                      SENIOR SUBORDINATED EXCHANGEABLE NOTE

                                                 DUE JUNE 30, 2006

No:  0001                                                    U.S. $54,000,000

         EFTC CORPORATION, a Colorado corporation (the "Company"), for
value received, promises to pay to the order of THAYER-BLUM FUNDING, L.L.C., a
Delaware limited liability company ("Holder"), or its registered successors or
assigns, on June 30, 2006 (or such earlier date as this Note shall become
payable), the principal amount of $54,000,000 (or such lesser or greater
principal amount as is then unpaid) and to pay interest (computed on the basis
of a 360-day year of twelve 30-day months) on the unpaid principal amount hereof
(and on the principal balance of any PIK Note (as defined in Section 10)) at the
rate of 15.00% per annum, compounded quarterly, commencing on the date hereof
for this Note (and on the date of issuance for any PIK Note).

1.       Payment of Principal and Interest.

         The principal of, together with all accrued and unpaid
interest on, this Note shall be due and payable on June 30, 2006. Interest
accruing from the date of issuance through June 30, 2000, shall be added to the
principal amount of this Note on June 30, 2000 or, at the option of the Company,
shall be paid by the issuance of a PIK Note. Thereafter, interest hereon (and on
any PIK Note) shall accrue in arrears on September 30, December 31, March 31 and
June 30 of each year, commencing June 30, 2000, and be added to the principal
amount of this Note or, at the option of the Company, shall be paid by issuance
of a PIK Note, until the principal amount hereof (and the principal amount of
any PIK Note) shall have been paid in full. Notwithstanding the foregoing, if
the Shareholder Approval (as defined in that certain Securities Purchase
Agreement, dated as of March 30, 2000, by and between the Company and Holder
(the "Purchase Agreement")) is not obtained by September 1, 2000 (the "Approval
Date"), then interest on all unpaid amounts outstanding hereunder from and after
such date (or under any PIK Note) (including overdue installments of principal
or interest) shall be payable at the rate of 20.00% per annum, compounded
quarterly (to the extent permitted by applicable law). The Company may treat the
Person in whose name this Note is registered as the owner hereof for the purpose
of receiving payment and for all other purposes. The principal and interest on
this Note (and on any PIK Note) is payable when due in such coin or currency of
the United States of America as at the time of payment is legal tender for
payment of public and private debts by federal funds bank wire transfer. Certain
capitalized terms shall have the meanings specified in Section 10 hereof. This
Note is issued under and pursuant to, and subject to the terms and conditions
of, the Purchase Agreement.

2.       Exchange.

         Upon the consummation of a Successful Tender Offer (as defined
in the Purchase Agreement), the Notes shall automatically be exchanged for and
replaced by 8.875% Senior Subordinated Convertible Notes due June 30, 2006
("Convertible Notes") substantially in the form attached as Exhibit C to the
Purchase Agreement, in an aggregate principal amount equal to the aggregate
principal amount of Notes then outstanding, plus accrued interest.

3.       Optional Redemption.

         If the Shareholder Approval is not obtained on or prior to the
Approval Date, the Company may redeem the Notes, in whole or in part, by paying
a redemption price equal to 108% of the principal amount of the Notes so being
redeemed, plus accrued and unpaid interest to the redemption date. If the
Company elects to repurchase the Warrants issued by the Company on March 30,
2000 pursuant to the Purchase Agreement as provided for in Section 5 of the
Warrants, the Company may redeem this Note, in whole, at a redemption price
equal to 100% of the principal amount thereof, plus accrued and unpaid interest
to the redemption date.

4.       Mandatory Redemption.

         The Company will be obligated to redeem the Notes, at the
option of the Holders of a majority in principal amount of the Notes of the
Holders, in whole or in part, at a redemption price equal to 100% of the
principal amount thereof, plus accrued and unpaid interest to the redemption
date upon a Change of Control or a Financing Redemption Event (each a "Mandatory
Redemption Event").

