            10.1  Termination Events.  This Agreement may, by written notice
given prior to or at the Closing, be terminated:

            (a)   by either Purchaser or Seller if a material breach of any
      provision of this Agreement has been committed by the other party and
      such breach has not been waived;

            (b)   (i) by Purchaser if any of the conditions in Article VIII has
      not been satisfied as of the Closing Date or if satisfaction of such a
      condition is or becomes impossible (other than through the failure of
      Purchaser to comply with its obligations under this Agreement) and
      Purchaser has not waived such condition on or before the Closing Date; or
      (ii) by Seller, if any of the conditions in Article IX has not been
      satisfied of the Closing Date or if satisfaction of such a condition is
      or becomes impossible (other than through the failure of Seller to comply
      with their obligations under this Agreement) and Seller have not waived

================================================================================
                                       23
<PAGE>   24



otherwise, and the exercise of a right of termination will not be an election
of remedies. If this Agreement is terminated pursuant to Section 10.1, all
further obligations of the parties under this Agreement will terminate, except
that the obligations in Sections 13.5 and 13.7 hereof will survive; provided,
however, that if this Agreement is terminated by a party because of the breach
of this Agreement by the other party or because one or more of the conditions
to the terminating party's obligations under this Agreement is not satisfied as
a result of the other party's failure to comply with its obligations under this
Agreement, the terminating party's right to pursue all legal remedies will
survive such termination unimpaired.

                                   ARTICLE XI

                           Indemnification; Remedies


            11.1  Indemnification and Payment of Damages by Seller.  Seller
shall indemnify and hold harmless Purchaser, the Group Companies, and their
respective directors, officers, employees, agents, consultants, advisors or
other representations, including legal counsel, accountants and financial
advisors, stockholders and controlling persons (collectively, the "Purchaser
Indemnified Persons") for, and will pay to the Purchaser Indemnified Persons
the amount of, any loss, liability, claim, damage (including incidental and
consequential damages) or expense (including costs of investigation and defense
and reasonable attorneys' fees), whether or not involving a third-party claim
(collectively, "Damages"), arising, directly or indirectly, from or in
connection with:

            (a)   any breach of any representation and warranty made by Seller
      in Article IV or Article V hereof or in any document or certificate
      furnished to Purchaser by Seller pursuant to this Agreement, giving full
      effect to any supplement to the Schedules hereto that are delivered by
      Seller to Purchaser prior to the Closing Date with Purchaser's consent in
      accordance with the provisions of Section 6.5 hereof;

            (b)   any breach by Seller of any covenant or obligation of Seller
      in this Agreement;

            (c)   any claim by any person for brokerage or finder's fees or
      commissions or similar payments based upon any agreement or understanding
      alleged to have been made by any such person with either any Seller or
      any Group Company (or any person acting on Seller's or any Group
      Company's behalf) in connection with any of the transactions contemplated
      hereby; and

            (d)   any liability imposed upon any Group Company in respect of
      the termination of employment of Terry Sullivan by a Group Company to the
      extent that such liability exceeds 140,000 Irish pound sterling; provided
      that Purchaser does not cause or permit the Company to settle any claim
      by Mr. Sullivan without the prior written consent of Seller, which

================================================================================
                                       24
<PAGE>   25



      The right to indemnification, payment of Damages or other remedy based on
a breach of representations and warranties, covenants and obligations will not
be affected by any investigation conducted with respect to, or any knowledge
acquired (or capable of being acquired) at any time, whether before or after
the execution and delivery of this Agreement or the Closing Date, with respect
to the accuracy or inaccuracy of or compliance with, any such representation
and warranty, covenant or obligation. The waiver of any condition based on the
accuracy of any representation and warranty, or on the performance of or
compliance with any covenant or obligation, will not affect the right to
indemnification, payment of Damages, or other remedy based on such
representations and warranties, covenants and obligations except to the extent
that such waiver arose when Purchaser permitted Seller to supplement any of the
Schedules hereto in accordance with the provisions of Section 6.5 hereof.

