                                  THE COMPANY
 
  Porex is a leading developer, manufacturer and distributor of porous plastic
products and has a 35-year history of innovation and market leadership in the
field of porous plastics. The Company's porous and solid plastic components and
products are used in a wide range of healthcare, consumer and industrial
applications, primarily to filter, wick, diffuse, drain, vent or control the
flow of fluids or gases. For the healthcare industry, Porex designs and
manufactures various components that are incorporated in the products of other
healthcare manufacturers. In addition, the Company produces its own line of
pipette tips, blood serum filters, surgical implants and plastic pharmaceutical
vials. In the consumer products market, Porex designs and manufactures porous
plastic components for use by other manufacturers in a variety of home and
office products and appliances, such as writing pen tips, or "nibs", used in
marking and highlighting pens, home water filters and deodorant and fragrance
applicators. Porex also manufactures a wide range of custom porous plastic
components for industrial applications, including automobile battery vents,
wastewater treatment filters and silencers to reduce sound levels of compressed
air. The Company has a diverse customer base of over 600 customers, including
numerous Fortune 500 companies. In Fiscal 1997, net sales and net income of the
Company were $52.9 million and $8.1 million, respectively. Healthcare, consumer
and industrial applications comprised approximately 51%, 28% and 21%,
respectively, of total net sales.
 
  Porex has established a leading reputation in the porous plastics industry
for developing innovative manufacturing technology and providing solutions to
complex customer requirements. Porex has also developed significant expertise
in combining porous plastic components with injection molded solid plastic
products, which has broadened its range of product offerings. Porex believes
its competitive strengths include technological leadership in the design and
manufacture of porous plastic products; efficient manufacturing operations
based on proprietary, technologically advanced equipment; and an ability to
collaborate with customers to solve complex design and performance
requirements. In addition, Porex has a technically skilled sales and marketing
force and experienced management.
 
  Porex's objective is to increase sales and net income by leveraging its
competitive strengths and broadening its product offerings. To achieve this
objective, the Company intends to (i) continue internal development of new
products and technologies, (ii) acquire businesses with products and
technologies that complement the Company's current product offerings and (iii)
pursue growth opportunities in international markets. Over the last three
fiscal years, the Company's net sales and net income have grown at a compounded
annual rate of 16.9% and 56.6%, respectively.
 
  The Company is a newly formed holding company incorporated in November 1997.
In connection with its formation, the Company issued 15,000,000 shares of
Common Stock to Synetic in exchange for all of the outstanding capital stock of
Porex Technologies Corp. ("PTC"). As a result, the Company owns all the
outstanding capital stock of PTC, through which the Company conducts its
business operations. The Company's principal offices are located at 500

                                 RISK FACTORS
 
  In addition to the other information in this Prospectus, the following
factors should be considered carefully by prospective investors in evaluating
the Company and its business before purchasing shares of Common Stock offered
hereby. Statements contained in this Prospectus regarding the Company's
expectations with respect to its future operations and other information,
which can be identified by the use of forward-looking terminology, such as
"may," "will," "expect," "anticipate," "estimate," "seek" or "continue" or the
negative thereof or other variations thereon or comparable terminology, are
"forward-looking statements" (as such term is defined in the Private
Securities Litigation Reform Act of 1995). Because such statements include
risks and uncertainties, actual results may differ materially from those
expressed or implied by such forward-looking statements. Factors that could
cause actual results to differ materially from those expressed or implied by
such forward-looking statements include, but are not limited to, the factors
set forth in "Risk Factors," "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Business."
 
SUBSTANTIAL CONTROL BY SYNETIC
 
  Immediately prior to the Offerings, Synetic was the owner of all of the
equity of the Company. Upon completion of the Offerings, Synetic will own
approximately 86% of the outstanding Common Stock and will therefore retain
effective control of the Company and will be able to control the vote on
matters submitted to the Company's stockholders and will also be able to elect
the Board of Directors of the Company. In addition, certain directors or
officers of Synetic are also directors or officers of the Company and may have
conflicts of interest with respect to certain transactions that may affect the
Company, such as transactions involving business dealings between the Company
and Synetic, acquisition opportunities, the issuance of additional shares of
Common Stock and other matters involving conflicts which cannot now be
foreseen. The Company's Certificate of Incorporation provides for the
allocation of certain corporate opportunities between Synetic and the Company.
Officers and directors of Porex also beneficially own shares and have been
granted options to purchase shares of Synetic. See "Description of Capital
Stock--Certain Provisions of the Certificate of Incorporation, By-Laws and
Delaware Law" and "Security Ownership of Management."
 
  The level of ownership of the outstanding Common Stock by Synetic may have
the effect of discouraging or making more difficult, absent the support of
Synetic, a proxy contest, a merger involving the Company, a tender offer, an
open-market purchase program or other purchases of Common Stock that could
give stockholders of the Company the opportunity to realize a premium over the
then-prevailing market price of their shares of Common Stock. See
"Transactions and Relationship with Principal Stockholder."
 
IMPLEMENTATION OF GROWTH STRATEGY; INTEGRATION OF ACQUISITIONS
 
  The Company has achieved significant growth in net sales and net income
during the past several years and has implemented a strategy to continue this
growth. No assurance can be given that this growth strategy will succeed or
that the Company will be able to maintain its recent rate of growth. The
success of the Company's growth strategy will depend to a substantial degree
on its ability to internally develop new products and technologies, acquire
businesses with complementary products and technologies and pursue growth
opportunities in international markets. Due to the uncertainties inherent in
the development of new products and technologies, there can be no assurance
that the Company will be able to develop new products and technologies or that
such products and technologies will be successful. In addition, there can be
no assurance that the Company will be able to identify and consummate suitable
acquisitions, to obtain the necessary financing on suitable terms for any
future acquisitions, or to effectively and profitably integrate into the
Company any operations that are acquired. Failure to integrate newly acquired
businesses and products may have a material adverse effect on the Company's
operating results and on the market price of the Company's Common Stock. The
Company's ability to manage growth will require significant management
attention and will require it to continue to implement and improve its
operational, financial and management information systems and to motivate and
effectively manage an increasing number of employees. Failure to manage such
growth effectively could materially adversely affect the Company's business,
financial condition or results of operations. In addition, international
acquisitions may create additional risks, including those relating to
political, economic and regulatory matters. See "Business--Growth Strategy."

POTENTIAL PRODUCT LIABILITY RISK AND ADEQUACY OF INSURANCE COVERAGE
 
  The products sold by the Company expose it to potential risk for product
liability claims or recalls. Certain of the Company's products are designed to
be implanted in the human body for long periods of time. Design defects and
manufacturing defects with respect to such products sold by the Company could
result in product liability claims and/or a recall of one or more of the
Company's products. In addition, in recent years, there has been an increased
public interest in product liability claims for implanted medical devices. The
claims may be brought by individuals seeking relief for themselves or,
increasingly, by groups seeking to represent a class. The Company believes
that it carries adequate insurance coverage against product liability claims
and other risks. There can be no assurance, however, that claims in excess of
Porex's insurance coverage will not arise in connection with the development,
manufacture or sale of its products. In addition, Porex's insurance policies
must be renewed annually. Although Porex has in the past been able to obtain
adequate insurance coverage at an acceptable cost and believes that it is
adequately indemnified for products manufactured by others and distributed by
it, there can be no assurance that in the future it will be able to obtain
such insurance at an acceptable cost, or at all, or be adequately protected by
such indemnification. A successful claim or claims brought against the Company
in excess of available insurance coverage and not covered by adequate
indemnities could have a material adverse effect on the business, financial
condition or results of operations of the Company. Moreover, product liability
claims or product recalls in the future could, regardless of their outcome,
have a material adverse effect on the Company's reputation and on its ability
to obtain and retain customers for its products. See "--Certain Litigation"
and "Business--Potential Liability Risk and Availability of Insurance."
 
CERTAIN LITIGATION
 
  From Fiscal 1988 through Fiscal 1990, Porex distributed silicone mammary
implants ("implants") in the United States pursuant to a distribution
arrangement (the "Distribution Agreement") with a Japanese manufacturer (the
"Manufacturer"). Because of costs associated with increased government
regulation and examination, Porex's supplier determined to withdraw its
implants from the United States market. On July 9, 1991, the FDA mandated a
recall of all implants manufactured by companies that elected not to comply
with certain FDA regulations regarding data collection. Accordingly, Porex
notified all of its customers not to use any implants sold by Porex and to
return such implants to Porex for a full refund. Porex believes that after
accounting for implants returned to it, the aggregate number of recipients of
implants distributed by Porex under the Distribution Agreement in the United
States totaled approximately 2,500.
 
  Since March 1991, Porex has been named as one of many co-defendants in a
number of actions brought by recipients of implants. Certain of the actions
against Porex have been dismissed where it was determined that the implant in
question was not distributed by Porex. In addition, as of November 5, 1997, 61
claims have been settled on a favorable basis by the Manufacturer, or by the
insurance carriers of Porex, without material cost to Porex. As of November 5,
1997, 228 actions and 32 out-of-court claims were pending against Porex. One
of the pending federal actions, Donna L. Turner v. Porex Technologies
Corporation, et al., is styled as a class action. Of the 228 actions, 111
involve implants identified as distributed by Porex and 84 cases involve
implants identified as not having been distributed by Porex. In the remaining
33 actions, the distributors of such implants have not been identified. The
number of claims made by individuals during Fiscal 1997 was similar to the
number of claims made during Fiscal 1996, both of which were significantly
lower than the number of claims made during Fiscal 1995.
 
  The typical case or claim alleges that the individual's mammary implants
caused one or more of a wide range of ailments. These implant cases and claims
generally raise difficult and complex factual and legal issues and are subject
to many uncertainties and complexities, including, but not limited to, the
facts and circumstances of each particular case or claim, the jurisdiction in
which each suit is brought, and differences in applicable law. The Company
does not have sufficient information to evaluate each case and claim.
 
  The Company believes that it has a valid claim for indemnification under the
Distribution Agreement with respect to any liabilities that could result from
pending actions or claims by recipients of implants or any similar actions or
claims that may be commenced in the future. However, Porex's right to
indemnification is subject to a disagreement with the Manufacturer. Pending
the resolution of such disagreement, the Manufacturer has been paying a
portion of the costs of the settled claims.
 
 
                                       8
<PAGE>
 
  In 1994, Porex was notified that its lead primary and excess insurance
carrier would not renew its then-existing insurance coverage after December
31, 1994 with respect to actions and claims arising out of Porex's
distribution of implants. In response, Porex exercised its right under the
policies with its lead carrier to purchase extended reporting period coverage
with respect to such actions and claims. This extended reporting period
coverage provides insurance, subject to existing policy limits but for an
unlimited time period, with respect to actions and claims made after December
31, 1994 that are based on events that occurred during the policy period. In
addition, Porex has similarly purchased extended reporting period coverage
under its other excess insurance policies, all of which coverage will by its
terms expire by December 31, 1997 and Porex expects to purchase further
extended reporting period coverage from excess insurers to the extent such
coverage is reasonably available. The Company believes that its present
coverage, together with its insurance policies in effect on or before December
31, 1994, should provide adequate coverage against liabilities that could
result from actions or claims arising out of Porex's distribution of implants.
To the extent that certain of such actions and claims seek punitive and
compensatory damages arising out of alleged intentional torts, such damages,
if awarded, may or may not be covered, in whole or in part, by Porex's
insurance policies. In addition, Porex's recovery from its insurance carriers
is subject to policy limits and certain other conditions. Porex has been
expensing the retention amount under its policies as incurred.
 
  Although no assurances can be given, the Company believes that none of the
claims relating to the above-mentioned proceedings will have a material
adverse effect on the financial condition or results of operations of the
Company. See "Business--Litigation."
 
REGULATORY REQUIREMENTS
 
  Porex manufactures and distributes certain medical/surgical devices,
including plastic and reconstructive surgical implants. The development,
testing, marketing and manufacturing of such devices are regulated under the
Medical Device Amendments of 1976 to the Federal Food, Drug and Cosmetic Act
(the "1976 Amendments") and additional regulations promulgated by the Food and
Drug Administration (the "FDA"). In general, these statutes and regulations
require that manufacturers adhere to certain standards designed to ensure the
safety and effectiveness of medical devices. Compliance with such requirements
and the process of obtaining approvals can be costly, complicated and time-
consuming and there can be no assurance that such approvals will be granted on
a timely basis, or at all.
 
  Under the 1976 Amendments, each medical device manufacturer must be
registered and must comply with intricate regulations. The FDA is authorized
to obtain and inspect devices, their labeling and advertising, and to inspect
the facilities in which they are manufactured. A device is classified as a
Class I, II or III, depending on the degree of regulation deemed appropriate
and necessary. Class I devices are subject only to general controls. Class II
devices, in addition to general controls, are subject to performance
standards. Class III devices, including most devices used or implanted in the
body, require FDA pre-market approval before they may be marketed.
 
  Products which Porex may introduce in the future will be subject to the FDA
classification requirements. The process may involve clinical investigation,
or human study, to generate data to prove safety and effectiveness. There can
be no assurance that new products will be approved, or that they will be
classified in the manner requested by Porex. Classification can be an
expensive and time consuming process that can delay or prevent the
introduction of products.
 
  Medical devices also are subject to postmarket reporting requirements when
the device may have caused or contributed to the death or serious injury, and
when device malfunctions would be likely to cause or contribute to a death or
serious injury. If safety or efficacy problems occur after the product reaches
the market, the FDA may take steps to prevent or limit further marketing of
the product. Additionally, the FDA actively enforces regulations prohibiting
marketing of devices for indications or uses that have not been cleared or
approved by the FDA. See "Business--Regulation."

DEPENDENCE ON PROPRIETARY RIGHTS AND PROPRIETARY KNOW-HOW
 
  The Company depends in part on its proprietary technology and technical
know-how. The Company relies on a combination of trade secret, patent and
other intellectual property laws and confidentiality procedures and non-
disclosure contractual provisions to protect its intellectual property.
However, any such method may not provide adequate protection, and such
information may become known to, or be independently developed by, competitors
and the Company's patent or proprietary rights in such knowledge may be
challenged. Such events could have a material adverse effect on the Company's
business, financial condition or results of operations. See "Business--
Intellectual Property."
 
CHANGING CUSTOMER REQUIREMENTS
 
  The Company's products are integrated into end products used in various
industries, some of which are characterized by rapidly changing technology and
frequent new product introductions. Accordingly, the Company's success will
depend to a substantial degree on its ability to develop and introduce in a
timely manner products and applications that meet changing customer
requirements. However, there can be no assurance that the Company will be able
to do so. See "--Competition."
 
COMPETITION
 
  The Company competes with other producers of porous plastic materials, as
well as producers of non-plastic porous materials used instead of porous
plastic in certain applications. The Company's ongoing success requires the
continued development of new products and applications of its existing
products. The Company's competitors may succeed in developing porous plastic
and other products that are more effective than the Company's products. See
"Business--Competition."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
  Upon consummation of the Offerings, the Company will have a total of
17,500,000 shares of Common Stock (17,875,000 if the Underwriters over-
allotment options are exercised in full) outstanding and approximately
          shares of Common Stock subject to stock options granted under the
Company's Stock Option Plans. See "Management--Compensation Pursuant to Plans
and Arrangements of the Company." Of such shares, 2,500,000 shares of Common
Stock (2,875,000 if the Underwriters over-allotment options are exercised in
full) being sold in the Offerings (together with any shares sold upon exercise
of the Underwriters' over-allotment option) will be immediately eligible for
sale in the public market without restriction, except for shares purchased by
or issued to any "affiliate" of the Company (within the meaning of the
Securities Act of 1933, as amended (the "Securities Act")). All of the
outstanding shares of Common Stock held by Synetic will be "restricted
securities" as such term is defined under Rule 144 under the Securities Act
("Rule 144"). The Company and Synetic have agreed not to sell or otherwise
dispose of any shares of Common Stock without the consent of Merrill Lynch for
a period of 180 days after the date of this Prospectus, subject to certain
exceptions. See "Shares Eligible for Future Sale" and "Underwriting."
 
