4. REPRESENTATIONS AND WARRANTIES AND OTHER AGREEMENTS OF INVESTOR.

      4.1 REPRESENTATIONS AND WARRANTIES. Investor hereby represents and
warrants to the Company that:

            (a) ACCREDITED INVESTOR. Investor is an "accredited investor" as
defined in Rule 501(a) of Regulation D promulgated under the Securities Act of
1933, as amended (the "SECURITIES ACT") as noted below (INVESTOR TO INITIAL ALL
THAT APPLY):

            (i) ________ An individual whose individual net worth, or joint net
            worth with that person's spouse, at the time of the purchase exceeds
            $1,000,000;

            (ii) ________ An individual who had an individual income in excess
            of $200,000 in each of the two most recent years or joint income
            with that person's spouse in excess of $300,000 in each of those
            years and who reasonably expects to reach the same income level in
            the current year;

            (iii) _______ A corporation or partnership, not formed for the
            specific purpose of acquiring the Securities, with total assets in
            excess of $5 million; or

            (iv) _______ An entity in which all of the equity owners are
            accredited investors as set forth above.

As used in this paragraph, the term "net worth" means the excess of total assets
over total liabilities. For the purpose of determining a person's net worth, the
principal residence owned by an individual should be valued at fair market
value, including the cost of improvements, net of current encumbrances. As used
in this paragraph, "income" means actual economic income, which may differ from
adjusted gross income for income tax purposes. Accordingly, Investor should
consider whether it should add any or all of the following items to its adjusted
gross income for income tax purposes in order to reflect more accurately its
actual economic income: any amounts attributable to tax-exempt income received,
losses claimed as a limited partner in any limited partnership, deductions
claimed for depletion, contributions to an IRA or Keogh retirement plan, and
alimony payments.

            (b) AUTHORIZATION; RESIDENCY. Investor has full power and authority
to execute, deliver and perform the Transaction Documents and to acquire the
Shares. The Transaction Documents constitute the valid and legally binding
obligations of Investor, enforceable against Investor in accordance with their
respective terms, subject to applicable bankruptcy, insolvency, reorganization
and moratorium laws and other laws of general application affecting enforcement
of creditors' rights generally. Investor is a resident of the jurisdiction set
forth under its name on Investor's signature page hereto.

            (c) PURCHASE ENTIRELY FOR OWN ACCOUNT. The Shares to be purchased by
Investor and the Common Stock issuable upon conversion of the Shares
(collectively, the "SECURITIES") will be acquired for investment for Investor's
own account, not as a nominee or agent, and not with a view to the resale or
distribution of any part thereof, and Investor has no present intention of
selling, granting any participation in or otherwise distributing the same.
Investor does not have any contract, undertaking, agreement or arrangement with
any person or entity to sell, transfer or grant participation to such person or
to any third party with respect to any of the Securities.

                                       5
<PAGE>

            (d) RELIANCE UPON INVESTOR'S REPRESENTATIONS. Investor understands
that the Securities have not been registered under the Securities Act on the
ground that the sale provided for in this Agreement and the issuance of
securities hereunder is exempt from registration, and that the Company's
reliance on such exemption is predicated on Investor's representations set forth
herein. Investor realizes that the basis for the exemption may not be present
if, notwithstanding such representations, Investor has in mind merely acquiring
shares of the Securities for a fixed or determinable period in the future, or
for a market rise, or for sale if the market does not rise. Investor has no such
intention.

            (e) INVESTMENT EXPERIENCE. Investor is experienced in evaluating and
investing in private placement transactions of securities of companies in a
similar stage of development as the Company and acknowledges that Investor is
able to fend for itself, can bear the economic risk of Investor's investment and
has such knowledge and experience in financial and business matters that
Investor is capable of evaluating the merits and risks of the investment in the
Securities. If Investor is an entity not otherwise owned entirely by accredited
investors, Investor has not been organized for the purpose of acquiring the
Securities.

            (f) RESTRICTED SECURITIES. Investor understands that the Securities
may not be sold, transferred or otherwise disposed of without registration under
the Securities Act or an exemption therefrom, and that in the absence of an
effective registration statement covering the Securities or an available
exemption from registration under the Securities Act, the Securities must be
held indefinitely. In particular, Investor is aware that the Securities may not
be sold pursuant to Rule 144 promulgated under the Securities Act unless all of
the conditions of that Rule are met.

