                      AGREEMENT AND PLAN OF REORGANIZATION


     AGREEMENT AND PLAN OF REORGANIZATION, dated as of September 30, 1999 (this
"Agreement"), by and among TSI International Software Ltd., a Delaware
corporation ("Parent"); Natchez Acquisition Corp., a Delaware corporation and a
wholly-owned subsidiary of Parent ("Merger Sub"); and Novera Software, Inc., a
Delaware corporation ("Natchez ").

   Intending to be legally bound, and in consideration of the mutual
representations, warranties, covenants and agreements contained herein, Parent,
Merger Sub and Natchez agree as follows:


                                   ARTICLE I

                                   THE MERGER


    1.1  The Merger.  Subject to the terms and conditions hereof, and in
accordance with the Delaware General Corporation Law (the "DGCL"), Merger Sub
will be merged with and into Natchez (the "Merger").  A Certificate of Merger
and any other required documents (collectively, the "Merger Documents"),
substantially in the form attached as Exhibit 1.1, will be duly prepared,
executed and acknowledged by Natchez and Merger Sub and thereafter delivered to
the Secretary of State of Delaware for filing in accordance with the DGCL
contemporaneously with the Closing (as defined in Section 1.3).  The Merger will
become effective at such time as the Merger Documents have been filed with the
Secretary of State of Delaware (the "Effective Time"). Following the Merger,
Natchez will continue as the surviving corporation of the Merger (the "Surviving
Corporation") under the laws of the State of Delaware, and the separate
corporate existence of Merger Sub will cease.

   1.2 Effects of the Merger.  At and after the Effective Time, (i) the Merger
will have all of  the effects provided by the Certificate of Merger and
applicable law, (ii) the Certificate of Incorporation of Natchez will be amended
in the form attached as Appendix A to Exhibit 1.1 until duly further amended,
(iii) the bylaws of Merger Sub will be the bylaws of the Surviving Corporation
until duly amended, (iv) the directors of Merger Sub will be the directors of
the Surviving Corporation, to hold office in accordance with the bylaws of the
Surviving Corporation, (v) the officers of Merger Sub will be the officers of
the Surviving Corporation, to hold office in accordance with the bylaws of the
Surviving Corporation and (vi) the issued and outstanding certificates for the
capital stock of Merger Sub will be the issued and outstanding certificates
initially representing all of the issued capital stock of the Surviving
Corporation. The Merger is intended to be a reorganization within the meaning of
Section 368(a)(1)(A) of the Internal Revenue Code of 1986, as amended (the
"Code"), and this Agreement is intended to constitute a "plan of reorganization"
within the meaning of the regulations promulgated under Section 368 of the Code.

   1.3 Closing.  The closing of the transactions contemplated by this Agreement
(the "Closing") will take place on the date of this Agreement or as soon as
practicable (but no more than three (3) business days) after satisfaction or
waiver of the last to be fulfilled of the conditions set forth in Article VIII
that by their terms are not to occur at the Closing (the "Closing Date"), but in
no event later than October 31, 1999, at the offices of Testa, Hurwitz &
Thibeault, LLP, 125 High Street,
<PAGE>

Boston, Massachusetts, unless another date or place is agreed to in writing by
Parent and Natchez. If all of conditions set forth in Article VIII hereof are
determined to be satisfied (or duly waived) at the Closing, concurrently with
the Closing the parties hereto will cause the Merger to be consummated by the
filing of the Merger Documents with the Secretary of State of Delaware. The
Closing will be deemed to have concluded at the Effective Time.

   1.4 Approval by the Stockholders of Natchez.  Natchez will take all action
necessary in accordance with applicable law, its Charter Documents (as defined
below) and any agreements to which it is a party to solicit the approval of this
Agreement, the Merger and all of the transactions contemplated hereby by all
stockholders of Natchez by means of a written consent of stockholders in
accordance with the DGCL, or if it is unable to obtain such written consent, by
a duly convened meeting of stockholders. Natchez will use its reasonable best
efforts to obtain such stockholder approval.  Natchez represents and warrants
that its Board of Directors has duly (i) approved the Merger in accordance with
the DGCL and (ii) resolved to recommend to the stockholders of Natchez that they
approve this Agreement, the Merger and all of the transactions contemplated
hereby.

<PAGE>

exercisability resulting from the consummation of the Merger), the number of
shares of Parent Common Stock determined by multiplying the number of shares of
Natchez Common Stock subject to such Option in accordance with its terms
immediately prior to the Effective Time by the Common Conversion Ratio (rounded
down to the nearest whole share), at an exercise or conversion price per share
of Parent Common Stock (rounded up to the nearest whole cent) determined by
dividing the exercise price per share of Natchez Common Stock of such Option
immediately prior to the Effective Time by the Common Conversion Ratio. It is
the intention of the parties that the Options assumed by Parent qualify
following the Effective Time as Incentive Stock Options as defined in Section
422 of the Code to the extent such Options qualified as Incentive Stock Options
immediately prior to the Effective Time.

          (b)  As soon as practicable after the Effective Time, Parent or the
Surviving Corporation shall deliver to the holders of Options assumed in
accordance with this Section 2.3 appropriate notices setting forth such holders'
rights pursuant to such Options, as amended by this Section 2.3, and the
agreements evidencing such Options shall continue in effect on the same terms
and conditions (subject to any acceleration of vesting or exercisability
resulting from the consummation of the Merger).

          (c)  The Parent shall take all corporate action necessary to reserve
for issuance a sufficient number of shares of Parent Common Stock for delivery
upon exercise of the Options assumed in accordance with this Section 2.3.  As
soon as practicable after the Effective Time and in any event within fourteen
(14) days thereof, the Parent will file a Registration Statement on Form S-8 (or
any successor form) under the Securities Act of 1933, as amended (the
"Securities Act"), with respect to all shares of Parent Common Stock subject to
such Options that may be registered on a Form S-8.

          (d)  At the Effective Time, by virtue of the Merger and without any
action on the part of any holder, all conditions, including vesting, as were
applicable with respect to shares of restricted stock issued to employees of
Natchez at the Effective Time, shall remain in effect on substantially the same
terms and conditions (subject to any acceleration of vesting resulting from the
consummation of the Merger).

   2.4 Dissenting Shares.

          (a)  For purposes of this Agreement, "Dissenting Shares" means shares
of Natchez Stock held as of the Effective Time by a Natchez Stockholder who has
not voted such shares of Natchez Stock in favor of the adoption of this
Agreement and the Merger and with respect to which appraisal shall have been
duly demanded and perfected in accordance with Section 262 of the DGCL and not
effectively withdrawn or forfeited prior to the Effective Time.
Notwithstanding Section 2.1 hereof, Dissenting Shares shall not be converted
into or represent the right to receive shares of Parent Common Stock, unless
such Natchez Stockholder shall have forfeited his or her right to appraisal
under the DGCL or properly withdrawn his, her or its demand for appraisal.  If
such Natchez Stockholder has so forfeited or withdrawn his, her or its right to
appraisal of Dissenting Shares, then (i) as of the occurrence of such event,
such holder's Dissenting Shares shall cease to be Dissenting Shares and shall be
converted into and represent the right to receive  shares of Parent Common Stock
issuable in respect of such Natchez Stock pursuant to Section 2.1, and (ii)
promptly following the occurrence of such event, Parent shall deliver to such
Natchez Stockholder a certificate representing 90% of the shares of Parent
Common Stock to which such holder is entitled pursuant to Section 2.1 (which
shares


                                     - 5 -
<PAGE>

shall be considered Initial Shares for purposes of this Agreement) and shall
deliver to the Escrow Agent a certificate representing the remaining 10% of
shares of Parent Common Stock to which such holder is entitled pursuant to
Section 2.1 (none of which Shares of Parent Common Stock shall be unvested
subject to any right of repurchase risk of forfeiture or other condition in
favor of the Surviving Corporation or Parent) (which shares shall be considered
Escrow Shares for all purposes of this Agreement).

          (b)  Natchez shall give Parent (i) prompt notice of any written
demands for appraisal of any Natchez Stock, withdrawals of such demands, and any
other instruments that relate to such demands received by Natchez and (ii) the
opportunity to direct all negotiations and proceedings with respect to demands
for appraisal under the DGCL.  Natchez shall not, except with the prior written
consent of Parent, make any payment with respect to any demands for appraisal of
Natchez Stock or offer to settle or settle any such demands.

