ACUSON CORPORATION
NOTES TO CONDENSED CONSOLIDATED
FINANCIAL STATEMENTS

Note 1 - Interim Statements

       In  the  opinion  of   management,   the  unaudited   interim   condensed
consolidated  financial  statements include all adjustments,  which include only
normal recurring adjustments, necessary to summarize fairly Acuson Corporation's
(the "Company's") condensed consolidated financial position as of March 29, 1997
and its  condensed  consolidated  results of  operations  and cash flows for the
three-month  periods  ended  March 29, 1997 and March 30,  1996.  The results of
operations  for the  three  months  ended  March  29,  1997 are not  necessarily
indicative of the results to be expected for the entire year ending December 31,
1997.  Certain  information  reported in the prior year has been reclassified to
conform to the 1997 presentation.

       The  Company's  principle  accounting  policies  are  set  forth  in  the
financial  statements  for the year ended  December 31, 1996 and notes  thereto,
contained in the Company's  Annual Report filed with the Securities and Exchange
Commission.



Note 2 - Inventories

       The components of inventories were as follows (in thousands):

Note 3 - Short-Term Borrowings

     At March 29, 1997, the Company  temporarily  had two  revolving,  unsecured
credit  facilities in place.  The first unsecured credit agreement was for $50.0
million,  had  originated  in April 1995 and expired  March 31, 1997.  Under the
terms of this revolving,  unsecured credit agreement,  no compensating  balances
were  required and the  interest  rate was  determined  at the time of borrowing
based on the London  interbank  offered rate plus a margin,  or prime rate.  The
weighted average  borrowings were $16.3 million during the first quarter and the
weighted  average  interest rate was 6.0%. At March 29, 1997,  borrowings  under
this facility totalled $18.0 million and the effective rate was 6.3%.  Borrowing
under this facility was subject to certain debt covenants and the Company was in
compliance with those covenants.

     The new unsecured credit agreement is for $75.0 million and is in effect
through March 2000. Under the terms of the agreement, no compensating balances
are required and the interest rate is determined at the time of borrowing based
on the London interbank offered rate plus a margin, or prime rate. At March 29,
1997, there were no borrowings under this new facility. Subsequent to the
quarter end, the outstanding balance of $18.0 million was transferred from the
original agreement to the new agreement and the original agreement was
terminated. This new agreement is also subject to certain debt covenants and the
Company is in compliance with those covenants.

Note 4 - Legal Contingencies

       On October 27, 1994, the Company was sued in Ghent, Belgium, by Cormedica
NV, in connection with the Company's termination of its distributor relationship
with  Cormedica.  In the suit,  Cormedica  seeks  indemnities and damages in the
amount of  approximately  $2.5 million.  The Company intends to defend this suit
vigorously.  Management  believes that the ultimate  outcome of this matter will
not have a material adverse effect on the Company's financial condition.

Note 5 - Disclosure of the Impact That a Recently Issued Financial  Standard 
         Will Have on the Financial  Statements When Adopted in a Future Period

       In February 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 128, ("SFAS No. 128"), "Earnings
Per Share." SFAS No. 128 replaces the presentation of primary earnings per share
with a presentation of basic earnings per share, which excludes dilution. SFAS
No. 128 also requires dual presentation of basic and diluted earnings per share
on the face of the income statement. Diluted earnings per share is computed
similarly to fully diluted earnings per share pursuant to existing
pronouncements. SFAS No. 128 is effective for financial statements with periods
ending after December 15, 1997. This statement requires restatement of all 
prior-period earnings per share data presented. The Company anticipates adopting
SFAS No. 128 and this adoption will not have a material effect on its financial
statements. Calculated under SFAS No. 128, the basic earnings per share for the
first quarter is $0.20 and the diluted earnings per share is $0.19.

        In February 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 129, ("SFAS No. 129"),
"Disclosure of Information about Capital Structure", which will be adopted in
the fourth quarter of 1997. SFAS No. 129 requires companies to disclose certain
information about their capital structure. The Company anticipates this adoption
will not have a material effect on its financial statements.

ITEM 2
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS


Results of Operations

       The Company reported record revenues for the first quarter ended March
29, 1997, representing a 26.8% increase over the 1996 first quarter revenues.
Net revenues for the quarter ended March 29, 1997, were $107.6 million compared
with $84.8 million in the quarter ended March 30, 1996. The change in the first
quarter revenue resulted, in part, from shipments of the Sequoia(TM) ultrasound
systems and the Aspen(TM) ultrasound system which began in July and November
1996, respectively. Worldwide service revenue remained relatively stable at
$20.1 million compared with $20.5 million in the quarter ended March 30, 1996.
International revenue increased 6.9% to $37.1 million in the first quarter
compared with $34.8 million in the first quarter of 1996.

       Cost of sales increased as a percentage of net sales to 52.8% for 1997
compared with 48.1% for 1996. The percentage increase in 1997 was primarily a
reflection of the product mix and start-up and warranty costs on new product
installations.

       Selling, general and administrative costs were $29.0 million or 26.9% of
net sales in the quarter ended March 29, 1997, as compared with $26.8 million or
31.6% of net sales in the same period of the prior year. The spending increase
was primarily attributable to the investments in the Company's worldwide
distribution network.

       Product development spending for the first quarter of 1997 declined to
$13.2 million or 12.3% of net sales, compared with $16.4 million or 19.3% of net
sales in the first quarter of 1996. The $3.1 million decline in 1997 spending
represented a planned reduction following the new product introductions.
Although product development expenses have decreased from 1996, the Company
maintains a strong commitment to product development programs to develop
proprietary technologies.

       The provision for income taxes for the first quarter was $2.8 million
compared with $0.5 million in 1996. The effective tax rate for the three months
ended March 29, 1997, was 32.5% compared with 30.0% in the same period in the
prior year.

     In February 1997, the Financial Accounting Standards Board issued 
Statement of Financial Accounting Standards No. 128, ("SFAS No. 128"), "Earnings
Per Share." The Company will adopt adopting SFAS No. 128 and anticipates that
the adoption will not have a material effect on its financial statements. Please
see Note 5 to the condensed consolidated financial statements for further
discussion.

     In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 129, ("SFAS No. 129"), "Disclosure of
Information about Capital Structure." The Company anticipates that this adoption
will not have a material effect on its financial statements. Please see note 5
to the condensed consolidated financial statements for further discussion.

Liquidity and Capital Resources

       The Company's cash and cash equivalents balance increased $7.6 million
during the three months ended March 29, 1997, to $22.0 million. During the
quarter, the Company generated $1.8 million in cash from operations, as compared
with 1996 when operations used $1.5 million in cash, due primarily to improved
profitability and a reduction in inventory. Inventories provided $5.2 million
during the quarter from a reduction in inventories as a result of new product
introduction. Accounts receivable used $18.1 million in cash due primarily to
higher revenues.

       The Company's investing and financing activities for the three months
ended March 29, 1997, provided $6.0 million in cash. Included in the financing
activities for the three months of 1997, was $10.7 million raised through
employee participation in the Company's stock option and stock purchase plans,
which is offset by $7.8 million used for common

                                       6
<PAGE>
 
stock repurchases. In the same period a year ago, employee participation in the
Company's stock plans generated $3.4 million while the repurchases of common
stock used $9.9 million.

       In 1993, the Board of Directors authorized the repurchase of 4,000,000
shares of common stock, over an unspecified period of time, to reduce the
dilutive effect of the Company's stock plans. During the first quarter of 1997,
the Company repurchased 213,100 shares at a total cost of $5.7 million. As of
March 29, 1997, the Company had repurchased 3,914,000 shares toward the
4,000,000 share repurchase authorization at a cumulative cost of $55.9 million.
On October 15, 1996, the Board of Directors authorized the repurchase of an
additional 4,000,000 shares of common stock over an unspecified period of time.
There have been no purchases toward this authorization. As with all purchases
thus far, the Company intends to fund future purchases by utilizing the
Company's cash balances.

     Working capital in the first quarter increased over the corresponding 
prior-year period due primarily to increased cash flow from operations which
resulted in higher cash and accounts receivable. At March 29, 1997, the
Company's working capital totalled $128.6 million.

     At March 29, 1997, the Company temporarily had two revolving, unsecured
credit facilities in place. The first unsecured credit agreement was for $50.0
million, had originated in April 1995 and expired March 31, 1997. Under the
terms of this revolving, unsecured credit agreement, no compensating balances
were required and the interest rate was determined at the time of borrowing
based on the London interbank offered rate plus a margin, or prime rate. The
weighted average borrowings were $16.3 million during the first quarter and the
weighted average interest rate was 6.0%. At March 29, 1997, borrowings under
this facility totalled $18.0 million and the effective rate was 6.3%. Borrowing
under this facility was subject to certain debt covenants and the Company was in
compliance with those covenants.

     The new unsecured credit agreement is for $75.0 million and is in effect
through March 2000. Under the terms of the agreement, no compensating balances
are required and the interest rate is determined at the time of borrowing based
on the London interbank offered rate plus a margin, or prime rate. At March 29,
1997, there were no borrowings under this new facility. Subsequent to the
quarter end, the outstanding balance of $18.0 million was transferred from the
original agreement to the new agreement and the original agreement was
terminated. This new agreement is also subject to certain debt covenants and the
Company is in compliance with those covenants.

       Based on its current operating plan, the Company believes that the
liquidity provided by its existing cash, cash generated from operations, and the
borrowing arrangements described above will be sufficient to meet the Company's
operating and capital requirements for fiscal 1997.

Investment Risks

       The Management's Discussion and Analysis of Financial Condition and
Results of Operations ("MD&A") section in this report contains forward-looking
statements regarding the Company and its products. These forward-looking
statements are based on current expectations and the Company assumes no
obligation to update this information. The Company's actual results could differ
materially from these discussed in this document. In evaluating the forward-
looking statements contained in this document, prospective investors and
shareholders should carefully consider the factors set forth below.

       The Sequoia and Aspen ultrasound platforms raise several risk factors.
Specifically, the success of these products depends on actual and perceived
levels of product performance in a clinical environment; market acceptance of
the products and their pricing; competitor responses including competing
products and pricing, intellectual property allegations and product positioning
counterstrategies, and timely completion of future product capabilities. The
realizable value of inventory and/or fixed assets for all of the Company's
products is dependent on the timing and success of product introduction to the
marketplace and market acceptance.

       In addition, while the Company believes that there has recently been a
positive momentum in the worldwide ultrasound market, there can be no assurance
that this momentum will continue. Also, the Company's business is subject to
further risks from developments in other imaging modalities and changes in
government regulation of the marketing of ultrasound equipment.

                           ---------------                              
     Percentage on the daily average Unused Commitment for the period beginning
     on the date of this Agreement and ending on the Maturity Date.  (The
     Commitment Fee Percentage shall be determined as provided in the Pricing

              ------------------------                                  
     (whether such prepayment is an optional prepayment under Subparagraph

     amount of all Loans then outstanding exceeds the lesser of the Total

     due and payable under this Agreement or the other Credit Documents and

     from Borrower at least one (1) Business Day prior to the date on which any
     payment is due to the Lenders hereunder that Borrower will not make such
     payment in full, Agent shall be entitled to assume that Borrower has made
     or will make such payment in full to Agent on such date and Agent may, in
     reliance upon such assumption, cause to be paid to the Lenders on such due
     date an amount equal to the amount then due such Lenders.  If and to the
     extent Borrower shall not have so made such payment in full to Agent, each
     such Lender shall repay to Agent forthwith on demand such amount
     distributed to such Lender together with interest thereon, for each day
     from the date such amount is distributed to such Lender until the date such
     Lender repays such amount to Agent, at (i) the Federal Funds Rate for the
     first three (3) days and (ii) the per annum rate applicable to Base Rate
     Loans thereafter.  A certificate of Agent submitted to any Lender with

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

          (a) Lender Funding and Disbursement to Borrower.  Each Lender shall,
              -------------------------------------------                     
     before 2:00 p.m. on the date of each Borrowing, make available to Agent at
     Agent's office specified in Paragraph 8.01, in same day or immediately
                                 --------------                            
     available funds, such Lender's Proportionate Share of such Borrowing.
     After Agent's receipt of such funds and upon satisfaction of the applicable
     conditions set forth in Section III, Agent shall promptly disburse such
                             -----------                                    
     funds to Borrower in same day or immediately available funds.  Unless
     otherwise directed by Borrower, Agent shall disburse the proceeds of each
     Borrowing by disbursement to the account or accounts specified in the
     applicable Notice of Borrowing.

          (b) Lender Failure to Fund.  Unless Agent shall have received notice
              ----------------------                                          
     from a Lender prior to the date of any Borrowing that such Lender will not
     make available to Agent such Lender's Proportionate Share of such
     Borrowing, Agent shall be entitled to assume that such Lender has made or
     will make such portion available to Agent on the date of such Borrowing in
     accordance with Subparagraph 2.12(a), and 
                     --------------------      


                                      27
<PAGE>
 
     Agent may on such date, in reliance upon such assumption, disburse or
     otherwise credit to Borrower a corresponding amount. If any Lender does not
     make the amount of its Proportionate Share of any Borrowing available to
     Agent on or prior to the date of such Borrowing, such Lender shall pay to
     Agent, on demand, interest which shall accrue on such amount from the date
     of such Borrowing until such amount is paid to Agent at rates equal to (i)
     the daily Federal Funds Rate during the period from the date of such
     Borrowing through the third Business Day thereafter and (ii) the rate
     applicable to Base Rate Loans thereafter. A certificate of Agent submitted
     to any Lender with respect to any amounts owing under this Subparagraph
                                                                ------------
     2.12(b) shall be conclusive absent manifest error. If the amount of any
     -------    
     Lender's Proportionate Share of any Borrowing is not paid to Agent by such
     Lender within three (3) Business Days after the date of such Borrowing,
     Borrower shall repay such amount to Agent, on demand, together with
     interest thereon, for each day from the date such amount was disbursed to
     Borrower until the date such amount is repaid to Agent, at the interest
     rate applicable at the time to the Loans comprising such Borrowing.

          (c) Lenders' Obligations Several.  The failure of any Lender to make
              ----------------------------                                    
     the Loan to be made by it as part of any Borrowing shall not relieve any
     other Lender of its obligation hereunder to make its Loan on the date of
     such Borrowing, but no Lender shall be obligated in any way to make any
     Loan which another Lender has failed or refused to make or otherwise be in
     any way responsible for the failure or refusal of any other Lender to make
     any Loan required to be made by such other Lender on the date of any
     Borrowing.

     2.13.  Pro Rata Treatment.
            ------------------ 

          (a) Borrowings, Commitment Reductions, Etc.  Except as otherwise
              ---------------------------------------                     
     provided herein:

                    (i) Each Borrowing and reduction of the Total Commitment
          shall be made or shared among the Lenders pro rata according to their
          respective Proportionate Shares;

                   (ii) Each payment of principal of Loans in any Borrowing
          shall be shared among the Lenders which made or funded the Loans in
          such Borrowing pro rata according to the respective unpaid principal
          amounts of such Loans so made or funded by such Lenders;

                  (iii) Each payment of interest on Loans in any Borrowing
          shall be shared among the Lenders which made or funded the Loans in
          such Borrowing pro rata according to (A) the respective unpaid
          principal 

                                      28
<PAGE>
 
          amounts of such Loans so made or funded by such Lenders and (B) the
          dates on which such Lenders so made or funded such Loans;

                   (iv) Each payment of Commitment Fees shall be shared among
          the Lenders (except for Defaulting Lenders) pro rata according to (A)
          their respective Proportionate Shares and (B) in the case of each
          Lender which becomes a Lender hereunder after the date hereof, the
          date upon which such Lender so became a Lender;

                    (v) Each payment of interest (other than interest on Loans)
          shall be shared among the Lenders and Agent owed the amount upon which
          such interest accrues pro rata according to (A) the respective amounts
          so owed such Lenders and Agent and (B) the dates on which such amounts
          became owing to such Lenders and Agent; and

                   (vi) All other payments under this Agreement and the other
          Credit Documents shall be for the benefit of the Person or Persons
          specified.

          (b) Sharing of Payments, Etc.  If any Lender shall obtain any payment
              -------------------------                                        
     (whether voluntary, involuntary, through the exercise of any right of
     setoff, or otherwise) on account of Loans owed to it in excess of its
     ratable share of payments on account of such Loans obtained by all Lenders
     entitled to such payments, such Lender shall forthwith purchase from the
     other Lenders such participations in the Loans as shall be necessary to
     cause such purchasing Lender to share the excess payment ratably with each
     of them; provided, however, that if all or any portion of such excess
              --------  -------                                           
     payment is thereafter recovered from such purchasing Lender, such purchase
     shall be rescinded and each other Lender shall repay to the purchasing
     Lender the purchase price to the extent of such recovery together with an
     amount equal to such other Lender's ratable share (according to the
     proportion of (i) the amount of such other Lender's required repayment to
     (ii) the total amount so recovered from the purchasing Lender) of any
     interest or other amount paid or payable by the purchasing Lender in
     respect of the total amount so recovered.  Borrower agrees that any Lender
     so purchasing a participation from another Lender pursuant to this
                                                                       
     Subparagraph 2.13(b) may, to the fullest extent permitted by law, exercise
     --------------------                                                      
     all its rights of payment (including the right of setoff) with respect to
     such participation as fully as if such Lender were the direct creditor of
     Borrower in the amount of such participation.

     2.14.  Change of Circumstances.
            ----------------------- 

          (a) Inability to Determine Rates.  If, on or before the first day of
              ----------------------------                                    
     any Interest Period for any LIBOR Loan, Agent shall determine that (i) the
     LIBO Rate for such Interest Period cannot be adequately and reasonably
     determined due to the unavailability of funds in or other circumstances
     affecting the London interbank market or (ii) the rate of interest for such
     Loan does not adequately and fairly reflect the cost to any Lender of
     making or maintaining such LIBOR Loan, Agent shall immediately give notice
     of such condition to Borrower and the other Lenders.  After the giving of
     any such notice and until Agent shall otherwise notify Borrower that the
     circumstances giving rise to such condition no longer exist, Borrower's
     right to request the making of, and the Lenders' obligations to make LIBOR
     Loans shall be suspended.  Any LIBOR Loans outstanding at the commencement
     of any such suspension shall be converted at the end of the then current
     Interest Period for such LIBOR Loans into Base Rate Loans unless such
     suspension has then ended.

