Item 6. Indemnification of Directors and Officers.

                  The Registrant's By-laws require the Registrant to indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed proceeding by reason of the fact that he is or
was a director or officer of the Registrant or is or was serving at the request
of the Registrant as a director, officer, employee, fiduciary or agent of
another corporation, trust or other enterprise against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by him in connection with such proceeding if he acted in
good faith and in a manner he reasonably believed to be in, or not opposed to,
the best interests of the Registrant, and, with respect to any such criminal
proceeding, had no reasonable cause to believe his conduct was unlawful. Such
indemnification as to expenses is mandatory to the extent the individual is
successful on the merits of the matter. Pennsylvania law permits the Registrant
to provide similar indemnification to employees and agents who are not directors
or officers. The determination of whether an individual meets the applicable
standard of conduct may be made by the disinterested directors, independent
legal counsel or the stockholders. Pennsylvania law also permits indemnification
in connection with a proceeding brought by or in the right of the Registrant to
procure a judgment in its favor. The Registrant has entered into an
Indemnification Agreement with each of its directors. Insofar as indemnification
for liabilities arising under the Securities Act of 1933, as amended (the
"Act"), may be permitted to directors, officers, or persons controlling the
Registrant pursuant to the foregoing provisions, the Registrant has been
informed that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in that Act and is
therefore unenforceable. The Registrant has obtained a directors and officers
liability insurance policy.

Item 7. Exemption from Registration Claimed.

                  In granting the options and selling the underlying securities
upon exercise which constitute the "restricted securities" which are being
registered for reoffer and resale pursuant to this Registration Statement, the
Registrant is relying on the exemptions to registration set forth in Rule 701
under, and Section 4(2) of, the Act.

Item 8. Exhibits.

                  The following is a list of exhibits filed as part of the
Registration Statement:

         5        Opinion of Saul, Ewing, Remick & Saul

                  accountants

                  declared effective by the Securities and Exchange Commission
                  on April 17, 1996).

Item 9. Undertakings.

         (a)      The undersigned Registrant hereby undertakes:

                  (1) To file, during any period in which offers or sales are
         being made, a post-effective amendment to this Registration Statement:

                           (i) To include any prospectus required by Section
                  10(a)(3) of the Securities Act of 1933;

                           (ii) To reflect in the prospectus any facts or events
                  arising after the effective date of the Registration Statement
                  (or the most recent post-effective amendment thereof) which,
                  individually or in the aggregate, represent a fundamental
                  change in the information set forth in the Registration
                  Statement;

                           (iii) To include any material information with
                  respect to the plan of distribution not previously disclosed
                  in the Registration Statement or any material change to such
                  information in the Registration Statement;

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

                  (3) To remove from registration by means of a post-effective
         amendment any of the securities being registered which remain unsold at
         the termination of the offering.

         (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 Section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in the
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

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

                                  RISK FACTORS


         Investment in the Common Stock offered hereby involves certain risks.
Before deciding to purchase any of the Common Stock offered hereby, prospective
investors should carefully consider the following factors, among others set
forth in this Prospectus.

         Dependence on Pharmaceutical Industry. The Company has in the past
derived, and may in the future derive, a significant portion of its revenues
from companies in the pharmaceutical industry. Revenues derived by the Company
from the pharmaceutical industry during 1993, 1994 and 1995 accounted for
approximately 59%, 61% and 64%, respectively, of total revenues. In particular,
the Company's revenues are highly dependent on research and development
expenditures by the pharmaceutical industry. The Company's operations could be
materially and adversely affected by certain changes in the general economic
environment within the pharmaceutical industry or the impact of the current
trend toward consolidation in or decreases in research and development
expenditures in that industry. Furthermore, the Company has benefited to date
from the increasing tendency of pharmaceutical companies to outsource large
information technology dependent research projects. A reversal or slowing of
this trend would have a material adverse effect on the Company's results of
operations.

         Attraction and Retention of Technical Employees. The Company's business
involves the delivery of professional services and is, therefore,
labor-intensive. The Company believes that its future success will depend in
large part upon its ability to attract, retain and motivate highly skilled
employees, particularly technical employees. Information services professionals
are in great demand and are likely to remain a limited resource for the
foreseeable future. Although the Company expects to continue to attract and
retain sufficient numbers of highly skilled technical employees, there can be no
assurance that the Company will be able to do so. The loss of a significant
number of the Company's technical employees could have a material adverse impact
on the Company, including its ability to secure and complete engagements.

         Concentration and Mix of Revenues. Historically, a small number of
clients have each accounted for 10% or more of the Company's revenues. In 1994,
Merck & Company, Inc. ("Merck") accounted for approximately 17% of the Company's
revenues; and, in 1995, Air Products and Chemicals, Inc. ("Air Products") and
Merck accounted for approximately 13% and 11% of revenues, respectively. One of
these clients recently issued a request for proposals to vendors seeking to
provide information technology consulting services, although this client has
advised the Company that it will not make any determination until at least
mid-1997. An unanticipated reduction of a significant amount of business from
either of these clients may have a material adverse effect on the Company's
results of operations.

