INFORMATION CONCERNING THE BOARD OF DIRECTORS AND ITS COMMITTEES

     The business of the Company is under the general management of the Board of
Directors as provided by the laws of Delaware and the Bylaws of the Company.
During the fiscal year ended December 31, 1998, the Board of Directors held four
formal meetings, excluding actions by unanimous written consent. Each Member of
the Board attended at least 75% of the fiscal 1998 meetings of Board of
Directors and Board committees of which he was a member.

     The Board of Directors has an Audit Committee, a Compensation Committee and
a Nominating Committee. The Audit Committee currently consists of Messrs.
Wallman and Kimberly. During 1998, the Audit Committee held four formal
meetings, excluding actions by unanimous written consent. The Audit Committee
reviews the results and scope of the audit and other services provided by the
Company's independent auditors. The Compensation Committee currently consists of
Messrs. deCastro and Fingerhut. During 1998, the Compensation Committee held no
formal meetings, instead taking action exclusively by unanimous written consent.
The Compensation Committee makes recommendations to the Board of Directors
regarding salaries and incentive compensation for officers of the Company, and
determines the amount and type of equity incentives granted to participants in
the Company's 1996 Stock Plan. The Nominating Committee currently consists of
Messrs. Kannan and Fingerhut. The Nominating Committee makes recommendations to
the Board regarding the slate of directors to be nominated for election at the
Company's annual meetings of stockholders.

VOTE REQUIRED

     The seven nominees receiving the highest number of affirmative votes of the
shares present or represented and entitled to be voted at the Meeting shall be
elected as directors of the Company. Votes withheld from any director will be
counted for purposes of determining the presence or absence of a quorum for the
transaction of business, but have no other effect under Delaware law. However,
because directors are elected by a plurality

                                        3
<PAGE>   6

vote, abstentions in the election of directors have no effect once a quorum
exists. Furthermore, shares represented by proxies returned by a broker holding
such shares in nominee or "street" name will be counted as present or
represented for purposes of determining the presence or absence of a quorum for
the transaction of business, even if such shares are not voted in matters where
discretionary voting by the broker is not allowed ("broker non-votes"). Withheld
votes and broker non-votes, if any, are not treated as votes cast and therefore,
will have no effect on the proposal to elect directors.

     THE BOARD OF DIRECTORS HAS APPROVED AND RECOMMENDS THAT STOCKHOLDERS VOTE
"FOR" THE ELECTION OF THE MANAGEMENT NOMINEES LISTED ABOVE.

         PROPOSAL NO. 2 -- APPROVAL OF AMENDMENT AND RESTATEMENT OF THE
           CERTIFICATE OF INCORPORATION TO CHANGE THE COMPANY'S NAME

     On May 19, 1999, the Board authorized an amendment to the Company's
Certificate of Incorporation (the "Certificate") changing the Company's name to
"VCampus, Inc." The Board also recommended that the proposed amendment and
restatement be submitted to the Company's stockholders for consideration at the
Meeting. To effect the name change, the Certificate would be amended by deleting
Article I in its entirety and inserting the following in lieu thereof:

     "The name of the corporation is VCampus, Inc."

     The Board is recommending the proposed change so that the name of the
Company will reflect the operating name of its major business. Management has
chosen VCampus, Inc. as the Company's primary operating name and plans to use it
as its universal brand name for its key businesses. Accordingly, the Board
believes alignment of the Company's name with its operating name will enhance
the Company's brand equity and strengthen recognition of the Company by its
customers, partners and stockholders.

VOTE REQUIRED

     The affirmative vote of the holders of a majority of the shares of the
Company's Common Stock, Series C Preferred Stock and Series D Preferred Stock
present or represented and voting together as one class on this proposal at the
Meeting will be required to approve this proposal. Votes withheld on this
proposal will be counted for purposes of determining the presence or absence of
a quorum for the transaction of business and will be treated as shares
represented and voting on this proposal at the Meeting. In accordance with
Delaware law, abstentions will be counted for purposes of determining both
whether a quorum is present at the Meeting and the total number of shares
represented and voting on this proposal. While broker non-votes will be counted
for purposes of determining the presence or absence of a quorum, broker
non-votes will not be counted for purposes of determining the number of shares
represented and voting with respect to the particular proposal on which the
broker has expressly not voted and, accordingly, will not affect the approval of
this proposal.

     If the proposal is approved, officers of the Company will promptly make
appropriate filings in the State of Delaware and take any other actions
necessary to implement the name change.

     The name change will not affect the validity or transferability of
currently outstanding stock certificates, and stockholders will not be requested
to surrender for exchange any certificates presently held by them. The Company
is considering changing its ticker symbol on the Nasdaq SmallCap Market to
reflect the new name.

     THE BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED AND RECOMMENDS A VOTE "FOR"
THE PROPOSED NAME CHANGE.

                               PROPOSAL NO. 3 --
                  APPROVAL OF AMENDMENT TO THE 1996 STOCK PLAN

     The Company's 1996 Stock Plan (the "1996 Plan") was adopted and approved by
the Board of Directors in August 1996 and by the stockholders of the Company in
September 1996. A total of 2,524,893 shares of Common Stock have been reserved
for issuance under the 1996 Plan, 1,000,000 of which are subject to stockholder
approval at the Meeting. As of June 30, 1999, 6,437 shares of Common Stock had
been issued upon exercise of options granted under the 1996 Plan, and options
for 1,271,227 shares were outstanding

                                        4
<PAGE>   7

thereunder at a weighted average exercise price of $10.86 per share. The 1996
Plan also allows for the grant of purchase rights, under which 27,619 shares
have been purchased to date. Absent stockholder approval, only 199,610 shares
remain available for issuance under the 1996 Plan as incentive stock options and
all future grants from the 1,000,000 shares subject to this proposal will not
qualify as incentive stock options.

     The 1996 Plan provides for the grant of "incentive stock options" within
the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code"), solely to employees (including officers and employee directors), and
nonstatutory stock options to employees, directors and consultants.

     In order to tie director compensation more directly to the individual
director's contributions to the Company, the 1996 Plan includes an automatic
grant program for non-employee directors. This program provides for automatic
grants on January 1 of each year to directors who are not employees of the
Company of an option to purchase 10,000 shares. In addition, in the case of a
new director, automatic grants shall be effective upon such director's initial
election or appointment to the Board with the number of underlying shares equal
to the product of 2,500 multiplied by the number of regularly scheduled meetings
remaining in that year. Subject to continued status as a director, options
granted pursuant to the automatic grant program vest 25% per year on each of the
fifth, sixth, seventh and eighth anniversaries of the date of grant; provided,
however, that 2,500 shares vest on each date the director attends a Board
meeting in person during that year. In addition, each such director will
automatically be granted a fully-vested option to purchase an additional 2,500
shares on each date the director attends a meeting of a committee of the Board
other than on the same day or within one day of a Board meeting.

     As of June 30, 1999, approximately 110 persons were eligible to receive
grants under the 1996 Plan. The 1996 Plan is administered by the Compensation
Committee of the Board of Directors. Subject to the restrictions of the 1996
Plan, the Compensation Committee determines who is granted options, the terms of
options granted, including exercise price, the number of shares subject to the
option and the option's exercisability. The current members of the Compensation
Committee are Messrs. deCastro and Fingerhut.

     The exercise price of options granted under the 1996 Plan is determined on
the date of grant, and in the case of incentive stock options must be at least
100% of the fair market value per share at the time of grant. The exercise price
of any option granted to an optionee who owns stock possessing more than 10% of
the voting power of the Company's outstanding capital stock must equal at least
110% of the fair market value of the Common Stock on the date of grant. The
aggregate fair market value of Common Stock (determined as of the date of the
option grant) for which incentive stock options may for the first time become
exercisable by any individual in any calendar year may not exceed $100,000.
Payment of the exercise price may be made by delivery of cash or a check to the
order of the Company, or by any other means determined by the Board of
Directors.

     Options granted to employees under the 1996 Plan generally become
exercisable in increments, based on the optionee's continued employment with the
Company, over a period of up to five years. The term of an incentive stock
option may not exceed 10 years. The form of option agreement generally provides
that options granted under the 1996 Plan, whether incentive stock options or
nonstatutory options, expire 10 years from the date of grant. Incentive stock
options granted pursuant to the 1996 Plan are not transferable by the optionee,
other than by will or the laws of descent and distribution, and are exercisable
during the optionee's lifetime only by the optionee. Generally, in the event of
a merger of the Company with or into another corporation or a sale of all or
substantially all of the Company's assets, all outstanding options under the
1996 Plan shall accelerate and become fully exercisable upon consummation of
such merger or sale of assets.

     The Board may amend the 1996 Plan at any time or from time to time or may
terminate the 1996 Plan without the approval of the stockholders, provided that
stockholder approval is required for any amendment to the 1996 Plan requiring
stockholder approval under applicable law as in effect at the time. However, no
action by the Board of Directors or stockholders may alter or impair any option
previously granted under the 1996 Plan. The Board may accelerate the
exercisability of any option or waive any condition or restriction pertaining to
such option at any time. The 1996 Plan will terminate in August 2006, unless
terminated sooner by the Board.

TAX CONSEQUENCES OF OPTIONS

     An optionee who is granted an incentive stock option will generally not
recognize taxable income either at the time the option is granted or upon its
exercise, although the exercise will increase the optionee's alternative minimum
taxable income by an amount equal to the difference, if any, between the fair
market value of the shares at the time of exercise and the option's exercise
price, and therefore may subject the optionee to the alternative minimum tax.
Upon the sale or exchange of the shares more than two years after grant of the
option and more than one year after exercising the option, any gain or loss will
be treated as long-term capital gain or loss. If these holding periods are not
satisfied, the optionee will recognize ordinary income at the time of sale or
exchange equal to the difference between the exercise price and the lower of (i)
the fair market value of the shares at the date of the option's exercise or (ii)
the sale price of the shares. The Company will be entitled to a deduction in the
same amount as the ordinary income recognized by the optionee. Any gain or loss
recognized on such a premature disposition of the shares in excess of the amount
treated as ordinary income will be characterized as long-term or short-term
capital gain or loss, depending on the optionee's holding period with respect to
such shares.

     All other options that do not qualify as incentive stock options are
referred to as nonstatutory options. Generally, an optionee will not recognize
any taxable income at the time he or she is granted a nonstatutory option. Upon
its exercise, however, the optionee will generally recognize taxable ordinary
income measured as the excess of the then fair market value of the shares
acquired over the exercise price of the option. Any taxable income recognized in
connection with an option exercise by an optionee who is also an employee of the
Company will be subject to tax withholding by the Company. The Company will be
entitled to a tax deduction in the same amount as the ordinary income recognized
by the optionee with respect to shares acquired upon exercise of a nonstatutory
option. Upon resale of such shares by the optionee, any difference between the
sales price received and the fair market value for the shares on the date of
exercise of the option will be treated as long-term or short-term capital gain
or loss, depending on the optionee's holding period with respect to such shares.

     The foregoing is only a summary, based on the current Code and Treasury
Regulations thereunder, of the federal income tax consequences to the optionee
and the Company with respect to the grant and exercise of options under the 1996
Plan, does not purport to be complete, and does not discuss the tax consequences
of the optionee's death or the income tax laws of any municipality, state or
foreign country in which an optionee may reside.

PROPOSED AMENDMENT

     In February 1999, the Board of Directors adopted an amendment to the 1996
Plan to increase the number of shares reserved for issuance thereunder by
1,000,000 shares, from 1,524,893 shares to 2,524,893 shares (the "Share Amount
Amendment"). Without giving effect to the Share Amount Amendment, as of March
31, 1999, only 199,610 shares remained available for future grant as incentive
stock options under the 1996 Plan, which will not allow the Company to meet its
anticipated needs with respect to the issuance of such additional options to
employees and consultants of the Company. Absent stockholder approval, all
future grants from the 1,000,000 additional shares subject to this proposal will
fail to qualify for favorable tax treatment as incentive stock options.

     At the Meeting, the stockholders are being asked to approve the Share
Amount Amendment.

VOTE REQUIRED

     The affirmative vote of the holders of a majority of the shares of the
Company's Common Stock, Series C Preferred Stock and Series D Preferred Stock
present or represented and voting together as one class on this proposal at the
Meeting will be required to approve the Share Amount Amendment. Failure to
obtain stockholder approval of the Share Amount Amendment will prevent the
Company from granting incentive stock options out of the additional 1,000,000
shares, but will not necessarily prevent the Company from otherwise granting
other awards under the 1996 Plan.

     Votes withheld on this proposal will be counted for purposes of determining
the presence or absence of a quorum for the transaction of business and will be
treated as shares represented and voting on this proposal at

                                        6
<PAGE>   9

the Meeting. In accordance with Delaware law, abstentions will be counted for
purposes of determining both whether a quorum is present at the Meeting and the
total number of shares represented and voting on this proposal. While broker
non-votes will be counted for purposes of determining the presence or absence of
a quorum, broker non-votes will not be counted for purposes of determining the
number of shares represented and voting with respect to the particular proposal
on which the broker has expressly not voted and, accordingly, will not affect
the approval of this proposal.

     THE BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED AND RECOMMENDS A VOTE "FOR"
THE PROPOSED AMENDMENT TO THE 1996 PLAN.

                    NASDAQ STOCKHOLDER APPROVAL REQUIREMENTS

     Proposals No. 4 and 5 below are submitted for stockholder approval pursuant
to Nasdaq Marketplace Rule 4460(i), which is one of several non-quantitative
designation criteria required of a Nasdaq SmallCap Market issuer, such as the
Company. One of the events that necessitate prior stockholder approval pursuant
to Rule 4460(i) is as follows:

     - in connection with a transaction other than a public offering involving
       the sale or issuance by the issuer of common stock (or securities
       convertible into or exercisable for common stock) equal to 20% or more of
       the common stock or 20% or more of the voting power outstanding before
       the issuance for less than the greater of book or market value of the
       stock.

     Because each of the proposed financing arrangements described in Proposals
No. 4 and 5 involve the potential issuance by the Company of common stock
greater than 20% of the Company's currently outstanding common stock (the "20%
Share Limitation") at below market value, each of the Proposals are subject to
Rule 4460(i) and, therefore, require your approval. Absent such approval, the
Company could be limited to issuing no more than as few as approximately 962,272
shares of common stock in connection with such financings (based on the number
of shares of common stock outstanding on the Record Date).

     If the Company does not obtain approval from its stockholders for Proposals
No. 4 and 5, but the Company nonetheless issues common stock (or preferred
stock, warrants or debentures convertible into or exercisable for common stock)
as described in such Proposals, Nasdaq could delist the Company's common stock
on the Nasdaq SmallCap Market. If this happens, the common stock could be traded
in the Over-the-Counter market on the OTC Electronic Bulletin Board, an
electronic bulletin board established for securities that do not meet the Nasdaq
SmallCap Market listing requirements, in what is commonly referred to as the
"pink sheets." In such an event, the market price of the common stock may be
adversely impacted and you may find it difficult to dispose, or obtain accurate
quotations as to the market value, of your shares of common stock. In addition,
the Company could find it more difficult to obtain future financing.

                PROPOSAL NO. 4 -- APPROVAL OF THE H&Q FINANCING

THE EQUITY LINE AGREEMENT

     The Company requires additional working capital to support its operations.
In an effort to meet these capital requirements, on May 4, 1999 the Company
entered into a Private Equity Line of Credit Agreement (the "Equity Line
Agreement") with Hambrecht & Quist Guaranty Finance, LLC ("H&Q"). Under the
Equity Line Agreement, the Company has the right, subject to certain conditions,
to issue and sell to H&Q, from time to time, shares of its Series E Convertible
Preferred Stock (the "Put Shares") for cash consideration of up to an aggregate
of $3,000,000, subject to availability (the "H&Q Financing").

     Under the Equity Line Agreement, the Company is required to file a
Registration Statement with the SEC in order to permit H&Q to resell to the
public or in privately negotiated transactions any shares of common stock that
it acquires pursuant to the Equity Line Agreement. Beginning on the date the
Registration Statement is declared effective by the Commission and ending on
December 31, 1999, the Company has the right from time to time at its sole
discretion, and subject to certain restrictions and conditions set forth in the
Equity Line Agreement, to sell the Put Shares to H&Q at a price equal to 85% of
the then current average

                                        7
<PAGE>   10

market price of the Company's common stock. The market price for purposes of
this calculation is the lower of:

     (1) the average of the lowest intra-day prices of the common stock on the
         Nasdaq SmallCap Market for the five days beginning two days before and
         ending two days after the Company notifies H&Q of its intention to sell
         Put Shares to H&Q; or

     (2) the closing price of the common stock on such date.

Puts can be made every 15 days in amounts not to exceed $500,000. As of the date
of this Proxy Statement, no shares have been sold to H&Q under the Equity Line
Agreement.

     The Company's ability to sell Put Shares, and H&Q's obligation to purchase
the Put Shares, is conditioned upon the satisfaction of certain conditions with
respect to any put date. These conditions include:

     (1) the Registration Statement must have been declared effective by the SEC
         and shall remain effective;

     (2) the representations and warranties of the Company set forth in the
         Equity Line Agreement must be accurate in all material respects as of
         the date of each put;

     (3) the Company must have performed and complied with all of its
         obligations under the Equity Line Agreement and a registration rights
         agreement entered into between the Company and H&Q and a warrant issued
         to H&Q;

     (4) no statute, rule, regulation, executive order, decree, ruling or
         injunction may be in effect which prohibits or adversely affects any of
         the transactions contemplated by the Equity Line Agreement;

     (5) the Company's common stock must not have been suspended from trading
         and such stock shall have been approved for listing or quotation on and
         shall not have been delisted from its then applicable principal trading
         market (currently the Nasdaq SmallCap Market); and

     (6) the number of Put Shares to be sold to H&Q, together with any shares
         then beneficially held by H&Q, may not exceed 9.9% of all shares of the
         Company's common stock that would be outstanding upon completion of the
         put (the "9.9% Limitation"). Based on the number of shares of common
         stock outstanding on the Record Date and the closing price of $6.5625
         on July 1, 1999, and assuming H&Q does not resell any shares issued to
         it, this limitation restricts the amount of money the Company can raise
         under the Equity Line Agreement to approximately $2.6 million; If the
         price of the common stock drops, this amount will decrease.

