Stockholder") shall deliver a written notice (the "Offer Notice") to the Company
and to each of the other Stockholders. The Offer Notice will disclose in
reasonable detail the proposed number of Securities to be transferred, the class
or classes and, if applicable, series of such Securities, the proposed price,
terms and conditions of the Transfer and the identity of the transferee. Each of
the other Stockholders may elect to participate in the contemplated sale by
delivering written notice to the Transferring Stockholder within 15 days after
receipt of the Offer Notice. If any of such other Stockholders elects to
participate in such sale (the "Participating Stockholders"), each of the
Transferring Stockholder and the Participating Stockholders will be entitled to
sell in the contemplated sale a number of Eligible Securities of such class and,

which is the number of Eligible Securities of such class and, if applicable,
series (on a fully-diluted basis) held by such Person, and the denominator of

applicable, series (on a fully-diluted basis) owned by the Transferring
Stockholder and the Participating Stockholders, multiplied by (ii) the number of
Eligible Securities of such class and, if applicable, series (on a fully-diluted
basis) to be sold in the contemplated sale.

     For example, if the notice from the Transferring Stockholder contemplated a
     sale of 100 shares of Class C Common Stock by the Transferring Stockholder
     and the Transferring Stockholder at such time owns 300 shares of Class C
     Common Stock

<PAGE>

                                       -9-


     constituting Eligible Securities (on a fully-diluted basis), and if one
     Participating Stockholder elects to participate in such sale and such
     Participating Stockholder owns 100 shares of Class A Common Stock and 100
     shares of Class B Common Stock constituting Eligible Securities (on a
     fully-diluted basis), such Transferring Stockholder would be entitled to
     sell 60 shares of Common Stock (300/500 x 100 shares) and such
     Participating Stockholder would be entitled to sell 40 shares of Common
     Stock (200/500 x 100 shares).

     As a condition to any Transfer by the Transferring Stockholder, the
Transferring Stockholder must obtain the agreement of the prospective
transferee(s) to the participation of all Participating Stockholders in any
contemplated sale and will not transfer any of its Securities to the prospective
transferee(s) if the prospective transferee(s) declines to allow the
participation of the Participating Stockholders on the terms specified herein.

          2.3. Transfers of Securities in Breach of this Agreement. In the event
of any Transfer of Securities in breach of this Agreement, commencing
immediately upon the date of such attempted Transfer (a) such Transfer shall be
void and of no effect, (b) no dividend of any kind or any distribution pursuant
to any liquidation, redemption or otherwise shall be paid by the Company to the
purported transferee in respect of such Securities (all such rights to payment
by the transferring Stockholder and/or the purported transferee being deemed
waived), (c) the voting rights of such Securities, if any, shall terminate, and
(d) neither the transferring Stockholder nor the purported transferee shall be
entitled to exercise any rights with respect to such Securities until such
Transfer in breach of this Agreement has been rescinded.

          2.4. Classes and Series of Securities. Notwithstanding anything herein
to the contrary, for purposes of this Section 2 and Section 5 hereof, all
classes of Common Stock shall be treated as a single class, and each series of
Preferred Stock shall be treated as a separate series.

     Section 3. SALE OF THE COMPANY.

          3.1. Approved Sale. In the event that a Disposition Event is approved
by the Company's Board of Directors and consented to by the Majority FFL Holders
(an "Approved Sale"), each Stockholder hereby waives, to the extent permitted by
applicable law, all rights to object to or dissent from such Approved Sale and
hereby agrees to consent to and raise no objection against such Approved Sale.

          3.2. Obligations of Stockholders. The Company and the Stockholders
hereby agree to cooperate fully in any Approved Sale and not to take any action
prejudicial to or inconsistent with such Approved Sale. Without limiting the
generality of the foregoing, each Stockholder hereby agrees to (i) vote such
Stockholder's Securities to approve the terms of any such Approved Sale and such
matters ancillary thereto as may be necessary in the judgment of the Board of
Directors of the Company to effect such Approved Sale, (ii) waive any appraisal
rights that such Stockholder would have with respect to such Approved Sale,
(iii) in an Approved Sale structured as a sale of stock, sell all of such
Stockholder's Securities on the terms and conditions approved by the Board of
Directors of the Company and (iv) upon request, deliver

such Stockholder's Securities (together with executed instruments of transfer)
in escrow (pending receipt of the purchase price therefor) to counsel for the
Company in such sale.

