(ii) SPIRE CORPORATION ("Spire"), a Massachusetts corporation, and BANDWIDTH
SEMICONDUCTOR, LLC ("Bandwidth"), a Delaware limited liability company (jointly
and severally, individually and collectively, the "BORROWER"), provides the
terms on which Bank shall lend to Borrower and Borrower shall repay Bank. The
parties agree as follows:

         1    ACCOUNTING AND OTHER TERMS
              --------------------------

         Accounting terms not defined in this Agreement shall be construed
following GAAP. Calculations and determinations must be made following GAAP.
Capitalized terms not otherwise defined in this Agreement shall have the
meanings set forth in Section 13. All other terms contained in this Agreement,
unless otherwise indicated, shall have the meaning provided by the Code to the
extent such terms are defined therein.

         2    LOAN AND TERMS OF PAYMENT
              -------------------------

         2.1  PROMISE TO PAY. Borrower hereby unconditionally promises to pay
Bank the outstanding principal amount of all Credit Extensions and accrued and
unpaid interest thereon as and when due in accordance with this Agreement.

         2.1.1 EQUIPMENT ADVANCES.

              (a) Availability. Subject to the terms and conditions of this
Agreement, during the Draw Period, Bank shall make advances (each, an "EQUIPMENT
ADVANCE" and, collectively, "EQUIPMENT ADVANCES") not exceeding the Equipment
Line. Equipment Advances may only be used to finance Eligible Equipment
purchased within ninety (90) days (determined based upon the applicable invoice
date of such Eligible Equipment) before the date of each Equipment Advance, and
no Equipment Advance may exceed 100% of the total invoice for Eligible
Equipment, excluding taxes, shipping, warranty charges, freight discounts and
installation expenses relating to such Eligible Equipment. Notwithstanding the
foregoing, the initial Equipment Advance (the "INITIAL EQUIPMENT ADVANCE")
hereunder may be used to reimburse Borrower for Eligible Equipment purchased on
or after September 29, 2006. Unless otherwise agreed to by Bank, not more than
25% of the proceeds of the Equipment Line shall be used to finance Other
Equipment. After repayment, no Equipment Advance may be reborrowed.

              (b) Repayment. In addition to the monthly payments of interest, as
set forth in Section 2.2(a) below, the principal amount of each Equipment
Advance is payable in thirty-six (36) consecutive equal monthly payments of
principal beginning on the first Payment Date following the Funding Date of such
Equipment Advance and continuing on each Payment Date thereafter. The final
payment due on the applicable Equipment Line Maturity Date shall include all
outstanding principal and all accrued unpaid interest.

              (c) Prepayment Upon an Event of Loss. Borrower shall bear the risk
of any loss, theft, destruction, or damage of or to the Financed Equipment. If,
during the term of this Agreement, any item of Financed Equipment becomes
obsolete or is lost, stolen, destroyed, damaged beyond repair, rendered
permanently unfit for use, or seized by a governmental authority for any reason
for a period equal to at least the remainder of the term of this Agreement (an
"EVENT OF LOSS"), then, if no Event of Default has occurred or is continuing,
within ten (10) days following such Event of Loss, at Borrower's option,
Borrower shall (i) pay to Bank on account of the Obligations all accrued
interest to the date of the prepayment, plus all outstanding principal owing
with respect to the Financed Equipment subject to the Event of Loss; or (ii)
repair or replace any Financed Equipment subject to an Event of Loss provided
the repaired or replaced Financed Equipment is of equal or like value to the
Financed Equipment subject to an Event of Loss and provided further that Bank
has a first priority perfected security interest in such repaired or replaced
Financed Equipment.

              (d) Mandatory Prepayment Upon an Acceleration. If the Equipment
Advances are accelerated following the occurrence of an Event of Default,
Borrower shall immediately pay to Bank an amount equal to the sum of (i) all
outstanding principal plus accrued and unpaid interest and (ii) all other sums,
if any, that shall have become due and payable, including interest at the
Default Rate with respect to any past due amounts.
<PAGE>
              (e) Permitted Prepayment of Equipment Advances. So long as no
Event of Default has occurred and is continuing, Borrower shall have the option
to prepay all, but not less than all, of the Equipment Advances advanced by Bank
under this Agreement, provided Borrower (i) delivers written notice to Bank of
its election to prepay the Equipment Advances at least thirty (30) days prior to
such prepayment, and (ii) pays, on the date of such prepayment (A) all
outstanding principal plus accrued and unpaid interest and (B) all other sums,
if any, that shall have become due and payable, including interest at the
Default Rate with respect to any past due amounts.

         2.2  PAYMENT OF INTEREST ON THE CREDIT EXTENSIONS.

              (a) Interest Rate. Subject to Section 2.2(b), the principal amount
outstanding for each Equipment Advance shall accrue interest at a floating per
annum rate equal to one half of one percentage point (0.5%) above the Prime
Rate, which interest shall be payable monthly.

              (b) Default Rate. Immediately upon the occurrence and during the
continuance of an Event of Default, Obligations shall bear interest at a rate
per annum which is three percentage points (3.0%) above the rate effective
immediately before the Event of Default (the "DEFAULT RATE"). Payment or
acceptance of the increased interest rate provided in this Section 2.2(b) is not
a permitted alternative to timely payment and shall not constitute a waiver of
any Event of Default or otherwise prejudice or limit any rights or remedies of
Bank.

              (c) Adjustment to Interest Rate. Changes to the interest rate of
any Credit Extension based on changes to the Prime Rate shall be effective on
the effective date of any change to the Prime Rate and to the extent of any such
change.

              (d) 360-Day Year. Interest shall be computed on the basis of a
360-day year for the actual number of days elapsed.

              (e) Debit of Accounts. Bank may debit any of Borrower's deposit
accounts, including the Designated Deposit Account, for principal and interest
payments or any other amounts Borrower owes Bank when due. These debits shall
not constitute a set-off.

              (f) Payments. Unless otherwise provided, interest is payable
monthly on the Payment Date of each month. Payments of principal and/or interest
received after 12:00 noon Eastern time are considered received at the opening of
business on the next Business Day. When a payment is due on a day that is not a
Business Day, the payment is due the next Business Day and additional fees or
interest, as applicable, shall continue to accrue.

         2.3  FEES. Borrower shall pay to Bank:

              (a) Commitment Fee. A fully earned, non-refundable commitment fee
of Seventeen Thousand Five Hundred Dollars ($17,500.00), on the Effective Date,
which fee the parties acknowledge and agree has been paid by the Borrower to the
Bank; and

              (b) Bank Expenses. All Bank Expenses (including reasonable
attorneys' fees and expenses, plus expenses, for documentation and negotiation
of this Agreement) incurred through and after the Effective Date, when due.

