                                   WITNESSETH:

                  WHEREAS, UTI Acquisition Corp., a Colorado corporation and
wholly-owned subsidiary of MDMI has entered into that certain Share Purchase

UTI Acquisition Corp. is purchasing from the Sellers all of the outstanding
capital stock of UTI; and

                  WHEREAS, UTI Acquisition Corp. is unwilling to proceed with
the transactions contemplated by the Purchase Agreement (the "Purchase") unless
Cornwell agrees to refrain from engaging in certain activities described herein,
and UTI Acquisition Corp. has conditioned its commitment to proceed with the

Agreement from Cornwell.

                  NOW THEREFORE, in consideration of the mutual promises and
covenants contained herein, the agreement of UTI Acquisition Corp. to consummate
the Purchase, and other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, MDMI, and Cornwell agree as
follows:

                  1. Non-Competition Commitment.

                           (a) Agreement Not to Compete. Cornwell agrees that,
during the Non-Competition Period (as defined below), Cornwell shall not,
directly or indirectly, through an Affiliate (as defined below) or otherwise,
either for the benefit of himself or for the benefit of any other person, firm,
corporation, governmental or private entity, or any other entity of any kind,
without the prior written consent of MDMI and UTI, which consent may be withheld
by MDMI or UTI, in its sole discretion, compete with MDMI, UTI or any Affiliate
of either MDMI or UTI in any manner or capacity (e.g., through any form of
ownership or as an advisor, principal, agent, consultant, partner, joint
venturer, officer, director, stockholder, employee, member of any association or
otherwise) in any phase of the business that MDMI, UTI or any Affiliate of
either MDMI or UTI is conducting during the term of this Agreement or has
specific plans of which Cornwell is aware to conduct business within the
geographical area described in Section 1(b) below that (i) is related to,
similar to or substantially equivalent to Cornwell's capacity with MDMI, UTI or
any Affiliate of either MDMI or UTI, as applicable or (ii) would permit or
require Cornwell to direct, control or have substantial input into the strategy,
marketing or operations of an entity competing with or seeking to compete with
MDMI, UTI or any Affiliate of either MDMI or UTI. Notwithstanding the foregoing,
Cornwell may provide services to eVasc, L.P.

                                      -1-

("eVasc") without violating the terms of this Agreement, provided that such
services are performed in accordance with the provisions of Section 3 of that
certain License and Technical Assistance Agreement between UTI and eVasc, as
amended from time to time, ("License Agreement") and are charged for and billed
by UTI in accordance with Section 4 of the License Agreement. For purposes of
this Agreement, (i) "Affiliate" of a person or entity means any person or entity
controlled by, controlling or under common control with such person or entity;
provided, however, that for purposes of this Agreement, Cornwell and MDMI shall
not be considered Affiliates of each other, (ii) "Control" including the
correlated terms "controlling," "controlled by" and "under common control with,"
shall mean possession, directly or indirectly, of the power to direct or cause
the direction of management or powers whether through ownership of securities or
any partnership or other ownership interest, by contract or otherwise, of a
person or entity and (iii) "Non-Competition Period" shall mean the later of (X)
five (5) years after the date of this Agreement or (Y) one (1) year after the
termination of Cornwell's employment, if any, with MDMI, UTI or any of their
Affiliates (or other arrangement pursuant to which Cornwell provides services to
MDMI, UTI or any of their Affiliates); provided, however, that in the event
Cornwell is terminated without cause (as defined below) or terminates his
employment with good reason (as defined below), the Non-Competition Period shall
be one (1) year following the date of termination; provided, further, that such
Non-Competition Period may be extended beyond that one (1) year period at MDMI's
sole option for up to four (4) successive six (6) month periods if prior to the
applicable extension period MDMI pays Cornwell a lump sum payment in an amount
equal to six (6) months of Cornwell's base salary as such base salary was in
effect at the time of Cornwell's termination. For purposes of this Agreement,
"cause" shall mean the following: (A) Cornwell has breached the provisions of
this Agreement, any material written policy of MDMI, UTI or their Affiliates to
which Cornwell is subject and Cornwell has failed to cure such breach within
thirty (30) days after receipt of written notice of default; (B) Cornwell has
engaged in willful misconduct, including, without limitation, willful failure to
perform Cornwell's duties as an officer or employee of MDMI, UTI or their
Affiliates, and Cornwell has failed to cure such failure or misconduct within
thirty (30) days after receipt of written notice of default; (C) Cornwell has
committed fraud, misappropriation or embezzlement in connection with the
business of MDMI, UTI or their Affiliates or has otherwise breached his
fiduciary duty to thereto; (D) Cornwell has been convicted or has pleaded nolo
contendere to any act constituting a felony under the laws of any state or of
the United States of America, or any crime involving moral turpitude that, in
the reasonable determination of the Board of Directors of MDMI, causes material
harm to MDMI or its Affiliates; or (E) Cornwell abuses illegal drugs, alcohol or
other controlled substances. For purposes of this Agreement, "good reason" shall
mean the following: (F) any involuntary reduction in salary or benefits other
than such reductions as are generally applicable to similarly situated
employees, (G) any non-consensual required relocation of Cornwell's principal
place of employment of a sixty (60) mile radius of the Cornwell's then principal
place of employment that is expected to be permanent or indefinite, provided
that this exception shall not apply to reasonable and necessary business travel
of any duration or (H) any substantial reduction in the scope of Cornwell's
employment duties from such scope of duties as in effect on the date hereof.