          3.3. Received Consideration. The obligations of the Stockholders with
respect to any Approved Sale are subject to the satisfaction of the conditions
that (i) upon the consummation of such Approved Sale, all of the sellers of
Common Stock and Series A Preferred Stock, respectively, will receive the same
form and amount of consideration per share of Common Stock or Series A Preferred
Stock, as applicable, or if any such sellers are given an option as to the form
and amount of consideration to be received per share of Common Stock or Series A
Preferred Stock, all holders of Common Stock and Series A Preferred Stock, as
applicable, will be given the same option, (ii) the holders of Common Equity
Rights shall not be required to exercise or convert such Common Equity Rights
prior to or in connection with such Approved Sale, (iii) upon consummation of
such Approved Sale, the sellers of Common Equity Rights that have not been
exercised or converted prior to or in connection with such Approved Sale will
receive the same form and amount of consideration per share of Common Stock as
such seller would have received had such seller exercised or converted such
Common Equity Rights immediately prior to the consummation of such Approved
Sale, provided that the amount of consideration per share of Common Stock shall
be reduced by the exercise or conversion price per share that would have been
payable upon conversion or exercise thereof, (iv) any indemnification
obligations of the sellers shall be several, not joint, and shall (other than
with respect to representations and warranties with respect to enforceability of
any seller's obligations and title to Securities) be pro rata based on the value
of the proceeds received by the sellers in connection with such Approved Sale,
(v) any escrow securing indemnity obligations of the sellers shall be funded by
the Sellers pro rata based on the value of the proceeds received by the sellers
in connection with such Approved Sale and (vi) the aggregate liability of each
seller with respect to indemnification obligations in connection with such
Approved Sale shall be limited to the proceeds received by such seller in
connection with such Approved Sale. It shall be a condition to any Approved Sale
structured as a stock sale that (a) if any consideration will be received in
respect of Common Stock, then the purchaser with respect to such transaction
contemporaneously will purchase all of the outstanding shares of Series A
Preferred Stock and that each holder thereof will receive in respect of such
shares an amount of consideration per share that will have a fair market value
equal to the sum of (A) the liquidation value (as determined by the Charter) per
share of Series A Preferred Stock immediately prior to the consummation of such
Approved Sale plus (B) an amount equal to the product of (x) the number of
shares of Common Stock issuable upon conversion of a share of Series A Preferred
Stock immediately prior to the consummation of such Approved Sale multiplied by
(y) the consideration per share of Common Stock received by the holders of
Common Stock in such Approved Sale, and (b) if the aggregate consideration to be
received in respect of all outstanding shares of Series A Preferred Stock in
connection with such Approved Sale will have a fair market value that is less
than the aggregate liquidation values (as determined by the Charter) of all of
the outstanding shares of Series A Preferred Stock immediately prior to the
consummation of such Approved Sale, then the holders of Series A Preferred Stock
will receive a proportionate amount per share (based upon the respective
liquidation values (as determined by the Charter) of the outstanding shares of
Series A Preferred Stock immediately prior to the consummation of such Approved
Sale).

          3.4. Proxy. Each Stockholder hereby appoints the Majority FFL
Stockholders as such Stockholder's true and lawful proxy and attorney in
connection with any Approved Sale, with full power of substitution, to vote all
Voting Securities owned by such Stockholder or over which such Stockholder has
voting control to effectuate the agreements set forth in this Section 3 in the
event of any breach by such Stockholder of its obligations under this Section 3.
The proxies and powers granted by each Stockholder pursuant to this Section 3.4
are coupled with an interest and are given to secure the performance of such
Stockholder's duties under this Section 3. Such proxies are irrevocable for so
long as this Section 3 remains in effect and will survive the death,
incompetence or disability of any Stockholder who is an individual and the
merger, liquidation or dissolution of any Stockholder that is a corporation,
limited liability company, partnership or other entity.

