                  Notes to Consolidated Financial Statements


1.  Operations

    Nitinol Medical Technologies, Inc. (the Company) designs, develops, and
    markets innovative medical devices that utilize advanced technologies and
    are delivered by minimally invasive procedures. The Company's products are
    designed to offer alternative approaches to existing complex treatments,
    thereby reducing patient trauma, shortening procedure, hospitalization and
    recovery times, and lowering overall treatment costs. The Company's patented
    medical devices include self-expanding stents, vena cava filters, and septal
    repair devices. At this time, the Company's stents have been commercially
    launched in Europe and in the United States for certain indications, its
    vena cava filters are marketed in the United States and abroad, and the
    CardioSEAL device is in the clinical trials stage in the U.S. and has begun
    commercial sales in certain European and other international markets. The
    Company is subject to a number of risks similar to those of other companies
    in this stage of development, including uncertainties regarding the
    development of commercially viable products, competition from alternative
    procedures and larger companies, dependence on key personnel and government
    regulation.

2.  Interim Financial Statements

    The accompanying Consolidated Financial Statements as of June 30, 1997 and
    for the three and six month periods then ended are unaudited. In
    management's opinion, these unaudited Consolidated Financial Statements have
    been prepared on the same basis as the audited Consolidated Financial
    Statements included in the Company's Annual Report as of December 31, 1996
    as filed on Form 10-K on March 12, 1997 and include all adjustments,
    consisting of only normal recurring adjustments, necessary for a fair
    presentation of the results for such interim periods. The results of
    operations for the three and six months ended June 30, 1997 are not
    necessarily indicative of the results expected for the fiscal year ending
    December 31, 1997.

3.  Cash and Cash Equivalents, Marketable Securities, and Long-Term
    Investments
 
  In accordance with Statement of Financial Accounting Standards (SFAS) No. 115,
  Accounting for Certain Investments in Debt and Equity Securities, the Company
  has classified certain of its marketable securities and long-term investments
  as held-to-maturity and certain of its marketable securities as available-for-
  sale.

1.  Cash and Cash Equivalents, Marketable Securities, and Long-Term
    Investments--(continued)

    Held-to-maturity securities represent those securities for which the Company
    has the intent and ability to hold to maturity and are reported at amortized
    cost. Available-for-sale securities represent those securities that do not
    meet the classification of held-to-maturity, are not actively traded and are
    reported at fair market value with any unrealized gains and losses included
    in stockholders' equity. There were no unrealized gains and losses at June
    30, 1997. The Company considers all investments with maturities of 90 days
    or less from the date of the purchase to be cash equivalents.

    Cash and cash equivalents, which are carried at cost and approximate market,
    consist of the following at:

5.  Depreciation and Amortization

    The Company provides depreciation and amortization by charges to operations
    using the straight-line method, which allocates the cost of property and
    equipment over the following estimated useful lives:

      Office furniture and equipment         5-10 Years
</TABLE> 
 
6.  Net Loss per Common and Common Equivalent Share

    Net loss per common and common equivalent share is based on the weighted-
    average number of shares of common stock and common stock equivalents
    outstanding during the respective periods. All shares of capital stock,
    options and warrants issued during the 12 months immediately preceding the
    initial public offering on October 2, 1996 were treated as if they had been
    outstanding for all periods presented in 1996, in accordance with the
    Securities and Exchange Commission rules and regulations, calculated under
    the treasury stock method and based on the offering price of $11.00 per
    share.

7.  In-Process Research and Development

    On May 29, 1997 the Company entered into an agreement to invest $2.3 million
    in Image Technologies Corporation (ITC) in exchange for 345,722 shares of
    ITC's $.01 par value convertible preferred stock, representing a 23%
    ownership interest in ITC. Under the terms of this agreement, the Company
    has extended ITC a credit line of up to $2 million of senior debt,
    convertible to convertible preferred stock at the option of the Company and
    equivalent to up to an additional 20% ownership of ITC. ITC may draw against
    this line of credit based upon meeting its approved business plan. The
    Company, however, has the right to advance all of the line and convert to
    convertible preferred stock at its option. The Company also has a 24 month
    option to purchase the remaining 57% of ITC for $24.5 million of which up to
    $8.5 million may be payable in cash. The option may be extended for an
    additional six months under certain conditions.

7.  In-Process Research and Development--(continued)

    ITC is a development stage company with no revenues to date. Due to the
    uncertainty regarding the realization for investment, the Company charged
    the amount of the purchase price and related acquisition costs to operations
    as in-process research and development.

8.  Restructuring Charge

    During the three months ended June 30, 1997, the Company reorganized its
    vena cava filter operations and brought the assembly of its straight-line
    vena cava filters in-house. In connection with this restructuring, the
    Company reduced staff and incurred other non-recurring costs. The $194,000
    restructuring charge in the accompanying statements of operations includes a
    non-cash charge of $112,000 for the accelerated vesting of certain stock
    options, accrued cash severance and benefits of $62,000, and $20,000 for the
    transfer of assembly technology. Other start-up costs related to the in-
    house assembly of the straight-line vena cava filter, including the training
    of manufacturing personnel and associated materials and overhead, are
    included in cost of goods sold in the accompanying statement of operations.

9.  Lease Finance Facility Agreement

    In June 1996, the Company entered into a one-year $1.5 million lease finance
    facility agreement with a bank under which the Company leases equipment at
    an interest rate that is 200 basis points above the bank's cost of funds.
    Leases under this agreement are payable in equal monthly installments over a
    period of 36-60 months and expire through November 2001. Upon the expiration
    of this agreement in June 1997, the Company entered into a new agreement
    with the bank that provides the Company with similar terms and the option to
    borrow up to $1 million through March 31, 1998. As of June 30, 1997, no
    borrowings were made under the $1 million agreement.

11.  New Accounting Standard

     In March 1997, the Financial Accounting Standards Board issued SFAS No.
     128, Earnings Per Share. SFAS No. 128 establishes standards for computing

     income (loss) per share.

and filed with the Securities and Exchange Commission on March 12, 1997.

Results of Operations

Three months ended June 30, 1997 compared with three months ended June 30, 1996

Revenues.  Revenues for the three months ended June 30, 1997 increased to $2.3
million from $1.3 million for the three months ended June 30, 1996 (a 77%
increase).  Product sales increased to $2.0 million for the three months ended
June 30, 1997 from $1.1 million for the three months ended June 30, 1996 (an 82%
increase).  The increase in product sales was due to increased unit sales of
vena cava filters, a 3% increase in the price of vena cava filters, the
commencement of sales of the CardioSEAL Septal Occluder in connection with
clinical trials which commenced at the end of September 1996, and the
commencement of commercial sales of the CardioSEAL Septal Occluder in June 1997
in certain European and other international markets.  The Company recorded
$250,000 in license fees from Boston Scientific Corporation ("Boston
Scientific") related to its stent technology in the three months ended June 30,
1997 representing a quarterly minimum royalty payment.  Revenues for the three
months ended June 30, 1996 included $187,500 in such quarterly minimum royalty
payments from Boston Scientific. Product development revenues from Boston
Scientific (which consist of reimbursement of certain costs incurred by the
Company) increased to $20,000 for the three months ended June 30, 1997 from
$14,000 for the three months ended June 30, 1996 due to increased collaboration
with Boston Scientific on stent development projects in 1997.

Cost of Product Sales.  Cost of product sales increased to $921,000 for the
three months ended June 30, 1997 from $546,000 for the three months ended June
30, 1996 (a 69% increase). The cost of product sales for the three months ended
June 30, 1997 includes sales of vena cava filters and CardioSEAL Septal
Occluders in connection with clinical trials and foreign commercial sales.  The
cost of product sales for the three months ended June 30, 1996 was entirely
related to sales of vena cava filters. Cost of product sales, as a percent of
product sales, decreased to 46% for the three months ended June 30, 1997 from
48% for the three months ended June 30, 1996.  This decrease is primarily
attributable to sales of the CardioSEAL Septal Occluder which has a lower cost
of product sales as a percent of sales than the vena cava filter.

Research and Development.  Research and development expenses increased to
$722,000 for the three months ended June 30, 1997 from $640,000 for the three
months ended  June 30, 1996 (a 13% increase).  The increase reflects an increase
in regulatory and clinical trial expenses for the CardioSEAL Septal Occluder
incurred in connection with clinical trials which commenced in September 1996,
as well as increased activity in the Company's development programs for vena
cava filters and other products under development.  Increased expenses resulted
primarily from increases in personnel and related costs, engineering expenses
and facilities related costs.  The Company received reimbursement from Boston
Scientific for $20,000 and $14,000 of these expenses in the three months ended
June 30, 1997 and 1996, respectively, which amounts are included in revenues.

General and Administrative.  General and administrative expenses increased to
$725,000 for the three months ended June 30, 1997 from $488,000 for the three
months ended June 30, 1996 (a 49% increase).  The increase consisted primarily
of increases in personnel and related costs,  legal and professional fees,
facilities costs, consulting expenses, investor relations costs, and computer
systems costs resulting from the Company's expanded scope of operations in 1997.

Selling and Marketing.  Selling and marketing expenses increased to $247,000 for
the three months ended June 30, 1997 from $55,000 for the three months ended
June 30, 1996 (a 349% increase).  The increase related primarily to the pre-
marketing activities related to the CardioSEAL Septal Occluder in connection
with clinical trials, and the commencement of commercial sales of the CardioSEAL
Septal Occluder in June 1997 in certain European and other international
markets.

In-Process Research and Development.  For the three months ended June 30, 1997,
the Company recorded a charge of $2.4 million for in-process research and
development related to the Company's investment in Image Technologies
Corporation on May 29, 1997.  See Note 7 of the accompanying Notes to
Consolidated Financial Statements.

Restructuring Charge.  During the three months ended June 30, 1997, the Company
reorganized its vena cava filter operations and brought the assembly of its
straight-line vena cava filters in-house.  In connection with this
reorganization, the Company recorded a restructuring charge of $194,000 in the
quarter ended June 30,1997.  See Note 8 of the accompanying Notes to
Consolidated Financial Statements.

Interest Income, Net.  Interest income, net was $384,000 for the three months
ended June 30, 1997 as compared to $76,000 for the three months ended June  30,
1996.  The increase was primarily due to the closing of the Company's initial
public offering of 3,150,000 shares of common stock in October 1996 resulting in
net proceeds to the Company of $31.2 million.

Income Taxes.  The Company had a provision for income taxes of $17,500 for the
three months ended June 30, 1997 which reflects the non-deductibility of the in-
process research and development and a portion of the $194,000 restructuring
charge recorded in the period, and income taxes provided in the three months
ended March 31, 1997.  There was no provision for income taxes for the three
months ended June 30, 1996 as the Company incurred an operating loss for that
period.

