         6. Intellectual Property.

         (a) Disclosure and Assignment. Employee will promptly disclose in
writing to the Company complete information concerning each and every invention,
discovery, improvement, device, design, apparatus, practice, process, method or
product, whether patentable or not, made, developed, perfected, devised,
conceived or first reduced to practice by Employee, either solely or in
collaboration with others, during the Term, or within six (6) months thereafter,
whether or not during regular working hours, relating either directly or
indirectly to the business, products, practices or techniques of the Company or
any of its Affiliates ("Developments"). Employee, to the extent that he has the
legal right to do so, hereby acknowledges that any and all of the Developments
are the property of the Company and hereby assigns and agrees to assign to the
Company any and all of Employee's right, title and interest in and to any and
all Developments. At the request of the Company, Employee will confer with the
Company and its representatives for the purpose of disclosing all Developments
to the Company as the Company shall reasonably

                                      -5-

request during the period ending one (1) year after termination of Employee's
employment with the Company.

         (b) Opportunity. If during the Term, or within six (6) months
thereafter, Employee develops or conceives of any invention, discovery,
improvement, device, design, apparatus, practice, process, method or product of
any kind or nature whatsoever, whether patentable or not (collectively, an
"Opportunity"), Employee shall as promptly thereafter as practicable disclose
the Opportunity to the Company in writing and in reasonable detail. Within 10
business days following its receipt of Employee's disclosure (before and during
which time Employee shall not disclose the Opportunity to any other person or
entity), the Company shall notify Employee whether the Company believes that the
Opportunity constitutes a Development. If the Company informs Employee that the
Opportunity is not a Development or fails to respond within ten business days to
Employee's disclosure, Employee shall thereafter be free to exploit or pursue
the Opportunity in a manner determined by Employee in Employee's sole
discretion, but in no event shall Employee do so in violation or derogation of
Employee's other obligations under this Agreement. If the Company notifies
Employee that the Opportunity is a Development and Employee disagrees with that
conclusion, the parties' dispute shall be resolved as provided in Section 7,
below, provided that until such dispute is fully and finally resolved Employee
shall not disclose the Opportunity to any other person or entity, or take any
action intended to exploit, further or profit in any way from the Opportunity,
or assist any other person in doing so.

         (c) Limitation on Sections 6(a), 6(b), 6(g) and 6(h). The provisions of
Sections 6(a), 6(b), 6(g) and 6(h) shall not apply to any Development meeting
the following conditions:

                  (i) such Development was developed entirely on Employee's own
         time;

                  (ii) such Development was made without the use of any
         equipment, supplies, facility or trade secret information of the
         Company or any of its Affiliates;

                  (iii) such Development does not relate (A) directly to the
         business of the Company or any of its Affiliates or (B) to the
         Company's, or any of its Affiliate's, actual or demonstrably
         anticipated research or development; and

                  (iv) such Development does not result from any work performed
         by Employee for the Company or any of its Affiliates.

         (d) Assistance of Employee. Upon request and without further
compensation therefor, but at no expense to Employee, and whether during the
Term or thereafter, Employee will do all lawful acts, including but not limited
to, the execution of papers and lawful oaths and the giving of testimony, that,
in the opinion of the Company, may be necessary or desirable in obtaining,
sustaining, reissuing, extending and enforcing United States and foreign
patents, including but not limited to, design patents, on the Developments, and
for perfecting, affirming and recording the Company's, or any of its
Affiliate's, complete ownership and title thereto, and to cooperate otherwise in
all proceedings and matters relating thereto.

<PAGE>   7

         (e) Records. Employee will keep complete, accurate and authentic
accounts, notes, data and records of the Developments in the manner and form
requested by the Company. Such accounts, notes, data and records shall be the
property of the Company, and, upon its request, Employee will promptly surrender
same to it or, if not previously surrendered upon its request or otherwise,
Employee will surrender the same, and all copies thereof, to the Company upon
the conclusion of his employment.