       2.5  Surrender of Certificates.

          (a)  Exchange Agent.  Prior to the Effective Time, Parent shall
designate The Bank of New York to act as exchange agent (the "Exchange Agent")
in the Merger.

          (b)  Parent to Provide Parent Common Stock.  At or promptly after the
Effective Time, Parent shall deliver to the Exchange Agent for exchange in
accordance with this Article II, (i) one or more certificates representing the
Initial Shares issuable pursuant to Section 2.1 in exchange for shares of
Natchez Stock outstanding at the Effective Time, provided, however, that, on
behalf of the Natchez Stockholders, and pursuant to Section 2.2 and the Escrow
Agreement, Parent shall deposit into an escrow account and deliver to the Escrow
Agent one or more certificates representing the Escrow Shares, and (ii) any cash
in respect of fractional shares as provided in Section 2.7.

          (c)  Exchange Procedures.  At or promptly after the Effective Time,
the Surviving Corporation shall cause to be mailed to each holder of record of a
certificate or certificates (the "Certificates") which immediately prior to the
Effective Time represented outstanding shares of Natchez Stock whose shares were
converted into the right to receive shares of Parent Common Stock pursuant to
Section 2.1, (i) a letter of transmittal (which shall specify that delivery
shall be effected, and risk of loss and title to the Certificates shall pass,
only upon delivery of the Certificates to the Exchange Agent, and shall be in
such form and have such other provisions as Parent may reasonably specify), (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for certificates representing shares of Parent Common Stock, and (iii) an
Investment Agreement (as defined herein) to be executed by such holder, if not
previously delivered to Parent by such holder.  Upon surrender of a Certificate
for cancellation to the Exchange Agent or to such other agent or agents as may
be appointed by Parent, together with such letter of transmittal and such
Investment Agreement, duly completed and validly executed in accordance with the
instructions thereto, the holder of such Certificate shall be entitled to
receive in exchange therefor a certificate representing the number of whole
shares of Parent Common Stock (less the number of Escrow Shares to be deposited
with the Escrow Agent on such holder's behalf pursuant to Section 2.2 and the
Escrow Agreement), plus cash, if any, in lieu of fractional shares in accordance
with Section 2.7, to which such holder is entitled pursuant to Section 2.7, and
the Certificate so surrendered shall forthwith be cancelled.  Until so
surrendered, and subject to Section 2.4, each outstanding Certificate that,
prior to the Effective Time, represented shares of Natchez Stock will be deemed
from and after the Effective Time, for all



                                     - 6 -
<PAGE>

corporate purposes, other than the payment of dividends, to evidence the
ownership of the number of full shares of Parent Common Stock into which such
shares of Natchez Stock shall have been so converted and the right to receive an
amount in cash in lieu of the issuance of any fractional shares in accordance
with Section 2.7.


       (d)  Lost, Stolen or Destroyed Certificates.  In the event any
certificates evidencing shares of Natchez Stock shall have been lost, stolen or
destroyed, the Exchange Agent shall issue in exchange for such lost, stolen or
destroyed certificates, upon the making of an affidavit of that fact by the
holder thereof, such shares of Parent Common Stock and cash for fractional
shares, if any, as may be required pursuant to Section 2.7; provided, however,
that Parent may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed certificates to
deliver a bond in such sum as it may reasonably direct as indemnity against any
claim that may be made against Parent or the Exchange Agent with respect to the
certificates alleged to have been lost, stolen or destroyed.

          (e)  Distributions With Respect to Unexchanged Shares.  No dividends
or other distributions declared or made after the Effective Time with respect to
Parent Common Stock with a record date after the Effective Time will be paid to
the holder of any unsurrendered Certificate with respect to the shares of Parent
Common Stock represented thereby until the holder of record of such Certificate
shall surrender such Certificate.  Subject to applicable law, following
surrender of any such Certificate, there shall be paid to the record holder of
the certificates representing whole shares of Parent Common Stock issued in
exchange therefor, without interest, at the time of such surrender, the amount
of dividends or other distributions with a record date after the Effective Time
theretofore paid with respect to such whole shares of Parent Common Stock.

          (f)  Transfers of Ownership.  If any certificate for shares of Parent
Common Stock is to be issued in a name other than that in which the certificate
surrendered in exchange therefor is registered, it will be a condition of the
issuance thereof that the certificate so surrendered will be properly endorsed
and otherwise in proper form for transfer and that the person requesting such
exchange will have paid to Parent or any agent designated by it any transfer or
other taxes required by reason of the issuance of a certificate for shares of
Parent Common Stock in any name other than that of the registered holder of the
certificate surrendered, or established to the satisfaction of Parent or any
agent designated by it that such tax has been paid or is not payable.

          (g)  No Liability.  Notwithstanding anything to the contrary in this
Section 2.5, none of the Exchange Agent, the Surviving Corporation or any party
hereto shall be liable to a holder of shares of Parent Common Stock or Natchez
Stock for any amount properly paid to a public official pursuant to any
applicable abandoned property, escheat or similar law.


   2.6   No Further Ownership Rights in Natchez Common Stock.  At the Effective
Time, each Holder of a Certificate shall cease to have any rights as a
Stockholder of Natchez except such rights, if any, as such Holder may have with
respect to Dissenting Shares.  The Merger and its approval by the Natchez
Stockholders and the execution of this Agreement will be deemed, at the
Effective Time,  to constitute full satisfaction and termination of all rights
and agreements pertaining to Natchez Stock pursuant to the DGCL, by contract or
otherwise.  After the Effective Time, there will be no transfers on the stock
transfer books of Natchez of Natchez Stock.  If, after the Effective Time,
Certificates are



                                     - 7 -
<PAGE>

presented to the Surviving Corporation for any reason, they shall be cancelled
and exchanged as provided in this Article II.

   2.7 No Fractional Shares.  No certificates or scrip for fractional shares of
Parent Common Stock will be issued, no Parent stock split or dividend will be
paid in respect of any fractional share interest, and no such fractional share
interest will entitle the owner thereof to vote or to any rights of or as a
stockholder of Parent.  In lieu of such fractional shares, any holder of shares
of Natchez Stock who would otherwise be entitled to a fraction of a share of
Parent Common Stock (after aggregating all fractional shares of Parent Common
Stock to be received by such holder) will be paid the cash value of such
fraction, which will be equal to such fraction multiplied by the Parent Average
Closing Price.

liens for Taxes or similar liens arising in the ordinary course of business and
not yet due ("Liens"); and there are no outstanding subscriptions, warrants,
options, convertible securities, or other rights (contingent or other) pursuant
to which any of the Subsidiaries is or may become obligated to issue any shares
of its capital stock to any Person other than Natchez or one of the other
Subsidiaries.

each of this Agreement and such other agreements constitutes a valid, binding
and enforceable obligation of Natchez in accordance with its terms, except to
the extent that enforceability thereof may be limited by applicable bankruptcy,
insolvency, reorganization or similar laws affecting the enforcement of
creditors' rights generally and by principles of equity regarding the
availability of remedies.

