under the laws of its jurisdiction of organization, (ii) has all
requisite corporate power and authority to own, lease and operate

standing under the laws of each of the jurisdictions listed on

                             -5-

<PAGE>

under lease or license or TATRA's business, as presently conducted,
requires such qualification or authorization, except where the

after such date, each as filed with the Securities and Exchange
Commission (the "Commission") (collectively, the "SEC Reports").
Each SEC Report was in compliance in all material respects with
the requirements of its respective report form and did not on the
date of filing contain any untrue statement of a material fact or
omit to state a material fact required to be stated therein or
necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading, and as
of the date hereof there are no fact or facts not disclosed in
the SEC Reports which individually or in the aggregate may have a
Material Adverse Effect.

     3.6.    Financial Statements.  The financial statements

SEC Reports have been prepared in accordance with generally
accepted accounting principles ("GAAP") consistently followed
(except as indicated in the notes thereto) throughout the periods
involved and fairly present in all material respects the
consolidated financial condition, results of operations and
changes in stockholders' equity of the Company as of the
respective dates thereof and for the respective periods then
ended (in each case subject, as to interim statements, to changes
resulting from year-end adjustments, none of which were material
in amount or effect).  Except as set forth in Schedule 3.6, the
Company has no liabilities or obligations, contingent or
otherwise, except (i) liabilities and obligations in the
respective amounts reflected or reserved against in the Company's

to in the financial statements of the Company (or the notes
thereto) for the year ended December 31, 2000 included in the SEC
Reports, except in each case for such defects in title and such
other liens and encumbrances which do not individually or in the
aggregate materially detract from the value to the Company of the
properties and assets of the Company and its Subsidiaries taken
as a whole. The assets and properties owned by, or leased to, the
Company and its Subsidiaries, are all of the assets and
properties necessary for the Company and its Subsidiaries to
operate their respective businesses as now being conducted and as
contemplated to be conducted. The Company and its Subsidiaries
maintain insurance in such amounts (to the extent available in
the public market), including self-insurance, retainage and
deductible arrangements, and of such a character as is reasonable
and customary for companies engaged in the same or similar
business.

     3.9.    Consents.  Assuming the accuracy of the
representations of the Purchaser set forth in Sections 4.5 and
4.7, except as set forth on Schedule 3.9, the Company is not

     3.11.   Taxes.  Each Company Entity has filed all Tax Returns
required to be filed. All such Tax Returns are true, correct and
complete, except for such instances which individually or in the
aggregate would not have or reasonably be expected to have a
Material Adverse Effect. All Taxes of any Company Entity which
are (i) shown as due on such Tax Returns, (ii) otherwise due and.
payable or (iii) claimed or asserted by any taxing authority to
be due, have been paid, except for those Taxes being contested in
good faith and for which adequate reserves have been established

Company Entity knows of any proposed or threatened Tax claims or
assessments which, if upheld, would individually or in the
aggregate have a Material Adverse Effect or a Material Adverse
Change. Each Company Entity has withheld and paid over to the
relevant Taxing authority all Taxes required to have been
withheld and paid in connection with payments to employees,
independent contractors, creditors, stockholders or other third
parties, except for such Taxes which individually or in the
aggregate would not have a Material Adverse Effect or a Material
Adverse Change.

     3.12.   Employee Benefit Plans.  None of the Company Entities
nor any ERISA Affiliate presently sponsors, maintains,
contributes to, nor are any of the Company Entities or any ERISA
Affiliate required to contribute to, nor has any Company Entity
or any ERISA Affiliate ever sponsored, maintained, contributed
to, or been required to contribute to any "employee pension
benefit plan" (within the meaning of Section 3(2) of ERISA) or
any "multiemployer plan" (within the meaning of Section 3(37) or
Section 4001(a)(3) of ERISA). The execution of, and performance
of the transactions contemplated in, this Agreement will not
(either alone or upon the occurrence of any additional or
subsequent events (i) constitute an event that will or may result
in any payment (whether of severance pay or otherwise),
acceleration, forgiveness of indebtedness, vesting, distribution,
increase in benefits or obligation to fund benefits with respect
to any employee, (or) (ii) result in the payment of an "excess
parachute payment" (within the meaning of Section 280G(b)(1) of
the Code). Each "employee benefit plan" (as defined in Section
3(3) of ERISA) maintained or contributed to by the Company for
the benefit of its employees (an "Employee Plan") has been
maintained in accordance with its terms and all provisions of
applicable law. To the best knowledge of the Company, no
"prohibited transaction" (within the meaning of Section 4975 of
the Code or Section 406 of ERISA) has occurred with respect to
any Employee Plan.

