of the Registrant to be delivered to holders of common stock, warrants, options

consummation of the merger of AHT Corporation with a subsidiary of the
Registrant, assuming the exercise of all outstanding warrants, options and other
rights to purchase or acquire shares of AHT Corporation common stock prior to
the consummation of the merger. The exact number of shares to be issued will be
calculated based upon the average trading price of the common stock of the
Registrant over a specified period, subject to collar provisions described in
the merger agreement. The number of shares of common stock of the Registrant to
be registered hereunder was calculated by multiplying an aggregate of 15,669,504
shares, options, warrants and other rights to purchase or acquire shares of AHT
Corporation to be received or cancelled in the merger (calculated as described
in footnote 2 below) by the maximum exchange rate provided under the merger
agreement. The Registrant does not expect the number of shares of its common
stock actually issued in the merger to exceed this number.

         (2) Estimated solely for the purpose of calculating the registration
fee pursuant to Rule 457(f)(1) promulgated under the Securities Act of 1933,
based upon an aggregate of 15,669,504 shares, options, warrants and other rights
to purchase or acquire shares of AHT Corporation to be received or cancelled in
the merger referred to in this Registration Statement, and $1.266, the average
of the high and low sales prices for a share of the common stock of AHT
Corporation, as reported on Nasdaq National Market on July 28, 2000. The
15,669,504 shares are comprised of (a) 11,130,449 shares of AHT Corporation
outstanding as of June 30, 2000; (b) 1,501,625 shares issuable pursuant to
incentive stock options; (c) 851,489 shares issuable pursuant to stock purchase
warrants; (d) up to 1,897,218 shares issuable in connection with settlement of
certain litigation, based upon the current trading prices of the common stock of
AHT Corporation and the maximum exchange rate provided under the merger
agreement; and (e) up to 288,723 shares issuable pursuant to certain severance
benefits payable to executive officers of AHT Corporation.

         THE REGISTRANT HEREBY AMENDS THIS REGISTRATION STATEMENT ON SUCH DATE
OR DATES AS MAY BE NECESSARY TO DELAY ITS EFFECTIVE DATE UNTIL THE REGISTRANT
SHALL FILE A FURTHER AMENDMENT WHICH SPECIFICALLY STATES THAT THIS REGISTRATION
STATEMENT SHALL THEREAFTER BECOME EFFECTIVE IN ACCORDANCE WITH SECTION 8(A) OF

BIOSHIELD TECHNOLOGIES, INC.                                    AHT CORPORATION


                        JOINT PROXY STATEMENT/PROSPECTUS
                 MERGER PROPOSED -- YOUR VOTE IS VERY IMPORTANT

         The boards of directors of BioShield Technologies, Inc. and AHT
Corporation have agreed to a merger in which BioShield, through its wholly owned
subsidiary AHT Acquisition Corp., will acquire AHT. This proposed merger will
join BioShield with AHT, a national provider of internet-based e-commerce
solutions for clinical laboratories, pharmacy benefit managers, pharmacies and
physicians, and will allow BioShield to integrate AHT's business-to-business
laboratory and prescription transaction management operations with BioShield's
eMD internet healthcare subsidiary to create one of the industry's leading
e-healthcare companies.

         In the merger, AHT will merge with and into AHT Acquisition Corp., with
AHT being the surviving corporation. Holders of AHT common stock will receive
$1.75 worth of BioShield common stock in exchange for each outstanding share of
AHT common stock if the average closing trading price of a share of BioShield
common stock, as determined in accordance with the merger agreement, is between
$6.00 and $18.00 per share. The exchange ratio outside of the collar will be
fixed. AHT stockholders will receive .29167 shares of BioShield common stock for
each AHT share if the BioShield stock price is $6.00 or less and .09722 shares
of BioShield common stock for each AHT share if the BioShield stock price is
$18.00 or more.

         We estimate, based on the current trading price of the BioShield common
stock, that approximately 3.1 million shares of BioShield common stock will be
issued, or issuable upon the exercise of options, warrants or other rights we
expect to be outstanding, to AHT stockholders upon completion of the merger.
These shares will represent approximately 20% of the outstanding shares of
common stock of BioShield after the merger on a fully diluted basis. The shares
of BioShield common stock held by BioShield stockholders before the merger will
represent approximately 80% of the outstanding shares of BioShield common stock
after the merger on a fully diluted basis. BioShield stockholders will continue
to own their existing shares after the merger.

         We cannot complete the merger unless BioShield stockholders approve the
issuance of BioShield common stock necessary to complete the merger and AHT
stockholders adopt and approve the merger agreement and the merger. This
document describes those meetings and the merger. YOUR VOTE IS VERY IMPORTANT.
Whether or not you plan to attend your stockholder meeting, please take the time
to vote by completing and mailing the enclosed proxy card to us. If you date and
mail your proxy card without indicating how you want to vote, proxies returned
by BioShield stockholders will be counted as a vote "FOR" the issuance of the
BioShield common stock to be issued in connection with the merger and proxies
returned by AHT stockholders will be counted as a vote "FOR" adoption and
approval of the merger agreement and the merger. If you do not return your card,
or if you do not instruct your broker how to vote any shares held for you in
"street name", the effect will be the same as a vote by BioShield stockholders
against the issuance of BioShield common stock and a vote by AHT stockholders
against adoption and approval of the merger agreement and the merger.

         The dates, times and places of the annual meeting for BioShield and the
special meeting for AHT are as follows:

         In addition to the proposal to issue the shares of BioShield common
stock necessary to complete the merger with AHT, BioShield stockholders will be
asked to vote on other proposals, including the election of five directors to
serve on BioShield's board of directors.

         WE ENTHUSIASTICALLY SUPPORT THIS COMBINATION OF OUR COMPANIES AND JOIN
WITH THE OTHER MEMBERS OF OUR BOARDS OF DIRECTORS IN RECOMMENDING THAT YOU VOTE
IN FAVOR OF THE MERGER.

the presence of a quorum at the annual meeting. As a result, abstentions and
broker non-votes will have the same effect as a vote against the first, third,

                              JOINT PROXY STATEMENT

                                    ---------

                          BIOSHIELD TECHNOLOGIES, INC.

                                   PROSPECTUS

                                    --------


         The boards of directors of BioShield Technologies, Inc. and AHT
Corporation have agreed to a merger in which BioShield, through its wholly owned
subsidiary, AHT Acquisition Corp., will acquire AHT. This proposed merger will
join BioShield with AHT, a national provider of internet-based e-commerce
solutions for clinical laboratories, pharmacy benefit managers, pharmacies and
physicians, and will allow BioShield to integrate AHT's business-to-business
laboratory and prescription transaction management operations with BioShield's
eMD internet healthcare subsidiary to create one of the industry's leading
e-healthcare companies.

         This joint proxy statement is being provided to you in connection with
the merger, and also constitutes the prospectus of BioShield covering the shares
of BioShield common stock to be issued upon completion of the merger.

         In the merger, AHT will merge with and into AHT Acquisition Corp., with
AHT being the surviving corporation. Holders of AHT common stock will receive
$1.75 worth of BioShield common stock in exchange for each outstanding share of
AHT common stock if the average closing trading price of a share of BioShield
common stock, as determined in accordance with the merger agreement, is between
$6.00 and $18.00 per share. The exchange ratio outside of the collar will be
fixed. AHT stockholders will receive .29167 shares of BioShield common stock for
each AHT share if the BioShield stock price is $6.00 or less and .09722 shares
of BioShield common stock for each AHT share if the BioShield stock price is
$18.00 or more.

         We estimate, based on the current trading price of the BioShield common
stock, that approximately 3.1 million shares of BioShield common stock will be
issued, or issuable upon the exercise of options, warrants or other rights we
expect to be outstanding, to AHT stockholders upon completion of the merger.
These shares will represent approximately 20% of the outstanding shares of
common stock of BioShield after the merger on a fully diluted basis. The shares
of BioShield common stock held by BioShield stockholders before the merger will
represent approximately 80% of the outstanding shares of BioShield common stock
after the merger on a fully diluted basis. BioShield stockholders will continue
to own their existing shares after the merger.

         YOU SHOULD CAREFULLY CONSIDER THE RISK FACTORS BEGINNING ON PAGE __ OF
THIS JOINT PROXY STATEMENT/PROSPECTUS BEFORE DETERMINING HOW TO CAST YOUR VOTE.

         Neither the Securities and Exchange Commission nor any state securities
commission has approved or disapproved of the securities to be issued under this
joint proxy statement/prospectus or determined if this joint proxy
statement/prospectus is truthful or complete. Any representation to the contrary
is a criminal offense.

statements, including statements as to industry trends, future economic
performance, anticipated profitability, anticipated revenues and expenses,

in their entirety by the cautionary statements contained or referred to in this
section.

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q:       WHAT ARE BIOSHIELD AND AHT PROPOSING? (page __)

A:       BioShield has entered into a merger agreement with AHT pursuant to
         which BioShield is proposing, through AHT Acquisition Corp., a wholly
         owned subsidiary of BioShield, to acquire AHT. Under the terms of the
         merger agreement, AHT Acquisition Corp. will merge with AHT. As a
         result of the merger, AHT will become a wholly owned subsidiary of
         BioShield.

Q:       WHAT WILL HOLDERS OF AHT COMMON STOCK RECEIVE IN THE MERGER? (page __)

A:       Holders of shares of AHT common stock will receive $1.75 worth of
         BioShield common stock if the average closing trading price of
         BioShield common stock, as determined in accordance with the merger
         agreement, is between $6.00 and $18.00 per share. Holders of shares of
         AHT common stock will receive .29167 shares of BioShield common stock
         if the average closing trading price of BioShield common stock is $6.00
         or less and .09722 shares of BioShield common stock if the average
         closing trading price of BioShield common stock is $18.00 or more.

         BioShield will not issue fractional shares of BioShield common stock.
         Instead, cash will be paid with respect to fractional shares. For
         example, if the average closing trading price of BioShield common stock
         is $10.00, the exchange ratio will equal .17500 and a holder of 100
         shares of AHT common stock would receive 17 shares of BioShield common
         stock, plus a cash payment equal to the value of 0.50 of a share of
         BioShield common stock, or $5.00.


Q:       WHAT IS THE "EXCHANGE RATIO?" (page __)

A:       The exchange ratio is the fraction of a share of BioShield common stock
         into which each share of AHT common stock will be converted upon
         completion of the merger. If the average closing trading price of
         BioShield common stock, as determined in accordance with the merger
         agreement, is between $6.00 and $18.00 per share, the exchange ratio
         will fluctuate so that holders of shares of AHT common stock will
         receive $1.75 worth of BioShield common stock.

         If the average closing trading price of BioShield common stock is $6.00
         or less or $18.00 or more, the exchange ratio will be fixed at .29167
         and .09722, respectively. Please note that because the exchange ratio
         may become fixed and the market price of the shares of BioShield common
         stock that AHT stockholders will receive may fluctuate, AHT
         stockholders cannot be sure of the market value of the shares of
         BioShield common stock they will receive in the merger.


Q:       HOW CAN I FIND OUT THE FINAL EXCHANGE RATIO? (page __)

A:       Before the date of the AHT special meeting, we will notify you by
         issuing a press release announcing the final exchange ratio and filing
         that press release with the SEC. AHT stockholders can call Arthur Dague
         at (914) 524-4200 for the average BioShield trading price for the
         preceding ten trading days and the exchange ratio that would be in
         effect based on that price. For more information on the exchange ratio
         and for a table setting forth a range of average BioShield trading
         prices, the resulting exchange ratio and illustrations of the value you
         would receive for your AHT shares, please see "The exchange ratio"
         beginning on page [ ].


Q:       WHAT WILL HOLDERS OF BIOSHIELD COMMON STOCK RECEIVE IN THE MERGER?
         (page __)

A:       Holders of BioShield common stock will retain the shares of BioShield
         common stock that they currently own and these shares will remain
         unchanged. However, as a result of the merger, they will own shares of
         a larger, more diversified company, as more fully described in this
         joint proxy statement/prospectus.


                                        2
<PAGE>   15

Q:       IS BIOSHIELD'S FINANCIAL CONDITION RELEVANT TO MY DECISION TO VOTE IN
         FAVOR OF THE MERGER? (page __)

A:       Yes. In the merger, shares of AHT common stock will be exchanged for
         shares of BioShield common stock, so AHT stockholders should consider
         BioShield's financial condition before deciding to become one of
         BioShield's stockholders through the merger. In considering BioShield's
         financial condition, AHT stockholders should review the documents
         incorporated by reference in this joint proxy statement/prospectus

Q:       DO THE BOARDS OF DIRECTORS OF BIOSHIELD AND AHT RECOMMEND VOTING IN
         FAVOR OF THE MERGER? (pages __ and __)

A:       Yes.

         -        After careful consideration, BioShield's board of directors
                  unanimously recommends that BioShield stockholders vote in
                  favor of the issuance of shares of BioShield common stock in
                  connection with the merger.

         -        After careful consideration, AHT's board of directors
                  unanimously recommends that AHT stockholders vote in favor of
                  adoption and approval of the merger agreement and the merger.


Q:       HAVE BIOSHIELD AND AHT RECEIVED FAVORABLE OPINIONS FROM THEIR FINANCIAL
         ADVISORS CONCERNING THE MERGER? (pages __ and __)

A:       In deciding to approve the merger, BioShield's board of directors
         considered the opinion from its financial advisor, Gruntal & Co.,
         L.L.C., as to the fairness, from a financial point of view, to
         BioShield's common stockholders of the consideration to be paid to
         AHT's common stockholders in the merger. In deciding to approve the
         merger, AHT's board of directors considered the opinion from its
         financial advisor, Chase H&Q (a division of Chase Securities Inc.), as
         to the fairness, from a financial point of view, based on and


                                        3
<PAGE>   16

         subject to the matters described in its opinion, of the consideration
         to be received by the holders of AHT common stock in the merger.

         The full text of the written opinions of the financial advisors is
         attached to this joint proxy statement/prospectus as Appendix B and
         Appendix C. You should read these opinions carefully and completely for
         a description of the assumptions made, matters considered and the
         limitations of the review the advisors conducted. The opinion of
         Gruntal is directed to the BioShield board of directors, and the
         opinion of Chase H&Q is directed to the AHT board of directors. These
         opinions are not a recommendation as to how BioShield stockholders or
         AHT stockholders should vote with respect to any matter relating to the
         proposed merger.


Q:       WHAT STOCKHOLDER APPROVALS ARE NEEDED TO COMPLETE THE MERGER? (page __)

A:       For BioShield, the affirmative vote of the holders of a majority of the
         outstanding shares of BioShield common stock is required to approve the
         issuance of BioShield common stock necessary to complete the merger.

         For AHT, the affirmative vote of the holders of a majority of the
         outstanding shares of AHT common stock is required to adopt and approve
         the merger agreement and the merger.


Q:       IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER
         VOTE MY SHARES FOR ME? (page __)

A:       Your broker will vote your shares only if you provide instructions to
         your broker on how to vote. You should follow the directions provided
         by your broker regarding how to instruct your broker to vote your
         shares. Without instructions, your shares will not be voted on the
         proposed merger, which will have the same effect as voting against the
         proposed merger.


Q:       WHAT IF I DON'T VOTE? (pages __ and __)

A:       For BioShield stockholders, if you fail to vote or if you respond and
         abstain from voting it will have the same effect as a vote against the
         issuance of BioShield common stock in connection with the merger. If
         you return your proxy and do not indicate how you want to vote, your
         proxy will be counted as a vote to approve the issuance of BioShield
         common stock.

         For AHT stockholders, if you fail to vote or if you respond and abstain
         from voting it will have the same effect as a vote against the merger
         agreement and the merger. If you return your proxy and do not indicate
         how you want to vote, your proxy will be counted as a vote to adopt and
         approve the merger agreement and the merger.


Q:       CAN I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD? (page
         __)

A:       Yes. There are three ways in which you may revoke your proxy and change
         your vote. First, you may send a written notice to the party to whom
         you submitted your proxy stating that you would like to revoke your
         proxy. Second, you may complete and submit a new proxy card. Third, you
         may attend the BioShield annual meeting or the AHT special meeting, as
         applicable, and vote in person. Simply attending the special meeting,
         however, will not revoke your proxy. If you have instructed a broker to
         vote your shares, you must follow directions received from your broker
         to change your vote.

<PAGE>   17
Q:       WHAT OTHER MATTERS WILL BE VOTED ON AT THE MEETINGS? (page __)

A:       We do not expect to ask AHT stockholders to vote on any matter other
         than the merger at the AHT special meeting. At the BioShield annual
         meeting, in addition to voting on the issuance of shares of BioShield
         common stock to effect the merger, BioShield stockholders will be asked
         to vote upon a number of other proposals, including the election of
         five directors to serve on BioShield's board of directors.


Q:       SHOULD I SEND IN MY STOCK CERTIFICATES NOW? (page __)

A:       No. After the merger is completed, BioShield will send AHT stockholders
         written instructions for exchanging their share certificates. BioShield
         stockholders will keep their existing share certificates.


Q:       AM I ENTITLED TO ASSERT DISSENTERS' OR APPRAISAL RIGHTS? (page __)

A:       BioShield stockholders will not have the opportunity to assert
         dissenters' rights under Georgia law in connection with any of the
         proposals to be voted upon at the annual meeting.

         AHT stockholders will have the opportunity to assert appraisal rights
         relating to the merger. To claim these rights, AHT stockholders must
         comply with the requirements of Delaware law. These requirements
         generally consist of the following:

         -        Before the stockholder vote is taken, you must deliver to AHT
                  written notice of your intention to demand payment for your
                  shares if the merger is effected.

         -        You must continuously hold your AHT shares through the
                  completion of the merger.

         -        You must not vote your shares in favor of the merger either by
                  proxy or in person at the AHT stockholders' meeting.

         -        If you properly notified AHT of your intent to demand
                  appraisal rights, AHT will send you written notice within ten
                  (10) days after the completion of the merger that you have
                  properly asserted your appraisal rights.

         -        Within one hundred twenty (120) days after the completion of
                  the merger, you must file a petition in the Court of Chancery
                  of Delaware demanding that the court determine the fair value
                  of your shares.

         If you do not comply with the requirements outlined above, you will not
be entitled to receive payment for your shares under the appraisal rights
provisions of Delaware law. YOUR APPRAISAL RIGHTS ARE SET OUT IN THEIR ENTIRETY
IN SECTION 262 OF THE GENERAL CORPORATION LAW OF DELAWARE, WHICH IS ATTACHED TO
THIS JOINT PROXY STATEMENT/PROSPECTUS AS APPENDIX Q.

         If holders of more than 900,000 shares of AHT common stock have
delivered notice to AHT of their intention to assert their appraisal rights and
if these holders vote against adoption and approval of the merger and the merger
agreement, BioShield may determine not to complete the merger.


Q:       WHAT ARE THE TAX CONSEQUENCES OF THE MERGER? (page __)

A:       For holders of AHT common stock, we expect that for United States
         federal income tax purposes, your exchange of shares of AHT common
         stock for shares of BioShield common stock generally will not cause you
         to recognize any gain or loss. You will, however, recognize income or
         gain in connection with any cash received instead of fractional shares
         of BioShield common stock. Your holding period for the BioShield common
         stock received in the merger, which determines how any gain or loss
         should be treated for federal income tax purposes upon future sales of
         BioShield common stock, generally will include the holding period for
         the common stock exchanged in the merger.

<PAGE>   18
Q:       WHAT IS THE INTENDED ACCOUNTING TREATMENT OF THE MERGER? (page __)

A:       BioShield intends to account for the merger using the purchase method
         of accounting.


Q:       WILL THE RIGHTS OF AHT STOCKHOLDERS CHANGE AS A RESULT OF THE MERGER?
         (page __)

A:       Yes. Currently, AHT stockholder rights are governed by Delaware law and
         AHT's restated certificate of incorporation and amended and restated
         by-laws, whereas BioShield stockholder rights are governed by Georgia
         law and BioShield's amended and restated articles of incorporation and
         bylaws. After the merger, AHT stockholders will become stockholders of
         BioShield, and therefore their rights will be governed by Georgia law
         and BioShield's amended and restated articles of incorporation and
         bylaws.


Q:       WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED? (page __)

A:       We are working towards completing the merger as quickly as possible. We
         hope to complete the merger on or about September 30, 2000.


Q:       WHERE CAN I FIND MORE INFORMATION ABOUT BIOSHIELD AND AHT? (page __)

A:       You can find more information about BioShield and AHT as described
         under "Where you can find more information" on page __.


Q:       WHOM SHOULD STOCKHOLDERS CALL WITH QUESTIONS AND TO OBTAIN ADDITIONAL
         COPIES OF THE JOINT PROXY STATEMENT/PROSPECTUS? (page __)

A:       BioShield stockholders should call Scott Parliament at (770) 246-2000.

         AHT stockholders should call Arthur Dague at (914) 524-4200.

         In addition to approving the issuance of shares of BioShield's common

         Approval by BioShield stockholders of these other annual meeting

         When AHT stockholders consider the AHT board of directors'

                                       9
<PAGE>   22
STOCK OPTIONS AND OTHER AWARDS (page ____)

         At the effective time of the merger, each outstanding option to
purchase AHT common stock will become an option to acquire, on the same terms
and conditions under the AHT option, the same number of shares of BioShield
common stock as the holder of the AHT option would have been entitled to receive
if that holder fully exercised its option to purchase AHT common stock
immediately prior to the merger. The price per share is equal to the aggregate
exercise price for the AHT common stock that the holder was entitled to purchase
under the option to purchase AHT common stock divided by the number of full
shares of BioShield common stock purchasable under that option.


FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER (page __)

         AHT stockholders' receipt of BioShield common stock in the merger
generally will be tax-free for United States federal income tax purposes, except
for taxes which may result from any receipt of cash instead of fractional shares
of BioShield common stock.


ACCOUNTING TREATMENT (page ___)

         BioShield will account for the merger using the purchase method of
accounting.


OWNERSHIP OF BIOSHIELD AFTER THE MERGER (page __)

         We estimate, based on the current trading price of the BioShield common
stock, that approximately 3.1 million shares of BioShield common stock will be
issued, or issuable upon the exercise of options, warrants or other rights we
expect to be outstanding, to AHT stockholders upon completion of the merger.
These shares will represent approximately 20% of the outstanding shares of
common stock of BioShield after the merger on a fully diluted basis. The shares
of BioShield common stock held by BioShield stockholders before the merger will
represent approximately 80% of the outstanding shares of BioShield common stock
after the merger on a fully diluted basis. BioShield stockholders will continue
to own their existing shares after the merger.

COMPARISON OF RIGHTS OF AHT STOCKHOLDERS AND BIOSHIELD STOCKHOLDERS (page __)

         Currently, AHT stockholder rights are governed by Delaware law and
AHT's certificate of incorporation and by-laws, whereas BioShield stockholder
rights are governed by Georgia law and BioShield's articles of incorporation and
bylaws. After the merger, AHT stockholders will become stockholders of
BioShield, and therefore their rights will be governed by Georgia law and
BioShield's articles of incorporation and bylaws.


APPRAISAL RIGHTS (page __)

         BioShield stockholders are not entitled to dissenters' rights in
connection with the share issuance proposal or the merger.

         AHT stockholders are entitled to appraisal rights in connection with
the merger if you do not vote to adopt and approve the merger agreement and
otherwise comply with Delaware law. If you wish to exercise your appraisal

LISTING OF BIOSHIELD COMMON STOCK (page __).


         As a condition to the merger, BioShield must obtain approval for the
listing of the shares of common stock to be issued by BioShield in the merger so
that these shares will be listed in the Nasdaq SmallCap Market under the ticker
symbol BSTI.


CONDITIONS TO THE MERGER (page ___)

         The completion of the merger depends upon the satisfaction or waiver of
a number of conditions, including the following:

         -        approval of the issuance of shares of BioShield's common stock
                  by BioShield's stockholders and adoption and approval of the
                  merger and the merger agreement by AHT's stockholders;

         -        the absence of any law or court order in effect that would
                  prevent or prohibit consummation of the merger;

         -        authorization of BioShield common stock issuable to AHT
                  stockholders in the merger for listing on the Nasdaq SmallCap
                  Market;

         -        receipt of all regulatory approvals and permits necessary to
                  consummate the transactions contemplated by the merger
                  agreement;

         -        neither BioShield nor AHT being in breach of their respective
                  representations and warranties contained in the merger
                  agreement;

         -        both BioShield and AHT must have performed all of their
                  respective covenants, obligations and agreements in all
                  material respects; and

         -        the holders of record of no more than 900,000 shares of AHT
                  common stock have delivered to AHT written notice of their
                  intention to assert their appraisal rights for their shares of
                  AHT common stock and voted against adoption and approval of
                  the merger agreement and the merger.


NO SOLICITATION OF ACQUISITION PROPOSALS (page __)

         AHT agreed that, prior to the effective time of the merger or the
termination of the merger agreement, it will not initiate or participate in any
discussions or negotiations that may lead to another acquisition proposal. Under
some circumstances, AHT's board of directors may engage in negotiations
concerning an unsolicited acquisition proposal.


TERMINATION (page __)

         We may agree to terminate the merger agreement without completing the
merger. Some of the events that give either of us the right to terminate the
merger agreement include:

         -        the merger is not completed by December 31, 2000;

         -        the AHT stockholders fail to adopt and approve the merger
                  agreement and the merger or the BioShield stockholders fail to
                  approve the issuance of BioShield common stock in connection
                  with the merger;

         -        the boards of directors of both BioShield and AHT agree to
                  terminate the merger agreement;

         -        either AHT or BioShield materially breaches its
                  representations, warranties, covenants or other agreements;


                                       11
<PAGE>   24
         -        the cost of AHT's outstanding litigation, after deductions,
                  will exceed $250,000; or

         -        any statute, injunction or decree preventing or prohibiting
                  the merger becomes final and nonappealable.


TERMINATION FEES (page __)

         AHT must pay BioShield a termination fee of $600,000 if the merger is
terminated under one of the following circumstances:

         -        AHT has received a competing acquisition proposal from another
                  person and has consummated another transaction in connection
                  with any acquisition proposal;

         -        AHT has breached or failed to perform in any material respect
                  any of its covenants or other agreements or if any of AHT's
                  representations and warranties were false when made, if the
                  breach or failure to perform is reasonably likely to have a
                  material adverse effect and has not been or cannot be cured
                  within twenty (20) days after BioShield gives written notice
                  to AHT; or

         -        AHT's board of directors has withdrawn or materially modified
                  its recommendation of the merger or recommended an acquisition
                  proposal from another person.

         In addition to the $600,000 payable by AHT to BioShield, AHT may be
required to pay BioShield up to an additional $240,000 as reimbursement for all
of BioShield's reasonable out-of-pocket expenses incurred in connection with the
merger agreement.

1.       The historical book value per share amounts are computed by dividing
         BioShield's, AHT's and Arrow Magnolia's stockholders' equity,
         respectively, by their actual common shares outstanding as of June 30,
         1999 and March 31, 2000.

2.       The pro forma combined loss per BioShield share assumes the combination
         of BioShield with both AHT and Arrow Magnolia.

3.       The equivalent pro forma AHT combined per share amounts are calculated
         by multiplying the pro forma combined share amounts by the exchange
         ratio of 0.2061 shares of BioShield common stock for each share of AHT.

4.       The equivalent pro forma Arrow Magnolia combined per share amounts are
         calculated by multiplying the pro forma combined share amounts by the
         exchange ratio of 0.0695 shares of BioShield common stock for each
         share of Arrow Magnolia.

5.       The pro forma combined book value per share amounts are computed by
         dividing pro forma stockholders' equity by the pro forma number of
         common shares of BioShield outstanding at March 31, 2000, assuming the
         merger and the acquisition had occurred as of that date.

RISKS RELATING TO THE MERGER

         THE COMBINED COMPANY MAY NOT ACHIEVE THE BENEFITS EXPECTED FROM THE
MERGER. Achieving the benefits of the merger will depend in part on our ability
to realize the anticipated growth opportunities and synergies from combining the
businesses of BioShield's eMD internet healthcare subsidiary and AHT. The
integration of eMD and AHT will be a complex, time-consuming and expensive
process and may disrupt both companies' businesses if not completed in a timely
and efficient manner. The challenges involved in this integration include the
following:

                  -        combining product offerings effectively and quickly;

                  -        successfully promoting and selling the combined
                           products and services of eMD and AHT;

                  -        retaining the existing customers of each company;

                  -        offering products and services of eMD and AHT to each
                           other's customers;

                  -        retaining and integrating management and other key
                           employees of both BioShield and AHT; and

                  -        maintaining adequate focus on our core business
                           during our transition period in order to take
                           advantage of competitive opportunities and respond to
                           competitive challenges.

         It is not certain that eMD and AHT can be successfully integrated in a
timely manner, or at all, or that the anticipated benefits will be realized.
Risks to the successful integration of the companies include:

                  -        the failure to realize anticipated growth in revenue,
                           earnings and cash flow expected from the merger;

                  -        the potential disruption of the combined company's
                           ongoing business and distraction of its management;

                  -        potential unforeseen difficulties in the integration
                           of the technologies and product offerings of eMD and
                           AHT; and

                  -        unanticipated expenses related to the integration of
                           the two companies.

         The combined company may not succeed in addressing these risks or any
other problems encountered in connection with the merger. Further, neither
BioShield nor AHT can assure you that the growth rate of the combined company
will equal the historical growth rates experienced by AHT or eMD.

         WE WILL HAVE TO AMORTIZE GOODWILL THAT WILL INCREASE OUR NET LOSSES.
The combined company's reported financial results will suffer as a result of
purchase accounting treatment of the merger and the impact of amortization of
goodwill and other intangibles relating to the proposed merger. BioShield will
account for the merger as a purchase of AHT using the purchase method of
accounting. As a result, BioShield will record the fair value of the
consideration given for AHT common stock and for options to purchase AHT common
stock assumed by BioShield,


                                       19
<PAGE>   32

plus the amount of direct transaction costs as the cost of acquiring AHT.
BioShield will allocate these costs to the individual AHT assets acquired and
liabilities assumed, including intangible assets. Intangible assets, including
goodwill, will be generally amortized over a three- to seven-year period.

         As described in the unaudited pro forma condensed combined financial
statements included in this joint proxy statement/prospectus, the amount of
purchase cost allocated to goodwill and other intangibles is estimated to be
$18.8 million. If goodwill and other intangible assets were amortized in equal
quarterly amounts following completion of the merger, the accounting charge
attributable to these items would be approximately $0.9 million per quarter or
$3.8 million per fiscal year. As a result, purchase accounting treatment of the
merger will result in a net loss for BioShield in the foreseeable future which
could have a material and adverse effect on the market value of BioShield common
stock following completion of the merger. Additionally, because we will issue
shares of BioShield common stock in connection with the consummation of the
merger, and since AHT has historically not been profitable, the merger may cause
our loss per share to increase.

         THE ISSUANCE OF SHARES OF BIOSHIELD COMMON STOCK IN THE MERGER WILL
RESULT IN IMMEDIATE DILUTION OF THE OUTSTANDING BIOSHIELD COMMON STOCK. Upon
consummation of the merger, approximately 3.1 million shares of BioShield common
stock will be issued or reserved for issuance for holders of AHT common stock
and warrants, options or other rights to purchase or acquire AHT common stock.
The resulting dilution of BioShield's common stock could have a negative impact
on its market price.

         THE MERGER MAY DISRUPT OUR EXISTING BUSINESS, DISTRACT OUR MANAGEMENT
AND DIVERT OUR RESOURCES. The integration of AHT into eMD may take management
time and resources that will have to be diverted from the main business of the
combined company. This diversion of time and resources could have a material
adverse effect on our business, financial condition and results of operations,
which may cause our stock price to decrease.

         COMPLETION OF THE MERGER MAY CAUSE A BREACH UNDER AGREEMENTS TO WHICH
AHT IS A PARTY. The completion of the merger may violate the terms of agreements
to which AHT is a party, or may permit the counterparties to these agreements to
exercise their contractual remedies, such as acceleration of rights or
termination. We will attempt to obtain the consent or waiver of the
counterparties to these agreements, but we may be unsuccessful in our attempts.
In addition, various persons with whom AHT historically has had business
relationships may attempt to be released from, or fail to perform their
obligations under, their contracts as a result of the merger, even if the terms
of their contracts with AHT do not allow a release. If we are not able to obtain
consents or waivers from the counterparties to AHT's contracts, or if a
sufficient number of AHT's business partners refuse to perform their
obligations, our business, financial condition and results of operations may be
adversely affected.

         BECAUSE THE COMBINED COMPANY WILL BE A NEWLY INTEGRATED ENTITY, THE
HISTORICAL AND PRO FORMA FINANCIAL STATEMENTS IN THIS PROXY STATEMENT/PROSPECTUS
MAY BE OF LIMITED VALUE IN EVALUATING OUR FUTURE PERFORMANCE. The combination of
eMD and AHT will result in a new enterprise that has not operated before as a
single integrated unit. As a result, the financial information in this joint
proxy statement/prospectus concerning the individual operations of AHT and
BioShield and the pro forma financial information concerning the combined entity
may be of limited value in evaluating our financial and operating prospects in
the future.

RISKS RELATING TO BIOSHIELD AND ITS BUSINESS

         WE MAY NOT BE ABLE TO FURTHER COMMERCIALIZE OUR PRODUCTS EVEN AFTER
RECEIPT OF REGULATORY APPROVALS TO DO SO. We were organized in June 1995 and
were a development stage company until regulatory approval was received for our
core product in February, 2000. BioShield's long-term viability, profitability
and growth will depend upon the successful commercialization of our core product
resulting from our research and product development activities. We may encounter
significant challenges in shifting from the development to commercialization of
our new products. We may not be able to sell significant quantities of any
product outside of retail distribution channels until the time we receive
expanded regulatory approval to commercially market our products in additional
industrial and medical markets. Any regulatory approvals we receive may be
limited in scope. Additionally, many of our products will require laboratory and
clinical testing and investment prior to obtaining regulatory approvals and
prior to full commercialization. We cannot assure you that these approvals will
be obtained. We have not filed any applications or registrations with the U.S.
Food and Drug Administration, or FDA, and none are anticipated to be filed in
the near future. In addition, with respect to the FDA, adverse or inconclusive
results in clinical trials could significantly delay or ultimately preclude any
regulatory approvals. Even


                                       20
<PAGE>   33

if we obtain regulatory approvals, there can be no assurance that any product
approval will lead to the successful commercialization of our products.

         WE HAVE A LIMITED OPERATING HISTORY, HAVE NEVER BEEN PROFITABLE AND MAY
NEVER DEVELOP A COMMERCIALLY SUCCESSFUL PRODUCT. We have limited relevant
operating history upon which you can evaluate our prospects. Our prospects must
be considered in light of the risks, expenses and difficulties frequently
encountered in establishing a new business in the evolving, heavily regulated
healthcare, drug, and medical device industry. This industry is characterized by
an increasing number of market entrants, intense competition and a high failure
rate. Additionally, we have just begun to incorporate our technologies into
commercial products.

         WE HAVE GENERATED LIMITED REVENUE TO DATE, HAVE A HISTORY OF
SIGNIFICANT LOSSES AND EXPECT CONTINUED LOSSES. We have generated only limited
revenue from product sales and consulting to date. Through March 31, 2000,
although we have recorded contract revenue, we have generated revenue from
product sales of only approximately $2.3 million since 1995. In addition, we
have incurred significant losses, including losses of $356,316, $514,459,
$1,471,929, and $3,289,616 for the thirteen months ended June 30, 1996 and for
the fiscal years ended June 30, 1997, 1998 and 1999, respectively. For the
thirteen months ended June 30, 1996, and for the fiscal years ended June 30,
1997, 1998 and 1999, we recorded product sale revenue of $0, $775,315, $462,471
and $305,336. Our net sales during the nine months ended March 31, 1999 and 2000
were $286,182 and $737,182, respectively, while net losses increased from
$1,536,020 to $13,640,267 during the same period as we used the proceeds of our
initial public offering and other financings to increase marketing and
development efforts. Because we will continue to have high research and
development and general and administrative expenses for the foreseeable future
without matching revenues, we anticipate continued net losses until the time, if
ever, as we are able to generate sufficient revenues to support our operations.

         OUR LOSSES WILL PROBABLY CONTINUE FOR AN INDEFINITE PERIOD. We believe
that our ability to generate sufficient revenues, aside from the retail market,
may depend on our success in obtaining regulatory registrations for the
commercial sale of additional products. We cannot assure you that we will
receive approval to sell additional products, or that we will derive revenue
from the commercialization of our products. Additionally, we can not assure you
that we will ever be profitable.

         OUR CONTINUED EXISTENCE AS A GOING CONCERN IS DEPENDENT UPON THE
SUCCESS OF OUR FUTURE OPERATIONS AND OUR ABILITY TO OBTAIN ADDITIONAL FINANCING.
We currently have and will continue to have significant capital requirements to
fund our operations. To fund our capital requirements to date, we have been
dependent primarily on:

                  -        sales revenue generated primarily from the sale of
                           our products;

                  -        the net cash proceeds of private placements of
                           BioShield and eMD securities; and

                  -        the proceeds of our initial public offering.

         We anticipate, based on our currently proposed plans and assumptions
relating to our operations, that current working capital and projected revenues,
together with the proceeds of private placements of our convertible preferred
stock effected in January and June, 2000 and the availability of approximately
$58 million in the form of two private equity facilities, will be sufficient to
satisfy our estimated cash requirements through the end of 2001. We expect to
incur substantial costs to complete the primary development of our products for
the medical and industrial markets. Therefore, unless we generate significant
revenues during this period, we may need additional financing to fully fund this
development. We have no other current sources of additional financing and it is
not anticipated that any of the officers, directors or stockholders of BioShield
will provide any portion of our future financing requirements. We cannot assure
you that additional financing will be available on commercially reasonable
terms, or at all. Any inability to obtain additional financing when needed could
require us to significantly curtail or possibly cease operations. We may also
need to raise additional funds to respond to business contingencies, which may
include the need to:

                  -        fund more rapid expansion;

                  -        fund additional marketing expenditures;


                                       21
<PAGE>   34

                  -        develop new or enhance existing editorial content,
                           features or services;

                  -        enhance our operating infrastructure;

                  -        respond to competitive pressures; or

                  -        acquire complementary businesses or necessary
                           technologies.

         If additional funds are raised through the issuance of equity or
convertible debt securities, the percentage ownership of our stockholders will
be reduced, and these newly-issued securities may have rights, preferences or
privileges senior to those of existing stockholders, including those acquiring
shares in connection with the merger. We cannot assure you that additional
financing will be available on terms favorable to us, or at all.

         EMD WILL DEPLETE OUR CAPITAL MORE QUICKLY THAN OUR TRADITIONAL
BUSINESS. We may require substantial capital in excess of what we now have
available in order to complete the development and implement the operation of
eMD.

         OUR BUSINESS MAY NOT GROW IF OUR PRODUCTS DO NOT RECEIVE ADDITIONAL
REGULATORY APPROVAL AND WE COULD BEAR SUBSTANTIAL REGULATORY COSTS. The
development, manufacture, testing and marketing of all of our products are
subject to extensive regulation by numerous authorities in the United States and
other countries. In the United States, before new antimicrobial products for
humans are permitted to be marketed commercially, they must undergo extensive
preclinical and clinical testing. Delays in obtaining additional regulatory
approvals may adversely affect the development, testing or marketing of our
products and our ability to generate revenues from the sale or licensing of our
products. We cannot assure you that we will obtain additional regulatory
approvals in the United States or any other country to sell our products for
these purposes.

         WE ARE AT A COMPETITIVE DISADVANTAGE TO LARGE, WELL-ESTABLISHED
COMPANIES. The markets for our products are competitive. Competition from
companies that produce antimicrobial products for commercial use is intense and
we expect the competition to increase. We cannot assure you that other companies
will not develop new products that are directly competitive with our products.
We are aware of several other companies that currently manufacture products that
compete directly with our products. Some of these companies have
well-established reputations for success in the development, sale and service of
conventional antimicrobial products and have substantially greater financial,
technical, personnel and other resources than we do. We cannot assure you that
we will be able to compete successfully, that competitors will not develop
technologies or products that render our products obsolete or less marketable or
that we will be able to successfully enhance our existing products or develop or
acquire new products.

         OUR PRODUCTS MAY BECOME OBSOLETE. The antimicrobial industry is subject
to rapid and significant technological change, and our ability to compete is
dependent in large part on continued improvements to our products and
technologies. In order to remain competitive, we must effectively utilize and
expand our research and development capabilities, and, once developed, quickly
convert new technology into products and processes that we can sell to the
public. Our competitors may succeed in developing technologies, products and
processes that render our processes and products obsolete. Some entities have
filed applications for or have been issued patents and may obtain additional
patents and proprietary rights relating to products or processes that compete
with or are related to our products. The scope and viability of these patents,
the extent to which we may be required to obtain licenses under these patents or
under other proprietary rights and the cost and availability of licenses are
unknown, but these factors may limit our ability to market our products.

         OUR BUSINESS POTENTIALLY EXPOSES US TO PRODUCT LIABILITIES THAT ARE
INHERENT IN THE TESTING, MANUFACTURING, MARKETING AND SALE OF THERAPEUTIC
PRODUCTS. While we will take precautions we deem appropriate, we cannot assure
you that we will be able to avoid significant exposure to product liability
lawsuits. We have obtained general liability insurance in the amount of
$1,000,000, which includes aggregate product coverage of $1,000,000. We also
have an umbrella liability policy with an aggregate limit of $5,000,000. We
cannot assure you that we will be able to obtain product liability coverage in
the future on acceptable terms or that any insurance policy will provide
adequate protection against potential claims. A successful claim brought against
us in excess of any insurance coverage could have a material adverse effect on
our business, financial condition and results of operations.


                                       22
<PAGE>   35

         THE MARKET MAY NOT ACCEPT OUR PRODUCTS. To date, we have generated
limited revenue from sales of our products. We have not yet commenced
significant marketing activities, we have limited marketing experience and
limited resources to independently undertake extensive marketing activities. The
demand and market acceptance for our newly introduced products is highly
uncertain. Achieving market acceptance for our products will require substantial
marketing efforts and expenditure of significant funds to inform customers of
the distinctive characteristics and benefits of using our products. We cannot
assure you that our marketing efforts will result in successful
commercialization or market acceptance of our products.

         WE ARE VERY DEPENDENT ON KEY PERSONNEL. Our success will be largely
dependent on the abilities and continued personal efforts of Timothy C. Moses,
one of BioShield's founders and chairman of the board of directors, president,
and chief executive officer of BioShield. We employ Timothy Moses under an
employment agreement which expires on January 1, 2003. The loss of the services
of Timothy Moses would have a material adverse effect on our business, financial
condition and results of operations. We are also a beneficiary of a key man life
insurance policy in the amount of $1,000,000 on Timothy Moses. We do not
currently own policies covering any other officer or employee.

         THERE ARE SUBSTANTIAL STOCKHOLDERS OF BIOSHIELD. Timothy Moses, one of
BioShield's founders and chairman of the board of directors, president, and
chief executive officer of BioShield, beneficially owns approximately 20% of the
outstanding shares of BioShield common stock. Jacques Elfersy, one of
BioShield's founders and a former executive officer of BioShield, owns
approximately 22% of the outstanding shares of BioShield common stock. As a
result of their significant ownership, Timothy Moses and Jacques Elfersy may be
able to exert significant influence over the outcome of stockholder votes,
including votes concerning the election of directors, the adoption of amendments
to BioShield's articles of incorporation or bylaws and the approval of mergers
and other significant corporate transactions, including a sale of substantially
all of our assets. This influence could also have the effect of delaying,
deferring or preventing a change in control of BioShield that BioShield's
stockholders would favor.

         WE CANNOT ASSURE YOU THAT THERE WILL BE A CONTINUED PUBLIC MARKET FOR
BIOSHIELD COMMON STOCK. The market prices for securities of biotechnology
companies, including BioShield, have been volatile. Many factors may have a
significant effect on the market price or liquidity of our common stock,
including:

                  -        announcements of technological innovations or new
                           products by us or our competitors;

                  -        developments concerning proprietary rights including
                           patents and litigation matters;

                  -        publicity regarding actual or potential clinical
                           testing relating to products under development by us
                           or others;

                  -        regulatory developments in both the United States and
                           foreign countries;

                  -        public concern regarding the safety of biotechnology
                           products;

                  -        economic and other external factors; and

                  -        period-to-period fluctuations in financial results.

         Additionally, in recent years, the stock market has experienced a high
level of price and volume volatility and market prices for the stock of many
companies, including BioShield.

         A SIGNIFICANT NUMBER OF SHARES OF BIOSHIELD COMMON STOCK MAY BE RESOLD
IN THE PUBLIC MARKET. In September 1999, over 4.5 million shares of BioShield
common stock that were restricted securities became eligible for resale pursuant
to Rule 144 under the Securities Act after the expiration of a lock-up
agreement. Any sales of significant amounts of these shares in the public
markets could adversely affect the market price of BioShield common stock.

         A SUBSTANTIAL NUMBER OF SHARES OF BIOSHIELD COMMON STOCK MAY BE ISSUED
AT A DISCOUNT TO THE MARKET PRICE FOR THOSE SHARES. We have filed a registration
statement covering up to 1,000,000 shares of BioShield


                                       23
<PAGE>   36

common stock which may be issued in connection with the exchange of shares of
eMD common stock and related warrants. The exchange would be at a discount to
the then-current market value of BioShield common stock. We have also issued a
series of convertible preferred stock, which is convertible into BioShield
common stock at a discount to the then-current market value. For information
about BioShield's capital stock, see "Description of capital stock" on page [ ]
of this joint proxy statement/prospectus. The effect of these exchanges and
conversions may have a negative impact on the trading price of BioShield's
common stock, may enable these investors to acquire a substantial ownership
position in BioShield and may significantly dilute the interest of existing
BioShield stockholders.

         A SUBSTANTIAL NUMBER OF SHARES OF BIOSHIELD COMMON STOCK HAVE BEEN
RESERVED FOR ISSUANCE UPON THE CONVERSION OF OUTSTANDING OPTIONS. We have
reserved up to 2 million shares of BioShield common stock for issuance to our
key employees, officers, directors and consultants pursuant to our stock
incentive plan and 1 million shares of BioShield common stock for issuance to
directors pursuant to our directors' stock option plan. As of July 15, 2000,
921,000 options have been granted under the stock incentive plan, of which
480,000 are immediately exercisable, and 595,000 options have been granted under
the directors' plan, all of which are immediately exercisable. The existence of
these options and any other options or warrants may prove to be a hindrance to
future equity financing by BioShield. In addition, these options may result in
sales of common stock to officers and directors of BioShield at prices well
below the market price at the time of option exercise.

         OUR DIRECTORS ARE AUTHORIZED TO ISSUE A SERIES OF BLANK CHECK PREFERRED
STOCK, WHICH, IF ISSUED, MAY HARM THE RIGHTS OF HOLDERS OF SHARES OF BIOSHIELD
COMMON STOCK. BioShield's articles of incorporation authorize the issuance of
blank check preferred stock with designations, rights and preferences that
BioShield's board of directors may determine. Accordingly, our board of
directors is empowered, without stockholder approval, to issue additional
preferred stock with dividend, liquidation, conversion, voting or other rights
which could adversely affect the voting power or other rights of the holders of
shares of BioShield common stock. The issuance of a series of preferred stock
could be used to discourage, delay or prevent a change in control of BioShield,
to the harm of the stockholders. Although management has no present intention of
issuing any shares of its authorized preferred stock, BioShield may do so in the
future.

         OUR ARTICLES OF INCORPORATION AND BYLAWS CONTAIN ANTI-TAKEOVER
PROVISIONS THAT MAY DISCOURAGE OR PREVENT POTENTIAL ACQUIRORS FROM ACQUIRING
BIOSHIELD. Our articles of incorporation and bylaws contain numerous
anti-takeover provisions that will encourage any potential acquiror of BioShield
to deal directly with BioShield's board of directors. These provisions include:

                  -        a classified board of directors with directors
                           serving staggered three-year terms;

                  -        a prohibition against majority stockholders taking
                           actions by written consent;

                  -        restrictions on the power of stockholders to call
                           special meetings of the stockholders;

                  -        requirements that the board of directors must have
                           advance notice of any business to be introduced at a
                           stockholders' meeting and nominees for election to
                           the board of directors;

                  -        adoption of provisions of Georgia law regarding
                           business combinations;

                  -        authorization for BioShield's board of directors to
                           consider the effects of any proposed acquisition on
                           employees, customers, suppliers and the community;

                  -        provisions requiring that directors can only be
                           removed for cause and by a greater than majority vote
                           of stockholders; and

                  -        provisions requiring that unless BioShield's board of
                           directors has approved an acquisition, a greater than
                           majority vote of the stockholders is required in
                           order to approve the acquisition.


                                       24
<PAGE>   37

         These anti-takeover provisions could allow BioShield's board of
directors to impede or prevent an acquisition of BioShield even if stockholders
support the acquisition. These provisions could also serve to entrench incumbent
management.

         BIOSHIELD HAS NEVER PAID DIVIDENDS TO ITS STOCKHOLDERS AND DOES NOT
FORESEE PAYING DIVIDENDS IN THE FORESEEABLE FUTURE. To date, BioShield has never
paid any cash dividends on its common stock and it does not expect to declare or
pay dividends on its common stock in the foreseeable future. In addition, future
agreements or credit facilities may restrict dividend payments.

         WE MAY FAIL TO RETAIN OUR LISTING ON THE NASDAQ SMALLCAP MARKET. While
BioShield's common stock currently meets the listing requirements for inclusion
in the Nasdaq SmallCap Market, we cannot assure you that we will continue to
meet the listing requirements. If BioShield is unable to satisfy the Nasdaq
SmallCap Market's requirements for continued listing, our common stock may be
delisted. If our common stock is delisted, our common stock would then be traded
only in the over-the-counter market in the so-called "pink sheets" or the NASD's
OTC Bulletin Board. As a result, the liquidity of BioShield's common stock could
be impaired, not only in the number of shares of BioShield common stock which
could be bought and sold, but also through delays in the timing of transactions,
reduced numbers of security analysts' and the news media's coverage of BioShield
and lower prices for our securities than might otherwise be attained.

         In addition, if our common stock is delisted from trading on the Nasdaq
SmallCap Market and the trading price of the common stock falls below $5.00 per
share, trading in the common stock would be subject to the requirements of
certain rules promulgated under the Exchange Act. These rules would require
broker-dealers to provide additional disclosure in connection with any sales of
BioShield common stock. These rules would also require broker-dealers to sell
these securities only to established customers, accredited investors, as defined
in the Securities Act, or other investors who give prior written consent before
purchasing or selling their shares of BioShield common stock. The additional
burdens imposed on broker-dealers by these requirements may discourage them from
effecting transactions in BioShield common stock, which could severely limit the
liquidity of the BioShield common stock.

         WE MAY NOT BE ABLE TO OBTAIN CASH THAT WE EXPECT TO HAVE ACCESS TO
THROUGH OUR PRIVATE EQUITY CREDIT AGREEMENTS. Our business plans rely in part
upon the receipt of part of the remaining $58 million in financing provided for
under our private equity credit agreements. However, there are circumstances
under which we may not receive all or any part of that financing, including:

                  -        If we do not effect or maintain the effectiveness of
                           the required registration statements with the SEC, or
                           any of the other conditions contained in the private
                           equity credit agreements are not satisfied or waived,
                           we will not be able to cause the investor to purchase
                           the shares under the private equity credit
                           agreements;

                  -        We currently cannot issue more than 19.99% of the
                           shares outstanding immediately prior to the execution
                           of either of the private equity credit agreements,
                           unless we secure stockholder approval of the issuance
                           of the shares. Accordingly, depending on the market
                           price of our shares, in the absence of stockholder
                           approval, we may not receive all the anticipated
                           proceeds of the private equity credit agreements; and

                  -        The obligations of the private investor under the
                           private equity credit agreements are not secured or
                           guaranteed, and if the investor does not have
                           available funds or otherwise refuse to honor its
                           obligations to us, we may not be able to force it to
                           do so.

         Further, if we are successful in selling shares under the private
equity credit agreements, those sales will likely be at a discount to the
current market price, and the existing stockholders of BioShield may experience
significant dilution. As the market price for our common stock decreases, the
number of shares which may be sold to the investor will increase. If we require
the investor to purchase our shares at a time when our stock price is depressed,
our existing stockholders' interest in our company will be significantly
reduced.

         ANY FUTURE ACQUISITIONS WE MAKE OF COMPANIES OR TECHNOLOGIES MAY RESULT
IN DISRUPTIONS TO OUR BUSINESS OR THE DISTRACTION OF OUR MANAGEMENT. We may
acquire or make investments in complementary businesses, technologies, services
or products if appropriate opportunities arise. From time to time we engage in


                                       25
<PAGE>   38

discussions and negotiations with companies regarding our acquiring or investing
in those companies' businesses, products, services or technologies, and we
regularly engage in these discussions and negotiations in the ordinary course of
our business. Some of those discussions contemplate the other party making an
investment in BioShield or eMD. However, we cannot give you any assurance that
investments will be made. We cannot assure you that we will be able to identify
future suitable acquisition or investment candidates, or if we do identify
suitable candidates, that we will be able to make any acquisitions or
investments on commercially acceptable terms or at all. If we acquire or invest
in another company, we could have difficulty in assimilating that company's
personnel, operations, technology and software. In addition, the key personnel
of the acquired company may decide not to work for us. If we make other types of
acquisitions, we could have difficulty in integrating the acquired products,
services or technologies into our operations. These difficulties could disrupt
our ongoing business, distract our management and employees, increase our
expenses and adversely affect our results of operations. Furthermore, we may
incur indebtedness or issue equity securities to pay for any future
acquisitions. The issuance of equity securities would be dilutive to our
existing stockholders. As of the date of this prospectus, other than the
proposed AHT merger and the proposed acquisition of up to 85% of the outstanding
stock of Arrow Magnolia International, Inc., we have no agreement to enter into
any material investment or acquisition transaction.

         OUR BUSINESS MAY FACE ADDITIONAL RISKS AND UNCERTAINTIES NOT PRESENTLY
KNOWN TO US WHICH COULD CAUSE OUR BUSINESS TO SUFFER. In addition to the risks
specifically identified in this Risk factors section or elsewhere in this
prospectus, we may face additional risks and uncertainties not presently known
to us or that we currently deem immaterial which ultimately impair our business,
results of operations and financial condition.



RISKS PARTICULAR TO EMD

         EMD WILL DEPLETE OUR CAPITAL MORE QUICKLY THAN OUR TRADITIONAL
BUSINESS. We may require substantial capital in excess of what we now have
available in order to complete the development and implement the operation of
eMD.

         CONSUMERS AND THE HEALTHCARE INDUSTRY MUST ACCEPT THE INTERNET AS A
SOURCE OF HEALTHCARE CONTENT AND SERVICES FOR OUR BUSINESS MODEL TO BE
SUCCESSFUL. To be successful, we must attract to our network a significant
number of consumers as well as other participants in the healthcare industry. To
date, consumers have generally looked to healthcare professionals as their
principal source for health and wellness information. Our business model assumes
that both physicians and consumers will use healthcare information and purchase
goods and services, including prescriptions drugs available on our network, that
consumers will access important healthcare needs through electronic commerce
using our website, and that local healthcare organizations will affiliate with
us. This business model is not yet proven, and if we are unable to successfully
implement our business model, our business will be materially adversely
affected.

         THE INTERNET INDUSTRY IS HIGHLY COMPETITIVE AND CHANGING RAPIDLY, AND
WE MAY NOT HAVE THE RESOURCES TO COMPETE ADEQUATELY. The number of internet
websites offering users healthcare content, products and services is vast and
increasing at a rapid rate. These companies compete with us for users,
e-commerce transactions and other sources of on-line revenue. In addition,
traditional media and healthcare providers compete for consumers' attention both
through traditional means as well as through new internet initiatives. We
believe that competition for healthcare consumers will continue to increase as
the internet develops as a communication and commercial medium.

         We compete directly for users, e-commerce merchants, syndication
partners and other affiliates with numerous internet and non-internet
businesses, including:

                  -        health-related on-line services or websites targeted
                           at consumers, such as accesshealth.com, ahn.com,
                           betterhealth.com, drkoop.com, drweil.com,
                           healthcentral.com, healthgate.com, intelihealth.com,
                           mayohealth.org; mediconsult.com, onhealth.com,
                           thriveonline.com and webmd.com;

                  -        on-line and internet portal companies, such as
                           America Online, Inc.; Microsoft Network; Yahoo! Inc.;
                           Excite, Inc.; Lycos Corporation and Infoseek
                           Corporation;


                                       26
<PAGE>   39

                  -        electronic merchants and conventional retailers that
                           provide healthcare goods and services competitive to
                           those available from links on our website;

                  -        hospitals, HMOs, managed care organizations,
                           insurance companies and other healthcare providers
                           and payors which offer healthcare information through
                           the internet; and

                  -        other consumer affinity groups, such as the American
                           Association of Retired Persons, SeniorNet and
                           ThirdAge Media, Inc. which offer healthcare-related
                           content to specific demographic groups.

         Many of these potential competitors are likely to enjoy substantial
competitive advantages compared to eMD, including:

                  -        the ability to offer a wider array of on-line
                           products and services;

                  -        larger production and technical staffs;

                  -        greater name recognition and larger marketing budgets
                           and resources;

                  -        larger customer and user bases; and

                  -        substantially greater financial, technical and other
                           resources.

         To be competitive, we must respond promptly and effectively to the
challenges of technological change, evolving standards and our competitors'
innovations by continuing to enhance our products and services, as well as our
sales and marketing channels. Increased competition could result in a loss of
our market share or a reduction in our prices or margins. Competition is likely
to increase significantly as new companies enter the market and current
competitors expand their services.

         OUR BUSINESS IS SUBJECT TO GOVERNMENT REGULATION RELATING TO THE
INTERNET WHICH COULD IMPAIR OUR OPERATIONS. Because of the increasing use of the
internet as a communication and commercial medium, the government has adopted
and may adopt additional laws and regulations with respect to the internet
covering areas such as user privacy, pricing, content, taxation, copyright
protection, distribution and characteristics and quality of production and
services. Since we operate a healthcare network over the internet, our business
is subject to government regulation specifically relating to medical devices,
the practice of medicine and pharmacology, healthcare regulation, insurance and
other matters unique to the healthcare area. Laws and regulations have been or
may be adopted with respect to the provision of healthcare-related products and
services on-line, covering areas such as:

                  -        the regulation of medical devices;

                  -        the practice of medicine and pharmacology and the
                           sale of controlled products such as pharmaceuticals
                           on-line; and

                  -        the regulation of government and third-party cost
                           reimbursement.

         WE MAY BECOME SUBJECT TO REGULATION BY THE FDA. Some computer
applications and software are considered medical devices and are subject to
regulation by the Food and Drug Administration. We do not believe that our
current applications or services will be regulated by the FDA; however, our
applications and services may become subject to FDA regulation. Additionally, we
may expand our application and service offerings into areas that subject us to
FDA regulation. We have no experience in complying with FDA regulations. We
believe that complying with FDA regulations would be time consuming, burdensome
and expensive and could delay or prevent our introduction of new applications or
services.

         WE MAY BECOME SUBJECT TO LICENSING REQUIREMENTS UNDER STATE LAW. The
practice of medicine and pharmacology requires licensing under applicable state
law. We have endeavored to structure our website and affiliate relationships to
avoid violation of state licensing requirements, but a state regulatory
authority may at some


                                       27
<PAGE>   40

point allege that some portion of our business violates these statutes. Any
allegation of this type could result in a material adverse effect on our
business. In addition, any liability based on a determination that we engaged in
the practice of medicine without a license may be excluded from coverage under
the terms of our current general liability insurance policy.

         FEDERAL AND STATE LAWS PROHIBIT RECEIPT OF REFERRAL FEES FOR SOME KINDS
OF PHARMACY PRODUCTS. We earn a service fee when users on our website purchase
prescription pharmacy products from certain of our e-commerce partners. The fee
is not based on the value of the sales transaction. Federal and state
anti-kickback laws prohibit granting or receiving referral fees in connection
with sales of pharmacy products that are reimbursable under federal medicare and
medicaid programs and other reimbursement programs. Although there is
uncertainty regarding the applicability of these regulations to our e-commerce
revenue strategy, we believe that the service fees we receive from our
e-commerce partners are for the primary purpose of marketing and do not
constitute payments that would violate federal or state anti-kickback laws.
However, if our program were deemed to be inconsistent with federal or state
law, we could face criminal or civil penalties. Further, we would be required
either not to accept any transactions which are subject to reimbursement under
federal or state healthcare programs or to restructure our compensation to
comply with any applicable anti-kickback laws or regulations. In addition,
similar laws in several states apply not only to government reimbursement but
also to reimbursement by private insurers. If our activities were deemed to
violate any of these laws or regulations, it could cause a material adverse
affect on our business, results of operations and financial condition.

         THERE IS NO ESTABLISHED MARKET FOR THE CONSUMER HEALTHCARE E-COMMERCE
TRANSACTIONS WE FACILITATE. We plan to develop relationships with retailers,
manufacturers and other providers to offer healthcare products and services
through direct links from our website to their website. This strategy involves
numerous risks and uncertainties. There is no established business model for the
sale of healthcare products or services over the internet. Accordingly, we have
limited experience in the sale of products and services on-line and the
development of relationships with retailers, manufacturers or other providers of
these products and services, and we cannot predict the rate at which consumers
will elect to engage in this form of commerce or the compensation that we will
receive for enabling these transactions. Consumers may sue us if any of the
products or services that are sold through our website are defective, fail to
perform properly or injure the user, even if these goods and services are
provided by unrelated third parties. Some of our agreements with manufacturers,
retailers and other providers contain provisions intended to limit our exposure
to liability claims. These limitations may not however prevent all potential
claims, and our insurance may not adequately protect us from these types of
claims. Liability claims could require us to spend significant time and money in
litigation or to pay significant damages. As a result, any claims of this
nature, whether or not successful, could seriously damage our reputation and our
business.

         INTERNET CAPACITY CONSTRAINTS MAY IMPAIR THE ABILITY OF CONSUMERS TO
ACCESS OUR WEBSITE, WHICH COULD HINDER OUR ABILITY TO GENERATE TRANSACTION AND
E-COMMERCE REVENUE. Our success will depend, in large part, upon a robust
communications industry and infrastructure for providing internet access and
carrying internet traffic. The internet may not prove to be a viable commercial
medium because of:

                  -        inadequate development of the necessary
                           infrastructure such as a reliable network backbone;

                  -        lack of timely development of complementary products
                           such as high speed modems;

                  -        delays in the development or adoption of new
                           standards and protocols required to handle increased
                           levels of internet activity; or

                  -        increased government regulation.

         If the internet continues to experience significant growth in the
number of users and the level of use, then the internet infrastructure may not
be able to continue to support the demands placed on it.

         OUR BUSINESS IS DEPENDENT ON THE CONTINUOUS, RELIABLE AND SECURE
OPERATION OF OUR WEBSITE AND RELATED TOOLS AND FUNCTIONS WE PROVIDE. We rely on
the internet and, accordingly, depend upon the continuous, reliable and secure
operation of internet servers and related hardware and software. Recently,
several large internet commerce companies have suffered highly publicized system
failures which resulted in adverse reactions to their stock prices, significant
negative publicity and, in certain instances, litigation. We have also suffered
service outages


                                       28
<PAGE>   41

from time to time, although to date none of these interruptions has materially
adversely effected our business operations or financial condition. To the extent
that our service is interrupted, our users will be inconvenienced, our
commercial customers will suffer from a loss in transaction delivery and our
reputation may be diminished. Some of these outcomes could directly result in a
reduction in our stock price, significant negative publicity and litigation.

         Our computer and communications hardware are protected through physical
and software safeguards. However, they are still vulnerable to fire, storm,
flood, power loss, telecommunications failures, physical or software break-ins
and similar events. We do not have full redundancy for all of our computer and
telecommunications facilities and do not maintain a back-up data facility. Our
business interruption insurance may be inadequate to protect us in the event of
a catastrophe. We also depend upon third parties to provide potential users with
web browsers and internet and on-line services necessary for access to our
website. In the past, our users have occasionally experienced difficulties with
internet and other on-line services due to system failures, including failures
unrelated to our systems. Any sustained disruption in internet access provided
by third parties could adversely impact our business. We retain confidential
customer information in our database. Therefore, it is critical that our
facilities and infrastructure remain secure and are perceived by consumers to be
secure. Despite the implementation of security measures, our infrastructure may
be vulnerable to physical break-ins, computer viruses, programming errors or
similar disruptive problems. A material security breach could damage our
reputation or result in liability to us.

         EMD IS STILL IN THE INITIAL STAGES OF ITS OPERATIONS AND HAS A LIMITED
OPERATING HISTORY. eMD is still in the initial stages of its internet and
related operations and is in the process of further developing its site and
related business. We launched the consumer and physician portions of eMD's
website in January 2000. Accordingly, eMD has an extremely limited operating
history. You should consider the risks, uncertainties, expenses and difficulties
frequently encountered by companies in their early stages of development,
particularly companies in new and rapidly evolving markets, including the
internet market. These risks and difficulties include our ability to:

                  -        attract a larger audience of users to our eMD website
                           than our competitors are able to attract;

                  -        increase awareness of our brand;

                  -        strengthen user loyalty and increase the number of
                           registered users;

                  -        offer compelling on-line content, services and
                           e-commerce opportunities;

                  -        maintain our current, and develop new, affiliate
                           relationships;

                  -        respond effectively to the offerings of competitive
                           providers of healthcare information on the internet;

                  -        continue to develop and upgrade our technology;

                  -        attract, retain and motivate qualified personnel; and

                  -        increase the number of prescriptions and laboratory
                           transactions processed through our website.

         We also depend on the growing use of the internet for commerce and
communication, and on general economic conditions. We cannot assure you that our
business strategy will be successful or that we will successfully address these
risks or difficulties. If we fail to address adequately any of these risks or
difficulties, our business will likely suffer.

         OUR BUSINESS IS CHANGING RAPIDLY, WHICH COULD CAUSE OUR QUARTERLY
OPERATING RESULTS TO VARY AND OUR STOCK PRICE TO FLUCTUATE. Our revenue and
operating results may vary significantly from quarter to quarter due to a number
of factors, not all of which are in our control. If we have a shortfall in
revenue, or if our expenses precede increased revenues, then our business would
be materially adversely affected. This would likely affect the market


                                       29
<PAGE>   42

price of our common stock in a manner which may be unrelated to our long-term
operating performance. Important factors which could cause eMD's results to
fluctuate materially include:

                  -        our ability to attract and retain users;

                  -        traffic levels on our internet site;

                  -        our ability to attract and retain customers and
                           maintain customer satisfaction for our existing and
                           future e-commerce offerings;

                  -        new internet sites, services or products introduced
                           by us or our competitors;

                  -        the level of internet and other on-line services
                           usage;

                  -        our ability to upgrade and develop our systems and
                           infrastructure and attract new personnel in a timely
                           and effective manner;

                  -        our ability to successfully integrate operations and
                           technologies from any acquisitions, joint ventures or
                           other business combinations or investments; and

                  -        technical difficulties or system downtime affecting
                           the operation of our website.

         eMD revenue for the foreseeable future will remain dependent on user
traffic levels and e-commerce activity on eMD and the level of physician
participation. This future revenue is difficult to forecast. In addition, we
plan to increase our sales and marketing operations, expand and develop content
and upgrade and enhance our technology and infrastructure development in order
to support our growth. Many of the expenses associated with these activities --
for example, personnel costs and technology and infrastructure costs -- are
relatively fixed in the short-term. We may be unable to adjust spending quickly
enough to offset any unexpected revenue shortfall, in which case our results of
operations would suffer. However, we cannot assure you that we will ever achieve
profitable operations for eMD.

         In addition, market prices of emerging internet companies have been
highly volatile, and the market for our stock may exhibit volatility as well.

         WE MUST ESTABLISH, MAINTAIN AND STRENGTHEN OUR BRAND IN ORDER TO
ATTRACT USERS TO OUR NETWORK AND GENERATE SPONSORSHIP AND E-COMMERCE REVENUE. In
order to expand our audience of users and increase our on-line traffic, we must
establish, maintain and strengthen our brand. For us to be successful in
establishing our brand, healthcare consumers must perceive us as a trusted
source of healthcare information, products and services, and advertisers,
merchants and manufacturers must perceive us as an effective marketing and sales
channel for their products and services. We expect that we will need to
substantially increase our marketing budget in our efforts to establish brand
recognition and brand loyalty. Our business could be materially adversely
affected if our marketing efforts are not productive or if we cannot strengthen
our brand.

         WE HAVE COMMITTED AND WILL REQUIRE SIGNIFICANT FINANCIAL AND MARKETING
RESOURCES TO EXPAND OUR NETWORK. If we are unable to earn revenues in excess of
these commitments, our business will suffer. In order to expand our network, we
intend to enter into a number of strategic partnerships which will involve the
payment of significant funds for prominent or exclusive carriage of our
healthcare information and services. These transactions are premised on the
assumption that the traffic we obtain from these arrangements will permit us to
earn revenues in excess of the payments made to partners. This assumption is not
yet proven, and if we are unsuccessful in generating sufficient resources to
offset these expenditures, we will likely be unable to continue to operate our
business.

         IN ORDER TO ATTRACT AND RETAIN OUR AUDIENCE OF USERS, WE MUST PROVIDE
HEALTHCARE CONTENT, TOOLS AND OTHER FEATURES WHICH MEET THE CHANGING DEMANDS OF
THOSE USERS. One of our fundamental business objectives is for eMD to be a
trusted source for healthcare information, products, and services. As with any
form of consumer-oriented media, we have to provide editorial content,
interactive tools and other features that consumers demand in order to continue
to attract and retain our audience of users. We expect that competitive factors

continuing need for us to retain, improve and add to our editorial content,
interactive tools and other features. We will not only have to expend
significant funds and other resources to continue to improve our network, but we
must also properly anticipate and respond to consumer preferences and demands.
Competition for content will likely increase the fees charged by high quality
content providers. The addition of new features will also require that we
continue to improve the technology underlying our website. These requirements
are significant, and we may fail to execute on them quickly and efficiently. If
we fail to expand the breadth of our offerings quickly, or these offerings fail
to achieve market acceptance, our business will suffer significantly.

         WE DEPEND ON THIRD-PARTY RELATIONSHIPS, MANY OF WHICH ARE SHORT-TERM OR
TERMINABLE, TO PROVIDE US WITH CONTENT AND GENERATE REVENUE. We will depend on a
number of third-party relationships to increase traffic on eMD and thereby
generate revenues. Outside parties on which we depend include unrelated website
operators that provide links to eMD and providers of healthcare content. Many of
our arrangements with third-party internet sites and other third-party service
providers are not exclusive and are short-term or may be terminated at the
convenience of either party. We cannot assure you that third parties regard our
relationship with them as important to their own respective businesses and
operations. They may reassess their commitment to us at any time in the future
and may develop their own competitive services or products.

         We intend to produce only a portion of the healthcare content that will
be found on the eMD website. We will rely on third-party organizations that have
the appropriate expertise, technical capability, name recognition, reputation
for integrity, and willingness to syndicate product content for branding and
distribution by others. As health-related content grows on the internet, we
believe that there will be increasing competition for the best product
suppliers, which may result in a competitor acquiring a key supplier on an
exclusive basis, or in significantly higher content prices. Such an outcome
could make the eMD website and related services less attractive or useful for an
end user which could reduce our e-commerce revenues.

         We cannot assure you that we will be able to maintain relationships
with third parties that supply us with content, software or related products or
services that are crucial to our success, or that this content, software,
products or services will be able to sustain any third-party claims or rights
against their use. Also, we cannot assure you that the content, software,
products or services of those companies that provide access or links to our
website will achieve market acceptance or commercial success. Accordingly, we
cannot assure you that our existing relationships will result in sustained
business partnerships, successful product or service offerings or the generation
of significant revenues for us.

         WE HAVE RECENTLY EXPERIENCED AND ARE LIKELY TO CONTINUE TO EXPERIENCE
RAPID GROWTH IN OUR BUSINESS. We have experienced and are likely to continue to
experience significant growth. Our ability to manage this growth is critical to
our business. This growth has placed, and the future growth we anticipate in our
operations will continue to place, a significant strain on our resources. As
part of this growth, we will have to implement new operational and financial
systems and procedures and controls, expand, train and manage our employee base,
and maintain close coordination among our technical, accounting, finance,
marketing, sales and editorial staffs. If we are unable to manage our growth
effectively, our business, results of operations and financial condition could
be adversely affected.

         Several members of our senior management joined us in 1999 and 2000,
including Sharon Allred, Senior Vice President, Scott Parliament, Chief
Financial Officer and Geoffrey Faux, President of eMD. These individuals are
currently becoming integrated with the other members of our management team. We
cannot assure you that our management team will be able to work together
effectively or successfully manage our growth. We believe that the successful
integration of our management team is critical to our ability to effectively
manage our operations and support our anticipated future growth.

         IF WE CANNOT EXPAND OUR NETWORK INFRASTRUCTURE, WE COULD LOSE
CUSTOMERS. We must continue to expand and adapt our network infrastructure to
accommodate additional users, increase transaction volumes and meet changing
consumer and customer requirements. We may not be able to accurately project the
rate or timing of increases, if any, in the use of our website or to expand and
upgrade our systems and infrastructure to accommodate these increases. Our
systems may not accommodate increased use while maintaining acceptable overall
performance. Service lapses could cause our users to instead use the on-line
services of our competitors. Any service lapses may have a material adverse
effect on our business.

         WE MAY HAVE LIABILITY FOR INFORMATION WE PROVIDE ON OUR WEBSITE OR
WHICH IS ACCESSED FROM OUR WEBSITE. Because users of our website access health
content and services relating to a condition they may have or may distribute our
content to others, third parties may sue us for defamation, negligence,
copyright or trademark infringement, personal injury or other matters. We could
also become liable if we improperly or wrongfully disclose confidential
information. These types of claims have been brought, sometimes successfully,
against on-line services in the past. Others could also sue us for the content
and services that are accessible from our website through links to other
websites or through content and materials that may be posted by our users in
chat rooms or bulletin boards. While our agreements, including those with
content providers, in some cases provide that we will be indemnified against
these liabilities, this indemnification, if available, may not be adequate. Our
insurance may not adequately protect us against these types of claims. Further,
our business is based on establishing the eMD network as a trustworthy and
dependable provider of healthcare information and services. Allegations of
impropriety, even if unfounded, could therefore have a material adverse effect
on our reputation and our business.

         ANY FAILURE OR INABILITY TO PROTECT OUR INTELLECTUAL PROPERTY RIGHTS
COULD ADVERSELY AFFECT OUR ABILITY TO ESTABLISH OUR BRAND. Our intellectual
property is important to our business. We rely on a combination of copyright,
trademark and trade secret laws, confidentiality procedures and contractual
provisions to protect our intellectual property. Federal registrations are
pending for eMD as well as other service and trademarks. If we lose our right to
use the eMD name, we would be forced to change our corporate name and adopt a
new domain name. These changes could confuse current and potential customers and
would adversely impact our business. We also rely on a variety of technologies
that are licensed from third parties, including our database and internet server
software, which is used in the eMD website to perform key functions. These
third-party licenses may not be available to us on commercially reasonable terms
in the future.



RISKS RELATED TO THE ARROW MAGNOLIA TRANSACTION

         THE INTEGRATION OF ARROW MAGNOLIA INTERNATIONAL, INC. INTO OUR
OPERATIONS MAY NOT BE SUCCESSFUL, AND MAY DISRUPT OUR EXISTING BUSINESS. On July
7, 2000, we announced an agreement to acquire up to 85% of the outstanding stock
of Arrow Magnolia International, Inc., a company engaged primarily in the
manufacture and distribution of specialty chemical products for use in cleaning
and maintaining equipment and generalized maintenance and sanitation products,
for cash and stock. The success of that acquisition, if completed, will depend
in part on our ability to realize the anticipated growth opportunities and
synergies from combining the businesses of BioShield and Arrow Magnolia. Among
other things, the integration of Arrow Magnolia's and BioShield's business may
result in disruption of our existing business, distraction of our management and
diversion of other resources.

         WE WILL HAVE TO AMORTIZE GOODWILL THAT WILL INCREASE OUR NET LOSSES. If
the Arrow Magnolia acquisition is completed, the combined company's reported
financial results will suffer as a result of purchase accounting treatment of
the Arrow Magnolia acquisition and the impact of amortization of goodwill and
other intangibles relating to the proposed acquisition. BioShield will account
for the acquisition of Arrow Magnolia using the purchase method of accounting.
As a result, BioShield will record the fair value of the consideration given for
the Arrow Magnolia common stock and for options to purchase Arrow Magnolia
common stock, plus the amount of direct transaction costs, as the cost of
acquiring Arrow Magnolia. BioShield will allocate these costs to the individual
Arrow Magnolia assets acquired and liabilities assumed, including intangible
assets. Intangible assets, including goodwill, will be generally amortized over
a three- to seven-year period.

         As described in the unaudited pro forma condensed combined financial
statements included in this joint proxy statement/prospectus, the amount of
purchase cost allocated to goodwill and other intangibles in the Arrow Magnolia
transaction is estimated to be $10.6 million. If goodwill and other intangible
assets were amortized in equal quarterly amounts following completion of the
acquisition, the accounting charge attributable to these items would be
approximately $0.5 million per quarter or $2.1 million per fiscal year. As a
result, purchase accounting treatment of the Arrow Magnolia acquisition will
result in a net loss for BioShield in the foreseeable future which could have a
material and adverse effect on the market value of BioShield common stock
following completion of the merger.

         COMPLETION OF THE ARROW MAGNOLIA ACQUISITION MAY CAUSE A BREACH UNDER
AGREEMENTS TO WHICH ARROW MAGNOLIA IS A PARTY. The completion of the Arrow
Magnolia acquisition may violate the terms of agreements to which Arrow Magnolia
is a party, or may permit the counterparties to these agreements to exercise


                                       32
<PAGE>   45

their contractual remedies, such as acceleration of rights or termination. We
will attempt to obtain the consent or waiver of the counterparties to these
agreements, but we may be unsuccessful in our attempts. In addition, various
persons with whom Arrow Magnolia historically has had business relationships may
attempt to be released from, or fail to perform their obligations under, their
contracts as a result of the merger, even if the terms of their contracts with
Arrow Magnolia do not allow a release. If we are not able to obtain consents or
waivers from the counterparties to Arrow Magnolia's contracts, or if a
sufficient number of Arrow Magnolia's business partners refuse to perform their
obligations, our business, financial condition and results of operations may be
adversely affected.

         BECAUSE THE COMBINED COMPANY WILL BE A NEWLY INTEGRATED ENTITY, THE
HISTORICAL AND PRO FORMA FINANCIAL STATEMENTS IN THIS PROXY STATEMENT/PROSPECTUS
MAY BE OF LIMITED VALUE IN EVALUATING OUR FUTURE PERFORMANCE. The combination of
BioShield and Arrow Magnolia will result in a new enterprise that has not
operated before as a single integrated unit. As a result, the financial
information in this joint proxy statement/prospectus concerning the individual
operations of Arrow Magnolia and BioShield and the pro forma financial
information concerning the combined entity may be of limited value in evaluating
our financial and operating prospects in the future.

                          THE BIOSHIELD ANNUAL MEETING


DATES, TIMES AND PLACES

         We are providing this joint proxy statement/prospectus to you in

                  Georgia law;

         -        to confirm the issuance of eMD common stock, which is

                  stock and the exercise of the warrants;

         -        to confirm separately two equity credit agreements, which
                  allow BioShield to issue common stock from time to time and to
                  approve the issuance of shares of BioShield common stock in
                  excess of 19.99% of the then-outstanding shares, if required
                  in connection with either of the equity credit agreements;

         -        to confirm the issuance of shares of a series of BioShield
                  convertible preferred stock, and to approve the issuance of

                  conversion of the preferred stock;

         -        to confirm amendments to increase the number of shares
                  reserved for issuance under BioShield's stock plan from

                  more than 10% of BioShield's stock to participate in the plan;

         -        to confirm the appointment of Grant Thornton LLP as
                  BioShield's independent accountants for the fiscal year ending
                  June 30, 2000; and

         -        to transact any other business as may properly be brought
                  before the annual meeting and any adjournments or
                  postponements.


RECORD DATE

         The BioShield board of directors fixed the close of business on [    ],
2000 as the record date for the annual meeting. Accordingly, only holders of
BioShield common stock of record at the close of business on [      ], 2000 will
be entitled to notice of, and to vote at, the annual meeting.


STOCKHOLDERS ENTITLED TO VOTE

         As of the close of business on the record date, there were [          ]
shares of BioShield common stock outstanding and entitled to vote. The holders
of shares of BioShield common stock are entitled to cast one vote for each share
of BioShield common stock they hold on each matter submitted to BioShield's
common stockholders for


                                       34
<PAGE>   47

a vote at the annual meeting. The presence in person or by proxy of a majority
of the shares of BioShield common stock entitled to vote is necessary to
constitute a quorum for the transaction of business at the annual meeting.


REQUIRED VOTE

         The affirmative vote of the holders of a majority of the outstanding
shares of BioShield common stock is necessary to approve and adopt the first
proposal, to issue shares of BioShield common stock necessary to complete the
merger with AHT, and to approve the third proposal, to amend the articles of
incorporation and bylaws to provide that holders of 10 percent or more of
BioShield's capital stock may call a special meeting of stockholders and to
eliminate fair price requirements enacted by BioShield pursuant to Georgia law.
A plurality of the votes present in person or represented by proxy and entitled
to vote is required to approve the second proposal, the election of five
directors to the BioShield board of directors. A majority of the total votes
cast on the proposal is required for approval of the fourth, fifth and sixth
proposals, to confirm the issuance of eMD common stock and related warrants, and
the issuance of shares of BioShield common stock in excess of 19.99 percent of
the outstanding shares, if required in connection with the exchange of the eMD
common stock and exercise of the warrants; to confirm, as separate matters, two
equity credit agreements, under which shares of BioShield common stock may be
issued from time to time, and the issuance of shares of BioShield common stock
in excess of 19.99 percent of the then-outstanding shares, if required in
connection with either of the equity credit agreements; and to confirm the
issuance of shares of a series of convertible preferred stock and the issuance
of shares of BioShield common stock in excess of 19.99 percent of the
then-outstanding shares of BioShield common stock, if required in connection
with the conversion of the preferred stock. The affirmative vote of a majority
of the votes present in person or represented by proxy and entitled to vote is
required to approve the seventh and eighth proposals, to confirm amendments to
BioShield's stock incentive plan to increase the number of shares reserved for
issuance thereunder from 400,000 shares to 2,000,000 shares and to allow holders
of more than 10% of BioShield's outstanding common stock to participate in the
plan; and to confirm the appointment of BioShield's independent accountants.

         Abstentions and broker non-votes will be treated as shares that are
present, in person or by proxy, and entitled to vote for purposes of determining
the presence of a quorum at the annual meeting. As a result, abstentions and
broker non-votes will have the same effect as a vote against the first, third,
seventh and eighth proposals. Abstentions and broker non-votes on the other
proposals will not have any effect on the approval of those proposals.

         As of June 30, 2000, directors, executive officers and affiliates of
BioShield beneficially owned 3,797,672 shares of BioShield common stock, or
approximately 45.6% of the shares of BioShield common stock outstanding. Based
on the 8,403,073 shares of BioShield common stock outstanding as of July 31,
2000, a total of 4,201,537 shares of BioShield common stock must be voted in
favor of the merger agreement and the merger in order for the merger agreement
and the merger to be approved.

         More detailed information with respect to beneficial ownership of
BioShield common stock by directors and executive officers of BioShield appears
in this joint proxy statement/prospectus under "Beneficial ownership of
BioShield common stock" on page ___ of this joint proxy statement/prospectus.


PROXIES OF BIOSHIELD

         This joint proxy statement/prospectus is accompanied by a form of proxy
to be used at the annual meeting. Please complete, date and sign the
accompanying proxy and promptly return it in the enclosed envelope. All shares
of BioShield common stock entitled to vote and represented at the annual meeting
by properly executed proxies received before or at the meeting, and not revoked,
will be voted at the meeting according to the instructions indicated on the
proxies. If a proxy is properly executed but no vote is specified, the proxy
will be voted for issuance of the shares of BioShield common stock upon
completion of the merger.

         You may also place your vote in person at the BioShield annual meeting.
Please note, however, that if your shares are held of record by a broker, bank
or other nominee and you wish to vote at the BioShield annual meeting, you must
bring to the annual meeting a letter from the broker, bank or other nominee
confirming your beneficial ownership of the shares.


                                       35
<PAGE>   48

         If any other matters are properly presented for consideration at the
annual meeting, the persons named in the enclosed form of proxy will have the
discretion to vote on those matters using their best judgment. Additional
matters which may come before the meeting include consideration of a motion to
adjourn the meeting to another time or place, which may be necessary to
disseminate information regarding material developments relating to the merger
agreement or to solicit additional proxies from you. No proxy that has been
voted against the issuance of the shares of BioShield common stock upon
completion of the merger will be voted in favor of any adjournment for the
purpose of soliciting additional votes in favor of issuing shares of BioShield
common stock upon completion of the Merger. If the BioShield annual meeting is
reconvened at a later date, all proxies will be voted as they would have been
voted when the BioShield annual meeting originally occurred, except for proxies
revoked or withdrawn prior to the reconvened BioShield annual meeting.


