  The   % Convertible Subordinated Debentures ("Debentures") to be issued by
Synetic, Inc. ("Synetic" or the "Company") will be convertible, at the option
of the holder, at any time prior to maturity, unless previously redeemed or
repurchased, into shares of Common Stock, $.01 par value ("Common Stock"), of
the Company at a conversion price of $    per share of Common Stock (equivalent
to a conversion rate of       shares per $1,000 principal amount of
Debentures), subject to adjustment in certain events. The Common Stock is
traded on the Nasdaq National Market under the symbol "SNTC". On February 5,
1997 the last sale price of the Common Stock as reported on the Nasdaq National
Market was $46 7/8 per share.     
   
  Interest on the Debentures will be payable on August 15 and February 15 of
each year commencing August 15, 1997. The Debentures will be redeemable at any
time on or after February 15, 2000 at the option of the Company, in whole or in
part, at the redemption prices set forth herein, plus accrued and unpaid
interest. The Debentures are subordinated to present and future Senior Debt (as
defined herein) of the Company. As of the date of this Prospectus, the Company
had no Senior Debt outstanding. The Company is a holding company and,
accordingly, the Debentures will be effectively subordinated to all
indebtedness and other liabilities of subsidiaries of the Company. As of the
date of this Prospectus, the Company's subsidiaries had no indebtedness for
borrowed money. The Indenture contains no limitation on the amount of
indebtedness that may be incurred by the Company and its subsidiaries. The
Debentures are required to be repurchased at the option of the holder if a
Designated Event (as defined herein) occurs at 100% of the principal amount
thereof plus accrued and unpaid interest. See "Description of Debentures."     
 
  Up to $10,000,000 aggregate principal amount of the Debentures offered hereby
will be reserved for sale at the initial offering price to certain directors,
officers and employees of, and consultants to, the Company and its
subsidiaries.
   
  The Company intends to make application to list the Debentures on the Nasdaq
SmallCap Market.     
 
                                  ----------

EXCHANGE COMMISSION  OR ANY STATE SECURITIES COMMISSION NOR HAS  THE SECURITIES
 AND EXCHANGE COMMISSION  OR ANY  STATE SECURITIES COMMISSION  PASSED UPON THE

Business Area--Healthcare Communications," "--Government Regulation of
Healthcare," "--Reliance on Rapidly Changing Technology" and elsewhere and

risks may include product demand and market acceptance risks, the feasibility
of developing commercially profitable Internet healthcare products and
services, the effect of economic conditions, user acceptance, the impact of
competitive products, services and pricing and product development,
commercialization and technological difficulties. See "Risk Factors." Should

                                THE COMPANY     
 
  Synetic, Inc. operates in two principal lines of business, plastics
technologies and healthcare communications. Porex Technologies Corp. (together
with its subsidiaries, "Porex"), a wholly owned subsidiary of the Company,
designs, manufactures and distributes porous and solid plastic components and
products used in healthcare, industrial and consumer applications. Through
internal development efforts and its recent acquisitions, the Company is
building a new area of business relating to the use of Internet/Intranet
technology ("Internet technology") to expand and enhance the channels of
communication in the healthcare industry.
 
  Plastics Technologies Business. Porex's principal products, which incorporate
porous plastics, are used to filter, wick, drain, vent or control the flow of
fluids or gases. A large percentage of Porex's products are sold to other
manufacturers for incorporation into their products. The Company believes
Porex's principal strengths to be its manufacturing processes, quality control
and relationships with distributors of its proprietary health care products.
Porex's health care products include proprietary products manufactured and sold
under Porex's trade names. These products are sold for clinical and
medical/surgical use in hospitals, clinics, physicians' offices and
laboratories. Porex also manufactures and sells a line of plastic vials and
produces components made to the specifications of original equipment
manufacturers for incorporation into their healthcare products. Porex's
industrial and consumer products consist primarily of custom-manufactured
components made for manufacturers of industrial and consumer products. As a
result of the Company's development activities, the Company anticipates future
opportunities in several areas of Porex's business, which may include drug-
delivery systems, personal care products and micro-electronics.
   
  Healthcare Communications Business. The Company's objective in its healthcare
communications business is to use Internet technology to create an influential
interactive health services channel linking physicians with the payors,
suppliers and consumers of healthcare in order to control healthcare costs and
improve patient outcomes. A key element of the Company's strategy will be to
deploy via the public Internet and private     
 
                                       4
<PAGE>
 
   
Intranets, a suite of communications and transaction software that would enable
physicians and their staffs to perform high volume, routine transactions in a
uniform manner for all patients. The Company seeks to integrate payor-specific
content, such as benefit rules and treatment guidelines, with patient-specific
information at the point of care, thereby creating significant value for all
participants. There is no specific time frame for the Company's first
commercial introduction of its products and services, and the Company
anticipates that it will incur significant expenses in connection with the
development of these products and services. The provision of products and
services using Internet technology in the healthcare communications industry is
a developing business. For a discussion of the risks inherent in this
developing business, see "Risk Factors."     
   
  The Company recently completed the acquisition of two development stage
businesses in the healthcare communications area--Avicenna Systems Corp.
("Avicenna") and CareAgents, Inc. ("CareAgents"). See "Business--Healthcare
Communications Business--Recent Acquisitions."     
 
  Acquisition Program. The Company maintains an acquisition program and intends
to concentrate its acquisition efforts in businesses which are complementary to
the Company's healthcare communications strategy. This emphasis, however, is
not intended to limit in any manner the Company's ability to pursue acquisition
opportunities in other healthcare-related businesses or in other industries.
See "Risk Factors--Acquisition Program" and "Business--Acquisition Program."

                                 RISK FACTORS
 
  Prior to making an investment decision with respect to the Debentures
offered hereby, prospective investors should carefully consider the specific
factors set forth below, together with all of the other information appearing
herein, in light of their particular investment objectives and financial
circumstances.
 
NEW BUSINESS AREA--HEALTHCARE COMMUNICATIONS
 
  Initial Development Phase. The Company is in the initial development phase
of offering products and services to provide inter-enterprise connectivity to
payors and providers in the healthcare industry. The provision of products and
services using Internet technology in the healthcare communications industry
is a developing business. There is no specific time frame for the Company's
first commercial introduction of its products and services, and the Company
anticipates that it will incur significant expenses in connection with the
development of these products and services. There can be no assurance that
these products and services will be successfully developed by the Company.
Avicenna, the Company's first acquisition in this area, has operated at a loss
since its inception two years ago, and as of November 30, 1996 had an
unaudited accumulated deficit of approximately $3,100,000. CareAgents, the
Company's second acquisition in this area, founded in 1996, is a start-up
company with a very limited operating history. The Company is pursuing the
development of its healthcare communications business through the use of its
internal resources as well as pursuing the acquisition of complementary
businesses. The Company anticipates that it may enter into acquisitions, joint
ventures, strategic alliances or other business combinations. These
transactions may materially change the nature and scope of this business.
There can be no assurance that the Company will succeed in consummating such
transactions or that such transactions will ultimately provide the Company
with the ability to offer the products and services described.
 
  Uncertainty of Market Acceptance. As is typical in a developing business,
demand and market acceptance for new and unproven products and services are
subject to a high level of uncertainty. Achieving market acceptance for the
Company's products and services will require substantial marketing efforts and
expenditure of significant funds to create awareness and demand by
participants in the healthcare industry. No assurances can be given that the
Company's effort in establishing such products and services will be
successful, that the Company will be able to succeed in positioning its
services as a preferred method for healthcare communications, that there will
be significant market acceptance for its products and services or that any
pricing strategy developed by the Company will be economically viable or
acceptable to the market.
 
  Expected Losses. Synetic expects to continue to incur significant research
and development expenses and incur additional operating losses in connection
with its healthcare communications business until the products and services
are successfully developed and marketed. The rate of aggregate expenditures at
Avicenna and CareAgents immediately prior to their acquisition was
approximately $1,600,000 per quarter. Research and development expenses
relating to Avicenna may be materially greater in the future than current
amounts until the Company successfully develops and markets these products and
services. Synetic anticipates, however, that such research and development
expenses will not exceed $2,500,000 per fiscal quarter for the third and
fourth quarters of the current fiscal year ending June 30, 1997 and will not
result in net losses for Synetic on a consolidated basis for the current
fiscal year (excluding the non- recurring charges for purchased research and
development costs relating to the acquisition of Avicenna and CareAgents; see
"Business--Healthcare Communications Business"), or for either of the fiscal
quarters ending March 31, 1997 or June 30, 1997. There can be no assurance as
to when, and to what extent, if any, the healthcare communications business of
the Company will become profitable.
 
GOVERNMENT REGULATION OF HEALTHCARE
 
  Participants in the healthcare industry are subject to extensive and
frequently changing regulation under numerous laws administered by
governmental entities at the federal, state and local levels. Many current
laws and regulations, when enacted, did not anticipate the methods of
healthcare communication under development by the Company. The Company
believes, however, that these laws and regulations will nonetheless be applied
to the Company's healthcare communications business. Accordingly, the
Company's healthcare communications business may be affected by current
regulations as well as future regulations specifically targeted to this new
segment of the healthcare industry.
 
                                       9
<PAGE>
 
  Current laws and regulations which may affect the healthcare communications
business include (i) the regulation of confidential patient medical record
information, (ii) laws relating to the electronic transmission of
prescriptions from physicians' offices to pharmacies, (iii) regulations
governing the use of software applications in the diagnosis, cure, treatment,
mitigation or prevention of disease and (iv) laws or regulations relating to
the relationships between or among healthcare providers. The Company expects
to conduct its healthcare communications business in substantial compliance
with all material federal, state and local laws and regulations governing its
operations. However, the impact of regulatory developments in the healthcare
industry is complex and difficult to predict, and there can be no assurance
that the Company will not be materially adversely affected by existing or new
regulatory requirements or interpretations.
 
RELIANCE ON RAPIDLY CHANGING TECHNOLOGY
 
  All businesses which rely on Internet technology, including the healthcare
communications business described herein, are subject to rapid technological
change, changing customer needs, frequent new product introductions and
evolving industry standards. In addition, as the communications, computer and
software industries continue to experience rapid technological change, the
Company must be able to quickly and successfully adapt its products and
services so that they adapt to such changes. There can be no assurance that
the Company will not experience difficulties that could delay or prevent the
successful development and introduction of its healthcare communications
products and services. The Company's inability to respond to technological
changes in a timely and cost- effective manner could have a material adverse
effect on the Company's business, financial condition and results of
operations. Moreover, there can be no assurance that technologically superior
products and services will not be developed by competitors, or that any such
products and services will not have an adverse effect upon the Company's
operating results.
 
