a solution to the Year 2000 problem. For financial reporting purposes, the

                                    OVERVIEW
 
THE MERGER
 
  ZMAX Corporation, a Nevada corporation ("Old ZMAX"), proposes to merge with
and into New ZMAX Corporation, a Delaware corporation ("New ZMAX"), pursuant to
an Agreement and Plan of Merger dated as of June 10, 1997 between Old ZMAX and
New ZMAX (the "Merger Agreement"). See "The Merger." At the time the Merger
becomes effective, each outstanding share of Common Stock, $0.001 par value, of
Old ZMAX ("Old ZMAX Common Stock") will be converted into the right to receive,
and will be exchangeable for one share of Common Stock, $0.001 par value, of
New ZMAX ("New ZMAX Common Stock"). New ZMAX intends to apply for quotation of
the New ZMAX Common Stock on the Nasdaq SmallCap Market. Shares of New ZMAX
Common Stock issued in the Merger will be freely transferable without
restriction under the Securities Act of 1933, as amended, except for shares of
New ZMAX Common Stock beneficially owned by affiliates of New ZMAX or subject
to contractual restriction. See "Shares Eligible for Future Sale."
 
THE EXCHANGE OFFER
 
  Old ZMAX hereby offers, upon the terms and conditions set forth in this Proxy
Statement/Prospectus and the accompanying Letter of Transmittal (the "Letter of
Transmittal," which together with this Proxy Statement/Prospectus, constitutes
the "Exchange Offer"), to each holder of Old ZMAX's 8% Convertible Exchangeable
Subordinated Debentures due 1999 (the "Debentures") the opportunity to exchange
all, but not less than all, Debentures held by such holder for (i) 220 shares
of Old ZMAX Common Stock and (ii) a Warrant to purchase 220 shares of Old ZMAX
Common Stock (the "Warrant Shares"), for each $1,000 principal amount of
Debentures. The Letter of Transmittal also invites the exchanging Debenture
holder to immediately exercise the Warrants received in the Exchange Offer. The
exchange of at least 90% of the Debentures for Old ZMAX Common Stock and the
exercise of Warrants for at least 80% of the Warrant Shares are conditions to
the consummation of the Merger. See "The Exchange Offer" and "The Merger--The
Merger Agreement--Conditions to the Merger."
 
THE MEETING
 
  At the Old ZMAX 1997 Annual Meeting of Stockholders (the "Meeting"), the
stockholders of Old ZMAX will be asked to (i) elect directors to serve until
the next annual meeting, (ii) approve the ZMAX Corporation
 
                                       4
<PAGE>
 
1997 Stock Incentive Plan (the "Incentive Plan"), and (iii) consider and vote
upon the proposal to approve and adopt the Merger Agreement. The Meeting is
scheduled to be held at 11:00 A.M., local time, on September  , 1997, at
[location to be determined]. The Board of Directors of Old ZMAX (the "Old ZMAX
Board") has fixed the close of business on August  , 1997 as the record date
(the "Record Date") for the determination of holders of Old ZMAX Common Stock
entitled to notice of and to vote at the Meeting. Only holders of record of Old
ZMAX Common Stock at the close of business on the Record Date will be entitled
to notice of and to vote at the Meeting. See "The Meeting."
 
  The Old ZMAX Board unanimously approved the Merger Agreement and recommends
that Old ZMAX stockholders vote "FOR" approval and adoption of the Merger
Agreement. See "The Merger--Recommendations of the Board and Principal Reasons
for the Merger and the Exchange Offer" and "The Merger--Interests of Certain
Persons." The Old ZMAX Board also recommends that Old ZMAX stockholders vote
"FOR" the nominees for election as directors and "FOR" the approval of the
Incentive Plan.
 
THE PARTIES
 
  Old ZMAX focuses on acquiring, building and operating companies in the
information technology industry. In September 1996, Old ZMAX agreed to acquire
all of the shares in Century Services, Inc., a Maryland corporation ("CSI").
CSI offers re-engineering and information processing services to users of
large-scale computer systems in North America and Europe. CSI specializes in
assisting business organizations and government agencies with what has become
popularly known as the "Year 2000 problem." Over the next several years, CSI
expects to devote substantial resources to assisting its clients in preparing
for and implementing the conversion of their computer systems to allow those
clients to continue operations without interruption in the 21st Century. See
"The Company" and "Business."
 
  New ZMAX is a newly formed, wholly owned subsidiary of Old ZMAX formed solely
for the purpose of effecting the Merger. New ZMAX has not previously conducted
any business but will assume and carry on Old ZMAX's business without change
after the Effective Time of the Merger.
 
  Following the Merger, New ZMAX is expected to change its name to "ZMAX
Corporation." CSI will continue to conduct its business as a wholly owned
subsidiary of New ZMAX.
 
                                   THE MERGER
 
  At the time the Merger becomes effective, Old ZMAX will be merged with and
into New ZMAX and Old ZMAX will cease to exist as a corporation. New ZMAX will
be the surviving corporation in the Merger, and CSI will thereby become a
wholly owned subsidiary of New ZMAX. All issued and outstanding shares of Old
ZMAX Common Stock will represent the right to receive and will be exchangeable
for one share of New ZMAX Common Stock in the Merger. See "The Merger."
 
REQUIRED VOTE
 
  Approval of the Merger requires the affirmative vote of the holders of a
majority of the outstanding shares of Old ZMAX Common Stock entitled to vote.
 
EFFECTIVE TIME
 
  After all the conditions set forth in the Merger Agreement have been
satisfied or waived, the Merger will become effective at such time as a
Certificate of Merger required under the Nevada Revised Statutes (the "Nevada
Law") and the Delaware General Corporation Law (the "Delaware Law") is filed
with the Secretaries of State of the States of Nevada and Delaware (the
"Effective Time"). Such filing will be made simultaneously with or as soon as
practicable after the closing of the Merger.
 
 
                                       5
<PAGE>
 
EXCHANGE OF STOCK CERTIFICATES
 
  From and after the Effective Time, each share of Old ZMAX Common Stock will
be automatically converted into the right to receive one share of New ZMAX
Common Stock. As soon as practicable after the Effective Time, New ZMAX will
send transmittal instructions to each former Old ZMAX stockholder describing
the procedure for surrendering Old ZMAX stock certificates for New ZMAX stock
certificates.
 
RECOMMENDATIONS OF THE BOARD AND REASONS FOR THE MERGER
 
  The Old ZMAX Board unanimously approved the Merger Agreement and recommends
that the Old ZMAX stockholders vote "FOR" approval and adoption of the Merger
Agreement. The recommendation of the Old ZMAX Board regarding the Merger
Agreement is based upon the belief of the Old ZMAX directors that the terms of
the Merger Agreement are fair from a financial point of view to the
stockholders of Old ZMAX. For a discussion of Old ZMAX's reasons for the
Merger, see "The Merger--Recommendations of the Board and Principal Reasons for
the Merger and the Exchange Offer."
 
INTERESTS OF CERTAIN PERSONS
 
  None of Old ZMAX's directors, director nominees or executive officers have
any material interest in the Merger other than their respective pro rata
interest as a result of their beneficial ownership of Old ZMAX Common Stock. No
option or employee benefit will vest or accelerate as a result of the Merger.
None of Old ZMAX's directors, director nominees or executive officers, directly
or indirectly, hold any Debentures. As of the Record Date, Old ZMAX's current
directors, executive officers and their affiliates owned [1,867,942] shares of
Old ZMAX Common Stock entitled to vote at the Meeting (representing [19.8%] of
the outstanding Old ZMAX Common Stock), and each of such individuals have
indicated their intention to cause these shares to be voted in favor of the
Merger Agreement.
 
CONDITIONS TO THE MERGER
 
  The obligations of New ZMAX and Old ZMAX to consummate the Merger are subject
to the satisfaction or waiver of certain conditions, including (i) the approval
of the Merger Agreement by the Old ZMAX stockholders, (ii) the exchange of at
least 90% of the Debentures in the Exchange Offer and (iii) the exercise of
Warrants for at least 80% of the Warrant Shares. See "The Merger--The Merger
Agreement--Conditions to the Merger."
 
RIGHTS TO TERMINATE AND AMENDMENTS
 
  The Merger Agreement may be terminated prior to the closing of the
transactions contemplated thereby under certain circumstances. Subject to
compliance with applicable law, the Merger Agreement may be amended at any time
prior to the Effective Time by a written agreement executed by New ZMAX and Old
ZMAX.
 
COMPARISON OF RIGHTS UNDER APPLICABLE LAW
 
  The rights of stockholders of Old ZMAX are currently governed by the Nevada
Law, the Old ZMAX Articles of Incorporation and the Old ZMAX Bylaws. After the
Merger, Old ZMAX stockholders will become stockholders of New ZMAX and from and
after the Effective Time their rights as stockholders of New ZMAX will be
governed by the Delaware Law, the Amended and Restated New ZMAX Certificate of
Incorporation and the Amended and Restated New ZMAX Bylaws that will be adopted
as part of the Merger. See "Comparison of Stockholder Rights."
 
CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER
 
  It is expected that the Merger will constitute a reorganization for U.S.
federal income tax purposes and, accordingly, that no gain or loss will be
recognized by holders of Old ZMAX Common Stock upon the exchange
of Old ZMAX Common Stock for shares of New ZMAX Common Stock (except with
respect to any cash received upon the exercise of dissenters' rights) and the
exchange of Old ZMAX Warrants (received pursuant to
 
                                       6
<PAGE>
 
the Exchange) for New ZMAX Warrants. See "The Merger--U.S. Federal Income Tax

the Merger to such stockholder.

                                  RISK FACTORS
 
  In considering the transactions described herein, investors should consider

expended substantial time and financial resources in developing a new and
innovative solution for the Year 2000 problem that has not yet been utilized in
any large scale conversion project; (iii) uncertainty regarding New ZMAX's and
CSI's future additional capital requirements; (iv) significant competition in
the Year 2000 industry; (v) New ZMAX's and CSI's dependence on its ability to
hire and retain key personnel; (vi) the uncertainty with respect to the payment
of dividends on the New ZMAX Common Stock; (vii) the potential volatility of
the stock price as demonstrated by the quoted market price compared to prices
in the CSI recapitalization transactions, and (viii) the limited information on
the Company and its security holders and the limitations on the ability to
enforce securities laws against non-U.S. persons. See "Risk Factors."

(A) Pro Forma As Adjusted assumes (i) that the Debentures are fully exchanged
    in the Exchange Offer for 1,210,000 shares of Old ZMAX Common Stock and
    Warrants to purchase an equal number of shares, (ii) the full exercise of
    the Warrants into 1,210,000 shares of Old ZMAX Common Stock at $7.00 per
    share and (iii) that the fair market value of the Company's Common Stock on
    the date of the Exchange Offer is $14.375 (the closing price on June 18,
    1997 as quoted on the OTC Bulletin Board). Pro Forma As Adjusted also
    includes issuances of Old ZMAX Common Stock since March 31, 1997 (see
    "Management's Discussion and Analysis of Financial Condition and Results of
    Operations--Recent Developments"), including (i) 1,600,000 shares issued in
    April 1997 upon the conversion of the Company's convertible notes,
    (ii) 670,000 shares issued in April 1997 in connection with the CSI
    transaction, (iii) 234,365 shares issued in April 1997 in connection with
    the Company's purchase of Fiserv's interest in the Fiserv Century Services
    Joint Venture, (iv) 32,077 shares issued in May 1997 as satisfaction for a
    promissory note, (v) 150,000 shares issuable in connection with the
    Company's acquisition of the COCACT Software, and (vi) 60,000 shares
    issuable to a consultant for services rendered. For shares not issued as of
    June 18, 1997, the closing price of $14.375 on June 18, 1997 is assumed to
    be the fair market value of the Company's Common Stock on the date of
    issuance. Pro Forma As Adjusted also assumes that the Merger has been

                                 RISK FACTORS
 
  Investment in the Company involves a high degree of risk. Investors should
consider carefully the following factors, in addition to the other information
contained in this Proxy Statement/Prospectus, in evaluating the transactions
described herein. This Proxy Statement/Prospectus contains, in addition to
historical information, forward-looking statements that involve risks and
uncertainties. The Company's actual results could differ materially. Factors
that could cause or contribute to such difference include, but are not limited
to, those discussed below, as well as those discussed elsewhere in this Proxy
Statement/Prospectus.
 
  Lack of Experience in Millennium Services. The Company has limited
experience in providing its Year 2000 or "millennium" services. Although the
Company has successfully completed a number of assessment projects and small-
scale (pilot) conversion projects, the Company has not completed a large-scale
millennium conversion project either alone or together with a strategic
partner. Pilot projects performed by the Company to date have generally
consisted of performing test conversions on a small portion of a client's
mainframe computer system. There can be no assurance that the Company will be
successful in completing large-scale conversions, that the Company will not
experience delays or failures in providing its millennium services, or that
its millennium services will be effective. In the pilot projects completed to
date, the amount of failures, errors and bugs detected, and the cost of
correcting them, have not been significant and have not had a material adverse
affect on the Company's business, operating results or financial condition.
However, the failure of the Company's Year 2000 methodology to function
properly in the future or the existence of significant errors or bugs
following completion of future millennium conversions could necessitate
significant expenditures by the Company to remedy the problem. The
consequences of failures, errors or bugs could materially and adversely affect
the Company's business, operating results and financial condition.
 
  Recent Losses and Need for Additional Working Capital. The Company incurred
losses of $11.5 million and $2.1 million for the year ended December 31, 1996
and the three months ended March 31, 1997, respectively. As a result, the
Company had an accumulated deficit of $11.5 million and $13.7 million as of
December 31, 1996 and March 31, 1997, respectively. The Company expects to
require significant amounts of cash to support marketing and other anticipated
activities related to the establishment of its Year 2000 services business.
See "Management's Discussion and Analysis of Financial Conditions and Results
of Operations. " There can be no assurance that the Company will not
experience liquidity problems because of adverse market conditions or other
unfavorable events. Further, because of the various business risks described
elsewhere in this "Risk Factors" discussion, there can be no assurance that
the Company will be profitable. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital
Resources."
 
  No Liquid Market; Possible Volatility of Stock Price. Prior to the
completion of the transactions contemplated by this Proxy
Statement/Prospectus, the U.S. trading market for the Old ZMAX Common Stock
has been limited and characterized by significant price and volume volatility.
Old ZMAX has not been subject to the periodic reporting requirements of the
Exchange Act and accordingly current public information regarding Old ZMAX and
its business has not been widely disseminated by Old ZMAX. As a result of the
foregoing, historical price quotations for the Old ZMAX Common Stock may not
be indicative of the operations, financial conditions or prospects for the
Company. In this regard, the Company issued Common Stock and Common Stock
equivalents in the fall of 1996 at prices less than the quoted market price at
such time. See Notes 7 and 9 of the Financial Statements of ZMAX Corporation
for the year ended December 31, 1996 included elsewhere herein. There can be
no assurance that an active trading market for the New ZMAX Common Stock will
develop or, if such a market does develop, that the market price for the New
ZMAX Common Stock price will not be subject to significant fluctuations in
response to factors such as, among others, variations in the Company's
anticipated or actual results of operations, announcements of new products or
technological innovations by the Company or its competitors, and changes in
earnings estimates by analysts. In addition, the stock market is subject to
price and volume fluctuations that affect the market prices for companies in
general, and small capitalization, emerging growth and technology companies
like the Company in particular, which fluctuations are often unrelated to the
operating performance of such companies. These broad market fluctuations could
adversely affect the market prices of the New ZMAX Common Stock. Investors in
the Company may experience dilution of their investment
 
                                      10
<PAGE>
 
upon certain events, such as the issuance of shares of New ZMAX Common Stock
pursuant to the exercise of outstanding warrants and stock options.
 
  Limited Information on Security Holders; Enforcement of Securities Laws
Against Non-U.S. Persons. The beneficial ownership reporting requirements of
Section 13(d) of the Exchange Act are not applicable to the Company's
stockholders because the Old ZMAX Common Stock is not a registered class of
equity securities under the Exchange Act. The Company believes a substantial
portion of its equity securities are held by non-U.S. persons, including non-
U.S. banks that hold securities on behalf of their customers and are prohibited
by local bank secrecy laws from disclosing information regarding the beneficial
ownership of accounts. Up to an additional 2,420,000 shares of New ZMAX Common
Stock would be issued to non-U.S. persons in connection with the Exchange Offer
and the exercise of the Warrants. As a result of the foregoing, non-U.S.
persons may be able to substantially influence the trading market for the
Common Stock. The Company and its shareholders may have difficulty in effecting
service of process and enforcing civil liabilities arising under U.S.
securities laws against non-U.S. persons.
 
 
  Availability of Technical Personnel. The Company's strategy will require the
addition of skilled technical, marketing and management personnel. The Company
competes with major computer, communications, consulting and software
companies, as well as information service departments of major corporations, in
seeking to attract qualified personnel. This competition is expected to
intensify as demand for millennium services grows. There can be no assurance
that the Company will be able to attract and retain the personnel necessary to
pursue its strategy.
 
  Uncertain and Undeveloped Market for Millennium Services. Millennium services
are expected to represent the significant portion of the Company's business for
the next several years. Although the Company believes that the market for
millennium services will grow significantly as the Year 2000 approaches, there
can be no assurance that this market will develop to the extent anticipated by
the Company, or at all. Significant expenses for sales and marketing may be
required to inform the public of the Year 2000 problem and the need for
millennium services. There can be no assurance that the millennium services
industry will devote the resources necessary to effectively inform the public
of the Year 2000 problem or that potential clients will understand or
acknowledge its significance. In addition, companies affected by the Year 2000
problem may not be willing or able to allocate the resources, financial or
otherwise, to address the problem in a timely manner. Many companies may be
able to resolve the problem using internal staff, by discontinuing the use of
some older programs, or by replacing existing systems with new Year 2000
compliant systems. Therefore, the development of the market for millennium
services is uncertain and unpredictable. If the market for millennium services
fails to grow, or grows more slowly than anticipated, the Company's business,
operating results and financial condition could be materially and adversely
affected.
 
  Competition. The market for millennium services is highly competitive and
will become increasingly competitive as the Year 2000 approaches. The primary
competitive factors in the computer services industry are availability of
equipment and facilities, price, service and whether the provider's personnel
possess the skills and knowledge necessary to solve information processing
problems. A number of companies engaged in millennium services are more
established, benefit from greater name recognition and have substantially
greater financial, technical and marketing resources than the Company.
Moreover, other than technical expertise, there are no significant proprietary
or other barriers to entry in the Year 2000 services market that could keep
competitors from developing similar services or providing competing services to
those offered by the Company. There can be no assurance that the Company will
be able to compete successfully against its competitors or that the competitive
pressures faced by the Company will not affect its financial performance.
 
  Rapid Technological Change. The information technology industry is
characterized by rapidly evolving technology and changing methodologies. The
introduction of software tools embodying new technology and the emergence of
new methodologies could render obsolete existing products and services,
including the Company's. The Company's future success will depend on its
ability to continue to refine and update its proprietary
 
                                       11
<PAGE>
 
methodologies for correcting the Year 2000 problem. There can be no assurance
that one or more of the Company's competitors will not develop a software tool
or methodology that is superior to, or achieves a greater market acceptance
than, the Company's methodology. The development of a superior tool or
methodology by one or more competitors, or any failure by the Company to
successfully respond to such development, could materially and adversely affect
the Company's business, operating results and financial condition.
 
  Need to Develop Additional Products and Services. The Company currently
expects to generate most of its revenue from, and devote most of its resources
to, its Year 2000 services. The Company believes that the demand for its
millennium services will continue to exist for some time after the Year 2000,
however, this demand will diminish significantly over time and will eventually
disappear. Therefore, the Company plans to continue actively pursuing business
opportunities unrelated to the Year 2000 problem in the computer software re-
engineering and consulting market, with a focus on the conversion marketplace,
and to develop products and services to take advantage of those opportunities.
The Company intends to use the relationships developed and experience obtained
while performing complex Year 2000 conversion projects to address other
information systems requirements of its clients. However, there can be no
assurance that the Company will be able to successfully expand its business
beyond the millennium conversion market. The failure to develop additional
computer software and services could materially and adversely affect the
Company's business, operating results and financial condition.
 
  Dependence on Key Executives. The Company is largely dependent on the efforts
of Michael C. Higgins, its President, and Joseph Yeh, its Senior Vice
President--Technology. There can be no assurance that the Company will be able
to retain the services of Mr. Higgins or Mr. Yeh. Although the Company intends
to obtain life insurance on the lives of Mr. Higgins and Mr. Yeh, the loss of
either of them could materially and adversely affect the Company's business,
operating results and financial condition. See "Management and Executive
Compensation."
 
  Limited Protection of Proprietary Information. The Company depends in part on
its proprietary know-how to differentiate its millennium services from that of
its competitors. The Company does not have any patents and relies upon a
combination of trade secret, copyright and trademark laws and contractual
restrictions to establish and protect its proprietary information. The Company
generally enters into non-disclosure and confidentiality agreements with its
employees, consultants and clients. Despite these precautions, it may be
possible for an unauthorized third party to replicate the Company's millennium
service methodology or to obtain and use information that the Company regards
as proprietary. There can be no assurance that the means used by the Company to
protect its proprietary information will be adequate or that the Company's
competitors will not independently develop substantially similar or superior
techniques to resolve the Year 2000 problem.
 
  Risks of Third Party Claims of Infringement. As the number of competitors
providing millennium services increases, overlapping techniques used in such
services will become more likely. There can be no assurance that third parties
will not assert infringement claims against the Company in the future, that
assertion of such claims will not result in litigation, or that the Company
would prevail in such litigation or be able to obtain a license for the use of
any infringed intellectual property from a third party on commercially
reasonable terms. Furthermore, litigation, regardless of its outcome, could
result in substantial cost to the Company and divert management's attention
from the Company's operations. Any infringement claim or litigation against the
Company could materially and adversely affect the Company's business, operating
results and financial condition.
 
  Potential Contract Liability. The Company's millennium services involve key
aspects of its clients' computer systems. Any failure in a client's system
could result in a claim for substantial damages against the Company, regardless
of the Company's responsibility for such failure. The Company attempts to limit
by contract its liability for damages arising from negligent acts, errors,
mistakes or omissions in rendering its professional services. Despite this
precaution, there can be no assurance that the limitations of liability set
forth in its service contracts would be enforceable or would otherwise protect
the Company from liability for damages. The Company maintains general liability
coverage, and is in the process of evaluating coverage options for errors and
omissions and professional liability. However, there can be no assurance that
such coverage will continue to
 
                                       12
<PAGE>
 
be available in sufficient amounts to cover one or more large claims, or that
the insurer will not disclaim coverage as to any future claim. The successful
assertion of one or more large claims against the Company that exceed available
insurance coverage, or changes in the Company's insurance policies, including
premium increases or the imposition of a large deductible or co-insurance
requirements, could materially and adversely affect the Company's business,
operating results and financial condition.
 
  Risk of Low-Priced Stocks. The Company intends to apply for the listing of
the Common Stock on the Nasdaq SmallCap Market effective upon completion of the
transactions contemplated by this Proxy Statement/Prospectus. To qualify for
listing and to continue to be listed on the Nasdaq SmallCap Market, a company
must meet certain financial criteria. Although the Company expects to meet
these criteria upon completion of the Merger, there can be no assurance that
the Company will meet such tests or will continue to do so in the future.
Failure to obtain a listing on the Nasdaq SmallCap Market would reduce market
interest in the New ZMAX Common Stock. Failure to meet such criteria in the
future may result in the delisting of the New ZMAX Common Stock from the Nasdaq
SmallCap Market.
 
  Shares Eligible for Future Sale. Upon completion of the transactions
contemplated by this Proxy Statement/Prospectus, all of the outstanding New
ZMAX Common Stock will generally be freely transferable without restriction
under the Securities Act, except for shares held by affiliates of the Company
or subject to contractual restrictions. The possibility that substantial
amounts of Common Stock may be sold in the public market would likely have a
material adverse effect on prevailing market prices of the Common Stock and
could impair the Company's ability to raise capital through the sale of its
equity securities. See "Shares Eligible for Future Sale."
 
  Management of Growth. The Company expects to experience significant expansion
that will place substantial demands upon its management, systems and resources,
including its sales, project management and consulting personnel, as well as
the Company's research and development, finance and administrative operations.
The Company's ability to manage its future growth, if any, will require the
Company to continually improve its financial and management controls and
reporting systems and procedures, as well as implementing new systems as
necessary and expanding, training and managing its workforce. There can be no
assurance that the Company's controls, systems or procedures will continue to
be adequate to support the Company's operations. The Company's management team
has had limited prior experience managing a public company or a rapidly growing
business. The failure of the Company's management to respond effectively to
changing business conditions could have a material adverse effect upon the
Company's business, operating results and financial condition.
 
                                  THE MEETING
 
PURPOSE OF THE MEETING
 
  Old ZMAX has called its 1997 Annual Meeting of Stockholders (the "Meeting")
to be held at [location to be determined] on September  , 1997, at 11:00 A.M.
local time. At the Meeting, the holders of Old ZMAX Common Stock will be asked
(i) to elect nominees to serve as directors of the Company, (ii) to approve the
Incentive Plan and (iii) to approve and adopt the Merger Agreement and the
transactions contemplated thereby. See "The Merger."
 
DIRECTOR NOMINEES
 
  Pursuant to the Old ZMAX Bylaws, the Board of Directors of Old ZMAX has set
the size of the Board of Directors at six members and has nominated the
following persons to serve as directors of Old ZMAX subject to vote of the Old
ZMAX stockholders at the Meeting:

nominees, see "Management and Executive Compensation--Directors and Director
Nominees" and "Proposal to Elect Directors."
 
                                       13

STOCK INCENTIVE PLAN
 
  The Incentive Plan was adopted by the Old ZMAX Board of Directors and
provides the Company with increased flexibility to grant equity-based
compensation to key employees, officers, directors and consultants of the
Company. For a detailed description of the Incentive Plan, see "Proposal to
Approve ZMAX Corporation 1997 Stock Incentive Plan."
 
RECOMMENDATIONS OF THE BOARD
 
  The Old ZMAX Board recommends a vote "FOR" each of the nominees for the
Board of Directors and "FOR" approval of the Incentive Plan. The Old ZMAX
Board has also unanimously approved the Merger Agreement and the transactions
contemplated thereby and recommends that the Old ZMAX stockholders vote "FOR"
approval and adoption of the Merger Agreement and the transactions
contemplated thereby. See "The Merger--Recommendations of the Board and
Principal Reasons for the Merger and the Exchange Offer." In rendering its
recommendation to the Old ZMAX stockholders, the Old ZMAX Board concluded that
the overall effect of the Merger and the other transactions that will occur in
conjunction with the Merger, including the Exchange Offer and the Warrant
exercise, would result in a significant infusion of equity capital and the
development of a more liquid trading market for New ZMAX Common Stock
following the Merger and the availability of current public information
regarding New ZMAX since, following the Merger, New ZMAX will be subject to
the periodic reporting obligations contained in the Securities Exchange Act of
1934, as amended (the "Exchange Act"). This result should facilitate the
ability of New ZMAX to access the capital markets in the future. The
obligations of New ZMAX and Old ZMAX to consummate the Merger are subject to
the satisfaction or waiver of a number of conditions, including the approval
of the Merger Agreement by the Old ZMAX stockholders, the exchange of at least
90% of the Debentures and the exercise of Warrants for at least 80% of the
Warrant Shares. See "The Merger--The Merger Agreement--Conditions to the
Merger."
 
DATE, TIME AND PLACE; RECORD DATE
 
  The Meeting is scheduled to be held at 11:00 A.M., local time on September
 , 1997, at [location to be determined]. The Old ZMAX Board has fixed the
close of business on August  , 1997 as the record date (the "Record Date") for
the determination of holders of Old ZMAX Common Stock entitled to notice of
and to vote at Meeting. Only holders of record of Old ZMAX Common Stock at the
close of business on the Record Date will be entitled to notice of and to vote
at the Meeting.
QUORUM AND VOTING RIGHTS
 
 
  Under the Nevada Law, directors are elected by plurality vote, and
therefore, the six candidates receiving the highest number of votes of shares
of Old ZMAX Common Stock entitled to be voted will be elected. Votes withheld
from any candidate(s) and abstentions will have no effect on the election of
directors. The approval of the Incentive Plan requires the affirmative vote of
a majority of the shares of Old ZMAX Common Stock present in person or
represented by proxy at the Meeting and entitled to vote on such matters.
Pursuant to the Nevada Law, the affirmative vote of the holders of at least a
majority of shares of Old ZMAX Common Stock outstanding and entitled to vote
as of the Record Date is required to approve and adopt the Merger Agreement
and the transactions contemplated thereby. Abstentions and broker non-votes
will have the effect of a vote against the proposals to approve the Merger
Agreement and the Incentive Plan. A broker non-vote occurs when a nominee of a
beneficial owner of shares of Old ZMAX Common Stock does not have
discretionary authority with respect to a matter and does not receive voting
instructions from such beneficial owner.
 
  At the Record Date, there were 9,450,514 shares of Old ZMAX Common Stock
outstanding. Holders of record of Old ZMAX Common Stock on the Record Date are
entitled to one vote per share at the Meeting. The presence, either in person
or by proxy, of the holders of a majority of the outstanding shares of Old
ZMAX Common Stock outstanding and entitled to vote as of the Record Date at
the Meeting is necessary to constitute a quorum at the Meeting.
 
  The Old ZMAX Board is soliciting proxies so that each holder of Old ZMAX
Common Stock on the Record Date has the opportunity to vote in the election of
directors, to approve the Incentive Plan and to approve and adopt the Merger
Agreement at the Meeting. When a proxy card is returned properly signed and
dated, the shares
 
                                      14
<PAGE>
 
represented thereby will be voted in accordance with the instructions on the
proxy card. If a stockholder does not return a signed proxy card, his or her
shares will not be voted and thus will have the effect of a vote against the
approval of the Incentive Plan and the Merger Agreement. Abstentions will be
counted for purposes of determining the existence of a quorum at the Meeting.
Since approval of the Incentive Plan requires the affirmative vote of a
majority of the shares of Old ZMAX Common Stock present and entitled to vote
at the Meeting and approval of the Merger requires the affirmative vote of a
majority of the issued and outstanding shares of Old ZMAX Common Stock
entitled to vote thereon, abstentions will have the effect of a negative vote
on these proposals. If a stockholder returns a signed proxy card, but does not
indicate how his or her shares are to be voted, the shares of Old ZMAX Common
Stock represented by such proxy card will be voted "FOR" election of the
nominees named herein as directors, "FOR" approval of the Incentive Plan and
"FOR" approval and adoption of the Merger Agreement and the transactions
contemplated thereby. The proxy card also confers discretionary authority on
the individuals appointed by the Old ZMAX Board and named on the proxy card to
vote the shares represented thereby on any matter incidental to the Meeting
that is properly presented for action at the Meeting.
 
  Any Old ZMAX stockholder who executes and returns a proxy card may revoke
such proxy at any time before it is voted by (i) notifying in writing the
Secretary of Old ZMAX at c/o ZMAX Corporation, 20251 Century Boulevard,
Germantown, Maryland 20874, (ii) granting a subsequent proxy or (iii)
appearing in person and voting at the Meeting. Attendance at the Meeting will
not in and of itself constitute revocation of a proxy.

                                  THE COMPANY
 
  The Company was organized as a Nevada corporation on April 24, 1986, under
the name of Pandora, Inc. for the purpose of creating a vehicle to obtain
capital to seek out, investigate and acquire interests in products, properties
and businesses that may have potential for profit. Until May 4, 1992, the
Company transacted no business other than the investigation of various
business opportunities. On May 4, 1992, the Company amended its Articles of
Incorporation to change the name of the Company to Oryx Gold Corporation in
connection with a reorganization in which the Company acquired 100% ownership
of American Oil and Gas Corporation ("American Oil"). American Oil was
organized on November 22, 1991, as a Nevada corporation, and conducted no
business other than the acquisition of an interest in certain unpatented
placer mining claims in Nevada. The Company intended to develop the mining
claims and other acquired interests in the mining and gas industry in a manner
profitable to the Company and, on August 16, 1995, the Company changed its
name to Mediterranean Oil Corporation to more accurately reflect the nature of
its business. The Company did not subsequently pursue this business. American
Oil's corporate status has been suspended by the Secretary of State of Nevada
as of December 1, 1995, and this subsidiary has been abandoned by the Company.
 
  In the summer of 1996, the Company identified Century Services, Inc. ("CSI")
as a new acquisition target and signed a letter of intent to acquire all of
the issued and outstanding stock of CSI on September 20, 1996. In connection
with preparing for the CSI transaction, the Company undertook a reverse share
split to reduce the number of shares of its Common Stock outstanding and
changed its name to ZMAX Corporation. Following this restructuring, on
November 6, 1996, the Company acquired 100% of the issued and outstanding
stock of CSI, and CSI is now a wholly owned subsidiary of the Company. CSI was
a privately held company formed as a Maryland corporation in December 1995 to
perform software re-engineering related to providing a solution to the Year
2000 problem. Since the CSI transaction, the Company has focused on the
software re-engineering market in general and the Year 2000 market in
particular. For financial reporting purposes, the CSI transaction has been
treated as a recapitalization of CSI with CSI as the acquirer (a reverse
acquisition).
 
  Prior to the recapitalization, in April 1996, CSI entered into a strategic
partnership with Fiserv Federal Systems, Inc. ("Fiserv Federal") to form
Fiserv Century Services Joint Venture (the "Joint Venture"). CSI and Fiserv
Federal each owned 50% of the Joint Venture. Fiserv Federal is part of Fiserv,
Inc., a publicly-held company that offers centralized data processing services
to financial institutions. The Joint Venture was engaged in the business of
marketing Year 2000 computer consulting services using computer software
exclusively licensed to CSI. As part of the CSI recapitalization, Fiserv
agreed to sell its interest in the Joint Venture to Old ZMAX. Since Old ZMAX's
acquisition of Fiserv Federal's interest in the Joint Venture, CSI has carried
on the operations of the Joint Venture. After the CSI recapitalization, Old
ZMAX transferred all of its interest in the Joint Venture to CSI as of January
1, 1997, and CSI, as the sole remaining venture partner, terminated the Joint
Venture. At this time, all of the Company's Year 2000 business is operated by
CSI.

                                  THE MERGER
 
THE MERGER
 
  Subject to the conditions summarized below, the Company will be
reincorporated in Delaware by merging Old ZMAX with and into New ZMAX (the
"Merger") pursuant to the Merger Agreement. New ZMAX will succeed to all the
business, properties, assets and liabilities of Old ZMAX, and the stockholders
of Old ZMAX will, upon surrender of their shares of Old ZMAX Common Stock for
exchange, become stockholders of New ZMAX. After the Merger, the rights of the
Company's stockholders will be governed by the Delaware Law and by the Amended
and Restated New ZMAX Certificate of Incorporation and Amended and Restated
Bylaws that will be adopted as part of the Merger, rather than by the Nevada
Law and the Old ZMAX Articles of Incorporation and Bylaws. A copy of the New
ZMAX Amended and Restated Certificate of Incorporation is attached as Annex B
(the "New ZMAX Certificate of Incorporation"), and a copy of the Amended and
Restated Bylaws is attached as Annex C (the "New ZMAX Bylaws").
 
RECOMMENDATIONS OF THE BOARD AND PRINCIPAL REASONS FOR THE MERGER AND THE
EXCHANGE OFFER
 
  To implement its business plan and achieve its strategic objective to
deliver high quality millennium services in a cost effective manner, the
Company will require significant amounts of cash, including equity capital, to
support its activities. In view of the Company's lack of profitable operations
coupled with its lack of experience in the millennium services business, the
Company believes that most potential investors would only be willing to
consider an investment in the form of a loan or in an equity security that has
preferential rights to the rights of Old ZMAX Common Stock in the event of
liquidation. In addition, any borrowing arrangement would likely bear interest
at a level substantially in excess of prevailing market rates that are
available to some of the Company's competitors, thereby putting the Company at
a competitive disadvantage in terms of its cost structure.
 
  The Company is undertaking the Exchange Offer in order to facilitate the
consummation of the restructuring contemplated by the Merger through the
retirement of outstanding debt of the Company, to improve the Company's debt
to equity ratio by decreasing total liabilities, increasing total
stockholders' equity and eliminating approximately $440,000 of annual interest
expense. The Debentures accrue interest at 8% per annum, payable semi-annually
commencing June 1, 1997. The Debentures may not be redeemed until the Company
has first made an exchange offer. Upon completion of the Exchange Offer, the
Company will have the option of (i) redeeming any remaining outstanding
Debentures at par through the date of redemption or (ii) paying interest on
the outstanding Debentures semi-annually until paying off the Debentures at
maturity in December 1999. To minimize any additional dilution upon the
conversion of Debentures not surrendered for exchange in the Exchange Offer,
the Company presently intends to redeem for cash any Debentures outstanding
promptly after completion of the Exchange Offer.
 
  In the Exchange Offer, each exchanging Debenture holder will also receive a
Warrant to purchase Old ZMAX Common Stock at a price of $7 per share through
the first anniversary of the completion of the Exchange Offer and thereafter
at $8 per share. The Warrants expire on the second anniversary of the
completion of the Exchange Offer. The obligation of Old ZMAX to consummate the
Merger is conditioned on the exchange of at least 90% of the Debentures and
the immediate exercise of Warrants issued in the Exchange Offer so that at
least 80% of the Warrant Shares are issued. As a result of this exchange and
exercise, the Company will issue at least 2,057,000 shares of Old ZMAX Common
Stock and receive in connection therewith at least $6.7 million in cash that
will be reflected on the Company's balance sheet as equity capital.
 
  As an incentive to induce Debenture holders to surrender their Debentures
for exchange in the Exchange Offer and to exercise their Warrants received in
connection with the Exchange Offer, Old ZMAX and New ZMAX have determined to
register the securities issuable in connection with the Exchange Offer and the
Merger under the Securities Act. Following the Merger, all shares of New ZMAX
Common Stock issued in the Merger will be freely transferable without
restriction or further registration under the Securities Act except for shares
beneficially owned by "affiliates" of the Company (as defined in Rule 144
under the Securities Act which,
 
                                      17
<PAGE>
 
generally speaking, includes all directors, executive officers and beneficial
owners of 10% or more of the Company's issued and outstanding common stock)
whose shares will be "restricted securities." Restricted securities generally
may only be sold in compliance with Rule 144. Absent registration of the New
ZMAX Common Stock to be issued in the Merger, all of the outstanding shares of
Old ZMAX converted subsequently into New ZMAX Common Stock would constitute
"restricted securities" under the Securities Act. The Company intends to apply
for the listing of the New ZMAX Common Stock on the Nasdaq SmallCap Market
effective upon completion of the Merger. See "The Exchange Offer--Exercise of
Warrants."
 
  In addition, as a result of the Merger, New ZMAX will be subject to the
periodic reporting requirements of the Exchange Act. Following the Merger, New
ZMAX will prepare and file with the Commission annual and quarterly reports on
forms prescribed by the Commission. Other information required by the
Commission such as proxy statements and reports regarding purchases and sales
of New ZMAX Common Stock by affiliates of New ZMAX also will be publicly
available. The Old ZMAX Board of Directors determined that the availability of
current public information relating to the Company along with the existence of
a market in which to execute purchases and sales of New ZMAX Common Stock will
provide a significant benefit to the investing market in general and New ZMAX
stockholders in particular. Furthermore, the foregoing factors should also
facilitate the ability of New ZMAX to access the capital markets in the future
in an expeditious manner and on more competitive terms than are currently
available to Old ZMAX.
 
  The Exchange Offer will result in converting approximately $5.5 million of
indebtedness into equity and the exercise of the Warrants will enable the
Company to benefit from the infusion of at least $6.7 million in new equity
capital. The Old ZMAX Board also concluded that there were not any alternative
transactions available to Old ZMAX at the present time that would provide the
same benefits as will be realized from the Exchange Offer, the exercise of the
Warrants and the Merger. In addition, the Company believes that any
alternative transaction would almost certainly be subject to a number of
contingencies and would have been unlikely to be capable of being accomplished
as expeditiously as the Exchange Offer, the exercise of the Warrants and the
Merger.
 
  In considering the Merger, the Board of Directors determined that the best
interests of the Company will be served by changing the state of incorporation
of the Company from Nevada to Delaware. As the Company plans for the future,
the Board of Directors and management believe that it is essential to be able
to draw upon well established principles of corporate governance in making
legal and business decisions. The prominence and predictability of Delaware
corporate law provide a reliable foundation on which the Company's governance
decisions can be based. The Company believes that its stockholders will
benefit from the responsiveness of Delaware corporate law to their needs and
to those of the Company. The advantages of Delaware corporate law are
described below.
 
ADVANTAGES OF DELAWARE CORPORATE LAW
 
  By changing the state of incorporation of the Company from Nevada to
Delaware, the Company will receive the following advantages:
 
  Prominence, Predictability and Flexibility of Delaware Law. For many years,
Delaware has followed a policy of encouraging incorporation in that state. In
furtherance of that policy, Delaware has been a leader in adopting, construing
and implementing comprehensive, flexible corporate laws responsive to the
legal and business needs of corporations organized in Delaware. Many
corporations have chosen Delaware initially as a state of incorporation or
have subsequently changed corporate domicile to Delaware. Because of
Delaware's prominence as the state of incorporation for many major
corporations, both the legislature and courts in Delaware have demonstrated an
ability and a willingness to act quickly and effectively to meet changing
business needs. The Delaware courts have developed considerable expertise in
dealing with corporate issues and a substantial body of case law has developed
construing Delaware law and establishing public policies with respect to
corporate legal affairs.
 
  Increased Ability to Attract and Retain Qualified Directors. Both Nevada and
Delaware law permit a corporation to include a provision in its charter that
reduces or limits the monetary liability of directors for breaches of
fiduciary duty in certain circumstances. The Company believes that, in
general, Delaware case law regarding a corporation's ability to limit director
liability is more developed and provides more guidance than Nevada law. The
increasing frequency of claims and litigation directed against directors has
greatly
 
                                      18
<PAGE>
 
expanded the risks facing directors of corporations in exercising their
respective duties. The amount of time and money required to respond to such
claims and to defend such litigation can be substantial. It is the Company's
desire to reduce these risks to its directors and to limit situations in which
monetary damages can be recovered against directors so that the Company may
continue to attract and retain qualified directors who otherwise might be
unwilling to serve because of the risks involved.
 
  Well Established Principles of Corporate Governance. There is substantial
judicial precedent in the Delaware courts as to the legal principles
applicable to measures that may be taken by a corporation and as to the
conduct of the Board of Directors under the business judgment rule. The
Company believes that its stockholders will benefit from the well established
principles of corporate governance that Delaware law affords.
 
  No Change in Board Members, Business, Management, Employee Benefit Plans or
Location of Principal Facilities of the Company. The reincorporation achieved
by the Merger will effect only a change in the legal domicile of the Company
and certain other changes of a legal nature, certain of which are described in
this Proxy Statement/Prospectus. The reincorporation contemplated by the
Merger will NOT result in any change in the business, management, fiscal year,
assets or liabilities (except to the extent of legal and other costs of
effecting the Merger) or location of the principal facilities of the Company.
 
VOTE REQUIRED FOR THE MERGER
 
  Pursuant to the Nevada Law, the affirmative vote of the holders of at least
a majority of the shares of Old ZMAX Common Stock outstanding as of the Record
Date and entitled to vote are required to approve and adopt the Merger
Agreement and the transactions contemplated thereby. At the Record Date, there
were 9,450,514 shares of Old ZMAX Common Stock outstanding. Approval of the
Merger will also constitute approval of the New ZMAX Certificate of
Incorporation and New ZMAX Bylaws.
 
THE MERGER AGREEMENT
 
  The following is a summary of certain provisions of the Merger Agreement and
related matters. The Merger Agreement is attached at Annex A hereto.
 
  Conversion of Shares. Upon the effectiveness of the Merger, each outstanding
share of Old ZMAX Common Stock will be automatically converted into the right
to receive, upon surrender, one share of New ZMAX Common Stock, and each
outstanding share of New ZMAX Common Stock will be cancelled. Because of the
one-for-one Merger exchange ratio, no fractional shares of New ZMAX Common
Stock will be issued in the Merger.
 
  Exchange of Stock Certificates. From and after the Effective Time, each
share of Old ZMAX Common Stock will be automatically converted into the right
to receive one share of New ZMAX Common Stock. As soon as practicable after
the Effective Time, New ZMAX will send transmittal instructions to each former
Old ZMAX stockholder describing the procedure for surrendering Old ZMAX stock
certificates for New ZMAX stock certificates. COMPANY STOCKHOLDERS SHOULD NOT
SEND IN THEIR STOCK CERTIFICATES UNTIL THEY RECEIVE A TRANSMITTAL FORM.
 
  Conditions to the Merger. The Merger is subject to the satisfaction or
waiver of the following conditions: (i) approval of the Merger by the
stockholders of Old ZMAX, (ii) at least 90% of the Debentures will have been
exchanged in the Exchange Offer and (iii) Warrants issued in the Exchange
Offer for at least 80% of the Warrant Shares will have been exercised at the
exercise price received.
 
  Effective Time. After all the conditions set forth in the Merger Agreement
have been satisfied or waived, the Merger will become effective at such time
as a Certificate of Merger required under the Nevada Law and the Delaware Law
is filed with the Secretaries of State of the States of Nevada and Delaware.
Such filing will be made simultaneously with or as soon as practicable after
the closing of the transactions contemplated by the Merger Agreement.
 
  Termination; Amendment. The Merger Agreement may be terminated or abandoned
by the Board of Directors of Old ZMAX or New ZMAX at any time prior to the
filing of the certificate of merger with the Secretary of State of Nevada or
Delaware. The Board of Directors of Old ZMAX and New ZMAX may jointly amend,
modify and supplement the Merger Agreement in such manner as they may deem
appropriate at any time before approval or adoption of the Merger Agreement by
Old ZMAX stockholders. Any amendment, modification or supplement to the Merger
Agreement after the approval or adoption by the Old ZMAX
 
                                      19
<PAGE>
 
stockholders but prior to the Effective Time of the Merger will require
approval or adoption by the Old ZMAX stockholders. However, approval or
adoption by the Old ZMAX stockholders will not be required with respect to any
amendment, modification or supplement to the Merger Agreement that (i) does not
alter (a) the amount or kind of shares or rights to be received under the
Merger Agreement in exchange for any of the shares of the Old ZMAX Common
Stock, or (b) any term of the New ZMAX Certificate of Incorporation as provided
for in the Merger Agreement, or (ii) otherwise alters any of the terms and
conditions of the Merger Agreement if such alteration would not adversely
affect the holders of the Old ZMAX Common Stock.
 
INTERESTS OF CERTAIN PERSONS
 
  None of Old ZMAX's directors, director nominees or executive officers have
any material interest in the Merger other than their respective pro rata
interest as a result of their beneficial ownership of Old ZMAX Common Stock. No
option or employee benefit will vest or accelerate as a result of the Merger.
None of Old ZMAX's directors, director nominees or executive officers, directly
or indirectly, hold any Debenture. As of the Record Date, Old ZMAX's current
directors, executive officers and their affiliates owned [1,867,942] shares of
Old ZMAX Common Stock entitled to vote at the Meeting (representing [19.8%] of
the outstanding Old ZMAX Common Stock), and each of such individuals have
indicated their intention to cause these shares to be voted in favor of the
Merger Agreement and the transactions contemplated by the Merger Agreement.
These individuals also hold options for an additional 124,000 shares of Old
ZMAX Common Stock that are currently exercisable. In addition, pursuant to the
Company's Directors Formula Stock Option Plan, one of the Company's director
nominees will be entitled to receive options for 12,000 shares of Old ZMAX
Common Stock upon his election to the Board of Directors, 8,000 of which will
be currently exercisable.
 
DISSENTERS' RIGHTS
 
  Old ZMAX stockholders who oppose the proposed Merger will have the right to
receive payment for the value of their shares as set forth in Sections 92A.300
through 92A.500 of the Nevada Law attached as Annex D. Such dissenters' rights
will be available only to stockholders of Old ZMAX who (i) before the vote to
authorize the Merger, notify Old ZMAX in writing of their intention to demand
payment for their shares of Old ZMAX Common Stock and (ii) refrain from voting
in favor of the Merger. Voting against the Merger will not constitute notifying
Old ZMAX of the intention to demand payment if the Merger is effectuated.
 
  A stockholder must exercise dissenters' rights for all of the shares that he
or she owns of record. A stockholder who holds shares beneficially, and not of
record, may assert dissenter's rights for the beneficially owned shares only by
submitting a written consent of the stockholder of record along with the
written notice of dissent. A stockholder exercising dissenter's rights with
respect to shares that he or she owns beneficially may not exercise dissenter's
rights for fewer than all the shares held by the owner of record.
 
  Since the vote to authorize the Merger will take place at the Meeting, Old
ZMAX will be required to notify by mail those stockholders who, by virtue of a
timely notice of their intention to demand payment and having refrained from
voting in favor of the Merger, are entitled to payment for their shares
("Dissenters Notices"). Dissenters Notices must be sent no later than ten days
after consummation of the Merger. The notice must (i) state where demand for
payment must be sent, (ii) state when certificates must be deposited, (iii)
state the restrictions on transfer of shares that are not evidenced by a
certificate once demand has been made, (iv) supply a form on which to demand
payment, (v) set a date by which demand must be received, and (vi) include a
copy of the relevant portions of the Nevada Law.
 
  Unless a stockholder acquired his or her shares after Old ZMAX sends the
Dissenters Notices, Old ZMAX must calculate the fair market value of the shares
plus interest, and within 30 days of the date Old ZMAX receives the demand, pay
this amount to any stockholder that properly exercised dissenters' rights and
deposited certificates with Old ZMAX. If Old ZMAX does not pay within 30 days,
a stockholder may enforce in court Old ZMAX's obligation to pay. The payment
must be accompanied by (i) Old ZMAX's interim balance sheet, (ii) a statement
of the fair market value of the shares, (iii) an explanation of how the
interest was calculated, (iv) a statement of dissenters' right to demand
payment, and (v) a copy of the relevant portions of the Nevada Law.
 
  Within 30 days of when the Company pays a dissenting stockholder for his or
her shares, the stockholder has the right to challenge the Company's
calculation of the fair market value of the shares and interest due, and
 
                                       20
<PAGE>
 
must state the amount that he or she believes to represent the true fair
market value and interest of the shares. If the Company and the stockholder
are not able to settle on an amount, the Company may petition a court within
60 days of making payment to the dissenting stockholder. If the Company does
not either settle with the stockholder or petition a court for a determination
within 60 days, the Company is obligated to pay the stockholder the amount
demanded that exceeds the Company's calculation of fair market value plus
interest. All dissenters are entitled to judgment for the amount by which the
fair market value of their shares is found to exceed the amount previously
remitted, with interest.
 
  If beneficial owners of more than 5% of the issued and outstanding shares of
Old ZMAX Common Stock exercise their dissenters' rights, the Company may
determine to abandon the Merger. See "The Merger--The Merger Agreement--
Conditions to the Merger."
 
CHANGES AFFECTING STOCKHOLDERS
 
  Differences between Nevada and Delaware law will result in certain changes
affecting stockholders. For a discussion of certain significant differences
between Nevada and Delaware law, see "Comparison of Stockholders Rights."
 
  The New ZMAX Certificate of Incorporation that will be adopted as part of
the Merger is substantially similar to the Articles of Incorporation of Old
ZMAX in all material respects, except that the New ZMAX Certificate of
Incorporation will (i) provide for a classified Board of Directors with
staggered terms, (ii) consistent with the Delaware Law, limit the liability to
the Company of only directors, as opposed to the Old ZMAX limitation for both
directors and officers, and (iii) consistent with the Delaware Law, obligate
the Company to indemnify only directors, as opposed to Old ZMAX's obligation
to indemnify officers, employees and agents as well. In this regard, it should
be noted that the New ZMAX Board of Directors retains the discretionary
authority to authorize the indemnification of officers, employees and agents,
subject to certain conditions under the Delaware Law. A copy of the New ZMAX
Certificate of Incorporation is included as Annex B hereto.
 
  The New ZMAX Bylaws that will be adopted as part of the Merger is the same
as the Bylaws of Old ZMAX in all material respects, except that the New ZMAX
Bylaws (i) implement the classified board adopted in the Certificate of
Incorporation, (ii) increase from 10% to 25% the number of issued and
outstanding shares of the Company's common stock that must be beneficially
owned by stockholders seeking to call a special meeting of the stockholders,
(iii) prohibit the stockholders from taking action by written consent, and
(iv) provide certain changes necessary to conform to Delaware law. See
"Comparison of Stockholder Rights." A copy of the New ZMAX Bylaws is included
as Annex C hereto.
 
FEES AND EXPENSES
 
  The expenses of the Merger, will be borne by the Company. The expenses
include soliciting stockholder approval, offering the Exchange Offer to the
Debenture holders, SEC registration fees, NASD listing fees, and legal,
accounting and printing fees. The solicitation of stockholders and Debenture
holders is being made by mail. However, additional solicitation may be made by
fax, telephone or in person by officers and regular employees or consultants
of the Company.
 
  The total cash expenditures to be incurred by the Company in connection with
the Merger and the Exchange Offer are estimated to be approximately $     .
 
U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER
 
  The following is a summary of the material U.S. federal income tax
consequences of the Merger to Old ZMAX and its stockholders.
 
  The merger of Old ZMAX into New ZMAX, as described above, will constitute a
tax-free reorganization within the meaning of Section 368(a)(1)(F) of the
Internal Revenue Code of 1986, as amended, (the "Code"). For federal income
tax purposes:
 
    (1) Neither Old ZMAX nor its stockholders will recognize any gain or loss
  by reason of the exchange of Old ZMAX Common Stock for New ZMAX Common
  Stock, the deemed exchange of the Old ZMAX Warrants for New ZMAX Warrants
  (to the extent not exercised prior to the Merger) or the transfer of assets
  (subject to liabilities) by Old ZMAX to New ZMAX in connection with the
  Merger.
 
 
                                      21
<PAGE>
 
    (2) The shares of New ZMAX Common Stock and Warrants issued as a result
  of the Merger in the hands of a stockholder will have an aggregate basis
  for computing gain or loss equal to the aggregate basis of shares of Old
  ZMAX Common Stock (less that portion, if any, allocable to fractional
  shares) and Warrants held by that stockholder immediately prior to the
  Merger.
 