5.       Redemption Procedures.

         (a) If fewer than all of the principal of and accrued interest on the
Notes are to be redeemed, the Company shall redeem a pro rata portion of each
Note then outstanding.

         (b) At least 30 days but not more than 60 days before a redemption
pursuant to Section 3, the Company shall mail a notice of redemption to each
Holder whose Notes are to be redeemed. The notice shall: (i) identify the Notes
to be redeemed and shall state the redemption date; (ii) state the redemption
price; (iii) indicate, if any Note is being redeemed in part, the portion of the
principal amount of such Note to be redeemed and that, after the redemption
date, upon surrender of such Note, a new Note or Notes in principal amount equal
to the unredeemed portion will be issued; (iv) state that Notes called for
redemption must be surrendered to the Company to collect the redemption price;
and (v) state that interest on the Notes called for redemption ceases to accrue
on and after the redemption date, unless the Company has defaulted on the
payment of the redemption price.

         (c) In the event a Mandatory Redemption Event shall occur, at the sole
option of the Holders of a majority in principal amount of the Notes, Holders
may elect to have the Company mandatorily redeem Notes pursuant to Section 4 by
mailing a notice of such election to the Company within 60 days of the
occurrence of such Mandatory Redemption Event. The notice shall: (i) identify
the Notes to be redeemed and shall state the date upon which the Mandatory
Redemption Event occurred; (ii) state the redemption date (as set forth in
subsection (d)); and (iii) indicate, if any Note is being redeemed in part, the
portion of the principal amount of such Note to be redeemed and that, after the
redemption date, upon surrender of such Note, a new Note or Notes in principal
amount equal to the unredeemed portion will be issued.

         (d) The redemption date with respect to any redemption effected in the
case of a Mandatory Redemption Event shall be a date not earlier than the fifth
day nor later than the 30th day following the receipt by the Company of the
notice thereof pursuant to Section 5(c).

         (e) Once notice of redemption is given, Notes called for redemption
become due and payable on the redemption date at the redemption price.

         (f) Upon surrender of a Note that is redeemed in part, the Company
shall issue a new Note equal in principal amount to the unredeemed portion of
the Note surrendered.

6.       Subordination.

         (a)  Agreement to Subordinate.

              The Company and Holders agree that the indebtedness evidenced by
this Note is subordinated in right of payment, to the extent and in the manner
provided in this Section 6, to the prior payment in full, in cash, of all Senior
Debt (as defined below), (whether outstanding on the date hereof or hereafter
created, incurred, assumed or guaranteed), and that the subordination is for the
benefit of the holders of Senior Debt.

              A distribution may consist of cash, securities or other property,
by set-off or otherwise.

         (b)  Liquidation; Dissolution; Bankruptcy.

              Upon any distribution to creditors of the Company in a liquidation
or dissolution of the Company or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Company or its property, in
an assignment for the benefit of creditors or any marshalling of the Company's
assets and liabilities:

              (i) holders of Senior Debt shall be entitled to receive payment in
full, in cash, of all obligations due in respect of such Senior Debt (including
interest after the commencement of any such proceeding at the rate specified in
the applicable Senior Debt) before any Holder shall be entitled to receive any
payment with respect to its Note (except that Holders may receive Permitted
Junior Securities); and

              (ii) until all obligations with respect to Senior Debt (as
provided in subsection (i) above) are paid in full, in cash, any distribution to
which Holders would be entitled but for this Section 6 shall be made to holders
of Senior Debt (except that Holders may receive Permitted Junior Securities), as
their interests may appear.

         (c)  Default on Senior Debt.

