all of the issued and outstanding shares of capital stock of the Company.



     1.2 Consideration. As consideration for the contribution, exchange,

the basis of the September 30 Balance Sheet, and (ii) $300,000 (the "Escrow
Amount") to be held in escrow by Parker Chapin Flattau & Klimpl, LLP, as escrow

(the Cash Portion of the Consideration as so adjusted, the "Cash
Consideration"), and (b) an aggregate of 6,000 shares of MedSource's Series A

section 1.4(b)), if any, and (ii) the Preferred Stock.

          (2) At the Closing, the Transferee shall deliver to the Escrow Agent
an amount equal to the Escrow Amount.

          (3) Upon the determination of the Cash Consideration, as finally
determined in accordance with section 1.4(d) on the basis of the Closing Date

Transferee shall cause the Escrow Agent to pay to the Transferors the Escrow
Amount in accordance with the Escrow Agreement or, alternatively, (ii) the
Transferors shall pay to the Transferee the amount of the Final Cash
Consideration Decrease (as defined in section 1.4(d)) (each such payment, a
"Cash Consideration Adjustment"), if any, which such Final Cash Consideration
Decrease shall be made from the Escrow Amount in accordance with the terms of
the Escrow Agreement (and the Transferee shall cause the Escrow Agent to pay to
the Transferors the portion of the Escrow Amount that exceeds the amount of such
Final Cash Consideration Decrease, if any, in accordance with the Escrow
Agreement) and, if such Final Cash Consideration Decrease exceeds the Escrow
Amount, then such excess shall be paid by the Transferors pursuant to section
1.4(f) hereof.

                                      -2-



          (4) In the event that the Company (i) purchases any equipment,
Intellectual Property (as defined in section 3.11) or other assets from any
Transferror or any Affiliate (as defined in section 3.15) of any Transferor
pursuant to section 5.18 or (ii) makes any payments to any Transferor or any
Affiliate of any Transferor pursuant to section 5.19(a), then in each case the
Fixed Cash Amount delivered to the Transferors shall be reduced by an amount
equal to the amount paid to such Transferor or such Affiliate (pursuant to
section 5.18 or 5.19(a), as the case may be), if any; provided, however, that
                                                      --------  ------
the amount of any such reduction pursuant to the foregoing shall be deemed to
have been paid by the Transferee to the Transferors.

     1.4 Cash Consideration Adjustments.
          -----------------------------

          (1) At least three business days prior to the Closing Date, the
Transferors shall deliver to the Transferee (i) a balance sheet (the "Estimated
Closing Date Balance Sheet") based upon the books and records of the Company and
prepared in accordance with generally accepted accounting principles,
consistently applied, as of the date of this Agreement ("GAAP") (except as to
the operating lease treatment of the East Longmeadow real estate rental) and
reflecting the Company's best estimate of each of the items, and the amounts
thereof, to be included on the Closing Date Balance Sheet and (ii) a certificate
of Laurence S. Derose, duly executed by such Transferor, stating that the
Estimated Closing Date Balance Sheet has been prepared in good faith, has been
prepared in accordance with GAAP (except as to the operating lease treatment of
the East Longmeadow real estate rental) and reflects the Transferors' best
estimate of, and fairly presents, each of the items, and the amounts thereof, to
be included on the Closing Date Balance Sheet. Notwithstanding anything to the
contrary in the foregoing, accrued liabilities for vacation pay, Christmas
bonuses and "shutdown expenses" shall be accounted for on a basis consistent
with the accounting for such items on the September 30 Balance Sheet.

          (2) If the Net Asset Amount of the Company as shown on the Estimated
Closing Date Balance Sheet is greater than the Net Asset Amount shown on the
September 30 Balance Sheet, the payment of the Fixed Cash Amount to the
Transferors on the Closing Date shall be increased, as a preliminary adjustment
to the Fixed Cash Amount as provided in section 1.3(a)(i), by the amount of such
excess (the "Estimated Price Increase"). If the Net Asset Amount of the Company
as shown on the Estimated Closing Date Balance Sheet is less than the Net Asset
Amount as shown on the September 30 Balance Sheet, the payment of the Fixed Cash
Amount to the Transferors on the Closing Date shall be decreased, as a
preliminary adjustment to the Fixed Cash Amount as provided in section
1.3(a)(i), by the amount of such deficiency (the "Estimated Price Decrease").
For purposes of this Agreement, "Net Asset Amount" of the Company as of any date
shall mean the total assets of the Company less the sum of (i) cash and
equivalents, (ii) all "accounts payable" of the Company, (iii) all "accrued
payroll" of the Company, (iv) all "accrued liabilities" of the Company
(excluding, all accrued income taxes payable and accrued bonuses payable to
affiliates), and (v) all Institutional Indebtedness (as defined below) of the
Company; provided, however, that "Net Asset Amount" on the Estimated Closing
         --------  -------
Date Balance Sheet and on the Closing Date Balance Sheet in each case shall
exclude any and all assets transferred to the Company by any of the Transferors,
by their respective

