  The following summary is qualified in its entirety by reference to, and
should be read in conjunction with, the more detailed information and the
Consolidated Financial Statements and related Notes thereto appearing elsewhere
in this Prospectus. Unless otherwise indicated, all information contained in
this Prospectus assumes that the Underwriters' over-allotment option is not

                                  THE COMPANY
 
  Mastech Corporation ("Mastech" or the "Company") is a worldwide provider of
information technology ("IT") services to large and medium-sized organizations.
Mastech provides its clients with a single source for a broad range of
applications solutions and services, including client/server design and
development, conversion/migration services, Year 2000 services, Enterprise
Resource Planning ("ERP") package implementation services, Internet/intranet
services and applications maintenance outsourcing. These services are provided
in a variety of computing environments and use leading technologies, including
client/server architectures, object-oriented programming languages and tools,
distributed database management systems and the latest networking and
communications technologies. To enhance its services, Mastech has formed
business alliances with leading software companies such as Baan, Oracle and
PeopleSoft. In addition, the Company has developed its own proprietary
methodologies and tools, under the name SmartAPPS, that enhance the
productivity of the Company's Year 2000 and other services.
 
  Mastech's revenues have grown from $13.5 million in 1991 to $123.4 million in
1996 and $135.8 million for the nine months ended September 30, 1997. During
1997, Mastech has provided IT services to over 475 clients worldwide in a
diverse range of industries. These clients include AT&T, Citibank, EDS, IBM,
Intel, Oracle and Wal-Mart. The Company sets high standards for client
responsiveness and project quality. A significant number of the Company's
clients have selected Mastech on a recurring basis to provide additional
services.
 
  Mastech believes that the growth of the IT services industry offers
significant opportunities and has developed a set of strategies that the
Company believes differentiate it from competitors. These strategies include:
(i) the development of a global recruitment network through which the Company
recruits and deploys qualified IT professionals from a number of countries to
address the shortage of IT professionals in the U.S. and other developed
countries; (ii) a focus on applications services including ERP package
implementation, Year 2000 and Internet/intranet services; (iii) the development
of proprietary technology, including an automated tool for Year 2000 code
conversions and other programming language translations; (iv) international
expansion to leverage the growing need for value-added IT services in areas
outside the U.S.; and (v) the development of an extensive offshore software
development infrastructure to provide cost advantages to clients that are
increasingly short of resources.
 
  One of the key elements of Mastech's growth has been its ability to recruit
and deploy, on short notice, experienced IT professionals on a worldwide basis.
As of September 30, 1997, the Company employed approximately 2,400 IT
professionals, over 1,500 of whom were in the U.S., with the remainder in
Canada, Europe, the Middle East, Singapore, Japan, India and Australia. To
support the Company's growth and to meet the increased demand for IT
professionals, the Company has embarked on an aggressive recruiting strategy,
designed to significantly increase the number of IT professionals hired. The
Company is also establishing a network of training centers in which it trains
new recruits in value-added technologies such as PeopleSoft, Oracle
Applications, Java/HTML and Year 2000 solutions.
 
 
                                       3
<PAGE>
 
  In 1995, the Company began marketing its services in key international
markets to meet the large and growing demand for IT services overseas and to
serve its client base of large multinational corporations that need support on
a global basis. In addition to offices in the U.S., the Company maintains
international offices in Toronto, Singapore, London, Sydney, Tokyo, Amsterdam
and the Middle East. As a result of the Company's expanding international
operations, as of September 30, 1997, it had over 470 employees working with
over 90 clients outside the U.S.
 
  To provide cost advantages to clients that are increasingly short of
resources, Mastech is investing in an extensive offshore software development
infrastructure in India, including three state-of-the-art software development
centers. The center in Bangalore, India has been operational for over a year
and is conducting over 30 engagements for Mastech clients in the U.S. and
Canada. Two additional centers are under development in Pune and Madras, India.
The Company believes that this offshore infrastructure, with the ability to
accommodate 1,500 IT professionals when complete, will represent one of the
largest offshore presences in the industry.
 
                              RECENT DEVELOPMENTS
 
  In November 1997, the Company entered into a definitive agreement to purchase
for cash the assets of an Australian IT services company. The aggregate
purchase price is not expected to exceed $6 million. The Company anticipates
closing this transaction prior to December 31, 1997. While there can be no
assurance that the Company will be successful in closing this acquisition, the
Company believes that the acquisition, if consummated, will enhance its ability
to service clients' needs and expand its market presence in Australia. See
"Risk Factors--Risks Related to Possible Acquisitions."

(1) Income from operations for the year ended December 31, 1996 reflects a non-
    recurring charge of $875,000 incurred pursuant to an agreement with an
    executive to pay, as compensation for past services, an amount equal to the
    value of 54,600 shares of Common Stock at the initial public offering price
    of $15 per share. The Company has reflected this payment along with the
    applicable tax withholdings as a non-recurring charge. In the nine months
    ended September 30, 1997, income from operations reflects a non-recurring
    charge of $389,000 relating to the amortization of deferred compensation of
    this same executive.
 
(2) The Company's S-corporation status terminated on December 16, 1996 in
    connection with the Company's initial public offering of Common Stock,
    thereby subjecting the Company's income to federal and state taxes at the
    corporate level. Pro forma net income and pro forma net income per common
    share reflect federal and state income taxes (assuming a 40% effective tax
    rate) as if the Company had been taxed as a C corporation for all periods
    presented. See Note 10 of Notes to Consolidated Financial Statements for
    information concerning the computation of pro forma net income per common
    share. In connection with the Company's conversion from S-corporation
    status to C-corporation status, the Company recorded a provision for income
    taxes of $3.9 million in the fourth quarter of 1996.
 
(3) Adjusted to give effect to the sale of 1,800,000 shares of Common Stock
    offered by the Company at the public offering price of $30 1/2 per share,

    offering. See "Use of Proceeds" and "Capitalization."

                                 RISK FACTORS
 
  In addition to the other information contained in this Prospectus, investors
should consider carefully the following factors in connection with an
investment in the shares of the Common Stock offered hereby.
 
RECRUITMENT AND RETENTION OF IT PROFESSIONALS
 
  The Company's business involves the delivery of professional services and is
labor-intensive. The Company's success depends upon its ability to attract,
develop, motivate and retain highly skilled IT professionals and project
managers, who possess the technical skills and experience necessary to deliver
the Company's services. Qualified IT professionals are in great demand
worldwide and are likely to remain a limited resource for the foreseeable
future. There can be no assurance that qualified IT professionals will
continue to be available to the Company in sufficient numbers, or that the
Company will be successful in retaining current or future employees. Failure
to attract or retain qualified IT professionals in sufficient numbers could
have a material adverse effect on the Company's business, operating results
and financial condition. Historically, the Company has done most of its
recruiting outside of the countries where the client work is performed.
Accordingly, any perception among the Company's IT professionals, whether or
not well founded, that the Company's ability to assist them in obtaining
temporary work visas and permanent residency status has been diminished, could
lead to significant employee attrition. In the first eight months of 1996, the
Company experienced a higher than normal rate of employee attrition because
the Company was experiencing delays in securing the first-stage approval for
permanent residency status for its foreign employees working in the U.S. This
attrition resulted in the Company incurring increased costs for IT
professionals and a reduction in its revenue growth. See "Business--Human
Resources," "Business--Competition" and "Management's Discussion and Analysis
of Financial Condition and Results of Operations--Overview."
 
GOVERNMENT REGULATION OF IMMIGRATION
 
  The Company recruits its IT professionals on a global basis to create a
mobile workforce that it can deploy wherever required and, therefore, must
comply with the immigration laws in the countries in which it operates,
particularly the U.S. Over 90% of Mastech's IT professionals are citizens of
other countries, with most of those in the U.S. working under H-1B temporary
visas. Under current law, there is a statutory limit of 65,000 new H-1B visas
that may be issued in any government fiscal year. In the federal fiscal year
ended September 30, 1997, this limit was reached for the first time in August.
In years in which this limit is reached, the Company may be unable to obtain
enough H-1B visas to bring sufficient foreign employees to the U.S. If the
Company were unable to obtain H1-B visas for its employees in sufficient
quantities or at a sufficient rate for a significant period of time, the
Company's business, operating results and financial condition could be
materially adversely affected. Furthermore, Congress and administrative
agencies with jurisdiction over immigration matters have periodically
expressed concerns over the levels of legal and illegal immigration into the
U.S. These concerns have often resulted in proposed legislation, rules and
regulations aimed at reducing the number of employment-based visas and
permanent residency visas that may be issued. Any changes in such laws making
it more difficult to hire foreign nationals or limiting the ability of the
Company to retain foreign employees, could require the Company to incur
additional unexpected labor costs and expenses or result in the Company having
insufficient qualified personnel to perform all of the engagements that might
otherwise be available to the Company. Any such restrictions or limitations on
the Company's hiring practices could have a material adverse effect on the
Company's business, operating results and financial condition. See "Business--
Human Resources."
 
VARIABILITY OF QUARTERLY OPERATING RESULTS
 
  The Company's revenues and operating results are subject to significant
variation from quarter to quarter depending on a number of factors, including
the timing and number of client projects commenced and completed during the
quarter, the number of working days in a quarter, employee hiring, attrition
and utilization rates and the mix of time-and-materials projects versus fixed-
price projects during the quarter. The Company recognizes revenues on time-
and-materials projects as the services are performed, while revenues on fixed-
price projects are
 
                                       6
<PAGE>
 
recognized using the percentage of completion method. Although fixed-price
projects have not contributed significantly to revenues and profitability to
date, operating results may be adversely affected in the future by cost
overruns on fixed-price projects. Because a high percentage of the Company's
expenses are relatively fixed, variations in revenues may cause significant
variations in operating results. Additionally, the Company periodically incurs
cost increases due to both the hiring of new employees and strategic
investments in its infrastructure in anticipation of future opportunities for
revenue growth. No assurances can be given that quarterly results will not
fluctuate, causing a material adverse effect on the Company's business and
financial condition. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Quarterly Results."
 
INCREASING SIGNIFICANCE OF NON-U.S. OPERATIONS AND RISKS OF INTERNATIONAL
OPERATIONS
 
  The Company's international consulting and offshore software development
operations are important elements of its growth strategy. The Company opened
offices in Canada and Singapore in 1995, Japan and the U.K. in 1996, and
Australia, the Netherlands and the Middle East during the first nine months of
1997. These operations depend greatly upon business, immigration and
technology transfer laws in those countries, and upon the continued
development of technology infrastructure. There can be no assurance that the
Company's international operations will be profitable or support the Company's
growth strategy. The risks inherent in the Company's international business
activities include unexpected changes in regulatory environments, foreign
currency fluctuations, tariffs and other trade barriers, difficulties in
managing international operations and potential foreign tax consequences,
including repatriation of earnings and the burden of complying with a wide
variety of foreign laws and regulations. The failure of Mastech to manage
growth, attract and retain personnel, manage major development efforts,
profitably deliver services, or a significant interruption of the Company's
ability to transmit data via satellite, could have a material adverse impact
on the Company's ability to successfully maintain and develop its
international operations and could have a material adverse effect on the
Company's business, operating results and financial condition.
 
  Although the Company's ownership of a U.S. trademark registration covering
the service mark "Mastech" gives the Company the presumption of ownership in
the U.S. of the "Mastech" mark for the services identified in the
registration, there can be no assurance that the Company is entitled to use
the designation "Mastech" in all international operations and there is the
possibility that third parties have superior rights to the "Mastech" mark (or
similar marks) outside the U.S. See "Business--Business Strategies" and "--
Intellectual Property Rights."
 
EXPOSURE TO REGULATORY AND GENERAL ECONOMIC CONDITIONS IN INDIA
 
  A significant element of the Company's business strategy is to increase the
utilization of its offshore software development centers in India. Mastech has
utilized an offshore software development center in Bangalore for
approximately one year and is in the process of opening two more centers in
Pune and Madras, India. The Company also operates recruiting and training
centers in India. The Indian government exerts significant influence over its
economy. In the recent past, the Indian government has provided significant
tax incentives and relaxed certain regulatory restrictions in order to
encourage foreign investment in certain sectors of the economy, including the
technology industry. Certain of these benefits that directly affect the
Company include, among others, tax holidays (temporary exemptions from
taxation on operating income), liberalized import and export duties and
preferential rules on foreign investment and repatriation. To be eligible for
certain of these tax benefits, the Company must continue to meet certain
conditions. A failure to meet such conditions in the future could result in
the cancellation of the benefits. There can be no assurance that such tax
benefits will be continued in the future at their current levels. Changes in
the business or regulatory climate of India could have a material adverse
effect on the Company's business, operating results and financial condition.
 
  Although wage costs in India are significantly lower than in the U.S. and
elsewhere for comparably skilled IT professionals, wages in India are
increasing at a faster rate than in the U.S. In the past, India has
experienced
 
                                       7
<PAGE>
 
significant inflation and shortages of foreign exchange, and has been subject
to civil unrest and acts of terrorism. Changes in inflation, interest rates,
taxation or other social, political, economic or diplomatic developments
affecting India in the future could have a material adverse effect on the
Company's business, operating results and financial condition. See "Business--
Business Strategies."
 
INTENSE COMPETITION
 
  The IT services industry is highly competitive and served by numerous
national, regional and local firms, all of which are either existing or
potential competitors of the Company. Primary competitors include participants
from a variety of market segments, including "Big Six" accounting firms,
systems consulting and implementation firms, applications software firms,
service groups of computer equipment companies, general management consulting
firms, programming companies and temporary staffing firms. Many of these
competitors have substantially greater financial, technical and marketing
resources and greater name recognition than the Company. There are relatively
few barriers to entry into the Company's markets and the Company may face
additional competition from new entrants into its markets. In addition, there
is a risk that clients may elect to increase their internal IT resources to
satisfy their applications solutions needs. Further, the IT services industry
is undergoing consolidation which may result in increasing pressure on
margins. These factors may limit the Company's ability to increase prices
commensurate with increases in compensation. There can be no assurance that
the Company will compete successfully with existing or new competitors. See
"Business--Competition."
 
CONCENTRATION OF REVENUES; RISK OF TERMINATION
 
  The Company has in the past derived, and may in the future derive, a
significant portion of its revenues from a relatively limited number of
clients. The Company's five largest clients represented approximately 30% of
revenues both for the first nine months of 1997 and the year ended December
31, 1996. EDS accounted for approximately 13% and 9%, of the Company's
revenues for the first nine months of 1997 and the year ended December 31,
1996, respectively. Most of the Company's projects are terminable by the
client without penalty. An unanticipated termination of a major project could
result in the loss of substantial anticipated revenues and could require the
Company to maintain or terminate a significant number of unassigned IT
professionals, resulting in a higher number of unassigned IT professionals
and/or significant termination expenses. The loss of any significant client or
project could have a material adverse effect on the Company's business,
operating results and financial condition. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and "Business--
Clients."
 
MANAGEMENT OF GROWTH
 
  The Company's business has experienced rapid growth over the years that
could strain the Company's managerial and other resources. Revenues have grown
from $13.5 million in 1991 to $123.4 million in 1996 and $135.8 million for
the nine months ended September 30, 1997. The number of employees has grown
from 250 in 1991 to 2,696 as of September 30, 1997. The Company's continued
growth depends on adding key managers, increasing its international
operations, adding service lines and growing its offshore infrastructure. The
Company has broadened its range of services to include Year 2000 compliance,
ERP package implementation, Internet/intranet services and offshore software
development. The Company opened offices in Canada and Singapore in 1995, Japan
and the U.K. in 1996, and Dallas, Texas, Australia, the Netherlands and the
Middle East during the first nine months of 1997. In addition, the Company's
offshore software development center in Bangalore has been operational for
over a year and two additional centers in Pune and Madras, India are scheduled
to become operational during the first quarter of 1998. Effective management
of these growth initiatives will require the Company to continue to improve
its operational, financial and other management processes and systems. The
failure to manage growth effectively could have a material adverse effect on
the Company's business, operating results and financial condition. See
"Business--Business Strategies."

RAPID TECHNOLOGICAL CHANGE; DEPENDENCE ON NEW SOLUTIONS
 
  The IT services industry is characterized by rapid technological change,
evolving industry standards, changing client preferences and new product
introductions. The Company's success will depend in part on its ability to
develop IT solutions that keep pace with changes in the IT services industry.
There can be no assurance that the Company will be successful in addressing
these developments on a timely basis or that, if these developments are
addressed, the Company will be successful in the marketplace. In addition,
there can be no assurance that products or technologies developed by others
will not render the Company's services uncompetitive or obsolete. The
Company's failure to address these developments could have a material adverse
effect on the Company's business, operating results and financial condition.
See "Business--The IT Services Industry."
 