    (3) The holding period of the shares of New ZMAX Common Stock and
  Warrants issued as a result of the Merger in the hands of a stockholder
  will include the period during which the stockholder held the shares of Old
  ZMAX Common Stock and Warrants, respectively, prior to the Merger provided
  the shares of Old ZMAX Common Stock and Warrants were each held as a
  capital asset at the effective time of the Merger.
 
    (4) A stockholder who receives solely cash pursuant to such stockholder's
  statutory dissenters or appraisal right will be treated as having received
  such payment in redemption of such stockholder's Old ZMAX Common Stock, as
  provided in Section 302(a)(1) of the Code. Each affected stockholder is
  urged to consult such stockholder's own tax advisor for the effect of such
  redemption (i.e., exchange or dividend treatment) in light of such
  stockholder's particular facts and circumstances.
 
  The tax analysis and conclusions stated above are limited to certain U.S.
federal income tax consequences of the Merger. Tax consequences to foreign
persons may vary depending on the law of the applicable jurisdiction. Each
stockholder is urged to consult such stockholder's tax advisor to determine
the specific tax consequences of the Merger to such stockholder.
                              THE EXCHANGE OFFER
 
 
  The Company is making the following Exchange Offer to holders of Debentures.
TERMS OF THE EXCHANGE OFFER
 
 
  Old ZMAX hereby offers, upon the terms and subject to the conditions set
forth in this Proxy Statement/Prospectus and the accompanying Letter of
Transmittal, to each holder of Debentures the opportunity to exchange all, but
not less than all, Debentures held for (i) 220 shares of Old ZMAX Common Stock
and (ii) a Warrant to purchase 220 shares of Old ZMAX Common Stock
(collectively, the "Exchange Consideration") for each $1,000 principal amount
of Debentures. No payment or adjustment will be paid in respect of accrued and
unpaid interest from June 1, 1997 (the most recent interest payment date) to
the date of exchange. Tendering Debenture holders will receive the Exchange
Consideration in lieu of any payment in respect of accrued and unpaid
interest. As of the date of this Proxy Statement/Prospectus, $5.5 million
aggregate principal amount of Debentures were outstanding. Assuming all of the
outstanding Debentures are validly tendered and accepted for exchange,
tendering holders of Debentures will receive an aggregate of 1,210,000 shares
of authorized but previously unissued Old ZMAX Common Stock plus Warrants to
purchase an additional 1,210,000 shares of Old ZMAX Common Stock. Pursuant to
the terms of the Debentures and because the Debentures are issued in integral
multiples of $1,000, no fractional shares will be issued in the Exchange
Offer.
 
  The Company presently intends to redeem for cash any Debenture remaining
outstanding following completion of the Exchange Offer at 100% of principal
amount thereof plus any interest accrued thereon to the date of redemption.
The Company anticipates that all of the Debentures will be tendered in the
Exchange Offer because the market price of the Exchange Consideration per
$1,000 principal amount of Debentures exceeds $1,000 and the redemption price.
In addition, as a result of the Merger, Old ZMAX Common Stock received by
tendering holders of Debentures in the Exchange Offer and upon exercise of
Warrants prior to the Effective Time of the Merger would be converted into
shares of New ZMAX Common Stock which would not be "restricted securities"
under the Securities Act. By contrast, the Debentures and Old ZMAX or New ZMAX
Common Stock issuable upon conversion thereof (rather than pursuant to the
Exchange Offer) would be restricted securities.
 
  Old ZMAX has the right, but not the obligation, to waive or amend the terms
of the Exchange Offer or extend the Exchange Offer, provided that any modified
consideration will be provided to all tendering holders, even if they tendered
their Debentures prior to the modification. Any amendment applicable to the
Exchange Offer will apply to all Debentures exchangeable in the Exchange
Offer, regardless of when or in what order such Debentures were tendered.
 
 
                                      22
<PAGE>
 
PURPOSES AND EFFECTS OF THE EXCHANGE OFFER
 
  The Company is undertaking the Exchange Offer in order to facilitate the
consummation of the restructuring contemplated by the Merger through the
retirement of outstanding debt of the Company, to improve the Company's debt
to equity ratio by decreasing total liabilities, increasing total
stockholders' equity and eliminating approximately $440,000 of annual interest
expense.
 
  Under generally accepted accounting principles, because the Exchange
Consideration includes securities in excess of the securities issuable
pursuant to the original conversion terms of the Debentures, the Company will
be required to recognize as expense the fair value of the securities issuable
upon the exchange of the Debentures in excess of the fair value of the
securities issuable pursuant to the original conversion terms of the
Debentures. Accordingly, the Company will recognize an expense equal to (i)
the fair value of the incremental number of shares of Old ZMAX Common Stock
issued in the exchange in excess of the number of shares of Old ZMAX Common
Stock issuable upon conversion of the Debentures in accordance with their
terms plus (ii) the fair value of the Warrants issued in the exchange. As a
result, assuming all of the Debentures are tendered and accepted for exchange
pursuant to the Exchange Offer, and assuming that the fair market value of the
Old ZMAX Common Stock is $14.375 (the closing price on June 18, 1997 as quoted
on the OTC Bulletin Board) on the date of the exchange, the Company will
recognize an expense of approximately $10.5 million upon consummation of the
Exchange Offer in the third quarter of 1997. Including the effect of that
expense, the net effect of the Exchange Offer would increase stockholders'
equity by $12.2 million. See "Capitalization" and " Unaudited Pro Forma
Financial Data."
 
EXPIRATION DATE; EXTENSIONS; TERMINATION; AMENDMENTS
 
  The Exchange Offer will expire at 5:00 p.m., Eastern Standard Time, on
September  , 1997 [21st business day after commencement], unless the Company,
in its sole discretion, extends the Exchange Offer. During any extensions, all
Debentures previously validly tendered pursuant to the Exchange Offer and not
yet accepted will remain subject to the Exchange Offer (subject to withdrawal
rights specified herein). The later of 5:00 p.m., Eastern Standard Time on
September  , 1997, or the latest time and date to which the Exchange Offer may
be extended is referred to herein as the "Expiration Date."
 
  The Company expressly reserves the right, at any time or from time to time,
to extend the period of time for which the Exchange Offer is to remain open.
Any extension or expiration of the Exchange Offer will be followed as promptly
as practicable by the sending of notice of such extension or expiration to the
holders of the Debentures by first class mail, fax or otherwise.
 
  The Exchange Offer may be amended at any time. If the Company makes a
material change in the terms of the Exchange Offer or in the information
concerning the Exchange Offer or if it waives a material condition of the
Exchange Offer, the Company will disseminate additional Exchange Offer
material and will extend the Exchange Offer in each case to the extent
required by law.
 
  The Company reserves the right, in its sole discretion, to terminate the
Exchange Offer at any time prior to the consummation thereof. See "--
Conditions of the Exchange Offer."
 
PROCEDURES FOR TENDERING DEBENTURES
 
  For the Debentures to be effectively tendered pursuant to the Exchange
Offer, a Letter of Transmittal (or a facsimile thereof) that has been properly
completed and duly executed by the registered holder thereof, and any other
documents required by the Letter of Transmittal, must be received by the
Exchange Agent at its address set forth herein. In order for a holder of the
Debentures to participate in the Exchange Offer, the Debenture holder must
return these documents on or before the Expiration Date. The Letter of
Transmittal should be sent only to the Exchange Agent. See "--Letter of
Transmittal" and "--Exchange Agent and Information Source."
 
ACCEPTANCE OF DEBENTURES FOR EXCHANGE AND DELIVERY OF THE EXCHANGE
CONSIDERATION
 
  Upon the terms and subject to the conditions of the Exchange Offer,
acceptance of the Debentures validly tendered under the Exchange Offer and not
withdrawn, and delivery of certificates representing the Old ZMAX Common Stock
and Warrants in exchange for the Debentures will be made as promptly as
practicable after the
 
                                      23
<PAGE>
 
Expiration Date. The Company, however, expressly reserves the right to delay
acceptance of any of the Debentures or to terminate the Exchange Offer and not
accept for exchange any Debentures not already accepted if any conditions set
forth under "--Conditions of the Exchange Offer" are not satisfied and have
not been waived by the Company. For purposes of the Exchange Offer, the
Company will be deemed to have accepted for exchange validly tendered
Debentures upon execution of a written acceptance thereof. See "--Conditions
of the Exchange Offer."
 
LETTER OF TRANSMITTAL
 
  The Letter of Transmittal notifies each Debenture holder of the Exchange
Offer and must be completed and returned by the Debenture holder to
participate in the Exchange Offer. The Letter of Transmittal contains, among
other things, the following terms and conditions, which are part of the
Exchange Offer.
 
  The party tendering the Debentures for exchange (the "Transferor") assigns
the Debentures to the Company and irrevocably appoints the Exchange Agent as
the Transferor's agent and attorney-in-fact to cause the Debentures to be
assigned and exchanged. The Transferor represents that it has full power and
authority to tender and assign the Debentures, and that, when the same are
accepted for exchange, the Company will acquire good and unencumbered title to
the tendered Debentures. The Transferor also represents that it will, upon
request, execute and deliver any additional documents requested by the Company
to complete the assignment and exchange of tendered Debentures. All authority
conferred by the Transferor to the Exchange Agent will survive the death,
bankruptcy or incapacity of the Transferor and every obligation of the
Transferor will be binding upon the heirs, personal representatives,
successors and assigns of the Transferor.
 
CONDITIONS OF THE EXCHANGE OFFER
 
  Notwithstanding any other provision of the Exchange Offer, the Company is
not required to accept for exchange or, subject to any applicable rules and
regulations of the SEC, exchange any Debentures tendered and may postpone the
acceptance of or, subject to the restrictions set forth above, may terminate
or amend the Exchange Offer if, at any time prior to the time of acceptance
for exchange or issuance of the Exchange Consideration in respect of any such
Debentures (whether or not any other Debentures have already been accepted for
exchange and payment or paid for pursuant to the Exchange Offer), any of the
following events occur:
 
    (a) the holders of the requisite number of shares of Old ZMAX Common
  Stock do not approve the Merger Agreement and the transactions contemplated
  thereby at the Meeting; or
 
    (b) any change (or any condition, event or development involving a
  prospective change) occurs or is threatened in the business, properties,
  assets, liabilities, capitalization, shareholders' equity, financial
  condition, operations, results of operations or prospects of Old ZMAX or
  any of its subsidiaries, or in the general economic or financial market
  conditions in the United States or abroad, that, in the sole judgment of
  the Company, is or may be materially adverse to Old ZMAX and its
  subsidiaries or its stockholders or to the value of the Debentures or the
  Old ZMAX Common Stock or there is a significant decrease in the market
  prices of or trading in the Common Stock, or the Company becomes aware of
  any fact or occurrence which, in the sole judgment of the Company, is or
  may be materially adverse with respect to the value of the Debentures or
  the Exchange Offer's contemplated benefits to the Company; or
 
    (c) there occurs (1) any general suspension of trading in, or limitation
  on prices for, securities on any national securities exchange or the over-
  the-counter market, (2) a declaration of a banking moratorium or any
  suspension of payments in respect of banks in the United States, (3) a
  declaration of a national emergency or a commencement of a war, armed
  hostilities or other national or international calamity directly or
  indirectly involving the United States, (4) any limitation (whether or not
  mandatory) by any governmental or regulatory authority on, or any other
  event which in the sole judgment of the Company might affect, the nature or
  extension of credit by banks or other financial institutions, (5) any
  significant adverse change in the United States securities or financial
  markets, or (6) in the case of any of the foregoing existing at the time of
  the commencement of the Exchange Offer, in the sole judgment of the
  Company, a material acceleration, escalation or worsening thereof; or

    (d) any action is taken or threatened, or any statute, rule, regulation,
  judgment, order or injunction proposed, sought, promulgated, enacted,
  entered, enforced or deemed applicable to the Exchange Offer by any
  government or governmental authority or by any court, that, in the sole
  judgment of the Company, might, directly or indirectly, (1) make the
  acceptance for exchange for some or all of the Debentures illegal or
  otherwise restrict or prohibit consummation of the Exchange Offer, (2)
  result in a delay in, or restrict the ability of the Company, or render the
  Company unable, to accept for exchange some or all of the Debentures, (3)
  otherwise adversely affect Old ZMAX or any of its subsidiaries or
  affiliates or (4) result in a material limitation in the benefits expected
  to be derived by the Company as a result of the transactions contemplated
  by the Exchange Offer; or
 
    (e) there is threatened, instituted or pending any action, proceeding or
  claim by or before any court or governmental, administrative or regulatory
  agency or authority or any other person or tribunal, domestic or foreign,
  challenging the making of the Exchange Offer, the acquisition by the
  Company of any Debentures, or seeking to obtain any material damages as a
  result thereof, or, in the sole judgment of the Company, otherwise
  adversely affecting Old ZMAX or any of its subsidiaries or affiliates or
  the value of the Debentures or the Old ZMAX Common Stock;
 
that, in the sole judgment of the Company in any such case, and regardless of
the circumstances (including any action or omission by Old ZMAX or any of its
affiliates or subsidiaries) giving rise to any such condition, makes it
inadvisable to proceed with the Exchange Offer or such acceptance for exchange
of Debentures.
 
  All of the foregoing conditions are for the sole benefit of the Company and
may be asserted by the Company regardless of the circumstances giving rise to
such condition and may be waived by the Company, in whole or in part, at any
time and from time to time, in the sole discretion of the Company. The failure
of the Company at any time to exercise any of the foregoing rights will not be
deemed to be a waiver of any such right, and each such right will be deemed an
ongoing right which may be asserted at any time and from time to time. Any
determination by the Company concerning the foregoing conditions is final and
binding.
 
  If any of the foregoing conditions are not satisfied (or, with respect to
the above enumerated events, has occurred), the Company may, subject to
applicable law, (i) terminate the Exchange Offer and return all Debentures
tendered pursuant to the Exchange Offer to tendering Debenture holders; (ii)
extend the Exchange Offer and retain all tendered Debentures until the
Expiration Date for the extended Exchange Offer; or (iii) waive the
unsatisfied conditions with respect to the Exchange Offer and accept all
Debentures tendered pursuant to the Exchange Offer.
 
CERTAIN CONSEQUENCES TO TENDERING AND NONTENDERING HOLDERS
 
  The Old ZMAX Common Stock received by tendering holders of Debentures that
are accepted for exchange and upon exercise of Warrants will, as an equity
security, be junior in right of payment to all existing and future
indebtedness of the Company, including Debentures not tendered or not accepted
for exchange, and will also be junior in right of payment to any preferred
stock of the Company which by its terms is senior in right of payment to the
Common Stock. As of the date of the Proxy Statement/Prospectus the Company
does not have any preferred stock outstanding and does not have any plans,
arrangements or understandings regarding the issuance of any preferred shares.
See "Description of Securities." Dividends on the Old ZMAX Common Stock are
payable when, as and if declared by the Board of Directors of Old ZMAX. The
Company has not paid cash dividends on its Common Stock and does not expect to
do so in the foreseeable future. The Company presently intends to redeem for
cash any Debenture remaining outstanding following completion of the Exchange
Offer at 100% of principal amount thereof plus any interest accrued thereon to
the date of redemption.
 
WITHDRAWAL RIGHTS
 
  All tenders duly and validly made under the Exchange Offer may be withdrawn
at any time on or before 5:00 p.m., Eastern Standard Time, September  , 1997.
Holders of Debentures who wish to exercise this right of
 
                                      25
<PAGE>
 
withdrawal must give notice of withdrawal in writing or by telegram, telex or
fax, which notice must be timely received by the Exchange Agent at its address
set forth herein. Any notice of withdrawal must specify the name of the person
who tendered the Debentures to be withdrawn and the principal amount of the
Debentures to be withdrawn. The notice of withdrawal must be signed by the
holder of the Debentures in the same manner as the original signature on the
Letter of Transmittal (including any required signature guarantees) or be
accompanied by evidence satisfactory to the Company that the person
withdrawing the tender has succeeded to the beneficial ownership of the
Debentures.
 
  All questions as to the validity (including time of receipt) of notices of
withdrawal will be determined by the Company, in its sole discretion, which
determination is final and binding. Neither the Company nor any other person
will be under any duty to give notification of any defects or irregularities
in any notice of withdrawal or incur any liability for failure to give any
such notification.
 
EXERCISE OF WARRANTS
 
  Tendering holders of Debentures who exercise their Warrants prior to the
Merger will receive New ZMAX Common Stock in the Merger if the Merger is
approved by the Old ZMAX stockholders. These shares of New ZMAX Common Stock
received by the Debenture holders will generally be freely transferable
without restriction or further registration under the Securities Act, except
that any shares held by "affiliates" of the Company (as defined in Rule 144
under the Securities Act) may generally only be sold in compliance with the
limitations of Rule 144.
 
  Although the Registration Statement of which this Proxy Statement/Prospectus
is a part registers the Warrants and Old ZMAX Common Stock issuable upon
exercise thereof, the Registration Statement will not remain current and in
effect significantly beyond the Effective Time of the Merger. Following the
Effective Time of the Merger, holders of Warrants must provide the Company
with certain representations and documentation relating the availability of an
exemption from the registration requirements of the Securities Act as a
condition to the valid exercise of Warrants. New ZMAX Common Stock issued in
respect of Warrants exercised following the Effective Time of the Merger will
generally be restricted securities. Since New ZMAX Common Stock issued in the
Merger following the exercise of Warrants for Old ZMAX Common Stock prior to
the Merger will generally not be restricted securities, the Company
anticipates that a substantial portion of the Warrants will be exercised prior
to the Effective Time of the Merger and the exchange of at least 90% of the
Debentures and the exercise of the Warrants for at least 80% of the Warrant
Shares are conditions to the Merger.
 
  The Company intends to use the proceeds from the exercise of Warrants for
working capital and general corporate purposes.
 
TRANSFER TAXES
 
  The holder of the Debenture must pay any transfer taxes applicable to the
transfer and exchange of Debentures for the Exchange Consideration pursuant to
the Exchange Offer. The amount of any such transfer taxes (whether imposed on
the tendering holder or any other person) will be payable by the tendering
holder prior to the issuance of the Exchange Consideration.
 
U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE EXCHANGE
 
  The following is a summary of the material U.S. federal income tax
consequence of the exchange pursuant to the Exchange Offer. The exchange of
Debentures for Old ZMAX Common Stock and Warrants in the Exchange Offer (the
"Exchange") should qualify as a tax-free recapitalization within the meaning
of Section 368(a)(1)(E) of the Code or as a tax-free conversion of the
Debentures under the authority of Revenue Ruling 72-265 (1972-2 C.B. 222) and
Treasury Regulation Section 1.1001-3(c)(1)(ii) and (2)(ii).
 
  Although the Exchange Offer is structured as a Section 368(a)(1)(E)
recapitalization, the Exchange will constitute a tax-free recapitalization
only if the Debentures constitute securities within the meaning of Section 354
of the Code. The determination of whether a debt instrument constitutes a
security involves a factual inquiry
 
                                      26
<PAGE>
 
relating to the nature of the debt. Generally, debt instruments with a
maturity date of less than five years from issuance are less likely to be
characterized as securities absent the presence of other factors indicating
the existence of a proprietary interest in the issuer. Thus, although term is
an important factor, the controlling consideration is more likely to be the
overall evaluation of the debt, degree of participation and continuing
interest in the business, the extent of proprietary interest compared with the
similarity of the note to a cash payment and the purpose of the advances.
Although convertibility of the Debentures into Old ZMAX Common Stock and
Warrants should make the classification of the Debentures as securities more
likely, the three year term of the Debentures may prevent such classification.
 
  In the event the Debentures do not constitute securities under Section 354
of the Code, the Exchange nonetheless should qualify as a tax-free conversion.
Generally, in the absence of a nonrecognition provision under the Code,
Section 1001 of the Code provides that the exchange of property (e.g., the
Debentures) for other property (e.g., Old ZMAX Common Stock and Warrants)
differing materially either in kind or in extent requires gain or loss to be
recognized. Under Revenue Ruling 72-265 and Treasury Regulation Section
1.1001-3, the conversion of a debt instrument into equity of the issuer of the
debt instrument will not result in a taxable exchange for purposes of Section
1001 of the Code where the conversion is pursuant to a conversion privilege
contained in the debt instrument when it was issued. Thus, the receipt of Old
ZMAX Common Stock upon conversion of the Debentures should not constitute a
taxable exchange. The receipt of the Warrants upon conversion of the
Debentures, also should not constitute a taxable exchange provided the
Warrants are deemed to constitute an equity interest in Old ZMAX. Proposed
Treasury Regulations have been issued relating to the receipt as part of a
reorganization, of rights to acquire stock of a party to the reorganization.
The Treasury indicated that although a right to acquire stock is not stock,
such right generally represents a form of investment in the capital structure
of the corporation that justifies nonrecognition treatment of the right as a
security. Based on this rationale and the provisions of Treasury Regulation
Section 1.1001-3, the Warrants received upon conversion of the Debentures
should be deemed to represent a form of investment (equity) in the capital
structure of Old ZMAX and should not result in recognition of gain or loss to
the Debenture holders. Nonetheless, the legal authority regarding this issue
is sufficiently uncertain such that the Warrants may be deemed other property
for purposes of Section 1001 thereby resulting in a taxable exchange with
respect to the receipt of the Warrants. Any gain resulting from the receipt of
the Warrants would constitute capital gain provided the Debentures exchanged
constituted capital assets. Capital gain of a foreign Debenture holder
resulting from receipt of Warrants should not be included in taxable income
unless the gain constitutes U.S. source income which is effectively connected
with a U.S. trade or business or such holder is present in the U.S. for at
least 183 days in the tax year.
 
  Whether the Exchange constitutes a tax-free recapitalization within the
meaning of Section 368(a)(1)(E) of the Internal Revenue Code or a tax-free
conversion under the authority of Revenue Ruling 72-265 and Treasury
Regulation Section 1.1001-3, the following U.S. federal income tax
consequences should result:
 
    (1) Neither Old ZMAX nor the Debenture holders will recognize any gain or
  loss by reason of the conversion of Debentures into Old ZMAX Common Stock
  and Warrants.
 
    (2) The Old ZMAX Common Stock and the Warrants received by a Debenture
  holder upon the Exchange will have an aggregate basis equal to the
  aggregate basis of the Debentures held by the Debenture holder immediately
  prior to the Exchange.
 
    (3) The holding period of the Old ZMAX Common Stock and the Warrants
  issued upon the Exchange will include the period during which the Debenture
  holder held the Debentures prior to the Exchange provided the Debentures
  were held as a capital asset upon the Exchange.
 
  The tax analysis and conclusions stated above are limited to certain U.S.
federal income tax consequences of the Exchange. Tax consequences to foreign
persons may vary depending on the law of the applicable jurisdiction. Each
Debenture holder is urged to consult such holder's tax advisor to determine
the specific tax consequences of the Exchange to such holder.

(A) Actual includes 479,801 shares held of record by certain stockholders that
    are subject to cancellation agreements with the Company but have not been
    surrendered for cancellation. See "Description of Securities--Cancellation
    of Certain Shares."
 
(B) Pro Forma assumes that the Company's Debentures are fully exchanged in the
    Exchange Offer for 1,210,000 shares of Old ZMAX Common Stock and Warrants
    to purchase an equal number of shares, the full exercise of the Warrants
    into 1,210,000 shares at $7 per share of Old ZMAX Common Stock and assumes
    that the fair market value of the Company's Common Stock on the date of
    the Exchange is $14.375 (the closing price on June 18, 1997 as quoted on
    the OTC Bulletin Board). Pro Forma also assumes that the Merger has been
    consummated and that no Old ZMAX stockholders exercise their dissenters'
    rights. See "The Merger--Dissenters' Rights."
 
(C) Pro forma as adjusted represents issuances of Old ZMAX Common Stock since
    March 31, 1997 (see "Management's Discussion and Analysis of Financial
    Condition and Results of Operations--Recent Developments"), including (i)
    1,600,000 shares issued in April 1997 upon the conversion of the Company's
    convertible notes, (ii) 670,000 shares issued in April 1997 in connection
    with the CSI transaction, (iii) 234,365 shares issued in April 1997 in
    connection with the Company's purchase of Fiserv's interest in the Fiserv
    Century Services Joint Venture, (iv) 32,077 shares issued in May 1997 as
    satisfaction for a promissory note, (v) 150,000 shares issuable in
    connection with the Company's acquisition of the COCACT software, and (vi)
    60,000 shares issuable to a consultant for services rendered. For shares
    not issued as of June 18, 1997, the closing price of $14.375 on June 18,
    1997 is assumed to be the fair market value of the Company's Common Stock
    on the date of issuance.
 
(D) Excludes (i) 208,126 shares of Common Stock issuable upon exercise of
    options outstanding as of March 31, 1997 with a weighted average exercise
    price of $11.00, (ii) 1,200,000 shares issuable upon exercise of options
    granted at $14.31 in April 1997 under the 1997 Stock Incentive Plan of
    which options to purchase 100,000 of such shares are currently
    exercisable, (iii) 36,000 shares issuable upon exercise of options granted
    at $14.06 in May 1997 under the 1997 Directors Formula Stock Option Plan
    of which options to purchase 24,000 of such shares are currently
    exercisable, (iv) 500,000 shares of Common Stock reserved for issuance to
    executives under the Company's bonus program or upon exercise of options
    that may be granted under the 1997 Stock Incentive Plan, (v) 84,000 shares
    of Common Stock reserved for issuance upon exercise of options that may be
    granted under the 1997 Directors Formula Stock Option Plan, and (vi)
    12,000 shares issuable upon exercise of options that will be granted to a
    director nominee upon such nominees taking office of which options for
    8,000 of such shares will be immediately exercisable.
 
(E) Gives effect to the Merger. The authorized capital stock of the Old ZMAX
    consists of 95,000,000 shares of Old ZMAX Common Stock and 10,000,000
    shares of preferred stock, of which 5,000,000 shares have been designated
    as Series A Preferred Shares. Upon completion of the Merger, the
    authorized capital stock of New ZMAX, the surviving corporation of the
    Merger, will consist of 50,000,000 shares of Common Stock and 10,000,000
    shares of Preferred Stock.
 
(F) Represents 904,365 shares issuable as of March 31, 1997 pursuant to
    agreements existing at March 31, 1997 related to the CSI transaction and
    the purchase of Fiserv's interest in the Fiserv Century Services Joint
    Venture. See "Notes to Consolidated Financial Statements."

  On June 18, 1997, the last reported bid price of Old ZMAX Common Stock
quoted on the OTC Bulletin Board was $14.25 per share. The foregoing
quotations reflect inter-dealer prices, without retail mark-up, markdown or
commission and may not represent actual transactions. The U.S. trading market
for the Old ZMAX Common Stock has been limited and characterized by
significant price and volume volatility. Old ZMAX has not been subject to the
periodic reporting requirements of the Exchange Act and accordingly current
public information regarding Old ZMAX and its business has not been widely
disseminated by Old ZMAX. As a result of the foregoing, historical price
quotations for the Old ZMAX Common Stock may not be indicative of the
operations, financial conditions or prospects for the Company as evidenced by
Old ZMAX's issuance of Common Stock and Common Stock equivalents in the fall
of 1996 at prices less than the quoted market price at such time. As of July
 , 1997, the Company believes there were approximately 124 record owners of
the Company's Common Stock, including shares held by banks, brokers and
depository companies who hold as nominees for numerous beneficial owners.
 
  The Company has not paid any cash dividends on its Common Stock in the past
and does not expect to pay cash dividends in the foreseeable future. The
Company currently intends to retain any future earnings to finance the
development and operation of its business. The Company's future dividend
policy will be determined by the Board of Directors and will depend upon,
among other factors, the Company's earnings, financial condition, capital
requirements, the impact of the distribution of any dividends on the Company's
financial condition and tax liabilities and such other conditions as the Board
of Directors may deem relevant.

                            SELECTED FINANCIAL DATA
 
  The tables below present selected historical financial data of Old ZMAX. The
Old ZMAX historical data for the period from December 13, 1995 (Date of
Inception) to December 31, 1995 and for the year ended December 31, 1996, are
based on the historical financial statements of ZMAX Corporation as audited by
Arthur Andersen LLP, independent public accountants. On November 6, 1996, Old
ZMAX, a shell company listed on the OTC Bulletin Board, acquired 100% of the
outstanding common stock of Century Services, Inc. ("CSI"), a Maryland
corporation. CSI was a privately held company formed on December 13, 1995 to
perform computer re-engineering with a focus on providing a solution to the
Year 2000 problem. For financial reporting purposes, the acquisition has been
treated as a recapitalization of CSI with CSI as the acquirer (a reverse
acquisition). The historical financial statements prior to November 6, 1996
are those of CSI. The accompanying consolidated financial statements include
all of the accounts of CSI and the accounts of Old ZMAX for the period from
the acquisition on November 6, 1996, through December 31, 1996. The selected
financial data for Old ZMAX for the three-month periods ended March 31, 1996

                    MANAGEMENT'S DISCUSSION AND ANALYSIS 
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
PRELIMINARY NOTE REGARDING FORWARD LOOKING STATEMENTS
 
  The information set forth in "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and in "Risk Factors" and
"Business" includes "forward-looking statements" within the meaning of Section
27A of the Securities Act and Section 21E of the Exchange Act. Factors that
could cause results to differ materially from those projected in the forward-
looking statements are set forth in "Management's Discussion and Analysis of
Financial Condition and Results of Operations" below and in "Risk Factors."
 
OVERVIEW
 
  On November 6, 1996, Old ZMAX, a shell company listed on the OTC Bulletin
Board incorporated in Nevada, acquired all of the outstanding stock of CSI.
Prior to this transaction, Old ZMAX had no operations and its activities
consisted of efforts to establish or acquire a new business and to raise
capital. CSI was a privately held company formed on December 13, 1995. For
financial reporting purposes, the acquisition has been treated as a
recapitalization of CSI with CSI as the acquirer (a reverse acquisition). The
historical financial statements prior to November 6, 1996 are those of CSI.
 
  CSI markets millennium services to a variety of commercial and government
organizations. See "Business." In the next 12 months, the Company intends to
make additional investments in the further development and marketing of CSI's
millennium services and other software re-engineering services. In addition,
the Company currently intends to pursue acquisitions in the information
technology industry that will complement CSI.
 
  In view of the development costs relating to CSI's millennium services, the
Company believes the period-to-period comparisons of its financial results are
not necessarily meaningful and should not be relied upon as an indication of
future performance. Specifically, as CSI increases its workforce in order to
meet future demand for its millennium services, it will incur training, salary
and other costs prior to the recognition of related revenues. In addition,
most of CSI's revenues are expected to be derived from a relatively small
number of large-scale, comprehensive millennium conversion projects provided
by CSI and its strategic partners. Consequently, CSI's revenues and operating
results are expected to be subject to substantial variations in any given year
and from quarter to quarter. See "Risk Factors--Uncertain and Undeveloped
Market for Millennium Services."
 
  The Company believes some demand for CSI's millennium services may continue
to exist for some time after the year 2000, although this demand will diminish
significantly over time and will eventually disappear. However, the Company's
proprietary tools may be used in conversion projects unrelated to Year 2000
compliance. The Company plans to pursue businesses and business opportunities
unrelated to the millennium problem in the information services market and to
develop products and services to take advantage of these opportunities, such
as migrating a client's software application from a mainframe to a client-
server environment. However, there can be no assurance that the Company will
be able to successfully expand its business beyond the millennium conversion
market. The failure to diversify and develop additional products and services
could materially and adversely affect the Company's business, operating
results and financial condition. See "Risk Factors--Need to Develop Additional
Products and Services."
 
  Most of the Company's current cost structure is fixed. Expenses consist
primarily of the salaries and benefits paid to the Company's technical,
marketing and administrative personnel and benefits, travel, promotions and
trade show expenses, office expenses and other general overhead costs.
Amortization and depreciation expense relates to property and equipment and
intangibles assets. As a result of its plan to expand its operations and to
offer a wider range of information services, the Company expects these costs
to increase.
 
                                      32
<PAGE>
 
  Margins for the Company's millennium services business will depend upon
volume of service because a significant portion of the Company's cost
structure is fixed. Most of the Company's millennium conversion projects are
expected to be priced on a fixed fee basis. Therefore, the profitability of an
individual project will depend upon completing the project within the
estimated number of staff hours and within the agreed time frame.
 
CSI RECAPITALIZATION
 
  Old ZMAX purchased all of the outstanding shares of CSI stock pursuant to a
stock purchase agreement between the CSI shareholders and Old ZMAX dated
November 6, 1996 (the "Stock Purchase Agreement"). The combination of CSI and
Old ZMAX has been accounted for as a recapitalization of CSI, a reverse
acquisition in which CSI, a private operating company acquired ZMAX, a shell
company listed on the OTC Bulletin Board. The former CSI stockholders (the
"Former CSI Stockholders") effectively entered into an agreement with the
transaction promoters to raise debt and equity capital through offshore
placements using ZMAX as the vehicle. As part of that process, the interest of
Fiserv in the Year 2000 business (through its joint venture interest) was
reacquired (as described below) and a stock performance compensation plan was
put in place for the Former CSI Stockholders who continued as employees of CSI
(as described below).
 
  At the closing on November 6, 1996, Old ZMAX issued 3,200,000 shares of Old
ZMAX Common Stock in the name of the Former CSI Stockholders, of which 400,000
shares were delivered to the Former CSI Stockholders. The remaining 2,800,000
shares (the "Escrowed Stock") were placed in escrow subject to quarterly
release based on the cash flows generated by CSI. One share of Escrowed Stock
will be released from escrow for each $1.25 of cash flow generated. The Former
CSI Stockholders are entitled to vote the Escrowed Stock and to receive their
respective pro rata share of any distributions or dividends on the Escrowed
Stock. The Escrowed Stock is subject to forfeiture if the Former CSI
Stockholder's employment agreement with CSI is terminated for cause or if the
Former CSI Stockholder breaches any non-compete or other restrictive covenant
with CSI. As of June 18, 1997, no Escrowed Stock had been released from
escrow.
 
  In connection with the CSI transaction, the Former CSI Stockholders entered
into a stockholders' agreement with the Company dated November 6, 1996 (as
amended, the "Stockholders Agreement"). Under the Stockholders Agreement, the
Former CSI Stockholders may not sell, pledge, encumber, give, bequeath, or
otherwise transfer or dispose of their Old ZMAX stock without complying with
the terms of the agreement or obtaining the prior written consent of the
Company. A Former CSI Stockholder who receives a qualified offer (as defined
in the agreement) must notify the Company of the offer and the Company has an
option to elect to purchase the stock under the terms contained in the
qualified offer. The Former CSI Stockholders are not required to comply with
the provisions described above in order to effect a sale or disposition of
their stock made in compliance with SEC Rule 144 under the Securities Act.
 
  At the time of the CSI recapitalization, the Former CSI Stockholders were
also employed by the Company under employment agreements with CSI. If the
employment of the Former CSI Stockholder is terminated for cause (as defined
in the employment agreement) or if following the termination of the employment
agreement, the Former CSI Stockholder is determined to have breached any non-
competition covenants or other restrictions in his employment agreement, the
Company will have an option to elect to purchase the stock at its current
value (as defined in the Stockholders Agreement). If the employment of the
Former CSI Stockholder is terminated for a reason other than for cause,
excluding expiration of the employment agreement by its terms, or if the
employee becomes permanently disabled, the stockholder will offer its stock
for sale to the Company at a price designated by the offering Former CSI
Stockholder and the Company will have an option to elect to purchase the stock
at the offer price or, if the Former CSI Stockholder fails to designate a
price, the current value price (as defined in the Stockholders Agreement).
 
  In the event that a Former CSI Stockholder dies, the Company will have the
option to purchase and the Former CSI Stockholder's estate will be required to
sell all of the stock at the current value price (as defined in
 
                                      33
<PAGE>
 
the Stockholders Agreement). Any Escrowed Stock subsequently received by a
Former CSI Stockholder's estate will be subject to this provision at the time
of earn out.
 
  Under the terms of the Stockholders Agreement, the stock may only be offered
for sale, sold or transferred pursuant to an effective registration under the
Securities Act or an exemption therefrom. The transfer restrictions, and
purchase options granted in the Stockholders Agreement last for a term of
three years from the date of the agreement and will expire on November 6,
1999. The restrictions apply to any additional shares of Old ZMAX stock
acquired after the execution of the Stockholders Agreement. There are
currently 3,200,000 shares of Old ZMAX Common Stock subject to the
Stockholders Agreement.
 
  In the Stock Purchase Agreement, the Former CSI Stockholders agreed to
indemnify the Company for breaches of the representations and warranties made
to the Company in that agreement. In order to secure their indemnification
obligations, each Former CSI Stockholder pledged the shares of Old ZMAX Common
Stock, including the Escrowed Stock, received by him in the CSI transaction
Acquisition in favor of the Company pursuant to a stock pledge and security
agreement dated November 6, 1996 (the "Stock Pledge Agreement"). In the event
the Company incurs losses as a result of a breach of a representation or
warranty made by the Former CSI Stockholders, the Company is authorized to
transfer, cancel or liquidate the Old ZMAX Common Stock registered in the name
of the Former CSI Stockholders to offset its losses. The term of the Stock
Pledge Agreements expires on August 6, 1997, at which time the certificates
representing the Escrowed Stock will continue to be held in escrow subject to
earn out as described above.
 
  As part of the CSI recapitalization, Old ZMAX acquired the interests of
Fiserv, Inc. in the Fiserv Century Services Joint Venture. See "The Company."
As part of this joint venture acquisition, Old ZMAX agreed to issue to Fiserv
3% of the shares of Old ZMAX outstanding on the closing date of the CSI
recapitalization, or 234,365 shares, and to allow Fiserv to appoint a member
to the Old ZMAX Board of Directors. The issuance of these shares to Fiserv was
completed in April 1997.
 
  With funding from the Company, CSI is now implementing its business plan and
marketing campaign. See "Business." In the next 12 months, the Company intends
to make additional investments in the further development and marketing of
CSI's millennium services as well as investigating related acquisitions in the
information technology industry that will complement CSI.
 
RECENT DEVELOPMENTS
 
 Conversion of $2.1 million Notes.  From September 1996 to November 1996, the
Company issued a total of $2.1 million in convertible notes that were due in
January and March of 1997. The notes were convertible, at the option of the
holder, into a total of 1,600,000 shares of the Company's common stock. Of the
total, $600,000 of the notes were convertible at a rate of one share per $1.00
of principal. The remaining $1,500,000 were convertible at a rate of one share
per $1.50 of principal. All holders of the convertible notes notified the
Company of the exercise of their conversion rights in early 1997, prior to the
due dates of the notes. In March 1997, the Board of Directors approved the
conversion and, in April 1997, all $2.1 million of convertible notes were
converted into an aggregate 1,600,000 shares of Old ZMAX Common Stock.
 
 Issuance of Finders Fee Shares. In connection with the CSI transaction and
related financing, Old ZMAX agreed to issue 320,000 shares of Old ZMAX Common
Stock to Shafiq Nazerali as a fee for his services. At the direction of Mr.
Nazerali, these shares were issued to Valorinvest Ltd. in April 1997. Old ZMAX
also agreed to grant 350,000 shares of Old ZMAX Common Stock to the original
finder of the CSI transaction for $0.30 per share in order to acquire such
finder's rights to the transaction. These shares were issued and the
consideration received in May, 1997.
 
 Conversion of Fiserv Debt.  As part of the CSI recapitalization, the Company
acquired the interest of Fiserv, Inc. in the Fiserv Century Services Joint
Venture in exchange for, among other consideration, Old ZMAX's promissory note
for $385,000. This promissory note has been converted into 32,077 shares of
Old ZMAX Common Stock issued to Fiserv, Inc. in May 1997.
 
                                      34

  Acquisition of COCACT Software. On April 30, 1997, Old ZMAX entered into an
agreement with Taiwan's Institute for Information Industry to purchase all
right, title and interest to the Change of Century Analysis and Conversion
Tool (COCACT) software program, an integral part of CSI's VISION 2000(SM)
solution. Conditions of the purchase agreement included a three month software
development and enhancement project to bring COCACT to the required level of
performance. The purchase price for the COCACT software is $1.1 million in
cash plus 150,000 shares of Old ZMAX Common Stock issuable upon completion and
testing of certain COCACT enhancements to be performed by the seller. The
first installment of the purchase price in the amount of $250,000 was paid in
May 1997, and future installments, as well as the issuance of the shares, will
be made after the software development and enhancement project is completed
and tested.
 
RESULTS OF OPERATIONS
 
  Prior to the CSI transaction, Old ZMAX was a development stage company whose
purpose was to create a vehicle to obtain capital and to seek out,
investigate, and acquire interests in products, properties and businesses that
may have potential for profit. From the date of its inception (April 24, 1986)
through December 31, 1995, Old ZMAX had incurred a cumulative loss of $1.7
million. As of December 31, 1995, Old ZMAX had no assets and liabilities of
$1.4 million.
 
  For financial reporting purposes, the CSI transaction has been treated as a
recapitalization of CSI with CSI as the acquirer (a reverse acquisition). The
historical financial statements including the results of operations prior to
November 6, 1996 are those of CSI.
 
  CSI is a development stage company that was formed on December 13, 1995. Its
1995 activities were limited to acquiring the rights to two of its software
tools. In 1996, the Company incurred a loss of $11.5 million or $13.45 per
share. No revenues were generated in 1996. Included in the 1996 loss were
several significant non-cash charges including approximately $2.9 million of
expense related to the CSI transaction, approximately $7.0 million in interest
charges related to the amortization of the discount on the Company's
convertible debt that resulted from an allocation of the proceeds of the debt
to additional paid-in capital to reflect the beneficial conversion feature on
the convertible debt, approximately $380,000 in amortization of intangibles
and deferred financing costs, and approximately $300,000 in non-employee stock
compensation expense. The remaining expenses are primarily attributable to the
salaries and benefits paid to the Company's technical, marketing and
administrative personnel along with other marketing and administrative
expenses.
 
  Results for the three months ended March 31, 1996, were a loss of $46,814 or
$0.12 per share. The loss was primarily related to the commencement of
operations by CSI in early 1996. Results for the three months ended March 31,
1997, were a loss of $1.3 million or $0.63 per share. No revenues were
generated in either quarter. Included in the 1997 loss were several
significant non-cash charges. Approximately $590,000 in interest charges were
recorded related to the amortization of the discount on the Company's $2.1
million convertible notes that resulted from an allocation of the proceeds of
the debt to additional paid-in capital to reflect the beneficial conversion
feature on the debt. Approximately $297,000 in amortization of intangibles and
deferred financing costs was recorded. Approximately $300,000 in non-employee
stock compensation was charged to expense. The remaining loss reflects the
costs related to the increased operations of CSI and fees and expenses
associated with the preparation of documents in connection with the Merger,
the Exchange Offer and the transactions contemplated thereby. Current assets
totaled $3.7 million, a decrease of $1.2 million from December 31, 1996,
attributable to a decrease in cash that was used for operations and for the
purchase of property and equipment and payment on the Company's long-term
obligation related to its purchase of the COCACT software tool.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  As part of the recapitalization of CSI, Old ZMAX, prior to the CSI
transaction, sold 2,800,000 shares of Common Stock for $0.30 per share or
$840,000 in the aggregate. The proceeds were used to satisfy outstanding
liabilities of Old ZMAX. Also as part of the recapitalization of CSI, Old
ZMAX, prior to the recapitalization issued $1.5 million of convertible notes
for cash. A portion of the proceeds was used to satisfy outstanding
 
                                      35
<PAGE>
 
liabilities of Old ZMAX. In addition, prior to the CSI transaction, Old ZMAX
issued a $480,000 convertible note as satisfaction for certain liabilities of
Old ZMAX. Subsequent to the CSI transaction, the Company issued an additional
$120,000 in convertible notes for cash. In early 1997, the holders of the
convertible notes exercised their conversion rights and the $2.1 million in
aggregate convertible notes were converted into a total of 1,600,000 shares of
Common Stock. In December 1996, the Company issued $5.5 million in convertible
exchangeable subordinated debentures for cash. As of December 31, 1996 and
March 31, 1997, the Company had approximately $4.9 million and $3.7 million in
cash, respectively, and $2.7 million and $1.0 million of working capital,
respectively.
 
  The nature of the information technology industry, combined with the rapidly
growing demand for Year 2000 services worldwide, makes it difficult for the
Company to predict future liquidity requirements with certainty. However, the
Company believes that existing cash, together with the proceeds from the
exercise of the Warrants (see "The Exchange Offer"), will be adequate to
finance continuing operations, investments in property and equipment, and
expenditure for the development of additional software improvements in the
Company's VISION 2000(SM) toolset.
 
  Over the longer term, the Company must successfully execute its plans to
generate significant positive cash flows if it is to sustain adequate
liquidity without impairing growth or requiring the infusion of additional
funds from external sources of cash. See "Business." Additionally, a major
expansion, such as would occur with the acquisition of a major new subsidiary
might also require external financing that could include additional debt or
equity capital.

INTRODUCTION
 
  The Company focuses on acquiring, building and operating companies in the
information technology industry. In 1996, the Company acquired all of the
stock of CSI. See "The Company." CSI intends to provide re-engineering and
information processing services to users of large-scale computer systems in
North America and Europe. CSI specializes in assisting business organizations
and government agencies with what has become popularly known as the "Year 2000
problem." Over the next several years, CSI expects to devote substantial
resources to assisting its clients in preparing for and implementing the
conversion of their computer systems to allow those clients to continue
operations without interruption in the 21st Century.
 
  CSI's management purchased a suite of software tools from Integrated
Microcomputer Systems, Inc., a sixteen year old software re-engineering firm.
Prior to CSI's acquiring rights to these tools, this software suite has been
used in a number of software re-engineering projects. CSI enhanced the tool
suite to specifically address the Year 2000 problem. CSI's total system
solution, known as VISION 2000SM, encompasses a management methodology,
assembly-line processes, and a proprietary automated tool suite to identify
and convert date-sensitive software applications to Year 2000 compliance.
 
  As a small, start-up company, CSI has only limited resources to undertake a
substantial marketing effort. Consequently, CSI's management has endeavored to
form strategic alliances and teaming agreements with major partners who are
interested in providing value-added services to their existing client base. To
date, CSI has entered into alliances with the Institute for Information
Industry (Taiwan), EDS Federal, Hewlett Packard, Hitachi Data Systems, and
First Technology Solutions.
 
THE YEAR 2000 PROBLEM
 
  Throughout most of the history of computer data processing by business and
government, data storage was severely limited both by the design shortcomings
of the storage media themselves and by memory access speed considerations.
Consequently, computer programmers typically encoded years using a two digit
format (e.g., "97" for "1997") rather than a complete, four digit format.
However, the use of a two-digit format makes it impossible to distinguish
between dates in different centuries. Programs required to process a date
after the Year 2000 may interpret the date as 100 years earlier than the
intended date (e.g., 1905 for 2005); may go to an arbitrary default date such
as 1985; or may fail to process the date altogether. Even though a particular
program may have the ability to accommodate a 21st Century date, it may be
unable to communicate that date to other application programs with which it
must interact. As the Year 2000 approaches, a number of these programs have
begun to operate inaccurately, or have failed completely, due to their
inherent inability to properly interpret dates beyond 1999.
 
  Many industry analysts see no precedent to the Year 2000 problem, given our
society's increasing reliance on computing devices and automated
communications networks. Indeed, the very size and complexity of computing
applications makes the Year 2000 problem as much a management issue as a
programming one. Large mainframe applications, 10 to 20 years old, are
referred to as "legacy systems" because they have outlived generations of
programmers. Such systems have patch upon patch of code developed by this
succession of programmers, and limited accurate documentation. In some cases,
the original source code bears little or no resemblance to the object code in
the current production environment or the original code is missing altogether.
This is problematic because source code must match the object production code
before Year 2000 remediation can be effective.
 
  Until recently, many organizations have been able to perform specific tasks
that rely on dates after 1999 by using stand-alone Year 2000 compliant
applications, modifying small amounts of computer code or simply manually
manipulating data. Such solutions are no longer practical as the percentage of
an organization's applications encountering dates after 1999 increases. As the
millennium draws nearer, more and more applications will be at risk.

  Because a single application can potentially corrupt an organization's
entire information network by passing on non-compliant data, resolving the
Year 2000 problem requires individual identification and analysis of all
applications and systems used by the organization. An organization's systems
may include internally developed custom mainframe programs and a large number
of new applications from multiple sources, leading to an absence of standards
among highly integrated and interdependent applications. Changes to
applications may require a corresponding change to the data used by those
applications. Computer hardware and operating systems generally include date-
sensitive programs or processing functions that can be similarly affected.
 
  The Year 2000 problem affects not only data processing functions but also
process control applications. For example, applications such as traffic
regulation, environmental control and factory automation commonly change
programs by date. While these systems are not typically affected by the Year
2000 problem today (as they have no current need to process dates
substantially in the future), as the millennium approaches, many of these
process applications will have to be reprogrammed to allow them to function
after the Year 2000.
 
  The extensive reliance of business firms and government agencies upon
computer-based information systems makes it critical for those organizations
to assess and correct their Year 2000 problem within the next 2 1/2 years.
Many organizations will analyze and modify their existing systems because it
may be very difficult for them to abandon existing systems and replace them
with new Year 2000 compliant systems within the limited time available. And,
besides problems arising in its own systems, an organization may be directly
affected by the date-dependent programs and databases used by outside
organizations. For example, suppliers may have software applications that are
directly integrated with a manufacturer's real-time purchasing application.
With the explosive growth in electronic data interchange (EDI), electronic
funds transfer (EFT) and other forms of electronic commerce, the dimensions of
the Year 2000 problem become compounded.
 
THE MARKET
 
  The Year 2000 problem is particularly important to large organizations with
mainframe computer systems such as banks, securities firms, insurance
companies, healthcare providers, transportation companies, and the full
spectrum of federal, state and city government agencies. Solving the Year 2000
problem is essential in order for these organizations to continue to operate
without interruption into the 21st Century. In some cases, the survivability
of a firm or agency may depend upon its ability to resolve the Year 2000
problem.
 
  An average business mainframe computer may consist of approximately 10
million lines of software code. To manually inventory, analyze, convert, test
and integrate even that modest volume of code would take several years to
complete. The majority of the software code is written in the COBOL language,
which is now considered to be an obsolete language, or in other antiquated
languages such as Assembler. To compound the problem, industry experts have
stated that there are insufficient COBOL programmers and programmers trained
in assembler languages to manually resolve the Year 2000 problem. There are
currently estimated to be only 500,000 COBOL programmers worldwide. Many
programmers trained in COBOL have either retired or have been retrained in
more modern software languages and are reluctant to go back to COBOL
programming for the resolution of the short term Year 2000 problem.
 
  The Gartner Group, a leading information technology consulting company,
estimates that the world-wide cost of resolving the Year 2000 problem is
between $300 billion and $600 billion and that a typical Fortune 500 company
could incur expenses of $50 million to $100 million to resolve its Year 2000
problem.
 
  The Company believes that many organizations will initially attempt to
resolve the Year 2000 problem internally. Others may simply (and expensively)
eliminate and replace programs and equipment. However, the Company believes a
large number of organizations will choose to engage a millennium services
provider to manage some or all of their conversion project. The reasons this
should occur include the substantial increase in technical personnel required
as well as the shortage of programming expertise as noted above. Some industry
analysts including The Gartner Group have suggested that the magnitude of the
Year 2000 problem--and the
 
                                      38
<PAGE>
 
limited time in which to implement a solution--may cause demand for millennium
services to exceed the availability of qualified providers. The market
reaction to the Year 2000 problem has been slow in developing which may result
in the resource demand peaking in late 1998 and 1999. This may lessen the
amount of time the Company will be able to provide its millennium services to
potential clients.
 
STRATEGY
 
  The Company's objectives are: (1) initially to maximize growth in sales of
its millennium services while achieving high profit margins on these sales and
(2) over the long term, to leverage its assets (including its expertise and
client relationships) obtained through providing its millennium services to
develop additional business opportunities in the re-engineering and conversion
industry and related areas. The Company's strategy for achieving these
objectives includes the following key elements:
 
  Achieve Market Penetration Through Strategic Partnerships. To maximize
revenues, the Company is teaming with well-established strategic partners such
as large software developers, system integration companies, and systems
manufacturers. These strategic partners provide broad name recognition, market
position, marketing resources, large project management expertise, and a
large, well-trained work force. By combining the Company's millennium services
with the expertise and resources of its strategic partners, the Company
believes that the teaming arrangements will provide the customer with
superior, comprehensive millennium conversion solutions. Teaming with
strategic partners should also enable the Company to achieve broader market
penetration for its millennium services by capitalizing on the existing client
relationships and ongoing sales and marketing efforts of its strategic
partners in various markets.
 
  Maintain Technological Leadership. The Company intends to conduct research
and development activities in order to improve the functionality, flexibility,
ease of use and cost-effectiveness of its millennium solution. The Company
works closely with its strategic partners and customers to develop new
features and methodologies to meet their requirements. The Company intends to
continue to independently market and deliver a number of comprehensive
millennium conversion solutions to enhance sales revenue, to gather market
information, and to gain the necessary expertise to continually improve its
technology and services.
 
  Distinguish the Company as a Full Service Provider of Millennium
Services. The Company has developed methodologies for analyzing and re-
engineering information systems under a wide variety of scenarios. The Company
intends to market this expertise, which enables the Company to provide the
full range of services typically necessary to manage a client's entire Year
2000 project, including inventory analysis, impact assessment, strategic
planning, conversion, testing and implementation to production. The Company
believes that few Year 2000 solution providers can match the depth, accuracy
and quality of CSI's full service solution.
 
  Penetrate Additional Geographic Markets. Initially, the Company has targeted
the United States market for its millennium services to be followed by
penetration of selected parts of the Western European market. The Company may
pursue opportunities in other geographic areas either directly or through its
strategic alliances, although no specific plans for such expansion have been
developed.
 
  Pursue Additional Business Opportunities. The Company intends to pursue
additional business opportunities in the conversion industry and related areas
utilizing its software tools, experience, and client relationships obtained
while providing millennium services. The Company believes that, while
performing millennium conversions, it will discover new information systems
requirements, such as migrating a client's application from a mainframe
environment to a client server environment or developing enhancements to a
client's existing applications. In turn, the Company will strive to develop
and market new services and software to meet those requirements.
 