              (a) except as otherwise provided in Section 3.4, timely receipt of
an executed Payment/Advance Form;

              (b) the representations and warranties in Section 5 shall be true
in all material respects on the date of the Payment/Advance Form and on the
Funding Date of each Credit Extension; provided, however, that such materiality
qualifier shall not be applicable to any representations and warranties that
already are qualified or modified by materiality in the text thereof; and
provided, further that those representations and warranties expressly referring
to a specific date shall be true, accurate and complete in all material respects
as of such date, and no Default or Event of Default shall have occurred and be
continuing or result from the Credit Extension. Each Credit Extension is

warranties in Section 5 remain true in all material respects; provided, however,
that such materiality qualifier shall not be applicable to any representations

extension in the absence of a required item shall be in Bank's sole discretion.

         4    CREATION OF SECURITY INTEREST
              -----------------------------

         4.1  GRANT OF SECURITY INTEREST. Borrower hereby grants Bank, to secure
the payment and performance in full of all of the Obligations, a continuing
security interest in, and pledges to Bank, the Collateral, wherever located,
whether now owned or hereafter acquired or arising, and all proceeds and
products thereof. Borrower represents, warrants, and covenants that the security
interest granted herein is and shall at all times continue to be a first
priority perfected security interest in the Collateral (subject only to
Permitted Liens that may have superior priority to Bank's Lien under this
Agreement). If Borrower shall acquire a commercial tort claim, Borrower shall
promptly notify Bank in a writing signed by Borrower of the general details
thereof and grant to Bank in such writing a security interest therein and in the
proceeds thereof, all upon the terms of this Agreement, with such writing to be
in form and substance reasonably satisfactory to Bank.

         If this Agreement is terminated, Bank's Lien in the Collateral shall
continue until the Obligations (other than inchoate indemnity obligations) are
repaid in full in cash. Upon payment in full in cash of the Obligations and at
such time as Bank's obligation to make Credit Extensions has terminated, Bank
shall, at Borrower's sole cost and expense, release its Liens in the Collateral
and all rights therein shall revert to Borrower.

         4.2  AUTHORIZATION TO FILE FINANCING STATEMENTS. Borrower hereby
authorizes Bank to file financing statements, without notice to Borrower, with
all appropriate jurisdictions to perfect or protect Bank's interest or rights
hereunder, including a notice that any disposition of the Collateral, by either
Borrower or any other Person, shall be deemed to violate the rights of Bank
under the Code.

         5    REPRESENTATIONS AND WARRANTIES
              ------------------------------

              Borrower represents and warrants as follows:

         5.1  DUE ORGANIZATION AND AUTHORIZATION. Borrower and each of its
Subsidiaries, if any, are duly existing and in good standing, as Registered
Organizations in their respective jurisdictions of formation and are qualified
and licensed to do business and are in good standing in any jurisdiction in
which the conduct of their business or their ownership of property requires that
they be qualified except where the failure to do so could not reasonably be
expected to have a material adverse effect on Borrower's business. In connection
with this Agreement, Borrower has delivered to Bank a completed perfection
certificate signed by Borrower (the "PERFECTION CERTIFICATE"). Borrower
represents and warrants to Bank that (a) Borrower's exact legal name is that
indicated on the Perfection Certificate and on the signature page hereof; (b)
Borrower is an organization of the type and is organized in the jurisdiction set
forth in the Perfection Certificate; (c) the Perfection Certificate accurately
sets forth Borrower's organizational identification number or accurately states
that Borrower has none; (d) the Perfection Certificate accurately sets forth
Borrower's place of business, or, if more than one, its chief executive office
as well as Borrower's mailing address (if different than its chief executive
office); (e) the Perfection Certificate accurately sets forth any changes to the
Borrower's (and each of its predecessors) jurisdiction of formation,
organizational structure or type, or any organizational number assigned by its
jurisdiction in the past five (5) years; and (f) all other information set forth
on the Perfection Certificate pertaining to Borrower and each of its
Subsidiaries is accurate and complete. If Borrower is not now a Registered
Organization but later becomes one, Borrower shall promptly notify Bank of such
occurrence and provide Bank with Borrower's organizational identification
number.

         The execution, delivery and performance of the Loan Documents have been
duly authorized, and do not conflict with Borrower's organizational documents,
nor constitute an event of default under any material agreement by which
Borrower is bound. Borrower is not in default under any agreement to which it is
a party or by which it is bound in which the default could reasonably be
expected to have a material adverse effect on Borrower's business.

         5.2  COLLATERAL. Borrower has good title to, has rights in, and the
power to transfer each item of the Collateral upon which it purports to grant a
Lien hereunder, free and clear of any and all Liens except Permitted Liens.
Borrower has no deposit accounts other than the deposit accounts with Bank, the
deposit accounts, if any, described in the Perfection Certificate delivered to
Bank in connection herewith, or of which Borrower has given Bank notice and
taken such actions as are necessary to give Bank a perfected security interest
therein. The Accounts are bona fide, existing obligations of the Account
Debtors.

         The Collateral is not in the possession of any third party bailee (such
as a warehouse) except as otherwise provided in the Perfection Certificate. None
of the components of the Collateral shall be maintained at locations other than
as provided in the Perfection Certificate or as Borrower has given Bank notice
pursuant to Section 7.2. In the event that Borrower, after the date hereof,
intends to store or otherwise deliver any portion of the Collateral to a

                                       -4-
<PAGE>
bailee, then Borrower will first receive the written consent of Bank and such
bailee must execute and deliver a bailee agreement in form and substance
satisfactory to Bank in its sole discretion.

         All Financed Equipment is new, except for such Financed Equipment that
has been disclosed in writing to Bank by Borrower as "used" and that Bank, in
its sole discretion, has agreed to finance. All Inventory is in all material
respects of good and marketable quality, free from material defects.

         Except as noted on the Perfection Certificate, Borrower is not a party
to, nor is bound by, any material license or other agreement with respect to
which Borrower is the licensee that prohibits or otherwise restricts Borrower
from granting a security interest in Borrower's interest in such license or
agreement or any other property. Borrower shall provide written notice to Bank
within ten (10) days of entering or becoming bound by any such license or
agreement which is reasonably likely to have a material impact on Borrower's
business or financial condition (other than over-the-counter software that is
commercially available to the public). Borrower shall take such steps as Bank
requests to obtain the consent of, or waiver by, any person whose consent or
waiver is necessary for all such licenses or contract rights to be deemed
"Collateral" and for Bank to have a security interest in it that might otherwise
be restricted or prohibited by law or by the terms of any such license or
agreement (such consent or authorization may include a licensor's agreement to a
contingent assignment of the license to Bank if Bank determines that is
necessary in its good faith judgment), whether now existing or entered into in
the future.