Six months ended June 30, 1997 compared with six months ended June 30, 1996

Revenues. Revenues for the six months ended June 30, 1997 increased to $4.4
million from $2.7 million for the six months ended June 30, 1996 (a 63%
increase). Product sales increased to $3.9 million for the six months ended June
30, 1997 from $2.0 million for the six months ended June 30, 1996 (a 95%
increase). The increase in product sales was primarily due to increased unit
sales of vena cava filters, a 3% increase in the price of vena cava filters, and
the commencement of sales of the CardioSEAL Septal Occluder in connection with
clinical trials which commenced at the end of September 1996, and the
commencement of commercial sales of the CardioSEAL Septal Occluder in June 1997
in certain European and other international markets. The Company recorded
$500,000 in license fees from Boston Scientific Corporation ("Boston
Scientific") related to its stent technology in the six months ended June 30,
1997 representing two quarterly minimum royalty payments of $250,000 each.
Revenues for the six months ended June 30, 1996 included $250,000 in milestone
payments and $375,000 in minimum royalty payments from Boston Scientific.
Product development revenues from Boston Scientific (which consist of
reimbursement of certain costs incurred by the Company) decreased to $50,000 for
the six months ended June 30, 1997 from $79,000 for the six months ended June
30, 1996 due to the completion of the Company's transfer of its stent technology
to Boston Scientific in November 1995 which resulted in a reduction of stent
development costs incurred by the Company on behalf of Boston Scientific in the
six months ended June 30, 1997 compared to the six months ended June 30, 1996.

Cost of  Product Sales.  Cost of product sales increased to $1.8 million for the
six months ended June 30, 1997 from $924,000 for the six months ended June 30,
1996 (a 95% increase). The cost of product sales for the six months ended June
30, 1997 includes sales of vena cava filters and CardioSEAL Septal Occluders in
connection with clinical trials and commercial sales.  The cost of product sales
for the six months ended June 30, 1996 was entirely related to sales of vena
cava filters. Cost of product sales, as a percent of product sales, remained
constant at 46% for the six months ended June 30, 1997 and 1996, respectively.

                                       15

Research and Development.  Research and development expenses increased to $1.5
million for the six months ended June 30, 1997 from $1.2 million for the six
months ended  June 30, 1996 (a 25% increase).  The increase reflects an increase
in regulatory and clinical trial expenses for the CardioSEAL Septal Occluder
incurred in connection with clinical trials which commenced in September 1996,
as well as increased activity in the Company's development programs for vena
cava filters and other products under development.  Increased expenses resulted
primarily from increases in personnel and related costs, engineering expenses
and facilities related costs.  The Company received reimbursement from Boston
Scientific for $50,000 and $79,000 of these expenses in the six months ended
June 30, 1997 and 1996, respectively, which amounts are included in revenues.

General and Administrative.  General and administrative expenses increased to
$1.4 million for the six months ended June 30, 1997 from $940,000 for the six
months ended June 30, 1996 (a 49% increase).  The increase consisted primarily
of increases in personnel and related costs,  legal and professional fees,
facilities costs, consulting expenses, investor relations costs, and computer
systems costs resulting from the Company's expanded scope of operations in 1997.

Selling and Marketing.  Selling and marketing expenses increased to $384,000 for
the six months ended June 30, 1997 from $103,000 for the six months ended June
30, 1996 (a 273% increase).  The increase related primarily to the pre-marketing
activities related to the CardioSEAL Septal Occluder in connection with clinical
trials, and the commencement of commercial sales of the CardioSEAL Septal
Occluder in June 1997 in certain European and other international markets.

In-Process Research and Development.  For the six months ended June 30, 1997,
the Company recorded a charge of $2.4 million for in-process research and
development related to the Company's investment in Image Technologies
Corporation on May 29, 1997.  See Note 7 of the accompanying Notes to
Consolidated Financial Statements.

Restructuring Charge.  During the six months ended June 30, 1997, the Company
reorganized its vena cava filter operations and brought the assembly of its
straight-line vena cava filters in-house.  In connection with this
reorganization, the Company recorded a restructuring charge of $194,000 in the
six months ended June 30, 1997.  See Note 8 of the accompanying Notes to

Interest Income, Net.  Interest income, net was $787,000 for the six months
ended June 30, 1997 as compared to $101,000 for the six months ended June  30,
1996 (a 679% increase).  The increase was primarily due to the receipt of $7.5
million in net proceeds from the sale of Convertible Preferred Stock in February
1996 and the closing of the Company's initial public offering of 3,150,000
shares of common stock in October 1996 resulting in net proceeds to the Company
of $31.2 million.

Income Taxes.  The Company had a provision for income taxes of $23,000 for the
six months ended June 30, 1997 which reflects the non-deductibility of the in-
process research and development and a portion of the $194,000 restructuring
charge recorded in the period.  There was no provision for income taxes for the
six months ended June 30, 1996 as the Company incurred an operating loss for
that period.

Liquidity and Capital Resources

In the six months ended June 30, 1997, the Company's operations utilized cash of
approximately $3.6 million of which $2.4 million was used to acquire the 23%
interest in Image Technologies Corporation (see Note 7 of in the accompanying
Notes to Consolidated Financial Statements) and $1.2 million was used for
working capital primarily related to sales of the CardioSEAL Septal Occluder in
connection with clinical trials and commercial sales in certain European and
other international markets and for increased vena cava filter sales.  In the
six months ended June 30, 1996, the Company's operations utilized cash of $1.1
million which was used primarily to fund an operating loss of $1.4 million and
for working capital.

Purchases and capitalized leases of property and equipment for use in its
research and development and general and administrative activities amounted to
$151,000 for the six months ended June 30, 1997.  In June 1996, the Company
entered into a one-year $1.5 million equipment lease line of credit agreement
without covenants.  Upon expiration of this agreement in June 1997, the Company
entered into a new agreement with similar terms that provides the Company with
the option to borrow up to $1 million through March 31,1998.  As of June 30,
1997, no borrowings were made under the $1 million agreement.

                                       17
<PAGE>
 
The Company is party to various other substantial contractual arrangements
including salaries and fees for current employees and consultants which are
likely to increase as additional agreements are entered into and additional
personnel are retained.  The Company also has committed to purchase certain
minimum quantities of the vena cava filter from a supplier through June 2001.
See Note 8 to the Notes to Consolidated Financial Statements included in the
Company's Annual Report on Form 10-K as filed with the Securities and Exchange
Commission on March 12, 1997.  All of these arrangements require cash payments
by the Company over varying periods of time.  Certain of these arrangements are
cancelable on short notice and certain require termination or severance payments
as part of any early termination.

The Company believes that its existing resources and cash flow from current
operations will be sufficient to fund its current level of operations and
planned new product development, including increased working capital
requirements and capital expenditures, for the foreseeable future.  The Company
expects to expend substantial resources to complete development of the Company's
products, seek regulatory clearances or approvals, build its marketing, sales
and manufacturing organizations and conduct further research and development.

The Company may require additional funds for its research and product
development programs, preclinical and clinical testing, operating expenses,
regulatory processes, manufacturing and marketing programs and potential
licenses and acquisitions.  Any additional equity financing may be dilutive to
stockholders, and debt financing, if available, may involve restrictive
covenants.  The Company's capital requirements will depend on numerous factors,
including the sales of its products, the progress of its research and
development programs, the progress of preclinical and clinical testing, the time
and cost involved in obtaining regulatory approvals, the cost of filing,
prosecuting, defending and enforcing any patent claims and other intellectual
property rights, competing technological and market developments, developments
and changes in the Company's existing research, licensing and other
relationships and terms of any collaborative, licensing and other arrangements
that the Company may establish.

a certificate (the "Certificate") signed by its President certifying as to the
Company's cumulative pre-tax losses ("Pre-Tax Losses") for the period from April

following receipt of the Certificate (the end of such 30-day period being
referred to herein as the "Option Extension Deadline") to elect to extend the
option exercise period for an additional six-month period. For purposes of the
foregoing, any amounts accrued by the Company for the payment of bonuses
pursuant to Section 3 of the employment agreements of even date herewith between
the Company and each of Robert Lee Thompson and James C. Torraco, and any

purchase.  The closing of the purchase of Stockholder Shares pursuant to this
Section 1.2(b) (the "Closing") shall occur at the place, on the date and at the
time designated by the Purchaser in its Exercise Notice, provided that if, at
the date of the Closing herein provided for, the conditions set forth in
Sections 1.4 and 1.5 shall not have been satisfied (or waived), the Purchaser
may postpone the Closing until a date within five business days after such
conditions are satisfied.  Any such postponement shall not relieve the
Stockholders of any liability for failure to meet the conditions specified in
Section 1.5 hereof.

     (c)  The Purchaser shall not be under any obligation to deliver an Exercise
Notice and may allow the Option to terminate without purchasing any Stockholder
Shares hereunder; provided, however, that once the Purchaser has delivered to
the Stockholders an Exercise Notice, subject to the terms and conditions of this
Agreement and the satisfaction of the provisions of Section 1.5 hereof, the
Purchaser shall be bound to effect the purchase as described in such Exercise
Notice.

                        PURCHASER RIGHT OF FIRST REFUSAL

     (a)  In the event the Purchaser does not exercise the Option, then, in such
event, during the 12-month period commencing on the date of expiration of the
Option, the Company shall not enter into any agreement for the (i) sale of all
or substantially all of the capital stock of the Company, (ii) merger of the
Company with or into, or the consolidation of the Company with, any other
corporation, or any similar combination with any other corporation or (iii)
sale, lease or disposition of all or substantially all of the Company's
properties or assets (any such transaction referred to as a "Purchase
Transaction"), unless in each such case the Company shall have first complied
with this Agreement.  The Company shall deliver to the Purchaser a written
notice of any proposed or intended Purchase Transaction (the "Offer"), which
Offer shall (i) identify and describe in reasonable detail the terms of the
proposed Purchase Transaction, (ii) describe in reasonable detail the price and
other terms of the proposed Purchase Transaction, (iii) identify by name the
persons or entities that will be parties to the proposed Purchase Transaction,
and (iv) offer to enter into an agreement with the Purchaser on the same terms
and conditions as the proposed Purchase Transaction.  The Purchaser shall have
the right, for a period of sixty (60) days following receipt of such Offer, to
exercise its right to enter into an agreement with the Company on the same terms
and conditions specified in the Offer.  The Offer by its term shall remain open
and irrevocable for such 60-day period.

     (b)  To accept the Offer, the Purchaser must deliver a written notice to
the Company, prior to the end of the 60-day period, setting forth its desire to
enter into an agreement with the Company at the price and upon the other terms
specified in the Offer.

