                                  COMMON STOCK

    Zengine, Inc. is offering 4,290,000 shares of its common stock. As part of
this offering, we are offering 390,000 shares of our common stock at the initial
public offering price to stockholders of MCSi, Inc. (formerly known as Miami
Computer Supply Corporation) that owned at least 100 shares of common stock of
MCSi as of May 15, 2000. MCSi is our parent company and principal stockholder.
MCSi or its designees will purchase any shares of common stock that are not
purchased by MCSi stockholders under the MCSi Subscription Program. See the
section entitled "Plan of Distribution--MCSi Subscription Program."

    This is our initial public offering and no public market currently exists
for our shares. We anticipate that the initial public offering price of our
shares will be between $13.00 and $15.00 per share. We have applied to list our
common stock on the Nasdaq National Market under the symbol "ZNGN."

    MCSi is an underwriter with respect to the shares offered to the
stockholders of MCSi. MCSi is not an underwriter with respect to any other

                                 ZENGINE, INC.

    Zengine provides a comprehensive suite of technology-based solutions that
enable businesses to conduct electronic commerce. We offer a full range of
integrated services for both business-to-business, or B2B, and
business-to-consumer, or B2C, e-commerce including Web site user interface
design, product content and merchandising, personalization and customer
relationship management, advertising and sponsorship management, order
management, inventory management and order fulfillment, end-user customer
service and reporting and analysis. We provide our services as a complete, or
"turn-key," package or as component features. We believe our solution allows our
clients to achieve rapid deployment of e-commerce platforms, results in greater
economies of scale and provides cost-effective, ongoing access to leading edge
e-commerce technology. We market our services to businesses seeking to initiate,
expand or enhance their ability to conduct e-commerce. Our solutions are
delivered on an outsourced basis, which means we produce and operate our
client's e-commerce Web sites under their brand. This allows our clients to
quickly and cost-effectively create, maintain and enhance their e-commerce
presence.

    The functional components of KORE are stored on a centralized server array
which services all of our e-commerce clients. This architecture minimizes
development costs and reduces time to market because we are able to leverage
existing functionality previously developed within KORE rather than
re-engineering the functionality for each application. Upon completion, the
component or feature can be made available to other Zengine clients without
added development time or cost. In addition, the KORE Engine is built to be
highly-scalable, permitting our clients to deliver consistent quality of service
as transaction volumes increase, enabling the rapid deployment of high-speed,
dynamic e-commerce Web sites. The real-time personalization technology
proprietary to KORE allows businesses to manage online customer relationships
and personalize communication with their customers and trading partners.

    Widespread acceptance of the Internet has opened tremendous opportunities
for companies seeking growth and increased efficiencies through B2B and B2C
e-commerce. Although companies are eager to take advantage of these
opportunities, many may lack the internal resources that the analysis, design
and implementation of an effective Internet solution requires. It is often very
inefficient, expensive and time-consuming for companies to develop and staff
their own e-commerce solutions or to purchase currently available application
software packages that require sophisticated integration and maintenance. As a
result, companies increasingly seek to outsource these services. We believe our
ability to offer a full range of integrated e-commerce services demanded by
clients on a turn-key and outsourced basis provides us a competitive advantage
in today's marketplace.

    We actively market our services through a direct sales force to businesses
seeking to initiate, expand or enhance their ability to conduct e-commerce,
including:

    - original equipment manufacturers;

    - wholesalers, distributors and other businesses that create customized
      vendor and supply chain relationships over the Internet or a secure
      extranet, a computer network used to communicate business related
      information to a particular vendor, distributor or customer;

    - bricks and mortar retailers;

    - online-only retailers; and

                                       4
<PAGE>
    - Web sites that have a large and loyal user base, including portals, pure
      content sites, communities, directories and service providers.

We plan to continue to pursue these target clients and to penetrate other
markets through indirect distribution channels such as consulting firms, systems
integrators, advertising firms, and other professional services firms.

    After the commercial introduction of the Zengine service, we have
successfully launched our client's e-commerce platforms within an average of
40 days after engagement. We currently have 15 e-commerce clients. We also sell
advertising and sponsorship packages through our clients' Web sites primarily to
original equipment manufacturers whose products are featured in our client's
online stores. We have placed advertisements for 16 companies.

    Our revenue is generated through a combination of one or more of the
following: initial set-up and integration fees, subscription fees, transaction
fees and advertising and sponsorship fees through our clients' Web sites.

    We intend to grow our business by pursuing five key strategies:

    - target companies seeking to initiate, expand or enhance their ability to
      conduct e-commerce;

    - extend the capabilities of our KORE Engine;

    - leverage our client base;

    - expand our strategic alliances; and

    - assist our clients in increasing their revenues using our state-of-the-art
      e-commerce solutions.

                           OUR RELATIONSHIP WITH MCSI

    We are a subsidiary of MCSi, Inc., a systems integrator of state-of-the-art
presentation and broadcast facilities throughout the United States, Canada and
certain foreign countries. MCSi offers design-build and engineering, computer
networking and configuration services, an extensive product line and technical
support to the converging audio-visual systems, broadcast media and computer
technology industries. MCSi's common stock is traded on the Nasdaq National
Market under the symbol "MCSI." After the completion of this offering, MCSi will
own approximately 50.7% of the outstanding shares of our common stock, or
approximately 48.9% if the underwriters exercise their over-allotment option in
full.

    In addition to the MCSi Subscription Program, MCSi has advised us that it
intends to evaluate, from time to time, alternatives to maximize, for the
benefit of MCSi's stockholders, the value of its Zengine ownership. These
alternatives could include retention of all or a portion of MCSi's
shareholdings, the sale in one or more transactions of all or a portion of
MCSi's shareholdings, the distribution of MCSi's shareholdings to MCSi
shareholders possibly through a tax free spin-off under Section 355 of the
Internal Revenue Code, the issuance of debt or equity securities that enable
MCSi to monetize all or a portion of its investment in Zengine or other
transactions. We cannot assure you as to which alternative MCSi may choose, or
which may be achievable, or whether or when any such transaction will occur.

    We have entered into a number of agreements with MCSi relating to our
business. Under these agreements, MCSi will continue to provide us with certain
administrative, product fulfillment and customer support services and
facilities, and we will provide MCSi with e-commerce services for its computer
products and accessories and audio-visual products business. For more
information, please see "Risk Factors--Risks Related to Our Relationship With
MCSi" and "Certain Transactions."

Notes:

(1) The data reflects selected results of operations and balance sheet data from
    the period from our inception, which was as of January 1, 1999, through
    September 30, 1999, for the six month period ended March 31, 2000, for the
    three month period ended June 30, 2000 and for the nine month period ended
    June 30, 2000. Because our inception was on January 1, 1999, comparable data
    for the six month period ended March 31, 1999 and for the nine month period
    ended June 30, 2000 is not available. For all periods presented, revenue,
    cost of revenue and selling, general and administrative expenses include
    related party transactions with MCSi. See Note 4 to our financial statements
    included elsewhere in this prospectus.

    YOU SHOULD CAREFULLY CONSIDER THE RISKS DESCRIBED BELOW BEFORE YOU DECIDE TO
BUY OUR COMMON STOCK. IF ANY OF THE FOLLOWING RISKS ACTUALLY OCCUR, OUR
BUSINESS, FINANCIAL CONDITION OR RESULTS OF OPERATIONS WOULD LIKELY SUFFER. IN
THIS CASE, THE TRADING PRICE OF OUR COMMON STOCK COULD FALL, AND YOU MAY LOSE
ALL OR PART OF THE MONEY YOU PAID TO BUY OUR COMMON STOCK.

    THIS PROSPECTUS ALSO CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE
SUBSTANTIAL RISKS AND UNCERTAINTIES. OUR ACTUAL RESULTS, PERFORMANCE OR
ACHIEVEMENTS COULD DIFFER SUBSTANTIALLY FROM THOSE EXPRESSED IN OR IMPLIED BY

RISKS WE FACE, AS MORE FULLY DESCRIBED BELOW IN THIS SECTION AND ELSEWHERE IN
THIS PROSPECTUS.

                         RISKS RELATED TO OUR BUSINESS

<TABLE>
<S>                                       <C>
WE HAVE A LIMITED OPERATING HISTORY.      We commenced operations in January 1999 as a division of MCSi and
                                          since our incorporation in March 1999, we have operated as a
                                          subsidiary of MCSi. Our business and the services we offer are in the
                                          early stages of development. To date, 15 companies have purchased our
                                          e-commerce services and we have placed advertisements for 16
                                          companies. Accordingly, we have a very limited operating history, and
                                          our business and prospects must be considered in light of the risks
                                          and uncertainties facing early-stage companies in rapidly evolving
                                          markets such as e-commerce.

WE HAVE A HISTORY OF LOSSES, EXPECT       We are not profitable and may not generate sufficient revenue to ever
FUTURE LOSSES AND MAY NOT ACHIEVE         become profitable. To the extent such losses continue, our accumulated
PROFITABILITY.                            deficit will increase and our stockholders' equity will decrease. We
                                          incurred net losses of $934,000 for the period from inception, which
                                          was as of January 1, 1999, to September 30, 1999, and net losses of
                                          $76,000 for the nine months ended June 30, 2000. We anticipate that we
                                          will substantially increase our marketing, technology and
                                          infrastructure, software development and general and administrative
                                          expenses in fiscal 2000 and, as a result, we expect to incur
                                          additional losses for the foreseeable future. In addition, our limited
                                          operating history makes prediction of future results difficult and,
                                          accordingly, we may not achieve or sustain profitability.

THE EXPECTED FLUCTUATIONS OF OUR          As a result of our limited operating history, we do not have
QUARTERLY RESULTS COULD CAUSE OUR STOCK   meaningful historical financial data for quarterly periods on which to
PRICE TO FLUCTUATE OR DECLINE.            base planned operations. Our expense levels are based in part on our
                                          personnel and software development requirements as well as our
                                          expectations as to future revenues. We anticipate that our operating
                                          expenses will increase substantially for the foreseeable future as we
                                          continue to extend the capabilities of our KORE Engine, increase our
                                          sales and marketing activities and broaden our customer support
                                          capabilities.

                                          We expect to experience significant fluctuations in future quarterly
                                          operating results. These fluctuations may be caused by many factors
                                          including, among others:

                                          - cancellation of orders prior to full deployment;

                                          - nonrenewal of service agreements;

                                          - changes in our business strategy; and

                                          - changes in key personnel.

                                          We anticipate that, for the foreseeable future, a significant portion
                                          of our revenues will be derived from a limited number of clients,
                                          including MCSi, and the timing of receipt and fulfillment of any such
                                          orders is expected to cause material fluctuations in our operating
                                          results, particularly on a quarterly basis. In addition, in the near
                                          term, we intend to increase significantly our personnel, including our
                                          software engineers, direct sales and marketing personnel. The timing
                                          of such expansion and the rate at which new engineers and sales people
                                          become productive could also cause material fluctuations in our
                                          quarterly operating results.

                                          Due to the foregoing factors, quarterly revenues and operating results
                                          are difficult to forecast, and we believe that period-to-period
                                          comparisons of our operating results will not necessarily be
                                          meaningful and should not be relied upon as any indication of future
                                          performance. It is likely that our future quarterly operating results
                                          from time to time will not meet the expectations of market analysts or
                                          investors, which may have an adverse effect on the price of our common

OUR LENGTHY SALES CYCLE MAY CAUSE         The sales cycle for our services is long, typically ranging two months

                                          decision by our clients regarding their information systems
                                          infrastructure. Accordingly, the decision to purchase our services
                                          typically requires significant pre-purchase evaluation. We spend
                                          substantial time educating and providing information to prospective
                                          clients regarding the use and benefits of our services. During this
                                          evaluation period, we may expend substantial funds in sales, marketing
                                          and management efforts. This lengthy sales cycle may cause operating
                                          results to vary significantly from period to period.

                                          services require that we launch a clients' Web site, we will not
                                          recognize any revenue until we have launched our client's e-commerce
                                          Web site. If we experience delays in the progress on a previously
                                          announced project or in the satisfaction of contract terms required
                                          for revenue recognition in a particular quarter, we may not be able to
                                          recognize revenue until a later period, causing our quarterly results
                                          to fluctuate. This could cause our stock price to decline.

A LOSS OF A MAJOR CLIENT COULD CAUSE A    We currently have 15 e-commerce clients and 16 advertising and

                                          continue to account for a substantial portion of our revenue for the
                                          foreseeable future. As a result, if we lose a major client or if a
                                          contract is delayed, canceled or deferred, our revenue and operating
                                          results would be adversely affected.

                                          dedicate significant resources to a client whose business does not
                                          generate substantial transactions or whose products do not generate
                                          substantial customer sales, our business may suffer.

OUR CURRENT REVENUE DEPENDS ON            We currently expect that advertising and sponsorship fees will account

                                          year. The arrangements under which we receive these fees typically are
                                          of a limited duration. Accordingly, our revenue from advertising and
                                          sponsorship fees may not be sustained over the longer term.

PERSONALIZATION MAY NOT BE SUCCESSFUL IN  The centerpiece of our service offering to our clients is the high

CLIENTS.                                  sales proposition to our clients is that the personalization of the

                                          increased purchase size and greater customer loyalty. If our sales

                                          clients, we could lose that business, and possibly future business,
                                          which would result in a material adverse effect on our results of
                                          operations.

LOSS OF KEY EMPLOYEES COULD HURT OUR      We believe our future success will depend upon our ability to retain

                                          opportunities and challenges of our business. Each of these executives
                                          is subject to a three year employment agreement which is terminable at

                                          We expect to add additional key personnel in the near future,
                                          including software engineers and direct sales and marketing personnel.
                                          During the next twelve months, we anticipate that our employee related
                                          costs will increase approximately $4.5 million over current levels.
                                          Our future success and our ability to expand our operations will also
                                          depend in large part on our ability to attract and retain additional

                                          personnel. Competition for these types of employees is intense due to
                                          the limited number of qualified professionals, particularly in the San

SERVICES.                                 utilize a third party payment processor for a portion of the
                                          transactions we handle. Both the third party processor and we rely on
                                          public key cryptography. This is an encryption method that utilizes
                                          two keys, a public and a private key, for encoding and decoding data,
                                          and digital certificate technology, or identity verification, to
                                          provide the security and authentication necessary for secure
                                          transmission of confidential information. Regulatory and export
                                          restrictions may prohibit us from using the strongest and most secure
                                          cryptographic protection available and thereby expose us to a risk of
                                          data interception. A party who is able to circumvent our security
                                          measures could misappropriate proprietary information or interrupt our
                                          operations. Any compromise or elimination of our security could harm
                                          our reputation and reduce demand for our services. We currently carry
                                          no insurance to specifically protect us against this risk.

THE INTENSE COMPETITION IN OUR INDUSTRY   The market for our services is intensely competitive and subject to

OUR SERVICES.                             future. Our primary source of competition comes from e- commerce
                                          retailers who develop their own custom systems or engage consultants
                                          who install packaged software systems. Online retailers who have made
                                          large investments to develop custom systems may be less likely to
                                          adopt an outsourced transaction processing strategy. We also face
                                          competition from companies such as Art Technology Group, Breakaway
                                          Solutions, Broadvision, E.piphany, Net Perceptions and
                                          USinternetworking. In addition, other companies may enter the market
                                          for our services. In the future, we may also compete with large
                                          companies that derive a significant portion of their revenues from
                                          e-commerce and may offer, or provide a means for others to offer,

                                          our shares in the public market could be adversely affected because of
                                          the reduced liquidity and the uncertainty as to if, when and how the
                                          shares held by MCSi would be sold or distributed to the public. Until
                                          a decision is made by MCSi, we cannot predict what will occur, what
                                          effects will result from such decision, or whether or when we or our
                                          shareholders will obtain the expected benefits, if any.

WE DEPEND ON MCSi FOR VARIOUS SERVICES    We have historically been dependent on MCSi for various services,
AND FOR A SIGNIFICANT PORTION OF OUR      including product fulfillment and distribution, customer service,
REVENUE.                                  facilities, human resources, management information systems, as well
                                          as for working capital. We have entered into a distribution services
                                          agreement, sublease agreement and an administrative services agreement
                                          with MCSi under which MCSi will continue to provide these services to
                                          us until October 2001 and lease property and equipment to us through
                                          May 2001. When the term of these agreements expire, we will need
                                          either to extend the term, engage other entities to perform these
                                          services or perform these services ourselves. MCSi may not continue to
                                          provide these services after the initial term of these agreements and
                                          the cost of these services could be significantly higher if we
                                          purchase services from other parties or devote resources to handle
                                          these functions internally.

                                          In addition, we provide e-commerce services for MCSi's computer supply
                                          and audio-visual products business under a two-year agreement. As a
                                          result, MCSi is one of our largest clients, and we currently expect
                                          that MCSi will remain a significant client for the foreseeable future.
                                          Consequently, a substantial portion of our business will be dependent
                                          upon the success of MCSi's sales and

                                          marketing of its products. Any decline in sales experienced by MCSi
                                          will have a negative effect on the revenues we would obtain from this
                                          agreement. Revenues related to the e-commerce services agreement with
                                          MCSi represented $2,408,121, or 47.2% of our total revenues for the
                                          nine months ended June 30, 2000. Additionally, for the nine months
                                          ended June 30, 2000, we had advertising revenue of $2,336,750, or
                                          45.8% of total revenue, which was primarily derived from original
                                          equipment manufacturer product advertisers who either placed banner
                                          advertisements on clients' Web pages which we serve or purchased
                                          preferential placement of the OEM products on clients' Web stores.
                                          MCSi has supply arrangements with the OEM companies that purchase
                                          advertising from us. Although we negotiate each OEM advertising
                                          arrangement, it is possible that MCSi's relationship with the OEM
                                          companies influenced our obtaining the advertising and we may not have
                                          obtained the advertising without MCSi's relationship. If our
                                          relationship with MCSi were to change adversely, we could lose this
                                          business.

                                          All of our agreements with MCSi were made in the context of a
                                          parent-subsidiary relationship. The prices charged to us, or by us, or
                                          the overall terms and conditions under these agreements may be higher
                                          or lower than the prices that may be charged by, or to, unaffiliated
                                          third parties for similar services.

                                          by MCSi, MCSi could require us to agree to an amendment to the

                                          sublease agreement or any other agreement that may be more or less

                                          could occur. In addition, the sale of these shares could impair our
                                          ability to raise capital through the sale of additional equity
                                          securities. Upon completion of this offering, 12,183,480 shares of
                                          common stock will be held by existing stockholders. As a result of
                                          contractual restrictions in our agreement with William Blair & Co.,
                                          MCSi, our officers and directors and our investors will be prohibited
                                          from selling their shares of common stock prior to 180 days after this
                                          offering. We have agreed to register all of the shares of our common
                                          stock to be held by MCSi and these investors and executive officers
                                          upon demand after this offering. It is possible that a substantial
                                          amount of our common stock could be sold in the open market after the
                                          "lock-up" period in anticipation of, or following, any distribution of
                                          our shares by MCSi, the investors, the director or executive officers.
                                          If that occurs, it could cause the price of our common stock to
                                          decrease. See "Shares Eligible for Future Sale."

                                          liabilities divided by the total number of shares of common stock
                                          outstanding prior to this offering. Accordingly, purchasers of common

                                USE OF PROCEEDS

    We estimate that we will receive net proceeds of $55.0 million from the sale
of the 4,290,000 shares of common stock in this offering, at the assumed initial
public offering price of $14.00 per share and after deducting estimated
underwriting discount and the estimated offering expenses of $1.2 million. If
the underwriters' over-allotment option is exercised in full, we estimate that
our net proceeds will be $62.7 million.

    The principal purposes of this offering are to obtain additional working
capital, create a public market for our common stock and to facilitate future
access by Zengine to public equity markets. We generally intend to use the net
proceeds of this offering as follows:

    - hiring of additional technical, direct sales and marketing personnel
      (approximately $9 million);

    - expansion of our market activities (approximately $12 million);

    - capital expenditures (approximately $5 million); and

    - working capital (approximately $29 million).

    In addition, we may, if appropriate opportunities arise, use an undetermined
portion of the net proceeds to engage in strategic alliances or to acquire or
invest in complementary companies, product or service lines, or technologies.
While we engage in discussions relating to strategic alliances or potential
investments which complement our existing business on an on-going basis, we do
not have any agreements or commitments with respect to any proposed alliance,
acquisition or investment. Pending such uses, we will invest the net proceeds in
investment grade, interest-bearing securities.

                                DIVIDEND POLICY

    We have never paid any cash dividends on our common stock and do not
anticipate paying any cash dividends in the foreseeable future.

                                    DILUTION

    The net tangible book value of our common stock as of June 30, 2000 was
$4.3 million, or $0.35 per share of common stock. Net tangible book value per
share represents the amount of our total tangible assets less our total
liabilities, divided by the total number of shares of common stock outstanding
prior to this offering.

    After giving effect to this offering and the receipt of $55.0 million of net
proceeds from this offering, based on an assumed initial public offering price
of $14.00 per share, the pro forma net tangible book value of the common stock
as of June 30, 2000 would have been approximately $59.3 million, or $3.60 per
share. This amount represents an immediate increase in net tangible book value
of $3.25 per share to MCSi and our other existing stockholders, and an immediate
dilution in net tangible book value of $10.40 per share to purchasers of common
stock in this offering. Dilution is determined by subtracting pro forma net
tangible book value per share after this offering from the amount of cash paid
by a new investor for a share of common stock. The following table illustrates
such dilution:

</TABLE>

    If the underwriters' over-allotment option is exercised in full, sales in
this offering will reduce the number of shares of common stock held by the
existing stockholders to approximately 71.4% of the total shares of common stock
outstanding after the offering and will increase the number of shares held by
new investors to 4,875,000 or approximately 28.6% of the total shares of common
stock outstanding after the offering.

    The foregoing table excludes outstanding stock options to purchase an
aggregate of 1,380,118 shares of common stock at a weighted average exercise
price of $.89 per share and an outstanding warrant to purchase up to 1.7% of the
shares of common stock outstanding immediately after this offering, not
including the underwriters' overallotment option, at the initial public offering
price per share. Exercise of these outstanding options and the warrant would
result in dilution per share of $.05 after the offering. We may also issue
additional shares of common stock upon exercise of future stock option grants,
which could also result in additional dilution to then-existing stockholders.

