                            STOCK OPTION AGREEMENT
                                     UNDER
         THE BIOLYNX.COM, INC. 1999 STOCK INCENTIVE COMPENSATION PLAN

     THIS STOCK OPTION AGREEMENT is entered into effective on the 15th day of
January 2000, by and between BIOLYNX.COM, INC., a Texas corporation (the
"Company"), and REAGAN E. HICKS, a resident of Bexar County, Texas (the
"Employee").

     WHEREAS, on May 7, 1999, the Company adopted its 1999 Stock Incentive
Compensation Plan (the "Plan"); and

     WHEREAS, the Plan provides for the issuance of options to purchase shares
of the common stock of the Company, par value $0.001 per share (the "Shares");

     WHEREAS, the Company desires to grant to the Employee an options to
purchase 100,000 of the Shares in conformity with the Plan;

     NOW, THEREFORE, for and in consideration of the mutual covenants contained
herein and for other good and valuable consideration, the receipt, adequacy and
sufficiency of which are hereby acknowledged, the parties hereby agree as
follows:

1. Grant of Options. The Company hereby grants to the Employee options (the
"Options") to purchase all or any portion of 100,000 Shares at a purchase price
equal to $4.00 per Share (the "Exercise Price") in accordance with the terms of
this Agreement, and pursuant to the Plan.

2. Vesting of Options. The Employee's right to exercise the Options shall vest
at a rate of 25 percent (25,000 shares) for each year of employment the Employee
completes with the Company. For purposes of this Stock Purchase Agreement, the
Employee will be deemed to have completed a year of employment if the Employee
remains employed with the Company as of each January 15th of the years 2001,
2002, 2003 and 2004. Therefore, if the Employee remains employed with the
Company on such date, the Employee's right to exercise the Options shall be
fully vested as of January 15, 2004. In the event the Employee terminates his
employment, or the Company terminates the Employee's employment for "cause"
(defined as the Employee's negligence or failure to perform services in
accordance with reasonable industry standards) then (i) any Options that are
exercisable as of the date of such termination shall be deemed earned by the
Employee, surviving termination and exercisable on or before December 31, 2005,
and (ii) any Options that are not yet exercisable as of the date of such
termination of employment will terminate automatically without notice and be of
no further force or effect. Notwithstanding anything in this Agreement to the
contrary, the Options will terminate automatically without notice and be of no
further force or effect to the extent the Options are not yet exercised on
December 31, 2005.

3. Manner of Exercise of Options. The Options may be exercised on one or more
occasions, but can only be exercised for whole Shares. The Options shall be
exercised by the Employee by delivering to the Company (i) written notification
that any or all of the Options are exercisable, including evidence reasonably
satisfactory to the Company to that effect, (ii) the cash required to pay in
full an amount equal to the total Exercise Price for the number of Shares so
exercised. Then, the Company shall deliver to the Employee certificate(s) for
the Shares (collectively, the "Option Shares"). The Employee shall execute such
documents and instruments as requested by the Company to evidence the issuance
of the Option Shares.

4.  Transferability of Options. Except as herein set forth, the Options shall
not be transferable by the Employee and shall be exercisable only by the
Employee.

5.   Requirements of Law.

     (a) Compliance with Laws. The Company shall not be required to sell or
issue any Option Shares under this Agreement if the issuance of the Option
Shares will constitute a violation by the Employee or the Company of any
provisions of any law or regulation of any governmental authority or the Bylaws
of the Company. The Company shall not be obligated to take any affirmative
action other than that which is specifically set forth in this Paragraph 5 in
order to cause the exercise of the Options or the issuance of Option Shares
pursuant hereto to comply with any law or regulation of any governmental
authority.