REVOCATION OF PROXIES

         Any proxy you give with this solicitation may be revoked at any time
before it is voted at the BioShield annual meeting or at any adjournment of the
annual meeting. To revoke a proxy, you must:

         -        sign and deliver a proxy relating to the same shares and
                  bearing a later date prior to the vote at the BioShield annual
                  meeting;

         -        deliver written notice of revocation to Scott Parliament,
                  Chief Financial Officer, at any time before the vote at the
                  BioShield annual meeting; or

         -        attend the BioShield annual meeting and vote in person. Your
                  attendance at the BioShield annual meeting alone is not
                  sufficient to revoke a proxy.

         Any written notice of revocation or new proxy must be delivered at or
before the taking of the vote at the annual meeting to BioShield Technologies,
Inc., 5655 Peachtree Parkway, Norcross, Georgia 30092, Attention: Scott
Parliament, Chief Financial Officer. If you have instructed a broker to vote
your shares, you must follow directions received from your broker to change your
vote.


EXPENSES OF SOLICITATION

         BioShield will pay the expenses of the solicitation of proxies for the
BioShield annual meeting, including a portion of the cost of printing and
mailing this joint proxy statement/prospectus.


PROPOSALS TO BE SUBMITTED FOR THE APPROVAL OF BIOSHIELD'S STOCKHOLDERS AT
BIOSHIELD'S ANNUAL MEETING.

         APPROVAL OF THE ISSUANCE OF BIOSHIELD COMMON STOCK IN CONNECTION WITH
THE MERGER. The board of directors of BioShield has adopted and approved the
merger and the merger agreement in which BioShield will acquire AHT through its
wholly-owned subsidiary, AHT Acquisition Corp. For information regarding the
terms of the merger and the merger agreement, please refer to "The merger
agreement" on page ___ of this joint proxy statement/prospectus.

         The BioShield board of directors has unanimously determined that the
terms of the merger agreement and the merger are fair to and in the best
interests of BioShield and AHT's common stockholders.

       THE BIOSHIELD BOARD OF DIRECTORS RECOMMENDS THAT BIOSHIELD'S COMMON
    STOCKHOLDERS VOTE "FOR" THE PROPOSAL TO ISSUE SHARES OF BIOSHIELD COMMON
                      STOCK UPON COMPLETION OF THE MERGER.



         ELECTION OF DIRECTORS. BioShield's articles of incorporation provide
that the board of directors will consist of no less than three, or more than
twenty-one, directors. The board of directors currently consists of five
directors, divided into three classes, which each serve a three year term. The
current directors are Martin Savarick, Carl T. Garner, Edward U. Miller, Tim
Moses and Hugh R. Lamle. At the annual meeting, you will elect one director


                                       36
<PAGE>   49

whose term will expire in 2001, two directors whose term will expire in 2002 and
two directors whose terms will expire in 2003. The BioShield board of directors
nominates the current directors for re-election. Unless otherwise instructed on
the proxy, properly executed proxies will be voted for the election of the
BioShield board's nominees as directors. The BioShield board of directors
believes that these nominees will stand for reelection and will serve if
elected. However, if any of the nominees fails to stand for reelection or is
unable to accept election, proxies will be voted by the proxy holders for the
election of other people nominated by the BioShield board of directors.


         The following table sets forth information regarding the BioShield
board of director's nominees for election as director:

               THE BIOSHIELD BOARD OF DIRECTORS RECOMMENDS A VOTE
                "FOR" THE ELECTION OF ITS NOMINEES FOR DIRECTOR.




         AMENDMENT OF BIOSHIELD'S ARTICLES OF INCORPORATION AND BY-LAWS. In
connection with BioShield's initial public offering of stock, and specifically
the qualification of the sale of BioShield's securities under the securities
laws of California, BioShield agreed to submit to its stockholders the following
proposals to amend its articles and by-laws:

         -        to allow the holders of 10% or more of the outstanding shares
                  of BioShield's capital stock to call a special stockholders'
                  meeting; and

         -        to eliminate the fair price requirements enacted by BioShield
                  pursuant to Georgia law. These fair price requirements
                  encourage any person, before acquiring 15% or more of
                  BioShield's outstanding common stock, to seek approval of
                  BioShield's board of directors for the terms of any
                  contemplated business combination. One of the effects of these
                  provisions is to prohibit any business combination with an
                  interested stockholder for five years without obtaining the
                  approval of the BioShield board of directors or BioShield's
                  stockholders.

         A copy of the proposed amendments to our articles of incorporation and
by-laws are attached as Appendix D and Appendix E to this joint proxy
statement/prospectus.

         Tim Moses and Jacques Elfersy, substantial BioShield stockholders, have
agreed to vote their shares in favor of this proposal. Approval of this proposal
will require a majority vote of BioShield's stockholders. In the


                                       37
<PAGE>   50

event that this proposal is adopted, BioShield may be more vulnerable to, among
other things, a hostile takeover or other business combination or transaction
that is not approved by BioShield's board of directors.


   THE BIOSHIELD BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE AMENDMENT OF
                   ITS ARTICLES OF INCORPORATION AND BY-LAWS.




         APPROVAL OF THE ISSUANCE OF COMMON STOCK OF EMD AND RELATED WARRANTS
AND AUTHORIZATION OF THE ISSUANCE OF SHARES OF BIOSHIELD COMMON STOCK ISSUABLE
UPON EXCHANGE OF EMD COMMON STOCK. In June 1999, BioShield entered into a
private placement agreement providing for the sale of up to $15,000,000 of
common stock and warrants of eMD. As of the date of this joint proxy
statement/prospectus, we have sold $6,000,000 of eMD common stock and warrants
under the private placement agreement. These shares of stock and warrants are
exempt from registration under Regulation D of the Securities Act.

         Under the terms of the private placement agreements, the eMD stock is
exchangeable for common stock of BioShield, at the option of the holder, at a
conversion price of $5.825 per share of eMD common stock.. This amount
represents 125% of the initial purchase price of $4.66 per share of eMD common
stock. The number of shares of BioShield common stock into which the eMD common
stock is convertible is calculated based upon the average closing bid prices of
BioShield's common stock for the twenty trading days immediately prior to notice
of exercise of the conversion right. No holder of eMD common stock is entitled
to exchange an amount of that stock which would cause the total number of
BioShield shares beneficially owned by the holder and its affiliates to exceed
4.9% of the outstanding shares of BioShield common stock following the
conversion. In addition, any holder of eMD common stock is not entitled to
exchange more than 10% of the total number of shares of eMD common stock issued
to the holder, or any successor or assignee of the holder, in any thirty day
period. BioShield has the option to pay cash to the holders of eMD common stock
seeking to effect a conversion at a rate of $5.825 per share instead of issuing
shares of BioShield common stock. BioShield has the right, at any time, to
redeem any or all of the eMD stock at a price of $5.825 per share, subject to
specified conditions, including having cash, credit facilities or standby
underwriting arrangements in place that are sufficient to pay the redemption
price. Under the terms of the private placement agreements, BioShield has filed
a registration statement with the SEC registering up to one million shares of
BioShield common stock that would be issuable upon the exchange of the eMD
stock.

         BioShield has the right to suspend the exchange of the eMD common stock
for BioShield common stock if eMD becomes and remains a reporting company under
the Exchange Act and the shares of eMD common stock have a trading price of
$6.19 or more per share. The major agreements constituting the private placement
agreement appear in this joint proxy statement/prospectus as Appendices F, G and
H.

         The NASD requires its members, including BioShield, to get the approval
of a majority of the total votes cast before BioShield can issue common stock,
or securities convertible into or exercisable for common stock, if the common
stock issued would be more than 20% of the common stock outstanding, or would
have more than 20% of the voting power outstanding before the issuance. If the
holders of the eMD common stock want to convert their stock into shares of
BioShield common stock, and BioShield is unable to issue all of the common stock
as a result of the NASD rule of BioShield common stock, the holders of eMD
common stock have the option to rescind their election to convert the eMD common
stock, or to cause BioShield to redeem the eMD common stock for cash at a price
of $5.825 per share. Under the terms of the agreements governing the issuance of
the eMD stock, BioShield agreed to submit for stockholder approval a proposal to
ratify the issuance of the eMD stock and the shares of BioShield common stock
issuable upon conversion of the eMD stock. If this proposal is not approved, the
eMD common stock will remain outstanding, but the holders of the eMD common
stock will not be able to convert the eMD common stock into a number of shares
representing more than 19.99% of the BioShield common stock outstanding before
the execution of the private placement agreement unless the stockholders of
BioShield subsequently approve the issuance.

    THE BIOSHIELD BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE PROPOSAL TO
    ISSUE EMD COMMON STOCK AND AUTHORIZE THE ISSUANCE OF SHARES OF BIOSHIELD
          COMMON STOCK ISSUABLE UPON EXCHANGE OF THE EMD COMMON STOCK.




         CONFIRMATION, AS SEPARATE MATTERS, OF TWO EQUITY CREDIT AGREEMENTS AND
APPROVAL OF THE ISSUANCE OF SHARES OF BIOSHIELD COMMON STOCK ISSUABLE IN
CONNECTION WITH THE EQUITY CREDIT AGREEMENTS. In June 1999, BioShield entered
into a private equity credit agreement with an investor. Under the agreement,
the investor has agreed to purchase shares of BioShield common stock during a
24-month period. During the term of the agreement, but no more frequently than
once every 20 trading days, BioShield may require the investor to purchase
between $250,000 and $1.5 million of BioShield common stock until all the
purchases total $10 million, subject to some conditions. To date, BioShield has
sold $2 million under the original terms of the agreement, which allowed the
investor to purchase shares of BioShield common stock for 80% of the then market
price for BioShield common stock. Any additional purchases of BioShield common
stock by the investor will be at a purchase price equal to 90% of the average of
the three lowest average closing bid and ask prices for the 10 trading days
prior to the purchase. Under a related registration rights agreement, BioShield
has filed and agreed to maintain the effectiveness of a registration statement
for the resale by the investor of the shares of BioShield common stock it
purchases under the agreement. If BioShield fails to maintain the effectiveness
of the registration statement, it may be required to pay penalties. This private
equity credit agreement and the related registration rights agreement appear in
this joint proxy statement/prospectus as Appendices I and J.

         In June 2000, BioShield entered into a similar private equity credit
agreement with the investor. Under the agreement, the investor has agreed to
purchase shares of BioShield common stock during a 24-month period. During the
term of the agreement, but no more frequently than once every 20 trading days,
BioShield may require the investor to purchase between $250,000 and $5 million
of BioShield common stock until all the purchases total $50 million. The
purchase price for each share will equal 90% of the average of the three lowest
average closing bid and ask prices for the 10 trading days prior to each draw.
Under a related registration rights agreement, BioShield has agreed to file and
maintain the effectiveness of a registration statement for the resale by the
investor of the shares it purchases under the agreement. If, after the
registration statement becomes effective, BioShield fails to maintain its
effectiveness, BioShield may be required to pay penalties. In connection with
the private equity credit agreement, we issued warrants to the investor to
purchase up to 250,000 shares of common stock of BioShield until June 14, 2005,
at an exercise price of $18.92 per share, subject to adjustment under some
circumstances. This private equity credit agreement, the related registration
rights agreement and the warrant agreement appear in this joint proxy
statement/prospectus as Appendices K, L and M.

         The NASD requires its members, including BioShield, to get the approval
of a majority of the total votes cast before BioShield can issue common stock,
or securities convertible into or exercisable for common stock, if the common
stock issued would be more than 20% of the common stock outstanding, or would
have more than 20% of the voting power outstanding before the issuance. If this
proposal is not approved, BioShield may issue shares under each of the equity
credit agreements, but it may not issue shares under either equity credit
agreement representing more than 19.99% of the BioShield common stock
outstanding before the execution of that equity credit agreement unless the
stockholders of BioShield subsequently approve the issuance.


    THE BIOSHIELD BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE PROPOSAL TO
   RATIFY TWO EQUITY CREDIT AGREEMENTS AND THE ISSUANCE OF SHARES OF BIOSHIELD
     COMMON STOCK ISSUABLE IN CONNECTION WITH THE EQUITY CREDIT AGREEMENTS.




         CONFIRMATION OF THE ISSUANCE OF SHARES OF BIOSHIELD CONVERTIBLE
PREFERRED STOCK, AND APPROVAL OF THE ISSUANCE OF SHARES OF BIOSHIELD COMMON
STOCK ISSUABLE UPON CONVERSION OF THE PREFERRED STOCK. On June 14, 2000,
BioShield completed a private placement for cash of $10 million principal amount
of BioShield series B convertible preferred stock and warrants to purchase
BioShield common stock. The BioShield preferred stock and warrants were exempt
from registration under Regulation D of the Securities Act. Under the terms of
the private


                                       39
<PAGE>   52

placement agreements governing the issuance of the preferred stock and the
warrants, BioShield is required to file a registration statement with the SEC to
register for resale up to 1,500,000 shares of BioShield common stock issuable
upon conversion of the BioShield preferred stock and exercise of the warrants.
The BioShield articles of amendment which describe the designations, preferences
and rights of the preferred stock appear in this joint proxy
statement/prospectus as Appendix N, and the form of warrant agreement as
Appendix O.

         The BioShield preferred stock is convertible into BioShield common
stock until June 14, 2003, at the option of the holder, at a conversion price
equal to a market conversion price that may not exceed $19.70. The market
conversion price is 90% of the average of the closing bid and ask prices of the
BioShield common stock during any 3 trading days during the 10 consecutive
trading days immediately prior to the conversion date. The BioShield preferred
stock is redeemable at BioShield's option, at a price of 125% of its principal
amount, after the registration statement covering the shares of BioShield common
stock issuable upon conversion of the BioShield preferred stock and the warrants
becomes effective with the SEC or 90 days have passed since the issue date. The
warrants entitle the investor to purchase a total of 79,281 shares of BioShield
common stock at the option of the holder until June 14, 2005, at an exercise
price of $18.92 per share, subject to adjustment under some circumstances.

         The NASD requires its members, including BioShield, to get the approval
of a majority of the total votes cast before BioShield can issue common stock,
or securities convertible into or exercisable for common stock, if the common
stock issued would be more than 20% of the common stock outstanding, or would
have more than 20% of the voting power outstanding before the issuance. The
shares of BioShield preferred stock are not convertible into BioShield common
stock to the extent the number of shares of BioShield common stock issuable upon
the conversion would exceed 19.99% of the shares of BioShield common stock
outstanding as of the time of issuance of the BioShield preferred stock, unless
the stockholders of BioShield subsequently approve the issuance of BioShield
common stock. Under the terms of the agreements governing the issuance of the
BioShield preferred stock and the warrants, BioShield agreed to submit for
stockholder approval a proposal to ratify the issuance of the BioShield
preferred stock and the shares of BioShield common stock issuable upon
conversion of BioShield preferred stock.

         If all the shares of BioShield preferred stock were converted, and all
the warrants exercised, as of July 31, 2000, BioShield would be required to
issue approximately 1,423,000 shares of BioShield common stock, or approximately
14.5% of the number of shares of BioShield common stock that would then be
outstanding, without giving effect to the AHT merger or the acquisition of
shares of Arrow Magnolia. The total number of shares of BioShield common stock
issuable upon the conversion and exercise will vary, based upon the closing bid
and ask prices of the BioShield common stock. If this proposal is not approved,
the BioShield preferred stock will remain outstanding, but the holders of the
BioShield preferred stock will not be able to convert the BioShield preferred
stock into a number of shares representing more than 19.99% of the shares
outstanding as of the time of issuance of the BioShield preferred stock, unless
the stockholders of BioShield subsequently approve the issuance.


    THE BIOSHIELD BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE PROPOSAL TO
     CONFIRM THE ISSUANCE OF SHARES OF CONVERTIBLE PREFERRED STOCK AND THE
  ISSUANCE OF SHARES OF BIOSHIELD COMMON STOCK ISSUABLE UPON CONVERSION OF THE
                          CONVERTIBLE PREFERRED STOCK.




         CONFIRMATION OF AMENDMENTS TO THE STOCK INCENTIVE PLAN. The BioShield
board of directors have adopted amendments to BioShield's 1997 stock incentive
plan to increase the number of shares reserved for issuance pursuant to options
granted under the plan from 400,000 shares to 2,000,000 shares, and to allow
holders of more than 10% of the outstanding shares of BioShield common stock to
participate in the plan. The stock incentive plan, as amended, appears in this
proxy statement as Appendix P, and is summarized on page [ ] of this joint proxy
statement/prospectus under "Stock option plans."

         The stock incentive plan provides BioShield with increased flexibility
to grant equity-based compensation to key employees, officers and consultants of
BioShield. The purpose of the plan is:

         -        to provide incentives to stimulate individual efforts toward
                  BioShield's long-term growth and profitability;


                                       40
<PAGE>   53

         -        to encourage stock ownership by officers, key employees and
                  consultants by enabling them to acquire a proprietary interest
                  in BioShield in the form of shares of BioShield common stock
                  or to receive compensation based on appreciation in the value
                  of the BioShield common stock; and

         -        to provide a means of obtaining, rewarding and retaining key
                  personnel.

         The affirmative vote of a majority of the total votes cast on the
proposal in person or by proxy is required to approve this proposal.


    THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE PROPOSAL TO RATIFY AN
                     AMENDMENT TO THE STOCK INCENTIVE PLAN.



         CONFIRMATION OF APPOINTMENT OF GRANT THORNTON LLP AS INDEPENDENT
ACCOUNTANTS. The BioShield board of directors has appointed Grant Thornton LLP
as independent accountants to audit the consolidated financial statements of
BioShield for the fiscal year beginning July 1, 1999. Stockholders are asked to
confirm this appointment. Representatives of Grant Thornton LLP are expected to
be present at the annual meeting, will have the opportunity to make a statement
if they desire to do so, and will be available to respond to appropriate
questions.


    THE BIOSHIELD BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE PROPOSAL TO
               RATIFY THE APPOINTMENT OF INDEPENDENT ACCOUNTANTS.

                             THE AHT SPECIAL MEETING


DATES, TIMES AND PLACES

         We are providing this joint proxy statement/prospectus to you in
connection with the solicitation of proxies by the AHT board of directors in
connection with the proposed merger between AHT and BioShield, through its
wholly owned subsidiary AHT Acquisition Corp. These proxies are for use at the
special meeting to be held on [date], 2000 at [time], local time, at the
Tarrytown Hilton, 455 South Broadway, Tarrytown, New York 10591 and at any
adjournments or postponements thereof.


PURPOSE OF THE AHT SPECIAL MEETING

         At the AHT special meeting, the AHT board of directors will ask you to
consider and vote upon a proposal to approve and adopt the merger agreement and
the merger described in this joint proxy statement/prospectus.


RECORD DATE

         The AHT board of directors fixed the close of business on [ ], 2000 as
the record date for the special meeting. Accordingly, only holders of AHT common
stock of record at the close of business on [ ], 2000 will be entitled to notice
of, and to vote at, the special meeting.


STOCKHOLDERS ENTITLED TO VOTE

         As of the close of business on the record date, there were [ ] shares
of AHT common stock outstanding and entitled to vote. The holders of common
stock are entitled to cast one vote for each share of common stock they hold on
each matter submitted to the common stockholders for a vote at the special
meeting. The presence in person or by proxy of a majority of the shares of AHT
common stock entitled to vote is necessary to constitute a quorum for the
transaction of business at the special meeting.

         AHT will count shares of AHT common stock represented in person or by
proxy for the purpose of determining whether a quorum is present at the special
meeting. AHT will also treat shares that abstain from voting as shares that are
present and entitled to vote at the special meeting for purposes of determining
whether a quorum exists. If you abstain from voting, that abstention will have
the practical effect of voting against the adoption and approval of the merger
agreement and the merger.


REQUIRED VOTE

         Adoption and approval of the merger agreement and the merger under
AHT's amended and restated certificate of incorporation requires the affirmative
vote of the holders of a majority of the outstanding shares of AHT's common
stock.

         If you fail to vote or if you respond and abstain from voting it will
have the same effect as a vote against the merger agreement and the merger. If
you return your proxy and do not indicate how you want to vote, your proxy will
be counted as a vote to adopt and approve the merger agreement and the merger.

         As of July 21, 2000, directors, executive officers and affiliates of
AHT beneficially owned 856,441 shares of AHT common stock, or approximately 7.7%
of the shares of AHT common stock outstanding. Based on the 11,130,449 shares of
AHT common stock outstanding as of July 21, 2000, a total of 5,565,225 shares of
AHT common stock must be voted in favor of the merger agreement and the merger
in order for the merger agreement and the merger to be approved.

         More detailed information with respect to beneficial ownership of AHT
common stock by directors and executive officers of AHT is incorporated by
reference to AHT's definitive Proxy Statement dated June 22, 2000.

         As of the date of this joint proxy statement/prospectus, BioShield has
no direct or indirect interest in any AHT securities.

of AHT common stock entitled to vote and represented at the special meeting by
properly executed proxies received before or at the meeting, and not revoked,
will be voted at the meeting according to the instructions indicated on the
proxies. If a proxy is properly executed but no vote is specified, the proxy
will be voted for adoption of the merger agreement and adoption and approval of
the merger.

         You may also place your vote in person at the AHT special meeting.
Please note, however, that if your shares are held of record by a broker, bank
or other nominee and you wish to vote at the AHT special meeting, you must bring

confirming your beneficial ownership of the shares.

         If any other matters are properly presented for consideration at the
special meeting, the persons named in the enclosed form of proxy will have the
discretion to vote on those matters using their best judgment. Additional
matters which may come before the meeting include consideration of a motion to
adjourn the meeting to another time or place, which may be necessary to
disseminate information regarding material developments relating to the merger
agreement or to solicit additional proxies from you. No proxy that has been
voted against the adoption and approval of the merger agreement and merger will
be voted in favor of any adjournment for the purpose of soliciting additional
votes in favor of approving the merger agreement and the merger. If the AHT
special meeting is reconvened at a later date, all proxies will be voted as they
would have been voted when the AHT special meeting originally occurred, except
for proxies revoked or withdrawn prior to the reconvened AHT special meeting.

         YOU SHOULD NOT SEND IN ANY STOCK CERTIFICATES WITH YOUR PROXIES. A
TRANSMITTAL FORM WITH INSTRUCTIONS FOR THE SURRENDER OF YOUR CERTIFICATES FOR
AHT COMMON STOCK IN EXCHANGE FOR SHARES OF BIOSHIELD COMMON STOCK WILL BE MAILED

REVOCATION OF PROXIES

         Any proxy you give with this solicitation may be revoked at any time

         -        deliver written notice of revocation to Arthur Dague at any
                  time before the vote at the AHT special meeting; or

                  attendance at the AHT special meeting alone is not sufficient
                  to revoke a proxy.

         Any written notice of revocation or new proxy must be delivered at or
before the taking of the vote at the special meeting to AHT Corporation, 555
White Plains Road, Tarrytown, New York 10591, Attention: Arthur Dague. If you
have instructed a broker to vote your shares, you must follow directions
received from your broker to change your vote.

                                   THE MERGER

         This section of the joint proxy statement/prospectus describes the
proposed merger. While we believe that the description covers the material terms
of the merger and the related transactions, this summary may not contain all of
the information that is important to you. You should carefully read this entire
document and the other documents referred in this joint proxy
statement/prospectus for a more complete understanding of the merger. For your
convenience, a copy of the merger agreement is attached as Appendix A.

         In addition, important business and financial information about
BioShield and AHT is incorporated into this joint proxy statement/prospectus by
reference. You may obtain the information incorporated by reference into this
joint proxy statement/prospectus without charge by following the instructions in
the section entitled "Where you can find more information" that begins on page
___ of this joint proxy statement/prospectus.


COMPLETION AND EFFECTIVENESS OF THE MERGER

         If the holders of a majority of the outstanding shares of AHT common
stock entitled to vote at the special meeting adopt and approve the merger
agreement and the merger, if the holders of a majority of the outstanding shares
of BioShield common stock approve the issuance of BioShield common stock in
connection with the merger and if the other conditions described in the merger
agreement are satisfied or waived, AHT will merge with and into AHT Acquisition
Corp, a wholly owned subsidiary of BioShield. As a result of the merger, AHT
will become a wholly owned subsidiary of BioShield. In the merger, holders of
shares of AHT common stock will be entitled to receive from BioShield, in
exchange for each share of AHT common stock that they own, an amount of
BioShield common stock equal to an exchange ratio calculated as described below.
Cash will be issued in place of any fractional shares of BioShield common stock.
The amount of cash to be issued will be determined as calculated below.


BACKGROUND OF THE MERGER

         During the summer of 1999, AHT's senior management began to explore and
analyze AHT's business strategy and discussed potential partnering, business
combinations and other alternatives to maximize stockholder value. These
discussions were consistent with AHT management's past practice of reviewing the
current condition and direction of AHT's business. Based upon its evaluation of
each of the alternatives, management believed that a business combination of AHT
with another company in either the eHealth, healthcare software, pharmacy,
pharmacy benefit management or healthcare services industries could provide the
greatest stockholder value to AHT's stockholders.

         Based on this conclusion, AHT engaged Hambrecht & Quist, LLC, which was
succeeded by Chase H&Q, to act as its exclusive financial advisor in connection
with a potential business combination of AHT. Among other things, Chase H&Q
reviewed AHT's financial plans, strategic plans and business alternatives with
AHT's board of directors and management.

         AHT's management, with the assistance of its financial advisors,
identified several third parties that might have an interest in engaging in a
business combination transaction with AHT. At the request of AHT, Chase H&Q
initiated preliminary discussions with some of these third parties and had
conversations relating to potential business combinations with some of these
companies.

         In early 2000, BioShield, together with its financial advisor, Gruntal,
identified AHT as a potential business partner as part of its continuing efforts
to expand eMD's internet healthcare business. Through Gruntal, BioShield
conducted preliminary discussions with Chase H&Q, which represented AHT at AHT's
request.

         Following these discussions, several third parties, including
BioShield, submitted preliminary indications of interest to acquire AHT.


                                       45
<PAGE>   58

         Throughout the period from the engagement of Chase H&Q through
negotiation and adoption and approval of the merger agreement and the merger,
AHT's management spoke frequently with the AHT board of directors to make sure
that the directors had the most up to date information about the process being
conducted by AHT's management regarding any potential business combination.

         On May 3, 2000, Dr. Jonathan T. Edelson, Chairman, Chief Executive
Officer and President of AHT and Jeffrey M. Sauerhoff, Chief Financial Officer
of AHT, spoke with Tim Moses, President and Chief Executive Officer of
BioShield, Scott Parliament, Chief Financial Officer of BioShield, and Roger
Kahn, BioShield's financial advisor from Gruntal. The parties were introduced
during the call and an overview of the business and operations of both companies
was provided. At the conclusion of the meeting, the parties decided to execute a
mutual non-disclosure agreement, which was signed on May 5, 2000. AHT and
BioShield also agreed to exchange some non-public financial information and
their operating plans.

         On May 9, 2000, Jonathan Edelson, Jeffrey Sauerhoff and Robert Alger,
Chief Information Officer of AHT, met with Timothy Moses, Geoffrey Faux,
President of eMD, a subsidiary of BioShield, and Sharon Allred, Executive Vice
President of eMD, along with their financial advisors from Gruntal, Roger Kahn,
Joe Russo and Peter Fry, to review the businesses of BioShield and AHT in more
detail. In addition, Jonathan Edelson briefly discussed some valuation issues
regarding a proposed transaction between the two companies.

         On May 12, 2000, BioShield submitted in writing to AHT a non-binding
indication of interest to purchase AHT, subject to customary conditions
including an appropriate due diligence review of AHT.

         On May 18, 2000, Jonathan Edelson, Jeffrey Sauerhoff and Eddy
Friedfeld, Senior Vice President, Business and Legal Affairs, and General
Counsel of AHT, met with Timothy Moses and Scott Parliament of BioShield and
BioShield's counsel, Raymond Moss from the law firm of Sims, Moss, Kline, &
Davis LLP. They discussed potential transaction structures, financial
consideration, legal issues and the organization of the company after a business
combination. They also scheduled additional meetings for the following week so
that employees of BioShield could visit AHT's operations in Ft. Washington,
Pennsylvania to review AHT's proprietary software application technology and
products and so that Jonathan Edelson, Jeffrey Sauerhoff and Robert Alger could
visit BioShield's offices in Norcross, Georgia to review BioShield's operations.

         On May 22 and 23, 2000, Jonathan Edelson, Jeffrey Sauerhoff and Robert
Alger met with Geoffry Faux, Scott Parliament, Charles Largay, eMD's Chief
Technology Officer, and Kevin Smith, eMD's Chief Medical Officer, to further
discuss a possible business combination. A representative of Chase H&Q was also
present. The parties discussed, among other things, the financial assumptions to
be made and potential benefits of a business combination.

         On June 8, 2000, BioShield made a second preliminary non-binding offer,
proposing to acquire each share of AHT common stock for $1.25 worth of BioShield
common stock, including the assumption of AHT's debt.

         On June 12, 2000, as a result of negotiations between BioShield and
AHT, BioShield revised its second preliminary offer to acquire each share of AHT
common stock and increased the price from $1.25 to $1.75 worth of BioShield
common stock per share. The financial structure that was discussed included
collar protections for the price per share and other customary terms and
conditions for similar transactions.

         On June 19, 2000, Jonathan Edelson and Robert Alger met with Timothy
Moses and Scott Parliament at BioShield's offices to continue AHT's due
diligence of BioShield and to further discuss the proposed transaction including
the collar mechanism.

         On June 20, 2000, Jeffrey Sauerhoff met with Scott Parliament at
BioShield's offices to review some of BioShield's financial documents as part of
AHT's ongoing due diligence.

         On June 22 and 23, 2000, members of BioShield's due diligence team,
including Gavin Adair and Jason Buerkle from Grant Thornton LLP, BioShield's
auditors, Scott Parliament and Raymond Moss, arrived at AHT's headquarters to
complete BioShield's due diligence and negotiate the terms of a merger document.

         On June 26, 2000, Robert Alger visited BioShield's headquarters to
complete AHT's technical due diligence.

         On June 26, 2000, members of BioShield's technical due diligence team
visited AHT's operations in Ft. Washington and Chicago, Illinois to complete
their technical due diligence.

         On June 28, 29 and 30, 2000, Jonathan Edelson, Jeffrey Sauerhoff and
Eddy Friedfeld, with their counsel, Dominick DeChiara and Alisa Lefkowitz,
attorneys from O'Sullivan Graev & Karabell, LLP, met at AHT's corporate offices
with Geoffry Faux and Scott Parliament, with their counsel, Raymond Moss and
David Mogel, to finalize the merger agreement.

         On June 29, 2000, the AHT board of directors held a special meeting to
discuss the proposed transaction with BioShield and the terms of the merger
agreement. Jonathan Edelson updated the AHT board of directors on the
negotiations with BioShield. Additionally, Jonathan Edelson, with the assistance
of a representative from Chase H&Q, reviewed the strategic and business
rationale for the transaction and AHT's prospects if it continues to operate as
an independent company. The Chase H&Q representative also reviewed Chase H&Q's
contacts with other potential strategic buyers and the likelihood of
consummating a transaction between AHT and any of those third persons. In
addition, the Chase H&Q representative summarized the financial analysis it had
performed related to the proposed transaction and orally delivered Chase H&Q's
financial opinion, which it subsequently confirmed in writing on June 30, 2000,
that the consideration to be received by AHT's stockholders pursuant to the
merger agreement was fair from a financial point of view to AHT's stockholders.
Finally, Dominick DeChiara summarized the terms of the merger agreement and
discussed the directors' fiduciary duties under Delaware law. After discussion
and consideration of the factors and reasons described, the AHT board of
directors unanimously determined that the terms of the merger agreement and the
merger are fair to and in the best interests of AHT and AHT's common
stockholders. Accordingly, the AHT board of directors voted to recommend that
AHT's common stockholders vote for the proposal to approve and adopt the merger
agreement and the merger.

         On June 29, 2000, the BioShield board of directors held a special
meeting to discuss the proposed transaction with AHT and the terms of the merger
agreement. Geoffrey Faux made a presentation to the board regarding the business
of AHT, and Scott Parliament reviewed the potential synergies between the
business of AHT and eMD and the results of the due diligence examination
conducted by BioShield and its advisors. Raymond Moss described some of the
significant terms and conditions of the merger agreement. After discussion and
consideration of those factors, the BioShield board of directors unanimously
determined to approve and adopt the merger agreement, the merger and recommend
the issuance of BioShield common stock in connection with the merger.

         Following the meetings of the AHT and BioShield boards of directors and
completion of a final merger document, on June 30, 2000, AHT and BioShield
executed the merger agreement.


BIOSHIELD'S REASONS FOR THE MERGER

         In reaching its determination to approve and adopt the merger agreement
and the merger, and recommend the issuance of BioShield common stock in
connection with the merger, the BioShield board of directors consulted with
BioShield's management and its financial and legal advisors, and considered a
number of factors. The BioShield board of directors did not assign any relative
or specific weights to the factors considered in reaching their determination,
and individual directors may have given differing weights to different factors.
In its decision to recommend and approve the merger, the BioShield board of
directors considered a number of factors, including:

         1.       the financial condition, results of operations, cash flows,
                  earnings, assets and prospects of AHT and BioShield;

         2.       the expectation that AHT's product and service offerings can
                  be integrated with those of eMD, and expand BioShield's
                  presence in the internet healthcare sector;

         3.       the customer relationships of AHT that were complementary to
                  eMD's, and of significant value in advancing the execution of
                  eMD's business plan;

         4.       the intellectual property rights owned by AHT in the internet
                  healthcare area;


                                       47
<PAGE>   60

         5.       preliminary advice from Gruntal, financial advisor to
                  BioShield, that the consideration to be received by holders of
                  BioShield common stock pursuant to the merger agreement is
                  fair from a financial point of view to BioShield's
                  stockholders;

         6.       current financial market conditions and the historical market
                  prices, volatility and trading information with respect to
                  BioShield common stock, AHT common stock and the internet
                  healthcare sector, in general;

         7.       the BioShield board of directors' expectation that the
                  addition of AHT's operations to eMD may increase the overall
                  value of BioShield, tending to produce greater stockholder
                  value for BioShield's stockholders;

         8.       the fact that the internet healthcare sector, of which eMD is
                  a part, is extremely competitive and is characterized by rapid
                  change and uncertainty due to new and emerging technologies,
                  new and changing business practices and low barriers to entry;

         9.       the nature of the internet healthcare sector and the fact that
                  greater size and resources are increasingly required for
                  companies to successfully compete in this sector;

         10.      the increasing competition in eMD's markets from both existing
                  and potential competitors, some of which have greater assets
                  and resources than eMD, which has occurred as a result of,
                  among other reasons, the consolidation taking place in the
                  internet healthcare industry;

         11.      the opportunity of the combined company to reduce costs
                  through economies of scale that would not have been readily
                  achievable by eMD independently, and the elimination of
                  redundant operations and duplicate administrative functions;

         12.      the presentations by, and discussions of the terms of the
                  merger agreement with, BioShield's senior management,
                  BioShield's legal counsel, Sims Moss Kline & Davis LLP, and
                  Gruntal; and

         13.      the terms and conditions of the merger agreement and the
                  nature of the arm's-length negotiation of the merger
                  agreement.

         The foregoing discussion of the information and factors considered by
the BioShield board is not intended to be exhaustive but is believed to include
all material factors considered by the BioShield board of directors. In view of
the wide variety of factors, both positive and negative, considered by the
BioShield board, the BioShield board did not find it practical to, and did not,
quantify or otherwise assign relative weights to the specific factors
considered. In addition, the BioShield board did not reach any specific
conclusion with respect to each of the factors considered, or any aspect of any
particular factor. Instead, the BioShield board conducted an overall analysis of
the factors described above, including discussions with BioShield's management
and its financial and legal advisors. In considering the factors described
above, individual members of the BioShield board may have given different weight
to different factors. The BioShield board considered all these factors as a
whole and believed the factors supported its determination to approve the
merger. After taking into consideration all of the factors set forth above,
BioShield's board of directors concluded that the merger was fair to, and in the
best interests of, BioShield and its stockholders and that BioShield should
proceed with the merger.


RECOMMENDATION OF BIOSHIELD'S BOARD OF DIRECTORS

         After careful consideration, the BioShield board of directors approved
the merger agreement and the merger, declared that the merger agreement, the
merger and the issuance of shares of BioShield common stock in connection with
the merger are advisable and determined that the merger is fair to, and in the
best interests of, BioShield and the BioShield stockholders. Accordingly, the
BioShield board unanimously recommends that the BioShield stockholders vote
"FOR" approval of the issuance of shares of BioShield common stock in connection
with the merger.

AHT'S REASONS FOR THE MERGER

         In reaching its determination to approve and adopt the merger agreement
and the merger, the AHT board of directors consulted with AHT's management and
its financial and legal advisors, and considered a number of factors. The AHT
board of directors did not assign any relative or specific weights to the
factors considered in reaching their determination, and individual directors may
have given differing weights to different factors. In its decision to recommend
and approve the merger, the AHT board of directors considered a number of
factors, including:

         1.       the financial condition, results of operations, cash flows,
earnings, assets and prospects of AHT;

         2.       the fact that the proposed merger will present the opportunity
for the holders of shares of AHT common stock to participate in a significantly
larger and more diversified company and, as stockholders of the combined
company, to have greater liquidity in their shares and to benefit from any
future growth of the combined company;

         3.       the presentation of Chase H&Q, financial advisor to AHT, and
the opinion of Chase H&Q that, subject to the limitations, considerations and
other matters described in its opinion, the consideration to be received by
holders of AHT common stock pursuant to the merger agreement is fair from a
financial point of view to AHT's stockholders;

         4.       the potential strategic alternatives available to AHT and the
viability and risks associated with each alternative, including the prospects
for AHT on a stand-alone basis and the risks associated with achieving and
executing upon AHT's business plan, both short-term and long-term;

         5.       the belief of AHT's management that, based on its review of
AHT's strategic alternatives and on the information from Chase H&Q regarding its
preliminary contacts with a number of third parties, it is unlikely that any
alternative transaction that may be proposed by any other person would be more
favorable to AHT and its stockholders than the proposed merger with BioShield;

         6.       current financial market conditions and the historical market
prices, volatility and trading information with respect to AHT common stock,
BioShield common stock and the internet healthcare sector, in general;

         7.       the AHT board of directors' expectation that the addition of
AHT's operations to BioShield may increase the overall value and profitability
of BioShield, tending to produce greater stockholder value for AHT's
stockholders;

         8.       the fact that the internet healthcare sector, of which AHT is
a part, is extremely competitive and is characterized by rapid change and
uncertainty due to new and emerging technologies, new and changing business
practices and low barriers to entry;

         9.       the nature of the internet healthcare sector and the fact that
greater size and resources are increasingly required for companies to
successfully compete in this sector;

         10.      the increasing competition in AHT's markets from both existing
and potential competitors, some of which have greater assets and resources than
AHT, which has occurred as a result of, among other reasons, the consolidation
taking place in the internet healthcare industry;

         11.      the challenge for AHT to participate in industry consolidation
as an acquirer, given its capital resources and stock price;

         12.      the opportunity of the combined company to reduce costs
through economies of scale that would not have been readily achievable by AHT
independently, and the elimination of redundant operations and duplicate
administrative functions;

         13.      the fact that, assuming an average closing trading price of
BioShield common stock, as determined in accordance with the merger agreement,
between $6.00 and $18.00 per share, the $1.75 worth of BioShield common stock to
be received for each share of AHT common stock in the merger represented a
premium of approximately


                                       49
<PAGE>   62

47% over the closing price of the AHT common stock on the Nasdaq on June 7,
2000, the day immediately before receipt of the initial offer letter from
BioShield, a premium of approximately 20% over the average closing price of the
AHT common stock on the Nasdaq for the last 40 days of trading prior to June 29,
2000 and a premium of approximately 11% over the average closing price of the
AHT common stock on the Nasdaq for the last 20 days of trading prior to June 29,
2000;

         14.      the presentations by, and discussions of the terms of the
merger agreement with, AHT's senior management and AHT's legal counsel,
O'Sullivan Graev & Karabell, LLP;

         15.      the terms and conditions of the merger agreement and the
nature of the arm's-length negotiation of the merger agreement; and

         16.      the fact that while the merger agreement prohibits AHT from
soliciting proposals concerning an acquisition of AHT, the AHT board of
directors, in the exercise of its fiduciary duties, would be able to provide
information to, and engage in negotiations with, a third party that makes an
unsolicited superior acquisition proposal, and that the AHT board would be able
to terminate the merger agreement and accept a superior acquisition proposal if
it determines that its fiduciary duties so require, upon payment to BioShield of
a termination fee of $600,000, plus reimbursement of BioShield's expenses up to
a maximum of $240,000.

         The foregoing discussion of the information and factors considered by
the AHT board is not intended to be exhaustive but is believed to include all
material factors considered by the AHT board of directors. In view of the wide
variety of factors, both positive and negative, considered by the AHT board, the
AHT board did not find it practical to, and did not, quantify or otherwise
assign relative weights to the specific factors considered. In addition, the AHT
board did not reach any specific conclusion with respect to each of the factors
considered, or any aspect of any particular factor. Instead, the AHT board
conducted an overall analysis of the factors described above, including
discussions with AHT's management and its financial and legal advisors. In
considering the factors described above, individual members of the AHT board may
have given different weight to different factors. The AHT board considered all
these factors as a whole and believed the factors supported its determination to
adopt and approve the merger. After taking into consideration all of the factors
set forth above, AHT's board of directors concluded that the merger was fair to,
and in the best interests of, AHT and its stockholders and that AHT should
proceed with the merger.


RECOMMENDATION OF AHT'S BOARD OF DIRECTORS

         After careful consideration, the AHT board of directors approved the
merger agreement and the merger, declared that the merger agreement and the
merger are advisable and determined that the merger is fair to, and in the best
interests of, AHT and the AHT stockholders. Accordingly, the AHT board
unanimously recommends that the AHT stockholders vote "FOR" approval and
adoption of the merger agreement and the merger.

         In considering the recommendations by AHT's board of directors of the
merger agreement and the merger, you should be aware that some directors and
officers of AHT have interests in the merger that are different from, or are in
addition to, the interests of AHT's stockholders generally. Please see the
section entitled "Interests of AHT's directors, officers and affiliates in the
merger" on page __ of this joint proxy statement/prospectus.

OPINION OF BIOSHIELD'S FINANCIAL ADVISOR

         BioShield engaged Gruntal to act as BioShield's financial advisor in
connection with the proposed merger. Gruntal delivered its written opinion dated
June 30, 2000 to the BioShield board of directors that, as of that date, based
upon and subject to the assumptions made, matters considered and limits of the
review undertaken by Gruntal, the consideration to be received by the holders of
AHT common stock was fair, from a financial point of view, to the holders of
BioShield common stock.

         The full text of Gruntal's opinion dated June 30, 2000, which sets
forth the assumptions made, matters considered and limitations on the review
undertaken is attached as Appendix C to this document and is incorporated in
this summary by reference. BioShield stockholders should read Gruntal's opinion
carefully in its entirety. Gruntal's opinion is directed to BioShield's board
and the fairness of the consideration to be issued to the shareholders of AHT in
the merger from a financial point of view to BioShield's common stockholders,
and does


                                       50
<PAGE>   63

not address any other aspect of the merger nor does it constitute a
recommendation to any BioShield stockholder as to how to vote at the BioShield
annual meeting. The summary of Gruntal's opinion set forth in this document is
qualified in its entirety by reference to the full text of the opinion.

         In arriving at its opinion, Gruntal:

         -        reviewed the merger agreement dated June 30, 2000;

         -        held discussions with members of senior management of
                  BioShield and AHT regarding their respective past and current
                  business operations and their financial conditions and future
                  prospects;

         -        reviewed historical financial and business information
                  provided to them by the management of BioShield and the
                  management of AHT;

         -        reviewed internally prepared financial projections of
                  BioShield and AHT furnished to them by the managements of
                  BioShield and AHT, respectively;

         -        reviewed the historical stock prices and trading volumes of
                  BioShield's and AHT's common stock; o compared the financial
                  performance of AHT and BioShield with that of certain other
                  publicly traded companies comparable to that of each of
                  BioShield and AHT;

         -        reviewed the financial terms, to the extent publicly
                  available, of certain transactions which they considered
                  comparable to the merger; and

         -        conducted other analyses and reviewed other information as
                  Gruntal deemed appropriate.

         In the course of its review, Gruntal has relied upon and assumed the
accuracy and completeness of all the information furnished to it by BioShield
and AHT and has not attempted to independently verify the information. Gruntal
did not make or obtain any independent evaluations or appraisals of the assets
or liabilities of BioShield or AHT, including, but not limited to, liabilities
arising from or connected with any pending or future litigation to which
BioShield or AHT is or may become a party. With respect to the financial
projections furnished to Gruntal or discussed by Gruntal with the managements of
BioShield and AHT, respectively, Gruntal assumed that they had been reasonably
prepared and reflect the best currently available estimates and judgements of
BioShield's and AHT's management as to the expected future results of
operations, synergies and financial condition of BioShield and AHT,
respectively, to which those analyses and forecasts relate, and Gruntal assumed
that the expected future results of operations, synergies and strategic benefits
will be realized as described by such management. The inability of BioShield and
AHT to realize the expected future results of operations, synergies and
strategic benefits could affect Gruntal's opinion and Gruntal expresses no view
as to whether such future results of operations, synergies and strategic
benefits will actually be realized. Gruntal also assumed that the transaction
will have the tax consequences described in the merger agreement and in
discussions with BioShield.

         In performing its analyses, Gruntal made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of BioShield. The analyses
performed by Gruntal are not necessarily indicative of actual values, which may
be significantly more or less favorable than suggested by these analyses. These
analyses were prepared solely as a part of Gruntal's analysis of the fairness,
from a financial point view, of the consideration to be paid to holders of AHT
common stock to BioShield's common stockholders and were provided to BioShield's
board in connection with the delivery of Gruntal's opinion. The analyses do not
purport to be appraisals or to reflect the prices at which AHT might actually be
sold. In addition, as described above, Gruntal's opinion was one of many factors
taken into consideration by BioShield's board in making its determination to
approve the merger. Consequently, the Gruntal analyses described above should
not be viewed as determinative of the opinion of BioShield's board or the view
of the management of BioShield with respect to the value of AHT common stock.

         Gruntal's opinion was necessarily based on economic, market and other
conditions as in effect on, and the information made available to it, as of June
30, 2000. It should be understood that subsequent developments including,
without limitation, any changes to the terms or conditions of the merger may
affect Gruntal's opinion and


                                       51
<PAGE>   64

that Gruntal does not have any obligation to update, revise, or reaffirm its
opinion. Gruntal also assumed that in the course of obtaining the necessary
regulatory or other consents or approvals, contractual or otherwise, for the
merger, no material restrictions, including any divestiture requirements or
amendments or modifications to the merger, will be imposed.

         The terms of the proposed merger were determined through negotiations
between AHT and BioShield and were approved by the BioShield board of directors.
Although Gruntal provided advice to BioShield during the course of these
negotiations, the decision to enter into the merger was solely that of the
BioShield board of directors.

         Gruntal's opinion did not address the merits of the underlying business
decision by BioShield to engage in the merger. Gruntal expressed no opinion as
to the prices at which BioShield or AHT shares would trade following the
announcement or, in the case of the BioShield shares, consummation of the
merger.

         The following is a summary of the material financial analyses performed
by Gruntal in arriving at its opinion.

         VALUATION OF AHT. In rendering its opinion, Gruntal, among other
things, performed four primary valuation analyses of AHT:

-        a relative contribution analysis, which analyzed the relative
         contributions of AHT and BioShield to the combined company for fiscal
         years ending June 30, 2000 and 2001;

-        a discounted cash flow analysis which consisted of adding the
         discounted present value of the projected future cash flows of AHT from
         January 1, 2000 to December 31, 2001 and the discounted present value
         of the terminal value of AHT, based on a multiple of earnings before
         interest, taxes, depreciation and amortization, or EBITDA, projected
         for the year ending December 31, 2001;

-        a comparable company analysis of AHT with certain publicly traded
         companies in the healthcare internet, or e-health, industry which
         consisted of reviewing and considering certain financial and market
         data for the e-health companies;

-        and a comparable merger and acquisition transactions analysis, which
         involved a comparison of the multiples paid and premiums to stock price
         paid in some merger and acquisition transactions involving companies in
         the e-health industry.

         RELATIVE CONTRIBUTION ANALYSIS. Gruntal analyzed the relative
contributions of AHT and BioShield to the combined company for the fiscal years
ending June 30, 2000 and 2001 attributable to the merger. AHT's financials for
fiscal years ending December 31, both actual and projected, were annualized to
coincide with BioShield's June 30 fiscal year end. Gruntal performed this
analysis to compare the 0.1458 exchange ratio in the proposed merger, based on
BioShield's closing stock price of $12.00 on June 30, 2000, with the implied
exchange ratios derived from comparing the contributions by each of AHT and
BioShield to the combined company during each of the pro forma fiscal years
ending June 30, 2000 through 2001. The analysis showed:

         Gruntal noted that the analysis resulted in implied exchange ratios

the relative contributions that the individual companies may actually make to
the combined company.

         AHT DISCOUNTED CASH FLOW ANALYSIS. Gruntal performed a discounted cash
flow analysis, based on the financial projections provided by AHT's management.
AHT's financial projections are highly dependent on the market acceptance of its
products and the efforts of corporate partners.

         An intrinsic value of AHT's equity was determined by the following
discounted cash flow method: calculating the present value of AHT's estimated
future cash flows from January 1, 2000 to December 31, 2001, and adding to such
amount the present value of AHT's terminal value obtained by capitalizing AHT's
projected EBITDA for the year ending December 31, 2001 at multiples of 15x, 18x,
20x and 22x. The range of these terminal value multiples is hypothetical and was
based on a range of multiples of EBITDA at which e-health companies are expected
to trade over the long term.

         Gruntal applied discount rates ranging from 20% to 40% to calculate the
present value of AHT's estimated future cash flows from January 1, 2000 to
December 31, 2001 and the terminal value based on a multiple of AHT's projected
EBITDA for 2001. This range of discount rates was derived using certain
assumptions as to the risk associated with the achievement of AHT's management
projections.

         The range of present values derived for AHT's equity by applying
discounted cash flow analysis based upon AHT's management projections was $73.7
million to $144.8 million, with an average value of $106.8 million, or, $5.67 to
$11.14 and $8.21 per share, respectively.

         AHT COMPARABLE COMPANY ANALYSIS. Gruntal analyzed nine e-health
companies to evaluate the market and aggregate values at which these companies
trade relative to their respective historical and projected financial
performance. The e-health companies in the AHT comparable company analysis
consisted of the following: Allscripts, Inc, Caredata.com, CareInsite, Inc.,
Claimsnet.com, Cybear, Inc., Healtheon/WebMD, MedicaLogic/Medscape, Inc.,
ProxyMed Inc., and the TriZetto Group, Inc. Gruntal analyzed, among other
things, the market values and certain financial criteria for the e-health
companies, including their revenue, EBITDA and earnings per share, in each case,
for the most recent twelve month period for which information was available and
on an estimated basis for 2000 and 2001. Such estimates for the e-health
companies were taken from I/B/E/S International Inc., a well-known aggregator of
financial data from publicly available research reports published by a variety
of investment firms and research analysts. The average values, excluding any
outliers, for market value of common equity on June 30, 2000 plus total
long-term debt and preferred stock less cash , or enterprise value, as a
multiple of each of the indicated statistics for the e-health companies were as
follows:

<TABLE>
                  <S>                                             <C>
                  Twelve months ended 3/31/2000 revenue           15.9 x
                  Projected 2000 revenue                           9.5 x
                  Projected 2001 revenue                           3.5 x
</TABLE>

         The average values, excluding any outliers, for market value of common
equity on June 30, 2000 as a multiple of net income and book value for the
following periods for the e-health companies were as follows:

<TABLE>
                  <S>                                              <C>
                  Projected 2001 net income                        5.7 x
                  Book value                                       3.7 x
</TABLE>

         Applying these results to AHT's last twelve months' results and AHT's
management projections yielded implied equity values for AHT ranging from $16.1
million to $96.9 million (or $1.25 to $7.52 per share), with an average of $53.6
million (or $4.16 per share), as compared to the $22.55 million in consideration
(or $1.75 per share) to be offered in BioShield common stock in the merger
(assuming that BioShield's common stock price is between $6.00 and $18.00 per
share).

         AHT COMPARABLE MERGER AND ACQUISITION TRANSACTIONS ANALYSIS. Gruntal
reviewed the consideration paid in certain merger and acquisition, or M&A,
transactions involving e-health companies. The transactions which Gruntal
reviewed consisted of the following acquisitions or pending acquisitions, in
descending chronological order: MedE America Inc. by Healtheon/WebMD;
MasterChart Inc. by Allscripts, Inc.; Medifor Inc. by Allscripts, Inc.; Medscape
Inc. by MedicaLogic Inc.; Envoy Corp. by Healtheon/WebMD; CareInsite Inc. by
Healtheon/WebMD; and Medical Manager Corp. by Healtheon/WebMD.

         Gruntal calculated premiums paid to price for each transaction based on
such acquired companies' respective trading prices one week and four weeks prior
to the announcement of the acquisitions. The high, low,


                                       53
<PAGE>   66

average and median premiums paid to the price one week before announcement for
the e-health M&A transactions were 59.7%, -34.1%, 17.4% and 21.9%, respectively.
The high, low, average and median premiums paid to the average price four weeks
before announcement for the e-health M&A transactions were 113.5%, -44.4%, 27.8%
and 21.1%, respectively.

         Applying the average premiums to AHT's June 30, 2000 valuation of
approximately $26 million derived values of AHT equity within the range of $30.5
million to $33.2 million, or $2.37 to $2.58 per share, with an average value of
$31.9 million, or $2.47 per share, as compared to the $22.55 million, or $1.75
per share, equity value in the merger.

         Gruntal also calculated multiples for each transaction based on the
transaction enterprise value to such acquired companies' pre-acquisition last
twelve months' results. The high, low, and average values of the enterprise
value as a multiple of each of the indicated statistics for the e-health M&A
transactions, excluding outliers, were as follows:

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

                  Twelve months revenue            7.6 x     64.9 x       34.9 x
                  Twelve months EBITDA            38.9 x     83.3 x       61.1 x
</TABLE>

         Applying the average multiples, excluding outliers, to AHT's last
twelve months' and projected results yielded a range in the implied value of
AHT's equity from $36.1 million to $346.0 million, or $2.80 to $26.85 per share,
with an average value of $191.0 million, or $14.82 per share, compared to the
$22.55 million, or $1.75 per share, equity value in the merger.

         OTHER ANALYSES. Gruntal reviewed current and historical market closing
prices and trading data of AHT's common stock over the past year. Gruntal noted
that over the past 52 weeks ended June 30, 2000, the high trading price was
$6.7188, the low trading price was $0.9375 and the average trading price was
$3.524. In addition, Gruntal reviewed current and historical market closing
prices and trading data of BioShield's common stock over the past year. Gruntal
noted that over the past 52 weeks ended June 30, 2000, the high trading price
was $36.50, the low trading price was $7.3125 and the average trading price was
$13.978.

         Gruntal reviewed the daily closing prices of AHT's common stock and
BioShield's common stock to determine a hypothetical exchange ratio based upon
the market prices of AHT common stock and BioShield common stock. Gruntal
analyzed the implied exchange ratio between AHT's common stock and BioShield's
common stock for the most recent trading date prior to the delivery of the
fairness opinion, the one, five and ten trading days prior to such date and the
average for the last week, two weeks, four weeks and eight weeks. Gruntal
performed this analysis to compare the 0.1458 exchange ratio, based on
BioShield's closing stock price on June 30, 2000 of $12.00 per share, pursuant
to the BioShield/AHT merger agreement with the exchange ratios between AHT's
common stock and BioShield's common stock prevailing in the open market. The
analysis showed:

                  The exchange ratio analysis resulted in implied exchange
ratios which ranged from 0.1036 to 0.1862 for the time periods indicated above,
as compared to the exchange ratio in the merger of 0.1458, based on BioShield's
closing stock price of $12.00 on June 30, 2000.

         CONCLUSION. The preparation of a fairness opinion is a complex process
and is not necessarily susceptible to a partial analysis or summary description.
The preceding summary is not a complete description of the analyses


                                       54
<PAGE>   67

performed by Gruntal. In arriving at its opinion, Gruntal considered the results
of all of its analyses as a whole and did not attribute any particular weight to
any particular analysis or factor considered by it, but rather made qualitative
judgments as to the significance and relevance of each analysis and factor.
Furthermore, selecting any portion of Gruntal's analyses, without considering
all analyses, would create an incomplete view of the process underlying
Gruntal's opinion, and could result in an incorrect conclusion. In addition,
Gruntal may have deemed various assumptions more or less probable than other
assumptions, so that the ranges of valuations resulting for any particular
analysis described above should not be taken to be Gruntal's view of the actual
value of AHT common stock.

         No transaction utilized in the comparable transaction analysis is
identical to the merger, and no company utilized in the comparable companies
analysis is identical to AHT. In evaluating the precedent transactions and the
selected comparable companies, Gruntal made judgments and assumptions with
regard to industry performance, general business, economic, market and financial
conditions and other matters, many of which are beyond the control of BioShield,
such as the impact of competition on the business of BioShield and the industry
generally, industry growth and the absence of any adverse material change in the
financial condition and prospects of AHT or the industry or in the financial
markets in general.

         BioShield's board retained Gruntal based upon Gruntal's experience and
expertise. Gruntal is a nationally recognized investment banking and financial
advisory firm. Gruntal, as part of its investment banking business, is
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings,
distributions of listed and unlisted securities, private placements and
financial valuations for corporate purposes. In addition, in the ordinary course
of its business, Gruntal may actively trade BioShield common stock for Gruntal's
account and for the accounts of customers, and accordingly, may at any time hold
a long or short position in such security.

         Pursuant to an engagement letter with Gruntal, BioShield has agreed to
pay Gruntal a customary fee and other compensation in connection with the
investment banking and financial advisory services provided by Gruntal in
connection with the merger and the delivery of the fairness opinion. BioShield
also agreed to reimburse Gruntal for its reasonable out-of-pocket expenses and
to indemnify Gruntal against certain liabilities, including liabilities under
the federal securities laws or relating to or arising out of Gruntal's
engagement as financial advisor.

         Gruntal has performed investment banking and financial advisory
services for both BioShield and AHT in the past and has been compensated for
those services. In addition, in the future Gruntal may provide investment
banking and financial advisory services to BioShield.



OPINION OF AHT'S FINANCIAL ADVISOR

         AHT engaged Chase H&Q to act as a financial advisor to AHT in
connection with the proposed merger. The AHT board of directors selected Chase
H&Q to act as a financial advisor based on Chase H&Q's qualifications, expertise
and reputation, as well as Chase H&Q's historic investment banking relationship
and familiarity with AHT. Chase H&Q delivered its oral opinion on June 29, 2000,
subsequently confirmed in writing on June 30, 2000, to the AHT board of
directors that, as of that date, based upon and subject to the assumptions made,
matters considered and limits of the review undertaken by Chase H&Q, the
consideration to be received by the holders of AHT common stock was fair from a
financial point of view.

         The full text of the opinion delivered by Chase H&Q to the AHT board of
directors, dated June 30, 2000, which sets forth the assumptions made, general
procedures followed, matters considered and limitations on the scope of review
undertaken by Chase H&Q in rendering its opinion, is attached as Appendix C to
this joint proxy statement/prospectus and is incorporated herein by reference.
The Chase H&Q opinion does not constitute a recommendation to any AHT
stockholder as to how the AHT stockholders should vote on the merger agreement.
The summary of the Chase H&Q opinion set forth below is qualified in its
entirety by reference to the full text of the opinion attached as Appendix B.
AHT stockholders are urged to read the opinion carefully in its entirety.

         In reviewing the proposed transactions, and in arriving at its opinion,
Chase H&Q, among other things:

         -        reviewed the publicly available financial statements of
                  BioShield for recent years and interim periods to date and
                  certain other relevant financial and operating data of


                                       55
<PAGE>   68

                  BioShield (including its capital structure) made available to
                  Chase H&Q from published sources and from the internal records
                  of BioShield;

         -        reviewed certain internal financial and operating information,
                  including certain projections, relating to BioShield prepared
                  by the management of BioShield;

         -        discussed the business, financial condition and prospects of
                  BioShield with certain members of its senior management;

         -        reviewed the publicly available financial statements of AHT
                  for recent years and interim periods to date and certain other
                  relevant financial and operating data of AHT made available to
                  Chase H&Q from published sources and from the internal records
                  of AHT;

         -        reviewed certain internal financial and operating information,
                  including certain projections, relating to AHT prepared by the
                  senior management of AHT;

         -        discussed the business, financial condition and prospects of
                  AHT with certain members of senior management;

         -        reviewed the recent reported prices and trading activity for
                  the common stocks of BioShield and AHT and compared that
                  information and certain financial information for BioShield
                  and AHT with similar information for certain other companies
                  engaged in businesses we consider comparable;

         -        reviewed the financial terms, to the extent publicly
                  available, of certain merger and acquisition transactions; and

         -        reviewed the merger agreement.

         Chase H&Q did not assume responsibility for independent verification
of, and did not independently verify, any of the information concerning AHT or
BioShield considered in connection with its review of the proposed transactions,
including without limitation any financial information, forecasts or
projections, considered in connection with the rendering of its opinion.
Accordingly, for purposes of its opinion, Chase H&Q assumed and relied upon the
accuracy and completeness of all this information. In connection with its
opinion, Chase H&Q did not prepare or obtain any independent valuation or
appraisal of any of the assets or liabilities of AHT or BioShield, and it did
not conduct a physical inspection of the properties and facilities of AHT or
BioShield. With respect to the financial forecasts and projections used in its
analysis, Chase H&Q assumed that they reflected the best currently available
estimates and judgments of the expected future financial performance of AHT and
BioShield, and Chase H&Q expressed no view as to the reasonableness of these
forecasts and projections or the assumptions on which these forecasts or
projections were based. For the purposes of its opinion, Chase H&Q also assumed
that neither AHT nor BioShield was a party to any pending transactions,
including without limitation external recapitalizations or material merger or
acquisition discussions, other than the proposed merger and transactions in the
ordinary course of conducting their respective businesses, except that BioShield
management described to Chase H&Q a potential acquisition that may be
consummated in the near term, and Chase H&Q assumed, with the consent of AHT,
that this transaction would be completed on reasonable commercial terms. AHT
advised Chase H&Q, and for purposes of its opinion Chase H&Q assumed, that the
proposed merger would be tax-free to each of AHT and BioShield and would be
treated as a purchase for financial accounting purposes.

         In performing its analyses, Chase H&Q used published Wall Street
estimates of fiscal year 2000 and 2001 financial performance of BioShield and
made numerous assumptions with respect to industry performance, general business
and economic conditions and other matters, many of which are beyond the control
of AHT, BioShield or Chase H&Q. The analyses performed by Chase H&Q and
summarized below are not necessarily indicative of actual values or actual
future results, which may be significantly more or less favorable than suggested
by these analyses. Because these analyses are inherently subject to uncertainty,
being based upon numerous factors or events beyond the control of AHT, BioShield
or their respective advisors, neither AHT, Chase H&Q nor any other person
assumes responsibility if future results or actual values are materially
different from the results of analyses based on


                                       56
<PAGE>   69

forecasts or assumptions. Additionally, analyses relating to the values of
businesses do not purport to be appraisals or to reflect the prices at which
businesses or securities actually may be acquired or bought or sold.

         Chase H&Q's opinion is necessarily based upon market, economic,
financial and other conditions as they existed and can be evaluated as of the
date of the opinion and any subsequent change in these conditions would require
a reevaluation of that opinion. Although subsequent developments may affect its
opinion, Chase H&Q has assumed no obligation to update, revise or reaffirm it.

         The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to summary description. The summary of Chase H&Q's
analyses set forth below summarizes the material analyses presented to the AHT
board of directors but is not a complete description of the presentation by
Chase H&Q to the AHT board of directors or the analysis performed by Chase H&Q
in connection with preparing its opinion. In arriving at its opinion, Chase H&Q
did not attribute any particular weight to any analyses or factors considered by
it, but rather made subjective, qualitative judgments as to the significance and
relevance of each analysis and factor. Accordingly, Chase H&Q believes that its
analyses and the summary set forth below must be considered as a whole and that
selecting portions of its analyses, without considering all analyses, or of the
following summary, without considering all factors and analyses, could create an
incomplete view of the processes underlying the analyses set forth in the Chase
H&Q presentation to the AHT board of directors and Chase H&Q's opinion.

         The terms of the proposed merger were determined through negotiations
between AHT and BioShield and were approved by the AHT board of directors.
Although Chase H&Q provided advice to AHT during the course of these
negotiations, the decision to enter into the merger was solely that of the AHT
board of directors. As described above, the opinion of Chase H&Q and its
presentation to the AHT board of directors were only one of a number of factors
taken into consideration by the AHT board of directors in making its
determination to approve the proposed merger.

         The following is a brief summary of the material financial analyses
performed by Chase H&Q in connection with providing its opinion to the AHT board
of directors on June 30, 2000. The summary includes information presented in
tabular format. You should read this table together with the text of the related
summary, because the table alone is not a complete description of the financial
analysis.

         PREMIUM ANALYSIS. Chase H&Q calculated the implied premium over the
closing price of AHT common stock as of June 29, 2000 of the consideration to be
paid in the proposed merger, assuming the value of BioShield common stock was
its closing price on June 29, 2000 of $11.75.

         CAPITALIZATION ANALYSIS. Chase H&Q determined that AHT possessed
approximately $4.3 million in available cash as of March 31, 2000. Based on
estimates of management of AHT, Chase H&Q determined that AHT would possess
approximately $2.0 million in available cash as of June 30, 2000. Chase H&Q also
noted that AHT's operations used an average of approximately $0.8 million per
month for the six months ended June 30, 2000, and that management of AHT had
contacted several financing sources regarding an investment in AHT, but none of
these contacts proposed an investment in AHT, and, as of June 29, 2000, there
were no pending discussions.

         STOCK PRICE AND FINANCIAL ANALYSIS. Chase H&Q reviewed the relative
common stock price performance of AHT and BioShield from January 3, 2000 to June
29, 2000 and compared this performance to the Nasdaq Composite Index and an
index of selected publicly traded e-health companies. Chase H&Q observed that
the common stock price of AHT had decreased approximately 50.0% during the
period reviewed, while the common stock price of BioShield had increased
approximately 11.6% during the same period. Chase H&Q also noted that


                                       57
<PAGE>   70

the Nasdaq Composite Index and the index of selected e-health companies had
decreased approximately 4.6% and approximately 35.2% during the period reviewed.

         Chase H&Q also compared publicly available analyst forecasts of
BioShield's fiscal year 2001 revenues and gross profit and compared these
forecasts with the estimates of BioShield's management provided to Chase H&Q.
Chase H&Q noted that management estimates of revenue and gross profit were
approximately 16% and 29% lower than the publicly available analyst forecasts.

         PRO FORMA CONTRIBUTION ANALYSIS. Chase H&Q determined the implied pro
forma ownership of the combined company, assuming an exchange ratio in the
merger of 0.14894 shares of BioShield common stock per share of AHT common
stock, based on the closing price of BioShield common stock on June 29, 2000 of
$11.75. Chase H&Q then computed the portion of the combined company's pro forma
fiscal year 2000 revenues contributed by AHT, based on estimates provided by the
companies' managements. Chase H&Q noted that shareholders of AHT would own 16.5%
of the outstanding common stock of the combined company on a pro forma basis,
and that AHT would account for 21.6% of the combined company's estimated pro
forma fiscal year 2001 revenues.

         The foregoing description of Chase H&Q's opinion is qualified in its
entirety by reference to the full text of the opinion which is attached as
Appendix B to this joint proxy statement / prospectus.

         Chase H&Q, as part of its investment banking services, is regularly
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, strategic transactions, corporate restructurings,
negotiated underwritings, secondary distributions of listed and unlisted
securities, private placements and valuations for corporate and other purposes.
Chase H&Q has previously provided investment banking and other financial
advisory services to AHT and has received fees for rendering these services. In
the ordinary course of business, Chase H&Q may trade in the equity and
derivative securities of AHT and BioShield for its own account or for the
accounts of its customers and, accordingly, may at any time hold a long or short
position in these securities. Chase H&Q may in the future provide investment
banking or other financial advisory services to AHT or BioShield.

         Pursuant to an engagement letter with Chase H&Q, AHT became obligated
to pay Chase H&Q a fee of $250,000 upon the delivery of the fairness opinion and
an additional fee of $375,000 upon consummation of the merger. AHT also agreed
to reimburse Chase H&Q for its reasonable out-of-pocket expenses and to
indemnify Chase H&Q against certain liabilities, including liabilities under the
federal securities laws or relating to or arising out of Chase H&Q's engagement
as financial advisor.


INTERESTS OF AHT'S DIRECTORS, OFFICERS AND AFFILIATES IN THE MERGER

         When considering the recommendation of AHT's board of directors, you
should be aware that some of AHT's directors and officers have interests in the
merger that are different from, or are in addition to, your interests. Please
see the section entitled "Interests of AHT's directors, officers and affiliates
in the merger" on page __ of this joint proxy statement/prospectus. The AHT
board of directors was aware of these potential conflicts and considered them.

         As of July 21, 2000, AHT's executive officers and directors held a
total of 856,441 shares of AHT common stock, including currently exercisable
options, or approximately 7.7% of the total outstanding shares of AHT common
stock. In addition, AHT's executive officers and directors held options to
purchase a total of 861,558 shares of AHT common stock, at the weighted average
exercise price of $2.43 per share. 402,341 of those shares were held pursuant to
unvested options.

         Jonathan Edelson, M.D., Robert J. Alger, Jeffrey M. Sauerhoff and Eddy
W. Friedfeld have employment agreements that provide that if any of them are
terminated without cause after the merger, all of their outstanding options will
immediately vest and they will receive severance payments. In addition, each of
them will receive a bonus upon the completion of the merger. In connection with
signing of the merger agreement, the employment contracts of Jonathan Edelson,
Jeffrey Sauerhoff and Eddy Friedfeld were amended to provide that 60% of the
amount each will be entitled to receive under their employment agreement if he
is terminated without cause after the merger will be paid in cash and the
remaining 40% will be paid in BioShield common stock. Additionally, Jonathan
Edelson will provide consulting services to BioShield for one year if he is
terminated without cause.


                                       58
<PAGE>   71

Additionally, Jonathan Edelson and Robert Alger have discussed their potential
continued employment with BioShield or a subsidiary of BioShield after
completion of the merger.

         Under the merger agreement, BioShield has agreed to honor any
indemnification provisions for AHT's directors and officers in AHT's articles of
incorporation and by-laws. In addition, BioShield has agreed to maintain AHT's
directors' and officers' indemnify insurance for four years after the completion
of the merger, provided that BioShield is not required to pay more than
approximately $95,000 per year of the annual premium for AHT's insurance.

         As a result of these interests, these directors and officers of AHT
could be more likely to vote to adopt and approve the merger agreement and the
merger than if they did not hold these interests. AHT's stockholders should
consider whether these interests may have influenced these directors and
officers to support or recommend the merger.


STRUCTURE OF THE MERGER AND CONVERSION OF STOCK AND OPTIONS

         AHT Acquisition Corp. is a newly formed Delaware corporation, formed
specifically for the merger described in this joint proxy statement/prospectus.
As provided in the merger agreement, AHT will merge with and into AHT
Acquisition Corp., with AHT being the surviving corporation. Upon the completion
of the merger, AHT will become a wholly owned subsidiary of BioShield, and AHT
stockholders will become stockholders of BioShield as described in the following
paragraphs.


MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS OF THE MERGER

         The following is a summary of the material anticipated U.S. federal
income tax consequences of the merger. This summary is:

         -        limited to U.S. holders, who are United States persons who
                  hold their AHT common stock as a "capital asset" and whose
                  "functional currency" is the U.S. dollar;

         -        based on the Internal Revenue Code of 1986, treasury
                  regulations, administrative rulings and court decisions, all
                  as in effect as of the date of this document and all of which
                  are subject to change at any time, possibly with retroactive
                  effect, or different interpretation;

         -        not a complete description of all of the considerations that
                  may be relevant to a decision whether to adopt and approve the
                  merger and, in particular, may not address U.S. federal income
                  tax considerations applicable to stockholders subject to
                  special treatment under U.S. federal income tax law, which
                  would include, for example:

         -        non-U.S. persons;

         -        financial institutions;

         -        regulated investment companies;

         -        real estate investment trusts;

         -        real estate mortgage investment conduits;

         -        financial asset securitization investment trusts;

         -        dealers in securities or currencies;

         -        traders in securities that elect to mark to market;

         -        insurance companies, tax-exempt entities;

         -        holders owning AHT common stock as part of a hedge, straddle,
                  short sale or conversion transaction; and

         -        holders who acquired their AHT common stock as a result of the
                  exercise of an employee option or otherwise as compensation.

         In addition, no information is provided in this document about the tax
consequences of the merger under applicable foreign, state or local laws. WE
URGE YOU TO CONSULT WITH YOUR OWN TAX ADVISORS REGARDING THE FEDERAL INCOME AND
OTHER TAX CONSEQUENCES OF THE MERGER TO YOU, INCLUDING THE EFFECTS OF STATE,
LOCAL AND FOREIGN TAX LAWS.

         United States person means:

         -        a citizen or resident of the United States;

         -        a corporation created or organized in or under the laws of the
                  United States or any state within the U.S.;

         -        an estate whose income is subject to United States federal
                  income tax regardless of its source; or

         -        a trust if a United States court can exercise primary
                  supervision over the trust's administration and one or more
                  United States persons are authorized to control all
                  substantial decisions of the trust or a trust that has elected
                  to be taxed as a domestic trust for United States federal
                  income tax purposes.


         We have not requested and do not plan to request any rulings from the
IRS concerning the tax treatment of the merger. The statements in this document
and the opinions of counsel referred to in this document aren't binding on the
IRS or a court. You should be aware that the IRS or a court might disagree with
our conclusion.

         This section, as it relates to matters of United States federal income
tax law constitutes the opinion of D'Agostino, Levine & Landesman, L.L.P., tax
counsel to BioShield. This opinion is based upon a number of facts, assumptions
and representations of BioShield, AHT and AHT Acquisition Corp. Based upon the
above, the merger will constitute a "reorganization" which is granted special
treatment under the Internal Revenue Code. As a "reorganization," the merger
will have the following principal United States federal income tax consequences:

         -        no gain or loss will be recognized by BioShield, AHT
                  Acquisition Corp. or AHT by reason of the merger;

         -        no gain or loss will be recognized by U.S. holders of AHT
                  common stock who exchange their AHT common stock for BioShield
                  common stock in accordance with the merger, except with
                  respect to any cash received instead of a fractional share of
                  BioShield common stock (as discussed below);

         -        the aggregate tax basis of the BioShield common stock received
                  in the merger by each U.S. holder of AHT common stock will be
                  the same as the aggregate tax basis of the AHT common stock
                  surrendered in the exchange, reduced by any amount of tax
                  basis allocable to a fractional share interest in BioShield
                  common stock for which cash is received; and

         -        the holding period of BioShield common stock received in the
                  merger will include the holding period for the AHT stock
                  surrendered in the exchange.


         Cash received by a U.S. holder of AHT common stock in exchange for a
fractional share of BioShield common stock will be treated as received in place
of the fractional share. These types of holders generally will recognize capital
gain or loss measured by the difference between the amount of cash received and
the portion of the tax basis of the holder's AHT common stock allocable to the
fractional share interest. In addition, for a U.S. holder of AHT common stock
who exercises appraisal rights and receives solely cash in exchange for that
holder's AHT common stock the merger will be a taxable event. In this case
capital gain or loss will be recognized measured by the difference between the
amount of cash received, and the tax basis of that holder's AHT common stock
surrendered.

         Any capital gain or loss, in either case, will be long-term capital
gain or loss if that holder has held its AHT common stock for more than one
year.

         BACKUP WITHHOLDING. Unless a holder of AHT common stock complies with
reporting and/or certification procedures or establishes that it is exempt, cash
payments in exchange for that holder's AHT common stock in the merger may be
subject to "backup withholding" at a rate of 31% for federal income tax
purposes. Any amounts


                                       60
<PAGE>   73

withheld under the backup withholding rules may be allowed as a refund or a
credit against the holder's federal income tax liability, provided the required
information is furnished to the IRS.

THE ABOVE SUMMARY IS NOT INTENDED TO CONSTITUTE A COMPLETE ANALYSIS OF ALL OF
THE U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER. THIS SUMMARY MAY NOT
APPLY TO A PARTICULAR STOCKHOLDER IN LIGHT OF THE STOCKHOLDER'S PARTICULAR
CIRCUMSTANCES.


ACCOUNTING TREATMENT OF THE MERGER

         BioShield intends to account for the merger as a purchase of AHT by AHT
Acquisition Corp. for financial reporting and accounting purposes, in accordance
with generally accepted accounting principles.


RESTRICTIONS ON SALES OF SHARES BY AFFILIATES

         The shares of BioShield common stock to be issued in the merger will be
registered under the Securities Act. These shares will be freely transferable
under the Securities Act, except for shares of BioShield common stock issued to
any person who is an affiliate of BioShield or AHT. Persons who may be deemed to
be affiliates include individuals or entities that control, or are controlled
by, or are under the common control of BioShield or AHT, and may include their
respective directors and officers, as well as their principal stockholders.

         Affiliates may not sell their shares of BioShield common stock acquired
in the merger except pursuant to (1) an effective registration statement under
the Securities Act covering the resale of those shares, (2) an exemption under
paragraph (d) of Rule 145 under the Securities Act or (3) any other applicable
exemption under the Securities Act.

         This joint proxy statement/prospectus can not be used in connection
with resales of BioShield common stock received in the merger by an affiliate of
BioShield or AHT.


MANAGEMENT AND OPERATIONS OF BIOSHIELD FOLLOWING THE MERGER

         Following the merger, BioShield will continue the operations of AHT as
its wholly owned subsidiary. As of the date of this joint proxy
statement/prospectus, BioShield intends to examine the operations of AHT to
identify opportunities to reduce overhead by elimination of any functions that
would be duplicative with the operations of eMD, but has no other specific
material plans. The AHT stockholders will become stockholders of BioShield, and
their rights as stockholders will be governed by BioShield's articles of
incorporation, by-laws and the laws of the State of Delaware. For a description
of the differences between the rights of BioShield common stockholders and AHT
common stockholders, please see "Comparison of rights of AHT stockholders and
BioShield stockholders" beginning on page __ of this joint proxy
statement/prospectus.


APPRAISAL RIGHTS

         Appraisal rights under Delaware law are available to AHT stockholders
in connection with the merger. To claim appraisal rights, an AHT stockholder
must comply with the following requirements:

         -        Before the stockholder vote is taken, you must deliver a
                  written demand for the appraisal of your shares.

         -        You must continuously hold your AHT shares through the
                  completion of the merger.

         -        You must not vote your shares in favor of the merger either by
                  proxy or at the AHT stockholders' meeting.

         -        If you properly notified AHT of your intent to demand
                  appraisal rights, AHT will send you written notice within ten
                  (10) days after the completion of the merger that you have
                  properly asserted your appraisal rights.


                                       61
<PAGE>   74

         -        Within one hundred twenty (120) days after the completion of
                  the merger, you must file a petition in the Court of Chancery
                  of Delaware demanding that the court determine the fair value
                  of your shares.

         If you do not comply with the requirements outlined above, you will not
be entitled to receive payment for your shares under the appraisal rights
provisions of Delaware law. YOUR APPRAISAL RIGHTS ARE SET OUT IN THEIR ENTIRETY
IN SECTION 262 OF THE GENERAL CORPORATION LAW OF DELAWARE, WHICH IS ATTACHED TO
THIS JOINT PROXY STATEMENT/PROSPECTUS AS APPENDIX Q.

                              THE MERGER AGREEMENT

         The following summary describes certain aspects of the proposed merger,
including the material provisions of the merger agreement. The following
description of the merger does not purport to be complete and is qualified in
its entirety by reference to the merger agreement, which is attached as Appendix
A to this joint proxy statement/prospectus and is incorporated herein by
reference. All holders of BioShield common stock and AHT common stock are urged
to carefully read the merger agreement and the other documents incorporated by
reference in the merger agreement.

GENERAL; MERGER CONSIDERATION

         The merger agreement provides for a business combination between AHT
and AHT Acquisition Corp., a wholly owned subsidiary of BioShield, with AHT as
the surviving corporation. Subject to the satisfaction of the conditions in the
merger agreement, the merger will be completed and the holders of AHT common
stock will be issued shares of BioShield common stock. The acquisition will be
accounted for using the purchase method of accounting and it will be considered
a "reorganization" as that term is understood in the Internal Revenue Code for
federal income tax purposes. In the merger, each outstanding share of AHT common
stock will be converted into and become exchangeable for a number of shares of
BioShield common stock equal to the exchange ratio, as we explain in the next
section. Each share of BioShield common stock will remain outstanding following
the merger.

CLOSING OF THE MERGER

         The closing of the merger will take place at 10:00 a.m. on a date which
is no later than the second business day after the conditions to the merger
described in the merger agreement have been satisfied or waived. Alternately,
the closing of the merger may take place at any other time as we agree in
writing. The closing is expected to take place shortly after the adoption and
approval of the merger by AHT stockholders and approval of the issuance of
BioShield common stock in connection with the merger by BioShield stockholders.

EFFECTIVE TIME OF THE MERGER

         As soon as possible after the closing of the merger, AHT and BioShield
will cause a certificate of merger to be executed, acknowledged and filed with
the Secretary of State of Delaware as required under Delaware law. The merger
will become effective when the certificate of merger is properly filed with the
Delaware Secretary of State, or at another time agreed to by BioShield and AHT
and specified in the certificate of merger. We anticipate that the filing of the
certificate of merger will be made simultaneously with, or as soon as
practicable after, the closing of the merger.

CONVERSION OF SHARES OF AHT COMMON STOCK INTO SHARES OF BIOSHIELD COMMON STOCK

         At the completion of the merger, and without any action on the part of
the AHT common stockholders, each issued and outstanding share of AHT common
stock will become exchangeable for $1.75 worth of BioShield common stock. In the
exchange, the AHT common stockholders will receive cash instead of any
fractional shares of BioShield common stock into which the shares of AHT common
stock have been converted. In addition, AHT common stockholders will receive the
right to receive cash for any distribution or dividend regarding the BioShield
common stock with a record date that is at or after the effective time of the
merger, in each case without interest.

THE EXCHANGE RATIO

         The exchange ratio of this stock-for-stock merger is subject to collar
protection and will be determined based on the following:


                                       63
<PAGE>   76

         -        The number of shares of BioShield common stock for each share
                  of AHT common stock will fluctuate within the collar so that
                  AHT common stockholders will receive $1.75 worth of BioShield
                  common stock if the average closing trading price of BioShield
                  common stock, as determined in accordance with the merger
                  agreement, is between $6.00 and $18.00 per share.

         -        The exchange ratio outside of the collar will be fixed. AHT
                  common stockholders will receive .29167 shares of BioShield
                  common stock for each share of AHT common stock if the
                  BioShield stock price is $6.00 or less and .09722 shares of
                  BioShield common stock if the BioShield stock price is $18.00
                  or above.


         The chart below sets forth a range of average closing trading prices
for BioShield common stock, the value of BioShield common stock to be received
by AHT stockholders for each share of AHT common stock and the corresponding
exchange ratio. AHT stockholders may call Arthur Dague at (914) 524-4783 for the
exact number of shares of BioShield common stock to be issued to them based on
the most recent average closing trading price of AHT common stock.

</TABLE>

         If at any time during the period between June 30, 2000, the date of the
merger agreement, and the date that the merger is completed there is a change in
the number of shares of BioShield common stock issued and outstanding due to a
stock split, stock dividend, recapitalization, subdivision, reclassification,
combination, merger, exchange of shares or other similar transaction, the merger
consideration received by AHT stockholders will be proportionately adjusted to
reflect that stock split, stock dividend, recapitalization, subdivision,
reclassification, combination, merger, exchange of shares or other similar
transaction.

         BioShield will not issue any fractional shares of BioShield common
stock in the merger. Instead, each of you who is entitled to receive a fraction
of a share of BioShield common stock will receive cash, without interest, in an
amount equal to your proportionate interest in the net proceeds from the sale of
all of the aggregate fractional shares of BioShield common stock.

EXCHANGE OF CERTIFICATES FOR SHARES OF AHT COMMON STOCK

         Promptly after the effective time of the merger, BioShield's exchange
agent will mail transmittal forms and exchange instructions to each holder of
record of AHT common stock. Each holder of AHT common stock certificates will be
able to surrender stock certificates to BioShield's exchange agent. Each
certificate surrendered to the exchange agent together with an executed letter
of transmittal will be cancelled, and each holder will receive in exchange
certificates representing the number of whole shares of BioShield common stock
to which the holder is entitled, any cash which may be payable instead of a
fractional share of BioShield common stock and any dividends


                                       64
<PAGE>   77

or other distributions on BioShield common stock with a record date at or after
the effective time of the merger. No interest will be paid or accrued on any
amount payable upon surrender of the AHT common stock certificates.