Notes:

(1) The data reflects selected results of operations and balance sheet data from
    the period from our inception, which was as of January 1, 1999, through
    September 30, 1999 and for the nine month period ended June 30, 2000.
    Because our inception was on January 1, 1999, comparable data for the six
    month period ended March 31, 1999 and for the nine month period ended
    June 30, 2000 is not available. For all periods presented, revenue, cost of
    revenue and selling, general and administrative expenses include related
    party transactions with MCSi. See Note 4 to our financial statements
    included elsewhere in this prospectus.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

    THE FOLLOWING DISCUSSION SHOULD BE READ IN CONJUNCTION WITH "SELECTED
FINANCIAL DATA" AND THE FINANCIAL STATEMENTS AND THE ACCOMPANYING NOTES THERETO
INCLUDED ELSEWHERE IN THIS PROSPECTUS. THE FOLLOWING INFORMATION CONTAINS
FORWARD-LOOKING STATEMENTS THAT INVOLVE CERTAIN RISKS AND UNCERTAINTIES. ACTUAL
RESULTS AND EVENTS MAY DIFFER SIGNIFICANTLY FROM THOSE DISCUSSED IN THE
FORWARD-LOOKING STATEMENTS.

OVERVIEW

    We were formed as a division of MCSi in January 1999 to sell computer and
audio-visual products, primarily to the small office/home office, or SOHO,
market. We were subsequently incorporated as a wholly owned subsidiary of MCSi
in March 1999. Also in March 1999, we hired three key executives, Mr. Joseph
Savarino, Mr. Lalit Dhadphale and Mr. Christopher Feaver, to revise our business
concept beyond the sale of computer and audio-visual products to the Zengine
business model of providing a full range of e-commerce services to the B2B and
B2C markets. At such time, we also began to work with dedicated Web sites of
MCSi to enhance, modify and maintain these Web sites; we subsequently entered
into an e-commerce agreement with MCSi related to these activities on
October 1, 1999. We entered into our first third party client contract using the
Zengine business model in September 1999, and we legally changed our corporate
name to Zengine, Inc. in the Fall of 1999, after doing business as Zengine since
March 1999.

ZENGINE SERVICES

    We provide a comprehensive suite of technology-based solutions that enable
businesses to conduct electronic commerce. We offer a full range of integrated
services for both B2B and B2C e-commerce platforms, including Web site user
interface design, product content and merchandising, personalization and
customer relationship management, advertising and sponsorship management, order
management, inventory management and order fulfillment, end-user customer
service and reporting and analysis. Our solutions are delivered on an outsourced
basis, which means we produce and operate our client's e-commerce Web sites
under their brand. This allows our clients to quickly and cost-effectively
create, maintain and enhance their e-commerce presence. Our proprietary
technology and infrastructure, the KORE Engine, enables these services; KORE is
a highly scalable and reliable platform that uses personalization as the
centerpiece for managing on-line customer relationships.

    In performing our services under the Zengine business model, we enter into
contractual arrangements with our clients that describe the services we will
perform. We generate revenues through service fees, which include integration
and set-up, monthly subscription and transaction fees and from advertising and
sponsorships on Web pages we service on our client's stores.

REVENUE

    SERVICE FEES

    INTEGRATION AND SET-UP FEES

    We provide integration and set-up services to our clients. Under these
arrangements, our services may include the development or design of a client's
Web site, migration of the client's current Web site content to our technology,
integration of the client's Web site to the client's current computer systems or
other similar activities. To the extent that these fees are associated with a
contract to provide subsequent outsourced transaction-based services to a
client, these fees are recognized ratably over the term of the transaction
services agreement. Otherwise, revenue is recognized when the service is
completed, the client has accepted the service and we have no future obligation
to provide any additional services.

                                       24
<PAGE>
    SUBSCRIPTION FEES

    Our subscription arrangements provide for maintenance and related services
over a specified time for a fee. Revenue from subscription fees is recognized
ratably over the term of the subscription.

    TRANSACTION FEES

    We provide outsourced transaction-based services to customers, such as
providing product content and merchandising, transaction processing, order
management, custom fulfillment and end-user customer service. Revenues from
transaction fees are generally in the form of a commission. Under our first two
arrangements with third party clients, our revenue is determined as a percentage
of the gross margin on revenues. Under all other arrangements entered into
between our clients and us, our revenue is based on a percentage of net
revenues. Revenue from transaction fees is recognized when the service is
completed.

    ADVERTISING AND SPONSORSHIP FEES

    Revenues from advertising take the form of fees when we sell banner
advertising, product placement or other forms of advertising on Web pages we
service on our clients' stores. These arrangements call for continuous
advertising or product placement over a certain time period and are not
contingent upon events such as obtaining certain levels of sales, Web site
visits or other factors. Revenue is recognized ratably over the period of the
advertising/product placement services based on the fulfillment of obligations
under the advertising/product placement arrangements.

EXPENSES

    Our expenses consist of costs associated with our revenues and selling,
general and administrative expenses. Cost of revenues consists of the salaries,
employee benefits and related expenses of our people who work on preparation of
our client's sites. It also includes the depreciation of the computer hardware
and software utilized in providing these services. Furthermore, we have entered
into a distribution services agreement with MCSi where we pay MCSi three percent
of the total revenues we receive from our third party clients on the
transactions in which MCSi performs the inventory management and/or order
fulfillment functions. Our selling, general and administrative expenses includes
the salaries, employee benefits, travel and related expenses of our sales
personnel, advertising expenses and marketing and sales support functions, as
well as our facility related expenses.

    We anticipate that our expenses will increase substantially in the future as
we expand our services to new clients.

ARRANGEMENTS WITH MCSI

    At the time that MCSi began our operations, MCSi had been providing
dedicated Web site order fulfillment services to a variety of its business
customers (the "dedicated Web site operations"). Over the course of the Spring
and Fall of 1999, MCSi began to transfer its dedicated Web site customers to us
for designing, enhancing and providing certain support services to these sites.
Effective October 1, 1999, we entered into an e-commerce services agreement with
MCSi whereby we provide design, enhancement and certain support services to the
dedicated Web site operations of MCSi and receive a fee of ten percent on the
retail value of goods sold to these dedicated Web site customers.

    Also effective October 1, 1999, we entered into a distribution services
agreement with MCSi, under which we will pay MCSi three percent of the retail
value of goods sold to third party clients who utilize the inventory management
and order fulfillment services which MCSi provides to us. We subsequently
amended the agreement to pay MCSi for warehouse space equal to a percentage of
MCSi's gross expenses relating to the operation of the warehouse for us through
the end of the term of the agreement. Finally, effective October 1, 1999, we
entered into an administrative services agreement,

                                       25
<PAGE>
under which MCSi provides us with accounting, treasury, tax, insurance and other
services for an annual fee of $720,000 per year, and a sublease and equipment
lease agreement under which MCSi leases to us real and personal property used in
our business for an annual fee of $150,000 per year.

    The terms of our arrangements with MCSi do not necessarily represent those
which would be obtained in an arm's-length transaction with an unrelated party.
Therefore, the transactions might have been on less favorable terms than would
have been obtained from an unaffiliated third party.

RESULTS OF OPERATIONS

    During September 1999, we signed our first client contract under the Zengine
business model, and we began earning revenue from this contract in
October 1999. Accordingly, our financial results prior to October 1, 1999 are
not representative of our current business model. We have not presented amounts
for the six month period ended March 31, 1999 or the nine month period ended
June 30, 1999 as we were not in existence for that period and were not operating
under our current business model. Accordingly, prior period amounts from our
inception (January 1, 1999) to June 30, 1999 are not meaningful or comparable.

REVENUE

    Revenue for the periods presented is summarized as follows:

</TABLE>

    The increases in revenues, as shown above, reflect the implementation of our
business plan and the launch of our clients' e-commerce Web sites, along with
adding additional Web sites being serviced under our e-commerce services
agreement with MCSi.

    Our revenue for the nine months ended June 30, 2000 totaled $5,104,286. At
June 30, 2000, we had 12 e-commerce clients. Service fee revenue from the MCSi
dedicated Web sites was $2,408,121 for the nine months ended June 30, 2000,
which was 47.2% of our total revenue for the period. Our current arrangement to
service the MCSi dedicated Web sites expires on October 1, 2001. In addition, we
had advertising revenue of $2,336,750, or 45.8% of total revenue, which was
primarily derived from OEM product advertisers who either placed banner
advertisements on clients' Web pages which we serve, or purchased preferential
placement of the OEM manufacturers products on clients' stores. We have provided
advertising or sponsorship services to 14 clients as of June 30, 2000. MCSi has
supply arrangements with the OEM companies that purchase advertising from us.
Although we negotiate each OEM advertising arrangement, MCSi's relationship with
the OEM companies could have influenced our obtaining the advertising and we may
not have obtained the advertising without MCSi's relationship.

    Our revenue for the three months ended June 30, 2000 totaled $2,393,370.
Service fee revenue from the MCSi dedicated Web sites was $1,098,293 for the
three months ended June 30, 2000, which was 45.9% of our total revenue for the
period. In addition, we had advertising revenue of $987,500 or 41.3% of total
revenue, which was primarily derived from OEM product advertisers who either
placed banner advertisements on clients' Web pages which we serve, or purchased
preferential placement of the OEM manufacturers products on clients' stores.

                                       26
<PAGE>
    Our revenue for the six months ended March 31, 2000 totaled $2,710,916.
During the six months ended March 31, 2000, we initiated our Zengine service
offerings and began servicing e-commerce clients. At March 31, 2000 we had seven
e-commerce clients. Service fee revenue from the MCSi dedicated Web sites was
$1,309,828 for the six months ended March 31, 2000, which was 48.3% of our total
revenue for the period. In addition, we had advertising revenue of $1,349,250,
or 49.8% of total revenue, which was primarily derived from OEM product
advertisers who either placed banner advertisements on clients' Web pages which
we serve, or purchased preferential placement of the OEM manufacturers products
on clients' stores.

    From the date of our inception to September 30, 1999, our revenues totaled
$4,089. These revenues arose from the sale of computer supply and audio-visual
products to consumers under our previous business model.

COST OF REVENUE

    Our cost of revenue includes the amortization of capitalized computer
software costs, the costs of our employees to perform integration and other
services and the three percent fee we pay to MCSi under the distribution
services agreement, which expires on October 1, 2001.

    As a percentage of our revenues, our gross margin was 88.2% for the nine
months ended June 30, 2000, 88.7% for the three months ended June 30, 2000, and
87.7% for the six months ended March 31, 2000, all under our current business
model. These percentages fluctuate depending primarily on the timing as to when
we add additional employees to perform integration and other services.

    Our costs of revenues were $23,511 for the period ended September 30, 1999
and reflects costs we incurred for the products we sold arising from the
activities of our previous business model and the amortization of capitalized
computer software costs.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

    Selling, general and administrative expenses for the periods presented,
along with these amounts stated as a percentage of our revenues during the
periods we operated under the Zengine business model, is shown below:

<TABLE>
<S>                                                        <C>          <C>
Nine months ended June 30, 2000..........................  $4,700,646     92.1%
Three months ended June 30, 2000.........................  $2,413,801    100.9%
Six months ended March 31, 2000..........................  $2,286,845     84.4%
</TABLE>

    Changes in selling, general and administrative expenses are also influenced
as to the timing of when we add additional personnel to support these functions.
Our selling, general and administrative costs during the nine months and three
months ended June 30, 2000 was also impacted by an amendment to our distribution
services agreement with MCSi which totalled $326,751.

    Our selling, general and administrative expenses for the nine months ended
September 30, 1999 were $914,201 and relate primarily to costs incurred to
develop the Zengine business model. The more significant selling, general and
administrative expenses relate to payroll and accounting processing costs,
salaries and rent.

INCOME TAXES

    We did not provide for any income taxes because we have prepared our
provision for income taxes as if we were a separate entity. We do not owe any
income taxes because we have incurred tax basis operating losses since our
inception, and we did not record any deferred tax benefits relating to these
operating losses or any other deferred tax benefits because we presently believe
it is more likely than not that they will not be realized.

LIQUIDITY AND CAPITAL RESOURCES

    During the nine months ended June 30, 2000, we used $1,667,492 of cash in
operations primarily as a result of our loss from operations, increased
receivables and increased other assets relating to deferred offering costs and
prepayments to a customer for sole provider status. We used $2,203,963 of cash
for investing activities to fund a demand note to MCSi and to fund expenditures
for software development and capital expenditures. Cash provided by financing
activities of $3,871,049 is the net cash we received from the sale of our common
stock during the period.

    During the three months ended June 30, 2000, we used $414,963 of cash in
operations primarily as a result of our loss from operations and increased
receivables. We generated $364,230 of cash from investing activities as a result
of favorable net cash settlements with MCSi relating to our demand note with
MCSi, partially offset by the funding of software development and capital
expenditures.

    During the six months ended March 31, 2000, we used $1,252,529 in cash flow
from operations, primarily as a result of increased receivables and prepayments
to a customer for sole provider status, offset by increased accruals. We used
$2,568,193 of cash for investing activities to fund a demand note to MCSi and to
fund expenditures for software development costs and capital expenditures. Cash
provided by financing activities of $3,871,049 is the net cash we received from
the sale of our common stock during the period.

    Primarily by virtue of our losses from operations, we used $730,076 in cash
for operations for the period from inception to September 30, 1999.
Additionally, we used cash of $376,405 for investing purposes, primarily
reflecting software development costs incurred to develop our technology, once
we had established its technological feasibility. We were provided cash flow
from financing activities of $1,106,887 for the period from inception to
September 30, 1999 because MCSi paid for and contributed to our capital the cash
we required to fund our operating and investing activities.

GENERAL

    Since our inception, we have looked to MCSi to provide the financial and
capital resources we have required to carry on our business activities. Should
the offering of the common stock to which this prospectus relates not occur, we
would continue to look to MCSi for the financial resources we need to carry on
our operations, and we believe those resources will be adequate to fund our
operations for the next twelve months.

    If this offering of common stock occurs, MCSi will not be permitted to loan
us money to provide funding for our operations, and if the proceeds from the
offering are not sufficient to fund our future operating and investing needs, we
may have to look to other sources of financing such as bank loans or the
issuance of debt or equity securities. In any event, we believe that the capital
resources provided by this initial public offering will be sufficient to enable
us to pursue our operations under our business model for the foreseeable future.

    As described above, we have entered into certain arrangements with MCSi.
Each of these arrangements provide for monthly "net" settlement, which typically
is effectuated by increasing or decreasing the amounts receivable/payable
between MCSi and us.

    On October 1, 1999, we entered into an e-commerce services agreement with
one of our clients, Excite@Home. In addition to our providing e-commerce
services, we entered into a stock purchase agreement which called for
Excite@Home and an unrelated financial investor, Wilblairco Associates (an
affiliate of our managing underwriter, William Blair & Company) to purchase an
aggregate of 1,804,956 shares of our common stock for $2.22 per share, or
$4,000,000. After deducting expenses related to the sale of common stock, we
realized net proceeds of $3,871,049. We loaned these net proceeds to MCSi under
a demand note arrangement and we use these funds as needed to fund our
operations. The e-commerce services agreement also commits us to pay $600,000 to
be the sole audio-visual provider of Excite@Home and Dow Jones & Co.'s Work.com
Web site and to purchase

                                       28
<PAGE>
$3,400,000 of advertising from Excite@Home through December 2001, which we will
expense as the related advertising services are provided. See "Certain
Transactions."

    In March 2000, Zengine and PNC Bank agreed to enter into a secured
expandable revolving line of credit to provide Zengine up to $5,000,000 for
working capital and general corporate purposes. The line of credit will have a
term of one year and is subject to the successful completion of an initial
public offering with proceeds of at least $35 million.

    As a result of entering into the lease and administrative services
agreements with MCSi, the Company is committed to the following payments for the
periods presented below:

RECENT ACCOUNTING PRONOUNCEMENTS

    We are not aware of any pending accounting pronouncements that we believe
will have a material impact on our financial position, results of operations or
cash flows, including the provisions of Staff Accounting Bulletin 101, which was
recently issued by the Securities and Exchange Commission.

MARKET RELATED RISKS

    Currently, all of our operations are domestic, we have no debt and we do not
hold or issue derivative financial instruments. Accordingly, our risk relating
to foreign exchange and changes in interest rates has not been an issue. In the
future, we intend to pursue international clients and will enter into a
revolving line of credit that has a variable rate of interest. Accordingly, we
will need to develop means to monitor and control these market related risks in
the future.

SEASONALITY

    We anticipate that we will experience some seasonality based on the year end
holiday selling season.

                                    BUSINESS

OVERVIEW

    Zengine provides a comprehensive suite of technology-based solutions that
enable businesses to conduct electronic commerce. We offer a full range of
integrated services for both business-to-business, or B2B, and
business-to-consumer, or B2C, e-commerce including Web site user interface
design, product content and merchandising, personalization and customer
relationship management, advertising and sponsorship management, order
management, inventory management and order fulfillment, end-user customer
service and reporting and analysis. We offer a comprehensive set of services and
focus on personalized customer relationships. We provide our solutions on a
complete, or "turn-key," package basis or as component features and are able to
significantly reduce our clients' time-to-market and the infrastructure, human
resource, development and maintenance costs typically required for enterprise
wide e-commerce initiatives. We market our services to businesses seeking to
initiate, expand or enhance their ability to conduct e-commerce. Our solutions
are delivered on an outsourced basis, which means we produce and operate our
client's e-commerce Web sites under their brand. This allows our clients to
quickly and cost-effectively create, maintain and enhance their e-commerce
presence.

    Zengine's solutions are centered around its proprietary technology and
infrastructure, the KORE Engine. The functional components of KORE are stored on
a centralized server array which services all of Zengine's clients. This
architecture minimizes development costs and reduces time to market because we
are able to leverage existing functionality previously developed within KORE
rather than re-engineering the functionality for each application. Upon
completion, the component or feature can be made available to other Zengine
clients without added development time or cost. In addition, the KORE Engine is
built to be highly-scalable, permitting our clients to deliver consistent
quality of service as transaction volumes increase, enabling the rapid
deployment of high-speed, dynamic e-commerce Web sites. The real time
personalization technology proprietary to KORE allows businesses to manage
online customer relationships and personalize communication with their customers
and trading partners. The KORE Engine gives us the ability to offer both
front-end Web site content and design along with back-end transaction processing
and order management functionality. We believe that this allows our clients to
achieve rapid deployment of e-commerce platforms, results in greater economies
of scale and provides cost-effective, ongoing access to leading edge e-commerce
technology. The KORE Engine enables the creation of an e-commerce platform that
creates or replicates the look, feel and functionality of the client's Web site.

    Using our technology and services, our client's customers experience all
services under our client's brand, including browsing, ordering, paying,
receiving ordered products and obtaining customer support by e-mail or
telephone. When visitors enter a client's home page, secure extranet or store
function within a client's Web site, they are seamlessly and transparently
transferred to our network where they enter a personalized shopping environment.
By soliciting and tracking user information and behavior, we use our KORE Engine
to anticipate user preferences and interests and assist visitors in obtaining
desired products. We solicit user information by means of questionnaires,
warranty cards, rebates and surveys and we track user behavior through purchase
history and Web site visitation behavior. Accordingly, we can suggest products
to a user based upon their prior transactions and preferences. Our B2B services
focus on building secure corporate extranets for clients who sell products
directly to their corporate customers and channel partners as well as clients
who are purchasing operating resources from their vendors. To date, we have
provided our clients a fully operational Web site to transact e-commerce
business within an average of 40 days from the commencement of our services.

    We actively market our services through a direct sales force to businesses
seeking to initiate, expand or enhance their ability to conduct e-commerce,
including:

    - original equipment manufacturers;

    - wholesalers, distributors and other businesses that create customized
      vendor and supply chain relationships over the Internet or a secure
      extranet;

                                       30
<PAGE>
    - bricks and mortar, or BAM, retailers;

    - online-only retailers; and

    - Web sites that have a large and loyal user base, including portals, pure
      content sites, communities, directories and service providers.

    Our plan is to continue to pursue these target clients and to penetrate
other markets through indirect distribution channels such as consulting firms,
systems integrators, advertising firms, and other professional services firms.

    Our revenue is generated through a combination of one or more of the
following: initial set-up and integration fees, subscription fees, transaction
fees and advertising and sponsorship fees.

INDUSTRY BACKGROUND

    THE INTERNET

    Widespread acceptance of the Internet has opened numerous opportunities for
companies seeking growth and increased efficiencies through B2B and B2C
e-commerce. The GartnerGroup estimates that B2B e-commerce will grow from $145
billion in 1999 to $3.9 trillion in 2003, and B2C e-commerce will increase from
$31 billion in 1999 to $381 billion in 2003, representing five-year compound
annual growth rates of 128% and 87%, respectively. In addition, International
Data Corporation, or IDC, estimates the number of Internet purchasers will
increase from approximately 17 million in 1999 to over 80 million in 2003, a
compound annual growth rate of 47%.

    An increasing number of businesses engage e-commerce service providers to
design and implement e-commerce solutions. Although no figures are yet available
on the size of the full-service e-commerce outsourcing market, traditional
e-commerce outsourcing, usually defined as Web site design, strategy consulting,
and software creation and hosting, was a $4.6 billion industry in 1998 and is
expected to grow to $39 billion by 2002 according to IDC representing a compound
annual growth rate of 53%. Furthermore, IDC projects that the world wide market
for Internet professional services will grow from $12.9 billion in 1999 to
$78.6 billion in 2003, representing a compound annual growth rate of
approximately 57%.

    E-COMMERCE AND CUSTOMER RELATIONSHIP MANAGEMENT

    Most companies today recognize that the Internet enables powerful
functionality ranging from display and order processing to complete
supplier-vendor-customer integration and relationship management. As customer
and supplier expectations increase as a result of industry advancement,
companies are forced to take advantage of and develop more sophisticated
Internet applications. With competition only a mouse-click away, organizations
seek to differentiate themselves by providing superior informational and
transactional experiences for their customers through personalized Web sites
that are easy to use and better manage the unique online relationship possible
between the business and its customer.

    Personalized e-commerce enables companies to maintain a unique one-to-one
relationship with customers and suppliers while capturing the efficiency,
affordability and speed of an automated system. Businesses need to track,
collect and store Web site visitor information and transfer that information
across the enterprise to effectively manage the customer relationship in
real-time. We believe that the unique one-to-one relationship established
through personalization enhances the experience of a user and likely will result
in increased traffic and online commerce. Companies that quickly establish
quality one-to-one relationships with online visitors differentiate their
services and potentially gain a competitive advantage.