                                      -3-



Affiliates or by any other Person (as defined in section 3.4(c)) affiliated with
any of them pursuant to section 5.18 or otherwise. For the purposes of this
Agreement, "Institutional Indebtedness" shall mean all current and long-term
obligations of the Transferor under revolving credit facilities, term loans and
notes and lines of credit or loans due to banks or similar financial
institutions, negative book balances and overdrafts and capital lease
obligations and shall not include obligations to any Transferor or Affiliate
thereof.

          (3) As of the close of business on the last day of the fiscal month of
the Company in which the Closing occurs, or at such other time on such other
date as near as practicable thereto as may be mutually agreed to by the parties
to avoid business disruptions, the Transferee shall cause physical counts to be
made of the inventory of the Company located at such of the Company's facilities
as the Transferee shall request (the "Inventory Count"), which shall be observed
by the accounting firm of Ernst & Young LLP, the costs of the physical inventory
to be paid by the Transferee. The Transferors' representatives shall be entitled
to attend and observe the taking of the Inventory Count. Upon completion of the
Inventory Count (and any adjustment pursuant to the immediately following
sentence), the Transferors shall be provided with copies of the relevant data
relating to those counts for its review. The results of the Inventory Count
shall be adjusted to reflect the Company's inventory at the close of business on
the day immediately preceding the Closing Date using actual receipts and
shipments, and the valuation of inventory for purposes of the Closing Date
Balance Sheet shall be based on the results of the Inventory Count as so
adjusted.

          (4) Within 45 days following the Closing Date, the Transferors shall
deliver to the Transferee a special purpose balance sheet of the Company as of
immediately prior to the Closing prepared by the Transferors with the assistance
of the Transferee (the "Closing Date Balance Sheet"). The Closing Date Balance
Sheet shall be prepared in accordance with GAAP (except as to the operating
lease treatment of the East Longmeadow real estate rental) and shall set forth
the calculation of the Net Asset Amount in a manner consistent with the
calculation thereof on the September 30 Balance Sheet and the Estimated Closing
Date Balance Sheet as of the Closing Date. If the Net Asset Amount of the
Company as reflected in the Closing Date Balance Sheet is greater than the Net
Asset Amount of the Company reflected in the Estimated Closing Date Balance
Sheet, the Estimated Cash Consideration shall be increased, by a final
adjustment to the Estimated Cash Consideration as provided in section 1.3(c)(i),
by the amount of such excess (the "Final Cash Consideration Increase"). If the
Net Asset Amount of the Company as reflected in the Closing Date Balance Sheet
is less than the Net Asset Amount as reflected in the Estimated Closing Date
Balance Sheet, the Estimated Cash Consideration shall be decreased, by a final
adjustment to the Estimated Cash Consideration as provided in section
1.3(c)(ii), by the amount of such deficiency (the "Final Cash Consideration
Decrease"). Any increase or decrease in the Estimated Cash Consideration
pursuant to this section 1.4(d) shall be paid pursuant to section 1.4(f)
promptly after delivery of the Closing Date Balance Sheet or, if there is a
Dispute (as defined in section 1.4(e)), promptly after resolution of such
Dispute.

                                      -4-



          (5) The Transferee shall have 30 days after receipt by it of the
Closing Date Balance Sheet (the "Dispute Period") to dispute any item,
calculation or amount, or the method of calculation of any item or amount,
reflected therein (a "Dispute"). If the Transferee does not give written notice
of a Dispute (a "Dispute Notice") to the Transferors within the Dispute Period,
the Closing Date Balance Sheet shall be deemed to have been accepted by the
Transferee in the form in which it was delivered by the Company. In the event
that the Transferee does not agree with any item, calculation or amount, or the
method of calculation of any item or amount, reflected on the Closing Date
Balance Sheet, the Transferee shall give the Transferors a Dispute Notice within
the Dispute Period, setting forth the basis of its disagreement, and the
Transferors and the Transferee shall, within 15 days after the receipt by the
Transferors of such Dispute Notice, attempt to resolve such Dispute and agree in
writing upon the final Closing Date Balance Sheet. In the event that the
Transferors and the Transferee are unable to resolve any such Dispute within the
15 day resolution period, then the New Haven office of the certified public
accounting firm of McGladrey & Pullen, LLP or such office of a certified public
accounting firm or office as may be mutually agreed upon by the holders of a
majority of the Shares and the Transferee (the "Arbitrator") shall be employed
as arbitrator hereunder to settle such Dispute as soon as reasonably
practicable, and the parties hereto shall use their reasonable best efforts to
ensure that the Arbitrator decides such matter within 30 days after submission
to such Arbitrator. The parties agree that the Arbitrator shall decide only the
matter involved in the Dispute, and not any other matters. Any Arbitration
pursuant to this section 1.4(e) shall be conducted in the New Haven office of
the Arbitrator, in accordance with the Commercial Arbitration Rules of the
American Arbitration Association then existing and the Arbitrator's
determination with respect to any Dispute shall be final and binding on all
parties and not subject to appeal on any ground, and judgment on the arbitration
award may be enforced in any court having jurisdiction over the subject matter
of the controversy. The Transferor and the Transferee shall each pay one-half of
the fees and expenses of the Arbitrator for the services of the Arbitrator in
the arbitration.

