Re:      Engagement Agreement

Dear Pete:

     Thank  you  for  asking  Duncan,  Blum &  Associates  to  represent  you in
conjunction  with  BioQuest  International,  Inc.  ("BioQuest")  as  counsel  in
conjunction with BioQuest's  proposed initial and/or direct public offering.  We
appreciate  the  opportunity  to  work  with  you.  Because  our  representation
ultimately  depends on a high degree of trust, it is important for both of us to
be clear about the costs of and limits upon our legal  services from the outset.
For that reason and because  pertinent  Rules of  Professional  Conduct  require
disclosure  of the basis for our fees,  in writing,  this firm requires that our
clients execute an engagement agreement.

     Enclosed is our proposed  Attorney-Client  Fee Agreement in this matter. It
is our standard form. If you have any questions regarding the agreement,  please
do not hesitate to contact me.

     We have attached wire  instructions  for your future  convenience.  We look
forward to the opportunity to represent you in this matter.

                                                Sincerely,
                                                Duncan, Blum & Associates

                          ATTORNEY-CLIENT FEE AGREEMENT

2.   PARTIES  AND  EFFECTIVE  DATE.  THIS  ATTORNEY-CLIENT  FEE  AGREEMENT  (the
     "Agreement") is entered into by and between  BioQuest  International,  Inc.
     ("Client") and Duncan, Blum & Associates  ("Attorneys") and takes effect on
     the date executed by the final party.

3.   SCOPE AND DUTIES.  Client  retains  Attorneys to provide legal  services in
     connection  with your  proposed  initial  and/or  direct  public  offering,
     including a regulatory summary and necessary securities filing(s) to permit
     your  offering to commence in up to twenty  (20)  states.  Attorneys  shall
     provide those legal services  reasonably  required to represent Client, and
     shall keep  Client  informed  of  progress  and shall  promptly  respond to
     Client's  inquiries.  Attorneys'  ability to  effectively  and  efficiently
     represent Client depends upon the full cooperation of Client.

4.   INITIAL RETAINER. Client will deposit with Attorneys the sum of thirty-five
     thousand dollars ($35,000), described in Section 4 below, in this matter to
     be held in a trust account and hereby authorizes Attorneys to withdraw sums
     from that account to pay for the legal services performed. In addition, you
     will  be  forwarding  the  appropriate  filing  fees  associated  with  the
     pertinent  states  (approximately  $1,500 per state and fees payable to the
     SEC in the amount of $1,000 per $5,000,000 offered).

5.   LEGAL FEES. The fee shall be capped.  Specifically,  Client agrees to pay a
     fixed fee of  thirty-five  thousand  dollars  (exclusive  of  out-of-pocket
     disbursements  estimated at  $4,000-$6,000  and the foregoing SEC and state
     filing  fees)  plus the  equity  participation  outlined  in the  following
     sentence.  Once the IPO/DPO is declared  effective  (or in the event Client
     aborts the  offering  for reasons  unrelated  to  Attorneys'  performance),
     Client  will have  BioQuest,  in  addition  to the above  fixed fee,  issue
     warrants and related terms to be negotiated once the capital  structure and
     associated  pricing is ascertained.  (See also "Costs and Expenses" below.)
     The $35,000 fixed fee is due by prompt  payment of the capped fee set forth
     above in Section 3 above.

6.   COSTS AND EXPENSES.  In addition to paying legal fees, Client agrees to pay
     all costs and expenses incurred by Attorneys including, but not limited to,
     the following:  process server,  facsimile  transmission,  express mail and
     messenger fees; court reporter fees;  postage and photocopying;  accountant
     or other expert witness fees; long-distance telephone charges; filing fees;
     any travel meals or lodging;  any computerized legal database service;  and
     other  incidental  expenses  incurred on Client's  behalf.  Attorneys shall
     obtain  Client's   consent  before   retaining  an  outside   investigator,
     consultant or expert  witness or incurring any  extraordinary  expense over
     two hundred and fifty dollars ($250).  Photocopying  and facsimiles will be
     charged to Client at cost/page ($.10 and $1.00 per page, respectively).  If
     Client so directs,  Attorneys will charge, to the extent possible, all such
     expenses directly to Client's already established commercial account

7.   MONTHLY STATEMENT.  Attorneys shall send to Client periodic statements,  at
     intervals of  approximately  30-days,  for any month in which  services are
     rendered and/or costs incurred,  describing all legal services rendered and
     costs and expenses  incurred by Attorneys in  connection  with this matter,
     and  showing  the  balance  of the  retainer,  less cost of legal  services
     performed. Client may request such statements at shorter intervals.

