                                             (i) As soon as practicable, but in
                  no event later than (A) December 31, 2000 with respect to the
                  Earnout Period ending September 30, 2000 and (B) December 31,
                  2001 with respect to the Earnout Period ending September 30,
                  2001, Purchaser will cause to be prepared and delivered to the
                  Seller Representatives an audited balance sheet and the
                  related audited statements of income and changes in
                  shareholder equity of ICTI as of the end of each of the
                  Earnout Periods (collectively, the "Earnout Financial
                  Statements"). The Earnout Financial Statements shall be
                  prepared by Purchaser in accordance with GAAP.

                                             (ii) Upon the completion of the
                  Earnout Financial Statements for each of the Earnout Periods,
                  a copy thereof shall be delivered to the Seller
                  Representatives together with Purchaser's calculation of the
                  Earnout Payment for such Earnout Period, if any, and the
                  components of such calculation, including its calculation of
                  NIBT and Operational Profit for such Earnout Period (the
                  "Earnout Statement"). Sellers' Accountant shall have the
                  right, for a period of twenty (20) days following its receipt
                  thereof to review the Earnout Financial Statements, the
                  related work papers and the Earnout Statement to determine
                  whether the Earnout Financial Statements and the Earnout
                  Statement were prepared in accordance with GAAP and the terms
                  of this Agreement. If, following such review, Sellers'
                  Accountant determines that the Earnout Financial Statements
                  and the Earnout Statement were not prepared in accordance with
                  GAAP and the terms of this Agreement, it shall so notify the
                  Seller Representatives and Purchaser. For a period of ten (10)
                  days following the receipt of such notice, Purchaser and
                  Sellers' Accountant shall attempt to resolve any such dispute
                  with respect to the Earnout Financial Statements and the
                  Earnout Statement. If, at the expiration of such ten (10) day
                  period, Purchaser and Sellers are not able to resolve such
                  disputes, they shall each notify the Seller Representatives of
                  their inability to resolve their dispute within the three (3)
                  day period immediately following the expiration of such ten
                  (10) day period, whereupon Purchaser and the Seller
                  Representatives

                                       19
<PAGE>   28
                  shall promptly submit to the Philadelphia, Pennsylvania office
                  of any "big five" firm of independent certified public
                  accountants (other than Purchaser's Accountant and Sellers'
                  Accountant) (the "Accounting Arbitrator"), which Accounting
                  Arbitrator shall resolve all matters in dispute with respect
                  to the Earnout Financial Statements and the Earnout Statement
                  within the thirty (30) day period immediately following such
                  submission and whose determination shall be final, binding and
                  conclusive upon Purchaser and the Sellers. The fees of the
                  Accounting Arbitrator shall be borne equally by Purchaser and
                  the Sellers; provided, however, that the fees paid or payable
                  to such Accounting Arbitrator shall not be treated as an
                  expense of ICTI for the calculation of Operational Profit
                  pursuant to this Agreement. The scope of the Accounting
                  Arbitrator's review shall be limited to only those matters in
                  dispute with respect to the Earnout Financial Statements and
                  the Earnout Statement.

                                    (e)      Subject to Paragraph 2.2(g) below,
         forty percent (40%) of each Earnout Payment will be payable in cash and
         shall be (i) allocated among each of the Sellers in accordance with the
         respective percentages set forth opposite their names on Schedule
         2.2(a) and (ii) paid by means of a wire transfer of immediately
         available funds to an account or accounts designated by the Seller
         Representative in writing at least three (3) business days prior to the
         applicable Supplemental Closing.

                                    (f)      Subject to Paragraph 2.2(g) below,
         sixty percent (60%) of each Earnout Payment will be payable by means of
         transfer to the Sellers of shares of Galen Stock and, accordingly,
         Purchaser shall take such actions as are necessary to cause Galen
         Holdings to issue to the Sellers at the applicable Supplemental Closing
         such number of shares of Galen Stock as shall equal the quotient
         obtained by dividing (i) sixty percent (60%) of the amount of the
         Earnout Payment by (ii) the Average Mid Price, which Galen Stock shall
         be issued to the Sellers, pro rata, in accordance with the respective
         percentages set forth opposite their names on Schedule 2.2(a);
         provided, however, that such quotient shall be rounded up to the
         nearest whole number of shares of Galen Stock.

                                    (g)      Purchaser shall have the right, in
         its sole discretion, to increase the cash portion of each Earnout
         Payment, and to

                                       20
<PAGE>   29
         make a corresponding decrease in the number of shares of Galen Stock
         payable to Sellers on account of any such Earnout Payment, to such
         percentage of the Earnout Payment as it desires.

                           2.3      Closing Deliveries. At the Closing:

                                    (a)      the Sellers will deliver, or cause
         to be delivered, to Purchaser:

                                             (i) the original stock certificates
                  representing all of the Purchased Shares accompanied by duly

                  3.       REPRESENTATIONS AND WARRANTIES OF SELLERS

                  The Sellers hereby jointly and severally represent and warrant
to Purchaser as follows:

                           3.1      Organization and Good Standing; No
Subsidiaries, Etc. ICTI is a corporation duly organized, validly existing, and
in good standing under the laws of the State of New Jersey, with full corporate
power and authority to (a) conduct its Business as it is now being conducted,
(b) own or use the property and assets that it owns or uses, and (c) perform all
its obligations under all Contracts to which it is a party. ICTI is duly
qualified to do business as a foreign corporation and is in good standing under
the laws of each state or other jurisdiction in which either the ownership or
use of the properties or assets owned or used by it, or the nature of the
activities conducted by it, requires such qualification and in which the failure
to so qualify would have a Material Adverse Effect. Except as set forth on
Schedule 3.1, ICTI does not, directly or indirectly, (i) own, of record or
beneficially, any outstanding voting securities or other equity interests in any
other Person or (ii) otherwise control any other Person.

                                    (a)      The ICTI Stock consists of ten
         million (10,000,000) authorized shares of no par common voting stock of
         which, as of the date hereof, five million five hundred eleven thousand
         three hundred sixty-four (5,511,364) shares are issued and outstanding.

                                    (b)      All of the Purchased Shares are
         duly authorized, validly issued and outstanding, fully paid and
         non-assessable. No shares of ICTI Stock are reserved for any purpose.
         Except as set forth on Schedule 3.2(b), each of the Sellers (i) owns
         beneficially and of record the number of Purchased Shares set forth
         opposite their name on Schedule 1.1.72, and (ii) has good and
         marketable title to such Purchased Shares and owns such Purchased
         Shares free and clear of all Encumbrances. The Purchased Shares
         constitute one hundred percent (100%) of all of the issued and
         outstanding shares of ICTI Stock. Except for the Contemplated
         Transactions and as otherwise set forth on Schedule 3.2(b), none of the
         Sellers nor ICTI has any commitment or obligation to redeem, buy,
         issue, deliver or sell any shares of ICTI Stock or any securities or
         obligations convertible into or exchangeable for, or giving any Person
         any right or option to put, or subscribe for, purchase or otherwise
         acquire from ICTI or the Sellers, any shares of ICTI Stock, and no such
         securities or obligations are issued or outstanding.

                           3.3      Authority; No Conflict.

                                    (a)      Each Seller has all requisite legal
         right, power and authority to execute and deliver this Agreement and
         the Related Agreements to which such Seller is a party and to fully
         perform such Seller's obligations hereunder and thereunder. This
         Agreement constitutes the legal, valid, and binding obligation of the
         Sellers, enforceable against the Sellers in accordance with its terms.
         Upon the execution and delivery by the Sellers of the Related
         Agreements to which the Sellers are a party, such Related Agreements
         will constitute the legal, valid, and binding obligations of the
         Sellers, enforceable against the Sellers in accordance with their
         respective terms.

                                    (b)      Except as set forth in Schedule
         3.3(b), neither the execution, delivery and performance of this

                  or to cancel or terminate any Material Contract (including,
                  without limitation, any material Lease) to which ICTI is a
                  party or by which ICTI or any of its properties are bound; or

                                    (a)      Schedule 1.1.35 contains true and
         complete copies of the Financial Statements. The Financial Statements

         position and the results of operations and changes in stockholders'
         equity of ICTI as at the respective dates of and for the periods
         referred to in such Financial Statements, all in conformity with GAAP
         consistently applied throughout the periods involved. No financial
         statements of any Person other than ICTI are required by GAAP to be
         included in the Financial Statements.