              (i) The Company may not make any payment or distribution to any
Holder in respect of obligations with respect to the Note and may not acquire
from any Holder any loans for cash or property (other than Permitted Junior
Securities) and no Holder may accept or retain any such payments until all
principal and other obligations with respect to the Senior Debt have been paid
in full, in cash, if:

                  (A) a default in the payment of any principal or other
obligations with respect to Senior Debt occurs and is continuing beyond any
applicable grace period in the agreement, indenture or other document governing
such Senior Debt; or

                  (B) a default, other than a payment default, on Senior Debt
occurs and is continuing that permits holders of the Senior Debt to accelerate
its maturity and the Company receives a notice of the default (a "Payment
Blockage Notice"). If the Company and the Holder Representative receive from the
Agent under the Credit Agreement any such Payment Blockage Notice, no subsequent
Payment Blockage Notice shall be effective for purposes of this Section 6(c)
unless and until at least 360 days shall have elapsed since the effectiveness of
the immediately prior Payment Blockage Notice. No nonpayment default that
existed or was continuing on the date of delivery of any Payment Blockage Notice
to the Company shall be, or be made, the basis for a subsequent Payment Blockage
Notice unless such nonpayment default shall have been waived for a period of not
less than 180 days or unless the holder of the Senior Debt was not aware of such
default.

                  The Company may and shall resume payments on and distributions
in respect of the Notes and the Holder may receive and retain the same upon the
earlier of:

                  (1) the date upon which the default is cured or waived, or

                  (2) in the case of a default referred to in Section 6(c)(ii)
hereof, 179 days pass after notice is received if the maturity of such Senior
Debt has not been accelerated, if this Section 6 otherwise permits the payment
or distribution at the time of such payment or distribution.

              (ii) No Holder may take any actions to enforce any of its
available remedies upon the occurrence of a Default or an Event of Default, for
a period of 90 days following the receipt by the Company and the Holder
Representative of a notice from the Agent under the Credit Agreement of any
default with respect to the Senior Debt; provided, that such 90 day period shall
immediately end in the event (x) of a Default under Section 8(a)(i)(G) or (H),
(y) the Senior Debt is accelerated in accordance with its terms, or (z) the
holders of the Senior Debt act to enforce their available remedies upon the
occurrence of a default on the Senior Debt.

         (d)  Acceleration of Securities.

              If the Note is accelerated because of an Event of Default, the
Company shall promptly notify holders of Senior Debt of the acceleration.

         (e)  When Distribution Must Be Paid Over.

              In the event that Holder receives any payment of any obligations
with respect to the Note at a time when such payment is prohibited by Section
6(c) hereof, such payment shall be held by the Holder in trust for the benefit
of, and shall be paid forthwith over and delivered, upon written request, to,
the holders of Senior Debt under the Senior Debt Documents pursuant to which
Senior Debt may have been issued, as their respective interests may appear, for
application to the payment of all obligations with respect to Senior Debt
remaining unpaid to the extent necessary to pay such obligations in full, in
cash, in accordance with their terms, after giving effect to any concurrent
payment or distribution to or for the holders of Senior Debt.

         (f)  Notice by Company.

              The Company shall promptly notify the Holders of any facts known
to the Company that would cause a payment of any obligations with respect to the
Note to violate this Section 6, but failure to give such notice shall not affect
the subordination of the Note to the Senior Debt as provided in this Section 6.

         (g)  Subrogation.

              After all Senior Debt is paid in full, in cash, and until the Note
is paid in full, the Holders shall be subrogated (equally and ratably with all
other indebtedness pari passu with the Note) to the rights of holders of Senior
Debt to receive distributions applicable to Senior Debt and all other rights,
claims and collateral security of the holders of Senior Debt to the extent that
distributions otherwise payable to the Holders have been applied to the payment
of Senior Debt. A distribution made under this Section 6 to holders of Senior
Debt that otherwise would have been made to the Holders is not, as between the
Company, on one hand, and the Holder, on the other hand, a payment by the
Company on Senior Debt.

         (h)  Relative Rights.