     3.4  Compliance with Laws and Other Instruments; Non-Contravention.
Natchez holds, and at all times has held, all licenses, permits and
authorizations from all Governmental Entities (as defined below) necessary for
the lawful conduct of its business pursuant to all applicable statutes, laws,
ordinances, rules and regulations of all such Governmental Entities having

Natchez, claimed violations of any such license, permit or authorization or any
such statute, law, ordinance, rule or regulation where such violations would
have a Material Adverse Effect on the Business Condition of Natchez. Assuming
the receipt of all Consents (as defined below) and except as in the aggregate
would not have a Material Adverse Effect on the Business Condition of Natchez,
neither the execution, delivery or performance of this Agreement and all other
agreements contemplated hereby by Natchez, nor the consummation of the Merger or
any other transaction described herein, does or will, after the giving of
notice, or the lapse of time, or otherwise, conflict with, result in a breach
of, or constitute a default under, the Charter Documents of Natchez or any
federal, foreign, state or local court or administrative order or process,
statute, law, ordinance, rule or regulation, or any contract, agreement or
commitment to which Natchez is a party, or under which Natchez is obligated, or
by which Natchez or any of the rights, properties or assets of Natchez are
subject or bound; result in the creation of any Lien upon, or otherwise
adversely affect, any of the rights, properties or assets of Natchez; terminate,
amend or modify, or give any party the right to terminate, amend, modify,
abandon or refuse to perform or comply with, any contract, agreement or
commitment to which Natchez is a party, or under which Natchez is obligated, or
by which Natchez or any of the rights, properties or assets of Natchez are
subject or bound; or accelerate, postpone or modify, or give any party the right
to accelerate, postpone or modify, the time within which, or the terms and
conditions under which, any liabilities, duties or obligations are to be
satisfied or performed, or any rights or benefits are to be received, under any
contract, agreement or commitment to which Natchez is a party, or under which
Natchez may be obligated, or by which Natchez or any of the rights, properties
or assets of Natchez are subject or bound. Section 3.4 of the Natchez Disclosure
Schedule sets forth each agreement, contract or other instrument binding upon
Natchez requiring a notice or consent (by its terms or as a result of any

delivery or performance of this Agreement and all other agreements contemplated
hereby by Natchez or the consummation of the Merger or any other transaction
described herein, except for the filing by Natchez and Merger Sub of the

          (f)  Section 3.5 of the Natchez Disclosure Schedule separately lists
all parties (other than employees) who have created any portion of, or otherwise
have any rights in or to, Natchez Intellectual Property.  Natchez has secured
from all parties who have created any portion of, or otherwise have any rights
in or to, Natchez Intellectual Property valid and enforceable written
assignments of any such work or other rights to Natchez and has provided true
and complete copies of such assignments to Parent.

          (g)  Natchez has obtained written agreements from all employees and
from third parties with whom Natchez, to its knowledge, has shared confidential
proprietary information (i) of Natchez or (ii) received from others that Natchez
is obligated to treat as confidential and to obtain the written agreement of
employees and others to keep confidential, which agreements require such
employees and third parties to keep such information confidential in accordance
with the terms thereof.  Natchez has made available a copy of the form of such
written agreement with employees, as executed, to Parent together with copies of
all non-standard agreements with employees.

     3.6  Financial Statements.

          (a)  Natchez has delivered to Parent an unaudited balance sheet (the
"Unaudited Balance Sheet") as of August 31, 1999 (the "Unaudited Balance Sheet
Date") and audited balance sheets (the "Audited Balance Sheets") as of December
31, 1998 (the "Audited Balance Sheet Date") and December 31, 1997, unaudited
statements of income and cash flows for the eight-month period ended August 31,
1999 and audited statements of income and cash flows for its fiscal years ended
December 31, 1998 and December 31, 1997 (all of such balance sheets and
statements of income and cash flows are collectively referred to as the
"Financial Statements"). The Financial Statements: (i) are in accordance with
the books and records of Natchez; (ii) present fairly, in all material respects,
the financial position of Natchez as of the date indicated and the results of
its operations and cash flows for such periods; and (iii) have been prepared in
accordance with generally accepted accounting principles ("GAAP") consistently
applied (subject, in the case of unaudited statements, to the absence of
footnote disclosure and in the case of unaudited interim statements to year-end
adjustments, which will not be material either individually or in the
aggregate).  As of the Unaudited Balance Sheet Date, there were no material
liabilities, claims or obligations of any nature, whether accrued, absolute,
contingent,



                                     - 13 -
<PAGE>

anticipated or otherwise, whether due or to become due, that are not shown or
provided for either in the Unaudited Balance Sheet or Section 3.6 of the Natchez
Disclosure Schedule, and since the Unaudited Balance Sheet Date, Natchez has
incurred no liabilities, claims or obligations of any nature, whether accrued,
absolute, contingent, anticipated or otherwise, other than in either case in the
ordinary course of business and except for (x) liabilities incurred by Natchez
not required by GAAP to be reflected thereon or (y) liabilities incurred in
connection with the preparation and execution of this Agreement and the
consummation of the transactions contemplated herein (which liabilities are
estimated and have been disclosed on Section 3.6 of the Natchez Disclosure
Schedule).

          (b)  All of the accounts, notes and other receivables which are
reflected in the Unaudited Balance Sheet were acquired in the ordinary course of
business; and, except to the extent reserved against in the Unaudited Balance
Sheet, all of the accounts, notes and other receivables which are reflected
therein have been collected in full, or are good and collectible, in the
ordinary course of business; and all of the accounts, notes and other
receivables which have been acquired by Natchez since the Unaudited Balance
Sheet Date were acquired in the ordinary course of business and have been
collected in full, or are good and collectible, subject to an appropriate
reserve determined in a manner consistent with past practices of Natchez, in the
ordinary course of business.  No accounts, notes or other receivables are
contingent upon the performance by Natchez of any obligation or contract.  No
Person has any Lien on any of such receivables and no agreement for deduction or
discount has been made with respect thereto.

          3.7  Taxes.

          (a)  The term "Taxes" as used herein means all federal, state, local
and foreign income taxes, alternative or add-on minimum taxes, estimated, gross
income, gross receipts, sales, use, ad valorem, value added, transfer,
franchise, capital, profits, lease, service, license, withholding, payroll,
employment, excise, severance, stamp, occupation, premium, property,
environmental or windfall profit taxes, customs duties and other taxes,
governmental fees and other like assessments and charges of any kind whatsoever,
together with all interest, penalties, additions to tax and additional amounts
with respect thereto, and the term "Tax" means any one of the foregoing Taxes.
The term "Tax Returns" as used herein means all returns, declarations, reports,
claims for refund, information statements and other documents relating to Taxes,
including all schedules and attachments thereto, and including all amendments
thereof, and the term "Tax Return" means any one of the foregoing Tax Returns.

          (b)  Natchez has timely filed all Tax Returns required to be filed and
has timely paid all Taxes owed (whether or not shown as due on such Tax
Returns), including, without limitation, all Taxes which Natchez is obligated to
withhold for amounts owing to employees, creditors and third parties.  All Tax
Returns filed by Natchez were complete and correct in all material respects, and
such Tax Returns correctly reflected the material facts regarding the income,
business, assets, operations, activities, status and other matters of Natchez
and any other information required to be shown thereon.  None of the Tax Returns
filed by Natchez or Taxes payable by Natchez have been the subject of an audit,
action, suit, proceeding, claim, examination, deficiency or assessment by any
Governmental Entity, and no such audit, action, suit, proceeding, claim,
examination, deficiency or assessment is currently pending or, to the knowledge
of Natchez, threatened.  Natchez is not currently the beneficiary of any
extension of time within which to file any Tax Return, and Natchez has not
waived any statute of limitation with respect to any Tax or agreed to any
extension of time with respect to a Tax



                                     - 14 -
<PAGE>

assessment or deficiency. None of the Tax Returns filed by Natchez contains a
disclosure statement under former Section 6661 of the Code or Section 6662 of
the Code (or any similar provision of state, local or foreign Tax law). Natchez
is not a party to any Tax sharing agreement or similar arrangement. Natchez has
never been a member of a group filing a consolidated federal income Tax Return
or a consolidated, combined or other affiliated group for state, local or other
Tax purposes (other than a group the common parent of which was Natchez), and
Natchez does not have any liability for the Taxes of any Person (other than
Natchez) under Treasury Regulation Section 1.1502-6 (or any corresponding
provision of state, local or foreign Tax law), as a transferee or successor, by
contract, or otherwise.

