Subject to the provisions of Section XVII herein, the maximum number of shares
of Stock that may be optioned or sold under the Plan is 650,000 shares.  Such

IV.              ADMINISTRATION

The Committee shall administer the Plan.  Two members of the Committee shall
constitute a quorum for the transaction of business.  The Committee shall be
responsible to the Board for the operation of the Plan, and shall make
recommendations to the Board with respect to participation in the Plan by
Employees and with respect to the extent of that participation. The
interpretation and construction of any provision of the Plan by the Committee
shall be final, unless otherwise determined by the Board. No member of the
Board or the Committee shall be liable for any action or determination made by
him in good faith.

The Board, upon recommendation of the Committee, may grant Options to any
Employee upon such terms and conditions as it determines appropriate, including
but not limited to provisions regarding vesting of Options granted, and
covenants not to compete and confidentiality requirements.  Options may be
awarded by the Board at any time and from time to time to new Participants, or
to a greater or lesser number of Participants, and may include or exclude
previous Participants, as the Board, upon recommendation by the Committee,
shall determine.  Options granted at different times need not contain similar
provisions and no grant of Options shall be effective until such time as the
Employee enters into the Option Agreement presented by the Board in conjunction
with such grant of Options, by executing and returning such agreement to the
Board.

V.               OPTION PRICE

The purchase price for Stock under each Option shall not be less than the fair
market value of the Stock at the close of business on the date the Option is
granted, but in no event less than the par value of the Stock.  For purposes of

lowest price for a share of Stock, as quoted on the American Stock Exchange (or

preceding the date of the grant.

VI.              EXERCISE OF STOCK OPTIONS

A Stock Option shall be exercised by a Participant or other person authorized
under this Plan to exercise such Option by the provision of written notice, on
a form approved by the Committee, indicating the person's intention to exercise
same, accompanied by full payment of the purchase price.  Said purchase price
shall be paid with cash or certified check, or with a surrender of Stock having
a fair market value on the date of exercise equal to that portion of the
purchase price for which payment in cash or by certified check is not made.  In
the event that Stock is surrendered upon exercise of an Option, certificates
evidencing the shares to be so used shall be delivered to the Company and shall
be duly endorsed or accompanied by duly executed stock powers to transfer the
same to the Company; provided, however, that such payment in Stock instead of
cash or cashier's check shall not be effective and shall be rejected by the
Company if (a) the

                                      -2-
<PAGE>   3
Company is then prohibited from purchasing shares of the class of the stock
thus tendered to it, or (b) the right or power of the person exercising the
Option to deliver such shares in payment of the purchase price is subject to
restrictions (determined as of the date such Stock is tendered), including but
not limited to the prior interest of any other person as indicated by legends
upon the certificate(s) or known to the Company.  If the Company rejects the
payment in stock, the tendered notice of exercise shall not be effective
hereunder unless, after being notified of such rejection, the person exercising
the Option pays the purchase price in an acceptable form.  The Company shall be
entitled, at its option, to return those shares of Stock as part of the shares
for which the Option was exercised rather than re-issuing new shares.

The Company shall have the right to require a Participant, or any other person
authorized to exercise Options under this Plan, to pay to the Company the
amount of any taxes which the Company is required to withhold as a result of
the exercise of said Option.

VII.             TERMS AND CONDITIONS OF OPTIONS

Options granted pursuant to the Plan shall be authorized by the Board and shall
be evidenced by agreements in such form as the Board, upon recommendation of
the Committee, shall from time to time approve.  Such Agreements shall include
a provision that during the period in which a Participant is employed by the
Company, Participant shall be limited in trading shares of the Company acquired
through exercise of any Option in accordance with the Company's then current
policy governing trading in the shares of the Company by Officers and
Directors.

VIII.            EMPLOYMENT AGREEMENT

The Board may, in its discretion, include in any Option granted under the Plan
a condition that the Participant shall agree to remain in the employ of, and to
render services to, the Company or any of its Subsidiaries for a period of time
(specified in the agreement) following the date the Option is granted. However,
no such agreement shall impose any obligation upon the Company to employ the
Participant for any period of time.