      (b) Federal and State Securities Laws. Upon exercise of the Options,
unless a registration statement under the Securities Act of 1933, as amended
(the "Securities Act"), is in effect with respect to the Option Shares covered
hereby, the Company shall not be required to issue such Option Shares unless the
Company has received evidence reasonably satisfactory to it that such issuance
is exempt from registration under the Securities Act and all applicable state
securities laws. Subject to the Registration Rights Agreement described below,
the Company may, but shall in no event be obligated to register any securities
covered hereby pursuant to the Securities Act or any applicable state securities
laws. Unless registered or exempt from restriction, the certificate(s) issued
representing the Option Shares shall bear a legend in substantially the
following form:

   "The Shares represented by this certificate have not been registered under
   the Securities Act of 1933, as amended, or under the securities laws of any
   state and may not be sold or transferred except upon such registration or
   upon receipt by the Company of an opinion of counsel reasonably satisfactory
   to the Company that registration is not required for such sale or transfer."

       (c) Investment Intent. The Employee represents and warrants that the
Options and Option Shares are being acquired solely for the account of the
Employee for investment purposes only and not with a view to or for the resale,
distribution, subdivision, or fractionalization thereof; the Employee has no
contract, understanding, undertaking, agreement, or arrangement with any person
to sell, transfer or pledge to any person the Options or Option Shares or any
part thereof; the Employee has no present plans to enter into any such contract,
undertaking, agreement or arrangement; the Employee understands the legal
consequences of the foregoing representations and warranties to mean that the
Employee must bear the economic risk of the investment in the Option Shares for
an indefinite period of time; the Employee has such knowledge and experience in
financial and business matters that the Employee is capable of evaluating the
merits and risks of acquiring the Option Shares; and the Employee acknowledges
that the acquisition of the Option Shares involves a high degree of risk that
may result in the loss of the total amount of the Employee's investment in the
Options and Option Shares.

       (d) Due Diligence. The Employee acknowledges that he has for a reasonable
amount of time had an opportunity to ask questions and receive answers
concerning the terms and conditions of the issuance of the Options and Option
Shares and the actual and proposed business and affairs of the Company, and is
satisfied with the results thereof, and been given access, if requested, to all
documents with respect to the Company or this transaction, as well as to such
other information that the Employee has requested to evaluate an investment in
the Options and Option Shares. The Employee has made his own determination of
the value of the Options and has not received or relied upon any statements,
representations, or warranties of the Company or its agents or representatives.

6. No Rights as Shareholder. The Employee shall have no rights as a shareholder
of the Company with respect to the Option Shares until the date of issuance of a
certificate for the Option Shares; no adjustment for distributions, or
otherwise, shall be made if the record date therefor is prior to the date of
issuance of such certificate.

7.  Changes in the Company's Structure.

       (a) Changes in Structure. The existence of the Options shall not affect
in any way the right or power of the Company, directors, or its shareholders to
make or authorize any or all adjustments, recapitalization, reorganizations or
other changes in the Company's capital structure or its business, or any merger
or consolidation of the Company, or any issue of bonds, debentures, or any other
security or the dissolution or liquidation of the Company, or any sale or
transfer of all or any part of its assets or business or any other corporate act
or proceeding, whether of a similar character or otherwise.

                                       2
<PAGE>

       (b) Changes in Number of Shares. If, while the Options are outstanding,
the Company shall effect a subdivision or consolidation of Shares or other
capital readjustment, the payment of a Share dividend, or other increase or
reduction of the number of Shares outstanding, without receiving compensation
therefor in money, services, or property, then (i) in the event of such an
increase in the number of Shares outstanding, the number of Option Shares then
subject to the Options shall be proportionately increased, and the Exercise
Price shall be proportionately reduced and (ii) in the event of such a reduction
in the number of Shares outstanding, the number of Option Shares then subject to
the Options shall be proportionately reduced, and the Exercise Prices shall be
proportionately increased.