     (c)  The obligation of the Purchaser to enter into an agreement with the
Company pursuant to the provisions of this Article VII is subject in all cases
to the preparation, execution and delivery by the Company and the Purchaser of
definitive agreements relating to such transaction reasonably satisfactory in
form and substance to the Purchaser and its counsel.  Each party agrees to
negotiate diligently and in good faith to enter into such definitive agreements.

     (d)  The rights of the Purchaser under this Article VII shall only apply in
the event that the proposed Purchase Transaction is related to, results from or
follows any change, modification or amendment of, or waiver of rights under, the
License Agreement of even date herewith by and between the Company and Robert
Lee Thompson.

               [LETTERHEAD OF JUNEWICZ & CO., INC. APPEARS HERE]

                                                        May 23, 1997

Image Technologies Corporation
1909 Central Drive, Suite 302
Bedford, TX 76021

Attention:   Mr. R. Lee Thompson
             President and CEO
Gentlemen:

     This letter agreement (the "Agreement") will confirm the arrangement under 
which Junewicz & Co., Inc. ("Junewicz") has been engaged by Image Technologies 
Corporation (the "Company") to act as its exclusive financial advisor in 
connection with the transactions being contemplated with Nitinol Medical 
Technologies, Inc. ("Nitinol").

     As the Company's financial advisor, Junewicz has introduced the Company and
other investors to Nitinol and has assisted the Company in structuring and 
negotiating the transactions being contemplated with Nitinol.

     The Company and Junewicz further agree as follows:

1.   Transactions Contemplated with Nitinol
     --------------------------------------

     The transactions being contemplated between the Company, R. Lee Thompson 
("Thompson"), James C. Torraco ("Torraco") and Nitinol, Curran Capital 
Management and John P. Curran (collectively "Curran") are as follows:

     At the first closing, the following transactions will occur:

     a)  Nitinol will purchase $2.3 million of Series A Preferred Stock 
         ("Preferred Stock") from the Company ("Transaction 1a");

     b)  Curran will purchase $300,000 of Common Stock ("Common Stock") from the
         Company ("Transaction 1b"); and

     c)  The Company will purchase $300,000 of Common Stock from Thompson and 
         Torraco ("Transaction 1c").

     Subsequent to the first closing, the following transactions may occur:

     d)  Nitinol will provide a credit line to the Company of up to $2.0 million
of senior debt (the "Revolving Credit Loan").  Nitinol will have the right to 
convert all or any portion of the amount drawn down under the Revolving Credit 
Line into additional shares of Preferred Stock of the Company.  Nitinol may 
also, at any time during the Option Period (defined as the period during Nitinol
may exercise its option to purchase all of the outstanding capital stock of the 
Company pursuant to the Stockholders Option Agreement (the "Purchase Option")), 
convert all or any

Page 2


           portion of any undrawn amounts under the Revolving Credit Loan into
           additional shares of Preferred Stock of the Company ("Transaction
           1d").

     e)    Nitinol will have the option to purchase all remaining shares of the
           Company for an additional $24.5 million at any time during the Option
           Period ("Transaction 1e").

2.   Fees and Expenses
     -----------------

     In consideration for its services hereunder, Junewicz shall receive 7,500 
shares of the Company's Common Stock as a retainer payment.  Such shares shall 
be issued on or before the closing of Transactions 1a, 1b and 1c.  In addition,
Junewicz shall be entitled to receive the following indicated compensation from
the indicated obligors at the closing of the respective transactions:

     a)    The Company shall pay to Junewicz a cash fee equal to 5% of the gross
           proceeds of any sale of Preferred Stock by the Company to Nitinol. In
           addition, the Company shall issue to Junewicz an amount of warrants
           equal to 5% of the number of shares of Preferred Stock sold by the
           Company to Nitinol, less the number of shares of Common Stock
           redeemed by the Company from Thompson and Torraco in Transaction 1c.
           (Transactions 1a and 1d)

     b)    The Company shall pay to Junewicz a cash fee equal to 6% of the gross
           proceeds of any sale of Common Stock by the Company to Curran or
           other investors originated by Junewicz. In addition, the Company
           shall issue to Junewicz an amount of warrants equal to 6% of the
           number of shares of Common Stock sold by the Company to Curran or
           other investors originated by Junewicz. (Transaction 1b)

     c)    If Nitinol purchases the remaining shares of the Company, the Company
           agrees to pay Junewicz an additional cash transaction fee equal to
           2.0% of the Aggregate Consideration paid to the Company's
           shareholders up to $25 million, and 1.5% of the Aggregate
           Consideration on the portion greater than $25 million. (Transaction
           1e)

     The warrants (to purchase Common Stock) issued to Junewicz under 
Transactions 1a, 1b and 1d shall have an exercise price equal to the price paid 
for the Preferred Stock or Common Stock by Nitinol, Curran or other investors 
originated by Junewicz and shall be exerciseable at any time for a period of 
five years from the date of the respective transactions. In the event of (i) an
initial public offering by the Company, or (ii) a reorganization, merger or sale
of the Company, the Company shall permit the "cashless exercise" of any warrants
granted to Junewicz in this Paragraph (i.e., the exercise of the warrants
without payment of the exercise price in cash with the result that Junewicz
receives upon exercise cash representing the difference between the exercise
price of the warrants and the initial public offering or sale price of the
Common Stock without requiring Junewicz to pay the exercise price in cash).

     For purposes of this agreement, the term "Aggregate Consideration" shall 
mean the total fair market value (on the date of payment) of all consideration 
(including cash, securities, property, all remaining debt on the Company's 
financial statements and other indebtedness and obligations assumed by Nitinol 
and any other form of consideration) paid or payable, or otherwise distributed,
directly or indirectly, to the Company or its security holders in connection
with Transaction 1e. In addition to the foregoing compensation, the Company
shall reimburse Junewicz promptly

upon request, for its reasonable out-of-pocket expenses, which may include fees
and disbursements of its legal counsel.

3.   Indemnification
     ---------------

     The Company jointly and severally agree to indemnify Junewicz in accordance
with the indemnification provisions (the "Indemnification Provisions") as set 
forth in Annex A to this Agreement, which is incorporated by reference into this
Agreement.

4.   Prior Representation of Nitinol by Junewicz
     -------------------------------------------

     The Company has been advised that Junewicz has performed investment banking
services for Nitinol within the past two years and has a continuing personal and
business relationship with Nitinol, its executive officers and with J.H. Whitney
& Co., a major shareholder of Nitinol.  In addition, the Company was advised 
after the engagement of Junewicz but before the execution of any definitive 
agreements relating to the transactions discussed herein that Junewicz holds
99,660 warrants in Nitinol. The Company hereby expressly consents to Junewicz,
representation of the Company notwithstanding the information set forth in this
Paragraph. In particular, the information that is set forth in this Paragraph
shall not constitute gross negligence or willful misconduct by Junewicz within
the meaning set forth in Annex A.

5.   Governing Law and Other Matters
     -------------------------------
 
     This agreement shall be governed by and construed in accordance with the 
Laws of the State of New York without regard to the conflict of laws principles 
thereof.

     Neither this Agreement nor any written advice (written or oral) rendered by
Junewicz in connection with this Agreement may be disclosed to any third party 
or circulated or referred to publicly without the prior written consent of 
Junewicz.

     Please confirm that the foregoing is in accordance with your understanding 
by signing and returning the enclosed duplicate copy of this Agreement, which 
shall thereupon constitute a binding agreement as of the date set forth above.

                                        Very truly yours,

                                        JUNEWICZ & CO., INC.

In the event that Junewicz becomes involved in any capacity in any action, 
proceeding or investigation brought by or against any person including 
stockholders of the Company, in connection with any matter referred to in this 
Agreement, the Company periodically will reimburse Junewicz for its legal and 
other expenses (including the cost of any investigation and preparation) 
incurred in connection therewith. The Company also will indemnify and hold 
harmless against any losses, claims, damages, expenses or liabilities to any 
such person in connection with any matter referred to in this Agreement, except 
to the extent that any loss, claim, damage or liability is judicially determined
to have resulted primarily from the gross negligence or willful misconduct of 
Junewicz in performing the services that are the subject of this Agreement. If 
for any reason the foregoing indemnification is unavailable to Junewicz or 
insufficient to hold it harmless, then the Company shall contribute to the 
amount paid or payable by Junewicz as a result of such loss, claim, damage or 
liability in such proportion as is appropriate to reflect the relative benefits
of the Company and the other stockholders on one hand and Junewicz on the other 
hand in the matters contemplated by this Agreement, as well as the relative 
fault of the Company on the one hand and Junewicz on the other hand with respect
to such loss, claim, damage or liability and any other relevant equitable 
considerations. The reimbursement, indemnity and contribution obligations of the
Company under this paragraph shall be in addition to any liability which the 
Company may otherwise have, including, without limitation, any liability which 
the Company may have to Junewicz pursuant to the Agreement and shall extend upon
the same terms and conditions to the controlling person of Junewicz, and shall 
be binding upon and inure to the benefit of any successors, assigns, heirs, and 
personal representatives of the Company, Junewicz, any such affiliate and any 
such person. The Company also agrees that neither Junewicz nor its control 
person shall have any liability to the Company or the stockholders of the 
Company for or in connection with any matter referred to in this Agreement 
except to the extent that any losses, claims, damages, liabilities or expenses 
incurred by the Company are judicially determined to have resulted primarily 
from the gross negligence or willful misconduct of Junewicz in performing the 
services that are subject to this Agreement. The foregoing provisions shall 
survive any termination or completion of the engagement provided by this 
Agreement and this Agreement shall be governed by and construed in accordance 
with the laws of the State of New York without regard to the conflict of laws 
principles thereof. The Company agrees that they will not settle or compromise 
or consent to the entry of any judgment in any pending or threatened claim, 
action, suit or proceeding in respect of which indemnification may be sought 
hereunder unless such settlement, compromise or consent includes an
unconditional release of Junewicz and the controlling person of Junewicz from
all liability arising out of such claim, action, suit or proceeding.

delivered, to the Lender:

            (a)    As soon as practicable, but in any event within two (2)
Business Days after Borrower becomes aware of the existence of any Default or
Unmatured Default, or any development or other information which could

not enter into any transaction for the purchase, sale or exchange of property or
the rendering of any service to or for any shareholder or director of the
Borrower, or any affiliate of such person or entity, unless such transactions

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

take such action, execute such documents, and provide such information as the
Lender may

                                       11
<PAGE>
 
from time to time reasonably request in order further to effect the transactions

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

            (a)    The Borrower will not create, incur, assume, guarantee or
become liable, contingently or otherwise, with respect to any indebtedness or
obligation, except (i) Indebtedness which is subordinated to the Obligations,
provided the terms of such Indebtedness, including the terms of subordination
- --------
thereof, are satisfactory to the Lender, in its sole discretion, in all
respects; (ii) current liabilities of the Borrower incurred in the ordinary
course of business consistent with past practice and not incurred through the
borrowing of money or the obtaining of credit (except credit on an open account
customarily extended); (iii) Indebtedness in respect of taxes or other
governmental charges being contested in good faith by the appropriate
proceedings; (iv) operating leases entered into by the Borrower in the ordinary
course, provided such operating leases shall not cause a Default herein; and

(vi) such other Indebtedness described on Schedule 6.5 hereto.
                                          ------------

            (b)    The Borrower will not create, incur or allow to be created or

described on Schedule 6.5 hereto.
             ------------        

     6.6.   Issuance of Securities.  Borrower will not authorize or issue, or
            ----------------------                                           
enter into any agreement for the authorization or issuance of, any shares of any

subscribe for, purchase or otherwise acquire common stock or other capital stock
of the Borrower or any evidences of indebtedness, shares or other securities
directly or indirectly convertible into or exchangeable or exercisable for

the Company and Junewicz (and shares of Common Stock issuable upon exercise
thereof).