  A significant number of organizations are attempting to migrate business
applications from a mainframe environment to advanced technologies, including
client/server architectures. As a result, the Company's ability to remain
competitive will be dependent on several factors, including its ability to
help existing employees maintain or develop mainframe skills and to train and
hire employees with skills in advanced technologies. The Company's failure to
hire, train and retain employees with such skills could have a material
adverse impact on the Company's business. See "Business--Human Resources." The
Company's ability to remain competitive will also be dependent on its ability
to design and implement, in a timely and cost-effective manner, effective
transition strategies for clients moving from the mainframe environment to
client/server or other advanced architectures. The failure of the Company to
design and implement such transition strategies in a timely and cost-effective
manner could have a material adverse effect on the Company's business,
operating results and financial condition. See "Business--The IT Services
Industry."
 
DEPENDENCE ON PRINCIPALS
 
  The success of the Company is highly dependent on the efforts and abilities
of Sunil Wadhwani and Ashok Trivedi, the Company's Co-Chairman and Chief
Executive Officer and the Company's Co-Chairman and President, respectively.
Although Messrs. Wadhwani and Trivedi have entered into employment agreements
containing noncompetition, nondisclosure and nonsolicitation covenants, these
contracts do not guarantee that they will continue their employment with the
Company or that such covenants will be enforceable. The loss of the services
of either of these key executives for any reason could have a material adverse
effect on the Company's business, operating results and financial condition.
See "Management--Executive Officers and Directors."
 
RISK OF PREFERRED VENDOR CONTRACTS
 
  The Company is a party to several "preferred vendor" contracts and is
seeking additional similar contracts in order to obtain new or additional
business from large or medium-sized clients. Clients enter into these
contracts to reduce the number of vendors and obtain better pricing in return
for a potential increase in the volume of business to the preferred vendor.
While these contracts are expected to generate higher volumes, they generally
result in lower margins. Although the Company attempts to lower costs to
maintain margins, there can be no assurance that the Company will be able to
sustain margins on such contracts. In addition, the failure to be designated a
preferred vendor, or the loss of such status, may preclude the Company from
providing services to existing or potential clients, except as a
subcontractor, which could have a material adverse effect on the Company's
business, operating results and financial condition. See "Business--Clients."
 
RISKS RELATED TO POSSIBLE ACQUISITIONS
 
  The Company may expand its operations through the acquisition of additional
businesses. There can be no assurance that the Company will be able to
identify, acquire or profitably manage additional businesses or successfully
integrate any acquired businesses into the Company without substantial
expenses, delays or other
 
                                       9
<PAGE>
 
operational or financial problems. Further, acquisitions may involve a number
of special risks, including diversion of management's attention, failure to
retain key acquired personnel, unanticipated events or circumstances and legal
liabilities and amortization of acquired intangible assets, some or all of
which could have a material adverse effect on the Company's business,
operating results and financial condition. Client satisfaction or performance
problems at a single acquired firm could have a material adverse impact on the
reputation of the Company as a whole. In addition, there can be no assurance
that acquired businesses, if any, will achieve anticipated revenues and
earnings. While the Company from time to time considers acquisition
opportunities, except for the acquisitions of affiliated companies described
in this Prospectus, it has never acquired a business. The Company recently
entered into a definitive agreement to purchase for cash the assets of an
Australian IT services company. The aggregate purchase price is not expected
to exceed $6 million. The Company anticipates closing this transaction prior
to December 31, 1997. The failure of the Company to manage its acquisition
strategy successfully could have a material adverse effect on the Company's
business, operating results and financial condition. See "Prospectus Summary--
Recent Developments."
 
INTELLECTUAL PROPERTY RIGHTS
 
  The Company's success depends in part upon certain methodologies and tools
it uses in designing, developing and implementing applications systems and
other proprietary intellectual property rights. The Company is also developing
proprietary conversion tools, specifically tools tailored to address the Year
2000 problem. The Company relies upon a combination of nondisclosure and other
contractual arrangements and trade secret, copyright and trademark laws to
protect its proprietary rights and the proprietary rights of third parties
from whom the Company licenses intellectual property. The Company enters into
confidentiality agreements with its employees and limits distribution of
proprietary information. There can be no assurance that the steps taken by the
Company in this regard will be adequate to deter misappropriation of
proprietary information or that the Company will be able to detect
unauthorized use and take appropriate steps to enforce its intellectual
property rights.
 
  Although the Company believes that its services do not infringe on the
intellectual property rights of others and that it has all rights necessary to
utilize the intellectual property employed in its business, the Company is
subject to the risk of litigation alleging infringement of third-party
intellectual property rights. Any such claims could require the Company to
spend significant sums in litigation, pay damages, develop non-infringing
intellectual property or acquire licenses to the intellectual property which
is the subject of asserted infringement. See "Business--Intellectual Property
Rights."
 
LIMITED TRADING HISTORY OF COMMON STOCK; STOCK PRICE VOLATILITY
 
  The Common Stock first became publicly traded on December 17, 1996 after the
Company's initial public offering at $15 per share. Between December 17, 1996
and November 24, 1997, the closing sale price has ranged from a low of $11 1/2
per share to a high of $35 per share. The market price of the Common Stock
could continue to fluctuate substantially due to a variety of factors,
including quarterly fluctuations in results of operations, adverse
circumstances affecting the introduction or market acceptance of new products
and services offered by the Company, announcements of new products and
services by competitors, changes in the IT environment, changes in earnings
estimates by analysts, changes in accounting principles, sales of Common Stock
by existing holders, loss of key personnel and other factors. The market price
for the Common Stock may also be affected by the Company's ability to meet
analysts' expectations, and any failure to meet such expectations, even if
minor, could have a material adverse effect on the market price of the Common
Stock. In addition, the stock market is subject to extreme price and volume
fluctuations. This volatility has had a significant effect on the market
prices of securities issued by many companies for reasons unrelated to the
operating performance of these companies. In the past, following periods of
volatility in the market price of a company's securities, securities class
action litigation has often been instituted against such a company. Any such
litigation instigated against the Company could result in substantial costs
and a diversion of management's attention and resources, which could have a
material adverse effect on the Company's business, operating results and
financial condition. See "Price Range of Common Stock."

CONTROL BY EXISTING SHAREHOLDERS
 
  Upon completion of this offering, Messrs. Wadhwani and Trivedi will
beneficially own approximately 63.4% of, and have voting power over
approximately 44.3% of, the Company's Common Stock. Messrs. Wadhwani and
Trivedi will, as a practical matter, be able to elect the entire Board of
Directors and to control or veto matters requiring shareholder approval,
including certain fundamental transactions such as a merger, consolidation or
the sale of substantially all of the assets of the Company, which may require
the approval of the holders of 66 2/3% of the votes cast. Messrs. Wadhwani and
Trivedi have entered into a shareholders agreement requiring each of them to
vote their shares of Common Stock in favor of the other in the election of
directors. The approval of the Government of India/Reserve Bank of India will
be required for the Company to continue to own Mascot Systems Private Limited
("Mascot Systems") and Scott Systems Private Limited ("Scott Systems") if the
ownership of the Company by persons of Indian origin, in the aggregate, falls
below 60% of the voting power of the Company. The Company's ability to raise
additional capital by the issuance of Common Stock or voting Preferred Stock
or to sell control of the Company to a third party or to use Common Stock to
acquire other businesses may be restricted if the Company is unable to obtain
the required approval. The Company is applying for the approval of the
Government of India for the reduction of ownership by persons of Indian origin
below the 60% level. Although there can be no assurance that such approval
will be granted, the Company is not aware of any reason why its application
should not be approved. See "The Company," "Management--Executive Officers and
Directors" and "Principal and Selling Shareholders."
 
POTENTIAL DECREASE IN DEMAND FOR YEAR 2000 SERVICES
 
  The Company earned approximately 4% and 7% of its revenues from Year 2000
engagements in the year ended December 31, 1996 and the nine months ended
September 30, 1997, respectively. The Company expects that it will continue to
receive increased revenues from additional Year 2000 engagements in the near
term. However, the Company expects that Year 2000 engagements and revenues
derived from such engagements will peak prior to calendar year 2000 as
companies address their needs. Thereafter, the Company expects that revenues
derived from Year 2000 engagements will steadily decline. In the absence of
additional revenues from other sources, a decline in such engagements could
have a material adverse effect on the Company's business, operating results
and financial condition.
 
ANTI-TAKEOVER PROVISIONS
 
  Certain provisions of the Company's Articles of Incorporation, as amended
("Articles") and the Pennsylvania Business Corporation Law (the "PBCL") will
effectively make it more difficult for a third party to acquire control of the
Company by means of a tender offer or a proxy contest for the election of
directors or otherwise. The Company's Articles contain provisions which: (i)
classify the Board of Directors into three classes, with one class being
elected each year; (ii) require the approval of holders of 66 2/3% of the
votes cast on a proposal to amend the Articles, effect a merger or
consolidation of the Company, sell, lease or exchange all or substantially all
of the Company's assets or dissolve and wind-up the affairs of the Company,
unless any such proposal is unanimously approved by all of the Company's
directors; and (iii) require the approval of four of the Company's five
directors for action by the Board of Directors. These provisions may have the
effect of lengthening the time required for a person to acquire control of the
Company through a proxy contest for the election of a majority of the Board of
Directors, may discourage bids for the Common Stock at a premium over the
market price and may deter efforts to obtain control of the Company. See
"Description of Capital Stock--Certain Provisions Affecting Control of the
Company."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
  Immediately after completion of this offering, the Company will have
23,457,500 shares of Common Stock outstanding, of which the 3,000,000 shares
sold pursuant to this offering as well as the 5,520,000 shares sold in the
initial public offering will be freely tradable without restriction or further
registration under the Securities
 
                                      11
<PAGE>
 
Act of 1933, as amended (the "Securities Act"), except those shares acquired
in the public market by affiliates of the Company. In addition, 1,253,150
shares of Common Stock (327,052 of which become exercisable on or before
December 31, 1997) are issuable upon exercise of outstanding stock options,
which shares have been registered by the Company under the Securities Act and
after issuance upon exercise will be freely tradable without restriction. Of
the remaining outstanding shares of Common Stock, 14,934,600 shares are
"restricted securities" within the meaning of Rule 144 under the Securities
Act ("Rule 144") and may only be sold at prescribed times and subject to the
manner of sale, volume, notice and information restrictions of Rule 144. The
Company and Messrs. Wadhwani and Trivedi have agreed not to offer, sell,
contract to sell or otherwise dispose of, directly or indirectly, any Common
Stock beneficially owned by them, or any securities convertible into or
exchangeable or exercisable for Common Stock, except those shares registered
and sold as part of this offering until 90 days after the date of this
Prospectus, without the prior consent of Donaldson, Lufkin & Jenrette
Securities Corporation. Following the 90 day lock-up period, all of the
restricted securities will become eligible for sale, subject to Rule 144,
except for 4,487,392 shares of Common Stock held in family trusts established
by Messrs. Wadhwani and Trivedi which may not be sold prior to November 30,
1998 pursuant to the terms of a shareholders agreement with the Company. The
Company granted Messrs. Wadhwani and Trivedi certain demand and piggyback
registration rights prior to the Company's initial public offering covering an
aggregate of 16,080,000 shares of Common Stock, which rights will be
exercised, in part, as part of this offering. Sales of substantial amounts of
such shares in the public market or the availability of such shares for future
sale could adversely affect the market price of the shares of Common Stock and
the Company's ability to raise additional capital at a price favorable to the
Company. See "Shares Eligible for Future Sale," "Management--Employment
Agreements" and "Underwriting."
 
FIXED-PRICE PROJECTS
 
  The Company undertakes certain projects billed on a fixed-price basis, which
is distinguishable from the Company's principal method of billing on a time-
and-materials basis. The failure of the Company to complete such projects
within budget would expose the Company to risks associated with cost overruns,
which could have a material adverse effect on the Company's business,
operating results and financial condition. Revenues derived from fixed-price
projects represented 2.1%, 2.6%, and 3.7% of revenues for 1995, 1996 and the
nine months ended September 30, 1997, respectively. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Overview."
 
POSSIBLE ISSUANCES OF PREFERRED STOCK
 
  Shares of Preferred Stock may be issued by the Company in the future without
shareholder 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. The Company has no present
plans to issue any shares of Preferred Stock. See "Description of Capital
Stock--Preferred Stock."
 
POTENTIAL LIABILITY TO CLIENTS
 
  Many of the Company's engagements involve projects that are critical to the
operations of its clients' businesses and provide benefits that may be
difficult to quantify. Although the Company attempts to contractually
limit its liability for damages arising from errors, mistakes, omissions or
negligent acts in rendering its services, there can be no assurance that its
attempts to limit liability will be successful. The Company's failure or
inability to meet a client's expectations in the performance of its services
could result in a material adverse change to the client's operations and
therefore could give rise to claims against the Company or damage the
Company's reputation, adversely affecting its business, operating results and
financial condition.

SIGNIFICANT UNALLOCATED NET PROCEEDS
 
  None of the anticipated net proceeds of this offering have been designated
for specific uses. Therefore, the Board of Directors will have broad
discretion with respect to the use of the net proceeds of this offering. The
principal purposes of this offering are to obtain additional working capital
and to provide liquidity to the Company's shareholders. See "Use of Proceeds."
 
BENEFITS OF OFFERING TO SELLING SHAREHOLDERS
 
  The Selling Shareholders will receive substantial proceeds from this
offering and certain other benefits in connection with this offering. This
offering will provide liquidity to the Selling Shareholders for the shares of
Common Stock they presently own. After deduction of underwriting discounts and
commissions, the aggregate realized gain as a result of this offering by the
Selling Shareholders will be approximately $34.8 million. Upon completion of
this offering, the Selling Shareholders will beneficially own an aggregate of
63.4% of the outstanding Common Stock.
 
ABSENCE OF DIVIDENDS
 
  The Company does not anticipate paying any dividends on its Common Stock in
the foreseeable future. The Company's ability to pay dividends is subject to
the requirement of its revolving credit facility with PNC Bank that the
Company satisfy certain financial covenants. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources" and "Dividend Policy."
 
FORWARD-LOOKING STATEMENTS AND ASSOCIATED RISKS
 
  Included in this Prospectus are various forward-looking statements,
including, among others, the expected growth related to the Year 2000 problem,
the Company's goals and strategies, the importance and expected growth of the
IT applications solutions market, the pace of change in the IT marketplace,
the demand for IT services, the ability of the Company to capitalize on
offshore investments and infrastructure, the Company's goal to expand service
offerings and to pursue acquisitions, and the ability to leverage Year 2000
engagements into additional contracts.
 
  These statements are forward-looking and reflect the Company's current
expectations. Such statements are subject to a number of risks and
uncertainties, including, but not limited to, changes in the economic and
political environments, changes in technology and changes in the IT

                                  THE COMPANY
 
  Since its inception in July 1986, the business of the Company has been
conducted through Mastech Systems Corporation, a Pennsylvania corporation
("Mastech Systems"). Mastech Systems is an indirect, wholly owned subsidiary
of the Company. Mastech Holding Corporation, a Delaware holding company and
wholly owned subsidiary of the Company, owns all of the issued and outstanding
stock of Mastech Systems.
 
  In addition to Mastech Systems, the Company has two wholly owned operating
subsidiaries: Mascot Systems and Scott Systems, both of which are corporations
organized under the laws of India. Mascot Systems provides offshore software
development services to the Company and its clients from India and Scott
Systems provides recruiting and training services to the Company in India.
 
  The offshore software development services provided by the Company to its
clients are provided through Mascot Systems. Mascot Systems leases from
Messrs. Wadhwani and Trivedi the real estate in Bangalore at which offshore
software development activities are conducted and expects to lease real estate
from them for the Company's planned offshore software development centers in
Pune and Madras, India. See "Business--Services" and "Certain Transactions."
 
  The Company maintains its principal executive offices at 1004 McKee Road,
Oakdale, PA 15071. The Company's World Wide Web address is www.mastech.com.
The Company's Web site is not part of this Prospectus. The Company's telephone
number is (412) 787-2100.
 