              This Section 6 defines the relative rights of the Holders and
holders of Senior Debt. Nothing in this Note shall:

              (a) impair, as between the Company, on one hand, and the Holders,
on the other hand, the obligation of the Company, which is absolute and
unconditional, to pay principal of and interest on the Note in accordance with
its terms;

              (b) affect the  relative  rights of the Holders  and  creditors
of the Company other than their rights in relation to holders of Senior Debt; or

              (c) prevent any lender from exercising its available remedies upon
a Default or Event of Default, subject to the rights of holders of Senior Debt
to receive distributions and payments otherwise payable to the lenders, and
except as set forth in Section 6(c)(ii) above.

              If the Company fails because of this Section 6 to pay
principal of or interest on the Note on the Payment Date, the failure is still a
Default or Event of Default.

         (i)  Subordination May Not Be Impaired by the Company.

              No right of any holder of Senior Debt to enforce the subordination
of the indebtedness evidenced by any loans shall be impaired by any act or
failure to act by the Company or any Holder or by the failure of the Company or
Holders to comply with the terms of this Note.

         (j)  Distribution or Notice to Representative.

              Whenever a distribution is to be made or a notice given to holders
of Senior Debt, the distribution may be made and the notice given to their
representative.

              Upon any payment or distribution of assets of the Company referred
to in this Section 6 the Holders shall be entitled to rely upon any order or
decree made by any court of competent jurisdiction or upon any certificate of
such representative or of the liquidating trustee or agent or other Person
making any distribution to the Holders for the purpose of ascertaining the
Persons entitled to participate in such distribution, the holders of the Senior
Debt and other indebtedness of the Company, the amount thereof or payable
thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Section 6.

         (k)  Authorization to Effect Subordination.

              The Holders authorize and direct the Company to take such action
as may be necessary or appropriate to effectuate the subordination as provided
in this Section 6.

         (l)  Amendments.

              The provisions of this Section 6 shall not be amended or modified
without the written consent of the holders of all Senior Debt.

7.       Covenants.

         The Company covenants and agrees that so long as this Note shall be
outstanding:

         (a)  Payment of Notes; Satisfaction of Obligations.

              (i) The Company shall pay the  principal of and interest on the
Notes on the dates and in the manner provided in the Notes.

              (ii) If there has occurred and is continuing any Event of Default,
defined below, under Sections 8(a)(i)(A) or 8(a)(i)(B) hereof, then to the
extent lawful, the Company shall pay interest (including interest accruing after
the commencement of any proceeding under any Bankruptcy Law) on all unpaid
amounts outstanding under the Notes (including overdue installments of principal
or interest) at a rate of interest equal to the then current rate of interest
plus 2%, compounded quarterly.

              (iii) Subject to performance by all other parties thereto of their
respective obligations thereunder, the Company shall satisfy in all material
respects all of its obligations under the Transaction Documents.

is required to file with the Commission pursuant to Section 13 or 15(d) of the
Exchange Act.

        (c) Compliance Certificate. The Company shall deliver to the Holders,
within 45 days after the end of each fiscal quarter and within 90 days after the
end of each fiscal year of the Company an Officers' Certificate stating that a
review of the activities of the Company and its subsidiaries during the
preceding fiscal quarter or fiscal year has been made with a view to determining
whether the Company has kept, observed, performed and fulfilled its obligations
under this Agreement, and further stating, as to each such officer signing such
certificate, that to his knowledge the Company has kept, observed, performed and
fulfilled each and every covenant contained in this Agreement (or, if a Default
or Event of Default shall have occurred, describing all such Defaults or Events
of Default of which he may have knowledge) and that to his knowledge no event
has occurred and remains in existence by reason of which payments on account of
the principal of or interest, if any, on the Notes in accordance with their
terms are prohibited or if such event has occurred, a description of the event.
So long as not contrary to the then current recommendations of the American
Institute of Certified Public Accountants, the Officers' Certificate
accompanying the fiscal year end financial statements delivered pursuant to this
Section 7 shall be accompanied by a written statement of independent public
accountants (which shall be one of the "Big Five" accounting firms) that in
making the examination necessary for certification of such financial statements
nothing has come to their attention which would lead them to believe that the
Company has violated any provisions of this Note or, if any such violation has
occurred, specifying the nature and period of existence thereof, it being
understood that such accountants shall not be liable directly or indirectly to
any Person for any failure to obtain knowledge of any such violation. The
Company will deliver to the Holders, forthwith upon becoming aware of (i) any
Default or Event of Default or (ii) any event of default under any other loan
agreement, mortgage, indenture or instrument referred to in Section 6, an
Officers' Certificate specifying in reasonable detail such Default, Event of
Default or default and the nature of any remedial or corrective action the
Company proposes to take with respect thereto.