         5.3  LITIGATION. Except as set forth on SCHEDULE 5.3 attached hereto,
there are no actions or proceedings pending or, to the knowledge of the
Responsible Officers, threatened in writing by or against Borrower or any of its
Subsidiaries involving more than One Hundred Thousand Dollars ($100,000.00).

         5.4  NO MATERIAL DETERIORATION IN FINANCIAL STATEMENTS. All
consolidated financial statements for Borrower and any of its Subsidiaries
delivered to Bank fairly present in all material respects Borrower's
consolidated financial condition and Borrower's consolidated results of
operations. There has not been any material deterioration in Borrower's
consolidated financial condition since the date of the most recent financial
statements submitted to Bank.

         5.5  SOLVENCY. The fair salable value of Borrower's assets (including
goodwill minus disposition costs) exceeds the fair value of its liabilities;
Borrower is not left with unreasonably small capital after the transactions in
this Agreement; and Borrower is able to pay its debts (including trade debts) as
they mature.

         5.6  REGULATORY COMPLIANCE. Borrower is not an "investment company" or
a company "controlled" by an "investment company" under the Investment Company
Act of 1940. Borrower is not engaged as one of its important activities in
extending credit for margin stock (under Regulations T and U of the Federal
Reserve Board of Governors). Borrower has complied in all material respects with
the Federal Fair Labor Standards Act. Borrower has not violated any laws,
ordinances or rules, the violation of which could reasonably be expected to have
a material adverse effect on its business. None of Borrower's or any of its
Subsidiaries' properties or assets has been used by Borrower or any Subsidiary
or, to the best of Borrower's knowledge, by previous Persons, in disposing,
producing, storing, treating, or transporting any hazardous substance other than
legally. Borrower and each of its Subsidiaries have obtained all consents,
approvals and authorizations of, made all declarations or filings with, and
given all notices to, all government authorities that are necessary to continue
its business as currently conducted.

         5.7  SUBSIDIARIES; INVESTMENTS. Borrower does not own any stock,
partnership interest or other equity securities except for Permitted
Investments.

         5.8  TAX RETURNS AND PAYMENTS; PENSION CONTRIBUTIONS. Borrower has
timely filed all required tax returns and reports, and Borrower and its
Subsidiaries have timely paid all foreign, federal, state and local taxes,
assessments, deposits and contributions owed by Borrower. Borrower may defer
payment of any contested taxes, provided that Borrower (a) in good faith
contests its obligation to pay the taxes by appropriate proceedings promptly and
diligently instituted and conducted, (b) notifies Bank in writing of the
commencement of, and any material development in, the proceedings, (c) posts
bonds or takes any other steps required to prevent the governmental authority
levying such contested taxes from obtaining a Lien upon any of the Collateral
that is other than a "Permitted Lien". Borrower is unaware of any claims or
adjustments proposed for any of Borrower's prior tax years which could result in
additional taxes becoming due and payable by Borrower. Borrower has paid all
amounts necessary to fund all present pension, profit sharing and deferred
compensation plans in accordance with their terms, and Borrower has not
withdrawn from participation in, and has not permitted partial or complete
termination of, or permitted the occurrence of any other event with respect to,
any such plan which could reasonably be expected to

                                       -5-
<PAGE>
result in any liability of Borrower, including any liability to the Pension
Benefit Guaranty Corporation or its successors or any other governmental agency.

         5.9  USE OF PROCEEDS. Borrower shall use the proceeds of the Credit
Extensions solely to purchase Eligible Equipment and to fund its general
business requirements and not for personal, family, household or agricultural
purposes.

         5.10 FULL DISCLOSURE. No written representation, warranty or other
statement of Borrower in any certificate or written statement given to Bank, as
of the date such representations, warranties, or other statements were made,
taken together with all such written certificates and written statements given
to Bank, contains any untrue statement of a material fact or omits to state a
material fact necessary to make the statements contained in the certificates or
statements not misleading (it being recognized by Bank that the projections and
forecasts provided by Borrower in good faith and based upon reasonable
assumptions are not viewed as facts and that actual results during the period or
periods covered by such projections and forecasts may differ from the projected
or forecasted results).

         6    AFFIRMATIVE COVENANTS
              ---------------------

         Borrower shall do all of the following:

         6.1  GOVERNMENT COMPLIANCE. Maintain its and all its Subsidiaries'
legal existence and good standing in their respective jurisdictions of formation
and maintain qualification in each jurisdiction in which the failure to so
qualify would reasonably be expected to have a material adverse effect on
Borrower's business or operations. Borrower shall comply, and have each
Subsidiary comply, with all laws, ordinances and regulations to which it is
subject, the noncompliance with which could have a material adverse effect on
Borrower's business.

         6.2  FINANCIAL STATEMENTS, REPORTS, CERTIFICATES.

              (a) Deliver to Bank: (i) as soon as available, but no later than

operations during the period certified by a Responsible Officer and in a form
acceptable to Bank; (ii) as soon as available, but no later than one hundred
fifty (150) days after the last day of Borrower's fiscal year, audited

reasonable discretion; (iii) within five (5) days of delivery, copies of all

Borrower's or another website on the Internet; (v) a prompt report of any legal
actions pending or threatened against Borrower or any of its Subsidiaries that

forty-five (45) days of Board approval, annual budget and financial projections
with any material changes; and (vii) other financial information reasonably
requested by Bank.

deliver to Bank with the monthly financial statements, a duly completed
Compliance Certificate signed by a Responsible Officer setting forth
calculations showing compliance with the financial covenants set forth in this
Agreement.

         6.3  INVENTORY; RETURNS. Keep all Inventory in good and marketable
condition, free from material defects. Returns and allowances between Borrower
and its Account Debtors shall follow Borrower's customary practices as they
exist at the Effective Date. Borrower must promptly notify Bank of all returns,
recoveries, disputes and claims that involve more than Two Hundred Fifty
Thousand Dollars ($250,000).

         6.4  TAXES; PENSIONS. Make, and cause each of its Subsidiaries to make,
timely payment of all foreign, federal, state, and local taxes or assessments
(other than taxes and assessments which Borrower is contesting pursuant to the
terms of Section 5.8 hereof) and shall deliver to Bank, on demand, appropriate
certificates attesting to such payments, and pay all amounts necessary to fund
all present pension, profit sharing and deferred compensation plans in
accordance with their terms.

