                           b. Execution and Delivery Authorized. The execution
and delivery of this Agreement and the consummation of the transactions
contemplated by this Agreement have been duly authorized by the board of
directors of PPD and by PPD as the sole shareholder of Intek. No approval of the

                           c. Validity of Agreement. Except for customer
contracts of Intek which contain provisions requiring consent to change of
control, the execution and performance of this Agreement and the actions
provided for or contemplated hereunder will not violate the provisions of any
agreement, instrument or obligation to which either PPD or Intek is a party.
Assuming due authorization, execution and delivery hereof by the Corporation,
this Agreement constitutes the valid and binding agreement of PPD, enforceable
against PPD in accordance with its terms, subject as to enforceability to
general equitable principles and to the laws of bankruptcy, insolvency or
similar laws governing the rights of creditors.

                           d. Title to Intek Shares. The Intek Shares are now
and shall be, upon the Transfer, free and clear from any liens, claims,
restrictions or encumbrances of any kind or nature whatsoever, except for such
restrictions contained in the Articles of Incorporation or the Bylaws of Intek,
as now in existence or restrictions upon transfer arising under federal or state
securities laws. Neither PPD nor Intek is a party to or bound by any agreement,
instrument, trust, proxy or understanding restricting or otherwise binding the
ownership, transfer or voting of any of the Intek Shares. Upon completion of the
Transfer, the Intek Shares shall be validly issued and will be fully paid and
nonassessable.

shares of Intek have been duly authorized and validly issued, are fully paid and
are nonassessable. None of the outstanding shares of Intek were issued in
violation of the preemptive rights of any shareholder and none will be subject
to any preemptive or similar rights. There are no outstanding subscriptions,
options, warrants, contracts or any other commitments or rights (including
rights to distributions or payments) of any character with respect to, or

of any extension of time within which to file any Tax Return. No claim has ever
been made by an authority in a jurisdiction where Intek does not file Tax

no security interests on any of the assets of Intek that arose in connection
with any failure (or alleged failure) to pay any Tax.

responsible for Tax matters) of Intek has Knowledge based upon personal contact

                  4. Representations, Warranties and Covenants of the
Corporation. The Corporation represents and warrants to PPD and covenants with
PPD that as of the Transfer Date:

                           a. Organization and Standing of the Corporation. The
Corporation is duly organized and validly existing and has complied with all
requirements to continue its existence under the laws of the State of Delaware,
and has the corporate power and authority to own, lease and use its properties
and to transact its business where and as now conducted.

                           b. Execution and Delivery Authorized. The execution

contemplated by this Agreement have been duly authorized by the board of
directors of the Corporation.

                           c. Validity of Agreement. The execution and
performance of this Agreement and the actions provided for or contemplated
hereunder will not violate the provisions of any agreement, instrument or
obligation to which the Corporation is a party or by which it is bound. Assuming
due authorization, execution and delivery hereof by PPD, this Agreement
constitutes the valid and binding agreement of the Corporation, enforceable
against the Corporation in accordance with its terms, subject as to
enforceability to general equitable principles and to the laws of bankruptcy,
insolvency or similar laws governing the rights of creditors.

                                       11

                           d. Access and Information. The Corporation and its
representatives have been afforded full and free access to Intek's financial
statements and other information concerning Intek and the Corporation has been
afforded an opportunity to ask such questions of Intek's officers, employees,
agents, accountants and representatives concerning Intek's business, prospects,
operations, financial condition, assets, liabilities and other relevant matters,
including the rights, preferences and limitations of the Intek Shares, as the
Corporation deems necessary or desirable and has been given all such information
as has been requested, in order to evaluate the merits and risks associated with
holding the Intek Shares. The Corporation has conducted its own "due diligence"
investigation of Intek and its management and business, and its own analysis of
the merits and risks of holding the Intek Shares, and its own analysis of the
fairness and desirability of the terms governing the transfer of the Intek
Shares. The Corporation is familiar with the business conducted by Intek on and
has such knowledge and experience in financial and business matters that the
Corporation is capable of evaluating the merits and risks of the transfer of the
Intek Shares pursuant to the terms of this Agreement and of protecting the
Corporation's interests in connection therewith.

