                               PRELIMINARY COPIES
                  MERGER PROPOSED--YOUR VOTE IS VERY IMPORTANT

     We are seeking your approval of the merger of Adatom, Inc. with and into
HealthCore Medical Solutions, Inc. The combined company will be named
Adatom.com, Inc. and will operate Adatom's existing business of an Internet
retailer. Adatom is currently a privately-owned company.

     HealthCore has two classes of common stock outstanding: class A common
stock and class B common stock. In connection with the merger, the sole holder
of class B common stock has agreed to convert his shares into class A common
stock and we will eliminate the authorization of the class B common stock,
change the name of the class A common stock to "Common Stock" and increase the
authorized Common Stock to 50 million shares.

     In the merger, Adatom stockholders will receive approximately 2.17 shares
of HealthCore common stock for each share of Adatom common stock they own, or an
aggregate of 10,689,489 shares, subject to adjustment, and assuming termination
of the escrow agreement described below. Following the merger, Adatom
stockholders will hold approximately 77.5% of the combined company's outstanding
common stock, subject to adjustment.

     The foregoing calculations give effect to the issuance of 2,511,620 shares
of Adatom common stock before the merger and assumes exercise of 396,000 options
and warrants to purchase HealthCore class A common stock at an exercise price of
not greater than $1.25 per share, and exercise of a warrant to purchase 23,315
shares of Adatom common stock.

     Thirteen holders of class A and class B common stock placed an aggregate of
900,000 shares of class A common stock in escrow in connection with HealthCore's
initial public offering in 1997. These holders have agreed, subject to
stockholder approval, to terminate the escrow agreement. The effect of that
termination will be to cancel and return to HealthCore 80% of the holders'
shares held in escrow or an aggregate of 720,000 shares, with the remaining 20%
or an aggregate of 180,000 shares being returned to the holders.

     The merger is subject to various conditions, including the adoption of a
new stock option plan by the stockholders of HealthCore.

     The Boards of Directors of HealthCore and Adatom have determined that the
merger is in the best interests of their stockholders, and each Board
unanimously recommends voting FOR adoption of the merger agreement. In addition,
the HealthCore Board unanimously recommends voting FOR adoption of the new stock
option and the termination of the escrow agreement.

     THE MERGER CANNOT BE COMPLETED UNLESS THE STOCKHOLDERS OF BOTH COMPANIES
APPROVE THE MERGER. You are cordially invited to attend the special meeting of
stockholders to consider and vote on the proposals. Whether or not you plan to
attend the special meeting, it is important that your shares be voted. Please

VOTE. IF YOU FAIL TO VOTE OR TO INSTRUCT YOUR BROKER TO VOTE YOUR SHARES, THE
EFFECT WILL BE THE SAME AS A VOTE AGAINST THE PROPOSALS.

     This summary highlights selected information from this document and may not
contain all the information that is important to you. For a more complete
understanding of the merger and for a more complete description of the legal
terms of the merger, you should read this entire document carefully, as

More Information" (page 70).

THE COMPANIES

HealthCore Medical Solutions Inc.
11904 Blue Ridge Boulevard
Grandview, Missouri 64030
816-736-4900

     Until July 28, 1999, HealthCore developed, marketed and administered a
health care benefit services program designed to enable members to obtain
discounts on purchases of medical products and services through networks of
providers with which HealthCore has executed provider agreements. HealthCore
offered three products: the HealthCare Solutions card, offering discounts for
ancillary medical services; the Medical Solutions Card, providing discounts on
major medical expenses; and the Saving Solutions Card, offering discounts on
ancillary medical and consumer purchases. As a condition to the merger, on
July 28, 1999, we sold this business. While HealthCore's Board of Directors does
not believe stockholder approval of the sale was required, approval of the
merger agreement by HealthCore's stockholders will constitute ratification of
the sale of HealthCore's health care benefits business.

Adatom, Inc.
920 Hillview Court
Suite 160
Milipitas, CA 95035
408-935-7979

     Adatom, Inc. has created an Internet-based retail system, the
www.Adatom.com catalogue superstore site, where goods flow directly from
suppliers to the consumers. This system attempts to reduce costs and expenses by
removing the need for middlemen. In addition to its superstore site, Adatom
provides ancillary services such as website development, administrative support
and e-commerce infrastructure to other retailers who desire to sell their
products on the Internet.

     After the merger, the combined company will operate the business currently
operated by Adatom.

REASONS FOR THE MERGER (PAGES 21 AND 24)

     Our companies are proposing the merger because we believe the combination
of our two companies will provide significant benefits to our stockholders. The
merger will change the focus of HealthCore's business from healthcare benefits
to Internet commerce. We believe significant new growth opportunities are
available on the Internet. The merger will provide Adatom with access to the
capital markets as a publicly-held company and to the cash assets currently held
by HealthCore. The Boards of Directors of both Adatom and HealthCore have voted
unanimously FOR the merger.

CONSIDERATION TO BE RECEIVED BY ADATOM STOCKHOLDERS (PAGE 33)

     Adatom stockholders will receive approximately 2.17 shares of HealthCore
common stock in exchange for each share of Adatom common stock they hold or an
aggregate of 10,689,489 shares, subject to adjustment, and assuming termination
of the escrow agreement. After the merger, Adatom stockholders will own
approximately 77.5% of the common stock of the combined company, subject to
adjustment. The foregoing calculations give effect to the issuance of an
additional 2,511,620 shares of Adatom common stock before the merger and assumes
exercise of 396,000 options and warrants to purchase HealthCore class A common
stock at an exercise price not greater than $1.25 per share, and exercise of a
warrant to purchase 23,315 shares of Adatom common stock. The number of shares
to be received by Adatom stockholders for each share of Adatom common stock they
own will be increased by an additional .018 of a share or an aggregate of
approximately 195,000 shares for every $100,000 by which the HealthCore cash
assets fail to meet the $2.80 million threshold at the time of closing.
HealthCore's cash assets mean all cash and prepaid expenses plus $996,981,
representing the estimates below:

     o $300,000 in expenses paid by HealthCore in connection with the Merger;

                                       1
<PAGE>
     o $296,981 representing the aggregate exercise price of outstanding options
       and warrants to purchase class A common stock at an exercise price of not
       greater than $1.25 per share;

     o $150,000 payable to Neal J. Polan upon termination of his HealthCore
       employment agreement; and

     o $250,000 previously advanced by HealthCore to Adatom.

RECENT MARKET PRICES FOR HEALTHCORE STOCK (PAGE 8)

     April 26, 1999 was the last full trading day prior to our announcement of
the signing of a letter of intent to merge our companies. The closing price for
HealthCore class A common stock on this day was $2.00. September 10, 1999 was
the last practicable trading day prior to the mailing of this joint proxy
statement/prospectus for which stock prices were available. The closing price
for HealthCore class A common stock on that date was $2.47. See page 8 for
information concerning market price data for HealthCore common stock. Similar
information is not available for Adatom since it is a privately held company.

TAX CONSEQUENCES OF THE MERGER
(PAGE 26)

     We expect that the exchange of shares by Adatom stockholders will be
tax-free to Adatom stockholders for federal income tax purposes.

ISSUES THAT YOU ARE ASKED TO VOTE UPON

     HealthCore stockholders:  You are being asked to approve the merger
agreement that includes:

     o the issuance of HealthCore common stock to Adatom stockholders;

     o the amendments to the HealthCore certificate of incorporation, subject to
       adjustment, to change our name, to eliminate the authorized class B
       common stock, to rename the class A common stock to "Common Stock" and to
       increase the authorized common stock from 20 million to 50 million
       shares; and

     (c) the designation of a new board of directors.

You are also being asked to adopt the 1999 Stock Option Plan reserving an
aggregate of 1,400,000 shares of common stock for options granted under that
plan and the termination of the escrow agreement.

     There are 900,000 shares of class A and class B common stock in escrow and
those shares are subject to forfeiture unless certain market price thresholds or
operating performance-based criteria of HealthCore are met by October 2000. None
of these thresholds or criteria has been met to date. HealthCore's management
believed that under its operation of the health care benefits business, it was
unlikely that these thresholds or criteria of the escrow agreement would be met.

     The termination of the escrow agreement will result in the cancellation of
720,000 shares held in escrow. In the absence of this cancellation, Adatom
stockholders would have received an additional 2,480,000 shares of HealthCore
common stock in the merger and the stockholders who had placed their 900,000
shares in escrow would continue to be subject to the risk of forfeiture of those
shares in the event the combined company failed to meet the market price
thresholds and operating performance-based criteria.

     HEALTHCORE'S BOARD OF DIRECTORS HAS UNANIMOUSLY FOUND THESE PROPOSALS TO BE
ADVISABLE AND RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE PROPOSALS DETAILED IN
THIS PROXY STATEMENT.

     Adatom stockholders:  You are being asked to approve the merger and the
merger agreement. ADATOM'S BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE
MERGER AND THE MERGER AGREEMENT AND RECOMMENDS VOTING FOR APPROVAL OF THE MERGER
AND THE MERGER AGREEMENT.

OPINION OF FINANCIAL ADVISOR TO HEALTHCORE
(PAGE 22)

     HealthCore.  The HealthCore Board of Directors has obtained an opinion
dated August 30, 1999, from its independent financial advisor, Kaufman Bros.,
L.P. to the effect that, at that date and based upon and subject to certain
matters stated therein, the exchange ratio of approximately 2.17 shares of
HealthCore common stock for each share of Adatom common stock, subject to
adjustment, is fair to the HealthCore stockholders from a financial point of
view. A copy of the written opinion from Kaufman Bros., L.P. is attached to this
joint proxy

                                       2
<PAGE>
statement/ prospectus as Annex B. HealthCore has paid Kaufman Bros., L.P. a fee
of $65,000 for this opinion.

RECORD DATE; VOTING POWER (PAGE 29)

     You are entitled to vote at the stockholders' meeting if you owned shares
entitled to vote as of the close of business on September 10, 1999, the record
date for the meetings.

     On the record date, there were 3,183,000 shares of class A common stock
entitled to vote at the HealthCore special meeting and 216,000 shares of
HealthCore class B common stock entitled to vote at the HealthCore special
meeting. HealthCore stockholders owning class A common stock will be entitled to
one vote at the special meeting for each share held of record on the record
date. HealthCore stockholders owning class B common stock will be entitled to
five votes at the special meeting for each share held of record on the record
date.

     On the record date, there were 2,384,600 shares of Adatom common stock
entitled to vote at the Adatom special meeting. Adatom stockholders will be
entitled to one vote at the special meeting for each share of Adatom common
stock held of record on the record date.

VOTES REQUIRED (PAGE 30)

     Approval by HealthCore stockholders of the merger agreement requires the
affirmative vote of more than 50% of the votes of class A common stock and
class B common stock outstanding on the record date voting as a single class or
2,131,501 votes of a total of 4,263,000 votes of the combined classes. That
approval will include the issuance of HealthCore common stock, the amendments to
HealthCore's certificate of incorporation and the designation of a new board of
directors.

     In addition, unless waived by Adatom, the merger must be approved by more
than 50% of the shares of class A common stock outstanding on the record date
excluding the 165,000 shares of class A common stock beneficially owned by
Mr. Polan other than proxies he has obtained from non-family members, or
1,509,001 shares of a total of 3,018,000 shares of class A common stock.

     While HealthCore's Board of Directors does not believe that stockholder
approval was required for the sale of its healthcare benefits business, approval
of the merger agreement by HealthCore's stockholders will constitute
ratification of the sale.

     The approval of the 1999 Stock Option Plan will require the affirmative
vote of more than 50% of the votes of class A and class B common stock voting as
a single class, represented in person or by proxy at the special meeting.

     Approval of the termination of the escrow agreement will require the
approval of at least two-thirds of the shares of class A common stock
outstanding on the record date excluding all shares of class A common stock held
by escrow stockholders whether or not those shares are subject to the escrow
agreement.

     In the event the stockholders of HealthCore fail to approve the termination
of the escrow agreement, Adatom stockholders have agreed to vote all of their
shares of the combined company to approve the termination of the escrow
agreement at the first annual or special meeting of the stockholders of the
combined company following the merger.

     Approval by Adatom stockholders of the merger and the merger agreement will
require the approval of more than 50% of the shares of Adatom common stock
outstanding on the record date, or 1,192,301 shares of the 2,384,600 shares
outstanding. All Adatom stockholders have agreed to vote for the merger.

WHAT YOU NEED TO DO NOW (PAGE 31)

     Just indicate on your proxy card how you want to vote, sign it and mail it
in the enclosed return envelope as soon as possible, so that your shares will be
represented at your stockholders' meeting.

     If you sign and send in your proxy and do not indicate how you want to
vote, your proxy will be counted as a vote in favor of the proposals. If you do
not vote or you abstain, it will have the effect of a vote against the
proposals.

     The HealthCore special meeting and the Adatom special meeting will take
place on Monday, October 11, 1999, at 9:00 a.m. (local time). You may attend
your stockholders' meeting and vote your shares in person, rather than signing
and mailing your proxy card. In addition, you may withdraw your proxy up to and
including the day of your stockholders' meeting by following the directions on
page 31 and either change your vote or attend your stockholders' meeting and
vote in person.

                                       3
<PAGE>
     Your broker will vote your HealthCore and Adatom shares only if you provide
instructions on how to vote. WITHOUT INSTRUCTIONS, YOUR SHARES WILL NOT BE
VOTED. WE WILL COUNT SHARES THAT YOU DO NOT VOTE AS VOTES AGAINST THE PROPOSALS.

   YOUR VOTE IS VERY IMPORTANT.

STOCK CERTIFICATES

     If you are an Adatom common stockholder, after the merger is completed we
will send you written instructions for exchanging your Adatom common stock
certificates. If you are a HealthCore stockholder, you should retain your stock
certificates as the merger will not require surrender of HealthCore stock
certificates at any time. See page 31 for further details.

SHARE OWNERSHIP OF MANAGEMENT AND CERTAIN STOCKHOLDERS (PAGES 61 AND 69)

     On the record date, directors and executive officers of HealthCore and
their affiliates may be deemed to be the beneficial owners of 187,000 shares of
HealthCore class A common stock or approximately 5.9% of the HealthCore class A
common stock outstanding. Excluding Mr. Polan's 165,000 shares of class A common
stock, these other directors and executive officers and their affiliates own
approximately 22,000 shares of class A common stock representing less than 1% of
the 3,018,000 shares of class A common stock so outstanding.

     On the record date, Neal Polan, Chairman and Chief Executive Officer of
HealthCore may be deemed to be the beneficial owner of all of the 216,000 shares
of HealthCore class B common stock, outstanding. Accordingly, on the record
date, directors and executive officers of HealthCore and their affiliates held
approximately 29.7% of the voting power of the combined class A and class B
common stock. This voting power percentage does not take into account the shares
of class A common stock that Mr. Polan has the right to vote under proxies given
to him by the escrow stockholders, as described below.

     Neal Polan has agreed to vote all his 165,000 shares of class A common
stock and 216,000 shares of class B common stock in favor of the merger and
related transactions.

     In addition, all the other directors and executive officers of HealthCore
have indicated that they intend to vote the class A common stock owned by them
for all the HealthCore proposals detailed in this proxy statement.

     All escrow stockholders have given Neal Polan a proxy to vote all shares of
class A common stock they own, including all shares held in escrow, in favor of
all proposals that come before the special meeting. After giving effect to these
proxies, the executive officers and directors of HealthCore and their affiliates
have the right to vote at least 47% of the voting power of the combined class A
and class B common stock.

     On the record date, there were four holders of Adatom common stock
outstanding. These holders, all of whom are directors of Adatom, have agreed to
vote the Adatom common stock owned by them for the approval of the merger and
the merger agreement.

INTERESTS OF CERTAIN PERSONS IN THE MERGER (PAGE 27)

     A number of directors, executive officers and stockholders of HealthCore
and Adatom have interests in the merger that are different from, or in addition
to, yours as a stockholder.

     These interests include the following:

     o HealthCore stockholders who have placed shares in escrow will, subject to
       stockholder approval of the termination of the escrow agreement,
       surrender and forfeit 80% of their shares or an aggregate of 720,000
       shares and receive at the time of the merger or after if the termination
       occurs subsequent to the merger 20% of their shares or an aggregate of
       180,000 shares, free of the risk of forfeiture and other transfer
       restrictions imposed by the escrow. agreement.

     o Richard Barton, the President and CEO of Adatom, will enter into a
       three-year employment agreement with the combined company at an annual
       base salary of $200,000 plus a $100,000 bonus based upon the attainment
       of performance goals.

     o David Mullikin, HealthCore's President, will obtain the following
       benefits:

       o At the closing of the merger, HealthCore will terminate the employment
         of David Mullikin. He will receive a severance

                                       4
<PAGE>
         package from HealthCore which provides for a payment of $100,000 plus
         100,000 options to purchase shares of HealthCore at $.10 per share.
         Mr. Mullikin will also receive registration rights for the shares of
         stock underlying those options. This severance is in lieu of the
         severance to which he was previously entitled under his existing
         employment agreement, namely $150,000 reduced by 50% of any
         compensation he receives from other employment during the one year
         period following termination, but in no event less than $75,000.

     o Neal J. Polan, HealthCore's Chairman of the Board and Chief Executive
       Officer, will obtain the following benefits:

       o At the closing of the merger, Mr. Polan will enter into a two-year
         employment agreement with the Adatom which provides for an annual
         salary of $50,000. Mr. Polan will be required to work up to 60 hours
         per month as an advisor for the surviving company in mergers,
         acquisitions and strategic alliances. Mr. Polan will receive a right to
         purchase stock in Adatom in an amount equal to that number of Adatom
         shares convertible into 350,000 shares of HealthCore common stock in
         the merger in exchange for a promissory note in the amount of $320,760.
         As partial consideration for his services rendered under the employment
         agreement, the promissory note will be forgiven six months after the
         closing date of the merger.

       o On April 27, 1999, Mr. Polan agreed to amend his existing employment
         agreement with HealthCore to permit HealthCore to terminate his
         employment without cause and to revise the terms of his severance
         package. Mr. Polan's original employment agreement provided that in the
         event that Mr. Polan's employment is terminated without cause,
         HealthCore would be required to pay him all sums that would have been
         paid under the agreement. The amended employment agreement reduces the
         amount of severance upon termination of employment and provides that
         HealthCore would only have to pay Mr. Polan the lesser of $150,000 or
         60% of the remaining value of the contract at the time of termination.
         In consideration for agreeing to the amended employment agreement,
         Mr. Polan received 165,000 shares of HealthCore class A common stock.

       o Mr. Polan owns shares that are subject to the escrow agreement, and
         will be treated identical to those held by the other escrow
         stockholders described above.

       o Mr. Polan will receive registration rights covering 367,800 shares,
         including 142,000 shares underlying warrants.

       o In September 1997, in connection with his employment with HealthCore,
         Mr. Polan received a warrant to purchase 142,000 shares of HealthCore
         class A common stock at $1.00 per share. The warrant becomes
         exercisable if certain market price thresholds or operating
         performance-based criteria of HealthCore are met. In connection with
         the merger, Mr. Polan has agreed to exchange that warrant for 28,400
         shares of HealthCore class A common stock at the closing of the merger.

       o Mr. Polan will also be designated a member of the initial Board of
         Directors of the combined company.

     On July 8, 1999 Eli Levitin, a director of HealthCore, purchased $50,000 of
convertible debt of Adatom through Jesup & Lamont Acquisition Corporation, a
company in which Mr. Levitin has a 10% interest. These securities will be
converted into shares of Adatom common stock immediately prior to the merger and
will then be exchanged for 50,661 shares of common stock of Adatom.com, Inc.
pursuant to the merger.

     The Boards of Directors of HealthCore and Adatom recognized these interests
and determined that they did not affect the benefits of the merger to the
stockholders. Please refer to pages 26 through 28 for more information
concerning these interests.

DIRECTORS AND EXECUTIVE OFFICERS OF ADATOM FOLLOWING THE MERGER (PAGE 71)

     If we complete the merger, the Board of Directors of the combined company
will initially consist of the following five members:

     o Richard Barton, the Chairman of the Board and Chief Executive Officer of
       Adatom and Sridhar Jagannathan, both of whom are currently members of the
       Adatom Board of Directors; and

     o Ralph Kennedy Frasier and Sylvia A. Dresner who have been appointed as
       outside directors have been designated by Adatom;

     o Neal J. Polan, HealthCore's Chairman and Chief Executive Officer.

     Your vote to approve the merger agreement will include the designation of
the foregoing members to the Board of Directors of the combined company.

     The officers of Adatom at the effective time of the merger will be the
officers of the combined company.

LISTING AND TRADING OF HEALTHCORE COMMON STOCK (PAGE 76)

     HealthCore class A common stock is currently listed on the Nasdaq Small Cap
Market. The surviving company will be deemed to be a new company for listing
purposes and will be required to meet the initial listing qualification criteria
of the Nasdaq Small Cap Market.

     These initial listing criteria generally include a minimum of:

     o $4 million in net tangible assets, or

     o $50 million in market capitalization.

     If the surviving company does not meet the relevant criteria which we
expect it will not, immediately following the merger, its common stock risks
being delisted. If this occurs, trading in the common stock would be conducted
in the over-the-counter market in the so-called "pink sheets" or, if available,
the "OTC Bulletin Board Service." As a result, an investor would likely find it
significantly more difficult to dispose of, or to obtain accurate quotations as
to the value of, HealthCore's securities.

RESALE OF HEALTHCORE COMMON STOCK RECEIVED IN THE MERGER (PAGE 28)

     All of the shares of HealthCore common stock issued in the merger to Adatom
directors and executive officers and owned by Mr. Polan will be subject to
resale restrictions under the federal securities laws. This totals 9,722,373
shares of the 13,346,228 shares of the combined company's common stock
outstanding after the merger, or 73% of the shares of the surviving company's
common stock outstanding after the merger.

     In addition, all former holders of Adatom securities, Neal Polan, and David
Mullikin, have entered into lock-up agreements that prohibit transfer of some or
all of their respective shares of Adatom.com, Inc.'s common stock for up to a
period of six months. This totals an aggregate of 11,628,289 shares, including
317,661 shares issuable upon exercise of options or warrants.

     Please refer to page 28 for more information concerning restrictions on
resales.

OTHER CONDITIONS (PAGE 35)

     The obligation of each of us to consummate the merger is subject to the
satisfaction or waiver of various typical conditions, including the absence at
any time after the date of the merger agreement of any material adverse change
relating to the other party.

     Among other things, Adatom is not obligated to consummate the merger if
HealthCore's closing cash amount, as calculated in the manner described earlier,
is less than $2 million.

CANCELLATION OF THE MERGER (PAGE 37)

     We can jointly agree to call off the merger at any time before completing
the merger. Either of us can call off the merger if:

     o the other party has not complied with or has breached in any material
       respect any of its covenants, agreements, warranties or representations
       contained in the merger agreement, which has not been cured within 10
       business days following notice of such breach;

     o if the merger is not consummated before November 30, 1999, provided,
       however that the terminating party can not have caused the failure to
       consummate the merger due to a material breach;

                                       6
<PAGE>
     o the stockholders of either party do not approve the merger;

     o if the Board of Directors of HealthCore recommends an alternative
       transaction to its stockholders, within limits detailed in the merger
       agreement; or

     o there is a legal prohibition preventing the consummation of the merger

FORWARD-LOOKING STATEMENTS MAY PROVE INACCURATE (PAGE 12)

     We have made forward-looking statements in this document that are subject
to risks and uncertainties. Forward-looking statements include information
concerning possible or assumed future results of operations of our company.
Also, when we use words such as "believes," "expects," "anticipates," or similar
expressions, we are making forward-looking statements. You should note that many
factors, some of which are discussed elsewhere in this document, could affect
the future financial results of the combined company and could cause those
results to differ materially from those expressed in our forward-looking
statements contained in this joint proxy statement. These factors include but
are not limited to:

     o trends affecting our financial condition or results of operations;

     o our business and growth strategies;

     o the Internet; and

     o our financing plans.

COMPARATIVE RIGHTS OF STOCKHOLDERS OF HEALTHCORE AND ADATOM (PAGE 81)

     HealthCore is incorporated under the laws of the State of Delaware and
Adatom is incorporated under the laws of the State of California. Adatom
stockholders will, upon consummation of the merger, become stockholders of
HealthCore and their rights will be governed by Delaware law, the certificate of
incorporation of HealthCore and the by-laws of HealthCore. The Delaware
corporate law differs in some respects from California corporate law. For
example, the stockholders of the surviving company will not have the right to
cumulative voting that Adatom stockholders had. Please refer to pages 82 through
89 for more information concerning these differences.

STOCKHOLDERS WILL NOT HAVE
DISSENTERS' RIGHTS

     Under California law, Adatom stockholders who do not vote in favor of the
merger would normally have the right to demand that Adatom purchase their shares
at fair market value. The Adatom stockholders, however, have agreed to vote
their shares in favor of the merger. Therefore, Adatom stockholders will not
have dissenters' rights.

     Under Delaware law, HealthCore stockholders are not entitled to dissenters'
rights because the stock is designated as a national market system security on
an interdealer quotation system by the NASD.

                                  RISK FACTORS

     Before determining whether to approve the merger, you should be aware that
there are various risks, including those described below. You should consider
carefully these risk factors together with all of the other information included
in this joint proxy statement/prospectus.

     We have each made forward-looking statements in this document that are
subject to risks and uncertainties. These statements are based on the beliefs
and assumptions of the respective company's management, and on information
currently available to such management. Forward-looking statements include the
information concerning possible or assumed future results of our operations set
forth under "Summary," "The Merger--Background of the Merger," "--HealthCore's
Reasons for the Merger; Recommendation of its Board of Directors," "--Opinion of
HealthCore Board of Directors' Financial Advisor," "--Adatom's Reasons for the
Merger; Recommendation of its Board of Directors," and "HealthCore and Adatom
Unaudited Pro Forma Condensed Combined Financial Statements," and statements
preceded by, followed by or that include the words "believes," "expects,"
"anticipates," "intends," "plans," "estimates" or similar expressions.

     Forward-looking statements are not guarantees of performance. They involve
risks, uncertainties and assumptions. The future results and stockholder values
of the combined company following the merger may differ materially from those
expressed in these forward-looking statements. Many of the factors that will
determine these results and values are beyond our ability to control or predict.
Stockholders are cautioned not to put undue reliance on any forward-looking
statements. In addition, we do not have any intention or obligation to update
forward-looking statements after we distribute this joint proxy
statement/prospectus, even if new information, future events or other
circumstances have made them incorrect or misleading. For those statements, we
are relying on the protection of the safe harbor for forward-looking statements
contained in the Private Securities Litigation Reform Act of 1995.

     You should understand that the following important factors could affect the
future results of the combined company following the merger, and could cause
results to differ materially from those expressed in such forward-looking
statements.

     RISKS THAT AFFECT THE COMBINED COMPANY. THESE RISKS RELATE TO ADATOM'S
BUSINESS AS WE WILL BE OPERATING THAT BUSINESS AFTER THE MERGER.

WE HAVE A HISTORY OF LOSSES AND EXPECT FUTURE LOSSES.

     Since inception in 1996, Adatom has incurred significant losses, and as of
June 30, 1999, had an approximate accumulated deficit of $2,821,000 and there is
an uncertainty about our ability to continue as a going concern. We are a
development stage company and expect to incur substantial operating losses for
the foreseeable future as we incur significant operating expenses and research
and development expenses and make investments, to enhance our line of products
and services and establish internet capabilities. We intend to substantially
increase our marketing and promotional spending to increase our revenues. We may
never generate sufficient revenues to achieve profitability. Even if we do
achieve profitability, we may not be able to sustain or increase profitability
on a quarterly or annual basis in the future.

WE NEED ADDITIONAL FINANCING TO FUND OUR BUSINESS AND THE FAILURE TO OBTAIN
FINANCING COULD RESULT IN CESSATION OF OUR BUSINESS.

     We need additional funds to sustain and expand our sales and marketing
activities and our marketing arrangements, particularly if a well-financed
competitor emerges or if there is a shift in the type of Internet services that
are developed and ultimately receive customer acceptance. Adequate funds for
these and other purposes on terms acceptable to us, whether through additional
equity financing, debt financing or other sources, may not be available when
needed or may result in significant dilution to existing stockholders. Failure
to obtain financing could result in cessation of our business.

     HealthCore has retained Jesup & Lamont Securities Corporation to raise
$5.5 million through the private placement of the combined company's equity
securities in order to satisfy its short term financing needs. The equity
securities have not yet been sold, and we cannot be sure that any of the equity
securities will be sold,

                                       12
<PAGE>
or if sold on terms favorable to us, or that the funds received, if any, will be
sufficient to fund operations until we are profitable, if at all.

     Our lack of tangible assets to pledge could prevent us from obtaining bank
or similar debt financing. In addition, we cannot be sure that such financing
will be available in amounts or on terms acceptable to us, if at all. The
inability to obtain sufficient funds from operations and external sources would
have a material adverse effect on us and could result in cessation of our
business.

     In its report on its audit of Adatom's financial statements for the year
ended December 31, 1998, its independent accountants included an explanatory
paragraph in their report because of the uncertainty that Adatom could continue
in business as a going concern. Unless it raises additional capital, the
combined company expects it will exhaust its working capital in approximately
four months after the merger. Any raise of additional capital will dilute all
stockholders of the combined company.

WE DEPEND HEAVILY UPON MARKETING ARRANGEMENTS. WITHOUT THEM, OUR BUSINESS WILL
BE ADVERSELY AFFECTED.

     We rely on certain marketing arrangements with other companies that have
websites to attract shoppers to purchase our products. Adatom has entered into
marketing arrangements with a number of existing organizations with a definable
user base. Our ability to generate revenues from online commerce depends, among
other things, upon the increased traffic, purchases, advertising and
sponsorships that we generate through our marketing arrangements. We cannot be
sure that other companies will continue these relationships with us, or, if
continued, that they will be on terms favorable to us. Our inability to enter
into new marketing arrangements or to maintain our existing arrangements would
have a material adverse effect on us.

WE RELY ON SUPPLIERS FOR OUR RETAIL MERCHANDISE AND SHIPMENTS TO CUSTOMERS. LOSS
OF THESE RELATIONSHIPS COULD HAVE A MATERIAL ADVERSE EFFECT ON OUR BUSINESS.

     Our current suppliers may not continue to sell merchandise to us on current
terms. We may not be able to maintain our current arrangements with suppliers or
be able to establish new or extend current supplier relationships to ensure
acquisition of merchandise in a timely and efficient manner and on acceptable
commercial terms. Loss of these relationships could have a material adverse
effect on us. We also rely on most of our suppliers to process and ship
merchandise directly to customers. We have limited control over the shipping
procedures of our suppliers, and shipments by these suppliers have at times been
subject to delays. If the quality of service provided by such suppliers falls
below a satisfactory standard or if our level of returns exceeds our
expectations, our business will be materially adversely affected.

WE MAY NOT BE ABLE TO EFFECTIVELY MANAGE THE GROWTH OF OUR BUSINESS.

     To manage the expected growth of our operations and personnel, we will be
required to improve existing and implement new transaction-processing,
operational and financial systems, procedures and controls, and to expand, train
and manage our already growing employee base. Further, we will be required to
maintain and expand our relationships with various merchandise manufacturers,
distributors, Internet and other online service providers and other third
parties necessary to our business. If we are unable to manage growth
effectively, our business will be materially adversely affected.

THE LOSS OF KEY PERSONNEL COULD HAVE A MATERIAL ADVERSE EFFECT ON US.

     Our performance will be substantially dependent on the continued services
and on the performance of our senior management, particularly Richard Barton,
Adatom's President, Chief Executive Officer and Chairman of the Board, and
Sridhar Jagannathan, Chief Technical Officer and Executive Vice President. Our
performance also depends on our ability to retain and motivate our other
officers and key employees. The loss of the services of any of our executive
officers or other key employees could have a material adverse effect on us. Our
future success also depends on our ability to identify, attract, hire, train,
retain and motivate other highly skilled technical, managerial, editorial,
merchandising, marketing and customer service personnel.

                                       13
<PAGE>
Competition for such personnel is intense, and we may not be able to
successfully attract, assimilate or retain sufficiently qualified personnel.
This inability could have a material adverse effect on us.

POTENTIAL FLUCTUATIONS IN OUR QUARTERLY RESULTS MAY CAUSE VOLATILITY IN OUR
STOCK VALUATION.

     We expect to experience significant fluctuations in our future quarterly
operating results due to a variety of factors, many of which are outside of our
control. Factors that may adversely affect our quarterly operating results
include, without limitation:

     o Our ability to retain existing customers, attract new customers at a
       steady rate and maintain customer satisfaction,

     o the announcement or introduction of new sites, services and products by
       us and our competitors,

     o price competition in the industry,

     o the level of use of the Internet and online services and increasing
       consumer acceptance of the Internet and other online services for the
       purchase of consumer products such as those offered by us,

     o Our ability to upgrade and develop our systems and infrastructure and
       attract new personnel in a timely and effective manner,

     o the level of traffic on our web site,

     o technical difficulties, system downtime or Internet brownouts,

     o the amount and timing of operating costs and capital expenditures
       relating to expansion of our business, operations and infrastructure,

     o the implementation of strategic alliances,

     o the level of merchandise returns experienced by us, and

     o governmental regulation

     We expect that we will experience seasonality in our business, reflecting a
combination of seasonal fluctuations in Internet usage and traditional retail
seasonality patterns. Internet usage and the rate of Internet growth may be
expected to decline during the summer. Further, sales in the traditional retail
industry are significantly higher in the fourth calendar quarter of each year
than in the preceding three quarters. Due to the foregoing factors, in one or
more future quarters our operating results may fall below the expectations of
securities analysts and investors. In such event, the trading price of the
common stock would likely be materially adversely affected.

WE MAY BE UNABLE TO PROTECT OUR TRADEMARKS AND PROPRIETARY RIGHTS WHICH WOULD
HAVE A MATERIAL ADVERSE EFFECT ON OUR BUSINESS.

     Our performance and ability to compete are dependent to a significant
degree on our proprietary technology. We regard our copyrighted material,
service marks, trademarks, trade secrets and similar intellectual property as
critical to our success, and rely on trademark and copyright law, trade secret
protection and confidentiality and/or license agreements with our employees,
customers, partners and others to protect our proprietary rights. We have the
registered trademarks "Adatom" and "Discovering New Shopping Dimensions" in the
United States and have a trademark application pending for the mark "Adatom Home
Dimensions." We cannot be sure that we will be able to secure significant
protection for these trademarks. It is possible that competitors of Adatom or
others will adopt product or service names similar to "Adatom" and our other
trademarks, thereby impeding our ability to build brand identity and possibly
leading to customer confusion.

     We generally have entered into agreements containing confidentiality and
non-disclosure provisions with our employees and consultants and limits access
to and distribution of its software, documentation and other proprietary
information. We cannot be sure that the steps taken by us will prevent
misappropriation of our technology or that agreements entered into for that
purpose will be enforceable. Notwithstanding the

                                       14
<PAGE>
precautions taken by us, it might be possible for a third party to copy or
otherwise obtain and use our software or other proprietary information without
authorization or to develop similar software independently. Policing
unauthorized use of our technology is difficult, particularly because the global
nature of the Internet makes it difficult to control the ultimate destination or
security of software or other data transmitted. The laws of other countries may
afford us little or no effective protection of our intellectual property.
Effective trademark, service mark, copyright and trade secret protection may not
be available in every country in which our products and services are made
available online. In the future, we may also need to file lawsuits to enforce
our intellectual property rights, protect its trade secrets, and determine the
validity and scope of the proprietary rights of others. Such litigation, whether
successful or unsuccessful, could result in substantial costs and diversion of
resources, which could have a material adverse effect on us.

     We also rely on a variety of technology that we license from third parties,
including our database and Internet server software, which is used in our web
site to perform key functions. These third party technology licenses may not
continue to be available to us on commercially reasonable terms. Our loss of or
inability to maintain or obtain upgrades to any of these technology licenses
could result in delays in completing our proprietary software enhancements and
new developments until equivalent technology could be identified, licensed or
developed and integrated. Any such delays would have a material adverse effect
on us.

WE MAY EXPERIENCE CAPACITY CONSTRAINTS DUE TO OUR RELIANCE ON INTERNALLY
DEVELOPED TRANSACTION-PROCESSING SYSTEMS.

     If we suffer any system interruptions that result in the unavailability of
our store on the Internet or reduced order fulfillment capability, such
interruptions would reduce the volume of goods sold and the attractiveness of
our product offerings. We have experienced periodic system interruptions, which
we believe will continue to occur from time to time. The satisfactory
performance, reliability and availability of our store on the Internet,
transaction-processing systems and network infrastructure are critical to our
reputation and our ability to attract and retain customers and maintain adequate
customer service levels. Our revenues depend on the number of visitors who shop
at its store on the Internet and the volume of orders it fulfills.

     There will be a significant need to upgrade the capacity of our store on
the Internet in order to handle thousands of simultaneous shoppers. Our
inability to add additional software and hardware or to develop and upgrade
further our existing technology, transaction-processing systems or network
infrastructure to accommodate increased traffic on our store on the Internet or
increased sales volume through our transaction-processing systems may cause
unanticipated system disruptions, slower response times, degradation in levels
of customer service and impaired quality and speed of order fulfillment, any of
which could have a material adverse effect on us.

OUR BUSINESS MAY SUFFER IF OUR SYSTEMS FAIL OR IF THE SYSTEMS OF OUR BUSINESS
PARTNERS FAIL.

     We presently have limited redundant systems. We do not have a complete
disaster recovery plan and carry limited business interruption insurance to
compensate us for losses that may occur. Despite our implementation of network
security measures, our servers are vulnerable to computer viruses, physical or
electronic break-ins and similar disruptions, which could lead to interruptions,
delays, loss of data or the inability to accept and fulfill customer orders. Our
ability to successfully receive and fulfill orders and provide high-quality
customer service, largely depends on the efficient and uninterrupted operation
of its computer and communications hardware systems. Our systems and operations
are vulnerable to damage or interruption from fire, flood, power loss,
telecommunications failure, break-ins, earthquake and similar events. In
addition, any disruptions of those web sites or at the web sites of other
companies where we market goods or have a website link could have a material
adverse effect on us and the volume of sales generated. The occurrence of any of
the foregoing risks could have a material adverse effect on us.

IF WE ARE NOT ABLE TO SUSTAIN RAPID TECHNOLOGICAL CHANGES, OUR BUSINESS MAY
SUFFER.

     We may not successfully use new technologies effectively or adapt our store
on the Internet, proprietary technology and transaction-processing systems to
customer requirements or emerging industry standards. Our failure to adapt in a
timely manner for technical, legal, financial or other reasons, to changing
market

                                       15
<PAGE>
conditions or customer requirements, could have a material adverse effect on us.
To remain competitive, we must continue to enhance and improve the
responsiveness, functionality and features of our online stores. The Internet
and the online commerce industry are characterized by rapid technological
change, changes in user and customer requirements and preferences, frequent new
product and service introductions embodying new technologies and the emergence
of new industry standards and practices that could render our existing store on
the Internet and proprietary technology and systems obsolete. Our success will
depend, in part, on our ability to license leading technologies useful in its
business, enhance our existing services, develop new services and technology
that address the increasingly sophisticated and varied needs of our prospective
customers, and respond to technological advances and emerging industry standards
and practices on a cost-effective and timely basis.

WE MAY ENCOUNTER MATERIAL COSTS RELATING TO YEAR 2000 COMPLIANCE.

     Although we have tested our currently installed computer systems and
software products for year 2000 problems and we believe that our computer
systems and software products are fully year 2000 compatible, it is possible
that certain computer systems or software products of our suppliers or customers
may not accept input of, store, manipulate and output dates prior to the year
2000 or thereafter without error or interruption. We have conducted a review of
our computer systems, to attempt to identify ways in which our systems could be
affected by problems of our customers and suppliers in correctly processing date
information. In addition, we are requesting assurances from all software vendors
from which we have purchased or from which we may purchase software that such
software will correctly process all date information at all times. Furthermore,
we are querying our customers and suppliers as to their progress in identifying
and addressing problems that their computer systems will face in correctly
processing date information as the year 2000 approaches. However, we may not be
able to identify all date-handling problems of our customers and suppliers in
advance of their occurrence,. We may be unable to successfully remedy problems
that are discovered. The expenses of our efforts to identify and address such
problems could be high and we could become subject to liabilities as a result of
such problems. Any of the foregoing issues could have a material adverse effect
on us.

     WE ARE AFFECTED BY THE FOLLOWING INDUSTRY RISKS.

ONLINE COMMERCE IS A VERY COMPETITIVE INDUSTRY. WE EXPECT THE COMPETITION TO
INTENSIFY IN THE FUTURE AND WE RISK FAILURE DUE TO THAT COMPETITION.

     Many of our current and potential competitors have longer operating
histories, larger customer bases, greater brand recognition and significantly
greater financial, marketing and other resources than us. In addition, online
retailers may be acquired by, receive investments from or enter into other
commercial relationships with larger, well-established and well-financed
companies as use of the Internet and other online services increases. Certain of
our competitors may be able to secure merchandise from manufacturers on more
favorable terms and devote greater resources to marketing.

     Barriers to entry are minimal, and current and new competitors can launch
new sites at a relatively low cost. Increased competition may result in reduced
operating margins, loss of market share and a diminished brand franchise. We are
not sure that we will be able to compete successfully against current and future
competitors. New technologies and the expansion of existing technologies may
increase the competitive pressures on us.

OUR BUSINESS STRATEGY REQUIRES CONTINUED GROWTH OF ONLINE COMMERCE. IF ON-LINE
COMMERCE DOES NOT CONTINUE TO GROW, OUR BUSINESS COULD BE MATERIALLY ADVERSELY
AFFECTED.

     Our future revenues and any future profits are substantially dependent upon
the widespread acceptance and use of the Internet and online services as a
significant medium of commerce by consumers. Rapid growth in the use of and
interest in the Internet and online services is a recent phenomenon, and we can
not be sure that acceptance and use will continue to develop or that a
sufficiently broad base of consumers will adopt, and continue to use, the
Internet and online services as a medium of commerce. We rely on consumers who
have historically used traditional means of commerce to purchase merchandise.
For us to be successful, these

                                       16
<PAGE>
consumers must accept and utilize novel ways of conducting business and
exchanging information. Moreover, critical issues concerning the commercial use
of the Internet, such as ease of access, security, reliability, cost and quality
of service, remain unresolved and may affect the growth of Internet use or the
attractiveness of conducting commerce online.

     In addition, the Internet and online services may not be accepted as a
viable commercial marketplace for reasons relating to the adequacy of
technology. To the extent that the Internet and online services continue to
experience significant growth, we can not be sure that the infrastructure of the
Internet and online services will prove adequate to support increased user
demands. Difficulties with the telecommunications used to support the Internet
or online services also could result in slower response times and adversely
affect usage of the Internet.

OUR BUSINESS MAY BE MATERIALLY ADVERSELY AFFECTED IF THE SECURITY MEASURES WE
HAVE IMPLEMENTED TO PROTECT CONFIDENTIAL INFORMATION PROVE TO BE INADEQUATE.

     Advances in computer capabilities, new discoveries in the field of
cryptography, or other developments may result in a compromise or breach of the
algorithms used by us to protect customer transaction data. Any compromise of
our security could have a material adverse effect on us and our reputation. We
rely on encryption and authentication technology licensed from third parties to
provide the security and authentication necessary to effect secure transmission
of confidential information, such as customer credit card numbers. A party who
is able to circumvent our security measures could misappropriate proprietary
information or cause interruptions in our operations. We may be required to
expend significant capital and other resources to protect against such security
breaches or to alleviate problems caused by such breaches.

WE MAY BECOME SUBJECT TO BURDENSOME GOVERNMENT REGULATION.

     Due to the increasing popularity and use of the Internet and other online
services, it is possible that a number of laws and regulations may be adopted
with respect to the Internet covering issues such as user privacy, pricing,
content, copyrights, distribution and quality of products and services. We are
not currently subject to regulation by any domestic or foreign governmental
agency, other than regulations applicable to businesses generally, and laws or
regulations directly applicable to access to online commerce. The adoption of
any additional laws or regulations may decrease the growth of the Internet or
other online services, which could, in turn, decrease the demand for our
products and services and increase our cost of doing business, or otherwise have
a material adverse effect on us.

     Moreover, the applicability to the Internet and other online services of
existing laws in various jurisdictions governing issues such as property
ownership, sales and other taxes and personal privacy is uncertain and may take
years to resolve. In addition, as our service is available over the Internet in
multiple states and foreign countries, and as we sell to numerous consumers
residing in such states and foreign countries, such jurisdictions may claim that
we are required to qualify to do business as a foreign corporation in each such
state and foreign country. We could be subject to taxes and penalties for
failure to qualify as a foreign corporation in a jurisdiction where we are
required to do so. Any such new legislation or regulation, the application of
laws and regulations from jurisdictions whose laws do not currently apply to our
business, or the application of existing laws and regulations to the Internet
and other online services could have a material adverse effect on us.

WE MAY BE LIABLE FOR INFORMATION RETRIEVED FROM THE INTERNET.

     Due to the fact that material may be downloaded from web sites and
subsequently distributed to others, there is a potential that claims will be
made against us for negligence, copyright or trademark infringement or other
theories based on the nature and content of such material. Although we carry
general liability insurance, our insurance may not cover potential claims of
this type or may not be adequate to cover all costs incurred in defense of
potential claims or to indemnify us for all liability that may be imposed. Any
costs or imposition of liability that is not covered by insurance or in excess
of insurance coverage could have a material adverse effect on us.

                                       17

     RISKS RELATING TO THE COMMON STOCK TO BE ISSUED IN THE MERGER.

THE MERGER CONSIDERATION TO BE RECEIVED BY ADATOM STOCKHOLDERS WILL NOT BE
AFFECTED BY ANY CHANGE IN HEALTHCORE CLASS A COMMON STOCK PRICES.

     Upon completion of the merger, and subject to the HealthCore closing cash
adjustment, each share of Adatom common stock will be converted into the right
to receive approximately 2.17 shares of HealthCore class A common stock. This
exchange ratio will not be adjusted to reflect an increase or decrease in the
price of HealthCore class A common stock. The price of HealthCore class A common
stock when the merger takes place may vary from its price at the date of this
joint proxy statement/prospectus and at the date of the special meeting of our
stockholders. For example, during the twelve month period ended on September 3,
1999, the closing price of HealthCore class A common stock varied from a low of
$0.594 to a high of $3.875 and ended that period at $2.50 (see "Comparative Per
Share Market Price Information" on page 8 for further information). Variations
in the relative values of the shares of HealthCore and Adatom common stock may
be the result of changes in the business, operations or prospects of Adatom,
market assessments of the likelihood that the merger will be consummated and the
timing thereof, regulatory considerations, general market and economic
conditions and other factors. At the time of the special meeting, you will not
know the exact value of the HealthCore class A common stock that the holders of
Adatom common stock will receive when the merger is completed.

     You are urged to obtain current market quotations for HealthCore class A
common stock.

OUR PRINCIPAL STOCKHOLDERS, EXECUTIVE OFFICERS AND DIRECTORS COULD CONTROL
STOCKHOLDER VOTES AND OUR MANAGEMENT AND AFFAIRS.

     Upon completion of this merger, our executive officers, directors and 5% or
greater stockholders, and their respective affiliates, will, in the aggregate,
own approximately 68% of our outstanding common stock. As a result, they could
act together to control all matters submitted to stockholders for approval
(including the election and removal of directors and any merger, consolidation
or sale of all or substantially all of our assets). Accordingly, such
concentration of ownership may delay, defer or prevent a change in control,
impede a merger, consolidation, takeover or other business combination involving
us or discourage a potential acquirer from making a tender offer or otherwise
attempting to obtain control of us. This could, in turn, have an adverse effect
on the market price of our common stock. See "Security Ownership of Certain
Beneficial Owners, Directors and Officers."