          (6) In the event of a Final Cash Consideration Decrease that is less
than or equal to the Escrow Amount, an amount equal to such Cash Consideration
Adjustment shall be paid by the Escrow Agent to the Transferee and an amount
equal to the remainder of the Escrow Amount shall be paid by the Escrow Agent to
the Transferors, in each case pursuant to the terms of the Escrow Agreement. In
the event of a Final Cash Consideration Decrease that exceeds the Escrow Amount,
the amount of such excess, together with interest on such amount at a rate equal
to the rate of interest announced from time to time by Chase Manhattan Bank to
be its prime or reference rate (the "Prime Rate"), from the Closing Date to the
payment date, shall promptly be paid by the Transferors to the Transferee in
immediately available funds by wire transfer to such bank account as may be
designated by the Transferee. In the event of a Final Cash Consideration
Increase that exceeds the Escrow Amount, the amount of such excess, together
with interest on such amount at the Prime Rate, from the Closing Date to the
payment date, shall promptly be paid by the Transferee to the Transferors in
immediately available funds by wire transfer to such bank account as may be
designated in writing by the Transferors. Payments pursuant to this section
1.4(f) shall be made within 10 days after the final determination of the Closing
Date Balance Sheet.

                                      -5-



2. Closing. The closing (the "Closing") of the transactions contemplated by this
   -------
Agreement shall take place at the offices of the Transferee's counsel in New
York City, at 10:00 a.m. local time (i) on or before April 15, 1999, (ii) or at
such other date and time on which all the conditions set forth in section 6 of
this Agreement are satisfied or (iii) on such date and time on or before April
15, 1999 on which the Transferee informs the Transferors in writing (not less
than seven days prior to such date) that such Closing shall take place (the
"Closing Date").

conducted. The Company is duly qualified or licensed to do business as a foreign
corporation and is in good standing in each jurisdiction in which the nature of
the business conducted by it makes such qualification or licensing necessary and
in which the failure to be so qualified or licensed would have a material
adverse effect on the condition (financial or other), business, assets, results

Transferee true, correct and complete copies of the Company's certificate of
incorporation and bylaws, as currently in effect.

Shares are the only shares of capital stock of the Company that are issued and
outstanding, and all of the Shares are owned of record and beneficially by the

Company.

other similar laws affecting the enforcement of creditors' rights generally.

     3.4 No Violations; Consents and Approvals; Licenses.
         -----------------------------------------------

          (1) Except as set forth on Schedule 3.4, the execution, delivery and

each of the Transferors party thereto do not, and the consummation by each of
the Transferors of the transactions contemplated hereby and thereby will not,
(i) violate any provision of the certificate of incorporation or bylaws of the
Company, (ii) result in a violation or breach of, or constitute (with or without
due notice or lapse of time or both) a default (or give rise to any right of

Transferor may be bound or otherwise subject or (iii) violate any order, writ,
judgment, injunction, decree, law, statute, rule or regulation applicable to the
Company or any Transferor or any of their respective properties or assets.

neither the FDA nor any similar Governmental Agency has issued any "483 reports"
or similar reports, findings or citations and there are no outstanding matters

respective invoices relating thereto.

     3.8 Litigation; Compliance with Law; Licenses and Permits.
         -----------------------------------------------------

          (1) There is no claim, suit, action or proceeding ("Proceeding")
pending, nor, to the knowledge of each of the Transferors, is there any
investigation or Proceeding threatened, that involves or affects the Company (or
its business), by or before any Governmental Entity, court, arbitration panel or
any other Person.

                                      -9-



          (2) Except as set forth on Schedule 3.8, to the knowledge of each of
the Transferors, the Company has, and on the Closing Date will have, complied

every approval, authorization, waiver, variance, exemption, consent or
ratification by or on behalf of any Person that is not a party to this Agreement
(each, a "Permit") required for it to conduct its business as presently
conducted. All such Licenses and Permits are in full force and effect and
neither the Company nor any Transferor has received notice of any pending
cancellation or suspension of any thereof nor, to the knowledge of each of the
Transferors, is any cancellation or suspension thereof threatened. The
applicability and validity of each such License and Permit will not be adversely
affected by the consummation of the transactions contemplated by this Agreement.