         Statements"). Except as may be otherwise noted therein and subject to
         year-end audit adjustments (which, in the aggregate, are not material),
         the Interim Financial Statements are true and correct and present
         fairly, in all respects, in accordance with GAAP applied on a basis
         consistent with the Financial Statements (subject to year-end
         adjustments and except for the absence of detailed notes or other
         exceptions customary for interim financial statements), the financial
         position and the results of operations and changes in stockholders'
         equity of ICTI as at the Interim Balance Sheet Date and for the period
         then ended.

         stock record books, and other records of ICTI are complete and correct

                                    (a)      ICTI does not own in fee any real
         property or interests in real property. Schedule 1.1.55 sets forth a
         true and complete list of all real property leased by ICTI. ICTI has
         (i) good and marketable title to all of its property and assets
         (whether tangible or intangible and including all Intellectual
         Property), which property and assets will not, at the Closing, be
         subject to any Encumbrance other than the Permitted Encumbrances
         identified on Schedule 1.1.67 that specifically relate to such other
         property and assets and (ii) a valid leasehold interest in the Leased
         Personal Property and the Leased Real Property pursuant to the
         respective Leases subject, however, to the Permitted Encumbrances
         identified on Schedule 1.1.67 that specifically relate to the Leased
         Personal Property and Leased Real Property.

                                    (b)      Except as set forth on Schedule
         3.6(b), (i) the Leased Real Property, the use and occupancy thereof by
         ICTI, and the conduct thereon and therein of the Business does not
         violate in any material

                                       28

         respect any applicable Legal Requirement relating to any Leased Real
         Property consisting of requirements applicable to licenses and permits
         and requirements consisting of building codes, deed restrictions, or
         any zoning, subdivision or other land use or similar laws; (ii) ICTI
         has received no notice of any material violation of any applicable
         Legal Requirements relating to any Leased Real Property (including
         requirements applicable to licenses and permits and requirements
         consisting of building codes, deed restrictions or any zoning,
         subdivision or other land use or similar laws which relate to the
         Leased Real Property, the use and occupancy thereof by ICTI or the
         conduct therein and thereon of the Business); (iii) there are no
         existing or pending, and to the Knowledge of the Sellers no Threatened,
         (A) requests, applications or proceedings to alter or restrict the
         zoning or other use restrictions applicable to any of the Leased Real
         Property, (B) condemnation proceedings that would affect any of the
         Leased Real Property, or (C) public improvements that would result in
         any material charge or Tax being levied or assessed against, or would
         result in the creation of any material Encumbrance upon, any of the
         Leased Real Property; and (iv) to the Knowledge of the Sellers, there
         are no other developments or conditions affecting any of the Leased
         Real Property which would be reasonably likely to materially interfere
         with any present use of the Leased Real Property.

         of any products or services that ICTI has sold, leased or produced or,
         to the Knowledge of Sellers, any basis for any present or future
         Proceeding against ICTI giving rise to any such Liability and (ii) no
         material claim in respect thereof has been asserted by any Person.
         Except as set forth in Schedule 3.7, no product produced, sold or

         individuals or property that occurred by reason of the ownership,

         performed by, ICTI or, to the Knowledge of Sellers, any basis for any
         present or future Proceeding against ICTI that

                                       29
<PAGE>   38
         would result in any such Liability to ICTI and (ii) no claim in respect
         thereof has been asserted by any Person.

         3.8(a), (i) ICTI has filed or caused to be filed all Tax Returns that
         are or were required to be filed by it (taking into account any valid
         extensions of time for filing) pursuant to applicable Legal
         Requirements and (ii) ICTI has paid, or made provision for the payment
         of, all Taxes that have become due and payable by it, regardless of

         are listed in such Schedule 3.8(a) and are being contested in good
         faith and as to which adequate reserves (determined in accordance with
         GAAP) have been provided in the Balance Sheet.

                                    (b)      All Tax Returns filed by ICTI (i)
         were prepared in good faith and in a manner reasonably believed, by
         management of ICTI, to be in accordance with tenable interpretations
         and applications of the Code and any other applicable Legal Requirement
         and (ii) are true and correct in all material respects.

                                    (c)      For federal income tax purposes,
         ICTI is, and has been since the date of its incorporation, properly
         classified as an "S corporation" under Section 1361(a) of the Code and

                                    (d)      Except as set forth on Schedule
         3.8(d), since ICTI's inception, there has been no audit commenced

                           3.9      Employment Agreements; Employee Benefits;
ERISA.

                                    (a)      Schedule 3.9(a) sets forth an
         accurate list of (i) all officers, directors and employees of ICTI and
         (ii) all employment agreements with any such officers, directors and
         employees and the rate of compensation (and the portions thereof
         attributable to salary, bonus and other compensation, respectively) of
         each of such officers, directors or employees as of (A) the first
         payroll date immediately preceding the Balance Sheet Date and (B) the
         last payroll date immediately preceding the date of this Agreement.
         Schedule 3.9(a) includes true, complete and correct copies of any
         existing employment agreements for the officers, directors or employees
         listed on Schedule 3.9(a). Since the Balance Sheet Date and except as
         described in Schedule 3.9(a), there have been no increases in the
         compensation payable or any special bonuses to any officer, director,
         or employee, except ordinary salary increases and bonuses implemented
         on a basis consistent with past practices and bonuses, as described in
         Schedule 3.9(a).

                                    (b)      Schedule 3.9(b) sets forth a
         complete and accurate list of all Employee Benefit Plans, and Schedule
         3.9(b) includes true, complete and correct copies of such Employee
         Benefit Plans, and any agreements, insurance contracts and trusts
         related thereto. Except for the Employee Benefit Plans identified on
         Schedule 3.9(b), ICTI does not sponsor, maintain, contribute to or have
         any material Liability with respect to any Employee Benefit Plan.
         Except as set forth in Schedule 3.9(b), ICTI is not now, nor, to the
         Knowledge of the Sellers, will it as a result of its past activities
         become, liable to the PBGC or to any multiemployer employee pension
         benefit plan under the provisions of Title IV of ERISA. All Employee
         Benefit Plans and the administration thereof comply in all material
         respects with the terms thereof and all applicable provisions of ERISA,
         as well as all other applicable Legal Requirements. As of the Interim
         Balance Sheet Date, all accrued contribution obligations of ICTI with
         respect to any Employee Benefit Plan have either been paid or are

                                       31
<PAGE>   40
         reflected on the Interim Financial Statements as of the Interim Balance
         Sheet Date.

                                    (c)      Except as set forth on Schedule
         3.9(c), all Employee Benefit Plans that are intended to qualify
         (collectively, "Qualified Plans") under Section 401(a) of the Code are,
         and have since their inception been so qualified and have been
         determined by the IRS to be so qualified, and copies of the most recent
         determination letters with respect thereto are attached to Schedule
         3.9(c) and nothing has occurred since the date of such letter that has
         or, to the Knowledge of the Sellers, is reasonably likely to, and the
         consummation of the Contemplated Transactions will not, adversely
         affect such qualification. Except as disclosed on Schedule 3.9(c), all
         reports and other documents required to be filed with the Department,
         the PBGC or the IRS or any other Governmental Body or distributed to
         plan participants or beneficiaries (including actuarial reports, audits
         or tax returns) have been timely filed or distributed, and copies of
         the most recent reports and filings relating thereto are included as a
         part of Schedule 3.9(c). Neither the Sellers, any of the Employee
         Benefit Plans listed in Schedule 3.9(a), nor ICTI has engaged in any
         transaction prohibited under the provisions of Section 4975 of the Code
         or Section 406 of ERISA. No Employee Benefit Plan has incurred an
         accumulated funding deficiency (as defined in Section 412(a) of the
         Code and Section 302(1) of ERISA); and ICTI has not incurred any
         liability for excise tax or penalty due to the IRS, nor any liability
         to the PBGC. Except as set forth on Schedule 3.9(c):

                                             (i) there have been no
                  terminations, partial terminations or discontinuations of
                  contributions to any Qualified Plan without the giving of all
                  notices and the obtaining of all approvals required by
                  applicable Legal Requirements;

                                             (ii) no Employee Benefit Plan
                  listed on Schedule 3.9(a) that is subject to the provisions of
                  Title IV of ERISA has been terminated;

                                             (iii) there have been no
                  "reportable events" (as that phrase is defined in Section 4043
                  of ERISA) with respect to any Employee Benefit Plan listed on
                  Schedule 3.9(a);

<PAGE>   41
                                             (iv) ICTI has not incurred any
                  liability under Section 4062 of ERISA; and

                                             (v) to the Knowledge of the
                  Sellers, no circumstances exist pursuant to which ICTI would
                  have any direct or indirect Liability (including, but not
                  limited to, any Liability to any multiemployer plan or the
                  PBGC under Title IV of ERISA or to the IRS for any excise tax
                  or penalty, or being subject to any statutory lien to secure
                  payment of any such Liability) with respect to any Employee
                  Benefit Plan now or heretofore maintained or contributed to by
                  any Person other than ICTI that is, or at any time was, a
                  member of a "controlled group" (as defined in Section
                  412(n)(6)(B) of the Code) that includes ICTI.