                                       -6-
<PAGE>
         6.5  INSURANCE. Keep its business and the Collateral insured for risks
and in amounts standard for companies in Borrower's industry and location and as
Bank may reasonably request. Insurance policies shall be in a form, with
companies, and in amounts that are satisfactory to Bank. All property policies
shall have a lender's loss payable endorsement showing Bank as lender loss payee
and waive subrogation against Bank, and all liability policies shall show, or
have endorsements showing, Bank as an additional insured. All policies (or the
loss payable and additional insured endorsements) shall provide that the insurer
must give Bank at least twenty (20) days notice before canceling, amending, or
declining to renew its policy. At Bank's request, Borrower shall deliver
certified copies of policies and evidence of all premium payments. Proceeds
payable under any policy shall, at Bank's option, be payable to Bank on account
of the Obligations. Notwithstanding the foregoing, (a) so long as no Event of
Default has occurred and is continuing, Borrower shall have the option of
applying the proceeds of any casualty policy up to $250,000 with respect to any
loss, but not exceeding $500,000, in the aggregate for all losses under all
casualty policies in any one year, toward the replacement or repair of destroyed
or damaged property; provided that any such replaced or repaired property (i)
shall be of equal or like value as the replaced or repaired Collateral and (ii)
shall be deemed Collateral in which Bank has been granted a first priority
security interest, and (b)after the occurrence and during the continuance of an
Event of Default, all proceeds payable under such casualty policy shall, at the
option of Bank, be payable to Bank on account of the Obligations. If Borrower
fails to obtain insurance as required under this Section 6.5 or to pay any
amount or furnish any required proof of payment to third persons and Bank, Bank
may make all or part of such payment or obtain such insurance policies required
in this Section 6.5, and take any action under the policies Bank deems prudent.

         6.6  OPERATING ACCOUNTS.

              (a) Borrower and its Subsidiaries shall maintain their domestic
depository accounts (with the exception of petty cash deposit accounts, as set
forth on SCHEDULE 6.6, provided that the maximum aggregate balance of such
accounts do not exceed Fifty Thousand Dollars ($50,000.00), in the aggregate, at
any time, and a Citizens Bank Savings Account No. 1165-123685 up to Three
Hundred Thousand Dollars ($300,000.00) to secure reimbursement obligations under
letters of credit, collectively, the "PERMITTED ACCOUNTS") and securities
accounts (with the exception of Borrower's Citibank Securities Account) with
Bank and Bank's affiliates. In addition to the foregoing, within ninety (90)
days after the Effective Date, Borrower shall maintain its and its Subsidiaries'
operating accounts with Bank and Bank's affiliates.

              (b) Provide Bank five (5) days prior written notice before
establishing any Collateral Account at or with any bank or financial institution
other than Bank or its Affiliates. In addition, for each Collateral Account that
Borrower at any time maintains (with the exception of the Permitted Accounts),
Borrower shall cause the applicable bank or financial institution (other than
Bank) at or with which any Collateral Account is maintained to execute and
deliver a Control Agreement or other appropriate instrument with respect to such
Collateral Account to perfect Bank's Lien in such Collateral Account in
accordance with the terms hereunder. The provisions of the previous sentence
shall not apply to deposit accounts exclusively used for payroll, payroll taxes
and other employee wage and benefit payments to or for the benefit of Borrower's
employees and identified to Bank by Borrower as such.

         6.7  FINANCIAL COVENANTS.

              Borrower shall maintain, at all times, to be tested as of the last
day of each month, unless otherwise noted, on a consolidated basis:

1.0 to 1.0 as of the last day of each of the months ending May 31, 2007, and
June 30, 2007; and (ii) 1.5 to 1.0 as of the last day of the month ending July
31, 2007, and as of the last day of each month thereafter. Notwithstanding the
foregoing, the failure of Borrower to comply with this financial covenant during
any such month shall not constitute an Event of Default provided that: (a)
during any quarter in which Borrower maintains Net Income (tested as of the last
day of each quarter) of less then One Dollar ($1.00), Borrower's Unrestricted
Cash is greater than or equal to one and one-quarter times (1.25x) the
outstanding principal amount of the Equipment Line at all times during such
month, or (b) during any quarter in which Borrower maintains Net Income (tested
as of the last day of each quarter) of at least One Dollar ($1.00), Borrower's
Unrestricted Cash is greater than or equal to one times (1.0x) the principal
amount of the outstanding Equipment Line at all times during such month.

              (b) Minimum Quarterly Net Income. Borrower shall maintain Net
Income of at least: (i) ($1,500,000.00) as of the last day of the quarter

                                       -7-
<PAGE>
ending June 30, 2007, (ii) $1.00 as of the last day of the quarter ending
September 30, 2007, and (iii) $250,000.00 as of the last day of the quarter
ending December 31, 2007, and as of the last day of each quarter thereafter.

         6.8  INTENTIONALLY DELETED.

         6.9  LITIGATION COOPERATION. From the date hereof and continuing
through the termination of this Agreement, make available to Bank, without
expense to Bank, Borrower and its officers, employees and agents and Borrower's
books and records, to the extent that Bank may deem them reasonably necessary to
prosecute or defend any third-party suit or proceeding instituted by or against
Bank with respect to any Collateral or relating to Borrower.

         6.10 FURTHER ASSURANCES. Execute any further instruments and take
further action as Bank reasonably requests to perfect or continue Bank's Lien in
the Collateral or to effect the purposes of this Agreement.

         7    NEGATIVE COVENANTS

Subordinated Debt, except under the terms of the subordination, intercreditor,

         8    EVENTS OF DEFAULT
              -----------------

         Any one of the following shall constitute an event of default (an
"EVENT OF DEFAULT") under this Agreement:

         8.1  PAYMENT DEFAULT. Borrower fails to (a) make any payment of
principal or interest on any Credit Extension on its due date, or (b) pay any
other Obligations within three (3) Business Days after such Obligations are due
and payable (which three (3) Business Day grace period will not apply to
payments due on the Equipment Line Maturity Date). During the cure period, the
failure to cure the payment default is not an Event of Default (but no Credit
Extension will be made during the cure period);

         8.2  COVENANT DEFAULT.

              (a) Borrower fails or neglects to perform any obligation in
Sections 6.2, 6.5, 6.6, 6.7, or violates any covenant in Section 7; or

              (b) Borrower fails or neglects to perform, keep, or observe any
other term, provision, condition, covenant or agreement contained in this
Agreement, any Loan Documents, and as to any default (other than those specified
in this Section 8) under such other term, provision, condition, covenant or
agreement that can be cured, has failed to cure the default within ten (10) days
after the occurrence thereof; provided, however, that if the default cannot by
its nature be cured within the ten (10) day period or cannot after diligent
attempts by Borrower be cured within such ten (10) day period, and such default
is likely to be cured within a reasonable time, then Borrower shall have an
additional period (which shall not in any case exceed thirty (30) days) to
attempt to cure such default, and within such reasonable time period the failure
to cure the default shall not be deemed an Event of Default (but no Credit
Extensions shall be made during such cure period). Grace periods provided under
this Section shall not apply, among other things, to financial covenants or any
other covenants set forth in subsection (a) above;