     3.9 Employee Benefit Plans; ERISA.
         -----------------------------

          (1) Schedule 3.9(a) lists each "employee benefit plan" (as defined in
Section 3(3) of ERISA), and all other material employee benefit (including,
without limitation, any non-qualified plans), bonus, deferred compensation,
incentive, stock option (or other equity-based), severance, change-in-control,
medical insurance and fringe benefit plans maintained for the benefit of, or
contributed to by the Company or any trade or business, whether or not
incorporated (an "ERISA Affiliate"), that would be deemed a "single employer"
within the meaning of Section 4001 of the Employee Retirement Income Security
Act of 1974 ("ERISA"), for the benefit of any employee or former employee of the
Company (the "Plans"). The Company has heretofore delivered to the Transferee
true, correct and complete copies of each of the Plans, including all amendments
to date.

          (2) With respect to each Plan: (i) such Plan has been administered in
accordance with its terms and applicable law; (ii) no event has occurred and
there exists no circumstance under which the Company could, directly or
indirectly, incur liability under ERISA, the Code or otherwise (other than
routine claims for benefits); (iii) there are no actions, suits or claims
pending (other than routine claims for benefits) or, to the knowledge of the
Company, threatened, with respect to any Plan or against the assets of any Plan;
(iv) all

                                      -10-



contributions and premiums due have been made on a timely basis; and (v) all
contributions made or required to be made under any Plan meet the requirements
for deductibility under the Code, and all contributions which have not been made
have been properly recorded on the books and records of the Company. Each of the
Plans that is subject to ERISA complies with ERISA and the applicable provisions
of the Code and has been administered in accordance with ERISA and, where
applicable, the Code. Each of the Plans intended to be "qualified" within the
meaning of Section 401(a) of the Code has received a timely determination letter
from the Internal Revenue Service that it is so qualified and no Transferor
knows of any facts or circumstances that would materially adversely affect such
qualification prior to and including the close of business on the day
immediately preceding the Closing Date. Except as set forth in Schedule 3.9(b),
none of the Plans is subject to Title IV of ERISA. No "reportable event", as
such term is defined in Section 4043(b) of ERISA (for which the 30-day notice
requirement to the Pension Benefit Guaranty Board ("PBGC") has not been waived),
has occurred with respect to any Plan. There are no pending or, to the best
knowledge of each of the Company and the Transferors, threatened claims (other
than routine claims for benefits), actions, suits or proceedings by, on behalf
of or against any of the Plans or any trusts related thereto.

          (3) No Plan provides benefits including, without limitation, death or
medical benefits (whether or not insured), with respect to any employees or
former employees of the Company beyond their retirement or other termination of
service (other than (i) coverage mandated by applicable law, (ii) death benefits
or retirement benefits under any "employee pension plan," as that term is
defined in Section 3(2) of ERISA, or (iii) benefits the full cost of which is
borne by the current or former employee (or his or her beneficiary)).

          (4) With respect to each Plan, neither the Company, any Transferor nor
any ERISA Affiliate has engaged in a "prohibited transaction" (as such term is
defined in Section 4975 or Section 406 of ERISA) that would subject the Company
or the Transferee to any taxes, penalties or other liabilities resulting from
prohibited transactions under Section 4975 of the Internal Revenue Code of 1986,
as amended, and the Treasury Regulations thereunder (the "Code") or Section 409
or 502(i) of ERISA.

          (5) The Company has complied with the notice and continuation of
coverage requirements of Section 4980B of the Code and the regulations
thereunder with respect to each plan that is, or was during any taxable year of
the Company for which the statute of limitations on the assessment of federal
income taxes remains open, by consent or otherwise, a group health plan within
the meaning of Section 4980B(g) of ERISA.

          (6) No Plan has incurred an "Accumulated Funding Deficiency" (as
defined in Section 302(a) of ERISA or Section 412(a) of the Code), whether or
not waived.

          (7) Neither the Company nor any ERISA Affiliate has incurred or would
incur a "withdrawal" or "partial withdrawal," as defined in Sections 4203 and
4205 of ERISA, from

                                      -11-

     3.10 Real Property.
          -------------

          (1) The Company owns no real property.

          (2) Schedule 3.10(b) sets forth a list and description of all real
property leases and subleases under which the Company is tenant or subtenant
(the "Leases"), including the date of the Lease, the premises demised
thereunder, the name of the lessee and lessor, the commencement date and
expiration date of the Lease and the annual rent payable by the lessee under the
Lease. As used herein, the term "Leased Real Property" shall mean the real
property demised by the Leases.

