     This Asset Purchase Agreement is entered into as of December , 2005 by and
between Qualmark Ling Corporation, a Colorado corporation (the "Buyer"), and
SatCon Power Systems, Inc., a Delaware corporation (the "Seller").

     This Agreement contemplates a transaction in which the Buyer will purchase
certain of the assets and assume certain of the liabilities of the Seller
related to its Ling Shaker and Amplifier business.

     Capitalized terms used in this Agreement shall have the meanings ascribed
to them in Article IX.

     In consideration of the representations, warranties and covenants herein
contained, the Parties agree as follows.

                                    ARTICLE I

                               THE ASSET PURCHASE

     1.1 Purchase and Sale of Assets.

          (a) Upon and subject to the terms and conditions of this Agreement,
the Buyer shall purchase from the Seller, and the Seller shall sell, transfer,
convey, assign and deliver to the Buyer, at the Closing, for the consideration
specified below in this Article I, all right, title and interest in, to and
under the Acquired Assets.

          (b) Notwithstanding the provisions of Section 1.1(a), the Acquired
Assets shall not include the Excluded Assets.

     1.2 Assumption of Liabilities.

          (a) Upon and subject to the terms and conditions of this Agreement,
the Buyer shall assume and become responsible for, from and after the Closing,
the Assumed Liabilities.

          (b) Notwithstanding the terms of Section 1.2(a) or any other provision
of this Agreement to the contrary, the Buyer shall not assume or become
responsible for, and the Seller shall remain liable for, the Retained

modification or cancellation which, individually or in the aggregate, would not

     6.1 Proprietary Information. From and after the Closing, the Seller shall
not disclose or make use of (except to pursue its rights under this Agreement
and the Ancillary Agreements), any knowledge, information or documents of a
confidential nature or not generally known to the public with respect to
Acquired Assets except (i) such information relating to the PM10 Designs in the
power systems market, and (ii) to the extent that such knowledge, information or
documents shall have become public knowledge other than through improper
disclosure by the Seller or an affiliate. The Seller shall, if reasonably
requested by the Buyer, enforce, for the benefit of the Buyer, all
confidentiality, invention assignments and similar agreements between the Seller
and any other party relating to the Acquired Assets. In the event that, after
the Closing Date, either Party shall discover that it is holding in its
possession Intellectual Property that is the property of the other Party in
accordance with the terms of this Agreement, such Party will immediately notify
the other Party and undertake best efforts to deliver such Intellectual Property
to the other Party within a commercially reasonable time frame.

     6.2 Non-Competition.

          (a) For a period of 3 years after the Closing Date, the Seller shall
not, either directly or indirectly as a stockholder, investor, partner,
consultant or otherwise, (i) design, develop, manufacture, market, sell or
license any product or provide any service anywhere in the world which is

other party which are not Assigned Contracts.

          (b) The Seller agrees that the duration and geographic scope of the
non-competition provision set forth in this Section 6.2 are reasonable. In the
event that any court determines that the duration or the geographic scope, or
both, are unreasonable and that such provision is to that extent unenforceable,
the Parties agree that the provision shall remain in full force and effect for
the greatest time period and in the greatest area that would not render it
unenforceable. The Parties intend that this non-competition provision shall be
deemed to be a series of separate covenants, one for each and every county of
each and every state of the United States of America and each and every
political subdivision of each and every country outside the United States of
America where this provision is intended to be effective.

promptly when due any and all sales/use tax incurred in connection with the

litigation or proceeding already instituted or which may be instituted hereafter
against or by such other Party relating to or arising out of the conduct of the
business of the Seller or the Buyer prior to or after the Closing Date (other
than litigation among the Parties and/or their affiliates arising out the
transactions contemplated by this Agreement). The Party requesting such
cooperation shall pay the reasonable out-of-pocket expenses incurred in
providing such cooperation (including legal fees and disbursements) by the Party
providing such cooperation and by its officers, directors, employees and agents,
but shall not be responsible for reimbursing such Party or its officers,
directors, employees and agents, for their time spent in such cooperation.

