in a criminal proceeding (excluding traffic violations or similar
misdemeanors) or (ii) been a party to a civil proceeding of a judicial or
administrative body of competent jurisdiction and as a result of such

federal or state securities laws or finding any violation with respect to
such laws.

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

         Abbott acquired 2,782,931 shares of Common Stock (the "Shares") at
an aggregate purchase price of $1,500,000. The source of funds for the
Shares is Abbott's general assets.

ITEM 4.  PURPOSE OF THE ACQUISITION

         Abbott acquired the Shares as an investment and in
connection with its license, research, development, marketing and sale
agreement with the Issuer.

         (a) - (j) At present, Abbott does not have any plans or proposals
which would relate to or result in transactions of the kind described in
paragraphs (a) through (j) of Item 4 of Schedule 13D of the Securities and

                           Page 3 of 6 pages

<PAGE>


right to adopt such plans or proposals subject to compliance with applicable
regulatory requirements.


ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER

         (a)      Abbott is the beneficial owner of the Shares, representing

         (d)      No one other than Abbott is known to have the right to
receive or the power to direct the receipt of dividends from, or the proceeds
from a sale of, the Shares.

         (e)      Not applicable.

ITEM 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
TO SECURITIES OF THE ISSUER

         The summaries of certain terms of the following agreements do not
purport to be complete and are subject to, and are qualified in their
entirety by reference to, all provisions of the agreements and reference is
made to the full text of such agreements which are filed as exhibits to this
statement and are incorporated herein by reference.


                           Page 4 of 6 pages
<PAGE>

         Abbott purchased the Shares pursuant to the terms of a Stock
Purchase Agreement, dated January 27, 2000, by and between Abbott and the
Issuer. In addition, Abbott acquired certain registration rights under a
Registration Rights Agreement, dated January 27, 2000, by and between Abbott
and the Issuer. At any time after the first anniversary of the Registration
Rights Agreement, Abbott may request the Issuer to file a registration
statement registering the resale of the Shares. The Issuer is required to
file a registration statement on Form S-3 within 45 days following such
request. Additionally, subject to certain exceptions under Section 2.2 of
the Registration Rights Agreement, if at any time after the first anniversary
of the Registration Rights Agreement, the Issuer determines to register any
of its securities, the Issuer will give Abbott notice of such registration.
The Issuer will use reasonable efforts to include in such registration Shares
not previously registered or sold to the public with respect to which the
Issuer receives a written request (within 15 days of the notice) to include
in the registration.

         Abbott must provide the Issuer with notice of its intent to sell Shares
pursuant to a registration statement. The Issuer may refuse Abbott the right to
resell Shares pursuant to a registration statement if the Issuer delivers a
certificate to Abbott to the effect that a sale pursuant to the registration
statement could violate federal securities laws. In such an event, the Issuer
shall either use commercially reasonable efforts to promptly amend the
registration statement, if necessary, and take other actions necessary to allow
such sale under the federal securities laws, or exercise the right described in
the next paragraph.

         The Issuer's board of directors in its good faith judgement, after
consultation with counsel, may decline to permit the resale of any Shares for up
to 90 days, if the filing of a registration statement to permit the proposed
sale would adversely affect a pending or scheduled public offering, acquisition,
merger, or similar transaction, or would require disclosure of another material
development before the time it would otherwise be required to be disclosed in a
manner adverse to the Issuer. This right may not be exercised more than twice in
any 12 month period.

                                   EXHIBIT 2

                            STOCK PURCHASE AGREEMENT

         THIS STOCK PURCHASE AGREEMENT (the "Agreement") is made as of the
_____ day of January, 2000, by and between American Biogenetic Sciences,
Inc., a Delaware corporation ("ABS") and Abbott Laboratories, an Illinois
corporation ("Abbott").

         WHEREAS, ABS and Abbott have entered into a Registration Rights
Agreement and an Exclusive License Agreement (the "License Agreement"), both
of even date herewith (collectively the "Alliance Agreements"); and

         WHEREAS, subject to the terms and conditions of this Agreement and
on the basis of the representations and warranties set forth herein, ABS and
Abbott have agreed to the purchase and sale of shares of ABS's Class A common
stock $0.001 par value per share (the "Class A Common Stock").

NOW THEREFORE, ABS and Abbott agree as follows:

         1. PURCHASE AND SALE OF THE SHARES. Subject to the terms and
conditions of this Agreement and on the basis of the representations and
warranties set forth herein, ABS shall issue and sell to Abbott and Abbott
shall purchase from ABS at the Share Closing provided for in SECTION 1.3,
shares of ABS's Class A Common Stock (the "Shares") having an aggregate value
of One Million Five Hundred Thousand Dollars ($1,500,000).

                  1.1 PRICE PER SHARE. The price per share to be paid by
Abbott for each of the Shares (the "Price per Share") shall be equal to the
arithmetic average for the twenty (20) consecutive trading day period ending
on the second day preceding the date of this Agreement of (i) the last sale
price, as reported on the Small Cap Market, of the Class A Common Stock for
the days that it was traded on that market, and (ii) the last sale price
reported on the OTC Bulletin Board, or if no sale is reported that day, the
average of the bid and ask price, of the Class A Common Stock, as reported on
the OTC Bulletin Board for the days when it was primarily traded on that
market.

