may be) shall deliver to the Escrow Agent a certification in the form of
EXHIBIT A to the Escrow Agreement.  The Escrow Agent shall disburse to the
Buyer the amount, if any, by which the Adjusted Purchase Price is less than the

Indemnification Allowance the amount paid by the Company to such taxing
authority.

Subsidiary shall have given written notice to the Company and Escrow Agent of a
claim or claims by Centrum Subsidiary against the Company arising from a breach
of the Company of any of the provisions of this Agreement (a "Buyer Claim"),

including interest accrued thereon, to the Company.

                 (g)      If Escrow Agent receives written notice from Centrum
Subsidiary of a Buyer Claim prior to November 1, 1998, Escrow Agent shall hold,
retain and not

Centrum Subsidiary, or a final order of a court of competent jurisdiction,
directing Escrow Agent to disburse the Indemnification Allowance to the
Company, any taxing authority or any claimant whose Buyer Claim is based upon a

Schedule and any other exhibits, does not contain any untrue statement of a
material fact or omit to state any material fact necessary in order to make the
statements and information contained herein, in light of the circumstances in
which they are made, not misleading.  To the Knowledge of the Company, there is

the officers or directors of the Company are aware and which is or could

         5.  PRE-CLOSING COVENANTS.  The Parties agree as follows with respect

                 (e)      FULL ACCESS.  The Company will permit representatives

written notice to the Buyer of any material development affecting the Assets,
Liabilities, business, financial condition, operations, results of operations,
or future prospects of the Company, or any matter hereafter arising which, if
existing, occurring or known at the date of this Agreement would have been
required to be disclosed to Buyer or which would render inaccurate any of the
representations, warranties or statements set forth in Section 4 hereof.  Each
party will give prompt written notice to the other of any material development
affecting the ability of the Parties to consummate the transactions
contemplated by this Agreement.

                 (g)      EXCLUSIVITY.  Neither Duke, Duke Seabridge, nor any
of the Company's directors, officers, managerial employees, nor any of their
respective representatives, agents or Affiliates shall directly or indirectly

performance by Duke, Duke Seabridge and the Company of their obligations under
this Agreement or solicit, initiate, encourage, respond favorably to or condone

(i) to hold harmless, indemnify and defend Buyer from and against any and all
losses, claims, suits, demands, damages, costs or expenses of any nature

will give Buyer written notice specifying the nature of the matter of which the
Company has become aware, what action the Company is taking or proposes to take
with respect thereto, and, as soon as known by the Company, what action is

Service, by the PBGC, by the United States Department of Labor, and/or by any
other Governmental Authority:

                       (i)    Any proposed or final determination by the
Internal Revenue Service, by the PBGC, by the United States Department of
Labor, or by any other Governmental Authority that any Company Plan is not in
compliance with any applicable provisions of ERISA, the Code, or other

                       (iii)  Any impairment, however occasioned, of the
Company's authority to





                                       43


   49

administer, interpret, amend, suspend, and/or terminate any Company Plan;

                       (iv)  With respect to any Related Company Plan that is a

not waived) within the meaning of ERISA Sec. 302(a)(2); the existence of a lien
against any of the Company's assets in favor of any such Plan pursuant to ERISA
Sec. 302(f); or the adoption of a Plan amendment by reason of which the Company
is or may be required to provide security to such Plan pursuant to Code Sec.
401(a)(29);

                       (v)  With respect to any Related Company Plan that is a

from such Plan or the intention of any party, including the PBGC, to terminate
or withdraw from such Plan under circumstances whereby any Liability could be
asserted against the Company in connection therewith; the assertion against the
Company of any Liability to such Plan, to the PBGC, or to any other party in
connection with the termination of or any withdrawal from such Plan; or the
filing or a threat of filing of a lien against any asset of the Company in
connection with any such asserted Liability.  Without the advance written
consent of Buyer, the Company shall not:

                 (a)      amend or modify any Company Plan listed on SCHEDULE
                          4(V) in any respect which is materially adverse to
                          Buyer's interests; nor

                 (b)      adopt or become obligated to contribute to any
                          Employee Benefit Plan not listed on SCHEDULE 4(V).