            (g) RECEIPT OF INFORMATION. Investor has received all the
information Investor considers necessary or appropriate for deciding whether to
purchase the Shares, including without limitation the Company's 1934 Act Reports
and the Company's Confidential Private Placement Memorandum dated November 2004
regarding the MEI Acquisition (the "PRIVATE PLACEMENT MEMORANDUM"). Investor has
had an opportunity to ask questions and receive answers from the Company
regarding the terms and conditions of this Offering and the business,
properties, prospects and financial condition of the Company and of MEI, and to
obtain additional information (to the extent the Company possessed such
information or could acquire it without unreasonable effort or expense)
necessary to verify the accuracy of any information furnished to Investor or to
which Investor had access.

            (h) ACKNOWLEDGEMENT OF INVESTMENT RISK. Investor understands that
much of the customer, market and competition information contained in
information supplied by the Company is based upon the Company's knowledge and
belief, and may be based on limited independent investigation. Investor further
understands that the future operating financial information provided by the
Company is for illustrative purposes only, and based upon certain hypothetical
assumptions and events over which the Company has only partial or no control. In


                                       6
<PAGE>

addition, the assumptions made by the Company and used in its forecasts are
inherently arbitrary. The selection of assumptions requires the exercise of
judgment and is subject to uncertainty due to the effects that operational,
economic, legislative or other changes may have on future events. The Company
considers it highly unlikely that each of these events will occur in the manner
and at the time anticipated in its financial forecasts. To the extent that the
occurrence or timing of actual events do not match the Company's assumptions,
the Company's actual operating and financial results will likely vary
substantially from its current financial projections. INVESTOR UNDERSTANDS THE
RISKS AND SPECIAL CONSIDERATIONS RELATING TO AN INVESTMENT IN THE COMPANY,
INCLUDING, WITHOUT LIMITATION, THOSE IDENTIFIED ON ATTACHED EXHIBIT B.

            (i) FINDER'S FEES. There are no claims for brokerage commissions or
finder's fees or similar compensation in connection with the transactions
contemplated by this Agreement based on any arrangement or agreement made by or
on behalf of Investor, and Investor agrees to indemnify and hold the Company and
the other investors in this Offering harmless against any damages incurred as a
result of any such claims.

      4.2 LEGENDS. Investor understands that certificates evidencing the Shares
may bear substantially the following legends:

            (a)   "The shares represented by this certificate have not been
                  registered under the Securities Act of 1933, as amended. The
                  shares may not be sold or offered for sale in the absence of
                  (a) an effective registration statement for the shares under
                  such Act, or (b) satisfactory assurances to the Company that
                  registration under such Act is not required with respect to
                  such sale or offer."

            (b)   Any legend required by the laws of any other applicable
                  jurisdiction.

5. CONDITIONS TO INVESTOR'S OBLIGATIONS AT CLOSING. The obligations of Investor
to purchase Shares at Closing are subject to the fulfillment on or before
Closing of each of the following conditions unless waived by such Investor:

      5.1 REPRESENTATIONS AND WARRANTIES. The representations and warranties of
the Company contained in Section 2 will be true and correct in all material

      5.5 MEI ACQUISITION. The Company will simultaneously be prepared to
complete the MEI Acquisition.

6. USE OF PROCEEDS. Proceeds from the sale of the Shares to all Investors in
this Offering will be used by the Company to pay a portion of the acquisition
price in the MEI Acquisition, to pay transaction costs associated with the MEI
Acquisition and for working capital. The Company anticipates that the sources
and uses of funds for the MEI Acquisition will be substantially as set forth in
attached Exhibit A.

7. MISCELLANEOUS.

      7.1 INCORPORATION BY REFERENCE. All exhibits appended to this Agreement
are incorporated by reference and made a part of this Agreement.

assigns of the parties hereto and transferees of the Shares.