         8.3  MATERIAL ADVERSE CHANGE.  A Material Adverse Change occurs;

         8.4  ATTACHMENT. (a) Any material portion of Borrower's assets is
attached, seized, levied on, or comes into possession of a trustee or receiver
and the attachment, seizure or levy is not removed in ten (10) days; (b) the
service of process seeking to attach, by trustee or similar process, any funds
of Borrower, or of any entity under control of Borrower (including a
Subsidiary), on deposit with Bank or Bank's Affiliate; (c) Borrower is enjoined,
restrained, or prevented by court order from conducting a material part of its
business; (d) a judgment or other claim in excess of Five Hundred Thousand
Dollars ($500,000) becomes a Lien on any of Borrower's assets; or (e) a notice
of lien, levy, or assessment is filed against any of Borrower's assets by any
government agency and not paid within ten (10) days after Borrower receives
notice. These are not Events of Default if stayed or if a bond is posted pending
contest by Borrower (but no Credit Extensions shall be made during the cure
period);

                                       -9-
<PAGE>
         8.5  INSOLVENCY (a) Borrower is unable to pay its debts (including
trade debts) as they become due or otherwise becomes insolvent; (b) Borrower
begins an Insolvency Proceeding; or (c) an Insolvency Proceeding is begun
against Borrower and not dismissed or stayed within forty-five (45) days (but no
Credit Extensions shall be made while of any of the conditions described in
clause (a) exist and/or until any Insolvency Proceeding is dismissed);

         8.6  OTHER AGREEMENTS. There is a default in any agreement to which
Borrower or any Guarantor is a party with a third party or parties resulting in
a right by such third party or parties, whether or not exercised, to accelerate
the maturity of any Indebtedness in an amount in excess of Fifty Thousand
Dollars ($50,000) or that could have a material adverse effect on Borrower's
business;

         8.7  JUDGMENTS. A judgment or judgments for the payment of money in an
amount, individually or in the aggregate, of at least Fifty Thousand Dollars
($50,000) (not covered by independent third-party insurance) shall be rendered
against Borrower and shall remain unsatisfied and unstayed for a period of ten
(10) days after the entry thereof (provided that no Credit Extensions will be
made prior to the satisfaction or stay of such judgment);

         8.8  MISREPRESENTATIONS. Borrower or any Person acting for Borrower
makes any representation, warranty, or other statement now or later in this
Agreement, any Loan Document or in any writing delivered to Bank or to induce
Bank to enter this Agreement or any Loan Document, and such representation,
warranty, or other statement is incorrect in any material respect when made;

         8.9  SUBORDINATED DEBT. A default or breach occurs under any agreement
between Borrower and any creditor of Borrower that signed a subordination,
intercreditor, or other similar agreement with Bank, or any creditor that has
signed such an agreement with Bank breaches any terms of such agreement; or

         9    BANK'S RIGHTS AND REMEDIES
              --------------------------

         9.1  RIGHTS AND REMEDIES. While an Event of Default occurs and
continues Bank may, without notice or demand, do any or all of the following:

              (a) declare all Obligations immediately due and payable (but if an
Event of Default described in Section 8.5 occurs all Obligations are immediately
due and payable without any action by Bank);

              (b) stop advancing money or extending credit for Borrower's
benefit under this Agreement or under any other agreement between Borrower and
Bank;

              (c) demand that Borrower (i) deposits cash with Bank in an amount
equal to the aggregate amount of any letters of credit remaining undrawn, as
collateral security for the repayment of any future drawings under such letters
of credit, and Borrower shall forthwith deposit and pay such amounts, and (ii)
pay in advance all letter of credit fees scheduled to be paid or payable over
the remaining term of any letters of credit;

              (d) settle or adjust disputes and claims directly with Account
Debtors for amounts on terms and in any order that Bank considers advisable,
notify any Person owing Borrower money of Bank's security interest in such
funds, and verify the amount of such account;

              (e) make any payments and do any acts it considers necessary or
reasonable to protect the Collateral and/or its security interest in the
Collateral. Borrower shall assemble the Collateral if Bank requests and make it
available as Bank designates. Bank may enter premises where the Collateral is
located, take and maintain possession of any part of the Collateral, and pay,
purchase, contest, or compromise any Lien which appears to be prior or superior
to its security interest and pay all expenses incurred. Borrower grants Bank a
license to enter and occupy any of its premises, without charge, to exercise any
of Bank's rights or remedies;

              (f) apply to the Obligations any (i) balances and deposits of
Borrower it holds, or (ii) any amount held by Bank owing to or for the credit or
the account of Borrower;

              (g) ship, reclaim, recover, store, finish, maintain, repair,
prepare for sale, advertise for sale, and sell the Collateral. Bank is hereby
granted a non-exclusive, royalty-free license or other right to use, without
charge, Borrower's labels, patents, copyrights, mask works, rights of use of any
name, trade secrets, trade names, trademarks, service marks, and advertising
matter, or any similar property as it pertains to the Collateral, in

                                      -10-
<PAGE>
completing production of, advertising for sale, and selling any Collateral and,
in connection with Bank's exercise of its rights under this Section, Borrower's
rights under all licenses and all franchise agreements inure to Bank's benefit;

              (h) place a "hold" on any account maintained with Bank and/or
deliver a notice of exclusive control, any entitlement order, or other
directions or instructions pursuant to any Control Agreement or similar
agreements providing control of any Collateral;

              (i) demand and receive possession of Borrower's Books; and

              (j) exercise all rights and remedies available to Bank under the
Loan Documents or at law or equity, including all remedies provided under the
Code (including disposal of the Collateral pursuant to the terms thereof).