            11.2  Indemnification and Payment of Damages by Purchaser.
Purchaser shall indemnify and hold harmless Seller and their respective
directors, officers, employees, agents, consultants, advisors or other
representatives, including legal counsel, accountants and financial
representatives, stockholders and controlling persons (collectively, the
"Seller' Indemnified Persons") for, and will pay to the Seller' Indemnified
Persons the amount of, any Damages arising, directly or indirectly, from or in
connection with (a) any breach of any representation and warranty made by
Purchaser in Article III hereof or in any certificate furnished by Purchaser to
Seller pursuant to this Agreement; and (b) any breach by Purchaser of any
covenant or obligation of Purchaser in this Agreement.

            11.3  Remedies Not Exclusive; Purchase Price Adjustment.  The
remedies provided in this Article XI shall not be exclusive of or limit any
other remedies that may be available to the Purchaser Indemnified Persons or
the Seller' Indemnified Persons.  Any amounts paid by Seller or Purchaser
pursuant to this Article XI shall be deemed to be adjustments to the Purchase
Price.

            11.4  Time Limitations.  If the Closing occurs, neither Seller nor
Purchaser shall have any liability (for indemnification or otherwise) with
respect to any breach of a covenant or obligation or a representation and
warranty, other than those in Sections 5.2, 5.3, 5.11, 5.12, 5.16 or 5.22
(limited to Taxes), unless on or before the second anniversary of the Closing
Date Purchaser or Seller, as the case maybe, notify Seller or Purchaser of a
claim specifying the factual basis of that claim in reasonable detail to the
extent then known.  A claim by a Purchaser Indemnified Person with respect to
Sections 5.12 or 5.16 may be made at any time prior to the fourth anniversary
of the Closing Date.  A claim by a Purchaser Indemnified Person with respect to
Sections 5.11 or 5.22 (limited to Taxes) may be made at any time prior to the
expiration of the applicable statute of limitations with respect to the matters
set forth in such Sections.  A claim by a Purchaser Indemnified Person with
respect to Sections 5.2 or 5.3 may be made at any time.

            11.5  Limitations on Payments by Seller.  Seller shall have no
liability (for indemnification or otherwise) with respect to any Damages in
respect of a breach of any of the representations and warranties set forth in
Article V hereof if the Damages in respect of such breach are less than 2,000
Irish pound sterling, and Seller shall have no liability respect to


================================================================================
                                       25
<PAGE>   26



any such Damages until the total of all Damages exceeds 50,000 Irish pound
sterling (counting for this purpose claims with respect to which Damages are
less than 2,000 Irish pound sterling), but Seller shall then be liable for the
total amount of such Damages; provided, however, that Seller shall not be
liable for any amount of such Damages in excess of 15,500,000 Irish pound
sterling, excluding for this purpose any amount of such Damages arising from
claims of third parties.  However, the limitations set forth in this Section
11.5 shall not apply to any breach of such representations and warranties of
which any Seller had knowledge at any time prior to the date on which such
representation and warranty was made and Seller shall be jointly and severally
liable for all Damages with respect to such breaches.

            11.6  Procedure for Indemnification--Third Party Claims.

            (a)   Promptly after receipt by a person entitled to
      indemnification hereunder (an "Indemnified Person") of notice of the
      commencement of any proceeding against it, such Indemnified Person shall,
      if a claim is to be made against a person or persons obligated to
      indemnify such Indemnified Person hereunder (the "Indemnifying
      Person(s)"), give notice to the Indemnifying Person(s) of the
      commencement of such proceeding, but the failure to notify the
      Indemnifying Person(s) will not relieve the Indemnifying Person(s) of any
      liability that it (they) may have to such Indemnified Person(s), except
      to the extent that the Indemnifying Person demonstrates that the defense
      of such proceeding is prejudiced by such Indemnifying Person's failure to
      give such notice.