         HOLDERS OF AHT COMMON STOCK SHOULD NOT SEND THEIR COMMON STOCK
CERTIFICATES TO THE EXCHANGE AGENT UNTIL THEY RECEIVE TRANSMITTAL MATERIALS FROM
THE EXCHANGE AGENT. HOLDERS OF BIOSHIELD COMMON STOCK WILL NOT EXCHANGE THEIR
CERTIFICATES REPRESENTING SHARES OF BIOSHIELD COMMON STOCK.

DIVIDENDS AND DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED AHT COMMON STOCK
CERTIFICATES

         All shares of BioShield common stock to be issued in the merger will be
treated as outstanding as of the effective time of the merger. Whenever a
dividend or other distribution is declared by BioShield regarding the BioShield
common stock, and the record date is at or after the effective time of the
merger, that declaration will include dividends or other distributions on all
shares of BioShield common stock which may be issued under the merger agreement.
No dividends or other distributions on the BioShield common stock will be paid
to any holder of unsurrendered AHT common stock certificates until the
stockholder surrenders the AHT common stock certificates for exchange.

STOCK OPTIONS AND OTHER AWARDS

         At the effective time of the merger, each outstanding option to
purchase AHT common stock will constitute an option to acquire, on the same
terms and conditions as were applicable under that option, the same number of
shares of BioShield common stock as the holder of that option would have been
entitled to receive if that holder exercised its option in full immediately
prior to the effective time of the merger. The price per share is equal to the
aggregate exercise price for the AHT common stock that the holder was entitled
to purchase under that option divided by the number of full shares of BioShield
common stock purchasable under that option.

         AHT will make all necessary arrangements concerning its stock plans to
permit the assumption by BioShield of any unexercised options. BioShield will
take all corporate action necessary to reserve shares of BioShield common stock
for issuance upon exercise of options assumed by it. As soon as practicable
after the effective time, BioShield will file a registration statement regarding
the BioShield common stock subject to the options.

         As soon as practicable after the consummation of the merger, BioShield
will deliver to the holders of options to acquire BioShield common stock
appropriate notices setting forth the holders' rights pursuant to each stock
plan.

CORPORATE GOVERNANCE AFTER THE EFFECTIVE TIME OF THE MERGER

         The AHT certificate of incorporation and by-laws in effect immediately
prior to the effective time of the merger will continue to be the certificate of
incorporation and by-laws of AHT as the surviving corporation after the
effective time of the merger. However, Article IV of the AHT certificate of
incorporation will be amended to so that AHT will have the authority to issue
only 1,000 shares of common stock, par value $0.0001 per share.

         The officers and directors of AHT Acquisition Corp. immediately prior
to the effective time of the merger will be the initial directors and officers
of AHT as the surviving corporation until these officers and directors either
resign, are removed or their successors are properly elected and qualified.

                  or benefits except as may be required by applicable law; and

         -        it will not authorize any of or agree to take any of the
                  actions just listed.

ACCESS TO INFORMATION

         AHT has agreed to provide to BioShield upon request, access to all of
its properties, books, contracts, commitments, personnel and records. AHT has
also agreed to provide BioShield with copies of each report, schedule,
registration statement and other document filed by it under the securities laws,
a copy of each material tax return, report and information statement filed by it
and all other information concerning its business, assets, properties and
personnel as BioShield may reasonably request.

NO SOLICITATION OF ACQUISITION PROPOSALS

         AHT has agreed that prior to the effective time of the merger or the
termination of the merger agreement, it will not, directly or indirectly,
through advisors, agents or other intermediaries, and it will not permit or
cause its and its subsidiaries' respective officers, directors, advisors,
representatives and other agents to, directly or indirectly:

         -        solicit, initiate or knowingly encourage, or otherwise
                  facilitate, any inquiries or the making of any proposal that
                  constitutes, or may reasonably be expected to lead to, any
                  acquisition proposal;

         -        engage in substantive discussions or negotiations with, or
                  disclose or provide any non-public information about AHT or
                  its subsidiaries or give access to the properties, books or
                  records of AHT or its subsidiaries to, any person that has
                  made a proposal to acquire AHT or with or to any person in
                  contemplation of a proposal to acquire AHT; or

         -        enter into any agreement or agreement in principle providing
                  for or relating to a proposal to acquire AHT.

         However, if a person submits an unsolicited written acquisition
proposal and AHT's board of directors believes in good faith, after consulting
with their financial advisor, that the unsolicited proposal is superior to
BioShield's proposal and, after consulting with their legal counsel, that
engaging in negotiations or providing information about AHT is required to
satisfy its fiduciary duties, then AHT may:

         -        provide information in response to an unsolicited written
                  proposal to acquire AHT if AHT receives from the requesting
                  person an executed confidentiality agreement;

         -        engage in negotiations and discussions with the person who
                  submitted the written proposal; and

         -        three days after providing written notice to BioShield of
                  AHT's intention to approve or recommend the acquisition
                  proposal or terminate the merger agreement, the AHT board of
                  directors may recommend the new acquisition proposal to you if
                  they determine in good faith that they are required to do so
                  in order to comply with their fiduciary duties.

         The merger agreement also requires that AHT:

         -        promptly notify BioShield of any request for information with
                  respect to any acquisition proposal or any inquiry that is
                  reasonably likely to lead to an acquisition proposal; and

         -        provide written notice to BioShield that AHT intends to
                  approve or recommend any acquisition proposal, which specifies
                  the material terms and conditions of the proposal and
                  identifies the person who made the proposal.

law.

         For at least four years from the effective time of the merger,
BioShield has agreed to maintain AHT's current policies of directors' and
officers' liability insurance. BioShield will maintain these policies on terms
and conditions substantially similar to AHT's existing directors' and officers'
insurance so long as the annual premium for this insurance is not more than 125%
of the amount AHT paid for this directors' and officers' insurance in its last

honor in accordance with their terms.

by BioShield employee benefits in the aggregate no less favorable than those
benefits provided to BioShield's similarly situated employees. BioShield is

subsidiaries. BioShield will credit any retained employees with their prior
service for purpose of receiving benefits under BioShield's benefit plans.

AHT under the related Securities Purchase Agreement by and between AHT and
Cybear, Inc., dated March 27, 2000, and the related agreements and documents,
including the warrants to purchase shares of AHT common stock, entered into in

                         INFORMATION REGARDING BIOSHIELD

         BioShield Technologies, Inc. is a Georgia corporation organized in
June, 1995 and has, since inception, been primarily engaged in research and
development, patent filings, procurement of regulatory approvals and related
activities geared towards the sale of its retail, industrial and institutional
products. Most of the products which have been produced and marketed are
cleaning and deodorizing products. Some of these products provide long-term
killing action of microorganisms responsible for cross contamination and viral
contamination. Many of these products inhibit and control the growth of over 100
viral, bacteria, fungi and yeast organisms. BioShield has continued to
successfully build brand recognition and market penetration of its new OdorFree
product line. Currently OdorFree is sold through several major supermarket
chains throughout the United States.

         BioShield has created a subsidiary to conduct electronic commerce via
the internet, Electronic Medical Distribution, Inc. or eMD. eMD seeks to
integrate product offerings for healthcare providers including point of care
medication management, electronic medical records, pharmaceutical fulfillment
and pharmaceutical care services, with a comprehensive healthcare website. eMD
launched its consumer and physician web site in January 2000. Prior to that
launch, eMD's primary focus had been organizational activities, raising capital,
gaining regulatory approvals, research and development and further investigation
into new markets. As a result, BioShield currently operates in two distinct
business segments, antimicrobial and biostatic products for use within the
retail and institutional markets through BioShield, and pharmaceutical
healthcare and related e-commerce via the internet through eMD.

         On July 7, 2000, BioShield announced an agreement to acquire up to 85%
of the outstanding stock of Arrow Magnolia International, Inc. for cash and
stock. Dallas-based Arrow Magnolia is engaged primarily in the manufacture and
distribution of specialty chemical products for use in cleaning and maintaining
equipment, and generalized maintenance and sanitation products. We have agreed
to purchase 85%, or 2,761,281 shares, of Arrow Magnolia's outstanding common
stock for a purchase price per share of $4.41 cash and .05221 of a share of
BioShield common stock, which represents $0.59 in value based upon the average
closing bid price for a share of BioShield common stock for the five day period
prior to the announcement of the transaction. We have also agreed to purchase
all the outstanding options and warrants of Arrow Magnolia for $4.75 cash over
the exercise price, and we estimate the total cost of the transaction to be
approximately $15.6 million cash and $1.6 million in stock. The transaction is
subject to satisfaction of the conditions set forth in the agreement, including
the completion of due diligence investigations.

EMPLOYMENT AGREEMENTS

         BioShield has entered into an employment agreement dated January 1,
1998 with Mr. Moses. The agreement has an initial term beginning January 1,
1998, and expiring December 31, 2003. However, the remaining term of the
agreement is extended automatically for one year on each July 1, beginning July
1, 2001, so that the agreement expires three years from that date, unless Mr.
Moses or BioShield notifies the other in writing of an intent not to renew at
least ninety days prior to the applicable July 1st. Under the agreement, Mr.
Moses is required to devote his full business time to the affairs of BioShield.
The agreement also contains a non-compete provision, which a state court may
determine not to enforce or only to partially enforce. The agreement currently
provides for a base salary at the rate of $250,000. The base salary is subject
to increase, but not decrease, as of January 1 of each year during the term of
the agreement as determined by BioShield's board of directors. The agreement
also provides for an annual performance bonus based upon a matrix of dollar
sales levels and dollar before-tax profitability. Cells within the matrix
represent specific combinations of sales and profits, with performance falling
within a particular cell resulting in a bonus to Mr. Moses expressed as a
percent of his base salary. This matrix, which allows for bonuses running from
0% to 150% of base salary, is constructed to reward the executive for reaching
specific combinations of sales and profit levels with higher sales and profit
resulting in a larger bonus. The maximum amount paid to Mr. Moses pursuant to
the matrix cannot exceed $50,000 per year. In addition, the agreement provides a
severance package in the event the executive is terminated other than for cause
or the executive terminates his agreement for good reason in an amount equal to
the sum of (a) the greater of two years of base salary on the date of
termination or the base salary, assuming no increases, payable for remaining
term of his agreement assuming no termination, plus (b) two times the average of
the annual bonuses paid or payable to Mr. Moses during the term of his
agreement, payable in six equal, consecutive monthly installments beginning no
later than thirty days after the date of termination. In addition, all
outstanding options, stock grants, shares of restricted stock or any other
equity incentive compensation will be and become fully vested and the executive
and the executive's family will be entitled to receive welfare plan benefits,
other than continued group long-term disability coverage, generally available to
executives with comparable responsibilities or positions for a period of two
years from the date of termination at the same cost to the executive as is
charged to those executives from time to time for comparable coverage.


ADVISORY BOARD

         BioShield's advisory board was organized to review and evaluate
BioShield's research and development programs and to advise BioShield generally
in addressing various scientific and business issues. BioShield generally
selects for membership persons who have experience in finance, marketing and
science. Members of the advisory board may meet as a group or individually with
management of BioShield. They are not employed by BioShield and may have
commitments to, or consulting or advisory agreements with, other entities that
may limit their availability to BioShield. These entities may also be
competitors of BioShield. BioShield is not aware of any conflict of interest
between work performed by advisors on behalf of BioShield and work performed by
them on behalf of other parties. BioShield requires each advisor to execute a
confidentiality agreement upon the


                                       77
<PAGE>   90

commencement of his or her relationship with BioShield. The agreements generally
provide that all confidential information made known to the individual during
the term of the relationship is the exclusive property of BioShield and shall be
kept confidential and not disclosed to third parties.

         The advisory board currently has one member. Dr. Cecil R. Smith, age
46, is currently chief executive officer and director in BioShield Research
Corporation, a company based in Powell, Ohio, which conducts biohazard control
evaluations for indoor environmental quality of buildings and develops
contamination control protocols for the biotechnology/pharmaceutical industry
and provides site safety analysis. Since 1987, Dr. Smith has also been assistant
vice president of environmental health and safety of Ohio State University. In
that capacity, Dr. Smith is responsible for the administration of an
environmental, occupational health and radiation safety program that includes
biological/chemical safety, safety engineering, industrial hygiene,
infectious/hazardous waste management, safety training and environmental
compliance. Since 1991, Dr. Smith has also served as assistant professor to Ohio
State University School of Public Health. Dr. Smith received his master's and
Ph.D. degrees in public health from the University of North Carolina. In 1983
and 1980, respectively, Dr. Smith received his B.S. in microbiology from North
Dakota State University in 1977 and his B.A. in biology and natural science from
Gustavus Adolphus College in 1975.

         Advisors receive reimbursement of travel expenses connected with
BioShield business and stock options for consultation services, which include
assisting BioShield in the development of a marketing plan as well as research
plan to elucidate the biological effects, safety and efficacy of BioShield's
products and assisting BioShield in analyzing data from research trials and
other studies concerning BioShield's products. BioShield anticipates that each
advisor will devote approximately six days per year to the affairs of BioShield
in his capacity as an advisor, consisting of three one-day meetings of the
advisory board to be held each year and preparation for these meetings.


INDEMNIFICATION OF DIRECTORS AND OFFICERS

         BioShield's bylaws provide for BioShield to indemnify each director and
officer of BioShield against liabilities imposed upon him, including reasonable
amounts paid in settlement, and expenses incurred by him in connection with any
claim made against him or any action, suit or proceeding to which he may be a
party by reason of his being or having been a director or officer of BioShield.
BioShield has also entered into indemnification agreements with each officer and
director under which BioShield will, in general, indemnify these persons to the
maximum extent permitted by BioShield's bylaws and the Georgia law against any
expenses incurred in connection with any actual or threatened action or
proceeding to which a director or officer is made or threatened to be made a
party because that person is or was a director or officer of BioShield. These
provisions may reduce the likelihood of derivative litigation against directors
and may discourage or deter stockholders or management from suing directors for
breaches of their duty of care, even though litigation of this type, if
successful, might otherwise benefit BioShield and its stockholders.

         To the extent that indemnification of liabilities arising under the
Securities Act may be permitted to directors, officers, or persons controlling
BioShield, BioShield has been informed that in the opinion of the SEC this
indemnification is against public policy as expressed in the Securities Act and
is therefore unenforceable. In the event that a claim for indemnification
against these liabilities, other than the payment by BioShield of expenses
incurred or paid by a director, officer, or controlling person of BioShield in
the successful defense of any action, suit, or proceeding, is asserted by a
director, officer, or controlling person, BioShield will, unless in the opinion
of its counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether this indemnification by
it is against public policy as expressed in the Securities Act and will be
governed by the final adjudication of this issue.

STOCK OPTION PLANS

         The board of directors approved and the stockholders of BioShield
adopted a directors' stock option plan in 1996. In December 1997, the board of
directors adopted and the stockholders of BioShield approved a stock incentive
plan. The stock incentive plan was amended by the board of directors in December
1998 to increase the number of shares of common stock which could be issued
under the plan to 1,200,000, and subsequently again amended the plan to increase
the number of shares to 2,000,000. In May 1999, BioShield registered 1,200,000
shares subject to the incentive plan with the Securities and Exchange Commission
on Form S-8. In March 2000,


                                       78
<PAGE>   91

BioShield registered the shares subject to the directors' stock option plan with
the Securities and Exchange Commission on Form S-8.

         TERMS OF INCENTIVE PLAN. The incentive plan provides BioShield with
increased flexibility to grant equity-based compensation to key employees,
officers and consultants of BioShield. The purpose of the incentive plan is to:

         -        provide incentives to stimulate individual efforts toward
                  BioShield's long-term growth and profitability;

         -        encourage stock ownership by officers, key employees and
                  consultants by enabling them to acquire a proprietary interest
                  in BioShield in the form of shares of common stock and to
                  receive compensation based on appreciation in the value of the
                  common stock; and

         -        provide a means of obtaining, rewarding and retaining key
                  personnel.

         BioShield has reserved 2,000,000 shares of common stock for issuance
pursuant to awards that may be made under the incentive plan. As of July 15,
2000, 906,000 options have been granted under the incentive plan, of which
355,000 are immediately exercisable.

         The nature, terms and conditions of awards under the incentive plan are
determined by the compensation committee of the board of directors. The members
of the compensation committee are selected by the board of directors, and are
currently Mr. Garner, Mr. Miller and Mr. Lamle. The incentive plan permits the
compensation committee to make awards of common stock, incentive stock options
or non-qualified stock options with the following terms and conditions:

         TERMS AND CONDITIONS OF ALL STOCK INCENTIVES. The number of shares of
common stock as to which a stock incentive may be granted are determined by the
compensation committee. Each stock incentive is governed by a stock incentive
agreement or stock incentive program, in each case containing terms, conditions
and restrictions approved by the compensation committee. Stock incentives are
not transferable or assignable except by will or by the laws of descent and
distribution and are exercisable only by the recipient during his or her
lifetime or by the recipient's legal representative in the event of the
recipient's death or disability.

         STOCK AWARDS. The number of shares of common stock, subject to a stock
award and restrictions or conditions on the shares, if any, are determined by
the compensation committee. The compensation committee may require a cash
payment from the recipient in an amount no greater than the total fair market
value of the shares of common stock awarded, as determined at the date of grant.

         OPTIONS. Options may be either incentive stock options, as described in
Section 422 of the Internal Revenue Code, or non-qualified stock options. The
exercise price of each option will be determined by the compensation committee
but may not be less than the fair market value of the common stock on the date
the option is granted. In the case of an option granted to an owner of more than
10% of BioShield's outstanding stock, the exercise price may not be less than
110% of the fair market value of the common stock on the date the option is
granted. The exercise price may not be changed after the option is granted, and
options may not be surrendered in consideration of, or exchanged for, a grant of
a new option with a lower exercise price. Incentive stock options will expire 10
years after the date of grant. Non-qualified stock options will expire on the
date provided in the stock incentive agreement. Payment for shares of common
stock purchased upon exercise of an option may be made in any form or manner
authorized by the compensation committee. In the event of a recipient's
termination of employment, the option or unexercised portion of the option will
expire within three months after the date of termination, except that in the
case of the recipient's death or disability, that period is extended to one
year. The compensation committee may set longer time limits in the stock
incentive agreement, although in these cases incentive stock option treatment
will not be available under the Code.

         TERMINATION AND AMENDMENT OF THE INCENTIVE PLAN. The board of directors
may amend or terminate the incentive plan without stockholder approval at any
time. The board may condition any amendment on the approval of the stockholders
if this approval is necessary or advisable with respect to tax, securities or
other laws. No termination or amendment without the consent of the holder of a
stock incentive may adversely affect the rights of a holder under the terms of
that stock incentive.


                                       79
<PAGE>   92

         CHANGES IN CAPITALIZATION. The incentive plan provides for an
adjustment of the number of shares of common stock reserved and subject to
awards issued pursuant to the incentive plan and of the exercise price of
options granted under the incentive plan in the event of changes in the
capitalization of BioShield, including stock splits, reverse stock splits, stock
dividends or any other increase or decrease in the number of shares of common
stock outstanding that does not result in receipt of consideration by BioShield.
In the event of a merger, consolidation or other reorganization of BioShield or
a tender offer for its shares of common stock, the committee may take that
action to reflect the effect of the transaction.

         FEDERAL INCOME TAX CONSEQUENCES. The following discussion outlines
generally the federal income tax consequences of the receipt of options under
the incentive plan. Individual circumstances may vary these results. The federal
income tax laws and regulations are frequently amended, and each participant
should rely on his or her own tax counsel for advice regarding federal income
tax treatment under the incentive plan. If the recipient is subject to Section
16(b) of the Securities Exchange Act of 1934, as amended, special rules may
apply to determine the federal income tax consequences of option exercises.
Participants in the incentive plan should consult their own tax advisors as to
the specific tax consequences applicable to them and to the tax consequences
applicable to other types of stock incentives that may be awarded under the
incentive plan.

         INCENTIVE STOCK OPTIONS. The recipient of an incentive stock option is
not subject to any federal income tax upon the grant of the option pursuant to
the incentive plan, nor does the grant of an incentive stock option result in an
income tax deduction for BioShield. A recipient will not recognize income for
federal income tax purposes and BioShield normally will not be entitled to any
federal income tax deduction. However, the excess of the fair market value of
the shares transferred upon the exercise of the incentive stock option over the
exercise price for these shares generally will constitute an item of alternative
minimum tax adjustment to the recipient for the year in which the option is
exercised. Thus, certain recipients may increase their federal income tax
liability as a result of the exercise of an incentive stock option under the
alternative minimum tax rules under the Code. If the shares of common stock
transferred pursuant to the exercise of an incentive stock option are disposed
of within two years from the date the option is granted or within one year from
the date the option is exercised, the recipient generally will recognize
ordinary income equal to the lesser of (1) the gain recognized; that is, the
excess of the amount realized on the disposition over the exercise price, or (2)
the excess of the fair market value of the shares transferred upon exercise over
the exercise price for the shares. The balance, if any, of the recipient's gain
over the amount treated as ordinary income on disposition generally will be
treated as long- or short-term capital gain depending upon whether the holding
period applicable to long-term capital assets is satisfied. BioShield normally
would be entitled to a federal income tax deduction equal to any ordinary income
recognized by the recipient, provided BioShield satisfies applicable federal
income tax withholding requirements. If the shares of common stock transferred
upon the exercise of an incentive stock option are disposed of after the holding
periods have been satisfied, the disposition will result in a long-term capital
gain or loss treatment applicable to the difference between the amount realized
on the disposition and the exercise price. BioShield will not be entitled to a
federal income tax deduction as a result of a disposition of the shares after
these holding periods have been satisfied.

         NON-QUALIFIED OPTIONS. A recipient will not recognize income upon the
grant of a non-qualified option or at any time prior to the exercise of the
option or a portion thereof. At the time the recipient exercises a non-qualified
option, he or she will recognize compensation taxable as ordinary income in an
amount equal to the excess of the fair market value of the common stock on the
date the option is exercised over the price paid for the common stock, and
BioShield will then be entitled to a corresponding deduction. Depending upon the
period for which shares of common stock are held after exercise, the sale or
other taxable disposition of shares acquired through the exercise of a
non-qualified option generally will result in a short- or long-term capital gain
or loss equal to the difference between the amount realized on the disposition
and the fair market value of these shares when the non-qualified option was
exercised. Special rules apply to a participant who exercises a non-qualified
option by paying the exercise price in whole or in part by a transfer of shares
of common stock to BioShield.

         DIRECTOR PLAN. The purpose of the director plan is to provide an
incentive to outside directors and members of BioShield's advisory board for
continuous association with BioShield and to reinforce the relationship between
participants' rewards and stockholder gains. BioShield has reserved 1,000,000
shares of common stock for awards that may be made under the director plan. As
of July 15, 2000, 595,000 options have been granted under the Director Plan, all
of which are immediately exercisable.

         In June 1998, Timothy C. Moses and Jacques Elfersy contributed
approximately $50,000 of capital to BioShield. Subsequent to June 30, 1998,
Messrs. Moses and Elfersy contributed an additional $325,000 of capital to
BioShield. Those contributions were funded by the private sale to accredited
investors of 124,995 shares of common stock of BioShield owned by these persons
since 1995 at a purchase price of $3.00 per share.

         In January, March, and June 1998, Judith B. Turner, the mother-in-law
of Timothy C. Moses, lent BioShield $30,000, $25,000, and $25,000, respectively.
Those sums were repaid by BioShield from the proceeds of BioShield's initial
public offering.

         Upon consummation of BioShield's initial public offering, Messrs. Moses
and Elfersy received $307,133 in the aggregate from BioShield representing
repayment of accrued and unpaid salary due and payable by BioShield for their
employment for the period June 1995 through June 30, 1998.

         In May of 1999, the board of directors granted to each of Timothy C.
Moses and Jacques Elfersy five year fully vested options to purchase 2,250,000
shares of eMD at a price of $2.00 per share.

         Although BioShield believes that the foregoing transactions were on
terms as favorable to BioShield as would have been available from unaffiliated
third parties in arm's length transactions, there is no assurance that this is
the case. BioShield represents that all future material affiliated transactions
and loans will be made or entered into on terms that are as favorable to
BioShield as those that could be obtained from unaffiliated third parties, and
all future material affiliated transactions and loans, and any forgiveness of
loans, will be approved by a majority of BioShield's independent directors who
do not have an interest in the transactions and who will have access, at
BioShield's expense, to BioShield's counsel or to independent legal counsel.
There is no assurance, however, that future transactions or arrangements between
BioShield and its affiliates will be advantageous, that conflicts of interest
will not arise or that if conflicts do arise, that they will be resolved in
favor of BioShield.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

         Section 16(a) of the Exchange Act requires BioShield's officers and
directors, and persons who own more than 10% of BioShield's common stock, to
file reports of ownership and changes in ownership with the SEC and the NASD,
and furnish BioShield with copies of those reports. Based solely on its review
of copies of the forms received by it, BioShield believes that, during the
period July 1, 1999, to June 30, 2000 all filing requirements applicable to its
officers, directors and greater than 10% beneficial owners were complied with;
except that in the case of the appointment of each of Mr. Edward U. Miller and
Mr. Martin Savarick to the board of directors in January, 2000, required forms
were not timely filed, and in Mr. Savarick's case, two acquisitions of shares
were not timely reported by the filing of a required form. In addition, a
required form was not timely filed in connection with the appointment of Scott
Parliament as Chief Financial Officer.

                            INFORMATION REGARDING AHT

         AHT is a national provider of internet-based clinical e-commerce among
physicians, other healthcare providers, and healthcare organizations. AHT is
focused on automating laboratory and prescription transactions, the two most
frequent clinical transactions initiated by physicians today. AHT's products
principally focus on laboratory and prescription connectivity and transaction
processing, including, within the laboratory suite of applications, Dr. Chart
(R), Compliance Monitor (TM) and its electronic prescription writing product,
@Rx (TM).

         AHT's Dr. Chart (R) products link clinical laboratories to physicians,
enabling them to initiate laboratory orders on-line and to view those results
on-line on a real-time basis from their desktop PCs. Dr. Chart (R) is also
Web-enabled, making the clinical information available on a real-time basis to
any physician and clinician equipped with a standard office PC and a Web
browser. AHT's laboratory transaction management software suite effectively
manages test data dictionaries, other laboratory interfaces, and other sources
of information, integrating disparate healthcare institutions and providing
connectivity to community-based providers within an integrated delivery system.

         Compliance Monitor (TM) software assists clinical laboratories with
Medicare and Health Care Financing Administration, or HCFA, compliance.
Compliance Monitor (TM) software assists clinical laboratories in organizing
information for compliance with Medicare rules and HCFA regulations.

         @Rx (TM) is an internet tool that manages all phases of the
prescription writing process from the physician's office, including screening
for drug interactions and insurance medication preferences. The @Rx (TM)
electronic prescription management service enables physicians and other
authorized healthcare providers to manage the entire prescription writing
process over the internet utilizing technology designed to maximize the security
and confidentiality of patient health information. AHT's management believes
that the prescription transaction service has the potential, in some cases, to
replace both paper prescriptions and phone calls regarding prescriptions with an
efficient online transaction with the provider's clinical management system.
This may potentially save time and labor in the ordering process, while
providing more accurate and informative orders.

     UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS OF BIOSHIELD AND AHT


         The following unaudited pro forma condensed combined financial
statements give effect to the acquisition by BioShield of AHT in a transaction
to be accounted for as a purchase. The unaudited pro forma condensed combined
financial statements are based on the historical consolidated financial
statements and related notes of BioShield and AHT, which are incorporated by
reference to this joint proxy statement/prospectus, with the exception that the
Statements of Operations for AHT were prepared as if AHT presented its results
on the same fiscal period as BioShield. The unaudited pro forma condensed
combined balance sheet has been prepared to reflect the acquisition by BioShield
of AHT as of March 31, 2000. The unaudited pro forma condensed combined
statements of operations combine the results of operations of BioShield and of
AHT for the year ended June 30, 1999 and the nine months ended March 31, 2000 as
if the acquisition occurred on July 1, 1998. These unaudited pro forma condensed
combined financial statements should be read together with the financial
statements and related notes of BioShield and AHT, both incorporated by
reference into this joint proxy statement/prospectus. The historical financial
statements of BioShield and AHT are not necessarily indicative of the financial
condition or results of operations of such operations on a prospective combined
basis.

         BioShield has agreed to purchase AHT for cash and stock valued at
approximately $30.8 million for AHT's 11.1 million common shares outstanding.
The purchase price consists of approximately $8.3 million in cash, reflecting
severance payments, debt settlements, estimated closing costs and cash
settlement of a potential dispute, and approximately 2.6 million shares of
BioShield common stock valued at $22.5 million at the previous five day average
closing bid price of $8.49 on July 28, 2000.

         For purposes of this pro forma information, the purchase price has been
allocated to the assets of AHT. The excess of the purchase price over the fair
value of the assets acquired has been allocated to goodwill. The final
allocation may differ from that used in the unaudited pro forma condensed
financial statements.

         The unaudited pro forma condensed combined financial statements are
based on the estimates and assumptions set forth in the notes to such
statements, which are preliminary and have been made solely for the purpose of
developing such pro forma information. The unaudited pro forma condensed
combined financial statements are not necessarily indicative of the results that
would have been achieved had such transactions been consummated as of the dates
indicated, or that may be achieved in the future, or the results that would have
been realized had the entities been a single entity during those periods. These
unaudited pro forma condensed combined financial statements should be read
together with the notes of BioShield and AHT, and other information pertaining
to BioShield and AHT including "Risk factors" and any documents incorporated by
reference into this joint proxy statement/prospectus.

                BIOSHIELD TECHNOLOGIES, INC. AND AHT CORPORATION
               NOTES TO PRO FORMA CONDENSED COMBINED BALANCE SHEET


Pro forma adjustments are as follows:

         a)       Based on the per share prices of BioShield and AHT and the
                  effective exchange ratios at July 28, 2000, the aggregate
                  purchase price for AHT is approximately $30.8 million.
                  Assuming no outstanding AHT options and warrants are exercised
                  prior to the closing of the merger, the purchase price
                  consists of approximately $8.3 million in cash and
                  approximately 2.6 million shares of BioShield common stock
                  valued at $22.5 million. This entry reflects the value of cash
                  and BioShield common stock given in exchange for AHT common
                  stock and the payment of severance to officers and employees
                  of $2.0 million, debt settlements of $4.9 million, estimated
                  closing costs of $0.5 million, $3.0 million in non-cash
                  litigation settlements and $0.8 million in cash settlement of
                  a potential dispute.

         b)       This adjustment reflects the excess of the aggregate purchase
                  price over the fair value of the assets acquired.

         c)       This adjustment reflects the forgiveness of AHT officer loans
                  in connection with the purchase.

         d)       This adjustment reflects the payoff of a note and the
                  write-off of the associated capitalized issuance costs and
                  discounts.

    UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS OF BIOSHIELD AND ARROW
                                    MAGNOLIA

         BioShield has agreed to purchase Arrow Magnolia for cash and stock
valued at approximately $17.0 million for 85% of Arrow Magnolia's 2.7 million
common shares outstanding. The purchase price consists of approximately $15.4
million in cash and approximately 192,000 shares of BioShield common stock
valued at $1.6 million at the previous five day average closing bid price of
$8.49 on July 28, 2000. As a result of this potential acquisition, unaudited pro
forma combined statements of BioShield and Arrow Magnolia, as well as unaudited
pro forma combined statements of BioShield, AHT and Arrow Magnolia have been
included in this joint proxy statement/prospectus.

         The following unaudited pro forma condensed combined financial
statements give effect to the acquisition by BioShield of Arrow Magnolia in a
transaction to be accounted for as a purchase. The unaudited pro forma condensed
combined financial statements are based on the historical consolidated financial
statements and related notes of BioShield and Arrow Magnolia, which are
incorporated by reference to this proxy statement/prospectus, with the exception
that the Statements of Operations for Arrow Magnolia were prepared as if Arrow
Magnolia presented its results on the same fiscal period as BioShield. The
unaudited pro forma condensed combined balance sheet has been prepared to
reflect the acquisition by BioShield of Arrow Magnolia as of March 31, 2000. The
unaudited pro forma condensed combined statements of operations combine the
results of operations of BioShield and of Arrow Magnolia for the year ended June
30, 1999 and the nine months ended March 31, 2000 as if the acquisition occurred
on July 1, 1998. These unaudited pro forma condensed combined financial
statements should be read together with the financial statements and related
notes of BioShield and Arrow Magnolia, both incorporated by reference into this
proxy statement/prospectus. The historical financial statements of BioShield and
Arrow Magnolia are not necessarily indicative of the financial condition or
results of operations of such operations on a prospective combined basis.

         For purposes of this pro forma information, the purchase price has been
allocated to the assets of Arrow Magnolia. The excess of the purchase price over
the fair value of the assets acquired has been allocated to goodwill. The final
allocation may differ from that used in the unaudited pro forma condensed
financial statements.

         The unaudited pro forma condensed combined financial statements are
based on the estimates and assumptions set forth in the notes to such
statements, which are preliminary and have been made solely for the purpose of
developing such pro forma information. The unaudited pro forma condensed
combined financial statements are not necessarily indicative of the results that
would have been achieved had such transactions been consummated as of the dates
indicated, or that may be achieved in the future, or the results that would have
been realized had the entities been a single entity during those periods. These
unaudited pro forma condensed combined financial statements should be read
together with the notes of BioShield and Arrow Magnolia, and other information
pertaining to BioShield and Arrow Magnolia including "Risk factors" and any
documents incorporated by reference into this joint proxy statement/prospectus.

               NOTES TO PRO FORMA CONDENSED COMBINED BALANCE SHEET


Pro forma adjustments are as follows:

         a)       Based on the per share prices of BioShield and Arrow Magnolia
                  and the effective exchange ratios at July 28, 2000, the
                  aggregate purchase price for Arrow Magnolia is approximately
                  $17 million. Assuming outstanding Arrow Magnolia options and
                  warrants are exercised prior to the closing of the merger, the
                  purchase price consists of approximately $15.4 million in cash
                  and approximately 192,000 shares of BioShield common stock
                  valued at $1.6 million. This entry reflects the value of cash
                  and BioShield common stock given in exchange for 85% of Arrow
                  Magnolia common stock.

         b)       This adjustment reflects the excess of the aggregate purchase
                  price over the fair value of the assets acquired.

         c)       This adjustment reflects bank debt to be acquired to finance
                  the purchase of Arrow Magnolia.

         d)       This adjustment reflects issuance of BioShield Series B
                  Preferred stock to finance the purchase of Arrow Magnolia.

         e)       This adjustment reflects the 15% minority interest in Arrow
                  Magnolia owned by other entities subsequent to the
                  acquisition.

     UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS OF BIOSHIELD, AHT AND
                                 ARROW MAGNOLIA


         The following unaudited pro forma condensed combined financial
statements give effect to the acquisition by BioShield of AHT and Arrow Magnolia
in transactions to be accounted for as purchases. The unaudited pro forma
condensed combined financial statements are based on the historical consolidated
financial statements and related notes of BioShield, AHT and Arrow Magnolia,
which are incorporated by reference to this proxy statement/prospectus, with the
exception that the Statements of Operations for AHT and Arrow Magnolia were
prepared as if AHT and Arrow Magnolia presented their results on the same fiscal
period as BioShield. The unaudited pro forma condensed combined balance sheet
has been prepared to reflect the acquisition by BioShield of AHT and Arrow
Magnolia as of March 31, 2000. The unaudited pro forma condensed combined
statements of operations combine the results of operations of BioShield and of
AHT and Arrow Magnolia for the year ended June 30, 1999 and the nine months
ended March 31, 2000 as if the acquisition occurred on July 1, 1998. These
unaudited pro forma condensed combined financial statements should be read
together with the financial statements and related notes of BioShield, AHT and
Arrow Magnolia, all incorporated by reference into this proxy
statement/prospectus. The historical financial statements of AHT and Arrow
Magnolia are not necessarily indicative of the financial condition or results of
operations of such operations on a prospective combined basis.

         BioShield has agreed to the purchase of AHT and Arrow Magnolia, subject
to conditions specified in the acquisition agreements, including, in the case of
Arrow Magnolia, completion of a due diligence examination. Each purchase
agreement is independent of the other. Therefore, it is possible that both
proposed purchases will be closed.

         For purposes of this pro forma information, the purchase price of each
entity has been allocated to the assets of the entity being acquired. The excess
of the purchase prices over the fair value of the assets acquired has been
allocated to goodwill. The final allocation may differ from that used in the
unaudited pro forma condensed financial statements.

         The unaudited pro forma condensed combined financial statements are
based on the estimates and assumptions set forth in the notes to such
statements, which are preliminary and have been made solely for the purpose of
developing such pro forma information. The unaudited pro forma condensed
combined financial statements are not necessarily indicative of the results that
would have been achieved had such transactions been consummated as of the dates
indicated, or that may be achieved in the future, or the results that would have
been realized had the entities been a single entity during those periods. These
unaudited pro forma condensed combined financial statements should be read
together with the notes of BioShield and Arrow Magnolia, and other information
pertaining to BioShield and Arrow Magnolia including "Risk factors" and any
documents incorporated by reference into this joint proxy statement/prospectus.

upon request. For information on where to obtain a copy of BioShield's articles

AUTHORIZED CAPITAL STOCK

         Under BioShield's articles of incorporation, BioShield is authorized to

shares of preferred stock with rights to be determined by BioShield's board of
directors. Five hundred shares of preferred stock have been designated series B
convertible preferred stock.


COMMON STOCK

         COMMON STOCK OUTSTANDING. As of June 29, 2000, there were 8,339,073
shares of common stock issued and outstanding. Additionally, 35,000 shares of
BioShield common stock were held in the treasury of BioShield and 3 million
shares of common stock were reserved for issuance in accordance with BioShield's
employee benefit plans. The outstanding shares of BioShield common stock are,
and the shares of BioShield common stock issued under the merger agreement will
be, duly authorized, validly issued, fully paid and nonassessable.

         VOTING RIGHTS. Each holder of BioShield common stock is entitled to one
vote for each share of BioShield common stock held of record on the applicable
record date on all matters submitted to a vote of stockholders.

         DIVIDEND RIGHTS. The holders of BioShield common stock share in any
dividends paid on the common stock if BioShield's board of directors declares
dividends out of funds that are legally available.

         RIGHTS UPON LIQUIDATION. In the event of liquidation, each share of
BioShield common stock is entitled to share pro rata in any distribution of
BioShield's assets after payment or providing for the payment of liabilities and
the liquidation preference of any outstanding BioShield preferred stock.

         RANK. All shares of common stock rank junior to all shares of series B
convertible preferred stock regarding preferences for distributions and payments
in the event of liquidation.

         PREEMPTIVE RIGHTS. Holders of BioShield common stock have no preemptive
rights to purchase, subscribe for or otherwise acquire any unissued or treasury
shares or other securities.

         REDEMPTION. No redemption provisions apply to the BioShield common
stock.


SERIES B CONVERTIBLE PREFERRED STOCK

         SERIES B CONVERTIBLE PREFERRED STOCK OUTSTANDING. As of the date of
this prospectus, BioShield's board of directors has classified 500 shares of
preferred stock as series B convertible preferred stock and all 500 shares are
outstanding.

         VOTING RIGHTS. The holders of series B preferred stock are not entitled
to vote, except as required by law.

         DIVIDEND RIGHTS. Holders of series B preferred stock are not entitled
to receive dividends. If any shares of series B preferred stock are outstanding,
BioShield may not declare, pay or make any dividends or other distributions on
any of the common stock unless BioShield gives written notice to the holders of
the series B preferred stock at least thirty days before either the record date
taken for the dividend payment or another


                                       95
<PAGE>   108

distribution and BioShield obtains the written consent of the holders of a
majority of the outstanding shares of series B convertible preferred stock.

         BioShield may declare and pay a dividend in cash on its common stock if
BioShield meets two conditions. First, BioShield must pay to each holder of
shares of series B preferred stock cash equal to the amount this holder would
have received if the holder's shares of series B preferred stock had been
converted to common stock one business day before the record date for the
dividend. Second, after making any required payments, including payments to the
holders of shares of series B convertible preferred stock, BioShield must have
in cash or cash equivalents an amount equal to the sum of:

         -        all of BioShield's liabilities on our most recently available
                  balance sheet;

         -        the amount of any indebtedness BioShield or any of BioShield's
                  subsidiaries incurs since BioShield's most recent balance
                  sheet; and

         -        120% of the amount payable to all holders of any shares of any
                  class of BioShield preferred stock assuming a liquidation as
                  the date of our most recently available balance sheet.

         RIGHTS UPON LIQUIDATION. If there is a liquidation or dissolution of
BioShield, each holder of series B preferred stock will receive a liquidation
preference prior to any payments made to holders of any class of our capital
stock that ranks junior to the series B convertible preferred stock. This
preference is an amount per share equal to the sum of:

         -        $20,000, the stated value of the series B convertible
                  preferred stock; and

         -        a premium of 5% per year of the stated value the series B
                  preferred stock from the date of its issuance.

         If there are insufficient funds to pay the full amount due to the
holders of series B preferred stock and other classes of BioShield preferred
stock rank equally with the series B preferred stock regarding these payments,
then each holder of series B preferred stock will share equally in any available
funds according to their liquidation preferences.

         BioShield's purchase or redemption of its stock in any manner permitted
by law will not be regarded as a liquidation or dissolution of BioShield.
Similarly, BioShield's consolidation or merger with or into any other person and
the sale or transfer by us of less than substantially all of our assets will be
not deemed to be a liquidation or dissolution.

         RANK. The series B preferred stock will rank greater than any series of
common or preferred stock issued by BioShield in the future. We may not
authorize or issue capital stock that ranks senior or equal to the series B
preferred stock without the written consent of the holders of at least a
majority of the outstanding shares of series B convertible preferred stock.
Without the written approval of at least a majority of the outstanding shares of
series B convertible preferred stock, we may not amend our articles of
incorporation or bylaws, or make any resolution of the board of directors with
the Georgia Secretary of State containing provisions that may materially and
adversely affect or impair the rights of the holders of shares of series B
preferred stock relative to the holders of our common stock or holders of any
other class of our capital stock. If we merge or consolidate with or into
another corporation, the series B preferred stock must retain its relative
rights.

         PREEMPTIVE RIGHTS. Holders of series B preferred stock have no
preemptive rights to purchase, subscribe for or otherwise acquire any unissued
or treasury shares or other securities.

         REDEMPTION. At any time after the earlier of ninety days after issuance
of the series B preferred stock or the effective date of a registration
statement covering the shares of common stock issuable upon conversion of the
series B convertible preferred stock, BioShield has the right to redeem the
series B preferred stock if we meet some conditions. These conditions include
that we have cash, credit or standby underwriting facilities available to fund
the redemption. The redemption price is calculated as 125% of the original
purchase price. All series B preferred stock outstanding as of June 14, 2003
will be automatically converted according to the conversion provisions of the
series B convertible preferred stock.

         CONVERSION. Each share of series B preferred stock is convertible into
the number of shares of BioShield common stock equal to its stated value,
$20,000, plus a 5% premium of the stated value each year from the date the
series B preferred stock is issued divided by the conversion price. The
conversion price is equal to 90% of the average lowest of the closing bid and
ask prices of our common stock for any three trading days in the ten trading day
period before the conversion.

         If all the series B preferred stock were converted, it would convert
into:

</TABLE>

         Under the conversion price formula, there is no ceiling on the number
of shares of common stock into which the series B preferred stock can be
converted, and, as the price of the common stock decreases, the number of shares
of common stock underlying the shares of series B preferred stock continues to
increase. The series B preferred stock is likely to be converted at a rate at or
below the common stock's market price, and the lower the common stock's market
price at the time the holder converts, the more shares of common stock the
holder will get in the conversion. To the extent a holder of series B preferred
stock converts and then sells the shares of common stock, the common stock's
market price may decrease due to the additional shares in the market, allowing
the selling holder to convert other series B preferred stock into greater
amounts of common stock, the sale of which could further depress the market
price for the common stock. The downward pressure on the market price of the
common stock as a holder of the series B preferred stock converts and sells
common stock could encourage short sales by others, placing further downward
pressure on the market price of the common stock. The conversion of the
outstanding shares of series B preferred stock may result in substantial
dilution to the interest of other common stockholders.

         Please see BioShield's articles of incorporation for more detailed
information about BioShield's preferred stock. You may obtain a copy of
BioShield's articles of incorporation by following the instructions in the
section titled "Where you can find more information" that begins on page __ of

AUTHORIZED CAPITAL STOCK

         The AHT certificate of incorporation authorizes AHT to issue stock
consisting of 30,000,000 shares of common stock, $.01 par value per share, and
5,000,000 shares of preferred stock, $.01 par value per share. The BioShield
articles of incorporation authorizes BioShield to issue stock consisting of
40,000,000 shares of common stock, no par value per share, and 10,000,000 shares
of preferred stock, no par value per share.


NUMBER AND ELECTION OF DIRECTORS; STAGGERED BOARD

         NUMBER OF DIRECTORS. The number of directors on the AHT board of
directors is fixed by a bylaw or amendment to a bylaw adopted by the AHT board
of directors. BioShield's board of directors will consist of no less than three
or more than twenty-one directors.

         ELECTION OF DIRECTORS. AHT's directors are elected by a plurality of
votes at stockholder meetings and hold office until their resignation or
removal. Successors to the class of BioShield's directors whose term expires at
each annual meeting of stockholders are elected at that annual meeting.

         STAGGERED BOARD. AHT has three classes of board members whose
three-year terms are staggered, currently having terms expiring in 2000, 2001,
and 2002 respectively. BioShield's directors are divided into three classes,
which each serve a three-year term.


STANDARDS OF CONDUCT FOR DIRECTORS

         The standards of conduct of AHT's directors are governed by Delaware
law. Under Delaware law, the business and affairs of AHT are managed by or under
the direction of the AHT board of directors. Generally, directors of Delaware
corporations are subject to a duty of loyalty, a duty of care and a duty of
candor to the stockholders. The directors of AHT must act with the normal common
sense of a prudent businessperson in fulfilling their obligations as directors.

         The standards of conduct of BioShield's directors are governed by
Georgia law. Georgia law provides that a director must discharge his duties as a
director in a manner he believes in good faith to be in the best interests of
the corporation, and with the care an ordinary prudent person in a like position
would exercise under similar circumstances.


LIMITATION OF LIABILITY OF DIRECTORS AND OFFICERS

         The directors of AHT are not generally liable to AHT for breach of
their fiduciary duties, except for any breach of the duty of loyalty, for acts
or omissions not in good faith or involving intentional misconduct or knowing
violation of the law, for liability for unlawful payment of dividends or stock
purchases or where the director received an improper benefit.

         The directors of BioShield are not personally liable to BioShield if
they performed the duties of their office in good faith and with the care an
ordinary person would exercise. However, under Georgia law, a director is
personally liable to the corporation if he votes for or assents to a
distribution:

         -        that violates the articles of incorporation;

         -        made even though, as a result, BioShield would not be able to
                  pay its debts as they become due in the normal course of
                  business; or

         -        made even though, as a result, BioShield's total assets would
                  be less than the sum of its total liabilities plus the amount
                  that would be needed, if BioShield were to be dissolved at the
                  time of the distribution, to satisfy the preferential rights
                  of stockholders upon dissolution whose preferential rights are
                  superior to those receiving the distribution.

<PAGE>   111

INDEMNIFICATION OF DIRECTORS AND OFFICERS

         AHT indemnifies its directors and officers to the fullest extent
permitted under Delaware law. Delaware law permits AHT to indemnify its officers
and directors if they are made or threatened to be made a party to any type of
proceeding because of their role as director of officer of AHT, except for any
action on behalf of AHT. AHT's directors and officers are indemnified against
expenses, judgements, fines and amounts paid in settlement actually and
reasonably incurred in connection with the proceeding if the director or officer
acted in good faith and in a manner he or she reasonably believed to be in or
not opposed to the best interests of the corporation. In a criminal proceeding,
AHT may indemnify its directors and officers if the director or officer had no
reasonable cause to believe that his or her conduct was unlawful.

         BioShield indemnifies its directors and officers in any legal
proceeding brought against them because of their position as a director or
officer of BioShield, to the extent that they are successful in their defense or
if the director or officer acted in good faith or in a manner not opposed to the
best interests of BioShield. BioShield will advance funds to pay for the
reasonable expenses incurred by its directors or officers in these suits if the
director or officer delivers to BioShield a written affirmation of his or her
good faith belief that he or she has met the relevant standard of conduct.


REMOVAL OF DIRECTORS

         Any director of AHT or the entire AHT board of directors may be
removed, with or without cause, at any time by the vote of the holders of a
majority of the shares of AHT common stock then entitled to vote at an election
of directors.

         The BioShield common stockholders do not have the right to remove any
of BioShield's directors except for cause and by the affirmative vote of the
holders of at least 66 and 2/3% of the outstanding shares of BioShield's voting
stock. Any of BioShield's directors elected by a voting group of stockholders
may be removed only by the stockholders of that voting group.


ACTION BY WRITTEN CONSENT

         Any action required or permitted to be taken by the AHT common
stockholders must be taken at an annual or special meeting of the AHT common
stockholders and may not be taken by written consent in lieu of a meeting.

         Any action required or permitted to be taken by the BioShield
stockholders must be taken at an annual or special meeting of the BioShield
stockholders and may not be taken by written consent in lieu of a meeting.


AMENDMENTS TO THE CHARTER

         Any amendment to the AHT certificate of incorporation must be approved
by the holders of a majority of the outstanding shares of AHT common stock.

         Amendments to the BioShield articles of incorporation, except for
amendments to the provisions concerning the duties of BioShield's board of
directors and amendment of the articles of incorporation, must be made by the
affirmative vote of the holders of a majority of the shares of each class of
BioShield stock entitled to vote. The provisions concerning the duties of
BioShield's board of directors and amendment of the articles of incorporation
may not be amended unless the action is approved by the affirmative vote of the
holders of at least 66 2/3% of the outstanding shares of BioShield stock,
excluding from the number of shares deemed to be outstanding and from the vote
on the amendment all shares owned beneficially by any interested stockholder.

INSPECTION OF DOCUMENTS

         Stockholders of AHT, upon written demand under oath stating the reason
for wanting to inspect the corporation's documents, have the right during AHT's
normal business hours to inspect for any proper purpose the corporation's stock
ledger, a list of its stockholders, and its other books and records and to make
copies of these documents. A proper purpose means a purpose reasonably related
to that person's interest as a stockholder.

         BioShield's board of directors has the power to determine which
accounts, books and records may be opened to the inspection of stockholders,
except those that are required by law to be open to inspection. Under Georgia
law, BioShield stockholders may inspect and copy, during normal business hours,
minutes of meetings of the BioShield board of directors or stockholders,
accounting records and the record of stockholders. Any request to inspect these
records must be made in good faith and for a proper purpose reasonably related
to a legitimate interest as a stockholder of BioShield. These rights are
available only to stockholders owning 2% or more of the total outstanding shares
of BioShield common stock. In addition, BioShield stockholders are entitled to
review on five (5) days' written notice the following:

         -        the articles of incorporation;

         -        the bylaws;

         -        resolutions increasing or decreasing the number of directors
                  and the names and addresses of all members of the board of
                  directors;

         -        resolutions creating one or more classes or series of shares;

         -        the minutes of all stockholders' meetings, executed waivers of
                  notice of meetings and executed written consents evidencing
                  all action taken by stockholders without a meeting for the
                  past three years;

         -        all written communications to stockholders generally within
                  the past three years, including the financial statements
                  furnished for the past three years;

         -        a list of the names and addresses of the corporation's current
                  directors and officers; and

         -        the corporation's most recent annual registration delivered to
                  the Secretary of State of Georgia.


DIVIDENDS AND OTHER DISTRIBUTIONS

         Holders of AHT common stock are entitled to receive dividends as may be
declared by the AHT board of directors, in accordance with the limitations of
Delaware law. Delaware law generally allows AHT to declare and pay dividends out
of the excess, if any, of total assets less total liabilities over capital. AHT
has not paid any dividends on its outstanding common stock to date.

         BioShield may authorize or declare dividends in accordance with Georgia
law. Under Georgia law, no distribution generally will be made, if, as a result,
BioShield would not be able to pay its debts as they become due in the usual
course of business. BioShield has not paid any dividends on its outstanding
common stock to date.


APPRAISAL RIGHTS OF DISSENTING STOCKHOLDERS

         Under Delaware law, stockholders of AHT are entitled to demand
appraisal of their shares and have the Delaware Court of Chancery determine
their fair value when AHT is a party to some kinds of mergers or consolidations.
However, this right to demand appraisal does not generally apply to stockholders
if a vote of the stockholders of AHT is not necessary to authorize the merger or
consolidation. You must follow the procedures described in the Delaware law to
properly assert your appraisal rights. A copy of the Delaware law relating to
appraisal rights has been provided for your convenience as Appendix Q.


                                      101
<PAGE>   114

         Under Georgia law, a stockholder of BioShield is entitled to dissent
from, and obtain payment of the fair value of his shares in the event of:

         -        consummation of some kinds of plans of merger to which the
                  corporation is a party;

         -        consummation of a plan of share exchange to which the
                  corporation is a party, if the stockholder is entitled to vote
                  on the plan;

         -        consummation of a sale or exchange of all or substantially all
                  of the property of the corporation if a stockholder vote is
                  required on the sale or exchange; or

         -        an amendment of the articles of incorporation that materially
                  and adversely affects rights in respect of a dissenter's
                  shares.


PREEMPTIVE RIGHTS

         Neither BioShield nor AHT common stockholders have preemptive rights.


ABSENCE OF RIGHTS PLANS

         Neither AHT nor BioShield have any rights plans outstanding.


STATE ANTITAKEOVER STATUTES

         AHT is governed by the antitakeover provisions of the Delaware General
Corporation Law. Generally, this law prevents any stockholder with 15% or more
of AHT's outstanding common stock, except who has owned these shares since
December 23, 1987, from engaging in a any kind of business combination,
including a merger, with AHT for three years after that person acquired their
shares. Under Delaware law, an AHT stockholder who holds more than 15% of the
outstanding AHT common stock can avoid the three-year moratorium if:

         -        the AHT board of directors approves either the business
                  combination or the transaction in which the stockholder
                  acquired their 15% interest in AHT common stock before the
                  stockholder acquires the shares of AHT common stock;

         -        the stockholder owns at least 85% of the AHT's outstanding
                  common stock, excluding shares held by directors who are also
                  officers of AHT and by some employee stock ownership plans; or

         -        the business combination is approved by the AHT board of
                  directors and authorized by the affirmative vote of the
                  holders of at least 66 2/3% of the outstanding AHT common
                  stock not already owned by the stockholder who wants to do a
                  business combination with AHT.

         Under Georgia law, BioShield may not engage in any business
combination, including a merger, with any person who owns 10% or more of the
voting stock of BioShield or under some circumstances, who is an affiliate of
the corporation, unless the stockholder owns at least 90% of the outstanding
voting stock BioShield, excluding shares owned by directors, officers,
subsidiaries of BioShield and any employee stock plan.


TRANSACTIONS WITH INTERESTED DIRECTORS

         Under Delaware law, some transactions between AHT and its directors or
officers are not void or voidable solely because of the officer's or director's
interest, because the officer or director was present at a board or committee
meeting at which the contract or transaction was authorized or because the
director's vote was counted for that purpose, if:


                                      102
<PAGE>   115

         -        the material facts relating to the director's or officer's
                  interest are disclosed the AHT board of directors and a
                  majority of disinterested directors approves the contract or
                  transaction;

         -        the material facts relating to the director's or officer's
                  interest are disclosed or known to the stockholders entitled
                  to vote, and the contract or transaction is approved by a
                  majority of the outstanding shares of AHT common stock; or

         -        the contract or transaction was fair to the corporation at the
                  time it was approved.

         Under Georgia law, transactions between BioShield and its directors or
officers may not give rise to lawsuits by stockholders of BioShield simply
because the transaction was an interested transaction if:

         -        a majority of disinterested directors approved the
                  transaction;

         -        holders of a majority of the outstanding shares of BioShield
                  common stock approved the transaction; or

         -        the transaction was fair to BioShield at the time it was
                  approved.

Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of

"Company").

                                  INTRODUCTION

     The Board of Directors of each of Parent, Merger Subsidiary and the Company
have unanimously approved and deem it advisable and in the best interests of
their respective companies and stockholders of each of the Company, Parent and
Merger Subsidiary to enter into a business combination;

     In furtherance of such acquisition, it is proposed that Merger Subsidiary
shall be merged with and into the Company (the "Merger"), in accordance with the
terms and subject to the conditions provided in this Agreement;

     The parties to this Agreement intend that the Merger qualify as a
"reorganization" within the meaning of Section 368(a) of the Internal Revenue
Code of 1986, as amended (the "Code"), and the rules and regulations promulgated
thereunder, and that this Agreement constitutes a plan of reorganization;

     The Boards of Directors of each of Parent and the Company have approved
this Agreement and the Merger in accordance with the laws of their respective
states of incorporation and upon the terms and conditions set forth herein; and

     Parent, Merger Subsidiary and the Company desire to make certain
representations, warranties, covenants and agreements in connection with the
Merger and the other transactions contemplated by this Agreement and also to
prescribe various conditions to the Merger and the other transactions

the parties shall cause a certificate of merger (the "Certificate of Merger") to

Time and without any further action on the part of the Company or Parent: (a)

                                       A-2
<PAGE>   122

          (b) CANCELLATION OF TREASURY STOCK AND PARENT-OWNED STOCK.  Each share
     of Company Common Stock held in the treasury of the Company or owned by any
     subsidiary of the Company immediately prior to the Effective Time and each
     share of Company Common Stock that is owned by Parent, Merger Subsidiary or
     any other subsidiary of Parent immediately prior to the Effective Time
     shall automatically be canceled and retired and shall cease to exist, and
     no consideration shall be delivered in exchange therefor.

          (c) CONVERSION OF COMPANY COMMON STOCK.  Subject to Section 2.2(f),
     each issued and outstanding share of Company Common Stock immediately prior
     to the Effective Time (other than shares to be canceled in accordance with
     Section 2.1(b) or Dissenting Shares (as hereinafter defined) shall be
     converted into, and become exchangeable for, the right to receive such
     number of fully paid and nonassessable shares of common stock, no par
     value, of Parent (the "Parent Common Stock") as is equal to the Exchange
     Ratio, as defined in Section 3.1 (the "Merger Consideration"). At the
     Effective Time, all such shares of Company Common Stock, when so converted,
     shall no longer be outstanding and shall automatically be canceled and
     retired and shall cease to exist, and each holder of a certificate
     representing any such shares of Company Common Stock shall cease to have
     any rights with respect thereto, except the right to receive the Merger
     Consideration and any cash in lieu of fractional shares of Parent Common
     Stock to be issued in exchange therefor upon surrender of such certificate
     in accordance with Section 2.2(f) and any dividends or other distributions
     to which such holder is entitled pursuant to Section 2.2(c), in each case,
     without interest.

     Section 2.2 EXCHANGE OF CERTIFICATES.

     (a) EXCHANGE AGENT.  As of the Effective Time, Parent shall enter into an
agreement with such bank or trust company as may be designated by Parent, and
reasonably acceptable to the Company (the "Exchange Agent"), which shall provide
that Parent shall deposit with the Exchange Agent as of the Effective Time, for
the benefit of the holders of shares of Company Common Stock, for exchange in
accordance with this Article II, through the Exchange Agent, certificates
representing the shares of Parent Common Stock (such shares of Parent Common
Stock, together with any dividends or distributions with respect thereto with a
record date after the Effective Time, any Excess Shares (as defined in Section
2.2(f)) and any cash (including cash proceeds from the sale of the Excess
Shares) payable in lieu of any fractional shares of Parent Common Stock being
hereinafter referred to as the "Exchange Fund") issuable or payable pursuant to
Section 2.1 in exchange for outstanding shares of Company Common Stock. For
purposes of determining the number of shares of Parent Common Stock that Parent
shall deposit with the Exchange Agent, Parent shall assume that no holder of
shares of Company Common Stock will perfect such holder's right to appraisal of
such holder's shares of Company Common Stock.

     (b) EXCHANGE PROCEDURE.  Promptly after the Effective Time, Parent shall
cause the Exchange Agent to mail to each holder of record of a certificate or
certificates which immediately prior to the Effective Time represented
outstanding shares of Company Common Stock (the "Certificates") whose shares
were converted into the right to receive the Merger Consideration pursuant to
Section 2.1, (i) a letter of transmittal (which shall specify that delivery
shall be effected, and risk of loss and title to the Certificates shall pass,
only upon delivery of the Certificates (or affidavits of loss in lieu thereof)
to the Exchange Agent and shall be in such form and have such other provisions
as Parent may

                                       A-3
<PAGE>   123

reasonably specify) and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for the Merger Consideration. Upon surrender of a
Certificate for cancellation to the Exchange Agent, together with such letter of
transmittal, duly executed, and such other documents as may reasonably be
required by the Exchange Agent, the holder of such Certificate shall be entitled
to receive in exchange therefor the Merger Consideration into which the shares
of Company Common Stock shall have been converted pursuant to Section 2.1, cash
in lieu of fractional shares of Parent Common Stock to which such holder is
entitled pursuant to Section 2.2(f) and any dividends or other distributions to
which such holder is entitled pursuant to Section 2.2(c), and the Certificate so
surrendered shall be canceled. In the event of a transfer of ownership of
Company Common Stock which is not registered in the transfer records of the
Company, payment of Merger Consideration may be made to a person other than the
person in whose name the Certificate so surrendered is registered, if such
Certificate shall be properly endorsed or otherwise be in proper form for
transfer and the person requesting such Merger Consideration shall pay any
transfer or other taxes required by reason of the payment to a person other than
the registered holder of such Certificate or establish to the satisfaction of
the Surviving Corporation that such tax has been paid or is not applicable.

     (c) DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES.  No dividends or
other distributions with respect to Parent Common Stock with a record date after
the Effective Time shall be paid to the holder of any unsurrendered Certificate
with respect to the shares of Parent Common Stock represented thereby, and no
cash payment in lieu of fractional shares shall be paid to any such holder
pursuant to Section 2.2(f), in each case until the surrender of such Certificate
in accordance with this Article II. Subject to the effect of applicable escheat
laws, following surrender of any such Certificate, there shall be paid to the
holder of the certificate representing whole shares of Parent Common Stock
issued in exchange therefor, without interest, (i) at the time of such
surrender, the amount of any cash payable in lieu of a fractional share of
Parent Common Stock to which such holder is entitled pursuant to Section 2.2(f)
and the amount of dividends or other distributions with a record date after the
Effective Time theretofore paid with respect to such whole shares of Parent
Common Stock and (ii) at the appropriate payment date, the amount of dividends
or other distributions with a record date after the Effective Time but prior to
such surrender and with a payment date subsequent to such surrender payable with
respect to such whole shares of Parent Common Stock.

     (d) NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK.  All Merger
Consideration paid upon the surrender of Certificates in accordance with the
terms of this Article II (including any cash paid pursuant to Section 2.2(f))
shall be deemed to have been paid in full satisfaction of all rights pertaining
to the shares of Company Common Stock represented by such Certificates, except
as otherwise provided herein or by applicable law, and there shall be no further
registration of transfers on the stock transfer books of the Surviving
Corporation of the shares of Company Common Stock which were outstanding
immediately prior to the Effective Time. If, after the Effective Time,
Certificates are presented to the Surviving Corporation for any reason, they
shall be canceled and exchanged as provided in this Article II.

     (e) TERMINATION OF EXCHANGE FUND; NO LIABILITY.  Any portion of the
Exchange Fund which remains undistributed to the holders of the Certificates for
twelve months after the Effective Time shall be delivered to Parent, upon demand
by Parent, and any holders of the Certificates who have not theretofore complied
with this Article II shall thereafter look only to Parent for payment of their
claim for Merger Consideration, any dividends or

                                       A-4
<PAGE>   124

distributions with respect to Parent Common Stock and any cash in lieu of
fractional shares of Parent Common Stock. None of Parent, Merger Subsidiary, the
Company or the Exchange Agent shall be liable to any person in respect of any
shares of Parent Common Stock, any dividends or distributions with respect
thereto, any cash in lieu of fractional shares of Parent Common Stock or any
cash from the Exchange Fund, in each case delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law. If any
Certificate shall not have been surrendered immediately prior to such date on
which any amounts payable pursuant to this Article II would otherwise escheat to
or become the property of any Governmental Entity (as defined in Section
4.1(d)), any such amounts shall, to the extent permitted by applicable escheat
law, become the property of the Surviving Corporation, free and clear of all
claims or interest of any person previously entitled thereto. Any portion of the
Merger Consideration deposited in the Exchange Fund pursuant to this Section 2.2
in consideration of Dissenting Shares, if any, have been perfected shall be
returned to Parent, upon demand by Parent.

     (f) NO FRACTIONAL SHARES.  (i) No certificates or scrip representing
fractional shares of Parent Common Stock shall be issued upon the surrender for
exchange of Certificates pursuant to this Article II, no dividend or
distribution of Parent shall relate to such fractional share interests and such
fractional share interests will not entitle the owner thereof to vote or to any
rights of a stockholder of Parent.

             (ii) As promptly as practicable following the Effective Time, the
        Exchange Agent shall determine the excess of (A) the number of whole
        shares of Parent Common Stock delivered to the Exchange Agent by Parent
        pursuant to Section 2.2(a) minus (B) the aggregate number of whole
        shares of Parent Common Stock to be distributed to former holders of
        Company Common Stock pursuant to Section 2.2(b) (such excess being
        herein called the "Excess Shares"). Following the Effective Time, the
        Exchange Agent shall, on behalf of former holders of Company Common
        Stock, sell the Excess Shares at then-prevailing prices, and in round
        lots to the extent practicable. The Exchange Agent shall use reasonable
        efforts to complete the sale of the Excess Shares as promptly following
        the Effective Time as, in the Exchange Agent's sole judgment, is
        practicable consistent with obtaining the best execution of such sales
        in light of prevailing market conditions, but in no event later than ten
        (10) business days after the Effective Time. Until the net proceeds of
        such sale or sales have been distributed to the holders of Certificates
        formerly representing Company Common Stock, the Exchange Agent shall
        hold such proceeds in trust for such holders (the "Common Shares
        Trust"). The Surviving Corporation shall pay all commissions, transfer
        taxes and other out-of-pocket transaction costs, including the expenses
        and compensation of the Exchange Agent, incurred in connection with such
        sale of the Excess Shares and maintenance of the Common Shares Trust.
        The Exchange Agent shall determine the portion of the Common Shares
        Trust to which each former holder of Company Common Stock is entitled,
        if any, by multiplying the amount of the aggregate net proceeds
        comprising the Common Shares Trust by a fraction, the numerator of which
        is the amount of the fractional share interest to which such former
        holder of Company Common Stock is entitled (after taking into account
        all shares of Company Common Stock held at the Effective Time by such
        holder) and the denominator of which is the aggregate amount of
        fractional share interests to which all former holders of Company Common
        Stock are entitled.

                                       A-5
<PAGE>   125

             (iii) Notwithstanding the provisions of Section 2.2(f)(ii), Parent
        may elect at its option, exercised prior to the Effective Time, in lieu
        of the issuance and sale of Excess Shares and the making of the payments
        hereinabove contemplated, to pay each former holder of Company Common
        Stock an amount in cash equal to the product obtained by multiplying (A)
        the fractional share interest to which such former holder (after taking
        into account all shares of Company Common Stock held at the Effective
        Time by such holder) would otherwise be entitled by (B) the Average
        Closing Bid Price (as hereinafter defined), and, in such case, all
        references herein to the cash proceeds of the sale of the Excess Shares
        and similar references shall be deemed to mean and refer to the payments
        calculated as set forth in this Section 2.2(f)(iii).

             (iv) As soon as practicable after the determination of the amount
        of cash, if any, to be paid to holders of Certificates formerly
        representing Company Common Stock with respect to any fractional share
        interests, but in no event later than three (3) business days after such
        determination, the Exchange Agent shall make available such amounts to
        such holders of Certificates formerly representing Company Common Stock
        subject to and in accordance with the terms of Section 2.2(c).

     (g) INVESTMENT OF EXCHANGE FUND.  The Exchange Agent shall invest any cash
included in the Exchange Fund, as reasonably directed by Parent, on a daily
basis in reasonably prudent investments. Any interest and other income resulting
from such investments shall be paid to the Surviving Corporation.

     (h) LOST CERTIFICATES.  If any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such Certificate to be lost, stolen or destroyed and, if required by Parent, the
posting by such person of a bond in such reasonable amount as Parent may direct
as indemnity against any claim that may be made against it with respect to such
Certificate, the Exchange Agent shall issue in exchange for such lost, stolen or
destroyed Certificate the applicable Merger Consideration with respect thereto
and, if applicable, any unpaid dividends and distributions on shares of Parent
Common Stock deliverable in respect thereof and any cash in lieu of fractional
shares, in each case pursuant to this Agreement.

     Section 2.3 DISSENTING SHARES.  Notwithstanding Section 2.1(c), shares of
Company Common Stock outstanding immediately prior to the Effective Time and
held by a holder who has demanded and perfected their appraisal rights for such
shares of Company Common Stock in accordance with Delaware Law (such shares
being referred to herein as "Dissenting Shares") shall not be converted into a
right to receive the Merger Consideration, unless such holder fails to perfect
or withdraws or otherwise loses his right to appraisal. If after the Effective
Time such holder fails to perfect or withdraws or loses his right to appraisal,
such shares of Company Common Stock shall be treated as if they had been
converted as of the Effective Time into a right to receive the Merger
Consideration. The Company shall give Parent prompt notice of any demands
received by the Company for appraisal of shares of Company Common Stock, and
Parent shall have the right to participate in all negotiations and proceedings
with respect to such demands. The Company shall not, except with the prior
written consent of Parent, make any payment with respect to, or settle or offer
to settle, any such demands.

     Section 2.4 COMPANY OPTIONS.  (a) At the Effective Time, each outstanding
option to purchase Company Common Stock (an "Option") shall be deemed to
constitute an

                                       A-6
<PAGE>   126

option to acquire, on the same terms and conditions as were applicable under
such Option, the same number of shares of Parent Common Stock as the holder of
such Option would have been entitled to receive pursuant to the Merger had such
holder exercised such option in full immediately prior to the Effective Time
(rounded down to the nearest whole number), at a price per share (rounded up to
the nearest whole cent) equal to (y) the aggregate exercise price for the
Company Common Stock otherwise purchasable pursuant to such Option divided by
(z) the number of full shares of Parent Common Stock deemed purchasable pursuant
to such Option in accordance with the foregoing; provided, however, that in the
case of any Option to which Section 422 of the Code applies, the option price,
the number of shares purchasable pursuant to such option and the terms and
conditions of exercise of such option shall be determined in accordance with the
foregoing, subject to such adjustments as are necessary in order to satisfy the
requirements of Section 424(a) of the Code.

     (b) At or prior to the Effective Time, the Company shall make all necessary
arrangements with respect to the Stock Plans (as hereinafter defined) to permit
the assumption of the unexercised Options by Parent pursuant to this Section.
Effective at the Effective Time, Parent shall assume each Option in accordance
with the terms of the Stock Plan under which it was issued and the stock option
agreement by which it is evidenced. At or prior to the Effective Time, Parent
shall take all corporate action necessary to reserve for issuance a sufficient
number of shares of Parent Common Stock for delivery upon exercise of Options
assumed by it in accordance with this Section. As soon as practicable after the
Effective Time, Parent shall file a registration statement on Form S-3 or Form
S-8, as the case may be (or any successor or other appropriate forms), or
another appropriate form with respect to the Parent Common Stock subject to such
Options, and shall use its best efforts to maintain the effectiveness of such
registration statement (and maintain the current status of the prospectus or
prospectuses contained therein) for so long as such Options remain outstanding.

     (c) As soon as practicable after the consummation of the Merger, Parent
shall deliver to the holders of options to acquire Parent Common Stock ("Parent
Options") appropriate notices setting forth such holders' rights pursuant to the
respective Stock Plans.

                                  ARTICLE III

                                 EXCHANGE RATIO

     Section 3.1 EXCHANGE RATIO.  (a) For purposes of this Agreement, "Exchange
Ratio" shall mean the quotient determined by dividing $1.75 by the Average
Closing Bid Price, as hereinafter defined, calculated to the nearest hundred
thousandth (i.e., five decimal places (.xxxxx)), but in no event shall such
Exchange Ratio exceed .29167 (representing an Average Closing Bid Price of $6)
nor be less than .09722 (representing an Average Closing Bid Price of $18). The
"Average Closing Bid Price" shall mean that price which shall be computed as the
arithmetic average of the Closing Bid Prices, as hereinafter defined, for a
share of Parent Common Stock for the ten (10) consecutive trading days ending on
the third trading day prior to the date of the later to occur of the Company
Stockholders Meeting (as hereinafter defined) and the Parent Stockholders
Meeting (as hereinafter defined), and "Closing Bid Price" shall mean, for any
trading day, the last closing bid price on the Nasdaq SmallCap Market (the
"Nasdaq-SM") as reported by Bloomberg Financial Markets ("Bloomberg"), or, if
the Nasdaq-SM is not the principal trading market for the Parent Common Stock,
the last closing bid price for the Parent

                                       A-7
<PAGE>   127

Common Stock on the principal securities exchange or trading market where such
security is listed or traded as reported by Bloomberg, or if the foregoing do
not apply, the last closing bid price of such security in the over-the-counter
market on the pink sheets or bulletin board for such security as reported by
Bloomberg, or, if no closing bid price is reported for such security by
Bloomberg, the last closing trade price of such security as reported by
Bloomberg.

     (b) ADJUSTMENT OF EXCHANGE RATIO.  In the event Parent changes (or
establishes a record date for changing) the number of shares of Parent Common
Stock issued and outstanding prior to the Effective Time as a result of a stock
split, stock dividend, recapitalization, subdivision, reclassification,
combination, merger, exchange of shares or other similar transaction with
respect to the outstanding Parent Common Stock and the record date therefor
shall be prior to the Effective Time, the Exchange Ratio and the Parent stock
prices for determining any adjustments thereto and calculations thereof shall be
proportionately adjusted to reflect such stock split, stock dividend,
recapitalization, subdivision, reclassification, combination, merger, exchange
of shares or other similar transaction.

                                   ARTICLE IV

                         REPRESENTATIONS AND WARRANTIES

     Section 4.1 REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  Except as set
forth in the Company SEC Documents (as hereinafter defined) or in the disclosure
schedule delivered by the Company to Parent and Merger Subsidiary prior to the
execution of this Agreement (the "Company Disclosure Schedule"), the Company
represents and warrants to Parent and Merger Subsidiary as follows:

          (a) ORGANIZATION, STANDING AND CORPORATE POWER.  Each of the Company
     and its Significant Subsidiaries (as hereinafter defined) is a corporation
     or other legal entity duly organized, validly existing and in good standing
     under the laws of the jurisdiction in which it is organized and has all
     requisite corporate or other power and authority, as the case may be, to
     own and operate its properties and to carry on its business as now being
     conducted. Each of the Company and its Significant Subsidiaries (as
     hereinafter defined) is duly qualified or licensed to do business and is in
     good standing in each jurisdiction in which the nature of its business or
     the ownership or leasing of its properties makes such qualification or
     licensing necessary, except where the failure to be so qualified, licensed
     or in good standing (individually or in the aggregate) could not reasonably
     be expected to have a Company Material Adverse Effect. For purposes of this
     Agreement, "Company Material Adverse Effect" means any change, effect,
     event, occurrence, state of facts or development that is materially adverse
     to the business, financial condition or results of operations of the
     Company and its Subsidiaries (as hereinafter defined), taking the Company
     and its Subsidiaries together as a whole; provided, however, that none of
     the following shall be deemed in themselves, either alone or in
     combination, to constitute a Company Material Adverse Effect: (a) any
     change in the market price or trading volume of the Company Common Stock
     after the date hereof or (b) any adverse change, effect, event, occurrence,
     state of facts or development relating to (i) the announcement or pendency
     of the transactions contemplated by this Agreement, (ii) conditions
     affecting the industries in which the Company participates or the U.S.
     economy as a whole, (iii) out-of-pocket fees and expenses (including legal,
     accounting, investment

     this Agreement. For purposes of this Agreement, a "Subsidiary" means with
     respect to a Person, any entity, whether incorporated or unincorporated, of
     which at least a majority of the securities or ownership interests having
     by their terms ordinary voting power to elect a majority of the board of
     directors or other persons performing similar functions is directly or
     indirectly owned or controlled by such Person or by one or more of its
     respective Subsidiaries or by such Person and one or more of its respective
     Subsidiaries; a "Person" means an individual, corporation, partnership,
     limited liability company, joint venture, association, trust,
     unincorporated organization or other entity; and a "Significant Subsidiary"
     means any direct or indirect subsidiary of the Company that has annual
     revenues or total assets of at least $50,000.

          (b) SUBSIDIARIES.  Section 4.1(b) of the Company Disclosure Schedule
     lists each subsidiary of the Company and its respective jurisdiction of
     incorporation and indicates whether such subsidiary is a Significant
     Subsidiary. All the outstanding shares of capital stock of each Significant
     Subsidiary have been validly issued and are fully paid and nonassessable
     and are owned by the Company, by another subsidiary of the Company or by
     the Company and another such subsidiary, free and clear of all pledges,
     claims, liens, encumbrances and security interests of any kind or nature
     whatsoever (collectively, "Liens"). Except for the capital stock of its
     Subsidiaries, the Company does not own, directly or indirectly, any capital
     stock or other ownership interest in any person.

          (c) CAPITAL STRUCTURE.  Except as set forth in Section 4.1(c) of the
     Company Disclosure Schedule, at the time of execution of this Agreement, no
     shares of capital stock or other voting securities of the Company are
     issued, reserved for issuance or outstanding. All outstanding shares of
     capital stock of the Company are duly authorized, validly issued, fully
     paid and nonassessable and not subject to preemptive rights. There are no
     outstanding bonds, debentures, notes or other indebtedness of the Company
     having the right to vote (or convertible into, or exchangeable for,
     securities having the right to vote) on any matters on which holders of
     Company Common Stock may vote. Except as set forth in Section 4.1(c) of the
     Company Disclosure Schedule, there are no outstanding options, warrants,
     calls, rights, commitments, agreements or undertakings of any kind to which
     the Company or any of its Significant Subsidiaries is a party or by which
     any of them is bound obligating the Company or any of its Significant
     Subsidiaries to issue, deliver or sell, or cause to be issued, delivered or
     sold, additional shares of capital stock or other voting securities of the
     Company or of any of its Significant Subsidiaries or obligating the Company
     or any of its Significant Subsidiaries to issue, grant, extend or enter
     into any such option, warrant, call, right, commitment, agreement, or
     undertaking. There are no outstanding rights, commitments, agreements, or
     undertakings of any kind obligating the Company or any of its Significant
     Subsidiaries to repurchase, redeem or otherwise acquire any

     of the date of this Agreement and the exercise price of each outstanding
     option.

          (d) AUTHORITY; NONCONTRAVENTION.  The Company has the requisite
     corporate power and authority to enter into this Agreement and, subject to
     the approval of this Agreement by the affirmative votes of holders of a
     majority of the outstanding shares of Company Common Stock (the "Company
     Shareholder Vote") with respect to the Merger, to execute, deliver and
     perform its obligations under this Agreement and to consummate the
     transactions contemplated hereby. This Agreement has been duly executed and
     delivered by the Company and constitutes a valid and binding obligation of
     the Company, enforceable against the Company in accordance with its terms,
     subject to bankruptcy, insolvency, fraudulent transfer, reorganization,
     moratorium and similar laws of general applicability relating to or
     affecting creditors' rights and to general equity principles. The execution
     and delivery of this Agreement do not, and the consummation of the
     transactions contemplated by this Agreement and compliance with the
     provisions of this Agreement will not, result in (i) a breach or violation
     of, or a default (with or without notice or lapse of time, or both) under,
     the certificate of incorporation or by-laws of the Company or the
     comparable charter or organizational documents of any of its Significant
     Subsidiaries, (ii) a breach or violation of, or a default (with or without
     notice or lapse of time, or both) under, any loan or credit agreement,
     note, bond, mortgage, indenture, lease or other agreement, instrument or
     license applicable to the Company or any of its Significant Subsidiaries or
     their respective properties or assets or (iii) subject to the governmental
     filings and other matters referred to in the following sentence, a breach
     or violation of, or a default (with or without notice or lapse of time, or
     both) under, any judgment, order, decree, statute, law, ordinance, rule or
     regulation applicable to the Company or any of its Significant Subsidiaries
     or their respective properties or assets, other than, in the case of
     clauses (ii) and (iii), any such breaches, violations or defaults that
     individually or in the aggregate could not reasonably be expected to (x)
     have a Company Material Adverse Effect, (y) materially impair the Company's
     ability to perform its obligations under this Agreement or (z) prevent or
     materially delay the consummation of the transactions contemplated by this
     Agreement. No consent, approval, order or authorization of, or
     registration, declaration or filing with or exemption by (collectively,
     "Consents") any Federal, state or local government or any court,
     administrative or regulatory agency or commission or other governmental
     authority or agency, domestic or foreign (a "Governmental Entity"), is
     required by or with respect to the Company or any of its Significant
     Subsidiaries in connection with the execution and delivery of this
     Agreement by the Company or the consummation by the Company of the
     transactions contemplated by this Agreement, except for (i) the filing with
     the United States Securities and Exchange Commission (the "SEC") of (A) the
     Joint Proxy Statement (as defined in Section 7.1(a)), and (B) such reports
     under the Securities Exchange Act of 1934, as amended (the "Exchange Act")
     and the Securities Act of 1933, as amended (the "Securities Act"), as may
     be required in connection with this Agreement and the transactions
     contemplated hereby, (ii) such filings as may be required under state

     of other states in which the Company is qualified to do business, and (iv)
     such other consents, approvals, orders, authorizations, registrations,
     declarations and filings, the failure of which to be made or obtained
     individually or in the aggregate could not reasonably be expected to (x)
     have a Company Material Adverse Effect, (y) materially impair the Company's
     ability to perform its obligations under this Agreement or (z) prevent or
     materially delay the consummation of the transactions contemplated by this
     Agreement.

          (e) SEC DOCUMENTS; FINANCIAL STATEMENTS; NO UNDISCLOSED
     LIABILITIES.  The Company has filed all required reports, schedules, forms,
     statements and other documents with the SEC since January 1, 1998 (the
     "Company SEC Documents"). As of their respective dates, the Company SEC
     Documents complied in all material respects with the requirements of the
     Securities Act or the Exchange Act, as the case may be, and the rules and
     regulations of the SEC promulgated thereunder applicable to such Company
     SEC Documents, and none of the Company SEC Documents when filed contained
     any untrue statement of a material fact or omitted 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 consolidated financial statements of the Company included
     in the Company SEC Documents as of their respective dates comply as to form
     in all material respects with applicable accounting requirements and the
     published rules and regulations of the SEC with respect thereto, have been
     prepared in accordance with generally accepted accounting principles
     (except, in the case of unaudited statements, as permitted by Form 10-Q of
     the SEC) applied on a consistent basis during the periods involved (except
     as may be indicated in the notes thereto) and fairly present in all
     material respects the consolidated financial position of the Company and
     its consolidated Subsidiaries as of the dates thereof and the consolidated
     results of their operations and cash flows for the periods then ended
     (subject, in the case of unaudited statements, to normal and recurring
     year-end audit adjustments). Except as reflected in the financial
     statements of the Company included in the Company SEC Documents, neither
     the Company nor any of its Subsidiaries has any liabilities or obligations
     of any nature (whether accrued, absolute, contingent or otherwise) which
     are required by generally accepted accounting principles to be set forth on
     a consolidated balance sheet of the Company and its consolidated
     Subsidiaries or in the notes thereto other than any liabilities and
     obligations incurred since March 31, 2000 in the ordinary course of
     business or which, individually or in the aggregate, could not reasonably
     be expected to have a Company Material Adverse Effect.