                  (b) Geographic Extent of Covenant. The obligations of Cornwell
under Section 1(a) shall apply to any geographic area in which MDMI, UTI or any
Affiliate of either

                                      -2-
<PAGE>   3

MDMI or UTI currently conducts, or at the time of termination or expiration of
Cornwell's employment, if any, with MDMI, UTI or any Affiliate of either MDMI or
UTI, conducts or has specific plans of which Cornwell is aware to conduct
business or provide services. Cornwell hereby acknowledges that the geographic
boundaries, scope of prohibited activities and the time duration of the
provisions of this Section 1 are reasonable and are no broader than necessary to
protect the legitimate business interests of MDMI and UTI, including, without
limitation, the ability of MDMI to realize the benefit of its bargain and enjoy
the goodwill of UTI.

                  (c) Indirect Competition. Cornwell further agrees that, during
the Non-Competition Agreement, he will not, knowingly directly or indirectly,
assist or encourage any other person in carrying out, directly or indirectly,
any activity that would be prohibited by the foregoing provisions of this
Section 1 if such activity were carried out by Cornwell, either directly or
indirectly.

                  (d) Limitation on Covenant. Ownership by Cornwell, as a
passive investment, of less than one percent (1%) of the outstanding shares of
capital stock, outstanding debt instruments or other securities convertible into
capital stock or debt instruments of any corporation listed on a national
securities exchange or publicly traded on any nationally recognized
over-the-counter market shall not constitute a breach of this Section 1.

                  2. No Interference; Nonsolicitation. During the
Non-Competition Period, Cornwell agrees that he shall not take any action to
interfere with the relationships between MDMI, UTI or any Affiliate of either
MDMI or UTI, and their respective suppliers or customers, including, without
limitation, former customers of UTI. During the Non-Competition Period, Cornwell
agrees that he shall not, directly or indirectly through another entity, (a)
induce or attempt to induce any employee or independent contractor of MDMI, UTI
or any Affiliate of either MDMI or UTI to leave the employ of MDMI, UTI or any
Affiliate of either MDMI or UTI, as applicable, (b) hire any person who was an
employee or independent contractor of MDMI, UTI or any Affiliate of either MDMI
or UTI if such person was employed by MDMI, UTI or any Affiliate of either MDMI
or UTI at any time during the one-year period prior to such hiring or (c) induce
or attempt to induce any customer, supplier, licensee or other business relation
of MDMI, UTI or any Affiliate of either MDMI or UTI to withdraw, curtail or
cease doing business with MDMI, UTI or any Affiliate of either MDMI or UTI, as
applicable.

                  3. Confidential Information.

                  (a) Except as permitted or directed by MDMI's Board of
Directors or UTI's Board of Directors, Cornwell agrees not to divulge, furnish
or make accessible to anyone or use in any way (other than in connection with
and in furtherance of Cornwell's work on behalf of UTI or MDMI) any confidential
or secret knowledge or nonpublic information of MDMI, UTI or any Affiliate of
either MDMI or UTI that Cornwell has acquired or become acquainted with prior to
the date of this Agreement, whether developed by Cornwell or by others,
concerning any trade secrets, confidential or secret designs, processes,
formulae, plans, devices or material (whether or not patented or patentable)
directly or indirectly useful in any aspect of the business of MDMI, UTI or any
Affiliate of either MDMI or UTI, any customer or supplier lists, details of

