Preferred Stock ("Series C Stock") from the prior owners and on January 30, 1997
TFX acquired an additional 150,000 shares of Common Stock from the Company
giving it approximately 48% of the Company's outstanding voting securities.

Sterilization Services to Health Care Providers:

      As of April 1, 1998, the Company had entered into 71 contracts with
revenues from these contracts of approximately $20,227,000 through 2003 with
hospitals in its area to sterilize their surgical instruments, utensils and
other items requiring sterilization ("Sterilizable Items") and to provide the
hospitals with MSI's standard containerized reprocessable instrument sets (the
"Instrument Sets"). The Company is also negotiating contracts or purchase
orders, with additional hospitals although there is no assurance that these
contracts will be executed.

Sterilization of Disposable Medical Products and Processing of
Industrial Products Including PTFE

      During 1997 MSI provided contract sterilization of disposable medical
products for approximately 39 manufacturers located within an approximately 300
mile radius of the Company's facility in Syosset.

      In addition, during 1997 the Company also performed radiation processing
for 15 manufacturers of plastic products and irradiated PTFE, also known by the
term "Teflon", a registered trademark of E. I. Dupont de Nemours & Co., for
Precision Micron Powders, Inc. ("Precision") and for Shamrock pursuant to a Toll
Processing Agreement, which was extended to December 31, 1997. Revenues from
such processing services were approximately $3,040,000 in 1997.

      Because of the closing of its sale of the accelerator, scheduled for April
30, 1998 and its agreement with E-BEAM, it has not provided such sterilization
services in 1998. Furthermore, pursuant to the Toll Processing Agreement, the
Company is not permitted to process PTFE for any other party after December 31,
1997.

Risk Factors

      The purchase of the securities involves a high degree of risk. Risk
factors to be considered include the Company's history of losses since
inception; the Company's lack of working capital; the competition which could
affect growth; the Company's dependence on key personnel; the Company's
dependence in 1998 and in the future on revenues from sterilization services of
Sterilizable Items; the termination of its processing of medical disposables,


                                       9
<PAGE>

industrial products and PTFE (in 1997 such processing accounted for
approximately 41.2% of the Company's revenues); the effect of government
regulations; the fact that dividends are not likely; the control by insiders and
the provisions for indemnification of Directors; and the fact that all the
Company's principal shareholders are registering all shares owned by such
persons for resale.

Use of Proceeds

      The Selling Shareholders and any warrant holders or option holders who
receive Common Stock on the exercise of options or warrants and the holders of
Series B and C Stock who receive shares of stock on conversion of Preferred
Stock will receive all of the proceeds of the sale of shares of Common Stock in
this offering. and the Company will receive no part thereof. As previously set
forth, this registration statement relates only to the sale of shares held or
acquired by the Selling Shareholders. The holders of the Preferred Stock may
convert the Preferred Stock into Common Stock, and the Company will not receive
any funds on such conversion.

Market for Registrant's Common Equity

      The Company's Common Stock is sold in the over-the-counter market and is
quoted on the NASDAQ Bulletin Board. The average of the bid and asked prices on
April 15, 1998 was $1.13.

      MSI was incorporated on May 27, 1982. The Company's executive offices are
located at 225 Underhill Boulevard, Syosset, New York 11791 and its telephone
number is (516) 496-8822.


                                       10

                                  RISK FACTORS

THE SECURITIES OFFERED HEREBY INVOLVE A HIGH DEGREE OF RISK.
THE COMPANY HAS INCURRED SUBSTANTIAL LOSSES SINCE ITS
FORMATION.  ACCORDINGLY, THE SHARES SHOULD NOT BE PURCHASED BY ANYONE
WHO CANNOT AFFORD THE LOSS OF HIS OR HER ENTIRE INVESTMENT.

      1. History of Losses, Adverse Operating History. The Company has operated
at a loss or very small profit for each year. In 1996, the net loss was
approximately $995,000 and after deduction of undeclared dividends on preferred
stock was approximately $1,119,000. For the year ended December 31, 1997, the
Company's net income was approximately $613,000, and the net income after
deducting the undeclared dividends on preferred stock was approximately
$504,000. From inception through December 31, 1997 the Company had an
accumulated deficit of approximately $7,961,000. During this period the Company
financed its operations through receipts from operations. the sale of stock and
borrowing money from individuals, corporations and lending institutions.

      2. Lack of Working Capital; Need for Additional Financing. Since the date
of incorporation, May 27, 1982, the Company was engaged in raising capital,
leasing and equipping a sterilization facility and establishing a market
program. It reported as a development stage enterprise through December 31,
1984. Subsequent thereto it has engaged in service to hospitals, contract
radiation service and the processing of PTFE. As previously stated, the contract
radiation service and processing of PTFE terminated at the end of 1997.

      As of December 31, 1997, the Company had working capital of approximately
$1,530,000 as compared to working capital of approximately $292,000 as of
December 31, 1996. The increase in working capital was primarily the result of
the classification of $1,250,000 as current assets held for sale in connection
with the sale of the accelerator.

      The principal of its loan with its former principal bank is $451,836 as of
December 31, 1997 with the principal being amortized on a monthly basis at the
rate of $12,500 per month with a balloon payment due May, 1998. The principal of
the loan is to be paid out of the proceeds from the sale of the Accelerator to
Shamrock scheduled for April 30, 1998.

      The Company's line of credit arrangement with Rosenthal & Rosenthal, Inc.
("Rosenthal") calls for a revolving collateralized line of credit of up to
$2,000,000 with an expiration date of January 31, 2000. The line of credit is
collateralized by basically all of the assets of the Company. The Company can
borrow up to 85% of its eligible accounts receivable. The interest rate on the
facility is prime plus 2%.

      In January, 1997, the Company entered into a loan agreement with TFX. The
principal amount of the loan is now $250,000 and bears interest at the rate of
prime plus 1%. The note is due and payable on May 8, 1998.


                                       11
<PAGE>

      On April 21, 1997, the Company entered into an operating lease agreement
with North Fork Bank in the amount of $1,500,000, pursuant to which the Bank
will purchase the Company's instrument needs and lease them to the Company. The
agreement has an interest rate of prime plus 1/2%. The lease agreement is
guaranteed by Teleflex. Furthermore, on April 9, 1997, the Company received
$150,000 from E-BEAM on execution of the Joint Marketing Agreement and no later
than April 30, 1998, the Company will receive approximately $1,250,000 from the
sale of the accelerator to Shamrock.

      As of May 16, 1997, the Company entered into a joint venture agreement
with TFX to incorporate SSI which would provide offsite and on-site processing
and sterilization services for health care providers in all of North America
except the Northeast corridor. In this joint venture MSI has 37.5% of the Common
Stock of SSI and TFX has 62.5% of such Common Stock. In addition, TFX acquired
100 shares of Preferred Stock for the sum of $5,000,000.

      Management believes that with the extension of the Rosenthal agreement,
the operating lease agreement with North Fork Bank, the loan from TFX, the
moneys received from E-BEAM and to be received from Shamrock, and the SSI joint
venture the Company will have adequate working capital for the foreseeable
future. However, the Company may require additional working capital in the
future and there can be no assurance that such additional working capital will
be on acceptable terms, if at all.

      3. Competition. The Company's principal competition with respect to its
sterilization services for healthcare providers comes from the in-house
sterilization facilities of hospitals and ambulatory surgi-centers. Most
hospitals have an in-house sterilization capability and many have invested
significant capital in their sterilization facilities. Also, the in-house
sterilization facility staff may be committed to maintaining the facility and
its current staffing levels. As a result, healthcare providers may be reluctant
to shift their sterilization activities from in-house to an offsite contractor.
Furthermore, some hospitals have union agreements that preclude or mitigate a
hospital's ability to outsource.

      MSI has no competitor operating in an off-site environment which can
replicate MSI's sterilization services program though variations of the MSI
model potentially exist and/or have been announced in traditional hospital
purchasing news. Sterile Recoveries, Inc., Sterilization Management Group and
Angelica Corp. now compete with the Company in processing gowns, linens and
basins but their operating facilities are all outside the Northeast Corridor.
Substantial know-how and capital intensive barriers could limit competitive
interest. Furthermore, the Company's proprietary hospital tracking software
system gives it a competitive advantage.

      The number of hospitals the Company has been servicing has not changed
significantly in 1995 and 1996, averaging about 27 hospitals, but as of March
20, 1998, the number of hospitals under contract was 43. The aggregate annual
revenue from the hospital contracts has increased from approximately $4,726,000
in 1996 to approximately $5,819,000 in 1997. Prior to 1997, the Company's
revenues from its hospital sterilization services were at a 


                                       12
<PAGE>

volume below that which yielded a profit to the Company. In 1997 there was a
profit of approximately $305,000 from its hospital sterilization services.

      Several small and large companies are specializing in on-site instrument
processing, consulting and management services, providing hospitals and hospital
networks a competitive choice between MSI's offsite instrument processing and
sterilization services. A wholly owned subsidiary of Teleflex, Endoscopy
Specialists, Incorporated ("ESI"), specializes in on-site instrument processing.
However, as previously stated MSI and TFX jointly formed SSI to provide
instrument processing in North America and SSI, MSI and ESI have joined to
provide a total instrument management solution for individual hospitals and
hospital networks throughout North America..

      4. Dependence on Key Personnel. Dr. Kennard H. Morganstern, the founder
and Chairman of the Board of the Company, has entered into a transition
agreement with the Company, providing that for a period of three years
commencing September 8, 1996 Dr. Morganstern will serve as Chairman of the Board
of the Company and make available at least 50% of his time for consulting
purposes at an annual salary of $75,000. D. Michael Deignan was elected
President on September 8, 1995 and became Chief Executive Officer on January 3,
1996.

      5. Dependence on Relatively Few Customers. As previously stated, the
Company has contracted to sell its accelerator to Shamrock no later than April
30, 1998. The contract to irradiate PTFE terminated on December 31, 1997. In
addition, the Company has entered into a Joint Marketing Agreement with E-BEAM
which provides for the Company to transfer its customer lists to E-BEAM.
Accordingly, the processing of PTFE and medical disposables and products has
terminated.

      In its sterilization services for health care providers, the Company has
71 contracts with 43 hospitals and is not dependent on a relatively few
customers.

      6. Government Regulations. The Company has complied with the requirements
of and obtained a license from the New York State Department of Labor, Division
of Safety and Health Radiological Health Unit for its electron beam radiation
sterilization and processing facility. This license is in force.

      The Company also obtained a license from the New York State Department of
Environmental Conservation operating through the Nassau County Department of
Health to operate its radiation sterilization and processing facility. This
license is currently in force and will remain in force until April 30, 1998
unless extended.

      The Company is also registered with the Department of Health and Human
Services, Public Health Service of the Food and Drug Administration ("FDA"), and
conforms to the FDA compliance program with regard to the industrial
sterilization or medical devices. The Company complies with the FDA compliance
program, even though for these purposes, a hospital (the Company, by extension)
is not subject to the FDA regulations.