          (f) ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as disclosed in
     Section 4.1(f) of the Company Disclosure Schedule and except as expressly
     contemplated by this Agreement, since March 31, 2000, the Company and its
     Significant Subsidiaries have conducted their business only in the ordinary
     course consistent with past practice, and there has not been (i) any change
     in the financial condition, properties, business or results of operations
     of the Company or its Subsidiaries or any development or combination of
     developments of which management of the Company has, or should reasonably
     have, knowledge that, individually or in the aggregate, has had or is
     reasonably likely to have a Company Material Adverse Effect, (ii) any
     declaration, setting aside or payment of any dividend or other distribution
     (whether in cash, stock or property) with respect to any of the Company's
     capital stock, (iii) (A) any granting by the Company or any of its
     Significant Subsidiaries to any current

     Significant Subsidiaries of any material increase in compensation or

     except in the ordinary course of business consistent with past practice or
     as was required under employment agreements in effect as of March 31, 2000,
     (B) any granting by the Company or any of its Significant Subsidiaries to
     any such director, officer or employee of the Company or any of its
     Significant Subsidiaries of any material increase in severance or
     termination pay (including the acceleration in the exercisability of
     options to purchase, or in the vesting of, Company Common Stock (or other
     property)), except as was required under employment, severance or
     termination agreements or plans in effect as of March 31, 2000, or (C) any
     entry by the Company or any of its Subsidiaries into any material
     employment, deferred compensation, severance or termination agreement with
     any such current or former director, officer or employee, (iv) any material
     damage, destruction or other casualty loss, whether or not covered by
     insurance, with respect to any material asset or property owned, leased or
     otherwise used by the Company or any Significant Subsidiary that has had or
     could reasonably be expected to have a Company Material Adverse Effect, (v)

     term of any outstanding security of the Company or any Significant
     Subsidiary, (vii) any incurrence, assumption or guarantee by the Company or

     creation or assumption by the Company or any of its Significant
     Subsidiaries of any Lien on any asset other than in the ordinary course of
     business consistent with past practice, but in no event in the amount of
     more than $25,000 for any one transaction or $100,000 in the aggregate,

     business consistent with past practice and (B) investments made in
     accordance with the Company's investment guidelines, a copy of which has
     been made available to Parent, and in the ordinary course of business
     consistent with past practice, (x) any transaction or commitment made, or
     any contract or agreement entered into, by the Company or any of its
     Significant Subsidiaries relating to its assets or business (including the
     acquisition or disposition of any assets or the merger o r consolidation
     with any person) or any relinquishment by the Company or any of its
     Significant Subsidiaries of any contract or other right, in either case,
     material to the Company and its Subsidiaries taken as a whole, other than
     transactions and commitments in the ordinary course of business consistent
     with past practice and those contemplated by this Agreement, but in the
     case of transactions or commitments outside of the ordinary course of
     business in no event representing commitments on behalf of the Company or
     any of its Subsidiaries of more than $50,000 for any transaction and
     $200,000 for any series of transactions, (xi) except as set forth in
     Section 4.1(f) of the Company Disclosure Schedule, as of the date hereof,

     of licenses or changing the basis of pricing, (xii) any material labor
     dispute, other than routine individual grievances, or any activity or

                                      A-12
<PAGE>   132

     Subsidiaries, which employees were not subject to a collective bargaining
     agreement at March 31, 2000, or any material lockouts, strikes, slowdowns,
     work stoppages or threats thereof by or with respect to such employees or
     (xiii) any material agreement, commitment, arrangement or undertaking by
     the Company or any of its Subsidiaries to perform any action described in
     clauses (i) through (xii) above.

          (g) LITIGATION; INSURANCE.  (i) Except as disclosed in the Company SEC
     Documents or in Section 4.1(g) of the Company Disclosure Schedule, there is
     no suit, action or proceeding pending or, to the knowledge of the
     management of the Company, threatened against or affecting the Company or
     any of its Significant Subsidiaries (and the Company is not aware of any
     basis for any such suit, action or proceeding) that, individually or in the
     aggregate, could reasonably be expected to (A) have a Company Material
     Adverse Effect, (B) impair the ability of the Company to perform its
     obligations under this Agreement or (C) prevent or materially delay the
     consummation of any of the transactions contemplated by this Agreement, nor
     is there any judgment, decree, injunction, rule or order of any
     Governmental Entity or arbitrator outstanding against the Company or any of
     its Significant Subsidiaries having, or which could reasonably be expected
     to have, any such effect. Section 4.1(g)(i) of the Company Disclosure
     Schedule sets forth, with respect to any pending suit, action or proceeding
     to which the Company or any its Significant Subsidiaries is a party and
     which involves claims which if adversely determined would exceed $50,000,
     inclusive of any attorney's fees, interest and punitive damages, the forum,
     the parties thereto, the subject matter thereof and the amount of damages
     claimed.

             (ii) As of the date hereof, (A) the Company's directors' and
        officers' liability insurance and indemnification policy for the period
        beginning December 7, 1999 through December 7, 2000 (the "2000 Policy")
        is in full force and effect; (B) the insurance company which has
        underwritten the Company's directors' and officers' liability insurance
        and indemnification policies is continuing to defend the actions set
        forth in Section 4.1(g)(ii) of the Company Disclosure Schedule; and
        (iii) there have not been any claims made against the Company's
        directors and officers which would be covered by the 2000 Policy.

          (h) ABSENCE OF CHANGES IN STOCK AND BENEFIT PLANS.  Except as
     disclosed in Section 4.1(f) and (h) of the Company Disclosure Schedule or
     as expressly permitted by this Agreement, since March 31, 2000, there has
     not been (i) any acceleration, amendment or change of the period of
     exercisability or vesting of any company options or restricted stock, stock
     bonus or other awards under the Stock Plans (including any discretionary
     acceleration of the exercise periods or vesting by the Company's Board of
     Directors or any committee thereof or any other persons administering a
     Stock Plan) or authorization of cash payments in exchange for any company
     options, restricted stock, stock bonus or other awards granted under any of
     such Stock Plans or (ii) any adoption or amendment by the Company or any of
     its Significant Subsidiaries of any collective bargaining agreement or any
     bonus, pension, profit sharing, deferred compensation, incentive
     compensation, stock ownership, stock purchase, stock option, phantom stock,
     stock appreciation right, retirement, vacation, severance, disability,
     death benefit, hospitalization, medical, workers' compensation,
     supplementary unemployment benefits or other plan, arrangement or
     understanding (whether or not legally binding) providing benefits to any
     current or former employee, officer or director of the Company or any of
     its Significant Subsidiaries or any

                                      A-13
<PAGE>   133

     beneficiary thereof entered into, maintained or contributed to, as the case
     may be, by the Company or any of its Subsidiaries (collectively, "Benefit
     Plans").

          (i) PARTICIPATION AND COVERAGE IN BENEFIT PLAN.  Except with respect
     to changes required by law, there has been no material adoption of,
     amendment to, written interpretation or announcement (whether or not
     written) by the Company or any of its Significant Subsidiaries relating to,
     or change in employee participation or coverage under, any Benefit Plan
     which would increase materially the expense of maintaining such Benefit
     Plan above the level of the expense incurred in respect thereof for the
     fiscal year ended on December 31, 1999.

          (j) ERISA COMPLIANCE.  (i) Section 4.1(j) of the Company Disclosure
     Schedule contains a list of all "Employee Pension Benefit Plans" (defined
     in Section 3(2) of the Employee Retirement Income Security Act of 1974, as
     amended ("ERISA")), "Employee Welfare Benefit Plans" (defined in Section
     3(l) of ERISA) and all other material Benefit Plans maintained, or
     contributed to, by the Company or any of its Subsidiaries or ERISA
     affiliates (defined below) for the benefit of any current or former
     employees, officers or directors of the Company or any of its Significant
     Subsidiaries or ERISA affiliates or under which the Company or any of its
     Significant Subsidiaries or ERISA affiliates has any material liability.
     The Company has delivered or made available to Parent complete and correct
     copies of (A) each material Benefit Plan (or, in the case of any unwritten
     Benefit Plans, descriptions thereof) and all amendments thereto and written
     interpretations thereof, (B) the most recent summary plan description for
     each material Benefit Plan for which such summary plan description is
     required and (C) each trust agreement and group annuity or insurance
     contract relating to any Benefit Plan. For purposes of this Agreement,
     "Erisa Affiliate" of the Company means any person which, together with the
     Company or any of its Subsidiaries, would be treated as a single employer
     under Section 414 of the Code. The only Benefit Plans which individually or
     collectively would constitute an "Employee Pension Benefit Plan" defined in
     Section 3(2) of ERISA (the "Pension Plans") are identified as such in
     Section 4.1(j) of the Company Disclosure Schedule.

             (ii) Each Benefit Plan has been maintained and administered in
        compliance with its terms in all material respects and with the
        requirements prescribed by any and all applicable statutes, orders,
        rules and regulations, and is, to the extent required by applicable law
        or contract, fully funded without having any deficit or unfunded
        actuarial liability. Any Benefit Plan intended to be qualified under
        Section 401(a) of the Code has been determined by the Internal Revenue
        Service to be so qualified and nothing has occurred that could
        reasonably be expected to cause the loss of such qualified status.

             (iii) No Benefit Plan is covered by Title IV of ERISA and no
        contributions to any Benefit Plan are required under Section 412 of the
        Code. Neither the Company nor any of its Subsidiaries has incurred or
        reasonably expects to incur any liability under Title IV of ERISA or
        Section 4975 of the Code or any material liability or penalty under
        Section 4980B of the Code or Section 502(i) of ERISA.

             (iv) To the knowledge of the Company, there are no pending or
        anticipated material claims against or otherwise involving any of the
        Benefit Plans and no suit, action or other litigation (excluding claims
        for benefits incurred in the

                                      A-14
<PAGE>   134

        ordinary course of Benefit Plan activities) has been brought against or
        with respect to any Benefit Plan.

             (v) All material contributions, reserves or premium payments,
        required to be made as of the date hereof to or with respect to the
        Benefit Plans have been made or provided for.

             (vi) Except as required by law, neither the Company nor any of its
        Subsidiaries have any material obligations for post-retirement or
        post-termination health and life benefits under any Benefit Plan.

          (k) TAXES.  As used in this Agreement, "Tax" or "Taxes" shall include
     all Federal, state, local and foreign income, property, sales, excise and
     other taxes, tariffs or governmental charges or assessments of any nature
     whatsoever as well as any interest, penalties and additions thereto. Except
     as set forth in Section 4.1(k) of the Company Disclosure Schedule:

             (i) The Company and each of its Subsidiaries have timely filed all
        tax returns, statements, reports and forms required to be filed with any
        tax authority (collectively, the "Tax Returns") and in accordance with
        all applicable laws, except as could not reasonably be expected to have
        a Company Material Adverse Effect. All the Tax Returns were correct and
        complete in all material respects when they were filed. All material
        Taxes shown as due and payable on the Tax Returns have been paid and all
        other material taxes of the Company or any of its Significant
        Subsidiaries have been adequately reserved for in the financial
        statements included in the Company SEC Documents in accordance with
        GAAP. There are no Liens on any of the assets of the Company or any of
        its Significant Subsidiaries that arose in connection with any failure
        (or alleged failure) to pay any Tax, other than Taxes that are not yet
        due, or that are being contested in good faith by appropriate
        proceedings.

             (ii) The Company and each of its Significant Subsidiaries has
        withheld and timely paid all material Taxes required to have been
        withheld and paid in connection with amounts paid or owing to any
        employee, independent contractor, creditor, stockholder, or other third
        party.

             (iii) No dispute or claim concerning any material tax liability of
        the Company or any of its Significant Subsidiaries has been proposed or
        claimed in writing or, to the knowledge of the Company, threatened by
        any authority. The Company has provided Parent with correct and complete
        copies of its Federal income tax returns for taxable years ending
        December 31, 1997 through December 31, 1998, and examination reports,
        and statements of deficiencies with respect to Federal income taxes, if
        any, assessed against or agreed to by the Company and any of its
        Significant Subsidiaries with respect to Federal income taxes for
        taxable years ending December 31, 1997 through December 31, 1998.

             (iv) Neither the Company nor any of its Significant Subsidiaries
        has waived any statute of limitations in respect of taxes or agreed to
        any extension of time with respect to a tax assessment or deficiency.

        its Significant Subsidiaries has any liability for the taxes of any

        consolidated federal income tax return) under Treas. Reg. ss.1.1502-6
        (or any similar provision of state, local, or foreign law), as a

        accounting method nor does the Company or any of its Significant
        Subsidiaries have any knowledge that the Internal Revenue Service (or
        other taxing authority) has proposed or is considering proposing, any
        such change in accounting method.

             (vii) Neither the Company nor any of its Significant Subsidiaries
        is a party to any agreement, contract, or arrangement that, individually

        deductible pursuant to the terms of Section 162(m), 280G or, to the
        knowledge of the Company, 162(a)(i) of the Code.

        355 of the Code (A) in the two years prior to the date of this
        Agreement, or (B) in a distribution that could otherwise constitute part
        of a "Plan" or "Series of Related Transactions" (within the meaning of
        Section 355(e) of the Code) in conjunction with the Merger.

          (l) VOTING REQUIREMENTS.  The Company Shareholder Vote is the only

     banker, financial advisor or other person, other than Chase H & Q, the fees
     and expenses of which will be paid by the Company (and a copy of whose

     finder's, financial advisor's or other similar fee or commission in

     to use the services or pay fees or expenses in connection with any future
     transaction.

          (o) PERMITS; COMPLIANCE WITH LAWS; ENVIRONMENTAL MATTERS.  (i) Each of
     the Company and its Significant Subsidiaries has in effect all material
     Federal, state, local

                                      A-16

     and foreign governmental approvals, authorizations, certificates, filings,
     franchises, licenses, notices, permits and rights ("Permits") necessary for
     it to own, lease or operate its properties and assets and to carry on its
     business as now conducted, and there has occurred no default under any such
     Permit, except for the absence of Permits and for defaults under Permits
     which absence or defaults, individually or in the aggregate, could not
     reasonably be expected to have a Company Material Adverse Effect. The
     Company and its Significant Subsidiaries have been, and are, in compliance
     with all applicable statutes, laws, ordinances, regulations, rules,
     judgments, decrees or orders of any Governmental Entity, and neither the
     Company nor any of its Subsidiaries has received any notice from any
     Governmental Entity or any other person that either the Company or any of
     its Subsidiaries is in violation of, or has violated, any applicable
     statutes, laws, ordinances, regulations, rules, judgments, decrees or
     orders, except such failures to comply or violations as, individually or in
     the aggregate, could not reasonably be expected to have a Company Material
     Adverse Effect.

             (ii) Except as could not reasonably be expected to have a Company
        Material Adverse Effect, neither the Company nor any of its Subsidiaries
        has (i) held, released, transported or disposed of any Hazardous
        Substance (as hereinafter defined) on, under, from or at any of the
        Company's or any of its Subsidiaries' properties, other than in a manner
        that could not, in all such cases taken individually or in the
        aggregate, reasonably be expected to have or result in a Company
        Material Adverse Effect, (ii) any knowledge of the presence of any
        Hazardous Substances that have been released into the environment on,
        under or at any of the Company's or any of its Subsidiaries' properties
        other than that which could not reasonably be expected to have or result
        in a Company Material Adverse Effect, or (iii) received any written
        notice (A) of any violation of any applicable statute, law, ordinance,
        regulation, rule, judgment, decree or order of any Governmental Entity
        relating to any matter of pollution, protection of the environment or
        environmental regulation or control or regarding Hazardous Substances
        (collectively, "Environmental Laws") that has not been resolved or
        settled with the relevant Governmental Entity, (B) of the institution or
        pendency of any suit, action, claim, proceeding or investigation by any
        Governmental Entity or any third party in connection with any violation
        of Environmental Laws, (C) requiring the response to or remediation of
        Hazardous Substances at or arising from any of the Company's or any of
        its Subsidiaries' properties or any other properties, (D) alleging
        non-compliance by the Company or any of its Subsidiaries with the terms
        of any permit required under any Environmental Law in any manner
        reasonably likely to require material expenditures or to result in
        material liability or (E) demanding payment of a material amount for
        response to or remediation of Hazardous Substances at or arising from
        any of the Company's or any of its Subsidiaries' properties or any other
        properties. For purposes of this Agreement, the term "Hazardous
        Substance" shall mean any material defined as toxic or hazardous,
        including any petroleum and petroleum products, under any applicable
        Environmental Law.

          (p) CONTRACTS; DEBT INSTRUMENTS.  (i) Except as otherwise disclosed in
     Section 4.1(p) of the Company Disclosure or in the Company SEC Documents,
     neither the Company nor any of its Significant Subsidiaries is a party to
     or subject to (i) any "material contracts" (as such term is defined in Item
     601(b)(10) of Regulation S-K of the SEC) or (ii) any agreement contract,
     policy, license, permit,

                                      A-17
<PAGE>   137

     document, instrument, arrangement or commitment that provides for a non-
     competition covenant with any person or entity or in any geographic area
     and which limits in any material respect the ability of the Company or any
     Significant Subsidiary to compete in its current business lines. All
     material contracts (as such term is defined in Item 601(b)(10) of
     Regulation S-K of the SEC) to which the Company or any Significant
     Subsidiary is a party are valid and in full force and effect, except to the
     extent they have previously expired in accordance with their terms or if
     the failure to be in full force and effect, individually or in the
     aggregate, would not reasonably be expected to have a Company Material
     Adverse Effect. Neither the Company nor any of its Significant Subsidiaries
     has violated any provision of, or committed or failed to perform any act
     which with or without notice, lapse of time or both would constitute a
     default under the provisions of, any material contract (as such term is
     defined in Item 601(b)(10) of Regulation S-K of the SEC), except in each
     case for those violations and defaults which, individually or in the
     aggregate, would not reasonably be expected to result in a Company Material
     Adverse Effect. As of the date hereof, there has not been an event that
     would constitute a default (with or without notice or lapse of time, or
     both) by the Company under the Cybear Agreements (as hereinafter defined).

          (q) TITLE TO PROPERTIES.  (i) Except as otherwise disclosed in Section
     4.1(q) of the Company Disclosure Schedule, each of the Company and its
     Significant Subsidiaries has good and marketable title to, or valid
     leasehold interests in, all its properties and assets, free and clear of
     all Liens, except for defects in title, easements, restrictive covenants
     and similar encumbrances or impediments that, in the aggregate, could not
     reasonably be expected to have a Company Material Adverse Effect.

             (ii) Each of the Company and its Significant Subsidiaries has
        complied in all material respects with the terms of all leases to which
        it is a party and under which it is in occupancy, and all such leases
        are in full force and effect. Each of the Company and its Significant
        Subsidiaries enjoys peaceful and undisturbed possession under all such
        leases in all material respects.

          (r) OPINION OF FINANCIAL ADVISOR.  The Company has received the
     opinion of Chase H & Q dated the date hereof, a copy of which has been or
     promptly will be made available to Parent, to the effect that, as of such
     date, the consideration to be received by the holders of Company Common
     Stock in the Merger pursuant to this Agreement is fair to such holders from
     a financial point of view.

          (s) INTERESTS OF OFFICERS AND DIRECTORS.  Except as set forth in
     Section 4.1(s) of the Company Disclosure Schedule, none of the Company's
     officers or directors has any material direct or indirect interest in any
     material property, real or personal, tangible or intangible, including
     inventions, patents, copyrights, trademarks, trade names, trade secrets or
     know-how, used in or pertaining to the business of the Company or that of
     its Subsidiaries, or any supplier, distributor or customer of the Company
     or any of its Significant Subsidiaries, except for the normal rights of a
     stockholder and rights under existing employee benefit plans. Except as set
     forth in Section 4.1(s) of the Company Disclosure Schedule, no loans or
     advances have been made by the Company to officers and directors of the
     Company.

          (t) SOFTWARE.  (i) "Owned Software" shall mean all computer programs
     (source code or object code) owned by the Company or any Significant
     Subsidiary of the Company, including without limitation any computer
     programs in the development or

                                      A-18
<PAGE>   138

     testing phase. "Licensed Software" shall mean all computer programs (source
     code or object code) licensed to the Company or any Significant Subsidiary
     of the Company by any third party (other than any off-the-shelf computer
     program that is so licensed under a shrink wrap license) (the Licensed
     Software and the Owned Software, the "Software").

             (ii) Except as specified in Section 4.1(t) of the Company
        Disclosure Schedule, Company, directly or through its Subsidiaries, has
        good, marketable and exclusive title to, and the valid power and right
        to sell, license, lease, transfer, use or otherwise exploit, all of the
        Owned Software and all copyrights thereof, free and clear of all Liens
        and except in the aggregate as could not reasonably be expected to have
        a Company Material Adverse Effect. The Company, directly or through its
        Subsidiaries, is in actual possession of or has all necessary control
        over (A) the source code and object code for each computer program
        included in the Owned Software and (B) the object code and, to the
        extent required for the use of the Software as currently used in the
        Company's business or as offered to the Company's customers or potential
        customers the source code for each computer program included in the
        Licensed Software. The Company, directly or through its Subsidiaries, is
        in possession of or has necessary control over all documentation
        (including without limitation all related engineering specifications,
        program flow charts, installation and user manuals) and know-how
        required for the use of the Software as currently used in the Company's
        business or as offered to the Company's customers or potential
        customers. Except as specified in Section 4.1(t) of the Company
        Disclosure Schedule, no person other than the Company and its
        Subsidiaries has any material right or interest of any kind or nature in
        or with respect to the Owned Software or any portion thereof or any
        rights to sell, license, lease, transfer, use or otherwise exploit the
        Owned Software or any portion thereof.

             (iii) Since the Company and its Significant Subsidiaries have owned
        the Owned Software, to the knowledge of the management of the Company
        after due inquiry, the Company and its Significant Subsidiaries have
        disclosed source code to the Owned Software only pursuant to
        confidentiality terms that reasonably protect the Company's rights in
        such Owned Software. Except as disclosed in accordance with such
        confidentiality agreements or valid source code escrow agreements, to
        the knowledge of the management of the Company after due inquiry, no
        person (other than the Company and its Significant Subsidiaries) is in
        possession of any source code for any computer program included in the
        Owned Software.

             (iv) There are no defects in (a) any Licensed Software included in
        the Owned Software, or (b) in the Owned Software, in each case of the
        currently Company supported versions thereof, that would substantially
        adversely affect the functioning thereof in accordance with any
        published specifications therefor in such a manner as could reasonably
        be expected to have a Company Material Adverse Effect.

             (v) To the knowledge of the management of the Company after due
        inquiry, except as set forth in Section 4.1(t) of the Company Disclosure
        Schedule, none of the sale, license, lease, transfer, use, reproduction,
        distribution, modification or other exploitation by the Company, any
        Significant Subsidiary or any of their respective successors or assigns
        of any version or release of any

                                      A-19
<PAGE>   139

        computer program included in the Software obligates or will obligate the
        Company, any Significant Subsidiary or any of their respective
        successors or assigns to pay any material royalty, fee or other
        compensation to any other Person.

             (vi) Except as specified in Section 4.1(t) of the Company
        Disclosure Schedule, no material agreement, license or other arrangement
        pertaining to any of the Software (including without limitation any
        development, distribution, marketing, user or maintenance agreement,
        license or arrangement) to which the Company or any Significant
        Subsidiary is a party will terminate or become terminable by any party
        thereto as a result of the execution, delivery or performance of this
        Agreement or the consummation of the transactions contemplated hereby.
        Section 4.1(t) of the Company Disclosure Schedule sets forth the general
        licensing policies of the Company and Significant Subsidiaries by
        category of Software.

          (u) INTELLECTUAL PROPERTY.  (i) For purposes of this Section 4.1(u),
     "Intellectual Property" shall mean all patents, trademarks, trade names,
     service marks, and domain names and registered copyrights and material
     non-registered copyrights used by the Company or any Significant Subsidiary
     of the Company in connection with the conduct of the Company's business,
     and all registrations of or applications for registration of any of the
     foregoing, including any additions thereto or extensions, continuations,
     renewals or divisions thereof, together with all trade dress, trade
     secrets, processes, formulae, designs, know-how and other intellectual
     property rights that are so used. The Company has heretofore furnished or
     made available to Parent a true and correct summary of each U.S. and
     foreign registration or application for U.S. and foreign registration of
     patents, trademarks and tradenames which is registered with, or in respect
     of which any application for registration has been filed with, any
     Governmental Entity. To the knowledge of the management of the Company
     after due inquiry, all such registrations and applications are valid and
     subsisting, in full force and effect, and have not been cancelled, expired
     or abandoned (except as otherwise noted in such reports). To the knowledge
     of the management of the Company after due inquiry, the Company is listed
     in the records of the appropriate Governmental Entity or foreign government
     equivalent entity as the sole owner of record for each such application and
     registration.

             (ii) The Intellectual Property includes all of the material
        intellectual property rights owned or licensed by the Company and its
        Significant Subsidiaries that are reasonably necessary to conduct the
        Company's business as it is now conducted, and includes all of the
        intellectual property rights owned by or licensed to the Company and its
        Significant Subsidiaries that are used in the development, marketing,
        licensing or support of the Software. Except as specified in Section
        4.1(u) of the Company Disclosure Schedule, (A) the Company, directly or
        through its Subsidiaries, has good, marketable and exclusive title to,
        and the valid power and right to use, the material Intellectual Property
        owned by the Company or its Subsidiaries free and clear of all Liens and
        (B) no person or entity other than the Company and its Subsidiaries has
        any right or interest of any kind or nature in or with respect to the
        material Intellectual Property or any portion thereof or any rights to
        use, market or exploit the material Intellectual Property or any portion
        thereof other than pursuant to agreements entered into in the ordinary
        course of business. Section 4.1(u) of the Company Disclosure

<PAGE>   140

        Schedule sets forth all material registered trademarks, material pending
        trademarks, material patents and material copyrights of the Company and
        its Subsidiaries including the name of the entity that holds such items.

             (iii) The Company and its Significant Subsidiaries take reasonable
        measures to protect the confidentiality of its material trade secrets,
        know-how or other confidential information, including by generally
        requiring employees, independent contractors and licensees having access
        thereto to execute written non-disclosure agreements that adequately
        protect the Company's and its Significant Subsidiaries' proprietary
        interests in and to such trade secrets, know-how and other confidential
        information.

          (v) NO INFRINGEMENT.  (i) Except as specified in Section 4.1(v) of the
     Company Disclosure Schedule neither the existence nor the sale, license,
     lease, transfer, use, reproduction, distribution, modification or other
     exploitation by the Company or any Significant Subsidiary of the Company of
     any Software or Intellectual Property, as such Software or Intellectual
     Property, as the case may be, is or was, or is currently contemplated to
     be, sold, licensed, leased, transferred, used or otherwise exploited by
     such persons, does, did or will (i) infringe on any patent, trademark,
     copyright or other right of any person, (ii) constitute a misuse or
     misappropriation of any trade secret, know-how, process, proprietary
     information or other right of any other person, or (iii) entitle any other
     person to any interest therein, or right to compensation from the Company,
     any Significant Subsidiary of the Company or any of their respective
     successors or assigns, by reason thereof (it being understood and agreed
     that, insofar as the foregoing representation and warranty relates to
     Software and Intellectual Property that is licensed to the Company or any
     Significant Subsidiary of the Company by any third party, or as it relates
     to patents and trademarks, such representation and warranty is made only to
     the Company's knowledge). Except as specified in Section 4.1(v) of the
     Company Disclosure Schedule neither the Company nor any of its Subsidiaries

     expected to give rise to any lawsuit, claim, demand, proceeding or
     investigation. Except as specified in Section 4.1(v) of the Company
     Disclosure Schedule, there are no material restrictions on the ability of
     the Company, any Significant Subsidiary of the Company or any of their
     respective successors or assigns to sell, license, lease, transfer, use,
     reproduce, distribute, modify or otherwise exploit any Software or
     Intellectual Property.

             (ii) Except as specified in Schedule 4.1(v) of the Company
        Disclosure Schedule, the Company and its Significant Subsidiaries are
        not aware of any material infringement, misappropriation or other
        violation of any Software or Intellectual Property, and no lawsuit,
        claim, demand, proceeding or investigation brought by the Company or any
        of its Significant Subsidiaries with respect to Owned Software is
        pending against any third party.

          (w) CHANGE OF CONTROL.  Except as described in Section 4.1(w) of the
     Company Disclosure Schedule, the execution and delivery of this Agreement
     and the consummation of the transactions contemplated hereby will not (i)
     result in any payment (including severance, unemployment compensation, tax
     gross-up, bonus or otherwise) becoming due to any current or former
     director, employee or independent contractor of the Company or any
     Significant Subsidiary, from the Company or any

                                      A-21

     Significant Subsidiary under any Stock Plan, Benefit Plan, agreement or

     any Stock Plan, Benefit Plan, agreement or otherwise or (iii) result in the
     acceleration of the time of payment, exercise or vesting of any such

     Section 4.2 REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUBSIDIARY.
Except as set forth in the Parent SEC Documents (as hereinafter defined) or in
the disclosure schedule delivered by Parent and Merger Subsidiary to the Company
prior to the execution of this Agreement (the "Parent Disclosure Schedule"),
Parent and Merger Subsidiary jointly and severally represent and warrant to the
Company as follows:

          (a) ORGANIZATION, STANDING AND CORPORATE POWER.  Each of Parent and
     Merger Subsidiary is a corporation duly organized, validly existing and in
     good standing under the laws of the state of its organization and has all
     requisite corporate power and authority, as the case may be, to own and
     operate its properties and assets and to carry on its business as now being
     conducted. Each of Parent and Merger Subsidiary is duly qualified or
     licensed to do business and is in good standing in each jurisdiction in
     which the nature of its business or the ownership or leasing of its
     properties makes such qualification or licensing necessary, except where
     the failure to be so qualified, licensed or in good standing (individually
     or in the aggregate) could not reasonably be expected to have a Parent
     Material Adverse Effect. For purposes of this Agreement, "Parent Material
     Adverse Effect" means any change, effect, event, occurrence, state of facts
     or development that is materially adverse to the business, financial
     condition or results of operations of Parent and its Subsidiaries, and
     taking Parent and its Subsidiaries together as a whole; provided, however,
     that none of the following shall be deemed in themselves, either alone or
     in combination, to constitute a Parent Material Adverse Effect: (a) any
     change in the market price or trading volume of Parent's stock after the

     facts or development relating to (i) the announcement or pendency of the
     transactions contemplated by this Agreement, (ii) conditions affecting the
     industries in which the Parent participates or the U.S. economy as a whole,

     in the Parent Disclosure Schedule, in each case, as amended to the date of
     this Agreement. Parent has provided the Company with complete and correct
     copies of its and Merger Subsidiary's certificates of incorporation and
     by-laws, in each case, as amended to the date of this Agreement.

          (b) CAPITAL STRUCTURE.  Section 4.2(b) of the Parent Disclosure
     Schedule sets forth the authorized, issued and outstanding capital stock of
     Parent. Except as set forth in Section 4.2(b) of the Parent Disclosure
     Schedule, at the close of business on June 29, 2000, no shares of capital
     stock or other voting securities of Parent were issued, reserved for
     issuance or outstanding. All outstanding shares of capital stock of Parent
     are duly authorized, validly issued, fully paid and nonassessable and not
     subject to preemptive rights except as could not reasonably be expected to
     have a Parent Material Adverse Effect. Except as set forth on Section
     4.2(b) of the Parent

                                      A-22
<PAGE>   142

     Disclosure Schedule, there are outstanding no bonds, debentures, notes or
     other indebtedness of Parent having the right to vote (or convertible into,
     or exchangeable for, securities having the right to vote) on any matters on
     which holders of Parent Common Stock may vote. As of the date of this
     Agreement, the authorized capital stock of Merger Subsidiary consists of
     10,000 shares of common stock, par value $.0001 per share, all of which
     have been validly issued, are fully paid and nonassessable and are owned by
     Parent free and clear of any Liens. Except as set forth in Section 4.2(b)
     of the Parent Disclosure Schedule, there are no outstanding options,
     warrants, calls, rights, commitments, agreements or undertakings of any
     kind to which Parent or Merger Subsidiary or any of their Subsidiaries is a
     party or by which any of them is bound obligating Parent or Merger
     Subsidiary or any of their Subsidiaries to issue, deliver or sell, or cause
     to be issued, delivered or sold, additional shares of capital stock or
     other voting securities of Parent or Merger Subsidiary or of any of their
     Subsidiaries or obligating Parent or Merger Subsidiary or any of their
     Subsidiaries to issue, grant, extend or enter into any such option,
     warrant, call, right, commitment, agreement, or undertaking. There are no
     outstanding rights, commitments, agreements, or undertakings of any kind
     obligating Parent or Merger Subsidiary or any of their Subsidiaries to
     repurchase, redeem or otherwise acquire any shares of capital stock or
     other voting securities of Parent or Merger Subsidiary or any of their
     Subsidiaries or any securities of the type described in the two immediately
     preceding sentences.

          (c) AUTHORITY; NONCONTRAVENTION.  Parent and Merger Subsidiary have
     the requisite corporate power and authority to enter into this Agreement
     and, subject only to the approval of the issuance of Parent Common Stock in
     the Merger by the affirmative vote of holders of a majority of the
     outstanding shares of Parent Common Stock (the "Parent Shareholder Vote"),
     to execute, deliver and perform their obligations under this Agreement and
     to consummate the transactions contemplated by this Agreement. Prior to the
     Effective Time, Parent will have taken all necessary action to permit it to
     issue the number of shares of Parent Common Stock required to be issued
     pursuant to Article II. The Parent Common Stock, when issued, will be
     validly issued, fully paid and nonassessable, and no holder of Parent
     Common Stock will have any preemptive right of subscription or purchase in
     respect thereof. The Parent Common Stock, when issued, will be registered
     under the Securities Act and Exchange Act and registered or exempt from
     registration under any applicable state securities or "blue sky" laws. This
     Agreement has been duly executed and delivered by Parent and Merger
     Subsidiary and constitutes a valid and binding obligation of Parent and
     Merger Subsidiary, enforceable against each of them in accordance with its
     terms, subject to bankruptcy, insolvency, fraudulent transfer,
     reorganization, moratorium and similar laws of general applicability
     relating to or affecting creditors' rights and to general equity
     principles. The execution and delivery of this Agreement do not, and the
     consummation of the transactions contemplated by this Agreement and
     compliance with the provisions of this Agreement will not, constitute or
     result in (i) a breach or violation of, or default (with or without notice
     or lapse of time, or both) under, the certificate of incorporation or
     by-laws of Parent or Merger Subsidiary, (ii) a breach or violation of, or
     default (with or without notice or lapse of time, or both) under, any loan
     or credit agreement, note, bond, mortgage, indenture, lease or other
     agreement, instrument or license applicable to Parent or any of its
     Subsidiaries or their respective properties or assets or (iii) subject to
     the governmental filings and other matters referred to in the following
     sentence, a breach or violation of, or default (with or without notice or
     lapse of time, or both) under, any judgment,

                                      A-23

     order, decree, statute, law, ordinance, rule or regulation applicable to
     Parent, Merger Subsidiary or any other subsidiary of Parent or their
     respective properties or assets, other than, in the case of clause (ii) or
     (iii), any such breaches, violations or defaults that individually or in
     the aggregate could not reasonably be expected to (x) have a Parent
     Material Adverse Effect, (y) materially impair the ability of Parent and
     Merger Subsidiary to perform their respective obligations under this
     Agreement or (z) prevent or materially delay the consummation of any of the
     transactions contemplated by this Agreement. No Consent is required by or
     with respect to Parent or Merger Subsidiary in connection with the
     execution and delivery by Parent and Merger Subsidiary of this Agreement or
     the consummation by Parent or Merger Subsidiary of the transactions
     contemplated by this Agreement, except for (i) the filing with the SEC of
     (A) the Form S-4, (B) the Joint Proxy Statement, and (C) such reports under
     the Exchange Act and the Securities Act as may be required in connection
     with this Agreement and the transactions contemplated hereby and thereby,
     (ii) such filings as may be required under state securities or "blue sky"
     laws, (iii) the filing of the Certificate of Merger with the Delaware
     Secretary of State and appropriate documents with the relevant authorities
     of other states in which Parent and Merger Subsidiary are qualified to do
     business, (iv) such filings with and approvals of the NASDAQ-SM to permit
     the shares of Parent Common Stock that are to be issued upon consummation
     of the Merger to be listed on the NASDAQ-SM, and (vi) such other consents,
     approvals, orders, authorizations, registrations, declarations and filings,
     the failure of which to be made or obtained individually or in the
     aggregate could not reasonably be expected to (x) have a Parent Material
     Adverse Effect, (y) materially impair the Parent's or Merger Subsidiary's
     ability to perform its obligations under this Agreement or (z) prevent or
     materially delay the consummation of the transactions contemplated by this
     Agreement.

          (d) SEC DOCUMENTS; FINANCIAL STATEMENTS; NO UNDISCLOSED
     LIABILITIES.  Parent has filed all required reports, schedules, forms,
     statements and other documents with the SEC since January 1, 1999 (the
     "Parent SEC Documents"). As of their respective dates, the Parent SEC
     Documents complied in all material respects with the requirements of the
     Securities Act or the Exchange Act, as the case may be, and the rules and
     regulations of the SEC promulgated thereunder applicable to such Parent SEC
     Documents, and none of the Parent SEC Documents when filed contained any
     untrue statement of a material fact or omitted 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 consolidated financial statements of Parent included in the
     Parent SEC Documents as of their respective dates comply as to form in all
     material respects with applicable accounting requirements and the published
     rules and regulations of the SEC with respect thereto, have been prepared
     in accordance with generally accepted accounting principles (except, in the
     case of unaudited statements, as permitted by Form 10-Q of the SEC) applied
     on a consistent basis during the periods involved (except as may be
     indicated in the notes thereto) and fairly present in all material respects
     the consolidated financial position of Parent and its consolidated
     Subsidiaries as of the dates thereof and the consolidated results of their
     operations and cash flows for the periods then ended (subject, in the case
     of unaudited statements, to normal and recurring year-end audit
     adjustments). Except as reflected in the financial statements of Parent
     included in the Parent SEC Documents, neither Parent nor any of its
     Subsidiaries has any liabilities or obligations of any nature (whether
     accrued, absolute, contingent or otherwise) which are required by GAAP to
     be set forth on a

                                      A-24
<PAGE>   144

     consolidated balance sheet of Parent and its consolidated Subsidiaries or
     in the notes thereto other than any liabilities and obligations incurred
     since March 31, 2000 in the ordinary course of business or which,
     individually or in the aggregate, could not reasonably be expected to have
     a Parent Material Adverse Effect.

          (e) ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as disclosed in
     Section 4.2(e) of the Parent Disclosure Schedule and except as expressly
     contemplated by this Agreement, since March 31, 2000, Parent and its
     Subsidiaries have conducted their business only in the ordinary course
     consistent with past practice, and there has not been (i) any change in the
     financial condition, properties, business or results of operations of the
     Parent or its Subsidiaries or any development or combination of
     developments of which management of the Parent has, or should reasonably
     have, knowledge that, individually or in the aggregate, has had or is
     reasonably likely to have a Parent Material Adverse Effect, (ii) any
     material damage, destruction or other casualty loss, whether or not covered
     by insurance, with respect to any material asset or property owned, leased
     or otherwise used by Parent or any of its Subsidiaries that has had or
     could reasonably be expected to have a Parent Material Adverse Effect,
     (iii) any change in accounting methods, principles or practices by Parent
     or any of its Subsidiaries or (iv) any material agreement, commitment,
     arrangement or undertaking by Parent or any of its Subsidiaries to perform
     any action described in clauses (i) through (iii) above.

          (f) LITIGATION.  Except as disclosed in the Parent SEC Documents or in
     Section 4.2(f) of the Parent Disclosure Schedule there is no suit, action
     or proceeding pending or, to the knowledge of the management of Parent,
     threatened against or affecting Parent or any of its Subsidiaries (and
     Parent is not aware of any basis for any such suit, action or proceeding)
     that, individually or in the aggregate, could reasonably be expected to (i)
     have a Parent Material Adverse Effect, (ii) impair the ability of Parent or
     any of its Subsidiaries to perform their obligations under this Agreement
     or (iii) prevent or materially delay the consummation of any of the
     transactions contemplated by this Agreement, nor is there any judgment,
     decree, injunction, rule or order of any Governmental Entity or arbitrator
     outstanding against Parent or any of its Subsidiaries having, or which
     could reasonably be expected to have, any such effect.

          (g) TAXES.  (i) Parent and each of its Subsidiaries have timely filed
     all Tax Returns in accordance with all applicable laws, except as could not
     reasonably be expected to have a Parent Material Adverse Effect. All the
     Tax Returns were correct and complete in all material respects when they
     were filed. All material Taxes shown as due and payable on the Tax Returns
     have been paid and all other material taxes of Parent or any of its
     Subsidiaries have been adequately reserved for in the financial statements
     included in the Parent SEC Documents in accordance with GAAP. There are no
     Liens on any of the assets of Parent or any of its Subsidiaries that arose
     in connection with any failure (or alleged failure) to pay any Tax, other
     than Taxes that are not yet due, or that are being contested in good faith
     by appropriate proceedings.

             (ii) Parent and each of its Subsidiaries have withheld and timely
        paid all material Taxes required to have been withheld and paid in
        connection with amounts paid or owing to any employee, independent
        contractor, creditor, stockholder, or other third party.

<PAGE>   145

             (iii) No dispute or claim concerning any tax liability of Parent or
        any of its Subsidiaries has been proposed or claimed in writing or, to
        the knowledge of Parent, threatened by any authority. Parent has
        provided the Company with correct and complete copies of its Federal
        income tax returns for the taxable year ending June 30, 1999, and
        examination reports, and statements of deficiencies with respect to
        Federal income taxes, if any, assessed against or agreed to by Parent
        and any of its Subsidiaries with respect to Federal income taxes for the
        taxable year ending June 30, 1999.

             (iv) Neither Parent nor any of its Subsidiaries has waived any
        statute of limitations in respect of taxes or agreed to any extension of
        time with respect to a tax assessment or deficiency.

             (v) Neither Parent nor any of its Subsidiaries has filed a consent
        pursuant to Section 341(f) of the Code concerning collapsible
        corporations. Neither Parent nor any of its Subsidiaries is a party to
        any tax allocation or sharing agreement. Neither Parent nor any of its
        Subsidiaries has any liability for the taxes of any person (other than
        Parent and any of its Subsidiaries that is currently a member of
        Parent's affiliated group filing a consolidated federal income tax
        return) under Treas. Reg. ss.1.1502-6 (or any similar provision of
        state, local, or foreign law), as a transferee or successor, by
        contract, or otherwise.

             (vi) Neither Parent nor any of its Subsidiaries is required to
        include in income any adjustment pursuant to Section 481(a) of the Code
        (or similar provisions of other law or regulations) in its current or in
        any future taxable period by reason of a change in accounting method nor
        does Parent or any of its Subsidiaries have any knowledge that the
        Internal Revenue Service (or other taxing authority) has proposed or is
        considering proposing, any such change in accounting method.

             (vii) Neither Parent nor any of its Subsidiaries is a party to any
        agreement, contract, or arrangement that, individually or collectively,
        could give rise to the payment of any amount (whether in cash or
        property, including Parent Common Stock) that would not be deductible
        pursuant to the terms of Section 162(m), 280G or, to the knowledge of
        Parent, 162(a)(i) of the Code.

             (viii) Neither Parent nor any of its Subsidiaries has constituted
        either a "Distributing Corporation" or a "Controlled Corporation"
        (within the meaning of Section 355(a)(1)(A) of the Code) in a
        distribution of stock qualifying for tax-free treatment under Section
        355 of the Code (A) in the two years prior to the date of this
        Agreement, or (B) in a distribution that could otherwise constitute part
        of a "Plan" or "Series Of Related Transactions" (within the meaning of
        Section 355(e) of the Code) in conjunction with the Merger.

          (h) COMPLIANCE WITH APPLICABLE LAWS.  As of the date of this
     Agreement, each of Parent and its Subsidiaries has in effect all Permits
     necessary for it to own, lease or operate its properties and assets and to
     carry on its business as now conducted, and there has occurred no default
     under any such Permit, except for the absence of Permits and for defaults
     under Permits which absence or default, individually or in the aggregate,
     could not reasonably be expected to have a Parent Material Adverse Effect.
     As of the date of this Agreement, Parent and its Subsidiaries have been,
     and are, in compliance with all applicable statutes, laws, ordinances,
     rules, orders and regulations

                                      A-26
<PAGE>   146

     of any Governmental Entity, except for such failures to comply or
     violations as, individually or in the aggregate, could not reasonably be
     expected to have a Parent Material Adverse Effect.

          (i) BROKERS.  No broker, investment banker, financial advisor or other
     person, other than Gruntal & Co., LLC, the fees and expenses of which will
     be paid by Parent, is entitled to any broker's, finder's, financial
     advisor's or other similar fee or commission in connection with the
     transactions contemplated by this Agreement based upon arrangements made by
     or on behalf of Parent or Merger Subsidiary.

          (j) NO PRIOR ACTIVITIES; ASSETS OF MERGER SUBSIDIARY.  Merger
     Subsidiary was formed solely for the purpose of the Merger and engaging in
     the transactions contemplated hereby. As of the date hereof and the
     Effective Time, except for obligations or liabilities incurred in
     connection with its incorporation or organization and the transactions
     contemplated hereby and activities, agreements or arrangements in
     connection with the transactions contemplated hereby, Merger Subsidiary has
     not and will not have (i) incurred, directly or indirectly through any of
     its Subsidiaries or affiliates, any obligations or liabilities, (ii)
     engaged in any business or activities of any type or kind whatsoever or
     (iii) entered into any agreements or arrangements with any person.

          (k) OPINION OF FINANCIAL ADVISOR.  Parent has received the opinion of
     Gruntal & Co., LLC dated the date hereof, a copy of which has been or
     promptly will be made available to the Company, to the effect that, as of
     such date, the consideration to be exchanged by the Parent in the Merger
     pursuant to this Agreement is fair to Parent from a financial point of
     view.

     requiring payments in excess of $100,000, (vi) enter into or amend any
     agreement or arrangement for obtaining professional services or advice
     requiring payments of more than $50,000 to any one service provider
     (provided that this clause (vi) does not apply to legal services or advice
     obtained in connection with the transactions contemplated by this
     Agreement), (vii) enter into any product swap transactions that would be in
     violation of generally accepted accounting principles, (viii) make any

     Subsidiaries, or (ix) enter into or adopt, or amend any material agreement,
     arrangement, or Benefit Plan so as to increase the liability (whether or
     not contingent) of the Company or Parent or any of their Subsidiaries in
     respect of compensation or benefits except as may be required by applicable
     law; or

          (k) authorize any of, or commit or agree to take any of, the foregoing
     actions.

     Section 5.2 STATE TAKEOVER STATUTES.  If any takeover statute is or may
become applicable to the Merger or the other transactions contemplated by this
Agreement, the Company and its board of directors shall grant such approvals and
take such actions as are necessary so that such transactions may be consummated
as promptly as practicable on the

                                      A-29
<PAGE>   149

terms contemplated by this Agreement or by the Merger and otherwise act to
eliminate or minimize the effects of such statute or regulation on such
transactions.

     Section 5.3 ACCESS TO INFORMATION.  Subject to applicable law, the Company
shall, and shall cause each of its Subsidiaries to, afford to Parent, and to
Parent's officers, employees, accountants, counsel, financial advisers and other
representatives, reasonable access during normal business hours and upon notice
given by Parent to the Company during the period prior to the Effective Time to
all their respective properties, books, contracts, commitments, personnel
(including for the purpose of interviewing such personnel in connection with the
integration process) and records and their accountants' work papers and, during
such period, the Company shall, and shall cause each of its Subsidiaries to,
furnish promptly to Parent (i) a copy of each report, schedule, registration
statement and other document filed by it during such period pursuant to the
requirements of Federal or state securities laws, (ii) a copy of each material
tax return, report and information statement filed by it during such period, and
(iii) all other information concerning its business, assets, properties and
personnel as Parent may reasonably request; provided that no investigation
pursuant to this Section 5.3 shall affect any representation or warranty given
by the Company to Parent hereunder.

     Section 5.4 NO SOLICITATION BY THE COMPANY.  (a) From the date of this
Agreement until the Effective Time or, if earlier, the termination of this
Agreement in accordance with its terms, the Company shall not (whether directly
or indirectly through advisors, agents or other intermediaries), and the Company
shall not permit or cause its and its Subsidiaries' respective officers,
directors, advisors, representatives and other agents to, directly or
indirectly, (i) solicit, initiate or knowingly encourage, or take any other
action to facilitate, any inquiries or the making of any proposal that
constitutes, or may reasonably be expected to lead to, any Acquisition Proposal
(as hereinafter defined) or (ii) participate or engage in substantive
discussions or negotiations with, or disclose or provide any non-public
information relating to the Company or its Subsidiaries or afford access to the
properties, books or records of the Company or its Subsidiaries to, any person
(including any "Person" as defined in Section 13(d)(3) of the Exchange Act) that
has made an Acquisition Proposal or with or to any Person in contemplation of an
Acquisition Proposal or (iii) enter into any agreement or agreement in principle
providing for or relating to an Acquisition Proposal; provided, however, that if
and only if (A) a person has submitted an unsolicited written Acquisition
Proposal (under circumstances in which the Company has complied with its
obligations under this Section 5.4(a)) to the Company's Board of Directors, (B)
the Company's Board of Directors believes in good faith, based on such matters
as it deems relevant, including the advice of the Company's financial advisor,
that such Acquisition Proposal is a Superior Proposal and (C) the Company's
Board of Directors determines in good faith, based on such matters as it deems
relevant, including consultation with the Company's outside legal counsel, that
engaging in such negotiations or discussions or providing such information is
required to satisfy the fiduciary duties of the Board of Directors of the
Company under applicable law, then the Company may furnish information to such
person with respect to the Company and its Subsidiaries (so long as the Company
has entered into a customary confidentiality agreement with such party) and
participate in negotiations and discussions with such person regarding such
Acquisition Proposal (as hereinafter defined); provided further that, after the
third business day following Parent's receipt of written notice advising Parent
that the Company's Board of Directors is prepared to accept such Superior
Proposal, which notice specifies the material terms and conditions of such
Superior Proposal and identifies the person making such Superior Proposal, the
Board of Directors of the Company may, in response to a Superior

                                      A-30
<PAGE>   150

Proposal which was not solicited by the Company and which did not otherwise
result from a breach of this Section 5.4(a), approve or recommend, or propose to
approve or recommend, any such Acquisition Proposal or terminate this Agreement,
if the Board of Directors of the Company determines in good faith, based on such
matters as it deems relevant, including consultation with the Company's outside
legal counsel, that it is required to do so in order to comply with its
fiduciary duties to the holders of Company Common Stock under applicable law,
and, concurrently with such termination, causes the Company to pay the fee
payable pursuant to Section 9.5(a) hereof by reason thereof. Nothing contained
in this Agreement shall prohibit the Company or the Company's Board of Directors
from taking and disclosing to the holders of Company Common Stock a position
with respect to a tender or exchange offer by a third party pursuant to Rules
14d-9 and 14e-2(a) promulgated under the Exchange Act or from making any
disclosure required by applicable law or, in the case of the Company's Board of
Directors, making any other disclosure to the holders of Company Common Stock
that the Company's Board of Directors determines in good faith is required to be
made to satisfy the fiduciary duties of the Company's Board of Directors under
applicable law. The Company shall immediately cease and cause to be terminated
and shall cause its affiliates and Subsidiaries and its or their respective
officers, directors, employees, representatives or agents, to terminate all
existing discussions or negotiations, if any, with any persons conducted
heretofore with respect to, or that could reasonably be expected to lead to, an
Acquisition Proposal.

     (b) For purposes of this Agreement, "Acquisition Proposal" shall mean any
inquiry, proposal or offer from any person (other than Parent, Merger Subsidiary
or any of their affiliates) relating to any merger, consolidation,
recapitalization, liquidation or other direct or indirect business combination,
involving the Company or the issuance or acquisition of shares of capital stock
or other equity securities of the Company representing 25% or more (by voting
power) of the outstanding capital stock of the Company or a Significant
Subsidiary on a fully diluted basis or any tender or exchange offer that if
consummated would result in any person, together with all affiliates thereof,
beneficially owning shares of capital stock or other equity securities of the
Company or a Significant Subsidiary representing 25% or more (by voting power)
of the outstanding capital stock of the Company on a fully diluted basis, or the
acquisition, purchase or other disposition of 25% or more of the technology,
business or assets of the Company (based on the Company's December 31, 2000
audited consolidated balance sheet) outside the ordinary course of business or
inconsistent with past practice. The term "Superior Proposal" means any bona
fide Acquisition Proposal which is on terms that the Board of Directors of the
Company determines in its good faith judgment (after receipt of the advice of
its financial advisor) provides for consideration which would exceed the value
of the consideration provided for in the Merger, after taking into account all
relevant factors, including any conditions to such Acquisition Proposal, the
timing of the closing thereof, the risk of nonconsummation, the ability of the
person making the Acquisition Proposal to finance the transaction contemplated
thereby and any required governmental or other consents, filings and approvals.

     (c) In addition to the other obligations of the Company set forth in this
Section 5.4, the Company shall promptly advise Parent of any request for
information with respect to any Acquisition Proposal, or any inquiry with
respect to or which is reasonably likely to result in an Acquisition Proposal.

                                      A-31
<PAGE>   151

     Section 5.5 LITIGATION.  The Company shall provide Parent with pertinent
information relating to any litigation against the Company and/or its directors
relating to the transactions contemplated by this Agreement or other litigation,
actions, written claims or written demands, as reasonably requested by Parent
and not otherwise subject to disclosure restrictions. In addition, the Company
shall comply with its material obligations pursuant to the settlement agreement
which relates to the In Re Advanced Health Corporation Securities Litigation
class action lawsuit.

     Section 5.6 MATERIAL CONTRACTS.  Upon the reasonable request of Parent, the
Company shall provide Parent with copies of any requested material contract (as
such term is defined in Item 610(b)(10) of Regulation S-K of the SEC) entered
into by the Company after the date hereof, to the extent not subject to
disclosure restrictions.

     Section 5.7 FURTHER ACTION.  Upon the terms and subject to the conditions
hereof, the Company in good faith shall use all reasonable efforts to take, or
cause to be taken, all actions and to, or cause to be done, all other things
necessary, proper or advisable to consummate and make effective as promptly as
practicable the transactions contemplated by this Agreement, to obtain in a
timely manner all necessary waivers, consents and approvals and to effect all
necessary registrations and filings, and to otherwise satisfy or cause to be
satisfied all conditions precedent to its obligations under this Agreement.

                                   ARTICLE VI

                   COVENANTS OF PARENT AND MERGER SUBSIDIARY

     Section 6.1 LISTING.  Parent shall use its best efforts to cause the Parent
Common Stock to be issued in the Merger and to be issuable upon exercise of
Parent Options and Parent Management Options to be approved for listing on the
NASDAQ-SM, subject to official notice of issuance, as promptly as practicable
after the date hereof, and in any event prior to the Effective Time.

     Section 6.2 INDEMNIFICATION.  (a) For six (6) years after the Effective
Time, Parent and the Surviving Corporation will indemnify and hold harmless
(including advancement of expenses as incurred) the current and former directors
and officers of the Company, (collectively, the "Indemnified Parties") against
any costs or expenses (including reasonable attorneys' fees), judgments, fines,
losses, claims, damages, liabilities and amounts paid in settlement in
connection with any claim, action, suit, proceeding or investigation, whether
civil, criminal, administrative or investigative, arising out of or pertaining
to any facts or events existing or occurring prior to the Effective Time
(including, without limitation, the transactions contemplated by this
Agreement), to the extent provided in the Company's certificate of
incorporation, by-laws and agreements in effect on the date hereof, to the
fullest extent each corporation is permitted under applicable law; provided that
such indemnification shall be subject to any limitation imposed from time to
time under applicable law. Parent will cause to be maintained for a period of
not less than four (4) years from the Effective Time the Company's current
policies of directors' and officers' liability insurance and indemnification
policy to the extent that it provides coverage for events occurring at or prior
to the Effective Time (the "D&O Insurance") for all persons who are directors
and officers of the Company on the date of this Agreement, so long as the annual
premium therefor is not more than two hundred percent (125%) (such 125% amount,
the "Maximum Premium") of the amount per annum the Company paid for such D&O
Insurance in its last full fiscal year, which

                                      A-32
<PAGE>   152

amount has been disclosed to Parent, on terms and conditions substantially
similar to the existing D&O Insurance. If the existing D&O Insurance cannot be
maintained, expires or is terminated or canceled during such six-year period,
Parent will use reasonable efforts to cause to be obtained with reputable and
financially sound carriers policies containing at least the same coverage and
amounts containing terms and conditions which are no less advantageous for the
remainder of such period for an annualized premium which is more than the
Maximum Premium of the amount per annum the Company paid in its last full fiscal
year. If such insurance coverage cannot be obtained at all, or can only be
obtained at an annual premium which is more than the Maximum Premium, Parent
shall maintain the most advantageous policies of directors' and officers'
insurance obtainable for an annual premium equal to the Maximum Premium;
provided, further, if such insurance coverage cannot be obtained at all, Parent
shall purchase all available extended reporting periods with respect to
preexisting insurance in an amount that, together with all other insurance
purchased pursuant to this Section, does not exceed the Maximum Premium. The
Company represents to Parent that the annual premium paid for the 2000 Policy
was $76,213. Parent agrees, and will cause the Surviving Corporation, not to
take any action that would have the effect of limiting the aggregate amount of
insurance coverage required to be maintained for the individuals referred to in
this Section. It is understood that, unless made by a court, any determination
as to whether a person seeking indemnification pursuant to this Section 6.2 has
met any applicable legal standard for indemnification shall be made by a
committee consisting of at least two of Parent's independent directors.

     (b) In the event Parent or the Surviving Corporation or any of their
successors or assigns (i) consolidates with or merges into any other Person and
shall not be the continuing or surviving corporation or entity of such
consolidation or merger, or (ii) transfers or conveys all or substantially all
of its properties and assets to any Person, then, and in each such case, to the
extent necessary to effectuate the purposes of this Section 6.2, proper
provision shall be made so that the successors and assigns of Parent and the
Surviving Corporation assume all of the obligations set forth in this Section
6.2; provided that, in the case of any such assignment by Parent or the
Surviving Corporation, Parent and the Surviving Corporation shall remain liable
for all of their respective obligations under this Agreement.

     (c) The provisions of this Section are intended to be for the benefit of,
and shall be enforceable by, each of the Indemnified Parties, their heirs, their
representatives and assigns.

     Section 6.3 OBLIGATIONS OF MERGER SUBSIDIARY.  Parent will take all action
necessary to cause Merger Subsidiary to perform its obligations under this
Agreement (including ensuring that Merger Subsidiary will at the appropriate
times have sufficient shares of Parent Common Stock and funds to consummate the
Merger in accordance with the terms hereof) and to consummate the Merger on the
terms and conditions set forth in this Agreement.

     Section 6.4 VOTING OF SHARES.  Parent and Merger Subsidiary agree to make a
quorum and vote all shares of Company Common Stock beneficially owned by them in
favor of approval and adoption of this Agreement and the Merger at the Company
Stockholders Meeting.

     Section 6.5 EMPLOYEES.  (a) Parent agrees to honor in accordance with their
terms all Benefit Plans and all employment and severance agreements in each case
listed in Sections 4.1(j) and 6.5 of the Company Disclosure Schedule (or filed
as exhibits to the

                                      A-33
<PAGE>   153

Company SEC Documents), and all accrued benefits vested thereunder; it being
understood and agreed that nothing in this Section 6.5(a) shall prevent Parent
from terminating any Benefit Plan or other agreement in accordance with its
terms.

     (b) Parent agrees to provide employees of the Company and its Subsidiaries
retained by Parent with employee benefits in the aggregate no less favorable
than those benefits provided to Parent's similarly situated employees; provided
that Parent shall be under no obligation to retain any employee or group of
employees of the Company or its Subsidiaries.

     (c) For purposes of all employee benefit plans, programs and arrangements
maintained by or contributed to by Parent and its Subsidiaries (including, after
the Closing, the Surviving Corporation), Parent shall, or shall cause its
Subsidiaries to, cause each such plan, program or arrangement to treat the prior
service with the Company and its affiliates of each person who is an employee or
former employee of the Company or its Subsidiaries immediately prior to the
Closing (a "Company Employee") (to the same extent such service is recognized
under analogous plans, programs or arrangements of the Company or its affiliates
prior to the Closing) as service rendered to Parent or its Subsidiaries, as the
case may be, for purposes of eligibility to participate in and vesting
thereunder (but not benefit accrual); provided, however, that such crediting of
service shall not operate to duplicate any benefit or the funding of such
benefit. Company Employees shall also be given credit for any deductible or
co-payment amounts paid in respect of the plan year in which the Closing occurs,
to the extent that, following the Closing, they participate in any other plan
for which deductibles or co-payments are required. Parent shall also cause each
Parent benefit plan to waive any preexisting condition which was waived under
the terms of any Benefit Plan immediately prior to the Closing or waiting period
limitation which would otherwise be applicable to a Company Employee on or after
the Closing. Parent shall recognize any accrued but unused vacation and
sabbatical time of the Company Employees as of the date of Closing, in
accordance with the terms of such Company policies, and Parent shall provide
such vacation and sabbatical time in accordance with the terms of such Company
policies but in no event will Parent be obligated to extend or enlarge the
benefits available under such Company policies.

     Section 6.6 FURTHER ACTION.  Upon the terms and subject to the conditions
hereof, Parent and Merger Subsidiary in good faith shall use all reasonable
efforts to take, or cause to be taken, all actions and to, or cause to be done,
all other things necessary, proper or advisable to consummate and make effective
as promptly as practicable the transactions contemplated by this Agreement, to
obtain in a timely manner all necessary waivers, consents and approvals and to
effect all necessary registrations and filings, and to otherwise satisfy or
cause to be satisfied all conditions precedent to its obligations under this
Agreement. Without limiting the generality of the foregoing, the board of
directors of Parent shall recommend the issuance of Parent Common Stock issuable
to the holders of Company Common Stock pursuant to this Agreement to holders of
Parent Common Stock and Parent and Merger Subsidiary shall take all necessary
action to (i) cause the Form S-4 to become effective under the Securities Act
and (ii) obtain all state securities and "blue sky" permits and approvals
necessary to consummate the transactions contemplated hereby, all in a timely
manner.

     Section 6.7 ASSUMPTION OF NOTE.  As of the Effective Time, Parent and the
Surviving Corporation hereby expressly assume all of the obligations of the
Company under the 10% Senior Secured Convertible Note issued by Cybear, Inc. to
the Company (the "Cybear Note"), and hereby agrees to be bound by all of the
agreements and covenants of the

                                      A-34
<PAGE>   154

Company under the related Securities Purchase Agreement by and between the
Company and Cybear, Inc., dated as of March 27, 2000, and the related agreements
and documents entered into in connection therewith (collectively, the "Cybear
Agreements"), all in conformity with the respective terms thereof, and Parent
shall take all actions required by the Cybear Agreements necessary to effectuate
the Merger. Without limiting the generality of the foregoing, Parent and the
Surviving Corporation (i) hereby expressly assume all of the obligations of the
Company under the Warrants (as defined in the Cybear Agreements) and shall
deliver to the holder of the Warrants such shares of stock, securities, cash or
other property as such holder shall be entitled to purchase in accordance with
the provisions of the Warrants and (ii) shall take all necessary steps so that
the holder of the Cybear Note shall be entitled to receive, in lieu of the
number of shares of Company Common Stock to which such holder was theretofore
entitled upon the exercise of the conversion privilege, the aggregate number of
shares of Parent Common Stock that such holder would have been entitled to
receive as a result of the Merger if, at the Effective Time, such holder had
been the holder of the number of shares of Company Common Stock to which such
holder was theretofore entitled upon conversion of the Cybear Note; such number
of shares of Parent Common Stock to be subject to adjustment thereafter in
accordance with the provisions, as nearly as may be possible, as those contained
in the Cybear Agreements. At or prior to the Effective Time, Parent shall take
all corporate action necessary to reserve for issuance a sufficient number of
shares of Parent Common Stock for delivery upon conversion of the Cybear Note
and exercise of the Warrants, all in conformity with the Cybear Agreements.

     Section 6.8 STATE TAKEOVER STATUTES.  f any takeover statute is or may
become applicable to the Merger or the other transactions contemplated by this
Agreement, Parent and its board of directors shall grant such approvals and take
such actions (or cause such actions to be taken) as are necessary so that such
transactions may be consummated as promptly as practicable on the terms
contemplated by this Agreement or by the Merger and otherwise act to eliminate
or minimize the effects of such statute or regulation on such transactions.

                                  ARTICLE VII

                             ADDITIONAL AGREEMENTS

     Section 7.1 SHAREHOLDER APPROVAL; PREPARATION OF S-4 AND JOINT PROXY
STATEMENT. (a) As promptly as reasonably practicable following the date hereof,
Parent and the Company shall cooperate in preparing and filing with the SEC
mutually acceptable proxy materials which shall constitute the joint proxy
statement/prospectus relating to the matters to be submitted to the holders of
Company Common Stock at the Company Stockholders Meeting and the matters to be
submitted to the holders of Parent Common Stock at the Parent Stockholders
Meeting (such proxy statement/prospectus, and any amendments or supplements
thereto, being herein referred to as the "Joint Proxy Statement"). The Company
and Parent each shall, upon request by the other, furnish the other with all
information concerning itself, its Subsidiaries, directors, officers and holders
of Parent Common Stock and such other matters as may be reasonably necessary or
advisable in connection with the Joint Proxy Statement, the Form S-4 or any
other statement, filing, notice or application made by or on behalf of Parent,
the Company or any of their respective Subsidiaries to any third party and/or
any Governmental Entity in connection with the Merger and the transactions
contemplated by this Agreement. Parent shall prepare and file with the SEC a
registration statement on Form S-4 with respect to
                                      A-35
<PAGE>   155

the issuance of Parent Common Stock in the Merger (such Form S-4, and any
amendments or supplements thereto, the "Form S-4"). The Joint Proxy Statement
will be included as a prospectus in and will constitute a part of the Form S-4
as Parent's prospectus. Each of Parent and the Company shall use its best
efforts to have the Form S-4 declared effective by the SEC and to keep the Form
S-4 effective as long as is necessary to consummate the Merger and the other
transactions contemplated thereby. Parent and the Company shall, in accordance
with applicable law and their certificates of incorporation, as promptly as
practicable after receipt thereof, provide the other party copies of any written
comments of the SEC and advise the other party of any oral comments of the SEC,
with respect to the Joint Proxy Statement or Form S-4. The parties shall
cooperate and provide the other with a reasonable opportunity to review and
comment on any amendment or supplement to the Joint Proxy Statement and the Form
S-4 prior to filing such with the SEC, and will provide each other with a copy
of all such filings made with the SEC. Notwithstanding any other provision
herein to the contrary, no amendment or supplement (including by incorporation
by reference) to the Joint Proxy Statement or the Form S-4 shall be made without
the approval of both parties, which approval shall not be unreasonably withheld
or delayed. Parent shall also take any action (other than qualifying to do
business in any jurisdiction in which it is not now so qualified or to file a
general consent to service of process) required to be taken under any applicable
state securities laws in connection with the issuance of Parent Common Stock in
the Merger. Parent will advise the Company, promptly after it receives notice
thereof, of the time when the Form S-4 has become effective or any supplement or
amendment has been filed, the issuance of any stop order, the suspension of the
qualification of the Parent Common Stock issuable in connection with the Merger
for offering or sale in any jurisdiction, or any request by the SEC for
amendment of the Form S-4 or comments thereon and responses thereto or requests
by the SEC for additional information. Each party will advise the other,
promptly after it receives notice thereof, of any request by the SEC for the
amendment of the Joint Proxy Statement or comments thereon and responses thereto
or requests by the SEC for additional information. If at any time prior to the
Effective Time any information relating to the Company or Parent, or any of
their respective affiliates, officers or directors, should be discovered by the
Company or Parent which should be set forth in an amendment or supplement to
either of the Joint Proxy Statement or the Form S-4, so that any of such
documents would not include any misstatement 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, the party which
discovers such information shall promptly notify the other parties hereto and an
appropriate amendment or supplement describing such information shall be
promptly filed with the SEC and, to the extent required by law, disseminated to
the holders of Company Common Stock.

     (b) The Company shall establish, prior to or as soon as practicable
following the date hereof, a record date (which shall be prior to or as soon as
practicable following the date upon which the Form S-4 becomes effective) for,
duly call, give notice of, convene and hold a meeting of the holders of Company
Common Stock (the "Company Stockholders Meeting") for the purpose of considering
and taking action upon this Agreement and the Merger and, in case the requisite
approval of the Company's stockholders to approve an amendment to the Company's
Certificate of Incorporation to increase the number of authorized shares from
15,000,000 to 30,000,000 (the "Authorized Share Approval") is not obtained at
the Company's Annual Meeting of Stockholders, for the purpose of considering and
taking action to obtain the Authorized Share Approval, and (with the consent of
Parent) such other matters as may in the reasonable judgment of the Company

                                      A-36
<PAGE>   156

be appropriate for consideration at the Company Stockholders Meeting. Once the
Company Stockholders Meeting has been called and noticed, the Company shall not
postpone or adjourn the Company Stockholders Meeting (other than for the absence
of a quorum) without the consent of Parent. Subject to the Company's right under
this Agreement to withdraw or modify its recommendation to holders of Company
Common Stock to approve and adopt this Agreement (the "Recommendations"), the
Board of Directors of the Company shall include in the Form S-4 and the Joint
Proxy Statement a copy of the Recommendations as such Recommendations pertain to
the Merger and this Agreement. Notwithstanding the foregoing, the Board of
Directors of the Company shall submit this Agreement and the Merger for approval
to the holders of Company Common Stock whether or not the Board of Directors of
the Company determines in accordance with its fiduciary duties after the date
hereof that this Agreement and the Merger are no longer advisable and recommends
that the holders of Company Common Stock reject it. Unless the Board of
Directors of the Company has withdrawn its recommendation of this Agreement and
the Merger in compliance with this Section 7.1, the Company shall use its
reasonable best efforts to solicit from holders of Company Common Stock proxies
in favor of this Agreement and the Merger and shall take all other actions
necessary or advisable to secure the vote or consent of holders of Company
Common Stock required by Delaware Law to effect the Merger.

     (c) Parent shall establish, prior to or as soon as practicable following
the date hereof, a record date (which shall be prior to or as soon as
practicable following the date upon which the Form S-4 becomes effective) for,
duly call, give notice of, convene and hold a meeting of holders of Parent
Common Stock (the "Parent Stockholders Meeting") for the purpose of considering
and taking action upon the issuance of Parent Common Stock in the Merger and, if
the Parent Stockholders Meeting is the Parent's Annual Meeting of Stockholders,
any such other matters as may in the reasonable judgment of Parent be
appropriate for consideration at the Parent Stockholders Meeting.

     Section 7.2 REASONABLE EFFORTS; NOTIFICATION.  (a) Upon the terms and
subject to the provisions hereof, each of Parent and the Company shall cooperate
with the other party in connection with any investigation or other inquiry of
any Governmental Entity with respect to the Merger or the other transactions
contemplated hereby, and each party shall promptly inform the other party of any
communication with, and any proposed understanding, undertaking, or agreement
with, any Governmental Entity regarding the Merger or such other transactions.
Neither party shall participate in any meeting with any Governmental Entity in
respect of any such filings, investigation, or other inquiry without giving the
other party notice of the meeting and, to the extent permitted by such
Governmental Entity, the opportunity to attend and participate. Subject to
applicable laws relating to the exchange of information, Parent and the Company
shall have the right to review in advance, and to the extent reasonably
practicable each will consult the other on, all the information relating to the
other and its Subsidiaries, that appear in any filing made with, or written
materials submitted to, any third party or any Governmental Entity in connection
with the transactions contemplated by this Agreement; provided, however, that
with respect to documents that one party reasonably believes should not be
disclosed to the other party, such party shall furnish those documents to
counsel for the other party pursuant to a mutually satisfactory confidentiality
agreement. In exercising the foregoing right, each of the Company and Parent
shall act reasonably and as promptly as reasonably practicable.

<PAGE>   157

     (b) Upon the terms and subject to the provisions hereof, each of the
parties agrees to use all reasonable efforts to take, or cause to be taken, all
actions, and to do, or cause to be done, and to assist and cooperate with the
other parties in doing, all things necessary, proper or advisable on its part

     any portion of the business or assets of the Company and its Subsidiaries,

     Adverse Effect shall be true and correct in any respect as of the date of

     have a Company Material Adverse Effect; and

     Common Stock representing not more than 900,000 shares of Company Common
     Stock, have not (i) delivered to the Company, prior to the Company

     date, in which case as of such date); provided, however, that,
     notwithstanding anything herein to the contrary, this Section 8.3 (b) shall

The Board of Directors
AHT Corporation

Tarrytown, New York 10591

Gentlemen:

     You have requested our opinion as to the fairness from a financial point of
view to the holders of the outstanding shares of common stock (the "AHT Common
Stock") of AHT Corporation ("AHT") of the consideration to be received by such
shareholders in connection with the merger (the "Proposed Transaction") of AHT
Acquisition Corp. ("Merger Sub"), a wholly owned subsidiary of Bioshield
Technologies, Inc. ("BioShield"), pursuant to an Agreement and Plan of Merger
among BioShield, Merger Sub and AHT, dated as of June 30, 2000 (together with
the related Exhibits and Schedules, the "Agreement").

     We understand that the terms of the Agreement provide, among other things,
that each issued and outstanding share of AHT Common Stock will be converted
into the right to receive the number of shares of common stock of BioShield
("BioShield Common Stock") equal to $1.75 divided by the Average Closing Bid
Price (as defined in the Agreement), but that in no event will the number of
shares of BioShield Common Stock be less than 0.09722 or more than 0.29167, all
as more fully set forth in the Agreement. For the purposes of our opinion, we
have assumed with your permission that the Proposed Transaction will qualify as
a tax-free reorganization under the U.S. Internal Revenue Code of 1986, as
amended, and that the Proposed Transaction will be accounted for as a purchase
transaction.

     Chase Securities Inc. ("Chase"), as part of its investment banking
services, is regularly engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, strategic transactions,
corporate restructurings, negotiated underwritings, secondary distributions of
listed and unlisted securities, private placements and valuations for corporate
and other purposes. We have acted as a financial advisor to you in connection
with the Proposed Transaction, and we will receive a fee for our services, which
include the rendering of this opinion. We will also receive a fee upon
consummation of the Proposed Transaction.

     In the past, we have provided investment banking and other financial
advisory services to AHT and have received fees for rendering these services. In
the ordinary course of business, Chase may actively trade in the equity and
derivative securities of AHT for its

                                       B-1

own account and for the accounts of its customers and, accordingly, may at any
time hold a long or short position in such securities. Chase may in the future
provide additional investment banking or other financial advisory services to
AHT.

     In connection with our review of the Proposed Transaction, and in arriving
at our opinion, we have, among other things:

          (i) reviewed the publicly available financial statements of BioShield
     for recent years and interim periods to date and certain other relevant
     financial and operating data of BioShield (including its capital structure)
     made available to us from published sources and from the internal records
     of BioShield;

          (ii) reviewed certain internal financial and operating information,
     including certain projections, relating to BioShield prepared by the
     management of BioShield;

          (iii) discussed the business, financial condition and prospects of
     BioShield with certain members of its senior management;

          (iv) reviewed the publicly available financial statements of AHT for
     recent years and interim periods to date and certain other relevant
     financial and operating data of AHT made available to us from published
     sources and from the internal records of AHT;

          (v) reviewed certain internal financial and operating information,
     including certain projections, relating to AHT prepared by the senior
     management of AHT;

          (vi) discussed the business, financial condition and prospects of AHT
     with certain members of senior management;

          (vii) reviewed the recent reported prices and trading activity for the
     common stocks of BioShield and AHT and compared such information and
     certain financial information for BioShield and AHT with similar
     information for certain other companies engaged in businesses we consider
     comparable;

          (viii) reviewed the financial terms, to the extent publicly available,
     of certain merger and acquisition transactions;

          (ix) reviewed the Agreement; and

          (x) performed such other analyses and examinations and considered such
     other information, financial studies, analyses and investigations and
     financial, economic and market data as we deemed relevant.

     In rendering our opinion, we have assumed and relied upon the accuracy and
completeness of all of the information concerning BioShield or AHT considered in

                                       B-2

connection with our review of the Proposed Transaction, and we have not assumed
any responsibility for independent verification of, and did not independently
verify, such information. We have not undertaken any independent valuation or
appraisal of any of the assets or liabilities of BioShield or AHT, nor have we
conducted a physical inspection of the properties, facilities or other assets of
either company. With respect to the financial forecasts and projections made
available to us and used in our analysis, we have assumed that they reflect the
best currently available estimates and judgments of the managements of BioShield
and AHT of the expected future financial performances of BioShield and AHT. In
rendering our opinion, we express no view as to the reasonableness of such
forecasts and projections or the assumptions on which they are based. We have
assumed with your consent for purposes of our analysis that the value of the
BioShield Common Stock offered to stockholders of AHT in the Proposed
Transaction is equal to the closing trading price of BioShield Common Stock as
of June 29, 2000. For purposes of this opinion, we have assumed that neither
BioShield nor AHT is a party to any pending transactions, including external
financings, recapitalizations or material merger discussions, other than the
Proposed Transaction and those activities undertaken in the ordinary course of
conducting their respective businesses; provided, however, Bioshield management
has described to us a potential acquisition that may be consummated in the near
term, and we have assumed, with your consent, that such transaction will be
completed on reasonable commercial terms. Our opinion is necessarily based upon
market, economic, financial and other conditions as they exist and can be
evaluated as of the date of this letter and any change in such conditions would
require a reevaluation of this opinion. We express no opinion as to the price at
which AHT Common Stock or BioShield Common Stock will trade subsequent to the
date hereof. In rendering this opinion, we have assumed that the Proposed
Transaction will be consummated substantially on the terms discussed in the
Agreement, without any waiver of any material terms or conditions by any party
thereto.

     It is understood that this letter is for the information of the Board of
Directors of AHT only and may not be used for any other purpose without our
prior written consent; provided, however, that this letter may be reproduced in
full in any proxy statement filed by the Company in connection with the Proposed
Transaction and that we consent to any description of or reference to this
opinion therein in form and substance reasonably acceptable to us and our legal
counsel. This letter does not constitute a recommendation to any stockholder of
AHT Common Stock as to whether such stockholder should vote in favor of the
Proposed Transaction.

     Based upon and subject to the foregoing and after considering such other
matters as we deem relevant, we are of the opinion that as of the date hereof
the consideration to be received by the holders of the Common Stock in the
Proposed Transaction is fair to such holders from a financial point of view. We
express no opinion, however, as to the adequacy of any consideration received in
the Proposed Transaction by BioShield or any of its affiliates.

                                          Very truly yours,

The Board of Directors
BioShield Technologies, Inc.
5655 Peachtree Parkway
Norcross, GA 30093

Members of the Board:

     We understand that BioShield Technologies, Inc., a Georgia corporation
("Bioshield") and AHT Corporation, a Delaware Corporation ("AHT") have entered
into an Agreement and Plan of Merger dated June 30, 2000 (the "Agreement")
pursuant to which a wholly owned subsidiary of BioShield will merge with AHT,
with AHT as the surviving corporation in the merger (resulting in AHT becoming a
wholly owned subsidiary of BioShield) (the "Merger"). In the Merger, each share
of AHT common stock (other than shares held in treasury and shares held by
BioShield) issued and outstanding immediately prior to the Merger shall be
converted into the right to receive such number of shares of BioShield common
stock (the "Exchange Ratio") as shall be determined by dividing $1.75 by the
average closing bid price of BioShield common stock for the ten consecutive
trading days ending on the third trading day prior to the date which is the
later of (i) the date of the meeting of holders of AHT common stock to approve
the Merger, and (ii) the date of the meeting of holders of BioShield common
stock to approve certain matters relating to the Merger, provided, however, that
such Exchange Ratio shall not exceed .29167 nor be less than .09722. The terms
and conditions of the Merger are more fully set forth in the Agreement.

     You have requested our opinion, as investment bankers, as to the fairness,
from a financial point of view, to the holders of BioShield common stock of the
consideration to be paid to the holders of AHT common stock (the
"Consideration") in the Merger. Our opinion addresses only the fairness, from a
financial point of view, of the Consideration, and we do not express any views
on any other terms of the Merger. Specifically, we have not been requested to
opine as to, and our opinion does not in any manner address, BioShield's
underlying business decision to proceed with or effect the Merger.

     In arriving at our opinion we have:

          (i) reviewed the Agreement dated June 30, 2000;

          (ii) held discussions with members of senior management of BioShield
     and AHT regarding their respective past and current business operations and
     their financial conditions and future prospects;

          (iii) reviewed historical financial and business information provided
     to us by the management of BioShield and the management of AHT;

          (iv) reviewed internally prepared financial projections of BioShield
     and AHT furnished to us by the managements of BioShield and AHT,
     respectively;

          (v) reviewed the historical stock prices and trading volumes of
     BioShield's and AHT's common stock;

          (vi) compared the respective financial performance of AHT and
     BioShield with that of certain other publicly traded companies comparable
     to that of each of BioShield and AHT respectively;

The Board of Directors
BioShield Technologies, Inc.
5655 Peachtree Parkway
Norcross, GA 30093

          (vii) reviewed the financial terms, to the extent publicly available,
     of certain transactions which we considered comparable to the Merger; and

          (viii) conducted such other analyses and reviewed such other
     information as we deemed appropriate for the purpose of our opinion.

     Gruntal, as part of its investment banking business, is continually engaged
in the valuation of businesses and their securities in connection with mergers
and acquisitions, negotiated underwritings, distributions of listed and unlisted
securities, private placements and financial valuations for corporate purposes.
We have acted as financial advisor to BioShield in connection with the Merger
and will receive fees and other compensation for our services. In the past,
Gruntal has provided financial advice to both BioShield and AHT and has received
fees for rendering these services. In addition, in the ordinary course of our
business, Gruntal may actively trade BioShield's and AHT's common stock for
Gruntal's account and for the accounts of customers, and accordingly, may at any
time hold a long or short position in such security.

     In the course of our review, we have relied upon and assumed with your
consent, the accuracy and completeness of all the information furnished to us by
BioShield and AHT and have not attempted an independent verification thereof. We
have not made nor obtained any independent evaluations or appraisals of the
assets or liabilities of AHT or BioShield, including, but not limited to,
liabilities arising from or connected with any pending or future litigation to
which BioShield or AHT is or may become a party. With respect to the financial
projections furnished to us or discussed by us with the management of BioShield
and AHT respectively, we have assumed that they have been reasonably prepared
and reflect the best currently available respective estimates and judgements of
BioShield's and AHT's management as to the expected future results of
operations, synergies and financial condition of BioShield and AHT respectively
to which such analyses and forecasts relate, and we have assumed that such
expected future results of operations, synergies and strategic benefits will be
realized as described by such management. The inability of BioShield and AHT to
realize such expected future results of operations, synergies and strategic
benefits could affect the opinion herein, and we express no view as to whether
such future results of operations, synergies and strategic benefits will
actually be realized. We have also assumed that the transaction will have the
tax consequences described in the Agreement and in discussions with BioShield.

     Our opinion is necessarily based on economic, market and other conditions
as in effect on, and the information made available to us as of, the date
hereof. It should be understood that subsequent developments including, without
limitation, any changes to the terms or conditions of the Merger may affect this
opinion and that we do not have any obligation to update, revise, or reaffirm
this opinion. We are expressing no opinion herein as to the price at which
BioShield common stock will trade at any future date. We have also assumed that
in the course of obtaining the necessary regulatory or other consents or
approvals (contractual or otherwise) for the Merger, no material restrictions,
including any divestiture requirements or amendments or modifications to the
Merger, will be imposed.

     Based upon and subject to the foregoing, including the various assumptions
and limitations set forth herein, we are of the opinion that, as of the date
hereof, the Consideration is fair, from a financial point of view, to the
holders of BioShield common stock.

     This opinion is for the use and benefit of the Board of Directors of
BioShield in connection with and for the purpose of its evaluation of the
Merger. This opinion does not constitute a recommendation to engage in the
Merger or a recommendation to any shareholder of BioShield as to how such
shareholder should vote on the Merger or any matter related thereto.

                              AMENDED AND RESTATED
                           ARTICLES OF INCORPORATION
                                       OF
                          BIOSHIELD TECHNOLOGIES, INC.

                                       I.

     The name of the Corporation is BioShield Technologies, Inc.

                                      II.

     (a) The Corporation hereby designates that the total number of shares of
capital stock which the Corporation has authority to issue is 50,000,000,
divided into 40,000,000 shares of "Common Stock," no par value, and 10,000,000
shares of capital stock, no par value, to be designated as "Preferred Stock."

     (b) Subject to any preferences of any Preferred Stock then outstanding, the
shares of Common Stock shall have unlimited voting rights and shall be entitled
to receive the net assets of the Corporation upon dissolution.

     (c) Subject to the provisions of these Articles of Incorporation and to the
provisions of the Georgia Business Corporation Code (the "Corporation Code"),
the Board of Directors may determine (i) the number, designation, preferences,
limitations and relative rights of any class of shares of Preferred Stock and
(ii) the number, preferences, limitations and relative rights of one or more
series of Preferred Stock within a class, prior to the issuance of any shares of
such class or series. Any of the voting powers, preferences, rights,
qualifications, limitations or restrictions of a class or series of Preferred
Stock, or the holders thereof, may be made dependent upon facts ascertainable
outside these Articles of Incorporation.

                                      III.

     (a) In discharging the duties of their respective positions and in
determining what is believed to be in the best interests of the Corporation, the
Board of Directors, committees of the Board of Directors, and individual
directors, in addition to considering the effects of any action on the
Corporation or its shareholders, may consider the interests of the employees,
customers, suppliers and creditors of the Corporation and its subsidiaries, the
communities in which offices or other establishments of the Corporation and its
subsidiaries are located, and all other factors such directors consider
pertinent; provided, however, that this paragraph shall be deemed solely to
grant discretionary authority to the directors and shall not be deemed to
provide to any constituency any right to be considered.