IX.              TIME AND METHOD OF PAYMENT

The Option Price shall be paid in full either in cash or under a cash-less
option provision (depending on the form of Option Agreement granted to the
Participant) at the time an Option is exercised under the Plan. Otherwise, an
exercise of any Option granted under the Plan shall be invalid and of no
effect. Promptly after the exercise of an Option and the payment of the full
Option Price, the Participant shall be entitled to the issuance of a stock
certificate evidencing his ownership of such Stock.  Participant shall have
none of the rights of a shareholder until shares are issued to him, and no
adjustment will be made for dividends or other rights for which the record date
is prior to the date such stock certificate is issued.

X.               NUMBER OF SHARES

Each Option shall state the total number of shares of Stock to which it
pertains and the number of Shares to which a participant is entitled under an
Option agreement.

XI.              OPTION PERIOD, AND LIMITATIONS ON EXERCISE OF OPTIONS

The Board may, in its discretion, provide that an Option may not be exercised
in whole or in part for any period or periods of time specified in the Option
agreement. Except as provided in the Option agreement or otherwise herein, an
Option maybe exercised in whole or in part at any time during its term. No
Option may be exercised after the expiration of ten (10) years from the date it
is granted. No Option may be exercised for a fractional share of Stock.

XII.             TERMINATION OF EMPLOYMENT

Except as provided in Section XIII below, if a Participant ceases to be
employed by the Company, his Options shall terminate immediately; provided,
however, that the Participant may, at any time within three months after such
cessation of employment, exercise his Options to the extent that he was
entitled to exercise them on the date of cessation of employment, but in no
event shall any option be exercisable more than ten (10) years from the date it
was granted.

Notwithstanding the forgoing, in the event of a sale, spinoff, merger,
consolidation or other transaction by which Medical Advisory Systems, Inc.
disposes of its interest in a Subsidiary, the Options of Participants employed
by such Subsidiary not previously exercisable and vested shall become fully
exercisable and vested upon the date of such transaction.

XIII.            RIGHTS IN THE EVENT OF DEATH

If a Participant dies while employed by the Company, or within three months
after having retired with the consent of the Company, and without having fully
exercised his options, the executors or administrators, or legatees or heirs,
of his estate shall have the right to exercise such Options and to the extent
that such deceased Participant was entitled to exercise said Options on the
date of his death; provided, however, that in no event shall the Options be
exercisable more than ten (10) years from the date they were granted.

XIV.             NO OBLIGATIONS TO EXERCISE OPTION

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

XV.              NONASSIGNABILITY

Options shall not be transferable other than by will or by the law of descent
and distribution, and during a Participant's lifetime shall be exercisable only
by such Participant.

XVI.             LOSS OF RIGHT TO EXERCISE OPTIONS

A Participant or other person entitled to exercise Options under this Plan
shall forfeit such rights if the Participant violates a confidentiality
agreement or covenant not to compete with the Company whether contained within
individual Stock Option Agreements entered into between the Participant and the
Company by separate instrument.

XVII.            EFFECT OF CHANGE IN STOCK SUBJECT TO THE PLAN

The aggregate number of shares of Stock available for Options under the Plan,
the shares subject

                                      -4-
<PAGE>   5
to any Option, the price per share, shall all be proportionately adjusted for
any increase or decrease in the number of issued shares of Stock subsequent to
the effective date of the Plan resulting from (1) a subdivision or
consolidation of shares or any other capital adjustment, (2) the payment of a
stock dividend, or (3) other increase or decrease in such shares effected
without receipt of consideration by the Company, if the Company shall be the
surviving corporation in any merger or consolidation, any Option shall pertain,
apply and relate to the securities to which a holder of the number of shares
of Stock subject to the Option would have been entitled after the merger or
consolidation.

Upon dissolution or liquidation of the Company, or upon a merger or
consolidation in which the Company is not the surviving corporation, all
Options outstanding under the Plan shall terminate; provided, however, that (i)
any Options granted under the Plan and not previously exercised and vested
shall become fully exercisable and vested no later than the date of such
dissolution, merger or consolidation, and (ii) each Participant (and each other
person entitled under this Plan to exercise an Option) shall have the right,
immediately prior to such dissolution or liquidation, or such merger or
consolidation, to exercise such Participant's Options in whole or in part, but
only to the extent that such Options are otherwise exercisable under the terms
of this Plan.

XVIII.           AMENDMENT AND TERMINATION

The Board, by resolution, may terminate, amend, or revise the Plan with respect
to any shares as to which Options have not been granted. Neither the Board nor
the Committee may, without the consent of the holder of an Option, alter or
impair any Option previously granted under the Plan, except as authorized
herein. Unless sooner terminated, the Plan shall remain in effect for a period
of 10 years from the date of this amended and restated Plan's adoption by the
Board. Termination of the Plan shall not affect any Option previously granted.