         Since the implementation of a large software application is a complex,
time intensive and costly process, clients generally undertake these projects on
an irregular basis. As a result, the amount of revenues derived by the Company
from any given client likely may vary significantly from year-to-year.
Accordingly, the Company expects that clients accounting for large portions of
its revenues will change from year-to-year. The inability of the Company to
maintain its personnel utilization rates (i.e. the ratio of hours billed to
total available hours) following the completion of large engagements, either by
securing new engagements or by utilizing its technical employees for existing
engagements, could be expected to have a material adverse effect on the
Company's results of operations during such period.

         Management of Growth and Utilization of Resources. From January 1, 1992
through December 31, 1995, the size of the Company's professional staff
increased from 61 to 254 technical personnel, including an increase of 81
technical personnel during 1995. Further significant increases are anticipated
during 1996. As employee related costs are relatively fixed, variations in the
Company's revenues and operating results can occur as a result of variations in
billing margins and utilization rates of its technical employees. If the
Company's management is unable to manage growth effectively and new technical
employees are unable to achieve anticipated performance levels, the Company's
results of operations could be adversely affected.

         Reliance on Vendor Relationships. The Company has established
non-exclusive partnership arrangements with two organizations, Documentum, Inc.
("Documentum") and DLB Systems, Inc. ("DLB"), that it believes are important to
its sales, marketing and support activities. Both Documentum and DLB market
software applications to the pharmaceutical industry. The Company's history of
integrating these vendors' software products into clients' systems has led to
strong relationships with these vendors, enhancing the Company's marketing
efforts. These partnership arrangements position the Company as a potential
systems integrator should clients or prospective clients select one of these
vendors' products. These relationships have often resulted in sales leads and
the generation of client engagements. The failure by the Company to maintain
these relationships or to establish new relationships in the future could have a
material adverse effect on the Company's results of operations.

         Technological Advances. The information technology industry has
experienced and is continuing to experience rapid technological advances and
developments. The Company's success will depend in part on its ability to
develop solutions which keep pace with continuing changes in information
processing technology, evolving industry standards and changing client
preferences. There can be no assurance that the Company will be successful in
addressing these developments on a timely basis or that, if addressed, the
Company will be successful in the marketplace. The Company's delay or failure to
address these developments would have a material adverse effect on the Company's
results of operations. In addition, there can be no assurance that technologies
developed by others will not render the Company's services noncompetitive or
obsolete.

         Competition. The commercial professional services segment of the
information technology industry includes a large number of participants and is
highly competitive. The Company competes with and faces potential competition
for client assignments and experienced personnel from a number of companies that
have significantly greater financial, technical and marketing resources and have
greater name recognition. The Company also faces competition from organizations
providing staff augmentation services to, and individuals who contract directly
with, information systems departments of existing and potential clients. The
Company's client focus primarily consists of companies within the pharmaceutical
industry for which there are a number of professional services firms seeking
information technology consulting and applications development engagements. The
Company believes that the principal competitive factors in the commercial
professional services segment of the information technology industry include
responsiveness to client needs, availability of technical personnel, speed of
applications development, quality of service, price, project management
capability and technical expertise. The Company believes that its ability to
compete also depends in part on a number of competitive factors outside its
control, including the ability of its competitors to hire, retain and motivate
qualified technical personnel, the ownership by competitors of software used by
potential clients, the development of software that would reduce or eliminate
the need for the Company's services, the price at which others offer comparable
services and the extent of its competitors' responsiveness to customer needs.

         Dependence on Key Personnel. The Company believes that its continued
success depends to a significant extent upon the efforts and abilities of its
senior management. In particular, the loss of services of David S. Lipson, the
Company's Chairman, Chief Executive Officer and President, or any of the
Company's other executive officers or senior managers could have a material
adverse effect on the Company's results of operations. The Company has entered
into employment agreements with each of its executive officers.

         Dependence on Government Regulation. A substantial portion of the
Company's business depends on the comprehensive government regulation of the
drug development process. In the United States, the general trend has been in
the direction of continued or increased regulation, although the U.S. Food and
Drug Administration (the "FDA") recently announced regulatory changes intended
to streamline the approval process for pharmaceutical and biotechnology
products.

         Control by Principal Stockholders. David S. Lipson, Safeguard
Scientifics, Inc. ("Safeguard"), and a venture capital fund comprised of
Technology Leaders II L.P. and Technology Leaders II Offshore C.V. (collectively
"Technology Leaders II"), the three largest stockholders of the Company,
beneficially own in the aggregate approximately 64.3% of the outstanding Common
Stock. As a result, such stockholders collectively have the voting power to
elect the Company's entire Board of Directors and to approve all matters
requiring stockholder approval. The vote of the shares held by Technology
Leaders II is controlled by the majority vote of an executive committee
comprised of eleven voting members and one nonvoting member; the voting members
include one person designated by a wholly-owned subsidiary of Safeguard.