                                    (d)      Except for the vesting of the
         Purchased Options that will occur as a result of the Contemplated
         Transactions, and as otherwise set forth in Schedule 3.9(d), the
         consummation of the Contemplated Transactions will not (i) entitle any
         employee or former employee of ICTI to any payment (whether in the
         nature of severance or otherwise), (ii) increase the amount of
         compensation due to any such employee, (iii) accelerate the time of
         vesting of any compensation, stock incentive or other benefit or (iv)
         result in any "parachute payment" under Section 280G of the Code
         whether or not such payment is considered to be reasonable compensation
         for services rendered.

                                    (e)      Except as described in Schedule
         3.9(e), (i) with respect to each Employee Benefit Plan, (A) all
         contributions required or payments due from ICTI to the date hereof
         have been made or will be timely made and all such amounts have been
         properly recorded on the books of ICTI, and (B) there are no actions,
         suits or claims pending (other than routine claims for benefits) or, to
         the Knowledge of the Sellers Threatened, with respect to such Employee
         Benefit Plan or against the assets or fiduciaries of such Employee
         Benefit Plan and (ii) to the Knowledge of the Sellers, no event has
         occurred as a result of which ICTI or any Employee Benefit Plan would
         be reasonably likely to be subject to any Liability under ERISA, the
         Code or any other Legal Requirement applicable to any Employee Benefit
         Plan.

         3.10(a):

                                             (i) ICTI has complied and is in
                  compliance in all material respects with each Legal
                  Requirement that is applicable to it or to the conduct or
                  operation of the Business or the ownership or use of any of
                  its properties or assets;

                                             (ii) to the Knowledge of the
                  Sellers, no event has occurred or circumstances exist that (A)
                  would constitute or result in a material violation by ICTI of,
                  or a material failure on the part of ICTI to comply with, any
                  Legal Requirement, or (B) would give rise to any material
                  Liability on the part of ICTI to undertake, or to bear all or
                  any portion of the cost of, any remedial action pursuant to
                  any such Legal Requirement; and

                                             (iii) ICTI has not received any

                  regarding (A) any actual, alleged, or potential material
                  violation of, or failure to comply with, any Legal
                  Requirement, or (B) any actual, alleged, or potential material
                  Liability on the part of ICTI to undertake, or to bear all or
                  any portion of the cost of, any remedial action pursuant to
                  any applicable Legal Requirement.

                                    (b)      Schedule 3.10(b) contains a
         complete and accurate list of each material Governmental Authorization
         that is held by ICTI or that otherwise relates to the Business, in each
         case indicating the expiration date thereof, if any. The Governmental
         Authorizations listed in Schedule 3.10(b) constitute all Governmental
         Authorizations required under applicable Legal Requirements to permit
         ICTI's operation of the Business in the manner in which it is currently
         conducted. Each Governmental Authorization listed in Schedule 3.10(b)

                  Sellers, no event has occurred or circumstance exists that (A)
                  would constitute or result directly or indirectly in a

                  term or requirement of any Governmental Authorizations listed
                  in Schedule 3.10(b) or (B) would result in the revocation,

                                             (i) there is no Proceeding that has
                  been commenced by or against ICTI or that, to the Knowledge of

                  adversely affect, the Business or any of ICTI's properties or
                  assets; or

                                             (ii) there is no Proceeding pending
                  that challenges, or that is reasonably likely to have the
                  effect of preventing, materially delaying or rendering illegal
                  any of the Contemplated Transactions; or

                  of, any remedial action pursuant to any such Environmental

         reasonable measures necessary to protect the Intellectual Property

         Intellectual Property to enter the public domain, or taken any action
         which has in any way affected its absolute and unconditional ownership
         of any portion of the Intellectual Property owned by it, or its use of
         any portion of the Intellectual Property licensed by it.

         software solutions that are necessary to address "Year 2000" computer
         systems issues relating to the Business. Accordingly, the computer
         systems of ICTI (including all hardware, workstations and related
         components and date sensitive equipment and all Software (including not
         only the Software owned or used by ICTI internally, but all Software

         any product sold or licensed by, or any service performed by, ICTI) are
         Year 2000 Compliant. The term "Year 2000 Compliant," as used herein,

         only two digits and date fields assigned special values), (iii) have
         the ability to automatically function into and beyond the year 2000

         5. MUTUAL COVENANTS; COVENANTS OF SELLERS

                  5.1 Mutual Covenants Regarding Taxes, Etc.

                                    (i) The Sellers shall be required to, and
         shall have the sole and exclusive authority to, prepare, execute and
         file on behalf of ICTI (A) the federal income Tax Returns to be filed
         on behalf of ICTI for periods ending on or before the Closing Date and

                                       52
<PAGE>   61
         (B) the corresponding state and local income Tax Returns for the State
         of New Jersey and any of the other jurisdictions identified in Schedule
         3.8(c) to be filed on behalf of ICTI for periods ending on or before
         the Closing Date, that will include the gain or loss resulting from the
         "deemed sale" and "deemed liquidation" that will occur (pursuant to
         Treasury Regulation Sections 1.338(h)(10)-1(e)(1) and (2) promulgated
         under the Code) by reason of Purchaser's and the Sellers' election
         pursuant to Section 338(h)(10) of the Code and any Tax pursuant to
         Section 1374 of the Code. All such federal, state and local Tax Returns
         shall be prepared in a manner consistent with the tax accounting
         methods and principles that ICTI has used in its immediately preceding
         tax year to report its income to each relevant taxing authority.
         Subject to the provisions of Section 5.1(a)(iii)(A), the Sellers will
         provide to ICTI a copy of each such Tax Return no less than fifteen
         (15) business days prior to the due date for filing such Tax Return,
         together with payment for all Taxes due, and ICTI will promptly execute
         and timely file such Tax Return, together with the Sellers' payment
         therefor, with the appropriate taxing authority or other Governmental
         Body.

                                    (ii) Purchaser shall promptly notify the
         Seller Representatives in writing upon receipt by Purchaser or ICTI of
         notice of any pending or threatened Tax audits of or assessments
         against ICTI for taxable periods of ICTI ending on or prior to the
         Closing Date and with respect to which Sellers would be reasonably
         likely to have any Liability, whether as the result of ICTI's being
         classified as an S corporation under the Code and any comparable state
         statutes or pursuant to this Agreement. Subject to Sections
         5.1(a)(iii), 5.1(a)(iv), 7.2 and 7.4, the Seller Representatives shall
         have the right, at their own expense, to control any audit or
         determination by any taxing authority or other Governmental Body,
         initiate any claim for refund or amended return, and contest, resolve
         and defend against any assessment, notice of deficiency, or other
         adjustment or proposed adjustment of Taxes for any taxable period
         described in the immediately preceding sentence, and the Sellers shall
         retain all rights with respect to any Tax refunds that may be due or
         payable with regard to any such taxable periods. Purchaser agrees not
         to amend or cause to be amended any income Tax Return filed by

                                       53
<PAGE>   62
         ICTI for taxable periods of ICTI ending on or before the Closing Date
         without obtaining the consent of the Seller Representatives (which
         consent will not be unreasonably withheld or delayed) unless such
         amendment is required to correct a clearly erroneous matter of fact or
         law or Purchaser or ICTI is directed to file such amendment by any
         taxing authority or other Governmental Body. If the Seller
         Representatives consent to Purchaser's request to amend any such
         previously filed Tax Return to correct a matter of fact or law that is
         arguably correct under the standards so imposed by applicable Legal
         Requirements (i.e., reasonable basis, substantial authority, more
         likely than not, etc.), the Sellers shall timely pay any increase in
         Tax liability that the Sellers are required to pay to any taxing
         authority as a result of such amendment and Purchaser shall promptly
         reimburse the Sellers for the amount of any penalty or interest payable
         by them as a result of such increase in Tax.