8.   CONCLUSION  OF SERVICES.  When  Attorneys'  services  conclude,  all unpaid
     charges, if any, shall become payable.  After Attorneys' services conclude,
     Attorneys will, upon Client's  request,  deliver  Client's files to Client,
     together with any funds or property of Client's in Attorneys' possession.

9.   DISCHARGE  AND  WITHDRAWAL.  Client may  discharge  Attorneys  at any time.
     Attorneys may withdraw with Client's consent or for good cause.  Good cause
     includes  Client's breach of the Agreement,  Client's  refusal to cooperate
     with Attorneys or any other fact or  circumstance  that renders  Attorneys'
     continuing representation unethical or unlawful.

10.  GOVERNING LAW. The laws of Maryland govern  construction and interpretation
     of the Agreement.

11.  COLLECTION COSTS.  Billings not paid one month from the date of the invoice
     will be subject to a late  payment  charge  equal to one  percent  (1%) per
     month of the outstanding balance.  Should it become necessary for Attorneys
     to enforce the terms and provisions of this Agreement, Client hereby agrees
     to pay all  costs of  collection,  including  the  costs of any  collection
     agency and reasonable attorneys' fees incurred.

12.  DISCLAIMER OF GUARANTEE.  Nothing in this  Agreement will be construed as a
     guarantee or promise about the outcome of this matter. No one can make such
     a guarantee.

                            COLLATERAL LOAN AGREEMENT
                            FOR LOAN NO. 000-ADTM-TD5

This COLLATERAL LOAN AGREEMENT (the "Agreement"), dated this 11th day of August,
2000, is entered into between  Adatom.com,  Inc., a Delaware  corporation with a
principal address at 920 Hillview Court, Suite #190, Milpitas,  California 95035
(the "BORROWER"),  represented by Rich Barton, President, and TRICORP FINANCIAL,
INC., a Delaware corporation (the "LENDER") represented by Charles J. Kerns, Sr.
and Alvin Hayes,  with a principal  address at 222 Lakeview Avenue,  Suite 1330,
West Palm Beach, Florida 33401.

This Agreement  supplants in its entirety any and all earlier Agreements between
the parties.

In consideration of the mutual covenants herein  contained,  and intending to be
legally bound hereby, the parties agree as follows:

1.       LOAN STRUCTURE

         a.       Subject to the terms and conditions hereinafter set forth, the
                  LENDER  agrees to advance two million  United  states  dollars
                  ($2,000,000.00  USD) on four  million  (4,000,000)  shares  of
                  Restricted  14 Class A common  stock of  Adatom,  Inc.,  CUSIP
                  #00650Q-10-5, with symbol ADTM (the "STOCK").
         b.       LENDER will advance funds under the Loan  to  the BORROWER  in
                  two payments:
                           1)       The first  loan  advance  for fifty  percent
                                    (50%) of the Loan amount will be made within
                                    five (5)  business  days of the later of the
                                    delivery  of the  STOCK  and  the  corollary
                                    documents,  or execution of this  Agreement;
                                    and
                           2)       The second and final  loan  advance  for the
                                    other fifty percent (50%) of the Loan amount
                                    will be made within five (5)  business  days
                                    of the date of the first payment.
         c.       The  BORROWER's  obligation  to  repay  the  advance  shall be
                  evidenced  by a  promissory  note(s)  in the form of Exhibit A
                  attached hereto (the "Note"). The Note(s) shall be executed by
                  BORROWER  and   delivered  to  the  LENDER  via  courier  upon
                  notification  by the LENDER that good funds are  available  to
                  advance the Loan
         d.       To secure its  obligations  under the Loan, Rich Barton hereby
                  grants  LENDER a Security  Interest in  the  STOCK.  The STOCK
                  shall be held by the LENDER for the duration of the Loan.
         e.       LENDER will  issue  a  safekeeping  receipt  guaranteeing  the
                  return of the STOCK upon  repayment of the credit line without
                  any liens or encumbrances.
         f.       The credit line may be used to arbitrage  cash, but, if so, an
                  amount will be invested to insure the availability of funds to
                  repay the credit line at all times.
         g.       Return  of the  STOCK  is  subject  to  repayment  of the Loan
                  Principal and accrued  interest and is forfeited if there is a
                  Default as specified in the Note.
         h.       In addition to the share  certificate(s),  the  BORROWER  will
                  deliver a "blank" stock power, one for each certificate,  with
                  medallion signature  guarantee,  a corporate  resolution,  and
                  requisite corollary documents to complete the transaction.
         i.       All parties  understand and agree that the STOCK is subject to
                  a Rule 145  restriction  and  legend as well as a "hold  back"
                  restriction  under  a  subscription  agreement  which  is also
                  legended  on the share  certificate(s).  However,  it has been
                  represented  that  there  are no other  restrictions,  whether
                  legended or not, that apply to the STOCK.