          (b) Illegality.  If, after the date of this Agreement, the adoption of
              ----------                                                        
     any Governmental Rule, any change in any Governmental Rule or the
     application or requirements thereof (whether such change occurs in
     accordance with the terms of such Governmental Rule as enacted, as a result
     of amendment or otherwise), any change in the interpretation or
     administration of any Governmental Rule by any Governmental Authority, or
     compliance by any Lender with any request or directive (whether or not
     having the force of law) of any Governmental Authority (a "Change of Law")
                                                                -------------  
     shall make it unlawful or impossible for any Lender to make or maintain any
     LIBOR Loan, such Lender shall immediately notify Agent and Borrower of such
     Change of Law.  Upon receipt of such notice, (i) Borrower's right to
     request the making of, and such Lender's obligation to make LIBOR Loans
     shall be terminated, and (ii) Borrower shall, at the request of such
     Lender, either (A) repay any such then outstanding LIBOR Loans at the end
     of the current Interest Period for such LIBOR Loans or (B) immediately
     repay any such LIBOR Loans if such Lender shall notify Borrower that such
     Lender may not lawfully continue to fund and maintain such LIBOR Loans.
     Any prepayment of LIBOR Loans made pursuant to the preceding sentence prior
     to the last day of an Interest Period for such LIBOR Loans shall be deemed
     a prepayment thereof for purposes of Paragraph 2.16.  After any Lender
     notifies Agent and Borrower of such a Change of Law and until such Lender
     notifies Agent and Borrower that it is no longer unlawful or impossible for
     such Lender to make or maintain a LIBOR Loan, all Loans of such Lender
     shall be Base Rate Loans.

          (c) Increased Costs.  If, after the date of this Agreement, any Change
              ---------------                                                   
     of Law:

                    (i) Shall subject any Lender to any tax, duty or other
          charge with respect to any LIBOR Loan, or shall change the basis of
          taxation of payments by Borrower to any Lender on such a LIBOR Loan or
          in respect to such a LIBOR Loan under this Agreement (except for
          changes in the rate of taxation on the overall net income of any
          Lender imposed by its jurisdiction of incorporation or the
          jurisdiction in which its principal executive office is located); or

                   (ii) Shall impose, modify or hold applicable any reserve
          (excluding any Reserve Requirement or other reserve to the extent
          included in the calculation of the LIBO Rate for any Loans), special
          deposit or similar requirement against assets held by, deposits or
          other liabilities in or for the account of, advances or loans by, or
          any other acquisition of funds by any Lender for any LIBOR Loan; or

                  (iii) Shall impose on any Lender any other condition related
          to any LIBOR Loan or such Lender's Commitment;

          And the effect of any of the foregoing is to increase the cost to such
     Lender of making, renewing, or maintaining any such LIBOR Loan or its
     Commitment or to reduce any amount receivable by such Lender hereunder;
     then Borrower shall from time to time, within five (5) Business Days after
     demand by such Lender, pay to such Lender additional amounts sufficient to
     reimburse such Lender for such increased costs or to compensate such Lender
     for such reduced amounts.  A certificate as to the amount of such increased
     costs or reduced amounts, submitted by such Lender to Borrower shall, in
     the absence of manifest error, be conclusive and binding on Borrower for
     all purposes.  The obligations of Borrower under this Subparagraph 2.14(c)
                                                           --------------------
     shall survive the payment and performance of the Obligations and the
     termination of this Agreement.

          (d) Capital Requirements.  If, after the date of this Agreement, any
              --------------------                                            
     Lender determines that (i) any Change of Law affects the amount of capital
     required or expected to be maintained by such Lender or any Person
     controlling such Lender (a "Capital Adequacy Requirement") and (ii) the
                                 ----------------------------               
     amount of capital maintained by such Lender or such Person which is
     attributable to or based upon the Loans, the Commitments or this Agreement
     must be increased as a result of such Capital Adequacy Requirement (taking
     into account such Lender's or such Person's policies with respect to
     capital adequacy), Borrower shall pay to such Lender or such 

                                      31
<PAGE>
 
     Person, within five (5) Business Days after demand by such Lender, such
     amounts as such Lender or such Person shall determine are necessary to
     compensate such Lender or such Person for the increased costs to such
     Lender or such Person of such increased capital. A certificate of any
     Lender setting forth in reasonable detail the computation of any such
     increased costs, delivered by such Lender to Borrower shall, in the absence
     of manifest error, be conclusive and binding on Borrower for all purposes.
     The obligations of Borrower under this Subparagraph 2.14(d) shall survive
                                            --------------------
     the payment and performance of the Obligations and the termination of this
     Agreement.

          (e) Mitigation.  Any Lender which becomes aware of (i) any Change of
              ----------                                                      
     Law which will make it unlawful or impossible for such Lender to make or
     maintain any LIBOR Loan or (ii) any Change of Law or other event or
     condition which will obligate Borrower to pay any amount pursuant to
                                                                         
     Subparagraph 2.14(c) or Subparagraph 2.14(d) shall notify Borrower and
     --------------------    --------------------                          
     Agent thereof as promptly as practical.  If any Lender has given notice of
     any such Change of Law or other event or condition and thereafter becomes
     aware that such Change of Law or other event or condition has ceased to
     exist, such Lender shall notify Borrower and Agent thereof as promptly as
     practical.  Each Lender affected by any Change of Law which makes it
     unlawful or impossible for such Lender to make or maintain any LIBOR Loan
     or to which Borrower is obligated to pay any amount pursuant to
                                                                    
     Subparagraph 2.14(c) or Subparagraph 2.14(d) shall use reasonable
     --------------------    --------------------                     
     commercial efforts (including changing the jurisdiction of its Applicable
     Lending Office) to avoid the effect of such Change of Law or to avoid or
     materially reduce any amounts which Borrower is obligated to pay pursuant
     to Subparagraph 2.14(c) or Subparagraph 2.14(d) if, in the reasonable
        --------------------    --------------------                      
     opinion of such Lender, such efforts would not be disadvantageous to such
     Lender or contrary to such Lender's normal banking practices.

     2.15.  Taxes on Payments.
            ----------------- 

          (a) Payments Free of Taxes.  All payments made by Borrower under this
              ----------------------                                           
     Agreement and the other Credit Documents shall be made free and clear of,
     and without deduction or withholding for or on account of, any present or
     future income, stamp or other taxes, levies, imposts, duties, charges,
     fees, deductions or withholdings, now or hereafter imposed, levied,
     collected, withheld or assessed by any Governmental Authority (except net
     income taxes and franchise taxes in lieu of net income taxes imposed on
     Agent or any Lender by its jurisdiction of incorporation or the
     jurisdiction in which its Applicable Lending Office is located) (all such
     non-excluded taxes, levies, imposts, duties, charges, fees, deductions and
     withholdings being hereinafter called "Taxes").  Subject to Subparagraphs
                                            -----                -------------
     2.15(c) and 2.15(d), if any Taxes are required to be withheld from any
     -------------------                                                   
     amounts payable to Agent or any Lender hereunder or under the other Credit
     Documents, the amounts so payable to Agent or such Lender shall be
     increased to the extent necessary to yield to Agent or such Lender (after
     payment of all Taxes) interest or any such other amounts payable hereunder
     at the rates or in the amounts specified in this Agreement and the other
     Credit Documents.  Whenever any Taxes are payable by Borrower, as promptly
     as possible thereafter, Borrower shall send to Agent for its own account or
     for the account of such Lender, as the case may be, a certified copy of an
     original official receipt received by Borrower showing payment thereof.  If
     Borrower fails to pay any Taxes when due to the appropriate taxing
     authority or fails to remit to Agent the required receipts or other
     required documentary evidence, Borrower shall indemnify Agent and the
     Lenders for any incremental taxes, interest or penalties that may become
     payable by Agent or any Lender as a result of any such failure.  The
     obligations of Borrower under this Subparagraph 2.15(a) shall survive the
                                        --------------------                  
     payment and performance of the Obligations and the termination of this
     Agreement.

          (b) Withholding Exemption Certificates, Etc.  If Agent or any Lender
              ---------------------------------------                         
     is not organized under the laws of the United States of America or a state
     thereof, such Person agrees as set forth below in this Subparagraph
                                                            ------------
     2.15(b).

                    (i) If any such Person is a "bank" within the meaning of
          Section 881(c)(3)(A) of the IRC, it shall, no later than the Closing
          Date (or, in the case of a Lender which becomes a Lender hereunder
          pursuant to Subparagraph 8.05(c) after the Closing Date, the date upon
                      --------------------                                      
          which such Lender so becomes a Lender hereunder) deliver to Borrower
          and Agent two (2) accurate and complete signed originals of IRS Form
          4224 or any 

                                      33
<PAGE>
 
          successor thereto ("Form 4224"), or two accurate and complete signed
          originals of IRS Form 1001 or any successor thereto ("Form 1001"), as
          appropriate, in each case indicating that such Person is, on the date
          of delivery thereof, entitled to receive payments of principal,
          interest and fees under this Agreement free from withholding of United
          States Federal income tax. If at any time such Person makes any
          changes necessitating a new Form 4224 or Form 1001, it shall, within
          thirty (30) days after such change becomes effective, deliver to
          Borrower and Agent in replacement for, or in addition to, the forms
          previously delivered by it hereunder, two accurate and complete signed
          originals of Form 4224, or two accurate and complete signed originals
          of Form 1001, as appropriate, in each case indicating that such Person
          is, on the date of delivery thereof, entitled to receive payments of
          principal, interest and fees under this Agreement free from
          withholding of United States Federal income tax.

                   (ii) If any such Person is not a "bank" within the meaning of
          Section 881(c)(3)(A) of the IRC, it shall, no later than the Closing
          Date (or, in the case of a Lender which becomes a Lender hereunder
          pursuant to Subparagraph 8.05(c) after the Closing Date, the date upon

          which such Lender so becomes a Lender hereunder) deliver to Borrower

          W-8 or any successor thereto ("Form W-8") certifying to such Person's
          legal entitlement (assuming compliance by Borrower with the terms of
          this Agreement) to an exemption whereby such Person is on the date of
          delivery thereof entitled to receive payments of principal, interest
          and fees under this Agreement free from withholding of United States
          Federal income tax.  If at any time any such Person makes any changes
          necessitating a new Form W-8, it shall, within thirty (30) days after
          such change becomes effective, deliver to Borrower and Agent in
          replacement for, or in addition to, the forms previously delivered by
          it hereunder, two accurate and complete signed originals of Form W-8
          certifying to such Person's legal entitlement (assuming compliance by
          Borrower with the terms of this Agreement) to an exemption whereby
          such Person is on the date of delivery thereof entitled to receive
          payments of principal, interest and fees under this Agreement free
          from withholding of United States Federal income tax.

                  (iii)  Each such Person shall, before or within thirty (30)
          days after the occurrence of any event (including the passing of time
          but excluding any event mentioned in clause (i) or (ii) above)
                                               ------------------       
          requiring a 

                                      34
<PAGE>
 
          change in or renewal of the most recent Form 4224, Form 1001 or Form
          W-8 previously delivered by such Person, deliver to Borrower and Agent
          two accurate and complete original signed copies of Form 4224, Form
          1001 or Form W-8 in replacement for the forms previously delivered by
          such Person.

                   (iv) Each such Person shall, promptly upon the reasonable
          request of Agent, deliver to Agent such other forms or similar
          documentation as may be required from time to time by any applicable
          Governmental Rule in order to establish such Lender's tax status for
          withholding purposes.

          (c) Non-Compliance, Etc.  Borrower will not be required to pay any
              -------------------                                           
     additional amounts in respect of United States Federal income tax pursuant
     to Subparagraph 2.15(a) to Agent or any Lender subject to Subparagraph
        --------------------                                   ------------
     2.15(b) if:
     -------    

                    (i) The obligation to pay such additional amounts would not
          have arisen but for a failure by such Person to comply with its
          obligations under Subparagraph 2.15(b); or
                            --------------------    

                   (ii) Such Person is not entitled to exemption from deduction
          or withholding of United States Federal income tax for payments by
          Borrower to such Person hereunder for the account of its Applicable
          Lending Office for any reason other than a Change of Law after the
          date of delivery by such Person of Form 4224, Form 1001 or Form W-8,
          as the case may be.

          (d) Mitigation.  If Agent or any Lender claims any additional amounts
              ----------                                                       
     to be payable to it pursuant to this Paragraph 2.15, such Person shall use
                                          --------------                       
     reasonable commercial efforts to file any certificate or document requested
     in writing by Borrower (including without limitation copies of Internal
     Revenue Service Form 1001 (or successor forms) reflecting a reduced rate of
     withholding) or to change the jurisdiction of its Applicable Lending Office
     if the making of such a filing or such change in the jurisdiction of its
     Applicable Lending Office would avoid the need for or materially reduce the
     amount of any such additional amounts which may thereafter accrue and if,
     in the reasonable opinion of such Person, in the case of a change in the
     jurisdiction of its Applicable Lending Office, such change would not be
     disadvantageous to such Person or contrary to such Person's normal banking
     practices.

          (e) Tax Returns.  Nothing contained in this Paragraph 2.15 shall
              -----------                             --------------      
     require Agent or any Lender to make available any of its tax returns (or
     any other information relating to its taxes which it deems to be
     confidential).

     2.16.  Funding Loss Indemnification.  If Borrower shall (a) repay or
            ----------------------------                                 
prepay any LIBOR Loan on any day other than the last day of an Interest Period
therefor (whether a scheduled payment, an optional prepayment, a mandatory
prepayment or a payment upon acceleration or otherwise) or (b) fail to borrow
any LIBOR Loan for which a Notice of Borrowing has been delivered to Agent
(whether as a result of the failure to satisfy any applicable conditions or
otherwise), Borrower shall, upon demand by any Lender, reimburse such Lender for
and hold such Lender harmless from all costs and losses incurred by such Lender
as a result of such repayment, prepayment or failure.  Borrower understands that
such costs and losses may include losses incurred by a Lender as a result of
funding and other contracts entered into by such Lender to fund a LIBOR Loan.
Each Lender demanding payment under this Paragraph 2.16 shall deliver to
                                         --------------                 
Borrower, with a copy to Agent, a certificate setting forth the amount of costs
and losses for which demand is made, which certificate shall set forth in
reasonable detail the calculation of the amount demanded.  Such a certificate so
delivered to Borrower shall constitute prima facie evidence of such costs and
                                       ----- -----                           
losses.  The obligations of Borrower under this Paragraph 2.16 shall survive the
                                                --------------                  
payment and performance of the Obligations and the termination of this
Agreement.

     2.17.  Replacement of Lenders.  If any Lender shall (a) become a
            ----------------------                                   
Defaulting Lender, (b) suspend its obligation to make or maintain LIBOR Loans
pursuant to Subparagraph 2.14(b) for a reason which is not applicable to any
            --------------------                                            
other Lender or (c) demand any payment under Subparagraph 2.14(c), 2.14(d) or
                                             --------------------------------
2.15(a) for a reason which is not applicable to any other Lender, then Agent may
- -------                                                                         
(or shall, upon the written request of Borrower if no Event of Default has
occurred and is continuing) replace such Lender (the "affected Lender"), or
cause such affected Lender to be replaced, with another lender (the "replacement
Lender") satisfying the requirements of an Assignee Lender under Subparagraph
                                                                 ------------
8.05(c), by having the affected Lender sell and assign all of its rights and
- -------                                                                     
obligations under this Agreement and the other Credit Documents to the
replacement Lender pursuant to Subparagraph 8.05(c); provided, however, that if
                               --------------------  --------  -------         
Borrower seeks to exercise such right, it must give Agent written notice of its
intent to do so within thirty (30) days after it first knows or should have
known of the occurrence of the event or events giving rise to such right and
must effect such replacement within sixty (60) days of giving such notice.
Neither Agent nor any Lender shall have any obligation to identify or locate a
replacement Lender for Borrower.  Upon receipt by any affected Lender of a
written notice from Agent stating that Agent is exercising the replacement right
set forth in this Paragraph 2.17, such affected Lender shall sell and assign all
                  --------------                                                
of its rights and obligations under this Agreement and the other Credit
Documents to the replacement Lender pursuant to an Assignment Agreement and
                                                                           
Subparagraph 8.05(c) for a purchase price equal to the sum of the principal
- --------------------                                                       
amount of the affected Lender's Loans so sold and assigned, all accrued and
unpaid interest thereon and its ratable share of all fees to which it is
entitled.

     2.18.  Maturity Date Extensions.  Borrower may, at any time, request
            ------------------------                                     
the Lenders to extend the Maturity Date then in effect for an additional one-
year period by delivering a written request to Agent.  Agent shall promptly
deliver to each Lender a copy of any such extension request received by Agent.
If a Lender, in its sole and absolute discretion, consents to any Extension
Request, such Lender shall so notify Agent in writing not later than any time
specified by Agent.  Any failure by any Lender so to notify Agent shall be
deemed a denial thereof.  (Borrower acknowledges and agrees that no Lender has
promised, either expressly or impliedly, or has any obligation or commitment, to
consent to such a request at any time.)  If all Lenders consent to an extension
request, Agent shall so notify Borrower and the Lenders and shall prepare an
amendment to reflect the requested extension.  If no Lender or less than all
Lenders shall consent to an extension request, Agent shall so notify Borrower
and the Lenders, and the Maturity Date then in effect shall remain in effect.

obligation to deliver such item.


SECTION IV.    REPRESENTATIONS AND WARRANTIES.
               ------------------------------ 

     4.01.  Borrower's Representations and Warranties.  In order to induce
            -----------------------------------------                     
Agent and the Lenders to enter into this Agreement, Borrower hereby represents
and warranties to Agent and the Lenders as follows:

          (a) Due Incorporation, Qualification, etc.  Each of Borrower and
              --------------------------------------

              ---------                                                         
     each Credit Document executed, or to be executed, by Borrower and the
     consummation of the transactions contemplated thereby (i) are within the
     power of Borrower and (ii) have been duly authorized by all necessary
     actions on the part of Borrower.