                  1.2 NUMBER OF SHARES. On the day before the Share Closing,
ABS and Abbott shall determine the number of Shares to be issued, purchased,
and sold pursuant to this Agreement by dividing:

                           (a)      One Million Five Hundred Thousand Dollars
                                    ($1,500,000) by

                           (b)      the Price per Share

<PAGE>

and then rounding down to the nearest whole number the number obtained by
that division.

                  1.3 SHARE CLOSING. The closing of the purchase and sale of
the Shares (the "Share Closing") shall be held at the offices of Brown,
Rudnick, Freed & Gesmer, One Financial Center, Boston, MA 02111, within ten
(10) business days following the date of this Agreement, at 10:00 a.m.
Eastern time, or at such other time and place upon which ABS and Abbott shall
agree.

                  1.4 DELIVERY. At the Share Closing, ABS will issue a
certificate to Abbott registered in Abbott's name representing the number of
Shares being purchased by Abbott against payment to ABS of One Million Five
Hundred Thousand Dollars ($1,500,000). Abbott shall pay the purchase price to
ABS by wire transfer to the bank account of ABS:

                           Name of Bank:    Bank of New York
                           Name of Account: American Biogenetic Sciences, Inc.

                           ABA #:           021-000018

         2. REPRESENTATIONS AND WARRANTIES OF ABS. Except as set forth in the
Schedule of Exceptions attached hereto as EXHIBIT - SECTION 2 (SCHEDULE OF
EXCEPTIONS), ABS hereby represents, warrants, and covenants to Abbott that:

                  2.1      AUTHORITY.

                  (a) ABS has full legal right power and authority to execute
and deliver this Agreement and each of the Alliance Agreements and to
consummate the transactions contemplated hereby and thereby.

                  (b) All corporate action on the part of ABS, its officers,
directors, and stockholders necessary for the execution and delivery of, and
the consummation of the transactions contemplated by, this Agreement and the
Alliance Agreements and the performance of all obligations of ABS hereunder
and thereunder have been taken.

                  (c) Assuming the due and proper execution and delivery by
Abbott, this Agreement and each of the Alliance Agreements, upon execution
and delivery by ABS, constitute legal, valid and binding obligations of ABS,
enforceable in accordance with their respective terms, except as may be
limited by: (i) applicable bankruptcy, insolvency, reorganization or other
laws of general application relating to or affecting the enforcement of
creditors rights generally, (ii) the effect of rules of law governing the
availability of equitable remedies, and (iii) the enforceability of the
indemnity obligations of SECTION 3.1 of the Registration Rights Agreement.

                  (d) The making and performance of this Agreement and the
Alliance Agreements by ABS and the consummation of the transactions
contemplated by this Agreement and the Alliance Agreements will not (i)
violate any provision of the organizational documents of ABS or any of its
subsidiaries, (ii) result in the creation of any lien, charge, security
interest or encumbrance upon any assets of ABS pursuant to the terms or
provisions of, and will not conflict


<PAGE>


with, result in the breach or violation of, or constitute, (either by itself
or upon notice or the passage of time or both), a default under or give rise
to a right of termination, cancellation, or acceleration of any obligation
to, or loss of benefits under any agreement, mortgage, deed of trust, lease,
franchise, licence, indenture, permit, or other instrument to which ABS or
any of its subsidiaries is a party or by which ABS or any of its subsidiaries
or any of their respective properties may be bound or affected, in each case
which would have a material adverse affect on the condition (financial or
otherwise), properties, business, prospects, or results of operations of ABS
and its subsidiaries taken as a whole (a "Material Adverse Effect") or which
would restrict the power of ABS to perform its obligations as contemplated by
this Agreement or the Alliance Agreements or, (iii) violate, to ABS's
knowledge, any statute or any authorization, judgment, decree, order, rule or
regulation of any court or any regulatory body, administrative agency, or
other governmental body applicable to ABS or any of its subsidiaries or any
of their respective properties.

                  (e) Except as disclosed on EXHIBIT - SECTION 2 (SCHEDULE OF
EXCEPTIONS) item 1 hereto, the Company does not have or otherwise contribute
to or participate in any employee benefit plan subject to the Employee
Retirement Income Security Act of 1974.

                  2.2      ORGANIZATION, GOOD STANDING AND QUALIFICATION.

                  (a) ABS and each of its subsidiaries, has been duly
incorporated and is validly existing as a corporation in good standing under
the laws of its jurisdiction of incorporation, with full power and authority
(corporate and other) to own and lease its properties and conduct its
businesses as presently conducted and as proposed to be conducted. ABS and
each of its subsidiaries is duly qualified to do business and in good
standing as a foreign corporation in each jurisdiction in which the ownership
or leasing of properties or the conduct of its business requires such
qualification, except for jurisdictions in which the failure to so qualify
would not have a Material Adverse Effect; and no proceeding has been
instituted in any such jurisdiction, revoking, limiting or curtailing, or
seeking to revoke, limit or curtail such power and authority or qualification.

