                           LOAN MODIFICATION AGREEMENT

     This Loan Modification Agreement ("Loan Modification") is entered into as
of December 12, 2005, by and between Partners for Growth, L.P., a Delaware
limited partnership with its principal place of business at 180 Pacific Avenue,
San Francisco, California 94111 ("PFG") and each of Qualmark Corporation, a
Colorado corporation and Qualmark ACG Corporation, a Colorado corporation, with
their principal place of business at 4580 Florence Street, Denver, Colorado
80238 ("Borrower").

     WHEREAS, Borrower has existing credit facilities with PFG and Silicon
Valley Bank ("SVB") and Borrower proposes to borrow additional funds from SVB of
up to $2,000,000 (the "Additional SVB Loan")

     WHEREAS, PFG and Borrower desire to modify certain of the Existing Loan
Documents (as defined below) to accommodate the Additional SVB Loan;

     NOW THEREFORE, the parties hereby agree as follows:

1. DESCRIPTION OF EXISTING INDEBTEDNESS: Among other indebtedness which may be
owing by Borrower to PFG, Borrower is indebted to PFG pursuant to, among other
documents, a Loan and Security Agreement, dated November 12, 2004, as it may be
amended from time to time (the "Loan Agreement"). The Loan Agreement provides
for a Term Loan in the original principal amount of One Million Dollars
($1,000,000) and an ability to request, subject to satisfaction of certain
conditions, an addition term loan of One Million Dollars ($1,000,000). Defined
terms used but not otherwise defined herein shall have the same meanings as set
forth in the Loan Agreement.

2. DESCRIPTION OF COLLATERAL. Repayment of the Obligations is secured by the
Collateral, as described in the Loan Agreement and in the Intellectual Property
Security Agreement. Hereinafter, the above-described security documents,
including the Cross-Corporate Continuing Guaranty of even date therewith,
together with all other documents securing repayment of the Indebtedness, shall
be referred to as the "Security Documents". Hereinafter, the Security Documents,
together with all other documents evidencing or securing the Indebtedness shall
be referred to as the "Existing Loan Documents".

<PAGE>

3. DESCRIPTION OF CHANGE IN TERMS.

     (a) Use of Proceeds of Additional SVB Loan. The parties acknowledge that
the conditions and requirements of Section 8(f) of the Loan Agreement have been
duly met and satisfied. The proceeds of the Additional SVB Loan are to be used
by Borrower exclusively to acquire the assets of LING Electronics from Satcon
Power Systems, Inc., a Delaware corporation, pursuant to that certain asset
purchase agreement dated on or about December 9, 2005 (the "LING Assets") and
for no other purpose. The LING Assets shall upon acquisition by Borrower become
a part of PFG's Collateral, subject to the rights of the Senior Lender.

     (b) The parties acknowledge the increased financial risk to PFG and the
value of its security interest in Borrower's Collateral resulting from the
Additional SVB Loan. On or before the date hereof, Borrower shall have wired to
PFG the sum of $350,000, which sum shall be held by PFG as additional security
for the obligations of Borrower under the Loan Agreement and this Loan
Modification (the "Deposit"). The Deposit shall not bear interest or affect the
accrual of interest on the Loan. PFG shall not be required to segregate the
Deposit from its general business accounts and the Deposit shall be solely
within PFG's dominion and control. Without any obligation to return the Deposit
in whole or in part, PFG will review Borrower's consolidated quarterly financial
performance and financial position on a calendar quarterly basis commencing
March 31, 2006 and at such time(s), re-evaluate, in its sole, good faith
discretion, its need to retain all or part of the Deposit as security for the
Obligations. At the Maturity Date, the then amount of the Deposit shall be
applied to the outstanding Obligations or, if PFG converts the Loan, shall be
promptly returned to Borrower.

     (c) The effectiveness of this Loan Modification is expressly conditional on
there being in effect a duly-executed amended Subordination Agreement between
PFG and SVB.

     (d) The "Senior Debt Limit" specified in Section 8(a)(2) of the Schedule to
the Loan Agreement entitled "ADDITIONAL PROVISIONS - SENIOR DEBT LIMIT" is
hereby amended to be $4,450,000.