     6.7    Insurance.  Borrower agrees to keep all of the Collateral insured
            ---------
with coverages in amounts not less than usually carried by one engaged in a like
business (and in any event not less than that required by Lender), naming the
Lender as a loss payee, and payable to the Lender and Borrower, as their
interests may appear. Borrower hereby appoints Lender as attorney-in-fact for
Borrower in obtaining, adjusting, settling and cancelling such insurance and
endorsing any drafts. As further assurance for the payment and performance of
the Obligations, Borrower hereby

                                       12
<PAGE>
 
assigns to Lender all sums, including returned or unearned premiums, that may
become payable under any policy of insurance on the Collateral, and Borrower
hereby directs each insurance company issuing any such policy to make payment of
such sums directly to Lender.
 
     6.8.   Inspection.  Borrower will keep accurate and complete records of the
            ----------                                                          
Collateral, and Lender or any of its agents shall have the right, upon
reasonable notice, to inspect the Collateral wherever located and to visit
Borrower's place or places of business, at intervals to be determined by Lender
and without Borrower's hindrance or delay, to inspect, audit, check and make
extracts from any copies of books, records, journals, orders, receipts and
correspondence that relate to the Collateral or to the general financial
condition of Borrower.  Lender may temporarily remove any of the Borrower's
records for the purpose of having copies made thereof.

     6.9.   Taxes.  Borrower will pay all real and personal property taxes,
            -----                                                          
assessments and charges as well as all franchise, income, unemployment, old age
benefit, withholding, sales and other taxes assessed against it, or payable by
it at such times and in such manner as to prevent any penalty from accruing or
any lien or charge from attaching to its property, and will furnish the Lender
upon request, receipts, or other evidence that deposits or payments have been
made.

     6.10.  Sales.  Borrower will not sell or dispose of any of its assets,
            -----                                                          
including the Collateral, except in the ordinary and usual course of its
business.
 
     6.11.  Reimbursement.  Borrower will reimburse Lender on demand for any
            -------------                                                   
sums paid or advanced by Lender to satisfy any tax, lien or security interest or
other encumbrance on the Collateral, to provide insurance on the Collateral or
to pay for the maintenance and preservation of the Collateral; provided however,
                                                               -------- ------- 
that Lender shall not be obligated to make any such payments or deposits.  Any
such sums paid or advanced by Lender shall be deemed secured by the Collateral
and constitute part of the Obligations.

                                   DEFAULTS

to it under the Federal bankruptcy laws as now or hereafter in effect, (ii) make
an assignment for the benefit of creditors, (iii) apply for, seek, consent to,
acquiesce in, or have appointed for it or any substantial portion of its
property a receiver, custodian, trustee, examiner, liquidator or similar

bankruptcy, insolvency or reorganization or relief of debtors or fail to file an
answer or other pleading denying the material allegations of any such proceeding
filed against it, (v) take any corporate action to authorize or effect any of
the foregoing actions set forth in this Section 7.5.

     7.6.   This Agreement shall for any reason fail to create a valid and
perfected security interest in any collateral purported to be covered hereby,

to assert the invalidity or unenforceability of this Agreement.


                                 ARTICLE VIII

                ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES
                ----------------------------------------------

     8.1.   Acceleration.  If any Default described in Sections 7.4 or 7.5
            ------------
occurs with respect to the Borrower, the Obligations shall immediately become
due and payable without any election, notice or action on the part of the
Lender. If any other Default occurs, the Lender may declare the Obligations to
be due and payable, whereupon the

                                       14
<PAGE>
 
Obligations shall become immediately due and payable, without presentment,
demand, protest or notice of any kind, all of which the Borrower hereby
expressly waives.

     8.2.   Amendments.  The Lender and the Borrower may enter into written
            ----------                                                     
agreements supplemental hereto for the purpose of adding or modifying any
provisions to the Loan Documents or changing in any manner the rights of the
Lender or the Borrower hereunder or waiving any Default hereunder.  To be
effective, any such amendment or waiver must be in writing and signed by the
Lender and the Borrower.

     8.3.   Preservation of Rights; No Adverse Impact.  No delay or omission of
            -----------------------------------------                          
the Lender to exercise any right under this Agreement or any of the Loan
Documents, shall impair such right or be construed to be a waiver of any Default
or an acquiescence therein.  Any single or partial exercise of any such right
shall not preclude other or further exercise thereof or the exercise of any
other right, and no waiver, amendment or other variation of the terms,
conditions or provisions of the Loan Documents, whatsoever shall be valid unless
in writing signed by the Lender, and then only to the extent in such writing
specifically set forth.  All remedies contained in the Loan Documents, or by law
afforded shall be cumulative and all shall be available to the Lender until the
Obligations have been paid in full.

     8.4.   Remedies.
            -------- 

            (a)    Upon the occurrence of a Default, the Lender may proceed to
protect and enforce the Lender's rights by suit in equity, action of law and/or
other appropriate proceeding either for specific performance of any covenant or
condition contained in this Agreement, any Loan Document or in any instrument or
document delivered to the Lender pursuant hereto, or in the exercise of any
rights, remedies or powers granted in this Agreement, any Loan Document and/or
any such instrument or document.

            (b)    The Lender may enter and take possession of all Collateral
and the premises on which they are located, and in the Lender's sole discretion
operate and use Borrower's equipment, whether or not Collateral hereunder,
complete work in process, without being liable to Borrower on account of any
losses, damage or depreciation that may occur as a result thereof so long as
Lender shall act reasonably and in good faith; and at the Lender's option and
without notice to Borrower (except as specifically herein provided) Lender may
sell, lease, assign and deliver the whole or any part of the Collateral, or any
substitute therefor or any addition thereto, at public or private sale, for
cash, upon credit, or for future delivery, at such prices and upon such terms as
Lender deems advisable, including without limitation, the right to sell or lease
in conjunction with other property, real or personal, and allocate the sale or
lease proceeds among the items of property sold without the necessity of the
Collateral being present at any such sale or lease, or in view of prospective
purchasers thereof.

                                       15
<PAGE>
 
Lender shall give Borrower at least ten (10) days' notice by hand delivery or by
United States first-class mail, postage prepaid (in which event notice shall be
deemed to have been given when so deposited in the mail), to the address
specified herein, of the time and place of any public or private sale or other
disposition unless the Collateral is perishable, threatens to decline speedily
in value, or is the type customarily sold in a recognized market.  Upon such
sale, Lender may become the purchaser of the whole or any part of the
Collateral, discharged from all claims and free from any right of redemption.
In case of any such sale by Lender of all or any of said Collateral on credit or
for future delivery, property so sold may be retained by Lender until the
selling price is paid by the purchaser.  Lender shall incur no liability in case
of the failure of the purchaser to take up and pay for the property so sold.  In
case of any such failure, the said property may again be sold.
 
            (c)    The Lender, for a term to commence on the date of the
occurrence of a Default and continuing thereafter until all debts and
Obligations of any kind or character owing from Borrower to Lender are fully
paid and discharged, may enter and use all premises or places of business which
Borrower presently has or may hereafter have and where any of said Collateral
may be located, and the Lender may use all machinery and equipment owned or
leased by Borrower and all goodwill, patent rights, trade names, or logos,
whether or not Collateral hereunder.
 
            (d)    Borrower will assemble the Collateral in a single location at
a place to be designated by Lender and make the Collateral at all times secure
and available to Lender.
 
            (e)    Following the occurrence of a Default, at Borrower's expense,
the Lender in its own name or in the name of others may communicate with account
debtors in order to verify with them to Lender's satisfaction the existence,
amount and terms of any accounts or contract rights and also notify account
debtors that Collateral has been assigned to Lender and that payments shall be
made directly to Lender. Upon request of Lender, Borrower will so notify such
account debtors and will indicate on all billings to such account debtors that
their accounts must be paid to Lender. Borrower does hereby appoint Lender and
its agents as Borrower's attorney-in-fact: to collect, compromise, endorse, sell
or otherwise deal with the Collateral or proceeds thereof in its own name or in
the name of the Borrower; to endorse the name of Borrower upon any notes,
checks, drafts, money orders, or other instruments, documents, receipts or
Collateral that may come into its possession and to apply the same in full or
part payment of any amounts owing to Lender; to sign and endorse the name of
Borrower upon any documents, instruments, drafts against account debtors,
assignments, verifications and notices in connection with Accounts, and any
instrument or document relating thereto or to Borrower's rights therein; and to
give written notice to any office and officials of the United States Post Office
to effect such change or changes of address that all mail addressed to Borrower
may be delivered directly to Lender. Borrower hereby grants to its said 
attorney-in-fact full power to do any and

                                       16
<PAGE>
 
all things necessary to be done in and about the premises as fully and
effectually as Borrower might or could do, and hereby ratifies all that its
attorney-in-fact shall lawfully do or cause to be done by virtue hereof.  This
power of attorney is coupled with an interest and is irrevocable for the term of
this Agreement for all transactions hereunder and thereafter as long as Borrower
may be indebted to Lender.

     8.5.   Application of Proceeds.  Any and all proceeds of any Collateral
            ------------------------                                        
realized or obtained by the Lender upon exercise of its rights and remedies
hereunder, shall be applied to the amounts outstanding under this Agreement or
any other Loan Document, after payment of any and all costs and expenses, fees
and commissions and taxes of such sale, collection or other realization, in
accordance with the following:

     (a)    Any and all proceeds of any Collateral shall first be applied to the
            payment of any and all expenses, charges or other amounts which may
            be due and owing under this Agreement or the Loan Documents; and

     (b)    Any and all proceeds of any Collateral remaining after application
            as provided in paragraph (a) above shall first be applied to the
            payment of principal, interest or charges outstanding under the
            Revolving Credit Loans or under the Loan Documents; and

     (c)    Any surplus remaining after application as provided in paragraphs
            (a) and (b) above shall be paid to the Borrower, or its successors
            or assigns, or to whomsoever may be lawfully entitled to receive the
            same.