                  (b) Except as set forth on EXHIBIT - SECTION 2 (SCHEDULE OF
EXCEPTIONS) item 2, ABS has no direct or indirect loans to any partnership,
corporation, joint venture, business association, or other entity, nor does
it own or control, directly or indirectly, any interest in any partnership,
corporation, joint venture, association, or entity which is material to its
business. With respect to any person, the term "subsidiary" means any
corporation more than fifty percent (50%) of whose total interest is,
directly or indirectly, owned by that person. The term "affiliate" when used
to indicate a relationship with a specified person, shall mean a person that
directly, or indirectly through one or more intermediaries, control, or is
controlled by, or is under common control with, such specified person.

                  (c) ABS has delivered to Abbott complete and correct copies
of its Certificate of Incorporation and Bylaws as amended to the date hereof,
and will furnish to Abbott true and correct copies of any amendments thereto
throughout the term of this Agreement.

                  2.3      CAPITALIZATION.

                  (a) The authorized capital stock of ABS consists of
100,000,000 shares of Class A Common Stock, and 3,000,000 shares of Class B
common stock (the "Class B Common Stock"). The Board of Directors has
approved the solicitation of stockholder consents to amend ABS's Certificate
of Incorporation to authorize up to 10,000,000 shares of preferred stock,
$.001 par value per share (the "Preferred Stock"), of which it intends to
designate 6,000 as Series A Preferred Stock.

                  (b) As of January 14, 2000, there were 36,918,510 shares of
Class A Common Stock issued and outstanding, 3,000,000 shares of Class B
Common Stock issued and outstanding and no shares of Preferred Stock issued
and outstanding. All such issued an outstanding shares have been duly
authorized and validly issued and are fully paid and non-assessable and no

statute, the ABS Certificate of Incorporation or Bylaws, or any agreement to
which ABS is a party or by which ABS may be bound.

                  (c) All outstanding shares of ABS's capital stock have been
issued in compliance with applicable federal and state securities laws.

                  (d) ABS has reserved for issuance an aggregate of
approximately 8,248,000 shares of Class A Common Stock for issuance in
connection with options and warrants.

                  (e) Except (i) as set forth in Section 2.3(d) above and on
EXHIBIT - SECTION 2 (SCHEDULE OF EXCEPTIONS) item 3, and (ii) for the right
of Abbott to acquire the Shares under this Agreement, there are no other
options, warrants, conversion privileges, or other contractual rights
presently outstanding or in existence to purchase or otherwise acquire any
authorized but unissued shares of ABS's capital stock or other securities or
the capital stock or other securities of any subsidiary of ABS.

                  2.4 SECTION 203 OF THE DELAWARE GENERAL CORPORATION LAW.
The purchase and sale of the Shares pursuant to this Agreement has been
approved by the Board of Directors of ABS prior to the date of this Agreement
for the purposes of Section 203 of the Delaware General Corporation Law
("Section 203") such that after the date of this Agreement, neither Abbott
nor any of its affiliates will be subject to the restrictions on business
combination transactions set forth in Section 203 with respect to ABS on
account of such purchase.

                  2.5 VALID ISSUANCE OF CLASS A COMMON STOCK. The Shares have
been duly authorized and, when issued, delivered, and paid for in the manner
set forth in this Agreement, will be duly authorized, validly issued, fully
paid and nonassessable, and Abbott shall have good and marketable title to
the Shares free of any liens or restrictions (unless created by Abbott),
other than the restrictions expressly set forth in this Agreement or the
Alliance Agreements or under applicable state and federal securities laws. No
preemptive rights or other rights to subscribe for or purchase exist with
respect to the issuance and sale of the Shares by ABS pursuant to this
Agreement.

                  2.6 GOVERNMENTAL CONSENTS. Other than compliance with the
Securities Act of 1933, as amended (the "Securities Act") and such filings as
may be required to be made with the National Association of Securities
Dealers, no consent, approval order or authorization of, or


<PAGE>


registration, qualification, designation, declaration or filing with, any
federal, state or local governmental authority on the part of ABS is required
in connection with the consummation of the transactions contemplated by this
Agreement.

                  2.7 OFFERING. Subject in part to the truth and accuracy of
Abbott's representations set forth in SECTION 3 of this Agreement, the offer,
sale, and issuance of the Class A Common Stock as contemplated by this
Agreement are exempt from the registration requirements of the Securities
Act, and neither ABS nor any authorized agent acting on its behalf will take
any action hereafter that would cause the loss of such exemption.

                  2.8 LITIGATION. Other than as disclosed in its SEC
Documents, there are no legal or governmental actions, suits or proceedings
pending or, to ABS's knowledge, threatened to which ABS or any of its
subsidiaries is or may be a party or of which property owned or leased by ABS
or any of its subsidiaries is or may be the subject, which actions, suits or
proceedings might, individually or in the aggregate, prevent or adversely
affect the transactions contemplated by this Agreement or result in a
Material Adverse Effect. ABS is not a party or subject to the provisions of
any material injunction, judgment, decree or order of any court, regulatory
body, administrative agency, or other governmental body. There are no
material legal or governmental actions, suits, or proceedings pending or, to
ABS's knowledge, threatened against any executive officers or directors of
ABS.