MILLENNIUM SERVICES
 
  There are no shortcuts to solving the Year 2000 problem. It requires a
comprehensive and rigorous management approach together with a set of
integrated automated tools. The Company believes that its VISION 2000SM
solution encompasses dependable proprietary tools, methodology and processes
to convert legacy
 
                                      39
<PAGE>
 
software applications to Year 2000 compliance. VISION 2000(SM) consists of two
phases: Phase 1, Global Impact Analysis (GIA), and Phase 2, Conversion and
Implementation (C&I). Each phase is further divided into 3 steps that are
described below.
 
 VISION 2000(SM)--Global Impact Analysis
 
  CSI recognizes that achieving Year 2000 compliance is a management issue
rather than a purely technical issue. Massive software changes must be managed
in a consistent, cohesive and timely manner with minimum cost, interruption
and risk to the organization. CSI's VISION 2000(SM) Global Impact Analysis (GIA)
is designed to provide its clients with detailed and rigorous analysis,
assessment and planning tools. The Company believes that these three elements
are the cornerstones of a successful Year 2000 conversion.
 
  The first step of the GIA phase is the inventory analysis. During this step
the source code of the client's applications systems--including JCL/ECL,
source library, copybook, file definitions, macros, etc.--are gathered for
detailed analysis. The primary functions of the inventory analysis are
designed to validate the completeness of the source code and to define the
domain of the conversion project. CSI uses its proprietary tool, VISION 2000(SM)
Baseline Inventory Control (BIC) to accomplish these functions. BIC is a
robust, mature, menu-driven, Windows 95-based software tool that is designed
to parse source code into component objects and identify all data-flow and
control-flow relationships among systems, subsystems and program modules. BIC
is designed to identify missing or overlapping source modules to be reported
and addressed with the client. BIC also generates statistical reports,
reference reports and application analysis reports. In addition, the results
from its complexity analysis will become one of the input parameters to VISION
2000(SM) Strategic Planner (described below) for schedule and resource planning.
 
  The second step of the GIA phase is the Year 2000 date impact analysis.
VISION 2000(SM) utilizes three levels of naming patterns to identify potential
date data. It uses CSI's extensive library of generic name patterns at the
enterprise level; a project development naming standard (if available) at each
application; and any unique program specific naming conventions at the
program-module level. During the data gathering and candidate field
confirmation processes, CSI collects information about the physical
characteristics and semantic attributes of each primary date candidate. These
candidates become the initial seed from which the VISION 2000(SM) proprietary
algorithm performs global data-flow analysis and computes equivalent classes
of date-related objects. Data-flow analysis is performed at both the program
module level, which identifies all date field data flow propagations, and at
the global level, which identifies all date field usages in subroutine
parameters or global common data objects (e.g., fields, databases). The
evaluation of the data flow analysis is crucial since during the conversion
phase a conversion rule is assigned and executed to affect changes while at
the same time maintaining semantic integrity of the source code. The VISION
2000(SM) Date Analyzer is designed to target the identification of date and
date-related data from the collection of seeds and produces reports that
detail date-impacted information, including the number of date candidates,
date-related occurrences and the density of date-related occurrences within
each programming unit.
 
  The third step of the GIA phase is the development of the strategic plan to
achieve Year 2000 compliance. This includes a series of assessments that
provide conversion alternatives, comprehensive test criteria and
recommendations for each critical decision point. CSI documents each strategic
decision made by the client in a comprehensive strategic plan. During
strategic planning, a date conversion strategy (e.g., expansion, compression
or windowing) must be selected for each subsystem and each major file or
database. Decisions must also be made concerning the conversion of active and
archive files and databases, including when the conversion will take place.
Next, a test strategy must be selected. Testing can only uncover errors but
would never be able to certify the application is error free. Therefore, a
test strategy must be selected to maximize the end user's confidence,
demonstrate conversion quality and balance the cost versus the risk.
 
  All the information gathered during these three steps of the GIA is entered
into the VISION 2000(SM) Strategic Planner to produce a project implementation
plan. This plan details the schedule, resource requirements, conversion
processes, testing processes, responsibilities and costs to execute the Year
2000 implementation plan.
 
                                      40

 VISION 2000(SM)--Conversion and Implementation
 
  The Company believes that its VISION 2000(SM) conversion and implementation
process is an integrated combination of effective, secure and efficient
automated tools and methodologies working in concert designed to produce
consistent, high quality conversion results. The VISION 2000(SM) Y2K Converter
was designed and developed specifically for Year 2000 conversion tasks. The
VISION 2000(SM) Y2K Converter is a rule-based toolset that runs on Windows 95
workstations networked to an NT server. It is designed to convert numerous
platforms of COBOL (IBM, UNISYS, DEC, HP, WANG, etc.) and PL/1 source code. The
Y2K Converter operates in two modes of conversion: global mode and interactive
mode. During global mode conversion, all source components which directly or
indirectly reference a common global date object are modified in unison. The
interactive mode is used when human intervention is required. In the
interactive mode, a programmer browses the color-coded source code and follows
the recommendation provided by the Y2K Converter. Through the use of function
keys, the programmer executes the changes, minimizing or eliminating the
potential for human error in keyboarding. Whenever a line of source code is
modified, VISION 2000(SM) automatically duplicates the original source line,
marks the original as a comment, and modifies the duplicated line. At the same
time, it "audit stamps" the new line with information indicating who performed
the change, what rules were followed, and when the change was executed.
 
  After conversion, the next step is to verify that the converted application
behaves correctly through a series of tests. CSI's testing methodology and
philosophy is to employ, to the maximum extent possible, the test tools, test
cases, and testers already used by the client. CSI test staff and the client's
test personnel together perform the following tests:
 
  . Regression Test: This test is designed to ascertain whether all functions
    of the applications work in the intended manner after the conversion.
 
  . Future Date Test: This test is designed to detect potential errors that
    may exist when the date format is changed to a four-digit format. This is
    similar to the regression test except that the test data are conditioned
    to occur in the future.
 
  . Century Cross Over Date Test: This test is designed to compare
    transactions and records that occur at the end of 1999 and cross over
    into 2000.
 
  . Integration Test: This test is designed to uncover any error that is not
    apparent in each individual component.
 
  Before the successfully tested application is placed back into production,
CSI uses its bridge generator to create temporary or permanent bridges to the
client's application. Bridges are required to provide a transparent and
consistent data view of the modified date fields to the converted application,
as well as to any yet-to-be converted portion of the application software.
 
  VISION 2000(SM) Baseline Inventory Control is designed to define the scope of
a Year 2000 project. VISION 2000(SM) Date Analyzer attempts to identify every
occurrence of date and date-related objects within an application system.
VISION 2000(SM) Date Converter works to apply consistent, rule-based conversion
that minimizes commission errors. The VISION 2000(SM) solution is designed to
produce quality output and thus reduce the testing effort.
 
MARKETING
 
  The Company has initiated a multi-faceted marketing plan to ensure the market
place is aware and knowledgeable of the Company's millennium services.
 
  Internet. The Company maintains a site on the Worldwide Web and is also
listed on the Year 2000 Home Page, which automatically links back to the
Company's web site. Potential clients seeking Year 2000 compliance support can
access the Year 2000 Home Page and obtain information on the Company's
millennium services, VISION 2000(SM), and will be automatically linked to the
Company's web site to obtain more detailed information on VISION 2000(SM).
 
                                       41
<PAGE>
 
  Trade Shows. CSI has co-sponsored Year 2000 conferences and expositions in
concert with the Software Productivity Group in London, Toronto and New York
City. CSI is scheduled to be a co-sponsor at two additional Year 2000
conferences and expositions with the Software Productivity Group during 1997 in
Chicago and San Francisco. These Year 2000 conferences have historically been
sold out with attendees numbering in excess of 500. CSI also participated at
the UNISYS Users Meeting in April, 1997. CSI has found that participating in
Year 2000 trade shows provides a vehicle to reach a large number of potential
clients in a short period of time.
 
  Marketing Communications. The Company has contracts with Michael Baybak and
Company, Inc., a public relations and consulting company to enhance media
recognition of CSI's millennium services, technology and expertise. The Company
believes, the positive name recognition of CSI with Year 2000 compliance will
further enhance its opportunities in the marketplace.
 
  Joint Marketing. The Company will seek joint marketing opportunities with its
alliance partners. The Company believes that the marketing resources of its
alliance partners will add to the exposure and credibility of the Company's
VISION 2000(SM) solution.
 
SALES
 
  Recognizing that the window for contacting and winning clients for Year 2000
services is small and closing with each passing day, the Company has initiated
a very aggressive and multi-faceted sales campaign. Highlights of the Company's
sales campaign are listed below:
 
  Strategic Alliances. CSI has formed strategic alliances with major prime
contractors who are addressing the Year 2000 problem or have a client base in
the market segment. These companies bring a substantial client base, a national
or international distribution system and provide credibility that CSI could not
match by itself. At the present time, CSI has established alliances with EDS
Federal, Hewlett Packard, Hitachi Data Systems and First Technology Solutions.
Although the Company has not yet received any clients through its strategic
partners, the Company believes that as the Year 2000 approaches its strategic
partners will receive demand from their client base for Year 2000 compliance
support and will call on CSI to provide these services.
 
  Direct Marketing. CSI implemented a mail-out campaign to over 300 financial
institutions that will be followed by telephone contacts to determine interest
and potential buyers of millennium services.
 
  Direct Sales. The Company uses a telemarketing approach that cold calls
select markets, i.e., financial institutions, communications companies, UNISYS
users, PL1 systems users, etc., to introduce CSI's millennium services and
arranges a technical briefing for the potential client. The Company's senior
sales and technical personnel conduct the technical briefing. This approach is
designed to maximize the use of CSI's talented employees and shorten the sales
cycle by responding to all the client's technical issues and concerns at the
technical briefing.
 
  Independent Sales Representatives. The Company has recruited independent
sales representatives to sell CSI's VISION 2000(SM) solution. These sales
representatives operate on a sale-of-opportunity basis, utilizing their
existing industry contacts, and are only compensated on successful sales on a
percentage commission basis. These sales representatives pay their own
expenses. The Company also employs sales representative who earn a salary plus
a percentage commission basis.
 
CLIENTS
 
  CSI has successfully performed pilots for several large companies. CSI has
entered into a Year 2000 compliance contract with Bessemer Trust, a financial
and investment adviser that supervises over $14 billion in assets for over 800
clients with offices in 10 cities. CSI has also submitted proposals to provide
its millennium and other software re-engineering services to approximately 15
other companies in telecommunications, utilities, health care, retail,
manufacturing and related industries in addition to state and federal
government agencies. All of these proposals are currently pending.
 
                                       42
<PAGE>
 
COMPETITION
 
  The market for millennium services is highly competitive and will become
increasingly competitive as the Year 2000 approaches. The Company classifies
its existing competitors addressing the Year 2000 problem into three
categories: (1) Product Vendors; (2) Full Service Providers; and (3)
Consultants.
 
  Product Vendors. Companies that have been providing legacy system support
through software tools have made modifications and enhancements to their
existing tools to support Year 2000 services. The majority of the available
tools utilized by product vendors support legacy code analysis for applications
written in COBOL. The Company believes that product vendors will continue to
proliferate and will offer piece-meal solutions to the Year 2000 problem. Most
product vendors will likely concentrate in the assessment of COBOL based
systems and will likely attempt to form strategic alliances with full service
providers and consultants since the majority of clients will look to outsource
the Year 2000 solution. It is also possible that repair product vendors may
even attempt to become full service providers by acquiring proven program
managers and low cost converters. Product vendors that are currently providing
legacy system support for the Year 2000 problem include: ADPAC Corp., Alydaar
Software Corp., ISOGON, Mainware Inc., Quintic Systems, Inc., SEEC, Inc., Trans
Century Data Systems, and Viasoft, Inc.
 
  Full Service Providers. Major companies providing information technology
professional services to their clients, especially data center related services
(such as programmers and software development), are developing tools to provide
analysis and conversion support to their clients with Year 2000 problems.
Although there are a limited number of full service providers, their Year 2000
services afford them an opportunity to penetrate new accounts and leverage
other products and services. The Company believes that several full service
providers have acquired off-shore support to lower their cost. The Company also
believes that existing clients of full service providers will seek assistance
from the established full service provider relationship to resolve their Year
2000 problems. The Company believes that full service providers will remain
limited in number and some will form strategic alliances with product vendors
if the tools offered by product vendors are perceived to be superior in terms
of quality and cost to those developed in-house by the full service providers.
Examples of full service providers are: Cap Gemini America, Computer Horizons,
EDS, IBM ISSC, IBS Conversions, Inc., and Information Management Resources,
Inc.
 
  Consultants. The Company believes that most companies providing information
technology (IT) consulting to their clients will expand their services to
include Year 2000 support. However, the Company believes that most of the
efforts of IT consultants to date have been focused on the up-front segment of
the solution, i.e., assisting clients in determining the size and scope of
their Year 2000 problem and developing a fixed strategy to resolve the Year
2000 problem in concert with their client's long term IT plans. The Company
seeks to establish relationships with IT consultants and thereby work
cooperatively with consultants to resolve their clients' Year 2000 problems
utilizing the Company's services. The Company believes that consultants will
continue to leverage existing high level client relationships into a Year 2000
business. However, the Company also believes that consultants will typically
seek to form strategic alliances with product vendors. Examples of consultants
are Deloitte Touche and James Martin & Co.
 
INTELLECTUAL PROPERTY
 
  The Company's intellectual property primarily consists of the methodologies
developed for use in its millennium services and ownership or exclusive rights
to the use of its software tool suite known as the VISION 2000(SM) solution. The
Company does not have any patents and relies upon a combination of trade
secret, copyright and trademark laws and contractual restrictions to establish
and protect its ownership of its proprietary methodologies and exclusive rights
to use its software tool suite. The Company generally enters into non-
disclosure and confidentiality agreements with its employees, independent sales
agents, and clients. Despite these precautions, it may be possible for an
unauthorized third party to replicate the Company's methodologies or to obtain
and use information that the Company regards as proprietary.
 
                                       43
<PAGE>
 
  As the number of competitors providing millennium services similar to those
offered by the Company increases, it is more likely that substantially similar
tools and methodologies will be used in providing such services. Although the
Company's software products and services have never been the subject of an
infringement claim, there can be no assurance that third parties will not
assert infringement claims against the Company in the future, that the
assertion of such claims will not result in litigation, or that the Company
would prevail in such litigation or be able to obtain a license for the use of
any allegedly infringed intellectual property from a third party on
commercially reasonable terms. Furthermore, litigation, regardless of its
outcome, could result in substantial cost to the Company and divert
management's attention from the Company's operations. Although the Company is
not aware of any basis upon which a third party could assert an infringement
claim, any infringement claim or litigation against the Company could therefore
materially adversely affect the Company's business, operating results, and
financial condition. See "Risk Factors--Risk of Third Party Claims of
Infringement."
 
PERSONNEL
 
  As of June 18, 1997, the Company had 17 full-time employees including 5
persons in Sales, 8 persons in Operations/Engineering and 4 persons in
Management and Administration. The Company also employs temporary employees and
consultants.
 
PROPERTIES
 
  The Company's corporate headquarters are located at 20251 Century Boulevard
in Germantown, Maryland, outside Washington, D.C. The Company currently
occupies approximately 13,000 square feet through a sublease that expires
September 30, 2000. The Company's annual rent for 1997 is $132,912, and is
subject to annual upward adjustment. The Company also pays its pro rata share
of increases to real estate taxes and operating expenses for the property. The
Company anticipates expanding its current facilities to accommodate the
expected continued growth of the Company. The Company believes that it can
obtain the additional facilities required to accommodate its projected needs
without difficulty and at commercially reasonable prices, although no assurance
can be given that it will be able to do so.
 
LEGAL PROCEEDINGS
 
  The Company is not involved in any material legal proceedings except possibly
as described below. On April 17, 1997, Alan L. Levine and Canadian American
Petroleum Corporation filed suit in the Third Judicial District Court of Sale
Lake County, Utah against Old ZMAX, f/k/a Mediterranean Oil Corp., f/k/a Oryx
Gold Corp., f/k/a Pandora, Inc. and John Does. The lawsuit seeks unspecified
consequential and punitive damages arising from the alleged delay in the
issuance of shares of Common Stock of Pandora, Inc. The plaintiffs allege that
they currently own approximately 64,000 shares of stock earned as compensation
for services rendered at various times prior to 1992. The lawsuit is currently
in the investigative stage and the time to answer has not matured. Given the
preliminary stage of this proceeding, the Company has not been able to assess
the relative materiality, or lack thereof, of the plaintiff's claims. The
Company intends to vigorously defend itself in this action.

BOARD OF DIRECTORS AND COMMITTEE MEETINGS
 
  The Board of Directors of the Company held eleven meetings or written
consent actions during 1996. In December 1996, the Board of Directors
established a Compensation Committee. The Compensation Committee reviews and
makes recommendations to the Board of Directors regarding the compensation and
benefits of all the executive officers and consultants of the Company,
administers the Company's compensation and benefit plans, and reviews general
policies relating to compensation and benefits. The members of the
Compensation Committee are Messrs. Komar and Wareham. Mr. Nazerali consults
with the Compensation Committee upon request. The Compensation Committee did
not hold any meetings during 1996. The Company does not have any other Board
Committees. Each director attended at least 75% of the meetings of the Board
of Directors and all written consent actions were signed by all directors
holding office at the time the action was taken.
 
COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
  The Compensation Committee consists entirely of nonemployee directors and
determines the compensation paid to the Chief Executive Officer and the other
executive officers and consultants of the Company. The Compensation Committee
believes that for the Company to be successful long-term and for it to
increase stockholder value it must be able to hire, retain, adequately
compensate and financially motivate talented and ambitious executives. The
Compensation Committee attempts to reward executives for both individual
achievement and overall Company success.
 
  Executive compensation is made up of three components:
 
    Base Salary. An executive's base salary is initially determined by
  considering the executive's level of responsibility, prior experience and
  compensation history. Published salaries of executives in similar positions
  at other companies of comparable size (sales and/or number of employees) is
  also considered in establishing base salary.
 
    Stock Options.  The Company adopted an incentive stock option plan to
  provide stock option awards to certain executives. See "Proposal to Approve
  ZMAX Corporation 1997 Stock Incentive Plan." The Compensation Committee
  believes that the granting of stock options is directly linked to increased
  executive commitment and motivation and to the long-term success of the
  Company. The Compensation Committee awards stock options to certain
  executives. The Compensation Committee intends to use both subjective
  appraisals of the executive's performance and the Company's performance and
  financial success during the previous year to determine option grants.
 
    Bonus. The Company has also implemented an executive bonus program for
  certain of its executives. Such bonuses are based, in part, on the
  Company's financial performance during the previous fiscal year including
  achievement of gross revenue and net income targets. In addition, objective
  individual measures of performance compared to the individual's business
  unit profit performance may be considered. A subjective rating of the
  executive's personal performance may also be considered. Bonuses may be
  paid in cash or Common Stock or a combination of cash and Common Stock.
  Bonuses are typically linked to a percentage of base salary.
 
                                      50
<PAGE>
 
  The Compensation Committee recommended to the Board of Directors and the
Board of Directors approved a compensation package for the Company's Chief
Executive Officer, Mr. Higgins, that includes a $150,000 base salary with
annual increases plus a bonus of up to 100% of the base salary and for its
Senior Vice President--Technology, Mr. Yeh, that includes a $125,000 base
salary with annual increases and a bonus of up to 100% of the base salary.
Receipt of the bonus is subject to the Company's achievement of certain
performance criteria, including gross revenue and net income targets. If the
bonus targets are achieved, the bonus for Mr. Higgins would be paid 25% in
cash and 75% in Common Stock and the bonus for Mr. Yeh would be paid 50% in
cash and 50% in Common Stock. In each case, the number of shares of bonus
stock will be equal to the dollar amount of the bonus payable in stock divided
by the fair market value (as defined) of the Common Stock at the end of the
fiscal year. If the performance criteria are not achieved or the executive is
no longer employed by the Company (other than for cause termination), a bonus
may be awarded in the discretion of the Compensation Committee.
 
  In determining the 1997 compensation packages for these executive officers,
the Compensation Committee considered that Mr. Higgins was a founder of the
Company, the experience and compensation history of each individual and
compensation packages awarded to similar executives of other similarly
situated start-up companies, to the extent such information could be learned.
The Compensation Committee also relied on competitive industry statistics and
other industry comparison data. The Compensation Committee ensured that the
incentive bonus compensation is only paid if the performance targets are met
and the Company is in a sound financial position.
 
  Exceptions to the general principles stated above are made when the
Compensation Committee deems them appropriate to stockholder interest. The
Compensation Committee regularly considers other forms of compensation and
modifications of its present policies, and will make changes as it deems
appropriate The competitive opportunities to which the Company's executives
are exposed frequently come from private companies or divisions of large
companies, for which published compensation data is often unavailable and,
therefore, the Compensation Committee's information about such opportunities
is often anecdotal.
 
  Section 162(m) of the Internal Revenue Code of 1986, as amended, establishes
a limit on the deductibility of annual compensation for certain executive
officers that exceeds $1,000,000 per year unless certain requirements are met.
The Company does not anticipate that any employee will exceed such $1,000,000
cap in the near future but will consider whether any necessary adjustments are
appropriate if it becomes likely that any executive officer's compensation may
exceed the $1,000,000 limit.

1997 DIRECTORS FORMULA STOCK OPTION PLAN
 
  The Company maintains the ZMAX Corporation 1997 Directors Formula Stock
Option Plan (the "Director Plan"). The Board of Directors has reserved 120,000
shares of Common Stock for issuance pursuant to awards may be made under the
Director Plan subject to adjustment as provided therein. The number of shares
of Common Stock associated with any forfeited option are added back to the
number of shares that can be issued under the Director Plan.
 
  The awards under the Director Plan are determined by the express terms of
the Director Plan. The Director Plan will be administered by a committee (the
"Committee"), the members of which are appointed by the Board of Directors.
The Committee will consist of at least one or more members of the Board of
Directors who will not receive a grant of an option under the Director Plan
and who are not currently eligible to receive a grant of an option under the
Director Plan. The Committee members are currently Messrs. Berty and Higgins.
The
 
                                      52
<PAGE>
 
Committee will have the authority in its sole discretion to interpret the
Director Plan and to make all other determinations and to take all other
actions it deems necessary or advisable for the implementation and
administration of the Director Plan.
 
  Other than Mr. Komar and Mr. Wareham, only nonemployee directors of the
Company who do not perform services for the Company are eligible to
participate in the Director Plan. The Director Plan provides for option grants
upon a nonemployee director's initial appointment after May 20, 1997 to the
Board of Directors to purchase 12,000 shares of Common Stock at a price per
share exercise price equal to the then fair market value of a share of Common
Stock. The nonemployee director will vest immediately in 8,000 shares of
Common Stock and will vest in an additional 2,000 shares after the completion
of the first year of continued service and an additional 2,000 shares after
the completion of the second year of continued service. Each option granted
pursuant to the Director Plan will be evidenced by an agreement and will be
subject to additional terms as set forth in the agreement.
 
  Options become exercisable when vested and expire ten years after the date
of grant, subject to such shorter period provided in the agreement.
 
  The Director Plan was effective on May 20, 1997, and will continue to be
effective until ten years after the effective date of the Director Plan,
unless sooner terminated by the Board of Directors.
 
  The number of shares of Common Stock reserved for issuance upon exercise of
options granted under the Director Plan, the number of shares of Common Stock
subject to outstanding options and the exercise price of each option are
subject to adjustment in the event of any recapitalization of the Company or
similar event. The number of shares of stock subject to options granted in
connection with initial appointments or as annual service awards are also
subject to adjustment in such events. In the event of certain corporate
reorganizations and similar events, the options may be adjusted or, with
regard to vested options, cashed out depending upon the nature of the event.
As of the date of this Proxy Statement/Prospectus, 36,000 options have been
granted under the Director Plan and an additional 12,000 options will be
granted to a director nominee upon his taking office with the Company
following the completion of the transactions contemplated by this Proxy
Statement/Prospectus.
 
  A participant will not recognize income upon the grant of an option or at
any time prior to the exercise of the option or a portion thereof. At the time
a participant exercises a nonqualified option or portion thereof, he or she
will recognize compensation taxable as ordinary income in an amount equal to
the excess of the fair market value of the Common Stock on the date the option
is exercised over the price paid for the Common Stock, and the Company will
then be entitled to a corresponding deduction.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
  Pursuant to the Delaware Law, New ZMAX has adopted provisions in its
Certificate of Incorporation that eliminate the personal liability of its
directors to the Company and its stockholders for monetary damages for breach
of the directors' fiduciary duties in certain circumstances and authorize the
Company to indemnify its directors and other agents, by bylaw, agreements or
otherwise, to the full extent permitted by law. The Company's bylaws require
the Company to indemnify its directors to the full extent permitted by law,
including those circumstances in which indemnification would otherwise be
discretionary.

                          PROPOSAL TO ELECT DIRECTORS
 
  The Bylaws of the Company currently provide that the Board of Directors will
determine the number of directors to serve on the Board. The Company's Board
of Directors currently consists of seven members. Each director holds office
until the next Annual Meeting of Stockholders and until his or her successor
is elected and qualified or until his or her earlier resignation or removal.
The Board of Directors has proposed six nominees for directors of Old ZMAX for
vote at the Old ZMAX 1997 Annual Meeting of Stockholders. Other than Edward
Yourdon, each of the six nominees is presently serving as a director of the
Company. If no direction to the contrary is given, all proxies received by the
Board of Directors will be voted "FOR" the election of the six nominees. If
any nominee is unable or declines to serve, the proxy solicited herewith may
be voted for the election of another person in his or her stead at the
discretion of the Board of Directors. The Board of Directors knows of no
reason to anticipate that this will occur. The nominees for directors are:
Michel Berty, Michael C. Higgins, Steve L. Komar, G.W. Norman Wareham, Ted
Fine and Edward Yourdon. Biographical information for all of the nominees is
set forth above in "Directors and Director Nominees."
 
  The Board of Directors of New ZMAX will be classified and the directors will
serve staggered terms as described under "Comparison of Stockholder Rights."
Assuming the nominees set forth above are elected to the Board of Old ZMAX and
the Merger is approved, such persons will become directors of New ZMAX as of
the Effective Time and will be classified as follows:
 
  CLASS I--TERM EXPIRES AT THE 1998 ANNUAL MEETING
    Michael C. Higgins
    G.W. Norman Wareham
 
  CLASS II--TERM EXPIRES AT THE 1999 ANNUAL MEETING

        PROPOSAL TO APPROVE ZMAX CORPORATION 1997 STOCK INCENTIVE PLAN
 
  The Company maintains the ZMAX Corporation 1997 Stock Incentive Plan (the
"Incentive Plan"). The Incentive Plan provides the Company with increased
flexibility to grant equity-based compensation to key employees, officers,
directors and consultants of the Company or an affiliate. The Board of
Directors has reserved 1,700,000 shares of common stock (the "Common Stock")
for issuance pursuant to awards that may be made under the Incentive Plan,
subject to adjustment as provided therein. The number of shares of Common
Stock associated with any forfeited Stock Incentive are added back to the
number of shares that can be issued under the Incentive Plan. The closing bid
price per share of Common Stock reported on the OTC Bulletin Board was $14.25
as of June 18, 1997.
 
  The Incentive Plan was adopted by the Board of Directors on May 20, 1997.
The Incentive Plan is subject to approval of the stockholders within 12 months
after adoption of the Incentive Plan. If such approval is not obtained, any
Stock Incentives granted under the Incentive Plan will be void. The Incentive
Plan is being submitted for approval to the stockholders of Old ZMAX at the
Meeting. See "The Meeting."
 
  Awards under the Incentive Plan will be determined by a committee (the
"Committee"), the members of which are selected by the Board of Directors. The
current members of the Committee are Messrs. Wareham and Komar. The Incentive
Plan permits the Committee to make awards of a variety of equity-based
incentives, including stock awards, options to purchase shares of Common
Stock, stock appreciation rights, phantom shares, performance unit
appreciation rights, and dividend equivalent rights (collectively, "Stock
Incentives").
 
                                      54
<PAGE>
 
  The number of shares of Common Stock for which a Stock Incentive is granted
and to whom any Stock Incentive is granted shall be determined by the
Committee, subject to the provisions of the Incentive Plan. Stock Incentives
issuable may be made exercisable or settled at such prices and may be made
forfeitable or terminable under such terms as are established by the
Committee, to the extent not otherwise inconsistent with the terms of the
Incentive Plan. Each Stock Incentive will be evidenced by a Stock Incentive
Agreement or made subject to the terms of a Stock Incentive Program, each
containing terms and restrictions as the Committee may deem appropriate. No
participant, however, may be granted during any one year period rights to
shares of Common Stock under options and stock appreciation rights which, in
the aggregate, exceed 1,700,000 shares of Common Stock.
 
  The Incentive Plan allows for the grant of incentive stock options and non-
qualified stock options. The Committee will determine whether an option is an
incentive stock option or a non-qualified stock option at the time the option
is granted. The exercise price of an option is established by the Committee.
The exercise price of an incentive stock option may not be less than the fair
market value of the Common Stock on the date of the grant (or less than 110%
of the fair market value if the participant controls more than 10% of the
voting power of the Company or a subsidiary). Non-qualified stock options may
be made exercisable at a price equal to, less than or more than the fair
market value of the Common Stock on the date that the option is awarded. The
Committee may permit an option exercise price to be paid in cash or by the
delivery of previously-owned shares of Common Stock, or to be satisfied
through a cashless exercise executed through a broker or by having a number of
shares of Common Stock otherwise issuable at the time of exercise withheld.
 
  The term of an option will be specified in the applicable Stock Incentive
Agreement. The term of an incentive stock option may not exceed ten years from
the date of grant; however, any incentive stock option granted to a
participant who controls more than 10% of the voting power of the Company or a
subsidiary will not be exercisable after the expiration of five years after
the date the option is granted. Subject to any further limitations in a Stock
Incentive Agreement, in the event of a participant's termination of
employment, an incentive stock option will become unexercisable no later than
three months after the date of such termination of employment; provided,
however, that if such termination of employment is due to death or disability,
one year will be substituted for the three-month period.
 
  Stock appreciation rights may be granted separately or in connection with
another Stock Incentive, and the Committee may provide that they are
exercisable at the discretion of the holder or that they will be paid at a
time or times certain or upon the occurrence or non-occurrence of certain
events. Stock appreciation rights may be settled in shares of Common Stock or
in cash, according to terms established by the Committee with respect to any
particular award.
 
  The Committee may grant shares of Common Stock to a participant as stock
awards, subject to such restrictions and conditions, if any, as the Committee
may determine. Dividend equivalent rights, performance units and phantom
shares may be granted in such numbers or units and may be subject to such
conditions or restrictions as the Committee may determine and will be payable
in cash or shares of Common Stock, as the Committee may determine. The
Committee may make cash awards designed to cover tax obligations of employees
that result from the receipt or exercise of a Stock Incentive.
 
  Stock Incentives generally are not transferable or assignable during a
holder's lifetime. However, Stock Incentives may include exercise, conversion
or settlement rights to a holder's estate or personal representative in the
event of the holder's death or disability. At the Committee's discretion,
Stock Incentives that are subject to termination upon termination of
employment may be cancelled, accelerated, paid or continued, subject to the
terms of the applicable Stock Incentive agreement and to the provisions of the
Incentive Plan.
 
  The number of shares of Common Stock reserved for issuance in connection
with the grant or settlement of Stock Incentives or to which a Stock Incentive
is subject, as the case may be, and the exercise price of each option are
subject to adjustment in the event of any recapitalization of the Company. In
the event of certain corporate reorganizations, Stock Incentives may be
substituted, cancelled, accelerated, cashed-out or otherwise
 
                                      55
<PAGE>
 
adjusted by the Committee, provided such adjustment is not inconsistent with
the terms of the Incentive Plan or any agreement reflecting the terms of a
Stock Incentive.
 
  Although the Incentive Plan may be amended by the Board of Directors without
stockholder approval, the Board of Directors also may condition any such
amendment upon stockholder approval if stockholder approval is deemed necessary
or appropriate in consideration of tax, securities or other laws. No such
action by the Board of Directors may adversely affect the rights of a holder of
a Stock Incentive without the holder's consent.
 
  A participant will not recognize income upon the grant of an option or at any
time prior to the exercise of the option or a portion thereof. At the time a
participant exercises a nonqualified option or portion thereof, he or she will
recognize compensation taxable as ordinary income in an amount equal to the
excess of the fair market value of the Common Stock on the date the option is
exercised over the price paid for the Common Stock, and the Company will then
be entitled to a corresponding deduction.
 
  A participant who exercises an incentive stock option will not be taxed at
the time he or she exercises his or her option or a portion thereof. Instead,
he or she will be taxed at the time he or she sells the Common Stock purchased
pursuant to the option. A participant will be taxed on the difference between
the price he or she paid for the stock and the amount for which he or she sells
the stock. If a participant does not sell the stock prior to two years from the
date of grant of the option and one year from the date the stock is issued to
him or her, the gain will be capital gain and the Company will not get a
corresponding deduction. If a participant sells the stock at a gain prior to
that time, the difference between the amount the participant paid for the stock
and the lesser of the fair market value on the date of exercise or the amount
for which the stock is sold will be taxed as ordinary income and the Company
will be entitled to a corresponding deduction. If the stock is sold for an
amount in excess of the fair market value on the date of exercise, the excess
amount is taxed as capital gain. If a participant sells the stock for less than
the amount he or she paid for the stock prior to the one or two year periods
indicated, no amount will be taxed as ordinary income and the loss will be
taxed as a capital loss. Exercise of an incentive stock option may subject a
participant to, or increase a participant's liability for, the alternative
minimum tax.
 
  A participant generally will not recognize income upon the grant of a stock
appreciation right, dividend equivalent right, performance unit appreciation
right or phantom share (an "Equity Incentive"). At the time a participant
receives payment under any Equity Incentive, he or she generally will recognize
compensation taxable as ordinary income in an amount equal to the cash or the
fair market value of the Common Stock received, and the Company will then be
entitled to a corresponding deduction.
 
  A participant will not be taxed upon the grant of a stock award if such award
is not transferrable by the participant or is subject to a "substantial risk of
forfeiture," as defined in the Code. However, when the shares of Common Stock
that are subject to the stock award become transferrable by the participant and
are no longer subject to a substantial risk of forfeiture, a participant will
recognize compensation taxable as ordinary income in an amount equal to the
fair market value of the stock subject to the stock award, less any amount paid
for such stock, and the Company will then be entitled to a corresponding
deduction. However, if a participant so elects at the time of receipt of a
stock award that is subject to a substantial risk of forfeiture, he or she may
include the fair market value of the stock subject to the stock award, less any
amount paid for such stock, in income at the time of grant and the Company also
will be entitled to a corresponding deduction at that time.
 
  As of June 18, 1997, the Company has issued options to purchase 1,200,000
shares of Common Stock under the Incentive Plan to three individuals including
Messrs. Berty, Higgins and Yeh. On April 17, 1997, Messrs. Berty and Higgins
each received options to purchase 450,000 shares at an exercise price of $14.31
per share. So long as the executive is still employed by the Company, options
for 150,000 shares vest annually if the Company achieves targeted gross
revenues of $9,000,000. Vesting is accelerated to up to 225,000 shares annually
for performance above the target level and is reduced for performance below the
target levels. No vesting will occur if gross revenues are less than $7,000,000
in any fiscal year. On April 17, 1997, Mr. Yeh received options to purchase
300,000 shares at an exercise price of $14.31 per share. Options representing
100,000 shares vested
 
                                       56
<PAGE>
 
immediately upon grant with an additional 100,000 shares vesting at the end of
each of fiscal years 1998 and 1999 so long as Mr. Yeh is still employed by the
Company. With respect to all of these options, if the executive dies or is no
longer employed by the Company at the end of any fiscal year, the Compensation
Committee may accelerate the vesting of these options in its discretion,
assuming, in the case of options tied to performance goals, that the
performance goals are met. The term of these options is ten years from the
date of grant, subject to prior forfeiture in certain events pursuant to the
Incentive Plan.
 
  The Old ZMAX Board recommends that Old ZMAX stockholders vote "FOR" approval
and adoption of the Incentive Plan.

                            PRINCIPAL SHAREHOLDERS
 
  The following table sets forth certain historical and pro forma information
as of July  , 1997 with respect to the shares of Common Stock owned (i) by
each of the Company's directors, director nominees and executive officers,
(ii) by all directors, director nominees and officers as a group, and (iii) by
each person known to the Company to own beneficially more than 5% of the
outstanding shares of Old ZMAX Common Stock. The beneficial ownership
reporting requirements of Section 13(d) of the Exchange Act are not yet
applicable to the Company's stockholders because the Old ZMAX Common Stock is
not yet a registered class of equity securities under the Exchange Act. As a
result, there may be other beneficial owners of 5% or more of the outstanding
Old ZMAX Common Stock who hold such shares through nominees and are unknown to
the Company. As of July  , 1997, there were 9,450,514 outstanding shares of
Old ZMAX Common Stock, which is the Company's only class of voting shares, and
24,000 option shares that are exercisable within 60 days. In addition, one of
the Company's director nominees will receive options for 12,000 shares upon
his election to the Board of Directors of which options for 8,000 shares will
be immediately exercisable. See "Description of Securities" and "Shares
Eligible for Future Sale."

             CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS
 
  Mr. Berty and Mr. Berty's wholly owned company MBY, Inc., are consultants to
the Company providing management advice. See "Management and Executive
Compensation--Key Consulting Agreements."
 
  Mr. Nazerali is a consultant to the Company providing advice in connection
with the Company's efforts to raise capital for its operations and on
acquisition opportunities. Mr. Nazerali received $120,000 consulting fees from
the Company for services rendered in 1996 and $155,635 in reimbursement for
his out-of-pocket expenses. See "Management and Executive Compensation--Key
Consulting Agreements." In addition, Mr. Nazerali was instrumental in the CSI
recapitalization and the financing for the working capital needs of the
Company following that transaction, including the offering of the Debentures
completed in December 1996. See "Description of Securities--Debentures." For
his services to the Company in the CSI recapitalization and Debenture
financing, he was awarded 320,000 shares of Common Stock of the Company. These
shares were issued in the name of Mr. Nazerali's designee, Valorinvest Ltd.,
an Irish company owned by Mr. Nazerali's brother. Valorinvest Ltd. received
approximately $563,000 from Old ZMAX in 1996 in connection with the
recapitalization of CSI as satisfaction for amounts owed by Old ZMAX as of
December 31, 1995.
 
  The Company has engaged Wareham Management Ltd., a company owned by Mr.
Wareham, the Vice President and Chief Financial Officer of the Company, to
provide accounting, bookkeeping and related services under a consulting
agreement. In 1996, Wareham Management Ltd. received approximately $12,235
from the Company for services rendered and $3,016 in reimbursement for his
out-of-pocket expenses. See "Management and Executive Compensation--Key
Consulting Agreements."
 
  Mr. Heideman, a director of the Company from October 1996 through June 18,
1997, was also a consultant to the Company pursuant to a consulting
arrangement. Mr. Heideman received $28,000 in compensation from the Company
for services rendered in 1996 and $4,800 in reimbursement for his out-of-
pocket expenses. This consulting arrangement was terminated by the Company in
April 1997. In addition, Mr. Heideman, through his company, NewDominion
Capital Group Inc., provided consulting services in connection with the CSI
transaction and received 20,000 shares of Common Stock of the Company as
consideration for such services. These shares were issued in the name of
NewDominion Capital Group Inc. in April 1997.
 
  As part of the recapitalization of CSI, the Company acquired the interest of
Fiserv, Inc. in the Fiserv Century Services Joint Venture in exchange for,
among other consideration, Old ZMAX's promissory note for $385,000. In May
1997, this promissory note was converted into 32,077 shares of Old ZMAX Common
Stock issued to Fiserv, Inc. Mr. Komar is a Group Executive Vice President of
Fiserv, Inc. and a director of the Company.

                         DESCRIPTION OF THE SECURITIES
 
  The authorized capital stock of the Old ZMAX consists of 95,000,000 shares
of Old ZMAX Common Stock and 10,000,000 shares of preferred stock, of which
5,000,000 shares have been designated as Series A Preferred Shares. The
Articles of Incorporation authorize the Company's Board of Directors to direct
the issuance of shares of preferred stock in one or more series from time to
time and to fix the designations, powers, preferences, rights, qualifications,
limitations and restrictions of each series, including without limitation
dividend rates, whether dividends will be cumulative, the relative rights of
priority for payment of dividends, voting rights, terms and conditions of
conversion, terms and conditions of redemption, sinking fund provisions, and
rights upon liquidation.
 
  Upon completion of the Merger, the authorized capital stock of New ZMAX will
consist of 50,000,000 shares of Common Stock and 10,000,000 shares of
preferred stock. The New ZMAX Certificate of Incorporation authorizes the
Company's Board of Directors to direct the issuance of shares of preferred
stock in one or more series from time to time and to fix the designations,
powers, preferences, rights, qualifications, limitations and restrictions of
each series, including without limitation dividend rates, whether dividends
will be cumulative, the relative rights of priority for payment of dividends,
voting rights, terms and conditions of conversion, terms and conditions of
redemption, sinking fund provisions, and rights upon liquidation.
 
COMMON STOCK
 
  As of July  , 1997, there were 9,450,514 shares of Old ZMAX Common Stock
issued and outstanding and 100 shares of New ZMAX Common Stock issued and
outstanding. The holders of Old ZMAX Common Stock and New ZMAX Common Stock
are entitled to one non-cumulative vote for each share held of record on all
matters submitted to a vote of shareholders. Subject to preferences that may
be applicable to outstanding shares of Preferred Stock, if any, the holders of
Old ZMAX Common Stock and New ZMAX Common Stock are entitled to receive
ratably such dividends as may be declared by the Company's Board of Directors
out of funds legally available therefor and are entitled to share ratably in
all of the assets of the Company available for distribution to holders of Old
ZMAX Common Stock and New ZMAX Common Stock upon liquidation, dissolution, or
winding up of the affairs of the Company. Holders of New ZMAX Common Stock
have no preemptive, subscription or conversion rights and there are no
redemption or sinking fund provisions or rights applicable thereto. The shares
of New ZMAX Common Stock issued in the Merger will be fully paid and
nonassessable.
 
COMMON STOCK SUBJECT TO RESERVATION
 
  The Company has reserved 1,820,000 shares of Common Stock for issuance under
its Incentive Plan and Director Plan, including for issuance to executives
under its bonus program. See "Shares Eligible for Future Sale."
 
CANCELLATION OF CERTAIN SHARES
 
  In September 1995, the Company entered into a stock cancellation agreement
with a stockholder in which it was agreed that the shares of Common Stock held
by the stockholder would be cancelled in exchange for the transfer to the
stockholder of certain mining claims held by American Oil, a now abandoned
subsidiary of the Company. Due to lack of documentation and proper signature
guarantees, 167,301 of the shares subject to cancellation remain outstanding,
which shares have also been reported lost by the stockholder. Assuming the
stockholder will provide necessary documentation, these lost certificates may
be cancelled of record upon the Company's agreement to indemnify the transfer
agent and the reservation of an equal number shares against the possible
presentation of a lost certificate by a bona fide holder. In the event of
presentation of a lost certificate for transfer, the shares would be
transferred to the presenting bona fide holder from the shares reserved for
this purpose. In such event, the Company may pursue indemnification remedies
against the former stockholder under a lost stock indemnity agreement signed
by the former stockholder in October 1996.
 
                                      61
<PAGE>
 
  In September 1995, the Company also entered into a stock cancellation
agreement with another stockholder in which it was agreed that the shares held
by the stockholder would be cancelled. Due to the shares being lost and the
lack of proper documentation, the Company has been unable to cancel these
shares of record. The Company's attempts to locate the stockholder to correct
document deficiencies have been unsuccessful and the Company currently has
decided to abandon its efforts to do so. The Company is currently considering
obtaining a court order to cancel these shares of record.
 
TRANSFER AGENT AND REGISTRAR
 
  The transfer agent and registrar for the Company's Common Stock is American
Securities Transfer and Trust, Inc., 1825 Lawrence Street, Suite 444, Denver,
Colorado 80202. Its telephone number is (303) 234-5300.
 
PREFERRED STOCK
 
  As of June 18, 1997, there were no shares of Old ZMAX preferred stock issued
and outstanding. If issued, holders of Series A Preferred would be entitled to
convert each share of Series A Preferred into four shares of Common Stock of
the Company at any time at the option of the holder. In all other respects,
the voting powers, preferences, limitations, restrictions and relative rights
of the Series A Preferred are the same as those of the Common Stock.
 
  None of the authorized preferred stock of New ZMAX is issued, outstanding or
designated as to class or series. The Board of Directors, without shareholder
approval, may issue preferred stock with voting and conversion rights that
could materially and adversely affect the voting power of the holders of
Common Stock. The issuance of preferred stock could also decrease the amount
of earnings and assets available for distribution to holders of Common Stock.
In addition, the issuance of preferred stock may have the effect of delaying,
deferring or preventing a change in control of the Company. At present, the
Company has no plans to issue any shares of preferred stock.
 
DEBENTURES
 
  On December 6, 1996, Old ZMAX issued Debentures to 22 non-U.S., accredited
investor subscribers in the aggregate principal amount of $5,500,000. The term
of the Debentures is three years, with a maturity date of December 6, 1999.
The Debentures bear interest at the simple rate of 8% paid semiannually,
commencing on June 1, 1997.
 
  The Company may redeem or prepay the Debentures in full or in part at any
time upon ten days' prior written notice to the holder without penalty or
premium or payment of unearned interest, provided that prior to such
redemption the Company has satisfied the following two conditions: (1) the
Company has made an offer to exchange the Debenture for shares of Common Stock
and Warrants on the terms described below; and (2) the Company has prepared,
filed and caused to be declared effective by the SEC a registration statement
pursuant to the Securities Act regarding such exchange offer. If the exchange
offer is made within six months of the date of issuance of the Debenture
(i.e., June 6, 1997), the terms of the exchange offer for each $1,000
principal amount of the Debenture are (i) 200 shares of Common Stock plus (ii)
one Warrant (a "Warrant") to purchase 200 shares of Common Stock. If the
exchange offer is made after the six-month anniversary of the Debenture, each
$1,000 principal amount of the Debenture may be exchanged for (i) 220 shares
of Common Stock plus (ii) one Warrant to purchase 220 shares of Common Stock.
 
  Prior to the maturity date and prior to redemption by the Company, each
holder of a Debenture has the right to convert all, but not less than all, of
the principal balance of the Debenture into Common Stock of the Company at the
rate of one share for each $5 of the principal amount of the Debenture, in
complete satisfaction of all amounts due and payable under the Debenture.
 
 
                                      62
<PAGE>
 
  The Debentures are non-negotiable and non-transferable.
 
  Debentures not exchanged in the Exchange Offer will become the obligation of
New ZMAX after the Effective Time of the Merger. The Company presently plans
to redeem for cash any Debentures remaining outstanding after completion of
the Exchange Offer at 100% of the principal amount plus interest accrued to
the date of redemption. See "The Exchange Offer."
 
WARRANTS
 
  Warrants issued in the Exchange Offer ("Warrants") may be exercised at the
price of $7 per share if exercised prior to the first year after issuance of
the Warrant, and at the price of $8 per share if exercised during the period
between the first anniversary and the second anniversary of the date of
issuance of the Warrant. The Warrants expire on the second anniversary of the
date of issuance. The Warrants contain adjustment clauses for events such as
reorganization, consolidation, or merger of the Company, reclassification, and
payment of dividends. Each Warrant is transferable in whole or in part upon
the prior written consent of the Company. Warrants that are not exercised
prior to the Merger will become the obligation of New ZMAX after the Effective
Time of the Merger.

<PAGE>
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Future sales of substantial amounts of Common Stock in the public market
could adversely affect prevailing market prices. Upon completion of the
Exchange Offer, the Merger and assuming the Warrants issued in the Exchange
Offer are exercised prior to the Effective Time of the Merger, 11,870,514
shares of New ZMAX Common Stock will be outstanding, including 150,000 shares
of Common Stock Old ZMAX has agreed to issue in connection with the
acquisition of the COCACT software. See "Management's Discussion and Analysis
of Financial Condition and Results of Operation--Recent Developments." The
Company believes that all of these will be freely transferable without
restriction under the Securities Act, except for any shares held by or for the
account of an "affiliate" of the Company, as that term is defined in Rule 144
promulgated under the Securities Act, or by an individual or entity subject to
a contractual restriction on resale.
 
  In general, assuming certain public information regarding the Company is
available, Rule 144 permits a person (or persons whose shares are aggregated)
who has beneficially owned restricted securities within the meaning of Rule
144 ("Restricted Securities") for at least one year is entitled to sell within
any three-month period a number of shares that does not exceed the greater of:
(1) 1% of the then outstanding shares of the Company's Common Stock; or (ii)
the average weekly trading volume of the Company's Common Stock in the
applicable market during the four calendar weeks preceding the date of the
order to execute the transaction. Sales under Rule 144 are also subject to
certain manner of sale provisions, notice requirements and the availability of
current public information about the Company. Any person (or persons whose
shares are aggregated) who is not deemed to have been an affiliate of the
Company at any time during the 90 days preceding a sale, and who owns
Restricted Securities that were purchased from the Company (or any affiliate)
at least two years previously, is entitled to sell such shares under Rule
144(k) without regard to the volume limitations, manner of sale provisions,
public information requirements or notice requirements.
 
  Approximately 1,820,000 shares of New ZMAX Common Stock will be reserved for
issuance to certain executives under its bonus program and upon the exercise
of options under the Company's equity incentive and option plans (the
"Plans"), of which 132,000 will be immediately exercisable following the
Effective Time of the Merger. The Company intends to file a registration
statement on Form S-8 to register the Common Stock reserved for issuance under
the Company's Plans. Shares of Common Stock issued under any of the Plans
after the effective date of a registration statement registering Common Stock
issued or issuable under a Plan, and Common Stock outstanding under such Plan,
will be eligible for resale in the open market, except for shares held by
affiliates and shares subject to any contractual restrictions.
 
STOCKHOLDERS' AGREEMENT
 
  In connection with the Company's purchase of CSI, the former stockholders of
CSI entered into a stockholders' agreement with the Company dated November 6,
1996. This stockholders agreement contains restrictions on transfer and
various buy-sell arrangements between the former CSI stockholders and the
Company. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations--CSI Recapitalization" and "Compensation Committee
Report on Executive Compensation."

                       COMPARISON OF STOCKHOLDERS RIGHTS
 
  Old ZMAX is incorporated under the laws of the State of Nevada and New ZMAX
will be incorporated under the laws of the State of Delaware. On consummation
of the Merger, the stockholders of Old ZMAX, whose rights currently are
governed by Nevada law and Old ZMAX's Articles of Incorporation and Bylaws
which were created pursuant to Nevada law, will become stockholders of a
Delaware company, New ZMAX, and their rights as stockholders will then be
governed by Delaware law and the New ZMAX Certificate of Incorporation and New
ZMAX Bylaws which were created under Delaware law.
 
  Although the corporate statutes of Nevada and Delaware are substantially
similar, certain differences exist. The most significant differences, in the
judgment of the management of the Company, are summarized below. This summary
is not intended to be complete, and stockholders should refer to the Delaware
General Corporation Law (the "Delaware Law") and the Nevada Business
Corporation Act (the "Nevada Law") to understand how these laws will apply to
New ZMAX and Old ZMAX.
 
CLASSIFIED BOARD OF DIRECTORS
 
  The Delaware Law permits any Delaware corporation to classify its board of
directors into as many as three classes as equally as possible with staggered
terms of office. After initial implementation of a classified board, one class
(consisting of approximately 1/3 of the entire board) will be elected at each
annual meeting of the stockholders to serve for a term of three years or until
their successors are elected and take office. The Nevada Law also permits
corporations to classify boards of directors provided that at least one-fourth
of the total number of directors is elected annually. Old ZMAX does not have a
classified board, but New ZMAX's board will be classified. For example, with
respect to removal of directors, under the Nevada Law, any one or all of the
directors of a corporation may be removed by the holders of not less than two-
thirds of the voting power of a corporation's stock. Nevada does not
distinguish between removal of directors with and without cause. Under the
Delaware Law, unless the certificate of incorporation otherwise provides,
directors of a corporation with a classified board may be removed only for
cause, by the holders of a majority of shares then entitled to vote in an
election of directors. The New ZMAX Certificate of Incorporation does not
provide for the removal of directors without cause and, therefore, New ZMAX
directors may only be removed for cause.
 
CUMULATIVE VOTING
 
  Cumulative voting for directors entitles stockholders to cast a number of
votes that is equal to the number of voting shares held multiplied by the
number of directors to be elected. Stockholders may cast all such votes either
for one nominee or distribute such votes among up to as many candidates as
there are positions to be filled. Cumulative voting may enable a minority
stockholder or group of stockholders to elect at least one representative to
the board of directors where such stockholders would not otherwise be able to
elect any directors.
 
  The Nevada Law permits cumulative voting in the election of directors as
long as certain procedures are followed. A Delaware corporation may provide
for cumulative voting in the corporation's certificate of incorporation. Old
ZMAX opted out of cumulative voting by including an appropriate provision in
its Articles of Incorporation. New ZMAX also will not adopt cumulative voting
because the New ZMAX Certificate of Incorporation will not provide for
cumulative voting in the election of directors.
 
  Since neither Old ZMAX nor New ZMAX utilizes cumulative voting, there will
be no difference in stockholders' rights with respect to this issue.
 
VACANCIES
 
  Under the Delaware Law, subject to the rights, if any, of any series of
preferred stock to elect directors and to fill vacancies on the board of
directors, vacancies on the board of directors will be filled by the
affirmative
 
                                      65
<PAGE>
 
vote of a majority of the remaining directors then in office, even if less
than a quorum. Any director so appointed will hold office for the remainder of
the full term of the class of directors in which the vacancy occurred.
Similarly, the Nevada Law provides that vacancies may be filled by a majority
of the remaining directors, though less than a quorum, unless the articles of
incorporation provide otherwise. In addition, the by-laws of Old ZMAX and New
ZMAX address the issue of director vacancies in the same manner. Therefore,
the change from Nevada law to Delaware law will not alter stockholders' rights
with respect to filling vacancies.
 