        (d) Stay, Extension and Usury Laws. The Company covenants and agrees
(to the extent that it may lawfully do so) that it will not at any time insist
upon, plead, or in any manner whatsoever claim or take the benefit or advantage
of, any stay, extension or usury law wherever enacted, now or at any time
hereafter enforced, that may affect the covenants or the performance of its
obligations under this Note; and the Company (to the extent it may lawfully do
so) hereby expressly waives all benefit or advantage of any such law, and
covenants that it will not, by resort to any such law, hinder, delay or impede
the execution of any power herein granted to the Holders, but will suffer and
permit the execution of every such power as though no such law has been enacted.

        (e)   Limitation on Restricted Payments.  The Company shall not,
directly or indirectly:

              (i) declare or pay any  dividend  on, or make any  distribution
to the holders (as such) in respect of, any shares of its capital stock.

              (ii) purchase, redeem or otherwise acquire or retire for value any
Equity Interest of the Company or any subsidiary of the Company (other than any
such Equity Interest of a directly or indirectly wholly-owned subsidiary of the
Company) or other Affiliate of the Company;

              (iii) permit any subsidiary of the Company to declare or pay any
dividend on, or make any distribution to the holders (as such) in respect of,
any shares of its capital stock except to the Company or another directly or
indirectly wholly-owned subsidiary of the Company; or

              (iv) permit any subsidiary of the Company to purchase, redeem or
otherwise retire for value any Equity Interests of it, the Company or any
Affiliate the Company (other than any such Equity Interests owned by the Company
or any other directly or indirectly wholly owned subsidiary of the Company).

         (f) Corporate Existence. The Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence and the corporate existence of each of its subsidiaries in accordance
with the respective organizational documents of each of them and the corporate
rights (charter and statutory), licenses and franchises of the Company and its
subsidiaries; provided, however, that the Company shall not be required to
preserve any such right, license or franchise, or corporate existence, if the
Board of Directors of the Company shall determine that the preservation thereof
is no longer desirable in the conduct of the business of the Company and its
subsidiaries taken as a whole and that the loss thereof will not cause a
Material Adverse Effect.

         (g) Taxes. The Company shall, and shall cause its subsidiaries to, pay
prior to delinquency all material taxes, assessments and governmental levies
except as contested in good faith and by appropriate proceedings.

United States real property holding corporation as defined in Section 897(c)(2)
of the Internal Revenue Code of 1986, as amended.

         (i) Limitation on Additional Indebtedness. The Company will not, and

         (j)  Limitation on Transactions With Affiliates.

              (i) Neither the Company nor any of its subsidiaries shall sell,

understanding, loan, advance or guarantee with, or for the benefit of, an
Affiliate of the Company (but specifically excluding for these purposes Holders
and their respective Affiliates) (an "Affiliate Transaction"), except on terms
that are no less favorable to the Company or the relevant subsidiary than those
that could have been obtained in a comparable transaction by the Company or such
subsidiary from an unrelated person; provided, however, that the Company and its
wholly-owned subsidiaries may engage in any sale, lease, transfer, or other
disposition of property among themselves and may enter into any contract,
agreement, understanding, loan, advance or guarantee among themselves.

              (ii) In addition, neither the Company nor any subsidiary may enter
into an Affiliate Transaction or series of related Affiliate Transactions
involving or having a potential value of more than $1,000,000 unless such
transaction has been approved by the holders of at least a majority in principal

however, that the Company and its wholly-owned subsidiaries may engage in any

Permitted Liens.