                  2.9 DISCLOSURE. ABS has provided Abbott with all the
information that Abbott has requested for deciding whether to purchase the
Class A Common Stock. Neither this Agreement, nor any other statements or
certificates made or delivered in connection herewith or therewith contains
any untrue statement of a material fact or omits to state a material fact
necessary to make the statements herein or therein not misleading.

                  2.10     CHANGES.  Since September 30, 1999, except as
otherwise disclosed in the Schedule of Exceptions:

distributions with respect to its capital stock and ABS is not in default in
the payment of principal or interest on any outstanding debt obligations;

                  (d) there has not been any change in the capital stock or,
other than in the ordinary course of business, indebtedness material to ABS;
and

                  (e) there has not been any event, change or development
resulting in or which may reasonably be expected to result in a Material
Adverse Event.

<PAGE>

                  2.11     SEC DOCUMENTS.

                  (a) Since January 1, 1997 ABS has filed each statement,
annual, quarterly, and other report, registration statement and definitive
proxy statement required to be filed (other than preliminary material) by ABS
with the United States Securities and Exchange Commission (the "SEC
Documents"). As of their respective filing dates, the SEC Documents complied
in all material respects with the requirements of the Securities Act or the
Securities Exchange Act of 1934, as amended (the "Securities Exchange Act")
as the case may be, and none of the SEC Documents 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 made therein, in light
of the circumstances in which they were made, not misleading.

                  (b) The audited consolidated financial statements and
unaudited consolidated interim financial statements of ABS included in ABS's
SEC Documents fairly present in all material respects in conformity with
generally accepted accounting principles applied on a consistent basis
(except as may be indicated in the notes thereto), the consolidated financial
position of ABS as of the dates thereof and ABS's consolidated results of
operations and cash flows for the periods then ended. Except as reflected or
reserved against in the consolidated balance sheet of ABS at September 30,
1999 or the Schedule of Exceptions, ABS has no liabilities of any nature
(whether accrued, absolute, contingent or otherwise), except for liabilities
incurred in the ordinary course of business since that date and liabilities
which would not, individually or in the aggregate, have a Material Adverse
Effect.

                  2.12 USE OF PROCEEDS. ABS will use the proceeds from the
sale of the Shares for research and development and for working capital.

         3. REPRESENTATIONS, WARRANTIES AND COVENANTS OF ABBOTT. Abbott
hereby represents, warrants, and covenants to ABS that:

                  3.1 AUTHORIZATION. Abbott has full power and authority to
execute and deliver, and to consummate the transactions contemplated by the
Share Closing and this Agreement. All corporate action on the part of Abbott
necessary for (i) the execution and delivery of, and the consummation of the
transactions contemplated by, this Agreement; and (ii) as of the Share
Closing, the performance of all obligations of Abbott under this Agreement,
has been taken. Assuming the due and proper execution and delivery by ABS,
this Agreement, upon execution and delivery by Abbott, constitutes a legal,
valid and binding obligation of Abbott, enforceable in accordance with its
terms, except as may be limited by (i) applicable bankruptcy, insolvency,
reorganization, or other laws of general application relating to or affecting
the enforcement of creditors rights generally, and (ii) the effect of rules
of law governing the availability of equitable remedies.

                  3.2 PURCHASE ENTIRELY FOR OWN ACCOUNT. This Agreement is
made with Abbott in reliance upon Abbott's representation to ABS, which by
Abbott's execution of this Agreement Abbott hereby confirms, that the shares
to be received by Abbott will be acquired for investment for Abbott's own
account, not as a nominee or agent, and not with a view to the resale or
distribution of any part thereof, and that Abbott has no present intention of
selling, granting any participation in, or otherwise distributing the same.
By executing this Agreement,


<PAGE>


Abbott further represents that Abbott does not have any contract,
undertaking, agreement or arrangement with any person to sell, transfer or
grant participations to such person or to any third person, with respect to
any of the Shares.

                  3.3 GOVERNMENTAL CONSENTS. Other than compliance with the
Securities Act, the Securities Exchange Act, and such filings as may be
required to be made with the Securities and Exchange Commission or the
National Association of Securities Dealers, no consent, approval, order or
authorization of, or registration, qualification, designation, declaration or
filing with, any federal, state or local governmental authority on the part
of Abbott is required in connection with the consummation of the transactions
contemplated by this Agreement.

                  3.4 NO CONSENT. No consent, approval, waiver or other
action by any entity under any material contract, agreement, indenture,
lease, instrument, or other document to which Abbott is a party or by which
it is bound is required or necessary for the execution, delivery and
performance of, or the consummation of the transactions contemplated by, this
Agreement by Abbott.

                  3.5 DISCLOSURE OF INFORMATION. Abbott believes it has
received all the information it considers necessary or appropriate for
deciding whether to purchase the Shares. Abbott further represents that it
has had an opportunity to ask questions and receive answers from ABS
regarding the terms and conditions of the offering of the Shares and the
business, properties, prospects, and financial condition of ABS. The
foregoing, however, does not limit or modify the representations and
warranties of ABS in SECTION 2 of this Agreement or the right of Abbott to
rely on those representations and warranties.