                           e. Investment Intent of the Corporation. The Intek
Shares are being acquired by the Corporation for its own account and not with a
view to, or for resale in connection with, any distribution or public offering
thereof within the meaning of the Securities Act of 1933, as amended (the
"Securities Act"). The Corporation understands that the Intek Shares have not
been, and will not be, registered under the Securities Act by reason of their
issuance in a transaction exempt from the registration requirements of the
Securities Act, that Intek has no present intention of registering the Intek
Shares, that the Intek Shares must be held by the Corporation indefinitely, and
that the Corporation must therefore bear the economic risk associated with
holding the Intek Shares indefinitely, unless a subsequent disposition thereof
is exempt from registration. The Corporation is able to bear the economic risk
of holding the Intek Shares pursuant to the terms of this Agreement. Each
certificate evidencing the Intek Shares shall be endorsed with the following
legend:

                  THE SHARES OF STOCK EVIDENCED BY THIS CERTIFICATE HAVE NOT
                  BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED
                  (THE "SECURITIES ACT"), OR ANY APPLICABLE STATE SECURITIES
                  LAWS, AND MAY NOT BE SOLD, OFFERED FOR SALE, ASSIGNED,
                  MORTGAGED, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED
                  WITHOUT AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
                  SECURITIES ACT COVERING SUCH SHARES, AND APPLICABLE STATE
                  SECURITIES LAW, OR AN OPINION OF COUNSEL REASONABLY
                  SATISFACTORY TO THE CORPORATION THAT THE TRANSACTION DOES NOT
                  VIOLATE FEDERAL OR STATE SECURITIES LAWS.

The Corporation acknowledges that no public market now exists for the Intek
Shares and that there can be no assurance that any public market will exist in
the future. The Corporation understands


                                       12
<PAGE>

that the Intek Shares will constitute "restricted securities", and under the
Securities Act and applicable regulations the Intek Shares may be resold without
registration under the Securities Act only in certain limited circumstances. In
this connection, the Corporation represents that it is familiar with Rule 144
under the Securities Act and understands the resale limitations imposed thereby
and the Securities Act.

                           f. Accredited Investor Status. The Corporation
represents and warrants that it is an "accredited investor" as defined in Rule
501 of Regulation D of the Securities Act.

                  5. Indemnification. Notwithstanding anything in this Agreement
to the contrary and subject to a time limit of eighteen (18) months following
the Transfer Date, PPD shall indemnify, defend, and hold harmless the
Corporation, its affiliates, successors and assigns from and against all General
Losses of the Corporation. Notwithstanding anything in this Agreement to the
contrary and subject to a time limit of eighteen (18) months following the
Transfer Date, the Corporation shall indemnify, defend, and hold harmless PPD,
its affiliates, successors and assigns from and against all General Losses of
PPD.

                  6. Governing Law. This Agreement shall be governed by and
shall be construed in accordance with the laws of the State of Delaware.

                  7. Entire Agreement. This Agreement contains the entire
understanding between the parties and supersedes any prior understandings or
agreements between them affecting the subject matter. No changes, alterations,
amendments, modifications, additions or qualifications to the terms of this
Agreement shall be made or be binding unless made in writing and signed by each
of the parties.

                  8. Notices. All notices and other communications hereunder
shall be in writing and shall be deemed given if delivered personally or by
commercial delivery service, or mailed by certified mail (return receipt
requested) or sent via facsimile (with confirmation of receipt) to the parties
at their respective addresses first set forth above (or at such other address
for a party as shall be specified by like notice.

                  9. Binding Effect. This Agreement shall be binding upon, and
inure to the benefit of, the parties, their heirs, legal representatives,
successors and permitted assigns.

                  10. Counterparts. This Agreement may be executed in one or
more counterparts, all of which shall be considered one and the same agreement.

                  11. Entire Agreement. This Agreement, together with the
recitals, exhibits and schedules, contains the entire understanding of the
parties hereto with respect to the transactions contemplated herein, and any
prior agreements or understandings, whether oral or written, are entirely
superseded hereby.

                  12. Documentation. The parties agree to execute and/or provide
any and all other documents, instruments, or other papers and to conduct such
transactions as may be reasonably necessary or desirable to effectuate the
provisions of this Agreement.

                  13. Survival of Representations, Warranties, Covenants.
Notwithstanding any investigation by either party or any knowledge of facts
uncovered pursuant to any such investigation, each party shall have the right to
rely fully upon the representations, warranties, covenants, conditions and
agreements of the other party contained in this Agreement. All such
representations, warranties, covenants, conditions and agreements contained in
this Agreement shall survive the Transfer for a period of eighteen (18) months
from the Transfer Date.

         IN WITNESS WHEREOF, the Corporation and PPD have caused this Agreement
to be executed and delivered by their respective officers, duly authorized, all
as of the date first written above.