                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the 1,800,000 shares of
Common Stock offered by the Company (after deduction of underwriting discounts
and commissions and estimated offering expenses payable by the Company) will
be approximately $51.3 million based upon the public offering price of $30 1/2
per share. The Company expects to use the net proceeds from this offering for:
(i) expansion of existing operations, including the Company's international
marketing and offshore software development operations, development of new
service lines and possible acquisitions of related businesses; and (ii)
general corporate purposes, including working capital. Pending such uses, the
net proceeds of this offering will be invested in short-term, investment
grade, interest-bearing securities. The principal purposes of this offering
are to obtain additional working capital and provide liquidity to the
Company's shareholders. See "Business--Business Strategies."
 
  The Company will not receive any proceeds from the sale of Common Stock by
the Selling Shareholders. See "Principal and Selling Shareholders."

                                DIVIDEND POLICY
 
  The Company intends to retain all of its future earnings to fund growth and
the operation of its business and therefore does not anticipate paying any
cash dividends in the foreseeable future. Future cash dividends, if any, will
be at the discretion of the Company's Board of Directors and will depend upon,
among other things, the Company's future operations and earnings, capital
requirements and surplus, general financial condition, contractual
restrictions and such other factors as the Board of Directors may deem
relevant. The Company's ability to pay dividends is subject to the requirement

(1) Income from operations for the year ended December 31, 1996 reflects a
    non-recurring charge of $875,000 incurred pursuant to an agreement with an
    executive to pay, as compensation for past services, an amount equal to
    the value of 54,600 shares of Common Stock at the initial public offering
    price of $15 per share. The Company has reflected this payment along with
    the applicable tax withholdings as a non-recurring charge. In the nine
    months ended September 30, 1997, income from operations reflects a non-
    recurring charge of $389,000 relating to the amortization of deferred
    compensation of this same executive.
 
(2) The Company's S-corporation status terminated on December 16, 1996 in
    connection with the Company's initial public offering of Common Stock,
    thereby subjecting the Company's income to federal and state taxes at the
    corporate level. Pro forma net income and pro forma net income per share
    reflect federal and state taxes (assuming a 40% effective tax rate) as if
    the Company had been taxed as a C corporation for all periods presented.
    See Note 10 of Notes to Consolidated Financial Statements for information
    concerning the computation of pro forma net income per common share. In
    connection with the Company's conversion from S-corporation status to C-
    corporation status, the Company recorded a provision for income taxes of
    $3.9 million in the fourth quarter of 1996.

               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following Management's Discussion and Analysis of Financial Condition
and Results of Operations contains certain forward-looking statements that
involve substantial risks and uncertainties. When used in this section, the
words "anticipate," "believe," "estimate," "expect" and similar expressions as
they relate to the Company or its management are intended to identify such
forward-looking statements. The Company's actual results, performance or
achievements could differ materially from the results expressed in, or implied
by, these forward-looking statements. Factors that could cause or contribute
to such differences include those discussed in "Risk Factors."
 
OVERVIEW
 
  Mastech Corporation was incorporated in Pennsylvania on November 12, 1996.
Mastech Systems, a Pennsylvania corporation through which the business of the
Company has been conducted since its inception in July 1986, is an indirect,
wholly owned subsidiary of the Company. In December 1996, Mastech completed
the initial public offering of its Common Stock. Subsequent to the initial
public offering, Mascot Systems and Scott Systems, both of which are
corporations organized under the laws of India, became wholly owned
subsidiaries of Mastech Systems.
 
  Mastech is a worldwide provider of IT services to large and medium-sized
organizations. Mastech provides its clients with a single source for a broad
range of applications solutions and services, including client/server design
and development, conversion/migration services, Year 2000 services, ERP
package implementation services, Internet/intranet services and applications
maintenance outsourcing. These services are provided in a variety of computing
environments and use leading technologies, including client/server
architectures, object-oriented programming languages and tools, distributed
database management systems and the latest networking and communications
technologies.
 
  The Company's revenues are derived from fees paid by clients for
professional services. Historically, a substantial majority of the Company's
projects have been client-managed. On client-managed projects, Mastech
provides professional services as a member of the project team on a time-and-
materials basis. The Company recognizes revenues on time-and-materials
projects as the services are performed. On Mastech-managed projects, Mastech
assumes responsibility for project management and bills the client on a time-
and-materials or fixed-price basis. Fixed-price contracts are recognized by
the percentage of completion method. Revenues from international operations do
not include revenues generated through offshore software development centers
on U.S. client engagements.
 
  Mastech's most significant cost is its personnel expense, which consists
primarily of salaries and benefits of the Company's billable personnel. The
number of IT professionals assigned to projects may vary depending on the size
and duration of each engagement. Moreover, project terminations and completion
and scheduling delays may result in periods when personnel are not assigned to
active projects. Mastech manages its personnel costs by closely monitoring
client needs and basing personnel increases on specific project engagements.
 
  While the number of IT professionals may be adjusted to reflect active
projects, the Company must maintain a sufficient number of professionals to
respond to demand for the Company's services on both existing projects and new
engagements. In the first eight months of 1996, the Company experienced a
higher than normal rate of employee attrition because the Company was
experiencing delays in securing the first stage approval for permanent
residency status for some of its professionals. This attrition resulted in
increased costs for IT professionals and reduced revenue growth during this
period. In response to this attrition problem, the Company increased its U.S.
recruiting efforts, enhanced its training programs and worked with the
Department of Labor to revise its filing procedures to resolve the delays. As
a result of these initiatives, the Company's employee attrition rate returned
to normal historical levels in September 1996 and have remained at such levels
since that date.
 
                                      17
<PAGE>
 
  Since July 1995, the Company has incurred significant incremental expenses
to help ensure that the Company has both an adequate number of skilled IT
professionals and the infrastructure necessary to sustain the Company's
growth. These expenditures were incurred in connection with: (i) the
development of additional service offerings, including Year 2000 conversion
services and ERP package implementation services; (ii) the establishment of a
recruiting division to recruit IT professionals in the U.S. and worldwide;
(iii) the opening of foreign sales offices to provide better access to the
global market; (iv) the development of three offshore software development
centers in India; (v) the hiring of additional managers to support a larger
organization; (vi) the relocation of the Company's headquarters to larger,
more efficient office space; and (vii) the establishment of a training center
to improve the skill levels of new and current employees. While these expenses
have increased the Company's selling, general and administrative expenses, the
Company believes that the revenues expected to be derived as a result of these
expenditures have not yet been fully realized.

(1) Includes non-recurring charges of .7% and .3% of total revenues for the
    year ended December 31, 1996 and the nine months ended September 30, 1997,
    respectively.
 
NINE MONTHS ENDED SEPTEMBER 30, 1997 COMPARED TO NINE MONTHS ENDED SEPTEMBER
30, 1996
 
  Revenues. The Company's revenues increased 50.4%, or $45.5 million from
$90.3 million in the first nine months of 1996 to $135.8 million in the first
nine months of 1997. This growth in revenues was due primarily to successful
market penetration by the Company's domestic Enterprise Package Solutions
Division, which increased its revenues $17.2 million. The Company also
experienced an increase of $9.2 million in revenues from its preferred vendor
service contract with EDS. Additionally, the Company's international revenues
increased by $9.5 million during this same period as a result of its expansion
into the Canadian, European and Asia Pacific markets. The Company broadened
its client base from 345 clients in the first nine months of 1996 to 475
clients in the first nine months of 1997.
 
  Gross Profit. Gross profit consists of revenues less cost of revenues. Cost
of revenues consists primarily of salaries and employee benefits for billable
IT professionals and the associated travel and relocation costs of these
professionals, as well as the cost of the independent contractors used by the
Company. Gross profit increased 65.9% from $24.8 million in the first nine
months of 1996 to $41.1 million in the first nine months of 1997. Gross profit
as a percentage of revenues increased from 27.4% in the first nine months of
1996 to 30.3% in the first nine months of 1997. The primary reasons for the
$16.3 million increase were higher margins in the Company's new service areas
such as the Enterprise Package Solutions Division and a significant decline in
the number of independent contractors used by the Company. Costs associated
with the use of independent contractors as a percentage of revenues decreased
from 12.1% in the first nine months of 1996 to 5.6% in the first nine months
of 1997. The number of IT professionals (including independent contractors)
used by the Company increased from 1,394 as of September 30, 1996 to 2,471 as
of September 30, 1997.
 
                                      18

  Selling, General and Administrative Expenses. Selling, general and
administrative expenses consist of costs associated with the Company's sales
and marketing efforts, executive management, finance and human resource
functions, facilities and telecommunication costs and other general overhead
expenses. Selling, general and administrative expenses increased 70.5%, or
$10.3 million from $14.7 million for the first nine months of 1996 to $25.0
million for the first nine months of 1997. As a percentage of revenues,
selling, general and administrative expenses increased from 16.2% for the
first nine months of 1996 to 18.4% for the first nine months of 1997. The
increase in selling, general and administrative expenses reflects the
Company's continued investment in infrastructure and in the initiatives
required to implement the Company's marketing strategies. These costs include
the development of additional service offerings, the expansion of its global
recruiting capabilities, the opening of additional international offices, the
establishment of training centers and the continued expansion of its offshore
software development centers. In addition, the Company has incurred
incremental costs subsequent to the Company's initial public offering. The
incremental costs associated with the Company's public company status were
approximately $1.2 million for the first nine months of 1997.
 
  Interest and Other Income (Expense), Net. Other income was $1.0 million for
the first nine months of 1997 compared to other expense of $21,000 for the
first nine months of 1996. This increase in other income is the result of
increased interest income from the investment of the net proceeds from the
Company's initial public offering. This increase in interest income was,
however, partially offset by an increase in interest expense charged on
borrowings outstanding under the Company's revolving credit facilities,
principally to support the Company's Indian operations. These borrowings
increased the Company's interest expense from $103,000 for the first nine
months of 1996 to $426,000 for the first nine months of 1997. See "--Liquidity
and Capital Resources." Other income and expense was not significant in any
period prior to the nine months ended September 30, 1997.
 
1996 COMPARED TO 1995
 
  Revenues. The Company's revenues increased 19.0% from $103.7 million in 1995
to $123.4 million in 1996. This growth in revenues was primarily attributable
to additional services provided to existing clients, engagements with new
clients and the Company's continued expansion into international markets. The
Company broadened its client base from 308 clients in 1995 to 369 clients in
1996. Revenues from the Company's international operations increased from $1.4
million in 1995 to $11.1 million in 1996. The Company's revenue growth was
limited by higher than normal employee attrition in the first eight months of
1996.
 
  Gross Profit. Gross profit increased 8.6% from $31.3 million in 1995 to
$33.9 million in 1996. Gross profit as a percentage of revenues declined from
30.1% in 1995 to 27.5% in 1996. This decrease is directly attributable to an
increase in costs for IT professionals, including higher salaries, employee
bonuses, relocation expense and an increase in the use of independent
contractors, incurred during 1996 as a result of a higher than normal rate of
employee attrition. In the first eight months of 1996, the Company experienced
this higher than normal rate of employee attrition because the Company was
experiencing delays in securing the first-stage approval from the Department
of Labor ("DOL") for permanent residency status for some of its professionals.
This attrition resulted in increased costs for IT professionals and reduced
revenue growth. In response to this attrition problem, the Company increased
its U.S. recruiting efforts, enhanced its training programs and worked with
the DOL to revise its filing procedures to resolve the delays. As a result of
these initiatives, the Company's employee attrition rate returned to normal
historical levels in September 1996. Costs associated with the use of
independent contractors as a percentage of cost of revenues increased from
10.1% in 1995 to 16.3% in 1996. The number of IT professionals utilized by the
Company (including independent contractors) increased from 1,248 as of
December 31, 1995 to 1,529 as of December 31, 1996.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased 62.1% from $13.0 million in 1995 to $21.1
million in 1996. As a percentage of revenues, selling, general and
administrative expenses increased from 12.5% in 1995 to 17.1% in 1996. This
increase was primarily attributable to the expenses incurred to build the
infrastructure necessary to support the Company's continued revenue
 
                                      19

growth. In addition to the incremental costs previously mentioned, the Company
initiated a sales force recruiting program which resulted in a 50% increase
from 1995 to 1996 in the number of sales-related personnel. In the fourth
quarter of 1996, the Company recorded a non-recurring charge of $0.9 million
related to an executive compensation agreement which provides for, among other
things, a cash payment equal to the value of 54,600 shares of Common Stock at
the initial public offering.
 
1995 COMPARED TO 1994
 
  Revenues. The Company's revenues increased 48.0% from $70.1 million in 1994
to $103.7 million in 1995. The growth in revenues was attributable to
increased revenues from systems integrators, additional services delivered to
existing clients, engagements with new clients and, for the first time,
revenues from international operations. The Company broadened its client base
from 285 clients in 1994 to 308 clients in 1995. The increase in revenues was
partially offset by a planned decrease in government contracts.
 
  Gross Profit. Gross profit increased 55.3% from $20.1 million in 1994 to
$31.3 million in 1995. Gross profit also increased as a percentage of revenues
from 28.7% to 30.1%. This increase in margins was attributable to billing
rates increasing at a slightly higher level than professional salaries. Also,
the shift of available resources away from government contracts to more
profitable projects enabled the Company to attain a higher gross profit margin
in 1995. The increase in gross profit was partially offset by higher personnel
expenses resulting from the hiring of additional professionals to support the
increase in client engagements. The number of IT professionals increased from
1,005 as of December 31, 1994 to 1,248 as of December 31, 1995. Costs
associated with the use of independent contractors as a percentage of cost of
revenues increased from approximately 1.0% in 1994 to 10.1% in 1995.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased 48.0% from $8.8 million in 1994 to $13.0
million in 1995, representing 12.5% of revenues in both 1994 and 1995.
Expenses incurred in 1995 include costs related to the start-up of two foreign
offices, the relocation of the Company's headquarters and a general expansion
of the sales, marketing and administrative functions to support the Company's
continued revenue growth.

(1) Includes non-recurring charges of $875,000, $130,000, $129,000 and
    $130,000 in the four quarters ended September 30, 1997, respectively.
 
  The Company's revenues and operating results are subject to significant
variation from quarter to quarter depending on a number of factors, including
the timing and number of client projects commenced and completed during the
quarter, the number of working days in a quarter, employee hiring, attrition
and utilization rates and the mix of time-and-materials projects versus fixed-
price projects during the quarter. Although fixed-price projects have not
contributed significantly to revenues and profitability to date, operating
results may be adversely affected in the future by cost overruns on fixed-
price projects. Because a high percentage of the Company's expenses are
relatively fixed, variations in revenues may cause significant variations in
operating results. Additionally, the Company periodically incurs cost
increases due to both the hiring of new employees and strategic investments in
its infrastructure in anticipation of future opportunities for revenue growth.
No assurances can be given that quarterly results will not fluctuate, causing
a material adverse effect on the Company's business and financial condition.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  The net proceeds generated from the Company's initial public offering were
approximately $45.6 million, after deducting underwriting discounts and
commissions and offering expenses paid by the Company. These proceeds have
been temporarily invested in short-term, investment grade, interest bearing
securities. During the nine months ended September 30, 1997, the Company used
the net proceeds to pay approximately $0.9 million of corporate income taxes
related to the termination of its status as an S corporation. In April 1997,
the Company also paid a dividend of approximately $6.3 million of
undistributed S-corporation earnings from these proceeds.
 
                                      21
<PAGE>
 
  Prior to the initial public offering, the Company generally financed its
working capital requirements through internally generated funds. Since the
initial public offering, the Company has financed its working capital
requirements through internally generated funds and with the proceeds from the
offering. The Company's financial statements reflect cash flow used by
operations of approximately $4.3 million for the nine months ended September
30, 1997, and cash flow provided by operations of $10.1 million for the nine
months ended September 30, 1996. The Company's cash provided by operations
prior to the initial public offering does not reflect any income tax expense
due to the Company's prior status as an S corporation. Prior to the initial
public offering, the Company made S-corporation distributions to its
shareholders and in 1997 made the final S-corporation distributions.
 
  Capital expenditures for the first nine months of 1997 and 1996 were
approximately $4.0 and $1.8 million, respectively. During the first nine
months of 1997, the Company spent approximately $1.1 million in connection
with the buildout and other development of the infrastructure for its offshore
software development and training facilities in India. The Company also spent
approximately $1.2 million related to the implementation of a new management
information system during this period. The estimated remaining cost to license
and implement this new software, which is year 2000 compliant, is
approximately $800,000.
 