            (b)   If any proceeding referred to in Section 11.6(b) is brought
      against an Indemnified Person and it gives notice to the Indemnifying
      Person(s) of the commencement of such proceeding, the Indemnifying
      Person(s) will, unless the claim involves Taxes, be entitled to
      participate in (but not control) such proceeding at the expense of the
      Indemnifying Person(s); provided, however, that such Indemnified Person
      will have the right to control the defense and any settlement of such
      proceeding unless the Indemnified Person requests in writing that the
      Indemnifying Person(s) assume such defense.  If the Indemnifying
      Person(s) assumes such defense, it (or they) will do so with counsel
      satisfactory to such Indemnified Person and it (or they) will not, from
      and after receipt of the notice of such Indemnified Person's approval of
      counsel selected by the Indemnifying Person(s), as long as they
      diligently conduct such defense, be liable to such Indemnified Person for
      any fees of other counsel or any other expenses with respect to the
      defense of such proceeding, in each case subsequently incurred by such
      Indemnified Person in connection with the defense of such proceeding,
      other than reasonable costs of investigation. If the Indemnifying
      Person(s) assume the defense of a proceeding, (i) it will be conclusively
      established for purposes of this Agreement that the claims made in that
      proceeding are within the scope of and subject to indemnification by the
      Indemnifying Person(s); (ii) no compromise or settlement of such claims
      may be effected by the Indemnifying Person(s) without such Indemnified
      Person's consent unless (A) there is no finding or admission of any
      violation of any applicable statute, rule, regulation, permit issued by
      any governmental authority or Order or any violation of the rights of any
      person and no effect on any other claims that may be made against the


================================================================================
                                       26
<PAGE>   27



      Indemnified Person, and (B) the sole relief provided is monetary damages
      that are paid in full by the Indemnifying Person(s); and (iii) such
      Indemnified Person will have no liability with respect to any compromise
      or settlement of such claims effected without its consent.  The
      Indemnifying Person(s) shall in all events cooperate with such
      Indemnified Person in the defense of such proceedings.

            (c)   Each Indemnifying Person hereby consents to the non-exclusive
      jurisdiction of any court in which a proceeding is brought against any
      Indemnified Person for purposes of any claim that such Indemnified Person
      may have against such Indemnifying Person under this Agreement with
      respect to such proceeding or the matters alleged therein, and agree that
      process may be served on such Indemnifying Person with respect to such a
      claim anywhere in the world.

            11.7  Procedure for Indemnification--Other Claims.  A claim for
indemnification for any matter not involving a third party claim may be
asserted by written notice to the Indemnifying Person(s).


                                  ARTICLE XII

                             Post Closing Covenants

            12.1.  Restrictions on Transfer of Purchase Price Shares.  Seller
covenants that, in addition to any restrictions on the transfer of the Purchase
Price Shares imposed by applicable law, Seller shall not sell, transfer,
encumber or otherwise dispose of any Purchase Price Shares prior to the date
that is twelve months after the Closing Date.  During the period beginning on
such date and ending on the second anniversary of the Closing Date, Seller
covenants that it shall not sell, transfer, encumber or otherwise dispose of an
aggregate number of Purchase Price Shares greater than one half of the Purchase
Price Shares delivered to it by Purchaser.  The foregoing restrictions shall
terminate on the second anniversary of the Closing Date.

            12.2  Manufacture of Veterinary Tablets; Price of Human Products
with Veterinary Applications.  Purchaser covenants that it shall cause the
Company to continue to manufacture for Cross Vetpharm the veterinary tablets
which the Company currently is manufacturing for Cross Vetpharm for a period of
six months after the Closing Date to the extent that orders for such tablets
are placed by Cross Vetpharm with the Company; provided, however, that the
Company shall not be required to manufacture a greater volume of such tablets
than can reasonably be produced using existing machinery.  Cross Vetpharm shall
pay the Company for the manufacture of such tablets, within 60 days after such
amounts are billed by the Company to Cross Vetpharm from time to time, an
amount equal to the higher of (a) the price currently paid by Cross Vetpharm;
or (b) the Company's direct and indirect manufacturing costs.

            Purchaser shall cause the Company, for a period of at least
eighteen months after the Closing Date, to sell to Cross Vetpharm, such
veterinary versions of human antibiotic tablets (i.e. products that are labeled
for veterinary uses), as are ordered by Cross Vetpharm for a price no higher
than the lowest price at which the human

<PAGE>   28



products are sold to the Company's other customers provided that (a) the
foregoing agreement regarding price is subject to the condition that the cost
to the Company of producing veterinary versions of such human products does not
exceed the cost to the Company of producing the human products; and (b) the
aggregate amount of such tablets which the Company shall be required to sell to
Cross Vetpharm shall be 10 million.  The Company shall have the right to cease
selling such tablets to Cross Vetpharm provided that (a) it gives not less than
twelve months prior written notice to Cross Vetpharm of such cessation; and (b)
it shall not have the right to provide such written notice to Corr Vetpharm
prior to then end of the first six months after the Closing Date.