  Subject to the restrictions described above and applicable law, Synetic will
be free to sell shares of Common Stock it owns upon completion of the
Offerings. Upon consummation of the Offerings, Synetic will own 86% (84% if
the Underwriters over-allotment options are exercised in full) of the
outstanding Common Stock. In connection with the Offerings, the Company and
Synetic have entered into an agreement which provides that Synetic will have
certain rights to have the shares of Common Stock owned by it after the
Offerings registered by the Company under the Securities Act in order to
permit the public sale of such shares. While Synetic in the future may effect
sales of Common Stock that will reduce its ownership interest in the Company,
Synetic has advised the Company that it currently has no plans to reduce its
ownership interest in the Company through sales or other dispositions
following the Offerings. However, Synetic is not subject to any contractual
obligation to retain its controlling interest, except that Synetic has agreed
not to sell or otherwise dispose of any shares of the Company for a period of
180 days after the date of the Prospectus, as noted above. No prediction can
be made
 
                                      10
<PAGE>
 
as to the effect, if any, that future sales of Common Stock by Synetic, or the
availability of Common Stock for future sale, will have on the market price of
the Common Stock prevailing from time to time. Sales of substantial amounts of
Common Stock (including shares issuable upon the exercise of stock options),
or the perception that such sales could occur, could materially and adversely
affect prevailing market prices for the Common Stock and the ability of the
Company to raise equity capital in the future. In addition, in the event the
Company makes future acquisitions, the Company may issue equity securities as
consideration for one or more such acquisitions or may be required to raise
funds in addition to those being raised in the Offerings through borrowings or
the issuances of additional debt or equity securities. See "--Implementation
of Growth Strategy; Integration of Acquisitions," "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Capital Resources
and Liquidity," "Business--Growth Strategy," "Transactions and Relationship
with Principal Stockholder--Certain Agreements" and "Shares Eligible for
Future Sale."
 
ABSENCE OF PUBLIC MARKET FOR SECURITIES
 
  Prior to these Offerings there has been no public market for any securities
of the Company. Although the Company intends to make application to quote the
Common Stock on the Nasdaq National Market, there can be no assurance that any
trading market for the shares will develop, or, if any such market develops,
that it will be sustained. Accordingly, purchasers of the Common Stock may
experience difficulty selling or otherwise disposing of such shares. The
initial public offering price of the Common Stock offered hereby has been
determined through negotiations among the Company and the Underwriters and may
not be indicative of the market price of the Common Stock after the Offerings.
Moreover, the market price of the Common Stock after the Offerings may be
volatile and will be affected by, among other things, the Company's
performance, industry related factors and general market conditions. See
"Underwriting" for information relating to the method for determining the
initial public offering price of the Common Stock.
 
DILUTION; ABSENCE OF DIVIDENDS
 
  Purchasers of the Common Stock offered hereby will experience immediate and
substantial dilution. See "Dilution." The Company currently anticipates that
it will retain all available funds for use in its business and does not expect
to pay any cash dividends in the foreseeable future. See "Dividend Policy."

<PAGE>
 
                                USE OF PROCEEDS
 
  The net proceeds to be received by the Company from the issuance and sale of
Common Stock offered hereby assuming an estimated initial public offering
price of $     per share are estimated to be $     ($     if the Underwriters'
over-allotment option is exercised) after deducting underwriting discounts and
commissions and estimated offering expenses payable by the Company. The
Company currently intends to use the funds for general corporate purposes,
which may include acquisitions. As part of its growth strategy, the Company
reviews acquisition opportunities on a regular basis and from time to time
enters into negotiations with respect to potential acquisitions. As of the
date of this Prospectus, the Company has no agreement or understanding with a
prospective acquisition candidate in respect of a specific transaction. There
can be no assurance that the Company will be able to consummate any
acquisitions. See "Risk Factors--Implementation of Growth Strategy;
Integration of Acquisitions" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital
Resources."
 
  Pending use of the net proceeds of the Offerings, the Company intends to
invest such proceeds in U.S. government or investment-grade marketable
securities.
 
                                DIVIDEND POLICY
 
  The Company currently intends to retain any earnings to finance the
development and expansion of the Company's business and does not anticipate
paying any cash dividends in the foreseeable future. The declaration and
payment of dividends by the Company are subject to the discretion of the Board
of Directors of the Company. Any future determination to pay dividends will
depend on the Company's results of operations, financial condition, capital
requirements, contractual restrictions and other factors deemed relevant at
the time by the Board of Directors. See "Risk Factors--Dilution; Absence of
Dividends."

                                   DILUTION
 
  At September 30, 1997, the Company had a net tangible book value of $34.7
million or $2.31 per share of Common Stock. Net tangible book value represents
the difference between the tangible assets of the Company and the total
liabilities of the Company. Net tangible book value per share of Common Stock
represents the total net tangible book value of the Company divided by the
number of shares of Common Stock outstanding.
 
  After giving effect to the sale by the Company of the shares to be sold in
the Offerings and the receipt of the estimated net proceeds thereof, after
deducting underwriting discount and estimated offering expenses payable by the
Company, the net tangible book value of the Company would have been $    per
share at September 30, 1997. This amount represents an immediate increase in
net tangible book value per share of $    to Synetic and an immediate dilution
in net tangible book value per share (the difference between the public
offering price of the shares and the net tangible book value after the
offering) of $    to the persons purchasing such shares at the public offering
price. The following table illustrates such per share dilution:

  The following table sets forth the unaudited capitalization of the Company
at September 30, 1997 and as adjusted to give effect to the sale in the
Offerings of 2,500,000 shares of Common Stock at the assumed public offering

THREE MONTHS ENDED SEPTEMBER 30, 1996 COMPARED TO THREE MONTHS ENDED SEPTEMBER
30, 1997
 
  Net sales for the first quarter of Fiscal 1998 increased 32.6% to
$14,833,000 from $11,185,000 in the comparable prior year period. The
acquisition of Interflo in February 1997 accounted for $1,611,000 of the
increase in sales. The balance of the increase in net sales was due
principally to (a) significant increased sales of writing instrument nibs, (b)
increased sales to medical original equipment manufacturers ("OEMs") of porous
components used in diagnostic products and (c) increased sales of porous
plastic components to the industrial market, including components used in
electronic devices.
 
  Cost of sales for the first quarter of Fiscal 1998 increased 35.7% to
$8,316,000 from $6,126,000 in the comparable prior year period. This increase
was attributable to the operations of Interflo, the increased sales volume
noted above and to a lesser extent additional depreciation for equipment
associated with process improvements. As a percent of net sales, cost of sales
for the first quarter of Fiscal 1998 increased to 56.1% from 54.8% in the
prior year period due to certain higher costs associated with the operations
of Interflo. The Company expects to improve the productivity of Interflo
through the introduction of the Company's proprietary technology and
manufacturing processes.
 
  Selling, general and administrative expenses for the first quarter of Fiscal
1998 increased 15.5% to $3,189,000 from $2,762,000 in the comparable prior
year period. This increase was due primarily to an increase in expenses
associated with the increase in sales volume noted above and to the operations
of Interflo. As a percent of net sales, selling, general and administrative
expenses for the first quarter of Fiscal 1998 decreased to 21.5% from 24.7% in
the prior year. This improvement reflects the higher growth rate of net sales
as compared to the growth rate of selling, general and administrative
expenses, a portion of which are fixed in nature and do not increase
proportionately with net sales.
 
                                      16
<PAGE>
 
  Other income, net, which is comprised primarily of interest income, for the
first quarter of Fiscal 1998 decreased 66.2% to $103,000 from $305,000 from
the prior year period due to reduced cash available for investment following
the payment in cash of the purchase price for the acquisition of Interflo.
 
  The effective tax rate for the first quarter of Fiscal 1998 increased to
39.7% from 37.9% in the prior year period due primarily to foreign tax
adjustments lowering the effective rate in the prior year.
 
FISCAL 1997 COMPARED TO FISCAL 1996
 
  Net sales for Fiscal 1997 increased 17.2% to $52,885,000 from $45,129,000 in
the comparable prior year period. The acquisition of Interflo and other
businesses accounted for $4,102,000 of the sales increase. The balance of the
increase in net sales was due principally to (a) increased sales of writing
instrument nibs primarily as a result of the introduction of a new line of
writing instrument products, (b) increased sales of medical OEM porous
components, such as pipette tip filters, and sales of the Company's own
finished products, such as pipette tips, primarily to the research and
laboratory markets and (c) to a lesser extent, increased sales of surgical
products.
 
  Costs of sales for Fiscal 1997 increased 15.6% to $29,035,000 from
$25,106,000 in the comparable prior year period due to the increased sales
volume noted above and to the operations of Interflo. As a percent of net
sales, cost of sales for Fiscal 1997 decreased to 54.9% from 55.6% in the
comparable prior year period principally due to increased leverage of certain
fixed costs which do not increase proportionately with sales and improvements
in material and labor usage.
 
  Selling, general and administrative expenses for Fiscal 1997 increased 9.2%
to $11,697,000 from $10,714,000 in the comparable prior year period due
primarily to an increase in expenses associated with the increase in sales
volume noted above. As a percent of net sales, selling, general and
administrative expenses for Fiscal 1997 decreased to 22.1% from 23.8% in the
comparable prior year period. This improvement reflects the higher growth rate
of net sales as compared to the growth rate of selling, general and
administrative expenses, a portion of which are fixed in nature and do not
increase proportionately with net sales.
 
  Other income for Fiscal 1997 increased 54.3% to $904,000 from $586,000 in
the comparable prior year period primarily as a result of the investment of
additional cash generated from operations.
 
  The effective tax rate for Fiscal 1997 decreased to 37.9% from 38.8% in the
prior year period primarily as a result of a reduction in state income taxes
resulting from changes in certain state apportionment rules.
 
FISCAL 1996 COMPARED TO FISCAL 1995
 
  Net sales for Fiscal 1996 increased 15.2% to $45,129,000 from $39,180,000 in
the comparable prior year period. The increase in net sales was due
principally to (a) increased sales of medical OEM porous components primarily
used in diagnostic applications and pipette tip filters for the research and
laboratory markets, (b) increased sales of plastic pharmaceutical vials and
(c) increased sales of writing instrument nibs.
 
  Cost of sales for Fiscal 1996 increased 9.1% to $25,106,000 from $23,006,000
in the comparable year period due to the increased sales volume noted above
and additional depreciation related to capital equipment added to expand
production capabilities and improve efficiencies and product development
costs. As a percent of net sales, cost of sales for Fiscal 1996 decreased to
55.6% from 58.7% in the comparable prior year period principally due to
increased leverage of certain fixed costs which do not increase
proportionately with sales and improvements in material and labor usage.
 
  Selling, general and administrative expenses for Fiscal 1996 increased 7.9%
to $10,714,000 from $9,933,000 in the comparable prior year period due
primarily to an increase in expenses associated with the increase in sales
volume noted above. As a percent of net sales, selling, general and
administrative expenses for Fiscal 1996 decreased to 23.8% from 25.4% in the
prior year. This improvement reflects the higher growth rate of net sales as
compared to the growth rate of selling, general and administrative expenses, a
portion of which are fixed in nature and do not increase proportionately with
net sales.

<PAGE>
 
  Other income, which is comprised primarily of interest income for Fiscal
1996 increased 140.2% to $586,000 from $244,000 in the comparable prior year
period primarily as a result of the investment of additional cash generated
from operations.
 
  The effective tax rate for Fiscal 1996 decreased to 38.8% from 41.8% in the
prior year period primarily due to tax credits on certain foreign investments.
 
CAPITAL RESOURCES AND LIQUIDITY
 
  As of September 30, 1997, the Company had $7,352,000 of cash and cash
equivalents. Cash and cash equivalents decreased $5,576,000 in Fiscal 1997 as
a result of (a) net cash used for investing activities of $17,888,000 offset
partially by (b) net cash provided by operations of $13,324,000. Net cash
provided by operating activities in Fiscal 1997 increased 22.5% from
$10,876,000 in Fiscal 1996, principally as a result of increased net income
and increased depreciation and amortization. Net cash used for investing
activities of $17,888,000 in Fiscal 1997 consisted of $12,813,000 paid for
acquired businesses (principally, Interflo) and capital expenditures of
$5,075,000. As of September 30, 1997, the Company had no long-term
indebtedness.
 
  Prior to the Offerings, the Company has operated as a wholly owned
subsidiary of Synetic. As a result, Synetic employees have performed certain
functions on behalf of the Company relating primarily to financial analysis
and tax and legal advice in connection with the Company's operations and other
technical services. Costs associated with these services historically have not
been material. Following the Offerings, as a result of becoming a separate
public company, the Company anticipates that overhead expenses will increase
as a result of (a) the costs associated with being a public company and (b)
costs relating to the addition of any personnel required to manage and
administer its affairs and to pursue its growth strategy. The Company at this
time cannot estimate the magnitude of the increase in overhead expenses. While
no assurance can be given, the Company believes that any such incremental
costs will not be material.
 
  As part of its growth strategy, the Company reviews acquisition
opportunities on a regular basis and from time to time enters into
negotiations with respect to potential acquisitions. Since the Company's
working capital requirements have generally been met by cash flow from
operations and no material commitments for capital expenditures exist, the
Company intends to use the net proceeds of the Offerings for general corporate
purposes, including potential acquisitions. Financing for such acquisitions
may also come from several other sources, including, without limitation, (a)
proceeds from the incurrence of indebtedness or the issuance of common stock,
preferred stock, convertible debt or other securities and (b) borrowings from
Synetic. As consideration for any acquisitions, in addition to cash, the
Company may issue securities such as notes or common or preferred stock. There
can be no assurance that the Company's acquisition program will be successful.
See "Risk Factors--Implementation of Growth Strategy; Integration of
Acquisitions," "Use of Proceeds" and "Business--Growth Strategy."

                        PRO FORMA FINANCIAL INFORMATION
 
  The Unaudited Pro Forma Condensed Consolidated Statement of Income for
Fiscal 1997 has been prepared by the Company by combining, with the
adjustments described in the accompanying notes, the results of operations of
the Company and Interflo assuming the acquisition of Interflo had been
consummated at July 1, 1996, the beginning of the period presented. The pro
forma information is not necessarily indicative of results of operations which
would have occurred had the acquisition been consummated as of July 1, 1996,
or of the results of future operations.
 
  The results of operations of the Company are derived from the Company's
audited Consolidated Financial Statements for Fiscal 1997. The results of
operations of Interflo are derived from the books and records of Interflo for
the period from July 1, 1996 to February 10, 1997 (date of acquisition). The
pro forma adjustments are based upon available information and certain
assumptions that the Company believes are reasonable.
 
  The Unaudited Pro Forma Condensed Consolidated Statement of Income should be
read in conjunction with the Consolidated Financial Statements of the Company
and the related notes thereto as well as the Financial Statements of Interflo
and the related notes thereto which are included elsewhere in this Prospectus.

                                   BUSINESS
 
GENERAL
 
  Porex is a leading developer, manufacturer and distributor of porous
plastics products and has a 35-year history of innovation and market
leadership in the field of porous plastics. The Company's porous and solid
plastic components and products are used in a wide range of healthcare,
consumer and industrial applications. Porex's principal products are porous
plastic components, which are incorporated by other manufacturers in a wide
array of finished products, and Porex also designs and manufactures its own
line of finished products in the healthcare area. Below is a summary of
Porex's three product areas.
 
  Healthcare. In the healthcare industry, Porex designs and manufactures
various components that are incorporated in the products of other healthcare
manufacturers, as well as its own line of pipette tips, blood serum filters,
surgical implants and plastic pharmaceutical vials. The Company sells its
healthcare components and products directly to customers and through
independent distributors, such as Allegiance Healthcare Corporation and Fisher
Scientific. Healthcare products represented approximately $27.2 million, or
51%, of the Company's net sales for Fiscal 1997.
 
  Consumer. Porex manufactures porous plastic components for use by other
manufacturers in a variety of home and office products and appliances, such as
writing pen tips, or "nibs", used in marking and highlighting pens, home water
filters, and deodorant and fragrance applicators. Sales to this market
represented approximately $14.7 million, or 28%, of Porex's net sales for
Fiscal 1997.
 