     6.5 Solicitation and Hiring. It is understood and agreed between the
parties that the transaction set forth herein does not include any employees of
Seller, and that Seller shall retain all liabilities and obligations with
respect to its employees as set forth in subparagraph (f) of "Retained
Liabilities" in Article IX hereof. It is acknowledged and agreed that the Seller
will be terminating the employment of any such employee that it does not wish to
employ following the Closing Date. Notwithstanding the above, Buyer may, but
shall not be obligated to, discuss employment possibilities with employees of
Seller who have been directly involved in the Acquired Business. Such
discussions will only take place, however, with the prior consent of Seller,
which shall not be unreasonably withheld. Under no circumstances shall the Buyer
contact the following individuals: Tom Braz, Greg Hunt, and Jim O'Rourke. Except
as provided herein, in the event that Buyer should employ any employee of Seller
pursuant to this paragraph, Buyer shall have no liability to Seller arising
therefrom. In addition, Buyer shall have no obligation to continue any the terms
of any employee contract, salary level, employee benefit, vesting, seniority
right or any other matter relating to the employees' employment with Seller.

     It is understood and agreed between the parties that Seller utilized
certain contractors in its conduct of the Acquired Business prior to Closing.
Seller will provide Buyer with the contact and other information regarding such
contractors and will assist Buyer in the continuing utilization of such
contractors in Buyer's business after Closing.

     Except as provided above, for a period of 1 year after the Closing Date,
the Seller and the Buyer shall not, either directly or indirectly (including
through an Affiliate), (a) solicit or attempt to induce any employee or
contractor to terminate his employment or contract with the Seller or the Buyer
or any subsidiary of the Buyer or (b) hire or attempt to hire or otherwise
retain any such employee or contractor; provided, that this clause (b) shall not
apply to any individual whose employment with the Seller, Buyer or a subsidiary
of the Buyer has been terminated for a period of six months or longer. The
Seller and the Buyer shall enforce, for the benefit of the other, all
confidentiality, non-solicitation and non-hiring assignments and similar
agreements between the Seller or the Buyer and any other party which are not
Assigned Contracts.

     6.6 Removal of Inventory and Equipment. The Buyer shall remove all
inventory and equipment that constitute Acquired Assets from the Seller's
premises no later than 60 days after the Closing Date. In the event that Buyer
is unable to remove the Acquired Assets at or before the expiration of 60 days
after the Closing Date, for reasons not caused by Seller, Buyer shall pay rent
in the amount of $500.00 per day for housing such Acquired Assets until they are
removed from Seller's premises. Buyer shall maintain insurance on the inventory
and equipment effective as of the Closing Date, and Seller shall be named as an
additional insured on the Buyer's property loss and casualty insurance. Buyer
shall pay all costs and expenses related to the removal of the inventory and
equipment and shall obtain all other insurance and/or bonding necessary to
remove the inventory and equipment from the premises. Except to the extent
caused by the negligence or intentional


                                       12

<PAGE>

misconduct of the Seller or its agents, under no circumstances shall the Seller
be liable to the Buyer or any third party for any loss, damage or unauthorized
removal of the inventory and equipment. Buyer shall deliver evidence of all
insurance coverage naming the Seller as additional insured prior to the Closing
Date.

     6.7 Retained Assets. The Buyer acknowledges and agrees that the assets set
forth on Schedule 1.1(b) are owned by the Seller and are not acquired by the
Buyer under the terms of this Agreement. In the event that the Seller sells the
assets on the attached Schedule 1.1(b) to a customer after the Closing Date and
the customer requires parts or service on the assets, the Buyer agrees to supply
such parts or service at actual variable cost to be charged to the Seller.

     6.8 Warranty. Buyer accepts any warranty liabilities for products and
services shipped from the Seller prior to the Closing Date; however, in the
event that any portions of sales orders were not shipped prior to the Closing
Date, the Seller retains the responsibility to complete such sales orders. In
the event that the Seller does need to complete a sales order, the Buyer agrees
to supply parts and/or services that are required to complete those orders at
actual variable cost.

     6.9 UCC Termination. Immediately upon Closing, the Seller shall file the
UCC 3 amendment statement with the Secretary of State of the State of Delaware
releasing the liens held in the Acquired Assets by Silicon Valley bank.

                                   ARTICLE VII

                                 INDEMNIFICATION

     7.1 Indemnification by Seller. Seller agrees to indemnify and hold Buyer
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,
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 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


                                       13

<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.

consent;

          (b) the Buyer may terminate this Agreement by giving written notice to
the Seller in the event the Seller is in breach of any representation, warranty

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

          (c) the Seller may terminate this Agreement by giving written notice
to the Buyer in the event the Buyer is in breach of any representation, warranty
or covenant contained in this Agreement, and such breach, individually or in
combination with any other such breach, (i) would cause the conditions set forth
in clauses (c) or (d) of Section 5.3 not to be satisfied and (ii) is not cured
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).