TERMS OF THE SERIES E PREFERRED "PUT" SHARES

     The terms of the Put Shares are complex. Any summary of the terms will be
general in nature and must be qualified by reference to the actual agreements.
The Equity Line Agreement with H&Q and the Certificate of Designations,
Preferences and Rights of Series E Convertible Preferred Stock are attached to
this Proxy Statement as Appendices A and B, respectively. We urge any
stockholders desiring a more detailed understanding of the terms of the Put
Shares to refer to such Appendices. The following is a summary of such terms:

     Rank.  The Put Shares shall, with respect to dividend rights and rights
upon liquidation, rank equal with the Company's Series C Preferred Stock and
Series D Preferred Stock and senior to common stock.

     Dividends.  The holders of Put Shares will be entitled to receive a 6%
annual dividend, payable monthly in additional Put Shares at 85% of the average
of the lowest closing prices of the common stock on the applicable principal
trading market for such stock on the date of the dividend and the four trading
days prior to such date.

     Conversion Rate.  At any time, any holder of Put Shares may convert all or
a portion of such shares into a number of shares of common stock computed by
multiplying the number of Put Shares to be converted by the purchase price
thereof and dividing the result by the Conversion Price (as described below)
then in effect. The initial conversion rate will be one-for-one.

                                        8
<PAGE>   11

     Conversion Price.  The Conversion Price with respect to any group of Put
Shares shall initially be the purchase price paid for such shares, as may be
adjusted from time to time to account for any stock splits, stock dividends,
recapitalizations, mergers, asset sales or similar events.

     Liquidation.  Upon a change in control, liquidation, dissolution or winding
up of the affairs of the Company, the holders of Put Shares will be entitled,
equally with the holders of the Company's Series C and D Preferred Shares, to a
liquidation preference prior in right to any holders of common stock. The
liquidation preference for the Put Shares will equal an amount per share equal
to the per share price paid for the Put Shares.

     Voting.  The holders of Put Shares will be entitled to vote on all matters
submitted to stockholders for a vote, which shares shall vote together with the
holders of common stock voting together as a single class, with each Put Share
entitled to one vote for each share of common stock into which it is
convertible. The holders of Put Shares are entitled to vote as a separate class
on the creation of any new series of preferred stock or the issuance of
additional shares of capital stock ranking senior or equal to the Put Shares.

     Registration Rights.  As a condition to drawing down on the Equity Line
Agreement, the Company is required to file and have declared effective a
registration statement registering the common stock underlying the Put Shares.

     Consummation of the H&Q Financing will require one or more amendments to
the Company's Certificate of Incorporation to establish the Series E Convertible
Preferred Stock described above. Your approval of the H&Q Financing will
constitute approval for such amendments.

     Securities such as the Put Shares that may be converted into common stock
at a price lower than the future market price of the common stock are often
referred to as "Future-Priced Securities." Because the conversion rate of the
Put Shares cannot be determined and there is no limit on the number of shares of
common stock into which the Put Shares may be converted (other than the 9.9%
Limitation), if stockholders approve this transaction and the issuance of a
Future-Priced Security is followed by a decline in the common stock price, the
existing holders of common stock could face substantial dilution of their voting
power and percentage ownership in the Company. Additionally, as the Company
issues more shares, the price of the common stock may decline further.

TERMS OF THE WARRANT

     Simultaneous with the execution of the Equity Line Agreement on May 4,
1999, the Company issued a warrant (the "Warrant") to H&Q entitling H&Q to
purchase 100,000 shares of the Company's Series E Convertible Preferred Stock at
$3.6675 per share, subject to adjustments for stock splits, stock dividends,
reorganizations, mergers and similar events (which initial exercise price was
determined by taking 120% of the average closing price of the common stock over
the five trading days ending on the date of grant). The exercise price is
subject to an anti-dilution adjustment if the Company issues certain new
securities at a price below the Warrant exercise price. The Warrant is
exercisable through May 31, 2006. The shares of common stock underlying the
Warrant have the same registration rights as the common stock underlying the Put
Shares.

EFFECT OF NASDAQ MARKETPLACE RULE 4460(i)

     Because the H&Q Financing involves the potential below-market issuance of
shares exceeding Nasdaq's 20% Share Limitation described above, stockholder
approval is required before the Company could properly issue more than as few as
approximately 962,272 shares of common stock (based on the number of outstanding
shares on the Record Date) to H&Q upon conversion of Put Shares. Absent
stockholder approval, the Company would not be able to draw down a significant
portion of the funds available under the equity line, which are currently needed
for working capital.

VOTE REQUIRED

     The affirmative vote of the holders of a majority of the shares of the
Company's Common Stock, Series C Preferred Stock and Series D Preferred Stock
present or represented and voting together as one class on this proposal at the
Meeting will be required to approve the H&Q Financing. In addition, separate
approval will be required by the holders of a majority of the shares of the
Company's Series C Preferred Stock and Series D

                                        9
<PAGE>   12

Preferred Stock, each voting as a separate class. In accordance with Delaware
law, abstentions will be counted for purposes of determining both whether a
quorum is present at the Meeting and the total number of shares represented and
voting on this proposal. Thus, abstentions will have the effect of a vote
against this proposal. While broker non-votes will be counted for purposes of
determining the presence or absence of a quorum for the transaction of business,
they will not be counted for purposes of determining the number of shares
represented and voting with respect to the particular proposal on which the
broker has expressly not voted, and, accordingly, will not affect approval of
this proposal.

BOARD RECOMMENDATIONS; REASONS

     Based primarily on its consideration of the factors described below, the
Board believes that the consummation of the H&Q Financing is in the best
interests of the Company and its stockholders.

     Among the factors considered by the Board in approving the H&Q Financing
was the Board's view that the proceeds from the financing are necessary to
support the Company's near-term working capital requirements, as well as its
growth over the longer term. The Board determined that the economic terms of the
proposed financing would be of substantial benefit to the Company and its
stockholders and that the financing is fair to the Company's stockholders from a
financial point of view. In reaching its determination, the Board considered the
purchase price to be paid for the Put Shares and its relationship to the trading
prices of the common stock prior to the execution of the Equity Line Agreement.

     THE BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE H&Q FINANCING AND
RECOMMENDS THAT YOU VOTE FOR ITS APPROVAL.

       PROPOSAL NO. 5 -- APPROVAL OF THE CONVERTIBLE DEBENTURE FINANCING

     As part of the Company's continuing efforts to meet its working capital
needs, effective on June 4, 1999, the Company secured additional financing from
Excalibur Limited Partnership and B.H. Capital Investments, L.P. through the
issuance of $2,500,000 in convertible debentures (the "Debentures"), bearing
interest at nine percent (9%) simple interest and maturing on December 15, 2000,
if not sooner converted (the "Convertible Debenture Financing"). Depending on
the Company's stock price at the time of a repayment, repayments of principal
and interest under the Debentures may be made either in cash or through the
issuance of the Company's common stock. The initial conversion price for the
Debentures is $5.55 per share, based on the 5-day average closing price of the
Company's common stock prior to closing.

     Under the terms of the Convertible Debenture Financing, beginning September
15, 1999, the holders of the Debentures can demand monthly repayment of up to
15% of the principal outstanding under the Debentures, on a cumulative basis.
Upon any such demand, the Company must make repayments either in cash or its
common stock as follows:

     (1) If the 5-day average closing price of the Company's common stock at the
         time of a repayment is HIGHER than the fixed conversion price of $5.55
         per share, then the repayment must be made in the Company's common
         stock at the fixed price;

     (2) If the 5-day average closing price of the Company's common stock at the
         time of a repayment is LOWER than the fixed conversion price of $5.55,
         then the repayment must be made in cash as follows:

        (a) Prior to January 15, 2000, at 110% of the amount of repayment
            requested, plus accrued interest, and the Company must issue an
            additional warrant to the holders of the Debentures to purchase an
            additional 22,520 shares of common stock;

        (b) After January 15, 2000, at 115% of the amount of repayment
            requested, plus accrued interest.

        Provided, however, if the Company is unable or unwilling to make any
        repayment in cash as required, the Company may elect to make such
        repayment in common stock valued at 85% of the average of the two lowest
        consecutive closing bid prices for such stock during the 20-day trading
        period prior to the repayment request. However, to the extent available,
        the Company intends to use funds available under the H&Q equity line of
        credit to make repayments in cash rather than permit any conversions at
        less than the fixed conversion price of $5.55 per share.

                                       10
<PAGE>   13

     In connection with the Convertible Debenture Financing, the Company also
issued warrants to the investors for the purchase of 112,600 shares at a strike
price of $6.38 per share (determined based on 115% of the 5-day average closing
bid price of the Company's common stock prior to the issuance date of the
warrant). The warrants are exercisable until June 4, 2004.

     The Company has agreed to file within 45 days after closing a registration
statement for the registration of the common stock issuable upon conversion of
the Debentures and exercise of the related warrants and to have such
registration statement declared effective within 90 days of closing (or 120 days
from closing if the SEC reviews the registration statement). The Company paid
$25,000 for the investors' legal and due diligence expenses relating to the
financing.

     The terms of the Debentures are complex. Any summary of the terms will be
general in nature and must be qualified by reference to the actual agreements.
The purchase agreement and the related Debenture are attached to this Proxy
Statement as Appendices C and D, respectively. We urge any stockholders desiring
a more detailed understanding of the terms of the Convertible Debenture
Financing to refer to such Appendices.

     Because the conversion price of the Debentures can decrease if the market
price of the Company's common stock falls below $5.55 per share, unless the
Company can and does elect to repay the Debentures in cash as described above,
there would be no limit on the number of shares of common stock into which the
Debentures may be converted (other than a restriction limiting the amount the
investors can own at any given time to 9.9% of the outstanding shares), if
stockholders approve this transaction and the market price of the common stock
declines, the existing holders of common stock could face substantial dilution
of their voting power and percentage ownership in the Company.

EFFECT OF NASDAQ MARKETPLACE RULE 4460(i)

     Because the Convertible Debenture Financing involves the potential
below-market issuance of shares exceeding Nasdaq's 20% Share Limitation
described above, stockholder approval is required. Absent stockholder approval,
Nasdaq could delist the Company's common stock on the Nasdaq SmallCap Market,
which could adversely affect the marketability of your shares.

VOTE REQUIRED

     The affirmative vote of the holders of a majority of the shares of the
Company's Common Stock, Series C Preferred Stock and Series D Preferred Stock
present or represented and voting together as one class on this proposal at the
Meeting will be required to approve the Convertible Debenture Financing. In
accordance with Delaware law, abstentions will be counted for purposes of
determining both whether a quorum is present at the Meeting and the total number
of shares represented and voting on this proposal. Thus, abstentions will have
the effect of a vote against this proposal. While broker non-votes will be
counted for purposes of determining the presence or absence of a quorum for the
transaction of business, they will not be counted for purposes of determining
the number of shares represented and voting with respect to the particular
proposal on which the broker has expressly not voted, and, accordingly, will not
affect approval of this proposal.

BOARD RECOMMENDATIONS; REASONS

     Based primarily on its consideration of the factors described below, the
Board believes that the Convertible Debenture Financing is in the best interests
of the Company and its stockholders.

     Among the factors considered by the Board in approving the Convertible
Debenture Financing was the Board's view that the proceeds from the financing
are necessary to support the Company's near-term working capital requirements,
and in particular will give the Company bridge financing until the H&Q Financing
can be completed. The Board determined that the economic terms of the proposed
financing would be of substantial benefit to the Company and its stockholders
and that the financing is fair to the Company's stockholders from a financial
point of view. In reaching its determination, the Board considered the
conversion price for the Debentures and its relationship to the trading prices
of the common stock prior to execution of the financing agreements, as well as
the Company's right to repay in cash if the conversion price would be below
$5.55 per share.

                               PROPOSAL NO. 6 --
               RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

     The Board of Directors of the Company has appointed the firm of Ernst &
Young LLP, Vienna, Virginia, to serve as the independent auditors of the Company
for the fiscal year ending December 31, 1999, and recommends that the
stockholders ratify such action. Ernst & Young LLP has audited the accounts of
the Company since 1994 and has advised the Company that it does not have, and
has not had, any direct or indirect financial interest in the Company or its
subsidiaries in any capacity other than that of serving as independent auditors.
Representatives of Ernst & Young LLP are expected to attend the Meeting. They
will have an opportunity to make a statement, if they desire to do so, and will
also be available to respond to appropriate questions.

     The affirmative vote of the holders of a majority of the shares of the
Company's Common Stock, Series C Preferred Stock and Series D Preferred Stock
present or represented and voting together as one class on this proposal at the
Meeting shall constitute ratification of the appointment of Ernst & Young LLP.
If the appointment of Ernst & Young LLP is not ratified by the stockholders, the
Board of Directors will reconsider its selection.

     THE BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED AND RECOMMENDS A VOTE "FOR"
THE RATIFICATION OF THE APPOINTMENT OF ERNST & YOUNG LLP AS INDEPENDENT AUDITORS
OF THE COMPANY FOR THE FISCAL YEAR ENDING DECEMBER 31, 1999.

                               OTHER INFORMATION

PRINCIPAL STOCKHOLDERS

     The following table sets forth certain information regarding the ownership
of shares of the Company's Common Stock, Series C Preferred Stock and Series D
Preferred Stock as of the Record Date by (1) each person known by the Company to
beneficially own more than 5% of the outstanding shares of Common Stock, (2)
each director and director nominee of the Company, (3) each of the Named
Officers, as listed under "-- Executive Compensation -- Summary Compensation"
below, and (4) all directors and executive officers of the Company as a group.
As of the Record Date the Company had outstanding (1) 4,811,365 shares of Common
Stock, (2) 623,339 shares of Series C Preferred Stock (convertible into 755,549

EMPLOYMENT AGREEMENTS

     Under the terms of the Company's form of employment agreement for executive
officers, such officers are entitled to annual incentive-based bonus
compensation of up to 50% of their base salary. The exact amount of such
compensation is determined by the Company's Board of Directors, generally based
upon the achievement

                                       17
<PAGE>   20

of specified performance goals established by the Board. Under such agreements,
executive officers are also eligible to participate in all employee benefit
plans and programs that the Company offers to its executive employees and are
entitled to reimbursement for all documented reasonable business expenses they
incur. Generally, consistent with Company policies, in the event that an
executive officer is terminated without cause or resigns for good cause, the
Company is required under its form of employment agreement to continue paying
salary to such officer for six to nine months as severance.

     Mr. Kannan's employment agreement with the Company provides for an annual
base salary of $180,000. The term of the agreement expired in June 1999, but the
agreement is subject to automatic one-year renewal terms. In the event of a
material change in Mr. Kannan's duties, titles, authority or position with the
Company, he may elect, in lieu of receiving his severance pay, to enter into a
consulting arrangement with the Company, whereby Mr. Kannan would provide
consulting services to the Company for a period of one year and be paid $750 per
day for providing such services.

     Following termination of Mr. Tyson's employment with the Company in October
1998, the Company began paying Mr. Tyson a severance equal to nine months of his
base salary, or $170,100, pursuant to the terms of his employment agreement.

COMPENSATION OF DIRECTORS

     All directors are reimbursed for expenses incurred in connection with each
board committee meeting attended.

     The 1996 Plan provides for the grant of nonstatutory options to
non-employee directors of the Company. The 1996 Plan provides automatic grants
on January 1 of each year to directors who are not employees of the Company of
an option to purchase 10,000 shares. In addition, in the case of a new director,
automatic grants shall be effective upon such director's initial election or
appointment to the Board with the number of underlying shares equal to the
product of 2,500 multiplied by the number of regularly scheduled meetings
remaining in that year. Subject to continued status as a director, options vest
25% per year on each of the fifth, sixth, seventh and eighth anniversaries of
the date of grant; provided, however, that 2,500 shares vest on each date the
director attends a Board meeting in person during that year. In addition, such
director will automatically be granted a fully-vested option to purchase an
additional 2,500 shares on each date the director attends a meeting of a
committee of the Board other than on the same day or within one day of a Board
meeting.

     Under the 1996 Plan, during 1998 the non-employee directors received
options as follows: Mr. Fingerhut -- 10,000; Mr. Wallman -- 17,500; Mr.
Kimberly -- 17,500; Mr. Sears -- 7,500; and Mr. deCastro -- 10,000.

REPORT OF THE COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION

     The Compensation Committee (the "Committee") of the Board of Directors is
responsible for establishing compensation policy and administering the
compensation programs of the Company's executive officers. The purpose of this
report is to inform stockholders of the Company's compensation policies for
executive officers and the rationale for the compensation paid to executive
officers in 1998.

     The Compensation Committee of the Board of Directors, consisting entirely
of non-employee directors, approves all policies under which compensation is
paid or awarded to the Company's executive officers. The Compensation Committee
is currently composed of Messrs. Fingerhut and deCastro. The members of the
Compensation Committee also administer the Company's stock plans.