                                       13
<PAGE>

      The Company also complies with the regulations of the New York State
Department of Health, acting through the Nassau County Department of Health,
with regard to the disposition of effluents. The Company complies with
regulations of the New York State Department of Environmental Conservation
concerning the handling and disposal of regulated medical waste.

      Finally, the Company also complies with the requirements of the
Occupational Safety and Health Administration ("OSHA").

      7. Dividends Not Likely. For the foreseeable future it is anticipated that
any earnings which may be generated from operations of the Company will be used
to finance the growth of the Company and that cash dividends will not be paid to
shareholders. In addition, the terms of certain of the Company's loan
agreements, the Financing Agreement with Rosenthal & Rosenthal, Inc. and the
Series B and C Stock prohibit the payment of dividends on Common Stock.

      8. Dilution and Market Price. As of April 15, 1998, the Company had
3,170,496 Shares outstanding. The tangible book value (deficit) of the shares as
of said date is ($.06). 805,000 Shares to be received by the Selling
Shareholders upon the exercise of options granted under the Company's 1994 Stock
Option Plan, 355,000 Shares to be received by the Selling Shareholders upon the
exercise of warrants, 2,633,125 Shares issuable to the Selling Shareholders upon
conversion of Series B and C Stock, and 556,667 Shares presently held by Selling
Shareholders and acquired either by purchase in private placements, exercise of
options and warrants or conversion of Preferred Stock are registered hereunder
for the future sale of said shares by the Selling Shareholders and are the
subject of this prospectus. Although the Company cannot predict that any warrant
holder or option holder will exercise their warrants or options, the issuance of
such Shares upon exercise of the warrants, options and the conversion of the
Preferred Stock will constitute an immediate substantial dilution in earnings
per share but an increase in book value per share to existing shareholders. The
Selling Shareholders may realize a dilution of their investment because the
exercise price of their options or warrants may be higher than the book value
per share of the Common Stock after the exercise. Furthermore, any sales of
substantial amounts of the Company's stock in the open market by the Selling
Shareholders could have a significantly adverse effect on the market price of
such stock. The Company will not receive the proceeds of sales of stock by the
Selling Shareholders.

      9. Control by Insiders. As of April 15, 1998, all officers and directors
including designees of TFX as a group held approximately 66% of the Company's
outstanding stock. Dr. Cartinhour bought 300,000 shares of the Company's Common
Stock in a private placement on September 3, 1987. Dr. Cartinhour is not deemed
to be an insider.


                                       14
<PAGE>

      On January 8, 1997, approximately 45% of the voting shares of the
Company's stock was acquired by TFX. TFX purchased the Series B Stock and Series
C Stock from the previous owners of such stock. In connection with this
transaction and after the resignation of three of the incumbent Directors, three
nominees of TFX, were elected to the Company's Board of Directors. In January,
1997, the Company issued 150,000 shares of its common stock to TFX to pay
$300,000 of accounts payable due to Pilling Weck, a subsidiary of Teleflex. This
increased TFX's interest in the outstanding voting securities to approximately
48%.

      For the purposes of the foregoing calculations of percentage ownership of
stock, the securities which are not outstanding but could be outstanding on the
exercise of stock options and warrants or conversion of the Preferred Stock have
been deemed outstanding. It is clear that after the exercise of options and
warrants and conversion of Convertible Preferred Stock, the Company will be
controlled by insiders.

      10. Indemnification of Directors. Insofar as indemnification for
liabilities arising under the Securities Act of 1933 may be permitted to
directors, officers and controlling persons of the registrant pursuant to the
Company's ByLaws or New York Law, or otherwise, the registrant has been advised
that, in the opinion of the Securities and Exchange Commission, such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless, in the opinion of its counsel, the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

      11. Preferred Stock. In 1994, the Company restructured the 750,000 shares
of Series A Convertible Preferred Stock into what now amounts to 687,500 shares
of Series B Stock and 1,945,625 shares of Series C Stock. The Series C Stock is
automatically converted into Common Stock on December 30, 2004 and there are no
dividends payable or accrued on such stock. Furthermore, the Series C Stock will
be automatically converted into Common Stock if the market price of the
Company's Common Stock as quoted on NASDAQ, attains and maintains for 90 days a
price of $3.00 per share during the five years ending October 31, 1999. The
Series B Stock will be automatically converted into Common Stock if the market
price of the Company's Common Stock attains and maintains for 90 days a price of
$6.00 per share during the five years ending October 31, 1999. The Series B
Stock matures December 30, 1999 and dividends accrue at the rate of 8% per year.
At that time the Company will have to pay to the Series B Shareholders the sum
of $1,373,000 plus an amount equal to all unpaid accrued dividends unless the
Series B Stock has been automatically converted as set forth above. In the event
the Series B Stock has not been converted prior to December 30, 1999, the
Company will either have to negotiate an extension of time to pay such sum or
obtain 


                                       15
<PAGE>

other financing to pay it. There is no assurance at this time that the Company
will be able to obtain sufficient funds to pay the Series B shareholders or
obtain an extension of time.

      12. The Lease. On November 20, 1995, the landlord and the Company entered
into a new lease covering the period from March 1, 1996 to February 28, 2001 at
annual rates of $456,000 for the first three years and $504,000 for the next two
years.

      13. Shares Registered by Selling Shareholders. All of the Company's
principal shareholders, as well as its key employees, are registering for resale
all shares received or to be received by such persons on exercise of options,
warrants or preferred stock or on private placements for resale. These persons
are registering 556,667 shares of Common Stock, 2,633,125 shares of Common Stock
on conversion of the Series B and Series C Stock, and options and warrants
exercisable within 60 days to acquire 1,160,000 shares in the aggregate. Sales
of substantial amounts of Common Stock in the open market following this
offering could adversely affect the market price of the Common Stock.

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

Overview

      The Company reported net income of approximately $613,000 in the year
ended December 31, 1997 compared to a net loss of approximately $995,000 in the
year ended December 31, 1996. The increase in net income was mainly the result
of a record influx of newly contracted hospital business during 1997, improved
control of operating and selling, general and administrative expenses, and the
absence of prior year bad debt losses and one-time costs related to legal
expenses, as well as, the one-time charge of $103,000 to reflect the reduction
of the value of the E-Beam Accelerator that was contracted to be sold to
Shamrock in 1997. The Company was also able to reduce its selling, general and
administrative costs related to certain national marketing expenses, by forming
SSI, the new joint venture company with TFX. TFX acquired all of the Company's
outstanding Convertible Preferred Stock in 1997, and now holds approximately 48%
of voting stock in the Company. Another Teleflex subsidiary, ESI, which owns and
manages endoscopic and specialized instrumentation and provides on-site
processing services, will also join with the Company and SSI to provide a total
instrument management solution for individual hospitals and hospital networks
throughout North America.

      Under the agreement with TFX, the Company will remain as an independent
public entity, whose territory will encompass the Northeast Corridor. In this
territory, which accounts for approximately 20 percent of the surgical
procedures in the United States, the Company will continue to provide its
instrument management and sterilization services. SSI will be responsible for
marketing and delivering these same services to the remainder of the United
States and Canada.

      Terms of the agreement provide that TFX will own 62.5 percent of the
common shares of SSI and the Company will own the remaining 37.5 percent. The
Company will contribute personnel and know-how, including its proprietary
multi-hospital tracking system and a developing customer list in select highly
populated urban centers. TFX will provide the initial operating and project
capital required to fund expansion into markets as SSI contracts are executed.
ESI will also contribute its know-how.

      For the fiscal year ended December 31, 1997, the Company's sterilization
services for healthcare providers, contract sterilization of disposable medical
products and radiation processing of industrial products businesses accounted
for approximately 58.8%, 10.4% and 30.8%, respectively, of the Company's
revenues, as compared with 55.1%, 11.0% and 33.9%, respectively, for the fiscal
year ended December 31, 1996. The Company's Board of Directors has determined
that it is in the best interests of the Company's shareholders that the Company
focus on its core Instrument Set sterilization processing business. Accordingly,
it has contracted to sell its Accelerator system to Shamrock and has entered
into a joint marketing agreement with E-BEAM. Under the Agreement with Shamrock
the Company will receive approximately $1,250,000 for the Accelerator and
related equipment with a Closing 


                                       17
<PAGE>

Date of no later than April 30, 1998 at which time title to the beam would be
transferred to Shamrock. Shamrock has posted a $500,000 standby letter of credit
in escrow in consideration therefor.

      In January, 1997, the Company entered into a loan agreement with TFX. The
principal amount of the loan is $500,000 and bears interest at the rate of prime
plus 1%. The balance of the loan at December 31, 1997, was $400,000. Monthly
installment payments in increments of $50,000 are due the beginning of 1998,
with the entire balance of principal and interest unpaid due and payable on May
8, 1998.

      In January, 1997, the Company issued 150,000 shares of its common stock to
TFX in settlement of $300,000 of accounts payable due to Pilling Weck, a
subsidiary of Teleflex.

      In April, 1997, the Company entered into a joint marketing agreement and
an agreement to sell its contract sterilization services to E-BEAM effective
December 31, 1997. Under the terms of the agreement, the Company will receive a
maximum purchase price of $350,000 for the business based on a schedule of
commissions earned at up to 15 percent of related revenues from January 1, 1998
to December 31, 2000. Upon execution of the agreement, the Company received a
nonrefundable deposit of $150,000.

      In April, 1997, the Company entered into a master lease agreement with
North Fork Bank in the amount of $1,500,000. The lease provides for and was
drawn down to purchase instruments for inventory and was classified as a capital
lease. The agreement has an interest rate of prime plus 1/2 percent which is set
at each draw down. The lease agreement is guaranteed by Teleflex.

      In October, 1997, the Company extended and modified its financing
agreement with its commercial lender. The agreement was extended to January 31,
2000, and the advance rate on the Company's eligible Accounts Receivable was
increased to 85% from the existing 75%. The total cost of funds was also reduced
through a reduction in the interest rate on the facility from the prime rate
plus 3.5% to prime plus 2%, and a reduction in the facility fee from 1% to 1/2%
of the loan balance per annum. See Note 6 to the Financial Statements.

Results of Operations

1997 Compared with 1996

Revenues

      Revenues for the year ended December 31, 1997 increased approximately
14.7% to $9,890,000 from approximately $8,626,000 for the year ended December
31, 1996. The increase in revenues was attributable to an approximate $1,081,000
or 22.8% increase in total revenues related to the Company's sterilization
services to healthcare providers, an approximate $110,000 or 3.7% increase in
total revenues related to the Company's radiation processing of industrial
products services and an approximate $73,000 or 7.6% increase in 


                                       18
<PAGE>

total revenues related to the Company's contract sterilization services. The
increase in total revenues related to the Company's sterilization services to
healthcare providers was attributable to market penetration of new customers and
expanded services to the Company's existing customer base. During 1997, the
Company signed several new multi-year contracts with major healthcare providers
in the region. The increase in radiation revenues was primarily attributable to
the acceleration of Teflon processing related to the impending termination of
these services. The increase in contract revenues, in turn, was mainly
attributed to renegotiated rates with certain key customers to more accurately
reflect the service provided by the Company.