         Requirements for Listing Securities on the Nasdaq National Market;
Application of the Penny Stock Rules. The Common Stock is listed by the Nasdaq
National Market. If the Company is unable to maintain the standards for
continued listing, the Common Stock could be subject to delisting from the
Nasdaq National Market. Trading, if any, in the Common Stock would thereafter be
conducted on an electronic bulletin board established for securities that do not
meet the Nasdaq listing requirements or in what is commonly referred to as the
"pink sheets." As a result, an investor may find it more difficult to dispose
of, or to obtain accurate quotations as to the price of, the Company's
securities.

         In addition, if the Company's securities were delisted, they would be
subject to the so-called penny stock rules that impose additional sales practice
requirements on broker-dealers who sell such securities to persons other than
established customers and accredited investors (generally defined as an investor
with a net worth in excess of $1,000,000 or annual income exceeding $200,000, or
$300,000 together with a spouse). For transactions covered by this rule, the
broker-dealer must make a special suitability determination for the purchaser
and must have received the purchaser's written consent to the transaction prior
to sale. Consequently, delisting, if it occurred, may affect the ability of
broker-dealers to sell the Company's securities and the ability of purchasers to
sell their securities in the secondary market.

         The Commission has adopted regulations that define a "penny stock" to
be any equity security that has a market price (as defined in the regulations)
of less than $5.00 per share or an exercise price of less than $5.00 per share,
subject to certain exceptions. For any transaction involving a penny stock,
unless exempt, the rules require the delivery, prior to the transaction, of a
disclosure schedule relating to the penny stock market. The broker-dealer also
must disclose the commissions payable to both the broker-dealer and the
registered representative, current quotations for the securities and, if the
broker-dealer is the sole market-maker, the broker-dealer must disclose this
fact and the broker-dealer's presumed control over the market. Finally, monthly
statements must be sent disclosing recent price information for the penny stock
held in the account and information on the limited market in penny stocks. As a
result, if the Common Stock is determined to be "penny stock," an investor may
find it more difficult to dispose of the Company's Common Stock.

         No Prior Market; Possible Volatility of Stock Price. Prior to the
initial public offering of the Company's Common Stock pursuant to the filing of
a Registration Statement on Form S-1 which was declared effective by the
Commission on April 17,1996, there has been no public market for the Common
Stock, and there can be no assurance that an active public market will develop
or be sustained. The public markets, in general, have from time to time
experienced extreme price and volume fluctuations, which have in some cases been
unrelated to the operating performance of particular companies, and the market
for technology stocks, such as the Common Stock, can be subject to greater price
volatility than the stock market in general. In addition, factors such as
announcements of technological innovations, announcements of new products by the
Company's competitors or third parties, and market conditions in the information
technology industry may have a significant impact on the market price of the
Common Stock.

         Possible Issuances of Preferred Stock. Shares of preferred stock may be
issued by the Company in the future without stockholder approval and upon such
terms as the Board of Directors may determine. The rights of the holders of the
Common Stock will be subject to, and may be adversely affected by, the rights of
the holders of any preferred stock that may be issued in the future. The
issuance of preferred stock, while providing flexibility in connection with
possible acquisitions and other corporate purposes, could have the effect of
making it more difficult for a third party to acquire, or of discouraging a
third party from acquiring, a majority of the outstanding stock of the Company
and potentially prevent the payment of a premium to stockholders in an
acquisition transaction. The Company has no present plans to issue any shares of
preferred stock.

         No Dividends. To date, the Company has not paid any cash dividends on
its Common Stock, and does not expect to declare or pay any cash or other
dividends in the foreseeable future. Further, the Company's bank loan agreement
prohibits the Company from declaring or paying dividends or other distributions
on its Common Stock.

                                   THE COMPANY

         The Company provides consulting services that address its clients'
information processing needs through technologically advanced solutions,
including client-server architecture, graphical user interface-based
applications, local and distributed relational databases and cross-platform
applications integration. The Company delivers consulting services in two broad
areas: applications development and network management. In the applications
development area, the Company provides expertise to its clients in the full
software development life cycle or one or more discrete phases within such
process.

         Historically, the Company has provided consulting services to
businesses in a variety of industries such as pharmaceutical, biotechnology,
chemical, publishing, software development and general manufacturing. In recent
years, however, the Company has principally focused its marketing efforts on the
pharmaceutical industry in order to exploit more effectively its extensive
experience in the implementation, development and management of information
systems used in connection with the drug development process. By virtue of this
experience, the Company's technical employees have developed a strong
understanding of the drug development process and broad expertise in the
information systems and software applications required to support this
complicated and data intensive process. In addition, the Company's technical
employees have developed a broad range of technical skills and capabilities with
respect to commercially available packaged software products that address drug
development information processing requirements.