          (c)  Natchez is not a party to any agreement, contract, arrangement or
plan that has resulted or would result, separately or in the aggregate, in the
payment of (i) any "excess parachute payments" within the meaning of Section
280G of the Code (without regard to the exceptions set forth in Sections
280G(b)(4) and 280G(b)(5) of the Code) or (ii) any amount for which a deduction
would be disallowed or deferred under Section 162 or Section 404 of the Code.
Natchez has not agreed to make any adjustment under Section 481(a) of the Code
(or any corresponding provision of state, local or foreign law) by reason of a
change in accounting method or otherwise, and Natchez will not be required to
make any such adjustment as a result of the transactions set forth in this
Agreement.  Natchez does not have and has not had a permanent establishment in
any foreign country, as defined in any applicable Tax treaty or convention
between the United States and such foreign country.  None of the assets of
Natchez is property which is required to be treated as being owned by any other
Person pursuant to the so-called "safe harbor lease" provisions of former
Section 168(f)(8) of the Code.  None of the assets of Natchez directly or
indirectly secures any debt, the interest on which is tax exempt under Section
103(a) of the Code.  None of the assets of Natchez is "tax-exempt use property"
within the meaning of Section 168(h) of the Code.  No claim has ever been made
by any Governmental Entity in a jurisdiction where Natchez does not file Tax
Returns that it is or may be subject to Tax in that jurisdiction.  Natchez has
not taken any action that would have the effect of deferring any material
liability for Taxes of Natchez from any taxable period ending at or before the
Effective Time to any taxable period thereafter.  Natchez has never filed a
consent pursuant to Section 341(f) of the Code (or any corresponding provision
of state, local or foreign law), relating to collapsible corporations, or agreed
to have Section 341(f)(2) of the Code (or any corresponding provision of state,
local or foreign law) apply to the disposition of any asset owned by it.  No
power of attorney has been granted by Natchez, and is currently in force, with
respect to any matter relating to Taxes.  Natchez has not participated in an
international boycott as defined in Section 999 of the Code.  Except as set
forth in Section 3.7 of the Natchez Disclosure Schedule, none of the shares of
outstanding capital stock of Natchez are subject to a "substantial risk of
forfeiture" within the meaning of Section 83 of the Code.

          (d)  There are no liens for Taxes (other than for Taxes not yet due
and payable) upon the assets of Natchez.  The unpaid Taxes of Natchez did not,
as of the Unaudited Balance Sheet Date, exceed the reserve for actual Taxes (as
opposed to any reserve for deferred Taxes established to reflect timing
differences between book and Tax income) as shown on the Unaudited Balance
Sheet, and will not exceed such reserve as adjusted for the passage of time
through the Closing Date in accordance with the past custom and practice of
Natchez in filing their Tax Returns (taking into account any Taxes incurred as a
result of the transactions contemplated by this Agreement).  Natchez has not
incurred and will not incur any liability for Taxes subsequent to the Unaudited
Balance Sheet Date through the Closing Date except in the ordinary course of
business.  Natchez is not a party to any joint venture,



                                     - 15 -
<PAGE>

partnership, limited liability company or other arrangement or contract which
could be treated as a partnership for federal income tax purposes.

directors, or any "affiliate" or "associate" (as such terms are defined in the
rules and regulations promulgated under the Securities Act of any such Person,
has any direct or indirect ownership interests, except for payments or
liabilities with respect to advances for all travel expenses to employees in the
ordinary course of business; or

          (q) Any agreement undertaking or commitment to do any of the
foregoing.

          3.9  Leases in Effect; Real Property.  (a)  All real property leases
and subleases as to which Natchez is a party and any amendments or modifications
thereof are listed in Section 3.9 of the Natchez Disclosure Schedule (each a
"Lease" and collectively, the "Leases") are valid, in full force and effect and
enforceable, and there are no existing defaults on the part of Natchez, and
Natchez has not received or given notice of default or claimed default with
respect to any Lease, nor is there any event that with notice or lapse of time,
or both, would constitute a default on the part of Natchez thereunder.  Natchez

          (b) To the knowledge of Natchez, the improvements located on the real

an officer, director, or employee thereof (and compensation by Natchez in
consideration of such services) and (b) relationships with Natchez as
stockholders or option holders therein, none of the directors, officers, or

failure to act which has or



                                     - 19 -
<PAGE>

might cause any such contract to be canceled or terminated. All known claims for
insurance have been presented.

     3.17  Employees.  The Natchez Disclosure Schedule sets forth a list of (a)
the names, titles, salaries and all other compensation of all salaried Natchez
employees (such term meaning permanent and temporary, full-time and part-time
employees) and (b) the wage rates for non-salaried Natchez employees (by
classification). Any persons engaged by Natchez as independent contractors,
rather than employees, have been properly classified as such and have been so
engaged in accordance with all applicable federal, foreign, state or local laws.
No employee has stated to any of David Power, Herbert Rush, Bart Hanlon or John
Keenan that such employee intends to resign or retire as a result of the
transactions contemplated by this Agreement or otherwise within six months after
the Closing Date. Hours worked by and payments made to employees of Natchez have
not been in violation of the Fair Labor Standards Act or any other applicable
federal, foreign, state or local laws dealing with such matters.  Natchez is not
and never has been engaged in any dispute or litigation with an employee or
former employee regarding matters pertaining to intellectual property or
assignment of inventions. Natchez has never been and, to the knowledge of
Natchez, is not now subject to a union organizing effort.  Natchez does not have
any written contract of employment or other employment, severance or similar
agreement with any of its employees or any established policy or practice
relating thereto, and all of its employees are employees-at-will.  Natchez is
not a party to any pending, or to Natchez's knowledge, threatened, labor
dispute.  Natchez has complied in all material respects with all applicable
federal, state and local laws, ordinances, rules and regulations and
requirements relating to the employment of labor, including but not limited to
the provisions thereof relating to wages, hours, collective bargaining and
ensuring equality of opportunity for employment and advancement of minorities
and women.  There are no claims pending, or, to the knowledge of Natchez,
threatened to be brought, in any court or administrative agency by any former or
current Natchez employees for compensation, pending severance benefits, vacation
time, vacation pay or pension benefits, or any other claim threatened or pending
in any court or administrative agency from any current or former employee or any
other Person arising out of Natchez's status as employer, whether in the form of
claims for employment discrimination, harassment, unfair labor practices,
grievances, wrongful discharge, or otherwise.

     3.18  Employee Benefit Plans.  Each Plan (as defined below) covering
active, former, or retired employees of Natchez is listed in Section 3.18 of the
Natchez Disclosure Schedule.  "Plan" means any employee benefit plan as defined
in Section 3(3) of ERISA (as defined below) and will also include any Code
Section125 flexible benefit plan or arrangement, employment, severance or
similar contract, arrangement or policy and each plan or arrangement providing

sharing, bonuses, phantom stock, stock options, stock appreciation rights or
other forms of incentive compensation or post-retirement insurance, compensation

applicable, any related trust agreement, annuity, or insurance contract, the
most recent IRS determination or opinion letter, copies of test results for the
Code Section 401(k) and 401(m) nondiscrimination requirements and the top heavy
test requirements for the last three years, and any material correspondence with

(Form 5500) required to be filed with the Internal Revenue Service have been
properly filed on a timely basis, and Natchez has provided copies of the three
most recently filed Forms 5500 for each applicable Plan. Any Plan intended to be
qualified under Section 401(a) of the



                                     - 20 -
<PAGE>

Code has been determined by the Internal Revenue Service to be so qualified or
has applied (or has time remaining in which to apply) to the Internal Revenue
Service for such a determination letter prior to the expiration of the requisite
period under applicable Treasury regulations or Internal Revenue Service
pronouncements in which to apply for such a determination letter and to make any
amendments necessary to obtain a favorable determination or has been established
under a standardized prototype plan for which an Internal Revenue Service
opinion letter has been obtained by the plan sponsor and is valid as to the
adopting employer. To the knowledge of Natchez, nothing has occurred which could
reasonably be expected to cause the loss of the tax-qualified status of any Plan
intended to qualify under Section 401(a) of the Code. No operational error has
occurred which would adversely affect the qualified status of the Plan. No Plan
is covered by Title IV of the Employee Retirement Income Security Act of 1974,
as amended ("ERISA"), or Section 412 of the Code. No "prohibited transaction,"
as defined in ERISA Section 406 or Code Section 4975 has occurred with respect
to any Plan unless such a transaction was exempt from such rules. Each Plan has
been maintained and administered in compliance with its terms and with the
requirements prescribed by any and all statutes, orders, rules and regulations,
including but not limited to ERISA and the Code, which are applicable to such
Plans. There are no pending or anticipated claims against or otherwise involving
any of the Plans and no suit, action, or other litigation (excluding claims for
benefits incurred in the ordinary course of Plan activities) has been brought
against or with respect to any Plan. All required contributions to any Plan have
been made. Neither Natchez nor any entity which is considered one employer with
Natchez under Section 414 of the Code or Section 4001 of ERISA has ever
maintained or contributed to or incurred or expects to incur liability with
respect to any Plan subject to Title IV of ERISA or any "multi-employer plan"
within the meaning of Section 4001(a)(3) of ERISA. There are no restrictions on
the rights of Natchez to amend or terminate any Plan without incurring any
liability thereunder other than for benefits accrued through the date of
amendment or termination and reasonable administrative expenses related thereto.
Natchez has not engaged in or is a successor or parent corporation to an entity
that has engaged in a transaction described in ERISA Section 4069. There have
been no amendments to, written interpretation of, or announcement (whether or
not written) by Natchez relating to, or change in employee participation or
coverage under, any Plan. Neither Natchez nor any of its ERISA affiliates have
any current or projected liability in respect of post-employment or post-
retirement welfare benefits for retired or former employees of Natchez other

