                         EXECUTIVE EMPLOYMENT AGREEMENT

            This EXECUTIVE AGREEMENT (this "Agreement") is made as of July 1,
2000, by and between Aavid Thermal Technologies, Inc., a Delaware corporation
(the "Company"), Fluent Holdings, Inc., a Delaware corporation ("Fluent"), and
Aavid Thermalloy, LLC, a Delaware limited liability company ("AT"), and John W.
Mitchell ("Executive"). Fluent and AT are subsidiaries of the Company and are
individually referred to as a "Subsidiary" and collectively referred to as the
"Subsidiaries." Certain other definitions are set forth in Section 9 of this
Agreement.

            Executive desires to be employed by the Company and the
Subsidiaries, and the Company and the Subsidiaries desire to employ Executive
and to be assured of their right to have the benefit of Executive's services on
the terms and subject to the conditions set forth in this Agreement. Executive
is also purchasing certain shares of stock of the Company's affiliates pursuant
to a Coinvest Securities Purchase Agreement dated as of the date of this
Agreement and a Vesting Securities Purchase Agreement dated as of the date of
this Agreement (the "Securities Purchase Agreements"), and is entering into
certain other agreements in connection with such securities purchases. The
Company, Subsidiaries and Executive desire to enter into this Agreement (i)
setting forth the terms and conditions of Executive's employment with the
Company and the Subsidiaries; and (ii) setting forth the obligation of Executive
to refrain from competing with the Company and its Affiliates (as defined below)
under certain circumstances as provided herein.

            NOW, THEREFORE, the parties hereto agree as follows:

      1. Employment. The Company and each Subsidiary shall employ Executive, and
Executive by this Agreement accepts employment with the Company and each
Subsidiary, upon the terms and conditions set forth in this Agreement for the
period beginning on the date hereof and ending as provided in Section 4 hereof
(the "Employment Period").

      2. Position and Duties.

      (a) During the Employment Period, Executive shall serve as the Vice
President and General Counsel of the Company and of each Subsidiary.

      (b) Executive shall report to the Chief Executive Officer of the Company
and each Subsidiary, and Executive shall devote Executive's best efforts and
Executive's full business time and attention (except for permitted vacation
periods, periods of illness or other incapacity, reasonable time spent with
respect to civic and charitable activities (provided that none of such
activities shall interfere with Executive's duties to the Company and the
Subsidiaries); and other permitted absences for which senior executive employees
of the Company are generally eligible from time to time under the Company's
policies) to the business and affairs of the Company, the Subsidiaries and the
Company's Affiliates. Executive shall perform Executive's duties and
responsibilities to the best of Executive's abilities in a diligent,
trustworthy, businesslike and efficient manner.
<PAGE>
      3. Base Salary; Benefits and Bonuses.

      (a) During the Employment Period, Executive's base salary shall be
$210,000 per annum, or such higher rate as the Board of the Company may
designate from time to time (the "Base Salary"), which salary shall be payable
in regular installments in accordance with the Company's general payroll
practices and shall be subject to customary withholding.

      (b) In addition to the Base Salary, during the Employment Period,
Executive shall be eligible to receive an annual bonus (the "Bonus") determined
by the following formula: "% times % times T", where "%" is the percentage of
the Company's target EBITDA actually achieved by the Company during a particular
fiscal year and "T" is 33 1/3% of Executive's Base Salary during such fiscal
year. For purposes of this Agreement, the Company's target EBITDA shall be
determined prior to the beginning of each fiscal year by the Company's Board of
Directors in good faith, providing Executive with a reasonable opportunity to
earn the Bonus; provided that the Company's target EBITDA for 2000 shall be
$50.238 million. Any such Bonus, if determined by the Company to be payable,
shall be payable within 90 days following the end of each fiscal year (provided
that the first fiscal year for which the Bonus will be paid will be the year
beginning January 1, 2000) during the Employment Period. Notwithstanding the
forgoing, no Bonus shall be due or payable unless the EBITDA actually achieved
by the Company during a particular fiscal year is at least 90% of the target
EBITDA for such year.