  Industrial. Porex manufactures a wide range of custom porous plastic
components for industrial applications, including automobile battery vents,
wastewater treatment filters and silencers to reduce sound levels produced by
compressed air. Industrial products represented approximately $11.0 million,
or 21%, of Porex's net sales for Fiscal 1997.
 
  The Company's porous plastic products are used to filter, wick, diffuse,
drain, vent or control the flow of fluids or gases. Porous plastic has a
permeable structure with omni-directional, interconnecting pores that allow
fluids and gases to flow in all directions. In numerous healthcare, consumer
and industrial applications, porous plastic is a cost-effective and high-
quality alternative to other non-porous plastic media. Depending on the
intended application, the Company manufactures porous plastic products with
pore sizes between approximately 5 and 500 micrometers (one micrometer is
equal to one-millionth of a meter; an object of 40 micrometers in size is
about as small as can be discerned by the naked eye). Porex manufactures
porous plastic materials at its own facilities as fabricated devices, custom-
molded shapes, sheets, tubes or rods, depending on the intended application or
customer specifications.
 
  The table below sets forth the aggregate amount of net sales of the
Company's products for healthcare, consumer and industrial applications. See
Note 5 to the Company's Consolidated Financial Statements for Segment
Information by geographic area.

COMPETITIVE STRENGTHS
 
  Porex's leading reputation for developing innovative manufacturing
technology and providing solutions to complex customer requirements results
from its competitive strengths described below.
 
  Technological Leadership. The Company is a technological leader in the
design and manufacture of porous plastic products. Through 35 years of
experience, the Company has developed extensive proprietary technologies that
the Company believes provide it with significant competitive advantages. One
such advantage is the proprietary design of its molding machines and molds,
which provide an efficient and cost-effective method of manufacturing high-
quality products.
 
  Advanced, Efficient Manufacturing Capabilities. The Company has
technologically advanced manufacturing capabilities, with four manufacturing
facilities located in the United States and additional facilities in the
United Kingdom and Germany. The Company has spent over $12.0 million in the
last three fiscal years on new machines and technology to improve efficiency
and manufacturing processes in order to produce higher quality products. Two
of the Company's U.S. facilities operate under Good Manufacturing Practices
("GMP") protocols and are registered with the FDA and a third U.S. facility
will seek FDA registration. Both of the Company's European facilities are
International Standards Organization ("ISO") certified. The Company believes
that its operation under GMP protocols and ISO certification and its
recognition as a reliable source of supply gives it significant competitive
advantages in the United States and Europe.
 
  Active Collaboration with Customers. Since its inception, Porex has
dedicated itself to identifying and implementing solutions to complex customer
design and performance requirements. The Company's customer-focused teams
consult with customers and take a proactive role in developing new
applications of its proprietary technology. The Company has a diverse customer
base of over 600 customers, including numerous Fortune 500 companies.
 
  Technically Skilled Sales Force. The Company's marketing activities are
conducted by a sales and marketing force of 19 professionals with in-depth
knowledge of plastics technologies and product applications. This knowledge
enables them to identify and develop products that provide solutions to both
industry-wide and customer-specific problems. The Company believes that the
technical skills of its sales force have created close working relationships
with many of its customers, allowing the Company to respond promptly to
customer demands.
 
  Experienced Management. The Company's senior managers responsible for
manufacturing, research and development, and sales and marketing have played
an integral role in the development of the porous plastics industry. Several
of these managers have more than 20 years of industry experience and have been
important to the Company's identification of emerging customer needs, the
development of new applications for its core technologies and the
establishment of its proprietary manufacturing facilities and processes.
 
GROWTH STRATEGY
 
  The Company's objective is to increase sales and net income by leveraging
the Company's competitive strengths and broadening its product offerings. To
achieve this objective, the Company intends to internally develop and acquire
new products and technologies that complement the Company's current product
offerings. In addition, the Company intends to pursue growth opportunities in
international markets.
 
  Internal Development and Acquisition of Complementary Products and
Technologies. The Company believes there are significant opportunities for new
applications of porous plastic products and components. In addition, the
Company intends to expand its product offerings to include non-plastic porous
products. The Company anticipates pursuing these opportunities by internally
developing and acquiring (i) non-plastic porous
 
                                      22
<PAGE>
 
media products and technologies, (ii) new products and technologies in the
life sciences and clinical products areas to take advantage of its established
distribution network and (iii) new products in the surgical products area.
 
  . New Porous Media Products and Technologies. Historically, substantially
    all of the Company's porous plastic components and products have been
    manufactured from thermoplastic polymers. The Company believes, however,
    that certain non-plastic porous media, such as fiber, felts and
    membranes, are preferred by certain customers over porous plastics for
    certain applications. The Company is seeking to increase sales to
    existing customers and gain new customers by expanding its product lines
    to include non-plastic porous media through internal development and
    acquisitions. The Company believes that there are many attractive
    acquisition candidates with different porous media technology that are
    privately held companies with fewer resources and customer relationships
    than Porex. By acquiring one or more of these companies, the Company
    believes that it can penetrate the market for non-plastic porous media
    products through leveraging its own size, manufacturing experience and
    reputation for providing innovative customer-driven solutions in the
    porous plastics area.
 
  . Life Sciences and Clinical Products. Porex believes that it can achieve
    sales growth in the life sciences and clinical products areas by
    acquiring businesses with new products and technologies and through
    internal development of new products. By broadening its mix of life
    sciences and clinical products, Porex believes that it can increase sales
    to medical and laboratory product distributors by taking advantage of the
    industry trend to consolidate the sources of supply. Porex currently
    distributes its life sciences and clinical products through distributors
    such as Allegiance Healthcare Corporation and Fisher Scientific. Porex is
    a "Best Value" supplier partner of Allegiance Healthcare Corporation and
    a key "Outstanding Quality" supplier of Fisher Scientific.
 
  . Surgical Products. Porex has developed strong relationships with plastic
    and reconstructive surgeons through the development and commercialization
    of its MEDPOR surgical implant product line. Through its established
    distribution network, Porex also sells surgical drains and markers. Porex
    intends to expand its product offerings in the surgical products area by
    leveraging its existing relationships with surgeons and its distribution
    network, as well as by acquiring businesses with complementary surgical
    products.
 
  Expansion in International Markets. The Company believes that markets
outside of the United States offer significant growth opportunities for
numerous porous plastic applications that have been proven effective in the
United States. The Company's strategy is to introduce in these markets porous
plastic alternatives to higher-cost or lower-performing products made from
other media. During Fiscal 1997, the Company acquired two U.K. entities,
Sintair and Warwicker, to complement its existing European manufacturing base
and accelerate its growth in Europe. The Company believes its presence in
Europe enables it to work more closely with its customers and gives its
customers assurance of a reliable regional supplier of porous plastic
components. In addition, the Company has a regional office based in Malaysia
to service Pacific Rim customers. This office coordinates marketing of the
Company's porous plastic components through independent sales representatives
in several Asian countries. The Company intends to aggressively seek further
opportunities to increase its sales to foreign customers and its presence in
foreign markets, including expanding its foreign manufacturing capabilities.
 
  There can be no assurance that the Company can successfully implement its
growth strategy and achieve its objectives. See "Risk Factors--Implementation
of Growth Strategy; Integration of Acquisitions."
 
HEALTHCARE PRODUCTS
 
  Porex manufactures porous plastic components for incorporation into
healthcare products made by OEMs. The Company's proprietary products for life
sciences and clinical applications include blood serum filters, pipette tips
and blood tube closure devices. The Company also manufactures and assembles a
line of medical/surgical products designed primarily for use in plastic and
reconstructive surgery, oculoplastic surgery and oral maxillofacial surgery.
 
                                      23
<PAGE>
 
  OEM Medical Product Components. Porex manufactures various porous plastic
components that it sells to OEMs for incorporation into their finished
products. These porous plastic products are used to filter, wick, diffuse,
drain, vent or control the flow of fluid or gases and are also used as
membrane supports in certain products. The components include (i) self-sealing
valves in surgical vacuum canisters to minimize exposure to blood or other
body fluids and to protect downstream vacuum sources, (ii) a venting system
for catheters which allows air to vent from a catheter as it is inserted into
a vein, while at the same time preventing blood spillage and possible
contamination of hospital personnel, (iii) vents for blood storage containers
used in clinical research, and (iv) an array of porous plastic strips and
similar components used for wicking body fluids in diagnostic testing and
monitoring kits for professional and home use.
 
  Life Sciences and Clinical Products. The Company's life science products
include a full line of pipette tips used by research laboratories worldwide.
The Company produces certain pipette tips that contain patented porous plastic
filters that prevent contamination of pipetters and test samples. In the
clinical area, Porex's blood serum filters are used to separate microscopic
particles and fibrous matter (fibrin) from centrifuged blood serum to prevent
clogging of automated laboratory chemical analysis equipment. Porex also
manufactures a line of closure devices that are used with blood serum filters
and tubes. Porex believes that the demand for its current blood serum filters
has been decreasing in the past few years due to the use of automated blood
testing equipment which does not require filtered blood serum for analysis.
 
  The Company has identified disposable plastic products for the life sciences
and clinical market as a niche market with significant growth opportunity. In
this area, the Company has recently introduced two new products: (i) an
enhanced pipette tip product line for hand and automatic pipetters and (ii) a
line of plastic test tubes. A pipetter is a device for transferring a precise
amount of fluid.
 
  Surgical Products. Porex's surgical products are marketed primarily to
surgeons who specialize in plastic and reconstructive surgery, oculoplastic
surgery and oral maxillofacial surgery. The product line includes MEDPOR
Surgical Implant polymeric biomaterial, used for craniofacial reconstruction
and augmentation, and TLS Surgical Drainage Systems for small surgical
incisions. Porex also markets Squeeze-Mark and TLS Surgical Marker pens to
mark the areas of proposed surgical incision. Porex manufactures MEDPOR
Surgical Implant material and distributes, and in some cases assembles, the
other items in its surgical product line.
 
  Vials and Solid Plastic Components. Porex manufactures and sells a full line
of plastic pharmaceutical vials. Porex also produces close-tolerance solid
plastic components, which use most thermoplastic resins, but primarily
polystyrene, polypropylene and thermoplastic rubber for medical and industrial
applications. Some of these products are custom designed and produced to
satisfy individual customer specifications.
 
CONSUMER PRODUCTS
 
  Porex manufactures a line of porous plastic components used in a variety of
home and office products and appliances.
 
  Writing Instrument Nibs. Porex's consumer products include a variety of
writing pen tips, or "nibs", which Porex supplies to manufacturers of marking
and highlighting pens. The porous nib conducts the ink stored in the pen
barrel to the writing surface by capillary action. Recently, Porex introduced
a line of stamper nibs for incorporation into a new line of childrens'
markers.
 
  Filters. Porex produces a variety of porous plastic filters used in home
water filters and conditioners which remove particles and sediment. The
Company also manufactures filters incorporating activated carbon used to
reduce chlorine levels in drinking water thereby improving its taste and odor.
 
  Health and Beauty Products. Porex also sells its porous plastic components
for use in health and beauty aid products such as deodorant and fragrance
applicators.
 
 
                                      24
<PAGE>
 
INDUSTRIAL PRODUCTS
 
  Porex manufactures a variety of custom porous plastic components for a broad
range of industrial applications. These components are produced as molded
shapes, and in sheets, tubes and rods, and are individually designed to
customer specifications as to size, rigidity, porosity and other needs. In
this market, the Company believes that it is currently the largest producer of
porous plastic vents used in domestic automobile batteries. The Company also
manufactures a porous plastic material used for large filter support media for
wastewater treatment facilities, which permits recycling and reuse of
wastewater. Recently, the Company has developed a new product for one of its
customers that is used in a system to remove odor and color from wastewater.
Porex also produces other industrial components, including (i) filters to
remove particulate matter, oil and water residues from compressed air lines,
(ii) silencers to reduce sound levels produced by compressed air, (iii)
miscellaneous water filters for industrial use, including use in vending
machines, and (iv) products for facilitating the movement of powdered
materials.
 
MARKETING AND DISTRIBUTION
 
  The Company has a diverse customer base of over 600 customers, including
numerous Fortune 500 companies. Porex distributes its life sciences and
clinical products through Allegiance Healthcare Corporation and Fisher
Scientific and other independent distributors. Porex's surgical products are
sold by its sales personnel, as well as through independent dealers and
agents. In the United States, sales of OEM health care products, industrial
products and consumer products are made directly by Porex's marketing staff.
Internationally, these products are sold by Porex's marketing staff and
through independent distributors and agents, who work with Porex's marketing
staff. Export sales, which are made principally to Europe and Asia, consist
primarily of Porex's OEM medical product, industrial product and consumer
product lines. In Fiscal 1995, Porex's foreign and export product sales were
approximately $10,402,000, or 27% of net sales, as compared to approximately
$12,270,000, or 27% of net sales, in Fiscal 1996 and approximately
$14,730,000, or 28% of net sales, in Fiscal 1997. No customer accounted for
more than 10% of Porex's net sales in Fiscal 1996 or Fiscal 1997. See Note 5
to the Company's Consolidated Financial Statements.
 
RESEARCH AND DEVELOPMENT
 
  Porex maintains a continuing development program devoted primarily to porous
materials and their applications and proprietary products for the life
sciences and clinical laboratories. Development activities include designing
new and improved products, either proprietary or for customers' specific
requirements, and new manufacturing processes. See "Risk Factors--
Implementation of Growth Strategy; Integration of Acquisitions." Porex's
development expenditures were approximately $1,490,000, $2,014,000 and
$1,791,000 for Fiscal 1995, Fiscal 1996 and Fiscal 1997, respectively.
 
RAW MATERIALS
 
  The principal raw materials used by Porex in its plastic products business
are a variety of plastic resins which are generally available from a number of
suppliers in adequate quantities to meet Porex's needs. Porex has been able to
obtain adequate supplies of raw materials and believes that sufficient
supplies will be available in the foreseeable future. Porex has no long-term
supply contracts for the purchase of raw materials. Because the primary
resource used in plastic resins is petroleum, the cost and availability of
plastic resins for use in Porex's products varies to a great extent with the
price of petroleum. Porex's inability to acquire sufficient plastic resins at
a reasonable price would affect its ability to maintain its margins in the
short term.
 
  Porex requires high-grade plastic resins with specific properties as raw
materials for certain of its porous plastic products. Accordingly, shipments
of raw materials from suppliers are closely monitored for compliance with
Porex's standards. Although there are various suppliers of high-grade plastic
resins with specific properties and Porex has not experienced any material
difficulty in obtaining adequate supplies of high-grade materials, the
 
                                      25
<PAGE>
 
inability to obtain such high-grade plastic resins, or any raw materials,
could have a material adverse effect on Porex. To ensure the availability of
high-grade plastic resins with specific properties, Porex occasionally
purchases larger quantities of such products than it would otherwise currently
require.
 
  For its solid plastic products, Porex utilizes commercial grade
thermoplastic resins, including polyethylene, polypropylene and polystyrene,
that are readily available from a large number of sources. Porex is not
dependent on any single source of supply and, because of the ready
availability of such materials, does not maintain a significant inventory of
such raw materials.
 
INTELLECTUAL PROPERTY
 
  Porex uses proprietary technology for manufacturing its porous plastic
materials and injection molding technology for manufacturing its solid plastic
products. Porex believes that its non-patented proprietary manufacturing
processes are protected under trade secret, contractual and other intellectual
property rights which do not afford the statutory exclusivity possible for
patented processes. To protect its proprietary technology and maintain high
manufacturing quality and efficiency, the Company designs and manufactures its
porous molding equipment and most of its molds in-house. In certain instances,
however, Porex has sought and intends to continue to seek patents for specific
products and manufacturing processes.
 
  Porex owns a number of patents and trademarks in the United States and other
countries which it deems to be important to its business. The majority of
Porex's patents and patent applications relate to porous plastics and medical
devices. Porex is the exclusive licensee of a patented valve device used in
one model of its blood serum filters, and of a patent on a surgical drain
device. Porex does not consider either license to be material to its business
operations.
 
REGULATION
 
  The developing, testing, marketing and manufacturing of medical devices such
as plastic and reconstructive surgical implants are regulated under the 1976
Amendments and additional regulations promulgated by the FDA. In general,
these statutes and regulations require that manufacturers adhere to certain
standards designed to ensure the safety and effectiveness of medical devices.
Compliance with such requirements and the process of obtaining approvals can
be costly, complicated and time-consuming and there can be no assurance that
such approvals will be granted on a timely basis.
 
