Item 2.   Acquisition or Disposition of Assets.

Pursuant to an Agreement and Plan of Merger, dated as of August 2,
1996, as amended (the "Agreement and Plan of Merger"), among C. R.
Bard, Inc. ("Bard"), CRB Acquisition Company, a wholly-owned
subsidiary of Bard ("CRB"), and IMPRA, Inc. ("IMPRA"), on September
16, 1996 CRB was merged with and into IMPRA as a result of which
IMPRA has become a wholly-owned subsidiary of Bard.  The shares of
common stock of IMPRA outstanding immediately prior to the merger
were converted into the right to receive a pro rata portion of
$143,196,000.  The purchase price is subject to adjustment as
provided in the Agreement and Plan of Merger.  In addition, Bard
acquired certain related real estate from affiliates of IMPRA for
$3,000,000.  Such amounts were financed by Bard through borrowings.

IMPRA, a privately held company, develops, manufactures and markets
vascular grafts used for blood vessel replacement surgery.  Bard
intends to continue such business.  The Press Release, dated
September 16, 1996, is attached hereto as Exhibit 99 and is
incorporated herein by reference.

     The following Unaudited Pro Forma Combined Condensed Balance
     Sheet as of June 30, 1996 and the Unaudited Pro Forma Combined
     Condensed Statements of Income for the twelve months ended
     December 31, 1995 and six months ended June 30, 1996 give
     effect to the merger described in Item 2 accounted for under
     the purchase method of accounting.  The Unaudited Pro Forma
     Combined Condensed Financial Statements are based on the
     historical Consolidated Financial Statements of Bard and IMPRA
     under the assumptions and adjustments set forth in the
     accompanying Notes to the Unaudited Pro Forma Combined
     Condensed Financial Statements.

     The Unaudited Pro Forma Combined Condensed Balance Sheet
     assumes that the merger was consummated on June 30, 1996 and
     the Unaudited Pro Forma Combined Condensed Statements of
     Income assumes the merger was consummated on January 1, 1995.
     The fiscal year of Bard ends on December 31 and the fiscal
     year of IMPRA ends on June 30. For purposes of presenting the
     Unaudited Pro Forma Combined Condensed Statements of Income
     the historical statements of IMPRA were compiled on a calendar
     year  basis  ended  December  31,  1995,  and  six  months
     ended June 30, 1996 consistent with Bard's calendar year-end.

     The pro forma adjustments are based on the Agreement and Plan
     of Merger which provides for IMPRA common stockholders to
     receive $143,196,000.  Bard utilized borrowings to finance the
     merger.  For purposes of presenting the Unaudited Pro Forma
     Combined Condensed Balance Sheet, IMPRA's assets and
     liabilities have been recorded at their estimated fair market
     values and the excess purchase price has been assigned to
     goodwill. These fair values are based on preliminary
     estimates. Upon completion of a detailed review of assets and
     liabilities, including intangibles, certain adjustments may be
     required to finalize the purchase accounting that could be
     material to the Company's financial statements.

     The Unaudited Pro Forma Combined Condensed Statements of
     Income exclude any benefits that result from the merger due to
     synergies that may be derived and the elimination of
     duplicative efforts.

     The Unaudited Pro Forma Combined Condensed Financial
     Statements may not be indicative of the results that actually
     would have occurred if the merger had been consummated on the
     dates indicated or which may be obtained in the future.  The
     Unaudited Pro Forma Combined Condensed Financial Statements
     should be read in conjunction with the historical Consolidated
     Financial Statements and Notes for IMPRA and Bard.

                 NOTES TO UNAUDITED PRO FORMA 
                COMBINED CONDENSED BALANCE SHEET
                                
The Unaudited Pro Forma Combined Condensed Balance Sheet gives
effect to the merger, which was accounted for under the purchase
method of accounting, as if it had been consummated on June 30,
1996.

The following is a summary of adjustments reflected in the
Unaudited Pro Forma Combined Condensed Balance Sheet:

1)   Represents the settlement of IMPRA's related party notes
     receivable at the date of merger.  These proceeds have been
     presented as a reduction to the long-term debt financing
     required.