         The Company's principal executive offices are located at 575 East
Swedesford Road, Suite 200, Wayne, Pennsylvania 19087, and its telephone number
is (610) 989-7000, its World Wide Web homepage address is http://www.iscg.com

(1)      The number of shares of Common Stock beneficially owned by any Selling
         Stockholder includes shares subject to options held by the Selling
         Stockholder that are exercisable within 60 days of the date of this
         Prospectus. The number of shares of Common Stock beneficially owned by
         any Selling Stockholder who is not an "affiliate" of the Company does
         not include any shares of Common Stock which may have been acquired by
         such non-affiliate Selling Stockholder on the open market and not
         readily known by the Company.
                              
(2)      Represents shares of Common Stock that may be acquired through the
         exercise of options granted pursuant to the Plan, without regard to
         whether such options are, or when they become, exercisable and shares
         of Common Stock previously acquired pursuant to the exercise of options
         and pursuant to certain stock splits and stock dividends thereon.

(3)      Computed in each case by assuming that all options (without regard to
         when such options become exercisable) granted to the Selling
         Stockholder under the Plan have been exercised and that the Shares
         acquired in connection with such exercise were disposed of by the
         Selling Stockholder. For purposes of computing the percentage of the
         Company's Common Stock owned by the Selling Stockholder after
         completion of this offering, it is assumed that the total number of
         shares of the Company's outstanding Common Stock includes such Shares
         and outstanding warrants that may be exercised within 60 days of the
         date of this Prospectus.

                              PLAN OF DISTRIBUTION

         The Shares of Common Stock covered by this Prospectus are being
registered by the Company for the account of the Selling Stockholders. The
Company will pay all expenses of registering the Shares, but will not receive
any of the proceeds from sales by any of the Selling Stockholders. The Company
understands that none of such Shares will be offered through underwriters.

         The Shares may be sold from time to time by the Selling Stockholders
either through one or more brokers or dealers, through privately negotiated
transactions or otherwise, at market price prevailing at the time or at prices
otherwise negotiated. In connection therewith, the Selling Stockholders and
participating brokers or dealers may be deemed to be "underwriters" within the
meaning of the Act, and commissions or discounts or any profit realized on the
sale of Shares received by a Selling Stockholder or any such broker or dealer
may be deemed to be underwriting commissions or discounts within the meaning of
the Act. As of the date of this Prospectus, the Company understands that none of
the Selling Stockholders has any agreement, arrangement or understanding with
any brokers or dealers concerning the distribution of the Shares.

                       DOCUMENTS INCORPORATED BY REFERENCE

         Incorporated herein by reference and made a part hereof are: (1) the
description of the Company's Common Stock contained in the registration
statement filed by the Company to register such securities under Section 12 of
the Exchange Act, including any amendment or report filed for the purpose of
updating such description, and (2) the Company's Quarterly Report on Form 10-Q
for the quarter ended March 31, 1996, which documents are on file with the
Commission. All documents subsequently filed by the Company pursuant to Sections
13(a), 13(c), 14 or 15(d) of the Exchange Act, prior to the termination of this
offering shall be deemed to be incorporated by reference in this Prospectus and
made a part hereof from the date of filing such documents.

                                 INDEMNIFICATION

         The Company's By-laws require the Company to indemnify any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed proceeding by reason of the fact that he is or was a director or
officer of the Company or is or was serving at the request of the Company as a
director, officer, employee, fiduciary or agent of another corporation, trust or
other enterprise against expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by him in
connection with such proceeding if he acted in good faith and in a manner he
reasonably believed to be in, or not opposed to, the best interests of the
Company, and, with respect to any such criminal proceeding, had no reasonable
cause to believe his conduct was unlawful. Such indemnification as to expenses
is mandatory to the extent the individual is successful on the merits of the
matter. Pennsylvania law permits the Company to provide similar indemnification
to employees and agents who are not directors or officers. The determination of
whether an individual meets the applicable standard of conduct may be made by
the disinterested directors, independent legal counsel or the stockholders.
Pennsylvania law also permits indemnification in connection with a proceeding
brought by or in the right of the Company to procure a judgment in its favor.
The Company has entered into an Indemnification Agreement with each of its
directors. Insofar as indemnification for liabilities arising under the
Securities Act of 1933, as amended (the "Act"), may be permitted to directors,
officers, or persons controlling the Company pursuant to the foregoing
provisions, the Company has been informed that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in that Act and is therefore unenforceable. The Company has obtained a
directors and officers liability insurance policy.