WE MAY NOT HAVE AN ACTIVE PUBLIC MARKET FOR OUR COMMON STOCK. THE ABSENCE OF AN
ACTIVE TRADING MARKET WOULD LIKELY MAKE THE COMMON STOCK AN ILLIQUID INVESTMENT.

     After the merger, and despite the possible $5.5 million sale of equity
securities of HealthCore, the surviving company may not be able to meet the
criteria for initial listing of securities on the Nasdaq Small Cap Market. If
the surviving company does not meet the initial listing criteria which we expect
it will not, immediately following the merger, its common stock risks being
delisted. If this occurs, trading in the common stock would be conducted in the
over-the-counter market in the so-called "pink sheets" or, if available, the
"OTC Bulletin Board Service." As a result, an investor would likely find it
significantly more difficult to dispose of, or to obtain accurate quotations as
to the value of, HealthCore's securities.

                                   THE MERGER

     The discussion in this joint proxy statement/prospectus of the merger and
the principal terms of the merger agreement is subject to, and qualified in its
entirety by reference to, the merger agreement, a copy of which is attached to
this joint proxy statement/prospectus as Annex A.

GENERAL

     We are furnishing this joint proxy statement/prospectus to holders of
shares of class A and class B common stock of HealthCore and to holders of
shares of Adatom common stock, in connection with the solicitation of proxies by
the Boards of Directors of HealthCore and Adatom for use at the special meetings
of stockholders to be held on October 11, 1999 and at any adjournments or
postponements of the meetings.

     At their special meeting, the stockholders of HealthCore will be asked to
vote upon the following:

     1. to approve and adopt the Agreement and Plan of Merger, dated as of
        July 1, 1999, as amended, between HealthCore and Adatom and the
        transaction contemplated thereby, including:

          o the issuance of HealthCore common stock to holders of Adatom common
            stock pursuant to the merger;

          o the amendments to HealthCore's certificate of incorporation to
            change the name of HealthCore to Adatom.com, Inc., to eliminate the
            authorization of class B common stock, to rename the class A common
            stock to common stock, and to increase the authorized number of
            shares of HealthCore's common stock from 20 million to 50 million
            shares; and

          o the designation of a new Board of Directors for the surviving
            company;

     2. to approve the 1999 Stock Option Plan; and

     3. to approve the termination of the Amended and Restated Escrow Agreement
        dated July 31, 1997 by and among HealthCore, certain stockholders of
        HealthCore and American Stock Transfer & Trust Company dated July 31,
        1997.

     The approval of the first proposal is a condition to the consideration of
all subsequent proposals. In addition, the merger may not be consummated if
proposal number two is not approved.

     At their special meeting, the stockholders of Adatom will be asked to
approve the merger and the merger agreement.

     This joint proxy statement/prospectus also constitutes a prospectus of
HealthCore, which is a part of the Registration Statement on Form S-4 filed by
HealthCore with the Securities and Exchange Commission under the Securities Act
of 1933, in order to register the shares of HealthCore common stock to be issued
to Adatom stockholders in the merger.

     In the merger, each share of Adatom common stock issued and outstanding
immediately prior to the effective time of the merger will automatically be
converted in the merger into the right to receive approximately 2.17 shares of
HealthCore common stock, subject to adjustment and assuming termination of the
escrow agreement.

BACKGROUND OF THE MERGER

     During the third quarter of 1998, Neal Polan, Chief Executive Officer of
HealthCore and David Mullikin, President and Chief Operating Officer of
HealthCore held several meeting to review the business prospects of HealthCore.
At that time, Messrs. Polan and Mullikin believed that HealthCore could
successfully execute its business plan. During the fourth quarter of 1998, the
management of HealthCore continued to evaluate the changes in the healthcare
marketplace, new strategies to sell healthcare discount cards and the cash that
may be required to successfully market and sell Healthcare Solutions cards.
Management developed significant doubts that HealthCore could execute its
business plan with the financial resources available to it. During this time,
Mr. Polan, with the consent of the Board of Directors, began looking for
potential acquisition or merger candidates which would be a good fit for the
HealthCore business

                                       19
<PAGE>
strategy and would leverage the existing assets of HealthCore. Among the
potential acquisition candidates we evaluated was a preferred provider
organization or PPO based in New Jersey. A PPO provides employers and third
party payors, like insurance companies, access to networks of medical providers
and hospitals. HealthCore negotiated with this PPO for several months, from the
fall of 1998 into early 1999, but was unable to reach an agreement. HealthCore
continued to look for other merger or acquisition candidates to strengthen
HealthCore's business.

     During November 1998 Mr. Polan was contacted by Judson Cooper, Chairman of
SIGA Pharmaceutical. On October 15, 1998 SIGA filed a document with the
Securities and Exchange Commission disclosing its ownership of 151,000 shares of
HealthCore. On November 17, 1998, Mr. Cooper signed a confidentiality agreement
with HealthCore and requested a meeting to discuss possible business
combinations between SIGA and HealthCore. Mr. Polan met with Mr. Cooper on
several occasions and on January 6, 1999, SIGA sent a letter to HealthCore
proposing a possible combination of the two companies and outlining proposed
terms.

     On January 15, 1999, HealthCore's Board of Directors met to discuss the
SIGA letter. In order to better understand and evaluate SIGA's business, and a
possible transaction with SIGA, HealthCore retained a consultant to assist in
the evaluation. Based on the Board of Directors' analysis of a proposed
transaction with SIGA, including the review report delivered by the consultant,
the Board of Directors determined that HealthCore would not proceed with a
transaction with SIGA. During the January 15, 1999 meeting of the Board of
Directors, David Mullikin reviewed HealthCore's operations, business plans and
prospects including HealthCore's ability to execute its business plan.
Mr. Polan reviewed various alternatives to HealthCore's business plan, including
several healthcare and non-healthcare related alternatives and opportunities.
The Board determined it was appropriate for HealthCore to consider various
business alternatives and opportunities and directed the management of
HealthCore to explore alternative business opportunities.

     The Board determined that it would re-convene in approximately 60 days to
discuss and take action on whether it was in the best interest of HealthCore and
its stockholders to discontinue HealthCore's business plan and consider various
business alternatives intended to increase stockholder value. During this period
of time, HealthCore evaluated 15-20 business opportunities, including both
healthcare and non-healthcare related businesses. These included a professional
employer organization which contracts employees for employers, a mirror
manufacturer, a telephone call center business, a South American pager business,
an outpatient cancer care center business, a visiting physician service and
several others. Extensive conversations were held with many of these potential
acquisition or merger candidates.

     On January 12, 1999, Mr. Polan received a letter from Richardson and
Associates, the investment bankers representing Adatom. Mr. Polan reviewed the
letter and the executive summary that discussed the Adatom business. The next
day, Mr. Polan spent several hours on the telephone with Mr. Richard Barton,
Chairman and Chief Executive Officer of Adatom, and Adatom's investment bankers.

     Upon informal discussions with the members of the Board of Directors, Mr.
Polan reported on the Adatom meeting and the possibility of exploring Adatom
further. HealthCore was assisted by its accountants, Richard A. Eisner &
Company, LLP who provided one of its designated internet industry specialists to
help HealthCore management better understand and evaluate Adatom's business. On
January 19, 1999 Mr. Polan and a partner from Eisner had an extended telephone
conference with the Adatom management team and investment bankers. Subsequent to
this telephone conference, HealthCore management and its consultants and
advisors continued to evaluate Adatom including several meetings with Richard
Barton and an extended due diligence visit by Mr. Polan to Adatom's
headquarters. At the same time, HealthCore continued to evaluate other business
opportunities, including several Internet and electronic commerce businesses,
including an internet retailer of digital video discs, an interactive business
network, which provides business to business communication, and a business which
provides high resolution satellite imagery on the Internet. HealthCore also
evaluated a business which operates multimedia children's learning centers and
provides interactive children's software and an internet company which has
"community" web sites of special interest to different demographic groups of
people.

     On March 11, 1999 a special meeting of the Board of Directors was held to
evaluate the existing HealthCore business and several acquisition or merger
opportunities. Mr. Mullikin presented an overview of the HealthCore business and
the likelihood of its ability to successfully execute its business plan. The
Board

                                       20
<PAGE>
concluded that HealthCore should seek merger candidates as the most viable means
of maximizing stockholder value and should determine how to proceed with the
sale or discontinuance of its healthcare business. Mr. Polan reviewed and
evaluated several healthcare opportunities for the Board, none of which were
determined by the Board to be viable merger or acquisition candidates.
Mr. Polan also reviewed opportunities in unrelated industries including Internet
opportunities. Summaries of three potential merger opportunities were presented
to the Board; all were internet or internet related. After evaluation of the
three potential opportunities and analysis of the probability of completing a
transaction, the potential of the merger candidates' businesses, the cash
requirements of the potential merger candidates and the potential to provide
HealthCore stockholders with the most value, the Board authorized Mr. Polan to
use his best efforts to negotiate a transaction with Adatom.

     During the next several weeks, HealthCore negotiated a transaction with
Adatom while continuing to perform a due diligence review of its business.
During this time, HealthCore retained Jessup & Lamont to advise on the merger.
On April 27, 1999 HealthCore executed a letter of Intent to merge with Adatom.
On July 1, 1999 HealthCore entered into an Agreement and Plan of Merger with
Adatom.

HEALTHCORE'S REASONS FOR THE MERGER; RECOMMENDATION OF ITS BOARD OF DIRECTORS

     HealthCore's Board of Directors has unanimously approved the merger and the
merger agreement and recommends that the HealthCore stockholders approve the
merger and merger agreement and the related transactions including the issuance
of stock to the Adatom stockholders. HealthCore's Board believes the
consideration to be paid by HealthCore is fair from a financial point of view
and that the merger is in the best interest of its stockholders. The Board
considered the advice and analysis of management, its financial advisor, Kaufman
Bros., L.P., its investment banker, Jessup and Lamont, and its legal counsel and
accountants.

     The Board also considered the following potential benefit of the merger and
the discontinuance of its healthcare discount business to the HealthCore
stockholders:

          o To date, HealthCore has not been successful in executing its
            business plan. Management believed that there may not have been
            sufficient capital reserve in HealthCore to fulfill its business
            plan and the Board of Directors was uncertain of HealthCore's
            ability to raise more money.

          o Healthcare regulations throughout the country continued to change
            which may have had a continued adverse affect on HealthCore's
            business. For example, many states have begun to require HMOs to
            include chiropractic services as a mandatory part of their health
            plan to their members. As well, there have been proposals and
            discussions to offer drug coverage to Medicare recipients which had
            not been included in Medicare before.

          o Adatom's stockholders have invested almost $2 million to develop its
            business and the Board believes Adatom is well positioned among
            Internet companies to begin its efforts to commercialize its
            business.

          o Adatom has experienced management in Mr. Barton and
            Mr. Jagannathan. Mr. Barton has demonstrated in the past successful
            leadership of business.

          o The market capitalization of the combined company could be larger
            than the market capitalization of HealthCore, and if so it might
            create the opportunity for increased research coverage by financial
            analysts and increased institutional ownership as well as a larger
            trading "float" that could provide increased liquidity for
            stockholders. As a result, the combined company would likely have
            greater access to debt and equity financing.

          o The financial terms of the merger agreement, including an exchange
            ratio that provides relative certainty about the number of shares of
            HealthCore common stock that will be issued in the merger.

          o The presentations and financial analysis of Kaufman Bros., L.P.'s
            opinion dated August 30, 1999, that, as of the date of the opinion
            and based upon and subject to certain matters, the merger and

                                       21
<PAGE>
            the transactions contemplated thereby were fair, from a financial
            point of view, to the HealthCore stockholders;

          o The potential that Adatom might have more success raising the money
            it may need to fulfill its business plan than HealthCore would for
            its business.

          o The potential positive impact of the merger on the general long-term
            interests, prospects and objectives of HealthCore and its
            stockholders.

     HealthCore's Board also considered certain countervailing factors in its
discussions of the merger. These factors are described under "Risk Factors" on
page 12.

     HealthCore's Board of Directors, after review of all of the information
available to it, determined that the benefits of the merger and related
transactions outweighed the countervailing factors.

     HealthCore's Board of Directors has unanimously approved the merger and the
merger agreement and recommends that the HealthCore stockholders approve the
merger and merger agreement and the related transactions including the issuance
of stock to the Adatom stockholders.

      THE HEALTHCORE BOARD UNANIMOUSLY FOUND THE MERGER AND MERGER AGREEMENT
 INCLUDING THE ISSUANCE OF HEALTHCORE COMMON STOCK TO ADATOM STOCKHOLDERS TO BE
 IN THE BEST INTERESTS OF THE HEALTHCORE STOCKHOLDERS AND RECOMMENDS THAT THE
 HEALTHCORE STOCKHOLDERS VOTE "FOR" APPROVAL OF THE MERGER.

OPINION OF THE HEALTHCORE BOARD OF DIRECTORS' FINANCIAL ADVISOR

     The HealthCore Board retained Kaufman Bros., L.P. to render to the Board a
fairness opinion in connection with the Adatom Merger (the "Kaufman Opinion").
On August 29, 1999, Kaufman delivered to HealthCore's Board its oral opinion
(which opinion was subsequently confirmed by delivery of a written opinion,
dated August 30, 1999) to the effect that, as of such date and based upon and
subject to certain factors and assumptions stated therein, the consideration to
be paid in the Merger to Adatom's shareholders in the form of Common Stock of
HealthCore was fair, from a financial point of view, to the shareholders of
HealthCore.

     Kaufman is a investment banking firm specializing in the technology
industry which, as a part of its investment banking business, regularly engages
in the evaluation of businesses and their securities in connection with mergers
and acquisitions, negotiated underwritings, secondary distributions of
securities, private placements of public and private companies and valuations
for corporate and other purposes. HealthCore's Board selected Kaufman based on
its independence and experience. Kaufman in the normal course of its business,
may hold and actively trade in securities of HealthCore for its own account or
for the accounts of its customers and, accordingly, may at any time hold a long
or short position in such securities.

      THE FULL TEXT OF THE KAUFMAN OPINION, WHICH SETS FORTH A DESCRIPTION OF
 THE ASSUMPTIONS MADE, GENERAL PROCEDURES FOLLOWED, FACTORS CONSIDERED AND
 LIMITATIONS OF THE REVIEW UNDERTAKEN, IS ATTACHED HERETO AS ANNEX B AND IS
 INCORPORATED HEREIN BY REFERENCE. THE SUMMARY OF THE KAUFMAN OPINION SET FORTH
 IN THIS PROXY STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY REFERENCE
 TO THE FULL TEXT OF SUCH OPINION.

     The summary set forth below does not purport to be a complete description
of the analyses underlying the Kaufman Opinion or the presentation made by
Kaufman to the HealthCore Board. The preparation of a fairness opinion is a
complex analytical process involving various determinations as to the most
appropriate quantitative and qualitative factors to consider in the particular
circumstances and, therefore, such an opinion is not readily susceptible to
partial analysis or summary description. In arriving at its opinion, Kaufman did
not attribute any particular weight to any analysis or factor but instead made
qualitative judgments as to the significance and relevance of each analysis and
factor. Accordingly, Kaufman's opinion should be considered

                                       22
<PAGE>
as a whole and particular analyses or portions of its judgments, without
considering all of the factors collectively, may create an incomplete view of
the process underlying the Kaufman Opinion. In its analysis, Kaufman made
numerous assumptions with respect to industry performance, existing market
conditions, general business and economic conditions, the proposed terms of the
transaction and other matters, many of which were beyond the control of Adatom
and HealthCore. Any estimates contained in arriving at the opinion are not
necessarily indicative of actual values or predictive of future results or
values, which may be significantly more or less favorable than as set forth
therein. In addition, analyses relating to the value of businesses do not
purport to be appraisals or reflect the prices at which businesses actually may
be sold or the price at which stock would be bought/sold in a public offering.
Accordingly, such analyses and estimates are inherently subject to substantial
uncertainty.

     HealthCore agreed, among other things, to pay Kaufman $65,000 for its
investment banking services in connection with rendering the Kaufman Opinion. In
addition, HealthCore agreed to reimburse Kaufman for its reasonable
out-of-pocket expenses, including the reasonable fees and disbursements of
Kaufman's legal counsel incurred in connection with Kaufman's engagement.
HealthCore also agreed to indemnify Kaufman and its officers, employees and
agents for any losses incurred in connection with its engagement, including
certain liabilities under the Federal securities laws.

     In arriving at its opinion, Kaufman assumed and relied upon the accuracy
and completeness of the material and other information provided to it by Adatom
and HealthCore without assuming any responsibility for independent verification
of such information and further relied upon the assurances of the managements of
Adatom and HealthCore that they are not aware of any facts or circumstances that
would make such information inaccurate or misleading. With respect to the
financial projections of Adatom, Kaufman assumed that such projections were
reasonably prepared on a basis reflecting the best currently available estimates
and judgment of Adatom's management as to the future financial performance of
Adatom and that Adatom will perform substantially in accordance with such
projections. In arriving at its opinion, Kaufman visited the Mipitas, California
headquarters of Adatom but did not conduct a physical inspection of such
facility. Kaufman did not make or obtain any evaluations or appraisals of the
assets or liabilities of Adatom or HealthCore, nor was Kaufman furnished with
any such evaluations or appraisals.

     Kaufman has relied on the information contained in the materials described
in the Kaufman Opinion which describes the Merger as a result of which the
HealthCore will issue 10,689,489 shares of its Common Stock to Adatom's
shareholders, an exchange ratio of 2.17 shares of Common Stock for each share of
Adatom's common stock (the "Exchange Ratio"), at which time Adatom's
shareholders will hold approximately 77.5% of the combined company's outstanding
Common Stock, subject to adjustment. The Exchange Ratio will be increased by
 .0179 of a share or an aggregate of 195,000 shares of Common Stock for every
$100,000 by which the HealthCore's cash assets fail to meet the $2.85 million
threshold at the time of closing.

     In connection with the Kaufman Opinion, Kaufman reviewed and analyzed,
among other things:

          o The Agreement and Plan of Merger dated July 1, 1999, by and between
            the Company and Adatom;

          o a draft of this Form S-4 Registration Statement and Proxy;

          o certain documents and reports filed by HealthCore with the
            Securities and Exchange Commission;

          o certain internal information and documents relating to the Company
            and Adatom provided to us by their respective managements, including
            historical financial information and financial forecasts;

          o the reported prices and trading activity of the Company's common
            stock;

          o the financial and business prospects for the merged entity and the
            industry in which it competes;

                                       23
<PAGE>

          o certain publicly available information concerning certain other
            companies engaged in businesses which it believed to be comparable
            to Adatom and the trading markets for such other companies'
            securities;

          o information concerning recent private equity investments in
            pre-public e-commerce companies we believe to be comparable to
            Adatom; and

          o information concerning certain other business transactions which we
            believe to be relevant to the Merger.

     In addition, Kaufman had discussions with certain officers and employees of
Adatom and HealthCore concerning their respective businesses, operations,
assets, financial conditions and prospects and potential strategic benefits from
a combination of the businesses of Adatom and HealthCore, and undertook such
other studies, analyses and investigations as Kaufman deemed appropriate.

     In performing its analysis, Kaufman took into account a number of factors
relating to HealthCore, Adatom and the Merger. Among these factors pertaining to
HealthCore were the current status of any business activity, its current
financial position, including cash balance, and the trading activity of its
Common Stock both before and after the announcement of the Merger. In performing
its analysis with respect to Adatom, Kaufman took into account, among other
things, Adatom's current business opportunities and growth plans, its small base
of historical revenue, Adatom's participation in the fast growing and rapidly
changing online retailing industry and its need for additional capital.

     Kaufman noted that its opinion was necessarily based upon financial,
economic, market and other conditions as they existed and could be evaluated by
Kaufman on, and the information made available to it as of, the date of its
opinion. Kaufman has disclaimed any undertaking or obligation to advise any
person of any change in any fact or matter affecting its opinion that is brought
to its attention after the date of its opinion. Although Kaufman evaluated the
consideration paid to the shareholders of Adatom from a financial point of view,
it was not asked to and did not recommend the specific consideration payable in
the Merger, which was determined through negotiations between HealthCore and
Adatom.

     The Kaufman Opinion is for the information of HealthCore's Board of
Directors for its use in evaluation the fairness from a financial point of view
to the shareholders of HealthCore of the consideration to be paid in the Merger
to shareholders of Adatom. Such opinion does not constitute a recommendation as
to any action the Board of Directors or any shareholder of HealthCore should
take in connection with the Merger or any aspect thereof. The Kaufman Opinion is
not an opinion as to the structure, terms or effect of any aspect of the Merger
or of any transactions contemplated in connection therewith or as to the merits
of the underlying decision to enter into the Merger or any such transaction.

     Conclusion.  Based on and subject to the foregoing, Kaufman delivered its
opinion, as investment bankers, that, as of August 30, 1999, the consideration
to be paid to the Adatom shareholders in the merger with HealthCore was fair
from a financial point of view, to HealthCore's shareholders.

ADATOM'S REASONS FOR THE MERGER; RECOMMENDATION OF ITS BOARD OF DIRECTORS

     The Adatom Board believes that the merger will have two principal benefits
to Adatom. First, Adatom will have access to the cash and cash equivalents owned
by HealthCore to expand Adatom's business. Second, it will be easier (and less
dilutive to Adatom's stockholders) to raise capital necessary for the growth of
Adatom's business as a public company. The Adatom Board has approved the merger
and the transactions contemplated thereby and recommends approval of the merger
by the stockholders of Adatom. In reaching its conclusion, the Board considered
the structure of the merger, the fact that Mr. Neal Polan will be added to the
Board and have an employment agreement with Adatom, the results of its due
diligence, the results of a review of alternatives to the merger and the pro
forma financial information.

      THE ADATOM BOARD UNANIMOUSLY FOUND THE MERGER TO BE ADVISABLE AND
 RECOMMENDS THAT THE ADATOM STOCKHOLDERS VOTE "FOR" APPROVAL OF THE MERGER.

                                       24
<PAGE>
FORM OF THE MERGER

     Subject to the terms and conditions of the merger agreement and in
accordance with the Delaware General Corporation Law, at the effective time,
Adatom will be merged with and into HealthCore. HealthCore will be the surviving
company in the merger and will be renamed Adatom.com, Inc. The certificate of
incorporation of HealthCore, will be amended, and adopted as the certificate of
incorporation of the surviving company in the merger and the HealthCore By-laws
will be adopted as the by-laws of the surviving company. At the effective time,
HealthCore will change its name to Adatom.com, Inc.

MERGER CONSIDERATION

     At the effective time, each outstanding share of Adatom common stock will
be converted into the right to receive approximately 2.17 fully paid and
nonassessable shares of HealthCore common stock, subject to adjustment and
assuming termination of the escrow agreement by all parties to that agreement.
The number of shares to be received by Adatom stockholders for each share of
Adatom common stock they own will be increased by an additional .018 of a share
or an aggregate of approximately 195,000 shares for every $100,000 by which the
Healthcare cash assets fail to meet the $2.80 million threshold at the time of
closing. See "The Merger Agreement--Consideration To Be Received In The Merger."
As of the effective time, the shares of Adatom common stock will no longer be
outstanding and will automatically be cancelled and cease to exist and each
holder of shares of Adatom common stock will cease to have any rights in respect
of those shares, except the right to receive the consideration set forth in the
immediately preceding sentence. See "--Conversion of Shares; Procedures for
Exchange of Certificates." The exchange ratio was determined through
arm's-length negotiations between Adatom and HealthCore.

AMENDMENTS TO HEALTHCORE'S CERTIFICATE OF INCORPORATION

     HealthCore presently is authorized to issue the following capital stock:

          o 20,000,000 shares of common stock, consisting of 19,640,000 shares
     of class A common stock, $.01 par value; and 360,000 shares of class B
     common stock, $.01 par value; and
          o 5,000,000 shares of preferred stock, $.01 par value.

     On the record date, there were 3,183,000 shares of class A common stock
issued and outstanding, 216,000 shares of class B common stock issued and
outstanding and no shares of preferred issued and outstanding.

     The Board of Directors of HealthCore has approved, subject to adoption by
its stockholders, an amendment to Article FOURTH of HealthCore's Amended and
Restated Certificate of Incorporation which would make the following changes in
the capital structure of HealthCore:

          o eliminate the authorization of class B common stock and rename the
            class A common stock to common stock
          o increase the authorized number of shares of common stock to
            50 million shares.

     In the merger, Adatom stockholders will receive approximately 2.17 shares
of HealthCore common stock for each share of Adatom common stock they own,
subject to adjustment and assuming termination of the escrow agreement. This
equals an aggregate of 10,689,489 shares of HealthCore common stock. This
calculation gives effect to the issuance of an additional 2,511,620 shares of
Adatom common stock before the merger and assumes exercise of 396,000 options
and warrants to purchase HealthCore Class A common stock at an exercise price
not greater than $1.25 per share and exercise of a warrant to purchase Adatom
common stock which will be exercisable to purchase 50,661 shares of Adatom.com,
Inc. common stock. On a fully diluted basis there would be 17,583,389 shares of
common stock of the combined company outstanding. The number of shares to be
received by Adatom stockholders for each share of Adatom common stock they own
will be increased by an additional .018 of a share or an aggregate of
approximately 195,000 shares for every $100,000 by which the Healthcare cash
assets fail to meet the $2.80 million threshold at the time of closing.
HealthCore has agreed to issue Jesup & Lamount Securities, at the close of the
merger, warrants to purchase 200,000 shares at $1.00 per share. In addition,
HealthCore has outstanding warrants to purchase an aggregate of 3,590,500 shares
at a weighted average price of $6.45 per share. These warrants are not given
effect in the

                                       25
<PAGE>
negotiation of the exchange ratio in the merger. The increase in the number of
authorized shares of HealthCore common stock to 50 million is required to
provide HealthCore sufficient stock to consummate the merger, issue shares upon
exercise of stock options, issue stock dividends and for other corporate
purposes.

     The Board of Directors has proposed the elimination of the authorization of
the class B common stock. The class B common stock has voting rights of five
votes per share, as opposed to the one vote per share voting rights of the
class A common stock. In connection with the merger, the sole owner of class B
common stock has agreed to convert all of the shares of HealthCore class B
common stock held by him into HealthCore class A common stock in accordance with
the relevant provisions of HealthCore's Certificate of Incorporation. Once this
occurs, there will be no outstanding class B common stock, and the distinction
between class A and class B will become meaningless.

     A copy of the form of the Amendment to the Certificate of Incorporation is
attached as Exhibit C.

CONVERSION OF SHARES; PROCEDURES FOR EXCHANGE OF CERTIFICATES

     The conversion of Adatom common stock into HealthCore common stock will
occur automatically at the effective time. Upon each Adatom stockholder's
surrender of a certificate representing Adatom common stock to the surviving
company for cancellation, each such Adatom stockholder will be entitled to
receive certificates representing shares of the common stock of the surviving
company, rounded up to the nearest whole number.

      ADATOM STOCKHOLDERS AND HEALTHCORE STOCKHOLDERS SHOULD NOT RETURN STOCK
 CERTIFICATES WITH THE ENCLOSED PROXY CARD.

     Holders of certificates previously representing Adatom common stock will
not be paid dividends or distributions on the HealthCore common stock into which
such shares have been converted with a record date after the effective time
until such certificates are surrendered for exchange. When such certificates are
surrendered, any unpaid dividends or distributions will be paid without
interest.

     In the event of a transfer of ownership of Adatom common stock which is not
registered in the records of Adatom, a certificate representing the proper
number of shares of HealthCore common stock may be issued and any cash or other
dividends or distributions to be paid upon surrender of the certificate may be
paid to a person other than the person in whose name the certificate so
surrendered is registered if the certificate is presented, accompanied by all
documents required to evidence the transfer and the person requesting such
issuance pays any transfer or other taxes required for the issuance of shares to
a person other than the registered holder of such certificate or establishes to
the satisfaction of HealthCore that such tax has been paid or is not applicable.

     All shares of HealthCore common stock issued upon conversion of shares of
Adatom common stock, will be deemed to have been issued in full satisfaction of
all rights pertaining to such shares of Adatom common stock, subject, however,
to HealthCore's obligation to pay any dividends or make any other distributions
with a record date prior to the effective time that may have been declared by
Adatom on such shares of Adatom common stock and which remain unpaid at the
effective time.

EFFECTIVE TIME

     The effective time will be the time of the filing of the Certificate of
Merger with the Secretary of State of the State of Delaware or such later time
as is agreed upon by Adatom and HealthCore and specified in the Certificate of
Merger. The filing of the Certificate of Merger will occur as soon as
practicable following the closing of the merger. The closing will occur no later
than the first business day after satisfaction or waiver of the conditions to
the consummation of the merger set forth in the merger agreement unless another
date is agreed to in writing by Adatom and HealthCore.

                                       26

FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

     We expect that the exchange of shares by Adatom stockholders will be
tax-free to Adatom stockholders for federal income tax purposes. However, this
expectation is based on laws, regulations, rulings and decisions in effect on
the date hereof, all of which are subject to change (possibly with retroactive
effect) and to differing interpretations. This discussion does not address all
aspects of federal taxation that may be relevant to particular Adatom
stockholders in light of their personal circumstances or to Adatom stockholders
subject to special treatment under the Internal Revenue Code of 1986, including,
without limitation, banks, tax-exempt organizations, insurance companies,
dealers in securities or foreign currency, Adatom stockholders who received
their Adatom common stock through the exercise of employee stock options or
otherwise as compensation, Adatom stockholders who are not U.S. persons (as
defined in Section 7701(a)(30) of the Internal Revenue Code) and Adatom
stockholders who hold Adatom common stock as part of a hedge, straddle or
conversion transaction. In addition, the discussion does not address any state,
local or foreign tax consequences of the merger.

      EACH HOLDER OF ADATOM COMMON STOCK IS URGED TO CONSULT ITS TAX ADVISOR
 WITH RESPECT TO THE PARTICULAR TAX CONSEQUENCES OF THE MERGER TO SUCH
 HOLDER.

REGULATORY AND THIRD PARTY APPROVALS

     Third-Party Approvals.  Each of HealthCore and Adatom is a party to certain
contracts and other agreements. Consummation of the merger may require the
consent of, or waiver from, the other parties to some of these agreements.
HealthCore and Adatom do not believe that the failure to obtain such consents,
approvals or waivers would have a material adverse effect on HealthCore.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

     Certain stockholders of HealthCore class A and class B common stock are
subject to an escrow agreement, which restricts the stockholders from
transferring those and to forfeiture unless certain market price thresholds of
operating performance-based criteria of HealthCore are met. None of these
thresholds or criteria has been met to date. If these thresholds or criteria are
not met by October 2000, the shares subject to the escrow agreement will be
returned to HealthCore and cancelled. HealthCore's management believed that
under its operations of the health care benefits business, it was unlikely that
these thresholds or criteria of the escrow agreement would be met. In connection
with the merger, all holders of shares in escrow agreed to terminate the escrow
agreement, subject to stockholder approval of the termination, and under the
termination agreement have agreed to surrender 80% of their shares and will
receive at the time of the merger or after if the termination occurs subsequent
to the merger 20% of their shares held in escrow free of the risk of forfeiture
and other transfer restrictions imposed by the escrow agreement.

     In connection with the merger, Richard Barton, the President and the CEO of
Adatom, who now holds a majority of the Adatom shares, will enter into an
employment agreement with the surviving company. The employment agreement will
be for a term of three years, and will provide for an annual salary of $200,000,
a bonus in the amount of $100,000 tied to the performance of the surviving
company, a vehicle, reimbursement of business expenses, health insurance and
related benefits.

     At the closing of the merger, HealthCore will terminate the employment of
David Mullikin, President of HealthCore. Mr. Mullikin will receive a severance
package from HealthCore which provides for a payment of $100,000 plus 100,000
options to purchase shares of HealthCore at $.10 per share. This severance is in
lieu of the severance to which he was previously entitled under his existing
employment agreement, namely $150,000 reduced by 50% of any compensation he
receives from other employment during the one year period following termination,
but in no event less than $75,000. Mr. Mullikin will also receive registration
rights for the shares of stock underlying those options. If HealthCore files a
registration statement with the Securities and Exchange Commission after the
closing of the merger, Mr. Mullikin may include his shares in

                                       27
<PAGE>
that registration statement. If HealthCore does not file a registration
statement within 120 days, then Mr. Mullikin may demand that HealthCore register
his shares on an appropriate registration statement.

     Neal J. Polan, HealthCore's Chairman of the Board, will enter into a
two-year employment agreement with the Adatom which provides for an annual
salary of $50,000, reimbursement of business expenses, health insurance and
related benefits. Mr. Polan will be required to work up to 60 hours per month as
an advisor for the surviving company in mergers, acquisitions and strategic
alliances. In connection with the employment agreement, Mr. Polan will receive a
right to purchase stock in Adatom in an amount equal to that number of Adatom
shares convertible into 350,000 shares of HealthCore common stock in the merger
in exchange for a promissory note in the amount of $320,760. As partial
consideration for his services rendered under the employment agreement, the
promissory note will be forgiven six months after the closing date of the
merger.

     On April 27, 1999, Mr. Polan agreed to amend his existing employment
agreement with HealthCore, dated September 30, 1998, to permit HealthCore to
terminate his employment without cause and to revise the terms of his severance
package. Mr. Polan's original employment agreement provides that in the event
that Mr. Polan's employment is terminated without cause, HealthCore would be
required to pay him all sums that would have been paid under the agreement. The
amended employment agreement reduces the amount of severance upon termination of
employment and provides that HealthCore would only have to pay Mr. Polan the
lesser of $150,000 or 60% of the remaining value of the contract at the time of
termination. In consideration for agreeing to the amended employment agreement,
Mr. Polan received 165,000 shares of HealthCore class A common stock.

     Mr. Polan owns shares which are subject to the escrow agreement and will be
treated identical to the shares held in escrow by the other escrow stockholders
described above.

     Mr. Polan will receive registration rights covering 367,800 shares,
including 142,000 shares underlying warrants.

     In September 1997, in connection with his employment with HealthCore,
Mr. Polan received a warrant to purchase 142,000 shares of HealthCore common
stock at $1.00 per share. The warrant becomes exercisable if certain market
price thresholds or operating performance-based criteria of HealthCore are met.
In connection with the merger, Mr. Polan entered into an agreement with
HealthCore to exchange that warrant for 28,400 shares of HealthCore common stock
at the closing of the merger.

     On July 8, 1999 Eli Levitin, a director of HealthCore, purchased $50,000 of
convertible debt of Adatom through Jesup & Lamont Acquisition Corporation, a
company in which Mr. Levitin has a 10% interest. These securities will be
converted into shares of Adatom common stock immediately prior to the merger and
will then be exchanged for 50,661 shares of common stock of Adatom.com, Inc.
pursuant to the merger.

     In connection with the merger, all holders of Adatom securities, Neal
Polan, and David Mullikin, have entered into lock-up agreements that prohibit
transfer of some or all of their respective shares of Adatom.com, Inc.'s common
stock for up to a period of six months. The holders of Adatom securities have
agreed to a lock-up covering all of their shares of Adatom.com, Inc. Mr. Polan
has agreed to lock-up 796,800 shares, including 167,000 shares issuable upon
exercise of warrants and Mr. Mullikin has agreed to lock up the 100,000 shares
underlying the options being issued to him upon termination of employment.
Mr. Polan's lock-up agreement differs slightly from those of the other parties
to lock-up agreements in that it provides that 125,000 of his shares, which
represents a portion of the shares he owned prior to the merger, will be subject
to the lock-up agreement for a period of two months following the closing and
the remaining 671,800 shares will be subject to the lock-up agreement for a
period of six months following the closing. Certain non-affiliates of Adatom,
who will receive an aggregate of 557,272 shares of HealthCore in the merger,
including 50,661 shares issuable upon exercise of a warrant, will be freed from
the lock-up restrictions with respect to 20% of those shares, commencing two
months after the closing of the merger.

RESTRICTIONS ON RESALES BY AFFILIATES

     Affiliates of Adatom.  The shares of HealthCore stock to be issued to
Adatom stockholders in the merger have been registered under the Securities Act.
These shares may be traded freely and without restriction, other than those
restrictions imposed by lock-up agreements, by those stockholders not deemed to

                                       28
<PAGE>
be "affiliates" of Adatom as that term is defined under the Securities Act. An
affiliate of a corporation, as defined by the rules promulgated under the
Securities Act, is a person who directly or indirectly, through one or more
intermediaries, controls, is controlled by, or is under common control with,
that corporation. Any transfer by an affiliate of Adatom must be one permitted
by the resale provisions of Rule 145 promulgated under the Securities Act or as
otherwise permitted under the Securities Act. These restrictions are expected to
apply to the executive officers and directors of Adatom.

                           THE STOCKHOLDERS' MEETINGS

PURPOSE, TIME AND PLACE

     This joint proxy statement/prospectus is being furnished to you in
connection with the solicitation of proxies by the Adatom Board and HealthCore
Board from holders of Adatom common stock and HealthCore class A and class B
common stock for use at special meetings to be held on October 11, 1999 and at
any adjournments or postponements thereof. The HealthCore special meeting will
take place at the Marriott Hotel, Kansas City Airport, 775 Brasilia Avenue,
Kansas City, Missouri 64153 at 11:00 a.m., local time. The Adatom special

     1. to approve and adopt the Agreement and Plan of Merger, dated as of
        July 1, 1999, as amended, between HealthCore and Adatom and the
        transaction contemplated thereby, including:

          o the issuance of HealthCore common stock to holders of Adatom common
            stock;

          o the amendments to HealthCore's certificate of incorporation to
            change the name of HealthCore to Adatom.com, Inc., to eliminate the
            authorization of class B common stock, to rename the class A common
            stock to common stock, and to increase the authorized number of
            shares of HealthCore's common stock from 20 million shares to
            50 million shares; and

          o the designation of a new Board of Directors for the surviving
            company;

        by and among American Stock Transfer & Trust Company, HealthCore and
        certain stockholders of HealthCore dated July 31, 1997.

     The approval of the first proposal is a condition to the consideration of
all subsequent proposals. In addition, the merger may not be consummated if
proposal number two is not adopted.

     At the Adatom special meeting, the holders of Adatom common stock will be
asked to consider and vote upon a proposal to approve the merger as set forth in
the merger agreement.

RECORD DATE; VOTING POWER

     HealthCore.  The HealthCore Board has fixed the close of business (5:00
p.m., local time) on September 10, 1999, as the record date for determining the
holders of HealthCore class A and class B common stock entitled to notice of,
and to vote at, the HealthCore special meeting. At the close of business on the
record date, 3,183,000 shares of HealthCore class A common stock were issued and
outstanding and entitled to vote at the HealthCore special meeting and 216,000
shares of HealthCore class B common stock were issued and outstanding and
entitled to vote at the HealthCore special meeting. Only holders of record of
HealthCore class A and class B common stock at the close of business on the
record date will be entitled to notice of, and to vote at, the HealthCore
special meeting. Holders of record of HealthCore class A common stock are
entitled to one vote per share on any matter which may properly come before the
HealthCore special meeting. Holders of class B common stock are entitled to five
votes per share on any matter which may properly come before the HealthCore
special meeting. Votes may be cast at the HealthCore special meeting in person
or by proxy. See "The Stockholders' Meeting--Voting of Proxies."

     The presence at the HealthCore special meeting, either in person or by
proxy of the holders of a majority of the voting power represented by the
HealthCore class A and class B common stock as a single class is necessary to
constitute a quorum in order to transact business at the HealthCore special
meeting. In the event that a quorum is not present at the HealthCore special
meeting, such meeting will be adjourned or postponed in order to solicit
additional proxies.

     Adatom.  The Adatom Board has fixed the close of business (5:00 p.m., local
time) on September 13, 1999, as the record date for determining the holders of
Adatom common stock entitled to notice of, and to

                                       30
<PAGE>
vote at, the Adatom special meeting. Only holders of record of Adatom common
stock at the close of business on the record date will be entitled to notice of,
and to vote at, the Adatom special meeting.

     At the close of business on the record date, 2,384,600 shares of Adatom
common stock were issued and outstanding and entitled to vote at the Adatom
special meeting. Holders of record of Adatom common stock are entitled to one
vote per share on any matter which may properly come before the Adatom special
meeting. Votes may be cast at the Adatom special meeting in person or by proxy.
See "-- Voting of Proxies."

     The presence at the Adatom special meeting, either in person or by proxy of
the holders of a majority of the outstanding Adatom common stock entitled to
vote, is necessary to constitute a quorum in order to transact business at the
Adatom special meeting.

VOTES REQUIRED

     HealthCore.  Approval by HealthCore stockholders of the merger agreement
requires the affirmative vote of more than 50% of the votes of class A common
stock and class B common stock outstanding on the record date voting as a single
class or 2,131,501 votes of a total of 4,263,000 votes of the combined classes.
That approval will include the issuance of HealthCore common stock, the
amendments to HealthCore's certificate of incorporation and the designation of a
new board of directors.

     In addition, unless waived by Adatom, the merger must be approved by more
than 50% of the shares of class A common stock outstanding on the record date
excluding the 165,000 shares of class A common stock beneficially owned by
Mr. Polan other than proxies he has obtained from non-family members, or
1,509,001 shares of a total of 3,018,000 shares of class A common stock.

     While HealthCore's Board of Directors does not believe that stockholder
approval was required for the sale of its healthcare benefits business, approval
of the merger agreement by HealthCore's stockholders will constitute
ratification of the sale.

     The approval of the 1999 Stock Option Plan will require the affirmative
vote of more than 50% of the votes of class A and class B common stock voting as
a single class, represented in person or by proxy at the special meeting.

     Approval of the termination of the escrow agreement will require the
approval of at least two-thirds of the shares of class A common stock
outstanding on the record date excluding all shares of class A common stock held
by escrow stockholders whether or not those shares are subject to the escrow
agreement.

     In the event the stockholders of HealthCore fail to approve the termination
of the escrow agreement, Adatom stockholders have agreed to vote all of their
shares of the combined company to approve the termination of the escrow
agreement at the first annual or special meeting of the stockholders of the
combined company following the merger.

     Under Delaware law, in determining whether the proposal to approve and
adopt the merger agreement and the transactions contemplated thereby have
received the requisite number of affirmative votes, abstentions will be counted
and have the same effect as a vote against the proposals. Brokers who hold
shares of HealthCore common stock as nominees will not have the discretionary
authority to vote such shares in the absence of instructions from the beneficial
owners thereof. Any shares which are not voted because the nominee-broker lacks
discretionary authority will be counted and have the same effect as a vote
against the proposals.

     Adatom.  Approval by Adatom stockholders of the merger and the merger
agreement will require the approval of more than 50% of the shares of Adatom
common stock outstanding on the record date, or 1,192,301 shares of the
2,384,600 shares outstanding. All Adatom stockholders have agreed to vote for
the merger. Under California law, in determining whether the proposal to approve
the merger has received the requisite number of affirmative votes, abstentions
will be counted and have the same effect as a vote against the proposal. Brokers
who hold shares of Adatom common stock as nominees will not have discretionary
authority to vote such shares in the absence of instructions from the beneficial
owners thereof. Any shares

                                       31
<PAGE>
which are not voted because the nominee-broker lacks such discretionary
authority will be counted and have the same effect as a vote against the
proposal.

SHARE OWNERSHIP OF MANAGEMENT

     HealthCore.  On the record date, directors and executive officers of
HealthCore and their affiliates may be deemed to be the beneficial owners of
187,000 shares of HealthCore class A common stock or approximately 5.9% of the
HealthCore class A common stock outstanding on the record date. Excluding
Mr. Polan's 165,000 shares of class A common stock, these other directors and
executive officers and their affiliates own approximately 22,000 shares of less
than 1% of the 3,018,000 shares of class A common stock so outstanding.

     On the record date, Neal Polan, Chairman and Chief Executive Officer of
HealthCore may be deemed to be the beneficial owner of all of the 216,000 shares
of HealthCore class B common stock, outstanding. Accordingly, on the record
date, directors and executive officers of HealthCore and their affiliates held
approximately 29.7% of the voting power of the combined class A and class B
common stock. This voting power percentage does not take into account the shares
of class A common stock that Mr. Polan has the right to vote under proxies given
to him by the escrow stockholders, as described below.

     Neal Polan has agreed to vote all his 165,000 shares of class A common
stock and 216,000 shares of class B common stock in favor of the merger and
related transactions. Class B common stock has voting rights of five votes per
share.

     In addition, all the other directors and executive officers of HealthCore
have indicated that they intend to vote the class A common stock owned by them
for all the HealthCore proposals detailed in this proxy statement.

     All escrow stockholders have given Neal Polan a proxy to vote all shares of
class A common stock they own, including all shares held in escrow, in favor of
all proposals that come before the special meeting. After giving effect to these
proxies, the executive officers and directors of HealthCore and their affiliates
have the right to vote at least 47% of the voting power of the combined class A
and class B common stock.

     Adatom.  On the record date, there were four holders of Adatom common stock
outstanding on the record date. These holders, all of whom are directors of
Adatom, have agreed to vote the Adatom common stock owned by them for the
approval of the merger and the merger agreement.

VOTING OF PROXIES

     Shares represented by properly executed proxies received in time for a
special meeting will be voted at such special meeting in the manner specified by
such proxies. HealthCore and Adatom stockholders should be aware that, if your
proxy is properly executed but does not contain voting instructions, your proxy
will be voted FOR approval of the merger. It is not expected that any matter
other than as described herein will be brought before the special meetings. If
other matters are properly presented before the special meetings, the persons
named in such proxy will have authority to vote in accordance with their
judgment on any other such matter.

REVOCABILITY OF PROXIES

     The grant of a proxy on the enclosed Adatom or HealthCore proxy card does
not preclude a stockholder from voting in person. A stockholder of HealthCore
may revoke a proxy at any time prior to its exercise by (i) delivering, prior to
the HealthCore special meeting, to David Mullikin Secretary, HealthCore, 11904
Blue Ridge Boulevard, Grandview, Missouri, 64030, a written notice of revocation
bearing a later date or time than the proxy; (ii) delivering to the Secretary of
HealthCore a duly executed proxy bearing a later date or time than the revoked
proxy; or (iii) attending the HealthCore special meeting and voting in person. A
stockholder of Adatom may revoke a proxy at any time prior to its exercise by
(i) delivering, prior to the Adatom special meeting, to Richard Barton,
President, Adatom, Inc., 920 Hillview Court, Suite 160, Milipitas, CA 95035, a
written notice of revocation bearing a later date or time than the proxy;
(ii) delivering to the President of Adatom a duly executed proxy bearing a later
date or time than the revoked proxy; or

                                       32
<PAGE>
(iii) attending the Adatom special meeting and voting in person. Attendance at
the relevant special meeting will not by itself constitute revocation of a
proxy. Neither Adatom nor HealthCore expects to adjourn the relevant special
meeting for a period of time long enough to require the setting of a new record
date for such meeting. If an adjournment occurs, it will have no effect on the
ability of either Adatom's or HealthCore's stockholders of record as of the
record date to exercise their voting rights or to revoke any previously
delivered proxies unless the relevant meeting is adjourned to a date that, under
applicable law, requires the setting of a new record date.