     Section 4. BOARD OF DIRECTORS.

          4.1. Boards of Directors; Voting Agreements. (a) In any and all
elections of directors of the Company (whether at a meeting or by written
consent in lieu of a meeting), each Stockholder shall vote, or cause to be
voted, or cause such Stockholder's designees as directors to vote, all Voting
Securities owned by such Stockholder or over which such Stockholder has voting
control so as to fix the number of directors of the Company at five (5), and to
nominate and elect such five (5) directors of the Company as follows:

          (i) two (2) individuals designated by the Majority Class C Holders,
     who shall initially be Spencer C. Fleischer and Caleb Everett, shall
     constitute the Class C Directors pursuant to Part B, Section 2(d) of
     Article Fourth of the Charter and shall each be entitled to that number of
     votes determined pursuant to Part B, Section 2(d) of Article Fourth of the
     Charter;

          (ii) one (1) individual designated by the Majority Green Mountain
     Holders so long as the Green Mountain Investor and its Affiliates own, in
     the aggregate, five percent (5%) or more of the then outstanding shares of
     Common Stock (on a fully-diluted basis), who shall initially be Guy
     Roberts, shall constitute a Class A Director pursuant to Part B, Section
     2(d) of Article Fourth of the Charter and shall each be entitled to one (1)
     vote;

          (iii) one (1) individual designated by the Majority Fulham Holders so
     long as the Fulham Investors and their Affiliates own, in the aggregate,
     five percent (5%) or more of the then outstanding shares of Common Stock
     (on a fully-diluted basis), who shall initially be Tim Fulham, shall
     constitute a Class A Director pursuant to Part B, Section 2(d) of Article
     Fourth of the Charter and shall each be entitled to one (1) vote; and

          (iv) Dale Glomsrud, so long as he continues to be employed by the
     Company as Chief Executive Officer, and thereafter, his successor as Chief
     Executive Officer of the Company, shall constitute a Class A Director
     pursuant to Part B, Section 2(d) of Article Fourth of the Charter and shall
     be entitled to one (1) vote.

          (b) If any vacancy shall occur in the Board of Directors of the
Company as a result of death, disability, resignation or any other termination
of a director, the replacement for such vacating director shall be designated by
the Person or Persons who originally designated

<PAGE>


                                      -12-


such vacating director. The Person or Persons entitled to designate a director
or a replacement for a director pursuant to this Section 4.1 shall also be
entitled to designate the removal of such director, with or without cause. Each
Stockholder hereby agrees to vote or cause to be voted or cause such
Stockholder's designees as directors to vote all Voting Securities owned by such
Stockholder or over which such Stockholder has voting control so as to comply
with this Section 4.1(b).

          4.2. PROXY. EACH STOCKHOLDER HEREBY GRANTS TO THE MAJORITY FFL HOLDERS
AN IRREVOCABLE PROXY, COUPLED WITH AN INTEREST, TO VOTE ALL OF THE VOTING
SECURITIES OWNED BY SUCH STOCKHOLDER OR OVER WHICH SUCH STOCKHOLDER HAS VOTING
CONTROL TO THE EXTENT NECESSARY TO CARRY OUT THE PROVISIONS OF THIS SECTION 4 IN
THE EVENT OF ANY BREACH BY SUCH STOCKHOLDER OF HIS, HER OR ITS OBLIGATIONS UNDER
THE VOTING AGREEMENT CONTAINED HEREIN.