                  The documents listed in clauses (a) and (b) below are
incorporated by reference in this Registration Statement, and all documents
subsequently filed by the Registrant pursuant to Sections 13(a), 13(c), 14 and
15(d) of the Securities Exchange Act of 1934, prior to the filing of a
post-effective amendment which indicates that all securities offered have been
sold or which deregisters all securities then remaining unsold, shall be deemed
to be incorporated by this reference in this Registration Statement and to be a
part hereof from the date of filing of such documents.

         (a) The Registrant's latest prospectus dated April 17, 1996 filed
pursuant to Rule 424(b) under the Securities Act of 1933, that contains audited
financial statements for the Registrant's latest fiscal year for which such

(1)      The information called for by Part I of Form S-8 is currently included
         in the description of the Registrant's Amended and Restated 1989
         Incentive Stock Option Plan (the "Plan"). Pursuant to the Note to Part
         I of Form S-8, this information is not being filed with this Form S-8.

         Pursuant to General Instruction C of Form S-8, this Registration
         Statement contains a prospectus prepared in accordance with the
         requirements of Part I of Form S-3 relating to reofferings and resales
         of the Registrant's common stock acquired pursuant to the Plan which is
         deemed to be "restricted securities" or "control securities" and shares
         issued pursuant to certain stock dividends and stock splits thereon.

                                       -3-
Item 6. Indemnification of Directors and Officers.

                  The Registrant's By-laws require the Registrant to indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed proceeding by reason of the fact that he is or
was a director or officer of the Registrant or is or was serving at the request
of the Registrant as a director, officer, employee, fiduciary or agent of
another corporation, trust or other enterprise against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by him in connection with such proceeding if he acted in
good faith and in a manner he reasonably believed to be in, or not opposed to,
the best interests of the Registrant, and, with respect to any such criminal
proceeding, had no reasonable cause to believe his conduct was unlawful. Such
indemnification as to expenses is mandatory to the extent the individual is
successful on the merits of the matter. Pennsylvania law permits the Registrant
to provide similar indemnification to employees and agents who are not directors
or officers. The determination of whether an individual meets the applicable
standard of conduct may be made by the disinterested directors, independent
legal counsel or the stockholders. Pennsylvania law also permits indemnification
in connection with a proceeding brought by or in the right of the Registrant to
procure a judgment in its favor. The Registrant has entered into an
Indemnification Agreement with each of its directors. Insofar as indemnification
for liabilities arising under the Securities Act of 1933, as amended (the
"Act"), may be permitted to directors, officers, or persons controlling the
Registrant pursuant to the foregoing provisions, the Registrant has been
informed that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in that Act and is
therefore unenforceable. The Registrant has obtained a directors and officers
liability insurance policy.

Item 7. Exemption from Registration Claimed.

                  In granting the options and selling the underlying securities
upon exercise which constitute the "restricted securities" which are being
registered for reoffer and resale pursuant to this Registration Statement, the
Registrant is relying on the exemptions to registration set forth in Rule 701
under, and Section 4(2) of, the Act.

Item 8. Exhibits.

Item 9. Undertakings.

         (a)      The undersigned Registrant hereby undertakes:

                  (1) To file, during any period in which offers or sales are
         being made, a post-effective amendment to this Registration Statement:

                           (i) To include any prospectus required by Section
                  10(a)(3) of the Securities Act of 1933;

                           (ii) To reflect in the prospectus any facts or events
                  arising after the effective date of the Registration Statement
                  (or the most recent post-effective amendment thereof) which,
                  individually or in the aggregate, represent a fundamental
                  change in the information set forth in the Registration
                  Statement;

                           (iii) To include any material information with
                  respect to the plan of distribution not previously disclosed
                  in the Registration Statement or any material change to such
                  information in the Registration Statement;

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

                  (3) To remove from registration by means of a post-effective
         amendment any of the securities being registered which remain unsold at
         the termination of the offering.

         (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 Section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in the
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

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

                                       A-2
RISK FACTORS

         Investment in the Common Stock offered hereby involves certain risks.
Before deciding to purchase any of the Common Stock offered hereby, prospective
investors should carefully consider the following factors, among others set
forth in this Prospectus.

         Dependence on Pharmaceutical Industry. The Company has in the past
derived, and may in the future derive, a significant portion of its revenues
from companies in the pharmaceutical industry. Revenues derived by the Company
from the pharmaceutical industry during 1993, 1994 and 1995 accounted for
approximately 59%, 61% and 64%, respectively, of total revenues. In particular,
the Company's revenues are highly dependent on research and development
expenditures by the pharmaceutical industry. The Company's operations could be
materially and adversely affected by certain changes in the general economic
environment within the pharmaceutical industry or the impact of the current
trend toward consolidation in or decreases in research and development
expenditures in that industry. Furthermore, the Company has benefited to date
from the increasing tendency of pharmaceutical companies to outsource large
information technology dependent research projects. A reversal or slowing of
this trend would have a material adverse effect on the Company's results of
operations.