SOLICITATION OF PROXIES

     Each of Adatom and HealthCore will bear the cost of solicitation of proxies
from its own stockholders, including related filing fees, however, the cost will
be allocated as a post-closing expense. In addition to solicitation by mail, the
directors, officers and employees of each of Adatom and HealthCore and their
respective subsidiaries may solicit proxies from stockholders of such company by
telephone, telegram or in person. Arrangements will also be made with brokerage
houses and other custodians, nominees and fiduciaries for the forwarding of
solicitation material to the beneficial owners of stock held of record by such
persons, and Adatom and HealthCore will reimburse such company's custodians,
nominees and fiduciaries for their reasonable out-of-pocket expenses in
connection therewith.

     STOCKHOLDERS SHOULD NOT SEND STOCK CERTIFICATES WITH THEIR PROXY CARDS.

                              THE MERGER AGREEMENT

GENERAL

     The HealthCore Board and the Adatom Board have each unanimously approved
the merger agreement. The merger agreement contemplates the merger of Adatom
with and into HealthCore, with HealthCore, renamed Adatom.com, Inc., continuing
as the surviving company. This section of the joint proxy statement/prospectus
describes material provisions of the merger agreement. The description of the
merger agreement contained in this joint proxy statement/prospectus does not
purport to be complete and is qualified in its entirety by reference to the
merger agreement, a copy of which is attached as Annex A to this joint proxy
statement/prospectus and is incorporated herein by reference. Capitalized terms
in this section have the meanings assigned to them in the merger agreement or,
if not so assigned in the merger agreement, the meanings assigned to them in
this joint proxy statement/prospectus. All stockholders of HealthCore and Adatom
are urged to read the merger agreement carefully and in its entirety.

CLOSING; EFFECTIVE TIME

     The closing of the merger will take place at the offices of Epstein Becker
& Green, P.C., 250 Park Avenue, New York, New York 10177 at 9:00 a.m. on the
first business day after the day on which the last condition to the merger is
satisfied or waived or at such other place and time and/or on such other date as
Adatom and HealthCore may agree in writing.

     As soon as practicable following the closing, HealthCore and Adatom will
cause certificate of merger to be filed with, and accepted by, the Secretary of
State of the State of Delaware as provided in Section 252 of the Delaware
General Corporation Law. The merger will become effective at the time the
certificate of merger is filed with the Secretary of State of the State of
Delaware or at a later time agreed by Adatom and HealthCore and established
under the certificate of Merger.

CERTIFICATE OF INCORPORATION OF SURVIVING COMPANY

     The certificate of incorporation of HealthCore as amended will be adopted
as the certificate of incorporation of the surviving company at the closing.

BY-LAWS OF SURVIVING COMPANY

     The by-laws of HealthCore will be adopted as the by-laws of the surviving
company at the closing.

BOARD AND OFFICERS OF SURVIVING COMPANY

     The officers of the surviving company will be the current officers of
Adatom until their successors have been appointed and qualified or until their
earlier death, resignation or removal.

     The directors of the surviving company will be Richard S. Barton and
Sridhar Jagannathan, both of whom are current board members of Adatom and Neal
J. Polan, the current Chairman and Chief Executive Officer of HealthCore. In
addition, Ralph Kennedy Frasier and Sylvia A. Dresner have been appointed by
Adatom pursuant to the merger agreement to be directors to the Board on
Directors of the surviving company.

CONSIDERATION TO BE RECEIVED IN THE MERGER

     At the effective time, Adatom stockholders will receive approximately 2.17
shares of HealthCore common stock in exchange for each share of Adatom common
stock they hold or an aggregate of 10,689,489 shares, subject to adjustment, and
assuming termination of the escrow agreement. After the merger Adatom
stockholders will own approximately 77.5% of the common stock of the combined
company, subject to adjustment. The foregoing calculations give effect to the
issuance of 2,511,620 shares of Adatom common stock before the merger and
assumes exercise of 396,000 options and warrants to purchase HealthCore class A
common stock at an exercise price not greater than $1.25 per share and exercise
of a warrant to purchase 23,315 shares of Adatom common stock. The number of
shares to be received by Adatom stockholders for

                                       34
<PAGE>
each share of Adatom common stock they own will be increased by an additional
 .018 of a share or an aggregate of approximately 195,000 shares for every
$100,000 by which the HealthCore cash assets fail to meet the $2.80 million
threshold at the time of closing. HealthCore's cash assets mean all cash and
prepaid expenses plus $996,981, representing the estimates below:

     o $300,000 in expenses paid by HealthCore in connection with the Merger;

     o $296,981 representing the aggregate exercise price of outstanding options
       and warrants to purchase class A common stock at an exercise price of not
       greater than $1.25 per share;

     o $150,000 payable to Neal J. Polan upon termination of his HealthCore
       employment agreement; and

     o $250,000 previously advanced by HealthCore to Adatom.

      ADATOM STOCK CERTIFICATES SHOULD NOT BE RETURNED WITH THE ENCLOSED PROXY
 CARD. A TRANSMITTAL FORM WILL BE PROVIDED TO HOLDERS FOLLOWING THE EFFECTIVE
 TIME.

TERMINATION

     The merger agreement may be terminated by mutual written consent, or by
either HealthCore or Adatom:

     o if there has been a material breach of any representation, warranty,
       covenant or agreement by the other party;

     o if the merger is not consummated before the November 30, 1999;

     o if the stockholders of HealthCore do not vote to approve the merger;

     o if the Board of Directors of HealthCore recommends an alternative
       transaction to the stockholders of HealthCore; or

     o if a court of competent jurisdiction or other governmental entity issues
       an order, decree or ruling or taken any other action restraining,
       enjoining the consummation of the merger.

EXPENSES

     The out-of-pocket expenses incurred by each party in connection with the
merger shall be paid by, the surviving company following the closing; however,
the aggregate sum of expenses paid by HealthCore prior to the closing are deemed
to be included in the closing cash amount. In the event the merger is not
consummated other than by reason of a termination pursuant to Section 9.1(b) of
the merger agreement, relating to breach of contract, each party shall bear that
portion of the expenses incurred by it in connection with the merger.

     In the event the merger is not consummated by reason of a termination by
either party pursuant to Section 9.1(b) of the merger agreement, relating to
breach of contract, the breaching party shall reimburse the other party for all
transaction expenses, including, without limitation, all of its reasonable
legal, accounting and investment banking fees and expenses relating to the
merger (other than fees, if any, payable to the brokers). In addition, the
non-breaching party will retain all rights and remedies available to it, whether
at law or in equity.

AMENDMENT, EXTENSION AND WAIVER

     Subject to the provisions of the applicable law, the merger agreement may
be modified or amended by the parties at any time prior to the effective time,
by written agreement executed and delivered by duly authorized officers of the
respective parties.

     The conditions to each of the parties' obligations to consummate the merger
may be waived by such party in whole or in part to the extent permitted by
applicable law.

DISSENTERS' RIGHTS

     Under California law, Adatom stockholders who do not vote in favor of the
merger would normally have the right to demand that Adatom purchase their shares
at fair market value. The Adatom stockholders, however, have agreed to vote
their shares in favor of the merger. Therefore, Adatom stockholders will not
have dissenters' rights.

     Under Delaware law, HealthCore stockholders are not entitled to dissenters'
rights because the stock is designated as a national market system security on
an interdealer quotation system by the NASD.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                     CONDITION AND RESULTS OF OPERATIONS OF
                       HEALTHCORE MEDICAL SOLUTIONS INC.

RECENT DEVELOPMENTS

     On July 1, 1999, HealthCore Medical Solutions, Inc., a Delaware
corporation, and Adatom, Inc., a privately held California corporation, entered
into an Agreement and Plan of Merger under which Adatom will be merged with and
into HealthCore with HealthCore being the surviving corporation under the name
Adatom.com, Inc. All existing Class A common stock and warrants of HealthCore
will remain outstanding. The Class B common stock of HealthCore will be
eliminated and the Class A common stock of HealthCore will be retitled as common
stock. Adatom stockholders will receive common stock of the surviving
corporation representing approximately 77.5% of the surviving corporation
subject to adjustment in certain circumstances. Consummation of the merger is
subject to a number of conditions including, without limitation, approval of the
merger by the stockholders of HealthCore and Adatom, and sale or liquidation of
the healthcare discount benefits business operated by HealthCore.

     To satisfy the condition to consummation of the merger that HealthCore
liquidate or sell its discount healthcare business, on July 28, 1999 HealthCore
sold certain of its assets related to its discount healthcare business to
Randolph & Associates, Inc., a Texas corporation and discontinued the operation
of its healthcare discount benefits business. The assets sold included
membership contracts, network access agreements, broker contracts, a computer
hardware lease, certain other miscellaneous contracts, furniture and fixtures,
software and trade names. Randolph agreed to assume performance of HealthCore's
obligations under the assigned contracts as of August 1, 1999. The purchase
price for the purchase of the assets was $4,090.64 in cash, the assumption of a
computer hardware lease for $45,909.36 and the assumption of HealthCore's
obligations under the other assigned contracts arising on or after August 1,
1999 together with all refund obligations due members requested on or after
August 1, 1999 (regardless of the date(s) to which such refunds relate).

     While HealthCore expects to complete the merger in the next several months,
it cannot assure that it will be completed in a timely manner or at all. In the
event the merger is not consummated, HealthCore intends to seek other merger
candidates.

GENERAL

     THE FOLLOWING DISCUSSION RELATES TO THE BUSINESS THAT HEALTHCORE HAS
OPERATED SINCE 1995. AS A CONDITION OF THE MERGER, IN JULY 1999 HEALTHCORE SOLD
THIS BUSINESS. APPROVAL OF THE MERGER AGREEMENT CONSTITUTES RATIFICATION OF THE
SALE OF THIS BUSINESS.

     HealthCore developed, marketed and administered a benefit services program
designed to enable members to obtain discounts on purchases of medical and
consumer products and services through networks of providers with which
HealthCore has executed provider agreements. HealthCore offered three products:
The HealthCare Solutions card, offering discounts for ancillary medical
services; the Medical Solutions Card, providing discounts on major medical
expenses: and the Saving Solutions Card, offering discounts on ancillary medical
and consumer purchases.

     HealthCore's revenues were derived from the receipt of annual or monthly
enrollment fees paid by or on behalf of Members for the right to obtain
discounts from providers in the Networks. HealthCore received a significant
portion of its revenue in the form of monthly bank drafts and monthly payroll
deductions made by employers on behalf of their employees. Accordingly, all
monthly payment sales and their corresponding expenses, including sales
commissions and provider fees, are recognized in the monthly periods for which
they are billed. Since the initial cost of delivering the cards to the customers
is incurred and expensed in the first month, the gross profit associated with
each new individual card issued was lower in the month of issuance than in the
remaining eleven months prior to the card's expiration date. In addition, since
all renewal cards were subject to the same costs of issuance, this twelve-month
pattern of lower gross profits in the first month continued for renewal periods.

                                       40
<PAGE>
     In those instances when a sale of HealthCore's discount cards is collected
as a single annual fee, HealthCore recognized all of its single payment sales in
the period in which the card is delivered, since all of the expenses resulting
from the purchase of an annual card, including the costs of issuance, sales
commission, provider fees, and an provision for cancellations from potential
guarantee-related refunds, are incurred by HealthCore at the time of sale.
HealthCore incurred only nominal additional direct costs associated with each
cardholder in the following eleven months due to the fact that under all of its
provider network contracts, each provider was obligated to continue to provide
discounts to all cardholders until the annual card expires, even if the provider
network contract has been terminated. HealthCore also offered a money-back
guarantee to Members who, within ninety days or after twelve months (depending
on the product), are not satisfied with the discount card and HealthCore has
established reserves therefor.

     The following discussion and analysis should be read in conjunction with
the financial statements and notes thereto appearing elsewhere in this joint
prospectus/proxy statement.

RESULTS OF OPERATIONS

     NINE MONTHS ENDED JUNE 30, 1999 COMPARED TO THE NINE MONTHS ENDED JUNE 30,
1998. Operating revenues for the nine months ended June 30, 1999 (the "1999 Nine
Months") increased by approximately 111% from approximately $69,000 for the nine
months ended June 30, 1998 (the "1998 Nine Months") to approximately $146,000.
Operating revenue for the 1999 Nine Months does not include approximately
$42,000 in annual membership fees received that were deferred until after the
expiration of the money back guarantee period. In addition, operating income
does include recognition of approximately $20,000 in revenues that were deferred
from Fiscal Year 1998. The deferred revenue is being deferred as a result of an
SEC position that income cannot be recognized until after the expiration of the
guarantee period and income from annual contracts must be recognized ratably
over the life of the membership. The overall increase in revenue was a result of
increased sales and marketing efforts to promote HealthCore's products. Selling,
general and administrative expenses increased by approximately 8% from
approximately $1,504,000 in the 1998 Nine Months to approximately $1,628,000 in
the 1999 Nine Months. The increase was due primarily to management level
staffing increases in the sales, marketing and customer service departments and
increased program development costs. Interest expense decreased by approximately
82% from approximately $66,000 for the 1998 Nine Months to approximately $12,000
for the 1999 Nine Months due to the completion of the bridge financing in the
1998 Nine Months and the repayment of the notes issues in the bridge financing
in October 1997. Interest income decreased approximately 44% from approximately
$197,000 for the 1998 Nine Months to approximately $111,000 for the 1999 Nine
Months due to decreased investments effected by corporate needs. Other expense
(in addition to the entries made in the 3rd quarter, see above), also included
additional settlement costs related to proprietary software purchase from a
former employee . Net Loss increased 55% from approximately $1,349,000 for the
1998 Nine Months to approximately $2,091,000 for the 1999 Nine Months as a
result of the foregoing factors.

     FISCAL YEARS ENDED SEPTEMBER 30, 1997 AND 1998.  Revenues of approximately
$84,000 were generated during the fiscal year ended September 30, 1998 compared
to no revenues during the fiscal year ended September 30, 1997. This increase
resulted primarily from the commencement of HealthCore's sales and marketing of
its HealthCare Solution Card following the IPO.

     Selling, general and administrative expenses decreased by approximately
12.4% from approximately $2,489,000 in Fiscal 1997 to approximately $2,180,000
in Fiscal 1998 primarily as a result of non-recurring, non-cash charges of
approximately $789,000 relating to the fair market value adjustments of certain
warrants and shares of capital stock issued to two stockholders of HealthCore in
Fiscal 1997. This decrease was partially offset by (i) an increase in
compensation paid as a result of an increase in the number of employees at
HealthCore following the IPO (ii) an increase in sales and marketing expenses to
support growth in provider Networks and customer and sales support and (iii) an
increase in rent expense due to the installation of HealthCore's telephone
system.

     Interest expense decreased by approximately 91% from approximately $778,000
in Fiscal 1997 to approximately $71,000 in Fiscal 1998. This decrease was due to
the repayment of certain notes issued in a bridge financing completed in
February and March 1997 and amortization of approximately $610,000 being

                                       41
<PAGE>
recognized in Fiscal 1997. Interest income increased by approximately 912% from
approximately $25,000 in Fiscal 1997 to approximately $253,000 in Fiscal 1998
primarily as a result of the investment of the net proceeds of HealthCore's IPO.

     Net loss decreased by approximately 39% from approximately $3,242,000 in
Fiscal 1997 to approximately $1,987,000 in Fiscal 1998 as a result of the
foregoing factors.

LIQUIDITY AND CAPITAL RESOURCES

     HealthCore utilizes capital resources primarily for general corporate
purposes and to support anticipated growth. As of June 30, 1999, HealthCore had
working capital of approximately $2,444,000 including cash and cash equivalents
of approximately $2,330,000.

     Net cash used in operating activities was approximately $1,437,000 for the
1999 Nine Months compared to approximately $1,756,000 for the 1998 Nine Months.
Net cash used in investing activities was approximately $227,000 for 1999 Nine
Months compared to approximately $82,000 for the 1998 Nine Months. Net cash used
in investing activities includes a Notes Receivable to Adatom that was executed
on April 28th and is payable upon demand 90 days after the termination of the
merger agreement should that agreement be terminated.

     Net cash provided by financing activities for the Fiscal 1998 was
approximately $6,376,000. HealthCore realized net proceeds of approximately
$8,748,000 in connection with its IPO which was completed in November 1997 in
which it sold to the public 2,024,000 units at $5.00 per unit (which consisted
of one share of class A common stock and one redeemable class A warrant to
purchase one share of class A common stock at an exercise price of $6.50 at any
time until October 2002), of which approximately $2,300,000 was utilized to
repay the Bridge Notes issued in the Bridge Financing which was completed in
February and March 1997, approximately $104,000 was utilized in repayment of
other notes payables, and approximately $54,000 was used in principal payments
under capital lease obligations.

YEAR 2000 COMPLIANCE

     Certain aspects of HealthCore's business, including its customer service
capabilities, HealthCore's ability to timely pay brokers their commissions and
pay network providers their fees, are dependent upon the ability to store,
retrieve, process and manage data and to maintain and upgrade the data
processing system HealthCore currently relies on. Although HealthCore believed
that it had established appropriate safeguard mechanisms, interruption of data
processing capabilities for any extended period of time, loss of stored data,
programming errors or other computer problems could have affected its ability to
attract and retain brokers and networks, which in turn may have negatively
affected its business.

     HealthCore commenced review of its computer systems to identify the systems
that could be affected by the "Year 2000" issue and was developing an
implementation plan to resolve the issue. The Year 2000 issue is the result of
computer programs being written using two digits rather than four to define the
applicable year. Any of HealthCore's programs that have time-sensitive software
may recognize a date using "00" as the year 1900 rather than the year 2000. The
Year 2000 issue could arise at any point in HealthCore's processing,
distribution and financial chains and could have resulted in a major system
failure or miscalculations, affected its ability to pay commissions and fees to
its brokers and networks, as well as its ability to review network providers in
a timely manner and on the whole disrupt its business operations.

     HealthCore was utilizing internal personnel, contract programmers and
vendors to review its information and operational systems, including the DBIM
System, for purposes of identifying Year 2000 non-compliance problems.
HealthCore had identified two specific areas of risks relating to the Year 2000
problem: internal business systems and software and external noncompliance by
third parties including suppliers of participating providers data, suppliers
requiring information about our eligibility, financial vendors and HealthCore's
members.

     Internal Business Systems and Software.  HealthCore's systems, including
the DBIM System, were developed utilizing program source code and off-the-shelf
software that was Year 2000 compliant. The total estimated cost of the hardware,
software and installation cost of HealthCore's system, including the DBIM

                                       42
<PAGE>
System, was approximately $600,000, a portion of which was allocated to Year
2000 compliance. All available upgrades for off-the-shelf products (which
include Year 2000 compliance) had been loaded and were in active use.
HealthCore's telephone system vendors indicated Year 2000 compliance including
services relating to long distance, local, 1-800, telephone switch and audix.

     External Non-Compliance by Third Parties--Suppliers of Participating
Providers Data.  A survey of all suppliers of participating providers data was
begun and was 90% completed. Of the suppliers who had responded to our survey,
all have indicated that they are Year 2000 compliant.

     External Non-Compliance by Third Parties--Suppliers Requiring Information
About Eligibility.  A survey of all suppliers requiring information about
HealthCore's eligibility was conducted with an 85% response rate. Two pharmacy
benefits management suppliers with whom HealthCore had contracts have indicated
that they are Year 2000 compliant. To the extent that HealthCore determined that
any of its suppliers' responses to the Year 2000 issue was unsatisfactory, it
considered alternate sources of suppliers.

     External Non-Compliance by Third Parties--Financial Vendors.  Financial
vendors such as HealthCore's merchant bank and credit card processor have not
yet been surveyed. HealthCore expected that such surveys would be conducted no
later than the first quarter of 1999. To the extent that HealthCore's financial
vendors were not Year 2000 compliant, HealthCore would have considered alternate
sources of financial vendors who were Year 2000 compliant.

     External Noncompliance by Third Parties--Sponsors.  HealthCore did not
currently have any formal information about the status of its sponsors and the
Year 2000 issue. HealthCore received indications that most of its sponsors were
in the process of becoming Year 2000 compliant.

     Through September 30, 1998, HealthCore incurred costs of approximately
$600,000 to update HealthCore's systems, a portion of which was allocated to
Year 2000 compliance. In addition, HealthCore incurred additional costs in
connection with HealthCore's review of internal and external systems compliance,
none of which was material.

     The impact of the Year 2000 problem on HealthCore's business as presented
was based on the management's best estimates at the time. Such estimates were
based on the results of HealthCore's internal review of its information and
operational systems and formal surveys received from third parties to date. The
estimates were made using assumptions of future events including the continued
availability of certain resources, Year 2000 modification plans, implementation
success by key third-parties, and other factors.

     Release of Escrow Shares.  In connection with the IPO, the pre-IPO
stockholders of HealthCore placed, on a pro rata basis, a portion of their
shares into escrow pending HealthCore's attainment of certain earnings
thresholds or per share stock price thresholds. The Commission has taken the
position with respect to the release of securities from escrow that in the event
the Escrow Shares are released from escrow to directors, officers, employees or
consultants of HealthCore, the release will be treated, for financial reporting
purposes, as compensation expense to HealthCore. Accordingly, in the event of
the release of the Escrow Shares, HealthCore will recognize during the period in
which the earnings or market price targets are met or become probable of being
met, a substantial non-cash charge which would substantially increase
HealthCore's loss or reduce or eliminate earnings, if any, at such time. The
amount of compensation expense recognized by HealthCore will not affect
HealthCore's total stockholders' equity. In addition, a portion of the warrants
issued to Neal J. Polan will become exercisable only upon the attainment by
HealthCore of certain earnings or market price thresholds. In the event that
such warrants become exercisable, HealthCore will recognize during the period in
which the earnings thresholds are probable of being met or such stock levels
achieved, an additional non-cash charge to earnings equal to the fair market
value of the portion of the warrants subject to such earnings or market price
thresholds, which could have the effect of significantly increasing HealthCore's
loss or reducing or eliminating earnings, if any, at such time.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                                OF ADATOM, INC.

RESULTS OF OPERATIONS

Six Months Ended June 30, 1998 and 1999.

     Revenues of approximately $261,000 were generated during the six months
ended June 30, 1999, compared to revenues of approximately $207,000 during the
six months ended June 30, 1998. The quarter ended June 30, 1999 is the third
quarter in which Adatom's website was established and functioning. Revenues in
the corresponding 1998 period were generated predominantly by inbound telephonic
contact by customers.

     Research and development expenses increased from approximately $188,000 in
the period ended June 30, 1998 to approximately $279,000 in the period ended
June 30, 1999, principally due to the ongoing development efforts related to
Adatom's website and to the systems and software development effort to automate
its order submission and status tracking capabilities with the various
manufacturers. These costs were predominantly in the nature of fees paid to
outside software developers and website designers.

     Selling, general, and administrative expenses increased from approximately
$402,000 in the six month period ended June 30, 1998 to approximately $628,000
in the six month period ended June 30, 1999, principally due to the increase in
advertising expenses (which during the six-month period ended June 30, 1999
consisted almost exclusively of fees paid to organizations with internet sites
which provided Adatom with space on the site or a link to Adatom's website). In
addition salaries and legal fees increased by approximately $102,000 from
$175,000 for the six months ended June 30, 1998 to $277,000 for the six months
ended June 30, 1999.

     Net loss increased approximately 165% from approximately $331,000 in the
six months ended June 30, 1998, to approximately $878,000 in the six months
ended June 30, 1999, primarily due to the absence of $250,000 nonrecurring other
income in 1999 as there had been in 1998 and expenses increasing faster than
revenue..

Fiscal Years Ended December 31, 1997 and 1998.

     In 1997, approximately 50% of Adatom's total revenue of approximately
$244,000 was derived from the sale of franchise rights. Adatom's business plan
at that time identified franchisees as principal points of contact with
prospective customers, and in pursuing that strategy, Adatom sold eight
franchises in 1997. Substantially all of the purchase price for the franchises
was financed by Adatom under 60-month, 9%, unsecured notes. The balance of
Adatom's revenue in 1997 was derived from "direct sales" to customers who
contacted Adatom via its toll-free telephone number. Adatom had established
relationships with several manufacturers of consumer products, and fulfilled
customer orders by placing its own order with the manufacturer and arranging for
direct shipment of the product to the customer. Customers paid for their orders
via credit card and the direct shipment of goods directly to the customer from
the manufacturer for the vast majority of sales eliminated the need for Adatom
to carry significant inventory.

     Although total revenue in 1998 increased by nearly 19% over 1997, the mix
of revenue shifted almost exclusively to direct sales to customers, since the
franchise concept was terminated by Adatom. Adatom's business plan evolved
through the year to one that was based on retailing via the Internet.
Internet-generated sales commenced in the fourth quarter of 1998 and are
estimated to account for less than $40,000 of Adatom's annual revenue for 1998.
Direct sales to customers from both inbound telephonic inquiries and from
Internet-generated contacts accounted for approximately $285,000 of the $290,000
in total revenue for 1998.

     The research and development effort undertaken by Adatom in 1997 was
principally directed at establishing the computer-based order entry/tracking
function and its interface to the financial reporting function. Costs were also
incurred initially to support the franchisee network, by enabling dial-up order
download from the remote franchisee locations. This development effort included
both the customization of "off-the-shelf" software and the creation of new
software for the desired functions and interface capabilities.

                                       45
<PAGE>
     With the shift in the strategic direction of Adatom undertaken in 1998,
research and development expenses increased by approximately 37% over 1997, due
principally to the costs incurred in the development of Adatom's Internet site.
These costs were predominantly in the nature of fees paid to outside software
developers and web-site designers. Additionally, having focused its efforts in
1997 at the customer order end of the shopping process, Adatom began to address
the need to automate its order submission and status tracking capabilities with
the various manufacturers. This effort continues in 1999. By the fourth quarter
of 1998, the website development effort had been completed to the point that
some revenues were being generated from it. Maintenance of the website, however,
is a constant operational need and is an ongoing source of significant expense
by Adatom.

     Selling, general and administrative expenses increased approximately 103%
in 1998 to approximately $915,000 from $451,000. Principal reasons for this
increase include the increase in salary expense of approximately $110,000 due to
the addition of several personnel throughout the year, and the increase in
advertising expense of approximately $140,000 mainly due to development,
production, and mailing costs of the brochure which was mass-mailed to several
thousand prospective customers.

     In 1998, Adatom earned $250,000 from a technology-sharing license agreement
under which Adatom licensed the use of its technology to one of its vendors.
Additionally, in 1998 Adatom terminated the franchise portion of its business
and offered to cancel the remaining balance of notes receivable due from
franchisee. As a result of this termination, Adatom took a charge of
approximately $79,000 for the write-off of the notes.

     Interest expense increased approximately 165% from approximately $20,000 in
1997 to $53,000 in 1998 primarily as a result of increased loans from the
principal shareholder.

     Net loss increased approximately 77% from approximately $653,000 in 1997 to
approximately $1,156,000 in 1998 as a result of spending for research and
development expenses and for selling, general and administrative expenses
increasing at significantly greater amounts than did revenues.

LIQUIDITY AND CAPITAL RESOURCES

     Adatom utilizes capital primarily for research and development, for general
corporate purposes and to support anticipated growth. At December 31, 1998 and
June 30, 1999, Adatom had negative working capital of approximately $239,000 and
$822,000 respectively. Net cash used in operating activities for 1998 was
approximately $831,000. Adatom estimates the ongoing maintenance, operations and
development costs for its website will be approximately $2.5 million in the
fiscal year 2000 and anticipates that these costs will increase in the future.
In addition, Adatom estimates that planned enhancements to its website and
back-end capabilities required over the next 16 months will cost approximately
$1.4 million. Although no commitments exist requiring the expenditure of these
amounts, Adatom expects to pursue these efforts through 1999 and 2000.

     To date, Adatom has funded its cash needs almost exclusively by loans from
Richard Barton, its majority shareholder. These loans have an outstanding
balance of approximately $1,800,000. In connection with the merger, it is
anticipated that these loans will be converted to equity. Mr. Barton does not
intend to make further loans to Adatom.

     In April 1999, after execution of the letter of intent with HealthCore
relating to the merger, HealthCore loaned Adatom $250,000. This loan was used
for working capital purposes and will be discharged as part of the merger. In
early July, Jesup & Lamont Acquisition Corporation loaned Adatom $500,000. The
note signed by Adatom for this loan provided that it will convert immediately
prior to the merger into the number of shares of Adatom common stock equal to
4.74% of the outstanding common stock of Adatom. This loan was used for working
capital purposes. In connection with this loan, Jesup & Lamont Securities
Corporation received a warrant from Adatom for approximately 23,315 shares of
Adatom common stock at an exercise price of $2.14 per share. In late August and
early September, Richard Barton loaned Adatom an aggregate principal amount of
$250,000, which will be repaid within 60 days. The interest rate on these loans
is 6%. The proceeds of both the $500,000 and $250,000 loans have been exhausted
by Adatom and Jesup is currently attempting to raise an additional $500,000 of
working capital for Adatom. It is anticipated that this additional working
capital will be combined with the prior loan into a $1,000,000 convertible note
that would convert immediately prior to the merger into the number of shares of
Adatom equal to 9.48% of the outstanding stock of Adatom (and which, at the
assumed exchange ratio in the merger prior to the adjustment, will equal
approximately 7.35% of the post-merger stock of HealthCore). It is anticipated
that these funds will be exhausted by the closing of the merger).

     After the merger, Adatom will have approximately $2 million of cash and
cash equivalents currently held by HealthCore and will use this money for
general corporate purposes. Adatom also intends to raise at least $5.5 million
in new equity during the fourth quarter of 1999, which will dilute all
stockholders. However, no assurance can be given that Adatom will be successful
in raising this capital and, if it is not, the business of Adatom will be
materially and adversely affected.

     Adatom has been unable to obtain bank financing to fund its business and is
therefore dependent on internal cash flow and the ability to raise equity. Under
its current business plan, the cash and cash equivalents of HealthCore available
to Adatom after the merger will provide funds for Adatom for approximately two
months and the cash and cash equivalents combined with the proposed $5 million
equity infusion will provide funds for Adatom for approximately six months.
Adatom estimates that its total cash requirements between the date hereof and
December 31, 2000 will be approximately $16 million.

YEAR 2000 COMPLIANCE

     The Year 2000 issue is the result of computer programs using only the last
two digits to indicate the year. If uncorrected, such computer programs will not
be able to interpret dates correctly beyond the year 1999 and, in some cases
prior to that time (as some computer experts believe), which could cause
computer system failures or other computer errors disrupting business
operations. Recognizing the potentially severe consequences of the failure to be
Year 2000-compliant, Adatom has begun to review its hardware and software
systems in order to identify and remedy the Year 2000 issues.

     The scope of Adatom's Year 2000 readiness program includes the review and
evaluation of (i) Adatom's technology ("IT") such as hardware and software
utilized in the operation of the company's business and (ii) Adatom's non-IT
systems or embedded technology such as microcontrollers contained in various
equipment and facilities. If needed modifications and conversions are not made
on a timely basis, the Year 2000 issue could have a material adverse effect on
Adatom's operations.

     Adatom is currently conducting a review of its hardware and software
systems in an effort to ensure Year 2000 compliance. Adatom's hardware systems
and some software systems were acquired from reliable third party vendors and
Adatom will attempt to verify that these products are certified to be Year
2000-compliant, and will also attempt to verify that its internally developed
software is Year 2000-compliant. Remediation of these systems is expected to be
completed by November 1999 except for Adatom's general corporate systems,
consisting principally of its accounting system, which are already Year
2000-compliant.

     Adatom has not contacted key suppliers, vendors and customers to assess
their Year 2000 readiness. If third parties do not convert their systems in a
timely manner and in a way compatible with Adatom's systems, the arrival of the
Year 2000 could have an adverse effect on the company's operations.

     Adatom has not yet developed a contingency plan specifying what the company
will do if it or important third parties are not Year 2000-compliant by the
required dates, although it expects to begin development of such a plan shortly.
Adatom anticipates that any contingency plan developed will be based almost
exclusively on manual back-up systems, procedures and practices. The contingency
plan is estimated to be completed by November 1999.

     Through July 1999, Adatom estimates that incremental costs of approximately
$20,000 have been incurred and expensed related to Year 2000 issues. Since many
systems are being modified to provide significant enhanced capabilities, the
Year 2000 expenses have not been and are not planned to be specifically tracked.
The current estimated cost to complete remediation is expected to be less than
$50,000. Adatom expects that a portion of these costs will be capitalized, as
they are principally related to adding functionality. Other costs will continue
to be expensed as incurred.

     Adatom's current estimates of the amount of time and costs necessary to
remediate and test its computer systems are based on the facts and circumstances
existing at this time. The estimates were made using assumptions of future
events including the continued availability of existing resources, Year 2000
modification plans, implementation success by third-parties, and other factors.
New developments may occur that could affect Adatom's estimates of the amount of
time and costs necessary to modify and test its IT and non-IT systems for Year
2000 compliance. These developments include, but are not limited to: (i) the
availability and cost of personnel trained in this area, (ii) the ability to
locate and correct all relevant computer codes and equipment and (iii) the
planning and Year 2000 compliance success that key suppliers, vendors and
customers attain.

               UNAUDITED PRO FORMA CONDENSED FINANCIAL STATEMENTS

     The following unaudited pro forma condensed financial statements give
effect to the proposed merger of HealthCore and Adatom pursuant to the merger
agreement.

     The unaudited pro forma condensed financial statements are based on the
respective historical financial statements and notes thereto of HealthCore and
Adatom. The unaudited pro forma condensed combined balance sheet assumes that
the merger took place on June 30, 1999 and combines HealthCore's and Adatom's
June 30, 1999 balance sheets. The unaudited pro forma condensed statements of
operations assume that the merger took place as of the beginning of the periods
presented and combines HealthCore's statements of operations for the six months
ended March 31, 1999 and the fiscal year ended September 30, 1998 with Adatom's
statements of operations for the six months ended June 30, 1999 and the calendar
year ended December 31, 1998, respectively.

     The merger will be treated as a recapitalization for accounting purposes.
In a recapitalization of this type, HealthCore's retained deficit is permanently
eliminated, its permanent capital is reduced by the amount of its former
retained deficit and its assets and liabilities are revalued at fair market
value. Although HealthCore will be the surviving corporate entity, Adatom's
current stockholders will own approximately 77.5% of the merged entity. The
unaudited pro forma condensed combined financial statements have been prepared
on the basis of assumptions described in the notes thereto. In the opinion of
HealthCore and Adatom, all adjustments necessary to present fairly the unaudited
pro forma condensed combined financial statements have been made based on the
proposed terms and structure of the merger.

     The pro forma adjustments have been made solely for purposes of developing
such pro forma information for illustrative purposes necessary to comply with
the disclosure requirements and is not necessarily indicative of the operating
results or financial position that would have occurred if the merger had been
consummated on the dates indicated, nor is it necessarily indicative of future
operating results or financial position.

     These unaudited pro forma condensed financial statements should be read in
conjunction with the historical financial statements and the related notes
thereto of HealthCore and Adatom which are included herein and Management's
Discussion and Analysis of Financial Condition and Results of Operations.

                             INFORMATION CONCERNING
                       HEALTHCORE MEDICAL SOLUTIONS INC.

GENERAL

     THE FOLLOWING DISCUSSION RELATES TO THE BUSINESS THAT HEALTHCORE HAS BEEN
OPERATING SINCE 1995. AS A CONDITION OF THE MERGER, HEALTHCORE SOLD THIS
BUSINESS AND, AT THE TIME OF THE MERGER, WILL COMMENCE OPERATIONS OF ADATOM'S
INTERNET RETAILING BUSINESS. APPROVAL OF THE MERGER AGREEMENT CONSTITUTES
RATIFICATION OF THE SALE OF THIS BUSINESS.

     HealthCore marketed and administered a health care benefit services program
which was designed to enable participants to obtain discounts on purchases of
health care products and services through certain networks of health care
providers. For an annual fee of approximately $55 to $100, individuals could
join HealthCore's card membership program and use their HealthCare Solutions
Card to receive discounts of up to 5% to 60% off the retail price of health care
services and products including retail and mail-order eye care, pharmaceutical
and durable medical equipment, retail dental, hearing, physical and occupational
therapy and chiropractic, and retail mail-order vitamins and supplements. In
addition to the HealthCare Solutions Card, HealthCore began marketing two new
products: the Savings Solutions Card, which was customized for an organization
to offer discounted ancillary health care services as well as non-medical
consumer products to certain subscribers in the New York metropolitan area, and
the Medical Solutions Card, which provided nationwide discounts to enrollees for
hospital and physician services. As of December 29, 1998, HealthCore had
contracts with approximately 40 different networks which consisted of
approximately 450,000 participating providers.

     HealthCore's target market included uninsured individuals who, whether
because of their medical history, age or occupation, either did not have
insurance or had limited insurance coverage but who seek to access health care
products and services at discounted costs. Acceptance into HealthCore's
membership programs was unrestricted, and HealthCore's membership card products
were used by any member of the cardholder's household. HealthCore primarily used
brokers, insurance agents and consumer marketing organizations to sell its
maintenance organizations and other organizations or sponsors who purchase
HealthCore's products for their employees or members.

     HealthCore was established in October 1995 as MegaVision L.C., a Missouri
limited liability company. In February 1997, MegaVision merged into HealthCore
Medical Solutions, Inc. Except as otherwise required by the context, all
references to HealthCore and its operations include MegaVision and its
operations. HealthCore's executive offices were located at 11904 Blue Ridge
Boulevard, Grandview, Missouri 64030 and its telephone number was (816)
763-4900.

PRODUCTS

     The HealthCare Solutions Card. The HealthCare Solutions Card enabled
members to obtain discounts of approximately 5% to 50% on purchases of ancillary
health care products and services through certain networks of providers.

     For an annual fee of approximately $55 to $100, members had access to
participating providers, and automatically received a discount at the
point-of-purchase upon presentation of the HealthCare Solutions Card. HealthCore
entered into non-exclusive agreements with national networks of eye care service
providers, dental service providers, pharmaceutical providers, a hearing service
provider, a national network of chiropractic service providers, a national
network of providers of durable medical equipment and providers of mail-order
vitamins and supplements, pharmacy and eye care to participate in HealthCore's
networks. The networks with which HealthCore has contracted were generally
created to provide individuals with access to health care products and services
at reduced costs and to provide such individuals with broader geographical
access to such providers. Pursuant to agreements entered into between the
networks and the providers, the providers agreed to provide health care services
to members of the networks at reduced costs and, in exchange, providers are
given access to additional patients and additional sources of revenue.

                                       55

     HealthCore's agreements with its networks were generally for a term of one
to three years and provided for termination by either party in the event of a
default or, at any time after a stipulated period of time following the
execution of the agreement (generally ranging from six months to three years)
upon 60 to 90 days prior written notice. The agreements also provided that upon
termination of an agreement for any reason, HealthCore and the Providers
participating in such networks would continue to provide services to members,
for the term of their enrollment, if they purchased the HealthCare Solutions
Card for access to such Provider's network prior to such termination. In
addition, under certain agreements, HealthCore paid a stipulated access fee per
member per year to the representative network in exchange for access by members
to such networks. In the case of HealthCore's agreement with one of its
pharmaceutical networks, HealthCore also received a stipulated commission from
such network for each prescription ordered by a member.

     The Savings Solutions Card. HealthCore launched a Savings Solutions Card,
offering discounts on medical services and products, pharmacy products, vitamins
and supplements, veterinary services and pet products, long-term care and
assisted living, home health care, and certain consumer purchases including
jewelry, furniture and travel. This product was developed specifically for an
organization in the New York and New Jersey area. As of December 28, 1998, the
network was comprised of providers in the New York and New Jersey area and
HealthCore anticipated marketing the Savings Solution Card in certain regions
throughout the United States.

ADVANTAGES OF THE SOLUTIONS CARD

     Advantages to Members. In addition to providing access to health care
products and services on a discounted fee-for-service basis at the point of
purchase, HealthCore believed the HealthCare Solutions Card, the Savings
Solution Card and the Medical Solutions Card were attractive to members because
of their flexibility and ease of use. HealthCore's target market included
uninsured individuals who, whether because of their medical history, age or
occupation, either did not have insurance or had limited insurance coverage but
who sought to access health care products and services at discounted costs.
Acceptance into our membership program was unrestricted, and our Savings Cards
was used by any member of the cardholder's household. The Savings Cards covered
each person in the member's immediate household and could be used as often as
each participant wished. In addition, unlike many traditional indemnity or
managed care programs, members had no paperwork or claims to prepare, no waiting
periods, and no prior authorizations are required. Moreover, in certain cases,
membership in HealthCore's programs entitled members to benefits that would
otherwise be unavailable or difficult to obtain. In addition, even where a
member already had insurance for a particular product or service, the Savings
Cards entitled members to various discounted products and services that would
typically be excluded from traditional health care insurance, including certain
pharmaceuticals, vitamins, growth hormones, oral contraceptives, smoking
deterrents and fertility drugs, and certain elective procedures and services.

     Advantages to Providers and Networks. HealthCore believed that health care
providers were attracted to HealthCore's programs because it enabled them to
obtain additional patients who were members while allowing providers to retain
their existing practices. Although members generally paid fees and charges less
than those of non-members, the incremental business from members could be an
important source of revenue to the providers, with little or no increase in
their overhead costs. However, there was no assurance that providers would
continue to participate in the networks even if their participation resulted in
such an increase in revenues since the member portion of their business may be
relatively less profitable. In addition, HealthCore believed that its programs
were attractive to provider networks because it could increase the likelihood
that providers would affiliate with provider networks in order to have access to
members, and accordingly, provider networks may have realized increased revenues
from such affiliations. Further, HealthCore believed that its programs were
attractive to provider networks for the following reasons: (i) providers
received cash at the time services are rendered; (ii) providers were not
required to file claims; and (iii) providers were not subject to a waiting
period for payment from a third party payor.

     Advantages to Sponsors. HealthCore believed that the Savings Cards assisted
Sponsors in their efforts to attract and retain employees by enabling them to
offer a more complete health care benefits package. Similarly, as competition
between HMOs for participants continued to intensify, HealthCore believed that
the Savings Cards enabled HMOs to offer a more complete, and therefore more
attractive, array of potential health care benefits. In addition, due to the low
cost of the Savings Cards, sponsors could choose to offer it to part-time
employees, who often were not eligible for health care benefits offered to
full-time employees. Moreover, because the Savings Cards were discount cards and
not insurance products, Sponsors could offer

                                       58
<PAGE>
discounts to their employees or members without bearing any economic risk over
the annual cost of the cards.

SALES AND MARKETING

     HealthCore relied primarily upon the services of independent sales
representatives, including brokers, agents, consumer marketing organizations and
associations, to market the Savings Cards. These arrangements generally provided
for commissions based upon a percentage of sales of the Savings Cards, which
commissions ranged from 20% to 50% of the aggregate sales price. HealthCore
believed that there are a large number of independent brokers and other agents
nationwide with whom HealthCore could establish relationships. To date,
HealthCore entered into numerous agreements with individuals, including
individuals affiliated with American Family Life Assurance Company, who were
expected to serve as independent brokers. HealthCore intended to continue to
contract with additional independent brokers in the future and believed that
certain of its networks could provide HealthCore with access to additional
independent brokers. In addition, HealthCore maintained an in-house sales force
that consisted of three persons.

     HealthCore marketed the Savings Cards principally to potential Sponsors,
including insurance carriers, third party administrators, corporations, HMOs,
preferred provider organizations, Blue Cross and Blue Shield organizations and
unions, which had, or had access to, a large number of potential members.
HealthCore believed that its use of independent brokers and third party
administrators would not only provide immediate access to specific organizations
with potential members, but would also enable HealthCore to establish
relationships with these individuals and entities who might have been
gatekeepers to even greater numbers of potential members through their extensive
contacts in their respective industries.

     HealthCore anticipated that Sponsors would either fund the Savings Card
program on behalf of their members or employees so that every eligible
individual in the organization becomes a member or they would offer the Savings
Cards to their members or employees as an option where each individual would be
responsible for purchasing the Savings Cards and paying the annual fee (either
directly or through a payroll deduction plan). HealthCore also marketed the
Savings Cards directly to potential members, particularly in cases where a
Sponsor offered the Savings Cards as an unpaid option to its members or
employees.

     HealthCore also marketed the Savings Cards as "affinity" cards to selected
large Sponsors, including large corporations and consumer marketing
organizations. Pursuant to such affinity card arrangements, the Sponsor would be
able to custom design, and place its own name on the Savings Cards. In certain
cases, HealthCore's name may not appear on the cards, although HealthCore would
provide access to its networks, as well as all required fulfillment services.
HealthCore believed that affinity cards would be attractive to certain Sponsors
because they would enable the Sponsor to more closely identify itself with the
benefit provided to the member. Moreover, HealthCore believed that the
preexisting relationship, or affinity, between the Sponsor and its employees or
members would enhance the likelihood that a potential member would purchase the
cards.

THE PROPRIETARY DATABASE INFORMATION MANAGEMENT SYSTEM

     HealthCore believed its proprietary database information management system
(i) facilitated HealthCore's ability to process member applications and access
member and provider data, (ii) enhanced HealthCore's customer service
capabilities and (iii) facilitated HealthCore's ability to process and pay
commissions to brokers and fees to certain networks. The DBIM System contained
information relating to members, such as eligibility in the respective plan,
services and products available to members, the discounts available to the
member for services and products, locations of providers and utilization data
provided to HealthCore on a regular basis by each of the providers in the
networks. HealthCore believed that the DBIM System enabled it to enroll members
electronically, quickly respond to information requests from members, sponsors
and providers, assist members in locating the nearest provider and facilitate
billing and data processing.

     HealthCore developed an internet web site at www.solutionscard.com which
was accessible by existing and potential providers, members and independent
sales representatives. Individuals accessing the web site were able to review
the health care benefit plans offered by HealthCore, a list of providers in the
networks and their locations, and products and services provided by the
providers, the discounts available to members

                                       59
<PAGE>
for services and products and any special promotions. Individuals accessing
HealthCore's internet web site were able to immediately apply for any of
HealthCore's Savings Cards by filling out an application online.

COMPETITION

     HealthCore believed that a critical element of its business was the
competition for a portion of the benefit dollars allocated by various
organizations for employee benefit programs. HealthCore competed for a portion
of those dollars with various other cost-containment marketing organizations,
pharmacy indemnity programs, retail pharmacies, mail-order prescription, and
vitamin and supplement companies, preferred provider organizations, HMOs, health
care membership programs and other health care insurance programs for members
and providers. With respect to its health care services, HealthCore competed for
potential sponsors, members and providers, depending on the geographic area or
market, with various entities that have developed discount membership cards
which provide national coverage, including a number of companies with longer
operating histories and substantially greater financial and other resources than
HealthCore and entities that had developed discount membership cards which
provide only regional coverage. HealthCore also competed with various
organizations which provided services and products in specific areas of health
care such as eye care services, pharmacy indemnity programs, independent and
chain-operated retail pharmacy outlets, retail medical/surgical supply companies
and other mail order prescription and, vitamin and supplement companies, HMOs
and health care membership programs. Most of these competitors had longer
operating histories and had significantly greater financial, marketing and
administrative resources than HealthCore. There was no assurance that HealthCore
would develop products that achieved greater market acceptance than competitive
products or that HealthCore's competitors would not succeed in developing
products that would render HealthCore's products less competitive or obsolete.

     HealthCore believed that the broad range of choices of health care benefit
packages, its customer service capabilities resulting from the DBIM System, its
broad provider base, independent broker market (as opposed to multilevel
marketing) and its competitive pricing differentiated it from its competitors
and enabled it to offer a more comprehensive and cost effective solution to its
customers' needs.