XIX.             COMPLIANCE WITH LAW AND APPROVAL OF REGULATORY BODY

No Option shall be exercisable and no Stock will be delivered under this Plan
except in compliance with all applicable federal and state laws and
regulations, including, without limitation, compliance with all applicable
withholding tax requirements, if any, and with the rules of all domestic stock
exchanges on which the Stock may be listed.  Any stock certificates issued to
evidence the Stock as to which an Option is exercised may bear such legends and
statements as the Company shall deem advisable to assure compliance with
federal and state laws and regulations; the Company may, if it deems
appropriate, condition its grant of any Options hereunder upon receipt of the
following investment representation from the Participant or other person
authorized to exercise such Options under this Plan:

                 "I agree that any Stock of Medical Advisory Systems, Inc.
                 which I may acquire by virtue of this Stock Option shall be
                 acquired for investment purposes only and not with a view to
                 distribution or resale, and may not be transferred, sold,
                 assigned, pledged, hypothecated or otherwise disposed of by me
                 unless (i) a registration statement or post-effective
                 amendment to a registration statement under the Securities Act
                 of 1933, as amended, with respect to said Stock has become
                 effective so as to permit the sale or other disposition of
                 said shares by me; or (ii) there is presented to Medical
                 Advisory Systems, Inc. an opinion of counsel satisfactory to
                 Medical Advisory Systems, Inc.  to the effect that the sale or
                 other proposed disposition of said Stock by me may lawfully be
                 made

                                      -5-
<PAGE>   6
                 otherwise than pursuant to an effective registration statement
                 or post-effective amendment to a registration statement
                 relating to the said Stock under the Securities Act of 1933,
                 as amended."

No Option shall be exercisable, and no stock will be delivered under this Plan,
until the Company has obtained such consent or approval from the regulatory
body, federal or state, having jurisdiction over such matters as the Company
may deem advisable.  In the case of the exercise of an Option by someone other
than the Participant as permitted herein, the Company may require reasonable
evidence as to the ownership of such Option and may require such consents and
releases of taxing authorities as the Committee may deem advisable.

XX.              PRESERVATION OF SHARES OF STOCK

The Company during the term of this Plan, will at all times reserve and keep
available, and will seek or obtain from any regulatory body having jurisdiction
any requisite authority necessary to issue and to sell, the number of Shares of
Stock that shall be sufficient to satisfy the requirements of this Plan. The
inability of the Company to obtain from any regulatory body having jurisdiction
the authority deemed necessary by counsel for the Company for the lawful
issuance and sale of its stock hereunder shall relieve the Company of any
liability in respect of the failure to issue or sell Stock as to which the
requisite authority has not been obtained.

XXI.             EFFECTIVE DATE OF PLAN

The Plan was originally effective as of June 21, 1993; the date the Plan was
approved by the Board of Directors.  The terms of this amended and restated
Plan shall be effective March 1, 1998.

           Registration Rights Agreement, dated as of January 11, 2000, by and
between VCampus Corporation, a Delaware corporation ("Company"), and Mastech

                              W I T N E S S E T H:

           WHEREAS, Company and Purchaser have entered into that certain Stock

Agreement and to purchase, through its Mastech eVentures business unit, the
shares of Common Stock of the Company and the Warrant exercisable for Common
Stock of the Company, Company has agreed to provide registration rights with
respect thereto;

           NOW, THEREFORE, in consideration of the premises and the covenants
hereinafter contained, it is agreed as follows:

           1.    Definitions. Unless otherwise defined herein, terms used herein

following shall have the following respective meanings (such meanings being
equally applicable to both the singular and plural form of the terms defined):

           "Agreement" shall mean this Registration Rights Agreement, including

pursuant to the Purchase Agreement, the Warrant Shares, shares of Common Stock
hereafter acquired by Purchaser, and shares of Common Stock which Purchaser
hereafter obtains the right to acquire pursuant to any dividend, distribution,
stock split or similar transaction or rights to the extent that all of the
holders of the Common Stock received shares of Common Stock; provided, however,
that the shares of Common Stock or Warrant Shares shall only be treated as
Registrable Securities if and for so long as they have not been sold to or
through a broker or underwriter in a public distribution, or only until the date
on which all of the Registrable Securities can be disposed of in any three month
period pursuant to Rule 144 (or any similar or analogous rule under the
Securities Act of 1933).