     3.13.   Intellectual Property Rights.  (a) Each of the Company
Entities owns the entire right, title and interest in and to the

Intellectual Property are valid, subsisting, enforceable and in
full force and effect, and all patent applications, copyright
applications and trademark applications with respect to the
Intellectual Property are pending and in good standing, all
without challenge of any kind and no aspect thereof is subject to
any outstanding order, ruling, decree, judgment or stipulation by
or with any governmental authority or arbitrator, in each case,
except as would not have or would not reasonably be expected to
have a Material Adverse Effect. The Company Entities have each
taken and are presently taking all steps necessary to prevent any
impairment of its right to make use

                            -8-

<PAGE>

of the Intellectual Property, and the Company Entities have filed
all appropriate renewals, extensions, affidavits of continued use
and/or incontestability and has paid all fees associated therewith,
necessary to maintain the Intellectual Property, except where such
failure would not have or would not reasonably be expected to have a
Material Adverse Effect. There is no claim or demand of any Person
or dispute with any Person with respect to any Intellectual
Property, except where such claim or demand would not have and
would not reasonably be expected to have a Material Adverse
Effect.

              (b)     To the best of the Company's knowledge, no
Company Entity has interfered with, infringed upon or
misappropriated any intellectual property right of any third
party nor does any interference, infringement, or
misappropriation result from the development, use, or sale of any
of the Company Entities' products. No Company Entity has received
any charge, complaint, claim, demand or notice alleging any such
interference, infringement or misappropriation (including any
claim that it must license or refrain from using any intellectual
property right of any third party), nor do any of the Company
Entities have knowledge or any basis for any such claim. To the
best knowledge of the Company Entities, no third party has
interfered with, infringed upon, misappropriated or otherwise
used (whether or not such use constitutes infringement) any
Intellectual Property, except where such interference,
infringement or misappropriation would not have or would not
reasonably be expected to have a Material Adverse Effect.

              (c)     No Company Entity has disclosed any of its
proprietary information that, if disclosed; would materially

performance of their duties to the Company, (ii) in connection
with entering into this Agreement, (iii) to governmental

participated in the conception and development of the
Intellectual Property on behalf of the Company Entities either:

with any of the Company Entities, in accordance with applicable
federal and state law, that has accorded any of the Company
Entities full, effective, exclusive, and original ownership of
all tangible and intangible property and rights thereby arising;
or (ii) have executed appropriate instruments of assignment in
favor of any Company Entity as assignee that have conveyed to the
Company Entities full, effective, and exclusive ownership of all

Entities possess all franchises, certificates, licenses, permits
and other authorizations from Governmental Entities and other
rights, free from burdensome restrictions, that are necessary for
the ownership, maintenance and operation of its respective
properties and assets, except for those the absence of which

Company Entity is a party to any contract or subject to any
charter or by-law provision or any judgment or decree which
individually or in the aggregate has or is reasonably likely to
have a Material Adverse Effect. Neither the execution and
delivery of any of the Transaction Documents, nor the fulfillment
of or compliance with the terms and provisions hereof or thereof
will conflict with or result in a breach of the terms,
conditions, or provisions of, or give rise to a right of
termination under, or constitute a default under, or result in
any violation of, the certificate of incorporation or by-laws of
any of the Company Entities or any contract of any of the Company
Entities. Each of the Contracts of the Company Entities is a
legal and binding agreement of the Company Entity party thereto
enforceable in accordance with its terms and is in full force and
effect, except where such failure would not individually or in

Adverse Effect. Neither the Company nor its Subsidiaries is in
default under any outstanding indenture or other debt instrument
or with respect to the payment of the principal of or interest on
any outstanding obligations for borrowed money, or is in default
under any other Contracts, except for defaults under such other

behalf of the Company in connection with the transactions
contemplated hereby, contains any untrue statement of a material
fact or, taken as a whole, omits to state a material fact

Rights Agreement and to consummate the transactions contemplated
hereby and thereby. The execution and delivery of this Agreement
and the Registration Rights Agreement by the Purchaser and the
compliance by the Purchaser with all of the provisions of this
Agreement and the Registration Rights Agreement and consummation
by the Purchaser of the transactions contemplated hereby and
thereby to which the Purchaser is a party have been duly
authorized by all necessary corporate action on behalf of the
Purchaser. This Agreement and the Transaction Documents to which
the Purchaser is a party have been duly executed and delivered by
the Purchaser and constitute the valid and binding agreements of
the Purchaser enforceable in accordance with their terms, except
that (i) such enforcement may be subject to bankruptcy,
insolvency, reorganization, moratorium or other similar laws now
or hereafter in effect relating to creditors' rights, and (ii)
the remedy of specific performance and injunctive and other forms
of equitable relief may be subject to equitable defenses and to
the discretion of the court before which any proceeding therefor
may be brought.