          (3) The Transferors have heretofore delivered to the Transferee true,
correct and complete copies of the Leases. Each of the Leases is in full force
and effect and is enforceable in accordance with its terms. The Company is in
possession of and quietly enjoys the Leased Real Property applicable to it and
the Company has a valid and enforceable leasehold interest, subject to no Liens
except such immaterial easements and rights-of-way, none of which interferes
with the operation of the business. No event has occurred or failed to occur
that, with the giving of notice or the passage of time or both, would constitute
a default under any Lease. The Company has not entered into any assignment of
any Lease, sublease of all or any portion of any Leased Real Property and no
person has any right to occupy the Leased Real Property other than the Company.

          (4) To the Transferor's knowledge, with respect to the Leased Real
Property (i) there is a right of ingress and egress to public thoroughfares to

land water supply facilities required for the present use of the Leased Real
Property are properly and fully installed and operating, and (iii) all curb cut

any part of the Leased Real Property to any adjoining public street have been
obtained and, if required, paid for by the Company and are in full force and
effect.

          (5) To the knowledge of the Transferors, all licenses, permits and
certificates of occupancy (the "Approvals"), in connection with the
construction, use, occupancy and maintenance of any Leased Real Property are in
full force and effect in accordance with the respective terms thereof, and none
of the Approvals has been amended, assigned, pledged or

                                      -12-



otherwise transferred. To the knowledge of the Transferors, there is no
alteration, improvement or change in use of any building or other improvement
located on the Leased Real Property that would require any new Approvals or
amendment of an existing Approval. To the knowledge of the Transferors, the
condition and use of the Leased Real Property conforms to each Approval. To the
knowledge of the Transferors, the Company is in compliance with all Laws
including, without limitation, those relating to zoning, building and land use
restrictions that are applicable to any portion of the Leased Real Property or
any buildings, plants or improvements owned by the Company.

          (6) To the knowledge of the Transferors, the Leased Real Property
including, without limitation, all building systems and equipment, all
structural components, the roof, the basement, all plumbing, electrical,
mechanical, heating, ventilating, air conditioning and sprinkler systems, and
all sewer, waste water, paving and parking equipment, systems and facilities,
are fully installed and, as applicable, operating, in good condition and repair,
ordinary wear and tear excepted, and adequate for the conduct of the business of
the Company as presently and proposed to be conducted, and there are no defects
in the same that would materially hinder or impair the business and operations
of the Company. The electricity service and all other public or private
utilities ("Utilities") serving the Leased Real Property are fully installed and
operating, adequate for the conduct of the business of the Company as presently
and proposed to be conducted, and enter the Leased Real Property through
adjoining public streets or through valid easements across adjoining private
lands, and, to the knowledge of the Transferors, all installation, connection
and capital recovery charges in connection with the Utilities have been paid in
full.

          (7) To the knowledge of each of the Transferors, there is no pending,
proposed, (i) annexation, condemnation, eminent domain or similar proceeding
affecting, or that may affect, all or any portion of the Leased Real Property,
(ii) proceeding to change or redefine the zoning classification of all or any
portion of the Leased Real Property, (iii) imposition of any special or other
assessments for public betterments or otherwise, (iv) special assessments
affecting the Leased Real Property or any portion thereof that are or would be
payable by the Company or any Transferor and could result in a Lien against any
of the Leased Real Property, (v) change in any applicable Laws in any material
manner relating to the use, occupation or operation of the Leased Real Property,
or (vi) tax certiorari proceeding with respect to any Leased Real Property.

          (8) Neither the Company nor any Transferor has received notice from
any insurance company or Board of Fire Underwriters (or organization exercising
functions similar thereto) or from any mortgagee requesting the performance of
any work or alteration in respect of any of the Leased Real Property, and, to
the best knowledge of each of the Company and the Transferors, there are no
outstanding requirements or recommendations from any of the foregoing.

          (9) There has been no damage to any portion of the Leased Real
Property within the last 24 months caused by fire or other casualty that has not
been repaired.

with a view to their distribution within the meaning of Section 2(11) of the
Securities Act. MedSource and the Transferee understand that they must bear the
economic risk of the investment indefinitely because such shares may not be
sold, hypothecated or otherwise disposed of unless subsequently registered under

acquiring certain property in exchange for cash and stock of MedSource

transactions contemplated by this Agreement or, its receipt, examination, filing
of or commenting on any Tax Return, and shall be separate and independent of any
other indemnity between the parties hereto.

          (3) MedSource or the Transferee shall promptly forward to the
Transferors a copy of all written communications from any Taxing Authority
received by the Taxpayer relating to any Pre-Closing Period. Each Transferor
shall promptly forward to the Transferee a copy of all written communications
from any Taxing Authority received by the Company (on or before the Closing
Date) or any Transferor relating to the Company or any Tax for which the Company
is or may be liable or that could result in a Lien on the stock of the Company
or any of its assets.