     8.6    Remedies Cumulative.  All remedies available under this Agreement

                                  CONVERSION
                                  ----------

     9.     Optional Conversion.  Any Revolving Credit Loan and any amount
            -------------------                                           
available under the Revolving Credit Commitment shall be subject to optional
conversion, at the Lender's option, as set forth below (the "Conversion
Rights"):

     9.1    Right to Convert.  The outstanding principal amount of any Revolving
            ----------------                                                    
Credit Loan shall be convertible, at the option of the Lender, at any time and
from time to time prior to the expiration of the Option Period, into fully paid
and nonassessable shares of Series A Preferred in accordance with the provisions
set forth below.  In addition, the Lender may, at its option and at any time and
from time to time prior to the expiration of the Option Period, make additional
Revolving Credit Loans to the Borrower, up to the amount of the Revolving Credit
Commitment, and

                                       17
<PAGE>
 
convert the principal amount of any such additional Revolving Credit Loan into
fully paid and nonassessable shares of Series A Preferred.  In the event the
principal amount of the Revolving Credit Loans to be converted equals $2,000,000
(i.e., the initial Revolving Credit Commitment), such Revolving Credit Loans
shall be convertible into 548,090 shares of Series A Preferred (such that after
giving effect to the issuance of such shares of Series A Preferred, the Lender
shall hold, in the aggregate, shares of Common Stock (including all shares of
Series A Preferred held by the Lender (whenever acquired) on an as-converted
basis) representing 43% of the outstanding capital stock of the Borrower).  For
the purposes hereof, "outstanding capital stock" shall include the shares of
Common Stock issuable upon exercise of the Junewicz Warrants, but exclude (i)
any shares of Common Stock issuable upon exercise of outstanding stock options
and (ii) any shares reserved for the grant of stock options in the future.  In
the event the principal amount of the Revolving Credit Loans to be converted is
less than $2,000,000, the number of shares of Series A Preferred into which such
Revolving Credit Loans shall be convertible shall be equal to one percent of the
outstanding capital stock of the Borrower (after giving effect to any conversion
hereunder) for each $100,000 in principal amount of Revolving Credit Loans so
converted.

     9.2    Fractional Shares.  No fractional shares of Series A Preferred shall
            -----------------                                                   
be issued upon conversion of any Revolving Credit Loan, but the Revolving Credit
Note will be marked to reflect a credit for the amount of the Revolving Credit
Loan converted in respect of which any fraction of a share would otherwise be
issuable upon conversion of such Revolving Credit Loan.  Such credit shall be
based on the fair market value of the Series A Preferred at the time of
conversion of any Revolving Credit Loan, as determined in good faith by the
Board of Directors.

     9.3    Mechanics of Conversion.
            ----------------------- 

            (a)    In order for the Lender to convert any Revolving Credit Loan
or other amount available under the Revolving Credit Commitment into shares of
Series A Preferred, the Lender shall deliver to the Borrower, during usual
business hours at the Borrower's principal executive offices, written notice of
its election to convert the principal amount of any Revolving Credit Loans, or
the portion thereof specified in such notice, into shares of Series A Preferred.
Such notice shall also state the name or names (and addresses) in which the
Lender wishes the certificate or certificates for shares of Series A Preferred
which shall be issuable on such conversion to be issued. Such conversion shall
be deemed to have been made at the time the notice specified above shall have
been received by the Borrower at its principal executive office (the "Conversion
Date"), and the holder in whose name any certificate or certificates for shares
of Series A Preferred shall be issuable upon such conversion shall be deemed to
have become on the Conversion Date the holder of record of the shares
represented thereby. The Borrower shall, as soon as practicable after the
Conversion Date (and, in any event, within five Business Days), issue and
deliver to the Lender, or to its

                                       18
<PAGE>
 
nominees, a certificate or certificates for the number of shares of Series A
Preferred to which the Lender shall be entitled.  If less than the entire
outstanding principal amount of the Revolving Credit Loans is being converted,
the Revolving Credit Note shall promptly be marked to reflect a credit for the
amount of the Revolving Credit Loans so converted.

            (b)    The Lender shall, at all times prior to the expiration of the
Option Period, reserve and keep available out of its authorized but unissued
stock, for the purpose of effecting the conversion of any Revolving Credit Loan
or amount available under the Revolving Credit Commitment, such number of its
duly authorized shares of Series A Preferred as shall from time to time be
sufficient to effect the conversion of any Revolving Credit Loan or any amount
available under the Revolving Credit Commitment.

            (c)    The Borrower shall pay any and all issue and other taxes that
may be payable in respect of any issuance or delivery of shares of Series A
Preferred pursuant to this Article IX.

     9.4    Mergers and Consolidations.  If, prior to the expiration of the
            --------------------------
Option Period, the Borrower shall at any time consolidate or merge with, or
otherwise combine with, another corporation (other than a merger or
consolidation in which the Borrower is the surviving corporation), the Lender
will thereafter be entitled to receive, upon the conversion hereof, the
securities or property to which a holder of the number of shares of Series A
Preferred then deliverable upon the conversion of the Revolving Credit Loans
would have been entitled upon such consolidation, merger or combination, and the
Borrower shall take such steps in connection with such consolidation, merger or
combination as may be necessary to ensure that the provisions hereof shall
thereafter be applicable, as nearly as reasonably may be, in relation to any
securities or property thereafter deliverable upon the conversion of any
Revolving Credit Loan or amount available under the Revolving Credit Commitment.

     9.5    Accrued Interest.  Upon the conversion of any Revolving Credit Loan,
            ----------------                                                    
the Borrower shall not be required to pay any accrued but unpaid interest on the
amount so converted up to the Conversion Date.

     9.6    Securities Act of 1933.  Upon conversion of any Revolving Credit
            ----------------------
Loan, the Lender may be required to execute and deliver to the Borrower an
instrument, in form satisfactory to the Borrower, representing that the shares
issuable upon conversion of the Revolving Credit Loan are being acquired for
investment and not with a view to distribution within the meaning of the
Securities Act of 1933, as amended.

this Note may be prepaid or its maturity date accelerated. This Note is secured
pursuant to the Loan and Security Agreement and a Guarantee, each of even date
herewith, as more specifically described in the Loan and Security Agreement, and
reference is made thereto for a statement of the terms and provisions thereof.
Capitalized terms used herein and not otherwise defined herein are used with the
meanings attributed to them in the Loan and Security Agreement.

     The Lender shall, and is hereby authorized to, record on the schedule
attached hereto, or to otherwise record in accordance with its usual practice,
the date and amount of the Revolving Credit Loan, the date and amount of each
principal payment hereunder and the date of conversion of any principal amount
of any Revolving Credit Loan into shares of Series A Preferred.

     The outstanding principal amount of any Revolving Credit Loan shall be
convertible, at the option of the Lender, at any time and from time to time
prior to the expiration of the Option Period, into fully paid and nonassessable
shares of Series A Preferred in accordance with the provisions set forth in the
Loan and Security Agreement. In addition, the Lender may, at its option and at
any time and from time to time prior to the expiration of the Option Period,
make additional Revolving Credit Loans to the Lender, up to the amount of the
Revolving Credit Commitment, and convert the principal amount of any such
additional Revolving Credit Loan into fully paid and nonassessable shares of
Series A Preferred.

     If any payment of principal or interest is not made when due hereunder, or
if any other event of Default shall occur for any reason, or if the Loan and
Security Agreement shall be terminated or not renewed for any reason whatsoever,
then and in any such event, in addition to all rights and remedies of Lender
under the Loan and Security Agreement or any Loan Document, applicable law or
otherwise, all such rights and remedies being cumulative and enforceable
alternatively, successively and concurrently, Lender may, at its option, declare
any and all of the Borrower's Obligations to be due and payable, whereupon the
then unpaid balance thereof, together with all interest accrued thereon or
expenses incurred in connection therewith shall forthwith become due and
payable, together with all interest accruing thereafter at the rate of interest
upon Default until the indebtedness evidenced by this Note is 
<PAGE>
 
paid in full, plus all costs and expenses of collection hereof, including,
without limitation, reasonable attorneys' fees and expenses.

     Borrower shall pay all Lender's costs and expenses (including, without
limitation, all reasonable attorneys' fees and expenses) incurred in connection
with the enforcement of or preservation of rights under this Revolving Credit
Note on the terms provided in the Loan and Security Agreement.

     No delay or omission on the part of the Lender in exercising any right
hereunder shall operate as a waiver of such right or of any other right of
Lender, nor shall any delay, omission or waiver on any one occasion be deemed a
bar to or waiver of the same or any other right on any future occasion.  The
Borrower and every indorser or guarantor of this Revolving Credit Note
regardless of the time, order or place of signing waives presentment, demand,
protest and notices of every kind and assents to any extension or postponement
of the time of payment or any other indulgence, to any substitution, exchange or
release of collateral, and to the addition or release of any other party or
person primarily or secondarily liable.

     None of the terms or provisions of this Revolving Credit Note may be
excluded, modified, or amended except by a written instrument duly executed on
behalf of the holder expressly referring hereto and setting forth the provision
so excluded, modified or amended. This Revolving Credit Note shall be binding
upon the successors and assigns of the Borrower and inure to the benefit of
Lender and its successors, endorsees and assigns. If any term or provision of
this Revolving Credit Note shall be held to be invalid or unenforceable, in
whole or in part in any jurisdiction, then such invalidity or unenforceability
shall only effect such term or provision, and shall not effect such term or
provision in any other jurisdiction or any other term or provision of this
Revolving Credit Note.

     BORROWER AGREES THAT ANY SUIT FOR THE ENFORCEMENT OF THIS NOTE OR ANY OF
THE OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE COMMONWEALTH OF
MASSACHUSETTS OR ANY FEDERAL COURT SITTING THEREIN AND CONSENTS TO THE
NONEXCLUSIVE JURISDICTION OF SUCH COURTS AND SERVICE OF PROCESS IN ANY SUCH SUIT
BEING MADE UPON THE BORROWER AT THE ADDRESS PROVIDED BELOW THE BORROWER'S
EXECUTION HEREOF. BORROWER HEREBY WAIVES ANY OBJECTION THAT IT MAY NOW OR
HEREAFTER HAVE TO THE VENUE OF ANY SUCH SUIT OR ANY SUCH COURT OR THAT SUCH SUIT
IS BROUGHT IN AN INCONVENIENT COURT.

     Borrower hereby waives its right to a jury trial in any judicial proceeding
involving, directly or indirectly, any matter (whether sounding in tort,
contract or otherwise) in any way arising out of, related to, or connected with
this Revolving Credit Note, the Loan and Security Agreement or any Loan Document
or the relationship established thereunder.