GOVERNMENT REGULATION

     The delivery of health care products and services was subject to extensive
federal, state and local regulation, including but not limited to the
prohibition of business corporations from providing medical care, fraud and
abuse provisions of the Medicare and Medicaid statutes, state laws that prohibit
referral fees and fee splitting and certain regulations applicable to insurance
companies and certain organizations that provide or arrange for health care
services. HealthCore believed that certain registration and licensing laws and
regulations in certain states in which HealthCore operated may have applied to
HealthCore's operations. In addition, statutes and regulations applicable to
other health care organizations with which HealthCore contracted, including
without limitation those relating to fee splitting, referral fees, patient
freedom of choice, provider rights to participate and anti-discrimination, may
have impacted HealthCore and resulted in the delay or denial of any such
organization's participation in HealthCore's networks.

     The utilization fees received by HealthCore in connection with the
Mail-Order Pharmaceutical Plan might be construed to have contravened the
literal provisions of these statutes and regulations in a number of states in
which HealthCore operated. In addition, certain states in which HealthCore
offered the Savings Cards took the position that certain of the discounted
services offered by HealthCore's networks could be interpreted as prepaid
insurance and in some states, HealthCore and its networks modified the services
offered in order to comply with such state laws.

     Although HealthCore did not obtain any rulings from any governmental
authorities or an opinion of counsel with regard to any of these matters,
HealthCore believed that the extent of its compliance with such laws and
regulations as they were currently enforced and applicable to HealthCore was
consistent with current industry practices and would not have a material adverse
effect on its business.

PROPRIETARY RIGHTS

     The DBIM System was a critical component of HealthCore's ability to provide
customer service and process other data. HealthCore relied on trade secrets to
establish and protect its proprietary rights to its DBIM System. However, trade
secrets were difficult to protect and there could be no assurance that others
would not independently develop substantially equivalent proprietary technology
or otherwise gain access to HealthCore's trade secrets or disclose such
technology, or that HealthCore could meaningfully protect its rights to
non-patented trade secrets.

     HealthCore applied for federal registrations of the service marks
"Healthcare Solutions," "The Solutions Card," "Healthcare Savings Guaranteed,"
and "HealthCore Medical Solutions, Inc.," intended to apply for registration of
the service marks "Savings Solutions," "Medical Solutions" and certain other
service marks from the United States Patent and Trademark Office, but there
could be no assurance that such rights would be granted. HealthCore was aware of
several companies who may have been using variations of HealthCore's trade names
or service marks in connection with certain health care activities and at least
one other company who may have been using certain of HealthCore's trade names or
service marks in connection with a business that is competitive with
HealthCore's business.

EMPLOYEES

     HealthCore had 3 full-time employees and 2 part-time employees. None of
HealthCore's employees was represented by a labor union. HealthCore did not
experience any work stoppages and considered its relations with its employees to
be good.

                SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS,
                      DIRECTORS AND OFFICERS OF HEALTHCORE

     The following table sets forth certain information as of September 10,
1999, based on information obtained from the persons named below, with respect
to the beneficial ownership of shares of HealthCore common stock by (i) each
person known by HealthCore to beneficially own more than 5% of the outstanding
shares of HealthCore common stock, (ii) each executive officer and director of
HealthCore, and (iii) all officers and directors of HealthCore as a group.

     Beneficial ownership is defined in accordance with the rules of the SEC and
generally means the power to vote and/or to dispose of the securities regardless
of any economic interest therein. In computing the number and percentage
ownership of shares of common stock beneficially owned by a person, shares of
common stock subject to options or warrants held by that person that are
excisable within 60 days are deemed outstanding. Such shares of common stock,
however, are not deemed outstanding for purposes of computing the percentage
ownership of stockholders other than such person. In calculating beneficial
ownership of HealthCore after the merger, we have assumed that there will be
13,346,228 shares outstanding based on the number of shares of Adatom common
stock to be outstanding immediately prior to the merger, after giving effect
immediately prior to the merger to the issuance of certain shares of Adatom
common stock, including certain new issuances, shares issued upon conversion of
Adatom convertible debentures and upon conversion of $1,800,000 of shareholder
debt and shares issued upon exercise of warrants to purchase Adatom common stock
and the fixed exchange ratio in the merger of approximately 2.17 shares for each
share of Adatom.com, Inc. common stock for each share of Adatom common stock.

                             INFORMATION CONCERNING
                                  ADATOM, INC.

CORPORATE STRUCTURE

     Adatom Inc. was founded in 1996 by a team of seasoned, motivated, and
dedicated executives, who met at and graduated from the Sloan Fellowship Program
of Stanford University Business School. The team has a well-balanced mixture of
managerial, marketing, and technical experience. Richard Barton, President and
Chief Executive Officer, has 24 years of marketing, sales and general management
experience. Dr. Sridhar Jagannathan, Chief Technology Officer and Executive Vice
President, has 15 years of software development, consulting and program
management experience, knowledge of database systems and associated
applications, and an incisive understanding of emerging technologies. Adatom's
management has invested a total of approximately $1.85 million in Adatom.

     After commencing business as a retailer which had no store sites and used a
mobile sales force of franchisees, Adatom shifted its focus to internet
e-commerce. Adatom has built an Internet E-tail System which has the capability
to acquire, market, order, fulfill, ship and install a broad range of goods on
the Internet. This Internet E-tail System is used by Adatom to run its online
business (www.adatom.com) and is intended to be used in the future to launch and
manage other web site e-commerce initiatives. This system significantly reduces
costs and expenses, removes intermediate distribution layers, and integrates
manufacturers with consumers.

     Adatom is working to position itself to become a significant retailer in
Internet retail e-commerce. According to Jupiter Communications, e-commerce is
expected to grow to $108 billion by the year 2003. Adatom has in place a
strategy to seize the opportunities in this space. Adatom has built one of the
largest (in terms of products offered) Internet stores (www.adatom.com) on the
web with over 3 million Stock Keeping Units (SKUs) offered for sale. In
addition, Adatom is not limited solely to those products posted on the
www.adatom.com site but has the ability to source any product from virtually any
brand. Adatom's "Brand Equity" is presently expected to expand to over 1,000
direct shipment manufacturing and distributor suppliers, from the current number
of about 700 by the end of 1999.

     Adatom further intends to leverage its e-commerce content, business
architecture and processes and technical know-how by providing end-to-end
e-commerce solutions and enablement. This consists of site development,
infrastructure implementation, fulfillment and customer service for others
seeking an "instant" on-line retail capability. Adatom intends to serve as the
gateway for e-commerce for a large number of web sites and create new
"e-tailers." Adatom's strategy permits customers to access products through
three distinct channels: direct, indirect and virtual.

     Adatom sells its products at low prices due to its completely scaleable,
low cost infrastructure and distribution system. Adatom's goal is to provide the
customer with superior value by combining the best service with low prices.
Adatom is able to reduce operating costs due to the unique dynamics of
e-commerce. By selling via the Internet and shipping, in most cases, directly
from the manufacturer or supplier, Adatom has eliminated the costs of
intermediaries, maintaining large inventories and staffs, the requirement of
significant physical space fulfillment houses and resultant overhead expense.
This allows Adatom to reduce operating costs and pass value on to the consumer
in the form of increased customer service and price savings.

     The Internet E-tail System is built on four distinct foundations:

     A) CONTENT

     Adatom has established relationships with over 700 qualified suppliers
(manufacturers and distributors) encompassing the complete breadth of durable
goods for home and the office. The aggregated content of product data, images,
prices, shipping detail, etc. constitutes a substantive virtual inventory of
consumer and retail goods. Adatom's supplier relationship most often enables
drop shipment of goods directly from manufactures to the consumer, allowing
Adatom to operate on a lean cost and expense model. Adatom's low cost business
model provides customers with savings on brand name products in some cases of up
to 50% off traditional and Internet retailers. Both Adatom's huge selection of
products and product mix distinguish it

                                       64
<PAGE>
from its competitors and includes many non-commodity, high quality and value
added items that are not typically sold over the Internet. Adatom intends to be
the premier Internet site for furniture and has established close relationships
with many leading manufacturers.

     Most items are shipped from the manufacturer or supplier directly to the
customer, eliminating the cost of maintaining warehouses and operating a
distribution network. All shipping is outsourced to third parties and is paid by
the customer, with a reasonable profit to Adatom on a number of items. Adatom
has also developed a network of deluxe shippers whereby certain large ticket
items will be unwrapped from the original factory packaging, inspected,
polished, and delivered to the home where it will be assembled and installed.

     B) e-COMMERCE INFRASTRUCTURE

     Adatom has built a proprietary e-commerce infrastructure from the ground
up, designed to stage and enable the sale of millions of products online. The
underlying architecture is scaleable and modular, enabling aggregation as well
as rapid partitioning by product categories as needed. The openness of the
system ensures easy interactions with suppliers, affiliates and customers, and
the system is portable to re-launch in alternate environments. The technical
design of the system enables affiliate accounts, customer accounts, electronic
charging and payment, efficient product data uploads and exports, order
processing, and order status reporting to customers and affiliates. In
particular, Adatom has the ability to concurrently host multiple e-commerce
environments utilizing its master products and customer database. Closely linked
to the Adatom e-commerce engine is a proprietary Adatom Information Management
System, which monitors and reports on all aspects of Adatom's interaction with
the customer and partners. One important component of customer interaction is

                                       65
<PAGE>
a web-based software program called R2I which is integrated into every aspect of
Adatom's operation and is designed to catalog and satisfy a customer's
requirements. Finally, Adatom is in the process of developing new standards for
interactions with portal partners using XML (Extensible Markup Language).

     C) BUSINESS PROCESSES

     The third foundation to Adatom's Internet E-tail System is the
standardization of business processes within Adatom to ensure operational
efficiency in the processing and servicing of customer needs. Each aspect of a
business process is rigorously analyzed and implemented as a system. The
activities of each process are detailed and the specific tasks identified.
Metrics are then associated with each task to quantify its usage of resources.
This ensures that there is a clear understanding of the costs of each process,
so that continuous refinement, automation and other efficiencies can be targeted
and implemented. The intent is to enable rapid scalability for fulfillment
without the proportional need for human resources.

     D) CHANNELS

     With the above three foundations of Adatom's Internet E-tail System in
place, Adatom believes it is well positioned to deploy its products and services
in the following three channels:

     (1) Adatom.com Direct

     Adatom's Direct channel links to Adatom's web site (www.adatom.com)
directly. This site trademarked as "Home Dimensions" contains one of the largest
selections online for consumer durable goods. These products are backed by a 30
day "Adatom.com 100% Satisfaction Guarantee," in addition to the manufacturer
warranty. Adatom's value proposition to the customer is "Selection, Price and
Personal Service." The heart of Adatom's strategy is to offer the customer a
blend of cost savings, a friendly shopping experience, personal interaction,
quality products and excellent service that will create loyalty and trust. To
help generate repeat sales, Adatom intends to institute a system where points
awarded with each purchase can be used for discounts on future purchases.

     Adatom is staffed with company trained Personal Shopping Consultants who
assist customers in their shopping experience. The PSC performs many of the
functions typically associated with a sales person in the traditional retail
environment such as helping the customer navigate through a store, answering
questions regarding products, suggesting additional items, and generally
assisting with the mechanics of a transaction. The PSC will also update the
customers on purchase or shipment information as well as notify them of items of
special interest that becomes available. Finally, the PSC can also perform a
"special order" function whereby products that are not part of Adatom's
electronic product inventory can be located in many cases, ordered, and shipped
to the customer, often at substantial discounts to traditional retail prices. In
order to encourage and enhance customer interaction, Adatom has developed a
proprietary two-way interactive keyboard chat software. This enables the
customer to obtain immediate responses from a PSC. The software also allows the
PSC to identify specific customer needs within the Adatom product offerings and
guide the customer through a "push" technology, which showcases the relevant
products on the customer's computer screen.

     Once at Adatom's Internet site, many customer friendly features are
designed to develop loyalty and ensure repeat business. These features include
telephone or chat-room communication with Personal Shopping Consultants, product
search systems, and easy-to-navigate icon or "key word" architecture. Adatom's
software will also allow customers to access bridal or shopper registries.
Finally, Adatom has a special section that features gifts for special occasions
and holidays. Although Adatom believes that its infrastructure is in the
forefront of current Internet and computer technology, it is not dependent on
developing additional new or proprietary technology to succeed, and most
Internet capable computers can access Adatom's web site without additional
hardware or software.

     (2) Affiliate Channel

     Adatom's Affiliate Channel is a revenue sharing program designed to develop
its customer base and create an immediate market presence with minimal
acquisition costs. Adatom has developed revenue sharing arrangement with
organizations through an expanded network of strategic marketing arrangements.
These organizations generally receive a percentage of the proceeds generated
from sales to the partners' customer

                                       66
<PAGE>
base and/or a monthly fee. This strategy is intended not only to develop a large
customer base for Adatom, but also to offer these organizations the opportunity
to receive income at no additional cost.

     Adatom considers these organizations an important strategic alliance and
believes that this strategy will generate a high volume of sales as well as
create brand awareness and Internet visibility for Adatom.com. In addition,
Adatom's close affiliation with these organizations is intended to build
customer loyalty as Adatom becomes associated with an organization and not
merely considered a retail site. Finally, this strategy will also enhance
Adatom's first mover advantage and help to prevent competitors from accessing
Adatom's client base. Some of Adatom's marketing affiliates are shown below:

</TABLE>

     At the Yahoo, Lycos and Excite sites, Adatom is represented as a branded
store, which enables Adatom to gain and enhance its brand identity. Other
affiliate models include linkages to the Adatom store site or links for
fulfillment of specific products or product categories.

     (3) Adatom Virtual E-Tail Channel (AVEC)

     AVEC is a program intended to create Internet stores on web sites of other
organizations. Adatom through its AVEC program will work with others to create
and manage their e-tail business. This is a template-driven automated program
leading to a branded custom store for the other organization from the mix of
products available to Adatom. The partner can chose the particular set of
products to sell under its own brand name, with Adatom providing all the
associated hosting and fulfillment services. This allows companies to launch
their "own" stores with their own name as the host brand name on the web site
with the name "Adatom" completely absent, all without the burden of engaging
suppliers, creating a shopping environment and providing fulfillment and
customer service. Adatom fulfills all purchase, hosting, back office and
customer support operations. The responsibility and cost of customer acquisition
falls to the other organization. The cost to Adatom to enable an e-tailer is
quite low, as the products and order management systems are shared with other
e-tailers including Adatom. Customer support representatives are scaled upon
need, but shared amongst all of Adatom's e-tailers. Computer telephone system
will enable automatic call routing and identification of a specific e-tailer to
the customer service representative.

     The following are the specific features available to AVEC partners:

      1. Ability to select categories, sub-categories and products from Adatom's
         online selection for stocking a new store

      2. Create a store with pre-built design templates

      3. Ability to create a custom store (with Adatom consulting services)

                                       67
<PAGE>
      4. Ability to integrate the store with any existing web presence

      5. Store administration utility (check/change store content, change
         prices, create discounts and promotions, check orders, view user
         sessions)

      6. Customer service provided by Adatom

      7. Ability to follow order history

      8. Flexibility to include new content (products not in Adatom) for
         inclusion

      9. Enablement of Common Adatom Services (two-way chat, feedback systems,
         product queries, special requests, advanced telephony)

     10. Auditing rights to review orders and commissions

     AVEC is anticipated to receive significant attention in the marketplace,
given its ability to launch a new e-tailer very easily. AVEC implementation is
presently intended to be complete in the fourth quarter of 1999. In the
meantime, Adatom is able to implement Virtual Stores as a one-off implementation
for specific clients.

ADATOM AND THE EMERGING MARKETPLACE

     Consumer spending fuels two-thirds of the economy, and the Internet is
quickly becoming a noteworthy component of this spending. With increasing
frequency, customers are embracing the Internet as a means to find information
and purchase a wide range of products and services. Forrester Research, based on
reports from retailers and anecdotal evidence, indicates that Internet retail
shopping is growing significantly and will continue to grow as consumers opt to
browse the Web for purchases. Furthermore, Forrester projects that in 2003,
Internet shopping revenues will increase to $108 billion, or 6% of total
domestic consumer spending, which is estimated to be $1.8 trillion.

     Shopping on the Internet offers both consumers and retailers distinct
advantages over their traditional "off-line" brick-and-mortar or catalogue
competitors. Consumers benefit from the growing sophistication of the Internet,
and its e-commerce capabilities are making it possible to find the right product
or service quickly and efficiently from their computer. Much of the acceptance
and proliferation of e-commerce has to do with the growing sophistication and
reliability of the Internet itself and the usefulness of the software that runs
on it, which allow shoppers to do intricate searches, view merchandise from a
variety of angles, and unearth key buying information. By analyzing consumer
requirements for acquiring goods and services, Adatom believes it has developed
its own innovative retail business model and created a superior shopping
environment that has the potential to become the market leader.

     According to Jupiter Communications, 77% of buyers are going online with a
specific purchase in mind, and 79% of those shoppers visit several sites before
making a purchase. The ability to reduce costs and lower prices while preserving
quality, service, and selection, will facilitate Adatom's success since in
nearly every product category, pricing is the single most important driver
behind a consumer's buying decision. Pricing flexibility is an important feature
that will be exploited by Adatom to generate sales revenues and maximize
profitability. The revenue benefit resulting from a price change must outweigh
the costs incurred in changing the price. The Internet greatly reduces the costs
associated with price changes.

Traditional off-line brick-and-mortar merchants, as well as direct mail
businesses, do not alter prices frequently because it is too costly to do so.
Adatom on the other hand has an advantage over these off line merchants in that
it can rapidly change prices in response to the competitive dynamics of the
market. Adatom is also able to gather competitive information and monitor price
movements with less difficulty than these off line merchants. The speed and ease
with which Adatom can gather pricing data and alter their own prices enables
Adatom to determine the most efficient price to sell a particular product,
thereby maximizing profitability. Many methods to vary price are available to
Adatom to generate sales and maximize profits. Among them are: change the base
list price, discount the base list price, discount shipping, offer volume
discounts or cross promotions. Finally, new information, such as supply, demand,
competitive alternatives and the stage of the product in its lifecycle can be
incorporated into pricing decisions.

                SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS,
                        DIRECTORS AND OFFICERS OF ADATOM

     The following table sets forth certain information as of September 13,
1999, based on information obtained from the persons named below, with respect
to the beneficial ownership of shares of Adatom common stock by (i) each person
known by Adatom to beneficially own more than 5% of the outstanding shares of
Adatom common stock, (ii) each executive officer and director of Adatom, and
(iii) all officers and directors of Adatom as a group.

     Beneficial ownership is defined in accordance with the rules of the SEC and
generally means the power to vote and/or to dispose of the securities regardless
of any economic interest therein. In computing the number and percentage
ownership of shares of common stock beneficially owned by a person, shares of
common stock subject to options or warrants held by that person that are
excisable within 60 days are deemed outstanding. Such shares of common stock,
however, are not deemed outstanding for purposes of computing the percentage
ownership of stockholders other than such person. In calculating beneficial
ownership of HealthCore after the merger, we have assumed that there will be
13,346,228, shares outstanding based on the number of shares of Adatom common
stock to be outstanding immediately prior to the merger, after giving effect
immediately prior to the merger to the issuance of certain shares of Adatom
common stock, including certain new issuances, shares issued upon conversion of
Adatom convertible debentures and upon conversion of $1,800,000 of shareholder
debt and shares issued upon exercise of warrants to purchase Adatom common stock
and the fixed exchange ratio in the merger of approximately 2.17 shares for each
share of Adatom.com, Inc. common stock for each share of Adatom common stock.

EMPLOYMENT AGREEMENTS

     In September 1998, HealthCore entered into an employment agreement with
Neal J. Polan, the Chairman and Chief Executive Officer of HealthCore. The
initial term of the agreement expires on November 30, 2000 and is automatically
renewable for successive one year terms unless terminated by either party.
Pursuant to the agreement, Mr. Polan is not required to devote more than 50% of
his working time to his responsibilities at HealthCore. The employment agreement
with Mr. Polan provides for an annual base salary of $200,000 plus an annual
bonus to be approved by the Board of Directors. The agreement also provides that
Mr. Polan is entitled to certain expenses, including an automobile and the costs
related thereto and the costs of the yearly premium on a term life insurance
policy in the amount of $2,000,000. During the initial term, Mr. Polan's
employment can only be terminated for cause or in the event of Mr. Polan's death
or incapacity. In connection with the merger, Mr. Polan amended his existing
employment agreement with HealthCore. The amended employment agreement reduces
the amount of severance upon termination of employment and provides that
HealthCore would only have to pay Mr. Polan the lesser of $150,000 or 60% of the
remaining value of the contract at the time of termination. In consideration for
agreeing to the amended employment agreement, Mr. Polan received 165,000 shares
of HealthCore class A common stock. to provide that he may be terminated without
cause. Mr. Polan will receive registration rights covering these shares. It is a
condition to the closing that HealthCore terminate this agreement. In addition,
Mr. Polan will receive registration rights covering the shares of HealthCore
common stock he received.

     In May 1998, HealthCore and David L. Mullikin, the President, Chief
Operating Officer and acting Chief Financial Officer, entered into a letter
agreement. The letter agreement provides for an annual base salary of $150,000,
plus a performance related bonus at the discretion of the Board of Directors. In
addition, as part of Mr. Mullikin's compensation, Mr. Mullikin received 10,000
shares of class A common stock at a purchase price of $.01 per share. Pursuant
to the agreement, Mr. Mullikin has the right to receive certain medical,
retirement and other benefits. Mr. Mullikin has agreed not to compete with
HealthCore for a period of one year following the termination of his employment
for any reason. In the event Mr. Mullikin's employment is terminated by
HealthCore, other than for cause, Mr. Mullikin will be entitled to receive his
base salary for a period of one year following the date of termination (subject
to certain offsets for income received by Mr. Mullikin from subsequent
employment during such one year period). In connection with the merger,
Mr. Mullikin amended his existing employment agreement with HealthCore to
provide that he may be terminated without cause. Mr. Mullikin will receive a
lump sum cash payment of $100,000 and options to purchase 100,000 shares of
class A common stock at $.10 per share. It is a condition to the closing that
HealthCore terminate this agreement. In addition, Mr. Mullikin will receive
registration rights covering the shares underlying these options.

     If the merger is consummated, Richard Barton will become the President and
CEO of the combined company. Under an employment agreement to be effective at
the time of the merger, he will receive a salary of $200,000 per year and will
be eligible for a bonus of up to $100,000 per year based on attainment of
performance criteria to be established by the Board of Directors. If there is a
change of control of the combined company, under certain circumstances Mr.
Barton may resign and will be entitled to up to three years of severance pay.
The other two executive officers of the combined company, Sridhar Jagannathan
and Michael Wheeler, will not have employment agreements. It is presently
anticipated that their annual salaries will be $120,000 and $100,000,
respectively.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     In November 1996, MegaVision sold 360 units of limited liability company
interest (which were converted into 216,000 shares of class B common stock in
connection with the merger of MegaVision into HealthCore) to Neal J. Polan,
HealthCore's Chairman of the Board and Chief Executive Officer, for $6,300 in
cash and for certain consulting services rendered by Mr. Polan.

     Between January and February 1997, Mr. Polan loaned an aggregate of
approximately $67,000 to HealthCore for working capital purposes. Such loans
were repaid together with interest at 10% per annum in March 1997 with a portion
of the proceeds of the bridge financing.

     Mr. Polan and his wife, jointly, and Eli Levitin, a director of HealthCore,
invested $50,000 and $25,000, respectively, in the bridge financing in March
1997 (on the same terms as non-affiliated investors) and, accordingly, each
received a Bridge Note in such amount, which was repaid from the proceeds of
HealthCore's initial public offering, and 25,000 and 12,500 bridge warrants,
respectively, which were exchanged for 25,000 and 12,500 Class A Warrants to
purchase Class A Common Stock, respectively, upon the completion of HealthCore's
initial public offering.

     In June 1997, Mr. Polan and Theodore White, Jr., a former employee of
HealthCore, entered into a voting agreement pursuant to which Mr. Polan was
entitled to vote all of the shares of common stock held by Mr. White. The voting
proxy expired on December 31, 1998 as a result of HealthCore's minimum pretax
income being less than $1,000,000.

     For the period from January 1997 until July 1998, HealthCore paid an entity
formerly affiliated with Mr. Polan approximately $1,000 per month as rent for
the use of certain space in New York, New York.

     In September 1997, HealthCore granted warrants to purchase 284,000 shares
of Class A Common Stock to Mr. Polan. The warrants are exercisable at a price of
$1.00 per share and expire in September 2007. Warrants to purchase 142,000 of
such shares of Class A Common Stock will become exercisable if, and only if, one
or more of the following conditions are met: (i) HealthCore's Minimum Pretax
Income amounts to at least $5,500,000 for the fiscal year ending September 30,
1999; (ii) HealthCore's Minimum Pretax Income amounts to at least $7,500,000 for
the fiscal year ending September 30, 2000; (iii) the Closing Price (as defined
in the Escrow Agreement) of the Class A Common Stock averages in excess of
$12.50 per share for 30 consecutive business days during the 18-month period
commencing on the date of HealthCore's initial public offering or (iv) the
Closing Price of the Class A Common Stock averages in excess of $16.50 per share
for 30 consecutive business days during the 18-month period commencing with the
nineteenth month from the date of HealthCore's initial public offering. See
"Security Ownership of Certain Beneficial Owners and Management--Escrow Shares."

     In October 1997, HealthCore granted warrants to purchase 15,000 shares of
Class A Common Stock to Mr. Levitin as compensation for performing investor
relations services for HealthCore. The warrants are immediately exercisable at a
price of $5.00 per share and expire in October 2007.

     Mr. Polan devotes approximately 50% of his business time to our business
activities. Mr. Polan devotes approximately 50% of his business time to
investments outside of HealthCore, some of which are or may be in the health
care services field. In the course of his activities, Mr. Polan may occasionally
be presented with various business opportunities in the health care services
industry. Mr. Polan may present certain of these opportunities to our business,
although Mr. Polan has no agreement to do so and we can not be certain that any
such opportunities will ever be presented to us. These arrangements and
agreements may give rise to certain conflicts of interest.

     In connection with the employment of David L. Mullikin, HealthCore's
President, Chief Operating Officer and acting Chief Financial Officer, in May
1998, HealthCore sold 10,000 shares of Class A Common Stock to Mr. Mullikin for
$100 in cash in June 1998.

     HealthCore believes that all of the transactions set forth above were made
on terms no less favorable to HealthCore than could have been obtained from
unaffiliated third parties. HealthCore has adopted a policy that all future
transactions between HealthCore and its officers, directors, principal
stockholders and their affiliates will be approved by a majority of the Board of
Directors, including a majority of the independent and disinterested outside
directors on the Board of Directors, and will continue to be on terms no less
favorable to HealthCore than could be obtained from unaffiliated third parties.

          DESCRIPTION OF HEALTHCORE CAPITAL STOCK FOLLOWING THE MERGER

     Upon consummation of the merger, the certificate of incorporation of
HealthCore will become the certificate of incorporation of the surviving company
and HealthCore will issue shares of common stock to holders of Adatom common
stock. The shares of Adatom common stock outstanding prior to the merger will
automatically become shares of HealthCore and are referred to in this section as
HealthCore common stock.

HEALTHCORE COMMON STOCK

     The HealthCore certificate of incorporation currently authorizes the
issuance of 20,000,000 shares of common stock consisting of 19,640,000 shares of
HealthCore class A common stock 360,000 share of HealthCore class B common stock
and 5,000,000 shares of preferred stock. On the record date, there were
3,183,000 shares of HealthCore class A common stock and 216,000 shares of class
B common stock issued and outstanding. As part of the merger, the authorization
of class B common stock will be eliminated and class A common stock will be
renamed common stock.

     The Board of Directors of HealthCore has approved, subject to adoption by
its stockholders, an amendment to Article FOURTH of HealthCore's Amended and
Restated Certificate of Incorporation which would make the following changes in
the capital structure of HealthCore:

          o eliminate the authorization of class B common stock and rename the
            class A common stock to common stock

          o increase the authorized number of shares of common stock to 50
            million shares.

     HealthCore is expected to issue approximately 10,689,489 shares of
HealthCore common stock to holders of Adatom common stock in the merger,
including 50,661 shares issuable upon exercise of a warrant. Based upon such
number and the number of shares of HealthCore class A and class B common stock
outstanding on the record date, there would be approximately 13,346,228 shares
of HealthCore common stock outstanding immediately following consummation of the
merger and transactions contemplated thereby.

     Holders of shares of HealthCore common stock will be entitled to one vote
per share and for each matter to be voted on generally by the stockholders.
Subject to the rights of the holders of preferred stock, holders of shares of
HealthCore common stock have equal rights to participate in dividends when
declared and, in the event of liquidation, in the net assets of HealthCore
available for distribution to stockholders.

     The shares of HealthCore common stock, when issued to holders of
outstanding shares of Adatom common stock in connection with the merger, will be
duly authorized, validly issued, fully paid and non-assessable. The holders of
shares of HealthCore common stock have no preemptive rights or preferential
rights of subscription for any shares of HealthCore common stock or other
securities of HealthCore.

     American Stock Transfer & Trust Company is the transfer agent and registrar
for the HealthCore common stock.

REDEEMABLE CLASS A WARRANTS

     HealthCore currently has outstanding Class A Warrants for the purchase of
3,766,500 shares of Class A common stock. Each Class A Warrant entitles the
registered holder to purchase one share of Class A Common Stock at an exercise
price of $6.50 at any time until 5:00 P.M., New York City time, on October 14,
2002. Commencing on October 14, 1998, the Class A Warrants became redeemable by
HealthCore on 30 days' written notice at a redemption price of $.05 per Class A
Warrant if the "closing price" of HealthCore's Class A Common Stock for any 30
consecutive trading days ending within 15 days of the notice of redemption
averaged in excess of $9.10 per share. The "closing price" is the closing bid
price if listed in the over-the-counter market on Nasdaq or otherwise or the
closing sale price if listed on the Nasdaq National Market or a national
securities exchange. All Class A Warrants must be redeemed if any are redeemed.

     The Class A Warrants were issued pursuant to a warrant agreement (the
"Warrant Agreement") among HealthCore, D.H. Blair Investment Banking Corp.
("Blair") and American Stock Transfer & Trust Company, New York, New York, as
warrant agent (the "Warrant Agent"), and was evidenced by warrant certificates
in registered form. The Class A Warrants provide for adjustment of the exercise
price and for a change in the

                                       77
<PAGE>
number of shares issuable upon exercise to protect holders against dilution in
the event of a stock dividend, stock split, combination or reclassification of
the Common Stock or upon issuance of shares of Common Stock at prices lower than
the market price of the Common Stock, with certain exceptions.

     The exercise price of the Class A Warrants was determined by negotiation
between HealthCore and Blair and should not be construed to be predictive of or
to imply that any price increases in HealthCore's securities will occur.

     HealthCore has reserved from its authorized but unissued shares a
sufficient number of shares of Class A Common Stock for issuance upon the
exercise of the Class A Warrants. A Class A Warrant may be exercised upon
surrender of the Warrant certificate on or prior to its expiration date (or
earlier redemption date) at the offices of the Warrant Agent, with the form of
"Election to Purchase" on the reverse side of the Warrant certificate completed
and executed as indicated, accompanied by payment of the full exercise price (by
certified or bank check payable to the order of HealthCore) for the number of
shares with respect to which the Warrant is being exercised. Shares issued upon
exercise of Class A Warrants and payment in accordance with the terms of the
Warrants will be fully paid and non-assessable.

     For the life of the Class A Warrants, the holders thereof have the
opportunity to profit from a rise in the market value of the Class A Common
Stock, with a resulting dilution in the interest of all other stockholders. So
long as the Class A Warrants are outstanding, the terms on which HealthCore
could obtain additional capital may be adversely affected. The holders of the
Class A Warrants might be expected to exercise them at a time when HealthCore
would, in all likelihood, be able to obtain any needed capital by a new offering
of securities on terms more favorable than those provided for by the Warrants.

     The Class A Warrants do not confer upon the Warrantholder any voting or
other rights of a stockholder of HealthCore. Upon notice to the Warrantholders,
HealthCore has the right to reduce the exercise price or extend the expiration
date of the Class A Warrants.

PREFERRED STOCK

     HealthCore is authorized to issue up to 5,000,000 shares of "blank-check"
preferred stock (the "Preferred Stock"). The Board of Directors has the
authority to issue this Preferred Stock in one or more series and to fix the
number of shares and the relative rights, conversion rights, voting rights and
terms of redemption (including sinking fund provisions) and liquidation
preferences, without further vote or action by the stockholders. If shares of
Preferred Stock with voting rights are issued, such issuance could affect the
voting rights of the holders of HealthCore's Common Stock by increasing the
number of outstanding shares having voting rights, and by the creation of class
or series voting rights. If the Board of Directors authorizes the issuance of
shares of Preferred Stock with conversion rights, the number of shares of Common
Stock outstanding could potentially be increased by up to the authorized amount.
Issuance of Preferred Stock could, under certain circumstances, have the effect
of delaying or preventing a change in control of HealthCore and may adversely
affect the rights of holders of Common Stock. Also, Preferred Stock could have
preferences over the Common Stock (and other series of preferred stock) with
respect to dividend and liquidation rights. HealthCore currently has no plans to
issue any Preferred Stock.

UNIT PURCHASE OPTION

     HealthCore has issued to Blair, a Unit Purchase Option to purchase up to
176,000 Units. Each Unit consists of one share of Class A Common Stock and one
redeemable Class A Warrant. The Warrants included in the Unit Purchase Option
are only subject to redemption by HealthCore after the Unit Purchase Option is
exercised and the underlying Warrants are outstanding. The Unit Purchase Option
is not transferable until October 14, 2000, except to any officer of Blair or
members of the selling group or their respective officers. The Unit Purchase
Option is exercisable during the two-year period commencing October 14, 2000 at
an exercise price of $6.00 per Unit (120% of the initial public offering price)
subject to adjustment in certain events to protect against dilution. The holders
of the Unit Purchase Option have certain demand and piggyback registration
rights.

OTHER WARRANTS

     In September 1997, HealthCore granted warrants to purchase 284,000 shares
of Class A Common Stock to Mr. Polan. The warrants are exercisable at a price of
$1.00 per share and expire in September 2007. Warrants to purchase 142,000 of
such shares of Class A Common Stock will become exercisable if, and only if, one
or more of the following conditions are met: (i) HealthCore's Minimum Pretax
Income amounts to at least $5,500,000 for the fiscal year ending September 30,
1999; (ii) HealthCore's Minimum Pretax Income amounts to at least $7,500,000 for
the fiscal year ending September 30, 2000; (iii) the Closing Price (as defined
in the Escrow Agreement) of the Class A Common Stock averages in excess of
$12.50 per share for 30 consecutive business days during the 18-month period
commencing on the date of HealthCore's initial public offering or (iv) the
Closing Price of the Class A Common Stock averages in excess of $16.50 per share
for 30 consecutive business days during the 18-month period commencing with the
nineteenth month from the date of HealthCore's initial public offering.

     In October 1997, HealthCore granted warrants to purchase 15,000 shares of
Class A Common Stock to Mr. Levitin as compensation for performing investor
relations services for HealthCore. The warrants are immediately exercisable at a
price of $5.00 per share and expire in October 2007.

     In April 1999, HealthCore agreed to grant to Jesup & Lamont Securities
Corporation, as compensation for acting as financial advisor to HealthCore, a
warrant to purchase 200,000 shares of HealthCore common stock at an exercise
price of $1.00 per share. One half of these warrants was granted in April 1999
upon the execution of the engagement letter with Jesup & Lamont, and the
remaining one half will be granted upon the closing of the merger with Adatom.
The warrants will be immediately exercisable and expire five years from the date
of issue. The holders of the warrants will have unlimited "piggyback"
registration rights, subject to standard underwriters' approval and contain,
among other things, a cashless exercise provision.

     In July 1999, Adatom agreed to grant to Jesup & Lamont Securities
Corporation, as compensation for acting as placement agent in the recent
convertible debt financing by Adatom, a warrant to purchase 23,315 shares of
Adatom common stock at an exercise price of $2.1447 per share. Upon consummation
of the merger with HealthCore, this warrant will be converted into a warrant to
purchase 50,661 shares of HealthCore at an exercise price of $.99 per share. The
warrants are immediately exercisable and expire on July 8, 2004. The holders of
the warrants have unlimited "piggyback" registration rights, subject to standard
underwriters' approval and contain, among other things, a cashless exercise
provision.

NASDAQ SMALL CAP MARKET MATTERS

     It is a covenant of the merger that HealthCore and Adatom use their
respective best efforts to cause the shares of HealthCore common stock that will
be issued in connection with the merger to be approved for listing on the Nasdaq
Small Cap Market, subject to official notice of issuance. Application has been
made to list the HealthCore common stock to be issued in the merger on the
Nasdaq Small Cap Market, subject to official notice of issuance.

     After the merger, the surviving company may be deemed to be a new company
required to meet the criteria for initial listing of securities on the Nasdaq
Small Cap Market. These initial listing criteria generally include either a
minimum of $4 million in net tangible assets, or $50 million in market
capitalization or $750,000 in net income in the latest fiscal year or two of the
last three fiscal years. In addition, the common stock must have at least three
registered and active market makers, be held by at least 300 round lot holders,
have a public float of at least one million shares, and have a minimum bid price
of $4.00. Finally, the market value of the public float must be at least $5
million. Jesup & Lamont Securities Corporation has been engaged to raise
$5.5 million through an equity securities offering which, if accomplished, will
dilute all stockholders.

     If the surviving company does not meet the initial inclusion criteria,
which we expect it will not, immediately following the merger, it risks having
its common stock delisted. If this occurs, trading in the common stock would be
conducted in the over-the-counter market in the so-called "pink sheets" or, if
available, the "OTC Bulletin Board Service." As a result, an investor would
likely find it more difficult to dispose of, or to obtain accurate quotations as
to the value of, HealthCore's securities. Even if Jesup & Lamont is successful
in raising the money mentioned above, the common stock may be delisted before
the money is raised.

     In addition, if HealthCore's securities were delisted, they would be
subject to Rule 15c2-6 under the Securities Exchange Act of 1934, which imposes
additional sales practice requirements on broker-dealers who sell such
securities to persons other than established customers and "accredited
investors." For transactions covered by this Rule, the broker-dealer must make a
special suitability determination for the customer and have received the
customer's written consent to the transaction prior to sale. Consequently, such
Rule may affect the ability of broker-dealers to sell HealthCore's securities
and may affect the ability of stockholders to sell any of the securities
acquired in the merger in the secondary market.

                             1999 STOCK OPTION PLAN

GENERAL

     In connection with the merger, the Board of Directors, subject to
stockholder approval, adopted the 1999 Stock Option Plan under which an
aggregate of 1,400,000 shares of surviving company common stock is reserved for
issuance upon exercise of options granted to selected employees, consultants,
officers, directors, independent contractors and other persons who contribute
and are expected to contribute materially to the success of the surviving
company. Incentive stock options that qualify under Section 422 of the Internal
Revenue Code and/or non-qualified stock options that do not so qualify may be
granted under the 1999 Stock Option Plan.

     The purpose of the 1999 Stock Option Plan is to further the growth and
development of the surviving company by encouraging those granted options to
obtain a proprietary interest in the surviving company through the ownership of
stock, thereby providing such persons with an added incentive to promote the
long-term financial interests of the surviving company and enhancement of
long-term stockholder return. The 1999 Stock Option Plan is further intended to
afford the surviving company a means of attracting to its service persons of
outstanding ability.

SUMMARY OF THE 1999 STOCK OPTION PLAN

     Administration of the 1999 Stock Option Plan

     The authority to manage and control the operation and administration of the
1999 Stock Option Plan is vested in the Compensation Committee of the Board of
Directors, which shall consist of not less than two, non-employee, independent
directors.

     Eligibility

     Incentive Stock Options may be granted only to employees (including
officers) of the surviving company and/or any of its subsidiaries. To qualify as
an ISO under the Internal Revenue Code, among other things, the aggregate fair
market value, determined as at the date of grant, of the shares exercisable
under the ISO for the first time by the employee during any calendar year
(inclusive of shares under any other ISOs granted to the employee) can not
exceed $100,000; any excess will not qualify for treatment as an ISO. In the
event an ISO or a portion thereof no longer qualifies as such under the Code,
such former ISO, or portion thereof, as applicable, shall be deemed a
Non-Qualified Stock Option under the 1999 Stock Option Plan.

     Non-Qualified Stock Options may be granted to any person (including
employees who have been granted ISOs) whom the Committee determines will
contribute to the success of the surviving company or its subsidiaries.

     Grant of Options

     Pursuant to the 1999 Stock Option Plan, the Committee selects those persons
to be granted options and determines (i) whether the respective option is to be
an ISO or NQSO, (ii) the number of shares of common stock purchasable
thereunder, (iii) the time or times when the option becomes exercisable, (iv)
the exercise price per share, which for ISOs cannot be less than 100% and for
NQSOs cannot be less than 75% of the fair market value on the date of grant, and
(v) the duration of the option, which cannot exceed ten years. For purposes of
the 1999 Stock Option Plan, "fair market value" of a share of common stock as of
a specified date is the closing sales price of the common stock on the Nasdaq
Small Cap Market (or on such other public market on which the common stock may
then be traded) on the trading day immediately preceding the specified date.

     Each grant of an option will be evidenced by a written stock option
agreement setting forth the terms and conditions of the option, including
whether it is an ISO or NQSO. Nothing in the 1999 Stock Option Plan nor in the
stock option agreement evidencing the grant of the ISO and/or NQSO shall confer
upon the

                                       81
<PAGE>
holder any right to continue in the employ of the surviving company or obligate
the surviving company to continue the engagement of the holder.

     Section 162 (m) of the Code places limits on the deductibility for federal
income tax purposes of compensation paid to certain executive officers of the
surviving company. In order to preserve the surviving company's ability to
deduct the compensation income associated with options, the 1999 Stock Option
Plan limits the number of shares as to which options may be granted under the
Plan to any employee during any calendar year to a maximum of 700,000 shares.

     Exercise of Options

     Options shall become exercisable on the terms and conditions established by
the Committee as set forth in the written option agreement.

     Payment for the shares may be made (i) in cash, or (ii) by surrender of
shares of common stock having a fair market value equal to the aggregate
exercise price of the shares being purchased. Prior to the issuance of shares
upon exercise of an option, the exercising holder shall be required to pay or
make adequate provision for payment of any federal, state or local withholding
tax obligations. Until the option has been validly exercised, the holder of an
option shall not have any rights of a stockholder of the surviving company with
respect to the shares purchasable thereunder.

     ISOs may be exercised by the holder only while in the employ of the
surviving company or a subsidiary or within three months following termination
of employment unless the termination is due to death or disability, in which
event the ISO may be exercised within twelve (12) months of such event to the
extent the option could have been exercised at the date of termination, but in
no event subsequent to the option's expiration date. The Committee, in its sole
discretion, may extend the time during which an ISO or NQSO may be exercised,
which could have the effect of changing an ISO into a NQSO, and may permit an
ISO or NQSO to be transferred, without consideration, to family members of the
holder of the option or entities for his or their benefit.

     Adjustments

     The 1999 Stock Option Plan contains customary anti-dilution provisions that
provide that in the event of any stock dividend, stock split, reverse stock
split, combination, reclassification or similar change in the capital structure
of the surviving company without consideration, the number of shares of common
stock available under the 1999 Stock Option Plan and the number of shares
subject to outstanding options and the related exercise price per share shall be
proportionately adjusted.

     Amendments to the 1999 Stock Option Plan

     The Committee may at any time amend the 1999 Stock Option Plan in any
respect (including, but not limited to, any form of grant, agreement or
instrument to be executed pursuant thereto); provided, however, that stockholder
approval shall be required to be obtained to increase the number of shares
purchasable under the 1999 Stock Option Plan or if otherwise required by the
Nasdaq Small Cap Market or other entity on which the common stock may then be
traded, and no amendment may adversely affect any then outstanding options or
any unexercised portions thereof without the written consent of the affected
holders.

     Termination of 1999 Stock Option Plan; Successors

     No options may be granted under the 1999 Stock Option Plan subsequent to
September 7, 2009 but options theretofore granted may extend beyond that date
and the terms of the 1999 Stock Option Plan shall continue to apply to such
options and to any shares acquired upon exercise thereof. The 1999 Stock Option
Plan may be sooner terminated at the discretion of the Committee.

                                       82

FEDERAL INCOME TAX CONSEQUENCES

     Incentive Stock Options (ISOs)

     No taxable income is recognized by the recipient of an ISO upon either the
grant or exercise of the ISO (except that the alternative minimum tax may apply
upon exercise) and no expense deduction is available to the surviving company
upon either such event. If the exercising holder of an ISO holds the shares so
acquired for at least two years from the date of grant of the ISO and for at
least one year from the date of exercise, any gain (the excess of the sales
price over the exercise price) on the subsequent sale of such shares will be
long-term capital gain. However, in the event the holder sells the shares prior
to the expiration of either such two-year or one-year period (referred to as a
"disqualifying disposition") the holder will recognize taxable income at
ordinary tax rates in an amount equal to the lesser of (i) the excess of the
fair market value of the shares on the date of exercise over the exercise price,
or (ii) the excess of the sales price over the exercise price, and the surviving
company will receive a corresponding business expense deduction. The balance of
any gain recognized on the disqualifying disposition will be capital gain,
either long-term or short-term depending on the period the shares were held
prior to the sale. The two-year and one year holding periods do not apply to a
holder's estate or heirs in the event of the holder's death.

     Non-Qualified Stock Options (NQSOs)

     As in the case of ISOs, the grant of a NQSO will not result in taxable
income to the recipient. However, unlike the situation with ISOs, the exercising
holder will recognize ordinary income upon the exercise of a NQSO, the amount of
such income being equal to the excess of the fair market value of the shares
received upon exercise over the exercise price, and the surviving company will
be entitled to a corresponding business expense deduction if federal income tax
attributable to such excess is withheld. The fair market value of the shares on
the date income is required to be recognized will constitute the tax basis for
such shares for computing gain or loss on any subsequent sale, which will be
capital gain or loss, either long-term or short-term depending on the holding
period.

     The foregoing is only a summary of the federal income tax consequences with
respect to ISOs and NQSOs which may be granted under the 1999 Stock Option Plan
and does not purport to be complete. Reference should be made to applicable
provision of the Internal Revenue Code. In addition, the summary does not
discuss the tax consequences of the income tax laws of any municipality, state
or foreign country in which the recipient of an option may reside.

                      TERMINATION OF THE ESCROW AGREEMENT

     In connection with HealthCore's IPO, the pre-IPO stockholders of HealthCore
placed, on a pro rata basis, a portion of their shares into escrow pending
HealthCore's attainment of certain earnings thresholds or per share stock price
thresholds. If these thresholds are not met, the shares subject to the escrow
agreement will be returned to HealthCore and cancelled. HealthCore's management
believed that while operating the healthcare benefits business, it was unlikely
that the conditions of the escrow agreement would be met. In connection with the
merger, and subject to stockholder approval, the escrow agreement will be
terminated, the escrow stockholders will receive 20% of their shares free of the
escrow agreement trading restrictions and the remaining 80% of the shares will
be cancelled and returned to HealthCore.

     Approval of the termination of the escrow agreement will require the
approval of at least two-thirds of the shares of class A common stock
outstanding on the record date excluding all shares of class A common stock held
by escrow stockholders whether or not those shares are subject to the escrow
agreement. The termination of the escrow agreement will result in the
cancellation of 720,000 shares held in escrow. In the absence of this
cancellation, Adatom stockholders would have received an additional 3,200,000
shares of HealthCore common stock in the merger and the stockholders who had
placed their 900,000 shares in escrow would continue to be subject to the risk
of forfeiture of those shares in the event the combined company failed to meet
the market price thresholds and operating performance-based criteria.