                                   ARTICLE IX

                                INDEMNIFICATION


     9.1  Indemnification Relating to Agreement.  Subject to Sections 9.4 and
9.6, the stockholders of Natchez, by virtue of their approval of this Agreement
and the Merger in accordance with the applicable provisions of the DGCL, jointly
and severally with respect to all amounts held pursuant to the Escrow Agreement
and severally and not jointly with respect to amounts in excess thereof, hereby
agree to defend, indemnify and hold Parent harmless from and against, and to
reimburse Parent with respect to, any and all losses, damages, liabilities,
claims, judgments, settlements, fines, costs and expenses (including reasonable
attorneys' fees), determined as provided in Section 9.4 ("Indemnifiable
Amounts"), of every nature whatsoever  incurred by Parent (which will be deemed
to include any of the foregoing incurred by the Surviving Corporation) by reason
of or arising out of or in connection with (i) any breach, or any claim
(including claims by parties other than Parent) that constitutes a breach, by
Natchez of any representation or warranty of Natchez contained in this Agreement
or in any certificate or other document delivered to Parent pursuant to this
Agreement, other than any breach or related claim taken or not taken at the
written direction of or after consultation with and written concurrence of
Parent or (ii) the failure, partial or total, of Natchez to perform any
agreement or covenant required by this Agreement to be performed by it other
than any breach or related claim taken or not taken at the written direction of
or after consultation with and written concurrence of Parent.  The foregoing
obligations to indemnify Parent will be determined without regard to any right
to indemnification to which any Person may have in his or her capacity as an
officer, director, employee, agent or any other capacity of Natchez, and no
stockholder of Natchez will be entitled to any indemnification from Natchez or
the Surviving Corporation for amounts paid hereunder.

     9.2  Third Party Claims.  With respect to any claims or demands by third
parties as to which Parent may seek indemnification hereunder, other than claims
or demands covered by Section 9.3, whenever Parent will have received a written
notice that such a claim or demand has been asserted or threatened, Parent will
promptly notify the "Indemnification Representative" (as designated in the
Escrow Agreement) of such claim or demand and of the facts within Parent's
knowledge that relate thereto within a reasonable time after receiving such
written notice; provided, however, no delay on the part of Parent shall relieve
the stockholders of Natchez of any liability or obligation hereunder, except to
the extent that the defense of such claim or demand has been materially
prejudiced by Parent's



                                     - 36 -
<PAGE>

failure to give notice within a reasonable time after receiving notice thereof.
The Indemnification Representative will then have the right to defend, contest,
negotiate or settle any such claim or demand through counsel of his own
selection, reasonably satisfactory to Parent, and solely at the cost and expense
of the stockholders of Natchez, which costs and expenses will be payable out of
the property being held pursuant to the Escrow Agreement; provided, however, if
the Indemnification Representative exercises its right to defend, contest,
negotiate or settle any such claim or demand and there exists an actual conflict
of interest between the interests of the stockholders of Natchez and those of
the Parent with respect to such claim or demand, Parent may retain counsel
satisfactory to it and the reasonable fees and expenses of counsel to Parent
shall be considered Indemnifiable Amounts for purposes of this Agreement.
Notwithstanding the preceding sentence, the Indemnification Representative will
not settle, compromise, or offer to settle or compromise any such claim or
demand without the prior written consent of Parent, which consent will not be
unreasonably withheld. Without limiting Parent's rights to object for other
reasons, Parent may object to a settlement or compromise which includes any
provision which in its reasonable judgment may have an adverse impact on or
establish an adverse precedent for the Business Condition of Parent or any of
its Subsidiaries. If the Indemnification Representative gives notice to Parent
within twenty (20) calendar days after Parent has notified the Indemnification
Representative that any such claim or demand has been made in writing, that the
Indemnification Representative elects to have Parent defend, contest, negotiate,
or settle any such claim or demand, then Parent will have the right to contest
and/or settle any such claim or demand and seek indemnification pursuant to this
Article IX as to any Indemnifiable Amounts; provided, however, that Parent will
not settle, compromise, or offer to settle or compromise any such claim or
demand without the prior written consent (which may include a general or limited
consent) of the Indemnification Representative, which consent will not be
unreasonably withheld. If the Indemnification Representative fails to give
written notice to Parent of his intention to contest or settle any such claim or
demand within twenty (20) calendar days after Parent has notified the
Indemnification Representative that any such claim or demand has been made in
writing, or if any such notice is given but any such claim or demand is not
contested by the Indemnification Representative within a reasonable time
thereafter, Parent will have the right to contest and/or settle any such claim
or demand in its sole discretion and seek indemnification pursuant to this
Article IX as to any Indemnifiable Amounts.

     9.3  Tax Contests. Notwithstanding any of the foregoing, Parent will have
the right to conduct any Tax audit or other Tax contest relating to the
Surviving Corporation. Parent will conduct any such Tax audit or other Tax
contest in good faith.  With respect to any matters relating to such Tax audits
or other Tax contests as to which Parent may seek indemnification hereunder,
Parent shall consult with the Indemnification Representative and allow him to
comment before taking any position or making any written submission with any
Governmental Entity with regard to any indemnifiable matter.

     9.4  Limitations.  Notwithstanding any other provision in this Article IX,
(i) Parent will be entitled to indemnification only to the extent that the
aggregate Indemnifiable Amounts (which shall be determined for all purposes of
this Article IX disregarding any qualification in any representation or warranty
as to "materially" or "material") exceed Two Hundred Fifty Thousand Dollars
($250,000) (the "Threshold Amount"), provided that at such time as the amount to
which Parent is entitled to be indemnified exceeds the Threshold Amount, Parent
shall be entitled to be indemnified for Indemnifiable Amounts in excess of
$100,000 and (ii) the aggregate amount to which Parent will be entitled to be
indemnified under this Article IX shall not exceed the value of the Escrow
Shares, as



                                     - 37 -
<PAGE>

determined in accordance with the Escrow Agreement; provided, however, that the
limitation set forth in clause (ii) above shall not apply to any breach, or any
claim (including claims by parties other than Parent) that constitutes a breach,
by Natchez of any representation or warranty contained in Section 3.5 of this
Agreement of which Parent notifies the Indemnification Representative on or
before April 1, 2000, in which case the aggregate amount to which Parent will be
entitled to be indemnified pursuant to this Article IX will not exceed a dollar
amount equal to the aggregate number of Parent Merger Shares valued at the
Parent Average Closing Price, and the liability of any single stockholder of
Natchez for indemnification obligations for any such breach after the
termination of the Escrow Agreement shall be further limited to such
stockholder's pro rata share of any Indemnifiable Amounts based on the number of
Parent Merger Shares received by such stockholder relative to the aggregate
number of Parent Merger Shares; and provided further, however, that there will
be no limitation on the obligations of any person for Indemnifiable Amounts
arising out of criminal activity or fraud of such person. Any Indemnifiable
Amounts payable by a stockholder of Natchez pursuant to the preceding sentence
will be net of, and in addition to, the stockholder's portion of any portion of
the property held pursuant to the Escrow Agreement that is payable to Parent;
provided, however, that Parent will first seek reimbursement of any
Indemnifiable Amounts pursuant to the provisions of the Escrow Agreement, but
may seek indemnification hereunder with respect to any deficiency in any
Indemnifiable Amounts arising out of criminal activity or fraud not satisfied by
the property held pursuant to the Escrow Agreement after the termination of the
Escrow Agreement.