         (f) Obligations, Restrictions and Limitations. Employee understands
that the Company, or its Affiliates, may enter into agreements or arrangements
with agencies of the United States Government, and that the Company, or its
Affiliates, as applicable, may be subject to laws and regulations which impose
obligations, restrictions and limitations on it with respect to inventions and
patents which may be acquired by it or which may be conceived or developed by
employees, consultants or other agents rendering services to it. Employee shall
be bound by all such obligations, restrictions and limitations applicable to any
such invention conceived or developed by him during the Term and shall take any
and all further action which may be required to discharge such obligations and
to comply with such restrictions and limitations.

         (g) Copyrightable Material. All right, title and interest in all
copyrightable material that Employee shall conceive or originate, either
individually or jointly with others, and which arise out of the performance of
this Agreement, will be the property of the Company and are by this Agreement
assigned to the Company along with ownership of any and all copyrights in the
copyrightable material. Upon request and without further compensation therefor,
but at no expense to Employee, and whether during the Term or thereafter,
Employee shall execute all papers and perform all other acts necessary to assist
the Company to obtain and register copyrights on such materials in any and all
countries. Where applicable, works of authorship created by Employee for the
Company in performing his responsibilities under this Agreement shall be
considered "works made for hire," as defined in the U.S. Copyright Act.

         (h) Know-How and Trade Secrets. All know-how and trade secret
information conceived or originated by Employee that arises out of the
performance of his obligations or responsibilities under this Agreement or any
related material or information shall be the property of the Company, and all
rights therein are by this Agreement assigned to the Company.

         (i) Licensed Technical Assistance Agreement. Notwithstanding anything
to the contrary, all work performed by Employee pursuant to the License
Agreement shall be subject to the foregoing provisions; provided, however, that
Employee shall not be required to assign to UTI his right, title and interest in
and to any Developments unrelated to Triplex (as defined in the License
Agreement). Without limiting the generality of the foregoing, it is the parties'
intent that UTI own the entire right, title and interest in and to any
Developments, including but not limited to copyrightable material, know-how and
trade secrets, pertaining to Triplex regardless of whether such Developments
relate in whole or only in part to Triplex, provided, however, that any and all
such Developments shall be deemed to be Licensed Rights (as defined in the
License Agreement) available for use by eVasc under the License Agreement;
provided further that to the extent that any such Development relates in whole
or in part to the intellectual property of any other licensor of eVasc ("Third
Party Licensor Intellectual Property"), UTI shall acquire all right,

                                      -7-
<PAGE>   8

title and interest to such Development (although not to the Third Party Licensor
Intellectual Property).

         7. Settlement of Disputes.

         (a) Arbitration. Except as provided in Section 7(c), any claims or
disputes of any nature between the Company and Employee arising from or related
to the performance, breach, termination, expiration, application or meaning of
this Agreement or any matter relating to Employee's employment and the
termination of that employment by the Company shall be resolved exclusively by
arbitration in Philadelphia, Pennsylvania, in accordance with, as applicable,
the Commercial Arbitration Rules or Rules for Resolution of Employment Disputes
then existing of the American Arbitration Association. In the event of
submission of any dispute to arbitration, each party shall, not later than
thirty (30) days prior to the date set for hearing, provide to the other party
and to the arbitrator(s) a copy of all exhibits upon which the party intends to
rely at the hearing and a list of all persons each party intends to call at the
hearing. The fees of the arbitrator(s) and other costs incurred by Employee and
the Company in connection with such arbitration shall be paid by the party who
or which is unsuccessful in such arbitration.

         (b) Binding Effect. The decision of the arbitrator(s) shall be final
and binding upon both parties. Judgment of the award rendered by the
arbitrator(s) may be entered in any court having jurisdiction thereof.