      (c) During the Employment Period, Executive shall be entitled to
participate in all of the Company's and each Subsidiary's employee benefit plans
and programs for which senior executive employees of the Company and each
Subsidiary are generally eligible (without duplication), which shall include,
but shall not be limited to, health insurance, dental insurance, life insurance,
disability insurance and participation in the Company's 401(k) plan. Executive's
right to participate in any employee benefit plans or programs of the Company
and each Subsidiary shall be subject to the right of the Company and each
Subsidiary to amend, modify or terminate any such plan or program in accordance
with its terms and applicable law and subject in each case to any applicable
waiting periods or other restrictions contained in such benefit plans or
programs. During the Employment Period, Executive shall be eligible for four
weeks per year of paid vacation in accordance with the policies of the Company.
The maximum amount of vacation time that Executive shall be permitted to carry
over from one year to the next shall be equal to eight weeks.

      (d) The Company or a Subsidiary shall reimburse Executive for all
reasonable business expenses incurred by Executive in the course of performing
Executive's duties under this Agreement which are consistent with the Company's
policies in effect from time to time with respect to travel, entertainment and
other business expenses, subject to the Company's requirements with respect to
reporting and documentation of such expenses.

      4. Term; Termination; Severance.

      (a) The Employment Period shall be for a period of five years from the
date hereof; provided that (i) the Employment Period shall terminate prior to
such date upon Executive's death or Incapacity; (ii) the Employment Period may
be terminated by the Company at any time prior to such date with Cause or
without Cause; and (iii) the Employment Period may be terminated by Executive at
any time for any reason


                                      -2-
<PAGE>
(a "Voluntary Termination"). Any termination of the Executive's employment with
the Company shall be a "Termination." The date of any termination of Executive's
employment with the Company shall be the "Termination Date."

      (b) Upon any Termination, Executive shall be entitled to receive
Executive's Base Salary earned through Executive's Termination Date, prorated on
a daily basis together with all accrued but unpaid vacation time earned by
Executive during the fiscal year in which such Termination occurs. Except as set
forth in Section 4(d), Executive shall not be entitled to receive Executive's
Base Salary or any bonuses or other benefits from the Company or any Subsidiary
for any period after the Termination Date.

      (c) In the event Executive's employment is terminated by the Company with
Cause, upon a Voluntary Termination other than for Good Reason or upon
Executive's death or Incapacity, the Company and the Subsidiaries shall have no
obligation to make any severance or other similar payment to or on behalf of
Executive.

      (d) In the event that Executive's employment is terminated by the Company
without Cause or by Executive for Good Reason, following such Termination and
upon execution by Executive of a general release on employment matters in favor
of the Company, each Subsidiary and their Affiliates, in form satisfactory to
the Company, releasing any and all claims, including claims for payments (other
than those payments due under this Section 4), due to Executive arising under or
pursuant to this Agreement against the Company, each Subsidiary and their
Affiliates as of the Termination Date, the Company shall pay Executive his
annual Base Salary (as in effect on the Termination Date) and provide benefits
equivalent to those provided at the Termination Date until the earlier of (i)
the two-year anniversary of the Termination Date and (ii) the five-year
anniversary of the date of this Agreement. Each severance payment under this
Agreement shall be payable in accordance with the Company's normal payroll
procedures and cycles and shall be subject to withholding of applicable taxes
and governmental charges in accordance with federal and state law. After payment
of the severance amounts described in this Section 4(d), the Company and each
Subsidiary shall have no obligation to make any further severance or other
payment to or on behalf of Executive except as otherwise expressly contemplated
by this Agreement. Notwithstanding the foregoing, in the event that Executive
shall breach any of Executive's obligations under Sections 5, 6 or 7 of this
Agreement, then, in addition to any other rights that the Company or each
Subsidiary may have under this Agreement or otherwise, the Company and each
Subsidiary shall be relieved from and shall have no further obligation to pay
Executive any amounts to which Executive would otherwise be entitled pursuant to
this Section 4.