         (l)  Sale of Assets.

              (i) Neither the Company nor any of its subsidiaries shall, without
the consent of the holders of at least a majority in principal amount of the
Notes, sell, lease, convey or otherwise dispose (whether in one transaction or a
series of transactions) of any assets (including capital stock of any
subsidiaries), other than sales of inventory in the ordinary course of business
(an "Asset Sale"), if the aggregate net proceeds of all Asset Sales during any
fiscal year exceed $2,000,000; excluding payments under the GECC Payment
Agreement.

              (ii) Neither the Company nor any of its subsidiaries shall,
without the consent of the holders of at least a majority in principal amount of
the Notes, enter into any Asset Sale if the consideration paid is less than the
fair market value of such asset; provided, however, that assets with a fair
market value of not greater than $2,000,000 in the aggregate may be sold during
any fiscal year without regard to the foregoing requirement if the amount of
consideration received for such assets is promptly applied to the purchase of
comparable assets.

              (iii) At least 90% of the consideration for each Asset Sale
received by the Company or such subsidiary shall be in the form of cash;
provided, however, that the amount of (A) any liabilities (as shown on the

thereto) of the Company or any subsidiary that are assumed by the transferee of
any such assets or stock sold, leased, conveyed or disposed of and (B) any notes
or other obligations received by the Company or any subsidiary from such
transferee that are immediately converted by the Company or such subsidiary into
cash, shall be deemed to be cash for purposes of this Section 7(l)(iii).

         (m) Ownership of Subsidiaries. Except as permitted by Section 7(l)
above, the Company shall maintain (along with one or more subsidiaries in the
case of an indirect subsidiary) good and valid title to those Equity Interests
of each of its subsidiaries owned by it, free and clear of any Lien other than
Permitted Liens. Notwithstanding the provisions of Section 7(l) above, neither
the Company nor any subsidiary shall dispose of the capital stock of any
subsidiary, if, after giving effect to such disposition, the Company would own
less than a majority of the outstanding economic and voting interests in such
subsidiary or former subsidiary.

        (n) Minimum Performance Target. The Company shall furnish to the Holders
an Officers' Certificate within 90 days after the end of the Company's fiscal
year ending in 2002 (the "2002 EBITDA Notice"), setting forth the Company's
EBITDA for its previous fiscal year. The 2002 EBITDA Notice shall be audited in
accordance with GAAP and the terms of this Note by the Company's independent
auditors which shall be a "Big Five" accounting firm and shall contain a written
statement that, in making the examination necessary for certification of the
2002 EBITDA Notice, nothing has come to their attention which would lead them to
believe that the Company's EBITDA for the fiscal year ending in 2002 is not
correctly stated in the 2002 EBITDA Notice, or, if the EBITDA is incorrectly
stated, the basis of their belief regarding such incorrect statement.

        (o) Limitation on Dividend and Other Payment Restrictions Affecting
Subsidiaries. Except as otherwise provided herein or in the Senior Debt
Documents, the Company will not, and will not permit any subsidiary to, directly
or indirectly, create or otherwise cause or suffer to exist or become effective
any consensual encumbrance or restriction on the ability of any subsidiary of
the Company to (a) pay dividends or make any other distributions on its capital
stock or any other interest or participation in, or measured by, its profits
owned by, or pay any Indebtedness owed to, the Company or a subsidiary of the
Company, (b) make loans or advances to the Company or a subsidiary of the
Company or (c) transfer any of its properties or assets to the Company or to any
subsidiary of the Company, except for such encumbrances or restrictions existing
under or by reason of (i) any restrictions, with respect to a subsidiary of the
Company that is not a subsidiary of the Company on the date hereof, in existence
at the time such Person becomes a subsidiary of the Company; or (ii) any
restrictions existing under any agreement that refinances or replaces the
agreements containing the restrictions in clause (i); provided that the terms

acknowledges that its two designees have been appointed to the Company's Board
of Directors as of the date of the issuance of this Note. The Company agrees to

Default without the notice or passage of time specified in this paragraph), (E)
(other than a Default resulting from the acceleration of any indebtedness
described therein, which Default shall be an Event of Default without the notice
or passage of time specified in this paragraph) or (F) is not an Event of
Default until the Holders of at least 20% in principal amount of the Notes
notify the Company of the Default and the Company does not cure the Default
within 30 days after receipt of the notice. The notice must specify the Default,
demand that it be remedied and state that the notice is a "Notice of Default".

