                           LOAN AND SECURITY AGREEMENT

     THIS LOAN AND SECURITY AGREEMENT (this "AGREEMENT") dated _December 8,
2005, 2005 but effective only as of the Effective Date by and among SILICON
VALLEY BANK, a California corporation, with its principal place of business at
3003 Tasman Drive, Santa Clara, California 95054 and with a loan production
office at 4410 Arapahoe Avenue, Suite 200, Boulder, CO 80303 ("BANK"), QUALMARK
CORPORATION, a Colorado corporation, with its chief executive office at 4580
Florence Street, Denver CO 80238 ("QUALMARK ") and each of the other Persons
executing this Agreement as a Borrower (together with QUALMARK, each a
"BORROWER" and collectively and jointly and severally, the "BORROWERS"),
provides the terms on which Bank shall lend to Borrowers and Borrowers shall
repay Bank.

QUALMARK and Bank entered into a Loan and Security Agreement which was effective
as of November 9, 2004 (as it has been and may from time to time be further
amended, modified, supplemented or restated, the "Prior Loan Agreement") which
will continue to govern the Term Loan Advance (as defined therein) made
thereunder but not the Committed Revolving Line (as defined therein) provided
for therein (herein called the "Revolving Line"), but this Agreement shall
govern the terms of the Revolving Line and upon execution hereof the terms of
the Prior Loan Agreement which apply to the Committed Revolving Line thereunder
are hereby terminated.

The parties agree as follows:

     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. QUALMARK will act as the agent for each Borrower for
purposes of this Agreement.

     LOAN AND TERMS OF PAYMENT

     Promise to Pay. BORROWERS HEREBY JOINTLY AND SEVERALLY UNCONDITIONALLY
PROMISE 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.

     REVOLVING ADVANCES.

          Availability. Subject to the terms and conditions of this Agreement,
Bank shall make Advances to each Borrower not exceeding the Availability Amount.
Amounts borrowed under the Revolving Line may be repaid and, prior to the
Revolving Line Maturity Date, reborrowed, subject to the applicable terms and
conditions precedent herein.

          Termination; Repayment. The Revolving Line terminates on the Revolving
Line Maturity Date, when the principal amount of all Advances, the unpaid
interest thereon, and all other Obligations relating to the Revolving Line shall
be immediately due and payable.

     LETTERS OF CREDIT SUBLIMIT.

     As part of the Revolving Line, Bank shall issue or have issued Letters of
Credit for each Borrower's account. The face amount of all Borrowers'
outstanding Letters of Credit (including drawn but unreimbursed Letters of
Credit and any Letter of Credit Reserve) may not exceed $200,000.00. Such
aggregate amounts utilized hereunder shall at all times reduce the amount
otherwise available for Advances under the Revolving Line. If, on the Revolving
Maturity Date, there are any outstanding Letters of Credit, then on such date
each Borrower shall provide to Bank cash

<PAGE>

collateral in an amount equal to 105% of the face amount of all such Letters of
Credit issued for such Borrower plus all interest, fees, and costs due or to
become due in connection therewith (as estimated by Bank in its good faith
business judgment), to secure all of the Obligations relating to said Letters of
Credit. All Letters of Credit shall be in form and substance acceptable to Bank
in its sole discretion and shall be subject to the terms and conditions of
Bank's standard Application and Letter of Credit Agreement (the "LETTER OF
CREDIT APPLICATION"). Each Borrower agrees to execute any further documentation
in connection with the Letters of Credit issued for such Borrower as Bank may
reasonably request.

          The obligation of each Borrower to immediately reimburse Bank for
drawings made under Letters of Credit issued for such Borrower shall be
absolute, unconditional, and irrevocable, joint and several with all other
Borrowers and shall be performed strictly in accordance with the terms of this
Agreement, such Letters of Credit issued for such Borrower, and all related
Letter of Credit Applications.

          Borrower may request that Bank issue a Letter of Credit payable in a
Foreign Currency. If a demand for payment is made under any such Letter of
Credit, Bank shall treat such demand as an Advance to Borrower of the equivalent
of the amount thereof (plus fees and charges in connection therewith such as
wire, cable, SWIFT or similar charges) in Dollars at the then-prevailing rate of
exchange in San Francisco, California, for sales of the Foreign Currency for
transfer to the country issuing such Foreign Currency.