      5. Confidential Information. Executive acknowledges that by reason of
Executive's duties to and association with the Company, each Subsidiary and
their Affiliates, Executive has had and will have access to and has and will
become informed of Confidential Information (as defined in Section 9 below)
which is a competitive asset of the Company, each Subsidiary and/or their
Affiliates. Executive agrees to keep in strict confidence and not, directly or
indirectly, make known, disclose, furnish, make available or use, any
Confidential Information, except for use in Executive's regular authorized
duties on behalf of the Company, each Subsidiary and their Affiliates (including
their predecessors). Executive acknowledges that all documents and other
property including or reflecting Confidential Information furnished to Executive
by the Company, each Subsidiary or any of their Affiliates or otherwise acquired
or developed by the Company, each Subsidiary or any of their Affiliates or
Executive or known by Executive shall at all times be the property of the
Company, the Subsidiaries and their Affiliates. Executive shall take all
necessary and

                                      -3-
<PAGE>
appropriate steps to safeguard Confidential Information and protect it against
disclosure, misappropriation, misuse, loss and theft. Executive shall deliver to
the Company at the termination of the Employment Period, or at any other time
the Company may request, all memoranda, notes, plans, records, reports, computer
tapes, printouts and software and other documents and data (and copies thereof)
relating to the Confidential Information, Work Product (as defined in Section 9
below) or the business of the Company, each Subsidiary or any of their
Affiliates which Executive may then possess or have under Executive's control.

      6. Inventions and Patents.

      (a) Executive acknowledges that all Work Product (as defined in Section 9
below) is the exclusive property of the Company. Executive by this Agreement
assigns all right, title and interest in and to all Work Product to the Company.
Any copyrightable works that fall within the Work Product will be deemed "works
made for hire" under Section 201(b) of the 1976 Copyright Act, and the Company
shall own all of the rights comprised in the copyright therein; provided,
however, that to the extent such works may not, by operation of law, constitute
"works made for hire," Executive by this Agreement assigns to the Company all
right, title and interest therein.

      (b) Executive shall promptly and fully disclose all Work Product to the
Company and shall cooperate and perform all actions reasonably requested by the
Company (whether during or after the Employment Period) to establish, confirm
and protect the Company's right, title and interest in such Work Product.
Without limiting the generality of the foregoing, Executive agrees to assist the
Company, at the Company's expense, to secure the Company's rights in the Work
Product in any and all countries, including the execution by Executive or
Executive's Affiliates of all applications and all other instruments and
documents which the Company shall deem necessary in order to apply for and
obtain rights in such Work Product and in order to assign and convey to the
Company the sole and exclusive right, title and interest in and to such Work
Product. If the Company is unable because of Executive's mental or physical
incapacity or for any other reason (including Executive's refusal to do so after
request therefor is made by the Company) to secure Executive's signature to
apply for or to pursue any application for any United States or foreign patents
or copyright registrations covering Work Product belonging to or assigned to the
Company pursuant to paragraph 6(a) above, then Executive by this Agreement
irrevocably designates and appoints the Company and its duly authorized officers
and agents as Executive's agent and attorney-in-fact to act for and in
Executive's behalf and stead to execute and file any such applications and to do
all other lawfully permitted acts to further the prosecution and issuance of
patents or copyright registrations thereon with the same legal force and effect
as if executed by Executive. Executive agrees not to apply for or pursue any
application for any United States or foreign patents or copyright registrations
covering any Work Product other than pursuant to this paragraph in circumstances
where such patents or copyright registrations are or have been or are required
to be assigned to the Company.