                                    (iii) In furtherance of the provisions of
         Sections 5.1(a)(i) and 5.1(a)(ii), Purchaser will cooperate fully with
         and, if requested by the Seller Representatives, will (A) appoint one
         or both of the Seller Representatives as duly authorized officers of
         ICTI solely for purposes of executing and filing on behalf of ICTI the
         final Tax Returns referred to in this Section 5.1(a), conducting any
         audits or examinations with respect thereto or any Tax Return with
         respect to which, or as the result of which, the Sellers may have any
         Liability, negotiating and approving all changes or adjustments to such
         Tax Returns or any Tax Return with respect to which, or as the result
         of which, the Sellers may have any Liability, and negotiating,
         approving and executing all agreements (including closing agreements)
         with the appropriate taxing authorities or other Governmental Bodies at
         the conclusion of any such audits or examinations, which shall be
         binding upon ICTI and Purchaser, and (B) join in the filing of all
         final Tax Returns. The Seller Representatives shall have sole and
         exclusive authority with respect to the conduct, negotiation and
         settlement of any such audits or examinations; provided, however, that
         (1) anything to the contrary set forth in this Section 5.1(a)(iii)
         notwithstanding, with respect to any matters that may adversely affect
         the Purchaser or ICTI after the Closing Date, the Seller
         Representatives shall consult with, and consider in good faith, the
         suggestions of ICTI and

                                       54
<PAGE>   63
         Purchaser, and the Seller Representatives shall not settle any such
         matter without Purchaser's written consent, which consent will not be
         unreasonably withheld and (2) nothing set forth in this Section
         5.1(a)(iii) will alter or affect Purchaser's right to receive, or the
         Sellers' obligation to provide, indemnity pursuant to Sections 7.2 or
         7.4. Form 8023 shall be filed together with, and as a part of, each
         such final Tax Return if the filing of Form 8023 is required by any
         applicable Legal Requirement.

                                    (iv) Notwithstanding anything set forth
         herein to the contrary, Purchaser shall have sole and exclusive
         authority with respect to the conduct, negotiation and settlement of
         any examinations or audits arising out of or relating to the Sellers'
         election pursuant to Section 338(h)(10) of the Code (and any comparable
         state statutes) and any Tax under Section 1374 of the Code. The Sellers
         will cooperate fully with Purchaser in connection with any such
         examination or audit.

                           (b) Each of the Seller Representatives and Purchaser,
upon the request of the other party, will, at any time and from time to time,
afford to the other party, or any other Representatives of other party, full and
complete access to the books and records of ICTI (including all accounting,
financial and tax records) as shall be necessary to permit the Sellers and
Purchaser to effectuate the provisions of Section 5.1(a) and, in connection
therewith, Purchaser will make available, or cause to be made available, to the
Seller Representatives, such qualified personnel of ICTI and Purchaser as the
Seller Representatives shall reasonably request to assist in the compilation of
the information necessary to prepare and file the Tax Returns referred to in
Section 5.1(a) as well as may be necessary to respond to any audit that may be
conducted from time to time with respect to such Tax Returns or any other Tax
Returns filed by ICTI on or prior to the Closing Date.

                           (c) Purchaser acknowledges that ICTI has made, and at
or prior to the Closing will make, distributions to the Sellers, to fund
estimated tax payments relating to the income attributable to the Sellers as a
result of ICTI's election to be treated as an S corporation under the Code and
under the laws of the State of New Jersey and the other jurisdictions

                                       55
<PAGE>   64
identified in Schedule 3.8(c), including any such distributions as may be
necessary to fund the estimated tax payments relating to ICTI's income for the
taxable periods ending on or before the Closing Date but not including any
income arising out of or relating to the elections described in Section 5.1(d)
below (all of the distributions described in this Section 5.1(c) shall be
collectively referred to herein as the "Permitted S Corporation Distributions").

                           (d) Purchaser and the Sellers shall make a timely
election under Section 338(h)(10) of the Code and Section 1.338(h)(10)-1 of the
Treasury Regulations promulgated pursuant to the Code, and any corresponding
elections under state or local tax law in the State of New Jersey and in the
other jurisdictions identified in Schedule 3.8(c). Purchaser and the Sellers
shall (i) take, and cooperate with each other to take, all actions necessary and
appropriate (including, without limitation, the preparation, completion and
timely joint filing by Purchaser and the Sellers of Form 8023, and the
preparation, completion and timely filing of such other forms, returns,
elections, schedules and other documents and instruments) to effect, perfect and
preserve a timely Section 338(h)(10) election in accordance with Section
338(h)(10) of the Code and Section 1.338(h)(10)-1 of the Treasury Regulations
promulgated pursuant to the Code, and (ii) report the purchase and sale of the
Purchased Shares, consistent with the election pursuant to Section 338(h)(10)
referred to in this Section 5.1(d) and shall take no position contrary thereto
or inconsistent therewith in any Tax Return, or in any discussion with or any
Proceeding before any taxing authority or other Governmental Body or otherwise.

                           (e) In the event that, in connection with an audit
relating to an election pursuant to Section 338(h)(10) of the Code (and any
comparable state or local statutes), the Sellers' final Tax liability relating
to such election is, after audit or examination, increased above the amounts
reflected on the Tax Returns described in Section 5.1(a)(i) and referred to in
Section 5.1(d), then (i) the Sellers shall pay, when due, any such increased Tax
liability and (ii) the Purchaser shall promptly reimburse the Sellers for the
amount of any penalty or interest payable by them as the result of such increase
in Tax.

                                       56
<PAGE>   65
                  5.2 Investment Representations. Prior to, or concurrently
with, the issuance of any shares of Galen Stock to the Sellers pursuant to
Section 2.3(c), the Sellers shall execute and deliver to Purchaser a letter
addressed to Purchaser and Galen Holdings stating that the Sellers are acquiring
the shares of Galen Stock as an investment, and not with a view to, or for, sale
or transfer in connection with any distribution thereof, or for any sale or
transfer thereof. The Sellers acknowledge that each certificate evidencing
shares of Galen Stock will have endorsed thereon a restrictive legend setting
forth the restrictions referred to in Section 4.6(a).

                  5.3 Subordination of Deferred Payments. The Sellers
acknowledge that the deferred portion of the Purchaser Price described in
Section 2.2(b) and any Earnout Payment to which they may become entitled will be
unsecured and at all times under, subject and subordinate in right of payment
and enforcement to the prior, irrevocable payment in full of all existing or
future Liabilities that may owed to the senior lenders to Purchaser, Galen
Holdings or the consolidated group of corporations of which Purchaser and Galen
Holdings are members. In furtherance of such subordination, the Sellers will,
upon the request of Purchaser or Galen Holdings, promptly execute and deliver to
any or all of the aforementioned senior lenders a subordination agreement in the
standard form prescribed by such senior lenders (which subordination agreement
shall be reasonably acceptable to the Sellers) and will also execute such other
documents and instruments and take such other actions as may be reasonably
necessary to further evidence or effectuate the provisions of this Section 5.6.
Anything to the contrary set forth in this Section 5.3 notwithstanding, no
Seller may refuse to execute the form of subordination agreement referred to in
the immediately preceding sentence unless the terms of such subordination
agreement are expressly inconsistent with the essential terms of subordination
described in the first sentence of this Section 5.3.