          To guard against fluctuations in currency exchange rates, upon the
issuance of any Letter of Credit payable in a Foreign Currency, Bank shall
create a reserve (the "LETTER OF CREDIT RESERVE") under the Revolving Line in an
amount equal to ten percent (10%) of the face amount of such Letter of Credit.
The amount of the Letter of Credit Reserve may be adjusted by Bank from time to
time to account for fluctuations in the exchange rate. The availability of funds
under the Revolving Line shall be reduced by the amount of such Letter of Credit
Reserve for as long as such Letter of Credit remains outstanding.

     FOREIGN EXCHANGE SUBLIMIT. As part of the Revolving Line, each Borrower may
enter into foreign exchange contracts with Bank under which such Borrower
commits to purchase from or sell to Bank a specific amount of Foreign Currency
(each, a "FX FORWARD Contract") on a specified date (the "SETTLEMENT DATE"). FX
Forward Contracts shall have a Settlement Date of at least one (1) FX Business
Day after the contract date and shall be subject to a reserve of ten percent
(10%) of each outstanding FX Forward Contract in a maximum aggregate amount for
all Borrowers equal to $200,000.00 (the "FX RESERVE"). The aggregate amount of
FX Forward Contracts at any one time may not exceed ten (10) times the amount of
the FX Reserve. The obligations of each Borrower relating to this section may
not exceed the Availability Amount.

     CASH MANAGEMENT SERVICES SUBLIMIT. Borrowers may use up to $200,000.00 (the
"CASH MANAGEMENT SERVICES SUBLIMIT") of the Revolving Line for Bank's cash
management services which may include merchant services, direct deposit of
payroll, business credit card, and check cashing services identified in Bank's
various cash management services agreements (collectively, the "CASH MANAGEMENT
SERVICES"). Any amounts Bank pays on behalf of any Borrower or any amounts that
are not paid by any Borrower for any Cash Management Services will be treated as
Advances to the relevant Borrower under the Revolving Line and will accrue
interest at the interest rate applicable to Advances.

     2.1.5 TERM LOAN.

     (a) AVAILABILITY. Bank shall make a term loan available to QualMark Ling
Corporation in an amount up to $2,000,000.00 (the "Term Loan") on or promptly
after the Effective Date upon the closing of the acquisition of assets of Ling
Electronics from SATCON Power Systems, Inc. by QualMark Ling Corporation,
subject to the satisfaction of the terms and conditions of this Agreement. When
repaid the Term Loan may not be reborrowed.

     (B) REPAYMENT. Borrowers shall repay the Term Loan in thirty six (36) equal
monthly installments of principal, each in the amount that will fully and evenly
amortize the principal amount of the such Term Loan actually advanced, plus
interest (each, a "Loan Payment"). Loan Payments on the Term Loan shall commence
on January 1, 2006 and thereafter shall be payable on the first day of each
month to and including December 1, 2008 (the "Term Loan Maturity Date").
Interest shall be payable on the Term Loan, payable monthly, beginning on the
first day of the month following the month in which the Funding Date occurs.
Borrower's final Loan Payment on the Term Loan, due on the Term Loan Maturity
Date, shall include all outstanding principal and accrued and unpaid interest
under the Term Loan.

<PAGE>

     (C) PREPAYMENT. At Borrowers' option, so long as an Event of Default has
not occurred and is not continuing, Borrowers shall have the option to prepay
all, but not less than all, of the principal amount of the Term Loan advanced by
Bank under this Agreement, provided QUALMARK, (a) provides written notice to
Bank of the election to prepay such Term Loan at least thirty (30) days prior to
such prepayment, and (b) pays, on the date of the prepayment (i) all accrued and
unpaid interest with respect to the Term Loan through the date the prepayment is
made; (ii) all unpaid principal with respect to the Term Loan; (iii) a premium
equal to the Make-Whole Premium, provided that a one-time prepayment of
$500,000.00 may be made without payment of a Make-Whole Premium; and (iv) all
other sums, including Bank Expenses, if any, that have become due and payable
hereunder with respect to the Term Loan as of the date of such prepayment.

     Overadvances. IF, AT ANY TIME, THE CREDIT EXTENSIONS TO ANY BORROWER UNDER
SECTIONS 2.1.1, 2.1.2, 2.1.3 AND 2.1.4 EXCEED THE AVAILABILITY AMOUNT FOR SUCH
BORROWER, SUCH BORROWER SHALL IMMEDIATELY PAY TO BANK IN CASH SUCH EXCESS.

     Payment of Interest on the Credit Extensions.

          Interest Rate.