         9.2  POWER OF ATTORNEY. Borrower hereby irrevocably appoints Bank as
its lawful attorney-in-fact, exercisable upon the occurrence and during the
continuance of an Event of Default, to: (a) endorse Borrower's name on any
checks or other forms of payment or security; (b) sign Borrower's name on any
invoice or bill of lading for any Account or drafts against Account Debtors; (c)
settle and adjust disputes and claims about the Accounts directly with Account
Debtors, for amounts and on terms Bank determines reasonable; (d) make, settle,
and adjust all claims under Borrower's insurance policies; (e) pay, contest or
settle any Lien, charge, encumbrance, security interest, and adverse claim in or
to the Collateral, or any judgment based thereon, or otherwise take any action
to terminate or discharge the same; and (f) transfer the Collateral into the
name of Bank or a third party as the Code permits. Borrower hereby appoints Bank
as its lawful attorney-in-fact to sign Borrower's name on any documents
necessary to perfect or continue the perfection of Bank's security interest in
the Collateral regardless of whether an Event of Default has occurred until all
Obligations have been satisfied in full and Bank is under no further obligation
to make Credit Extensions hereunder. Bank's foregoing appointment as Borrower's
attorney in fact, and all of Bank's rights and powers, coupled with an interest,
are irrevocable until all Obligations have been fully repaid and performed and
Bank's obligation to provide Credit Extensions terminates.

         9.3  ACCOUNTS VERIFICATION; COLLECTION. Whether or not an Event of
Default has occurred and is continuing, Bank may notify any Person owing
Borrower money of Bank's security interest in such funds and verify the amount
of such account. After the occurrence of an Event of Default, any amounts
received by Borrower shall be held in trust by Borrower for Bank, and, if
requested by Bank, Borrower shall immediately deliver such receipts to Bank in
the form received from the Account Debtor, with proper endorsements for deposit.

         9.4  PROTECTIVE PAYMENTS. If Borrower fails to obtain the insurance
called for by Section 6.5 or fails to pay any premium thereon or fails to pay
any other amount which Borrower is obligated to pay under this Agreement or any
other Loan Document, Bank may obtain such insurance or make such payment, and
all amounts so paid by Bank are Bank Expenses and immediately due and payable,
bearing interest at the then highest applicable rate charged by Bank, and
secured by the Collateral. Bank will make reasonable efforts to provide Borrower
with notice of Bank obtaining such insurance at the time it is obtained or
within a reasonable time thereafter. No payments by Bank are deemed an agreement
to make similar payments in the future or Bank's waiver of any Event of Default.

         9.5  APPLICATION OF PAYMENTS AND PROCEEDS. If an Event of Default has
occurred and is continuing, Bank may apply any funds in its possession, whether
from Borrower account balances, payments, proceeds realized as the result of any
collection of Accounts or other disposition of the Collateral, or otherwise, to
the Obligations in such order as Bank shall determine in its sole discretion.
Any surplus shall be paid to Borrower or other Persons legally entitled thereto;
Borrower shall remain liable to Bank for any deficiency. If Bank, in its good
faith business judgment, directly or indirectly enters into a deferred payment
or other credit transaction with any purchaser at any sale of Collateral, Bank
shall have the option, exercisable at any time, of either reducing the
Obligations by the principal amount of the purchase price or deferring the
reduction of the Obligations until the actual receipt by Bank of cash therefor.

         9.6  BANK'S LIABILITY FOR COLLATERAL. So long as Bank complies with
reasonable banking practices regarding the safekeeping of the Collateral in the
possession or under the control of Bank, Bank shall not be liable or responsible
for: (a) the safekeeping of the Collateral; (b) any loss or damage to the
Collateral; (c) any diminution in the value of the Collateral; or (d) any act or
default of any carrier, warehouseman, bailee, or other Person. Borrower bears
all risk of loss, damage or destruction of the Collateral.

                                      -11-
<PAGE>
         9.7  NO WAIVER; REMEDIES CUMULATIVE. Bank's failure, at any time or
times, to require strict performance by Borrower of any provision of this
Agreement or any other Loan Document shall not waive, affect, or diminish any
right of Bank thereafter to demand strict performance and compliance herewith or
therewith. No waiver hereunder shall be effective unless signed by Bank and then
is only effective for the specific instance and purpose for which it is given.
Bank's rights and remedies under this Agreement and the other Loan Documents are
cumulative. Bank has all rights and remedies provided under the Code, by law, or
in equity. Bank's exercise of one right or remedy is not an election, and Bank's
waiver of any Event of Default is not a continuing waiver. Bank's delay in
exercising any remedy is not a waiver, election, or acquiescence.

         9.8  DEMAND WAIVER. Borrower waives demand, notice of default or
dishonor, notice of payment and nonpayment, notice of any default, nonpayment at
maturity, release, compromise, settlement, extension, or renewal of accounts,
documents, instruments, chattel paper, and guarantees held by Bank on which
Borrower is liable.

         11   CHOICE OF LAW, VENUE AND JURY TRIAL WAIVER
              ------------------------------------------

         Massachusetts law governs the Loan Documents without regard to
principles of conflicts of law. Borrower and Bank each submit to the exclusive
jurisdiction of the State and Federal courts in Massachusetts; provided,
however, that if for any reason Bank cannot avail itself of such courts in the
Commonwealth of Massachusetts, Borrower accepts jurisdiction of the courts and
venue in Santa Clara County, California. NOTWITHSTANDING THE FOREGOING, BANK
SHALL HAVE THE RIGHT TO BRING ANY ACTION OR PROCEEDING AGAINST BORROWER OR ITS
PROPERTY IN THE COURTS OF ANY OTHER JURISDICTION WHICH BANK DEEMS NECESSARY OR
APPROPRIATE IN ORDER TO REALIZE ON THE COLLATERAL OR TO OTHERWISE ENFORCE BANK'S
RIGHTS AGAINST BORROWER OR ITS PROPERTY.

TO THE EXTENT PERMITTED BY APPLICABLE LAW, BORROWER AND BANK EACH WAIVE THEIR
RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED
UPON THIS AGREEMENT, THE LOAN DOCUMENTS OR ANY CONTEMPLATED TRANSACTION,
INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS WAIVER IS A
MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS AGREEMENT. EACH PARTY
HAS REVIEWED THIS WAIVER WITH ITS COUNSEL.

         12   GENERAL PROVISIONS
              ------------------

         12.1 Successors and Assigns. This Agreement binds and is for the
benefit of the successors and permitted assigns of each party. Borrower may not
assign this Agreement or any rights or obligations under it without Bank's prior
written consent (which may be granted or withheld in Bank's discretion). Bank
has the right, without the consent of or notice to Borrower, to sell, transfer,

                                   LITIGATION
                                   ----------

     Spire was named a defendant in 58 cases filed from August 2001 to July 2003
in various state courts in Texas by persons claiming damages from the use of
allegedly defective mechanical heart valves coated by a process licensed by
Spire to St. Jude Medical, Inc., the heart valve manufacturer, which has also
been named as a defendant in these cases. In June 2003, a motion for summary
judgment was granted to Spire and most of these cases were dismissed, based on
the principle of federal preemption. The Texas Court of Appeals upheld the lower
court's decision, and, because these cases were not submitted for review to the
Texas Supreme Court, the judgments rendered are now final.