  Under the 1976 Amendments, each medical device manufacturer must be a
registered device manufacturer and must comply with regulations applicable
generally to manufacturing practices and clinical investigations involving
humans. The FDA is authorized to obtain and inspect devices, their labeling
and advertising, and to inspect the facilities in which they are manufactured
in order to ensure that a device is not improperly manufactured or labeled.
Porex is registered with the FDA.
 
  In addition, the sale and marketing of specific medical devices are
regulated by the FDA under the 1976 Amendments, which classify medical devices
based upon the degree of regulation deemed appropriate and necessary. A device
is classified as a Class I, II or III device based on recommendations of
advisory panels appointed by the FDA. Class I devices are subject only to
general controls. Class II devices, in addition to general controls, are
subject to performance standards. Class III devices, including most devices
used or implanted in the body, require FDA pre-market approval before they may
be distributed other than in clinical trials.
 
  Porex's MEDPOR Surgical Implants are regulated as Class II medical devices.
Products which Porex may introduce in the future, if any, may also be
classified as Class I, Class II or Class III medical devices. The procedure
for obtaining classification of a new device as a Class I or Class II device
involves the submission of a petition to the FDA. If the FDA determines that
the device is substantially equivalent to a pre-enactment device or a device
subsequently classified in Class I or Class II, then within the applicable
waiting period it will grant
 
                                      26
<PAGE>
 
approval to market the device commercially. If the FDA determines the device
is not substantially equivalent to a pre-enactment device or a device
subsequently classified in Class I or Class II, it is automatically placed
into Class III and will either require reclassification or the submission of
valid scientific evidence to prove the device is safe and effective for human
use. Devices to be implanted will be categorized as Class III unless such
classification is not necessary to ensure their safety and effectiveness. For
new Class III devices, Porex may submit to the FDA an application for an
Investigational Device Exemption ("IDE"). An approved IDE exempts Porex from
certain otherwise applicable FDA regulations and grants approval for a
clinical investigation, or human study, to generate data to prove safety and
effectiveness. In addition, the possibility exists that certain pre-enactment,
or substantially equivalent, devices may be placed into Class III by the FDA.
 
  When a manufacturer believes that sufficient clinical data have been
generated to prove the safety and effectiveness of the device, it may submit a
pre-market approval application ("PMA") to the FDA. The FDA reviews the PMA
and determines whether it is in submittable form and all key elements have
been included. Following acceptance of the PMA, the FDA continues its review
process which includes submission of the PMA to a panel of experts appointed
by the FDA to review the PMA and to recommend appropriate action. The panel
then recommends that the PMA be approved, not approved or approved subject to
conditions. The FDA may act according to the panel's recommendations, or it
may overrule the panel. In approving a PMA, the FDA may require some form of
post-market surveillance or other restrictions.
 
  Medical devices also are subject to postmarket reporting requirements when
the device may have caused or contributed to the death or serious injury, and
when device malfunctions would be likely to cause or contribute to a death or
serious injury. If safety or efficacy problems occur after the product reaches
the market, the FDA may take steps to prevent or limit further marketing of
the product. Additionally, the FDA actively enforces regulations prohibiting
marketing of devices for indications or uses that have not been cleared or
approved by the FDA. See "Business--Regulation."
 
  Vials that are used to contain and transport pharmaceuticals are not
directly regulated by the FDA. The U.S. Pharmacopeia specifies tests and
properties that are necessary to maintain the potency and pharmacological
properties of the medicine the vial is to be used for. The U.S. Consumer
Product Safety Commission specifies the tests that a vial must pass to be
considered child resistant and senior adult user-friendly. Porex's vials have
been designed to meet such standards.
 
  Certain environmental regulations also apply to Porex's business, and the
Company believes that Porex is in substantial compliance with all of such
regulations. However, Porex is subject to random and scheduled checks by
environmental authorities. The Company does not anticipate that any material
capital expenditures will be required to comply with environmental
regulations. See "Risk Factors--Regulatory Requirements."
 
COMPETITION
 
  The Company competes with other producers of porous plastic materials, as
well as producers of non-plastic porous materials used instead of porous
plastic in certain applications. The Company's ongoing success requires the
continued development of new products and applications of its existing
products. The Company's competitors may succeed in developing porous plastic
and other products that are more effective than the Company's products. In the
porous plastic business, Porex has three competitors in the United States and
two competitors in Europe. The Company's finished products, including surgical
drains and markers, compete with products of a variety of other manufacturers.
 
  The Company attempts to compete principally through product performance,
quality and service, rather than price. The Company believes Porex's principal
competitive strengths are its technological leadership, modern and efficient
manufacturing capabilities, customer relationships and focus, technically
skilled sales force and experienced management. See "--Competitive Strengths."

EMPLOYEES
 
  As of September 30, 1997, the Company had approximately 600 employees.
Approximately 100 production employees at the New York facility of the Company
are covered by a collective bargaining agreement. There are no other
collective bargaining agreements in effect at the Company. The Company
considers its relations with its employees to be good.
 
FACILITIES
 
  The Company has technologically advanced manufacturing capabilities which it
believes are one of its competitive strengths. See "--Competitive Strengths."
The Company's facilities enable it to produce a broad range of high quality
products. The following table sets forth the Company's facilities.

(1) Does not include two additional five-year periods, at the Company's
    option.
 
  All of the Company's facilities are used for manufacturing, office space and
warehouse purposes. The Company believes its facilities and equipment are well
maintained, in good operating condition and, in general, suitable for the
Company's purposes and adequate for its present operation.
 
POTENTIAL LIABILITY RISK AND AVAILABILITY OF INSURANCE
 
  The products sold by Porex expose it to potential risk of product liability
claims, particularly with respect to Porex's life sciences, clinical and
surgical products. The Company believes that it carries adequate insurance
coverage against product liability claims and other risks. There can be no
assurance, however, that claims in excess of Porex's insurance coverage will
not arise. In addition, Porex's insurance policies must be renewed annually.
Although Porex has been able to obtain adequate insurance coverages at an
acceptable cost in the past and seeks indemnification for products
manufactured by others that it distributes, there can be no assurance that in
the future it will be able to obtain such insurance at an acceptable cost, or
at all, or that it will be adequately protected by such indemnification. See
"--Health Care Products," "Risk Factors--Potential Product Liability Risk and
Adequacy of Insurance Coverage" and "Risk Factors--Certain Litigation."
 
LITIGATION
 
  From Fiscal 1988 through Fiscal 1990, Porex distributed implants in the
United States pursuant to the Distribution Agreement with the Manufacturer.
Because of costs associated with increased government regulation and
examination, Porex's supplier determined to withdraw its implants from the
United States market. On July 9, 1991, the FDA mandated a recall of all
implants manufactured by companies that elected not to comply with certain FDA
regulations regarding data collection. Accordingly, Porex notified all of its
customers not to use any implants sold by Porex and to return such implants to
Porex for a full refund. Porex believes that after accounting for implants
returned to it, the aggregate number of recipients of implants distributed by
Porex under the Distribution Agreement in the United States totaled
approximately 2,500.
 
  Since March 1991, Porex has been named as one of many co-defendants in a
number of actions brought by recipients of implants. Certain of the actions
against Porex have been dismissed where it was determined that the
 
                                      28
<PAGE>
 
implant in question was not distributed by Porex. In addition, as of September
10, 1997, 61 claims have been settled on a favorable basis by the
Manufacturer, or by the insurance carriers of Porex, without material cost to
Porex. As of September 10, 1997, 225 actions and 31 out-of-court claims were
pending against Porex. One of the pending federal actions, Donna L. Turner v.
Porex Technologies Corporation, et al., is styled as a class action. Of the
225 actions, 108 involve implants identified as distributed by Porex and 84
cases involve implants identified as not having been distributed by Porex. In
the remaining 33 actions, the implants have not been identified. The number of
claims made by individuals during Fiscal 1997 was similar to the number of
claims made during Fiscal 1996, both of which were significantly lower than
the number of claims made during Fiscal 1995.
 
  The typical case or claim alleges that the individual's mammary implants
caused one or more of a wide range of ailments. These implant cases and claims
generally raise difficult and complex factual and legal issues and are subject
to many uncertainties and complexities, including, but not limited to, the
facts and circumstances of each particular case or claim, the jurisdiction in
which each suit is brought, and differences in applicable law. The Company
does not have sufficient information to evaluate each case and claim.
 
  The Company believes that it has a valid claim for indemnification under the
Distribution Agreement with respect to any liabilities that could result from
pending actions or claims by recipients of implants or any similar actions or
claims that may be commenced in the future. However, Porex's right to
indemnification is subject to a disagreement with the Manufacturer. Pending
the resolution of such disagreement, the Manufacturer has been paying a
portion of the costs of the settled claims.
 
  In 1994, Porex was notified that its lead primary and excess insurance
carrier would not renew its then-existing insurance coverage after December
31, 1994 with respect to actions and claims arising out of Porex's
distribution of implants. In response, Porex exercised its right under the
policies with its lead carrier to purchase extended reporting period coverage
with respect to such actions and claims. Such coverage provides insurance,
subject to existing policy limits but for an unlimited time period, with
respect to actions and claims made after December 31, 1994 that are based on
events that occurred during the policy period. In addition, Porex has other
excess insurance where it has similarly purchased extended reporting period
coverage under its other excess insurance policies, all of which coverage will
by its terms expire by December 31, 1997 and Porex expects to purchase further
extended reporting period coverage from excess insurers to the extent such
coverage is reasonably available. The Company believes that its present
coverage, together with its insurance policies in effect on or before December
31, 1994, should provide adequate coverage against liabilities that could
result from actions or claims arising out of Porex's distribution of implants.
To the extent that certain of such actions and claims seek punitive and
compensatory damages arising out of alleged intentional torts, such damages,
if awarded, may or may not be covered, in whole or in part, by Porex's
insurance policies. In addition, Porex's recovery from its insurance carriers
is subject to policy limits and certain other conditions. Porex has been
expensing the retention amount under its policies as incurred.
 
  Although no assurances can be given, the Company believes that none of the
claims relating to the above-mentioned proceedings will have a material
adverse effect on the financial condition or results of operations of the
Company.
 
  The Company is subject to various claims and proceedings in the ordinary
course of business. Based on information currently available, the Company
believes that none of such current claims or proceedings, individually or in
the aggregate, will have a material adverse effect on the Company's financial
condition or results of operations.

COMPENSATION OF DIRECTORS
 
  Directors of the Company who are employees of the Company or Synetic will
not receive additional compensation for serving as directors of the Company.
Directors who are not employees of the Company or

Option Plan (the "Director Plan"), but will not receive cash compensation. The
Director Plan provides that on the first business day of each fiscal year of
the Company, each eligible director then in office will automatically be
granted an option to purchase     shares of Common Stock at an exercise price
equal to the fair market value of the Common Stock on the date of grant,
subject to vesting requirements. In addition, each such director will
automatically receive an option to purchase     shares of Common Stock,
subject to vesting requirements, at the time he is first elected to the Board.
The initial grants under the Director Plan will occur on the date of the
consummation of the Offerings (the "Effective Date") at an exercise price
equal to the initial public offering price. All directors of the Company
(other than the members of the Compensation Committee) are also eligible to
participate in the Class A Option Plan (as defined below). See "Management--
Compensation Pursuant to Plans and Arrangements of the Company--Class A Option
Plan."

    Synetic Common Stock will continue to vest and remain exercisable subject
    to such Named Executive Officers continued employment with the Company and
    the terms and conditions of the Synetic Class A Plan and Synetic Non-
    Officer Plan, as applicable.
(2) Based upon the total number of stock options granted to employees of
    Synetic.
(3) The estimated grant date present value reflected in the above table is
    determined using the Black-Scholes model. The material assumptions and
    adjustments incorporated in the Black-Scholes model in estimating the
    value of the options reflected in the above table include the following:
    (i) the respective option exercise price, specified above, equal to the
    fair market value of the underlying stock on the date of grant; (ii) the
    exercise of options within one year of the date that they become
    exercisable; (iii) a risk-free interest rate of 6.5% per annum; and (iv)
    volatility of 0.2722 calculated using daily prices of Synetic Common Stock
    during the period from December 14, 1994 to June 30, 1997. The ultimate
    values of the options will depend on the future market price of Synetic
    Common Stock, which cannot be forecast with reasonable accuracy. The
    actual value, if any, an optionee will realize upon exercise of an option
    will depend on the excess of the market value of Synetic Common Stock over
    the exercise price on the date the option is exercised. There is no
    assurance that the value realized by an optionee will be at or near the
    value estimated by the Black-Scholes model or any other model applied to
    value the options.

COMPENSATION PURSUANT TO PLANS AND ARRANGEMENTS OF THE COMPANY
 
  Set forth below is information with respect to certain benefit plans and
employment arrangements of the Company pursuant to which cash and non-cash
compensation was paid or distributed for Fiscal 1997, or is proposed to be
paid or distributed in the future, to the directors and executive officers of
the Company. The executive officers of the Company who are also directors or
executive officers of Synetic may continue to be included in Synetic's benefit
plans and employment arrangements. The executive officers of the Company who
are not executive officers of Synetic are not expected to be included in
Synetic's benefit plans. The Company has not borne, and is not expected to
bear in the future, any cost or expense of Synetic's benefit plans or
employment arrangements.
 
 CLASS A OPTION PLAN
 
  The Company has adopted (and Synetic, as the sole shareholder of the
Company, has approved) the Porex Corporation Class A Stock Option Plan (the
"Class A Plan"). The maximum number of shares of Common Stock that will be
subject to options under the Class A Plan is    , subject to adjustment in
accordance with the terms of the Class A Plan. The Class A Plan limits the
number of options that may be granted thereunder to an eligible employee in
any one-year period to no more than     (subject to adjustment in accordance
with the terms of the Class A Plan). It is presently anticipated that, in
order to comply with the requirements of Section 162(m) of the Internal
Revenue Code of 1986, as amended (the "Code"), the Class A Plan will be
submitted to the stockholders of the Company for their approval no later than
the first annual meeting of stockholders to be held more than twelve months
after the Effective Date.
 
  The Class A Plan will be administered by the Compensation Committee, all of
the members of which are nonemployee directors and "outside directors" within
the meaning of Rule 16b-3 under the Exchange Act and Section 162(m) of the
Code, respectively. The Compensation Committee will have the authority, within
limitations as set forth in the Class A Plan, to determine the persons to whom
options may be granted, the number of shares of Common Stock to be covered by
each option, the time or times at which the options may be granted or
exercised and the terms and provisions of the options to be granted.
 
  Eligibility for the grant of options under the Class A Plan is limited to
employees, officers and directors (excluding directors who serve on the
Compensation Committee) of the Company and its subsidiaries and certain
consultants, agents and key contractors of the Company and its subsidiaries.
It is anticipated that grants under
 
                                      34
<PAGE>
 
the Class A Plan will not be made to directors who are not employees of the
Company. Options granted under the Class A Plan may be either incentive stock
options within the meaning of Section 422 of the Code, or non-qualified stock
options, as determined by the Compensation Committee.
 
  Under the Class A Plan, the exercise price for an incentive stock option may
not be less than 100% (or 110% if the optionee owns or is deemed to own more
than 10% of the total combined voting power of all classes of stock of the
Company or a subsidiary) of the fair market value of the Common Stock on the
date of grant, as determined by the Board of Directors or the Compensation
Committee, and non-qualified stock options must have an exercise price of at
least 85% (100% in the case of designated eligible employees whose
compensation may be subject to the limitation on tax deductible compensation
imposed by Section 162(m) of the Code) of the fair market value of the Common
Stock on the date of grant (as determined by the Board of Directors or the
Compensation Committee).
 