    CHALLENGES PRESENTED BY E-COMMERCE

    PROVIDING A COMPREHENSIVE SOLUTION.  Creating a comprehensive solution
requires integration among many intricate components. In order to deliver a
dynamic e-commerce experience, companies must integrate Internet applications
with existing content management, customer database, transaction

                                       31
<PAGE>
fulfillment and customer support systems. Visitor experience depends directly on
a company's ability to execute and support the following difficult and complex
activities:

    - integrating back office systems with front-end services to fully utilize
      existing business systems, customer data and information resources;

    - attracting, retaining and servicing a broad demographic range of visitors
      by providing dynamic content, interactive dialogues and communities of
      interest in a friendly, easy-to-use format;

    - developing and maintaining visitor information for tracking and recalling
      specific interactions in a secure and private environment;

    - merchandising services dynamically through personalized content, products
      and incentives to drive increased user visits and transactions;

    - fulfilling transactions with secure e-commerce processes;

    - offering a readily accessible and consistent end-user experience across
      multiple customer touch points, such as call and e-mail centers; and

    - managing product and service distribution, including inventory management,
      product warehousing, order picking and packing, transportation management
      and product returns.

    TIME-TO-MARKET.  In the emerging digital economy, where the first-to-market
often claims significant competitive advantage, speed is essential. Even if
companies have the skilled personnel to implement end-to-end Internet solutions,
the actual development and integration of these solutions with existing
information systems is a very complex and time-consuming process. Solution
design, development and implementation projects frequently range in time from
several months to over a year. Such long implementation lead-time can allow
competitors the opportunity to claim first mover advantage, become the industry
standard and achieve market leadership.

    ADVANCED TECHNOLOGICAL SKILL.  Providing advanced solutions requires the
development, employment and maintenance of leading edge technology and service.
Commitment to being a technological leader requires significant investment of
resources, both initially and over time, in support functions outside a
company's core competence. The diversion of resources from core competencies can
be distracting to an organization and may hamper core business execution.

    TRAINING AND RETAINING HIGH-COST, HIGHLY-SKILLED PERSONNEL.  The
availability of high quality professionals experienced in creating, implementing
and integrating advanced Internet solutions is limited, making the market
extremely competitive for these professionals. As a result, recruiting, training
and retaining experienced professionals are increasingly costly. It is often
inefficient and difficult for companies seeking to implement their own advanced
solutions to hire, train and retain in-house personnel.

    HIGH COST TO DEPLOY AND UPGRADE.  Building, maintaining and upgrading an
Internet commerce platform requires significant initial and ongoing investment.
GartnerGroup reports that the average cost to develop and deploy an Internet
commerce site was $1.0 million in 1999. Often the total costs of ownership
increase significantly due to new technology developments, upgrades and time
involved to develop upgrades and modifications. In order to justify the
investment, companies need a significant return on investment from B2B and B2C
platforms.

    Currently, few companies offer the full range of integrated, comprehensive
e-commerce services necessary for clients to fully capitalize on their
e-commerce potential. Most companies offering outsourced solutions focus on one
or just a few specific services, requiring companies to piece together, or find
a third party to integrate, these disparate solutions. We believe that few, if
any, existing solutions providers offer a comprehensive turn-key and outsourced
approach to critical B2B and B2C e-commerce services. Further, speed, accuracy
and customer experience are essential in the emerging digital economy. Long
implementation lead times in the development and integration of e-commerce
solutions offer faster and more efficient competitors market advantages. Most
businesses cannot afford

                                       32
<PAGE>
to divert internal personnel from their core competencies, while it becomes
increasingly difficult to obtain and retain highly skilled in-house personnel to
implement these advanced solutions.

THE ZENGINE SOLUTION

    Zengine addresses the challenges presented by e-commerce by providing a
comprehensive suite of technology-based solutions that enable our clients to
quickly and cost-effectively create, maintain and enhance their e-commerce
presence on an outsourced basis. Our services for both B2B and B2C e-commerce
include Web site user interface design, product content and merchandising,
personalization and customer relationship management, advertising and
sponsorship management, order management, inventory management and order
fulfillment, end-user customer service and reporting and analysis. Zengine
provides all of these services directly to its clients except for the following
services which are provided by third party vendors through Zengine: inventory
management and order fulfillment which is performed by MCSi, or other third
party vendors, product content and reviews and payment processing.

    Our solution enables our clients to:

    - ACHIEVE RAPID DEPLOYMENT OF E-COMMERCE PLATFORMS. Our services enable our
      clients to quickly establish a fully functional e-commerce environment.
      Our KORE Engine eliminates the need for months of custom programming and
      reduces the time needed to integrate the e-commerce application with the
      client's existing computer systems. As a result, our clients are able to
      drastically reduce their time-to-market. To date, we have enabled our
      clients to conduct e-commerce within an average of 40 days after the
      commencement of our services compared to industry ranges of several months
      to over one year.

    - OPERATE A USER-FRIENDLY E-COMMERCE WEB SITE. Our technology and
      infrastructure provide us with the ability to design and operate a
      client's e-commerce Web site that is:

       - completely integrated with business systems and customer service,
         including inventory management, technical support, customer interaction
         by voice or e-mail and product return processing;

       - consistent with the look, feel and functionality of our client's
         existing Web site and brand strategy;

       - engaging, intuitive, attractive and easy to use by the Web site
         visitor;

       - fast and reliable, to minimize visitor wait time and to maximize
         interactivity;

       - highly personalized, to improve our client's customer relationships by
         dynamically identifying, differentiating and interacting with customers
         on a more personal level; and

       - secured by state-of-the-art procedures that enable execution of
         transactions involving confidential personal and financial data.

    - SAVE ON CAPITAL EXPENDITURES AND FOCUS ON CORE COMPETENCIES. Our clients
      are able to obtain the benefits of e-commerce without making significant
      time and financial investments in hardware, software and technical and
      customer service personnel. We generally provide our solutions from our
      own premises without interfering with our client's daily operations. This
      permits our clients to focus on their core competencies and to leverage
      our knowledge, technology and infrastructure.

    - BENEFIT FROM OUR INTEGRATED, CONTINUAL IMPROVEMENTS. We are engaged in a
      constant process of technological enhancement of our services. These
      improvements include the upgrade of our KORE Engine, new merchandising
      features and advanced browser-based tools. The architecture of KORE is
      designed to automatically and without interruption distribute our service
      improvements to our clients without the need to hire consultants, bring
      the system offline, or install any client-side software. Upon completion,
      the feature or tool can be made available to other Zengine clients without
      added development time or costs. Development under the KORE framework
      contrasts with other e-commerce solutions that provide maintenance and
      upgrades to custom features on an individual and typically labor intensive
      basis.

                                       33

    - INCREASE E-COMMERCE REVENUES THROUGH PERSONALIZED CUSTOMER RELATIONSHIP
      MANAGEMENT. We engage in personalized customer relationship management by
      attempting to optimize each customer visit to our clients' Web sites
      through the use of real time interactive marketing and by attempting to
      resolve customer inquiries and complaints as promptly as possible.
      Interactive personalization consists of capturing permission based
      marketing information from implicit and explicit customer behaviors.
      Examples of visitor information include volunteered data, including
      purchase history, stated preferences, demographic information and
      psychographic information and inferred information, including click-stream
      behavior for predictive modeling. By gathering real time information, we
      are able to personalize the shopping experience by providing product
      suggestions, advertisements, incentives and promotions that are likely to
      be of interest to the visitor. We believe that this personalization of the
      shopping experience results in a higher user conversion ratio (i.e., the
      number of visitors who purchase), increased purchases per visit, increased
      purchase size and greater customer loyalty. This personalized customer
      relationship management capability allows our clients to use the knowledge
      they gain of their customers to strengthen relationships, foster customer
      allegiance and create and sustain a competitive advantage.

    Our solutions incorporate the following distinguishing characteristics:

    - COMPREHENSIVE--We combine Web site user interface design, product content
      and merchandising, personalization and customer relationship management,
      advertising and sponsorship management, order management, inventory
      management and order fulfillment, end-user customer service and reporting
      and analysis in one comprehensive suite of services to better ensure
      accuracy and integration of the entire customer experience.

    - HIGH SPEED--All Web site pages served by Zengine are fastloading,
      regardless of the speed of the user's Internet connection.

    - RELIABLE--Our technology is highly reliable, and is designed to provide
      Web site availability 24 hours a day, 7 days a week and is designed to
      support online database backups and, if necessary, rapid database
      restoration.

    - SCALABLE--Our services allow our clients to deliver consistent quality of
      service as transaction volumes grow and to handle daily and seasonal peak
      periods.

    - FLEXIBLE--Our KORE Engine employs highly flexible modeling and tools to
      facilitate connections between computer applications, including enterprise
      resource planning, inventory management, call center management, supply
      chain management and their underlying databases.

    - REAL TIME--Our solutions process visitor interactions, inventory
      availability, order status and other business rules in real time, reducing
      support costs, bad debt risk and abandoned transactions.

    - SECURE--We use state-of-the-art encryption to provide the security and
      authentication necessary for secure transmission of confidential personal
      and financial information.

    - TRANSPARENT--All visitor interaction occurs on our servers, but appears to
      the customer to be within our client's Web site. This transparency permits
      our clients to operate enterprise wide B2B and B2C e-commerce platforms,
      without the cost of obtaining hardware, software, bandwidth and the
      associated personnel costs of maintaining the system.

STRATEGY

    Our objective is to capitalize on our proprietary technology and
infrastructure, the KORE Engine, to become the leading provider of comprehensive
e-commerce enabling services. To accomplish this goal, we are pursuing a
strategy built on the following initiatives:

    - TARGET COMPANIES SEEKING TO INITIATE, EXPAND OR ENHANCE THEIR ABILITY TO
      CONDUCT E-COMMERCE. We target our sales and marketing efforts on companies
      that are focused on establishing or improving their ability to conduct
      e-commerce yet lack the technical expertise necessary to build and
      implement desired Internet functionality. These may include original
      equipment manufacturers, wholesalers, distributors and other businesses
      that create customized vendor and supply chain relationships, bricks and
      mortar retailers, pure online retailers and Web sites with a large and
      loyal user base, including portals, pure content sites, communities,
      directories and service providers. In order to reach our target customers,
      we intend to substantially increase our sales and marketing efforts. We
      believe that penetration into our target market along with increased
      marketing and trade promotion will establish our brand as the industry
      standard for outsourced e-commerce solutions.

    - EXTEND THE CAPABILITIES OF OUR KORE ENGINE. We intend to extend the
      capabilities of our KORE Engine through continued investment in its
      development to provide for additional functionality, extending our use of
      artificial intelligence, and for vertical applications complementary to
      our current offerings. We believe that our e-commerce services are the
      most comprehensive, efficient and personalized real time solutions on the
      market today. We maintain an open architecture to allow KORE to integrate
      with major operating systems and technologies as they evolve. We intend to
      develop additional capabilities through continued internal development
      and, potentially, through the licensing or acquisition of complementary
      technologies.

    - LEVERAGE CLIENT BASE. One of the distinguishing characteristics of the
      Zengine business model is the constant level of interaction that Zengine
      maintains with its clients. This is in sharp contrast to a software
      solution where the vendor has limited, if any, contact with the client
      after the installation has been completed. The result is that Zengine has,
      and will continue to build, a network of clients that it can leverage. As
      an example, Zengine is currently selling advertising and sponsorship
      packages on client Web sites to advertisers seeking to efficiently deliver
      targeted advertising across our network of e-commerce Web sites. Zengine
      will continue to leverage its network of clients by providing additional
      services or providing access to its client network. These opportunities
      may include additional products or services for Zengine to deliver to its
      network of clients such as relevant content, or may include other
      opportunities to generate revenue through selling access to its network of
      clients to outside sponsors or providers.

    - EXPAND OUR STRATEGIC ALLIANCES. We currently have strategic business
      alliances with Excite@Home, United Stationers Supply Co. and MCSi. We plan
      to continue to develop technology and marketing relationships through
      strategic alliances with software and systems integrators, consulting
      firms, advertising firms and other professional services firms. These
      alliances are intended to complement our direct sales force by providing
      business leads, increasing our geographic coverage and addressing new
      industry segments. We also intend to leverage these relationships to
      commence international sales in countries with high Internet penetration
      and growth rates.

    - ASSIST OUR CLIENTS IN INCREASING THEIR REVENUES USING OUR STATE-OF-THE-ART
      E-COMMERCE SOLUTIONS. Since our revenues are enhanced by increasing the
      sales of our client's products through the e-commerce platforms we
      provide, we intend to enhance the tools our clients use to increase their
      user to buyer conversion rates, increase the number of products per
      purchase and the average value of each purchase. Primary tools used in
      achieving this goal include, increasing the efficiency of our
      personalization technology and merchandising features, such as development
      of more robust, real time predictive models. We anticipate that these
      models will produce higher levels of personalized content and
      merchandising capabilities.

ZENGINE SERVICES AND TOOLS

    ZENGINE SERVICES

    We provide our e-commerce services to clients operating in both B2B and B2C
environments. Our business service enables original equipment manufacturers,
wholesalers and distributors to conduct personalized supply-chain management and
customer transactions over the Internet or secure extranets enabled by Zengine.
Our consumer service enables original equipment manufacturers, bricks and mortar
retailers, online-only retailers and Web sites with a large and loyal user base,
to extend their current business over the Internet.

    Our services focus on customer relationship management and can be generally
separated into six categories.

    - WEB SITE USER INTERFACE DESIGN AND PRODUCT CONTENT. We provide complete
      Web site and product content creation in conjunction with our clients'
      brand strategy. We focus our efforts on designing simple and intuitive
      user-interfaces that leverage rich product content generated by Zengine's
      content group, by third parties and by our clients. Examples of content
      features enabled by KORE include product comparisons, product
      compatibility, related products and accessories and end-user and third
      party reviews. Comprehensive content and enabling features encourage
      visitors to make and increase their online purchases.

    - MERCHANDISING. We provide comprehensive merchandising features designed to
      increase the conversion from browser to buyer, retain loyal customers and
      personalize experiences for one-to-one communication between our clients
      and their customers. Examples of merchandising features enabled by KORE
      include personalization, targeting and profiling, top-seller and user
      rating systems, gift certificates and coupons, outbound communication and
      reporting and analysis.

      Whether within or outside of our client Web sites, we extend our clients'
      brands to outbound e-mail newsletters and advertising, including banners,
      buttons, rich media and affiliate marketing. Scheduled for launch this
      year, we are designing new functionality into KORE that automates our
      targeted e-mail capabilities. Currently, our marketing personnel
      personalize and send targeted e-mails based on customer characteristics
      and preferences.

    - ADVERTISING AND SPONSORSHIP MANAGEMENT. As an outsourced solution, part of
      our service entails the serving of client Web sites. These Web sites may
      include advertisements and sponsorships which drive the visitor deeper
      into the client's Web sites. As a result, we sell advertising and
      sponsorship packages for individual client sites, or across the Zengine
      network of client e-commerce Web sites as a package. Advertising and
      sponsorship packages are sold to brand and direct-marketing advertisers
      seeking to influence targeted visitors within our client e-commerce Web
      sites.

    - ORDER MANAGEMENT. We provide complete order management capabilities for
      clients in a secure environment. Examples of our order management services
      enabled by KORE include universal shopping carts and digital wallets,
      e-mail notifications for account activation, credit card authorizations
      and settlements, inventory availability, order tracking with major
      carriers, tax compliance, and fraud protection. We have entered into
      agreements with VeriSign, Inc. and CyberSource Corporation for credit card
      processing and advanced fraud screening and protection.

      Our order management services include handling all logistics after credit
      cards have been processed. All orders are processed by secure transactions
      via the Internet, by phone, by fax, by mail and/or purchase order. Our
      systems provide the ability for both clients and their customers to track
      the status of orders at any time in real time. This service is transparent
      to our clients' customers and is seamlessly integrated with our clients'
      internal and legacy computer systems.

      For clients that wish to leverage existing enterprise resource planning
      (ERP) systems in their e-commerce platform, Zengine provides an open
      adapter (application programming interface) to KORE that enables seamless
      connections between a client's legacy computer systems and KORE. This
      direct connection, called KOG (KORE Object Gateway), eliminates redundant
      or

                                       36
<PAGE>
      unnecessary human intervention for order management and supports a
      scalable operation designed for long-term growth. A graphic depiction of
      KOG follows:

    FTP box) and "rexstores.com" (connected to the Secure E-mail box).

    The Zengine logo is in the lower right hand corner of the page.]

    - INVENTORY MANAGEMENT AND ORDER FULFILLMENT. On behalf of our clients, we
      have MCSi pick, pack and ship the client's customer orders and provide
      customized private label packaging, inserts and promotional literature for
      distribution with customer orders. Based upon client needs, we are able to
      take advantage of a variety of shipping and delivery options, including
      next day service. These services are delivered through our distribution
      services agreement with MCSi. MCSi, as our agent, receives third party or
      client inventory at its distribution centers, verifies shipment accuracy,
      unpacks, inspects for damage and generally stocks for sale the same day.
      We also utilize the fulfillment services of certain third party
      wholesalers such as Baker & Taylor, Ingram Micro, Ingram Entertainment,
      United Stationers and Valley Media. For clients that wish to leverage
      their existing distribution capabilities, we provide fulfillment messaging
      directly to the client's back office systems for delivery to their
      customers. An integral part of our transaction management services also
      includes the warehousing and distribution of inventory owned by third
      party vendors or our clients and performed by MCSi.

    - END-USER CUSTOMER SERVICE. We provide complete call and e-mail center
      services to our clients internally and under our distribution services
      agreement with MCSi. We believe that an important feature of e-commerce is
      the ability for the end-user to talk with a live customer service
      representative. Our customer support services utilize features that
      integrate voice, e-mail, data and Internet chat communications to respond
      to and handle customer inquiries. Our customer service representatives
      answer questions in our client's name regarding orders, shipping, billing,
      returns and product information as well as a variety of other questions.
      Our customer support center automatically identifies each customer request
      and routes it to the available customer support representative. Our
      customer support centers are designed so that our customer service
      representatives can handle various clients and products, thereby creating
      economies of scale benefits for our clients.

    ZENGINE TOOLS

    Our e-commerce services are customized and maintained using Internet-based
tools accessible by our personnel and by our clients. These tools, called KIT
(KORE Interactive Tool), are accessible through standard Web browser interfaces.
KIT provides a set of building blocks comprised of customizable components,
application templates and rule sets. See the inside back cover page of this

                                       37
<PAGE>
prospectus for a graphic presentation of KIT. These tools are instrumental in
building, rapidly accessing and easily maintaining the Zengine turn-key
e-commerce services. A description of our tools follows:

    - ZENGINE REPORTING AND ANALYSIS. Our reporting and analysis tools allow
      both Zengine and our clients to easily analyze customer and operational
      data. To support this capability, we have designed our reporting and
      analysis tools to extract and manage data from individual client
      e-commerce sites. Once our tools have analyzed the data, they present the
      resulting information in easy-to-use formats, such as graphs and tables.
      Examples of real time reports include client specific reports, including
      inventory management, end-user statistics such as end-user behavior, sales
      trends analysis, per page statistics, references from prior pages and
      search results analysis; advertising and sponsorship campaign reporting
      including discount and voucher creation and reporting, e-mail marketing
      and promotional offer creation and reporting; and call center and customer
      management reporting, which provides real time customer purchase history,
      current shopping cart items and past interaction data.

    - ZENGINE CONTENT MANAGEMENT. This tool allows a distributed and remote team
      of non-technical content editors and merchandising experts to
      collaboratively manage most aspects of site content, including creating,
      editing, staging, production and archiving. This tool provides personal
      and shared in-boxes that enable teams of content creators to collaborate
      in developing content and provides for content previews prior to
      publishing, to control access to publishing and to capture content
      classification information. It supports flat content insertion and adds a
      user-friendly presentation layer to the content by automatically
      generating HTML within the publisher.

    - ZENGINE DESIGN CENTER. We shorten the development cycle by creating
      simple, intuitive user interfaces for client e-commerce Web sites in
      conjunction with their overall brand strategies. By outsourcing the task
      of user interface design to us, our clients are able to focus on other
      strategic issues involved in launching or retro-fitting their e-commerce
      operations. We can provide these services either on a full outsourced
      basis or in collaboration with in-house personnel or other external
      service providers, such as graphic designers or advertising firms. Our
      clients have ultimate authority for user interface and look and feel
      decisions.

    - ZENGINE CALL CENTER. This tool displays real-time customer information for
      call center representatives and general customer service management.
      Customer purchase history and past interaction data are available to
      authorized representatives, as well as a customer's current shopping cart
      items for assistance during checkout. See the inside back cover page of
      this prospectus for a graphic presentation.

CLIENTS

    At June 30, 2000, we had 12 e-commerce clients. We currently have 15
e-commerce clients, which include equipment manufacturers, wholesalers,
distributors and other businesses that create customized vendor and supply chain
relationships, bricks and mortar retailers, pure online retailers and Web sites
that have a large and loyal user base, including portals, pure content sites,
communities, directories and service providers. In addition, we have placed
advertisements for 16 companies. Only MCSi accounted for more than 10% of our
total revenue for the nine month period ended June 30, 2000, while Sharp
accounted for 9.99% of our total revenue for the period. Other clients which
accounted for between 1% and 5% of our total revenue for the nine month period
ended June 30, 2000 included Hitachi, Proxima, Lexmark, Sony, Hewlett-Packard,
Epson, Toshiba and InFocus.

CASE STUDIES

    The following case studies are representative of the services we provide our
clients.

WORK.COM

    CLIENT:  Excite@Home is a global media company offering media services
through the Excite Web site and narrow and broadband subscription services
through @Home for consumers and Work.com, a joint venture between Excite@Home
and Dow Jones & Co., a business services and information portal focused on the
business professional.

    STRATEGIC IMPERATIVE:  Excite@Home was preparing to launch the Work.com Web
site and recognized the opportunity to leverage the capabilities of its
broadband network combined with the retail sales of advanced audio-visual and
video conferencing products to its captive visitors on Work.com. The development
of the proposed e-commerce site had an aggressive time schedule that could not
be realized even by the technology-based company's internal resources. Prior to
the launch of the Work.com Web site, Excite@Home invested $2.0 million in
Zengine in exchange for an equity interest. For more information, please see
"Certain Transactions."

    ZENGINE SOLUTION:  We launched the Work.com Audio-Visual e-commerce store,
the Work.com AV Store, on December 5, 1999, four weeks after initiating
development. Running on our servers, but appearing to be a part of the Work.com
Web site, the Work.com AV Store offers Work.com's business visitors audio,
video, networking, video conferencing, presentation, high speed broadband and
broadcast service products and is found at http://AVStore.Work.com.