                                       D-1
<PAGE>   174

     (b) The following provisions are inserted for the management of the
business and the conduct of the affairs of the Corporation, and for further
definition, limitation and regulation of the powers of the Corporation and of
the Board of Directors and shareholders:

          (i) The business and affairs of the Corporation shall be managed by or
     under the direction of the Board of Directors;

          (ii) The Board of Directors shall consist of not less than three nor
     more than twenty-one directors. The exact number of directors shall be
     determined from time to time by resolution adopted by the affirmative vote
     of a majority of the Board of Directors. The directors shall be divided
     into three classes, designated Class I, Class II and Class III. Each class
     shall consist, as nearly as may be possible, of one-third of the total
     number of directors constituting the entire Board of Directors. The first
     member of Class I shall be Michel M. Azran, the first member of Class II
     shall be Carl T. Garner, and the first member of Class III shall be Timothy
     C. Moses and Jacques Elfersy. The first directors serving as members of
     Class I shall hold office until the annual meeting of shareholders to be
     held in 1998, the first director serving as members of Class II shall hold
     office until the annual meeting of shareholders to be held in 1999, and the
     first directors serving as members of Class III shall hold office until the
     annual meeting of shareholders to be held in 2000. At each annual meeting
     of shareholders, successors to the class of directors whose term expires at
     that annual meeting shall be elected for a three-year term. Directors shall
     serve until the expiration of their terms and until their successors have
     been elected and qualify, subject to the director's prior death,
     resignation, disqualification or removal from office. If the number of
     directors is changed in accordance with the terms of these Articles of
     Incorporation, any increase or decrease shall be apportioned among the
     classes so as to maintain the number of directors in each class as nearly
     equal as possible. Any vacancy on the Board of Directors that results from
     a newly created directorship, and any other vacancy occurring on the Board
     of Directors, shall be filled by the affirmative vote of a majority of the
     Board of Directors then in office, although less than a quorum, or by a
     sole remaining director. A director of any class elected by the Board of
     Directors to fill a vacancy shall hold office until the next annual meeting
     of shareholders. A director of any class elected by the shareholders to
     fill a vacancy shall hold office for a term that shall coincide with the
     remaining term of that class. In no case will a decrease in the number of
     directors shorten the term of any incumbent director. The election of
     directors need not be by written ballot unless the Corporation's Bylaws so
     require.

     (c) The shareholders shall not have the right to remove any one or all of
the directors except for cause and by the affirmative vote of the holders of at
least 66 and  2/3% of the outstanding shares of the capital stock of the
Corporation entitled to vote generally in the election of directors ("Voting
Stock") that are not beneficially owned (as defined in (h)(x) below) by any
Interested Shareholder (as defined in (h)(iii) below). Notwithstanding the
foregoing, whenever the holders of any one or more classes or series of
preferred stock that may be authorized in the future and issued by the
Corporation shall have the right, voting separately by class or series, to elect
directors at an annual or special meeting of shareholders, the election, term of
office, filling of vacancies and other features of such directorships shall be
governed by the terms of that class or series ("Preferred Stock Designation") as
determined by the shareholders or by the Board of Directors, and

                                       D-2
<PAGE>   175

such directors so elected shall serve annual terms and shall not be divided into
classes except as expressly provided by the Preferred Stock Designation for that
class or series.

     (d) In addition to the powers and authority herein or by statute expressly
conferred upon them, the directors are hereby empowered to exercise all such
powers and do all such acts and things as may be exercised or done by the
Corporation, subject, nevertheless, to the provisions of the Corporation Code,
these Articles of Incorporation and any Bylaws adopted by the shareholders;
provided, however, that no Bylaws hereafter adopted by the shareholders shall
invalidate any prior act of the directors which would have been valid if such
Bylaws had not been adopted.

     (e) No action shall be taken by shareholders of the Corporation except at
an annual or special meeting of shareholders of the Corporation or by unanimous
written consent and the right of shareholders to act by less than unanimous
written consent in lieu of a meeting is specifically denied. Unless otherwise
prescribed by law, special meetings of shareholders, for any purpose or
purposes, may be called only by (i) the Chairman of the Board of Directors of
the Corporation, (ii) the President of the Corporation, (iii) the Secretary of
the Corporation at the request in writing of a majority of the Board of
Directors, or (iv) the Secretary of the Corporation at the request in writing of
the holders of at least ten percent (10%) of the outstanding shares of Voting
Stock.

     (f) The Board of Directors shall have concurrent power with the
shareholders as set forth in these Articles of Incorporation to make, alter,
amend, change, add to or repeal the Bylaws of the Corporation. The Board of
Directors may amend the Bylaws of the Corporation upon the affirmative vote of
the number of directors required, under the terms of the Bylaws, to take action
of the Board of Directors; provided, however, that any amendment, addition or
repeal of any provision of the Bylaws regarding indemnification of the
directors, officers, employees or agents of the Corporation shall require the
affirmative vote of a majority of the Disinterested Directors. Shareholders may
not amend the Bylaws of the Corporation except upon the affirmative vote of the
holders of at least 66 and  2/3% of the outstanding shares of Voting Stock that
are not beneficially owned by any Interested Shareholder, except that the
affirmative vote of the holders of only a majority of the outstanding Voting
Stock shall be required to approve any amendment to the Bylaws approved by the
Board of Directors if at least two-thirds ( 2/3) of the directors then in office
are Disinterested Directors.

     (g) For purposes of this Article III:

          (i) The term "person" shall mean any individual, firm, group,
     corporation, partnership, association, trust or other entity (as such terms
     were used on July 15, 1997 for purposes of Regulation 13D-G under the 1934
     Act).

          (ii) The term "Interested Shareholder" shall mean:

             (A) any person (other than the Corporation, any Subsidiary or any
        employee benefit plan of the Corporation or any Subsidiary) who or
        which, together with its "Affiliates" and "Associates" (as such terms
        were defined on July 15, 1997 in Rule 12b-2 promulgated under the 1934
        Act) and any persons acting in concert with them, is the beneficial
        owner of fifteen percent (15%) or more of the outstanding shares of the
        Voting Stock;

             (B) any Affiliate, Associate, representative or person acting in
        concert with any person described in the foregoing subparagraph (iii)(A)
        of this Section (h);

                                       D-3
<PAGE>   176

             (C) any Affiliate of the Corporation that, at any time within the
        two-year period immediately prior to the date in question, was the
        beneficial owner, directly or indirectly, of fifteen percent (15%) or
        more of the Voting Stock; and

             (D) any person who is an assignee of, or has otherwise succeeded
        to, any shares of Voting Stock that were at any time within the two-year
        period immediately prior to the date in question, beneficially owned by
        any Interested Shareholder, if such assignment or succession occurred in
        the course of a transaction or series of transactions not involving a
        "public offering," within the meaning of the Securities Act of 1933, as
        amended. Without limitation, any person that has the right to acquire
        any shares of Voting Stock pursuant to any agreement, or upon exercise
        of conversion rights, warrants, or options, or otherwise, shall be
        deemed a beneficial owner of such shares for purposes of determining
        whether such person or group, individually or together with its
        Affiliates and Associates, is an Interested Shareholder, but the number
        of shares deemed to be outstanding pursuant to this Paragraph (iii) of
        Section (h) shall not include any other shares of Voting Stock that may
        be issuable pursuant to any agreement, arrangement, or understanding, or
        upon exercise of conversion rights, warrants, or options, or otherwise;
        provided, however, that the term "Interested Shareholder" shall not
        include any person who has beneficially owned, together with its
        Affiliates and Associates and any persons acting in concert with them,
        at least fifteen percent (15%) or more of the outstanding shares of the
        Voting Stock at all times since July 15, 1997.

          (iii) The term "Subsidiary" shall mean any corporation of which a
     majority of any class of equity security is owned, directly or indirectly,
     by the Corporation; provided, however, that for the purposes of the
     definition of an Interested Shareholder set forth in Paragraph (c) of this
     Section 6.2, the term "Subsidiary" shall mean only a corporation of which a
     majority of each class of equity security is owned, directly or indirectly,
     by the Corporation.

          (iv) The term "Disinterested Director" shall mean any person who:

             (A) is not affiliated, associated or otherwise a representative of
        or acting in concert with an Interested Shareholder and who was a member
        of the Corporation's Board of Directors prior to the time the Interested
        Shareholder became an Interested Shareholder; or

             (B) any successor to a Disinterested Director who is not affiliated
        with an Interested Shareholder and who was (1) elected as a director or
        (11) recommended (and continued to be recommended at all times before
        such person's initial election as a director) for election as a director
        by the shareholders by a majority of the Board of Directors, if at least
        two-thirds ( 2/3) of the directors were Disinterested Directors at the
        time of such election or recommendation.

          (v) The term "beneficial owner" shall have the meaning set forth as of
     July 15, 1997 in Rule 13d-3 promulgated under the 1934 Act and a person
     shall "beneficially own" securities of which it is the beneficial owner;

     (h) In the event any paragraph (or portions thereof) of this Article III
shall be found to be invalid, prohibited, or unenforceable for any reason, the
remaining provisions (or portions thereof) of this Article III shall be deemed
to remain in full force and effect and shall be construed as if such invalid,
prohibited, or unenforceable provisions had been

                                       D-4
<PAGE>   177

stricken herefrom or otherwise rendered inapplicable, it being the intent of the
Corporation and its shareholders that each remaining provision (or portion
thereof) of this Article III remain to the fullest extent permitted by law,
applicable and enforceable as to all shareholders, including Interested
Shareholders, notwithstanding any such finding.

     (i) A majority of the Board of Directors, if at least two-thirds ( 2/3) are
Disinterested Directors, shall have the power and duty to determine, on the
basis of information known to them after reasonable inquiry, all facts necessary
to determine compliance with this Article III, including, without limitation,
(i) whether a person is an Interested Shareholder; (ii) the number of shares of
Voting Stock beneficially owned by any person, and (iii) whether a person is
affiliated, associated, a representative of or otherwise acting in concert with,
another person.

     (j) Nothing contained in this Article III shall be construed to relieve any
Interested Shareholder from any fiduciary obligation imposed by law.

                                      IV.

     (a) A director of the Corporation shall not be personally liable to the
Corporation or its shareholders for monetary damages for breach of duty of care
or other duty as a director, except for liability (i) for any appropriation, in
violation of his duties, of any business opportunity of the Corporation; (ii)
for acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law; (iii) of the types set forth in Section 14-2-832
of the Corporation Code; or (iv) for any transaction from which the director has
derived an improper personal benefit. The provisions of this Article shall not
apply with respect to acts or omissions occurring prior to the effective date of
this Article.

     (b) Any repeal or modification of the provisions of this Article by the
shareholders of the Corporation shall be prospective only, and shall not
adversely affect any limitation on the personal liability of a director of the
Corporation with respect to any act or omission occurring prior to the effective
date of such repeal or modification.

     (c) If the Corporation Code hereafter is amended to authorize the further
elimination or limitation of the liability of directors, then the liability of a
director of the Corporation, in addition to the limitation on personal liability
provided herein, shall be limited to the fullest extent permitted by the amended
Corporation Code.

     (d) In the event that any of the provisions of this Article (including any
provisions within a single sentence) is held by a court of competent
jurisdiction to be invalid, void or otherwise unenforceable, the remaining
provisions are severable and shall remain enforceable to the fullest extent
permitted by law.

                                       V.

     The Corporation reserves the right to amend, alter or repeal any provision
contained in these Articles of Incorporation. Amendments, alterations or repeals
of any provision of these Articles of Incorporation other than Article III or
this Article V shall be effected only by the affirmative vote of the holders of
a majority of the shares entitled to vote thereon and of a majority of the
shares of each class entitled to vote as a class thereon, as prescribed in the
Corporation Code. Notwithstanding any other provisions of these Articles

                                       D-5
<PAGE>   178

of Incorporation or the Corporation's Bylaws or any provision of law that
otherwise might permit a lesser vote or no vote, but in addition to any
affirmative vote of the holders of any particular class or series of stock
required by law, by these Articles of Incorporation or by any Preferred Stock
Designation, the provisions set forth in Article III or this Article V may not
be amended, altered or repealed in any respect, and no provision may be added to
these Articles of Incorporation limiting the effect of Article III or this
Article V, unless such action is approved by the affirmative vote of the holders
of at least 66 and  2/3% of the outstanding Voting Stock, excluding from the
number of shares deemed to be outstanding and from such vote on such amendment,
alteration or repeal all shares owned beneficially by any Interested
Shareholder; provided, however, that such special voting requirements shall not
apply to, and such special votes shall not be required for, any amendment,
alteration or repeal recommended by the Board of Directors if two-thirds ( 2/3)
of the directors then in office are Disinterested Directors.

     IN WITNESS WHEREOF, the undersigned execute these Amended and Restated
Articles of Incorporation.

                                            President

     Section 2.4 NOTICE OF MEETINGS.  Unless waived as contemplated in Section
5.2, a notice of each meeting of shareholders stating the date, time and place
of the meeting shall be given not less than ten (10) days nor more than sixty
(60) days before the date thereof, by or at the direction of the President, the
Secretary, or the officer or persons calling the meeting, to each shareholder
entitled to vote at that meeting. In the case of an annual meeting, the notice
need not state the purpose or purposes of the meeting unless the articles of
incorporation or the Georgia Business Corporation Code (the "Corporation Code")
requires the purpose or purposes to be stated in the notice of the meeting. In
the case of a special meeting, including a special meeting in lieu of an annual
meeting, the notice of meeting shall state the purpose or purposes for which the
meeting is called.

     Section 2.5 VOTING GROUP.  Voting group means all shares of one or more
classes or series that are entitled to vote and be counted together collectively
on a matter at a

                                       E-1
<PAGE>   184

meeting of shareholders. All shares entitled to vote generally on the matter are
for that purpose a single voting group.

     Section 2.6 QUORUM.  With respect to shares entitled to vote as a separate
voting group on a matter at a meeting of shareholders, the presence, in person
or by proxy, of a majority of the votes entitled to be cast on the matter by the
voting group shall constitute a quorum of that voting group for action on that
matter unless the articles of incorporation or the Corporation Code provides
otherwise. Once a share is represented for any purpose at a meeting, other than
solely to object to holding the meeting or to transacting business at the
meeting, it is deemed present for quorum purposes for the remainder of the
meeting and for any adjournment of the meeting unless a new record date is or
must be set for the adjourned meeting pursuant to Section 8.7 of these bylaws.

     Section 2.7 VOTE REQUIRED FOR ACTION.  If a quorum exists, action on a
matter (other than the election of directors) by a voting group is approved if
the votes cast within the voting group favoring the action exceed the votes cast
opposing the action, unless the articles of incorporation, provisions of these
bylaws validly adopted by the shareholders, or the Corporation Code requires a
greater number of affirmative votes. If the articles of incorporation or the
Corporation Code provide for voting by two or more voting groups on a matter,
action on that matter is taken only when voted upon by each of those voting
groups counted separately. Action may be taken by one voting group on a matter
even though no action is taken by another voting group entitled to vote on the
matter. With regard to the election of directors, unless otherwise provided in
the articles of incorporation, if a quorum exists, action on the election of
directors is taken by a plurality of the votes cast by the shares entitled to
vote in the election.

     Section 2.8 VOTING OF SHARES.  Unless the articles of incorporation or the
Corporation Code provides otherwise, each outstanding share having voting rights
shall be entitled to one vote on each matter submitted to a vote at a meeting of
shareholders. Voting on all matters shall be by voice vote or by show of hands
unless any qualified voter, prior to the voting on any matter, demands vote by
ballot, in which case each ballot shall state the name of the shareholder voting
and the number of shares voted by him, and if the ballot be cast by proxy, it
shall also state the name of the proxy.

     Section 2.9 PROPER BUSINESS AT ANNUAL MEETINGS.  At any annual meeting of
the shareholders, only such business shall be conducted as shall have been
properly brought before such meeting. To be properly brought before an annual
meeting, business must be specified in the notice of meeting (or any supplement
thereto) given by or at the direction of the Board of Directors, or otherwise
properly brought before the meeting by or at the direction of the Board of
Directors, or otherwise properly brought before the meeting by a shareholder.
For business to be properly brought before an annual meeting by a shareholder,
the shareholder must have given timely notice thereof in writing to the
Secretary of the Corporation. To be timely, a shareholder's notice must be
delivered to, or mailed and received at, the principal executive offices of the
Corporation not less than 45 days prior to the month and day of that year
corresponding to the month and day of the previous year on which the annual
meeting of shareholders was held (or at least 45 days prior to the date of the
annual meeting for that year if the date of such meeting has been publicly
announced by the Corporation at least 60 days in advance of such meeting date).
A shareholder's notice to the Secretary shall set forth as to each matter the
shareholder proposes to bring before the annual meeting (i) a brief description
of the business desired to be brought before the annual meeting and the reasons
for conducting such business at the annual meeting, (ii) the name and record
address of the shareholder proposing such

                                       E-2
<PAGE>   185

business, (iii) the class and number of shares of the Corporation which are
beneficially owned by the shareholder and (iv) any material interest of the
shareholder in such business. The chairman of an annual meeting shall, if the
facts warrant, determine and declare to the meeting that such business was not
properly brought before the meeting in accordance with these provisions, and if
he should so determine, he shall so declare to the meeting and any such business
not properly brought before the meeting shall not be transacted.

     Section 2.10 PROXIES.  A shareholder entitled to vote pursuant to Section
2.8 may vote in person or by proxy pursuant to an appointment of proxy executed
in writing by the shareholder or by his attorney in fact. An appointment of
proxy shall be valid for only one meeting to be specified therein, and any
adjournments of such meeting, but shall not be valid for more than eleven months
unless expressly provided therein. Appointments of proxy shall be dated and
filed with the records of the meeting to which they relate. If the validity of
any appointment of proxy is questioned, it must be submitted to the secretary of
the meeting of shareholders for examination or to a proxy officer or committee
appointed by the person presiding at the meeting. The secretary of the meeting
or, if appointed, the proxy officer or committee, shall determine the validity
or invalidity of any appointment of proxy submitted and reference by the
secretary in the minutes of the meeting to the regularity of an appointment of
proxy shall be received as prima facie evidence of the facts stated for the
purpose of establishing the presence of a quorum at the meeting and for all
other purposes.

     Section 2.11 PRESIDING OFFICER.  The Chairman shall serve as the chairman
of every meeting of shareholders unless another person is elected by
shareholders to serve as chairman at the meeting. The chairman shall appoint any
persons he deems required to assist with the meeting.

     Section 2.12 ADJOURNMENTS.  Whether or not a quorum is present to organize
a meeting, any meeting of shareholders (including an adjourned meeting) may be
adjourned by the holders of a majority of the voting shares represented at the
meeting to reconvene at a specific time and place, but no later than 120 days
after the date fixed for the original meeting unless the requirements of the
Corporation Code concerning the selection of a new record date have been met. At
any reconvened meeting within that time period, any business may be transacted
that could have been transacted at the meeting that was adjourned. If notice of
the adjourned meeting was properly given, it shall not be necessary to give any
notice of the reconvened meeting or of the business to be transacted, if the
date, time and place of the reconvened meeting are announced at the meeting that
was adjourned and before adjournment; provided, however, that if a new record
date is or must be fixed, notice of the reconvened meeting must be given to
persons who are shareholders as of the new record date.

     Section 2.13 ACTION OF SHAREHOLDERS WITHOUT A MEETING.  As provided in the
articles of incorporation, no action shall be taken by shareholders of the
Corporation except at an annual or special meeting of shareholders of the
Corporation and the right of shareholders to act by written consent in lieu of a
meeting is specifically denied.

                             THE BOARD OF DIRECTORS

     Section 3.1 GENERAL POWERS.  All corporate powers shall be exercised by or
under the authority of, and the business and affairs of the Corporation shall be
managed by or under the direction of, the Board of Directors. In addition to the
powers and authority expressly conferred upon it by these bylaws, the Board of
Directors may exercise all powers of the Corporation and do all lawful acts and
things that are not prohibited by law, by any legal agreement among
shareholders, by the articles of incorporation or by these bylaws directed or
required to be exercised or done by the shareholders.

     Section 3.2 NUMBER, ELECTION, CLASSIFICATION AND TERM OF OFFICE.  As
provided in the articles of incorporation, the Board of Directors shall consist
of not less than three nor more than twenty-one directors. The exact number of
directors shall be determined from time to time by resolution adopted by the
affirmative vote of a majority of the Board of Directors. The directors shall be
divided into three classes, designated Class I, Class II and Class III. Each
class shall consist, as nearly as may be possible, of one-third of the total
number of directors constituting the entire Board of Directors. The initial
directors designated in the articles of incorporation as members of Class I
shall hold office until the annual meeting of shareholders to be held in 1998,
the initial directors designated in the articles of incorporation as members of
Class II shall hold office until the annual meeting of shareholders to be held
in 1999, and the initial directors designated in the articles of incorporation
as members of Class III shall hold office until the annual meeting of
shareholders to be held in 2000. At each annual meeting of shareholders,
successors to the class of directors whose term expires at that annual meeting
shall be elected for a three-year term. Directors shall serve until the
expiration of their terms and until their successors have been elected and
qualify, subject to the director's prior death, resignation, disqualification or
removal from office.

     Section 3.3 NOMINATION PROCEDURES.  Only persons who are nominated in
accordance with the following procedures shall be eligible for election as
Directors. Nominations of persons for election to the Board of Directors of the
Corporation may be made at a meeting of shareholders by or at the direction of
the Board of Directors, by any nominating committee or person appointed by the
Board of Directors or by any shareholder of the Corporation entitled to vote for
the election of Directors at the meeting. Such nominations, other than those
made by or at the direction of the Board of Directors, shall be made pursuant to
timely notice in writing to the Secretary of the Corporation. To be timely, a
shareholder's notice shall be delivered to, or mailed and received at, the
principal executive offices of the Corporation not less than 45 days prior to
the month and day of that year corresponding to the month and day of the
previous year on which the annual meeting of shareholders was held (or at least
45 days prior to the date of the annual meeting for that year if the date of
such meeting has been publicly announced by the Corporation at least 60 days in
advance of such meeting date). Such shareholder's notice shall set forth (a) as
to each person whom the shareholder proposes to nominate for election or
re-election as director, (i) the name, age, business address and residence
address of the person, (ii) the principal occupation or employment of the
person, (iii) the class and number of shares of the Corporation which are
beneficially owned by the person and (iv) any other information relating to the
person that is required to be disclosed in solicitations of proxies for election
of Directors pursuant to Section 14(a) under the Securities Exchange Act of
1934, as amended (the "Act"), and any other applicable laws or rules or
regulations of any governmental authority or of any national securities exchange

                                       E-4
<PAGE>   187

or similar body overseeing any trading market on which shares of the corporation
are traded, and (b) as to the shareholder giving the notice (i) the name and
record address of shareholder and (ii) the class and number of shares of the
Corporation which are beneficially owned by the shareholder. No person shall be
eligible for election as a Director of the Corporation unless nominated in
accordance with the procedures set forth herein. The chairman of the meeting
shall, if the facts warrant, determine and declare to the meeting that a
nomination was not made in accordance with the foregoing procedure, and if he
should so determine, he shall so declare to the meeting and the defective
nomination shall be disregarded.

     Section 3.4 REMOVAL.  As provided in the articles of incorporation, the
shareholders shall not have the right to remove any one or all of the directors
except for cause and by the affirmative vote of the holders of at least 66 and
2/3% of the outstanding shares of the Voting Stock that are not beneficially
owned (as defined in the articles of incorporation) by any Interested
Shareholder (as defined in the articles of incorporation).

     Section 3.5 VACANCIES.  As provided in the articles of incorporation, if
the number of directors is changed in accordance with the terms of the articles
of incorporation, any increase or decrease shall be apportioned among the
classes so as to maintain the number of directors in each class as nearly equal
as possible. Any vacancy on the Board of Directors that results from a newly
created directorship, and any other vacancy occurring on the Board of Directors,
shall be filled by the affirmative vote of a majority of the Board of Directors
then in office, although less than a quorum, or by a sole remaining director. A
director of any class elected by the Board of Directors to fill a vacancy shall
hold office until the next annual meeting of shareholders. A director of any
class elected by the shareholders to fill a vacancy shall hold office for a term
that shall coincide with the remaining term of that class. In no case will a
decrease in the number of directors shorten the term of any incumbent director.
The election of directors need not be by written ballot unless the Corporation's
Bylaws so require.

     Section 3.6 COMPENSATION.  Unless the articles of incorporation provide
otherwise, the Board of Directors may determine from time to time the
compensation, if any, directors may receive for their services as directors. A
director may also serve the Corporation in a capacity other than that of
director and receive compensation, as determined by the Board of Directors, for
services rendered in any other capacity.

The right of dissent or abstention is not available to a director who votes in
favor of the action taken.

     Section 4.7 PARTICIPATION BY CONFERENCE TELEPHONE.  Any or all directors
may participate in a meeting of the Board of Directors or of a committee of the
Board of Directors through the use of any means of communication by which all
directors participating may simultaneously hear each other during the meeting.

incorporation or these bylaws provide otherwise, any action required or
permitted to be taken at any meeting of the Board of Directors or any action
that may be taken at a meeting of a committee of the Board of Directors may be
taken without a meeting if the action is taken by all the members of the Board
of Directors (or of the committee as the case may be). The action must be
evidenced by one or more written consents describing the action taken, signed by
each director (or each director serving on the committee, as the case may be),
and delivered to the Corporation for inclusion in the minutes or filing with the
corporate records.

     Section 4.9 ADJOURNMENTS.  Whether or not a quorum is present to organize a
meeting, any meeting of directors (including an adjourned meeting) may be

meeting are announced at the meeting that was adjourned.

     Section 4.10 COMMITTEES OF THE BOARD OF DIRECTORS.  The Board of Directors
by resolution may designate from among its members an executive committee and

          (c) the Corporation either has no duty to inquire into adverse claims
     or has discharged that duty; and

          (d) the requirements of any applicable law relating to the collection
     of taxes have been met; and

          (e) the transfer in fact is rightful or is to a bona fide purchaser.

     Section 8.6 LOST, STOLEN OR DESTROYED CERTIFICATES.  Any person claiming a
share certificate to be lost, stolen or destroyed shall make an affidavit or
affirmation of the fact in the manner required by the Board of Directors and, if
the Board of Directors requires, shall give the Corporation a bond of indemnity
in form and amount, and with one or more sureties satisfactory to the Board of
Directors, as the Board of Directors may require, whereupon an appropriate new
certificate may be issued in lieu of the one alleged to have been lost, stolen
or destroyed.

     Section 8.7 FIXING OF RECORD DATE WITH REGARD TO SHAREHOLDER ACTION.  For
the purpose of determining shareholders entitled to notice of a shareholders'
meeting, to demand a special meeting, to vote, or to take any other action, the
Board of Directors may

                                      E-10
<PAGE>   193

fix a future date as the record date, which date shall be not more than seventy
(70) days prior to the date on which the particular action, requiring a
determination of shareholders, is to be taken. A determination of shareholders
entitled to notice of or to vote at a shareholders' meeting is effective for any
adjournment of the meeting unless the Board of Directors fixes a new record
date, which it must do if the meeting is adjourned to a date more than 120 days
after the date fixed for the original meeting. If no record date is fixed by the
Board of Directors, the record date shall be determined in accordance with the
provisions of the Corporation Code.

                                  ARTICLE NINE

                                INDEMNIFICATION

     Section 9.1 CERTAIN DEFINITIONS.  As used in this Article, the term:

          (a) "Corporation" includes any domestic or foreign predecessor entity
     of this Corporation in a merger or other transaction in which the
     predecessor's existence ceased upon consummation of the transaction.

          (b) "Director" means an individual who is or was a director of the
     Corporation or an individual who, while a director of the Corporation, is
     or was serving at the Corporation's request as a director, officer,
     partner, trustee, employee, or agent of another foreign or domestic
     corporation, partnership, joint venture, trust, employee benefit plan, or
     other enterprise. Directors of the Corporation who are serving as
     directors, officers, employees or agents of any subsidiary of the
     Corporation shall be considered to be serving at the Corporation's request
     and shall be considered a "director" for the purposes of this Article. A
     director is considered to be serving an employee benefit plan at the
     Corporation's request if his duties to the Corporation also impose duties
     on, or otherwise involve services by, him to the plan or to participants in
     or beneficiaries of the plan. "Director" includes, unless the context
     requires otherwise, the estate or personal representative of a director.

          (c) "Expenses" includes attorneys' fees.

          (d) "Liability" means the obligation to pay a judgment, settlement,
     penalty, fine (including an excise tax assessed with respect to an employee
     benefit plan), or reasonable expenses incurred with respect to a
     proceeding.

          (e) "Officer" means an individual who is or was an officer of the
     Corporation or an individual who, while an officer of the Corporation, is
     or was serving at the Corporation's request as a director, officer,
     partner, trustee, employee, or agent of another foreign or domestic
     corporation, partnership, joint venture, trust, employee benefit plan, or
     other enterprise. Officers of the Corporation who are serving as directors,
     officers, employees or agents of any subsidiary of the Corporation shall be
     considered to be serving at the Corporation's request and shall be
     considered an "officer" for the purposes of this Article. An officer is
     considered to be serving an employee benefit plan at the Corporation's
     request if his duties to the Corporation also impose duties on, or
     otherwise involve services by, him to the plan or to participants in or
     beneficiaries of the plan. "Officer" includes, unless the context requires
     otherwise, the estate or personal representative of an officer.

                                      E-11
<PAGE>   194

          (f) "Party" includes an individual who was, is, or is threatened to be
     made a named defendant or respondent in a proceeding.

          (g) "Proceeding" means any threatened, pending, or completed action,
     suit, or proceeding, whether civil, criminal, administrative, or
     investigative and whether formal or informal.

          (h) "Reviewing Party" shall mean the person or persons making the
     entitlement determination pursuant to Section 9.4 of this Article, and
     shall not include a court making any determination under this Article or
     otherwise.

     Section 9.2 BASIC INDEMNIFICATION ARRANGEMENT.

     (a) To the extent that a director or officer has been successful, on the
merits or otherwise, in the defense of any proceeding to which he was a party,
or in defense of any claim, issue, or matter therein, because he is or was a
director or officer, the Corporation shall indemnify the director or officer
against reasonable expenses incurred in connection therewith. Except as provided
in subsections 9.2(d) and 9.2(e) below, the Corporation shall in addition
indemnify an individual who is made a party to a proceeding because he is or was
a director or officer against liability incurred by him in the proceeding if he
acted in a manner he believed in good faith to be in or not opposed to the best
interests of the Corporation and, in the case of any criminal proceeding, he had
no reasonable cause to believe his conduct was unlawful.

     (b) A person's conduct with respect to an employee benefit plan for a
purpose he believed in good faith to be in the interests of the participants in
and beneficiaries of the plan is conduct that satisfies the requirement of
subsection 9.2(a).

     (c) The termination of a proceeding by judgment, order, settlement, or
conviction, or upon a plea of nolo contendere or its equivalent shall not, of
itself, be determinative that the proposed indemnified person did not meet the
standard of conduct set forth in subsection 9.2(a).

     (d) The Corporation shall not indemnify a person under this Article in
connection with (i) a proceeding by or in the right of the Corporation in which
such person was adjudged liable to the Corporation, or (ii) any proceeding in
which such person was adjudged liable on the basis that he improperly received a
personal benefit; unless in either case, and then only to the extent that, a
court of competent jurisdiction acting pursuant to Section 9.5 of this Article
or Section 14-2-854 of the Georgia Business Corporation Code, determines that,
in view of the circumstances of the case, such person is fairly and reasonably
entitled to indemnification.

     (e) Indemnification permitted under this Article in connection with a
proceeding by or in the right of the Corporation is limited to reasonable
expenses incurred in connection with the proceeding.

<PAGE>   195

     Section 9.3 ADVANCES FOR EXPENSES.

     (a) The Corporation shall pay for or reimburse the reasonable expenses
incurred by a director or officer as a party to a proceeding in advance of final
disposition of the proceeding if:

          (i) Such person furnishes the Corporation a written affirmation of his
     good faith belief that he has met the standard of conduct set forth in
     subsection 9.2(a) above; and

          (ii) Such person furnishes the Corporation a written undertaking
     (meeting the qualifications set forth below in subsection 9.3(b)), executed
     personally or on his behalf, to repay any advances if it is ultimately
     determined that he is not entitled to indemnification under this Article or
     otherwise.

     (b) The undertaking required by subsection 9.3(a)(ii) above must be an
unlimited general obligation of the proposed indemnified person but need not be
secured and shall be accepted without reference to financial ability to make
repayment.

     Section 9.4 AUTHORIZATION OF AND DETERMINATION OF ENTITLEMENT TO
INDEMNIFICATION.

     (a) The Corporation acknowledges that indemnification of a director or
officer under Section 9.2 has been pre-authorized by the Corporation in the
manner described in subsection 9.4(b) below. Nevertheless, the Corporation shall
not indemnify a director or officer under Section 9.2 unless a separate
determination has been made in the specific case that indemnification of such
person is permissible in the circumstances because he has met the standard of
conduct set forth in subsection 9.2(a); provided, however, that regardless of
the result or absence of any such determination, and unless limited by the
articles of incorporation of the Corporation, to the extent that a director or
officer has been successful, on the merits or otherwise, in the defense of any
proceeding to which he was a party, or in defense of any claim, issue or matter
therein, because he is or was a director or officer, the Corporation shall
indemnify such person against reasonable expenses incurred by him in connection
therewith.

     (b) The determination referred to in subsection 9.4(a) above shall be made,
at the election of the board of directors:

          (i) by the board of directors of the Corporation by majority vote of a
     quorum consisting of directors not at the time parties to the proceeding;

          (ii) if a quorum cannot be obtained under subdivision (i), by majority
     vote of a committee duly designated by the board of directors (in which
     designation directors who are parties may participate), consisting solely
     of two or more directors not at the time parties to the proceeding;

          (iii) by special legal counsel:

             (1) selected by the board of directors or its committee in the
        manner prescribed in subdivision (i) or (ii); or

             (2) if a quorum of the board of directors cannot be obtained under
        subdivision (i) and a committee cannot be designated under subdivision
        (ii), selected by a majority vote of the full board of directors (in
        which selection directors who are parties may participate); or

                                      E-13
<PAGE>   196

          (iv) by the shareholders; provided that shares owned by or voted under
     the control of directors or officers who are at the time parties to the
     proceeding may not be voted on the determination.

     (c) As acknowledged above, the Corporation has pre-authorized the
indemnification of directors and officers hereunder, subject to a case-by-case
determination that the proposed indemnified person met the applicable standard
of conduct under subsection 9.2(a). Consequently, no further decision need or
shall be made on a case-by-case basis as to the authorization of the
Corporation's indemnification of directors and officers hereunder. Nevertheless,
evaluation as to reasonableness of expenses of a director or officer in the
specific case shall be made in the same manner as the determination that
indemnification is permissible, as described in subsection 9.4(b) above, except
that if the determination is made by special legal counsel, evaluation as to
reasonableness of expenses shall be made by those entitled under subsection
9.4(b)(iii) to select counsel.

     (d) The Reviewing Party acting pursuant to subsections 9.4(b) or 9.4(c)
above shall act expeditiously and reasonably upon an application for
indemnification or advancement of expenses, and shall cooperate in the
procedural steps required to obtain court-ordered indemnification or advancement
of expenses under Section 9.5 below.

     Section 9.5 COURT-ORDERED INDEMNIFICATION AND ADVANCES FOR
EXPENSES.  Unless this Corporation's articles of incorporation provide
otherwise, a director or officer who is a party to a proceeding may apply for
indemnification or advances for expenses to the court conducting the proceeding
or to another court of competent jurisdiction. For purposes of this Article, the
Corporation hereby consents to personal jurisdiction and venue in any court in
which is pending a proceeding to which a director or officer is a party.
Regardless of any determination by the Reviewing Party that the proposed
indemnified person is not entitled to indemnification or advancement of expenses
or as to the reasonableness of expenses, and regardless of any failure by the
Reviewing Party to make a determination as to such entitlement or the
reasonableness of expenses, such court's review shall be a de novo review, and
its determination shall be binding, on the questions of whether:

          (a) The applicant is entitled to mandatory indemnification under the
     final clause of subsection 9.4(a) above (in which case the Corporation
     shall pay the indemnified person's reasonable expenses incurred to obtain
     court-ordered indemnification);

          (b) The applicant is fairly and reasonably entitled to indemnification
     in view of all the relevant circumstances, whether or not he met the
     standard of conduct set forth in subsection 9.2(a) above or was adjudged
     liable as described in subsection 9.2(d) above (but if he was adjudged so
     liable, any court-ordered indemnification shall be limited to reasonable
     expenses incurred by the indemnified person, including reasonable expenses
     incurred to obtain court-ordered indemnification, unless the articles of
     incorporation of this Corporation or a bylaw, contract or resolution
     approved or ratified by the shareholders pursuant to Section 9.7 provides
     otherwise); or

          (c) In the case of advances for expenses, the applicant is entitled
     pursuant to the articles of incorporation, bylaws or applicable resolution
     or agreement to payment for or reimbursement of his reasonable expenses
     incurred as a party to a proceeding in advance of final disposition of the
     proceeding (in which case the Corporation shall pay the applicant's
     reasonable expenses incurred to obtain court-ordered advancement of
     expenses).

                                      E-14
<PAGE>   197

     In any claim brought by the proposed indemnified person seeking
court-ordered indemnification or advancement of expenses, the failure of the
Reviewing Party to act in accordance with Section 9.4(d) may properly be
considered by the court in assessing the expenses of the proposed indemnified
person.

     Section 9.6 INDEMNIFICATION OF EMPLOYEES AND AGENTS.  Unless this
Corporation's articles of incorporation provide otherwise, the Corporation may
indemnify and advance expenses under this Article to an employee or agent of the
Corporation or any subsidiary of the Corporation who is not a director or
officer to the same extent as to a director or officer, or to any lesser extent
(or greater extent if permitted by law), determined by the board of directors.

     Section 9.7 SHAREHOLDER APPROVED INDEMNIFICATION.

     (a) If authorized by the articles of incorporation or a bylaw, contract or
resolution approved or ratified by the shareholders of the Corporation by a
majority of the votes entitled to be cast, the Corporation may indemnify or
obligate itself to indemnify a person made a party to a proceeding, including a
proceeding brought by or in the right of the Corporation, without regard to the
limitations in other sections of this Article. The Corporation shall not
indemnify a person under this Section 9.7 for any liability incurred in a
proceeding in which the person is adjudged liable to the Corporation or is
subjected to injunctive relief in favor of the Corporation:

          (i) for any appropriation, in violation of his duties, of any business
     opportunity of the Corporation;

          (ii) for acts or omissions which involve intentional misconduct or a
     knowing violation of law;

          (iii) for the types of liability set forth in Section 14-2-832 of the
     Georgia Business Corporation Code; or

          (iv) for any transaction from which he received an improper personal
     benefit.

     (b) Where approved or authorized in the manner described in subsection
9.7(a) above, the Corporation may advance or reimburse expenses incurred in
advance of final disposition of the proceeding only if:

          (i) the proposed indemnified person furnishes the Corporation a
     written affirmation of his good faith belief that his conduct does not
     constitute behavior of the kind described in subsection 9.7(a)(i)-(iv)
     above; and

          (ii) the proposed indemnified person furnishes the Corporation a
     written undertaking, executed personally, or on his behalf, to repay any
     advances if it is ultimately determined that he is not entitled to
     indemnification.

     Section 9.8 LIABILITY INSURANCE.  The Corporation may purchase and maintain
insurance on behalf of a director or officer or an individual who is or was an
employee or agent of the Corporation or who, while an employee or agent of the
Corporation, is or was serving at the request of the Corporation as a director,
officer, partner, trustee, employee or agent of another foreign or domestic
corporation, partnership, joint venture, trust, employee benefit plan, or other
enterprise against liability asserted against or incurred by him in that
capacity or arising from his status as a director, officer, employee, or agent,
whether or not

                                      E-15
<PAGE>   198

the Corporation would have power to indemnify him against the same liability
under Section 9.2, Section 9.3 or Section 9.4 above.

     Section 9.9 WITNESS FEES.  Nothing in this Article shall limit the
Corporation's power to pay or reimburse expenses incurred by a person in
connection with his appearance as a witness in a proceeding at a time when he
has not been made a named defendant or respondent in the proceeding.

     Section 9.10 REPORT TO SHAREHOLDERS.  If the Corporation indemnifies or
advances expenses to a director in connection with a proceeding by or in the
right of the Corporation, the Corporation shall report the indemnification or
advance, in writing, to the shareholders with or before the notice of the next
shareholders' meeting.

     Section 9.11 SECURITY FOR INDEMNIFICATION OBLIGATIONS.  The Corporation may
at any time and in any manner, at the discretion of the board of directors,
secure the Corporation's obligations to indemnify or advance expenses to a
person pursuant to this Article.

     Section 9.12 NO DUPLICATION OF PAYMENTS.  The Corporation shall not be
liable under this Article to make any payment to a person hereunder to the
extent such person has otherwise actually received payment (under any insurance
policy, agreement or otherwise) of the amounts otherwise payable hereunder.

     Section 9.13 SUBROGATION.  In the event of payment under this Article, the
Corporation shall be subrogated to the extent of such payment to all of the
rights of recovery of the indemnified person, who shall execute all papers
required and shall do everything that may be necessary to secure such rights,
including the execution of such documents necessary to enable the Corporation
effectively to bring suit to enforce such rights.

     Section 9.14 CONTRACT RIGHTS.  The right to indemnification and advancement
of expenses conferred hereunder to directors and officers shall be a contract
right and shall not be affected adversely to any director or officer by any
amendment of these bylaws with respect to any action or inaction occurring prior
to such amendment; provided, however, that this provision shall not confer upon
any indemnified person or potential indemnified person (in his capacity as such)
the right to consent or object to any subsequent amendment of these bylaws.

     Section 9.15 NON-EXCLUSIVITY, ETC.  The rights of a director or officer
hereunder shall be in addition to any other rights with respect to
indemnification, advancement of expenses or otherwise that he may have under
contract or the Georgia Business Corporation Code or otherwise.

     Section 9.16 SEVERABILITY.  To the extent that the provisions of this
Article are held to be inconsistent with the provisions of Part 5 of Article 8
of the Georgia Business Corporation Code, such provisions of such Code shall
govern. In the event that any of the provisions of this Article (including any
provision within a single section, subsection, division or sentence) is held by
a court of competent jurisdiction to be invalid, void or otherwise
unenforceable, the remaining provisions of this Article shall remain enforceable
to the fullest extent permitted bylaw.

     Each Buyer represents and warrants with respect to only itself that:

          a. INVESTMENT PURPOSE.  Such Buyer is acquiring the Common Stock and
     Warrants and any shares of Common Stock issuable upon exercise thereof
     ("WARRANT SHARES"), for its own account for investment only and not with a
     view towards, or for resale in connection with, the public sale or
     distribution thereof, except pursuant to sales registered or exempted under
     the 1933 Act; provided, however, that by making the representations herein,
     such Buyer does not agree to hold any Common Stock, Conversion Shares (as
     defined in Section 8 hereof), Warrants, or Warrant Shares for any minimum
     or other specific term and reserves the right to dispose of Common Stock or
     Warrant Shares at any time in accordance with or pursuant to a registration
     statement or an exemption under the 1933 Act. Notwithstanding anything
     contained herein to the contrary, each Buyer agrees to enter into any
     contractual lock-up agreements with respect to the Common Stock, Warrants,
     Warrant Shares, or Conversion Shares that may be required by the Company's
     underwriters in connection with an underwritten public offering of the
     Company's common stock or other securities or any public offering of the
     Conversion Shares or other securities of BSTI.

          b. ACCREDITED INVESTOR STATUS.  Such Buyer is an "accredited investor"
     as that term is defined in Rule 501(a)(3) of Regulation D.

          c. RELIANCE ON EXEMPTIONS.  Such Buyer understands that the Common
     Stock, Conversion Shares, Warrants, and Warrant Shares are being offered
     and sold to it in reliance on specific exemptions from the registration
     requirements of United States federal and state securities laws and that
     the Company is relying in part upon the truth and accuracy of, and such
     Buyer's compliance with, the representations, warranties, agreements,
     acknowledgments and understandings of such Buyer set forth herein in order
     to determine the availability of such exemptions and the eligibility of
     such Buyer to acquire such securities.

          d. INFORMATION.  Such Buyer and its advisors, if any, have been
     furnished with all materials relating to the business, finances and
     operations of the Company and BSTI and materials relating to the offer and
     sale of the Common Stock which have been requested by such Buyer. Such
     Buyer and its advisors, if any, have been afforded

     the opportunity to ask questions of the Company and BSTI. Neither such
     inquiries nor any other due diligence investigations conducted by such
     Buyer or its advisors, if any, or its representatives shall modify, amend
     or affect such Buyer's right to rely on the Company's or BSTI's
     representations and warranties contained in Section 3 below. Such Buyer
     understands that its investment in the Common Stock, Conversion Shares,
     Warrants, and Warrant Shares involve a high degree of risk. Such Buyer has
     sought such accounting, legal and tax advice as it has considered necessary
     to make an informed investment decision with respect to its acquisition of
     the Common Stock, Conversion Shares, Warrants, and Warrant Shares.

          e. NO GOVERNMENTAL REVIEW.  Such Buyer understands that no United
     States federal or state agency or any other government or governmental
     agency has passed on or made any recommendation or endorsement of the
     Common Stock, Conversion Shares, Warrants, and Warrant Shares, or the
     fairness or suitability of the investment in the Common Stock, nor have
     such authorities passed upon or endorsed the merits of the offering of the
     Common Stock and Warrants.

          f. TRANSFER OR RESALE.  Such Buyer understands that: (i) the Common
     Stock and Warrants have not been and are not being registered under the
     1933 Act or any state securities laws, and may not be offered for sale,
     sold, assigned or transferred unless (a) subsequently registered
     thereunder, (b) such Buyer shall have delivered to the Company an opinion
     of counsel, in a generally acceptable form, to the effect that such
     securities to be sold, assigned or transferred may be sold, assigned or
     transferred pursuant to an exemption from such registration, or (c) such
     Buyer provides the Company with reasonable assurance that such securities
     can be sold, assigned or transferred pursuant to Rule 144 promulgated under
     the 1933 Act (or a successor rule thereto) ("RULE 144"); (ii) any sale of
     such securities made in reliance on Rule 144 promulgated under the 1933 Act
     (or a successor rule thereto) may be made only in accordance with the terms
     of Rule 144 and further, if Rule 144 is not applicable, any resale of such
     securities under circumstances in which the seller (or the person through
     whom the sale is made) may be deemed to be an underwriter (as that term is
     defined in the 1933 Act) may require compliance with some other exemption
     under the 1933 Act or the rules and regulations of the SEC thereunder; and
     (iii) other than the Company Registration Rights Agreement and the BSTI
     Registration Rights Agreement (collectively, the "REGISTRATION RIGHTS
     AGREEMENTS"), neither the Company nor any other person is under any
     obligation to register such securities under the 1933 Act or any state
     securities laws or to comply with the terms and conditions of any exemption
     thereunder.

          g. LEGENDS.  Such Buyer understands that the certificates or other
     instruments representing the Common Stock, Conversion Shares, Warrants, and
     Warrant Shares shall bear a restrictive legend in substantially the
     following form (and a stop transfer order may be placed against transfer of
     such stock certificates):

        THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
        UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE
        SECURITIES LAWS. THE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND
        MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED IN THE
        ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER

        NOT REQUIRED UNDER SAID ACT OR APPLICABLE STATE SECURITIES LAWS OR
        UNLESS SOLD PURSUANT TO RULE 144 UNDER SAID ACT.

     The legend set forth above shall be removed and the Company shall issue a
certificate without such legend to the holder of the Common Stock, Conversion
Shares, Warrants and Warrant Shares upon which it is stamped, if, unless
otherwise required by state securities laws, (i) the sale of the Common Stock,
Conversion Shares, or Warrant Shares is registered under the 1933 Act, (ii) in
connection with a sale transaction, such holder provides the Company with an
opinion of counsel, in a generally acceptable form, to the effect that a public
sale, assignment or transfer of the Common Stock, Conversion Shares, Warrants,
or Warrant Shares may be made without registration under the 1933 Act, or (iii)
such holder provides the Company with reasonable assurances that the Common
Stock, Conversion Shares, Warrants, or Warrant Shares can be sold pursuant to
Rule 144 without any restriction as to the number of securities acquired as of a
particular date that can then be immediately sold.

          h. AUTHORIZATION, ENFORCEMENT.  This Agreement has been duly and
     validly authorized, executed and delivered on behalf of such Buyer and is a
     valid and binding agreement of such Buyer enforceable in accordance with
     its terms, subject as enforceability to general principles of equity and to

     provisions reasonably adequate for the payment of all unpaid and unreported
     taxes) and has paid all taxes and other governmental assessments and
     charges that are material in amount, shown or determined to be due on such
     returns, reports and declarations, except those being contested in good
     faith and has set aside on its books provision reasonably adequate for the
     payment of all taxes for periods subsequent to the periods to which such
     returns, reports or declarations apply. There are no unpaid taxes in any
     material amount claimed to be

                                       F-8
<PAGE>   208

     Company and BSTI know of no basis for any such claim.

          r. CERTAIN TRANSACTIONS.  Except as set forth on Schedule 3(v) and in
     BSTI's SEC Documents and except for arm's length transactions pursuant to
     which the Company and BSTI make payments in the ordinary course of business

     third parties and other than the grant of stock options disclosed on
     Schedule 3(c), none of the officers, directors, or employees of the Company
     or BSTI is presently a party to any transaction with the Company (other

     such employee or, to the knowledge of the Company or BSTI, any corporation,
     partnership, trust or other entity in which any officer, director, or any
     such employee has a substantial interest or is an officer, director,
     trustee or partner.

          s. DILUTIVE EFFECT.  BSTI understands and acknowledges that the number
     of Conversion Shares issuable upon exchange of the Common Stock will
     increase in certain circumstances. BSTI further acknowledges that its
     obligation to issue Conversion Shares upon exchange of the Common Stock 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 BSTI.

     (as defined below); provided, however, that in no event shall any holder be
     entitled to (i) exchange Common Stock into Conversion Shares in excess of
     that number of Common Stock which, upon giving effect to such conversion,

     the holder and its affiliates to exceed 4.9% of the outstanding shares of
     the Common Stock following such conversion or (ii) exchange more than 10%
     of the total number of Conversion Shares issued to such holder into
     Conversion Shares (or any successor or assign) pursuant to this transaction
     in any thirty (30) day period commencing on the Exchange Commencement Date
     and any succeeding thirty (30) day period thereafter. For purposes of the
     foregoing proviso, the aggregate

        any such case, BSTI will make appropriate provision (in form and
        substance reasonably satisfactory to the holders of a majority of the
        Common Stock issued in connection with this transaction then
        outstanding) with respect to such holders' rights and interests to
        insure that the provisions of this Section 8(d) and Section 8(e) below
        will thereafter be applicable to the Common Stock. BSTI will not effect
        any such consolidation, merger or sale, unless prior to the consummation
        thereof the successor entity (if other than BSTI) resulting from
        consolidation or merger or the entity purchasing such assets assumes, by

        holders of a majority of the Common Stock issued in connection with this
        transaction then outstanding), the obligation to deliver to each holder
        of Common Stock issued in connection with this transaction such shares

             adjustment.

                  (B) BSTI will give written notice to each holder of Common
             Stock issued in connection with this transaction at least twenty
             (20) days prior to the date on which BSTI closes its books or takes
             a record (I) with respect to any dividend or distribution upon the

             (III) for determining rights to vote with respect to any Organic
             Change, dissolution or liquidation.

                  (C) BSTI will also give written notice to each holder of
             Common Stock issued in connection with this transaction at least
             twenty (20) days prior to the date on which any Organic Change,
             dissolution, or liquidation will take place.

          (e) MECHANICS OF EXCHANGE OF COMMON STOCK INTO CONVERSION SHARES.

             (i) Holder's Delivery Requirements. Such notice exchanging Common
        Stock into Conversion Shares in accordance with this Section 8 by the
        holder (the "EXCHANGE NOTICE") shall (A) be delivered by facsimile to
        the Company and BSTI for receipt on or prior to 12:00 noon Eastern
        Standard Time or (B) the immediately succeeding Trading Day if it is
        received by facsimile or otherwise after 12:00 noon Eastern Standard
        Time on a Trading Day (the "EXCHANGE DATE") and (B) the holder shall
        surrender to a common carrier for delivery to BSTI as soon as
        practicable following such date, but in no event later than four (4)
        Trading Days prior to a Closing Date, the original certificates
        representing the Common Stock being exchanged (or an indemnification
        undertaking with respect to such shares in the case of their loss,
        theft, or destruction) and the originally executed conversion notice.

             (ii) The Company and BSTI Response. Upon receipt by the Company and
        BSTI of a facsimile copy of the Exchange Notice, the Company and BSTI
        shall send via facsimile, a confirmation of receipt of such Exchange
        Notice to such holder. Upon receipt by the Company of the Common Stock
        Certificates to be exchanged pursuant to an Exchange Notice, together
        with the originally executed Exchange Notice, BSTI or the transfer agent
        (as applicable) shall, within three (3) business days of each Closing
        Date (A) issue and surrender to a common carrier for overnight delivery
        to the address as specified in the Exchange Notice, a certificate,
        registered in the name of the holder or its designee, for the number of
        Conversion Shares to which the holder shall be entitled. In lieu of
        delivering physical certificates representing the Conversion Shares
        issuable in accordance with this Section 8(e) and provided that the
        transfer agent then is participating in the Depository Trust Company
        ("DTC") Fast Automated Securities Transfer ("FAST") program, upon
        request of a holder, BSTI shall use its commercially reasonable efforts
        to cause the transfer agent to electronically transmit the applicable
        number of Conversion Shares by crediting the account of the holder's
        prime broker with DTC through its Deposit Withdrawal Agent Commission
        ("DWAC") system. In addition, on or prior to such Closing Date, each of
        BSTI, the Company, and the holder shall deliver to the others all
        documents, instruments, and writings required to be delivered or
        reasonably requested by any of them pursuant to this Agreement in order
        to implement and effect the transactions contemplated herein.

             (iii) RECORD HOLDER.  The person or persons entitled to receive the
        Conversion Shares issuable upon an exchange of Common Stock shall be
        treated for all purposes as the record holder or holders of such shares
        of Conversion Shares on the Exchange Date.

                                      F-17
<PAGE>   217

             (iv) BSTI'S FAILURE TO TIMELY EXCHANGE.  If BSTI shall fail to
        issue to a holder on a Closing Date, a certificate for the number of
        shares of Conversion Shares to which such holder is entitled upon such
        holder's exchange of Common Stock, in addition to all other available
        remedies which such holder may pursue hereunder (including
        indemnification pursuant to Section 7 hereof), the Company shall pay
        additional damages to such holder on each day after the fifth (5th)
        Trading Day following the applicable Closing Date for which such
        exchange is not timely effected, an amount equal to 1.0% of the product
        of number of Conversion Shares not issued to such holder to which such
        holder is entitled by the Exchange Price for each calendar month until
        such exchange is made unless Buyer elects to enforce the terms of
        Section 11 herein.

          (f) FRACTIONAL SHARES.  BSTI shall not issue any fraction of a
     Conversion Share upon any exchange. All Conversion Shares (including
     fractions thereof) issuable upon conversion of more than one share of
     Common Stock by a holder thereof shall be aggregated for purposes of
     determining whether the conversion would result in the issuance of a
     fraction of a Conversion Share. If, after the aforementioned aggregation,
     the issuance would result in the issuance of a fraction of its Conversion
     Share, BSTI shall round such fraction of a Conversion Share up or down to
     the nearest whole share.

     (9) CASH PAYMENT OPTION BY BSTI.

     In lieu of issuing the Conversion Shares in accordance with an Exchange
Notice, BSTI shall have the right, in its sole discretion, to pay to the holder
of the Common Stock an amount equal to $5.825 for each share of Common Stock so
exchanged (as adjusted for stock splits and similar events of the Company)
("CASH OUT PRICE"). The Company shall pay the Cash Out Price to that Holder
within seven (7) Trading Days following the receipt by the Company and BSTI of
an Exchange Notice.

     (10) COMPANY'S RIGHT TO REDEEM AT ITS ELECTION.

          (a) At any time, the Company shall have the right, in its sole
     discretion, to redeem ("REDEMPTION AT COMPANY'S ELECTION"), from time to
     time, any or all of the Common Stock; provided (i) the Company shall first
     provide no more than seven (7) Trading Days and no less than one (1)
     Trading Day advance written notice as provided in subparagraph 10(a)(ii)
     below, and (ii) that the Company shall only be entitled to redeem Common
     Stock having an aggregate Stated Value (as defined above) of at least Five
     Hundred Thousand Dollars ($500,000). If the Company elects to redeem some,
     but not all, of the Common Stock, the Company shall redeem a pro-rata
     amount from each Holder of the Common Stock.

             (i) REDEMPTION PRICE AT COMPANY'S ELECTION.  The "REDEMPTION PRICE
        AT COMPANY'S ELECTION" shall be calculated as $5.825 (as adjusted for
        stock splits and similar events of the Company).

             (ii) MECHANICS OF REDEMPTION AT COMPANY'S ELECTION.  The Company
        shall effect each such redemption by giving no more than seven (7)
        Trading Days and no less than one (1) Trading Day prior written notice
        ("NOTICE OF REDEMPTION AT COMPANY'S ELECTION") to (A) the Holders of the
        Common Stock selected for redemption at the address and facsimile number
        of such Holder appearing in the Company's Common Stock register and (B)
        the Transfer Agent, which Notice of Redemption At Company's Election
        shall be deemed to have been delivered

                                      F-18
<PAGE>   218

        three (3) Trading Days after the Company's mailing (by overnight or two
        (2) day courier, with a copy by facsimile) of such Notice of Redemption
        at Company's Election. Such Notice of Redemption At Company's Election
        shall indicate (i) the number of shares of Common Stock that have been
        selected for redemption, (ii) the date which such redemption is to
        become effective (the "DATE OF REDEMPTION AT COMPANY'S ELECTION"), and
        (iii) the applicable Redemption Price At Company's Election, as defined
        in subsection (a)(i) above.

          (b) Company Must Have Immediately Available Funds or Credit
     Facilities. The Company shall not be entitled to send any Redemption Notice
     and begin the redemption procedure under Sections 10(a) unless it has:

             (i) the full amount of the redemption price in cash, available in a
        demand or other immediately available account in a bank or similar
        financial institution; or

             (ii) immediately available credit facilities, in the full amount of
        the redemption price with a bank or similar financial institution, or

             (iii) an agreement with a standby underwriter willing to purchase
        from the Company a sufficient number of shares of stock to provide
        proceeds necessary to redeem any stock that is not converted prior to
        redemptions; or

             (iv) a combination of the items set forth in (i), (ii), and (iii)
        above, aggregating the full amount of the redemption price.

          (c) PAYMENT OF REDEMPTION PRICE.  Each Holder submitting Common Stock
     being redeemed under this Section 10 shall send their Common Stock
     Certificates to be redeemed to the Company or its Transfer Agent, and the
     Company shall pay the applicable redemption price to that Holder within
     five (5) business days of the Date of Redemption at Company's Election.

     (11) INABILITY TO FULLY EXCHANGE.

          (a) HOLDER'S OPTION IF BSTI CANNOT FULLY EXCHANGE.  If at any time
     after the Exchange Commencement Date, upon the Company's and BSTI's receipt
     of an Exchange Notice, BSTI does not issue shares which are registered for
     resale under the BSTI Registration Statement within five (5) business days
     of the time required for any reason or for no reason, including, without
     limitation, because BSTI (x) does not have a sufficient number of
     Conversion Shares authorized and available, (y) is otherwise prohibited by
     applicable law or by the rules or regulations of any stock exchange,
     interdealer quotation system or other self-regulatory organization with
     jurisdiction over BSTI or its securities, including without limitation The
     Nasdaq Stock Market, Inc. from issuing all of the Conversion Shares which
     is to be issued to a holder of Common Stock pursuant to an Exchange Notice
     or (z) fails to have a sufficient number of Conversion Shares registered
     and eligible for resale under the BSTI Registration Statement, then BSTI
     shall issue as many Conversion Shares as it is able to issue in accordance
     with such holder's Exchange Notice and pursuant to Section 8(e) above and,
     with respect to the unconverted Common Stock, the holder, solely at such
     holder's option, can, in addition to any other remedies such holder may

                                      F-19
<PAGE>   219

     have hereunder, under this Agreement (including indemnification under
     Section 7 thereof), under the BSTI Registration Rights Agreement, at law or
     in equity, elect to:

             (i) require BSTI to redeem from such holder those shares of
        Conversion Stock for which BSTI is unable to issue Conversion Shares in
        accordance with such holder's Exchange Notice ("MANDATORY REDEMPTION")
        at a price per share of Common Stock (the "MANDATORY REDEMPTION PRICE")
        equal to $5.825 (as adjusted for stock splits or similar events of the
        Company;

             (ii) require BSTI to issue restricted shares of Common Stock in
        accordance with such holder's Exchange Notice and pursuant to Section
        8(e) above, if BSTI's inability to fully exchange Common Stock is
        pursuant to its inability to deliver Conversion Shares registered
        pursuant to the 1933 Act; or

             (iii) void its Exchange Notice and retain or have returned, as the
        case may be, the unexchanged Common Stock that were to be exchanged
        pursuant to such holder's Exchange Notice.

          (b) MECHANICS OF FULFILLING HOLDER'S ELECTION.  BSTI shall send via
     facsimile to a holder of Common Stock, upon receipt of a facsimile copy of
     an Exchange Notice from such holder which cannot be fully satisfied as
     described in Section 11(a) above, a notice of BSTI's inability to fully
     satisfy such holder's Exchange Notice (the "INABILITY TO FULLY EXCHANGE
     NOTICE"). Such Inability to Fully Exchange Notice shall indicate (i) the
     reason why BSTI is unable to fully satisfy such holder's Exchange Notice,
     (ii) the number of shares of Common Stock which cannot be exchanged, and
     (iii) the Mandatory Redemption Price. Such holder must, within five (5)
     Trading Days of receipt of such Inability to Fully Exchange Notice, deliver
     written notice via facsimile to BSTI ("NOTICE IN RESPONSE TO INABILITY TO
     EXCHANGE") of its election pursuant to Section 11(a) above.

          (c) PAYMENT OF REDEMPTION PRICE.  If such holder shall elect to have
     its shares redeemed pursuant to Section 11(a) above, BSTI shall pay the
     Mandatory Redemption Price in cash to such holder within thirty (30) days
     of BSTI's receipt of the holder's Notice in Response to Inability to
     Exchange (the "MANDATORY REDEMPTION PRICE DEADLINE"). If BSTI shall fail to
     pay the applicable Mandatory Redemption Price to such holder on a timely
     basis as described in this Section 11(c) (other than pursuant to a dispute
     as to the determination of the Closing Bid Price or the arithmetic
     calculation of the Redemption Rate), such unpaid amount shall bear interest
     at the rate of 1% for the first month and a rate of 2.0% per month
     thereafter (prorated for partial months) until paid in full. Following the
     Mandatory Redemption Price Deadline, until the full Mandatory Redemption
     Price is paid in full to such holder, such holder may void the Mandatory
     Redemption with respect to those shares of Common Stock for which the full
     Mandatory Redemption Price has not been paid and receive back such shares
     of Common Stock.

          (d) PRO-RATA EXCHANGE AND REDEMPTION.  In the event the Company and
     BSTI each receives an Exchange Notice from more than one holder of Common
     Stock on the same day and BSTI can exchange and redeem some, but not all,
     of the Common Stock pursuant to this Section 11, BSTI shall exchange and
     redeem from each holder of Common Stock electing to have Common Stock
     exchanged and redeemed at such time an amount equal to such holder's
     pro-rata amount (based on the number of shares of Common Stock held by such
     holder relative to the number of shares of Common Stock outstanding,
     pursuant to this Agreement) of all Common Stock being exchanged and
     redeemed at such time.

<PAGE>   220

     12. ONE-TIME RIGHT TO SUSPEND EXCHANGE RIGHT OR EXCHANGE COMMON STOCK INTO
CONVERSION SHARES.

     Notwithstanding anything contained herein to the contrary, BSTI shall have
the one-time right, without payment or penalty of any kind, for a period of
thirty (30) days from the date written notice is given to the holders of Common
Stock, to suspend the Exchange Right in the event that the Company has received
a letter of intent by the Exchange Commencement Date from a reputable investment
banking firm to underwrite the public offering of the Company's common stock or
other securities ("PUBLIC OFFERING"), and the Public Offering has not occurred
by the Exchange Commencement Date due to market conditions as determined by such
underwriter.

     13. SUSPENSION OF EXCHANGE RIGHT UPON REGISTRATION OF COMMON STOCK OF THE
COMPANY UNDER THE 1934 ACT.

     Notwithstanding anything contained herein to the contrary, so long as (i)
the Company becomes and remains a reporting company under the 1934 Act, (ii) the
Company has its Form 8A declared effective by the SEC, and (iii) the trading
price of the Common Stock as reported by Bloomberg on its principal exchange or
trading market remains equal to or greater than $6.19 per share, the holders of
the Common Stock shall have no Exchange Right.

     14. REISSUANCE OF CERTIFICATES.

     In the event of an exchange or redemption pursuant to this Agreement of
less than all of the Common Stock represented by a particular Common Stock
certificate, the Company shall promptly cause to be issued and delivered, to the
holder of such Common Stock, a Common Stock certificate representing the
remaining shares of Common Stock which have not been so exchanged or redeemed.

     15. TRANSFER AGENT INSTRUCTIONS.

     BSTI shall issue irrevocable instructions to its transfer agent to issue
certificates, registered in the name of the Buyer or its respective nominee(s),
for the Conversion Shares in such amounts as specified from time to time by the
Buyer to the Company upon conversion of the Common Stock (the "Irrevocable
Transfer Agent Instructions"), except as provided in Sections 9, 10, 11, 12, and
15 herein. Prior to registration of the Conversion Shares under the 1933 Act,
all such certificates shall bear the restrictive legend specified in Section
2(g) of this Agreement. The Company and BSTI warrant that no instruction other
than the Irrevocable Transfer Agent Instructions referred to in this Section 15,
and stop transfer instructions to give effect to Section 2(f) hereof (in the
case of the Conversion Shares, prior to registration of such shares under the
1933 Act) will be given by the Company or BSTI to its transfer agent and that
the Common Stock and the Conversion Shares shall otherwise be freely
transferable on the books and records of the Company and BSTI as and to the
extent provided in this Agreement and the Registration Rights Agreement. Nothing
in this Section 15 shall affect in any way the Buyer's obligations and agreement
to comply with all applicable securities laws upon resale of the Common Stock or
Conversion Shares. If the Buyer provides the Company and BSTI with an opinion of
counsel, reasonably satisfactory in form, and substance to the Company, that
registration of a resale by the Buyer of any of the Common Stock or Conversion
Shares is not required under the 1933 Act, the Company shall permit the
transfer, and, in the case of the Conversion Shares, BSTI shall promptly
instruct its transfer agent to issue one or more certificates in such name and
in such denominations as specified by the Buyer. The

                                      F-21
<PAGE>   221

Company and BSTI acknowledge that a breach by it of its obligations hereunder
will cause irreparable harm to the Buyer by vitiating the intent and purpose of
the transaction contemplated hereby. Accordingly, the Company and BSTI
acknowledge that the remedy at law for a breach of its obligations under this
Section 15 will be inadequate and agrees, in the event of a breach or threatened
breach by the Company or BSTI of the provisions of this Section 15, that the
Buyer shall be entitled, in addition to all other available remedies, to an
injunction restraining any breach and requiring immediate issuance and transfer,
without the necessity of showing economic loss and without any bond or other
security being required.

     16. CONFIDENTIALITY.

          a. NONDISCLOSURE.  As much of the information and other material
     furnished under or in connection with this Agreement (whether furnished
     before, on or after the date hereof) as constitutes or contains
     confidential business, financial or other information of the Company, BSTI
     or its subsidiaries, each Buyer covenants for itself, and, as applicable,
     for its directors, officers, affiliates and partners, that it will use due
     care to prevent its officers, directors, partners, employees, counsel,
     accountants and other representatives from disclosing such information to
     persons other than their respective authorized employees, counsel,
     accountants, shareholders, partners, limited partners and other authorized
     representatives. Notwithstanding the foregoing, if a Buyer is advised by
     such counsel that such disclosure or delivery is required by law,
     regulation or judicial or administrative order, then they may disclose or
     deliver such information or other after giving written notice to the
     Company and BSTI of such requirements. For purposes of this Section 10a.,
     "due care" means at least the same level of care that a Buyer would use to
     protect the confidentiality of its own sensitive or proprietary
     information, and this obligation shall survive termination of this
     Agreement.

          b. POSSESSION OF MATERIAL, NON-PUBLIC INFORMATION.  To the extent that
     any of the information furnished by the Company or BSTI to the Buyers
     hereof would constitute material, nonpublic information for purposes of the
     Exchange Act, Buyers agree not to engage in any purchase or sale of
     securities while in possession of such information and prior to the time
     that such information is made generally known to the public and Buyers
     agree to use due care to prevent their officers, directors, partners,
     employees, counsel and other representatives, who have been given access to
     such material, nonpublic information, from engaging in any such purchase or
     sale during such period.

     17. GOVERNING LAW: MISCELLANEOUS.

          a. GOVERNING LAW.  This Agreement shall be governed by and interpreted
     in accordance with the laws of the State of Georgia without regard to the
     principles of conflict of laws. Buyer may at any time and at its option,
     whether or not an arbitration action is then pending, initiate a civil
     action for temporary and permanent injunctive and other equitable relief
     against Company and BSTI. Company and BSTI acknowledges that upon any
     breach of Buyer's conversion rights hereunder, Buyer's resulting injury may
     not be adequately compensated by a remedy at law. Accordingly, upon such
     breach, Buyer, at its election and without limitation of its other
     remedies, shall be entitled to pursue a claim for specific performance of
     this Agreement, and Company and BSTI hereby waive the right to assert any
     defense thereto that Purchaser has an adequate remedy at law. The parties
     further agree that any action

                                      F-22
<PAGE>   222

     between them shall be heard in Atlanta, Georgia, and expressly consent to
     the jurisdiction and venue of the Superior Court of Fulton County, Georgia,
     and the United States District Court for the Northern District of Georgia,
     Atlanta Division for the adjudication of any civil action asserted pursuant
     to this Paragraph.

          b. COUNTERPARTS.  This Agreement may be executed in two or more
     identical counterparts, all of which shall be considered one and the same
     agreement and shall become effective when counterparts have been signed by
     each party and delivered to the other party. In the event any signature
     page is delivered by facsimile transmission, the party using such means of
     delivery shall cause four (4) additional original executed signature pages
     to be physically delivered to the other party within five (5) days of the
     execution and delivery hereof.

          c. HEADINGS.  The headings of this Agreement are for convenience of
     reference and shall not form part of, or affect the interpretation of, this
     Agreement.

          d. SEVERABILITY.  If any provision of this Agreement shall be invalid
     or unenforceable in any jurisdiction, such invalidity or unenforceability
     shall not affect the validity or enforceability of the remainder of this
     Agreement in that jurisdiction or the validity or enforceability of any
     provision of this Agreement in any other jurisdiction.

          e. ENTIRE AGREEMENT, AMENDMENTS.  This Agreement supersedes all other
     prior oral or written agreements between the Buyer, the Company, their
     affiliates and persons acting on their behalf with respect to the matters
     discussed herein, and this Agreement and the instruments referenced herein
     contain the entire understanding of the parties with respect to the matters
     covered herein and therein and, except as specifically set forth herein or
     therein, neither the Company nor any Buyer makes any representation,
     warranty, covenant or undertaking with respect to such matters. No
     provision of this Agreement may be waived or amended other than by an
     instrument in writing signed by the party to be charged with enforcement.

          j. PUBLICITY.  The Company, BSTI, and the Buyer shall have the right
     to approve before issuance any press releases or any other public
     statements with respect to the transactions contemplated hereby; provided,
     however, that the Company shall be entitled, without the prior approval of
     the Buyer, to make any press release or other public disclosure with
     respect to such transactions as is required by applicable law and
     regulations (although the Buyer shall be consulted by the Company in
     connection with any such press release or other public disclosure prior to
     its release and shall be provided with a copy thereof).

          k. FURTHER ASSURANCES.  Each party shall do and perform, or cause to
     be done and performed, all such further acts and things, and shall execute
     and deliver all such other agreements, certificates, instruments and
     documents, as the other party may reasonably request in order to carry out
     the intent and accomplish the purposes of this Agreement and the
     consummation of the transactions contemplated hereby.

          l. TERMINATION.  In the event that the Closing shall not have occurred
     with respect to the Buyer on or before five (5) business days from the date
     hereof due to the Company's or the Buyer's failure to satisfy the
     conditions set forth in Sections 5 and 6 above (and the nonbreaching
     party's failure to waive such unsatisfied

                                      F-24
<PAGE>   224

     condition(s)), the nonbreaching party shall have the option to terminate
     this Agreement with respect to such breaching party at the close of
     business on such date without liability of any party to any other
     party-provided.

          m. INDEPENDENT COUNSEL.  The parties to this Agreement acknowledge
     that Company and BSTI have received independent counsel from the law firm
     of Sims Moss Kline & Davis LLP which is acting as their counsel. Buyers
     have been advised by Sims Moss Kline & Davis LLP to seek independent advice
     with respect to the terms and conditions of this Agreement and any related
     agreements before signing them.

          n. NO STRICT CONSTRUCTION.  The language used in this Agreement will
     be deemed to be the language chosen by the parties to express their mutual
     intent, and no rules of strict construction will be applied against any
     party.

Purchase Agreement to be duly executed as of the date first written above.

                         REGISTRATION RIGHTS AGREEMENT

into          shares of the Company's common stock, no par value per share (as

applicable state securities laws:

          NOW, THEREFORE, in consideration of the premises and the mutual
     covenants contained herein and other good and valuable consideration, the
     receipt and sufficiency of which are hereby acknowledged, the Company and
     the Buyer hereby agree as follows:

     1. DEFINITIONS.

     As used in this Agreement, the following terms shall have the following
meanings:

          a. "INVESTOR" means the Buyer and any transferee or assignee thereof
     to whom the Buyer assigns its rights under this Agreement and who agrees to
     become bound by the provisions of this Agreement in accordance with Section
     9.

          b. "PERSON" means a corporation, a limited liability company, an
     association, a partnership, an organization, a business, an individual, a
     governmental or political subdivision thereof or a governmental agency.

          c. "REGISTER," "REGISTERED," and "REGISTRATION" refer to a
     registration effected by preparing and filing one or more Registration
     Statements in compliance with the 1933 Act and pursuant to Rule 415 under
     the 1933 Act or any successor rule providing for offering securities on a
     continuous basis ("RULE 415"), and the declaration or ordering of
     effectiveness of such Registration Statement(s) by the United States
     Securities and Exchange Commission (the "SEC").

          d. REGISTRABLE SECURITIES" means exclusively the Conversion Shares
     issued or issuable upon conversion of the Common Stock and any shares of

                                       G-1
<PAGE>   240

     or issuable with respect to the Conversion Shares or the Common Stock as a
     result of any stock split, stock dividend, recapitalization, exchange or
     similar event.

          e. "REGISTRATION STATEMENT" means a registration statement of the
     Company filed under the 1933 Act.

     Capitalized terms used herein and not otherwise defined herein shall have
the respective meanings set for-the in the Securities Purchase Agreement.

     2. REGISTRATION.

          a. MANDATORY REGISTRATION.  No later than December 31, 1999, (the
     "FILING DEADLINE"), the Company shall prepare and file with the SEC a
     Registration Statement or Registration Statements (as is necessary) on Form
     S-3 (or, if such form is unavailable for such a registration, on such other
     form as is available for such a registration, subject to the consent of
     each Buyer and the provisions of Section 2(e), which consent will not be
     unreasonably withheld), covering the resale of all of the Registrable
     Securities and no other Securities of any kind by any person or entity,
     which Registration Statement(s) shall state that, in accordance with Rule
     416 promulgated under the 1933 Act, such Registration Statement(s) also
     covers such indeterminate number of additional shares of Common Stock as
     may become issuable to prevent dilution resulting from stock splits, stock
     dividends or similar transactions. Such Registration Statement shall
     initially register for resale 1,000,000 shares of Common Stock, subject to
     adjustment as provided in Section 3(b), and such registered shares of
     Common Stock shall be allocated among the Investors pro rata based on the
     total number of Registrable Securities issued or issuable as of each date
     that a Registration Statement, as amended, relating to the resale of the
     Registrable Securities is declared effective by the SEC. The Company shall
     use its best efforts to have the Registration Statement declared effective
     by the SEC within one hundred and twenty (120) days after the Filing
     Deadline (the "REGISTRATION DEADLINE"). The Company shall permit the
     registration statement to become effective within five (5) business days
     after receipt of a "no review" notice from the SEC. In the event that the
     Registration Statement is not declared effective by the SEC by the
     Registration Deadline then the Company shall pay a penalty to each Buyer
     equal to 2% of the purchase price for Common Stock purchased by each
     Investor and still held by each Buyer for each thirty (30) day period
     beyond the Registration Deadline that the Registration Statement is not
     declared effective by the SEC (the "REGISTRATION DEADLINE PENALTY"). The
     Registration Deadline Penalty shall be immediately payable by the Company
     on demand by the Investor in either cash or Common Stock of the Company at
     the election of the Company upon delivery to the Company of a notice of
     such default by the Investor.

          b. UNDERWRITTEN OFFERING.  If any offering pursuant to a Registration
     Statement pursuant to Section 2(a) involves an underwritten offering, the
     Buyers shall have the right to select one legal counsel to represent their
     interests in the offering, the costs of which shall be borne by the
     Investors.

          c. PIGGY-BACK REGISTRATIONS.  If at any time after the Exchange
     Commencement Date and prior to the expiration of the Registration Period
     (as hereinafter defined) the Company proposes to file with the SEC a
     Registration Statement relating to an offering for its own account or the
     account of others under the 1933 Act of any of its securities (other than
     on Form S-4 or Form S-8 or their then equivalents relating to

                                       G-2
<PAGE>   241

     securities to be issued solely in connection with any acquisition of any
     entity or business or equity securities issuable in connection with stock
     option or other employee benefit plans) the Company shall promptly send to
     each Investor who is entitled to registration rights under this Section
     2(c) written notice of the Company's intention to file a Registration
     Statement and of such Investor's rights under this Section 2(c) and, if
     within twenty (20) days after receipt of such notice, such Investor shall
     so request in writing, the Company shall include in such Registration
     Statement all or any part of the Registrable Securities such Investor
     requests to be registered, subject to the priorities set forth in Section
     2(d) below. No right to registration of Registrable Securities under this
     Section 2(c) shall be construed to limit any registration required under
     Section 2(a). The obligations of the Company under this Section 2(c) may be
     waived by Investors holding a majority of the Registrable Securities. If an
     offering in connection with which an Investor is entitled to registration
     under this Section 2(c) is an underwritten offering, then each Investor
     whose Registrable Securities are included in such Registration Statement
     shall, unless otherwise agreed by the Company, offer and sell such
     Registrable Securities in an underwritten offering using the same
     underwriter or underwriters and, subject to the provisions of this
     Agreement, on the same terms and conditions as other shares of Common Stock
     included in such underwritten offering.

          d. PRIORITY IN PIGGY-BACK REGISTRATION RIGHTS IN CONNECTION WITH
     REGISTRATIONS OR COMPANY ACCOUNT.  If the registration referred to in
     Section 2(c) is to be an underwritten public offering for the account of
     the Company and the managing underwriter(s) advise the Company in writing,
     that in their reasonable good faith opinion, marketing or other factors
     dictate that a limitation on the number of shares of Common Stock which may
     be included in the Registration Statement is necessary to facilitate and
     not adversely affect the proposed offering, then the Company shall include
     in such registration: (1) first, all securities the Company proposes to
     sell for its own account, (2) second, up to the full number of securities
     proposed to be registered for the account of the holders of securities
     entitled to inclusion of their securities in the Registration Statement by
     reason of demand registration rights, and (3) third, the securities
     requested to be registered by the Investors and other holders of securities
     entitled to participate in the registration, drawn from them pro rata based
     on the number each has requested to be included in such registration.