         6. COVENANTS OF PURCHASER

                  6.1 Filing of Tax Returns. Purchaser shall prepare, execute
and file within the time periods established by any applicable Legal Requirement
(a) Purchaser's federal income Tax Return for the tax year of Purchaser in which
the Closing occurred and (b) ICTI's federal income Tax Return for the tax year
of ICTI that begins with, and includes, the first day of the tax year of ICTI

                                       57
<PAGE>   66
immediately following the end of the tax year of ICTI for which the final Tax
Returns referred to in Section 5.1(a) are filed.

                  6.2 Change of Fiscal Year of ICTI. Purchaser, as soon as
practicable following the Closing, will take such actions as are necessary to
cause ICTI's fiscal-year for financial reporting and Tax purposes to be changed
to the twelve (12) month period commencing on October 1 of each calendar year
and ending on September 30 of the following calendar year.

                  6.3 Default Rate of Interest. Subject to Purchaser's set-off
rights described in Section 7.9, if Purchaser fails to pay either (a) the
deferred portion of the Purchase Price described in Section 2.2(b) or (b) any
portion of any Earnout Payment that is payable in cash, when due, and such
failure shall continue for a period of five (5) business days following such due
date, such unpaid amount shall bear interest at an annual rate of twelve percent
(12%) from the date of the expiration of such five (5) day grace period until
paid in full by Purchaser.

                  6.4 Operation of Business During Earnout Period. During the
Earnout Period, Purchaser will use commercially reasonable efforts to cause the
business of ICTI to be operated in the ordinary course consistent with the past
practice of ICTI, and neither Purchaser nor its director representatives on the
board of directors of ICTI will intentionally take any affirmative action, or
intentionally omit to take any commercially reasonable action within its
reasonable control, that would directly, materially and adversely affect NIBT
prior to September 30, 2001. If Purchaser takes any such intentional action or
makes any such intentional omission which has a direct, material and adverse
effect on NIBT during the Earnout Periods, Purchaser and Sellers shall proceed
diligently and in good faith, using commercially reasonable efforts, to make
such reasonable adjustments to the calculation of NIBT as may be necessary to
mitigate or neutralize the impact of any such intentional act or omission.
Anything to the contrary set forth in this Section 6.4 notwithstanding,
Purchaser will not be deemed to have violated its obligations under this Section
6.4 if any such intentional act or omission that has a direct, material and
adverse effect on NIBT during the Earnout Periods was (a) directly or indirectly
necessitated by Purchaser's efforts to mitigate or otherwise alleviate the
adverse consequences of a breach of any representation, warranty or covenant of
any Seller under this Agreement or (b) believed by Purchaser or its director
representatives on the board of directors of ICTI, in good faith and in their
business judgment, to have been in, or not opposed to, the best interests of
ICTI or

                                       58
<PAGE>   67
the consolidated group of corporations of which ICTI is then a member.
Furthermore, insofar as ICTI's working capital line of credit facility with the
Secured Lender will be terminated at or prior to the Closing, Purchaser shall,
during the Earnout Periods, use commercially reasonable efforts to ensure that
ICTI has working capital sufficient to undertake and complete projects that are
normally within the scope of ICTI's business and which would affect NIBT.
Nothing set forth in this Section 6.4 or in Section 6.5 shall require, or shall
be deemed to require, Purchaser to make any additional capital contribution to
ICTI.

                  6.5 Operations Through September 30, 1999. Insofar as ICTI's
working capital line of credit facility with the Secured Lender will be
terminated at or prior to the Closing, during the period between the Closing
Date and September 30, 1999, Purchaser will permit ICTI to use its earnings for
such period for usual, customary and legitimate working capital purposes.

                  6.6 Delivery of Certain Minutes. As soon as available, but in
no event later than June 30, 1999, Purchaser will deliver, or cause to be
delivered, to the Seller Representatives copies of the minutes of Galen Holdings
ratifying its execution and delivery of the Guaranty appended hereto, which
minutes will be certified as true and correct by the Secretary of Galen
Holdings.

         7. INDEMNIFICATION; REMEDIES

                  7.1 Survival. Subject to the limitations set forth in Section

                  7.2 General Indemnification and Reimbursement by the Sellers.
In addition to the specific indemnity set forth in Section 7.4 relating to
Taxes, the Sellers will jointly and severally indemnify, defend and hold
harmless Purchaser, its Affiliates (including ICTI) and the respective officers,
directors, shareholders, successors and permitted transferees and assigns of
Purchaser and its Affiliates (collectively, the "Purchaser Indemnitees") from
and against, and will reimburse the Purchaser Indemnitees for, any Damages
arising directly from any of the following:

                                    (a) any Breach of any representation or
         warranty made by any of the Sellers in this Agreement, the Schedules,
         any

                                       59
<PAGE>   68
         supplements to the Schedules, or any other Related Agreements delivered
         by any of the Sellers pursuant to or in connection with this Agreement;

                                    (b) any Breach by any of the Sellers of any
         covenant or obligation of any of the Sellers in this Agreement or any
         Related Agreement; and

                                    (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 Person with
         ICTI or any of the Sellers (or any Person acting on their behalf) in
         connection with any of the Contemplated Transactions.

                  7.3 General Indemnification and Reimbursement by Purchaser.
Purchaser will indemnify, defend and hold harmless the Sellers and the
respective Affiliates, successors and permitted transferees and assigns of the
Sellers (collectively, the "Seller Indemnitees") from and against, and will
reimburse the Seller Indemnitees for, any Damages arising directly from any of
the following:

                                    (a) any Breach of any representation or
         warranty made by Purchaser in this Agreement or in any Related
         Agreement delivered by Purchaser pursuant to or in connection with this
         Agreement;

                                    (b) any Breach by Purchaser of any covenant
         or obligation of Purchaser in this Agreement or any Related Agreement;
         or

                                    (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 such Person
         with Purchaser (or any Person acting on its behalf) in connection with
         any of the Contemplated Transactions.

                  7.4 Tax Indemnification; Apportionment of Taxes.

                                    (a) In addition to the general
         indemnification set forth in Section 7.2, the Sellers will jointly and
         severally indemnify, defend and hold harmless the Purchaser Indemnitees
         and ICTI harmless from any and all Taxes and related Damages imposed on
         ICTI in respect of its income, business, property or operations or for
         which ICTI may otherwise

                                       60
<PAGE>   69
         be liable (i) for any period ending prior to or on the Closing Date,
         including any Short Period or Interim Period and including any Tax
         arising under Section 1374 of the Code, (ii) arising out of a Breach of
         any of the representations and warranties contained in Section 3.8, or
         (iii) for any costs or expenses incurred by Purchaser or ICTI with
         respect to any Taxes for which Purchaser or ICTI is indemnified by the
         Sellers pursuant to this Section 7.4(a).

                                    (b) In order to appropriately apportion any
         Taxes relating to any taxable period that includes the Closing Date,
         the parties hereto will, to the extent permitted by applicable law,
         elect with the relevant taxing authority to treat for all purposes the
         Closing Date as the last day of a taxable period of ICTI (a "Short
         Period"), and such period shall be treated as a Short Period and a
         period ending prior to or on the Closing Date for purposes of this
         Agreement. In any case where applicable Legal Requirements do not
         permit ICTI to treat the Closing Date as the last day of a Short
         Period, then for purposes of this Agreement, the portion of each Tax
         that is attributable to the operations of ICTI for such interim period
         (the "Interim Period") shall be (i) in the case of a Tax that is not
         based on net income, the total amount of such Tax for the period in
         question multiplied by a fraction, the numerator of which is the number
         of days in the Interim Period, and the denominator of which is the
         total number of days in such period, and (ii) in the case of a Tax that
         is based on net income, the Tax that would be due with respect to the
         Interim Period if such Interim Period were a Short Period determined
         based upon an interim closing of the books of ICTI.

                  7.5 Time Limitations.

                                    (a) Except as otherwise specifically
         provided in Sections 7.5(b) and 7.5(c), the Sellers will have no
         Liability to the Purchaser Indemnitees under, or in connection with,
         this Agreement or any of the Related Agreements or any of the
         Contemplated Transactions pursuant to Section 7.2(a), unless on or
         before September 30, 2001, the Seller Representatives are given written
         notice from a Purchaser Indemnitee of a bona fide indemnity claim
         specifying the factual basis of that claim in reasonable detail (a
         "Claim Notice"); provided, however, that with respect to any such claim
         for which a Claim Notice has been given to the Seller Representatives
         on or before September 30, 2001, the Sellers' Liability to the

                                       61
<PAGE>   70
         Purchaser Indemnitees for such claim shall survive without limitation
         as to time until such claim is resolved.