     In the event the stockholders of HealthCore fail to approve the termination
of the escrow agreement, Adatom stockholders have agreed to vote all of their
shares of the combined company to approve the termination of the escrow
agreement at the first annual or special meeting of the stockholders of the
combined company following the merger.

     In the event the stockholders of HealthCore fail to approve the termination
of the escrow agreement, Adatom stockholders will approve termination of the
escrow agreement at the first annual or special meeting of the stockholders of
the combined company following the merger, which will be called by the combined
company as soon as practicable following the merger.

                           COMPARISON OF RIGHTS OF HOLDERS
               OF ADATOM COMMON STOCK AND HEALTHCORE COMMON STOCK

GENERAL

     If the merger agreement is approved and the merger becomes effective,
Adatom stockholders will become stockholders of Adatom.com, Inc. Their rights as
stockholders will be determined by the Delaware General Corporation Law and
HealthCore's Restated certificate of incorporation and by-laws since they will
be adopted as the certificate of incorporation and by-laws of the surviving
company. Differences between the DGCL and the California Corporation Code, as
well as those between the certificate of incorporation and by-laws of HealthCore
and the articles of incorporation and the by-laws of Adatom, are summarized
below. This summary is not intended to be complete and is qualified in its
entirety by reference to the DGCL, the CCC, and the certificate of incorporation
and by-laws of HealthCore and the articles of incorporation and by-laws of
Adatom.

SIZE OF THE BOARD OF DIRECTORS

     Under California law, the number of directors of a corporation may be fixed
in the articles of incorporation or by-laws of a corporation, or a range may be
established for the number of directors, with the board of directors given
authority to fix the exact number of directors within such range. The Adatom by-
laws provide that there be five directors on the board of directors. Under
Delaware law, the number of directors of a corporation, or the range of
authorized directors, may be fixed or changed by the board of directors acting
alone, by amendment to the corporation's by-laws, unless the directors are not
authorized to amend the by-laws or the number of directors is fixed in the
certificate of incorporation, in which cases stockholder approval is required.
The HealthCore by-laws provides that the number of directors be fixed by the
vote of a majority of the entire board then in office. The exact number is
currently set at four, and HealthCore's by-laws authorize the HealthCore board
to make, alter, amend or repeal the HealthCore by-laws. Accordingly, a majority
of HealthCore's board of directors will have the power to change the authorized
number of directors.

CUMULATIVE VOTING

     Under California law, if any stockholder has given notice of his or her
intention to cumulate votes for the election of directors, any other stockholder
of the corporation also is entitled to cumulate his or her votes at such
election. Cumulative voting is not available under Delaware law unless
specifically provided for in a corporation's certificate of incorporation. The
HealthCore certificate of incorporation does not provide for cumulative voting
and, therefore, the stockholders of the surviving company will no longer have
cumulative voting rights. The elimination of cumulative voting would limit the
ability of minority stockholders to obtain representation on a corporation's
board of directors.

CLASSIFIED BOARD OF DIRECTORS

     A classified board is one on which a certain number, but not all, of the
directors are elected on a rotating basis each year. Under California law,
directors generally are elected annually. Delaware law permits, but does not
require, a classified board of directors, with staggered terms under which
one-half or one-third of the directors are elected for terms of two or three
years, respectively. This method of electing directors makes a change in the
composition of the board of directors, and a potential change in control of a
corporation, a lengthier and more difficult process.

WRITTEN CONSENT OF STOCKHOLDERS

     Both the CCC and the DGCL provide that the stockholders of a corporation
may take action by written consent without a meeting, unless the corporation's
charter documents provide otherwise. The certificate of incorporation of
HealthCore does not contain such a provision.

                                       85
<PAGE>
POWER TO CALL SPECIAL STOCKHOLDERS' MEETINGS

     Under California law, a special meeting of stockholders may be called by
the board of directors, the chairman of the board, the president, the holders of
shares entitled to cast not less than 10% of the votes at such meeting and such
additional persons as are authorized by the articles of incorporation or the
by-laws. Under Delaware law, a special meeting of stockholders may be called by
the board of directors or by any other person authorized to do so in the
certificate of incorporation or the by-laws. The by-laws of HealthCore allow the
board or the holders of at least 20% of the outstanding stock of HealthCore to
call special meetings of the stockholders. This might delay stockholder
proposals until the next annual meeting of stockholders.

STOCKHOLDER APPROVAL OF BUSINESS COMBINATIONS

     In the last several years, a number of states, but not California, have
adopted special laws designed to subject to stockholder approval certain kinds
of "unfriendly" corporate takeovers, or other transactions involving a
corporation and one or more of its significant stockholders.

     Under Section 203 of the DGCL, "business combinations" with "interested
stockholders" of Delaware corporations are subject to a three-year moratorium
unless specified conditions are met. With exceptions, an interested stockholder
is a person or group who or which owns 15% or more of the corporation's
outstanding voting stock, or is an affiliate or associate of the corporation and
was the owner of 15% or more of such voting stock at any time within the
previous three years. Such voting stock includes any rights to acquire stock
pursuant to an option, warrant, agreement, arrangement or understanding, or upon
the exercise of conversion or exchange rights, and stock with respect to which
the person has voting rights only.

     For purposes of Section 203, the term "business combination" is defined
broadly to include:

     1. mergers with or caused by the interested stockholder,

     2. sales or other dispositions to the interested stockholder, except
        proportionately with the corporation's other stockholders, of assets of
        the corporation or a subsidiary equal to 10% or more of the aggregate
        market value of the corporation's consolidated assets or its outstanding
        stock,

     3. the issuance or transfer by the corporation or a subsidiary of stock of
        the corporation or such subsidiary to the interested stockholder, except
        for transfers in a conversion or exchange or a pro rata distribution or
        other transactions, none of which increase the interested stockholder's
        proportionate ownership of any class or series of the corporation's or
        such subsidiary's stock

     4. any increase in the proportionate share of the stock of any class or
        series of the corporation, except as a result of immaterial changes due
        to fractional share adjustments or as a result of any purchase or
        redemption of any shares of stock not caused, directly or indirectly, by
        the interested stockholder, or

     5. receipt by the interested stockholder except proportionately as a
        stockholder, directly or indirectly, of any loans, advances, guarantees,
        pledges or other financial benefits provided by or through the
        corporation or a subsidiary.

     The three-year moratorium imposed on business combinations by Section 203
does not apply if:

     1. prior to the date on which such stockholder becomes an interested
        stockholder the board of directors approves either the business
        combination or the transaction which resulted in the person becoming an
        interested stockholder;

     2. the interested stockholder owns 85% of the corporation's voting stock
        upon consummation of the transaction which made him or her an interested
        stockholder, excluding from the 85% calculation shares owned by
        directors who are also officers of the target corporation and shares
        held by employee stock plans which do not permit employees to decide
        confidentially whether to accept a tender or exchange offer; or

     3. on or after the date such person becomes an interested stockholder, the
        board approves the business combination and it also is approved at a
        stockholder meeting by 66 2/3% of the voting stock not owned by the
        interested stockholder.

                                       86
<PAGE>
     Section 203 only applies to Delaware corporations which have a class of
voting stock that is listed on a national securities exchange, such as the
Nasdaq Small Cap Market or are held of record by more than 2,000 stockholders.
However, a Delaware corporation may elect not to be governed by Section 203 by a
provision in its original certificate of incorporation or an amendment thereto
or to the by-laws, which amendment must be approved by majority stockholder vote
and may not be further amended by the board of directors. HealthCore is
currently subject to Section 203.

REMOVAL OF DIRECTORS

     Under California law, any director or the entire board of directors may be
removed, with or without cause, with the approval of a majority of the
outstanding shares entitled to vote; however, no individual director may be
removed unless the entire board is removed if the number of votes cast against
such removal would be sufficient to elect the director under cumulative voting
and the entire number of directors authorized at the time of the directors most
recent election were then being elected. Under Delaware law, a director of a
corporation that does not have a classified board of directors or cumulative
voting may be removed with or without cause with the approval of a majority of
the outstanding shares entitled to vote. In the case of a Delaware corporation
having cumulative voting, if less than the entire board is to be removed, a
director may not be removed without cause unless the number of shares voted
against such removal would not be sufficient to elect the director under
cumulative voting. A director of a corporation with a classified board of
directors may be removed only for cause, unless the certificate of incorporation
otherwise provides. The by-laws of the surviving company provides for removal of
directors, either with or without cause, by a majority of the votes of the
issued and outstanding shares of stock entitled to vote, or by a majority of the
vote of the Board of Directors at a meeting called for such purpose.

FILLING VACANCIES ON THE BOARD OF DIRECTORS

     Under California law, any vacancy on the board of directors other than one
created by removal of a director may be filled by the board. If the number of
directors then in office is less than a quorum, a vacancy may be filled by
(1) the unanimous written consent of the directors then in office, (2) the
affirmative vote of a majority of the directors at a meeting held pursuant to
notice or waivers of notice or, (3) a sole remaining director. A vacancy created
by removal of a director may be filled by the board only if so authorized by a
corporation's articles of incorporation or by a bylaw approved by the
corporation's stockholders, and if not so authorized, then by approval of the
stockholders. Under Delaware law, vacancies and newly created directorships may
be filled by a majority of the directors then in office, even though less than a
quorum, unless otherwise provided in the certificate of incorporation or by-laws
and unless the certificate of incorporation directs that a particular class is
to elect such director, in which case any other directors elected by such class,
or a sole remaining director, shall fill such vacancy.

LOANS TO OFFICERS AND EMPLOYEES

     Under California law, any loan or guaranty to or for the benefit of a
director or officer of the corporation or its parent requires approval of a
majority of the stockholders unless such loan or guaranty is provided under an
employee benefit plan approved by stockholders owning a majority of the
outstanding shares of the corporation. In addition, under California law,
stockholders of any corporation with 100 or more stockholders of record may
approve a bylaw authorizing the board of directors alone to approve loans or
guaranties to or on behalf of officers, whether or not such officers are
directors, if the board determines that any such loan or guaranty may reasonably
be expected to benefit the corporation. Under Delaware law, a corporation may
make loans to, guarantee the obligations of or otherwise assist its officers or
other employees and those of its subsidiaries, including directors who are also
officers or employees, when such action, in the judgment of the directors, may
reasonably be expected to benefit the corporation.

INDEMNIFICATION AND LIMITATION OF LIABILITY

     California and Delaware have similar laws respecting indemnification by a
corporation of its officers, directors, employees and other agents. The laws of
both states also permit corporations to adopt a provision in their articles of
incorporation eliminating the liability of a director to the corporation or its
stockholders for

                                       87
<PAGE>
monetary damages for breach of the director's fiduciary duty of care. There are
differences between the laws of the two states respecting indemnification and
limitation of liability.

     The Articles of Incorporation of Adatom eliminate the liability of
directors to Adatom to the fullest extent permissible under California law.
California law does not permit the elimination of monetary liability where such
liability is based on:

     1. intentional misconduct or knowing and culpable violation of law;

     2. acts or omissions that a director believes to be contrary to the best
        interest of the corporation or its stockholders, or that involve the
        absence of good faith on the part of the director;

     3. receipt of an improper personal benefit;

     4. acts or omissions that show reckless disregard for the director's duty
        to the corporation or its stockholders where the director in the
        ordinary course of performing a director's duties should be aware of
        risks of serious injury to the corporation or its stockholders;

     5. acts or omissions that constitute an unexcused pattern of inattention
        that amounts to an abdication of the director's duty to the corporation
        and its stockholders;

     6. interested transactions between the corporation and a director in which
        a director has a material financial interest; and

     7. liability for improper distributions, loans or guarantees.

     The certificate of incorporation of HealthCore also eliminates the
liability of directors to the fullest extent permissible under Delaware law, as
such law exists currently or as it may be amended in the future. Under Delaware
law, such provision may not eliminate or limit director monetary liability for:

     1. breaches of the director's duty of loyalty to the corporation or its
        stockholders;

     2. acts or omissions not in good faith or involving intentional misconduct
        or knowing violations of law;

     3. the payment of unlawful dividends or unlawful stock repurchases or
        redemptions; or

     4. transactions in which the director received an improper personal
        benefit.

     Such limitation of liability provision also may not limit a director's
liability for violation of, or otherwise relieve HealthCore or its directors
from the necessity of complying with, federal or state securities laws, or
affect the availability of non-monetary remedies such as injunctive relief or
rescission.

     California law permits indemnification of expenses incurred in derivative
or third-party actions, except that with respect to derivative actions:

     1. no indemnification may be made without court approval when a person is
        adjudged liable to the corporation in the performance of that person's
        duty to the corporation and its stockholders, unless a court determines
        such person is entitled to indemnity for expenses, and then such
        indemnification may be made only to the extent that such court shall
        determine; and

     2. no indemnification may be made without court approval in respect of
        amounts paid or expenses incurred in settling or otherwise disposing of
        a threatened or pending action or amounts incurred in defending a
        pending action which is settled or otherwise disposed of without court
        approval.

     Delaware allows indemnification of such expenses without court approval.
Delaware law generally permits indemnification of expenses incurred in the
defense or settlement of a derivative or third-party action, provided there is a
determination by a disinterested quorum of the directors, by independent legal
counsel or by a majority vote of a quorum of the stockholders that the person
seeking indemnification acted in good faith and in a manner reasonably believed
to be in or, in contrast to California law, not opposed to the best interests of
the corporation. Without court approval, however, no indemnification may be made
in respect of any derivative action in which such person is adjudged liable for
negligence or misconduct in the performance of his or her duty to the
corporation. Delaware law requires indemnification of expenses when the
individual being indemnified has successfully defended the action on the merits
or otherwise.

                                       88
<PAGE>
     Indemnification is permitted by California law only for acts taken in good
faith and believed to be in the best interests of the corporation and its
stockholders, as determined by a majority vote of a disinterested quorum of the
directors, independent legal counsel, if a quorum of independent directors is
not obtainable, a majority vote of a quorum of the stockholders excluding shares
owned by the indemnified party, or the court handling the action. California law
requires indemnification when the individual successfully has defended the
action on the merits as opposed to Delaware law which requires indemnification
relating to a successful defense on the merits or otherwise.

     California corporations may include in their articles of incorporation a
provision which extends the scope of indemnification through agreements, by-laws
or other corporate action beyond that specifically authorized by statute.
Delaware law states that the indemnification provided by statute shall not be
deemed exclusive of any other rights under any bylaw, agreement, vote of
stockholders or disinterested directors or otherwise. Under Delaware law,
therefore, any indemnification agreements entered into by Adatom with its
officers and directors may be assumed by HealthCore upon completion of the
merger.

     Currently, there are no actions pending against any officers of Adatom in
their capacities as such.

INSPECTIONS OF STOCKHOLDERS LIST

     Both California and Delaware law allow any stockholder to inspect the
stockholders list for a purpose reasonably related to such person's interest as
a stockholder. California law provides, in addition, for an absolute right to
inspect and copy the corporation's stockholder list by persons holding an
aggregate of 5% or more of a corporation's voting shares, or stockholders
holding an aggregate of 1% or more of such shares who have filed a Schedule 14B
with the SEC relating to the election of directors. Delaware law does not
provide for any such absolute right of inspection, and no such right is granted
under the certificate of incorporation or By-laws of HealthCore. Lack of access
to stockholder records, even though unrelated to the stockholder's interest as a
stockholder, could result in impairment of the stockholder's ability to
coordinate opposition to management proposals, including proposals with respect
to a change in control of HealthCore.

DIVIDENDS AND REPURCHASES OF SHARES

     California law dispenses with the concepts of par value of shares as well
as statutory definitions of capital, surplus and the like. The concepts of par
value, capital and surplus are retained under Delaware law. Under California
law, a corporation may not make any distribution, including dividends, whether
in cash or other property, and repurchases of its shares, unless either the
corporation's retained earnings immediately prior to the proposed distribution
equal or exceed the amount of the proposed distribution or, immediately after
giving effect to such distribution, the corporation's assets, exclusive of
goodwill, capitalized research and development expenses and deferred charges,
would be at least equal to 1.25 times its liabilities, not including deferred
taxes, deferred income and other deferred credits, and the corporation's current
assets would be at least equal to its current liabilities or 1.25 times its
current liabilities if the average pre-tax and pre-interest expense earnings for
the preceding two fiscal years were less than the average interest expense for
such years. Such tests are applied to California corporations on a consolidated
basis.

     Delaware law permits a corporation to declare and pay dividends out of
surplus or, if there is no surplus, out of net profits for the fiscal year in
which the dividend is declared and/or for the preceding fiscal year as long as
the amount of capital of the corporation following the declaration and payment
of the dividend is not less than the aggregate amount of the capital of the
corporation represented by the issued and outstanding stock of all classes
having a preference upon the distribution of assets. In addition, Delaware law
generally provides that a corporation may redeem or repurchase its shares only
if such redemption or repurchase would not impair the capital of the
corporation.

                                       89
<PAGE>
STOCKHOLDER VOTING

     Both California and Delaware law generally require that a majority of the
stockholders of both acquiring and target corporations approve statutory
mergers. Unless the corporation provides otherwise in its certificate of
incorporation, Delaware law does not require a stockholder vote of the surviving
company in a merger if:

     1. the merger agreement does not amend the existing certificate of
        incorporation;

     2. each share of the surviving company outstanding before the merger is an
        identical outstanding or treasury share after the merger; and

     3. the number of shares to be issued by the surviving company in the merger
        does not exceed 20% of the shares outstanding immediately prior to the
        merger.

     California law contains a similar exception to its voting requirements for
reorganizations where stockholders or the corporation itself, or both,
immediately prior to the reorganization will own immediately after the
reorganization equity securities constituting more than five-sixths of the
voting power of the surviving or acquiring corporation or its entity. Both
California and Delaware law also require that a sale of all or substantially all
of the assets of the corporation be approved by a majority of the voting shares
of the corporation transferring such assets. With exception, California law also
requires that mergers, reorganizations and similar transactions be approved by a
majority vote of each class of shares outstanding. In contrast, Delaware law
generally does not require class voting, except in transactions involving an
amendment to the certificate of incorporation which adversely affects a specific
class of shares. Should HealthCore authorize and issue shares of a new class of
capital stock, the holders of such shares would vote with the holders of the
HealthCore common stock on proposals not adversely affecting the HealthCore
common stock. In such event the holders of HealthCore common stock, if in the
minority, would be unable to control the outcome of a vote and, if in the
majority, would be able to control the outcome of such a vote.

     California law also requires that holders of non-redeemable common stock
receive non-redeemable common stock in a merger of the corporation with the
holders of more than 50% but less than 90% of such common stock or its affiliate
unless all of the holders of such common stock consent to the transaction. This
provision of California law may have the effect of making a "cash-out" merger by
a majority stockholder more difficult to accomplish. Although Delaware law does
not parallel California law in this respect, under some circumstances
Section 203 of the DGCL does provide similar protection against coercive
two-tiered bids for a corporation in which the stockholders are not treated
equally.

     California law also provides that, circumstances when a tender offer or a
proposal for a reorganization or for a sale of assets is made by an interested
party, which is generally a controlling or managing party of the target
corporation, an affirmative opinion in writing as to the fairness of the
consideration to be paid to the stockholders must be delivered to stockholders.
This fairness opinion requirement does not apply to a corporation which does not
have shares held of record by at least 100 persons, or to a transaction which
has been qualified under California state securities laws. Furthermore, if a
tender of shares or vote is sought pursuant to an interested party's proposal
and a later proposal is made by another party at least ten days prior to the
date of acceptance of the interested party proposal, the stockholders must be
informed of the later offer and be afforded a reasonable opportunity to withdraw
any vote, consent or proxy, or to withdraw any tendered shares. Delaware law has
no comparable provision, and the stockholders of Adatom might, therefore, be
deprived of an opportunity to consider such other proposal.

AMENDMENT OF BY-LAWS

     Under California law, by-laws may be amended by stockholders holding a
majority of the outstanding shares, or by the board, except that if the number
or a range of directors are specified in the by-laws, this provision can be
changed only with the approval of the stockholders. Stockholders can adopt or
amend by-law provisions to limit the ability of the board to amend the by-laws.
Under Delaware law, the by-laws may be amended only by the stockholders, unless
the corporation's certificate of incorporation confers the power to amend the
by-laws on the directors also. The certificate of incorporation of the surviving
company provides that the by-laws may be amended by the board of directors or
the holders of at least a majority of the outstanding stock.

                                       90
<PAGE>
AMENDMENT OF CERTIFICATE OR ARTICLES OF INCORPORATION

     Under both Delaware and California law, amendments to a corporation's
certificate or articles of incorporation must be approved by a corporation's
board of directors and by a majority of the stockholders. In addition, under
both Delaware and California law, if a corporation has more than one class or
series of stock outstanding, amendments that would affect the rights of such
class or series require the vote of a majority of the shares of such class or
series. "Supermajority" requirements, which are requirements of a vote of more
than a majority of the shares, are permitted under both California and Delaware
law. However, California law provides that, for a corporation with outstanding
shares held of record by 100 or more persons, such provision:

     1. cannot require a vote higher than 66 2/3%;

     2. must be approved by at least as large a proportion of the outstanding
        shares as the supermajority provision requires; and

     3. automatically expires after two years unless renewed pursuant to a
        stockholder vote.

     The proposed amended and restated certificate of incorporation of
HealthCore provides that it may be amended as provided in Delaware law.

INTERESTED DIRECTOR TRANSACTIONS

     Under both California and Delaware law, contracts or transactions in which
one or more of a corporation's directors has an interest are not void or
voidable because of such interest provided that conditions, such as obtaining
the required approval and fulfilling the requirements of good faith and full
disclosure, are met. With exceptions, the conditions are similar under
California and Delaware law. Under California and Delaware law:

     1. either the stockholders or the board of directors must approve any such
        contract or transaction after full disclosure of the material facts, and

     2. in the case of board approval, the contract or transaction must also be
        "just and reasonable" in California or "fair" in Delaware to the
        corporation; or

     3. the contract or transaction must have been just and reasonable or fair
        as to the corporation at the time it was approved.

     In the latter case, California law explicitly places the burden of proof on
the interested director. Under California law, if stockholder approval is
sought, the interested director is not entitled to vote his shares at a
stockholder meeting with respect to any action regarding such contract or
transaction. If board approval is sought, the contract or transaction must be
approved by a majority vote of a quorum of the directors, without counting the
vote of any interested directors, except that interested directors may be
counted for purposes of establishing a quorum. Under Delaware law, if board
approval is sought, the contract or transaction must be approved by a majority
of the disinterested directors, even though less than a majority of a quorum.

STOCKHOLDER DERIVATIVE SUITS

     California law provides that a stockholder bringing a derivative action on
behalf of a corporation have been a stockholder at the time of the transaction
in question, provided that appropriate tests are met. Under Delaware law, a
stockholder only may bring a derivative action on behalf of the corporation if
the stockholder was a stockholder of the corporation at the time of the
transaction in question or his or her stock thereafter devolved upon him or her
by operation of law. California law also provides that the corporation or the
defendant in a derivative suit may make a motion to the court for an order
requiring the plaintiff stockholder to furnish a security bond. Delaware does
not have a similar bonding requirement.

                                       91
<PAGE>
APPRAISAL RIGHTS

     Under both California and Delaware law, a stockholder of a corporation
participating in major corporate transactions may, under varying circumstances,
be entitled to appraisal rights pursuant to which such stockholder may receive
cash in the amount of the "fair value" (Delaware) or "fair market value"
(California) of his or her shares, as determined by a court, in lieu of the
consideration he or she would otherwise receive in the transaction. Under
Delaware law, such appraisal rights are not available:

     1. with respect to the sale, lease or exchange of all or substantially all
        of the assets of a corporation;

     2. with respect to a merger or consolidation by a corporation the shares of
        which either are listed on a national securities exchange or are held of
        record by more than 2,000 holders if such stockholders receive only
        shares of the surviving company or shares of any other corporation which
        either are listed on a national securities exchange or held of record by
        more than 2,000 holders, plus cash in lieu of fractional shares; or

     3. to stockholders of a corporation surviving a merger if no vote of the
        stockholders of the surviving company is required to approve the merger
        because the merger agreement does not amend the existing certificate of
        incorporation, each share of the surviving company outstanding prior to
        the merger is an identical outstanding or treasury share after the
        merger, and the number of shares to be issued in the merger does not
        exceed 20% of the shares of the surviving company outstanding
        immediately prior to the merger and if other conditions are met.

     The limitations on the availability of appraisal rights under California
law are different from those under Delaware law. Stockholders of a California
corporation whose shares are listed on a national securities exchange or on a
list of over-the-counter margin stocks issued by the Board of Governors of the
Federal Reserve System generally do not have such appraisal rights unless the
holders of at least 5% of the class of outstanding shares claim the right or the
corporation or any law restricts the transfer of such shares. California law
also generally affords appraisal rights in sale of asset reorganizations.
Appraisal rights are unavailable, however, if the stockholders of a corporation
or the corporation itself, or both, immediately prior to the reorganization will
own immediately after the reorganization equity securities constituting more
than five-sixths of the voting power of the surviving or acquiring corporation
or its parent entity.

DISSOLUTION

     Under California law, stockholders holding 50% or more of the total voting
power may authorize a corporation's dissolution, with or without the approval of
the corporation's board of directors, and this right may not be modified by the
articles of incorporation. Under Delaware law, unless the board of directors
approves the proposal to dissolve, in which case a simple majority may approve
the dissolution, the dissolution must be approved by stockholders holding 100%
of the total voting power of the corporation. In the event of such a
board-initiated dissolution, Delaware law allows a Delaware corporation to
include in its certificate of incorporation a supermajority voting requirement
in connection with dissolutions.

AUTHORIZED CAPITAL

     Adatom. The authorized capital stock of Adatom consists of
10,000,000 shares of Adatom common stock, of which there were 2,384,600 shares
outstanding as of the record date.

     HealthCore. The authorized capital stock of HealthCore prior to the merger
consisted of 19,640,000 shares of HealthCore class A common stock, of which
there were 3,183,000 shares outstanding as of the record date, 360,000 shares of
HealthCore class B common stock, of which there were 216,000 outstanding as of
the record date and 5,000,000 shares of HealthCore preferred stock, of which
there were no shares outstanding as of the record date. If the amendments to
HealthCore's Certificate of Incorporation are approved by the stockholders, the
authorized capital stock of HealthCore will be 50,000,000 shares of HealthCore
common stock and 5,000,000 shares of HealthCore preferred stock.

                          INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Stockholders
HealthCore Medical Solutions, Inc.
Grandview, Missouri

     We have audited the accompanying balance sheet of HealthCore Medical
Solutions, Inc. (the business successor to MegaVision, L.C.) as of
September 30, 1998 and the related statements of operations, changes in
stockholders' equity/(capital deficiency) and cash flows for the years ended
September 30, 1998 and 1997. These financial statements are the responsibility
of the Company's management. Our responsibility is to express an opinion on
these financial statements based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, the financial statements enumerated above present fairly,
in all material respects, the financial position of HealthCore Medical
Solutions, Inc. as of September 30, 1998 and the results of its operations and
its cash flows for the years ended September 30, 1998 and 1997, in conformity
with generally accepted accounting principles.

     As described more fully in Note A to the financial statements, the business
of the Company was conducted by MegaVision, L.C. prior to the merger in February
1997.

                               SEPTEMBER 30, 1998

NOTE A--THE COMPANY AND BASIS OF PRESENTATION

     HealthCore Medical Solutions, Inc. ("HealthCore" or the "Company") was
organized as a Delaware corporation in February 1997 and was in the development
stage through September 30, 1997. The year ended September 30, 1998 is the first
year during which it is considered an operating company. The Company markets and
administers health care service discount programs which are designed to enable
participants (members), who are enrolled through various organizations such as
insurance carriers, corporations, and unions to realize savings on purchases of
products and services. These savings will be obtained through a
company-organized network of providers, such as opticians, chiropractors,
optometrists, hearing specialists, pharmacists, dentists, physical therapists,
physicians and hospitals. The Company is the business successor to MegaVision,
L.C.

     In February 1997, MegaVision, L.C. ("MegaVision" or the "Predecessor"), a
Missouri limited liability company in the development stage, merged into
HealthCore, a newly formed entity. In conjunction with the merger, 1,100 member
units of MegaVision were exchanged for 708,000 shares of Class A common stock of
HealthCore and 600 member units of MegaVision were exchanged for 360,000 shares
of Class B common stock of HealthCore. The business of the Company was conducted
by MegaVision from June 1, 1995 to February 19, 1997. The merger described above
has been accounted for in a manner similar to a pooling of interests and, except
as otherwise indicated or where the context otherwise requires, the information
set forth in these financial statements has been adjusted to give retroactive
effect to the reorganization.

NOTE B--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  [1] CASH AND CASH EQUIVALENTS:

     Cash and cash equivalents include cash on hand, demand deposits and all
highly liquid investments with a maturity of three months or less at the time of
purchase. As of September 30, 1998, $4,007,700 was held in a money market mutual
fund.

  [2] PROPERTY AND EQUIPMENT:

     Property and equipment are recorded at cost. Depreciation and amortization
are being provided on the straight-line method over the estimated useful lives
of the assets. Equipment is depreciated over periods ranging from five to seven
years. Leasehold improvements are amortized over the shorter of the lease term
or their estimated useful life.

     Equipment under capital leases is recorded at the lesser of the present
value of the lease payments or fair value of the equipment. Such equipment is
amortized on a straight-line basis over the shorter of the lease term or its
estimated useful life.

  [3] MANAGEMENT ESTIMATES:

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

NOTE B--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)
  [4] REVENUE RECOGNITION:

     Membership revenues are recognized ratably over the life of the membership
for the period subsequent to the expiration of the money back guarantee, if any.

  [5] NET LOSS PER COMMON SHARE:

     In February 1997, the Financial Accounting Standards Board Issued Statement
of Financial Accounting Standards No. 128, "Earnings per Share" ("FAS 128")
which is effective for periods ended after December 15, 1997 and requires that,
upon adoption, all prior periods be restated. As a result of the adoption of FAS
128 and related interpretations the net loss per share for the year ended
September 30, 1997 increased by $3.29.

     Basic per common share data has been computed on the basis of the loss for
the period dividend by the weighted average shares outstanding during the period
excluding 900,000 shares placed in escrow (see Note H[1]). All warrants and
stock options which are potentially dilutive securities have been excluded from
the calculation since they would be anti-dilutive.

  [6] STOCK-BASED COMPENSATION:

     Statement of Financial Accounting Standards No. 123, "Accounting for
Stock-Based Compensation" ("FAS 123") allows companies to either expense the
estimated fair value of employee stock options or to continue to follow the
intrinsic value method set forth in Accounting Principles Board Opinion 25,
"Accounting for Stock Issued to Employees" ("APB 25") but disclose the pro forma
effects on net loss had the fair value of the options been expensed. The Company
has elected to apply APB 25 in accounting for its employee stock options
incentive plans.

     Property and equipment (at cost) as of September 30, 1998 consists of:

NOTE G--NOTES PAYABLE--BRIDGE UNITS

     In February and March 1997, the Company sold 46 Bridge Units, each
consisting of a $50,000, 10% subordinated note and warrants to purchase 25,000
shares of Class A common stock. The notes (aggregating $2.3 million principal
amount) were paid from the proceeds of the IPO in October 1997. Effective with
the IPO, the warrants were converted into IPO warrants. The Company received
$1,964,154, net of offering costs, in the Bridge Unit offering. One Bridge Unit
was purchased by the chairman of the board and his wife and one-half of one
Bridge Unit was purchased by a director, on the same terms as the other Bridge
Units.

     The Company valued the warrants at $310,500. Accordingly, additional
paid-in capital has been credited with $305,677 which represents the value of
the warrants less the allocable portion of the offering costs. The short-term
note has been discounted by the value of the warrants and the offering costs.
The discount has been amortized as additional interest expense from the date of
issuance to October 1997, when these notes were repaid.

                               SEPTEMBER 30, 1998

NOTE H--STOCKHOLDERS' EQUITY

  [1] INITIAL PUBLIC OFFERING:

     On October 17 1997, the Company, in its IPO, sold 1,760,000 units. Each
unit consists of one share of Class A common stock and one redeemable warrant to
purchase a share of Class A common stock at $6.50, expiring October 2002. On
November 10, 1997, the underwriter executed its option to sell an additional
264,000 shares of the Company's common stock. Proceeds from the IPO, net of
expenses of $1,745,000, approximated $8,355,000. In connection with the IPO, the
underwriter was granted an option to purchase up to 176,000 units at $6.00 per
unit and a director was granted a warrant to purchase 15,000 shares at $5.00 per
share.

     Upon consummation of the Company's initial public offering, certain
shareholders deposited 900,000 shares of common stock (the "Escrow Shares") into
an escrow account. Some or all of these shares are to be released upon the
Company meeting certain performance goals or the stock price exceeding certain
targets. If these goals are not met the shares will be canceled. However, should
the goals be met, the release of the shares owned by officers, directors and
consultants aggregating 432,000 shares of the 900,000 shares in escrow will
result in the Company recognizing an additional expense equal to the market
value of the shares released. A total of 400,000 shares of common stock held in
escrow are to be released if either (a) the Company's minimum pretax income, as
defined, equals or exceeds $3,800,000 for the year ending September 30, 1998,

equals or exceeds $12.50 per share for a 30 trading day period in the 18-month
period beginning with the consummation of the IPO or $16.50 per share for 30
trading days in the period beginning after 18 months after the consummation of
the IPO and ending 36 months after the IPO. All shares of common stock held in
escrow are to be released if either (a) the Company's minimum pretax income, as
defined, equals or exceeds $4,600,000 for the year ending September 30, 1998,
$6,600,000 for the year ending September 30, 1999 or $9,000,000 for the year
ending September 30, 2000 or (b) the average closing price of the common stock
equals or exceeds $15.00 per share for a 30 trading day period in the 18-month
period beginning with the consummation of the IPO or $18.00 per share for 30
trading days in the period beginning after 18 months after the consummation of
the IPO and ending 36 months after the IPO.

     As of September 30, 1998, the Company did not attain the income level nor
did the stock price meet or exceed the per share value necessary for the release
of the escrow shares.

  [2] ISSUANCE OF CLASS A COMMON STOCK:

     The Company had entered into a financing arrangement with DHF
International, Inc. ("DHF") which represented two short-term notes secured by
computer equipment owned by the Company. The notes, originally due
September 24, 1996 and February 28, 1997, were restructured in October 1996.
Under the restructuring agreement the collateral remained the same, however, the
Company was obligated to pay DHF $50,000. The payment terms were $20,000 on
December 1, 1996, and $10,000 on each of January 1, 1997, February 1, 1997 and
March 1, 1997. However, subsequently DHF canceled the Company's obligation to
pay and transferred all rights, title and interest in the computer equipment to
the Company, in exchange for 24,000 shares of the Company's Class A common stock
and a right of first refusal with respect to the leasing of equipment to the
Company.

     In February 1997, the Company issued an assignee of M.K.D. Capital Corp.
("M.K.D."), 132,000 shares of Class A common stock for total consideration of
$149,160. The shares were valued at their fair value at the date of issuance.
M.K.D. paid $3,850 in cash, and the remaining $145,310 has been charged to
operations for services rendered.

  [3] ISSUANCE OF CLASS B COMMON STOCK:

     In November 1996, the Company entered into an agreement to issue 216,000
shares of Class B common stock for $6,300 to the Chairman of the Board and Chief
Executive Officer. The Company valued these shares at $233,280, their estimated
fair value at the date of issuance, and charged $226,980 to operations as
compensation in the year ended September 30, 1997.

  [4] ISSUANCE OF WARRANTS:

     In September 1997, the Company granted warrants to purchase 284,000 shares
of Class A Common Stock to its Chairman of the Board and Chief Executive
Officer. The warrants are exercisable at $1.00 per share and expire in September
2007. The Company valued these warrants at $416,922, the estimated fair market
value of the warrants at the date of grant and incurred a noncash charge to
operations of $416,922. Warrants for 142,000 shares are immediately exercisable
and the remaining 142,000 will become exercisable upon the Company meeting
certain performance goals or the stock price exceeding certain targets. If these
targets are not met the warrants will be canceled. However, should the goals be
met, the Company will recognize an additional expense equal to the fair market
value of the portion of the warrants subject to such targets. The warrants will
become exercisable if either (a) the Company's minimum pretax income, as
defined, equals or exceeds $3,800,000 for the year ending September 30, 1998,
$5,500,000 for the year ending September 30, 1999 or $7,500,000 for the year
ending September 30, 2000 or (b) the average closing price of the common stock
equals or exceeds $12.50 per share for a 30 day trading period in the 18-month
period beginning with the consummation of the IPO or $16.50 per share for 30
trading days in the period beginning after 18 months after the consummation of
the IPO to 36 months after the IPO.

     As of September 30, 1998, the Company did not attain the income level nor
did the stock price meet or exceed the per share value necessary for the
remaining warrants to become exercisable.

  [5] STOCK OPTION PLAN:

     In 1997, the Company adopted a stock option plan under which 200,000 shares
of Class A common stock are reserved for issuance upon exercise of either
incentive or nonincentive stock options which may be granted from time to time
by the board of directors to employees and others. The options have a term of
10 years and outstanding options expire between May through June 2007.

     The fair value of each option granted has been estimated on the date of
grant using the Black-Scholes options pricing model with the following
assumptions; no dividend yield, expected volatility of 40%, risk-free interest
rates ranging from 6.00% and 6.75%, and expected lives of approximately
10 years. The weighted average fair value of options granted during 1998 and
1997 were $0.73 and $1.20 per share, respectively.

     The Company applies APB 25 in accounting for its stock option incentive
plan and, accordingly, recognizes compensation expense for the difference
between fair value of the underlying common stock and the exercise price of the
option at the date of grant. The effect of applying FAS 123 on 1998 and 1997 pro
forma net loss and net loss per common share is not necessarily representative
of the effect on reported net loss in future years due to, among other things
(1) the vesting period of the stock options and (2) the fair value of additional
stock options in future years. Had compensation cost for the Company's stock
option plan been determined based upon the fair value at the grant date for
awards under the plan consistent with the methodology prescribed under FAS 123,
the Company's proforma net loss for 1998 and 1997 would have been approximately
$(2,057,000) and $(3,311,000), respectively, and net loss per share would have
been approximately $(0.93) and $(12.32), respectively.

  [6] SHARES RESERVED FOR ISSUANCE:

     The Company has reserved 4,025,000 shares of its Class A common stock for
issuance upon exercise of the outstanding warrants and options, including
warrants issued in connection with the IPO.

  [7] COMMON AND PREFERRED STOCK:

     The shares authorized aggregate 19,784,000 shares of Class A common stock,
216,000 shares of Class B common stock and 5,000,000 shares of preferred stock
all with $.01 par value. The Class A and Class B shares of common stock are
substantially identical except that the Class A common stockholders have the
right to cast one vote per share and the Class B common stockholders have the
right to cast five votes per share. Class B shares automatically convert to
Class A shares on a one-for-one basis upon (i) the sale, gift or transfer,
(ii) death of the original stockholder, (iii) termination of employment of the
stockholder by the Company or (iv) if, for the year ended September 30, 1999,
the minimum pretax income, as defined, is less than $1,000,000 or if, for any
subsequent year through September 30, 2002, the Company's minimum pretax income
does not equal or exceed 110% of the prior year's minimum pretax income.

NOTE I--INCOME TAXES

     The Company, prior to March 1997, was a limited liability company and was
not subject to income taxes; however the Company's income or loss was required
to be recognized by the members and taxed on their individual income tax
returns. Accordingly, the losses incurred through February 1997 are not
available to offset the Company's future taxable income, if any.

     The Company's deferred tax asset as of September 30, 1998 represents a
benefit from net operating loss carryforwards of $1,504,500 which is reduced by
a valuation allowance of $1,504,500 since the future realization of such tax
benefit is not presently determinable.

                         NOTES TO FINANCIAL STATEMENTS
                                 JUNE 30, 1999

                                  (UNAUDITED)

NOTE A--THE COMPANY AND BASIS OF PRESENTATION

  GENERAL

     These financial statements have been prepared by HealthCore Medical
Solutions, Inc. ("HealthCore" or the "Company") in accordance with generally
accepted accounting principles for interim financial reporting and in accordance
with Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the
information and notes required by generally accepted accounting principles for
complete financial statements. In the opinion of management, the unaudited
financial statements include all adjustments (consisting only of normal
recurring adjustments) necessary to present fairly the financial position, the
results of operations and the statement of cash flows for the periods presented.

     The unaudited financial statements presented herein were prepared using the
underlying accounting principles utilized in the Company's September 30, 1998
audited financial statements filed on Form 10-KSB with the Securities and
Exchange Commission on December 29, 1998. Operating results for the nine months
ended June 30, 1999 are not necessarily indicative of the results that may be
expected for the year ending September 30, 1999.

     HealthCore was organized as a Delaware corporation in February 1997 as a
business successor to MegaVision, L.C. ("MegaVision"). The Company is an early
stage enterprise organized to develop, market and administer a health care
benefit services program which is designed to enable participants ("Members") to
obtain discounts on purchases of ancillary health care products and services
through certain networks ("Networks") of health care providers ("Providers").

     On July 1, 1999, HealthCore Medical Solutions, Inc., a Delaware corporation
("HealthCore"), and Adatom, Inc., a privately held California corporation
("Adatom"), entered into an Agreement and Plan of Merger (the "Merger
Agreement"), under which Adatom will be merged with and into HealthCore (the
"Merger"), with HealthCore being the surviving corporation under the name
Adatom.com, Inc. (the "Surviving Corporation"). All existing Class A common
stock and warrants of HealthCore will remain outstanding. The Class B common
stock of HealthCore will be eliminated and the Class A common stock of
HealthCore will be retitled as common stock. Adatom stockholders will receive
common stock of the Surviving Corporation representing approximately 77.5% of
the Surviving Corporation subject to adjustment in certain circumstances.
Consummation of the Merger is subject to a number of conditions including,
without limitation, approval of the Merger by the stockholders of HealthCore and
Adatom, and sale or liquidation of the healthcare discount benefits business
operated by HealthCore.

     To satisfy the condition to consummation of the Merger that HealthCore
liquidate or sell its discount healthcare business, on July 28, 1999 HealthCore
sold certain of its assets related to its discount healthcare business to
Randolph & Associates, Inc., a Texas corporation ("Randolph") and discontinued
the operation of its healthcare discount benefits business. The assets sold
included membership contracts, network access agreements, broker contracts, a
computer hardware lease, certain other miscellaneous contracts, furniture and
fixtures, software and trade names. Randolph agreed to assume performance of
HealthCore's obligations under the assigned contracts as of August 1, 1999. The
purchase price for the purchase of the assets was $4,090.64 in cash, the
assumption of a computer hardware lease for $45,909.36 and the assumption of
HealthCore's obligations under the other assigned contracts arising on or after

occupational therapy, chiropractic benefits, hospital and physician services and
retail consumer purchases throughout the United States. Members can access the
Networks through the use of discount membership cards. These discount membership
cards have been marketed, directly and through independent brokers, insurance
agents and consumer marketing organizations, to individuals and to employers,
health maintenance organizations and businesses and other associations who may
either purchase the cards for, or offer it to, their employees or members.

     In February 1997, MegaVision, L.C., a Missouri limited liability company in
the development stage, merged into HealthCore. In conjunction with the merger,
1,100 member units of MegaVision were exchanged for 708,000 shares of Class A
common stock of HealthCore and 600 member units of MegaVision were exchanged for
360,000 shares of Class B common stock of HealthCore. The business of the
Company was conducted by MegaVision from June 1, 1995 to February 19, 1997. The
merger described above has been accounted for in a manner similar to a pooling
of interests and, except as otherwise indicated or where the context otherwise
requires, the information set forth in these financial statements has been
adjusted to give retroactive effect to the reorganization.

     HealthCore and MegaVision have been principally devoted to organizational
activities, raising capital, marketing, building a sales network and negotiating
provider agreements.

NOTE B--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  [1] CASH AND CASH EQUIVALENTS:

     Cash and cash equivalents include cash on hand, demand deposits and all
highly liquid investments with a maturity of three months or less at the time of
purchase.

  [2] MANAGEMENT ESTIMATES:

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

  [3] REVENUE AND COST OF SALES RECOGNITION:

     All monthly and single annual payment sales and their corresponding
expenses, including the costs of issuance of HealthCare Solutions Cards, sales
commissions, provider fees and a provision for cancellations from potential
guarantee-related refunds incurred by the Company at the time of sale, are
recognized in the monthly period after the expiration of the guarantee period
which the card sale is billed. Annual card sales are recognized ratably over the
term of the membership. The Company currently offers a full money-back guarantee
to Members who are not satisfied with the HealthCare Solutions Card.

  [4] PROPERTY AND EQUIPMENT:

     Property and equipment are recorded at cost. Depreciation and amortization
are being provided on the straight-line method over the estimated useful lives
of the assets. Equipment is depreciated over periods ranging from five to seven
years. Leasehold improvements are amortized over the shorter of the lease term
or their estimated useful life.

                                  (UNAUDITED)

NOTE B--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)

     Equipment under capital leases is recorded at the lesser of the present
value of the lease payments or fair value of the equipment. Such equipment is
amortized on a straight-line basis over the shorter of the lease term or its
estimated useful life.

  [5] NET LOSS PER SHARE:

     Net loss per share was computed based upon the weighted average number of
shares of common stock outstanding during each year presented, excluding the
900,000 shares placed in escrow. Upon the Company exceeding certain income
levels or the common stock exceeding certain market prices per share, some or
all of the common shares held in escrow are to be released (see Note F).

NOTE C--NOTES PAYABLE--BRIDGE UNITS

     In February and March 1997, the Company sold 46 Bridge Units, each
consisting of (i) a $50,000 10% subordinated note and (ii) warrants to purchase
25,000 shares of Class A common stock. The notes, aggregating $2.3 million in
principal amount and $142,979 in accrued interest, were repaid on October 17,
1997 from the proceeds of the Company's initial public offering ("IPO").
Concurrently with the IPO, the warrants were converted into IPO warrants. The
Company received $1,964,154, net of offering costs, in the Bridge Unit offering.
One Bridge Unit was purchased by the Chairman of the Board and his wife and
one-half of one Bridge Unit was purchased by a director, on the same terms as
the other Bridge Units.

     The Company valued the warrants at $310,500. Accordingly, additional
paid-in capital has been credited with $305,677 which represents the value of
the warrants less the allocable portion of the offering costs. The short-term
notes were discounted by the value of the warrants and the offering costs. The
discount was amortized as additional interest expense from the date of issuance
to October 17, 1997, when these notes were repaid.

NOTE D--CAPITAL STOCK

  [1] STOCK OPTION PLAN:

     In February 1997, the Company adopted a stock option plan under which
200,000 shares of Class A common stock are reserved for issuance upon exercise
of either incentive or non-incentive stock options which may be granted from
time to time by the board of directors to officers, directors, employees and
others. The Company has granted options to purchase 172,500 shares of Class A
common stock at prices ranging from $.875 per share to $5.00 per share. Of the
options granted, 15,000 have been forfeited by resignation of the grantees and
are available for future grants. The remaining 157,500 options granted and
outstanding will fully vest during the period from August 1997 through June 2001
and will expire ten years from the date of grant.

  [2] SHARES RESERVED FOR ISSUANCE:

     The Company has reserved 3,849,000 shares of its Class A common stock for
issuance upon exercise of the outstanding warrants and options, including
warrants issued in connection with the IPO.