Other Income

      In April 1997, the Company received $150,000 in connection with the sale
of its contract sterilization services to E-BEAM, which is nonrefundable. This
receipt has been reported as other income.

Gross Profit

      Gross profit (revenues minus operating expenses) increased approximately
$1,017,000 or 35.2% from approximately $2,887,000 in the year ended December 31,
1996 to approximately $3,904,000 in the year ended December 31, 1997. Gross
profit as a percentage of revenues increased approximately 6.0% from 33.5% in
the year ended December 31, 1996 to 39.5% in the year ended December 31, 1997.
The increase in the Company's gross profit was attributable to improved
production efficiencies in the Company's facility and the flow on benefits from
increased sales volumes. The major components of these efficiencies were a
reduction in labor as a percentage of revenues and a reduction in supplies used
in production offset by other increases related to new volume.

Distribution Costs

      Distribution costs increased approximately $72,000 or 15.2% from
approximately $471,000 in the year ended December 31, 1996 to approximately
$543,000 in the year ended December 31, 1997. As a percentage of revenues,
distribution costs remained relatively the same over the prior year at 5.5%. The
increase is primarily the result of increased sales volume.

Selling, General and Administrative Expenses

      Selling, general and administrative expenses decreased by approximately
$101,000 from approximately $2,442,000 in the year ended December 31, 1996 to
approximately $2,341,000 in the year ended December 31, 1997. As a percentage of
revenues, selling, general and administrative expenses decreased from 28.3% in
the year ended December 31, 1996 to 23.7% in the year ended December 31, 1997.
The decrease is attributed to the Company's continued strategy to reduce
discretionary costs, in addition to certain national 


                                       19

marketing expenses being borne by SSI whereas last year they were borne by the
Company, and reduced legal expenses.

Bad Debt Expense

      Bad debt expense decreased by approximately $499,000 from approximately
$560,000 in the year ended December 31, 1996 to approximately $61,000 in the
year ended December 31, 1997. The decrease is attributed to write-offs and
adjustments made in 1996 related to a receivable from a customer in bankruptcy
and the settlement of amounts in dispute. The Company has determined that its
allowance for doubtful accounts is sufficient to cover the receivables from its
hospital operations.

Write Down of Assets

       The decrease of approximately $103,000 is related to the charge taken in
1996 to reflect the reduction in the value of assets associated with the sale of
the electron beam Accelerator. In March 1997, the Company entered into a sales
agreement to sell the Accelerator to Shamrock.

Interest Expense

      Interest expense increased by approximately $179,000 from approximately
$307,000 for the year ended December 31, 1996 to approximately $486,000 for the
year ended December 31, 1997. The increase is directly attributed to the
increased interest charges incurred in financing the purchase of surgical
instruments and other equipment and the additional borrowing of $500,000 from
TFX.

Net Income

      Net income for the year ended December 31, 1997 was approximately
$613,000, an increase of 161.6% from a net loss of approximately ($995,000) in
the year ended December 31, 1996.

Net Income (Loss) Applicable to Common Shareholders

      Diluted earnings per share for the year ended December 31, 1997 were
approximately $0.09, a 124.3% increase from the net loss per share of
approximately ($0.37) for the year ended December 31, 1996. Basic earnings per
share for the year ended December 31, 1997 were $0.16, an increase of 143.2%
from ($0.37) in basic earnings per share for the year ended December 31, 1996.
Excluding the effect of preferred dividends, earnings per share for the year
ended December 31, 1997 were $0.11, an increase of 133.3% from ($0.33) in
earnings per share before the effect of preferred dividends for the year ended
December 31, 1996.

Results of Operations

1996 Compared with 1995

Revenues

      Revenues for the year ended December 31, 1996 decreased approximately 1.7%
to approximately $8,626,000 from approximately $8,772,000 for the year ended
December 31, 1995. The decrease in revenues was attributable to an approximate
$18,000 increase in total revenues related to the Company's sterilization
services to healthcare providers and an approximate $225,000 or 8.3% increase in
total revenues related to the Company's radiation processing of industrial
products services, offset by an approximate $389,000 or 28.9% decrease in total
revenues related to the Company's contract sterilization services. The increase
in radiation processing revenues was primarily attributable to increased
business under the Company's toll processing agreement with Shamrock. The
decrease in the contract sterilization business was due primarily to the loss of
the Company's largest customer which moved its business out of the Company's
area of operation.

Gross Profit

      Gross profit (revenues minus operating expenses) increased approximately
$161,000 or 5.9% from approximately $2,726,000 in the year ended December 31,
1995 to approximately $2,887,000 in the year ended December 31, 1996. Gross
profit as a percentage of revenues increased approximately 2.4% from 31.1% in
the year ended December 31, 1995 to 33.5% in the year ended December 31, 1996.
The increase in the Company's gross profit was attributable to improved
production efficiencies in the Company's facility. The major components of these
efficiencies were a reduction in labor as a percentage of revenues and a
reduction in supplies used in production.

Distribution Costs

      Distribution costs increased approximately $94,000 or 25.0% from
approximately $377,000 in the year ended December 31, 1995 to approximately
$471,000 in the year ended December 31, 1996. The increase is primarily the
result of higher wages for drivers.

Selling, General and Administrative Expenses

      Selling, general and administrative expenses increased by approximately
$654,000 from approximately $1,788,000 in the year ended December 31, 1995 to
approximately $2,442,000 in the year ended December 31, 1996. As a percentage of
revenues, selling, general and administrative expenses increased from 20.4% in
the year ended December 31, 1995 to 28.3% in the year ended December 31, 1996.
The major portion of the increase was the result of the Company making a
significant investment in its national sales and marketing areas. The Company
strengthened these areas as it prepared to expand from a Regional Company to a
National Company. In addition the Company had above normal historical 


                                       21
<PAGE>

levels of legal expenses from its new legal counsel and additional one time
termination expenses incurred as result of the elimination of an Officer's
position. Also, the Company added a full-time Chief Executive Officer to direct
the nationalization and other growth programs. The former Chief Executive
Officer and Chairman of the Board of Directors now functions solely as Chairman
providing consulting services at 50.0% of his former salary.

Bad Debt Expense

      Bad debt expense increased by approximately $526,000 from $34,000 in 1995
to $560,000 in 1996. This increase is due to write-offs and adjustments of
$307,000 in 1996 and an increase in the allowance for doubtful accounts of
$219,000. The increase in write-offs and adjustments is due to the write-off of
a receivable from a customer in bankruptcy and the settlement of amounts in
dispute. The increase in the allowance for doubtful accounts relates to
receivables from certain hospitals whose financial condition has deteriorated.

Write Down of Assets

      In March 1997, the Company entered into a sales agreement to sell its
electron beam Accelerator to Shamrock Technologies, Inc. The title to the
Accelerator will pass to the purchaser no later than April 30, 1998, which is
after the end of the current Toll Processing Agreement. The sales price of the
Accelerator was approximately $1,250,000. The Company has charged $103,000 to
its operations to reflect the reduction of the value of the related assets being
sold.

Interest Expense

      Interest expense decreased by approximately $28,000 from approximately
$335,000 for the year ended December 31, 1995 to approximately $307,000 for the
year ended December 31, 1996.

Net Loss

      The Company incurred a net loss of approximately ($995,000) in the year
ended December 31, 1996 compared to net income of approximately $192,000 in the
year ended December 31, 1995. The net loss was mainly the result of costs
incurred to implement its National Sales Program, providing additional reserves
for bad debt losses and costs incurred related to above normal historical levels
of legal expenses from its new legal counsel and additional one time termination
expenses incurred as a result of the elimination of an Officer's position. Also,
the Company added a full-time Chief Executive Officer to direct the
nationalization and other growth programs. The former Chief Executive Officer
and Chairman of the Board of Directors now functions solely as Chairman
providing consulting services at 50% of his former salary.


                                       22
<PAGE>

Net Income (Loss) Applicable to Common Shareholders

      Diluted earnings per share for the year ended December 31, 1996 were
approximately ($0.37), a decrease of $0.39 from the net earnings per share of
$0.02 for the year ended December 31, 1995. Basic earnings per share for the
year ended December 31, 1996 were ($0.37), a decrease of $0.40 from $0.03 in
basic earnings per share for the year ended December 31, 1995. Excluding the
effect of preferred dividends, earnings per share for the year ended December
31, 1996 were ($0.33), a decrease of $0.39 from $0.06 in earnings per share
before the effect of preferred dividends for the year ended December 31, 1995.

Liquidity and Capital Resources

      Current assets have increased approximately $1,206,000 to approximately
$3,849,000 at December 31, 1997 from approximately $2,643,000 at December 31,
1996. The increase was primarily attributable to the classification of
$1,250,000 as current assets held for sale in connection with the sale of the
E-Beam accelerator, an approximate $68,000 increase in prepaid expenses, offset
by an approximate $43,000 decrease in cash, an approximate $18,000 decrease in
net accounts receivable and an approximate $51,000 decrease in inventory.

      The Company had working capital of approximately $1,530,000 at December
31, 1997, compared to working capital of approximately $292,000 at December 31,
1996. The Company's current ratio at December 31, 1997, was 1.66 to 1 compared
to a current ratio of 1.12 to 1 at December 31, 1996. The increase in the
Company's working capital and current ratio at December 31, 1997 compared to
December 31, 1996 was primarily the result of the classification of $1,250,000
as current assets held for sale in connection with the sale of the E-Beam
accelerator, the Company's net income for the year and improved cash flow which
was primarily used to reduce current liabilities.

      The Company currently plans to expand its business by increasing its
portfolio of reprocessing services to include new service offerings such as
consulting, on-site management services and EtO sterilization. The Company
believes that the anticipated future cash flow from operations, along with its
cash on hand and available funds under its working capital line of credit and
the completion of the sale of the electron beam accelerator in April, 1998, will
be sufficient to meet working capital requirements during 1998. There can be no
assurance, however, that the Company will not require additional working capital
and, if it does require such capital, that such capital will be available to the
Company on acceptable terms, if at all.

      Capital expenditures totaled approximately $2,239,000 in 1997 as compared
with approximately $850,000 in 1996. The increase in expenditures was
principally driven by purchases of surgical instruments and containers financed
under a new $1.5 million lease arrangement (See Note 7 to the Financial
Statements). These purchases were primarily made to support the Company's supply
obligations under new contracts entered into during 1997.


                                       23
<PAGE>

      Management plans to purchase additional surgical instruments, as and if
required to support the Company's contract sterilization growth objectives. Cash
flows from operating activities will provide support for these expenditures,
however, additional external financing may also be required. There can be no
assurance, however, that the Company will not require additional working capital
and, if it does require such capital, that such capital will be available to the
Company on acceptable terms, if at all.

Inflation

      The Company does not anticipate that inflation will have any significant
effect on its business particularly since the United States, the only market in
which the Company currently intends to operate, is presently experiencing a
relatively low rate of inflation.