                                    (b) Notwithstanding the provisions of
         Section 7.5(a), the Sellers will have no Liability to the Purchaser
         Indemnitees under, or in connection with, any claims made pursuant to
         Section 7.4, unless before the end of the thirty (30) day period
         immediately following the expiration of the applicable tax statute of
         limitations, the Seller Representatives are given a Claim Notice for a
         claim arising under Section 7.4 (a "Tax Claim"); provided, however,
         that with respect to any such Tax Claim for which a Claim Notice has
         been given to the Seller Representatives prior to the end of the thirty
         (30) day period immediately following the expiration of the applicable
         tax statute of limitations, the Sellers' Liability to the Purchaser
         Indemnitees for such Tax Claim shall survive without limitation as to
         time until such claim is resolved. The term "applicable tax statute of
         limitations," as used in this Section 7.5(b), means, with respect to
         any particular type of Tax, a period of time equal to the applicable
         statute of limitations established pursuant to any Legal Requirement
         pertaining to such Tax.

                                    (c) Notwithstanding the provisions of
         Section 7.5(a), the limitations set forth in Section 7.5(a) shall not
         apply to any claims which are made by any Purchaser Indemnitee pursuant
         to Section 7.2(a) to the extent that such claims are (i) based upon a
         Breach of any of the representations or warranties set forth in
         Sections 3.2, 3.6(a)(i), 3.18(b)(i), 3.18(b)(v) or 3.18(c) or (ii)
         attributable to the fraud of any of the Sellers.

                  7.6 Limitations on Amount of Liability.

                                    (a) Except as otherwise provided in Section
         7.6(c), the Sellers will have no Liability to the Purchaser
         Indemnitees, under, or in connection with, this Agreement or any of the
         Related Agreements or any of the Contemplated Transactions pursuant to
         indemnity claims made pursuant to Section 7.2(a), until the total of
         all Damages with respect to such claims exceeds Eighty Thousand Dollars
         ($80,000.00) (the "Deductible"), and then only for the amount by which
         such Damages exceed the Deductible.

                                       62
<PAGE>   71
                                    (b) Except as otherwise provided in Section
         7.6(c), the maximum amount of Damages that the Sellers shall, in the
         aggregate, be required to pay to the Purchaser Indemnitees pursuant to
         Section 7.2(a) shall be an amount equal to (i) Four Million Dollars
         ($4,000,000.00) plus (ii) the Earnout Payments.

                                    (c) Notwithstanding the provisions of
         Sections 7.6(a) and 7.6(b), (i) Sections 7.6(a) and 7.6(b) shall not
         apply with regard to any Tax Claims or any claim attributable to the
         fraud of any of the Sellers, (ii) Section 7.6(a) shall not apply to any
         claims which are made by any Purchaser Indemnitee pursuant to Section
         7.2(a) to the extent that such claims are based upon a Breach of any of
         the representations or warranties set forth in Section 3.2, and (iii)
         Section 7.6(b) shall not apply to any claims which are made by any
         Purchaser Indemnitee pursuant to Section 7.2(a) to the extent that such
         claims are based upon a Breach of any of the representations or
         warranties set forth in Sections 3.2, 3.6(a)(i), 3.18(b)(i), 3.18(b)(v)
         or 3.18(c).

                  7.7 Procedure for Indemnification - Third Party Claims.

                                    (a) All claims for indemnification under
         this Agreement shall be governed by the procedures set forth in this
         Section 7.7.

                                    (b) When a party seeking indemnification
         under Sections 7.2, 7.3 or 7.4 (the "Indemnified Party") receives
         notice of any claims made by third parties ("Third Party Claims") or
         has any other claim for indemnification other than a Third Party Claim,
         which is or may be the basis of a claim for indemnification hereunder,
         the Indemnified Party shall promptly deliver a Claim Notice to the
         other party (the "Indemnifying Party"); provided, however, that the
         failure of the Indemnified Party to promptly deliver a Claim Notice as
         provided herein shall not relieve the Indemnifying Party of any of its
         obligations hereunder unless and only to the extent that the
         Indemnifying Party shall have been prejudiced thereby. Upon receipt of
         a Claim Notice from the Indemnified Party with respect to a Third Party
         Claim, the Indemnifying Party may, but shall not be required to, assume
         the defense of such Third Party Claim. Should the Indemnifying Party
         elect to undertake the defense of any Third Party Claim, it shall use
         counsel of its choice but reasonably acceptable to the Indemnified
         Party, and the Indemnifying Party shall pay all reasonable costs and
         expenses thereof

                                       63
<PAGE>   72
         (including the reasonable costs and expenses incurred by the
         Indemnified Party in connection with the defense of such Third Party
         Claim prior to the assumption of such defense by the Indemnifying
         Party) and shall be fully responsible for the outcome thereof;
         provided, however, that in such case, the Indemnifying Party shall have
         no obligation to pay any further costs or expenses of legal counsel of
         the Indemnified Party thereafter incurred in connection with such
         defense. An Indemnifying Party's right to assume the defense of any
         Third Party Claim is conditioned upon (i) the Indemnifying Party
         acknowledging in writing to the Indemnified Party, without
         qualification or limitation, its obligation to indemnify the
         Indemnified Party for all Damages arising from such Third Party Claim
         and (ii) the Indemnifying Party providing the Indemnified Party with
         security or other satisfactory assurances that it has the financial
         ability to fully indemnify the Indemnified Party for such Damages. No
         compromise or settlement in respect of any Third Party Claims may be
         effected by the Indemnifying Party without the Indemnified Party's
         prior written consent (which consent shall not be unreasonably withheld
         or delayed). The Indemnifying Party shall give notice to the
         Indemnified Party as to its intention to assume the defense of any
         Third Party Claims within ten (10) days after the date of receipt of
         the Indemnified Party's Claim Notice in respect of such Third Party
         Claims. If an Indemnifying Party does not, within ten (10) days after
         the Indemnified Party's Claim Notice is given, give notice to the
         Indemnified Party of its assumption of the defense of the Third Party
         Claims, the Indemnifying Party shall be deemed to have waived its right
         to control the defense thereof. If the Indemnified Party assumes the
         defense of any Third Party Claims because of the failure of the
         Indemnifying Party to do so in accordance with this Section 7.7(b), it
         may do so in such manner as it may deem appropriate, and the
         Indemnifying Party shall pay all costs and expenses of such defense.
         The Indemnifying Party shall have no liability with respect to any
         compromise or settlement of a Third Party Claim that is effected
         without its prior written consent (which consent shall not be
         unreasonably withheld or delayed).

                                    (c) Notwithstanding the provisions of
         Section 7.7(b), with respect to any Third Party Claim that the
         Indemnifying Party is defending, the Indemnified Party shall have the
         right to retain separate counsel to represent it and the Indemnifying
         Party shall pay the reasonable fees and expenses of such separate
         counsel, but only if, and to the

                                       64
<PAGE>   73
         extent that (ii) the Indemnifying Party shall not have engaged counsel
         reasonably satisfactory to the Indemnified Party to represent the
         Indemnified Party within a reasonable amount of time after the
         Indemnified Party's Claim Notice is given or (iii) the Indemnifying
         Party shall authorize, in writing, the Indemnified Party to engage
         separate counsel at the Indemnifying Party's expense.