    Our agreement with Excite@Home is representative of our strategy to develop
strategic alliances with major industry vendors.

REXSTORES.COM, INC.

    CLIENT:  rexstores.com is a B2C retailer focusing on the sale of consumer
electronics over the Internet. rexstores.com is a wholly-owned subsidiary of REX
Stores Corporation, a New York Stock Exchange listed company and a leading
retailer of consumer electronics and appliances in small to medium market areas
through 238 stores in 35 states. rexstores.com sells its products over its Web
site and on major auction sites.

    STRATEGIC IMPERATIVE:  rexstores.com was searching for a cost-effective way
to make its successful retail Web site even more interactive and to personalize
the visitor experience in order to increase repeat visits and to increase its
conversion (shop/buy) ratios.

    ZENGINE SOLUTION:  We worked closely with rexstores.com's technical team in
redesigning the Web site's user interface and connecting their enterprise
resource systems (primarily inventory and distribution) to the KORE Engine. The
rexstores.com Web site was re-launched within five weeks of the signing of our
agreement and can be found at http://rexstores.com.

    Our collaboration with rexstores.com illustrates how Zengine's experienced
production and engineering team can work closely with an established group of
e-commerce professionals to create significant results-oriented enhancements.
Zengine is able to add value to existing online retailers by providing them with
collaborative planning and tools to increase the effectiveness of their
e-commerce initiatives.

MCSI, INC.

    CLIENT:  MCSi, our parent corporation, is a systems integration and reseller
of state-of-the-art presentation and broadcast facilities, with 1999 annual
revenues of over $680 million.

    STRATEGIC IMPERATIVE:  In a competitive industry, MCSi needs to maintain its
strong position, in part, by developing additional sales channels. MCSi
recognized that it could significantly enhance its

                                       39
<PAGE>
distribution by developing an Internet-based method of selling its products to
its business clients and to retail consumers. MCSi initially implemented an
e-commerce site relying on internal development but quickly realized that we
could significantly strengthen its e-commerce efforts through the application of
our dedicated technical expertise.

    ZENGINE SOLUTION:  We have consulted with and designed MCSi's dedicated Web
sites to permit MCSi to sell its products over its secure extranet to over 1,000
of MCSi's customers at June 30, 2000. These customers log on to MCSi's Web site,
which, based on the work we have performed, appears as a self-branded,
personalized e-commerce extranet mirroring the design of the customers' Web
site. This B2B service provides authorized client users with the right to
purchase specified products from MCSi at preset pricing levels. Under the
administrative services agreement, MCSi employees have the flexibility and
control to update and maintain this Web site under the guidance of Zengine
employees.

    MCSi is now able to offer its customers a way to monitor product purchases
while at the same time making it convenient and seamless for the customers'
employees to obtain the products needed. By serving its clients' extranet pages,
MCSi is able to acquire every purchase transaction made by the customer's
employees.

SALES AND MARKETING

    We market our services through a direct sales force to businesses seeking to
initiate, expand or enhance their ability to conduct e-commerce, including
original equipment manufacturers, wholesalers, distributors and other businesses
that create customized vendor and supply chain relationships over the Internet
or a secure extranet, bricks and mortar retailers, online-only retailers and
major Internet Web sites with a large and loyal user base, including portals,
pure content sites, communities, directories and service providers. Our plan is
to continue to pursue these target clients and to penetrate other markets
through indirect distribution channels such as consulting firms, systems and
integrators, advertising firms and other professional services firms.

    Because we do not promote our own brand to the retail public, we do not
compete with, and are able to serve as a neutral provider of e-commerce services
to, potential and existing clients. This strategy reflects our commitment to
each of our clients' brand preservation and exposure. Our marketing efforts are
two-fold:

    - we promote the value of our outsourced e-commerce services by showcasing
      our clients' success and leadership; and

    - we work cooperatively with clients to promote traffic, revenue and
      long-term loyalty to their e-commerce platforms.

    Our sales activities generally involve meetings with senior management of
the prospective client in order to educate them about how our services will
fulfill their needs. These meetings also involve a hands-on demonstration of our
service capabilities. Because Zengine's brand is "behind the scenes" and because
a client usually must make an enterprise-wide, strategic decision as to which
company it will choose to operate its B2B e-commerce systems or to operate its
B2C e-commerce store or both our sales process typically requires us to compete
with a company's in-house solution and with other e-commerce service vendors. As
a result, the sales cycle is typically long and unpredictable.

    We use a variety of marketing activities to increase market awareness for
our services and educate our target audience. In addition to building brand
awareness with our potential clients, our marketing activities focus on
preparing market research, service offering planning, managing press coverage,
identifying potential clients and generating leads to assist in our direct sales
efforts. To build awareness and attract new clients we seek leads from our
current clients, attend and exhibit at trade shows, build relationships with
industry experts to facilitate networking opportunities, and run cooperative
independent print advertisements in various newspapers, trade journals and
publications. Upon completion of the offering, we intend to greatly expand our
marketing efforts by hiring additional

                                       40
<PAGE>
personnel who will be dedicated to business and market development and public
relations, along with increasing our expenditures for direct marketing,
promotion and co-marketing arrangements with strategic partners.

    An important element of our strategy is to enter into relationships with
software and systems integrators, consulting firms, advertising firms, related
service providers and other professional service firms to assist us in
marketing, selling and delivering our services to potential clients. This
approach is intended to increase the potential for lead generation and access to
large accounts. We currently have strategic alliances with Excite@Home, MCSi,
and United Stationers. Our strategic alliance with Excite@Home is manifested by
our service agreement with them and Excite@ Home's investment in us. The
strategic alliance with United Stationers provides for us to recommend that our
new and existing clients use the services of United Stationer's e-Nited
logistics division and that e-Nited recommend our services to their new and
existing clients. Our strategic alliance with MCSi is based on our affiliation
with MCSi, MCSi's ability to assist us in our marketing efforts by purchasing
products from potential clients in the ordinary course of business, the
agreements we have to provide e-commerce services to MCSi and MCSi's agreement
to provide administrative, distribution and facilities services to us. We are
currently seeking to develop additional strategic alliances. We have vendor
relationships with AboveNet, Cisco Systems, Cybersource, Oracle, pcOrder,
Signio, Sun, Unicast, Verisign, Vertex and Zeus. Zengine does not believe that
any of its vendor relationships is material to its business or results of
operations.

TECHNOLOGY AND INFRASTRUCTURE

    We believe that our proprietary technology and infrastructure, the KORE
Engine, enables us to build, deliver and manage e-commerce solutions in less
time, at lower cost and with greater business success than existing
alternatives. KORE is a robust architecture that allows existing and custom
functionality to be combined in any number of brand iterations seamlessly and
with superior efficiencies.

    THE KORE ENGINE. Zengine's proprietary technology and infrastructure, the
KORE Engine, enables us to build, deliver and manage e-commerce solutions in
less time and more cost effectively than existing alternatives. The functional
components of KORE are stored on a centralized server array which services all
Zengine clients. This architecture minimizes development costs and reduces
time-to-market because we are able to leverage existing functionality previously
developed within KORE rather than re-engineering the functionality for each
application. Upon completion, the component or feature can be made available to
other Zengine clients without added development time or cost. Development within
the KORE framework significantly differs from other e-commerce solutions that
provide maintenance and upgrades to custom features on an individual and
possibly labor intensive basis.

    KORE PERSONALIZATION.  KORE Personalization is the foundation for our
real-time, personalized marketing and customer relationship management
capabilities. To increase conversion and optimization rates of browsers to
buyers, to extend relationship connections between our clients and their
customers, and to build long-term brand loyalty, we enable client Web sites to
adapt product presentation and merchandising features in real-time based on
implicit and explicit visitor information. KORE Personalization applies
predictive algorithms to infer a customer's interests and adapts content
presentation, such as product features, advertisements and pricing, accordingly.
As a customer's experience and interaction with a client's site develops,
personalized content becomes more relevant, ultimately bridging a more personal
relationship between our client and its customer.

    We employ real-time predictive models that compare selected attributes of a
customer's purchase history, behavior, demographics and preferences to the
attributes of large customer populations in detail. Groups of customers
exhibiting attributes similar to the specific customer analyzed are compared to
determine the likely preferences of the customer. In calendar year 2000, we plan
to introduce customizable personal pages, allowing a client's online customers
to personalize the page layout of the

                                       41
<PAGE>
client's site. This feature will also enable client customers to co-brand the
customized layout and operate as an affiliate e-commerce site where other
customers can then shop.

    NETWORK ARCHITECTURE.  KORE resides on a secure, private fault-tolerant
network architecture that provides highly reliable service. This is accomplished
by distributing Internet traffic across an array of servers that are scalable
and redundant. Because of this distributed model, rapid increases in server load
can be quickly scaled by allocating more servers to immediately accommodate
client Web site demand. In addition, our redundant network architecture allows
for unpredictable hardware failure with little effect to service because the
failure merely results in the balanced distribution of server load across the
server array.

    The diagram below depicts a simplified view of our physical network that is
co-located at Above/ Net Communications, a subsidiary of Metromedia Fiber
Network. Above/Net is a Tier 1 Internet Service Provider with multiple OC-48
capacity, offering clear channel circuits across North America.

<PAGE>
    Zengine utilizes distributed and redundant Sun Microsystems Enterprises
Server technology operating in conjunction with Zeus 128-bit secure Web servers
supported by optimized relational and multi-dimensional databases from MySQL.
Since we handle sensitive personal information, we adhere to 1024-bit secure
socket layer (SSL) encryption to provide the highest level of security available
on the market today.

    OPEN SOURCE MOVEMENT.  In order to maximize both personalization and speed
of service, we choose to adhere to open source standards and scalable
programming languages. Development within KORE is done in Perl5, a widely
accepted standard programming language for developing object-oriented software
that is the informed choice for building large-scale e-commerce platforms that
require ongoing and rapid development and high-speed dynamically-generated Web
site operations. MySQL, an open source database, is optimized for speed and
scalability and serves as the foundation for KORE's personalized capabilities.
KORE creates multiple database connections for multiple actions both efficiently
and quickly, resulting in high-speed dynamic Web site delivery.

    The design of our KORE Engine, KOG, KIT and network architecture enables us
to provide rapid, cost-effective and reliable e-commerce solutions by exploiting
the scalability of open source technologies and multi-processor, shared memory
computers.

PRODUCT DEVELOPMENT

    We believe our future success will depend in large part on our ability to
enhance the KORE Engine, develop new products, maintain technological
leadership, and satisfy an evolving range of customer requirements. Our product
development group is responsible for implementing and integrating KORE into our
client's Web sites and business practices, developing content and the user
interface of our client's Web sites, product testing and quality assurance, and
writing product user documentation. In addition, this group supports post-sale
and client account management activities.

    We are currently developing the following products and features, all of
which are scheduled to be available in calendar year 2000.

    - KORE PERSONALIZATION FEATURES--Key features of the next update to the KORE
      Engine will utilize more robust real-time predictive models that we
      anticipate will yield a higher degree of relevant content. Later in
      calendar year 2000, we plan to implement artificially intelligent systems
      that will allow for greater one-to-one personalization across all
      e-commerce environments and customer touch-points.

    - ENHANCED MERCHANDISING FEATURES--We constantly strive to create more
      compelling features that in turn add usability to client e-commerce sites.
      For example, "Recurring Purchases" enables customers to set advance
      schedules for purchase of products based on consumption or scheduling.
      This feature also serves as a data collection point with calendar and
      reminder features.

    - ADVANCED TOOLS--Our services are customized and maintained using KIT,
      browser-based tools easily accessed by our clients via standard Internet
      browsers. We will be launching enhancements to our Reporting and Analysis,
      Content Management and Design Center Tools to further enable our product
      development personnel and our clients to enhance the customization of user
      interfaces, and analysis of traffic, buying habits and trends.

COMPETITION

    The market for our services is intensely competitive and subject to rapid
technological change. We expect competition to intensify in the future. Our
primary source of competition comes from companies who develop their own custom
e-commerce systems or purchase software packages and hire consultants

                                       43
<PAGE>
to implement these solutions. Because these companies have likely made
significant initial investments to develop their custom systems, they may be
less likely to employ outsourced transaction processing strategies. We also face
competition from companies such as Art Technology Group, Breakaway Solutions,
Broadvision, E.piphany, Net Perceptions and USinternetworking. In addition,
other companies may enter the market to provide similar services.

    Many of our competitors have longer operating histories, substantially
greater financial, technical, marketing or other resources, or greater name
recognition than we do. Our competitors may be able to respond more quickly than
we can to new or emerging technologies and changes in customer requirements.
Competition could seriously impede our ability to sell additional services on
terms favorable to us. Our current and potential competitors may develop and
market new technologies that render our existing or future services obsolete,
unmarketable or less competitive. Our current and potential competitors may make
strategic acquisitions or establish cooperative relationships among themselves
or with other e-commerce solution providers or fulfillment companies, thereby
increasing the ability of their services to address the needs of our prospective
customers. Competitive pressures could reduce our market share or require the
reduction of the prices of our services, either of which could materially and
adversely affect our business, results of operations or financial condition.

    We compete on the basis of certain factors, including:

    - technology;

    - time-to-market;

    - breadth of service features and functionality;

    - ease of implementation;

    - speed, accessibility and ease of use;

    - brand recognition;

    - price;

    - system reliability and capacity; and

    - customer support.

    We believe that we presently compete favorably with respect to each of these
factors. However, the market for our services is still rapidly evolving, and we
may not be able to compete successfully against current and potential
competitors.

INTELLECTUAL PROPERTY

    Our ability to compete depends to a large degree upon our proprietary
technology. Our success depends on protecting our intellectual property, which,
next to our employees, is our most important asset. If we do not adequately
protect our intellectual property, our business, financial condition and results
of operations could be seriously harmed. We rely on a combination of trademark
and trade secret rights, confidentiality procedures, licensing arrangements and
contractual restrictions to establish and protect our proprietary rights. These
legal provisions afford only limited protection for our technology. Our source
code for our proprietary software is protected as a trade secret. We have not
applied for a patent for our KORE Engine and have not decided whether to do so
in the future, since the source code would be publicly revealed upon receipt of
any patent. Even if we filed a patent application, we could not assure you that
a patent would be issued.

    We have applied to register our trademarks, such as the Zengine name, the
Zengine "gear" logo, "KORE," "KOG," our tag line "Fueling Your Brand's Commerce
Engine" and "Commerce Engine." However, we cannot assure you that effective
trademark protection will be available for our marks. We

                                       44
<PAGE>
have identified another company that is using the KORE name. We have demanded
that this company stop using our proprietary name. We cannot assure that we will
be successful in these efforts. It is possible that others will adopt product
names or logos similar to KORE or the Zengine gear logo. This would impede our
ability to build our brand identity, lead to customer confusion, increase our
legal expenses and distract management from the operation of our business.

    Finally, we seek to avoid disclosure of our intellectual property by
requiring employees and consultants with access to our proprietary information
to execute confidentiality agreements with us and by restricting access to our
source code. Due to rapid technological change, we believe that factors such as
the technological and creative skills of our personnel, new product developments
and enhancements to existing products are more important than the various legal
protections of our technology to establishing and maintaining a technology
leadership position.

    Despite our efforts to protect our proprietary rights, unauthorized parties
may attempt to copy aspects of our services or to obtain and use information
that we regard as proprietary. Policing unauthorized use of our software is
difficult and while we are unable to determine the extent to which piracy of our
software exists, if at all, software piracy can be expected to be a persistent
problem. Litigation may be necessary in the future to enforce our intellectual
property rights, to protect our trade secrets, to determine the ability and
scope of the proprietary rights of others or to defend against claims of
infringement or invalidity. However, the laws of many countries do not protect
our proprietary rights to as great an extent as do the laws of the United
States. Any such resulting litigation could result in substantial costs and
diversion of resources and could seriously harm our business, operating results
and financial condition. We cannot assure you that our means of protecting our
proprietary rights will be adequate or that our competitors will not
independently develop similar technology. Any failure by us to meaningfully
protect our property could have a material adverse effect on our business.

    To date, we have not been notified that our products infringe the
proprietary rights of third parties, but we cannot assure you that third parties
will not claim infringement with respect to our current or future services or
technology. Because the e-commerce industry is relatively new, patents relating
to the industry are only now starting to be issued by the U.S. Patent and
Trademark Office. These patents are protecting certain business processes which
many in the industry currently believe are not proprietary. We expect that
developers of Web-based commerce products and services will increasingly be
subject to infringement claims as the number of products, services and
competitors in our industry segment grows and as the functionality of products
in different segments of the industry increasingly overlaps. Any such claims,
with or without merit, could be time-consuming to defend, result in costly
litigation, divert management's attention and resources, cause delays or require
us to enter into royalty or licensing agreements. Such royalty or licensing
agreements, if required, may not be favorable or acceptable to us. A successful
claim of infringement against us and our failure or inability to license the
infringed technology or develop or license technology with comparable
functionality could harm our business. See "Risk Factors--Risks Related to Our
Business--We have no patent on the KORE Engine and we may not be able to
adequately protect our proprietary rights."

    We integrate third party software into software we use to perform our
services. This third-party software may not continue to be available on
commercially reasonable terms. We license Internet fraud screen from CyberSource
Corporation and payment processing capabilities from Verisign, Inc. If we cannot
maintain licenses to this third-party software, implementation of our services
could be delayed until equivalent software could be developed or licensed and
integrated into our products, which could materially adversely affect our
business.

FACILITIES

    Our primary offices are located in approximately 17,900 square feet of space
in Fremont, California under a sublease with MCSi expiring on May 1, 2001. For
more information regarding this sublease, refer to the section titled "Certain
Transactions."

EMPLOYEES

    As of June 30, 2000, we had a total of 43 full time and 2 part time
employees, and 6 MCSi employees provide full time, and 15 MCSi employees provide
part time, services to us under the Administrative Services Agreement. Of our
total employees, including those of MCSi, 10 are in management, 25 are in
technology/engineering, 21 are in merchandising/content, and 10 persons are in
sales/marketing, for a total of 66. Our future success will depend, in part, on
our ability to attract, retain and motivate highly qualified technical sales and
management personnel, for whom competition is intense. None of our employees is
represented by a labor union, and we have never experienced a work stoppage. We
consider employee relations to be good.

LEGAL PROCEEDINGS

    We are not a party to any material legal proceedings.

REGULATION

    As e-commerce and the Internet continue to evolve, federal, state and
foreign governments may adopt laws and regulations covering issues such as user
privacy, taxation of goods and services provided over the Internet, pricing,
content and quality of products and services. If enacted, these laws and
regulations could limit the market for e-commerce, and therefore the market for
our services. Although many of these regulations may not apply directly to our
business, we expect that laws regulating the solicitation, collection or
processing of personal or consumer information could indirectly affect our
business.

    The Telecommunications Act of 1996 prohibits certain types of information
and content from being transmitted over the Internet. The prohibition's scope
and the liability associated with a Telecommunications Act violation are
currently unsettled. The imposition upon us and other service providers of
potential liability for information carried on or disseminated through our
applications could require us to implement measures to reduce our exposure to
this liability. These measures could require us to expend substantial resources
or discontinue certain services. In addition, although substantial portions of
the Communications Decency Act were held to be unconstitutional, similar
legislation may be enacted and upheld in the future. It is possible that this
legislation could expose companies involved in e-commerce to liability, which
could limit the growth of e-commerce generally. Legislation like the
Telecommunications Act and the Communications Decency Act could dampen the
growth of Internet usage and decrease its acceptance as a communications and
commercial medium.

    Our applications utilize encryption technology, the export of which is
regulated by the United States government. We currently do not provide our
services to clients located outside the United States, but intend to begin
marketing to foreign companies, or companies who reach foreign markets, in
calendar year 2000. Export regulations, either in their current form or as may
be subsequently enacted, may limit our ability to provide our services outside
the United States. Moreover, federal or state legislation or regulation may
further limit levels of encryption or authentication technology that we are able
to utilize. While we will take precautions against unlawful exportation of our
software, the global nature of the Internet makes it difficult to effectively
control the distribution of software. Any unlawful exportation of our software,
or adoption of new legislation or regulation relating to exportation of software
and encryption technology could have a material adverse effect on our business,
financial condition, and operating results.

                                       46
<PAGE>
    The Internet Tax Freedom Act bars state and local governments from imposing
taxes on Internet access or that would subject buyers and sellers of e-commerce
to taxation in multiple states. This act is in effect through October 2000. When
the act expires or if the act is repealed, Internet access and sales across the
Internet may be subject to additional taxation by state and local governments,
thereby discouraging purchases over the Internet and adversely affecting the
market for our services. On May 10, 2000, the U.S. House of Representatives
passed the Internet Nondiscrimination Act of 2000 which amends the Internet Tax
Freedom Act to prohibit, until October 2006, a state from imposing taxes on
Internet access and multiple or discriminatory taxes on electronic commerce.

    One of the principal features of our proprietary technology is the ability
to identify users who visit our clients' Web sites and to develop and maintain
highly personalized profiles of users to assist our clients in determining the
nature of the content and the product offerings to be provided to that customer.
Typically, users are identified through the use of "cookies" and other
non-personally-identifiable information. Profiles are captured when customers
visit a site on the Web and volunteer information in response to survey
questions concerning their backgrounds, interests, and preferences, with prior
notice, and the opportunity for a user to opt-out of such targeting and
collection. Profiles are augmented over time through the collection of usage
data. Privacy concerns may cause users to resist providing the personal data
necessary to support this profiling capability. The perception by our clients'
customers or potential customers of substantial security and privacy concerns,
whether or not valid, may inhibit market acceptance of our technology. Such
concerns also may be heightened by legislative or regulatory requirements that
require notification to Web site users that the data captured as a result of
visitation of certain Web sites may be used by marketing entities to
unilaterally address product promotion and advertising to that user.

    We are subject to various federal and state regulations concerning the
collection and use of information regarding individuals who access Web sites.
These laws include the Children's Online Privacy Protection Act, federal and
state consumer credit laws, as well as other laws that govern the collection and
use of consumer information. Since many of the proposed laws or regulations are
just being developed, and a consensus on privacy and data usage has not been
reached, we cannot yet determine the impact these regulations may have on our
business. In addition, the U.S. Congress, a number of state governments and
various trade organizations and industry groups have recently proposed
limitations on the collection and use of information regarding Internet users.
Although our compliance with applicable federal and state laws, regulations and
industry guidelines has not had a material adverse effect on us, if governments,
trade associations and industry self-regulatory groups enact more burdensome
laws, regulations and guidelines relating to consumer privacy, its could
materially and adversely affect our business, financial condition and results of
operations.