     9.5  Binding Effect.  The indemnification obligations contained in this
Article IX are an integral part of this Agreement and the Merger in the absence
of which Parent would not have entered into this Agreement.

     9.6  Time Limit. The representations, warranties, covenants and agreements
of Natchez set forth in this Agreement will survive the Closing and the
consummation of the transactions contemplated by this Agreement, but any claims
with respect thereto may be made only on or before the first yearly anniversary
of the date of this Agreement; provided, however, that claims alleging fraud may
be made only on or before the third yearly anniversary of the Closing Date.

     9.7  Updating of Disclosure Schedule.  Natchez will have the right to
update the Natchez Disclosure Schedule from time to time prior to the Closing to
reflect changes to the Natchez Disclosure Schedule; provided that any changes to
the Natchez Disclosure Schedule will have no effect for purposes of determining
whether Parent's closing condition set forth in Section 8.2(a) has been
satisfied, but will have the effect of precluding any indemnity claim pursuant
to Article IX (or any reduction in the Threshold Amount) based on any such
changes which have been disclosed in all material respects.

     9.8  Sole Remedy.  Notwithstanding any other provision in this Agreement to
the contrary, the provisions of this Article IX and the provisions of the Escrow
Agreement will be the sole and exclusive remedy of (and corresponding liability
of any stockholder of Natchez, in such stockholder's capacity as such, to)
Parent, Merger Sub and the Surviving Corporation for any damage, claim, cause of
action or right of any nature arising out of or relating to this Agreement, the
certificates or other documents executed or delivered herewith, or the
transactions contemplated hereby; provided, however, that nothing in this
Agreement or the Escrow Agreement will be deemed to limit any right or remedy
for criminal activity or fraud.

          (b) "Registrable Securities" means for any Resale Holder the number of
shares of Parent Common Stock issued to such Resale Holder pursuant to this
Agreement and the Merger, and for all Resale Holders the sum of the Registrable
Securities held by them; provided, however, that such shares of Parent Common
Stock held by a particular Resale Holder shall cease to be Registrable
Securities at such time as such Resale Holder is able to sell such shares
(including all Registrable Securities held by Affiliates of such Resale Holder,
as defined pursuant to Rule 144 of the Securities Act) in their entirety within
a single 90 day period under Rule 144 of the Securities Act.

     10.2 Resale Holder Registration.

          (a) Parent shall use its reasonable best efforts to cause the

and take all such action as may be required in order to permit Parent to comply

Subsequent Shelf Registration Statement prior to June 1, 2000; and provided,
further, that each Resale



                                     - 39 -
<PAGE>

Holder shall provide all such information and materials and take all such action
as may be required in order to permit Parent to comply with all applicable
requirements of the Securities Act and the Exchange Act and to obtain any
desired acceleration of the effective date of such Subsequent Shelf Registration
Statement, such provision of information and materials to be a condition
precedent to the obligations of Parent pursuant to this Article X to register
the Registrable Securities held by such Resale Holder. Upon the effectiveness of
the Subsequent Shelf Registration Statement, the Parent shall provide a combined
prospectus (within the meaning of Rule 429 of the Rules and Regulations under
the Securities Act) for the Initial Shelf Registration Statement and Subsequent
Shelf Registration Statement to the Resale Holders pursuant to Section 10.2(b).
The offerings made pursuant to such registrations shall not be underwritten.

          (b) Parent shall (i) prepare and file with the Commission the
registration statements in accordance with Section 10.2 hereof with respect to
the Registrable Securities and shall use its reasonable best efforts to cause
such registration statements to become effective by April 1, 2000 for the
Initial Shelf Registration Statement and by June 1, 2000 for the Subsequent
Shelf Registration Statement and to keep such registration statements effective
until the sooner to occur of (A) the date on which all Registrable Securities
included within such registration statements have been sold or (B) the first
date following the first anniversary of the Effective Time as to which no
Registrable Securities exist as a result of the proviso to Section 10.1(b) or
(C) the second anniversary of the Effective Time; (ii) prepare and file with the
Commission such amendments to such registration statements and amendments or
supplements to the prospectuses used in connection therewith as may be necessary
to comply with the provisions of the Securities Act with respect to the sale or
other disposition of all securities registered by such registration statements
(including such amendments as may be necessary to reflect different or
additional selling stockholders as a result of any distribution of Registrable
Securities by the Resale Holders to the beneficial owners of such Registrable
Securities); (iii) furnish to each Resale Holder such number of copies of any
prospectuses (including any preliminary prospectus and any amended, combined or
supplemented prospectus) in conformity with the requirements of the Securities
Act, and such other documents, as each Resale Holder may reasonably request in
order to effect the offering and sale of the Registrable Securities to be
offered and sold, but only while Parent shall be required under the provisions
hereof to cause the registration statements to remain effective; (iv) use its
reasonable best efforts to register or qualify the Registrable Securities
covered by such registration statements under the securities or blue sky laws of
such jurisdictions as each Resale Holder shall reasonably request (provided that
Parent shall not be required in connection therewith or as a condition thereto
to qualify to do business or to file a general consent to service of process in
any such jurisdiction where it has not been qualified), and do any and all other
acts or things which may be necessary or advisable to enable each Resale Holder
to consummate the public sale or other disposition of such Registrable
Securities in such jurisdictions; (v) notify each Resale Holder, promptly after
it shall receive notice thereof, of the date and time the registration
statements and each post-effective amendment to such registration statements
become effective or a supplement to any prospectus forming a part of such
registration statements has been filed; and (vi) promptly reissue, or promptly
authorize and instruct its transfer agent to reissue, unlegended certificates at
the request of any Resale Holder thereof upon such Resale Holder's delivery of
original certificates representing Registrable Securities tendered for sale
pursuant to such effective registration statements, and to promptly respond to
broker's inquiries made of the Parent in connection with such sales, in each
case with a view to reasonably assisting the Resale Holder to complete such sale
during such period of effectiveness.


                                     - 40 -
<PAGE>

          (c) Notwithstanding the foregoing obligation of Parent under this
Section 10.2, if Parent shall furnish to the Resale Holder or Resale Holders
requesting a registration statement pursuant to this Section 10.2 a certificate
signed by the President of Parent stating that in the good faith judgment of
Parent, it would be seriously detrimental to Parent and its stockholders for
such registration statement to be filed at such time and it is therefore
essential to defer the filing of such registration statement, Parent shall have
the right to defer such filing for a period of not more than 30 days beyond the
date specified under Section 10.2(a) above.

     10.3 Piggyback Registration.

          (a) Parent may determine to provide for the firmly underwritten sale
of Parent Common Stock for its own account and/or the account of other
stockholders, and in connection with such determination, shall file with the
Commission a registration statement to register such Common Stock (an
"Underwritten Sale").  In the event of such a determination, Parent will give to
each Resale Holder written notice thereof at least 15 days prior to the filing
of such registration statement, and will include in the Underwritten Sale (and
any related qualification under blue sky laws or other related compliance) all
the Registrable Securities specified by the Resale Holders in their written
request or requests to Parent, made within 10 days after receipt of such written
notice from Parent, subject, however, to the marketing and other limitations set
forth in Section 10.3(b) below; provided, however, that no Registrable
Securities shall be included in a registration statement filed with the
Commission if (i) the Registrable Securities have been sold in a registration
statement pursuant to Section 10.2 or (ii) the Parent reasonably determines that
the Underwritten Sale will not be completed (i.e., the registration statement is
not declared effective) within one year of the Effective Time.  An Underwritten
Sale, including the form of underwriting agreement to be entered into by Parent,
the underwriter(s) and any selling stockholders, shall be on customary terms.
The underwriter(s) for an Underwritten Sale shall be selected by Parent in its
sole discretion.