     For compensation paid to the Chief Executive Officer and other Named
Officers in 1998, no reference was made to the data for comparable companies
included in the performance graph included in this proxy statement under the
heading "-- Performance Graph" (the "Performance Graph").

     Compensation Philosophy.  The Company's executive compensation program has
three objectives: (1) to align the interests of the executive officers with the
interest of the Company's stockholders by basing a significant portion of an
executive's compensation on the Company's performance; (2) to attract and retain
highly talented and productive executives; and (3) to provide incentives for
superior performance by the

                                       18
<PAGE>   21

Company's executives. To achieve these objectives, the Compensation Committee
has crafted a program that consists of base salary, short-term incentive
compensation in the form of cash bonuses and long-term incentive compensation in
the form of stock options. These compensation elements are in addition to the
general benefits programs which are offered to all of the Company's employees.

     Each year, the Compensation Committee reviews the Company's executive
compensation program. In its review, the Compensation Committee studies the
compensation packages for executives of companies at a comparable stage of
development and in the Company's geographical area, assesses the competitiveness
of the Company's executive compensation program and reviews the Company's
financial and operational performance for the previous fiscal year. The
Compensation Committee also gauges the success of the compensation program in
achieving its objectives in the previous year, and considers the Company's
overall performance objectives.

     Each element of the Company's executive compensation program is discussed
below.

     Base Salaries.  The Compensation Committee annually reviews the base
salaries of the Company's executive officers. The base salaries for the
Company's executive officers for 1998 were established at the beginning of that
fiscal year, or when the executive joined the Company, as the case may be. In
addition to considering the factors listed in the foregoing section that support
the Company's executive compensation program generally, the Compensation
Committee reviews the responsibilities of the specific executive position and
the experience and knowledge of the individual in that position. The
Compensation Committee also measures individual performance based upon a number
of factors, including measurement of the Company's historic and recent financial
and operational performance and the individual's contribution to that
performance, the individual performance on non-financial goals and other
contributions of the individual to the Company's success, and gives each of
these factors relatively equal weight without confining its analysis to a
rigorous formula. As is typical of most corporations, the actual payment of base
salary is not conditioned upon the achievement of any predetermined performance
targets.

     Incentive Compensation.  Cash bonuses established for executive officers
are intended to motivate the individual to work hard to achieve the Company's
financial and operational performance goals or to otherwise incent the
individual to aim for a high level of achievement on behalf of the Company in
the coming year. Because the Company has been in the early stages of
development, it has not historically paid cash bonuses. However, in 1998,
bonuses were paid to the HTR executives pursuant to the terms of the HTR
acquisition effected in October 1997. The Compensation Committee does not have
an exact formula for determining bonus payments, but has established general
target bonus levels (up to a maximum of 50% of base salary) for executive
officers based in relatively equal measures upon the Compensation Committee's
subjective assessment of the Company's projected revenues and net income, and
other operational and individual performance factors. The Committee may adjust
these targets during the year.

     Long-Term Incentive Compensation.  The Company's long-term incentive
compensation plan for its executive officers is based upon the Company stock
plans. The Company believes that placing a portion of its executives' total
compensation in the form of stock options achieves three objectives. It aligns
the interest of the Company's executives directly with those of the Company's
stockholders, gives executives a significant long-term interest in the Company's
success and helps the Company retain key executives. Options generally vest over
a three to five-year period based upon continued employment. In December 1996,
and again in May and December 1998, the Company granted performance-based
options to the Chief Executive Officer and various other executive officers.
These grants vest ratably over four years beginning five years from the date of
grant, subject to accelerated vesting in full during the first four years after
the grant date if the fair market value of Company's Common Stock over
consecutive 20 trading days is greater than a target price representing a
four-year compounded return of 22.5% per year on the stock's fair market value
at the date of grant.

     In determining the number of options to grant an executive, the Board
primarily considered the executive's past performance and the degree to which an
incentive for long-term performance would benefit the Company, as well as the
number of shares and options already held by the executive officer. It is the
Compensation Committee's policy to grant options at fair market value unless
particular circumstances warrant otherwise.
                                       19
<PAGE>   22

     Benefits.  The Company believes that it must offer a competitive benefit
program to attract and retain key executives. During fiscal 1998, the Company
provided the same medical and other benefits to its executive officers that are
generally available to its other employees.

     Compensation of the Chief Executive Officer.  The Chief Executive Officer's
compensation is based upon the same elements and measures of performance as is
the compensation for the Company's other executive officers. The Compensation
Committee approved a base salary for Mr. Kannan for 1998 of $180,000. In
structuring the compensation of Mr. Kannan, the Compensation Committee
considered the alignment of his compensation package with the financial
performance of the Company to be essential. No bonus was paid to Mr. Kannan for
1998.

     Section 162(m) of the Code.  It is the responsibility of the Compensation
Committee to address the issues raised by Section 162(m) of the Code. Revisions
to this Section made certain non-performance based compensation in excess of
$1,000,000 to executives of public companies non-deductible to such companies
beginning in 1994. The Compensation Committee has reviewed these issues and has
determined that it is not necessary for the Company to take any action at this
time with regard to these issues.

     Neither the material in this report, nor the Performance Graph, is
soliciting material, is or will be deemed filed with the Securities and Exchange
Commission or is or will be incorporated by reference in any filing of the
Company under the Securities Act of 1933 or the Exchange Act, whether made
before or after the date of this proxy statement and irrespective of any general
incorporation language in such filing.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     The Compensation Committee of the Board of Directors consists of Messrs.
deCastro and Fingerhut, none of whom was at any time during the fiscal year
ended December 31, 1998 or at any other time an officer or employee of the
Company. No executive officer of the Company serves as a member of the board of
directors or compensation committee of any entity which has one or more
executive officers serving as a member of the Board of Directors or the
Compensation Committee of the Company.

CERTAIN TRANSACTIONS

     In March 1997, the Company acquired Ivy Software, Inc., a Virginia
corporation that develops and distributes business and accounting software for
the academic education market, for $314,000 in cash and potential future
payments not to exceed approximately $862,000. In connection with this
transaction, the President and sole shareholder of Ivy, Robert N. Holt, entered
into a three-year consulting agreement with the Company. In September 1998, the
Company sold Ivy back to Mr. Holt for $250,000 in cash and a note receivable for
approximately $200,000. In connection therewith, all other payment obligations
of the Company to Mr. Holt were terminated (other than $35,000 already earned
and paid under the consulting agreement). The Company agreed to pay Mr. Holt his
standard consulting fee of $2,500 per day for any future services the Company
might request from him.

     In April 1997, the Company acquired Teletutor, an Illinois corporation that
develops, distributes and supports computer-based training courses for the data
and telecommunications industry. The terms of the transaction included a $3.0
million cash payment at closing and $2.0 million in the form of a promissory
note to be paid in cash ratably on the first, second and third anniversary dates
of the acquisition. In connection with this transaction, James R. Cooper,
formerly the President of Teletutor, entered into an employment agreement to
become an Executive Vice President of the Company, from which position he
resigned effective in March 1998. During the second quarter of 1998, the Company
made the first installment payment of $666,667

                                       21
<PAGE>   24

to the former Teletutor shareholders. In December 1998, the Company and the
former Teletutor stockholders restructured the terms of the note as follows: the
Company issued to such stockholders an aggregate of 105,000 shares of Common
Stock and three-year warrants to purchase 55,000 shares of its Common Stock at
an exercise price of $6.00 per share and executed a new non-interest bearing
promissory note for $826,666, payable in installments between March 15, 1999 and
April 15, 2000.

     In October 1997, the Company acquired HTR, Inc., a Delaware corporation
whose strategy is to deliver a total solution for corporate information
technology requirements through its suite of products and services which
includes traditional and on-site training, courseware and consulting, in
exchange for 585,940 shares of Common Stock, options and warrants to purchase an
additional 34,020 shares, the assumption of an aggregate of approximately $3.5
million of HTR debt and a combination of cash and notes payable in the aggregate
amount of approximately $600,000. In addition, the executive officers of HTR,
Messrs. Kaviani (who became a director and executive officer of the Company upon
closing of the acquisition), Arsanjani (who became an executive officer of the
Company upon closing of the acquisition) and Callahan (who became an executive
officer of the Company upon closing of the acquisition) became entitled to
receive bonuses in the aggregate amount of $690,000 in connection with their
execution of employment agreements to become Executive Vice Presidents of the
Company, payable no later than December 31, 1998. In June 1998, the executive
officers of HTR were paid approximately $270,000 of their bonuses in cash to
satisfy tax obligations and they agreed to convert the remaining approximately
$420,000 of such sign-on bonuses and $320,000 of acquisition-related
indebtedness into 134,447 shares of the Company's Series D convertible Preferred
Stock. In connection with the acquisition, the Company also created a stock
option pool of 180,000 shares of Common Stock and an incentive bonus pool with a
potential payout of up to approximately $3,300,000 over three years to such
officers (and one other executive officer of HTR), contingent upon the financial
performance of HTR. During 1998, none of this payout was made and none of these
option shares were granted to such executive officers. Mr. Callahan's employment
as an executive officer of the Company was terminated in June 1998.

     In March 1998, the Company raised approximately $5.3 million in gross
proceeds through a private placement (the "Series C Private Placement") of
626,293 shares of the Company's Series C Preferred Stock (which shares are
convertible into approximately 757,800 shares of Common Stock), together with
five-year warrants to purchase 626,293 shares of Common Stock at an exercise
price of $8.46 per share (the five-day average of the closing bid prices
calculated prior to closing of the Private Placement). Barry K. Fingerhut, a
director and one of the largest beneficial stockholders of the Company, and
other investors affiliated with Mr. Fingerhut, purchased an aggregate of 283,604
shares of Series C Preferred Stock and warrants to purchase an aggregate of
283,604 shares of Common Stock in the Series C Private Placement. The Series C
Preferred Stock has a liquidation preference of $12.69 per share upon the sale
or liquidation of the Company. The Common Stock issuable upon conversion of the
Series C Preferred Stock and exercise of the related warrants has certain
registration rights.

     In June 1998, the Company raised approximately $5.2 million in gross
proceeds through a private placement (the "Series D Private Placement") of
1,082,625 shares of the Company's Series D Preferred Stock (which shares are
convertible into Common Stock on a one-for-one basis). Barry K. Fingerhut, a
director and one of the largest beneficial stockholders of the Company, and
other investors affiliated with Mr. Fingerhut, purchased an aggregate of 445,452
shares of Series D Preferred Stock in the Series D Private Placement. 137,174
shares of the Series D Preferred Stock and 5,194 shares of UOL Common Stock were
issued in connection with the conversion of approximately $805,000 of
indebtedness, mainly to certain former shareholders of HTR. Pursuant to the
terms of the Series D Preferred Stock, the Company declared and issued a 5%
Common Stock dividend on the Series D Preferred Stock in December 1998.

     In May 1999, the Company raised approximately $1.32 million through a
private placement of 448,297 shares of common stock at a price of $2.9375 per
share. Barry K. Fingerhut, a director and the largest beneficial stockholder of
the Company, purchased an aggregate of 102,127 of such shares for an aggregate
consideration of $300,000. The holders of shares issued in this financing are
entitled to certain registration rights.

     In December 1996, the Company loaned Nat Kannan, the Company's founder,
Chief Executive Officer and Chairman, $100,000 to help satisfy Mr. Kannan's
income tax withholding obligations relating to back

                                       22
<PAGE>   25

wages paid to Mr. Kannan by the Company in 1996. The largest outstanding
principal amount under the loan, together with interest accrued thereon, during
1998 was approximately $116,000. The loan bears interest at the prime rate, as
announced from time to time by First Union National Bank, minus one percent with
principal and accrued interest payable in full upon demand.

sole discretion, terminate this Agreement in the event that: (a) there shall
occur any stop order or suspension of the effectiveness of the Registration
Statement for an aggregate of thirty (30) Trading Days during the Commitment

Period in accordance with the Registration Rights Agreement as a result of
corporate developments subsequent to the Subscription Date that would require

maintain its compliance with the disclosure requirements of the Securities Act;
or (b) the Company shall at any time fail to comply with the requirements of
Sections 6.3, 6.4, 6.5 or 6.6.

Trading Days following any Closing Date, the Company gives a Blackout Notice to
the Investor of a Blackout Period in accordance with the Registration Rights
Agreement, and (b) the Bid Price on the Trading Day immediately preceding such
Blackout Period ("Old Bid Price") is greater than the Bid Price on the first
Trading Day following such Blackout Period that the Investor may sell its
Registrable Securities pursuant to an effective Registration Statement ("New Bid
Price"), then the Company shall issue to the Investor the number of additional
shares of Registrable Securities (the "Blackout Shares") equal to the difference
between (x) the product of the number of Registrable Securities held by Investor
immediately prior to the Blackout Period multiplied by the Old Bid Price,
divided by the New Bid Price, and (y) the number of Registrable Securities held
by Investor immediately prior to the Blackout Period.

     Section 2.7  Liquidated Damages.  The parties hereto acknowledge and agree
that the requirement to issue Blackout Shares under Section 2.6 above shall
constitute liquidated damages and not penalties. The parties further acknowledge

enabling the Company to satisfy any obligation to issue Common Stock upon

Blackout Shares; such amount of shares of Common Stock to be reserved shall be
calculated based upon the minimum Purchase Price for the Put Shares under the

a good faith estimate by the Company in consultation with the Investor of the
number of Blackout Shares that will need to be issued. The number of shares so
reserved from time to time, as theretofore increased or reduced as hereinafter
provided, may be reduced by the number of shares actually delivered hereunder.

efforts to maintain the listing of the Common Stock on a Principal Market or
other exchange acceptable to the Investor. The Company shall use its best

terminate or suspend such registration or to terminate or suspend its reporting
and filing obligations under said Act.

     Section 6.5  Legends.  The certificates evidencing the Put Shares, the

or related prospectus in respect of an offering of Registrable Securities: (i)

qualification or exemption from

                                       A-9
<PAGE>   35

qualification of any of the Registrable Securities for sale in any jurisdiction
or the initiation or threatening of any proceeding for such purpose; (iv) the
happening of any event that makes any statement made in such Registration
Statement or related prospectus or any document incorporated or deemed to be
incorporated therein by reference untrue in any material respect or that
requires the making of any changes in the registration statement, related
prospectus or documents so that, in the case of the Registration Statement, it
will not contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading, and that in the case of the related prospectus, it will
not contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading; and (v) the Company's reasonable determination that a post-
effective amendment to the registration statement would be appropriate, and the
Company shall promptly make available to the Investor any such supplement or
amendment to the related prospectus. The Company shall not deliver to the
Investor any Put Notice during the continuation of any of the foregoing events.

after the commencement of each calendar quarter occurring subsequent to the
commencement of the Commitment Period, the Company undertakes to notify the
Investor as to its reasonable expectations as to the dollar amount it intends to
raise during such calendar quarter, if any, through the issuance of Put Notices.
Such notification shall constitute only the Company's good faith estimate with
respect to such calendar quarter and shall in no way obligate the Company to
raise such amount during such calendar quarter or otherwise limit its ability to
deliver Put Notices during such calendar quarter. The failure by the Company to
comply with this provision can be cured by the Company's notifying the Investor
at any time as to its reasonable expectations with respect to the current
calendar quarter.

     Section 6.10  Consolidation; Merger.  The Company shall not, at any time
after the date hereof, effect any merger or consolidation of the Company with or

securities to one or more investors through private placements, except in
connection with strategic partnership or joint venture arrangements.

     Section 6.15  Retention of Financial Services of Hambrecht & Quist.  In the
event the Company desires to retain Hambrecht and Quist Group or any of its
wholly-owned subsidiaries ("H&Q") for additional financial services, and to the
extent the Company's retention of H&Q would potentially restrict the Investor's
resale of the Put Shares or Common Stock issuable upon conversion thereof, the
retention of H&Q must be approved by the Investor. If H&Q is retained by the
Company as an underwriter in a follow-on offering of the Company's securities,
and as a result, the Investor is required to modify the terms of the Warrant and
other compensation received by the Investor from the Company, to comply with the
NASD's prohibitions on excess

     9.9% of all of such Common Stock as would be outstanding on such Closing
     Date, as determined in accordance with Section 16 of the Exchange Act and
     the regulations promulgated thereunder. For purposes of this Section, in
     the event that the amount of Common Stock outstanding as determined in
     accordance with Section 16 of the Exchange Act and the regulations
     promulgated thereunder is greater on a Closing Date than on the date upon
     which the Put Notice associated with such Closing Date is given, the amount
     of Common Stock outstanding on such Closing Date shall govern for purposes
     of determining whether the Investor, when aggregating all purchases of
     Common Stock made pursuant to this Agreement and, if any, Warrant Shares
     and Blackout Shares, would own more than 9.9% of the Common Stock following
     such Closing Date.

          (i)  No Knowledge.  The Company shall have no knowledge of any event
     more likely than not to have the effect of causing such Registration
     Statement to be suspended or otherwise ineffective (which event is more
     likely than not to occur within the fifteen Trading Days following the
     Trading Day on which such Notice is deemed delivered).

          (j)  Shareholder Vote.  The issuance of Put Shares with respect to the
     applicable Closing, if any, shall not violate the shareholder approval
     requirements of the Principal Market.

          (k)  Other.  On each Condition Satisfaction Date, the Investor shall
     have received and been reasonably satisfied with such other certificates
     and documents as shall have been reasonably requested by the Investor in
     order for the Investor to confirm the Company's satisfaction of the
     conditions set forth in this Section 7.2, including, without limitation, a
     certificate in substantially the form and substance of Exhibit F hereto,
     executed in either case by an executive officer of the Company and to the
     effect that all the conditions to such Closing shall have been satisfied as
     at the date of each such certificate.