     As of January 2007, four cases remain pending in various district courts in
Harris County, Texas. One of these cases appears to remain pending despite its
inclusion in the original summary judgment which was subsequently upheld by the
first court of appeals. This may be the result of an administrative omission;
counsel for Spire intends to confirm with the court that this case should in
fact no longer be pending. Two of the remaining cases where filed after the
motion for summary judgment, but since the appeals court has subsequently ruled
in Spire's favor, counsel for Spire is asking the plaintiffs in these cases to
consider voluntary dismissal, or alternatively, because the cases are not
actively prosecuted, to ask the court to dismiss them. The remaining case was
not subject to the preemption argument advanced by Spire's counsel and either
may be settled or may go to trial.

     During the second quarter of 2005 a suit was filed by Arrow International,
Inc. against Spire Biomedical, Inc., a wholly owned subsidiary of Spire,
alleging patent infringement by Spire. The complaint claims one of Spire's
catheter products induces and contributes to infringement when medical
professionals insert it. Spire has responded to the complaint denying all
allegations and has filed certain counterclaims. The discovery process in this
case has continued and is nearly complete. Spire filed a motion for summary
judgment, asserting patent invalidity resulting from plaintiff's failure to
follow the administrative procedures of the U.S. Patent and Trademark Office
("USPTO") which failure has remained uncorrected. On August 4, 2006, the Court
granted Spire's motion and dismissed this lawsuit without prejudice. Plaintiffs
applied to revive the applicable patent, which application was granted by the
USPTO in August 2006. Plaintiffs refiled their lawsuit against Spire in
September 2006. Spire has filed its answer and resumed its defense. The parties
have been working to conclude discovery. At this time, however, in response to a
joint request, the court has temporarily stayed the proceedings to allow the
parties to discuss possible alternative methods toward resolution of the subject
matter of the litigation. Based on information presently available to Spire,
Spire believes that it does not infringe any valid claim of the plaintiff's
patent and that, consequently, it has meritorious legal defenses with respect to
this action in the event it were to be reinstated.

     In an amended complaint filed on December 28, 2006, in the Eastern Division
of the U.S. District Court for the Southern District of Ohio, the wife and
executor of the estate of Darrell Adams, deceased, alleges that the failure of a
hemodialysis catheter manufactured by Spire was a cause of his death. Counsel
retained by its insurance underwriters, on behalf of Spire, have filed an answer
denying all such allegations and asserting various defenses. Based on the
knowledge available to it at this time, Spire determined the likelihood of an
unfavorable outcome to be remote and accordingly has not recorded an accrued
expense.

              The
                Executive’s employment with the Company is hereby terminated as of August
                8, 2007 (the “Termination Date”).  The Company will, in

                to seven (7) month’s salary, in the amount of $96,250, paid in
                installments, at such intervals as the Company regularly makes payments
                to
                employees generally, over such seven (7) month period (the “Severance
                Period”).  Executive shall also be eligible to receive a
                bonus (the “Bonus”) pursuant to the terms of paragraph 3(c) of the
                Employment Agreement in the amount of $37,125.  The Severance

                practicable following (i) Executive’s execution and delivery of this
                Agreement in accordance with the terms of Section 20 below and (ii)
                the
                expiration of the 7-day revocation period provided for in Section
                20 below
                without Executive revoking this Agreement pursuant to the terms
                thereof.  Executive understands and agrees that the Company will
                deduct from the Severance and Bonus all federal, state and/or local
                withholding taxes and other deductions the Company is required by
                law to
                make from its wage payments to employees.  The Executive hereby
                resigns, effective the Termination Date, as the Executive Chairman
                and as
                a Director of the Company and from each and every other position
                he may
                hold at the Company and its affiliates.  In the event that the
                Executive fails to comply with any
                material

    provision
      of this Agreement, the Severance payments hereunder shall be immediately
      cancelled, if the Company has provided written notice to the Executive and

      cure.

     

    
      	
              (b)  

            	
              The
                Company agrees that all of the Executive’s vested stock options may be
                exercised by the Executive after the Effective Date in accordance
                with the
                terms of the Executive’s Employment Agreement (the “Option Expiration
                Date”).  After the Option Expiration Date, all of the
                Executive’s unexercised stock options shall be
                cancelled.

            

    

     

    
      	
              (c)  

            	
              The
                Company agrees that all of the Executive’s unvested shares of restricted
                common stock as of the Effective Date shall continue to vest in accordance
                with the terms and conditions contained in the Employment
                Agreement.  The then unvested shares of restricted common stock
                shall be forfeited if the Executive breaches any of the terms and
                conditions of this Agreement.

            

    

     

    
      	
              2.  

            	
              Consideration.  Except
                as specifically provided in this Agreement, the Employment Agreement
                is
                hereby cancelled and terminated and none of the parties thereto shall
                have
                any obligations to each other under the Employment Agreement, except
                as
                set forth in this Agreement.  Executive hereby acknowledges and
                agrees that the provisions of the Employment Agreement relating to
                any
                severance payments that Executive would be entitled to receive thereunder
                are cancelled and hereby terminated, and that except as provided
                in this
                Agreement, Executive has no legal or other entitlement to the arrangements
                described in the Employment Agreement, and that the Company’s agreement to
                make such payments and provide the other consideration specified
                in this
                Agreement, is sufficient consideration for the general release,
                non-solicitation and non-competition terms set forth respectively
                in this
                Agreement.

            

    

     

    
      	
              3.  

            	
              No
                Other Payments.  The Executive acknowledges that, as of the
                date hereof, the Company has made or has agreed in this Agreement
                to make
                all payments to the Executive as required under the Employment Agreement
                or otherwise for wages that the Executive has earned through the
                Termination Date hereof including bonuses, if any; and has reimbursed
                the
                Executive for all expenses he incurred on behalf of the Company to
                the
                date hereof (except for company expenses from May through the Effective
                Date to be reimbursed in a timely manner) and was entitled to be
                reimbursed for; and, except as provided in this Agreement, the Company
                currently owes him no other payments of any kind and of any
                nature.  Without limiting the generality of the foregoing,
                except as provided in this Agreement, the Executive hereby relinquishes
                any and all right he may have under the Employment Agreement to receive
                cash payments, benefits, shares and options including, without limitation,
                under the provisions of Sections 3(a), (b), (c), (d), (e) and (f)
                of the
                Employment Agreement.