     (e) From and after the date of this Loan Modification, interest shall be
paid quarterly in advance on the first day of each calendar quarter (and for the
first such quarter, including a pro rata amount from the date hereof until
December 31, 2005). From and after the date hereof, interest shall be paid not
in cash but in the Common Stock of Qualmark Corporation, provided however, if
Borrower declares and pays cash dividends on its Series B Preferred Stock and/or
its Series C Preferred Stock (but only for so long as it pays such dividends in
cash rather than stock), subject to not less than ninety (90) days notice to PFG
of the intention to make such

<PAGE>

payment in cash, Borrower shall commence to pay interest in cash as set forth in
the Loan Agreement rather than in Securities as set forth in this Section 3(e).
The number of Securities to be issued by Borrower to PFG each calendar quarter
shall be determined according to the following formula:

                     Y * A
          X = 0.25 * ------
                       B

Where

          X = the number of shares of Common Stock to be issued to PFG

          Y = the Applicable Interest Rate at the commencement of each calendar
              quarter

          A = the aggregate principal amount of all outstanding Loans

          B = the agreed Conversion Price, initially $1.66, as adjusted from
              time to time to reflect stock splits, combinations,
              reclassifications and similar events affecting the Common Stock

     For example only, the parties acknowledge that the Applicable Interest Rate
on the date hereof is seven percent (7%). For the calendar quarter commencing
January 1, 2006, Borrower would issue PFG 10,542 shares of its Common Stock (7%
times $1,000,000 principal of Loan outstanding, divided by the Conversion Price
($1.66), divided by 4 (0.25) to render a quarterly (rather than annual) number
of shares of Common Stock.

     In the event that PFG converts any or all of its Loan during a period in
which PFG has been issued Securities in advance of interest being earned in full
for such period, a pro rata adjustment of the number of Securities to be issued
in the next quarterly period shall be made, and if the Loan is converted in
whole, then PFG shall transfer to Borrower that number of Securities as
represents such overpaid interest, all upon the formula set forth above.

     The term "Applicable Interest Rate" means the Interest Rate as of the
commencement of each calendar quarter, as adjusted (from time to time, if at
all) pursuant to the Interest Rate Reset provision of this Schedule.

4.   REPRESENTATIONS AND WARRANTIES OF THE PARTIES.

     (iii) Capitalization. The authorized capital stock of Borrower consists as
of the date hereof of the following: (1) 4,418,000 shares of its Common Stock,

provision of the Restated Certificate of Incorporation or Bylaws, as amended, or
any mortgage, indenture, lease or other agreement or instrument, permit,
concession, franchise, license, judgment, order, decree, statute, law,
ordinance, rule or regulation applicable to Borrower, its properties or assets,
the effect of which would have a material adverse effect on Borrower or
materially impair or restrict its power to perform its obligations as
contemplated hereby or thereby.

     (v) Governmental and other Consents. No consent, approval, order or
authorization of, or registration, qualification, designation, declaration or
filing with, any governmental authority or other person or entity is required on
the part of Borrower in connection with the execution, delivery and performance

state securities laws.

     (b) Representations and Warranties of PFG. PFG hereby represents and
warrants to Borrower as of the Closing Date as follows:

     (i) Investment Experience. PFG is an "accredited investor" within the
meaning of Rule 501 under the Securities Act, and was not organized for the
specific purpose of acquiring the Securities. PFG is aware of Borrower's
business affairs and financial condition and has acquired sufficient information
about Borrower to reach an informed and knowledgeable decision to acquire the
Securities. PFG has such business and financial experience as is required to
give it the capacity to protect its own interests in connection with the
purchase of the Securities.

     (ii) Investment Intent. PFG is purchasing the Securities for investment for
its own account only and not with a view to, or for resale in connection with,
any "distribution" thereof within the meaning of the Securities Act.

     (iii) Authorization. PFG has all requisite power and has taken all
requisite action to execute and deliver each of this Loan Modification and to
carry out and perform all of its obligations hereunder. This Loan Modification
has been duly authorized, executed and delivered on behalf of PFG and
constitutes the valid and binding agreement of PFG, enforceable in accordance
with its terms, except as limited by applicable bankruptcy, insolvency,
reorganization or similar laws relating to or affecting the enforcement of
creditors' rights generally and as limited by equitable principles generally.
The consummation of the transactions contemplated herein and the fulfillment of
the terms herein will not result in a breach of any of the terms or provisions
of PFG's partnership agreement or other relevant organizational documents.

5. CONSISTENT CHANGES. The Existing Loan Documents are hereby amended wherever
necessary to reflect the changes described above.