           "Registration Statement" shall mean a registration statement filed by
the Company with the U.S. Securities and Exchange Commission for a public

in a transaction of the type referred to in Rule 145 under the Securities Act or
to employees of Company pursuant to any employee benefit plan, respectively).

           2.    Required Registration. Subject to the terms of this Section 2
and Section 5, after receipt of a written request from the holders of
Registrable Securities requesting that Company effect a registration under the
Securities Act covering at least 30% of the Registrable Securities then
outstanding, and specifying the intended method or method of disposition
thereof, Company shall promptly notify all Holders in writing of the receipt of
such request and each such Holder, in lieu of exercising its rights under
Section 3 may elect (by written notice sent to Company within ten (10) Business
Days from the date of such Holder's receipt of the aforementioned Company's
notice) to have Registrable Securities included in such registration thereof
pursuant this Section 2. Thereupon Company shall, as expeditiously as possible,
use its best efforts to effect the registration under the Securities Act of all
shares of Registrable Securities which Company has been so requested to register
by such Holders for sale, all to the extent required to permit the disposition
(in accordance with the intended method or methods thereof, as aforesaid) of the
Registrable Securities so registered; provided, however, that Company shall not
be required to effect more than one (1) registration per year of Registrable
Securities pursuant to this Section 2 and a total of five (5) registrations of
Registrable Securities pursuant to this Section 2 during the term of this
Agreement (excluding a Registration Statement on Form S-3 (or other comparable

Securities in one distribution or from time to time in the manner contemplated
by Rule 415 of the Securities Act (a "Shelf Registration Statement")). During
the two-year period following the date of this Agreement, the Company will be
permitted to satisfy its obligations under this Section 2 by filing a Shelf

the

                                       2
<PAGE>   3

offer and sale of Registrable Securities during the two year period following
the date of this Agreement, the Holders may require the Company to register
Registrable Securities on any applicable form including Form S-1 (or its
successor form). The Company shall not be required to file a Registration
Statement at a time when a Shelf Registration Statement covering Registrable
Securities is then in effect.

           3.    Incidental Registration. If Company at any time proposes to
file on its behalf a registration statement under the Securities Act on any form
(other than a Registration Statement on Form S-4 or S-8 or any successor form
for securities to be offered in a transaction of the type referred to in Rule
145 under the Securities Act or to employees of Company pursuant to any employee
benefit plan, respectively) for the general registration of securities (an
"Incidental Registration Statement"), it will give written notice to all Holders
at least 15 days before the initial filing with the SEC of such Incidental
Registration Statement, which notice shall set forth the intended method of
disposition of the securities proposed to be registered by Company. The notice
shall offer to include in such filing the aggregate number of shares of
Registrable Securities as such Holders may request.

           Each Holder desiring to have Registrable Securities registered under
this Section 3 shall advise Company in writing within 10 Business Days after the
date of receipt of such offer from Company, setting forth the amount of such
Registrable Securities for which registration is requested. Company shall
thereupon include in such filing the number of shares of Registrable Securities
for which registration is so requested, subject to the next sentence, and shall
use its best efforts to effect registration under the Securities Act of such
shares. In connection with any registration subject to this Section 3, which is
to be effected in a firm commitment underwriting, Company will not be required
to include Registrable Securities in such underwriting unless the Holder of such
Registrable Securities accepts the terms and conditions of the underwriting
agreement which is agreed upon between Company and the managing underwriter
selected by Company, so long as such underwriting agreement conforms to industry
standards and practices and the obligations and liabilities imposed on the
Holders under such agreement are customary for the stockholders selling
securities in an underwritten offering. If the managing underwriter of a
proposed public offering shall advise Company in writing that, in its opinion,
the distribution of the Registrable Securities requested to be included in the
registration concurrently with the securities being registered by Company would
materially and adversely affect the distribution of such securities by Company,
then all selling security holders with incidental registration rights shall
reduce the amount of securities each intended to distribute through such
offering on a pro rata basis. Except as otherwise provided in Section 5, all
expenses of such registration shall be borne by Company. The Company shall have
the right to terminate or withdraw any Registration Statement initiated under
this Section 3 prior to the effectiveness of such Registration Statement whether
or not the Holders have elected to include Registrable Securities in such
Registration Statement.

