                             SUBSCRIPTION AGREEMENT

                  THIS SUBSCRIPTION AGREEMENT (this "Agreement") is made as of
[SEE ITEM 1 ANNEX A] by and between MDMI Holdings, Inc., a Colorado corporation
(the "Company") and [SEE ITEM 2 ANNEX A] ("Holder").

                                    RECITALS

                  WHEREAS, UTI Acquisition Corp., a Colorado corporation and

Company will acquire all of the outstanding capital stock of UTI (the

                  WHEREAS, Holder is one of the shareholders of UTI; and

                  WHEREAS, the Company wishes to issue, and Holder wishes to
acquire [SEE ITEM 3 ANNEX A] (collectively, the "Shares") in exchange for the
contribution to the capital of the Company of [SEE ITEM 4 ANNEX A] (the
"Purchase Price").

                                    AGREEMENT

                  NOW, THEREFORE, in consideration of the mutual promises and
covenants contained herein, the parties hereto do hereby agree as follows:

                  1. SUBSCRIPTION. The subscription by Holder will occur as of
May 31, 2000 (the "Closing"). At the Closing, the Company will issue to Holder
and subject to the terms and conditions set forth herein, Holder will acquire
from the Company, the Shares in exchange for the Purchase Price.

                  2. REPRESENTATIONS OF HOLDER. In connection with the
acquisition of the Shares hereunder, Holder represents and warrants to the
Company that the statements contained in this paragraph 2 are true, accurate,
correct and complete in all material respects.

                           (a) The Shares to be acquired by Holder pursuant to
this Agreement will be acquired for Holder's own account and not with a view to,
or intention of, distribution thereof in violation of the Securities Act of
1933, as amended (the "Securities Act"), or any applicable state securities
laws, and none of the Shares will be disposed of in contravention of the
Securities Act or any applicable state securities laws.

                           (b) Holder is an accredited investor, as such term is

familiar with, and has been afforded full access to and has had an opportunity
to ask questions and receive answers concerning the terms and conditions of the
offering of Shares and such other information concerning the Company that Holder
has requested and is required in Holder's judgment to make an informed decision
to acquire the Shares.

                           (c) Holder is able to bear the economic risk of
Holder's investment in the Shares for an indefinite period of time because the
Shares have not been registered under the Securities Act and, therefore, cannot
be sold unless subsequently registered under the Securities Act and any
applicable state securities acts or an exemption from such registration is
available.

                           (d) Holder will not sell, assign or otherwise
transfer the Shares subscribed for herein unless such sale, assignment or other
transfer is made in compliance with the terms of that Shareholders' Agreement
dated July 6, 1999, among the Company, Holder and certain other individuals (the
"Shareholders' Agreement").

                           (e) Holder has full corporate or individual power, as
applicable, and authority to execute and deliver this Agreement and to perform
its, his or her obligations hereunder. This Agreement constitutes the legal,
valid and binding obligation of Holder, enforceable in accordance with its
terms, and the execution, delivery and performance of this Agreement and such
other agreements by Holder does not and will not (A) conflict with or result in
any breach of any provision of the certificate of incorporation or bylaws or
similar organizational documents of Holder, as applicable (B) violate any
constitution, statute, regulation, rule, injunction, judgment, order, decree,
ruling, charge, or other restriction of any Governmental Agency (as defined
below) to which Holder is subject or (C) conflict with, violate or constitute a
breach or default (or an event that, with notice or lapse of time, or both,
would constitute a default) under, or of any agreement, contract or instrument
to which Holder is a party or result in the acceleration of, create in any party
the right to accelerate, terminate, modify, or cancel, or require any notice
under any agreement, contract, lease, license, instrument, note, bond, mortgage,
deed of trust, or other arrangement to which Holder is a party or by which he is
bound or to which any of its, his or her assets is subject and Holder further
represents and warrants that Holder is not now in breach of any such agreement,
contract or instrument to which Holder is a party. Holder need not give any
notice to, make any filing with, or obtain any authorization, consent or
approval of any Governmental Authority in order to consummate the transactions
contemplated hereby.

                           (f) Holder has no liability or obligation to pay any
fees or commissions to any broker, finder or agent with respect to the
transactions contemplated hereby for which the Company could become liable or
obligated.

                           (g) There are no bankruptcy, reorganization or
arrangement proceedings pending against, being contemplated by, or, to the
knowledge of Holder, threatened against him.

                  3. REPRESENTATIONS OF THE COMPANY. In connection with the

                                    (i) All securities transferred pursuant to
this Agreement are Restricted Securities (as defined below in subparagraph
4(a)(iii) below) that are transferable pursuant to (A) public offerings
registered under the Securities Act, (B) Rule 144 of the Securities and Exchange
Commission (or any similar rule then in force) if such rule is available and (C)
subject to the conditions specified in subparagraph 4(a)(ii) below, any other
legally available means of transfer.

                                    (ii) In connection with the transfer of any
Restricted Securities (other than a transfer described in subparagraph 4(i)(A)
or (B) above), the holder thereof will deliver written notice to the Company
describing the transfer or proposed transfer, and, if requested by the Company,
will also deliver an opinion (reasonably satisfactory to the Company) of counsel
that (to the Company's reasonable satisfaction) is knowledgeable in securities
law matters to the effect that such Restricted Securities may be transferred
without registration of such Restricted Securities under the Securities Act.

                                    (iii) For the purposes of this Agreement,
"Restricted Securities" means the Shares, and any securities issued with respect
thereto by way of a stock dividend or stock split or in connection with a
combination of shares, recapitalization, merger, consolidation or other
reorganization. As to any particular Restricted Securities, such securities will
cease to be Restricted Securities when they have (A) been effectively registered
under the Securities Act and disposed of in accordance with the registration
statement covering them or (B) become eligible for sale and have actually been
sold to the public pursuant to Rule 144 (or any similar provision then in force)
under the Securities Act. Whenever any particular securities cease to be
Restricted Securities, the holder thereof will be entitled to receive from the
Company, without expense, new certificates therefor not bearing a Securities Act
legend of the character set forth in paragraph 5(a).

                  5. MISCELLANEOUS.

                  NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
                  AMENDED. THE TRANSFER, ENCUMBRANCE, PLEDGE, ASSIGNMENT OR

                  AND THE COMPANY RESERVES THE RIGHT TO REFUSE THE TRANSFER OF
                  SUCH SECURITIES UNTIL SUCH CONDITIONS AND RESTRICTIONS HAVE
                  BEEN FULFILLED OR LIFTED WITH RESPECT TO SUCH TRANSFER. A COPY
                  OF THE CONDITIONS OR AGREEMENTS REFERENCED ABOVE MAY BE
                  OBTAINED BY THE HOLDER HEREOF UPON WRITTEN REQUEST TO THE
                  SECRETARY OF THE COMPANY."

Each of the undersigned parties agrees that the Company may instruct its
transfer agent to impose transfer restrictions on the Shares represented by
certificates bearing the legend referred to in this paragraph 5(a) to enforce
the provisions of this Agreement. The legend shall be removed or modified upon
termination of the conditions or restrictions set forth therein or pursuant to
subparagraph 4(a)(iii).

                  (b) SUCCESSORS AND ASSIGNS. Except as otherwise expressly
provided herein or in any instruments of transfer or assignment, all covenants
and agreements contained in this Agreement by or on behalf of any of the parties
hereto will bind and inure to the benefit of the respective successors and
assigns of the parties hereto whether so expressed or not. In addition, and