6. PAYMENT OF LOAN FEE AND EXPENSES. Borrower shall pay all of PFG's costs and
expenses, including attorneys' fees, incurred in connection with this Loan
Modification and the Additional SVB Loan..

7. NO DEFENSES. Borrower agrees that, as of the date hereof, it has no defenses
against the obligations to pay any amounts under the Indebtedness.

8. CONTINUING VALIDITY. Borrower understands and agrees that in modifying the
existing Indebtedness, PFG is relying upon Borrower's representations,
warranties, and agreements, as set forth in the Existing Loan Documents. Except
as expressly modified pursuant to this Loan Modification, the terms of the
Existing Loan Documents remain unchanged and in full force and effect. PFG's
agreement to modifications to the existing Indebtedness and the consent to the
Additional SVB Loan pursuant to this Loan Modification in no way shall obligate
PFG to make any future consents, waivers or modifications to the Indebtedness.
Nothing in this Loan Modification shall constitute a satisfaction of the
Indebtedness or a waiver of any default under the Existing Loan Documents. It is
the intention of PFG and Borrower to retain as liable parties all

<PAGE>

makers and endorsers of Existing Loan Documents, unless the party is expressly
released by PFG in writing. Unless expressly released herein, no maker,
endorser, or guarantor will be released by virtue of this Loan Modification. The
terms of this Section 8 apply not only to this Loan Modification, but also to
all subsequent loan modification agreements.

(a) evidence of the consent of the Board of Directors of Borrower and, to the
extent required, the stockholders of Borrower, to this Loan Modification and the
issue of Securities to PFG; (b) PFG's receipt of a fully executed counterpart
hereof, (c) PFG's receipt of a duly-executed amendment to the Subordination
Agreement between PFG and the Senior Lender; (d) PFG's receipt of an update to
the Representations of Borrower, including without limitation, an update to
reflect the acquisition of the LING Assets, and Borrower's cooperation in making
such additional filings as may be deemed necessary by PFG to perfects its
security interest the LING Assets, once acquired by Borrower; (e) use of the
proceeds of the Additional SVB Loan as set forth in Section 3(a) of this Loan
Modification; and (f) the truth and accuracy of the Representations and
Warranties of Borrower set forth in Section 4 of this Loan Modification.

10. MISCELLANEOUS. The quotation marks around modified clauses set forth herein
and any differing font styles in which such clauses are presented herein are for
ease of reading only and shall be ignored for purposes of construing and

Seller shall execute and deliver such other instruments of sale, transfer,
conveyance and assignment and take such actions as the Buyer may reasonably

confirm the Buyer's rights to, title in and ownership of, the Acquired Assets
and to place the Buyer in actual possession and operating control thereof.

which the nature of the Seller's businesses or the ownership or leasing of its

Material Adverse Effect. The Seller has all requisite corporate power and
authority to carry on the businesses in which it is engaged and to own and use
the properties owned and used by it. The Seller has furnished to the Buyer

authorized by all necessary corporate action on the part of the Seller. This
Agreement has been duly and validly executed and delivered by the Seller and
constitutes, and each of the Ancillary Agreements, upon its execution and
delivery by the Seller, will constitute, a valid and binding obligation of the
Seller, enforceable against the Seller in accordance with its terms.

Agreements, nor the consummation by the Seller of the transactions contemplated
hereby or thereby, will (a) conflict with or violate any provision of the
Certificate of Incorporation or by-laws of the Seller, (b) require on the part

which the Seller is bound or to which any of its respective assets is subject,
except for (i) any conflict, breach, default, acceleration, termination,
modification or cancellation which, individually or in the aggregate, would not
have a Seller Material Adverse Effect and would not adversely affect the
consummation of the transactions contemplated hereby or (ii) any notice, consent
or waiver the absence of which, individually or in the aggregate, would not have
a Seller Material Adverse Effect and would not adversely affect the consummation
of the transactions contemplated hereby, (d) result in the imposition of or
acceleration of any Security Interest upon any assets of the Seller or (e)
violate any order, writ, injunction, decree, statute, rule or regulation

and its respective affiliates and persons serving as officers, directors,
partners or employees thereof harmless from and against any damages,
liabilities, losses, taxes, fines, penalties, costs, and expenses (including,

(whether or not arising out of third-party claims, and including all amounts
paid in investigation, defense or settlement of the foregoing) ("claims") which
may be sustained or suffered by any of them arising out of or based upon any of
the following matters:

          (a) breach by Seller of any of its representations, warranties,
covenants or agreements under this Agreement or in any Ancillary Agreement,
certificate, schedule or exhibit delivered pursuant hereto;

          (b) any failure by Seller to perform and discharge any covenant or
agreement of the Seller contained in the Agreement or any Ancillary Agreement,
or other agreement or instrument furnished by the Seller to the Buyer pursuant
to this Agreement;

          (c) any Retained Liabilities; and

          (d) pre-closing activities of the Seller relating to the Acquired
Business except to the extent that the same constitute Assumed Liabilities.