     3. RELATED OBLIGATIONS.

     Whenever an Investor has requested that any Registrable Securities be
registered pursuant to Section 2(c) or at such time as the Company is obligated
to file a Registration Statement with the SEC pursuant to Section 2(a), the
Company will use its best efforts to effect the registration of the Registrable
Securities in accordance with the intended method of disposition thereof and,
pursuant thereto, the Company shall have the following obligations:

          a. The Company shall promptly prepare and file with the SEC a
     Registration Statement with respect to the Registrable Securities (on or
     prior to the Filing Deadline) for the registration of Registrable
     Securities pursuant to Section 2(a)) and use its best efforts to cause such
     Registration Statement(s) relating to Registrable Securities to become
     effective as soon as possible after such filing (by the one hundred and
     twentieth (120th) day following the issuance of the relevant for the
     registration of Registrable Securities pursuant to Section 2(a), and keep
     the Registration Statement(s) effective pursuant to Rule 415 at all times
     until the later of

                                       G-3
<PAGE>   242

     (i) the date as of which the Investors may sell all of the Registrable
     Securities without restriction pursuant to Rule 144(k) promulgated under
     the 1933 Act (or successor thereto) or (ii) the date on which the Investors
     shall have sold all the Registrable Securities (the "REGISTRATION PERIOD"),
     which Registration Statement(s) (including any amendments or supplements
     thereto and prospectuses contained therein) shall 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 in which they were made, not misleading.

          b. The Company shall prepare and file with the SEC such amendments
     (including post-effective amendments) and supplements to the Registration
     Statement(s) and the prospectus(es) used in connection with the
     Registration Statement(s), which prospectus(es) are to be filed pursuant to
     Rule 424 promulgated under the 1933 Act, as may be necessary to keep the
     Registration Statement(s) effective at all times during the Registration
     Period, and, during such period, comply with the provisions of the 1933 Act
     with respect to the disposition of all Registrable Securities of the
     Company covered by the Registration Statement(s) until such time as all of
     such Registrable Securities shall have been disposed of in accordance with
     the intended methods of disposition by the seller or sellers thereof as set
     forth in the Registration Statement(s). In the event the number of shares
     available under a Registration Statement filed pursuant to this Agreement
     is insufficient to cover all of the Registrable Securities, the Company
     shall amend the Registration Statement, or file a new Registration
     Statement (on the short form available therefor, if applicable), or both,
     so as to cover all of the Registrable Securities, in each case, as soon as
     practicable, but in any event within thirty (30) days after the necessity
     therefor arises (based on the market price of the Common Stock and other
     relevant factors on which the Company reasonably elects to rely). The
     Company shall use its best efforts to cause such amendment and/or new
     Registration Statement to become effective as soon as practicable following
     the filing thereof. For purposes of the foregoing provision, the number of
     shares available under a Registration Statement shall be deemed
     "insufficient to cover all of the Registrable Securities" if at any time
     the number of Registrable Securities issued or issuable upon conversion of
     the Common Stock is greater than the quotient determined by dividing (i)
     the number of Conversion Shares available for resale under such
     Registration Statement by (ii) 1.0; provided that in the case of the
     initial registration of the Registrable Securities pursuant to Section
     2(a), the Company shall be required to register for resale 1,000,000 shares
     of Common Stock.

          c. The Company shall furnish to each Investor whose Registrable
     Securities are included in the Registration Statement(s) and its legal
     counsel without charge (i) promptly after the same is prepared and filed
     with the SEC at least one copy of the Registration Statement and any
     amendment thereto, including financial statements and schedules, all
     documents incorporated therein by reference and all exhibits, the
     prospectus(es) included in such Registration Statement(s) (including each
     preliminary prospectus ) and, with regards to the Registration Statement,
     any correspondence by or on behalf of the Company to the SEC or the staff
     of the SEC and any correspondence from the SEC or the staff of the SEC to
     the Company or its representatives, (ii) upon the effectiveness of any
     Registration Statement, ten (10) copies of the prospectus included in such
     Registration Statement and all amendments and supplements thereto (or such
     other number of copies as such Investor may reasonably request) and (iii)
     such other documents, including any

                                       G-4
<PAGE>   243

     preliminary prospectus, as such Investor may reasonably request in order to
     facilitate the disposition of the Registrable Securities owned by such
     Investor.

          d. The Company shall use reasonable efforts to (i) register and
     qualify the Registrable Securities covered by the Registration Statement(s)
     under the securities or "blue sky" laws of such jurisdictions in the United
     States as any Investor reasonably requests, (ii) prepare and file in those
     jurisdictions, such amendments (including post-effective amendments) and
     supplements to such registrations and qualifications as may be necessary to
     maintain the effectiveness thereof during the Registration Period, (iii)
     take such other actions as may be necessary to maintain such registrations
     and qualifications in effect at all times during the Registration Period,
     and (iv) take all other actions reasonably necessary or advisable to
     quality the Registrable Securities for sale in such jurisdictions;
     provided, however, that the Company shall not be required in connection
     therewith or as a condition thereto to (a) qualify to do business in any
     jurisdiction where it would not otherwise be required to qualify but for
     this Section 3(d), (b) subject itself to general taxation in any such
     jurisdiction, or (c) file a general consent to service of process in any
     such jurisdiction. The Company shall promptly notify each Investor who
     holds Registrable Securities of the receipt by the Company of any
     notification with respect to the suspension of the registration or
     qualification of any of the Registrable Securities for sale under the
     securities or "blue sky" laws of any jurisdiction in the United States or
     its receipt of actual notice of the initiation or threatening of any
     proceeding for such purpose.

     e. [LEFT INTENTIONALLY BLANK]

          f. As promptly as practicable after becoming aware of such event, the
     Company shall notify each Investor in writing of the happening of any
     event, of which the Company has knowledge, as a result of which the
     prospectus included in a Registration Statement, as then in effect,
     includes an untrue statement of a material fact or omission 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, and promptly prepare a supplement or amendment to the
     Registration Statement to correct such untrue statement or omission, and
     deliver ten (10) copies of such supplement or amendment to each Investor
     (or such other number of copies as such Investor may reasonably request).
     The Company shall also promptly notify each Investor in writing (i) when a
     prospectus or any prospectus supplement or post-effective amendment has
     been filed, and when a Registration Statement or any post-effective
     amendment has become effective (notification of such effectiveness shall be
     delivered to each Investor by facsimile on the same day of such
     effectiveness and by overnight mail) (ii) of any request by the SEC for
     amendments or supplements to a Registration Statement or related prospectus
     or related information, (iii) of the Company's reasonable determination
     that a post-effective amendment to a Registration Statement would be
     appropriate.

          g. The Company shall use its best efforts to prevent the issuance of
     any stop order or other suspension of effectiveness of a Registration
     Statement, or the suspension of the qualification of any of the Registrable
     Securities for sale in any jurisdiction and, if such an order or suspension
     is issued, to obtain the withdrawal of such order or suspension at the
     earliest possible moment and to notify each Investor who holds Registrable
     Securities being sold (and, in the event of an underwritten offering, the
     managing underwriters) of the issuance of such order and the resolution

                                       G-5
<PAGE>   244

     thereof or its receipt of actual notice of the initiation or threat of any
     proceeding for such purpose.

          h. The Company shall permit each Investor at such Investors expense a
     single firm of counsel or such other counsel as thereafter designated as
     selling stockholders' counsel by the Investors who hold a majority of the
     Registrable Securities being sold, to review and comment upon the
     Registration Statement(s) and all amendments and supplements thereto at
     least seven (7) days prior to their filing with the SEC.

          i. At the request of the Investors who hold a majority of the
     Registrable Securities being sold, the Company shall furnish, on the date
     that Registrable Securities are delivered to an underwriter, if any, for
     sale in connection with the Registration Statement (i) if required by an
     underwriter, a letter, dated such date, from the Company's independent
     certified public accountants in form and substance as is customarily given
     by independent certified public accountants to underwriters in an
     underwritten public offering, addressed to the underwriters, and (ii) an
     opinion, dated as of such date, of counsel representing the Company for
     purposes of such Registration Statement, in form, scope and substance as is
     customarily given in an underwritten public offering, addressed to the
     underwriters and the Investors.

          j. The Company shall make available for inspection by (i) any
     Investor, (ii) any underwriter participating in any disposition pursuant to
     a Registration Statement, (iii) one firm of attorneys and one firm of
     accountants or other agents retained by the Investors, and (iv) one firm of
     attorneys retained by all such underwriters (collectively, the
     "INSPECTORS") all pertinent financial and other records, and pertinent
     corporate documents and properties of the Company (collectively, the
     "RECORDS"), as shall be reasonably deemed necessary by each Inspector to
     enable each Inspector to exercise its due diligence responsibility, and
     cause the Company's officers, directors and employees to supply all
     information which any Inspector may reasonably request for purposes of such
     due diligence provided, however, that each Inspector shall hold in strict
     confidence and shall not make any disclosure (except to an Investor) or use
     of any Record or other information which the Company determines in good
     faith to be confidential, and of which determination the Inspectors are so
     notified, unless (a) the disclosure of such Records is necessary to avoid
     or correct a misstatement or omission in any Registration Statement or is
     otherwise required under the 1933 Act, (b) the release of such Records is
     ordered pursuant to a final, non-appealable subpoena or order from a court
     or government body of competent jurisdiction, or (c) the information in
     such Records has been made generally available to the public other than by
     disclosure in violation of this or any other agreement. Each Investor
     agrees that it shall, upon learning that disclosure of such Records is
     sought in or by a court or governmental body of competent jurisdiction or
     through other means, give prompt notice to the Company and allow the
     Company, at its expense, to undertake appropriate action to prevent
     disclosure of, or to obtain a protective order for, the Records deemed
     confidential. All fees, costs and expenses of the foregoing shall be borne
     by the Investors.

          k. The Company shall hold in confidence and not make any disclosure of
     information concerning an Investor provided to the Company unless (i)
     disclosure of such information is necessary to comply with federal or state
     securities laws, (ii) the disclosure of such information is necessary to
     avoid or correct a misstatement or omission in any Registration Statement,
     (iii) the release of such information is ordered pursuant to a subpoena or
     other final, non-appealable order from a court or

                                       G-6
<PAGE>   245

     governmental body of competent jurisdiction, or (iv) such information has
     been made generally available to the public other than by disclosure in
     violation of this or any other agreement. The Company agrees that it shall,
     upon learning that disclosure of such information concerning an Investor is
     sought in or by a court or governmental body of competent jurisdiction or
     through other means, give prompt written notice to such Investor and allow
     such Investor, at the Investor's expense, to undertake appropriate action
     to prevent disclosure of, or to obtain a protective order for, such
     information.

          l. The Company shall use reasonable efforts either to (i) cause all
     the Registrable Securities covered by a Registration Statement to be listed
     on each national securities exchange on which securities of the same class
     or series issued by the Company are then listed, if any, if the listing of
     such Registrable Securities is then permitted under the rules of such
     exchange, (ii) to secure designation and quotation of all the Registrable
     Securities covered by the Registration Statement on the Nasdaq National
     Market System, (iii) if, despite the Company's reasonable efforts to
     satisfy the preceding clause (i) or (ii), the Company is unsuccessful in
     satisfying the preceding clause (i) or (ii) to secure the inclusion for
     quotation on the Nasdaq SmallCap Market for such Registrable Securities or,
     (iv) if, despite the Company's reasonable efforts to satisfy the preceding
     clause (iii), the Company is unsuccessful in satisfying the preceding
     clause (iii), to secure the inclusion for quotation on the over-the-counter
     market for such Registrable Securities, and, without limiting the
     generality of the foregoing, in the case of clause (iii) or (iv), to
     arrange for at least two market makers to register with the National
     Association of Securities Dealers, Inc. ("NASD") as such with respect to
     such Registrable Securities. The Company shall pay all fees and expenses in
     connection with satisfying its obligation under this Section 3(l).

          m. The Company shall cooperate with the Investors who hold Registrable
     Securities being offered and, to the extent applicable, any managing
     underwriter or underwriters, to facilitate the timely preparation and
     delivery of certificates (not bearing any restrictive legend) representing
     the Registrable Securities to be offered pursuant to a Registration
     Statement and enable such certificates to be in such denominations or
     amounts, as the case may be, as the managing underwriter or underwriters,
     if any, or, if there is no managing underwriter or underwriters, the
     Investors may reasonably request and registered in such names as the
     managing underwriter or underwriters, if any, or the Investors may request.
     Not later than the date on which any Registration Statement registering the
     resale of Registrable Securities is declared effective, the Company shall
     deliver to its transfer agent instructions, accompanied by any reasonably
     required opinion of counsel, that permit sales of unlegended securities in
     a timely fashion that complies with then mandated securities settlement
     procedures for regular way market transactions.

          n. The Company shall take all other reasonable actions necessary to
     expedite and facilitate disposition by the Investors of Registrable
     Securities pursuant to a Registration Statement.

          o. The Company shall provide a transfer agent and registrar of all
     such Registrable Securities not later than the effective date of such
     Registration Statement.

          p. If requested by the managing underwriters of an Investor, the
     Company shall immediately incorporate in a prospectus supplement or
     post-effective amendment such

                                       G-7
<PAGE>   246

     information as the managing underwriters and the Investors agree should be
     included therein relating to the sale and distribution of Registrable
     Securities, including, without limitation, information with respect to the
     number of Registrable Securities being sold to such underwriters, the
     purchase price being paid therefor by such underwriters and with respect to
     any other terms of the underwritten (or best efforts underwritten) offering
     of the Registrable Securities to be sold in such offering; make all
     required filings of such prospectus supplement or post-effective amendment
     as soon as notified of the matters to be incorporated in such prospectus
     supplement or post-effective amendment; and supplement or make amendments
     to any Registration Statement if requested by a shareholder or any
     underwriter of such Registrable Securities. The costs of preparation and
     filing of any such post-effective amendments and supplements shall be borne
     by the Investors.

          q. The Company shall use its best efforts to cause the Registrable
     Securities covered by the applicable Registration Statement to be
     registered with or approved by such other governmental agencies or
     authorities as may be necessary to consummate the disposition of such
     Registrable Securities.

          r. The Company shall otherwise use its best efforts to comply with all
     applicable rules and regulations of the SEC in connection with any
     registration hereunder.

     4. OBLIGATIONS OF THE INVESTORS.

          a. At least seven (7) days prior to the first anticipated filing date
     of the Registration Statement, the Company shall notify each Investor in
     writing of the information the Company requires from each such Investor if
     such Investor elects to have any of such Investor's Registrable Securities
     included in the Registration Statement. It shall be a condition precedent
     to the obligations of the Company to complete the registration pursuant to
     this Agreement with respect to the Registrable Securities of a particular
     Investor that such Investor shall furnish to the Company such information
     regarding itself, the Registrable Securities held by it and the intended
     method of disposition of the Registrable Securities held by it as shall be
     reasonably required to effect the registration of such Registrable
     Securities and shall execute such documents in connection with such
     registration as the Company may reasonably request.

          b. Each Investor by such Investor's acceptance of the Registrable
     Securities agrees to cooperate with the Company as reasonably requested by
     the Company in connection with the preparation and filing of the
     Registration Statement(s) hereunder, unless such Investor has notified the
     Company in writing of such Investor's election to exclude all of such
     Investor's Registrable Securities from the Registration Statement.

          c. Each Investor agrees to enter into and perform such Investor's
     obligations under an underwriting agreement, in usual and customary form,
     including, without limitation, customary indemnification and contribution
     obligations, with the managing underwriter of such offering and take such
     other actions as are reasonably required in order to expedite or facilitate
     the disposition of the Registrable Securities, unless such Investor
     notifies the Company in writing of such Investor's election to exclude all
     of such Investor's Registrable Securities from the Registration
     Statement(s).

          d. Each Investor agrees that, upon receipt of any notice from the
     Company of the happening of any event of the kind described in Section 3(g)
     or the first sentence of 3(f), such Investor will immediately discontinue
     disposition of Registrable

                                       G-8
<PAGE>   247

     Securities pursuant to the Registration Statement(s) covering such
     Registrable Securities until such Investor's receipt of the copies of the
     supplemented or amended prospectus contemplated by Section 3(g) or the
     first sentence of 3(f) and, if so directed by the Company, such Investor
     shall deliver to the Company (at the expense of the Company) or destroy all
     copies in such Investor's possession, of the prospectus covering such
     Registrable Securities current at the time of receipt of such notice.

          e. No Investor may participate in any underwritten registration
     hereunder unless such Investor (i) agrees to sell such Investor's
     Registrable Securities on the basis provided in any underwriting
     arrangements approved by the Investors entitled hereunder to approve such
     arrangements, (ii) completes and executes all questionnaires, powers of
     attorney, indemnities, underwriting agreements and other documents
     reasonably required under the terms of such underwriting arrangements, and
     (iii) agrees to pay its pro rata share of all underwriting discounts and
     commissions.

     5. EXPENSES OF REGISTRATION.

     All reasonable expenses, other than underwriting discounts and commissions,
incurred in connection with registrations, filings or qualifications pursuant to
Sections 2 and 3, including, without limitation, all registration, listing and
qualifications fees, printers and accounting fees, and fees and disbursements of
counsel for the Company shall be borne by the Company except as otherwise
specifically provided herein.

     6. INDEMNIFICATION

     In the event any Registrable Securities are included in a Registration
Statement under this Agreement:

          a. To the fullest extent permitted by law, the Company will, and
     hereby does, indemnify, hold harmless and defend each Investor who holds
     such Registrable Securities, the directors, officers, partners, employees,
     agents and each Person, if any, who controls any Investor within the
     meaning of the 1933 Act or the Securities Exchange Act of 1934, as amended
     (the "1934 ACT"), and any underwriter (as defined in the 1933 Act) for the
     Investors, and the directors and officers of, and each Person, if any, who
     controls, any such underwriter within the meaning of the 1933 Act or the
     1934 Act (each, an "INDEMNIFIED PERSON"), against any losses, claims,
     damages, liabilities, judgments, fines, penalties, charges, costs,
     attorneys' fees, amounts paid in settlement or expenses, joint or several,
     (collectively, "CLAIMS") incurred in investigating, preparing or defending
     any action, claim, suit, inquiry, proceeding, investigation or appeal taken
     from the foregoing by or before any court or governmental, administrative
     or other regulatory agency, body or the SEC, whether pending or threatened,
     whether or not an indemnified party is or may be a party thereto
     ("INDEMNIFIED DAMAGES"), to which any of them may become subject insofar as
     such Claims (or actions or proceedings, whether commenced or threatened, in
     respect thereof) arise out of or are based upon: (i) any untrue statement
     or alleged untrue statement of a material fact in a Registration Statement
     or any post-effective amendment thereto or in any filing made in connection
     with the qualification of the offering under the securities or other "blue
     sky" laws of any jurisdiction in which Registrable Securities are offered
     ("BLUE SKY FILING"), or the omission or alleged omission to state a
     material fact required to be stated therein or necessary to make the
     statements therein, in light of the circumstances under which the
     statements therein were made, not misleading, (ii) any untrue statement or
     alleged untrue

                                       G-9
<PAGE>   248

     statement of a material fact contained in any preliminary prospectus if
     used prior to the effective date of such Registration Statement, or
     contained in the final prospectus (as amended or supplemented, if the
     Company files any amendment thereof or supplement thereto with the SEC) or
     the omission or alleged omission to state therein any material fact
     necessary to make the statements made therein, in light of the
     circumstances under which the statements therein were made, not misleading,
     or (iii) any violation or alleged violation by the Company of the 1933 Act,
     the 1934 Act, any other law, including, without limitation, any state
     securities law, or any rule or regulation thereunder relating to the offer
     or sale of the Registrable Securities pursuant to a Registration Statement
     (the matters in the foregoing clauses (i) through (iii) being,
     collectively, "VIOLATIONS"). Subject to the restrictions set forth in
     Section 6(d) with respect to the number of legal counsel, the Company shall
     reimburse the Investors and each such underwriter or controlling person,
     promptly as such expenses are incurred and are due and payable, for any
     legal fees or other reasonable expenses incurred by them in connection with
     investigating or defending any such Claim. Notwithstanding anything to the
     contrary contained herein, the indemnification agreement contained in this
     Section 6(a): (i) shall not apply to a Claim arising out of or based upon a
     Violation which occurs in reliance upon and in conformity with information
     furnished in writing to the Company by any Indemnified Person or
     underwriter for such Indemnified Person expressly for use in connection
     with the preparation of the Registration Statement or any such amendment
     thereof or supplement thereto, if such prospectus was timely made available
     by the Company pursuant to Section 3(c); (ii) with respect to any
     preliminary prospectus, shall not inure to the benefit of any such person
     from whom the person asserting any such Claim purchased the Registrable
     Securities that are the subject thereof (or to the benefit of any person
     controlling such person) if the untrue statement or mission of material
     fact contained in the preliminary prospectus was corrected in the
     prospectus, as then amended or supplemented, if such prospectus was timely
     made available by the Company pursuant to Section 3(c), and the Indemnified
     Person was promptly advised in writing not to use the incorrect prospectus
     prior to the use giving rise to a violation and such Indemnified Person,
     notwithstanding such advice, used it; (iii) shall not be available to the
     extent such Claim is based on a failure of the Investor to deliver or to
     cause to be delivered the prospectus made available by the Company; and
     (iv) shall not apply to amounts paid in settlement of any Claim if such
     settlement is effected without the prior written consent of the Company,
     which consent shall not be unreasonably withheld. Such indemnity shall
     remain in full force and effect regardless of any investigation made by or
     on behalf of the Indemnified Person and shall survive the transfer of the
     Registrable Securities by the Investors pursuant to Section 9 for a period
     of three (3) years from the Filing Deadline.

          b. In connection with any Registration Statement in which an Investor
     is participating, each such Investor agrees to severally and not jointly
     indemnify, hold harmless and defend, to the same extent and in the same
     manner as is set forth in Section 6(a), the Company, each of its directors,
     each of its officers who signs the Registration Statement, each Person, if
     any, who controls the Company within the meaning of the 1933 Act or the
     1934 Act (collectively and together with an Indemnified Person, an
     "INDEMNIFIED PARTY"), against any Claim or Indemnified Damages to which any
     of them may become subject, under the 1933 Act, the 1934 Act or otherwise,
     insofar as such Claim or Indemnified Damages arise out of or are based upon
     any Violation, in each case to the extent, and only to the extent, that
     such Violation occurs in reliance upon and in conformity with written
     information furnished

                                      G-10
<PAGE>   249

     to the Company by such Investor expressly for use in connection with such
     Registration Statement; and, subject to Section 6(d), such Investor will
     reimburse any legal or other expenses reasonably incurred by them in
     connection with investigating or defending any such Claim; provided,
     however, that the indemnity agreement contained in this Section 6(b) and
     Section 7 shall not apply to amounts paid in settlement of any Claim if
     such settlement is effected without the prior written consent of such
     Investor, which consent shall not be unreasonably withheld. Such indemnity
     shall remain in full force and effect regardless of any investigation made
     by or on behalf of such Indemnified Party and shall survive the transfer of
     the Registrable Securities by the Investors pursuant to Section 9.
     Notwithstanding anything to the contrary contained herein, the
     indemnification agreement contained in this Section 6(b) with respect to
     any preliminary prospectus shall not inure to the benefit of any
     Indemnified Party if the untrue statement or omission of material fact
     contained in the preliminary prospectus was corrected on a timely basis in
     the prospectus, as then amended or supplemented.

          c. The Company shall be entitled to receive indemnities from
     underwriters, selling brokers, dealer managers and similar securities
     industry professionals participating in any distribution, to the same
     extent as provided above, with respect to information such persons so
     furnished in writing expressly for inclusion in the Registration Statement.

          d. Promptly after receipt by an Indemnified Person or Indemnified
     Party under this Section 6 of notice of the commencement of any action or
     proceeding (including any governmental action or proceeding) involving a
     Claim such Indemnified Person or Indemnified Party shall, if a Claim in
     respect thereof is to be made against any indemnifying party under this
     Section 6, deliver to the indemnifying party a written notice of the
     commencement thereof, and the indemnifying party shall have the right to
     participate in, and, to the extent the indemnifying party so desires,
     jointly with any other indemnifying party similarly noticed, to assume
     control of the defense thereof with counsel mutually satisfactory to the
     indemnifying party and the Indemnified Person or the Indemnified Party, as
     the case may be; provided, however, that an Indemnified Person or
     Indemnified Party shall have the right to retain its own counsel with the
     fees and expenses to be paid by the indemnifying party, if, in the
     reasonable opinion of counsel retained by the indemnifying party, the
     representation by such counsel of the Indemnified Person or Indemnified
     Party and the indemnifying party would be inappropriate due to actual or
     potential differing interests between such Indemnified Person or
     Indemnified Party and any other party represented by such counsel in such
     proceeding. The Company shall pay reasonable fees for only one separate
     legal counsel for the Investors, and such legal counsel shall be selected
     by the Investors holding a majority in interest of the Registrable
     Securities included in the Registration Statement to which the Claim
     relates. The Indemnified Party or Indemnified Person shall cooperate fully
     with the indemnifying party in connection with any negotiation or defense
     of any such action or claim by the indemnifying party and shall furnish to
     the indemnifying party all information reasonably available to the
     Indemnified Party or Indemnified Person which relates to such action or
     claim. The indemnifying party shall keep the Indemnified Party or
     Indemnified Person fully apprised at all times as to the status of the
     defense or any settlement negotiations with respect thereto. No
     indemnifying party shall be liable for any settlement of any action, claim
     or proceeding effected without its written consent, provided, however, that
     the indemnifying party shall not unreasonably withhold, delay or condition
     its consent. No

                                      G-11
<PAGE>   250

     indemnifying party shall, without the consent of the Indemnified Party or
     Indemnified Person, consent to entry of any judgment or enter into any
     settlement or other compromise which does not include as an unconditional
     term thereof the giving by the claimant or plaintiff to such Indemnified
     Party or Indemnified Person of a release from all liability in respect to
     such claim or litigation. Following indemnification as provided for
     hereunder, the indemnifying party shall be subrogated to all rights of the
     Indemnified Party or Indemnified Person with respect to all third parties,
     firms or corporations relating to the matter for which indemnification has
     been made. The failure to deliver written notice to the indemnifying party
     within a reasonable time of the commencement of any such action shall not
     relieve such indemnifying party of any liability to the Indemnified Person
     or Indemnified Party under this Section 6, except to the extent that the
     indemnifying party is prejudiced in its ability to defend such action.

          e. The indemnification required by this Section 6 shall be made by
     periodic payments of the amount thereof during the course of the
     investigation or defense, as and when bills are received or Indemnified
     Damages are incurred.

          f. The indemnity agreements contained herein shall be in addition to
     (i) any cause of action or similar right of the Indemnified Party or
     Indemnified Person against the indemnifying party or others, and (ii) any
     liabilities the indemnifying party may be subject to pursuant to the law.

     7. CONTRIBUTION.

     To the extent any indemnification by an indemnifying party is prohibited or
limited by law, the indemnifying party agrees to make the maximum contribution
with respect to any amounts for which it would otherwise be liable under Section
6 to the fullest extent permitted by law; provided, however, that: (i) no
contribution shall be made under circumstances where the maker would not have
been liable for indemnification under the fault standards set forth in Section
6; (ii) no seller of Registrable Securities guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution from any seller of Registrable Securities who was not
guilty of fraudulent misrepresentation; and (iii) contribution by any seller of
Registrable Securities shall be limited in amount to the net amount of proceeds
received by such seller from the sale of such Registrable Securities.

     8. REPORTS UNDER THE 1934 ACT.

     With a view to making available to the Investors the benefits of Rule 144
promulgated under the 1933 Act or any other similar rule or regulation of the
SEC that may at any time permit the investors to sell securities of the Company
to the public without registration ("RULE 144"), the Company agrees, to:

          a. make and keep public information available, as those terms are
     understood and defined in Rule 144;

          b. file with the SEC in a timely manner all reports and other
     documents required of the Company under the 1933 Act and the 1934 Act so
     long as the Company remains subject to such requirements (it being
     understood that nothing herein shall limit the Company's obligations under
     Section 4(c) of the Securities Purchase Agreement) and the filing of such
     reports and other documents is required for the applicable provisions of
     Rule 144; and

                                      G-12
<PAGE>   251

          c. furnish to each Investor so long as such Investor owns Registrable
     Securities, promptly upon request, (i) a written statement by the Company
     that it has complied with the reporting requirements of Rule 144, the 1933
     Act and the 1934 Act, (ii) a copy of the most recent annual or quarterly
     report of the Company and such other reports and documents so filed by the
     Company, and (iii) such other information as may be reasonably requested to
     permit the investors to sell such securities pursuant to Rule 144 without
     registration.

     9. ASSIGNMENT OF REGISTRATION RIGHTS.

     The rights to have the Company register Registrable Securities pursuant to
this Agreement shall be automatically assignable by the Investors to any
transferee of all or any portion of Registrable Securities if: (i) the Investor
agrees in writing with the transferee or assignee to assign such rights, and a
copy of such agreement is furnished to the Company within a reasonable time
after such assignment; (ii) the Company is, within a reasonable time after such
transfer or assignment, furnished with written notice of (a) the name and
address of such transferee or assignee, and (b) the securities with respect to
which such registration rights are being transferred or assigned; (iii)
immediately following such transfer or assignment the further disposition of
such securities by the transferee or assignee is restricted under the 1933 Act
and applicable state securities laws; (iv) at or before the time the Company
receives the written notice contemplated by clause (ii) of this sentence the
transferee or assignee agrees in writing with the Company to be bound by all of
the provisions contained herein; (v) such transfer shall have been made in
accordance with the applicable requirements of the Securities Purchase
Agreement; (vi) such transferee shall be an "ACCREDITED INVESTOR" as that term
is defined in Rule 501 of Regulation D promulgated under the 1933 Act; and (vii)
in the event the assignment occurs subsequent to the date of effectiveness of
the Registration Statement required to be filed pursuant to Section 2(a), the
transferee agrees to pay all reasonable expenses of amending or supplementing
such Registration Statement to reflect such assignment.

     10. AMENDMENT OF REGISTRATION RIGHTS.

     Provisions of this Agreement may be amended and the observance thereof may
be waived (either generally or in a particular instance and either retroactively
or prospectively), only with the written consent of the Company and Investors
who hold two-thirds of the Registrable Securities. Any amendment or waiver
effected in accordance with this Section 10 shall be binding upon each Investor
and the Company.

     11. MISCELLANEOUS.

          a. A person or entity is deemed to be a holder of Registrable
     Securities whenever such person or entity owns of record such Registrable
     Securities. If the Company receives conflicting instructions, notices or
     elections from two or more persons or entities with respect to the same
     Registrable Securities, the Company shall act upon the basis of
     instructions, notice or election received from the registered owner of such
     Registrable Securities.

          b. Any notices consents, waivers or other communications required or
     permitted to be given under the terms of this Agreement must be in writing

                         REGISTRATION RIGHTS AGREEMENT

     REGISTRATION RIGHTS AGREEMENT (this "AGREEMENT"), dated as of June 30,

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Company and the Buyer hereby
agree as follows:

     1. DEFINITIONS.

     As used in this Agreement, the following terms shall have the following
meanings:

          a. "INVESTOR" means the Buyer and any transferee or assignee thereof

          b. "PERSON" means a corporation, a limited liability company, an
     association, a partnership, an organization, a business, an individual, a
     governmental or political subdivision thereof or a governmental agency.

          c. "REGISTER," "REGISTERED," and "REGISTRATION" refer to a
     registration effected by preparing and filing one or more Registration
     Statements in compliance with the 1933 Act and pursuant to Rule 415 under

<PAGE>   256

          e. "REGISTRATION STATEMENT" means a registration statement of the
     Company filed under the 1933 Act.

     Capitalized terms used herein and not otherwise defined herein shall have
the respective meanings set for the in the Securities Purchase Agreement.

     2. REGISTRATION.

          a. PIGGY-BACK REGISTRATIONS.  If at any time prior to the expiration
     of the Registration Period (as hereinafter defined) the Company proposes to
     file with the SEC a Registration Statement relating to an offering for its
     own account or the account of others under the 1933 Act of any of its
     securities (other than pursuant to an initial public offering of any
     securities of the Company or a filing on Form S-4 or Form S-8 or their then
     equivalents relating to securities to be issued solely in connection with
     any acquisition of any entity or business or equity securities issuable in
     connection with stock option or other employee benefit plans) the Company
     shall promptly send to each Investor who is entitled to registration rights
     under this Section 2(c) written notice of the Company's intention to file a
     Registration Statement and of such Investor's rights under this Section
     2(c) and, if within twenty (20) days after receipt of such notice, such
     Investor shall so request in writing, the Company shall include in such
     Registration Statement all or any part of the Registrable Securities such
     Investor requests to be registered, subject to the priorities set forth in
     Section 2(d) below. No right to registration of Registrable Securities
     under this Section 2(c) shall be construed to limit any registration
     required under Section 2(a). The obligations of the Company under this
     Section 2(c) may be waived by Investors holding a majority of the
     Registrable Securities. If an offering in connection with which an Investor
     is entitled to registration under this Section 2(c) is an underwritten
     offering, then each Investor whose Registrable Securities are included in
     such Registration Statement shall, unless otherwise agreed by the Company,
     offer and sell such Registrable Securities in an underwritten offering
     using the same underwriter or underwriters and, subject to the provisions
     of this Agreement, on the same terms and conditions as other shares of
     Common Stock included in such underwritten offering. As used herein,
     "REGISTRATION PERIOD" shall mean the earlier of (i) the date as of which
     the Investors may sell all of the Registrable Securities without
     restriction pursuant to Rule 144(k) promulgated under the 1933 Act (or
     successor thereto) or (ii) the date on which (A) the Investors shall have
     sold all the Registrable Securities.

          b. PRIORITY IN PIGGY-BACK REGISTRATION RIGHTS IN CONNECTION WITH
     REGISTRATIONS OR COMPANY ACCOUNT.  If the registration referred to in
     Section 2(c) is to be an underwritten public offering for the account of
     the Company and the managing underwriter(s) advise the Company in writing,
     that in their reasonable good faith opinion, marketing or other factors
     dictate that a limitation on the number of shares of Common Stock which may
     be included in the Registration Statement is necessary to facilitate and
     not adversely affect the proposed offering, then the Company shall include
     in such registration: (1) first, all securities the Company proposes to
     sell for its own account, (2) second, up to the full number of securities
     proposed to be registered for the account of the holders of securities
     entitled to inclusion of their securities in the Registration Statement by
     reason of demand registration rights, and (3) third, the securities
     requested to be registered by the Investors and other holders of securities
     entitled to participate in the registration, drawn from them pro rata based
     on the number each has requested to be included in such registration.

<PAGE>   257

     3. RELATED OBLIGATIONS.

     Whenever an Investor has requested that any Registrable Securities be
registered pursuant to Section 2(c) or at such time as the Company is obligated
to file a Registration Statement with the SEC pursuant to Section 2(a), the
Company will use its best efforts to effect the registration of the Registrable
Securities in accordance with the intended method of disposition thereof and,
pursuant thereto, the Company shall have the following obligations:

          a. The Company shall furnish to each Investor whose Registrable
     Securities are included in the Registration Statement(s) and its legal
     counsel without charge (i) promptly after the same is prepared and filed
     with the SEC at least one copy of the Registration Statement and any
     amendment thereto, including financial statements and schedules, all
     documents incorporated therein by reference and all exhibits, the
     prospectus(es) included in such Registration Statement(s) (including each
     preliminary prospectus ) and, with regards to the Registration Statement,
     any correspondence by or on behalf of the Company to the SEC or the staff
     of the SEC and any correspondence from the SEC or the staff of the SEC to
     the Company or its representatives, (ii) upon the effectiveness of any
     Registration Statement, ten (10) copies of the prospectus included in such
     Registration Statement and all amendments and supplements thereto (or such
     other number of copies as such Investor may reasonably request) and (iii)
     such other documents, including any preliminary prospectus, as such
     Investor may reasonably request in order to facilitate the disposition of
     the Registrable Securities owned by such Investor.

          b. The Company shall use reasonable efforts to (i) register and
     qualify the Registrable Securities covered by the Registration Statement(s)
     under the securities or "blue sky" laws of such jurisdictions in the United
     States as any Investor reasonably requests, (ii) prepare and file in those
     jurisdictions, such amendments (including post-effective amendments) and
     supplements to such registrations and qualifications as may be necessary to
     maintain the effectiveness thereof during the Registration Period, (iii)
     take such other actions as may be necessary to maintain such registrations
     and qualifications in effect at all times during the Registration Period,
     and (iv) take all other actions reasonably necessary or advisable to
     quality the Registrable Securities for sale in such jurisdictions;
     provided, however, that the Company shall not be required in connection
     therewith or as a condition thereto to (a) qualify to do business in any
     jurisdiction where it would not otherwise be required to qualify but for
     this Section 3(d), (b) subject itself to general taxation in any such
     jurisdiction, or (c) file a general consent to service of process in any
     such jurisdiction. The Company shall promptly notify each Investor who
     holds Registrable Securities of the receipt by the Company of any
     notification with respect to the suspension of the registration or
     qualification of any of the Registrable Securities for sale under the
     securities or "blue sky" laws of any jurisdiction in the United States or
     its receipt of actual notice of the initiation or threatening of any
     proceeding for such purpose.

          c. In the event Investors who hold a majority of the Registrable
     Securities being offered in the offering select underwriters for the
     offering, the Company shall enter into and perform its obligations under an
     underwriting agreement, in usual and customary form, including, without
     limitation, customary indemnification and contribution obligations, with
     the underwriters of such offering. The cost of such underwriters shall be
     borne by the Investors.

<PAGE>   258

          d. As promptly as practicable after becoming aware of such event, the
     Company shall notify each Investor in writing of the happening of any
     event, of which the Company has knowledge, as a result of which the
     prospectus included in a Registration Statement, as then in effect,
     includes an untrue statement of a material fact or omission 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, and promptly prepare a supplement or amendment to the
     Registration Statement to correct such untrue statement or omission, and
     deliver ten (10) copies of such supplement or amendment to each Investor
     (or such other number of copies as such Investor may reasonably request).
     The Company shall also promptly notify each Investor in writing (i) when a
     prospectus or any prospectus supplement or post-effective amendment has
     been filed, and when a Registration Statement or any post-effective
     amendment has become effective (notification of such effectiveness shall be
     delivered to each Investor by facsimile on the same day of such
     effectiveness and by overnight mail) (ii) of any request by the SEC for
     amendments or supplements to a Registration Statement or related prospectus
     or related information, (iii) of the Company's reasonable determination
     that a post-effective amendment to a Registration Statement would be
     appropriate.

          e. The Company shall use its best efforts to prevent the issuance of
     any stop order or other suspension of effectiveness of a Registration
     Statement, or the suspension of the qualification of any of the Registrable
     Securities for sale in any jurisdiction and, if such an order or suspension
     is issued, to obtain the withdrawal of such order or suspension at the
     earliest possible moment and to notify each Investor who holds Registrable
     Securities being sold (and, in the event of an underwritten offering, the
     managing underwriters) of the issuance of such order and the resolution
     thereof or its receipt of actual notice of the initiation or threat of any
     proceeding for such purpose.

          f. The Company shall permit each Investor at such Investors expense a
     single firm of counsel or such other counsel as thereafter designated as
     selling stockholders' counsel by the Investors who hold a majority of the
     Registrable Securities being sold, to review and comment upon the
     Registration Statement(s) and all amendments and supplements thereto at
     least seven (7) days prior to their filing with the SEC.

          g. At the request of the Investors who hold a majority of the
     Registrable Securities being sold, the Company shall furnish, on the date
     that Registrable Securities are delivered to an underwriter, if any, for
     sale in connection with the Registration Statement (i) if required by an
     underwriter, a letter, dated such date, from the Company's independent
     certified public accountants in form and substance as is customarily given
     by independent certified public accountants to underwriters in an
     underwritten public offering, addressed to the underwriters, and (ii) an
     opinion, dated as of such date, of counsel representing the Company for
     purposes of such Registration Statement, in form, scope and substance as is
     customarily given in an underwritten public offering, addressed to the
     underwriters and the Investors.

          h. The Company shall make available for inspection by (i) any
     Investor, (ii) any underwriter participating in any disposition pursuant to
     a Registration Statement, (iii) one firm of attorneys and one firm of
     accountants or other agents retained by the Investors, and (iv) one firm of
     attorneys retained by all such underwriters (collectively, the
     "INSPECTORS") all pertinent financial and other records, and pertinent
     corporate documents and properties of the Company (collectively, the
     "RECORDS"), as

                                      G-20
<PAGE>   259

     shall be reasonably deemed necessary by each Inspector to enable each
     Inspector to exercise its due diligence responsibility, and cause the
     Company's officers, directors and employees to supply all information which
     any Inspector may reasonably request for purposes of such due diligence
     provided, however, that each Inspector shall hold in strict confidence and
     shall not make any disclosure (except to an Investor) or use of any Record
     or other information which the Company determines in good faith to be
     confidential, and of which determination the Inspectors are so notified,
     unless (a) the disclosure of such Records is necessary to avoid or correct
     a misstatement or omission in any Registration Statement or is otherwise
     required under the 1933 Act, (b) the release of such Records is ordered
     pursuant to a final, non-appealable subpoena or order from a court or
     government body of competent jurisdiction, or (c) the information in such
     Records has been made generally available to the public other than by
     disclosure in violation of this or any other agreement. Each Investor
     agrees that it shall, upon learning that disclosure of such Records is
     sought in or by a court or governmental body of competent jurisdiction or
     through other means, give prompt notice to the Company and allow the
     Company, at its expense, to undertake appropriate action to prevent
     disclosure of, or to obtain a protective order for, the Records deemed
     confidential. All fees, costs and expenses of the foregoing shall be borne
     by the Investors.

          i. The Company shall hold in confidence and not make any disclosure of
     information concerning an Investor provided to the Company unless (i)
     disclosure of such information is necessary to comply with federal or state
     securities laws, (ii) the disclosure of such information is necessary to
     avoid or correct a misstatement or omission in any Registration Statement,
     (iii) the release of such information is ordered pursuant to a subpoena or
     other final, non-appealable order from a court or governmental body of
     competent jurisdiction, or (iv) such information has been made generally
     available to the public other than by disclosure in violation of this or
     any other agreement. The Company agrees that it shall, upon learning that
     disclosure of such information concerning an Investor is sought in or by a
     court or governmental body of competent jurisdiction or through other
     means, give prompt written notice to such Investor and allow such Investor,
     at the Investor's expense, to undertake appropriate action to prevent
     disclosure of, or to obtain a protective order for, such information.

          j. The Company shall use reasonable efforts either to (i) cause all
     the Registrable Securities covered by a Registration Statement to be listed
     on each national securities exchange on which securities of the same class
     or series issued by the Company are then listed, if any, if the listing of
     such Registrable Securities is then permitted under the rules of such
     exchange, (ii) to secure designation and quotation of all the Registrable
     Securities covered by the Registration Statement on the Nasdaq National
     Market System, (iii) if, despite the Company's reasonable efforts to
     satisfy the preceding clause (i) or (ii), the Company is unsuccessful in
     satisfying the preceding clause (i) or (ii) to secure the inclusion for
     quotation on the Nasdaq SmallCap Market for such Registrable Securities or,
     (iv) if, despite the Company's reasonable efforts to satisfy the preceding
     clause (iii), the Company is unsuccessful in satisfying the preceding
     clause (iii), to secure the inclusion for quotation on the over-the-counter
     market for such Registrable Securities, and, without limiting the
     generality of the foregoing, in the case of clause (iii) or (iv), to
     arrange for at least two market makers to register with the National
     Association of Securities Dealers, Inc. ("NASD") as such with respect to
     such Registrable Securities. The

                                      G-21
<PAGE>   260

     Company shall pay all fees and expenses in connection with satisfying its
     obligation under this Section 3(j).

          k. The Company shall cooperate with the Investors who hold Registrable
     Securities being offered and, to the extent applicable, any managing
     underwriter or underwriters, to facilitate the timely preparation and
     delivery of certificates (not bearing any restrictive legend) representing
     the Registrable Securities to be offered pursuant to a Registration
     Statement and enable such certificates to be in such denominations or
     amounts, as the case may be, as the managing underwriter or underwriters,
     if any, or, if there is no managing underwriter or underwriters, the
     Investors may reasonably request and registered in such names as the
     managing underwriter or underwriters, if any, or the Investors may request.
     Not later than the date on which any Registration Statement registering the
     resale of Registrable Securities is declared effective, the Company shall
     deliver to its transfer agent instructions, accompanied by any reasonably
     required opinion of counsel, that permit sales of unlegended securities in
     a timely fashion that complies with then mandated securities settlement
     procedures for regular way market transactions.

          l. The Company shall take all other reasonable actions necessary to
     expedite and facilitate disposition by the Investors of Registrable
     Securities pursuant to a Registration Statement.

          m. The Company shall provide a transfer agent and registrar of all
     such Registrable Securities not later than the effective date of such
     Registration Statement.

          n. If reasonably requested by the managing underwriters, the Company
     shall immediately incorporate in a prospectus supplement or post-effective
     amendment such information as the managing underwriters and the Investors
     agree should be included therein relating to the sale and distribution of
     Registrable Securities, including, without limitation, information with
     respect to the number of Registrable Securities being sold to such
     underwriters, the purchase price being paid therefor by such underwriters
     and with respect to any other terms of the underwritten (or best efforts
     underwritten) offering of the Registrable Securities to be sold in such
     offering; make all required filings of such prospectus supplement or
     post-effective amendment as soon as notified of the matters to be
     incorporated in such prospectus supplement or post-effective amendment; and
     supplement or make amendments to any Registration Statement if requested by
     a shareholder or any underwriter of such Registrable Securities. The costs
     of preparation and filing of any such post-effective amendments and
     supplements shall be borne by the Investors.

          o. The Company shall use its best efforts to cause the Registrable
     Securities covered by the applicable Registration Statement to be
     registered with or approved by such other governmental agencies or
     authorities as may be necessary to consummate the disposition of such
     Registrable Securities.

          p. The Company shall otherwise use its best efforts to comply with all
     applicable rules and regulations of the SEC in connection with any
     registration hereunder.

     4. OBLIGATIONS OF THE INVESTORS.

          a. At least seven (7) days prior to the first anticipated filing date
     of the Registration Statement, the Company shall notify each Investor in
     writing of the information the Company requires from each such Investor if
     such Investor elects to

                                      G-22
<PAGE>   261

     have any of such Investor's Registrable Securities included in the
     Registration Statement. It shall be a condition precedent to the
     obligations of the Company to complete the registration pursuant to this
     Agreement with respect to the Registrable Securities of a particular
     Investor that such Investor shall furnish to the Company such information
     regarding itself, the Registrable Securities held by it and the intended
     method of disposition of the Registrable Securities held by it as shall be
     reasonably required to effect the registration of such Registrable
     Securities and shall execute such documents in connection with such
     registration as the Company may reasonably request.

          b. Each Investor by such Investor's acceptance of the Registrable
     Securities agrees to cooperate with the Company as reasonably requested by
     the Company in connection with the preparation and filing of the
     Registration Statement(s) hereunder, unless such Investor has notified the
     Company in writing of such Investor's election to exclude all of such
     Investor's Registrable Securities from the Registration Statement.

          c. Each Investor agrees to enter into and perform such Investor's
     obligations under an underwriting agreement, in usual and customary form,
     including, without limitation, customary indemnification and contribution
     obligations, with the managing underwriter of such offering and take such
     other actions as are reasonably required in order to expedite or facilitate
     the disposition of the Registrable Securities, unless such Investor
     notifies the Company in writing of such Investor's election to exclude all
     of such Investor's Registrable Securities from the Registration
     Statement(s). Each Investor agrees to enter into any contractual lock-up
     agreements with respect to the Common Stock or other securities held by
     each Investor in connection with an underwritten public offering of the
     Company's common stock or other securities.

          d. Each Investor agrees that, upon receipt of any notice from the
     Company of the happening of any event of the kind described in Section 3(h)
     or the first sentence of 3(d), such Investor will immediately discontinue
     disposition of Registrable Securities pursuant to the Registration
     Statement(s) covering such Registrable Securities until such Investor's
     receipt of the copies of the supplemented or amended prospectus
     contemplated by Section 3(e) or the first sentence of 3(d) and, if so
     directed by the Company, such Investor shall deliver to the Company (at the
     expense of the Company) or destroy all copies in such Investor's
     possession, of the prospectus covering such Registrable Securities current
     at the time of receipt of such notice.

          e. No Investor may participate in any underwritten registration
     hereunder unless such Investor (i) agrees to sell such Investor's
     Registrable Securities on the basis provided in any underwriting
     arrangements approved by the Investors entitled hereunder to approve such
     arrangements, (ii) completes and executes all questionnaires, powers of
     attorney, indemnities, underwriting agreements and other documents
     reasonably required under the terms of such underwriting arrangements, and
     (iii) agrees to pay its pro rata share of all underwriting discounts and
     commissions.

     5. EXPENSES OF REGISTRATION.

     All reasonable expenses, other than underwriting discounts and commissions,
incurred in connection with registrations, filings or qualifications pursuant to
Sections 2 and 3, including, without limitation, all registration, listing and
qualifications fees, printers and accounting fees, and fees and disbursements of
counsel for the Company shall be borne by the Company except as otherwise
specifically proved herein.

     6. INDEMNIFICATION

     In the event any Registrable Securities are included in a Registration
Statement under this Agreement:

          a. To the fullest extent permitted by law, the Company will, and
     hereby does, indemnify, hold harmless and defend each Investor who holds
     such Registrable Securities, the directors, officers, partners, employees,
     agents and each Person, if any, who controls any Investor within the
     meaning of the 1933 Act or the Securities Exchange Act of 1934, as amended
     (the "1934 ACT"), and any underwriter (as defined in the 1933 Act) for the
     Investors, and the directors and officers of, and each Person, if any, who
     controls, any such underwriter within the meaning of the 1933 Act or the
     1934 Act (each, an "INDEMNIFIED PERSON"), against any losses, claims,
     damages, liabilities, judgments, fines, penalties, charges, costs,
     attorneys' fees, amounts paid in settlement or expenses, joint or several,
     (collectively, "CLAIMS") incurred in investigating, preparing or defending
     any action, claim, suit, inquiry, proceeding, investigation or appeal taken
     from the foregoing by or before any court or governmental, administrative
     or other regulatory agency, body or the SEC, whether pending or threatened,
     whether or not an indemnified party is or may be a party thereto
     ("INDEMNIFIED DAMAGES"), to which any of them may become subject insofar as
     such Claims (or actions or proceedings, whether commenced or threatened, in
     respect thereof) arise out of or are based upon: (i) any untrue statement
     or alleged untrue statement of a material fact in a Registration Statement
     or any post-effective amendment thereto or in any filing made in connection
     with the qualification of the offering under the securities or other "blue
     sky" laws of any jurisdiction in which Registrable Securities are offered
     ("BLUE SKY FILING"), or the omission or alleged omission to state a
     material fact required to be stated therein or necessary to make the
     statements therein, in light of the circumstances under which the
     statements therein were made, not misleading, (ii) any untrue statement or
     alleged untrue statement of a material fact contained in any preliminary
     prospectus if used prior to the effective date of such Registration
     Statement, or contained in the final prospectus (as amended or
     supplemented, if the Company files any amendment thereof or supplement
     thereto with the SEC) or the omission or alleged omission to state therein
     any material fact necessary to make the statements made therein, in light
     of the circumstances under which the statements therein were made, not
     misleading, or (iii) any violation or alleged violation by the Company of
     the 1933 Act, the 1934 Act, any other law, including, without limitation,
     any state securities law, or any rule or regulation thereunder relating to
     the offer or sale of the Registrable Securities pursuant to a Registration
     Statement (the matters in the foregoing clauses (i) through (iii) being,
     collectively, "VIOLATIONS"). Subject to the restrictions set forth in
     Section 6(d) with respect to the number of legal counsel, the Company shall
     reimburse the Investors and each such underwriter or controlling person,
     promptly as such expenses are incurred and are due and payable, for any
     legal fees or other reasonable expenses incurred by them in connection with
     investigating or defending any such Claim. Notwithstanding anything to the
     contrary contained herein, the indemnification agreement contained in this
     Section 6(a): (i) shall not apply to a Claim arising out of or based upon a
     Violation which occurs in reliance upon and in conformity with information
     furnished in writing to the Company by any Indemnified Person or
     underwriter for such Indemnified Person expressly for use in connection
     with the preparation of the Registration Statement or any such amendment
     thereof or supplement thereto, if such prospectus was timely made available
     by the Company

                                      G-24
<PAGE>   263

     pursuant to Section 3(c); (ii) with respect to any preliminary prospectus,
     shall not inure to the benefit of any such person from whom the person
     asserting any such Claim purchased the Registrable Securities that are the
     subject thereof (or to the benefit of any person controlling such person)
     if the untrue statement or mission of material fact contained in the
     preliminary prospectus was corrected in the prospectus, as then amended or
     supplemented, if such prospectus was timely made available by the Company
     pursuant to Section 3(c), and the Indemnified Person was promptly advised
     in writing not to use the incorrect prospectus prior to the use giving rise
     to a violation and such Indemnified Person, notwithstanding such advice,
     used it; (iii) shall not be available to the extent such Claim is based on
     a failure of the Investor to deliver or to cause to be delivered the
     prospectus made available by the Company (i) and (iv) shall not apply to
     amounts paid in settlement of any Claim if such settlement is effected
     without the prior written consent of the Company, which consent shall not
     be unreasonably withheld. Such indemnity shall remain in full force and
     effect regardless of any investigation made by or on behalf of the
     Indemnified Person and shall survive the transfer of the Registrable
     Securities by the Investors pursuant to Section 9 for a period of three (3)
     years from the Filing Deadline.

          b. In connection with any Registration Statement in which an Investor
     is participating, each such Investor agrees to severally and not jointly
     indemnify, hold harmless and defend, to the same extent and in the same
     manner as is set forth in Section 6(a), the Company, each of its directors,
     each of its officers who signs the Registration Statement, each Person, if
     any, who controls the Company within the meaning of the 1933 Act or the
     1934 Act (collectively and together with an Indemnified Person, an
     "INDEMNIFIED PARTY"), against any Claim or Indemnified Damages to which any
     of them may become subject, under the 1933 Act, the 1934 Act or otherwise,
     insofar as such Claim or Indemnified Damages arise out of or are based upon
     any Violation, in each case to the extent, and only to the extent, that
     such Violation occurs in reliance upon and in conformity with written
     information furnished to the Company by such Investor expressly for use in
     connection with such Registration Statement; and, subject to Section 6(d),
     such Investor will reimburse any legal or other expenses reasonably
     incurred by them in connection with investigating or defending any such
     Claim; provided, however, that the indemnity agreement contained in this
     Section 6(b) and Section 7 shall not apply to amounts paid in settlement of
     any Claim if such settlement is effected without the prior written consent
     of such Investor, which consent shall not be unreasonably withheld;
     provided, further, however, that the Investor shall be liable under this
     Section 6(b) for only that amount of a Claim or Indemnified Damages as does
     not exceed the net proceeds to such Investor as a result of the sale of
     Registrable Securities pursuant to such Registration Statement. Such
     indemnity shall remain in full force and effect regardless of any
     investigation made by or on behalf of such Indemnified Party and shall
     survive the transfer of the Registrable Securities by the Investors
     pursuant to Section 9. Notwithstanding anything to the contrary contained
     herein, the indemnification agreement contained in this Section 6(b) with
     respect to any preliminary prospectus shall not inure to the benefit of any
     Indemnified Party if the untrue statement or omission of material fact
     contained in the preliminary prospectus was corrected on a timely basis in
     the prospectus, as then amended or supplemented.

          c. The Company shall be entitled to receive indemnities from
     underwriters, selling brokers, dealer managers and similar securities
     industry professionals participating in any distribution, to the same
     extent as provided above, with respect to

                                      G-25
<PAGE>   264

     information such persons so furnished in writing expressly for inclusion in
     the Registration Statement.

          d. Promptly after receipt by an Indemnified Person or Indemnified
     Party under this Section 6 of notice of the commencement of any action or
     proceeding (including any governmental action or proceeding) involving a
     Claim such Indemnified Person or Indemnified Party shall, if a Claim in
     respect thereof is to be made against any indemnifying party under this
     Section 6, deliver to the indemnifying party a written notice of the
     commencement thereof, and the indemnifying party shall have the right to
     participate in, and, to the extent the indemnifying party so desires,
     jointly with any other indemnifying party similarly noticed, to assume
     control of the defense thereof with counsel mutually satisfactory to the
     indemnifying party and the Indemnified Person or the Indemnified Party, as
     the case may be; provided, however, that an Indemnified Person or
     Indemnified Party shall have the right to retain its own counsel with the
     fees and expenses to be paid by the indemnifying party, if, in the
     reasonable opinion of counsel retained by the indemnifying party, the
     representation by such counsel of the Indemnified Person or Indemnified
     Party and the indemnifying party would be inappropriate due to actual or
     potential differing interests between such Indemnified Person or
     Indemnified Party and any other party represented by such counsel in such
     proceeding. The Company shall pay reasonable fees for only one separate
     legal counsel for the Investors, and such legal counsel shall be selected
     by the Investors holding a majority in interest of the Registrable
     Securities included in the Registration Statement to which the Claim
     relates. The Indemnified Party or Indemnified Person shall cooperate fully
     with the indemnifying party in connection with any negotiation or defense
     of any such action or claim by the indemnifying party and shall furnish to
     the indemnifying party all information reasonably available to the
     Indemnified Party or Indemnified Person which relates to such action or
     claim. The indemnifying party shall keep the Indemnified Party or
     Indemnified Person fully apprised at all times as to the status of the
     defense or any settlement negotiations with respect thereto. No
     indemnifying party shall be liable for any settlement of any action, claim
     or proceeding effected without its written consent, provided, however, that
     the indemnifying party shall not unreasonably withhold, delay or condition
     its consent. No indemnifying party shall, without the consent of the
     Indemnified Party or Indemnified Person, consent to entry of any judgment
     or enter into any settlement or other compromise which does not include as
     an unconditional term thereof the giving by the claimant or plaintiff to
     such Indemnified Party or Indemnified Person of a release from all
     liability in respect to such claim or litigation. Following indemnification
     as provided for hereunder, the indemnifying party shall be subrogated to
     all rights of the Indemnified Party or Indemnified Person with respect to
     all third parties, firms or corporations relating to the matter for which
     indemnification has been made. The failure to deliver written notice to the
     indemnifying party within a reasonable time of the commencement of any such
     action shall not relieve such indemnifying party of any liability to the
     Indemnified Person or Indemnified Party under this Section 6, except to the
     extent that the indemnifying party is prejudiced in its ability to defend
     such action.

          e. The indemnification required by this Section 6 shall be made by
     periodic payments of the amount thereof during the course of the
     investigation or defense, as and when bills are received or Indemnified
     Damages are incurred.

                                      G-26
<PAGE>   265

          f. The indemnity agreements contained herein shall be in addition to
     (i) any cause of action or similar right of the Indemnified Party or
     Indemnified Person against the indemnifying party or others, and (ii) any
     liabilities the indemnifying party may be subject to pursuant to the law.

     7. CONTRIBUTION.

     To the extent any indemnification by an indemnifying party is prohibited or
limited by law, the indemnifying party agrees to make the maximum contribution
with respect to any amounts for which it would otherwise be liable under Section
6 to the fullest extent permitted by law; provided, however, that: (i) no
contribution shall be made under circumstances where the maker would not have
been liable for indemnification under the fault standards set forth in Section 6
and (ii) no seller of Registrable Securities guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution from any seller of Registrable Securities who was not
guilty of fraudulent misrepresentation.

     8. REPORTS UNDER THE 1934 ACT.

     With a view to making available to the Investors the benefits of Rule 144
promulgated under the 1933 Act or any other similar rule or regulation of the
SEC that may at any time permit the investors to sell securities of the Company
to the public without registration ("RULE 144"), the Company agrees, once the
Company becomes a reporting company under the 1934 Act upon the effective date
of its Form 10 to be filed with the SEC, to:

          a. make and keep public information available, as those terms are
     understood and defined in Rule 144;

          b. file with the SEC in a timely manner all reports and other
     documents required of the Company under the 1933 Act and the 1934 Act so
     long as the Company remains subject to such requirements and the filing of
     such reports and other documents is required for the applicable provisions
     of Rule 144; and

          c. furnish to each Investor so long as such Investor owns Registrable
     Securities, promptly upon request, (i) a written statement by the Company
     that it has complied with the reporting requirements of Rule 144, the 1933
     Act and the 1934 Act, (ii) a copy of the most recent annual or quarterly
     report of the Company and such other reports and documents so filed by the
     Company, and (iii) such other information as may be reasonably requested to
     permit the investors to sell such securities pursuant to Rule 144 without
     registration.

     9. ASSIGNMENT OF REGISTRATION RIGHTS.

     The rights to have the Company register Registrable Securities pursuant to
this Agreement shall be automatically assignable by the Investors to any
transferee of all or any portion of Registrable Securities if: (i) the Investor
agrees in writing with the transferee or assignee to assign such rights, and a
copy of such agreement is furnished to the Company within a reasonable time
after such assignment; (ii) the Company is, within a reasonable time after such
transfer or assignment, furnished with written notice of (a) the name and
address of such transferee or assignee, and (b) the securities with respect to
which such registration rights are being transferred or assigned; (iii)
immediately following such transfer or assignment the further disposition of
such securities by the transferee or assignee is restricted under the 1933 Act
and applicable state

                                      G-27
<PAGE>   266

securities laws; (iv) at or before the time the Company receives the written
notice contemplated by clause (ii) of this sentence the transferee or assignee
agrees in writing with the Company to be bound by all of the provisions
contained herein; (v) such transfer shall have been made in accordance with the
applicable requirements of the Securities Purchase Agreement; (vi) such
transferee shall be an "ACCREDITED INVESTOR" as that term is defined in Rule 501
of Regulation D promulgated under the 1933 Act; and (vii) in the event the
assignment occurs subsequent to the date of effectiveness of the Registration
Statement required to be filed pursuant to Section 2(a), the transferee agrees
to pay all reasonable expenses of amending or supplementing such Registration
Statement to reflect such assignment.

     10. AMENDMENT OF REGISTRATION RIGHTS.

     Provisions of this Agreement may be amended and the observance thereof may
be waived (either generally or in a particular instance and either retroactively
or prospectively), only with the written consent of the Company and Investors
who hold two-thirds of the Registrable Securities. Any amendment or waiver
effected in accordance with this Section 10 shall be binding upon each Investor
and the Company.

     11. MISCELLANEOUS.

          a. A person or entity is deemed to be a holder of Registrable
     Securities whenever such person or entity owns of record such Registrable
     Securities. If the Company receives conflicting instructions, notices or
     elections from two or more persons or entities with respect to the same
     Registrable Securities, the Company shall act upon the basis of
     instructions, notice or election received from the registered owner of such
     Registrable Securities.

                               WARRANT AGREEMENT

     WARRANT AGREEMENT dated as of June 30, 1999, between Allergy
Superstore.com, Inc., a Delaware corporation (the "COMPANY"), and Jackson LLC, a
Cayman Island limited liability company (hereinafter referred to as "INVESTOR").

                              W I T N E S S E T H:

     WHEREAS, Investor has participated as an Investor in connection with the
Company's offering (the "OFFERING") of up to $15,000,000 in aggregate amount of
common stock, par value $0.001 per share (the "COMMON STOCK") for an aggregate
purchase price of $15,000,000; and

     WHEREAS, the Warrants issued pursuant to this Agreement are being issued by
the Company to Investor and/or its designees, in consideration for, and as part
of the investment by Investor in connection with the Offering;

     NOW, THEREFORE, in consideration of the premises, the agreements herein set
forth and other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties hereto agree as follows:

1. GRANT.

     Investor and/or its designees are hereby granted the right to purchase, at
any time from the date of issuance of the aforementioned Preferred Stock until
5:00 P.M., Eastern Standard Time, on June 29, 2004 (the "WARRANT EXERCISE
TERM"), 100,000 Shares at an exercise price (subject to adjustment as provided
in Article 7 hereof) of $5.126 per share (the "INITIAL EXERCISE PRICE").

2. WARRANT CERTIFICATES.

     The warrant certificates (the "WARRANT CERTIFICATES") delivered and to be
delivered pursuant to this Agreement shall be in the form set forth as Exhibit
A, attached hereto and made a part hereof, with such appropriate insertions,
omissions, substitutions and other variations as required or permitted by this
Agreement.

3. EXERCISE OF WARRANTS.

     3.1 CASH EXERCISE.  The Exercise Price may be paid in cash or by check to
the order of the Company, or any combination of cash or check, subject to
adjustment as provided in Article 7 hereof. Upon surrender of the Warrant
Certificate with the annexed Form of Election to Purchase duly executed,
together with payment of the Exercise Price (as hereinafter defined) for the
Shares purchased, at the Company's executive offices currently located at 4405
International Blvd., Norcross Georgia 30093, the registered holder of a Warrant
Certificate ("HOLDER" or "HOLDERS") shall be entitled to receive a certificate
or certificates for the Shares so purchased. The purchase rights represented by
each Warrant Certificate are exercisable at the option of the Holder hereof, in
whole or in part (but not as to fractional shares of the Common Stock). In the
case of the purchase of less than all

                                       H-1
<PAGE>   271

the Shares purchasable under any Warrant Certificate, the Company shall cancel
said Warrant Certificate upon the surrender thereof and shall execute and
deliver a new Warrant Certificate of like tenor for the balance of the Shares
purchasable thereunder.

     3.2 CASHLESS EXERCISE.  At any time during the Warrant Exercise Term, the
Holder may, at its option, exchange this Warrant, in whole or in part (a
"WARRANT EXCHANGE"), into the number of Shares determined in accordance with
this Section 3.2, by surrendering this Warrant at the principal office of the
company or at the office of its transfer agent, accompanied by a notice stating
such Holder's intent to effect such exchange, the number of Shares to be
exchanged and the date on which the Holder requests that such Warrant Exchange
occur (the "NOTICE OF EXCHANGE"). The Warrant Exchange shall take place on the
date specified in the Notice of Exchange or, if later, the date the Notice of
Exchange is received by the Company (the "EXCHANGE DATE"). Certificates for the
Shares issuable upon such Warrant Exchange and, if applicable, a new warrant of
like tenor evidencing the balance of the Shares remaining subject to this
Warrant, shall be issued as of the Exchange Date and delivered to the Holder
within seven (7) business days following the Exchange Date. In connection with
any Warrant Exchange, this Warrant shall represent the right to subscribe for
and acquire the number of Shares (rounded to the next highest integer) equal to
(i) the number of Shares specified by the Holder in its Notice of Exchange (the
"TOTAL NUMBER") less (ii) the number of Shares equal to the quotient obtained by
dividing (A) the product of the Total Number and the then existing Exercise
Price by (B) the current market value of a share of Common Stock.

4. ISSUANCE OF CERTIFICATES.

     Upon the exercise of the Warrants, the issuance of certificates for the
Shares shall be made forthwith (and in any event within five business days
thereafter) without charge to the Holder thereof including, without limitation,
any tax which may be payable in respect of the issuance thereof, and such
certificates shall be issued in the name of, or in such names as may be directed
by, the Holder thereof; provided, however, that the Company shall not be
required to pay any tax which may be payable in respect of any transfer involved
in the issuance and delivery of any such certificates in a name other than that
of the Holder and the Company shall not be required to issue or deliver such
certificates unless or until the person or persons requesting the issuance
thereof shall have paid to the Company the amount of such tax or shall have
established to satisfaction of the Company that such tax has been paid.

     The Warrant Certificates and the certificates representing the Shares shall
be executed on behalf of the Company by the manual or facsimile signature of the
present or any future Chairman or Vice Chairman of the Board of Directors, Chief
Executive officer or President or Vice President of the Company under its
corporate seal reproduced thereon, attested to by the manual or facsimile
signature of the present or any future Secretary or Assistant Secretary of the
Company. Warrant Certificates shall be dated the date of execution by the
Company upon initial issuance, division, exchange, substitution or transfer.

     The Warrant Certificates and, upon exercise of the Warrants, in part or in
whole, certificates representing the Shares shall bear a legend substantially
similar to the following:

        The securities represented by this certificate have not been
        registered under the Securities Act of 1933, as amended (the
        "ACT"), and may

                                       H-2
<PAGE>   272

        not be offered or sold except (i) pursuant to an effective
        registration statement under the Act, (ii) to the extent
        applicable, pursuant to Rule 144 under the Act (or any similar
        rule under such Act relating to the disposition of securities),
        or (iii) upon the delivery by the holder to the Company of an
        opinion of counsel, satisfactory to counsel to the issuer,
        stating that an exemption from registration under such Act is
        available.

5. PRICE.

     5.1 ADJUSTED EXERCISE PRICE.  The adjusted Exercise Price shall be the
price which shall result from time to time from any and all adjustments of the
Initial Exercise Price in accordance with the provisions of Article 7 hereof.

     5.2 EXERCISE PRICE.  The term "EXERCISE PRICE" herein shall mean the
Initial Exercise Price or the adjusted Exercise Price, depending upon the
context.

6. REGISTRATION RIGHTS.

     6.1 REGISTRATION UNDER THE SECURITIES ACT OF 1993.  The Warrants and the
Shares have not been registered for purposes of public distribution under the
Securities Act of 1933, as amended ("THE ACT").

     6.2 REGISTRABLE SECURITIES.  As used herein the term "REGISTRABLE SECURITY"
means each of the Warrants, the Shares and any shares of Common Stock issued
upon any stock split or stock dividend in respect of such Shares; provided,
however, that with respect to any particular Registrable Security, such security
shall cease to be a Registrable Security when, as of the date of determination,
(i) it has been effectively registered under the Securities Act and disposed of
pursuant thereto, (ii) registration under the Securities Act is no longer
required for the immediate public distribution of such security or (iii) it has
ceased to be outstanding. The term "REGISTRABLE SECURITIES" means any and/or all
of the securities falling within the foregoing definition of a "Registrable
Security." In the event of any merger, reorganization, consolidation,
recapitalization or other change in corporate structure affecting the Common
Stock, such adjustment shall be made in the definition of "Registrable Security"
as is appropriate in order to prevent any dilution or enlargement of the rights
granted pursuant to this Article 6.

     6.3 PIGGYBACK REGISTRATION.  If, at any time during the five years
following the date of this Agreement, the Company proposes to prepare and file
any registration statement or post-effective amendments (other than in
connection with an underwritten initial public offering or initial registration
of the Company or the Company's securities with the U.S. Securities & Exchange
Commission) thereto covering equity or debt securities of the Company, or any
such securities of the Company held by its shareholders (in any such case, other
than in connection with a merger, acquisition or pursuant to Form S-8 or
successor form), (for purposes of this Article 6, collectively, a "REGISTRATION
STATEMENT"), it will give written notice of its intention to do so by registered
mail ("NOTICE"), at ten (10) business days prior to the filing of each such
Registration Statement, to all holders of the Registrable Securities. Upon the
written request of such a holder (a "REQUESTING HOLDER"), made within ten (10)
business days after receipt of the Notice, that the Company include any of the
Requesting Holder's Registrable Securities in the proposed Registration
Statement, the Company shall, as to each such Requesting Holder, use its best
efforts to effect the registration under the Securities Act of the Registrable
Securities which it has been so requested to register ("PIGGYBACK
REGISTRATION"), at the Company's

                                       H-3
<PAGE>   273

sole cost and expense and at no cost or expense to the Requesting Holders.
Notwithstanding the provisions of this Section 6.3, the Company shall have the
right at any time after it shall have given written notice pursuant to this
Section 6.3 (irrespective of whether any written request for inclusion of such
securities shall have already been made) to elect not to file any such proposed
Registration Statement, or to withdraw the same after the filing but prior to
the effective date thereof.

7. ADJUSTMENTS OF EXERCISE PRICE AND NUMBER OF SHARES.

     7.1 SUBDIVISION AND COMBINATION.  In case the Company shall at any time
subdivide or combine the outstanding shares of Common Stock, the Exercise Price
shall forthwith be proportionately decreased in the case of subdivision or
increased in the case of combination.

     7.2 ADJUSTMENT IN NUMBER OF SHARES.  Upon each adjustment of the Exercise
Price pursuant to the provisions of this Article 7, the number of Shares
issuable upon the exercise of each Warrant shall be adjusted to the nearest full
Share by multiplying a number equal to the Exercise Price in effect immediately
prior to such adjustment by the number of Shares issuable upon exercise of the
Warrants immediately prior to such adjustment and dividing the product so
obtained by the adjusted Exercise Price.

     7.3 RECLASSIFICATION, CONSOLIDATION, MERGER, ETC.  In case of any
reclassification or change of the outstanding shares of Common Stock (other than
a change in par value to no par value, or from no par value to par value, or as
a result of a subdivision or combination), or in the case of any consolidation
of the Company with, or merger of the Company into, another corporation (other
than a consolidation or merger in which the Company is the surviving corporation
and which does not result in any reclassification or change of the outstanding
shares of Common Stock, except a change as a result of a subdivision or
combination of such shares or a change in par value, as aforesaid), or in the
case of a sale or conveyance to another corporation of the property of the
Company as an entirety, the Holders shall thereafter have the right to purchase
the kind and number of shares of stock and other securities and property
receivable upon such reclassification, change, consolidation, merger, sale or
conveyance as if the Holders were the owners of the shares of Common Stock
underlying the Warrants immediately prior to any such events at a price equal to
the product of (x) the number of shares issuable upon exercise of the Warrants
and (y) the Exercise Price in effect immediately prior to the record date for
such reclassification, change, consolidation, merger, sale or conveyance as if
such Holders had exercised the Warrants.

     7.4 NO ADJUSTMENT OF EXERCISE PRICE IN CERTAIN CASES.  No adjustment of the
Exercise Price shall for example be made:

          (a) Upon the issuance or sale of shares of Common Stock upon the
     exercise of the Warrants; or

          (b) Upon (i) the issuance of options pursuant to the Company's
     employee stock option plans in effect or the issuance or sale by the
     Company of any shares of Common Stock pursuant to the exercise of any such
     options, or (ii) the issuance or sale by the Company of any shares of
     Common Stock pursuant to the exercise of any options or warrants; or

          (c) Upon the issuance of shares of Common Stock pursuant to
     contractual obligations; or

                                       H-4
<PAGE>   274

          (d) If the amount of said adjustment shall be less than 2 cents (2c)
     per Share, provided, however, that in such case any adjustment that would
     otherwise be required then to be made shall be carried forward and shall be
     made at the time of and together with the next subsequent adjustment which,
     together with any adjustment so carried forward, shall amount to at least 2
     cents (2c) per Share.

     7.5 DIVIDENDS AND OTHER DISTRIBUTIONS WITH RESPECT TO OUTSTANDING
SECURITIES.  In the event that the Company shall at any time prior to the
exercise of all Warrants declare a dividend (other than a dividend consisting
solely of shares of Common Stock or a cash dividend or distribution payable out
of current or retained earnings) or otherwise distribute to its shareholders any
monies, assets, property, rights, evidences of indebtedness, securities (other
than shares of Common Stock), whether issued by the Company or by another person
or entity, or any other thing of value, the Holder or Holders of the unexercised
Warrants shall thereafter be entitled, in addition to the shares of Common Stock
or other securities receivable upon the exercise thereof, to receive, upon the
exercise of such Warrants, the same monies, property, assets, rights, evidences
of indebtedness, securities or any other thing of value that they would have
been entitled to receive at the time of such dividend or distribution. At the
time of any such dividend or distribution, the Company shall make appropriate
reserves to ensure the timely performance of the provisions of this Subsection
7.5.

8. EXCHANGE AND REPLACEMENT OF WARRANT CERTIFICATES.

     Each Warrant Certificate is exchangeable without expense, upon the
surrender hereof by the registered Holder at the principal executive office of
the Company, for a new Warrant Certificate of like tenor and date representing
in the aggregate the right to purchase the same number of Shares in such
denominations as shall be designated by the Holder thereof at the time of such
surrender.

     Upon receipt by the Company of evidence reasonably satisfactory to it of
the loss, theft, destruction or mutilation of any Warrant Certificate, and, in
case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to it, and reimbursement to the Company of all reasonable expenses
incidental thereto, and upon surrender and cancellation of the Warrants, if
mutilated, the Company will make and deliver a new Warrant Certificate of like
tenor, in lieu thereof.

9. ELIMINATION OF FRACTIONAL INTERESTS.

     The Company shall not be required to issue certificates representing
fractions of shares of Common Stock and shall not be required to issue scrip or
pay cash in lieu of fractional interests, it being the intent of the parties
that all fractional interests shall be eliminated by rounding any fraction up to
the nearest whole number of shares of Common Stock.

10. RESERVATION AND LISTING OF SECURITIES.

     The Company shall at all times reserve and keep available out of its
authorized shares of Common Stock, solely for the purpose of issuance upon the
exercise of the Warrants, such number of shares of Common Stock as shall be
issuable upon the exercise thereof. The Company covenants and agrees that, upon
exercise of the Warrants and payment of the Exercise Price therefor, all shares
of Common Stock issuable upon such exercise shall

                                       H-5
<PAGE>   275

be duly and validly issued, fully paid, non-assessable and not subject to the
preemptive rights of any shareholder. As long as the Warrants shall be
outstanding, the Company shall use its best efforts, once it has become a public
company, to cause all shares of Common Stock issuable upon the exercise of the
Warrants to be listed on or quoted on the electronic bulletin board, by NASDAQ
or listed on such national securities exchanges.

11. NOTICES TO WARRANT HOLDERS.

     Nothing contained in this Agreement shall be construed as conferring upon
the Holder or Holders the right to vote or to consent or to receive notice as a
shareholder in respect of any meetings of shareholders for the election of
directors or any other matter, or as having any rights whatsoever as a
shareholder of the Company. If, however, at any time prior to the expiration of
the Warrants and their exercise, any of the following events shall occur:

          (a) the Company shall take a record of the holders of its shares of
     Common Stock for the purpose of entitling them to receive a dividend or

                       PURCHASE AND SALE OF COMMON STOCK

     Section 2.1 INVESTMENTS.

     (a) PUTS. Upon the terms and conditions set forth herein (including,
without limitation, the provisions of Article VII), on any Put Date the Company

that Investor shall receive pursuant to such Put shall be determined by dividing

2.2(a), deliver to Investor during the Commitment Period, Put Notices with an
aggregate Investment Amount at least equal to the Minimum Commitment Amount. If
the Company for any reason fails to issue and deliver such Put Shares during the
Commitment Period, on the first Trading Day after the expiration of the
Commitment Period, the Company shall wire to Investor a sum in immediately
available funds equal to the product of (i) the Minimum Commitment Amount minus
the aggregate Investment Amounts of the Put Notices delivered to Investor
hereunder and (ii) the Discount.

     (c) MAXIMUM AMOUNT OF PUTS. Unless the Company obtains the requisite
approval of its shareholders in accordance with the corporate laws of the State
of Georgia and the applicable rules of the Principal Market, no more than

pursuant to this Agreement.

                                       I-6
<PAGE>   291

     Section 2.2 MECHANICS.

     (a) PUT NOTICE. At any time during the Commitment Period, the Company may
deliver a Put Notice to Investor, subject to the conditions set forth in Section
7.2; provided, however, the Investment Amount for each Put as designated by the
Company in the applicable Put Notice shall be neither less than the Minimum Put
Amount nor more than the Maximum Put Amount.

     (b) DATE OF DELIVERY OF PUT NOTICE. A Put Notice shall be deemed delivered
on (i) the Trading Day it is received by facsimile or otherwise by Investor if
such notice is received on or prior to 12:00 noon New York time, or (ii) the
immediately succeeding Trading Day if it is received by facsimile or otherwise
after 12:00 noon New York time on a Trading Day or at any time on a day which is
not a Trading Day.

     Section 2.3 CLOSINGS.  On each Closing Date for a Put, (a) the Company
shall deliver to Investor one or more certificates, at Investor's option,
representing the Put Shares to be purchased by Investor pursuant to Section 2.1
herein, registered in the name of Investor and (b) Investor shall deliver to the
Company the Investment Amount specified in the Put Notice by wire transfer of
immediately available funds to an account designated by the Company on or before
the Closing Date. In lieu of delivering physical certificates representing the
Common Stock issuable in accordance with clause (a) of this Section 2.3, and
provided that the Transfer Agent then is participating in the Depository Trust
Company ("DTC") Fast Automated Securities Transfer ("FAST") program, upon
request of Investor, the Company shall use its commercially reasonable efforts
to cause the Transfer Agent to electronically transmit the Put Shares by
crediting the account of the holder's prime broker with DTC through its Deposit
Withdrawal Agent Commission ("DWAC") system. In addition, on or prior to such
Closing Date, each of the Company and Investor shall deliver to the other all
documents, instruments and writings required to be delivered or reasonably
requested by either of them pursuant to this Agreement in order to implement and
effect the transactions contemplated herein.

     Section 2.4 SPECIAL CIRCUMSTANCES; ADJUSTMENT PERIOD.

     (a) ADJUSTMENT PERIOD NOTICE. In the event that the Company shall in good
faith anticipate executing an agreement of acquisition, merger or consolidation
within ninety (90) days after giving Investor Adjustment Period Notice (as
defined below), the Company may, in its sole discretion, give Investor at least
twenty-one (21) days irrevocable advance notice, in the form of Exhibit B hereto
("Adjustment Period Notice"), that the Company shall initiate an Adjustment
Period (as defined below). The Company shall not give such Adjustment Period
Notice if it constitutes the disclosure of material non-public information to
Investor.

     (b) ACTIONS DURING THE ADJUSTMENT PERIOD. During the Adjustment Period:

          (i) the Discount shall be increased to twenty-one percent (21%);

          (ii) the duration of the Trading Cushion shall be shortened to ten
     (10) Trading Days until the expiration of five (5) consecutive weeks after
     the date on which the Adjustment Period Notice was given (the "Adjustment
     Period"); and

          (iii) the Company may not deliver a Put Notice such that the number of
     Put Shares to be purchased by Investor upon the applicable Closing, when
     aggregated with all other shares of Common Stock then owned by Investor
     beneficially or deemed beneficially owned by Investor, would result in
     Investor owning more than

                                       I-7
<PAGE>   292

     4.9% of all of such Common Stock as would be outstanding on such Closing
     Date, as determined in accordance with Section 13(d) of the Exchange Act
     and the regulations promulgated thereunder. For purposes of this Section
     2.4(b)(iii), in the event that the amount of Common Stock outstanding as
     determined in accordance with Section 13(d) of the Exchange Act 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
     Investor, when aggregating all purchases of Common Stock made pursuant to
     this Agreement would own more than 4.9% of the Common Stock following such
     Closing Date.

     Section 2.5 TERMINATION OF INVESTMENT OBLIGATION.  The obligation of
Investor to purchase shares of Common Stock shall terminate permanently without
penalty (including with respect to a Closing Date that has not yet occurred) in
the event that (a) there shall occur any stop order or suspension of the
effectiveness of any Registration Statement for an aggregate of thirty (30)
Trading Days during the Commitment Period, for any reason other than deferrals
or suspension during a Blackout Period in accordance with the Registration
Rights Agreement, as a result of corporate developments subsequent to the
Subscription Date that would require such Registration Statement to be amended
to reflect such event in order to maintain its compliance with the disclosure
requirements of the Securities Act, (b) the Company shall at any time fail to
comply with the requirements of Section 6.3, 6.4, 6.5 or 6.6 and such failure
shall continue for more than thirty (30) days, or (c) the Company shall provide
thirty (30) days notice of termination to Investor.

     Section 2.6 BLACKOUT SHARES.  In the event that, (a) within five Trading
Days following any Closing Date, the Company gives a Blackout Notice to 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 Investor may sell its Registrable Securities
pursuant to an effective Registration Statement ("New Bid Price"), then the
Company shall issue to Investor the number of additional shares of Registrable
Securities (the "Blackout Shares") equal to the difference between (i) the
product of the number of Put Shares held by Investor immediately prior to the
Blackout Period that were issued on the most recent Closing Date (the "Remaining
Put Shares") multiplied by the Old Bid Price, divided by the New Bid Price, and
(ii) the Remaining Put Shares.

     Section 2.7 LIQUIDATED DAMAGES.  Each of the Company and Investor
acknowledge and agree that the sum payable under Section 2.1(b) and the
requirement to issue Blackout Shares under Section 2.6 shall give rise to
liquidated damages and not penalties. Each of the Company and Investor further
acknowledge that (a) the amount of loss or damages likely to be incurred is
incapable or is difficult to precisely estimate, (b) the amounts specified in
such Sections bear a reasonable proportion and are not plainly or grossly
disproportionate to the probable loss likely to be incurred by Investor in
connection with the failure by the Company to make Puts with aggregate Purchase
Prices totaling at least the Minimum Commitment Amount or in connection with a
Blackout Period under the Registration Rights Agreement, and (c) each of the
Company and Investor are sophisticated business parties and have been
represented by sophisticated and able legal and financial counsel and negotiated
this Agreement at arm's length.

the commencement of each calendar quarter occurring subsequent to the
commencement of the Commitment Period, the Company undertakes to notify Investor
as to its reasonable expectations as to the dollar amount it intends to raise

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 Investor at
any time as to its reasonable expectations with respect to the current calendar
quarter.

been declared effective by the SEC prior to the first Put Date, and in any event

Securities other than the Initial Registrable Securities, the Company shall have
filed with the SEC a Registration Statement with respect to the resale of such

the SEC prior to the Put Date therefor.

     (b) Effective Registration Statement. As set forth in the Registration

effective for the resale by Investor of the Registrable Securities subject to
such Put Notice and such Registration Statement shall remain effective on each
Condition Satisfaction Date and (i) neither the Company nor Investor shall have
received notice that the SEC has issued or intends to issue a stop order with
respect to such Registration Statement or that the SEC otherwise has suspended
or withdrawn the effectiveness of such Registration Statement, either
temporarily or permanently, or intends or has threatened to do so (unless the
SEC's concerns have been addressed and Investor is reasonably satisfied that the
SEC no longer is considering or intends to take such action), and (ii) no other
suspension of the use or

                                      I-16

representations and warranties of the Company shall be true and correct in all
material respects as of each Condition Satisfaction Date as though made at each
such time (except for representations and warranties specifically made as of a
particular date) with respect to all periods, and as to all events and
circumstances occurring or existing to and including each Condition Satisfaction
Date, except for any conditions which have temporarily caused any
representations or warranties herein to be incorrect and which have been
corrected with no continuing impairment to the Company or Investor.

     (d) Performance by the Company. The Company shall have performed, satisfied
and complied in all material respects with all covenants, agreements and
conditions required by this Agreement and the Registration Rights Agreement to
be performed, satisfied or complied with by the Company at or prior to each
Condition Satisfaction Date.

     (e) No Injunction. No statute, rule, regulation, executive order, decree,
ruling or injunction shall have been enacted, entered, promulgated or adopted by
any court or governmental authority of competent jurisdiction that prohibits or
directly and materially adversely affects any of the transactions contemplated

effect of prohibiting or materially adversely affecting any of the transactions
contemplated by this Agreement.

SEC Document, no event that had or is reasonably likely to have a Material
Adverse Effect has occurred.

     (h) Legal Opinion. The Company shall have caused to be delivered to
Investor, within five (5) Trading Days of the effective date of the Initial

Investor.

     (i) Due Diligence. No dispute between the Company and Investor shall exist
pursuant to Section 7.3 as to the adequacy of the disclosure contained in any
Registration Statement.

     (j) Ten Percent Limitation. On each Closing Date, the number of Put Shares
then to be purchased by Investor shall not exceed the number of such shares
that, when aggregated with all other shares of Registrable Securities then owned
by Investor beneficially or deemed beneficially owned by Investor, would result
in Investor owning no more than 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 7.2(j), 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

                                      I-17
<PAGE>   302

of determining whether Investor, when aggregating all purchases of Common Stock
made pursuant to this Agreement and Blackout Shares, if any, would own more than
9.9% of the Common Stock following such Closing Date.

     (k) Minimum Bid Price. The average of the Bid Prices for the twenty (20)
Trading Days immediately preceding the Put Notice shall have equaled or exceeded
$1.00 (as adjusted for stock splits, stock dividends, reverse stock splits, and
similar events).

     (l) 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).

     (m) Trading Cushion. The Trading Cushion shall have elapsed since the
immediately preceding Put Date.

     (n) Shareholder Vote. The issuance of shares of Common Stock with respect
to the applicable Closing, if any, shall not violate the shareholder approval
requirements of the Principal Market.

     (o) Other. On each Condition Satisfaction Date, Investor shall have
received and been reasonably satisfied with such other certificates and
documents as shall have been reasonably requested by Investor in order for
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 D hereto, executed 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; NON-DISCLOSURE OF NON-PUBLIC INFORMATION.

     (a) The Company shall make available for inspection and review by Investor,
advisors to and representatives of Investor (who may or may not be affiliated
with Investor and who are reasonably acceptable to the Company), any
Underwriter, 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 Investor 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 such Registration Statement for the sole
purpose of enabling Investor 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 such Registration
Statement.

     (b) Each of the Company, its officers, directors, employees and agents
shall in no event disclose non-public information to Investor, advisors to or
representatives of Investor (including, without limitation, in connection with
the giving of the Adjustment Period Notice pursuant to Section 2.4) unless prior
to disclosure of such information the Company identifies such information as
being non-public information and provides Investor, such advisors and
representatives with the opportunity to accept or refuse to accept such
non-public information for review. The Company may, as a condition to

                                      I-18
<PAGE>   303

disclosing any non-public information hereunder, require Investor's advisors and
representatives to enter into a confidentiality agreement in form and substance
reasonably satisfactory to the Company and Investor.

     (c) Nothing herein shall require the Company to disclose non-public
information to Investor or its advisors or representatives, and the Company
represents that it does not disseminate 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 shall, as hereinabove provided, immediately notify the
advisors and representatives of Investor and 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 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 a 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 7.3 shall be construed to mean that such
persons or entities other than Investor (without the written consent of Investor
prior to disclosure of such information) may not obtain non-public information
in the course of conducting due diligence in accordance with the terms and
conditions 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, any Registration Statement contains an
untrue statement of a material fact or omits a material fact required to be
stated in such Registration Statement or necessary to make the statements
contained therein, in light of the circumstances in which they were made, not
misleading.

                                    LEGENDS

     Section 8.1 LEGENDS.  Unless otherwise provided below, each certificate
representing Registrable Securities will bear the following legend (the
"Legend"):

          The securities represented by this certificate have not been
     registered under the Securities Act of 1933 (the "Securities Act") or
     qualified under applicable state securities laws. These securities may not
     be offered, sold, pledged, hypothecated, transferred or otherwise disposed
     of except pursuant to (i) an effective registration statement and
     qualification in effect with respect thereto under the Securities Act and
     under any applicable state securities law, (ii) to the extent applicable,
     Rule 144 under the Securities Act, or (iii) an opinion of counsel
     reasonably acceptable to BioShield Technologies, Inc. that such
     registration and qualification is not required under applicable federal and
     state securities laws.