          (c) Enforceability.  Each Credit Document executed, or to be executed,
              --------------

     application relating to or affecting the enforcement of creditors' rights
     generally and general principles of equity.

          (d) Non-Contravention.  The execution and delivery by Borrower of the
              -----------------                                                
     Credit Documents executed by Borrower and the performance and consummation
     of the transactions contemplated thereby do not (i) violate any Requirement
     of Law applicable to Borrower; (ii) violate any provision of, or result in
     the breach or the acceleration of, or entitle any other Person to

     any Contractual Obligation of Borrower; or (iii) result in the creation or
     imposition of any Lien (or the obligation to create or impose any Lien)
     upon any property, asset or revenue of Borrower (except such Liens as may
     be created in favor of Agent pursuant to this Agreement or the other Credit
     Documents).

          (e) Approvals.  No consent, approval, order or 
              ---------

     authorization of, or registration, declaration or filing with, any
     Governmental Authority or other Person (including, without limitation, the
     shareholders of any Person) is required in connection with the execution
     and delivery of the Credit Documents executed by Borrower and the
     performance and consummation of the transactions contemplated thereby.

          (f) No Violation or Default.  Neither Borrower nor any of its
              -----------------------                                  
     Subsidiaries is in violation of or in default with respect to (i) any
     Requirement of Law applicable to such Person; (ii) any Contractual
     Obligation of such Person (nor is there any waiver in effect which, if not
     in effect, would result in such a violation or default), where, in each
     case, such violation or default is reasonably likely to have a Material
     Adverse Effect.  Without limiting the generality of the foregoing, except
     as set forth in the Disclosure Letter, neither Borrower nor any of its
     Subsidiaries (A) has violated any Environmental Laws, (B) has any liability
     under any Environmental Laws or (C) has received notice or other
     communication of an investigation or is under investigation by any
     Governmental Authority having authority to enforce Environmental Laws,
     where such violation, liability or investigation is reasonably likely to
     have a Material Adverse Effect.  No Default has occurred and is continuing.

          (g) Litigation.  Except as set forth in the Disclosure Letter, no
              ----------                                                   
     actions (including, without limitation, derivative actions), suits,
     proceedings or investigations are pending or, to the knowledge of Borrower,
     threatened against Borrower or any of its Subsidiaries at law or in equity
     in any court or before any other Governmental Authority which (i) is
     reasonably likely (alone or in the aggregate) to have a Material Adverse
     Effect or (ii) seeks to enjoin, either directly or indirectly, the
     execution, delivery or performance by Borrower of the Credit Documents or
     the transactions contemplated thereby.

          (h) Title; Possession under Leases.  Borrower and its Subsidiaries own
              ------------------------------                                    
     and have good and marketable title, or a valid leasehold interest in, all
     their respective properties and assets as reflected in the most recent
     Financial Statements delivered to Agent (except those assets and properties
     disposed of in the ordinary course of business or otherwise in compliance
     with this Agreement since the date of such Financial Statements) and all
     respective assets and properties acquired by Borrower and its Subsidiaries
     since such date (except those disposed of in the ordinary course of
     business or otherwise in compliance with this Agreement).  Such assets and
     properties are subject to no Lien, except for Permitted Liens.  Each of
     Borrower and its Subsidiaries has complied with all material obligations
     under all material leases to which it is a party and all such leases 

                                      40
<PAGE>
 
     are in full force and effect. Each of Borrower and its Subsidiaries enjoys
     peaceful and undisturbed possession under such leases, except where any
     failure to enjoy such possession (alone or in the aggregate with other such
     failures) is not reasonably likely to have a Material Adverse Effect.

          (i) Financial Statements.  The Financial Statements of Borrower and
              --------------------                                           
     its Subsidiaries which have been delivered to Agent, (i) are in accordance
     with the books and records of Borrower and its Subsidiaries, which have
     been maintained in accordance with good business practice; (ii) have been
     prepared in conformity with GAAP; and (iii) fairly present the financial
     conditions and results of operations of Borrower and its Subsidiaries as of
     the date thereof and for the period covered thereby.  As of the date of,
     and except as disclosed in the audited Financial Statements dated December
     31, 1996 furnished by Borrower to Agent prior to the date hereof and in the
     Financial Statements delivered to Agent pursuant to clause (i) or (ii) of
                                                         ---------------------
     Subparagraph 5.01(a), neither Borrower nor any of its Subsidiaries has any
     --------------------                                                      
     Contingent Obligations, liability for taxes or other outstanding
     obligations which are material in the aggregate.

          (j) No Agreements to Sell Assets; Etc.  Neither Borrower nor any of
              ---------------------------------                              
     its Subsidiaries has any legal obligation, absolute or contingent, to any
     Person to sell the assets of Borrower or any of its Subsidiaries (other
     than sales in the ordinary course of business), or to effect any merger,
     consolidation or other reorganization of Borrower or any of its
     Subsidiaries or to enter into any agreement with respect thereto.

          (k)  Employee Benefit Plans.
               ---------------------- 

                    (i) Based on the latest valuation of each Employee Benefit
          Plan that either Borrower or any ERISA Affiliate maintains or
          contributes to, or has any obligation under (which valuation occurred
          within twelve months of the date of this representation), the
          aggregate benefit liabilities of such plan within the meaning of (S)
          4001 of ERISA did not exceed the aggregate value of the assets of such
          plan.  Neither Borrower nor any ERISA Affiliate has any liability with
          respect to any post-retirement benefit under any Employee Benefit Plan
          which is a welfare plan (as defined in section 3(1) of ERISA), other
          than liability for health plan continuation coverage described in Part
          6 of Title I(B) of ERISA, which liability for health plan contribution
          coverage is not reasonably likely to have a Material Adverse Effect.

                   (ii) Each Employee Benefit Plan complies, in both 

                                      41

          form and operation, in all material respects, with its terms, ERISA
          and the IRC, and no condition exists or event has occurred with
          respect to any such plan which, individually or in the aggregate, is
          reasonably likely to have a Material Adverse Effect. Each Employee
          Benefit Plan, related trust agreement, arrangement and commitment of
          Borrower or any ERISA Affiliate is legally valid and binding and in
          full force and effect. No Employee Benefit Plan is being audited or
          investigated by any government agency or is subject to any pending or
          threatened claim or suit (other than routine benefits claims). Neither
          Borrower nor any ERISA Affiliate nor any fiduciary of any Employee
          Benefit Plan has engaged in a prohibited transaction under section 406
          of ERISA or section 4975 of the IRC which, individually or in the
          aggregate, is reasonably likely to have a Material Adverse Effect.

                  (iii)  Neither Borrower nor any ERISA Affiliate contributes to
          or has any material contingent obligations to any Multiemployer Plan.
          Neither Borrower nor any ERISA Affiliate has incurred any material
          liability (including secondary liability) to any Multiemployer Plan as
          a result of a complete or partial withdrawal from such Multiemployer
          Plan under Section 4201 of ERISA or as a result of a sale of assets
          described in Section 4204 of ERISA.  Neither Borrower nor any ERISA
          Affiliate has been notified that any Multiemployer Plan is in
          reorganization or insolvent under and within the meaning of Section
          4241 or Section 4245 of ERISA or that any Multiemployer Plan intends
          to terminate or has been terminated under Section 4041A of ERISA.

          (l) Other Regulations.  Borrower is not subject to regulation under
              -----------------                                              
     the Investment Company Act of 1940, the Public utility Holding Company Act
     of 1935, the Federal Power Act, the Interstate Commerce Act, any state
     public utilities code or to any other Governmental Rule limiting its
     ability to incur indebtedness.

          (m) Patent and Other Rights.  Borrower and its Subsidiaries own or
              -----------------------

     trademarks, trade names, trade secrets, service marks, copyrights and all
     rights with respect thereto, which are required to conduct their businesses
     as now conducted, except where any failure so to own, license or have the
     right to license without consent (alone or in the aggregate with other such
     failures) is not reasonably likely to have a Material Adverse Effect.

                                      42
<PAGE>
 
          (n) Governmental Charges.  Borrower and its Subsidiaries have filed or
              --------------------                                              
     caused to be filed all tax returns which are required to be filed by them.
     Borrower and its Subsidiaries have paid, or made provision for the payment
     of, all taxes and other Governmental Charges which have or may have become
     due pursuant to said returns or otherwise and all other indebtedness,
     except such Governmental Charges or indebtedness, if any, which are being
     contested in good faith and as to which adequate reserves (determined in
     accordance with GAAP) have been provided or which are not reasonably likely
     to have a Material Adverse Effect if unpaid.

          (o) Margin Stock.  Borrower owns no Margin Stock which, in the
              ------------                                              
     aggregate, would constitute a substantial part of the assets of Borrower,
     and no proceeds of any Loan will be used to purchase or carry, directly or
     indirectly, any Margin Stock or to extend credit, directly or indirectly,
     to any Person for the purpose of purchasing or carrying any Margin Stock.

          (p) Subsidiaries, etc.  Set forth in Schedule 4.01(p) (as supplemented
              ------------------               ----------------                 
     by Borrower from time to time in a written notice to Agent) is a complete
     list of all of Borrower's Subsidiaries, the jurisdiction of incorporation
     of each, the classes of Equity Securities of each and the percentages of
     shares of each such class owned directly or indirectly by Borrower.  Except
     for such Subsidiaries, Borrower has no other Subsidiaries, is not a partner
     in any partnership or a joint venturer in any joint venture.

          (q) Solvency, Etc.  Borrower is Solvent and, after the execution and
              --------------                                                  
     delivery of the Credit Documents and the consummation of the transactions
     contemplated thereby, will be Solvent.

          (r) Catastrophic Events.  Neither Borrower nor any of its Subsidiaries
              -------------------                                               
     and none of their properties is affected by any fire, explosion, accident,
     strike, lockout or other labor dispute, drought, storm, hail, earthquake,
     embargo, act of God or other casualty that is reasonably likely to have a
     Material Adverse Effect.  There are no disputes presently subject to
     grievance procedure, arbitration or litigation under any of the collective
     bargaining agreements, employment contracts or employee welfare or
     incentive plans to which Borrower or any of its Subsidiaries is a party,
     and there are no strikes, lockouts, work stoppages or slowdowns, or, to the
     best knowledge of Borrower, jurisdictional disputes or organizing
     activities occurring or threatened which alone or in the aggregate are
     reasonably likely to have a Material Adverse Effect.

          (s) No Material Adverse Effect.  No event has occurred 
              --------------------------                               
                                      43

     and no condition exists which is reasonably likely to have a Material
     Adverse Effect.

          (t) Accuracy of Information Furnished.  None of the Credit Documents
              ---------------------------------                               
     and none of the other certificates, statements or information furnished to
     Agent or any Lender by or on behalf of Borrower or any of its Subsidiaries
     in connection with the Credit Documents or the transactions contemplated
     thereby contains or will contain any untrue statement of a material fact or
     omits or will omit to state a material fact necessary to make the
     statements therein, in light of the circumstances under which they were
     made, not misleading.

          4.02.  Reaffirmation.  Borrower shall be deemed to have reaffirmed,
                 -------------

for representations and warranties expressly made as of a specified date, which
shall be true as of such date).

<PAGE>
 
          7.01.  Appointment, Powers and Immunities.  Each Lender hereby
                 ----------------------------------                     
appoints and authorizes Agent to act as its agent hereunder and under the other
Credit Documents with such powers as are expressly delegated to Agent by the
terms of this Agreement and the other Credit Documents, together with such other
powers as are reasonably incidental thereto.  Agent shall not have any duties or
responsibilities except those expressly set forth in this Agreement or in any
other Credit Document, be a trustee for any Lender or have any fiduciary duty to
any Lender.  Notwithstanding anything to the contrary contained herein Agent
shall not be required to take any action which is contrary to this Agreement or
any other Credit Document or any applicable Governmental Rule.  Neither Agent
nor any Lender shall be responsible to any other Lender for any recitals,
statements, representations or warranties made by Borrower or any of its
Subsidiaries contained in this Agreement or in any other Credit Document, for
the value, validity, effectiveness, genuineness, enforceability or sufficiency
of this Agreement or any other Credit Document or for any failure by Borrower or
any of its Subsidiaries to perform their respective obligations hereunder or
thereunder.  Agent may employ agents and attorneys-in-fact and shall not be
responsible to any Lender for the negligence or misconduct of any such agents or
attorneys-in-fact selected by it with reasonable care.  Neither Agent nor any of
its directors, officers, employees, agents or advisors shall be responsible to
any Lender for any action taken or omitted to be taken by it or them hereunder
or under any other Credit Document or in connection herewith or therewith,
except for its or their own gross negligence or willful misconduct.  Except as
otherwise provided under this Agreement, Agent shall take such action with
respect to the Credit Documents as shall be directed by the Required Lenders.

          7.02.  Reliance by Agent.  Agent shall be entitled to rely upon any
                 -----------------                                           
certificate, notice or other document (including any cable, telegram, facsimile
or telex) believed by it in good faith to be genuine and correct and to have
been signed or sent by or on behalf of the proper Person or Persons, and upon
advice and statements of legal counsel, independent accountants and other
experts selected by Agent with reasonable care.  As to any other matters not
expressly provided for by this Agreement, Agent shall not be required to take
any action or exercise any discretion, but shall be required to act or to
refrain from acting upon instructions of the Required Lenders and shall in all
cases be fully protected by the Lenders in acting, or in refraining from acting,
hereunder or under any other Credit Document in accordance with the instructions
of the Required Lenders, and such instructions of the Required Lenders and any
action taken or failure to act pursuant thereto shall be binding on all of the
Lenders.

          7.03.  Defaults.  Agent shall not be deemed to have 
                 --------                                                 


                                      59
<PAGE>
 
knowledge or notice of the occurrence of any Default unless Agent has received a
written notice from a Lender or Borrower, referring to this Agreement,
describing such Default and stating that such notice is a "Notice of Default".
If Agent receives such a notice of the occurrence of a Default, Agent shall give
prompt notice thereof to the Lenders. Agent shall take such action with respect
to such Default as shall be reasonably directed by the Required Lenders;
provided, however, that until Agent shall have received such directions, Agent
- --------  -------
may (but shall not be obligated to) take such action, or refrain from taking
such action, with respect to such Default as it shall deem advisable in the best
interest of the Lenders.

          7.04.  Indemnification.  Without limiting the Obligations of Borrower
                 ---------------                                               
hereunder, each Lender agrees to indemnify Agent, ratably in accordance with
their Proportionate Shares, for any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever which may at any time be imposed on, incurred
by or asserted against Agent in any way relating to or arising out of this
Agreement or any documents contemplated by or referred to herein or therein or
the transactions contemplated hereby or thereby or the enforcement of any of the
terms hereof or thereof; provided, however, that no Lender shall be liable for
                         --------  -------                                    
any of the foregoing to the extent they arise from Agent's gross negligence or
willful misconduct.  Agent shall be fully justified in refusing to take or in
continuing to take any action hereunder unless it shall first be indemnified to
its satisfaction by the Lenders against any and all liability and expense which
may be incurred by it by reason of taking or continuing to take any such action.
The obligations of each Lender under this Paragraph 7.04 shall survive the
                                          --------------                  
payment and performance of the Obligations, the termination of this Agreement
and any Lender ceasing to be a party to this Agreement (with respect to events
which occurred prior to the time such Lender ceased to be a Lender hereunder).

          7.05.  Non-Reliance.  Each Lender represents that it has,
                 ------------                                      
independently and without reliance on Agent, or any other Lender, and based on
such documents and information as it has deemed appropriate, made its own
appraisal of the business, prospects, management, financial condition and
affairs of Borrower and the Subsidiaries and its own decision to enter into this
Agreement and agrees that it will, independently and without reliance upon Agent
or any other Lender, and based on such documents and information as it shall
deem appropriate at the time, continue to make its own appraisals and decisions
in taking or not taking action under this Agreement.  Neither Agent nor any of
its affiliates nor any of their respective directors, officers, employees,
agents or advisors shall (a) be required to keep any Lender informed as to the
performance or observance by Borrower or any of its Subsidiaries of the
obligations under this Agreement or any other document referred to or provided
for herein or to make inquiry of, or to inspect the properties or 


                                      60
<PAGE>
 
books of Borrower or any of its Subsidiaries; (b) have any duty or
responsibility to provide any Lender with any credit or other information
concerning Borrower or any of its Subsidiaries which may come into the
possession of Agent, except for notices, reports and other documents and
information expressly required to be furnished to the Lenders by Agent
hereunder; or (c) be responsible to any Lender for (i) any recital, statement,
representation or warranty made by Borrower or any officer, employee or agent of
Borrower in this Agreement or in any of the other Credit Documents, (ii) the
value, validity, effectiveness, genuineness, enforceability or sufficiency of
this Agreement or any Credit Document, (iii) the value or sufficiency of any
collateral or the validity or perfection of any of the liens or security
interests intended to be created by the Credit Documents, or (iv) any failure by
Borrower to perform its obligations under this Agreement or any other Credit
Document.

          7.06.  Resignation or Removal of Agent.  Agent may resign at any time
                 -------------------------------                               
by giving thirty (30) days prior written notice thereof to Borrower and the
Lenders, and Agent may be removed at any time with or without cause by the
Required Lenders.  Upon any such resignation or removal, the Required Lenders
shall have the right to appoint a successor Agent, which Agent, if not a Lender,
shall be reasonably acceptable to Borrower; provided, however, that Borrower
                                            --------  -------               
shall have no right to approve a successor Agent if a Default has occurred and
is continuing.  Upon the acceptance of any appointment as Agent hereunder by a
successor Agent, such successor Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring Agent,
and the retiring Agent shall be discharged from the duties and obligations
thereafter arising hereunder.  After any retiring Agent's resignation or removal
hereunder as Agent, the provisions of this Section VII shall continue in effect
                                           -----------                         
for its benefit in respect of any actions taken or omitted to be taken by it
while it was acting as Agent.