       (c) Changes in Corporate Structure. After a merger of one or more
corporations into the Company or after a consolidation of the Company and one or
more corporations in which the Company shall be the surviving corporation, the
Employee shall, at no additional cost, be entitled upon exercise of the Options
to receive (subject to any required action by shareholders) in lieu of the
number of Option Shares as to which the Options shall then be so exercisable,
the number and class of shares or other securities to which the Employee would
have been entitled pursuant to the terms of the agreement of merger or
consolidation if, immediately prior to such merger or consolidation, the
Employee had been the holder of record of a number of Shares equal to the number
of Option Shares as to which the Options shall be so exercised. In the event the
Company agrees to be merged with or consolidated into one or more corporations
or other entities in which the Company shall not be the surviving entity then,
the Company shall, prior to such merger or consolidation, obtain the full and
unconditional agreement of such surviving entity to assume all of the
obligations of the Company under this Agreement.

       (d) Issuance of Shares. Except as hereinbefore expressly provided, the
issuance by the Company of shares of any class, or securities convertible into
shares of any class, for cash or property, or for labor or services, either upon
direct sale or upon the exercise of rights or warrants to subscribe therefor, or
upon conversion of shares or obligations of the Company convertible into such
shares or other securities, shall not affect, and no adjustment by reason
thereof shall be made with respect to, the number or price of the Shares then
subject to the Options.

8.    Expenses. Each party shall pay its own expenses, including legal expenses
and attorneys' fees, which have been or may be incurred in connection with the
preparation, administration, amendment, or modification of this Agreement and
the other documents and instruments executed in connection herewith.

13.   Governing law; Jurisdiction. This Agreement shall be governed by and

waives, to the fullest extent permitted by law, any objection which it may now

such mediation, arbitration, suit, action or proceeding brought in such county

14.  Arbitration. Any controversy or claim arising out of or relating to this

to be asserted. No delay or omission on the part of any party in exercising any
right, power or privilege hereunder shall operate as a waiver thereof, nor shall
any waiver on the part of any party of any right, power or privilege hereunder
operate as a waiver of any other right, power or privilege hereunder nor shall
any single or partial exercise of any right, power or privilege hereunder
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege hereunder. All remedies, either under this Agreement
or by law or otherwise afforded to any party, shall be cumulative and not

invalid, unenforceable or void, such decision will not have the effect of
invalidating or voiding the remainder of this Agreement or affect the
application of such provision to other persons or circumstances, and the parties
agree that the part or parts of this Agreement so held to be invalid,
unenforceable or void will be deemed to have been stricken herefrom and the
remainder of this Agreement will have the same force and effect as if such part

                         REGISTRATION RIGHTS AGREEMENT

     THIS AGREEMENT is entered into as of November 19, 1999, by and between
BIOLYNX.COM, INC., a Texas corporation (the "Company"), and SABINAL TRUST (the
"Holder").

     WHEREAS, on even date herewith the Company executed and delivered to the
Holder that certain Letter Agreement (the "Letter Agreement") whereby the
Company has agreed to issue to the Holder up to 200,000 shares of the Company's
common stock, par value $0.001 per share (the "Common Stock"), upon the
performance by the Holder as described in the Letter Agreement;

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained herein, and other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties hereto agree as
follows:

1.  Registration Rights Available. Pursuant to the terms and conditions
contained herein, and in the Letter Agreement, the Company agrees to provide the
Holder or any permitted assignee of the Holder (collectively, the "Holder") with
the right to "piggyback" (the "Registration Rights") on a firm commitment
underwritten offering with respect to the Common Stock and any other securities
issued or issuable at any time or from time to time in respect of the Common
Stock as a result of a merger, consolidation, reorganization, stock split, stock
dividend, recapitalization or other similar event involving the Company
(collectively, the "Registrable Securities").

2.   Registration Rights. With respect to the Registration Rights, the parties
agree as follows:

     (a) Subject to Paragraph 2(b), the Company will (i) promptly give to the
Holder written notice of any registration relating to an Underwritten Public
Offering, and (ii) include in such registration (and related qualification under
blue sky laws or other compliance) such of the Holder's Registrable Securities
as are specified in the Holder's written request or requests, mailed in
accordance with the terms of this Agreement within 30 days after the date of
such written notice from the Company.