           4.    Registration Procedures. If the Company is required by the
provisions of Section 2 or 3 to use its best efforts to effect the registration
of any of its securities under the Securities Act, Company will, as
expeditiously as possible:

                 (a)   prepare and file with the SEC a Registration Statement
with respect to such securities and use its best efforts to cause such
Registration Statement to become and remain effective for a period of time
required for the disposition of such securities by the holders thereof, but not
to exceed 120 days (or, with respect to any underwritten offering, such shorter
period as the underwriters need to complete the distribution of the registered
offering or, with respect to a shelf Registration Statement on a form under the
Securities Act relating to the offer and sale of Registrable Securities from
time to time in accordance with Rule 415, such longer period as may be required
to dispose of the Registrable Securities covered by such Registration
Statement);

                 (b)    prepare and file with the SEC such amendments and
supplements to such Registration Statement and the prospectus used in connection
therewith as may be necessary to keep such Registration Statement effective and
to comply with the provisions of the Securities Act with respect to the sale or
other disposition of all securities covered by such Registration Statement
until, in the case of an Incidental Registration Statement filed pursuant to
Section 3, the earlier of such time as all of such securities have been disposed
of in a public offering or the expiration of 120 days, or in the case of a
Registration Statement filed pursuant to Section 2, such time as is set forth in
Section 4(a);

                 (c)    furnish, to such selling security holders such number of
copies of a summary prospectus or other prospectus, including a preliminary
prospectus, in conformity with the requirements of the Securities Act, and such
other documents, as such selling security holders may reasonably request;

                 (d)    use its best efforts to register or qualify the
securities covered by such Registration Statement under such other securities or
blue sky laws of such jurisdictions within the United States and Puerto Rico as
each holder of such securities shall request (provided, however, that Company
shall not be obligated to qualify as a foreign corporation to do business under
the laws of any jurisdiction in which it is not then qualified or to file any
general consent to service or process), and do such other reasonable acts and
things as may be required of it to enable such holder to consummate the
disposition in such jurisdiction of the securities covered by such Registration
Statement;

                 (e)    furnish, at the request of any Holder requesting
registration of Registrable Securities, on the date that such shares of
Registrable Securities are delivered to the underwriters for sale pursuant to
such registration or, if such Registrable Securities are not being sold through
underwriters, on the date that the Registration Statement with respect to such
shares of Registrable Securities becomes effective, (1) an opinion, dated such
date, of the independent counsel representing Company for the purposes of such
registration, addressed to the underwriters, if any, and if such Registrable
Securities are

                                       4
<PAGE>   5
not being sold through underwriters, then to the Holders making such request, in
customary form and covering matters of the type customarily covered in such
legal opinions; and (2) a comfort letter dated such date, from the independent
certified public accountants of Company, addressed to the underwriters, if any,
and if such Registrable Securities are not being sold through underwriters, then
to the Holder making such request and, if such accountants refuse to deliver
such letter to such Holder, then to Company, in a customary form and covering
matters of the type customarily covered by such comfort letters and as the
underwriters or such Holder shall reasonably request. Such opinion of counsel
shall additionally cover such other legal matters with respect to the
registration in respect of which such opinion is being given as the Holders of a
majority of the Registrable Securities being registered may reasonably request.
Such letter from the independent certified public accountants shall additionally
cover such other financial matters (including information as to the period
ending not more than five Business Days prior to the date of such letter) with
respect to the registration in respect of which such letter is being given as
the Holders of a majority of the Registrable Securities being so registered may
reasonably request;

                 (f)    enter into customary agreements (including an
underwriting agreement in customary form) and take such other actions as are
reasonably required in order to expedite or facilitate the disposition of such
Registrable Securities;

                 (g)    otherwise use its best efforts to comply with all
applicable rules and regulations of the SEC, and make available to its security
holders, as soon as reasonably practicable, but not later than 18 months after
the effective date of the Registration Statement, an earnings statement covering
the period of at least 12 months beginning with the first full month after the

                 (h)    give written notice to Holders:

                        (i)    when such Registration Statement or any amendment
        thereto has been filed with the SEC and when such Registration Statement
        or any posteffecive amendment thereto has become effective;

                        (ii)   of any request by the SEC for amendments or
        supplements to such Registration Statement or the prospectus included
        therein or for additional information;

                        (iii)  of the issuance by the SEC of any stop order
        suspending the effectiveness of such Registration Statement or the
        initiation of any proceedings for that purpose;

                        (iv)   of the receipt by Company or its legal counsel of
        any notification with respect to the suspension of the qualification of
        the Common