                  3.6 INVESTMENT EXPERIENCE. Abbott is an investor in
securities of companies in the development stage and acknowledges that it is
able to fend for itself, can bear the economic risk of its investment, and
has such knowledge and experience in financial or business matters that it is
capable of evaluating the merits and risks of the investment in the Shares.
Abbott has not been organized for the purpose of acquiring the Shares.

                  3.7 RESTRICTED SECURITIES. Abbott understands that the
Shares it is purchasing are characterized as "restricted securities" under
the federal securities laws inasmuch as they are being acquired from ABS in a
transaction not involving a public offering and that under such laws and
applicable regulations such securities may be resold without registration
under the Securities Act only in certain limited circumstances. In this
connection, Abbott represents that it is familiar with Securities and
Exchange Commission Rule 144, as presently in effect, and understands the
resale limitations imposed thereby and by the Securities Act.

                  3.8      LEGENDS.

                  (a) Each certificate or instrument representing Shares
shall bear legends in substantially the following forms:

                  "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                  REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE "SECURITIES
                  ACT") AND ARE "RESTRICTED SECURITIES" AS DEFINED


<PAGE>


                  IN RULE 144 PROMULGATED UNDER THE SECURITIES ACT. THE
                  SECURITIES MAY NOT BE SOLD OR OFFERED FOR SALE OR OTHERWISE
                  DISTRIBUTED EXCEPT (I) IN CONJUNCTION WITH AN EFFECTIVE
                  REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE
                  SECURITIES ACT, OR (II) IN COMPLIANCE WITH RULE 144, OR
                  (III) PURSUANT TO AN OPINION OF COUNSEL SATISFACTORY TO THE
                  ISSUER OF THESE SECURITIES THAT SUCH REGISTRATION OR
                  COMPLIANCE IS NOT REQUIRED AS TO SUCH SALE, OFFER OR
                  DISTRIBUTION".

                  (b) The certificate shall also bear any other legends
required by Delaware law or applicable blue sky or state securities laws.

Except as provided in the Registration Rights Agreement, ABS need not
register a transfer of any of the Shares and may also instruct its transfer
agent not to register a transfer of any Shares, unless the conditions
specified in the foregoing legends are satisfied to the extent applicable.

                  3.9 ACCREDITED INVESTOR. Abbott is an "accredited investor"
within the meaning of Securities and Exchange Commission Rule 501 of
Regulation D, as now in effect.

as a dividend or other distribution with respect to such common stock.

         2.       REGISTRATION. ABS covenants and agrees as follows:

                  2.1        REGISTRATION RIGHTS - GENERALLY. At any time
after the first anniversary of this Agreement, Abbott may request ABS to file
a Registration Statement registering the resale of the Shares. Within
forty-five (45) days following such request, ABS shall prepare and file a
Registration Statement on Form S-3 (or such other short form registration
statement as is then available) and any related qualification or compliance
with respect to all of the Shares so as to permit or facilitate the sale and
distribution of all of the Shares. ABS agrees to use reasonable commercial
efforts to cause the Registration Statement to be declared effective as soon
as practicable after filing, but in any event no later than three (3)
business days after any notification by the SEC of its decision not to review
the Registration Statement or its determination that it has completed its
review of the Registration Statement and will accept an acceleration request.
ABS agrees it will not include any securities of ABS other than the Shares
and will not permit any other person or entity to include any additional
securities in the Registration Statement to be filed pursuant to this SECTION
2.1.

                  2.2        PIGGYBACK REGISTRATION RIGHTS. If, at any time
after the first anniversary of this Agreement, ABS shall determine to
register any of its securities, either for its own account or the account of
a security holder or holders exercising their respective registration rights,
other than (i) a registration relating solely to employee benefit plans on
Form S-8 (or a similar successor form), or (ii) a registration on Form S-4
(or a similar successor form) relating solely to a transaction subject to
Rule 145 under the Securities Act, ABS will promptly give Abbott written
notice thereof, and subject to the terms of SECTION 2.3 below, use its
reasonable efforts to include in such registration (and any related
qualification under blue sky laws or other compliance), and in any
underwriting involved therein, all Registrable Securities specified in a
written request to ABS made within fifteen (15) business days after the
receipt of such written notice by Abbott.

                  2.3        UNDERWRITING.

                             (a)  If the registration of which ABS gives
                                  notice pursuant to SECTION 2.2 is for a
                                  registered offering involving an
                                  underwriting, then Abbott's right to
                                  registration shall be conditioned upon
                                  Abbott's participation in the underwriting
                                  and the inclusion of Abbott's Registrable
                                  Securities in the underwriting to the extent
                                  provided in this Agreement. Abbott (together
                                  with ABS and the holders of other securities
                                  of ABS distributing their securities through
                                  that underwriting (such other holders being
                                  termed the "Other Holders")) shall enter
                                  into an underwriting agreement in customary


                                      -2-

                                  form with the representative of the
                                  underwriter or underwriters selected by ABS.