          (4) (i) Neither MedSource nor the Transferee shall settle or make any
payment of any amount claimed to be due with respect to a proposed adjustment
described above for at least 15 days after giving notice thereof to the
Transferors under section 5.3(c) hereof.

               (1) Notwithstanding any provision to the contrary in this section
5.3(d), the Transferors shall have the right, at their option (in the manner
provided in clause (iii)), to assume control of the defense of any Tax
Proceeding that relates solely to Taxes of the Company for a Pre-Closing Period
if, and only if, such Tax Proceeding or the resolution thereof could not have an
adverse impact on the Tax liability (an "Adverse Tax Impact") of MedSource, the
Transferee, the Company or any of their Affiliates. Any determination of whether
or not there could be an Adverse Tax Impact shall be made without regard to the
Tax attributes (including, without limitation, any net operating loss or tax
credit) of MedSource, the Transferee, the Company or any of their Affiliates
other than (A) the Tax basis of its assets or (B) any Tax attributes arising as
a result of the resolution of such Tax Claim. If the Transferors assume control,
the Transferors shall defend such Tax Proceeding in good faith and may use legal
counsel selected by them, provided such legal counsel is reasonably acceptable
to the Transferee. The Transferors shall keep the Transferee apprised as to the
status of such Tax Proceeding and any proceedings with respect thereto,
including, without limitation, the positions taken by the parties. The costs of
such defense shall be borne solely by the Transferors. MedSource and the
Transferee (or their designees) shall have the right, at their expense, to
participate in such defense, including, without limitation, to attend any
meetings and to be represented by legal counsel selected by it. Notwithstanding
anything herein to the contrary, no Transferor shall suggest, negotiate for or
agree to any position that could have an Adverse Tax Impact on

                                      -31-



MedSource, the Transferee, the Company or any of their Affiliates without the
prior written consent of MedSource and the Transferee, which consent shall not
be unreasonably withheld.

               (2) The Transferors shall assume control of a Tax Proceeding
under clause (ii) above by written notice to MedSource and the Transferee within
15 days after notice of the Tax Proceeding pursuant to section 5.3(c), stating
that the Transferors are undertaking and will prosecute the defense of such Tax
Proceeding, the Tax Proceeding is subject to the indemnification provisions of
section 5.3(b) and that the Transferors will be able to pay the full amount of
the potential liability in connection with such Tax Proceeding. The right of the
Transferors to control any defense under this section 5.3 shall be limited to
the items and amounts in dispute for which the Transferors would be liable to
indemnify MedSource, the Transferee, the Company or their Affiliates.

               (3) MedSource, the Transferee and the Transferors shall cooperate
with each other in contesting any Tax Proceeding, including, without limitation,
the provision of records and information which are reasonably relevant to such
Tax Proceeding and making individuals available on a mutually convenient basis
to provide additional information or explanation of any material provided
hereunder.

          (5) Any Taxes for a period which includes but does not end on the
Closing Date shall be allocated between the Pre-Closing Period and the balance
of the period in accordance with this section 5.3(e). To the extent permitted
under applicable Law, the parties shall elect to treat the Tax period as ending
at the close of the Closing Date. Where applicable Law does not permit such an
election to be made, the taxable income or other Tax base for the entire period
shall be allocated between the period on or before the Closing Date and the
balance of the period on the basis of an interim closing of the books at the
close of the Closing Date, except that any real estate or personal property
Taxes shall be apportioned on the basis of the relative number of days in the
period on or before the Closing Date and in the balance of the period.

          (6) The Transferors shall duly and timely file all required stock
transfer and other transfer Tax Returns and pay when due any such Taxes in
connection with the transactions contemplated by this Agreement. The Transferors
shall promptly provide to MedSource and the Transferee a copy of any such Tax
Returns and proof of payment of any such Taxes.

          (7) After the Closing Date, neither MedSource nor the Transferee shall
amend any Tax Return of the Company that relates to a Pre-Closing Period if such
amendment would cause an adverse impact on the Tax liability of the Transferors
without the prior written consent of the Transferors, which shall not be
unreasonably withheld.