     Section 7.3  Due Diligence Review.  The Company shall make available for
inspection and review by the Investor, advisors to and representatives of the
Investor, any Registration Statement or amendment or supplement thereto or any
blue sky, NASD or other filing, all financial and other records, all SEC
Documents and other filings with the SEC, and all other corporate documents and
properties of the Company as may be reasonably necessary for the purpose of such
review, and cause the Company's officers, directors and employees to supply all
such information reasonably requested by the Investor or any such representative
or advisor in connection with such Registration Statement (including, without
limitation, in response to all questions and other inquiries reasonably made or
submitted by any of them), prior to and from time to time after the filing and
effectiveness of the Registration Statement for the sole purpose of enabling the
Investor and such representatives and advisors and their respective accountants
and attorneys to conduct initial and ongoing due diligence with respect to the
Company and the accuracy of the Registration Statement.

                                  ARTICLE VIII
                                    LEGENDS

     Section 8.1  Legends.  Each of the Warrant and, unless otherwise provided
below, each certificate representing Registrable Securities will bear the
following legend (the "Legend"):

          THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"),
     OR ANY OTHER APPLICABLE SECURITIES LAWS AND HAVE BEEN ISSUED IN RELIANCE
     UPON AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT
     AND SUCH OTHER SECURITIES LAWS. NEITHER THIS SECURITY NOR ANY INTEREST OR
     PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED,
     PLEDGED, ENCUMBERED, HYPOTHECATED OR OTHERWISE DISPOSED OF, EXCEPT PURSUANT
     TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT
     TO A TRANSACTION THAT IS EXEMPT FROM, OR NOT SUBJECT TO, SUCH REGISTRATION.
     THE HOLDER OF THIS CERTIFICATE IS THE BENEFICIARY OF CERTAIN OBLIGATIONS OF
     THE COMPANY SET FORTH IN A PRIVATE EQUITY LINE OF CREDIT AGREEMENT BETWEEN
     UOL PUBLISHING, INC. AND HAMBRECHT & QUIST GUARANTY FINANCE, LLC DATED AS
     OF MAY           , 1999. A COPY OF THE PORTION OF THE AFORESAID AGREEMENT
     EVIDENCING SUCH OBLIGATIONS MAY BE OBTAINED FROM THE COMPANY'S EXECUTIVE
     OFFICES.

     As soon as practicable after the execution and delivery hereof, but in any
event within 5 Trading Days hereafter, the Company shall issue to the transfer
agent for its Common Stock (and to any substitute or replacement transfer agent
for its Common Stock upon the Company's appointment of any such substitute or
replacement transfer agent) instructions in substantially the form of Exhibit G
hereto, with a copy to the Investor. Such instructions shall be irrevocable by
the Company from and after the date hereof or from and after the issuance
thereof to any such substitute or replacement transfer agent, as the case may
be, except as otherwise expressly provided in the Registration Rights Agreement.
It is the intent and purpose of such instructions, as provided therein, to
require the transfer agent for the Common Stock from time to time upon transfer
of Registrable Securities by the Investor to issue certificates evidencing such
Registrable Securities free of the Legend during the following periods and under
the following circumstances and without consultation by the transfer agent with
the Company or its counsel and without the need for any further advice or
instruction or documentation to the transfer agent by or from the Company or its
counsel or the Investor:

          (a) At any time after the Effective Date, upon surrender of one or
     more certificates evidencing the Put Shares that bear the Legend, to the
     extent accompanied by a notice requesting the issuance of new certificates
     free of the Legend to replace those surrendered; provided that (i) the
     Registration Statement shall then be effective and (ii) if reasonably
     requested by the transfer agent the Investor confirms to the transfer agent
     that the Investor has complied with the prospectus delivery requirement.

                                      A-13
<PAGE>   39

          (b) At any time upon any surrender of one or more certificates
     evidencing Registrable Securities that bear the Legend, to the extent
     accompanied by a notice requesting the issuance of new certificates free of
     the Legend to replace those surrendered and containing representations that
     (i) the Investor is permitted to dispose of such Registrable Securities
     without limitation as to amount or manner of sale pursuant to Rule 144(k)
     under the Securities Act or (ii) the Investor has sold, pledged or
     otherwise transferred or agreed to sell, pledge or otherwise transfer such
     Registrable Securities in a manner other than pursuant to an effective
     registration statement, to a transferee who shall upon such transfer be
     entitled to freely tradable securities.

     Section 8.2  No Other Legend or Stock Transfer Restrictions.  No legend
other than the one specified in Section 8.1 has been or shall be placed on the
share certificates representing the Put Shares and no instructions or "stop
transfers orders," so called, "stock transfer restrictions," or other
restrictions have been or shall be given to the Company's transfer agent with
respect thereto other than as expressly set forth in this Article VIII.

     Section 8.3  Investor's Compliance.  Nothing in this Article VIII shall
affect in any way the Investor's obligations under any agreement to comply with
all applicable securities laws upon resale of the securities issuable hereunder.

                                   ARTICLE IX
                                INDEMNIFICATION

     Section 9.1  Indemnification.  (i) The Company agrees to indemnify and hold
harmless the Investor, its partners, affiliates, officers, directors, employees,
and duly authorized agents, and each Person or entity, if any, who controls the
Investor within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act, together with the Controlling Persons (as defined in the
Registration Rights Agreement) from and against any Damages, joint or several,
and any action in respect thereof to which the Investor, its partners,
affiliates, officers, directors, employees, and duly authorized agents, and any
such Controlling Person becomes subject to, resulting from, arising out of or
relating to any misrepresentation, breach of warranty or nonfulfillment of or
failure to perform any covenant or agreement on the part of Company contained in
this Agreement, as such Damages are incurred, except to the extent that such
damages result from the Investor's failure to perform any covenant or agreement
contained in this Agreement, provided, however, that the Company shall not be
liable in any such case to the extent that any such Damages arise out of or are
based upon information furnished to the Company by or on behalf of the Investor
in writing.

     Section 9.2  Method of Asserting Indemnification Claims.  All claims for
indemnification by any Indemnified Party (as defined below) under Section 9.1
shall be asserted and resolved as follows:

          (a) In the event any claim or demand in respect of which any person
     claiming indemnification under any provision of Section 9.1 (an
     "Indemnified Party") might seek indemnity under Section 9.1 is asserted
     against or sought to be collected from such Indemnified Party by a person
     other than the Company, the Investor or any affiliate of the Company or (a
     "Third Party Claim"), the Indemnified Party shall deliver a written
     notification, enclosing a copy of all papers served, if any, and specifying
     the nature of and basis for such Third Party Claim and for the Indemnified
     Party's claim for indemnification against any person (the "Indemnifying
     Party"), together with the amount or, if not then reasonably ascertainable,
     the estimated amount, determined in good faith, of such Third Party Claim
     (a "Claim Notice") with reasonable promptness to the Indemnifying Party. If
     the Indemnified Party fails to provide the Claim Notice with reasonable
     promptness after the Indemnified Party receives notice of such Third Party
     Claim, the Indemnifying Party shall not be obligated to indemnify the
     Indemnified Party with respect to such Third Party Claim to the extent that
     the Indemnifying Party's ability to defend has been materially prejudiced
     by such failure of the Indemnified Party. The Indemnifying Party shall
     notify the Indemnified Party as soon as practicable within the period
     ending fifteen (15) calendar days following receipt by the Indemnifying
     Party of either a Claim Notice or an Indemnity Notice (as defined below)
     (the "Dispute Period") whether the Indemnifying Party disputes its
     liability or the amount of its liability

                                      A-14
<PAGE>   40

     to the Indemnified Party under Section 9.1 and whether the Indemnifying
     Party desires, at its sole cost and expense, to defend the Indemnified
     Party against such Third Party Claim.

             (i) If the Indemnifying Party notifies the Indemnified Party within
        the Dispute Period that the Indemnifying Party desires to defend the
        Indemnified Party with respect to the Third Party Claim pursuant to this
        Section 9.2(a), then the Indemnifying Party shall have the right to
        defend, with counsel reasonably satisfactory to the Indemnified Party,
        at the sole cost and expense of the Indemnifying Party, such Third Party
        Claim by all appropriate proceedings, which proceedings shall be
        vigorously and diligently prosecuted by the Indemnifying Party to a
        final conclusion or will be settled at the discretion of the
        Indemnifying Party (but only with the consent of the Indemnified Party
        in the case of any settlement that provides for any relief other than
        the payment of monetary damages or that provides for the payment of
        monetary damages as to which the Indemnified Party shall not be
        indemnified in full pursuant to Section 9.1). The Indemnifying Party
        shall have full control of such defense and proceedings, including any
        compromise or settlement thereof; provided, however, that the
        Indemnified Party may at any time prior to the Indemnifying Party's
        delivery of the notice referred to in the first sentence of this clause
        (i), file any motion, answer or other pleadings or take any other action
        that the Indemnified Party reasonably believes to be necessary or
        appropriate to protect its interests at the expense of the Indemnifying
        Party; and provided further, that if requested by the Indemnifying
        Party, the Indemnified Party will, at the sole cost and expense of the
        Indemnifying Party, provide reasonable cooperation to the Indemnifying
        Party in contesting any Third Party Claim that the Indemnifying Party
        elects to contest. The Indemnified Party may participate in, but not
        control, any defense or settlement of any Third Party Claim controlled
        by the Indemnifying Party pursuant to this clause (i), and shall bear
        its own costs and expenses with respect to such participation unless, in
        the reasonable judgment of counsel to the Indemnified Party the
        Indemnified Party shall have defenses to the Third Party Claim in
        addition to or different from the defenses available to the Indemnifying
        Party, in which case the costs and expenses of the Indemnified Party's
        participation shall be paid by the Indemnifying Party. Notwithstanding
        the foregoing, the Indemnified Party may take over the control of the
        defense or settlement of a Third Party Claim at any time if it
        irrevocably waives its right to indemnity under Section 9.1 with respect
        to such Third Party Claim.

             (ii) If the Indemnifying Party fails to notify the Indemnified
        Party within the Dispute Period that the Indemnifying Party desires to
        defend the Third Party Claim pursuant to Section 9.2(a), or if the
        Indemnifying Party gives such notice but fails to prosecute vigorously
        and diligently or settle the Third Party Claim, then the Indemnified
        Party shall have the right to defend, at the sole cost and expense of
        the Indemnifying Party, the Third Party Claim by all appropriate
        proceedings, which proceedings shall be prosecuted by the Indemnified
        Party in a reasonable manner and in good faith or will be settled at the
        discretion of the Indemnified Party (with the consent of the
        Indemnifying Party, which consent will not be unreasonably withheld).
        The Indemnified Party will have full control of such defense and
        proceedings, including any compromise or settlement thereof; provided,
        however, that if requested by the Indemnified Party, the Indemnifying
        Party will, at the sole cost and expense of the Indemnifying Party,
        provide reasonable cooperation to the Indemnified Party and its counsel
        in contesting any Third Party Claim which the Indemnified Party is
        contesting.

          (b) In the event any Indemnified Party should have a claim under
     Section 9.1 against the Indemnifying Party that does not involve a Third
     Party Claim, the Indemnified Party shall deliver to the Indemnifying Party
     a written notification of a claim for indemnity under Section 9.1
     specifying the nature of and basis for such claim, together with the amount
     or, if not then reasonably ascertainable, the estimated amount, determined
     in good faith, of such claim (an "Indemnity Notice") with reasonable
     promptness to the Indemnifying Party. The failure by any Indemnified Party
     to give the Indemnity Notice shall not impair such party's rights hereunder
     except to the extent that the Indemnifying Party has been materially
     prejudiced thereby. If the Indemnifying Party notifies the Indemnified
     Party that it does not dispute the claim or the amount of the claim
     described in such Indemnity Notice or fails to notify the Indemnified Party
     within the Dispute Period whether the Indemnifying Party disputes the claim
     or the

                                      A-15
<PAGE>   41

     amount of the claim described in such Indemnity Notice, the Loss in the
     amount specified in the Indemnity Notice will be conclusively deemed a
     liability of the Indemnifying Party under Section 9.1 and the Indemnifying
     Party shall pay the amount of such Loss to the Indemnified Party on demand.
     If the Indemnifying Party has timely disputed its liability or the amount
     of its liability with respect to such claim, the Indemnifying Party and the
     Indemnified Party shall proceed in good faith to negotiate a resolution of
     such dispute.

                                   ARTICLE X
                                 MISCELLANEOUS

     Section 10.1  Fees and Expenses.  The Company and the Investor agree to pay
their own expenses incident to the performance of their obligations hereunder,
except that the Company shall pay all the reasonable out-of-pocket expenses of
Investor, including expenses of Investor's counsel, incurred in the preparation,
negotiation, execution and delivery of this Agreement, the Registration Rights
Agreement and the Warrant, and in any participation by such counsel in the
preparation of the Registration Statement. In addition, the Company shall pay
the Investor (a) a one-time fee of $30,000 payable on the Subscription Date, and
(b) a quarterly fee equal to .002 times the maximum aggregate consideration
still available after giving effect to all limitations contained in this
Agreement on the Company's right to Put Shares to the Investor, including,
without limitation, Section 7.2(h) hereof, if any, for purchase of Put Shares
under this Agreement (the "Unused Commitment") on the 90th day after the
Subscription Date, and (iii) a prorated fee on the day following the end of the
Commitment Period equal to the Unused Commitment as of such date times .002
times the number of days after such 90th day until the end of the Commitment
Period divided by 90.

     Section 10.2  Brokerage.  Each of the parties hereto represents that,
except as set forth in Section 10.1, it has had no dealings in connection with
this transaction with any finder or broker who will demand payment of any fee or
commission from the other party. The Company on the one hand, and the Investor,
on the other hand, agree to indemnify the other against and hold the other
harmless from any and all liabilities to any persons claiming brokerage
commissions or finder's fees on account of services purported to have been
rendered on behalf of the indemnifying party in connection with this Agreement
or the transactions contemplated hereby.

right or remedy in the future.

     Section 10.6  Annexes and Exhibits; Entire Agreement.  All annexes and

Agreement becomes or is declared by a court of competent jurisdiction to be
illegal, unenforceable or void, this Agreement shall continue in full force and

expressly vested in the Board of Directors of the Corporation by the Certificate
of Incorporation, as amended, the Board of Directors duly adopted the following
resolutions:

     RESOLVED, that, pursuant to the Certificate of Incorporation, as amended,
of the Corporation (the "Amended Certificate of Incorporation"), which
authorizes 10,000,000 shares of undesignated preferred stock, par value $0.01

which are designated Series D Convertible Preferred Stock, par value $0.01 per
share, (the "Series D Preferred Stock") 1,082,625 of which are currently issued
and outstanding, the Board of Directors is authorized, within the limitations
and restrictions stated in the Amended Certificate of Incorporation, to fix by
resolution or resolutions the designation of each series of preferred stock and
the powers, preferences and relative participating, optional, or other special
rights, and qualifications, limitations, and restrictions thereof; and

     RESOLVED, that the Corporation hereby fixes the designations and
preferences and relative, participating, optional, and other special rights, and
qualifications, limitations, and restrictions of the preferred stock consisting
of 3,000,000 shares to be designated Series E Convertible Preferred Stock, par
value $0.01 per share, to be issued in consecutively numbered subseries
beginning with Subseries E-1 (collectively, the "Series E Preferred Stock"); and

     RESOLVED, that the Series E Preferred Stock is hereby authorized on the
terms and with the provisions herein set forth:

II. PROVISIONS RELATING TO THE PREFERRED STOCK.

     1.  Rank.  The Series E Preferred Stock shall, with respect to dividend
rights and with respect to rights upon liquidation, winding up or dissolution,
rank pari passu to the Series C Preferred Stock and the Series D Preferred Stock
and senior and prior in right to (a) each class of common stock of the
Corporation ("Common Stock"), (b) any series of preferred stock either
previously or hereafter created (except Series C and Series D Preferred Stock)
and (c) any other equity interests (including, without limitation, warrants,
stock appreciation rights, phantom stock rights, profit participation rights in
debt instruments or other rights with equity features, calls or options
exercisable for or convertible into such capital stock or equity interests) in
the Corporation that by its terms rank junior to the Series E Preferred Stock
(all of such classes or series of capital stock and other equity interests,
including, without limitation, all classes of Common Stock of the Corporation,
are collectively referred to as "Junior Securities").

     2.  Dividends.  (a) The holders of Series E Preferred Stock shall be
entitled to receive a 6% annual dividend, payable on the last day of each
calendar month in Series E Preferred Stock at 85% of the closing price of the
Common Stock on the principal market or exchange therefor on the date of payment
of the dividend.

     (b) So long as any shares of Series E Preferred Stock are outstanding, the
Corporation will not declare, pay or set apart for payment any dividends (except
dividends payable on the Series C, D and E Preferred

                                       B-1
<PAGE>   45

Stock or dividends payable in Common Stock of the Corporation) or make any other
distribution on or redeem, purchase or otherwise acquire any Junior Securities
and will not permit any Subsidiary or other Affiliate (as defined in Section 6)
to use funds of the Corporation or any Subsidiary to redeem, purchase or
otherwise acquire for value, any Junior Securities. Notwithstanding the
foregoing provisions of this Section 2(b), the Corporation or any Subsidiary may
(i) make payments in respect of fractional shares of Junior Securities and (ii)
repurchase, redeem or otherwise acquire for value any Junior Securities from any
employee or former employee of the Corporation or any Subsidiary in connection
with the termination of employment by the Corporation or any Subsidiary or by
such employee or former employee, whether by reason of death, disability,
retirement or otherwise.