          7.07.  Authorization.  Agent is hereby authorized by the Lenders to
                 -------------                                               
execute, deliver and perform, each of the Credit Documents to which Agent is or
is intended to be a party and each Lender agrees to be bound by all of the
agreements of Agent contained in the Credit Documents.

          7.08.  Agent in its Individual Capacity.  Agent and its affiliates may
                 --------------------------------                               
make loans to, accept deposits from and generally engage in any kind of banking
or other business with Borrower and its Subsidiaries and affiliates as though
Agent were not Agent hereunder.  With respect to Loans, if any, made by Agent in
its capacity as a Lender, Agent in its capacity as a Lender shall have the same
rights and powers under this Agreement and the other Credit Documents as any
other Lender and may exercise the same as though it were not Agent, and the
terms "Lender" or "Lenders" shall include Agent in its capacity as a Lender.

Each Notice of Borrowing and Notice of Interest Period Selection shall be given
by Borrower to Agent's office located at the address referred to above during
Agent's normal business hours; provided, however, that any such notice received
                               --------  -------                               
by Agent after 1:00 p.m. on any Business Day shall be deemed received by Agent
on the next Business Day.  In any case where this Agreement authorizes notices,
requests, demands or other communications by Borrower to Agent or any Lender to
be made by telephone or facsimile, Agent or any Lender may conclusively presume
that anyone purporting to be a person designated in any incumbency certificate
or other similar document received by Agent or a Lender is such a person.

          8.02.  Expenses.  Borrower shall pay on demand, whether or not any
                 --------                                                   
Loan is made hereunder, (a) all reasonable out-of-pocket fees and expenses,
including reasonable out-of-pocket  attorneys' fees and expenses, incurred by
Agent in connection with the preparation, negotiation, execution and delivery
of, and the exercise of its duties under, this Agreement and the other Credit
Documents, and the preparation, negotiation, execution and delivery of
amendments and waivers hereunder and thereunder and (b) all reasonable out-of-
pocket fees and expenses, including reasonable out-of-pocket attorneys' fees and
expenses, incurred by Agent and the Lenders in the enforcement or attempted
enforcement of any of the Obligations or in preserving any of Agent's or the
Lenders' rights and remedies (including, without limitation, all such fees and
expenses incurred in connection with any "workout" or restructuring affecting
the Credit Documents or the Obligations or any bankruptcy or similar proceeding
involving Borrower or any of its Subsidiaries).  The obligations of Borrower
under this Paragraph 8.02 shall survive the payment and performance of the
           --------------                                                 
Obligations and the termination of this Agreement.

          8.03.  Indemnification.  To the fullest extent permitted by law,
                 ---------------                                          
Borrower agrees to protect, indemnify, defend and hold harmless Agent, the
Lenders and their Affiliates and their 


                                      63
<PAGE>
 
respective directors, officers, employees, agents and advisors ("Indemnitee")
                                                                 ----------
from and against any and all liabilities, losses, damages or expenses of any
kind or nature and from any suits, claims or demands (including in respect of or
for reasonable attorney's fees and other expenses) arising on account of or in
connection with any matter or thing or action or failure to act by Indemnitee,
or any of them, arising out of or relating to the Credit Documents or any
transaction contemplated thereby, including without limitation any use by
Borrower of any proceeds of the Loans, except to the extent such liability
arises from the willful misconduct or gross negligence of such Indemnitee. Upon
receiving knowledge of any suit, claim or demand asserted by a third party that
Agent or any Lender believes is covered by this indemnity, Agent or such Lender
shall give Borrower notice of the matter and an opportunity to defend it, at
Borrower's sole cost and expense, with legal counsel satisfactory to Agent or
such Lender, as the case may be. Agent or such Lender may also require Borrower
to defend the matter. Any failure or delay of Agent or any Lender to notify
Borrower of any such suit, claim or demand shall not relieve Borrower of its
obligations under this Paragraph 8.03 but shall reduce such obligations to the
                       --------------
extent of any increase in those obligations caused solely by any such failure or
delay which is unreasonable. The obligations of Borrower under this Paragraph
                                                                    ---------
8.03 shall survive the payment and performance of the Obligations and the
- ----
termination of this Agreement.

          8.04.  Waivers; Amendments.  Any term, covenant, agreement or
                 -------------------                                   
condition of this Agreement or any other Credit Document may be amended or
waived, and any consent under this Agreement or any other Credit Document may be
given, if such amendment, waiver or consent is in writing and is signed by
Borrower and the Required Lenders (or Agent on behalf of the Required Lenders
with the written approval of the Required Lenders); provided, however that:
                                                    --------  -------      

          (a)  Any amendment, waiver or consent which would (i) increase the
     Total Commitment, (ii) extend the Maturity Date, (iii) reduce the principal
     of or interest on any Loan or any fees or other amounts payable for the
     account of the Lenders hereunder, (iv) extend any scheduled principal,
     interest or fee payment date, (v) amend this Paragraph 8.04, or (vi) amend
                                                  --------------               
     the definition of Required Lenders, must be in writing and signed or
     approved in writing by all Lenders;

          (b)  Any amendment, waiver or consent which increases or decreases the
     Proportionate Share of any Lender must be in writing and signed by such
     Lender; and

          (c)  Any amendment, waiver or consent which affects the rights or
     obligations of Agent must be in writing and signed by Agent.


                                      64

No failure or delay by Agent or any Lender in exercising any right under this
Agreement or any other Credit Document shall operate as a waiver thereof or of
any other right hereunder or thereunder nor shall any single or partial exercise
of any such right preclude any other further exercise thereof or of any other
right hereunder or thereunder.  Unless otherwise specified in such waiver or
consent, a waiver or consent given hereunder shall be effective only in the
specific instance and for the specific purpose for which given.

          8.05.  Successors and Assigns.
                 ---------------------- 

          (a) Binding Effect.  This Agreement and the other Credit Documents
              --------------                                                
     shall be binding upon and inure to the benefit of Borrower, the Lenders,
     Agent, all future holders of the Notes and their respective successors and
     permitted assigns, except that Borrower may not assign or transfer any of
     its rights or obligations under any Credit Document without the prior
     written consent of Agent and each Lender.  All references in this Agreement
     to any Person shall be deemed to include all successors and assigns of such
     Person.

          (b) Participations.  Any Lender may at any time sell to one or more
              --------------                                                 
     banks or other financial institutions ("Participants") participating
                                             ------------                
     interests in any Loan owing to such Lender, any Note held by such Lender,
     any Commitment of such Lender or any other interest of such Lender under
     this Agreement and the other Credit Documents.  In the event of any such
     sale by a Lender of participating interests, such Lender's obligations
     under this Agreement shall remain unchanged, such Lender shall remain
     solely responsible for the performance thereof, such Lender shall remain
     the holder of its Notes for all purposes under this Agreement and Borrower
     and Agent shall continue to deal solely and directly with such Lender in
     connection with such Lender's rights and obligations under this Agreement.
     Any agreement pursuant to which any such sale is effected may require the
     selling Lender to obtain the consent of the Participant in order for such
     Lender to agree in writing to any amendment, waiver or consent of a type
     specified in clause (i), (ii), (iii) or (iv) of Subparagraph 8.04(a) but
                  -------------------------------------------------------    
     may not otherwise require the selling Lender to obtain the consent of such
     Participant to any other amendment, waiver or consent hereunder.  Borrower
     agrees that if amounts outstanding under this Agreement and the other
     Credit Documents are not paid when due (whether upon acceleration or
     otherwise), each Participant shall, to the fullest extent permitted by law,
     be deemed to have the right of setoff in respect of its participating
     interest in amounts owing under this Agreement and any other Credit
     Documents to the same extent as if the amount of its participating interest
     were owing directly to it as a Lender under this Agreement or any other
     Credit Documents; provided, however, that (i) no Participant shall exercise
                       --------  -------                                        
     any rights under this sentence without the consent of Agent, (ii) no
     Participant shall have any rights under this sentence which are greater
     than those of the selling Lender and (iii) such rights of setoff shall be
     subject to the obligation of such Participant to share the payment so
     obtained with all of the Lenders as provided in Subparagraph 2.13(b).
                                                     --------------------  
     Borrower also agrees that any Lender which has transferred any
     participating interest in its Commitment or Loans shall, notwithstanding
     any such transfer, be entitled to the full benefits accorded such Lender
     under Paragraph 
           ---------

                                      66
<PAGE>
 
     2.14, Paragraph 2.15, and Paragraph 2.16, as if such Lender
     ----  --------------      --------------
     had not made such transfer.

          (c) Assignments.  Any Lender may, at any time, sell and assign to any
              -----------                                                      
     Lender or any Eligible Assignee (individually, an "Assignee Lender") all or
                                                        ---------------         
     a portion of its rights and obligations under this Agreement and the other
     Credit Documents (such a sale and assignment to be referred to herein as an
     "Assignment") pursuant to an assignment agreement in the form of Exhibit E
      ----------                                                      ---------
     (an "Assignment Agreement"), executed by each Assignee Lender and such
          --------------------                                             
     assignor Lender (an "Assignor Lender") and delivered to Agent for its
                          ---------------                                 
     acceptance and recording in the Register; provided, however, that:
                                               --------  -------       

                    (i)  Without the written consent of Agent and, if no Default
          has occurred and is continuing, Borrower (which consent of Agent and
          Borrower shall not be unreasonably withheld), no Lender may make any
          Assignment to any Assignee Lender which is not, immediately prior to
          such Assignment, a Lender hereunder or an Affiliate thereof; or

                   (ii)  Without the written consent of Agent and, if no Default
          has occurred and is continuing, Borrower (which consent of Agent and
          Borrower shall not be unreasonably withheld), no Lender may make any
          Assignment to any Assignee Lender if, after giving effect to such
          Assignment, the Commitment of such Lender or such Assignee Lender
          would be less than Ten Million Dollars ($10,000,000) (except that a
          Lender may make an Assignment which reduces its Commitment to zero
          without the written consent of Borrower and Agent); or

                  (iii)  Without the written consent of Agent and, if no Default
          has occurred and is continuing, Borrower (which consent of Agent and
          Borrower shall not be unreasonably withheld), no Lender may make any
          Assignment which does not assign and delegate an equal pro rata
          interest in such Lender's Loans, Commitment and all other rights,
          duties and obligations of such Lender under this Agreement and the
          other Credit Documents.

          Upon such execution, delivery, acceptance and recording of each
     Assignment Agreement, from and after the Assignment Effective Date
     determined pursuant to such Assignment Agreement, (A) each  Assignee Lender
     thereunder shall be a Lender hereunder with a Proportionate Share as set
     forth on Attachment 1 to such Assignment Agreement (under the caption
              -----------------------------------------                   
     "Proportionate Share After Assignment") and shall have the rights, duties
     and obligations of such a Lender under this Agreement and the other Credit
     Documents, and (B) the 


                                      67
<PAGE>
 
     Assignor Lender thereunder shall be a Lender with a Proportionate Share as
     set forth on Attachment 1 to such Assignment Agreement (under the caption
                  -----------------------------------------
     "Proportionate Share After Assignment"), or, if the Proportionate Share of
     the Assignor Lender has been reduced to 0%, the Assignor Lender shall cease
     to be a Lender and to have any obligation to make any Loan; provided,
                                                                 --------
     however, that any such Assignor Lender which ceases to be a Lender shall
     -------
     continue to be entitled to the benefits of any provision of this Agreement
     which by its terms survives the termination of this Agreement. Each
     Assignment Agreement shall be deemed to amend Schedule I to the extent, and
                                                   ----------
     only to the extent, necessary to reflect the addition of each Assignee
     Lender, the deletion of each Assignor Lender which reduces its
     Proportionate Share to 0% and the resulting adjustment of Proportionate
     Shares arising from the purchase by each Assignee Lender of all or a
     portion of the rights and obligations of an Assignor Lender under this
     Agreement and the other Credit Documents. On or prior to the Assignment
     Effective Date determined pursuant to each Assignment Agreement, Borrower,
     at its own expense, shall execute and deliver to Agent, in exchange for the
     surrendered Note of the Assignor Lender thereunder, a new Note to the order
     of each Assignee Lender thereunder (with each new Note to be in an amount
     equal to the Commitment assumed by such Assignee Lender) and, if the
     Assignor Lender is continuing as a Lender hereunder, a new Note to the
     order of the Assignor Lender (with the new Note to be in an amount equal to
     the Commitment retained by it). Each such new Note shall be dated the
     Closing Date and otherwise in the form of the Note replaced thereby. The
     Notes surrendered by the Assignor Lender shall be returned by Agent to
     Borrower marked "replaced". Each Assignee Lender which was not previously a
     Lender hereunder and which is not incorporated under the laws of the United
     States of America or a state thereof shall, within three (3) Business Days
     of becoming a Lender, deliver to Borrower and Agent two duly completed
     copies of United States Internal Revenue Service Form 1001 or 4224 (or
     successor applicable form), as the case may be, certifying in each case
     that such Lender is entitled to receive payments under this Agreement
     without deduction or withholding of any United States federal income taxes.

          (d) Register.  Agent shall maintain at its address referred to in
              --------                                                     
     Paragraph 8.01 a copy of each Assignment Agreement delivered to it and a
     --------------                                                          
     register (the "Register") for the recordation of the names and addresses of
                    --------                                                    
     the Lenders and the Proportionate Shares of each Lender from time to time.
     The entries in the Register shall be conclusive in the absence of manifest
     error, and Borrower, Agent and the Lenders may treat each Person whose name
     is recorded in the Register as the owner of the Loans recorded therein for
     all proposes of this Agreement.  The Register 


                                      68
<PAGE>
 
     shall be available for inspection by Borrower or any Lender at any
     reasonable time and from time to time upon reasonable prior notice.

          (e) Registration.  Upon its receipt of an Assignment Agreement
              ------------                                              
     executed by an Assignor Lender and an Assignee Lender (and, to the extent
     required by Subparagraph 8.05(c), by Borrower and Agent) together with
                 --------------------                                      
     payment to Agent by Assignor Lender of a registration and processing fee of
     $2,500, Agent shall (i) promptly accept such Assignment Agreement and (ii)
     on the "Assignment Effective Date" determined pursuant thereto record the

fix (i) one or more Exercise Dates with respect to such Purchase Period, one of
which shall be on the last day of such Purchase Period, (ii) the Applicable
Discount with respect to such Purchase Period, (iii) the Compensation with
respect to such Purchase Period and (iv) the maximum number of shares that may
be 

                                      -3-
<PAGE>
 
purchased by any Participant on any Exercise Date during such Purchase Period
(the "Per-Participant Limit"). In addition, the Plan Administrator may, in its
discretion, fix a maximum number of shares of Common Stock that may be purchased
by all Participants in the aggregate during such Purchase Period and/or on any
given Exercise Date therein. Once fixed, the Exercise Date or Dates, the
Applicable Discount, the Compensation, the Per-Participant Limit and any
aggregate share purchase limits with respect to a given Purchase Period may not
be changed, except upon the occurrence of a Corporate Transaction as provided in
paragraph 18(b).

       (c)  A Participant shall be granted a separate purchase right for each
Purchase Period in which he/she participates. The purchase right shall be
granted on the first day of the Purchase Period and shall be automatically
exercised in successive installments on each Exercise Date during the Purchase
Period.

       (d)  If the Plan Administrator establishes overlapping Purchase Periods,
the Plan Administrator may, in its discretion, permit Participants to
participate in more than one Purchase Period at a time.

       (e)  If on the Trading Day following any Exercise Date in a Purchase
Period the Fair Market Value of the Common Stock is less than the Fair Market
Value of the Common Stock on the first day of such Purchase Period (after taking
into account any adjustment during the Purchase Period pursuant to paragraph
18(a)), the Plan Administrator may, in its discretion, provide that the Purchase
Period shall be terminated and that all Participants therein shall be enrolled
in a new Purchase Period, other than any such Participants who are not eligible
to participate in the Plan on that date or who have elected to terminate
participation in the Plan. Any such new Purchase Period (a "Replacement Purchase
Period") shall be established by the Plan Administrator pursuant to paragraph
4(a) and shall commence on the date that such previous Purchase Period is
terminated. The Plan Administrator shall fix one or more Exercise Dates, the
Applicable Discount, the Compensation and the Per-Participant Limit, and may fix
aggregate share purchase limits, pursuant to paragraph 4(b) with respect to such
Replacement Purchase Period.

       (f)  Except as specifically provided herein, the acquisition of Common
Stock through participation in the Plan for any Purchase Period shall neither
limit nor require the acquisition of Common Stock by a Participant in any
subsequent Purchase Period.

       5.   Participation.
            -------------

       (a)  An eligible Employee may become a Participant in the Plan by
completing a subscription agreement authorizing payroll deductions in a form
designated by the Company and filing it with the Company's payroll office prior
to the Enrollment Date for the Purchase Period in which such participation will
commence in accordance with the filing deadline established by the Company. Such
agreement will remain effective under subsequent Purchase Periods unless and
until such Employee files a new agreement or terminates his/her participation in
the Plan in accordance with paragraph 6(c), provided that such Employee must
file a new subscription agreement to enroll in any Purchase Period that overlaps
with a Purchase Period in which such Employee has previously enrolled.

       (b)  Payroll deductions for a Participant shall commence with the first
payroll following the Enrollment Date and shall end on the last complete payroll
period during the Purchase Period, unless sooner terminated by the Participant
as provided in paragraph 10.

       6.   Payroll Deductions.
            ------------------

       (a)  At the time a Participant files his/her subscription agreement,
he/she shall elect to have payroll deductions made on each pay day during the
Purchase Period in an amount from three to 

                                      -4-
<PAGE>
 
fifteen percent (in whole percentages only) of the Compensation which he/she
receives on each such pay day.

       (b)  All payroll deductions made for a Participant shall be credited to
his/her account under the Plan. A Participant may not make any additional
payments into such account.