COMPETITION IN HEALTHCARE COMMUNICATIONS
 
  The Company is not aware of any business which currently provides the scope
and breadth of the healthcare communications products and services currently
being developed by the Company. However, various companies including, but not
limited to, certain physician office management information systems companies,
EDI/data networking companies, online medical information service companies,
and systems integration companies, some of which may have greater resources
than the Company, have announced that they are developing a combination of one
or more of these products and services. There can be no assurance that such
companies will not develop and successfully market the healthcare
communications products and services described herein in a manner which would
have a material adverse effect on the Company. See "Business--Healthcare
Communications Business--Business Strategy."
 
RISKS OF PRODUCT DEVELOPMENT; PROPRIETARY RIGHTS
 
  The Company's future success and ability to compete in the healthcare
communications business may be dependent in part upon its proprietary rights
to products and services which it develops. The Company may rely on a
combination of copyrights, trademarks and trade secrets and contractual
restrictions to protect its content and technology and on similar proprietary
rights of its content and technology providers. There can be no assurance that
the steps taken by the Company or such providers would be adequate to prevent
misappropriation of their respective proprietary rights or that the Company's
competitors will not independently develop content or technology that are
substantially equivalent or superior. In addition, there can be no assurance
that licenses for any intellectual property of third parties that might be
required for the Company's products or services would be available on
commercially reasonable terms or at all. Although the Company intends to take
steps to insure that it is not infringing the proprietary rights of any third
parties, there can be no assurance that patent infringement or other claims
will not be asserted against the Company or one of its content or technology
providers or that such claims will not be successful. The Company could incur
substantial costs and diversion of management resources with respect to the
defense of any such claims. Furthermore, parties making such claims against
the Company or a content or technology provider could secure a judgment
awarding substantial damages, as well as injunctive or other equitable relief
which could effectively block the Company's ability to provide products or
services in certain of its markets. Such a judgment could have a material
adverse effect on the Company's business, financial condition and results of
operations.

GOVERNMENT REGULATION OF POREX
 
  Porex manufactures and distributes certain medical/surgical devices, such as
plastic and reconstructive surgical implants and tissue expanders, which are
subject to government regulations, including approval procedures instituted by
the Food and Drug Administration. Future healthcare products may also be
subject to such regulations and approval processes. Compliance with such
regulations 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, if ever. See "Business--Porex--Regulation" in the
1996 10-K.
 
POTENTIAL LIABILITY RISK AND AVAILABILITY OF INSURANCE
 
  The products sold by the Company expose it to potential risk for product
liability claims particularly with respect to Porex's life sciences, clinical
and surgical products. The Company believes that Porex 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. In 1994, Porex was notified that its 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 silicone
mammary implants. However, Porex has exercised its right 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. See
"--Certain Litigation." Porex has renewed its insurance coverage with the same
carrier for other liability claims. Although Porex has been able to obtain
adequate insurance coverage at an acceptable cost in the past 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 be adequately protected
by such indemnification. See "Business--Porex--Health Care Products" and
"Legal Proceedings--Mammary Implant Litigation" in the 1996 10-K.
 
CERTAIN LITIGATION
 
  During the year ended June 30, 1988, Porex began distributing 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 had ceased offering
implants for sale prior to the recall date. 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 totals 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. One of the pending
actions, Donna L. Turner v. Porex Technologies Corporation, et al., is styled
as a class action. 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 January 31, 1997, 57 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 January 31, 1997, 217 actions and 34
out-of-court claims were pending against Porex. Of the 217 actions, 100
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 the fiscal year ended June 30, 1996 was significantly
lower than the number of claims made during the fiscal year ended June 30,
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.

  In 1994, Porex was notified that its 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. However,
Porex has exercised its right, under such policy, 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 which by its terms would expire December
31, 1997. However, Porex expects to purchase further extended reporting period
coverage from the excess insurers to the extent such coverage is reasonably
available. The Company believes that its present coverage, together with
Porex's 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.
 
  The Company believes that Porex 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.
 
ACQUISITION PROGRAM
 
  The Company maintains an acquisition program and intends to concentrate its
acquisition efforts on businesses which are complementary to the Company's
healthcare communications strategy, but such emphasis is not intended to limit
in any manner the Company's ability to pursue acquisition opportunities in
other healthcare-related businesses or in other industries. The Company
anticipates that it may enter into acquisitions, joint ventures, strategic
alliances or other business combinations. These transactions may materially
change the nature and scope of the business. Any transactions will be limited,
as required by agreements to which the Company is a party, to areas of
business that would not be competitive with certain businesses of Merck & Co.,
Inc. and its subsidiaries or with the Institutional Pharmacies Business (as
defined in "Business--Certain Corporate History"). See "Business--Certain
Corporate History" below and "Certain Relationships and Related Transactions"
in the 1996 10-K. Although management of the Company will endeavor to evaluate
the risks inherent in any particular transaction, there can be no assurance
that the Company will properly ascertain all such risks. In addition, no
assurances can be given that the Company will succeed in consummating any such
transactions, that such transactions will ultimately provide the Company with
the ability to offer the products and services described or that the Company
will be able to successfully manage or integrate any resulting business.
   
  The success of the Company's acquisition program will depend on, among other
things, the availability of suitable candidates, the availability of funds to
finance transactions, and the availability of management resources to oversee
the operation of resulting businesses. Financing for such transactions may
come from several sources, including, without limitation, (a) cash and cash
equivalents on hand and marketable securities and (b) proceeds from the
incurrence of indebtedness or the issuance of additional Common Stock,
preferred stock, convertible debt or other securities. The issuance of
additional securities, including Common Stock, could result in substantial
dilution of the percentage ownership of the stockholders of the Company at the
time of any such issuance, could result in substantial dilution of the
Company's earnings per share and could adversely affect the prevailing market
price for the Debentures. The proceeds from any financing may be used for
costs associated with identifying and evaluating prospective candidates, and
for structuring, negotiating, financing and consummating any such transactions
and for other general corporate purposes. The Company does not intend to seek
stockholder approval for any such transaction or security issuance unless
required by applicable law or     
 
                                      12
<PAGE>
 
regulation. Although Mr. Martin J. Wygod, Chairman of the Board of the
Company, has indicated his intention to assist the Company in its acquisition
program by bringing opportunities for potential transactions to the Company
and to assist the Company in negotiating such transactions and in seeking
financing in the event any such transaction were to be financed by the
Company, he is not an officer or an employee of the Company nor is he required
pursuant to any contractual obligation to provide such support or assistance.
See "Business--Acquisition Program."
 
DISCRETIONARY USE OF PROCEEDS
 
  The Company currently intends to use the net proceeds from the sale of the
Debentures for general corporate purposes, which may include acquisitions. The
Company's management has broad discretion with respect to the specific
application of the net proceeds of this Offering.
 
HOLDING COMPANY STRUCTURE
 
  The Company is a holding company that has no significant operations other
than those incidental to its ownership of its Porex and Avicenna subsidiaries.
It is anticipated that future acquisitions will be operated through
subsidiaries. As a holding company, to the extent that the Company would
require funds to meet its debt service and other obligations and such funds
are not available at the holding company level, the Company would be dependent
on dividends or other intercompany transfers of funds from Porex and Avicenna
or such other subsidiaries. Claims of creditors of the Company's subsidiaries,
including trade creditors, generally will have priority as to the assets of
such subsidiaries over the claims of the Company and the holders of the
Company's indebtedness, including the Debentures. The indenture pursuant to
which the Debentures will be issued will not restrict borrowing at either the
Company or the subsidiary level, including borrowings in connection with the
Company's acquisition program. See "Description of Debentures."
 
SUBORDINATION OF DEBENTURES
 
  The Debentures will be subordinated to existing and future Senior Debt of
the Company. As of the date of this Prospectus, the Company had no Senior Debt
outstanding. The company is a holding company and, accordingly, the Debentures
will be effectively subordinated to all existing and future liabilities of the
Company's subsidiaries. As of the date of this Prospectus, the Company's
subsidiaries had no indebtedness for borrowed money. Upon any distribution of
assets of the Company upon any dissolution, winding up, liquidation or
reorganization, the payment of the principal of, premium, if any and interest
on the Debentures will be subordinated to the extent provided in the Indenture
in right of payment to the prior payment in full of all Senior Debt. By reason
of this provision, in the event of the Company's dissolution or insolvency,
holders of Senior Debt may receive more, ratably, and holders of the
Debentures may receive less, ratably, than the other creditors of the Company.
See "Description of Debentures--Subordination."
 
ABSENCE OF AN ESTABLISHED MARKET FOR THE DEBENTURES
   
  Prior to the offering of the Debentures, there has been no public trading
market for the Debentures. Although the Company intends to make application to
list the Debentures on the Nasdaq SmallCap Market, there can be no assurance
that an active public market for the Debentures will develop or, if a public
market develops, that the market price will exceed the public offering price
set forth on the covering page of this Prospectus. If an active public trading
market for the Debentures does not develop, the market prices and liquidity of
the Debentures may be adversely affected. Because the Debentures are
convertible into Common Stock, the prices at which the Debentures trade in the
market will likely be affected by the price of the Company's Common Stock.

SHARES AVAILABLE FOR FUTURE SALE
 
  The 5,061,857 Wygod Shares (as defined in "Business--Certain Corporate
History") are "restricted securities," within the meaning of Rule 144
promulgated pursuant to the Securities Act ("Rule 144"), subject to the volume
restrictions of Rule 144 but for which the two-year holding period has
expired. In addition, as more fully set forth in "Certain Relationships and
Related Transactions" in the 1996 10-K, the Wygod Shares are subject to
certain restrictions on transfer. Upon expiration of such restrictions, SN
Investors, L.P. ("SN Investors") may be able to sell without registration
under the Securities Act the number of such shares permitted under Rule 144.
The Company has granted certain demand registration rights to Mr. Wygod with
respect to the Wygod Shares that are assignable to SN Investors. Any sales by
SN Investors pursuant to Rule 144 or such registration rights could have a
material adverse effect on the prevailing market price for the Common Stock.
See "Business--Certain Corporate History" and "Description of Capital Stock--
Shares Eligible for Future Sale."
   
  As of January 31, 1997, the Company has reserved an aggregate of 7,001,156
shares of Common Stock for issuance pursuant to stock option agreements and
stock option plans and an additional 250,000 shares for issuance upon the
exercise of warrants exercisable after December 23, 1998. The sale of a
substantial amount of such additional shares of Common Stock following their
issuance could have a material adverse effect on the market price of the
Common Stock.     
 
CERTAIN ANTITAKEOVER EFFECTS
   
  Provisions in the Certificate of Incorporation of the Company relating to a
staggered Board of Directors, super-majority requirements and delegation of
rights to issue Preferred Stock may have the effect not only of discouraging
tender offers or other stock acquisitions but also of deterring existing
stockholders from making management changes. See "Description of Capital
Stock--Common Stock." In addition, the requirement that the Company repurchase
the Debentures, at the option of the holder, upon the occurrence of a
Designated Event may, in certain circumstances, make more difficult or
discourage a takeover of the Company. See "Description of Debentures--
Repurchase at Option of Holder upon Occurrence of a Designated Event."