    Certain consumer activist groups have recently sought to have the Federal
Trade Commission determine whether profiling should be considered "subliminal"
marketing which they believe should be prohibited. While we are not aware of any
law or regulation which prohibits subliminal marketing, the FTC has, in the
past, considered such acts to be deceptive trade practices and has issued
administrative cease and desist orders against companies using those techniques.
The FTC has recently begun an informal inquiry into the business practices of an
Internet marketing and advertising company that uses personalization techniques
to target advertisements to people who browse certain Web sites. That company is
also currently defending itself against seven private lawsuits alleging, among
other things, the improper collection and use of personal information in
violation of federal and state statutes and the right of privacy. In addition,
the Attorney General's Office of the States of New York and Michigan have
requested that this company provide certain information concerning its business
practices. Zengine is not involved in any similar investigation or litigation.
However, if the privacy concerns of consumers are not adequately addressed, our
business could be harmed.

BOARD STRUCTURE AND COMMITTEES

    Under the amended and restated certificate of incorporation, our board of
directors will be divided into three classes serving staggered terms. Directors
in each class will be elected to serve for three-year terms and until their
successors are elected and qualified. Each year, the directors of one class will
stand for election as their terms of office expire. Presently, Mr. Hutchison and
Ms. Snider are designated as the Class I directors, with their terms of office
expiring in 2001; Messrs. Hopple and Liberati are designated as Class II
directors, with their terms of office expiring in 2002; and Messrs. Savarino and
Peppel are designated as Class III directors, with their terms of office
expiring in 2003.

    We have three standing committees: an executive committee, an audit
committee and a compensation committee. Messrs. Peppel, Savarino and Liberati
have been appointed as the initial members of the executive committee.
Messrs. Liberati and Hopple and Ms. Snider have been appointed as the initial
members of the audit committee. Messrs. Liberati, Hopple and Hutchison have been
appointed as the initial members of the compensation committee.

    The executive committee generally has the authority to act as the board of
directors when the board is not in session, subject to certain exceptions
contained in the Delaware General Corporation Law. Actions of the executive
committee may be taken upon the affirmative vote of any two of the three members
of the committee, provided that one of the committee members so acting must be a
non-employee director. Executive committee decisions must be ratified by the
board of directors at its next regularly scheduled meeting. The audit committee
will select the independent public accountants to audit our annual financial
statements and will establish the scope and oversee the annual audit. The
compensation committee will determine the compensation for employee directors
and, after receiving and considering the recommendation of our president and
chief executive officer, all officers of the company and any other employee that
the compensation committee may designate from time to time and will approve and
administer employee stock option and incentive plans. Our board of directors may
establish other committees from time to time to facilitate the management of the
business and affairs of our company.

NON-EMPLOYEE DIRECTOR COMPENSATION

    Each non-employee director receives a fee of $1,000 for each meeting of the
board of directors or a board committee which he or she attends, plus his or her
expenses related to attendance. Non-employee directors will receive an initial
grant of stock options to purchase 81,223 shares of common stock under the 1999
Stock Option Plan upon the closing of the initial public offering with an
exercise price per share equal to the initial public offering price.
Non-employee directors are also eligible to receive future discretionary grants
under the plan. Directors who are also employees of Zengine receive no payment
for serving as directors or committee members.

EXECUTIVE COMPENSATION

    The following table sets forth certain compensation information for our
chief executive officer and our four other most highly compensated executive
officers for services rendered in all capacities to Zengine during the year
ended September 30, 1999. These executives are referred to as the named
executive officers in this prospectus.

(1) Represents the grant of 676,860 shares of restricted stock, which had a fair
    market value of $60,000 on the date of grant and at September 30, 1999.
    One-third (225,620) of the shares vested immediately upon grant in
    March 1999 and 34,711 shares vest each calendar quarter thereafter (the
    remainder of the unvested shares will vest upon completion of this
    offering).

    Messrs. Savarino, Dhadphale and Feaver are subject to employment agreements
which provide each of them an annual salary of $90,000. For more information,
please see "Employment Agreements." During fiscal 1999, Mr. Lipinski was
employed by MCSi and he did not become an employee of ours until January 1,
2000. Mr. Lunt joined Zengine on November 1, 1999 at an annual salary of
$100,000.

EMPLOYMENT AGREEMENTS

    We have entered into multi-year employment agreements with Joseph Savarino,
our President and Chief Executive Officer, Christopher Feaver, our Chief
Technology Officer, and Lalit Dhadphale, our

                                       51
<PAGE>
Vice President of Product Development and Chief Operating Officer. Each
employment agreement is substantially the same and provides for the following:

    - a three year term which ends in March 2002, with automatic one-year
      renewals;

    - $90,000 annual base salary;

    - 676,860 restricted shares of our common stock, of which 225,620 shares
      vested upon execution of the employment agreement and 34,711 shares which
      vest each calendar quarter; upon a change in control of our company, which
      is defined to include the completion of this offering, the restricted
      shares will immediately vest;

    - participation in any benefit or retirement plans offered by us;

    - severance pay under certain circumstances which is capped at $14,795;

    - an agreement to keep our proprietary information confidential during the
      term of the employment agreement and for a period of seven years following
      termination of the employment agreement; and an agreement to not compete
      with us in an area within a 75 mile radius of any existing office of ours
      or MCSi during the term of the employment agreement and for twelve months
      following March 1, 2002; and

    - indemnification by us of the executive for actions in which the executive
      is made a party or is otherwise involved by reason of being or having been
      a director, officer, employee or agent of Zengine, MCSi or any affiliates
      of either.

1999 STOCK OPTION PLAN

    The Amended and Restated 1999 Stock Option Plan provides for the grant of
stock options to all employees and directors of our company, our subsidiaries
and of MCSi who are eligible to participate. The purpose of the 1999 Stock
Option Plan is to further our growth, development and financial success by
providing incentives to our employees and non-employee directors and employees
of our parent corporation, MCSi, by assisting them to become owners of our
common stock. An aggregate of 3,384,300 shares of common stock are reserved for
issuance to employees and directors under the 1999 Stock Option Plan.

    The 1999 Stock Option Plan is administered by a committee of our Board of
Directors (the "1999 Stock Option Committee"). The 1999 Stock Option Committee
consists of two or more directors, appointed by our board of directors, who are
"non-employee directors," as defined in Rule 16b-3 under the Securities Exchange
Act of 1934, and "outside directors," as defined in Section 162(m) of the
Internal Revenue Code. The 1999 Stock Option Committee has complete authority
and discretion to determine from among eligible persons those to whom options
will be granted and the number and terms of such options. The current members of
the 1999 Stock Option Committee are Mr. Liberati, Mr. Hutchison and Mr. Hopple.

    The 1999 Stock Option Plan provides for the granting of both incentive stock
options and non-qualified stock options under the Internal Revenue Code.
Non-employee directors are eligible to receive only non-incentive stock options
under the plan. The exercise price of incentive stock options granted under the
1999 Stock Option Plan may not be less than 100% of the fair market value on the
date of the grant, except that incentive stock options granted to individuals
owning more than ten percent of the total combined voting power of Zengine may
not have an exercise price less than 110% of the fair market value on the date
of grant. The exercise price of non-qualified stock options is established by
the 1999 Stock Option Committee. Unless otherwise provided for by the 1999 Stock
Option Committee or our Board of Directors, and set forth in the individual
stock option agreements, stock options under the 1999 Stock Option Plan vest
over four years, with 25% vesting one year from the date of grant and 6.25%
vesting each calendar quarter thereafter. Unless otherwise provided for by

                                       52
<PAGE>
the 1999 Stock Option Committee or our Board of Directors, stock options issued
under the 1999 Stock Option Plan immediately vest and become exercisable upon
the option holder's death, disability or upon a change of control of Zengine, as
defined in the 1999 Stock Option Plan.

    Payment of the exercise price of a stock option may be made in cash, shares
of common stock, or by any other method approved by the 1999 Stock Option
Committee, consistent with Section 422 of the Code and Rule 16b-3 under the
Exchange Act. Incentive stock options are not assignable or transferable except
by will or the laws of descent and distribution, and, during the participant's
lifetime, may be exercised only by the participant. However, an optionee may
transfer non-qualified stock options to his or her spouse, lineal ascendants,
lineal descendants, or to a duly established trust for the benefit of one or
more of these individuals.

    At the time of any merger, consolidation, reorganization, recapitalization,
stock dividend, stock split, or other change in the corporate structure or
capitalization affecting our common stock, appropriate adjustments to the
exercise price, number and kind of shares to be issued under the 1999 Stock
Option Plan and any outstanding options will be made. Unless terminated earlier,
the 1999 Stock Option Plan will terminate ten years from its adoption, and no
stock options will be granted after the 1999 Stock Option Plan terminates. Our
board of directors has the authority to amend, modify, suspend or terminate the
1999 Stock Option Plan at any time, subject to any requirement of stockholder
approval under the Internal Revenue Code or other applicable law or rule of the
Nasdaq Stock Market, and, if applicable, approval by an optionee whose options
would be adversely affected by the change.

    There are currently an aggregate of 1,380,118 options outstanding under the
1999 Stock Option Plan at a weighted average exercise price of $.89 per share.

    The following table sets forth information with respect to grants of stock

AGGREGATE OPTION EXERCISES IN LAST FISCAL YEAR AND FISCAL YEAR-END OPTION VALUES

    None of the named executive officers have exercised options to purchase

September 30, 1999.

    The "Value of Unexercised In-the-Money Options at September 30, 1999" is

EMPLOYEE STOCK PURCHASE PLAN

    We have adopted the 2000 Employee Stock Purchase Plan which will become
effective upon the completion of this offering. The Stock Purchase Plan provides
employees with the opportunity to purchase shares of our common stock on a
regular basis. The purpose of the Stock Purchase Plan is to contribute to our
growth and profitability by allowing our employees to purchase common stock
which will provide them with an incentive to work towards the success of
Zengine. The Stock Purchase Plan is intended to qualify as an employee stock
purchase plan within the meaning of Section 423 of the Internal Revenue Code.
Pursuant to the plan, shares of common stock will be offered to employees of
Zengine in up to two phases known as "offering periods" during which payroll
deductions will be accumulated under the plan during any calendar year.
Generally, there will be two six month offering periods each year. An employee
shall elect to make contributions to the plan by payroll deductions in an
aggregate amount up to 15% of such employee's total compensation. Employees may
not make any separate cash payment to purchase shares pursuant to the plan. On
the first business day of each offering period, Zengine will grant to each
eligible employee who is then a participant in the plan an option to purchase
shares of the common stock at an option price determined by the committee, which
shall not be less than eighty-five percent (85%) of the lesser of (a) the fair
market value of the shares on the first business day of an offering period, or
(b) the fair market value of the shares on the last business day of such
offering period. Shares are purchased on the last day of the offering period.
The common stock purchasable under the Stock Purchase Plan may be shares of
authorized but unissued shares, treasury shares or shares purchased by Zengine
on the open market or from private sources for use under the Stock Purchase
Plan. The maximum number of shares which may be issued over the term of the
Stock Purchase Plan is 100,000, which is subject to anti-dilution provisions.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

    The members of our compensation committee are Messrs. Hutchison, Liberati
and Hopple. Mr. Liberati also served as the member of the compensation committee
of MCSi until his retirement in February 2000.

LIMITATION OF LIABILITY AND INDEMNIFICATION OF OFFICERS AND DIRECTORS

    Our amended and restated certificate of incorporation and amended and
restated bylaws provide that the personal liability of our directors and
officers shall be eliminated to the fullest extent authorized by Delaware law.
Our amended and restated certificate of incorporation and amended and restated
bylaws further provide that our directors and officers shall be indemnified by
us to the fullest extent authorized by Delaware law. We intend to obtain
insurance which insures our directors and officers against specified losses and
which insures us against specific obligations to indemnify our directors and
officers.

                              CERTAIN TRANSACTIONS

RELATIONSHIP WITH MCSi

    Our operations began in January 1999 as a division of MCSi, known as
BuySupply.com, which commenced operations as a branded computer supplies and
accessories e-commerce Web site selling MCSi's inventory. Shortly thereafter,
Messrs. Savarino, Dhadphale and Feaver agreed to combine their prior Internet
experience with funding from MCSi to create an e-commerce services company based
on our current business model. We were subsequently incorporated on March 2,
1999. After the completion of this offering, MCSi will own approximately 50.7%
of the outstanding shares of common stock, or approximately 48.9% if the
underwriters exercise their over-allotment option in full.

    As a subsidiary, we have received various services provided by MCSi,
including administration (i.e., payroll, human resources, cash management,
benefit administration, etc.), warehousing and distribution, and property and
equipment. In addition, we have received the services of certain MCSi employees,
including, in particular, Michael E. Peppel, MCSi's chairman, president and
chief executive officer and Ira H. Stanley, its vice president and chief
financial officer. In consideration for these services, MCSi has historically
allocated a portion of its overhead costs related to such services to us. We
cannot assure you that the prices charged to us, or the overall terms and
conditions under these agreements are not higher or lower than the prices that
may be charged by unaffiliated third parties for similar services. Therefore,
the transactions might have been on less favorable terms than would have been
obtained from an unaffiliated third party.

    We have entered into certain agreements with MCSi related to administrative
services, distribution services, e-commerce services and a premises and
equipment lease. A summary description of each of these agreements is set forth
below. You should read the full text of these agreements, which have been filed
with the SEC as exhibits to the registration statement of which this prospectus
is a part.

    All of our agreements with MCSi were made in the context of a
parent-subsidiary relationship. Although we generally believe that the terms of
these agreements are consistent with fair market values, we have had no
appraisals or valuations performed and therefore we cannot assure you that the
prices charged to us, or by us, under these agreements are not higher or lower
than the prices that may be charged by, or to, unaffiliated third parties for
similar services.

    MCSi has advised us that it intends to evaluate, from time to time,
alternatives to maximize, for the benefit of its stockholders, the value of its
Zengine shareholdings. These alternatives could include retention of all or a
portion of its shareholdings, the sale in one or more transactions of all or a
portion of its shareholdings, the distribution of its shareholdings to MCSi
shareholders (which may be in the form of a tax free spin-off under Section 355
of the Internal Revenue Code), the issuance of debt or equity securities that
will enable MCSi to monetize all or a portion of its investment in Zengine or
other transactions. We cannot assure you as to which alternative MCSi may choose
or whether or when any such transaction will occur, if at all.

    ADMINISTRATIVE SERVICES AGREEMENT.  Since our formation, we have obtained
many of our administrative services from MCSi. In anticipation of this offering,
effective October 1, 1999, we entered into a two-year agreement with MCSi where
MCSi will provide us with services relating to accounts payable, human resources
and compensation, corporate development, employee benefit administration,
treasury and cash management, risk and insurance management, executive
compensation and benefit plan design, benefit administration, Web site
population services and tax planning. In consideration for providing these
services, we will pay MCSi $60,000 per month. The administrative services
agreement is terminable by either party under a number of circumstances. This
agreement is renewable by mutual agreement between Zengine and MCSi.

    DISTRIBUTION SERVICES AGREEMENT.  We offer product distribution, fulfillment
and warehousing, customer service and other related services to our clients as
part of our e-commerce service offerings.

                                       55
<PAGE>
Effective October 1, 1999, we entered into a two year non-exclusive Distribution
Services Agreement with MCSi by which MCSi will provide these services to our
clients. Under the agreement, we will pay MCSi a service fee equal to three
percent (3%) of the total gross revenues for any product order fulfilled, for
third party customers, wholly or partly by MCSi (plus certain costs incurred by
MCSi.) If product is purchased from MCSi, Zengine will pay MCSi the actual
retail list price of that product plus the actual cost of freight paid by MCSi.
We subsequently amended the agreement to pay MCSi for warehouse space an amount
equal to a percentage of MCSi's gross expenses relating to the operation of the
warehouse for us through the end of the term of the agreement.

    E-COMMERCE SERVICES AGREEMENT.  Effective October 1, 1999, we entered into
an e-commerce services agreement with MCSi in which we will provide certain
design, enhancement and ongoing maintenance services relating to MCSi's B2B
dedicated Web sites for a period of two years. MCSi will pay us ten percent
(10%) of the revenue derived from product sales on the MCSi Web sites we
service.

    PROPERTY SUBLEASE AND EQUIPMENT LEASE AGREEMENT.  Effective October 1, 1999,
we entered into an agreement to sublease our main office and to lease certain
equipment, including chairs, desks, cubicle offices and computers, from MCSi.
The agreement provides for monthly payments of $2,083 for the equipment lease
and $10,417 for the property sublease, and expires on May 1, 2001.

TRANSACTIONS WITH WILBLAIRCO ASSOCIATES, AT HOME CORPORATION, MCSI AND CERTAIN
  STOCKHOLDERS

    On October 1, 1999, we entered into an agreement to sell 902,478 shares of
our common stock to each of Wilblairco Associates and At Home Corporation for
$2.0 million each (the "investment transactions"), which was completed in
October 1999. Wilblairco Associates, an Illinois general partnership, is an
affiliate of William Blair & Company, which is the lead underwriter of this
offering.

    In conjunction with our sale of equity to Wilblairco Associates and At Home
Corporation, we entered into a Registration Rights Agreement and a Stockholders
Agreement and MCSi entered into Put Agreements with Wilblairco and At Home. We
subsequently entered into a warrant agreement with REX Stores Corporation, in
conjunction with our agrement to provide e-commerce services to rexstores.com,
Inc., a subsidiary of REX Stores, where we agreed to provide REX Stores with the
same registration rights as we gave to Wilblairco and At Home.

    REGISTRATION RIGHTS AGREEMENT.  At any time after 180 days after we complete
our first public offering of common stock where the aggregate price less
underwriters' and brokers' commissions and certain expenses equals
$25.0 million or more and results in our common stock being listed on the New
York Stock Exchange, American Stock Exchange or the Nasdaq Stock Market (a
"qualified public offering"), Wilblairco, At Home, MCSi, Joseph Savarino, Lalit
Dhadphale, Christopher Feaver and/or REX Stores (the "registration rights
holders") may request registration (a "demand registration") of at least
$15.0 million of our common stock held by them. We are not obligated to effect
more than one demand registration in any six month period and, subject to
certain conditions, we will not be obligated to effect more than three demand
registrations overall. The registration rights holders also have the right,
subject to certain conditions, to include their shares of our common stock in
any registered offering of our common stock that we make (an "incidental
registration").

    The ability of the registration rights holders to request demand
registration of their Zengine common stock is subject to the opinion of the
managing underwriter of the proposed offering that the number of shares desired
to be sold exceeds the number of shares which can be sold in the offering or is
reasonably likely to materially and adversely affect the success or offering
price of such offering. If the underwriter makes this determination, the shares
will be included in the offering in the following priority:

    - first, shares of the registration rights holders pro rata on the basis of

      third person.

If the managing underwriter makes the same determination in connection with an
incidental registration, the shares will be included in the offering in the
following priority:

    - shares requested to be included by us;

    - next, shares of the registration rights holders pro rata on the basis of
      the shares requested to be included by each; and

    - next, shares of the holders of any other registration rights granted by us
      in writing, pro rata in accordance with the number of such securities each
      such holder has requested to be included in the registration.

    In addition to the registration priorities discussed in the preceding
paragraph, the registration rights agreement prohibits us from granting
registration rights to any other person, unless the agreement(s) providing for
the rights specifically provides that the holders of the rights ("third party
rights") may not participate in any demand or incidental registration unless the
underwriters of the distribution confirm that the inclusion of the securities
proposed to be included under the third party rights will not materially
adversely affect the offering. We may, however, grant third party rights to a
person who has purchased our securities for an aggregate of at least
$2.0 million prior to a qualified public offering which rights may allow
participation in a demand registration as though such person was a registration
rights holders.

    The registration rights agreement sets forth various registration
procedures. It also provides that we will pay all reasonable expenses related to
all demand and incidental registrations other than underwriters discounts and
commissions. The registration rights agreement also contains indemnification and
contribution provisions by us for the benefit of the registration rights
holders, their affiliates and any underwriters, and limited indemnification
provisions by the registration rights holders for the benefit of us and any
underwriters. The rights in the registration rights agreement may not be
assigned by a registration rights holder without our prior consent, which will
not be unreasonably withheld.

    PUT AGREEMENTS.  MCSi entered into put agreements with each of Wilblairco
and At Home which provide that during a period of two years commencing on
September 30, 2002, Wilblairco and At Home each have the right, from time to
time, to require MCSi to purchase all or a portion of their shares purchased in
the investment transactions at a purchase price of $3.37 per share. The rights
in the put agreements are not transferable and are subject to anti-dilution
provisions. The put agreements will terminate upon the completion of this
offering.

    STOCKHOLDERS AGREEMENT.  The stockholders agreement between Wilblairco, At
Home, MCSi, Zengine, Joseph Savarino, Lalit Dhadphale, Christopher Feaver and
REX Stores specifies and limits the manner and terms upon and by which the
shares outstanding as of September 30, 1999 shall or may be transferred in
certain circumstances. The stockholders agreement will terminate upon the
completion of this initial public offering.

    We believe that the transactions with Wilblairco Associates, At Home
Corporation, MCSi and certain of our stockholders and REX Stores described
immediately above were made on terms no less favorable to us than we could have
obtained from unaffiliated third parties. All future transactions between us and
our directors, officers, principal stockholders and their affiliates will be
approved by a majority of the independent and disinterested outside members of
our board of directors, but we cannot assure you that future transaction will be
on terms no less favorable to us than could be obtained from unaffiliated third
parties.

      of our outstanding stock;

    - each of the named executive officers;

    - each of our directors; and

    Under the rules of the Securities and Exchange Commission, beneficial
ownership includes voting or investment power with respect to securities and
includes the shares issuable under stock options that are exercisable within
sixty (60) days of June 30, 2000. Shares issuable under stock options are deemed
outstanding for computing the percentage of the person holding options but are
not outstanding for computing the percentage of any other person. The number of
shares of common stock outstanding after this offering includes shares of common
stock being offered for sale by us in this offering. The percentage of
beneficial ownership for the following table is based upon 12,183,480 shares of
common stock outstanding as of June 30, 2000, and 16,473,480 shares of common
stock outstanding after the completion of this offering assuming no exercise of
the underwriters' overallotment option. As of June 30, 2000, the Company had six
stockholders.

