[BROOKS AUTOMATION LOGO]           FY04 Management Incentive Plan Program
                                           Terms and Conditions

PURPOSE

The Brooks Automation Management Incentive Plan (MIP) is designed to recognize
and reward managerial performance as tied to the business and financial goals,
as well as individual objectives that ensure alignment to the Brooks Strategic
Plan.

PROCESS

All participating employees will receive a letter of eligibility from their
direct manager. This letter is a commitment of participation in the program in
addition to the targeted cash incentive. All letters will have a working example
of the plan along with this program description. Participants are encouraged to
read and understand the program.

TERMS AND CONDITIONS

The company reserves the right to limit the overall pool of cash available for
distribution to 15% of the actual Operating Income. This means if the
performance funding schedule generates an amount of cash greater than 15% of
actual operating income, then the funding will be rolled back. This ensures the
affordability of plan from a business point of view and a fair return to
shareholders.

Brooks Management retains the discretion to make whatever adjustments it
considers necessary to ensure the motivational impact of the plan and to provide
a fair return to shareholders.

Eligible Employees

The Brooks Management Incentive Plan is limited to selected key management
employees with the following criteria:

      -     Regular full and/or part-time employees, employed for more than one
            quarter of the fiscal year

      -     Employee may participate in only one program, e.g. MIP excludes
            sales incentive employees

Ineligible Employees

      -     Employees employed for less than one quarter

      -     All third party contracted employees

      -     Consultants with contracts are excluded

      -     Employees on an approved LOA or long term disability who have not
            worked at least one full quarter during the fiscal year, and have
            not returned to work on or before the date of payment, except
            employees on an approved Military or Family/Medical leave of absence
            who have worked a continuous quarter and have satisfactory
            performance.

                                           Terms and Conditions

Payment Conditions

Employees must have been assessed as having satisfactory performance for at
least one full quarter during the fiscal year.

Cash Incentive Targets for employees who terminate during the year, also
terminate and may not be allocated to others. However, if a participating
employee terminates and is replaced by a formerly non-participant (ex., employee
is promoted) and or new hire, then a cash incentive target may be developed on a
prorated basis (see prorated payments).

Employees who are employed on the last day of the fiscal year, but who are
terminated prior to the date of payment as part of a downsizing activity may
receive payment.

Employees who are employed for at least one full quarter during the fiscal year,
but who retire prior to the date of payment may receive payment.

In the event of the death of a participating employee, a prorated amount will be
provided to the estate for the period during which the employee was covered
under the plan.

In no case shall an individual employee receive an actual payment greater than
twice the cash incentive target.

Prorated Payments

Employees on long-term disability or Workers Compensation who have worked at
least one full quarter during the fiscal year and have returned to work on or
before the date of payment will receive a prorated payment based on the number
of whole months the employee has worked.

      -     A whole month is credited when the employee works the majority of
            the month.

When a management employee is newly hired in Q1, 2 or 3 and is recommended for
the Brooks FY04 MIP, the cash incentive target should be prorated at the point
of hire and made part of the offer.

If the date of hire is on or prior to the 15th of the month, then full credit of
the month will be given in the proration. If the date of hire is post the 15th
of the month, no credit for that month will be prorated. Proration will commence
with the following month of employment.

Employees hired in Q4 of the fiscal year are not eligible based on the
requirement of working one full quarter.

                                           Terms and Conditions

Payroll Processing

Participants should expect payments under the plan no later than sixty (60) days
of the public announcement of fiscal year end results. This is due to the legal
restraints of the announcement of fiscal year end results to the public, and the
performance assessments/planning of participating individuals.

The following deductions will be taken from the actual payment:

                                 JOSEPH MCGUIRE
                    AMENDED AND RESTATED EMPLOYMENT AGREEMENT

            TWEETER HOME ENTERTAINMENT GROUP, INC., a Delaware corporation,
      whose principal place of business is 40 Pequot Way, Canton, Massachusetts
      02021 ("Employer" or "Tweeter"), and Joseph McGuire, whose address is 35
      Joanna Drive, Foxboro, Massachusetts 02035 ("Employee"), in consideration
      of the mutual promises made herein, hereby agree to enter into this
      Amended and Restated Employment Agreement (this "Agreement") as follows:

                                   ARTICLE 1.
                            TERM OF EMPLOYMENT DUTIES

            1.01. TERM OF EMPLOYMENT. Employer hereby employs Employee and
      Employee hereby accepts employment with Employer for the period beginning
      on July 1, 2004 and ending three (3) years thereafter unless earlier
      terminated pursuant to this Agreement. This Agreement shall be renewed
      automatically for succeeding one (1) year terms unless either party gives
      notice to the other at least 60 days prior to the expiration of any such
      renewal term of such party's intention not to renew. As used herein the
      phrase "employment term" refers to the entire period of employment of
      Employee by Employer hereunder, whether for the periods provided above, or
      whether terminated earlier as hereinafter provided or extended by mutual
      agreement between Employer and Employee.