      7.3 AMENDMENTS AND WAIVERS. Except as set forth in this Agreement, changes
in or additions to this Agreement may be made, or compliance with any term,
covenant, agreement, condition or provision set forth herein may be omitted or
waived (either generally or in a particular instance and either retroactively or
prospectively), or representatives to act on behalf of the holders of all of the
Shares may be designated, upon the written consent of the Company and the
holders of at least two-thirds of the outstanding Shares.

      7.4 GOVERNING LAW; JURISDICTION. This Agreement will be deemed a contract
made under the laws of the State of Oregon and, together with the rights and
obligations of the parties hereunder, will be construed under and governed by
the laws of such State, without giving effect to principles of conflicts of law.
The parties hereto irrevocably submit to the jurisdiction of any state or
federal court sitting in Multnomah County, Oregon, in any action or proceeding
brought to enforce, or otherwise arising out of or relating to, this Agreement,
and hereby waive any objection to venue in any such court and any claim that
such forum is an inconvenient forum.

      7.5 WAIVER OF JURY TRIAL; ATTORNEY FEES. Each party hereby irrevocably
waives any right it may have, and agrees not to request, a jury trial for the
adjudication of any dispute hereunder or in connection herewith or arising out
of this Agreement or any transaction contemplated hereby. In the event suit or
action is brought by any party under this Agreement to enforce any of its terms,
or in any appeal therefrom, it is agreed that the prevailing party or parties
will be entitled to reasonable attorneys fees to be fixed by the arbitrator,
trial court, and/or appellate court.

      7.6 INJUNCTIVE RELIEF. The parties agree that a breach or violation of
this Agreement will result in immediate and irreparable harm to the
non-breaching parties in an amount that will be impossible to ascertain at the
time of the breach or violation, and that the award of monetary damages will not
be adequate relief to the non-breaching parties. The non-breaching party will be
entitled to seek equitable or injunctive relief, in addition to other remedies
to which it may be entitled at law or equity. In any action for equitable
relief, the parties agree to waive any requirement for the posting of a bond or
security.

                  (b) Investor at its address set out on its signature page
hereto, or such other address as may be furnished in writing to the Company.

                  (c) Any other holder of Shares or the underlying Common Stock
at such address or facsimile number shown in the Company's records, or, until

Stock for which the Company has contact information in its records.

      7.8 ENTIRE AGREEMENT. This Agreement and the exhibits hereto constitute
the entire agreement among the Company and Investor with respect to the subject
matter hereof. This Agreement supersedes all prior agreements between the
parties with respect to the Shares purchased hereunder and the subject matter
hereof.

      7.9 SEVERABILITY. Each provision of this Agreement will be treated as a
separate and independent clause, and the unenforceability of any one clause will
in no way impair the enforceability of any of the other clauses. Moreover, if
one or more of the provisions contained in this Agreement will, for any reason,
be held to be excessively broad as to scope, activity, or subject so as to be
unenforceable at law, such provision or provisions will be construed by the
appropriate judicial body by limiting and reducing it or them, so as to be
enforceable to the maximum extent compatible with the applicable law as it will
then appear.

facsimile transmission of this signed Agreement will be legal and binding on all
parties hereto.

      7.11 FURTHER COOPERATION AND ASSURANCES. Each of the parties hereto will

                     RISK FACTORS AND SPECIAL CONSIDERATIONS

AN INVESTMENT IN THE COMPANY INVOLVES A HIGH DEGREE OF RISK. IN ADDITION TO THE
OTHER INFORMATION CONTAINED IN THIS AGREEMENT AND IN THE PRIVATE PLACEMENT
MEMORANDUM, YOU SHOULD CAREFULLY CONSIDER THE FOLLOWING RISKS BEFORE MAKING AN
INVESTMENT DECISION. YOU COULD LOSE ALL OR PART OF YOUR INVESTMENT DUE TO OUR
FINANCIAL CONDITION, THE PENDING MEI ACQUISITION AND ANY OF THESE RISKS. THE
RISKS AND UNCERTAINTIES DESCRIBED BELOW ARE NOT THE ONLY ONES WE FACE.
ADDITIONAL RISKS AND UNCERTAINTIES NOT PRESENTLY KNOWN TO US, OR THAT WE
CURRENTLY THINK ARE IMMATERIAL, MAY ALSO IMPAIR OUR BUSINESS OPERATIONS.

