issuance or sale, then, forthwith upon such issuance or sale, the
         Conversion Price for the Class A Convertible Preferred Stock shall be
         reduced to the price at which such Common Shares are being issued or
         sold by the Corporation or the price at which such other securities are
         exercisable or convertible into Common Shares of the Corporation. Upon
         each adjustment of the Conversion Price, the holder of Class A
         Convertible Preferred Stock shall thereafter, or, in the event of an
         automatic conversion pursuant to Section 3, prior to such conversion,
         be entitled to acquire, at the Conversion Price resulting from such
         adjustment, the number of shares obtained by multiplying the Conversion
         Price in effect immediately prior to such adjustment by the number of
         shares such holder may acquire pursuant hereto immediately prior to
         such adjustment and dividing the product thereof by the Conversion
         Price resulting from such adjustment. Notwithstanding the foregoing,
         the conversion of any declared and unpaid dividends on the Class A
         Convertible Preferred Stock shall be governed by the terms set forth in
         Section 5 hereof. This subparagraph (c) shall be of no force and effect
         with respect to any transaction that takes place after April 30, 1999.

                  (d) All calculations hereunder shall be made to the nearest
         cent or to the nearest 1/100th of a share, as the case may be.

                  (e) In the event that at any time, as a result of an
         adjustment made pursuant to subparagraph (a) or (b) above, the holder
         of any Class A Convertible Preferred Stock thereafter surrendered for
         conversion shall become entitled to receive securities, cash or assets
         other than Common Shares, the number or amount of such securities or
         property so receivable upon conversion shall be subject to adjustment
         from time to time in a manner and on terms as nearly equivalent as
         practicable to the provisions with respect to he Common Shares
         contained in Subparagraphs (a) through (d) above.

                                       5
   6
      Except as otherwise provided above in this Section 5, no adjustment in the
Conversion Price shall be made for share distributions or dividends theretofore
declared and paid or payable on the Common Shares of the Corporation.

      The anti-dilution provisions of this Section 5 may be waived or modified
by the affirmative vote of the holders (acting together as a class) of all of
the then-outstanding shares of Class A Convertible Preferred Stock, provided,
however, that such holders may not modify the provisions of this Section 5 in
any manner that would adversely affect the Corporation, without the written
consent of the Corporation.

      Whenever the Corporation shall propose to take any of the actions
specified in Subparagraphs (a), (b) or (c) of the first paragraph of this
Section 5 which would result in any adjustment in the Conversion Price, the
Corporation shall cause a notice to be mailed at least thirty (30) days prior to
the date on which the books of the Corporation will close or on which a record
will be taken for such action to the holders of record of the outstanding Class
A Convertible Preferred Stock on the date of such notice. Such notice shall
specify the action proposed to be taken by the Corporation and the date as of
which holders of record of the Common Shares shall participate in any such
actions or be entitled to exchange their Common Shares for securities or other
property, as the case may be. Failure by the Corporation to give such notice or
any defect in such notice shall not affect the validity of the transaction.

      Upon any adjustment of the Conversion Price of the Class A Convertible
Preferred Stock, the Corporation shall give written notice thereof, by
first-class mail, postage prepaid, addressed to the registered holders of the
Class A Convertible Preferred Stock, at the addresses of such holders as shown
on the books of the Corporation, which notice shall state the Conversion Price
resulting from such adjustment and the increase or decrease, if any, in the
number of shares receivable at such price upon the conversion of the Class A
Convertible Preferred Stock, setting forth in reasonable detail the method of
calculation and the facts upon which such calculation is based.

      6. Voting Rights. The holders of Class A Convertible Preferred Stock shall
be entitled to notice of and to attend all meetings of shareholders of the
Corporation and shall be entitled to vote together with the holders of Common
Shares, voting as a single class, on all matters presented to the Corporation's
shareholders for approval. The holders of Class A Convertible Preferred Stock
shall be entitled to the number of votes for each share of Class A Convertible
Preferred Stock held equal to the number of shares of Common Stock into which
such share of Class A Convertible Preferred Stock is then convertible as
determined in accordance with Section 5. The holders of the Class A Convertible
Preferred Stock shall only be entitled to vote as a class or as a distinct
voting group when such rights are mandated by the Arizona Business Corporation
act or as specifically provided herein.