Certain Factors That May Affect Future Results

      From time to time, information provided by the Company, statements made by
its employees or information included in its filings with the Securities
Exchange Commission (including this Form 10-KSB) may contain statements which
are not historical facts, so-called "forward-looking statements," which involve
risks and uncertainties. Forward-looking statements are made pursuant to the
safe harbor provisions of the Private Securities Litigation Reform Act of 1995;
in particular, statements made above in "Item 2. Description of Property"
relating to the suitability of the Company's facilities and equipment for future
operations and the availability of additional facilities and equipment in the
future. Relating to the sufficiency of funds for the Company's working capital
requirements during 1998, the Company's expectation that future cash flow will
continue to be provided from operations and the Company's not presently
anticipating that inflation will have any significant impact on its business may
be forward-looking statements. The Company's actual future results may differ
significantly from those stated in any forward-looking statements. Factors that
may cause such differences include, but are not limited to, the factors
discussed below. Each of these factors, and others, are discussed from time to
time in the Company's filings with the Securities and Exchange Commission.

      The Company's future results are subject to substantial risks and
uncertainties. The Company has operated at a loss or a very small profit for its
entire history and there can be no assurance of its ever achieving consistent
profitability. The Company may require additional working capital in the future
and there can be no assurance that such working capital will be on acceptable
terms, if at all. The failure of the Company to continue to compete effectively
with existing or new competitors could result in price erosion, decreased
margins and decreased revenues, any or all of which could have a material
adverse effect on the Company's business, results of operations and financial
condition. The Company historically has relied on a relatively small number of
customers, including Shamrock and Precision, for a large percentage of its total
revenues. The termination of the Toll Processing Agreement on December 31, 1997
could have a material adverse effect on the Company's results of operations
after 1997. The Company's healthcare provider customers are concentrated in the
Northeast Corridor. Any factors affecting this market generally could have a
material adverse 


                                       24
<PAGE>

effect on the Company's business, results of operations and financial condition.
The Company is subject to government regulation in certain aspects of its
operations. Changes in such regulations could have a material adverse effect on
the Company's business, results of operations and financial condition.

      The Company's future success will depend in part on its ability to
convince hospitals and other healthcare providers to utilize the Company's
off-site sterilization services as opposed to their own on-site facilities.
Hospitals may resist this change for a number of reasons, including the
preferences of hospital staffs which may wish to preserve their existing
staffing, labor unions which may resist any staffing reductions and the ongoing
consolidation of hospitals which may impact the willingness of hospital
administrators to make operational decisions on a timely basis and which may
affect a hospital's decision to utilize an off-site processor as opposed to
retaining one or more of the consolidated hospital group's central sterilization
facilities to provide services for the entire group. The Company relies upon the
know-how of its employees and upon its hospital tracking software to efficiently
conduct its business. Any invalidation of these intellectual property rights or
lengthy and expensive defense of these rights could have a material adverse
effect on the Company.

      The Company's quarterly and annual operating results are affected by a
wide variety of factors that could materially and adversely affect revenues and
profitability, including: competitive pressures on selling prices and margins;
the timing and cancellation of customer orders; the lengthy sales cycle of the
Company's sterilization services to healthcare organizations; the Company's
ability to maintain state-of-the-art sterilization facilities and the
corresponding timing and amount of capital expenditures, particularly if the
Company executes its plan for expansion; and the introduction of new services by
the Company's competitors. As a result of the foregoing and other factors, the
Company may experience material fluctuations in future operating results on a
quarterly or annual basis which could materially and adversely effect its
business, operating results and stock price.

Other Matters

      The Company is currently working to resolve the potential impact of the
year 2000 on the processing of date sensitive information by the Company's
computerized information systems. The potential impacts on key customers and
suppliers are not reasonably estimable at this time. Certain computer programs
have been written using two digits rather than four to define a year which
could, for example, result in a computer system incorrectly recognizing the year
2000 as the year 1900. Costs of resolving the "year 2000" problem are not
currently expected to have a material adverse impact on financial position or
results of operations.

                                    BUSINESS

A. General Development of Business

      The Company provides off-site reprocessing and sterilization of the
Company's Instrument Sets as well as Sterilizable Items for healthcare providers
such as hospitals, hospital networks and ambulatory surgi-centers. See
"Sterilization Services for Healthcare Providers". In 1997 MSI also provided
contract steam, Ethylene Oxide ("EtO"), radiation sterilization services for
manufacturers of disposable medical products such as bandages, sponges,
tracheotomy kits, surgical gloves and laboratory ware. See "Contract
Sterilization of Disposable Medical Products". In addition, in 1997 the Company
utilized its Accelerator to process various industrial products and to perform
certain modifications to those products and to process PTFE. See "Radiation
Processing of Industrial Products". In furtherance of its decision to focus on
its Instrument Set sterilization processing business, on March 17, 1997, MSI
agreed to sell its Accelerator to Shamrock with title to pass no later than
April 30, 1998. Furthermore, in order to maximize the value of its remaining
contract sterilization and industrial processing business and to provide
stability for its accelerator processing customers, on April 9, 1997, MSI
executed a Joint Marketing Agreement with E-BEAM.

      The Company provides its off-site reprocessing and sterilization services
and pre-sterilized reprocessable Instrument Sets to hospitals, hospital networks
and ambulatory surgi-centers in New York, New Jersey, Pennsylvania and the New
England states, Connecticut, Rhode Island, Massachusetts, Vermont, New Hampshire
and Maine (the "Northeast Corridor"). In 1996, the Company made a significant
investment in a national marketing of its services. However, on May 16, 1997,
the Company entered into a Joint Venture Agreement with TFX, a wholly owned
subsidiary of Teleflex setting the terms on which the parties would participate
in the organization, capitalization and operation of a corporation to be known
as SSI. In January, 1997, TFX had acquired all of the Company's outstanding
Convertible Preferred Stock from the previous owner of such stock and in
January, 1997 TFX acquired an additional 150,000 shares of common stock. As a
result, TFX controls approximately 48% of the Company's voting stock. The
purpose of the Joint Venture is to market the offsite reprocessing and
sterilization of surgical instruments and the management of on-site
sterilization services to hospitals and healthcare facilities in all of North
America. The Company's principal territory is the Northeast Corridor, but it has
agreed


                                       26
<PAGE>

with SSI to cooperate on proposals for management of in-house processing for
healthcare providers in the Northeast Corridor. TFX owns 62.5 percent of the
common shares of SSI and the Company owns 37.5 percent. TFX is contributing to
SSI initial operating and project capital and the Company is contributing to SSI
personnel and know-how including its proprietary steri-track system for tracking
instruments in hospitals. In September, 1997, SSI entered into a multi-year
contract to provide total management of a Hospital's sterile processing
functions.

      The Company was founded in May 1982 as a New York corporation. Its
principal executive offices are located at 225 Underhill Boulevard, Syosset, New
York 11791, and its telephone number is (516) 496-8822.

      Statements in this Form 10-KSB which are not historical facts, so-called
"forward-looking statements", are made pursuant to the safe harbor provisions of
the Private Securities Litigation Reform Act of 1995. Investors are cautioned
that all forward-looking statements involve risks and uncertainties, including
those detailed herein and in the Company's other filings with the Securities and
Exchange Commission. See "Item 6. Management's Discussion and Analysis of
Financial Condition and Results of Operations-Certain Factors That May Affect
Future Results".

B. Narrative Description of Business

      The Company presently provides offsite processing and sterilization
services to healthcare providers. As previously stated, through December
31,1997, it also provided processing and sterilization services to manufacturers
of medical disposable products and processed various types of plastic products
through the use of its Accelerator to achieve certain modifications of such
products. The following chart shows the approximate amount and percentage of
total revenues and the net income (loss) for each of the classes of services for
the last two fiscal years:

*     Certain operating expenses as well as certain selling, general and
      administration expenses are not expenses attributable to any class of
      services but have been apportioned among the classes of services. Because
      the sterilization services to health care providers have been growing more
      rapidly than the other services, a greater amount of expenses were
      allocated to the hospital services in 1997. The Company allocated expenses
      to the various categories of service by a variety of methods for example:
      Expenses such as plant rentals and realty taxes are allocated based upon
      square footage used by each service. Utility expenses are allocated by the
      power demands of each service's equipment for which detailed records are
      kept. Product liability insurance is allocated based upon levels of sales
      of each service. Factory maintenance overhead expenses are allocated based
      upon detailed time records kept by the Company. General overhead expenses
      are allocated to each service based upon the relative sales volume of each
      service.

**    The Company has agreed that it will not process PTFE for any other entity
      during and after the termination of its agreement with Shamrock and in
      view of its sale of its Accelerator to be completed April 30, 1998, it
      will no longer sterilize disposable products or process plastic products.

(1) Sterilization Services to Healthcare Providers

      MSI provides off-site cleaning, decontamination and sterilization
processing of the Company's standard containerized reprocessable sterilized
surgical Instrument Sets as well as Sterilizable Items for healthcare providers
such as hospitals and ambulatory surgi-centers within the Northeast Corridor. As
of April 15, 1998, MSI had 21 contracts with healthcare providers in its area of
operations to provide its instrument services for labor and delivery; 22
contracts to provide its instrument services for operating rooms; 3 contracts to
provide laparoscopic instruments; 9 contracts to provide basins; 6 contracts to
provide gowns and/or towels; 2 contracts to provide its instrument services for
open heart and vascular surgery; 4 contracts to provide instrument services for
ambulatory surgery; 3 contracts to provide EtO processing for instruments which
could not be sterilized in a steam sterilizer; and 1 contract to provide
training and consulting of employees in the central sterilizing unit in a
hospital. Future revenues from these contracts as of April 15, 1998 is
approximately $20,227,000. The Company estimates that there are approximately
250 such healthcare providers in the Northeast Corridor.


      Sterilizable Items consist of Instrument Sets, utensils, basins, towels,
surgical gowns and wraps and other items used in healthcare facilities which
require sterilization. Instrument Sets are prepackaged, sterilized,
reprocessable instrument sets, each of which is a complete set of instruments
necessary for a given medical procedure. The Company has designed approximately
85 different Instrument Sets for operating room procedures and labor and
delivery, including gall bladder, tonsillectomy and adenoidectomy, open heart,
vascular,


                                       28
<PAGE>

orthopedic, endoscopy, cesarean sections, newborn delivery, hysterectomy and
dilation and curettage. MSI packages its Instrument Sets in rigid containers
with filters and seals, thereby maintaining sterile integrity without the risk
of tearing and pinholes which occur in more traditional wrappers. The Instrument
Sets aid in the organization of the instruments for ease of use and provide for
better instrument accountability once the procedure is completed. Once an
Instrument Set has been utilized, it is returned to the Company for cleaning,
sterilization and repackaging.

      The Company's services are designed to replace or supplement the existing
in-house sterilization facilities of healthcare providers. Many hospitals have
older, less efficient sterilization facilities, staff their facilities with
nurses whose skills could be more effectively used elsewhere and underutilize
their sterilization facilities by operating their equipment only once per day.
Because of the relatively low volume of sterilization activities undertaken at
many of these facilities, worker productivity may not be as high as in other
areas of the healthcare organization, causing concern for administrators. In
addition, as hospitals continue to evaluate ways in which to utilize their
available space better, many hospitals are seeking to replace their in-house
sterilization facilities with profit generating centers such as operating rooms.
Many hospitals are also looking for ways in which to improve operating room
efficiency by eliminating the sterilization processing delays and shortages
sometimes experienced with their in-house sterilization facilities.