       (c)  A Participant may discontinue his/her participation in the Plan as
provided in paragraph 10. A Participant's subscription agreement shall remain in
effect for successive Purchase Periods unless and until such Participant files a
new agreement or terminates his/her participation in the Plan as provided in
paragraph 10. The Plan Administrator may, in its discretion, permit Participants
to amend their subscription agreements to increase and/or decrease the rate of
their payroll deductions during any given Purchase Period.

       (d)  Notwithstanding the foregoing, to the extent necessary to comply
with Section 423(b)(8) of the Code and paragraph 3(b) herein, a Participant's
payroll deductions may be decreased to 0% at such time during any Purchase
Period which is scheduled to end during the current calendar year (the "Current
Purchase Period") that the aggregate of all payroll deductions which were
previously used to purchase stock under the Plan in any other Purchase Period
that ended or that will end during that calendar year plus all payroll
deductions accumulated with respect to the Current Purchase Period equal the
maximum amount permitted under Section 423 of the Code. Payroll deductions shall
recommence at the rate provided in such Participant's subscription agreement at
the beginning of the first Purchase Period which is scheduled to end in the
following calendar year, unless terminated by the Participant as provided in
paragraph 10.

       7.   Grant of Purchase Right. On the first day of each Purchase Period,
            -----------------------
each Participant in such Purchase Period shall be granted the right to purchase
on each Exercise Date of such Purchase Period (at the applicable Purchase Price)
up to a number of shares of Common Stock determined by dividing such
Participant's payroll deductions accumulated prior to such Exercise Date and
retained in the Participant's account as of the Exercise Date by the applicable
Purchase Price; provided that such purchase shall be subject to the limitations
set forth in paragraphs 3(b), 4(b), 6(d), 8(b) and 12(a) hereof. Exercise of the
purchase right shall occur as provided in paragraph 8, unless the Participant
has withdrawn from the Plan pursuant to paragraph 10, and the purchase right, to
the extent not exercised, shall expire on the last day of the Purchase Period.

       8.   Exercise of Purchase Right.
            --------------------------

       (a)  Unless a Participant withdraws from the Plan as provided in
paragraph 10 below, his/her right to purchase shares will be exercised
automatically on each Exercise Date, and the maximum number of full shares
subject to such right shall be purchased for such Participant at the applicable
Purchase Price with the accumulated payroll deductions in his/her account. No
fractional shares will be purchased; any payroll deductions accumulated in a
Participant's account which are not sufficient to purchase a full share shall be
carried over to the next Exercise Date under the Plan or returned to the
Participant, provided that, if the next Exercise Date falls within a new
Purchase Period, such payroll deductions shall be carried over to such Exercise
Date only if the Participant participates in such new Purchase Period. Any
amount remaining in a Participant's account at the close of any Exercise Date
caused by anything other than a surplus due to fractional shares (including the
accumulated payroll deductions in any Participant's account as of any Exercise
Date that are in excess of the amount needed to purchase the maximum number of
full shares which may be purchased by such Participant based on the limitations
in paragraphs 3(b), 4(b), 6(d), 8(b) and 12(a) hereof) shall be refunded to the
Participant in cash as soon as practicable and shall not be carried over to the
next Exercise Date. During a Participant's lifetime, a Participant's right to
purchase shares hereunder is exercisable only by him/her.

       (b)  If, on a given Exercise Date, the aggregate purchase of shares upon
the exercise in full of all purchase rights would exceed the aggregate share
purchase limit, if any, fixed by the Plan 

                                      -5-
<PAGE>
 
Administrator pursuant to paragraph 4(b) with respect to the applicable Purchase
Period, the Company shall make a pro-rata allocation of the available shares in
as nearly uniform a manner as shall be practicable and as it shall determine to
be equitable.

       9.   Delivery. The Company shall arrange the delivery to each Participant
            --------
of a certificate representing the shares of Common Stock purchased upon exercise
of his/her purchase right based upon instructions provided to the Company by the
Participant from time to time, but subject to paragraph 12(c).

       10   Withdrawal; Termination of Employment.
            -------------------------------------

       (a)  A Participant may withdraw all but not less than all the payroll
deductions credited to his/her account and not yet used to exercise his/her
purchase right under the Plan at any time by giving written notice to the
Company in a form designated by the Company. All of the Participant's payroll
deductions credited to his/her account will be paid to such Participant as soon
as practicable after receipt of such notice of withdrawal. Upon receipt of such
notice of withdrawal, the Participant's purchase right for the Purchase Period
will be automatically terminated, and no further payroll deductions for the
purchase of shares will be made during the Purchase Period. If a Participant
withdraws from a Purchase Period, payroll deductions will not resume at the
beginning of the succeeding Purchase Period unless the Participant delivers to
the Company a new subscription agreement.

       (b)  Upon a Participant's ceasing to be an eligible Employee for any
reason other than retirement, the payroll deductions credited to such
Participant's account during the Purchase Period but not yet used to exercise
his/her purchase right will be returned to such Participant or, in the case of
his/her death, to the person or persons entitled thereto under paragraph 14, and
such Participant's purchase right will be automatically terminated.

       (c)  Upon a Participant's ceasing to be an eligible Employee by reason of
his/her retirement, the provisions of this paragraph 10(c) shall apply. If such
retirement occurs three months or less prior to the next Exercise Date, the
retired Participant shall have the option of withdrawing from the Plan as
provided in paragraph 10(a), or taking no action and thereby continuing
participation in the Purchase Period in which he/she was participating at the
time of retirement. If retirement occurs more than three months prior to the
next Exercise Date, the payroll deductions credited to such retired
Participant's account during the Purchase Period but not yet used to exercise
his/her purchase right will be returned to such Participant and such
Participant's purchase right will be automatically terminated. The Plan
Administrator shall have the discretion to shorten or lengthen such period from
time to time during the term of the Plan, but such period shall in no event
exceed three months.

       11.  Interest.  No interest shall accrue on the payroll deductions of a
            --------
Participant in the Plan.

       12.  Stock.
            -----

       (a)  The maximum number of shares of the Company's Common Stock which
shall be made available for sale under the Plan shall be 2,000,000 shares,
subject to adjustment upon changes in capitalization of the Company as provided
in paragraph 18. If on a given Exercise Date the aggregate number of shares with
respect to which purchase rights are to be exercised exceeds the number of
shares then available under the Plan, the Company shall make a pro rata
allocation of the shares remaining available for purchase in as uniform a manner
as shall be practicable and as it shall determine to be equitable. If any
purchase right granted under the Plan shall terminate for any reason without
having been exercised, the Common Stock not purchased under such right shall
again become available under the Plan.

                                      -6-
<PAGE>
 
       (b)  A Participant will have no interest or voting right in shares
covered by his/her purchase right until such shares are actually purchased on
the Participant's behalf in accordance with the applicable provisions of the
Plan. No adjustment shall be made for dividends, distributions or other rights
for which the record date is prior to the date of such purchase.

       (c)  Shares to be delivered to a Participant under the Plan will be
registered in the name of the Participant, in the name of the Participant and
his/her spouse, in the name of the stockbroker at which the Participant
maintains an account in accordance with instructions provided to the Company by
the Participant pursuant to paragraph 9 or in the name of any permitted
transferee of the Participant pursuant to paragraph 15.

       (d)  The Common Stock subject to the Plan may be unissued shares,
treasury shares or shares purchased by the Company on the open market or
otherwise.

       13.  Administration.
            --------------

       (a)  The Plan shall be administered by the Plan Administrator, which
shall have full and exclusive discretionary authority to construe, interpret and
apply the terms of the Plan, to determine eligibility and to adjudicate all
disputed claims filed under the Plan. Every finding, decision and determination
made by the Plan Administrator shall, to the full extent permitted by law, be
final and binding upon all parties.

       (b)  Notwithstanding the provisions of paragraph 13(a), in the event that
Rule 16b-3 promulgated under the Exchange Act or any successor provision ("Rule
16b-3") provides specific requirements for the administrators of plans of this
type, the Plan shall be only administered by such a body and in such a manner as
shall comply with the applicable requirements of Rule 16b-3.

       14.  Designation of Beneficiary.
            --------------------------

       (a)  Participants may file a written designation of a beneficiary, on a
form designated by the Company, who is to receive any shares and cash, if any,
from the Participant's account under the Plan in the event of such Participant's
death. If a Participant is married and the designated beneficiary is not the
spouse, spousal consent shall be required for such designation to be effective.

       (b)  Such designation of beneficiary may be changed by the Participant
(and his/her spouse, if any) at any time by written notice. In the event of the
death of a Participant and in the absence of a beneficiary validly designated
under the Plan who is living at the time of such Participant's death, the
Company shall deliver such shares and/or cash to the executor or administrator
of the estate of the Participant, or if no such executor or administrator has
been appointed (to the knowledge of the Company), the Company, in its
discretion, may deliver such shares and/or cash to the spouse or to any one or
more dependents or relatives of the Participant, or if no spouse, dependent or
relative is known to the Company, then to such other person as the Company may
designate.

       15.  Transferability. Neither payroll deductions credited to a
            ---------------
Participant's account nor any rights with regard to the exercise of a purchase
right or to receive shares under the Plan may be assigned, transferred, pledged
or otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in paragraph 14 hereof) by the Participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds from a Purchase Period in accordance with paragraph 10.

       16.  Use of Funds. All payroll deductions received or held by the Company
            ------------
under the Plan may be used by the Company for any corporate purpose, and the
Company shall not be obligated to segregate such payroll deductions.

                                      -7-
<PAGE>
 
       17.  Reports. Individual accounts will be maintained for each Participant
            -------
in the Plan. Such accounts will be unfunded. Statements of account will be given
to Participants as soon as practicable following each Exercise Date, which
statements will set forth the amounts of payroll deductions, the Purchase Price,
the number of shares purchased and the remaining cash balance, if any.

       18.  Adjustments Upon Changes in Capitalization or Ownership.
            -------------------------------------------------------

       (a)  Subject to any required action by the shareholders of the Company,
the Reserves, as well as the Purchase Price with respect to each purchase right
under the Plan that has not yet been exercised, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the Plan
Administrator, whose determination in that respect shall be final, binding and
conclusive. Except as expressly provided herein, no issuance by the Company of
shares of stock of any class, or securities convertible into shares of stock of
any class, shall affect, and no adjustment by reason thereof shall be made with
respect to, the number or price of shares of Common Stock subject to purchase
rights granted under the Plan. The Plan Administrator may, if it so determines
in the exercise of its sole discretion, make provision for adjusting the
Reserves, as well as the price per share of Common Stock covered by each
outstanding purchase right, in the event the Company effects one or more
reorganizations, recapitalizations, rights offerings or other increases or
reductions of shares of its outstanding Common Stock.

       (b)  In the event that any Corporate Transaction occurs or becomes
imminent, the Board may determine, in the exercise of its sole discretion, to
shorten any Purchase Period or Purchase Periods then in progress by setting a
new Exercise Date (the "New Exercise Date"). If it elects to fix a New Exercise
Date, the Board also may, in its discretion, change the Applicable Discount, the
Compensation, the Per-Participant Limit and any aggregate share purchase limits
previously established with respect to the shortened Purchase Period or Periods.
If the Board shortens any such Purchase Period, the Board shall notify each
Participant in writing that the Exercise Date for his/her purchase right has
been changed to the New Exercise Date and that his/her purchase right will be
exercised automatically on the New Exercise Date, unless prior to such date
he/she has withdrawn from such Purchase Period as provided in paragraph 10. Such
written notice shall also include a description of any changes made to the
Applicable Discount, the Compensation, the Per-Participant Limit and any
aggregate share purchase limits made pursuant to this paragraph 18(b).

       (c)  For purposes of paragraph 18(b), the following definitions shall
apply:

       "Acquiring Person" means 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 Common Stock then outstanding, but shall not
       include the Company, any Subsidiary of the Company or any employee
       benefit plan of the Company or any Subsidiary of the Company, or any
       entity holding Common Stock for or pursuant to the terms of any such
       plan. Notwithstanding the foregoing, no Person shall become an Acquiring
       Person 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 such Person to 20%
       or more of the Common Stock of the Company then outstanding; provided,
                                                                    --------
       however, that if a Person becomes the Beneficial Owner of 20% or more of
       -------
       the Common Stock of the Company then outstanding by reason of share
       purchases by the Company and shall, after such share purchases by the
       Company, become the Beneficial Owner of any additional Common Stock of
       the Company, then such Person shall be deemed to be an Acquiring Person.

                                      -8-
<PAGE>
 
       "Affiliate" and "Associate" have the respective meanings ascribed to such

       any agreement, arrangement or understanding, or upon the exercise of
       conversion rights, exchange rights, rights (other than the Rights),
       warrants or options, or otherwise; provided, however, that a Person shall
                                          -----------------
       not be deemed the Beneficial Owner of, or to beneficially own, securities
       tendered pursuant to a tender or exchange offer made by or on behalf of
       such Person or any of such Person's Affiliates or Associates until such
       tendered securities are accepted for purchase or exchange; or (B) the
       right to vote pursuant to any agreement, arrangement or understanding;
       provided, however, that a Person shall not be deemed the Beneficial Owner
       -----------------
       of, or to beneficially own, any security if the agreement, arrangement or
       understanding to vote such security (1) arises solely from a revocable
       proxy or consent given to such person in response to a public proxy or
       consent solicitation made pursuant to, and in accordance with, the

       the extent contemplated by the proviso to clause (ii)(B) of this
       definition) or disposing of any securities of the Company; provided
       further, however, that nothing in this paragraph 18 shall cause a Person
       to be the Beneficial Owner of, or to beneficially own, any securities (x)
       acquired through such Person's participation in the business of
       underwriting securities in good faith in a firm commitment underwriting

Exchange Act, the rules and regulations promulgated thereunder, and the
requirements of any stock exchange or any automated inter-dealer quotation
system maintained by the National Association of Securities Dealers, Inc. upon
which the Common Stock may then be listed, and shall be further subject to the
approval of counsel for the Company with respect to such compliance. As a
condition to the exercise of a purchase right, the Company may require the
person exercising such purchase right to represent and warrant at the time of
any such exercise that the shares are being purchased only for investment and
without any present intention to sell or distribute such shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned applicable provisions of law.

       22.  Additional Restrictions of Rule 16b-3. The terms and conditions of
            --------------------------------------
purchase rights granted hereunder to, and the purchase of shares by, persons
subject to Section 16 of the Exchange Act shall comply with the applicable
provisions of Rule 16b-3. This Plan shall be deemed to contain, such purchase
rights shall contain, and the shares issued upon exercise thereof shall be
subject to, such additional conditions and restrictions as may be required by
Rule 16b-3 to qualify for the maximum exemption from Section 16 of the Exchange
Act with respect to Plan transactions.

            --------------
approved by the stockholders (the "Effective Date").

       24.  Term of Plan. The Plan shall continue in effect for a term of ten
            ------------
(10) years after the Effective Date unless sooner terminated under paragraph 19.
No rights may be granted under the Plan following its termination.

       25.  Shareholder Approval. Continuance of the Plan shall be subject to
approval by the shareholders of the Company within twelve (12) months before or
after the date the Plan is adopted by the Board. If such shareholder approval is

majority of the votes cast at a shareholders' meeting at which a quorum
(consisting of at least a majority of all outstanding voting stock of the
Company) is, either in person or by proxy, present and voting on the Plan, or,
if such shareholder approval is obtained by written consent, it must be obtained
by the written consent of the holders of a majority of all outstanding voting
stock of the Company; provided, however, that approval at a meeting or by
written consent may be obtained by a lesser degree of shareholder approval if
the Board determines, in its discretion after consultation with the Company's
legal counsel, that such a lesser degree of shareholder approval will comply
with all applicable laws and will not adversely affect the qualification of the
Plan under Section 423 of the Code.

       26.  No Employment Rights. The Plan does not, directly or indirectly,

create any right for the benefit of any employee or class of employees to
purchase any shares under the Plan, or create in any employee or class of
employees any right with respect to continuation of employment by the Company,
and it shall not be deemed to interfere in any way with the Company's right to
terminate, or otherwise modify, an employee's employment at any time.

receiver, trustee in bankruptcy or representative of creditors of such
Participant.

       28.  Governing Law. The law of the State of California will govern all
            -------------
matters relating to this Plan except to the extent it is superseded by the laws
of the United States.

ACUSON CORPORATION                                                 EXHIBIT 10.2
- --------------------------------------------------------------------------------

                           1995 STOCK INCENTIVE PLAN
                           -------------------------
                                        

1.  Establishment, Purpose, and Definitions.
    --------------------------------------- 

    (a) Acuson Corporation (the "Company") hereby adopts the Acuson Corporation
1995 Stock Incentive Plan (the "Plan").

    (b) The purpose of the Plan is to allow the Company to provide incentives to
Eligible Individuals (as defined in Section 4, below) for employment, increased
efforts and successful achievements on behalf of or in the interests of the
Company and its Affiliates and to maximize the rewards due them for those
efforts and achievements.  In the case of Employees (including officers and
directors who are Employees) of the Company and of its Affiliates such
incentives include (i) an opportunity to purchase shares of common stock, par
value $.0001 per share, of the Company ("Stock") pursuant to options which may
qualify as incentive stock options (referred to as "incentive stock options")
under Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"),
(ii) an opportunity to purchase shares of Stock pursuant to options which are
not described in Sections 422 or 423 of the Code (referred to as "nonqualified
stock options"), (iii) the sale or bonus of restricted Stock ("Restricted
Stock"), and (iv) the grant of stock appreciation rights ("SARs"), either
separately or in relation ("tandem") with stock options, entitling holders to
compensation measured by appreciation in the value of Stock. The Plan also
provides for the grant of similar incentives (other than incentive stock
options) to independent contractors and consultants to the Company and its
Affiliates. Finally, the Plan provides for the automatic, nondiscretionary grant
of nonqualified stock options to directors of the Company who are not Employees
of the Company or any Affiliate ("Non-Employee Directors").

    (c) Except for purposes of Section 12, the term "Affiliate" means parent or
subsidiary corporations of the Company, as defined in Sections 424(e) and (f) of
the Code (but substituting "the Company" for "employer corporation"), including
parents or subsidiaries of the Company that become such after adoption of the
Plan.