         (c) Resolution of Certain Claims--Injunctive Relief. Section 7(a) shall
have no application to claims by the Company asserting a violation of Section
4(e) or 6 or seeking to enforce, by injunction or otherwise, the terms of
Section 4(e) or 6. Such claims may be maintained by the Company in a lawsuit
subject to the terms of Section 7(d). Employee acknowledges that it would be
difficult to fully compensate the Company for damages resulting from any breach
by him of the provisions of this Agreement. Accordingly, Employee agrees that,
in addition to, but not to the exclusion of any other available remedy, the
Company shall have the right to enforce the provisions of Section 4(e) or 6 by
applying for and obtaining temporary and permanent restraining orders or
injunctions from a court of competent jurisdiction without the necessity of
filing a bond therefor, and without the necessity of proving actual damages, and
the Company shall be entitled to recover from Employee its reasonable attorneys'
fees and costs in enforcing the provisions of Section 4(e) or 6.

         (d) Venue. Any action at law, suit in equity or judicial proceeding
arising directly, indirectly, or otherwise in connection with, out of, related
to or from this Agreement, or any provision hereof, shall be litigated only in
the courts of the Philadelphia County, Pennsylvania. Employee and the Company
consent to the jurisdiction of such courts over the subject matter set forth in
Section 7(c). Employee waives any right Employee may have to transfer or change
the venue of any litigation brought against Employee by the Company.

         (a) Employee's Representations. Employee hereby represents and warrants
to the Company that (i) the execution, delivery and performance of this

         (a) Entire Agreement. This Agreement (including the exhibits, schedules
and other documents referred to herein) and that certain Non-Competition
Agreement among Employee, UTI and the Company and dated of even date herewith
among contains the entire understanding between the parties hereto with respect
to the subject matter hereof and supersedes any prior understandings, agreements
or representations, written or oral, relating to the subject matter hereof.

         (b) Counterparts. This Agreement may be executed in separate
counterparts, each of which will be an original and all of which taken together
shall constitute one and the same agreement, and any party hereto may execute
this Agreement by signing any such counterpart.

         (c) Severability. Whenever possible, each provision of this Agreement
shall be interpreted in such a 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 under any applicable law or rule, the validity,
legality and enforceability of the other provision(s) of this Agreement will not
be affected or impaired thereby. To the extent that any court concludes that any
provision of this Agreement is void or voidable, the court shall reform such
provision(s) to render the provision(s) enforceable, but only to the extent
absolutely necessary to render the provision(s) enforceable and only in view of
the parties' express desire that the Company be protected to the greatest extent
allowed by law from the misuse or disclosure of confidential information and/or
Developments.

         (d) Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective heirs, personal
representatives and, to the extent permitted by Section 9(e), successors and

         (e) Assignability. Neither this Agreement nor any right, remedy,
obligation or liability arising hereunder or by reason hereof shall be
assignable (including by operation of law) by either party without the prior
written consent of the other party to this Agreement, except that the Company
may, without the consent of Employee, assign its rights and obligations under
this Agreement to any corporation, firm or other business entity with or into
which the Company may merge or consolidate, or to which the Company may sell or
transfer all or substantially all of its assets, or of which fifty percent (50%)
or more of the equity investment and of the voting control is owned, directly or
indirectly, by, or is under common ownership with, the Company. After any such
assignment by the Company, the Company shall be discharged from all further
liability hereunder and such assignee shall thereafter be deemed to be the
Company for the purposes of all provisions of this Agreement including this
Section 9.

         (f) Modification, Amendment, Waiver or Termination. No provision of
this Agreement may be modified, amended, waived or terminated except by an
instrument in writing signed by the parties to this Agreement. No course of
dealing between the parties will modify, amend, waive or terminate any provision
of this Agreement or any rights or obligations of any party under or by reason
of this Agreement. No delay on the part of the Company in exercising any right
hereunder shall operate as a waiver of such right. No waiver, express or
implied, by the Company of any right or any breach by Employee shall constitute
a waiver of any other right or breach by Employee.

         (g) Notices. All notices, consents, requests, instructions, approvals
or other communications provided for herein shall be in writing and delivered by
personal delivery, overnight courier, mail, electronic facsimile or e-mail

corporation (the "Company"), Medical Device Manufacturing, Inc. d/b/a Rivo
Technologies, a Colorado corporation ("Rivo"), and Jeffrey M. Farina
("Employee").