2)   Represents the acquisition of the Tempe manufacturing facility
     and adjustments to reflect the fair value of IMPRA's property,
     plant and equipment.

3)   Represents the adjustment required to record goodwill related
     to the merger and adjustments to reflect the fair value of
     IMPRA's intangibles.  The purchase price of $143,196,000 has
     been adjusted to include the direct costs of the acquisition
     paid by Bard.

4)   Represents the issuance of debt and deferral of debt issuance
     costs to acquire the outstanding shares of IMPRA.  Although
     the acquisition was initially financed with commercial paper,
     the Company anticipates refinancing approximately this amount
     with long-term debt in the fourth quarter.  The long-term debt
     will be at higher interest rates.  For pro forma purposes
     long-term debt assumptions were utilized.

5)   Represents the repayment of various bank notes payable at the
     time of closing.

6)   Represents direct acquisition costs and one-time charges to be
     incurred by Bard related to the integration of the IMPRA
     business and their associated tax effects.

7)   Represents the elimination of IMPRA's historical equity.

             NOTES TO UNAUDITED PRO FORMA COMBINED
                 CONDENSED STATEMENTS OF INCOME

The Unaudited Pro Forma Combined Condensed Statements of Income
have been prepared to reflect the merger as if it occurred on
January 1, 1995.  The merger has been accounted for under the
purchase method of accounting.  The excess of the purchase price
over the fair value of the net assets acquired (goodwill) is being
amortized on a straight-line basis over a 40-year period.

The following is a summary of adjustments reflected in the
Unaudited Pro Forma Combined Condensed Statements of Income:

1)   Represents the amortization of additional goodwill over 40
     years and the adjustment to depreciation resulting from the
     acquisition of the Tempe manufacturing facility.

2)   Represents one-time charges to be incurred by Bard related to
     the integration of the IMPRA business.

3)   Represents the increase in interest expense resulting from the
     merger.  The acquisition was financed with borrowings at an
     assumed long-term rate of 7.25%.  Interest expense includes
     amortization of long-term debt issuance costs.

4)   Represents the tax effect of the Unaudited Pro Forma Combined
     Condensed Statements of Income adjustments, excluding the
     goodwill amortization.

Statements") audited by IMPRA's current independent accountants,
which audit shall include a physical inventory that representatives

Adjustments to the Effective Time Balance Sheet contained in such
written objection within thirty (30) days of his receipt of such
written objection.  If Representative shall fail to notify Buyer in
writing of his disapproval of the Proposed Adjustments within said
thirty (30) day period, or Representative notifies Buyer of his
approval of such Proposed Adjustments within said thirty (30) day
period, such adjustments shall be made to the Effective Time
Balance Sheet, and the Effective Time Balance Sheet, as so

disapproval of any or all of the Proposed Adjustments within said

agreement with respect to the Proposed Adjustments and the
objections thereto raised by Representative within thirty (30) days
of the date of receipt by Buyer of Representative's objections (or
such longer period as may be acceptable to Buyer and
Representative), Buyer and Representative shall submit the Proposed
Adjustments in dispute to the Arbitrating Accountants (as defined below) for
resolution.  The Arbitrating Accountants shall have no
authority (x) to decide any issues related to the Effective Time
Balance Sheet other than those issues expressly referred to them
for arbitration pursuant to the terms hereof, or (y) to determine
that any disputed Proposed Adjustment shall be made in excess
(negative or positive) of the amount originally proposed by Buyer.

               (d)  If the parties shall have submitted a dispute
to the Arbitrating Accountants, the parties shall instruct the
Arbitrating Accountants to resolve the disputed Proposed
Adjustments within thirty (30) business days after such adjustments
are submitted to them, and such resolution shall be final and
binding upon all parties hereto.  Upon such resolution, the
adjustments to the Effective Time Balance Sheet determined by the
Arbitrating Accountants shall be made and the Effective Time
Balance Sheet, as so adjusted, shall be final and binding upon all
parties.