  Under the Class A Plan, if there is a Change in Control (as defined below),
the Board of Directors may provide that options granted under the Class A Plan
will become exercisable in whole or in part, whether or not the options are
otherwise exercisable. A Change in Control is generally defined as the
occurrence of (i) any person (excluding Synetic and its subsidiaries, the
Company and its subsidiaries and certain affiliates of the Company, and the
Company's employee benefit plans) becoming the beneficial owner of 50% or more
of the voting power of Synetic's or the Company's securities, (ii) during a
24-month period the individuals who, at the beginning of such period,
constituted the Company's or Synetic's Board of Directors (the "Incumbent
Directors") ceasing to be a majority of the Board of Directors unless such new
directors were elected or recommended by the Incumbent Directors, (iii) the
approval by the stockholders of Synetic or the Company of a merger or
consolidation of Synetic or the Company, as the case may be, without the
consent of a majority of the Incumbent Directors, (iv) stockholder approval of
a sale of all or substantially all of the assets of the Company or Synetic, as
the case may be, or (v) adoption by the Company or Synetic of a plan of
liquidation. For purposes of the Class A Plan, a Change in Control of Synetic
will not result in any options becoming exercisable unless, immediately
preceding such Change in Control, Synetic was in control of the Company within
the meaning of the Exchange Act. In addition, the Compensation Committee may
determine that an option shall become exercisable in full or in part upon the
occurrence of such circumstances or events as the Compensation Committee
determines merit special consideration.
 
  The Class A Plan may be terminated and may be modified or amended by the
Board at any time; provided, however, that (i) no modification or amendment
will be effective without stockholder approval if such approval is required by
law or under the rules of Nasdaq National Market or any stock exchange on
which the Common Stock is listed and (ii) no such termination, modification or
amendment of the Class A Plan may adversely alter or affect the terms of any
then outstanding options previously granted without the consent of the
affected optionee.
 
 PENSION PLAN
 
  Employees of the Company and certain of its subsidiaries who satisfy certain
age and service requirements are eligible to participate in the Pension Plan
for Employees of Porex Technologies Corp. (the "Pension Plan"), a defined
benefit plan. The Company bears the entire cost of the Pension Plan. The
Company's contributions to the Pension Plan are computed on an actuarial basis
in order to fund the defined retirement benefits.
 
  Normal retirement benefits are payable monthly for life to a participant
upon retirement at his or her retirement date (i.e., age 65), and are equal to
1/12 of the sum of (a) 0.6% of the participant's average annual compensation
for the five consecutive calendar years that the participant's compensation
was the highest during the ten consecutive years of service immediately
preceding retirement ("Final Average Compensation"), multiplied by the
participant's credited years of service up to a maximum of 35 years, and (b)
0.6% of the participant's Final Average Compensation in excess of the average
annual Social Security taxable wage base for the 35-year period ending with
the year the participant would reach normal retirement age, multiplied by the
participant's credited years of service up to a maximum of 35 years. A
participant becomes 100% vested in his
 
                                      35
<PAGE>
 
or her accrued retirement benefit after completion of five years of service or
upon attainment of normal retirement at age 65. Retirement benefits are not
subject to any deduction for Social Security or other offset amounts.
 
  Under a defined benefit plan such as the Pension Plan, contributions
allocable to individual participants cannot be readily and accurately
calculated. The table below shows estimated annual retirement benefits for
executives at specified levels of remuneration and years of service. The
estimates assume that benefits commence at age 65 under a straight life
annuity form. The table discloses the benefits that an individual would
receive at age 65 if he participated in the Pension Plan for 15, 20, 25, 30
and 35 years.

  Messrs. Hannah, Smith, Wingo and Jackson have accrued 29, 25, 24 and 4
credited years of service under the Pension Plan, respectively. Sections
401(a)(17) and 415 of the Code limit the amount of compensation that may be
considered in computing benefits under a qualified retirement plan. For 1997,
the maximum amount of compensation allowed for use in calculating an
individual's pension benefits under the Pension Plan was $160,000. Messrs.
Hannah, Smith, Wingo and Jackson had annual remuneration covered by the
Pension Plan of $160,000, $152,647, $128,619 and $124,618, respectively, as of
January 1, 1997.
 
  Mr. Wernersbach does not participate in the Pension Plan. Porex Technologies
GmbH contributes DM 350 per month to a pension fund administered by a German
governmental agency for the benefit of Mr. Wernersbach. Pursuant to such
arrangement, Mr. Wernersbach is entitled to receive upon his retirement from
the Company after attaining age 65 and completing 10 years of service a lump
sum payment equal to the greater of (i) DM 70,000 (approximately $44,025 using
the Deutsche Mark Conversion Rate) and (ii) his then current account balance
(including earnings on the contributions).
 
SYNETIC PLANS
 
  The Named Executive Officers have been granted options ("Synetic Options")
to purchase shares of Synetic Common Stock pursuant to Synetic's stock option
plans. See "Management--Executive Compensation." The Synetic option plans are
administered by a stock option committee of Synetic and contain terms and
conditions which are substantially similar to the terms of the Class A Plan.
Subject to the terms and conditions of Synetic's stock option plans, the
Synetic Options will continue to vest and remain outstanding so long as the
respective Named Executive Officer remains in the employ of the Company.

                       SECURITY OWNERSHIP OF MANAGEMENT
 
  The Company is currently a wholly-owned subsidiary of Synetic, and
therefore, none of the directors or executive officers of the Company
beneficially own any of the Common Stock of the Company. The following table,
however, sets forth information with respect to the beneficial ownership of
Synetic Common Stock as of October 1, 1997 by (i) directors of the Company;
(ii) each of the Named Executive Officers; and (iii) all of the Company's

           TRANSACTIONS AND RELATIONSHIP WITH PRINCIPAL STOCKHOLDER
 
BACKGROUND
 
  Porex is a recently formed holding company, which owns all the outstanding
capital stock of PTC, through which Porex conducts its business operations.
Until the consummation of the Offerings, Porex has been a wholly-owned
subsidiary of Synetic. The Company does not depend on Synetic for any of its
revenues.
 
  Porex has been advised by Synetic's management that it believes that the
offering of a minority interest in Porex will enhance the value of Porex for
Synetic's stockholders. Synetic has directed its efforts in a new area of
business relating to the use of Internet-based technology to expand channels
of communication in the healthcare industry, which is intended to benefit
providers, payors and consumers of healthcare services by lowering healthcare
costs and improving patient outcomes. The Offerings create a separate public
entity focused entirely on the business of porous plastics and other porous
media with additional resources to pursue acquisitions and take other steps to
implement Porex's growth strategy. The Offerings also provide an opportunity
for Porex's management and employees to have a direct equity participation in
the Company.
 
SECURITY OWNERSHIP
 
  Prior to the Offerings, all of the Company's capital stock was owned by
Synetic. Upon completion of the Offerings, Synetic will own 15,000,000 shares,
or approximately 86% of the outstanding shares of the Company's Common Stock
(approximately 84% if the Underwriters' over-allotment options are exercised
in full). Synetic will have the ability to control the vote on matters
submitted to a vote of the Company's stockholders and will also be able to
elect the Board of Directors of the Company. Certain directors and executive
officers of the Company own shares of Synetic Common Stock. See "Risk
Factors--Substantial Control by Synetic" and "Security Ownership of
Management." The address of Synetic is River Drive Center 2, 669 River Drive,
Elmwood Park, New Jersey 07407.
 
CONFLICTS OF INTEREST
 
  Upon completion of the Offerings, Synetic will retain effective control of
the Company and may be in a position to cause the Company to merge,
consolidate, liquidate or sell all or a substantial portion of its assets on
terms determined by Synetic. Certain of Synetic's executive officers and
directors are officers of or directors of the Company. Such directors and
officers of the Company who are also directors or officers of Synetic are in
positions involving possible conflicts of interest with respect to certain
transactions that may occur and that could affect the Company, such as
transactions involving business dealings between the Company and Synetic, the
disposition of acquisition opportunities, the issuance of additional Common
Stock or other securities of the Company and other matters involving conflicts
that cannot now be foreseen.
 
  It is contemplated that after the Offerings, officers of the Company who are
also executive officers of Synetic will continue to spend a substantial amount
of their business time as directors or officers of Synetic and its other
subsidiaries and may be engaged in other business activities, consistent with
their other employment agreements, if any. See "Risk Factors--Substantial
Control by Synetic" and "Management."
 
CERTAIN AGREEMENTS
 
  The Company and Synetic will enter into a number of agreements for the
purpose of defining the ongoing relationship between the two companies.
Additional or modified agreements, arrangements and transactions may be
entered into by the Company and Synetic after the completion of the Offerings.
Any such future agreements, arrangements and transactions will be determined
through negotiations between the Company and Synetic, as the case may be.
Following the Offerings, the Company will continue to be controlled by Synetic
and consequently such negotiations will not be arm's-length.
 
 
                                      38
<PAGE>
 
  The following is a summary of certain proposed agreements between the
Company and Synetic.
 
  Tax Sharing Agreement. The Company and Synetic will enter into a Tax Sharing
Agreement providing for (i) payment of federal income taxes for periods during
which the Company and Synetic are included in the same consolidated group for
federal income tax purposes, (ii) allocation of responsibility for the filing
of such tax returns, (iii) conduct of tax audits and the handling of tax
controversies and (iv) various related matters. For periods during which the
Company and its subsidiaries are included in Synetic's consolidated federal
income tax returns, the Company and each of its subsidiaries will be required
to pay to Synetic an amount equal to their federal income tax liability,
determined as if the Company and each of its subsidiaries had filed separate
federal income tax returns.
 
  Services Agreement. The Company and Synetic will enter into a Services
Agreement, pursuant to which Synetic will provide the Company with services
relating primarily to financial, tax and legal advice in connection with the
Company's acquisition program and other technical services as required. The
Company will pay the actual costs of providing these services. Such costs will
include an allocable portion of the base compensation and other related
expenses (other than Synetic's benefit plans and employment agreements and
arrangements) of the officers of Synetic who serve as officers of the Company.
This agreement will be terminable by either party upon 90 days' prior written
notice, at the end of any quarter. Allocated charges for normal, recurring
services provided by Synetic to the Company in the past have not been
material, nor are they expected to be material in the future. However, the
cost of providing services in connection with the Company's acquisition
program or of extraordinary services, may be significant in the future,
although no estimate of such costs is presently possible. See Note 7 of the
Notes to Consolidated Financial Statements.
 
  Indemnification Agreement. The Company and Synetic will enter into an
Indemnification Agreement, under the terms of which the Company will indemnify
and hold harmless Synetic with respect to any and all claims, losses, damages,
liabilities, costs and expenses that arise from or are based on the operations
of the business of the Company before or after the date of the consummation of
the Offerings. Similarly, Synetic will indemnify and hold harmless the Company
with respect to any and all claims, losses, damages, liabilities, costs and
expenses that arise from or are based on the operations of Synetic other than
the business of the Company before or after the date of the consummation of
the Offerings.
 
  Registration Rights Agreement. The Company and Synetic will enter into a
Registration Rights Agreement. Under the terms of such agreement, Synetic will
have the right, subject to certain terms and conditions, to require the
Company, at the expense of Synetic, to file up to three registration
statements, if requested by Synetic, for the public offering of any equity
securities of the Company then held by Synetic. Such right may be exercised
after 180 days following the date of this Prospectus; provided, however, that
the Company will not be required to have more than one registration statement
declared effective in each year. Synetic has informed the Company that it has
no present intention of exercising such registration rights or otherwise
selling any shares of the Company's Common Stock which it owns.
 
  Credit Agreement. Synetic intends to make available to the Company a
revolving line of credit to be used by the Company for the purpose of making
acquisitions. Terms of such line of credit, including the amount, interest
rate and security, if any, have not been determined, and if such terms are not
agreed upon by Synetic and the Company, such line of credit may not be made
available.

<PAGE>
 
                         DESCRIPTION OF CAPITAL STOCK
 
  The Company's authorized capital consists of 50,000,000 shares of Common
Stock, par value $.01 per share, and 10,000,000 shares of Preferred Stock,
$.01 par value per share. No shares of Preferred Stock are outstanding as of
the date of this Prospectus. Immediately prior to the Offerings, 15,000,000
shares of Common Stock were issued and outstanding. Immediately following the
Offerings, 17,500,000 shares of Common Stock will be issued and outstanding.
 
PREFERRED STOCK
 
  The Preferred Stock may be issued from time to time in one or more series,
without stockholder approval. The Board of Directors is authorized to
determine (subject to limitations prescribed by law) the rights including
voting rights, if any, preferences, terms and limitations to be granted to and
imposed upon any wholly unissued series of Preferred Stock and to fix the
number of shares of any series of Preferred Stock and the designation of any
such series. The Company has no present plans to issue any shares of Preferred
Stock. Because of its broad discretion with respect to the creation and
issuance of any series of Preferred Stock without stockholder approval, the
Board of Directors could adversely affect the voting power of Common Stock.
The issuance of Preferred Stock may have the effect of delaying, deferring or
preventing a change in control of the Company.
 
COMMON STOCK
 
  Holders of record of Common Stock are entitled to one vote per share on all
matters upon which shareholders have the right to vote. There are no
cumulative voting rights. All issued and outstanding shares of Common Stock
are, and the Common Stock to be sold in the Offerings, when issued and paid
for, will be, validly issued, fully paid and non-assessable. Holders of Common
Stock are entitled to such dividends as may be declared from time to time by
the Board of Directors out of funds legally available for that purpose. The
Company does not anticipate paying any cash dividends in the foreseeable
future. See "Dividend Policy." Upon dissolution, holders of Common Stock are
entitled to share pro rata in the assets of the Company remaining after
payment in full of all of its liabilities and obligations, including payment
of the liquidation preference, if any, of any Preferred Stock then
outstanding.
 
CERTAIN PROVISIONS OF THE CERTIFICATE OF INCORPORATION, BY-LAWS AND DELAWARE
LAW
 
  The Company's Certificate of Incorporation and By-laws do not provide for a
staggered Board of Directors. The Certificate of Incorporation and By-laws
provide that special meetings of the Company may be called only by a majority
of the entire Board of Directors. In addition, the By-laws establish an
advance notice procedure for stockholder proposals to be considered at annual
meetings of stockholders. Notice must be received by the Company not less than
60 days nor more than 90 days prior to the anniversary date of the immediately
preceding annual meeting of stockholders and must contain certain specified
information concerning the matters to be brought before the meeting and
concerning the stockholders submitting the proposal. Such provisions of the
Company's Certificate of Incorporation and By-laws could be deemed to have an
anti-takeover effect.
 
  The Company's Certificate of Incorporation provides that so long as the
Company is controlled by, or under common control with, Synetic (i) directors
or officers of the Company who are also directors or officers of Synetic are
obligated to present a potential acquisition of a business engaged in the
design, manufacture or distribution of porous materials (a "Porous Materials
Business") to the Company and may present such acquisition to Synetic only
upon rejection of such acquisition by the Board of Directors of the Company,
(ii) directors or officers of the Company who are also directors or officers
of Synetic have no obligation to present a potential acquisition in the
healthcare communications area to the Company and may present such acquisition
to the Company only upon rejection of such acquisition by the Board of
Directors of Synetic and (iii) directors or officers of the Company who are
also directors or officers of Synetic have no obligation to present a
potential acquisition to the Company of a business that is not a Porous
Materials Business.
 
                                      40
<PAGE>
 
  The Company is subject to the provisions of Section 203 of the Delaware
General Corporation Law. In general, the statute prohibits a publicly held
Delaware corporation from engaging in a "business combination" with an
"interested stockholder" for a period of three years after the date of the
transaction in which the person became an interested stockholder, unless (i)
prior to such date, the board of directors approved either the business
combination or the transaction that resulted in the stockholder becoming an
interested stockholder, (ii) upon consummation of the transaction that
resulted in such person becoming an interested stockholder, the interested
stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced (excluding, for purposes of
determining the number of shares outstanding, shares owned by certain
directors or certain employee stock plans), or (iii) on or after the date the
stockholder became an interested stockholder, the business combination is
approved by the board of directors and authorized by the affirmative vote (and
not by written consent) of at least two-thirds of the outstanding voting stock
excluding that stock owned by the interested stockholder. A "business
combination" includes a merger, asset sale or other transaction resulting in a
financial benefit to the interested stockholder. An "interested stockholder"
is a person who (other than the corporation and any direct or indirect
majority owned subsidiary of the corporation), together with affiliates and
associates, owns (or, as an affiliate or associate, within three years prior,
did own) 15% or more of the corporation's outstanding voting stock. The
application of Section 203 could have the effect of delaying or preventing a
change of control of the Company.
 