      By utilizing state of the art, industrial size equipment, modern
sterilization technology, less expensive labor, and handling larger volumes, the
Company believes that it offers a cost- effective, high quality alternative to
in-house sterilization facilities. The Company reprocesses Instrument Sets and
Sterilizable Items for numerous customers and has installed modern, industrial
size sterilization equipment at its Syosset facility, including an ultrasonic
cleaning system, two tunnel washers, two 300 cubic foot steam sterilizers and
two 8 cubic foot Ethylene Oxide ("EtO") sterilizers.

      The Company believes that it offers better sterility assurance levels than
those maintained at many hospitals. In order to comply with the infection
control requirements of the Joint Commission on Accreditation of Healthcare
Organizations ("JCAHO"), the Center for Disease Control ("CDC"), the Association
for Advancement of Medical Instrumentation ("AAMI"), the Association of
Operating Room Nurses ("AORN"), the policies and procedures of each respective
hospital as well as the requirements of federal, state and local government
agencies, the Company has established rigorous testing measures and procedures,
such as sterilization process monitors (including temperature and pressure
recording), chemical indicators and bacteriological spore and culture testing.
The Company is a registered contract sterilization facility with the U.S. Food
and Drug Administration ("FDA"), even though neither the Company's activities in
this area nor hospital sterilization facilities are required to be so
registered. See "Government Regulation."

(2)  Contract Sterilization of Disposable Medical Products

      During 1997, MSI provided contract steam, EtO and radiation sterilization
services to manufacturers of disposable medical products. The Company sterilized
disposable medical products such as adhesive and gauze bandages, lap sponges,
absorbent cotton balls, tracheotomy kits, trauma dressings, operating room
drapes, surgical gloves, in vitro diagnostic kits and laboratory ware, such as
pipettes, petri dishes, flasks, roller bottles and tissue culture wells. As of
December 31, 1997, the Company's customers in this area included 39 disposable
medical products manufacturers such Busse Hospital Disposables, Elkay Products,
Inc. and Hermitage Hospital Supply Corp. within a 300 mile radius of its
Syosset, New York facility.

      As heretofore stated, the Company's Board of Directors determined that it
was in the best interests of the Company's shareholders that the Company focus
on its core Instrument Set sterilization processing business. Therefore, the
Company entered into an agreement as of March 17, 1997 to sell its Accelerator
for the approximate sum of $1,250,000 to Shamrock with transfer of title to
occur no later than April 30, 1998. The Company's licenses to operate the
Accelerator were extended to April 30, 1998. In view of the sale of the
accelerator to Shamrock in 1997, the Company evaluated opportunities to maximize
the value of its electron beam related businesses, including its contract
sterilization of disposable medical products unit and its radiation processing
of industrial products unit. As a result, as of April 9, 1997, the Company
entered into a joint marketing program with E-BEAM to provide stability for its
remaining contract sterilization and industrial processing business. The
agreement provided for the transfer of the Company's contract sterilization and
industrial processing customers to E-BEAM at a price of 15% of related revenues
up to $350,000. Upon execution of the agreement the Company received a
nonrefundable down payment against future commissions of $150,000. See
"Management's Discussion and Analysis of Results of Operations and Financial
Condition."



(3) Processing of Plastic Products

      During 1997 MSI performed radiation processing services for 15 industrial
products manufacturers whose products included fabricated plastic objects,
gaskets, tubing and plastic sheet and film. The Company's Accelerator was used
to link chemically a long string of molecules of polyethylene and
polyvinylchloride, to treat crude rubber to achieve bonding and hardening and to
link undivided chemical compounds into a larger chemical entity. See the
previous paragraph regarding the proposed joint marketing agreement with E-BEAM.

      In 1997 the Company's primary radiation processing activity was the
irradiation of PTFE. Once processed, the PTFE can be ground into very small
particles for use primarily as an additive for printing inks and as a lubricant.
The Company processed PTFE for Shamrock and Precision Micron Powers, Inc.
("Precision"), a distributor of PTFE owned by Shamrock, pursuant to a Toll
Processing Agreement, as amended on March 17, 1997. Pursuant to the Toll
Processing Agreement, as amended, MSI processed PTFE only for Precision and
Shamrock, and Precision and Shamrock agreed to use certain minimum levels of
processing


                                       30
<PAGE>

services through December 31, 1997. The income from such services was
$3,040,310 in 1997.

(4) Competition

      The Company's principal competition with respect to its sterilization
services for healthcare providers comes from the in-house sterilization
facilities of hospitals and ambulatory surgi-centers. Most hospitals have an
in-house sterilization capability and many have invested significant capital in
their sterilization facilities. Also, the in-house sterilization facility staff
may be committed to maintaining the facility and its current staffing levels. As
a result, healthcare providers may be reluctant to shift their sterilization
activities from in-house to an off-site contractor. Furthermore, some hospitals
have union agreements that preclude or mitigate a hospital's ability to
outsource. In today's managed care driven, consolidating environment, hospitals
and hospital networks are renegotiating these agreements with yet to be
determined success.

      MSI has no competitor operating in an off-site environment which can
replicate MSI's sterilization services program though variations of the MSI
model potentially exist and/or have been announced in traditional hospital
purchasing news. Sterile Recoveries, Inc., Sterilization Management Group and
Angelica Corp. now compete with the Company in processing gowns, linens and
basins but their operating facilities are all outside the Northeast Corridor.
Substantial know-how and capital intensive barriers could limit competitive
interest. Furthermore, the Company's proprietary hospital tracking software
system gives it a competitive advantage.

      Several small and large companies are specializing in on-site instrument
processing, consulting and management services, providing hospitals and hospital
networks a competitive choice between MSI's off-site instrument processing and
sterilization services. A wholly owned subsidiary of Teleflex, Endoscopic
Specialties Inc. (ESI), specializes in on-site instrument processing. However,
as previously stated MSI and TFX jointly formed SSI to provide instrument
reprocessing in North America and SSI, MSI and ESI have joined to provide a
total instrument management solution for individual hospitals and hospital
networks throughout North America.

Suppliers

      The Company purchases from surgical instrument manufacturers the surgical
instruments included in Instrument Sets that are provided to hospitals and
ambulatory surgi-centers. The Company believes that such instruments are readily
available at market prices.

Sales and Marketing

      MSI's sales and marketing strategy is to grow existing accounts by service
expansion: for example, if the Company is serving the labor and delivery
department of a hospital it will attempt to leverage its services into the
general operating room of the hospital after a period of


                                       31
<PAGE>

successful product performance in the labor and delivery area. The Company has
expanded its portfolio of reprocessing services to include new service offerings
such as consulting, on-site management services and EtO sterilization. The
Company's sales and marketing efforts are coordinated by sales professionals
with appropriate clinical and hospital expertise.

      Furthermore, the Company entered into a joint venture with TFX to form SSI
to sell MSI's decontamination, reprocessing and sterilizing services in select
highly populated urban centers in North America and is cooperating with SSI to
market management services in the Northeast Corridor.

Intellectual Property

      The Company does not rely on any patents for the conduct of its business.
The Company does rely upon the know-how of its employees and has executed
non-disclosure and non-competition agreements with its employees. The Company
relies in significant part upon its hospital tracking software which allows the
Company to monitor and control the levels of Instrument Sets and Sterilizable
Items on-site with a given customer and to plan and control sterilization
activities. The Company's hospital tracking software was purchased from its
developer and the copyrights were assigned to the Company. Although the Company
believes that it has all necessary ownership and copyright rights in its
hospital tracking software and that this software does not infringe upon the
intellectual property rights of third parties, any determination to the contrary
could have a material adverse effect on the Company's business, results of
operations and financial condition.

(5)  Employees

      As of April 15, 1998, the Company had 86 full-time and 27 part-time
employees. Management believes its relations with its employees are good. None
of its employees are covered by any collective bargaining agreement.

(6) Government Regulations

      The Company has obtained a license from the New York State Department of
Environmental Conservation operating through the Nassau County Department of
Health to operate its radiation sterilization and processing facility. This
license is currently in force and will remain in force until April 30, 1998. The
Company believes it is in material compliance with applicable laws and
regulations with respect to its radiation sterilization and processing facility.
The Company believes that it is in material compliance with the regulations of
the Nassau County Department of Public Works with regard to the disposition of
effluents.

      The Company is registered with the Department of Health and Human
Services, Public Health Service of the FDA, and believes it is in material
compliance with the FDA compliance program with regard to the industrial
sterilization of medical devices. With regard to the reprocessing of instrument
sets for hospitals, the Company complies with the FDA's program


                                       32
<PAGE>

even though, for these purposes, a hospital (and the Company, by extension) is
not considered to be a manufacturer of medical devices and is, therefore, not
subject to the FDA regulations.

      The Company is also subject to the requirements of the Occupational Safety
and Health Administration ("OSHA") and believes that it is in material
compliance with OSHA. The Company believes that it is in material compliance
with all other applicable federal, state and local rules and regulations
relating to the conduct of its business.

(7) Insurance

      The Company carries a general liability policy of $1,000,000 with
additional coverage of $6,000,000. To date, there have been no liability claims
resulting from the use of the Company's services.

(8) Property

      The Company's headquarters, including its executive offices, sterilization
facility and radiation processing facility, occupy approximately 103,000 square
feet of leased space in a building located at 225 Underhill Boulevard, Syosset,
New York. The Company originally entered into its headquarters lease on March 1,
1984. On November 20, 1995, the Company executed a new lease for its
headquarters which provides for a term of March 1, 1996 through February 28,
2001 with an annual rent of $456,000 for the first three years and $504,000 for
the next two years.

      The Company believes that its facilities and equipment are in good
condition and are suitable for its operations as presently conducted and for its
foreseeable future operations. The Company currently believes that additional
facilities and equipment can be acquired if necessary, although there can be no
assurance that additional facilities and equipment will be available upon
reasonable or acceptable terms, if at all.

                                LEGAL PROCEEDINGS

      In management's opinion, there are no pending claims or litigation, the
adverse determination of which would have a material adverse effect on the
financial position or results of operations of the Company.

MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED SHAREHOLDERS' MATTERS

      The Company's Common Stock, $.01 par value per share, has been traded in

Employment Contracts and Termination of Employment Arrangements

      In September, 1994, the Company entered into a transition agreement with
its then President and Chief Executive Officer, Kennard H. Morganstern. Pursuant
to the agreement Dr. Morganstern resigned as President on September 8, 1995 upon
the election of D. Michael Deignan as President. Dr. Morganstern resigned as
Chief Executive Officer on December 31, 1995 at which time Mr. Deignan became
Chief Executive Officer. The agreement provides that for a period of three years
commencing September 8, 1995, Dr. Morganstern will continue to serve as Chairman
of the Board and, at the option of the new President, make available 50% of his
time for consulting purposes. During this period he will receive a base annual
compensation of 50% of his former compensation, or $75,000, together with normal
benefits provided to other officers of the Company.