         WHEREAS, Employee is currently employed as the Vice President of
Engineering of the Company;

         WHEREAS, UTI Acquisition Corp., a wholly-owned subsidiary of Rivo has
agreed to purchase all of the issued and outstanding shares of the Company's
capital stock pursuant to the Purchase Agreement by and among UTI Acquisition
Corp., UTI and the shareholder of UTI dated May 31, 2000 (the "Purchase

         WHEREAS, the Company and Rivo desire to retain the services of Employee
subsequent to such purchase of shares of the Company's capital stock, and
Employee desires to be employed by the Company, on the terms and subject to the
conditions set forth in this Agreement.

         NOW, THEREFORE, in consideration of the premises, the mutual agreements
set forth herein and other good and valuable consideration, the receipt and

hereto hereby agree as follows:

Employee accepts such employment and agrees to perform services for the Company

this Agreement.

         (a) Service with the Company. During the Term, Employee agrees to serve
as Vice President of Engineering of the Company and a vice president of Rivo and
to perform such reasonable employment duties as the Board of Directors of the
Company and Rivo shall assign to him from time to time. Employee's services
pursuant to this Agreement shall be performed primarily at the Company's offices
in Collegeville, Pennsylvania or at such other facilities of the Company as the
Company and Employee may agree upon from time to time.

         (b) Performance of Duties. Employee agrees to serve the Company and
Rivo faithfully and to perform Employee's duties and responsibilities to the

services are performed in accordance with the provisions of Section 3 of that

<PAGE>   2

certain License and Technical Assistance Agreement between UTI and eVasc, as
amended from time to time ("License Agreement"), and are charged by and billed
for by UTI in accordance with Section 4 of such License Agreement; provided,
however, that UTI may limit or restrict the provision of such services by
Employee if in UTI's reasonable judgment the performance of such services by
Employee materially detracts from Employee's ability to perform other services
having higher gross margins. Employee hereby confirms that he is under no
contractual commitment inconsistent with his obligations set forth in this
Agreement, and that, during the Term, he will not render or perform services for
any other corporation, firm, entity or person that are inconsistent with the
provisions of this Agreement. Employee hereby further confirms that he has
terminated any existing employment agreement, if any, that he may have had with
the Company, or any other corporation, firm, entity or person, prior to the date
hereof.

         3. Compensation.

The base salary payable to Employee during each year subsequent to the first
year of Employee's employment shall be adjusted pursuant to the Company's
established pay-grade scale as may be amended from time-to-time by the Company's
Board of Directors but in no event shall the base salary for any subsequent year
be less than the base salary in effect for the prior year.

         (b) Bonus. During the Term, Employee shall be eligible to participate
in the Discretionary Bonus Pool and the Variable Bonus Plan as described in the

have been established for the other employees of the Company at the same level
as Employee, to the extent that Employee meets the requirements for each
individual plan. The Company provides no assurances as to the adoption or
continuance of any particular benefit plan or program, and Employee's
participation in any such plan or program shall be subject to the terms,
provisions, rules and regulations applicable thereto.

         (d) Expenses. During the Term, the Company shall reimburse Employee for
all reasonable and necessary out-of-pocket expenses incurred by Employee in the
performance of his duties under this Agreement in accordance with the Company's

         (d) "Disabled" Defined. As used in this Agreement, the term "Disabled"

whatsoever, Employee shall have the right to

                                      -4-
<PAGE>   5

receive compensation at the rate of Employee's then applicable base salary for
any accrued but unused vacation time and any and all benefits due Employee
pursuant to Section 3(b) as of termination.

         (h) "Affiliate" Defined. As used in this Agreement, the term
"Affiliate" of a person or entity means any person or entity controlled by,

         (i) "Good Reason" Defined. As used in this Agreement, the term "Good

the Company, or any of its Affiliates, and a third party or parties, all rights
in such project, program or venture shall belong to the Company or its
Affiliates, as applicable. Except as approved by the Company's Board of
Directors, Employee shall not be entitled to any interest in such project,
program or venture or to any commission, finder's fee or other compensation in
connection therewith other than the compensation to be paid to Employee as
provided in this Agreement. Employee shall not knowingly have any interest,
direct or indirect, in any vendor or customer of the Company or any of its
Affiliates.