  Effective May 30, 1997, the Company entered into a $25.0 million revolving
credit facility (the "Facility") with PNC Bank, National Association. The
Facility bears interest at a rate equal to LIBOR plus 1.0% or prime at the
Company's option and borrowings are unsecured. The Facility contains certain
restrictive covenants and financial ratio requirements which would limit
distributions to shareholders and additional borrowings. Historically, the
Company has not used its revolving credit facilities to finance its working
capital needs, and as of September 30, 1997, $25.0 million remained available
for borrowing under the Facility.
 
  As of September 30, 1997, Mascot Systems had aggregate borrowings of
approximately $2.2 million outstanding under revolving credit agreements with
ICICI Banking Corporation Limited and IndusInd Bank Limited, both of India.
Interest rates charged on these borrowings range from 18.75% to 19.25% per
year. As of September 30, 1997, there are no additional amounts available for
borrowing under these facilities. These borrowings will be repaid by the
Company prior to December 31, 1997.
 
  The Company currently anticipates that the proceeds from this offering
together with existing sources of liquidity and cash generated from operations
will be sufficient to satisfy its cash needs at least through the next twelve
months.
 
  The Company does not believe that inflation had a significant impact on the
Company's results of operations for the periods presented. On an ongoing
basis, the Company attempts to minimize any effects of inflation on its
operating results by controlling operating costs and, whenever possible,
seeking to insure that billing rates reflect increases in costs due to
inflation.
 
  The Company invoices its clients in the local currency of the country in
which the client is located. Gains and losses as a result of fluctuations in
foreign currency exchange rates have not had a significant impact on results
of operations.
 
RECENTLY ISSUED FINANCIAL ACCOUNTING STANDARDS
 
  In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128, "Earnings per Share" (SFAS No.
128), which establishes new standards for computing and presenting earnings
per share and applies to entities with publicly and non-publicly held common
stock. SFAS No. 128 is effective for financial statements issued for periods
ending after December 15, 1997, including interim periods. Earlier application
is not permitted. SFAS No. 128 requires restatement of all prior period
earnings per share data presented. The Company has determined that the
adoption of SFAS No. 128 will not change reported earnings per share for any
periods.

SUMMARY
 
  Mastech is a worldwide provider of IT services to large and medium-sized
organizations. Mastech provides its clients with a single source for a broad
range of applications solutions and services, including client/server design
and development, conversion/migration services, Year 2000 services, ERP
package implementation services, Internet/intranet services and applications
maintenance outsourcing. These services are provided in a variety of computing
environments and use leading technologies, including client/server
architectures, object-oriented programming languages and tools, distributed
database management systems and the latest networking and communications
technologies. To enhance its services, Mastech has formed business alliances
with leading software companies such as Baan, Oracle and PeopleSoft. In
addition, the Company has developed its own proprietary methodologies and
tools, under the name SmartAPPS, that enhance the productivity of the
Company's Year 2000 and other services.
 
  Mastech's revenues have grown from $13.5 million in 1991 to $123.4 million
in 1996 and $135.8 million for the nine months ended September 30, 1997.
During 1997, Mastech has provided IT services to over 475 clients worldwide in
a diverse range of industries. These clients include AT&T, Citibank, EDS, IBM,
Intel, Oracle and Wal-Mart. The Company sets high standards for client
responsiveness and project quality. A significant number of the Company's
clients have selected Mastech on a recurring basis to provide additional
services.
 
  Mastech believes that the growth of the IT services industry offers
significant opportunities and has developed a set of strategies that the
Company believes differentiate it from competitors. These strategies include:
(i) the development of a global recruitment network through which the Company
recruits and deploys qualified IT professionals from a number of countries to
address the shortage of IT professionals in the U.S. and other developed
countries; (ii) a focus on applications services including ERP package
implementation, Year 2000 and Internet/intranet services; (iii) the
development of proprietary technology, including an automated tool for Year
2000 code conversions and other programming language translations; (iv)
international expansion to leverage the growing need for value-added IT
services in areas outside the U.S.; and (v) the development of an extensive
offshore software development infrastructure to provide cost advantages to
clients that are increasingly short of resources.
 
  One of the key elements of Mastech's growth has been its ability to recruit
and deploy, on short notice, experienced IT professionals on a worldwide
basis. As of September 30, 1997, the Company employed approximately 2,400 IT
professionals, over 1,500 of whom were in the U.S., with the remainder in
Canada, Europe, the Middle East, Singapore, Japan, India and Australia. To
support the Company's growth and to meet the increased demand for IT
professionals, the Company has embarked on an aggressive recruiting strategy,
designed to significantly increase the number of IT professionals hired. The
Company is also establishing a network of training centers in which it trains
new recruits in value-added technologies such as PeopleSoft, Oracle
Applications, Java/HTML and Year 2000 solutions.
 
  In 1995, the Company began marketing its services in key international
markets to meet the large and growing demand for IT services overseas and to
serve its client base of large multinational corporations that need support on
a global basis. In addition to offices in the U.S., the Company maintains
international offices in Toronto, Singapore, London, Sydney, Tokyo, Amsterdam
and the Middle East. As a result of the Company's expanding international
operations, as of September 30, 1997, it had over 470 employees working with
over 90 clients outside the U.S.
 
  To provide cost advantages to clients that are increasingly short of
resources, Mastech is investing in an extensive offshore software development
infrastructure in India, including three state-of-the-art software development
centers. The center in Bangalore, India has been operational for over a year
and is conducting over 30 engagements for Mastech clients in the U.S. and
Canada. Two additional centers are under development in
 
                                      23
<PAGE>
 
Pune and Madras, India. The Company believes that this offshore
infrastructure, with the ability to accommodate 1,500 IT professionals when
complete, will represent one of the largest offshore presences in the
industry.
 
THE IT SERVICES INDUSTRY
 
 OVERVIEW
 
  The growing worldwide demand for IT services has been driven by the
increasing reliance on IT as a strategic tool for addressing critical business
issues. Intense competition, deregulation, globalization and technological
innovation are accelerating the rate of change in business. Organizations face
constant pressures to improve the quality of products and services, reduce
cost and time to market, improve operating efficiencies and strengthen
customer relationships. In order to achieve these objectives, organizations
are re-engineering their business processes and improving the information
systems which enable and support the re-engineered processes. Simultaneously,
rapid advances in technology have accelerated demand for the transition from
mainframe to client/server architectures, from separate systems to enterprise-
wide integrated applications and from internal to inter-enterprise computing.
 
  As a result of the variety and complexity of new technologies, IT
departments must integrate and manage distributed computing environments
consisting of multiple operating systems, databases, programming languages and
networking protocols, and must implement custom and packaged software
applications to support business objectives. As organizations deal with this
complexity, IT departments have also been overwhelmed by the large number of
software applications that need to be rewritten, re-engineered or converted in
order to effect the transition to newer technologies and address the Year 2000
problem. In addition, external economic factors are forcing companies to focus
on core competencies and trim their IT workforce.
 
  Accordingly, to support their growing IT needs, many organizations utilize
experienced third-party IT service providers to assist in the development and
implementation of IT solutions and services. According to industry sources,
the worldwide market for IT services was estimated at $185 billion in 1995,
with a projected market of $292 billion in the year 2000. The U.S. IT services
market is projected to grow from $75 billion in 1995 to $130 billion in the
year 2000.
 
 INDUSTRY TRENDS
 
  The Company believes that the following key industry trends will have a
major influence on the worldwide IT services market:
 
  Growth in ERP Packaged Software. Organizations are increasingly turning to
ERP packaged software applications such as SAP R/3, Oracle Applications, Baan
and PeopleSoft. By customizing and deploying these large, integrated
applications packages, organizations seek to replace, on a global, enterprise-
wide basis, their aging legacy applications, which have limited functionality
and integration. However, the implementation of these packages is a major
undertaking and requires highly specialized skill sets and functional
expertise, which are in short supply.
 
  The Year 2000 Problem. As the millennium approaches, many existing computer
applications will malfunction because they are unable to process dates
properly beyond December 31, 1999. A typical organization may have thousands
of programs which need to be analyzed, altered and tested, making the task
enormously time and labor intensive. Industry sources estimate that the cost
worldwide to fix this problem (including in-house costs) will be between $300
billion and $600 billion.
 
  Shortage of IT Professionals. There is a growing shortage of IT
professionals in developed countries, particularly the U.S., Western Europe
and Japan. The Information Technology Association of America has estimated a
current shortage of 190,000 IT professionals in the U.S. alone and indicated
that this shortage is exacerbated by a decreasing number of students
graduating from U.S. universities with sufficient skills to fill the
 
                                      24
<PAGE>
 
growing demand for IT professionals. Problems associated with the Year 2000
are expected to compound the shortage, as qualified IT professionals are
diverted from normal development activities to handle more urgent Year 2000
compliance issues.
 
  International Demand for IT Services. Organizations in countries other than
the U.S. are making the transition from mainframes to client/server
architectures, implementing integrated applications packages and addressing
the Year 2000 problem. The Company believes that many of these organizations
have lagged behind U.S. companies in these areas and are now aggressively
adopting new technologies. As a result, several of these markets are
experiencing faster growth than the U.S. market. For example, according to an
industry source, growth in the IT services industry through the year 2000 will
be 19.6% in the Asia/Pacific region, compared to 11.5% in the U.S.
 
  Growth in Offshore Software Development. In light of the large and growing
backlog of applications development projects, the shortage of qualified IT
professionals in developed countries and the rising costs of applications
development and support, an increasing number of organizations are turning to
offshore software development. This approach offers a number of benefits,
including lower costs, faster delivery, more flexible scheduling and access to
a larger pool of skilled IT professionals. India is widely acknowledged as the
leader in offshore software development due to its large English-speaking
software talent pool, low labor costs and investments in technical education
and telecommunications. Many large organizations, including AT&T, Citicorp,
Digital Equipment, General Electric, Hewlett-Packard, IBM, Motorola and Oracle
are using offshore software development in India. The Gartner Group predicts
that over the next two years many organizations will spend a significant
percentage of their legacy budgets for offshore projects. The Company believes
that the demand for offshore software development is further increased by the
Year 2000 problem, solutions for which are expected to be highly labor-
intensive while providing little incremental benefit and, therefore, require a
low-cost solution.

  The Company believes that these strategies, combined with the breadth of its
technical and business experience and knowledge of global markets, position it
to capitalize on market opportunities for growth. Each of the foregoing
strategies is discussed in more detail below:
 
  Provide a Broad Range of Applications Solutions. Mastech provides its
clients with a single source for a broad range of IT applications solutions
and services, including client/server design and development,
conversion/migration services, Year 2000 services, ERP package implementation
services, Internet/intranet services and applications maintenance outsourcing.
These services are provided in a wide variety of computing environments, and
use leading technologies, including client/server architectures, object-
oriented programming languages and tools, distributed database management
systems and the latest networking and communications technologies. In
addition, the Company has developed proprietary SmartAPPS methodologies and
tools to enhance productivity. The Company's broad range of services allows it
to offer clients a single source for IT applications solutions and enables it
to cross-sell services throughout clients' organizations.
 
  Provide ERP Package Implementation Services. The Company leverages its
client/server expertise by providing ERP package implementation services for
Oracle Applications, Baan, PeopleSoft and SAP R/3, including project
management, customization, integration, migration, database design and
administration, systems support and training. The Company's status as an
Oracle, Baan and PeopleSoft business partner results in direct industry
referrals and enhanced industry recognition and enables the Company to broaden
its client base,
 
                                      26

maintain technological leadership and increase its competitiveness. In order
to meet the growing demand for ERP professionals, the Company recently
established an ERP Applications Training Center in Bombay, which currently
graduates over 20 trained professionals each month, and intends to set up
similar training centers in other cities in the U.S., Canada and India.
 
  Offer a Complete Range of Year 2000 Services. The Company's Year 2000
service line offers impact assessment, project planning, conversion, testing
and implementation services. The Company's strategy is to convert Year 2000
projects into applications maintenance outsourcing and client/server migration
engagements. Mastech has developed a proprietary conversion methodology, known
as SmartAPPS, that can be adapted for various types of programming language
translation. SmartAPPS automates a high percentage of the activity required
for impact analysis and conversion of programming languages such as MVS COBOL.
Developed by the Company's Advanced Technology Group, the SmartAPPS toolset
uses compiler technology to incorporate natural language-based analysis and
transformations, and is designed and built with object-oriented languages,
providing generic capabilities that have the potential to address other
conversion and translation needs.
 
  Accelerate Global Recruitment of High-Quality IT Professionals. Mastech's
growth has been driven by its ability to recruit and deploy, on short notice,
experienced IT professionals on a worldwide basis. In addition to the U.S.,
the Company recruits in India, Canada, the U.K., Singapore, Australia, the
Philippines, Russia, Bulgaria, Brazil, Sri Lanka and South Africa. The Company
maintains a proprietary database of qualified candidates, enabling it to
respond to changing manpower requirements rapidly, as well as to manage and
increase the efficiency of its workforce. The Company advertises in leading
newspapers and trade magazines and has dedicated recruiters in its offices
worldwide. The Company also recruits recent college graduates, provides them
with training in key technologies and deploys them on client engagements.
 
  Continue Expansion in Key Global Markets. Mastech has demonstrated the
scalability of its business model in the United States by increasing its
revenues from $13.5 million in 1991 to $123.4 million in 1996 and $135.8
million for the nine months ended September 30, 1997. The Company's strategy
is to capitalize on the large and growing demand for IT services overseas and
to leverage its client base of large multinational corporations that need
support on a global basis. The Company opened offices in Canada and Singapore
in 1995, in Japan and the U.K. in 1996 and in Australia, the Netherlands and
the Middle East during the first nine months of 1997. The Company has
successfully grown these international operations to over 470 employees. The
Company also plans to open offices in South Africa and Latin America.
 
  Leverage Centralized "Low-Overhead" Model. Mastech has adopted a centralized
approach to selling and servicing its worldwide client base, instead of using
a large network of branch offices to serve clients in local markets. During
1997, the Company has served approximately 385 clients in 44 states from its
headquarters in Pittsburgh and offices in Washington, D.C., Dallas and San
Francisco. Similarly, the Company's office in Toronto serves clients
throughout Canada. This strategy has provided the Company with the benefits of
a national presence without the costs associated with a large network of
branch offices.
 
  Continue Expansion of Offshore Software Development Capability. To meet the
growing worldwide demand for offshore software development services, Mastech
is continuing to invest, through its Mascot Systems subsidiary, in an
extensive offshore infrastructure in India, including three state-of-the-art
software development centers. When completed, these centers will have
approximately 130,000 square feet of total space and the capacity to
accommodate approximately 1,500 IT professionals. The first center, located in
Bangalore (known as India's "Silicon Valley"), has been operational for over a
year and is conducting over 30 engagements for clients in the U.S. and Canada.
This center is connected via secure, high-speed satellite links to the
Company's headquarters and client sites. Two additional centers in Pune and
Madras, India are planned to be operational in the first quarter of 1998. The
Company believes that this offshore infrastructure, when complete, will be one
of the largest in the industry and will differentiate it from those
competitors who either have no offshore capability or depend on independent
contractor relationships to offer such services.

SERVICES
 
  Mastech provides its clients with a single source for a broad range of IT
applications solutions and services, including: (i) client/server design and
development; (ii) conversion/migration services; (iii) Year 2000 services;
(iv) ERP package implementation services; (v) Internet/intranet services; and
(vi) applications maintenance outsourcing. These services are provided in a
variety of computing environments and use leading technologies including
client/server architectures, object-oriented programming languages and tools,
distributed database management systems, groupware and the latest networking
and communications technologies. In addition, the Company has developed
proprietary SmartAPPS methodologies and tools to enhance productivity.
 
  Historically, a substantial majority of the Company's projects have been
client-managed. On client-managed projects, Mastech provides professional
services as a member of the project team on a time-and-materials basis. On
Mastech-managed projects, Mastech assumes responsibility for project
management and bills the client on a time-and-materials or fixed-price basis.
The number of Mastech-managed projects is increasing and these projects
generally carry higher profit margins.
 
  The Project Control Office ("PCO"), located in the Company's headquarters,
provides project management oversight for all North American client
engagements. For offshore projects, the PCO is the point of contact during
client business hours, establishing a clear line of communication with the
project teams in India and the U.S. Mastech uses a proprietary Lotus Notes-
based Global Project Tracking System to facilitate project management and
control. The Company also utilizes PC conferencing tools to conduct "virtual"
meetings.
 