     4.3.    Consents.  Except as set forth on Schedule 4.3 or as
may be required by Czech Law or the rules and regulations of the
Securities Center, the Purchaser is not required to obtain any
consent, approval or authorization of, or to make any declaration
or filing with, any Governmental Entity or any other Person as a
condition to or in connection with the valid execution and
delivery of this Agreement or the Transaction

                            -13-

<PAGE>

Documents to which the Purchaser is a party or the performance by
the Purchaser of its obligations in respect hereof and thereof
except for filings that may be required by the Exchange Act.

     4.4.    Conflicting Agreements.  Neither the execution and
delivery of this Agreement or any other Transaction Document to
which the Purchaser is a party nor the fulfillment of or
compliance with the terms and provisions hereof or thereof will
conflict with or result in a breach of the terms, conditions or
provisions of, or give rise to a right of termination under, or
constitute a default under, or result in any violation of the
organizational documents of the Purchaser or any contract to
which the Purchaser or any of its respective properties is
subject.

     4.5.    Acquisition for Investment.  The Purchaser is
acquiring the TATRA Shares and Company Shares (together, the
"Securities") being purchased by it for its own account for the
purpose of investment and not with a view to or for sale in
connection with any distribution thereof except in compliance
with all applicable securities Laws. The Purchaser acknowledges
that the Securities have not been registered under the Securities
Act or any state securities laws, and may be sold or disposed of
in the absence of such registration only pursuant to an exemption
from such registration and, in the case of the TATRA Shares, in
accordance with this Agreement.

     4.6.    Brokers or Finders.  No agent, broker, investment
banker or other Person is or will be entitled to any broker's fee
or any other commission or similar fee from the Purchaser in
connection with any of the transactions contemplated by this
Agreement or the Transaction Documents for which the Company will
be responsible.

     4.7.    Accredited Investor.  The Purchaser is an "accredited
investor" within the meaning of Rule 501 promulgated under the
Securities Act.

     SECTION 5.  Buy/Sell; Corporate Governance; Management
Fees; Shareholders Agreement.

     5.1.    Buy/Sell.  Purchaser and SDC Prague (each, a "Holder")
each agree that if either party proposes to cause a buy/sell of
their Contract Shares as provided for in this Section 5.1, such
Holder (a "Proposing Holder") shall first deliver to the other
Holder (such Holder, a "Receiving Holder") a written notice of
the Proposing Holder's intent and each Holder shall then engage,
at its own expense, within 20 days from the date of delivery of
such notice (the "Notice Date"), an independent appraiser, who
shall work with the other Holder's independent appraiser to
determine the appraised value (the "Appraised Value") of 100% of
the registered capital of TATRA. If either Holder shall fail to
appoint an independent appraiser within such 20 day period, then
the appraiser appointed by the Holder that does so appoint an
appraiser shall make the determination of the Appraised Value for
all purposes hereof. If after 30 days from the Notice Date, the
Holders' respective independent appraisers cannot agree on the
Appraised Value, then the Holders' respective independent
appraisers shall engage at the Holders' mutual expense a mutually
acceptable third independent appraiser, who shall conclusively
determine the Appraised Value. If the two appraisers cannot
mutually agree on a third appraiser within

                            -14-

<PAGE>

10 days, the president of the American Arbitration Association
shall be immediately requested by either of the Holders to select
the third appraiser, who shall make such determination of Appraised
Value, within 20 days after being selected. Upon determination of
the Appraised Value, the Receiving Holder shall determine, within
30 days from the date that the Appraised Value is finally
determined, whether to (x) sell all of its Contract Shares or
(y) purchase all of the Proposing Holder's Contract Shares (the
"Buy/Sell Determination"), in either case at a price per Contract
Share based on the Appraised Value (the "Buy/Sell Purchase Price"),
and notify the Proposing Holder of its determination in writing and
the Proposing Holder will be bound by such determination. Such
purchase or sale shall be consummated within 90 days from the
date the Receiving Holder notifies the Proposing Holder of its
determination. If the Proposing Holder does not receive the
Receiving Holder's Buy/Sell Determination within 30 days from the
date the Appraisal Value is determined, the Proposing Holder may
make a Buy/Sell Determination, by which the Receiving Holder will
be bound. At the closing of the purchase or sale, as the case may
be, the purchasing Holder shall cause to be paid to the selling
Holder the Buy/Sell Purchase Price with respect to the Contract
Shares being sold, by wire transfer of immediately available
funds, against delivery by the selling Holder of duly executed
transfer instruments (in form and substance reasonably
satisfactory to the purchasing Holder) transferring such Holder's
Contract Shares free and clear of all Encumbrances.