     3.  Liquidation.  Upon a change in control pursuant to which the
stockholders of the Corporation immediately prior to such change in control
possess a minority of the voting power of the acquiring entity immediately
following such change in control, liquidation, dissolution or winding up of the
affairs of the Corporation, whether voluntary or involuntary (a "Liquidation
Event"), the holders of the Series E Preferred Stock shall be entitled, pari
passu with the liquidation preference payable to the holders of the Series C and
D Preferred Stock (respectively, the "Series C Liquidation Preference" and the
"Series D Liquidation Preference"), before any assets of the Corporation shall
be distributed among or paid over to the holders of Junior Securities, to
receive from the assets of the Corporation available for distribution to
stockholders, an amount per share equal to for each successively numbered
subseries of the Series E Preferred Stock, the per share price paid for any
subseries of the Series E Preferred Stock pursuant to that Private Equity Line
of Credit Agreement dated May 4, 1999 entered into between the Corporation and
Hambrecht & Quist Guaranty Finance, LLC, as adjusted to reflect any and all
subdivisions (by stock split, stock dividend or otherwise) or combinations or
consolidations (by reclassification or otherwise) of the Series E Preferred
Stock occurring after the Issue Date (as defined in Section 6) of any subseries
of Series E Preferred Stock plus all declared but unpaid dividends (as adjusted,
the "Series E Liquidation Preference"). If the assets of the Corporation legally
available for distribution shall be insufficient to permit the payment in full
to the holders of the Series C Preferred Stock, the Series D Preferred Stock and
the Series E Preferred Stock of the Series C, Series D and Series E Liquidation
Preferences, then the entire assets of the Corporation legally available for
distribution shall be distributed ratably in accordance with the Series C,
Series D and E Liquidation Preferences among such holders. For purposes of this
Section 3, a Liquidation Event shall be deemed to be occasioned by, and to
include, (i) the Corporation's sale of all or substantially all of its assets or
capital stock or (ii) any transaction or series or related transactions
(including, without limitation, any reorganization, merger or consolidation)
that will result in the holders of the outstanding voting equity securities of
the Corporation immediately prior to such transaction or series of related
transactions holding securities representing less than forty percent (40%) of
the voting power of the surviving entity immediately following such transaction
or series of related transactions.

     4.  Voting.  (a) Except as otherwise provided by law or by subsection 4(b),
the holders of the Series E Preferred Stock shall be entitled to vote on all
matters submitted to the stockholders for a vote together with the holders of
the Common Stock voting together as a single class, with each holder of Common
Stock entitled to one vote for each share of Common Stock held by such holder
and each holder of Series E Preferred Stock entitled to one vote for each share
of Series E Preferred Stock held by such holder at the time the vote is taken.

     (b) The holders of the Series E Preferred Stock shall vote as a separate
class on the creation of any new series of preferred stock or the issuance of
additional shares of capital stock of the Corporation that ranks senior to or on
a parity with the Series E Preferred Stock.

     5. Conversion of Series E Preferred Stock into Common Stock.

          (a) Conversion Procedure.

             (i) At any time, any holder of Series E Preferred Stock may convert
        all or any portion of the Series E Preferred Stock held by such holder
        into a number of shares of Conversion Stock (as defined in Section 6)
        computed by multiplying the number of shares to be converted by the
        purchase

                                       B-2
<PAGE>   46

        price thereof and dividing the result by the Conversion Price (as
        defined in subsection 5(b) then in effect.

             (ii) Each conversion of Series E Preferred Stock shall be deemed to
        have been effected as of the close of business on the date on which
        notice of election of such conversion is delivered to the Corporation by
        such holder. Until the certificates representing the shares of Series E
        Preferred Stock which are being converted have been surrendered and new
        certificates representing shares of the Conversion Stock shall have been
        issued by the Corporation, such certificate(s) evidencing the shares of
        Series E Preferred Stock being converted shall be evidence of the
        issuance of such shares of Conversion Stock. At such time as such
        conversion has been effected, the rights of the holder of such Series E
        Preferred Stock as such holder shall cease and the Person or Persons in
        whose name or names any certificate or certificates for shares of
        Conversion Stock are to be issued upon such conversion shall be deemed
        to have become the holder or holders of record of the shares of
        Conversion Stock represented thereby.

             (iii) Notwithstanding any other provision hereof, if a conversion
        of shares is to be made in connection with a Public Offering (as defined
        in Section 6), the conversion of such shares may, at the election of the
        holder thereof, be conditioned upon the consummation of the Public
        Offering, in which case such conversion shall not be deemed to be
        effective until the consummation of the Public Offering.

             (iv) As soon as practicable after a conversion has been effected in
        accordance with clause (ii) above, the Corporation shall deliver to the
        converting holder: (A) a certificate or certificates representing, in
        the aggregate, the number of shares of Conversion Stock issuable by
        reason of such conversion, in the name or names and in such denomination
        or denominations as the converting holder has specified; and (B) a
        certificate representing any shares which were represented by the
        certificate or certificates delivered to the Corporation in connection
        with such conversion but which were not converted.

             (v) The issuance of certificates for shares of Conversion Stock
        upon conversion of Series E Preferred Stock shall be made without charge
        to the holders of such Series E Preferred Stock for any issuance tax in
        respect thereof or other cost incurred by the Corporation in connection
        with such conversion and the related issuance of shares of Conversion
        Stock, except for any transfer or similar tax payable as a result of
        issuance of a certificate to other than the registered holder of the
        shares being converted. Upon conversion of any shares of Series E
        Preferred Stock, the Corporation shall use its best efforts to take all
        such actions as are necessary in order to insure that the Conversion
        Stock issuable with respect to such conversion shall be validly issued,
        fully paid and nonassessable.

             (vi) The Corporation shall not close its books against the transfer
        of Series E Preferred Stock or of Conversion Stock issued or issuable
        upon conversion of Series E Preferred Stock in any manner which
        interferes with the timely conversion of Series E Preferred Stock. The
        Corporation shall assist and cooperate with any holder of shares of
        Series E Preferred Stock required to make any governmental filings or
        obtain any governmental approval prior to or in connection with any
        conversion of shares hereunder (including, without limitation, making
        any filings reasonably required to be made by the Corporation).

             (vii) No fractional shares of Conversion Stock or scrip
        representing fractional shares shall be issued upon conversion of shares
        of Series E Preferred Stock. If more than one share of Series E
        Preferred Stock shall be surrendered for conversion at one time by the
        same record holder, the number of full shares of Conversion Stock
        issuable upon the conversion thereof shall be computed on the basis of
        the aggregate number of shares of Series E Preferred Stock so
        surrendered by such record holder. Instead of any fractional share of
        Conversion Stock otherwise issuable upon conversion of any shares of the
        Series E Preferred Stock, the Corporation shall pay a cash adjustment in
        respect of such fraction in an amount equal to the same fraction of
        current per share fair market value of the Conversion Stock as
        determined in good faith by the Board of Directors on such basis as it
        considers appropriate.

                                       B-3
<PAGE>   47

             (viii) The Corporation shall use its best efforts at all times to
        reserve and keep available out of its authorized but unissued shares of
        Conversion Stock, solely for the purpose of issuance upon the conversion
        of the Series E Preferred Stock, such number of shares of Conversion
        Stock as are issuable upon the conversion of all outstanding Series E
        Preferred Stock. All shares of Conversion Stock which are so issuable
        shall, when issued, be duly and validly issued, fully paid and
        nonassessable and free from all taxes, liens and charges, other than
        those created or agreed to by the holder. The Corporation shall use its
        best efforts to take all such actions as may be necessary to assure that
        all such shares of Conversion Stock may be so issued without violation
        of any applicable law or governmental regulation or any requirements of
        any domestic securities exchange upon which shares of Conversion Stock
        may be listed (except for official notice of issuance which shall be
        immediately delivered by the Corporation upon each such issuance).

          (b) Conversion Price.

             (i) "Conversion Price" for the Series E Preferred Stock shall
        initially mean the Initial Conversion Price described in this Section 5,
        as the same may be subsequently adjusted from time to time in accordance
        with this Section 5.

             (ii) The "Initial Conversion Price" shall be the Liquidation
        Preference of each subseries of Series E Preferred Stock.

          (c) Subdivision or Combination of Common Stock.  If the Corporation at
     any time subdivides (by any stock split, stock dividend, recapitalization
     or otherwise) one or more classes of its outstanding shares of Common Stock
     into a greater number of shares, or if the Corporation at any time combines
     (by reverse stock split or otherwise) one or more classes of its
     outstanding shares of Common Stock into a smaller number of shares, the
     applicable Conversion Price in effect immediately prior to such subdivision
     or combination shall be proportionately adjusted.

          (d) Consolidation, Merger or Sale for Assets.  Any consolidation,
     merger, sale of all or substantially all of the Corporation's assets to
     another Person or other transaction which is effected in such a manner that
     holders of Common Stock are entitled to receive (either directly or upon
     subsequent liquidation) assets other than Conversion Stock ("Sale
     Consideration") with respect to or in exchange for Common Stock is referred
     to herein as an "Fundamental Change." Prior to the consummation of any
     Fundamental Change, the Corporation shall make appropriate provisions to
     insure that each of the holders of Series E Preferred Stock shall
     thereafter have the right to acquire and receive, in lieu of or in addition
     to (as the case may be) the shares of Conversion Stock immediately
     theretofore acquirable and receivable upon the conversion of such holder's
     Series E Preferred Stock, such Sale Consideration as such holder would have
     received in connection with such Fundamental Change if such holder had
     converted its Series E Preferred Stock into Conversion Stock immediately
     prior to such Fundamental Change. The Corporation shall not effect any
     Fundamental Change, consolidation, merger or sale unless prior to the
     consummation thereof, the successor corporation (if other than the
     Corporation) resulting from consolidation or merger or the corporation
     purchasing such assets assumes by written instrument the obligation to
     deliver to each such holder such shares of stock, securities or assets as,
     in accordance with the foregoing provisions, such holder may be entitled to
     acquire.

          (e) Certain Events.  If an event not specifically enumerated in this
     Section 5 occurs which has substantially the same economic effect on the
     Series E Preferred Stock as those specifically enumerated shall occur, then
     this Section 5 shall be construed liberally, mutatis mutandis, in order to
     give the Series E Preferred Stock the benefit of the protections provided
     under this Section 5. The Board of Directors shall make an appropriate
     adjustment in the applicable Conversion Price so as to protect the rights
     of the holders of Series E Preferred Stock.

          (f) Notices.

             (i) Promptly upon any adjustment of the applicable Conversion
        Price, the Corporation shall give written notice thereof to all holders
        of Series E Preferred Stock, setting forth in reasonable detail and
        certifying the calculation of such adjustment.

                                       B-4
<PAGE>   48

             (ii) The Corporation shall give written notice to all holders of
        Series E Preferred Stock at least 10 days prior to the date on which the
        Corporation closes its books or takes a record (A) with respect to any
        dividend or distribution upon Common Stock, (B) with respect to any pro
        rata subscription offer to holders of Common Stock, or (C) for
        determining rights to vote with respect to any Fundamental Change,
        dissolution or liquidation.

             (iii) The Corporation shall give written notice to the holders of
        Series E Preferred Stock at least twenty (20) days prior to the date on
        which any Fundamental Change shall take place, which notice may be one
        and the same as that required by (ii) above.

                                   ARTICLE IV
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     The Company represents and Warrants to the Investors that, except as set
forth on the Disclosure Schedule prepared by the Company and delivered herewith:

     Section 4.1.  Organization of the Company.  The Company is a corporation
duly incorporated and existing in good standing under the laws of the State of
Delaware and has all requisite corporate authority to own its properties and to
carry on its business as now being conducted. The Company does not have any
subsidiaries and does not own more that fifty percent (50%) of or control any
other business entity except as set forth in the SEC Documents. The Company is
duly qualified and is in good standing as a foreign corporation to do business
in every jurisdiction in which the nature of the business conducted or property
owned by it makes such qualification necessary, other than those in which the
failure so to qualify would not have a Material Adverse Effect.

     Section 4.2.  Authority.  (i) The Company has the requisite corporate power
and corporate authority to enter into and perform its obligations under this
Agreement, the Security Agreement, the Registration Rights Agreement, the Escrow
Agreement, and the Warrants and to issue the Convertible Debentures, the
Conversion Shares, the Warrants and the Warrant Shares pursuant to their
respective terms, (ii) the execution, issuance and delivery of this Agreement,
the Security Agreement, the Registration Rights Agreement, the Escrow Agreement,
the Convertible Debenture certificates and the Warrants by the Company and the
consummation by it of the transactions contemplated hereby have been duly
authorized by all necessary corporate action and no further consent or
authorization of the Company or its Board of Directors or stockholders is
required, and (iii) this Agreement, the Security Agreement, the Registration
Rights Agreement, the Escrow Agreement, the Convertible Debenture certificates
and the Warrants have been duly executed and delivered by the Company and at the
Closing shall constitute valid and binding obligations of the Company
enforceable against the Company in accordance with their terms, except as such
enforceability may be limited by applicable bankruptcy, insolvency, or similar
laws relating to, or affecting generally the enforcement of, creditors' rights
and remedies or by other equitable principles of general application. The
Company has duly and validly authorized and reserved for issuance shares of
Common Stock sufficient in number for the conversion of the Convertible
Debentures and for the exercise of the Warrants. The Company understands and
acknowledges the potentially dilutive effect to the Common Stock of the issuance
of the Conversion Shares. The Company further acknowledges that its obligation
to issue Conversion Shares upon conversion of the Convertible Debentures and
Warrant Shares upon exercise of the Warrants in accordance with this Agreement
is absolute and unconditional regardless of the dilutive effect that such
issuance may have on the ownership interests of other stockholders of the
Company and notwithstanding the commencement of any case under 11 U.S.C. sec.
101 et seq. (the "Bankruptcy Code"). The Company shall not seek judicial relief
from its obligations hereunder except pursuant to the Bankruptcy Code. In the
event the Company is a debtor under the Bankruptcy Code, the Company hereby
waives to the fullest extent permitted any rights to relief it may have under 11
U.S.C. sec. 362 in respect of the conversion of the Convertible Debentures and
the exercise of the Warrants. The Company agrees, without cost or expense to the
Investors, to take or consent to any and all action necessary to effectuate
relief under 11 U.S.C. sec. 362.

     Section 4.3.  Capitalization.  The authorized capital stock of the Company
consists of 36,000,000 shares of Common Stock, $0.01 par value per share, of
which 4,754,061 shares were issued and outstanding as of June 1, 1999 and
10,000,000 shares of preferred stock, par value $0.01 per share, of which
1,000,000 have been designated as Series C Convertible Preferred Stock, of which
626,293 were issued and outstanding as of June 1, 1999 and 1,200,000 have been
designated as Series D Convertible Preferred Stock, of which 1,082,625 were
issued and outstanding as of June 1, 1999. Except for (i) the outstanding Series
C and Series D Convertible Preferred Stock and (ii) outstanding options and
warrants as set forth in the SEC Documents, there are no outstanding Capital
Shares Equivalents nor any agreements or understandings
                                       C-6
<PAGE>   56

pursuant to which any Capital Shares Equivalents may become outstanding. The
Company is not a party to any agreement granting registration or anti-dilution
rights to any person with respect to any of its equity or debt securities. All
of the outstanding shares of Common Stock of the Company have been duly and
validly authorized and issued and are fully paid and non-assessable.

     Section 4.4.  Common Stock.  The Company has registered its Common Stock
pursuant to Section 12(b) or (g) of the Exchange Act and is in full compliance
with all reporting requirements of the Exchange Act, and the Company is in
compliance with all requirements for the continued listing or quotation of its
Common Stock, and such Common Stock is currently listed or quoted on, the
Principal Market. As of the date hereof, the Principal Market is the Nasdaq
SmallCap Market and the Company has not received any notice regarding, and to
its knowledge there is no threat of, the termination or discontinuance of the
eligibility of the Common Stock for such listing.

     Section 4.5.  SEC Documents.  The Company has made available to the
Investors true and complete copies of the SEC Documents. The Company has not
provided to the Investors any information that, according to applicable law,
rule or regulation, should have been disclosed publicly prior to the date hereof
by the Company, but which has not been so disclosed. As of their respective
dates, the SEC Documents (a) complied in all material respects with the
requirements of the Exchange Act, and rules and regulations of the SEC
promulgated thereunder, and (b) did not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading. The financial statements of the
Company included in the SEC Documents complied in all material respects with
applicable accounting requirements and the published rules and regulations of
the SEC or other applicable rules and regulations with respect thereto at the
time of such inclusion. Such financial statements have been prepared in
accordance with generally accepted accounting principles applied on a consistent
basis during the periods involved (except (i) as may be otherwise indicated in
such financial statements or the notes thereto or (ii) in the case of unaudited
interim statements, to the extent they exclude footnotes or may be condensed or
summary statements) and fairly present in all material respects the financial
position of the Company as of the dates thereof and the results of operations
and cash flows for the periods then ended (subject, in the case of unaudited
interim statements, to normal year-end audit adjustments). Neither the Company
nor any of its subsidiaries has any material indebtedness, obligations or
liabilities of any kind (whether accrued, absolute, contingent or otherwise, and
whether due or to become due) that would have been required to be reflected in,
reserved against or otherwise described in the financial statements or in the
notes thereto in accordance with GAAP, which was not fully reflected in,
reserved against or otherwise described in the financial statements or the notes
thereto included in the SEC Documents or was not incurred in the ordinary course
of business consistent with the Company's past practices since the last date of
such financial statements.