    The address for each of the stockholders listed in the table, other than
MCSi, Wilblairco Associates and At Home Corporation, is c/o Zengine, Inc., 6100

                          DESCRIPTION OF CAPITAL STOCK

    Under our amended and restated certificate of incorporation, which will be
effective prior to the completion of this offering, our authorized capital stock
consists of 120,000,000 shares, of which 100,000,000 shares are common stock, no
par value per share, and 20,000,000 shares are preferred stock, no par value per
share, of which none are outstanding. Immediately following this offering,
16,473,480 shares of common stock, or 17,058,480 shares if the underwriters
exercise their over-allotment option in full, will be outstanding. The following
description of our capital stock is qualified in its entirety by our amended and
restated certificate of incorporation and amended and restated bylaws, both of
which are included as exhibits to the registration statement of which this
prospectus forms a part.

COMMON STOCK

    Holders of our common stock will be entitled to one vote per share with
respect to each matter presented to our stockholders on which the holders of
common stock are entitled to vote. Except as may be provided in connection with
any preferred stock in a certificate of designation filed pursuant to the
Delaware General Corporation Law (DGCL), or as may otherwise be required by law
or the amended and restated certificate of incorporation, the common stock will
be the only capital stock of Zengine entitled to vote in the election of
directors and on all other matters presented to our stockholders; provided that
holders of common stock, as such, will not be entitled to vote on any matter
that relates solely to the terms of any outstanding series of preferred stock or
the number of shares of such series and does not affect the number of authorized
shares of preferred stock or the powers, privileges and rights pertaining to the
preferred stock. The common stock does not have cumulative voting rights.

    Subject to the prior rights of holders of preferred stock, if any, holders
of common stock are entitled to receive such dividends as may be lawfully
declared from time to time by our board of directors. Upon any liquidation,
dissolution or winding up of Zengine, whether voluntary or involuntary, holders
of common stock will be entitled to receive such assets as are available for
distribution to stockholders after there shall have been paid or set apart for
payment the full amounts necessary to satisfy any preferential or participating
rights to which the holders of each outstanding series of preferred stock are
entitled by the express terms of such series.

    The outstanding shares of our common stock are, and the shares of common
stock being offered hereby will be, upon payment therefor, validly issued, fully
paid and nonassessable. The common stock sold in this offering will not have any
preemptive, subscription or conversion rights. Additional shares of authorized
common stock may be issued, as determined by our board of directors from time to
time, without stockholder approval, except as may be required by applicable law
or stock exchange or Nasdaq Stock Market requirements.

PREFERRED STOCK

    Our board of directors is empowered, without approval of the stockholders,
to cause shares of preferred stock to be issued from time to time in one or more
series, with the numbers of shares of each series and the designation, powers,
privileges, preferences and rights of the shares of each such series and the
qualifications, limitations and restrictions thereof as fixed by our board of
directors. Among the specific matters that may be determined by our board of
directors are:

    - the designation of each series;

    - whether the shares of each series has voting rights;

    - the rate of dividends, if any

                                       59
<PAGE>
    - whether dividends, if any, shall be cumulative or non-cumulative;

    - the terms of redemption, if any;

    - the amount payable in the event of any voluntary or involuntary
      liquidation, dissolution or winding up of the affairs of Zengine;

    - rights and terms of conversion or exchange, if any;

    - the price for which the shares may be issued;

    - restrictions on the payment of dividends on redemptions of stock while any
      shares of such series is outstanding; and

    - any other powers, preferences and other special rights or qualifications
      on limitations.

    Although no shares of preferred stock are currently outstanding and we have
no current plans to issue preferred stock, the issuance of shares of preferred
stock, or the issuance of rights to purchase such shares, could be used to
discourage an unsolicited acquisition proposal. For example, a business
combination could be impeded by the issuance of a series of preferred stock
containing class voting rights that would enable the holder or holders of such
series to block any such transaction. Alternatively, a business combination
could be facilitated by the issuance of a series of preferred stock having
sufficient voting rights to provide a required percentage vote of the
stockholders. In addition, under certain circumstances, the issuance of
preferred stock could adversely affect the voting power and other rights of the
holders of the common stock. Although our board of directors is required to make
any determination to issue any such stock based on its judgment as to the best
interests of the stockholders of Zengine, it could act in a manner that would
discourage an acquisition attempt or other transaction that some, or a majority,
of the stockholders might believe to be in their best interests or in which
stockholders might receive a premium for their stock over prevailing market
prices of such stock. Our board of directors does not at present intend to seek
stockholder approval prior to any issuance of currently authorized stock, unless
otherwise required by law or applicable stock exchange or Nasdaq Stock Market
requirements.

WARRANT

    As of June 30, 2000, there was an agreement to issue one warrant to purchase
1.7% of the issued and outstanding shares of our common stock immediately after
our initial public offering. We agreed to issue this warrant in January 2000 to
REX Stores Corporation contingent upon completion of a successful initial public
offering at an exercise price equal to the initial public offering price per
share. The warrant will be issued and become immediately exercisable immediately
after the closing of our initial public offering. It will expire three years
after its date of issue.

LIMITATION OF LIABILITY OF DIRECTORS

    Our amended and restated certificate of incorporation provides that the
personal liability of our directors for monetary damages shall be eliminated to
the fullest extent provided by the DGCL. Section 102(b)(7) of the DGCL states,
that a director of Zengine will not be personally liable to Zengine or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability imposed by law, as in effect from time to time:

    - for any breach of the director's duty of loyalty to Zengine or its
      stockholders;

    - for any act or omission not in good faith or which involved intentional
      misconduct or a knowing violation of law; or

    - for any transaction from which the director derived an improper personal
      benefit.

                                       60
<PAGE>
    The inclusion of this provision in the amended and restated certificate of
incorporation may have the effect of reducing the likelihood of derivative
litigation against directors, and may discourage or deter stockholders or
management from bringing a lawsuit against directors for breach of their duty of
care, even though such an action, if successful, might otherwise have benefited
Zengine and its stockholders.

    Our amended and restated certificate of incorporation also requires that
Zengine provide indemnification to its directors, officers and employees to the
extent currently permitted by the DGCL.

SECTION 203 OF THE DELAWARE GENERAL CORPORATION LAW AND BYLAWS

    We are a Delaware corporation and subject to Section 203 of the DGCL.
Generally, Section 203 prohibits a publicly held Delaware corporation from
engaging in a "business combination" with an "interested stockholder" for a
period of three years after the time such stockholder became an interested
stockholder unless certain conditions are satisfied. Thus, this provision may
make acquisition of control of Zengine more difficult. The prohibitions in
Section 203 of the DGCL do not apply if:

    - prior to the time the stockholder became an interested stockholder, the
      board of directors of the corporation approved either the business
      combination or the transaction which resulted in the stockholder becoming
      an interested stockholder;

    - upon consummation of the transaction which resulted in the stockholder
      becoming an interested stockholder, the interested stockholder owned at
      least 85% of the voting stock of the corporation outstanding at the time
      the transaction commenced; or

    - at or subsequent to the time the stockholder became an interested
      stockholder, the business combination is approved by the board of
      directors and authorized by the affirmative vote of at least 66 2/3% of
      the outstanding voting stock that is not owned by the interested
      stockholder.

    Under Section 203 of the DGCL, a "business combination" includes:

    - any merger or consolidation of the corporation with the interested
      stockholder;

    - any sale, lease, exchange or other disposition, except proportionately as
      a stockholder of such corporation, to or with the interested stockholder
      of assets of the corporation having an aggregate market value equal to 10%
      or more of either the aggregate market value of all the assets of the
      corporation or the aggregate market value of all the outstanding stock of
      the corporation;

    - certain transactions resulting in the issuance or transfer by the
      corporation of stock of the corporation to the interested stockholder;

    - certain transactions involving the corporation which have the effect of
      increasing the proportionate share of the stock of any class or series of
      the corporation which is owned by the interested stockholder; or

    - certain transactions in which the interested stockholder receives
      financial benefits provided by the corporation.

    Under Section 203 of the DGCL, an "interested stockholder" generally is:

    - any person that owns 15% or more of the outstanding voting stock of the
      corporation;

    - any person that is an affiliate or associate of the corporation and was
      the owner of 15% or more of the outstanding voting stock of the
      corporation at any time within the three-year period prior to the date on
      which it is sought to be determined whether such person is an interested
      stockholder; and

    - the affiliates or associates of any such person.

                                       61
<PAGE>
    Because MCSi owned more than 15% of our voting stock before we became a
public company in this offering, Section 203 of the DGCL by its terms is
currently not applicable to business combinations between MCSi and us even
though MCSi owns 15% or more of our outstanding stock. If any other person
acquires 15% or more of our outstanding stock, such person will be subject to
the provisions of Section 203 of the DGCL.

CERTAIN PROVISIONS OF OUR AMENDED AND RESTATED CERTIFICATE OF INCORPORATION

    Our amended and restated certificate of incorporation and amended and
restated bylaws contain provisions governing various methods and procedures to
be followed in connection with stockholder actions. These provisions include a
requirement that advance notice be delivered to Zengine of any business to be
brought by a stockholder before an annual or special meeting of stockholders and
for certain procedures to be followed by stockholders in nominating persons for
election to our board of directors. Generally, special meetings of stockholders
may only be called by our board of directors, chairman, president or holders of
35% or more of our outstanding common stock. Only such business may be conducted
at a special meeting of stockholders as is set forth in the notice for such
meeting. Stockholders may act without a meeting provided that written consents
signed by not less than the minimum number of votes that would be necessary to
authorize or take such action at a meeting at which all of the stockholders who
would be entitled to vote at a meeting called for that purpose were present and
voted.

    Our amended and restated certificate of incorporation provides that, except
as may be provided in connection with the issuance of any series of preferred
stock, the number of directors shall be fixed from time to time pursuant to a
resolution adopted by our board of directors. Our amended and restated
certificate of incorporation provides for a classified board of directors,
consisting of three classes as nearly equal in size as practicable. Each class
holds office until the third annual stockholders' meeting for election of
directors following the most recent election of such class, except that the
initial terms of the three classes expire in 2001, 2002 and 2003, respectively.
Directors may only be removed for cause on the affirmative vote of a majority of
the outstanding shares then entitled to vote. Vacancies on the board of
directors may be filled by a vote of the directors then in office.

    Application has been made for quotation of our common stock on the Nasdaq
National Market under the symbol "ZNGN."

TRANSFER AGENT AND REGISTRAR

    The transfer agent and registrar for our common stock is Registrar and

                        SHARES ELIGIBLE FOR FUTURE SALE

GENERAL

    The 4,290,000 shares of our common stock sold in this offering, or 4,875,000
shares if the underwriters exercise their over-allotment option in full, will be
freely tradable without restriction under the Securities Act, except for any
such shares which may be acquired by an "affiliate" of Zengine (an "Affiliate")
as that term is defined in Rule 144 under the Securities Act, which shares will
remain subject to the resale limitations of Rule 144.

    The 8,347,944 shares of our common stock that will continue to be held by
MCSi after this offering constitute "restricted securities" within the meaning
of Rule 144, and will be eligible for sale by MCSi in the open market on
            , 2000, subject to certain contractual lockup provisions and the
applicable requirements of Rule 144, both of which are described below. Zengine
has granted certain registration rights to MCSi. See "--Registration Rights."

    Generally, Rule 144 provides that a person who has beneficially owned
"restricted" shares for at least one year will be entitled to sell on the open
market in brokers' transactions within any three month period a number of shares
that does not exceed the greater of:

    - 1% of the then outstanding shares of common stock; and

    - the average weekly trading volume in the common stock on the open market
      during the four calendar weeks preceding such sale.

Sales under Rule 144 are also subject to certain post-sale notice requirements
and the availability of current public information about Zengine.

    In the event that any person other than MCSi who is deemed to be an
Affiliate purchases shares of our common stock pursuant to this offering or
acquires shares of our common stock pursuant to an employee benefit plan of
Zengine, the shares held by such person are required under Rule 144 to be sold
in brokers' transactions, subject to the volume limitations described above.
Shares properly sold in reliance upon Rule 144 to persons who are not Affiliates
are thereafter freely tradable without restriction.

    Sales of substantial amounts of our common stock in the open market, or the
availability of such shares for sale, could adversely affect the price of our
common stock.

    Each of Zengine, MCSi, Wilblairco Associates, At Home Corporation and the
directors and executive officers of Zengine and MCSi have agreed that, without
the prior written consent of William Blair & Company on behalf of the
underwriters, they will not, during the period ending 180 days after the date of
this prospectus, sell or otherwise dispose of any shares of our common stock,
subject to certain exceptions. William Blair will have discretion to waive
compliance of the terms of these lock-up agreements, although William Blair has
advised Zengine that, at this time, it as no present intention to waive any
compliance, has no understanding with respect to the release of any shares from
any lock-up agreement prior to their expiration and does not expect to release
any shares from the lock-up agreements. William Blair has advised Zengine that,
in considering a request to release any shares from a lock-up agreement, it
would examine the amount of shares in question, the holder of such shares, the
expected market perception from the proposed sale of such shares and the reason
the holder has requested a waiver from the lock-up agreement. See
"Underwriters."

    An aggregate of 3,484,300 shares of our common stock are reserved for
issuance under our stock option plan and employee stock purchase plan. We intend
to file a registration statement on Form S-8 covering the issuance of shares of
our common stock pursuant to these plans. Accordingly, the shares issued
pursuant to these stock option plans will be freely tradable, subject to the
restrictions on resale by Affiliates under Rule 144.

REGISTRATION RIGHTS

    We have entered into a registration rights agreement with Wilblairco, At
Home, REX Stores, MCSi and Messrs. Savarino, Dhadphale and Feaver which provides
that they may require us to register under the Securities Act all or a portion
of our common stock that they hold at any time after 180 days

                                       63
<PAGE>
after this offering, subject to certain conditions. Any shares of our common
stock sold pursuant to these registration rights would be eligible for immediate
resale in the public market without restriction by persons other than our
Affiliates. For more information regarding this registration rights agreement,
please see "Certain Transactions."

    Any sales of substantial amounts of our common stock in the public market,
or the perception that such sales might occur, whether as a result of MCSi's
registration rights or otherwise, could have a material adverse effect on the
market price of our common stock. See "Risk Factors."

                              PLAN OF DISTRIBUTION

    Of the 4,290,000 shares offered by this prospectus, 3,900,000 shares are

MCSi, our parent company and principal stockholder.

    This offering will be underwritten on a firm commitment basis. In the
underwriting agreement, the underwriters have agreed, subject to the terms and
conditions set forth therein, to purchase the shares of common stock being sold
pursuant thereto at a price per share equal to the public offering price less
the underwriting discount specified on the cover page of this prospectus.
According to the terms of the underwriting agreement, the underwriters will
either purchase all of the shares or none of them. In the event of default by
any underwriter, in certain circumstances the purchase commitments of the
non-defaulting underwriters may be increased or the underwriting agreement may
be terminated.

    The representatives of the underwriters have advised Zengine that the
underwriters will offer the shares of common stock to the public at the public
offering price specified on the cover page of this prospectus. The underwriters
may also offer the shares to dealers at the public offering price less a
concession of up to       per share. The underwriters may allow, and these
dealers may re-allow, a concession of up to       per share to certain other
dealers. The underwriters will offer the shares subject to prior sale and
subject to receipt and acceptance of the shares by the underwriters. The
underwriters may reject any order to purchase shares in whole or in part. The
underwriters expect that Zengine will deliver the shares to the underwriters
through the facilities of the Depository Trust Company in New York, New York on
or about             , 2000. At that time, the underwriters will pay Zengine for
the shares in immediately available funds. After the commencement of the initial
public offering, the representatives may change the public offering price and
the other selling terms.

    The underwriters have the option to purchase up to an aggregate of 585,000
additional shares of common stock from Zengine at the same price they are paying
for the 3,900,000 shares offered hereby in the underwritten public offering. The
underwriters may purchase additional shares only to cover over-allotments made
in connection with this offering and only within 30 days after the date of this
prospectus. If the underwriters decide to exercise this over-allotment option,
each underwriter will be

                                       64
<PAGE>
required to purchase additional shares in approximately the same proportion as
set forth in the table above. The underwriters will offer any additional shares
that they purchase on the terms described in the preceding paragraph.

    The following table summarizes the compensation to be paid by Zengine to the
underwriters:

Underwriting discount paid by Zengine...................
</TABLE>

    Zengine estimates the expenses of this offering payable by Zengine,
excluding the underwriting discount, to be $1.2 million.

    Zengine has agreed to indemnify the underwriters and their controlling
persons against specific liabilities, including liabilities under the Securities
Act.

    Zengine, its executive officers and directors, MCSi, Wilblairco and At Home
have agreed not to sell or transfer any shares of common stock, or to engage in
hedging transactions with respect to the common stock, for a period of 180 days
from the date of this prospectus without the consent of William Blair. After
giving effect to this offering, stockholders who have agreed to this lock-up
arrangement will hold an aggregate of 12,183,480 shares of common stock and
options to purchase 1,380,118 shares of common stock. For more information, see
"Shares Eligible for Future Sale."

    In connection with this offering, the underwriters and other persons
participating in this offering may engage in transactions which affect the
market price of the common stock. These may include stabilizing and
over-allotment transactions and purchases to cover syndicate short positions.
Stabilizing transactions consist of bids or purchases for the purpose of
pegging, fixing or maintaining the price of the common stock. Over-allotment
involves selling more shares of common stock in this offering than are specified
on the cover page of this prospectus, which results in a syndicate short
position. The underwriters may cover this short position by purchasing common
stock in the open market or by exercising all or part of their over-allotment
option. In addition, the representatives of the underwriters may impose a
penalty bid. This allows the representatives to reclaim the selling concession
allowed to an underwriter or selling group member if common stock sold by such
underwriter or selling group member in this offering is repurchased by the
representatives in stabilizing or syndicate short covering transactions. These
transactions, which may be effected on the Nasdaq National Market or otherwise,
may stabilize, maintain or otherwise affect the market price of the common stock
and could cause the price to be higher than it would be without these
transactions. The underwriters and other participants in this offering are not
required to engage in any of these activities and may discontinue any of these
activities at any time without notice. Neither Zengine nor any of the
underwriters makes any representation or prediction as to whether the
underwriters will engage in these transactions or choose to discontinue any
transactions engaged in or as to the direction or magnitude of any effect that
these transactions may have on the price of the common stock.

    The representatives of the underwriters have advised Zengine that the
underwriters do not intend to confirm, without client authorization, sales to
any account over which they exercise discretionary authority.

    Prior to this offering, there has been no public market for Zengine's common
stock. Consequently, Zengine and the representatives of the underwriters will
negotiate to determine the initial public offering price. They will consider
current market conditions, Zengine's operating results in recent periods, the
market capitalization of other companies in its industry and estimates of
Zengine's potential. The estimated price range specified on the cover page of
this prospectus may change because of market conditions and other factors.

    The underwriters have reserved for sale, at the initial public offering
price, up to 195,000 shares of common stock in this offering for Zengine
employees and other individuals with a relationship with Zengine. Purchases of
the reserved shares would reduce the number of shares available for sale to the

                                       65
<PAGE>
general public. The underwriters will offer any reserved shares which are not so
purchased to the general public on the same terms as the other shares.

    We have applied for listing of the common stock on the Nasdaq National
Market under the symbol "ZNGN."

    In October 1999, we sold 902,478 shares of our common stock to Wilblairco
Associates for $2.0 million. Wilblairco Associates, an Illinois general
partnership, is an affiliate of William Blair & Company, which is the lead
underwriter of this offering.

    fbr.com, a division of FBR Investment Services, Inc., which is an affiliate
of Friedman, Billings, Ramsey & Co., Inc., will be providing an Internet
distribution channel for this offering. Friedman, Billings, Ramsey & Co., Inc.
has agreed to allocate a limited number of shares to fbr.com for sale to its
online brokerage account holders. An electronic prospectus is available on the
Web site maintained by fbr.com. Other than the prospectus in electronic format,
the information on the fbr.com Web site relating to this offering is not a part
of this prospectus and should not be relied upon by prospective investors.

    E*OFFERING Corp., one of the underwriters, will allocate for distribution by
E*TRADE Securities, Inc. a portion of the shares that E*OFFERING is underwriting
in this offering. Copies of the prospectus in electronic format, from which you
can link to a "Meet the Management" presentation through an embedded hyperlink,
will be made available on Internet Web site, maintained by E*OFFERING Corp. and
E*TRADE Securities, Inc. Customers of E*TRADE Securities, Inc. who complete and
pass an online eligibility profile may place conditional offers to purchase
shares in this offering through E*TRADE's Internet Web site.

MCSi SUBSCRIPTION PROGRAM

    As part of this offering, we are offering 390,000 shares of our common stock
in the MCSi Subscription Program to stockholders of MCSi, our parent company and
principal stockholder. MCSi's stockholders may subscribe for one share of common
stock for every 30 shares of MCSi common stock held by them, and may not
transfer the opportunity to subscribe to another person except involuntarily by
operation of law. Persons who owned at least 100 shares of MCSi common stock as
of May 15, 2000 are eligible to purchase shares from us under the program.
Shareholders who own less than 100 shares of MCSi common stock will be
ineligible to participate in the MCSi Subscription Program.

    Under a standby purchase agreement, MCSi will purchase from us any of the
shares offered by us under the program that are not purchased by the
stockholders of MCSi. Distribution of share certificates purchased through the
MCSi Subscription Program will be made to the purchasers as soon as practicable
following closing of the sale of the shares to the public. It is expected that
sales under the MCSi Subscription Program will be reflected in purchasers'
book-entry accounts at the Depository Trust Company, if any, upon the closing of
these sales. After the closing of these sales, we will mail stock certificates
to all purchasers who do not maintain book-entry accounts at the Depository
Trust Company. Prior to this offering, MCSi owned 68.5% of our common stock.
After this offering, MCSi will own approximately 50.7% of our common stock,
assuming that all 390,000 shares are purchased by MCSi stockholders in the
subscription program. The purchase price under the program, whether paid by MCSi
stockholders or MCSi, will be the same price per share as set forth on the cover
page of this prospectus. All shares will be sold to stockholders of MCSi or to
MCSi. Neither MCSi nor any other underwriter will receive any compensation from
Zengine or any other person, with respect to this subscription offering,
including any underwriting discounts or commissions.

    The total proceeds before expenses to be received by Zengine from both the
underwritten public offering and the MCSi Subscription Program will be
approximately $55.0 million, assuming no exercise of the over-allotment option.

                                       66
<PAGE>
    The expenses of the MCSi Subscription Program are estimated at $25,000 and
are payable by us. The total expenses for the offering, including the expenses
associated with the underwritten public offering, are estimated at approximately
$1.2 million.