          4.3. Action by Stockholders. Each Stockholder further agrees that such
Stockholder will not vote any Voting Securities owned by such Stockholder or
over which such Stockholder has voting control, or take any action by written
consent, or take any other action as a stockholder of the Company, to circumvent
the voting arrangements required by this Section 4. Without limiting the
generality of the foregoing, each Stockholder agrees not to vote any Voting
Securities owned by such Stockholder or over which such Stockholder has voting
control, or take any other action as a stockholder of the Company, to approve
any corporate action or transaction by the Company not previously approved by
the Board of Directors of the Company elected in accordance with this Section 4
and the By-Laws of the Company.

          4.4. Expense Reimbursement. The Company hereby agrees to pay all
reasonable expenses incurred by the directors designated pursuant to this
Section 4 in connection with their attendance at meetings of the Board of
Directors of the Company and its Subsidiaries (including all travel and lodging
expenses related thereto).

     Section 5. LIMITED FIRST REFUSAL RIGHTS.

          5.1. Pre-Emptive Rights. Except for the issuance of Company Equity
Securities (i) pursuant to a Public Sale, (ii) as consideration for the
acquisition of all or any substantial portion of the assets or all or any
portion of the capital stock of any Person, (iii) upon conversion of Preferred
Stock or Common Stock of another class, (iv) upon conversion or exercise of any
Common Equity Rights, (v) pursuant to any Stock Option or any other management
stock option plan or any other issuance of shares of Preferred Stock or Common
Stock to any employee, director, officer or consultant of the Company or any of
its Subsidiaries, (vi) as partial consideration for any debt financing extended
to the Company or any of its Subsidiaries or (vii) with respect to which the
Major Holders have waived their rights to purchase any securities, if the
Company authorizes the issuance and sale of any Company Equity Securities (other
than as a dividend on the outstanding Common Stock or Preferred Stock), the
Company will first offer to sell to each Major Holder a pro rata portion of such
securities equal to the percentage determined by dividing (i) the Invested
Capital Amount of such Major Holder, by (ii) the sum of the Invested Capital
Amounts for all Major Holders. Each such Major Holder
<PAGE>

                                      -13-


will be entitled to purchase all or part of such stock or securities at the same
price and on the same terms as such stock or securities are to be offered to any
other Persons. In the event of a sale of capital stock of the Company in units
consisting of shares of Common Stock and shares of Preferred Stock, each
Stockholder exercising any rights under this Section 5.1 shall be required to
purchase units of shares of Preferred Stock and Common Stock in the same ratio
as is proposed to be sold in such offering.

          5.2. Stockholders' Exercise of Right. Each Stockholder entitled to
purchase securities under this Section 5 must exercise such Stockholder's
purchase rights hereunder within 20 days after receipt of written notice from
the Company describing in reasonable detail the stock or securities being
offered, the purchase price thereof, the payment terms, and such Stockholder's
percentage allotment.

          5.3. Company's Exercise of Right. Upon the expiration of the offering
period described above, the Company will be free to sell such stock or
securities which the Stockholders entitled to purchase such stock or securities
have not elected to purchase during the 180 days following such expiration on
terms and conditions no more favorable to the purchasers thereof, in the
aggregate, than those offered to such Stockholders. Any stock or securities
offered or sold by the Company after such 180-day period must be re-offered to
the Stockholders entitled to purchase such stock or securities pursuant to the
terms of this Section 5.

     Section 6. ADDITIONAL LEGEND. So long as any Securities are subject to the
provisions hereof, all certificates or instruments representing Securities will
have imprinted on them the following legend:

     The shares represented by this certificate are subject to the terms of a
     certain Stockholder Agreement, dated as of August 29, 2003, among the
     issuer of this certificate and certain stockholders. The Stockholder
     Agreement contains certain restrictive provisions relating to the voting
     and transfer of shares of the stock represented hereby. A copy of the
     Stockholder Agreement is on file at the Company's principal offices. Upon
     written request to the Company's Secretary, a copy of the Stockholder
     Agreement will be provided without charge to the holder of this
     certificate.

     Section 7. SEVERABILITY. Whenever possible, each provision of this
Agreement will be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be invalid,
illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not affect
any other provision or any other jurisdiction, but this Agreement will be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein.

