 RESEARCH AND DEVELOPMENT AGREEMENT








 Section 1 Engagement as Independent Contractor. 
  
 (a) Generally. Subject to the terms and conditions hereof, STI hereby
engages STAG during the Term to perform, on an exclusive basis, research, design, development, testing and other related services relating to the manufacture, installation, servicing, maintenance and marketing generally of powered air purifying
respirators equipment, dual air supply units and other identified respiratory products (the “Services”). 
  
 (b) Duties and Authority. 
  
 (i) All Services shall be performed by STAG in a professional and workman-like manner to the very best of its ability and STAG will devote
such time, energy and skills as are reasonably necessary to the orderly and efficient dispatch of its responsibilities hereunder; provided that, at all times during the Term, STAG commits to retaining the Principal’s full business time,
skill and efforts to the Services (approximately 40 hours per week, on average, consistent with past custom and practice), and to no other business endeavor. Notwithstanding the foregoing, STAG and the Principal may engage in other non-competitive
business activities, provided such activities do not materially interfere or conflict in any respect with the performance of their respective duties hereunder. Subject to the foregoing and the remaining terms of this Agreement, STAG shall be free to
dispose of such portion of its entire time, energy and skill as it is not obligated to devote hereunder, in such manner as it chooses. 
  
 (ii) The Principal shall at all times lead all efforts hereunder and, as such, shall be primarily responsible for the performance of the
Services. During the Term, STAG shall maintain a suitable staff of engineers and other personnel needed to render the Services, consistent with its current custom and practice (including with respect to total man-hours and service level) in
providing Services to STI. The parties acknowledge that, other than the services of the Principal as set forth herein, STAG shall not be required to retain the services of any specific individual employee or personnel hereunder. However, in the
event of the loss of the services of other STAG personnel (e.g., Otto Gossweiler), STAG shall replace such personnel so that the service level commitment set forth in the second sentence of this subsection is fulfilled. STAG may utilize the
assistance of other STAG personnel in performing the Services; provided that, STI reserves the right to pre-approve any proposed assignment or changes, which approval shall not be unreasonably withheld. 
  
 (iii) It is agreed that STAG shall render and perform the
Services to STI as an independent consultant, and not as an employee. As an independent contractor, STAG shall have no right or authority at any time to make any contract or binding promise of any kind on STI’s behalf. STAG, rather than STI,
shall have day-to-day control over the precise scope and details of the Services, subject only to the ultimate approval, of satisfactory progress and completion, by STI; provided however, that in performing the Services, STAG shall consult
with STI on a regular basis and shall comply with the reasonable requests of STI regarding the Services. STAG is responsible for compliance with all applicable laws and regulations relating to the Services.

 (b) Other Personnel Costs; Use of Third Parties. In the event that the
services or resources of any outside consultants, vendors, suppliers or other non-STAG personnel are deemed necessary to perform properly the Services to be rendered hereunder (collectively, the “Third Party Contractors”), the use of any
such Third Party Contractors and the related terms of engagement shall require the prior approval of STI. In no event will STI be charged more than the costs charged to and paid by STAG for such Contractor services. STAG agrees to pass through to
STI any discounts, credits or any other allowances on cost of expenses afforded to STAG. In the event such are afforded to STAG after invoices have been sent or paid by STI, STAG shall credit the amount in full against the next invoice submitted.

materials. 
  
 (e) Invoices. STAG shall invoice STI every

perquisite whatsoever.

 RESEARCH AND DEVELOPMENT AGREEMENT








 
will conform to, and operate in accordance with, any associated specifications. STAG warrants that, to its knowledge, no Deliverable shall violate or
otherwise infringe upon any other party’s patent, copyright, trademark, trade secret or other intellectual property or proprietary right whatsoever.  
  
 Section 5 Indemnification. 
  
 (a) STAG and STI each agree to indemnify, defend and hold harmless the other, its successors and permitted assigns, from and against any and all amounts
payable under any judgment, verdict, court order or settlement for death or bodily injury or the damage to or loss or destruction of any real or tangible personal property to the extent arising out of the indemnitor’s gross negligence, willful
misconduct or intentional acts in the performance of this Agreement; provided that, nothing contained herein shall excuse the gross negligence, willful misconduct or intentional acts of either Party to the other hereunder, for which said
Party shall be fully responsible and indemnify the other Party. 
  