     (b) The right of the Holder to registration pursuant to the Registration
Rights shall be conditioned upon the Holder's participation in such
underwriting, and the inclusion of the Registrable Securities in the
underwriting shall be limited to the extent provided herein. The Holder shall
(together with the Company) enter into an underwriting agreement in customary
form with the managing underwriter selected for the Underwritten Public Offering
by the Company. Notwithstanding any other provision of this Agreement, if the
managing underwriter determines that marketing factors require a limitation of
the number of the Registrable Securities to be underwritten, the managing
underwriter may limit some or all of the Registrable Securities that may be
included in the registration and the Underwritten Public Offering as follows:
the number of the Registrable Securities that may be included in the
registration and the Underwritten Public Offering by the Holder shall be
determined by multiplying the number of the shares of the Registrable Securities
of all selling shareholders of the Company which the managing underwriter is
willing to include in such registration and the Underwritten Public Offering
times a fraction, the numerator of which is the number of the Registrable
Securities requested to be included in such registration and the Underwritten
Public Offering by the Holder, and the denominator of which is the total number
of the Registrable Securities which all selling shareholders of the Company have
requested to be included in such registration and the Underwritten Public
Offering. To facilitate the allocation of shares in accordance with the above
provisions, the Company may round the number of shares allocable to any such
person to the nearest 100 shares. If the Holder disapproves of the terms of any
such underwriting, it may elect to withdraw therefrom by written notice to the
Company and the managing underwriter, delivered not less than seven days before
the effective date of the Underwritten Public Offering. Any of the Registrable
Securities excluded or withdrawn from the Underwritten Public Offering shall be
withdrawn from such registration, and shall not be transferred in a public
distribution prior to 60 days after the effective date of the Registration
Statement relating thereto, or such other shorter period of time as the
underwriters may require.

3.   Registration Procedure. With respect to the Registration Rights, the
following provisions shall apply:

                                       1
<PAGE>

     (c) The Holder shall be obligated to furnish to the Company and the
underwriters such information regarding the Registrable Securities and the
proposed manner of distribution of the Registrable Securities as the Company and
the underwriters may request in writing and as shall be required in connection
with any registration, qualification or compliance referred to herein and shall
otherwise cooperate with the Company and the underwriters in connection with
such registration, qualification or compliance.

     (d) With a view to making available the benefits of certain rules and
regulations of the Securities and Exchange Commission (the "SEC") which may at
any time permit the sale of any Restricted Securities as defined in Rule 144
("Rule 144") promulgated under the Securities Act of 1933, as amended (the
"Securities Act") to the public without registration, the Company agrees to use
its best lawful efforts to:

               (i) Make and keep public information available, as those ten-ns
are understood and defined in Rule 144 at all times during which the Company is
subject to the reporting requirements of the Securities Exchange Act of 1934, as
amended (the "Exchange Act");

              (ii) File with the SEC in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act
(at all times during which the Company is subject to such reporting
requirements); and

             (iii) So long as the Holder owns any Restricted Securities, to
furnish to the Holder upon request a written statement from the Company as to
its compliance with the reporting requirements of Rule 144 and with regard to
the Securities Act and the Exchange Act (at all times during which the Company
is subject to such reporting requirements), a copy of the most recent annual or
quarterly report of the Company, and such other reports and documents of the
Company and other information in the possession of or reasonably obtainable by
the Company as the Holder may reasonably request in availing itself of any rule
or regulation of the SEC allowing the Holder to sell any Restricted Securities
without registration.

     (e) The Company agrees that it will furnish to the Holder such number of
prospectuses meeting the requirements of Section 10(a)(3) of the Securities Act,
offering circulars or other documents incident to any registration,
qualification or compliance referred to herein as provided or, if not otherwise
provided, as the Holder from time to time may reasonably request.