  [3] COMMON AND PREFERRED STOCK:

     The shares authorized aggregate 19,784,000 shares of Class A common stock,
216,000 shares of Class B common stock and 5,000,000 shares of preferred stock,
all with $.01 par value. The Class A and Class B shares of common stock are
substantially identical except that the Class A common stockholders have the
right to cast one vote per share and the Class B common stockholder has the
right to cast five votes per share. Class B shares

automatically convert to Class A shares on a one-for-one basis upon (i) the
sale, gift or transfer, (ii) death of the original stockholder thereof,
(iii) termination of employment of the stockholder by the Company for any reason
or (iv) if, for the year ended September 30, 1999, the minimum pretax income, as
defined, is less than $1,000,000 or if, for any subsequent year through
September 30, 2002, the Company's minimum pretax income does not equal or exceed
110% of the prior year's minimum pretax income.

     Prior to the execution of a non-binding letter of intent on April 27, 1999,
relative to the Adatom, Inc. merger the Company employed Polan under an
employment agreement (the "Employment Agreement") expiring on November 30, 2000,
providing for an annual base salary of two hundred thousand ($200,000) dollars,
together with other compensation and benefits. The Employment Agreement made no
provision for the termination thereof without cause. In furtherance of the
transaction contemplated by the letter, by letter amendment dated April 27,
1999, the Employment Agreement was amended to provide the Company with the right
to terminate the Employment Agreement at any time, without cause, upon the
expiration of one hundred twenty (120) days following the date of the execution
of the letter amendment, whereupon the Company will pay to Polan the lesser of
(a) one hundred fifty thousand ($150,000) dollars, or (b) sixty (60%) percent of
the present value of the remaining compensation and benefits due under the terms
of the employment agreement on the date of its termination. In consideration for
the amendment, the Company issued Polan 165,000 shares of Class A Common Stock
of the Company.

     On April 27, 1999, the Company engaged Jesup & Lamont as exclusive
financial adviser to the Company in connection with the Merger, and as the
Company's exclusive placement agent with respect to a contemplated private
placement (the "Placement") of approximately six million ($6,000,000) dollars in
equity securities of the Company following the consummation of the Merger, the
Company, pursuant to the terms of an engagement letter (the "Engagement Letter")
among the Company, Adatom, and Jesup & Lamont. As partial consideration for such
services, the Company has agreed to issue to Jesup & Lamont (a) upon the signing
of the Engagement Letter, five-year warrants to purchase two hundred thousand
(200,000) shares of the Class A Common Stock of the Company at an exercise price
of one ($1.00) per share (one hundred thousand (100,000), of which vested upon
the execution of the Engagement Letter, and the remaining one hundred thousand
(100,000) to vest only upon the closing of the Merger), and (b) five-year
warrants to purchase up to ten (10%) percent of the securities sold in the
Placement at an exercise price equal to the price at which the securities are
sold in the Placement.

NOTE E--INCOME TAXES

     The Company's deferred tax asset as of September 30, 1998 represented a
benefit from net operating loss carryforward of $1,504,500. This deferred tax
asset has been reduced by a valuation allowance of $1,504,500 since the future
realization of such tax benefit is not presently determinable. As of
September 30, 1998, the Company had a net operating loss carryforward of
approximately $3,946,000 expiring in 2012 and 2018. As a result of the IPO,
usage of approximately $2,000,000 of this net operating loss carryforward is
limited to approximately $789,000 per year.

NOTE F--INITIAL PUBLIC OFFERING

     On October 17 1997, the Company, in its IPO, sold 1,760,000 units. Each
unit consists of one share of Class A common stock and one redeemable warrant to
purchase a share of Class A common stock at $6.50, expiring October 2002. On
November 10, 1997, the underwriter executed its option to sell an additional
264,000 shares of the Company's common stock. Proceeds from the IPO, net of
expenses of $1,745,000, approximated $8,355,000. In connection with the IPO, the
underwriter was granted an option to purchase up to 176,000 units at $6.00 per
unit and a director was granted a warrant to purchase 15,000 shares at $5.00 per
share.

NOTE F--INITIAL PUBLIC OFFERING--(CONTINUED)

     Upon consummation of the Company's initial public offering, certain
shareholders deposited 900,000 shares of common stock (the "Escrow Shares") into
an escrow account. Some or all of these shares are to be released upon the
Company meeting certain performance goals or the stock price exceeding certain
targets. If these goals are not met the shares will be canceled However, should
the goals be met, the release of the shares owned by officers, directors and
consultants aggregating 432,000 shares of the 900,000 shares in escrow will
result in the Company recognizing an additional expense equal to the market
value of the shares released. A total of 400,000 shares of common stock held in
escrow are to be released if either (a) the Company's minimum pretax income, as
defined, equals or exceeds $3,800,000 for the year ending September 30, 1998,
$5,500,000 for the year ending September 30, 1999 or $7,500,000 for the year
ending September 30, 2000 or (b) the average closing price of the common stock
equals or exceeds $12.50 per share for a 30 trading day period in the 18-month
period beginning with the consummation of the IPO or $16.50 per share for 30
trading days in the period beginning after 18 months after the consummation of
the IPO and ending 36 months after the IPO. All shares of common stock held in
escrow are to be released if either (a) the Company's minimum pretax income, as
defined, equals or exceeds $4,600,000 for the year ending September 30, 1998,
$6,600,000 for the year ending September 30, 1999 or $9,000,000 for the year
ending September 30, 2000 or (b) the average closing price of the common stock
equals or exceeds $15.00 per share for a 30 trading day period in the 18-month
period beginning with the consummation of the IPO or $18.00 per share for 30
trading days in the period beginning after 18 months after the consummation of
the IPO and ending 36 months after the IPO.

     As of June 30, 1999, the Company did not attain the income level nor did
the stock price meet or exceed the per share value necessary for the release of
the escrow shares.

NOTE G--NOTE RECEIVABLE FROM ADATOM, INC.:

     On April 28, 1999 a note in the value of $250,000 was executed with Adatom,
Inc. The note is payable on demand 90 days after the termination of the merger

                          INDEPENDENT AUDITORS' REPORT

Board of Directors
Adatom, Inc.
Milpitas, CA

We have audited the accompanying balance sheet of Adatom, Inc. (a California
corporation in the development stage), as of December 31, 1998 and 1997, and the
related statements of operations, stockholders' equity, and cash flows for the
years then ended and for the period from inception to December 31, 1998. These
financial statements are the responsibility of the management of Adatom, Inc.
Our responsibility is to express an opinion on these financial statements based
on our audit.

We conducted our audit in accordance with generally accepted audited standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Adatom, Inc. as of
December 31, 1998 and 1997, and the results of its operations and its cash flows
for the years then ended and for the period from inception to December 31, 1998,
in conformity with generally accepted accounting principles.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 8 to the
financial statements, the Company has suffered recurring losses from operations
and has a net capital deficiency that raise substantial doubt about its ability
to continue as a going concern. Management's plans in regard to these matters
are also described in Note 8. The financial statements do not include any
adjustments that might result from the outcome of this uncertainty.

                         NOTES TO FINANCIAL STATEMENTS

                               DECEMBER 31, 1998

NOTE 1--ORGANIZATION AND OPERATIONS

     Adatom, Inc. (the "Company") is a development stage enterprise founded
October 1996 for the purpose of developing and marketing an electronic product
distribution system using proprietary computer technologies. Using the Company's
technology, consumers may place orders through an agent, directly on an internet
site, or with a Company salesperson. The orders so placed are typically routed
directly to the manufacturer so that the goods may be delivered directly to the
consumer.

     The future success of the Company is dependent upon several factors
including its ability to continue to expand and enhance its array of available
products and to attract and retain qualified agents and salespersons. To date
substantially all capital has been obtained from the Company's majority
shareholder.

NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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

     Inventory--Inventory consists of consumer goods available for sale and is
stated at the lower of first-in, first-out cost or market.

     Fixed assets--Fixed assets are stated at cost and are being depreciated
over their estimated useful lives using the straight-line method. Various
accelerated methods are used for computing depreciation for income tax purposes.
At December 31, 1998 and 1997, fixed assets consisted of:

</TABLE>

     Intangible assets--Organization costs are being amortized over five years
using the straight-line method. At December 31, 1998 accumulated amortization
totals approximately $4,800.

     Software development costs--The Company classifies the costs of planning
and developing software products as research and development and charges those
costs to expense when incurred.

     During 1998, the Company received approximately $130,000 as a contract
reimbursement for part of its software development activities. This
reimbursement is included with research and development expenses in the
accompanying statement of operations.

     Income taxes--The Company is taxed under the provisions of Subchapter S of
the Internal Revenue Code. Under those provisions, the Company pays no Federal
income taxes but is taxed at the state level using the statutory rates in effect
for S-Corporations. Additionally, the stockholders are individually taxed on
their proportionate share of the Company's taxable income.

     Advertising costs--Advertising costs include the costs of brochures, print
advertisements and radio commercials, and are expensed when incurred. During the
years ended December 31, 1998 and 1997 and for the period from inception to
December 31, 1998, advertising costs of approximately $153,000, $15,000 and
$180,000, respectively, were charged to expense.

NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)

     Reclassification--Certain 1997 balances have been reclassified to conform
to the 1998 financial statement presentation. These reclassifications have no
effect on previously reported net income.

NOTE 3--NOTES RECEIVABLE FROM FRANCHISEES

     During 1997, the Company entered into seven franchise and agency agreements
for which it had recognized $124,000 in initial franchise fees. Of this amount,
$105,000 had been financed by the Company under unsecured notes receivable.
During 1998, the Company modified its business strategy toward one more oriented
to internet-based commerce. Accordingly, the Company offered to cancel the
franchise agreements and to forgive the balance of the franchisees' indebtedness
to the Company. Six of the Company's franchisees elected to terminate their
agreements resulting in a charge to income of approximately $79,000,
representing the write off of the remaining balances due from these franchisees.
The remaining note is due in equal monthly installments of approximately $310,
including interest at 9% per annum, and matures September 2002.

NOTE 4--LINE OF CREDIT

     The Company has a line of credit agreement, expiring in December 2001, with
Wells Fargo Bank. Borrowings under the agreement are secured by the Company's
certificate of deposit at the same bank, bear interest at the bank's index rate
plus 1% (8.75% at December 31, 1998), and are limited to $50,000. At
December 31, 1998, $45,873 is outstanding under this agreement and is included
with long-term notes and lease contracts payable in the accompanying balance
sheets.

NOTE 5--NOTE PAYABLE TO SHAREHOLDER

     This note is unsecured, bears interest at 7% per year, and is due
January 1, 2000.

NOTE 6--INCOME TAXES

     At December 31, 1998 and 1997, net deferred taxes include the following:

</TABLE>

     The book basis of property and equipment exceeds its tax basis by the
cumulative amount that accelerated depreciation exceeds straight-line
depreciation. The excess will be taxable in future periods through decreased
depreciation deductions. Certain expenses recognized currently for financial
reporting purposes are not deductible for income tax purposes until paid in
future periods.

     At December 31, 1998, the Company has approximately $1,870,000 in net
operating loss carryforwards, expiring in 2004, available to offset future state
taxable income. The deferred tax asset related to these operating loss
carryforwards has been fully reserved.

                               DECEMBER 31, 1998

NOTE 7--COMMITMENTS

     The Company leases its facilities under operating lease agreements,
expiring in May 2000, which currently require monthly payments totaling
approximately $7,800. Rent expense paid under these leases for the years ended
December 31, 1998 and 1997 and for the period from inception to December 31,
1998, was approximately $87,000, $44,000 and $137,000, respectively.

NOTE 8--GOING CONCERN

     As shown in the accompanying financial statements, the Company incurred a
net loss of approximately $1,200,000 during the year ended December 31, 1998,
and, as of that date, the Company's total liabilities exceeded its total assets
by approximately $1,600,000. Those factors create an uncertainty about the
Company's ability to continue as a going concern. Management's plans to generate
profitable operations include creation of joint marketing programs with
identified consumer and business product wholesalers and distributors, and the
selective licensing of its proprietary technology to producers, wholesalers and
distributors. The ability of the Company to continue as a going concern is
dependent on the success of future operations and the continued financial
support of its majority stockholder. The accompanying financial statements do
not include any adjustments that might be necessary if the Company is unable to
continue as a going concern.

                         NOTES TO FINANCIAL STATEMENTS

                                  (UNAUDITED)

NOTE 1--ORGANIZATION AND OPERATIONS:

     Adatom, Inc. (the "Company") is a development stage enterprise founded in
October 1996 for the purpose of developing and marketing an electronic product
distribution system using proprietary computer technologies. Using the Company's
technology, consumers may place orders through an agent, directly on an Internet
site, or with a Company salesperson. The orders so placed are typically routed
directly to the manufacturer so that the goods may be delivered directly to the
consumer.

     The future success of the Company is dependent upon several factors
including its ability to continue to expand and enhance its array of available
products and to attract and retain qualified agents and salespersons. To date,
substantially all capital has been obtained from the Company's majority
shareholder.

NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

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

     Inventory--Inventory consists of consumer goods available for sale and is
stated at the lower of first-in, first-out cost or market.

     Fixed assets--Fixed assets are stated at cost and are being depreciated
over their estimated useful lives using the straight-line method. Various
accelerated methods are used for computing depreciation for income tax purposes.
At June 30, 1999 and June 30, 1998, fixed assets consisted of:

</TABLE>

     Intangible assets--Organization costs are being amortized over five years
using the straight-line method. At June 30, 1999 accumulated amortization totals
approximately $5,900.

     Software development costs--The Company classifies the costs of planning
and developing software products as research and development and charges those
costs to expense when incurred.

     During the six months ended June 30, 1998, the Company received
approximately $112,000 as a contract reimbursement for part of its software
development activities. This reimbursement is included with research and
development expenses in the accompanying statement of operations.

     Income taxes--The Company is taxed under the provisions of Subchapter S of
the Internal Revenue Code. Under those provisions, the Company pays no Federal
income taxes but is taxed at the state level using the statutory rates in effect
for S-Corporations. Additionally, the stockholders are individually taxed on
their proportionate share of the Company's taxable income.

     Advertising costs--Advertising costs include the costs of brochures, print
advertisements and radio commercials, and are expensed when incurred. During the
six months ended June 30, 1999, and 1998 and the

period from inception to June 30, 1999, advertising costs of approximately
$138,000, $42,000 and $318,000, respectively, were charged to expense.

NOTE 3--NOTES RECEIVABLE FROM FRANCHISEES:

     At June 30, 1999, the Company held a note receivable from one franchisee.
This note is due in equal monthly installments of approximately $310, including
interest at 9% per annum, and matures September 2002. In December 1998, the
Company ceased its franchising operations and offered to cancel the notes
receivable from its existing franchisees. Six of the Company's franchisees
accepted this offer, resulting in the cancellation of $78,921 of notes
receivable and a charge to income of $78,921.

NOTE 4--NOTES PAYABLE:

     The $1,800,000 note payable to shareholder is unsecured, non-interest
bearing, and is due July 1, 2000. Additionally, Adatom has a $250,000 note
payable to HealthCore Medical Solutions, Inc., the company with which Adatom
plans to merge (see Note 8). This note is secured by Adatom's assets, is
non-interest bearing, and is due upon closing of the merger transaction
discussed at Note 8 or within 90 days of the termination of the related letter
of intent to merge.

NOTE 5--INCOME TAXES:

     At June 30, 1999 and June 30, 1998, net deferred taxes consist of the
following:

</TABLE>

     The book basis of property and equipment exceeds its tax basis by the
cumulative amount that accelerated depreciation exceeds straight-line
depreciation. The excess will be taxable in future periods through decreased
depreciation deductions. Certain expenses recognized currently for financial
reporting purposes are not deductible for income tax purposes until paid in
future periods.

     At June 30, 1999, the Company has approximately $2,700,000 in net operating
loss carryforwards, expiring in 2004, available to offset future state taxable
income. The deferred tax asset related to these operating loss carryforwards has
been fully reserved.

NOTE 6--COMMITMENTS:

     The Company leases its facilities under operating lease agreements,
expiring in May 2000, which currently require monthly payments totaling
approximately $7,800. Rent expense paid under these leases for the six months
ended June 30, 1999 and 1998 and for the period from inception to June 30, 1999,
was approximately $49,000, $45,000 and $186,000, respectively.

NOTE 7--GOING CONCERN:

     As shown in the accompanying financial statements, the Company incurred a
net loss of approximately $880,000 for the six months ended June 30, 1999 and
has incurred an aggregate loss of $2,820,790 since its inception. At June 30,
1999, the Company's total liabilities exceeded its total assets by approximately
$2,500,000. Those factors create an uncertainty about the Company's ability to
continue as a going concern. Management's plans to generate profitable
operations principally involve the development and establishment of its Internet
commerce website. The ability of the Company to continue as a going concern is
dependent on the success of future operations and the continued financial
support of its majority stockholder. The accompanying financial statements do
not include any adjustments that might be necessary if the Company is unable to
continue as a going concern.

NOTE 8--SUBSEQUENT EVENTS:

     The Company has filed a proxy with the Securities and Exchange Commission
dated August 11, 1999. The proxy provides for the merger of the Company with and
into HealthCore Medical Solutions, Inc. pursuant to the Agreement and Plan of
Merger among the Company and HealthCore dated as of July 1, 1999. The combined
company will be named Adatom.com, Inc. and will operate Adatom's existing
business of an Internet retailer. In the merger, Adatom's stockholders will
receive approximately 2.17 shares of HealthCore common stock, subject to
adjustment, as defined in the agreement.

in accordance with the applicable provisions of the DGCL and the CGCL, and shall
make all other filings or recordings as may be required under the DGCL and the

Merger is duly filed with the Secretary of State of the States of Delaware and
California (the "Effective Time").

     1.4 Certificate of Incorporation and By-laws.  The Certificate of
Incorporation of HealthCore shall be the Certificate of Incorporation of the
Surviving Corporation until thereafter changed or amended as provided herein or

on the Board of Directors of the Surviving Corporation shall be increased to

                                   ARTICLE II
                       EFFECT OF MERGER ON CAPITAL STOCK

     2.1 Effect on Adatom Capital Stock, Options and Warrants.  At the Effective
Time, by virtue of the Merger and without any action on the part of the holder
thereof:

          (a) Conversion of Shares of Adatom Common Stock.  Each issued and
     outstanding share of Adatom common stock, no par value per share (the
     "Adatom Common Stock") shall be converted into the right to receive the Per
     Share Merger Consideration (as hereinafter defined), subject, however, to
     the execution by each of the holders (other than Polan) of the shares of
     Adatom Common Stock of a lock-up agreement in form and substance reasonably
     satisfactory to Adatom (the "Adatom Lock-up Agreement") covering the shares
     received by such Adatom shareholders in respect of the Per Share Merger
     Consideration (collectively, the "Adatom Newly Issued Shares"), other than
     the Polan Adatom Shares (as hereinafter defined), which shall be subject to
     a lock-up period pursuant to the terms of the HealthCore Lock-up Agreements
     (as hereinafter defined). The Adatom Lock-Up Agreement shall provide, among
     other things, that the Adatom Newly Issued Shares shall be subject to a six
     (6) month lock-up, prohibiting the sale, assignment or transfer thereof
     during such six (6) month period. The holders of certificates representing
     shares of Adatom Common Stock (each a "Certificate", and collectively, the
     "Certificates") shall cease to have any rights with respect to such shares
     except the right to receive the applicable Per Share Merger Consideration,
     without interest, upon surrender of the Certificate in accordance with
     Article IV hereof.

          (b) Treasury Shares.  Each share of Adatom Common Stock, if any, held
     in the treasury by Adatom shall be canceled and retired and cease to exist,
     without any conversion thereof.

          (c) Adatom Options and Warrants.  Each issued and outstanding option
     (each an "Adatom Option") and warrant (each an "Adatom Warrant")
     exercisable for shares of Adatom Common Stock shall be converted into an
     option or warrant, as applicable, exercisable for shares of HealthCore
     Common Stock, $.01 par value per share (the "HealthCore Common Stock") with
     the same terms and conditions as the Adatom Option or the Adatom Warrant,
     as the case may be, except that the exercise price and the number of shares
     of HealthCore Common Stock issuable upon exercise of such options and
     warrants shall be divided and multiplied, respectively, by the Per Share
     Merger Consideration.

     2.2 Effect on Capital Stock of HealthCore.  At the Effective Time (a) each
issued and outstanding share of HealthCore Class A Common Stock, par value $.01
per share (the "HealthCore Common Stock"), and each option and warrant
exercisable for shares of HealthCore Common Stock, shall remain outstanding with
the same rights, terms and conditions attendant thereto immediately prior to the
Effective Time; provided that such HealthCore Class A Common Stock shall be
reclassified as "Common Stock" in accordance with the provisions of Section 1.4
hereof; and (b) each issued and outstanding share of HealthCore Class B Common
Stock, par value $.01 (the "HealthCore Class B Common Stock") shall be converted
into one (1) share of HealthCore Common Stock. Notwithstanding anything
contained herein to the contrary, if a Certificate is held by a Dissenting
Shareholder (as hereinafter defined), such Dissenting Shareholder shall have the
rights with respect thereto as set forth in Section 4.4 hereof and as provided
by applicable law.

                                  ARTICLE III
                 CALCULATION OF PER SHARE MERGER CONSIDERATION;
                    ADJUSTED PER SHARE MERGER CONSIDERATION

     3.1 Calculation of Per Share Merger Consideration.

          (a) Base Calculation.  The "Per Share Merger Consideration" shall be
     defined as that number of shares of HealthCore Common Stock equal to
     (i) the difference between (A) (1) the Outstanding HealthCore Common Stock
     (as hereinafter defined), divided by (2) .225, and (B) the Outstanding
     HealthCore Common Stock, divided by (ii) the Outstanding Adatom Common
     Stock (as hereinafter defined), subject to adjustment as hereinafter set
     forth (the total number of shares of HealthCore Common Stock issuable
     hereunder, the "Merger Consideration").

          (b) Adatom Common Stock Outstanding.  For purposes of calculating the
     Per Share Merger Consideration, the "Outstanding Adatom Common Stock" shall
     be defined as the total number of shares of Adatom Common Stock outstanding
     immediately prior to the Closing which shall be deemed to include (i) all
     outstanding shares of Adatom Common Stock (including, without limitation,
     the shares of Adatom Common Stock issuable to Polan as described in
     Section 6.1(c) hereof), and (ii) all shares of Adatom Common Stock
     underlying (A) the options and warrants to purchase such shares of Adatom
     Common Stock, (B) the shares of Adatom Common Stock into which the
     convertible bridge notes (the "Convertible Notes") placed by Jesup & Lamont
     Securities Corporation ("Jesup & Lamont") are convertible prior to or
     simultaneously with the Closing, and the shares issuable upon exercise of
     warrants to purchase the Adatom Common Stock issued by Adatom to Jesup &
     Lamont as compensation under the terms of the Adatom Engagement Letter (as
     hereinafter defined), and (C) shares of Adatom Common Stock issued or
     issuable to the Brokers (as defined in Section 5.1(u) hereof).

          (c) HealthCore Common Stock Outstanding.  For purposes of calculating
     the Per Share Merger Consideration, the "Outstanding HealthCore Common
     Stock" shall be defined as the total number of shares of HealthCore Common
     Stock outstanding immediately prior to the Closing which shall be deemed to
     include (i) all outstanding shares of HealthCore Common Stock (other than,
     and specifically excluding, eighty (80) percent of the shares of HealthCore
     Common Stock owned by the Escrow Shareholders who have executed and
     delivered to HealthCore, as of the Closing Date, the Termination
     Agreements, and which are held in escrow pursuant to the terms of the
     Escrow Agreement, as such capitalized terms are defined in Section 6.5
     hereof), and (ii) all shares of HealthCore Common Stock underlying (A) the
     options and warrants to purchase such shares of Class A Common Stock with
     an exercise price of $1.25 or less, other than the warrants issued to Jesup
     & Lamont as compensation pursuant to the terms of that certain engagement
     letter (the "HealthCore Engagement Letter"), dated April 27, 1999, between
     HealthCore and Jesup & Lamont, a copy of which is attached hereto as
     Exhibit A, and other than, and specifically excluding, eighty (80) percent
     of the shares of HealthCore Common Stock underlying that certain warrant to
     purchase 142,000 shares of HealthCore Common Stock held by Polan, provided
     Polan shall have executed and delivered to HealthCore, as of the Closing
     Date, an agreement in substantially the form of the Termination Agreements,
     and (B) the options or warrants issued on or after the date hereof in
     consideration for the settlement of certain obligations of HealthCore to
     employees and third party creditors of HealthCore in accordance with the
     provisions of Section 6.2(d) hereof.

     3.2 Adjustment to Per Share Merger Consideration.  The Per Share Merger
Consideration shall be subject to adjustment as follows:

          (a) Closing Cash Amount.  In the event the cash assets of HealthCore
     immediately prior to the Closing (the "Closing Cash Amount") are less than
     Two Million Eight Hundred Fifty Thousand ($2,850,000) Dollars, then the
     number of shares of HealthCore Common Stock issued to the holders of record
     on the Closing Date of Outstanding Adatom Common Stock other than Polan
     (the "Adatom Former Shareholders") shall be increased as follows: first,
     subtract from twenty-two and one-half (22.5%) percent (the "HealthCore Post
     Merger Percentage") the product of the difference between (i) $2,850,000
     and (2) the Closing Cash Amount, multiplied by .00000309 (such difference
     being the "New HPMP"); second, calculate the percentage obtained by
     dividing the HealthCore Post Merger Percentage by the New HPMP and
     subtracting one hundred (100%) percent (the difference being the "Margin
     Percentage"); and third,

                                      A-4
<PAGE>
     multiply the Margin Percentage by the number of shares of HealthCore Common
     Stock which would have been outstanding immediately after the Merger
     pursuant to Section 3.1 (such product being the "Increased Shares"). For
     purposes of calculating the new Per Share Merger Consideration, divide the
     number of Increased Shares by the Outstanding Adatom Common Stock, and add
     that number to the Per Share Merger Consideration. At the time of the
     Merger, and without necessity of any further action, Polan shall transfer
     and shall be deemed to have transferred to the Adatom Former Shareholders,
     on a pro rata basis, the number of shares of HealthCore Common Stock that
     he would have received as his pro rata percentage of the Increased Shares
     had he been included in the adjustment to the Per Share Merger
     Consideration described above. Polan shall have no ownership interest of
     any kind in such shares at any time, but shall hold them in trust for the
     other holders of Outstanding Adatom Common Stock. For the purposes of this
     section the Closing Cash Amount shall be deemed to include (i) all cash on
     hand, (ii) the aggregate consideration payable to HealthCore upon the
     exercise of all outstanding options and warrants of HealthCore as of the
     date hereof having an exercise price not greater than $1.25 per share;
     (iii) the aggregate consideration payable to HealthCore for the purchase of
     shares of HealthCore Common Stock upon the exercise of options and warrants
     to purchase the same, up to an aggregate maximum of Thirty Thousand
     (30,000) shares, issued on or after the date hereof in consideration for
     the settlement of certain obligations of HealthCore to employees and third
     party creditors of HealthCore, provided that only $1.25 shall be includable
     in the Closing Cash Amount for options and warrants with an exercise price
     in excess of $1.25, (iv) the aggregate amount of prepaid expenses paid by
     HealthCore for the benefit of the Surviving Corporation, (v) the principal
     amount loaned by HealthCore to Adatom for bridge financing as evidenced by
     that certain Promissory Note (the "Note"), dated April 27, 1999, executed
     by Adatom in favor of HealthCore, (vi) the aggregate amount of any cash
     payments made to Polan pursuant to the terms of Paragraph 4(c) of that
     certain Employment Agreement, dated September 30, 1998, between HealthCore
     and Polan, as amended, (vii) the aggregate sum of any and all reasonable
     Transaction Expenses (as defined in Section 10.5 hereof) paid by HealthCore
     through the Closing Date; provided, however, that Adatom shall have
     approved of any Transaction Expense (other than legal, accounting and
     investment banker fees and expenses, provided that the fees payable in
     connection with the preparation of a fairness opinion shall be commensurate
     with the fair market value for such services) incurred and paid by
     HealthCore following the execution hereof, which, individually, is in
     excess of Twenty-Five Thousand ($25,000) Dollars; and (viii) the aggregate
     sum of any deferred payments to be received by HealthCore within one
     hundred twenty (120) days following the Closing in connection with the sale
     of the HealthCore Business (as hereinafter defined). The Closing Cash
     Amount shall be reduced by the liquidated sum of the accrued but unpaid
     liabilities of HealthCore on the Closing Date other than, and specifically
     excluding, (i) any and all reasonable Transaction Expenses incurred by
     HealthCore prior to the Closing Date, and (ii) any liabilities that Adatom
     and HealthCore mutually agree shall be excluded as set forth on Schedule
     3.2(a) hereof, as amended on the Closing Date. The adjustment to the Per
     Share Merger Consideration set forth in this Section 3.2(a) shall be made
     on the Closing Date.

          (b) Indemnification Obligations.  In the event the Surviving
     Corporation shall be obligated to indemnify (i) the holders of record on
     the Closing Date of the shares of Outstanding Adatom Common Stock other
     than Polan (the "Adatom Former Shareholders"), or (ii) the holders of
     record on the Indemnification Adjustment Date (as hereinafter defined) of
     the shares of Common Stock in the Surviving Corporation, other than, and
     specifically excluding, the Adatom Former Shareholders (the "HealthCore
     Former Shareholders"), as the case may be, in respect of the Net
     Indemnification Amount (as defined in Section 8.5 hereof), the Surviving
     Corporation shall issue to such party, on a pro rata basis, the number of
     shares of Common Stock of the Surviving Corporation calculated as follows:
     first, subtract from the HealthCore Post Merger Percentage the product of
     the Net Indemnification Amount multiplied by .00000309 (such difference
     being the "Indemnification HPMP"); second, calculate the percentage
     obtained by dividing the HealthCore Merger Percentage by the
     Indemnification HPMP and subtracting one hundred (100%) percent (the
     difference being the "Indemnification Margin Percentage"); and third,
     multiply the Indemnification Margin Percentage by the number of shares of
     HealthCore Common Stock which were outstanding immediately after the Merger
     purcuant to Section 3.1, including any adjustment in respect of the Closing
     Cash Amount pursuant to Section 3.2(a) hereof (such product being the "Net
     Indemnification Shares"). The Net Indemnification Shares shall be divided
     among, in the case of the Surviving Corporation's indemnification of the
     (A) Adatom Former Shareholders, the Adatom Former Shareholders based on the

                                      A-5
<PAGE>
     number of shares of Common Stock of the Surviving Corporation held by the
     Adatom Former Shareholders on the Indemnification Adjustment Date, or
     (B) HealthCore Former Shareholders, the HealthCore Former Shareholders
     based on the number of shares of Common Stock of the Surviving Corporation
     outstanding on the Indemnification Adjustment Date, excluding the shares of
     Common Stock of the Surviving Corporation held by the Adatom Former
     Shareholders. The indemnification adjustment set forth in this
     Section 3.2(b) shall be made thirteen (13) months following the Closing
     Date (the "Indemnification Adjustment Date") in accordance with the
     provisions of Article VIII hereof.

                                   ARTICLE IV
                        PAYMENT OF MERGER CONSIDERATION

     4.1 Delivery of Certificates.  As soon as reasonably practicable after the
Effective Time, and upon surrender of a Certificate for cancellation to the
Surviving Corporation, together with such documents as may reasonably be
required by the Surviving Corporation, each holder of a Certificate shall be
entitled to receive, and the Surviving Corporation shall issue and deliver to
such holder, in exchange therefor certificates representing shares of HealthCore
Common Stock, rounded up to the nearest whole number, equal to the product of
(A) the number of shares of Adatom Common Stock represented by such Certificate,
multiplied by (B) the Per Share Merger Consideration, and the Certificate so
surrendered shall forthwith be canceled. If certificates for the HealthCore
Common Stock deliverable hereunder are to be issued in a name other than that in
which the Certificate surrendered for exchange is registered, it shall be a
condition of such issuance that the Certificate so surrendered shall be properly
endorsed, with the signature guaranteed, or otherwise in proper form for
transfer and that the party requesting such issuance shall pay to the Surviving
Corporation any transfer or other taxes required by reason thereof, and shall be
deemed (other than Polan) to be an Adatom Former Shareholder for the purposes of
this Agreement, including, without limitation, under the indemnification
provisions set forth in Sections 3.2(b) and Article VIII of this Agreement.
Until surrendered as contemplated by this Section 4.1, after the Effective Time,
each Certificate shall represent only the right to receive, upon such surrender,
the applicable Per Share Merger Consideration.

     4.2 Distributions.  Each holder, upon surrender of a Certificate as herein
provided and acceptance thereof by the Surviving Corporation, shall be entitled
to payment of all dividends or other distributions or payments made or payable
with respect to HealthCore Common Stock with a record date after the Effective
Time and prior to the date of surrender of the Certificate, all without
interest, based upon the number of shares of HealthCore Common Stock issued to
such holder in payment of the Per Share Merger Consideration.

     4.3 No Further Transfers.  After the Effective Time, there shall be no
further transfer of Certificates on the books and records of Adatom or its
transfer agent

     4.4 Appraisal Rights.  Notwithstanding anything contained herein to the
contrary, in the event that holders of shares of HealthCore Common Stock
outstanding immediately prior to the Effective Time shall not have voted in
favor of the Merger, in person or by proxy, or consented thereto in writing,
(such holders, the "Dissenting Shareholders"), then, in such event the shares of
HealthCore Common Stock held by such Dissenting Shareholders shall entitle the
holders thereof to receive payment of the fair value of such shares of
HealthCore Common Stock in accordance with the provisions of Section 262 of the
DGCL. Nothing contained herein shall be construed to relieve a Dissenting
Shareholder from compliance with all of the provisions of the DGCL.

                                   ARTICLE V
                         REPRESENTATIONS AND WARRANTIES

     5.1 Representations and Warranties of Adatom.  Adatom represents and
warrants to HealthCore as follows:

          (a) Organization and Authority.  Adatom is a corporation duly
     organized, validly existing and in good standing under the laws of the

     conducted, is duly qualified, authorized and in good standing to transact
     business in the states listed in Section 5.1(a) of the disclosure schedule
     delivered to HealthCore by Adatom on or prior to the date hereof (the

                                      A-6
<PAGE>
     required to be qualified as a foreign corporation in any other jurisdiction
     where failure to qualify would have a Material Adverse Effect on Adatom.

          (b) Capitalization.  As of the date hereof, the authorized capital
     stock of Adatom consists of 10,000,000 shares of Adatom Common Stock of
     which, (A) 2,384,600 shares are issued and outstanding, (B) no shares are
     held in the treasury of Adatom, and (C) no shares are reserved for future
     issuance upon the exercise of Adatom Options and Adatom Warrants, which
     options and warrants have a term, exercise price, vesting schedule and
     other material terms set forth in Section 5.1(b) of the Adatom Disclosure
     Schedule. The outstanding shares of Adatom Common Stock have been duly
     authorized and are validly issued, fully paid and nonassessable, and,
     except as set forth in this Section 5.1(b) or in Section 5.1(b) of the
     Adatom Disclosure Schedule, there are no outstanding rights, subscriptions,
     warrants, calls, preemptive rights, options or other agreements or
     commitments of any kind or character to purchase or otherwise to acquire
     from Adatom any shares of its capital stock or any other security, and no
     security or obligation of any kind convertible into the capital stock or
     other security of Adatom exists in favor of any Person (as hereinafter
     defined). Except as set forth in Section 5.1(b) of the Adatom Disclosure
     Schedule, Adatom has no outstanding bonds, debentures, notes or other such
     obligations the holders of which have the right to vote or which are
     convertible into or exercisable for securities having the right to vote
     with the shareholders of Adatom on any matter. Other than as contemplated
     by this Agreement or as set forth in Section 5.1(b) of the Adatom
     Disclosure Schedule, there are no outstanding contractual obligations,
     commitments, understandings or arrangements of Adatom to repurchase, redeem
     or otherwise acquire or make any payment in respect of any shares of
     capital stock or other equity securities or ownership interests of Adatom.

          (c) Articles of Incorporation, By-Laws, Corporate Records and
     Committees.  The copies of the Articles of Incorporation and By-Laws or
     equivalent organizational documents, each as amended to date, of Adatom
     delivered to HealthCore on or prior to the date hereof are correct and
     complete. The stock transfer, minute books and corporate records of Adatom
     which have been made available to HealthCore, are correct and complete and
     constitute the only written records and minutes of the meetings,
     proceedings, and other actions of the Board of Directors and the
     shareholders of Adatom from its date of incorporation.

          (d) Financial Statements.  The audited balance sheet of Adatom as at
     December 31, 1998 (the "Adatom Audited Balance Sheet"), the unaudited
     balance sheet of Adatom as at March 31, 1999 (the "Adatom Unaudited Balance
     Sheet", and, together with the Adatom Audited Balance Sheet, the "Adatom
     Balance Sheets" ) and, with respect to the Adatom Audited Balance Sheet,
     the related audited statements, and, with respect to the Adatom Unaudited
     Balance Sheet, the related unaudited statements, of income, capital and
     cash flows for the three years then ended (as such documents may have been
     amended to date) heretofore delivered to HealthCore, have been prepared in
     accordance with generally accepted accounting principles ("GAAP") applied
     on a consistent basis during the periods involved (except as may be
     indicated in the notes thereto subject), subject to year end audit
     adjustments for the Adatom Unaudited Balance Sheet, and are true and
     correct in all material respects and fairly present the financial condition
     and the results of operations and cash flow of Adatom as at the date and

          (g) Non-Contravention.  The performance of this Agreement will not
     (i) violate any provision of the Articles of Incorporation or By-Laws or
     equivalent organizational document of Adatom; (ii) violate, conflict with
     or result in the breach or termination of, or constitute an amendment to,
     or otherwise give any Person the right to terminate, or constitute (or with
     notice or lapse of time or both would constitute) a default (by way of
     substitution, novation or otherwise) under the terms of, any contract,
     mortgage, lease, bond, indenture, agreement, franchise or other instrument
     or obligation to which Adatom is a party or by which Adatom or any of its
     assets or properties are bound; (iii) result in the creation of any lien,
     mortgage, claim, charge, security interest, encumbrance, restriction or
     limitation (collectively, "Liens") upon the properties or assets of Adatom
     pursuant to the terms of any contract, mortgage, lease, bond, indenture,
     agreement, franchise or other instrument or obligation to which Adatom is a
     party or by which Adatom or any of its assets or properties are bound;
     (iv) violate any judgment, order, injunction, decree or award of any court,

     or regulation of any jurisdiction as such statute, law, rule or regulation
     relates to any of its securities, properties, assets or business; or
     (vi) violate any Permit (as herein defined).

          (h) Tangible Property.  Adatom has good title to all of the assets
     reflected on its books and records and on the Adatom Balance Sheets, free
     and clear of all Liens, except for those assets leased by Adatom under
     those leases listed in Section 5.1(h) of the Adatom Disclosure Schedule.
     All furniture, fixtures and equipment owned or used by Adatom
     (collectively, the "Fixed Assets") will be in substantially the same
     condition at Closing as existed on the date of this Agreement, reasonable
     wear and tear excepted.

          (i) Real Property and Leases.  Section 5.1(i) of the Adatom Disclosure
     Schedule sets forth a true and correct list of all leases, subleases or
     other agreements under which Adatom is lessee or lessor of any real
     property or has any interest in real property and, except as set forth in
     Section 5.1(i) of the Adatom Disclosure Schedule, there are no rights or
     options held by Adatom or any contractual obligations on its part to
     purchase or otherwise acquire (including by way of lease or sublease) any
     interest in or use of any real property, nor any rights or options granted
     by Adatom, or any contractual obligations entered into by it, to sell or
     otherwise dispose of (including by way of lease or sublease) any interest
     in or use of any real property. All such leases, subleases and other
     agreements are in full force and effect and constitute legal, valid and
     binding obligations of Adatom and, to the knowledge of Adatom, the other
     parties thereto, with no existing or, to the knowledge of Adatom, claimed
     default or event of default, or event which with notice or lapse of time or
     both would constitute a default or event of default, by Adatom or, to the
     knowledge of Adatom, by any other party thereto, which would have a
     Material Adverse Effect on Adatom. Adatom is not in violation of any
     building, zoning, health, safety, environmental or other law, rule or
     regulation the violation of which would have a Material Adverse Effect on
     Adatom and no notice from any Person has been served upon Adatom claiming
     any such violation.

          (j) Intellectual Property.  Section 5.1(j) of the Adatom Disclosure
     Schedule sets forth all material trademarks, trade names, trade secrets,
     patents, inventions, processes, registered copyrights, or other
     intellectual property rights (or applications therefor) used by Adatom in
     connection with its business.

          (k) Tax Matters.  Adatom has timely filed all federal, state, county
     and local tax returns, estimates and reports (collectively, "Returns")
     required to be filed by it through the date hereof, copies of which have
     been delivered to HealthCore, which Returns accurately reflect, in all
     material respects, the taxes due for the periods indicated, and Adatom has
     paid in full all income, gross receipts, value added, excise, property,
     franchise, sales, use, employment, payroll and other taxes of any kind
     whatsoever (collectively, "Taxes") shown to be due by such Returns, and has
     established adequate reserves with respect to any liabilities for Taxes
     accrued through March 31, 1999, which are reflected on the Adatom Balance
     Sheets. Adatom does not know of any unassessed deficiency for Taxes
     proposed or threatened against Adatom, and, to Adatom's knowledge, no
     taxing authority has raised any issue with respect to Adatom which, if
     adversely determined, would result in a liability for any Tax which has not
     been reserved against on the Adatom Balance Sheets. No extensions with
     respect to the dates on which any Return was or is due to be filed by
     Adatom nor any waivers or agreements by Adatom for the extension of time
     for the assessment or payment of any Taxes are in force. Adatom has not
     been, and, to Adatom's knowledge, currently is not being, audited by any
     federal, state or local tax authority.

                                      A-8

          (l) Compliance with Laws.  Adatom is in compliance with all applicable
     laws, rules and regulations, the violation of which could have a Material
     Adverse Effect on its assets, properties, liabilities, business, results of
     operations, condition (financial or otherwise) or prospects, nor does
     Adatom know of the enactment, promulgation or adoption of any such law,
     rule or regulation which is not yet effective.

          (m) Permits and Licenses.  Except as set forth in Section 5.1(m) of
     the Adatom Disclosure Schedule, Adatom (including, without limitation, its
     employees) has duly obtained and holds in full force and effect all
     consents, authorizations, permits, licenses, orders or approvals of, and
     has made all declarations and filings with, all Governmental Entities that
     are material in the conduct of its business (collectively, the "Permits");
     all the Permits were duly obtained and are in full force and effect; no
     violations have been recorded by any Governmental Entity in respect of any
     such Permit and no proceeding is pending or, to Adatom's knowledge,
     threatened to revoke, deny or limit any such Permit.

          (n) Contracts and Agreements.  Section 5.1(n) of the Adatom Disclosure

     mortgages and commitments to which Adatom is a party or by which it may be
     bound (individually a "Material Contract", and collectively, "Material

     obligations of Adatom and, to the knowledge of Adatom, the other parties
     thereto, and are in full force and effect on the date hereof, and Adatom

     is not in default under any such Material Contract nor, to the knowledge of
     Adatom, is any other party to any such Material Contract in default
     thereunder, nor does any condition exist that, with notice or lapse of
     time, or both, would constitute a default or event of default thereunder by
     Adatom or, to the knowledge of Adatom, by any other Person. Except as set
     forth in Section 5.1(n) of the Adatom Disclosure Schedule, no Material
     Contract requires the consent or approval of a third party in connection
     with the performance by Adatom of this Agreement or the transactions
     contemplated to be performed by it hereunder.

        of such policy) or other death benefit plans, profit sharing, deferred
        compensation, stock option, bonus or other incentive plans, vacation

        amended, and applicable regulations and Internal Revenue Service
        rulings, notices and other pronouncements.

     meetings, proceedings, and other actions of the Board of Directors and the
     shareholders of HealthCore from its date of incorporation to the date
     hereof.

          (d) SEC Documents.  HealthCore has made available to Adatom a true and
     complete copy of each form, report, schedule and registration statement

     preliminary material) that HealthCore was required to file with the SEC
     since such date. As of their respective dates, the HealthCore SEC Documents
     (other than preliminary material) complied in all material respects with
     the requirements of the Securities Act or the Exchange Act of 1934 (the
     "Exchange Act") as applicable, and the rules and regulations of SEC
     thereunder applicable to such HealthCore SEC Documents, and none of the
     HealthCore SEC Documents, as such documents have been amended to date
     (including all financial statements included therein and exhibits and
     schedules thereto and documents incorporated by reference therein),
     contained any untrue statement of a material fact or omitted 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

                                      A-12

     misleading. HealthCore (i) has filed in a timely manner all reports
     required to be filed during the twelve (12) calendar months immediately
     preceding the date of the execution of this Agreement, and (ii) has not
     been in default, in any material respect, in the payment of (A) any
     installment or installments on indebtedness for borrowed money, or (B) any
     rental on one or more long term leases, which defaults, in the aggregate
     have had a Material Adverse Effect on the financial condition of
     HealthCore.

          (e) Financial Statements.  The audited balance sheet of HealthCore as
     at September 30, 1998 (the "HealthCore Audited Balance Sheet"), the
     unaudited balance sheet of HealthCore as at March 31, 1999 (the "HealthCore
     Unaudited Balance Sheet", and, together with HealthCore Audited Balance
     Sheet, the "HealthCore Balance Sheets"), and, with respect to the
     HealthCore Audited Balance Sheet the related audited statements, and, with
     respect to the HealthCore Unaudited Balance Sheet, the related unaudited
     statements, of income, capital and cash flows for the three years then
     ended, included in HealthCore SEC Documents (as such documents may have
     been amended to date) and heretofore delivered to Adatom, comply as to form
     in all material respects with applicable accounting requirements and with
     the rules and regulations of the SEC with respect thereto, have been
     prepared in accordance with GAAP applied on a consistent basis during the
     periods involved (except as may be indicated in the notes thereto or, in
     the case of the unaudited financial statements, as permitted by Exchange
     Act Form 10-Q) and are true and correct and fairly present (subject, in the
     case of the unaudited financial statements, to normal, recurring audit
     adjustments that, individually and in the aggregate, were not material) the
     consolidated financial condition and the results of operations and cash
     flows of HealthCore as at the respective dates and for the respective
     periods covered thereby and the consolidated results of their operations
     and cash flows for the periods then ended. The sum of all cash on hand of
     HealthCore as at June 1, 1999 is estimated to be approximately Two Million
     Four Hundred Fifty Thousand ($2,450,000) Dollars, after giving effect to
     the sums loaned by HealthCore to Adatom pursuant to the Note.

          (f) Authority.  The Board of Directors of HealthCore has unanimously
     approved this Agreement, the Merger and the other transactions contemplated
     hereby and has recommended that its shareholders vote in favor of the
     adoption and approval of this Agreement and the Merger (the "HealthCore
     Recommendation"). The affirmative vote of a majority of the votes that the
     holders of the outstanding shares of HealthCore Common Stock are entitled
     to cast with respect to the adoption and approval of this Agreement and the
     Merger is the only vote of the holders of any class or series of the
     capital stock of HealthCore necessary to approve this Agreement, the Merger
     and the transactions contemplated hereby, and HealthCore has all other
     requisite corporate power and authority to enter into this Agreement and to
     perform its obligations hereunder and to consummate the transactions
     contemplated hereby. This Agreement has been duly and validly executed and
     delivered by HealthCore and constitutes a valid and binding obligation of
     HealthCore enforceable against HealthCore in accordance with its terms,
     subject to the approval of this Agreement, the Merger and the transactions
     contemplated hereby by the shareholders of HealthCore.