                             (b)  Notwithstanding any other provision of this
                                  SECTION 2, if the representative of the
                                  underwriters advises ABS in writing that
                                  marketing factors require a limitation on
                                  the number of shares to be underwritten,
                                  then ABS shall so inform Abbott and the
                                  Other Holders. The number of shares of ABS
                                  common stock being sold by ABS for its own
                                  account shall not be reduced by operation of
                                  this SECTION 2.3. The number of shares of
                                  Registrable Securities held by Abbott and
                                  the Other Holder(s) that may be included in
                                  the underwriting (in addition to those being
                                  sold by ABS for its own account) shall be
                                  allocated among Abbott and the Other Holders
                                  in proportion (as nearly as practicable) to
                                  the amount of Registrable Securities owned
                                  by each such holder.

                             (c)  Any holder which does not agree to the terms
                                  of the such underwriting shall be excluded
                                  from that underwriting by written notice
                                  from ABS or the underwriter. Any Registrable
                                  Securities or other securities excluded or
                                  withdrawn from that underwriting shall be
                                  withdrawn from the registration.

                  2.4        REGISTRATION EXPENSES. ABS shall pay all
"registration expenses" (as defined below) in connection with any
registration, qualification or compliance under this Agreement. Abbott shall
pay all "selling expenses" (as defined below). The term "registration
expenses" shall mean all expenses, except for selling expenses, incurred by
ABS in complying with the registration provisions of this Agreement,
including, without limitation, all registration, qualification and filing
fees, printing expenses, escrow fees, fees and disbursements of counsel for
ABS, accounting fees, blue sky fees and expenses, and the expense of any
attest service incident to or required by any such registration. The term
"selling expenses" shall mean all selling commissions, underwriting fees and
stock transfer taxes applicable to the Shares and all fees and disbursements
of counsel for Abbott.

                  2.5        OBLIGATIONS OF ABS. In the case of a
registration effected by ABS pursuant to this SECTION 2, ABS will use
reasonable efforts to:

                             (a)  keep such registration effective until the
                                  earliest of:

                                  (i)       such date as all of the Shares
                                            have been sold, or

                                  (ii)      if ABS is not then eligible to
                                            effect such registration on
                                            Form S-3 (or a similar successor
                                            form), one hundred and twenty
                                            (120) days after the effective date
                                            of the Registration Statement, or

                                  (iii)     the termination of the registration
                                            rights pursuant to SECTION 2.9
                                            hereof.

                                  used in connection with the Registration
                                  Statement as may be necessary to comply with
                                  the provisions of the Securities Act with
                                  respect to the disposition of all securities
                                  covered by the Registration Statement;

                             (c)  furnish such number of prospectuses,
                                  prospectus supplements, and other documents
                                  incident thereto, including any amendment of
                                  or supplement to the prospectus, as Abbott
                                  from time to time may reasonably request;

                                  on which similar securities issued by ABS
                                  are then listed or quoted;

                             (e)  provided a transfer agent and registrar for
                                  all Registrable Securities registered
                                  pursuant to the Registration Statement and a
                                  CUSIP number for all such Shares;

                                  the SEC; and

                             (g)  file the documents required of ABS and
                                  otherwise use reasonable efforts to maintain
                                  requisite blue sky clearance in:

                                  (i)       all jurisdictions in which any of
                                            the Shares are originally sold; and

                                  (ii)      all other states specified in

                                            this clause (ii), however, that ABS
                                            shall not be required to qualify to
                                            do business or consent to service
                                            of process in any state in which it
                                            is not now so qualified or has not
                                            so consented.

                  2.6        SELLING PROCEDURES.

                             (a)  In the event Abbott intends to sell Shares
                                  pursuant to a Registration Statement, Abbott
                                  shall give ABS five (5) business days notice
                                  of its intent to sell in reliance on such
                                  Registration Statement (the "Notice of
                                  Sale"). ABS may refuse to permit Abbott to
                                  resell any Shares pursuant to the
                                  Registration Statement; provided, however,
                                  that in order to exercise this right, ABS
                                  must


                                      -4-

                                  deliver a certificate in writing within
                                  three (3) business days following the Notice
                                  of Sale to Abbott to the effect that a sale
                                  pursuant to the Registration Statement in
                                  its then current form could constitute a
                                  violation of the federal securities laws. In
                                  such an event, ABS shall either (i) use
                                  commercially reasonable efforts to promptly
                                  amend the Registration Statement, if
                                  necessary, and take all other actions
                                  necessary to allow such sale under the
                                  federal securities laws, and shall notify
                                  Abbott promptly after it has determined that
                                  such sale has become permissible under the
                                  federal securities laws, or (ii) exercise
                                  its right under paragraph (b) below to delay
                                  the sale.