    (d) The term "Employee" means any person, including officers and directors,
who is an employee of the Company or an Affiliate for purposes of income tax
withholding under the Code. Neither service as a director nor payment of a
director's fee by the Company shall be sufficient to constitute a person an
Employee.

2.  Administration of the Plan.
    -------------------------- 

    (a) The Plan may be administered by different committees with respect to:
(i) Non-Employee Directors; (ii) Eligible Individuals who are (A) officers or
directors subject to Section 16(b) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), or (B) officers and other employees who are both
"employees" within the meaning of Section 422 of the Code and "covered
employees" within the meaning of Section 162(m)(3) of the Code ("Covered
Employees"); and (iii) Eligible Individuals who are neither officers or
directors subject to Section 16(b) of the Exchange Act nor Covered Employees.
Each committee, in addition to satisfying any specific requirements imposed by
this Section 2, shall also satisfy any legal requirements relating to the
administration of stock-based compensation plans under applicable state
corporate and securities laws and the Code ("Applicable Laws"). References
herein to the "Plan Administrator" shall refer to the applicable committee(s)
or, if the Board of Directors of the Company (the "Board") does not delegate
administration of some aspects of the Plan to a committee, shall be construed to
refer to the Board.

                                      -1-
<PAGE>
 
    (b) The Secretary of the Company shall administer the provisions of Section
5 of the Plan (providing for stock option grants to Non-Employee Directors).
This function shall be limited to matters of interpretation and administrative
oversight.

    (c) With respect to awards made to Eligible Individuals who are officers or
directors subject to Section 16(b) of the Exchange Act or Covered Employees, the
Plan shall be administered by a committee of the Board, which committee shall be
composed solely of "Non-Employee Directors" as defined in Rule 16b-3.  In
addition, awards intended to qualify as "performance based compensation" under
Section 162(m) of the Code ("Performance Based Compensation") that are made to
Covered Employees shall be made only by a committee (or subcommittee thereof)
"comprised solely of two or more outside directors" as provided under that
Section.  Once appointed, a committee shall continue to serve in its designated
capacity until otherwise directed by the Board. From time to time, the Board may
increase the size of the committee and appoint additional members, remove
members (with or without cause) and substitute new members, fill vacancies
(however caused), all to the extent permitted by Section 162(m) of the Code, the
rules and regulations with respect to each, and Applicable Laws.  The committee
shall select one of its members as chair of the committee and shall hold
meetings at such times and places as it may determine.  To the extent permitted
by Section 162(m) of the Code, the rules and regulations with respect to each,
and Applicable Laws, a majority of the committee shall constitute a quorum, and
acts of the committee at which a quorum is present, or acts reduced to or
approved in writing by all the members of the committee, shall be the valid acts
of the committee.

    (d) With respect to awards made to Eligible Individuals who are neither
officers nor directors subject to Section 16(b) of the Exchange Act nor Covered
Employees, the Plan shall be administered by (i) the Board; or (ii) a committee
of one or more persons (which may be the committee established pursuant to
Section 2(c), above) designated by the Board. Once appointed, such committee
shall continue to serve in its designated capacity until otherwise directed by
the Board. From time to time, the Board may increase the size of the committee
and appoint additional members, remove members (with or without cause) and
substitute new members, fill vacancies (however caused), and remove all members
of the committee and thereafter directly administer the Plan, all to the extent
permitted by Applicable Laws. The committee shall select one of its members as
chair of the committee and shall hold meetings at such times and places as it
may determine.  To the extent permitted by Applicable Laws, a majority of the
committee shall constitute a quorum, and acts of the committee at which a quorum
is present, or acts reduced to or approved in writing by all the members of the
committee, shall be the valid acts of the committee.

    (e) The Plan Administrator shall determine which Eligible Individuals shall
be granted options under the Plan, the timing of such grants, the terms thereof
(including any restrictions on the Stock), and the number of shares subject to
such options.

    (f) The Plan Administrator shall also determine which Eligible Individuals
shall be granted or issued SARs or Restricted Stock (other than pursuant to the
exercise of options) under the Plan, the timing of such grants or issuances, the
terms thereof (including any restrictions and the consideration, if any, to be
paid therefor) and the number of shares or SARs to be granted.

    (g) Except for options granted to Non-Employee Directors pursuant to Section
5, the Plan Administrator may amend the terms of any outstanding option or SAR
granted under this Plan, but any amendment that would adversely affect the
holder's rights under an outstanding option or SAR shall not be made without the
holder's written consent.  The Plan Administrator may, with the holder's written
consent, cancel any outstanding option or SAR or accept any outstanding option
or SAR in exchange for a new option or SAR.  The Plan Administrator also may
amend any Restricted Stock purchase agreement or Restricted Stock bonus
agreement relating to sales or bonuses of Restricted Stock under the Plan, but
any amendment that would adversely affect the individual's rights to the
Restricted Stock shall not be made without his or her written consent.

                                      -2-
<PAGE>
 
    (h) The Plan Administrator shall have the sole authority, in its absolute
discretion, to adopt, amend, and rescind such rules and regulations as, in its
opinion, may be advisable for the administration of the Plan, to construe and
interpret the Plan, the rules and the regulations, and the instruments
evidencing options, SARs or Restricted Stock granted or issued under the Plan
and to make all other determinations deemed necessary or advisable for the
administration of the Plan.  All decisions, determinations, and interpretations
of the Plan Administrator shall be binding on all participants.  Notwithstanding
the foregoing, the Plan Administrator shall not exercise any discretionary
functions with respect to options granted to Non-Employee Directors pursuant to
Section 5.

3.  Stock Subject to the Plan.
    ------------------------- 

    (a) The maximum aggregate number of shares of Stock available for issuance
under the Plan and during the life of the Plan shall equal 3,500,000 shares,
subject to adjustment from time to time in accordance with this Section 3.  The
Stock subject to the Plan may be unissued shares, treasury shares or shares
purchased by the Company on the open market or otherwise.

    (b)  For purposes of the limitation specified in Section 3(a), the following
principles shall apply:

         (1) the following transactions, if granted pursuant to this Plan, shall
         count against and decrease the number of shares of Stock that may be
         issued for purposes of Section 3(a): (i) shares of Stock subject to
         outstanding options, outstanding shares of Restricted Stock, and shares
         subject to SARs granted independently of options (based upon a good
         faith estimate by the Company or the Plan Administrator of the maximum
         number of shares for which the SAR may be settled (assuming payment in
         full in shares of Stock), and (ii) in the case of options granted in
         tandem with SARs, the greater of the number of shares of Stock that
         would be counted if one or the other alone was outstanding (determined
         as described in clause (i) above);

         (2) the following shall be added back to the number of shares of Stock
         that may be issued for purposes of Section 3(a): (i) shares of Stock
         with respect to which options, SARs granted independent of options, or
         Restricted Stock awards expire, are cancelled, or otherwise terminate
         without being exercised, converted, or vested, as applicable, and (ii)
         in the case of options granted in tandem with SARs, shares of Stock as
         to which an option has been surrendered in connection with the exercise
         of a tandem SAR, to the extent the number surrendered exceeds the
         number issued upon exercise of the SAR; provided that, in any case, the
                                                 -------------                  
         holder of such awards did not receive any dividends or other benefits
         of ownership with respect to the underlying shares being added back,
         other than voting rights and the accumulation (but not payment) of
         dividends of Stock;

         (3) shares of Stock subject to SARs granted independently of options
         (calculated as provided in clause (1) above) that are exercised and
         paid in cash shall be added back to the number of shares of Stock that
         may be issued for purposes of Section 3(a), provided that the holder of
         such SAR did not receive any dividends or other benefits of ownership,
         other than voting rights and the accumulation (but not payment) of
         dividends, relative to the shares of Stock subject to the SARs;

         (4) shares of Stock that are transferred by a holder of an award (or
         withheld by the Company) as full or partial payment to the Company of
         the purchase price of shares of Stock subject to an option or the
         Company's or any Affiliate's tax withholding obligations shall not be
         added back to the number of shares of Stock that may be issued for
         purposes of Section 3(a) and shall not again be subject to awards; and

                                      -3-
<PAGE>
 
         (5) if the number of shares of Stock counted against the number of
         shares that may be issued for purposes of Section 3(a) is based upon an
         estimate made by the Company or the Plan Administrator as provided in
         clause (1) above and the actual number of shares of Stock issued
         pursuant to the applicable award is greater or less than the estimated
         number, then upon such issuance, the number of shares of Stock that may
         be issued pursuant to Section 3(a) shall be further reduced by the
         excess issuance or increased by the shortfall, as applicable.

     (c) If there is any change in the Stock through merger, consolidation,
reorganization, recapitalization, reincorporation, stock split, stock dividend
(in excess of 2%), or other change in the capital structure of the Company,
appropriate adjustments shall be made by the Plan Administrator, in order to
preserve but not to increase the benefits to the outstanding options, SARs and
Restricted Stock purchase or Restricted Stock bonus awards under the Plan,
including adjustments to the aggregate number and kind of shares subject to the
Plan, or to outstanding Restricted Stock purchase or Restricted Stock bonus
agreements, or SAR agreements, and the number and kind of shares and the price
per share subject to outstanding options.

     (d) The Plan Administrator shall have the discretion, to the extent
permitted by Applicable Law, to include provisions in any agreements evidencing
awards granted under the Plan providing that, in the event of a dissolution,
liquidation, merger or consolidation of the Company, or any other event that the
Plan Administrator deems to have effected a change in control of the Company,
any such awards shall accelerate and become fully vested, and all forfeiture
and/or transfer restrictions with respect thereto shall lapse, regardless of
whether such awards are otherwise to be assumed or replaced in connection with
such event.

4.   Eligible Individuals.  Individuals who shall be eligible to have the Plan
     --------------------                                                     
Administrator grant to them options, SARs or Restricted Stock under the Plan
("Eligible Individuals") shall be such employees, officers (including officers
who are directors of the Company), independent contractors, and consultants of
the Company or an Affiliate as the Plan Administrator, in its discretion, shall
designate from time to time.  Notwithstanding the foregoing, only Employees
shall be eligible to receive incentive stock options.  Eligible Individuals
shall not include Non-Employee Directors.  Non-Employee Directors shall receive
automatic and nondiscretionary option grants pursuant to Section 5 and will not
be otherwise eligible to receive any other option grants or awards of SARs or
Restricted Stock under the Plan or any other stock plan of the Company or any
Affiliate.

5.   Automatic Option Grants to Non-Employee Directors.
     ------------------------------------------------- 

     (a)  All grants of options pursuant to this Section 5 shall be automatic
and nondiscretionary and shall be made strictly in accordance with the
provisions of this Section 5. No person shall have any discretion to determine
which Non-Employee Directors shall be granted options, the number of shares of
Stock to be covered by options granted to Non-Employee Directors, the timing of
such option grants or the exercise price thereof.

     (b)  An option to purchase 7,500 shares of Stock shall be granted to each
Non-Employee Director continuing in office immediately following each annual
meeting of the Company's stockholders which occurs on or after the date of
approval of the Plan by the stockholders of the Company and prior to the
termination of the Plan.

     (c)  The term of each option granted pursuant to this Section 5 shall be
ten years from the date of grant, unless a shorter period is required to comply
with any Applicable Law, and except for the early termination provisions
contained in the written stock option agreement in the form of Exhibit A hereto,
in either of which cases such shorter period shall apply.

                                      -4-
<PAGE>
 
     (d)  Each option granted pursuant to this Section 5 shall vest and become
fully exercisable as to fifty percent (50%) of the shares subject to the option
on the date which is six (6) months from the date the option is granted, then
daily thereafter as to 1/365th of the total shares subject to the option so that
the option is fully exercisable no later than one year following the date the
option is granted.

     (e)  Each option grant to an Non-Employee Director pursuant to this Section
5 shall be evidenced by a written stock option agreement, in the form of Exhibit
A hereto, executed by the Company and the Non-Employee Director to whom such
option is automatically granted.

6.   Terms and Conditions of Options.
     ------------------------------- 

     (a)  Each option granted pursuant to the Plan will be evidenced by a
written stock option agreement executed by the Company and the person to whom
such option is granted.

     (b)  Except for options granted under Section 5 above, the Plan
Administrator shall determine the term of each option granted under the Plan;
provided, however, that the term of an incentive stock option shall not be for
more than ten years and that, in the case of an incentive stock option granted
to a person possessing more than 10% of the combined voting power of the Company
or an Affiliate on the date the option is granted, the term of each incentive
stock option shall be no more than five years.

     (c)  In the case of incentive stock options, the aggregate fair market
value (determined as of the time such option is granted) of the Stock with
respect to which incentive stock options are exercisable for the first time by
an Eligible Individual in any calendar year (under this Plan and any other plans
of the Company or its Affiliates) shall not exceed $100,000. If the aggregate
fair market value of the Stock with respect to which incentive stock options are
exercisable by an optionee for the first time in any calendar year exceeds
$100,000, such options shall be treated, to the minimum extent required to
preserve incentive stock option treatment for as many options as possible, as
nonqualified stock options. The rule set forth in the preceding sentence shall
be applied by taking options into account in the order in which they were
granted.

     (d)  The exercise price of each incentive stock option shall be not less
than the per share fair market value of the Stock subject to such option on the
date the option is granted. The exercise price of each nonqualified stock option
shall be as determined by the Plan Administrator. Notwithstanding the foregoing,
(i) in the case of an incentive stock option granted to a person possessing more
than 10% of the combined voting power of the Company or an Affiliate on the date
the option is granted, the exercise price shall be not less than 110% of the
fair market value of the Stock on the date the option is granted, and (ii) in
the case of an option granted pursuant to Section 5 above and an option intended
to qualify as Performance Based Compensation, the exercise price shall be not
less than the per share fair market value of the Stock subject to such option on
the date the option is granted. The exercise price of an option shall be subject
to adjustment to the extent provided in Section 3(c), above.

     (e)  Except for options granted under Section 5 above, the stock option
agreement may contain such other terms, provisions, and conditions consistent
with this Plan as may be determined by the Plan Administrator. If an option, or
any part thereof, is intended to qualify as an incentive stock option, the stock
option agreement shall contain those terms and conditions which are necessary to
so qualify it.

     (f)  The maximum number of shares of Stock with respect to which SARs or
options to acquire Stock may be granted to any individual during any calendar
year shall not exceed 1,000,000 shares (which number may be increased without
stockholder approval to reflect adjustments under Section 3(c), above, to the
extent such increase does not cause the grant to fail to qualify as remuneration
payable solely on account of one or more performance goals within the meaning of
Section 162(m) of the Code). To the extent required by Section 162(m) of the
Code or the regulations thereunder, in applying the foregoing limitation with
respect to any employee, if any option is cancelled, the cancelled option 

                                      -5-
<PAGE>
 
shall continue to count against the maximum number of shares for which options
may be granted to the employee under this Section 6(f). For this purpose, the
repricing of an option shall be treated as a cancellation of the existing option
and the grant of a new option to the extent required by Section 162(m) of the
Code or the regulations thereunder.

7.   Payment Upon Exercise of Options.
     -------------------------------- 

     (a)  Payment of the purchase price upon exercise of any option granted
under this Plan shall be made in cash, by optionee's personal check, a certified
check, bank draft, or postal or express money order payable to the order of the
Company in lawful money of the United States (collectively, "Cash
Consideration"); provided, however, that, except for options granted under
Section 5 above, the Plan Administrator, in its sole discretion, may permit an
optionee to pay the option price in whole or in part (i) with shares of Stock
owned by the optionee or with shares of Stock withheld from the shares otherwise
deliverable to the optionee upon exercise of an option; (ii) by delivery on a
form prescribed by the Company of an irrevocable direction to a securities
broker approved by the Company to sell shares of Stock and deliver all or a
portion of the proceeds to the Company in payment for the Stock; (iii) by
delivery of the optionee's promissory note with such recourse, interest,
security, and redemption provisions as the Plan Administrator in its discretion
determines appropriate; or (iv) in any combination of the foregoing. The
exercise price of any options granted under Section 5 above, shall be paid in
Cash Consideration, the consideration specified in clauses (i) or (ii) of the
preceding sentence or in any combination thereof. Any Stock used to exercise
options shall be valued at its fair market value on the date of the exercise of
the option. In addition, the Plan Administrator, in its sole discretion, may
authorize the surrender by an optionee of all or part of an unexercised option
(excluding options granted under Section 5 above) and authorize a payment in
consideration thereof of an amount equal to the difference between the aggregate
fair market value of the Stock subject to such option and the aggregate option
price of such Stock. In the Plan Administrator's discretion, such payment may be
made in cash, shares of Stock with a fair market value on the date of surrender
equal to the payment amount, or some combination thereof.

     (b)  In the event that the exercise price is satisfied by shares withheld
from the shares of Stock otherwise deliverable to the optionee, the Plan
Administrator may issue the optionee an additional option, with terms identical
to the option agreement under which the option was exercised, entitling the
optionee to purchase additional shares of Stock equal to the number of shares so
withheld but at an exercise price equal to the fair market value of the Stock on
the grant date of the new option; provided, however, that no such additional
options may be granted with respect to options granted pursuant to Section 5,
above.

8    Terms and Conditions of Restricted Stock Purchases and Bonuses
     --------------------------------------------------------------

     (a)  Each sale (other than upon exercise of options) or bonus grant of
Restricted Stock pursuant to the Plan will be evidenced by a written Restricted
Stock purchase or Restricted Stock bonus agreement, as applicable, executed by
the Company and the person to whom such Restricted Stock is sold or granted.

     (b)  The Restricted Stock purchase agreement or Restricted Stock bonus
agreement may contain such terms, provisions, and conditions consistent with
this Plan as may be determined by the Plan Administrator, including not by way
of limitation, payment terms, restrictions on transfer, forfeiture provisions,
repurchase provisions, and vesting provisions.

     (c)  The Plan Administrator may condition the award or the exercise of any
right under an award under this Section 8 upon the attainment of one or more
preestablished objective performance goals meeting the requirements of Section
162(m) of the Code and the regulations thereunder.