          (g) Merger Shares.  The HealthCore Common Stock to be delivered
     hereunder, when issued in accordance with the terms of this Agreement, will
     be validly issued, fully paid and non-assessable.

          (h) Governmental Authorizations and Other Consents.  Except as set
     forth in Section 5.2(h) of the HealthCore Disclosure Schedule, no consent,
     order, license, approval or authorization of, or exemption by, or
     registration or declaration or filing with, any Governmental Entity, and no
     consent or approval of any other Person, is required to be obtained or made
     by HealthCore in connection with the performance by HealthCore of this
     Agreement or the consummation of the transactions contemplated to be
     performed by it hereunder.

          (i) Non-Contravention.  Except as set forth in Section 5.2(i) of the
     HealthCore Disclosure Schedule, as amended on the Closing Date with respect
     to Subsection (ii) hereof in connection with the Merger or the transactions
     contemplated thereby, on the Closing Date, the performance of this
     Agreement will not (i) violate any provision of the Certificate of
     Incorporation or By-Laws or equivalent organizational document of
     HealthCore; (ii) violate, conflict with or result in the breach or
     termination of, or constitute an amendment to, or otherwise give any Person
     the right to terminate, or constitute (or with notice or lapse of time or
     both would constitute) a default (by way of substitution, novation or
     otherwise) under the terms of, any contract, mortgage, lease, bond,
     indenture, agreement, franchise or other instrument or obligation to

                                      A-13
<PAGE>
     which HealthCore is a party or by which HealthCore or any of its assets or
     properties are bound, all as set forth on Schedule 3.2(a) hereof;
     (iii) result in the creation of any Liens upon the properties or assets of
     HealthCore pursuant to the terms of any contract, mortgage, lease, bond,
     indenture, agreement, franchise or other instrument or obligation to which
     HealthCore is a party or by which HealthCore or any of its assets or
     properties are bound (iv) violate any judgment, order, injunction, decree
     or award of any court, arbitrator, administrative agency or Governmental
     Entity against, or binding upon, HealthCore or any of its securities,
     properties, assets or businesses; (iv) constitute a violation by HealthCore
     of any statute, law, rule or regulation of any jurisdiction as such
     statute, law, rule or regulation relates to any of its securities,
     properties, assets or business; or (v) violate any Permit.

          (j) Tangible Property.  HealthCore has good title to all of the assets
     reflected on its books and records and on the HealthCore Balance Sheets
     that have not been sold or liquidated as contemplated by this Agreement,
     free and clear of all Liens, except for those assets leased by HealthCore
     under those leases listed in Section 5.2(j) of the HealthCore Disclosure
     Schedule as amended on the Closing Date in connection with this Agreement,
     the Merger or the transactions contemplated hereby or thereby. All Fixed
     Assets of HealthCore that have not been sold or liquidated as of the
     Closing Date as contemplated by this Agreement will be in substantially the
     same condition at Closing as existed on the date of this Agreement,
     reasonable wear and tear excepted.

          (k) Real Property and Leases.  Section 5.2(k) of the HealthCore
     Disclosure Schedule sets forth a true and correct list of all leases,
     subleases or other agreements under which HealthCore is lessee or lessor of
     any real property or has any interest in real property and, except as set
     forth in Section 5.2(k) of the HealthCore Disclosure Schedule, there are no
     rights or options held by HealthCore or any contractual obligations on its
     part to purchase or otherwise acquire (including by way of lease or
     sublease) any interest in or use of any real property, nor any rights or
     options granted by HealthCore, or any contractual obligations entered into
     by it, to sell or otherwise dispose of (including by way of lease or
     sublease) any interest in or use of any real property. Except as set forth
     in Section 5.2(k) of the HealthCore Disclosure Schedule, as amended on the
     Closing Date in connection with the Merger or the transactions contemplated
     thereby, all such leases, subleases and other agreements that are set forth
     on Schedule 3.2(a) hereof are in full force and effect and constitute
     legal, valid and binding obligations of HealthCore and, to the knowledge of
     HealthCore, the other parties thereto, with no existing or, to the
     knowledge of HealthCore, claimed default or event of default, or event
     which with notice or lapse of time or both would constitute a default or
     event of default, by HealthCore or, to the knowledge of HealthCore, by any
     other party thereto, which would have a Material Adverse Effect on
     HealthCore. HealthCore is not in violation of any building, zoning, health,
     safety, environmental or other law, rule or regulation the violation of
     which would have a Material Adverse Effect on HealthCore and no notice from
     any Person has been served upon HealthCore claiming any such violation.

          (l) Tax Matters.  HealthCore has timely filed all federal, state,
     county and local Returns required to be filed by it through the date
     hereof, copies of which have been delivered to Adatom, which Returns
     accurately reflect, in all material respects, the taxes due for the periods
     indicated, and HealthCore has paid in full all Taxes shown to be due by
     such Returns, and has established adequate reserves with respect to any
     liabilities for Taxes accrued through March 31, 1999, which are reflected
     on the HealthCore Balance Sheets. HealthCore does not know of any
     unassessed deficiency for Taxes proposed or threatened against HealthCore,
     and, to HealthCore's knowledge, no taxing authority has raised any issue
     with respect to HealthCore which, if adversely determined, would result in
     a liability for any Tax which has not been reserved against on the
     HealthCore Balance Sheets. No extensions with respect to the dates on which
     any Return was or is due to be filed by HealthCore nor any waivers or
     agreements by HealthCore for the extension of time for the assessment or
     payment of any Taxes are in force. HealthCore has not been, and, to
     HealthCore's knowledge, currently is not being, audited by any federal,
     state or local tax authority.

          (m) Compliance with Laws.  HealthCore is in compliance with all
     applicable laws, rules and regulations, the violation of which could have a
     Material Adverse Effect on its assets, properties, liabilities, condition
     (financial or otherwise) or prospects, nor does HealthCore know of the
     enactment, promulgation or adoption of any such law, rule or regulation
     which is not yet effective.

                                      A-14

          (n) Permits and Licenses.  Except as set forth in Section 5.2(n) of
     the HealthCore Disclosure Schedule, HealthCore (including, without
     limitation, its employees) duly obtained all Permits that were material in
     the conduct of its business, and no violations have been recorded by any
     Governmental Entity in respect of any such Permit.

          (o) Contracts and Agreements.  Section 5.2(o) of the HealthCore
     Disclosure Schedule lists all written and oral Material Contracts to which
     HealthCore is a party or by which it may be bound. Except as set forth in
     Section 5.2(o) of the HealthCore Disclosure Schedule, as amended on the
     Closing Date, all Material Contracts set forth on Schedule 3.2(a) hereof
     constitute legal, valid and binding obligations of HealthCore and, to the
     knowledge of HealthCore, of the other parties thereto, and are in full
     force and effect on the date hereof, and HealthCore has paid in full all
     amounts due thereunder which are due and payable and is not in default
     under any such Material Contract nor, to the knowledge of HealthCore, is
     any other party to any such Material Contract in default thereunder, nor
     does any condition exist that, with notice or lapse of time, or both, would
     constitute a default or event of default thereunder by HealthCore or, to
     the knowledge of HealthCore, by any other Person. Except as set forth in
     Section 5.2(o) of the HealthCore Disclosure Schedule, as amended on the
     Closing Date, no Material Contract set forth on Schedule 3.2(a) of this
     Agreement requires the consent or approval of a third party in connection
     with the performance by HealthCore of this Agreement or the transactions
     contemplated to be performed by it hereunder.

          (p) Employee Compensation and Benefits and Relations.

              (i) Section 5.2(p) of the HealthCore Disclosure Schedule lists all
        current employees of HealthCore, setting forth their respective
        salaries, whether they are employed under contract or at will, and the
        expiration date of each contract.

              (ii) Notwithstanding anything contained in this Agreement to the
        contrary, HealthCore has no liabilities of any kind or nature to any of
        its employees in connection with their employment by HealthCore other
        than (A) for compensation payable to such employees accruing in the
        current pay period and arising in the ordinary course, and
        (B) severance arrangements or contract settlements entered into by
        HealthCore in connection with the sale or liquidation of the HealthCore
        Business (as hereinafter defined) or as contemplated by this Agreement.

             (iii) Except as set forth in Section 5.2(p) of the HealthCore
        Disclosure Schedule, as of the Closing Date all pension, retirement,
        savings, disability, medical, dental or other health plans, life
        insurance (including any individual life insurance policy as to which
        HealthCore makes premium payments whether or not HealthCore is the
        owner, beneficiary or both of such policy) or other death benefit plans,
        profit sharing, deferred compensation, stock option, bonus or other
        incentive plans, vacation benefit plans, severance plans, or other
        employee benefit plans or arrangements (whether written or arising from
        custom) maintained by HealthCore shall have been terminated. Other than
        HealthCore's 401(k) plan, HealthCore does not have any employee pension
        benefit plan as defined in Section 3(2) of ERISA, or any employee
        welfare benefit plan as defined in Section 3(1) of ERISA.

              (iv) HealthCore has, in all material respects, complied with the
        requirements, to the extent applicable, of COBRA with respect to the
        continuation of employer-provided health benefits following a
        "qualifying event" which would otherwise terminate such benefits, as
        provided in Section 4980B of the Internal Revenue Code of 1986, as
        amended, and applicable regulations and Internal Revenue Service
        rulings, notices and other pronouncements.

              (v) HealthCore has not at any time during the last five years had,
        or is there now threatened, a strike, picket, work stoppage, work
        slowdown, or other labor trouble or dispute, and HealthCore does not
        know of any employee's proposed resignation whose annual salary exceeds
        $25,000, other than as contemplated by this Agreement. HealthCore has
        not been, and is currently not, a party to any collective bargaining
        agreements.

          (q) Insurance.  Section 5.2(q) of the HealthCore Disclosure Schedule
     lists all policies of property, theft, fire, liability, workers'
     compensation, title, professional liability or life insurance or other
     insurance owned or maintained by HealthCore or in which HealthCore is a
     named insured, or additional insured, or on which HealthCore or is paying
     any premiums. Except as set forth in Section 5.2(q) of the HealthCore

                                      A-15
<PAGE>
     Disclosure Schedule, all such policies are in full force and effect as of
     the date hereof, and HealthCore is not in default with respect to any
     provision contained in any such insurance policy nor failed to give any
     notice or present any claim thereunder in due and timely fashion.
     Section 5.2(q) of the HealthCore Disclosure Schedule sets forth a summary
     of the claims history for HealthCore under such policies since January 1,
     1999 and, except as set forth in Section 5.2(q) of the HealthCore
     Disclosure Schedule, there are no claims outstanding by HealthCore under
     any such policies.

          (r) Liabilities.  There are no material Liabilities of HealthCore,
     except (a) those accrued, reflected or otherwise provided for on the
     HealthCore Balance Sheets, (b) those incurred in the ordinary course of
     HealthCore's business since December 31, 1998, consistent with past
     practices, no one of which exceeds $25,000, (c) reasonable Transaction
     Expenses incurred by HealthCore, and (d) those listed in
     Section 5.2(r) of the HealthCore Disclosure Schedule.

          (s) Actions and Proceedings.  Except as provided in Section 5.2(s) of
     the HealthCore Disclosure Schedule, there are no Actions, pending or, to
     HealthCore's knowledge, threatened against, or reasonably involving or
     affecting, to HealthCore's knowledge, having performed no investigation,
     HealthCore nor any of its assets, whether or not fully or partially covered
     by insurance or which would give rise to any right of indemnification by
     any Person from HealthCore, and there are, to HealthCore's knowledge, no
     outstanding orders, writs, injunctions, awards, sentences or decrees of any
     court, private body or group or Governmental Entity against, reasonably
     involving or affecting, to HealthCore's knowledge, having performed no
     investigation, HealthCore.

          (t) Absence of Changes.  Except as set forth in Section 5.2(t) of the
     HealthCore Disclosure Schedule, or in connection with the sale or
     liquidation of the HealthCore Business, since December 31, 1998, HealthCore
     has carried on its business in the ordinary course, and there has not been:

              (i) except in the ordinary course, or as contemplated or permitted
        by this Agreement, the incurrence of any obligation or liability
        (whether matured, unmatured, absolute, accrued, contingent or otherwise)
        which exceeds $50,000 in the aggregate, other than: (A) under the terms
        of that certain letter amendment, dated April 26, 1999, between Polan
        and HealthCore, (B) under the terms of the HealthCore Engagement Letter,
        and (C) to David Mullikin ("Mullikin"), HealthCore's President, in
        severance of his employment with HealthCore consisting of (x) cash in
        the amount of One Hundred Thousand ($100,000) Dollars, and (y) options
        to purchase up to one hundred thousand (100,000) shares of HealthCore
        Common Stock at an exercise price of $.10 per share.

          (u) Affiliated Transactions.  For purposes of this Section 5.1(u), an
     "Affiliate" means any HealthCore shareholder or any employee, officer or
     director of HealthCore or any spouse or family member (including in-laws)
     of, or any corporation or other entity "controlled by" (as such term is
     defined in Rule 405 of the General Rules and Regulations under the
     Securities Act), any such persons or in which any such person has an equity
     or ownership interest exceeding five percent.

              (i) Except as specifically set forth (including dollar amounts) in
        Section 5.2(u) of the HealthCore Disclosure Schedule or disclosed in the
        HealthCore SEC Documents, as of the date hereof, no Affiliate is

              (ii) Except as set forth on Section 5.2(u) of the HealthCore
        Disclosure Schedule or disclosed in the HealthCore SEC Documents, during
        the past three (3) years, HealthCore has not, directly or indirectly,
        purchased, leased from or otherwise acquired any property or obtained
        any services from, or sold, leased to or otherwise disposed of any
        property or furnished any services to, or otherwise dealt with, any
        Affiliate nor is HealthCore a party to any contract, agreement, license,
        commitment or other arrangement, written or oral, express or implied,
        with an Affiliate except as disclosed on the HealthCore Disclosure
        Schedule.

          (v) Brokers or Finders.  No agent, broker, investment banker,

          (w) Environmental Matters.  Except as set forth in Section 5.2(w) of
     the HealthCore Disclosure Schedule: (i) HealthCore has obtained and is in
     material compliance with the terms and conditions of all permits, licenses
     and other authorizations required under applicable Environmental Laws;
     (ii) to HealthCore's knowledge, no asbestos in a friable condition or
     equipment containing polychlorinated biphenyls or leaking underground or
     above-ground storage tanks is contained in or located at any facility
     owned, leaned or controlled by HealthCore; (iii) HealthCore is in material
     compliance with all applicable Environmental Laws, and has fully disclosed
     to Adatom all known material past and present non-compliance with
     Environmental Laws, and all known past discharges of emissions, leaking or
     releases known to HealthCore of any substance or waste regulated under or
     defined by Environmental Laws that could reasonably be expected to form the
     basis of any claim, action, suit, proceeding, hearing or investigation
     under any applicable Environmental Laws; and (iv) HealthCore has not
     received notice of any past or present events, conditions, circumstances,
     activities, practices, incidents, actions or plans that have resulted in or
     threaten to result in any common law or legal liability, or otherwise form
     the basis of any claim, action, suit, proceeding, hearing or investigation
     under any applicable Environmental Laws; provided, however, that clauses
     (i) through (iv) address only those matters that would have a Material
     Adverse Effect with respect to HealthCore.

          (x) Investment Company Act.  HealthCore either (i) is not an
     "investment company," or a company "controlled" by an "affiliated company"
     with respect to an "investment company," required to register under the
     Investment Company Act of 1940, as amended (the "Investment Company Act")
     or (ii) satisfies all conditions for an exemption from the Investment
     Company Act, and, accordingly, HealthCore is not required to be registered
     under the Investment Company Act.

          (y) Compliance with Securities Laws, Rules and
     Regulations.  HealthCore has complied with all applicable state and federal
     securities laws, rules and regulations in connection with the offer and

                                   ARTICLE VI
                                   COVENANTS

     6.1 Covenants of Adatom.  Adatom hereby covenants and agrees that, except

defined) it shall comply with the following covenants:

          (a) Ordinary Course.  Adatom shall carry on its businesses in the
     usual, regular and ordinary course in substantially the same manner as
     heretofore conducted and use its commercially reasonable, good faith
     efforts to preserve intact its current business organizations, keep
     available the services of its current officers and employees and preserve
     its relationships with material customers, suppliers, contractors,
     distributors, licensors, licensees and others having business dealings with
     it to the end that its goodwill and ongoing business shall not be impaired
     in any material respect at the Closing Date. Without limiting the
     generality of the foregoing, and except as contemplated by this Agreement,
     or as otherwise required by law, Adatom shall not:

        capital stock, any other voting securities or any securities convertible
        into, or any rights, warrants or options to acquire, any such shares,
        voting securities or convertible securities or any other securities or
        equity equivalents (including without limitation stock appreciation
        rights) other than (A) issuances upon exercise of employee and director
        stock options

     (A) through (C) only after the Board of Directors of HealthCore concludes

     HealthCore from outside counsel to HealthCore that such action is
     reasonably necessary for the Board of Directors of HealthCore to comply

     shall not withdraw or modify or propose to withdraw or modify in a manner
     adverse to Adatom, the HealthCore Recommendation, unless the Board of

     written opinion addressed to it from outside counsel to HealthCore that
     such action is necessary for the Board of Directors of HealthCore to comply
     with its fiduciary obligations to shareholders under applicable law.
     HealthCore shall use its best efforts to solicit from its shareholders
     proxies in favor of the approval and adoption of this Agreement and the
     transactions contemplated hereby, and to secure the vote or the consent of
     the shareholders required by the DGCL to approve and adopt this Agreement
     and the transactions contemplated hereby.

           either of their respective Affiliates to, take or cause to be taken
           any action, whether before or after the Effective Time, that would
           disqualify the Merger as a "reorganization" within the meaning of
           Section 368(a) of the Internal Revenue Code of 1989, as amended (the
           "Code"). Each of Adatom and HealthCore agrees to use its reasonable
           best efforts to cure any impediment to the qualification of the
           Merger as a "reorganization" within the meaning of
           Section 368(a) of the Code.

                (B) Adatom shall instruct its accountants to deliver and shall
           use its reasonable best efforts to cause such accountants to deliver
           to HealthCore letters dated as of the Closing Date, addressed to
           HealthCore, containing such matters as are customarily contained in
           auditors' letters regarding information about Adatom included in the
           Proxy/Registration Statement, which auditors' letters shall be in
           form and substance reasonably satisfactory to HealthCore.

                (C) All Returns required to be filed by or with respect to each
           party (or any of them) after the date hereof and on or before the
           Effective Time shall be prepared and timely filed, in a manner
           consistent with prior years and applicable laws and regulations other
           than such Returns for which the failure to file would not have a
           Material Adverse Effect with respect to such party.

              (ix) Affiliates.  Attached hereto as Exhibit D is a list of names
        and addresses of those Persons who may, in the opinion of Adatom (after
        consultation with outside legal counsel), "Affiliates" of Adatom within
        the meaning of Rule 145 under the Securities Act. Adatom shall exercise
        its best efforts to deliver or cause to be delivered to HealthCore,
        prior to the Effective Time, from each affiliate of Adatom identified in
        the foregoing list, a letter in the form attached as Exhibit E (the
        "Adatom Affiliates Letter"). The certificates representing HealthCore
        Common Stock received by such Affiliates shall bear a customary legend
        regarding applicable Securities Act restrictions.

               (x) Other Actions.  HealthCore and Adatom shall not take any
        action that would or is reasonably likely to result in any of the
        representations and warranties of HealthCore or Adatom, as the case may
        be, set forth in this Agreement being untrue in any material respect as
        of the date made, or in any of the conditions to the Closing set forth

        "Registration Rights Agreements") in form and substance reasonably
        satisfactory to Polan and Mullikin, as the case may be, and Adatom, and
        each of their respective counsel, covering the shares of stock in the

        Rights Agreement shall provide that (A) Polan and Mullikin shall have

        days following the Closing, Polan and Mullikin shall have the right to
        demand registration of such shares on any appropriate form registration
        statement other than, and specifically excluding, on a Form S-1
        registration statement, pursuant to the terms of the Registration Rights
        Agreements; provided, however, that with respect to the Polan Escrowed

        business in compliance with all applicable laws and regulations except

     8.1 Survival.  All representations and warranties made in this Agreement
shall survive the delivery of this Agreement for a period of one (1) year
following the Closing Date. Notwithstanding the foregoing, any claim for
indemnification that is asserted by written notice as provided in Section 8.4
within the survival period shall survive until resolved pursuant to a final
non-appealable judicial determination or otherwise.

     8.2 Indemnification of HealthCore.  The Surviving Corporation shall
indemnify, defend and hold the HealthCore Former Shareholders from and against
any and all loss, damage, cost or expense, including reasonable attorneys' fees
and expenses (collectively, "Losses"), caused by any misrepresentation, breach
of warranty or failure to fulfill any covenant or agreement made by Adatom
contained herein (the aggregate monetary sum of such indemnification obligations
being the "Adatom Indemnification Amount").

     8.3 Indemnification of Adatom.  The Surviving Corporation shall indemnify,
defend and hold harmless the Adatom Former Shareholders from and against any and
all Losses caused by any misrepresentation, breach of warranty or failure to
fulfill any covenant or agreement made by HealthCore contained herein (the
aggregate monetary sum of such indemnification obligations being the "HealthCore
Indemnification Amount").

     8.4 Basket; Limitation of Liability.  The Surviving Corporation's
obligation to indemnify the Adatom Former Shareholders or the HealthCore Former

unless and until the Adatom Former Shareholders or the HealthCore Former
Shareholders, as the case may be, shall have suffered aggregate Losses in excess
of One Hundred Thousand ($100,000) Dollars (the "Indemnification Threshold"). In
the event the Losses suffered by the Adatom Former Shareholders or the
HealthCore Former Shareholders, as the case may be, exceed the Indemnification
Threshold, the Surviving Corporation shall only be obligated to indemnify the
Adatom Former Shareholders or the HealthCore Former Shareholders, as the case
may be, from and against aggregate Losses in excess of the Indemnification
Threshold. In no event shall the Surviving Corporation's obligation to indemnify
the Adatom Former Shareholders and the HealthCore Former Shareholders exceed, in
each case, the aggregate sum of Five Hundred Thousand ($500,000) Dollars.

          (a) The party entitled to indemnification shall take all reasonable
     steps to mitigate all indemnifiable liabilities and damages upon and after

     shall be entitled to indemnification to the extent of any available
     insurance relating to any indemnifiable claim.

          (b) The party seeking indemnification shall give written notice to the
     indemnifying party of the facts and circumstances giving rise to any claim
     for indemnification as soon as reasonably possible but in any event within
     thirty (30) days after obtaining knowledge of the basis for a claim for
     indemnification hereunder. With respect to each third party claim subject
     to this Article 8 (a "Third Party Claim"), the party seeking
     indemnification shall give prompt written notice to the indemnifying party
     of the Third Party Claim.

     agreed to by HealthCore and Adatom); provided, however, that neither party
     may terminate this Agreement under this Section 9.1(c) if the failure has
     been caused by such party's material breach of this Agreement;

     receive the requisite vote for approval and adoption by the shareholders of
     HealthCore at the HealthCore Shareholders' Meeting;

          (e) by either HealthCore or Adatom if (i) the Board of Directors of
     HealthCore shall have recommended to the shareholders of HealthCore a
     Qualified Transaction Proposal; (ii) a tender offer (not including a
     self-tender offer) or exchange offer for shares of capital stock of
     HealthCore, which would result in the beneficial ownership by any Person or
     any "group" (as defined in Section 13(d) of the Exchange Act and the rules
     and regulations promulgated thereunder) of more than 25% of the outstanding
     shares of any class of capital stock of HealthCore, is commenced, and the

     HealthCore tender their shares in such tender or exchange offer; or
     (iii) any Person shall have acquired beneficial ownership or the right to
     acquire beneficial ownership of, or any "group" shall have been formed
     which beneficially owns, or has the right to acquire "beneficial ownership"
     of, more than 25% of the then outstanding shares of any class of capital
     stock of HealthCore; or

     consummation of the Merger and such order, decree, ruling or other action
     shall have become final and nonappealable.

the Merger abandoned pursuant to Section 9.1, all further obligations of the
parties hereunder shall terminate except that the obligations set forth in
Sections 6.3(a)(i) and this Section 9.2 shall survive, the Note shall become due
and payable in accordance with the terms thereof; provided that, if this
Agreement is so terminated by a party because one or more of the conditions to
such party's obligations hereunder is not satisfied as a result of the other
party's willful or knowing

                                      A-29
<PAGE>
failure to comply with its obligations under this Agreement, the terminating
party's right to pursue all legal remedies for breach of contract or otherwise,
including, without limitation, damages relating thereto, shall also survive such
termination unimpaired.

                         OPINION OF HEALTHCORE BOARD OF
                          DIRECTORS' FINANCIAL ADVISOR

                                                                 August 30, 1999

The Board of Directors
HealthCore Medical Solutions, Inc.
11904 Blue Ridge Boulevard
Grandview, Missouri 64030

Gentlemen:

     HealthCore Medical Solutions, Inc. (the "Company") has under consideration
a transaction pursuant to which the Company would engage in a business
combination (the "Merger") with Adatom, Inc. ("Adatom") as a result of which the
Company will issue 10,689,489 shares of the Company's common stock (the "Common
Stock") to Adatom's shareholders, an exchange ratio of 2.17 shares of Common
Stock for each share of Adatom's common stock (the "Exchange Ratio"), at which
time Adatom's shareholders will hold approximately 77.5% of the combined
company's outstanding Common Stock, subject to adjustment. The Exchange Ratio
will be increased by 0.0179 of a share or an aggregate of 195,000 shares of
Common Stock for every $100,000 by which the Company's cash assets fail to meet
the $2.85 million threshold at the time of closing. The Merger is subject to,
among other things, the approval of the Board of Directors and the shareholders
of the Company.

     In connection with its review and analysis of the Merger, you have
requested our opinion, as investment bankers, as to the fairness to the
shareholders of the Company, from a financial point of view, of the
consideration to be paid in the Merger to Adatom's shareholders in the form of
Common Stock of the Company.

     Kaufman Bros., L.P. as part of its investment banking business is
experienced in valuation of businesses. We are continually engaged in the
valuation of businesses and their securities in connection with mergers and
acquisitions, negotiated underwritings, secondary distributions of securities,
private placements of public and private companies and valuations for corporate
and other purposes.

     In conducting our analysis and arriving at our opinion as expressed herein,
we have reviewed and analyzed, among other things, the following:

          o The Agreement and Plan of Merger dated July 1, 1999, by and between
            the Company and Adatom;

          o a draft of this Form S-4 Registration Statement and Proxy;

          o certain documents and reports filed by HealthCore with the
            Securities and Exchange Commission;

          o certain internal information and documents relating to the Company
            and Adatom provided to us by their respective managements, including
            historical financial information and financial forecasts;

          o the reported prices and trading activity of the Company's common
            stock;

          o the financial and business prospects for the merged entity and the
            industry in which it competes;

          o certain publicly available information concerning certain other
            companies engaged in businesses which it believed to be comparable
            to Adatom and the trading markets for such other companies'
            securities;

          o information concerning recent private equity investments in
            pre-public e-commerce companies we believe to be comparable to
            Adatom; and

          o information concerning certain other business transactions which we
            believe to be relevant to the Merger.

                                      B-1
<PAGE>
     We have also met with or spoken to certain officers and employees of the
Company and Adatom concerning their respective businesses and operations,
assets, present condition and future prospects, and performed such analyses as
we deemed appropriate.

     In arriving at our opinion, we have visited certain of the properties and
facilities of Adatom but have not conducted a physical inspection of such
properties and facilities, nor have we made or obtained any independent
evaluation or appraisal of such properties and facilities or of any of the
assets or liabilities of the Company or Adatom (contingent or otherwise). We
have assumed and relied upon the accuracy and completeness of the financial and
other information used by us in arriving at our opinion, and upon the assurances
of the managements of the Company or Adatom that they are not aware of any
information that would make the information provided to us incomplete or
misleading, and have not attempted to independently verify such information.
With respect to financial forecasts, we were advised by the management of the
Company and Adatom, and we assumed without independent investigation, that they
were reasonably prepared and reflected, as of the times they were delivered to
us, the best currently available estimates and judgment as to the expected
future financial performance of the Company or Adatom, as the case may be.

     This opinion is necessarily based upon financial, economic, market and
other conditions as they existed, and, except as set forth in the preceding
paragraph, the information available to us, as of the date hereof. We disclaim
any undertakings or obligation to advise any person of any change in any fact or
matter affecting this opinion which may come or be brought to our attention
after the date hereof.

     In the ordinary course of our business, we may hold and actively trade
securities of the Company for our own account and for the accounts of our
customers and, accordingly, may at any time hold a long or short position in
such securities.

     This opinion does not constitute a recommendation as to any action the
Board of Directors or any shareholder of the Company should take in connection
with the Merger or any aspect thereof and is not a recommendation to any person
on how such person should vote on the consideration of the Merger. This opinion
relates solely to the fairness to the shareholders of the Company, as of the
date hereof, from a financial point of view, of the consideration to be paid in
the Merger to Adatom's shareholders in the form of Common Stock of the Company.
We express no opinion herein as to the structure, terms or effect of any other
aspect of the Merger or as to the merits of the underlying decision of the
Company to enter into the Merger. Without limiting the foregoing, we express no
opinion as to the financial treatment, audit procedures or other financial
aspects of the Merger or as to any aspect of any arrangements agreed to between
the Company and its officers, directors or shareholders prior to or concurrent
with the Merger.

     This letter is for the information of the Board of Directors of the Company
for its use in evaluating the fairness to the shareholders of the Company as of
the date hereof, from a financial point of view, of the consideration to be paid
in the Merger to Adatom's shareholders in the form of Common Stock of the
Company. It may not be used for any other purpose, published, reproduced,
summarized, described or referred to or given to any other person or otherwise
made public without our prior written consent.

     Based upon and subject to the foregoing, it is our opinion as investment
bankers that, as of the date hereof, the consideration to be paid by the Company
in the form of Common Stock of the Company to Adatom's shareholders is fair to
the shareholders of the Company, from a financial point of view.

                                          Very truly yours,


                                          KAUFMAN BROS., L.P.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     The Certificate of Incorporation and By-Laws of Registrant provide that
Registrant shall indemnify any person to the full extent permitted by the
Delaware General Corporation Law. Reference is hereby made to Section 145 of the
Delaware General Corporation Law relating to the indemnification of officers and
directors which Section is hereby incorporated herein by reference.

     Registrant also has Indemnification Agreements with each of its officers
and directors.

     Registrant presently maintains directors' and officers' liability insurance
coverage with an aggregate policy limit of $7,000,000 for each policy year.

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

ITEM 22. UNDERTAKINGS.

     (a) The undersigned registrant hereby undertakes as follows: 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 an person or party
who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer
undertakes that 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.

     (b) Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of the registrant
pursuant to the foregoing provisions, or otherwise, the registrant has been
advised that in the opinion of the Commission such indemnification is against
public policy as expressed in the Act and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question of whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

     (c) The registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (c) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the 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 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.

     (d) 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 this registration statement through the date
of responding to the request.

     (e) 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.

         NEITHER THIS WARRANT NOR THE WARRANT STOCK HAS BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED. THE COMPANY WILL NOT TRANSFER THIS
WARRANT OR THE WARRANT SHARES UNLESS (i) THERE IS AN EFFECTIVE REGISTRATION
COVERING SUCH WARRANT OR SUCH WARRANT SHARES, AS THE CASE MAY BE, UNDER THE
SECURITIES ACT OF 1933, AS AMENDED, AND APPLICABLE STATES SECURITIES LAWS, (ii)
IT FIRST RECEIVES A LETTER FROM AN ATTORNEY, ACCEPTABLE TO THE BOARD OF
DIRECTORS OR ITS AGENTS, STATING THAT IN THE OPINION OF THE ATTORNEY THE
PROPOSED TRANSFER IS EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933,

Warrant No.                                                        23,313 Shares
           ------


            Void after 5:00 p.m. New York City Time, on July 8, 2004.

    Warrant to Purchase 23,313 Shares of Common Stock, no par value per share


                   WARRANT TO PURCHASE SHARES OF COMMON STOCK

                                       OF

                                  ADATOM, INC.

         This Is To Certify That, FOR VALUE RECEIVED, Jesup & Lamont Securities
Corporation ("Holder") having an address at 650 Fifth Avenue, New York, New York
10019, is entitled to purchase, subject to the provisions of this Warrant
("Warrant"), from Adatom, Inc., a California corporation (the "Company"),
Twenty-Three Thousand Three Hundred Thirteen (23,313) fully paid, validly issued
and non-assessable shares of Common Stock (the "Common Stock"), no par value per
share, of the Company at an exercise price of $ 2.1447 per share at any


                                      - 1 -
<PAGE>


time or from time to time during the period from the date hereof to July 8,
2004, but not later than 5:00 p.m. New York City Time, on July 8, 2004. This
Warrant is being issued pursuant to the terms of a Letter Agreement, dated April
27, 1999, by and between Holder and the Company (the "Engagement Letter") in
connection with the placement of $500,000 of convertible bridge notes of the
Company, dated as of the date hereof (the "Note"). The number of shares of
Common Stock to be received upon the exercise of this Warrant and the price to
be paid for each share of Common Stock may be adjusted from time to time as
hereinafter set forth. The shares of Common Stock deliverable upon such
exercise, and as adjusted from time to time, are hereinafter sometimes referred
to as "Warrant Shares" and the exercise price of a share of Common Stock in
effect at any time and as adjusted from time to time is hereinafter sometimes
referred to as the "Exercise Price."

         (1) EXERCISE OF WARRANT. This Warrant may be exercised in whole or in
part at any time or from time to time on or after the date hereof and until July
8, 2004 (the "Exercise Period"); provided, however, that if such day is a day on
which banking institutions in the State of New York are authorized by law to
close, then on the next succeeding day which shall not be such a day. This
Warrant may be exercised by presentation and surrender hereof to the Company at
its principal office or to the Company's warrant agent, if any has been so
appointed, with the Purchase Form annexed hereto duly executed and accompanied
by payment of the Exercise Price, in cash or by certified or bank cashier's
check, for the number of Warrant Shares specified in such form. Notwithstanding
the foregoing, in lieu of any cash payment required hereunder, the Holder of
this Warrant shall have the right at any time during the Exercise Period to
exercise the Warrant in full or in part by surrender of this Warrant (with the
election at the end hereof duly executed) to the Company at its principal office
or to the Company's warrant agent, if any has been so


                                      - 2 -
<PAGE>


appointed, in exchange for the number of Warrant Shares equal to the product of
(a) the number of Warrant Shares as to which the Warrant is being exercised
multiplied by (b) a fraction, the numerator of which is the Current Market Price
(as defined in Section (11) below) of the Common Stock less the Exercise Price
and the denominator of which is the Current Market Price. As soon as practicable
after each such exercise of the Warrants, the Company shall issue or cause to be
issued and delivered to the Holder a certificate or certificates for the Warrant
Shares issuable upon such exercise, registered in the name of the Holder. The
Warrant shall be deemed to have been exercised immediately prior to the close of
business on the date of any such exercise, provided such exercise is in
accordance with the provisions set forth herein. If this Warrant should be
exercised in part only, the Company shall, upon surrender of this Warrant for
cancellation, execute and deliver a new Warrant evidencing the rights of the
Holder thereof to purchase the balance of the Warrant Shares purchasable
thereunder. Upon receipt by the Company of this Warrant at its office in proper
form for exercise, the Holder shall be deemed to be the holder of record of the
shares of Common Stock issuable upon such exercise, notwithstanding that the
stock transfer books of the Company shall then be closed or that certificates
representing such shares of Common Stock shall not then be physically delivered
to the Holder.

         (2) RESERVATION OF SHARES. The Company shall at all times reserve for
issuance and/or delivery upon exercise of this Warrant such number of shares of
its Common Stock as shall be required for issuance and delivery upon exercise of
the Warrants.

         (3) FRACTIONAL SHARES. No fractional shares or script representing
fractional shares shall be issued upon the exercise of this Warrant. If more
than one Warrant shall be exercised at one time by the Holder, the number of
full shares which shall be issuable upon


                                      - 3 -
<PAGE>


exercise thereof shall be computed on the basis of the aggregate number of full
shares issuable upon such exercise. No adjustment shall be made in respect of
cash dividends on Warrant Shares delivered upon exercise of any Warrant. With
respect to any fraction of a share called for upon exercise hereof, the Company
shall pay to the Holder an amount in cash equal to such fraction multiplied by
the average closing bid and asked prices of the Common Stock on the last
available date for which quotations are available immediately preceding the date
of exercise of this Warrant, or if the bid and asked prices are not so reported,
then the current market value shall be an amount, not less than the book value
thereof as at the end of the most recent fiscal year of the Company ending prior
to the date of the exercise of the Warrant, determined in such reasonable manner
as may be prescribed by the Board of Directors of the Company.

         (4) EXCHANGE OR LOSS OF WARRANT. This Warrant is exchangeable, without
expense, at the option of the Holder, upon presentation and surrender hereof to
the Company for other Warrants of different denominations entitling the holder
thereof to purchase in the aggregate the same number of shares of Common Stock
purchasable hereunder. This Warrant may be divided or combined with other
Warrants which carry the same rights upon presentation hereof at the principal
office of the Company with a written notice specifying the denominations in
which new Warrants are to be issued and signed by the Holder hereof. The term
"Warrant" as used herein includes any Warrants into which this Warrant may be
divided or exchanged. Upon receipt by the Company or its warrant agent, if any,
of evidence satisfactory to it of the loss, theft, destruction or mutilation of
this Warrant, and (in the case of loss, theft or destruction) of reasonably
satisfactory indemnification, and upon surrender and cancellation of this
Warrant, if mutilated, the Company will execute and deliver a new Warrant of
like tenor and date.

         (5) RIGHTS OF THE HOLDER. The Holder shall not, by virtue hereof, be
entitled to any rights of a stockholder in the Company, either at law or equity,
and the rights of the Holder are limited to those expressed in the Warrant and
are not enforceable against the Company except to the extent set forth herein
and in any warrant agreement entered into by and between the Company and a
warrant agent with respect to the Warrants. In the event the Company enters into
a warrant agreement with a warrant agent, the terms of the Warrant shall be
embodied in the warrant agreement; and the acceptance of this Warrant by the
Holder shall be deemed consent by the Holder for the Company to enter into any
such warrant agreement, upon such terms and conditions mutually agreeable
between the Company and any such warrant agent, provided such warrant agreement
does not adversely affect any of the rights of the Holder, as set forth in this
Warrant.

         (6) ANTI-DILUTION PROVISIONS. (a) After each adjustment of the Exercise
Price pursuant to this Section (6), the number of shares of Common Stock
purchasable upon the exercise of the Warrant shall be the number of Warrant
Shares receivable upon exercise thereof prior to such adjustment multiplied by a
fraction the numerator of which shall be the original Exercise Price as defined
above and the denominator of which shall be such adjusted Exercise Price.:

             (b) In case the Company shall hereafter (A) pay a dividend or make
a distribution on its Common Stock in shares of its capital stock (whether
shares of Common Stock or of capital stock of any other class), (B) subdivide
its outstanding shares of Common Stock, (C) combine its outstanding shares of
Common Stock into a smaller number of shares, or (D) issue by reclassification
of its shares of Common Stock any shares of capital stock of the Company, the
Exercise Price in effect immediately prior to such action shall be adjusted so
that the Holder of any Warrant thereafter exercised shall be entitled to receive
the number of Warrant Shares which the


                                     - 5 -
<PAGE>


Holder would have owned immediately following such action had such Warrant been
exercised immediately prior thereto. An adjustment made pursuant to this
subsection shall become effective immediately after the record date in the case
of a dividend and shall become effective immediately after the effective date in
the case of a subdivision, combination or reclassification.

               (c) No adjustment in the Exercise Price shall be required to be
made unless such adjustment would require an increase or decrease of at least
$.01; provided, however, that any adjustments which by reason of this subsection
are not required to be made shall be carried forward and taken into account in
any subsequent adjustment. All calculations under this Section (6) shall be made
to the nearest cent or to the nearest one-one hundredth of a share, as the case
may be, but in no event shall the Company be obligated to issue fractional
shares upon the exercise of any Warrant.

               (d) The provisions of this Section 6 shall not apply to any
Common Stock issuable: (i) to any person pursuant to any stock option, stock
purchase, stock purchase or similar plan or arrangement for the benefit of the
Company's employees, consultants or directors or (ii) pursuant to options,
warrants, conversion rights, and rights to acquire Common Stock in existence on
the date of issuance hereof.

               (e) In case of any reclassification or change of outstanding
shares of Common Stock issuable upon exercise of the Warrants (other than a
change in par value or from 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 case of any
consolidation or merger of the Company with or into another corporation (other
than a merger with a Subsidiary in which merger the Company is the continuing
corporation and which does not result in any reclassification or change of the
then outstanding shares of Common Stock


                                     - 6 -
<PAGE>


or other capital stock issuable upon exercise of the Warrants other than a
change in par value or from par value to no par value or from no par value to
par value) or in the case of any sale or conveyance to another corporation of
the property of the Company as an entirety or substantially as an entirety,
then, as a condition of such reclassification, change, consolidation, merger,
sale or conveyance, the Company, or such successor or purchasing corporation, as
the case may be, shall make lawful and adequate provision whereby the Holder of
the Warrant shall have the right thereafter to receive on exercise of such
Warrant the kind and amount of shares of stock and other securities and property
receivable upon such reclassification, change, consolidation, merger, sale or
conveyance by a holder of the number of shares of Common Stock issuable upon
exercise of such Warrant immediately prior to such reclassification, change,
consolidation, merger, sale or conveyance. Such provisions shall include
provision for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided elsewhere in this Section (6). The above
provisions of this Section (6) shall similarly apply to successive
reclassifications and changes of shares of Common Stock and to successive
consolidations, mergers, sales or conveyances.

               (f) Before taking any action which would cause an adjustment
reducing the Exercise Price below the then par value of the shares of Common
Stock issuable upon exercise of the Warrants, the Company will take any
corporate action which may, in the opinion of its counsel, be necessary in order
that the Company may validly and legally issue fully paid and non-assessable
shares of such the Company at such adjusted Exercise Price.

               (g) Upon any adjustment of the Exercise Price and any increase or
decrease in the number of shares of Common Stock purchasable upon the exercise
of this Warrant, the Company


                                     - 7 -
<PAGE>


promptly shall give written notice thereof to the Holder, which shall state the
Exercise Price resulting from such adjustment and increase or decrease, if any,
in the number of shares of Common Stock purchasable at such price upon the
exercise of this Warrant, setting forth in reasonable detail the method of
calculation and the facts upon which such calculation is based.

               (h)  If at any time:

                       (i)    the Company shall declare any cash dividend upon
                              its Common Stock;

                       (ii)   the Company shall declare any dividend upon its
                              Common Stock payable in stock (other than a
                              dividend payable solely in shares of Common Stock
                              or make any special dividend or other distribution
                              to the holders of its Common stock;

                       (iii)  there shall be any consolidation or merger of the
                              Company with another corporation, or a sale of all
                              or substantially all of the Company's assets to
                              another corporation; or

                       (iv)   there shall be a voluntary or involuntary
                              dissolution, liquidation or winding-up of the
                              Company;

then, in any one or more of said cases, the Company shall give the Holder (A) at
least ten (10) calendar days' prior written notice of the date on which the
books of the Company shall close or a record date shall have occurred for such
dividend or distribution or for determining rights to vote in respect of any
such consolidation, merger, sale, dissolution, liquidation or winding-up, and
(B) in the case of any such consolidation, merger, sale, dissolution,
liquidation or winding-up, at least ten (10) calendar days' written notice of
the date when the same shall take place. Any notice given in accordance with
clause (A) above shall also specify, in the case of any such dividend or


                                     - 8 -
<PAGE>


distribution, the date on which the holders of Common Stock shall be entitled
thereof. Any notice given in accordance with clause (B) above shall also specify
the date on which the holders of Common Stock shall be entitled to exchange
their Common Stock for securities or other property deliverable upon such
consolidation, merger, sale, dissolution, liquidation or winding-up, as the case
may be.

         (7) ADJUSTMENT OF WARRANT SHARES. In the event that the shares of
common stock of the Company underlying the Note (the "Conversion Shares") shall
be adjusted in accordance with the terms of Section (8) of the Note, then the
Warrant Shares issuable upon the exercise of this Warrant shall also be adjusted
so that the number of Warrant Shares into which this Warrant converts shall
equal 10% of the aggregate amount of the Conversion Shares issuable upon the
conversion of the Note after giving effect to such adjustment. This Section (7)
shall similarly apply to any successive adjustments in the Conversion Shares in
accordance with Section (8) under the Note. This Section (7) shall terminate
upon the conversion of the Note.

         (8) INVESTMENT REPRESENTATION. By accepting this Warrant, the Holder
acknowledges that it has been advised by the Company that this Warrant and the
Warrant Shares underlying this Warrant have not been registered under the
Securities Act of 1933, as amended (the "Act"), and that this Warrant is being
issued on the basis of the statutory exemption provided by section 4(2) of the
Act relating to transactions by an issuer not involving any public offering.
Holder hereby represents and warrants to the Company that (I) it is acquiring
this Warrant for its own account, for investment purposes only and not with a
view toward the distribution or resale thereof, (ii) it is a sophisticated
investor and had access to the same kind of information which would be available
in a registration statement filed under the Act, and (iii) it understands that
it

                                     - 9 -
<PAGE>


may not sell or otherwise dispose of this Warrant in the absence of either a
registration statement under the Act or an exemption from the registration
provisions thereunder and in accordance with the transfer provisions set forth
in this Section 10 of this Warrant.

         (9) REGISTRATION RIGHTS. The Company hereby grants the Holder the right
to "piggy back" the Warrant Shares on each Registration Statement for the sale
of Common Stock filed by the Company (or any securities of a successor company
of the Company) at the Company's cost and expense (except those incurred by the
Holder for legal fees and commissions). In this connection, the Company shall
give the Holder at least 30 days' prior notice of its intent to file a
Registration Statement. The Company shall use its best efforts to keep any
Registration Statement onto which Holder has "piggy backed" his shares effective
for a period of not less than 180 days from the date whereby the Holder is first
entitled to sell thereunder, or such shorter period terminating when the Holder
has sold all of his shares. Such "piggy back" rights are subject to standard
underwriters' approval and holdback, whereby the Holder's rights to sell in an
initial public offering may be limited pro rata with the other stockholders and
shall not apply to any Warrant Shares that can be sold under SEC Rule 144. For
purposes of this Section (9), the term Registration Statement shall mean any
registration statement for the sale of common stock or other securities filed by
the Company or any selling shareholder or filed by any successor entity (in the
case of merger, reclassification, change, consolidation, sale or conveyance of
the Company) under the Act (except for a Registration Statement on Form S-4,
Form S-8 or any successor form thereto), which shall include, but not be limited
to, any Registration Statement filed by Healthcore Medical Solutions, Inc.
("Healthcore") in connection with, relating to or subsequent to the effective
date of the merger of the Company into Healthcore (the "Merger") as contemplated
by that certain


                                     - 10 -
<PAGE>


Letter of Intent, dated April 27, 1999, by and between the Company and/or
Healthcore;

              (i) The Company shall also grant to Holder such additional
"piggyback" rights and demand registration rights relative to the Warrant Shares
as shall be granted and included in a subsequent warrant that may be granted to
Holder.