                             USE OF PROCEEDS     
 
  The net proceeds from the sale of the Debentures are estimated to be
approximately $    ($    if the Underwriter's over-allotment option is
exercised in full). The Company currently intends to use the net proceeds for
general corporate purposes, which may include 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.
Pending the use of the net proceeds as described above, the Company intends to
maintain the net proceeds in short-term or demand interest-bearing instruments
or accounts. See "Prospectus Summary--The Company" and "Risk Factors--The
Acquisition Program."

                                   BUSINESS
 
GENERAL
 
  Synetic, Inc. operates in two principal lines of business, plastics
technologies and healthcare communications. Porex Technologies Corp. (together
with its subsidiaries, "Porex"), a wholly owned subsidiary of the Company,
designs, manufactures and distributes porous and solid plastic components and
products used in healthcare, industrial and consumer applications. Porex's
principal products, which incorporate porous plastics, are used to filter,
wick, drain, vent or control the flow of fluids or gases. Through its recently
acquired wholly owned subsidiary, Avicenna Systems Corporation, the Company
has directed its efforts in a new area of business relating to the use of
Internet technology to expand the channels of communication in the healthcare
industry. The creation of these new channels is intended to benefit providers
and payors of healthcare services by improving the quality of patient care,
securing appropriate utilization of healthcare services, reducing
administrative costs and enforcing benefit plan guidelines.
 
PLASTICS TECHNOLOGIES BUSINESS
 
 General
 
  Porex designs, manufactures and distributes porous and solid plastic
components and products used in healthcare, industrial and consumer
applications. Porous plastics are permeable plastic structures having omni-
directional (i.e., porous in all directions to the flow of fluids or gases)
interconnecting pores. Porous plastics are manufactured by Porex 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). Porous plastic materials can be
molded from several thermoplastic raw materials and are produced by Porex at
its own manufacturing facilities as fabricated devices, custom-molded shapes,
sheets, tubes or rods depending on application or manufacturer specifications.
Porex also purchases for resale through its distribution channels certain
products which are complementary to its manufactured product lines. As a
result of the Company's development activities, the Company anticipates future
opportunities in several areas of Porex's business, which may include drug-
delivery systems, personal care products and micro-electronics.
 
 Healthcare Products
 
  Porex's proprietary products for life sciences, clinical and surgical
applications include blood serum filters, blood tube closure devices, pipette
tips and a line of medical/surgical products designed primarily for use in
plastic and reconstructive surgery and maxillofacial surgery. Porex also
manufactures and sells a line of plastic vials and produces components made to
the specifications of original equipment manufacturers for incorporation into
their healthcare products.
 
  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. The filters allow the serum
to pass through while blocking passage of particulate materials. Analysis of
the serum provides specific information as to a patient's health. Porex also
manufactures a line of closure devices that are used with blood serum filters
and tubes. In response to health concerns regarding the handling of human
blood, new blood testing equipment has been developed by other companies which
does not require filtered blood serum for analysis, or which eliminates the
need for handling of blood serum by medical personnel. The use of such new
equipment has reduced the demand for Porex's current line of blood serum
filters.
 
  Porex produces a line of filtered and non-filtered pipette tips which are
used for dispensing fluids, primarily in industrial research laboratories.
 
  Porex's surgical products are marketed primarily to surgeons who specialize
in plastic and reconstructive surgery and maxillofacial surgery. The product
line includes MEDPOR(R) Surgical Implant material, which is
 
                                      17
<PAGE>
 
polymeric biomaterial used for craniofacial reconstruction and augmentation,
and TLS(R) Surgical Drainage Systems for small wound sites. Porex also markets
TLS(R) Surgical Marker pens to mark the areas of proposed surgical incision.
Porex manufactures MEDPOR(R) Surgical Implant material and distributes, and in
some cases assembles, the other items in its surgical product line.
 
  Porex manufactures various porous plastic components that it sells to other
healthcare product manufacturers for incorporation into their finished
products. These porous plastics are used to vent or diffuse gases or fluids
and are used as membrane supports in other manufacturers' products. The
components include (i) disks used to support membranes, modules and other
filtration devices, (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) a porous disk used in pipette tips to prevent the fluid to be pipetted
from passing into the pipette instrument, and (iv) an oxygen diffuser, which
is typically used in oxygen therapy equipment to humidify oxygen.
 
  Porex manufactures and sells a full line of plastic vials for
pharmaceuticals. 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. These
products are custom designed and produced to satisfy individual customer
specifications.
 
 Industrial Products
 
  Porex manufactures a variety of custom porous plastic components for
industrial applications. These components are produced as molded shapes, and
in sheets, tubes and rods, individually designed to customer specifications as
to size, rigidity, porosity and other needs.
 
  Porex's industrial applications include (i) automotive products, primarily
porous plastic vents used in automobile batteries as a flame arrester, (ii)
wastewater treatment filter support media, (iii) filters to remove particulate
matter, oil and water residues from compressed air lines, (iv) silencers and
mufflers to reduce sound levels produced by compressed air exhaust, and (v)
products for facilitating the movement of powdered materials. Porex also
manufactures a large variety of highly specialized plastic components to meet
specific applications for manufacturers.
 
 Consumer Products
 
  Porex manufactures a line of porous plastic components used in a variety of
home and office products and appliances. 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. Porex produces a
variety of porous plastic filters used in home water filters and conditioners.
The filters are used for particle and sediment removal through devices
attached to a sink or faucet. The Company also manufactures filters
incorporating activated carbon used to reduce chlorine levels in drinking
water thereby improving its taste and odor. Porex's porous plastic components
are used in health and beauty aid products (such as deodorant and fragrance
applicators).
 
HEALTHCARE COMMUNICATIONS BUSINESS
 
 Industry Background
 
  The U.S. healthcare industry continues to undergo rapid and dramatic change.
According to industry sources, current healthcare expenditures now exceed $1
trillion and represent approximately 14% of gross domestic product. The aging
of the U.S. population should continue to fuel growth in aggregate costs since
older Americans consume more healthcare services. Increasing concern over the
rising cost of healthcare in the United States has caused a shift away from
fee-for-service indemnity plans into health maintenance organizations (HMOs)
and other managed healthcare benefit plans. This trend has been accompanied by
the emergence of
 
                                      18
<PAGE>
 
various managed care techniques that such organizations use to control costs.
These techniques include, but are not limited to, negotiated price discounts
with healthcare providers, restrictions on physician access, increased
emphasis on preventative healthcare services, utilization review/case
management functions, and shifting the economic risk for the delivery of care
to providers through alternative reimbursement models, such as capitation and
fixed fees. Management believes that while these techniques have initially
been helpful in containing healthcare costs, managed care organizations need
an effective means of communicating with physicians and other healthcare
providers at the time of care delivery in order to further reduce
administrative and medical costs. The fragmented healthcare information
infrastructure in place today makes it difficult for managed care
organizations to effectively communicate and implement benefit rules and care
guidelines.
 
  Healthcare providers are also facing new pressures in this changing practice
environment. Physicians in general have experienced declining incomes and
increased levels of financial risk due to the rise of managed care. It is
management's belief that a physician's ability to absorb price decreases,
comply with plan guidelines and manage risk is frustrated by a lack of
automation and efficient communication in managed care processes and by payor
fragmentation. With approximately 80% of healthcare expenditures under
physician control and a significant portion of their time being spent on
administrative tasks, an effective channel of communication at the point of
care should provide measurable benefits to both payors and providers.
Management believes that giving providers access to detailed clinical and
administrative information in a way that is easy to use, consistent among
payors, and compatible with existing information systems is critical to
achieving further cost containment and improved patient care.
 
  The growth of Internet technology has established the opportunity for a low-
cost solution to inter-enterprise connectivity while preserving investment in
legacy systems. Internet technology permits the integration of systems across
various healthcare constituencies regardless of differences in architectures,
platforms or operating systems. Technological improvements have converged with
changes in the healthcare industry in a way which enables new products and
services, that were previously not possible, to be offered. See "Risk
Factors--Reliance on Rapidly Changing Technology."
 
 Business Strategy
   
  The Company's objective is to use Internet technology to create an
influential interactive health services channel linking physicians with the
payors, suppliers and consumers of healthcare in order to control healthcare
costs and improve patient outcomes. The Company expects to provide a content-
neutral, application rich utility thereby creating a channel which serves as a
conduit for the private content that any healthcare organization wishes to
communicate to physicians and other healthcare providers. Key elements of the
Company's strategy are to:     
   
 . Accelerate the development of a low-cost service to provide a suite of
  communication, information and transaction functions by integrating the
  Avicenna and CareAgents acquisitions (see "Recent Transactions"). Avicenna's
  business plan has been to develop and market Intranets to managed care
  plans, hospitals and physician groups. These Intranets will provide
  organizations the ability to quickly link physicians, providers and
  suppliers to a vast array of public reference material, proprietary plans
  rules, treatment guidelines and managed care transactions. In addition,
  CareAgents had been developing complementary software focused on providing
  physicians, health plans and patients tools to conduct clinical commerce via
  the public Internet and private Intranets. Since these services are intended
  to enable physicians to perform high volume, routine transactions in a
  uniform manner for all patients, the Company believes that these services
  will help physicians practice medicine more efficiently in today's managed
  care environment.     
 
 . Differentiate this suite of client server applications by its ability to
  allow physicians and their staffs to conduct not only administrative but
  also clinical transactions. These transactions would include but not be
  limited to eligibility verification, referrals, treatment authorizations,
  claims and encounter submissions, as well as laboratory test submission and
  reporting, prescription writing, drug utilization and formulary review, and
 
                                      19

  pharmacy routing. The ability to integrate payor-specific content such as
  benefit rules and care guidelines with patient-specific information at the
  time of treatment will significantly enhance the delivery of high quality,
  cost effective care.
 
 . Contract with managed care organizations, integrated health delivery
  systems, pharmacy benefit managers and clinical laboratories so that they
  might provide physicians with access to their proprietary benefit plan
  information and treatment guidelines as well as their administrative and
  managed care processes. Management believes that this new channel of
  communications will allow each of the parties to (i) leverage their existing
  healthcare information systems infrastructure, (ii) to integrate their
  proprietary rules and guidelines with transactions, and (iii) to realize
  administrative and medical resource savings while improving provider
  relationships and streamlining managed care processes. The Company
  anticipates it will be compensated by such parties as a result of the value
  created.
 