        Stock for sale in any jurisdiction or the initiation or threatening of
        any proceeding for such purpose; and

                        (v)    of the happening of any event that requires
        Company to make changes in such Registration Statement or the prospectus
        in order to make the statements therein not misleading (which notice
        shall be accompanied by an instruction to suspend the use of the
        prospectus until the requisite changes have been made);

                 (i)    use its best efforts to prevent the issuance or obtain
the withdrawal of any order suspending the effectiveness of such Registration
Statement at the earliest possible time;

                 (j)    furnish to each Holder, without charge, at least one
copy of such Registration Statement and any post-effective amendment thereto,
including financial statements and schedules, and, if the Holder so requests in
writing, all exhibits (including those, if any, incorporated by reference);

                 (k)    cooperate with the Holders to facilitate the timely
preparation and delivery of certificates representing the Registrable Securities
to be sold free of any restrictive legends and in such denominations and
registered in such names as the Holders may request a reasonable period of time
prior to sales of the Registrable Securities;

                 (l)    upon the occurrence of any event contemplated by Section
4(h)(v) above, promptly prepare a post-effective amendment to such Registration
Statement or a supplement to the related prospectus or file any other required
document so that, as thereafter delivered to Holders, the prospectus will not
contain an untrue statement of a material fact or omit to state any material
fact necessary to make the statements therein, in light of the circumstances
under which they were made, not misleading. If the Company notifies the Holders
in accordance with Section 4(h)(v) above to suspend the use of the prospectus
until the requisite changes to the prospectus have been made, then the Holders
shall suspend use of such prospectus, and the period of effectiveness of such
Registration Statement provided for above shall each be extended by the number
of days from and including the date of the giving of such notice to Holders
shall have received such amended or supplemented prospectus pursuant to this
Section 4(l);

                 (m)    (i) make reasonably available for inspection by the
Holders, any underwriter participating in any disposition pursuant to such
Registration Statement and any attorney, accountant or other agent retained by
the Holders or any such underwriter all relevant financial and other records,
pertinent corporate documents and properties of the Company and (ii) cause the
Company's officers, directors and employees to supply all relevant information
reasonably requested by the Holders or any such underwriter, attorney,
accountant or agent in connection with the registration; provided that the
foregoing inspection and information gathering shall be coordinated on behalf of
the

                                       6
<PAGE>   7

Purchaser by Purchaser and on behalf of the other parties, by one counsel
designated by and on behalf of such other parties as described in Section 4; and

                 (n)    in connection with any underwritten offering, make
appropriate officers of Company reasonably available to the selling security
holders for meetings with prospective purchasers of the Registrable Securities
and prepare and present to potential investors customary "road show" material in
a manner consistent with other new issuances of securities similar to the
Registrable Securities, in connection with any proposed sale of the Registrable
Securities in an aggregate offering of at least $10 million.

           It shall be a condition precedent to the obligation of Company to
take any action pursuant to this Agreement in respect of the securities which
are to be registered at the request of any Holder that such Holder shall furnish
to Company such information regarding the securities held by such Holder and the
intended method of disposition thereof as Company shall reasonably request and
as shall be required in connection with the action taken by Company.

           5.    Expenses. All expenses incurred in complying with this
Agreement, including, without limitation, all registration and filing fees
(including all expenses incident to filing with the NASD), printing expenses,

majority of the shares being registered), expenses of any special audits
incident to or required by any such registration and expenses of complying with
the securities or blue sky laws of any jurisdiction pursuant to Section 4(d),
shall be paid by Company, except that:

                 (a)    All such expenses (including costs associated with
including shares of Company Common Stock held by other parties, other than
employees or directors of the Company, who have registration rights of the type
described in Section 3 hereof) in connection with a Registration Statement filed
prior to the first anniversary of the date of this Agreement pursuant to Section
2 shall be paid by the selling Holders; provided that the Holders shall not be
required to pay aggregate expenses in excess of $50,000; and

                 (b)    all such expenses in connection with any amendment or
supplement to a Registration Statement or prospectus required to be filed
pursuant to Section 3 which is filed more than 180 days after the effective date
of such Registration Statement because any Holder has not effected the
disposition of the securities requested to be registered shall be paid by such
Holder; and

                 (c)    Company shall not be liable for any fees, discounts or
commissions to any underwriter or any fees or disbursements of counsel for any
underwriter in respect of the securities sold by such Holder.