     Section 8. ENTIRE AGREEMENT. Except as otherwise expressly set forth
herein, this document embodies the complete agreement and understanding among
the parties hereto with respect to the subject matter hereof and thereof and
supersedes and preempts any prior understandings, agreements or representations

rights under this Agreement specifically (without posting a bond or other
security), to recover damages by reason of any breach of any provision of this

any breach of the provisions of this Agreement and that any Stockholder shall
have the remedy of specific performance and/or injunctive relief in order to
enforce or prevent any violation of the provisions of this Agreement. In the

any provision of this Agreement will be effective against the Company or the
Stockholders unless such modification, amendment or waiver is approved in
writing by the Majority Class C Holders and the holders of at least fifty-one
percent (51%) of the total number of then outstanding shares of Common Stock
constituting Securities then held by all Stockholders; provided, however, that
no amendment, modification or waiver of any provision of this Agreement that
adversely affects the rights of one particular Party (as hereinafter defined) to

<PAGE>

waiver of such provisions and will not affect the right of such party thereafter
to enforce each and every provision of this Agreement in accordance with its
terms.

     Section 14. EMPLOYMENT. Nothing contained in this Agreement is intended to
create for any Stockholder who is an officer, employee or director of the

     Section 18. CONSTRUCTION. The language used in this Agreement will be
deemed to be the language chosen by the parties to express their mutual intent,

calculations of the Company's equity or any type, class or series thereof "on a
fully diluted basis" or as "fully diluted" or similar terms shall mean such
equity or type, class or series thereof at any date as diluted by the issuance
of all shares of such equity or type, class or series thereof then issuable upon
the exercise or conversion of all then outstanding and exercisable warrants,
options or convertible securities pursuant to which the Company is then
obligated to issue such equity or type, class or series thereof, but
specifically excluding all shares issuable under warrants, options or
convertible securities which are not then exercisable or convertible. Anything
to the contrary notwithstanding, any calculation of "fully-diluted" Common Stock
or Class C Common Stock under this Agreement shall, at any time of
determination, include the number of shares of Class C Common Stock into which
the outstanding shares of Series A Preferred Stock are then convertible whether
or not such shares are required to be converted by the Corporation at such time.

                    AMENDMENT NO. 2 TO STOCKHOLDER AGREEMENT

               AMENDMENT NO. 2 TO STOCKHOLDER AGREEMENT, dated as of September
     24, 2004 (this "Amendment"), by and among Chief Manufacturing Holding
     Corp., a Delaware corporation (the "Company"), and the stockholders of the
     Company listed on the signature pages hereto (the "Stockholders").

               WHEREAS, the Company and the Stockholders have entered into a
Stockholder Agreement, dated as of August 29, 2003 (as amended, supplemented or
otherwise modified to the date hereof, the "Stockholder Agreement"); and

               WHEREAS, the Stockholders desire to amend the Stockholder
Agreement in certain respects as set forth herein; and

               NOW, THEREFORE, in consideration of the foregoing premises, and
for other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties hereto hereby agree as follows:

          1. DEFINITIONS. Each capitalized term used in this Amendment and not
otherwise defined herein shall have the same meaning herein as in the
Stockholder Agreement.

          2. AMENDMENTS TO STOCKHOLDER AGREEMENT. Each of the following
amendments to the Stockholder Agreement shall be effective as of the Effective
Date (as defined in Section 5 below):

               (a) Section 1 of the Stockholder Agreement is hereby amended by
     deleting in its entirety the definition "Major Holder" set forth in such
     Section.