OUR ON-GOING BUSINESS PLAN IS BASED ON ASSUMPTIONS THAT COULD PROVE TO BE
INCORRECT, WHICH COULD MEAN THAT WE MAY BE UNABLE TO EXPAND AS PLANNED AND COULD
CAUSE US TO INVEST IN AREAS THAT DO NOT RESULT IN NEW SALES.

The key element of the Company's on-going business plan involves the expansion
of our ultrasound cable assembly capabilities and customer base. This effort
intends to capitalize on what we expect to be new growth in the medical
ultrasound equipment market. The success of our plan depends on numerous
assumptions that we cannot be sure are justified. If any of our key assumptions
are incorrect, we could be unable to expand our business as we currently
anticipate and we may make substantial investments in product development and/or
marketing efforts that do not result in new product sales. Our assumptions
include the following:

      o     demand for sophisticated "next generation" ultrasound imaging and
            diagnostic systems will continue to increase;

      o     our cable assembly capabilities that serve ultrasound system OEMs
            and our replacement ultrasound probes will efficiently address
            market needs as they develop;

      o     OEMs with whom we have or may develop relationships will be
            successful in developing their technologies and addressing their
            markets and will remain agreeable to outsource some or all of these
            cable assemblies; and

      o     other companies will not expand their cable assembly capabilities
            that offer technological or economic advantages over ours.

THE DEVELOPMENT OF ULTRASOUND IMAGING SYSTEMS BY OUR OEM CUSTOMERS IS USUALLY
SUBJECT TO REVIEW BY THE U.S. FOOD AND DRUG ADMINISTRATION AND OTHER REGULATORY
AGENCIES, WHICH MEANS THAT NEW CABLE ASSEMBLIES PROVIDED BY US THAT ARE DESIGNED
AS PART OF THESE SYSTEMS MAY NOT BE SOLD IN COMMERCIAL QUANTITIES FOR A LONG
TIME, IF EVER.

                                       14
<PAGE>

Our sales process involves designing our cable assemblies into both existing and
new OEM devices. The sale of any new system in commercial quantities is
generally preceded by a pre-production design phase in which we produce various
cable assembly prototypes based on a collaboration with the customer's
engineering and product design staff. The OEM's imaging systems are subject to
regulation and licensing, usually by the U.S. Food and Drug Administration
("FDA"), and sometimes by comparable foreign regulatory bodies, which increases
the cost and time required for the development, marketing and sale of these
systems. We expect that the sales cycle for most of our cable assemblies will
take 3-12 months to develop and validate. We are generally paid for prototypes
during the design phase but do not expect such payments to contribute
significantly to our profitability. If either our proposed cable assembly
solution or the overall imaging system is not approved or is not successfully
brought to market in a timely manner, the failure to do so will have a direct
and adverse impact on our future sales.

A LARGE PORTION OF OUR SALES IS CONCENTRATED WITH A FEW CUSTOMERS THAT COULD
MAKE FLUCTUATIONS IN REVENUE AND EARNINGS MORE SEVERE.

Sales to the Company's largest customer, GE Parallel Design, accounted for 69%
and 63% of our total ultrasound sales in 2003 and 2004, respectively. There are
a relatively limited number of OEMs that make ultrasound-imaging systems.
Although we provide cable assemblies and/or other services to industry-leading
OEMs and to several specialized competitors, the loss of a significant customer
could have a material adverse impact on us. While we expect the overall size of
the medical ultrasound market to expand, it remains possible that significant
penetration of these markets may depend on large volume sales to a limited
number of potential customers. Concentration in our customer base may make
fluctuations in revenue and earnings more severe and make business planning more
difficult.

LARGE OEM CUSTOMERS CAN CHANGE THEIR DEMAND ON SHORT NOTICE, FURTHER ADDING TO
THE UNPREDICTABILITY OF OUR QUARTERLY SALES AND EARNINGS.