      7. Non-Compete, Non-Solicitation.

      (a) In further consideration of the compensation to be paid to Executive
under this Agreement and the securities made available for Executive's purchase
under the Securities Purchase Agreements, Executive acknowledges that in the
course of Executive's employment with the Company and its Affiliates, he has
prior to the date of this Agreement, and will during the Employment Period,
become familiar with the Company's and its Affiliates' (and their predecessors')
trade secrets, business plans and business

                                      -4-
<PAGE>
strategies and with other Confidential Information concerning the Company and
its Affiliates and that Executive's services have been and shall be of special,
unique and extraordinary value to the Company and its Affiliates. Therefore,
Executive agrees that, during the Employment Period and for two (2) years
thereafter (such period, the "Noncompete Period"), Executive shall not directly
or indirectly own any interest in, manage, control, participate in (whether as
an officer, director, employee, partner, agent, representative or otherwise),
consult with, render services for, or in any other manner engage in any business
which is, directly or indirectly, competitive with any business that the Company
or its Affiliates engages in or is planning to engage in during the Employment
Period, including but not limited to the business of providing thermal
management products and solutions for electronic products and developing and
marketing computational fluid dynamics software, anywhere in the World. Nothing
herein shall prohibit Executive from being a passive owner of not more than 2%
of the outstanding securities of any class of a corporation which is publicly
traded, so long as Executive has no active participation in the business of any
such corporation.

      (b) During the Employment Period and for two (2) years thereafter,
Executive shall not directly or indirectly through another Person (i) induce or
attempt to induce any employee of the Company or any Affiliate to leave the
employ of the Company or such Affiliate, or in any way interfere with the
relationship between the Company or any Affiliate and any employee thereof, (ii)
hire any person who was an employee of the Company or any Affiliate at any time
during the two year period prior to the termination of the Employment Period,
(iii) call on, solicit or service any customer, supplier, licensee, licensor,
franchisee or other business relation of the Company or any Affiliate in order
to induce or attempt to induce such Person to cease or reduce doing business
with the Company or such Affiliate, or in any way interfere with the
relationship between any such customer, supplier, licensee or business relation
and the Company or any Affiliate (including, without limitation, making any
negative statements or communications about the Company, any Subsidiary or their
Affiliates) or (iv) directly or indirectly acquire or attempt to acquire any
business in the World to which the Company or any of its Affiliates, prior to
the Termination Date, has made an acquisition proposal relating to the possible
acquisition of such business by the Company or any of its Affiliates, or has
planned, discussed or contemplated making such an acquisition proposal (such
business, an "Acquisition Target"), or take any action to induce or attempt to
induce any Acquisition Target to consummate any acquisition, investment or other
similar transaction with any Person other than the Company or any of its
Affiliates.

      8. Enforcement. If, at the time of enforcement of Sections 5, 6 or 7 of
this Agreement, a court shall hold that the duration, scope, or area
restrictions stated herein are unreasonable under circumstances then existing,
the parties hereto agree that the maximum period, scope or geographical area
reasonable under such circumstances shall be substituted for the stated period,
scope or area and that the court shall be allowed and directed to revise the
restrictions contained herein to cover the maximum period, scope and area
permitted by law. Because Executive's services are unique and because Executive
has access to Confidential Information and Work Product, the parties hereto
agree that money damages would not be an adequate remedy for any breach of this
Agreement. Therefore, in the event a breach or threatened breach of this
Agreement, the Company or its successors or assigns may, in addition to other
rights and remedies existing in their favor, apply to any court of competent
jurisdiction for specific performance and/or injunctive or other relief in order
to enforce, or prevent any violations of, the provisions hereof (without posting
a bond or other security). In addition, in the event of an alleged breach or
violation by Executive of Section 7, the Period set forth in such Section shall
be tolled until such breach or violation has been duly cured.

                                      -5-

Executive agrees that the restrictions contained in Section 7 are reasonable and
that Executive has received consideration in exchange therefor.

      11. General Provisions.

      (a) Severability. Whenever possible, each provision of this Agreement
shall 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 shall not affect
any other provision or any other jurisdiction, but

                                      -8-
<PAGE>
this Agreement shall be reformed, construed and enforced in such jurisdiction as
if such invalid, illegal or unenforceable provision had never been contained
herein.