         (10) TRANSFER. (i) The Holder acknowledges that it has been informed by
the Company of, or is otherwise familiar with, the nature of the limitations
imposed by the Act and the rules and regulations thereunder on the transfer of
this Warrant and the Warrant Shares. In particular, the Holder agrees that no
sale, assignment, or transfer of this Warrant shall be valid or effective, and
the Company shall not be required to give any effect to any such sale,
assignment, or transfer, unless (A) the sale, assignment, or transfer of this
Warrant or the Warrant Shares is registered under the Act, it being understood
that this Warrant or the underlying Warrant Shares is not currently registered
under the Act and that the Company has no obligation to register this Warrant
and is only obligated to register the Warrant Shares to the extent set forth in
Section 9 of this Warrant, (B) this Warrant or the underlying Warrant Shares are
sold, assigned or transferred in accordance with all of the requirements and
limitations of Rule 144 under the Act, it being understood that Rule 144 is not
available at the present time for the sale of the Warrant or underlying Warrant
Shares and that there can be no assurance that Rule 144 will be available at any
time in the future, or (C) such sale, assignment, or transfer is otherwise
exempt from registration under the Act. The Holder and each transferee hereof
further agrees that in any distribution of this Warrant or the underlying
Warrant Shares is proposed to be made by them otherwise than by delivery of a
prospectus meeting the requirements of Section 10 of the Act, such action shall
be taken only after submission to the Company of an opinion of counsel,
reasonably


                                     - 11 -
<PAGE>


satisfactory in form and substance to the Company's counsel, to the effect that
the proposed distribution will not be in violation of the Act or applicable
state law.

                  (ii) Prior to any such proposed transfer, and as a condition
thereto, if such transfer is not made pursuant to an effective registration
statement under the Act, the Holder will, if requested by the Company, deliver
to the Company (i) an investment covenant signed by the proposed transferee,
(ii) an agreement by such transferee, that such transferee will be bound by the
terms of this Warrant and that the restrictive investment legend set forth above
be placed on the certificate or certificates representing the securities
acquired by such transferee, and (iii) an agreement by such transferee that the
Company may place a "stop transfer order" with its transfer agent or registrar.

                  (iii) Except as specifically restricted hereby, this Warrant
and the Warrant Shares issued hereunder may be transferred by the Holder in
whole or in part at any time or from time to time. Upon surrender of this
Warrant certificate to the Company or at the office of its stock transfer agent,
if any, with the Assignment Form annexed hereto duly executed and funds
sufficient to pay any transfer tax, and upon compliance with the foregoing
provisions, the Company shall without charge, execute and deliver a new Warrant
certificate in the name of the assignee named on such instrument of assignment,
and this Warrant certificate shall promptly be canceled. An assignment,
transfer, pledge, hypothecation or other disposition of this Warrant attempted
contrary to the provisions of this Warrant, or any levy of execution, attachment
or other process attempted upon this warrant, shall be null and void and without
effect.

         (11) NOTICES. All notices and other communications which are required
or may be given under this Warrant shall be in writing and shall be deemed to
have been duly given when


                                     - 12 -
<PAGE>

such party shall have specified by notice to the other party hereto. If notice

receipt requested, the return receipt shall be conclusive evidence of the notice
having been mailed on the date set forth.

         (12) DEFINITION. The "Current Market Price" per share of Common Stock
on any date shall be deemed to be the average of the daily closing prices for
the thirty (30) consecutive trading days immediately preceding the date in
question. The closing price for each day shall be the last reported sales price
regular way or, in case no such reported sale takes place on such day, the
closing bid price regular way, in either case on the principal national
securities exchange (including, for purposes hereof, the NASDAQ Stock Market,
Inc. ("NASDAQ") on which the shares of Common Stock are listed or admitted to
trading, or, if the shares of Common Stock are not listed or admitted to trading
on any national securities exchange, the highest reported bid price for the
Common Stock as furnished by the National Association of Securities Dealers,
Inc. (the "NASD") or a similar organization if the NASD is no longer reporting
such information (including for purposes hereof NASDAQ). If on any such date the
shares of Common Stock are not listed or admitted to trading on any national
securities exchange and is not quoted by NASDAQ or any similar organization, the
fair value of a share on such date, as determined in good faith by the Board of
Directors of the Company, whose determination shall be conclusive, shall be
used.

be changed orally, but only by an agreement in writing signed by the party
against whom any waiver, change, amendment, modification or discharge is sought,

              (c) Qualification. The Company is duly licensed or qualified and
in good standing as a foreign corporation in each jurisdiction wherein the
nature of the business transacted by it or the nature of the property owned or

consists of 10,000,000 shares of common stock, no par value per share (the

Company would be reduced to less than an amount equal to the remaining
indebtedness outstanding under this Note.

              (f) Related Transactions. The Company will not engage in any
transaction of any kind or nature with any affiliate of the Company unless such
transaction, or in the case of a course of related or similar transactions or

a party or by which it or any of its assets may be bound; and (ii) the execution
and delivery of this Note and compliance with the provisions hereof shall not
violate any provision of law applicable to the Company nor shall the same
conflict with or result in a breach of any of the terms, conditions or
provisions of, or constitute a default under, the certificate of incorporation
or by-laws of the Company or result in the breach of, constitute any default
under, or conflict with the terms of any indenture, mortgage, agreement or other
instrument to which the Company is party or by which they or any of their assets
may be bound or result in the creation or imposition of any Lien upon any of the
Collateral, other than for the Security Interest granted hereunder.

              (m) Consents. No consent, approval, order, authorization of, or
registration, qualification or filing with, any governmental authority or any

otherwise) of the Company.

              (o) Title. The Company is the sole owner of, and has good title
to, the Collateral, free and clear of any Lien, except for the Security Interest

an assignment for the benefit of creditors, or the admission by either of them
in writing of the inability to pay their debts generally as they become due, or
the taking of corporate action by the Company in furtherance of any such action.

              (c) Acceleration on Other Indebtedness, etc.

principal of or interest on any other indebtedness for borrowed money owed by
the Company by any holder of any such indebtedness.; or

                                       6
<PAGE>

                  (ii) Payment of any indebtedness of the Company in excess
of $100,000 prior to the payment in full of the Principal Amount or redemption
premium of the Note.

Section 6.    Remedies Upon Default.

              (a) Acceleration. Upon an Event of Default and at any time during
the continuation thereof, the Holder, by notice given to the Company, may
declare the entire unpaid Principal Amount, plus any redemption premium that
would be paid in full on the date of such declaration of this Note then
outstanding to be due and payable immediately, and upon any such declaration the
same shall become and be due and payable immediately, anything herein contained
to the contrary notwithstanding.

              (b) Remedies Regarding Security Interest in Collateral. Upon the
occurrence of any Event of Default, the Holder shall have the following
additional rights and remedies:

                  (i)  All rights and remedies provided by law, including,
without limitation, those provided by the Uniform Commercial Code as in effect
in the State of California from time to time (the "UCC").

                  (ii) The right to take possession of the Collateral and,
in addition thereto, the right to enter upon any premises on which the
Collateral or any part thereof may be situated, without notice, and remove the
same therefrom. The Holder may require the Company to make the Collateral (to
the extent the same is moveable) available to the Holder at a place to be
designated by the Holder which is reasonably convenient to both parties at the
Company's expense. Unless the Collateral threatens to decline speedily in value
or is of a type customarily sold on a recognized market, the Holder will give
the Company at least two (2) days' prior written notice at the address of the
Company set forth above (or at such other address or addresses as the Company
shall specify in writing to the Holder) of the time and place of any public sale
thereof or of the time after which any private sale or any other intended
disposition thereof is to be made. Any such notice shall be deemed to meet any
requirement hereunder or under any applicable law (including the UCC) that
reasonable notification be given of the time and place of such sale or other
disposition. After deducting all reasonable costs and expenses of collection,
storage, custody, sale or other disposition and delivery (including reasonable
legal costs and attorneys' fees, expenses and disbursements) and all other
charges against the Collateral, the remaining proceeds of any such sale or
disposition shall be applied to the payment of the Secured Indebtedness in such
order of priority as the Holder shall determine and any surplus shall be
returned to the Company or to any person or party lawfully entitled thereto. In
the event the proceeds of any sale, lease or other disposition of the Collateral
hereunder are insufficient to pay all of the Secured Indebtedness in full, the
Company will be liable for the deficiency, together with interest thereon at the
highest rate of interest provided in this Note, and the costs and expenses of
collection of such deficiency, including (to the extent permitted by law),
without limitation, reasonable attorneys' fees, expenses and disbursements.

              (c) Proceedings and Actions. During the continuation of any Event
of Default, the Holder may institute such actions and proceedings in law or
equity as it shall deem expedient for the protection of its rights and may
prosecute and enforce its claims against all assets of the Company, and in
connection with any such action or proceeding shall be entitled to

                                       7
<PAGE>

receive from the Company payment of the Principal Amount of this Note plus, as
applicable, the redemption premium referred to in subsection (a) above, to the
date of payment plus reasonable expenses of collection including, without
limitation, reasonable attorneys' fees and expenses. All rights and remedies
available to the Holder pursuant to the provisions of this Note, applicable law
and otherwise are cumulative, not exclusive and are enforceable alternatively
and/or concurrently by Holder.

Section 7.    Automatic Conversion.

              This Note shall automatically convert into 233,135 fully
registered and freely tradable shares of Common Stock immediately prior to the
effective time of the Merger (the "Conversion Shares") which shall be equal to
4.74% of the total shares of capital stock of the Company outstanding (on a
fully diluted basis) prior to the effective date of the Merger.

Section 8.    Anti-Dilution Provisions.

              In the event of any of the foregoing circumstances, the number of
Conversion Shares shall be subject to adjustment as follows:

              (a) In case the Company shall hereafter (i) pay a dividend or make
a distribution on its Common Stock in shares of its capital stock (whether
shares of Common Stock or of capital stock of any other class); (ii) subdivide
its outstanding shares of Common Stock; (iii) combine its outstanding shares of
Common Stock into a smaller number of shares; (iv) issue by reclassification of
its shares of Common Stock any shares of capital stock of the Company; or (v)
issue additional shares of its common stock, which dividend, subdivision,
combination, reclassification or issuance shall result in the aggregate amount
of the Conversion Shares being less than 4.74% of the total issued and
outstanding shares of the Company (on a fully diluted basis) after giving effect
to (i), (ii), (iii), (iv) or (v), as the case may be, then the number of
Conversion Shares issuable to Holder upon the conversion of this Note shall be
adjusted so that Holder shall receive such number of Conversion Shares as shall
equal 4.74% of the total issued and outstanding shares of the Company (on a
fully diluted basis). An adjustment made pursuant to this subsection shall
become effective immediately after the record date in the case of a dividend,
subdivision, combination, reclassification, or issuance of additional stock of
the Company.

              (b) All calculations under this Section 8 shall be made to the
nearest one-one hundredth of a share but in no event shall the Company be
obligated to issue fractional shares hereunder.

              (c) In case of any reclassification or change of the Conversion
Shares (other than a change in par value or from 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 case of any consolidation or merger of the Company with or into another
corporation (other than a merger with a Subsidiary in which merger the Company
is the continuing corporation and which does not result in any reclassification
or change of the then outstanding shares of Common Stock or other capital stock
issuable upon the conversion of this Note other than a change in par value or
from par value to no par value or from no par value to par value) or in the case
of any sale or conveyance to

                                       8
<PAGE>

another corporation of the property of the Company as an entirety or
substantially as an entirety, then, as a condition of such reclassification,
change, consolidation, merger, sale or conveyance, the Company, or such
successor or purchasing corporation, as the case may be, shall make lawful and
adequate provision whereby the Holder of the Note shall have the right
thereafter to receive on the conversion thereof the kind and amount of shares of
stock and other securities and property receivable upon such reclassification,
change, consolidation, merger, sale or conveyance by a holder equal to 4.74% of
the total outstanding Shares of the Company. Such provisions shall include
provision for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided elsewhere in this Section (8). The above
provisions of this Section 8 shall similarly apply to successive
reclassifications and changes of shares of Common Stock and to successive
consolidations, mergers, sales or conveyances;

              (d) Notwithstanding the foregoing, the Company shall, from time
to time, adjust the number of Conversion Shares, if necessary, so that the
Holder hereof shall receive such number of Conversion Shares as shall equal
4.74% of the total issued and outstanding capital stock of the Company (on a
fully diluted basis) immediately prior to the Effective Date of the Merger;

              (e) Before taking any action which would cause an adjustment in
the number of Conversion Shares issuable hereunder, the Company will take any
corporate action which may, in the opinion of its counsel, be necessary in order
that the Company may validly and legally issue fully paid and non-assessable
shares of the Company at such adjusted Exercise Price.

<PAGE>

144 sales will be available at any time in the future, or (iii) such sale,
assignment, or transfer is otherwise exempt from registration under the Act. The
Holder and each transferee hereof further agrees that if any distribution of the
Note is proposed to be made by them otherwise than by delivery of a prospectus
meeting the requirements of Section 10 of the Act, such action shall be taken
only after submission to the Company of an opinion of counsel, reasonably
satisfactory in form and substance to the Company's counsel, to the effect that
the proposed distribution will not be in violation of the Act or of applicable
state law. Furthermore, it shall be a condition to the transfer of the Note that

                              TERMINATION AGREEMENT

                  TERMINATION AGREEMENT (the "Agreement") made as of this ___
day of July, 1999, by and among HealthCore Medical Solutions, Inc., a Delaware

                              W I T N E S S E T H:

                  WHEREAS, HealthCore and the Participating Escrow Shareholders
are parties to that certain Amended and Restated Escrow Agreement (the "Escrow
Agreement"), dated as of July 31, 1997, among HealthCore, the Participating
Escrow Shareholders, the other stockholders of HealthCore who are signatories to

and, together with the Participating Escrow Shareholders, collectively, the
"Escrow Shareholders") and American Stock Transfer & Trust Company (the "Escrow
Agent"), pursuant to which certain of the shares of Common Stock of HealthCore
(collectively, the "HealthCore Common Stock") owned beneficially and of record
by the Escrow Shareholders (such shares being collectively referred to as the
"Escrow Shares") are held in escrow; and


<PAGE>


                  WHEREAS, HealthCore is a party to that certain Agreement and
Plan of Merger, dated July 1, 1999, between HealthCore and Adatom, Inc.
("Adatom"), a California corporation, which contemplates, among other things,
the merger of Adatom with and into HealthCore (the "Merger"); and

                  WHEREAS, in connection with the Merger, and subject to the
terms and conditions of this Agreement, HealthCore and the Participating Escrow
Shareholders desire to terminate the Escrow Agreement as to each Participating
Escrow Shareholder, and, in connection therewith, cancel four (4) Escrow Shares
for every five (5) Escrow Shares (i.e., eighty (80%) percent of the Escrow
Shares) owned beneficially and of record by each of the Participating Escrow
Shareholders (the remaining shares held by the Participating Escrow Shareholders
following such cancellation being collectively referred to as the "Released
Shares"); and

                  WHEREAS, the affirmative vote of the holders of two-thirds
(2/3) of the outstanding shares of HealthCore Common Stock entitled to vote with
respect to the adoption and approval of this Agreement and the transactions
contemplated hereby, excluding the vote of the shares of HealthCore Common Stock
held by the Participating Escrow Shareholders (such vote being the "Required

<PAGE>


                  NOW, THEREFORE, HealthCore and the Participating Escrow
Shareholders hereby agree as follows:

                                    ARTICLE 1
                              SURRENDER OF SHARES;
               TERMINATION OF ESCROW AGREEMENT; GRANT OF PROXIES

                  1.1 Surrender of Shares. Subject to the terms and conditions
of this Agreement, and in reliance upon the representations, warranties and
covenants contained herein, on the Termination Closing Date (as defined in
Section 5.1 hereof), the number of Escrow Shares set forth opposite each
Participating Escrow Shareholder's name on Schedule 1.1 hereto, constituting
eighty (80%) percent of the Escrow Shares owned beneficially and of record by
such Participating Escrow Shareholder, shall be and be deemed cancelled, without
the necessity of any further action on the part of the Participating Escrow
Shareholder, and such Participating Escrow Shareholders shall have no rights of
any kind or nature in or to such Escrow Shares.

                  1.2 Termination of Escrow Agreement.

                         (a) Notwithstanding anything in the Escrow Agreement to
the contrary, and subject to HealthCore's receipt of the Required Stockholder
Vote, on the Termination Closing Date the Escrow Agreement shall be deemed
terminated, and of no further force or effect, with respect to the Participating
Escrow Shareholders, only, and all of the Released Shares shall be distributed
to


                                       3
<PAGE>


the Participating Escrow Shareholders, without the restrictive legend described
in Section 9(a) of the Escrow Agreement that is currently contained on the
certificates representing the Escrow Shares shall be deleted. By the execution
of this Agreement, each Participating Escrow Shareholder authorizes and directs
the Escrow Agent under the Escrow Agreement to deliver all certificates for the
Escrow Shares to HealthCore, at a location in New York City specified by
HealthCore upon receipt from HealthCore of a letter verifying that the Required
Stockholder Vote has been obtained. Upon its receipt thereof, HealthCore shall,
within ten (10) business days thereafter, deliver to each Participating Escrow
Shareholders the number of Released Shares to which such Participating Escrow
Shareholder is entitled as more particularly set forth on Schedule 1.1 hereto.

                         (b) Notwithstanding anything contained herein to the
contrary, this Agreement shall be binding upon, and shall inure to the benefit
of only those parties who have executed this Agreement. The Non-Participating
Escrow Shareholders shall have no rights, of any kind or nature, under this
Agreement, and such Non-Participating Escrow Shareholders and the shares of
HealthCore Common Stock owned by the Non-Participating Escrow Shareholders that
are held in escrow, shall remain subject to the all of terms and conditions of
the Escrow Agreement.

<PAGE>


                  1.3 Grant of Proxies. Contemporaneously with the execution
hereof, each of the Participating Escrow Shareholders shall execute and deliver
to HealthCore an irrevocable proxy (collectively, the "Voting Proxies")
appointing Neal J. Polan ("Polan"), the Chairman of the Board and Chief
Executive Officer of HealthCore, as proxy to vote all of the shares of
HealthCore Common Stock owned beneficially and of record by such Participating
Escrow Shareholder, including, without limitation, the Released Shares, for a
period expiring on the earliest of (a) the first date by which both (i) the
closing of the transactions contemplated by the Merger Agreement shall have
occurred ("Merger Closing"), and (ii) HealthCore shall have received the
Required Stockholder Vote, (b) the termination of the agreements contained in
the Merger Agreement, and (c) with respect to those shares of HealthCore Common
Stock other than the Escrow Shares sold by the Participating Escrow
Shareholders, HealthCore's receipt of notice of the consummation of the sale of
such shares of HealthCore Common Stock.


                                   ARTICLE 2
                         REPRESENTATIONS AND WARRANTIES
                      OF PARTICIPATING ESCROW SHAREHOLDERS

                  Each Participating Escrow Shareholder represents and warrants
to HealthCore as follows:


                                       5
<PAGE>


                  2.1 Authority. Such Participating Escrow Shareholder has the
right, power, authority and legal capacity to enter into and perform such
Participating Escrow Shareholder's obligations under this Agreement and to
consummate the transactions contemplated hereby to be performed by such
Participating Escrow Shareholder, and this Agreement has been duly executed and
delivered by such Participating Escrow Shareholder and is a valid and binding
agreement of such Participating Escrow Shareholder enforceable against such
Participating Escrow Shareholder in accordance with its terms, except as may be
limited by applicable bankruptcy, insolvency or similar laws affecting
creditors' rights generally or the availability of equitable remedies.

                  2.2 Title to the Escrow Shares. Such Participating Escrow
Shareholder owns, beneficially and of record, the number of Escrow Shares set
opposite the name of such Participating Escrow Shareholder on Schedule 1.1, free
and clear of any and all liens, claims or encumbrances, of any kind or nature,
and upon delivery to HealthCore of the certificate or certificates evidencing
such Escrow Shares, duly endorsed for transfer to HealthCore, HealthCore will
acquire good, valid, indefeasible and marketable title thereto, free and clear
of any and all liens, claims or encumbrances, of any kind or nature.

                  2.3 Examination of Documents. HealthCore has delivered to such
Participating Escrow Shareholder, and such Participating Escrow Shareholder has
examined, the Annual Report of Form 10-KSB of HealthCore for the fiscal year



                                       6
<PAGE>


ended September 30, 1998 (the "1998 Form 10-KSB"), HealthCore's Quarterly Report
on Form 10-QSB for each of the quarters ended December 31, 1998 and March 31,
1999, including the financial statements contained therein, and HealthCore's
Current Report on Form 8-K, filed with SEC on July 9, together with the exhibits
thereto, and has had the opportunity to discuss HealthCore's operations with
HealthCore's officers and employees.

                  2.4 Acknowledgment. Each of the Participating Escrow
Shareholders acknowledges that in the event the Merger is not consummated, and
HealthCore continued its current business activities as more particularly
described in HealthCore's most recent 10QSB, it is highly unlikely as of the
date hereof that the conditions in the Escrow Agreement for release of the
Escrow Shares would be satisfied prior to the last possible date for the
attainment thereof, and thus each Participating Escrow Shareholder may be
required to forfeit all of his or her Escrow Shares pursuant to the terms of the
Escrow Agreement. Each Participating Escrow Shareholder further acknowledges
that, in light of the foregoing, he or she carefully considered whether or not
to enter into this Agreement and has concluded that to do so is prudent and
provides the best opportunity at this time to realize ownership of even a
portion of the Escrow Shares.

                            WARRANTIES OF HEALTHCORE

                  HealthCore represents and warrants to the Participating Escrow
Shareholders as follows:

                  3.1 Authority. The Board of Directors of HealthCore has

obligations hereunder and to consummate the transactions contemplated hereby.
This Agreement has been duly and validly executed and delivered by HealthCore
and constitutes a valid and binding obligation of HealthCore enforceable against
HealthCore in accordance with its terms, subject to HealthCore's receipt of the
Required Stockholder Vote.

                      [LETTERHEAD OF KAUFMAN BROS., L.P.]

                                  July 26, 1999

Mr. Neal J. Polan
Chairman & CEO
HealthCore Medical Solutions, Inc.
405 Lexington Avenue
50th Floor
New York, NY  10174

Dear Mr. Polan:

     You have informed us that HealthCore Medical Solutions, Inc. (the
"Company") has under consideration a transaction pursuant to which the Company
would engage in a business combination (the "Transaction") with Adatom, Inc.
("Target") as a result of which the Company's current shareholders would own
approximately 22.5% of the common stock (subject to adjustment in certain
circumstances) of the combined entity after the Transaction. The Transaction is
subject to, among other things, the approval of the Board of Directors and the
shareholders of the Company.

     In connection with its review and analysis of the Transaction, the Board of
Directors of the Company has requested Kaufman Bros., L.P. ("Kaufman") to advise
it and to render a written opinion (the "Opinion") as to the fairness to the
shareholders of the Company from a financial point of view of the consideration
to be received in the Transaction. Kaufman agrees to conduct such financial
review of the Company and Target, and their respective businesses and operations
as Kaufman shall deem appropriate and feasible. The Company agrees to provide or
cause to be provided to Kaufman such financial and other information concerning
the Company as Kaufman may request, and to use its best efforts to obtain
financial and other information concerning the Target as Kaufman may request, in
connection with the services performed or to be performed hereunder. In
rendering the Opinion, Kaufman will be assuming and relying, without independent
verification, upon the accuracy and completeness of the financial and other
information used by it in arriving at its Opinion.

     In consideration for the services to be performed by Kaufman pursuant to
this agreement, the Company agrees to pay Kaufman a fee of $65,000, of which
$32,500 is payable in cash on the date of this letter and $32,500 is payable in
cash on the date Kaufman delivers the Opinion. In addition, Kaufman shall be
reimbursed by the Company for its reasonable out-of-pocket expenses (including
legal fees and disbursements) in connection with its services hereunder, limited
to $5,000. Such fees and reimbursements shall be payable irrespective of either
the conclusions reached in the Opinion or the consummation of the Transaction.

     Kaufman will consent to a description and inclusion of the Opinion in a
proxy statement to be used in connection with a meeting (if needed) of the
Company's shareholders to be held for the purpose of voting on the Transaction
and to references to Kaufman in such proxy statement provided that any such
description is acceptable to Kaufman. In addition to the meeting of
stockholders, or otherwise in connection with providing information to
stockholders regarding the Transaction, the Company may provide to stockholders
a copy of the Opinion in the form delivered to the Company's Board of Directors.
Except as otherwise provided above, the Opinion is solely for the use and
benefit of the Company and shall not be described publicly or made available to
third parties without Kaufman's prior approval, except as otherwise required by
law.

     The Company agrees to indemnify and hold Kaufman harmless from and against
any losses, claims, damages or liabilities (or actions, including securityholder
actions, in respect thereof) related to or arising out of Kaufman's engagement
hereunder or its role in connection herewith, and will reimburse Kaufman for all
reasonable expenses (including reasonable counsel fees) as they are incurred by
Kaufman in connection with investigating, preparing for or defending any such
action or claim, whether or not in connection with pending or threatened
litigation in which Kaufman is a party. The Company will not, however, be
responsible for any claims, liabilities, losses, damages or expenses which are
finally judicially determined to have resulted from the bad faith, willful
misconduct or gross negligence of Kaufman. The Company also agrees that Kaufman
shall not have any liability (whether direct or indirect, in contract or tort or
otherwise) to the Company for or in connection with such engagement, except for
any such liability for losses, claims, damages, liabilities or expenses incurred
by the Company that result from the bad faith, willful misconduct or gross
negligence of Kaufman. In the event that the foregoing indemnity is unavailable
(except by reason of the bad faith, willful misconduct or gross negligence of
Kaufman), then the Company shall contribute to amounts paid or payable by
Kaufman in respect of its losses, claims, damages and liabilities in such
proportion as appropriately reflects the relative benefits received by, and
fault of, the Company and Kaufman in connection with the matters as to which
such losses, claims, damages or liabilities relate and other equitable
considerations; provided, however, that in no event shall the amount to be
contributed by Kaufman exceed the amount of the fee actually received by
Kaufman. The foregoing shall be in addition to any rights that Kaufman or any
other indemnified person may have at common law or otherwise and shall extend to
and inure to the benefit of any director, officer, employee, agent or
controlling person of Kaufman.

     This Agreement may not be amended or modified except in writing and shall
be governed by and construed in accordance with the laws of the State of New
York.

                       1999 INCENTIVE AND NON-QUALIFIED

                               STOCK OPTION PLAN

                                      OF

                      HEALTHCORE MEDICAL SOLUTIONS, INC.


         1. Purpose of Plan. The purpose of this 1999 Incentive and
Non-Qualified Stock Option Plan ("Plan") is to further the growth and
development of HealthCore Medical Solutions, Inc. (the "Company") and its
subsidiaries by encouraging selected employees, consultants, officers,
directors, independent contractors and other persons who contribute and are
expected to contribute materially to the success of the Company or any
subsidiary to obtain a proprietary interest in the Company through the ownership
of stock, thereby providing such persons with an added incentive to promote the
long-term financial interests of the Company and enhancement of long-term
stockholder return. The Plan is further intended to afford the Company and any
subsidiary a means of attracting to its service persons of outstanding ability.
Unless otherwise defined elsewhere in the Plan, capitalized terms used herein
are defined in Section 17 hereof.

         2. Stock Subject to the Plan. An aggregate of 1,400,000 shares of
Common Stock, $.01 of par value per share ("Common Stock") of the Company,
subject to adjustment or change pursuant to Section 10 hereof, shall be reserved
for issuance upon the exercise of options which may be granted from time to time
in accordance with the Plan ("Options"). Such shares may be, in whole or in
part, authorized but unissued shares or issued shares which have been reacquired
by the Company as the Compensation Committee ("Committee") of the Board of
Directors ("Board") shall from time to time determine. If, for any reason, an
Option shall lapse, expire or terminate without having been exercised in full,
the unpurchased shares covered thereby shall again be available for purposes of
the Plan. If, for any reason, any shares of Common Stock purchased upon exercise
of an Option are repurchased by the Company, such shares shall again be
available for purposes of the Plan. If the exercise price of an Option granted
under the Plan is satisfied by tendering shares of Common Stock, only the number
of shares of Common Stock issued, net of the shares of Common Stock so tendered,
shall be deemed delivered for purposes of calculating the maximum number of
shares of Common Stock reserved for issuance under the Plan.

         3. Administration. The authority to manage and control the operation
and administration of the Plan shall be vested in the Committee which shall at
all times consist of two or more Board members. The Board shall have power at
any time to fill vacancies in, to change the membership of, or to discharge the
Committee. The Committee shall select one of its members as its chairman and
shall hold its meetings at such time and at such places as it shall deem
advisable. A majority of the Committee shall constitute a quorum and such
majority shall determine its action. Any action may be taken without a meeting
by written consent of all the members of the Committee. The Committee shall keep
minutes of its proceedings and shall report the same to the Board at the next
succeeding meeting of the Board. The members of the Committee shall be "outside
directors" as defined in the regulations under Section 162(m)

<PAGE>

of the Internal Revenue Code of 1986, as amended (the "Code"), and
"non-employee directors" as defined by Regulation 240.16b-3 under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"). The
Committee's authority shall be subject to the following:

         (a) subject to the provisions of the Plan, the Committee shall have
authority in its sole discretion to select from among those persons eligible
to receive Options under the Plan those persons who shall receive Options, to
determine the time or times at which Options shall be granted and the number
of shares of Common Stock to be subject to each such Option; to establish the
terms, conditions, performance criteria, restrictions and other provisions of
each Option, including but not limited to whether all or any portion of each
Option shall be incentive stock options ("Incentive Options") qualifying under
Section 422 of the Code or stock options which do not so qualify
("Non-Qualified Options"); the time or times when the Option may be exercised;
the term of such Option; the events of termination of such Option; the
transferability of such Option; and any voting, transfer or other restrictions
on the shares of Common Stock issuable upon exercise of the Option. Both
Incentive Options and Non-qualified Options may be granted to the same person
at the same time, provided each type of Option is clearly designated. Options
may be granted as alternatives to or replacements of Options outstanding under
the Plan or of options or other awards under any other plan or arrangement of
the Company or any subsidiary (including a plan or arrangement of a business
or entity, all or a portion of which is acquired by the Company or a
subsidiary). In making such determinations, the Committee may take into
account the nature of the services rendered by such persons, their present and
potential contribution to the success of the Company or a subsidiary and such
other factors as the Committee in its sole discretion may deem relevant.

         (b) the Committee shall also have authority to interpret the Plan, to
establish, amend and rescind rules and regulations relating to the Plan, to
determine the terms and provisions of the respective agreements evidencing the
grant of Options ("Option Agreements"), and to make all other determinations
that may be necessary or advisable for the administration of the Plan.

         (c) except as otherwise provided in the Plan, where the Committee
shall be authorized to make a determination with respect to any Option, such
determination shall be made at the time of the grant of the Option, except
that the Committee reserves the authority to have such determination made by
the Committee in the future (but only if such reservation is made at the time
the Option is granted and is expressly stated in the Option Agreement relating
to such Option).

         (d) Any interpretation of the Plan by the Committee and any decision
made by it under the Plan shall be final and not subject to review.


                                      2

         4. Eligibility for Receipt of Options.

         (a) Incentive Options. Incentive Options may be granted only to
employees (including officers) of the Company and/or any of its subsidiaries.
A director of the Company or any subsidiary who is not an employee of the
Company or of one of its subsidiaries is not eligible to receive Incentive
Options under the Plan. Further, Incentive Options may not be granted to any
person who, at the time the Incentive Option is granted, owns (or is
considered as owning within the meaning of Section 424(d) of the Code) stock
possessing more than 10% of the total combined voting power of all classes of
stock of the Company or any subsidiary ("10% Owner"), unless at the time the
Incentive Option is granted to the 10% Owner, the option price is at least
110% of the fair market value of the Common Stock subject thereto and such
Incentive Option by its terms is not exercisable subsequent to five years from
the date of grant. In the event an outstanding Incentive Option or a portion
thereof no longer qualifies as an incentive stock option under Section 422 of
the Code, such Option or portion thereof, as applicable, thereafter shall be
deemed a Non-Qualified Option under the Plan.

         (b) Non-Qualified Options. Non-Qualified Options may be granted to
any person eligible to receive Options under the Plan (including any
individual who has been granted Incentive Options) whom the Committee
determines will contribute to the success of the Company or a subsidiary.

         (c) Maximum Number of Options Granted Annually to any Person. The
maximum number of shares that may be subject to Options under this Plan
granted during any calendar year to any employee of the Company or its
subsidiaries is 700,000 shares.

         5. Exercise Price; Date of Grant.

         (a) Exercise Price. The exercise price of each Option shall be
determined by the Committee, in its sole discretion, which determination shall
be conclusive and not subject to review, but in no event shall the exercise
price for Incentive Stock Options be less than 100% of the Fair Market Value
of the Common Stock on the date of grant (or 110% of Fair Market Value with
respect to Incentive Options granted to a 10% Owner) and for Non Qualified
Stock Options, 75% of the Fair Market Value of the Common Stock on the date of
grant.

         (b) Date of Grant. For purposes of the Plan, the date of grant of an
Option shall be the date on which the Committee (or Board) shall duly
authorize the Option.

         6. Term of Option.

         (a) The term of each Option shall be such number of years as the
Committee shall determine, subject to earlier termination as herein provided
or as determined by the Committee, but in no event more than ten years from
the date the Option is granted (or five years in the case of an Incentive
Option granted to a 10% Owner).

         (b) If the employment of the holder of an Incentive Option shall be
terminated for any reason other than such holder's disability (as such term is
defined in Section


                                      3
<PAGE>

22(e)(3) of the Code) or death, the Option shall terminate no later than three
months from the date of termination of employment or at such earlier date as
determined by the Committee and set forth in the Option Agreement.

         (c) If the employment of the holder of an Incentive Option shall be
terminated by reason of such holder's disability (as such term is defined in
Section 22(e)(3) of the Code) or death, the Option shall terminate no later
than twelve months from the date of such termination of employment or at such
earlier date as determined by the Committee and set forth in the Option
Agreement.

         (d) Any Option exercisable after the date of termination of
employment shall be exercisable only to the extent such Option was exercisable
at the date of termination of employment.

         (e) Notwithstanding anything to the contrary contained herein, no
Option may be exercised following the termination or expiration of such
Option.

         7. Exercise of Options.

         (a) Each Option shall be exercisable in accordance with the terms and
conditions and during such periods as may be established by the Committee.
However, the aggregate fair market value (determined as of the time an
Incentive Option is granted) of the shares of Common Stock initially
purchasable upon exercise of Incentive Options by the holder thereof during
any calendar year may not exceed $100,000. In the event that the aggregate
fair market value of stock with respect to which Incentive Options are
exercisable for the first time by you during any calendar year exceeds
$100,000, any Incentive Options with respect to stock in excess of such
$100,000 amount shall be automatically converted and treated as Non-Qualified
Options.

         (b) An Option may not be exercised for fractional shares of the
Company's Common Stock.

         (c) The exercise of an Option shall be contingent upon receipt from
the holder thereof of a written representation that at the time of such
exercise it is the optionee's then present intention to acquire the Option
shares for investment and not with a view to the distribution or resale
thereof (unless a Registration Statement covering the shares purchasable upon
exercise of the Options shall have been declared effective by the Securities
and Exchange Commission) and upon receipt by the Company of cash, or a check
to its order, for the full purchase price of such shares. The Committee may,
in its discretion, include a "cashless exercise" provision in the applicable
Option Agreement, in which event the optionee will be permitted (i) to deliver
previously owned shares of Common Stock with a Fair Market Value as of the
date of exercise equal to the exercise price in payment of the full purchase
price of such shares; provided, however, any such tendering shares, if
purchased upon exercise of a stock option, shall have been held for at least
six (6) months, or (ii) to request that the Company withhold shares of Common
Stock issuable upon exercise of such Option with a Fair Market


                                      4
<PAGE>

Value as of the date of exercise equal to the exercise price of the shares
being purchased under the Option (thereby reducing the number of shares
issuable upon exercise of the Option).

         (d) An Option may not be exercised for fractional shares of the
Common Stock.

         (e) The holder of an Option shall have none of the rights of a
stockholder with respect to the shares purchasable upon exercise of the Option
until a certificate for such shares shall have been issued to the holder upon
due exercise of the Option.

         (f) The proceeds received by the Company upon exercise of an Option
shall be added to the Company's working capital and be available for general
corporate purposes.

         8. Transferability of Options. Except as otherwise provided by the
Committee in an Option Agreement, no Option shall be transferable otherwise
than by will or the laws of descent or distribution. The Committee shall have
the authority to provide in the Option Agreement for transferability of an
Option by the holder of the Option for no consideration to or for the benefit
of the holder's Family Group, subject to such conditions or limitations as the
Committee may establish and the transferee shall remain subject to all of the
terms and conditions applicable to the Option prior to such transfer.

         9. No Rights of Employment. Nothing in the Plan or in any Option
Agreement granted hereunder shall confer upon any holder of an Option any
right to continue in the employ of the Company or any subsidiary or obligate
the Company or any subsidiary to continue the engagement of any holder of an
Option or interfere in any way with the right of the Company or any subsidiary
to terminate the employment or engagement of the holder of an Option at any
time.

         10. Adjustments Upon Changes in Capitalization. If at any time after
the date of grant of an Option, the Company shall by stock dividend, split-up,
combination, reclassification or exchange, or through merger or consolidation
or otherwise, change its shares of Common Stock into a different number or
kind or class of shares or other securities or property, then the number of
shares covered by such Option and the price per share thereof shall be
proportionately adjusted for any such change by the Committee, whose
determination thereon shall be conclusive.

         11. Vesting of Rights Under Options. Neither anything contained in
the Plan nor in any resolution adopted or to be adopted by the Committee or
the stockholders of the Company shall constitute the vesting of any rights
under any Option. The vesting of such rights shall take place only (i) when a
written Option Agreement shall be duly executed and delivered by and on behalf
of the Company and the person to whom the Option shall be granted, and (ii) on
the terms and conditions set forth in such Option Agreement.

         12. Withholding Taxes. The Company shall have the right to require
the exercising holder of an Option to remit to the Company an amount
sufficient to satisfy any


                                      5
<PAGE>

federal, state and local withholding tax requirements resulting from or
attributable to such exercise.

         13. Compliance with Laws. The grant of Options and the issuance of
Common Stock upon exercise thereof shall be subject to and conditioned upon
compliance with all applicable requirements of law, including without
limitation compliance with the Securities Act of 1933, compliance with
applicable state securities laws and compliance with the requirements of any
stock exchange on which the Common Stock may then be listed. The Company shall
have no obligation to register the Common Stock under the Securities Act or
any state securities laws.

         14. Applicable Law. The validity, interpretation and enforcement of
this Plan shall be governed in all respects by the laws of the State of
California (without giving effect to any choice of law or conflict of law
rules or provisions that would cause the application of the laws of any
jurisdiction other than the State of California) and the United States of
America.

         15. Termination and Amendment; Successors. The Plan, which was
adopted by the Board on September __, 1999, subject to stockholder approval,
shall terminate on September __, 2009 and no Option shall be granted under the
Plan after such date. The Committee may at any time terminate or amend this
Plan in any respect (including, but not limited to, any form of Grant,
agreement or instrument to be executed pursuant to this Plan); provided,
however, that shareholder approval shall be required to be obtained by the
Company if required to comply with the provisions of Section 162(m) of the
Code, or the listed company requirements of The Nasdaq National Market or of a
national securities exchange on which the Shares are traded, or other
applicable provisions of state or federal law or self-regulatory agencies;
provided, further, that no amendment of this Plan may adversely affect any
then outstanding Options or any unexercised portions thereof without the
written consent of the Optionee.

                  The obligations of the Company under the Plan shall be
binding upon any successor corporation or organization resulting from the
merger, consolidation or other reorganization of the Company, or any successor
corporation or organization succeeding to all, or substantially all, of the
assets and business of the Company. In the event of any of the foregoing, the
Committee may, at its discretion prior to the consummation of the transaction
and subject to the first paragraph of this section, cancel, offer to purchase,
exchange, adjust or modify any outstanding Options, at such time and in such
manner as the Committee deems appropriate and in accordance with applicable
law.

                  Upon the reorganization, merger or consolidation of the
Company as a result of which the Company is not the surviving corporation, or
upon a sale of substantially all the property of the Company to another
corporation, the Plan shall terminate and any outstanding unexercised Options
shall terminate, unless provision be made in connection with such transaction
for the assumption of such Options, or the substitution of such Options for
new options covering the stock of a successor employer corporation or a parent
or subsidiary thereof with appropriate adjustments as to the number and kind
of shares and purchase prices. The Company shall provide each holder of an
Option fifteen (15) days' prior written notice of any transaction which would
cause the termination of outstanding Options under this paragraph.


                                      6

         16. Definitions. The following terms shall have the meanings set
forth below for purposes of this Plan.

         (a) "Fair Market Value" of a share of Common Stock as of a specified
date shall mean (i) the closing sale price of the Common Stock on the Nasdaq
Small Cap Market (or on such other body on which the Common Stock is then

Market Value is being determined, (ii) if the closing sale price of the Common
Stock is not so quoted, then the mean between the high and low quoted sale
prices of the Common Stock on the last preceding date on which sales were

the most recent bid and asked prices of the Common Stock quoted by a market
maker or other recognized specialist in the Common Stock.

         (b) "Family Group" shall mean the descendants (whether natural or

exercised only upon the terms and conditions set forth below.

         1. Purpose of Option.

                  The purpose of the plan under which this incentive stock

corporations who are expected to contribute to the Company's future growth and
success.

         2. Acceptance of Option Agreement.

                  Your execution of this incentive stock option agreement will
indicate your acceptance of and your willingness to be bound by its terms and
the terms of the Plan, a copy of which has been or is simultaneously herewith
being delivered to you; Your execution of this incentive stock option
agreement imposes no obligation upon you to purchase any of the shares subject

         3. When Option May Be Exercised.

                  The option granted you hereunder shall become exercisable as

schedule].

                  This option may not be exercised for less than [number]
shares at any one time (or the remaining shares then purchasable if less than
[number]) and expires at the end of ten (10) years from the date of grant
whether or not it has been duly exercised (hereinafter, the "Option Expiration
Date"), unless sooner terminated as provided in the Plan.

         4. How Option May Be Exercised.

                  This option is exercisable by a written notice substantially
in the form of Exhibit A signed by you and delivered to the Company at its
executive offices, signifying your election to exercise the option. The notice
must state the number of shares of Common Stock as to which your option is
being exercised, must contain a statement by you (in a form acceptable to the
Company) that such shares are being acquired by you for investment and not
with a view to their distribution or resale (unless a Registration Statement
covering the shares purchasable has been declared effective by the Securities
and Exchange Commission) and must be accompanied by cash or a check to the
order of the Company for the full purchase price of the shares being


                                      8

person or persons other than you, the Company may require, as a condition to
the exercise of this option, the submission to the Company of appropriate
proof of the right of such person or persons to exercise this option.


                  Certificates for shares of the Common Stock so purchased

issuance or sale of such shares or the listing of such shares on said

other person as may be entitled to exercise this option shall have none of the
rights of a stockholder with respect to shares subject to this option.


                  The Company shall have the right to require you, or such
other person as may be permitted to exercise this option, to remit to the
Company an amount sufficient to satisfy federal, state and local withholding
tax requirements prior to the delivery of any certificate or certificates for
shares of Common Stock issuable upon exercise of this option.

         5. Non-Transferability of Option.

                  This option shall not be transferable except by will or the
laws of descent and distribution, and may be exercised during your lifetime
only by you.

two years from the date of grant.

all respects to the terms and conditions of the Plan and in the event of any
question or controversy relating to the terms of the Plan, the decision of the

                     NON-QUALIFIED STOCK OPTION AGREEMENT



To:  _____________

                  We are pleased to notify you that by the determination of
the Compensation Committee (hereinafter the "Committee") a Non-Qualified stock
option to purchase _______ shares of the Common Stock of HealthCore Medical

has this ___ day of ____, ____ been granted to you under the Company's 1999
Stock Option Plan, as amended (herein called the "Plan"). This option may be
exercised only upon the terms and conditions set forth below.

         1. Purpose of Option.

         The purpose of the plan under which this Non-Qualified stock option
has been granted is to secure to the Company and its shareholders the benefits
arising from capital stock ownership by employees, officers and directors of,
and consultants or advisors to, the Company and any subsidiary corporations
who are expected to contribute to the Company's future growth and success.

         2. Acceptance of Option Agreement.

indicate your acceptance of and your willingness to be bound by its terms and
the terms of the Plan, a copy of which has been or is simultaneously herewith

agreement imposes no obligation upon you to purchase any of the shares subject
to this option. Your obligation to purchase shares can arise only upon your
exercise of the option in the manner set forth in paragraph 4 hereof.

         3. When Option May Be Exercised.

         The option granted you hereunder shall become exercisable as follows,
except as otherwise provided in the Plan [determine vesting schedule].

         This option may not be exercised for less than [number] shares at any
one time (or the remaining shares then purchasable if less than [number]) and
expires at the end of ten (10) years from the date of grant whether or not it
has been duly exercised (hereinafter, the "Option Expiration Date"), unless
sooner terminated as provided in the Plan.

         4. How Option May Be Exercised.

         This option is exercisable by a written notice substantially in the
form of Exhibit A signed by you and delivered to the Company at its executive
offices, signifying your election to exercise the option. The notice must

distribution or resale (unless a Registration Statement covering the shares
purchasable has been declared effective by the Securities and Exchange
Commission) and must be accompanied by cash or a check to the order of the
Company for the full purchase price of the shares being purchased, plus such
amount, if any, as is required for withholding taxes. Notwithstanding the
foregoing, this option may also be exercised pursuant to the "cashless
exercise" provision.

         If notice of the exercise of this option is given by a person or
persons other than you, the Company may require, as a condition to the
exercise of this option, the submission to the Company of appropriate proof of
the right of such person or persons to exercise this option.

         Certificates for shares of the Common Stock so purchased will be
issued as soon as practicable. The Company, however, shall not be required to
issue or deliver a certificate for any shares until it has complied with all
requirements of the Securities Act of 1933, the Securities Exchange Act of
1934, any stock exchange on which the Company's Common Stock may then be
listed and all applicable state laws in connection with the issuance or sale
of such shares or the listing of such shares on said exchange. Until the
issuance of the certification for such shares, you or such other person as may
be entitled to exercise this option shall have none of the rights of a
stockholder with respect to shares subject to this option.

         The Company shall have the right to require you, or such other person
as may be permitted to exercise this option, to remit to the Company an amount
sufficient to satisfy federal, state and local withholding tax requirements
prior to the delivery of any certificate or certificates for shares of Common
Stock issuable upon exercise of this option.

         5. Non-Transferability of Option.

         This option shall not be transferable except to members of your
family or to your family trust(s), and by will or the laws of descent and
distribution.

         6. Subject to Terms of the Plan.

         This Non-Qualified stock option agreement shall be subject in all
respects to the terms and conditions of the Plan and in the event of any
question or controversy relating to the terms of the Plan, the decision of the
Committee shall be conclusive.

         7. Tax Status.

provisions of Section 422 of the Internal Revenue Code of 1986, as amended,
and the income tax implications of your receipt of a Non-Qualified stock
option and your exercise of such an option should be discussed with your tax