     5.2.    Corporate Governance.  Each Holder agrees that it will
take any and all actions to ensure that as soon as possible after
the Closing (1) the supervisory board of TATRA (the "Supervisory
Board") shall be composed of one labor representative and one
representative of Purchaser and Ronald A. Adams, (ii) Ronald A.
Adams becomes Chairman of the Supervisory Board, (iii) the
relevant organizational documents of TATRA are amended to provide
that any change in the composition of the Supervisory Board will
require the affirmative vote of two-thirds of the registered
capital of TATRA until such time as the Purchaser shall, directly
or indirectly, have a majority interest in the registered capital
of TATRA, (iv) any members of the Board of Directors of TATRA who
are required to be citizens of the Czech Republic shall be
appointed by the Supervisory Board, which shall be composed of
three members, one of whose members shall be Milota Srkal, and
(v) Milota Srkal becomes chairman of the Board of Directors of
TATRA.

     5.3.    Management Fees.  Each Holder agrees that it will
cause TATRA to reimburse Purchaser and the Company for actual
management-related services performed by Purchaser or the
Company, as the case may be, in accordance with terms and
conditions to be agreed upon between each Holder as soon as
practicable after the date hereof. After the first anniversary of
the date hereof, the management fees contemplated by this Section
5.3 shall be paid in amounts to be agreed upon by the Holders.

     5.4.    Shareholders Agreement.  After the Closing, the
Holders agree to cause TATRA to adopt, as soon as is reasonably
possible, a shareholders agreement (the "Shareholders Agreement")
containing terms substantially similar to those contained in this
Section 5. Once the Shareholders Agreement is executed and
delivered by the Holders and adopted in accordance with Czech
law, this Section 5 shall be deemed to be

                            -15-

<PAGE>

amended to conform to the terms of the Shareholders' Agreement.
The Company agrees that it shall cause SDC Prague to fulfill its
obligations pursuant to this Section 5.

     5.5.    Further Purchases.  (a) In the event that additional
shares of the registered capital of TATRA are purchased pursuant
to a tender offer made pursuant to Section 183b of the Czech
Commercial Code, each Holder agrees to take all action necessary
to maintain the same proportionate ownership in the registered
capital of TATRA as shall exist on the Closing Date (the "Status
Quo").

             (b)     In the event that SDC Prague or the Company or
any Affiliate of SDC Prague or the Company (an "Acquiring
Affiliate") acquires additional shares of the registered capital
of TATRA ("Additional TATRA Shares"), SDC Prague, the Company or
the Acquiring Affiliate shall offer such number of the acquired
shares to Purchaser as is necessary to maintain the Status Quo at
the same price that SDC Prague, the Company or the Acquiring
Affiliate paid for the acquired shares. For purposes of this
Section 5.5(b), any Additional TATRA Shares held by an Acquiring
Affiliate will be deemed to be owned by SDC Prague.

             (c)     The Purchaser agrees that it will not acquire
shares or other ownership interests of SDC Prague or TATRA (other
than pursuant to the Czech Pledges) if (x) after such
acquisition, the Company is unable to include results of TATRA,
on a consolidated basis, in its consolidated financial statements
under GAAP and (y) the Company has delivered to the Purchaser the
written opinion of KMPG to that effect.

     5.6.    Cooperation.  Because the Purchaser will be a
shareholder of TATRA and a potential shareholder of SDC Prague,
the Purchaser has an economic incentive to encourage the growth
of the value of TATRA. As a result, the Purchaser will work with
TATRA in good faith to (a) explore reciprocal marketing
arrangements between TATRA and the Purchaser where selected
products of each company is marketed through the other's
distribution under a "TATRA-Terex" or similar badge, and (b)
explore in good faith the use of subsidiaries of TATRA as
component suppliers. With respect to the component supply
opportunity, in order for the TATRA Subsidiaries to receive the
Terex component supply orders, the TATRA Subsidiaries must be
competitive with alternative Purchaser suppliers with respect to
price and quality. The Purchaser will also explore the use of the
engineering and test capabilities of TATRA, further improving the
utilization of its personnel and capital resources. All
commercial transactions between TATRA and the Purchaser will be
on an arm's-length, negotiated basis.