INDEMNIFICATION OF OFFICERS AND DIRECTORS AND ADVANCEMENT OF EXPENSES
 
  Delaware and Nevada have substantially identical provisions regarding
indemnification by a corporation of its officers, directors, employees and
agents, except Nevada provides broader indemnification in connection with
stockholder derivative lawsuits. Delaware and Nevada law differ in their
provisions for advancement of expenses incurred by an officer or director in
defending a civil or criminal action, suit or proceeding. The Delaware Law
provides that expenses incurred by an officer or director in defending any
civil, criminal, administrative or investigative action, suit or proceeding
may be paid by the corporation in advance of the final disposition of the
action, suit or proceeding upon receipt of an undertaking by or on behalf of
the director or officer to repay the amount if it is ultimately determined
that he or she is not entitled to be indemnified by the corporation. Thus, a
Delaware corporation has the discretion to decide whether or not to advance
expenses. Under the Nevada Law, the articles of incorporation, bylaws or an
agreement made by the corporation may provide that the corporation must pay
advancements of expenses in advance of the final disposition of the action,
suit or proceedings upon receipt of an undertaking by or on behalf of the
director or officer to repay the amount if it is ultimately determined that he
or she is not entitled to be indemnified by the corporation. Thus, a
corporation may have no discretion to decide whether or not to advance
expenses. There will be no difference in stockholders' rights with respect to
this issue because the Old ZMAX Articles of Incorporation and the New ZMAX
Certificate of Incorporation to be in effect after the Merger each provide for
advancement of expenses.
 
  New ZMAX will be obligated to indemnify a narrower range of people than Old
ZMAX. Whereas the Old ZMAX Articles of Incorporation provide for Old ZMAX to
indemnify directors, officers, employees and some agents, the New ZMAX
Certificate of Incorporation only addresses indemnification of directors. In
this regard, it should be noted that the New ZMAX Board of Directors retains
the discretionary authority to authorize the indemnification of officers,
employees and agents, subject to certain conditions under the Delaware Law.
 
LIMITATION ON PERSONAL LIABILITY OF DIRECTORS
 
  A Delaware corporation is permitted to adopt provisions in its certificate
of incorporation limiting or eliminating the liability of a director to a
company and its stockholders for monetary damages for breach of fiduciary duty
as a director, provided that such liability does not arise from certain
proscribed conduct, including breach of the duty of loyalty, acts or omissions
not in good faith or which involve intentional misconduct or a knowing
violation of law or liability to the corporation based on unlawful dividends
or distributions or improper personal benefit. The New ZMAX Certificate of
Incorporation will limit the liability of directors to the Company to the
fullest extent permitted by law.
 
  While the Nevada Law has a similar provision permitting the adoption of
provisions in the articles of incorporation limiting personal liability, the
Nevada provision differs in two respects. First, the Nevada provisions applies
to both directors and officers. Second, while the Delaware provisions excepts
from limitation on liability of breach of the duty of loyalty, the Nevada
counterpart does not contain this exception. Thus, the Nevada provision
expressly permits a corporation to limit the liability of officers, as well as
directors, and permits limitation of liability arising from a breach of the
duty of loyalty. The Old ZMAX Articles of Incorporation limited the liability
to the Company of directors, officers, employees and agents. Therefore, New
ZMAX will adopt a narrower limitation on liability, and more parties will
remain potentially liable to the Company. The Company, however, may determine
to indemnify such persons in its discretion subject to the conditions of the
Delaware Law.
 
                                      66
<PAGE>
 
DIVIDENDS
 
  The Delaware Law is more restrictive than the Nevada Law with respect to
when dividends may be paid. Under the Delaware Law, unless otherwise provided
in the certificate of incorporation, a corporation may declare dividends, out
of surplus, or if no surplus exists, out of net profits for the fiscal year in
which the dividend is declared and/or the preceding fiscal year (provided that
the amount of capital of the corporation following the declaration and payment
of the dividend is not less than the aggregate amount of the capital
represented by the issued and outstanding stock of all classes having a
preference upon the distribution of assets). In addition, the Delaware Law
provides that a corporation may redeem its shares only out of surplus.
 
  The Nevada Law provides that no distribution (including dividends on, or
redemption or repurchases of, shares of capital stock) may be made if, after
giving effect to such distribution, the corporation would not be able to pay
its debts as they become due in the usual course of business, or the
corporation's total assets would be less than the sum of its total liabilities
plus the amount that would be needed at the time of a liquidation to satisfy
the preferential rights of preferred stockholders.
 
RESTRICTIONS ON BUSINESS COMBINATIONS
 
  Both the Delaware Law and the Nevada Law contain provisions restricting the
ability of a corporation to engage in business combinations with an interested
stockholder. Under the Delaware Law, a corporation is not permitted to engage
in a business combination with any interested stockholder for a three-year
period following the date such stockholder became an interested stockholder,
unless (i) the transaction resulting in a person becoming an interested
stockholder, or the business combination, is approved by the board of
directors of the corporation before the person becomes an interested
stockholder; (ii) the interested stockholder acquires 85% or more of the
outstanding voting stock of the corporation in the same transaction that makes
it an interested stockholder (excluding shares owned by persons who are both
officers and directors of the corporation, and shares held by certain employee
stock ownership plans); or (iii) on or after the date the person becomes an
interested stockholder, the business combination is approved by the
corporation's board of directors and by the holders of at least 66% of the
corporation's outstanding voting stock at an annual or special meeting,
excluding shares owned by the interested stockholder. The Delaware Law defines
"interested stockholder" generally as a person who owns 15% or more of the
outstanding shares of a corporation's voting stock.
 
  The Nevada Law regulates business combinations more stringently. First, an
interested stockholder is defined as a beneficial owner of ten percent (10%)
or more of the voting power. Second, the three-year moratorium can be lifted
only by advance approval by a corporation's board of directors, as opposed to
Delaware's provision that allows interested stockholder combinations at the
time of the transaction with stockholder approval. Finally, after the three-
year period, combinations remain prohibited unless (i) they are approved by
the board of directors, the disinterested stockholders or a majority of the
outstanding voting power not beneficially owned by the interested party, or
(ii) the interested stockholders satisfy certain fair value requirements. As
in Delaware, a Nevada corporation may opt-out of the statute with appropriate
provisions in its articles of incorporation.
 
AMENDMENT TO CERTIFICATE/ARTICLES OF INCORPORATION AND BYLAWS
 
  Both the Delaware Law and the Nevada Law require the approval of the holders
of a majority of all outstanding shares entitled to vote, with each
stockholder being entitled to one vote for each share so held, to approve
proposed amendments to a corporation's certificate/articles of incorporation.
Neither state requires stockholder approval for the board of directors of a
corporation to fix the voting powers, designation, preferences, limitations,
restrictions and rights of a class of stock provided that the corporation's
organizational documents grant such power to its board of directors. The
holders of the outstanding shares of a particular class are entitled to vote
as a class on a proposed amendment if the amendment would alter or change the
power, preferences or special rights of one or more series of any class so as
to affect them adversely. The number of authorized shares of any such class of
stock may be increased or decreased (but not below the number of shares then
outstanding) by the affirmative vote of the holders of a majority of the stock
entitled to vote thereon (without a class vote) if so provided in any
amendment to the articles of incorporation or resolutions creating such class
of stock.
 
                                      67
<PAGE>
 
ACTIONS BY WRITTEN CONSENT OF STOCKHOLDERS
 
  The Nevada Law and the Delaware Law each provide that, unless the charter
provides otherwise, any action required or permitted to be taken at a meeting
of the stockholders may be taken without a meeting if the holders of
outstanding stock having at least the minimum number of votes that would be
necessary to authorize or take such action at a meeting consents to the action
in writing. In addition, the Delaware Law requires the corporation to give
prompt notice of the taking of corporate action without a meeting by less than
unanimous written consent to those stockholders who did not consent in
writing. The Old ZMAX Articles of Incorporation did not limit stockholder
action by written consent, whereas the New ZMAX Certificate of Incorporation
prohibits written consent action unless signed by all stockholders. Therefore,
as stockholders of New ZMAX, the former Old ZMAX stockholders will no longer
have the right to act by majority written consent, unless and until the New
ZMAX Certificate of Incorporation is amended to so provide.
 
STOCKHOLDER VOTE FOR MERGERS AND OTHER CORPORATE REORGANIZATIONS
 
  In general, both jurisdictions require authorization by an absolute majority
of outstanding shares entitled to vote, as well as approval by the board of
directors with respect to the terms of a merger or a sale of substantially all
of the assets of the corporation. Neither the Nevada Law nor the Delaware Law
requires stockholder approval by the stockholders of a surviving corporation
in a merger or consolidation as long as the surviving corporation issues no
more than 20% of its voting stock in the transaction.
 
DISSENTERS' RIGHTS
 
  In both jurisdictions, dissenting stockholders of a corporation engaged in
certain major corporate transactions are entitled to appraisal rights.
Appraisal rights permit a stockholder to receive cash equal to the fair market
value of the stockholder's shares (as determined by agreement of the parties
or by a court), in lieu of the consideration such stockholder would otherwise
receive in any such transaction.
 
  Under the Delaware Law, appraisal rights are generally available for the
shares of any class or series of stock of a Delaware corporation in a merger
or consolidation, provided that no appraisal rights are available for the
shares of any class or series of stock which, at the record date for the
meeting held to approve such transaction, were either (i) listed on a national
security exchange or designated as a national market system security on an
interdealer quotation system by the National Association of Securities
Dealers, Inc. ("NASD") or (ii) held of record by more than 2,000 stockholders.
Even if the shares of any class or series of stock meet the requirements of
clause (i) or (ii) above, appraisal rights are available for such class or
series if the holders thereof receive in the merger or consolidation anything
except: (i) shares of stock of the corporation surviving or resulting from
such merger or consolidation; (ii) shares of stock of any other corporation
which at the effective date of the merger or consolidation is either listed on
a national securities exchange, or designated as a national market system
security on an interdealer quotation system by the NASD or held of record by
more than 2,000 stockholders; (iii) cash in lieu of fractional shares; or (iv)
any combination of the foregoing. No appraisal rights are available to
stockholders of the surviving corporation if the merger did not require their
approval.
 
  Under the Nevada Law, a stockholder is entitled to dissent from, and obtain
payment for the fair value of his or her shares in the event of consummation
of a plan of merger or plan of exchange in which the corporation is a party
and, to the extent that the articles of incorporation, bylaws or a resolution
of the board of directors provides that voting or nonvoting stockholders are
entitled to dissent and obtain payment for their shares any corporate action
taken pursuant to a vote of the stockholders. As with the Delaware Law, the
Nevada Law provides an exception to dissenters' rights. Holders of securities
(i) listed on a national securities exchange or designated as a national
market system security on an interdealer quotation system by the NASD or (ii)
held by more than 2,000 stockholders of record are generally not entitled to
dissenters' rights.
 
STOCKHOLDER INSPECTION RIGHTS
 
  The Delaware Law grants any stockholder the right to inspect and to copy for
any proper purpose the corporation's stock ledger, a list of its stockholders,
and its other records. A proper purpose is one reasonably
 
                                      68
<PAGE>
 
related to such person's interest as a stockholder. Directors also have the
right to examine the corporation's stock ledger, a list of its stockholders
and its other records for a purpose reasonably related to their positions as
directors.
 
  The Nevada Law provides the right to inspect the corporation's financial
records for only a shareholder who (i) owns at least 15% of the corporation's
issued and outstanding shares, or (ii) has been authorized in writing by the
holder(s) of at least 15% of the issued and outstanding shares. To inspect the
corporation's stock ledger, the stockholder must have been a stockholder of
record for six months prior to demanding inspection.
 
DERIVATIVE SUITS
  Under both the Delaware Law and the Nevada Law, a stockholder may bring a
derivative action on behalf of the corporation only if the stockholder was a
stockholder of the corporation at the time of the transaction in question or
the stockholder acquired the stock thereafter by operation of law.
 
SPECIAL MEETINGS OF STOCKHOLDERS
  Both the Delaware Law permits special meetings of stockholders to be called
by the board of directors or by any other person authorized in the certificate
of incorporation or bylaws to call a special stockholder meeting. The Nevada
Law does not address the manner in which special meetings of stockholders may
be called. The Old ZMAX Bylaws provide that special meetings of the
stockholders may be called by the President or a director, and that the
President must call such a meeting if requested by beneficial holders of at
least 10% of the outstanding shares of stock of the Company. Similarly, the
New ZMAX Bylaws provide that the President or a director may call a special
meeting of the stockholders, but the New ZMAX Bylaws do not require the
President to call such a meeting unless beneficial holders of at least 25% of
the outstanding shares of stock so request. Since New ZMAX requires a greater
number of shares to force a special meeting of stockholders, it could be more
difficult for the stockholders to force a special meeting as stockholders of
New ZMAX than when they were stockholders of Old ZMAX.
 
                 STOCKHOLDER PROPOSALS FOR 1998 ANNUAL MEETING
 
  Any stockholder of the Company wishing to submit a proposal for action at
the Company's 1998 annual Meeting of Stockholders and desiring the proposal to
be considered for inclusion in the Company's proxy materials must provide a
written copy of the proposal to the management of the Company at its principal
executive office not later than    , 1998, and must otherwise comply with
rules of the SEC relating to stockholder proposals.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To ZMAX Corporation:
 
  We have audited the accompanying consolidated balance sheets of ZMAX
Corporation (a Nevada corporation in the development stage) and its subsidiary
as of December 31, 1995 and 1996, and the related statements of operations,
stockholders' equity (deficit), and cash flows for the period from inception
(December 13, 1995) to December 31, 1995, for the year ended December 31, 1996
and for the period from inception (December 13, 1995) to December 31, 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 an audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatements. 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
statements 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 ZMAX Corporation and its
subsidiary as of December 31, 1995 and 1996, and the results of its operations
and its cash flows for the period from inception to December 31, 1995, for the
year ended December 31, 1996 and for the period from inception to December 31,
1996, in conformity with generally accepted accounting principles.

                         (A DEVELOPMENT STAGE COMPANY)
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                            AS OF DECEMBER 31, 1996
 
1. BASIS OF PRESENTATION, ORGANIZATION, AND NATURE OF OPERATIONS:
 
 Basis of Presentation
 
  On November 6, 1996, ZMAX Corporation ("ZMAX"), a shell company listed on
the OTC Bulletin Board, acquired 100% of the outstanding common stock of
Century Services, Inc. ("CSI"), a Maryland corporation. CSI was a privately
held company formed on December 13, 1995 to perform computer re-engineering
with a focus on providing a solution to the year 2000 problem.
 
  For financial reporting purposes, the acquisition has been treated as a
recapitalization of CSI with CSI as the acquirer (a reverse acquisition). The
historical financial statements prior to November 6, 1996 are those of CSI.
The accompanying consolidated financial statements include all of the accounts
of CSI and the accounts of ZMAX for the period from the acquisition on
November 6, 1996, through December 31, 1996. All significant intercompany
amounts have been eliminated.
 
  ZMAX and its subsidiary, CSI (together the "Company"), are considered
development stage companies as defined by Statement of Financial Accounting
Standards ("SFAS") No. 7, "Accounting and Reporting by Development Stage
Enterprises." All losses since inception are considered development stage
activities and are presented on the basis described above.
 
 Organization of ZMAX
 
  ZMAX was incorporated as a Nevada corporation on April 24, 1986, under the
name of Pandora, Inc. ("Pandora"), for the purpose of creating a vehicle to
obtain capital to seek out, investigate and acquire interests in products,
properties and businesses which, in the opinion of management, may have
potential for profit. Until May 4, 1992, Pandora transacted no business other
than the investigation of various business opportunities. On May 4, 1992,
Pandora amended its Articles of Incorporation to change the name of the
Company to Oryx Gold Corporation ("Oryx") in connection with a reorganization
in which Oryx acquired 100% ownership of American Oil and Gas Corporation
("American Oil"). American Oil was organized on November 22, 1991, as a Nevada
corporation, and conducted no business other than the acquisition of an
interest in certain unpatented placer mining claims in Nevada. Oryx intended
to develop the mining claims and other acquired interests and, on August 16,
1995, changed its name to Mediterranean Oil Corporation ("Mediterranean") to
more accurately reflect the nature of its business. The Company did not
subsequently pursue this business. American Oil's corporate status has been
suspended by the Secretary of State of Nevada as of December 1, 1995, and this
subsidiary has been abandoned. On August 9, 1996, Mediterranean changed its
name to ZMAX Corporation.
 
 Nature of Operations
 
  Prior to the CSI transaction, ZMAX's activities consisted of efforts to
establish a new business and raise capital. The operations of CSI consisted of
activities to obtain financing, to acquire and develop its proprietary Year
2000 software re-engineering tools and methodologies, and to market its
services to potential customers. Since the acquisition of CSI, the Company has
been focused on the software re-engineering market. The Company has not yet
generated any revenues and has no assurance of future revenues. Even if
marketing efforts are successful, substantial time will pass before
significant revenues will be realized and, during this period, the Company may
require additional funds that may not be available to it.

                        ZMAX CORPORATION AND SUBSIDIARY
                         (A DEVELOPMENT STAGE COMPANY)
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  The Company has limited experience in providing its Year 2000 or
"millennium" services. The Company has not completed a large-scale millennium
conversion project either alone or together with a strategic partner. There
can be no assurance that the Company will be successful in completing large-
scale conversions, that the Company will not experience delays or failures in
providing its millennium services, or that its millennium services will be
effective. The failure of the Company's Year 2000 methodology to function
properly or the existence of significant errors or bugs following completion
of millennium conversions could necessitate significant expenditures by the
Company to remedy the problem. The consequences of failures, errors or bugs
could materially and adversely affect the Company's business, operating
results and financial condition.
 
  The Company's operations are subject to certain risks and uncertainties,
including among others, rapidly changing technology, uncertain and undeveloped
markets for millennium services, current and potential competitors with
greater financial, technological, production and marketing resources, the need
to develop additional products and services, limited protection of proprietary
information, the risk of third party claims of infringement, potential
contract liability related to the Company's access to key aspects of customers
computer systems, dependence upon strategic alliances, the need for additional
technical personnel, dependence on key management personnel, management of
growth, uncertainty of future profitability and possible fluctuations in
financial results. In addition, there are risks associated with the market
activity in ZMAX stock. The potential volatility of the stock price is
demonstrated by the quoted market price compared to the prices in the CSI
recapitalization transactions. The limited public information on the Company
and its security holders and the limitations on the ability to enforce
securities laws against non-U.S. persons also creates risk.
 
2. EXCHANGE OFFER AND PROPOSED MERGER
 
 Exchange Offer
 
  In connection with the offer anticipated by this prospectus, the Company
will offer (the "Exchange Offer") to exchange $5,500,000 of outstanding
Convertible Exchangeable Subordinated Debentures (the "Debentures") under the
terms and conditions included in this prospectus. Each Debenture holder will
receive 220 shares of common stock and a warrant to purchase 220 shares of
common stock (the "Warrant Shares") per $1,000 principal amount of Debentures
exchanged (see Note 7). Any accrued but unpaid interest from June 1, 1997 (the
most recent interest payment date) to the date of the exchange will be waived
by the Debenture holder. Following
 
                                      F-8

                        ZMAX CORPORATION AND SUBSIDIARY
                         (A DEVELOPMENT STAGE COMPANY)
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
the Exchange Offer, the Company intends to redeem any Debentures still
outstanding at 100% of the principal amount pursuant to the terms of the
Debentures, plus any interest accrued thereon to the date of redemption.
 
  Because the securities to be issued pursuant to the terms of the Exchange
Offer include securities in excess of the securities issuable pursuant to the
original conversion terms of the Debentures (see Note 7), the Company will
recognize as expense, at the time of the exchange, the fair value of the
securities issued upon the exchange of the Debentures in excess of the fair
value of the securities issuable pursuant to the original conversion terms of
the Debentures. The amount of the expense will equal the fair value of the
incremental number of shares of common stock issued in the exchange in excess
of the number of shares issuable upon conversion of the Debentures in
accordance with their terms plus the fair value of the warrants issued in the
exchange.
 
 Proposed Merger (the "Merger")
 
  ZMAX proposes to merge with and into New ZMAX Corporation, a Delaware
corporation ("New ZMAX"), pursuant to an Agreement and Plan of Merger between
ZMAX and New ZMAX (the "Merger Agreement"). At the time the Merger becomes
effective (the "Effective Time"), each outstanding share of Common Stock,
$0.001 par value, of ZMAX ("Old ZMAX Common Stock") will be converted into the
right to receive, and will be exchangeable for one share of Common Stock,
$0.001 par value, of New ZMAX ("New ZMAX Common Stock"). At the Effective Time
of the Merger, ZMAX will be merged with and into New ZMAX and ZMAX will cease
to exist as a corporation. New ZMAX will be the surviving corporation in the
Merger, and CSI will thereby become a wholly owned subsidiary of New ZMAX.
Stockholders who oppose the proposed Merger will have the right to receive
payment for the value of their shares under Nevada law. In addition, if
beneficial owners of more than 5% of the issued and outstanding shares of ZMAX
Common Stock exercise their dissenters' rights, the Company may abandon the
Merger.
 
  The exchange of at least 90% of the Debentures for ZMAX Common Stock and the
exercise of Warrants for at least 80% of the Warrant Shares are conditions to
the consummation of the Merger. Approval of the Merger also requires the
affirmative vote of the holders of a majority of the outstanding shares of
ZMAX Common Stock entitled to vote.
 
  The authorized capital stock of the ZMAX consists of 95,000,000 shares of
Old ZMAX Common Stock and 10,000,000 shares of preferred stock, of which
5,000,000 shares have been designated as Series A Preferred Shares. Upon
completion of the Merger, the authorized capital stock of New ZMAX will
consist of 50,000,000 shares of Common Stock and 10,000,000 shares of
Preferred Stock. The authorized shares have been retroactively adjusted to
give effect to this event. This action is subject to the consummation of the
Merger.
 
3. SIGNIFICANT ACCOUNTING POLICIES:
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally

disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Cash and Cash Equivalents
 
  Investments with original maturities of three months or less are considered
cash equivalents for purposes of these financial statements.
 
 Income Taxes
 
  The Company accounts for income taxes in accordance with SFAS No. 109,
"Accounting for Income Taxes." Under SFAS No. 109, deferred tax assets and
liabilities are computed based on the difference between the financial
statement and income tax bases of assets and liabilities using the enacted
marginal tax rate. SFAS No. 109 requires that the net deferred tax asset be
reduced by a valuation allowance if, based on the weight of available
evidence, it is more likely than not that some portion or all of the net
deferred tax asset will not be realized.
 
 Long-Lived Assets
 
  The Company reviews its long-lived assets, including property and equipment,
identifiable intangibles, and goodwill whenever events or changes in
circumstances indicate that the carrying amount of the assets may not be fully
recoverable. To determine recoverability of its long-lived assets, the Company
evaluates the probability that future undiscounted net cash flows will be less
than the carrying amount of the assets.
 
 Software Development Costs
 
  SFAS No. 86, "Accounting for the Costs of Computer Software to be Sold,
Leased or Otherwise Marketed," requires the capitalization of certain computer
software development costs incurred after technological feasibility is
established. Amounts that could have been capitalized under this statement
were immaterial and have not been capitalized.
 
 Net Loss Per Share
 
  Net loss per share for the period from December 13, 1995 (date of inception)
to December 31, 1995 and for the year ended December 31, 1996 and the three
months ended March 31, 1996 and 1997 is based upon the weighted-average number
of common equivalent shares outstanding during the period. The effects of
outstanding options and convertible debt on net loss per share are not
included because such effects would be anti-dilutive. Outstanding shares
subject to cancellation agreements (see Note 9) are also not included. Fully
diluted earnings per share are not presented because the difference between
these amounts and amounts presented is not material.
 
 Interim Financial Information
 
  The unaudited consolidated financial statements as of March 31, 1997, and
for the three months ended March 31, 1996 and 1997, presented herein have been
prepared by the Company without audit, pursuant to the rules and resolutions
of the Securities and Exchange Commission. The financial statements reflect
all adjustments (consisting of normal recurring adjustments) which, in the
opinion of management are necessary to present fairly the financial position,
results of operations and cash flows of the Company as of March 31, 1996 and
1997, and for the three months then ended. The results of operations for the
three months ended March 31, 1997 are not necessarily indicative of the
results that may be expected for the year ended December 31, 1997.

4. CSI RECAPITALIZATION AND ACQUISITION OF JOINT VENTURE INTEREST:
 
  In connection with the recapitalization of CSI, ZMAX issued 2,800,000 shares
of common stock at $0.30 per share (see Note 9), $2,100,000 of convertible
notes (see Note 7) and $5,500,000 of convertible exchangeable subordinated
debentures (see Note 7).
 
 Fiserv Century Services Joint Venture
 
  On April 17, 1996, CSI formed the Fiserv Century Services Joint Venture (the
"JV") with Fiserv Federal Systems, Inc., ("Fiserv"). CSI and Fiserv each owned
a 50% interest in the JV. The JV was engaged in the business of marketing Year
2000 computer consulting services using computer software exclusively licensed
to CSI.
 
  As funding for the JV, Fiserv agreed to provide a credit facility of up to
$5 million with interest payable monthly on the outstanding balance at a rate
of the prime rate plus 2%. A security interest in the JV's assets was granted
to Fiserv as security for payment of the obligations. All funds advanced to
the JV were provided under this agreement. In addition, the JV agreed to
provide monthly advances to CSI in the amount of $40,000 with a limit of
$720,000. No stated interest was due on those advances pursuant to the
agreement. During the period from April 1996 to August 1996, Fiserv provided a
total of $695,000 in funding to the JV, $560,000 of which the JV advanced to
CSI under the terms of the agreements described above.
 
  As part of the CSI recapitalization, Fiserv agreed to sell its interest in
the JV to ZMAX. Effective September 1, 1996, NewDominion Capital Group, Inc.
("NewDominion") acquired Fiserv's interest in the JV. At this time, all
employees and operations of the JV were transferred to CSI. NewDominion's
intent was to serve as an intermediary in order to assign the joint venture
interest to ZMAX concurrent with the recapitalization of CSI. Fiserv's
interest was assigned to NewDominion for cash consideration of $310,000 and a
promissory note of $385,000. NewDominion granted a security interest to Fiserv
of its rights and interest in the JV as security for the $385,000 note. In
addition to the above consideration, Fiserv was pledged 3% of the outstanding
shares of the anticipated successor entity to the JV.
 
  On September 20, 1996, NewDominion assigned its interest in the JV to ZMAX.
As consideration for the assignment, ZMAX assumed all liabilities, interests,
and obligations of NewDominion related to the JV including the $310,000
payable to Fiserv and the $385,000 promissory note. As the successor entity
(as described above), ZMAX assumed the obligation to issue a 3% ownership
interest in ZMAX to Fiserv.
 
  This transaction has been, accounted for as a purchase by ZMAX. ZMAX
acquired the 50% interest in the JV for repayment of the amounts advanced by
Fiserv to the JV totaling $695,000 ($310,000 in cash and $385,000 note
payable) and 234,365 shares of ZMAX common stock with a fair value of
$1,373,379 based upon the quoted market price of ZMAX common stock. The
234,365 shares of common stock were not issued until April 1997 and have been
reflected as issuable as of December 31, 1996. The fair value of these shares
is included in stockholders' equity in the accompanying financial statements
as of December 31, 1996.
 
  The purchase price has been allocated to assets and liabilities based on
their estimated fair values at the date of acquisition on a preliminary basis
as follows.

  As of September 1, 1996, all operations, some of which had previously been
performed by the JV, were carried out by CSI. After the CSI transaction, ZMAX
transferred all of its interest in the JV to CSI as of January 1, 1997, and,
CSI as the sole remaining venture partner, terminated the JV.

 CSI
 
  On July 16, 1996, PRCC, Inc. ("PRCC") entered into an agreement with CSI to
acquire all of the outstanding stock of CSI. On September 20, 1996, PRCC
assigned its rights under the July 16, 1996 agreement with CSI to ZMAX in
return for $20,000 in cash and the right to purchase 350,000 shares of ZMAX
common stock for $0.30 per share. The $20,000 and fair value of, based upon
the quoted market price of the ZMAX common stock, of these shares has been
charged to expense as a cost of the CSI transaction and is included in other
expenses in the accompanying financial statements for the year ended December
31, 1996. These shares were not issued until April 1997 and have been
reflected as issuable as of December 31, 1996. The fair value of these shares
is included in stockholders' equity in the accompanying financial statements
as of December 31, 1996. Similarly, the subscription proceeds were not
received until May 1997, and have been reflected as stock subscriptions
receivable as of December 31, 1996.
 
  Concurrent with this assignment, on September 20, 1996, ZMAX made an offer
to purchase all of the outstanding shares of CSI stock. The offer was accepted
by the stockholders of CSI and the agreement was announced to the public on
September 26, 1996. The September 20, 1996, agreement also provided that ZMAX
would advance amounts to CSI to fund their operations, CSI would enter into
employment agreements with certain executives who were the former stockholders
of CSI that provide for compensation at specified levels, and the former
stockholders of CSI were provided with certain anti-dilution protection with
respect to their future ownership interest in ZMAX provided that certain
performance criteria were met. These performance criteria were not
subsequently met and the former CSI stockholders are not entitled to the anti-
dilution protection prescribed in the agreement.
 
  During the period from September 20, 1996 to November 6, 1996, ZMAX advanced
a total of $390,000 to CSI under two promissory notes totaling $200,000 and
under a line of credit agreement totaling $190,000. The stockholders of CSI
assigned a security interest in their CSI stock to ZMAX as consideration for
these advances.
 
  On November 6, 1996, the Stock Purchase Agreement between CSI and ZMAX was
executed and the transaction was consummated. In return for all of the
outstanding stock of CSI, ZMAX issued 3,200,000 shares of common stock. At
closing, the former stockholders of CSI received 400,000 shares of ZMAX stock.
The remaining 2,800,000 shares (the "Escrowed Stock") were placed in escrow
subject to quarterly release based upon the cash flow (as defined) of CSI.
Under the terms of the Stock Purchase Agreement one share of Earn Out Stock
will be released for every $1.25 of cash flow generated. The stockholders are
entitled to vote the shares of the Escrowed Stock as well as to receive their
respective pro rata share of any distributions or dividends. The Escrowed
Stock is subject to forfeiture under certain conditions (see Note 12).
 
  This transaction has been accounted for as a recapitalization of CSI with
CSI as the acquirer (a reverse acquisition). The fair value of the Earn Out
Stock will be recognized as compensation expense in the period in which the
shares are earned and released from escrow.
 
  In connection with the transaction described above, the Company incurred
$54,678 of direct costs that have been charged to expense. The Company also
agreed to issue 320,000 shares of the Company's common stock to a consultant
for services related to the CSI transaction and related financing. The fair
value, based upon the quoted market price of the ZMAX common stock, of 160,000
of these shares has been charged to expense as a cost of the transaction and
is included in other expenses in the accompanying financial statements for the
year ended December 31, 1996. The fair market value of the other 160,000
shares has been recognized as a deferred financing cost in the accompanying
financial statements for the year ended December 31, 1996 (See Note 7). The
shares granted to the investment advisor were not issued until April 1997, and
are reflected as issuable as of December 31, 1996. The fair value of these
shares is included in stockholders' equity in the accompanying financial
statements as of December 31, 1996.

6. INTANGIBLE ASSETS:
 
  Intangible assets consist of purchased software rights and intangibles
acquired as a result of ZMAX's purchase of Fiserv's interest in the JV. The
software rights and other intangibles are being amortized over their estimated
useful lives of five years. Accumulated amortization totaled $193,261 and
$341,870 (unaudited) as of December 31, 1996 and March 31, 1997, respectively.
 
  During 1996, CSI purchased the rights to three software tools for a total of
$1,010,000. The remaining obligation is due in $150,000 installments in April
1997, October 1997, and April 1998 (see Note 7) while this obligation called
for fixed payments, it did not bear interest. Accordingly, interest has been
imputed at 10% on this obligation.
 
  Two of the licenses provide for the exclusive rights to use and modify the
software for a term of 20 years. The third license, for the Change of Century
Analysis and Conversion Tool ("COCACT"), provides for the exclusive rights to
use the software in North America for a term of ten years (the "North American
COCACT License").
 
  On April 30, 1997, the Company entered into an agreement to purchase all
right, title and interest to COCACT (the "COCACT Purchase Agreement").
Conditions of the purchase included a software development and enhancement
project to bring COCACT to the required level of performance as specified in
the agreement. The purchase price for the COCACT software is $1,100,000, of
which $250,000 was paid in May 1997, plus 150,000 shares of common stock of
the Company issuable upon completion and testing of the COCACT enhancements.
The remaining installments of $283,333 each are due in September 1997, January
1998, and May 1998. The balance of the purchase price will be payable
contingent upon the completion of the software development and enhancement
project by September 30, 1997. Under the terms of the COCACT Purchase
Agreement, the Company may terminate the agreement if, among other things, the
enhancement project is not satisfactorily completed. Upon termination and
recision of the software sale, the Company has the right to return the
software and treat the $250,000 payment made in May 1997 as prepayment of the
license fees payable under the North American COCACT License.
 
  As of April 30, 1997, $300,000 under the original North American COCACT
License remained unpaid, due in installments of $150,000 each in October 1997
and April 1998. Under the terms of the COCACT Purchase Agreement, ZMAX has the
right to terminate and cancel the North American COCACT License including the
obligation to pay any remaining license fees. In the event that ZMAX exercises
its right to cancel the COCACT Purchase Agreement, termination of the North
American COCACT License would be automatically rescinded, whereupon ZMAX's
right and obligations under the North American COCACT License would be
reinstated retroactively.

 Promissory Note Payable
 
  In September 1996, the Company assumed a $385,000 promissory note payable to
Fiserv as consideration for the purchase of a 50% interest in the JV. In May
1997, the $385,000 note payable and the related accrued interest of $20,776 as
of March 31, 1997, were settled by the Company by issuing 32,077 shares of
common stock.
 
 Convertible Notes
 
  In connection with the CSI recapitalization, from September 1996 to October
1996, the Company issued a total of $1,980,000 in convertible notes (the
"Notes"). After the date of the CSI transaction, the Company issued an
additional $120,000 in Notes. The Notes are convertible, at the option of the
holder, into a total of 1,600,000 shares of the Company's common stock. Of the
total, $600,000 of the Notes are convertible at a rate of one share per $1.00
of principal. The remaining $1,500,000 are convertible at a rate of one share
per $1.50 of principal. Principal of $1,350,000 is due on January 20, 1997,
and $750,000 due on March 20, 1997 after which the Notes were convertible. In
1997, all of the holders exercised their conversion rights and in March 1997,
the Board of Directors approved the conversion and in April 1997, the Notes
were converted into 1,600,000 shares of common stock.
 
  On the respective dates of issuance of the Notes, the conversion price of
the Notes was less than the quoted market price of the common stock.
Accordingly, because the intrinsic value of this beneficial conversion feature

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
exceeds the amount of the proceeds of the Notes, the entire $2,100,000 in
proceeds have been allocated to additional paid-in capital to recognize this
beneficial conversion feature. The discount on the Notes resulting from the
allocation of proceeds to the beneficial conversion feature is reflected as a
charge to interest expense and is being recognized over the period until the
Notes become convertible. A total of $1,508,592 in interest expense has been
recognized for the year ended December 31, 1996 related to the discount
resulting from the beneficial conversion feature.
 
 Convertible Exchangeable Subordinated Debentures
 
  On December 6, 1996, the Company issued $5,500,000 in convertible
exchangeable subordinated debentures (the "Debentures"). Prior to the maturity
date or redemption by the Company, a holder may convert the entire principal
balance of their Debenture into common stock. Upon conversion, the holder will
receive one share of stock for each $5.00 of principal amount of the
Debenture. The Company may redeem or prepay the Debentures provided that the
Company has offered to exchange the Debentures for the Company's common stock
and a warrant to purchase additional common stock and the Company has filed an
effective registration statement pursuant to the Securities Act of 1933, as
amended, pertaining to the exchange offer.
 
  If the exchange offer is made on or before the six month anniversary of the
Debentures, each $5.00 of principal will be exchanged for one share of common
stock plus a warrant to purchase one share of common stock. If the exchange
offer is made after the six month anniversary of the debentures, each $5.00 of
principal will be exchanged for one and one-tenth (1.1) share of stock plus an
equivalent number of warrants.
 
  Upon exchange, the holder will receive common stock plus, for each share of
common stock received, one warrant to purchase an additional share of ZMAX
common stock at $7.00 per share if exercised prior to the first anniversary of
the date of issuance of the warrant or at $8.00 per share if exercised prior
to the second anniversary of the date of issuance of the warrant. The warrants
expire on the second anniversary of the date of issuance.
 
  On the date of issuance of the Debentures, the conversion price of the
Debentures was less than the quoted market price of the Company's common
stock. Accordingly, because the intrinsic value of this beneficial conversion
feature exceeds the amount of the proceeds of the Debentures, the entire
$5,500,000 in proceeds have been allocated to additional paid-in capital to
recognize this beneficial conversion feature. The discount resulting from the
allocation of proceeds to the beneficial conversion feature is reflected as a
charge to interest expense and has been recognized in December 1996 as the
Debentures are immediately convertible by the holders. A total of $5,500,000
in interest expense has been recognized for the year ended December 31, 1996
related to the discount resulting from the beneficial conversion feature.
 
 Deferred Financing Costs
 
  Deferred financing costs, which were incurred in connection with the
issuance of the Notes and the Debentures, are charged to expense as additional
interest expense over the life of the debt, using the interest method.
Amortization of the deferred financing costs totaled $185,767 for the year
ended December 31, 1996.

                         (A DEVELOPMENT STAGE COMPANY)
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  The Company has determined that its deferred tax assets did not satisfy the
recognition criteria set forth in SFAS No. 109, and, accordingly, established
a valuation allowance for 100 percent of the deferred tax assets.
 
  As of December 31, 1996, the Company had net operating losses of
approximately $1,400,000 available for carryforward to offset future taxable
income. These carryforwards expire in years 2001 through 2011. Under the
provisions of the Tax Reform Act of 1986, when there has been a change in an
entity's ownership of 50 percent or greater, utilization of net operating loss
carryforwards may be limited. As a result of ZMAX's equity transactions
occurring through December 31, 1992 and the equity transactions in 1996
including the CSI acquisition, the Company's net operating losses will be
subject to such limitations and may not be available to offset future income
for taxes purposes.
 
9. COMMON STOCK AND PREFERRED STOCK:
 
 Reverse Stock Split
 
  Effective July 23, 1996, ZMAX effected a 1 for 80 reverse stock split. All
share amounts and per share amounts have been retroactively restated to
reflect this event.
 
 OffShore Placement
 
  In September 1996, ZMAX sold 2,800,000 shares at $.30 per share to offshore
investors (the "OffShore Placement"). The proceeds were used to repay existing
debt of ZMAX (see Note 11 for a discussion of related party transactions).
 
 Stock Subject to Cancellation
 
  By an agreement dated April 27, 1992, ZMAX acquired all of the outstanding
common stock of American Oil for 625,000 common shares of ZMAX's stock,
5,000,000 preferred shares of ZMAX's stock and sold an additional 88,266
common shares of the Company's stock for $7,062 in cash. The preferred shares
were never issued and American Oil has not undertaken any business or any
financial transaction other than the acquisition of certain mining rights and
American Oil's corporate status has been suspended by the State of Nevada and
this subsidiary has been abandoned by the Company.
 
  In September 1995, ZMAX entered into stock cancellation agreements with
certain stockholders that provided for the cancellation of the aforementioned
shares of the Company's stock. As of December 31, 1996, these shares had not
been cancelled. In March 1997, 296,007 of these shares were cancelled. An
additional 479,801 shares are subject to cancellation but were not cancelled
as of March 31, 1997.
 
  Due to a lack of documentation and proper signature guarantees, 167,301 of
the shares remain outstanding and have been reported as lost by the
stockholder. Assuming the stockholder will provide necessary documentation,
these lost certificates may be cancelled of record upon the Company's
agreement to indemnify the transfer agent and the reservation of an equal
number of shares against the possible presentation of a lost certificate by a
bona fide holder. In the event of presentation of a lost certificate for
transfer, the shares would be transferred to the presenting bona fide holder
from the shares reserved for this purpose. In such event, the Company may
pursue indemnification remedies against the former stockholder under a lost
stock indemnity agreement signed by the former stockholder in October 1996.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  The remaining 312,500 shares subject to cancellation have been lost by
another stockholder. The Company has been unable to cancel these shares of
record due to the lack of proper documentation. The Company's attempts to
locate the stockholder to correct document deficiencies have been unsuccessful
and the Company has currently decided to abandon its efforts to do so. The
Company is currently considering obtaining a court order to cancel these
shares of record.
 
 Reserved Shares
 
  The Company has reserved 1,820,000 shares of Common Stock for issuance under
its stock incentive and option plans and executive bonus program (see Notes 10
and 12).
 
 Preferred Stock
 
  As of December 31, 1995 and 1996, there were no shares of Preferred Stock
issued and outstanding. If issued, holders of Series A Preferred Stock would
be entitled to convert each share of Series A Preferred Stock into fair shares
of Common Stock at the option of the holder. In all other respects, the voting
powers, preferences, limitations, restrictions and relative rights of the
Series A Preferred Stock are the same as those of the Common Stock.
 
10. STOCK OPTIONS AND STOCK-BASED COMPENSATION:
 
  In October 1995, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 123, "Accounting for Stock-Based Compensation." SFAS No. 123 is
effective for awards granted in 1996 and 1995. SFAS No. 123 defines a "fair
value based method" of accounting for stock-based compensation. Under the fair
value based method, compensation cost is measured at the grant date based on
the fair value of the award and is recognized over the service period. Prior
to issuance of SFAS No. 123, stock-based compensation was accounted for under
the "intrinsic value method" as defined by APB Opinion No. 25, "Accounting for
Stock Issued to Employees." Under the intrinsic value method, compensation is
the excess, if any, of the market price of the stock at grant date or other
measurement date over the amount an employee must pay to acquire the stock.
 
  SFAS No. 123 allows an entity to continue to use the intrinsic value method.
However, entities electing the accounting in Opinion No. 25 must make pro
forma disclosures as if the fair value based method of accounting had been
applied. The Company applies APB Opinion No. 25 and the related
interpretations in accounting for its stock-based compensation.
 
  Under the provisions of SFAS No. 123, transactions with other than employees
in which services are the consideration received for the issuance of equity
securities shall be accounted for based upon the fair value of the
consideration. The only options granted in 1996 were granted to a consultant
and were accounted for at fair value. Accordingly, no pro forma disclosures
are required for the year ended December 31, 1996.
 
 ZMAX Options
 
  Prior to the CSI recapitalization, ZMAX granted options to certain of its
officers and directors, some of which remain outstanding as of December 31,
1996. In September 1994, the Company granted 6,565 options to its officers and
directors. The options were contingent upon service to ZMAX as a director,
officer, employee or consultant to the Company. As a result of the termination
of service by these individuals, these options were canceled in 1996. In June
1995, the Company granted 14,940 additional options to officers and directors.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
options were to survive the appointment of these individuals and expire in
September 1997. None of these individuals remain in service with the Company
and in 1996, 7,814 of these options were canceled. An additional 1,876 were
canceled in May 1997.
 
 Non-Employee Options
 
  In September 1996, ZMAX granted 200,000 options to a consultant at exercise
prices ranging from $5.00 to $15.00 under the terms of a one-year consulting
agreement. Under the terms of the agreement, the options vested ratably over
the term of the agreement. The Company has recorded approximately $300,000 of
compensation expense related to these options for the year ended December 31,
1996 based upon the fair value of the options on the date of grant and the
vesting period. In May 1997, the consulting agreement was amended such that
the consultant's options were canceled and the consultant was granted 60,000
shares of the Company's common stock for services performed from September
1996 to May 1997. The difference between the fair value of the shares to be
issued and the cumulative compensation expense recorded as of the date the
agreement was amended will be charged to expense in May 1997.
 
  The following is a summary of ZMAX options granted prior to the CSI
recapitalization.

 1997 Stock Incentive Plan
 
  In May 1997, the Board of Directors adopted the 1997 Stock Incentive Plan
(the "Incentive Plan"), subject to the approval of the stockholders. The
purpose of this plan is to provide additional compensation to employees,
officers, directors and consultants of the Company or an affiliate. Under the
terms of the Incentive Plan, 1,700,000 shares of common stock have been
reserved for issuance as incentive awards under the plan. The number of shares
of common stock associated with any forfeited stock incentive will be added
back to the number of shares that can be issued under the Incentive Plan.
Awards under the Incentive Plan and their terms will be determined by a
committee (the "Committee") selected by the Board of Directors. The Incentive
Plan permits the Committee to make awards of a variety of equity-based
incentives (collectively, "Stock Incentives").
 
  The Incentive Plan allows for the grant of incentive stock options and non-
qualified stock options. The exercise price of the options will be established
by the Committee. The exercise price of an incentive stock option may not be
less than the fair market value of the Common Stock on the date of the grant
(or less than 110% of

the fair market value if the participant controls more than 10% of the voting
power of the Company or a subsidiary). Non-qualified stock options may be made
exercisable at a price equal to, less than or more than the fair market value
of the Common Stock on the date that the option is awarded. The term of an
option will be specified in the applicable stock incentive agreement.
 
  In addition to stock options, the Incentive Plan also makes provisions for
other Stock Incentives, including stock appreciation rights, stock awards,
phantom shares, performance unit appreciation rights and dividend equivalent
rights. These Stock Incentives will be subject to the terms prescribed by the
Committee in accordance with the provisions of the Incentive Plan. The Stock
Incentives are generally not transferable or assignable during a holder's
lifetime.
 
  In April 1997, the Company granted 1,200,000 non-qualified stock options
under the Incentive Plan to certain officers and employees. These options have
an exercise price of $14.31, expire ten years after the date of grant, and
will become fully vested after seven years, vesting may be accelerated
provided that certain revenue targets are achieved.
 
 1997 Directors Formula Stock Option Plan
 
  In May 1997, the Board of Directors adopted the 1997 Directors Formula Stock
Option Plan (the "Director Plan"). The Board of Directors has reserved 120,000
shares of Common Stock for issuance pursuant to awards which may be made under
the Director Plan. The number of shares of Common Stock associated with any
forfeited options are added back to the number of shares that can be issued
under the Director Plan.
 
  The awards under the Director Plan are determined by the express terms of
the Director Plan. The Director Plan will be administered by a committee (the
"Committee"), the members of which are appointed by the Board of Directors.
The Committee will consist of at least one or more members of the Board of
Directors who will not receive a grant of an option under the Director Plan
and who are not currently eligible to receive a grant of an option under the
Director Plan. The Committee will have the authority in its sole discretion to
interpret the Director Plan and to make all other determinations and to take
all other actions it deems necessary or advisable for the implementation and
administration of the Director Plan.
 
  Generally, only nonemployee directors of the Company who do not perform
services for the Company are eligible to participate in the Director Plan. The
Director Plan provides for option grants upon a nonemployee director's initial
appointment after May 20, 1997 to the Board of Directors to purchase 12,000
shares of Common Stock. The nonemployee director will vest immediately in
8,000 shares of Common Stock and will vest in an additional 2,000 shares after
the completion of the first year of continued service and an additional 2,000
shares after the completion of the second year of continued service. Each
option granted pursuant to the Director Plan will be evidenced by an agreement
and will be subject to additional terms as set forth in the agreement. Options
become exercisable when vested and expire 10 years after the date of grant,
subject to such shorter period provided in the agreement.
 
  On May 20, 1997, 36,000 stock options were issued under the terms of the
Director Plan to three eligible directors. The exercise price of these options
is $14.06. The vesting schedule and exercise period is in accordance with the
terms described above.

11. RELATED PARTY TRANSACTIONS:
 
  In connection with the recapitalization of CSI, a consultant to the Company
and/or his affiliate was issued 320,000 shares of the Company's stock for

used to satisfy this obligation. This individual has been a consultant to ZMAX
since 1994. The Company continues to retain this individual as a consultant at
$10,000 per month. In connection with the recapitalization of CSI, $280,000 of
consulting fees owed to this individual were satisfied in 1996 by issuing
$280,000 of convertible notes. In addition to incurring $120,000 in consulting

for expenses incurred on behalf of ZMAX.
 
  In connection with the assignment of NewDominion's interest in the JV to the

 Employment and Consulting Agreements
 
  CSI has entered into employment agreements with two executives who were the
former stockholders of CSI. The agreements provided for a base salary plus a
bonus based upon CSI's cash flow (as defined in the agreement). The term of
the agreements began in November 1996 and extend for a period of three years.
 
  One of the former stockholders of CSI resigned from the Company in April
1997. Pursuant to the terms of his employment agreement with CSI and his
separation agreement with CSI, he is collecting severance from the Company in
the amount of $100,000 per year through November 1999. This individual will
still be entitled to receive his pro rata share of the Escrowed Stock as it is
released from escrow provided that he does not violate the non-compete, non-
solicitation, or proprietary information restrictions contained in his
employment agreement.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  The other former stockholder of CSI remains an officer and director of the
Company. In May 1997, his employment agreement was amended effective January
1, 1997. Under the terms of this agreement this employee will receive a base
salary plus bonus of up to 100% of his base salary, if the Company reaches
certain specified levels of revenue and profitability. If the bonus is earned
in 1997 it will be payable in 25% cash and 75% common stock. The number of
shares to be issued will be based upon the fair market value of the Company's
common stock at the end of the fiscal year. For fiscal years 1998 and 1999,
the Compensation Committee of the Company will set new performance criteria
and establish the percentage of the bonus to be paid in cash or options for
that year.
 
  In the event that the employment agreement is terminated by the death or
permanent disability (as defined in the agreement) of the executive or by the
Company without cause (as defined in the agreement), severance payments at an
annual rate of $100,000 for the remaining term of the agreement will be due to
the executive or the executive's estate. The executive is subject to certain
noncompete and nonsolicitation provisions for a period of two years after
termination of the agreement.
 
  In order to ensure that CSI had adequate funds to pay the compensation of
the executives under the original employment agreements, the Company placed
$200,000 in escrow. Each month beginning in December 1996, $16,667 will be
released from escrow to the operating account of CSI. Accordingly, as of
December 31, 1996, $184,016 represents restricted cash and is included in the
cash balance.
 
  In June 1997, the Company entered into a three year employment agreement
with its Senior Vice-President--Technology. Under the terms of this agreement
this employee will receive an annual base salary plus a bonus. For fiscal
years 1997, 1998 and 1999 the employee is eligible to receive a bonus of up to
100% of his base salary, if the Company reaches certain specified levels of
financial performance. If the bonus is earned in 1997 it will be payable in
50% cash and 50% stock. For fiscal years 1998 and 1999, the Compensation
Committee of the Company will set new performance criteria and establish the
percentage of the bonus to be paid in cash or options for that year.
 
  In April 1997, the Company entered into a three year consulting agreement
with the Chairman of the Board of Directors. Under the terms of this agreement
the consultant will be compensated at $20,000 per month. This agreement can be
terminated by the Company at any time; however, if the consultant is
terminated without cause, the Company is required to continue to pay the
consultant for the shorter of one year or the remaining term of the agreement.
The agreement also contains noncompete and nonsolicitation provisions
extending from the commencement of the agreement until two years after the
termination of the agreement.
 
 Stockholders' Agreement
 
  The former stockholders of CSI entered into a stockholders' agreement with
the Company. Under this agreement, the stockholders may not sell, pledge,
encumber, give, bequeath, or otherwise transfer or dispose of the stock
without complying with the terms of the agreements or obtaining the prior
written consent of the Company. A stockholder who receives a qualified offer
(as defined in the agreement) must notify the Company of the offer and the
Company has an option to elect to purchase the stock under the terms contained
in the qualified offer. The stockholders are not required to comply with the
provisions described above in order to effect a sale or disposition of their
stock made in compliance with Securities and Exchange Commission Rule 144.
 
  The stockholders have also entered into employment agreements with CSI as
described above. If the employment of either of the stockholders is terminated
for cause (as defined) or if following the termination of the employment
agreement, the stockholder is determined to have breached any covenants or
restrictions in the

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONCLUDED)
 
employment agreements, the stockholder will offer to sell all of his stock to
the Company. The Company will have an option to elect to purchase the stock at
its then current value price (as defined). If the employment of either of the
stockholders is terminated for a reason other than for cause, excluding
expiration of the employment agreement by its terms, or if the employee
becomes permanently disabled, the stockholder will offer its stock for sale to
the corporation at a price designated by the offering stockholder and the
corporation will have an option to elect to purchase the stock at the offer
price or, if the offering stockholder does not designate a price, the then
current value price (as defined).
 
  In the event that a stockholder dies, the Company will have the option to
purchase and the stockholder's estate will be required to sell all of the
stock at the current value price (as defined). Any Escrowed Stock subsequently
received by a stockholder's estate will be subject to this provision at the
time of earn out.
 
  Under the terms of the stockholders' agreements, the stock may only be
offered for sale, sold or transferred pursuant to an effective registration
under the Securities Act of 1933 or an exemption therefrom. The term of this
restriction is for three years from the date of the agreement, November 6,
1996. The restrictions apply to any additional shares of stock acquired after
the execution of the stockholders' agreement.
 
 Litigation
 
  On April 17, 1997, Alan L. Levine and Canadian American Petroleum
Corporation filed suit in the Third Judicial District Court of Sale Lake
County, Utah against Zmax Corporation, f/k/a Mediterranean Oil Corporation,
f/k/a Oryx Gold Corporation, f/k/a Pandora, Inc. and John Does. The lawsuit
consists of three claims for relief against all of the defendants: civil
conspiracy; wrongful use of civil proceedings; and abuse of process. The
lawsuit seeks unspecified consequential and punitive damages arising from the
alleged delay in the issuance of shares of Common Stock of Pandora, Inc. The
plaintiffs allege that they currently own approximately 64,000 shares of
stock. The lawsuit is currently in the investigative stage. Given the
preliminary stage of this proceeding, the Company has not been able to assess
the relative materiality, or lack, thereof, of the plaintiff's claims. The
Company intends to vigorously defend itself against this action.
 
  The Company is periodically a party to disputes arising from normal business
activities. In the opinion of management, resolution of these matters will not
have a material adverse effect upon the financial position or
future operating results of the Company, and adequate provision for any
potential losses has been made in the accompanying financial statements.