      Mr. Deignan does not have a long-term employment agreement with the
Company. His employment may be terminated by the Company at any time. The
Company's policy is to make a severance payment of nine months' base salary and
benefits to Messrs. Deignan and Fogarty if their employment is terminated by the
Company.

                      THE 1994 AND 1996 STOCK OPTION PLANS

      On September 29, 1994, the Board of Directors approved the Medical
Sterilization, Inc. 1994 Stock Option Plan (the "1994 Plan) and authorized the
issuance or up to 1,000,000 shares upon the exercise of options granted under
the Plan. The 1983 Stock Option Plan, which authorized the issuance of up to
800,000 shares upon the exercise of options, expired by its terms on May 11,
1993. On July 20, 1995, the shareholders approved the 1994 Stock Option Plan. On
March 31, 1996 the Board of Directors approved the 1996 Stock Plan (the "1996
Plan") and the authorization of 500,000 shares to be issued on exercise of
options granted under the 1996 Plan. This Plan succeeded the 1994 Stock Option
Plan which had no shares remaining available for option grants. The 1996 Stock
Option Plan was approved by shareholders on May 30, 1996.

                              GRANTS UNDER THE PLAN

      Incentive Stock Options ("ISO") may be granted by the Compensation
Committee of the Board of Directors to officers and employees of the Company. An
ISO granted under the Plan may be exercisable immediately or in installments
following a period of two years after grant but must expire within ten years
from the date it is granted (five years in the case of such options granted to
holders of more than 10% of the Company's voting stock). Except in certain
circumstances an ISO may only be exercised so long as the employee continues to
be employed by the Company. The exercise price of such option must be at least
equal to the fair market value of the Company's Common Stock on the date such
option was granted (110% in the case of 10% shareholders) and must be paid in
cash or in stock of the Company valued at its then fair market value. An
employee may not receive ISOs to purchase stock having a maximum fair market
value in excess of $100,000 in any calendar year, with certain exceptions. The
options are non-transferable except by will or by the laws of descent and
distribution. The options terminate three months after the optionee's
relationship with the Company is terminated except if termination is by reason
of total disability or death. In the event of disability, under the 1994 Plan an
option must be exercised within one year after disability. Under the 1996 Plan
exercise must be before the earlier of the specified expiration date or 180
days. In the event of death, both Plans require the exercise to be before the
earlier of the expiration date or 180 days after death.

      In addition, the Compensation Committee may issue Non-Statutory Stock
Options under the Plan. The exercise price of these stock options is not limited
and may be below fair market value but cannot be less than the minimum legal
consideration required under the law of the State of New York. These options may
be granted to directors, officers, consultants and key employees of the Company.

      The exercise of a Non-Statutory Stock Option would result in ordinary
income for the grantee and a deduction for the Company measured by the
difference between the option price and the fair market value of the shares
received at the time of exercise. Income tax withholding would be required.

      The exercise of an ISO would not result in income for the grantee if the
grantee (i) does not dispose of the shares within two years after the date of
grant or one year after the transfer of shares upon exercise and (ii) is an
employee of the Company from the date of grant until three months before the
exercise date. If those requirements are met, the basis of the shares upon later
disposition would be the option price. Any gain will be taxed to the employee as
long-term capital gain and the Company would not be entitled to a deduction. The
excess of the market value on the exercise date over the option price is an item
of tax preference, potentially subject to the alternative minimum tax.

      If the grantee disposes of the shares prior to the expiration of either of
the holding periods, the grantee would recognize ordinary income and the Company
would be entitled to a deduction equal to the lesser of the fair market value of
the shares on the exercise date minus

                                       39
<PAGE>

the option price or the amount realized on disposition minus the option price.
Any gain in excess of the ordinary income portion would be taxable as longterm
or shortterm capital gain.

      As of April 15, 1998, there were Non-Statutory Options to purchase 692,500
shares of stock at prices ranging from $.74 to $9.00 and Incentive Stock Options
to purchase 157,500 shares at $.74 per share, 75,000 shares at $.75 per share,
and 134,670 shares at $1.06 per share and 118,500 shares at $1.28 per share.

Compensation of Directors

      On May 22, 1997, the Board of Directors approved the grant of a
Non-Statutory Stock Option to purchase 15,000 shares of common stock of the
Company at the price of $1.50 per share to each of John R. Hoover and Forrest R.
Whittaker, the two outside directors. Each option became exercisable on December
31, 1997. The grant replaces the participation fee of $500.00 per meeting paid
to the directors prior to May 22,1997. All directors are reimbursed for expenses
in connection with attending Board and Committee meetings.

      On January 17, 1996, the Company granted Mr. Whittaker a warrant to
purchase 25,000 shares of Common Stock at $2.00 per share, which is now
exercisable in full. Grants of options to Directors are set forth under Option
Grants, supra.

      The Company has purchased directors' and officers' liability insurance
from National Union Fire Insurance Corporation of Pittsburgh, PA covering all of
the Company's directors and officers. The aggregate premium for this insurance
policy in 1997 was $26,000.

                              PLAN OF DISTRIBUTION

      It is anticipated that the Selling Shareholders will individually offer
the securities presently owned by them in the manner set forth on the cover page
of this Prospectus, from time to time in the over-the-counter market at prices
prevailing at the time of sale, or in private transactions at negotiated prices.
In addition, Shares to be issued on the exercise of warrants or options or the
conversion of the Series B and C Stock may also be offered for resale by the
Selling Shareholders in the same manner. The cost of such sales is to be borne
by the Selling Shareholder. The costs of registering the Shares under the
Securities Act are to be borne by the Company. The Company will not receive any
proceeds from the sale of such Shares.

                            DESCRIPTION OF SECURITIES

                                  COMMON STOCK

      The Company is authorized to issue 10,000,000 shares of Common Stock, par
value of $0.01 per share. As of April 1, 1998 there were 3,170,496 shares
outstanding. Shareholders have no preemptive rights. The outstanding shares of
the Common Stock are and the Shares offered hereby by the Selling Shareholders
will, when issued, be fully paid and nonassessable.


                                       43
<PAGE>

Voting rights, Non-Cumulative Voting

      Holders of shares of Common Stock of the Company are entitled to cast one
vote for each share held at all shareholders' meetings for all purposes,
including the election of directors. The Common Stock does not have cumulative
voting rights which means that the holders of more than 50% of the Common Stock
can elect 100% of the directors of the Company if they choose to do so subject
to the rights of the Preferred shareholders, as hereinafter set forth. The
Bylaws of the Company require that only a majority of the issued and outstanding
shares of the Company be represented to constitute a quorum and to transact
business at a shareholders' meeting. The Series B and C Shareholders shall vote
together with the common shareholders with each Preferred Shareholder having the
number of votes per share as shall equal the number of shares of Common Stock
into which the Preferred Stock is then converted. The officers and directors of
the Company and TFX own approximately 66.34% of the outstanding shares of Common
Stock assuming exercise of all options, warrants and conversion of all Preferred
Stock. As a practical matter, such group could be in a position to elect all of
the directors of the Company and control its policies. Furthermore, the Series B
and C Shareholders have the right to elect three directors of the seven
authorized pursuant to the Amended Certificate of Incorporation filed in
November, 1994 and the consent of the prior holders of the Preferred Shares
executed September 8, 1995.

Dividends

      The Company has not paid any dividends on the Common Stock and anticipates
that for the foreseeable future any earnings will be retained for use in its
business. Certain of the Company's loan agreements and the terms of the Series B
and C Stock prohibit the payment of dividends on the Common Stock. See also
Paragraph 4D in "PREFERRED STOCK" on page 46 infra regarding dividends on Common
Stock.

Liquidation Rights

      In the event of any distribution of capital assets, whether voluntary or
involuntary, after creditors have been paid in full and any distribution to
holders of the Preferred Stock, the common shareholders are entitled to share
equally. Upon liquidation or dissolution, each outstanding share of Common Stock
will be entitled to share equally in the assets of the Company legally available
for distribution to shareholders after the payment of all debts and other
liabilities and the payment of $2.00 per share plus an amount equal to all
Accruing Dividends unpaid to the holders of the Series B Stock and the payment
of $1.00 per share to the holders of the Series C Stock. See Paragraph 3 in
"PREFERRED STOCK" on page 46.

Transfer Agent

      The transfer agent for the Common Stock of the Company is American Stock
Transfer & Trust Company, 99 Wall Street, New York, New York 10005. The transfer
agent for the Series B and Series C Stock is Harvey Cohen, Esq., 1100 Franklin
Avenue, Suite 303, Garden City, New York 11530.

                                    WARRANTS

      The Company has outstanding warrants to purchase an aggregate of 355,000
shares of Common Stock. The number of shares has, and the exercise prices have,
been adjusted by reason of the anti-dilution provisions of the warrant
agreements and agreement with some of the warrant holders. At this time all
warrants are exercisable at $2.00 per share. The shares of stock being
registered hereunder include the shares underlying the outstanding warrants.

      (1) In July, 1990, as consideration for the five year $700,000 term loan
and extension and increase to the revolving line of credit made to the Company,
warrants to purchase an aggregate of 100,000 shares of the Company's Common
Stock at $3.00 per share, exercisable through July 20, 1995, were issued to
Apple Bank for Savings. In September, 1994, the exercise date of the warrants
was extended to July 20, 1998 and the exercise price was reduced to $2.00 per
share.

      (2) On September 29, 1994, warrants to purchase 40,000 shares of Common
Stock at $2.00 per share were issued to each of John R. Hoover, a Director, and
Harvey Cohen, then a Director of the Company, in connection with services
rendered in the settlement of the Shamrock judgment.

      (3) On November 29, 1994, in connection with an agreement with Rosenthal &
Rosenthal, Inc. ("R&R") calling for a revolving secured line of credit of
$2,000,000, MSI issued warrants to R&R to purchase 50,000 shares of Common Stock
at $2.00 per share.

      (4) On November 29, 1994, as part of the settlement of the judgment of
approximately $3,752,000, including interest, held by Shamrock, MSI issued
warrants to Shamrock to purchase 75,000 shares of Common Stock at $2.00 per
share.

      (5) On February 8, 1995, MSI issued to William R. Lonergan, a newly
elected director, warrants to purchase 25,000 shares of Common Stock at $2.00
per share.

      (6) On January 17, 1996 MSI issued to Forrest R. Whittaker, a newly
elected Director, warrants to purchase 25,000 of Common Stock at $2.00 per
share.

      The warrant holders have advised the Company that stock received by them
upon the exercise of their warrants may be sold from time to time in the
over-the-counter market at prices prevailing at the time of sale, or in private
transactions at negotiated prices; that they have not entered into any
arrangements with any underwriters with respect to the sale of any of the
Shares; and that any commissions or discounts given or other expenses of sale
will be those customary in the type of transaction involved and will be paid by
the selling warrant holders. The Company will receive approximately $710,000 if
all the warrants are exercised. Although, in view of the fact that the warrant
prices are in excess of current market prices for the Company's stock, it is
unlikely that any warrants will be exercised unless market prices improve
significantly. The warrant holders and brokers and dealers through whom such
Shares are sold may be deemed "underwriters" within the meaning of the
Securities Act of


                                       45
<PAGE>

1933, as amended, with respect to sales, and any profits realized or commissions
received may be deemed underwriting commissions.