  The Company offers many of its services through an existing offshore
software development center in Bangalore, India which is connected via secure,
high-speed satellite links to the Company's headquarters and client sites.
Mastech is increasing its offshore capacity by developing additional offshore
software development centers in Pune and Madras, India. Offshore software
development offers clients certain advantages as compared to domestic
development, including: (i) significant cost savings; (ii) faster delivery, as
larger teams can be deployed; (iii) virtual 24-hour project schedules, due to
the time difference between North America and India; and (iv) improved access
to a large pool of IT professionals.

 ADDITIONAL SERVICES--EDUCATION AND TRAINING
 
  Mastech's Education and Training Department provides employees with basic
and advanced courses in key technologies such as Oracle, PowerBuilder,
VisualBasic, Java and ERP packages including Oracle Applications and Baan.
Mastech is planning to expand its training programs and courseware to offer
them to its clients as a distinct value-added service. The Company has piloted
this service with selected clients and has received positive feedback.
 
SALES AND MARKETING
 
  Mastech sells its services to large and medium-sized organizations through a
direct sales force of over 70 professionals. The Company's sales force is
organized to meet the needs of the marketplace through four primary divisions:
(i) the U.S. Services Division; (ii) the Solutions Division; (iii) the
Enterprise Package Solutions Division; and (iv) the International Division.
Sales directors and representatives in each division are highly incentivized
to cross-sell the services of other divisions.
 
  The U.S. Services Division includes four geographic regions, each of which
is directed by a Regional Director. Each region includes multiple new business
development managers. These individuals use a proprietary database of several
thousand prospects to telemarket Mastech's services nationally. The Company
subsequently sends interested prospective clients a written proposal providing
information about the Company, its approach and methodology, schedules, team
members, pricing and terms. Mastech leverages the mobility of its software
professionals and its cost effective telephone selling model to service all
areas of the U.S. Each geographic region also includes Corporate Account
Managers who are responsible for selling Mastech's services to existing
clients. These managers, Regional Directors and senior management meet
frequently on a direct, face-to-face basis with clients.
 
  The U.S. Services Division also focuses on developing national and global
relationships with major systems integrators such as EDS, IBM, KPMG Peat
Marwick, Ernst & Young and Oracle. Mastech assists these integrators in
meeting their customers' needs by providing specialized technical expertise
and complementary capabilities such as offshore development.
 
  The Solutions Division is responsible for securing and managing Mastech-
managed engagements. This division has a dedicated sales and marketing team
responsible for generating and qualifying leads and developing detailed
project estimates and proposals. This team sells directly to large and medium-
sized organizations and also partners with large systems integrators.
 
 
                                      30
<PAGE>
 
  The Enterprise Package Solutions Division manages engagements and provides
IT professionals trained in ERP package implementation services. This division
works directly with end-user clients and also as partners with both the ERP
software vendors and systems integrators on teamed implementation efforts.
 
  The International Division operates through offices in seven different
countries. Each office is supervised by a Country Manager and supported by
dedicated sales personnel that sell directly to new clients using an approach
similar to the Company's U.S. sales approach. Additionally, these offices
focus on leveraging Mastech's existing relationships with its U.S.-based
multinational clients. These relationships are particularly strong with global
systems integrators and often provide a foundation on which each of Mastech's
international offices can build.
 
  Mastech's marketing organization works closely with the sales organization
to constantly improve results by supporting it with market research to assist
in strategic planning and tactical decision making, trade show selection and
exhibit planning, marketing literature, advertising and public relations
support. The marketing organization develops messages and positioning for such
activities by analyzing market trends and competitors' activities.
 
CLIENTS
 
  Substantially all of the Company's clients are large and medium-sized
organizations. During the nine months ended September 30, 1997, the Company
has provided services to over 475 clients worldwide in a diverse range of
industries. The Company's strategy is to maximize its client retention rate
and secure follow-on engagements by providing high-quality services and client
responsiveness. A significant number of the Company's clients have selected
Mastech on a recurring basis to provide additional services.
 
  The Company is a preferred vendor for several large organizations, including
Associates Bancorp, Bank of America, EDS, IBM Year 2000 Global Services, KPMG
Peat Marwick and Oracle. As a preferred vendor, the Company is one of a
limited number of service providers to these organizations, enabling it to
sell its services more effectively. The Company is aggressively pursuing
additional preferred vendor arrangements in order to obtain new or additional
business from large and medium-sized organizations. These contracts generally
result in lower margins due to negotiated discounts, but are expected to
generate higher revenues with lower selling costs.
 
  Organizations to which the Company has provided, or is providing, services
include:

REPRESENTATIVE ENGAGEMENTS
 
  Examples of the Company's engagements, which are representative of the
nature of its services, are set forth below:
 
   CLIENT/SERVER DESIGN AND DEVELOPMENT: RE-ENGINEERING SOLUTION FOR A
CONSUMER PRODUCTS COMPANY.
 
  Problem. A consumer products company needed to re-engineer its business
processes in order to implement an integrated, enterprise-wide system that
would incorporate high-tech tools such as hand-held computers to allow its
employees to check a customer's account history and produce point-of-sale
invoices.
 
  Solution. Mastech designed and developed an integrated, enterprise-wide
system comprised of 12 different applications using Oracle Designer 2000.
Mastech's engagement team recommended the hardware, software and development
methodology. Mastech's responsibilities included project management, vendor
management, application and database architecture design, analysis and re-
engineering of the enterprise-wide processes implementation, training and
maintenance support.
 
   CONVERSION/MIGRATION: LARGE-SCALE CONVERSION FOR A STATE GOVERNMENT AGENCY.
 
  Problem. A large state government agency in the U.S. needed to convert all
of its applications from a Unisys mainframe to an IBM environment.
 
  Solution. Mastech used a combination of on-site and offshore project teams
to complete the project. Mastech's offshore software development center in
Bangalore, India developed conversion tools to increase productivity by
automating the source language conversion. The offshore team developed eight
conversion tools to manage the conversion of two million lines of code
involving three different source languages, two on-line transaction processing
environments and the conversion from a network database to a relational
database.
 
   ERP PACKAGE IMPLEMENTATION: MIGRATION OF A UTILITY COMPANY'S SYSTEMS TO
ORACLE APPLICATIONS.
 
  Problem. A major utility company needed to reduce costs to remain
competitive in the marketplace. Over the years, it had developed multiple
independent systems on a variety of platforms, resulting in isolated
information that could not be consolidated for an in-depth and accurate
analysis of costs.
 
  Solution. Upon Mastech's recommendation, the utility decided to implement
Oracle Financials and Manufacturing ERP packages to obtain faster access to
critical information, better decision-making capability, improved
understanding of costs using activity-based costing and the ability to compile
information across organizational and functional lines. Mastech specialists
are providing Oracle Financials and Manufacturing expertise to customize and
implement the General Ledger, Inventory and Accounts Payable modules of Oracle
Financials, the Inventory and Purchasing modules of Oracle Manufacturing, and
to develop interfaces between the materials planning system and the Oracle
Applications, data conversion routines and additional functionality.
 
   APPLICATIONS MAINTENANCE OUTSOURCING: OFFSHORE APPLICATION ENHANCEMENT
   AND SUPPORT FOR A LARGE CANADIAN INVESTMENT FIRM.
 
  Problem. One of Canada's largest investment firms needed to maintain its
application systems in a cost-effective manner.
 
  Solution. Mastech used its offshore software development capabilities to
maintain the client's applications. The client was able to obtain the benefits
of on-site development support and coordination, while taking advantage of
Mastech's management and offshore software development and support capability.

   INTERNET/INTRANET SOLUTIONS: A BIG SIX CONSULTING FIRM NEEDED JAVA
   SPECIALISTS TO HELP IT DEVELOP AN INTERNET PRESENCE.
 
  Problem. A Big Six consulting firm wanted to broaden its range of services
through the Internet by developing applications to support the delivery of
content and transactions capability to its entrepreneurial clients.
 
  Solution. Mastech's Java specialists helped analyze, design, prototype and
develop the system by writing VisualBasic modules, JavaScript routines and CGI
scripts. They also evaluated various technologies for transaction processing
monitors and remote automation objects to address issues related to running a
client-server application over the Internet.
 
HUMAN RESOURCES
 
  The Company's success depends in large part on its ability to attract,
develop, motivate and retain highly skilled IT professionals. The Company has
over 90 full-time employees dedicated to recruiting IT professionals and
managing its human resources. The Company recruits in a number of countries,
including India, the U.S., Canada, the U.K., Singapore, Australia, the
Philippines, Russia, Bulgaria, Brazil, Sri Lanka and South Africa. The Company
advertises in leading newspapers and trade magazines. In addition, the
Company's employees are a valuable recruiting tool and are actively involved
in referring new employees and screening candidates for new positions. Mastech
uses a standardized global selection process which includes interviews, tests
and reference checks.
 
  The Company's Resource Managers use a proprietary system to manage the
employees and candidates in the Company's talent pool. This system enables the
Company to quickly identify appropriate IT professionals for various client
engagements. This database, which currently holds profiles on several thousand
IT professionals, catalogs individual technical profiles and stores
information pertaining to each individual's location, availability, mobility
and other factors.
 
  The Company has a focused retention strategy that includes career planning,
training, benefits and an incentive plan. The Company's benefits package
includes Company-subsidized health insurance, group life insurance, a long-
term disability plan, Company-subsidized health club memberships and tuition
reimbursement. The Company intends to continue to use stock options as part of
its recruitment and retention strategy. The Company also has an extensive
training infrastructure. The Company's Education and Training Department
trains employees on a variety of platforms and helps them transition from
legacy to client/server skills by providing cross-platform training in new
technologies. The Company is implementing an intranet to allow its employees
to access its courseware and computer-based training modules via the Internet
so that the training is available to all employees worldwide at their
individual convenience and pace.
 
  Mastech's IT professionals typically have Master's or Bachelor's degrees in
Computer Science or another technical discipline and two to ten years of IT
experience. As of September 30, 1997, the Company had 2,696 employees
comprised of 2,389 IT professionals, 74 sales and marketing personnel and 233
general and administrative personnel. Over 90% of Mastech's IT professionals
are citizens of other countries, with most of those in the U.S. working under
H-1B temporary work permits. See "Risk Factors--Government Regulation of
Immigration." In addition, the Company uses independent contractors to support
client engagements. As of September 30, 1997, the Company had 82 independent
contractors working on client engagements.
 
COMPETITION
 
  The IT services industry is highly competitive and served by numerous
national, regional and local firms, all of which are either existing or
potential competitors of the Company. Primary competitors include participants
from a variety of market segments, including "Big Six" accounting firms,
systems consulting and implementation firms, applications software firms,
service groups of computer equipment companies, general management consulting
firms, programming companies and temporary staffing firms. Many of these
competitors have substantially greater financial, technical and marketing
resources and greater name recognition than the
 
                                      33
<PAGE>
 
Company. In addition, there is a risk that clients may elect to increase their
internal IT resources to satisfy their applications solutions needs. The
Company believes that the principal competitive factors in the IT services
industry include the range of services offered, technical expertise,
responsiveness to client needs, speed in delivering IT solutions, quality of
service and perceived value. The Company believes that it competes favorably
with respect to these factors.
 
INTELLECTUAL PROPERTY RIGHTS
 
  The Company relies upon a combination of nondisclosure and other contractual
arrangements and trade secret, copyright and trademark laws to protect its
proprietary rights and the proprietary rights of third parties from whom the
Company licenses intellectual property. The Company enters into
confidentiality agreements with its employees and limits distribution of
proprietary information. There can be no assurance that the steps taken by the
Company in this regard will be adequate to deter misappropriation of
proprietary information or that the Company will be able to detect
unauthorized use and take appropriate steps to enforce its intellectual
property rights.
 
  Software developed by the Company in connection with a client engagement is
typically assigned to the client. In limited situations, the Company may
retain ownership or obtain a license from its client, which permits Mastech or
a third party to market the software for the joint benefit of the client and
Mastech or for the sole benefit of Mastech.
 
FACILITIES
 
  The Company leases 56,234 square feet of office space in the Pittsburgh
suburb of Oakdale, Pennsylvania which serves as its headquarters. The
Company's senior management, administrative, personnel, human resources and
sales and marketing functions are housed in this facility. This lease expires
on May 31, 2001 and provides for two additional options to extend the lease
for consecutive five-year terms. The Company believes that this location has
sufficient space for its current and anticipated needs through 1997 and is
currently exploring leasing additional space at its headquarters and at other
locations. The Company has sales offices in Washington, D.C., Dallas and San
Francisco.
 
  The Company has sales offices in several countries in order to develop
business internationally. The Company currently leases office space in London,
Singapore, Sydney, Amsterdam, the Middle East, Toronto and Tokyo. These
locations allow the Company to respond quickly to the needs of its
international clients and to recruit qualified IT professionals in these
markets.
 
  Mascot Systems leases one offshore software development facility totaling
approximately 30,000 square feet in Bangalore, India and one recruiting
facility totaling approximately 4,200 square feet. These facilities were
established by Messrs. Wadhwani and Trivedi to deliver the Company's offshore
software development services to the Company's clients worldwide. Mascot
Systems intends to lease from Messrs. Wadhwani and Trivedi two additional
offshore software development centers. These facilities, totaling 100,000
square feet, are located in Pune and Madras, India, and are scheduled for
completion during the first quarter of 1998.
 
LITIGATION
 
  The Company is not a party to any litigation that is expected to have a
material adverse effect on the Company or its business.

(1) The closing price for the Common Stock as reported on the Nasdaq National
    Market on December 31, 1996 (the last day of trading in 1996) was $19.
    Value is calculated on the basis of the difference between the option
    exercise price and $19, multiplied by the number of shares of Common Stock
    underlying the option.
 
EMPLOYEE BENEFIT PLANS
 
  Stock Incentive Plan. The Company has reserved an aggregate of 2,160,000
shares of Common Stock for issuance under the 1996 Stock Incentive Plan (the
"Stock Incentive Plan"), which may be granted to directors, officers and other
employees and consultants of the Company and its subsidiaries. The Stock
Incentive Plan permits: (i) the grant of incentive stock options; (ii) the
grant of non-qualified stock options; (iii) the issuance or sale of Common
Stock with or without vesting or other restrictions ("Stock Grants"); (iv) the
grant of Common Stock upon the attainment of specified performance goals
("Performance Share Awards"); and (v) the grant of stock appreciation rights.
In addition, directors who are not employees or officers of the Company
("Independent Directors") will automatically be eligible for certain grants
under the Stock Incentive Plan, as described below. On and after the date the
Stock Incentive Plan becomes subject to Section 162(m) of the Internal Revenue
Code of 1986, as amended, the maximum number of shares of Common Stock that
may be awarded to any one individual in any calendar year is 200,000 shares.
Since the inception of the Stock Incentive Plan, options have been granted to
247 employees. As of October 15, 1997, 1,253,150 shares were subject to
outstanding options and 903,950 shares remained available for future grants
under the Stock Incentive Plan.
 
  The Stock Incentive Plan is administered by the Board of Directors or by a
committee designated by the Board ("Administrator"). Subject to the provisions
of the Stock Incentive Plan, the Administrator has full power to determine,
from among the persons eligible for grants under the Stock Incentive Plan: (i)
the individuals to whom grants will be granted; (ii) the combination of grants
to participants; and (iii) the specific terms of each grant. Incentive stock
options may be granted only to officers or other employees of the Company or
its subsidiaries, including members of the Board of Directors who are also
employees of the Company or its subsidiaries.
 
  The option exercise price of each option granted under the Stock Incentive
Plan is determined by the Administrator but, in the case of incentive stock
options, may not be less than 100% of the fair market value of the underlying
shares on the date of grant. Incentive stock options may not be exercisable
more than ten years from the date the option is granted. If any employee of
the Company or any subsidiary owns or is deemed to own at the date of grant
shares of stock representing in excess of 10% of the combined voting power of
all classes
 
                                      39
<PAGE>
 
of stock of the Company, the exercise price for incentive stock options
granted to such employee may not be less than 110% of the fair market value of
the underlying shares on that date and the option may not be exercisable more
than five years from the date the option is granted. Upon the exercise of
options, the option exercise price must be paid: (i) in cash; (ii) by delivery
to the Company of a notice of exercise with an irrevocable direction to a
registered broker-dealer to sell a sufficient number of shares and to deliver
the sales proceeds directly to the Company; or (iii) in the sole discretion of
the Administrator, by delivery of shares of Common Stock that have been
previously owned by the optionee for at least six months.
 