                               AUDITORS' REPORT
 
To the Shareholders,
Mediterranean Oil Corporation
(formerly Oryx Gold Corporation)
 
We have audited the balance sheets of Mediterranean Oil Corporation (formerly
Oryx Gold Corporation) as at December 31, 1994 and 1995 and the statements of
operations, stockholders' equity and cash flows for the years ended December
31, 1993, 1994 and 1995. 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 an audit to obtain
reasonable assurance 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.
 
In our opinion, these financial statements present fairly, in all material
respects, the financial position of the company as at December 31, 1994 and
1995 and the results of its operations and cash flows for the years ended
December 31, 1993, 1994 and 1995 in accordance with generally accepted
accounting principles in the United States.
 
The financial statements as at December 31, 1991 and for the period from
inception, April 24, 1986 to December 31, 1991 were audited by other auditors
who expressed an opinion without reservation on those statements in their
report dated March 12, 1992.

Comments by Auditors for U.S. Readers on Canada - U.S. Reporting Conflict
- ------------------------------------------------------------------------- 

In the United States, reporting standards for auditors require the addition of
an explanatory paragraph (following the opinion paragraph) when there is
substantial doubt about a company's ability to continue as a going concern.
The accompanying financial statements have been prepared on the basis of
accounting principles applicable to a going concern which assumes the
realization of assets and discharge of liabilities in the normal course of
business. As discussed in Note 1 to the accompanying financial statements and
in respect of the company's substantial losses from operations, substantial
doubt about the company's ability to continue as a going concern exists. The
accompanying financial statements do not include any adjustments that might
result from the outcome of this uncertainty.
 
  Our report to the shareholders dated March 28, 1996 is expressed in
accordance with Canadian reporting standards which do not permit a reference
to such uncertainty in the auditors' report when the uncertainty is adequately
disclosed in the financial statements.

opportunities.
 
  These financial statements have been prepared on a going concern basis. The
company has a working capital deficiency of $1,420,020 as at December 31,
1995. The company's ability to continue as a going concern is dependent on the
ability of the company to generate profitable operations in the future and/or
to obtain the necessary financing to meet its obligations and repay its
liabilities arising from normal business operations when they come due.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Organization
 
  The company was incorporated on April 24, 1986 under the laws of the state
of Nevada, U.S.A. under the name Pandora, Inc. On May 4, 1992, the company
changed its name to Oryx Gold Corporation. On November 2, 1995, the company
changed its name to Mediterranean Oil Corporation.
 
 Development Stage Company
 
  The company is a development stage company as defined in Statement of
Financial Accounting Standards No. 7. The company is devoting substantially
all of its present efforts to establish a new business and none of its planned
principal operations have commenced. All losses accumulated since inception
have been considered as part of the company's development stage activities.
 
 Income Taxes
 
  The company used the liability method of accounting for income taxes
pursuant to Statement of Financial Accounting Standards, No. 109 "Accounting
for Income Taxes."
 
 Net Loss Per Share

outstanding during each period.
 
3. INVESTMENT
 
  By an agreement dated April 27, 1992 the company acquired 100% of the shares
of American Oil and Gas Corporation (AOG) for 50,000,000 common shares of the
company, 5,000,000 preferred shares of the company for $5,000 and an
additional 7,061,309 common shares of the company for $7,061. Since April 2,
1992 the preferred shares were never issued and AOG has not undertaken any
business or any financial transactions and is a delinquent corporation. In
addition, on July 21, 1995 the company agreed to cancel the aforementioned
shares (50,000,000 common shares) in return for the assignment of the mining
claims originally held by AOG (At December 31, 1995 these shares had not been
cancelled). Consequently the investment in AOG was written-off.

the State of Delaware (the "Effective Time").
 
  2. Succession; Rights and Liabilities of New ZMAX. At the Effective Time,
New ZMAX will succeed to all of the rights, privileges, powers, immunities and
franchises and all of the property, real, personal and mixed, of Old ZMAX,
without the necessity for any separate transfer. Thereafter, New ZMAX will be
responsible and liable for all liabilities and obligations of Old ZMAX, and
neither the rights of creditors nor any liens on the property of Old ZMAX will
be impaired by the Merger.
 
  3. Common Stock and Preferred Stock of Old ZMAX and New ZMAX. At the
Effective Time, by virtue of the Merger and without any further action on the

shares of Old ZMAX Common Stock to be exchanged for New ZMAX Common Stock
("Old ZMAX Certificate") will cease to have any right as a stockholder of Old
ZMAX. At that time, such holder's sole right will be to receive in exchange
for such holder's Old ZMAX Certificates, on surrender thereof to New ZMAX,
which will act as the exchange agent for Old ZMAX Certificates ("Exchange
Agent"), a certificate or certificates representing the number of whole shares
of New ZMAX that such holder is entitled to receive pursuant to the Merger.
 
    (b) Notwithstanding any other provision of this Merger Agreement, until
  holders or transferees have surrendered Old ZMAX Certificates to the
  Exchange Agent, no dividends will be paid with respect to any shares of Old
  ZMAX Common Stock represented by Old ZMAX Certificates. Such dividends, if
  any, will be paid on surrender of Old ZMAX Certificates. Without regard to
  when such Old ZMAX Certificates are surrendered for exchange as provided
  herein, no interest will be paid on any dividends.

appraisal rights, will be entitled to receive only the value of such shares in
cash as determined pursuant to the applicable provisions of the Nevada Law.

                           ARTICLE IV. CAPITAL STOCK
 
  The aggregate number of shares of stock that the Corporation shall have
authority to issue is sixty million (60,000,000), of which ten million
(10,000,000) shares, with a par value of $0.001 per share, are designated as

    (1) Each holder of Common Stock is entitled to one vote for each share of
  Common Stock standing in such holder's name on the records of the
  Corporation on each matter submitted to a vote of the stockholders, except
  as otherwise required by law.

                                 Stockholders
 
  Section 1.1. Annual Meetings. An annual meeting of stockholders shall be
held for the election of directors on such date, and at such time and place,
either within or without the State of Delaware, as the Board of Directors may
from time to time designate within four months after the end of the fiscal
year of the Corporation. Any other proper business may be transacted at an
annual meeting. If the annual meeting is not held on the date designated, it
may be held as soon thereafter as convenient and shall be called the annual
meeting.
 
  Section 1.2. Special Meetings. Special meetings of the stockholders, for any
purpose or purposes, unless otherwise prescribed by the General Corporation
Law of the State of Delaware, may be called by the President or the Board of
Directors. The President will call a special meeting of the stockholders at
the request of the holders of not less than twenty-five percent (25%) of all
the outstanding shares of the Corporation entitled to vote at the meeting.
 
  Section 1.3. Notice of Meetings. Whenever stockholders are required or
permitted to take any action at a meeting, a written notice of the meeting
will be given that states the place, date and hour of the meeting and, in the
case of a special meeting, the purpose(s) for which the meeting is called.
Unless otherwise provided by law, the Certificate of Incorporation or these
Bylaws, the written notice of any meeting will be given not less than ten nor
more than sixty days before the date of the meeting to each stockholder
entitled to vote at such meeting. If mailed, such notice will be deemed to be
given when deposited in the United States mail, postage prepaid, directed to
the stockholder at his or her address as it appears in the records of the
Corporation.
 
  Section 1.4. Waiver of Notice. A stockholder may waive notice of any
meeting; provided that a stockholder's attendance at meeting shall constitute
waiver of notice of such meeting, except when the stockholder attends a
meeting for the express purpose of objecting to the transaction of any
business to be transacted at the meeting, and not for the purpose of objecting
to the purpose of the meeting.
 
  Section 1.5. Adjournments. Any meeting of stockholders, annual or special,
may adjourn from time to time to reconvene at the same or some other place,
and notice need not be given of any such adjourned meeting if the time and
place are announced at the meeting at which the adjournment is taken. At the
adjourned meeting, the Corporation may transact any business that might have
been transacted at the original meeting. If the adjournment is for more than
thirty days, or if after the adjournment a new record date is fixed for the
adjourned meeting, pursuant to Section 1.3, notice of the adjourned meeting
will be given to each stockholder of record entitled to vote at the meeting.
 
  Section 1.6. Record Date.
 
  (a) Determination of Record Date. For purposes of determining the number and
identity of stockholders for any purpose, the Board of Directors may fix a
date in advance as the record date for any such determination of stockholders,
provided that the record date may not precede the date of the resolution
fixing the record date. The record date may not be more than sixty days prior
to the date that the particular action requiring the determination of
stockholders is to occur. If to determine the stockholders entitled to notice
of, or to vote at, a meeting of stockholders, the record date may not be fewer
than ten days prior to the meeting. The record date for determining
stockholders for any other purpose shall be at the close of business on the
day on which the Board of Directors adopts the resolution relating thereto. A
determination of stockholders of record entitled to notice of, or to vote at,
a meeting of stockholders will apply to any adjournment of the meeting;
provided that the Board of Directors may fix a new record date for the
adjourned meeting.
 
                                      C-1
<PAGE>
 
  (b) Failure to Fix Record Date. If the stock transfer books are not closed
and no record date is fixed for the determination of stockholders entitled to
notice or to vote, or to receive payment of a dividend, the date on which the
notice is mailed or the Board of Directors resolution declaring the dividend
is adopted, as the case may be, will be the record date for such determination
of stockholders.
 
  Section 1.7. List of Stockholders Entitled to Vote. At least ten days before
each meeting of stockholders, the officer or agent charged with overseeing the
stock transfer books of the Corporation will compile a complete list of the
stockholders entitled to vote at such meeting, or any adjournment thereof,
arranged in alphabetical order, with the address of and the number of shares
held by each. Such list will be kept on file at the Corporation's principal
office for the ten days before the meeting and will be subject to the
inspection of any stockholder during that ten-day period during normal
business hours for any purpose related to the meeting and during the meeting.
 
  Section 1.8. Quorum. Except as otherwise provided by law, the Certificate of
Incorporation, or these Bylaws, a majority of the outstanding shares of the
Corporation entitled to vote, represented in person or by proxy, will
constitute a quorum at a meeting of stockholders. If less than a majority of
the outstanding shares are represented at a meeting, a majority of the shares
so represented may adjourn the meeting from time to time without further
notice. If a quorum is present or represented at such adjourned meeting, any
business may be transacted that might have been transacted at the meeting as
originally notified. The stockholders present at a duly organized meeting may
continue to transact business until adjournment, notwithstanding the
withdrawal of enough stockholders to leave less than a quorum.
 
  Section 1.9. Voting.
 
  (a) One Vote Per Share. Unless otherwise provided by the Certificate of
Incorporation or these Bylaws, each outstanding share entitled to vote will be
entitled to one vote on each matter submitted to a vote at a meeting of
stockholders.
 
  (b) Required Vote. Unless the General Corporation Law of the State of
Delaware imposes a super-majority requirement with respect to a particular
matter brought before the stockholders, a majority vote of those shares
present and voting at a duly organized meeting will suffice to defeat or enact
any proposal; provided that with respect to votes to elect directors, a
plurality of the votes cast will be sufficient to elect.
 
  (c) Shares Held By Other Than the Record Owner. Shares held by an
administrator, executor, guardian or conservator may be voted by him or her,
in person or by proxy, without the transfer of such shares into his or her
name. Shares held in the name of a trustee may be voted by him or her, in
person or by proxy, only if the shares are transferred into the trustee's
name. Shares held in the name of, by or under the control of a receiver may be
voted by the receiver without transferring the shares into the receiver's name
if authority to do so is evidenced in an order from the court that appointed
the receiver. A stockholder whose shares are pledged shall be entitled to vote
his or her shares until the shares are transferred into the name of the
pledgee, and thereafter, the pledgee will be entitled to vote the shares so
transferred. Shares belonging to the Corporation or held by it in a fiduciary
capacity may not be voted, directly or indirectly, at any meeting, and will
not be counted in determining the total number of outstanding shares at any
given time.
 
  Section 1.10. Proxies.
 
  (a) General. At all meetings of stockholders, a stockholder may vote by
proxy. Proxies must be written, signed by the stockholder or by his or her
duly authorized attorney-in-fact, and filed with the Secretary of the
Corporation before or at the time of a meeting where a proxy is granted. No
proxy is valid after six months from the date of its execution, unless
otherwise provided in the proxy or coupled with an interest.
 
  (b) Irrevocable Proxies. A proxy may be irrevocable if it states that it is
irrevocable and if, and only as long as, it is coupled with an interest
sufficient in law to support an irrevocable power.

  (c) Revocation of a Proxy. A stockholder may revoke any proxy that is not
irrevocable by attending the meeting and voting in person or by filing an
instrument in writing revoking the proxy of by delivering a proxy in
accordance with applicable law bearing a later date to the Secretary of the
Corporation.

  Section 2.1. Number; Qualifications. The Board of Directors shall consist of
not less than three (3) or more than fifteen (15) members with the specific

next annual meeting of stockholders and until his or her successor is elected
and qualified. Directors need not be stockholders of the corporation.
 
  Section 2.2. Election; Resignation; Vacancies. The Board of Directors will
initially consist of the persons named as director by the incorporator, and
each director so elected will hold office until the first annual meeting of
stockholders and until his or her successor is elected and qualified. At the
first annual meeting of stockholders, the stockholders will elect directors to
serve in all three classes of the Board of Directors as provided by the
Certificate of Incorporation. Thereafter, one class of directors will be
elected each year at either an annual or special meeting of the stockholders
to hold office for the period of time designated for that class. If there is
only one nominee for any directorship, it will be in order to move that the
Secretary cast the elective ballot to elect the nominee. A director may resign
at any time on written notice to the Corporation. Any vacancy occurring in the
Board of Directors, whether by reason of death, resignation, removal, or an
increase in the number of directors, may be filled by the affirmative vote of
the majority of the remaining directors, though less than a quorum of the
Board of Directors, or by election at an annual meeting or at a special
meeting of the stockholders called for that purpose. A director elected to
fill a vacancy will be elected for the unexpired term of his predecessor in
office.
 
  Section 2.3. Regular Meetings. A regular meeting of the Board of Directors
for the election of officers and the transaction of any other business that
may properly come before the meeting shall be held immediately after, and at

directors is then present or as soon thereafter as may be convenient. Regular
meetings of the Board of Directors may be held at such places within or

meeting of the Board of Directors. Notice of a special meeting must be given
to each director by the person(s) calling the meeting at least two days before
the meeting.
 
  Section 2.5. Waiver of Notice. A director may waive notice of any meeting. A
director's attendance at meeting shall constitute waiver of notice of such
meeting; provided that, when a director attends a meeting for the express
purpose of objecting to the transaction of any business to be transacted at
the meeting, and not for the purpose of objecting to the purpose of the
meeting, the director will not be deemed to have waived notice of such
meeting.
 
  Section 2.6. Telephonic Meetings Permitted. Members of the Board of
Directors, or any committee designated by the Board of Directors, may
participate in a meeting thereof by means of telephone conference, or similar
communications equipment that permits all persons participating in the meeting

constitute presence at such meeting.
 
  Section 2.7. Quorum; Voted Required for Action. At all meetings of the Board
of Directors, a majority of the whole Board of Directors will constitute a
quorum for the transaction of business. Unless required by the

Directors. If less than a majority is present at a meeting, a majority of the
directors present may adjourn the meeting from time to time without further
notice. Once a quorum has been established at a duly organized meeting, the
Board of Directors may continue to transact corporate business until
adjournment, notwithstanding the withdrawal of enough members to leave less
than a quorum.
 
  Section 2.8. Payment of Expenses. By resolution of the Board of Directors,
directors may be paid their expenses, if any, of attendance at each meeting of
the Board of Directors. Directors may be paid also either a fixed sum for
attendance at each meeting of the Board of Directors or a stated salary as
director. Such payment will not preclude any director from serving the
Corporation in any other capacity and receiving compensation therefor.
 
  Section 2.9. Dissent to Corporate Action. A director who is present at a
meeting of the Board of Directors at which action on any corporate matter is
taken shall be presumed to have assented to the action taken unless he or she
(i) enters his or her dissent in the minutes of the meeting, (ii) files
written dissent to such action with the Secretary of the meeting before
adjournment, or (iii) expresses such dissent by written notice to the
Secretary of the Corporation within one (1) day after the adjournment of the
meeting. The right to dissent shall not apply to a director who voted in favor
of such action.
 
  Section 2.10. Action by Written Consent. Any action required or permitted to
be taken at a meeting of the Board of Directors may be taken without a meeting
if all members of the Board of Directors sign a written consent with respect
to such action. Such consent shall be filed with the minutes of proceedings of
the Board of Directors.

replace any absent or disqualified member at any meeting of the committee. In
the absence or disqualification of a member of the committee, the member or
members thereof present at any meeting and not disqualified from voting,
whether or not constituting a quorum, may unanimously appoint another member
of the Board of Directors to act at the meeting in place of any such absent or
disqualified member. Any such committee, to the extent permitted by the
General Corporation Law of the State of Delaware and to the extent provided in
the resolution of the Board of Directors, will have and may exercise all the
powers and authority of the Board of Directors in the management of the
business and affairs of the Corporation, and may authorize the seal of the
Corporation to be affixed to all papers that may require it.
 
  Section 3.2. Committee Rules. Unless the Board of Directors otherwise
provides, each committee designated by the Board of Directors may make, alter

rules, each committee will conduct its business in the same manner as the
Board of Directors conducts its business pursuant to Article II of these
Bylaws.

  Section 6.1. Directors
 
  (a) Right to Indemnification; Insurance. Every person who was or is a party
to, or is threatened to be made a party to, or is involved in any action, suit
or proceeding, whether civil, criminal, administrative or investigative, by
reason of the fact that he or she, or a person of whom he is the legal
representative, is or was a director, or is or was serving at the request of
the corporation as a director, officer, employee or agent of another
corporation, or as its representative in another enterprise (an "Indemnitee"),
will be indemnified and held harmless by the Corporation to the fullest extent
legally permissible under the laws of the State of Delaware against all
judgments, fines, penalties, excise taxes, amounts paid in settlement and
costs, charges and expenses (including attorneys' fees and disbursements)
actually and reasonably incurred or suffered by him or her in connection
therewith, subject to the standards of conduct, the procedures, and other
applicable provisions of the General Corporation Law of the State of Delaware.
Such right of indemnification is a contract right which may be enforced in any
manner desired by such person. The corporation may purchase and maintain
insurance on behalf of an Indemnitee against any liability arising out of such
status, whether or not the corporation would have the power to indemnify such
person.
 
  (b) Inurement. The right to indemnification shall inure whether or not the
claim asserted is based on matters that predate the adoption of this Article
VIII, will continue as to an Indemnitee who has ceased to hold the position by
virtue of which he or she was entitled to indemnification, and will inure to
the benefit of his or her heirs and personal representatives.
 
  (c) Non-exclusivity of Rights. The right to indemnification and to the
advancement of expenses conferred by this Section 6.1 are not exclusive of any
other rights that an Indemnitee may have or acquire under any statute, bylaw,
agreement, vote of stockholders or disinterested directors, this Certificate
of Incorporation or otherwise.
 
  (d) Advancement of Expenses. The Corporation will, from time to time,
reimburse or advance to any Indemnitee the funds necessary for payment of
expenses, including attorneys' fees and disbursements, incurred in connection
with defending any proceeding for which he or she is indemnified by the
Corporation, in advance of the final disposition of such proceeding; provided
that, if then required by the General Corporation Law of the State of
Delaware, the expenses incurred by or on behalf of an Indemnitee may be paid
in advance of the final disposition of a proceedings only upon receipt by the
Corporation of an undertaking by or on behalf of such Indemnitee to repay any
such amount so advanced if it is ultimately determined by a final and
unappealable judicial decision that the Indemnitee is not entitled to be
indemnified for such expenses.
 
  Section 6.2. Officers, Employees and Agents. The Board of Directors may, on
behalf of the Corporation, grant indemnification to any officer, employee,
agent or other individual to such extent and in such manner as the Board of
Directors in its sole discretion may from time to time and at any time
determine, in accordance with the General Corporation Law of the State of
Delaware.

provided in NRS 92A.470, within 30 days after receipt of a demand for payment,
the subject corporation shall pay each dissenter who complied with NRS 92A.440
the amount the subject corporation estimates to be the fair value of his
shares, plus accrued interest. The obligation of the subject corporation under
this subsection may be enforced by the district court:
 
    (a) Of the county where the corporation's registered office is located;
  or
 
    (b) At the election of any dissenter residing or having its registered

  2. The payment must be accompanied by:
 
    (a) The subject corporation's balance sheet as of the end of a fiscal

  92A.480; and
 
    (e) A copy of NRS 92A.300 to 92A.500, inclusive.
 
  92A.470 Payment for Shares: Shares Acquired on or After Date of Dissenter's
Notice.--1. A subject corporation may elect to withhold payment from a
dissenter unless he was the beneficial owner of the shares before the date set
forth in the dissenter's notice as the date of the first announcement to the
news media or to the stockholders of the terms of the proposed action.
 
  2. To the extent the subject corporation elects to withhold payment, after
taking the proposed action, it shall estimate the fair value of the shares,
plus accrued interest, and shall offer to pay this amount to each dissenter
who agrees to accept it in full satisfaction of his demand. The subject
corporation shall send with its offer a statement of its estimate of the fair
value of the shares, an explanation of how the interest was calculated, and a
statement of the dissenters' right to demand payment pursuant to NRS 92A.480.
 
                                      D-4
<PAGE>
 
  92A.480 Dissenter's Estimate of Fair Value: Notification of Subject
Corporation; Demand for Payment of Estimate.--1. A dissenter may notify the
subject corporation in writing of his own estimate of the fair value of his
shares and the amount of interest due, and demand payment of his estimate,
less any payment pursuant to NRS 92A.460, or reject the offer pursuant to NRS
92A.470 and demand payment of the fair value of his shares and interest due,
if he believes that the amount paid pursuant to NRS 92A.460 or offered
pursuant to NRS 92A.47 is less than the fair value of his shares or that the
interest is incorrectly calculated.
 
  2. A dissenter waives his right to demand payment pursuant to this section
unless he notifies the subject corporation of his demand in writing within 30
days after the subject corporation made or offered payment for his shares.
 
  92A.490 Legal Proceeding to Determione Fair Value: Duties of Subject
Corporation; Powers of Court; Rights of Dissenter.--1. If a demand for payment
remains unsettled, the subject corporation shall commence a proceeding within
60 days after receiving the demand and petition the court to determine the
fair value of the shares and accrued interest. If the subject corporation does
not commence the proceeding within the 60-day period, it shall pay each
dissenter whose demand remains unsettled the amount demanded.
 
  2. A subject corporation shall commence the proceeding in the district court
of the county where its registered office is located. If the subject
corporation is a foreign entity without a resident agent in the state, it
shall commence the proceeding in the county where the registered office of the
domestic corporation merged with or whose shares were acquired by the foreign
entity was located.
 
  3. The subject corporation shall make all dissenters, whether or not
residents of Nevada, whose demands remain unsettled, parties to the proceeding
as in an action against their shares. All parties must be served with a copy
of the petition. Nonresidents may be served by registered or certified mail or
by publication as provided by law.
 
  4. The jurisdiction of the court in which the proceeding is commenced under
subsection 2 is plenary and exclusive. The court may appoint one or more
persons as appraisers to receive powers described in the order appointing
them, or any amendment thereto. The dissenters are entitled to the same
discovery rights as parties in other civil proceedings.
 
  5. Each dissenter who is made a party to the proceeding is entitled to a
judgment:
 
    (a) For the amount, if any, by which the court finds the fair value of
  his shares, plus interest, exceeds the amount paid by the subject
  corporation; or
 
    (b) For the fair value, plus accrued interest, of his after-acquired
  shares for which the subject corporation elected to withhold payment
  pursuant to NRS 92A.470.
 
  92A.500 Legal Proceeding to Determine Fair Value: Assessment of Costs and
Fees.--1. The court in a proceeding to determine fair value shall determine
all of the costs of the proceeding, including the reasonable compensation and
expenses of any appraisers appointed by the court. The court shall assess the
costs against the subject corporation, except that the court may assess costs
against all or some of the dissenters, in amounts the court finds equitable,
to the extent the court finds the dissenters acted arbitrarily, vexatiously or
not in good faith in demanding payment.
 
  2. The court may also assess the fees and expenses of the counsel and
experts for the respective parties, in amounts the court finds equitable:
 
    (a) Against the subject corporation and in favor of all dissenters if the
  court finds the subject corporation did not substantially comply with the
  requirements of NRS 92A.300 to 92A.500, inclusive; or
 
    (b) Against either the subject corporation or a dissenter in favor of any
  other party, if the court finds that the party against whom the fees and
  expenses are assessed acted arbitrarily, vexatiously or not in good faith
  with respect to the rights provided by NRS 92A.300 to 92A.500, inclusive.
 
                                      D-5
<PAGE>
 
  3. If the court finds that the services of counsel for any dissenter were of
substantial benefit to other dissenters similarly situated, and that the fees
for those services should not be assessed against the subject corporation, the
court may award to those counsel reasonable fees to be paid out of the amounts
awarded to the dissenters who were benefited.
 
  4. In a proceeding commenced pursuant to NRS 92A.460, the court may assess
the costs against the subject corporation, except that the court may assess
costs against all or some of the dissenters who are parties to the proceeding,
in amounts the court finds equitable, to the extent the court finds that such
parties did not act in good faith in instituting the proceeding.
 
  5. This section does not preclude any party in a proceeding commenced
pursuant to NRS 92A.460 or 92A.490 from applying the provisions of N.R.C.P. 68
or NRS 17.115.

                    INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Set forth below is a description of certain provisions of the Old ZMAX
Articles of Incorporation, Old ZMAX Bylaws and Nevada Law, as well as the New
ZMAX Certificate of Incorporation, New ZMAX Bylaws and Delaware Law, as such
provisions relate to the indemnification of the directors and officers of Old
and New ZMAX. These descriptions are intended only as a summary and are
qualified in their entirety by reference to the complete documents.
 
 Elimination of Liability in Certain Circumstances
 
  OLD ZMAX. Article XI of the Old ZMAX Articles of Incorporation provides that
no director or officer of Old ZMAX is personally liable to Old ZMAX or its
stockholders with respect to any acts or omissions that occur in the
performance of his or her duties as a director or officer of Old ZMAX, except
liability for acts or omissions involving (i) intentional misconduct, fraud or
a violation of law, or (ii) payment of distributions in violation of Section
78.300 of the Nevada Law, which imposes liability on directors for prohibited
distributions to stockholders. The Old ZMAX Articles of Incorporation further
provide that, if the Nevada Law is amended to extend further protection to
officers or directors, then the stockholders may approve further limitations
on liability in the Articles of Incorporation to the full extent of the Nevada
Law. The Company is not permitted under the Nevada Law to limit the liability
of directors for (i) any breach of the director's duty of loyalty to such
corporation or its stockholders, or (ii) any transaction from which the
director derived an improper personal benefit.
 
  NEW ZMAX. As of the Effective Time, the New ZMAX Certificate of
Incorporation will provide that, to the full extent permitted by Delaware Law
or any other applicable laws, no director of New ZMAX shall be personally
liable to New ZMAX or its stockholders with respect to any acts or omissions
in the performance of his or her duties as a director of Old ZMAX. The
Delaware Law provides that a corporation may limit or eliminate a director's
personal liability for monetary damages to the corporation or its
stockholders, except for liability for (i) any breach of the director's duty
of loyalty to such corporation or its stockholders, (ii) acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation
of law, (iii) paying a dividend or approving a stock repurchase in violation
of Section 174 of the Delaware Law or (iv) any transaction from which the
director derived an improper personal benefit.
 
 Indemnification and Insurance
 
  OLD ZMAX. Section 78.751 of the Nevada Law permits corporations to indemnify
directors, officers, employees and agents (including individuals acting in
that capacity for another corporation at the request of the indemnifying
corporation) for expenses incurred in connection with any proceeding, as long
as the individual acted "in good faith and in a manner which he reasonably
believed to be in or not opposed to the best interests of the corporation,
and, with respect to any criminal action or proceeding, had no reasonable
cause to believe his conduct was unlawful." An adverse result against an
indemnitee does not necessarily determine that indemnification is not
available. Indemnification is permitted even though the individual no longer
serves in the appropriate capacity, as long as he or she was serving in that
capacity when the conduct occurred. To the extent that an individual is
successful in defending against a claim subject to indemnification, the
corporation must indemnify him or her for the expense of the defense. A
corporation may advance expenses of pursuing a proceeding giving rise to a
right of indemnification, if the individual agrees to repay such expenses if
indemnification ultimately is denied.
 
  The determination to pay a claim for indemnification must be made by either
(i) the stockholders, (ii) majority vote of the board of directors of a quorum
consisting of directors who were not a party to the proceeding; (iii) by legal
opinion, if ordered by a majority as described in (ii) above; or (iv) by legal
opinion, if a majority described in (ii) cannot be obtained.
 
                                     II-1
<PAGE>
 
  The Old ZMAX Articles of Incorporation provision on indemnification closely
follows the Nevada Law. Article XII of the Old ZMAX Articles of Incorporation
provides that the Company will indemnify its directors, officers, employees
and agents (as well as persons serving at the Corporation's request as an
director, officer, employee or agent of another entity) if they are made a
party (or threatened with being made a party) to any proceeding because of
their status as a director, officer, employee or agent. This indemnification
applies whether the alleged basis for such proceeding is action taken in an
official capacity or an unofficial capacity. Article XII specifically provides
that these individuals are indemnified to the fullest extent permitted by the
Nevada Law against all expense, liability and loss, including attorneys' fees,
judgments, fines, ERISA excise taxes or penalties and amounts paid in
settlement, that are reasonably incurred in connection with the proceeding.
Further, under the Old ZMAX Articles of Incorporation, an indemnitee remains
indemnified for acts taken while serving as a director, office, employee or
agent even though the indemnitee no long serves in that capacity. If the
proceeding is initiated by the indemnitee against the Corporation, Article XII
provides for indemnification only if the Board of Directors authorized the
proceeding.
 
  Indemnitees are entitled to advancement of expenses to defend proceedings
where they are subject to indemnification. Article XII further provides that,
if the Nevada Law requires, indemnified directors and officers must, as a
condition of receiving an advancement of expenses, agree to repay the advanced
expenses if ultimately it is found that the indemnitee is not entitled to
indemnification for such expenses.
 
  If the Corporation does not pay claims for indemnification within 60 days,
the indemnitee may sue the Corporation to recover the unpaid amount of the
claim. If the claim is for advancement of expenses, the indemnitee may sue the
Corporation is the claim remains unpaid for 20 days, and if the indemnitee is
successful in a suit for a claim of advancement of expenses, the indemnitee is
entitled to the cost of prosecuting the action to recover expenses. In any
suit against the Corporation for indemnification, except a suit for
advancement of expenses, the Corporation may raise the defense that the
indemnitee's conduct did not meet the standard of the Nevada Law. The
Corporation has the burden of proof in any suit brought to enforce rights of
indemnification against the Corporation, including suits for advancement of
expenses.
 
  NEW ZMAX. Similar to the Nevada Law, the Delaware Law permits corporations
to indemnify directors and officers as well as other employees and individuals
against expenses (including attorneys' fees), judgments, fines and amounts
paid in settlement in connection with specified actions, suits or proceedings,
whether civil, criminal, administrative or investigative (other than an action
by or in the right of the corporation) if they acted in good faith and in a
manner they reasonably believed to be in, or not opposed to, the best interest
of the corporation, and with respect to any criminal action or proceeding, had
no reasonable cause to believe their conduct was unlawful. However, different
from the Nevada Law, Delaware corporations may not indemnify against any
claim, issue or matter as to which the indemnified person is adjudged liable
to the corporation, unless, and only to the extent that, the Delaware Court of
Chancery (or the court in which such action or suit was brought) determines
upon application that, despite the adjudication of liability, but in view of
all the circumstances of the case, the indemnified person is fairly and
reasonably entitled to indemnity for such expenses, which the Delaware Court
of Chancery or such other court deems proper.
 
  As of the Effective Time, the New ZMAX Certificate of Incorporation will
indemnify the directors, officer, employees, agents of New ZMAX to the fullest
extent permitted by the Delaware Law, or any other applicable law. Similar to
the Old ZMAX Articles of Incorporation, the New ZMAX Certificate of
Incorporation will provide indemnification for the same range of costs and
expenses, will permit advancement of expenses, and will permit indemnitees the
same rights to sue to recover indemnified amounts.

ITEM 22. UNDERTAKINGS.
 
  Insofar as indemnification of liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Co-Registrants pursuant to the foregoing provisions, or otherwise, the Co-
Registrants have been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by either Co-
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Co-Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Co-Registrant will,
unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.
 
  The undersigned Co-Registrants hereby undertake to supply by means of a
post-effective amendment all information concerning a transaction, and the

                            STOCK PURCHASE AGREEMENT

     THIS STOCK PURCHASE AGREEMENT (this "Agreement") is entered into on
November 6, 1996, among ZMAX Corporation, a Nevada corporation ("ZMAX"); and
Michael S. Cannon, a resident of the Commonwealth of Virginia, and Michael C.
Higgins, a resident of the State of Maryland, being the holders of all the
issued and outstanding capital stock of Century Services, Inc., a Maryland
corporation ("CSI") (individually, a "Stockholder" and collectively, the
"Stockholders").

                                  BACKGROUND:

     All of the issued and outstanding capital stock consisting of 200 shares of
voting common stock, par value $1.00, of CSI (the "CSI Stock") is owned by the
Stockholders.

     The Stockholders have agreed to sell to ZMAX and ZMAX has agreed to
purchase the CSI Stock from the Stockholders on the terms and conditions set
forth in this Agreement.

     In consideration of the mutual representations, warranties, covenants and
agreements contained in this Agreement, the parties agree as follows:

                              STATEMENT OF TERMS:

                                   SECTION 1
                           PURCHASE AND SALE OF STOCK

     1.1  Purchase and Sale of Stock.  Stockholders will sell to ZMAX and ZMAX
          --------------------------                                          
will purchase from Stockholders all of the Stockholders' right, title and
interest in the CSI Stock.

     1.2  Consideration; Stock Exchange.  At the Closing (as defined in Section
          -----------------------------                                        
2.1 below), upon surrender of the certificates evidencing the CSI Stock duly
endorsed for transfer to ZMAX, ZMAX will cause 3,200,000 shares of the common
voting stock, par value $0.001 of ZMAX (the "ZMAX Stock") (the "Consideration")
to be issued to the Stockholders pursuant to Section 1.5 of this Agreement.  As
a result of the sale of the CSI Stock and the payment of the Consideration, CSI
will be a wholly-owned subsidiary of ZMAX.

     1.3  Issuance of ZMAX Stock to Stockholders.  At the Closing, each
          --------------------------------------                       
Stockholder will receive stock certificates evidencing 200,000 shares of ZMAX
Stock.  In addition, ZMAX will issue to each Stockholder a stock certificate
evidencing 1,400,000 shares of ZMAX Stock (collectively, the "Earn Out Stock"),
which Earn Out Stock will be placed in escrow pursuant to the escrow agreement
attached as Exhibit A to this Agreement (the "Earn Out Stock Escrow Agreement")
            ---------                                                          
and will be released to the Stockholders on the terms and conditions set forth
in Section 1.5.
<PAGE>
 
     1.4  No Further Ownership Rights in CSI Stock.  The issuance of the 400,000
          ----------------------------------------                              
shares of ZMAX Stock to be delivered to the Stockholders at Closing and the
issuance of the 2,800,000 shares of Earn Out Stock to be released to the
Stockholders in accordance with the terms of this Agreement will be deemed to
have been given in full satisfaction of all rights pertaining to the CSI Stock.

     1.5  Release of Earn Out Stock; Terms of Earn Out.  The 2,800,000 shares of
          --------------------------------------------                          
Earn Out Stock will be subject to release quarterly.  The Earn Out Stock will be
released to the Stockholders on a pro rata basis to each Stockholder.  One share
of Earn Out Stock will be released for each $1.25 of Cash Flow (as defined
below) generated by CSI.  For purposes of this Section 1.5, the term "Cash Flow"
means, with respect to each CSI fiscal year quarter or other period, all
operating revenues from sales and services and licensing and franchising income
(but excluding proceeds from loans or capital infusions and proceeds from sales,
exchanges and other dispositions of property or rights not in the ordinary
course of business) LESS direct operating expenses including software licensing
fees and a provision for CSI's income taxes calculated based on the then-
applicable statutory rates (but excluding capital expenses, depreciation,
amortization, debt service, dividends and intercompany charges other than
charges that would be direct operating expenses if paid by CSI).  Cash Flow will
be determined by Arthur Andersen (or such other independent accounting firm then
serving CSI) for the relevant period on a cash basis.  ZMAX will cause Arthur
Andersen to prepare a statement of Cash Flow ("Cash Flow Statement") for each
fiscal year quarter which will set forth an itemized calculation of Cash Flow
and calculate the number of shares of Earn Out Stock (to the nearest whole
number of shares) based on the Cash Flow for the relevant period and to deliver
the Cash Flow Statement to ZMAX.  Upon receipt of the Cash Flow Statement, ZMAX
will fax the Cash Flow Statement to each Stockholder.  Upon approval of the Cash
Flow Statement as evidenced by the signing of the Cash Flow Statement by both
ZMAX and each Stockholder, ZMAX will deliver the Cash Flow Statement to the
escrow agent under the Earn Out Stock Escrow Agreement.  Upon receipt of the
signed Cash Flow Statement, the escrow agent will cause the shares of Earn Out
Stock to be released to the Stockholders in accordance with the procedures
described in the Earn Out Stock Escrow Agreement.  Once released from the Earn
Out Stock Escrow Agreement such shares will no longer be deemed Earn Out Stock
for purposes of this Agreement.

     1.6  Resolution of Disputes Regarding Cash Flow.  If ZMAX and the
          ------------------------------------------                  
Stockholders cannot agree on the Cash Flow Statement prepared by the independent
accounting firm for any quarter, the ZMAX Board of Directors will prepare and
sign a Cash Flow Statement and fax it to the Stockholders.  If the ZMAX Board of
Directors' Cash Flow Statement is approved by the Stockholders, as evidenced by
the signature of the Stockholders, ZMAX will submit it to the escrow agent under
the Earn Out Stock Escrow Agreement.  If the Stockholders are not satisfied with
the Cash Flow Statement prepared by the ZMAX Board of Directors (the "Dispute"),
the Stockholders may submit the Dispute to binding arbitration administered by
the American Arbitration Association ("AAA") under its Commercial Arbitration
Rules, except where those rules are supplemented or modified by the express
terms of this section.  The parties agree that binding arbitration is the
exclusive remedy for resolving any Dispute.  The Stockholders may initiate
arbitration by sending notice of its intention to arbitrate the Dispute to ZMAX,
which

                                      -2-
<PAGE>
 
notice must be accompanied by a brief setting forth the nature of the Dispute
and the remedy sought, which brief may not exceed 25 typed pages (the
"Arbitration Notice").  The Stockholders must also file at the regional office
of the AAA three copies of the Arbitration Notice and Brief and the arbitration
provision of this Agreement together with the required filing fee.  ZMAX must
file a responsive brief within 15 business days of receipt of the Stockholders'
Arbitration Notice and Brief, which responsive brief may not exceed 25 typed
pages.  Any arbitration proceedings will be in Washington, D.C.  If the parties
are able to agree on one arbitrator within 15 days of the date the Arbitration
Notice is filed with the AAA, the Dispute will be heard by that arbitrator.  If
the parties are unable to agree on one arbitrator, then an arbitrator will be
selected from an impartial roster of arbitrators provided by the AAA in
accordance with the AAA rules.  There will be no discovery permitted by the
parties in the arbitration proceedings provided that each party will be
permitted to take one oral deposition of the other party or unless otherwise
mutually agreed to by the parties.  ZMAX agrees to be bound by Rule 30(b)(6) of
the Federal Rules of Civil Procedures "Deposition of an Organization," as
amended from time to time or any successor rule.  The arbitrator will issue a
decision within 30 days of his or her appointment.  The decision of the
arbitrator must set forth in reasonable detail the reasoning supporting the
decision of the arbitrator.  The decision rendered by the arbitrator will be
final and binding on the parties and judgment on the decision rendered by the
arbitrator may be entered in any court having jurisdiction.  Each party will pay
its own costs and expenses related to the arbitration procedures.  This
agreement to arbitrate is specifically enforceable under the prevailing
arbitration law and survives the termination of this Agreement.

     1.7  Termination of Rights to Earn Out Stock.  If any Stockholder is
          ---------------------------------------                        
terminated by CSI for cause (as defined in the Stockholder's employment
agreement with CSI) or violates the non-competition, non-solicitation or
proprietary information restrictions in his employment agreement with CSI, the
Earn Out Stock issued in the name of the Stockholder will automatically
terminate and will be returned to ZMAX in accordance with the procedures
described in the Earn Out Stock Escrow Agreement.

     1.8  Voting Rights to Earn Out Stock.  The Stockholders will be entitled to
          -------------------------------                                       
vote the Earn Out Stock even though it is subject to the Earn Out Stock Escrow
Agreement on the following terms and conditions.  If an annual or special
meeting of the ZMAX Stockholders is called, the Stockholders will be entitled to
receive notice of such meeting and to attend such meeting and vote all of the
shares of ZMAX stock issued in their name, including the Earn Out Stock, in
person or by proxy.

     1.9  Dividend and Distribution Rights for Earn Out Stock.  The Stockholders
          ---------------------------------------------------                   
are entitled to receive dividends or other distributions made by ZMAX (including
distributions in liquidation) on the Earn Out Stock.

     1.10  Antidilution.  ZMAX agrees that so long as CSI has entered into three
           ------------                                                         
contracts to provide quantifiable services related to the resolution of the
"Year 2000 problem" involving at least 1,000,000 lines of code per contract with
United States government agencies or

                                      -3-
<PAGE>
 
government agencies of any state and/or commercial companies within 60 days of
the date of this Agreement, the percentage holdings of ZMAX represented by the
ZMAX Stock issued to the Stockholders will not be less than 34.2% (assuming the
Stockholders earn all of the Earn Out Stock) after giving effect to the
1,000,000 shares of ZMAX Stock to be issued in connection with the $5,000,000
private placement contemplated by ZMAX but without taking into account any
future purchases of newly issued ZMAX Stock, if any.

     1.11  Use of Private Placement Proceeds.  ZMAX agrees that $4,000,000 of
           ---------------------------------                                 
the $5,000,000 private placement referred to in Section 1.10 will be earmarked
for working capital of CSI and will be released to CSI as needed based on
operational budgets of CSI approved by the ZMAX Board of Directors, from time to
time, taking into account business needs.

to ZMAX.  All such agreements are in full force and effect and, there are no
existing material defaults or events of default, real or claimed, or events
which with or without notice or lapse of time or both would constitute material
defaults under such agreements that would give the non-defaulting party a right

amendments to such CSI Leases.  Each CSI Lease is in full force and effect and
there is no default asserted thereunder by any party thereto and, to the
Stockholders' knowledge, there are no unasserted defaults (including any events
which with the passage of time or giving of notice or both would constitute a
default).  True, correct and complete copies of all the CSI Leases, as amended

and operation of any of the real properties leased by CSI does not conform to
applicable building, zoning, safety, environmental, and other laws, ordinances,

furniture, fixtures and other tangible personal property and assets necessary
for the continued operation of the business of CSI as presently conducted and
where the absence of such property and assets would have a CSI Material Adverse
Effect.  All of such personal properties are in good operating condition (normal
wear and tear excepted), and are reasonably fit for the purposes for which the
such personal property is presently used.

     3.14 Compliance with Law.  To the knowledge of the Stockholders, CSI holds

registrations and authorizations necessary for the conduct of its business or
the ownership of its properties or assets, except where the failure to hold or
comply could not have a CSI Material Adverse Effect, and all of such permits,
certificates, licenses, approvals, registrations, and authorizations are in full
force and effect.  To the knowledge of the Stockholders, CSI is in compliance
with all applicable laws, statutes, ordinances, rules and regulations (including
without limitation those relating to environmental protection, occupational
safety and health, and equal employment practices) and all orders, judgments and
decrees, except where the failure to comply would not have a CSI Material
Adverse Effect.

for such taxes reflected in the CSI Reference Balance Sheet are sufficient to
satisfy the accrued liability for such taxes as of the date of the CSI Reference
Balance Sheet.  No material tax issues have been raised by the Internal Revenue
Service in connection with any of the tax returns referred to above, and no
waivers of statutes of limitations or extensions of time within which to file
any tax return or with respect to a tax assessment or deficiency have been given
or requested with respect to CSI.

     3.16 Labor Relations.  None of CSI's employees is represented by any union

                          SURVIVAL AND INDEMNIFICATION

     5.1  Survival of Representations and Warranties.  The representations,
          ------------------------------------------                       
warranties and covenants made by the parties shall survive the Closing for a
period of 9 months from the Closing Date; provided, however, that
representations and warranties relating to taxes will survive for a period of
five years after the Closing Time or until the expiration date of the statute of
limitations applicable to such tax liability or the final determination of any
such tax liability, including the final administrative or judicial determination
thereof, whichever occurs first.

     5.2  Indemnification by Stockholders.  The Stockholders, jointly and
          -------------------------------                                
severally, agree to indemnify ZMAX and CSI, and their respective officers,
directors, shareholders, employees, agents and affiliates (other than the
Stockholders themselves) in respect of, and hold each of them harmless from and
against, any and all damages, fines, fees, penalties, deficiencies, losses and
expenses (including without limitation interest, court costs, fees of attorneys,
accountants and other experts or other expenses of litigation or other
proceedings or of any claim, default or assessment) suffered, incurred or
sustained by any of them or to which any of them becomes

                                      -15-
<PAGE>
 
subject, resulting from, arising out of or relating to any misrepresentation,
breach of warranty or nonfulfillment of or failure to perform any covenant or
agreement on the part of the Stockholders contained in this Agreement.

     5.3  Indemnification by ZMAX.  ZMAX agrees to indemnify the Stockholders in
          -----------------------                                               
respect of, and hold each of them harmless from and against, any and all
damages, fines, fees, penalties, deficiencies, losses and expenses (including
without limitation interest, court costs, fees of attorneys, accountants and
other experts or other expenses of litigation or other proceedings or of any
claim, default or assessment) suffered, incurred or sustained by any of them or
to which any of them becomes subject, resulting from, arising out of or relating
to any misrepresentation, breach of warranty or nonfulfillment of or failure to
perform any covenant or agreement on the part of ZMAX contained in this
Agreement.

     5.4  Procedures for Indemnification for Third Party Claims.  Whenever
          -----------------------------------------------------           
indemnification is sought under this Section 5 in connection with a claim or
demand brought by a third party, the party seeking indemnification (the
"Indemnitee") will promptly notify the party from whom indemnification is sought
(the "Indemnitor"), specifying the nature of such claims, the amount or
estimated amount of such claim and attaching copies of all relevant information
concerning the underlying claim of liability.  Within ten days of receipt of
such notice, the Indemnitor will notify the Indemnitee promptly whether it
disputes its indemnification obligation.  If the indemnification obligation is
not so disputed, the Indemnitor, at the option of the Indemnitee, will, at the
Indemnitor's cost and expense, defend any such claim.  If the Indemnitee so
elects for the Indemnitor to defend any claim, the Indemnitor will have full
control over the conduct of such proceeding, although the Indemnitee will have
the right to retain legal counsel at its own expense and will have the right to
approve any settlement of any claim, provided that such approval may not be
withheld unreasonably.  If the Indemnitee does not elect for the Indemnitor to
assume the defense of such claim, the Indemnitee will have the right to defend
the claim at the reasonable cost and expense of the Indemnitor.  The Indemnitor
will not be obligated to indemnify the Indemnitee with respect to such third
party claim to the extent that the Indemnitor's ability to defend has been
irreparably prejudiced by the failure or delay of the Indemnitee to give
Indemnitor the notice required by this Section 6.3.  Any dispute of an
indemnification obligation under this Agreement may be resolved by litigation in
a court of competent jurisdiction.

     5.5  Procedures for Indemnification for Non-Third Party Claims.  If any
          ---------------------------------------------------------         
Indemnitee has a claim under Section 5 against any Indemnitor that does not
involve a third party claim as described in Section 5.4 above, the Indemnitee
will promptly notify the Indemnitor of such claim, specifying the nature of such
claim and the amount of any loss incurred by the Indemnitee.  The failure by any
Indemnitee to give such notice will not impair such party's rights under this
Agreement except to the extent that the Indemnitor demonstrates that it has been
irreparably prejudiced thereby.  If the Indemnitor notifies the Indemnitee that
it does not dispute the claim described in such notice or fails to notify the
Indemnitee within 30 days its receipt of such notice, the loss in the amount
specified in the notice will be conclusively deemed a liability of the
Indemnitor under Section 5 and the Indemnitor will pay the amount of

                                      -16-
<PAGE>
 
such loss to the Indemnitee on demand.  If the Indemnitor has timely disputed
its liability with respect to such claim, the Indemnitor and the Indemnitee will
proceed in good faith to negotiate a resolution of such dispute, and if not
resolved through negotiations within 60 days after the Indemnitors receipt of
the initial claim notice, such dispute may be resolved by litigation in a court
of competent jurisdiction.

     5.6  Security for Indemnification.  As security for their indemnification
          ----------------------------                                        
obligations under this Section 5, the Stockholders, effective as of the Closing
Date, agree to pledge their ZMAX Stock in favor of ZMAX by executing the stock
pledge agreement in substantially the form of the Stock Pledge and Security
Agreement attached as Exhibit F to this Agreement (the "Stock Pledge
                      ---------                                     
Agreement").

     5.7  Indemnification for Fees and Commissions.  Each party to this
          ----------------------------------------                     
Agreement is responsible for paying any broker, finder or investment banker that
is entitled to receive any brokerage, finder's or other fee or commission in
connection with the transactions contemplated by this Agreement based upon
arrangements made by or on behalf of such party and indemnifies and holds
harmless the other parties from any such fees or commissions.


                                   SECTION 6
                            MISCELLANEOUS PROVISIONS

     6.1  Worldwide Software Rights.  The Stockholders will use their best
          -------------------------                                       
efforts to obtain for CSI an option to purchase the balance of the worldwide
rights to the COCAT software.

     6.2  Actions by Stockholders.  Any action or remedy of the Stockholders
          -----------------------                                           
under this Agreement, including without limitation, a request for arbitration or
indemnification, must be exercised jointly by the Stockholders.

     6.3  Effectiveness of Representations.  Each party is entitled to rely on
          --------------------------------                                    
the representations, warranties and agreements of each of the other parties and
all such representation, warranties and agreement will be effective regardless
of any investigation that any party has undertaken or failed to undertake.

the amount of the subscription price has been paid in, shall not be subject to

     VIII.  TERM OF EXPERIENCE.  This corporation shall have perpetual
            ------------------                                        
existence.

     IX.  CUMULATIVE VOTING.  No cumulative voting shall be permitted in the
          -----------------                                                 
election of directors.

     X.   PREEMPTIVE RIGHTS:  Stockholders shall not be entitled to preemptive

rights.

     XI.  LIMITATION OF LIABILITY OF OFFICERS AND DIRECTORS:  Any director or
          -------------------------------------------------                  
officer of the Corporation shall not be personally liable to the Corporation or
its stockholders for damages for breach of fiduciary duty as a director or
officer except for liability:

          (i) arising from acts or omissions which involve intentional
     misconduct, fraud or a knowing violation of law; or

          (ii) arising from the payment of distributions in violation of Nevada
                                                                         ------
Revised Statutes, Section 78.300.
- ----------------                 

     If the Nevada General Corporation Law is amended after approval by the
stockholders of this section further eliminating or limiting the personal
liability of officers or directors, then the liability of an officer or a
director of the Corporation shall be eliminated to the fullest extent permitted
by the Nevada General Corporation Law, as so amended.

                                       5
<PAGE>
 
     Any repeal or modification of the foregoing paragraph by the stockholders
of the Corporation shall not adversely affect any right or protection of an
officer or a director of the Corporation existing at the time of such repeal or
modification.

     XII. INDEMNIFICATION
          ---------------

     (a) Right to Indemnification.  Each person who was or is made a party or is
         ------------------------                                               
threatened to be made a party to or is otherwise involved in any action, suit or
proceeding, whether civil, criminal, administrative or investigative
(hereinafter a "proceeding"), by reason of the fact that he or she is or was a
director, officer or employee of the Corporation or is or was serving at the
request of the Corporation as a director, officer, employee or agent of another
corporation or of a partnership, joint venture, trust or other enterprise,
including service with respect to employee benefit plans (hereinafter an
"indemnitee"), whether the basis of such proceeding is alleged action in an
official capacity as a director, officer, employee or agent or in any other
capacity while serving as a director, officer, employee or agent, shall be
indemnified and held harmless by the Corporation to the fullest extent
authorized by the Nevada General Corporation Law, as the same exists or may
hereafter be amended (but, in the case of any such amendment, only to the extent
that such amendment permits the Corporation to provide broader indemnification
rights that such law permitted the Corporation to provide prior to such
amendment), against all expense, liability and loss (including attorneys' fees,
judgments, fines, ERISA excise taxes or penalties and amounts paid in
settlement) reasonably incurred or suffered by such indemnitee in connection
therewith and such indemnification shall continue as to an indemnitee who has
ceased to be a director, officer, employee or agent and shall inure to the
benefit of the indemnitee's heirs,

                                       6
<PAGE>
 
executors and administrators; provided, however, that, except as provided in
paragraph (b) hereof with respect to proceedings to enforce rights to
indemnification, the Corporation shall indemnify any such indemnitee in
connection with a proceeding (or part thereof) initiated by such indemnitee only
if such proceeding (or part thereof) was authorized by the Board of Directors of
the Corporation.  The right to indemnification conferred in this section shall
be a contract right and shall include the right to be paid by the Corporation
the expenses incurred in defending any such proceeding in advance of its final
disposition (hereinafter an "advancement of expenses"); provided, however, that,
if the Nevada General Corporation Law requires, an advancement of expenses
incurred by an indemnitee in his or her capacity as a director or officer (and
not in any other capacity in which service was or is rendered by such
indemnitee, including, without limitation, service to an employee benefit plan)
shall be made only upon delivery to the Corporation of an undertaking, by or on
behalf of such indemnitee, to repay all amounts so advanced if it shall
ultimately be determined by final judicial decision from which there is no
further right to appeal that such indemnitee is not entitled to be indemnified
for such expenses under this section or otherwise (hereinafter an
"undertaking").