            12.3  Sharing of Personnel.  Seller covenants that it shall
continue to provide to the Company after the Closing Date the services of a
secretary on a half time basis for such period as such services are requested
by the Company; provided, however, that Seller shall not be required to provide
such services for any period longer than three years after the Closing Date.

            12.4  Board Representation.  Purchaser covenants that it shall use
its best efforts to cause Mr. Daniel Tierney to be elected to the Board of
Directors of Purchaser as promptly as practicable after the Closing Date and to
continue to cause him to be elected to such Board for so long us Seller owns
not less than 400,000 Purchase Price Shares; provided, however, that (a) Seller
recognizes that Purchaser has no ability to cause such election to occur given
that the decision to vote for Mr. Tierney's election shall be made by the
shareholders of Purchaser; and (b) Mr. Tierney shall not be entitled to receive
compensation for serving on the Board of Directors of Purchaser.

            12.5  Transfer of Pension Assets.  Schedule 9 to the Ethical Share
Purchase Agreement, which is attached as Annex VIII hereto, shall be applied by
Seller and Purchaser in connection with the transfer of assets relating to the
pension benefits of the Company's employees who participate in the Cross
Vetpharm Group Limited Pension Fund to a new pension fund to be established by
the Company after the Closing Date.  Notwithstanding the provisions of the
first sentence of paragraph 5.1 of Schedule 9, Seller shall procure that such
transfer of assets to such new pension fund is effected.

            (a)   Between the date of this Agreement and the Closing Date,
      Purchaser and Seller will maintain in confidence, and will cause the
      directors, officers, employees, agents and advisors of Purchaser, Seller
      and the Group Companies to maintain in confidence, any written, oral or
      other information obtained in confidence from another party or any Group
      Company in connection with this Agreement or the transactions
      contemplated hereby, unless (i) such information is already known to such
      party or to others not bound by a duty of confidentiality or such
      information becomes publicly available through no fault of such party;
      (ii) the use of such information is necessary or appropriate in making

      statute, rule, regulation, Order or legal process.

            (b)   If the transactions contemplated hereby are not consummated,
      each party will return or destroy as much of such written information as

      shall cause the Group Companies to waive, and Purchaser, on the other

      representatives, as the case may be, to any trade secrets or other
      confidential information of the Group Companies or Purchaser or any of
      its subsidiaries, as the case may be, except to the extent of any
      intentional competitive misuse by Purchaser or Seller, as the case may

are cumulative and not alternative. Neither the failure nor any delay by any
party in exercising any right, power or privilege under this Agreement or the
documents referred to in this Agreement will operate as a waiver of such right,
power or privilege, and no single or partial exercise of any such right, power
or privilege will preclude any other or further exercise of such right, power,
or privilege or the exercise of any other right, power or privilege.  To the
maximum extent permitted by applicable law, (a) no claim or right arising out
of this Agreement or the documents referred to in this Agreement can be

waiver that may be given by a party will be applicable except in the specific
instance for which it is given

matter. This Agreement may not be amended except by a written agreement
executed by the party to be charged with the amendment.

may assign any of its rights under this Agreement without the prior consent of
the other parties except that Purchaser may assign its rights and delegate its
obligations under this Agreement to any Affiliate of Purchaser. Subject to the
preceding sentence, this Agreement shall apply to, be binding in all respects
upon, and inure to the benefit of the successors and permitted assigns of the

equitable right, remedy or claim under or with respect to this Agreement or any
provision of this Agreement. This Agreement and all of its provisions and
conditions are for the sole and exclusive benefit of the parties to this
Agreement and their successors and assigns.

      13.12 Severability.  If any provision of this Agreement is held invalid
or unenforceable by any court of competent jurisdiction, the other provisions
of this Agreement shall remain in full force and effect. Any provision of this
Agreement held invalid or unenforceable only in part shall remain in full force
and effect to the extent not held invalid or unenforceable.

      13.13 Section Headings.  The headings of Articles and Sections in this
Agreement are provided for convenience only and shall not affect its
construction or interpretation.

suit, action or proceeding, and to settle any disputes, which may arise out of

appropriate forum; and (c) agrees that the process by which any suit, action or
proceeding is begun may be served on it by being delivered to the address for