      (b) Complete Agreement. This Agreement, those documents expressly referred
to herein and other documents of even date herewith embody the complete
agreement and understanding among the parties and supersede and preempt any
prior understandings, agreements or representations by or among the parties,
written or oral, which may have related to the subject matter hereof in any way
(including, without limitation, any employment agreement or similar agreement
between the Company, any Subsidiary or their Affiliates and Executive, which is
by this Agreement terminated).

      (c) Counterparts. This Agreement may be executed in separate counterparts,
each of which is deemed to be an original and all of which taken together
constitute one and the same agreement.

      (d) Successors and Assigns. Except as otherwise provided herein, this
Agreement shall bind and inure to the benefit of and be enforceable by
Executive, the Company, Subsidiary and their respective successors and assigns;
provided that the rights and obligations of Executive under this Agreement shall
not be assignable. If the Company sells or transfers control of either of the
Subsidiaries, the parties acknowledge that (i) Company may assign this Agreement
to either Subsidiary, in which case Executive shall cease to serve as an officer
of the Company and the other Subsidiary (provided, however, that the assignee
Subsidiary shall be responsible for all obligations of the Company and the other
Subsidiary, including payment of Salary and Bonus), or (ii) Executive may cease
to serve as an officer of the Subsidiary being sold, which shall not be deemed
to be a breach of this Agreement (provided that the Company and the remaining
Subsidiary shall continue to comply with the provisions of this Agreement
applicable to them).

      (E) GOVERNING LAW. ALL QUESTIONS CONCERNING THE CONSTRUCTION, VALIDITY AND
INTERPRETATION OF THIS AGREEMENT WILL BE GOVERNED BY THE INTERNAL LAW, AND NOT
THE LAW OF CONFLICTS, OF THE STATE OF NEW HAMPSHIRE.

      (f) Arbitration. Except for actions for injunctive relief and actions to
enforce the decision of an arbitrator, each of the parties hereto agrees that in
the event of any dispute arising between or among the parties arising out of or
relating to this Agreement or its breach, such dispute shall be settled by
arbitration to be conducted in Concord, New Hampshire in accordance with the
employment arbitration rules (except as modified below) of the American
Arbitration Association and with the Expedited Procedures thereof (collectively,
the "Rules"). Each of the parties hereto agrees that such arbitration shall be
conducted by a single arbitrator selected in accordance with the Rules; provided
that such arbitrator shall be experienced in deciding cases concerning the
matter which is the subject of the dispute. Each of the parties agrees that in
any such arbitration that pre-arbitration discovery shall be limited to the
greatest extent provided by the Rules, that the award shall be made in writing
no more than 30 days following the end of the proceeding, that the arbitration
shall not be conducted as a class action, that the arbitration award shall not
include factual findings or conclusions of law, and that no punitive damages
shall be awarded. Any award rendered by the arbitrator shall be final and
binding and judgment may be entered on it in any court of competent
jurisdiction. Each of the parties hereto agrees to treat as confidential the
results of any arbitration (including, without limitation, any findings of fact
and/or law made by the arbitrator) and not to disclose such results to any
unauthorized person.

      (g) Remedies. Each of the parties to this Agreement shall be entitled to
enforce its rights under this Agreement specifically. The parties hereto agree
and acknowledge that money damages would not be an adequate remedy for any
breach of the provisions of this Agreement and that any party may in its sole
discretion apply to any court of law or equity of competent jurisdiction
(without posting any bond or deposit) for specific performance and/or other
injunctive relief in order to enforce or prevent any violations of the
provisions of this Agreement.

      (h) Survival. The provisions set forth in Sections 5 through 11 shall
survive and continue in full force and effect in accordance with their terms
notwithstanding any termination of the Employment Period.

      (i) Amendment and Waiver. The provisions of this Agreement may be amended
and waived only with the prior written consent of the Company and Executive.