     (b) Right of Indemnitee to Bring Suit.  If a claim under paragraph (a) of
         ---------------------------------                                    
this section is not paid in full by the Corporation within sixty days after a
written claim has been received by the Corporation, except in the case of a
claim for an advancement of expenses, in which case the applicable period shall
be twenty days, the indemnitee may at any time thereafter bring suit against the
Corporation to recover the unpaid amount of the claim.  If successful in whole
or in part in any such suit or in a suit brought by the Corporation to

                                       7
<PAGE>
 
recover an advancement of expenses pursuant to the terms of an undertaking, the
indemnitee shall be entitled to be paid also the expense of prosecuting or
defending such sit.  In (i) any suit brought by the indemnitee to enforce a
right to indemnification hereunder (but not in a suit brought by the indemnitee
to enforce a right to an advancement of expenses) it shall be a defense that,
and (ii) any suit by the Corporation to recover an advancement of expenses
pursuant to the terms of an undertaking the Corporation shall be entitled to
recover such expense upon a final adjudication that, the indemnitee has not met
the applicable standard of conduct set forth in the Nevada General Corporation
Law.  Neither the failure of the Corporation (including its Board of Directors,
independent legal counsel, or its stockholders) to have made a determination
prior to the commencement of such suit that indemnification of the indemnitee is
proper in the circumstances because the indemnitee has met the applicable
standard of conduct set forth in the Nevada General Corporation Law, nor an
actual determination by the Corporation (including its Board of Directors,
independent legal counsel, or its stockholders) that the indemnitee has not met
such applicable standard of conduct, shall create a presumption that the
indemnitee has not met the applicable standard of conduct or, in the case of
such a suit brought by the indemnitee, be a defense to such suit.  In any suit
brought by the indemnitee to enforce a right hereunder, or by the Corporation to
recover an advancement of expenses pursuant to the terms of an undertaking, the
burden of proving that the indemnitee is not entitled to be indemnified or to
such advancement of expenses under this section or otherwise shall be on the
Corporation.

     (c) Non-Exclusivity of Rights.  The rights to indemnification and to the
         -------------------------                                           
advancement of expenses conferred in this section shall not be exclusive of any
other rights

                                       8
<PAGE>
 
which any person may have or hereafter acquire under any statute, bylaw,
agreement, vote of stockholders or disinterested directors, the Articles of
Incorporation or otherwise.

     (d) Insurance.  The Corporation may maintain insurance, at its expense, to
         ---------                                                             
protect itself and any director, officer, employee or agent of the Corporation
or another corporation, partnership, joint venture, trust or other enterprise
against any expense, liability or loss, whether or not the Corporation would
have the power to indemnify such person against such expense, liability or loss
under the Nevada General Corporation Law.

     (e) Indemnification of Agents of the Corporation.  The Corporation may, to
         --------------------------------------------                          
the extent authorized from time to time by the Board of Directors, grant rights
to indemnification and to the advancement of expenses, to any agent of the
Corporation to the fullest extent of the provisions of this section with respect
to the indemnification and advancement of expenses of directors, officers and
employees of the Corporation.

                                 Stockholders
                                 ------------

Section 1:  The annual meeting of the stockholders shall be held in July of each
- ---------                                                                       
year, at a date and time to be specified by the Board of Directors.  Said
meeting shall be for the purpose of electing directors for the ensuing year and
for the transaction of such other directors as may come before the meeting.  If
the election of directors shall not be held on the day designated for the annual
meeting of the stockholders, or at any adjournment thereof, the Board of
Directors shall cause the election to be held at a special meeting of the
stockholders as soon thereafter as possible.

Section 2:  Special meetings of the stockholders, for any purpose or purposes,
- ---------                                                                     
unless otherwise prescribed by Statute, may be called by the President or by the
Board of Directors and shall be called by the President at the request of the
holders of not less than one-tenth of all the outstanding shares of the
corporation entitled to vote at the meeting.

Section 3:  The Board of Directors may designate any place within or without the
- ---------                                                                       
State of Nevada as the site for any annual or special stockholders meeting.  A
waiver of notice signed
<PAGE>
 
by all stockholders entitled to vote at a meeting may designate any place,
either within or without the State of Nevada, as the site for any meeting
hereinabove authorized.  If no designation is made, the place of the meeting
shall be at the principal office of the corporation in the State of Nevada.

Section 4:  Written or printed notice stating the site, date and time of the
- ---------                                                                   
meeting and, in case of a special meeting, the purpose or purposes for which the
meeting is called, shall be delivered not less than ten (10) days nor more than
sixty (60) days before the date of the meeting, either personally or by mail, by
or at the direction and over the signature of the President, or the Secretary,
or the officer or person calling the meeting, to each stockholder of record
entitled to vote at such meeting.  If mailed, such notice shall be deemed to be
delivered when deposited in the United States mail, addressed to the stockholder
at his address as it appears on the stock transfer books of the corporation,
with postage thereon prepaid.

Section 5:  For the purpose of determining stockholders entitled to notice of or
- ---------                                                                       
to vote at any meeting of stockholders, or any adjournment thereof, or
stockholders entitled to receive payment of any dividend, or in order to make a
determination of stockholders for any other proper purpose, the Board of
Directors of the corporation may provide that the stock transfer books shall be
closed for a stated period, not to exceed twenty (20) days.  In lieu of closing
the stock transfer books, the Board of Directors may fix in advance a date as
the record date for any such determination of stockholders, such date in any
case to be not more than sixty (60) days and, in case of a meeting of
stockholders, not less than fifteen (15) days prior to the date which the
particular action requiring such determination of stockholders is to be taken.
If the stock transfer books are not closed and no record dates fixed for the
determination of stockholders entitled to notice of or to vote, or entitled to
receive payment of a dividend, the date on which notice of the meeting is mailed
or the date on which the resolution of the Board of Directors declaring such
dividend is adopted, as the case may be, shall be the record date for such
determination of stockholders.  When a determination of stockholders entitled to
vote at any meeting of stockholders has been made as provided in this section,
such determination shall apply to any adjournment thereof, except where the
determination has been made through the closing of the stock transfer books and
the stated period of closing has expired.

Section 6:  The officer or agent having charge of the stock transfer books for
- ---------                                                                     
share of the corporation shall make, at least ten (10) days before each meeting
of stockholders, a complete list of the stockholders entitled to vote at such
meeting, or any adjournment thereof, arranged in alphabetical order, with the
address of, and the number of shares held by, each, which list, for a period of
ten (10) days prior to such meeting, shall be kept on file at the principal
office of the corporation and shall be subject to the inspection of any
stockholder during the meeting.

Section 7:  A majority of the outstanding shares of the corporation entitled to
- ---------                                                                      
vote, represented in person or by proxy, shall constitute a quorum at a meeting
of stockholders.  If

                                       2
<PAGE>
 
less than a majority of the outstanding shares are represented at a meeting, a
majority of the shares so represented may adjourn the meeting from time to time
without further notice. At such adjourned meeting at which a quorum shall be
present or represented, any business may be transacted which might have been
transacted at the meeting as originally notified.  The stockholders present at a
duly organized meeting may continue to transact business until adjournment,
notwithstanding the withdrawal of enough stockholders to leave less than a
quorum.

Section 8:  At all meetings of stockholders, a stockholder may vote by proxy
- ---------                                                                   
which shall be executed in writing by the stockholder or by his duly authorized
attorney in fact.  Such proxy shall be filed with the Secretary of the
corporation before or at the time of the meeting.  No proxy shall be valid after
six (6) months from the date of its execution, unless otherwise provided in the
proxy or coupled with an interest.

Section 9:  Each outstanding share otherwise entitled to vote shall be entitled
- ---------                                                                      
to one (1) vote upon each matter submitted to a vote at a meeting of
stockholders.  A majority vote of those shares present and voting at a duly
organized meeting shall suffice to defeat or enact any proposal unless the
Statutes of the State of Nevada require a greater-than-majority vote, in which
event the higher vote shall be required for the action to constitute the action
of the corporation.

Section 10:  Shares hold by an administrator, executor, guardian or conservator
- ----------                                                                     
may be voted by him, either in person or by proxy, without the transfer of such
shares into his name.  Shares standing in the name of a trustee may be voted by
him, either in person or by proxy, but no trustee shall be entitled to vote
shares held by him without transfer of such shares into his name.

Shares standing in the name of a receiver may be voted by such receiver, and
shares held by or under the control of a receiver may be voted by such receiver
without the transfer thereof into his name if authority to do so be contained in
an appropriate order of the Court by which such receiver was appointed.

A stockholder whose shares are pledged shall be entitled to vote such shares
until the shares are transferred into the name of the pledgee, and thereafter
the pledgee shall be entitled to vote the shares so transferred.

Shares of its own stock belonging to the corporation or held by it in a
fiduciary capacity shall not be voted, directly or indirectly, at any meeting,
and shall not be counted in determining the total number of outstanding shares
at any given time.

Section 11:  An action required to be taken at a meeting of the stockholders, or
- ----------                                                                      
any other action which may be taken at a meeting of the stockholders, may be
taken without a meeting, if a consent in writing, setting forth the action so
taken, shall be signed by a majority of the stockholders entitled to vote with
respect to the subject matter thereof, unless a greater-than-

                                       3
<PAGE>
 
majority vote would be required at a duly organized meeting, in which event said
greater-than-majority stockholder approval must be obtained.  Such consent shall
be filed with the Minutes of Proceedings.

Section 12:  The following order of business shall be observed at all meetings
- ----------                                                                    
of the stockholders, so far as practicable:

          (a)  Calling the roll;

          (e)  Election of Directors;

          (f)  Unfinished business;

          (g)  Now business; and

          (h)  Adjournment.

more than eleven (11) members with the specific number to be set from time to

performance of his or her duties as a director of the Corporation.  Any
amendment or repeal of this Article VIII will not adversely affect any right or
protection of a director of the Corporation with respect to any act or omission
occurring before such amendment or repeal.


                         Article IX.  Indemnification

          (a)  Right to Indemnification.  Any person who was or is a party, or
               ------------------------                                       
is threatened to be made a party, to any threatened, pending, or completed
proceeding, whether civil, criminal, administrative, or investigative (whether
or not by or in the right of the Corporation) by reason of the fact that he or
she is or was a director of the Corporation (or is or was serving at the request
of the Corporation as a director of another entity) is entitled to be
indemnified by the Corporation (an

                                  Page 2 of 3
<PAGE>
 
"Indemnitee") to the full extent then permitted by law against judgments, fines,
penalties, excise taxes, amounts paid in settlement and costs charges and
expenses (including attorneys' fees and disbursements) that he or she incurs in
connection with such proceeding.  The right to indemnification will continue as
to an Indemnitee who has ceased to hold the position by virtue if which he or
she was entitled to indemnification, and will inure to the benefit of his or her
heirs and personal representatives.

          (b)  Advancement of Expenses.  The Corporation will, from time to
               -----------------------                                     
time, reimburse or advance to any Indemnitee the funds necessary for payment of
expenses, including attorneys' fees and disbursements, incurred in connection
with defending any proceeding for which he or she is indemnified by the
Corporation, in advance of the final disposition of such proceeding; provided
that, if then required by the Delaware General Corporation Law, the expenses
incurred by or on behalf of an Indemnitee may be paid in advance of the final
disposition of a proceedings only upon receipt by the Corporation of an
undertaking by or on behalf of such director or officer to repay any such amount
so advanced if it is ultimately determined by a final and unappealable judicial
decision that the Indemnitee is not entitled to be indemnified for such
expenses.


        Article X.  Action by Unanimous Written Consent of Stockholders

          Any action that is required or permitted to be taken by the

                                     BYLAWS

                              NEW ZMAX CORPORATION


                                   ARTICLE I

                                  Stockholders

          Section 1.1.  Annual Meetings.  An annual meeting of stockholders
shall be held for the election of directors at such date, time and place, either
within or without the State of Delaware, as the Board of Directors may from time
to time direct by resolution.  Any other proper business may be transacted at an
annual meeting.

          Section 1.2.  Special Meetings.  Special meetings of the stockholders,
for any purpose or purposes, unless otherwise prescribed by the General
Corporation Law of the State of Delaware, may be called by the President or the
Board of Directors.  The President will call a special meeting of the
stockholders at the request of the holders of not less than twenty-five percent
(25%) of all the outstanding shares of the Corporation entitled to vote at the
meeting.

          Section 1.3.  Notice of Meetings.  Whenever stockholders are required
or permitted to take any action at a meeting, a written notice of the meeting
will be given that states the place, date and hour of the meeting and, in the
case of a special meeting, the purpose(s) for which the meeting is called.
Unless otherwise provided by law, the Certificate of Incorporation or these
Bylaws, the written notice of any meeting will be given not less than ten nor
more than sixty days before the date of the meeting to each stockholder entitled
to vote at such meeting.  If mailed, such notice will be deemed to be given when
deposited in the United States mail, postage prepaid, directed to the
stockholder at his or her address as it appears in the records of the
Corporation.

          Section 1.4.  Waiver of Notice.  A stockholder may waive notice of any
meeting; provided that a stockholder's attendance at a meeting shall constitute
waiver of notice of such meeting, except when the stockholder attends a meeting
for the express purpose of objecting to the transaction of any business to be
transacted at the meeting, and not for the purpose of objecting to the purpose
of the meeting.

          Section 1.5.  Adjournments.  Any meeting of stockholders, annual or
special, may adjourn from time to time to reconvene at the same or some other
place, and notice need not be given of any such adjourned meeting if the time
and place are announced at the meeting at which the adjournment is taken.  At
the adjourned meeting, the Corporation may transact any business that might have
been transacted at the original meeting.  If the adjournment is for more than
<PAGE>
 
thirty days, or if after the adjournment a new record date is fixed for the
adjourned meeting, pursuant to Section 1.3, notice of the adjourned meeting will
be given to each stockholder of record entitled to vote at the meeting.

          Section 1.6.  Record Date.

          (a)  Determination of Record Date.  For purposes of determining the
number and identity of stockholders for any purpose, the Board of Directors may
fix a date in advance as the record date for any such determination of
stockholders, provided that the record date may not proceed the date of the
resolution fixing the record date.  The record date may not be more than sixty
days prior to the date that the particular action requiring the determination of
stockholders is to occur.  If to determine the stockholders entitled to notice
of or to vote at a meeting of stockholders, the record date may not be fewer
than ten days prior to the meeting. The record date for determining stockholders
for any other purpose shall be at the close of business on the day on which the
Board of Directors adopts the resolution relating thereto. A determination of
stockholders of record entitled to notice of or to vote at a meeting of
stockholders will apply to any adjournment of the meeting; provided that the
Board of Directors may fix a new record date for the adjourned meeting.

          (b)  Failure to Fix Record Date.  If the stock transfer books are not
closed and no record date is fixed for the determination of stockholders
entitled to notice or to vote, or to receive payment of a dividend, the date on
which the notice is mailed or the Board of Directors resolution declaring the
dividend is adopted, as the case may be, will be the record date for such
determination of stockholders.

          Section 1.7.  List of Stockholders Entitled to Vote.  At least ten
days before each meeting of stockholders, the officer or agent charged with
overseeing the stock transfer books of the Corporation will compile a complete
list of the stockholders entitled to vote at such meeting, or any adjournment
thereof, arranged in alphabetical order, with the address of and the number of
shares held by each.  Such list will be kept on file at the Corporation's
principal office for the ten days before the meeting and will be subject to the
inspection of any stockholder during that ten-day period during normal business
hours for any purpose related to the meeting and during the meeting.

          Section 1.8.  Quorum.  Except as otherwise provided by law, the
Certificate of Incorporation or these Bylaws, a majority of the outstanding
shares of the Corporation entitled to vote, represented in person or by proxy,
will constitute a quorum at a meeting of stockholders.  If less than a majority
of the outstanding shares are represented at a meeting, a majority of the shares
so represented may adjourn the meeting from time to time without further notice.
If a quorum is present or represented at such adjourned meeting, any business
may be transacted that might have been transacted at the meeting as originally
notified.  The

                                     - 2 -

<PAGE>
 
stockholders present at a duly organized meeting may continue to transact
business until adjournment, notwithstanding the withdrawal of enough
stockholders to leave less than a quorum.

          Section 1.9.  Voting.

          (a)  One Vote Per Share.  Unless otherwise provided by the Certificate
of Incorporation or these Bylaws, each outstanding share entitled to vote will
be entitled to one vote on each matter submitted to a vote at a meeting of
stockholders.

          (b)  Required Vote.  Unless the Delaware General Corporation Law
imposes a super-majority requirement with respect to a particular matter brought
before the stockholders, a majority vote of those shares present and voting at a
duly organized meeting will suffice to defeat or enact any proposal; provided
that with respect to votes to elect directors, a plurality of the votes cast
will be sufficient to elect .

          (c)  Shares Held By Other Than the Record Owner.  Shares held by an
administrator, executor, guardian or conservator may be voted by him or her, in
person or by proxy, without the transfer of such shares into his or her name.
Shares held in the name of a trustee may be voted by him or her, in person or by
proxy, only if the shares are transferred into the trustee's name.  Shares held
in the name of, by or under the control of a receiver may be voted by the
receiver without transferring the shares into the receiver's name if authority
to do so is evidenced in an order from the court that appointed the receiver. A
stockholder whose shares are pledged shall be entitled to vote his or her shares
until the shares are transferred into the name of the pledgee, and thereafter,
the pledgee will be entitled to vote the shares so transferred.  Shares
belonging to the Corporation or held by it in a fiduciary capacity may not be
voted, directly or indirectly, at any meeting, and will not be counted in
determining the total number of outstanding shares at any given time.

          Section 1.10.  Proxies.

          (a)  General.  At all meetings of stockholders, a stockholder may vote
by proxy.  Proxies must be written, signed by the stockholder or by his or her
duly authorized attorney-in-fact, and filed with the Secretary of the
Corporation before or at the time of a meeting where a proxy is granted.  No
proxy is valid after six months from the date of its execution, unless otherwise
provided in the proxy or coupled with an interest.

          (b)  Irrevocable Proxies.  A proxy may be irrevocable if it states
that it is irrevocable and if, and only as long as, it is coupled with an
interest sufficient in law to support an irrevocable power.

          (c)  Revocation of a Proxy.  A stockholder may revoke any proxy that
is not irrevocable by attending the meeting and voting in person or by filing an
instrument in writing revoking the

                                     - 3 -
<PAGE>
 
proxy of by delivering a proxy in accordance with applicable law bearing a later
date to the Secretary of the Corporation.

          Section 2.1.  Number; Qualifications.  The Board of Directors shall
consist of not less than two (2) or more than eleven (11) members with the
specific number to be set from time to time by the affirmative vote of a
majority of the members of the Board of Directors.  A director will hold office
until the next annual meeting of stockholders and until his or her successor is
elected and qualified.  Directors need not be stockholders of the corporation.

          Section 2.2.  Election; Resignation; Vacancies.  The Board of
Directors will initially consist of the persons named as director by the
incorporator, and each director so elected will hold office until the first
annual meeting of stockholders and until his or her successor is elected and
qualified.  A director may resign at any time on written notice to the
Corporation.  Any vacancy occurring in the Board of Directors, whether by reason
of death, resignation, removal, or an increase in the number of directors, may
be filled by the affirmative vote of the majority of the remaining directors,
though less than a quorum of the Board of Directors, or by election at an annual
meeting or at a special meeting of the stockholders called for that purpose.  A
director elected to fill a vacancy will be elected for the unexpired term of his
predecessor in office.

          Section 2.3.  Regular Meetings.  Regular meetings of the Board of
Directors may be held at such places within or without the State of Delaware and
at such times as the Board of Directors may from time to time determine.  The
Board of Directors may provide, by resolution, the day, time and place for the
holding of additional regular meetings without other notice than such
resolution.  A regular meeting of the Board of Directors shall be held
immediately after, and at the same place as, each annual meeting of
stockholders.

          Section 2.4.  Special Meetings.  Special meetings of the Board of
Directors may be called by or at the request of the President or any director.
The person(s) authorized to call special meetings of the Board of Directors may
fix any place, within or without the State of Delaware, to hold a special
meeting of the Board of Directors.  Notice of a special meeting must be given by
the person(s) calling the meeting at least two days before the meeting.

          Section 2.5.  Waiver of Notice.  A director may waive notice of any
meeting.  A director's attendance at a meeting shall constitute waiver of notice
of such meeting; provided that, when a director attends a meeting for the
express purpose of objecting to the transaction of any business to be transacted
at the meeting, and not for the purpose of objecting to the purpose of the
meeting, the director will not be deemed to have waived notice of such meeting.

          Section 2.6.  Telephonic Meetings Permitted.  Members of the Board of
Directors, or any committee designated by the Board of Directors, may
participate in a meeting thereof by means of telephone conference, or similar
communications equipment that permits all persons participating in the meeting
to hear each other, and participation in a meeting pursuant to this By-law will
constitute presence at such meeting.

          Section 2.7.  Quorum; Voted Required for Action.  At all meetings of
the Board of Directors, a majority of the whole Board of Directors will
constitute a quorum for the transaction of business.  Unless required by the
Delaware General Corporation Law, the Certificate of Incorporation or these
Bylaws, the vote of a majority of the directors present at a meeting at which a
quorum is present will be the act of the Board of Directors.  If less than a
majority is present at a meeting, a majority of the directors present may
adjourn the meeting from time to time without further notice.  Once a quorum has
been established at a duly organized meeting, the Board of Directors may
continue to transact corporate business until adjournment, notwithstanding the
withdrawal of enough members to leave less than a quorum.

          Section 2.8.  Payment of Expenses.  By resolution of the Board of
Directors, directors may be paid their expenses, if any, of attendance at each
meeting of the Board of Directors.  Directors may be paid also either a fixed
sum for attendance at each meeting of the Board of Directors or a stated salary
as director.  Such payment will not preclude any director from serving the
Corporation in any other capacity and receiving compensation therefor.

          Section 2.9.  Dissent to Corporate Action.  A director who is present
at a meeting of the Board of Directors at which action on any corporate matter
is taken shall be presumed to have assented to the action taken unless he or she
(i) enters his or her dissent in the minutes of the meeting, (ii) files written
dissent to such action with the Secretary of the meeting before adjournment, or
(iii) expresses such dissent by written notice to the Secretary of the
Corporation within one (1) day after the adjournment of the meeting.  The right
to dissent shall not apply to a director who voted in favor of such action.

          Section 2.10.  Action by Written Consent.  Any action required or
permitted to be taken at a meeting of the Board of Directors may be taken
without a meeting if all members of the Board of Directors sign a written
consent with respect to such action.  Such consent shall be filed with the
minutes of proceedings of the Board of Directors.

                                   Committees

          Section 3.1.  Committees.  The Board of Directors may, by resolution
passed by a majority of the whole Board of Directors, designate one or more
committees, each to consist of one or more of the directors.  The Board of
Directors may designate one or more directors as

member at any meeting of the committee.  In the absence or disqualification of a
member of the committee, the member or members thereof present at any meeting
and not disqualified from voting, whether or not constituting a quorum, may
unanimously appoint another member of the Board of Directors to act at the
meeting in place of any such absent or disqualified member.  Any such committee,
to the extent permitted by law and to the extent provided in the resolution of
the Board of Directors, will have and may exercise all the powers and authority
of the Board of Directors in the management of the business and affairs of the
Corporation, and may authorize the seal of the Corporation to be affixed to all
papers that may require it.

          Section 3.2.  Committee Rules.  Unless the Board of Directors
otherwise provides, each committee designated by the Board of Directors may
make, alter and repeal rules for the conduct of its business.  In the absence of
such rules, each committee will conduct its business in the same manner as the
Board of Directors conducts its business pursuant to Article II of these Bylaws.

elected and qualified, or until his or her death, resignation or removal.

arising out of such status, whether or not the corporation would have the power
to indemnify such person.

exchange or Conversion of this Debenture in accordance with the terms hereof
will be rounded down to the nearest whole share and the principal amount of this
Debenture allocated to any fractionalized share will be returned to the Holder.

                             COMMON STOCK WARRANT
                                      of
                               ZMAX CORPORATION

Date:  ______________________________

     THIS CERTIFIES that, for value received _________________________________
(the "Warrantholder") is entitled, upon the terms and subject to the conditions
set forth herein, to purchase from ZMAX CORPORATION, a Nevada corporation (the
"Company"), __________________________ (______) shares of the common stock, par
value $0.001 (the "Common Stock") of the Company (the "Shares") at the purchase
price per share of $7.00, if exercised prior to the first anniversary of the
date of this Warrant, or $8.00 per share if exercised thereafter (the "Exercise
Price").  The number of shares and Exercise Price are subject to adjustment as
provided below.

     This Warrant is being issued to the Warrantholder in connection with the
exchange of a certain Subordinated Exchangeable Debenture held by the
Warrantholder and is subject to the following terms and conditions:

     1.   Exercise of Warrant.  This Warrant may be exercised in whole or in
          -------------------                                               
part, at any time, or from time to time, after the date hereof and on or before
the second anniversary of the date hereof by the surrender of this Warrant and
the Notice of Exercise annexed hereto (duly completed and executed on behalf of
the Warrantholder) to the Company and by the payment of the Exercise Price for
the Shares to be purchased by the Warrantholder to the Company by cash or check
acceptable to the Company.  The Company will prepare a certificate for the
Shares purchased and, if this Warrant is exercised in part, a new Warrant for
the unexercised portion of this Warrant.  The Company agrees that, upon exercise
of this Warrant in accordance with the terms hereof, the Shares so purchased
will be deemed to be issued to the Warrantholder as the record owner of such
Shares as of the close of business on the date on which this Warrant was
exercised.

     If the Company reasonably determines that registration under the Securities
Act of 1933, as amended (the "Act"), is required or that the Warrantholder has
failed to provide the Company with such information as may be necessary to
establish an exemption from the registration requirements under the Act, the
Company may defer the exercise of this Warrant until either a registration
statement under the Act has been declared effective or the Warrantholder has
provided information satisfactory to the Company that establishes the
availability of an exemption from the registration requirements under the Act.

     Certificates for Shares purchased under this Warrant and, on partial
exercise of this Warrant, a new Warrant for the unexercised portion of this
Warrant will be delivered to the Warrantholder or as such Warrantholder may
direct as promptly as practicable after the date on which this Warrant
<PAGE>
 
was exercised.  The Company covenants that all Shares that may be issued upon
the exercise of rights represented by this Warrant will, upon exercise of the
rights represented by this Warrant and payment of the Exercise Price, be fully
paid and nonassessable.

     With the consent of the Company, which consent with not be unreasonably
withheld, and subject to applicable laws and regulations, the Warrantholder may
direct that the certificates for Shares purchased under this Warrant be issued
in name or names other than the name of the Warrantholder.  In this case, this
Warrant when surrendered for exercise must be accompanied by the Assignment Form
attached hereto duly executed by the Warrantholder and the Notice of Exercise
duly completed and executed and stating in whose name or names certificates are
to be issued.

     2.   Reservation of Shares; No Impairment or Amendment.  The Company will
          -------------------------------------------------                   
at all times reserve and keep available, solely for issuance, sale and delivery
upon the exercise of this Warrant, a number of shares of Common Stock equal to
the number of shares of Common Stock issuable upon the exercise of this Warrant.
The Company will not by any amendment of its Articles of Incorporation or
through any other means, avoid or seek to avoid the observance or performance of
any of the terms of this Warrant.

     3.   Expiration.  This Warrant, if not exercised by Warrantholder, will
          ----------                                                        
expire on the second anniversary of the date hereof.

     4.   Adjustments of Exercise Price and Number of Shares Purchasable.  The
          --------------------------------------------------------------      
Exercise Price and the number of shares purchasable under this Warrant is
subject to adjustment from time to time in accordance with the following
provisions:

          (a) Reorganization, Consolidation or Merger.  If at any time there is
              ---------------------------------------                          
a reorganization, consolidation or merger of the Company with or into another
corporation or entity when the Company is not the surviving entity, or the
transfer of all or substantially all of its properties or assets to any other
person or entity under any plan or arrangement contemplating the dissolution of
the Company, then in each such case, the Company, or such successor entity, as
the case may be, will execute a new Warrant providing that the Warrantholder
will have the right to exercise such new Warrant and, upon such exercise, to
receive, in lieu of each share issuable upon exercise of this Warrant, the
number and kind of shares of stock, other securities, money or property
receivable upon such reorganization, consolidation or merger by a holder of the
number of shares then purchasable with this Warrant.  Such new Warrant will
contain provisions relating to the rights and obligations of the Warrantholder
and the Company after such reorganization, consolidation or merger that will
have, as nearly as possible after appropriate adjustment, the same effect as the
provisions of this Warrant, including the provisions of this Warrant relating to
the exercise price and number and type of shares of stock deliverable upon
exercise.

          (b) Reclassification, etc.  If the Company, at any time, by
              ----------------------                                 
subdivision, combination or reclassification of securities or otherwise, changes
any of the securities as to which purchase rights under this Warrant exist into
the same or a different number of securities of any other class or classes, this
Warrant will thereafter represent the right to acquire such number and kind of
securities as would have been issuable as the result of such change with respect
to the

                                      -2-
<PAGE>
 
securities which were subject to the purchase rights under this Warrant
immediately prior to such subdivision, combination, reclassification or other
change.

          (c) Certain Dividends.  If the Company at any time while this Warrant
              -----------------                                                
is outstanding and unexpired pays a dividend (other than dividends out of
retained earnings), or make any other distribution with respect to Common Stock
payable in stock (other than Common) or other securities or property, then the
Company will provide by resolution of the Company's Board of Directors that on
exercise of this Warrant, the Warrantholder will receive, in addition to the
shares of Common Stock otherwise receivable on exercise hereof, the same number
and kind of stock, other securities and property which the Warrantholder would
have received had the Warrantholder held the shares of Common Stock receivable
on exercise hereof on and before the record date for such dividend or
distribution.

          (d) Adjustment to Exercise Price.  The Exercise Price will be
              ----------------------------                             
proportionately adjusted based on any adjustment to the number of Shares
purchasable hereunder following the date of this Warrant.

     5.   Notice of Adjustment; Notices.  Whenever the Exercise Price or number
          -----------------------------                                        
of shares purchasable hereunder will be adjusted, the Company at its expense
will promptly issue a certificate signed by an executive officer of the Company
setting forth, in reasonable detail, the event requiring the adjustment, the
amount of the adjustment, the method by which such adjustment was calculated and
the Exercise Price and number of shares purchasable hereunder after giving
effect to such adjustment, and will cause a copy of such certificate to be sent
to the Warrantholder.

     6.   No Fractionalized Shares.  No fractionalized shares of Common Stock or
          ------------------------                                              
other security will be issued upon exercise of this Warrant.  The shares of
Common Stock or other security issued to the Warrantholder as a result of any
exercise of this Warrant in accordance with the terms hereof will be rounded
down to the nearest whole share.

     7.   Transfer of Warrant.  This Warrant and all rights hereunder are
          -------------------                                            
transferable, in whole or in part, but only with the prior written consent of
the Company, which consent will not be unreasonably withheld.  In order to
transfer this Warrant, the Warrantholder must deliver to the Company this
Warrant together with the Assignment Form annexed hereto properly endorsed.
Upon receipt thereof, the Company will affect such transfer as promptly as
practicable.

     8.   No Voting Rights, Etc.  Prior to the proper exercise of this Warrant,

the Warrantholder, as such, is not entitled to vote or receive dividends or be
deemed to be a shareholder of the Company for any purposes, nor may anything
contained in this Warrant be construed to confer such rights upon Warrantholder.

     9.   Registry of Warrant.  The Company will maintain a registry showing the
          -------------------

                              NOTICE OF EXERCISE

To:  ZMAX Corporation


     1.   The undersigned hereby elects to purchase __________________ shares of
Common Stock ("Stock") of ZMAX Corporation (the "Company") pursuant to the terms
of the attached Warrant, and tenders herewith payment of the purchase price,
together with an Investment Representation Statement (see attached form) in form
and substance satisfactory to legal counsel to the Company.

     2.   The shares of Stock to be received by the undersigned upon exercise of
the Warrant are being acquired for its own account, not as a nominee or agent,
and not with a view to resale or distribution of any part thereof, and the
undersigned has no present intention of selling, granting any participation in,
or otherwise distributing the same.  The undersigned further represents that it
does not have an contract, undertaking, agreement or arrangement with any person
to sell, transfer or grant participation to such person or to any third person,

information it considers necessary or appropriate for deciding whether to
purchase the Stock.

     3.   The undersigned understands that the shares of Stock and the shares of
the Company's Common Stock into which the Stock is convertible are characterized

are being acquired from the Company in transactions not involving a public
offering and that under such laws and applicable regulations such securities may
be resold without registration under the Securities Act of 1933, as amended (the
"Act"), only in certain limited circumstances.  In this connection, the

Act, as presently in effect, and understandings the resale limitations imposed
thereby and by the Act.

Regulation D under the Act or is not a "U.S. Person" as defined in Rule 902
regulations under the Act.

     ACT OF 1933, AS AMENDED.  THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED,

          (b) Any legend required by applicable state law.

                      INVESTMENT REPRESENTATION STATEMENT


PURCHASER:     _______________________________________

COMPANY:       ZMAX Corporation

SECURITIES:    Warrant to purchase _____________ shares of Common Stock

DATE:          _____________________


In connection with the purchase of the above-listed Securities, the undersigned,
the Purchaser, represents to the Company the following:

          (a) The undersigned is sufficiently aware of the Company's business
affairs and financial condition to reach an informed and knowledgeable decision
to acquire the Securities.  The undersigned is purchasing these Securities for
its own account for investment purposes only and not with a view to, or for the
resale in connection with, any "distribution" thereof for purposes of the
Securities Act of 1933, as amended (the "Securities Act").

          (b) The undersigned understands that the Securities have not been
registered under the Securities Act in reliance upon a specific exemption
therefrom, which exemption depends upon, among other things, the bona fide
nature of its investment intent as expressed herein.  In this connection, the
undersigned understands that, in the view of the Securities and Exchange
Commission (the "SEC"), the statutory basis for such exemption may be
unavailable if its representation was predicated solely upon a present intention
to hold these Securities for the minimum capital gains period specified under
tax statutes for a deferred sale, for or until an increase or decrease in the
market price of the Securities, or for a period of one year or any other fixed
period in the future.

          (c) The undersigned further understands that the Securities must be
held indefinitely unless subsequently registered under the Securities Act or
unless an exemption from registration is otherwise available (such as Rule 144
under the Securities Act).  In addition, the undersigned understands that the
certificate evidencing the Securities may be imprinted with a legend which
prohibits the transfer of the Securities unless they are registered or such
registration is not required in the opinion of counsel for the Company.

          (d) The undersigned is familiar with the provisions of Rule 144,
promulgated under the Securities Act, which, in substance, permits limited
public resale of "restricted securities" acquired, directly or indirectly, from
the issuer thereof (or from an affiliate of such issuer), in a non-public
offering subject to the satisfaction of certain conditions, including, among
other things: (1) The availability of certain public information about the
Company; (2) the resale occurring not less than two years after the party has
purchased, and made full payment for, within the meaning of Rule 144, the
securities to be sold; and, in the case of an affiliate, or of a non-affiliate
who has held the securities less than three years; and (3) the sale being made
through a broker in an unsolicited
<PAGE>
 
"broker's transaction" or in transactions directly with a market maker, as said
term is defined under the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), and the amount of securities being sold during any three month
period not exceeding the specified limitation stated therein, if applicable.
There can be no assurances that the requirements of Rule 144 will be met, or
that the Securities will ever be saleable.

          (e) The undersigned further understands that at the time the
undersigned wishes to sell the Securities there may be no public market upon
which to make such a sale, and that, even if such a public market then exists,
the Company may not be satisfying the current public information requirements of
Rule 144, and that, in such event, the undersigned would be precluded from
selling the Securities under Rule 144 even if the two-year minimum holding
period has been satisfied.

          (f) The undersigned further understands that in the event all of the
applicable requirements of Rule 144 are not satisfied registration under the
Securities Act, compliance with some other registration exemption or the
notification to the Company of the proposed disposition by it and the furnishing
to the Company of (i) detailed information regarding the disposition, and (ii)
and opinion of its counsel to the effect that such disposition will not require
registration (the undersigned understands such counsel's opinion must concur
with the opinion by counsel for the Company and the undersigned must have been
informed of such compliance) will be required and that, notwithstanding the fact
that Rule 144 is not exclusive, the Staff of the SEC has expressed its opinion
that person proposing to sell private placement securities other than in a
registered offering and otherwise than pursuant to Rule 144 will have a
substantial burden of proof in establishing that an exemption from registration
is available for such offers or sales, and that such persons and their
respective brokers who participate in such transactions do so at their own risk.

                      SECTION 2  THE STOCK INCENTIVE PLAN

          2.1  Purpose of the Plan.  The Plan is intended to (a) provide
               -------------------                                      
incentive to officers and key employees of the Company and its Affiliates to
stimulate their efforts toward the continued success of the Company and to
operate and manage the business in a manner that will provide for the long-term
growth and profitability of the Company; (b) encourage stock ownership by
officers and key employees by providing them with a means to acquire a
proprietary interest in the Company, acquire shares of Stock, or to receive
compensation which is based upon appreciation in the value of Stock; and (c)
provide a means of obtaining, rewarding and retaining key personnel and
consultants.

          2.2  Stock Subject to the Plan.  Subject to adjustment in accordance
               -------------------------                                      
with Section 5.2, 1,700,000 shares of Stock (the "Maximum Plan Shares") are
hereby reserved exclusively for issuance pursuant to Stock Incentives.  At no
time may the Company have outstanding under the Plan, Stock Incentives subject
to Section 16 of the Exchange Act and shares of Stock issued in respect of Stock
Incentives under the Plan in excess of the Maximum Plan Shares.  The shares of
Stock attributable to the nonvested, unpaid, unexercised, unconverted or
otherwise unsettled portion of any Stock Incentive that is forfeited or
cancelled or expires or terminates for any reason without becoming vested, paid,
exercised, converted or otherwise settled in full will again be available for
purposes of the Plan.

          2.3  Administration of the Plan.  The Plan is administered by the
               --------------------------                                  
Committee.  The Committee has full authority in its discretion to determine the
officers and key employees of the Company or its Affiliates to whom Stock
Incentives will be granted and the terms and provisions of Stock Incentives,
subject to the Plan.  Subject to the provisions of the Plan, the Committee has
full and conclusive authority to interpret the Plan; to prescribe, amend and
rescind rules and regulations relating to the Plan; to determine the terms and
provisions of the respective Stock Incentive Agreements and to make all other
determinations necessary or advisable for the proper administration of the Plan.
The Committee's determinations under the Plan need not be uniform and may be
made by it selectively among persons who receive, or are eligible to receive,
awards under the Plan (whether or not such persons are similarly situated).  The
Committee's decisions are final and binding on all Participants.

          2.4  Eligibility and Limits.  Stock Incentives may be granted only to
               ----------------------                                          
officers, and key employees and consultants of the Company, or any Affiliate of
the Company; provided, however, that an incentive stock option may only be
granted to an employee of the Company or any Subsidiary.  In the case of
incentive stock options, the aggregate Fair Market Value (determined as at the
date an incentive stock option is granted) of stock with respect to which stock
options intended to meet the requirements of Code Section 422 become exercisable
for the first time by an individual during any calendar year under all plans of
the Company and its

                                      -4-
<PAGE>
 
Subsidiaries may not exceed $100,000; provided further, that if the limitation
is exceeded, the incentive stock option(s) which cause the limitation to be
exceeded will be treated as non-qualified stock option(s).

                      SECTION 3  TERMS OF STOCK INCENTIVES

          3.1  Terms and Conditions of All Stock Incentives.
               --------------------------------------------

               (a) The number of shares of Stock as to which a Stock Incentive
may be granted will be determined by the Committee in its sole discretion,
subject to the provisions of Section 2.2 as to the total number of shares
available for grants under the Plan and subject to the limits on Options and
Stock Appreciation Rights in the following sentence. To the extent required
under Section 162(m) of the Code and the regulations thereunder for compensation
to be treated as qualified performance based compensation, the maximum number of
shares of Stock with respect to which Options or Stock Appreciation Rights may
be granted during any one year period to any employee may not exceed 1,700,000.

              (b) Each Stock Incentive will either be evidenced by a Stock
Incentive Agreement in such form and containing such terms, conditions and
restrictions as the Committee may determine to be appropriate, or be made
subject to the terms of a Stock Incentive Program, containing such terms,
conditions and restrictions as the Committee may determine to be appropriate.
Each Stock Incentive Agreement or Stock Incentive Program is subject to the
terms of the Plan and any provisions contained in the Stock Incentive Agreement
or Stock Incentive Program that are inconsistent with the Plan are null and
void.

              (c) The date a Stock Incentive is granted will be the date on
which the Committee has approved the terms and conditions of the Stock Incentive
and has determined the recipient of the Stock Incentive and the number of shares
covered by the Stock Incentive, and has taken all such other actions necessary
to complete the grant of the Stock Incentive.

              (d) Any Stock Incentive may be granted in connection with all or
any portion of a previously or contemporaneously granted Stock Incentive.
Exercise or vesting of a Stock Incentive granted in connection with another
Stock Incentive may result in a pro rata surrender or cancellation of any
related Stock Incentive, as specified in the applicable Stock Incentive
Agreement or Stock Incentive Program.

          3.2  Terms and Conditions of Options.  Each Option granted under the
               -------------------------------                                
Plan must be evidenced by a Stock Incentive Agreement.  At the time any Option
is granted, the Committee will determine whether the Option is to be an
incentive stock option described in Code Section 422 or a non-qualified stock
option, and the Option must be clearly identified as to its status as an
incentive stock option or a non-qualified stock option.  Incentive stock options
may only be granted to employees of the Company or any Subsidiary.  At the time
any incentive stock option granted under the Plan is exercised, the Company will
be entitled to legend the certificates representing the shares of Stock
purchased pursuant to the Option to clearly identify them as representing the
shares purchased upon the exercise of an incentive stock option.  An incentive
stock option may only be granted within ten (10) years from the earlier of the
date the Plan is adopted or approved by the Company's stockholders.

               (a) Option Price. Subject to adjustment in accordance with
                   ------------
Section 5.2 and the other provisions of this Section 3.2, the exercise price
(the "Exercise Price") per share of Stock purchasable under any Option must be
as set forth in the applicable Stock Incentive Agreement, but in no event may it
be less than the Fair Market Value on the date the Option is granted with 
respect to an incentive stock option. With respect to each grant of an incentive
stock option to a Participant who is an Over 10% Owner, the Exercise Price may
not be less than 110% of the Fair Market Value on the date the Option is
granted. The Exercise Price of an Option may not be amended or modified after
the grant of the Option, and an Option may not be surrendered in consideration
of or exchanged for a grant of a new Option having an Exercise Price below that
of the Option which was surrendered or exchanged.

               (b) Option Term. Any incentive stock option granted to a
                   -----------
Participant who is not an Over 10% Owner is not exercisable after the expiration
of ten (10) years after the date the Option is granted. Any incentive stock
option granted to an Over 10% Owner is not exercisable after the expiration of
five (5) years after the date the Option is granted. The term of any Non-
Qualified Stock Option must be as specified in the applicable Stock Incentive
Agreement.

               (c) Payment. Payment for all shares of Stock purchased pursuant
                   -------
to exercise of an Option will be made in any form or manner authorized by the
Committee in the Stock Incentive Agreement or by amendment thereto, including,
but not limited to, cash or, if the Stock Incentive Agreement provides:

               (i) by delivery to the Company of a number of shares of Stock
                   which have been owned by the holder for at least six (6)
                   months prior to the date of exercise having an aggregate Fair
                   Market Value of not less than the product of the Exercise
                   Price multiplied by the number of shares the Participant
                   intends to purchase upon exercise of the Option on the date
                   of delivery;

              (ii) in a cashless exercise through a broker; or

                                      -6-
<PAGE>
 
             (iii) by having a number of shares of Stock withheld, the Fair
                   Market Value of which as of the date of exercise is
                   sufficient to satisfy the Exercise Price.

In its discretion, the Committee also may authorize (at the time an Option is
granted or thereafter) Company financing to assist the Participant as to payment
of the Exercise Price on such terms as may be offered by the Committee in its
discretion.  Payment must be made at the time that the Option or any part
thereof is exercised, and no shares may be issued or delivered upon exercise of
an option until full payment has been made by the Participant.  The holder of an
Option, as such, has none of the rights of a stockholder.

          (d) Conditions to the Exercise of an Option.  Each Option granted
              ---------------------------------------                      
under the Plan is exercisable by whom, at such time or times, or upon the
occurrence of such event or events, and in such amounts, as the Committee
specifies in the Stock Incentive Agreement; provided, however, that subsequent
to the grant of an Option, the Committee, at any time before complete
termination of such Option, may accelerate the time or times at which such
Option may be exercised in whole or in part, including, without limitation, upon
a Change in Control and may permit the Participant or any other designated
person to exercise the Option, or any portion thereof, for all or part of the
remaining Option term, notwithstanding any provision of the Stock Incentive
Agreement to the contrary.

          (e) Termination of Incentive Stock Option.  With respect to an
              -------------------------------------                     
incentive stock option, in the event of termination of employment of a
Participant, the Option or portion thereof held by the Participant which is
unexercised will expire, terminate, and become unexercisable no later than the
expiration of three (3) months after the date of termination of employment;
provided, however, that in the case of a holder whose termination of employment
is due to death or Disability, one (1) year will be substituted for such three
(3) month period; provided, further that such time limits may be exceeded by the
Committee under the terms of the grant, in which case, the incentive stock
option will be a nonqualified option if it is exercised after the time limits
that would otherwise apply.  For purposes of this Subsection (e), termination of
employment of the Participant will not be deemed to have occurred if the
Participant is employed by another corporation (or a parent or subsidiary
corporation of such other corporation) which has assumed the incentive stock
option of the Participant in a transaction to which Code Section 424(a) is
applicable.

          (f) Special Provisions for Certain Substitute Options.
              -------------------------------------------------  
Notwithstanding anything to the contrary in this Section 3.2, any Option issued
in substitution for an option previously issued by another entity, which
substitution occurs in connection with a transaction to which Code Section
424(a) is applicable, may provide for an exercise price computed in accordance
with such Code Section and the regulations thereunder and may contain such other
terms and conditions as the Committee may prescribe to cause such substitute
Option to contain as nearly as possible the same terms and conditions (including
the applicable vesting and termination provisions) as those contained in the
previously issued option being replaced thereby.

     3.3  Terms and Conditions of Stock Appreciation Rights.  Each Stock
          -------------------------------------------------             
Appreciation Right granted under the Plan must be evidenced by a Stock Incentive
Agreement.  A Stock Appreciation Right entitles the Participant to receive the
excess of (1) the Fair Market Value of a specified or determinable number of
shares of the Stock at the time of payment or exercise over (2) a specified or
determinable price which, in the case of a Stock Appreciation Right granted in
connection with an Option, may not be less than the Exercise Price for that
number of shares subject to that Option.  A Stock Appreciation Right granted in
connection with a Stock Incentive may only be exercised to the extent that the
related Stock Incentive has not been exercised, paid or otherwise settled.

          (a) Settlement.  Upon settlement of a Stock Appreciation Right, the
              ----------                                                     
Company must pay to the Participant the appreciation in cash or shares of Stock
(valued at the aggregate Fair Market Value on the date of payment or exercise)
as provided in the Stock Incentive Agreement or, in the absence of such
provision, as the Committee may determine.

          (b) Conditions to Exercise.  Each Stock Appreciation Right granted
              ----------------------                                        
under the Plan is exercisable or payable at such time or times, or upon the
occurrence of such event or events, and in such amounts, as the Committee
specifies in the Stock Incentive Agreement; provided, however, that subsequent
to the grant of a Stock Appreciation Right, the Committee, at any time before
complete termination of such Stock Appreciation Right, may accelerate the time
or times at which such Stock Appreciation Right may be exercised or paid in
whole or in part.

     3.4  Terms and Conditions of Stock Awards.  The number of shares of Stock
          ------------------------------------                                
subject to a Stock Award and restrictions or conditions on such shares, if any,
will be as the Committee determines, and the certificate for such shares will
bear evidence of any restrictions or conditions.  Subsequent to the date of the
grant of the Stock Award, the Committee has the power to permit, in its
discretion, an acceleration of the expiration of an applicable restriction
period with respect to any part or all of the shares awarded to a Participant.
The Committee may require a cash payment from the Participant in an amount no
greater than the aggregate Fair Market Value of the shares of Stock awarded
determined at the date of grant in exchange for the grant of a Stock Award or
may grant a Stock Award without the requirement of a cash payment.

     3.5  Terms and Conditions of Dividend Equivalent Rights.  A Dividend
          --------------------------------------------------             
Equivalent Right entitles the Participant to receive payments from the Company
in an amount determined by reference to any cash dividends paid on a specified
number of shares of Stock to Company stockholders of record during the period
such rights are effective.  The Committee may impose such restrictions and
conditions on any Dividend Equivalent Right as the Committee in its discretion
shall determine, including the date any such right shall terminate and may
reserve the right to terminate, amend or suspend any such right at any time.

                                      -8-
<PAGE>
 
          (a) Payment.  Payment in respect of a Dividend Equivalent Right may be
              -------                                                           
made by the Company in cash or shares of Stock (valued at Fair Market Value on
the date of payment) as provided in the Stock Incentive Agreement or Stock
Incentive Program, or, in the absence of such provision, as the Committee may
determine.

          (b) Conditions to Payment.  Each Dividend Equivalent Right granted
              ---------------------                                         
under the Plan is payable at such time or times, or upon the occurrence of such
event or events, and in such amounts, as the Committee specifies in the
applicable Stock Incentive Agreement or Stock Incentive Program; provided,
however, that subsequent to the grant of a Dividend Equivalent Right, the
Committee, at any time before complete termination of such Dividend Equivalent
Right, may accelerate the time or times at which such Dividend Equivalent Right
may be paid in whole or in part.

     3.6  Terms and Conditions of Performance Unit Awards.  A Performance Unit
          -----------------------------------------------                     
Award shall entitle the Participant to receive, at a specified future date,
payment of an amount equal to all or a portion of the value of a specified or
determinable number of units (stated in terms of a designated or determinable
dollar amount per unit) granted by the Committee.  At the time of the grant, the
Committee must determine the base value of each unit, the number of units
subject to a Performance Unit Award, the performance factors applicable to the
determination of the ultimate payment value of the Performance Unit Award and
the period over which Company performance shall be measured.  The Committee may
provide for an alternate base value for each unit under certain specified

              ---------------------                                            
the Plan shall be payable at such time or times, or upon the occurrence of such

                        SECTION 4  RESTRICTIONS ON STOCK

     4.1  Escrow of Shares.  Any certificates representing the shares of Stock
          ----------------                                                    
issued under the Plan will be issued in the Participant's name, but, if the
applicable Stock Incentive Agreement or Stock Incentive Program so provides, the
shares of Stock will be held by a custodian designated by the Committee (the
"Custodian").  Each applicable Stock Incentive Agreement or Stock Incentive
Program providing for transfer of shares of Stock to the Custodian must appoint
the Custodian as the attorney-in-fact for the Participant for the term specified
in the applicable Stock Incentive Agreement or Stock Incentive Program, with
full power and authority in the Participant's name, place and stead to transfer,
assign and convey to the Company any shares of Stock held by the Custodian for
such Participant, if the Participant forfeits the shares under the terms of the
applicable Stock Incentive Agreement or Stock Incentive Program.  During the
period that the Custodian holds the shares subject to this Section, the
Participant is entitled to all rights, except as provided in the applicable
Stock Incentive Agreement or Stock Incentive Program, applicable to shares of
Stock not so held.  Any dividends declared on shares of Stock held by the
Custodian must provide in the applicable Stock Incentive Agreement or Stock
Incentive Program, be paid directly to the Participant or, in the alternative,
be retained by the Custodian or by the Company until the expiration of the term
specified in the applicable Stock Incentive Agreement or Stock Incentive Program
and shall then

                                      -10-
<PAGE>
 
be delivered, together with any proceeds, with the shares of Stock to the
Participant or to the Company, as applicable.

     4.2  Restrictions on Transfer.  The Participant does not have the right to
          ------------------------                                             
make or permit to exist any disposition of the shares of Stock issued pursuant
to the Plan except as provided in the Plan or the applicable Stock Incentive
Agreement or Stock Incentive Program.  Any disposition of the shares of Stock
issued under the Plan by the Participant not made in accordance with the Plan or
the applicable Stock Incentive Agreement or Stock Incentive Program will be
void.  The Company will not recognize, or have the duty to recognize, any
disposition not made in accordance with the Plan and the applicable Stock
Incentive Agreement or Stock Incentive Program, and the shares so transferred
will continue to be bound by the Plan and the applicable Stock Incentive
Agreement or Stock Incentive Program.


                         SECTION 5  GENERAL PROVISIONS

     5.1  Withholding.  The Company must deduct from all cash distributions
          -----------                                                      
under the Plan any taxes required to be withheld by federal, state or local
government.  Whenever the Company proposes or is required to issue or transfer
shares of Stock under the Plan or upon the vesting of any Stock Award, the
Company has the right to require the recipient to remit to the Company an amount
sufficient to satisfy any federal, state and local withholding tax requirements
prior to the delivery of any certificate or certificates for such shares or the
vesting of such Stock Award.  A Participant may pay the withholding tax in cash,
or, if the applicable Stock Incentive Agreement or Stock Incentive Program
provides, a Participant may elect to have the number of shares of Stock he is to
receive reduced by, or with respect to a Stock Award, tender back to the
Company, the smallest number of whole shares of Stock which, when multiplied by
the Fair Market Value of the shares of Stock determined as of the Tax Date
(defined below), is sufficient to satisfy federal, state and local, if any,
withholding taxes arising from exercise or payment of a Stock Incentive (a
"Withholding Election").  A Participant may make a Withholding Election only if
both of the following conditions are met:

          (a) The Withholding Election must be made on or prior to the date on
which the amount of tax required to be withheld is determined (the "Tax Date")
by executing and delivering to the Company a properly completed notice of
Withholding Election as prescribed by the Committee; and

          (b) Any Withholding Election made will be irrevocable except on six
months advance written notice delivered to the Company; however, the Committee
may in its sole discretion disapprove and give no effect to the Withholding
Election.