  The Board of Directors can terminate or amend the Stock Incentive Plan at
any time, except that no such action may adversely affect any right or
obligation regarding any awards previously made under the Stock Incentive Plan
without the consent of the recipient. In the event of any changes in the
capital structure of the Company, such as a stock dividend or split-up, the
Board of Directors must make equitable adjustments to outstanding unexercised
awards so that the net value of the award is not changed.
 
  Independent Director Options. The Stock Incentive Plan provides for the
automatic grant of non-qualified stock options to Independent Directors. Under
such provisions, options to purchase 15,000 shares of Common Stock are granted
to each non-employee director upon such director's initial appointment or
election to the Board. The option exercise price for options granted to
Independent Directors under the Stock Incentive Plan will equal the then fair
market value of the underlying Common Stock. Options granted to Independent
Directors under the foregoing provisions will vest in annual installments over
three years commencing on the first anniversary of the date of grant and will
expire ten years after grant, subject to earlier termination if the optionee
ceases to serve as a director.
 
  401(k) Plan. The Company maintains a 401(k) defined contribution plan (the
"401(k) Plan"). All employees of the Company who have completed six months of
employment are eligible to participate in the 401(k) Plan, pursuant to which
each participant may contribute up to 15% of eligible compensation (up to a
statutorily prescribed annual limit of $9,500 in 1997). The Company does not
currently match contributions made by employees to the 401(k) Plan. All
amounts contributed by employee participants and earnings on these
contributions are fully vested at all times. Employee participants may elect
to invest their contributions in various established funds.
 
EMPLOYMENT AGREEMENTS
 
  The Company has entered into substantially identical employment contracts
with Messrs. Wadhwani and Trivedi, pursuant to which each of them serves as an
executive officer of the Company at an annual base salary of not less than
$300,000, plus an annual bonus of up to $200,000 if performance goals to be
established by the Compensation Committee of the Board of Directors are met.
The agreements have a term of 24 months and automatically extend for one month
at the end of each month unless either party gives notice of their intention
to terminate the agreement at the end of the term. The agreements provide that
upon termination of employment by the Company other than for cause (as defined
in the agreements) or death, disability or retirement, the Company shall pay
the officer a lump sum amount equal to the amount the executive would have
been paid, based upon his base salary at the time of termination, if such
executive had remained an employee for the full term of his contract, plus
shares of Common Stock having a value equal to the value of the executive's
vested stock options and stock appreciation rights. In such event, the Company
will also provide health insurance for the executive for the remainder of his
life at the level in effect for other executives prior to his termination for
the remainder of the term. In the event the executive is terminated due to a
disability, the Company will continue to pay for three years the executive's
salary and an amount equal to his bonus in the year prior to his termination,
reduced by any amounts paid to the executive under the Company's disability
plan. Under the agreements, the Company agrees to indemnify the executive to
the full extent not prohibited by law for liabilities he incurs in his
capacity as a director, officer or controlling person of the Company. Under
the agreements, the executives agree to a noncompetition covenant during the
term of the agreement and for one year after the termination of their
employment for cause and to nonsolicitation and nondisclosure covenants during
the term of the agreement and for one year after the termination of their
employment for any reason.
 
                                      40
<PAGE>
 
  The other Named Executive Officers are parties to employment agreements
which outline their responsibilities and provide generally for base salary
plus annual incentive bonuses. These executives are "at- will" employees of
the Company and can be terminated by the Company with or without cause or they
may resign. Under the agreements, the executives are entitled to three months'
salary continuation if they are terminated by the Company without cause
generally, and to six months' salary continuation if they are terminated by
the Company without cause during the 90 days following the sale of the Company
to a third party. The employment agreements also contain confidentiality
provisions and noncompetition and nonsolicitation covenants.
 
  In October 1996, the Company entered into an agreement with Steven Shangold,
the Company's Vice President of U.S. Sales and Marketing, pursuant to which
the Company agreed to pay Mr. Shangold, as compensation for past services, an
amount equal to the value of 109,200 shares of Common Stock. One-half of the
foregoing payment was made promptly following the closing of the Company's
initial public offering in cash at the election of Mr. Shangold. The remaining
half was paid in the form of 54,600 shares of restricted Common Stock which
will vest on June 30, 1998. If Mr. Shangold voluntarily leaves the employment
of the Company or is terminated by the Company for cause before that date, the
shares of restricted Common Stock will be forfeited. If Mr. Shangold is
terminated without cause, upon the sale of the Company or upon death before
that date, the shares of restricted Common Stock will vest on a pro rata
basis.

                             CERTAIN TRANSACTIONS
 
  Mascot Systems, an Indian corporation, is a wholly owned subsidiary of the
Company. The Company uses Mascot Systems to perform offshore software
development projects. During 1996, Mascot Systems billed the Company
approximately $205,000 for the services it provided to the Company. Prior to
the initial public offering in December 1996, Mascot Systems was controlled by
Messrs. Wadhwani and Trivedi.
 
  The Company purchased the shares of Mascot Systems held by Messrs. Wadhwani
and Trivedi for $170,000, which price was based upon an independent valuation
of that interest. The purchase price was paid from the Company's working
capital. In transactions completed shortly after the Company's initial public
offering, the Company also purchased the minority shares of Mascot Systems,
which were previously held by relatives of Messrs. Wadhwani and Trivedi.
 
  Mascot Systems is currently operating one and constructing two other
offshore software development facilities in the cities of Bangalore, Pune and
Madras, India, respectively. For the year ended December 31, 1996, the Company
advanced Mascot Systems $865,000 towards buildout and other costs of setting
up and operating these facilities. Upon completion of the acquisition of
Mascot Systems by the Company, the aggregate amount of these advances was
eliminated in consolidation.
 
  Scott Systems, an Indian corporation, is a wholly owned subsidiary of the
Company. The Company uses Scott Systems to recruit and train IT professionals
in India. Prior to the Company's initial public offering, Scott Systems was an
Indian corporation indirectly controlled by Messrs. Wadhwani and Trivedi
through a Pennsylvania corporation known as SWAT Systems Corporation ("SWAT").
The Company entered into a merger agreement with SWAT pursuant to which SWAT
was merged with and into Mastech shortly before the completion of the initial
public offering. Messrs. Wadhwani and Trivedi received nominal consideration
in this transaction. The Company also entered into an agreement to purchase
the minority shares of Scott Systems, some of which were held by relatives of
Messrs. Wadhwani and Trivedi, for $26,000.
 
  Mascot Systems leases from Messrs. Wadhwani and Trivedi the office space for
the offshore software development facility in Bangalore, India. The
acquisition of the real estate and the construction of this office building
(but not the buildout of the office space) was financed entirely by Messrs.
Wadhwani and Trivedi out of personal funds. Specifically, Mascot Systems
leases approximately 4,200 square feet of office space on one floor of an
office building located in Bangalore, which floor is owned by Messrs. Wadhwani
and Trivedi. The lease has a three-year term expiring in January 1998 and the
rent is approximately $7,000 per year. Mascot Systems also leases a 32,500
square foot office building located in Bangalore from Messrs. Wadhwani and
Trivedi. This lease has a five-year term expiring in October 2001 and the rent
is approximately $110,000 per year. The offshore software development
facilities located in Pune and Madras, India are expected to be operational
sometime during the first quarter of 1998. Mascot Systems expects to enter
into two additional leases with Messrs. Wadhwani and Trivedi for these
facilities. The facility in Pune is a 35,000 square foot office building and
the facility in Madras is a 65,000 square foot office building.
 
  Scott Systems leases, for its training facilities, approximately 2,100
square feet of office space on one floor of an office building located in
Mumbai (Bombay), India. The leased space is divided into five separately owned
suites owned individually by Messrs. Wadhwani and Trivedi. The leases have a
one-year term expiring in March 1998 and the aggregate rent is $20,000 per
year. Scott Systems also leases further office space of approximately 900
square feet on another floor in the same office building which is owned by
Messrs. Wadhwani and Trivedi. The lease has a one-year term expiring in
October 1998 and the rent is $6,000 per year. Scott Systems also leases a
portion of the Pune facility from Messrs. Wadhwani and Trivedi. This lease
covers 7,500 square feet and has a three-year term expiring in September 2000.
The rent is $26,000 per year.
 
  The Company believes that the terms of the leases described above are no
less favorable to the Company than could be obtained from unrelated third
parties.

  During the first six months of 1996, the Company was a party to three real
property leases with Messrs. Wadhwani and Trivedi for residential space near
its Pittsburgh headquarters. The leased premises included two condominium
units and one single family residence. These leased premises were used to
accommodate out-of-town IT professionals temporarily working at the Company's
Pittsburgh facility or in transit to another working location. The aggregate
monthly rental for these leased premises was $3,000 per month plus the
operating costs of the premises. The Company terminated these leases in the
second quarter of 1996. Various residential properties are owned by Messrs.
Wadhwani and Trivedi in India and will be leased by the Company for similar
purposes.
 
  As an S corporation prior to the initial public offering, the net income of
the Company was attributed, for federal (and some state) income tax purposes,
directly to the Company's shareholders rather than to the Company. During
1996, the Company from time to time paid the corresponding income taxes due on
these amounts on behalf of Messrs. Wadhwani and Trivedi in the form of
interest-free advances which they later repaid. The highest aggregate amounts
of advances outstanding to Mr. Wadhwani and the Wadhwani Family Qualified
Subchapter S Trust during 1996 and for the nine months ended September 30,
1997 were $1.7 million and $86,000, respectively. The highest aggregate
amounts of advances outstanding to Mr. Trivedi during 1996 and for the nine
months ended September 30, 1997 were $1.7 million and $86,000, respectively.
 
  Prior to the closing of the initial public offering, the Company and the
Selling Shareholders entered into an agreement whereby the Selling
Shareholders agreed to cause the Company to terminate its S-corporation
election effective December 16, 1996. The Company agreed to indemnify the
Selling Shareholders for the amount of any increase in taxable income
allocable to them in the event of any audit of the Company's tax returns.
 
  Prior to the closing of the initial public offering, the Board of Directors
of the Company adopted a resolution requiring all future transactions,
including any loans from the Company to its officers, directors, principal
shareholders or affiliates, to be approved by a majority of the Board of
Directors, including a majority of the independent and disinterested members
of the Board of Directors or, if required by law, a majority of the
disinterested shareholders, and requiring such transactions to be on terms no
less favorable to the Company than could be obtained from unaffiliated third
parties.

                         DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
  The authorized capital stock of the Company consists of 100,000,000 shares
of Common Stock, par value $.01 per share, and 20,000,000 shares of Preferred
Stock, without par value. The following description of the capital stock of
the Company is a summary, and as such, it does not purport to be complete and
is subject, and qualified in its entirety by reference to, the more complete
descriptions contained in: (i) the Articles of Incorporation of the Company,
as amended (the "Articles"), and the Bylaws of the Company, as amended (the
"Bylaws"), copies of each of which are incorporated by reference as exhibits
to the Registration Statement of which this Prospectus is a part; and (ii) the
certificate of designation relating to any series of Preferred Stock that may
be established by the Board of Directors. The Company currently has
outstanding 21,657,500 shares of Common Stock and no shares of Preferred
Stock. On October 24, 1997, the Company had 66 holders of record of the Common
Stock.
 
COMMON STOCK
 
  The Company is authorized to issue up to 100,000,000 shares of Common Stock.
Subject to the rights and preferences that may be applicable to any
outstanding Preferred Stock, the holders of Common Stock are entitled to
receive dividends, when, if and as declared by the Board of Directors of the
Company.
 
  The holders of Common Stock are entitled to one vote per share on all
matters to be voted upon by shareholders. Shareholders do not have cumulative
voting rights in the election of directors, meaning that the holders of a
majority of the shares entitled to vote in any election of directors may elect
all of the directors standing for election. The Bylaws require shareholders
desiring to either nominate persons for election as a director or present
matters for business at a shareholders meeting to give advance notice of such
nominations and/or matters to the Company.
 
  Generally, whenever any corporate action is to be taken by vote of the
shareholders of the Company, or by vote of a class of such shareholders of the
Company, it shall be authorized upon receiving the affirmative vote of a
majority of the votes cast by such shareholders, or by such class of
shareholders, entitled to vote thereon. The Articles, however, in addition
require the approval of at least 66 2/3% of the votes cast by shareholders of
the Company, voting together as a single class, for the following: (i) the
approval of a fundamental change under the Pennsylvania Business Corporation
Law of 1988, as amended ("PBCL"), including amendments of the Articles, a
merger or consolidation of the Company for which shareholder approval is
required by law, share exchanges, the sale or other disposition of all or
substantially all of the assets of the Company or a division of the Company,
and the voluntary dissolution and winding up of the Company ("Fundamental
Transactions"), unless any such Fundamental Transaction is unanimously
approved by all the directors of the Company; and (ii) the amendment of the
Bylaws unless any such amendment is unanimously approved by all the directors
of the Company. The Articles provide that the shareholders may remove any
director, any class of directors or the entire Board of Directors without
cause by the vote of 66 2/3% of the votes cast by shareholders entitled to
vote thereon. The Articles permit shareholder action to be taken by the
written consent of the shareholders entitled to cast the minimum number of
votes that would be necessary to authorize the action at a meeting at which
all shareholders entitled to vote thereon are present and voting.
 
  The Articles provide that the Board of Directors shall consist of five
persons and that the Board shall be divided into three classes of directors,
each class as nearly equal in number as possible, with one class being elected
each year for a three-year term. The classification of the Board helps to
ensure continuity of corporate leadership and policy; however, it also has the
effect of making it more difficult for a person to acquire control of the
Company's Board of Directors because at least two annual meetings are
necessary to effect a change in a majority of the Company's directors.
Further, the Articles provide that the approval of at least four of the
directors is required for Board action.

  In the event of a liquidation, dissolution or winding up of the Company, the
holders of Common Stock are entitled to share ratably in all assets remaining
after the payment of all liabilities of the Company and subject to the
liquidation preferences of any outstanding Preferred Stock. The Common Stock
does not carry preemptive rights, is not redeemable, does not have any
conversion rights, is not subject to further calls and is not subject to any
sinking fund provisions. The outstanding shares of Common Stock are and the
shares offered by the Company in this offering will be, when issued and paid
for, fully paid and nonassessable. Except in certain circumstances as
discussed below under "Certain Provisions Affecting Control of the Company,"
the Common Stock is not subject to discriminatory provisions based on
ownership thresholds.
 
  The rights, preferences and privileges of holders of Common Stock are
subject to, and may be adversely affected by, the rights of the holders of
shares of any series of Preferred Stock which the Company may designate and
issue in the future. See "Description of Capital Stock--Preferred Stock."
 
PREFERRED STOCK
 
  The Company is authorized to issue up to 20,000,000 shares of Preferred
Stock. The Board of Directors is authorized, subject to any limitations
prescribed by law, without further shareholder approval, to issue such shares
of Preferred Stock in one or more series, with such rights, preferences,
privileges and restrictions, including voting rights, dividend rights,
conversion rights, redemption privileges and liquidation preferences, as shall
be established by the Board of Directors at the time of issuance.
 
  The issuance of Preferred Stock by the Board of Directors could adversely
affect the rights of holders of Common Stock. For example, the issuance of
shares of Preferred Stock could result in securities outstanding that would
have preference over the Common Stock with respect to dividends and in
liquidation and that could (upon conversion or otherwise) enjoy all of the
rights of the Common Stock.
 
  The authority possessed by the Board of Directors to issue Preferred Stock
could potentially be used to discourage attempts by third persons to obtain
control of the Company through merger, tender offer, proxy or consent
solicitation or otherwise, by making such attempts more difficult to achieve
or more costly. The Board of Directors may issue Preferred Stock without
shareholder approval and with voting rights that could adversely affect the
voting power of holders of Common Stock. There are no agreements or
understandings for the issuance of Preferred Stock, and the Company has no
plans to issue any shares of Preferred Stock. See "Risk Factors--Possible
Issuances of Preferred Stock."
 
CERTAIN PROVISIONS AFFECTING CONTROL OF THE COMPANY
 
  General. Certain provisions of the Company's Articles and the PBCL operate
with respect to extraordinary corporate transactions, such as mergers,
reorganizations, tender offers, sales or transfers of substantially all of the
Company's assets or the liquidation of the Company, and could have the effect
of delaying or making more difficult a change in control of the Company in
certain circumstances.
 