         Attraction and Retention of Technical Employees. The Company's business
involves the delivery of professional services and is, therefore,
labor-intensive. The Company believes that its future success will depend in
large part upon its ability to attract, retain and motivate highly skilled
employees, particularly technical employees. Information services professionals
are in great demand and are likely to remain a limited resource for the
foreseeable future. Although the Company expects to continue to attract and
retain sufficient numbers of highly skilled technical employees, there can be no
assurance that the Company will be able to do so. The loss of a significant
number of the Company's technical employees could have a material adverse impact
on the Company, including its ability to secure and complete engagements.

         Concentration and Mix of Revenues. Historically, a small number of
clients have each accounted for 10% or more of the Company's revenues. In 1994,
Merck & Company, Inc. ("Merck") accounted for approximately 17% of the Company's
revenues; and, in 1995, Air Products and Chemicals, Inc. ("Air Products") and
Merck accounted for approximately 13% and 11% of revenues, respectively. One of
these clients recently issued a request for proposals to vendors seeking to
provide information technology consulting services, although this client has
advised the Company that it will not make any determination until at least
mid-1997. An unanticipated reduction of a significant amount of business from
either of these clients may have a material adverse effect on the Company's
results of operations.

         Since the implementation of a large software application is a complex,
time intensive and costly process, clients generally undertake these projects on
an irregular basis. As a result, the amount of revenues derived by the Company
from any given client likely may vary significantly from year-to-year.
Accordingly, the Company expects that clients accounting for large portions of
its revenues will change from year-to-year. The inability of the Company to
maintain its personnel utilization rates (i.e. the ratio of hours billed to
total available hours) following the completion of large engagements, either by
securing new engagements or by utilizing its technical employees for existing
engagements, could be expected to have a material adverse effect on the
Company's results of operations during such period.

                                       A-3
Management of Growth and Utilization of Resources. From January 1, 1992
through December 31, 1995, the size of the Company's professional staff
increased from 61 to 254 technical personnel, including an increase of 81
technical personnel during 1995. Further significant increases are anticipated
during 1996. As employee related costs are relatively fixed, variations in the
Company's revenues and operating results can occur as a result of variations in
billing margins and utilization rates of its technical employees. If the
Company's management is unable to manage growth effectively and new technical
employees are unable to achieve anticipated performance levels, the Company's
results of operations could be adversely affected.

         Reliance on Vendor Relationships. The Company has established
non-exclusive partnership arrangements with two organizations, Documentum, Inc.
("Documentum") and DLB Systems, Inc. ("DLB"), that it believes are important to
its sales, marketing and support activities. Both Documentum and DLB market
software applications to the pharmaceutical industry. The Company's history of
integrating these vendors' software products into clients' systems has led to
strong relationships with these vendors, enhancing the Company's marketing
efforts. These partnership arrangements position the Company as a potential
systems integrator should clients or prospective clients select one of these
vendors' products. These relationships have often resulted in sales leads and
the generation of client engagements. The failure by the Company to maintain
these relationships or to establish new relationships in the future could have a
material adverse effect on the Company's results of operations.

         Technological Advances. The information technology industry has
experienced and is continuing to experience rapid technological advances and
developments. The Company's success will depend in part on its ability to
develop solutions which keep pace with continuing changes in information
processing technology, evolving industry standards and changing client
preferences. There can be no assurance that the Company will be successful in
addressing these developments on a timely basis or that, if addressed, the
Company will be successful in the marketplace. The Company's delay or failure to
address these developments would have a material adverse effect on the Company's
results of operations. In addition, there can be no assurance that technologies
developed by others will not render the Company's services noncompetitive or
obsolete.

         Competition. The commercial professional services segment of the
information technology industry includes a large number of participants and is
highly competitive. The Company competes with and faces potential competition
for client assignments and experienced personnel from a number of companies that
have significantly greater financial, technical and marketing resources and have
greater name recognition. The Company also faces competition from organizations
providing staff augmentation services to, and individuals who contract directly
with, information systems departments of existing and potential clients. The
Company's client focus primarily consists of companies within the pharmaceutical
industry for which there are a number of professional services firms seeking
information technology consulting and applications development engagements. The
Company believes that the principal competitive factors in the commercial
professional services segment of the information technology industry include
responsiveness to client needs, availability of technical personnel, speed of
applications development, quality of service, price, project management
capability and technical expertise. The Company believes that its ability to
compete also depends in part on a number of competitive factors outside its
control, including the ability of its competitors to hire, retain and motivate
qualified technical personnel, the ownership by competitors of software used by
potential clients, the development of software that would reduce or eliminate
the need for the Company's services, the price at which others offer comparable
services and the extent of its competitors' responsiveness to customer needs.