     (f) All expenses (except for any underwriting and selling discounts and
commissions and legal fees for the Holder's attorneys) of any registrations
permitted pursuant to this Agreement and of all other offerings by the Company
(including, but not limited to, the expenses of any qualifications under the
blue sky or other state securities laws and compliance with governmental
requirements of preparing and filing any post-effective amendments required for
the lawful distribution of the Registrable Securities to the public in
connection with such registration, of supplying prospectuses, offering circulars
or other documents) will be paid by the Company.

     (g) In connection with the preparation and filing of any Registration
Statement under the Securities Act pursuant to this Agreement, the Company will
give the Holder and the Holder's attorneys and accountants, the opportunity to
participate in the preparation of any Registration Statement, each prospectus
included therein or filed with the SEC, and each amendment thereof or supplement
thereto, and will give each of them such access to its books and records and
opportunities to discuss the business of the Company with its officers and the
independent public accountants who have certified its financial statements as
shall be necessary to conduct a reasonable investigation within the meaning of
the Securities Act.

     (h) The Company shall notify each Holder of Registrable Securities covered
by a Registration Statement, during the time when a prospectus relating thereto
is required to be delivered under the Securities Act, of the happening of any
event as a result of which the prospectus included in the Registration
Statement, as then in effect, includes an untrue statement of a material fact or
omits to state a material fact required to be stated therein or necessary to
make the statements therein not misleading in the light of the circumstances
then existing.

4.   Blackout Period. At any time after the effective date of the Registration
Statement, if the Company gives to the Holder a notice pursuant to Paragraph
3(f) hereof and stating that the Company requires the suspension by the

                                       2
<PAGE>

Holder of the distribution of any of the Registrable Securities, then the Holder
shall cease distributing the Registrable Securities for such period of time (the
"Blackout Period"), not to exceed 120 days from the time notice is sent until
the Company informs the Holder that the Blackout Period has been terminated.
Upon notice by the Company to the Holder of such determination, the Holder will
(a) keep the fact of any such notice strictly confidential, (b) promptly halt
any offer, sale, trading or transfer of any of the Registrable Securities for
the duration of the Blackout Period, and (c) promptly halt any use, publication,
dissemination or distribution of each prospectus included within the
Registration Statement, and any amendment or supplement thereto by it and any of
its affiliates for the duration of the Blackout Period.

5. Lock-Up. In connection with any Underwritten Public Offering, the Holder
agrees, if requested, to execute a lock-up letter addressed to the managing
underwriter in customary form agreeing not to sell or otherwise dispose of the
Registrable Securities owned by the Holder (other than any that may be included
in the offering) for a period not exceeding 180 days.

6. Delay of Registration. No Holder shall have any right to obtain or seek an
injunction restraining or otherwise delaying any registration of the Registrable
Securities as the result of any controversy that might arise with respect to the
interpretation or implementation of this Agreement.

7. Indemnification by the Company. In the event of any registration of the
Registrable Securities of the Company under the Securities Act, pursuant to the
terms of this Agreement, the Company agrees to indemnity and hold harmless the
Holder and each other person who participates as an underwriter in the offering
or sale of the Registrable Securities against any and all claims, demands,
losses, costs, expenses, obligations, liabilities, joint or several, damages,
recoveries and deficiencies, including interest, penalties and attorneys' fees
(collectively the "Claims"), to which the Holder or any such underwriter may
become subject under the Securities Act or otherwise, insofar as the Claims or
actions or proceedings, whether commenced or threatened, in respect thereto
arise out of or are based on any untrue statement or alleged untrue statement of
any material fact contained in any Registration Statement under which the
Holder's Registrable Securities were registered under the Securities Act, any
preliminary prospectus, final prospectus or summary prospectus contained
therein, or any amendment or supplement thereto, or any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and the Company will
reimburse the Holder and each such underwriter for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
Claim or action or proceeding in respect thereto; provided that the Company
shall not be liable in any such case to the extent that any Claim or action or
proceeding in respect thereof or expense arises out of or is based on an untrue
statement or alleged untrue statement or omission or alleged omission made in
the Registration Statement, any such preliminary prospectus, final prospectus,
summary prospectus, amendment or supplement in reliance on and in conformity
with written information furnished to the Company through an instrument duly
executed by the Holder specifically stating that it is for use in the
preparation thereof. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of the Holder or any such
underwriter and survive the transfer of the Registrable Securities by the
Holder.