               (e)  The fees and expenses of the Arbitrating
Accountants shall be paid by Buyer; provided that the portion of
such fees and expenses equal to the lesser of (i) 100% or (ii) the
percentage obtained by dividing (A) the aggregate dollar amount of
the adjustments to the Effective Time Balance Sheet determined
under Section 3.4(d), by (B) the aggregate dollar amount of the
disputed Proposed Adjustments shall be reimbursed to Buyer from the
Indemnification Escrow.

               (f)  The "Arbitrating Accountants" shall be Price
Waterhouse LLP (provided that Price Waterhouse LLP shall not
represent IMPRA or Buyer and shall not have represented such
persons within the three (3) prior years), or if Price Waterhouse
LLP shall not be available, a "Big Six" accounting firm that is
mutually agreed to by Buyer and Representative.

               (g)  Upon the Effective Time Balance Sheet
(including any adjustments) becoming final and binding on all
parties as set forth above, the Adjustment Amount shall be
determined by the Buyer.  Buyer's determination shall be final and
binding.  The Adjustment Amount shall equal the difference between
the Net Worth (as defined below) as shown on the Effective Time
Balance Sheet and (y) the Net Worth as shown on IMPRA's Balance
Sheet at June 30, 1996.  "Net Worth" shall equal the amount by
which assets exceed liabilities.  Buyer shall provide notice to the
Representative and all Shareholders of the Adjustment Amount and
final Purchase Price within two (2) business days of such amounts
becoming final.
<PAGE>
         3.5  Adjustment of Purchase Price3.5  Adjustment of Purchase Price.

X hereof shall survive beyond the Effective Time without limitation and (ii)
the representations and warranties of Buyer and IMPRA in this Agreement shall
survive beyond the Effective Time (the end of such period, the "Termination
Date") for six (6) months following the Effective Time solely for the purpose
of the Indemnification Escrow as described below.  

            (b)  Through the Indemnification Escrow described below, the
Surviving Corporation, Buyer, Buyer Sub and each of their officers,
directors, employees, agents, representatives and affiliates (collectively,
the "Indemnitees" and individually each an "Indemnitee") (subject to the
terms and conditions below) will be entitled to be indemnified and held
harmless by the Shareholders against and in respect of any claims, damages,
losses, costs, expenses, liabilities (absolute, accrued, contingent or
otherwise), and reasonable legal fees and expenses (collectively, "Losses")
incurred or suffered by any Indemnitee, directly or indirectly,
caused by or arising out of or related to any untruth, inaccuracy, error in,
or breach of, any representation or warranty of IMPRA contained in this
Agreement, when made or deemed to be made.  The rights of Indemnitees to
indemnification under this Section 10.1(b) shall be limited to,
and satisfied solely out of and to the extent of, the Indemnification Escrow
as it may be reduced or increased pursuant to Sections 3.2(d), 3.4(e) and
3.5, this Section 10.1 and the Escrow Agreement, and any Loss shall be
limited to those amounts for which the Indemnitee does not receive coverage
under applicable insurance policies, if any.  All indemnification requests of
Indemnitees hereunder shall be made by or through Buyer.

            (c)  By voting to approve this Agreement or by surrendering his
or her Certificate(s) evidencing IMPRA Shares at Closing, each Shareholder,
other than Shareholders who have perfected dissenter rights under the ABCA,
acknowledges and agrees that (i) the consideration to which such Shareholder
is entitled hereunder is subject to adjustment as contemplated in
Articles III and X, (ii) the Indemnification Escrow Payment and the Escrow
Adjustment shall be placed in the Indemnification Escrow provided for in an
Escrow Agreement to be entered into, as of the Effective Time, in the form of
Exhibit "G" attached hereto and (iii) the Escrow Agent shall be, and is
hereby, authorized from time to time to transfer all or any portion of the
amounts so deposited in satisfaction of the indemnity obligation and as
otherwise provided pursuant to Articles III and X and as contemplated in the
Escrow Agreement.  The Indemnitees agree to look solely to the
Indemnification Escrow for recourse in the event of a breach of any
representation or warranty of IMPRA contained in this Agreement and will not
look directly to any Shareholder or Shareholders for any indemnification
hereunder.