     5.2  Changes in Capitalization; Merger; Liquidation.
          ---------------------------------------------- 

          (a) The number of shares of Stock reserved for the grant of Options,
Dividend Equivalent Rights, Performance Unit Awards, Phantom Shares, Stock
Appreciation Rights and Stock Awards; the number of shares of Stock reserved for
issuance upon the exercise or payment, as applicable, of each outstanding
Option, Dividend Equivalent Right, Phantom Share and Stock Appreciation Right
and upon vesting or grant, as applicable, of each Stock Award; the Exercise
Price of each outstanding Option and the specified number of shares of Stock to
which each outstanding Dividend Equivalent Right, Phantom Share and Stock
Appreciation Right pertains must be proportionately adjusted for any increase or
decrease in the number of issued shares of Stock resulting from a subdivision or
combination of shares or the payment of a stock dividend in shares of Stock to
holders of outstanding shares of Stock or any other increase or decrease in the
number of shares of Stock outstanding effected without receipt of consideration
by the Company.

          (b) In the event of a merger, consolidation or other reorganization of
the Company or tender offer for shares of Stock, the Committee may make such
adjustments with respect to awards and take such other action as it deems
necessary or appropriate to reflect such merger, consolidation, reorganization
or tender offer, including, without limitation, the substitution of new awards,
or the adjustment of outstanding awards, the acceleration of awards, the removal
of restrictions on outstanding awards, or the termination of outstanding awards
in exchange for the cash value determined in good faith by the Committee of the
vested portion of the award.  Any adjustment pursuant to this Section 5.2 may
provide, in the Committee's discretion, for the elimination without payment
therefor of any fractional shares that might otherwise become subject to any
Stock Incentive, but except as set forth in this Section may not otherwise
diminish the then value of the Stock Incentive.

          (c) The existence of the Plan and the Stock Incentives granted
pursuant to the Plan must not affect in any way the right or power of the
Company to make or authorize any adjustment, reclassification, reorganization or
other change in its capital or business structure, any merger or consolidation
of the Company, any issue of debt or equity securities having preferences or
priorities as to the Stock or the rights thereof, the dissolution or liquidation
of the Company, any sale or transfer of all or any part of its business or
assets, or any other corporate act or proceeding.

     5.3  Cash Awards.  The Committee may, at any time and in its discretion,
          -----------                                                        
grant to any holder of a Stock Incentive the right to receive, at such times and
in such amounts as determined by the Committee in its discretion, a cash amount
which is intended to reimburse such person for all or a portion of the federal,
state and local income taxes imposed upon such person as a consequence of the
receipt of the Stock Incentive or the exercise of rights thereunder.

                                      -12-
<PAGE>
 
     5.4  Compliance with Code.  All incentive stock options to be granted
          --------------------                                            
hereunder are intended to comply with Code Section 422, and all provisions of
the Plan and all incentive stock options granted hereunder must be construed in
such manner as to effectuate that intent.

     5.5  Right to Terminate Employment.  Nothing in the Plan or in any Stock
          -----------------------------                                      
Incentive confers upon any Participant the right to continue as an employee or
officer of the Company or any of its Affiliates or affect the right of the
Company or any of its Affiliates to terminate the Participant's employment at
any time.

     5.6  Non-alienation of Benefits.  Other than as specifically provided with
          --------------------------                                           
regard to the death of a Participant, no benefit under the Plan may be subject
in any manner to anticipation, alienation, sale, transfer, assignment, pledge,
encumbrance or charge; and any attempt to do so shall be void.  No such benefit
may, prior to receipt by the Participant, be in any manner liable for or subject
to the debts, contracts, liabilities, engagements or torts of the Participant.

     5.7  Restrictions on Delivery and Sale of Shares; Legends.  Each Stock
          ----------------------------------------------------             
Incentive is subject to the condition that if at any time the Committee, in its
discretion, shall determine that the listing, registration or qualification of
the shares covered by such Stock Incentive upon any securities exchange or under
any state or federal law is necessary or desirable as a condition of or in
connection with the granting of such Stock Incentive or the purchase or delivery
of shares thereunder, the delivery of any or all shares pursuant to such Stock
Incentive may be withheld unless and until such listing, registration or
qualification shall have been effected.  If a registration statement is not in
effect under the Securities Act of 1933 or any applicable state securities laws
with respect to the shares of Stock purchasable or otherwise deliverable under
Stock Incentives then outstanding, the Committee may require, as a condition of
exercise of any Option or as a condition to any other delivery of Stock pursuant
to a Stock Incentive, that the Participant or other recipient of a Stock
Incentive represent, in writing, that the shares received pursuant to the Stock
Incentive are being acquired for investment and not with a view to distribution
and agree that the shares will not be disposed of except pursuant to an
effective registration statement, unless the Company shall have received an
opinion of counsel that such disposition is exempt from such requirement under
the Securities Act of 1933 and any applicable state securities laws.  The
Company may include on certificates representing shares delivered pursuant to a
Stock Incentive such legends referring to the foregoing representations or
restrictions or any other applicable restrictions on resale as the Company, in
its discretion, shall deem appropriate.

     5.8  Listing and Legal Compliance.  The Committee may suspend the exercise
          ----------------------------                                         
or payment of any Stock Incentive so long as it determines that securities
exchange listing or registration or qualification under any securities laws is
required in connection therewith and has not been completed on terms acceptable
to the Committee.

     5.9  Termination and Amendment of the Plan.  The Board of Directors at any
          -------------------------------------                                
time may amend or terminate the Plan without stockholder approval; provided,
however, that the

                                      -13-
<PAGE>
 
Board of Directors may condition any amendment on the approval of stockholders
of the Company if such approval is necessary or advisable with respect to tax,
securities or other applicable laws.  No such termination or amendment without
the consent of the holder of a Stock Incentive may adversely affect the rights
of the Participant under such Stock Incentive.

     5.10 Stockholder Approval.  The Plan must be submitted to the stockholders
          --------------------                                                 
of the Company for their approval within twelve (12) months before or after the
adoption of the Plan by the Board of Directors of the Company.  If such approval
is not obtained, any Stock Incentive granted hereunder will be void.

     5.11 Choice of Law.  The laws of the State of Maryland govern the Plan, to
          -------------                                                        
the extent not preempted by federal law, without reference to the principles of
conflict of laws.

     5.12 Effective Date of Plan.  The Plan shall become effective April 17,
          ----------------------                                            
1997, subject, however, to the approval of the Plan by the Company's
shareholders.  Stock Incentives granted hereunder prior to such approval shall
be conditioned upon such approval.  Unless such approval is obtained within one
year after the effective date of this Plan and any Stock Incentives awarded
hereunder shall become void thereafter.

cash, (ii) by electing, irrevocably and in writing in substantially the form
attached hereto as Exhibit 2 (a "Withholding Election"), to have the actual

number of shares of Common Stock issuable upon exercise reduced by the smallest
number of whole shares of Common Stock which, when multiplied by the fair market
value of the Common Stock as of the date the Option is exercised, is sufficient
to satisfy the amount of withholding tax; or (iii) by any combination of the
above.  Optionee may make a Withholding Election only if the following
conditions are met:

          (a) the Withholding Election is made by executing and delivering to

     substantially the form of Exhibit 2 attached hereto;

          (b) the Withholding Election is delivered to the Company sufficiently
     in advance of the date on which the amount of tax required to be withheld
     is determined (the "Tax Date") as the Committee under the Plan (the
     "Committee") determines is necessary or appropriate to satisfy the
     conditions of the exemptions provided under Rule 16b-3 promulgated under
     the Securities Exchange Act of 1934 (the "1934 Act");

          (c) any Withholding Election is irrevocably given in a manner that
     satisfies the requirements of the exemption provided under Rule 16b-3
     promulgated under the 1934 Act; and

          (d) if the Optionee is considered by the Committee not to be subject

     than the Tax Date.

     Notwithstanding anything to the contrary herein, the Committee may in its
sole discretion disapprove and give no effect to any Withholding Election.

     4.   Term and Termination of Option.  The Option shall terminate on the

Optionee hereunder shall terminate, and thereafter be null and void.

          incapacity during illness) to substantially perform duties with the
          Company or a Subsidiary,

                                                                     Page 3 of 6

     5.   Rights as Shareholder.  Until the stock certificates reflecting the
          ---------------------                                              
Option Shares accruing to the Optionee upon exercise of the Option are issued to
the Optionee, the Optionee shall have no rights as a shareholder with respect to
such Option Shares.  The Company shall make no adjustment for any dividends or
distributions or other rights on or with respect to Option Shares for which the
record date is prior to the issuance of that stock certificate, except as the
Plan or this Award otherwise provides.

(or in the event of his disability, by his legal representative) and after his
death, only by legal representative of the Optionee's estate.

     7.   Changes in Capitalization; Merger; Reorganization.
          ------------------------------------------------- 

          (a) The number of Option Shares and the Exercise Price shall be

     issued shares of Common Stock resulting from a subdivision or combination
     of shares or the payment of a stock dividend in shares of Common Stock to
     holders of outstanding shares of Common Stock or any other increase or
     decrease in the number of shares of Common Stock outstanding effected
     without receipt of consideration by the Company.

          (b) In the event of a merger, consolidation or other reorganization
     involving the Company or a tender offer for shares of Common Stock, the
     Committee may, in its sole discretion, adjust the number and class of
     securities subject to the Option, with a corresponding adjustment made in
     the Exercise Price; substitute a new option to replace the Option; or
     accelerate the termination of the Option Period to a date prior to the
     occurrence of any event specified in Section 4 above; or, terminate the
     Option in consideration of payment to Optionee of the excess of the then
     Fair Market Value (as defined in the Plan) of the vested Option Shares over
     the Exercise Price of the vested Option Shares.

          (c) The existence of the Plan and this Award shall not affect in any
     way the right or power of the Company to make or authorize any adjustment,
     reclassification, reorganization or other change in its capital or business
     structure, any merger or consolidation of the Company, any issue of debt or
     equity securities having preferences or priorities as to the Common Stock
     or the rights thereof, the dissolution or liquidation of

                                                                     Page 4 of 6

     the Company, any sale or transfer of all or any part of its business or
     assets, or any other corporate act or proceeding.

          -------------------------------                                
subject to the condition that if at any time the Committee, in its discretion,
shall determine that the listing, registration or qualification of the shares
covered by the Option upon any securities exchange or under any state or federal
law is necessary or desirable as a condition of or in connection with the
delivery of shares thereunder, the delivery of any or all shares pursuant to the
Option may be withheld unless and until such listing, registration or
qualification shall have been effected.  The Optionee shall deliver to the
Company, prior to the exercise of the Option, such information, representations
and warranties as the Company may reasonably request in order for the Company to
be able to satisfy itself that the Option Shares being acquired in accordance
with the terms of an applicable exemption from the securities registration

                                                                     Page 5 of 6

Attn:  Chief Financial Officer

Re:  Exercise of Non-Qualified Stock Option

Gentlemen:

     Subject to acceptance hereof in writing by ZMAX Corporation (the "Company")
pursuant to the provisions of the ZMAX Corporation 1997 Stock Incentive Plan, I
hereby give at least ten days but not more than thirty days prior notice of my
election to exercise options granted to me to purchase ______________ shares of
Common Stock of the Company under the Non-Qualified Stock Option Award (the
"Award") pursuant to the ZMAX Corporation 1997 Stock Incentive Plan dated as of
____________.  The purchase shall take place as of __________, 199__ (the
"Exercise Date").

     On or before the Exercise Date, I will pay the applicable purchase price as
follows:

     [_]  by delivery of cash or a certified check for $___________ for the full
          purchase price payable to the order of ZMAX Corporation.

     [_]  by delivery of a certified check for $___________ representing a
          portion of the purchase price with the balance to consist of shares of
          Common Stock that I have owned for at least six months and that are
          represented by a stock certificate I will surrender to the Company
          with my endorsement.  If the number of shares of Common Stock
          represented by such stock certificate exceed the number to be applied
          against the purchase price, I understand that a new stock certificate
          will be issued to me reflecting the excess number of shares.


            EXHIBIT 1 to Non-Qualified Stock Option Award - Page 1
<PAGE>
 
     [_]  by delivery of a stock certificate representing shares of Common Stock
          that I have owned for at least six months which I will surrender to
          the Company with my endorsement as payment of the purchase price.  If
          the number of shares of Common Stock represented by such certificate
          exceed the number to be applied against the purchase price, I
          understand that a new certificate will be issued to me reflecting the
          excess number of shares.

     [_]  by delivery of the purchase price by ________________, a broker,
          dealer or other "creditor" as defined by Regulation T issued by the
          Board of Governors of the Federal Reserve System.  I hereby authorize
          the Company to issue a stock certificate in number of shares indicated
          above in the name of said broker, dealer or other creditor or its
          nominee pursuant to instructions received by the Company and to
          deliver said stock certificate directly to that broker, dealer or
          other creditor (or to such other party specified in the instructions
          received by the Company from the broker, dealer or other creditor)
          upon receipt of the purchase price.

     The required federal, state and local income tax withholding obligations on
the exercise of the Award shall also be paid in cash or by certified check on or
before the Exercise Date, or will be satisfied in the manner provided in the
Withholding Election previously tendered or (if I am no longer a Section 16(b)
reporting person) to be tendered to the Company no later than the indicated date
of purchase.

     As soon as the stock certificate is registered in my name, please deliver
it to me at the above address.

     If the Common Stock being acquired is not registered for issuance to and
resale by the Optionee pursuant to an effective registration statement on Form
S-8 (or successor form) filed under the Securities Act of 1933, as amended (the
"1933 Act"), I hereby represent, warrant, covenant, and agree with the Company
as follows:

          The shares of the Common Stock being acquired by me will be acquired
     for my own account without the participation of any other person, with the
     intent of holding the Common Stock for investment and without the intent of
     participating, directly or indirectly, in a distribution of the Common
     Stock and not with a view to, or for resale in connection with, any
     distribution of the Common Stock, nor am I aware of the existence of any
     distribution of the Common Stock;

          I am not acquiring the Common Stock based upon any representation,
     oral or written, by any person with respect to the future value of, or
     income from, the Common Stock but rather upon an independent examination
     and judgment as to the prospects of the Company;

          The Common Stock was not offered to me by means of publicly
     disseminated advertisements or sales literature, nor am I aware of any
     offers made to other persons by such means;


            EXHIBIT 1 to Non-Qualified Stock Option Award - Page 2
<PAGE>
 
          I am able to bear the economic risks of the investment in the Common
     Stock, including the risk of a complete loss of my investment therein;

          I understand and agree that the Common Stock will be issued and sold
     to me without registration under any state law relating to the registration
     of securities for sale, and will be issued and sold in reliance on the
     exemptions from registration under the 1933 Act, provided by Sections 3(b)
     and/or 4(2) thereof and the rules and regulations promulgated thereunder;

          The Common Stock cannot be offered for sale, sold or transferred by me
     other than pursuant to: (A) an effective registration under the 1933 Act or
     in a transaction otherwise in compliance with the 1933 Act; and (B)
     evidence satisfactory to the Company of compliance with the applicable
     securities laws of other jurisdictions.  The Company shall be entitled to
     rely upon an opinion of counsel satisfactory to it with respect to
     compliance with the above laws;

          The Company will be under no obligation to register the Common Stock
     or to comply with any exemption available for sale of the Common Stock
     without registration or filing, and the information or conditions necessary
     to permit routine sales of securities of the Company under Rule 144 under
     the 1933 Act are not now available and no assurance has been given that it
     or they will become available.  The Company is under no obligation to act
     in any manner so as to make Rule 144 available with respect to the Common
     Stock;

          I have and have had complete access to and the opportunity to review
     and make copies of all material documents related to the business of the
     Company, including, but not limited to, contracts, financial statements,
     tax returns, leases, deeds and other books and records.  I have examined
     such of these documents as I wished and am familiar with the business and
     affairs of the Company.  I realize that the purchase of the Common Stock is
     a speculative investment and that any possible profit therefrom is
     uncertain;

          I have had the opportunity to ask questions of and receive answers
     from the Company and any person acting on its behalf and to obtain all
     material information reasonably available with respect to the Company and
     its affairs.  I have received all information and data with respect to the
     Company which I have requested and which I have deemed relevant in
     connection with the evaluation of the merits and risks of my investment in
     the Company;

          I have such knowledge and experience in financial and business matters
     that I am capable of evaluating the merits and risks of the purchase of the
     Common Stock hereunder and I am able to bear the economic risk of such
     purchase; and

          The agreements, representations, warranties and covenants made by me
     herein extend to and apply to all of the Common Stock of the Company issued
     to me pursuant to this Award.  Acceptance by me of the certificate
     representing such Common Stock shall


            EXHIBIT 1 to Non-Qualified Stock Option Award - Page 3
<PAGE>
 
     constitute a confirmation by me that all such agreements, representations,
     warranties and covenants made herein shall be true and correct at that
     time.

     I understand that the certificates representing the shares being purchased
by me in accordance with this notice shall bear a legend referring to the
foregoing covenants, representations and warranties and restrictions on
transfer, and I agree that a legend to that effect may be placed on any
certificate which may be issued to me as a substitute for the certificates being
acquired by me in accordance with this notice.

                                       Very truly yours,

     This election relates to the Option identified in Paragraph 3 below.  I
hereby certify that:

          [_]  the legal guardian of the original recipient of the Option.

     (3)  The Option pursuant to which this election relates was issued under

          name of ____________________________ for the purchase of a total of
          ____________ shares of Common Stock.  This election relates to
          ____________ shares of Common Stock issuable upon exercise of the
          Option (the "Common Stock"), provided that the numbers set forth above
          shall be deemed changed as appropriate to reflect the applicable Plan
          provisions.

     (4)  In connection with any exercise of the Option with respect to the
          Common Stock, I hereby elect to have certain of the shares issuable
          pursuant to the exercise withheld by the Company for the purpose of
          having the value of the shares applied to pay federal, state and
          local, if any, taxes arising from the exercise.

          The shares to be withheld shall have, as of the Tax Date applicable to
          the exercise, a fair market value equal to the minimum statutory tax
          withholding requirement under federal, state and local law in
          connection with the exercise.

     (5)  This Withholding Election is made no later than the Tax Date and is
          otherwise timely made pursuant to the Plan.

     (6)  I understand that this Withholding Election may not be revised,
          amended or revoked by me (except in a manner that satisfies the
          requirements of the exemption provided under Rule 16b-3 promulgated
          under the Securities Exchange Act of 1934).

     (7)  I further understand that the Company shall withhold from the Common
          Stock a whole number of shares of Common Stock having the value
          specified in Paragraph 4 above.

     (8)  The plan has been made available to me by the Company, I have read and
          understand the Plan and I have no reason to believe that any of the
          conditions therein to the making of this Withholding Election have not
          been met.  Capitalized terms used in this Notice of Withholding
          Election without definition shall have the meanings given to them in
          the Plan.

          of granting awards other than incentive stock options, Fair Market
          Value of the Shares may be determined by the Committee by reference to
          the average market value determined over a period certain or as of
          specified dates, to a tender offer price for the Shares (if settlement
          of an award is triggered by such an event) or to any other reasonable
          measure of fair market value.

     5.4  Each Option granted pursuant to this Plan shall be authorized by the
Committee, shall be evidenced by an Agreement and shall be subject to such
additional terms as set forth in the Agreement.


                            SECTION 6  TERM OF PLAN

     The Plan shall be effective on the date hereof and shall continue to be

submit the Plan to its stockholders for approval within twelve (12) months of
the adoption of the Plan by the Board of Directors.


                    SECTION 7  INDEMNIFICATION OF COMMITTEE

     In addition to such other rights of indemnification that the members of the
Committee may have, each member of the Committee shall be indemnified by the
Company against the reasonable expenses, including attorneys' fees, actually and
necessarily incurred in connection with the defense of any action, suit or
proceeding, or in connection with any appeal therein, to which it may be a party
by reason of any action taken or failure to act under or in connection with the
Plan or any Option granted thereunder, and against all amounts paid by it in
settlement thereof (provided the settlement has received the prior approval of
the Company) or paid by it in satisfaction of a judgment in any such action,
suit or proceeding, except in relation to matters as to which it shall be
adjudged in the action, suit or proceeding that the Committee member is liable
for negligence or misconduct in the performance of its duties; provided that
promptly after institution of the action, suit or proceeding the Committee
member shall in writing offer the Company the opportunity, at its own expense,
to handle and defend such matter.  Upon the delivery to the Committee member of
written notice of assumption by the Company of the defense of such matter, the
Company will not be responsible to the Committee member for any further fees and
disbursements relating to the defense of such matter, including fees and
disbursements of counsel.


                SECTION 8  AMENDMENT AND TERMINATION OF THE PLAN

     The Board of Directors at any time may amend or terminate the Plan without
shareholder approval; provided, however, that the Board of Directors may
condition any amendment on the approval of the shareholders of the Company if
such approval is necessary or advisable with respect to tax, securities or other
applicable laws to which the Company, this Plan, optionees or eligible employees
or directors are subject.  No amendment or termination of the Plan shall
adversely affect the rights of an optionee with regard to his Options without
his consent.

                  SECTION 9  NO OBLIGATION TO EXERCISE OPTION

     The granting of an Option shall impose no obligation upon the Optionee to
exercise the Option.

     10.1 The number of Shares reserved for the grant of Options, the number of
Shares reserved for issuance upon the exercise or payment, as applicable, of
each outstanding Option, and the exercise price of each outstanding Option must
be proportionately adjusted for any increase or decrease in the number of issued
Shares resulting from a subdivision or combination of Shares or the payment of a
stock dividend in Shares to holders of outstanding Shares or any other increase
or decrease in the number of Shares outstanding effected without receipt of
consideration by the Company.

     10.2 In the event of a merger, consolidation or other reorganization of the
Company or tender offer for Shares, the Committee may make such adjustments with
respect to awards and take such other action as it deems necessary or
appropriate to reflect such merger, consolidation, reorganization or tender
offer, including, without limitation, the substitution of new awards, or the
adjustment of outstanding awards, the acceleration of awards, the removal of
restrictions on outstanding awards, or the termination of outstanding awards in
exchange for the cash value determined in good faith by the Committee of the
vested portion of the award.  Any fractional Shares resulting from such
adjustments shall be eliminated.  All adjustments made by the Committee under
this Section shall be conclusive.

     10.3   The existence of the Plan and the Options granted pursuant to the
Plan must not affect in any way the right or power of the Company to make or
authorize any adjustment, reclassification, reorganization or other change in
its capital or business structure, any merger or consolidation of the Company,
any issue of debt or equity securities having preferences or priorities as to
the Stock or the rights thereof, the dissolution or liquidation of the Company,
any sale or transfer of all or any part of its business or assets, or any other
corporate act or proceeding.


                         SECTION 11  WITHHOLDING TAXES

     Whenever the Company proposes or is required to issue Shares to an optionee
who is or was an employee of the Company or a Subsidiary, or to his legatee or
legal representative under this Plan, pursuant to the exercise of an Option
granted under this Plan, the Company shall have the right to require the
recipient to remit to the Company an amount sufficient to satisfy any federal,
state and local withholding tax requirement, if any, prior to the delivery of
any certificate or certificates for such Shares.  An optionee must pay the
withholding tax in cash or by certified check or by the Company deducting a
sufficient number of Shares from the Option Shares issued to satisfy withholding
taxes, in accordance with the Agreement.

                      SECTION 12  RIGHTS AS A STOCKHOLDER

          An Optionee or a transferee of an Optionee shall have no rights as a
stockholder with respect to any Option or Option Shares until the date of the
issuance of a stock certificate to him for the Option Shares.  No adjustment
shall be made for dividends (ordinary or extraordinary, whether in cash,
securities or other property) or distributions or other rights for which the
record date is prior to the date the stock certificate is issued, except as
otherwise provided in the Plan.


                           SECTION 13 GOVERNING LAW

Stock issuable upon exercise reduced by the smallest number of whole shares of
Common Stock which, when multiplied by the fair market value of the Common Stock
as of the date the Option is exercised, is sufficient to satisfy the amount of
withholding tax; or (iii) by any combination of the above.  Optionee may make a
Withholding Election only if the following conditions are met:

     than the Tax Date.

     Notwithstanding anything to the contrary herein, the Committee may in its
sole discretion disapprove and give no effect to any Withholding Election.

     4.   Term and Termination of Option.  The Option shall terminate on the

Re:  Exercise of Non-Qualified Stock Option

Gentlemen:

     Subject to acceptance hereof in writing by ZMAX Corporation (the "Company")
pursuant to the provisions of the ZMAX Corporation 1997 Directors Formula Stock
Option Plan (the "Plan"), I hereby give at least ten days but not more than
thirty days prior notice of my election to exercise options granted to me to
purchase ______________ shares of common stock of the Company under the 1997
Nonqualified Formula Stock Option Award granted on _______________, 199__ (the
"Award").  The purchase shall take place as of __________, ____ (the "Exercise
Date").

     On or before the Exercise Date, I will pay the applicable purchase price as
follows:

     [_]  by delivery of a certified check for $____________ for the full
          purchase price payable to the order of ZMAX Corporation.

     [_]  by delivery of a certified check for $________ representing a portion
          of the purchase price to the order of ________________ with the
          balance to consist of shares of common stock that I have owned for at
          least six months and that are represented by a stock certificate I
          will surrender to the Company with my endorsement.  If the number of

     Covenants and Representations of Optionee.  Optionee represents, warrants,
     -----------------------------------------                                 
covenants, and agrees with the Company as follows as of the date of exercising
the Option:

          The Option is being received for Optionee's own account without the
participation of any other person, with the intent of holding the Option and the
Option Shares issuable pursuant thereto for investment and without the intent of
participating, directly or indirectly, in a distribution of the Option Shares
and not with a view to, or for resale in connection with, any distribution of
the Option Shares or any portion thereof;

          Optionee is not acquiring the Option based upon any representation,
oral or written, by any person with respect to the future value of, or income
from, the Option Shares subject to this Option, but rather upon an independent
examination and judgment as to the prospects of the Company;

          Optionee has received a copy of the Plan, is familiar with the
business and affairs of the Company, and realizes that the receipt of the Option
Shares is a speculative investment and that any possible profit therefrom is
uncertain;

          Optionee has had the opportunity to ask questions of and receive
answers from the Company and any person acting on its behalf and to obtain all
information available with respect to the Plan, the Company and its affairs, and
has received all information and data with respect to the Plan and the Company
that he has requested and which he has deemed relevant in connection with his
receipt of the Option and the Option Shares subject thereto;

          Optionee is able to bear the economic risk of the investment,
including the risk of a complete loss of his investment, and Optionee
acknowledges that he must continue to bear the economic risk of the investment
in the Option Shares received upon Option exercise for an indefinite period;

          Optionee understands and agrees that the Option Shares subject to the
Option may be issued and sold to Optionee without registration under any state
or federal law relating to the registration of securities for sale, and in that
event will be issued and sold in reliance on exemptions from registration under
appropriate state and federal laws;

          The Option Shares issued to Optionee upon exercise of the Option will
not, subject to any other applicable restrictions set forth in the Plan or the
Award, be offered for sale, sold or transferred by Optionee other than pursuant
to:

          (1) an effective registration under applicable state securities laws
or in a transaction which is otherwise in compliance with those laws;

               EXHIBIT A to Directors Formula Stock Option Award

                                                                     Page 2 of 3
<PAGE>
 
          (2) an effective registration under the Securities Act of 1933 (the
"1933 Act"), or a transaction otherwise in compliance with the 1933 Act; and

          (3) evidence satisfactory to the Company of compliance with the
applicable securities laws.

The Company shall be entitled to rely upon an opinion of counsel satisfactory to
it with respect to compliance with the foregoing laws.

          The Company will be under no obligation to register the Option Shares
issuable pursuant to the Option or to comply with any exemption available for
sale of the Option Shares by the Optionee without registration, and the Company
is under no obligation to act in any manner so as to make Rule 144 promulgated
under the 1933 Act available with respect to sale of the Option Shares by the
Optionee;

          A legend indicating that the Option Shares issued pursuant to the
Option has not been registered under the applicable securities laws and
referring to any applicable restrictions on transferability and sale of the
Option Shares may be placed on the certificate or certificates delivered to
Optionee and any transfer agent of the Company may be instructed to require
compliance therewith;

     As soon as the stock certificate is registered in my name, please deliver
it to me at the above address.

                                   Very truly yours,

                             EMPLOYMENT AGREEMENT

     THIS EMPLOYMENT AGREEMENT (this "Agreement") is made on November 6, 1996,
between CENTURY SERVICES, INC., a Maryland corporation (the "Company"), and

     The Executive desires to enter into employment with the Company and the
Company desires to employ the Executive.

     The Executive is a stockholder in ZMAX Corporation, a Nevada corporation
("ZMAX"), the parent company of the Company.

     In consideration of the employment of the Executive by the Company and the
mutual agreements stated below, the parties agree as follows:

                              STATEMENT OF TERMS:

                                   SECTION 1
                              DUTIES OF EXECUTIVE

     1.1  Engagement.  The Company employs the Executive, and the Executive
          ----------                                                       
accepts such employment with the Company, subject to the terms and conditions of
this Agreement.

     1.2  Duties and Responsibilities of Executive.  The Executive will be
          ----------------------------------------                        
employed as the President of the Company and will do and perform all services
and acts necessary or advisable to fulfill the duties of President of the
Company and will conduct and perform such services and activities as may be
determined from time to time by the chief executive officer of the Company.

                                   SECTION 2
                                 COMPENSATION

     2.1  Cash Compensation.  For all services to be rendered by the
          -----------------                                         
Executive under this Agreement, Company will pay the Executive the following
amounts, which payment will be subject to subject withholdings for local, state
and federal taxes, social security, and other deductions required by law or the
policies of the Company, from time to time in effect:

          (a) Interim Base Salary.  The Company will pay the Executive an annual
              -------------------                                               
     gross salary (the "Base Salary") equal to the sum of (i) $8,000 per month
     plus (ii) 20% of the Cash Flow (as defined below) generated by the
     Company's operations up to a maximum of $10,000 in any one month.  The Base
     Salary will be payable on the Company's standard salary payment schedule
     for executive level employees.  For purposes of this provision the term
     "Cash Flow" means, with respect to each calendar month, all operating
     revenues from sales and services and licensing and franchising income (but
     excluding proceeds from loans or capital infusions and proceeds from sales,
     exchanges and other dispositions of property or rights not in the ordinary
     course of business) LESS direct operating expenses including software
     licensing fees and a provision for the Company's income taxes calculated
     based on the then-applicable statutory rates (but excluding capital
     expenses, depreciation, amortization, debt service, dividends and
     intercompany charges other than charges that would be direct operating
     expenses if paid by the Company).  Cash Flow will be determined by Arthur
     Andersen (or such other independent accounting firm then serving the
     Company) for the relevant period on a cash basis.

          (b) Adjusted Base Salary and Bonus.  As soon as practicable after the
              ------------------------------                                   
     date of this Agreement and in no event later than 60 days after the date of
     this Agreement, the Board of Directors of ZMAX will set the Base Salary and
     bonuses of the Executive, which will include a Base Salary and performance
     bonuses and will be evidenced by an addendum to this Agreement executed by
     the Executive and the Company from time to time; provided, however, that
     the annual Base Salary will not be less than $100,000.

In no event will the Executive be entitled to any form of incentive or stock or
performance bonus compensation other than that described in this Agreement or
any addendum to this Agreement.

     2.2  Business Expenses.  The Executive will be entitled to be reimbursed
          -----------------                                                  
for all reasonable and necessary expenses incurred by him in connection with the
performance of his duties of employment under this Agreement in accordance with
the policies of the Company.  The Executive will, as a condition of any such
reimbursement, submit verification of the nature and amount of such expenses in
accordance with the reimbursement policies from time to time adopted by the
Company.

     2.3  Fringe Benefits.  The Executive will have the same rights as all other
          ---------------                                                       
employees to participate in all pension and other retirement plans, medical
insurance, life insurance and other fringe benefit programs, as are now or may
hereafter be established by the Company;

                                      

                                      -2-
<PAGE>
 
provided, however, that such fringe benefits will not be less that those
provided by the Company on the date of this Agreement.  The Executive will
receive 4 weeks paid vacation per year in accordance with the Company's policy
in effect from time to time.

                                   SECTION 3

          ---------------------                                          
employment under this Agreement, the Company will have no further obligation to
the Executive or his personal representative with respect to this Agreement or
his employment by the Company,

                                      -3-
<PAGE>
 
except for the payment of any compensation accrued up to the date of termination
of this Agreement and unpaid at the date of such termination and the payment of
any severance payments that may be due under Section 3.4 of this Agreement and
as set forth in Section 6.3 regarding its agreement to arbitrate certain
disputes under this Agreement.

     3.4  Severance Payment.  In addition to the amounts payable pursuant to
          -----------------                                                 
Section 3.3, if this Agreement is terminated by the death or permanent
disability of Executive pursuant to Section 3.2(a) or by the Company without
cause pursuant to Section 3.2(e), the Company will pay to Executive or
Executive's estate all severance payments as set forth in any addendum to this
Agreement then in effect or, if such addendum does not designate severance
payments, severance payments at the annual rate of $100,000 for the then
remaining term of this Agreement as if this Agreement had not been terminated.
Neither the Executive nor the Executive's estate will be entitled to any bonus
or form of employee benefit plan, including, without limitation, life, health,
dental and disability insurance, or the payment of monies in lieu thereof.  The
severance payments provided pursuant to this Section 3.4 will be paid at such
times and in such manner as stated in the addendum to this Agreement or if not
so stated as payments normally would be made under Section 2 and will be subject
to deductions and withholding as provided in Section 2.  Notwithstanding
anything in this Agreement to the contrary, the Company will have no obligation
to continue any payments due the Executive, and the Executive will not have any
right to receive such payments, if the Company determines in good faith that the
Executive has breached the covenants in Sections 4 or 5 of this Agreement.  In
addition, the Company's obligation to make such severance payments to the
Executive under this Agreement is conditioned upon the Executive's (or his
estate's) execution and delivery to the Company of a release (in form and
substance reasonably satisfactory to the Company) of any and all claims known to
the Executive (or his estate) that the Executive (or his estate) may have
against the Company or any officer, director or Affiliate of the Company (as
defined in Section 4.1(a)) at any time up to and including the date of
termination and arising thereafter, excluding the Company's obligation to make
the severance payments.

     3.5  Survival.  The obligations of the Executive pursuant to Sections 4, 5
          --------                                                             
and 6 survive the termination of this Agreement.

                                   SECTION 4
                                 RESTRICTIONS

          --------                                                       
Sections 4 and 5 of this Agreement are of the essence of this Agreement; that
each of the covenants is reasonable and necessary to protect the business,
interests and properties of the Company; and that irreparable loss and damage
may be suffered by the Company should he breach any of such covenants.  The
Executive agrees and consents that, in addition to all the remedies provided by
law or in equity, so long as the Company is otherwise entitled thereto under
applicable law, the Company will be entitled to a temporary restraining order
and temporary and permanent injunctions to prevent a breach or threatened breach
of the covenants prohibiting disclosure of any Proprietary Technology without
the need for posting bond for temporary injunctions or interlocutory
injunctions.  The Company and the Executive agree that all remedies available to
the Company or Executive, as applicable, will be cumulative.

     6.2  Right to Set-Off.  The Company will have the right to set-off against
          ----------------

Company as a result of any breach of this Agreement by the Executive to the
extent allowed under applicable law.  Any application as a set-off of such
amounts against the damages incurred or suffered by the Company as a result of
any breach of this Agreement by the Executive will not be considered in full
satisfaction of or as liquidated damages for or a release of any claims for
damages against the Executive that may accrue to the Company as a result of any
breach of this Agreement by the Executive.

     6.3  Resolution of Disputes on Determination of Cause and Breach of
          --------------------------------------------------------------
Restrictive Covenants.  The parties agree that any controversy or dispute
- ---------------------                                                    
regarding whether or not "cause" exists for termination of the Executive's
employment under this Agreement or any determination that the restrictive
covenants and nondisclosure covenants of Sections 4 and 5 have been breached
(each, a "Dispute") that is not resolved by the parties within a reasonable
amount of time may be submitted to binding arbitration administered by the
American Arbitration Association ("AAA") under its Commercial Arbitration Rules,
except where those rules are supplemented or modified by the express terms of
this section.  The parties agree that binding arbitration is the exclusive
remedy for resolving any Dispute, except for the right of either party to pursue
injunctive relief pursuant to Section 6.1.  Either party may initiate
arbitration by

                                      -8-
<PAGE>
 
sending notice of its intention to arbitrate the Dispute to the other party,
which notice must be accompanied by a brief setting forth the nature of the
Dispute and the grounds for the existence or non-existence of "cause" or any
breach of the restrictive covenants and nondisclosure covenants of Sections 4
and 5, as the case may be, and the remedy sought, which brief may not exceed 25
typed pages (the "Arbitration Notice").  The party demanding arbitration must
also file at the regional office of the AAA three copies of the Arbitration
Notice and Brief and the arbitration provision of this Agreement together with
the required filing fee.  The other party to the arbitration must file a
responsive brief within 15 business days of receipt of the demanding party's
Arbitration Notice and Brief, which responsive brief may not exceed 25 typed
pages.  Any arbitration proceedings will be in Washington, D.C.  If the parties
are able to agree on one arbitrator within 15 days of the date the Arbitration
Notice is filed with the AAA, the Dispute will be heard by that arbitrator.  If
the parties are unable to agree on one arbitrator, then an arbitrator will be
selected from an impartial roster of arbitrators provided by the AAA in
accordance with the AAA rules.  There will be no discovery permitted by the
parties in the arbitration proceedings provided that each party will be
permitted to take one oral deposition of the other party or unless otherwise
mutually agreed to by the parties.  The Company agrees to be bound by Rule
30(b)(6) of the Federal Rules of Civil Procedures "Deposition of an
Organization," as amended from time to time or any successor rule.  The
arbitrator will issue a decision within 30 days of his or her appointment.  The
decision of the arbitrator must set forth in reasonable detail the reasoning
supporting the decision of the arbitrator.  The decision rendered by the
arbitrator will be final and binding on the parties and judgment on the decision
rendered by the arbitrator may be entered in any court having jurisdiction.
Each party will pay its own costs and expenses related to the arbitration
procedures.  This agreement to arbitrate will survive the termination of this
Agreement and is specifically enforceable under the prevailing arbitration law
and survives the termination of this Agreement.  Any attempted termination of
this Agreement that results in a Dispute submitted to arbitration will suspend
the termination of this Agreement until resolved by the arbitrator.  The parties
further agree that the Company will be entitled to pursue any available
temporary restraining orders or other injunctive relief notwithstanding any
pending arbitration or request for arbitration by the Executive or the Company.

of this Agreement, and that the invalidity or unenforceability of any Agreement
provision will not affect the validity or enforceability of any other provision

              FIRST AMENDMENT TO THE EMPLOYMENT AGREEMENT BETWEEN
                 CENTURY SERVICES, INC. AND MICHAEL C. HIGGINS

     THIS FIRST AMENDMENT is made on May 21, 1997, between CENTURY SERVICES,
INC., a Maryland corporation (the "Company"), and Michael C. Higgins, an
individual resident of the State of Maryland (the "Executive").

                                   BACKGROUND

     The Company and the Executive entered into an employment agreement (the
"Agreement") on November 6, 1996.

     The Company and the Executive now desire to amend the Agreement to provide
for an annual base salary schedule and a bonus of fifty percent of base salary
to be paid twenty-five percent in cash and seventy-five percent in shares of
common stock, par value $.001, of the Company (the "Common Stock").

     The Company and the Executive also desire to amend the Agreement to allow
the Compensation Committee of the Company the discretion to award any or all of
the bonus in the event the Executive does not attain the performance criteria or
is terminated by the Company before the end of the year in which the Executive
is to be paid and to remove restrictions in the Agreement that prevent the
Executive from receiving incentives under the incentive plans maintained by the
Company.

                                   AMENDMENT

     NOW, THEREFORE, the parties agree that the Agreement is amended, effective
January 1, 1997, as follows:

1.   By deleting Section 2.1 in its entirety and substituting the following:

          "2.1  Cash Compensation.  For all services to be rendered by the

     following amounts, which payment will be subject to withholdings for local,
     state and federal taxes, social security, and other deductions required by
     law or the policies of the Company, from time to time in effect:

          gross salary (the "Base Salary") for each fiscal year of the Company
          at the following annual rates:

                  <S>          <C>
 
                       1997       $150,000
                       1998       $175,000
                       1999       $200,000
</TABLE>
<PAGE>
 
               The Base Salary will be payable on the Company's standard salary
          payment schedule for executive level employees.

               (b)  Bonus.  For each of fiscal year 1997, 1998, and 1999, if the
                    -----                                                       
          Executive remains an employee of the Company on the last day of such
          fiscal year, Executive will be eligible to receive a bonus of 100
          percent of Base Salary if he achieves all performance criteria
          established by the Compensation Committee of the Company.  Each bonus
          will be payable as soon as administratively feasible after the
          Company's audited financial statements for the applicable fiscal year
          become available.  The performance criteria for fiscal year 1997 have
          been established as follows: (1) if the Company attains gross revenues
          of at least $9 million as shown in the Company's audited financial
          statements, the Executive will receive a bonus of fifty percent (50%)
          of Base Salary, and in addition, (2) if the Company attains net income
          before interest, taxes, and amortization (EBITA) of $200,000 as shown
          in the Company's audited financial statements, the Executive will
          receive an additional bonus of fifty percent (50%) of Base Salary.
          Such bonus for 1997 will be payable twenty-five percent (25%) in cash
          and seventy-five percent (75%) in shares of common stock, par value
          $.001, of the Company ("Common Stock").  The number of shares of
          Common Stock the Executive will receive pursuant to the bonus formula
          will be equal to (a) the dollar amount of the bonus payable in the
          form of shares of Common Stock divided by (b) the average trade price
          per share of Common Stock over the last ten trading days of the fiscal
          year for which the shares of Common Stock are granted.  In the event
          the Executive does not achieve the performance criteria, or any part
          thereof, for the fiscal year, the Compensation Committee of the
          Company will have the authority and discretion to award the bonus, or
          any part thereof.  The Compensation Committee of the Company may, in
          its discretion, award the Executive the bonus, or any part thereof, in
          the event the Executive is terminated by the Company prior to the end
          of a fiscal year.  For fiscal years 1998 and 1999, the Compensation
          Committee of the Company will, no later than 90 days after the
          beginning of the fiscal year, set new performance criteria and
          establish the percentage of the bonus for such year to be paid in cash
          or shares of Common Stock and will promptly communicate the
          performance criteria and the payment percentages to the Executive,
          thereafter.

2.   By adding the following before the period (".") at the end of the first
sentence of Section 3.4:

     ";provided, however, that such payments will be reduced by any severance,
     life insurance, or disability payments to the Executive, his beneficiary,
     or estate that are provided under any plan, program, or policy of the
     Company or an affiliate, except to the extent the premiums associated with
     such payments were paid by the Executive."

     Except as specifically provided herein, the Agreement will remain in full
force and effect as prior to this First Amendment.

     The parties have caused this First Amendment to be executed as of the day
and year first above written.

Company) of any and all claims known to the Executive (or his estate) that the
Executive (or his estate) may have against the Company or any officer, director

          --------                                                       
Sections 4 and 5 of this Agreement are of the essence of this Agreement; that

extent allowed under applicable law.  Any application as a set-off of such
amounts against the damages incurred or suffered by the Company as a result of
any breach of this Agreement by the Executive will not be considered in full
satisfaction of or as liquidated damages for or a release of any claims for
damages against the Executive that may accrue to the Company as a result of any
breach of this Agreement by the Executive.

     6.3  RESOLUTION OF DISPUTES ON DETERMINATION OF CAUSE AND BREACH OF
          --------------------------------------------------------------
RESTRICTIVE COVENANTS.  The parties agree that any controversy or dispute
- ---------------------                                                    
regarding whether or not "Cause" exists for termination of the Executive's
employment under this Agreement or any determination that the restrictive
covenants and nondisclosure covenants of Sections 4 and 5 have been breached
(each, a "Dispute") that is not resolved by the parties within a reasonable
amount of time may be submitted to binding arbitration administered by the
American Arbitration Association ("AAA") under its Commercial Arbitration Rules,
except where those rules are supplemented or modified by the express terms of
this section.  The parties agree that binding arbitration is the exclusive
remedy for resolving any Dispute, except for the right of either party to pursue
injunctive relief pursuant to Section 6.1.  Either party may initiate
arbitration by sending notice of its intention to arbitrate the Dispute to the
other party, which notice must be accompanied by a brief setting forth the
nature of the Dispute and the grounds for the existence or non-existence of
"Cause" or any breach of the restrictive covenants and nondisclosure covenants
of Sections 4 and 5, as the case may be, and the remedy sought, which brief may
not exceed 25 typed pages (the "Arbitration Notice").  The party demanding
arbitration must also file at the regional office of the AAA three copies of the
Arbitration Notice and Brief and the arbitration provision of this Agreement
together with the required filing fee.  The other party to the arbitration must
file a responsive brief within 15 business days of receipt of the demanding
party's Arbitration Notice and Brief, which responsive brief may not exceed 25
typed pages.  Any arbitration proceedings will be in Washington, D.C.  If the
parties are able to agree on one arbitrator within 15 days of the date the
Arbitration Notice is filed with the AAA, the Dispute will be heard by that
arbitrator.  If the parties are unable to agree on one arbitrator, then an
arbitrator will be selected from an impartial roster of arbitrators provided by
the AAA in accordance with the AAA rules.  There will be no discovery permitted
by the parties in the arbitration proceedings provided that each party will be
permitted to take one oral deposition of the other party or unless otherwise
mutually agreed to by the parties.  The Company agrees to be bound by Rule
30(b)(6) of the Federal Rules of Civil Procedures "Deposition of an
Organization," as amended from time to time or any successor rule.  The
arbitrator will issue a decision within 30 days of his or her appointment.  The
decision of the arbitrator must set forth in reasonable detail the reasoning
supporting the decision of the arbitrator.  The decision rendered by the
arbitrator will be final and binding on the parties and judgment on the decision
rendered by the arbitrator may be entered in any court having 

                                       10
<PAGE>
 
jurisdiction. Each party will pay its own costs and expenses related to the
arbitration procedures. This agreement to arbitrate will survive the termination
of this Agreement and is specifically enforceable under the prevailing
arbitration law and survives the termination of this Agreement. Any attempted
termination of this Agreement that results in a Dispute submitted to arbitration
will suspend the termination of this Agreement until resolved by the arbitrator.
The parties further agree that the Company will be entitled to pursue any
available temporary restraining orders or other injunctive relief
notwithstanding any pending arbitration or request for arbitration by the
Executive or the Company.

of this Agreement, and that the invalidity or unenforceability of any Agreement
provision will not affect the validity or enforceability of any other provision
of this Agreement.  Further, if any provision of this Agreement is ruled invalid

between the provision and any applicable law or public policy, the provision
will be redrawn to make the provision consistent with and valid and enforceable
under the law or public policy.

Company agrees to take the following actions:

         (a) Separation Payment.  The Company agrees to pay the Executive a

effect for himself and his dependents by exercise of his rights under the
Consolidated Omnibus Budget Reconciliation Act of 1986 ("COBRA") for the period

             --------------------                                           
agreement with the Executive in substantially the form of the Consulting
Agreement attached hereto as Exhibit A (the "Consulting Agreement").

continue those medical and dental coverages which are then currently available
to the Company's employees generally by making monthly payments for such
coverages to the Company, subject to such terms and conditions as apply to any
former employee entitled to exercise his or her COBRA rights.  Executive
acknowledges that the 18-month continuation period for these coverages commences
April 22, 1997.  Executive understands and agrees that Executive's coverages
under the Company's other "welfare plans," within the meaning of Section 3(1) of

out and is being held in escrow pursuant to an Earn Out Stock Escrow Agreement
dated November 6, 1996 among ZMAX, the Executive, Michael C. Higgins ("Higgins")

                              CONSULTING AGREEMENT


     THIS CONSULTING AGREEMENT (this "Agreement") is made on May 30, 1997,
between ZMAX CORPORATION, a Nevada corporation (the "Company"), and WAREHAM
MANAGEMENT LTD., a company organized under the laws of British Columbia, Canada
(the "Consultant").

                                   AGREEMENT

     In consideration of the above and the retention of the Consultant by the
Company, and the mutual agreements hereinafter set forth, the parties agree as
follows:

     1.   Engagement as a Consultant.  The Company hereby retains the
          --------------------------                                 
Consultant, and the Consultant hereby accepts such engagement by the Company,
upon the terms and conditions of this Agreement.

     2.   Duties.  The Consultant is engaged to be available on a reasonable,
          ------                                                             
on-call basis to provide consulting services related to accounting and financial
matters of the Company, as described in Exhibit A the ("Services").  The
                                        ---------                       
Consultant agrees to perform and discharge well and faithfully all Services as
the Company reasonably may request from time to time.  The Consultant will hold
in trust for the Company all funds and property it receives on behalf of the
Company, and will account for and remit all such funds to the Company, as
applicable.  The Consultant will report to the Board of Directors of the
Company.  Unless otherwise agreed to by the Company, all Services to be
performed by the Consultant hereunder will be performed on behalf of the
Consultant exclusively by Mr. G.W. Norman Wareham, the President of the
Consultant, and Consultant will make Mr. Wareham available therefor.  The
Consultant agrees to cause Mr. Wareham to serve, and Mr. Wareham agrees to
serve, without additional compensation, in the corporate positions to which he
may be elected or appointed by which the Company or its Board of Directors,
which the parties agree will not establish an employment relationship between
the Company and Mr. Wareham.  Throughout the term of the Consultant's engagement
hereunder, the Consultant will devote the time necessary to perform the Services
but will not be required to devote its services on a full-time or exclusive
basis, so long as Consultant is performing its assigned or requested duties
under this Agreement.

     3.   Compensation.  As compensation for the Services, the Company will pay
          ------------                                                         
to the Consultant the amount of U.S. $3,500.00 per month plus seven percent (7%)
to cover Canadian General Sales Tax (the "Consulting Fee"), payable on the first
business day of each month.  The Consultant will receive no compensation in
addition to that set forth in this Agreement for any Services rendered to the
Company unless otherwise agreed to by the Company.

     4.   Reimbursement of Expenses.  The Consultant will be entitled to be
          -------------------------                                        
reimbursed in accordance with the policies of the Company, as adopted and
amended from time to time, for
<PAGE>
 
all reasonable and necessary expenses incurred by him in connection with the
performance of Services pursuant to this Agreement; provided that the Consultant
will, as a condition of such reimbursement, submit acceptable verification of
the nature and amount of such expenses in accordance with the reimbursement
policies from time to time adopted by the Company.

     5.   Term and Termination.  The term of the engagement of the Consultant by
          --------------------                                                  
the Company will commence on the date of this Agreement and will continue for
one (1) year thereafter (the "Term"), unless sooner terminated as provided
herein.  At the end of each expiring Term, the Term shall automatically renew
for an additional year, unless either the Consultant or the Company gives notice
of termination.  The Company or the Consultant may terminate this Agreement with
or without cause on thirty (30) days notice to the other.  Upon the termination
of the Consultant's engagement hereunder, the Company will have no further
obligation to the Consultant, except that the Company will pay to the Consultant
any compensation and reimbursement accrued up to the date of termination
hereunder and unpaid on such date of termination.

     6.   Agreement Not to Compete or Solicit Customers.

engagement hereunder and for two (2) years after the termination of this

or any consultant or contractor of the Company or an Affiliate.

     8.  Ownership and Protection of Confidential Information and Trade Secrets.
         ---------------------------------------------------------------------- 

         (a)  Definitions.  "Confidential Information" means data and
              -----------                                            
information relating to the business of the Company or an Affiliate (which does
not rise to the status of a Trade Secret) that is or has been disclosed to the
Consultant by the Company or an Affiliate or of which the Consultant became
aware as a consequence of or through its relationship to the Company, which has
value to the Company and is not generally known to its competitors.
Confidential Information will not include any data or information that has been
voluntarily disclosed to the public by the Company (except where such public
disclosure has been made by the Consultant without authorization) or that has
been independently developed and disclosed by others, or that otherwise enters
the public domain through lawful means.  "Trade Secrets" means information,
including a formula, pattern, compilation, program, device, method, technique,
or process that:  (i) derives independent economic value, actual or potential,
from not being generally known to, and not being readily ascertainable by proper
means by, other persons who can obtain economic value from its disclosure or
use, and (ii) is the subject of efforts that are reasonable under the
circumstances to maintain its secrecy.

          (b) Confidentiality.  All Confidential Information and Trade Secrets
              ---------------                                                 
and all physical embodiments thereof received or developed by the Consultant
while engaged by the Company or an Affiliate are confidential to and are and
will remain the sole and exclusive property of the Company or Affiliate.  Except
to the extent necessary to perform the duties assigned by the Company or an
Affiliate, the Consultant and Mr. Wareham will hold such Confidential
Information and Trade Secrets in trust and strictest confidence, and will not
use, reproduce, distribute, disclose or otherwise disseminate the Confidential
Information and Trade Secrets or any physical embodiments thereof and may in no
event take any action causing or fail to take the action necessary in order to
prevent, any Confidential Information and Trade Secrets disclosed to or
developed by the Consultant to lose its character or cease to qualify as
Confidential Information or Trade Secrets.

                                      -3-

          (c) Return of Company Property.  Upon request by the Company or an
              --------------------------                                    
Affiliate, and in any event upon termination of the engagement of the Consultant
with the Company or an Affiliate for any reason, as a prior condition to
receiving any final fees or reimbursement hereunder (including any payments
pursuant to Section 3 hereof), the Consultant will promptly deliver to the
Company or an Affiliate all property belonging to the Company or an Affiliate,
including, without limitation, all Confidential Information and Trade Secrets
(and all embodiments thereof) then in the Consultant's or Mr. Wareham's custody,
control or possession.

          (d) Survival.  The covenants of confidentiality set forth herein will

apply on and after the date hereof to any Confidential Information and Trade
Secrets disclosed by the Company or an Affiliate, or developed by the Consultant
prior to or after the date hereof.  The covenants restricting the use of
Confidential Information will continue and be maintained by the Consultant for a
period of two (2) years following the termination of this Agreement.  The
covenants restricting the use of Trade Secrets will continue and be maintained
by the Consultant following termination of this Agreement for so long as
permitted by the Maryland Uniform Trade Secrets Act.