Our quarterly results have in the past and may in the future vary significantly
due to the lack of dependable long-term demand forecasts from our larger OEM
customers. In addition to this risk, many of our OEM customers have the right to
change their demand schedule, either up or down, within a relatively short time
horizon. These changes may result in us incurring additional working capital
costs and causing increased manufacturing expenses due to these short-term
fluctuations. In particular, our quarterly operating results have in the past
fluctuated as a result of some of the larger OEM customers changing their orders
within a fiscal quarter. Our expense levels, to a large extent, are based on
shipment expectations in the quarter. If sales levels fall below these
expectations, operating results are likely to be adversely affected. Although we
have tried to lessen our dependency on a few large customers, this is the nature
of the OEM medical ultrasound industry that we serve and we can provide no
assurance that we will be able to materially alter this dependency in the
immediate future, if at all.

IN OUR HIGHLY COMPETITIVE MARKETS, MANY OF OUR POTENTIAL COMPETITORS HAVE
RESOURCES THAT WE LACK, WHICH COULD IMPAIR OUR RELATIONSHIPS WITH ACTUAL OR
POTENTIAL CUSTOMERS.

                                       15
<PAGE>

Our markets are highly competitive. This is particularly true in the area of
ultrasound cable assemblies sold to OEM customers. Competition is based on
technology, established relationships, quality of support, location of
facilities and price. Several of our competitors have a longer history of
operations and more established relationships with actual and potential
customers than we have. In addition, most of our OEM customers choose to
concentrate their cable assembly business with one or two suppliers and may have
certain geographic preferences. The combination of these factors may have a
direct and adverse impact on our ability to serve these customers in the future.
The Company's principal competitive advantages are: (a) low cost manufacturing
in Nogales, Mexico; (2) exceptional quality record; (3) highly responsive to
customers with quick turn capability; and (4) very competitive pricing. Despite
these advantages, many of our competitors and potential competitors have
technological and financial resources and established business relationships
that may afford them a competitive advantage.

INTELLECTUAL PROPERTY

Although we may apply for patents for some of our products, the patents may not
be granted or may not provide adequate protection of our intellectual property.
We intend to rely on copyrights, trademarks, trade secret laws and contractual
obligations with employees and third parties to protect our intellectual
property. Despite efforts to protect our intellectual property, unauthorized
parties may attempt to copy aspects of our products or obtain and use
information that we regard as proprietary. Our efforts to protect our
intellectual property from third-party discovery and infringement may be
insufficient and third parties may independently develop technologies similar to
ours, duplicate our products or design around any patents we may obtain. In
addition, third parties may assert that our products and technologies infringe
their intellectual property.

GROWTH MANAGEMENT

The rapid execution necessary for us to successfully implement our business plan
requires an effective planning and management process. We anticipate significant
growth and will be required to continually improve our financial and management
controls, reporting systems and procedures on a timely basis, and expand, train
and manage our personnel. There can be no assurance that our systems, procedures
or controls will be adequate to support our operations or that our management
will be able to achieve the rapid execution necessary to successfully implement
our business plan.

DEPENDENCE ON KEY PERSONNEL

Our success depends on our ability to identify, attract and retain highly
qualified personnel and the failure to do so could have a material adverse
effect on us.

FUTURE CAPITAL NEEDS AND THE UNCERTAINTY OF ADDITIONAL FINANCING

In addition to the funding provided by the proceeds of the sale of Series B
Preferred Stock under this Offering, to complete and implement our business plan
we may need to raise significant additional funds. There can be no assurance
that additional financing, if needed, will be available on terms favorable to
us, or at all.

OFFERING PRICE AND CONVERSION RATIO

The price per share and conversion ration of the Series B Preferred Stock was
set by us. Although set in good faith, the price and/or conversion ratio may not
bear any direct relationship to the assets, results of operations or other
objective criteria of value applicable to us.

ILLIQUID INVESTMENT

The Securities have not been registered under the Securities Act and are being
offered in reliance upon an exemption from registration under the Securities Act
and applicable state securities laws. The Securities can only be transferred or
resold in a transaction under or exempt from the Securities Act and applicable
state securities laws. There is no public market for the offered Series B
Preferred Stock, and there is no guarantee that any public market for these
securities will develop. For these reasons Investors may not be able to
liquidate their investment in the Company in the event of an emergency or for
any other reason. Consequently, the purchase of Series B Preferred Stock, and
the acquisition of Common Stock upon the conversion of Series B Preferred Stock,
should be considered only as a long-term investment.