<PAGE>

         j.       This Agreement,  the Promissory Notes, and the other documents
                  specified in this section constitute the "LOAN DOCUMENTS."

2.       LOAN DISBURSEMENTS

         a.       The Loan will be  disbursed  in two  payments as  discussed in
                  LOAN STRUCTURE #1a.
         b.       All loan  proceeds  shall be wired  directly  to the  BORROWER
                  based on wiring  instructions  provided by the BORROWER to the
                  LENDER, without offset of any charges, expenses,  commissions,
                  or other deductions, other than the agreed upon fees.
         c.       Loan proceeds  shall be  immediately  available  funds for the
                  BORROWER.
         d.       The  delivery of the  Promissory  Note(s) to LENDER shall be a
                  Condition Precedent to advancement of the funds by the LENDER.
         e.       In the event the LENDER  does not make the Loan  advance,  the
                  BORROWER's  sole and  exclusive  remedy  shall be to demand an
                  immediate return of any Certificate(s), Stock Power(s) and the
                  Promissory  Note(s).  LENDER  shall  comply  within  five  (5)
                  business days.

3.       PROMISSORY NOTES

         a.       The  STOCK  pledged  under  this  Agreement  will  be  held as
                  collateral  as long as  there  is any  principal  or  interest
                  outstanding under the Promissory Note(s).
         b.       Upon  satisfaction  of all  principal  and interest  under the
                  Note(s),  the LENDER will  deliver any LOAN  DOCUMENTS,  other
                  than  the  LENDER's  copy  of  the  Agreement,  including  any
                  Certificates,  Stock Powers or other documents  related to the
                  STOCK to the BORROWER.
         c.       The LENDER  shall give  written  notice of any Loan default to
                  the BORROWER in accordance with this Agreement and if BORROWER
                  shall fail to cure within ten (10) days after notice, then may
                  sell, assign, hypothecate or otherwise dispose of the STOCK as
                  provided in the Promissory Note(s).
         d.       The LENDER  accepts no  responsibility  for the value obtained
                  through the  disposition  of the STOCK under any lawful means;
                  however,  any value obtained in excess of the default  amount,
                  including reasonable attorney's fees and costs of disposing of
                  such collateral, shall be returned to the BORROWER.
         e.       The STOCK  shall  constitute  the  entire  collateral  used to
                  procure  the  Loan,   and  the  LENDER  shall  be  limited  to
                  liquidation  of the STOCK  upon an Event of Default as defined
                  in the Promissory  Note(s) to the extent  necessary to satisfy
                  the default.
         f.       The  LENDER  shall  have no other  recourse  to other  assets,
                  guarantees,  or assignments of interest of the BORROWER, i.e.,
                  this Loan is  "non-recourse" as to any assets of the BORROWER,
                  other entity, or individual beyond the STOCK.

4.       LOAN CLOSING

         The  Closing  shall  take  place  on the  later of the  delivery  of an
         executed  Agreement  or the receipt of the STOCK and all other forms in
         the account designated by the LENDER.

5.       USE OF STOCK
         a.       The STOCK shall be used as  collateral  to establish a line of
                  credit through the credit  facility  provider.  The STOCK will
                  not be  otherwise  encumbered  in any  other  manner  while on
                  deposit as collateral for this Loan.
         b.       While the STOCK is on deposit,  Rich Barton  shall  retain all
                  voting and dividend rights  incident to its ownership,  except
                  for cash or stock dividends in excess of the Loan Amount.