                                    (d) If the Indemnified Party desires to
         settle any Third Party Claim (whether or not contested by the
         Indemnifying Party), the Indemnified Party shall advise the
         Indemnifying Party in writing of the amount it proposes to pay in
         settlement thereof. If such proposed settlement is unsatisfactory to
         the Indemnifying Party, it shall have the right, at its expense,
         reasonably to contest (or continue to contest) such Third Party Claim
         by giving written notice of such election to the Indemnified Party
         within fifteen (15) days after the Indemnifying Party's receipt of the
         advice of the proposed settlement. If the Indemnifying Party does not
         deliver such written notice within fifteen (15) days after receipt of
         such advice, or if the Indemnifying Party, after having given such
         notice to the Indemnified Party, fails to defend, settle or pay such
         Third Party Claim, the Indemnified Party may offer the proposed
         settlement to the third party making such Third Party Claim. If the
         proposed settlement is not accepted by the party making such Third
         Party Claim, any new proposed settlement figure which the Indemnified
         Party may wish to present to the party making such Third Party Claim
         shall first be presented to the Indemnifying Party who shall have the
         right, subject to the conditions set forth in this Section 7.7(d),
         reasonably to contest such Third Party Claim. In all such events, the
         Indemnifying Party shall indemnify the Indemnified Party and hold it
         harmless against and from any and all costs of defense, payment or
         settlement, including reasonable attorneys' fees incurred in connection
         therewith.

                                    (e) The Indemnifying Party may settle any
         Third Party Claim only if it has agreed to contest the claim in
         accordance with Section 7.7(b) above. If any Indemnifying Party desires
         to settle any Third Party Claim, the Indemnifying Party shall not,
         without the Indemnified Party's prior written consent (which consent
         shall not be unreasonably withheld, delayed or conditioned), (i) settle
         or compromise such proceeding, claim or demand, or consent to the entry
         of any judgment which does not include as an unconditional term thereof
         the delivery by the

                                       65
<PAGE>   74
         claimant or plaintiff to the Indemnified Party of a written release
         from all liability in respect of such proceeding, claim or demand or
         (ii) settle or compromise any such proceeding, claim or demand, in any
         manner that would be reasonably likely to adversely affect the
         Indemnified Party other than as a result of money damages or other
         money payments which are fully indemnified against by the Indemnifying
         Party.

                                    (f) Notwithstanding the foregoing, if an
         Indemnified Party determines in good faith that there is a reasonable
         probability that a Third Party Claim may adversely affect it or any of
         its Related Persons other than as a result of monetary damages for
         which it would be entitled to indemnification under this Agreement, or
         if an Indemnified Party reasonably believes that it may not receive the
         indemnification to which it may be entitled from the Indemnifying
         Party, the Indemnified Party may, by notice to the Indemnifying Party,
         assume the exclusive right to defend, compromise or settle such Third
         Party Claim, but the Indemnifying Party will not be bound by any
         compromise or settlement of a Third Party Claim so defended if such
         compromise or settlement is effected without its consent (which consent
         may not be unreasonably withheld or delayed).

                  7.8 Exclusive Remedy; Etc.

                                    (a) Except as specifically set forth in
         Section 7.8(c), the sole and exclusive remedy of Purchaser and the
         Sellers for any all claims or Damages relating to or arising out of or
         in connection with this Agreement or any of the Related Agreements or
         Contemplated Transactions and the facts and circumstances relating and
         pertaining thereto (whether any such claim may be made in contract,
         breach of warranty, tort or otherwise) shall be an action for indemnity
         pursuant to this Section 7, which shall be governed and limited by this
         Section 7.

                                    (b) Notwithstanding the provisions of
         Section 7.8(a), each party shall be entitled to pursue those equitable
         or other remedies that may otherwise be available to it pursuant to the
         provisions of the Agreements Not to Compete, the Employment Agreements
         or the Confidentiality and Noncompete Agreements.

                                       66
<PAGE>   75
                  7.9 Set-Off. Purchaser will have the right to set off against
and reduce any sums that may be payable by it to any of the Sellers from time to
time pursuant to this Agreement (including the Three Million Dollar
($3,000,000.00) deferred payment due pursuant to Section 2.2(b) and any of the
Earnout Payments) for any claims that it may have from time to time against any
of the Sellers, whether pursuant to this Section 7 or otherwise.

                  7.10 Form of Indemnification Payments. Except to the extent
the Damages for claims of Purchaser against the Sellers under this Section 7
exceed Three Million Dollars ($3,000,000.00), the Purchaser Indemnitees shall
have the right to seek indemnification from the Sellers for claims against the
Sellers under this Section 7 only by setting-off against the Three Million
Dollar ($3,000,000.00) deferred payment payable pursuant to Section 2.2(b).
However, with regard to claims for Damages with respect to which a Purchaser
Indemnitee gives a Claim Notice after Purchaser's payment of the Three Million
Dollar ($3,000,000.00) deferred payment described in Section 2.2(b) or to the
extent that the aggregate amount of Damages for claims against the Sellers
pursuant to this Section 7 exceeds Three Million Dollars ($3,000,000.00), the
Purchaser Indemnitees may elect to proceed against the Sellers for such excess
(rather than, but not in lieu of, setting-off against any Earnout Payments that
may be payable to Sellers hereunder), provided however, that with respect to any

Agreement, nor will this Section 7.12 alter, affect or limit any rights or
remedies that any of the Purchaser Indemnitees may have against any of the
Sellers for their Breach of any of their respective obligations under any
Related Agreement (including the Agreements Not to Compete and the
Confidentiality and Noncompete Agreements).

         8. GENERAL PROVISIONS

                  8.1 Seller Representatives; Power of Attorney. Each of the
Sellers hereby irrevocably makes, constitutes, and appoints Daniel J. Scanlon
and Scott C. McCarty as the Seller Representatives and irrevocably authorizes
and empowers the Seller Representatives to receive all demands and notices on or
with respect to the Sellers hereunder as such Sellers' true and lawful
attorneys-in-fact and agents, and for such Seller and in such Seller's name, to
(a) endorse for assignment and transfer to Purchaser the stock certificates
representing the Purchased Shares owned by such Seller for purposes of
facilitating compliance with the provisions of Section 2.3(a)(i), (b) receive
all demands, notices or other communications directed to such Seller under this
Agreement and to take any action (or to determine to refrain from taking any
action) with respect thereto as they may deem appropriate as effectively as such
Seller could act for himself or herself (including, without limitation, the
settlement or compromise of any dispute or controversy) and (c) execute and
deliver all instruments and documents of every kind incident to the foregoing
with the same effect as if such Seller had executed

                                       68
<PAGE>   77
and delivered such instruments and documents personally. Accordingly, any
demands, notices or other communications directed to the Sellers hereunder shall
be deemed effective if given to the Seller Representatives. Upon the death,
resignation or incapacity of either of the Seller Representatives, a successor
shall be appointed by the remaining Sellers within the thirty (30) day period
immediately following the date of such death, resignation or incapacity, and
such successor shall either be a Seller or any other Person reasonably
acceptable to Purchaser who shall agree in writing to accept such appointment in
accordance with the terms hereof. The resignation of any Seller Representative
shall not be effective until a successor Seller Representative has been
appointed, and has accepted such appointment in accordance with the provisions
of this Section 8.1. The selection of a successor Seller Representative
appointed in any manner permitted in this Section 8.1 shall be final and binding
upon all of the Sellers and written notice of such selection and appointment
shall be provided to Purchaser promptly.

                  8.2 Expenses. Except as otherwise expressly provided in this
Agreement, each party to this Agreement will bear its respective expenses
incurred in connection with (a) the preparation, negotiation, execution, and
performance of this Agreement and (b) any of the Contemplated Transactions,
including all fees and expenses of agents, Representatives, counsel, and
accountants and in no event shall any such costs of the Sellers be paid,
directly or indirectly, by ICTI.

                  8.3 Public Announcements. Any public announcement or similar
publicity with respect to this Agreement, the Contemplated Transactions or any
of the terms thereof will be issued, if at all, at such time, in such manner and
shall include only such information as Purchaser and the Sellers shall mutually
agree upon in writing. Unless consented to by the other party in advance in
writing or required by Legal Requirements, Purchaser and the Sellers shall keep
this Agreement strictly confidential and neither Purchaser nor the Sellers will
make, or cause to be made, any disclosure of this Agreement or any of its terms
to any Person. Anything to the contrary set forth in this Section 8.3
notwithstanding, in no event shall any party be permitted to announce publicly
the Purchase Price without the prior written consent of the other parties unless
required by applicable Legal Requirements.

                  8.4 Notices. All notices, consents, waivers, and other
communications under this Agreement must be in writing and will be deemed to

<PAGE>   79
Philadelphia, Pennsylvania. Each party hereby irrevocably consents and submits
to the jurisdiction and venue of such courts and irrevocably waives any
objection which it may now or hereafter have to the laying of the venue of any
suit, action or Proceeding brought in such courts and any claim that such suit,
action or Proceeding brought in such courts has been brought in an inconvenient
forum or that such courts lack jurisdiction.