  Certain Provisions of the Articles. The Articles provide, among other
things, that Fundamental Transactions and Bylaw amendments must be approved by
at least 66 2/3% of the votes cast by shareholders of the Company, unless the
transaction or amendment is unanimously approved by all of the directors of
the Company. This provision is intended to require that Fundamental
Transactions and Bylaw amendments have either the unanimous mandate of the
Company's Board of Directors, who are statutorily charged in the first
instance with managing the business and affairs of the corporation, or the
support of a substantial percentage of the corporation's shareholders. This
provision, however, makes it more difficult to obtain approval of a
Fundamental Transaction that is approved by a majority but not all of the
directors. Further, the holders of 33 1/3% or more of the shares cast on a
Fundamental Transaction can effectively block the transaction by voting
against it. As a result of this provision, a Fundamental Transaction or Bylaw
amendment that is supported by a majority of the Company's directors and by
the holders of a majority of the outstanding voting shares of the Company
 
                                      46
<PAGE>
 
may not be approved. Upon completion of this offering, Messrs. Wadhwani and
Trivedi will beneficially own approximately 63.4% of the Common Stock and have
voting power over 44.3% of the Common Stock.
 
  Certain Provisions of the PBCL. The Company is governed by a set of
interrelated provisions of the PBCL which are designed to support the validity
of actions taken by the Board of Directors in response to takeover bids,
including specifically the Board's authority to "accept, reject or take no
action" with respect to a takeover bid, and permitting the unfavorable
disparate treatment of a takeover bidder. Another provision of the PBCL gives
the directors broad discretion in considering the best interests of the
corporation, including a provision which permits the Board, in taking any
action, to consider various corporate interests, including employees,
suppliers, clients and communities in which the corporation is located, the
short and long-term interests of the corporation, and the resources, intent
and conduct of any person seeking to acquire control of the corporation. These
provisions may have the effect of making more difficult and thereby
discouraging attempts to acquire control of the Company in a transaction that
the Board determines not to be in the best interests of the Company.
 
  The Company has elected to opt-out of certain antitakeover provisions of the
PBCL, including: (i) provisions which prohibit certain business combinations
(as defined in the PBCL) involving a corporation that has voting shares
registered under the Exchange Act and an "interested shareholder" (generally
defined to include a person who beneficially owns shares representing at least
20% of the votes that all shareholders would be entitled to cast in an
election of directors of the corporation) unless certain conditions are
satisfied or an exemption is applicable; (ii) provisions concerning a
"control-share acquisition" in which the voting rights of certain shareholders
of the corporation (specifically, a shareholder who acquires 20%, 33 1/3% or
50% or more of the voting power of the corporation) are conditioned upon the
consent of a majority vote at a meeting of the independent shareholders of the
corporation after disclosure by such shareholder of certain information, and
with respect to which such shareholder is effectively deprived of voting
rights if consent is not obtained; (iii) provisions pursuant to which any
profit realized by a "controlling person or group," generally defined as a 20%
beneficial owner, from the disposition of any equity securities within twenty-
four months prior to, and eighteen months succeeding, the acquisition of such
control is recoverable by the corporation; (iv) provisions pursuant to which
severance payments are to be made by the corporation to any eligible employee
of a covered corporation whose employment is terminated, other than for
willful misconduct, within ninety days before, or twenty-four months after, a
control-share acquisition; and (v) provisions pursuant to which any holder of
voting shares of a registered corporation who objects to a "control
transaction" (generally defined as the acquisition by a person or group (the
"controlling person or group") that would entitle the holders thereof to cast
at least 20% of the votes that all shareholders would be entitled to cast in
an election of the directors of the corporation) is entitled to make a written
demand on the controlling person or group for payment of the fair value of the
voting shares of the corporation held by the shareholder. Given the ownership
structure of the Company after this offering, the Company's Board of Directors
believed that there was a risk that one or more of these provisions could be
inadvertently triggered by the normal activities of the Company and its
principal shareholders and that, therefore, it was in the best interests of
the Company to opt-out of these provisions.
 
TRANSFER AGENT AND REGISTRAR
 
  The transfer agent and registrar for the Common Stock is ChaseMellon

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Upon completion of this offering, the Company will have 23,457,500 shares of
Common Stock outstanding. See "Capitalization." Of these shares, the 3,000,000
shares sold in this offering and the 5,520,000 shares issued in the Company's
initial public offering will be freely tradable without restriction or further
registration under the Securities Act, except that any shares purchased by
"affiliates" of the Company in the public market, as that term is defined
under the Securities Act ("Affiliates"), may generally only be sold in
compliance with the limitations of Rule 144 described below. In addition,
1,253,150 shares of Common Stock (327,052 of which become exercisable on or
before December 31, 1997) are issuable upon the exercise of outstanding stock
options, which shares have been registered by the Company under the Securities
Act and after issuance upon exercise will be freely tradable without
restriction. Of the remaining shares of Common Stock, 14,934,600 are
restricted securities (the "Restricted Shares") within the meaning of Rule 144
under the Securities Act, and may not be sold in the absence of registration
under the Securities Act unless an exemption from registration is available,
including the exemption offered by Rule 144. Of these Restricted Shares,
14,880,000 will be subject to a lock-up period expiring 90 days after the date
of this Prospectus (the "Lock-Up Period"). Beginning after the expiration of
the Lock-Up Period (or earlier upon the prior written consent of Donaldson,
Lufkin & Jenrette Securities Corporation), 14,880,000 of the Restricted Shares
may be sold in the public market subject to Rule 144 under the Securities Act,
except for 4,487,392 shares held in family trusts established by Messrs.
Wadhwani and Trivedi which may not be sold prior to November 30, 1998 pursuant
to the terms of a shareholders agreement with the Company.
 
  In general, under Rule 144 of the Securities Act as currently in effect, a
person (or persons whose shares are aggregated) who has beneficially owned
Restricted Shares for at least one year, including a person who may be deemed
an Affiliate of the Company, may sell within any three-month period a number
of shares of Common Stock that does not exceed the greater of 1% of the then
outstanding shares of Common Stock of the Company (234,576 shares after giving
effect to this offering) or the average weekly trading volume of the Common
Stock as reported through the Nasdaq National Market during the four calendar
weeks preceding such sale. Sales under Rule 144 are subject to certain
restrictions relating to manner of sale, notice and the availability of
current public information about the Company. In addition, under Rule 144(k)
of the Securities Act, a person who is not an Affiliate of the Company at any
time 90 days preceding a sale, and who has beneficially owned shares for at
least two years, would be entitled to sell such shares immediately following
this offering without regard to the volume limitations, manner of sale
provisions or notice or other requirements of Rule 144.
 
REGISTRATION RIGHTS
 
  Pursuant to terms of a Shareholders Agreement, at any time after December
17, 1997, Messrs. Wadhwani and Trivedi (and certain transferees including
members of their families and trusts and other entities controlled by them)
each have the right, subject to certain restrictions set forth in the
Shareholders Agreement, to require the Company to register under the
Securities Act the Common Stock owned by such holders at the Company's expense
on no more than two occasions. The Company is obligated to use its best
efforts to qualify for registration of securities on Form S-3 under the
Securities Act. After the Company has qualified for the use of Form S-3,
Messrs. Wadhwani and Trivedi have the right to an unlimited number of
registrations on such form; the Company is not, however, required to effect a
registration on a Form S-3 more than once in any six-month period. Also
pursuant to the Shareholders Agreement, if the Company proposes to register
any of its Common Stock under the Securities Act for sale to the public,
Messrs. Wadhwani and Trivedi, subject to any lock-up agreements entered into
by Messrs. Wadhwani and Trivedi, will have unlimited piggyback registration
rights at the Company's expense, subject to certain restrictions set forth in
the Shareholders Agreement. In addition, the Company agrees to indemnify
Messrs. Wadhwani and Trivedi against certain liabilities, including
liabilities under the Securities Act, that they may incur in connection with
this offering and any offering governed by the Shareholders Agreement. The
registration rights granted to Messrs. Wadhwani and Trivedi under the
Shareholders Agreement are not exclusive and the Company could determine to
register shares owned by Messrs. Wadhwani and Trivedi other than pursuant to
the Shareholders Agreement. The registration rights granted to Messrs.
Wadhwani and Trivedi will be subject to the lock-up agreement which will
restrict their ability to exercise their registration rights during the Lock-
Up Period.

  The Company can make no prediction as to the effect, if any, that market
sales of shares of Common Stock or the availability of shares for sale will
have on the market price prevailing from time to time. Nevertheless, sales of
significant numbers of shares of the Common Stock in the public market, could
adversely affect the market price of the Common Stock and could impair the
Company's future ability to raise capital through an offering of its equity
securities. See "Risk Factors--Shares Eligible for Future Sale."

  The Underwriting Agreement provides that the obligations of the several
Underwriters to purchase and accept delivery of the shares of Common Stock
offered hereby are subject to the approval by their counsel of certain legal
matters and to certain other conditions. The Underwriters are obligated to
purchase and accept delivery of all the shares of Common Stock offered hereby
(other than those covered by the over-allotment option described below) if any
are purchased.
 
  The Underwriters initially propose to offer the shares of Common Stock in
part directly to the public at the price to the public set forth on the cover
page of this Prospectus and in part to certain dealers (including the
Underwriters) at such price less a concession not in excess of $0.91 per
share. The Underwriters may allow, and such dealers may re-allow to certain
other dealers, a concession not in excess of $0.10 per share. After this
offering, the public offering price and other selling terms may be changed by
the Representatives at any time without notice.
 
  The Selling Shareholders have granted to the Underwriters an option,
exercisable within 30 calendar days after the date of the Underwriting
Agreement, to purchase from time to time, in whole or in part, up to an
aggregate of 450,000 additional shares of Common Stock at the public offering
price set forth on the cover page of this Prospectus, less the underwriting
discounts and commissions. The Underwriters may exercise such option solely to
cover over-allotments, if any, made in connection with this offering. To the
extent that the Underwriters exercise such option, each Underwriter will
become obligated, subject to certain conditions, to purchase its pro rata
portion of such additional shares based on such Underwriter's percentage
underwriting commitment as indicated in the preceding table.
 
                                      50
<PAGE>
 
  The Company and the Selling Shareholders have agreed to indemnify the
Underwriters against certain civil liabilities, including liabilities under
the Securities Act, or to contribute to payments that the Underwriters may be
required to make in respect thereof.
 
  The Company and the Selling Shareholders each have agreed subject to certain
exceptions, not to: (i) offer, pledge, sell, contract to sell, sell any option
or contract to purchase, purchase any option or contract to sell, grant any
option, right or warrant to purchase or otherwise transfer or dispose of,
directly or indirectly, any shares of Common Stock or any securities
convertible into or exercisable or exchangeable for Common Stock; or (ii)
enter into any swap or other arrangement that transfers all or a portion of
the economic consequences associated with the ownership of any Common Stock
(regardless of whether any of the transactions described in clause (i) or (ii)
is to be settled by the delivery of Common Stock, or such other securities, in
cash or otherwise) during the Lock-Up Period without the prior written consent
of DLJ. In addition, the Company has also agreed not to file any registration
statement during the Lock-Up Period with respect to, and each of the Selling
Shareholders has agreed not to make any demand for, or exercise any right with
respect to, the registration of any shares of Common Stock or any securities
convertible into or exercisable or exchangeable for Common Stock without DLJ's
prior written consent.
 
  The foregoing arrangements do not extend to any shares issuable upon
exercise of options granted under the Stock Incentive Plan. As of October 15,
1997, options to acquire 61,850 shares were currently exercisable and options
to acquire an additional 265,202 shares will become exercisable during the
Lock-Up Period.
 
  Other than in the United States, no action has been taken by the Company,
the Selling Shareholders or the Underwriters that would permit a public
offering of the shares of Common Stock offered hereby in any jurisdiction
where action for that purpose is required. The shares of Common Stock offered
hereby may not be offered or sold, directly or indirectly, nor may this
Prospectus or any other offering material or advertisements in connection with
the offer and sale of any such shares of Common Stock be distributed or
published in any jurisdiction, except under circumstances that will result in
compliance with the applicable rules and regulations of such jurisdiction.
Persons into whose possession this Prospectus comes are advised to inform
themselves about and to observe any restrictions relating to the offering of
the Common Stock and the distribution of this Prospectus. This Prospectus does
not constitute an offer to sell or a solicitation of an offer to buy any
shares of Common Stock offered hereby in any jurisdiction in which such an
offer or a solicitation is unlawful.
 
  The Underwriters and dealers may engage in passive market making
transactions in the Common Stock in accordance with Rule 103 of Regulation M
promulgated by the Commission. In general, a passive market maker may not bid
for or purchase shares of Common Stock at a price that exceeds the highest
independent bid. In addition, the net daily purchases made by any passive
market maker generally may not exceed 30% of its average daily trading volume
in the Common Stock during a specified two-month prior period, or 200 shares,
whichever is greater. A passive market maker must identify passive market
making bids as such on the Nasdaq electronic inter-dealer reporting system.
Passive market making may stabilize or maintain the market price of the Common
Stock above independent market levels. Underwriters and dealers are not
required to engage in passive market making and may end passive market making
activities at any time.
 
  In connection with this offering, the Underwriters may engage in
transactions that stabilize, maintain or otherwise affect the price of the
Common Stock. Specifically, the Underwriters may over-allot this offering,
creating a syndicate short position. In addition, the Underwriters may bid for
and purchase shares of Common Stock in the open market to cover syndicate
short positions or to stabilize the price of the Common Stock. These
activities may stabilize or maintain the market price of the Common Stock
above independent market levels. The Underwriters are not required to engage
in these activities and may end any of these activities at any time.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors and Shareholders of Mastech Corporation:
 
  We have audited the accompanying consolidated balance sheets of Mastech
Corporation (a Pennsylvania corporation) and subsidiaries as of December 31,
1995 and 1996, and the related consolidated statements of income,
shareholders' equity and cash flows for each of the three years in the period
ended December 31, 1996, and the consolidated statements of income and cash
flow for the nine months ended September 30, 1996. These Financial Statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these Financial Statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to
obtain reasonable assurance about whether the Financial Statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the Financial Statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the Financial Statements referred to above present fairly,
in all material respects, the financial position of Mastech Corporation and
subsidiaries as of December 31, 1995 and 1996, and the results of their
operations and their cash flows for each of the three years in the period
ended December 31, 1996 and the nine months ended September 30, 1996, in
conformity with generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
         (ALL INFORMATION RELATED TO SEPTEMBER 30, 1997 IS UNAUDITED)
 
1.OPERATIONS:
 
  In conjunction with the closing of its initial public offering on December
16, 1996, Mastech Systems Corporation, the entity through which the business
of the Company had been conducted since its inception in July 1986, became an
indirect, wholly owned subsidiary of Mastech Corporation ("Mastech" or the
"Company"), which is a newly formed Pennsylvania corporation.
 
  Mastech is a worldwide provider of information technology ("IT") services to
large and medium-sized organizations. Mastech provides its clients with a
single source for a broad range of applications solutions and services,
including client/server design and development, conversion/migration services,
Year 2000 services, Enterprise Resource Planning ("ERP") package
implementation services, Internet/intranet services and applications
maintenance outsourcing. These services are provided in a variety of computing
environments and use leading technologies, including client/server
architectures, object-oriented programming languages and tools, distributed
database management systems and the latest networking and communications
technologies. To enhance its services, Mastech has formed business alliances
with leading software companies such as Baan, Oracle and PeopleSoft. In
addition, the Company has developed its own proprietary methodologies and
tools, under the name SmartAPPS, that enhance the productivity of the
Company's Year 2000 and other services.
 
  Mascot Systems Pvt, Ltd. ("Mascot"), a wholly owned foreign subsidiary, was
acquired upon the closing of the Company's initial public offering. Mascot is
currently operating one and constructing two other offshore software
development centers in the cities of Bangalore, Pune and Madras, India,
respectively. Mascot's current operations serve as Mastech's single source for
offshore software development. Also, effective December 16, 1996, SWAT Systems
Corporation, a Pennsylvania corporation ("SWAT"), was merged with and into
Mastech resulting in SWAT's wholly owned subsidiary, Scott Systems Pvt, Ltd.
("Scott"), an India-based corporation, becoming a wholly owned subsidiary of
Mastech. Scott provides IT professional recruiting and training services. As
of December 31, 1996, all of Mascot, SWAT and Scott's revenues were derived
from services provided to Mastech. These transactions are described in Note
11.
 