     7.2 Indemnification by Buyer. Buyer agrees to indemnify and hold Seller and
its respective affiliates and persons serving as officers, directors or
employees thereof harmless from and against any damages, liabilities, losses and
expenses (including, without limitation, reasonable fees of counsel) of any kind
or nature whatsoever (whether or not arising out of third-party claims, and
including all amounts paid in investigation, defense or settlement of the
foregoing) ("claims") which may be sustained or suffered by any of them arising
out of or based upon any of the following matters:

          (a) breach by Buyer of any of its representations, warranties or
covenants under this Agreement or in any Ancillary Agreement, certificate,
schedule or exhibit delivered pursuant hereto; and

<PAGE>

          (b) any failure by Buyer to perform and discharge any covenant or
agreement of the Buyer contained in the Agreement or any Ancillary Agreement, or
other agreement or instrument furnished by the Buyer to the Seller pursuant to
this Agreement;

          (c) any Assumed Liabilities; and

          (d) post-closing activities of the Buyer relating to the operation of
the Acquired Business.

     7.3 Notice; Defense of Claims An Indemnified Party may make claims for
indemnification hereunder by giving written notice thereof to the Indemnifying
Party within the period in which indemnification claims can be made hereunder.
If indemnification is sought for a claim or liability asserted by a third party,
the Indemnified Party shall also give written notice thereof to the Indemnifying
Party promptly after it receives notice of the claim or liability being
asserted, but the failure to do so shall not relieve the Indemnifying Party from
any liability except to the extent that it is prejudiced by the failure or delay
in giving such notice. Such notice shall summarize the bases for the claim for
indemnification and any claim or liability being asserted by a third party.
Within 20 days after receiving such notice, the Indemnifying Party shall give
written notice to the Indemnified Party stating whether it disputes the claim
for indemnification and whether it will defend against any third-party claim or
liability at its own cost and expense. If the Indemnifying Party fails to give
notice that it disputes an indemnification claim within 20 days after receipt of
notice thereof, it shall be deemed to have accepted and agreed to the claim,
which shall become immediately due and payable. The Indemnifying Party shall be
entitled to direct the defense against a third-party claim or liability with
counsel selected by it (subject to the consent of the Indemnified Party, which
consent shall not be unreasonably withheld) as long as the Indemnifying Party is
conducting a good faith and diligent defense. The Indemnified Party shall at all
times have the right to fully participate in the defense of a third-party claim
or liability at its own expense directly or through counsel; provided, however,
that if the named parties to the action or proceeding include both the
Indemnifying Party and the Indemnified Party, and the Indemnified Party is
advised that representation of both parties by the same counsel would be
inappropriate under applicable standards of professional conduct, the
Indemnified Party may engage separate counsel at the expense of the Indemnifying
Party. If no such notice of intent to dispute and defend a third-party claim or
liability is given by the Indemnifying Party, or if such good faith and diligent
defense is not being or ceases to be conducted by the Indemnifying Party, the
Indemnified Party shall have the right, at the expense of the Indemnifying
Party, to undertake the defense of such claim or liability (with counsel
selected by the Indemnified Party), and to compromise or settle it, exercising
reasonable business judgment. If the third-party claim or liability is one that
by its nature cannot be defended solely by the Indemnifying Party, then the
Indemnified Party shall make available such information and assistance as the
Indemnifying Party may reasonably request and shall cooperate with the
Indemnifying Party in such defense, at the expense of the Indemnifying Party.
Except for claims of fraud, intentional misrepresentation, and willful
misconduct of Seller, and claims for breach of Seller's representations
regarding broker fees, Buyer shall not have the right to bring any claim for
indemnification with respect to the breach of a representation or warranty until
the aggregate amount of Buyer claims for indemnification exceed $30,000. Once
said $30,000 threshold is met, however, such indemnification shall commence at
$30,000.