                                       A-4
Dependence on Key Personnel. The Company believes that its continued
success depends to a significant extent upon the efforts and abilities of its
senior management. In particular, the loss of services of David S. Lipson, the
Company's Chairman, Chief Executive Officer and President, or any of the
Company's other executive officers or senior managers could have a material
adverse effect on the Company's results of operations. The Company has entered
into employment agreements with each of its executive officers.

         Dependence on Government Regulation. A substantial portion of the
Company's business depends on the comprehensive government regulation of the
drug development process. In the United States, the general trend has been in
the direction of continued or increased regulation, although the U.S. Food and
Drug Administration (the "FDA") recently announced regulatory changes intended
to streamline the approval process for pharmaceutical and biotechnology
products.

         Control by Principal Stockholders. David S. Lipson, Safeguard
Scientifics, Inc. ("Safeguard"), and a venture capital fund comprised of
Technology Leaders II L.P. and Technology Leaders II Offshore C.V. (collectively
"Technology Leaders II"), the three largest stockholders of the Company,
beneficially own in the aggregate approximately 64.3% of the outstanding Common
Stock. As a result, such stockholders collectively have the voting power to
elect the Company's entire Board of Directors and to approve all matters
requiring stockholder approval. The vote of the shares held by Technology
Leaders II is controlled by the majority vote of an executive committee
comprised of eleven voting members and one nonvoting member; the voting members
include one person designated by a wholly-owned subsidiary of Safeguard.

         Requirements for Listing Securities on the Nasdaq National Market;
Application of the Penny Stock Rules. The Common Stock is listed by the Nasdaq
National Market. If the Company is unable to maintain the standards for
continued listing, the Common Stock could be subject to delisting from the
Nasdaq National Market. Trading, if any, in the Common Stock would thereafter be
conducted on an electronic bulletin board established for securities that do not
meet the Nasdaq listing requirements or in what is commonly referred to as the
"pink sheets." As a result, an investor may find it more difficult to dispose
of, or to obtain accurate quotations as to the price of, the Company's
securities.

         In addition, if the Company's securities were delisted, they would be
subject to the so-called penny stock rules that impose additional sales practice
requirements on broker-dealers who sell such securities to persons other than
established customers and accredited investors (generally defined as an investor
with a net worth in excess of $1,000,000 or annual income exceeding $200,000, or
$300,000 together with a spouse). For transactions covered by this rule, the
broker-dealer must make a special suitability determination for the purchaser
and must have received the purchaser's written consent to the transaction prior
to sale. Consequently, delisting, if it occurred, may affect the ability of
broker-dealers to sell the Company's securities and the ability of purchasers to
sell their securities in the secondary market.

         The Commission has adopted regulations that define a "penny stock" to
be any equity security that has a market price (as defined in the regulations)
of less than $5.00 per share or an exercise price of less than $5.00 per share,
subject to certain exceptions. For any transaction involving a penny stock,
unless exempt, the rules require the delivery, prior to the transaction, of a
disclosure schedule relating to the penny stock market. The broker-dealer also
must disclose the commissions payable to both the broker-dealer and the
registered representative, current quotations for the securities and, if the
broker-dealer is the sole market-maker, the broker-dealer must disclose this
fact and the broker-dealer's presumed control over the market. Finally, monthly
statements must be sent disclosing recent price information for the penny stock
held in the account and information on the limited market in penny stocks. As a
result, if the Common Stock is determined to be "penny stock," an investor may
find it more difficult to dispose of the Company's Common Stock.

                                       A-5
No Prior Market; Possible Volatility of Stock Price. Prior to the
initial public offering of the Company's Common Stock pursuant to the filing of
a Registration Statement on Form S-1 which was declared effective by the
Commission on April 17,1996, there has been no public market for the Common
Stock, and there can be no assurance that an active public market will develop
or be sustained. The public markets, in general, have from time to time
experienced extreme price and volume fluctuations, which have in some cases been
unrelated to the operating performance of particular companies, and the market
for technology stocks, such as the Common Stock, can be subject to greater price
volatility than the stock market in general. In addition, factors such as
announcements of technological innovations, announcements of new products by the
Company's competitors or third parties, and market conditions in the information
technology industry may have a significant impact on the market price of the
Common Stock.

         Possible Issuances of Preferred Stock. Shares of preferred stock may be
issued by the Company in the future without stockholder approval and upon such
terms as the Board of Directors may determine. The rights of the holders of the
Common Stock will be subject to, and may be adversely affected by, the rights of
the holders of any preferred stock that may be issued in the future. The
issuance of preferred stock, while providing flexibility in connection with
possible acquisitions and other corporate purposes, could have the effect of
making it more difficult for a third party to acquire, or of discouraging a
third party from acquiring, a majority of the outstanding stock of the Company
and potentially prevent the payment of a premium to stockholders in an
acquisition transaction. The Company has no present plans to issue any shares of
preferred stock.