                               Page 2 of 5 Pages

<PAGE>

         c.       The Stock shall remain on deposit in the  LENDER's  account at
                  all times,  unless returned directly to the BORROWER under the
                  Agreement,  or to the  LENDER  due to an Event of  Default  as
                  defined in the Note.
         d.       The credit line may be used to arbitrage cash,  i.e.,  lease a
                  multiple of the credit  line;  but,  in all cases,  sufficient
                  cash  shall  be  invested  in a risk  free  manner  to  enable
                  repayment of the credit line to allow  release of the STOCK at
                  any time.
         e.       The LENDER  warrants and represents that the STOCK will not be
                  used in any manner other than as collateral; and, that it will
                  not be subject to any other liens or encumbrances,  other than
                  its use as collateral  to establish  the initial  credit line;
                  and, the LENDER accepts full and complete  responsibility  for
                  return  of the  STOCK  upon  satisfaction  of the  Loan by the
                  BORROWER.

6.       BORROWER'S REPRESENTATIONS AND WARRANTIES

         In order to induce the LENDER to advance funds  against the  Promissory
         Note(s),   the  BORROWER  makes  the  following   representations   and
         warranties to the LENDER, which representations and warranties shall be
         unaffected by any investigation  heretofore or hereafter made by LENDER
         and shall survive the closing of the transactions contemplated hereby:

         a.       BORROWER has all  requisite  power and authority to enter into
                  this  Agreement  and  the  other  LOAN  DOCUMENTS,  including,
                  without limitation, the Promissory Notes, and to carry out the
                  transactions contemplated hereby.
         b.       BORROWER warrants and represents that it is not now insolvent,
                  bankrupt, or contemplating  bankruptcy;  or, that there are no
                  bankruptcy or undisclosed  material claims filed or threatened
                  against BORROWER,  whether judged with or without merit by the
                  BORROWER,  or  aware  of  other  impediments  to the  sale  or
                  transfer of the STOCK.
         c.       The execution and delivery of this  Agreement,  the Promissory
                  Note(s) and the other LOAN  DOCUMENTS  and  instruments  to be
                  executed and  delivered by the BORROWER are not subject to any
                  authorization  not  herein  contemplated,  subject  to recall,
                  restriction on voting, use, or other limitations.
         d.       The Agreement  constitutes,  and when executed and  delivered,
                  the  Promissory   Note(s)  and  other  LOAN  DOCUMENTS,   will
                  constitute   valid   binding   agreements   of  the  BORROWER,
                  enforceable in accordance with their respective terms,  except
                  such   as   may  be   limited   by   bankruptcy,   insolvency,
                  reorganization  or  other  laws  affecting  creditors'  rights
                  generally.
         e.       Neither the  execution  and  delivery of this  Agreement,  the
                  Promissory Note(s) or the other LOAN DOCUMENTS and instruments
                  to be executed and delivered by BORROWER pursuant hereto,  nor
                  the consummation by BORROWER of the transactions  contemplated
                  hereby,  will require any  authorization,  consent,  approval,
                  exemption or other  action by, or notice to, any  governmental
                  entity except as specifically provided herein.
         f.       BORROWER has no material  tax  deficiencies,  federal,  state,
                  foreign,  county, local and other, which would or could affect
                  the  solvency,  financial  status of, or otherwise  compromise
                  BORROWER in its ability to transfer the STOCK.
         g.       To the best of its  knowledge,  the  information  supplied  by
                  BORROWER to the LENDER (verbally and in writing)  contained no
                  untrue  statement  of  material  fact or omits or shall omit a
                  material fact,  which would make such  statements  misleading.
                  All statements and information  contained in any  certificate,
                  instrument,  schedule or document  delivered by BORROWER shall
                  be deemed representations and warranties made by BORROWER.

                                 PROMISSORY NOTE

For value received,  Adatom.Com, Inc., a Delaware corporation with an address at

promises to pay TRICORP FINANCIAL, INC. (together with all subsequent holders in
due course) at principal  address at 222 Lakeview Avenue,  Suite 1330, West Palm
Beach,  Florida 33401 (the  "HOLDER"),  the principal sum of two million  United
States  dollars  ($2,000,000.00  USD) with  interest from the date hereof at the
rate of nine point five zero percent (9.50% or .0950) simple  interest per annum
on the terms hereinafter set forth.