            1.02. GENERAL DUTIES. Employee shall serve as the Senior Vice
      President ("SVP") and Chief Financial Officer ("CFO") of Tweeter. In his
      capacity as SVP and CFO of Tweeter, Employee shall report to Employer's
      President, and shall do and perform all services, acts, or things, as
      directed by said President or by Tweeter's Board of Directors (the
      "Tweeter Board").

            1.03. NON-COMPETITION AND NON-SOLICITATION. (a) Subject to the other
      provisions of this Section 1.03, during the Restricted Period (as defined
      below), the Employee shall not (whether as an owner, partner, officer,
      director, trustee, agent, employee, consultant, advisor or otherwise), in
      the Restricted Territory (as defined below), directly or indirectly,
      compete with the Employer or engage or participate in the business
      conducted by the Employer or enter into the employ of or provide any
      services to any person engaged in a business that is competitive with the
      business of the Employer. During the Restricted Period, the Employee also
      (i) shall not interfere with, disrupt or attempt to disrupt the
      relationship, contractual or otherwise, between the Employer and any
      customer, supplier, lessor, lessee, employee, consultant or investor of
      the Employer, and (ii) shall not solicit or hire any employee or
      consultant of the Employer. The "Restricted Period" shall mean the
      Employee's employment term, and (A) any period thereafter in which the
      Employer is paying Severance Pay to the Employee, or (B) if Employee is
      terminated for Cause, or if Employee terminates employment (other than by
      expiration of this Agreement) without Good Reason, two (2) years following
      such termination, regardless of the remaining employment term. The
      "Restricted Territory" shall mean the area within fifty (50) miles of any
      retail store owned or operated by Employer (1) from time to time during
      the employment term or (II) with respect to the period following
      Employee's employment, at the time of termination of the Employee's
      employment.

<PAGE>

                  (b) It is the desire and intent of the parties that the
      provisions of this Section 1.03 shall be enforced to the fullest extent
      permissible under the laws and public policies applied in each
      jurisdiction in which enforcement is sought. Accordingly, if any
      particular subsection or portion of this Section 1.03 shall be adjudicated
      to be invalid or unenforceable, this Section shall be deemed amended to
      delete therefrom the portion thus adjudicated to be invalid or
      unenforceable, such deletion to apply only with respect to the operation
      of this Section in the particular jurisdiction in which such adjudication
      is made.

                  (c) In the event of any breach of the provisions of this
      Section 1.03 by the Employee, any and all rights of the Employee following
      termination of employment to receive any payments of Severance Pay
      pursuant to Article 3 hereof shall automatically terminate, but the
      foregoing shall not be construed so as to require repayment by the
      Employee of any such Severance Pay that has been paid to the Employee.

            1.04. INJUNCTIVE RELIEF. The Employee acknowledges and agrees that a
      breach or threatened breach of the provisions of Section 1.03 of this
      Agreement would result in irreparable economic harm to the Employer and
      that a remedy at law for any such breach would be inadequate, and
      therefore, if there is a breach or threatened breach of the provisions of
      Sections 1.03 of this Agreement, the Employer shall be entitled to an
      injunction restraining the Employee from such breach.

                                   ARTICLE 2.
                            COMPENSATION OF EMPLOYEE

            2.01. ANNUAL SALARY. As compensation for the services to be
      performed hereunder, Employee shall receive a salary at the rate of three
      hundred fifty thousand dollars ($350,000.00) per annum, payable at the
      rate of twenty nine thousand one hundred sixty six dollars and sixty five
      cents ($29,166.65 per month); plus such increases, if any, as may be
      determined by the Tweeter Board or by Employer's President. Employee's
      salary shall be payable in accordance with Employer's payroll payment
      policies during his employment term.

            2.02. BENEFITS. Employee shall be eligible to receive such benefits,
      and to participate in such bonus or incentive plans, are as generally made
      available to other senior executives of Employer or as may be specifically
      provided to Employee as determined by Employer or its Compensation
      Committee from time to time. In addition, Employer shall provide Employee
      with a monthly automobile allowance of up to six hundred dollars ($600.00)
      paid to Employee in addition to his salary and other benefits on the first
      of each month.