    MCSi is an underwriter with respect to the shares included in the MCSi
Subscription Program. MCSi is not an underwriter with respect to the other
shares offered by this prospectus. MCSi is not included in the term
"underwriter" as used in this prospectus. MCSi's sole condition to purchase any
shares that are not purchased by its stockholders in the MCSi Subscription
Program is that the conditions to the underwriter's obligation have been met.
This means that MCSi will be required to purchase these shares if, and only if,
the underwriters are obligated to purchase shares in the underwritten public
offering. MCSi has not participated in any discussions or negotiations with
Zengine and the underwriters regarding the initial public offering price. MCSi
will not have any right to seek indemnification from Zengine regarding its
agreement to accept underwriter liability with respect to the shares included in
the MCSi Subscription Program.

                                 LEGAL MATTERS

by Elias, Matz, Tiernan & Herrick L.L.P., Washington, D.C. Certain legal matters
in connection with this offering will be passed upon for the underwriters by

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of Zengine, Inc.

    The stock split and the change in the number of authorized shares described
in Note 2 to the financial statements has not occurred at August 21, 2000. When
it has occurred, we will be in a position to furnish the following report:

       "In our opinion, the accompanying balance sheets and the related
       statements of operations, changes in stockholders' equity and cash flows
       present fairly, in all material respects, the financial position of
       Zengine, Inc. ("Zengine"), a majority owned subsidiary of MCSi, Inc., at
       September 30, 1999 and March 31, 2000, and the results of its operations
       and its cash flows for the period from inception (January 1, 1999) to
       September 30, 1999 and the six months ended March 31, 2000 in conformity
       with accounting principles generally accepted in the United States. These
       financial statements are the responsibility of Zengine's management; our
       responsibility is to express an opinion on these financial statements
       based on our audits. We conducted our audits of these statements in
       accordance with auditing standards generally accepted in the United
       States which require that we plan and perform the audits to obtain
       reasonable assurance about whether the financial statements are free of
       material misstatement. An audit includes examining, on a test basis,
       evidence supporting the amounts and disclosures in the financial
       statements, assessing the accounting principles used and significant
       estimates made by management, and evaluating the overall financial
       statement presentation. We believe that our audits provide a reasonable
       basis for the opinion expressed above.

       As more fully described in Note 8, with respect to the financial
       statements for the five month period ended February 29, 2000, which are
       not presented separately herein, Zengine has revised its accounting for
       stock based compensation and the accretion of a put option written by its
       majority stockholder."

1. THE COMPANY

    Zengine, Inc. (the "Company") commenced operations in January 1999 as a
division of MCSi, Inc. (formerly known as Miami Computer Supply Corporation)
("MCSi") and was incorporated as BuySupply.com, Inc. ("BuySupply"), a wholly
owned subsidiary of MCSi in March 1999. BuySupply changed its name to
Zengine, Inc. in September 1999. At September 30, 1999 and March 31, 2000, MCSi
owned 83.3% and 68.5%, respectively, of the outstanding shares of the Company.
As BuySupply, the Company sold computer supplies and audio-visual equipment over
the Internet. In the Spring of 1999, the Company began to develop the Zengine
business model (described below) and implemented it throughout the Summer and
Fall of 1999, while maintaining its Internet operations. Commencing in the
Spring of 1999, the Company also devoted time to enhancing, improving and
administering dedicated Web sites for certain MCSi customers. Subsequent to
September 30, 1999, the Company focused its efforts solely on implementing the
Zengine business model, including continued work on enhancing, improving and
administering MCSi's Web sites and no longer utilizes the BuySupply model.

    The Company emerged from the development stage during the six month period
ended March 31, 2000 as it began to earn revenues from the Zengine business
model. Start-up costs incurred in the preoperating stage were expensed as
incurred. The Company has adopted a fiscal year ending September 30. These
financial statements include audited financial statements as of September 30,
1999 and for the Company's initial fiscal period of January 1, 1999 through
September 30, 1999 and audited financial statements as of March 31, 2000 and for
the six month period then ended. The unaudited financial statements as of
June 30, 2000 and for the three and nine month periods then ended have been
prepared in accordance with Rule 10-01 of SEC Regulation S-X. Consequently, the
unaudited financial statements do not include all the disclosures required under
generally accepted accounting principles for complete financial statements.
However, in the opinion of the management of the Company, the information
presented herein includes all adjustments (consisting only of normal recurring
adjustments) necessary to present fairly the financial position, results of
operations and cash flows of the Company as of June 30, 2000 and for the three
and nine month periods then ended.

    The Company provides a comprehensive suite of technology-based solutions
that enable businesses to conduct electronic commerce. The Company offers a full
range of integrated services for both business-to-business and
business-to-consumer e-commerce including Web site user interface design,
product content and merchandising, personalization and customer relationship
management, advertising and sponsorship management, order management, inventory
management and order fulfillment, end-user customer service and reporting and
analysis. The Company's solutions, delivered on an outsourced basis, allow its
clients to quickly and cost-effectively create, maintain and enhance their
e-commerce presence. These solutions allow the Company's clients to build,
manage and understand online customer relationships and to market, sell and
support products and service more effectively.

    The Company has looked to MCSi for financial and business support since its
inception. Through September 30, 1999 MCSi contributed $1,106,887 to the capital
of the Company; no capital has been contributed by MCSi since September 30,
1999. Revenues for the six month period ended March 31, 2000 include $1,309,828
of revenue from the administration of MCSi's business-to-business dedicated Web
sites under an e-commerce services agreement, which became effective October 1,
1999. These revenues represent 48.3% of the Company's total revenue for the six
month period ended March 31, 2000. The Company's current arrangement to service
the MCSi dedicated Web sites expires in October, 2001. In addition, advertising
revenue of $1,349,250, or 49.8% of total revenue, for the six month period ended
March 31, 2000 was generated primarily from OEM product advertisers who either
placed banner advertisements on clients' Web pages which the Company serves, or
purchased

preferential placement of the OEM manufacturer's products on clients' stores.
MCSi has supply arrangements with the OEM companies that purchase advertising
from the Company. Although the Company negotiated each OEM advertising
arrangement, MCSi's relationships with the OEM companies could have influenced
the Company's obtaining the advertising and the Company may not have obtained
the advertising without MCSi's relationship. The Company also conducts business
with MCSi under a distribution services agreement, administrative services
agreement and sublease and equipment leasing agreements. All of these
transactions are more fully described in Note 4.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

REVENUE RECOGNITION

    Revenues are recognized when goods are shipped or services are performed and
accepted by the customer. Revenues for the nine month period ended
September 30, 1999 represent revenues of the BuySupply business model.
Subsequent to October 1, 1999, all revenues were derived from the Zengine
business model.

    Revenues under the Zengine business model are comprised of (a) service fees,
which include integration and set-up fees, transaction fees and subscription
fees, and (b) advertising and sponsorship fees. Revenues are recognized as
follows:

    SERVICE FEES

    INTEGRATION AND SET-UP FEES

    The Company provides integration and set-up services to its clients. Under
these arrangements, services may include the development or design of a client's
Web site, migration of the client's current Web site content to the Company's
technology, integration of the client's Web site to the client's current
computer systems, or other similar activities. To the extent that these fees are
associated with a contract to provide subsequent outsourced transaction-based
services to a client, these fees are recognized ratably over the term of the
transaction services agreement. Otherwise, revenue is recognized when the
service is completed, the client has accepted the service and there is no future
obligation to provide any additional service.

    TRANSACTION FEES

    The Company provides outsourced transaction-based services to customers such
as providing product content and merchandising, invoice processing, order
management, custom fulfillment and end-user customer service on a commission
basis. Pursuant to the Company's arrangements with its first two third party
clients, commission revenue is determined as a percentage of the gross margin on
the sales value to the end customer. Under all subsequent arrangements,
commission revenue is based on a percentage of net sales value to the end
customer. Revenue from transaction fees is recognized when the service is
completed.

    SUBSCRIPTION FEES

    The Company provides subscription arrangements for maintenance and related
services for a fee. Revenue from subscription fees is recognized ratably over
the term of the subscription.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

    ADVERTISING AND SPONSORSHIP FEES

    Revenues from advertising take the form of fees when the Company sells
banner advertising or product placement advertising on Web pages served by the
Company on the Company's clients' stores. These arrangements call for continuous
advertising or product placement over a certain time period and are not
contingent upon events such as obtaining certain levels of sales, Web site
visits or other factors. Revenue is recognized ratably over the period of the
advertising/placement services based on the fulfillment of obligations under the
advertising/placement arrangement.

    SUMMARY

    Revenue for the nine month period ended September 30, 1999 and the six month
period ended March 31, 2000 is summarized as follows:

</TABLE>

PROPERTY AND EQUIPMENT

    Property and equipment primarily consists of computer technology equipment
and is stated at cost, less accumulated depreciation. Depreciation is computed
on the straight-line method over the estimated useful lives of the assets
(currently, three years for all assets). At September 30, 1999 and March 31,
2000, accumulated depreciation totaled $1,027 and $8,337, respectively.
Depreciation expense totaled $1,027 and $7,310, respectively, for the nine month
period ended September 30, 1999 and the six month period ended March 31, 2000.

SOFTWARE DEVELOPMENT COSTS

    Costs to develop the Company's software have been capitalized subsequent to
the Company determining that technological feasibility of the software had been
achieved. Software development costs are being amortized over a three year
period on a straight-line basis, subject to tests for ultimate realizability
based on future estimated revenues. At September 30, 1999 and March 31, 2000,
accumulated amortization totaled $20,464 and $93,863, respectively. Amortization
expense totaled $20,464 and $73,399, respectively, for the nine month period
ended September 30, 1999 and the six month period ended March 31, 2000. Research
and development costs which were charged against operations totaled $15,846
during the nine month period ended September 30, 1999 and nil for the six month
period ended March 31, 2000.

OTHER ASSETS

    Other assets include the Company's prepayments to a client for the
contractual right to be the sole audio visual store provider for the client.
These costs are being charged to expense on a straight-line basis over the two
year term of the related arrangement and total $450,000 ($300,000 and $150,000

other current assets and other assets, respectively) at March 31, 2000. The
remainder of the other assets relate to the Company's payment of expenses
relating to its planned initial public offering.

ADVERTISING COSTS

    The Company expenses all advertising costs as incurred.

INCOME TAXES

    Through September 30, 1999, the Company was included in the consolidated
income tax return of MCSi. The provision for income taxes is computed on a
separate company basis. The asset and liability approach is used to recognize
deferred tax assets and liabilities for the expected future tax consequences of
temporary differences between the carrying amounts of assets and liabilities for
financial reporting purposes and the tax bases of assets and liabilities. The
Company records a valuation allowance related to its deferred income tax assets
when, in the opinion of management, it is more likely than not that some portion
or all of the deferred tax assets will not be realized.

EARNINGS (LOSS) PER SHARE

    Earnings (loss) per share is computed as if the Company had been
incorporated on January 1, 1999. Basic per share amounts represent the weighted
average number of shares outstanding during the period, while diluted per share
amounts give effect to the conversion of all other convertible equity securities
(stock options and stock awards) to the extent their assumed conversion is not
anti-dilutive. For the period January 1, 1999 through September 30, 1999, the
assumed conversion of stock options (169,302) and stock awards (1,145,450) were
excluded from diluted loss per share because their assumed conversion was
anti-dilutive.

    The following table summarizes the shares included in the basic and diluted
loss per share calculations.

    On September 29, 1999, the Company enacted a 10-for-1 stock split;
additionally, the Company intends to effect a 6.7686-for-1 stock split (the
"stock splits") and increase its authorized number of common shares prior to an
initial public offering of its common stock. All share and per share amounts
presented in the financial statements give retroactive treatment to the stock
splits as if they had occurred on January 1, 1999.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

COMPREHENSIVE INCOME (LOSS)

    The Company has no components of other comprehensive income; accordingly,
net loss and comprehensive loss are the same.

CONCENTRATIONS OF CREDIT RISK

    The Company's operations are presently conducted in the United States. While
the Company intends to expand the scope of its operations internationally, no
such activity had occurred through March 31, 2000. At March 31, 2000, accounts
receivables totaled $1,344,621. Based on management's assessment, accounts
receivable are collectible in full, and no allowance for uncollectible accounts
is considered necessary. Accounts receivable are recorded net of amounts owed to
the Company's clients as the right of offset of gross receivables and payables
exists between the parties. Management monitors its credit risks using policies
it considers appropriate in the circumstances.

FAIR VALUES AND DERIVATIVE TRANSACTIONS

    The Company believes that the fair value of its monetary assets and
liabilities approximates the carrying value in these financial instruments. The
Company does not engage in derivative transactions.

STOCK COMPENSATION

    The Company measures compensation expense for its stock-based employee
compensation plans using the intrinsic value method and has provided in Note 7
the pro forma disclosures of the effect on net income (loss) and earnings (loss)
per common share as if the fair value-based method had been applied in measuring
compensation expense.

RECENT ACCOUNTING PRONOUNCEMENTS

    The Company is not aware of any pending accounting pronouncements that it
believes will have a material impact on the Company's financial position,
results of operations or cash flows, including the provisions of Staff
Accounting Bulletin 101, which was recently issued by the Securities and
Exchange Commission.

USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the periods.
Actual results could differ from these estimates.

3. EQUITY TRANSACTIONS

    In October 1999, the Company sold to one of its clients and an unrelated
investor (the "investors") 1,804,956 shares of common stock of the Company at a
price of $2.22 per share for total gross proceeds of $4 million (net proceeds,
after offering costs, were $3,871,049). MCSi cancelled 2,481,816 shares of the
Company it owned to facilitate this transaction. As described in Note 4, the
proceeds from this sale were forwarded to MCSi pending future use by Zengine and
is recorded as a component of the amounts receivable from MCSi.

                                 ZENGINE, INC.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

    In connection with the transaction described in the preceding paragraph, the
Company paid $600,000 to the client for the contractual right to be the sole
audio visual store provider to the client. The amount was capitalized as other
assets and is being charged to expense on a straight-line basis over the term of
the arrangement. In addition, the Company has committed to purchase $3,400,000
of advertising services over 24 months beginning in December 1999 from one of
the investors in monthly installments of $141,667. The Company is recognizing
the expense associated with this advertising program as the advertising services
are provided on a straight-line basis over the term of the agreement.

    In conjunction with an e-commerce services agreement entered into with one
of the Company's clients in January 2000, the Company and the client agreed that
the client would be granted a warrant to purchase the Company shares if the
Company completes an initial public offering ("IPO"). If granted, the warrant
will entitle the client to purchase 1.7% of outstanding shares of the Company
subsequent to the IPO, at the IPO price. The warrant would be exercisable for a
three year period, commencing on the date of grant. Since the issuance of this
warrant is based upon uncertain future events, these financial statements do not
reflect any accounting relative to this warrant.

4. RELATED PARTY TRANSACTIONS

    Effective October 1, 1999, the Company entered into an e-commerce services
agreement with MCSi for a two year period. Under the terms of the e-commerce
agreement, the Company receives a commission equal to 10% of retail value of
products sold to those customers of MCSi provided with dedicated customer Web
sites ("Web sites") in exchange for the Company designing, enhancing and
providing certain support services for these Web sites.

    Additionally, effective October 1, 1999, the Company entered into three
other agreements with MCSi; these are (a) a distribution services agreement
whereby the Company will pay MCSi a fee of three percent of the retail value of
the goods sold to or through third party clients for which MCSi performs the
fulfillment and distribution function, (b) an administrative services agreement
whereby the Company will be charged $720,000 per year in reimbursement for
treasury and cash management services, accounting services, corporate
development services, risk management and administrative insurance services,
benefit plan design services, human resources and compensation services, Web
site population services and advertising sales services costs which MCSi incurs
for the Company's benefit, and (c) a leasing agreement whereby the Company will
pay MCSi $125,000 per year to lease corporate offices and $25,000 per year to
lease certain personal property. These agreements between the Company and MCSi
have a two year term, except for the leasing agreement, which expires on May 1,
2001. In June 2000, the distribution services agreement was amended to provide
for a fee payable by the Company to MCSi equal to a percentage of MCSi's gross
expenses relating to the operation of MCSi's warehouse. This agreement expires
on October 1, 2001. The terms of the arrangements with MCSi do not necessarily
represent those which would be obtained in an arm's-length transaction with an
unrelated party.

    Using the proceeds from the sale of stock described in Note 3, in October,
1999, the Company and MCSi entered into a demand note arrangement ("Demand
Note"), whereby the Company loaned $3,871,049 to MCSi. The demand note is
payable on demand and accrues interest quarterly at the Merrill Lynch Ready
Asset Trust rate (5.65% at March 31, 2000).

    In December 1999, MCSi purchased advertising of $47,000 from the Company. In
addition, advertising revenue of $1,302,250 for the six months ended March 31,
2000 was generated primarily from OEM product advertisers who either placed
banner advertisements on clients' Web pages which the Company serves, or
purchased preferential placement of the OEM manufacturer's products on clients'
stores. MCSi has supply arrangements with the OEM companies that purchase
advertising from the Company. Although the Company negotiated each OEM
advertising arrangement, MCSi's relationships with the OEM companies could have
influenced the Company's obtaining the advertising and the Company may not have
obtained the advertising without MCSi's relationship.

    With respect to all of its transactions with MCSi, the Company and MCSi have
agreed to a monthly "net" settlement. The following table summarizes the net
receivable due from MCSi related to the aforementioned agreements as of
March 31, 2000:

    Amounts payable arising from current account activity include trade accounts
payable and other expenses of the Company which are being paid by MCSi on the
Company's behalf. Accordingly, no separate trade accounts payable are included
on the accompanying balance sheet.

    As a result of entering into the leasing agreement with MCSi, the Company is
committed to the following minimum lease payments for the periods presented
below:

<TABLE>

    Through September 30, 1999 the Company looked to MCSi for many of the
services it currently receives under the administrative services agreement
entered into effective October 1, 1999. These included administrative services
such as treasury, payroll, accounting and financial support functions. The
financial statements for the nine month period ended September 30, 1999 include
charges for these services from MCSi totalling $435,623 and have been allocated
from MCSi to the Company based upon the ratio of the number of the Company's
employees to the total number of MCSi employees. Management believes this basis
is reasonable in the circumstances. As the Company has looked to MCSi for these
administrative services since its inception, and will rely on MCSi for these
services for the foreseeable future, it is not practical to estimate the costs
the Company would have incurred had it obtained these services from unrelated
parties.

    Through September 30, 1999 MCSi had contributed to the Company, as capital,
all of the financial support it had provided rather than loaning funds to the
Company. The following table summarizes the interest free financial support that
MCSi provided to the Company on a monthly basis from January 1999 through
September 30, 1999 that has been recorded as additional paid in capital:

    Prior to entering into the leasing agreement effective October 1, 1999, the
Company operated from premises leased to it, on a month to month basis, by MCSi.
During the period ended September 30, 1999, MCSi charged the Company $77,497 for
rental of these facilities.

    The employees of the Company are permitted to participate in MCSi's defined
contribution pension plan. This plan covers substantially all employees who meet
certain eligibility requirements and the Company's expense related thereto
comprises matches to employee contributions to the Plan, limited to a percent of
the employees' compensation. Expenses under the plan were nil and $3,999,
respectively, for the nine month period ended September 30, 1999 and the six
month period ended March 31, 2000.

5. INCOME TAXES

    From January 1, 1999 through March 31, 2000 the Company paid no income taxes
and had no current provision for income taxes due to its operating losses since
inception. The components of the provision for income taxes follows:

    Startup costs above relate to selling, general and administrative costs
which the Company incurred in its development stage and were expensed in the
Company's statement of operations, but must be capitalized and amortized to
expense over a five year period for income tax purposes. The Company began
amortizing these costs for tax purposes as it generated revenue from its planned
business activities during the six month period ended March 31, 2000.

    The Company has provided a valuation allowance against its net deferred tax
assets because management, at the present time, is of the view that it is more
likely than not that these assets will not be realized. The Company's effective
tax rate differs from the expected statutory rate by virtue of the inability to
currently deduct net operating losses and the valuation allowance described
above. The Company's net operating losses of $348,200 and $576,971 at
September 30, 1999 and March 31, 2000, respectively, are subject to carryfoward
provisions which expire from 2014 through 2015.

7. STOCK COMPENSATION AND RELATED MATTERS

    In March 1999, the Company agreed to issue to three key executives a total
of 2,030,580 shares of common stock. While the Company agreed to issue the
shares in March 1999, the actual grant did not occur until September 1999. These
stock awards vest one third commencing on the date of issue and ratably
thereafter, on a quarterly basis, through June 30, 2002. Based on an independent
appraisal of the fair value of the shares granted, the Company will recognize
compensation expense of $180,000 over the vesting period, of which $78,462 was
recognized during the nine month period ended September 30, 1999 and $18,462 was
recognized during the six month period ended March 31, 2000.

    In August 1999, the Board of Directors formally adopted the Zengine 1999
Stock Option Plan (the "Plan") which had been in effect since March 1999. The
Plan provides that up to 1,353,720 options to purchase common stock of the
Company may be granted to employees and others. Although, options may be granted
with exercise prices equivalent to the estimated fair value of the stock on the
grant date, the options granted through May 2000, were granted at exercise
prices less than the estimated fair value of the shares on the grant date. The
grants with exercise prices less than the fair market value of the stock will
result in aggregate compensation charges over the vesting period of $2,195,314
and resulted in compensation charges of $11,021 and $94,711 for the nine month
period ended September 30, 1999, and the six month period ended March 31, 2000
respectively. Vesting occurs ratably over a four-year period, although two
grants totaling 812,232 options vested on the date of grant. All options expire,
if not exercised, ten years from the date of grant. At March 31, 2000, 14,214
options remain which could be granted under the Plan.

    The following table summarizes activity in the stock option plan in number
of shares:

8. OTHER MATTERS

    During May 2000 the Company filed an initial registration statement with the
Securities and Exchange Commission covering the initial public offering of the
common stock of the Company. That registration statement included financial
statements of the Company for the period from inception (January 1, 1999)
through September 30, 1999 and for the five-month period ended February 29,
2000. Although not presented herein, the financial statements for the five month
period ended February 29, 2000 have been revised to reflect adjustments with
respect to (a) stock based compensation, described in Note 7 and (b) the
accounting for a put option written by MCSi on the Company's common stock
arising from an October 1999 sale of the Company's common stock to two, third
party investors, described in Note 3. These adjustments did not have any impact
on the financial statements of the Company for the period from inception
(January 1, 1999) through September 30, 1999. With respect to the financial
statements for the five-month period ended February 29, 2000, the Company (a)
increased the amount of stock based compensation recorded in the financial
statements for the five month period

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

ended February 29, 2000 and (b) reversed a previously recorded charge against
income relating to a put option written by MCSi on the Company's common stock.
Both of these adjustments impact results of operations but do not have any
impact on the Company's cash flows from operating, financing or investing
activities.