      Following automatic conversion of the Preferred Stock simultaneously with
the payment to the Corporation of the purchase price of the Corporation's Common
Shares sold by the Corporation in its first underwritten public offering, made
pursuant to a registration statement filed on Form S-1


                                       6
   7

rights, preferences, restrictions and other matters relating to the Preferred
Stock are as follows:

      (a) The shares of Preferred Stock may be issued from time to time in one
      or more series, each of which series may have voting powers, full or
      limited, or no voting powers, and such designations, preferences and
      relative, participating, optional or other special rights and
      qualifications, limitations and restrictions, as shall be stated and
      expressed in the resolution or resolutions adopted providing for the
      issuance of such Preferred Stock of each such series adopted by the Board
      of Directors of the Corporation, and authority to adopt such resolutions
      stating and expressing any or all of the foregoing be and hereby is
      expressly vested in the Board of Directors of the Corporation.

      (b) In particular and without limitation of the foregoing, the Board of
      Directors may establish, designate and fix the following with respect to
      each such series of Preferred Stock: the voting rights, if any, of the
      stock of any such series which may, without limiting the generality of the
      foregoing, include: (i) the right to more or less than one vote per share
      on any or all matters voted upon by the stockholders; and (ii) the right
      to vote, as a series by itself or together with other series of Preferred
      Stock or together with all series of Preferred Stock as a class, upon such
      matters, under such circumstances and upon such conditions as the Board of
      Directors may fix, including, without limitation, the right, voting as a
      series by itself or together with other series of Preferred Stock or
      together with all series of Preferred Stock as a class, to elect one or
      more directors of the Corporation; (iii) the dividend rights, if any, of
      holders of stock of each such series; (iv) the terms on which stock of
      each such series may be redeemed, if the stock of such series is to be
      redeemable; (v) the rights of holders of stock of each such series upon
      dissolution or any distribution of assets; (vi) the terms or amounts of
      the sinking fund, if any, to be provided for the purchase or redemption of
      stock of each such series; (vii) the terms upon which the stock of each
      such series may be converted into or exchanged for stock of any other
      class or classes or any one or more series of Preferred Stock, if the
      stock of such series is to be convertible or exchangeable; and (viii) such
      other designations, preferences and relative, participating, optional or
      other special rights and qualifications, limitations or restrictions
      thereof, as shall be desired to be so fixed.

      (c) The number of authorized shares of Preferred Stock may be increased or
      decreased (but not below the number of shares thereof then outstanding or
      reserved for issuance) by the affirmative vote of the holders of a
      majority of the then-outstanding shares of Common Stock, without a vote of
      the holders of the Preferred Stock, or of any series thereof, unless a
      vote of any such holders is required pursuant to the certificate or
      certificates establishing the series of Preferred Stock.

      FIFTH: The directors, other than those who may be elected by the holders
of any series of Preferred Stock then outstanding, shall be divided into three
classes effective upon the filing hereof, with the term of the first class to
expire at the 1999 annual meeting of stockholders, the term of office of the
second class to expire at the 2000 annual meeting of stockholders and the term
of office of the third class to expire at the 2001 annual meeting of
stockholders. At each annual meeting of stockholders following such initial
classification and election, directors elected to succeed those directors whose
terms expire shall be elected for a term of office to expire at the third
succeeding annual meeting of stockholders after their election.

      1. Removal of Directors. Notwithstanding any other provision of these
Articles of Incorporation or the Bylaws of the Corporation (and notwithstanding
the fact that some lesser percentage may be specified by law, these Articles of
Incorporation or the Bylaws of the Corporation), and subject to the rights of
the holders of any series of Preferred Stock then outstanding, any director, or
the entire Board of Directors, may be removed from office at any time but only
for cause by the affirmative vote of the holders of a majority of the voting
power of all of the shares of the Corporation entitled to vote generally in the
election of directors, voting together as a single class.

      2. Current Board of Directors. The number of directors constituting the
current Board of Directors of the Corporation shall not be less than five (5)