8. Indemnification by the Holder. The Company may require, as a condition to
including the Registrable Securities in any Registration Statement filed
pursuant to this Agreement, that the Company shall have received an undertaking
satisfactory to it from the Holder, to indemnify and hold harmless (in the same
manner and to the same extent as set forth in Paragraph 7 hereof) the Company,
each director and officer of the Company and each other person, if any, who
controls the Company within the meaning of the Securities Act, with respect to
any statement or alleged statement or alleged statement in or omission or
alleged omission from the Registration Statement, any preliminary prospectus
contained therein, or any amendment or supplement thereto, if such statement or
alleged statement or omission or alleged omission was made in reliance on and in
conformity with written information furnished to the Company through an
instrument duly executed by the Holder specifically stating that it is for use
in the preparation of the Registration Statement, preliminary prospectus, final
prospectus, summary prospectus, amendment or supplement. Notwithstanding the
foregoing, the maximum liability hereunder which the Holder shall be required to
suffer shall be limited to the net proceeds to the Holder from the Registrable
Securities sold by the Holder in any such offering. Such indemnity shall remain

of the Company or any such director, officer or controlling person and shall
survive the transfer of the Registrable Securities by the Holder.

9. Notice of Claims. Promptly after receipt by an indemnified party of notice of
the commencement of any action or proceeding involving a Claim, such indemnified
party will, if a claim in respect thereof is to be made against an indemnifying
party, give written notice to the latter of the commencement of such action,
provided that the failure of any indemnified party to give notice as provided
herein shall not relieve the indemnifying party of its obligations under this
Agreement except to the extent that the indemnifying party is actually
prejudiced by such failure to give notice. In case any such action is brought
against an indemnifying party, unless in such indemnified party's reasonable
judgment a conflict of interest between such indemnified and indemnifying
parties may exist in respect of a Claim the indemnifying party shall be entitled
to participate in and to assume the defense thereof, jointly with any other
indemnifying party similarly notified to the extent that it may wish, with
counsel reasonably satisfactory to such indemnified party, and after notice from
the indemnifying party to such indemnified party of its election so to assume
the defense thereof, the indemnifying party shall not be liable to such
indemnified party for any legal or other expenses subsequently incurred by the
latter in connection with the defense thereof other than reasonable costs of
investigation. No indemnifying party shall, without the consent of the
indemnified party, consent to entry of any judgment or enter into any settlement
that does not include as an unconditional term thereof the giving by the
claimant or plaintiff to such indemnified arty of a release from all liability
in respect of a Claim.

10. Indemnification Payments. The indemnification required by this Agreement
shall be made by periodic payments of the amount thereof during the course of
the investigation or defense, as and when bills are received or expense, loss,
damage or liability is incurred.

11. Assignment of Registration Rights. The rights to cause the Company to
register Registrable Securities pursuant to this Agreement may be assigned by
the Holder to a transferee or assignee of such securities who shall, upon such
transfer or assignment, be deemed a Holder under this Agreement; provided that
the Company is furnished with written notice of the name and address of such
transferee or assignee and the Registrable Securities with respect to which the
Registration Rights are being assigned; provided, further, that such assignment
shall be effective only if immediately following such transfer the further
disposition of such securities by the transferee or assignee is restricted under
the Securities Act and that such transferee or assignee is either (a) a member
of the immediate family or a trust for the benefit of any Holder that is an
individual or (b) a transferee or assignee that after the transfer or assignment
holds all of the Registrable Securities.

12. Termination of this Agreement. This Agreement shall terminate with respect
to the Holder when all of the Registrable Securities have been registered as
provided herein.

also be liable for all reasonable counsel's fees and costs of court incurred by

brought in any such county and any claim that any such mediation, arbitration,
suit, action or proceeding brought in such county has been brought in an