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

     marks and with the processing of the patents and marks, (ii) at Guarantor's
     sole cost, expense, and risk, pursue the prompt, diligent, processing of

     The Guarantor agrees to reimburse NMT on demand for any and all
     expenditures so made. NMT shall have no obligation to the Guarantor to make

     of any default, unless otherwise specified in the Loan and Security
     Agreement.

           8.2.  NMT's Obligations and Duties.  Anything herein to the contrary
                 ----------------------------                                  
     notwithstanding, the Guarantor shall remain liable under each contract or
     agreement comprised in the Collateral to be observed or performed by the
     Guarantor thereunder. NMT shall not have any obligation or liability under
     any such contract or agreement by reason of or arising out of this
     Agreement or the receipt by NMT of any payment relating to any of the
     Collateral, nor shall NMT be obligated in any manner to perform any of the
     obligations of the Guarantor under or pursuant to any such contract or
     agreement, to make inquiry as to the nature or sufficiency of any payment
     received by NMT in respect of the Collateral or as to the sufficiency of
     any performance by any party under any such contract or agreement, to
     present or file any claim, to take any action to enforce any performance or
     to collect the payment of any amounts which may have been assigned to NMT
     or to which NMT may be entitled at any time or times.

     9.    Further Assurances.  The Guarantor, at its own expense, shall do,
           ------------------

Commercial Code, as applicable in each relevant jurisdiction, with respect to
certificated and uncertificated securities.

     10.   Power of Attorney.
           ----------------- 

           10.1. Appointment and Powers of NMT. The Guarantor hereby irrevocably
                 -----------------------------
     constitutes and appoints NMT and any officer or agent thereof, with full
     power of substitution, as its true and lawful attorneys-in-fact with full
     irrevocable power and authority in the place and stead of the Guarantor or
     in NMT's own name, for the purpose of carrying out the terms of this
     Agreement, to take any and all appropriate action and to execute any and
     all documents and instruments that may be necessary or desirable to
     accomplish the purposes of this Agreement and, without limiting the
     generality of the foregoing, hereby gives said attorneys the power and
     right, on behalf of the Guarantor, without notice to or assent by the
     Guarantor, to do the following:

                 (a)   upon the occurrence and during the continuance of an
           event of Default, generally to sell, transfer, pledge, make any
           agreement with respect to or otherwise deal with any of the
           Collateral in such manner as is consistent with the Massachusetts
           Uniform Commercial Code and as fully and completely as though NMT
           were the absolute owner thereof for all purposes, and to do at the
           Guarantor's expense, at any time, or from time to time, all acts and
           things which NMT deems necessary to protect, preserve or realize upon
           the Collateral and NMT's security interest therein, in order to
           effect the intent of this Agreement, all as fully and effectively as
           the Guarantor might do, including, without limitation, (i) the filing
           and prosecuting of registration and transfer applications with the
           appropriate federal or local agencies or authorities with respect to
           trademarks, copyrights and patentable inventions and processes, (ii)
           upon written notice to the Guarantor, the exercise of voting rights
           with respect to voting securities, which rights may be exercised, if
           NMT so elects, with a view to causing the liquidation in a
           commercially reasonable manner of assets of the issuer of any such
           securities and (iii) the execution, delivery and recording, in
           connection with any sale or other disposition of any Collateral, of
           the endorsements, assignments or other instruments of conveyance or
           transfer with respect to such Collateral; and

                 (b)   to file such financing statements with respect hereto,
           with or without the Guarantor's signature, or a photocopy of this
           Agreement in substitution for a financing statement, as NMT may deem
           appropriate and to execute in the Guarantor's name such financing
           statements and amendments thereto and continuation statements which
           may require the Guarantor's signature.

           10.2. Ratification by Guarantor.  To the extent permitted by law, the
                 -------------------------                                      
     Guarantor hereby ratifies all that said attorneys shall lawfully do or
     cause to be done by virtue hereof. This power of attorney is a power
     coupled with an interest and shall be irrevocable.

           10.3  No Duty on NMT.  The powers conferred on NMT hereunder are
                 --------------
     solely to protect its interests in the Collateral and shall not impose any
     duty upon it to exercise any such powers. NMT shall be accountable only for
     the amounts that it actually receives as a result of the exercise of such
     powers and neither it nor any of its officers, directors, employees or
     agents shall be responsible to the Guarantor for any act or failure to act,
     except for NMT's own gross negligence or willful misconduct.

     11.   Remedies.  If an event of Default shall have occurred and be
           --------                                                    
continuing, NMT may, without notice to or demand upon the Guarantor, declare
this Agreement to be in default, and NMT shall thereafter have in any
jurisdiction in which enforcement hereof is sought, in addition to all other
rights and remedies, the rights and remedies of a secured party under the
Uniform Commercial Code, including, without limitation, the right to take
possession of the Collateral, and for that purpose NMT may, so far as the
Guarantor can give authority therefor, enter upon any premises on which the
Collateral may be situated and remove the same therefrom.  NMT may in its
discretion require the Guarantor to assemble all or any part of the Collateral
at such location or locations within the state(s) of the Guarantor's principal
office(s) or at such other locations as NMT may designate. Unless the Collateral
is perishable or threatens to decline speedily in value or is of a type
customarily sold on a recognized market, NMT shall give to the Guarantor at
least five Business Days prior written notice of the time and place of any
public sale of Collateral or of the time after which any private sale or any
other intended disposition is to be made.  The Guarantor hereby acknowledges
that five Business Days prior written notice of such sale or sales shall be
reasonable notice.  In addition, the Guarantor waives any and all rights that it
may have to a judicial hearing in advance of the enforcement of any of NMT's
rights hereunder, including, without limitation, its right following an event of
Default to take immediate possession of the Collateral and to exercise its
rights with respect thereto.

     12.   No Waiver, etc.  The Guarantor waives demand, notice, protest, notice
           --------------                                                       
of acceptance of this Agreement, notice of loans made, credit extended,
Collateral received or delivered or other action taken in reliance hereon and
all other demands and notices of any description.  With respect to both the
Obligations and the Collateral, the Guarantor assents to any extension or
postponement of the time of payment or any other indulgence, to any
substitution, exchange or release of or failure to perfect any security interest
in any Collateral, to the addition or release of any party or person primarily
or secondarily liable, to the acceptance of partial payment thereon and the
settlement, compromising or adjusting of any thereof, all in

                                      -5-
<PAGE>
 
such manner and at such time or times as NMT may deem advisable.  NMT shall have
no duty as to the collection or protection of the Collateral or any income
thereon, nor as to the preservation of rights against prior parties, nor as to
the preservation of any rights pertaining thereto.  NMT shall not be deemed to
have waived any of its rights upon or under the Obligations or the Collateral
unless such waiver shall be in writing and signed by NMT.  No delay or omission
on the part of NMT in exercising any right shall operate as a waiver of such
right or any other right.  A waiver on any one occasion shall not be construed
as a bar to or waiver of any right on any future occasion.  All rights and
remedies of NMT with respect to the Obligations or the Collateral, whether
evidenced hereby or by any other instrument or papers, shall be cumulative and
may be exercised singularly, alternatively, successively or concurrently at such
time or at such times as NMT deems expedient.

     13.   Marshalling.  NMT shall not be required to marshal any present or
           -----------                                                      
future collateral security (including but not limited to this Agreement and the
Collateral) for, or other assurances of payment of, the Obligations or any of
them or to resort to such collateral security or other assurances of payment in
any particular order, and all of its rights hereunder and in respect of such
collateral security and other assurances of payment shall be cumulative and in
addition to all other rights, however existing or arising.  To the extent that
it lawfully may, the Guarantor hereby agrees that it will not invoke any law
relating to the marshalling of collateral which might cause delay in or impede
the enforcement of NMT's rights under this Agreement or under any other
instrument creating or evidencing any of the Obligations or under which any of
the Obligations is outstanding or by which any of the Obligations is secured or
payment thereof is otherwise assured, and, to the extent that it lawfully may,
the Guarantor hereby irrevocably waives the benefits of all such laws.

     14.   Proceeds of Dispositions; Expenses. The Guarantor shall pay to NMT on
           ----------------------------------                                   
demand any and all expenses, including reasonable attorneys' fees and
disbursements, incurred or paid by NMT in protecting, preserving or enforcing
NMT's rights under or in respect of any of the Obligations or any of the
Collateral. After deducting all of said expenses, the residue of any proceeds of
collection or sale of the Obligations or Collateral shall, to the extent
actually received in cash, be applied to the payment of the Obligations in such
order or preference as NMT may determine, proper allowance and provision being
made for any Obligations not then due.  Upon the final payment and satisfaction
in full of all of the Obligations and after making any payments required by
Section 9-504(l)(c) of the Massachusetts Uniform Commercial Code, any excess
shall be returned to the Guarantor, and the Guarantor shall remain liable for
any deficiency in the payment of the Obligations.

     15.   Governing Law; Consent to Jurisdiction.  THIS AGREEMENT IS INTENDED
           --------------------------------------
TO TAKE EFFECT AS A SEALED INSTRUMENT AND SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS. The Guarantor
agrees that any suit for the enforcement of this Agreement may be brought in the
courts of The Commonwealth of Massachusetts or any federal court sitting therein
and consents to the non-exclusive jurisdiction of such court and to service of
process in any such suit being made upon the Guarantor by mail at the address
specified in of the Loan and Security Agreement. The Guarantor hereby waives any
objection that it may now or hereafter have to the venue of any such suit or any
such court or that such suit is brought in an inconvenient court.

     16.   Waiver of Jury Trial.  THE GUARANTOR WAIVES ITS RIGHT TO A JURY TRIAL
           --------------------                                                 
WITH RESPECT TO ANY ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION
WITH THIS AGREEMENT, ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THE PERFORMANCE OF
ANY SUCH RIGHTS OR OBLIGATIONS.  Except as prohibited by law, the Guarantor
waives any right which it may have to claim or recover in any litigation
referred to in the preceding sentence any special, exemplary, punitive or
consequential damages or any damages other than, or in addition to, actual
damages.  The Guarantor (i) certifies that neither NMT nor any representative,
agent or attorney of NMT has represented, expressly or otherwise, that NMT would
not, in the event of litigation, seek to enforce the foregoing waivers and (ii)
acknowledges that, in entering into the Loan and Security Agreement, NMT is
relying upon, among other things, the waivers and certifications contained in
this (S)19.

     17.   Miscellaneous. The headings of each section of this Agreement are for
           -------------
convenience only and shall not define or limit the provisions thereof. This
Agreement and all rights and obligations hereunder shall be binding upon the
Guarantor and its respective successors and assigns, and shall inure to the
benefit of NMT and its successors and assigns. If any term of this Agreement
shall be held to be invalid, illegal or unenforceable, the validity of all other
terms hereof shall in no way be affected thereby, and this Agreement shall be
construed and be enforceable as if such invalid, illegal or unenforceable term
had not been included herein. The Guarantor acknowledges receipt of a copy of
this Agreement.