For purposes hereof, any increase in the cost of or rate of contributions to
any Company Plan or any impairment of the Company's authority to administer,
interpret, amend, suspend, and/or terminate any Company Plan, however
occasioned, shall be treated as a modification of such Plan and as subject to
this paragraph, whether or not it results from an amendment to the governing
documents of such Plan.

                 (l)      ENVIRONMENTAL REPORTS.  The Company and Buyer jointly
and severally agree that:


                          (i)  Buyer may obtain, at its expense, within fifteen
(15) days after the acceptance of this Agreement, a report of a Phase I
environmental assessment ("Phase I Assessment") of the Real Property and of all
real property previously owned or leased by the Company prepared by a
registered engineer of Buyer's choice experienced in preparing such
assessments.  The Phase I Assessment, if any, shall be certified to Buyer.
Company shall cooperate with any engineer or other parties which Buyer utilizes
to effect such assessments.

    The Phase I Assessment shall, at a minimum, comply with the American Society





                                       44


   50

specifically include a review of a disclosure questionnaire fully and
accurately completed by the Company and interviews of any employees of the
Company and owners of land adjacent to the Real Property.

         If a Phase II Assessment is recommended or if Buyer is not satisfied
with the results of such Phase I Assessment, Buyer shall have the right within
three (3) business days after receipt of the Phase I Assessment to terminate
this Agreement. The Company shall have no right to terminate this Agreement due
to the results of Buyer's environmental assessment.

                 (m)      LOAN.  Centrum Subsidiary shall use its best efforts
to obtain a loan commitment from Huntington National Bank upon terms
substantially similar to the Loan Proposal and, once obtained, to close on such

                 (n)      Intentionally deleted.

                 (o)      CONFIDENTIALITY.  In the event the transaction
contemplated herein is not consummated, the Buyer will treat and hold as such
all of the Confidential Information, refrain from using any of the Confidential
Information except in connection with this Agreement, and deliver promptly to
the Company or destroy, at the request and option of the Company, all tangible
embodiments (and all copies) of the Confidential Information which are in
Buyer's possession, or in the possession of Buyer's agents or representatives.
In the event that the Buyer is requested or required (by oral question or
request for information or documents in any legal proceeding, interrogatory,
subpoena, civil investigative demand, or similar process) to disclose any
Confidential Information, the Buyer will notify the Company, promptly of the
request or requirement so that the Company may seek an appropriate protective
order or the receipt of a waiver of compliance with the provisions of this
Section 6(b).  If, in the absence of a protective order or the receipt of a
waiver hereunder, the Buyer is, on the advice of counsel, compelled to disclose
the Confidential Information to the tribunal or else stand liable for contempt,
the Buyer may disclose the Confidential Information to the tribunal; provided,
however, that the Buyer shall use all its best efforts to obtain, at the
request of the Company, an order or other assurance that confidential treatment
will be accorded to such portion of the Confidential Information required to be
disclosed as the Company shall designate.  The foregoing provisions shall not
apply to any Confidential Information which is generally available to the
public immediately prior to the time of disclosure through no fault of Buyer.
As used in this Agreement, the term "Confidential Information" means all trade
secrets, proprietary information, confidential business information, and/or
confidential or proprietary Know-How of the Company disclosed to the Buyer
(including ideas, formulas, compositions, inventions (whether patentable or
unpatentable and whether or not reduced to practice), drawings, specifications,
designs, plans, proposals,

pricing and cost information, business and marketing plans, and customer and
supplier lists and information), but does not include information which:  (i)
is at the time of disclosure a part of the public domain or thereafter becomes
part of the public domain through no violation of this Agreement; (ii) becomes
available to the Buyer on a nonconfidential basis from a source other than the
Buyer, provided that such source is not bound by a confidentiality agreement
with Company or Buyer; (iii) is independently developed by or for the Buyer by
persons who have not had direct or indirect access to such Confidential
Information; (iv) was disclosed by the Company to actual or potential customers
or suppliers in the Ordinary Course of Business prior to the Closing Date
without assurance of confidential treatment; or (v) is described by Buyer on
SCHEDULE 6(B).

                 (p)      intentionally deleted.