         6. Intellectual Property.

         (a) Disclosure and Assignment. Employee will promptly disclose in
writing to the Company complete information concerning each and every invention,
discovery, improvement, device, design, apparatus, practice, process, method or
product, whether patentable or not, made, developed, perfected, devised,
conceived or first reduced to practice by Employee, either solely or in
collaboration with others, during the Term, or within six (6) months thereafter,
whether or not during regular working hours, relating either directly or
indirectly to the business, products, practices or techniques of the Company or
any of its Affiliates ("Developments"). Employee, to the extent that he has the
legal right to do so, hereby acknowledges that any and all of the Developments
are the property of the Company and hereby assigns and agrees to assign to the
Company any and all of Employee's right, title and interest in and to any and
all Developments. At the request of the Company, Employee will confer with the
Company and its representatives for the purpose of disclosing all Developments
to the Company as the Company shall reasonably

                                      -5-
<PAGE>   6

request during the period ending one (1) year after termination of Employee's
employment with the Company.

         (b) Opportunity. If during the Term, or within six (6) months
thereafter, Employee develops or conceives of any invention, discovery,
improvement, device, design, apparatus, practice, process, method or product of
any kind or nature whatsoever, whether patentable or not (collectively, an
"Opportunity"), Employee shall as promptly thereafter as practicable disclose
the Opportunity to the Company in writing and in reasonable detail. Within 10
business days following its receipt of Employee's disclosure (before and during
which time Employee shall not disclose the Opportunity to any other person or
entity), the Company shall notify Employee whether the Company believes that the
Opportunity constitutes a Development. If the Company informs Employee that the
Opportunity is not a Development or fails to respond within ten business days to
Employee's disclosure, Employee shall thereafter be free to exploit or pursue
the Opportunity in a manner determined by Employee in Employee's sole
discretion, but in no event shall Employee do so in violation or derogation of
Employee's other obligations under this Agreement. If the Company notifies
Employee that the Opportunity is a Development and Employee disagrees with that
conclusion, the parties' dispute shall be resolved as provided in Section 7,
below, provided that until such dispute is fully and finally resolved Employee
shall not disclose the Opportunity to any other person or entity, or take any
action intended to exploit, further or profit in any way from the Opportunity,
or assist any other person in doing so.

         (c) Limitation on Sections 6(a), 6(b), 6(g) and 6(h). The provisions of
Sections 6(a), 6(b), 6(g) and 6(h) shall not apply to any Development meeting
the following conditions:

                  (i) such Development was developed entirely on Employee's own
         time;

                  (ii) such Development was made without the use of any
         equipment, supplies, facility or trade secret information of the
         Company or any of its Affiliates;

                  (iii) such Development does not relate (A) directly to the
         business of the Company or any of its Affiliates or (B) to the
         Company's, or any of its Affiliate's, actual or demonstrably
         anticipated research or development; and

                  (iv) such Development does not result from any work performed
         by Employee for the Company or any of its Affiliates.

         (d) Assistance of Employee. Upon request and without further
compensation therefor, but at no expense to Employee, and whether during the
Term or thereafter, Employee will do all lawful acts, including but not limited
to, the execution of papers and lawful oaths and the giving of testimony, that,
in the opinion of the Company, may be necessary or desirable in obtaining,
sustaining, reissuing, extending and enforcing United States and foreign
patents, including but not limited to, design patents, on the Developments, and
for perfecting, affirming and recording the Company's, or any of its
Affiliate's, complete ownership and title thereto, and to cooperate otherwise in
all proceedings and matters relating thereto.