          (8) MedSource and the Transferee shall, for a period of six years
after the Closing, preserve all Tax Returns of the Company (and associated
records) that relate to any Pre-Closing Period and shall make them available to
Transferors or their authorized representatives

                                      -32-

order to make copies and extracts therefrom for any proper purpose, all such
inspection and copies to be made at the Transferors' sole expense. MedSource and

Agreement untrue or incorrect in any material respect, and (ii) all other
material developments affecting the Company condition (financial or other),
operations, results of operations, customer or supplier relations, employee
relations, projections or prospects of the Company or its business. Should the

Agreement was the date of the occurrence of any such fact or condition), the
Transferors shall promptly deliver to MedSource and the Transferee a supplement

5.7(a) shall be construed as a series of separate covenants, one for each state
or country specified. Except for geographic coverage, each such separate
covenant shall be deemed identical in terms to the covenant contained in section
5.7(a) above. If, in any judicial proceeding, a court shall refuse to enforce
any of the separate covenants deemed included in section 5.7(a), then such
unenforceable covenant shall be deemed reduced in scope or, if necessary,
eliminated from these provisions for the purpose of those proceedings to the
extent necessary to permit the remaining separate covenants to be enforced.

section 5.7, and the period of time, geographic area and scope and type of

substance satisfactory to the Transferee's lender, providing, inter alia that

Restated Lease so that it will be treated as an operating lease for financial
accounting purposes. The Transferee shall agree to a reasonable collateral
assignment of payments under the Restated Lease.

Transferee Indemnitee harmless from, any loss, liability, obligation,
deficiency, damage or expense including, without limitation, interest,

Transferor contained in this Agreement or in any other Transaction Document or
in respect of any third party claim made based upon facts alleged which, if
true, would constitute any such breach;

          (2) any Transferor's failure to perform or to comply with any covenant
or condition required to be performed or complied with by the Transferors
contained in this Agreement or in any other Transaction Document; or

          (3) the ownership or operation of the Company on or prior to the

     10.3 Indemnification Procedures.
          --------------------------

                                      -46-



          (1) Promptly after notice to an indemnified party of any claim or the
commencement of any Proceeding, including any Proceeding by a third party,
involving any Damage referred to in sections 10.1 or 10.2, such indemnified
party shall, if a claim for indemnification in respect thereof is to be made
against an indemnifying party pursuant to this section 10, give written notice
to the latter of the notice of such claim or the commencement of such
Proceeding, setting forth in reasonable detail the nature thereof and the basis
upon which such party seeks indemnification hereunder; provided, however, that
                                                       --------  -------
the failure of any indemnified party to give such notice shall not relieve the
indemnifying party of its obligations under such section, except to the extent
that the indemnifying party is actually prejudiced by the failure to give such
notice.

          (2) (i) In the case of any Proceeding by a third party against an
indemnified party, the indemnifying party shall, upon notice as provided above,
assume the defense thereof, with counsel reasonably satisfactory to the
indemnified party, and, after notice from the indemnifying party to the
indemnified party of its assumption of the defense thereof, the indemnifying
party shall not be liable to such indemnified party for any legal or other
expenses subsequently incurred by the indemnified party in connection with the
defense thereof (but the indemnified party shall have the right, but not the
obligation, to participate at its own cost and expense in such defense by
counsel of its own choice) or for any amounts paid or foregone by the
indemnified party as a result of any settlement or compromise thereof that is
effected by the indemnified party (without the written consent of the
indemnifying party).

               (ii) Anything in section 10.3(b)(i) notwithstanding, if both the
indemnifying party and the indemnified party are named as parties or subject to
such Proceeding and either such party determines with advice of counsel that
there may be one or more legal defenses available to it that are different from
or additional to those available to the other party or that a material conflict
of interest between such parties may exist in respect of such Proceeding, then
the indemnifying party may decline to assume the defense on behalf of the
indemnified party or the indemnified party may retain the defense on its own
behalf, and, in either such case, after notice to such effect is duly given
hereunder to the other party, the indemnifying party shall be relieved of its
obligation to assume the defense on behalf of the indemnified party, but shall
be required to pay any legal or other expenses including, without limitation,
reasonable attorneys' fees and disbursements, incurred by the indemnified party
in such defense.

               (iii) If the indemnifying party assumes the defense of any such
Proceeding, the indemnified party shall cooperate fully with the indemnifying
party and shall appear and give testimony, produce documents and other tangible
evidence, allow the indemnifying party access to the books and records of the
indemnified party and otherwise assist the indemnifying party in conducting such
defense. No indemnifying party shall, without the consent of the indemnified
party, consent to entry of any judgment or enter into any settlement or
compromise which does not include as an unconditional term thereof the giving by
the claimant or plaintiff to such indemnified party of a release from all
liability in respect of such claim or Proceeding. Provided

                                      -47-



that proper notice is duly given, if the indemnifying party shall fail promptly
and diligently to assume the defense thereof, then the indemnified party may
respond to, contest and defend against such Proceeding (but the indemnifying
party shall have the right to participate at its own cost and expense in such
defense by counsel of its own choice) and may make in good faith any compromise
or settlement with respect thereto, and recover from the indemnifying party the
entire cost and expense thereof including, without limitation, reasonable
attorneys' fees and disbursements and all amounts paid or foregone as a result
of such Proceeding, or the settlement or compromise thereof. The indemnification
required hereunder shall be made by periodic payments of the amount thereof
during the course of the investigation or defense, as and when bills or invoices
are received or loss, liability, obligation, damage or expense is actually
suffered or incurred. The provisions of sections 10.3 and 10.4 shall not apply
to claims under section 5.3.