                                      -3-
<PAGE>   4

relationships with customers, vendors, distributors or suppliers, financial
information, details of operation, organization and management, business plans
and strategies, information about employees and agents of MDMI, UTI or any
Affiliate of either MDMI or UTI, any confidential or secret development or
research work of MDMI, UTI or any Affiliate of either MDMI or UTI, any analyses,
records or date generated from any such information of MDMI, UTI or any
Affiliate of either MDMI or UTI, or any other confidential information or secret
aspects of the business of MDMI, UTI or any Affiliate of either MDMI or UTI
(collectively, "Confidential Information"). This Agreement shall not prohibit
Cornwell from complying with any subpoena or court order, provided that Cornwell
shall at the earliest practicable date provide a copy of the subpoena or court
order to the President of MDMI, UTI or any Affiliate of either MDMI or UTI, as
applicable, it being the parties' intention to give MDMI, UTI or any Affiliate
of either MDMI or UTI a fair opportunity to take appropriate steps to prevent
the unnecessary and/or improper use or disclosure of Confidential Information,
as determined by MDMI, UTI or any Affiliate of either MDMI or UTI in its
reasonable judgment.

                  (b) Cornwell acknowledges that the Confidential Information
constitutes a unique and valuable asset of MDMI and/or UTI, represents a
substantial investment of time and expense by MDMI or UTI, as applicable, would
be susceptible to immediate competitive application by a competitor of MDMI or
UTI and that any disclosure or other use of such Confidential Information other
than for the sole benefit of MDMI and/or UTI would be wrong and would cause
irreparable harm to MDMI and/or UTI. Cornwell agrees to refrain from any acts or
omissions that would reduce the value of such Confidential Information to MDMI,
UTI or any Affiliate of either MDMI or UTI. The foregoing obligations of
confidentiality shall not apply to any Confidential Information that
subsequently becomes generally publicly known in the form in which it was
obtained from MDMI, UTI or any Affiliate of either MDMI or UTI, other than as a
direct or indirect result of the breach of this Agreement by Cornwell.

                  (c) Records Containing Confidential Information. "Confidential
Records" means all documents and other records, whether in paper, electronic or
other form, that contain or reflect Confidential Information. All Confidential
Records prepared by or provided to Cornwell are and shall remain the property of
MDMI, UTI or any Affiliate of either MDMI or UTI. Except as permitted or
directed by MDMI's Board of Directors or UTI's Board of Directors, Cornwell
shall not, at any time, directly or indirectly: (i) copy or use any Confidential
Record for any purpose not relating directly to Cornwell's work for MDMI, UTI or
any Affiliate of either MDMI or UTI; or (ii) show, give, sell, disclose or
otherwise communicate any Confidential Record or the contents of any
Confidential Record to any person or entity other than MDMI, UTI or any
Affiliate of either MDMI or UTI or a person or entity authorized by MDMI, UTI or
any Affiliate of either MDMI or UTI, as applicable, to have access to the
Confidential Record in question. Upon the termination of Cornwell's employment,
if any, with MDMI, UTI or any Affiliate of either MDMI or UTI, or upon the
request of MDMI, UTI or any Affiliate of either MDMI or UTI, Cornwell shall
immediately deliver to the designated person (and shall not keep in Cornwell's
possession or deliver to any other person or entity) all Confidential Records
and all other property of MDMI, UTI or any Affiliate of either MDMI or UTI in
Cornwell's possession or control. This Agreement shall not prohibit Cornwell
from complying with any subpoena or court order, provided that Cornwell shall at
the earliest practicable date provide a

                                      -4-
<PAGE>   5

copy of the subpoena or court order to the President of MDMI, UTI or any
Affiliate of either MDMI or UTI, as applicable, it being the parties' intention
to give MDMI, UTI or any Affiliate of either MDMI or UTI a fair opportunity to
take appropriate steps to prevent the unnecessary and/or improper use or
disclosure of Confidential Records, as determined by MDMI, UTI or any Affiliate
of either MDMI or UTI in its reasonable judgment.

                  (d) Third-Parties' Confidential Information. Cornwell
acknowledges that MDMI, UTI or any Affiliate of either MDMI or UTI have received
and in the future will receive from third parties confidential or proprietary
information, and that MDMI, UTI or any Affiliate of either MDMI or UTI must
maintain the confidentiality of such information and use it only for authorized
purposes. Cornwell shall not use or disclose any such information except as
authorized by MDMI, UTI or any Affiliate of either MDMI or UTI, as applicable or
the third party to whom the information belongs.