     As soon as practicable after the execution and delivery hereof, the Company
shall issue to the Transfer Agent instructions in substantially the form of
Exhibit E hereto. Such instructions shall be irrevocable by the Company from and
after the date thereof or from and after the issuance thereof 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 to issue to Investor certificates evidencing shares of Common

                                      I-19
<PAGE>   304

Stock incident to a Closing, free of the Legend, 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 Investor; provided that (a) a Registration
Statement shall then be effective, (b) Investor confirms to the Transfer Agent
and the Company that it has or intends to sell such Common Stock to a third
party which is not an affiliate of Investor or the Company and Investor agrees
to redeliver the certificate representing such shares of Common Stock to the
Transfer Agent to add the Legend in the event the Common Stock is not sold, and
(c) if reasonably requested by the transfer agent or the Company, Investor
confirms to the transfer agent and the Company that Investor has complied with
the prospectus delivery requirement under the Securities Act. At any time after
the Effective Date, upon surrender of one or more certificates evidencing Common
Stock 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

     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 Common Stock 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 Investor's obligations under any agreement to comply with all
applicable securities laws upon resale of the Common Stock.

     Section 9.2 INDEMNIFICATION.

     (a) The Company agrees to indemnify and hold harmless Investor and its
officers, directors, employees, and agents, and each Person or entity, if any,
who controls 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 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 such Damages result primarily from Investor's failure to perform any
covenant or agreement contained in this Agreement or Investor's or its officers,
directors, employees, agents or Controlling Persons negligence, recklessness or
bad faith in performing its obligations under this Agreement.

     (b) Investor agrees to indemnify and hold harmless the Company and its
officers, directors, employees, and agents, and each Person or entity, if any,
who controls Investor within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act, together with the Controlling Persons from and
against any Damages, joint or several, and

                                      I-21
<PAGE>   306

any action in respect thereof to which 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 such Damages
result primarily from the Company's failure to perform any covenant or agreement
contained in this Agreement or the Company's or its officers, directors,
employees, agents or Controlling Persons negligence, recklessness or bad faith
in performing its obligations under this Agreement.

     Section 9.3 METHOD OF ASSERTING INDEMNIFICATION CLAIMS. All claims for
indemnification by any Indemnified Party (as defined below) under Section 9.2
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 9.2 (an "Indemnified
Party") might seek indemnity under Section 9.2 is asserted against or sought to
be collected from such Indemnified Party by a person other than a party hereto
or an affiliate thereof (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 that is being asserted under any
provision of Section 9.2 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 prejudiced by such failure of the Indemnified Party. The Indemnifying Party
shall notify the Indemnified Party as soon as practicable within the period
ending thirty (30) 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 to the Indemnified Party under Section 9.2 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 9.3(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 9.2). 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 the sole cost and expense
of the Indemnified Party, at any time prior to the Indemnifying Party's delivery
of the notice

                                      I-22
<PAGE>   307

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; 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 except as
provided in the preceding sentence, the Indemnified Party shall bear its own
costs and expenses with respect to such participation. 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 9.2 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 9.3(a), or if the Indemnifying Party gives such notice
but fails to prosecute vigorously and diligently or settle the Third Party
Claim, or if the Indemnifying Party fails to give any notice whatsoever within
the Dispute Period, 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. Notwithstanding the foregoing provisions of this clause (ii), if the
Indemnifying Party has notified the Indemnified Party within the Dispute Period
that the Indemnifying Party disputes its liability or the amount of its
liability hereunder to the Indemnified Party with respect to such Third Party
Claim and if such dispute is resolved in favor of the Indemnifying Party in the
manner provided in clause (iii) below, the Indemnifying Party will not be
required to bear the costs and expenses of the Indemnified Party's defense
pursuant to this clause (ii) or of the Indemnifying Party's participation
therein at the Indemnified Party's request, and the Indemnified Party shall
reimburse the Indemnifying Party in full for all reasonable costs and expenses
incurred by the Indemnifying Party in connection with such litigation. The
Indemnifying Party may participate in, but not control, any defense or
settlement controlled by the Indemnified Party pursuant to this clause (ii), and
the Indemnifying Party shall bear its own costs and expenses with respect to
such participation.

     (iii) If the Indemnifying Party notifies the Indemnified Party that it does
not dispute its liability or the amount of its liability to the Indemnified
Party with respect to the Third Party Claim under Section 9.2 or fails to notify
the Indemnified Party within the Dispute Period whether the Indemnifying Party
disputes its liability or the amount of its liability to the Indemnified Party
with respect to such Third Party Claim, the amount of Damages specified in the
Claim Notice shall be conclusively deemed a liability of the Indemnifying Party
under Section 9.2 and the Indemnifying Party shall pay the amount of such
Damages 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

                                      I-23
<PAGE>   308

Indemnifying Party and the Indemnified Party shall proceed in good faith to
negotiate a resolution of such dispute; provided, however, that it the dispute
is not resolved within thirty (30) days after the Claim Notice, the Indemnifying
Party shall be enlisted to institute such legal action as it deems appropriate.

     (b) In the event any Indemnified Party should have a claim under Section
9.2 against the Indemnifying Party that does not involve a Third Party Claim,
the Indemnified Party shall deliver a written notification of a claim for
indemnity under Section 9.2 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 demonstrates that it
has been irreparably 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 amount of the claim described in such Indemnity Notice, the amount of
Damages specified in the Indemnity Notice will be conclusively deemed a
liability of the Indemnifying Party under Section 9.2 and the Indemnifying Party
shall pay the amount of such Damages 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;
provided, however, that it the dispute is not resolved within thirty (30) days
after the Claim Notice, the Indemnifying Party shall be enlisted to institute
such legal action as it deems appropriate.

                                 MISCELLANEOUS

     Section 10.1 GOVERNING LAW; JURISDICTION.  This Agreement shall be governed
by and interpreted in accordance with the laws of the State of Georgia without
regard to the principles of conflicts of law. Each of the Company and Investor
hereby submit to the exclusive jurisdiction of the United States Federal and
state courts located in Atlanta, Georgia with respect to any dispute arising
under this Agreement, the agreements entered into in connection herewith or the
transactions contemplated hereby or thereby.

     Section 10.2 ASSIGNMENT.  This Agreement shall be binding upon and inure to
the benefit of the Company and Investor and their respective successors and
permitted assigns. Neither this Agreement nor any rights of Investor or the
Company hereunder may be assigned by either party to any other person.
Notwithstanding the foregoing, (a) the provisions of this Agreement shall inure
to the benefit of, and be enforceable by, any transferee of any of the Common
Stock purchased or acquired by Investor hereunder with respect to the Common
Stock held by such person, and (b) Investor's interest in this Agreement may be
assigned at any time, in whole but not in part, to any affiliate of Investor.

     Section 10.3 THIRD PARTY BENEFICIARIES.  This Agreement is intended for the
benefit of the Company and Investor and their respective successors and
permitted assigns, and is not for the benefit of, nor may any provision hereof
be enforced by, any other person.

<PAGE>   309

     Section 10.4 TERMINATION.  This Agreement shall terminate twelve (12)
months after the commencement of the Commitment Period (unless extended by the
agreement of the Company and Investor); provided, however, that the provisions
of Article VI, VIII, and Sections 10.1, 10.2, and 10.4 shall survive the
termination of this Agreement.

     Section 10.5 ENTIRE AGREEMENT, AMENDMENT; NO WAIVER.  This Agreement and
the instruments referenced herein contain the entire understanding of the
Company and Investor with respect to the matters covered herein and therein and,
except as specifically set forth herein or therein, neither the Company nor
Investor makes any representation, warranty, covenant or undertaking with
respect to such matters. No provision of this Agreement may be waived or amended
other than by an instrument in writing signed by the party to be charged with
enforcement.

     Section 10.6 FEES AND EXPENSES.  Each of the Company and Investor agrees to
pay its own expenses in connection with the preparation of this Agreement and
performance of its obligations hereunder.

     Section 10.7 NO BROKERS.  Each of the Company and Investor represents that
other than J.P. Carey Securities, Inc. and Greenfield Capital Partners, LLC (for
which the Company shall be responsible for the fees of such entities) 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 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.

     Section 10.8 COUNTERPARTS.  This Agreement may be executed in multiple
counterparts, each of which may be executed by less than all of the Company and
Investor and shall be deemed to be an original instrument which shall be
enforceable against the parties actually executing such counterparts and all of
which together shall constitute one and the same instrument. This Agreement,
once executed by a party, may be delivered to the other parties hereto by
facsimile transmission of a copy of this Agreement bearing the signature of the
parties so delivering this Agreement.

     Section 10.9 SURVIVAL; SEVERABILITY.  The representations, warranties,
covenants and agreements of the parties hereto shall survive each Closing
hereunder for a period of one year. In the event that any provision of this
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
effect without said provision; provided that such severability shall be
ineffective if it materially changes the economic benefit of this Agreement to
any party.

     Section 10.10 FURTHER ASSURANCES.  Each party shall do and perform, or
cause to be done and performed, all such further acts and things, and shall
execute and deliver all such other agreements, certificates, instruments and
documents, as the other party may reasonably request in order to carry out the
intent and accomplish the purposes of this Agreement and the consummation of the
transactions contemplated hereby.

     Section 10.11 NO STRICT CONSTRUCTION.  The language used in this Agreement
will be deemed to be the language chosen by the parties to express their mutual
intent, and no rules of strict construction will be applied against any party.

     Section 10.12 EQUITABLE RELIEF.  The Company recognizes that in the event
that it fails to perform, observe, or discharge any or all of its obligations
under this Agreement, any remedy at law may prove to be inadequate relief to
Investor. The Company therefore agrees that Investor shall be entitled to
temporary and permanent injunctive relief in any such case without the necessity
of proving actual damages.

     Section 10.13 TITLE AND SUBTITLES.  The titles and subtitles used in this
Agreement are used for the convenience of reference and are not to be considered
in construing or interpreting this Agreement.

     Section 10.14 REPORTING ENTITY FOR THE COMMON STOCK.  The reporting entity
relied upon for the determination of the trading price of the Common Stock on
any given Trading Day for the purposes of this Agreement shall be Bloomberg L.P.
or any successor thereto. The written mutual consent of Investor and the Company
shall be required to employ any other reporting entity.

                         REGISTRATION RIGHTS AGREEMENT

     REGISTRATION RIGHTS AGREEMENT (this "Agreement"), dated as of June 30,
1999, is made and entered into by and between BIOSHIELD TECHNOLOGIES, INC., a
Georgia corporation (the "Company"), and JACKSON, LLC, a Cayman Island limited
liability company (the "Investor").

     WHEREAS, the Company and the Investor have entered into that certain
Private Equity Credit Agreement dated as of the date hereof (the "Investment
Agreement"), pursuant to which the Company may issue and sell, from time to
time, to the Investor up to $6,250,000 worth of shares of its common stock, no
par value per share (the "Common Stock"); and

     WHEREAS, pursuant to the terms of, and in partial consideration for, the
Investor's agreement to enter into the Investment Agreement, the Company has
agreed to provide the Investor with certain registration rights with respect to
the Registrable Securities;

     NOW, THEREFORE, in consideration of the premises, the representations,
warranties, covenants and agreements contained herein and in the Investment
Agreement, and for other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, intending to be legally bound
hereby, the parties hereto agree as follows (capitalized terms used herein and
not defined herein shall have the respective meanings ascribed to them in the
Investment Agreement):

                                   ARTICLE I

                              REGISTRATION RIGHTS

     1.1 FORM SB-2 REGISTRATION STATEMENTS.

     (a) FILING OF FORM SB-2 REGISTRATION STATEMENT.  Subject to the terms and
conditions of this Agreement, the Company shall (i) prepare and, within one
hundred forty (140) days following the Subscription Date, deliver to the
Investor a draft of a registration statement on Form SB-2 under the Securities
Act (the "Initial Registration Statement") for the registration for the resale
by the Investor of at least one million (1,000,000) Registrable Securities (the
"Initial Registrable Securities") and accompanied or preceded by a questionnaire
(a "Selling Shareholder Questionnaire") and of the type commonly used for
offerings of this kind and (ii) within ten (10) days after the Company has
received comments, if any, and a properly completed Selling Shareholder
Questionnaire from the Investor, file the Initial Registration Statement with
the SEC. Thereafter, if the Company desires to issue and sell to the Investor
any Registrable Securities in addition to the Initial Registrable Securities,
the Company shall first file with the SEC a registration statement on Form SB-2
under the Securities Act (the Initial Registration Statement and any subsequent
registration statement, each a "Registration Statement").

     (b) EFFECTIVENESS OF THE INITIAL REGISTRATION STATEMENT.  The Company shall
use its commercially reasonable efforts (i) to have the Initial Registration
Statement declared effective by the SEC by no later than one hundred and twenty
(120) days after the filing of the Initial Registration Statement, and (ii) to
ensure that the Initial Registration

                                       J-1
<PAGE>   320

Statement and any subsequent Registration Statement remains in effect throughout
the term of this Agreement as set forth in Section 4.2, subject to the terms and
conditions of this Agreement.

     [(c) FAILURE TO MAINTAIN EFFECTIVENESS OF A REGISTRATION STATEMENT.  In the
event the Company fails to maintain the effectiveness of any Registration
Statement (or the underlying prospectus) throughout the term of this Agreement,
other than temporary suspensions permitted by Section 1.1(e), and the Investor
holds any Registrable Securities at any time during the period of such
ineffectiveness (an "Ineffective Period"), the Company shall pay to the Investor
in immediately available funds into an account designated by the Investor an
amount equal to one percent (1%) of the aggregate Purchase Price of all of the
Registrable Securities then held by the Investor for each thirty (30) calendar
day period (prorated for partial periods) of such Ineffective Period; provided,
that the Company shall be entitled to credit against any such payment the value
of the Blackout Shares (based on the applicable New Bid Price) issued to the
Investor pursuant to Section 2.6 of the Investment Agreement. The payments
required by this Section 1.1(d) shall be made on the first Trading Day after the
earliest to occur of (i) the expiration of the Commitment Period, and (ii) the
expiration of an Ineffective Period (or if an Ineffective Period shall last more
than thirty (30) calendar days, the expiration of each thirty (30) calendar days
of an Ineffective Period).]

     (d) DEFERRAL OR SUSPENSION DURING A BLACKOUT PERIOD.  Notwithstanding the
provisions of Section 1.1 (c), if the Company shall furnish to the Investor
notice (a "Blackout Notice") signed by the Chief Executive Officer or Chief
Financial Officer of the Company stating that he has determined in good faith
that it would be seriously detrimental to the Company and its shareholders for
the Initial Registration Statement to be filed (or for any Registration
Statement to remain in effect) and it is therefore desirable to defer the filing
of such Initial Registration Statement (or temporarily suspend the effectiveness
of any Registration Statement or use of the related prospectus), the Company
shall have the right (i) immediately to defer such filing for a period of not
more than thirty (30) days beyond the date by which such Initial Registration
Statement was otherwise required hereunder to be filed or (ii) suspend the
effectiveness of any Registration Statement for a period of not more than thirty
(30) days (any such deferral or suspension period of up to thirty days, a
"Blackout Period"). The Investor acknowledges that it would be seriously
detrimental to the Company and its shareholders for such initial Registration
Statement to be filed (or for any Registration Statement to remain in effect)
during a Blackout Period and therefore essential to defer such filing (or
suspend such effectiveness) during such Blackout Period, and agrees to cease any
disposition of Registrable Securities during such Blackout Period. The Company
may not utilize any of its rights under this Section 1.1(d) to defer the filing
of a Registration Statement (or suspend its effectiveness) more than twice in
any twelve (12) month period. Following such deferral or suspension, the
Investor shall be entitled to such additional number of shares of Common Stock
as set forth in Section 2.7 of the Investment Agreement.

     (e) LIQUIDATED DAMAGES.  The Company and the Investor hereto acknowledge
and agree that the sums payable under subsection 1(c) above shall constitute
liquidated damages and not penalties. The parties further acknowledge that (i)
the amount of loss or damages likely to be incurred is incapable or is difficult
to precisely estimate, (ii) the amounts specified in such subsections bear a
reasonable relationship to, and are not plainly or grossly disproportionate to,
the probable loss likely to be incurred in connection with any failure by the
Company to obtain or maintain the effectiveness of a Registration

                                       J-2
<PAGE>   321

Statement, (iii) one of the reasons for the Company and the Investor reaching an
agreement as to such amounts was the uncertainty and cost of litigation
regarding the question of actual damages, and (iv) the Company and the Investor
are sophisticated business parties and have been represented by sophisticated
and able legal counsel and negotiated this Agreement at arm's length.

                                   ARTICLE II

                            REGISTRATION PROCEDURES

     Section 2.1 FILINGS; INFORMATION.  The Company will effect the registration
and sale of the Registrable Securities in accordance with the intended methods
of disposition thereof. Without limiting the foregoing, the Company in each such
case will do the following as expeditiously as possible, but in no event later
than the deadline, if any, prescribed therefor in this Agreement:

          (a) The Company shall (i) prepare and file with the SEC a Registration
     Statement on Form SB-2 (if use of such form is then available to the
     Company pursuant to the rules of the SEC and, if not, on such other form
     promulgated by the SEC for which the Company then qualifies, that counsel
     for the Company shall deem appropriate and which form shall be available
     for the sale of the Registrable Securities to be registered thereunder in
     accordance with the provisions of this Agreement and in accordance with the
     intended method of distribution of such Registrable Securities); (ii) use
     commercially reasonable efforts to cause such filed Registration Statement
     to become and remain effective (pursuant to Rule 415 under the Securities
     Act or otherwise); (iii) 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 for the time period prescribed by Section 1.1(b); and
     (iv) comply with the provisions of the Securities Act with respect to the
     disposition of all securities covered by such Registration Statement during
     such period in accordance with the intended methods of disposition by the
     Investor set forth in such Registration Statement.

          (b) The Company shall file all necessary amendments to any
     Registration Statement in order to effectuate the purpose of this Agreement
     and the Investment Agreement.

          (c) No later than five (5) days prior to filing any amendment or
     supplement to the Initial Registration Statement or any subsequent
     Registration Statement or prospectus, or any amendment or supplement
     thereto (excluding, in each case, amendments deemed to result from the
     filing of documents incorporated by reference therein), or such shorter
     period as is reasonable under the circumstances, the Company shall deliver
     to the Investor and one firm of counsel representing the Investor, in
     accordance with the notice provisions of Section 4.8, copies of such
     Registration Statement as proposed to be filed, together with exhibits
     thereto, which documents will be subject to review by the Investor and such
     counsel, and thereafter deliver to the Investor and such counsel, in
     accordance with the notice provisions of Section 4.8, such number of copies
     of the Registration Statement, each amendment and supplement thereto (in
     each case including all exhibits thereto), the prospectus included in such
     Registration Statement (including each preliminary prospectus) and

                                       J-3
<PAGE>   322

     such other documents or information as the Investor or counsel may
     reasonably request in order to facilitate the disposition of the
     Registrable Securities.

          (d) The Company shall deliver, in accordance with the notice
     provisions of Section 4.8, to each seller of Registrable Securities covered
     by a Registration Statement, such number of conformed copies of such
     Registration Statement and of each amendment and supplement thereto (in
     each case including all exhibits and documents incorporated by reference),
     such number of copies of the prospectus contained in any Registration
     Statement (including each preliminary prospectus and any summary
     prospectus) and any other prospectus filed under Rule 424 promulgated under
     the Securities Act relating to such seller's Registrable Securities, and
     such other documents, as such seller may reasonably request to facilitate
     the disposition of its Registrable Securities.

          (e) After the filing of a Registration Statement, the Company shall
     promptly notify the Investor of any stop order issued or threatened by the
     SEC in connection therewith and take all reasonable actions required to
     prevent the entry of such stop order or to remove it if entered.

          (f) The Company shall use its commercially reasonable efforts to (i)
     register or qualify the Registrable Securities under such other securities
     or blue sky laws of such jurisdictions in the United States as the Investor
     may reasonably request in light of its intended plan of distribution and
     (ii) cause the Registrable Securities to be registered with or approved by
     such other governmental agencies or authorities in the United States as may
     be necessary by virtue of the business and operations of the Company, and
     do any and all other acts and things that may be reasonably necessary or
     advisable to enable the Investor to consummate the disposition of the
     Registrable Securities in light of its intended plan of distribution;
     provided, however, that the Company will not be required to qualify
     generally to do business in any jurisdiction where it would not otherwise
     be required to qualify but for this paragraph (f), subject itself to
     taxation in any such jurisdiction, or consent or subject itself to general
     service of process in any such jurisdiction.

          (g) The Company shall immediately notify the Investor upon the
     occurrence of any of the following events in respect of a Registration
     Statement or related prospectus in respect of an offering of Registrable
     Securities: (i) receipt of any request by the SEC or any other federal or
     state governmental authority for additional information, amendments or
     supplements to such Registration Statement or related prospectus; (ii) the
     issuance by the SEC or any other federal or state governmental authority of
     any stop order suspending the effectiveness of such Registration Statement
     or notification of the initiation of any proceedings for that purpose;
     (iii) receipt of any notification with respect to the suspension of the
     qualification or exemption from 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 such Registration Statement, related prospectus or documents so that, in
     the case of such 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, in the light of the circumstances under which they were made,
     and that in the case of the related

                                       J-4
<PAGE>   323

     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 such Registration
     Statement would be appropriate, and the Company will promptly make
     available to the Investor any such supplement or amendment to the related
     prospectus.

          (h) The Company shall enter into customary agreements and take such
     other customary actions as are reasonably required in order to expedite or
     facilitate the disposition by the Investor of such Registrable Securities
     (whereupon the Investor may, at its option, require that any or all of the
     representations, warranties and covenants of the Company also be made to
     and for the benefit of the Investor).

          (i) The Company shall make available to the Investor (and will deliver
     to Investor's counsel), subject to restrictions imposed by the United
     States federal government or any agency or instrumentality thereof, copies
     of all correspondence between the SEC and the Company, its counsel or its
     auditors and will also make available for inspection by the Investor and
     any attorney, accountant or other professional retained by the Investor
     (collectively, the "Inspectors"), all financial and other records,
     pertinent corporate documents and properties of the Company (collectively,
     the "Records") as shall be reasonably necessary to enable them to exercise
     their due diligence responsibility, and cause the Company's officers and
     employees to supply all information reasonably requested by any Inspectors
     in connection with a Registration Statement. Records that the Company
     determines, in good faith, to be confidential and that it notifies the
     Inspectors are confidential shall not be disclosed by the Inspectors unless
     (i) the disclosure of such Records is necessary to avoid or correct a
     misstatement or omission in any Registration Statement or (ii) the
     disclosure or release of such Records is requested or required pursuant to
     oral questions, interrogatories, requests for information or documents or a
     subpoena or other order from a court of competent jurisdiction or other
     legal process; provided, however, that prior to any disclosure or release
     pursuant to clause (ii), the Inspectors shall provide the Company with
     prompt notice of any such request or requirement so that the Company may
     seek an appropriate protective order or waive such Inspectors' obligation
     not to disclose such Records; and, provided, further, that if failing the
     entry of a protective order or the waiver by the Company permitting the
     disclosure or release of such Records, the Inspectors, upon advice of
     counsel, are compelled to disclose such Records, the Inspectors may
     disclose that portion of the Records that counsel has advised the
     Inspectors that the Inspectors are compelled to disclose. The Investor
     agrees that information obtained by it as a result of such inspections (not
     including any information obtained from a third party who, insofar as is
     known to the Investor after reasonable inquiry, is not prohibited from
     providing such information by a contractual, legal or fiduciary obligation
     to the Company) shall be deemed confidential and shall not be used by it as
     the basis for any market transactions in the securities of the Company
     unless and until such information has been made generally available to the
     public. The Investor further agrees that it will, upon learning that
     disclosure of such Records is sought in a court of competent jurisdiction,
     give notice to the Company and allow the Company, at its expense, to
     undertake appropriate action to prevent disclosure of the Records deemed
     confidential.

          (j) The Company shall otherwise comply with all applicable rules and
     regulations of the SEC, including, without limitation, compliance with
     applicable reporting requirements under the Exchange Act.

          (k) The Company may require the Investor to promptly furnish in
     writing to the Company such information as may be legally required in
     connection with such registration including, without limitation, all such
     information as may be requested by the SEC or the NASD. The Investor agrees
     to provide such information requested in connection with such registration
     within five (5) calendar days after receiving such written request, or such
     shorter period as is reasonable under the circumstances, and the Company
     shall not be responsible for any delays in obtaining or maintaining the
     effectiveness of any Registration Statement caused by the Investor's
     failure to timely provide such information.

     Section 2.2 REGISTRATION EXPENSES.  In connection with each Registration
Statement, the Company shall pay all registration expenses incurred in
connection with the registration thereunder (the "Registration Expenses"),
including, without limitation: (a) all registration, filing, securities exchange
listing and fees required by the NASD, (b) all registration, filing,
qualification and other fees and expenses of compliance with securities or blue
sky laws (including reasonable fees and disbursements of counsel for the
Company), (c) all word-processing, duplicating, printing, messenger and delivery
expenses, (d) the Company's internal expenses (including, without limitation,
all salaries and expenses of its officers and employees performing legal or
accounting duties), and (e) reasonable fees and disbursements of counsel for the
Company and customary fees and expenses for independent certified public
accountants retained by the Company.

                                  ARTICLE III

                        INDEMNIFICATION AND CONTRIBUTION

     Section 3.1 INDEMNIFICATION.

     (a) INDEMNIFICATION BY THE COMPANY.  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 partners, Affiliates,
officers, directors, employees and duly authorized agents of such controlling
Person or entity (collectively, the "Controlling Persons"), from and against any
loss, claim, damage, liability, costs and expenses (including, without
limitation, reasonable attorneys' fees and disbursements and costs and expenses
of investigating and defending any such claim) (collectively, "Damages"), joint
or several, and any action or proceeding in respect thereof to which the
Investor, its partners, Affiliates, officers, directors, employees and duly
authorized agents, and any Controlling Person, may become subject under the
Securities Act or otherwise, as incurred, insofar as such Damages (or actions or
proceedings in respect thereof) arise out of, or are based upon, any untrue
statement or alleged untrue statement of a material fact contained in any
Registration Statement, preliminary prospectus or prospectus relating to the
Registrable Securities or arises out of, or are based upon, any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading in light of the
circumstances under which they were made, except insofar as any such untrue
statement, alleged untrue statement, omission or alleged omission is made

                                       J-6
<PAGE>   325

in reliance upon and in conformity with written information furnished to the
Company by the Investor which is specifically intended by the Investor for use
in the preparation of any such Registration Statement, preliminary prospectus or
prospectus, and shall reimburse the Investor, its partners, Affiliates,
officers, directors, employees and duly authorized agents, and each such
Controlling Person, for any legal and other expenses reasonably incurred by the
Investor, its partners, Affiliates, officers, directors, employees and duly
authorized agents, or any such Controlling Person, as incurred, in investigating
or defending or preparing to defend against any such Damages or actions or
proceedings; provided, however, that the Company shall not be liable to the
Investor to the extent that any such Damages arise out of or are based upon an
untrue statement or omission made in any preliminary prospectus if (i) the
Investor failed to send or deliver a copy of the final prospectus delivered by
the Company to the Investor with or prior to the delivery of written
confirmation of the sale by the Investor to the Person asserting the claim from
which such Damages arise, and (ii) the final prospectus would have corrected
such untrue statement or alleged untrue statement or such omission or alleged
omission.

     (b) INDEMNIFICATION BY THE INVESTOR.  The Investor agrees to indemnify and
hold harmless the Company, its Affiliates, officers, directors, employees and
duly authorized agents, and each Controlling Persons of the Company, from and
against any and all Damages, joint or several, and any action or proceeding in
respect thereof to which the Investor, its partners, Affiliates, officers,
directors, employees and duly authorized agents, and any such Controlling
Person, may become subject under the Securities Act or otherwise, as incurred,
insofar as such Damages (or actions or proceedings in respect thereof) arise out
of, or are based upon, any untrue statement or alleged untrue statement of a
material fact contained in any Registration Statement, preliminary prospectus or
prospectus relating to the Registrable Securities or arises out of, or are based
upon, any omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading
in light of the circumstances under which they were made, but only to the extent
that any such untrue statement, alleged untrue statement, omission or alleged
omission is made in reliance upon and in conformity with written information
furnished to the Company by the Investor which is specifically intended for by
the Investor for use in the preparation of any such Registration Statement,
preliminary prospectus or prospectus, and shall reimburse the Company, its
partners, Affiliates, officers, directors, employees and duly authorized agents,
and each such Controlling Person, for any legal and other expenses reasonably
incurred by the Investor, its partners, Affiliates, officers, directors,
employees and duly authorized agents, or any such Controlling Person, as
incurred, in investigating or defending or preparing to defend against any such
Damages or actions or proceedings.

     Section 3.2 CONDUCT OF INDEMNIFICATION PROCEEDINGS.  Promptly after receipt
by any person or entity in respect of which indemnity may be sought pursuant to
Section 3.1 (an "Indemnified Party") of notice of any claim or the commencement
of any action, the Indemnified Party shall, if a claim in respect thereof is to
be made against the person or entity against whom such indemnity may be sought
(the "Indemnifying Party"), notify the Indemnifying Party in writing of the
claim or the commencement of such action. In the event an Indemnified Party
shall fail to give such notice as provided in this Section 3.2 and the
Indemnifying Party to whom notice was not given was unaware of the proceeding to
which such notice would have related and was prejudiced by the failure to give
such notice, the indemnification provided for in Section 3.1 shall be reduced to
the extent of any actual prejudice resulting from such failure to so notify the
Indemnifying Party; provided, however, that the failure to notify the
Indemnifying Party shall not relieve the

                                       J-7
<PAGE>   326

Indemnifying Party from any liability that it may have to an Indemnified Party
otherwise than under Section 3.1. If any such claim or action shall be brought
against an Indemnified Party, and it shall notify the Indemnifying Party
thereof, the Indemnifying Party shall be entitled to participate therein, and,
to the extent that it wishes, jointly with any other similarly notified
Indemnifying Party, to assume the defense thereof with counsel reasonably
satisfactory to the Indemnified Party. After notice from the Indemnifying Party
to the Indemnified Party of its election to assume the defense of such claim or
action, the Indemnifying Party shall not be liable to the Indemnified Party for
any legal or other expenses subsequently incurred by the Indemnified Party in
connection with the defense thereof other than reasonable costs of
investigation; provided, however, that the Indemnified Party shall have the
right to employ separate counsel to represent the Indemnified Party and its
Controlling Persons who may be subject to liability arising out of any claim in
respect of which indemnity may be sought by the Indemnified Party against the
Indemnifying Party, but the fees and expenses of such counsel shall be for the
account of such Indemnified Party, unless (i) the Indemnifying Party and the
Indemnified Party shall have mutually agreed to the retention of such counsel or
(ii) in the reasonable judgment of the Indemnifying Party and the Indemnified
Party, representation of both parties by the same counsel would be inappropriate
due to actual or potential conflicts of interest between them, it being
understood, however, that the Indemnifying Party shall not, in connection with
any one such claim or action or separate but substantially similar or related
claims or actions in the same jurisdiction arising out of the same general
allegations or circumstances, be liable for the fees and expenses of more than
one separate firm of attorneys (together with appropriate local counsel) at any
time for all Indemnified Parties, or for fees and expenses that are not
reasonable. No Indemnifying Party shall, without the prior written consent of
the Indemnified Party, effect any settlement of any claim or pending or
threatened proceeding in respect of which the Indemnified Party is or could have
been a party and indemnity is sought hereunder by such Indemnified Party, unless
such settlement includes an unconditional release of such Indemnified Party from
all liability arising out of such claim or proceeding. Whether or not the
defense of any claim or action is assumed by the Indemnifying Party, such
Indemnifying Party will not be subject to any liability for any settlement made
without its consent, which consent will not be unreasonably withheld.

     Section 3.3 OTHER INDEMNIFICATION.  Indemnification similar to that
specified in the preceding paragraphs of this Article III (with appropriate
modifications) shall be given by the Company with respect to any required
registration or other qualification of securities under any federal or state law
or regulation of any governmental authority other than the Securities Act. The
provisions of this Article III shall be in addition to any other rights to
indemnification, contribution or other remedies which an Indemnified Party may
have pursuant to law, equity, contract or otherwise.

     Section 3.4 CONTRIBUTION.  If the indemnification and reimbursement
obligations provided for in any section of this Article III is unavailable or
insufficient to hold harmless the Indemnified Parties in respect of any Damages
referred to herein, 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 Damages as between the Company on the one
hand and the Investor on the other, in such proportion as is appropriate to
reflect the relative fault of the Company and of the Investor in connection with
such statements or omissions, as well as other equitable considerations. The
relative fault of the Company on the one hand and of the Investor on the other
shall be determined by reference to, among other things, whether the untrue or
alleged untrue

                                       J-8
<PAGE>   327

statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by such party, and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

     The Company and the Investor agree that it would not be just and equitable
if contribution pursuant to this Section 3.4 were determined by pro rata
allocation or by any other method of allocation that does not take account of
the equitable considerations referred to in the immediately preceding paragraph.
The amount paid or payable by an Indemnified Party as a result of the Damages
referred to in the immediately preceding paragraph shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such Indemnified Party in connection with investigating
or defending any such action or claim. 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.

                                   ARTICLE IV

                                 MISCELLANEOUS

     Section 4.1 NO OUTSTANDING REGISTRATION RIGHTS.  The Company represents and
warrants to the Investor that there is not in effect on the date hereof any
agreement by the Company pursuant to which any holders of securities of the
Company have a right to cause the Company to register or qualify such securities
under the Securities Act or any securities or blue sky laws of any jurisdiction,
except for those warrants issued to investors in February and March 1998 to
purchase shares of Common Stock and warrants to purchase shares of Common Stock
issued to the Company's underwriters in connection with the Company's initial
public offering in September of 1998.

     Section 4.2 TERM.  The obligations of the Company and the rights provided
to the holders of Registrable Securities hereunder shall terminate at such time
as all the Commitment Period has expired and any Registrable Securities
theretofore issued have ceased to be Registrable Securities in accordance with
the definition thereof contained in the Investment Agreement. Notwithstanding
the foregoing, Section 1.1(c) and (d), Article III, Section 4.8, and Section
4.9, shall survive the termination of this Agreement.

     Section 4.3 RULE 144.  The Company will use its commercially reasonable
efforts to file in a timely manner information, documents and reports in
compliance with the Securities Act and the Exchange Act and will, at its
expense, promptly take such further action as holders of Registrable Securities
may reasonably request to enable such holders of Registrable Securities to sell
Registrable Securities without registration under the Securities Act within the
limitation of the exemptions provided by (a) Rule 144 under the Securities Act
("Rule 144"), as such Rule may be amended from time to time, or (b) any similar
rule or regulation hereafter adopted by the SEC. If at any time the Company is
not required to file such reports, it will, at its expense, forthwith upon the
written request of any holder of Registrable Securities, make available adequate
current public information with respect to the Company within the meaning of
paragraph (c)(2) of Rule 144 or such other information as necessary to permit
sales pursuant to Rule 144. Upon the request of the Investor, the Company will
deliver to the Investor a written statement, signed by the Company's principal
executive or financial officer, as to whether it has complied with such
requirements.

                                       J-9
<PAGE>   328

     Section 4.4 CERTIFICATE.  The Company will, at its expense, forthwith upon
the request of any holder of Registrable Securities, deliver to such holder a
certificate, signed by the Company's principal financial officer, stating (a)
the Company's name, address and telephone number (including area code), (b) the
Company's Internal Revenue Service identification number, (c) the Company's SEC
file number, (d) the number of shares of each class of Stock outstanding as
shown by the most recent report or statement published by the Company, and (e)
whether the Company has filed the reports required to be filed under the
Exchange Act for a period of at least ninety (90) days prior to the date of such
certificate and in addition has filed the most recent annual report required to
be filed thereunder.

     Section 4.5 AMENDMENT AND MODIFICATION.  No provision of this Agreement may
be waived, unless such waiver is set forth in a writing executed by both parties
to this Agreement. The provisions of this Agreement, including the provisions of
this sentence, may not be amended, modified or supplemented, and waivers or
consents to departures from the provisions hereof may not be given, unless the
Company has obtained the written consent of the holders of a majority of the
then outstanding Registrable Securities. Notwithstanding the foregoing, the
waiver of any provision hereof with respect to a matter that relates exclusively
to the rights of holders of Registrable Securities whose securities are being
sold pursuant to a Registration Statement and does not directly or indirectly
affect the rights of other holders of Registrable Securities may be given by
holders of at least a majority of the Registrable Securities being sold by such
holders; provided that the provisions of this sentence may not be amended,
modified or supplemented except in accordance with the provisions of the
immediately preceding sentence. No course of dealing between or among any Person
having any interest in this Agreement will be deemed effective to modify, amend
or discharge any part of this Agreement or any rights or obligations of any
person under or by reason of this Agreement.

     Section 4.6 SUCCESSORS AND ASSIGNS; ENTIRE AGREEMENT.  This Agreement and
all of the provisions hereof shall be binding upon and inure to the benefit of
the parties hereto and their respective successors and permitted assigns. The
Investor may assign its rights under this Agreement to any subsequent holder of
the Registrable Securities, provided that the Company shall have the right to
require any holder of Registrable Securities to execute a counterpart of this
Agreement as a condition to such holder's claim to any rights hereunder. This
Agreement, together with the Investment Agreement, sets forth the entire
agreement and understanding between the parties as to the subject matter hereof
and merges and supersedes all prior discussions, agreements and understandings
of any and every nature among them.

     Section 4.7 SEVERABILITY.  In the event that any provision of this
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
effect without said provision; provided that such severability shall be
ineffective if it materially changes the economic benefit of this Agreement to
any party.

     Section 4.8 NOTICES.  All notices, demands, requests, consents, approvals,
and other communications required or permitted hereunder shall be in writing
and, unless otherwise specified herein, shall be (a) personally served, (b)

     creation or imposition of any liens, charges, claims or other encumbrances
     upon the Put Shares, or any of the assets of the Company, or (b) entitle
     the holders of Outstanding Common Stock to preemptive or other rights 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 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
into, or a transfer of all or substantially all of the assets of the Company to,
another entity unless the resulting successor or acquiring entity (if not the
Company) assumes by written instrument the obligation to deliver to Investor
such shares of stock and/or securities as Investor is entitled to receive
pursuant to this Agreement.

     Section 6.11 ISSUANCE OF PUT SHARES.  The sale of the Put Shares shall be
made in accordance with the provisions and requirements of Regulation D and any
applicable state law.

     Section 6.12 LEGAL OPINION ON SUBSCRIPTION DATE.  The Company's legal
counsel shall deliver to Investor upon execution of this Agreement an opinion in
the form of Exhibit C, except for paragraph 7 thereof.

     Section 6.13 LIMITATIONS ON OTHER OFFERINGS BY THE COMPANY.  Until the
earlier of (i) the date twelve months from the date of the first Closing
hereunder, (ii) the termination of this Agreement as provided herein or (iii)
the termination of Investors' obligations under Section 2.5 hereof, neither the
Company nor any of its subsidiaries shall

issue, in any public or private offering, Common Stock or securities convertible
into or exchangeable for Common Stock of the Company ("Common Stock
Equivalents") in which the effective cost per share of the Common Stock to the
purchaser or acquiror thereof would be less than the average of the Average
Daily Prices for a share of Common Stock for the ten Trading Days immediately
preceding the closing of such offering; provided that the Company may so issue
Common Stock or Common Stock Equivalents: (a) in exchange for, or upon
conversion of, any securities convertible into or exchangeable for Common Stock
or Common Stock Equivalents outstanding on the date hereof; (b) pursuant to any
stock option plan, stock purchase plan or similar employee benefit plan in
effect on the date hereof or hereafter adopted by the Company; (c) in any
transaction to which the Investor has given its prior consent (which consent
shall in any case not be unreasonably withheld or delayed), (d) to any entity or
the holders of beneficial interest in such entity in connection with the
acquisition or merger of part or all of such entity or in connection with
proposed joint business efforts between such person or entity and the Company;
(e) in connection with the issuance of debt securities by the Company; (f) in
exchange for bona fide services rendered to the Company; (g) in any offering for
the primary benefit of any person or entity other than the Company such as
Electronic Medical Distribution, Inc. or any other Affiliate of the Company; (h)
any secondary underwritten public offering of Common Stock or other securities
of the Company; or (i) any investment by a strategic investor.

                           CONDITIONS TO DELIVERY OF
                     PUT NOTICES AND CONDITIONS TO CLOSING

     Section 7.1 CONDITIONS PRECEDENT TO THE OBLIGATION OF THE COMPANY TO ISSUE
AND SELL COMMON STOCK.  The obligation hereunder of the Company to issue and
sell the Put Shares to Investor incident to each Closing is subject to the
satisfaction, at or before each such Closing, of each of the conditions set
forth below.

     (a) ACCURACY OF INVESTOR'S REPRESENTATION AND WARRANTIES.  The
representations and warranties of Investor shall be true and correct in all
material respects as of the date of this Agreement and as of the date of each
such Closing as though made at each such time, except for changes which have not
had a Material Adverse Effect.

     (b) PERFORMANCE BY INVESTOR.  Investor shall have performed, satisfied and
complied in all respects with all covenants, agreements and conditions required
by this Agreement to be performed, satisfied or complied with by Investor at or
prior to such Closing.

     Section 7.2 CONDITIONS PRECEDENT TO THE RIGHT OF THE COMPANY TO DELIVER A
PUT NOTICE AND THE OBLIGATION OF INVESTOR TO PURCHASE PUT SHARES.  The right of
the Company to deliver a Put Notice and the obligation of Investor hereunder to
acquire and pay for the Put Shares incident to a Closing is subject to the
satisfaction, on (a) the date of delivery of such Put Notice and (b) the
applicable Closing Date (each a "Condition Satisfaction Date"), of each of the
following conditions:

          (a) REGISTRATION OF REGISTRABLE SECURITIES WITH THE SEC.  As set forth
     in the Registration Rights Agreement, the Company shall have filed with the
     SEC the Initial Registration Statement with respect to the resale of the
     Initial Registrable Securities by Investor and such Registration Statement
     shall have been declared effective by the SEC prior to the first Put Date.
     For the purposes of any Put Notice with respect to the Registrable
     Securities other than the Initial Registrable Securities,

                                      K-15
<PAGE>   350

     the Company shall have filed with the SEC a Registration Statement with
     respect to the resale of such Registrable Securities by Investor which
     shall have been declared effective by the SEC prior to the Put Date
     therefor.

          (b) EFFECTIVE REGISTRATION STATEMENT.  As set forth in the
     Registration Rights Agreement, a Registration Statement shall have
     previously become effective for the resale by Investor of the Registrable
     Securities subject to such Put Notice and such Registration Statement shall
     remain effective on each Condition Satisfaction Date and (i) neither the
     Company nor Investor shall have received notice that the SEC has issued or
     intends to issue a stop order with respect to such Registration Statement
     or that the SEC otherwise has suspended or withdrawn the effectiveness of
     such Registration Statement, either temporarily or permanently, or intends
     or has threatened to do so (unless the SEC's concerns have been addressed
     and Investor is reasonably satisfied that the SEC no longer is considering
     or intends to take such action), and (ii) no other suspension of the use or
     withdrawal of the effectiveness of such Registration Statement or related
     prospectus shall exist.

          (c) ACCURACY OF THE COMPANY'S REPRESENTATIONS AND WARRANTIES.  The
     representations and warranties of the Company shall be true and correct in
     all material respects as of each Condition Satisfaction Date as though made
     at each such time (except for representations and warranties specifically
     made as of a particular date) with respect to all periods, and as to all
     events and circumstances occurring or existing to and including each
     Condition Satisfaction Date, except for any conditions which have
     temporarily caused any representations or warranties herein to be incorrect
     and which have been corrected with no continuing impairment to the Company
     or Investor.

          (d) PERFORMANCE BY THE COMPANY.  The Company shall have performed,
     satisfied and complied in all material respects with all covenants,
     agreements and conditions required by this Agreement and the Registration
     Rights Agreement to be performed, satisfied or complied with by the Company
     at or prior to each Condition Satisfaction Date.

          (e) NO INJUNCTION.  No statute, rule, regulation, executive order,
     decree, ruling or injunction shall have been enacted, entered, promulgated
     or adopted by any court or governmental authority of competent jurisdiction
     that prohibits or directly and materially adversely affects any of the
     transactions contemplated by this Agreement, and no proceeding shall have
     been commenced that may have the effect of prohibiting or materially
     adversely affecting any of the transactions contemplated by this Agreement.

          (f) ADVERSE CHANGES.  Since the date of filing of the Company's most
     recent SEC Document, no event that had or is reasonably likely to have a
     Material Adverse Effect has occurred.

          (g) NO SUSPENSION OF TRADING IN OR DELISTING OF COMMON STOCK.  The
     trading of the Common Stock shall not have been suspended by the SEC, the
     Principal Market or the NASD and the Common Stock shall have been approved
     for listing or quotation on and shall not have been delisted from the
     Principal Market.

          (h) LEGAL OPINION.  The Company shall have caused to be delivered to
     Investor, within five (5) Trading Days of the effective date of the Initial
     Registration

                                      K-16
<PAGE>   351

     Statement and each subsequent Registration Statement, an opinion of the
     Company's legal counsel in the form of Exhibit C hereto, addressed to
     Investor.

          (i) DUE DILIGENCE.  No dispute between the Company and Investor shall
     exist pursuant to Section 7.3 as to the adequacy of the disclosure
     contained in any Registration Statement.

          (j) TEN PERCENT LIMITATION.  On each Closing Date, the number of Put
     Shares then to be purchased by Investor shall not exceed the number of such
     shares that, when aggregated with all other shares of Registrable
     Securities then owned by Investor beneficially or deemed beneficially owned
     by Investor, would result in Investor owning no more than 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 7.2(j), 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 Investor, when aggregating all purchases of Common
     Stock made pursuant to this Agreement would own more than 9.9% of the
     Common Stock following such Closing Date.

          (k) MINIMUM VOLUME AND BID PRICE.  For the ten (10) Trading Days
     immediately preceding both the Put Date and the Closing Date, (a) the
     aggregate Average Daily Trading Volume for each such ten Trading Day period
     shall have equaled or exceeded $500,000 and (b) the average of the Bid
     Prices for such ten Trading Day period shall equal or exceed $7.50 (as
     adjusted for stock splits, stock dividends, reverse stock splits, and
     similar events from and after the date hereof).

          (l) 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).

          (m) TRADING CUSHION.  The Trading Cushion shall have elapsed since the
     immediately preceding Put Date.

          (n) SHAREHOLDER VOTE.  The issuance of shares of Common Stock with
     respect to the applicable Closing, if any, shall not violate the
     shareholder approval requirements of the Principal Market.

          (o) OTHER.  On each Condition Satisfaction Date, Investor shall have
     received and been reasonably satisfied with such other certificates and
     documents as shall have been reasonably requested by Investor in order for
     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 D hereto, executed 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; NON-DISCLOSURE OF NON-PUBLIC INFORMATION.

     (a) The Company shall make available for inspection and review by Investor,
advisors to and representatives of Investor (who may or may not be affiliated
with Investor and who are reasonably acceptable to the Company), any
Underwriter, 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 Investor 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 such Registration Statement for the sole
purpose of enabling Investor 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 such Registration
Statement.

     (b) Each of the Company, its officers, directors, employees and agents
shall in no event disclose non-public information to Investor, advisors to or
representatives of Investor (including, without limitation, in connection with
the giving of the Adjustment Period Notice pursuant to Section 2.4) unless prior
to disclosure of such information the Company identifies such information as
being non-public information and provides Investor, such advisors and
representatives with the opportunity to accept or refuse to accept such
non-public information for review. The Company may, as a condition to disclosing
any non-public information hereunder, require Investor's advisors and
representatives to enter into a confidentiality agreement in form and substance
reasonably satisfactory to the Company and Investor.

     (c) Nothing herein shall require the Company to disclose non-public
information to Investor or its advisors or representatives, and the Company
represents that it does not disseminate 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 shall, as hereinabove provided, immediately notify the
advisors and representatives of Investor and 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 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 a 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 7.3 shall be construed to mean that such
persons or entities other than Investor (without the written consent of Investor
prior to disclosure of such information) may not obtain non-public information
in the course of conducting due diligence in accordance with the terms and
conditions 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, any Registration Statement contains an
untrue statement of a material fact or omits a material fact required to be
stated in such Registration Statement or necessary to make the

                                      K-18
<PAGE>   353

statements contained therein, in light of the circumstances in which they were
made, not misleading.

                                    LEGENDS

     Section 8.1 LEGENDS.  Unless otherwise provided below, each certificate
representing Registrable Securities will bear the following legend (the
"Legend"):

          The securities represented by this certificate have not been
     registered under the Securities Act of 1933 (the "Securities Act") or
     qualified under applicable state securities laws. These securities may not
     be offered, sold, pledged, hypothecated, transferred or otherwise disposed
     of except pursuant to (i) an effective registration statement and
     qualification in effect with respect thereto under the Securities Act and
     under any applicable state securities law, (ii) to the extent applicable,
     Rule 144 under the Securities Act, or (iii) an opinion of counsel
     reasonably acceptable to BioShield Technologies, Inc. that such
     registration and qualification is not required under applicable federal and
     state securities laws.

     As soon as practicable after the execution and delivery hereof, the Company
shall issue to the Transfer Agent instructions in substantially the form of
Exhibit E hereto. Such instructions shall be irrevocable by the Company from and
after the date thereof or from and after the issuance thereof 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 to issue to Investor certificates evidencing shares of Common
Stock incident to a Closing, free of the Legend, 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 Investor; provided that (a) a Registration
Statement shall then be effective, (b) Investor confirms to the Transfer Agent
and the Company that it has or intends to sell such Common Stock to a third
party which is not an affiliate of Investor or the Company and Investor agrees
to redeliver the certificate representing such shares of Common Stock to the
Transfer Agent to add the Legend in the event the Common Stock is not sold, and
(c) if reasonably requested by the transfer agent or the Company, Investor
confirms to the transfer agent and the Company that Investor has complied with
the prospectus delivery requirement under the Securities Act. At any time after
the Effective Date, upon surrender of one or more certificates evidencing Common
Stock 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.

     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 Common Stock 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 Investor's obligations under any agreement to comply with all
applicable securities laws upon resale of the Common Stock.

     Section 9.2 INDEMNIFICATION.

     (a) The Company agrees to indemnify and hold harmless Investor and its
officers, directors, employees, and agents, and each Person or entity, if any,
who controls 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 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 such Damages result primarily from Investor's failure to perform any
covenant or agreement contained in this Agreement or Investor's or its officers,
directors, employees, agents or Controlling Persons negligence, recklessness or
bad faith in performing its obligations under this Agreement.

     (b) Investor agrees to indemnify and hold harmless the Company and its
officers, directors, employees, and agents, and each Person or entity, if any,
who controls Investor within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act, together with the Controlling Persons from and
against any Damages, joint or several, and any action in respect thereof to
which 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 such Damages result primarily from the Company's failure to
perform any covenant or agreement contained in this Agreement or the Company's
or its officers, directors, employees, agents or Controlling Persons negligence,
recklessness or bad faith in performing its obligations under this Agreement.

     Section 9.3 METHOD OF ASSERTING INDEMNIFICATION CLAIMS.  All claims for
indemnification by any Indemnified Party (as defined below) under Section 9.2
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 9.2 (an
     "Indemnified Party") might seek indemnity under Section 9.2 is asserted
     against or sought to be collected from such Indemnified Party by a person
     other than a party hereto or an affiliate thereof (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 that is being asserted under any provision of Section 9.2
     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 prejudiced by such failure of the Indemnified Party. The
     Indemnifying Party shall notify the Indemnified Party as soon as
     practicable within the period ending thirty (30) calendar days following
     receipt by the Indemnifying

                                      K-21
<PAGE>   356

     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 to the Indemnified Party under
     Section 9.2 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 9.3(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 9.2). 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 the sole cost and expense of the Indemnified
        Party, 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; 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 except as provided in the preceding sentence, the Indemnified
        Party shall bear its own costs and expenses with respect to such
        participation. 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 9.2 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 9.3(a), or if the
        Indemnifying Party gives such notice but fails to prosecute vigorously
        and diligently or settle the Third Party Claim, or if the Indemnifying
        Party fails to give any notice whatsoever within the Dispute Period,
        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

                                      K-22
<PAGE>   357

        reasonable cooperation to the Indemnified Party and its counsel in
        contesting any Third Party Claim which the Indemnified Party is
        contesting. Notwithstanding the foregoing provisions of this clause
        (ii), if the Indemnifying Party has notified the Indemnified Party
        within the Dispute Period that the Indemnifying Party disputes its
        liability or the amount of its liability hereunder to the Indemnified
        Party with respect to such Third Party Claim and if such dispute is
        resolved in favor of the Indemnifying Party in the manner provided in
        clause (iii) below, the Indemnifying Party will not be required to bear
        the costs and expenses of the Indemnified Party's defense pursuant to
        this clause (ii) or of the Indemnifying Party's participation therein at
        the Indemnified Party's request, and the Indemnified Party shall
        reimburse the Indemnifying Party in full for all reasonable costs and
        expenses incurred by the Indemnifying Party in connection with such
        litigation. The Indemnifying Party may participate in, but not control,
        any defense or settlement controlled by the Indemnified Party pursuant
        to this clause (ii), and the Indemnifying Party shall bear its own costs
        and expenses with respect to such participation.

             (iii) If the Indemnifying Party notifies the Indemnified Party that
        it does not dispute its liability or the amount of its liability to the
        Indemnified Party with respect to the Third Party Claim under Section
        9.2 or fails to notify the Indemnified Party within the Dispute Period
        whether the Indemnifying Party disputes its liability or the amount of
        its liability to the Indemnified Party with respect to such Third Party
        Claim, the amount of Damages specified in the Claim Notice shall be
        conclusively deemed a liability of the Indemnifying Party under Section
        9.2 and the Indemnifying Party shall pay the amount of such Damages 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;
        provided, however, that it the dispute is not resolved within thirty
        (30) days after the Claim Notice, the Indemnifying Party shall be
        enlisted to institute such legal action as it deems appropriate.

          (b) In the event any Indemnified Party should have a claim under
     Section 9.2 against the Indemnifying Party that does not involve a Third
     Party Claim, the Indemnified Party shall deliver a written notification of
     a claim for indemnity under Section 9.2 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 demonstrates that it has been
     irreparably 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 amount of the claim described in such Indemnity Notice, the
     amount of Damages specified in the Indemnity Notice will be conclusively
     deemed a liability of the Indemnifying Party under Section 9.2 and the
     Indemnifying Party shall pay the amount of such Damages 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

                                      K-23
<PAGE>   358

     proceed in good faith to negotiate a resolution of such dispute; provided,
     however, that it the dispute is not resolved within thirty (30) days after
     the Claim Notice, the Indemnifying Party shall be enlisted to institute
     such legal action as it deems appropriate.

by and interpreted in accordance with the laws of the State of Georgia without
regard to the principles of conflicts of law. Each of the Company and Investor

transactions contemplated hereby or thereby.

     Section 10.2 ASSIGNMENT.  This Agreement shall be binding upon and inure to
the benefit of the Company and Investor and their respective successors and
permitted assigns. Neither this Agreement nor any rights of Investor or the
Company hereunder may be assigned by either party to any other person.
Notwithstanding the foregoing, (a) the provisions of this Agreement shall inure
to the benefit of, and be enforceable by, any transferee of any of the Common
Stock purchased or acquired by Investor hereunder with respect to the Common
Stock held by such person, and (b) Investor's interest in this Agreement may be
assigned at any time, in whole but not in part, to any affiliate of Investor.

     Section 10.3 THIRD PARTY BENEFICIARIES.  This Agreement is intended for the
benefit of the Company and Investor and their respective successors and
permitted assigns, and is not for the benefit of, nor may any provision hereof
be enforced by, any other person.

     Section 10.4 TERMINATION.  This Agreement shall terminate twenty-four (24)
months after the commencement of the Commitment Period (unless extended by the
agreement of the Company and Investor); provided, however, that the provisions
of Article VI, VIII, and Sections 10.1, 10.2, and 10.4 shall survive the
termination of this Agreement.

     Section 10.5 ENTIRE AGREEMENT, AMENDMENT; NO WAIVER.  This Agreement and
the instruments referenced herein contain the entire understanding of the
Company and Investor with respect to the matters covered herein and therein and,
except as specifically set forth herein or therein, neither the Company nor
Investor makes any representation, warranty, covenant or undertaking with
respect to such matters. No provision of this Agreement may be waived or amended
other than by an instrument in writing signed by the party to be charged with
enforcement.

     Section 10.6 FEES AND EXPENSES.  Each of the Company and Investor agrees to
pay its own expenses in connection with the preparation of this Agreement and
performance of its obligations hereunder.

     Section 10.7 NO BROKERS.  Each of the Company and Investor represents that
other than J.P. Carey Securities, Inc. and Greenfield Capital Partners, LLC (the
Company shall be responsible for the fees of such entity) 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 Investor, on the other hand,

                                      K-24
<PAGE>   359

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.

     Section 10.8 COUNTERPARTS.  This Agreement may be executed in multiple
counterparts, each of which may be executed by less than all of the Company and
Investor and shall be deemed to be an original instrument which shall be
enforceable against the parties actually executing such counterparts and all of
which together shall constitute one and the same instrument. This Agreement,
once executed by a party, may be delivered to the other parties hereto by
facsimile transmission of a copy of this Agreement bearing the signature of the
parties so delivering this Agreement.

     Section 10.9 SURVIVAL; SEVERABILITY.  The representations, warranties,
covenants and agreements of the parties hereto shall survive each Closing
hereunder for a period of one year. In the event that any provision of this
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
effect without said provision; provided that such severability shall be
ineffective if it materially changes the economic benefit of this Agreement to
any party.

     Section 10.10 FURTHER ASSURANCES.  Each party shall do and perform, or
cause to be done and performed, all such further acts and things, and shall
execute and deliver all such other agreements, certificates, instruments and
documents, as the other party may reasonably request in order to carry out the
intent and accomplish the purposes of this Agreement and the consummation of the
transactions contemplated hereby.

     Section 10.11 NO STRICT CONSTRUCTION.  The language used in this Agreement
will be deemed to be the language chosen by the parties to express their mutual
intent, and no rules of strict construction will be applied against any party.

     Section 10.12 EQUITABLE RELIEF.  The Company recognizes that in the event
that it fails to perform, observe, or discharge any or all of its obligations
under this Agreement, any remedy at law may prove to be inadequate relief to
Investor. The Company therefore agrees that Investor shall be entitled to
temporary and permanent injunctive relief in any such case without the necessity
of proving actual damages.

     Section 10.13 TITLE AND SUBTITLES.  The titles and subtitles used in this
Agreement are used for the convenience of reference and are not to be considered
in construing or interpreting this Agreement.

     Section 10.14 REPORTING ENTITY FOR THE COMMON STOCK.  The reporting entity
relied upon for the determination of the trading price of the Common Stock on
any given Trading Day for the purposes of this Agreement shall be Bloomberg L.P.
or any successor thereto. The written mutual consent of Investor and the Company
shall be required to employ any other reporting entity.

                         REGISTRATION RIGHTS AGREEMENT

     REGISTRATION RIGHTS AGREEMENT (this "Agreement"), dated as of June 14,
2000, is made and entered into by and between BIOSHIELD TECHNOLOGIES, INC., a
Georgia corporation (the "Company"), and JACKSON, LLC, a Cayman Island limited
liability company (the "Investor").

     WHEREAS, the Company and the Investor have entered into that certain
Private Equity Credit Agreement dated as of the date hereof (the "Investment
Agreement"), pursuant to which the Company may issue and sell, from time to
time, to the Investor up to $50,000,000 worth of shares of its common stock, no
par value per share (the "Common Stock"); and

     WHEREAS, pursuant to the terms of, and in partial consideration for, the
Investor's agreement to enter into the Investment Agreement, the Company has
agreed to provide the Investor with certain registration rights with respect to
the Registrable Securities;

     NOW, THEREFORE, in consideration of the premises, the representations,
warranties, covenants and agreements contained herein and in the Investment
Agreement, and for other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, intending to be legally bound
hereby, the parties hereto agree as follows (capitalized terms used herein and
not defined herein shall have the respective meanings ascribed to them in the
Investment Agreement):

                                   ARTICLE I

                              REGISTRATION RIGHTS

     2.1 REGISTRATION STATEMENTS.

     (a) FILING OF REGISTRATION STATEMENT.  Subject to the terms and conditions
of this Agreement, the Company shall (i) prepare and, within ninety (90) days
following the Subscription Date, deliver to the Investor a draft of a
registration statement on Form S-1 or SB-2 under the Securities Act (the
"Initial Registration Statement") for the registration for the resale by the
Investor of at least 6,666,667 Registrable Securities (the "Initial Registrable
Securities") and accompanied or preceded by a questionnaire (a "Selling
Shareholder Questionnaire") and of the type commonly used for offerings of this
kind and (ii) within ten (10) days after the Company has received comments, if
any, and a properly completed Selling Shareholder Questionnaire from the
Investor, file the Initial Registration Statement with the SEC. Thereafter, if
the Company desires to issue and sell to the Investor any Registrable Securities
in addition to the Initial Registrable Securities, the Company shall first file
with the SEC a registration statement on Form S-1 or Form SB-2 under the
Securities Act (the Initial Registration Statement and any subsequent
registration statement, each a "Registration Statement").

     (b) EFFECTIVENESS OF THE INITIAL REGISTRATION STATEMENT.  The Company shall
use its commercially reasonable efforts (i) to have the Initial Registration
Statement declared effective by the SEC by no later than ninety (90) days after
the filing of the Initial Registration Statement, and (ii) to ensure that the
Initial Registration Statement and any subsequent Registration Statement remains
in effect throughout the term of this Agreement as set forth in Section 4.2,
subject to the terms and conditions of this Agreement.

                                       L-1
<PAGE>   367

     (c) FAILURE TO MAINTAIN EFFECTIVENESS OF A REGISTRATION STATEMENT.  In the
event the Company fails to maintain the effectiveness of any Registration
Statement (or the underlying prospectus) throughout the term of this Agreement
for any period of more than ten (10) continuous calendar days, other than
temporary suspensions permitted by Section 1.1(e), and the Investor holds any
Registrable Securities at any time during the period of such ineffectiveness
(such period of ineffectiveness exceeding such 10 calendar day period being
herein referred to as an "Ineffective Period"), the Company shall pay to the
Investor in immediately available funds into an account designated by the
Investor an amount equal to three percent (3%) of the aggregate Purchase Price
of all of the Registrable Securities then held by the Investor for each ten (10)
calendar day period (prorated for partial periods) of such Ineffective Period.
The payments required by this Section 1.1(d) shall be made on the first Trading
Day after the earliest to occur of (i) the expiration of the Commitment Period,
and (ii) the expiration of an Ineffective Period (or if an Ineffective Period
shall last more than thirty (30) calendar days, the expiration of each thirty
(30) calendar days of an Ineffective Period).

     (d) LIQUIDATED DAMAGES.  The Company and the Investor hereto acknowledge
and agree that the sums payable under subsection 1(c) above shall constitute
liquidated damages and not penalties. The parties further acknowledge that (i)
the amount of loss or damages likely to be incurred is incapable or is difficult
to precisely estimate, (ii) the amounts specified in such subsections bear a
reasonable relationship to, and are not plainly or grossly disproportionate to,
the probable loss likely to be incurred in connection with any failure by the
Company to obtain or maintain the effectiveness of a Registration Statement,
(iii) one of the reasons for the Company and the Investor reaching an agreement
as to such amounts was the uncertainty and cost of litigation regarding the
question of actual damages, and (iv) the Company and the Investor are
sophisticated business parties and have been represented by sophisticated and
able legal counsel and negotiated this Agreement at arm's length.

                                   ARTICLE II

                            REGISTRATION PROCEDURES

     Section 3.1 FILINGS; INFORMATION.  The Company will effect the registration
and sale of the Registrable Securities in accordance with the intended methods
of disposition thereof. Without limiting the foregoing, the Company in each such
case will do the following as expeditiously as possible, but in no event later
than the deadline, if any, prescribed therefor in this Agreement:

          (a) The Company shall (i) prepare and file with the SEC a Registration
     Statement on Form S-1 or SB-2 (if use of such form is then available to the
     Company pursuant to the rules of the SEC and, if not, on such other form
     promulgated by the SEC for which the Company then qualifies, that counsel
     for the Company shall deem appropriate and which form shall be available
     for the sale of the Registrable Securities to be registered thereunder in
     accordance with the provisions of this Agreement and in accordance with the
     intended method of distribution of such Registrable Securities); (ii) use
     commercially reasonable efforts to cause such filed Registration Statement
     to become and remain effective (pursuant to Rule 415 under the Securities
     Act or otherwise); (iii) 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

                                       L-2
<PAGE>   368

     effective for the time period prescribed by Section 1.1(b); and (iv) comply
     with the provisions of the Securities Act with respect to the disposition
     of all securities covered by such Registration Statement during such period
     in accordance with the intended methods of disposition by the Investor set
     forth in such Registration Statement.

          (b) The Company shall file all necessary amendments to any
     Registration Statement in order to effectuate the purpose of this Agreement
     and the Investment Agreement.

          (c) No later than five (5) days prior to filing any amendment or
     supplement to the Initial Registration Statement or any subsequent
     Registration Statement or prospectus, or any amendment or supplement
     thereto (excluding, in each case, amendments deemed to result from the
     filing of documents incorporated by reference therein), or such shorter
     period as is reasonable under the circumstances, the Company shall deliver
     to the Investor and one firm of counsel representing the Investor, in
     accordance with the notice provisions of Section 4.8, copies of such
     Registration Statement as proposed to be filed, together with exhibits
     thereto, which documents will be subject to review by the Investor and such
     counsel, and thereafter deliver to the Investor and such counsel, in
     accordance with the notice provisions of Section 4.8, such number of copies
     of the Registration Statement, each amendment and supplement thereto (in
     each case including all exhibits thereto), the prospectus included in such
     Registration Statement (including each preliminary prospectus) and such
     other documents or information as the Investor or counsel may reasonably
     request in order to facilitate the disposition of the Registrable
     Securities.

          (d) The Company shall deliver, in accordance with the notice
     provisions of Section 4.8, to each seller of Registrable Securities covered
     by a Registration Statement, such number of conformed copies of such
     Registration Statement and of each amendment and supplement thereto (in
     each case including all exhibits and documents incorporated by reference),
     such number of copies of the prospectus contained in any Registration
     Statement (including each preliminary prospectus and any summary
     prospectus) and any other prospectus filed under Rule 424 promulgated under
     the Securities Act relating to such seller's Registrable Securities, and
     such other documents, as such seller may reasonably request to facilitate
     the disposition of its Registrable Securities.

          (e) After the filing of a Registration Statement, the Company shall
     promptly notify the Investor of any stop order issued or threatened by the
     SEC in connection therewith and take all reasonable actions required to
     prevent the entry of such stop order or to remove it if entered.

          (f) The Company shall use its commercially reasonable efforts to (i)
     register or qualify the Registrable Securities under such other securities
     or blue sky laws of such jurisdictions in the United States as the Investor
     may reasonably request in light of its intended plan of distribution and
     (ii) cause the Registrable Securities to be registered with or approved by
     such other governmental agencies or authorities in the United States as may
     be necessary by virtue of the business and operations of the Company, and
     do any and all other acts and things that may be reasonably necessary or
     advisable to enable the Investor to consummate the disposition of the
     Registrable Securities in light of its intended plan of distribution;
     provided, however, that the Company will not be required to qualify
     generally to do business in any jurisdiction where it would not otherwise
     be required to qualify but for this paragraph (f), subject

                                       L-3
<PAGE>   369

     itself to taxation in any such jurisdiction, or consent or subject itself
     to general service of process in any such jurisdiction.

          (g) The Company shall immediately notify the Investor upon the
     occurrence of any of the following events in respect of a Registration
     Statement or related prospectus in respect of an offering of Registrable
     Securities: (i) receipt of any request by the SEC or any other federal or
     state governmental authority for additional information, amendments or
     supplements to such Registration Statement or related prospectus; (ii) the
     issuance by the SEC or any other federal or state governmental authority of
     any stop order suspending the effectiveness of such Registration Statement
     or notification of the initiation of any proceedings for that purpose;
     (iii) receipt of any notification with respect to the suspension of the
     qualification or exemption from 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 such Registration Statement, related prospectus or documents so that, in
     the case of such 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, in the light of the circumstances under which they were made,
     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 such Registration Statement would be
     appropriate, and the Company will promptly make available to the Investor
     any such supplement or amendment to the related prospectus.

          (h) The Company shall enter into customary agreements and take such
     other customary actions as are reasonably required in order to expedite or
     facilitate the disposition by the Investor of such Registrable Securities
     (whereupon the Investor may, at its option, require that any or all of the
     representations, warranties and covenants of the Company also be made to
     and for the benefit of the Investor).

          (i) The Company shall make available to the Investor (and will deliver
     to Investor's counsel), subject to restrictions imposed by the United
     States federal government or any agency or instrumentality thereof, copies
     of all correspondence between the SEC and the Company, its counsel or its
     auditors and will also make available for inspection by the Investor and
     any attorney, accountant or other professional retained by the Investor
     (collectively, the "Inspectors"), all financial and other records,
     pertinent corporate documents and properties of the Company (collectively,
     the "Records") as shall be reasonably necessary to enable them to exercise
     their due diligence responsibility, and cause the Company's officers and
     employees to supply all information reasonably requested by any Inspectors
     in connection with a Registration Statement. Records that the Company
     determines, in good faith, to be confidential and that it notifies the
     Inspectors are confidential shall not be disclosed by the Inspectors unless
     (i) the disclosure of such Records is necessary to avoid or correct a
     misstatement or omission in any Registration Statement or (ii) the
     disclosure or release of such Records is requested or required

                                       L-4
<PAGE>   370

     pursuant to oral questions, interrogatories, requests for information or
     documents or a subpoena or other order from a court of competent
     jurisdiction or other legal process; provided, however, that prior to any
     disclosure or release pursuant to clause (ii), the Inspectors shall provide
     the Company with prompt notice of any such request or requirement so that
     the Company may seek an appropriate protective order or waive such
     Inspectors' obligation not to disclose such Records; and, provided,
     further, that if failing the entry of a protective order or the waiver by
     the Company permitting the disclosure or release of such Records, the
     Inspectors, upon advice of counsel, are compelled to disclose such Records,
     the Inspectors may disclose that portion of the Records that counsel has
     advised the Inspectors that the Inspectors are compelled to disclose. The
     Investor agrees that information obtained by it as a result of such
     inspections (not including any information obtained from a third party who,
     insofar as is known to the Investor after reasonable inquiry, is not
     prohibited from providing such information by a contractual, legal or
     fiduciary obligation to the Company) shall be deemed confidential and shall
     not be used by it as the basis for any market transactions in the
     securities of the Company unless and until such information has been made
     generally available to the public. The Investor further agrees that it
     will, upon learning that disclosure of such Records is sought in a court of
     competent jurisdiction, give notice to the Company and allow the Company,
     at its expense, to undertake appropriate action to prevent disclosure of
     the Records deemed confidential.

          (j) The Company shall otherwise comply with all applicable rules and
     regulations of the SEC, including, without limitation, compliance with
     applicable reporting requirements under the Exchange Act.

          (k) The Company may require the Investor to promptly furnish in
     writing to the Company such information as may be legally required in
     connection with such registration including, without limitation, all such
     information as may be requested by the SEC or the NASD. The Investor agrees
     to provide such information requested in connection with such registration
     within five (5) calendar days after receiving such written request, or such
     shorter period as is reasonable under the circumstances, and the Company
     shall not be responsible for any delays in obtaining or maintaining the
     effectiveness of any Registration Statement caused by the Investor's
     failure to timely provide such information.

     Section 3.2 SECTION REGISTRATION EXPENSES.  In connection with each
Registration Statement, the Company shall pay all registration expenses incurred
in connection with the registration thereunder (the "Registration Expenses"),
including, without limitation: (a) all registration, filing, securities exchange
listing and fees required by the NASD, (b) all registration, filing,
qualification and other fees and expenses of compliance with securities or blue
sky laws (including reasonable fees and disbursements of counsel for the
Company), (c) all word-processing, duplicating, printing, messenger and delivery
expenses, (d) the Company's internal expenses (including, without limitation,
all salaries and expenses of its officers and employees performing legal or
accounting duties), and (e) reasonable fees and disbursements of counsel for the
Company and customary fees and expenses for independent certified public
accountants retained by the Company.

                        INDEMNIFICATION AND CONTRIBUTION

     Section 4.1 INDEMNIFICATION.

     a. To the fullest extent permitted by law, the Company will, and hereby
does, indemnify, hold harmless and defend each Investor who holds such
Registrable Securities, the directors, officers, partners, employees, agents and
each Person, if any, who controls any Investor within the meaning of the 1933
Act or the Securities Exchange Act of 1934, as amended (the "1934 Act")
(collectively, Controlling Person"), and any underwriter (as defined in the 1933
Act) for the Investors, and the directors and officers of, and each Person, if
any, who controls, any such underwriter within the meaning of the 1933 Act or
the 1934 Act (each, an "Indemnified Person"), against any losses, claims,
damages, liabilities, judgments, fines, penalties, charges, costs, attorneys'
fees, amounts paid in settlement or expenses, joint or several, (collectively,
"Claims") incurred in investigating, preparing or defending any action, claim,
suit, inquiry, proceeding, investigation or appeal taken from the foregoing by
or before any court or governmental, administrative or other regulatory agency,
body or the SEC, whether pending or threatened, whether or not an indemnified
party is or may be a party thereto ("Indemnified Damages"), to which any of them
may become subject insofar as such Claims (or actions or proceedings, whether
commenced or threatened, in respect thereof) arise out of or are based upon: (i)
any untrue statement or alleged untrue statement of a material fact in a
Registration Statement or any post-effective amendment thereto or in any filing
made in connection with the qualification of the offering under the securities
or other "blue sky" laws of any jurisdiction in which Registrable Securities are
offered ("Blue Sky Filing"), or the omission or alleged omission to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which the statements therein were
made, not misleading, (ii) any untrue statement or alleged untrue statement of a
material fact contained in any preliminary prospectus if used prior to the
effective date of such Registration Statement, or contained in the final
prospectus (as amended or supplemented, if the Company files any amendment
thereof or supplement thereto with the SEC) or the omission or alleged omission
to state therein any material fact necessary to make the statements made
therein, in light of the circumstances under which the statements therein were
made, not misleading, or (iii) any violation or alleged violation by the Company
of the 1933 Act, the 1934 Act, any other law, including, without limitation, any
state securities law, or any rule or regulation thereunder relating to the offer
or sale of the Registrable Securities pursuant to a Registration Statement (the
matters in the foregoing clauses (i) through (iii) being, collectively,
"Violations"). Subject to the restrictions set forth herein with respect to the
number of legal counsel, the Company shall reimburse the Investors and each such
underwriter or controlling person, promptly as such expenses are incurred and
are due and payable, for any legal fees or other reasonable expenses incurred by
them in connection with investigating or defending any such Claim.
Notwithstanding anything to the contrary contained herein, the indemnification
agreement contained in this Section: (i) shall not apply to a Claim arising out
of or based upon a Violation which occurs in reliance upon and in conformity
with information furnished in writing to the Company by any Indemnified Person
or underwriter for such Indemnified Person expressly for use in connection with
the preparation of the Registration Statement or any such amendment thereof or
supplement thereto, if such prospectus was timely made available by the Company
pursuant to Section 3(c); (ii) with respect to any preliminary prospectus, shall
not inure to the benefit of an y such person from whom the person asserting any
such Claim purchased the Registrable Securities that are the subject thereof (or
to the benefit

                                       L-6
<PAGE>   372

of any person controlling such person) if the untrue statement or mission of
material fact contained in the preliminary prospectus was corrected in the
prospectus, as then amended or supplemented, if such prospectus was timely made
available by the Company pursuant to Section 3(c), and the Indemnified Person
was promptly advised in writing not to use the incorrect prospectus prior to the
use giving rise to a violation and such Indemnified Person, notwithstanding such
advice, used it; (iii) shall not be available to the extent such Claim is based
on a failure of the Investor to deliver or to cause to be delivered the
prospectus made available by the Company (i) and (iv) shall not apply to amounts
paid in settlement of any Claim if such settlement is effected without the prior
written consent of the Company, which consent shall not be unreasonably
withheld. Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of the Indemnified Person and shall survive
the transfer of the Registrable Securities by the Investors pursuant to Section
9.

     b. In connection with any Registration Statement in which an Investor is
participating, each such Investor agrees to severally and not jointly indemnify,
hold harmless and defend, to the same extent and in the same manner as is set
forth herein, the Company, each of its directors, each of its officers who signs
the Registration Statement, each Person, if any, who controls the Company within
the meaning of the 1933 Act or the 1934 Act (collectively and together with an
Indemnified Person, an "Indemnified Party"), against any Claim or Indemnified
Damages to which any of them may become subject, under the 1933 Act, the 1934
Act or otherwise, insofar as such Claim or Indemnified Damages arise out of or
are based upon any Violation, in each case to the extent, and only to the
extent, that such Violation occurs in reliance upon and in conformity with
written information furnished to the Company by such Investor expressly for use
in connection with such Registration Statement; and, subject to Section 6(d),
such Investor will reimburse any legal or other expenses reasonably incurred by
them in connection with investigating or defending any such Claim; provided,
however, that the indemnity agreement contained in this Section shall not apply
to amounts paid in settlement of any Claim if such settlement is effected
without the prior written consent of such Investor, which consent shall not be
unreasonably withheld. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of such Indemnified Party
and shall survive the transfer of the Registrable Securities by the Investors.
Notwithstanding anything to the contrary contained herein, the indemnification
agreement contained in this Section with respect to any preliminary prospectus
shall not inure to the benefit of any Indemnified Party if the untrue statement
or omission of material fact contained in the preliminary prospectus was
corrected on a timely basis in the prospectus, as then amended or supplemented.

     c. The Company shall be entitled to receive indemnities from underwriters,
selling brokers, dealer managers and similar securities industry professionals
participating in any distribution, to the same extent as provided above, with
respect to information such persons so furnished in writing expressly for
inclusion in the Registration Statement.

     d. Promptly after receipt by an Indemnified Person or Indemnified Party
under this Section of notice of the commencement of any action or proceeding
(including any governmental action or proceeding) involving a Claim such
Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is
to be made against any indemnifying party under this Section 6, deliver to the
indemnifying party a written notice of the commencement thereof, and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other

                                       L-7
<PAGE>   373

indemnifying party similarly noticed, to assume control of the defense thereof
with counsel mutually satisfactory to the indemnifying party and the Indemnified
Person or the Indemnified Party, as the case may be; provided, however, that an
Indemnified Person or Indemnified Party shall have the right to retain its own
counsel with the fees and expenses to be paid by the indemnifying party, if, in
the reasonable opinion of counsel retained by the indemnifying party, the
representation by such counsel of the Indemnified Person or Indemnified Party
and the indemnifying party would be inappropriate due to actual or potential
differing interests between such Indemnified Person or Indemnified Party and any
other party represented by such counsel in such proceeding. The Company shall
pay reasonable fees for only one separate legal counsel for the Investors, which
counsel shall be acceptable to the Company and such legal counsel shall be
selected by the Investors holding a majority in interest of the Registrable
Securities included in the Registration Statement to which the Claim relates.
The Indemnified Party or Indemnified Person shall cooperate fully with the
indemnifying party in connection with any negotiation or defense of any such
action or claim by the indemnifying party and shall furnish to the indemnifying
party all information reasonably available to the Indemnified Party or
Indemnified Person which relates to such action or claim. The indemnifying party
shall keep the Indemnified Party or Indemnified Person fully apprised at all
times as to the status of the defense or any settlement negotiations with
respect thereto. No indemnifying party shall be liable for any settlement of any
action, claim or proceeding effected without its written consent, provided,
however, that the indemnifying party shall not unreasonably withhold, delay or
condition its consent. No indemnifying party shall, without the consent of the
Indemnified Party or Indemnified Person, consent to entry of any judgment or
enter into any settlement or other compromise which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party or Indemnified Person of a release from all liability in
respect to such claim or litigation. Following indemnification as provided for
hereunder, the indemnifying party shall be subrogated to all rights of the
Indemnified Party or Indemnified Person with respect to all third parties, firms
or corporations relating to the matter for which indemnification has been made.
The failure to deliver written notice to the indemnifying party within a
reasonable time of the commencement of any such action shall relieve such
indemnifying party of any liability to the Indemnified Person or Indemnified
Party under this Section 6.

     e. The indemnity agreements contained herein shall be in addition to (i)
any cause of action or similar right of the Indemnified Party or Indemnified
Person against the indemnifying party or others, and (ii) any liabilities the
indemnifying party may be subject to pursuant to the law.

     f. To the extent any indemnification by an indemnifying party is prohibited
or limited by law, the indemnifying party agrees to make the maximum
contribution with respect to any amounts for which it would otherwise be liable
under this Section to the fullest extent permitted by law; provided, however,
that: (i) no contribution shall be made under circumstances where the maker
would not have been liable for indemnification under the fault standards set
forth in this Section; (ii) no seller of Registrable Securities guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933
Act) shall be entitled to contribution from any seller of Registrable Securities
who was not guilty of fraudulent misrepresentation; and (iii) contribution by
any seller of Registrable Securities shall be limited in amount to the net
amount of proceeds received by such seller from the sale of such Registrable
Securities.

                                 MISCELLANEOUS

     Section 5.1 NO OUTSTANDING REGISTRATION RIGHTS.  The Company represents and
warrants to the Investor that there is not in effect on the date hereof any
agreement by the Company pursuant to which any holders of securities of the
Company have a right to cause the Company to register or qualify such securities
under the Securities Act or any securities or blue sky laws of any jurisdiction,
except for those disclosed in the Company's public filings.

     Section 5.1 TERM.  The obligations of the Company and the rights provided
to the holders of Registrable Securities hereunder shall terminate at such time
as all the Commitment Period has expired and any Registrable Securities
theretofore issued have ceased to be Registrable Securities in accordance with
the definition thereof contained in the Investment Agreement. Notwithstanding
the foregoing, Section 1.1(c) and (d), Article III, Section 4.8, and Section
4.9, shall survive the termination of this Agreement.

     Section 5.2 RULE 144.  The Company will use its commercially reasonable
efforts to file in a timely manner information, documents and reports in
compliance with the Securities Act and the Exchange Act and will, at its
expense, promptly take such further action as holders of Registrable Securities
may reasonably request to enable such holders of Registrable Securities to sell
Registrable Securities without registration under the Securities Act within the
limitation of the exemptions provided by (a) Rule 144 under the Securities Act
("Rule 144"), as such Rule may be amended from time to time, or (b) any similar
rule or regulation hereafter adopted by the SEC. If at any time the Company is
not required to file such reports, it will, at its expense, forthwith upon the
written request of any holder of Registrable Securities, make available adequate
current public information with respect to the Company within the meaning of
paragraph (c)(2) of Rule 144 or such other information as necessary to permit
sales pursuant to Rule 144. Upon the request of the Investor, the Company will
deliver to the Investor a written statement, signed by the Company's principal
executive or financial officer, as to whether it has complied with such
requirements.

     Section 5.3 CERTIFICATE.  The Company will, at its expense, forthwith upon
the request of any holder of Registrable Securities, deliver to such holder a
certificate, signed by the Company's principal financial officer or other
executive officer, stating (a) the Company's name, address and telephone number
(including area code), (b) the Company's Internal Revenue Service identification
number, (c) the Company's SEC file number, (d) the number of shares of each
class of Stock outstanding as shown by the most recent report or statement
published by the Company, and (e) whether the Company has filed the reports
required to be filed under the Exchange Act for a period of at least ninety (90)
days prior to the date of such certificate and in addition has filed the most
recent annual report required to be filed thereunder.

     Section 5.4 AMENDMENT AND MODIFICATION.  No provision of this Agreement may
be waived, unless such waiver is set forth in a writing executed by both parties
to this Agreement. The provisions of this Agreement, including the provisions of
this sentence, may not be amended, modified or supplemented, and waivers or
consents to departures from the provisions hereof may not be given, unless the
Company has obtained the written consent of the holders of a majority of the
then outstanding Registrable Securities. Notwithstanding the foregoing, the
waiver of any provision hereof with respect to a matter that relates exclusively
to the rights of holders of Registrable Securities whose securities

                                       L-9
<PAGE>   375

are being sold pursuant to a Registration Statement and does not directly or
indirectly affect the rights of other holders of Registrable Securities may be
given by holders of at least a majority of the Registrable Securities being sold
by such holders; provided that the provisions of this sentence may not be
amended, modified or supplemented except in accordance with the provisions of
the immediately preceding sentence. No course of dealing between or among any
Person having any interest in this Agreement will be deemed effective to modify,
amend or discharge any part of this Agreement or any rights or obligations of
any person under or by reason of this Agreement.