     SECTION 6.  Certain Taxes.  The Company agrees that it will
pay, and will hold the Purchaser harmless from, any and all
liability with respect to any transfer, transfer gains, stamp or
similar Taxes which may be determined to be payable in connection
with the execution and delivery and performance of this Agreement
or any modification, amendment or alteration of the terms or
provisions of this Agreement or any of the Transaction Documents.

                            -16-

<PAGE>

     SECTION 7.  Legends; Exchanges; Lost, Stolen or Mutilated
Certificates.  (a)  Each certificate representing shares of
Securities shall bear a legend containing the following words:

"THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE
NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933
OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE
SOLD OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN
EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT AND
APPLICABLE STATE SECURITIES LAWS OR AN APPLICABLE
EXEMPTION TO THE REGISTRATION REQUIREMENTS OF SUCH ACT
OR SUCH LAWS."

             The requirement that the first paragraph of the
foregoing legend be placed upon certificates evidencing any such
Securities shall cease and terminate upon the earliest of the
following events:  (i) when such shares are transferred in a
public offering under the Securities Act, (ii) when such shares
are transferred pursuant to Rule 144 under the Securities Act or
(iii) when such shares are transferred in any other transaction
if the seller delivers to the Company an opinion of its counsel,
which counsel and opinion shall be reasonably satisfactory to the
Company, or a "no-action" letter from the staff of the
Commission, in either case to the effect that such legend is no
longer necessary in order to protect the Company against a
violation by it of the Securities Act upon any sale or other
disposition of such shares without registration thereunder. Upon
the occurrence of any event requiring the removal of a legend
hereunder, the Company, upon the surrender of certificates
containing such legend, shall, at its own expense, deliver to the
holder of any such shares as to which the requirement for such
legend shall have terminated, one or more new certificates
evidencing such shares not bearing such legend.

             (b)     Upon surrender by the Purchaser to the Company of
any certificate representing Common Stock purchased or acquired
hereunder, the Company at its expense will, within five business
days, issue in exchange therefor, and deliver to the Purchaser, a
new certificate or certificates representing such shares, in such
denominations as may be requested by the Purchaser. Upon receipt
of evidence satisfactory to the Company of the loss, theft,
destruction or mutilation of any certificate representing any
share of Common Stock purchased or acquired by the Purchaser
hereunder, and in case of any such loss, theft or destruction,
upon delivery of any indemnity agreement satisfactory to the
Company, or in any case of any such mutilation, upon surrender
and cancellation of such certificate, the Company at its expense
will, within five business days, issue and deliver to the
Purchaser a new certificate for such Common Stock of like tenor,
in lieu of such lost, stolen or mutilated certificate.

     SECTION 8.  Survival of Representations, Warranties,
Agreements and Covenants, Etc.  All representations and
warranties hereunder shall be deemed to be made solely as of the
date of this Agreement and shall survive the Closing until each
of the Second Note and the Third Note shall have been redeemed,
or otherwise paid in full, other than the representations and
warranties made in the last two sentences of Section 3.3, which
shall survive indefinitely. None of the representations and
warranties shall be

                            -17-

<PAGE>

affected by any knowledge possessed by, or investigation of the
subject matter thereof made by or on behalf of, the Purchaser. All
statements contained in any schedule to this Agreement or in any
certificate or other instrument delivered by the Company pursuant
to Section 2.3 shall constitute representations and warranties by
the Company under this Agreement. All covenants and agreements
contained herein shall survive indefinitely until, by their
respective terms, they are no longer operative.

     SECTION 9.  Purchaser Director.

     9.1.    Right of the Purchaser to Designate Director.  At any
time after, and for so long as, the Purchaser holds at least
fifteen percent (15%) of the outstanding shares of Common Stock,
at the Purchaser's request, the Company shall cause one person
designated by the Purchaser to be nominated, and shall use its
best efforts to cause such person to be elected or appointed
(whether in connection with a newly created vacancy, removal or
otherwise) to the Board of Directors of the Company (the "Board")
effective, without any further action, within five days after
such person is designated by the Purchaser and at each annual
meeting of stockholders occurring thereafter (any person
designated by the Purchaser pursuant to this Section 9.1 from
time to time and elected or otherwise appointed, a "Purchaser
Designee"). In connection with any annual meeting of stockholders
at which the term of the Purchaser Designee is to expire, the
Company will take all necessary action to include the Purchaser
Designee as one of management's nominees for director and use the
same efforts to cause such Purchaser Designee to be elected to
the Board as are used with respect to management's other
nominees. In the event of any vacancy arising by reason of the
resignation, death, removal or inability to serve of any
Purchaser Designee, the Purchaser shall be entitled to designate
a successor to fill such vacancy for the unexpired term. The
Purchaser Designee shall be subject to the reasonable approval of
the Company except if the Purchaser Designee is a bona fide
employee of, or regular consultant to, Purchaser or any of its
Affiliates (in which case such approval shall not be necessary).