     Section 4.6.  Exemption from Registration; Valid Issuances.  Subject to the
accuracy of the Investors' representations in Article III, the sale of the
Convertible Debentures, the Conversion Shares, the Warrants and the Warrant
Shares will not require registration under the Securities Act and/or any
applicable state securities law. When issued and paid for in accordance with the
Warrants and validly converted in accordance with the terms of the Convertible
Debentures, the Conversion Shares and the Warrant Shares will be duly and
validly issued, fully paid, and non-assessable. Neither the sales of the
Convertible Debentures, the Conversion Shares, the Warrants or the Warrant
Shares pursuant to, nor the Company's performance of its obligations under, this
Agreement, the Registration Rights Agreement, the Escrow Agreement, the
Convertible Debentures or the Warrants will (i) result in the creation or
imposition by the Company of any liens, charges, claims or other encumbrances
upon the Convertible Debentures, the Conversion Shares, the Warrants or the
Warrant Shares or, except as contemplated herein, any of the assets of the
Company, or (ii) entitle the holders of Outstanding Capital Shares to preemptive
or other rights to subscribe for or acquire the Capital Shares or other
securities of the Company. The Convertible Debentures, the Conversion Shares,
the Warrants and the Warrant Shares shall not subject the Investors to personal
liability to the Company or its creditors by reason of the possession thereof.

     Section 4.7.  No General Solicitation or Advertising in Regard to this
Transaction.  Neither the Company nor any of its affiliates nor, to the
knowledge of the Company, any person acting on its or their
                                       C-7
<PAGE>   57

behalf (i) has conducted or will conduct any general solicitation (as that term
is used in Rule 502(c) of Regulation D) or general advertising with respect to
the sale of the Convertible Debentures or the Warrants, or (ii) made any offers
or sales of any security or solicited any offers to buy any security under any
circumstances that would require registration of the sale of the Convertible
Debentures, the Conversion Shares, the Warrants or the Warrant Shares under the
Securities Act.

     Section 4.8.  No Conflicts.  The execution, delivery and performance of
this Agreement by the Company and the consummation by the Company of the
transactions contemplated hereby, including without limitation the issuance of
and payment of interest upon the Convertible Debentures, the Conversion Shares,
the Warrants and the Warrant Shares, and the grant of the security interest
created by the Security Agreement, do not and will not (i) result in a violation
of the Company's Certificate of Incorporation or By-Laws or (ii) conflict with,
or constitute a material default (or an event that with notice or lapse of time
or both would become a default) under, or give to others any rights of
termination, amendment, acceleration or cancellation of, any material agreement,
indenture or instrument, or any "lock-up" or similar provision of any
underwriting or similar agreement to which the Company is a party, or (iii)
result in a violation of any federal, state or local law, rule, regulation,
order, judgment or decree (including federal and state securities laws and
regulations) applicable to the Company or by which any material property or
asset of the Company is bound or affected, nor is the Company otherwise in
violation of, conflict with or default under any of the foregoing (except in
each case for such conflicts, defaults, terminations, amendments, accelerations,
cancellations and violations as would not have, individually or in the
aggregate, a Material Adverse Effect). The business of the Company is not being
conducted in violation of any law, ordinance or regulation of any governmental
entity, except for possible violations that either singly or in the aggregate
would not have a Material Adverse Effect. The Company is not required under any
Federal, state or local law, rule or regulation to obtain any consent,
authorization or order of, or make any filing or registration with, any court or
governmental agency in order for it to execute, deliver or perform any of its
obligations under this Agreement or issue and sell the Convertible Debentures or
the Warrants in accordance with the terms hereof (other than any SEC, Principal
Market or state securities filings that may be required to be made by the
Company subsequent to Closing, any registration statement that may be filed
pursuant hereto, and any shareholder approval required by the rules applicable
to companies whose common stock trades on the Principal Market); provided that,
for purposes of the representation made in this sentence, the Company is
assuming and relying upon the accuracy of the relevant representations and
agreements of the Investors herein.

     Section 4.9.  No Material Adverse Change.  Since March 31, 1999, no
Material Adverse Effect has occurred or exists with respect to the Company,
except as disclosed in the SEC Documents.

     Section 4.10.  No Undisclosed Events or Circumstances.  Since March 31,
1999, no event or circumstance has occurred or exists with respect to the
Company or its businesses, properties, prospects, operations or financial
condition, that, under applicable law, rule or regulation, requires public
disclosure or announcement prior to the date hereof by the Company but which has
not been so publicly announced or disclosed in the SEC Documents.

     Section 4.11.  No Integrated Offering.  Other than pursuant to an effective
registration statement under the Securities Act, or pursuant to the issuance or
exercise of employee stock options, or pursuant to its discussion with the
Investors in connection with the transactions contemplated hereby, (a) the
Company has not issued, offered or sold the Convertible Debentures, the Warrants
or any shares of Common Stock (including for this purpose any securities of the
same or a similar class as the Convertible Debentures, the Warrants or Common
Stock, or any securities convertible into or exchangeable or exercisable for the
Convertible Debentures or Common Stock or any such other securities) within the
six-month period next preceding the date hereof, and (b) the Company shall not
permit any of its directors, officers or affiliates directly or indirectly to
take, any action (including, without limitation, any offering or sale to any
Person of the Convertible Debentures, Warrants or shares of Common Stock), so as
in either (a) or (b) or both to make unavailable the exemption from Securities
Act registration being relied upon by the Company for the offer and sale to
Investors of the Convertible Debentures (and the Conversion Shares) or the
Warrants (and the Warrant Shares) as contemplated by this Agreement.

the SEC Documents, there are no lawsuits or proceedings pending or, to the
knowledge of the Company, threatened, against the Company or any subsidiary, nor
has the Company received any written or oral notice of any such action, suit,
proceeding or investigation, which could reasonably be expected to have a
Material Adverse Effect. Except as set forth in the SEC Documents, no judgment,
order, writ, injunction or decree or award has been issued by or, to the
knowledge of the Company, requested of any court, arbitrator or governmental
agency which could result in a Material Adverse Effect.

     Section 4.13.  No Misleading or Untrue Communication.  The Company and, to
the knowledge of the Company, any person representing the Company, or any other
person selling or offering to sell the Convertible Debentures or the Warrants in
connection with the transaction contemplated by this Agreement, have not made,
at any time, any oral communication in connection with the offer or sale of the
same which, together with all such communications, including the SEC Documents,
taken as a whole, contained any untrue statement of a material fact or omitted
to state any material fact necessary in order to make the statements, in the
light of the circumstances under which they were made, not misleading.

     Section 4.14.  Material Non-Public Information.  The Company has not
disclosed to the Investors any material non-public information that (i) if
disclosed, would reasonably be expected to have a material effect on the price
of the Common Stock or (ii) according to applicable law, rule or regulation,
should have been disclosed publicly by the Company prior to the date hereof but
which has not been so disclosed.

     Section 4.15.  Insurance.  The Company and each subsidiary maintains
property and casualty, general liability, workers' compensation, environmental
hazard, personal injury and other similar types of insurance with financially
sound and reputable insurers that is adequate, consistent with industry
standards and the Company's historical claims experience. The Company has not
received notice from, and has no knowledge of any threat by, any insurer (that
has issued any insurance policy to the Company) that such insurer intends to
deny coverage under or cancel, discontinue or not renew any insurance policy
presently in force.

     Section 4.16.  Tax Matters.  (a) The Company and each subsidiary has filed
all Tax Returns which it is required to file under applicable laws; all such Tax
Returns are true and accurate in all material respects and have been prepared in
compliance with all applicable laws; the Company has paid all Taxes due and
owing by it or any subsidiary (whether or not such Taxes are required to be
shown on a Tax Return) and have withheld and paid over to the appropriate taxing
authorities all Taxes which it is required to withhold from amounts paid or
owing to any employee, stockholder, creditor or other third parties; and since
December 31, 1998, the charges, accruals and reserves for Taxes with respect to
the Company (including any provisions for deferred income taxes) reflected on
the books of the Company are adequate to cover any Tax liabilities of the
Company if its current tax year were treated as ending on the date hereof.

     (b) No claim has been made by a taxing authority in a jurisdiction where
the Company does not file tax returns that the Company or any subsidiary is or
may be subject to taxation by that jurisdiction. There are no foreign, federal,
state or local tax audits or administrative or judicial proceedings pending or
being conducted with respect to the Company or any subsidiary; no information
related to Tax matters has been requested from the Company by any foreign,
federal, state or local taxing authority; and no written notice indicating an
intent to open an audit or other review has been received by the Company or any
subsidiary from any foreign, federal, state or local taxing authority. There are
no material unresolved questions or claims concerning the Company's Tax
liability. The Company (A) has not executed or entered into a closing agreement
pursuant to sec. 7121 of the Internal Revenue Code or any predecessor provision
thereof or any similar provision of state, local or foreign law; or (B) has not
agreed to or is required to make any adjustments pursuant to sec. 481 (a) of the
Internal Revenue Code or any similar provision of state, local or foreign law by
reason of a change in accounting method initiated by the Company or any of its
subsidiaries or has any knowledge that the IRS has proposed any such adjustment
or change in accounting method, or has any application pending with any taxing
authority requesting permission for any changes in accounting methods that
relate to the business or operations of the Company. The Company has not been a
United States real property holding corporation within the meaning of sec.
897(c)(2) of the Internal Revenue Code during the applicable period specified in
sec. 897(c)(1)(A)(ii) of the Internal Revenue Code.

     (c) The Company has not made an election under sec. 341(f) of the Internal
Revenue Code. The Company is not liable for the Taxes of another person that is
not a subsidiary of the Company (A) under Treas. Reg. sec. 1.1502-6 (or
comparable provisions of state, local or foreign law), (B) as a transferee or
successor, (C) by contract or indemnity or (D) otherwise. The Company is not a
party to any tax sharing agreement. The Company has not made any payments, is
not obligated to make payments nor is the Company a party to an agreement that
could obligate it to make any payments that would not be deductible under sec.
280G of the Internal Revenue Code.

     (d) For purposes of this Section 4.16:

     not.

          "Tax Return" means any return, information report or filing with
     respect to Taxes, including any schedules attached thereto and including

     Section 4.17.  Property.  Neither the Company nor any of its subsidiaries
owns any real property. Each of the Company and its subsidiaries has good and
marketable title to all personal property owned by it, free and clear of all
liens, encumbrances and defects except such as do not materially affect the
value of such property and do not materially interfere with the use made and
proposed to be made of such property by the Company; and to the Company's
knowledge any real property, mineral or water rights, and buildings held under
lease by the Company as tenant are held by it under valid, subsisting and
enforceable leases with such exceptions as are not material and do not interfere
with the use made and intended to be made of such property, mineral or water
rights, and buildings by the Company.

     Section 4.18.  Intellectual Property.  Each of the Company and its
subsidiaries owns or possesses adequate and enforceable rights to use all
patents, patent applications, trademarks, trademark applications, trade names,
service marks, copyrights, copyright applications, licenses, know-how (including
trade secrets and other unpatented and/or unpatentable proprietary or
confidential information, systems or procedures) and other similar rights and
proprietary knowledge (collectively, "Intangibles") necessary for the conduct of
its business as now being conducted. To the Company's knowledge, except as
disclosed in the SEC Documents neither the Company nor any of its subsidiaries
is infringing upon or in conflict with any right of any other person with
respect to any Intangibles. Except as disclosed in the SEC Documents, no adverse
claims have been asserted by any person to the ownership or use of any
Intangibles and the Company has no knowledge of any basis for such claim.

     Section 4.19.  Internal Controls and Procedures.  The Company maintains
books and records and internal accounting controls which provide reasonable
assurance that (i) all transactions to which the Company or any subsidiary is a
party or by which its properties are bound are executed with management's
authorization; (ii) the recorded accounting of the Company's consolidated assets
is compared with existing assets at regular intervals; (iii) access to the
Company's consolidated assets is permitted only in accordance with management's
authorization; and (iv) all transactions to which the Company or any subsidiary
is a party or by which its properties are bound are recorded as necessary to
permit preparation of the financial statements of the Company in accordance with
U.S. generally accepted accounting principles.

     Section 4.20.  Payments and Contributions.  Neither the Company, any
subsidiary, nor any of its directors, officers or, to its knowledge, other

1977, as amended; or (iv) made any bribe, rebate, payoff, influence payment,
kickback or other similar payment to any person with respect to Company matters.

     Section 4.21.  No Misrepresentation.  The representations and warranties of
the Company contained in this Agreement, any schedule, annex or exhibit hereto
and any agreement, instrument or certificate furnished by the Company to the
Investors pursuant to this Agreement, do not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.

                                   ARTICLE V

                           COVENANTS OF THE INVESTORS

     Each Investor, severally and not jointly, covenants with the Company that:

     Section 5.1.  Compliance with Law.  The Investor's trading activities with
respect to shares of the Company's Common Stock will be in compliance with all
applicable state and federal securities laws, rules and regulations and rules
and regulations of the Principal Market on which the Company's Common Stock is
listed.

                                   ARTICLE VI

                            COVENANTS OF THE COMPANY

     Section 6.1.  Registration Rights.  The Company shall cause the
Registration Rights Agreement to remain in full force and effect and the Company
shall comply in all material respects with the terms thereof.

     Section 6.2.  Reservation of Common Stock.  As of the date hereof, the
Company has reserved and the Company shall continue to reserve and keep
available at all times, free of preemptive rights, shares of Common Stock for
the purpose of enabling the Company to issue the Conversion Shares and the
Warrant Shares pursuant to any conversion of the Convertible Debentures or
exercise of the Warrants. The number of shares so reserved from time to time, as
theretofore increased or reduced as hereinafter provided, may be reduced by the
number of shares actually delivered pursuant to any conversion of the
Convertible Debentures or exercise of the Warrants and the number of shares so
reserved shall be increased or decreased to reflect potential increases or
decreases in the Common Stock that the Company may thereafter be obligated to
issue by reason of adjustments to the Warrants. The Company further agrees that
if at any time 200% of the number of shares of Common Stock issuable upon
conversion of the Convertible Debentures and exercise of the Warrants would
cause the Company to be obligated to issue a number of shares of Common Stock in
excess of its authorized capital (after taking into account all other Capital
Shares Equivalents then existing), it shall promptly commence all necessary
corporate and shareholder action necessary to increase its authorized capital so
as to eliminate the aforesaid condition.

     Section 6.3.  Listing of Common Stock.  The Company hereby agrees to
maintain the listing of the Common Stock on a Principal Market, and as soon as
reasonably practicable following the Closing to list the Conversion Shares and
the Warrant Shares on the Principal Market. The Company further agrees, if the
Company applies to have the Common Stock traded on any other Principal Market,
it will include in such application the Conversion Shares and the Warrant
Shares, and will take such other action as is necessary or desirable in the
opinion of the Investors to cause the Conversion Shares and Warrant Shares to be
listed on such other Principal Market as promptly as possible. The Company will
take all action to continue the listing and trading of its Common Stock on a
Principal Market (including, without limitation, maintaining sufficient net
tangible assets) and will comply in all respects with the Company's reporting,
filing and other obligations under the bylaws or rules of the Principal Market
and shall provide Investors with copies of any correspondence to or from such
Principal Market which questions or threatens delisting of the Common Stock,
within three (3) Trading Days of the Company's receipt thereof, until the
Investors have disposed of all of their Registrable Securities. The Company
agrees to present a proposal for stockholder approval at its next meeting of
stockholders, which shall be scheduled to be held no later than seventy-five
(75) days after the Closing,
                                      C-11
<PAGE>   61

subject only to SEC review of the proxy statement with respect thereto, to
permit the Company to issue a number of Conversion Shares and Warrant Shares
which is in excess of 19.9% of the number of the Company's issued and
outstanding shares of Common Stock on the Closing Date, with the recommendation
of the Board of Directors that such proposal be approved.

     Section 6.4.  Exchange Act Registration.  The Company will cause its Common
Stock to continue to be registered under Section 12(b) or (g) of the Exchange
Act, will use its best efforts to comply in all respects with its reporting and
filing obligations under the Exchange Act, and will not take any action or file
any document (whether or not permitted by the Exchange Act or the rules
thereunder) to terminate or suspend such registration or to terminate or suspend
its reporting and filing obligations under said Act until the Investors have
disposed of all of their Registrable Securities.

     Section 6.5.  Legends.  The certificates evidencing the Registrable
Securities shall be free of legends, except as set forth in Article IX.

     Section 6.6.  Corporate Existence; Conflicting Agreements.  The Company
will take all steps necessary to preserve and continue the corporate existence
of the Company. The Company shall not enter into any agreement, the terms of
which agreement would restrict or impair the right or ability of the Company to
perform any of its obligations under this Agreement or any of the other
agreements attached as exhibits hereto.

     Section 6.7.  Consolidation; Merger.  The Company shall not, at any time
after the date hereof, effect any merger or consolidation of the Company with or
into, or a transfer of all or substantially all of the assets of the Company to,
another entity (a "Consolidation Event") unless the resulting successor or
acquiring entity (if not the Company) assumes by written instrument or by
operation of law the Company's obligations under this Agreement, including the
obligation to deliver to the Investors such shares of stock and/or securities as
the Investors are entitled to receive pursuant to this Agreement and the
Convertible Debentures.

     Section 6.8.  Issuance of Convertible Debentures and Warrant Shares.  The
sale of the Convertible Debentures and the Warrants and the issuance of the
Warrant Shares pursuant to exercise of the Warrants and the Conversion Shares
upon conversion of the Convertible Debentures shall be made in accordance with
the provisions and requirements of Section 4(2), 4(6) or Regulation D and any
applicable state securities law. The Company shall make any necessary SEC and
"blue sky" filings required to be made by the Company in connection with the
sale of the Securities to the Investors as required by all applicable laws, and
shall provide a copy thereof to the Investors promptly after such filing.