                             (b)  If in the good faith judgment of the Board
                                  of Directors of ABS, after consultation with
                                  counsel, the filing of a Registration
                                  Statement or an amendment thereto or
                                  prospectus supplement so as permit the
                                  proposed sale without a violation of
                                  securities laws would materially adversely
                                  affect a pending or scheduled public
                                  offering, or an acquisition, merger, or
                                  similar transaction, or negotiations of
                                  either of the foregoing, or would require
                                  the disclosure of another material
                                  development prior to the time it would
                                  otherwise be required to be disclosed in a
                                  manner adverse to the best interests of ABS,
                                  then it may decline to permit the resale of
                                  any Shares pursuant to the Registration
                                  Statement for up to a maximum of ninety (90)
                                  days, provided that it may not exercise this
                                  right more than twice in any twelve (12)
                                  month period. Abbott hereby covenants and
                                  agrees that it will not sell any Shares
                                  pursuant to the Registration Statement
                                  during the periods sales in reliance upon
                                  the Registration Statement are prohibited as
                                  set forth in this SECTION 2.6.

                  2.7        INFORMATION FROM ABBOTT. It shall be a condition
precedent to the obligations of ABS to take any action pursuant to SECTION 2
of this Agreement with respect to the Shares that Abbott shall furnish to ABS
such information as ABS may reasonably request, including information
regarding Abbott, the Shares held by it, the intended method of disposition
of such securities, and such other information as required to effect the
registration of the Shares.

                  2.8        ASSIGNMENT OF REGISTRATION RIGHTS. The right to
cause ABS to register the Shares pursuant to this Agreement may be assigned
by Abbott to a transferee of the Shares only if:

                             (a)  ABS is, prior to such transfer, furnished
                                  with written notice of the name and address
                                  of such transferee and the Shares with
                                  respect to which such registration rights are
                                  being assigned and a copy of a duly executed
                                  written instrument in form reasonably
                                  satisfactory to ABS by which such transferee
                                  assumes all of the obligations and


                                      -5-

                                  liabilities of its transferor hereunder and
                                  agrees itself to be bound hereby;

                             (b)  immediately following such transfer the
                                  disposition of the Shares by the transferee
                                  is restricted under the Securities Act;

                             (c)  such assignment includes all of the Shares
                                  then held by Abbott; PROVIDED, HOWEVER, that
                                  such share limitation shall not apply to
                                  transfers by Abbott to its affiliates if all
                                  such transferees or assignees agree in
                                  writing to appoint a single representative as
                                  their attorney-in-fact for the purpose of
                                  receiving any notices and exercising their
                                  rights under this Agreement; and

                             (d)  Abbott guarantees the performance of the
                                  transferee of its obligations under this
                                  Agreement.

                  2.9        TERMINATION OF REGISTRATION RIGHTS. The
registration rights provided in this Agreement shall terminate if Abbott may
sell all of the Shares pursuant to Rule 144 in any three (3) month period.
Upon the termination of registration rights pursuant to this SECTION 2.9, ABS
may withdraw the Registration Statement, or any portion thereof, covering the
Shares.

                  2.10       REPORTS UNDER SECURITIES EXCHANGE ACT OF 1934.
With a view to making available to Abbott the benefits of Rule 144
promulgated under the Securities Act and any other rule or regulation of the
SEC that may at any time permit Abbott to sell securities of ABS to the
public without registration or pursuant to a registration on Form S-3, ABS
agrees to:

                             (a)  make and keep public information available,
                                  as those terms are understood and defined in
                                  SEC Rule 144, at all times;

                             (b)  file with the SEC in a timely manner all
                                  reports and other documents required of ABS
                                  under the Securities Act and the Exchange
                                  Act; and

                             (c)  furnish to Abbott, so long as Abbott owns
                                  any Shares, forthwith upon request (i) a
                                  written statement by ABS that it has complied
                                  with the reporting requirements of SEC
                                  Rule 144, the Securities Act and the Exchange
                                  Act, or that it qualifies as a registrant
                                  whose securities may be resold pursuant to
                                  Form S-3, (ii) a copy of the most recent
                                  annual or quarterly report of ABS and such
                                  other reports and documents so filed by ABS,
                                  and (iii) such other information as may be
                                  reasonably requested in availing Abbott of
                                  any rule or regulation of the SEC that
                                  permits the selling of any such securities
                                  without registration or pursuant to such form.

         3.       INDEMNIFICATION AND CONTRIBUTION

                  3.1        INDEMNIFICATION BY ABS. ABS agrees to indemnify
and hold harmless Abbott, each of Abbott's directors, officers and U.S.
wholly-owned subsidiaries, and each person, if any, who controls Abbott
within the meaning of the Securities Act or the Exchange Act, from and
against any losses, claims, damages or liabilities (or actions or proceedings
in respect thereof) to which they may become subject (under the Securities
Act or otherwise) insofar as such losses, claims, damages or liabilities (or
actions or proceedings in respect thereof) arise out of, or are based upon
any untrue statements of a material fact contained in (or upon the omission
of a material fact from) a Registration Statement delivered or circulated by
Abbott in connection with a sale of ABS securities by Abbott, or arise out of
any failure by ABS to fulfill any undertaking included in the Registration
Statement, and ABS will, as incurred reimburse Abbott and such persons for
any legal or other expenses reasonably incurred in investigating, defending
or preparing to defend any such action, proceeding or claim; provided,
however, that ABS shall not be liable in any such case to the extent that
such loss, claim damage or liability arise out of, or is based upon (i) an
untrue statement made in (or upon the omission of a material fact from) such
Registration Statement in reliance upon and in conformity with written
information furnished to ABS by or on behalf of Abbott specifically for use
in preparation of the Registration Statement, (ii) the failure of Abbott to
comply with the covenants or agreements contained in SECTION 2.6 hereof, or
(iii) any untrue statement or omission in any prospectus that is corrected in
any subsequent prospectus that was delivered to Abbott prior to the pertinent
sale or sales by Abbott.