            (d)  If any Indemnitee shall have any liquidated claim of
indemnification pursuant to Section 10.1(b) above, it shall promptly request
that Buyer give written notice thereof to the Representative and the Escrow
Agent, including a brief description of the facts upon which such claim is
based and the amount thereof.  Any Indemnitee may also request that Buyer
provide written notice to the Representative and the Escrow Agent of any
unliquidated claim of indemnification pursuant to Section 10.1(b), including
a brief description of the facts upon which such claim is based and a demand
for a reserve amount to be created in respect of such claim. Any claim made
by any Indemnitee for Losses that are unliquidated shall not be paid, but
funds equal to such claim shall be held in the Indemnification Escrow until
such Losses are fully liquidated.  Notwithstanding the foregoing, no amount
will be delivered to an Indemnitee pursuant to a written claim notice (with
respect to either a liquidated or unliquidated claim) pursuant to Section 10.
1(b) above unless, and then only to the extent that, the aggregate amount of
Losses sustained by Indemnitees as a group and as to which written claim
notices have been given exceeds Two Hundred Fifty Thousand Dollars ($250,000)
(taking into account any reduction of prior noticed claims resulting from the
dispute resolution procedures of Section 10.2 below).

            (e)  If the Representative shall notify the Escrow Agent in
writing (within fifteen (15) days of delivery to the Escrow Agent by Buyer of
a written notice of claim for indemnification) of his objection to a claim of
indemnification or a demand for the creation of a reserve against the
Indemnification Escrow for any unliquidated claim (or the amount thereof),
the Escrow Agent shall hold the disputed amount of funds in the
Indemnification Escrow until the rights of the IMPRA Shareholders and the
Indemnitees with respect thereto have been agreed upon between the
Representative and the claiming Indemnitee.  In the event such an agreement is
reached, the claiming Indemnitee shall request Buyer to provide to the Escrow
Agent a written notice signed by the Representative in the form specified in
the Escrow Agreement.  If no such agreement has been reached, either the
Indemnitee or the Representative may, not earlier than thirty (30) days after
the date of the initial claim notice, submit the dispute to confidential,
binding arbitration in Phoenix, Arizona before a panel of three arbitrators,
one each to be selected by Buyer and the Representative, and the third to be
selected by the other two arbitrators, pursuant to the procedures and rules
for commercial arbitration of the American Arbitration Association. The
Escrow Agent may rely on the order or other determination of such
arbitrators.  If such arbitrators shall determine that any part of the
Indemnification Escrow is to be delivered to an Indemnitee or is to be set
aside in a reserve for any unliquidated claim, the Escrow Agent shall
promptly following receipt of a copy of such determination establish such
reserve or deliver to such Indemnitee the lesser of (i) the amount of the
claim or claims as awarded to the Indemnitee
to be satisfied, subject to the limitation set forth in paragraph (d) above,
or (ii) the entire amount remaining in the Indemnification Escrow.  Any
disputed amounts not awarded to the Indemnitee shall promptly be transferred
to the unreserved portion of the Indemnification Escrow.  Buyer and
the Representative shall bear their respective costs and expenses of any such
arbitration; provided that, the Representative shall be entitled to charge
the Indemnification Escrow for his reasonable costs and expenses as set forth
in the Escrow Agreement. 

            (f)  On and after the Termination Date, the Escrow Agent shall
distribute to the Shareholders on a pro rata basis all remaining unreserved
amounts in the Indemnification Escrow, less an amount equal to the dollar
amount of all claims pursuant to Section 10.1(c) that are still in process
in (i) that are then-payable liquidated claims, (ii) for which a reserve
established pursuant to paragraph (d) then exists, or (iii) that are still
in the process of resolution pursuant to Section 10.1 hereto.  No new claims
may be brought under this Section 10.1 after the Termination Date.