                                   GUARANTEE


     This GUARANTEE is made as of May 29, 1997, by Robert Lee Thompson, an
individual residing at 8334 Dogwood Lane, Rogers, Arkansas 72756 (the
"Guarantor"), in favor of Nitinol Medical Technologies, Inc., a Delaware
corporation having a principal place of business at 27 Wormwood Street, Boston,
MA 02210 (the "Lender").  Capitalized terms not otherwise defined herein shall
have the meaning ascribed to them in that certain Loan and Security Agreement of
even date herewith by and between the Borrower (as defined below) and the Lender
(the "Loan Agreement").  In consideration of the Lender's entering into the Loan
Agreement with Image Technologies Corporation, a Delaware corporation having a
principal place of business at 27 Wormwood Street, Boston, MA 02210 (the
"Borrower"), and for other good and valuable consideration, the receipt of which
are hereby acknowledged, the Guarantor agrees as follows:

     1.  GUARANTEE OF PAYMENT AND PERFORMANCE.  The Guarantor hereby guarantees
to the Lender the full and punctual payment when due (whether at maturity, by
acceleration or otherwise), and the performance of all liabilities, agreements
and other obligations of the Borrower to the Lender, including, without
limitation, any and all obligations of the Borrower to the Lender arising out of
or related to the Loan Agreement, the Loan Documents or the Lender Guarantees,
whether direct or indirect, absolute or contingent, due or to become due,
secured or unsecured, now existing or hereafter arising or acquired (the
"Obligations").  This Guarantee is an absolute, unconditional and continuing
Guarantee of the full and punctual payment and performance of the Obligations
and not of their collectibility only and is in no way conditioned upon any
requirement that the Lender first attempt to collect any of the Obligations from
the Borrower or resort to any security or other means of obtaining their
payment.  Should the Borrower default in the payment or performance of any of
the Obligations, or should the Borrower or the Guarantor become insolvent or
make a composition, trust mortgage or general assignment for the benefit of
creditors, or if a proceeding under any federal or state bankruptcy,
reorganization, receivership, insolvency or other similar law affecting the
rights of creditors generally be filed or commenced by, against or in respect of
the Borrower or the Guarantor, the obligations of the Guarantor hereunder shall
become immediately due and payable to the Lender, without demand or notice of
any nature, all of which are expressly waived by the Guarantor.  Payments by the
Guarantor hereunder may be required by the Lender on any number of occasions.

     2.  GRANT OF SECURITY INTEREST.  To secure payment and performance of
Guarantor's Obligations hereunder, the Guarantor hereby grants to the Lender a
continuing lien on and security interest in the following properties, assets and
rights of the Guarantor, wherever located, whether now owned or hereafter
acquired or arising: all patents, patent applications, trademarks, trademark
applications (including, without limitation, those listed in Schedule I, hereto
                                                             ----------        
and made part hereof), license fees, income, royalties, trade names, copyrights,
copyright applications, rights to sue and recover for past infringement of
patents, present and future trademarks and copyrights, license fees, computer
programs, computer software, engineering drawings, service marks, customer
<PAGE>
 
lists, goodwill, and all licenses, permits, agreements of any kind or nature
pursuant to which the Guarantor possesses, uses or has authority to possess or
use property (whether tangible or intangible) of others or others possess, use
or have authority to possess or use property (whether tangible or intangible) of
the Guarantor, and all recorded data of any kind or nature, regardless of the
medium of recording including, without limitation, all software, writings,
plans, specifications and schematics, and all of Guarantor's rights to any of
the foregoing throughout the world (collectively, the "Pledged Collateral").  In
connection therewith, Guarantor agrees to execute and file in the United States
Patent and Trademark Office the Grant of Security Interest (Patents) in
substantially the form attached hereto as Exhibit A, and any and all additional
                                          ---------                            
documents, instruments and certificates as the Lender may reasonably require in
order to secure the Obligations.

     3.  GUARANTOR'S AGREEMENT TO PAY.  The Guarantor further agrees, as the
principal obligor and not as a guarantor only, to pay to the Lender, on demand,
all costs and expenses (including court costs, expenses and reasonable
attorney's fees) incurred or expended by the Lender in connection with the
Obligations, this Guarantee and the enforcement thereof, together with interest
on amounts recoverable under this Guarantee from the time such amounts become
due until payment, at the rate per annum equal to thirteen (13%) percent;
provided that if such interest exceeds the maximum amount permitted to be paid
under applicable law, then such interest shall be reduced to such maximum
permitted amount.

     4.  LIMITED GUARANTEE.  The Lender's sole recourse against the Guarantor
under this Guarantee shall be to the Pledged Collateral.

     5.  WAIVERS BY GUARANTOR; LENDER'S FREEDOM TO ACT.  The Guarantor agrees
that the Obligations will be paid and performed strictly in accordance with
their respective terms regardless of any law, regulation or order now or
hereafter in effect in any jurisdiction affecting any of such terms or the
rights of the Lender with respect thereto.  The Guarantor waives presentment,
demand, protest, notice of acceptance, notice of Obligations incurred and all
other notices of any kind, all defenses which may be available by virtue of any
valuation, stay, moratorium law or other similar law now or hereafter in effect,
any right to require the marshalling of assets of the Borrower, and all
suretyship defenses generally.  Without limiting the generality of the
foregoing, the Guarantor agrees to the provisions of any instrument evidencing,
securing or otherwise executed in connection with any Obligation and agrees that
the obligations of the Guarantor hereunder shall not be released or discharged,
in whole or in part, or otherwise affected by (i) the failure of the Lender to
assert any claim or demand or to enforce any right or remedy against the
Borrower; (ii) any extensions or renewals of any Obligation; (iii) any
rescissions, waivers, amendments or modifications of any of the terms or
provisions of any agreement evidencing, security or otherwise executed in
connection with any Obligation; (iv) the substitution or release of any entity
primarily or secondarily liable for any Obligation; (v) the adequacy of any
rights the Lender may have against any collateral or other means of obtaining
repayment of the Obligations; (vi) the impairment of any collateral securing the
Obligations, including without limitation the failure to perfect or preserve any
rights the Lender might have in such


                                      -2-
<PAGE>
 
collateral or the substitution, exchange, surrender, release, loss or
destruction of any such collateral; or (vii) any other act or omission which
might in any manner or to any extent vary the risk of the Guarantor or otherwise
operate as a release or discharge of the Guarantor, all of which may be done
without notice to the Guarantor.

     6.  APPLICATION OF PROCEEDS.  Any and all proceeds realized or obtained by
the Lender under this Guarantee shall be applied to the amounts outstanding
under the Loan Agreement or any other Loan Document, after payment of any and
all expenses, attorney's fees and other costs of collection hereunder in
accordance with the following:

         (a)  All such proceeds shall first be applied to the payment of any and
              all expenses, charges or other amounts which may be due and owing
              under the Loan Agreement or the Loan Documents;

         (b)  Any and all such proceeds remaining after application as provided
              in paragraph (a) above shall be applied to the payment of any
              principal, interest or charges outstanding under the Loan
              Agreement or the Loan Documents in accordance therewith, or if not
              provided, in the Lender's sole discretion; and

         (c)  Any surplus remaining after application as provided in paragraphs
              (a) and (b) above, shall be paid or returned to Guarantor, or its
              successors or assigns or to whomsoever may be lawfully entitled to
              receive the same.

     7.  UNENFORCEABILITY OF OBLIGATIONS AGAINST BORROWER.  If for any reason
the Borrower has no legal existence or is under no legal obligation to discharge
any of the Obligations, or if any of the Obligations have become irrecoverable
from the Borrower by operation of law or for any other reason, including,
without limitation, any release or discharge under any federal or state
bankruptcy, reorganization, receivership, insolvency or other similar law
affecting the rights of creditors generally, this Guarantee shall nevertheless
be binding on the Guarantor to the same extent as if the Guarantor at all times
had been the principal obligor on all such Obligations.  In the event that
acceleration of the time for payment of the Obligations is stayed upon the
insolvency, bankruptcy or reorganization of the Borrower, or for any other
reason, all such amounts otherwise subject to acceleration under the terms of
any agreement evidencing, securing or otherwise executed in connection with any
Obligation shall be immediately due and payable by the Guarantor.

     8.  SUBROGATION; SUBORDINATION.  The Guarantor shall not exercise any
rights and hereby waives any and all claims against the Borrower arising as a
result of payment by the Guarantor hereunder, by way of subrogation or
otherwise, and will not prove any claim in competition with the Lender or its
affiliates in respect of any payment hereunder in bankruptcy or insolvency
proceedings of any nature; the


                                      -3-
<PAGE>
 
Guarantor will not claim any set-off or counterclaim against the Borrower in
respect of any liability of the Guarantor to the Borrower; and the Guarantor
waives any benefit of and any right to participate in any collateral which may
be held by the Lender or any such affiliate.  The payment of any amounts due
with respect to any indebtedness of the Borrower now or hereafter held by the
Guarantor is hereby waived and postponed and subordinated to the prior payment
in full of the Obligations.  The Guarantor agrees that after the occurrence of
any default in the payment or performance of the Obligations by the Borrower,
the Guarantor will not demand, sue for or otherwise attempt to collect any such
indebtedness of the Borrower to the Guarantor until the Obligations shall have
been paid in full.  If, notwithstanding the foregoing sentence, the Guarantor
shall collect, enforce or receive any amounts in respect of such indebtedness,
such amounts shall be collected, enforced and received by the Guarantor as
trustee for the Lender and be paid over to the Lender on account of the
Obligations without affecting in any manner the liability of the Guarantor under
the other provisions of this Guarantee.

     9.  ENFORCEABILITY.  This Guarantee constitutes the legal, valid and
binding obligation of the Guarantor, enforceable against the Guarantor in
accordance with its terms, and will not contravene any existing law, rule or
regulation, or any agreement, order, judgment or decree to which Guarantor is a
party or by which Guarantor is bound.

     10.  FURTHER ASSURANCES.  The Guarantor agrees that it will promptly
provide to the Lender, copies of such information relating to the affairs of the
Guarantor as the Lender may reasonably request.  The Guarantor also agrees to do
all such things and execute all such documents, including financing statements,
as the Lender may consider necessary or desirable to give full effect to this
Guarantee and to perfect and preserve the rights and powers of the Lender
hereunder.

     11.  TERMINATION; REINSTATEMENT.  This Guarantee shall remain in full force
and effect until the payment is received in full of the Obligations.  This
Guarantee shall continue to be effective or be reinstated, if at any time any
payment made or value received with respect to an Obligation is rescinded or
must otherwise be returned by the Lender upon the insolvency, bankruptcy or
reorganization of the Borrower, or otherwise, all as though such payment had not
been made or value received.