  The Company is not aware of any business which currently provides the scope
and breadth of the services described above. However, various companies
including, but not limited to, certain physician office management information
systems companies, EDI/data networking companies, online medical information
service companies, and systems integration companies, some of which may have
greater resources than the Company, have announced that they are developing a
combination of one or more of these products and services. There can be no
assurance that such companies will not develop and successfully market the
healthcare communications products and services described herein in a manner
which would have a material adverse effect on the Company. The Company's
management believes that its advantage lies in its prior experiences and
backgrounds in the healthcare industry which have resulted in a unique
understanding of the economics underlying the transaction capabilities it
seeks to provide. Through direct experience, the Company's management also
understands the difficulties faced by healthcare payors and providers in
adopting and promoting a standard communication utility. This knowledge base
combined with the technology resources described below in "Recent
Acquisitions" gives the Company a strong platform for executing its business
strategy.
 
 Recent Acquisitions
 
  The Company recently completed two acquisitions in the healthcare
communications area. On December 24, 1996, the Company acquired Avicenna, a
privately held development stage company located in Cambridge, Massachusetts.
Avicenna's business plan has been to market and build Intranets for managed
care organizations, hospitals and physician groups. Avicenna's controlled
access Intranet systems are designed to allow payors and providers to exchange
transactional, procedural, patient outcomes and educational information. On
January 23, 1997, the Company acquired privately held CareAgents to add
management resources with expertise in large-scale commercial clinical
applications, medicine and information technology. CareAgents was an early
development stage company focussed on developing Internet clinical commerce
applications. The Company is presently integrating these acquisitions and
expects them to be the foundation on which its business strategy will be
developed. Avicenna and CareAgents have, collectively, approximately 50
employees.
 
  The Company acquired all of Avicenna's outstanding equity and indebtedness
(including stock options) for shares of Synetic Common Stock with a market
value of $30.5 million. As additional consideration, the Company issued to
certain of the sellers nontransferable warrants covering 250,000 shares of
Synetic Common Stock, exercisable after December 23, 1998 at a price of $54.50
per share. Synetic acquired CareAgents for shares of Synetic Common Stock with
a market value of $5 million.
   
  During the quarter ended December 31, 1996, the Company recorded a non-
recurring charge of $28,600,000 relating to purchased research and development
costs in conjunction with its acquisition of Avicenna. Under generally
accepted accounting principles, the amount of purchase price allocable to
purchased research and development costs is required to be expensed
immediately after the acquisition. The Company expects to record a non-
recurring charge in the quarter ended March 31, l997 relating to purchased
research and development costs in conjunction with its acquisition of
CareAgents in January l997. While the exact amount of the charge is not yet
determinable, the Company does not expect this charge to exceed $3 million.
    
                                      20
<PAGE>
 
  As a result of the acquisition of Avicenna and CareAgents, the Company
expects to incur significant research and development expenses and incur
additional operating losses in connection with this new area of business until
the products and services are successfully developed or marketed. There can be
no assurances that the products or services will be successfully developed or
marketed. The rate of aggregate expenditures at Avicenna and CareAgents
immediately prior to their acquisition was approximately $1,600,000 per
quarter. Research and development expenses may be materially greater in the
future than current amounts until the Company successfully develops its
products and services. The Company, however, anticipates that such research
and development expenses will not exceed $2,500,000 per fiscal quarter for the
third and fourth quarters for the fiscal year ending June 30, 1997 and will
not result in net losses for the current fiscal year (excluding the non-
recurring charges for purchased research and development costs relating to the
acquisition of Avicenna and CareAgents) or for either of the fiscal quarters
ending March 31, l997 or June 30, l997.
 
  The Company is pursuing the development of its healthcare communications
business through the use of its internal resources as well as pursuing the
acquisition of complementary businesses. The Company anticipates that it may
enter into acquisitions, joint ventures, strategic alliances or other business
combinations. These transactions may materially change the nature and scope of
this business. There can be no assurance that the Company will succeed in
consummating such transactions or that such transactions will ultimately
provide the Company with the ability to offer the products and services
described.
 
ACQUISITION PROGRAM
 
  The Company maintains an acquisition program and intends to concentrate its
acquisition efforts in businesses which are complementary to the Company's
healthcare communications strategy. This emphasis, however, is not intended to
limit in any manner the Company's ability to pursue acquisition opportunities
in other healthcare-related business or in other industries. See "Risk
Factors--Acquisition Program" and "Business--Healthcare Communications
Business--Recent Acquisitions."
 
CERTAIN CORPORATE HISTORY
 
  Prior to June 28, 1989, the date of the initial public offering of the
Company, the Company was an indirect wholly owned subsidiary of Medco
Containment Services, Inc. ("Medco"). Thereafter, the Company became a
publicly held, partially owned subsidiary of Medco. Medco provided healthcare
cost containment services, principally managed prescription drug programs, to
benefit plan sponsors. On November 18, 1993, Medco was acquired by Merck &
Co., Inc. ("Merck") in a merger transaction, and as a result, the Company
became an indirect, partially owned subsidiary of Merck. Merck is a
pharmaceutical manufacturer. Until December 14, 1994, the Company's operations
consisted of Porex and a group of subsidiaries that provided institutional
pharmacy services (the "Institutional Pharmacies Business").
   
  On December 14, 1994, the Company consummated certain transactions pursuant
to which: (1) the Company sold the Institutional Pharmacies Business to
Pharmacy Corporation of America, an indirect wholly owned subsidiary of
Beverly Enterprises, Inc. (such sale is referred to herein as the
"Divestiture"), for approximately $107,300,000; (2) the Company purchased
5,268,463 shares of its Common Stock from Merck for an aggregate purchase
price of $37,764,019, pursuant to the Purchase and Sale Agreement, dated as of
May 24, 1994, between the Company and Merck; and (3) SN Investors, a limited
partnership the general partner of which is SYNC, Inc. (the "General
Partner"), whose sole stockholder is Mr. Wygod, purchased 5,061,857 shares of
Common Stock (the "Wygod Shares") from Merck for an aggregate purchase price
of $36,283,079, pursuant to an assignment by the Company of the right to
purchase such shares from Merck contained in an Investment Agreement between
Mr. Wygod and the Company, dated as of September 13, 1994 (the "Investment
Agreement"). The Investment Agreement also governs the terms and conditions
under which the Wygod Shares will be held by Mr. Wygod and his permitted
assignees and transferees. SN Investors has agreed to be bound by all of the
restrictions and obligations applicable to Mr. Wygod under the Investment
Agreement. The purchases of shares of Common Stock from Merck by the Company
and SN Investors are hereinafter referred to as the "Purchase." As a result of
the consummation of the Purchase, Mr. Wygod and SN Investors own an aggregate
of approximately 29.8% of the outstanding Common Stock as of January 31, 1997
and Merck no longer owns an equity interest in the Company. The shares of
Common Stock purchased by the Company are being held as treasury shares and
are no longer outstanding or entitled to vote.     
 
                                      21
<PAGE>
 
   
  As more fully described in the 1996 10-K, the Investment Agreement provides
that, until the earliest to occur of December 14, 1998, the death or
adjudication of incompetency of Mr. Wygod or a Change of Control (as defined
in the Investment Agreement) (the "Restriction Period"), (a) Mr. Wygod and SN
Investors are required to vote (or cause to be voted) the Wygod Shares (i)
with respect to election of directors, for the nominees who would have been
elected based on the vote of all shares of Common Stock, other than the Wygod
Shares, in proportion to the votes that such nominees received, and (ii) on
all other matters to come before the stockholders of the Company, in the same
manner as a majority of the outstanding shares of Common Stock (other than the
Wygod Shares) are voted and (b) except for sales pursuant to a tender or
exchange offer for the shares of Common Stock that is not opposed by the Board
of Directors of the Company, neither Mr. Wygod nor SN Investors may transfer
interests in the Wygod Shares (except that Mr. Wygod may transfer interests in
SN Investors to the extent otherwise permitted by the Investment Agreement). A
"Change of Control" under the Investment Agreement includes (A) various types
of business combinations or other extraordinary transactions, (B) certain
changes in the composition of a majority of the Board of Directors of the
Company and (C) the issuance by the Company following the closing of the
Purchase of shares of Common Stock constituting in the aggregate more than 50%
of the shares of Common Stock outstanding as of immediately following the
closing of the Purchase. As of January 31, 1997, the Company had issued
5,014,748 shares of Common Stock since the closing of the Purchase.
Accordingly, the issuance of an aggregate of 1,241,002 additional shares of
Common Stock would be a "Change of Control" as described in clause (C) above.
Upon the expiration of the obligations of Mr. Wygod and SN Investors as
described in this paragraph, Mr. Wygod and SN Investors may be in a position
to influence the election of the Company's Board of Directors as well as the
direction and future operations of the Company.

                           DESCRIPTION OF DEBENTURES
 
  The Debentures will be issued pursuant to an Indenture dated as of February
 , 1997 (the "Indenture"), a copy of which is filed as an exhibit to the
Registration Statement, between the Company and United States Trust Company of
New York, as trustee (the "Trustee").
 
  The terms of the Debentures include those stated in the Indenture and those
made part of the Indenture by reference to the Trust Indenture Act of 1939
(the "Trust Indenture Act") as in effect on the date of the Indenture. The
Debentures are subject to all such terms, and holders of the Debentures are
referred to the Indenture and the Trust Indenture Act for a statement thereof.
A copy of the Form of Indenture is filed an exhibit to the Registration
Statement of which this Prospectus is a part. The following summary of certain
provisions of the Indenture does not purport to be complete and is qualified
in its entirety by reference to the Indenture, including the definition
therein of certain terms used below. As used in the "Description of
Debentures" references to "the Company" refer to Synetic, Inc. and not to any
of its subsidiaries.
 
GENERAL
   
  The Debentures will be general unsecured obligations of the Company,
subordinate in right of payment to certain other obligations of the Company,
and convertible at any time prior to maturity, unless previously redeemed or
repurchased, into Common Stock of the Company as described below. The
Debentures will be limited to $100,000,000 aggregate principal amount
($115,000,000 aggregate principal amount if the Underwriter's over-allotment
option is exercised in full). The Debentures will bear interest from the date
of initial issuance,        , 1997, at the rate per annum shown on the cover
page of this Prospectus, payable semiannually on August 15 and February 15 in
each year to holders of record of Debentures at the close of business on the
August 1 or February 1 next preceding the interest payment date. The first
interest payment date will be August 15, 1997. Interest will be computed on
the basis of a 360-day year of twelve 30-day months. The Debentures will
mature on February 15, 2007, and will be issued in denominations of $1,000 and
integral multiples thereof and will be issued only in fully registered form.
       
  Prior to the offering of the Debentures, there has been no public trading
market for the Debentures. Although the Company intends to make application to
list the Debentures on the Nasdaq SmallCap Market, there can be no assurance
that an active public market for the Debentures will develop or, if a public
market develops, that the market price will exceed the public offering price
set forth on the covering page of this Prospectus. If an active public trading
market for the Debentures does not develop, the market prices and liquidity of
the Debentures may be adversely affected. Because the Debentures are
convertible into Common Stock, the prices at which the Debentures trade in the
market will likely be affected by the price of the Company's Common Stock.
       