 (b) STAG agrees to indemnify, defend and hold harmless STI, its successors and permitted assigns, from and against any and all amounts payable under any judgment, verdict, court order or settlement to the extent resulting from any
unaffiliated third party allegation that the work performed by STAG under this Agreement willfully or knowingly infringes, misappropriates or otherwise violates such party’s patent, copyright, trademark, trade secret or other intellectual
property or proprietary right whatsoever. The foregoing infringement indemnity expressly does not cover claims arising from: (i) the combination of such systems, materials or work with products or services not provided by STAG; (ii) the
modification of such systems, materials or work performed by any person, other than STAG; or (iii) the use of systems, materials or work performed in a manner not permitted or contemplated hereunder or by another obligation of STI to STAG.

  
 (c) The indemnities in this Section 5 are contingent

of such claim; and (iii) the indemnified Party cooperating with all reasonable requests of the indemnifying Party (at the indemnifying Party’s expense) in defending or settling a claim. The indemnified Party shall have the right, at its
option and expense, to participate in the defense of any suit or proceeding through a counsel of its own choosing. If, however, the defendants in such action include multiple parties hereto and the indemnified Party shall have concluded that there
may be legal defenses available to it that are different from or additional to those available to the indemnifying Party, the indemnified Party shall be entitled to separate counsel, reasonably acceptable to the indemnified Party, which shall be
paid for by the indemnifying Party. In the event that an indemnifying Party undertakes a defense, the counsel chosen to conduct such defense shall be reasonably acceptable to the indemnified Party. The Parties agree to render to each other such
assistance as may reasonably be required in order to ensure the proper and adequate defense of any such action, suit or proceeding. No Party shall make a settlement of any claim for which indemnity is sought without the written consent of the other,
which consent shall not be unreasonably withheld. 
  
 Section 6 Term.

  
 The term of this Agreement will commence immediately and
automatically upon the Closing (as defined in the Merger Agreement) and continue thereafter for a term of four (4) years (the “Initial Term”). Upon expiration of the Initial Term, this Agreement shall automatically renew for
successive one-year periods (each a “Subsequent Term”), unless either: (a) STI provides written notice to STAG of its intent to terminate STAG’s engagement at least ninety (90) days prior to the end of the Initial Term or a
Subsequent Term; or (b) STAG provides written notice to STI of its intent to terminate its engagement at 

  

 RESEARCH AND DEVELOPMENT AGREEMENT








 
least one hundred eighty (180) days prior to the end of the Initial Term or a Subsequent Term, as the case may be, in either of which case this
Agreement shall expire at the end of the then current Initial Term or Subsequent Term. Notwithstanding the foregoing, STAG’s engagement hereunder may be earlier terminated as provided in Section 7 hereof. The term of this Agreement, as in
effect from time to time in accordance with the foregoing, shall be referred to herein as the “Term.” 
  
 Section 7 Termination of Engagement. 
  
 (a) Termination for Cause. STI may, in its discretion, terminate the Term hereunder, with Cause, without prior notice. For purposes of this
Agreement, the term “Cause” shall mean any one or more of the following: 
  
 (i) Dishonesty, theft, misrepresentation, deceit, or fraud in connection with any STAG Party’s performance of its or his duties
hereunder; 
  
 (ii) Dishonesty, theft,
misrepresentation, deceit, or fraud, other than in connection with any STAG Parties’ performance of its or his duties or functions hereunder, provided such actions cause material harm, or potential material harm, to STI, including material harm
to the reputation or functioning of STI, or to the STAG Parties’ ability to fully perform all duties or functions hereunder; 
  
 (iii) a STAG Party’s negligence, incompetence or insubordination, as determined in the good faith, reasonable discretion of STI, to
perform the duties and functions assigned by STI hereunder, provided however, that if the failure is such as may, in the reasonable opinion of STI, be of the nature that the STAG Party were unaware of its failure to perform, STI shall give
notice of such failure, and the STAG Party shall have up to fifteen (15) calendar days to remedy the deficiency to STI’s reasonable satisfaction. In such an event, Cause shall be determined finally by the affirmative vote of a majority of
the entire STI Board of Directors (excluding the Principal, should he then be a member of such Board), acting in good faith and in a manner that is consistent with its fiduciary duties to maximize STI stockholder value, after the STAG Parties have
been provided the opportunity to make a presentation to the Board; 
  
 (iv) At any time prior to or after the execution of this Agreement, the Principal’s conviction for, or plea of nolo contendere to, a charge or commission of a felony or equivalent (e.g., indictable
offense); 
  
 (v) At any time after the execution
of this Agreement, Principal ceases to be a full-time employee of STAG for any reason whatsoever or otherwise be available to perform the Services hereunder other than due to death or Disability; 
  