               (iv) Any indemnification payment under this Agreement shall be
treated as an adjustment to the Consideration.

     10.4 Limitations on Indemnification.
          ------------------------------

               (1) The Transferors shall have indemnification obligations
pursuant to section 10.1(a) respecting Damages that result from actual or
claimed breaches of representations or warranties set forth in this Agreement
(other than the representations and warranties contained in sections 3.2, 3.3,
3.12(a), 3.14, 3.16 and 3.17), only if and only to the extent that the aggregate
of all Damages resulting from such actual or claimed breaches shall exceed
$200,000. Anything to the contrary notwithstanding, no Transferor shall have any
liability pursuant to section 10.1(a) with respect to Damages that result from
actual or claimed breaches of representations or warranties set forth in this
Agreement (other than the representations and warranties contained in sections
3.2, 3.3, 3.12(a), 3.14, 3.16 and 3.17) for and to the extent that the aggregate
amount of such Damages exceeds $3,762,000. For the purposes of determining
whether any Transferee Indemnitee is able to seek indemnification from the
Transferors under section 10.1(a) for any breach or alleged breach of any
representation or warranty in this Agreement, the use of the terms "knowledge"
or "material" shall be disregarded and any and all claims for such
indemnification shall be determined as if no such terms were present in such
representation or warranty. The parties hereto expressly acknowledge that the
sole purpose for using the terms "knowledge" and "material" is to determine
whether the conditions set forth in section 6.1 have been satisfied.

               (2) The limitations set forth in paragraph (a) of this section
10.4 shall not limit or reduce the Transferors' obligations to indemnify
MedSource or the Transferee in respect of Damages that result from actual or
claimed breaches of the representations and warranties contained in sections
3.2, 3.3, 3.12(a), 3.14, 3.16 and 3.17.

               (3) MedSource and the Transferee shall have indemnification
obligations pursuant to section 10.2(a) respecting Damages that result from
actual or claimed breaches of representations or warranties set forth in this
Agreement (other than the representations and

                                      -48-



warranties contained in section 4.13), only if and only to the extent that the
aggregate of all Damages resulting from such actual or claimed breaches shall
exceed $200,000. Anything to the contrary notwithstanding, MedSource and the
Transferee shall have no liability pursuant to section 10.2(a) with respect to
Damages that result from actual or claimed breaches of representations or
warranties set forth in this Agreement for and to the extent that the aggregate
amount of such Damages exceeds $3,762,000.

          (4) In the event that any Damages of MedSource or the Transferee are
covered by insurance proceeds or other reimbursement obligations, whether
maintained by MedSource, the Transferee or the Company, neither MedSource nor
the Transferee shall be deemed to have any Damages if and to the extent that
MedSource or the Transferee actually realizes the proceeds of such insurance,
which payments shall in no event be included in the basket set forth in section
10.4(a).

          (5) As used in this Agreement, (i) an individual will be deemed to
have "knowledge" of a particular fact or matter if such individual is actually
aware of such fact or other matter or a prudent individual could be expected to
discover or otherwise become aware of such fact or other matter in the course of
conducting a reasonably comprehensive investigation concerning the existence of
such fact or other matter and (ii) a Person (other than an individual) will be
deemed to have "knowledge" or a particular fact or matter if any individual who
is serving, or has at any time served, as a director, officer, partner, executor
or trustee of such Person (or in any similar capacity) has, or at any time had,
"knowledge" of such fact or other matter.

     10.5 Right to Set-Off. MedSource and the Transferee shall have the right to
          ----------------
set-off the amount of any and all Damages for which the Transferors may become
liable to the Transferee hereunder against any sums otherwise payable to any
Transferor hereunder or under any other agreement, document or instrument
executed and delivered pursuant to this Agreement or contemplated hereby (other
than wages under the Employment Agreements). Neither MedSource nor the
Transferee will exercise any right to set-off until it has given the Transferors
not less than 10 days notice within which period the Company and the Transferors
shall have the right to pay the amount of the Damages proposed by MedSource and
the Transferee in cash. The remedies provided herein shall be cumulative and
shall not preclude assertion by any party hereto of any other rights or the
seeking of any other remedies against any other party hereto.

11. Miscellaneous.

     11.1 Transaction Fees and Expenses. Except as otherwise expressly provided
          -----------------------------
herein, each party hereto shall bear such costs, fees and expenses as may be
incurred by it in connection with this Agreement and the transactions
contemplated hereby.

                                      -49-



     11.2 Notices. Any notice, demand, request or other communication which is
          -------