               (b) Section 5 of the Stockholder Agreement is hereby amended and
     restated to read in its entirety as follows:

               "5.1 Pre-Emptive Rights. Except for the issuance of Company
          Equity Securities (i) pursuant to a Public Sale, (ii) as consideration
          for the acquisition of all or any substantial portion of the assets or
          all or any portion of the capital stock of any Person, (iii) upon
          conversion of Preferred Stock or Common Stock of another class, (iv)
          upon conversion or exercise of any Common Equity Rights, (v) pursuant
          to any Stock Option or any other management stock option plan or any
          other issuance of shares of Preferred Stock or Common Stock to any
          employee, director, officer or consultant of the Company or any of its
          Subsidiaries or (vi) as partial consideration for any debt financing
          extended to the Company or any of its Subsidiaries, if the Company
          authorizes the issuance and sale of any Company Equity Securities
          (other than as a dividend on the outstanding Common Stock or Preferred
          Stock), the Company will first offer to sell to each Stockholder a pro
          rata portion of such securities equal to the percentage determined by
          dividing (a) the number of shares of Common Stock then held by such
          Stockholder (determined on a fully-diluted basis), by (b) the
          aggregate number of shares of Common Stock then outstanding
          (determined on a fully-diluted basis). Each Stockholder will be

<PAGE>

                                       -2-


          entitled to purchase all or part of such stock or securities at the
          same price and on the same terms as such stock or securities are to be
          offered to any other Persons. In the event of a sale of capital stock
          of the Company in units consisting of shares of Common Stock and
          shares of Preferred Stock, each Stockholder exercising any rights
          under this Section 5.1 shall be required to purchase units of shares
          of Preferred Stock and Common Stock in the same ratio as is proposed
          to be sold in such offering.

               5.2 Stockholders' Exercise of Right. Each Stockholder entitled to
          purchase securities under this Section 5 must exercise such
          Stockholder's purchase rights hereunder within 20 days after receipt
          of written notice from the Company describing in reasonable detail the
          stock or securities being offered, the purchase price thereof, the
          payment terms, and such Stockholder's percentage allotment. If all of
          the securities offered to the Stockholders are not fully subscribed
          for by the Stockholders, the securities which are not so subscribed
          for will be reoffered to the Stockholders purchasing their full
          allotment upon the terms set forth in this Section 5, except that such
          Stockholders must exercise their purchase rights within five (5) days
          after receipt of such reoffer.

               5.3 Company's Exercise of Right. Upon the expiration of the
          offering period described above, the Company will be free to sell such
          stock or securities which the Stockholders have not elected to
          purchase during the 180 days following such expiration on terms and
          conditions no more favorable to the purchasers thereof, in the
          aggregate, than those offered to the Stockholders. Any stock or
          securities offered or sold by the Company after such 180-day period
          must be re-offered to the Stockholders pursuant to the terms of this
          Section 5.

               5.4. Classes of Securities. Notwithstanding anything herein to
          the contrary, for purposes of this Section 5, all classes of Common
          Stock shall be treated as a single class."

          3. COUNTERPARTS. This Amendment may be executed in any number of
counterparts (including by facsimile), each of which when so executed shall be
deemed to be an original and all of which taken together shall constitute one
and the same agreement.

          4. GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with the laws of The Commonwealth of Massachusetts.

          5. EFFECTIVENESS OF AMENDMENT. This Amendment shall become effective
as of the date hereof (the "Effective Date") upon execution of counterparts of
this Amendment by Stockholders constituting the Majority Class C Holders and the
holders of at least fifty-one percent (51%) of the total number of outstanding
shares of Common Stock constituting Securities held by all Stockholders.
Notwithstanding the foregoing, if the "Closing" does not occur under (and as
defined in) the Stock Purchase Agreement, dated as of the date hereof, among
Chief Manufacturing, Inc., a Massachusetts corporation and a wholly-owned
subsidiary of the Company, Decade Industries, Inc. (d/b/a Sanus Systems), a
Minnesota corporation ("Sanus"), the stockholders of Sanus and the "Seller
Representative" named therein, within two (2) days after the Effective Date,
this Amendment shall immediately become null and void and

<PAGE>

                                       -3-


shall be of no further force or effect, without a need for any consent or
further action on the part of the Company, any of the Stockholders or any other
person or entity.

          6. RATIFICATION. Except as otherwise expressly provided by this
Amendment, the Stockholder Agreement and all documents, instruments and
agreements related thereto are hereby ratified and confirmed in all respects and
shall continue in full force and effect.