         No Dividends. To date, the Company has not paid any cash dividends on
its Common Stock, and does not expect to declare or pay any cash or other
dividends in the foreseeable future. Further, the Company's bank loan agreement
prohibits the Company from declaring or paying dividends or other distributions
on its Common Stock.

                                       A-6
THE COMPANY

         The Company provides consulting services that address its clients'
information processing needs through technologically advanced solutions,
including client-server architecture, graphical user interface-based
applications, local and distributed relational databases and cross-platform
applications integration. The Company delivers consulting services in two broad
areas: applications development and network management. In the applications
development area, the Company provides expertise to its clients in the full
software development life cycle or one or more discrete phases within such
process.

         Historically, the Company has provided consulting services to
businesses in a variety of industries such as pharmaceutical, biotechnology,
chemical, publishing, software development and general manufacturing. In recent
years, however, the Company has principally focused its marketing efforts on the
pharmaceutical industry in order to exploit more effectively its extensive
experience in the implementation, development and management of information
systems used in connection with the drug development process. By virtue of this
experience, the Company's technical employees have developed a strong
understanding of the drug development process and broad expertise in the
information systems and software applications required to support this
complicated and data intensive process. In addition, the Company's technical
employees have developed a broad range of technical skills and capabilities with
respect to commercially available packaged software products that address drug
development information processing requirements.

         The Company's principal executive offices are located at 575 East
Swedesford Road, Suite 200, Wayne, Pennsylvania 19087, and its telephone number
is (610) 989-7000, its World Wide Web homepage address is http://www.iscg.com

         Stockholder includes shares subject to options held by the Selling

         Selling Stockholder. For purposes of computing the percentage of the

         and outstanding warrants that may be exercised within 60 days of the
         date of this Prospectus.

PLAN OF DISTRIBUTION

         The Shares of Common Stock covered by this Prospectus are being
registered by the Company for the account of the Selling Stockholders. The
Company will pay all expenses of registering the Shares, but will not receive
any of the proceeds from sales by any of the Selling Stockholders. The Company
understands that none of such Shares will be offered through underwriters.

         The Shares may be sold from time to time by the Selling Stockholders
either through one or more brokers or dealers, through privately negotiated
transactions or otherwise, at market price prevailing at the time or at prices
otherwise negotiated. In connection therewith, the Selling Stockholders and
participating brokers or dealers may be deemed to be "underwriters" within the
meaning of the Act, and commissions or discounts or any profit realized on the
sale of Shares received by a Selling Stockholder or any such broker or dealer
may be deemed to be underwriting commissions or discounts within the meaning of
the Act. As of the date of this Prospectus, the Company understands that none of
the Selling Stockholders has any agreement, arrangement or understanding with
any brokers or dealers concerning the distribution of the Shares.

                       DOCUMENTS INCORPORATED BY REFERENCE

         Incorporated herein by reference and made a part hereof are: (1) the
description of the Company's Common Stock contained in the registration
statement filed by the Company to register such securities under Section 12 of
the Exchange Act, including any amendment or report filed for the purpose of
updating such description, and (2) the Company's Quarterly Report on Form 10-Q
for the quarter ended March 31, 1996, which documents are on file with the
Commission. All documents subsequently filed by the Company pursuant to Sections
13(a), 13(c), 14 or 15(d) of the Exchange Act, prior to the termination of this
offering shall be deemed to be incorporated by reference in this Prospectus and
made a part hereof from the date of filing such documents.

                                 INDEMNIFICATION

         The Company's By-laws require the Company to indemnify any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed proceeding by reason of the fact that he is or was a director or
officer of the Company or is or was serving at the request of the Company as a
director, officer, employee, fiduciary or agent of another corporation, trust or
other enterprise against expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by him in
connection with such proceeding if he acted in good faith and in a manner he
reasonably believed to be in, or not opposed to, the best interests of the
Company, and, with respect to any such criminal proceeding, had no reasonable
cause to believe his conduct was unlawful. Such indemnification as to expenses
is mandatory to the extent the individual is successful on the merits of the
matter. Pennsylvania law permits the Company to provide similar indemnification
to employees and agents who are not directors or officers. The determination of
whether an individual meets the applicable standard of conduct may be made by
the disinterested directors, independent legal counsel or the stockholders.
Pennsylvania law also permits indemnification in connection with a proceeding
brought by or in the right of the Company to procure a judgment in its favor.
The Company has entered into an Indemnification Agreement with each of its
directors. Insofar as indemnification for liabilities arising under the
Securities Act of 1933, as amended (the "Act"), may be permitted to directors,
officers, or persons controlling the Company pursuant to the foregoing
provisions, the Company has been informed that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in that Act and is therefore unenforceable. The Company has obtained a
directors and officers liability insurance policy.