     Section 6.9.  Right to Participate in Future Financing.  The Company agrees
that it will not enter into any sale of Capital Shares Equivalents until one
year after the Effective Date of the Registration Statement without offering
each Investor, severally and not jointly, the right to participate in such sale
to the extent of the Investor's pro-rata interest in the Company at such time,
assuming conversion of the Convertible Debenture at that time. This right shall
not apply to the current Hambrecht & Quist equity line or the contemplated
Vector or Boles financing transactions.

     Section 6.10.  Use of Proceeds.  The Company agrees to use the entire net
proceeds from the sale of the Convertible Debentures to repay existing secured
indebtedness of the Company.

                                  ARTICLE VII
                           SURVIVAL; INDEMNIFICATION

     Section 7.1.  Survival.  The representations, warranties and covenants made
by each of the Company and each Investor in this Agreement, the annexes,
schedules and exhibits hereto and in each instrument, agreement and certificate
entered into and delivered by them pursuant to this Agreement, shall survive the
Closing and the consummation of the transactions contemplated hereby. In the
event of a breach or violation of any of such representations, warranties or
covenants, the party to whom such representations, warranties or covenants have
been made shall have all rights and remedies for such breach or violation
available to it under

                                      C-12
<PAGE>   62

the provisions of this Agreement, irrespective of any investigation made by or
on behalf of such party on or prior to the Closing Date.

     Section 7.2.  Indemnity.  (a) The Company hereby agrees to indemnify and
hold harmless the Investors, their respective Affiliates (as defined in SEC Rule
405) and their respective officers, directors, partners and members
(collectively, the "Investor Indemnitees"), from and against any and all
Damages, in each case promptly as incurred by the Investor Indemnitees and to
the extent arising out of or in connection with:

          (i) any misrepresentation, omission of fact or breach of any of the
     Company's representations or warranties contained in this Agreement, the
     annexes, schedules or exhibits hereto or any instrument, agreement or
     certificate entered into or delivered by the Company pursuant to this
     Agreement; or

          (ii) any failure by the Company to perform in any material respect any
     of its covenants, agreements, undertakings or obligations set forth in this
     Agreement, the annexes, schedules or exhibits hereto or any instrument,
     agreement or certificate entered into or delivered by the Company pursuant
     to this Agreement; or

          (iii) any action instituted against the Investors, or any of them, by
     any stockholder of the Company who is not an Affiliate of an Investor, with
     respect to any of the transactions contemplated by this Agreement.

     (b) Each Investor, severally and not jointly, hereby agrees to indemnify
and hold harmless the Company, its Affiliates and their respective officers,
directors, partners and members (collectively, the "Company Indemnitees"), from
and against any and all Damages, in each case promptly as incurred by the
Company Indemnitees and to the extent arising out of or in connection with:

          (i) any misrepresentation, omission of fact, or breach of any of the
     Investor's representations or warranties contained in this Agreement, the
     annexes, schedules or exhibits hereto or any instrument, agreement or
     certificate entered into or delivered by the Investor pursuant to this
     Agreement; or

          (ii) any failure by the Investor to perform in any material respect
     any of its covenants, agreements, undertakings or obligations set forth in
     this Agreement or any instrument, certificate or agreement entered into or
     delivered by the Investor pursuant to this Agreement.

     Section 7.3.  Notice.  Promptly after receipt by either party hereto
seeking indemnification pursuant to Section 7.2 (an "Indemnified Party") of
written notice of any investigation, claim, proceeding or other action in
respect of which indemnification is being sought (each, a "Claim"), the
Indemnified Party promptly shall notify the party from whom indemnification
pursuant to Section 7.2 is being sought (the "Indemnifying Party") of the
commencement thereof; but the omission to so notify the Indemnifying Party shall
not relieve it from any liability that it otherwise may have to the Indemnified
Party, except to the extent that the Indemnifying Party is actually prejudiced
by such omission or delay. In connection with any Claim as to which both the
Indemnifying Party and the Indemnified Party are parties, the Indemnifying Party
shall be entitled to assume the defense thereof. Notwithstanding the assumption
of the defense of any Claim by the Indemnifying Party, the Indemnified Party
shall have the right to employ separate legal counsel and to participate in the
defense of such Claim, and the Indemnifying Party shall bear the reasonable
fees, out-of-pocket costs and expenses of such separate legal counsel to the
Indemnified Party if (and only if): (x) the Indemnifying Party shall have agreed
to pay such fees, out-of-pocket costs and expenses, (y) the Indemnified Party
reasonably shall have concluded that representation of the Indemnified Party and
the Indemnifying Party by the same legal counsel would not be appropriate due to
actual or, as reasonably determined by legal counsel to the Indemnified Party,
potentially differing interests between such parties in the conduct of the
defense of such Claim, or if there may be legal defenses available to the
Indemnified Party that are in addition to or disparate from those available to
the Indemnifying Party, or (z) the Indemnifying Party shall have failed to
employ legal counsel reasonably satisfactory to the Indemnified Party within a
reasonable period of time after notice of the commencement of such Claim. If the
Indemnified Party employs separate legal counsel in circumstances other than as
described in clauses (x), (y) or (z) above, the fees, costs and expenses of such
legal counsel shall be borne exclusively by the Indemnified Party. Except as
provided above, the Indemnifying Party shall
                                      C-13
<PAGE>   63

not, in connection with any Claim in the same jurisdiction, be liable for the
fees and expenses of more than one firm of legal counsel for the Indemnified
Party (together with appropriate local counsel). The Indemnifying Party shall
not, without the prior written consent of the Indemnified Party (which consent
shall not unreasonably be withheld), settle or compromise any Claim or consent
to the entry of any judgment that does not include an unconditional release of
the Indemnified Party from all liabilities with respect to such Claim or
judgment.

     Section 7.4.  Direct Claims.  In the event one party hereunder should have
a claim for indemnification that does not involve a claim or demand being
asserted by a third party, the Indemnified Party promptly shall deliver notice
of such claim to the Indemnifying Party. If the Indemnified Party disputes the
claim, such dispute shall be resolved by mutual agreement of the Indemnified
Party and the Indemnifying Party or by binding arbitration conducted in
accordance with the procedures and rules of the American Arbitration Association
as set forth in Article X. Judgment upon any award rendered by any arbitrators
may be entered in any court having competent jurisdiction thereof.

                                  ARTICLE VIII
        DUE DILIGENCE REVIEW; NON-DISCLOSURE OF NON-PUBLIC INFORMATION.

     Section 8.1.  Due Diligence Review.  Subject to Section 8.2, the Company
shall make available for inspection and review by the Investors, advisors to and
representatives of the Investors (who may or may not be affiliated with the
Investors and who are reasonably acceptable to the Company), any underwriter
participating in any disposition of the Registrable Securities on behalf of the
Investors pursuant to the Registration Statement, any such registration
statement or amendment or supplement thereto or any blue sky, Nasdaq or other
filing, all SEC Documents and other filings with the SEC, and all other publicly
available corporate documents and properties of the Company as may be reasonably
necessary for the purpose of such review, and cause the Company's officers,
directors and employees to supply all such publicly available information
reasonably requested by the Investors or any such representative, advisor or
underwriter in connection with such Registration Statement (including, without
limitation, in response to all questions and other inquiries reasonably made or
submitted by any of them), prior to and from time to time after the filing and
effectiveness of the Registration Statement for the sole purpose of enabling the
Investors and such representatives, advisors and underwriters and their
respective accountants and attorneys to conduct initial and ongoing due
diligence with respect to the Company and the accuracy of the Registration
Statement.

     Section 8.2.  Non-Disclosure of Non-Public Information.  (a) The Company
shall not disclose material non-public information to the Investors, advisors to
or representatives of the Investors unless prior to disclosure of such
information the Company identifies such information as being non-public
information and provides the Investors, such advisors and representatives with
the opportunity to accept or refuse to accept such non-public information for
review. Other than disclosure of any comment letters received from the SEC staff
with respect to the Registration Statement, the Company may, as a condition to
disclosing any non-public information hereunder, require the Investors' advisors
and representatives to enter into a confidentiality agreement in form and
content reasonably satisfactory to the Company and the Investors.

     (b) Nothing herein shall require the Company to disclose material
non-public information to the Investors or their advisors or representatives,
and the Company represents that it does not disseminate material non-public
information to any investors who purchase stock in the Company in a public
offering, to money managers or to securities analysts, provided, however, that
notwithstanding anything herein to the contrary, the Company will, as
hereinabove provided, promptly notify the advisors and representatives of the
Investors and, if any, underwriters, of any event or the existence of any
circumstance (without any obligation to disclose the specific event or
circumstance) of which it becomes aware, constituting material non-public
information (whether or not requested of the Company specifically or generally
during the course of due diligence by such persons or entities), which, if not
disclosed in the prospectus included in the Registration Statement would cause
such prospectus to include a material misstatement or to omit a material fact
required to be stated therein in order to make the statements, therein in light
of the circumstances in which they were made, not misleading. Nothing contained
in this Section 8.2 shall be construed to mean that such persons or
                                      C-14
<PAGE>   64

entities other than the Investors (without the written consent of the Investors
prior to disclosure of such information as set forth in Section 8.2(a)) may not
obtain non-public information in the course of conducting due diligence in
accordance with the terms of this Agreement and nothing herein shall prevent any
such persons or entities from notifying the Company of their opinion that based
on such due diligence by such persons or entities, that the Registration
Statement contains an untrue statement of a material fact or omits a material
fact required to be stated in the Registration Statement or necessary to make
the statements contained therein, in light of the circumstances in which they
were made, not misleading.

                                   ARTICLE IX
                      LEGENDS; TRANSFER AGENT INSTRUCTIONS

     Section 9.1.  Legends.  Unless otherwise provided below, each certificate
representing Registrable Securities will bear the following legend or equivalent
(the "Legend"):

     THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER
     THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY
     OTHER APPLICABLE SECURITIES LAWS AND HAVE BEEN ISSUED IN RELIANCE UPON AN
     EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND SUCH
     OTHER SECURITIES LAWS. NEITHER THIS SECURITY NOR ANY INTEREST OR
     PARTICIPATION HEREIN MAY BE SOLD, ASSIGNED, TRANSFERRED, PLEDGED,
     ENCUMBERED, OR OTHERWISE DISPOSED OF, EXCEPT PURSUANT TO AN EFFECTIVE
     REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO A
     TRANSACTION THAT IS EXEMPT FROM SUCH REGISTRATION.

     Section 9.2.  Transfer Agent Instructions.  Upon Closing, the Company will
issue to the transfer agent for its Common Stock (and to any substitute or
replacement transfer agent for its Common Stock upon the Company's appointment
of any such substitute or replacement transfer agent) instructions substantially
in the form of Exhibit F hereto. Such instructions shall be irrevocable by the
Company from and after the date hereof or from and after the issuance thereof to
any such substitute or replacement transfer agent, as the case may be.

     Section 9.3.  No Other Legend or Stock Transfer Restrictions.  No legend
other than the one specified in Section 9.1 has been or shall be placed on the

                           CHOICE OF LAW; ARBITRATION

     Section 10.1.  Governing Law/Arbitration.  This Agreement shall be governed
by and construed in accordance with the laws of the State of New York applicable
to contracts made in New York by persons domiciled in New York City and without
regard to its principles of conflicts of laws. Any dispute under this Agreement
shall be submitted to arbitration under the American Arbitration Association
(the "AAA") in New York City, New York, and shall be finally and conclusively
determined by the decision of a board of arbitration consisting of three (3)
members (hereinafter referred to as the "Board of Arbitration") selected
according to the rules governing the AAA. The Board of Arbitration shall meet on
consecutive business days in New York City, New York, and shall reach and render
a decision in writing (concurred in by a majority of the members of the Board of
Arbitration) with respect to the amount, if any, which the losing party is
required to pay to the other party in respect of a claim filed. In connection
with rendering its decisions, the Board of Arbitration shall adopt and follow
the laws of the State of New York unless the matter at issue is the
                                      C-15
<PAGE>   65

corporation law of the company's state of incorporation, in which event the
corporation law of such jurisdiction shall govern such issue. To the extent
practical, decisions of the Board of Arbitration shall be rendered no more than
thirty (30) calendar days following commencement of proceedings with respect
thereto. The Board of Arbitration shall cause its written decision to be
delivered to all parties involved in the dispute. Any decision made by the Board
of Arbitration (either prior to or after the expiration of such thirty (30)
calendar day period) shall be final, binding and conclusive on the parties to
the dispute, and entitled to be enforced to the fullest extent permitted by law
and entered in any court of competent jurisdiction. The Board of Arbitration
shall be authorized and is hereby directed to enter a default judgment against
any party failing to participate in any proceeding hereunder within the time
periods set forth in the AAA rules. The non-prevailing party to any arbitration

        OF ANY STATE OR UNDER THE SECURITIES ACT OF 1933, AS AMENDED

                              UOL PUBLISHING, INC.

      9% SECURED SUBORDINATED CONVERTIBLE DEBENTURE DUE DECEMBER 15, 2000

     THIS DEBENTURE is issued by UOL PUBLISHING, INC., a corporation organized
and existing under the laws of the State of Delaware (the "Company") and is
designated as its 9% Secured Subordinated Convertible Debenture Due December 15,
2000.

     FOR VALUE RECEIVED, the Company promises to pay to [INVESTOR], or permitted
assigns (the "Holder"), the principal sum of [          AND 00/100 (US $XX,000)
DOLLARS] on December 15, 2000 (the "Maturity Date") and to pay interest on the
principal sum outstanding from time to time quarterly in arrears at the rate of
9% per annum accruing from the date of initial issuance. Accrual of interest
shall commence on the first business day to occur after the date of initial
issuance and continue daily on the basis of a 360 day year until payment in full
of the principal sum has been made or duly provided for. Quarterly interest
payments shall be due and payable on September 1, December 1, March 1 and June 1
of each year, commencing with September 1, 1999. If any interest payment date or
the Maturity Date is not a business day in the State of New York, then such
payment shall be made on the next succeeding business day. Subject to the
provisions of Section 4 below, principal and accrued interest on this Debenture
is payable at the option of the Company, in cash or in registered shares of
Common Stock of the Company, $.01 par value per share ("Common Stock") valued at
the Conversion Price (as defined herein) on the interest payment date or the
Maturity Date, as applicable, at the address last appearing on the Debenture
Register of the Company as designated in writing by the Holder from time to
time. The Company will pay the principal of and any accrued but unpaid interest
due upon this Debenture on the Maturity Date, less any amounts required by law
to be deducted, to the registered holder of this Debenture as of the tenth day
prior to the Maturity Date and addressed to such holder at the last address
appearing on the Debenture Register. The forwarding of such check, or the
required number of shares of Common Stock determined pursuant to the provisions
of Section 4 below, shall constitute a payment of principal and interest
hereunder and shall satisfy and discharge the liability for principal and
interest on this Debenture to the extent of the sum represented by such check or
the equivalent Conversion Price value of such shares of Common Stock (as defined
in Section 3 below) plus any amounts so deducted.

     This Debenture is subject to the following additional provisions:

     1. The Company shall be entitled to withhold from all payments of principal
of, and interest on, this Debenture any amounts required to be withheld under
the applicable provisions of the United States income tax laws or other
applicable laws at the time of such payments, and Holder shall execute and
deliver all required documentation in connection therewith.

     2. This Debenture has been issued subject to investment representations of
the original purchaser hereof and may be transferred or exchanged only in
compliance with the Securities Act of 1933, as amended (the

                                       D-1
<PAGE>   70

"Act"), and other applicable state and foreign securities laws. The Holder shall
deliver written notice to the Company of any proposed transfer of this
Debenture. In the event of any proposed transfer of this Debenture, the Company
may require, prior to issuance of a new Debenture in the name of such other
person, that it receive reasonable transfer documentation including legal
opinions that the issuance of the Debenture in such other name does not and will
not cause a violation of the Act or any applicable state or foreign securities
laws. Prior to due presentment for transfer of this Debenture, the Company and
any agent of the Company may treat the person in whose name this Debenture is
duly registered on the Company's Debenture Register as the owner hereof for the
purpose of receiving payment as herein provided and for all other purposes,
whether or not this Debenture be overdue, and neither the Company nor any such
agent shall be affected by notice to the contrary. This Debenture has been
executed and delivered pursuant to the Convertible Debenture and Warrants
Purchase Agreement dated as of June 4, 1999 between the Company and the original
Holder (the "Purchase Agreement"), and is subject to the terms and conditions of
the Purchase Agreement, which are, by this reference, incorporated herein and
made a part hereof. Capitalized terms used and not otherwise defined herein
shall have the meanings set forth for such terms in the Purchase Agreement.

     3. Subject to Section 4 below, the Holder of this Debenture is entitled, at
its option, to convert at any time commencing ninety (90) days after the date
hereof, the principal amount of this Debenture or any portion thereof, together
with accrued but unpaid interest, into shares of Common Stock of the Company
("Conversion Shares"); provided, that the Holder may not convert more than
fifteen percent (15%) of the original principal balance of this Debenture per
month, on a cumulative basis. For further clarity, if the Holder does not
convert any part of this Debenture in month one, it may convert up to 30% of the
original principal balance at the beginning of month 2, and would be able to
convert a further 15% of the original principal balance at the beginning of
month three. The conversion price for each share of Common Stock ("Conversion
Price") shall be $5.55 and shall be adjusted proportionately for any subsequent
stock splits, stock dividends and reverse stock splits.