                  8.6 Further Assurances. The parties agree (a) to furnish upon
request to each other such further information, (b) to execute and deliver to
each other such other documents, and (c) to do such other acts and things, all
as the other party may reasonably request for the purpose of carrying out the
intent of this Agreement and the Related Agreements and the documents referred
to in this Agreement and the Related Agreements.

                  8.7 Waiver. The rights and remedies of the parties to this
Agreement 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.

                  8.8 Entire Agreement and Modification. This Agreement
supersedes all prior agreements between the parties with respect to its subject
matter and constitutes (along with the Related Agreements) a complete and
exclusive statement of the terms of the agreement between the parties with
respect to its and their subject matter. This Agreement may not be amended
except by a written agreement executed by the party to be charged with the
amendment.

                  8.9 Assignments, Successors, and No Third-Party Rights. None
of the parties may assign or otherwise transfer any of their respective rights
under this Agreement without the prior consent of the other parties; provided,
however, that Purchaser, without the consent of the Sellers, shall be permitted
to pledge and assign any or all of Purchaser's rights hereunder to any of its
Affiliates or to any financial institutions now or hereafter providing financing
to Purchaser or to Galen Holdings or to the consolidated group of corporations
of which they are a member as collateral security for their obligations to such
institutions. Any attempted assignment in contravention of the foregoing
restrictions on assignment or transfer shall be null and void. Subject to the
two preceding sentences, this

                                       71
<PAGE>   80
Agreement will apply to, be binding in all respects upon, and inure to the
benefit of the successors, permitted assigns, heirs, executors, and personal
representatives of the parties. Except as provided in this Section 8.9, nothing
expressed or referred to in this Agreement will be construed to give any Person
other than the parties to this Agreement any legal or 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, permitted assigns, heirs, executors, and personal representatives.

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

                  8.11 Section Headings, Construction. The headings of Sections
in this Agreement are provided for convenience only and will not affect its
construction or interpretation.

                  8.12 Time of Essence. With regard to all dates and time
periods set forth or referred to in this Agreement, time is of the essence.

                  8.13 Governing Law. This Agreement will be governed by and
construed under the laws of the Commonwealth of Pennsylvania without regard to
its principles pertaining to conflict of laws.

                  8.14 Counterparts. This Agreement may be executed in two or
more counterparts, each of which will be deemed to be an original of this
Agreement and all of which, when taken together, will be deemed to constitute
one and the same agreement. Any party to this Agreement, as well as Galen
Holdings who is a party to the Guaranty appended hereto, may deliver an executed
copy hereof, the Guaranty and of any of the Related Agreements by facsimile
transmission to another party hereto or thereto and any such delivery shall have
the same force and effect as any other delivery of a manually signed copy of
this Agreement, the Guaranty or of any other Related Agreement.

                  8.15 Records Retention. For a period of seven (7) years after
the Closing Date, Purchaser shall afford to the Seller Representatives

R. Boissonneault Series C No. W03
Execution Copy

     SUPPLEMENTAL AGREEMENT NO. 1 TO WARNER CHILCOTT PUBLIC LIMITED COMPANY
                               WARRANT CERTIFICATE

            WHEREAS, ROGER BOISSONNEAULT (the "Warrant Holder") is the holder of
certain warrants (the "Warrants") of Warner Chilcott Public Limited Company
("WC") as set forth in a certificate numbered SERIES C NO. W03 (the "Warrant
Certificate");

            WHEREAS, on September 29, 2000 WC and Galen Holdings PLC ("Galen"),
consummated a change of control transaction (the "Acquisition") by means of a
scheme of arrangement under the laws of the Republic of Ireland (the "Scheme")
whereby Galen exchanged all of the outstanding securities of WC for ordinary
shares in Galen; and

            WHEREAS, unless otherwise defined herein, capitalized terms used
herein will have the meanings set forth in the Warrant Certificate.

            NOW THEREFORE, the parties agree as follows:

            1. Change in Number and Purchase Price of Warrants. Under the
Scheme, holders of warrants to purchase WC's American Depository Receipts
("ADR's"), evidencing WC's American Depository Shares ("ADS's") will, upon
exercise, receive ordinary shares of Warner Chilcott, each of which will
immediately be exchanged pursuant to the Scheme for 2.5 ordinary shares of
Galen, to be held in the form of Galen ADR's evidencing Galen ADS's. Each Galen
ADS currently represents four Galen ordinary shares. As a result, (a) each
holder of warrants to purchase WC ADR's will, upon such exercise and immediate
exchange, receive 0.625 Galen ADR's for each WC ADR, with fractions of ADR's
being rounded as appropriate, and (b) the effective purchase price for these
Galen ADR's shall be derived by dividing the Purchase Price of WC ADR's by
0.625. Therefore, the Warrant Certificate will hereinafter have the effect of
entitling the Warrant Holder to purchase 75,000 Galen ADR's at a purchase price
of $32.00.

            2. Net Exercise. The following language shall be added to the end of
Section 2(e) of the Warrant Certificate:

            "IN LIEU OF PAYMENT OF THE PURCHASE PRICE AS SET FORTH IN THE FIRST
            SENTENCE OF THIS SECTION 2(e), THE WARRANT HOLDER MAY EXERCISE THIS
            WARRANT BY DELIVERING A NOTICE OF NET EXERCISE IN THE FORM OF
            EXHIBIT A HERETO ELECTING TO RECEIVE, WITHOUT CASH PAYMENT BY THE
            WARRANT HOLDER OF ANY ADDITIONAL CONSIDERATION, ORDINARY SHARES THAT
            WILL IMMEDIATELY BE EXCHANGED FOR GALEN ADR'S EQUAL TO THE VALUE OF
            THE WARRANTS (OR THE PORTION THEREOF BEING CANCELED) BY SURRENDER OF
            THIS WARRANT CERTIFICATE TOGETHER WITH THE FORM OF NET EXERCISE
            (ATTACHED HERETO AS EXHIBIT A) DULY EXECUTED, IN WHICH EVENT THE
            COMPANY SHALL ISSUE TO THE WARRANT HOLDER HEREOF (UPON THE IMMEDIATE
            EXCHANGE OF
<PAGE>   2
R. Boissonneault Series C No. W03
Execution Copy

            ORDINARY SHARES PURSUANT TO THE SCHEME) A NUMBER GALEN ADR'S
            COMPUTED USING THE FOLLOWING FORMULA:

                                   X= Y (A-B)
                                     ---------
                                         A

            WHERE:      X=THE NUMBER OF GALEN ADR'S TO BE ISSUED TO THE WARRANT
                        HOLDER PURSUANT TO THIS NET EXERCISE;

                        Y= THE NUMBER OF GALEN ADR'S IN RESPECT OF WHICH THE NET
                        ISSUE ELECTION IS MADE;

                        A= THE FAIR MARKET VALUE OF ONE GALEN ADR AT THE TIME
                        THE NET ISSUE ELECTION IS MADE; AND

                        B= THE PURCHASE PRICE (AS ADJUSTED TO THE DATE OF THE
                        NET ISSUANCE) DIVIDED BY 0.625.

            FOR PURPOSES OF THIS SECTION 2(e), THE FAIR MARKET VALUE OF ONE
            GALEN ADR AS OF A PARTICULAR DATE SHALL BE DETERMINED BY USING THE
            AVERAGE OF THE CLOSING PRICES OF THE GALEN ADR'S TRADED ON THE
            NASDAQ NATIONAL MARKET (OR ANY SUCCESSOR UNITED STATES NATIONAL
            MARKET THE GALEN ADR'S TRADE ON) OVER THE TWENTY (20) DAY PERIOD
            ENDING THREE (3) DAYS PRIOR TO THE NET EXERCISE ELECTION."

            3. Deposit Agreement. The reference to "Deposit Agreement" in
Section 3 of the Warrant Certificate shall be amended so that it refers instead
to the Amended and Restated Deposit Agreement among WC, Galen and The Bank of
New York as Depositary, dated September 29, 2000.