     12.  SUCCESSORS AND ASSIGNS.  This Guarantee shall be binding upon the
Guarantor, its successors and assigns, and shall inure to the benefit of and be
enforceable by the Lender and its successors, transferees and assigns.  Without
limiting the generality of the foregoing sentence, the Lender may assign or
otherwise transfer any agreement or any note held by it evidencing, securing or
otherwise executed in connection with the Obligations, to any other person or
entity, and such other person or entity shall thereupon become vested, to the
extent set forth in the agreement evidencing such assignment or transfer, with
all the rights in respect thereof granted to the Lender herein.


                                      -4-
<PAGE>
 
     13.  AMENDMENTS AND WAIVERS.  No amendment or waiver of any provision of
this Guarantee nor consent to any departure by the Guarantor therefrom shall be
effective unless the same shall be in writing and signed by the Lender.  No
failure on the part of the Lender to exercise, and no delay in exercising, any
right hereunder shall operate as a waiver thereof; nor shall any single or
partial exercise of any right hereunder preclude any other or further exercise
thereof or the exercise of any other right.

     14.  NOTICES.  All notices and other communications called for hereunder
shall be made in writing and, unless otherwise specifically provided herein,
shall be deemed to have been duly made or given when delivered by hand or mailed
first class mail postage prepaid or, in the case of facsimile, when transmitted,
addressed as follows:  if to the Guarantor, at the address set forth above, and
if to the Lender, at the address set forth above, with a copy to Hale and Dorr
LLP, 60 State Street, Boston, Massachusetts 02109, Attn:  Steven D. Singer,
Esq., or at such address as either party may designate in writing.

     15.  GOVERNING LAW.  THIS GUARANTEE SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE LAWS (AND NOT THE LAW OF CONFLICTS) OF THE
COMMONWEALTH OF MASSACHUSETTS.

     16.  CONSENT TO JURISDICTION.  THE GUARANTOR HEREBY IRREVOCABLY SUBMITS TO
THE JURISDICTION OF THE COURTS OF THE COMMONWEALTH OF MASSACHUSETTS AND THE
UNITED STATES DISTRICT COURT OF MASSACHUSETTS FOR THE PURPOSE OF ANY SUIT,
ACTION OR OTHER PROCEEDING ARISING OUT OF OR RELATING TO THIS GUARANTEE AND THE
GUARANTOR HEREBY IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR
PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH COURT AND IRREVOCABLY WAIVES
ANY OBJECTION IT MAY NOW OR HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH SUIT,
ACTION OR PROCEEDING BROUGHT IN SUCH A COURT OR THAT SUCH COURT IS AN
INCONVENIENT FORUM.  NOTHING HEREIN SHALL LIMIT THE RIGHT OF THE LENDER TO BRING
PROCEEDINGS AGAINST THE GUARANTOR IN THE COURTS OF ANY OTHER JURISDICTION.  ANY
JUDICIAL PROCEEDING BY THE GUARANTOR AGAINST THE LENDER OR ANY AFFILIATE OF THE
LENDER INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER IN ANY WAY ARISING OUT OF,
RELATED TO, OR CONNECTED WITH THIS GUARANTEE SHALL BE BROUGHT ONLY IN A COURT IN
THE COMMONWEALTH OF MASSACHUSETTS.


                                      -5-
<PAGE>
 
     17.  WAIVER OF JURY TRIAL.  THE GUARANTOR HEREBY WAIVES TRIAL BY JURY IN
ANY JUDICIAL PROCEEDING INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER (WHETHER
SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO,
OR CONNECTED WITH THIS GUARANTEE OR THE RELATIONSHIP ESTABLISHED HEREUNDER.

Attn:  Theodore I. Pincus, Executive Vice President
       and Chief Financial Officer

     Re:  Loan and Security Agreement, dated as of May 29, 1997,
          between Image Technologies Corporation (the "Company")
          and Nitinol Medical Technologies, Inc. (the "Lender")
          ------------------------------------------------------


     We have acted as counsel to the Company, a Delaware corporation and Robert
Lee Thompson (the "Guarantor") in connection with the Loan and Security
Agreement by and between the Company and the Lender dated as of May 29, 1997 (as
the same may be amended from time to time, the "Loan and Security Agreement")
and the other Loan Documents (defined hereinafter).  Capitalized terms used
herein and not otherwise defined herein shall have the meaning ascribed to them
in the Loan and Security Agreement.

     For purposes of the opinions expressed below, we have examined:

     a.   the Loan and Security Agreement;

     b.   the Revolving Credit Note;

     c.   the Guarantee;

     d.   the Security Agreement;

     e.   the Grant of Security Interest (Patents) of the Guarantor;

     f.   the Grant of Security Interest (Trademarks) of the Company;
<PAGE>
 
     g.   such other documents, instruments and certificates delivered by the
          Company in connection with the transaction contemplated by the Loan
          and Security Agreement;

     h.   UCC-1 financing statements to be filed in the filing offices listed on
          Schedule I (the "Financing Statements");
                           --------------------   

     i.   the By-laws of the Company, as in effect on the date hereof, provided
          to us by the Company;

     j.   the corporate minute books of the Company, as provided to us by the
          Company;

     k.   certificates of legal existence and corporate good standing for the
          Company as identified on Schedule II;

     l.   certified copies of resolutions of the board of directors of the
          Company approving the transactions contemplated by the Loan Documents
          (defined hereinafter) and authorizing, among other things, the
          execution, delivery and performance by the Company of each of the Loan
          Documents (defined hereinafter) to which it is a party;

     m.   incumbency and signature certificates as to the officers of the
          Company; and

     n.   such other documents, instruments and certificates (including, but not
          limited to, certificates of public officials and officers of the
          Company) considered necessary for purposes of this opinion.

     The documents referred to in items (a) through (n) above are herein
referred to as the "Loan Documents."  In examining the documents described
above, we have assumed the genuineness of all signatures other than those of the
Company, the legal capacity of natural persons, the authenticity of all
documents submitted to us as originals and the conformity to the originals of
all documents submitted to us as copies.

     For purposes of this opinion, we have assumed that the Lender has the power
to execute, deliver and perform all agreements, documents and certificates
executed by the Lender; that the Lender has duly and validly executed and
delivered such agreements, documents and certificates; and that such agreements,
documents and certificates are legally valid and binding on and enforceable
against the Lender.


                                      -2-
<PAGE>
 
     On the basis of and subject to the foregoing, we are of the opinion that:

     1.   The Company is duly organized, validly existing and in good standing
          under the laws of the State of Delaware and is in good standing and
          authorized to do business in each other jurisdiction where such
          authorization is necessary to conduct the Company's business as
          contemplated by the Loan Documents to which it is a party.


     2.   The Company has full corporate power and authority to (i) own its
          real and personal property and to carry on its business as now
          conducted, (ii) enter into, execute and deliver each of the Loan
          Documents to which it is a party and (iii) carry out the terms of the
          Loan Documents to which it is a party all of which have been duly
          authorized by all proper and necessary corporate action.  In addition,
          the Company has full corporate power and authority to make the
          borrowings contemplated by the Loan Documents, to execute, deliver and
          carry out the terms of the Revolving Credit Note and to incur the
          obligations provided for therein, all of which have been duly
          authorized by all proper and necessary corporate action.


     3.   The execution and delivery by the Company and the Guarantor of the
          Loan Documents to which they are a party, do not, and the performance
          thereunder will not result in any violation of, be in conflict with,
          constitute a default under, give rise to any obligation to redeem
          securities under, or except for the security interests securing the
          Loan and Security Agreement and the other Loan Documents, result in
          the creation of a lien or encumbrance under, any term or provision of:
          (a) the charter or by-laws of the Company (b) any presently existing
          federal or state law, statute or governmental regulation, (c) any
          judgment, decree or order known to us in which the Company or the
          Guarantor, as the case may be, is named as a party, or (e) any
          material agreement to which the Company or the Guarantor, as the case
          may be, is a party.


     4.   Upon the Lender making the Revolving Credit Loan pursuant to the Loan
          and Security Agreement, the provisions of the Loan and Security
          Agreement, the Security Agreement, the Grant of Security Interest
          (Trademarks) executed by the Company and the Grant of Security
          Interest (Patents) executed by the Guarantor are sufficient to create
          in favor of the Lender a security interest in the Collateral and the
          Pledged Collateral (as defined in the Guaranty Agreement), of each of
          the respective parties thereto.  Upon the filing of the Financing
          Statements in the filing offices listed on Schedule I hereto, the
                                                     ----------            
          Lender will hold a first priority perfected security interest in the
          Collateral and the Pledged Collateral, as the case 


                                      -3-
<PAGE>
 
          may be, in which a security interest may be perfected by the filing of
          financing statements under Article 9 of the Uniform Commercial Code as
          in effect in the jurisdictions in which the filing offices are
          located. Upon the filing of the Grant of Security Interest (Patents)
          in the United States Patent and Trademark Office and the filing of the
          Grant of Security Interest (Trademarks) in the United States Patent
          and Trademark Office, the Lender will hold a first priority perfected
          security interest in the Pledged Collateral and the Collateral, as the
          case may be, in which a security interest may be perfected by such
          filings.

     5.   No consent, authorization or approval of, filing with, notice to, or
          exemption by, stockholders, any governmental body or any other person
          (except for those which have been obtained, made or given) (i) is
          required to authorize, or is required in connection with, the
          execution, delivery and performance of the Loan Documents or (ii) is
          required as a condition to the validity or enforceability of the Loan
          Documents.

     6.   There are no actions, suits or proceedings at law or in equity or by
          or before any governmental body (whether or not purportedly on behalf
          of the Company) pending or threatened against the Company, or any of
          its property or rights, which (i) if adversely determined, could
          reasonably be expected to have a material adverse effect on the
          Company, or (ii) call into question the validity of or the
          enforceability of any of the Loan Documents.

     7.   To our knowledge, neither the Company nor the Guarantor is in default
          under any mortgage, indenture, contract, agreement, judgment, decree
          or order to which it is a party or by which it is bound.  The
          execution or delivery of the Loan Documents and the carrying out of
          the terms of the Loan Documents will not constitute a default under,
          conflict with, require any consent under (other than consents which
          have been obtained) or result in the creation or imposition of, or
          obligation to create, any lien upon the property of the Company or the
          Guarantor pursuant to the terms of any such mortgage, indenture,
          contract, agreement, judgment, decree or order.

     This opinion is based upon currently existing statutes, rules, regulations
and judicial decisions, and we disclaim any obligation to advise you of any
change in any of these sources of law or other subsequent development which
might affect any matters or opinions set forth herein.