     9.2.    Board and Committee Notice Requirement.  In addition
to any requirements specified in the By-Laws of the Company, the
Company shall notify the Purchaser Designee by telecopy of every
meeting (or action by written consent) of the Board and of any
committee of the Board, at least three days in advance of such
meeting (or distribution of written consents).

     9.3.    Reimbursement of Certain Expenses.  The Company shall,
upon request therefor, promptly reimburse the Purchaser Designee
for all reasonable expenses incurred by him in connection with
his attendance at meetings of the Board or of committees of the
Board and any other activities undertaken by him in his capacity
as a director of the Company or any Subsidiary, as applicable to
the same extent as the Company would reimburse any other director
in respect of such activities. The foregoing shall be in addition
to, and not in lieu of (or in duplication of), any
indemnification or reimbursement obligations of the Company under
the Certificate of Incorporation Or By-Laws of the Company or by
Law.

                            -18-

<PAGE>

     9.4.    Directors' Indemnification; Insurance.  (a)  To the
extent commercially available, the Company shall at all times
maintain directors' and officers' liability insurance comparable
in terms and coverage to that maintained on the date hereof, and
the Purchaser Designee shall be covered under such insurance.

             (b)     The Certificate of Incorporation, By-Laws and
other organizational documents of the Company shall at all times,
to the fullest extent permitted by law, provide for
indemnification of, advancement of expenses to, and limitation of
the personal liability of, the members of the Board. Such
provisions may not be amended, repealed or otherwise modified in
any manner adverse to any member of the Board until at least six
years following the date that the Purchaser Designee is no longer
a member of the Board.

             (c)     The Purchase Designee is intended to be a third-
party beneficiary of the obligations of the Company pursuant to
this Section 9.4, and the obligations of the Company pursuant to
this Section 9.4 shall be enforceable by the Purchaser Designee.

     SECTION 10.  Standstill.  (a)  Except as otherwise
expressly provided in this Agreement or the Transaction Documents
or as specifically approved by a majority of the independent
directors (so long as such approval was not obtained by the
Purchaser in violation of this Agreement), during the period
commencing on the date hereof and continuing until December 31,
2003, Purchaser shall not, directly or indirectly, (i) by
purchase or otherwise, Beneficially Own, acquire, agree to
acquire or offer to acquire any Voting Securities or direct or
indirect rights or options to acquire Voting Securities other
than the Company Shares and shares of Common Stock issuable upon
conversion of the Notes, (ii) enter, propose to enter into,
solicit or support any merger or business combination or similar
transaction involving the Company or any of its Subsidiaries, or
purchase, acquire, propose to purchase or acquire or solicit or
support the purchase or acquisition of any portion of the
business or assets of the Company or any of its Subsidiaries
(except for proposals to purchase or acquire a non-material
portion of the assets of the Company or any of its Subsidiaries
that are not required to be publicly disclosed), (iii) initiate
or propose any securityholder proposal without the approval of
the Board granted in accordance with this Agreement or make, or
in any way participate in, any "solicitation" of "proxies" (as
such terms are used in the proxy rules promulgated by the
Commission under the Exchange Act) to vote, or seek to advise or
influence any Person with respect to the voting of, any Voting
Securities or request or take any action to obtain any list of
securityholders for such purposes with respect to any matter (or,
as to such matters, solicit any Person in a manner that would
require the filing of a proxy statement under Regulation 14A of
the Exchange Act), (iv) form, join or in any way participate in a
Group formed for the purpose of acquiring, holding, voting or
disposing of or taking any other action with respect to Voting
Securities that would be required under Section 13(d) of the
Exchange Act to file a statement on Schedule 13D with respect to
such Voting Securities, (v) deposit any Voting Securities in a
voting trust or enter into any voting agreement of arrangement
with respect thereto (other than this Agreement), (vi) seek
representation on the Board (other than as provided in this
Agreement), (vii) make any request to amend or waive any
provision of this Section 10, which request would require public
disclosure under applicable law, rule or regulation,

                            -19-

<PAGE>

(viii) disclose any intent, purpose, plan, arrangement or proposal
inconsistent with the foregoing (including any such intent,
purpose, plan, arrangement or proposal that is conditioned on or
would require the waiver, amendment, nullification or
invalidation of any of the foregoing) or take any action that
would require public disclosure of any such intent, purpose,
plan, arrangement or proposal, (ix) take any action challenging
the validity or enforceability of the foregoing or (x) assist,
advise, encourage or negotiate with any Person with respect to,
or seek to do, any of the foregoing.