This Promissory Note (the "NOTE") is issued under the terms of a Collateral Loan
Agreement  (the  "AGREEMENT")  dated as of August  11,  2000  between  MAKER and
HOLDER,  or as  amended  from time to time by written  agreement  signed by both
these parties, the terms of which are incorporated herein by reference.

1.       PAYMENT TERMS

         PRINCIPAL
         a.       The loan period is for one (1) year.
         b.       The loan  period  can be  extended  with the  approval  of the
                  HOLDER

         INTEREST
         a.       Interest is due each month in arrears.
         b.       Interest is calculated by dividing the total  interest for one

         All amounts are stated and payable in United States Dollars.

2.       NO DEDUCTION OR SET-OFF

         The  principal  and  interest  shall  be  payable  without  set-off  or
         deduction,  unless  specifically added by addendum to this NOTE, at the
         address of the HOLDER set forth in the heading hereof, or at such other
         place as HOLDER may designate in writing.

3.       PREPAYMENT

         a.       The MAKER may prepay any and all principal at any time with no
                  fees or penalties.
         b.       If loan is  prepaid,  all  interest  stops  as of the  date of
                  prepayment.

4.       EVENTS OF DEFAULT

         The  occurrence  of any  one or  more  of the  following  events  shall
         constitute an "Event of Default" hereunder:

         a.       MAKER  shall  have  made  an  assignment  for the  benefit  of
                  creditors  or  composition  with  creditors;  or is  unable or
                  admits  in  writing  its  inability  to pay its  debts as they
                  mature;  or  any  proceeding   relating  to  MAKER  under  any
                  bankruptcy,     bankruptcy    reorganization,

<PAGE>

                  arrangement,  readjustment or debt, receivership,  dissolution
                  liquidation law or statute of any jurisdiction, whether now or
                  hereafter in effect is commenced by or against MAKER;

         b.       Any  representation or warranty made by MAKER in the AGREEMENT
                  shall be false or misleading in material respect; or

         c.       MAKER  shall  breach  or fail to take  any  actions  required,
                  obligated,  or necessary to maintain or fulfill the AGREEMENT;
                  or

         d.       MAKER  shall  fail  to  make  a  timely  interest  payment  or
                  principal  repayment.  "Timely"  shall  mean  within  ten (10)
                  calendar days of when it was due.

5.       ACCELERATION AND REMEDIES

         Should any Event of Default  occur  hereunder  and should MAKER fail to
         cure such default within ten (10) days after notice from HOLDER of such
         default,  then  HOLDER,  at its option and  without  further  notice to
         MAKER, unless expressly required elsewhere, may declare immediately due
         and payable the entire  unpaid  balance of principal and all other sums
         due by MAKER  hereunder  with interest  accrued  thereon at the Default
         Rate as set forth  herein;  and,  payment  thereof  may be  enforced by
         liquidating  the  collateral.  "Liquidation"  shall mean the HOLDER may
         dispose of the Stock by any means to satisfy  the  MAKER's  obligation.
         "Dispose  of  the  Stock  by any  means"  includes:  sale,  assignment,
         hypothecation, transfer, or any other method. If HOLDER employs counsel
         to enforce this NOTE to ensure title and liquidation of the collateral,
         such  cost  shall  be  taken  out  of any  proceeds  obtained  in  such
         liquidation.   HOLDER,  after  deducting  said  interest,   late  fees,
         principal repayment amount, legal charges,  other costs associated with
         the  liquidation,  or other costs shall refund any excess monies to the
         MAKER. "Monies" shall be interpreted strictly as cash receipts realized
         by the HOLDER. The definition shall not include non-monetary  benefits,
         credit  lines,  or other  benefits  which the  HOLDER  may  enjoy  from
         deployment of such collateral.

         Any collateral  held under the  Collateral  Loan Agreement may be sold,
         assigned,  hypothecated,  or otherwise  disposed of to recover  amounts
         enumerated above.

         The  HOLDER  accepts  no  liability  as to price,  purchaser,  or other
         considerations  in the  disposition  of such  collateral  and the MAKER
         waives any right  through  arbitration  or legal remedy to seek to make
         HOLDER accountable for such.