    The following table summarizes the impact of these adjustments on the
financial statements of the Company for the five months ended February 29, 2000,
previously included in the initial registration statement, and not presented
separately herein:

    In addition, unearned stock based compensation of $89,829 previously
reported increased to $1,309,208 for the five months ended February 29, 2000 as
a result of this revision.


    These adjustments are already reflected in the Company's financial
statements for the six month period ended June 30, 2000; thus, no adjustments to
these financial statements are required.

    Script: (Joseph Savarino) Welcome to the "Meet the Management" Presentation
for Zengine. I'm Joseph Savarino, President and Chief Executive Officer. I would
like to introduce Louis Lipinski, Chief Financial Officer and Treasurer. We
would like to talk to you about Zengine, a provider of a comprehensive suite of
technology-based solutions that enable businesses to conduct electronic
commerce. We offer a full range of integrated services for both
business-to-business, or B2B, and business-to-consumer, or B2C, e-commerce
including Web site user interface design, product content and merchandising,
personalization and customer relationship management, advertising and
sponsorship management, order management, inventory management and order
fulfillment, end-user customer service and reporting and analysis.

"Challenges Presented by E-Commerce."

    Script: (Joseph Savarino) (see "Business--Industry Background"). Widespread
acceptance of the Internet has opened numerous opportunities for companies
seeking growth and increased efficiencies through B2B and B2C e-commerce. The
Gartner Group estimates that B2B e-commerce will grow from $145 billion in 1999
to $3.9 trillion in 2003, and B2C e-commerce will increase from $31 billion in
1999 to $381 billion in 2003, representing five-year compound annual growth
rates of 128% and 87%, respectively. As a result of this growth, an increasing
number of businesses engage e-commerce service providers to design and implement
e-commerce solutions. Although no figures are yet available on the size of the
full-service e-commerce outsourcing market, traditional e-commerce outsourcing,
usually defined as Web site design, strategy consulting, and software creation
and hosting, was a $4.6 billion industry in 1998 and is expected to grow to
$39 billion by 2002 according to IDC, representing a compound growth rate of
53%. As customer and supplier expectations increase as a result of industry
advancement, companies are forced to take advantage of and develop more
sophisticated Internet applications. Currently, few companies offer the full
range of integrated, comprehensive e-commerce services necessary for clients to
fully capitalize on their e-commerce potential. Most companies offering
outsourced solutions focus on one or just a few specific services, requiring
companies to piece together, or find a third party to integrate, these disparate
solutions. Further, speed, accuracy and customer experience are essential in the
emerging digital economy. Long implementation lead times in the development and
integration of e-commerce solutions offer faster and more efficient competitors
market advantages. Most businesses cannot afford to divert internal personnel
from their core competencies, while it becomes increasingly difficult to obtain
and retain highly skilled in-house personnel to implement these advanced
solutions.

improvements".

    Script: (Joseph Savarino) (see "Business--The Zengine Solution"): Zengine
addresses the challenges presented by e-commerce by providing a comprehensive
suite of technology-based solutions that enable our clients to quickly and
cost-effectively create, maintain and enhance their e-commerce presence on an
outsourced basis.

    Our services enable our clients to quickly establish a fully functional
e-commerce environment. Our KORE Engine eliminates the need for months of custom
programming and reduces the time needed to integrate the e-commerce application
with the client's existing computer systems. As a result, our clients are able
to drastically reduce their time-to-market. To date, we have enabled our clients
to conduct e-commerce within an average of 40 days after the commencement of our
services compared to industry ranges of several months to over one year.

    Our technology and infrastructure provide us with the ability to design and
operate a client's e-commerce Web site that is: consistent with the look, feel
and functionality of our client's existing Web site and brand strategy;
engaging, intuitive, attractive and easy to use by the Web site visitor; fast
and reliable; highly personalized; able to modify and define the client's
services in real time; secured by state-of-the-art procedures that enable
execution of transactions involving confidential personal and financial data;
and completely integrated with business systems and customer service.

    Our clients are able to obtain the benefits of e-commerce without making
significant time and financial investments in hardware, software, technical and
customer service personnel. We generally provide our solutions from our own
premises without interfering with our client's daily operations. This permits
our clients to focus on their core competencies and to leverage our knowledge,
technology and infrastructure.

    We engage in personalized customer relationship management by attempting to
optimize each customer visit to our clients' Web sites through the use of real
time interactive marketing and by attempting to resolve customer inquiries and
complaints as promptly as possible. By gathering real time information, we are
able to provide product suggestions, advertisements, incentives and promotions
that are likely to be of interest to the visitor. We believe that this
personalization of the shopping experience results in a higher user conversion
ratio, increased purchases per visit, increased purchase size and greater
customer loyalty.

    We are engaged in a constant process of technological enhancement of our
services. These improvements include the upgrade of our KORE Engine, new
merchandising features and advanced browser-based tools. The architecture of
KORE is designed to automatically and without interruption distribute our
service improvements to our clients without the need to hire consultants, bring
the system offline, or install any client-side software. Upon completion, the
feature or tool can be made available to other Zengine clients without added
development time or costs. Development under the KORE framework contrasts with
other e-commerce solutions that provide maintenance and upgrades to custom
features on an individual and typically labor intensive basis.

"Extend the capabilities of our KORE Engine", "Leverage client base", "Expand
our strategic alliances", "Assist our clients in increasing their revenues using
our state-of-the-art e-commerce solutions".

    Script: (Joseph Savarino) (see "Business--Strategy"): Our objective is to
capitalize on our proprietary technology and infrastructure, the KORE Engine, to
become the leading provider of comprehensive e-commerce enabling services. To
accomplish this goal, we are pursuing a strategy built on the following
initiatives:

    We target our sales and marketing efforts on companies that are focused on
establishing or improving their ability to conduct e-commerce yet lack the
technical expertise necessary to build and implement desired Internet
functionality. These may include original equipment manufacturers, wholesalers,
distributors and other businesses that create customized vendor and supply chain
relationships, bricks and mortar retailers, pure online retailers and Web sites
with a large and loyal user base (including portals, pure content sites,
communities, directories and service providers).

    We intend to extend the capabilities of our KORE Engine through continued
investment in its development to provide for additional functionality, extending
our use of artificial intelligence, and for vertical applications complementary
to our current offerings. We intend to develop additional capabilities through
continued internal development and, potentially, through the licensing or
acquisition of complementary technologies.

    One of the distinguishing characteristics of the Zengine business model is
the constant level of interaction that Zengine maintains with its clients.
Zengine will continue to leverage its network of clients by providing additional
services or providing access to its client network. These opportunities may
include additional products or services for Zengine to deliver to its network of
clients such as relevant content, or may include other opportunities to generate
revenue through selling access to its network of clients to outside sponsors or
providers.

    We currently have strategic business alliances with Excite@Home, United
Stationers Supply Co. and MSCi. We plan to continue to develop technology and
marketing relationships through strategic alliances with software and systems
integrators, consulting firms, advertising firms and other professional services
firms. These alliances are intended to complement our direct sales force by
providing business leads, increasing our geographic coverage and addressing new
industry segments. We also intend to leverage these relationships to commence
international sales in countries with high Internet penetration and growth
rates.

    We intend to enhance the tools our clients use to increase their user to
buyer conversion rates, increase the number of products per purchase and the
average value of each purchase. Primary tools used in achieving this goal
include, increasing the efficiency of our personalization technology and
merchandising features, such as development of more robust, real time predictive
models.

    Script: (Joseph Savarino) (see "Business--Zengine Services and Tools"): Our
business service enables original equipment manufacturers, wholesalers and
distributors to conduct personalized supply-chain management and customer
transactions over the Inernet or secure extranets enabled by Zengine. Our
consumer service enables original equipment manufacturers, bricks and mortar
retailers, online-only retailers and Web sites with a large and loyal user base,
to extend their current business over the Internet. Our services include: Web
site user interface design and product content; Merchandising; Advertising and
sponsorship management; Order management; Inventory management and order
fulfillment and End-user customer service.

    Our e-commerce services are customized and maintained using Internet-based
tools accessible by our personnel and by our clients. These tools, called KIT
(KORE Interactive Tool), are accessible through standard Web browser interfaces.
KIT provides a set of building blocks comprised of customizable components,
application templates and rule sets. These tools are instrumental in building,
rapidly accessing and easily maintaining the Zengine turn-key e-commerce
services. Our tools include: Zengine Reporting and Analysis; Zengine Content
Management; Zengine Design Center and Zengine Utility Center.

    Visual Text:  Title: "Technology". Subhead: "Key Technology Components:". In
gear image bullets, "The KORE Engine", "KORE Personalization", "Network
Architecture", "Open Source Movement".

    Script: (Joseph Savarino) (see "Business--Technology and Infrastructure"):
Our technology is based on the following four key components. Our proprietary
technology and infrastructure, the KORE Engine, enables us to build, deliver and
manage e-commerce solutions in less time and more cost effectively than existing
alternatives. The functional components of KORE are stored on a centralized
server array which services all of our e-commerce clients. This architecture
minimizes development costs and reduces time to market because we are able to
leverage existing functionality previously developed within KORE rather than
re-engineering the functionality for each application. Development within the
KORE framework significantly differs from other e-commerce solutions that
provide maintenance and upgrades to custom features on an individual and
possibly labor intensive basis.

    KORE resides on a secure, private fault-tolerant network architecture that
provides highly reliable service. This is accomplished by distributing Internet
traffic across an array of servers that are scalable and redundant. Because of
this distributed model, rapid increases in server load can be quickly scaled by
allocating more servers to immediately accommodate client Web site demand. In
addition, our redundant network architecture allows for unpredictable hardware
failure with little effect to service because the failure merely results in the
balanced distribution of server load across the server array.

    In order to maximize both personalization and speed of service, we choose to
adhere to open source standards and scalable programming languages. Development
within KORE is done in Perl5, a widely accepted standard programming language
for developing object oriented software that is the informed choice for building
large-scale e-commerce platforms that require ongoing and rapid development and
high-speed dynamically-generated Web site operations. MySQL, an open source
database, is optimized for speed and scalability and serves as the foundation
for KORE's personalized capabilities. KORE creates multiple database connections
for multiple actions both efficiently and quickly, resulting in high-speed
dynamic Web site delivery.

    Visual Text:  Title: "Competition". Subhead: "Primary Source of
Competition:". In gear image bullets, "Companies who develop their own
e-commerce system", "Internet consulting companies".

    Script: (Joseph Savarino) (see "Business--Competition"): The market for our
services is intensely competitive and subject to rapid technological change. We
expect competition to intensify in the future. Our primary source of competition
comes from companies who develop their own custom e-commerce systems or purchase
software packages and hire consultants to implement these solutions. Because
these companies have likely made significant initial investments to develop
their custom systems, they may be less likely to employ outsourced transaction
processing strategies. We also face competition from companies such as Art
Technology Group, Breakaway Solutions, Broadvision, E.piphany, Net Perceptions
and USinternetworking. In addition, other companies may enter the market to
provide similar services. We compete on the basis of certain factors, including:
technology; time-to-market; breadth of service features and functionality; ease
of implementation; speed, accessibility and ease of use; brand recognition;
price; system reliability and capacity; and customer support. We believe that we
presently compete favorably with respect to each of these factors. However, the
market for our services is still rapidly evolving, and we may not be able to
compete successfully against current and potential competitors.

    And with that, I will turn it over to Louis Lipinski for an overview of our
financial results. Louis. . .

    Script: (Louis Lipinski) (See "Management's Discussion and Analysis of
Financial Condition and Results of Operations"): Thanks, Joe. We were formed as
a division of MCSi in January 1999 to sell computer and audio-visual products,
primarily to the small office/home office market. We were subsequently
incorporated as a wholly owned subsidiary of MCSi in March 1999. Also in
March 1999, we hired three key executives, Mr. Joseph Savarino, Mr. Lalit
Dhadphale and Mr. Christopher Feaver, to revise our business concept beyond the
sale of computer and audio-visual products to the Zengine business model of
providing a full range of e-commerce services to the B2B and B2C markets. We
entered into our first third party client contract using the Zengine business
model in September 1999, and we legally changed our corporate name to
Zengine, Inc. in the Fall of 1999, after doing business as Zengine since
March 1999.

    In performing our services under the Zengine business model, we enter into
contractual arrangements with our clients that describe the services we will
perform. We generate revenues through a combination of one or more of the
following: initial set-up and integration fees, subscription fees, transaction
fees and advertising and sponsorships fees.

    We provide integration and set-up services to our clients. Under these
arrangements, our services may include the development or design of a client's
Web site, migration of the client's current Web site content to our technology,
integration of the client's Web site to the client's current computer systems or
other similar activities. To the extent that these fees are associated with a
contract to provide subsequent outsourced transaction-based services to a
client, these fees are recognized ratably over the term of the transaction
services agreement. Otherwise, revenue is recognized when the service is
completed, the client has accepted the service and we have no future obligation
to provide any additional services. Our subscription arrangements provide for
maintenance and related services over a specified time for a fee. Revenue from
subscription fees is recognized ratably over the term of the subscription. We
provide outsourced transaction-based services to customers, such as providing
product content and merchandising, transaction processing, order management,
custom fulfillment and end-user customer service. Revenues from transaction fees
are generally in the form of a commission. Under our first two arrangements with
third-party clients, our revenue is determined as a percentage of the gross
margin on revenues. Under all other arrangements entered into between our
clients and us, our revenue is based on a percentage of net revenues. Revenue
from transaction fees is recognized when the service is completed. Revenues from
advertising take the form of fees when we sell banner advertising, product
placement or other forms of advertising on Web pages we service on our clients'
stores. These arrangements call for continuous advertising or product placement
over a certain time period and are not contingent upon events such as obtaining
certain levels of sales, Web site visits or other factors. Revenue is recognized
ratably over the period of the advertising or product placement services based
on the fulfillment of obligations under the advertising or product placement
arrangements.

    Script: (Louis Lipinski) (See "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and see "Risk Factors--Risks
Related to Our Business"): During September 1999, we signed our first client
contract under the Zengine business model, and we began earning revenue from
this contract in October 1999. Accordingly, our historic financial results prior
to October 1, 1999 are not representative of our current business model. We have
not presented amounts for the six month period ended March 31, 1999 as we were
not in existence for that period and were not operating under our current
business model. Accordingly, prior period amounts from our inception
(January 1, 1999) to March 31, 1999 are not meaningful or comparable.

June 30, 2000, we had 12 e-commerce clients. Service fee revenue from the MCSi
dedicated Web sites was $2,408,121 for the nine months ended June 30, 2000,
which was 47.1% of our total revenue for the period. Our current arrangement to
service the MCSi dedicated Web sites expires on October 1, 2001. In addition, we
had advertising revenue of $2,336,750, or 45.8% of total revenue, which was
primarily derived from OEM product advertisers who either placed banner
advertisements on a client's Web pages which we serve, or purchased preferential
placement of the OEM manufacturers products on a client's stores. MCSi has
supply arrangements with the OEM companies that purchase advertising from us. We
have provided advertising or sponsorship services to 14 clients as of June 30,
2000. Although we negotiate each OEM advertising arrangement, MCSi's
relationship with the OEM companies could have influenced our obtaining the
advertising and we may not have obtained the advertising without MCSi's
relationship.

    Our revenue for the three months ended June 30, 2000 totaled $2,393,370.
Service fee revenue from the MCSi dedicated Web sites was $1,098,293 for the
three months ended June 30, 2000, which was 45.9% of our total revenue for the
period. In addition, we had advertising revenue of $987,500 or 41.3% of total
revenue, which was primarily derived from OEM product advertisers who either
placed banner advertisements on a client's Web pages which we serve, or
purchased preferential placement of the OEM manufacturers products on a client's
store.

    Our revenue for the six months ended March 31, 2000 totaled $2,710,916.
During the six months ended March 31, 2000, we initiated our Zengine service
offerings and began servicing e-commerce clients. At March 31, 2000 we had seven
e-commerce clients.

    Service fee revenue from the MCSi dedicated Web sites was $1,309,828 for the
six months ended March 31, 2000, which was 48.3% of our total revenue for the
period. In addition, we had advertising revenue of $1,349,250, or 49.8% of total
revenue, which was primarily derived from OEM product advertisers who either
placed banner advertisements on client's Web pages which we serve, or purchased
preferential placement of the OEM manufacturers products on client's stores.

    From the date of our inception to September 30, 1999, our revenues totaled
$4,089. These revenues arose from the sale of computer supply and audio-visual
products to consumers under our previous business model.

    Our cost of revenue includes the amortization of capitalized computer
software costs, the costs of our employees to perform integration and other
services and the three percent fee we pay to MCSi under the distribution
services agreement, which expires on October 1, 2001. As a percentage of our
revenues, gross margin was 88.2% for the nine months ended June 30, 2000, 88.7%
for the three months ended June 30, 2000, and 87.7% for the six months ended
March 31, 2000, all under our business model. These percentages fluctuate
depending primarily on the timing as to when we add additional employees to
perform integration and other services.

    Our costs of revenues were $23,511 for the period ended September 30, 1999
and reflects costs we incurred for the products we sold arising from the
activities of our previous business model and the amortization of capitalized
computer software costs.

    Selling, general and administrative expenses for the periods presented,
along with these amounts stated as a percentage of our revenues during the
periods we operated under the Zengine business model, is shown below:

Nine months ended June 30, 2000..........................  $4,700,646     92.1%

Six months ended March 31, 2000..........................  $2,286,845     84.4%
</TABLE>

    Changes in selling, general and administrative expenses are also influenced
as to the timing of when we add additional personnel to support these functions.
Our Selling, general and administrative costs during the nine months and three
months ended June 30, 2000 was also impacted by an amendment to our distribution
services agreement with MCSi which totalled $326,751.

    Our selling, general and administrative expenses for the nine months ended
September 30, 1999 were $914,201 and relate primarily to costs incurred to
develop the Zengine business model. The more significant selling, general and
administrative expenses relate to payroll and accounting processing costs,
salaries and rent.

    We did not provide for any income taxes because we have prepared our
provision for income taxes as if we were a separate entity. We do not owe any
income taxes because we have incurred operating losses since our inception, and
we did not record any deferred tax benefits relating to these operating losses
or any other deferred tax benefits because we presently believe it is more
likely than not that they will not be realized.

    We incurred net losses of $934,000 for the period from inception to
(January 1, 1999) to September 30, 1999, and net losses of $76,000 for the nine
months ended June 30, 2000. We anticipate that we will substantially increase
our sales and marketing, technology and infrastructure, software and development
and general and administrative expenses in fiscal 2000 and, as a result, we
expect to incur additional losses for the foreseeable future.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    Zengine is incorporated under the laws of the State of Delaware.
Section 145 ("Section 145") of the General Corporation Law of the State of
Delaware (the "General Corporation Law") provides that a Delaware corporation
may indemnify any persons who were, are or are threatened to be made, parties to
any threatened pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of such corporation), by reason of the fact that such person is or was an
officer, director, employee or agent of such corporation, or is or was serving
at the request of such corporation as a director, officer, employee or agent of
another corporation or enterprise. The indemnity may include expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit or
proceeding, provided such person acted in good faith and in a manner he
reasonably believed to be in or not opposed to the corporation's best interests
and, with respect to any criminal action or proceeding, had no reasonable cause
to believe that his conduct was illegal.

    Section 145 further authorizes a corporation to purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent 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 enterprise,
against any liability asserted against him and incurred by him in any such
capacity, arising out of his status as such, whether or not the corporation
would otherwise have the power to indemnify him under Section 145.

    Zengine's amended and restated certificate of incorporation and amended and
restated bylaws provide for the indemnification of officers and directors to the
fullest extent permitted by the General Corporation Law.

    Zengine anticipates that all of its directors and officers will be covered
by insurance policies against certain liabilities for actions taken in their
capacities as such, including liabilities under the Securities Act of 1933, as
amended.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

    Since the Registrant's incorporation on March 2, 1999, it has issued
unregistered securities to a limited number of persons as described below:

    (1) In connection with its incorporation, the Registrant issued 67,686
       shares of common stock to MCSi for an aggregate of $1,000, and other
       non-monetary consideration.

    (2) On September 14, 1999, the Registrant issued 676,860 shares of common
       stock to each of Joseph M. Savarino, Lalit P. Dhadphale and Christopher
       Feaver, pursuant to employment agreements entered into between the
       recipients and the Registrant in March, 1999 and 10,762,074 shares to
       MCSi for non-monetary consideration, 2,481,816 of which shares were
       surrendered back to the Registrant on September 29, 1999.

    (3) On October 1, 1999, the Registrant sold 902,478 shares of common stock
       to Wilblairco Associates for $2.0 million.

    (4) On October 1, 1999, the Registrant sold 902,478 shares of common stock
       to At Home Corporation for $2.0 million.

    (5) On January 21, 2000, in connection with the transactions contemplated by
       a software services agreement with rexstores.com, Inc. and REX Stores
       Corporation, the Registrant agreed to issue a warrant to REX Stores
       Corporation to purchase the number of shares of common stock that is
       equal to 1.7 percent of the number of shares outstanding on the day
       immediately following the date on which this offering is completed (not
       including the underwriters' overallotment option). The per share exercise
       price of the warrant equals the initial public per share offering price
       of this offering.

    On September 29, 1999, the Registrant effected a 10-for-1 split of its
common stock. In addition, the Registrant intends to effect a 6.7686-for-1 split
of its common stock prior to consummation of the offering. The number of shares
described in this Item 15 reflects such stock splits.

    The Registrant believes that all of the above issuances were exempt from
registration under Section 4(2) of the Securities Act as transactions not
involving any public offering.

    (b) Financial Statement Schedules

    Schedules have been omitted because the information required to be set forth
therein is not applicable, is immaterial or is shown in the financial statements
included in the prospectus.

ITEM 17. UNDERTAKINGS

    The undersigned Registrant hereby undertakes to provide to the underwriters
at the closing specified in the underwriting agreement, certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.

    Insofar as the indemnification for liabilities arising under the Securities
Act of 1933 may be permitted as to directors, officers and controlling persons
of the Registrant pursuant to the provisions described in Item 14, or otherwise,
the Registrant has been advised that in the opinion of the SEC, 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 payments by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

    The undersigned Registrant hereby undertakes that:

        (1) for purposes of determining any liability under the Securities Act,