 (vi) Any knowing or intentional breach of a material
representation, warranty or covenant by Principal with respect to the Transaction; 
  
 (vii) any breach by the STAG Parties of the provisions of Sections 11 - 17 hereof which is either: (A) knowing or willful, or
(B) has caused, or can reasonably be expected to cause STI material economic harm; provided however, that if the breach is such as may, in the reasonable opinion of STI, be of the nature that the STAG Parties were unaware of its breach,
the STAG Parties shall have thirty (30) days following written notice from STI to fully cure the same; or 
  

 RESEARCH AND DEVELOPMENT AGREEMENT








 (viii) Any other conduct engaged in by any of the STAG Parties with the intended purpose
of resulting in harm or detriment to STI including, but not limited to, the diversion of work opportunity away from STI, or competing with STI. 
  
 (b) Termination Upon the Principal’s Death or Disability. The Term shall be terminated immediately and automatically upon the death of the
Principal. The Term may be terminated, at the option of STI, if the Principal shall be rendered incapable of performing the normal duties and functions of his engagement, as determined in the discretion of STI, and by reason of a Disability (as
defined herein). For purposes of this Agreement, “Disability” shall mean any mental or physical condition either: (i) defined to be a “disability” for purposes of eligibility to receive long term disability benefits under
STI’s long term disability insurance policy or contract as may be in effect from time to time for the benefit of employees of STI; or (ii) that impairs the ability of the Principal to perform the normal duties and functions of his
engagement and which can be expected to last, or which has lasted, for a period of six (6) or more consecutive months from the first date of first onset. If the Term is terminated due to the Disability of the Principal, STI shall give thirty
(30) days’ advance written notice to that effect to STAG. If the existence of a Disability hereunder is in dispute, it shall be resolved by a mutually-agreed physician. 
  
 (c) Termination without Cause. STI may terminate the Term without Cause at anytime on ninety (90) days advance
written notice. 
  
 (d) Termination by STAG Party. In
addition to the right set forth in Section 6(b) hereof, a STAG Party may terminate the Term for Cause if STI fails to make payment of any amount due hereunder not the subject of a bona fide dispute and such failure continues uncured for
forty-five (45) days following written notice to STI. 
  
 Section 8
Consequences of Termination. 
  
 (a) Termination without
Cause. In the event of the termination of the Term by STI without Cause, STAG shall be entitled to continue to receive the Consulting Fee for a period of ninety (90) days following the effective date of such termination. Additionally, if
such termination by STI without Cause occurs (i) on or before June 30, 2006, Principal shall be entitled to his proportionate share of the Maximum Earnout Payment payable for 2006 and 2007 regardless of whether there is actual excess
EBITDA for either year; (ii) after June 30, 2006 but before June 30, 2007, Principal shall be entitled to his proportionate share of the Maximum Earnout Payment payable for 2007 regardless of whether there is actual excess EBITDA for
2007. In either case, the Maximum Earnout Payment shall be due and payable at such time it would otherwise be due and payable pursuant to Section 1.7 of the Merger Agreement. The terms “Maximum Earnout Payment” and “EBITDA”
shall have the same meaning as is ascribed to such terms under the Merger Agreement. 
  
 (b) Other Terminations. In the event of the termination of STAG’s engagement hereunder for any reason other than those specified in Section 8(a) hereof, including but not limited
to STAG’s voluntary termination or the death or Disability of the Principal, STAG shall not be entitled to any payments hereunder; provided that, notwithstanding anything to the contrary in this Section 8, in the event
of termination of STAG’s engagement hereunder for any reason, the STAG Parties shall be entitled to payment of any unpaid portion of its Consulting Fee and any other payments required by Section 2 hereof through the effective date of
termination.  
  

 RESEARCH AND DEVELOPMENT AGREEMENT








 Section 9 Additional Consequences of Certain Termination; Liquidated Damages 
  
 (a) If at anytime during any Subsequent Term, any of the STAG Parties
breaches the notice requirements of Section 7(d), or fails to diligently perform his or its responsibilities during that notice period as required thereby, the Parties agree that the STAG Parties shall pay to STI, as liquidated damages for such
breach immediately thereupon, an amount equal to the pro rata portion of the Consulting Fee for the period for which the required notice was not fully given. 
  