           6.    Indemnification and Contribution.

                 (a)    In the event of any registration of any Registrable
Securities under the Securities Act pursuant to this Agreement, Company shall
indemnify and hold harmless the holder of such Registrable Securities, such
holder's directors and officers, and each other person (including each
underwriter) who participated in the offering of such Registrable Securities and
each other person, if any, who controls such holder or such participating person
within the meaning of the Securities Act, against any losses, claims, damages or
liabilities, joint or several, to which such holder or any such director or
officer or participating person or controlling person may become subject under
the Securities Act or any other statute or at common law, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon (i) any alleged untrue statement of any material fact
contained, on the effective date thereof, in any Registration Statement under
which such securities were registered under the Securities Act, any preliminary
prospectus or final prospectus contained therein, or any amendment or supplement
thereto, or (ii) any alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
and shall reimburse such holder or such director, officer or participating
person or controlling person for any legal or any other expenses reasonably
incurred by such holder or such director, officer or participating person or
controlling person in connection with investigating or defending any such loss,
claim, damage, liability or action; provided, however, that Company shall not be
liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon any actual or alleged untrue statement
or actual or alleged omission made in such Registration Statement, preliminary
prospectus, prospectus or amendment or supplement in reliance upon and in
conformity with written information furnished to Company by such holder
specifically for use therein or (in the case of any underwritten offering) so
furnished for such purposes by any underwriter. Such indemnity shall remain in
full force and effect regardless of any investigation made by or on behalf of
such holder or such director, officer or participating person or controlling
person, and shall survive the transfer of such securities by such holder.

                 (b)    Each Holder, by acceptance hereof, agrees to indemnify
and hold harmless Company, its directors and officers and each other person, if
any, who controls Company within the meaning of the Securities Act against any
losses, claims, damages or liabilities, joint or several, to which Company or
any such director or officer or any such person may become subject under the
Securities Act or any other statute or at common law, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon information in writing provided to Company by such Holder
specifically for use in the following documents and contained, on the effective
date thereof, in any Registration Statement under which securities were
registered under the Securities Act at the request of such holder, any
preliminary prospectus or final prospectus contained therein, or any amendment
or supplement thereto. Notwithstanding the provisions of this paragraph (b) or
paragraph (c) below, no Holder shall be required to indemnify any person
pursuant to this Section 6 or to contribute pursuant to paragraph (c)

                                       8
<PAGE>   9

below in an amount in excess of the amount of the aggregate net proceeds
received by such Holder in connection with any such registration under the
Securities Act.

                 (c)    If the indemnification provided for in this Section 6
from the indemnifying party is unavailable to an indemnified party hereunder in
respect of any losses, claims, damages, liabilities or expenses referred to
therein, then the indemnifying party, in lieu of indemnifying such indemnified
party, shall contribute to the amount paid or payable by such indemnified party
as a result of such losses, claims, damages, liabilities or expenses in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party and indemnified parties in connection with the actions which resulted in
such losses, claims, damages, liabilities or expenses, as well as any other
relevant equitable considerations. The relative fault of such indemnifying party
and indemnified parties shall be determined by reference to, among other things,
whether any action in question, including any untrue or alleged untrue statement
of a material fact or omission or alleged omission to state a material fact, has
been made by, or relates to information supplied by, such indemnifying party or
indemnified parties, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such action. The amount paid
or payable by a party as a result of the losses, claims, damages, liabilities
and expenses referred to above shall be deemed to include any legal or other
fees or expenses reasonably incurred by such party in connection with any
investigation or proceeding.

           The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 6(c) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding paragraph.
No Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation.

           7.    Certain Limitations on Registration Rights. Notwithstanding the
other provisions of this Agreement:

                 (a)    Company shall have the right to delay the filing or
effectiveness of, or by written notice require the Holders to cease sales of
Registrable Securities pursuant to, a Registration Statement required pursuant
to Section 2 hereof during one or more periods aggregating not more than 60 days
in any twelve-month period (such period or periods, the "Suspension Period") in
the event that (i) Company would, in accordance with the advice of its counsel,
be required to disclose in the prospectus information not otherwise then
required by law to be publicly disclosed, (ii) in the judgment of Company's
Board of Directors, there is a reasonable likelihood that such disclosure, or
any other action to be taken in connection with the prospectus, would materially
and adversely affect any existing or prospective material business situation,
transaction or negotiation or otherwise materially and adversely affect Company,
or (iii) the Registration Statement can no longer be used under the Securities
Act; provided that the