            (g)  After the Termination Date, (i) as each matter referred to
in Section 10.1(f) is resolved or otherwise concluded and (ii) as each
undisputed unliquidated claim which remains unliquidated as of the
Termination Date is liquidated, the Escrow Agent shall distribute to the
Shareholders their respective pro rata portion of the Escrow Fund then
determined by the Escrow Agent to be free of any rights of any Indemnitee,
and, when all such matters are resolved and such claims are liquidated, the
obligations under Section 10.1(b) hereof shall terminate.  The
Indemnification Escrow shall be terminated when all of the Escrow Fund in
the Indemnification Escrow shall have been disbursed in accordance with the
provisions hereof and the Escrow Agreement by the Escrow Agent.

            (h)  As of the Effective Time, the Shareholders shall, by virtue
of the approval of this Agreement by the requisite vote of the Shareholders,
be deemed, for themselves and their heirs and representatives and successors,
to have constituted and appointed, effective from the Effective Time, Harold
D. Green, as their agent and attorney-in-fact (the "Representative") to take
all action required or permitted under the Indemnification Escrow as provided
in the Escrow Agreement or herein with respect to the interests and rights of
the Shareholders.  In the event of the death, physical or mental incapacity
or resignation of the Representative a replacement Representative shall be
appointed as provided in the Escrow Agreement.

       In taking any action whatsoever hereunder, the Representative shall be
protected in relying upon any notice, paper or other document reasonably
believed by him to be genuine, or upon any evidence reasonably deemed by him
to be sufficient.  The Representative may consult with counsel in connection
with his duties hereunder and shall be fully protected in any act taken,
suffered or permitted by him in good faith or in accordance with the advice
of counsel.  The Representative shall not be liable to the Shareholders for
the performance of any act or the failure to act so long as he acted or
failed to act in good faith within what he reasonably believed to be the
scope of his authority and for a purpose which he reasonably believed to be
in the best interests of the Shareholders.

       10.2 Procedure10.2  Procedure.  In the event that at any time or from
time to time after the Effective Time a person indemnified under Section 10.1
or 10.3 (an "Indemnified Party") shall sustain a loss of any nature
whatsoever against which such Indemnified Party is indemnified under
this Agreement, such Indemnified Party shall notify the party hereto
obligated to provide such indemnification (the "Indemnitor") of any such
loss so sustained.  If Indemnitor is Buyer, Indemnitor shall within thirty
(30) days after transmittal of such notice pay to such Indemnified
Party the amount of such loss so sustained, subject to the right to contest
any claim which has not yet resulted in a loss, as herein provided.  If
Indemnitor is the Escrow Agent, payment shall be governed by the Escrow
Agreement.  The Indemnified Party shall promptly notify the Indemnitor
of the existence of any claim, demand, or other matter involving liabilities
to third parties to which the Indemnitor's indemnification obligations would
apply and shall give the Indemnitor (acting through the Representative if
Indemnitor is the Escrow Agent) a reasonable opportunity to defend
the same or prosecute such action to conclusion or settlement satisfactory
to the Indemnified Party at Indemnitor's own expense and with counsel of
Indemnitor's selection (who shall be approved by Indemnified Party, which
approval shall not be unreasonably withheld); provided that the Indemnified
Party shall at all times also have the right to fully participate in the
defense at its own expense.  If the Indemnitor shall, within a reasonable
time after said notice, fail to defend, the Indemnified Party shall have the
right, but not the obligation, to undertake the defense of, and to
compromise or settle (exercising reasonable business judgment) the claim or
other matter on behalf, for the account, and at the risk and expense of
Indemnitor.  Except as provided in the preceding sentence, the Indemnified
Party shall not compromise or settle the claim or other matter
without the prior written consent of the Indemnitor.  If the claim is one
that cannot by its nature be defended solely by the Indemnitor, the
Indemnified Party shall make available all information and assistance that
the Indemnitor may reasonably request; provided that any associated expenses
shall be paid by the Indemnitor.  If the Losses relate to a Loss or demand
asserted by a third party, the Indemnified Party and Indemnitor shall
jointly control the defense and settlement thereof and any settlement shall
require the prior written consent of both parties, which consent shall not be
unreasonably withheld.  