                  4. Severability Provision. To the extent that any provision of
this Agreement shall be determined to be invalid or unenforceable, such
provision shall be deleted from this Agreement, and the validity and
enforceability of the remainder of this Agreement shall be unaffected. In
furtherance of and not in limitation of the foregoing, it is expressly agreed
that, should the duration or geographical extent of, or business activities
covered by, this Agreement be finally determined to be in excess of that which
is valid or enforceable under applicable law, such provision shall be construed
to cover the maximum duration, extent or activities which may be validly or
enforceably covered. Cornwell acknowledges the uncertainty of the law in this
respect and expressly stipulates that this Agreement shall be construed in a
manner which renders its provisions valid and enforceable to the maximum extent
(not exceeding its express terms) possible under applicable law.

                  5. Remedies. Cornwell acknowledges that it would be difficult
to fully compensate MDMI and UTI for damages resulting from any breach by such
party of the provisions of this Agreement. Accordingly, in the event of any
actual or threatened breach of such provisions, MDMI and UTI shall (in addition
to any other remedies which it may have) be entitled to temporary and/or
permanent injunctive relief to enforce such provisions, and such relief may be
granted without the necessity of proving actual damages. Cornwell further
acknowledges that this Agreement constitutes a material inducement to MDMI to
consummate the transactions contemplated by the Purchase Agreement and that MDMI
will be relying on the enforceability of this Agreement in consummating the
transactions contemplated under the Purchase Agreement.

                  6. Remedies Cumulative. No remedy conferred by any of the
specific provisions of this Agreement is intended to be exclusive of any other
remedy, and each and every remedy shall be cumulative and shall be in addition
to every other remedy given hereunder or now or hereafter existing at law or in
equity or by statute or otherwise. The election of any one or more remedies by
any party hereto shall not constitute a waiver of the right to pursue other
available remedies.

                                      -5-

                  7. Complete Agreement. This Agreement constitutes the entire
agreement, and supersedes all other prior and contemporaneous agreements and
undertakings, both written and oral, among the parties hereto relating to the
subject matter hereof. There are no representations, warranties, covenants,
statements, conditions, terms or obligations, other than those contained herein,
relating to the subject matter hereof. No amendments or modifications to or
variations of this Agreement shall be deemed valid unless in writing and
executed by MDMI, UTI and Cornwell.

                  8. Governing Law. This Agreement shall be construed and
enforced in accordance with the internal laws of the Commonwealth of
Pennsylvania, without regard to conflicts of law principles.

                  9. 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 state or federal courts located in Philadelphia County,
Pennsylvania. Cornwell hereby consents to the jurisdiction of such courts and
waives any right to transfer or change the venue of any litigation brought
against Cornwell by MDMI or UTI.

                  10. Assignment. Cornwell may not assign this Agreement. The
rights of MDMI and UTI under this Agreement may be assigned to any third party
who succeeds to either MDMI's or UTI's business, as applicable.

                  11. Successors and Assigns. This Agreement shall be binding
upon and inure to the benefit of the parties hereto and their respective heirs
and personal representatives and, to the extent permitted by Section 10, their
respective successors and assigns.

                  12. Counterparts. This Agreement may be executed in two or
more counterparts, each of which shall be deemed an original, but all of such
counterparts shall together constitute a single agreement.

                  13. Headings. Section headings contained in this Agreement are
inserted for convenience of reference only, shall not be deemed to be a part of
this Agreement for any purpose, and shall not in any way define or affect the
meaning, construction or scope of any of the provisions hereof.

                  14. At-Will Employment. This Agreement shall not alter
Cornwell's status as an at-will employee, or the right of Cornwell, MDMI, UTI or
their affiliates, as applicable, to terminate the employment relationship with
or without cause, prior notice or other formality.