9.   Terms and Conditions of SARs.  The Plan Administrator may, under such terms
     ----------------------------                                               
and conditions as it deems appropriate, authorize the issuance of SARs evidenced
by a written SAR agreement (which, in 

                                      -6-
<PAGE>
 
the case of tandem options, may be part of the option agreement to which the SAR
relates) executed by the Company and the person to whom the SARs are granted.
The SAR agreement shall specify the term for the SARs covered thereby and
contain such other terms, provisions and conditions consistent with this Plan as
may be determined by the Plan Administrator.

10.  Withholding Taxes.
     ----------------- 

     (a)  No Stock shall be granted or sold under the Plan to any Eligible
Individual, and no SAR may be exercised, until the individual has made
arrangements acceptable to the Plan Administrator for the satisfaction of
federal, state, and local income and employment tax withholding obligations,
including without limitation obligations incident to the receipt of Stock under
the Plan, the lapsing of restrictions applicable to such Stock, the failure to
satisfy the conditions for treatment as incentive stock options under applicable
tax law, or the receipt of cash payments. Upon the exercise of an option or the
lapsing of a restriction on Stock issued under the Plan, the Company (or the
optionee's or stockholder's employer) may withhold from the shares otherwise
deliverable to the optionee upon such exercise, or require the stockholder to
surrender shares of Stock as to which the restriction has lapsed, such number of
shares having a fair market value sufficient to satisfy federal, state and local
income and employment tax withholding obligations.

     (b)  In the event that such tax withholding is satisfied by the Company or
the optionee's employer withholding shares of Stock otherwise deliverable to the
optionee, the Plan Administrator may issue the optionee an additional option,
with terms identical to the option agreement under which the option was
exercised, entitling the optionee to purchase additional shares of Stock equal
to the number of shares so withheld but at an exercise price equal to the fair
market value of the Stock on the grant date of the new option; provided,
however, that no such additional options may be granted with respect to options
granted pursuant to Section 5, above.

11.  Assignability.  Incentive Stock Options shall be transferable by the holder
     -------------                                                              
only by operation of law or by will or the laws of descent and distribution.
Any other option or SAR shall be transferable to the extent provided in the
option agreement or SAR agreement covering the option or SAR, and the Plan
Administrator shall have the discretion to amend any such outstanding option or
SAR to provide for broader transferability of the option or SAR as the Plan
Administrator may authorize within the limitations of Rule 16b-3.  Stock subject
to a Restricted Stock purchase agreement or a Restricted Stock bonus agreement
shall be transferable only as provided in such agreement.  Notwithstanding the
foregoing, if required by the Code, each incentive stock option under the Plan
shall be transferable by the optionee only by will or the laws of descent and
distribution, and, during the optionee's lifetime, be exercisable only by the
optionee.  In the event of any Rule 16b-3 permitted transfer of an option
hereunder, the transferee shall be entitled to exercise the option in the same
manner and only to the same extent as the optionee (or his/her personal
representative or the person who would have acquired the right to exercise the
option by bequest or intestate succession) would have been entitled to exercise
the option under Sections 5, 6 and 7 had the option not been transferred.

12.  Change in Control.
     ----------------- 

     (a)  Notwithstanding anything to the contrary contained in the Plan, each
stock option, SAR, Restricted Stock bonus or Restricted Stock purchase agreement
(or an amendment thereto) evidencing an option, SAR, Restricted Stock bonus or
Restricted Stock purchase hereunder shall automatically and without further
action be fully vested, nonforfeitable and become exercisable, and any
Restricted Stock covered by such an agreement shall be released from
restrictions on transfer and repurchase or forfeiture rights, on the twenty-
second day after any Share Acquisition Date, unless prior to such twenty-second
day a majority of the Continuing Directors then in office has determined that
the transaction pursuant to which a Person has become an Acquiring Person is an
Approved Transaction.

     (b)  Certain Definitions.  For purposes of this Section 12, the following
          -------------------

the Common Shares then outstanding, but shall not include the Company, any
Subsidiary of the Company or any employee benefit plan of the Company or any
Subsidiary of the Company, or any entity holding Common Shares for or pursuant

the Company which, by reducing the number of shares outstanding, increases the
proportionate number of shares beneficially owned by such Person to 20% or more
of the Common Shares of the Company then outstanding; provided, however, that if
                                                      -----------------
a Person becomes the Beneficial Owner of 20% or more of the Common Shares of the

Affiliates or Associates beneficially owns, directly or indirectly; (ii) which

and (2) is not also then reportable on Schedule 13D under the Exchange Act (or
any comparable or successor report); or (iii) which are beneficially owned,
directly or indirectly, by any other Person with which such Person or any of
such Person's Affiliates or Associates has any agreement, arrangement or
understanding for the purpose of acquiring, holding, voting (except to the
extent contemplated by the proviso to clause (ii)(B) of this definition) or
disposing of any securities of the Company; provided further, however, that
nothing in this Section 12 shall cause a Person to be the Beneficial Owner of,
or to beneficially own, any securities (x) acquired through such Person's
participation in the business of underwriting securities in good faith in a firm
commitment underwriting until the expiration of forty days after the date of

     (a)  The Board may at any time amend, suspend or terminate the Plan as it
deems advisable; provided that such amendment, suspension or termination
complies with all applicable requirements of state and federal law, including
any applicable requirement that the Plan or an amendment to the Plan be approved
by the stockholders, and provided further that, except as provided in Section
3(c) above, the Board shall in no event amend the Plan in the following respects

                              ACUSON CORPORATION

         NON-EMPLOYEE DIRECTORS' NON-QUALIFIED STOCK OPTION AGREEMENT
         ------------------------------------------------------------

        This agreement (the "Agreement") is made as of __________ __, 199__ (the
"Grant Date") between Acuson Corporation (the "Company") and _________________
("Optionee").


                                  WITNESSETH:

        WHEREAS, the Company has adopted the Acuson Corporation 1995 Stock
Incentive Plan (the "Plan"), which Plan is incorporated in this Agreement by
reference and made a part of it (capitalized terms shall have the meaning
ascribed to them in the Plan); and

        WHEREAS, the Plan provides for automatic option grants to Non-Employee
Directors of the Company;

        NOW, THEREFORE, in consideration of the mutual covenants hereinafter set
forth, the parties to this Agreement hereby agree as follows:


        1.   Option Grant. The Company hereby grants to Optionee the right and
             ------------
option to purchase from the Company on the terms and conditions hereinafter set
forth, all or any part of an aggregate of seven thousand five hundred (7,500)
shares of the Common Stock, $.0001 par value, of the Company (the "Stock"). The
exercise price of the Stock subject to this option shall be $_______ per share,
which is not less than the fair market value per share of the Stock on the Grant
Date. This grant is an automatic option grant under Section 5 of the Plan.

        2.   Option Period. This option shall be exercisable only during the
             -------------
period (the "Option Period") commencing on the Grant Date and, except as
provided in paragraph 3, ending on the date (the "Terminal Date") which shall be
ten years from the Grant Date. During the Option Period, the exercisability of
this option shall be subject to the limitations of paragraph 3 and the vesting
provisions of paragraph 4.

        3.   Limits on Option Period. The Option Period may end before the
             -----------------------
Terminal Date, as follows:

             (a)  If Optionee ceases to be a director on the Company's Board of
Directors (the "Board") for any reason other than death, disability (within the
meaning of subparagraph (c) below) or cause during the Option Period, the Option
Period shall terminate on the earlier of (i) the last day of the period,
beginning on the day next following the day on which the Optionee ceases to be a
director, which equals in length the most recent period of the Optionee's
continuous service as a director (including all portions of such period prior to
the Grant Date), (ii) three years after the date Optionee ceases to be a
director, or (iii) the Terminal Date. In each case this option shall be
exercisable only to the extent exercisable under paragraph 4 on the date
Optionee ceases to be a director.

             (b)  If Optionee should die while serving on the Board, the Option
Period shall terminate three years after the date of death or on the Terminal
Date, whichever shall first occur, and this option shall be exercisable only to
the extent exercisable under paragraph 4 on the date of Optionee's 

                                      -11-
<PAGE>
 
death. In the event of Optionee's death, Optionee's executor or administrator or
the person or persons to whom Optionee's rights under this option shall pass by
will or by the applicable laws of descent and distribution may exercise the
entire unexercised portion of this option to the extent exercisable on the date
of Optionee's death.

             (c)  If Optionee ceases to be a director by reason of disability,
as defined below, the Option Period shall terminate three years after the date
Optionee ceases to be a director or on the Terminal Date, whichever shall first
occur, and this option shall be exercisable only to the extent exercisable under
paragraph 4 on the date Optionee ceases to be a director. For purposes of this
subparagraph (c), an individual is disabled if he or she is unable to engage in
any substantial gainful activity by reason of any medically determinable
physical or mental impairment which can be expected to result in death or which
has lasted or can be expected to last for a continuous period of not less than
12 months. An individual shall not be considered to be disabled unless he or she
furnishes proof of the existence thereof in such form and manner, and at such
times, as the Board may require.

             (d)  If Optionee is removed from the Board for cause during the
Option Period, the Option Period shall terminate on the date of such Optionee's
removal as a director and shall not thereafter be exercisable to any extent.

        4.   Vesting of Right to Exercise Options.
             ------------------------------------

             (a)  This option shall vest as to fifty percent (50%) of the number
of shares originally covered by this option on the date which is six months from
the Grant Date, then daily thereafter in installments of 1/365th of the total
shares subject to this option so that this option will become fully vested and
exercisable no later than one (1) year following the Grant Date.

             (b)  Vesting of this option will cease prior to this option
becoming fully vested at such time that Optionee ceases to be a director of the
Company, including by reason of death or disability.

             (c)  Fractional shares shall not vest until such time as additional
fractional shares included in other installments allocated to this option can be
combined with the existing fractional shares to constitute one or more whole
shares.

             (d)  Notwithstanding the foregoing, this option shall be fully
vested and nonforfeitable and shall become fully exercisable under the
circumstances specified in Section 12 of the Plan.

        5.   Method of Exercise.
             ------------------

             (a)  Optionee may exercise this option with respect to all or any
part of the shares of Stock then subject to such exercise by giving the Company
written notice of such exercise, specifying the number of such shares as to
which this option is exercised. Such notice shall be accompanied by an amount
equal to the exercise price of such shares, in any of the forms permitted under
Section 7 of the Plan.

             (b)  If required by the Company, Optionee shall give the Company
satisfactory assurance in writing, signed by Optionee or Optionee's legal
representative, as the case may be, that such shares are being purchased for
investment and not with a view to the distribution thereof, provided that such
assurance shall be deemed inapplicable to (i) any sale of such shares by such
Optionee made in accordance with the terms of a registration statement covering
such sale, which has heretofore been (or may hereafter be) filed and become
effective under the Securities Act of 1933, as amended, and with respect to
which no stop order suspending the effectiveness thereof has been issued, and
(ii) any other sale of such shares with respect to which, in the opinion of
counsel for the Company, such assurance is 

                                      -12-
<PAGE>
 
not required to be given in order to comply with the provisions of the
Securities Act of 1933, as amended.

             (c)  As soon as practicable after receipt of the notice required in
paragraph 5(a) and satisfaction of the conditions set forth in paragraph 5(b),
the Company shall, without transfer or issue tax and without other incidental
expense to Optionee, deliver to Optionee at the office of the Company at 1220
Charleston Road, Mountain View, CA 94043, attention of the Corporate Secretary,
or such other place as may be mutually acceptable to the Company and Optionee, a
certificate or certificates for such shares of Stock; provided, however, that
the time of such delivery may be postponed by the Company for such period as may
be required for it with reasonable diligence to comply with applicable
registration requirements under the Securities Act of 1933, as amended, the
Securities Exchange Act of 1934, as amended, any applicable listing requirements
of any national securities exchange, and requirements under any other law or
regulation applicable to the issuance or transfer of such shares. If Optionee
fails to accept delivery of and pay for all or any part of the number of shares
specified in such notice upon tender or delivery thereof, Optionee's right to
purchase such shares may be terminated by the Company at its election. In no
event shall the Company be required to issue fractional shares upon the exercise
of this option.

        6.   Withholding. Optionee agrees to make appropriate arrangements with
             -----------
the Company for satisfaction of any applicable federal, state or local income
tax withholding requirements or social security requirements.

        7.   Changes in Capitalization. If there should be any change in a class
             -------------------------
of Stock subject to this option, through merger, consolidation, reorganization,
recapitalization, reincorporation, stock split, stock dividend (in excess of two
percent) or other change in the capital structure of the Company, appropriate
adjustments shall be made in order to preserve, but not to increase, the
benefits to Optionee, including adjustments of the number and kind of shares of
such Stock subject to this option and of the price per share. Any adjustment
made pursuant to this paragraph 7 as a consequence of a change in the capital
structure of the Company shall not entitle Optionee to acquire a number of
shares of such Stock of the Company or shares of stock of any successor company
greater than the number of shares Optionee would receive if, prior to such
change, Optionee had actually held a number of shares of such Stock equal to the
number of shares subject to this option.

        8.   Limitations on Transfer. To the extent required by Rule 16b-3 under
             -----------------------
the Securities Exchange Act of 1934, as amended, this option shall not be
transferable by Optionee other than by operation of law or by will or by the
laws of descent or distribution; provided that, if Rule 16b-3 is amended after
the Board's adoption of the Plan to permit greater transferability, this option
shall be transferable to the fullest extent provided by Rule 16b-3 as so
amended. In the event of any Rule 16b-3 permitted transfer of this option, the
transferee shall be entitled to exercise this option in the same manner and only
to the same extent as the Optionee (or his or her personal representative or the
person who would have acquired the right to exercise this option by bequest or
intestate succession) would have been entitled to exercise this option had this
option not been transferred.

        9.   No Stockholder Rights. Neither Optionee nor any person to whom this
             ---------------------
option is transferred pursuant to paragraph 8 nor any person entitled to
exercise Optionee's rights in the event of Optionee's death shall have any of
the rights of a stockholder with respect to the shares of Stock subject to this
option except to the extent the certificates for such shares shall have been
issued upon the exercise of this option.

        10.  No Employment Right. Nothing in the Plan or this Agreement shall
             -------------------
confer upon the Optionee any right to continue service as a director of the
Company or any Affiliate or shall affect the right of the Company or any
Affiliate or the shareholders of the Company or any Affiliate, as the case may
be, to terminate the directorship of Optionee, with or without cause.

                                      -13-

        11.  Notice. Any notice required to be given to the Company under the
             ------
terms of this Agreement shall be given in writing and addressed to the Company
in care of its Corporate Secretary at the office of the Company at 1220
Charleston Road, Mountain View, CA 94043, and any notice to be given to Optionee
shall be given in writing and addressed to Optionee at the address given by
Optionee beneath Optionee's signature to this Agreement, or such other address

other. Any such notice shall be deemed to have been duly given when enclosed in
a properly sealed envelope addressed as aforesaid, registered or certified and
deposited (postage and registration or certification fee prepaid) in a post
office or branch post office regularly maintained by the United States.

        12.  Successors. This Agreement shall be binding upon and inure to the
             ----------
benefit of any successor or successors of the Company. Where the context
permits, "Optionee" as used in this Agreement shall include Optionee's executor,
administrator or other legal representative or the person or persons to whom
Optionee's rights pass by will or the applicable laws of descent and
distribution.

        13.  Applicable Law. The interpretation, performance, and enforcement of
             --------------
this Agreement shall be governed by the laws of the State of California.

        IN WITNESS WHEREOF, this Agreement has been executed as of the day and
year first written above.

ACUSON CORPORATION                                                  EXHIBIT 10.3
- --------------------------------------------------------------------------------

                           1991 STOCK INCENTIVE PLAN

1.    PURPOSE.
      ------- 

      (a) The purpose of the Plan is to provide a means by which selected
employees and directors (as provided under paragraph 5 or paragraph 6) of and
consultants to Acuson Corporation, a Delaware Corporation (the "Company"), and
its Affiliates, as defined in subparagraph 1(b), may be given an opportunity to
purchase stock of the Company.  It is intended that this purpose will be
effected through the granting of (a) incentive stock options and (b)
nonstatutory stock options.

      (b) The word "Affiliate" as used in the Plan means any parent corporation
or subsidiary corporation of the Company, as those terms are defined in Sections
424(e) and (f), respectively, of the Internal Revenue Code of 1986, as amended
(the "Code").

      (c) The Company, by means of the Plan, seeks to retain the services of
persons now employed by or serving as consultants or directors to the Company,
to secure and retain the services of persons capable of filling such positions,
and to provide incentives for such persons to exert maximum efforts for the
success of the Company.

      (d) The Company intends that the stock options granted under the Plan
("Stock Awards") shall, in the discretion of the Board of Directors of the
Company (the "Board") or any committee to which responsibility for
administration of the Plan has been delegated pursuant to subparagraph 2(c), be
either:  incentive stock options as that term is used in Section 422 of the Code
("Incentive Stock Options"), or options which do not qualify as incentive stock
options ("Supplemental Stock Options").  All options shall be separately
designated Incentive Stock Options or Supplemental Stock Options at the time of
grant, and in such form as issued pursuant to paragraph 7, and a separate
certificate or certificates shall be issued for shares purchased on exercise of
each type of option.  An option designated as a Supplemental Stock Option will
not be treated as an Incentive Stock Option.

2.    ADMINISTRATION.
      -------------- 

      (a) The Plan shall be administered by the Board unless and until the Board
delegates administration to a committee, as provided in subparagraphs 2(c) and
2(e).

      (b) The Board shall have the power, subject to, and within the limitations
of, the express provisions of the Plan:

         (1) To determine from time to time which of the persons eligible under
the Plan shall be granted Stock Awards; when and how the Stock Awards shall be
granted; whether a Stock Award will be an Incentive Stock Option, a Supplemental
Stock Option, or a combination of the foregoing, the provisions of each Stock
Award granted (which need not be identical), including the time or times when a
person shall be permitted to purchase or receive stock pursuant to a Stock
Award; and the number of shares with respect to which Stock Awards shall be
granted to each such person.