       10.3 Buyer's Indemnification10.3  Buyer's Indemnification.  Buyer
agrees to indemnify and hold Shareholders harmless from and against any and
all Losses which may accrue or be sustained by Shareholders arising out of
or as a result of (a) the conduct of the business or ownership of IMPRA or the
Surviving Corporation after the Effective Time, or (b) any of the warranties,
representations or covenants of Buyer contained in this Agreement being
incorrect, untrue or breached.

       10.4 Contest; Challenge10.4  Contest, Challenge.  If Indemnitor
contests or challenges any claim or action asserted against Indemnified Party
referred to in this Article, it shall do so at its own cost and expense (or
in the case of Escrow Agent, at the cost of the Indemnification Escrow),
holding Indemnified Party harmless from all costs, fees, expenses, debts,
liabilities and charges in connection with such contest; shall diligently
defend against any such claim; and shall hold Indemnified Party's business
and assets free and harmless from any attachment, execution,
judgment, lien or other legal process.

          NOW, THEREFORE, in consideration of the foregoing and
for other good and valuable consideration the receipt and

Hundred Thirty Nine Dollars ($143,178,539)" and substituting in
lieu thereof the following new phrase:

          the Representative shall cause to be delivered to Buyer
          a consolidated balance sheet of IMPRA as at the close
          of business at the Effective Time (the "Effective Time
          Balance Sheet") together with the related consolidated
          statements of income, shareholders' equity and cash
          flows for the period from June 30, 1996 to the

          inventory that representatives of Buyer may observe. 
          The Effective Time Balance Sheet and the Related
          Effective Time Statements shall be prepared in
          accordance with generally accepted accounting
          principles applied on a basis consistent with past
          practice, and the Effective Time Balance Sheet shall
          fairly present the assets and liabilities and financial
          condition of IMPRA at the Effective Time.  The
          reasonable fees and expenses of IMPRA's current
          independent accountants for their services pursuant to

          and the Surviving Corporation as may be reasonably
          necessary in connection with the preparation of the
          Effective Time Balance Sheet.

the Agreement and Plan of Merger shall be amended by adding to
the end thereof the following new sentence:

          respect to the Effective Time Balance Sheet
          (including any adjustments) and the Related
          Effective Time Statements."

              BARD ANNOUNCES ACQUISITION OF IMPRA

MURRAY HILL, NJ - September 16, 1996 - C. R. Bard, Inc. (NYSE-BCR)
announced today that it has completed the acquisition of Impra,
Inc.  Impra, headquartered in Tempe, AZ, is a leader in the
development, manufacturing and marketing of PTFE vascular grafts
used for blood vessel replacement surgery.  It offers more than 260
products to the vascular surgeon as a complete line, full service
supplier, with sales for the fiscal year ended June 30, 1996, of
$48.8 million.  In addition, Impra has several active R&D programs
in vascular graft and endovascular technology.  

"This acquisition will strengthen Bard's position in one of our key
surgical markets and help fuel top line growth for 1996 and
beyond," commented William H. Longfield, chairman and CEO.  "The
Impra acquisition fits very well with our strategy of strengthening
our franchise product areas.  We are particularly pleased with
Impra's R&D capability, especially in the potentially large market
opportunity for covering stents." 

Bard plans to consolidate its current vascular graft product line
with the Impra products and headquarter the new subsidiary, named
Bard Impra division, in the Tempe, AZ location.  John McDermott,
Impra's former chief operating officer, will manage Bard's new
consolidated operation as president of Bard Impra.

Bard paid $143.2 million for the common stock of Impra, making this
the largest acquisition in Bard's history.  Financing for the
acquisition was accomplished under Bard's new $350 million
commercial paper program which was initiated on Monday, September
9, 1996, with the sale of $100 million of commercial paper of
varying maturities.

C. R. Bard, Inc. headquartered in Murray Hill, NJ, is a leading
multinational developer, manufacturer and marketer of health care
products.