  Principal and interest on the Debentures will be payable at the offices of
the Company or its agent maintained for such purposes; provided that the
payment of interest may, at the option of the Company, be made by check mailed
to a holder at his registered address. The Debentures will be convertible at
the aforesaid offices of the Company or its agent.     
 
CONVERSION OF DEBENTURES
   
  The holder of any Debenture will be entitled at any time prior to the close
of business on February 15, 2007, subject to prior redemption or repurchase,
to convert such Debenture (or portions thereof which are in denominations of
$1,000 or integral multiples thereof) at the principal amount thereof, into
shares of Common Stock, at the conversion price set forth on the cover page of
this Prospectus, subject to adjustment as described below. Interest will be
paid on any semiannual interest payment date with respect to Debentures
surrendered for conversion after the record date for the payment of interest
to the registered holder on such record date. However, Debentures surrendered
for conversion after a record date but prior to the next succeeding interest
payment date must be accompanied by payment of an amount equal to the interest
thereon which is to be paid on such interest     
 
                                      26
<PAGE>
 
   
payment date. No payment or adjustment will be made on conversion of any
Debenture for interest accrued thereon or dividends on any Common Stock
issued. The Company is not required to issue fractional shares of Common Stock
upon conversion of Debentures, and, in lieu thereof, will pay a cash
adjustment based upon the market price of the Common Stock on the last Trading
Day (as defined in the Indenture) prior to the date of conversion. In the case
of Debentures called for redemption, conversion rights will expire at the
close of business on the business day prior to the redemption date unless the
Company defaults in payment of the redemption price. A Debenture in respect of
which a holder is exercising its option to require repurchase upon the
occurrence of a Designated Event may be converted only if such holder
withdraws its election to exercise its repurchase option in accordance with
the terms of the Indenture.     
   
  The initial conversion price is subject to adjustment as set forth in the
Indenture in certain events, including: (i) the issuance of Common Stock by
the Company as a dividend or distribution on the Common Stock; (ii) certain
subdivisions, combinations, and reclassifications of the Common Stock; (iii)
the issuance of rights or warrants to all holders of Common Stock entitling
them to subscribe for or purchase shares of Common Stock (or securities
convertible into or exchangeable for shares of Common Stock) at a price per
share (or having a conversion or exercise price per share) less than the
current market price (as defined); (iv) the distribution by the Company to all
holders of Common Stock of shares of capital stock of the Company other than
Common Stock, debt securities of the Company or assets (excluding cash
dividends or distributions paid out of consolidated current or retained
earnings) or rights or warrants (other than as referred to in clause (iii)) to
purchase assets, debt securities or other securities of the Company; and (v)
the issuance, in certain circumstances, of shares of Common Stock or of
securities convertible into, or exchangeable for, shares of Common Stock
(other than pursuant to transactions described above) for a consideration per
share (or having a conversion or exchange price per share) that is less than
the then current market price of the Common Stock on the date of issuance of
such security (but excluding, among other things, issuances (a) pursuant to
any bona fide employee benefit plan of the Company now or hereafter in effect,
(b) to acquire all or any portion of a business in an arm's-length transaction
between the Company and an unaffiliated third party, (c) in a bona fide public
offering pursuant to a firm commitment underwriting or sales at the market
pursuant to a continuous offering stock program, (d) pursuant to the exercise
of warrants, rights or options, or upon the conversion of convertible
securities, which are issued and outstanding on the date hereof, or which may
be issued in the future for fair value and with an exercise price or
conversion price at least equal to the current market price of the Common
Stock at the time of issuance of such warrant, right, option or convertible
security, and (e) pursuant to a dividend reinvestment plan or other plan
hereafter adopted for the reinvestment of dividends or interest provided that
such Common Stock is issued at a price at least equal to 95% of the market
price of the Common Stock at the time of such issuance). As used above, the
"current market price" per share of Common Stock is the lower of (x) the
average of the last reported sales prices of the Common Stock (as reported by
the Nasdaq National Market) for 15 consecutive trading days commencing 25
trading days before the date in question or (y) the last reported sales price
at the most recent close of trading prior to the time in question (except
that, in the case of an issuance of rights or warrants or a distribution of
assets or securities to holders of Common Stock, clause (y) will not apply).
No adjustment in the conversion price will be required unless such adjustment
would require a change of at least 1% in the price then in effect; but any
adjustment that would otherwise be required to be made shall be carried
forward and taken into account in any subsequent adjustment. The Company may
at any time reduce the conversion price by any amount for any period of time,
provided that the conversion price is not less than the par value of a share
of Common Stock, the period during which the reduced price is in effect is at
least 20 days or such longer period as may be required by law and the reduced
price is irrevocable during such period. No adjustment to the conversion price
need be made if the holders of the Debentures participate in a transaction
which would otherwise give rise to an adjustment in the conversion price, or
will participate in such a transaction upon conversion of their Debentures, on
a basis and with notice that the Company's Board of Directors deems to be fair
and appropriate in light of the basis on which holders of the Common Stock
participate in the transaction.     
 
 
                                      27
<PAGE>
 
   
  If the Company consolidates or merges into or sells, leases, conveys or
otherwise disposes of all or substantially all of its assets to any person, as
a result of which holders of Common Stock shall be entitled to receive stock,
other securities, other property or assets (including cash) with respect to or
in exchange for such Common Stock, the Debentures would become convertible
only into the kind and amount of securities, cash or other assets which the
holders of the Debentures would have owned immediately after the transaction
if the holders had converted the Debentures immediately before the effective
date of the transaction at the conversion price in effect immediately prior to
such effective date (assuming such holders failed to exercise any rights of
election and received the kind and amount of securities, cash or other assets
received per share by a plurality of the non-electing shares).     
 
  If at any time the Company makes a distribution of property to its
stockholders which would be taxable to such stockholders as a dividend for
federal income tax purposes (e.g., distributions of evidences of indebtedness
or assets of the Company, but generally not stock dividends) and, pursuant to
the anti-dilution provisions of the Indenture, the conversion price of the
Debentures is reduced, such reduction may be deemed to be the receipt of
taxable income by the holders of Debentures.

Common Stock."     
 
OPTIONAL REDEMPTION OF DEBENTURES
 
  The Debentures will be redeemable, at the option of the Company, in whole at
any time or in part from time to time, on or after February 15, 2000, at the
redemption prices (expressed as percentages of the principal amount) set forth
below plus accrued and unpaid interest to the redemption date, if redeemed
during the 12-month period beginning February 15 of the years indicated below:

</TABLE>
 
  In the event of redemption of less than all of the Debentures, the
Debentures will be chosen for redemption by the Trustee as provided in the
Indenture, but generally pro rata or by lot. Notice of redemption will be
mailed at least 15 days but not more than 60 days before the redemption date
to each holder of Debentures to be redeemed at its registered address. On and
after the redemption date interest ceases to accrue on Debentures or portions
thereof called for redemption.
 
REPURCHASE AT OPTION OF HOLDER UPON OCCURRENCE OF A DESIGNATED EVENT
   
  If at any time there occurs any Designated Event (as defined below) with
respect to the Company, each holder of Debentures will have the right, at the
holder's option, to require the Company to repurchase all such holder's
Debentures, or a portion thereof which is $1,000 or any integral multiple
thereof, promptly following the 30th day after the date of the Company Notice
(as defined below), at 100% of their principal amount, together with accrued
and unpaid interest to the date fixed for repurchase. If a Designated Event
were to occur, there can be no assurance that the Company would have
sufficient funds to pay the repurchase price for all Debentures tendered by
the holders thereof.     
   
  Within 15 days after the occurrence of a Designated Event, the Company is
obligated to mail to holders of record of the Debentures a notice (the
"Company Notice") of the occurrence of such Designated Event and of the
repurchase right arising as a result thereof. The Company will deliver a copy
of the Company Notice to the Trustee and will cause a copy of such notice to
be published in a newspaper of general circulation in the Borough of
Manhattan, The City of New York. To exercise the repurchase right, holders of
Debentures must deliver on or before the 30th day after the date of the
Company Notice written notice to the Company (or an agent designated by the
Company for such purpose) of the holder's exercise of such right, together
with the Debentures with respect to which the right is being exercised, duly
authorized for transfer.     
 
                                      28
<PAGE>
 
   
  A Designated Event will be deemed to have occurred, subject to the
provisions below, upon the consummation of a purchase, merger, acquisition,
transfer or other transaction involving a "Change in Control". As used herein,
a "Change in Control" of the Company shall be deemed to have occurred at such
time as any person, together with such person's "affiliates" or "associates"
(as such terms are defined in Rule 12b-2 under the Exchange Act, as in effect
on the date of the Indenture), other than a Permitted Holder (collectively, an
"Acquiring Person"), first is or becomes the "beneficial owner" (as such term
is defined in Rule 13d-3 under the Exchange Act, as in effect on the date of
the Indenture), directly or indirectly, through such purchase, merger,
acquisition, transfer or other transaction, of shares of capital stock of the
Company entitling the Acquiring Person to exercise more than 50% of the total
voting power of all shares of capital stock of the Company entitled to vote in
elections of directors. A "Permitted Holder" will be defined to mean Martin J.
Wygod, his family members, any of their spouses and any Person controlled,
directly or indirectly, or beneficially owned by Martin J. Wygod or such
family members or spouses and, upon the death of Martin J. Wygod, shall also
include any executors, administrators, testamentary trustees, heirs, legatees
or beneficiaries of Martin J. Wygod and any Person controlled, directly or
indirectly, or beneficially owned by any such executors, administrators,
testamentary trustees, heirs, legatees or beneficiaries.     
   