                                      -6-
<PAGE>   7

         (e) Records. Employee will keep complete, accurate and authentic
accounts, notes, data and records of the Developments in the manner and form
requested by the Company. Such accounts, notes, data and records shall be the
property of the Company, and, upon its request, Employee will promptly surrender
same to it or, if not previously surrendered upon its request or otherwise,
Employee will surrender the same, and all copies thereof, to the Company upon
the conclusion of his employment.

         (f) Obligations, Restrictions and Limitations. Employee understands
that the Company, or its Affiliates, may enter into agreements or arrangements
with agencies of the United States Government, and that the Company, or its
Affiliates, as applicable, may be subject to laws and regulations which impose
obligations, restrictions and limitations on it with respect to inventions and
patents which may be acquired by it or which may be conceived or developed by
employees, consultants or other agents rendering services to it. Employee shall
be bound by all such obligations, restrictions and limitations applicable to any
such invention conceived or developed by him during the Term and shall take any
and all further action which may be required to discharge such obligations and
to comply with such restrictions and limitations.

         (g) Copyrightable Material. All right, title and interest in all
copyrightable material that Employee shall conceive or originate, either
individually or jointly with others, and which arise out of the performance of
this Agreement, will be the property of the Company and are by this Agreement
assigned to the Company along with ownership of any and all copyrights in the
copyrightable material. Upon request and without further compensation therefor,
but at no expense to Employee, and whether during the Term or thereafter,
Employee shall execute all papers and perform all other acts necessary to assist
the Company to obtain and register copyrights on such materials in any and all
countries. Where applicable, works of authorship created by Employee for the
Company in performing his responsibilities under this Agreement shall be
considered "works made for hire," as defined in the U.S. Copyright Act.

         (h) Know-How and Trade Secrets. All know-how and trade secret
information conceived or originated by Employee that arises out of the
performance of his obligations or responsibilities under this Agreement or any
related material or information shall be the property of the Company, and all
rights therein are by this Agreement assigned to the Company.

         (i) Licensed Technical Assistance Agreement. Notwithstanding anything
to the contrary, all work performed by Employee pursuant to the License
Agreement shall be subject to the foregoing provisions; provided, however, that
Employee shall not be required to assign to UTI his right, title and interest in
and to any Developments unrelated to Triplex (as defined in the License
Agreement). Without limiting the generality of the foregoing, it is the parties'
intent that UTI own the entire right, title and interest in and to any
Developments, including but not limited to copyrightable material, know-how and
trade secrets, pertaining to Triplex regardless of whether such Developments
relate in whole or only in part to Triplex, provided, however, that any and all
such Developments shall be deemed to be Licensed Rights (as defined in the
License Agreement) available for use by eVasc under the License Agreement;
provided further that to the extent that any such Development relates in whole
or in part to the intellectual property of any other licensor of eVasc ("Third
Party Licensor Intellectual Property"), UTI shall acquire all right,

                                      -7-
<PAGE>   8

title and interest to such Development (although not to the Third Party Licensor
Intellectual Property).

         7. Settlement of Disputes.

         (a) Arbitration. Except as provided in Section 7(c), any claims or
disputes of any nature between the Company and Employee arising from or related
to the performance, breach, termination, expiration, application or meaning of
this Agreement or any matter relating to Employee's employment and the
termination of that employment by the Company shall be resolved exclusively by
arbitration in Philadelphia, Pennsylvania, in accordance with, as applicable,
the Commercial Arbitration Rules or Rules for Resolution of Employment Disputes
then existing of the American Arbitration Association. In the event of
submission of any dispute to arbitration, each party shall, not later than
thirty (30) days prior to the date set for hearing, provide to the other party
and to the arbitrator(s) a copy of all exhibits upon which the party intends to
rely at the hearing and a list of all persons each party intends to call at the
hearing. The fees of the arbitrator(s) and other costs incurred by Employee and
the Company in connection with such arbitration shall be paid by the party who
or which is unsuccessful in such arbitration.

         (b) Binding Effect. The decision of the arbitrator(s) shall be in
writing and shall be final and binding upon both parties. Judgment of the award
rendered by the arbitrator(s) may be entered in any court having jurisdiction
thereof.