                 (q)      DUKE'S COVENANTS

                          (i)  Duke, in its capacity as sole shareholder of the
Company, shall do or refrain from doing all acts and things in order to ensure
that the representations and warranties of the Company in Sections 3 and 4
hereof remain true and correct at the Closing as if such representations and
warranties were made at and as of such date and to satisfy or cause or to be
satisfied the conditions in Section 7 which are within the control of Duke and
shall use best efforts to ensure that the Company complies with its covenants
in this Agreement.

                          (ii) Duke further agrees that it will (a) vote all 
shares owned by it or which it has the right to vote in favor of the
transaction contemplated herein and the adoption of this Agreement, and against
any other proposal which would be inconsistent with the completion of the
transaction contemplated herein, and (b) not at any time prior to Closing Date
without the consent of the Buyer, sell, transfer, pledge, hypothecate or
otherwise dispose of any shares of the Company owned by it; provided that should
Duke sell, transfer, pledge, hypothecate or otherwise dispose of any shares of
the Company owned by it after the Closing Date, Duke shall become liable for all
of the Company's obligations under this Agreement, including without limitation,
all provisions of Article 8 hereof.

                 (r)      DUKE SEABRIDGE'S COVENANTS

                          (i)  Duke Seabridge, in its capacity as sole
shareholder of Duke, shall refrain from doing any acts and things that would
render the representations and warranties of Duke in Sections 3 and 4 hereof
untrue or not correct in any material respect at the Closing as if such
representations and warranties were made at and as of such date.





                                       46

                          (ii) Duke Seabridge further agrees that it will (a) 
vote all shares owned by it or which it has the right to vote in favor
of the transaction contemplated herein and the adoption of this Agreement, and

owned by it.

         6.  POST-CLOSING COVENANTS.  The Parties agree as follows with respect
to the period following the Closing.

                 (a)      GENERAL.  In case at any time after the Closing any
further action is necessary or desirable to carry out the purposes of this
Agreement, each of the Parties will take such further action (including the
execution and delivery of such further instruments and documents) as any other
Party reasonably may request, all at the sole cost and expense of the
requesting Party (unless the requesting Party is entitled to indemnification
therefor under Section 8 below).  The Company acknowledges and agrees that from
and after the Closing the Buyer will be entitled to possession of all
documents, books, records, agreements, and financial data of any sort relating
to the Company or the Assets, other than the Company's corporate minute book,
and materials directly relating to the Retained Liabilities; provided, however,
that Buyer shall allow the Company access to such materials upon the request of
the Company.

                 (b)      CONFIDENTIALITY.  The Company will treat and hold as
such all of the Confidential Information, refrain from using any of the
Confidential Information except in connection with this Agreement, and deliver
promptly to the Buyer or destroy, at the request and option of the Buyer, all
tangible embodiments (and all copies) of the Confidential Information which are
in its possession; provided, however, that this provision shall not apply to
Confidential Information directly related to the Retained Liabilities.  In the
event that the Company is requested or required (by oral question or request
for information or documents in any legal proceeding, interrogatory, subpoena,
civil investigative demand, or similar process) to disclose any Confidential
Information, the Company will notify the Buyer, promptly of the request or
requirement so that the Buyer may seek an appropriate protective order or the
receipt of a waiver of compliance with the provisions of this Section 6(b).
If, in the absence of a protective order or the receipt of a waiver hereunder,
the Company is, on the advice of counsel, compelled to disclose the
Confidential Information to the tribunal or else stand liable for contempt, the
Company may disclose the Confidential Information to the tribunal; provided,
however, that the Company shall use all its best efforts to obtain, at the
request of the Buyer, an order or other assurance that confidential treatment
will be accorded to such portion of the Confidential Information required to be
disclosed as the Buyer shall designate.

                 (c)      LITIGATION SUPPORT.  In the event and for so long as
any Party actively is contesting or defending against any charge, complaint,
action, suit, proceeding,





                                       47


   53

hearing, investigation, claim, or demand in connection with (i) any transaction
contemplated under this Agreement or (ii) any fact, situation, circumstance,
status, condition, activity, practice, plan, occurrence, event, incident,
action, failure to act, or transaction on or prior to the Closing Date
involving the Company each of the other Parties will cooperate with it and its
counsel in the contest or defense, make available their personnel, and provide
such testimony and access to their books and records as shall be necessary in
connection with the contest or defense, all at the sole cost and expense of the
contesting or defending Party (unless the contesting or defending Party is
entitled to indemnification therefor under Section 8 below).