  The Risk Factors on pages 6, 7, 8 and 11 of the Prospectus entitled
"Recruitment and Retention of IT Professionals," "Government Regulation of
Immigration," "Exposure to Regulatory and General Economic Conditions in
India," "Concentration of Revenue; Risk of Termination," and "Potential
Decrease in Demand for Year 2000 Services" are incorporated herein by
reference.
 
2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  The accompanying Consolidated Financial Statements reflect the application
of the following significant accounting policies:
 
 Principles of Consolidation
 
  The Consolidated Financial Statements include the accounts of the Company
and its wholly owned subsidiaries. All material intercompany transactions and
balances have been eliminated in consolidation.
 
 Accounts Receivable
 
  The Company extends credit to clients based upon management's assessment of
their creditworthiness. Substantially all of the Company's revenues (and the
resulting accounts receivable) are from large companies,
 
                                      F-7

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

major systems integrators and governmental agencies. The allowance for
uncollectible accounts was approximately $500,000, $675,000 and $1,120,000 as
of December 31, 1995 and 1996 and September 30, 1997, respectively.
 
 Revenue Recognition
 
  The Company recognizes revenue on time-and-materials contracts as the
services are performed for clients. Revenues on fixed-price contracts are
recognized using the percentage of completion method. Percentage of completion
is determined by relating the actual cost of work performed to date to the
estimated total cost for each contract. If the estimate indicates a loss on a
particular contract, a provision is made for the entire estimated loss without
reference to the percentage of completion.
 
 Depreciation
 
  The Company provides for depreciation using the straight-line method in
amounts which allocate the costs of equipment over their estimated useful
lives of five to seven years, and leasehold improvements over the shorter of
the life of the improvement or of the underlying lease term.
 
 Currency Translation Adjustment
 
  The financial statements of foreign subsidiaries are translated using the
exchange rate in effect at year-end for balance sheet accounts and the average
exchange rate in effect during the year for revenue and expense accounts.
Translation gains and losses are excluded from the consolidated income
statements and are instead reported as the currency translation adjustment
component of shareholders' equity.
 
  The functional currency of international offices and foreign subsidiaries is
the currency of the country in which the office or subsidiary is located.
Revenues of the Company are billed in the currency of the country in which the
customer is located. Translation gains and losses arising from differences
between the functional and billing currencies are recognized in the
consolidated income statements.
 
 Income Taxes
 
  Prior to its initial public offering, the Company elected to be taxed under
Subchapter S of the Internal Revenue Code of 1986, as amended ("S
corporation") for income tax purposes. Accordingly, the income of the Company
was reported on the individual income tax returns of its shareholders.
Therefore, the financial statements do not include a provision for income
taxes related to income prior to the closing of the public offering.
 
  The Company's S-corporation status terminated in connection with the
Company's initial public offering, thereby subjecting the Company's income to
federal and state income taxes at the corporate level. Due to temporary
differences in recognition of revenues and expenses, income for financial
reporting purposes has exceeded income for income tax purposes. Accordingly,
the application of the provisions of SFAS No. 109, "Accounting for Income
Taxes" resulted in the recognition of deferred tax liabilities (and a
corresponding one-time charge to expense) of $3.9 million as of the date the S
corporation was terminated. The majority of this tax provision will be paid
over the next four years.
 
  In the recent past, the government of India has provided incentives, in the
form of tax holidays, to encourage foreign investment. No tax holidays have
been granted to the Company as of September 30, 1997.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

 Use of Estimates in the Preparation of Financial Statements
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Through April 30, 1996, the Company provided for group medical costs through
self-insurance programs. The amounts charged to expense for group medical
claims were approximately $1,195,000, $2,005,000 and $669,000 for the years
ended December 31, 1994, 1995 and 1996, respectively. Estimated claims
incurred but not reported were $500,000, $370,000 and $0 as of December 31,
1995 and 1996, and September 30, 1997, respectively, and are included in other
accrued liabilities in the accompanying consolidated balance sheets. As of
April 30, 1996, the Company had stop/loss insurance coverage related to these
programs. Effective May 1, 1996, the Company maintains coverage through a
fully insured premium-based plan.
 
 Financial Instruments
 
  The fair values and carrying amounts of the Company's financial instruments,
primarily accounts receivable and payable, are approximately equivalent. The
financial instruments are classified as current and will be liquidated within
the next operating cycle.
 
 Pro Forma Information (Unaudited):
 
  The pro forma adjustments for income taxes included in the accompanying
consolidated income statements are based upon the statutory rates in effect
for C corporations during the periods presented.
 
3.INCOME TAXES
 
  The Company's S-corporation status terminated in connection with the
Company's initial public offering, thereby subjecting the Company's income to
federal and state income taxes at the corporate level. The Company accounts
for income taxes in accordance with the provisions of SFAS No. 109. Except for
the effect of the reversal of net deductible temporary differences, the
Company is not aware of any significant differences between book and taxable
income in future years.
 
  Prior to the initial public offering, the Company elected Subchapter S-
corporation status for income tax purposes. Accordingly, the income of the
Company was reported on the individual income tax returns of its shareholders.
The financial statements, therefore, do not include a provision for income
taxes prior to the closing of the public offering.
 
  The reconciliation of income taxes computed using the statutory U.S. income
tax rate and the provision for income taxes follows:

4.REVOLVING CREDIT FACILITY:
 
  The Company had available borrowings under a revolving credit facility with
a bank. Borrowings under this arrangement were unsecured, were limited to
$15.0 million, bear interest at LIBOR, as defined (7.07 % and 7.50% at
December 31, 1996 and 1995, respectively), plus 1.0% or the prime rate (8.25%
and 8.50% at December 31, 1996 and 1995, respectively) and were payable upon
demand. There were no borrowings outstanding under this arrangement as of
December 31, 1996 and 1995. Average outstanding borrowings under this
arrangement were $535,000 and $1.4 million for the nine months ended September
30, 1997 and the year ended December 31, 1996, respectively. There were no
borrowings under this arrangement during the year ended December 31, 1995.
 
  Effective May 30, 1997, the Company replaced the above mentioned revolving
credit facility with a new revolving credit facility. Borrowings under the new
credit facility are unsecured, are limited to $25.0 million, bear interest at
LIBOR, as defined (6.70% at September 30, 1997), plus 1.0% or the prime rate
(8.5% at September 30, 1997) and are payable upon demand. There were no

these facilities are secured by deposits of the controlling shareholders of
the Company. Of the $2.1 million and $2.2 million borrowed and outstanding
under these agreements at December 31, 1996 and September 30, 1997,
respectively, the following interest rates apply:

  These borrowings will be repaid by the Company prior to December 31, 1997.
 
5.RELATED PARTY TRANSACTIONS:
 
  The controlling shareholders leased residential properties to the Company
under lease agreements which were terminated during 1996. Payments in
accordance with these arrangements were approximately $36,000, $36,000 and
$9,000 for the years ended December 31, 1994, 1995 and 1996, respectively.
 
  The Company has loans outstanding from the Company's controlling
shareholders of $0, $16,000 and $16,000 as of September 30, 1997, December 31,
1996 and 1995, respectively. These loans are included in accounts payable in
the consolidated balance sheets.
 
  As an S corporation, the net income of the Company was attributed, for
federal (and some state) income tax purposes, directly to the Company's
shareholders rather than to the Company. During 1995, 1996 and the nine months
ended 1997, the Company had from time to time paid the corresponding income
taxes due on these amounts on behalf of the controlling shareholders in the
form of interest-free advances which were later repaid. The highest aggregate
amounts of advances outstanding to one of the controlling shareholders and his
Qualified Subchapter S Trust during 1995, 1996 and the nine months ended
September 30, 1997 were approximately $117,000, $1,682,000 and $86,000,
respectively. The highest aggregate amounts of advances outstanding to the
other controlling shareholder during 1995, 1996 and the nine months ended
September 30, 1997 were approximately $117,000, $1,682,000 and $86,000,
respectively.
 
  Mascot Systems leases from the controlling shareholders the office space for
the offshore software development facilities in Bangalore, India. The
acquisition of the real estate and the construction of this office building
(but not the buildout of the office space) was financed entirely by the
controlling shareholders out of personal funds. Specifically, Mascot Systems
leases approximately 4,200 square feet of office space on one floor of an
office building located in Bangalore which floor is owned by the controlling
shareholders. The lease has a one-year term expiring in March 1998, and the
rent is approximately $7,000 per year. Mascot Systems also leases a 30,000-
square-foot office building located in Bangalore from the controlling
shareholders. This lease has a five-year term expiring in October 2001, and
the annual rent is approximately $110,000 per year. The offshore software
development facilities located in Pune and Madras, India are scheduled to be
operational sometime during the first quarter of 1998. Mascot Systems expects
to enter into two additional leases with the controlling shareholders for
these facilities. The facility in Pune is a 35,000-square-foot office
building, and the facility in Madras is a 65,000-square-foot office building.

  Scott Systems leases, for its training facilities, approximately 2,100
square feet of office space on one floor of an office building located in
Mumbai (Bombay, India). The leased space is divided into five separately owned
suites owned individually by the controlling shareholders. The leases have a
one-year term expiring in April 1998, and the aggregate rent is $20,000 per
year. Scott Systems also leases further office space of approximately 900
square feet on another floor in the same office building which is owned by the
controlling shareholders. The lease has a one-year term expiring in October
1998, and the rent is $6,000 per year. Scott Systems also leases a portion of
the Pune facility from the controlling shareholders. This lease covers 7,500
square feet and has a three year term expiring in September 2000. The rent is
$26,000 per year. See also Note 11.
 
  The Company believes that the terms of the leases described above are no
less favorable to the Company than could be obtained from unrelated third
parties.
 
6.COMMITMENTS:
 
  The Company rents certain office facilities and equipment under
noncancelable operating leases which provide for the following future minimum

  Rental expense was approximately $179,000, $500,000, $778,000 and $822,000
for the years ended December 31, 1994, 1995 and 1996 and the nine months ended
September 30, 1997, respectively.
 
  The Company has employment agreements with its controlling shareholders and
certain of its executive officers which provide generally for specified
minimum salaries and bonuses based upon the Company's performance.
 
7.EMPLOYEE BENEFIT PLANS:
 
  The Company adopted a 401(k) benefit plan effective January 1, 1995.
Eligible employees, as defined in the plan, may contribute up to 15% of
eligible compensation, as defined. The Company does not contribute to this
plan.
 
8.NON-RECURRING CHARGES:
 
  In October 1996, the Company entered into an agreement with an executive
pursuant to which the Company agreed to pay this individual, as compensation
for past services, an amount equal to the value of 109,200 shares of Common
Stock at the initial public offering price of $15 per share. One-half of this
payment was made in cash, at the election of the executive, on December 16,
1996. The remaining half of this obligation was satisfied on December 16, 1996
via the issuance of 54,600 shares of restricted Common Stock, as described in
Note 9. The Company has reflected the cash payment along with the applicable
tax withholdings as a non-recurring charge in the accompanying consolidated
statements of income for the year ended December 31, 1996.
 
  In the nine months ended September 30, 1997, the Company has reflected the
amortization of deferred compensation of this same executive as a non-
recurring charge in the accompanying consolidated statements of income.
 
9.STOCK-BASED COMPENSATION AND RESTRICTED STOCK AWARD:
 
  Effective December 16, 1996, the Company adopted the 1996 Stock Incentive
Plan (the "Plan") for directors, executive management and key personnel. The
Plan provides for the issuance of up to 2,160,000 stock-

based incentive awards at the market value of the stock at the date of grant.
The Company accounts for the Plan under Accounting Principles Board Opinion
No. 25, "Accounting for Stock Issued to Employees." Had compensation costs for
the Plan been determined consistent with Statement of Financial Accounting
Standards No. 123, "Accounting for Stock-Based Compensation" (SFAS No. 123),
pro forma net income for the year ended December 31, 1996 would have been
reduced by $12,000 and there would have been no impact on pro forma net income
per common share for the same period.
 
  During 1996 and the nine months ended September 30, 1997, options covering a
total of 845,550 and 392,500 shares, respectively, of Common Stock were
granted under the Plan. The right to purchase these options expires 10 years
from the date of grant or earlier if an option holder ceases to be employed by
the Company for any reason. A summary of stock option activity follows:

  Effective December 16, 1996, the Company entered into an employment
agreement with an executive that included the granting of 54,600 shares of
restricted common stock. During the restricted period (from December 16, 1996
to June 30, 1998), the restricted stock vests ratably and daily. The agreement
provides for partial awards and forfeitures under various circumstances. At
December 31, 1996 and September 30, 1997, the Company's consolidated balance
sheet reflects deferred compensation of $776,000 and $387,000, respectively,
related to this award, as an offset to shareholders' equity. Compensation
expense of $43,000 and $389,000 related to the vesting of restricted shares
during 1996 and the nine months ended September 30, 1997, respectively, has
been recorded in the Company's consolidated income statement.
 
10.PRO FORMA INCOME PER COMMON SHARE AND INCOME PER SHARE:
 
  Pro forma net income and net income per common share is calculated by
dividing pro forma net income and net income, respectively, by the weighted
average number of common shares plus incremental common stock equivalent
shares (shares issuable upon exercise of stock options). Incremental common
stock equivalent shares are calculated for each measurement period based on
the treasury stock method which uses the monthly average market price per
share.
 
  The weighted average common shares and common share equivalents were as
follows:
 
<TABLE>
<CAPTION>
     DECEMBER 31, 1994   DECEMBER 31, 1995 DECEMBER 31, 1996 SEPTEMBER 30, 1997

</TABLE>
 
  The 1996 weighted average shares outstanding as calculated above also
includes 393,462 common shares, which represents the number of shares, when
multiplied by the initial public offering price, would have been sufficient to
replace the capital in excess of earnings withdrawn as dividends during the
period.
 
  In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128, "Earnings per Share" (SFAS No.
128), which establishes new standards for computing and presenting earnings
per share and applies to entities with publicly and non-publicly held common
stock. SFAS No. 128 is effective for financial statements issued for periods
ending after December 15, 1997, including interim periods. Earlier application
is not permitted. SFAS No. 128 requires restatement of all prior period
earnings per share data presented. The Company has determined that the
adoption of SFAS No. 128 will not change reported earnings per share for any
period.
 
11.BUSINESS ACQUISITIONS:
 
  Mascot Systems, prior to becoming a subsidiary of the Company, was owned by
Mastech's controlling shareholders. The Company has in the past engaged Mascot
Systems as a subcontractor to perform offshore software development projects.
On December 16, 1996, the Company purchased the shares of Mascot Systems held
by the controlling shareholders for $170,000. This price was based upon an
independent valuation of that interest and paid from the Company's working
capital. The Company has also purchased the minority shares of Mascot Systems,
which were held by relatives of the controlling shareholders, for $20,000,
based upon an independent valuation. This transaction has been reflected as a
disproportionate dividend in the accompanying statements of shareholders'
equity.
 
  Scott Systems, prior to becoming a subsidiary of the Company, was indirectly
controlled by Mastech's controlling shareholders through SWAT Systems
Corporation. The Company has in the past engaged Scott Systems to recruit and
train IT professionals in India. On December 16, 1996, SWAT was merged with
and into Mastech and Scott Systems thereby became a subsidiary of the Company.
The controlling shareholders received nominal consideration in this
transaction. The Company also purchased the minority shares of Scott Systems,
some of which are held by relatives of the controlling shareholders, for
$26,000.

  The accompanying Consolidated Financial Statements present the financial
position, results of operations and cash flows of the Company and the
aforementioned entities as if they had been combined from inception in a
manner similar to a pooling of interests.
 
12.S-CORPORATION DIVIDEND:
 
  Since it was founded in 1986, the Company had elected S-corporation status
for income tax purposes. As a result, substantially all of the Company's net
income was attributed, for income tax purposes, directly to the Company's
shareholders rather than to the Company. The Company's S-corporation status
terminated in connection with its public offering of common stock, and the
Company will make a final distribution to its former S-corporation
shareholders of undistributed S-corporation earnings, as explained below.
 
  On December 16, 1996, the Company's Board of Directors declared an S-
corporation dividend to former S-corporation shareholders in an aggregate
amount representing the estimated amount of all undistributed earnings of the
Company taxed or taxable to its shareholders through December 16, 1996 (the
"S-corporation Dividend"). The S-corporation Dividend is recorded in the
accompanying consolidated balance sheets at December 31, 1996 in the amount of
$6.5 million. The S-corporation Dividend was paid in the amount of $6.3
million in 1997 with the difference being recognized as an increase in
additional paid-in capital as shown in the accompanying consolidated