         (b)  Acceleration of Notes.

              (i) If an Event of Default (other than an Event of Default

continuing, the Holders of 20% in principal amount of the Notes, by notice to
the Company, may declare the unpaid principal of and any accrued interest on all
the Notes to be due and payable. Immediately upon such declaration, the
principal and interest shall be due and payable. If an Event of Default
specified in clause (G) or (H) of Section 8(a)(i) occurs, such an amount shall
ipso facto become and be immediately due and payable without any declaration or
other act on the part of any holder. The Holders of at least a majority in
principal amount of the then outstanding Notes by notice to the Company may
rescind an acceleration and its consequences if the rescission would not
conflict with any judgment or decree and if all existing Events of Default have
been cured or waived except nonpayment of principal or interest that has become
due solely because of the acceleration.

              (ii) If an Event of Default specified in clauses (I) or (J) of
Section 8(a)(i) occurs the Company shall pay in full the principal of and
accrued interest on the Notes to the Holders thereof by no later than September

interest on the Notes by September 30, 2003 the Notes shall thereafter be due
and payable and in continuing Default and from and after such date interest on
the Notes shall accrue and be payable at the Default Rate.

         (c)  Other Remedies.

              (i) If an Event of Default occurs and is continuing, holders of
the Notes may pursue any available remedy to collect the payment of principal or
interest on the Notes or to enforce the performance of any provision of the
Notes.

              (ii) A delay or omission by any holder of any Notes in exercising
any right or remedy accruing upon an Event of Default shall not impair the right
or remedy or constitute a waiver of or acquiescence in the Event of Default. All
remedies are cumulative to the extent permitted by law.

              (iii) If an Event of Default occurs and is continuing, the
Company agrees, at the request of the holders of a majority in principal amount
of the Notes, to have two vacancies made on the Board of Directors, to fill such
two vacancies with designees named by such Holders and to take such actions as
are necessary to have such newly appointed directors elected to the Board of
Directors by the shareholders of the Company, including, if necessary, to call a
special meeting of shareholders and to recommend the election of such directors
by the shareholders.

         (d)   Waiver of Past Defaults.

               The holders of at least a majority in principal amount of the
then outstanding Notes by notice to the Company may waive an existing Default or
Event of Default and its consequences except a continuing Default or Event of
Default in the payment of the principal of or interest on any Notes.

         (e)  Rights of Holder to Receive Payment.

              Notwithstanding any other provision of this Agreement, the right
of any Holder of a Note to receive payment of principal and interest on the
Note, on or after the respective due dates expressed in the Note, or to bring
suit for the enforcement of any such payment on or after such respective dates,
shall not be impaired or affected without the consent of the Holder.

         (f)  Undertaking for Costs.

              In any suit for the enforcement of any right or remedy under this
Agreement, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.

9.       Modification of Notes.

         The Notes may be modified without prior notice to any Holder but with
the written consent of the Company and the Holders of a majority in principal
amount of the Notes then outstanding. The Holders of a majority in principal
amount of the Notes then outstanding may waive compliance by the Company with
any provision of the Notes, or give any consent or approval required or provided
for under the terms of the Notes, without prior notice to any Holder. However,
without the consent of each Holder affected, an amendment, supplement or waiver
may not (a) alter the amount of Notes whose Holders must consent to an
amendment, supplement or waiver, (b) alter the rate or the time for payment of
interest on any Note, (c) alter the principal or the maturity of any Note or