     9.   Remedies.  The Consultant and Mr. Wareham agree that the covenants and
          --------                                                              
agreements contained in Sections 6, 7, and 8 hereof are of the essence of this
Agreement; that each of such covenants is reasonable and necessary to protect
and preserve the interests and properties of the Company and the Business of the
Company; that the Company is engaged in the Business of the Company worldwide;
that irreparable loss and damage will be suffered by the Company should the
Consultant or Mr. Wareham breach any of such covenants and agreements; that each
of such covenants and agreements is separate, distinct and severable not only
from the other of such covenants and agreements but also from the other and
remaining provisions of this Agreement; that the unenforceability of any such
covenant or agreement will not affect the validity or enforceability of any
other such covenant or agreements or any other provision or provisions of this
Agreement; and that, in addition to other remedies available to it, the Company
will be entitled to specific performance of this Agreement and to both temporary
and permanent injunctions to prevent a breach or contemplated breach by the
Consultant or Mr. Wareham of any of such covenants or agreements.

     10.  No Set-Off.  The existence of any claim, demand, action or cause of
          ----------                                                         
action by the Consultant or Mr. Wareham against the Company or any Affiliate,
whether predicated upon this Agreement or otherwise, will not constitute a
defense to the enforcement by the Company of any of its rights hereunder.  The
existence of any claim, demand, action or cause of action by the Company against
the Consultant or Mr. Wareham, whether predicated upon this Agreement or
otherwise, will not constitute a defense to the enforcement by the Consultant of
any of its rights hereunder; provided, however, that the Company will have the
right to discontinue payments to the Consultant under Section 3(e) hereof, as
applicable, if the Consultant or Mr. Wareham should breach any of their
obligations under Sections 6, 7, or 8 hereof and the Company notifies the
Consultant of that breach.

of the Company.  Throughout the term of the Consultant's engagement hereunder,
the Consultant will devote the time necessary to perform the Services but will
not be required to devote his services on a full-time basis, so long as, in the

property he receives on behalf of the Company, and he will account for and remit
all such funds to the Company, as applicable.

     3.   Compensation.  As compensation for the Services, the Company will pay
          ------------

compensation in addition to that set forth in this Agreement for any Services
rendered by him to the Company unless otherwise agreed to by the Company.

     4.   Reimbursement of Expenses.  The Consultant will be entitled to be
          -------------------------

amended from time to time, for all reasonable and necessary expenses incurred by
him in connection with the performance of the Services pursuant to this
Agreement; provided that the Consultant will, as a condition of such
reimbursement, submit acceptable verification of the nature and amount of such
expenses in accordance with the reimbursement policies from time to time adopted
by the Company.

     5.   Term and Termination.  The term of the engagement of the Consultant by

one (1) year

thereafter (the "Term"), unless sooner terminated as provided herein.  At the
end of each expiring Term, the Term shall automatically renew for an additional
year, unless either the Consultant or the Company gives notice of termination.
The Company or the Consultant may terminate this Agreement with or without cause
on thirty (30) days notice to the other.  Upon the termination of the
Consultant's engagement hereunder, the Company will have no further obligation
to the Consultant, except that the Company will pay to the Consultant any
compensation and reimbursement accrued up to the date of termination hereunder
and unpaid on such date of termination.

engagement hereunder and for two (2) years after the termination of this

withheld in Company's sole discretion), either directly or indirectly, on his or
another's behalf, (i) engage in (as a director, officer, principal, partner,

          (b) Agreement Not to Solicit Customers.  The Consultant agrees that
              ----------------------------------

behalf or in the service of or on behalf of others, solicit, divert or hire
away, or attempt to solicit, divert or hire away, to any Competing Business any
person employed by the Company or an Affiliate, whether or

             -----------                                            
information relating to the business of the Company or an Affiliate (which does
not rise to the status of a Trade Secret) that is or has been disclosed to the
Consultant by the Company or an Affiliate or of which the Consultant became
aware as a consequence of or through his relationship to the Company, which has
value to the Company and is not generally known to its competitors.
Confidential Information will not include any data or information that has been
voluntarily disclosed to the public by the Company (except where such public
disclosure has been made by the Consultant without authorization) or that has
been independently developed and disclosed by others, or that otherwise enters
the public domain through lawful means.  "Trade Secrets" means information,
including a formula, pattern, compilation, program, device, method, technique,
or process that:  (i) derives independent economic value, actual or potential,
from not being generally known to, and not being readily ascertainable by proper
means by, other persons who can obtain economic value from its disclosure or
use, and (ii) is the subject of efforts that are reasonable under the
circumstances to maintain its secrecy.

          (b) Confidentiality.  All Confidential Information and Trade Secrets
              ---------------                                                 
and all physical embodiments thereof received or developed by the Consultant
while engaged by the Company or an Affiliate are confidential to and are and
will remain the sole and exclusive property of the Company or Affiliate.  Except
to the extent necessary to perform the duties assigned by the Company or an
Affiliate, the Consultant will hold such Confidential Information and Trade
Secrets in trust and strictest confidence, and will not use, reproduce,
distribute, disclose or otherwise disseminate the Confidential Information and
Trade Secrets or any physical embodiments thereof and may in no event take any
action causing or fail to take the action necessary in order to prevent, any
Confidential Information and Trade Secrets disclosed to or developed by the
Consultant to lose its character or cease to qualify as Confidential Information
or Trade Secrets.

          (c) Return of Company Property.  Upon request by the Company or an
              --------------------------                                    
Affiliate, and in any event upon termination of the engagement of the Consultant
with the Company or an Affiliate for any reason, as a prior condition to
receiving any final fees or reimbursement hereunder (including any payments
pursuant to Section 3 hereof), the Consultant will promptly deliver to the
Company or an Affiliate all property belonging to the Company or an Affiliate,
including, without limitation, all Confidential Information and Trade Secrets
(and all embodiments thereof) then in the Consultant's custody, control or
possession.

          (d) Survival.  The covenants of confidentiality set forth herein will

apply on and after the date hereof to any Confidential Information and Trade
Secrets disclosed by the Company or an Affiliate, or developed by the Consultant
prior to or after the date hereof.  The

                                      -3-
<PAGE>
 
covenants restricting the use of Confidential Information will continue and be
maintained by the Consultant for a period of two (2) years following the
termination of this Agreement.  The covenants restricting the use of Trade
Secrets will continue and be maintained by the Consultant following termination
of this Agreement for so long as permitted by the Maryland Uniform Trade Secrets
Act.

     9.   Remedies.  The Consultant agrees that the covenants and agreements
          --------                                                          
contained in Sections 6, 7 and 8 hereof are of the essence of this Agreement;
that each of such covenants is reasonable and necessary to protect and preserve
the interests and properties of the Company and the Business of the Company
worldwide; that the Company is engaged in the Business of the Company; that
irreparable loss and damage will be suffered by the Company should the
Consultant breach any of such covenants and agreements; that each of such
covenants and agreements is separate, distinct and severable not only from the
other of such covenants and agreements but also from the other and remaining
provisions of this Agreement; that the unenforceability of any such covenant or
agreement will not affect the validity or enforceability of any other such
covenant or agreements or any other provision or provisions of this Agreement;
and that, in addition to other remedies available to it, the Company will be
entitled to specific performance of this Agreement and to both temporary and
permanent injunctions to prevent a breach or contemplated breach by the
Consultant of any of such covenants or agreements.

action by the Consultant against the Company or any Affiliate, whether
predicated upon this Agreement or otherwise, will not constitute a defense to
the enforcement by the Company of any of its rights hereunder.  The existence of
any claim, demand, action or cause of action by the Company against the
Consultant, whether predicated upon this Agreement or otherwise, will not
constitute a defense to the enforcement by the Consultant of any of its rights
hereunder; provided, however, that the Company will have the right to
discontinue payments to the Consultant under Section 3 hereof, as applicable, if
the Consultant should breach any of its obligations under Sections 6, 7 or 8
hereof, and the Company notifies the Consultant of that breach.

     11.  Notice.  All notices, requests, demands and other communications
          ------

                        EARN OUT STOCK ESCROW AGREEMENT

          THIS EARN OUT STOCK ESCROW AGREEMENT (this "Agreement") is made on
November 6, 1996, among ZMAX CORPORATION, a Nevada corporation ("ZMAX"); Michael
C. Higgins and Michael S. Cannon (collectively, the "Stockholders" and
individually, a "Stockholder"); and Powell, Goldstein, Frazer & Murphy ("Escrow
Agent").

                                  BACKGROUND:

          ZMAX and the Stockholders have agreed that ZMAX is acquiring all
outstanding capital stock, par value $1.00 (the "CSI Stock") of Century
Services, Inc., a Maryland corporation ("CSI") by the Corporation, pursuant to
the terms and conditions of the Stock Purchase Agreement dated the same date as
this Agreement, among ZMAX and the Stockholders (the "Acquisition Agreement").
The transactions contemplated by the Acquisition Agreement are referred to as
the "Transaction."

          In accordance with the Acquisition Agreement, ZMAX will issue
3,200,000 shares of ZMAX common stock, par value $0.001 (the "ZMAX Stock") to
the Stockholders in exchange for their shares of CSI Stock.

          2,800,000 of the 3,200,000 shares of ZMAX Stock (the "Earn Out Stock")
are subject to earn out on the terms and conditions set forth in the Acquisition
Agreement.

          The parties have agreed to place the Earn Out Stock into escrow to be
released on the terms and conditions set forth in the Acquisition Agreement and
below.

          In consideration of the mutual representations, warranties, covenants
and agreements contained in this Agreement, the parties agree as follows:

                              STATEMENT OF TERMS:

          1.  Definitions.  All capitalized terms used in this Agreement and not

otherwise defined herein shall have the meanings assigned to such terms in the
Acquisition Agreement.

          2.  Appointment of Escrow Agent.  ZMAX and the Stockholders appoint
              ---------------------------                                    
Powell, Goldstein, Frazer & Murphy as Escrow Agent, and Escrow Agent agrees to

              ----------------------------------------------                    
to Escrow Agent two stock certificates evidencing the issuance of 1,400,000
share of ZMAX Stock to each Stockholder.  Escrow Agent will hold such stock
certificates in its vault and will release them only pursuant to the terms and
conditions of this Agreement.
<PAGE>
 
      4.  Procedures for Release of Stock.
          ------------------------------- 

          4.1  Receipt of Cash Flow Statement; Notice to Transfer Agent.  During

the term of this Agreement, upon receipt by Escrow Agent of either (i) a Cash
Flow Statement (as defined in the Acquisition Agreement) signed as approved by
ZMAX and each Stockholder pursuant to Section 1.5 or 1.6 of the Acquisition
Agreement or (ii) instructions jointly signed by ZMAX and the Stockholders or a
court or arbitration order as to the Cash Flow of CSI for a particular period,
Escrow Agent will deliver the ZMAX stock certificates held by it to ZMAX's
transfer agent ("Transfer Agent") and instruct Transfer Agent to replace each
stock certificate with (i) one new stock certificate evidencing the number of
shares of ZMAX Stock to be released to the Stockholder as described in the Cash
Flow Statement or other instructions and (ii) a second new stock certificate
evidencing the number of shares remaining, if any, after deducting the shares
being released as described in the Cash Flow Statement or other instructions,
which remaining shares will continue to be designated as Earn Out Stock and
remain subject to this Agreement.  Escrow Agent will further instruct the
Transfer Agent to deliver the first new certificate to the Stockholder and the
second new certificate to Escrow Agent and to legend all stock certificates in
accordance with the Stockholders Agreement between ZMAX and the Stockholders;
provided, however, that until August 6, 1997, the first new certificate will be
delivered to ZMAX in accordance with the Stock Pledge and Security Agreement
between each Stockholder and ZMAX dated as of the date of this Agreement.

          4.2  Notice of Termination of Earn Out.  Upon receipt by Escrow Agent
               ---------------------------------

Stockholder has been terminated by CSI for cause (as defined in the
Stockholder's employment agreement with CSI) or has violated his non-
competition, non-solicitation or proprietary information restrictions contained
in his employment agreement with CSI, Escrow Agent will promptly fax a copy of
the officer's certificate to the affected Stockholder.  Unless, within 10
business days of Escrow Agent's sending such fax, Escrow Agent receives notice
from the Stockholder that he disputes the termination or breach of his
employment agreement, Escrow Agent will deliver to ZMAX the stock certificate of
the Stockholder held by Escrow Agent.  If Escrow Agent receives a dispute notice
from the Stockholder, Escrow Agent will continue holding the stock certificate
of the Stockholder until it receives joint instructions from ZMAX and the
Stockholder or court or arbitration order.

          4.3  Delivery Method.  All documents and stock certificates delivered
               ---------------

or other recognized overnight courier service that provides receipt of delivery.

      5.  Notice of Accounting Firm.  ZMAX will promptly notify Escrow Agent
          -------------------------                                         
if the independent accounting firm serving CSI is changed.

      6.  Rights and Duties of Escrow Agent.
          --------------------------------- 

          6.1   Escrow Agent will not be liable for any actions taken or omitted
upon the advice of counsel or upon a reasonable interpretation of any
instructions or documents provided to it by ZMAX or the Stockholders that it
reasonably believes to be genuine or duly authorized.  Escrow Agent may decline
to act if it is in doubt as to its duties under this Agreement and shall not be
liable for such failure to act.  Notwithstanding references herein to the
Acquisition Agreement, Escrow Agent will not be charged with, nor be deemed to
have knowledge of, any terms or conditions thereof, and Escrow Agent will not be
under any duty to make any investigation of facts reported to it thereunder.

          6.2  If Escrow Agent shall incur any liability, damage or expense
arising out of or resulting from any claim that Escrow Agent has improperly
distributed any of the Closing Documents under this Agreement, other than as a
result of Escrow Agent's gross negligence or willful misconduct, ZMAX and the
Stockholders (collectively, the "Indemnitor") shall indemnify and hold Escrow
Agent harmless therefrom.  Escrow Agent is not responsible for the genuineness
of any signature and may rely conclusively upon, and shall be protected in
acting upon, any list, advice, judicial order or decree, certificate, notice,
request, consent, statement, instruction or other instrument believed by it in
good faith to be genuine or to be signed or presented by the proper party, or
duly authorized or properly made.

          6.3  Escrow Agent is not responsible for any of the agreements
described herein except for the performance of its duties as expressly set forth
herein.  Escrow Agent's duties and obligations hereunder will be governed solely
by the provisions of this Agreement, and Escrow Agent shall not have any duties
other than the duties expressly imposed herein and shall not be required to take
any action other than in accordance with the terms of this Agreement.

          6.4  Escrow Agent will not be bound by any notice of, or demand with
respect to, any waiver, modification, amendment, termination, cancellation,
rescission or other action under or with respect to this Agreement, unless duly
executed by ZMAX and the Stockholders and, if Escrow Agent's rights or duties
are affected thereby, unless Escrow Agent has given its prior written consent
thereto.

          6.5  In the event of any controversy or dispute hereunder, or with
respect to any question as to the construction of this Agreement, or any action
to be taken by Escrow Agent hereunder, Escrow Agent will incur no liability for
any action taken or omitted in good faith in accordance with the advice and the
opinion of its counsel or its own reasonable judgment.  In the event of any
controversy or dispute hereunder, or with respect to any question as to the
construction of this Agreement, or any action to be taken by Escrow Agent
hereunder, Escrow Agent may request joint written instructions signed by ZMAX
and both Stockholders and/or may seek advice of counsel or commence an
interpleader action or seek any other appropriate relief from a court of
competent jurisdiction.  ZMAX and the Stockholders each consent to jurisdiction
and venue in such court.  If Escrow Agent deems it necessary to seek

                                      -3-
<PAGE>
 
advise of counsel under this Section 6.5, ZMAX and the Stockholders will
reimburse Escrow Agent for the actual and reasonable costs of such counsel.

              6.6  Escrow Agent's liability under this Agreement will be limited
solely to gross negligence or willful misconduct on its part.

              6.7  The parties acknowledge that Escrow Agent is a law firm
currently representing ZMAX in the Transaction. ZMAX and the Stockholders agree
that this Agreement and the performance of the terms thereof by Escrow Agent
will not act in any manner to disqualify the law firm of Powell, Goldstein,
Frazer & Murphy from continuing its representation of ZMAX in the Transaction or
the contemplated engagement of Powell, Goldstein, Frazer & Murphy by CSI after
the Transaction is completed. ZMAX and the Stockholders, each having advice of
separate counsel, hereby waive conflict, if any, created by Escrow Agent
simultaneously serving as escrow agent under this Agreement any in such
representation of ZMAX and/or CSI. The parties further acknowledge that Escrow
Agent is entitled to reimbursement of its costs and expenses and the standard
hourly fees of attorneys in its firm that assist in performing the duties of
Escrow Agent under this Agreement, which amounts will be billed by Escrow Agent
to ZMAX.

          7.  Termination.  This Agreement shall terminate upon the date on
              -----------                                                  
which all Earn Out Shares have been delivered to the Stockholders.

          8.  Governing Law.  This Agreement shall be governed by and construed
              -------------                                                    
in accordance with the laws of the District of Columbia.

          9.  Assignment.  This Agreement shall be binding upon and inure to the
              ----------                                                        
benefit of the parties hereto and their respective heirs, legal representatives,
successors and assigns.

          10. No Third Party Beneficiaries.  None of the provisions of this
              ----------------------------                                 
Agreement is or shall be construed as for the benefit of or enforceable by any
person not a party to this Agreement.

          11. Notice.  Any notice required to be given hereunder shall be in
              ------

                                ZMAX CORPORATION
                             STOCKHOLDERS AGREEMENT

     THIS STOCKHOLDERS AGREEMENT (this "Agreement") is made on November 6, 1996,
among MICHAEL C. HIGGINS and MICHAEL S. CANNON (collectively, the "Stockholders"
and each individually, a "Stockholder") and ZMAX CORPORATION, a Nevada
corporation (the "Corporation").

                                  BACKGROUND:

     The Stockholders presently own shares of the Corporation's authorized
common stock, par value $0.001 (the "Stock").

     The Stock owned by the Stockholders was acquired as part of the acquisition
of Century Services, Inc., a Maryland corporation ("CSI"), by the Corporation,
pursuant to the Stock Purchase Agreement dated the same date as this Agreement,
among the Corporation and the Stockholders (the "Acquisition Agreement").  As a
result of the consummation of the transactions contemplated by the Acquisition
Agreement, CSI is now a wholly-owned subsidiary of the Corporation.

     Additional Stock of the Corporation has been issued in the name of the
Stockholders but is subject to earn out pursuant to the terms of the Acquisition
Agreement (the "Earn Out Stock").  In connection with the Acquisition Agreement,
the Earn Out Stock has been placed into escrow pursuant to an Escrow Agreement
dated the same date as this Agreement among the Corporation, the Stockholders
and the escrow agent named therein (the "Escrow Agreement") and will be released
to the Stockholders on the terms and conditions stated in the Acquisition
Agreement and the Escrow Agreement.  The Stockholders have voting rights to the
Earn Out Stock on the terms and conditions stated in the Acquisition Agreement
and the Escrow Agreement.

     The Stockholders are each employed by CSI pursuant to employment agreements
dated the same date as this Agreement (each, an "Employment Agreement").

     The Stockholders and the Corporation want to enter into this Agreement to
set forth their agreements regarding the antidilution, transferability and
repurchase of the Stock owned by the Stockholders under certain circumstances.

     In consideration of the mutual representations, warranties, covenants and
agreements contained in this Agreement, the parties agree as follows:
<PAGE>
 
                                 STATEMENT OF TERMS:

    1.  Restriction on Transfer of Stock.  No Stockholder may sell, pledge,
        --------------------------------                           
encumber, give, bequeath, or otherwise transfer or dispose of, or permit
to be sold, encumbered, attached or otherwise disposed of or transferred in any
manner to any person, trust, corporation or other legal entity, whether
voluntarily, involuntarily, or by operation of law, all or any portion of such
Stockholder's Stock or any rights thereto, including without limitation rights
to the Earn Out Stock, whether now owned or hereafter acquired, without first
complying with the terms of this Agreement or obtaining the prior written
consent of the Corporation.  Any attempted transfer of Stock that is not in
accordance with the terms of this Agreement will be invalid and will not be
reflected on the Corporation's books.  The Corporation and the Stockholders
acknowledge that the Stock owned by the Stockholder's has been pledged to the
Corporation pursuant to a Stock Pledge Agreement dated the same date as this
Agreement.  Upon release of the Earn Out Stock from the Escrow Agreement, it
will become Stock for all purposes of this Agreement.

     2.  Sale of Stock; Right of First Refusal.  A Stockholder who receives
         -------------------------------------                             
a solicited or unsolicited offer from another to purchase such Stockholder's
Stock or portion thereof may sell or otherwise transfer for valuable
consideration all or any portion of such Stockholder's Stock if the Stockholder
complies with this Section 2.

          (a) Notice of Proposed Sale.  A Stockholder (a "Selling Stockholder")
              -----------------------                                          
     who receives a Qualified Offer (as defined below) to buy such Stockholder's
     Stock and who wishes to sell such Stock (the "Offered Stock"), must
     promptly send a written notice to the Corporation (the "Sale Notice"), and
     will offer (or be deemed to have offered), to sell the Offered Stock to the
     Corporation at the same price and on the same terms included in the
     Qualified Offer.  The Sale Notice must include the identity of the proposed
     transferee, the terms of the transfer, and the price offered by the
     proposed transferee for the Offered Stock.  The Selling Stockholder will be
     bound to the terms of the Qualified Offer as stated in the Sale Notice and
     will keep the Corporation informed of any material changes in the proposed
     transfer.  The Selling Stockholder will also provide the Corporation with
     any other information regarding the Qualified Offer and the proposed
     transfer as reasonably requested by the Corporation.

          (b) Qualified Offer Defined.  A Qualified Offer is defined for
              -----------------------                                   
     purposes of this Agreement as a legally enforceable written offer which is
     made at arm's length from an individual or entity who is financially
     capable of carrying out the terms of the written offer.

          (c) Purchase Option.  The Corporation will have an option for 10
              ---------------                                             
     business days from the receipt of the Sale Notice to elect to purchase all,
     but not less than all, of the Offered Stock.  The Corporation may exercise
     its option by sending a written notice to the Selling Stockholder
     containing a statement that it is exercising its option pursuant to Section
     2 of this Agreement.

                                      -2-
<PAGE>
 
          (d) Purchase Price.  The purchase price of the Offered Stock will be
              --------------                                                  
     the price contained in the Qualified Offer.

          (e) Terms of Payment.  The purchase price of the Offered Stock will be
              ----------------                                                  
     paid on the same terms as the terms contained in the Qualified Offer.

          (f) Closing.  The closing of the purchase and sale contemplated by
              -------                                                       
     this Section 2 will occur at the offices of the Corporation or other
     reasonable place as the Corporation may designate no later than 10:00 a.m.
     on the 30th day following the Corporation's election to purchase all of the
     Offered Stock or the next business day.

          (g) Waiver.  If the Corporation does not exercise its option to
              ------                                                     
     purchase the Offered Stock, the Selling Stockholder may sell the Offered
     Stock to the proposed transferee at a price and on terms and conditions no
     less favorable than those set forth in the Sale Notice and in strict
     accordance with this Agreement.  The Corporation, upon request of the
     Selling Stockholder, will provide written evidence to the Selling
     Stockholder that it has waived its option, so as to permit the transfer of
     the Offered Stock.  If the Selling Stockholder fails to make the sale to
     the proposed transferee within 30 days following the Corporation's waiver
     of its option to purchase the Offered Stock, the waiver for such sale will
     lapse and any subsequent proposed transfer to the proposed transferee or
     another transferee will again be subject to the terms of this Agreement.  A
     transfer is consummated when the Corporation has been given notice that
     legal title to the shares of the Offered Stock has been transferred,
     subject to recordation on the books of the Corporation.  Any person or
     entity acquiring Stock under this Section 2 will take the Offered Stock
     free and clear of any restrictions set forth in this Agreement but subject
     to any applicable federal or state securities laws.

          (h) Unrestricted Trading Stock.  The Stockholders are not required to
              --------------------------                                       
     comply with the provisions of Sections 1 or 2 of this Agreement in order to
     effect a sale or disposition of their Stock made in compliance with
     Securities Exchange Commission Rule 144.

     3.   Termination of Employment for Cause.  If the employment of any
          -----------------------------------                           
Stockholder (the "Terminated Stockholder") is terminated for cause pursuant to
Section 3.2(b)(iii) or (iv) of the Terminated Stockholder's Employment
Agreement, the provisions of this Section 3 will apply.

          (a) Purchase Option.  The Terminated Stockholder will offer (or be
              ---------------                                               
     deemed to have offered) on the date of termination (the "Termination Date")
     to sell all of his Stock to the Corporation.  The Corporation will have an
     option for 30 days from the Termination Date to elect to purchase all or
     any part of the Terminated Stockholder's Stock.  The Corporation may
     exercise its option by sending a written notice to the Terminated
     Stockholder containing a statement that it is exercising its option
     pursuant to

                                      -3-
<PAGE>
 
     the Section 3 of this Agreement and indicating the number of shares of the
     Terminated Stockholder's Stock to be purchased.

          (b) Option Purchase Price.  The price of the Terminated Stockholder's
              ---------------------                                            
     Stock will be the Current Value Price as determined pursuant to Section 8.

          (c) Terms of Purchase.  The price of the Terminated Stockholder's
              -----------------                                            
     Stock will be paid by certified check or wire transfer in immediately
     available funds by the Corporation to the Terminated Stockholder or his
     representative.

          (d) Closing.  The closing of the purchase and sale contemplated by
              -------                                                       
     this Section 3 will occur at the offices of the Corporation or other
     reasonable place as the Corporation may designate no later than 10:00 a.m.
     on the 10th business day following the later of (i) the date on which the
     Corporation exercises its purchase option pursuant to Section 3(a) or (ii)
     the date on which the Current Value Price is finally determined.  At the
     closing, the Corporation will pay the purchase price to the Terminated
     Stockholder or his representative and the Terminated Stockholder will
     deliver to the Corporation the certificates evidencing the Terminated
     Stockholder's Stock, duly endorsed for transfer.

     4.   Other Termination of Employment or Disability of Stockholder.  If the
          ------------------------------------------------------------         
employment of any Stockholder is terminated for any reason, excluding the reason
stated in Section 3 of this Agreement and excluding the expiration of the
Terminated Stockholder's Employment Agreement by its terms, or if the
Stockholder becomes permanently disabled (as defined below), the provisions of
this Section 4 will apply.  For purposes of this Section 4, "permanent
disability" means (1) the total inability of the Stockholder to perform his
duties under the Stockholder's Employment Agreement for a period of 60
consecutive days as certified by a physician reasonably acceptable to the
Corporation and the Stockholder, or (2) the Stockholder becomes entitled to (A)
disability retirement benefits under the federal Social Security Act, or (B)
recover benefits under any long term disability plan or policy maintained by the
Corporation.  The date on which a permanent disability is determined to have
occurred is called the "Disability Determination Date."

          (a) Mandatory Offer to Sell; Purchase Option; Purchase Price.  The
              --------------------------------------------------------      
     terminated or disabled Stockholder (the "Offering Stockholder") will offer
     all of its Stock in the Corporation for sale to the Corporation at a
     purchase price to be designated by the Offering Stockholder by sending a
     written notice to the Corporation setting forth the offer price (the "Offer
     Notice"), which Offer Notice must be delivered by the Offering Stockholder
     within 60 days after (i) the Termination Date or (ii) the latter of (A) the
     Disability Determination Date or (B) the qualification of a guardian of the
     property of the disabled Stockholder (if a guardian is required), as
     applicable.  If the Offering Stockholder or the Offering Stockholder's
     guardian fails to send an Offer Notice to the Corporation within the
     relevant 60 day period, the Offering Stockholder will be deemed to have
     offered his Stock to the Corporation for the Current Value Price as
     determined pursuant to Section 8.  Upon receipt of the Offer Notice or the
     expiration of the 60 day

                                      -4-
<PAGE>
 
     period, as applicable, the Corporation will have an option for 30 days to
     elect to purchase all or any part of the Stock of the Offering Stockholder
     for the offer price stated in the Offer Notice or the Current Value Price,
     as applicable.  The Corporation may exercise its option to purchase by
     sending a written notice to the Offering Stockholder containing a statement
     that it is exercising its option pursuant to Section 4 of this Agreement
     and indicating the number of shares of Stock to be purchased and the
     applicable purchase price.  The Corporation and the Offering Stockholder or
     the Offering Stockholder's guardian, as applicable, may also negotiate a
     mutually agreeable price of the Stock during such period but, failing, such

               [THE STOCK PLEDGE AGREEMENT FOR MICHAEL S. CANNON
                    IS IDENTICAL IN ALL MATERIAL RESPECTS.]


                      STOCK PLEDGE AND SECURITY AGREEMENT


     THIS STOCK PLEDGE AND SECURITY AGREEMENT (this "Agreement"), is made on
November 6, 1996, by Michael C. Higgins, an individual resident of the State of
Maryland (the "Pledgor"), in favor of ZMAX Corporation, a Nevada corporation
(the "Corporation").

                                  BACKGROUND:

     The Pledgor owns shares of the Corporation's authorized common stock, par
value $0.001 (the "Shares").

     The Shares owned by the Pledgor were acquired as part of the acquisition of
Century Services, Inc., a Maryland corporation ("CSI") by the Corporation,
pursuant to the Stock Purchase Agreement dated the same date as this Agreement,
among the Corporation, the Pledgor and the other stockholder of CSI (the
"Acquisition Agreement").  As a result of the consummation of the transactions
contemplated by the Acquisition Agreement, CSI is now a wholly-owned subsidiary
of the Corporation.

     Additional shares of the Corporation's authorized common stock, par value
$0.001, have been issued in the name of the Pledgor but are subject to earn out
pursuant to the terms of the Acquisition Agreement (the "Earn Out Shares").  In
connection with the Acquisition Agreement, the Earn Out Shares have been placed
into escrow pursuant to an Escrow Agreement dated the same date as this
Agreement among the Corporation, the Pledgor, [name of other Pledgor] and the
escrow agent named therein (the "Escrow Agreement") and will be released from
the Escrow Agreement on the terms and conditions stated in the Acquisition
Agreement and the Escrow Agreement.

     To secure the indemnification obligations of Pledgor pursuant to Section
5.2 of the Acquisition Agreement, as the same may be modified or amended after
the date hereof (collectively, the "Obligations"), the Pledgor has agreed to
pledge and assign to the Corporation all of the Pledgor's right, title, and
interest in and to the Shares and the Earn Out Shares together with the other
collateral hereinafter described (collectively, the "Stock").

     NOW, THEREFORE, for and in consideration of the premises, the direct
benefits to be realized by the Pledgor from the Acquisition Agreement, the
mutual covenants hereinafter set forth, and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
Pledgor hereby covenants and agrees with the Corporation as follows:

                              STATEMENT OF TERMS:

     1.  Warranty.  The Pledgor warrants to the Corporation that except for the
         --------                                                              
security interest created hereby, the Pledgor owns the Stock free and clear of
all liens, charges, and encumbrances, that the Stock is duly issued, fully paid,
and non-assessable, that the Pledgor has the unencumbered and unrestricted right
to pledge the Stock, and that no consent or approval of any governmental or

Corporation a security interest in and security title to all of its right,
title, and interest in and to the Stock, and has transferred to the Corporation,
all of its right, title, and interest in and to, the Stock presently held by the
Pledgor as security for (a) all obligations of the Pledgor to the Corporation
hereunder; and (b) payment and performance of the Obligations.  The Pledgor has,
on this date, delivered the Stock to and deposited the Stock with the
Corporation, together with stock powers endorsed in blank by the Pledgor.  The
Pledgor agrees that at any time and from time to time, at the expense of the
Corporation, the Pledgor will promptly execute and deliver all further
instruments and documents, and take all further action that may be necessary, or
that the Corporation may reasonably request, in order to perfect and protect the
security interest granted hereby or to enable the Corporation to exercise and
enforce its rights and remedies hereunder with respect to all or any portion of
the Stock.  The Pledgor further agrees that if this Agreement is still in effect
at the time of the release of any Earn Out Shares from the Escrow Agreement,
such Earn Out Shares will continue to be pledged to the Corporation under the
terms of this Agreement.

     3.  Additional Shares.  In the event that, during the term of this
         -----------------                                             
Agreement:

         (a) any stock dividend, stock split, reclassification, readjustment, or
other change is declared or made in the capital structure of the Corporation,
all new, substituted, and additional shares, or other securities, issued by
reason of any such change and received by the Pledgor or to which the Pledgor
shall be entitled shall be immediately transferred to the Corporation by
delivery, together with stock powers endorsed in blank by the Pledgor, and shall
thereupon constitute Stock to be held by the Corporation under the terms of this
Agreement; and

         (b) subscriptions, warrants, or any other rights or options shall be
issued in connection with the Stock, all new stock or other securities acquired
through such subscriptions, warrants, rights, or options by the Pledgor shall be
immediately transferred by delivery to the Corporation and shall thereupon
constitute Stock to be held by the Corporation under the terms of this
Agreement.

     4.  Default.  From time to time during the term of this Agreement, upon the
         -------                                                                
occurrence of a default by Pledgor under the Acquisition Agreement which
default, if susceptible to cure, is not cured by the Pledgor to the reasonable
satisfaction of the Corporation within 60

                                      -2-
<PAGE>
 
days after the Corporation give the Pledgor notice of such default, the
Corporation may (i) transfer the Stock or such portion of the Stock based on the
Current Value Price (as defined below) necessary to satisfy the Obligations as a
result of such default, into the name of the Corporation or designate such Stock
as treasury shares, or (ii) transfer, sell, or otherwise dispose of the Stock or
such portion of the Stock based on its Current Value Price necessary to satisfy
the Obligations as a result of such default, at a public or private sale or make
other commercially reasonable disposition of the Stock or any portion thereof
after five (5) days' notice to the Pledgor.  The proceeds of the public or
private sale or other disposition, if any, shall be applied to the costs
incurred in connection with the sale, and to the Obligations, in such order as
the Corporation may determine, and any remaining proceeds shall be converted
back into Shares based on the Current Value Price which shall remain subject to
this Agreement, or if this Agreement is no longer in effect, shall be returned
to the Pledgor.  In the event the Current Value Price of any portion of the
Stock transferred into the name of the Corporation or designated as treasury
shares or the proceeds of the sale or other disposition of the Stock, if any,
are insufficient to pay such expenses, interest, principal of the Obligations,
and damages, the Pledgor shall remain liable to the Corporation for any such
deficiency.  For purposes of this Agreement, Current Value Price is (i) if the
Shares are trading, the average per share closing bid price on the Shares over
the two week period immediately preceding the date of which the default
occurred, or (ii) if the Shares are not trading, the per share value as of the
date the default occurred as such value is as determined by Arthur Andersen or
such other independent accounting firm then servicing the Corporation.

     5.  Additional Rights of Secured Party.  In addition to its rights and
         ----------------------------------                                
privileges under this Agreement, the Corporation shall have all the rights,
powers, and privileges of secured parties under the Uniform Commercial Code of
the State of Maryland and other applicable law.  All rights of the Corporation
shall be cumulative and not exclusive.

     6.  Pledgor's Obligations Absolute.  The obligations of the Pledgor under
         ------------------------------                                       
this Agreement shall be direct and immediate and not conditional or contingent
upon the pursuit of any remedies against any other person, nor against other
security or liens or encumbrances available to the Corporation or any of its
successors, assigns, or agents.

     7.  Voting Rights.
         ------------- 

         (a)  So long as a default by Pledgor has not occurred under the
Acquisition Agreement or under this Agreement, Pledgor shall be entitled to
exercise all voting rights and all other rights of the Stock.

         (b)  Upon the occurrence of a default by Pledgor under the Acquisition
Agreement or under this Agreement, and during the continuance thereof, and for
so long as any of the Obligations remain unpaid, (i) the Corporation may, upon
one (1) day prior written notice to the Pledgor of its intention to do so,
exercise all voting rights and all other rights of the Stock, but under no
circumstances is the Corporation obligated by the terms of this Agreement to
exercise

                                      -3-
<PAGE>

true and lawful attorney-in-fact and IRREVOCABLE PROXY to vote the Stock in any
manner the Corporation deems advisable for or against all matters submitted or
which may be submitted to a vote of shareholders.  The power of attorney granted
hereby is coupled with an interest and shall be irrevocable for so long as any
of the Obligations remain unpaid.

         (c)  For so long as the Pledgor shall have the right to vote the Stock,
the Pledgor covenants and agrees that it will not, without the prior written
consent of the Corporation, which consent will not be unreasonably withheld,
vote or take any consensual action with respect to the Stock which would
constitute a breach of this Agreement or a default under the Acquisition
Agreement.

     8.  Termination.  This Agreement, and the security interest hereunder
         -----------                                                      
granted to the Corporation in the Stock, shall terminate on the date that is
nine months after the date of this Agreement.  Thereafter, the Corporation shall
promptly release the Stock by delivery of the Stock to the Pledgor, unless and
except to the extent the Stock has been transferred to the name of the
Corporation, liquidated or otherwise disposed of pursuant to this Agreement.

     9.  Security Agreement.  This Agreement shall constitute a security
         ------------------                                             
agreement under the Uniform Commercial Code as in effect in the State of
Maryland.

Corporation of any power or right hereunder or of any breach or default by the
Pledgor hereunder shall be binding upon the Corporation unless in writing signed

or right hereunder or binding waiver of any default hereunder shall operate as a
waiver of any other or further exercise of such power or any other breach or
default. This Agreement, together with all documents referred to herein,

not be modified except by a writing executed by the Corporation and delivered by

adjudged to be invalid, illegal, or unenforceable by any court of competent

unenforceable shall be deemed separate, distinct, and independent, and the
remainder of this Agreement shall remain in full force and effect and shall not
be affected by such holding or adjudication.

         (c)  All representations and warranties made and given herein by the
Pledgor shall survive the execution and delivery of this Agreement and shall
remain in full force and effect until such time as this Agreement terminates as
provided in Section 8 hereof.

     Re:  Purchase and Sale of Change of Century Analysis and Conversion Tool
          ("COCACT") Software Program

Dear Mr. Higgins:

     Under a letter agreement dated as of April 30, 1997 (the "Purchase
Agreement") between Wan Hsien Information International Corporation Ltd.
("Seller") and ZMAX Corporation, a Nevada corporation ("ZMAX") with respect to
the purchase by ZMAX (or one or more controlled affiliates designated by ZMAX)
(collectively, "ZMAX") is to purchase all right, title and interest in and to
the above-referenced COCACT software program and related documentation (the
"Software").

     1.   Representations to ZMAX.  In order to induce ZMAX to consummate the
          -----------------------                                            
purchase of the Software, the undersigned jointly and severally represent and
warrant to ZMAX that (i) Seller owns all right, title and interest in the
Software, and (ii) IMS International, Inc. ("IMSI") has no present or continuing
rights in the Software and neither IMSI nor Seller have previously granted any
rights in the Software to any party other than ZMAX's affiliate Century
Services, Inc. ("CSI").

     2.   Existing License Cancellation Rights.  In connection with the purchase
          ------------------------------------                                  
of the Software under the Purchase Agreement and as a further inducement to ZMAX
to consummate such purchase, Seller, III, IMSI and Multi-Dimension International
("MDI") hereby agree that ZMAX may at any time after the closing of the
transactions contemplated by the Purchase Agreement, by written notice to MDI at
any time, terminate and cancel that certain Exclusive License grant dated April
1, 1996 between MDI (as successor to IMSI) and CSI (the "North American
License").  Upon the delivery of any such notice of termination, all obligations
of CSI under the North American License, including any obligation to pay any
license fees payable thereunder, whether due or not yet due, shall immediately
cease and terminate without further liability or obligation of any kind.
Notwithstanding the foregoing, if ZMAX cancels and rescinds the Software
purchase under the Purchase Agreement, any termination notice previously given
by ZMAX to MDI with respect to the North American License will automatically be
deemed rescinded, whereupon ZMAX's rights and obligations

Page 2

under the North American License (including ZMAX's obligation to pay any license
fees then due or to become payable thereunder) shall be deemed immediately
reinstated retroactive to the time of the termination notice as if such notice
had not been given.

     3.   Binding Provisions.  This letter reflects the parties' agreements and
          ------------------                                                   
shall be construed as a binding and enforceable agreement.

     4.   Governing Law and Venue.  This agreement shall be deemed made in and
          -----------------------                                             
shall be governed and construed in accordance with the internal laws of the
state of Maryland.  Each of the parties hereto hereby irrevocably consents to
the exclusive jurisdiction of U.S. courts in any legal or equitable action to
enforce this agreement, and (i) hereby waives sovereign immunity and irrevocably
submits itself to the jurisdiction of the appropriate federal or state court in
Maryland and (ii) to the extent permitted by applicable law, hereby waives and
agrees not to assert that any such action is brought in an inconvenient forum or
that venue of such action is improper.

     5.   Specific Performance.  Each of the parties hereto agrees that upon any
          --------------------                                                  
breach or threatened breach of this agreement irreparable injury will result to
ZMAX and money damages will be inadequate to fully remedy ZMAX's injury.
Therefore, in the event of any breach or threatened breach hereof, ZMAX shall be
entitled without posting a bond to an order of specific performance or other
equitable relief in addition to any other rights or remedies available to ZMAX
at law.

                              CONVERSION AGREEMENT

     This Conversion Agreement is dated April 28, 1997 and is entered into by
Fiserv Federal Systems, Inc., a Delaware corporation ("Fiserv"), and ZMAX
Corporation, a Nevada corporation ("ZMAX").

                             BACKGROUND STATEMENTS

     Fiserv was a joint venture partner in the Fiserv Century Services Joint
Venture, a Texas joint venture pursuant to a Joint Venture Agreement signed by
Fiserv and Century Services, Inc., a Maryland corporation ("CSI"), on April 17,
1996 (the "Joint Venture Agreement").

     Pursuant to an Assignment, Transfer and Assumption Agreement dated
September 1, 1996, between NewDominion Capital Group ("NewDominion") and Fiserv
(the "First Assignment"), Fiserv transferred all of its rights,
responsibilities, interests, obligations and liabilities in the Joint Venture,
the Joint Venture Agreement and certain related credit and security agreements
to NewDominion in exchange for, among other consideration, NewDominion's
assumption of such rights, responsibilities, interests, obligations and
liabilities and NewDominion's Promissory Note dated the same date in the
principal amount of $385,000 (the "NewDominion Note").  As required by the Joint
Venture Agreement, CSI consented to the First Assignment.

     Subsequently, pursuant to an Absolute Assignment of Contract dated
September 20, 1996, among NewDominion, Fiserv and ZMAX (the "Second
Assignment"), NewDominion transferred all of its rights, responsibilities,
interests, obligations and liabilities in the Joint Venture, the Joint Venture
Agreement and certain related credit and security agreements to ZMAX and ZMAX
assumed all of NewDominion's obligations under the First Assignment, including
the NewDominion Note.  In connection with the Second Assignment, ZMAX delivered
its promissory note dated September 19, 1996 to Fiserv in the principal amount
of $385,000 (the "ZMAX Note"), which ZMAX Note was intended to replace the
NewDominion Note.

     Fiserv and ZMAX have agreed to convert the ZMAX Note into common stock, par
value $0.001 of ZMAX ("ZMAX Stock") based on a conversion formula of the average
bid price of ZMAX Stock on March 31, 1997 less a 20% reduction.

                                   AGREEMENT

     1.  The background statements to this Agreement are incorporated into this
Agreement and are acknowledged as true and correct by the parties.

     2.  The parties acknowledge that the ZMAX Note replaced the NewDominion
Note and that the NewDominion Note is null and void and that neither ZMAX nor
NewDominion has any further obligation to pay the NewDominion Note.
<PAGE>
 
     3.  ZMAX and Fiserv acknowledge and agree that (i) the principal amount
plus accrued and unpaid interest owing under the ZMAX Note as of March 31, 1997
is $405,776, as calculated based on Exhibit A attached to this Agreement, (ii)
                                    ---------                                 
the average bid price for ZMAX Stock on March 31, 1997 was $15.8125, which
amount is the numerical average of the high bid price ($16.125) and the low bid
price ($15.5) for ZMAX Stock on that date as stated by the OTC Bulletin Board, a
service provided by the NASDAQ Stock Market, Inc., and (iii) after the 20%
reduction of such commercial average the conversion ratio for the ZMAX Note will
be based on a per share price of $12.65.

     4.  ZMAX and Fiserv agree that the ZMAX Note is hereby converted into the
right to receive 32,077 shares of ZMAX Stock (the "Conversion Stock").  Upon
execution of this Agreement, Fiserv will have no further rights under the ZMAX
Note and shall only have the right to receive the Conversion Stock as specified
in the preceding sentence.

     5.  ZMAX will promptly instruct its transfer agent to issue one certificate
for 32,077 shares of ZMAX Stock registered in the name of "Fiserv, Inc." and
deliver such certificates to Fiserv at its corporate address at 999 Summer
Street, Suite 200, Stamford, Connecticut 06905, Attention Steve L. Komar.  The
Conversion Stock to be issued to Fiserv pursuant to Paragraph 4 above will be
"restricted securities" as that term is defined in Rule 144 under the Securities
Act of 1933 and will bear an appropriate restrictive legend.

     6.  Fiserv acknowledges and agrees that its right to receive the Conversion
Stock granted by this Agreement is in complete satisfaction of the ZMAX Note.
Upon receipt of the Conversion Stock described in Paragraph 4 above, Fiserv will
mark the original ZMAX Note "Paid in Full" and original NewDominion Note
"Replaced with Promissory Note from ZMAX Corporation" and return the originals
of both notes to ZMAX at its corporate headquarters at 20251 Century Boulevard,
Germantown, Maryland 20874, Attention:  Michael C. Higgins.

     7.  ZMAX represents and warrants to Fiserv that (i) ZMAX is a corporation
duly organized, validly existing and in good standing under the laws of the
State of Nevada; (ii) ZMAX has the power and authority to issue the Conversion
Stock as contemplated by this Agreement and such issuance has been duly approved
and authorized by all necessary corporate action; (iii) the Conversion Stock,
when issued, will be duly issued, fully paid and non-assessable and issued in
compliance with all applicable laws; (iv) the execution and delivery of this
Agreement and the issuance of the Conversion Stock to Fiserv as contemplated by
this Agreement does not (a) violate ZMAX's articles of incorporation or bylaws;
(b) violate any order, statute, rule or regulation to ZMAX; or (c) conflict,
with result in a violation of, or cause a default or breach under any material
agreement applicable to ZMAX or any of its properties or assets; and (v) no
consent or approval of any third party or governmental body is necessary for the
execution and delivery of this Agreement and the issuance of the Conversion
Stock to Fiserv as contemplated by this Agreement.

     8.  Fiserv represents and warrants to ZMAX that (i) it is the holder of and
has clear title to the NewDominion Note and the ZMAX Note, free and clear of all
liens, claims, charges, security interests and other encumbrances of any kind or
nature; (ii) neither the NewDominion Note nor the ZMAX Note has been endorsed,
transferred or assigned to any party; (iii) the
<PAGE>
 
Conversion Stock is being acquired for Fiserv's own account, solely for
investment and is not being acquired with a view to or for the resale or
distribution thereof and Fiserv has no present plans to enter into any agreement
for such resale or distribution; (iv) Fiserv has substantial experience in
business or investments, including ownership of interests in new ventures and
start-up companies, and is capable of bearing the high degree of economic risks
and burdens of the investment in the Conversion Stock including the possibility
of a complete loss of all investment capital and the lack of a liquid public
market; and (v) Fiserv has had access to all information about ZMAX's corporate
records and financial and operating history and has had the opportunity to
request copies of information, ask questions and/or receive answers from ZMAX
regarding such information and all questions have been answered to its
satisfaction.

     9.  ZMAX and Fiserv agree to cooperate with each other and execute and
deliver such other instruments and documents and take such other actions as may
be reasonably requested from time to time by either party hereto as necessary to
carry out, evidence and confirm the intended purposes of this Agreement.

     10. This Agreement contains the entire agreement between the parties with
respect to the subject matter hereof and supersedes all prior arrangements and
understandings, both written and oral, expressed or implied, with respect
thereto.

     11. This Agreement will be governed by and construed in accordance with
the laws of the State of Maryland.

     12. This Agreement is binding upon and inures to the benefit of the
parties and their respective successors and assigns.

which shall be considered one and the same agreement and shall become effective
when one or more counterparts have been signed by each of the parties and
delivered to the other parties, it being understood that all parties need not
sign the same counterpart.  The parties agree that a fax signature is sufficient
to bind the parties to this Agreement.

questions have been answered to the full satisfaction of the Consultant, and the
Consultant has otherwise had the opportunity to obtain from the Company and from

officers, directors, employees, agents, and affiliates are relying on the truth
and accuracy of the representations, warranties and agreements, acknowledgements
and understandings of the Consultant to determine the applicability of such
exemptions and the suitability of the Consultant to acquire the Consultant
Shares.  The Consultant further acknowledges and agrees that it understands the
meaning and legal consequences of the representations and warranties in Section
3 herein, and hereby agrees to indemnify and hold harmless the Company and its
officers, directors, employees, agents, and affiliates from and against any and
all liability, loss, damage, cost, or expenses (including, without limitation,

representations or warranties or any failure to fulfill any covenants or
agreements contained in this Agreement.  All representations and warranties

     5.2  The Consultant agrees that it will hold the Confidential Information
in strict confidence and will not use, reproduce, disclose or otherwise
disseminate the Confidential Information for the Consultant's own benefit or for

prevent, any Confidential Information disclosed to or developed by the
Consultant to lose its character, or cease to qualify, as Confidential
Information.

     5.3  The Consultant may disclose Confidential Information as necessary to
such employees or agents (collectively, "Representatives") of Consultant (i) who
require such information in order to assist the Consultant directly in
performing the Services and only to the extent of such requirement, and (ii)

exclusivity obligations of this Agreement.  The Consultant will diligently
monitor and enforce each such Representative's compliance with the terms of this
Agreement, and, upon the request of the Company, will promptly furnish to the

responsible for any breach of this Agreement by any of the Consultant's

nature of the Confidential Information and the access to and special knowledge
of affairs and operations of the Company and its affiliates that the Consultant
and/or its Representatives will have as a result of its relationship with the
Company under this Agreement, the Consultant will not (except with the prior
written consent of the Company), during the term of this Agreement, engage,
directly or indirectly, on the Consultant's own behalf or in the service of or
on behalf of others, in any work or services similar to the Services for any
enterprise or entity engaged in the Year 2000 date conversion business.  The
Company and the Consultant hereby acknowledge and agree that the Consultant's
compliance with this provision would not prevent the Consultant from earning a
reasonable livelihood since the Consultant's experience and capabilities are
such that the Consultant is able to engage in business activities that are not
restricted by this Agreement.

     7.   Relationship of the Parties.  The Company and the Consultant
          ---------------------------

Consultant regarding information given to the Consultant by the Company that is
determined to be incorrect due to the gross negligence or willful misconduct of

have as a result of its relationship with the Company under this Agreement, the
Consultant acknowledges that great loss and irreparable harm would be suffered
by the Company if the Consultant or any of its Representatives should breach or
violate any of the covenants contained in this Agreement, and that money damages
alone would be an inadequate remedy for such loss and harm.  The parties agree
that each such covenant is reasonable and necessary to protect the interests of
the Company.  Therefore, the Company will be entitled, in addition to any other
remedies available at law or in equity, to equitable relief in the form of a
restraining order, injunction, and any other similar remedy in order to prevent
a breach or threatened breach of the provisions of this Agreement, without the
need to post a bond or other security.  The existence of any claim of the
Consultant against the Company shall not constitute a defense to the enforcement
by the Company of the covenants contained in this Agreement.

            -----------------------------

     2.1  CASH COMPENSATION.  For all services to be rendered by the Executive
          -----------------                                                   
under this Agreement, Company will pay the Executive the following amounts,
which payment will be subject to withholdings for local, state and federal
taxes, social security, and other deductions required by law or the policies of
the Company, from time to time in effect:

          (a) Base Salary.  The Company will pay the Executive an annual gross
              -----------

     beginning on or after January 1, 1998.

          (b) Bonus.  For each of fiscal year 1997, 1998, and 1999, if the
              -----                                                       
     Executive remains an employee of the Company on the last day of such fiscal
     year, Executive will be eligible to receive a bonus of 100 percent of Base
     Salary if he achieves all performance criteria established by the
     Compensation Committee of the Company.  Each bonus will be payable as soon
     as administratively feasible after the Company's audited financial
     statements for the applicable fiscal year become available.  The
     performance criteria for fiscal year 1997 have been established as follows:
     (1) if the Company attains gross revenues of at least $9 million as shown
     in the Company's audited financial statements, the Executive will receive a
     bonus of fifty percent (50%) of Base Salary, and in addition, (2) if the
     Company attains net income before interest, taxes, and amortization (EBITA)
     of $200,000 as shown in the Company's audited financial statements, the
     Executive will receive an additional bonus of fifty percent (50%) of Base
     Salary.  Such bonus for 1997 will be payable fifty percent (50%) in cash
     and fifty percent (50%) in shares of common stock, par value $.001, of the
     Company ("Common Stock").  The number of shares of Common Stock the
     Executive will receive pursuant to the bonus formula will be equal to (a)
     the dollar amount of the bonus payable in the form of shares of Common
     Stock divided by (b) the average trade price per share of Common Stock over
     the last ten trading days of the fiscal year for which the shares of Common
     Stock are granted.  In the event the Executive does not achieve the
     performance criteria, or any part thereof, for the fiscal year, the
     Compensation Committee of the Company will have the authority and
     discretion to award the bonus or any part thereof.  For fiscal years 1998
     and 1999, the Compensation Committee of the Company will, no later than 90
     days after the beginning of the fiscal year, set new performance criteria
     and establish the percentage of the bonus for such year to be paid in cash
     or shares of Common Stock and will promptly communicate the performance
     criteria and the payment percentages to the Executive, thereafter.

     2.2  BUSINESS EXPENSES.  The Executive will be entitled to be reimbursed
          -----------------                                                  
for all reasonable and necessary expenses incurred by him in connection with the
performance of his duties of employment under this Agreement in accordance with
the policies of the Company.  The Executive will, as a condition of any such
reimbursement, submit verification of the nature and amount of such expenses in
accordance with the reimbursement policies from time to time adopted by the
Company.