TRANSFER AGENT AND REGISTRAR
 
  The Company has appointed Registrar and Transfer Company as the transfer
agent and registrar for the Common Stock.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Prior to the Offerings, there has been no public market for the Common
Stock. No information is currently available and no prediction can be made as
to the timing or amount of future sales of shares, or the effect, if any, that
market sales of shares or the availability of shares for sale will have on the
market price prevailing from time to time. Nevertheless, sales of substantial
amounts of Common Stock (including shares issuable upon exercise of stock
options) in the public market after the lapse of the restrictions described
below, or the perception that such sales may occur, could materially and
adversely affect the prevailing market prices for the Common Stock and the
ability of the Company to raise equity capital in the future. See "Risk
Factors--Shares Eligible for Future Sale."
 
  After completion of the Offerings, the Company will have 17,500,000 shares
of Common Stock outstanding (17,875,000 shares if the Underwriters' over-
allotment options are exercised in full). All of the 2,500,000 shares of
Common Stock offered in the Offerings (2,875,000 shares if the Underwriters'
over-allotment options are exercised in full), will be freely tradeable
without restriction or further registration under the Securities Act, unless
purchased by "affiliates" of the Company, as that term is defined in Rule 144,
described below. All of the shares of Common Stock held by Synetic are
"Restricted Securities," as that term is defined in Rule 144, and may not be
sold in the absence of registration other than in accordance with Rule 144 or
another exemption from registration under the Securities Act.
 
  In general, under Rule 144 as currently in effect, any affiliate of the
Company or any person (or persons whose shares are aggregated in accordance
with the Rule) who has beneficially owned Common Stock which is treated as
Restricted Securities for at least one year would be entitled to sell within
any three-month period a number of shares that does not exceed the greater of
1% of the outstanding shares of Common Stock (approximately 175,000 shares
based upon the number of shares outstanding after the Offerings (or 178,750
shares if the Underwriters' over-allotment options are exercised in full)) or
the reported average weekly trading volume in the Common Stock during the four
weeks preceding the date on which notice of such sale was filed under Rule
144. Sales under Rule 144 are also subject to certain manner of sale
restrictions and notice requirements and to the availability of current public
information concerning the Company. In addition, affiliates
 
                                      41
<PAGE>
 
of the Company must comply with the restrictions and requirements of Rule 144
(other than the one-year holding period requirement) in order to sell Common
Stock that are not Restricted Securities (such as Common Stock acquired by
affiliates in market transactions). Further, if a period of at least two years
has elapsed from the date Restricted Securities were acquired from the Company
or an affiliate of the Company, a holder of such Restricted Securities who is
not an affiliate at the time of the sale and who has not been an affiliate for
at least three months prior to such sale would be entitled to sell the shares
immediately without regard to the volume, manner of sale, notice and public
information requirements of Rule 144.
 
  Upon consummation of the Offerings, Synetic will own approximately 86% (84%
if the Underwriters' over-allotment options are exercised in full) of the
outstanding Common Stock. Synetic has advised the Company that it currently
has no plans to reduce its ownership interest following the Offerings.
However, Synetic is not subject to any contractual obligation to retain its
controlling interest, except that Synetic has agreed not to sell or otherwise
dispose of any shares of the Company for a period of 180 days after the date
of the Prospectus without the prior written consent of Merrill Lynch. In
addition, subject to certain exceptions, the Company has agreed not to sell or
otherwise dispose of any shares of Common Stock for such 180-day period
without the prior written consent of Merrill Lynch. See "Underwriting."
 
   CERTAIN UNITED STATES FEDERAL TAX CONSIDERATIONS FOR NON-U.S. HOLDERS OF
                                 COMMON STOCK
 
  The following is a general discussion of certain U.S. federal income and
estate tax consequences of the ownership and disposition of Common Stock by
"Non-U.S. Holders." In general, a "Non-U.S. Holder" is an individual or entity
other than: (i) a citizen or resident of the United States; (ii) a corporation
or partnership created or organized in the United States or under the laws of
the United States or of any state; (iii) an estate, the income of which is
includible in gross income for U.S. federal income tax purposes regardless of
its source; or (iv) a trust if a court within the United States is able to
exercise primary supervision over the administration of the trust and one or
more U.S. persons have the authority to control all substantial decisions of
the trust. This discussion does not address all aspects of U.S. federal income
and estate taxation and does not deal with foreign, state and local
consequences that may be relevant to Non-U.S. Holders in light of their
personal circumstances, or to certain types of Non-U.S. Holders which may be
subject to special treatment under U.S. federal income tax laws (for example,
certain U.S. expatriates, insurance companies, tax-exempt organizations,
financial institutions and broker-dealers). Furthermore, this discussion is
based on provisions of the Internal Revenue Code of 1986, amended (the "Code")
existing and proposed regulations promulgated thereunder and administrative
and judicial interpretations thereof, all as of the date hereof, and all of
which are subject to change, possibly with retroactive effect. PROSPECTIVE
INVESTORS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE U.S.
FEDERAL, STATE, LOCAL AND NON-U.S. INCOME AND OTHER TAX CONSEQUENCES OF
HOLDING AND DISPOSING OF SHARES OF COMMON STOCK.
 
  An individual may, subject to certain exceptions, be deemed to be a resident
alien (as opposed to a nonresident alien) by virtue of being present in the
United States for at least 31 days in the calendar year and for an aggregate
of at least 183 days during a three-year period ending in the current calendar
year (counting for such purposes all of the days present in the current year,
one-third of the days present in the immediately preceding year and one-sixth
of the days present in the second preceding year). Resident aliens are subject
to U.S. federal tax as if they were U.S. citizens.
 
DIVIDENDS
 
  The Company does not expect to pay any cash dividends in the foreseeable
future. See "Dividend Policy." In the event, however, that dividends are paid
on shares of Common Stock, dividends paid to a Non-U.S. Holder will generally
be subject to U.S. withholding tax at a 30% rate (or a lower rate prescribed
by an applicable tax
 
                                      42
<PAGE>
 
treaty) unless the dividends are either (i) effectively connected with a trade
or business carried on by the Non-U.S. Holder within the United States and the
Non-U.S. Holder provides the payor with proper documentation, as discussed
below, or (ii) if certain income tax treaties apply, attributable to a
permanent establishment in the United States maintained by the Non-U.S.
Holder. Dividends effectively connected with such a U.S. trade or business or
attributable to such a U.S. permanent establishment generally will not be
subject to withholding tax (if the Non-U.S. Holder files certain forms,
including, currently, Internal Revenue Service ("IRS") Form 4224, and after
December 31, 1998, subject to certain transition rules, a Form W-8, with the
pavor of the dividend) and generally will be subject to U.S. federal income
tax on a net income basis, in the same manner as if the Non-U.S. Holder were a
resident of the United States. In the case of a Non-U.S. Holder that is a
corporation, dividend income so connected or attributable may also be subject
to the branch profits tax (which is generally imposed on a foreign corporation
on the repatriation from the United States of its effectively connected
earnings and profits subject to certain adjustments) at a 30% rate (or a lower
rate prescribed by an applicable income tax treaty). For purposes of
determining whether tax is to be withheld at a 30% rate or at a lower rate as
prescribed by an applicable tax treaty, current law permits the Company to
presume that dividends paid prior to January 1, 1999 to an address in a
foreign country are paid to a resident of such country absent knowledge that
such presumption is not warranted. However, under newly issued Treasury
regulations, in the case of dividends paid after December 31, 1998, a Non-U.S.
Holder generally will be subject to United States withholding tax at a 31%
rate under the backup withholding rules described below, rather than at a 30%
rate or a reduced rate under an income tax treaty, as described above, unless
certain Internal Revenue Service ("IRS") certification procedures (or, in the
case of payments made outside the United States with respect to an offshore
account, certain IRS documentary evidence procedures) are complied with.
Further, in order to claim the benefit of an applicable income tax treaty rate
for dividends paid after December 31, 1998, a Non-U.S. Holder must comply with
IRS certification requirements. Certain IRS certification and disclosure
requirements must be complied with in order to be exempt from withholding
under the effectively connected income exemption. The new regulations also
provide special rules for dividend payments made to foreign intermediaries,
U.S. or foreign wholly owned entities that are disregarded for U.S. federal
income tax purposes and entities that are treated as fiscally transparent in
the United States, the applicable income tax treaty jurisdiction, or both.
Prospective investors should consult with their own tax advisors concerning
the effect, if any, of the adoption of these new regulations on an investment
in the Common Stock.
 
  A Non-U.S. Holder that is eligible for a reduced rate of U.S. withholding
tax pursuant to an income tax treaty may obtain a refund of any excess amounts
currently withheld by filing an appropriate claim for refund with the IRS.
 
SALE OF COMMON STOCK
 
  In general, a Non-U.S. Holder will not be subject to U.S. federal income tax
on any gain recognized upon the disposition of Common Stock unless: (i) the
gain is effectively connected with a trade or business carried on by the Non-
U.S. Holder within the United States or, alternatively, if certain tax
treaties apply, attributable to a permanent establishment in the United States
maintained by the Non-U.S. Holder (and in either such case, the branch profits
tax may also apply if the Non-U.S. Holder is a corporation); (ii) in the case
of an individual Non-U.S. Holder who holds shares of Common Stock as capital
assets, such individual is present in the United States for 183 days or more
in the taxable year of disposition, and certain other conditions are met; or
(iii) the Company is or has been a United States real property holding
corporation (a "USRPHC") for United States federal income tax purposes at any
time within the shorter of the five-year period preceding such disposition or
such Non-U.S. Holder's holding period. A corporation is a USRPHC if the fair
market value of the U.S. real property interests held by the corporation is
50% or more of the aggregate fair market value of certain assets of the
corporation. The Company believes that it is not likely to become and is not
currently a USRPHC. If the Company were or were to become a USRPHC, gains
realized upon a disposition of Common Stock by a Non-U.S. Holder which did not
directly or indirectly own more than 5% of the Common Stock during the shorter
of the periods described
 
                                      43
<PAGE>
 
above generally would not be subject to U.S. federal income tax so long as the
Common Stock is "regularly traded" on an established securities market.
 
  If a Non-U.S. Holder who is an individual falls under clause (i) above, such
individual generally will be taxed on the net gain derived from a sale of
Common Stock under regular graduated U.S. federal income tax rates. If an
individual Non-U.S. Holder falls under clause (ii) above, such individual
generally will be subject to a flat 30% tax on the gain derived from a sale,
which may be offset by certain U.S. capital losses (notwithstanding the fact
that such individual is not considered a resident alien of the United States).
Thus, individual Non-U.S. Holders who have spent (or expect to spend) more
than a de minimis period of time in the United States in the taxable year in
which they contemplate a sale of Common Stock are urged to consult their tax
advisors prior to the sale as to the U.S. tax consequences of such sale.
 
  If a Non-U.S. Holder that is a foreign corporation falls under clause (i)
above, it generally will be taxed on its net gain under regular graduated U.S.
federal income tax rates and, in addition, will be subject to the branch
profits tax equal to 30% of its "effectively connected earnings and profits,"
within the meaning of the Code for the taxable year, as adjusted for certain
items, unless it qualifies for a lower rate under an applicable tax treaty.
 
ESTATE TAX
 
  Common Stock owned or treated as owned by an individual who is not a citizen
or resident (as defined for U.S. federal estate tax purposes) of the United
States at the time of death will be includible in the individual's gross
estate for U.S. federal estate tax purposes, unless an applicable estate tax
treaty provides otherwise, and therefore may be subject to U.S. federal estate
tax.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
  The Company must report annually to the IRS and to each Non-U.S. Holder the
amount of dividends paid to, and the tax withheld with respect to, each Non-
U.S. Holder. These reporting requirements apply regardless of whether
withholding was not required because the dividends were effectively connected
with a U.S. trade or business of the Non-U.S. Holder or reduced or eliminated
by an applicable tax treaty. Copies of this information also may be made
available under the provisions of a specific treaty or agreement with the tax
authorities in the country in which the Non-U.S. Holder resides or is
established.
 
  Under current rules, United States backup withholding (which generally is
imposed at the rate of 31% on certain payments to persons that fail to furnish
the information required under the U.S. information reporting requirements)
generally will not apply (i) to dividends paid on Common Stock to a Non-U.S.
Holder that is subject to withholding at the 30% rate (or that is subject to
withholding at a reduced rate under an applicable treaty) or (ii) before
January 1, 1999, to dividends paid to a Non-U.S. Holder at an address outside
the United States. However, under newly issued regulations, in the case of
dividends paid after December 31, 1998 a Non-U.S. Holder generally will be
subject to backup withholding at a 31% rate, unless certain IRS certification
procedures (or, in the case of payments made outside the United States with
respect to an offshore account, certain IRS documentary evidence procedures)
are complied with, directly or through an intermediary.
 
  The payment of proceeds from the disposition of Common Stock to or through a
U.S. office of a broker will be subject to information reporting and backup
withholding unless either (i) the Non-U.S. Holder is a corporation or other
exempt recipient meeting certain requirements or (ii) the Non-U.S. Holder
provides a valid Form W-8. The payment of proceeds from the disposition of
Common Stock to or through a non-U.S. office of a non-U.S. broker generally
will not be subject to backup withholding and information reporting. Before
January 1, 1999, however, in the case of proceeds from the disposition of
Common Stock effected at a non-U.S. office of a broker that is: (i) a U.S.
person; (ii) a "controlled foreign corporation" for U.S. federal income tax
purposes; or (iii) a foreign person 50% or more of whose gross income from
certain periods is effectively connected with a U.S. trade or business, such
payments will not be subject to backup withholding unless such broker has
actual knowledge that the owner is not a Non-U.S. Holder but will be subject
to information reporting, unless such
 
                                      44
<PAGE>
 
broker has documentary evidence in its files that the owner is a Non-U.S.
Holder and certain other conditions are met. Further, after December 31, 1998,
under the newly issued regulations referred to above, information reporting
and backup withholding may apply to payments of the gross proceeds from the
sale or redemption of Common Stock effected through foreign offices of brokers
having any of a broader class of connections with the United States unless
certain certification requirements are complied with. Prospective investors
should consult with their own tax advisors regarding these regulations, and in
particular with respect to whether the use of a particular broker would
subject the investor to these rules.
 
  Backup withholding is not an additional tax. Any amounts withheld under the
backup withholding rules from a payment to a Non-U.S. Holder will be refunded
or credited against the Non-U.S. Holder's U.S. federal income tax liability,
if any, provided that the required information is furnished to the IRS.

500,000 shares of Common Stock to the International Managers (as defined
below), the Company has agreed to sell to each of the U.S. Underwriters, and
each of the U.S. Underwriters for whom Merrill Lynch, Pierce, Fenner & Smith
Incorporated ("Merrill Lynch") and Prudential Securities Incorporated are
acting as representatives (the "U.S. Representatives"), has severally agreed
to purchase from the Company, the number of shares of Common Stock set forth

</TABLE>
 
  The Company has also entered into an international purchase agreement (the
"International Purchase Agreement" and, together with the U.S. Purchase
Agreement, the "Purchase Agreements") with certain underwriters outside the
United States and Canada (the "International Managers" and, together with the
U.S. Underwriters, the "Underwriters") for whom Merrill Lynch International
and Prudential-Bache Securities (U.K.) Inc. are acting as representatives (the
"International Representatives" and, together with its U.S. Representatives,
the "Representatives"). Subject to the terms and conditions set forth in the
International Purchase Agreement, and concurrently with the sale of 2,000,000
shares of Common Stock to the U.S. Underwriters pursuant to the U.S. Purchase
Agreement, the Company has agreed to sell to the International Managers, and
the International Managers severally have agreed to purchase, an aggregate of
500,000 shares of Common Stock. The initial public offering price per share
and the underwriting discount per share of Common Stock are identical under
the U.S. Purchase Agreement and the International Purchase Agreement.
 