             (b)     Nothing in this Section 10 shall (i) prohibit or
restrict the Purchaser from responding to any inquiries from any
stockholders of the Company as to the Purchaser's intention with
respect to the voting of any Voting Securities Beneficially Owned
by the Purchaser so long as such response is consistent with the
terms of this Agreement; (ii) restrict the right of Purchaser's
Designee to vote on any matter as such individual believes
appropriate in light of his or her duties as a director or
committee member or restrict the manner in which Purchaser's
Designee may participate in his or her capacity as a director in
deliberations or discussions at meetings of the Board or as a
member of any committee thereof; (iii) prohibit Purchaser from
Beneficially Owning Voting Securities issued as dividends or
distributions in respect of, or issued upon conversion, exchange
or exercise of, securities which the Purchaser is permitted to
Beneficially Own under this Section 10; (iv) prohibit any
officer, director, employee or agent of the Purchaser from
purchasing or otherwise acquiring Voting Securities so long as he
or she is not a member of a Group that includes the Purchaser or
is not otherwise acting on behalf of Purchaser or (v) prohibit
Purchaser from compliance with law, including any Commission
rules or regulations.

             (c)     Notwithstanding anything to the contrary set
forth in this Section 10, if, at any time following the
consummation of a bankruptcy proceeding involving the Company,
any Person (other than the Company) is permitted by law or the
bankruptcy court in which the proceeding is pending to propose a
plan of reorganization for the Company, the Purchaser shall be
permitted to propose a plan of reorganization for the Company;
provided, that no plan of reorganization shall be proposed by the
Purchaser prior to the expiration or termination of the
exclusivity period for the Company's filing of a plan of
reorganization, as such exclusivity period may be extended from
time to time (it being understood and agreed that the Purchaser
shall not object to any extension of the Company's exclusivity
period and shall not initiate or otherwise support any proceeding
to terminate or shorten the length of the Company's exclusivity
period).

     SECTION 11.  Indemnification.

     11.1.   General Indemnification.  The Company shall indemnify,
defend and hold Purchaser and each of its respective officers,
directors, partners, managing directors, Affiliates, employees,
agents, consultants, representatives, successors and assigns
(each a "Purchaser Indemnitee") harmless from and against all
Losses incurred or suffered by a Purchaser Indemnitee arising out
of, relating to or resulting from (i) any breach of any of the
representations or warranties made by the Company in this
Agreement or in any certificate or other instrument delivered
pursuant hereto including, without limitation, the Transaction
Documents, and (ii) any breach of any of the covenants or
agreements made

                            -20-

<PAGE>

by the Company in this Agreement or in any certificate or other
instrument delivered pursuant hereto including, without limitation,
the Transaction Documents.  Purchaser shall indemnify, defend and
hold the Company, its Affiliates, and each of their respective
officers, directors, employees, agents, consultants,
representatives, successors and assigns harmless against all
Losses arising from the breach of any of the covenants or
agreements of the Purchaser in this Agreement or in any certificate
or other instrument delivered pursuant hereto including, without
limitation, the Transaction Documents. Notwithstanding anything to
the contrary in this Agreement, (a) any and all payments by the
Company pursuant to this Section 11 with respect to breach of
representations or warranties shall be limited to, in the aggregate,
an amount equal to the aggregate principal amount of the Notes when
issued (the "Cap"), which Cap shall be reduced by and to the extent
that the Second Note and Third Note are redeemed or paid (other than
by way of conversion), and no indemnification payment by the Company
with respect to any such Losses otherwise payable hereunder shall
be payable until such time as all such Losses (exclusive of
attorneys' fees or other expenses of investigation or defense)
shall aggregate to more than $250,000, and then only to the
extent that such Losses, in the aggregate, exceed such amount;
provided that neither of the foregoing limitations on indemnity
shall apply to or count Losses arising with respect to (A) the
breaches of the representations and warranties in Section 3.11 as
they relate to Taxes or to (B) the matters set forth in Section
11.4; and (b) the Company shall not be liable for any Losses
incurred by the Purchaser as a result of a breach of the
representation and warranty set forth in the last two sentences
of Section 3.3, to the extent that such Losses are eliminated as
a result of a purchase price adjustment pursuant to Section 2.4.
In determining whether a Purchaser Indemnitee is entitled to
recover under this Section 11 for any Losses, the representations
and warranties of the Company shall not be deemed qualified by
any references to materiality contained therein and any breaches
thereof shall be determined without regard to whether such breach
constitutes a Material Adverse Effect or Material Adverse Change.