          (b) The right of any Resale Holder to registration pursuant to this
Section 10.3 shall be conditioned upon such Resale Holder's participation in the
Underwritten Sale and the inclusion of Registrable Securities in the
Underwritten Sale to the extent provided herein.  All Resale Holders
distributing Registrable Securities through the Underwritten Sale shall
(together with Parent and the other holders distributing their securities
through the Underwritten Sale) enter into an underwriting agreement in customary
form with the managing underwriter.  Notwithstanding any other provision of this
Section 10.3, if the Registrable Securities requested to be included in the
Underwritten Sale pursuant to this Section 10.3 exceeds twenty percent (20%) of
the total number of shares to be included in such registration, the Parent or
the managing underwriter, as the case may be, may limit the Registrable
Securities to be included in such registration and underwriting to twenty
percent (20%) of the total number of shares to be included in such registration
and underwriting, allocated among the Resale Holders in proportion, as nearly as
practicable, to the respective amounts of Registrable Securities requested to be
included by such Resale Holders in accordance with Section 10.3(a) above.  To
facilitate the allocation of shares in accordance with the above provision,
Parent or the underwriters may round the number of shares allocated to any
Resale Holder to the nearest 100 shares.  If any Resale Holder disapproves of
the terms of the Underwritten Sale, he or she may elect to withdraw therefrom by
written notice to Parent and the managing underwriter.

     10.4 Suspension of Prospectus.  Under any registration statement filed
pursuant to Section 10.2 hereof, Parent may restrict disposition of Registrable
Securities, and a Resale Holder will



                                     - 41 -
<PAGE>

not be able to dispose of such Registrable Securities, if Parent shall have
delivered a notice in writing to such Resale Holder stating that a delay in the
disposition of such Registrable Securities is necessary because Parent, in its
reasonable judgment, has determined in good faith that such sales would require
public disclosure by Parent of material nonpublic information that is not
included in such registration statement and that immediate disclosure of such
information would be seriously detrimental to Parent. In the event of the
delivery of the notice described above by Parent, Parent shall use its
reasonable best efforts to amend such registration statement and/or amend or
supplement the related prospectus if necessary and to take all other actions
necessary to allow the proposed sale to take place as promptly as possible,
subject, however, to the right of Parent to delay further sales of Registrable
Securities until the conditions or circumstances referred to in the notice have
ceased to exist or have been disclosed. Such right to delay sales of Registrable
Securities shall not exceed 75 days in the aggregate and no longer than 30 days
as to any single delay (any such period of delay herein referred to as a
"blackout period"); after the registration statement is declared effective, no
blackout period may be imposed during the 15-day period following the date of
effectiveness or the termination date of the last blackout period. In addition,
each Resale Holder who becomes an employee of Parent shall be subject to the
trading restrictions related to the release of quarterly results of operations
in the same manner as other employees of Parent.

     10.5 Expenses.  All of the out-of-pocket expenses incurred in connection
with any registration of Registrable Securities pursuant to this Article X,
including, without limitation, all Commission, Nasdaq National Market and blue
sky registration and filing fees, printing expenses, transfer agents' and
registrars' fees, and the reasonable fees and disbursements of Parent's outside
counsel and independent accountants shall be paid by Parent.  Parent shall not
be responsible to pay any legal fees for any Resale Holder or any selling
expenses of any Resale Holder (including, without limitation, any broker's fees
or commissions, including underwriter commissions).

     10.6 Indemnification.  In the event of any offering registered pursuant to
this Article X:

          (a) Parent will indemnify each Resale Holder, each of its officers,
directors and partners and such Resale Holder's legal counsel and independent
accountants, and each person controlling such Resale Holder within the meaning
of Section 15 of the Securities Act, with respect to which registration,
qualification or compliance has been effected pursuant to this Article X, and
each underwriter, if any, and each person who controls any underwriter within
the meaning of Section 15 of the Securities Act, against all expenses, claims,
losses, damages and liabilities (or actions in respect thereof), including any
of the foregoing incurred in settlement of any litigation, commenced or
threatened, arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact contained in any registration statement,
prospectus, offering circular or other document, or any amendment or supplement
thereto, incident to any such registration, qualification or compliance, or
based on any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances in which they are made, not misleading, or any
violation by Parent of any rule or regulation promulgated under the Securities
Act, or state securities laws, or common law, applicable to Parent in connection
with any such registration, qualification or compliance, and will reimburse (and
advance the same to) each such Resale Holder, each of its officers, directors
and partners and such Resale Holder's legal counsel and independent accountants,
and each person controlling such Resale Holder, each such underwriter and each
person who controls any such underwriter, for any legal and any other expenses
reasonably incurred in connection with investigating, preparing or defending any
such claim, loss, damage, liability or action,



                                     - 42 -
<PAGE>

provided that Parent will not be liable in any such case to the extent that any
such claim, loss, damage, liability or expense arises out of or is based in any
untrue statement or omission or alleged untrue statement or omission, made in
reliance upon and in conformity with written information furnished to Parent in
an instrument duly executed by such Resale Holder or underwriter and stated to
be specifically for use therein; provided, however, that the foregoing is
subject to the condition that, insofar as it relates to any such untrue
statement, alleged untrue statement, omission or alleged omission made in a
preliminary prospectus on file with the Commission at the time the registration
statement becomes effective or the amended prospectus is filed with the
Commission pursuant to Rule 424(b) (the "Final Prospectus"), the provisions
hereof shall not inure to the benefit of any Resale Holder, if the Parent had
complied with its obligations under Section 10.2(b)(iii) with respect to such
Final Prospectus and a copy of the Final Prospectus was not furnished to the
person asserting the loss, liability, claim or damage at or prior to the time
such action is required by the Securities Act, and if the Final Prospectus would
have cured the defect giving rise to the loss, liability, claim or damage.

          (b) Each Resale Holder will, if Registrable Securities held by such
Resale Holder are included in the securities as to which such registration,
qualification or compliance is being effected, indemnify Parent, each of its
directors and officers and its legal counsel and independent accountants, each
underwriter, if any, of Parent's securities covered by such a registration
statement, each person who controls Parent or such underwriter within the
meaning of Section 15 of the Securities Act, and each other such Resale Holder,
each of its officers and directors and each person controlling such Resale
Holder within the meaning of Section 15 of the Securities Act, against all
claims, losses, damages and liabilities (or actions in respect thereof) arising
out of or based on any untrue statement (or alleged untrue statement) of a
material fact contained in any such registration statement, prospectus, offering
circular or other document, or any omission (or alleged omission) to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse Parent, such Resale
Holders, such directors, officers, legal counsel, independent accountants,
underwriters or control persons for any legal or any other expenses reasonably
incurred in connection with investigating or defending any such claim, loss,
damage, liability or action, in each case to the extent, but only to the extent,
that such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such registration statement, prospectus, offering circular
or other document in reliance upon and in conformity with written information
furnished to Parent by an instrument duly executed by such Resale Holder and
stated to be specifically for use therein; provided, however, that the
obligations of such Resale Holders hereunder shall be limited to an amount equal
to the net proceeds received by each such Resale Holder of Registrable
Securities actually sold as contemplated herein.

          (c) Each party entitled to indemnification under this Section 10.6
(the "Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has written notice of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not be unreasonably
withheld), and the Indemnified Party may participate in such defense at such
party's expense, and provided further that the failure of any Indemnified Party
to give notice as provided herein shall not relieve the Indemnifying Party of
its obligations under this Article X; provided that if the Indemnified Party has
claims against the Indemnifying Party or otherwise has claims or defenses
different from or in addition to those of the Indemnifying Party, the
Indemnified



                                     - 43 -
<PAGE>

Party may retain counsel of its own choice for all Resale Holders, and the
reasonable fees and expenses of such counsel shall be paid by the Indemnifying
Party. No Indemnifying Party, in the defense of any such claim or litigation,
shall, except with the consent of each Indemnified Party, consent to entry of
any judgment or enter any settlement which does not include as an unconditional
term thereof the giving by the claimant or plaintiff to the Indemnified Party of
a release from all liability in respect to such claim or litigation.

          (d) The obligations of Parent and each Resale Holder under this
Section 10.6 shall survive the completion of any offering of Registrable
Securities in a registration statement under this Article X and otherwise.