Affiliate of either Buyer or Star Guide that E. Pollock has acquired or become
acquainted with prior to the date of this Agreement, whether developed by E.
Pollock or by others, concerning any trade secrets, confidential or secret
designs, processes, formulae, plans, devices or material (whether or not
patented or patentable) directly or indirectly useful in any aspect of the
business of Buyer, Star Guide or any Affiliate of either Buyer or Star Guide,
any customer or supplier lists of Buyer, Star Guide or any Affiliate of either
Buyer or Star Guide, any confidential or secret development or research work of
Buyer, Star Guide or any Affiliate of either Buyer or Star Guide, or any other
confidential information or secret aspects of the business of Buyer, Star Guide
or any Affiliate of either Buyer or Star Guide. E. Pollock acknowledges that the
above-described knowledge or information constitutes a unique and valuable asset
of Buyer and/or Star Guide, and represents a substantial investment of time and
expense by Buyer and/or Star Guide, and that any disclosure or other use of such
knowledge or information other than for the sole benefit of Buyer and/or Star
Guide would be wrongful and would cause irreparable harm to Buyer and/or Star
Guide. During such 5-year period following the date of this Agreement, E.
Pollock agrees to refrain from any acts or omissions that would reduce the value
of such knowledge or information to Buyer, Star Guide or any Affiliate of either
Buyer or Star Guide. The foregoing obligations of confidentiality shall not
apply to any knowledge or information that is now published or which
subsequently becomes generally publicly known in the form in which it was
obtained from Buyer, Star Guide or any Affiliate of either Buyer or Star Guide,
other than as a direct or indirect result of the breach of this Agreement by E.
Pollock.

                  4. Severability Provision. To the extent that any provision
of this Agreement shall be determined to be invalid or unenforceable, such
provision shall be deleted from this Agreement, and the validity and
enforceability of the remainder of this Agreement shall be unaffected. In
furtherance of and not in limitation of the foregoing, it is expressly agreed
that, should the duration or geographical extent of, or business activities
covered by, this Agreement be finally determined to be in excess of that which
is valid or enforceable under applicable law, such provision shall be construed
to cover the maximum duration, extent or activities which may be validly or
enforceably covered. E. Pollock acknowledges the uncertainty of the law in this
respect and expressly stipulates that this Agreement shall be construed in a
manner which renders its provisions valid and enforceable to the maximum extent
(not exceeding its express terms) possible under applicable law.

                  5. Remedies. E. Pollock acknowledges that it would be
difficult to fully compensate Buyer and Star Guide for damages resulting from
any breach by such party of the provisions of this Agreement. Accordingly, in
the event of any actual or threatened breach of such provisions, Buyer and Star
Guide shall (in addition to any other remedies which it may have) be entitled to
temporary and/or permanent injunctive relief to enforce such provisions, and
such relief may be granted without the necessity of proving actual damages. E.
Pollock further acknowledges that this Agreement constitutes a material
inducement to Buyer to complete the Purchase and that Buyer will be relying on
the enforceability of this Agreement in completing the Purchase.

                  6. Remedies Cumulative. No remedy conferred by any of the
specific provisions of this Agreement is intended to be exclusive of any other
remedy, and each and every remedy shall be cumulative and shall be in addition
to every other remedy given hereunder or now or hereafter existing at law or in
equity or by statute or otherwise. The election of any one or more remedies by
any party hereto shall not constitute a waiver of the right to pursue other
available remedies.

                  7. Complete Agreement. This Agreement constitutes the entire
agreement, and supersedes all other prior and contemporaneous agreements and
undertakings, both written and oral, among the parties hereto relating to the
subject matter hereof. There are no representations, warranties, covenants,
statements, conditions, terms or obligations, other than those contained herein,
relating to the subject matter hereof. No amendments or modifications to or
variations of this Agreement shall be deemed valid unless in writing and
executed by Buyer, Star Guide and E. Pollock.

                  8. Governing Law. This Agreement shall be construed and
enforced in accordance with the internal laws of the State of Colorado, without
regard to conflicts of law principles.

                  9. 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 state or federal courts located in Denver County,
Colorado. E. Pollock hereby consents to the jurisdiction of such courts and
waives any right to transfer or change the venue of any litigation brought
against E. Pollock by Buyer or Star Guide.

                  10. Assignment. E. Pollock may not assign this Agreement. The
rights of Buyer and Star Guide under this Agreement may be assigned to any third
party who succeeds to either Buyer's or Star Guide's business, as applicable.

                  11. Successors and Assigns. This Agreement shall be binding
upon and inure to the benefit of the parties hereto and their respective heirs
and personal representatives and, to the extent permitted by Section ------- 10,
their respective successors and assigns.

                  12. Counterparts. This Agreement may be executed in two or
more counterparts, each of which shall be deemed an original, but all of such
counterparts shall together constitute a single agreement.

                  13. Headings. Section headings contained in this Agreement are
inserted for convenience of reference only, shall not be deemed to be a part of
this Agreement for any purpose, and shall not in any way define or affect the
meaning, construction or scope of any of the provisions hereof.