                                       9
<PAGE>   10

period of effectiveness of the Registration Statement pursuant to Section 2
shall be extended by the length of any such Suspension Period;

                 (b)    Notwithstanding Section 7(b) hereof, Company agrees that
it shall not impose a Suspension Period during the 30-day period following the
date on which the Registration Statement is first declared effective by the SEC
(the "30-day Period") as a result of any activity initiated by Company, or in
response to any proposal, unless Company's Board of Directors determines in good
faith that it is required to impose a Suspension Period by law during such
30-day Period. To the extent Company imposes a Suspension Period during such
30-day Period as a result of such determination by Company's Board of Directors,
Company shall not, for such additional number of consecutive days following the
termination of such Suspension Period, impose an additional Suspension Period,
so as to provide the Holders with a total of 30 days without a Suspension
Period; and

                 (c)    If Company suspends the Registration Statement or
requires the Holders to cease sales of the Common Stock pursuant to paragraph
(a) above, Company shall, as promptly as practicable following the termination
of the circumstances which entitled Company to do so, take such action as may be
necessary to reinstate the effectiveness of the Registration Statement and/or
give written notice to all Holders authorizing them to resume sales pursuant to
the Registration Statement. If, as a result thereof, the prospectus included in
the Registration Statement has been amended to comply with the requirements of
the Securities Act, Company shall enclose such revised prospectus with a notice
to Holders given pursuant to this paragraph (c), and the Shareholders shall make
no offers or sales of shares pursuant to such Registration Statement other than
by means of such revised prospectus.

           8.    Selection of Managing Underwriters. The managing underwriter or
underwriters for any offering of Registrable Securities to be registered
pursuant to Section 2 in an underwritten public offering shall be of recognized
national standing selected by the holders of a majority of the shares being so
registered, and shall be reasonably acceptable to Company.

           9.    Restrictions on Sale After Public Offering. Except for
transfers made in transactions exempt from the registration requirements under
the Securities Act (other than Rule 144 thereunder), Company and each Holder
hereby agree not to offer, sell, contract to sell or otherwise dispose of any of
their Registrable Securities within 120 days after the date of any final
prospectus relating to the public offering of Common Stock, if underwritten,
whether by Company or by any Holders, except pursuant to such prospectus or with
the written consent of the managing underwriter or underwriters for such
offering.

           10.   Miscellaneous.

                 (a)    No Inconsistent Agreements. From and after the date of
this Agreement, the Company shall not, without the prior written consent of the
Majority

                                       10
<PAGE>   11

Holders, enter into any agreement with any holder or prospective holder of any
securities of the Company which would grant such holder or prospective holder of
any securities of the Company the right to require the Company to initiate any
registration of any securities of the Company (i) that is inconsistent with or
superior to the rights of the Holders of Registrable Shares provided in this
Agreement or (ii) that would require the exclusion of Registrable Shares held by
the Holders from such a registration beyond any such exclusion contemplated by
this Agreement. This Paragraph 10(a) shall not limit the right of the Company to
enter into any agreements with any holder or prospective holder of any
securities of the Company giving such holder or prospective holder the right to
require the Company, upon any registration of any of its securities, to include,
among the securities which the Company is then registering, securities owned by
such holder if such rights are subordinate to the rights of a Holder of
Registrable Shares.

                 (b)    Remedies. Each Holder, in addition to being entitled to
exercise all rights granted by law, including recovery of damages, will be
entitled to specific performance of its rights under this Agreement. Company
agrees that monetary damages would not be adequate compensation for any loss
incurred by reason of a breach by it of the provisions of this Agreement and
hereby agrees to waive the defense in any action for specific performance that a
remedy at law would be adequate. In any action or proceeding brought to enforce
any provision of this Agreement or where any provision hereof is validly
asserted as a defense, the successful party shall be entitled to recover
reasonable attorneys' fees in addition to any other available remedy.

                 (c)    Amendments and Waivers. Except as otherwise provided
herein, the provisions of this Agreement may not be amended, modified or
supplemented, and waivers or consents to departure from the provisions hereof
may not be given without the written consent of the Majority Holders and the
Company.

                 (d)    Notice Generally. Any notice, demand, request, consent,
approval, declaration, delivery or other communication hereunder to be made
pursuant to the provisions of this Agreement shall be sufficiently given or made
if in writing and either delivered in person with receipt acknowledged or sent