     Section 5.5 SUCCESSORS AND ASSIGNS; ENTIRE AGREEMENT.  This Agreement and
all of the provisions hereof shall be binding upon and inure to the benefit of
the parties hereto and their respective successors and permitted assigns. The
Investor may assign its rights under this Agreement to any subsequent holder of
the Registrable Securities, provided that the Company shall have the right to
require any holder of Registrable Securities to execute a counterpart of this
Agreement as a condition to such holder's claim to any rights hereunder. This
Agreement, together with the Investment Agreement, sets forth the entire
agreement and understanding between the parties as to the subject matter hereof
and merges and supersedes all prior discussions, agreements and understandings
of any and every nature among them.

     Section 5.6 SEVERABILITY.  In the event that any provision of this
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
effect without said provision; provided that such severability shall be
ineffective if it materially changes the economic benefit of this Agreement to
any party.

                               WARRANT AGREEMENT

     WARRANT AGREEMENT dated as of June 14, 2000, between BioShield
Technologies, Inc., a Delaware corporation (the "Company"), and Jackson LLC, a
Cayman Island limited liability company (hereinafter referred to as "Investor").

                              W I T N E S S E T H:

     WHEREAS, Investor has entered into a Private Equity Agreement (the
"Investment Agreement") with the Company pursuant to which the Investor may
purchase up to $50,000,000 of shares of common stock, no par value, of the
Company (the "Common Stock"); and

     WHEREAS, the Warrants issued pursuant to this Agreement are being issued by
the Company to Investor and/or its designees, in consideration for, and as part
of the investment by Investor in connection with the Investment Agreement;

     NOW, THEREFORE, in consideration of the premises, the agreements herein set
forth and other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties hereto agree as follows (capitalized
terms used herein without definition shall have the meanings ascribed to then in
the Investment Agreement):

     1. GRANT.

     Investor and/or its designees are hereby granted the right to purchase, at
any time from the date of the closing of the first purchase by Investor of
shares of Common Stock pursuant to the Investment Agreement (the "Initial
Closing") until 5:00 P.M., Eastern Standard Time, on the fifth anniversary of
the Initial Closing (the "Warrant Exercise Term"), 250,000 Shares of Common
Stock (the "Shares") at an exercise price (subject to adjustment as provided in
Article 7 hereof) equal to $18.92 (the "Initial Exercise Price").

     2. WARRANT CERTIFICATES.

     The warrant certificates (the "Warrant Certificates") delivered and to be
delivered pursuant to this Agreement shall be in the form set forth as Exhibit
A, attached hereto and made a part hereof, with such appropriate insertions,
omissions, substitutions and other variations as required or permitted by this
Agreement.

     3. EXERCISE OF WARRANTS.

     3.1 CASH EXERCISE.  The Exercise Price may be paid in cash or by check to
the order of the Company, or any combination of cash or check, subject to
adjustment as provided in Article 7 hereof. Upon surrender of the Warrant
Certificate with the annexed Form of Election to Purchase duly executed,
together with payment of the Exercise Price (as hereinafter defined) for the
Shares purchased, at the Company's executive offices currently located at 5655
Peachtree Parkway Atlanta, Georgia 30092, the registered holder of a Warrant
Certificate ("Holder" or "Holders") shall be entitled to receive a certificate
or certificates for the Shares so purchased. The purchase rights represented by
each Warrant Certificate are exercisable at the option of the Holder hereof, in
whole or in part (but not as to fractional shares of the Common Stock). In the
case of the purchase of less than all

                                       M-1
<PAGE>   379

the Shares purchasable under any Warrant Certificate, the Company shall cancel
said Warrant Certificate upon the surrender thereof and shall execute and
deliver a new Warrant Certificate of like tenor for the balance of the Shares
purchasable thereunder.

     3.2 CASHLESS EXERCISE.  At any time during the Warrant Exercise Term, the
Holder may, at its option, exchange this Warrant, in whole or in part (a
"Warrant Exchange"), into the number of Shares determined in accordance with
this Section 3.2, by surrendering this Warrant at the principal office of the
company or at the office of its transfer agent, accompanied by a notice stating
such Holder's intent to effect such exchange, the number of Shares to be
exchanged and the date on which the Holder requests that such Warrant Exchange
occur (the "Notice of Exchange"). The Warrant Exchange shall take place on the
date specified in the Notice of Exchange or, if later, the date the Notice of
Exchange is received by the Company (the "Exchange Date"). Certificates for the
Shares issuable upon such Warrant Exchange and, if applicable, a new warrant of
like tenor evidencing the balance of the Shares remaining subject to this
Warrant, shall be issued as of the Exchange Date and delivered to the Holder
within seven (7) business days following the Exchange Date. In connection with
any Warrant Exchange, this Warrant shall represent the right to subscribe for
and acquire the number of Shares (rounded to the next highest integer) equal to
(i) the number of Shares specified by the Holder in its Notice of Exchange (the
"Total Number") less (ii) the number of Shares equal to the quotient obtained by
dividing (A) the product of the Total Number and the then existing Exercise
Price by (B) the average of the Closing Prices for the five Trading Days
immediately prior to the date specified in the Notice of Exchange.

     3.3 EXERCISE LIMITATION.  In no event shall any Investor be entitled to
exercise any of the warrants if, upon the exercise of such warrant(s), it would
cause the aggregate number of shares of Common Stock beneficially owned by the
Investor and its affiliates to exceed 4.9% of the outstanding shares of the
Common Stock following such exercise.

     4. ISSUANCE OF CERTIFICATES.

     Upon the exercise of the Warrants, the issuance of certificates for the
Shares shall be made forthwith (and in any event within five business days
thereafter) without charge to the Holder thereof including, without limitation,
any tax which may be payable in respect of the issuance thereof, and such
certificates shall be issued in the name of, or in such names as may be directed
by, the Holder thereof; provided, however, that the Company shall not be
required to pay any tax which may be payable in respect of any transfer involved
in the issuance and delivery of any such certificates in a name other than that
of the Holder and the Company shall not be required to issue or deliver such
certificates unless or until the person or persons requesting the issuance
thereof shall have paid to the Company the amount of such tax or shall have
established to satisfaction of the Company that such tax has been paid.

     The Warrant Certificates and the certificates representing the Shares shall
be executed on behalf of the Company by the manual or facsimile signature of the
present or any future Chairman or Vice Chairman of the Board of Directors, Chief
Executive officer or President or Vice President of the Company under its
corporate seal reproduced thereon, attested to by the manual or facsimile
signature of the present or any future Secretary or Assistant Secretary of the
Company. Warrant Certificates shall be dated the date of execution by the
Company upon initial issuance, division, exchange, substitution or transfer.

                                       M-2
<PAGE>   380

     The Warrant Certificates and, upon exercise of the Warrants, in part or in
whole, certificates representing the Shares shall bear a legend substantially
similar to the following:

          The securities represented by this certificate have not been
     registered under the Securities Act of 1933, as amended (the "Act"), and
     may not be offered or sold except (i) pursuant to an effective registration
     statement under the Act, (ii) to the extent applicable, pursuant to Rule
     144 under the Act (or any similar rule under such Act relating to the
     disposition of securities), or (iii) upon the delivery by the holder to the
     Company of an opinion of counsel, satisfactory to counsel to the issuer,
     stating that an exemption from registration under such Act is available.

     5. PRICE.

     5.1 ADJUSTED EXERCISE PRICE.  The adjusted Exercise Price shall be the
price which shall result from time to time from any and all adjustments of the
Initial Exercise Price in accordance with the provisions of Article 7 hereof.

     5.2 EXERCISE PRICE.  The term "Exercise Price" herein shall mean the
Initial Exercise Price or the adjusted Exercise Price, depending upon the
context.

     6. REGISTRATION RIGHTS.

     6.1 REGISTRATION UNDER THE SECURITIES ACT OF 1993.

     The Warrants and the Shares have not been registered for purposes of public
distribution under the Securities Act of 1933, as amended ("the Act").

     6.2 REGISTRABLE SECURITIES.  As used herein the term "Registrable Security"
means each of the Warrants, the Shares and any shares of Common Stock issued
upon any stock split or stock dividend in respect of such Shares; provided,
however, that with respect to any particular Registrable Security, such security
shall cease to be a Registrable Security when, as of the date of determination,
(i) it has been effectively registered under the Securities Act and disposed of
pursuant thereto, (ii) registration under the Securities Act is no longer
required for the immediate public distribution of such security or (iii) it has
ceased to be outstanding. The term "Registrable Securities" means any and/or all
of the securities falling within the foregoing definition of a "Registrable
Security." In the event of any merger, reorganization, consolidation,
recapitalization or other change in corporate structure affecting the Common
Stock, such adjustment shall be made in the definition of "Registrable Security"
as is appropriate in order to prevent any dilution or enlargement of the rights
granted pursuant to this Article 6.

     6.3 PIGGYBACK REGISTRATION.  If, at any time during the five years
following the date of the Initial Closing, the Company proposes to prepare and
file any registration statement or post-effective amendments (other than in
connection with an underwritten initial public offering or initial registration
of the Company or the Company's securities with the U.S. Securities & Exchange
Commission) thereto covering equity or debt securities of the Company, or any
such securities of the Company held by its shareholders (in any such case, other
than in connection with a merger, acquisition or pursuant to Form S-8 or
successor form), (for purposes of this Article 6, collectively, a "Registration
Statement"), it will give written notice of its intention to do so by registered
mail ("Notice"), at ten (10) business days prior to the filing of each such
Registration Statement, to all holders of the Registrable Securities. Upon the
written request of such a holder (a "Requesting Holder"), made within ten (10)
business days after receipt of the Notice, that the

                                       M-3
<PAGE>   381

Company include any of the Requesting Holder's Registrable Securities in the
proposed Registration Statement, the Company shall, as to each such Requesting
Holder, use its best efforts to effect the registration under the Securities Act
of the Registrable Securities which it has been so requested to register
("Piggyback Registration"), at the Company's sole cost and expense and at no
cost or expense to the Requesting Holders. Notwithstanding the provisions of
this Section 6.3, the Company shall have the right at any time after it shall
have given written notice pursuant to this Section 6.3 (irrespective of whether
any written request for inclusion of such securities shall have already been
made) to elect not to file any such proposed Registration Statement, or to
withdraw the same after the filing but prior to the effective date thereof.

     7. ADJUSTMENTS OF EXERCISE PRICE AND NUMBER OF SHARES.

     7.1 SUBDIVISION AND COMBINATION.  In case the Company shall at any time
subdivide or combine the outstanding shares of Common Stock, the Exercise Price
shall forthwith be proportionately decreased in the case of subdivision or
increased in the case of combination.

     7.2 ADJUSTMENT IN NUMBER OF SHARES.  Upon each adjustment of the Exercise
Price pursuant to the provisions of this Article 7, the number of Shares
issuable upon the exercise of each Warrant shall be adjusted to the nearest full
Share by multiplying a number equal to the Exercise Price in effect immediately
prior to such adjustment by the number of Shares issuable upon exercise of the
Warrants immediately prior to such adjustment and dividing the product so
obtained by the adjusted Exercise Price.

     7.3 RECLASSIFICATION, CONSOLIDATION, MERGER, ETC.  In case of any
reclassification or change of the outstanding shares of Common Stock (other than
a change in par value to no par value, or from no par value to par value, or as
a result of a subdivision or combination), or in the case of any consolidation
of the Company with, or merger of the Company into, another corporation (other
than a consolidation or merger in which the Company is the surviving corporation
and which does not result in any reclassification or change of the outstanding
shares of Common Stock, except a change as a result of a subdivision or
combination of such shares or a change in par value, as aforesaid), or in the
case of a sale or conveyance to another corporation of the property of the
Company as an entirety, the Holders shall thereafter have the right to purchase
the kind and number of shares of stock and other securities and property
receivable upon such reclassification, change, consolidation, merger, sale or
conveyance as if the Holders were the owners of the shares of Common Stock
underlying the Warrants immediately prior to any such events at a price equal to
the product of (x) the number of shares issuable upon exercise of the Warrants
and (y) the Exercise Price in effect immediately prior to the record date for
such reclassification, change, consolidation, merger, sale or conveyance as if
such Holders had exercised the Warrants.

     7.4 NO ADJUSTMENT OF EXERCISE PRICE IN CERTAIN CASES.  No adjustment of the
Exercise Price shall be made:

          (a) Upon the issuance or sale of shares of Common Stock upon the
     exercise of the Warrants; or

          (b) Upon (i) the issuance of options pursuant to the Company's
     employee stock option plans in effect or the issuance or sale by the
     Company of any shares of Common Stock pursuant to the exercise of any such
     options, or (ii) the issuance or

                                       M-4
<PAGE>   382

     sale by the Company of any shares of Common Stock pursuant to the exercise
     of any options or warrants; or

          (c) Upon the issuance of shares of Common Stock pursuant to
     contractual obligations; or

          (d) If the amount of said adjustment shall be less than 2 cents (2c)
     per Share, provided, however, that in such case any adjustment that would
     otherwise be required then to be made shall be carried forward and shall be
     made at the time of and together with the next subsequent adjustment which,
     together with any adjustment so carried forward, shall amount to at least 2
     cents (2c) per Share.

     8. EXCHANGE AND REPLACEMENT OF WARRANT CERTIFICATES.

     Each Warrant Certificate is exchangeable without expense, upon the
surrender hereof by the registered Holder at the principal executive office of
the Company, for a new Warrant Certificate of like tenor and date representing
in the aggregate the right to purchase the same number of Shares in such
denominations as shall be designated by the Holder thereof at the time of such
surrender.

     Upon receipt by the Company of evidence reasonably satisfactory to it of
the loss, theft, destruction or mutilation of any Warrant Certificate, and, in
case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to it, and reimbursement to the Company of all reasonable expenses
incidental thereto, and upon surrender and cancellation of the Warrants, if
mutilated, the Company will make and deliver a new Warrant Certificate of like
tenor, in lieu thereof.

     9. ELIMINATION OF FRACTIONAL INTERESTS.

     The Company shall not be required to issue certificates representing
fractions of shares of Common Stock and shall not be required to issue scrip or
pay cash in lieu of fractional interests, it being the intent of the parties
that all fractional interests shall be eliminated by rounding any fraction up to
the nearest whole number of shares of Common Stock.

     10. RESERVATION AND LISTING OF SECURITIES.

     The Company shall at all times reserve and keep available out of its
authorized shares of Common Stock, solely for the purpose of issuance upon the
exercise of the Warrants, such number of shares of Common Stock as shall be
issuable upon the exercise thereof. The Company covenants and agrees that, upon
exercise of the Warrants and payment of the Exercise Price therefor, all shares
of Common Stock issuable upon such exercise shall be duly and validly issued,
fully paid, nonassessable and not subject to the preemptive rights of any
shareholder. As long as the Warrants shall be outstanding, the Company shall use
its best efforts, once it has become a public company, to cause all shares of
Common Stock issuable upon the exercise of the Warrants to be listed on or
quoted on the electronic bulletin board, by NASDAQ or listed on such national
securities exchanges.

     11. NOTICES TO WARRANT HOLDERS.

     Nothing contained in this Agreement shall be construed as conferring upon
the Holder or Holders the right to vote or to consent or to receive notice as a
shareholder in respect of any meetings of shareholders for the election of
directors or any other matter, or as having any rights whatsoever as a
shareholder of the Company. If, however, at any time

                                       M-5
<PAGE>   383

prior to the expiration of the Warrants and their exercise, any of the following
events shall occur:

          (a) the Company shall take a record of the holders of its shares of
     Common Stock for the purpose of entitling them to receive a dividend or
     distribution payable otherwise than in cash, or a cash dividend or
     distribution payable otherwise than out of current or retained earnings, as
     indicated by the accounting treatment of such dividend or distribution on
     the books of the Company; or

          (b) a dissolution, liquidation or winding up of the Company (other
     than in connection with a consolidation or merger) or a sale of all or
     substantially all of its property, assets and business as an entirety shall
     be proposed;

then, in any one or more of said events, the Company shall give written notice
of such event at least fifteen (15) days prior to the date fixed as a record
date or the date of closing the transfer books for the determination of the
shareholders entitled to such dividend, distribution, convertible or
exchangeable securities or subscription rights, options or warrants, or entitled
to vote on such proposed dissolution, liquidation, winding up or sale. Such
notice shall specify such record date or the date of closing the transfer books,
as the case may be. Failure to give such notice or any defect therein shall not
affect the validity of any action taken in connection with the declaration or
payment of any such dividend or distribution, or any proposed dissolution,
liquidation, winding up or sale.

     12. NOTICES.

     All notices, requests, consents and other communications hereunder shall be

by registered or certified mail, return receipt requested:

          (a) If to a registered Holder of the Warrants, to the address of such
     Holder as shown on the books of the Company; or

          (b) If to the Company, to the address set forth in Section 3 of this
     Agreement or to such other address as the Company may designate by notice
     to the Holders.

     13. SUPPLEMENTS AND AMENDMENTS.

     The Company may from time to time supplement or amend this Agreement
without the approval of any Holders of Warrant Certificates in order to cure any
ambiguity, to correct or supplement any provision contained herein which may be
defective or inconsistent with any provisions herein, or to make any other
provisions in regard to matters or questions arising hereunder which the Company
may deem necessary or desirable and which the Company deems not to adversely
affect the interests of the Holders of Warrant Certificates.

     14. SUCCESSORS.

     All the covenants and provisions of this Agreement by or for the benefit of
the Company and the Holders inure to the benefit of their respective successors
and assigns hereunder.

     15. TERMINATION.

anniversary of the Initial Closing. Notwithstanding the foregoing, this
Agreement will terminate on any

                                       M-6
<PAGE>   384

earlier date when all Warrants have been exercised and all the Shares issuable
upon exercise of the Warrants have been resold to the public; provided, however,
that the provisions of Article 6 shall survive such termination until the close
of business on fifth anniversary of the Initial Closing.

     16. GOVERNING LAW.

     This Agreement and each Warrant Certificate hereunder shall be governed by
and interpreted in accordance with the laws of the State of Georgia without
regard to the principles of conflict of laws. The parties further agree that any
action between them shall be heard in Atlanta, Georgia, and expressly consent to
the jurisdiction and venue of the Superior Court of Fulton County, Georgia, and
the United States District Court for the Northern District of Georgia, Atlanta
Division for the adjudication of any civil action asserted pursuant to this
Paragraph.

     17. BENEFITS OF THIS AGREEMENT.

     Nothing in this Agreement shall be construed to give to any person or
corporation other than the Company and the Investor and any other registered
holder or holders of the Warrant Certificates, Warrants or the Shares any legal
or equitable right, remedy or claim under this Agreement; and this Agreement
shall be for the sole and exclusive benefit of the Company and the Investor and
any other holder or holders of the Warrant Certificates, Warrants or the Shares.

     18. COUNTERPARTS.

     This Agreement may be executed in any number of counterparts and each of
such counterparts shall for all purposes be deemed to be an original, and such
counterparts shall together constitute but one and the same instrument.

                                       M-7

                           ARTICLES OF INCORPORATION
                                       OF
                          BIOSHIELD TECHNOLOGIES, INC.

                                       I.

     The name of the corporation is BioShield Technologies, Inc. (the
"Corporation").

                                      II.

     Effective as of the date hereof, Article[II] of the Articles of
Incorporation, as amended is amended to read in full as follows: The Corporation
hereby designates that the total number of shares of capital stock which the
Corporation has authority to issue is 50,000,000, divided into 40,000,000 shares
of "Common Stock," no par value, and 10,000,000 shares of capital stock, no par
value, to be designated as "Preferred Stock."

                                      III.

     The Corporation hereby designates 500 of the 10,000,000 authorized shares
of its Preferred Stock as "Series B Convertible Preferred Stock," no par value
(the "Preferred Stock") and shall possess the rights and privileges set forth
below:

          (1) DIVIDENDS.  The Series B Preferred Shares shall not bear any
     dividends.

          (2) HOLDER'S CONVERSION OF SERIES B PREFERRED SHARES.  A holder of
     Series B Preferred Shares shall have the right, at such holder's option, to
     convert the Series B Preferred Shares into shares of the Company's common
     stock, no par value per share (the "Common Stock"), on the following terms
     and conditions:

             (a) CONVERSION RIGHT.  Subject to the provisions of Sections 2(j)
        and 3(a) below, at any time or times on or after the earlier to occur of
        (i) 90 days after the Issuance Date (as defined herein) or (ii) the date
        that Registration Statement filed by the Company registering the Common
        Stock to be issued upon conversion of the Preferred Stock is declared
        effective (the "Effective Date") by the U.S. Securities and Exchange
        Commission (the "SEC"), any holder of Series B Preferred Shares shall be
        entitled to convert any Series B Preferred Shares into fully paid and
        non-assessable shares (rounded to the nearest whole share in accordance
        with Section 2(h) below) of Common Stock, at the Conversion Rate (as
        defined below); provided, however, that in no event other than upon a
        Mandatory Conversion pursuant to Section 2(f) hereof, shall any holder
        be entitled to convert Series B Preferred Shares in excess of that
        number of Series B Preferred Shares which, upon giving effect to such
        conversion, would cause the aggregate number of shares of Common Stock
        beneficially owned by the holder and its affiliates to exceed 4.9% of
        the outstanding shares of the Common Stock following such conversion.
        For purposes of the foregoing proviso, the aggregate number of shares of
        Common Stock beneficially owned by the holder and its affiliates shall
        include the number of shares of Common Stock issuable upon conversion of
        the Series B Preferred

                                       N-1
<PAGE>   392

        Shares with respect to which the determination of such proviso is being
        made, but shall exclude the number of shares of Common Stock which would
        be issuable upon conversion of the remaining, nonconverted Series B
        Preferred Shares beneficially owned by the holder and its affiliates.
        Except as set forth in the preceding sentence, for purposes of this
        paragraph, beneficial ownership shall be calculated in accordance with
        Section 13(d) of the Securities Exchange Act of 1934, as amended.

             (b) CONVERSION RATE.  The number of shares of Common Stock issuable
        upon conversion of each of the Series B Preferred Shares pursuant to
        Section (2)(a) shall be determined according to the following formula
        (the "Conversion Rate");

                         (.05)(N/365)(20,000) + 20,000
                      ------------------------------------

                  (iii) "Floating Conversion Price" means, as of any date of
             determination, the amount obtained by multiplying the Conversion
             Percentage in effect as of such date by the lowest Average Market

             ten (10) consecutive Trading Days immediately preceding such date;

                  (v) "Average Market Price" means, with respect to any security

             arithmetic average of the Closing Bid Prices and Closing Ask Prices
             (as defined below) for such security for each Trading Day in such
             period;

                  (vi) "Closing Ask Price" means, for any security as of any
             date, the last closing ask price on the Nasdaq SmallCap Market (the

             market for such security, the last closing ask price of such
             security on the principal securities exchange or trading market
             where such security is listed or traded as reported by Bloomberg
             (the "Trading Market"), or if the foregoing do not apply, the last
             closing ask price of such security in the over-the-counter market

             security by Bloomberg, the last closing ask price of such security
             as reported by Bloomberg. If the Closing Ask Price cannot be
             calculated for such security on such date on any of the foregoing
             bases, the Closing Ask Price of such security on such date shall be
             the fair market value as reasonably determined in good faith by the
             Board of Directors of the Company all as appropriately adjusted for
             any stock dividend, stock split or other similar transaction during
             such period; and

                                       N-2

             market for such security, the last closing bid price of such
             security on the principal securities exchange or trading market

             security by Bloomberg, the last closing trade price of such
             security as reported by Bloomberg. If the Closing Bid Price cannot
             be calculated for such security on such date on any of the

             date shall be the fair market value as reasonably determined in
             good faith by the Board of Directors of the Company (all as
             appropriately adjusted for any stock dividend, stock split or other
             similar transaction during such period).

             registered with the SEC at the election of the Company. In the
             event that the Company elects to pay the Coupon in cash, the
             formula used to calculate the Conversion Rate shall be adjusted to
             exclude the calculation of the Coupon.

                  (ix) "N" means the number of days from, but excluding, the
             Issuance Date through and including the Conversion Date for the

             (c) ADJUSTMENT TO CONVERSION PRICE -- DILUTION AND OTHER

        Amendment, the Conversion Price will be subject to adjustment from time
        to time as provided in this Section 2(d).

                  (i) REORGANIZATION, RECLASSIFICATION, CONSOLIDATION, MERGER,

             Common Stock are entitled to receive (either directly or upon
             subsequent liquidation) stock, securities or assets with respect to
             or in exchange for Common Stock is referred to herein as in
             "Organic Change." Prior to the consummation of any Organic Change,
             the Company will make appropriate provision to insure that each of
             the holders of the Series B Preferred Shares will thereafter have
             the right to acquire and receive in lieu of or in addition to (as
             the case may be) the shares of Common Stock immediately theretofore
             acquirable and receivable upon the conversion of

                                       N-3
<PAGE>   394

             such holder's Series B Preferred Shares, such shares of stock,
             securities or assets as may be issued or payable with respect to or
             in exchange for the number of shares of Common Stock immediately
             theretofore acquirable and receivable upon the conversion of such
             holder's Series B Preferred Shares had such Organic Change not
             taken place. In any such case, the Company will make appropriate
             provision (in form and substance satisfactory to the holders of a
             majority of the Series B Preferred Shares then outstanding) with
             respect to such holders' rights and interests to insure that the
             provisions of this Section 2(c) will thereafter be applicable to
             the Series B Preferred Shares. The Company will not effect any such
             consolidation, merger or sale, unless prior to the consummation
             thereof the successor entity (if other than the Company) resulting
             from consolidation or merger or the entity purchasing such assets
             assumes, by written instrument (in form and substance satisfactory
             to the holders of a majority of the Series B Preferred Shares then
             outstanding), the obligation to deliver to each holder of Series B
             Preferred Shares such shares of stock, securities or assets as, in
             accordance with the foregoing provisions, such holder may be
             entitled to acquire. For purposes of this Agreement, "Person" shall
             mean an individual, a limited liability company, a partnership, a
             joint venture, a corporation, a trust, an unincorporated
             organization and a government or any department or agency thereof.

                  (ii) NOTICES.

                       (A) Immediately upon any adjustment of the Conversion
                  Price, the Company will give written notice thereof to each
                  holder of Series B Preferred Shares, setting forth in
                  reasonable detail and certifying the calculation of such
                  adjustment.

                       (B) The Company will also give written notice to each
                  holder of Series B Preferred Shares at least twenty (20) days
                  prior to the date on which any Organic Change (as defined
                  below), dissolution or liquidation will take place.

             (d) MECHANICS OF CONVERSION.  Subject to the Company's inability to
        fully satisfy its obligations under a Conversion Notice (as defined
        below) as provided for in Section 5 below:

             for delivery to the Company or the Transfer Agent as soon as
             practicable following such date, the original certificates
             representing the Series B Preferred Shares being converted (or an
             indemnification undertaking with respect to such shares in the case
             of their loss, theft or destruction) (the "Preferred Stock
             Certificates") and the originally executed Conversion Notice.

                  (ii) COMPANY'S RESPONSE.  Upon receipt by the Company of a
             facsimile copy of a Conversion Notice, the Company shall
             immediately send, via Facsimile, a confirmation of receipt of such
             Conversion Notice to such holder. Upon receipt by the Company or
             the Transfer Agent of the Preferred Stock Certificates to be
             converted pursuant to a Conversion Notice, together with the
             originally executed Conversion Notice, the Company or the Transfer
             Agent (as applicable) shall, within five (5) business days
             following the date of receipt, (A) issue and surrender to a common
             carrier for overnight delivery to the address as specified in the
             Conversion Notice, a certificate, registered in the name of the
             holder or its designee, for the number of shares of Common Stock to
             which the holder shall be entitled or (B) credit the aggregate
             number of shares of Common Stock to which the holder shall be
             entitled to the holder's or its designee's balance account at The
             Depository Trust Company.

                  (iii) DISPUTE RESOLUTION.  In the case of a dispute as to the
             determination of the Average Market Price or the arithmetic
             calculation of the Conversion Rate, the Company shall promptly
             issue to the holder the number of shares of Common Stock that is
             not disputed and shall submit the disputed determinations or
             arithmetic calculations to the holder via facsimile within three
             (3) business days of receipt of such holder's Conversion Notice. If
             such holder and the Company are unable to agree upon the
             determination of the Average Market Price or arithmetic calculation
             of the Conversion Rate within three (3) business days of such
             disputed determination or arithmetic calculation being submitted to
             the holder, then the Company shall within one (1) business day
             submit via facsimile (A) the disputed determination of the Average
             Market Price to an independent, reputable investment bank or (B)
             the disputed arithmetic calculation of the Conversion Rate to its
             independent, outside accountant. The Company shall cause the
             investment bank or the accountant, as the case may be, to perform
             the determinations or calculations and notify the Company and the
             holder of the results no later than forty-eight (48) hours from the
             time it receives the disputed determinations or calculations. Such
             investment bank's or accountant's determination or calculation, as
             the case may be, shall be binding upon all parties absent manifest
             error.

                  (iv) RECORD HOLDER.  The person or persons entitled to receive
             the shares of Common Stock issuable upon a conversion of Series B
             Preferred Shares shall be treated for all purposes as the record
             holder or holders of such shares of Common Stock on the Conversion
             Date.

             (e) NASDAQ LISTING.  So long as the Common Stock is listed for
        trading on Nasdaq-SM or an exchange or quotation system with a rule
        substantially similar to Rule 4460(i) then, notwithstanding anything to
        the contrary contained herein if, at any time, the aggregate number of
        shares of Common Stock then issued upon conversion of the Series B
        Preferred Shares (including any shares of capital stock or rights to
        acquire shares of capital stock issued by the Corporation which are
        aggregated or integrated with the Common Stock issued or issuable upon
        conversion of the Series B Preferred Shares for purposes of such rule)
        equals 19.99% of the "Outstanding Common Amount" (as hereinafter
        defined), the Series B Preferred Shares shall, from that time forward,
        cease to be

                                       N-5
<PAGE>   396

        convertible into Common Stock in accordance with the terms hereof,
        unless the Corporation (i) has obtained approval of the issuance of the
        Common Stock upon conversion of the Series B Preferred Shares by a
        majority of the total votes cast on such proposal, in person or by
        proxy, by the holders of the then-outstanding Common Stock (not
        including any shares of Common Stock held by present or former holders
        of Series B Preferred Shares that were issued upon conversion of Series
        B Preferred Shares (the "Stockholder Approval"), or (ii) shall have
        otherwise obtained permission to allow such issuances from Nasdaq in
        accordance with Nasdaq Rule 4460(i). If the Corporation's Common Stock
        is not then listed on Nasdaq or an exchange or quotation system that has
        a rule substantially similar to Rule 4460(i) then the limitations set
        forth herein shall be inapplicable and of no force and effect. For
        purposes of this paragraph, "Outstanding Common Amount" means (i) the
        number of shares of the Common Stock outstanding on the date of issuance
        of the Series B Preferred Shares pursuant to the Purchase Agreement plus
        (ii) any additional shares of Common Stock issued thereafter in respect
        of such shares pursuant to a stock dividend, stock split or similar
        event. The maximum number of shares of Common Stock issuable as a result
        of the 19.99% limitation set forth herein is hereinafter referred to as
        the "Maximum Share Amount." With respect to each holder of Series B
        Preferred Shares, the Maximum Share Amount shall refer to such holder's
        pro rata share thereof. In the event that Corporation obtains
        Stockholder Approval or the approval of Nasdaq, or by reason of the
        inapplicability of the rules of Nasdaq or otherwise, the Corporation
        concludes that it is able to increase the number of shares to be issued
        above the Maximum Share Amount (such increased number being the "New
        Maximum Share Amount"), the references to Maximum Share Amount, above,
        shall be deemed to be, instead, references to the greater New Maximum
        Share Amount. In the event that Stockholder Approval is obtained and
        there are insufficient reserved or authorized shares, or a registration
        statement covering the additional shares of Common Stock which
        constitute the New Maximum Share Amount is not effective prior to the
        Maximum Share Amount being issued (if such registration statement is
        necessary to allow for the public resale of such securities), the
        Maximum Share Amount shall remain unchanged; provided, however, that the
        holders of Series B Preferred Shares may grant an extension to obtain a
        sufficient reserved or authorized amount of shares or of the effective
        date of such registration statement. In the event that (a) the aggregate
        number of shares of Common Stock actually issued upon conversion of the
        outstanding Series B Preferred Shares represents at least twenty percent
        (20%) of the Maximum Share Amount and (b) the sum of (x) the aggregate
        number of shares of Common Stock issued upon conversion of Series B
        Preferred Shares plus (y) the aggregate number of shares of Common Stock
        that remain issuable upon conversion of Series B Preferred Shares and
        based on the Conversion Price then in effect), represents at least one
        hundred percent (100%) of the Maximum Share Amount, the Corporation will
        use its best reasonable efforts to seek and obtain Stockholder Approval
        (or obtain such other relief as will allow conversions hereunder in
        excess of the Maximum Share Amount) as soon as practicable following the
        Triggering Event and before the Mandatory Redemption Date.

             (f) MANDATORY CONVERSION.  If any Series B Preferred Shares remain
        outstanding on June 14, 2003, then all such Series B Preferred Shares
        shall be converted as of such date in accordance with this Section 2 as
        if the holders of

                                       N-6
<PAGE>   397

        such Series B Preferred Shares had given the Conversion Notice on June
        14, 2003, and the Conversion Date had been fixed as of June 14, 2003,
        (the "Mandatory Conversion Date") for all purposes of this Section 2,
        and all holders of Series B Preferred Shares shall thereupon and within
        two (2) business days thereafter surrender all Preferred Stock
        Certificates, duly endorsed for cancellation, to the Company or the
        Transfer Agent. No person shall thereafter have any rights in respect of
        Series B Preferred Shares, except the right to receive shares of Common
        Stock on conversion thereof as provided in this Section 2.

             (g) FRACTIONAL SHARES.  The Company shall not issue any fraction of
        a share of Common Stock upon any conversion. All shares of Common Stock
        (including fractions thereof) issuable upon conversion of more than one
        share of the Series B Preferred Shares by a holder thereof shall be
        aggregated for purposes of determining whether the conversion would
        result in the issuance of a fraction of a share of Common Stock. If,
        after the aforementioned aggregation, the issuance would result in the
        issuance of a fraction of a share of Common Stock, the Company shall
        round such fraction of a share of Common Stock up or down to the nearest
        whole share.

             (h) TAXES.  The Company shall pay any and all taxes which may be
        imposed upon it with respect to the issuance and delivery of Common
        Stock upon the conversion of the Series B Preferred Shares.

             (i) LOCK-UP.  [INTENTIONALLY LEFT BLANK]

          (3) COMPANY'S RIGHT TO REDEEM AT ITS ELECTION.

             (a) At any time after the Effective Date, the Company shall have
        the right, in its sole discretion, to redeem ("Redemption at Company's
        Election"), from time to time, any or all of the Series B Preferred
        Shares; provided (i) Company shall first provide twenty-five (25)
        Trading Days advance written notice as provided in subparagraph 3(a)(ii)
        below, and (ii) that the Company shall only be entitled to redeem Series
        B Preferred Shares having an aggregate Stated Value (as defined below)
        of at least Five Hundred Thousand Dollars ($500,000). If the Company
        elects to redeem some, but not all, of the Series B Preferred Shares,
        the Company shall redeem a pro-rata amount from each holder of the
        Series B Preferred Shares.

                  (i) REDEMPTION PRICE AT COMPANY'S ELECTION.  The "Redemption
             Price at Company's Election" shall be calculated as 125% of the
             Stated Value. For purposes hereof, "Stated Value" shall mean the
             original purchase price of Preferred Stock being redeemed plus any
             accrued and unpaid coupon due thereunder.

                  (ii) MECHANICS OF REDEMPTION AT COMPANY'S ELECTION.  The
             Company shall effect each such redemption by giving at least twenty
             five (25) Trading Days prior written notice ("Notice of Redemption
             at Company's Election") to (A) the holders of the Series B
             Preferred Shares selected for redemption at the address and
             facsimile number of such holder appearing in the Company's Series B
             Preferred Shares register and (B) the Transfer Agent, which Notice
             of Redemption At Company's Election shall be deemed to have been
             delivered three (3) business days after the Company's mailing (by
             overnight or two (2) day courier, with a copy by facsimile) of such

                                       N-7
<PAGE>   398

             Notice of Redemption at Company's Election. Such Notice of
             Redemption At Company's Election shall indicate (i) the number of
             shares of Series B Preferred Shares that have been selected for
             redemption, (ii) the date which such redemption is to become
             effective (the "Date of Redemption At Company's Election") and
             (iii) the applicable Redemption Price At Company's Election, as
             defined in subsection (a)(i) above. Notwithstanding the above, the
             holder may convert into Common Stock, prior to the close of
             business on the Date of Redemption at Company's Election, any
             Series B Preferred Shares which it is otherwise entitled to
             convert, including Series B Preferred Shares that has been selected
             for redemption at Company's election pursuant to this subsection
             3(a).

             (b) COMPANY MUST HAVE IMMEDIATELY AVAILABLE FUNDS OR CREDIT
        FACILITIES. The Company shall not be entitled to send any Redemption
        Notice and begin the redemption procedure under Section 3(a) unless it
        has:

                  (i) the full amount of the redemption price to cash, available
             in a demand or other immediately available account in a bank or
             similar financial institution; or

                  (ii) immediately available credit facilities, in the full
             amount of the redemption price with a bank or similar financial
             institution, or

                  (iii) an agreement with a standby underwriter willing to
             purchase from the Company a sufficient number of shares of stock to
             provide proceeds necessary to redeem any stock that is not
             converted prior to redemptions; or

                  (iv) a combination of the items set forth in (i), (ii), and
             (iii) above, aggregating the full amount of the redemption price.

             (c) PAYMENT OF REDEMPTION PRICE.  Each holder submitting Series B
        Preferred Shares being redeemed under this Section 3 shall send their
        Preferred Stock Certificates to redeemed to the Company or its Transfer
        Agent, and the Company shall pay the applicable redemption price to that
        Holder within five (5) business days of the Date of Redemption at
        Company's Election. If the Company fails to pay the Redemption Price,
        the redemption right provided in this section shall be declared null and
        void. However, this redemption right shall not be null and void if a
        bona fide dispute exists with respect to the calculation of the
        Redemption Price.

          (4) REISSUANCE OF CERTIFICATES.  In the event of a conversion or
     redemption pursuant to this Amendment of less than all of the Series B
     Preferred Shares represented by a particular Preferred Stock Certificate,
     the Company shall promptly cause to be issued and delivered to the holder
     of such Series B Preferred Shares a Preferred Stock Certificate
     representing the remaining Series B Preferred Shares which have not been so
     converted or redeemed.

          (5) RESERVATION OF SHARES.  The Company shall, so long as any of the
     Series B Preferred Shares are outstanding reserve and keep available out of
     its authorized and unissued Common Stock, solely for the purpose of
     effecting the conversion of the Series B Preferred Shares, such number of
     shares of Common Stock as shall from time to time be sufficient to affect
     the conversion of all of the Series B Preferred Shares then outstanding;
     provided that the number of shares of Common Stock so

                                       N-8
<PAGE>   399

     reserved shall at no time be less than 100% of the number of shares of
     Common Stock for which the Series B Preferred Shares are at any time
     convertible,

          (6) VOTING RIGHTS.  Holders of Series B Preferred Shares shall have no
     voting rights, except as required by law, including but not limited to the
     Corporation Law of the State of Georgia and as expressly provided in this
     Amendment.

          (7) LIQUIDATION, DISSOLUTION, WINDING-UP.  In the event of any
     voluntary or involuntary liquidation, dissolution, or winding up of the
     Company, the holders of the Series B Preferred Shares shall be entitled to
     receive in cash out of the assets of the Company, whether from capital or
     from earnings available for distribution to its stockholders (the
     "Preferred Funds"), before any amount shall be paid to the holders of any
     of the capital stock of the Company of any class junior in rank to the
     Series B Preferred Shares in respect of the preferences as to the
     distributions and payments on the liquidation, dissolution and winding up
     of the Company, an amount per Series B Preferred Share equal to the sum of
     (i) $20,000 and (ii) an amount equal to the product of (.05) (N/365)
     ($20,000) (where "N" has the meaning specified in Section 2(b)(viii); (such
     sum being referred to as the "Liquidation Value"); provided that, if the
     Preferred Funds are insufficient to pay the full amount due to the holders
     of Series B Preferred Shares and holders of shares of other classes or
     series of preferred stock of the Company that are of equal rank with the
     Series B Preferred Shares as to payments of Preferred Funds (the "Pari
     Passu Shares"), then each holder of Series B Preferred Shares and Pari
     Passu Shares shall receive a percentage of the Preferred Funds equal to the
     full amount of Preferred Funds payable to such holder as a liquidation
     preference, in accordance with their respective preferences and rights, as
     a percentage of the full amount of Preferred Funds payable to all holders
     of Series B Preferred Shares and Pari Passu Shares. The purchase or
     redemption by the Company of stock of any class in any manner permitted by
     law, shall not for the purposes hereof, be regarded as a liquidation,
     dissolution or winding up of the Company. Neither the consolidation or
     merger of the Company with or into any other Person, nor the sale or
     transfer by the Company of less than substantially all of its assets,
     shall, for the purposes hereof, be deemed to be a liquidation, dissolution
     or winding up of the Company. No holder of Series B Preferred Shares shall
     be entitled to receive any amounts with respect thereto upon any
     liquidation, dissolution or winding up of the Company other than the
     amounts provided for herein.

          (8) PREFERRED RATE.  All shares of Common Stock shall be of junior
     rank to all Series B Preferred Shares in respect to the preferences as to
     distributions and payments upon the liquidation, dissolution, and winding
     up of the Company. The Series B Preferred Shares shall be of greater than
     any Series of Common or Preferred Stock hereinafter issued by the Company.
     Without the prior express written consent of the holders of not less than a
     majority of the then outstanding Series B Preferred Shares, the Company
     shall not hereafter authorize or issue additional or other capital stock
     that is of senior or equal rank to the Series B Preferred Shares in respect
     of the preferences as to distributions and payments upon the liquidation,
     dissolution and winding up of the Company. Without the prior express
     written consent of the holders of not less than a majority of the then
     outstanding Series B Preferred Shares, the Company shall not hereafter
     authorize or make any amendment to the Company's Articles of Incorporation
     or bylaws, or make any resolution of the board of directors with the
     Georgia Secretary of State containing any provisions, which would
     materially and adversely affect or otherwise impair the rights or relative
     priority of the holders of

                                       N-9
<PAGE>   400

     the Series B Preferred Shares relative to the holders of the Common Stock
     or the holders of any other class of capital stock. In the event of the
     merger or consolidation of the Company with or into another corporation,
     the Series B Preferred Shares shall maintain their relative powers,
     designations, and preferences provided for herein and no merger shall
     result inconsistent therewith.

          (9) RESTRICTION ON DIVIDENDS.  Other than the distribution of the
     securities of the Company to the Company's shareholders, if any Series B
     Preferred Shares are outstanding, without the prior express written consent
     of the holders of not less than a majority of the then outstanding Series B
     Preferred Shares, the Company shall not directly or indirectly declare, pay
     or make any dividends or other distributions upon any of the Common Stock
     so long as written notice thereof has been given to holders of the Series B
     Preferred Shares at least 30 days prior to the earlier of (a) the record
     date taken for or (b) the payment of any such dividend or other
     distribution. Notwithstanding the foregoing, this Section 9 shall not
     prohibit the Company from declaring and paying a dividend in cash with
     respect to the Common Stock so long as the Company: (i) pays simultaneously
     to each holder of Series B Preferred Shares an amount in cash equal to the
     amount such holder would have received had all of such holder's Series B
     Preferred Shares been converted to Common Stock pursuant to Section 2
     hereof one business day prior to the record date for any such dividend, and
     (ii) after giving effect to the payment of any dividend and any other
     payments required in connection therewith including to the holders of the
     Series B Preferred Shares, the Company has in cash or cash equivalents an
     amount equal to the aggregate of: (A) all of its liabilities reflected on
     its most recently available balance sheet, (B) the amount of any
     indebtedness incurred by the Company or any of its subsidiaries since its
     most recent balance sheet and (C) 120% of the amount payable to all holders
     of any shares of any class of preferred stock of the Company assuming a
     liquidation of the Company as the date of its most recently available
     balance sheet.

          (10) VOTE TO CHANGE THE TERMS OF SERIES B PREFERRED SHARES.  The
     affirmative vote at a meeting duly called for such purpose, or the written
     consent without a meeting of the holders of not less than a majority of the
     then outstanding Series B Preferred Shares, shall be required for any
     change to this Amendment or the Company's Articles of Incorporation which
     would amend, alter, change or repeal any of the powers, designations,
     preferences and rights of the Series B Preferred Shares.

          (11) LOST OR STOLEN CERTIFICATES.  Upon receipt by the Company of
     evidence satisfactory to the Company of the loss, theft, destruction or
     mutilation of any Preferred Stock Certificates representing the Series B
     Preferred Shares, and, in the case of loss, theft or destruction, of any
     indemnification undertaking by the holder to the Company and, in the case
     of mutilation, upon surrender and cancellation of the Preferred Stock
     Certificate(s), the Company shall execute and deliver new preferred stock
     certificate(s) of like tenor and date; provided, however, the Company shall
     not be obligated to re-issue preferred stock certificates if the holder
     contemporaneously requests the Company to convert such Series B Preferred
     Shares into Common Stock.

          (12) WITHHOLDING TAX OBLIGATIONS.  Notwithstanding anything herein to
     the contrary, to the extent that the Company receives advice in writing
     from its counsel that there is a reasonable basis to believe that the
     Company is required by applicable federal laws or regulations and delivers
     a copy of such written advice to the holders of the Series B Preferred
     Shares so effected, the Company may reasonably condition the making of any
     distribution (as such term is defined under applicable federal tax law

                                      N-10
<PAGE>   401

     and regulations) in respect of any Series B Preferred Share on the holder
     of such Series B Preferred Shares depositing with the Company an amount of
     cash sufficient to enable the Company to satisfy its withholding tax
     obligations (the "Withholding Tax") with respect to such distribution.
     Notwithstanding the foregoing or anything to the contrary, if any holder of
     the Series B Preferred Shares so effected receives advice in writing from
     its counsel that there is a reasonable basis to believe that the Company is
     not so required by applicable federal laws or regulations and delivers a
     copy of such written advice to the Company, the Company shall not be
     permitted to condition the making of any such distribution in respect of
     any Series B Preferred Share on the holder of such Series B Preferred
     Shares depositing with the Company any Withholding Tax with respect to such
     distribution, provided, however, the Company may reasonably condition the

                                               BIOSHIELD TECHNOLOGIES, INC.

                                                FORM OF LOCK-UP AGREEMENT

     Reference is made to the Amendments to the Articles of Incorporation (the
"Amendment") of BioShield Technologies, Inc. (the "Company"). The undersigned
has been advised that in accordance with and pursuant to Section (2)(i) of the
Amendment, effective as of                (the "Lock-Up Commencement Date"), the
Company has elected to exercise its Lock-Up rights (as set forth in the
Amendment) with respect to shares of Series B Convertible Preferred Stock (the
"Series B Preferred Shares"), no par value per share. Consequently, the Company
shall not be required to convert any Series B Preferred Shares which have a
Conversion Date (as defined in the Amendment) during the period (the "Lock-Up
Period") beginning on the Lock-Up Commencement Date and ending on the earlier of
(i) that date which is ninety (90) days from the Lock-Up Commencement Date and
(ii) the 725th day following the Issuance Date (as defined in the Amendment).

     In consideration of the agreement by the holders of the Series B Preferred
Shares not to convert any Series B Preferred Share pursuant to the Lock-Up
rights, and for other good and valuable consideration, the undersigned hereby
irrevocably agrees that, until one day after each of the holders of the Series B
Preferred Shares has received written notice form the Company that the Lock-Up
Period has ended, the undersigned will not, directly or indirectly, without the
prior written consent of the holders representing a majority of the outstanding
Series B Preferred Shares, sell, contact to sell, pledge, grant any option for
the sale of or otherwise dispose or cause the disposition of any shares of the
Company's common stock, no par value per share (the "Common Stock"), or an
securities convertible into or exchangeable or exercisable for any shares of
Common Stock owned by the undersigned. Notwithstanding the foregoing, the
undersigned shall not need to obtain such written consent with respect to (1) a
transfer (not involving a sale in the public market) of shares of Common Stock
by the undersigned in a bona fide charitable or other donative transaction or in
any estate planning transaction so long as in each case the transferee of such
agreement to holders of the Series B Preferred Shares prior to effecting any
such transfer and (2) a transfer (not involving a sale in the public market) of
shares of Common Stock, if the undersigned is a natural person, due to the death
or disability of the undersigned so long as the transferee of such shares agrees
in writing to be bound by the terms of this agreement and furnishes a copy of
such agreement to holders of the Series B Preferred Shares prior to effecting
any such transfer.

     In furtherance of the foregoing, the Company and the Company's transfer
agent and registrar are hereby authorized to decline to make any transfer or
securities if such transfer would constitute a violation or breach of this
agreement.

                                          Very truly yours,

                               WARRANT AGREEMENT

     WARRANT AGREEMENT dated as of June 15, 2000, between BioShield
Technologies, Inc., a Delaware corporation (the "Company"), and Wilson LLC, a
Cayman Island limited liability company (hereinafter referred to as "Investor").

                              W I T N E S S E T H:

     WHEREAS, Investor has participated as an Investor in connection with the
Company's offering (the "Offering") of up to $10,000,000 of the Company's Series
B Convertible Preferred Stock, no par value (the "Preferred Stock"); and

     WHEREAS, the Warrants issued pursuant to this Agreement are being issued by
the Company to Investor and/or its designees, in consideration for, and as part
of the investment by Investor in connection with the Offering;

     NOW, THEREFORE, in consideration of the premises, the agreements herein set
forth and other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties hereto agree as follows (capitalized
terms used herein without definition shall have the meanings ascribed to then in
the Offering):

     1. GRANT.

     Investor and/or its designees are hereby granted the right to purchase, at
any time from the date of the closing of the first purchase by Investor of
shares of common stock, no par value (the "Common Stock") pursuant to the
Offering (the "Initial Closing") until 5:00 P.M., Eastern Standard Time, on the
fifth anniversary of the Initial Closing (the "Warrant Exercise Term"), 79,281
Shares of Common Stock (the "Shares") at an exercise price (subject to
adjustment as provided in Article 7 hereof) equal to $18.92 (the "Initial
Exercise Price").

     2. WARRANT CERTIFICATES.

     The warrant certificates (the "Warrant Certificates") delivered and to be
delivered pursuant to this Agreement shall be in the form set forth as Exhibit
A, attached hereto and made a part hereof, with such appropriate insertions,
omissions, substitutions and other variations as required or permitted by this
Agreement.

     3. EXERCISE OF WARRANTS.

          3.1 CASH EXERCISE.  The Exercise Price may be paid in cash or by check
     to the order of the Company, or any combination of cash or check, subject
     to adjustment as provided in Article 7 hereof. Upon surrender of the
     Warrant Certificate with the annexed Form of Election to Purchase duly
     executed, together with payment of the Exercise Price (as hereinafter
     defined) for the Shares purchased, at the Company's executive offices
     currently located at 5655 Peachtree Parkway Atlanta, Georgia 30092, the
     registered holder of a Warrant Certificate ("Holder" or "Holders") shall be
     entitled to receive a certificate or certificates for the Shares so
     purchased.

                                       O-1
<PAGE>   407

          The purchase rights represented by each Warrant Certificate are
     exercisable at the option of the Holder hereof, in whole or in part (but
     not as to fractional shares of the Common Stock). In the case of the
     purchase of less than all the Shares purchasable under any Warrant
     Certificate, the Company shall cancel said Warrant Certificate upon the
     surrender thereof and shall execute and deliver a new Warrant Certificate
     of like tenor for the balance of the Shares purchasable thereunder.

          3.2 CASHLESS EXERCISE.  At any time during the Warrant Exercise Term,
     the Holder may, at its option, exchange this Warrant, in whole or in part
     (a "Warrant Exchange"), into the number of Shares determined in accordance
     with this Section 3.2, by surrendering this Warrant at the principal office
     of the company or at the office of its transfer agent, accompanied by a
     notice stating such Holder's intent to effect such exchange, the number of
     Shares to be exchanged and the date on which the Holder requests that such
     Warrant Exchange occur (the "Notice of Exchange"). The Warrant Exchange
     shall take place on the date specified in the Notice of Exchange or, if
     later, the date the Notice of Exchange is received by the Company (the
     "Exchange Date"). Certificates for the Shares issuable upon such Warrant
     Exchange and, if applicable, a new warrant of like tenor evidencing the
     balance of the Shares remaining subject to this Warrant, shall be issued as
     of the Exchange Date and delivered to the Holder within seven (7) business
     days following the Exchange Date. In connection with any Warrant Exchange,
     this Warrant shall represent the right to subscribe for and acquire the
     number of Shares (rounded to the next highest integer) equal to (i) the
     number of Shares specified by the Holder in its Notice of Exchange (the
     "Total Number") less (ii) the number of Shares equal to the quotient
     obtained by dividing (A) the product of the Total Number and the then
     existing Exercise Price by (B) the average of the Closing Prices for the
     five Trading Days immediately prior to the date specified in the Notice of
     Exchange.

          3.3 EXERCISE LIMITATION.  In no event shall any Investor be entitled
     to exercise any of the warrants if, upon the exercise of such warrant(s),
     it would cause the aggregate number of shares of Common Stock beneficially
     owned by the Investor and its affiliates to exceed 4.9% of the outstanding
     shares of the Common Stock following such exercise.

     4. ISSUANCE OF CERTIFICATES.

     Upon the exercise of the Warrants, the issuance of certificates for the
Shares shall be made forthwith (and in any event within five business days
thereafter) without charge to the Holder thereof including, without limitation,
any tax which may be payable in respect of the issuance thereof, and such
certificates shall be issued in the name of, or in such names as may be directed
by, the Holder thereof; provided, however, that the Company shall not be
required to pay any tax which may be payable in respect of any transfer involved
in the issuance and delivery of any such certificates in a name other than that
of the Holder and the Company shall not be required to issue or deliver such
certificates unless or until the person or persons requesting the issuance
thereof shall have paid to the Company the amount of such tax or shall have
established to satisfaction of the Company that such tax has been paid.

     The Warrant Certificates and the certificates representing the Shares shall
be executed on behalf of the Company by the manual or facsimile signature of the
present or any future Chairman or Vice Chairman of the Board of Directors, Chief
Executive officer or President or Vice President of the Company under its
corporate seal reproduced

                                       O-2
<PAGE>   408

thereon, attested to by the manual or facsimile signature of the present or any
future Secretary or Assistant Secretary of the Company. Warrant Certificates
shall be dated the date of execution by the Company upon initial issuance,
division, exchange, substitution or transfer.

     The Warrant Certificates and, upon exercise of the Warrants, in part or in
whole, certificates representing the Shares shall bear a legend substantially
similar to the following:

          The securities represented by this certificate have not been
     registered under the Securities Act of 1933, as amended (the "Act"), and
     may not be offered or sold except (i) pursuant to an effective registration
     statement under the Act, (ii) to the extent applicable, pursuant to Rule
     144 under the Act (or any similar rule under such Act relating to the
     disposition of securities), or (iii) upon the delivery by the holder to the
     Company of an opinion of counsel, satisfactory to counsel to the issuer,
     stating that an exemption from registration under such Act is available.

     5. PRICE.

          5.1 ADJUSTED EXERCISE PRICE.  The adjusted Exercise Price shall be the
     price which shall result from time to time from any and all adjustments of
     the Initial Exercise Price in accordance with the provisions of Article 7
     hereof.

          5.2 EXERCISE PRICE.  The term "Exercise Price" herein shall mean the
     Initial Exercise Price or the adjusted Exercise Price, depending upon the
     context.

     6. REGISTRATION RIGHTS.

          6.1 REGISTRATION UNDER THE SECURITIES ACT OF 1993.

          The Warrants and the Shares have not been registered for purposes of
     public distribution under the Securities Act of 1933, as amended ("the
     Act").

          6.2 REGISTRABLE SECURITIES.  As used herein the term "Registrable
     Security" means each of the Warrants, the Shares and any shares of Common
     Stock issued upon any stock split or stock dividend in respect of such
     Shares; provided, however, that with respect to any particular Registrable
     Security, such security shall cease to be a Registrable Security when, as
     of the date of determination, (i) it has been effectively registered under
     the Securities Act and disposed of pursuant thereto, (ii) registration
     under the Securities Act is no longer required for the immediate public
     distribution of such security or (iii) it has ceased to be outstanding. The
     term "Registrable Securities" means any and/or all of the securities
     falling within the foregoing definition of a "Registrable Security." In the
     event of any merger, reorganization, consolidation, recapitalization or
     other change in corporate structure affecting the Common Stock, such
     adjustment shall be made in the definition of "Registrable Security" as is
     appropriate in order to prevent any dilution or enlargement of the rights
     granted pursuant to this Article 6.

          6.3 PIGGYBACK REGISTRATION.  If, at any time during the five years
     following the date of the Initial Closing, the Company proposes to prepare
     and file any registration statement or post-effective amendments (other
     than in connection with an underwritten initial public offering or initial
     registration of the Company or the Company's securities with the U.S.
     Securities & Exchange Commission) thereto covering equity or debt
     securities of the Company, or any such securities of the Company held by
     its

                                       O-3
<PAGE>   409

     shareholders (in any such case, other than in connection with a merger,
     acquisition or pursuant to Form S-8 or successor form), (for purposes of
     this Article 6, collectively, a "Registration Statement"), it will give
     written notice of its intention to do so by registered mail ("Notice"), at
     ten (10) business days prior to the filing of each such Registration
     Statement, to all holders of the Registrable Securities. Upon the written
     request of such a holder (a "Requesting Holder"), made within ten (10)
     business days after receipt of the Notice, that the Company include any of
     the Requesting Holder's Registrable Securities in the proposed Registration
     Statement, the Company shall, as to each such Requesting Holder, use its
     best efforts to effect the registration under the Securities Act of the
     Registrable Securities which it has been so requested to register
     ("Piggyback Registration"), at the Company's sole cost and expense and at
     no cost or expense to the Requesting Holders. Notwithstanding the
     provisions of this Section 6.3, the Company shall have the right at any
     time after it shall have given written notice pursuant to this Section 6.3
     (irrespective of whether any written request for inclusion of such
     securities shall have already been made) to elect not to file any such
     proposed Registration Statement, or to withdraw the same after the filing
     but prior to the effective date thereof.

     7. ADJUSTMENTS OF EXERCISE PRICE AND NUMBER OF SHARES.

          7.1 SUBDIVISION AND COMBINATION.  In case the Company shall at any
     time subdivide or combine the outstanding shares of Common Stock, the
     Exercise Price shall forthwith be proportionately decreased in the case of
     subdivision or increased in the case of combination.

          7.2 ADJUSTMENT IN NUMBER OF SHARES.  Upon each adjustment of the
     Exercise Price pursuant to the provisions of this Article 7, the number of
     Shares issuable upon the exercise of each Warrant shall be adjusted to the
     nearest full Share by multiplying a number equal to the Exercise Price in
     effect immediately prior to such adjustment by the number of Shares
     issuable upon exercise of the Warrants immediately prior to such adjustment
     and dividing the product so obtained by the adjusted Exercise Price.

          7.3 RECLASSIFICATION, CONSOLIDATION, MERGER, ETC.  In case of any
     reclassification or change of the outstanding shares of Common Stock (other
     than a change in par value to no par value, or from no par value to par
     value, or as a result of a subdivision or combination), or in the case of
     any consolidation of the Company with, or merger of the Company into,
     another corporation (other than a consolidation or merger in which the
     Company is the surviving corporation and which does not result in any
     reclassification or change of the outstanding shares of Common Stock,
     except a change as a result of a subdivision or combination of such shares
     or a change in par value, as aforesaid), or in the case of a sale or
     conveyance to another corporation of the property of the Company as an
     entirety, the Holders shall thereafter have the right to purchase the kind
     and number of shares of stock and other securities and property receivable
     upon such reclassification, change, consolidation, merger, sale or
     conveyance as if the Holders were the owners of the shares of Common Stock
     underlying the Warrants immediately prior to any such events at a price
     equal to the product of (x) the number of shares issuable upon exercise of
     the Warrants and (y) the Exercise Price in effect immediately prior to the
     record date for such reclassification, change, consolidation, merger, sale
     or conveyance as if such Holders had exercised the Warrants.

                                       O-4
<PAGE>   410

          7.4 NO ADJUSTMENT OF EXERCISE PRICE IN CERTAIN CASES.  No adjustment
     of the Exercise Price shall be made:

             (a) Upon the issuance or sale of shares of Common Stock upon the
        exercise of the Warrants; or

             (b) Upon (i) the issuance of options pursuant to the Company's
        employee stock option plans in effect or the issuance or sale by the
        Company of any shares of Common Stock pursuant to the exercise of any
        such options, or (ii) the issuance or sale by the Company of any shares
        of Common Stock pursuant to the exercise of any options or warrants; or

             (c) Upon the issuance of shares of Common Stock pursuant to
        contractual obligations; or

             (d) If the amount of said adjustment shall be less than 2 cents
        (2c) per Share, provided, however, that in such case any adjustment that
        would otherwise be required then to be made shall be carried forward and
        shall be made at the time of and together with the next subsequent
        adjustment which, together with any adjustment so carried forward, shall
        amount to at least 2 cents (2c) per Share.

     8. EXCHANGE AND REPLACEMENT OF WARRANT CERTIFICATES.

     Each Warrant Certificate is exchangeable without expense, upon the
surrender hereof by the registered Holder at the principal executive office of
the Company, for a new Warrant Certificate of like tenor and date representing
in the aggregate the right to purchase the same number of Shares in such
denominations as shall be designated by the Holder thereof at the time of such
surrender.

     Upon receipt by the Company of evidence reasonably satisfactory to it of
the loss, theft, destruction or mutilation of any Warrant Certificate, and, in
case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to it, and reimbursement to the Company of all reasonable expenses
incidental thereto, and upon surrender and cancellation of the Warrants, if
mutilated, the Company will make and deliver a new Warrant Certificate of like
tenor, in lieu thereof.

     9. ELIMINATION OF FRACTIONAL INTERESTS.

     The Company shall not be required to issue certificates representing
fractions of shares of Common Stock and shall not be required to issue scrip or
pay cash in lieu of fractional interests, it being the intent of the parties
that all fractional interests shall be eliminated by rounding any fraction up to
the nearest whole number of shares of Common Stock.

     10. RESERVATION AND LISTING OF SECURITIES.

     The Company shall at all times reserve and keep available out of its
authorized shares of Common Stock, solely for the purpose of issuance upon the
exercise of the Warrants, such number of shares of Common Stock as shall be
issuable upon the exercise thereof. The Company covenants and agrees that, upon
exercise of the Warrants and payment of the Exercise Price therefor, all shares
of Common Stock issuable upon such exercise shall be duly and validly issued,
fully paid, non-assessable and not subject to the preemptive rights of any
shareholder. As long as the Warrants shall be outstanding, the Company shall

                                       O-5
<PAGE>   411

use its best efforts, once it has become a public company, to cause all shares
of Common Stock issuable upon the exercise of the Warrants to be listed on or
quoted on the electronic bulletin board, by NASDAQ or listed on such national
securities exchanges.

     11. NOTICES TO WARRANT HOLDERS.

     Nothing contained in this Agreement shall be construed as conferring upon
the Holder or Holders the right to vote or to consent or to receive notice as a
shareholder in respect of any meetings of shareholders for the election of
directors or any other matter, or as having any rights whatsoever as a
shareholder of the Company. If, however, at any time prior to the expiration of
the Warrants and their exercise, any of the following events shall occur:

          (a) the Company shall take a record of the holders of its shares of
     Common Stock for the purpose of entitling them to receive a dividend or
     distribution payable otherwise than in cash, or a cash dividend or
     distribution payable otherwise than out of current or retained earnings, as
     indicated by the accounting treatment of such dividend or distribution on
     the books of the Company; or

          (b) a dissolution, liquidation or winding up of the Company (other
     than in connection with a consolidation or merger) or a sale of all or
     substantially all of its property, assets and business as an entirety shall
     be proposed;

then, in any one or more of said events, the Company shall give written notice
of such event at least fifteen (15) days prior to the date fixed as a record
date or the date of closing the transfer books for the determination of the
shareholders entitled to such dividend, distribution, convertible or
exchangeable securities or subscription rights, options or warrants, or entitled
to vote on such proposed dissolution, liquidation, winding up or sale. Such
notice shall specify such record date or the date of closing the transfer books,
as the case may be. Failure to give such notice or any defect therein shall not
affect the validity of any action taken in connection with the declaration or
payment of any such dividend or distribution, or any proposed dissolution,
liquidation, winding up or sale.

     12. NOTICES.

     All notices, requests, consents and other communications hereunder shall be

          (b) If to the Company, to the address set forth in Section 3 of this
     Agreement or to such other address as the Company may designate by notice
     to the Holders.

     13. SUPPLEMENTS AND AMENDMENTS.

     The Company may from time to time supplement or amend this Agreement
without the approval of any Holders of Warrant Certificates in order to cure any
ambiguity, to correct or supplement any provision contained herein which may be
defective or inconsistent with any provisions herein, or to make any other
provisions in regard to matters or questions arising hereunder which the Company
may deem necessary or desirable and which the Company deems not to adversely
affect the interests of the Holders of Warrant Certificates.

anniversary of the Initial Closing. Notwithstanding the foregoing, this
Agreement will terminate on any earlier date when all Warrants have been

survive such termination until the close of business on fifth anniversary of the
Initial Closing.

             (1) an entity that directly or through one or more intermediaries
        is controlled by the Company, and

        interest, as determined by the Company.

     Section 2 THE STOCK INCENTIVE PLAN.

     2.1 PURPOSE OF THE PLAN.  The Plan is intended to: (a) provide incentive to
officers and key employees of the Company and its Affiliates to stimulate their
efforts toward the continued success of the Company and to operate and manage
the business in a manner

                                       P-2
<PAGE>   420

that will provide for the long-term growth and profitability of the Company; (b)
encourage stock ownership by officers and key employees by providing them with a
means to acquire a proprietary interest in the Company, acquire shares of Stock,
or to receive compensation which is based upon appreciation in the value of
Stock; and (c) provide a means of obtaining, rewarding and retaining key
personnel and consultants.

     2.2 STOCK SUBJECT TO THE PLAN.  Subject to adjustment in accordance with
Section 5.2, 2,000,000 shares of Stock (the "Maximum Plan Shares") are hereby
reserved exclusively for issuance pursuant to Stock Incentives. At no time may
the Company have outstanding under the Plan, Stock Incentives subject to Section
16 of the Exchange Act and shares of Stock issued in respect of Stock Incentives
under the Plan in excess of the Maximum Plan Shares. The shares of Stock
attributable to the nonvested, unpaid, unexercised, unconverted or otherwise
unsettled portion of any Stock Incentive that is forfeited or canceled or
expires or terminates for any reason without becoming vested, paid, exercised,
converted or otherwise settled in full will again be available for purposes of
the Plan.

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

     2.4 ELIGIBILITY AND LIMITS.  Stock Incentives may be granted only to
officers, and key employees and consultants of the Company, or any Affiliate of
the Company; provided, however, that an incentive stock option may only be
granted to an employee of the Company or any Subsidiary. In the case of
incentive stock options, the aggregate Fair Market Value (determined as at the
date an incentive stock option is granted) of stock with respect to which stock
options intended to meet the requirements of Code Section 422 become exercisable
for the first time by an individual during any calendar year under all plans of
the Company and its Subsidiaries may not exceed $100,000; provided further, that
if the limitation is exceeded, the incentive stock option(s) which cause the
limitation to be exceeded will be treated as non-qualified stock option(s).

     Section 3 TERMS OF STOCK INCENTIVES.

     3.1 TERMS AND CONDITIONS OF ALL STOCK INCENTIVES.

     (a) The number of shares of Stock as to which a Stock Incentive may be
granted will be determined by the Committee in its sole discretion, subject to
the provisions of Section 2.2 as to the total number of shares available for
grants under the Plan.

     (b) Each Stock Incentive will either be evidenced by a Stock Incentive
Agreement in such form and containing such terms, conditions and restrictions as
the Committee may determine to be appropriate, or be made subject to the terms
of a Stock Incentive Program, containing such terms, conditions and restrictions
as the Committee may determine to be appropriate. Each Stock Incentive Agreement
or Stock Incentive Program

                                       P-3
<PAGE>   421

is subject to the terms of the Plan and any provisions contained in the Stock
Incentive Agreement or Stock Incentive Program that are inconsistent with the
Plan are null and void.

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

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

     (e) Stock Incentives are not transferable or assignable except by will or
by the laws of descent and distribution or for estate planning purposes (in the
case only of non-qualified options upon prior Board approval) and are
exercisable, during the Participant's lifetime, only by the Participant; or in
the event of the Disability of the Participant, by the legal representative of
the Participant; or in the event of death of the Participant, by the legal
representative of the Participant's estate or if no legal representative has
been appointed, by the successor in interest determined under the Participant's
will.

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

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

     (B) OPTION TERM.  Any incentive stock option is not exercisable after the
expiration of ten (10) years after the date the Option is granted. For an Over
10% Owner, the option is only exercisable for a period of five years from the
date of grant. The term of any non-qualified Stock Option must be as specified
in the applicable Stock Incentive Agreement.

                                       P-4
<PAGE>   422

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

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

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

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

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

     (E) TERMINATION OF INCENTIVE STOCK OPTION.  With respect to an incentive
stock option, in the event of termination of employment of a Participant, the
Option or portion thereof held by the Participant which is unexercised will
expire, terminate, and become unexercisable no sooner than 30 days and no later
than the expiration of three (3) months after the date of termination of
employment; provided, however, that in the case of a holder whose termination of
employment is due to death or Disability, one (1) year will be substituted for
such three (3) month period; provided further, that such time limits may be
exceeded by the Committee under the terms of the grant, in which case, the
incentive stock option will be a nonqualified option if it is exercised after
the time limits that would otherwise apply. For purposes of this Subsection (e),
termination of employment of the Participant will not be deemed to have occurred
if the Participant is employed by another corporation (or a parent or subsidiary
corporation of such other corporation) which has assumed the incentive stock
option of the Participant in a transaction to which Code Section 424(a) is
applicable.

     (F) SPECIAL PROVISIONS FOR CERTAIN SUBSTITUTE OPTIONS.  Notwithstanding
anything to the contrary in this Section 3.2, any Option issued in substitution
for an option previously issued by another entity, which substitution occurs in
connection with a transaction to which Code Section 424(a) is applicable, may
provide for an exercise price computed in

                                       P-5
<PAGE>   423

accordance with such Code Section and the regulations thereunder and may contain
such other terms and conditions as the Committee may prescribe to cause such
substitute Option to contain as nearly as possible the same terms and conditions
(including the applicable vesting and termination provisions) as those contained
in the previously issued option being replaced thereby.

     3.4 [OMITTED]

     3.5 [OMITTED]

     3.6 [OMITTED]

     3.7 [OMITTED]

     3.8 TREATMENT OF AWARDS UPON TERMINATION OF EMPLOYMENT.  Except as
otherwise provided by Plan Section 3.2(e), any award under this Plan to a
Participant who has experienced a Termination of Employment may be canceled,
accelerated, paid or continued, as provided in the applicable Stock Incentive
Agreement or Stock Incentive Program, or, in the absence of such provision, as
the Committee may determine. The portion of any award exercisable in the event
of continuation or the amount of any payment due under a continued award may be
adjusted by the Committee to reflect the Participant's period of service from
the date of grant through the date of the Participant's Termination of
Employment or such other factors as the Committee determines are relevant to its
decision to continue the award.

     Section 4 RESTRICTIONS ON STOCK

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

     4.2 RESTRICTIONS ON TRANSFER.  The Participant does not have the right to
make or permit to exist any disposition of the shares of Stock issued pursuant
to the Plan except as provided in the Plan or the applicable Stock Incentive
Agreement or Stock Incentive Program. Any disposition of the shares of Stock
issued under the Plan by the Participant

                                       P-6
<PAGE>   424

not made in accordance with the Plan or the applicable Stock Incentive Agreement
or Stock Incentive Program will be void. The Company will not recognize, or have
the duty to recognize, any disposition not made in accordance with the Plan and
the applicable Stock Incentive Agreement or Stock Incentive Program, and the
shares so transferred will continue to be bound by the Plan and the applicable
Stock Incentive Agreement or Stock Incentive Program.

     Section 5 GENERAL PROVISIONS

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

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

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

     5.2 CHANGES IN CAPITALIZATION; MERGER; LIQUIDATION.

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

     (b) In the event of a merger, consolidation or other reorganization of the
Company or tender offer for shares of Stock, the Committee may make such
adjustments with respect to awards and take such other action as it deems
necessary or appropriate to reflect such merger, consolidation, reorganization
or tender offer, including, without limitation, the substitution of new awards,
or the adjustment of outstanding awards, the acceleration of awards, the removal
of restrictions on outstanding awards, or the termination of

                                       P-7
<PAGE>   425

outstanding awards in exchange for the cash value determined in good faith by
the Committee of the vested portion of the award. Any adjustment pursuant to
this Section 5.2 may provide, in the Committee's discretion, for the elimination
without payment therefor of any fractional shares that might otherwise become
subject to any Stock Incentive, but except as set forth in this Section may not
otherwise diminish the then value of the Stock Incentive.

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

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

     5.4 COMPLIANCE WITH CODE.  All incentive stock options to be granted
hereunder are intended to comply with Code Section 422, and all provisions of
the Plan and all incentive stock options granted hereunder must be construed in
such manner as to effectuate that intent.

     5.5 RIGHT TO TERMINATE EMPLOYMENT.  Nothing in the Plan or in any Stock
Incentive confers upon any Participant the right to continue as an employee or
officer of the Company or any of its Affiliates or affect the right of the
Company or any of its Affiliates to terminate the Participant's employment at
any time.

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

     5.7 RESTRICTIONS ON DELIVERY AND SALE OF SHARES; LEGENDS.  Each Stock
Incentive is subject to the condition that if at any time the Committee, in its
discretion, shall determine that the listing, registration or qualification of
the shares covered by such Stock Incentive upon any securities exchange or under
any state or federal law is necessary or desirable as a condition of or in
connection with the granting of such Stock Incentive or the purchase or delivery
of shares thereunder, the delivery of any or all shares pursuant to such Stock
Incentive may be withheld unless and until such listing, registration or
qualification shall have been effected. If a registration statement is not in
effect under the Securities Act of 1933 or any applicable state securities laws
with respect to the shares of Stock purchasable or otherwise deliverable under
Stock Incentives then outstanding, the Committee may require, as a condition of
exercise of any Option or as a condition to any other delivery of Stock pursuant
to a Stock Incentive, that the Participant or other recipient of a Stock
Incentive represent, in writing, that the shares received pursuant to the

                                       P-8
<PAGE>   426

Stock Incentive are being acquired for investment and not with a view to
distribution and agree that the shares will not be disposed of except pursuant
to an effective registration statement, unless the Company shall have received
an opinion of counsel that such disposition is exempt from such requirement
under the Securities Act of 1933 and any applicable state securities laws. The
Company may include on certificates representing shares delivered pursuant to a
Stock Incentive such legends referring to the foregoing representations or
restrictions or any other applicable restrictions on resale as the Company, in
its discretion, shall deem appropriate.

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

     5.9 TERMINATION AND AMENDMENT OF THE PLAN.  The Board of Directors at any
time may amend or terminate the Plan without stockholder approval; provided
however, that the Board of Directors may condition any amendment on the approval
of stockholders of the Company if such approval is necessary or advisable with
respect to tax, securities or other applicable laws. No such termination or
amendment without the consent of the holder of a Stock Incentive may adversely
affect the rights of the Participant under such Stock Incentive.

     5.10 STOCKHOLDER APPROVAL.  The Plan must be submitted to the stockholders
of the Company for their approval within twelve months after an amendment to the
Plan which would increase the total number of shares of Stock eligible for
issuance under the Plan. If stockholder approval is not obtained within such
period, such Stock Issuance will be treated as a non qualified option.

     5.11 CHOICE OF LAW.  The laws of the State of Georgia govern the Plan, to
the extent not preempted by federal law, without reference to the principles of
conflict of laws.

     5.12 EFFECTIVE DATE OF PLAN.  The Plan, as amended and restated hereby,
shall become effective December   , 1998, the date of its adoption by the Board
of Directors.

     Section 262 APPRAISAL RIGHTS

     (a) Any stockholder of a corporation of this State who holds shares of
stock on the date of the making of a demand pursuant to subsection (d) of this
section with respect to such shares, who continuously holds such shares through
the effective date of the merger or consolidation, who has otherwise complied
with subsection (d) of this section and who has neither voted in favor of the
merger or consolidation nor consented thereto in writing pursuant to Section 228
of this title shall be entitled to an appraisal by the Court of Chancery of the
fair value of his shares of stock under the circumstances described in
subsections (b) and (c) of this section. As used in this section, the word
"stockholder" means a holder of record of stock in a stock corporation and also
a member of record of a nonstock corporation; the words "stock" and "share" mean
and include what is ordinarily meant by those words and also membership or
membership interest of a member of a nonstock corporation; and the words
"depository receipt" mean a receipt or other instrument issued by a depository
representing an interest in one or more shares, or fractions thereof, solely of
stock of a corporation, which stock is deposited with the depository.

     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to Sections 251, 252, 254, 257, 258, 263 or 264 of this title:

          (1) Provided, however, that no appraisal rights under this section
     shall be available for the shares of any class or series of stock, which
     stock, or depository receipts in respect thereof, at the record date fixed
     to determine the stockholders entitled to receive notice of and to vote at
     the meeting of stockholders to act upon the agreement of merger or
     consolidation, were either (i) listed on a national securities exchange or
     designated as a national market system security on an interdealer quotation
     system by the National Association of Securities Dealers, Inc. or (ii) held
     of record by more than 2,000 holders; and further provided that no
     appraisal rights shall be available for any shares of stock of the
     constituent corporation surviving a merger if the merger did not require
     for its approval the vote of the stockholders of the surviving corporation
     as provided in subsections (f) or (g) of Section 251 of this title.

          (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
     under this section shall be available for the shares of any class or series
     of stock of a constituent corporation if the holders thereof are required
     by the terms of an agreement of merger or consolidation pursuant to
     Sections 251, 252, 254, 257, 258, 263 and 264 of this title to accept for
     such stock anything except:

             a. Shares of stock of the corporation surviving or resulting from
        such merger or consolidation, or depository receipts in respect thereof;

             b. Shares of stock of any other corporation, or depository receipts
        in respect thereof, which shares of stock or depository receipts at the
        effective date of the merger or consolidation will be either listed on a
        national securities exchange or designated as a national market system
        security on an interdealer quotation system by the National Association
        of Securities Dealers, Inc. or held of record by more than 2,000
        holders;

<PAGE>   428

             c. Cash in lieu of fractional shares or fractional depository
        receipts described in the foregoing subparagraphs a. and b. of this
        paragraph; or

             d. Any combination of the shares of stock, depository receipts and
        cash in lieu of fractional shares or fractional depository receipts
        described in the foregoing subparagraphs a., b. and c. of this
        paragraph.

          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under Section 253 of this title is not owned by
     the parent corporation immediately prior to the merger, appraisal rights
     shall be available for the shares of the subsidiary Delaware corporation.

     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

     (d) Appraisal rights shall be perfected as follows:

          (1) If a proposed merger or consolidation for which appraisal rights
     are provided under this section is to be submitted for approval at a
     meeting of stockholders, the corporation, not less than 20 days prior to
     the meeting, shall notify each of its stockholders who was such on the
     record date for such meeting with respect to shares for which appraisal
     rights are available pursuant to subsection (b) or (c) hereof that
     appraisal rights are available for any or all of the shares of the
     constituent corporations, and shall include in such notice a copy of this
     section. Each stockholder electing to demand the appraisal of his shares
     shall deliver to the corporation, before the taking of the vote on the
     merger or consolidation, a written demand for appraisal of his shares. Such
     demand will be sufficient if it reasonably informs the corporation of the
     identity of the stockholder and that the stockholder intends thereby to
     demand the appraisal of his shares. A proxy or vote against the merger or
     consolidation shall not constitute such a demand. A stockholder electing to
     take such action must do so by a separate written demand as herein
     provided. Within 10 days after the effective date of such merger or
     consolidation, the surviving or resulting corporation shall notify each
     stockholder of each constituent corporation who has complied with this
     subsection and has not voted in favor of or consented to the merger or
     consolidation of the date that the merger or consolidation has become
     effective; or

          (2) If the merger or consolidation was approved pursuant to Section
     228 or 253 of this title, the surviving or resulting corporation, either
     before the effective date of the merger or consolidation or within 10 days
     thereafter, shall notify each of the stockholders entitled to appraisal
     rights of the effective date of the merger or consolidation and that
     appraisal rights are available for any or all of the shares of the
     constituent corporation, and shall include in such notice a copy of this
     section. The notice shall be sent by certified or registered mail, return
     receipt requested, addressed to the stockholder at his address as it
     appears on the records of the corporation. Any stockholder entitled to
     appraisal rights may, within 20 days after the date of mailing of the
     notice, demand in writing from the surviving or resulting corporation the
     appraisal of his shares. Such demand will be sufficient if it reasonably
     informs the

                                       Q-2
<PAGE>   429

     corporation of the identity of the stockholder and that the stockholder
     intends thereby to demand the appraisal of his shares.

     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw his demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
his written request for such a statement is received by the surviving or
resulting corporation or within 10 days after expiration of the period for
delivery of demands for appraisal under subsection (d) hereof, whichever is
later.

     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by 1 or more publications at
least 1 week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.

     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to

                                       Q-3
<PAGE>   430

borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted his
certificates of stock to the Register in Chancery, if such is required, may
participate fully in all proceedings until it is finally determined that he is
not entitled to appraisal rights under this section.

     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection (d)
of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation, either within 60
days after the effective date of the merger or consolidation as provided in
subsection (e) of this section or thereafter with the written approval of the
corporation, then the right of such stockholder to an appraisal shall cease.
Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.

     (1) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.

                 PART II: INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Section 14-2-202(b)(4) of the Georgia Business Corporation Code
provides that a corporation's articles of incorporation may contain a provision
eliminating or limiting the personal liability of a director to the corporation
or its shareholders for monetary damages for breach of duty of care or other
duty as a director. This Section also provides, however, that such a provision
shall not eliminate or limit the liability of a director (i) for any
appropriation, in violation of his duties, of any business opportunity of the
corporation, (ii) for acts or omissions involving intentional misconduct or a
knowing violation of law, (iii) for certain other types of liability set forth
in the Code, and (iv) for transactions from which the director derived an
improper personal benefit. Article VI of the Registrant's Articles of
Incorporation contains a provision eliminating or limiting the personal
liability of a director of the Registrant to the fullest extent authorized by
the Georgia Business Corporation Code.

         In addition, Sections 14-2-851 and 14-2-857 of the Georgia Business
Corporation Code, provides for indemnification of directors and officers of the
Registrant for liability and expenses reasonably incurred by them in connection
with any civil, criminal, administrative or investigative action, suit or
proceeding in which they may become involved by reason of being a director or
officer of the Registrant. Indemnification is permitted if the director or
officer acted in a manner which he believed in good faith to be in or not
opposed to the best interests of the Registrant and, with respect to any
criminal action or proceeding, if he had no reasonable cause to believe his
conduct to be unlawful; provided that the Registrant may not indemnify any
director or officer (i) in connection with a proceeding by or in the right of
the corporation in which the director was adjudged liable to the corporation or
(ii) in connection with any other proceeding in which he was adjudged liable on
the basis that personal profit was improperly received by him, except as
determined by a court of competent jurisdiction. Article 9 of the Registrant's
Bylaws contains a provision providing for the indemnification of officers and
directors and advancement of expenses to the fullest extent authorized by the
Georgia Business Corporation Code.

         The Registrant also maintains directors and officers liability
insurance which insures against liabilities that directors and officers of the
Registrant may incur in such capacities.

ITEM 22. UNDERTAKINGS

         The Registrant undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the Registrant's annual
report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Exchange Act) that is incorporated by reference in the
Registration Statement shall be deemed to be a new Registration Statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         The undersigned Registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report, to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article 3 of Regulation S-X is not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim financial information.

         The Registrant undertakes that prior to any public reoffering of the
securities registered hereunder through use of a prospectus which is a part of
this Registration Statement, by any person or party who is deemed to be an
underwriter within the meaning of Rule 145(c), such reoffering prospectus will
contain the information called for by the applicable registration form with
respect to reofferings by persons who may be deemed underwriters, in addition to
the information called for by the other items of the applicable form.

         The Registrant undertakes that every prospectus: (i) that is filed
pursuant to the paragraph immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Securities Act and is used in
connection with an offering of securities subject to Rule 415, will be filed as
a part of an amendment to the Registration Statement and will not be used until
such amendment is effective, and that, for purposes of determining any liability
under the Securities Act, each such post-effective amendment shall be deemed to
be a new Registration Statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.

         The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of such
request, and to send the incorporated documents by first class mail or other
equally prompt means. This includes information contained in documents filed
subsequent to the effective date of the Registration Statement through the date
of responding to the request.

         The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.