                 (d)      TRANSITION.  The Company will not take any action
that primarily is designed or intended to have the effect of discouraging any
lessor, licensor, customer, supplier, or other business associate of the
Company from maintaining the same business relationships with the Buyer after
the Closing as it maintained with the Company prior to the Closing.  The
Company will refer all customer inquiries relating to the business of the
Company to the Buyer from and after the Closing.

                 (e)      RETENTION OF BOOKS AND RECORDS.  Buyer will retain
for three (3) years after the Closing Date all books, records and other
documents pertaining to the Assets in existence on the Closing Date and to make
the same available after the Closing Date for inspection.

                 (f)      Intentionally deleted.

                 (g)      EMPLOYMENT.  Centrum Subsidiary intends to make
offers of employment at Closing to substantially all of the employees of the
Company, and all employees of the Company hired by Centrum Subsidiary shall be
entitled to full seniority credit as to benefits for the time of their
employment with the Company.  The making and content of any communication to
this effect by the Company to any of its employees will be preapproved by
Buyer.  Centrum Subsidiary reserves the right to make offers of employment
under terms and conditions satisfactory to Centrum Subsidiary.  The Company
will assist Buyer in hiring any of such employees and for a period of three (3)
years will not directly or indirectly employ any of such employees in the
employ of Buyer without first having obtained Buyer's consent.  It is
understood, however, that Buyer neither has nor assumes any obligation to hire
or engage all or substantially all of the employees of the Company.  The
Company will pay all severance pay or benefits, vacation pay, sick pay, accrued
pension benefits, wages, commissions, and other compensation due to Company's
employees up to and including the Closing Date.  In view of the foregoing, the
Company and Buyer do not anticipate the need for the issuance by either party
of any notices under the federal Worker Assistance and Retraining Notification
Act, to the extent otherwise applicable.

                 (h)      COMPANY PLANS.  The Company will be responsible for

of the Real Property.  Prorations and adjustments for utilities and other
charges and/or credits incident to the operation of the Company shall be made
on the Closing Date, or as soon thereafter as the correct amounts can be
determined.  The Company shall either pay directly or deliver payment to Buyer
for the Company's Liabilities incurred to the Closing Date as soon thereafter
as is practicable, but in no event later than sixty (60) days after Closing, or
when due, whichever is later; provided, however, that this provision shall not
apply to Liabilities which are being contested in good faith by the Company.

                 (j)      USE OF NAME.  At Closing, the Company shall assign to
Buyer all of the Company's right, title and interest in and to the Tradename
and immediately change its name to a corporate name not using the words

and assigns not to use the Tradename or any combination or variation thereof in
any manner or way whatsoever from and after the Closing Date; and shall consent
to Buyer using any or all of the Tradename and cooperate with Buyer in filing
all necessary consents required under applicable Washington and federal Law for
the use of the Tradename.

                 (k)      PAYMENTS RECEIVED BY COMPANY AFTER CLOSING.  The
Company hereby agrees that if the Company receives any payment or credit or an
account receivable not pertaining to any Retained Assets or Retained
Liabilities ("Payment") on or after the Closing Date, such Payment shall be the
property of and belong to Buyer and promptly shall be delivered to Buyer by the
Company.  The Company agrees to cooperate fully in making any necessary
endorsements to any instruments received as Payment, and further agrees that
Buyer is hereby authorized to endorse any such instrument in the name of the
Company and deposit such instrument into any account of Buyer, or negotiate or
otherwise dispose of such instrument as Buyer sees fit.

                 (l)      ACCOUNTS RECEIVABLE COLLECTION.  The Assets which are
being sold hereunder shall include all accounts receivable of the Company as
reflected on the Company's books as of the Closing Date.  In connection with
the sale of the accounts receivable, the Company agrees to execute such
instruments of transfer, conveyance and assignment as may be reasonably
requested by Buyer to give effect to such sale.


                        (i)  Buyer agrees to use its best efforts to collect
such accounts receivable as are sold hereunder by the Company.  This shall
include, but not be limited to, at least one (1) written contact by mail or
wire during each thirty (30) day period for each account debtor who is in

each such account debtor at least once by mail or wire and once by phone during
each thirty (30) day period.  With respect to each account receivable which is
sold to Buyer by the Company hereunder, Buyer agrees to apply all payments
received by it from the account debtor following the Closing Date to the
account receivable which is being sold herein unless the account debtor is
disputing in good faith the account or the  product or service sold to the
account debtor which gave rise to the account.
                        