  Notwithstanding the foregoing, a Designated Event will be deemed not to have
occurred (i) if the last sale price of the Common Stock for any five trading
days during the ten trading days immediately preceding the Change in Control
is at least equal to 105% of the conversion price in effect immediately
preceding the Change in Control or (ii) if at least 80% of the consideration
(excluding cash payments for fractional shares or cash payments for appraisal
rights) in the transaction or transactions constituting the Change in Control
consists of shares of common stock or securities convertible into common stock
that are, or upon issuance will be, traded on a national securities exchange
or through the NASDAQ National Market and the consolidated net worth of the
surviving entity (or the entity issuing common stock or securities convertible
into shares of common stock in such transaction or transactions, if such
entity guarantees the Company's obligations under the Debentures) immediately
after such transaction or transactions, as measured according to generally
accepted accounting principles as in effect on the date hereof, is equal to or
greater than the consolidated net worth of the Company immediately preceding
the Change in Control or (iii) if, in the case of an acquisition by the
Company or a subsidiary of the Company of a business for consideration
consisting of or including shares of Common Stock and/or securities
convertible into Common Stock, the terms of such acquisition provide that, (I)
from and after the consummation of such acquisition and until at least the
earlier of (x) two years from the date of such acquisition or (y) the date on
which the Acquiring Person transfers substantially all of such shares of
Common Stock and/or convertible securities, the Acquiring Person will cause
the shares of capital stock of the Company owned by it at the time of any
stockholder vote or action by consent for the election of directors of the
Company to be voted in favor of the election, as a majority of the members of
the Board of Directors of the Company, of persons who were directors or
executive officers of the Company immediately prior to entry into the
agreement or agreements pursuant to which the transaction or transactions were
consummated ("Pre-Acquisition Managers"), provided that at least a majority of
the Pre-Acquisition Managers so elected were directors or executive officers
of the Company for at least twelve months immediately prior to entry into such
agreement or agreements, and (II) the Acquiring Person will not, for a period
of two years from the consummation of the acquisition, permit persons
designated by it to become a majority of the members of the Board of Directors
of the Company. As used in the first sentence of the preceding paragraph, the
term "transfer" shall include, without limitation, a transfer of the type
referred to in clause (iii)(I)(y) of the preceding sentence but shall exclude
a transfer referred to in such clause (iii)(I)(y) as to any transferee who
agrees to be bound by the agreements of the Acquiring Person described in
clause (iii) of the preceding sentence for the remainder of the two-year
period referred to therein.     
   
  The requirement that the Company repurchase the Debentures, at the option of
the holder, upon the occurrence of a Designated Event may, in certain
circumstances, make more difficult or discourage a takeover of the Company.
This feature is not part of a plan by management to adopt a series of
antitakeover provisions but is, instead, a standard term contained in other
debenture offerings. The terms of such feature result from negotiations
between the Company and the Underwriter.

SUBORDINATION
   
  The indebtedness evidenced by the Debentures will be subordinated to the
prior payment when due of the principal of, premium, if any, and interest on
all present and future Senior Debt (as defined below). Upon maturity of any
Senior Debt, payment in full must be made on such Senior Debt before any
payment of the principal of, or interest on, the Debentures is made. During
the continuance of any default in payment of principal or premium, if any, or
interest on Senior Debt (a "Payment Default"), no payment of the principal of,
or interest on, the Debentures may be made by the Company unless and until
such default is cured or waived. Upon any distribution of assets of the
Company in any dissolution, winding-up, liquidation or reorganization of the
Company, payment of the principal of, and interest on, the Debentures will be
subordinated, to the extent and in the manner set forth in the Indenture, to
the prior payment in full of all Senior Debt. Such subordination will not
prevent the occurrence of any Event of Default (as defined in the Indenture).
By reason of such subordination, upon any distribution of assets of the
Company upon any dissolution, winding up, liquidation or reorganization, the
payment of the principal of, premium, if any and interest on the Debentures
will be subordinated to the extent provided in the Indenture in right of
payment to the prior payment in full of all Senior Debt. By reason of this
provision, in the event of the Company's dissolution or insolvency, holders of
Senior Debt may receive more, ratably, and holders of the Debentures may
receive less, ratably, than the other creditors of the Company.     
 
  "Senior Debt" means (a) the principal of, premium, if any, and interest on
all Debt (other than the Debentures), whether outstanding on the date of the
Indenture as originally executed or thereafter created or incurred, unless, in
the agreement or instrument creating or evidencing the same or pursuant to
which the same is outstanding, it is provided that such Debt is not superior
in right of payment to the Debentures, and (b) any amendment, modification,
deferral, renewal, refunding or extension of any such Senior Debt, or
debentures, notes or other evidences of indebtedness issued in exchange for
any such Senior Debt. "Debt" means (a) all indebtedness of the Company for
borrowed money, (b) all indebtedness of the Company which is evidenced by a
note, debenture, bond or other similar instrument (including capitalized lease
and purchase money obligations) and (c) all indebtedness of the Company
(including capitalized lease obligations) incurred, assumed or given in the
acquisition (whether by way of purchase, merger or otherwise) of any business,
real property or other assets, except assets acquired in the ordinary course
of the acquiror's business; any indebtedness of others described in the
preceding clauses (a), (b) and (c) which the Company has guaranteed or for
which it is otherwise liable; and any amendment, renewal, extension or
refunding of any such indebtedness. Notwithstanding the foregoing, Senior Debt
shall not include (A) indebtedness evidenced by the Debentures, (B)
indebtedness of the Company that is expressly subordinated in right of payment
to the Debentures and (C) indebtedness of the Company to an affiliate or a
subsidiary of the Company.
   
  The Debentures are obligations exclusively of the Company. Since the
operations of the Company are currently conducted through subsidiaries, the
cash flow of the Company and the consequent ability to service debt of the
Company, including the Debentures, are dependent, in part, upon the earnings
of its subsidiaries (and the distribution of those earnings to the Company or
upon loans or other payments of funds by those subsidiaries to the Company).
The subsidiaries are separate and distinct legal entities and have no
obligation, contingent or otherwise, to pay any amounts due pursuant to the
Debentures or to make any funds available therefor, whether in dividends,
loans or other payments. In addition, the payment of dividends and the making
of loans and advances to the Company by its subsidiaries may be subject to
statutory or contractual restrictions, are contingent upon the earnings of
those subsidiaries and are subject to various business considerations. The
Debentures will be effectively subordinated to all indebtedness and other
liabilities, including current liabilities and commitments under leases, if
any, of the Company's subsidiaries. Any right of the Company to receive assets
of its subsidiaries upon liquidation or reorganization of the subsidiaries
(and the consequent right of the holders of the Debentures to participate in
those assets) will be effectively subordinated to the claims of the
subsidiaries' creditors (including the subsidiaries' trade creditors), except
to the extent that the Company is itself recognized as a creditor of the
subsidiaries, in which case the claims of the Company would still be
subordinated to any security interests in the assets of such subsidiaries and
any indebtedness of such subsidiaries senior to that held by the Company. See
"Risk Factors--Holding Company Structure."     
 
                                      30
<PAGE>
 
  As of the date of this Prospectus, the Company had no Senior Debt
outstanding and the Company's subsidiaries had no indebtedness for borrowed
money. The Indenture will not restrict the incurrence of Senior Debt or other
indebtedness, secured or unsecured, by the Company or any subsidiary.
 
MERGER, CONSOLIDATION OR SALE OF ASSETS
 
  The Company may not consolidate or merge with or into, or sell, lease,
convey or otherwise dispose of all or substantially all of its assets to,
another corporation, person or entity unless (i) the Company is the surviving
person or the successor or transferee is a corporation organized under the
laws of the United States, any state thereof or the District of Columbia, or a
corporation or comparable legal entity organized under the laws of a foreign
jurisdiction and whose equity securities are listed on a national securities
exchange in the United States or authorized for quotation on the Nasdaq
National Market (provided, however, that in the case of a transaction where
the surviving entity is organized under the laws of a foreign jurisdiction,
the Company may not consummate the transaction without first making provision
for the satisfaction of its obligations to repurchase Debentures following a
Designated Event, if any), (ii) the successor assumes all the obligations of
the Company under the Debentures and the Indenture and (iii) after such
transaction no Event of Default exists.
 
COVENANTS
 
  The Company shall not adopt any plan of liquidation (other than a plan of
liquidation incident to a permitted merger, consolidation, sale of assets or
other transaction described in the preceding paragraph) which provides for,
contemplates or the effectuation of which is preceded by, (i) the sale, lease,
conveyance or other disposition of all or substantially all of the assets of
the Company otherwise than substantially as an entirety and (ii) the
distribution of all the proceeds of such sale, lease, conveyance or other
disposition unless the Company makes provisions for satisfaction of the
Company's obligation to pay principal and interest on the Debentures.
 
EVENTS OF DEFAULT AND REMEDIES
   
  An Event of Default is: default for 30 days in payment of interest on the
Debentures; default in payment when due of principal and premium, if any;
failure by the Company for 30 days after notice to comply with any of its
other agreements in the Indenture or the Debentures, or in the case of failure
by the Company to comply with the restrictions on liquidation and on
consolidation, merger or transfer or lease of substantially all of its assets
or the provisions regarding the conversion of Debentures, with such notice but
without such passage of time; default by the Company or a Significant
Subsidiary (as defined below) under and acceleration prior to maturity of, or
the failure to pay at maturity, certain other indebtedness of the Company or a
Significant Subsidiary for money borrowed aggregating in excess of $10,000,000
and continuance of such default for 30 days after notice; and certain events
of bankruptcy or insolvency. "Significant Subsidiary" means a "significant
subsidiary" as defined in Rule 1-02 of Regulation S-X under the Securities Act
and the Exchange Act (as such Regulation is in effect on the date of issuance
of the Debentures).     
 
  If any Event of Default occurs and is continuing, the Trustee or the holders
of at least 25% in principal amount of the then outstanding Debentures may
declare all the Debentures to be due and payable immediately; except that in
the case of an Event of Default arising from certain events of bankruptcy or
insolvency, all outstanding Debentures become due and payable without any
action or notice by the Trustee or any holder. Holders of the Debentures may
not enforce the Indenture or the Debentures except as provided in the
Indenture. Subject to certain limitations, holders of a majority in principal
amount of the then outstanding Debentures may direct the Trustee in its
exercise of any trust or power. The Trustee may withhold from holders of the
Debentures notice of any continuing Default or Event of Default (except a
Default or Event of Default in payment of principal or interest) if it
determines that withholding notice is in their interest.
 
  The holders of a majority in aggregate principal amount of the Debentures
then outstanding may on behalf of the holders of all of the Debentures waive
any past Default or Event of Default under the Indenture and its consequences
except a Default in the payment of interest on, or the principal of, the
Debentures or a Default or an Event of Default arising with respect to the
conversion rights of holders.
 
                                      31
<PAGE>
 
  The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and upon becoming aware of any
Default or Event of Default, a statement specifying such Default or Event of
Default.
 
  A director, officer, employee or stockholder, as such, of the Company shall
not have any liability for any obligations of the Company under the Debentures
or the Indenture or for any claim based on, in respect of, or by reason of,
such obligations or their creation. Each holder of the Debentures by accepting
a Debenture waives and releases all such liability. The waiver and release are
part of the consideration for issuance of the Debentures.
 
SATISFACTION AND DISCHARGE OF THE INDENTURE
 
  The Company may terminate its obligations under the Indenture at any time by
delivering all outstanding Debentures to the Trustee for cancellation. After
all the Debentures have been called for redemption, the Company may terminate
all of its obligations under the Indenture, other than its obligations to pay
the principal of and interest on the Debentures and certain other obligations,
at any time, by depositing with the Trustee money or non-callable U.S.
Government obligations sufficient to pay all remaining indebtedness on the
Debentures.
 