         (c) Resolution of Certain Claims--Injunctive Relief. Section 7(a) shall
have no application to claims by the Company asserting a violation of Section
4(e) or 6 or seeking to enforce, by injunction or otherwise, the terms of
Section 4(e) or 6. Such claims may be maintained by the Company in a lawsuit
subject to the terms of Section 7(d). Employee acknowledges that it would be
difficult to fully compensate the Company for damages resulting from any breach
by him of the provisions of this Agreement. Accordingly, Employee agrees that,
in addition to, but not to the exclusion of any other available remedy, the
Company shall have the right to enforce the provisions of Section 4(e) or 6 by
applying for and obtaining temporary and permanent restraining orders or
injunctions from a court of competent jurisdiction without the necessity of
filing a bond therefor, and without the necessity of proving actual damages, and
the Company shall be entitled to recover from Employee its reasonable attorneys'
fees and costs in enforcing the provisions of Section 4(e) or 6.

         (d) Venue. Any action at law, suit in equity or judicial proceeding
arising directly, indirectly, or otherwise in connection with, out of, related
to or from this Agreement, or any provision hereof, shall be litigated only in
the courts of the Philadelphia County, Pennsylvania. Employee and the Company
consent to the jurisdiction of such courts over the subject matter set forth in
Section 7(c). Employee waives any right Employee may have to transfer or change
the venue of any litigation brought against Employee by the Company.

         8. Representations.

         (a) Employee's Representations. Employee hereby represents and warrants
to the Company that (i) the execution, delivery and performance of this

         9. Miscellaneous.

         (a) Entire Agreement. This Agreement (including the exhibits, schedules
and other documents referred to herein) and that certain Non-Competition
Agreement among Employee, UTI and the Company and dated of even date herewith
among contains the entire understanding between the parties hereto with respect
to the subject matter hereof and supersedes any prior understandings, agreements
or representations, written or oral, relating to the subject matter hereof.

         (b) Counterparts. This Agreement may be executed in separate
counterparts, each of which will be an original and all of which taken together
shall constitute one and the same agreement, and any party hereto may execute
this Agreement by signing any such counterpart.

         (c) Severability. Whenever possible, each provision of this Agreement
shall be interpreted in such a 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 under any applicable law or rule, the validity,
legality and enforceability of the other provision(s) of this Agreement will not
be affected or impaired thereby. To the extent that any court concludes that any
provision of this Agreement is void or voidable, the court shall reform such
provision(s) to render the provision(s) enforceable, but only to the extent
absolutely necessary to render the provision(s) enforceable and only in view of
the parties' express desire that the Company be protected to the greatest extent
allowed by law from the misuse or disclosure of confidential information and/or
Developments.

         (d) Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective heirs, personal
representatives and, to the extent permitted by Section 9(e), successors and
assigns.

         (e) Assignability. Neither this Agreement nor any right, remedy,
obligation or liability arising hereunder or by reason hereof shall be
assignable (including by operation of law) by either party without the prior
written consent of the other party to this Agreement, except that the Company
may, without the consent of Employee, assign its rights and obligations under
this Agreement to any corporation, firm or other business entity with or into
which the Company may merge or consolidate, or to which the Company may sell or
transfer all or substantially all of its assets, or of which fifty percent (50%)
or more of the equity investment and of the voting control is owned, directly or
indirectly, by, or is under common ownership with, the Company. After any such
assignment by the Company, the Company shall be discharged from all further
liability hereunder and such assignee shall thereafter be deemed to be the

Section 9.

         (f) Modification, Amendment, Waiver or Termination. No provision of
this Agreement may be modified, amended, waived or terminated except by an
instrument in writing signed by the parties to this Agreement. No course of
dealing between the parties will modify, amend, waive or terminate any provision
of this Agreement or any rights or obligations of any party under or by reason
of this Agreement. No delay on the part of the Company in exercising any right
hereunder shall operate as a waiver of such right. No waiver, express or
implied, by the Company of any right or any breach by Employee shall constitute
a waiver of any other right or breach by Employee.