      Unless otherwise noted, none of the warrant holders has any relationship
to the Company other than as a holder of its securities.

                                 PREFERRED STOCK

      In December, 1989, the Company issued 333,334 shares of Series A Stock in
exchange for a convertible demand note issued in January, 1989. In December,
1989, the Company issued 333,333 shares of Series A Stock for $1,000,000
collected in January, 1990. In December, 1989, debt aggregating $500,000 was

restructured its Series A Stock (as of June 30, 1994 values) which was due to be
redeemed on December 31, 1994. Of the 800,000 shares of existing Series A Stock,
750,000 shares plus accrued dividends of $1,071,094 were exchanged for two new
series of Convertible Preferred Stock. The remaining 200,000 authorized shares
of Series A Stock were cancelled. $1,375,000 of the original principal amount of
$2,400,000 was exchanged for $1,375,000 of Series B Stock, as a result of a
further exchange. This Series B Stock is now convertible at the option of the
holder into 687,500 shares of Common Stock or cash, at $2.00 per share maturing
December 30, 1999. Dividends accrue on this Series B Stock at the rate of 8% per
year. These dividends may be paid in cash or accrued at the option of the
Company. If not paid, they will be added to the face amount of the Series B
Stock at the price of $2.00 per share at the time of conversion. $1,945,625 of
the Series A Stock and accrued dividends were exchanged for what is now
1,945,625 shares of Series C Stock. The Series C Stock is automatically
convertible at $1.00 per share into 1,945,625 shares of Common Stock on December
30, 2004, or earlier at the option of the holder. There are no dividends payable
or accrued on the Series C Stock. At December 31, 1994, the balance due on the
50,000 outstanding shares of Series A Stock and accrued dividends aggregating
$225,000 were converted into a one (1) year term loan with monthly principal and
interest payments. The loan bore interest at the rate of prime plus 3 1/2%. The
loan has been paid in full.

      9. Registration Rights. Pursuant to the Registration Rights Agreement, the
Company has agreed to include the Common Stock issuable on conversion of the
Series B and Series C Stock in any registration of its securities.

      The holders of Series B and Series C Stock have advised the Company that
stock received by them upon the conversion of the Series B and Series C Stock
may be sold from time to time in the over-the-counter market at prices
prevailing at the time of sale, or in private transactions at negotiated prices,
that they have not entered into any arrangements with any underwriters with
respect to the sale of any of the Shares and that any commissions or discounts
given or other expenses of sale will be those customary in the type of
transaction involved and will be paid by the Selling Shareholders. The Company
will not receive any of the proceeds of sale. The holders and brokers and
dealers through whom such Shares are sold may be deemed "underwriters" within
the meaning of the Securities Act of 1933, as amended, with respect to sales,
and any profits realized or commissions received may be deemed underwriting
commissions.

                              SELLING SHAREHOLDERS

      The Selling Shareholders are shareholders of the Company who have acquired
Shares, which are not registered, either upon the exercise of options and
warrants, conversion of Series A Stock or upon purchase of said Shares on a
private placement by the Company. The Selling Shareholders also include those
persons who may acquire Shares upon the exercise of options or warrants or the
conversion of Series B and C Stock. If the Selling Shareholders sell the Shares
held by them or to be received by them, it will be deemed a secondary offering
by such shareholders.

      In connection with the proposed sale by the Selling Shareholders of the
Shares, the Company has agreed to keep the Registration Statement, of which this
Prospectus is a part, effective with respect to such Shares until nine months
after the date of this Prospectus. The Selling Shareholders have advised the
Company that they have no present intention of selling their Shares but that
their Shares may be sold from time to time in the over-the-counter market at
prices prevailing at the time of sale, or in private transactions at negotiated
prices, that they have not entered into any arrangements with any underwriters
with respect to the sale of any of the Shares and that any commissions or
discounts given or other expenses of sale will be those customary in the type of
transaction involved and will be paid by the Selling Shareholders. The Selling
Shareholders and brokers and dealers through whom such Shares are sold may be
deemed "underwriters" within the meaning of the Securities Act of 1933, as
amended, with respect to sales, and any profits realized or commissions received
may be deemed underwriting commissions.
      Unless otherwise noted, none of the Selling Shareholders has any
relationship to the Company other than as a holder or its securities.

pursuant to the foregoing provisions, the Company has been informed that in the
opinion of the Commission such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

Indemnification of Directors and Officers

      Section 726 of the Business Corporation Law of the State of New York
grants each corporation organized thereunder, such as the Company, the power to
indemnify its directors and officers against liabilities for certain of their
acts. Article XII of the Company's Bylaws provides for indemnification of
officers and directors of the Company, to the extent permitted by Section 726
and establishes certain procedures to comply therewith.

      Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the registrant's bylaws or the law of the State of
New York, or otherwise, the registrant has been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

Other Expenses of Insurance and Distribution

      The estimated expenses of the registrant in connection with the
registration of the Common Stock registered hereby are as follows:

           Legal Fees and Expenses                              $ 6,000
           Accounting Fees and Expenses                           1,000
           Blue Sky Fees and Expenses                             1,000
           Cost of Copying                                        1,000

                                          Total                 $10,000

C. Warrants

      As part of the restructuring of Preferred Stock in November, 1994,
warrants to purchase 800,000 shares of Common Stock held by the Preferred
Shareholders were cancelled.

      The following warrants have been issued:

      (1) In July, 1990, as consideration for the five year $700,000 term loan
and extension and increase to the revolving line of credit made to the Company,
warrants to purchase an aggregate of 100,000 shares of the Company's Common
Stock at $3.00 per share, exercisable through July 20, 1995, were issued to
Apple Bank for Savings. In September, 1994, the exercise date of the warrants
was extended to July 20, 1998 and the exercise price was reduced to $2.00 per
share.

      (2) On September 29, 1994, warrants to purchase 40,000 shares at $2.00 per
share were issued to each of Harvey Cohen and John R. Hoover, Directors, in
connection with their services during the negotiation of the settlement of the
judgment held by Shamrock. These warrants are exercisable through September 29,
1999.

      (3) On November 29, 1994, in connection with an agreement with Rosenthal &
Rosenthal, Inc. ("R&R"') calling for a revolving secured line of credit of

D. Preferred Stock

      In November, 1994, the Company restructured its Series A Convertible
Preferred Stock (as of June 30, 1994 values) which was due to be redeemed on
December 31, 1994. Of the 800,000 shares of existing Series A Convertible
Preferred Stock, 750,000 shares, plus accrued dividends of $1,071,094 were
exchanged for two (2) new series of Convertible Preferred Stock. The remaining
200,000 authorized shares of Series A Convertible Preferred Stock were
cancelled. $1,375,000 of the original principal amount of $2,400,000 was
exchanged for $1,375,000 of Series B Convertible Preferred Stock. This Series B
Convertible Preferred Stock is convertible at the option or the holder into
687,500 shares of Common Stock or cash, at $2.00 per share maturing December 30,
1999. Dividends accrue on this Series B Convertible Preferred Stock at the rate
of 8% per year. These dividends may be paid in cash or accrued at the option of
the Company. If not paid, they will be added to the face amount of the Series B
Convertible Preferred Stock at the price of $2.00 per share upon conversion.
$1,945,625 of the Series A Convertible Preferred Stock and accrued dividends
were exchanged for 1,945,625 shares of Series C Convertible Preferred Stock. The
Series C Convertible Preferred Stock is automatically convertible at $l.00 per
share into 1,945,625 shares of Common Stock on December 30, 2004, or earlier at
the option of the holder. There are no dividends payable or accrued on the
Series C Convertible Preferred Stock. At December 31, 1994, the balance due on
the 50,000 outstanding shares of Series A and accrued dividends aggregating
$225,000 was converted into a one (1) year term loan with monthly principal and
interest payments. The loan has been paid in full.

      In November 16, 1994, the following shares of Series B and Series C
Convertible Preferred Stock were issued to named shareholders in exchange for
their Series A Convertible Preferred Stock.

Undertakings

      1. The undersigned registrant hereby undertakes:

            (a) To file, during any period in which offers or sales are being
made, a posteffective amendment to this Registration Statement; (i) to include
any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii)
to reflect in the prospectus any facts or events arising after the effective
date of the Registration Statement (or the most recent posteffective amendment
thereof) which, individually or in the aggregate, represent a fundamental change
in the information set forth in the Registration Statement; and (iii) to include
any material information with respect to the plan of distribution not previously
disclosed in the Registration Statement or any material change to such
information in the Registration Statement.


                                       61
<PAGE>

            (b) That, for the purpose of determining any liability under the
Securities Act of 1933 each such posteffective amendment shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

            (c) To remove from registration by means of a posteffective
amendment any of the securities being registered which remain unsold at the
termination of the 1994 Stock Option Plan or at the termination of the offering.

      2. The undersigned registrant also undertakes:

            (a) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 (the "Act") may be permitted to directors, officers and
controlling persons of the small business issuer pursuant to the foregoing
provisions, or otherwise, the small business issuer has been advised that in the
opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Act and is, therefore, unenforceable.

            (b) In the event that a claim for indemnification against such
liabilities (other than the payment by the small business issuer of expenses
incurred or paid by a director, officer or controlling person of the small
business issuer in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with the
securities being registered, the small business issuer will, unless in the
opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

position of Medical Sterilization, Inc. at December 31, 1997 and the results of
its operations and its cash flows for the year then ended, in conformity with

                          NOTES TO FINANCIAL STATEMENTS

1. Formation and Business:

      The Company was incorporated in New York State on May 27, 1982. The
Company provides off-site sterilization services to health care providers and
through 1997 provided sterilization services to manufacturers of disposable
medical products and various industrial products, principally in the New York
metropolitan area. The Company also used its radiation facility at Syosset, New
York, to irradiate PTFE, which can then be ground into very small particles for
use primarily as an additive to printing inks and as a lubricant. The Company
leases its facility in which it has installed steam, EtO and radiation
sterilization equipment.

      For the fiscal year ended December 31, 1997, the Company's sterilization
services for healthcare providers, contract sterilization of disposable medical
products and radiation processing of industrial products businesses accounted
for approximately 58.8%, 10.4% and 30.8%, respectively, of the Company's
revenues, as compared with 55.1%, 11.0% and 33.9%, respectively, for the fiscal
year ended December 31, 1996.

2. Summary of Significant Accounting Policies:

      Inventory:

      Inventory is stated at the lower of first-in, first-out cost or market.

      Fixed Assets:

      Depreciation and amortization are computed using the straight-line method
over the estimated useful lives of the related assets (ranging from 5 to 15
years) and, for leasehold improvements, over the shorter of the useful life of
the improvement or the term of the lease. Shrinkage-loss of surgical instruments
and containers is provided based upon incurred losses.

      Maintenance and repairs are charged to expense in the year incurred.
Expenditures which significantly improve or extend the life of the assets are
capitalized. Upon disposal, the cost and related accumulated depreciation are
removed from the respective accounts and any resulting gain or loss is included
in income.