     7.4 Treatment of Indemnity Payments. Any payments made to an Indemnified
Party pursuant to this Article VII shall be treated as an adjustment to the
Purchase Price for tax purposes.

     7.5 Limitations. Notwithstanding anything to the contrary contained herein
or in any Ancillary Agreement, each Party's indemnification obligations shall
terminate 18 months following the execution of this Agreement (the
"Indemnification Period"), except for those claims for which notice has been
properly given pursuant to Section 7.3 herein, within such Indemnification
Period, and except for those claims that are based on fraud, intentional
misrepresentation, willful misconduct, product liability, infringement claims by
third parties, or breach of the Parties' obligations of confidentiality or
non-competition. Each Party's aggregate liability for indemnification claims,
except to the extent such claims are based on fraud, intentional
misrepresentation, willful misconduct, product liability, infringement claims by
third parties, or the breach of the Parties' obligations of confidentiality or
noncompetition, shall not exceed the Purchase Price.

within 20 days following delivery by the Seller to the Buyer of written notice
of such breach;

     8.2 Effect of Termination. If either Party terminates this Agreement
pursuant to Section 8.1, all obligations of the Parties hereunder shall
terminate without any liability of either Party to the other Party (except for
any liability of a Party for willful breaches of this Agreement, in any event,
not to exceed the Purchase Price).

     Either Party may give any notice, request, demand, claim, or other
communication hereunder using any other means (including personal delivery,
expedited courier, messenger service, telecopy, telex, ordinary mail, or
electronic mail), but no such notice, request, demand, claim, or other
communication shall be deemed to have been duly given unless and until it
actually is received by the party for whom it is intended. Either Party may
change the address to which notices, requests, demands, claims, and other
communications hereunder are to be delivered by giving the other Party notice in
the manner herein set forth.

     10.8 Governing Law. This Agreement shall be governed by and construed in
accordance with the internal laws of the Commonwealth of Massachusetts, without
giving effect to any choice or conflict of law provision or rule (whether of the
Commonwealth of Massachusetts or any other jurisdiction) that would cause the
application of laws of any jurisdictions other than those of the Commonwealth of
Massachusetts.

     10.9 Amendments and Waivers. The Parties may mutually amend any provision
of this Agreement at any time prior to the Closing. No amendment of any
provision of this Agreement shall be valid unless the same shall be in writing
and signed by each of the Parties. No waiver by either Party of any right or
remedy hereunder shall be valid unless the same shall be in writing and signed
by the Party giving such waiver. No waiver by either Party with respect to any
default, misrepresentation, or breach of warranty or covenant hereunder shall be
deemed to extend to any prior or subsequent default, misrepresentation, or
breach of warranty or covenant hereunder or affect in any way any rights arising
by virtue of any prior or subsequent such occurrence.

     10.10 Severability. Any term or provision of this Agreement that is invalid
or unenforceable in any situation in any jurisdiction shall not affect the
validity or enforceability of the remaining terms and provisions hereof or the
validity or enforceability of the offending term or provision in any other
situation or in any other jurisdiction. If the final judgment of a court of
competent jurisdiction declares that any term or provision hereof is invalid or
unenforceable, the Parties agree that the court making the determination of
invalidity or unenforceability shall have the power to limit the term or
provision, to delete specific words or phrases, or to replace any invalid or
unenforceable term or provision with a term or provision that is valid and
enforceable and that comes closest to expressing the intention of the invalid or
unenforceable term or provision, and this Agreement shall be enforceable as so
modified.

     10.11 Expenses. Except as set forth in Article VII, each Party shall bear
its own costs and expenses (including legal fees and expenses) incurred in
connection with this Agreement and the transactions contemplated hereby.

     10.12 Specific Performance. Each Party acknowledges and agrees that the
other Party would be damaged irreparably in the event any of the provisions of
this Agreement (including Sections 6.1 and 6.2) are not performed in accordance
with their specific terms or otherwise are breached. Accordingly, each Party
agrees that the other Party shall be entitled to an injunction or other
equitable relief to prevent breaches of the provisions of this Agreement and to
enforce specifically this Agreement and the terms and provisions hereof in any
action instituted in any court of the United States or any state thereof having
jurisdiction over the Parties and the matter, in addition to any other remedy to
which it may be entitled, at law or in equity.