     11.2.   Indemnification Principles.  For purposes of this
Agreement, "Losses" shall mean each and all of the following
items: claims, losses (excluding losses of earnings or similar
consequential or indirect losses), liabilities, obligations,
payments, damages (excluding indirect or similar damages),
charges, judgments, fines, penalties, amounts paid in settlement,
costs and expenses (including, without limitation, interest which
may be imposed in connection therewith, reasonable costs and
expenses of investigation, actions, suits, proceedings, demands,
assessments and reasonable fees, expenses and disbursements of
counsel, consultants and other experts); provided, however, that
for purposes of calculating Losses pursuant to this Section 11,
Losses of the Company shall be calculated net of any reduction to
the Tax liability of the Company actually realized as a result of
any such item giving rise to a Tax deduction to the Company. Any
indemnification payment by the Company to any Purchaser
Indemnitee pursuant to this Section 11 shall include an
additional amount so that the Purchaser Indemnitee does not,
directly or indirectly, bear any portion of such payment made by
the Company with respect to such payment on account of the
Purchaser Indemnitee's direct or indirect investment in the
Company. To the extent permitted by law, any payment by the
Company to Purchaser pursuant to this Section 11 shall be treated
for all income Tax

                            -21-

<PAGE>

purposes as an adjustment to the price paid by the Purchaser for
the TATRA Shares and Company Shares pursuant to this Agreement.

     11.3.   Claim Notice.  Any claim for indemnification pursuant
to this Section 11 must be made before the expiration of the
survival periods set forth in Section 8 of this Agreement. No
party shall be entitled to indemnification against a Loss arising
from the breach of any representations or warranties of any other
party unless the party seeking indemnification shall have given
to the party from whom indemnification is being sought a claim
notice relating to such Loss (a "Claim Notice") prior to
expiration of the representation or warranty upon which the claim
is based. The Claim Notice shall be given reasonably promptly
(but, in the case of a third party claim against the indemnified
party, within 15 days after the indemnified party has received
written notification of such claim) after the party seeking
indemnity becomes aware of the facts indicating that a claim for
indemnification may be warranted. Each Claim Notice shall specify
in reasonable detail (to the extent known) the nature of the
claim, the applicable provision(s) of this Agreement or other
instrument under which the claim for indemnity arises, and, if
possible, the amount or the estimated amount thereof. The failure
of any indemnified party to give a Claim Notice shall not relieve
the indemnifying party of its obligations under this Section 11,
except to the extent that the indemnified or indemnifying party
is actually materially prejudiced by failure to give such Claim
Notice. The indemnifying party may, through counsel of its own
choosing and reasonably satisfactory to the indemnified party,
assume the defense thereof or other indemnification obligation
with respect thereto; provided, however, that (a) any indemnified
party shall be entitled to participate in any such claim with
counsel of its own choice but at its own expense and (b) any
indemnified party shall be entitled to participate in any such
claim with counsel of its own choice at the expense of the
indemnifying party if representation of both parties by the same
counsel is otherwise inappropriate under applicable standards of
professional conduct or the indemnified party is otherwise
adversely affected thereby. In any event, if the indemnifying
party fails to take reasonable steps necessary to defend
diligently the action or proceeding within 20 days after
receiving the notice from such indemnified party that the
indemnifying party has failed to do so, the indemnified party may
assume such defense or other indemnification obligation and the
fees and expenses of its attorneys will be covered by the
indemnity provided for in this Section 11. Notwithstanding
anything in this Section 11 to the contrary, the indemnifying
party shall not, without the written consent of the indemnified
party, settle or compromise any pending or threatened action or
claim in respect of which indemnification or contribution may be
sought hereunder (whether or not the indemnified party is an
actual or potential party to such action or claim) or consent to
the entry of any judgment (1) which does not, to the extent that
an indemnified party may have any liability with respect to such
action or claim, include as an unconditional term thereof the
delivery by the claimant or plaintiff to the indemnified party of