               (i) Advances. Subject to Section 2.3(b), the principal amount
outstanding under the Revolving Line shall accrue interest at a floating per
annum rate equal to one percentage point (1.00%) above the Prime Rate, which
interest shall be payable monthly in accordance with Section 2.3(f) below, but
such rate shall not be less than 5.5% per annum.

               (ii) Term Loan. Subject to Section 2.3(b), the principal amount
outstanding under the Term Loan shall accrue interest at a per annum rate equal
to the Term Loan Basic Rate, which interest shall be payable monthly.

          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 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 2.3(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.

          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.

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

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

          Payments. Unless otherwise provided, interest is payable monthly on
the first calendar day of each month. Payments of principal and/or interest
received after 12:00 p.m. Pacific 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.

     Fees. BORROWERS SHALL PAY TO BANK:

          Loan Commitment Fee. A fully earned, non-refundable loan commitment
fee of $15,000.00, on the Effective Date;

<PAGE>

SUCH BORROWER SHALL PROMPTLY NOTIFY BANK IN A WRITING SIGNED BY SUCH BORROWER OF
THE GENERAL DETAILS THEREOF AND GRANT TO BANK IN SUCH WRITING A SECURITY

     continue until the Obligations (other than inchoate indemnity obligations)
     are repaid in full in cash. Upon payment in full in cash of the Obligations

ON BEHALD OF ALL BORROWERS, HAS DELIVERED TO BANK A COMPLETED CERTIFICATE
SUBSTANTIALLY IN THE FORM ATTACHED HERETO AS EXHIBIT E SIGNED BY QUALMARK,

OCCURRENCE AND PROVIDE BANK WITH SUCH BORROWER'S ORGANIZATIONAL IDENTIFICATION
NUMBER.

     The execution, delivery and performance of the Loan Documents have been
duly authorized, and do not conflict with any Borrower's organizational
documents, nor constitute an event of default under any material agreement by
which any Borrower is bound. Each Borrower is not in default under any agreement

CUSTOMERS IN THE ORDINARY COURSE OF BUSINESS. EACH PATENT IS VALID AND
ENFORCEABLE, AND NO PART OF THE INTELLECTUAL PROPERTY HAS BEEN JUDGED INVALID OR

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.

EXPENSES, LIABILITIES, OBLIGATIONS AND ATTORNEYS' FEES INCURRED BY BANK IN THE
EXERCISE OF ITS RIGHTS UNDER THIS AGREEMENT; SECOND, TO THE INTEREST DUE UPON
ANY OF THE OBLIGATIONS; AND THIRD, TO THE PRINCIPAL OF THE OBLIGATIONS AND ANY

     10.2 BORROWER JOINT AND SEVERAL LIABILITY. Notwithstanding anything to the
contrary contained in this Agreement, all of Borrowers' representations and
warranties, indebtedness, liabilities, and other Obligations of any kind
described in this Agreement and any other Loan Document shall be joint and
several in nature and affect their jointly and/or severally owned property. Any
Borrower may, acting singly through QUALMARK , request Advances. Each Borrower
hereby appoints QUALMARK as agent for such Borrower for all purposes hereunder,
including with respect to requesting Advances. Each Borrower shall be jointly
and severally obligated to repay all Advances made, regardless of which Borrower
actually receives said Advance, as if each Borrower directly received all
Advances.

     10.3 SUBROGATION AND SIMILAR RIGHTS. Notwithstanding any other provision of
this Agreement or any other Loan Document, until payment to Bank in full and
performance of all Obligations, each Borrower irrevocably waives all rights that
it may have at law or in equity (including, without limitation, any law
subrogating such Borrower to the rights of Bank under the Loan Documents) to
seek contribution, indemnification, or any other form of reimbursement from any
other Borrower, or any other Person now or hereafter primarily or secondarily
liable for

<PAGE>

any of the Obligations, for any payment made by such Borrower with respect to
the Obligations in connection with the Loan Documents or otherwise and all
rights that it might have to benefit from, or to participate in, any security
for the Obligations as a result of any payment made by such Borrower with
respect to the Obligations in connection with the Loan Documents or otherwise,
in each case until the Obligations are indefeasibly paid in full. Any agreement
providing for indemnification, reimbursement or any other arrangement prohibited
under this Section 10.3 shall be null and void, in each case until the
Obligations are indefeasibly paid in full. If any payment is made to any
Borrower in contravention of this Section 10.3, such Borrower shall hold such
payment in trust for Bank and such payment shall be promptly delivered to Bank
for application to the Obligations, whether matured or unmatured.