          (e) Notwithstanding the foregoing, to the extent the provisions of
this Section 10.6 are inconsistent with or conflict with the terms of any
underwriting, indemnification, selling or similar agreement entered into by a
Resale Holder in connection with the offer and sale of Registrable Securities
pursuant to a registration effected pursuant to this Article X, the terms of
such agreement shall govern and shall supersede the provisions of this Article
X.

     10.7 Limitation on Assignment of Registration Rights  The rights to cause
Parent to register Registrable Securities pursuant to this Article X may not be
assigned by a Resale Holder unless such a transfer is to stockholders, partners
or retired partners, or members or retired members of a Resale Holder (including
spouses and ancestors, lineal descendants, and siblings of such stockholders,
partners, members or spouses who acquire Registrable Securities by right, will,
or intestate succession) and all such transferees or assignees agree in writing
to appoint a single representative as their attorney-in-fact for the purpose of
receiving any notices and exercising their rights under this Article X.  Prior
to a permitted transfer of registration rights under this Article X, a Resale
Holder must furnish Parent with written notice of the name and address of such
transferee and the Registrable Securities with respect to which such
registration rights are being assigned and a copy of a duly executed written
instrument in form reasonably satisfactory to Parent by which such transferee
assumes all of the obligations and liabilities of its transferor hereunder and
agrees itself to be bound hereby.  No transfer of registration rights under this
Article X shall be permitted if immediately following such transfer the
disposition of such Registrable Securities by the transferee is not restricted
under the Securities Act; provided that Parent shall have provided such
transferee with certificates representing such Registrable Securities free of
any transfer restrictions and Parent shall have instructed the transfer agent
for such Registrable Securities to remove any stop transfer or other
instructions.


                                   ARTICLE XI

                                  TERMINATION


     In the event the Closing has not occurred on the date of this Agreement,
then Parent, Merger Sub and Natchez further agree as follows:

     11.1  Mutual Agreement.  This Agreement may be terminated at any time prior
to the Effective Time by the written consent of Parent and Natchez.


                                     - 44 -
<PAGE>

     11.2  Termination by Parent.  This Agreement may be terminated by Parent
(provided that it is not then in material breach of any representation,
warranty, covenant or agreement contained in this Agreement) alone, by means of
written notice to Natchez, if there has been a material breach by Natchez of any
representation, warranty, covenant or agreement set forth in this Agreement or
other ancillary agreements, which breach would result in a failure to satisfy
the closing conditions contained in Section 8.2 and has not been cured within
five (5) business days following receipt by Natchez of notice of such breach.

     11.3  Termination by Natchez.  This Agreement may be terminated by Natchez
(provided that it is not then in material breach of any representation,
warranty, covenant or agreement contained in this Agreement) alone, by means of
written notice to Parent, if there has been a material breach by Parent of any
representation, warranty, covenant or agreement set forth in the Agreement or
other ancillary agreements, which breach would result in a failure to satisfy
the closing conditions contained in Section 8.3 and has not been cured within
five (5) business days following receipt by Parent of notice of such breach,

     11.4  Outside Date.  This Agreement may be terminated by Parent alone or by
Natchez alone by means of written notice if the Effective Time does not occur on
or prior to October 31, 1999; provided, however, that the right to terminate
this Agreement pursuant to the preceding clause will not be available to any
party whose failure to fulfill any obligation under this Agreement has been a
significant cause of, or resulted in, the failure of the Effective Time to occur
on or before such date.

     11.5  Effect of Termination.  In the event of termination of this Agreement
by either Natchez or Parent as provided in this Article XI, this Agreement will
forthwith become void and have no effect, and there will be no liability or
obligation on the part of Parent, Natchez, Merger Sub or their respective
officers or directors, except that (i) the provisions of Sections 7.5, 7.7, 7.8
and 12.2 will survive any such termination and abandonment, and (ii) no party
will be released or relieved from any liability arising from the willful breach
by such party prior to termination of any of its representations, warranties,
covenants or agreements as set forth in this Agreement.


                                  ARTICLE XII

                                 MISCELLANEOUS


     12.1  Entire Agreement.  Except for the Confidentiality Agreement, this
Agreement, including the exhibits, schedules and other agreements delivered
pursuant to this Agreement contain all of the terms and conditions agreed upon
by the parties relating to the subject matter of this Agreement and supersede
all prior agreements, negotiations, correspondence, undertakings and
communications of the parties, whether oral or written, respecting that subject
matter.

     12.2  Governing Law; Consent to Jurisdiction.  The Merger will be governed
by the DGCL to the extent applicable, and all other aspects of this Agreement
will be governed by the internal laws of the Commonwealth of Massachusetts.
Legal proceedings relating to this Agreement, the agreements executed in
connection with this Agreement or the transactions contemplated hereby or
thereby that are commenced against Parent, Merger Sub or the Surviving
Corporation may be commenced only in the



                                     - 45 -
<PAGE>

state or federal courts in Boston, Massachusetts. Each of the parties hereby
consents to the exclusive jurisdiction of such courts (and of the appropriate
appellate courts) in any such action or proceeding and waives any objection to
venue laid therein. The foregoing provisions will not be construed to preclude
any party from bringing a counter-claim in any action or proceeding properly
commenced in accordance with the foregoing provisions. Process in any such
action or proceeding may be served on any party anywhere in the world.
Notwithstanding the foregoing, any dispute relating to a claim under the Escrow
Agreement will be resolved in accordance with the arbitration provisions of the
Escrow Agreement.

     12.3  Notices.   All notices, requests, demands or other communications
which are required or may be given pursuant to the terms of this Agreement will
be in writing and will be deemed to have been duly given: (i) on the date of
delivery if personally delivered by hand, (ii) upon the third day after such

     Such addresses may be changed, from time to time, by means of a notice
given in the manner provided in this Section 12.3.

     12.4  Severability.  If any provision of this Agreement is held to be
unenforceable for any reason, it will be modified rather than voided, if
possible, in order to achieve the intent of the parties to this Agreement to the
extent possible.  In any event, all other provisions of this Agreement will be
deemed valid and enforceable to the full extent.

     12.5  Survival of Representations and Warranties.  All representations and
warranties contained in this Agreement, including the exhibits and schedules
delivered pursuant to this Agreement, will survive the Effective Time, but any
claims for breach thereof may only be made within any applicable time limits
specified herein or in the Escrow Agreement.

     12.6  Assignment.  No party to this Agreement may assign, by operation of
law or otherwise, all or any portion of its rights, obligations, or liabilities
under this Agreement without the prior written consent of Natchez, Merger Sub
and Parent, which consent may be withheld in the absolute discretion of the
party asked to grant such consent; provided however, that Parent and Merger Sub
may assign their respective rights hereunder (i) to their respective affiliates
or (ii) in connection with any sale of Parent by means of a sale of all or
substantially all of Parent's assets or by means of a merger, consolidation,
recapitalization or reorganization of Parent in each case involving all or
substantially all of the capital stock or assets of Parent; provided that Parent
shall remain liable for its obligations hereunder.  Subject to the preceding
sentence, this Agreement shall be binding upon, inure to the benefit of and be
enforceable by the parties and their respective successors and assigns.  Any
attempted assignment by Merger Sub or Parent, on the one hand, or by Natchez, on
the other hand, in violation of this Section 12.6 will be voidable and will
entitle Natchez or Parent, respectively, to terminate this Agreement at its
option.

     12.7  Counterparts.  This Agreement may be executed in two or more
partially or fully executed counterparts each of which will be deemed an
original and will bind the signatory, but all of which together will constitute
but one and the same instrument.  The execution and delivery of a Signature Page
to Agreement and Plan of Reorganization in the form annexed to this Agreement,
including a facsimile copy of the actual signature, by any party hereto who will
have been furnished the final form of this Agreement will constitute the
execution and delivery of this Agreement by such party.

     12.8  Amendment.  This Agreement may not be amended except by an instrument
in writing executed by Natchez, Merger Sub and Parent; provided however, that no
such amendment which materially adversely affects the rights or obligations of
any Stockholder will be made without the written consent of such Stockholder.

     12.9  Extension, Waiver.  At any time prior to the Effective Time, any
party hereto may, to the extent legally allowed: (i) extend the time for the
performance of any of the obligations or other acts of any other party hereto to
the party extending such time, (ii) waive any inaccuracies in the
representations and warranties made to such party contained herein or in any