                  3.2        INDEMNIFICATION BY ABBOTT. Abbott agrees to
indemnify and hold harmless ABS, each of ABS's directors and officers, and
each person, if any, who controls ABS within the meaning of the Securities
Act or the Exchange Act, from and against any losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) to which they may
become subject (under the Securities Act or otherwise) insofar as such
losses, claims, damages or liabilities (or actions or proceedings in respect
thereof) arise out of, or are based upon: (i) either an untrue statement made
in or the omission of a material fact from such Registration Statement in
reliance upon and in conformity with written information furnished to ABS by
or on behalf of Abbott specifically for use in preparation of the
Registration Statement, (ii) the failure of Abbott to comply with the
covenants or agreements contained in SECTION 2.6 hereof, or (iii) any untrue
statement or omission in any prospectus that is corrected in any subsequent
prospectus that was delivered to Abbott prior to the pertinent sale or sales
by Abbott, and Abbott will, as incurred, reimburse ABS and such persons for
any legal or other expenses reasonably incurred in investigating, defending,
or preparing to defend any such action, proceeding, or claim; provided,
however, that Abbott shall not be liable for any amount in excess of the
amount by which the net amount received by Abbott from the sale of the Shares
to which such loss relates minus the amount of any damages which Abbott has
otherwise been required to pay by reason of such untrue or allegedly untrue
statement or omission or alleged omission

                  3.3        INDEMNIFICATION PROCEDURES. Promptly after
receipt by any indemnified party of a notice of a claim or the beginning of
any action in respect of which indemnity is to be sought against an
indemnifying person pursuant to this SECTION 3, such indemnified person shall
notify the indemnifying person in writing of such claim or of the
commencement of such action and, subject to the provisions hereinafter
stated, in case any such action shall be brought against


                                      -7-
<PAGE>

an indemnified person and the indemnifying person shall have been notified
thereof, the indemnifying person shall be entitled to participate therein,
and, to the extent that it shall wish, to assume the defense thereof, with
counsel reasonably satisfactory to the indemnified person. After notice from
the indemnifying person to such indemnified person of the indemnifying
person's election to assume the defense thereof, the indemnifying person
shall not be liable to such indemnified person for any legal expenses
subsequently incurred by such indemnified person in connection with the
defense thereof; provided, however, that if there exists or shall exist a
conflict of interest that would make it inappropriate in the reasonable
judgment of the indemnified person for the same counsel to present both the
indemnified person and such indemnifying person or any affiliate or associate
thereof, the indemnified person shall be entitled to retain its own counsel
at the expense of such indemnifying person.

                  3.4        CONTRIBUTION. If the indemnification provided
for in this SECTION 3 is unavailable to or insufficient to hold harmless an
indemnified party under SECTION 3.1 or 3.2 above in respect of any losses,
claims, damages, or liabilities (or actions or proceedings in respect
thereof) referred to therein, then each indemnifying party shall contribute
to the amount paid or payable by such indemnified party as a result of such
losses, claims, damages, or liabilities (or actions in respect thereof) in
such proportion as is appropriate to reflect the relative fault of ABS on one
hand and Abbott on the other in connection with the statements or omissions
which resulted in such losses, claims, damages, or liabilities (or actions in
respect thereof), as well as any other relevant equitable considerations. The
relative fault shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact related to information
supplied by ABS on one hand or Abbott on the other and the parties' relative
intent, knowledge, access to information, and opportunity to correct or
prevent such statement or omission. ABS and Abbott agree that it would not be
just and equitable if contribution pursuant to this SECTION 3.4 were
determined by PRO RATA allocation or by any other method of allocation which
does not take account of the equitable considerations referred to above in
this SECTION 3.4. The amount paid or payable by an indemnified party as a
result of the losses, claims, damages, or liabilities (or actions in respect
thereof) referred to above in this SECTION 3.4 shall be deemed to include any
legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.

                  3.5        CONTINUING OBLIGATIONS. The obligations of ABS
and Abbott under this SECTION 3 shall survive the completion of the offering
of the Shares pursuant to the Registration Statement and shall be in addition
to any liability that ABS and Abbott may otherwise have.

         4.       MISCELLANEOUS.

                  4.1        SURVIVAL OF WARRANTIES. The warranties,
representations and covenants of ABS and Abbott contained in or made pursuant
to this Agreement shall survive the execution and delivery of this Agreement.

                  4.4        DELAY AND WAIVER. No delay on the part of either
party in exercising any right under this Agreement shall operate as a waiver

this Agreement shall not be construed as a waiver of a subsequent breach or
failure of the same term or condition or a waiver of any other term or
condition contained in this Agreement.