                        (ii)  With respect to those accounts receivable, if

being sold by the Company hereunder, Buyer shall provide the Company with a
written status report at the end of each month.  In addition, Buyer agrees to
cooperate with the Company and orally respond to reasonable requests from the
Company as to the status of any account.

contract exists which would be assigned to Buyer but for a nonassignment
provision in such contract or a federal, state, local Law which makes such
assignment by Company legally invalid ("Nonassignable Contract"), Company will
remain primarily liable on that contract, but will transfer to Buyer all
benefits under the Nonassignable Contract in exchange for Buyer undertaking all
of Company's obligations under the Nonassignable Contract.

applicable survival period, or in the event Buyer is named as a defendant  in
any litigation with respect to a Liability of the Company which is not an
Assumed Obligation, then the Company and Duke agree to indemnify the Buyer and
its Affiliates and hold them harmless from and against the entirety of any
Adverse Consequences the Buyer may suffer, sustain or become subject to through
and after the date of the claim for indemnification (including any Adverse
Consequences the Buyer may suffer after the end of the applicable survival
period) resulting from, arising out of, relating to, in the nature of, or
caused by the breach.  In the event Duke Seabridge breaches any of its
covenants contained herein, then Duke Seabridge agrees to indemnify the Buyer

Adverse Consequences that the Company may suffer through and after the date of
the claim for indemnification resulting from, arising out of, relating to, in
the nature of, or caused by the breach.

                 (d)      PROCEDURE FOR INDEMNIFICATION.

                          (i)     The Party seeking indemnification (the
"Indemnified Party") agrees to give the party from whom indemnification is
sought (the "Indemnifying Party") prompt written notice of any claims with
respect to which the Indemnifying Party has agreed to indemnify the Indemnified
Party under Section 8(b) and Section 8(c).  Upon request, the Indemnified Party
shall give the Indemnifying Party access to such





                                       56


   62

information possessed by the Indemnified Party as the Indemnifying Party
reasonably requests relating to such claim.

                          (ii)    The Indemnified Party shall initially
undertake the defense of any third party claim (at the expense of the
Indemnifying Party) until the Indemnifying Party notifies the Indemnified Party
in writing that the Indemnifying Party is assuming the defense of such claim,
whether or not involving litigation; provided, however, that the Indemnifying
Party may assume such defense while reserving the right to contest the
Indemnified Party's entitlement to indemnification; and provided further that
the Indemnified Party may at any time, at its election, participate (including
through representation by attorneys of its own) in such defense; provided that
such participation shall be at the Indemnified Party's own expense unless the
named parties to such claim (including any impleaded parties) include both the
Indemnified Party and the Indemnifying Party and the Indemnified Party shall
have been advised by counsel that there are one or more legal defenses
available to it which are different from or additional to those available to
the Indemnifying Party, it being understood, however, that in such case the
Indemnifying Party shall not, in connection with any one such action or
separate but substantially similar or related actions in the same jurisdiction
arising out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys.  At
the Indemnifying Party's reasonable request, the Indemnified Party will
cooperate with the Indemnifying Party in the preparation of such defense if the
Indemnifying Party reimburses the Indemnified Party for the reasonable expenses
incurred in connection with such request.  The Indemnifying Party shall not
settle any such claim for consideration other than money without the prior
written consent of the Indemnified Party and the Indemnifying Party shall not,
without the prior written consent of the Indemnified Party, settle or
compromise any claim or consent to the entry of any judgment that 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
of such claim (or, if the claims by the claimant or plaintiff are broader than
the Indemnifying Party's indemnification obligation, in respect of such portion
of such claim to which the Indemnifying Party has an indemnification
obligations under this Section 8.)  The Indemnifying Party contesting or
defending a third party claim shall afford to the Indemnified Party and its
counsel an opportunity to be present (as long as no participant to such
conferences objects) in conferences with all persons, including governmental
authorities, asserting such claims and conferences with representatives or
counsel for such persons at such other party's sole cost and expense.