  In each Purchase Agreement, the several U.S. Underwriters and the several
International Managers, respectively, have agreed, subject to the terms and
conditions set forth in such Purchase Agreement, to purchase all the shares of
Common Stock offered hereby, if any are purchased. In the event of default by
an Underwriter, each Purchase Agreement provides that, in certain
circumstances, purchase commitments of the nondefaulting Underwriters may be
increased or the Purchase Agreement may be terminated. The sale of Common
Stock to the U.S. Underwriters is conditioned upon the sale of shares of
Common Stock to the International Managers.
 
  The U.S. Underwriters and the International Managers have entered into an
intersyndicate agreement (the "Intersyndicate Agreement") that provides for
the coordination of their activities. Pursuant to the Intersyndicate
Agreement, the U.S. Underwriters and the International Managers are permitted
to sell shares of Common Stock to each other for purposes of resale at the
initial public offering price set forth on the cover page of this Prospectus,
less an amount not greater than the selling concession. Under the terms of the
Intersyndicate Agreement, the U.S. Underwriters and any dealer to whom they
sell shares of Common Stock will not offer to sell or sell shares of Common
Stock to persons who are non-U.S. or non-Canadian persons or to persons they
believe intend to resell to persons who are non-U.S. or non-Canadian persons,
and the International Managers and any dealer to whom they sell shares of
Common Stock will not offer to sell or sell shares of Common Stock to U.S.
persons or Canadian persons or to persons they believe intend to resell to
U.S. persons or Canadian persons, except, in each case, for transactions
pursuant to the Intersyndicate Agreement.
 
  The U.S. Representatives have advised the Company that they propose
initially to offer the shares of Common Stock to the public at the initial
public offering price set forth on the cover page of this Prospectus,
 
                                      46
<PAGE>
 
and to certain dealers at such price less a concession not in excess of $  per
share of Common Stock. The U.S. Underwriters may allow, and such dealers may
reallow, a discount not in excess of $  per share of Common Stock to certain
other dealers. After the initial public offering, the public offering price,
concession and discount may be changed.
 
  At the request of the Company, the U.S. Underwriters have reserved up to
250,000 shares of Common Stock for sale at the initial public offering price
to directors, employees, consultants, business associates and related persons
of the Company and Synetic. The number of shares of Common Stock available for
sale to the general public will be reduced to the extent such persons purchase
such reserved shares. Any reserved shares which are not so purchased will be
offered by the U.S. Underwriters to the general public on the same basis as
the other shares offered hereby. Employees of the Company who purchase
reserved shares will be required to agree not to sell, offer to otherwise
dispose of any such reserved shares for a period of three months after the
date of this Prospectus.
 
  The Company and Synetic have agreed, subject to certain exceptions, not to,
directly or indirectly, (i) sell, grant any option to purchase or otherwise
transfer or dispose of any Common Stock or securities convertible into or
exchangeable or exercisable for Common Stock or file a registration statement
under the Securities Act with respect to the foregoing or (ii) enter into any
swap or other agreement or transaction that transfers, in whole or part, the
economic consequence of ownership of the Common Stock, without the prior
written consent of Merrill Lynch, for a period of 180 days after the date of
this Prospectus. The foregoing sentence shall not apply to (a) the shares of
Common Stock to be sold hereunder, (b) any shares of Common Stock issued by
the Company upon the exercise of an option or warrant or the conversion of a
security outstanding on the date hereof and referred to in this Prospectus,
(c) any shares of Common Stock issued or options to purchase Common Stock
granted pursuant to existing employee benefit or stock option plans of the
Company referred to in this Prospectus, (d) any shares of Common Stock issued
pursuant to any stock option plan for non-employee directors or (e) any shares
of Common Stock issued in connection with acquisitions or similar transactions
by the Company.
 
  The Company has granted an option to the U.S. Underwriters, exercisable
within 30 days after the date of this Prospectus, to purchase up to an
aggregate of 300,000 additional shares of Common Stock at the initial public
offering price set forth on the cover page of this Prospectus, less the
underwriting discount. The U.S. Underwriters may exercise this option only to
cover over-allotments, if any, made on the sale of the Common Stock offered
hereby. To the extent that the U.S. Underwriters exercise this option, each
U.S. Underwriter will be obligated, subject to certain conditions, to purchase
a number of additional shares of Common Stock proportionate to such U.S.
Underwriter's initial amount reflected in the foregoing table. The Company has
also granted an option to the International Managers, exercisable within 30
days after the date of this Prospectus, to purchase up to an additional 75,000
shares of Common Stock to cover over-allotments, if any, on terms similar to
those granted to U.S. Underwriters.
 
  Prior to the Offerings, there has been no public market for the Common
Stock. The initial public offering price for the Common Stock was determined
by negotiation between the Company and the Representatives. The factors
considered in determining the initial public offering price, in addition to
prevailing market conditions, are price-earnings ratios of publicly traded
companies that the Representatives believe to be comparable to the Company,
certain financial information of the Company, the history of, and the
prospects for, the Company and the industry in which it competes, and an
assessment of the Company's management, its past and present operations, the
prospects for, and timing of, future revenues of the Company, the present
state of the Company's development, and the above factors in relation to
market values and various valuation measures of other companies engaged in
activities similar to the Company. There can be no assurance that an active
trading market will develop for the Common Stock or that the Common Stock will
trade in the public market subsequent to the Offerings at or above the initial
public offering price.
 
  The Company has agreed to indemnify the several U.S. Underwriters against
certain liabilities, including liabilities under the Securities Act of 1933,
as amended, or to contribute to payments the Underwriters may be required to
make in respect thereof.

  The U.S. Representatives have advised the Company that the Underwriters do
not intend to confirm sales of Common Stock offered hereby to any accounts
over which they exercise discretionary authority.
 
  Until the distribution of the Common Stock is completed, rules of the
Securities and Exchange Commission may limit the ability of the Underwriters
and certain selling group members to bid for and purchase the Common Stock. As
an exception to these rules, the U.S. Representatives are permitted to engage
in certain transactions that stabilize the price of the Common Stock. Such
transactions consist of bids or purchases for the purpose of pegging, fixing
or maintaining the price of the Common Stock.
 
  If the Underwriters create a short position in the Common Stock in
connection with the Offerings, (i.e., if they sell more shares of Common Stock
than are set forth on the cover page of this Prospectus), the U.S.
Representatives may reduce that short position by purchasing Common Stock in
the open market. The U.S. Representatives may also elect to reduce any short
position by exercising all or part of the over-allotment options described
above.
 
  The U.S. Representatives may also impose a penalty bid on certain
Underwriters and selling group members. This means that if the U.S.
Representatives purchase shares of Common Stock in the open market to reduce
the Underwriters' short position or to stabilize the price of the Common
Stock, they may reclaim the amount of the selling concession from the
Underwriters and selling group members who sold those shares as part of the
Offerings.
 
  In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher
than it might be in the absence of such purchases. The imposition of a penalty
bid might also have an effect on the price of a security to the extent that it
were to discourage resales of the security by purchasers in the Offerings.
 
  Neither the Company nor any of the U.S. Underwriters makes any
representation or prediction as to the direction or magnitude of any effect
that the transactions described above may have on the price of the Common
Stock. In addition, neither the Company nor any of the Underwriters makes any
representation that the Representatives will engage in such transaction or
that such transactions, once commenced, will not be discontinued without
notice.
 
                                 LEGAL MATTERS
 
  The validity of the shares of Common Stock offered hereby will be passed
upon for the Company by Shearman & Sterling, New York, New York. Certain legal
matters will be passed upon for the Underwriters by Brown & Wood LLP, New
York, New York.
 
  The statements of law in this Prospectus under the caption "Risk Factors--
Regulatory Requirements" and under the caption "Business--Regulation," are
based upon the opinion of Kegler, Brown, Hill & Ritter, Columbus, Ohio,
special regulatory counsel to the Company.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
TO THE BOARD OF DIRECTORS OF POREX CORPORATION:
 
  We have audited the accompanying consolidated balance sheets of Porex
Corporation (a Delaware corporation) and subsidiaries as of June 30, 1996 and
1997, and the related consolidated statements of income, changes in
stockholder's equity and cash flows for each of the three years in the period
ended June 30, 1997. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these consolidated financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Porex Corporation and
subsidiaries as of June 30, 1996 and 1997, and the results of their operations
and their cash flows for each of the three years in the period ended June 30,
1997 in conformity with generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  In November 1997, Synetic, Inc. ("Synetic") formed Porex Corporation, a
Delaware corporation ("Porex"). In connection therewith Porex issued
15,000,000 shares of Common Stock, $.01 par value, to Synetic in exchange for
all of the outstanding capital stock of its wholly-owned subsidiary, Porex
Technologies Corp. ("PTC"). This reorganization has been accounted for at
historical book values in a manner similar to a pooling-of-interests. These
consolidated financial statements present the financial position and results
of operations of Porex and PTC and its subsidiaries (collectively, the
"Company"), as if this reorganization had occurred as of the first day of the
earliest period presented.
 
  Porex designs, manufactures and distributes porous and solid plastic
components and products for use in healthcare, consumer and industrial
applications.
 
 Principles of Consolidation
 
  The accompanying consolidated financial statements include the accounts of
the Company, after elimination of all material intercompany accounts and
transactions.
 
 Cash and Cash Equivalents
 
  The Company considers all liquid investment instruments with an original
maturity of three months or less to be the equivalent of cash for purposes of
balance sheet presentation and for the consolidated statements of cash flows.
These short-term investments are stated at cost, which approximates market.
 
 Inventories
 
  Inventories are stated at the lower of first-in, first-out cost or market.
Cost includes raw materials, direct labor, and manufacturing overhead. Market
is based on current replacement cost for raw materials and supplies and on net
realizable value for work-in-process and finished goods. Inventories consisted
of the following (in thousands):

 Property, Plant and Equipment
 
  Property, plant and equipment are stated at cost. For financial reporting
purposes, depreciation is provided principally on the straight-line method
over the estimated useful lives of the assets. Annual depreciation rates range
from 2% to 10% for buildings and improvements and from 7% to 33% for machinery
and equipment and furniture and fixtures. For income tax purposes, certain
assets are depreciated using accelerated methods. Expenditures for
maintenance, repair and renewals of minor items are charged to operations as
incurred. Major improvements are capitalized.

 Goodwill
 
  The excess of net assets acquired over underlying book values ("goodwill")

assigned to goodwill based upon expectations of future cash flows and
operating income generated by the underlying intangible assets.

  Development costs are expensed as incurred. Total development expenses were
$1,490,000, $2,014,000 and $1,791,000 for the years ended June 30, 1995, 1996

</TABLE>
 
 Income Taxes
 
  The Company accounts for income taxes pursuant to Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS No. 109"),
which uses the liability method to calculate deferred income taxes. The
realization of deferred tax assets is based on historical tax positions and
expectations about future taxable income.
 
  The Company is included in the consolidated federal income tax return of
Synetic. The accompanying financial statements reflect income taxes as if the
Company filed a separate tax return.
 
 Foreign Currency Translation
 
  The financial statements and transactions of the Company's foreign
manufacturing facilities are maintained in their functional currency (Deutsche
mark and Pound sterling). The translation of foreign currencies into U.S.
dollars is performed for balance sheet accounts using current exchange rates
in effect at the balance sheet date and for revenue and expense accounts using
an average exchange rate for the period. The gains or losses resulting from
translation are included in stockholder's equity.
 
 Revenue Recognition
 
  Revenue is recognized upon product shipment, net of sales returns and
allowances.
 
 Net Income Per Share
 
  Net income per share is determined by dividing net income by the weighted
average number of shares of common stock outstanding during the period.
 
  In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128, "Earnings per Share" ("SFAS No.
128"). The new standard simplifies the computation of net income per share and
increases comparability to international standards. Under SFAS No. 128, basic

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)
 
income per share is computed by dividing net income by the weighted-average
number of common shares outstanding for the period. Diluted net income per
share reflects the potential dilution that could occur if securities or other
contracts to issue common stock were exercised or converted into common stock.
 
  The Company is required to adopt the new standard during fiscal 1998,
beginning with the December 31, 1997 interim consolidated financial
statements. All prior periods presented are required to be restated at that
time. The pronouncement is not expected to have a material impact on the
Company's reported earnings per share.
 
 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 amount of assets and liabilities and
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.
 
 Unaudited Interim Financial Information
 
  In the opinion of management, the unaudited consolidated financial
statements as of September 30, 1997 and for the three months ended September
30, 1996 and 1997, reflect all adjustments which are of a normal recurring
nature necessary to present fairly the Company's financial position, results
of operations and cash flows. Interim results of operations are not
necessarily indicative of results to be expected for the fiscal year.
 
(2) ACQUISITION:
 
 Interflo
 
  On February 10, 1997, the Company acquired the assets and assumed certain
liabilities of Interflo Technologies Inc. ("Interflo"), a manufacturing
operation located in College Point, New York for $11,340,000 in cash. At the
closing, $2,500,000 was placed in escrow as security against representations
and warranties contained in the purchase agreement. The escrow funds will be
released over a period of approximately one year. The acquisition was
accounted for using the purchase method with the purchase price being
allocated to assets acquired and liabilities assumed based on their appraised
fair values. Interflo's results of operations have been included in the
Company's financial statements since February 10, 1997.
 
  A summary of the purchase price is as follows (in thousands):

  In addition to the defined benefit pension plans discussed above, the
Company maintains a defined contribution profit sharing plan covering
substantially all of its employees. The Company matches a portion of
participant contributions with Synetic common stock. For the year ended June
30, 1997, Synetic issued 3,341 shares of common stock to the plan. For the
years ended June 30, 1995, 1996 and 1997, Company contributions were
approximately $59,100, $81,000 and $132,500, respectively.
 
(7) RELATED PARTY TRANSACTIONS:
 
 Tax sharing agreement
 
  The Company and Synetic intend to enter into a tax sharing agreement for the
periods during which the Company is included in the consolidated federal
income tax returns of Synetic. This agreement will provide, among other
things, for the Company to pay Synetic its allocable portion of the
consolidated federal income tax liability or receive refunds determined as if
the Company had filed separate federal income tax returns. The tax sharing
agreement will terminate on the last day on which the Company is included in
Synetic's federal consolidated income tax return.

(7) RELATED PARTY TRANSACTIONS--(CONTINUED)
 Services agreement
 
  The Company and Synetic intend to enter into a services agreement pursuant
to which Synetic will agree to provide the Company with services relating
primarily to financial analysis and tax and legal advice in connection with
the Company's operations and other technical services as required. The Company
will pay the actual costs of providing these services. Such costs will include
an allocable portion of the base compensation and other related expenses
(other than Synetic's benefit plans and employment agreements and
arrangements) of the officers of Synetic who serve as officers of the Company.
The service agreement will be terminable by either party upon 90 days' prior
written notice, at the end of any quarter. Allocated charges for normal,
recurring services provided by Synetic historically have not been material.
 
 Credit agreement
 
  Synetic intends to make available to the Company a revolving line of credit
to be used by the Company for the purpose of making acquisitions. Terms of
such line of credit, including the interest rate and security, if any, have
not been determined, and if such terms are not agreed upon by Synetic and the
Company, such line of credit may not be made available.
 
(8) STOCK OPTIONS:
 
  The Company expects to adopt stock options plans covering the employees,
officers and directors of the Company and its subsidiaries and certain
consultants, agents and key contractors of the Company. The exercise price for
such options will be equal to the initial public offering price.
 
(9) COMMITMENTS AND CONTINGENCIES:
 
 Leases

 Legal proceedings
 
  In the normal course of business, the Company is involved in various claims
and legal proceedings. While the ultimate resolution of these matters has yet
to be determined, the Company does not believe that their outcome will have a
material adverse effect on its financial position or results of operations.
 
  The Company has been named as one of many co-defendants in a number of
actions brought by recipients of silicone mammary implants. One of the pending
claims is styled as a purported class action. Certain of the actions against
the Company have been dismissed or settled by the manufacturer or insurance
carriers of the Company without material cost to the Company. The Company
believes its insurance coverage provides adequate coverage against liabilities
that could arise from actions or claims arising out of the Company's
distribution of implants. While the ultimate resolution of these matters has
yet to be determined, the Company does not believe that their outcome will
have a material adverse effect on its financial position or results of
operations.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
TO INTERFLO TECHNOLOGIES, INC.:
 
  We have audited the accompanying balance sheet of Interflo Technologies,
Inc. (a New York corporation) as of December 31, 1996 and the related
statements of income and retained earnings and cash flows for the year then
ended. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audit.
 