                                      F-9
<PAGE>

      Accounting for Long-Lived Assets:

      On a periodic basis or whenever changes in circumstances indicate that the
carrying amount of an asset may not be recoverable, impairment is evaluated by
comparing future cash flows (undiscounted and without interest charges) expected
to result from the use or sale of the asset and its eventual disposition, to the
carrying amount of the asset.

      Earnings Per Share Calculation:

      In February 1997, the Financial Accounting Standards Board issued
Statements of Financial Accounting Standards No. 128, "Earnings per Share"
("SFAS No. 128"), which establishes standards for computing and presenting
earnings per share. SFAS No. 128 requires presentation of both basic and diluted
earnings per share. Basic earnings per share is computed by dividing net income
by the weighted average number of common shares outstanding during the period.
Diluted earnings per share is computed in a similar manner except that the
weighted average number of common shares is increased for dilutive securities.
Potentially dilutive securities for the 1997 computation of diluted earnings per
share consist of options for 468,062 shares and Series C Convertible Preferred
Stock for 1,945,625 shares. Series B Preferred Stock was excluded from the 1997
calculation of diluted earnings per share since the result would be
anti-dilutive. Potentially dilutive securities have also been excluded from the
1996 computation of diluted earnings per share since the result would be
anti-dilutive.

      Revenue Recognition:

      The Company records revenue for hospital services monthly, in accordance
with contractual terms. Revenues for other sterilization and radiation services
are recorded upon the completion of processing and/or shipment.

      Concentration of Credit Risk:

      Trade receivables arise from long-term and short-term contracts with
healthcare providers in its area of operations. The Company provided instrument
sterilization services pursuant to approximately 71 sterilization services
contracts with hospitals and ambulatory surgi-centers during 1997 as compared to
approximately 53 during 1996. In addition, the Company sterilized disposable
medical products and processed industrial products for approximately 54
disposable medical products manufacturers and industrial companies during 1997
as compared to approximately 66 during 1996. Receivables also arise from the
processing of Teflon. This process is performed solely for Shamrock (See Note
13), and accounted for approximately 30.8% and 33.9% of total revenue for 1997
and 1996, respectively. To reduce credit risk, the Company performs credit
evaluations of its customers but does not generally require collateral. Credit
risk is affected by conditions within the economy and the healthcare industry.
The Company establishes an allowance for doubtful accounts based upon factors
surrounding the credit risk of specific customers, historical trends and other
information.

At December 31, 1997, six customers represented approximately 50% of the
accounts receivable balance. The loss of any one customer could have a
significant impact on the Company's financial position or results of operations.

      Income Taxes:

      The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes", which
requires that deferred income taxes be recognized for the tax consequences in
future years of differences between the tax bases of assets and liabilities and
their financial reporting amounts at each year-end based on enacted tax laws and
statutory rates applicable to the periods in which the differences are expected
to affect taxable income. Valuation allowances are established when necessary to
reduce deferred tax assets to the amount expected to be realized.

      Use of Estimates:

      The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities,
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

      Reclassifications:

      Certain items in the 1996 financial statements have been reclassified to
conform with the 1997 presentation of the financial statements.

3. Fixed Assets:

      At December 31, 1997, fixed assets consists of:

      Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amount of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
the Company's deferred tax assets and liabilities at December 31, 1997 are as
follows:

      Deferred tax liability:
        Depreciation                                                $  (996,641)

      The Company has established a valuation allowance equal to the net
deferred tax asset amount as it is more likely than not that the deferred tax
asset will not be realized. During 1997 the Company utilized approximately
$319,000 of net operating loss carryforwards for income tax purposes. Such
utilization served to eliminate the Company's current tax liability


                                      F-12
<PAGE>

except for the alternative minimum tax. The net change in the total valuation
allowance for the year ended December 31, 1997 was a decrease of approximately
$125,000 related primarily to current year net operating loss carryforwards.

      At December 31, 1997, the Company had federal net operating loss
carryforwards of approximately $10,272,000, which expire in varying amounts from
1998 through 2012.

6. Long-Term Debt:

      At December 31, 1997, long-term debt consists of:

      Note payable to officer and shareholder, payable in annual
       installments of $50,000 with interest payable monthly at the

      Note payable to TFX, payable in installments as follows:
       $50,000 on February 1, 1998 and three successive
       installments of $50,000 on the same day of each succeeding
       calendar month until all such payments have been made, and
       on May 8, 1998, the entire balance of principal and
       interest unpaid shall be due and payable, at the rate of
       1% per annum over the prime rate.                                 400,000
                                                                      ----------

            Less, current maturities (including $450,000 due
             to related parties)                                         901,836

            Long-term debt (including $49,741 due to
             related parties)                                         $1,450,009
                                                                      ==========

      (a) Repayment terms are restricted at a rate not to exceed 10% of the
profits in any quarter and to be limited further by the Company's cash
availability. The loans are subordinate to the bank borrowing.


                                      F-13
<PAGE>

      (b) The bank holds a second lien position on the Company's assets and a
first lien on proceeds to be received from the divestiture of the Company's
electron beam accelerator (See Note 13). The weighted average interest rate for
the year ended December 31, 1997 was 11%.

      (c) The agreement provides for a revolving collateralized line of credit
up to $2,000,000. The line of credit is collateralized by substantially all
assets of the Company. In October, 1997, the agreement was modified and extended
to January 31, 2000, and the advance rate on the Company's eligible Accounts
Receivable was increased to 85% from the existing 75%. The interest rate on the
facility was also changed to prime plus 2% (previously prime plus 3.5%). The
agreement prohibits the payment of dividends on the shares of Common Stock.

      Average monthly borrowings under the revolving line of credit described
above for the year ended December 31, 1997 amounted to $1,630,387 and the
related weighted average interest rate was 11.9%. Maximum borrowings at any
month end were $1,903,010 in 1997.

      Aggregate principal payment requirements for long-term debt are as
follows: 1998 - $901,836; 1999 - $49,741; 2000 - $1,400,268; and thereafter -
$0.

      Fair value of long-term debt approximates recorded amounts as similar
borrowings have been offered to the Company at comparable rates and maturities.

7. Capital Leases:

      Future minimum payments as of December 31, 1997 under capital leases for

      In April 1997, the Company entered into a new master lease agreement with
a bank to finance the purchase of surgical instruments and containers.
Approximately $1,500,000 was drawn under this arrangement during 1997. The lease
agreement is guaranteed by Teleflex, the parent of TFX, the Company's major
shareholder.

8. Common and Preferred Stock:

      On January 8, 1997, TFX, a wholly owned subsidiary of Teleflex, a
diversified publicly held company, purchased the Series B and Series C
Convertible Preferred Stock from the previous owners of such stock. In
connection with this transaction and after the resignation of three of the
incumbent Directors, three nominees of TFX, were elected to the Company's Board
of Directors.

      The Series B Convertible Preferred Stock is convertible at $2.00 per share
into 687,500 shares of Common Stock. This Series B Convertible Preferred Stock
is convertible at the option of the holder into Common Stock or cash, at $2.00
per share maturing December 31, 1999. Dividends accrue on the Series B
Convertible Preferred Stock at the rate of 8% per year. These dividends may be
paid in cash or accrued at the option of the Company. If not paid, accrued
dividends are added to the face amount of the Series B Convertible Preferred
Stock at the time of conversion. In the event prior to October 31, 1999, the
market price of the Company's Common Stock as quoted on Nasdaq attains a price
of $6.00 per share and maintains such price for at least 90 days, the Series B
Convertible Preferred Stock will be automatically converted into Common Stock.

      The Series C Convertible Preferred Stock is automatically convertible at
$1.00 per share into 1,945,625 shares of Common Stock on December 30, 2004, or
earlier at the option of the holder. There are no dividends payable nor accrued
on the Series C Convertible Preferred Stock. In the event prior to October 31,
1999, the market price of the Company's Common Stock as quoted on Nasdaq attains
a price of $3.00 per share and maintains such price for at least 90 days, the
Series C Convertible Preferred Stock will be automatically converted into Common
Stock.

      In February 1997, the Company issued an additional 150,000 shares of its
common stock to TFX for $2.00 per share. The shares were used to reduce amounts
payable to another subsidiary of Teleflex, incurred for surgical instrument
purchases.

9. Common Stock Warrants:

      From time to time, the Company has issued Common Stock warrants to
directors, lending institutions and other third parties. In January 1996, the
Company issued warrants to purchase 25,000 shares of Common Stock at $2.00 per
share to a new board member. Such warrants become exercisable as follows: 25% in
1996, 25% in 1997, 25% in 1998 and 25% in 1999. The warrants expire in 2001. No
Common Stock warrants were issued in 1997.

      At December 31, 1997, the Company had aggregate warrants outstanding to
purchase 357,500 shares of Common Stock at a price of $2.00 per share with
expiration dates through January 2001.

10. Stock Option Plan:

      On September 29, 1994, the Board of Directors approved the 1994 Stock
Option Plan and authorized the issuance of up to 1,000,000 shares of Common
Stock of the Company upon the exercise of Incentive and Non-Qualified Stock
Options which may be granted pursuant to the Plan. The Plan was approved by the
shareholders at a meeting held on July 20, 1995. In 1996, the Board of Directors
authorized another 500,000 shares of Common Stock to be issued under the 1996
Plan which was approved by shareholders on May 25, 1996.

      Incentive Stock Options may be granted only to key employees, including
officers or directors who are employees of the Company, and are exercisable
immediately or in installments following a period of two (2) years after grant
but within ten (10) years from the date of grant (five (5) years in the case of
options granted to holders of more than 10% of the Company's voting stock). The
exercise price must be at least equal to the fair market value of the Company's
Common Stock on the date granted (110% in the case of 10% shareholders). At
December 31, 1997, Incentive Stock Options for an aggregate of 536,920 shares of
Common Stock at exercise prices ranging from $.74 to $1.28 were outstanding.

      Non-Qualified Stock Options may be granted under the Plans or otherwise to
officers, directors, consultants and key employees. The exercise price is not
limited and may be below the fair market value of the Company's Common Stock on
the date of grant. At December 31, 1997, Non-Qualified Stock Options for an
aggregate of 692,500 shares of Common Stock at exercise prices ranging from $.74
to $9.00, were outstanding.

      The Company applies the disclosure-only provisions of SFAS 123 "Accounting
for Stock-Based Compensation," continuing to measure compensation cost in
accordance with APB 25 " Accounting for Stock Issued to Employees." Had
compensation cost been determined based on the fair value at the grant date
consistent with the provisions of SFAS 123, the Company's proforma net income
(loss) and earnings per share for the years ended December 31, 1997 and 1996
would have been:

                                                       1997           1996

      The weighted average fair value of each option has been estimated on the
date of grant using the Black-Scholes options pricing model with the following
weighted average assumptions used for grants in 1997 and 1996, respectively; no
dividend yield; expected volatility of 90%; risk-free interest rate (ranging
from 5.00% - 6.61%); and expected lives ranging from approximately 1.5 to 5
years. Weighted averages are used because of varying assumed exercise dates.