     10.4 WAIVERS OF NOTICE. Each Borrower waives notice of acceptance hereof by
the other Borrowers and by Bank. Each Borrower also waives notice, with respect
to the Obligations of the other Borrowers, of the following: notice of the
existence, creation or acquisition of any of the Obligations; notice of an Event
of Default; notice of the amount of the Obligations outstanding at any time;
notice of intent to accelerate; notice of acceleration; notice of any adverse
change in the financial condition of any other Borrower or of any other fact
that might increase such Borrower's risk; presentment for payment; demand;
protest and notice thereof as to any instrument; default; and all other notices
and demands as to any other Borrower to which such Borrower would otherwise be
entitled. Each Borrower waives any defense arising from any defense of any other
Borrower, or by reason of the cessation from any cause whatsoever of the
liability of any other Borrower. Bank's failure at any time to require strict
performance by any Borrower of any provision of the Loan Documents shall not
waive, alter or diminish any right of Bank thereafter to demand strict
compliance and performance therewith. Nothing contained herein shall prevent
Bank from foreclosing on the Lien of any deed of trust, mortgage or other
security instrument, or exercising any rights available thereunder, and the
exercise of any such rights shall not constitute a legal or equitable discharge
of any Borrower. Each Borrower also waives any defense arising from any act or
omission of Bank that changes the scope of such Borrower's risks as a joint
obligor hereunder. Each Borrower hereby waives any right to assert against Bank
any defense (legal or equitable), setoff, counterclaim, or claims that such
Borrower individually may now or hereafter have against another Borrower or any
other Person liable to such Borrower with respect to the Obligations in any
manner or whatsoever until the Obligations are indefeasibly paid in full to
Bank.

     10.5 SUBROGATION DEFENSES. Each Borrower waives the benefits, if any, of
any statutory or common law rule that may permit a borrower to assert any
defenses of a surety or guarantor, or that may give a borrower the right to
require a senior creditor to marshal assets, and such Borrower agrees that it
shall not assert any such defenses or rights.

     10.6 RIGHT TO SETTLE, RELEASE.

     (a) The liability of each Borrower hereunder shall not be diminished by (i)
any agreement, understanding or representation that any of the Obligations is or
was to be guaranteed by another Person or secured by other property, or (ii) any
release or unenforceability of any of the Obligations, whether partial or total,
or of rights, if any, which such Borrower may now or hereafter have against any
other Person, including another Borrower, or property with respect to any of the
Obligations.

     (b) Without notice to any Borrower and without affecting the liability of
any Borrower as a joint obligor hereunder, Bank may (i) compromise, settle,
renew, extend the time for payment, change the manner or terms of payment,
discharge the performance of, decline to enforce, or release all or any of the
Obligations with respect to any Borrower, (ii) grant other indulgences to any
Borrower in respect of the Obligations, (iii) modify in any manner any
documents, relating to the Obligations with respect to any Borrower, (iv)
release, surrender or exchange any deposits or other property securing the
Obligations, whether pledged by any Borrower or any other Person, or (v)
compromise, settle renew, or extend the time for payment, discharge the
performance of, decline to enforce, or release all or any obligations of any
guarantor, endorser or other Person who is now or may hereafter be liable with
respect to any of the Obligations.

     CHOICE OF LAW, VENUE AND JURY TRIAL WAIVER

     Colorado law governs the Loan Documents without regard to principles of
conflicts of law. Borrowers and Bank each submit to the exclusive jurisdiction
of the State and Federal courts in City and County of Denver, State of Colorado;
provided, however, that nothing in this Agreement shall be deemed to operate to
preclude Bank from

<PAGE>

bringing suit or taking other legal action in any other jurisdiction to realize
on the Collateral or any other security for the Obligations, or to enforce a
judgment or other court order in favor of Bank. Each Borrower expressly submits
and consents in advance to such jurisdiction in any action or suit commenced in
any such court, and each Borrower hereby waives any objection that it may have
based upon lack of personal jurisdiction, improper venue, or forum non
conveniens and hereby consents to the granting of such legal or equitable relief
as is deemed appropriate by such court. Each Borrower hereby waives personal
service of the summons, complaints, and other process issued in such action or
suit and agrees that service of such summons, complaints, and other process may
be made by registered or certified mail addressed to such Borrower at the
address set forth in Section 10 of this Agreement and that service so made shall
be deemed completed upon the earlier to occur of such Borrower's actual receipt
thereof or three (3) days after deposit in the U.S. mails, proper postage
prepaid.