     4. If the Market Price (as defined in the Purchase Agreement) on any
Conversion Date is less than the Conversion Price established in Section 3, then
the Company shall have the option, upon at least seven (7) days' prior written
notice to the holder, to pay the Holder (i) in shares of Common Stock with a
Conversion Price equal to eighty-five percent (85%) of the two lowest
consecutive closing bid prices of the Common Stock during the twenty (20)
Trading Days immediately preceding the Conversion Date, or else (ii) in cash in
an amount equal to 110% of the principal amount sought to be converted, if such
Conversion Date occurs no later than 210 days after the date hereof, or 115% of
the principal amount sought to be converted at any time thereafter, together
with, in either case, all accrued but unpaid interest thereon. Further, if the
Company shall honor any conversion request in cash in accordance with this
Section no later than 210 days after the date hereof, the Company shall also
issue the Holder an additional number of Warrants, identical to the Warrants
issued at Closing, in a number equal to twenty percent (20%) of the number of
Warrants issued to the holder at Closing. If notice of the Company's election to
pay the holder in cash is not received by the Holder at least seven (7) days
prior to the receipt by the Company of a Conversion Notice, the Company shall
pay the holder in shares of Common Stock. Notwithstanding anything to the
contrary contained herein, in the event that a conversion (when aggregated with
all prior conversions of portions of this Debenture and any other Convertible
Debenture issued pursuant to the Purchase Agreement and all shares of Common
Stock issuable upon exercise of the Warrants (as defined in the Purchase
Agreement)) required the Company to issue a number of shares of Common Stock
which would exceed 19.9% of the number of shares of Common Stock issued and
outstanding on the issuance date of this Debenture, the Company shall issue only
such number of shares of Common Stock as shall not exceed such limit and shall
pay the Holder cash in the amount of the Market Price for the number of shares
of Common Stock in excess of such number of shares into which this Debenture (or
the portion thereof then being converted) is then convertible at the current
Conversion Price, unless the Company has obtained shareholder approval for such
issuance pursuant to the rules of The Nasdaq Stock Market, or as otherwise
permitted by The Nasdaq Stock Market.

     5. (a) Conversion shall be effectuated by surrendering this Debenture to
the Company (if such Conversion will convert all outstanding principal) together
with the form of conversion notice attached hereto as Exhibit A (the "Notice of
Conversion"), executed by the Holder of this Debenture evidencing such

                                       D-2
<PAGE>   71

Holder's intention to convert this Debenture or a specified portion (as above
provided) hereof, and accompanied, if required by the Company, by proper
assignment hereof in blank. Interest accrued or accruing from the date of
issuance to the date of conversion shall, at the option of the Company, be paid
in cash as set forth above or in Common Stock upon conversion at the Conversion
Price on the Conversion Date. No fraction of a share or scrip representing a
fraction of a share will be issued on conversion, but the number of shares
issuable shall be rounded to the nearest whole share, without compensation to
the holder or the Company for such fraction. The date on which Notice of
Conversion is given (the "Conversion Date") shall be deemed to be the date on
which the Holder faxes the Notice of Conversion duly executed to the Company.
Facsimile delivery of the Notice of Conversion shall be accepted by the Company
at facsimile number (703) 893-1905 Attn.: Narasimhan P. Kannan, C.E.O.
Certificates representing Common Stock upon conversion will be delivered to the
Holder within three (3) Trading Days from the date the Notice of Conversion is
delivered to the Company. Delivery of shares upon conversion shall be made to
the address specified by the Holder in the Notice of Conversion.

       (b) The Company understands that a delay in the issuance of shares of
Common Stock upon a conversion beyond the five (5) Trading Day period described
in Section 5(a) could result in economic loss to the Holder. As compensation to
the Holder for such loss, the Company agrees to pay liquidated damages to the
Holder for late issuance of shares of Common Stock upon conversion in the amount
of three percent (3%) per month of the principal amount converted, pro-rated for
each day of delay beyond five (5) Trading Days; provided, that such liquidated
damages shall be tolled for each Trading Day when such delivery is delayed due
to force majeure.

     The Company shall pay any payments incurred under this Section 5(b) in
immediately available funds upon demand. Nothing herein shall limit Holder's
right to pursue injunctive relief and/or actual damages for the Company's
failure to issue and deliver Common Stock to the Holder, including, without
limitation, the Holder's actual losses occasioned by any "buy-in" of Common
Stock necessitated by such late delivery. Furthermore, in addition to any other
remedies which may be available to the Holder, in the event that the Company
fails for any reason to effect delivery of such shares of Common Stock within
five (5) Trading Days from the date the Notice of Conversion is delivered to the
Company, the Holder will be entitled to revoke the relevant Notice of Conversion
by delivering a notice to such effect to the Company, whereupon the Company and
the Holder shall each be restored to their respective positions immediately
prior to delivery of such Notice of Conversion, and in such event no liquidated
damages shall be due in connection with such withdrawn conversion.

       (c) The Holder shall be entitled to exercise its conversion privilege
notwithstanding the commencement of any case under 11 U.S.C. sec. 101 et seq.
(the "Bankruptcy Code"). In the event the Company is a debtor under the
Bankruptcy Code, the Company hereby waives to the fullest extent permitted any
rights to relief it may have under 11 U.S.C. sec. 362 in respect of the Holder's
conversion privilege.

     6. No provision of this Debenture shall alter or impair the obligation of
the Company, which is absolute and unconditional, to pay the principal of, and
interest on, this Debenture at the time, place, and rate, and in the coin or
currency or shares of Common Stock, herein prescribed. This Debenture is a
direct obligation of the Company.

     7. No recourse shall be had for the payment of the principal of, or the
interest on, this Debenture, or for any claim based hereon, or otherwise in
respect hereof, against any incorporator, shareholder, employee, officer or
director, as such, past, present or future, of the Company or any successor
corporation, whether by virtue of any constitution, statute or rule of law, or
by the enforcement of any assessment or penalty or otherwise, all such liability
being, by the acceptance hereof and as part of the consideration for the issue
hereof, expressly waived and released.

     8. If any of the following events occurs:

          (a) the Company merges or consolidates with another corporation or
     sells or transfers all or substantially all of its assets to another
     person; or

                                       D-3
<PAGE>   72

          (b) the Company fails to issue shares of Common Stock to the Holder or
     to cause its Transfer Agent to issue shares of Common Stock upon exercise
     by the Holder of the conversion rights of the Holder in accordance with the
     terms of this Debenture, fails to transfer or to cause its Transfer Agent
     to transfer any certificate for shares of Common Stock issued to the Holder
     upon conversion of this Debenture as and when required by this Debenture or
     the Registration Rights Agreement, and such transfer is otherwise lawful,
     or fails to remove any restrictive legend or to cause its Transfer Agent to
     transfer any certificate or any shares of Common Stock issued to the Holder
     upon conversion of this Debenture as and when required by this Debenture,
     the Purchase Agreement or the Registration Rights Agreement and such legend
     removal is otherwise lawful, and any such failure shall continue uncured
     for five (5) business days; or

          (c) the Company shall fail to perform or observe, in any material
     respect, any other covenant, term, provision, condition, agreement or
     obligation of the Company under the Purchase Agreement, the Security
     Agreement, the Registration Rights Agreement or this Debenture, including,
     without limitation, any failure to obtain shareholder approval to issue
     shares upon conversion of this Debenture in excess of 19.9% of the number
     of shares of Common Stock issued and outstanding on the issuance date
     hereof, or to cause an increase in the authorized capital of the Company
     when required by the Purchase Agreement, or the Company does not have
     registered shares of Common Stock available for issuance upon conversion of
     this Debenture at any time after the period required by the Registration
     Rights Agreement, or the Registration Statement is not effective within 150
     days of the issuance date hereof, or the Registration Statement shall be
     suspended from effectiveness for any reason for in excess of thirty (30)
     days in any twelve (12) month period, and such failure shall continue
     uncured for a period of five (5) days after written notice from the Holder
     of such failure; or

          (d) the Company shall not have its Common Stock listed for trading on
     a Principal Market for in excess of five (5) Trading Days;

     Then, in any of such events, the Company shall, upon written demand of the
     Holder, repurchase this Debenture at a price equal to the fair market value
     of the shares of Common Stock the remaining principal balance hereof, plus
     all accrued but unpaid interest through the date of such repayment, would
     otherwise convert into. Such payment shall be made within three (3) Trading
     Days of such demand, and if not paid within such period, the Company shall
     pay the Holder liquidated damages of three percent (3%) per month of such
     amount until paid, pro-rated for any partial months.

     9. The Holder of the Debenture, by acceptance hereof, agrees that this
Debenture is being acquired for investment and that such Holder will not offer,
sell or otherwise dispose of this Debenture or the Shares of Common Stock
issuable upon conversion thereof except under circumstances which will not
result in a violation of the Act or any applicable state Blue Sky or foreign
laws or similar laws relating to the sale of securities.

     10. This Debenture shall be governed by and construed in accordance with
the laws of the State of New York. Each of the parties consents to the
jurisdiction of the federal courts whose districts encompass any part of the
City of New York or the state courts of the State of New York sitting in the
City of New York in connection with any dispute arising under this Agreement and
hereby waives, to the maximum extent permitted by law, any objection, including
any objection based on forum non conveniens, to the bringing of any such
proceeding in such jurisdictions.

     11. The following shall constitute an "Event of Default":

        a. The Company shall default in the payment of principal or interest on
           this Debenture and same shall continue for a period of five (5)
           Trading Days; or

        b. Any of the representations or warranties made by the Company herein,
           in the Purchase Agreement, the Registration Rights Agreement, or in
           any agreement, certificate or financial or other written statements
           heretofore or hereafter furnished by the Company in connection with
           the execution and delivery of this Debenture or the Purchase
           Agreement shall be false or misleading in any material respect at the
           time made; or
                                       D-4
<PAGE>   73

        c. Any Senior Debt (as defined herein) shall declare an Event of Default
           with respect to such Senior Debt; or

        d. The Company shall (1) admit in writing its inability to pay its debts
           generally as they mature; (2) make an assignment for the benefit of
           creditors or commence proceedings for its dissolution; or (3) apply
           for or consent to the appointment of a trustee, liquidator or
           receiver for its or for a substantial part of its property or
           business; or

        e. A trustee, liquidator or receiver shall be appointed for the Company
           or for a substantial part of its property or business without its
           consent and shall not be discharged within sixty (60) days after such
           appointment; or

        f. Any governmental agency or any court of competent jurisdiction at the
           instance of any governmental agency shall assume custody or control
           of the whole or any substantial portion of the properties or assets
           of the Company and shall not be dismissed within sixty (60) days
           thereafter; or

        g. Any money judgment, writ or warrant of attachment, or similar process
           in excess of One Hundred Thousand ($100,000) Dollars in the aggregate
           shall be entered or filed against the Company or any of its
           properties or other assets and shall remain unpaid, unvacated,
           unbonded or unstayed for a period of sixty (60) days or in any event
           later than five (5) days prior to the date of any proposed sale
           thereunder; or

        h. Bankruptcy, reorganization, insolvency or liquidation proceedings or
           other proceedings for relief under any bankruptcy law or any law for
           the relief of debtors shall be instituted by or against the Company
           and, if instituted against the Company, shall not be dismissed within
           sixty (60) days after such institution or the Company shall by any
           action or answer approve of, consent to, or acquiesce in any such
           proceedings or admit the material allegations of, or default in
           answering a petition filed in any such proceeding; or

        i. The Company challenges, disputes or denies the right of the Holder to
           effect the conversion of this Debenture into Common Stock or
           otherwise dishonors or rejects any Notice of Conversion delivered in
           accordance with Section 5 or any Company stockholder who is not and
           has never been an Affiliate (as defined in Rule 405 under the
           Securities Act of 1933, as amended) of the Holder obtains a judgment
           or any injunctive relief from any court or public or governmental
           authority which denies, enjoins, limits, modifies, delays or disputes
           the right of the holder hereof to effect the conversion of this
           Debenture into Common Stock.

Then, or at any time thereafter, and in each and every such case, unless such
Event of Default shall have been waived in writing by a majority in interest of
the holders of this series of Debentures (which waiver shall not be deemed to be
a waiver of any subsequent default) and subject to the prior rights of the
Senior Debt as defined in Section 14 hereof, at the option of a majority in
interest of the holders and in the holders' sole discretion, the Holder may
consider this Debenture immediately due and payable, without presentment,
demand, protest or notice of any kind, all of which are hereby expressly waived,
anything herein or in any note or other instruments contained to the contrary
notwithstanding, and the Holder may immediately enforce any and all of the
Holder's rights and remedies provided herein or any other rights or remedies
afforded by law; provided, that any payment of this Debenture in connection with
an Event of Default shall be made at the fair market value of the shares of
Common Stock which would be issued at the Conversion Price on the date the
Debenture becomes due and payable pursuant to this provision. Such payment shall
be made within three (3) Trading Days of such demand, and if not paid within
such period, the Company shall pay the holder liquidated damages of three
percent (3%) per month of such amount until paid, pro-rated for any partial
months.

     12. Nothing contained in this Debenture shall be construed as conferring
upon the Holder the right to vote or to receive dividends or to consent or
receive notice as a shareholder in respect of any meeting of shareholders or any
rights whatsoever as a shareholder of the Company, unless and to the extent
converted in accordance with the terms hereof.
                                       D-5
<PAGE>   74

     13. In no event shall the Holder be permitted to convert this Debenture for
shares of Common Stock in excess of the amount of this Debenture upon the
conversion of which, (x) the number of shares of Common Stock owned by such
Holder (other than shares of Common Stock issuable upon conversion of this
Debenture) plus (y) the number of shares of Common Stock issuable upon
conversion of this Debenture, would be equal to or exceed 9.9% of the number of
shares of Common Stock then issued and outstanding, including shares issuable
upon conversion of this Debenture held by such Holder after application of this
Section 13. As used herein, beneficial ownership shall be determined in
accordance with Section 13(d) of the Securities Exchange Act of 1934, as
amended, and the rules and regulations thereunder. To the extent that the
limitation contained in this Section 13 applies, the determination of whether
this Debenture is convertible (in relation to other securities owned by the
Holder) and of which a portion of this Debenture is convertible shall be in the
sole discretion of such Holder, and the submission of a Notice of Conversion
shall be deemed to be such Holder's determination of whether this Debenture is
convertible (in relation to other securities owned by such holder) and of which
portion of this Debenture is convertible, in each case subject to such aggregate
percentage limitation, and the Company shall have no obligation to verify or
confirm the accuracy of such determination. Nothing contained herein shall be
deemed to restrict the right of a holder to convert this Debenture into shares
of Common Stock at such time as such conversion will not violate the provisions
of this Section 13. The provisions of this Section 13 may be waived by the
Holder of this Debenture upon not less than 75 days' prior notice to the
Company, and the provisions of this Section 13 shall continue to apply until
such 75th day (or such later date as may be specified in such notice of waiver).
No conversion of this Debenture in violation of this Section 13 but otherwise in
accordance with this Debenture shall affect the status of the Common Stock
issued upon such conversion as validly issued, fully-paid and nonassessable. If
on the Maturity Date the conversion of this Debenture into Common Stock pursuant
to Section 4 would cause the limit contained in the first sentence of this
Section 13 to be exceeded, such conversion of this Debenture shall occur up to
such limit and the remaining unconverted portion of this Debenture shall be
converted into Common Stock (1) in accordance with one or more Notices of
Conversion delivered by the Holder or (2) 65 days after the Maturity Date,
whichever is earlier. Notwithstanding anything contained herein to the contrary,
no interest shall accrue after the Maturity Date on any such unconverted portion
of this Debenture.

     14. In the event of any distribution, division or application, partial or
complete, voluntary or involuntary, by operation of law or otherwise, of all or
any part of the assets of the Company, or the proceeds thereof, to creditors of
the company or upon any indebtedness of the Company, by reason of the
liquidation, dissolution or other winding-up of the Company, or the Company's
business or affairs, or in the event of any sale, receivership, insolvency or
bankruptcy proceeding, assignment for the benefit of creditors or any other
proceeding by or against the Company for any relief under any bankruptcy or
insolvency law or laws relating to the relief of debtors, readjustment of
indebtedness, reorganizations, compositions or extensions, then, and in each
such event, each payment or distribution of any kind or character, either in
cash, securities or other property, which shall be payable or deliverable upon
or with respect to any of the obligations of the Company evidenced by this Note
shall, until $1,000,000 in the aggregate of such payments and distributions
shall have been paid on account of the Senior Debt (as defined below), be paid
directly to the holders of the Senior Debt, for application on account of the
Senior Debt. So long as any such Senior debt is outstanding or there exists any
commitment which could give rise to any Senior Debt, upon the occurrence of an
Event of Default hereunder, Holder shall not, for a period of up to 30 days from
the occurrence of each such Event of Default, accelerate or declare that this
Note is forthwith due and payable, nor during such 30 day period shall Holder
sue for payment of the Note or commence or join with any other creditor of the
Company other than the holders of the Senior Debt or their agents until and
unless the holders of the Senior Debt have accelerated the Senior Debt or the
Company shall have initiated a bankruptcy proceeding, provided, that nothing
contained herein shall prohibit or prevent the Holder from delivering written
notice of default to the Company or to the holders of any of the Senior Debt.
"Senior Debt" shall mean all existing and future obligations of the Company to
one or more lenders in connection with loans in the maximum principal amount of
$1,000,000 extended or to be extended by such lenders to the Company, and shall
include the outstanding principal amount of such Senior Debt from time to time,
whenever incurred.

     15. The obligations of the Company pursuant to this instrument are secured
by a security interest in substantially all of the Company's assets, as set
forth in a Security Agreement of even date herewith.

     IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed by an officer thereunto duly authorized.