                          (iii)   If the Indemnifying Party does not assume the
defense of a third party claim in a timely manner, then the Indemnified Party
may do so upon reasonable notice to the Indemnifying Party.  Reasonable
attorneys' fees and court costs incurred by the Indemnified Party for such
defense shall, without duplication be included as Adverse Consequences for
which the Indemnifying Party is responsible to the extent otherwise provided in
this Agreement.

                          (iv)    intentionally deleted.

                 (e)      RIGHTS OF SETOFF AGAINST THE ESCROW.  The Buyer shall
have the option to recover all or any part of its losses (in lieu of seeking
any cash indemnification therefor to which it is entitled under this Section 8)
by notifying the Company that the Buyer is making a Buyer Claim against the
escrow referred to in Section 2.6 hereof.

                 (f)      EXCLUSIVE REMEDY; INSURANCE.   The foregoing
indemnification provisions shall be the sole and exclusive remedy for matters
the subject thereof.  Pursuant to the foregoing, all claims, whether stated in
contract, tort, or otherwise, with respect to matters which are the subject of
potential indemnification pursuant to the foregoing provisions, shall be
subject to the deductibles, caps, limitations and procedures contained herein.
No indemnification shall be made for claims which are covered or reimbursable
by the claiming Party's insurance to the extent such insurance proceeds are
received by the claiming Party.

                 (g)      CERTAIN LIMITATIONS.  The liability of the Company
and Duke for claims under this Section 8 shall be limited by the following:

                          (i)  The Company and Duke shall have no obligation
under this Section 8 or this Agreement or otherwise with respect to the
representations and warranties made by the Company and Duke in this Agreement
after the expiration of the designated survival period, except for specifically
identified claims with respect to which Buyer or its successors or assigns has
given written notice prior to such date.


                          (ii)   The Company and Duke shall have no liability
for breach of any representation and warranty made hereunder, unless the
aggregate amount of all Adverse Consequences incurred by Buyer and its
successors and assigns in connection with claims relating to breaches of the
Company or Duke's representations and warranties equals at least Twenty-Five
Thousand Dollars ($25,000.00) in the aggregate (the "Threshold Amount");
provided, however, once the Threshold Amount has been met, the Company and Duke
shall be liable to the extent of the Adverse Consequences incurred by Buyer,
its successors and assigns in excess of Twelve Thousand Five Hundred Dollars
($12,500.00).

                          (iii)    Anything to the contrary contained in this
Agreement notwithstanding, in the absence of intentional misrepresentation or
fraud, the Company and Duke's liability for breach of any representation and
warranty made by them in this Agreement shall not exceed the sum of Five
Hundred Thousand Dollars ($500,000.00).

unless the context requires otherwise.  The Parties intend that each
representation, warranty, and covenant contained herein shall have independent
significance.  If any Party has breached any representation, warranty, or
covenant contained herein in any respect, the fact that there exists another
representation, warranty, or covenant relating to the same subject matter

breached shall not detract from or mitigate the fact that the Party is in
breach of the first representation, warranty, or covenant.

                 (m)      INCORPORATION OF EXHIBITS AND SCHEDULES.  The
Exhibits and Schedules identified in this Agreement are incorporated herein by

injunction or injunctions to prevent breaches of the provisions of this

provisions hereof in any action instituted in any court of the United States or
any state thereof having jurisdiction over the Parties and the matter (subject

remedy to which they may be entitled, at Law or in equity.

submits to the jurisdiction of any state or federal court sitting in
Minneapolis, Minnesota, in any action or proceeding arising out of or relating
to this Agreement, agrees that all claims in respect of the action or
proceeding may be heard and determined in any such court, and agrees not to
bring any action or proceeding arising out of or relating to this Agreement in
any other court.  Each of the Parties waives any defense of inconvenient forum
to the maintenance of any action or proceedings so brought and waives any bond,
surety, or other security that might be required of any other Party with
respect thereto.  Any Party may make service on any other Party by sending or
delivering a copy of the process to the Party to be served at the address and
in the manner providing for the giving of notices in Section 10(g) above.
Nothing in this Section 10(o), however, shall affect the right of any Party to
serve legal process in any other manner permitted by Law.  Each of the Parties
agrees that a final judgment in any action of proceeding so brought shall be
conclusive and may be enforced by suit on the judgment or in any other manner
provided by Law.