                                   ARTICLE 3.
                            TERMINATION OF EMPLOYMENT

                  (a) Termination Upon Death or Disability. Employee's death
      shall terminate his employment by Employer. In addition, if Employee

      unable to perform the services required of him under this Agreement and
      such inability to perform continues for a period in excess of one hundred
      twenty (120) days during any twelve month period (whether such disability
      is continuous or

<PAGE>

      discontinuous during such twelve month period), Employer may terminate his
      employment under this Agreement at any time thereafter, provided, however,
      that such disability is continuing at the time of such termination notice.

                  (b)   Termination For "Cause" or With or Without "Good Reason"

                        (i) Cause. Employer may terminate Employee's employment

      misconduct in connection with the performance of the executive's material
      duties under this Agreement, (2) a breach by Employee of any of his
      material duties assigned to him by the Tweeter Board, the CEO or President
      of Tweeter (other than by reason of physical or mental illness) and
      Employee's failure to cure such breach within thirty (30) days of written
      notice thereof, (3) conduct by Employee against the material best
      interests of Tweeter or a material act of common law fraud by Employee

      Employee outside the greater Boston area without Employee's consent, (ii)
      breach by Tweeter of any of its material obligations under this Agreement
      and failure by Tweeter to cure such breach within thirty (30) days of
      notice thereof, (iii) without Employee's consent, a reduction in his title
      from SVP and CFO or of his duties or responsibilities as SVP and CFO, or
      (iii) a Change in Control of Tweeter, as defined below.

      deemed to occur if, the "Incumbent Directors" (as hereinafter defined)
      cease for any reason, including without limitation as a result of a tender
      offer, proxy contest, merger or similar transaction, to constitute at
      least a majority of the Tweeter Board, provided, however, that any person
      becoming a Director of the Company subsequent to such date whose election
      was approved by a vote of at least two-thirds of the Incumbent Directors
      or whose nomination for election was approved by a nominating committee
      comprised of Incumbent Directors shall be deemed an Incumbent Director.
      The "Incumbent Directors" shall mean persons who, as of the date of this
      Agreement, constitute the Tweeter Board and those persons deemed Incumbent
      Directors pursuant to the preceding sentence.

                         (iii) Termination Without Good Reason. Employee may

      successors in interest, shall be entitled to receive any salary, pro rated
      bonuses, and benefits earned by or accrued to Employee and unpaid at the
      date of his death. Additionally, salary will continue to be paid for 60
      days following Employee's death payable to Employee's wife or children.

      irrespective of any disability insurance or other benefits available to
      Employee.

                  (c) Termination for "Cause". In the event of termination of
      employment during the employment term for Cause, Employee shall be
      entitled to receive his salary then in effect and benefits due or to
      become due to him up to the date of termination of employment, and, in the
      case of benefits, as may be mandated by law following termination of
      employment, but Employee shall not be entitled to any other or further
      salary or other compensation, bonuses (whether or not pro rated) or other
      benefits.

                  (d) Termination by Employer Without Cause or by Employee With

      in effect, payable for one (1) year following termination of employment,
      and (ii) Tweeter shall pay Employee, within ninety (90) days of such a
      termination, in cash, an amount equal to the prior year's paid bonus, if
      any. No Severance Pay shall be payable to Employee if his employment
      terminates due to expiration of this Agreement without renewal, provided,
      however, that upon any such expiration Employer may elect, at its option,
      to pay Employee Severance Pay for up to two (2) years following such
      expiration, in which event Employee shall be bound by the provisions of
      Section 1.03 above during the period in which such Severance Pay is paid.
      Severance Pay shall be payable as salary continuation, payable over time
      in the same manner as Employee's salary. Additionally, all stock options
      of Employee under any incentive or stock option plan of Employer or any
      Employer affiliate shall continue to vest during the period in which
      Severance Pay is being paid, subject, however, to the specific terms of
      any option or other agreement or plan relating thereto.

                  (e) Termination by Employee Without Good Reason. In the event
      of a termination of employment by Employee without Good Reason, Employee
      shall be entitled to receive any salary or bonuses earned by or accrued to
      Employee and unpaid at the date of his death, but shall not receive any
      further salary or other compensation hereunder, and without limiting the
      foregoing, in such event, (i) Employee shall receive no Severance Pay,
      (ii) vesting of all stock options and restricted stock shall cease upon
      termination of employment, and (iii) Employee shall receive no payments in
      respect of unvested accrued benefits under any long or short-term
      incentive plan or retirement plan. The foregoing clauses (i) through (iii)
      shall also apply if Employee's employment terminates due to expiration of
      this Agreement, or of a renewal term of this Agreement, without further
      renewal.

                                   ARTICLE 4.