  We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Interflo Technologies,
Inc. as of December 31, 1996 and the results of its operations and its cash
flows for the year then ended in conformity with generally accepted accounting

 Property and Equipment
 
  Property and equipment are stated at cost. For financial reporting purposes,
depreciation is provided principally on the straight-line and double declining
balance methods over the estimated useful lives of the assets. Useful lives
range from 5 to 40 years for building improvements and from 3 to 7 years for
machinery and equipment and furniture and fixtures. For income tax purposes,
certain assets are depreciated using accelerated methods. Expenditures for
maintenance, repair and renewals of minor items are charged to operations as
incurred. Major improvements are capitalized.

        Total......................................................... $506,000
                                                                       ========
</TABLE>
 
 Income Taxes
 
  The Company operates under Subchapter S of the Internal Revenue Code and,
consequently, is not subject to Federal and certain state income taxes. The
stockholders include their pro rata share of the Company's income in their
personal income tax returns.
 
 Revenue Recognition
 
  Revenue is recognized upon product shipment, net of sales returns and
allowances.
 
 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 amount of assets and liabilities and
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.
 
(3) RELATED PARTY TRANSACTIONS:
 
  The Company paid monthly rent in the amount of $6,000 to its principal
stockholder and related individuals for factory, warehouse and office space.
This space was rented on a month-to-month basis, through September 30, 1996.
 
  The Company had a loan from an officer of $100,000 at December 31, 1996
bearing interest at 9% and payable on demand. The loan and accrued interest of
$121,000 were paid in full on February 11, 1997.
 
  The accrued distributions to shareholders at December 31, 1996 of $144,000
were paid on February 10, 1997.
 
  The Company sells marker nibs to Liqui-Mark which manufactures writing
instruments. Sales to Liqui-Mark were approximately $140,000 in 1996. At
December 31, 1996 the Company had a trade accounts receivable due from Liqui-
Mark of $34,000 and a payable resulting primarily from the spin-off of Liqui-
Mark of $193,000, which was subsequently paid.
 
  The Company has guaranteed a bank line-of-credit (amounting to $2,000,000)
for Liqui-Mark. As of December 31, 1996, $380,000 was outstanding under this
line-of-credit. The Company was released from this guarantee on January 29,
1997.

                         NOTES TO FINANCIAL STATEMENTS
 
(4) EMPLOYEE BENEFIT PLANS:
 
  The Company maintains a defined contribution savings plan (the "Savings
Plan") covering substantially all of its non-union employees. Participants
must be at least 21 years of age and have completed one year of service and
may contribute up to $9,500 of their earnings annually. The Savings Plan
allows for discretionary contributions to be made by the Company. For the year
ended December 31, 1996, no such contributions were made.
 
  The Company maintains a defined benefit pension plan (the "Pension Plan")
covering substantially all of its non-union employees. Pension Plan benefits
were frozen effective August 3, 1993 and the Company has proposed to terminate
the Pension Plan effective December 31, 1996. The Pension Plan sponsor has
applied for a favorable determination letter from the Internal Revenue Service
for the termination of the Pension Plan. The Company contribution for 1996 was
approximately $51,000.
 
  Effective July, 1993, a shareholder of the Company who is also a key
participant of the Pension Plan, elected to waive his right to a portion of
his benefits upon Pension Plan termination such that Pension Plan assets would
be sufficient to satisfy Pension Plan liabilities. After giving effect to this
waiver, plan assets are equal to the projected benefit obligation.
 
  In determining the projected benefit obligation, the weighted average
assumed discount rate was 6.5%.
 
(5) COMMITMENTS AND CONTINGENCIES
 
 Leases
 
  The Company leases office and warehouse space and automobiles under various
noncancellable operating leases. Rental expense was $250,000 for the year
ended December 31, 1996. The minimum aggregate rental commitments under
noncancellable leases, excluding renewal options, are as follows:

 Legal proceedings
 
  In the normal course of business, the Company is involved in various claims
and legal proceedings. While the ultimate resolution of these matters has yet
to be determined, the Company does not believe that their outcome will have a
material adverse effect on its financial position.

International Representatives, the "Representatives"). Subject to the terms
and conditions set forth in the U.S. Purchase Agreement, and concurrently with
the sale of 500,000 shares of Common Stock to the International Managers
pursuant to the International Purchase Agreement, the Company has agreed to
sell to the U.S. Underwriters, and the U.S. Underwriters severally have agreed
to purchase, an aggregate of 2,000,000 shares of Common Stock. The initial
public offering price per share and the underwriting discount per share of
Common Stock are identical under the International Purchase Agreement and the
U.S. Purchase Agreement.
 
  In each Purchase Agreement, the several International Managers and the
several U.S. Underwriters, respectively have agreed, subject to the terms and
conditions set forth in such Purchase Agreement, to purchase all the shares of
Common Stock offered hereby, if any are purchased. In the event of default by
an Underwriter, each Purchase Agreement provides that, in certain
circumstances, purchase commitments of the nondefaulting Underwriters may be
increased or the Purchase Agreement may be terminated. The sale of Common
Stock to the International Managers is conditioned upon the sale of shares of
Common Stock to the U.S. Underwriters.
 
  The International Managers and the U.S. Underwriters have entered into an
intersyndicate agreement (the "Intersyndicate Agreement") that provides for
the coordination of their activities. Pursuant to the Intersyndicate
Agreement, the International Managers and the U.S. Underwriters are permitted
to sell shares of Common Stock to each other for purposes of resale at the
initial public offering price set forth on the cover page of this Prospectus,
less an amount not greater than the selling concession. Under the terms of the
Intersyndicate Agreement, the U.S. Underwriters and any dealer to whom they
sell shares of Common Stock will not offer to sell or sell shares of Common
Stock to persons who are non-U.S. or non-Canadian persons or to persons they
believe intend to resell to persons who are non-U.S. or non-Canadian persons,
and the International Managers and any dealer to whom they sell shares of
Common Stock will not offer to sell or sell shares of Common Stock to U.S.
persons or Canadian persons or to persons they believe intend to resell to
U.S. persons or Canadian persons, except, in each case, for transactions
pursuant to the Intersyndicate Agreement.
 
  The International Representatives have advised the Company that the
International Managers propose initially to offer the shares of Common Stock
to the public at the initial public offering price set forth on the cover page
of this Prospectus, and to certain dealers at such price less a concession not
in excess of $     per

                   INTERNATIONAL PROSPECTUS--ALTERNATE PAGE
share of Common Stock. The International Managers may allow, and such dealers
may allow, a discount not in excess of $     per share of Common Stock on
sales to certain other dealers. After the initial public offering, the public
offering price, concession and discount may be changed.
 
  The Company and Synetic have agreed, subject to certain exceptions, not to,
directly or indirectly, (i) sell, grant any option to purchase or otherwise
transfer or dispose of any Common Stock or securities convertible into or
exchangeable or exercisable for Common Stock or file a registration statement
under the Securities Act with respect to the foregoing or (ii) enter into any
swap or other agreement or transaction that transfers, in whole or part, the
economic consequence of ownership of the Common Stock, without the prior
written consent of Merrill Lynch, for a period of 180 days after the date of
this Prospectus. The foregoing sentence shall not apply to (a) the shares of
Common Stock to be sold hereunder, (b) any shares of Common Stock issued by
the Company upon the exercise of an option or warrant or the conversion of a
security outstanding on the date hereof and referred to in this Prospectus,
(c) any shares of Common Stock issued or options to purchase Common Stock
granted pursuant to existing employee benefit or stock option plans of the
Company referred to in this Prospectus, (d) any shares of Common Stock issued
pursuant to any stock option plan for non-employee directors or (e) any shares
of Common Stock issued in connection with acquisitions or similar transactions
by the Company.
 
  The Company has granted an option to the International Managers, exercisable
for 30 days after the date of this Prospectus, to purchase up to an aggregate
of 75,000 additional shares of Common Stock at the initial public offering
price set forth on the cover page of this Prospectus, less the underwriting
discount. The International Managers may exercise this option only to cover
over-allotments, if any, made on the sale of the Common Stock offered hereby.
To the extent that the International Managers exercise this option, each
International Manager will be obligated, subject to certain conditions, to
purchase a number of additional shares of Common Stock proportionate to such
International Manager's initial amount reflected in the foregoing table. The
Company has also granted an option to the U.S. Underwriters, exercisable
within 30 days after the date of this Prospectus, to purchase up to an
additional 300,000 shares of Common Stock to cover over-allotments, if any, on
terms similar to those granted to International Managers.
 
  Prior to the Offerings, there has been no public market for the Common
Stock. The initial public offering price for the Common Stock was determined
by negotiation between the Company and the Representatives. The factors
considered in determining the initial public offering price, in addition to
prevailing market conditions, are price-earnings ratios of publicly traded
companies that the Representatives believe to be comparable to the Company,
certain financial information of the Company, the history of, and the
prospects for, the Company and the industry in which it competes, and an
assessment of the Company's management, its past and present operations, the
prospects for, and timing of, future revenues of the Company, the present
state of the Company's development, and the above factors in relation to
market values and various valuation measures of other companies engaged in
activities similar to the Company. There can be no assurance that an active
trading market will develop for the Common Stock or that the Common Stock will
trade in the public market subsequent to the Offerings at or above the initial
public offering price.
 
  The Company has agreed to indemnify the International Managers against
certain liabilities, including liabilities under the Securities Act of 1933,
as amended, or to contribute to payments the Underwriters may be required to
make in respect thereof.
 
  The International Representatives have advised the Company that the
Underwriters do not intend to confirm sales of Common Stock offered hereby to
any accounts over which they exercise discretionary authority.
 
  Until the distribution of the Common Stock is completed, rules of the
Securities and Exchange Commission may limit the ability of the Underwriters
and certain selling group members to bid for and purchase the Common Stock. As
an exception to these rules, the U.S. Representatives are permitted to engage
in certain transactions that stabilize the price of the Common Stock. Such
transactions consist of bids or purchases for the purpose of pegging, fixing
or maintaining the price of the Common Stock.
 
 
                                       3
<PAGE>
 
                   INTERNATIONAL PROSPECTUS--ALTERNATE PAGE
  If the Underwriters create a short position in the Common Stock in
connection with the Offerings (i.e., if they sell more shares of Common Stock
than are set forth on the cover page of this Prospectus), the U.S.
Representatives may reduce that short position by purchasing Common Stock in
the open market. The U.S. Representatives may also elect to reduce any short
position by exercising all or part of the over-allotment option described
above.
 
  The U.S. Representatives may also impose a penalty bid on certain
Underwriters and selling group members. This means that if the U.S.
Representatives purchase shares of Common Stock in the open market to reduce
the Underwriters' short position or to stabilize the price of the Common
Stock, they may reclaim the amount of the selling concession from the
Underwriters and selling group members who sold those shares as part of the
Offerings.
 
  In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher
than it might be in the absence of such purchases. The imposition of a penalty
bid might also have an effect on the price of a security to the extent that it
were to discourage resales of the security by purchasers in the Offerings.
 
  Neither the Company nor any of the U.S. Underwriters makes any
representation or prediction, however, as to the direction or magnitude of any
effect that the transactions described above may have on the price of the
Common Stock. In addition, neither the Company nor any of the Underwriters
makes any representation that the Representatives will engage in such
transaction or that such transactions, once commenced, will not be
discontinued without notice.
 
  Each International Manager has agreed that (i) it has not offered or sold,
and will not offer or sell, in the United Kingdom by means of any document any
shares of Common Stock other than to persons whose ordinary activities involve
them in acquiring, holding, managing or disposing of investments (as principal
or agent) for the purposes of their businesses or otherwise in circumstances
which have not resulted and will not result in an offer to the public in the
United Kingdom within the meaning of the Public Offers of Securities
Regulations 1995 (the "Regulations"), (ii) it has complied and will comply
with all applicable provisions of the Financial Services Act of 1986 and the
Regulations with respect to anything done by it in relation to the Common
Stock in, from or otherwise involving the United Kingdom and (iii) it has only
issued or passed on and will only issue or pass on to any person in the United
Kingdom any document received by it connection with the issuance of Common
Stock it that person is of a kind described in Article 11(3) of the Financial
Services Act 1986 (Investment Advertisements) (Exemptions) Order 1996 or is a
person to whom the document may otherwise lawfully be issued or passed on.
 
                                 LEGAL MATTERS
 
  The validity of the shares of Common Stock offered hereby will be passed
upon for the Company by Shearman & Sterling, New York, New York. Certain legal
matters will be passed upon for the Underwriters by Brown & Wood LLP, New
York, New York.
 
  The statements of law in this Prospectus under the Caption "Risk Factors--
Regulatory Requirements" and under the caption "Business--Regulation," are
based upon the opinion of Kegler, Brown, Hill & Ritter, Columbus, Ohio,
special regulatory counsel to the Company.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  The Company's Certificate of Incorporation and Bylaws set forth the extent
to which officers or directors of the Company may be indemnified against any
liabilities which they may incur. The general effect of such provisions is
that any person made a party to an action, suit or proceeding by reason of the
fact that he is or was a director or officer of the Company, or of another
corporation or other enterprise for which he served as such at the request of
the Company, shall be indemnified by the Company against expenses (including
attorney's fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by him in connection with such action, suit or proceeding,
to the full extent permitted under the laws of the State of Delaware. The
Company's Certificate of Incorporation and Bylaws extend such indemnification
to any employee who serves as an officer or director of any corporation at the
request of the Company. These provisions of the Company's Certificate of
Incorporation and Bylaws are not inclusive of any other indemnification rights
to which an officer or director may be entitled, whether by contract or
otherwise.
 
  The general effect of the indemnification provisions contained in Section
145 of the Delaware General Corporation Law is as follows: A director or
officer who, by reason of such directorship or officership, is involved in any
action, suit or proceeding (other than an action by or in the right of the
corporation) may be indemnified by the corporation against expenses (including
attorney's fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by him in connection with such action, suit or proceeding
if he acted in good faith and in a manner he reasonably believed to be in or
not opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, has no reasonable cause to believe that his
conduct was unlawful. A director or officer who, by reason of such
directorship or officership, is involved in any action or suit by or in the
right of the corporation may be indemnified by the corporation against
expenses (including attorneys' fees) actually and reasonably incurred by him
in connection with the defense or settlement of such action or suit if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation, except that no
indemnification may be made in respect of any claim, issue or matter as to
which he shall have been adjudged to be liable to the corporation unless and
only to the extent that a court of appropriate jurisdiction shall approve such
indemnification.
 
  The Company's Certificate of Incorporation provides that a director shall
not be personally liable to the Company or to any of its stockholders for
monetary damages for breach of fiduciary duty as a director of the
 
                                     II-1
<PAGE>
 
Company provided, however, that such provision shall not eliminate or limit
the liability of a director: (i) for breach of the director's duty of loyalty
to the Company or its stockholders, (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) pursuant to Section 174 of the Delaware General Corporation Law, or (iv)
for any transaction from which the director derived an improper personal
benefit.
 
  The Company intends to purchase director's and officers' liability insurance
for its executive officers and directors, assuming that such insurance is
available on commercially reasonable terms.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
  Other than the shares issued to Synetic upon the Registrant's incorporation

ITEM 17. UNDERTAKINGS.
 
  The undersigned Registrant hereby undertakes:
 
(1) To provide the underwriter at the closing specified in the underwriting
    agreement, certificates in such denominations and registered in such names
    as required by the underwriter to permit prompt delivery to each
    purchaser.
 
(2) For the purpose of determining any liability under the Act of 1933, the
    information omitted from the form of prospectus filed as part of this
    registration statement in reliance upon Rule 430A and contained in a form
    of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or
    497(h) under the Securities Act shall be deemed to be part of this
    registration statement as of the time it was declared effective.
 
(3) For the purpose of determining any liability under the Securities Act of
    1933, each post-effective amendment that contains a form of prospectus
    shall be deemed to be a new registration statement relating to the
    securities offered therein, and the offering of such securities at the
    time shall be deemed to be the initial bona fide offering thereof.
 
                                     II-2

  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 Registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as express
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.