         (2) To construe and interpret the Plan and Stock Awards granted under
it, and to establish, amend and revoke rules and regulations for its
administration.  The Board, in the exercise of this power, may correct any
defect, omission or inconsistency in the Plan or in any Stock Award, in a manner
and to the extent it shall deem necessary or expedient to make the Plan fully
effective.

         (3) To amend the Plan as provided in paragraph 13.

         (4) Generally, to exercise such powers and to perform such acts as the
Board deems necessary or expedient to promote the best interests of the Company.

      (c) The Board may delegate administration of the Plan to one or more
committees (each a "Committee").  In the case of Stock Awards by a Committee to
officers of the Company or members of the Board, the Committee  shall be
composed of not fewer than two (2) members, all of the members of which
Committee shall be persons who in the 

                                      -1-
<PAGE>
 
opinion of counsel to the Company are Non-Employee Directors within the meaning
of Rule 16b-3 under the Securities Exchange Act of 1934, as amended (the
"Exchange Act"). The board may delegate to a committee of one (1) or more
members of the Board the authority to grant options to eligible persons who are
not officers of the Company or members of the Board. If administration is
delegated to a Committee, the Committee shall have, in connection with the
administration of the Plan, the powers theretofore possessed by the Board,
subject, however, to such resolutions, not inconsistent with the provisions of
the Plan, as may be adopted from time to time by the Board. Subject to
subparagraph 2(d) the Board may abolish the Committee at any time and revest in
the Board the administration of the Plan.

      (d) The Board may delegate to a committee of one (1) or more members of
the Board the authority to grant options to eligible persons who are not
officers of the Company or members of the Board.

3.    STRUCTURE OF THE PLAN.
      --------------------- 

      (a) The Plan shall be divided into two (2) separate components:  an option
grant program whereby certain employees, directors and consultants to the
Company described in paragraph 5 shall be eligible for option grants in the
discretion of the Board (the "Regular Option Grant Program") and the automatic
option grant program described in paragraph 6 (the "Automatic Option Grant
Program").  Under the Automatic Option Grant Program, directors who are not
otherwise employees of the Company or any Affiliate of the Company ("Non-
Employee Directors") shall automatically be granted options to purchase shares
of common stock of the Company.

4.    SHARES SUBJECT TO THE PLAN.
      -------------------------- 

      (a) Subject to the provisions of paragraph 12 relating to adjustments upon
changes in stock, the stock that may be sold pursuant to Stock Awards granted
under the Plan shall not exceed in the aggregate five million (5,000,000) shares
of the Company's common stock.  If any Stock Award granted under the Plan shall
for any reason expire or otherwise terminate without having been exercised in
full, the stock not purchased under such option shall again become available for
the Plan.

      (b) The stock subject to the Plan may be unissued shares or reacquired
shares bought on the market or otherwise.

      (c) An Incentive Stock Option may be granted to an eligible person under
the Plan only if the aggregate fair market value (determined at the time the
option is granted) of the stock with respect to which Incentive Stock Options (
as defined in the Code) granted after 1986 are exercisable for the first time by
such optionee during any calendar year under all incentive stock option plans of
the Company and its Affiliates does not exceed one hundred thousand dollars
($100,000).

5.    ELIGIBILITY.
      ----------- 

      (a) Incentive Stock Options may be granted only to employees (including
officers) of the Company or its Affiliates.  A director of the Company who is
not an employee of the Company shall only be eligible to receive Stock Awards
pursuant to Section 6 of the Plan.  Stock Awards other than Incentive Stock
Options may be granted only to directors, officers or employees of or
consultants to the Company or its Affiliates.

      (b) No person shall be eligible for the grant of an Incentive Stock Option
under the Plan if, at the time of grant, such person owns (or is deemed to own
pursuant to Section 424(d) of the Code) stock possessing more than ten percent
(10%) of the total combined voting power of all classes of stock of the Company
or of any of its Affiliates unless the exercise price of such Incentive Stock
Option is at least one hundred ten percent (110%) of the fair market value of
such stock at the date of grant and the term of the option does not exceed five
(5) years from the date of grant.

                                      -2-
<PAGE>
 
6.    NON-DISCRETIONARY GRANTS.
      ------------------------ 

      Each Non-Employee Director shall automatically be granted an option to
purchase five thousand (5,000) shares of the Company's common stock upon the
date of the first annual meeting of the Company following the adoption of the
Plan by the Board and at each subsequent annual meeting of the Company at which
such Non-Employee Director is elected or re-elected as a director of the
Company, and each Non-Employee Director who is also a member of the Executive
Committee of the Board of Directors shall automatically be granted an option to
purchase an additional five thousand (5,000) shares of the Company's common
stock upon the date of each such annual meeting; provided, however, that no
option shall become exercisable under the Plan until stockholder approval of the
Plan has been obtained.  The Company intends that the options issued to such
Non-Employee Directors not be Incentive Stock Options as that term is used in
Section 422 of the Code.

7.    OPTION PROVISIONS.
      ----------------- 

      Each option shall be in such form and shall contain such terms and
conditions as the Board or the Committee shall deem appropriate.  The provisions
of separate options need not be identical, but each option shall include
(through incorporation of provisions hereof by reference in the option or
otherwise) the substance of each of the following provisions:

      (a) The term of any option shall not be exercisable after the expiration
of ten (10) years from the date it was granted.

      (b) The exercise price of each Incentive Stock Option and each option
granted pursuant to the Automatic Option Grant Program shall be not less than
one hundred percent (100%) of the fair market value of the stock subject to the
option on the date the option is granted.  The exercise price of each
Supplemental Stock Option shall be not less than ten percent (10%) of the fair
market value of the stock subject to the option on the date the option is
granted.

      (c) The purchase price of stock acquired pursuant to an option shall be
paid, to the extent permitted by applicable statutes and regulations, either (i)
in cash at the time the option is exercised, or (ii) at the discretion of the
Board or the Committee, either at the time of the grant or exercise of the
option, (A) by delivery to the Company of shares of common stock of the Company
that have been held for the requisite period necessary to avoid a charge to the
Company's reported earnings and valued at the fair market value on the date of
exercise (determined by the closing sale price per share of Common Stock for
such date as reported by the New York Stock Exchange), (B) according to a
deferred payment or other arrangement (which may include, without limiting the
generality of the foregoing, the use of other common stock of the Company) with
the person to whom the option is granted or to whom the option is transferred
pursuant to subparagraph 7(d), or (C) in any other form of legal consideration
that may be acceptable to the Board or the Committee.  With regard to payment of
the purchase price of common stock of the Company received upon exercise of an
option granted under the Automatic Option Grant Program, payment shall be in the
form specified in paragraph 7(c)(i), in the form specified in paragraph
7(c)(ii)(A), or by a combination of such methods of payment.

         In the case of any deferred payment arrangement, interest shall be
payable at least annually and shall be charged at the minimum rate of interest
necessary to avoid the treatment as interest, under any applicable provisions of
the Code, of any amounts other than amounts stated to be interest under the
deferred payment arrangement.

      (d) An option shall not be transferable except by will or by the laws of
descent and distribution, and shall be exercisable during the lifetime of the
person to whom the option is granted only by such person.

      (e) The total number of shares of stock subject to an option may, but need
not, be allotted in periodic installments (which may, but need not, be equal).
From time to time during each of such installment periods, the option  may
become exercisable ("vest") with respect to some or all of the shares allotted
to that period, and if vested, may be exercised with respect to some or all of
the shares allotted to such period and/or any prior period as to which the
option was not fully exercised.  During the remainder of the term of the option
(if its term extends beyond the end of the installment periods), the option may
be exercised from time to time with respect to any shares then remaining subject
to the option.  The provisions of this subparagraph 7(e) are subject to any
option provisions governing the minimum number of shares as to which an option
may be exercised.  Each option granted pursuant to the Automatic Option Grant
Program shall remain 

                                      -3-
<PAGE>
 
unvested for six (6) months. On the day following the expiration of six (6)
months from the date of grant, each such option shall become fifty (50%) percent
vested, with the remaining shares subject to such options vesting in daily
installments of 1/365 of the total number of shares subject to such option.

      (f) The Company may as a condition of issuing any stock pursuant to the
Plan, require any person who is to acquire such stock, (1) to give written
assurances satisfactory to the Company as to such person's knowledge and
experience in financial and business matters and/or to employ a purchaser
representative reasonably satisfactory to the Company who is knowledgeable and
experienced in financial and business matters, and that he or she is capable of
evaluating, alone or together with the purchaser representative, the merits and
risks of exercising the option; and (2) to give written assurances satisfactory
to the Company stating that such person is acquiring the stock for such person's
own account and not with any present intention of selling or otherwise
distributing the stock.  These requirements, and any assurances given pursuant
to such requirements, shall be inoperative if (i) the issuance of the shares has
been registered under the Securities Act of 1933, as amended (the "Securities
Act"), or (ii) as to any particular requirement, a determination is made by
counsel for the Company that such requirement need not be met in the
circumstances under the then applicable securities laws.

      (g) An option shall terminate three (3) months after termination of the
optionee's employment or relationship as a consultant or director with the
Company or an Affiliate, unless (i) such termination is due to such person's
permanent and total disability, within the meaning of Section 422(c)(6) of the
Code, in which case the option may, but need not, provide that it may be
exercised at any time within one (1) year following such termination of
employment or relationship as a consultant or director; or (ii) the optionee
dies while in the employ of or while serving as a consultant or director to the
Company or an Affiliate, or within not more than three (3) months after
termination of such employment or relationship, in which case the option may,
but need not, provide that it may be exercised at any time within eighteen (18)
months following the death of the optionee by the person or persons to whom the
optionee's rights under such option pass by will or by the laws of descent and
distribution; or (iii) the option by its terms specifies either (A) that it
shall terminate sooner than three (3) months after termination of the optionee's
employment or relationship as a consultant or director, or (B) that it may be
exercised more than three (3) months after termination of such employment or
relationship with the Company or an Affiliate.  This subparagraph 7(g) shall not
be construed to extend the term of any option or to permit anyone to exercise
the option after expiration of its term, nor shall it be construed to increase
the number of shares as to which any option is exercisable from the amount
exercisable on the date of termination of the optionee's employment or
relationship as a consultant or director.

      (h) The option may, but need not, include a provision whereby the optionee
may elect at any time during the term of his or her employment or relationship
as a consultant or director with the Company or any Affiliate to exercise the
option as to any part or all of the shares subject to the option prior to the
stated vesting date of the option or of any installment or installments
specified in the option.  Any shares so purchased from any unvested installment
or option may be subject to a repurchase right in favor of the Company or to any
other restriction the Board or the Committee determines to be appropriate.


8.    COVENANTS OF THE COMPANY.
      ------------------------ 

      (a)  During the terms of the options granted under the Plan, the Company 
shall keep available at all times the number of shares of stock required to
satisfy such options.

     (b)  The Company shall seek to obtain from each regulatory commission or
agency having jurisdiction over the Plan such authority as may be required to
issue and sell shares of stock upon grant or exercise of Stock Awards under the
Plan; provided, however, that this undertaking shall not require the Company to
register under the Securities Act either the Plan, any Stock Award granted under
the Plan or any stock issued or issuable pursuant to any such Stock Awards. If,
after reasonable efforts, the Company is unable to obtain from any such
regulatory commission or agency the authority which counsel for the Company
deems necessary for the lawful issuance and sale of stock under the Plan, the
Company shall be relieved from any liability for failure to issue and sell stock
upon exercise of such Stock Awards unless and until such authority is obtained.

9.    USE OF PROCEEDS FROM STOCK.
      ---------------------------

                                      -4-
<PAGE>
 
      Proceeds from the sale of stock pursuant to Stock Awards granted under 
the Plan shall constitute general funds of the Company.

10.   MISCELLANEOUS.
      ------------- 

     (a)  The Board or the Committee shall have the power to accelerate the 
time at which a Stock Award may first be exercised or the time during which an
option or stock acquired pursuant to a Stock Award or any part thereof will
vest, notwithstanding the provisions in the Stock Award stating the time at
which it may first be exercised or the time during which it will vest.

     (b)  Neither a recipient of a Stock Award nor any person to whom a Stock 
Award is transferred under subparagraph 7(d) or 8(b) shall be deemed to be the
holder of, or to have any of the rights of a holder with respect to, any shares
subject to such Stock Award unless and until such person has satisfied all
requirements for exercise of the Stock Award pursuant to its terms.

     (c)  Nothing in the Plan or any instrument executed or Stock Award granted
pursuant thereto shall confer upon any eligible employee, consultant or director
any right to continue in the employ of the Company or any Affiliate (or to
continue acting as a consultant or director) or shall affect the right of the
Company or any Affiliate to terminate the employment or consulting relationship
or directorship of any eligible employee, consultant or director with or without
cause. In the event that a Stock Award recipient is permitted or otherwise
entitled to take a leave of absence, the Company shall have the unilateral right
to (i) determine whether such leave of absence will be treated as a termination
of employment for purposes of his or her Stock Award, and (ii) suspend or
otherwise delay the time or times at which the shares subject to the Stock Award
would otherwise vest.

     (d)  At the discretion of the Board or the Committee, the recipient may 
satisfy any federal, state or local tax withholding obligation relating to the
exercise of such Stock Award by any of the following means or by a combination
of such means: (1) tendering a cash payment; (2) authorizing the Company to
withhold from the shares of the common stock otherwise issuable to the
participant as a result of the exercise of the Stock Award a number of shares
having a fair market value less than or equal to the amount of the withholding
tax obligation; or (3) delivering to the Company owned and unencumbered shares
of the common stock having a fair market value less than or equal to the amount
of the withholding tax obligation.

11.   CANCELLATION AND RE-GRANT OF OPTIONS.
      ------------------------------------ 

     (a)  The Board or the Committee shall have the authority to effect, at any 
time and from time to time, with the consent of the affected option holders, (i)
the repricing of any or all outstanding options (excluding Incentive Stock
Options) under the Plan and/or (ii) the cancellation of any or all outstanding
options under the Plan and the grant in substitution therefor new options under
the Plan covering the same or different numbers of shares of Common Stock but
having an option price per share not less than ten percent (10%) of the fair
market value (one hundred percent (100%) of the fair market value in the case of
an Incentive Stock Option or, in the case of a ten percent (10%) stockholder (
as defined in subparagraph 5(c)), not less than one hundred and ten percent
(110%) of the fair market value) per share of Common Stock on the new grant
date.

12.   ADJUSTMENTS UPON CHANGES IN STOCK.
      --------------------------------- 

     (a)  If any change is made in the stock subject to the Plan, or subject to 
any Stock Award granted under the Plan (through merger, consolidation,
reorganization, recapitalization, stock dividend, dividend in property other
than cash, stock split, liquidating dividend, combination of shares, exchange of
shares, change in corporate structure or otherwise), the Plan and outstanding
Stock Awards will be appropriately adjusted in the class(es) and maximum number
of shares subject to the Plan and the class(es) and number of shares and price
per share of stock subject to outstanding Stock Awards.

     (b)  In the event of:  (1) a dissolution or liquidation of the Company; 
(2) a merger or consolidation in which the Company is not the surviving
corporation; (3) a reverse merger in which the Company is the surviving
corporation but the shares of the Company's common stock outstanding immediately
preceding the merger are converted by virtue of the merger into other property,
whether in the form of securities, cash or otherwise; or (4) any other capital
reorganization in

                                      -5-
<PAGE>
 
which more than fifty percent (50%) of the shares of the Company entitled to
vote are exchanged; then to the extent permitted by applicable law (i) any
surviving corporation shall assume any Stock Awards outstanding under the Plan
or shall substitute similar rights for those outstanding under the Plan, or (ii)
such Stock Awards shall continue in full force and effect. In the event any
surviving corporation refuses to assume or continue such Stock Awards, or to
substitute similar Stock Awards for those outstanding under the Plan, then, with
respect to Stock Awards held by persons then performing services as employees,
directors or consultants for the Company, the time during which such options may
be exercised shall be accelerated and the Stock Awards terminated if not
exercised prior to such event.

13.   AMENDMENT OF THE PLAN.
      --------------------- 

     (a)  The Board at any time, and from time to time, may amend the Plan.  
However, except as provided in paragraph 12 relating to adjustments upon changes
in stock, no amendment shall be effective unless approved by the stockholders of
the Company within twelve (12) months before or after the adoption of the
amendment, where the amendment will:

          (i)  Increase the number of shares reserved for issuance under the 
Plan;

          (ii)  Modify the requirements as to eligibility for participation in 
the Plan (to the extent such modification requires stockholder approval in order
for the Plan to satisfy the requirements of Section 422(b) of the Code); or

          (iii)  Modify the Plan in any other way if such modification requires 
stockholder approval in order for the Plan to satisfy the requirements of
Section 422(b) of the Code.

     (b)  It is expressly contemplated that the Board may amend the Plan in any
respect the Board deems necessary or advisable to provide eligible employees,
directors or consultants with the maximum benefits provided or to be provided
under the provisions of the Code and the regulations promulgated thereunder
relating to employee stock options and/or to bring the Plan and/or options
granted under it into compliance therewith.

     (c)  Rights and obligations under any Stock Award granted before amendment 
of the Plan shall not be altered or impaired by any amendment of the Plan unless
(i) the Company requests the consent of the person to whom the option was
granted and (ii) such person consents in writing.

14.   TERMINATION OR SUSPENSION OF THE PLAN.
      ------------------------------------- 

     (a)  The Board may suspend or terminate the Plan at any time.  Unless 
sooner terminated, the Plan shall terminate within ten (10) years from the date
the Plan is adopted by the Board or approved by the stockholders of the Company,
whichever is earlier. No Stock Awards may be granted under the Plan while the
Plan is suspended or after it is terminated.

     (b)  Rights and obligations under any Stock Award granted while the Plan 
is in effect shall not be altered or impaired by suspension or termination of
the Plan, except with the consent of the person to whom the Stock Award was
granted.

15.   EFFECTIVE DATE OF PLAN.
      ---------------------- 

      The Plan shall become effective as determined by the Board, but no Stock 
Award granted under the Plan shall be exercised unless and until the Plan has
been approved by the stockholders of the Company.