              Except
                for the obligations undertaken by the Company under this Agreement,
                Executive hereby covenants and agrees and releases the Company, and
                all of
                its respective Affiliates (as defined below), and their respective

                claims
                of every kind, nature and description whatsoever (collectively,
                “Claims”) the Executive (or Executive’s respective successors and
                assigns) has or hereafter can, shall or may have based on the Executive’s
                employment by the Company, any events that may have occurred during
                the
                course of his employment or the termination of that employment, or
                any
                other matters or claims of any kind or nature from the beginning
                of the
                world to the Effective Date (including without limitation, those
                arising
                out of or which may hereafter be claimed to arise out of the Employment
                Agreement or Executive’s status as a shareholder of the
                Company).  Without limiting the generality of the foregoing, the
                scope of this release includes (but is not limited to) a release
                of any
                and all claims for unpaid wages or other compensation, breach of
                contract,
                wrongful discharge, disability benefits, health and medical insurance,
                sick leave and employment discrimination.  Executive
                acknowledges and agrees that he is specifically releasing any rights
                or
                claims he may have under: the Age Discrimination in Employment Act
                (“ADEA”) (which prohibits discrimination in employment based on age);
                Older Workers Benefit Protection Act of 1990 (“OWBPA”) (which also
                prohibits discrimination in employment based on age); Title VII of
                the
                Civil Rights Act of 1964, which prohibits discrimination in employment
                based on race, color, national origin, religion or sex; the Equal
                Pay Act,
                which prohibits paying men and women unequal pay for equal work;

                of the Americans with Disabilities Act; the New York Human Rights
                Law; the

                local
                laws and regulations prohibiting discrimination in
                employment.  Executive acknowledges and agrees that this release
                covers not only claims that he knows about, but also claims that
                he might
                not know about.  Executive covenants and agrees that the release
                set forth in this Section 4 shall be binding upon his successors
                and
                assigns.  By signing this Agreement, Executive acknowledges and
                agrees that he is forever giving up his rights to make any of the
                claims
                or demands mentioned above.  For purposes of this Agreement,
                “Affiliate” means any entity that controls, is controlled by, or is under
                common control with the Company.

                other Party or, in the case of the Company, its respective Affiliates,
                or
                any of their employees, officers or directors, based on the actions
                of the
                other Party or the Company’s Affiliates or any of their employees,
                officers or directors, in connection with the Executive’s employment and
                the termination of his employment with the Company.  Each Party
                covenants and agrees that they will never file a lawsuit asserting
                any
                claims that such Party has released in Section 4
                above.

                with the

                make any public statement or take any action that is reasonably likely
                to
                be adverse, inimical or otherwise detrimental to the interests of
                such
                entities or persons.

                legal
                process, the Company agrees to use commercially reasonable efforts
                to
                cause its directors and executive officers not to (i) in any way
                publicly

              Non-Admission
                of Liability.  This Agreement and the release contained
                herein shall not be construed as evidence nor an admission of any
                wrongdoing or violation of any law, regulation, rule or
                agreement.

              Consequences
                if Violation of Certain Promises.If any Party must take legal action
                to enforce the terms of this Agreement, the prevailing Party will
                be
                entitled to receive reasonable attorney’s fees and costs from the
                non-prevailing Party.  The remedy provided under this Section 11
                shall not be construed to limit or exclude any other remedy available
                to
                the Parties under any other provision of this Agreement.  The
                preceding sentence shall not apply to any claims that Executive files
                under ADEA or OWBPA or any challenge that Executive makes to the
                validity
                of the ADEA or OWBPA waiver contained in this
                Agreement.  However, while Executive may challenge the validity
                of the ADEA or OWBPA waiver herein, in the event Executive unsuccessfully
                does so, Executive may be held liable for the attorneys' fees and
                costs of
                the Company to the same extent that successful defendants are allowed

              Equitable
                Remedies and Waiver. Each Party recognizes that irreparable injury
                will result to the other Party if a Party breaches any provision
                of this
                Agreement, and the Parties agree that if any Party should engage,
                or
                directly cause any other person or entity to engage, in any act in
                violation of any provision of this Agreement, then the non-breaching
                Party
                shall be entitled, in addition to any other remedies, damages and
                relief
                as may be available under applicable law, to seek an injunction
                prohibiting the breaching Party from engaging in any such act or
                specifically enforcing this

    Agreement,
      as the case may be.  It is understood and agreed that no failure or
      delay by the non-breaching Party in exercising any right, power or privilege
      under this Agreement shall operate as a waiver thereof, nor shall any single
      or
      partial exercise thereof preclude any other or further exercise thereof or
      the
      exercise of any right, power or privilege under this Agreement.

              Severability
                and Blue Penciling.  If any provision of this Agreement is
                held to be invalid, the remaining provisions shall remain in full
                force
                and effect.  However, if any court determines that any covenant
                in this Agreement or incorporated herein by reference from the Employment
                Agreement, including, without limitation, any restrictive covenant
                or any
                part thereof, is unenforceable because the duration, geographic scope
                or
                restricted activities thereof are overly broad, then such provision
                or
                part thereof shall be modified by reducing the overly broad duration,
                geographic scope or restricted activities to the maximum extent
                enforceable by law and, in such modified form, such provision shall
                be
                enforced.

              Choice
                of Law and Forum.  This Agreement shall be interpreted and
                enforced in accordance with the laws of the State of New York, without
                reference to its conflicts of laws principles.  The Parties
                hereby irrevocably consent to the exclusive jurisdiction of the state
                or
                federal courts sitting in New York, New York in connection with any
                controversy or claim arising out of or relating to this Agreement,
                Executive’s employment with the Company and/or the termination of such
                employment, and hereby waive any claim that such forum is inconvenient
                or
                otherwise improper.  Each Party hereby agrees that any such
                court shall have in personam jurisdiction over it and consents to
                service of process in any matter authorized by New York
                law.

              Mutual
                Waiver of Jury Trial.  Each Party hereto hereby waives the
                right to trial by jury in any action or proceeding based upon, arising
                out
                of, or in any way relating to this Agreement, Executive’s employment with
                the Company or the termination of such employment, whether sounding
                in
                contract, tort or otherwise.

              Successors
                and Assigns.  This Agreement shall be binding upon and shall
                inure to the benefit of the Parties and their respective heirs,
                successors, representatives and assigns, provided, however, that
                this
                Agreement is assignable to any legal successor of the Company but
                this
                Agreement may not be assigned by Executive.  Nothing herein
                limits the right of Executive’s estate to receive all consideration
                provided for in this Agreement should Executive become deceased during
                the
                Severance Period.

              Return
                of Company Property and Confidential Information.  The
                Executive acknowledges and agrees that he has delivered to the Company,
                without retaining any copies thereof, all evidence of the Confidential
                Information, including, without limitation, all notes, memoranda,

                any other
                form of technology.  The Executive hereby further
                acknowledges