AMENDMENT, SUPPLEMENT AND WAIVER
   
  Subject to certain exceptions, the Indenture or the Debentures may be
amended or supplemented with the consent of the holders of at least a majority
in principal amount of such then outstanding Debentures, and any existing
default or compliance with any provision may be waived with the consent of the
holders of a majority in principal amount of the then outstanding Debentures.
Without the consent of any holder of the Debentures, the Company and the
Trustee may amend or supplement the Indenture or the Debentures to cure any
ambiguity, defect or inconsistency, to provide for uncertificated Debentures
in addition to or in place of certificated Debentures, to provide for the
assumption of the Company's obligations to holders of the Debentures in the
case of a merger or acquisition, or to make any change that, in the opinion of
the Company's Board of Directors, does not materially adversely affect the
legal rights of any holder of the Debentures. Without the consent of each
holder affected, the Company may not reduce the principal amount of Debentures
the holders of which must consent to an amendment of the Indenture; reduce the
rate or change the interest payment time of any Debenture; reduce the
principal of or change the fixed maturity of any Debenture or alter the
redemption provision with respect thereto; make any Debenture payable in money
other than that stated in the Debenture; make any change in the provisions
concerning waiver of Defaults or Events of Default by holders of the
Debentures or rights of holders to receive payment of principal or interest;
make any change that adversely affects the right to convert any Debenture; or
make any change in the subordination provisions that adversely affects the
rights of any holder.     
 
CONCERNING THE TRUSTEE
 
  United States Trust Company of New York will be Trustee under the Indenture.
The Trustee has certain banking relationships with the Company.
 
  The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases, or to realize on certain property received in respect of any
such claim as security or otherwise. The Trustee will be permitted to engage
in other transactions; however, if it acquires any conflicting interest (as
defined), it must eliminate such conflict or resign.
 
  The holders of a majority in principal amount of the then outstanding
Debentures will have the right to direct the time, method and place of
conducting any proceeding for exercising any remedy available to the Trustee.
The Indenture provides that in case an Event of Default shall occur (which
shall not be cured), the Trustee will be required, in the exercise of its
power, to use the degree of care of a prudent man in the conduct of his own
affairs. Subject to such provisions, the Trustee will be under no obligation
to exercise any of its rights or powers under the Indenture at the request of
any of the holders of the Debentures, unless they shall have offered to the
Trustee security and indemnity satisfactory to it.
 
REPORTS TO DEBENTUREHOLDERS
 
  The Company intends to furnish to holders of the Debentures all quarterly
and annual reports which it furnishes to holders of its Common Stock.
 
                                      32
<PAGE>
 
                         DESCRIPTION OF CAPITAL STOCK
 
  The following description of the capital stock of the Company is subject to
the Delaware General Corporation Law and to provisions contained in the
Company's Certificate of Incorporation and By-Laws, copies of which are
exhibits to the 1996 10-K that is incorporated by reference into this
Prospectus. Reference is made to such exhibits for a detailed description of
the provisions thereof summarized below.
 
  The authorized capital stock of the Company consists of 10,000,000 shares of
Preferred Stock, $.01 par value (the "Preferred Stock"), and 50,000,000 shares
of Common Stock, $.01 par value. None of the Preferred Stock is issued and
outstanding. At January 31, 1997, there were 17,526,247 shares of Common Stock
outstanding. Holders of capital stock of the Company have no preemptive or
other subscription rights.
 
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 other 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
 
  Subject to prior rights of any Preferred Stock then outstanding, the holders
of outstanding shares of Common Stock are entitled to receive dividends out of
assets legally available therefor declared and paid by the Company. The
Company does not currently anticipate paying cash dividends to holders of its
Common Stock.
 
  Upon liquidation, dissolution or winding up of the Company, the assets
legally available for distribution to stockholders are distributable ratably
among the holders of the Common Stock at the time outstanding, subject to the
rights, if any, of the holders of any Preferred Stock then outstanding. Since
the Company's Board of Directors has the authority to fix the rights and
preferences of, and to issue, the Company's authorized but unissued Preferred
Stock without approval of the holders of its Common Stock, the rights of such
holders may be materially limited or qualified by the issuance of the
Preferred Stock.
 
VOTING RIGHTS
 
  Stockholders are entitled to one vote for each share of Common Stock held of
record, except that for the election of directors, stockholders have
cumulative voting rights. Cumulative voting for directors means that, at each
election of directors, the number of shares eligible to be voted by a
stockholder is multiplied by the number of directors to be elected. A
stockholder may cast all such stockholder's votes for a single candidate, or
may allocate them among two or more candidates in any manner such stockholder
chooses. For example, if three directors are to be elected, holders of one-
third of the shares would be able, by cumulating their votes, to elect one
director, regardless of how the other shares are voted. Currently, the Company
has 11 directors. The maximum number of directors permitted under the
Company's Certificate of Incorporation is 12. The Company expects to propose
to its stockholders to expand the number of permitted directors at its next
annual meeting of stockholders.
 
  The affirmative vote of the holders of at least two-thirds of the Company's
shares entitled to vote in an election of directors is required to amend (i)
the provisions of the Company's Certificate of Incorporation relating to
cumulative voting, classification of the Company's directors into three
classes, election of only one-third of
 
                                      33
<PAGE>
 
the Board at each annual meeting of stockholders and the power to remove
directors or fill vacancies, and (ii) the By-Laws to increase the number of
directors above 12. The Company's Certificate of Incorporation also provides
that any or all directors may be removed with or without cause prior to
completion of their term only upon the vote of holders of two-thirds of the
outstanding shares of Common Stock entitled to vote generally in the election
of directors.
 
  The provisions in the Certificate of Incorporation of the Company relating
to a staggered Board of Directors, super-majority requirements and delegation
of rights to issue Preferred Stock may have the effect not only of
discouraging tender offers or other stock acquisitions but also of deterring
existing stockholders from making management changes. A staggered Board, while
promoting stability in Board membership and management, also moderates the
pace of any change in control of the Board of Directors by extending the time
required to elect a majority, effectively requiring action in at least two
annual meetings. Moreover, a staggered Board makes it more difficult for
minority stockholders, even with cumulative voting, to elect a director. For
example, to elect one director of a non-staggered 12-member Board,
stockholders with cumulative voting would need only one-twelfth of the votes
cast. To elect one member of a staggered Board with three classes and 12
members, stockholders with cumulative voting would need one-fourth of the
votes cast. The provisions with respect to removal of directors, while
intended to prevent circumvention of benefits derived from classification of
directors and to prevent a transfer of control of the Board of Directors
through the removal process, also have the effect of preventing removal of a
director for just cause by a majority of outstanding voting shares. The
ability of the Board of Directors to issue Preferred Stock, while providing
flexibility in connection with possible acquisitions and other corporate
purposes, could make it more difficult for a third party to secure a majority
of outstanding voting stock. See "Risk Factors--Certain Antitakeover Effects."
In addition, for a description of voting restrictions on shares held by SN
Investors, see "Business--Certain Corporate History" contained elsewhere in
this Prospectus and "Certain Relationships and Related Transactions" in the
1996 10-K.
 
TRANSFER AGENT AND REGISTRAR
 
  The transfer agent and registrar for the Common Stock is Registrar &
Transfer Company.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
   
  As of January 31, 1997, the Company had 17,526,247 shares of Common Stock
outstanding. The 5,061,857 Wygod Shares (as defined in "Business--Certain
Corporate History") are "restricted securities" within the meaning of Rule
144, subject to the volume restrictions of Rule 144 but for which the two-year
holding period has expired. Additionally, 45,390 shares issued in connection
with the Avicenna Acquisition and all 106,209 shares issued in connection with
the acquisition of CareAgents are subject to a two year lock-up. In the
Avicenna Acquisition, certain employees of Avicenna received options to
purchase 161,015 shares of Common Stock, 80,522 of which vested on December
24, 1996 and 80,493 of which will vest on December 24, 1998. As additional
consideration in the Avicenna Acquisition, certain selling stockholders also
received, in the aggregate, nontransferable warrants covering 250,000 shares
of Common Stock, which are exercisable after December 23, 1998.     
 
  Of the outstanding shares as of January 31, 1997, 12,312,791 shares not
owned by SN Investors are freely tradable without restrictions or further
registration under the Securities Act; provided, however, that any shares
owned by an "affiliate" of the Company (as that term is defined in the rules
and regulations under the Securities Act) may not be resold in a public
distribution except in compliance with the registration requirements of the
Securities Act or pursuant to Rule 144 thereunder. In general, Rule 144 under
the Securities Act provides that an affiliate of the Company or any holder of
restricted securities, subject to any applicable holding period, may sell
within any three-month period a number of shares that does not exceed the
greater of 1% of the then outstanding shares of the Common Stock or the
average weekly trading volume in composite trading on all exchanges during the
four calendar weeks preceding such sale. In addition, sales under Rule 144 may
be made only through unsolicited "broker's transactions" and are subject to
various other conditions.

  As more fully set forth in "Certain Relationships and Related Transactions"
in the 1996 10-K, the Wygod Shares are subject to certain contractual
restrictions on transfer. Upon expiration of such restrictions, SN Investors
may be able to sell without registration under the Securities Act the number
of such shares permitted under Rule 144, in a transaction complying with the
registration requirements of the Securities Act or in a private transaction
not subject to such requirements. The Investment Agreement (as more fully
described in "Certain Relationships and Related Transactions" in the 1996 10-
K), provides certain demand registration rights to Mr. Wygod at Mr. Wygod's
expense, which are assignable to any permitted transferee of the Wygod Shares;
provided that in no event is the Company required to file in the aggregate
more than two registration statements in connection therewith. Mr. Wygod has
not assigned such registration rights to SN Investors. While Mr. Wygod
currently intends to assign such registration rights to SN Investors in the
event the General Partner determines to sell or otherwise transfer the Wygod
Shares under circumstances in which registration would be required, Mr. Wygod
is under no obligation to do so.

                                 UNDERWRITING
 
  Subject to the terms and conditions set forth in a purchase agreement (the
"Purchase Agreement") between the Company and Merrill Lynch, Pierce, Fenner &
Smith Incorporated (the "Underwriter"), the Company has agreed to sell to the
Underwriter, and the Underwriter has agreed to purchase from the Company, the
entire principal amount of the Debentures. The Purchase Agreement provides
that the obligations of the Underwriter are subject to certain conditions
precedent set forth in the Purchase Agreement and that the Underwriter will be
obligated to purchase all of the principal amount of Debentures offered hereby
if any of such Debentures are purchased.
 
  The Underwriter has advised the Company that it proposes initially to offer
the Debentures to the public at the 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  % of the principal amount thereof. The
Underwriter may allow, and such dealers may reallow, a discount not in excess
of  % of the principal amount thereof to certain other dealers. After the
offering contemplated hereby, the offering price, concession and discount may
be changed.
 
  The Company has granted the Underwriter an option, exercisable for 30 days
after the date of this Prospectus, to purchase up to an additional $15,000,000
principal amount of Debentures to cover over-allotments, if any, at the public
offering price set forth on the cover page hereof, less the underwriting
discount.
 