 (b) The Parties acknowledge that: (i) the uninterrupted provision of the Services by the STAG Parties throughout the entire Initial Term as required
hereby is both a material inducement to, and a fundamental basis of the bargain for, both: (i) the consummation of the Merger by TVI; and (ii) STI’s agreement to engage STAG hereunder, the level of fees to be paid to, and the duties
and functions assigned to, STAG hereunder. The Parties further acknowledge that: (x) any termination of the Term prior to the expiration of the full Initial Term (“Early Termination”), will cause irreparable, immediate and substantial
economic and other injury and damage to both STI and TVI; (y) in the event of any Early Termination, it will be either extremely difficult or impossible to determine and identify the damages that will be incurred as a result thereof; and
(z) in order for STI and TVI to protect their respective businesses and goodwill, the liquated damages provided for in this Section 9 are reasonable, necessary and appropriate in duration, nature and amount. 
  
 (c) Nothing in this Section shall be construed to limit in any manner
whatsoever any other rights and remedies that STI may have by virtue of any breach of this Agreement including, without limitation, any breach of Sections 11 through 17 hereof, inclusive, each of which is deemed separately and additionally necessary
for the protection of the business and goodwill of STI and its Affiliates. 
  
 Section 10 Insurance. 
  
 During the Term,
STI shall be entitled to maintain, at its cost and for its benefit, such insurance policies and risk management arrangements covering the Services and the STAG Parties’ activities hereunder as STI deems appropriate under the circumstances. The
STAG Parties agree to cooperate fully, at STI’s sole expense, in the acquisition and maintenance of any such policies and arrangements. In the event that such policies can not be obtained directly by STI, the STAG Parties agree to all
cooperate, at STI’s expense, with all reasonable requests of STI including, if permitted by applicable law, obtaining such policies in STAG’s name, with STI being named as a loss payee or other insured.

 Section 17 Breach of Restrictive Covenants; Specific Enforcement; Passive Investments. 
  
 (a) The restrictions contained in Section 9 and Sections 11 through 17
hereof, inclusive, are necessary for the protection of the business and goodwill of STI and its Affiliates and are considered by each of the STAG Parties to be reasonable for such purposes. It is acknowledged that it may be impossible to determine
the monetary damages incurred by the violation of this Agreement by any STAG Party and that any violation of this Agreement will cause irreparable, immediate and substantial injury to STI. Accordingly, each of the STAG Parties agrees that STI will
be entitled, in addition to all other rights and remedies which may be available, to an injunction enjoining and restraining the STAG Parties and any other involved party from committing a violation of this Agreement and each of the STAG Parties
agrees to the issuance and entry of such injunction. In addition, STI will be entitled to such damages as it can demonstrate it has sustained by reason of the violation of this Agreement by any of the STAG Parties and/or others. With specific regard
to the restrictions contained in Section 14 hereof, in the event a court should find that the Restricted Territory should encompass some geographic territory other than all of North America and Europe despite the Parties’ agreement that
such restriction is necessary for the protection of the business and goodwill of STI, the Parties intend that the covenant contained therein shall be construed as a series of separate covenants, one for each city, county, state and country of the
Restricted Territory. In such an event, except for geographic coverage, each such separate covenant shall be deemed identical in terms of the covenant contained therein. 
  
 (b) Notwithstanding the terms of Sections 14 through 16 hereof, inclusive, each of the STAG Parties shall be permitted to be
a passive owner of not more than five percent (5%) of the outstanding stock of a corporation that is publicly traded, so long as such STAG Parties has no active participation in the business of the corporation. 
  
 (c) All payments otherwise to be made by STI to STAG hereunder may be
set-off in accordance with the set-off provisions as set forth in Section 7.5 of the Merger Agreement. 
  
 (d) The Parties acknowledge that the legal rights and protections afforded to STI in Sections 11 through 13 hereof, inclusive, are for the benefit of STI
and extend to, and cover, all of services provided by STAG to STI prior to the execution of this Agreement. Consequently, such provisions shall expressly cover all of STI’s predecessors in interest, by merger or otherwise. 
  
 (e) The Parties acknowledge that STI has entered into this Agreement in
strict reliance upon the terms and conditions contained in Section 9 and Sections 11 through 17 hereof, inclusive, and that the same form an essential basis of the bargain between the parties. Consequently, the parties agree that the terms and
conditions contained in Section 9 and Sections 11 through 17 hereof, inclusive, will survive and apply even if found to have failed of their essential purpose. 
  
 Section 18 No Breach of Prior Agreement. 
  
 The performance of STAG’s duties hereunder will not breach any invention, assignment, proprietary information,
non-competition, confidentiality, or other agreement or understanding with any former employer or other Person, and none of the STAG Parties will not use in the performance of his duties any documents or materials of a former employer that are not
generally available to the public or have not been legally transferred to STI. STI understands