6.       NON-RECOURSE

         The HOLDER  acknowledges  the sufficiency of the collateral,  i.e., the
         Stock, as adequate and sufficient for the principal  amount advanced to
         the MAKER and the HOLDER is precluded  and estopped from making any and
         all claims against the MAKER for other assets,  guarantees,  or actions
         against  any  individual,  corporation  or entity for  recovery  of any
         amounts  owed  to the  HOLDER,  except  in the  fraudulent  inducement,
         incomplete conveyance of the Stock such that the HOLDER, after an Event
         of  Default,   is  unable  to  liquidate  such  Stock;   or,   material
         misrepresentations and invalid warranties of the MAKER which caused the
         HOLDER to enter into the transaction.

7.       CONSENT TO WAIVERS

         MAKER and all endorsers,  sureties,  and guarantors  consent to any and
         all extensions of time, renewals,  waivers or modifications that may be
         granted by HOLDER with  respect to the payment or other  provisions  of
         this NOTE, and to release of the  collateral or any part thereof,  with
         or without substitution.

8.       PARTIAL INVALIDITY

         If any provision of this NOTE is held to be invalid or unenforceable by
         a court of competent  jurisdiction,  the other  provisions of this NOTE
         shall remain in full force and effect and shall be liberally  construed
         in favor of HOLDER in order to effect the provision of this NOTE.

         In addition,  in no event shall the rate of interest exceed the maximum
         rate of interest  permitted to be charged by applicable  law (including
         the  choice  of law  rules)  and any  interest  paid in  excess  of the
         permitted rate shall be refunded to MAKER. Such refund shall be made by
         application  of the excessive  amount of interest paid against any sums
         outstanding and shall be applied in such order as HOLDER may determine.
         If the excessive amount of interest paid exceeds the sums  outstanding,
         the portion  exceeding the said sums  outstanding  shall be refunded in
         cash by HOLDER. MAKER agrees,  however,  that in determining whether or
         not any  interest  payable  under this NOTE  exceeds the  highest  rate
         permitted  by  law,  any  non-principal   payment,   including  without
         limitation  prepayment  fees and late  charges,  shall be deemed to the
         extent  permitted  by law to be an  expense,  fee,  premium  or penalty
         rather than interest.

9.       WAIVER BY HOLDER

         HOLDER shall not be deemed,  by any act of omission or  commission,  to
         have waived any of its rights or remedies  hereunder unless such waiver
         is in  writing  and  signed  by  HOLDER,  and then  only to the  extent
         specifically set forth in the writing.  A waiver on one event shall not
         be  construed  as  continuing  or as a bar to or waiver of any right or
         remedy to a subsequent event.

10.      GOVERNING LAW

         This  instrument  shall be governed by and  construed  according to the
         laws of the State of Delaware.

11.      PARTIES

         Whenever used, the singular number shall include the plural, the plural
         the singular, the use of any gender shall be applicable to all genders,
         and the word  "HOLDER"  and  "MAKER"  shall be  deemed to  include  the
         respective successors and assigns of HOLDER and MAKER.

IN  WITNESS  WHEREOF,  MAKER has hereby  executed  this NOTE on the day and year
first above written.

                           ADDENDUM TO PROMISSORY NOTE

1.       PREPAYMENT OF INTEREST

         a.       The MAKER may, by its own choice,  prepay any and all interest
                  as calculated in the Promissory  Note. If MAKER chooses at any
                  date to prepay any portion of the interest which is calculated
                  to accrue on the principal over the one year life of the loan,
                  HOLDER  agrees  the  amount  of  interest  paid will no longer
                  become due at the  requisite  date as  calculated in the NOTE.
                  HOLDER agrees the interest  payment  obligations of MAKER will
                  be fulfilled as to the amount of interest paid.

         b.       HOLDER  agrees  MAKER will not be in default of the NOTE after
                  MAKER  chooses  to  prepay  any  amount  of  interest  on  the
                  principal.

         c.       HOLDER  agrees  MAKER may prepay any and all  interest  at any
                  time with no fees or penalties.

         d.       Entire  principal  is due at the  maturity  date  if  interest
                  payments  have  been  prepaid  or made on a  timely  basis  in
                  accordance with Exhibit A, Section 1 of the Promissory Note.