  The Company has been advised by the Underwriter that the Underwriter
presently intends to make a market in the Debentures offered hereby; however,
it is not obligated to do so. Any market making may be discontinued at any
time without notice, and there can be no assurance that an active public
market for the Debentures will develop.
   
  The Company and SN Investors have agreed not to sell, contract to sell,
transfer or otherwise dispose of, directly or indirectly, any Common Stock,
any securities convertible into or exchangeable for Common Stock or any rights
to purchase or acquire Common Stock for a period of 90 days after the date of
this Prospectus without the prior written consent of the Underwriter, other
than (i) Common Stock issuable upon the exchange of the Debentures; (ii)
Common Stock issued or sold pursuant to employee benefit plans; (iii) Common
Stock issued upon exercise of currently outstanding options or warrants; or
(iv) Common Stock issued in connection with investments in, acquisitions of,
or mergers or other combinations with other companies.     
 
  The Company has agreed to indemnify the Underwriter against certain
liabilities, including certain liabilities under the Securities Act, or to
contribute to payments the Underwriter may be required to make in respect
thereof.
 
  As set forth on the cover page of this Prospectus, at the request of the
Company, the Underwriter has reserved a portion of the Debentures for sale at
the initial offering price to certain directors, officers and employees of,
and consultants to, the Company and its subsidiaries. The aggregate principal
amount of Debentures available for sale to the general public will be reduced
to the extent such persons purchase such Debentures. Any reserved Debentures
not so purchased will be offered by the Underwriter to the general public on
the same basis as the other Debentures offered by this Prospectus.

(6) ACQUISITIONS:
 
 Avicenna--
 
  On December 24, 1996, the Company acquired the outstanding equity and
indebtedness (including employee stock options) of Avicenna Systems Corp.
("Avicenna"), a privately held, development stage company located in
Cambridge, Massachusetts, for shares of the Company's common stock with a
market value of $30.5 million. As additional consideration, the Company agreed
to issue to certain sellers, nontransferable warrants covering 250,000 shares
of Synetic, Inc., exercisable after December 23, 1998 at a price of $54.50 per
share. Avicenna's business plan has been to market and build Intranets for
managed care organizations, hospitals and physician groups. 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. Avicenna's results of operations have been included in the
Company's financial statements as of December 24, 1996.
 
  A summary of the purchase price allocation is as follows (in thousands):
 
<TABLE>

                                                                        $31,475
                                                                        =======
</TABLE>
   
  The amount allocated to purchased research and development of $28.6 million
was determined based on an appraisal using known valuation techniques and was
immediately expensed, with no corresponding tax benefit, in the period of
acquisition because such research and development was in process and had no
alternative commercial use. Remaining amounts have been allocated to
intangible assets and goodwill.     
 
  The following summary, prepared on a pro forma basis, combines the results
of operations of the Company and Avicenna assuming the acquisition was
consummated at the beginning of the period presented (in thousands, except per
share amount):

  The pro forma results are not necessarily indicative of what actually would
have occurred if the acquisition had been in effect for the entire period
presented. In addition, they are not intended to be a projection of future
results. The pro forma impact of the acquisition for the six months ended
December 31, 1995 was not material.
 
 CareAgents, Inc.--
 
  On January 23, 1996, the Company acquired privately held CareAgents, Inc.
("CareAgents") to add management resources with expertise in large-scale
commercial clinical applications, medicine and information technology.
CareAgents was an early development stage company focussed on developing
Internet-based clinical commerce applications. The Company acquired CareAgents
for shares of the Company's common stock with a market value of $5.0 million.
Such acquisition will be recorded in the quarter ended March 31,1997. The
Company expects to record a non-recurring charge to expense in the quarter
ended March 31, 1997 relating to purchased research and development costs in
conjunction with its acquisition of CareAgents in January 1997. While the
exact amount of the charge is not yet determinable, the Company does not
expect this charge to exceed $3 million.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 
              RESULTS OF OPERATIONS AND FINANCIAL CONDITION     
 
QUARTER AND SIX MONTHS ENDED DECEMBER 31, 1996 COMPARED WITH QUARTER AND SIX
MONTHS ENDED DECEMBER 31, 1995.
 
 Consolidated Results of Operations:
 
  Net sales for the quarter and six months ended December 31, 1996 increased
by $1,616,000, or 15.7%, and $1,765,000, or 8.3%, respectively, over the
comparable prior year periods as a result of sales improvements across several
product lines. The increase in sales was due principally to an increase in
sales of medical OEM porous and surgical products in the Healthcare sector and
writing instrument components in the Consumer sector.
 
  Cost of sales for the quarter and six months ended December 31, 1996
increased by $528,000, or 19.1%, and $314,000, or 2.6%, respectively, over the
comparable prior year periods due to the increase in sales volume noted above.
As a percent of net sales, cost of sales for the quarter and six months ended
December 31, 1996 decreased to 53.3% and 54.0% from 56.6% and 57.0%,
respectively, in the comparable prior year periods due principally to an
improvement in labor utilization and the leverage of fixed manufacturing
costs.
 
  Selling, general and administrative expenses for the quarter and six months
ended December 31, 1996 increased by $502,000, or 15%, and $641,000, or 9.2%,
respectively, over the comparable prior year periods due primarily to an
increase in expenses associated with the increase in sales volume noted above
and an increase in corporate overhead expenses. As a percent of net sales,
selling, general and administrative expenses for the quarter and six months
ended December 31, 1996 did not vary materially from the comparable prior year
periods.
 
  Interest and other income for the quarter and six months ended December 31,
1996 increased by $345,000, or 17.3%, and $521,000, or 12.9%, respectively,
over the comparable prior year periods principally as a result of an increase
in funds available for investment generated by cash flow from operations.
 
  During the quarter ended December 31, 1996, the Company recorded a charge to
income of $28,600,000 for purchased research and development ("R&D") costs
relating to the acquisition of Avicenna.
 
  Excluding the R&D charge discussed above, for which no tax benefit is
recognized, the effective tax rate for the quarter ended December 31, 1996
remained relatively constant at 34% as compared to the prior year period. For
the six months ended December 31, 1996, the effective tax rate decreased to
34% from 36% primarily due to an increase in income in the current year
eligible for dividends received deductions.
 
 Capital Resources and Liquidity:
 
  Cash, cash equivalents and marketable securities increased by $9,073,000 to
$171,551,000 during the six months ended December 31, 1996 principally due to
the income earned from operations. Of the $171,551,000 in cash and marketable
securities, $157,238,000 is attributable to Synetic and not its subsidiaries
and $14,313,000 is attributable to Porex.
 
  The Company believes that its cash flow from operations, cash and marketable
securities and the income earned on its investments are sufficient to meet the
anticipated working capital requirements of its business.
 
  As a result of the acquisition of Avicenna and CareAgents, the Company
expects to incur significant research and development expenses and incur
additional operating losses in connection with this new area of business until
the products and services are successfully developed or marketed. There can be
no assurances that the products or services will be successfully developed or
marketed. The rate of aggregate expenditures at Avicenna and CareAgents
immediately prior to their acquisition was approximately $1,600,000 per
quarter. Research and development expenses may be materially greater in the
future than current amounts until the Company successfully develops its
products and services. The Company, however, anticipates that such research
 
                                      F-9
<PAGE>
 
and development expenses will not exceed $2,500,000 per fiscal quarter for the
third and fourth quarters of the fiscal year ending June 30, 1997 and will not
result in net losses for the current fiscal year (excluding the non-recurring
charges for purchased research and development costs relating to the
acquisition of Avicenna and CareAgents) or for either of the fiscal quarters
ending March 31, 1997 or June 30, 1997.
 
  The Company continues to pursue an acquisition program pursuant to which it
seeks to effect one or more acquisitions or other similar business
combinations with businesses it believes have significant growth potential.
Financing for such acquisitions may come from several other sources,
including, without limitation, (a) its cash, cash equivalents and marketable
securities and (b) proceeds from the incurrence of additional indebtedness or
the issuance of common stock, preferred stock, convertible debt or other
securities. The Company currently intends to use the net proceeds from the
sale of the Debentures for general corporate purposes, which may include
acquisitions. For a further description of the Company's Acquisition Program,
see "Risk Factors--Acquisition Program" and "Business--Acquisition Program".

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Section 145 of the General Corporation Law of the State of Delaware (the
"DGCL") provides, in summary, that directors and officers of Delaware
corporations such as the Registrant are entitled, under certain circumstances,
to be indemnified against all expenses and liabilities (including attorneys'
fees) incurred by them as a result of suits brought against them in their
capacity as a director or officer if they acted in good faith and in a manner
they reasonably believed to be in or not opposed to the best interests of the
Registrant and, with respect to any criminal action or proceeding, if they had
no reasonable cause to believe their conduct was unlawful; provided that no
indemnification may be made against expenses in respect of any claim, issue or
matter as to which they shall have been adjudged to be liable to the
Registrant, unless and only to the extent that the court in which such action
or suit was brought shall determine upon application that, despite the
adjudication of liability but in view of all the circumstances of the case,
they are fairly and reasonably entitled to indemnity for such expenses which
such court shall deem proper. Any such indemnification may be made by the
company only as authorized in each specific case upon a determination by the
stockholders or disinterested directors that indemnification is proper because
the indemnitee has met the applicable standard of conduct. Article Eleven of
the Registrant's Certificate of Incorporation and Section 6.5 of the
Registrant's By-Laws entitles officers, directors and controlling persons of
the Registrant to indemnification to the full extent permitted by Section 145
of the DGCL, as the same may be supplemented or amended from time to time.
 
  Article Thirteen of the Registrant's Certificate of Incorporation provides
that no director shall have any personal liability to the Registrant or its
stockholders for any monetary damages for breach of fiduciary duty as a
director, provided that such provision does not limit or eliminate the
liability of any director (i) for breach of such director's duty of loyalty to
the Registrant or its stockholders, (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) under Section 174 of the DGCL (involving certain unlawful dividends or
stock repurchase) or (iv) for any transaction from which such director derived
an improper personal benefit. Amendment to such article does not affect the
liability of any director for any act or omission occurring prior to the
effective time of such amendment.
   
  Reference is made to the Form of Indemnification Agreement between the
Registrant and its directors and officers filed as Exhibit 10.1 to this
Registration Statement pursuant to which the Registrant has agreed to
indemnify such directors and officers to the fullest extent permitted by
Delaware law, as the same may be amended from time to time.

ITEM 17. UNDERTAKINGS
 
  (a) The undersigned Registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities 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.
 
    (2) 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 that
  time shall be deemed to be the initial bona fide offering thereof.
 
  (b) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in this
Registration Statement shall be deemed to be a new Registration Statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
   
  (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the 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 expressed in the
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered hereby, 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.
