Item 5.  Other Events
- -------  ------------

                 On December 6, 1996, the Company entered into an Agreement and
Plan of Merger with  Titan Enterprises, Inc., a Delaware corporation ("Titan"),
and Panatech Acquisition Corporation, a Nevada corporation and wholly owned
subsidiary of Titan ("Merger Sub") (the "Merger Agreement"), pursuant to which,
and subject to satisfaction of the conditions set forth therein, (i) Merger Sub
will be merged with and into the Company (the "Merger"), with the Company
continuing as the surviving corporation, (ii) the Company will become a wholly
owned subsidiary of the Titan, and (iii) each outstanding share of the
Company's common stock (other than shares owned by Titan, Merger Sub or
subsidiaries of the Company, if any, which shares will be canceled) will be
converted, upon the effectiveness of the Merger, into the right to receive
$7.00 in cash per share, without interest, subject to reduction.  The Merger
Agreement also provides for payment to the holders of the Company's Class B
Warrants of an amount equal to the consideration payable per share of common
stock less the exercise price per share of the Class B Warrants.  Consummation
of the Merger is subject to, among other things, approval of the Merger
Agreement by the Company's shareholders and regulatory approvals.  If the
Merger Agreement is terminated under certain circumstances relating to an
acquisition of the Company by a third party, the Company has agreed to pay
Titan a fee equal to $994,844.

         A copy of the Merger Agreement is attached hereto as Exhibit 2.1 and
is incorporated herein by reference.

termination or other event had not occurred, regardless of whether or not the

Representative pursuant to Section 12.3 shall constitute effective notice to the
Stockholders, and any other party to this Agreement or any other Person may rely

                              MERGER CONSIDERATION

               Section 3.1 Merger Consideration.

               (a)Subject to adjustment pursuant to Section 3.1(b), the
aggregate merger consideration shall be $7.00 in cash per share of Stock as set
forth in Section 2.6(a) plus amounts payable in cash upon the cancellation of
Panatech Stock Options and Panatech Warrants pursuant to Section 2.7(a) (the
"Merger Consideration").

               (b)The Merger Consideration is subject to adjustment in the
following manner:

                  (i) Parent and Panatech shall attempt to jointly determine the
Quick Assets and Target Number on the Closing Date.


                                      A-9
<PAGE>   16
                           (ii) If Parent and Panatech cannot agree on the Quick
Assets and Target Number on the Closing Date, then as soon after the Closing
Date as possible, the Stockholders' Representative shall cause to be prepared in
accordance with the Principles and Procedures a statement of Quick Assets (the
"Quick Assets Statement") and shall cause such Quick Assets Statement to be
examined by the Accountants in accordance with the Principles and Procedures. As
soon as possible upon the conclusion of such examination, but in no event later
than five (5) business days after the Closing Date, the Accountants shall issue
a report to Parent and the Stockholders' Representative setting forth the
results of its examination and its determination of the Quick Assets and Target
Number (the "Closing Report"). Price Waterhouse shall have the opportunity to
review and evaluate all working papers, worksheets and other documents utilized
by the Stockholders' Representative in the preparation of the Quick Assets
Statement and by the Accountants in the preparation of the Closing Report. If
Parent agrees with the calculation of Quick Assets and Target Number pursuant to
the Quick Assets Statement and Closing Report, Parent shall notify the
Stockholders' Representative in writing as soon as possible following receipt of
the Quick Assets Statement and Closing Report.

                           (iii) If the Quick Assets of Panatech on the Closing
Date, as determined in accordance with the Quick Assets Statement and the
Closing Report, are less than the Target Number, and if such difference is not
disputed pursuant to this Section 3.1(b), the Merger Consideration shall be
decreased by the amount by which the Target Number exceeds the Quick Assets, and
the consideration to be paid per share of stock as set forth in Section 2.6(a)
and per cancelled Panatech Stock Option and Panatech Warrant pursuant to Section
2.7(a) shall be reduced pro-rata (a sample calculation of which is set forth on
Exhibit E). If the Quick Assets, as determined in accordance with the Quick
Assets Statement and the Closing Report, is equal to or greater than the Target
Number, the Merger Consideration shall not be adjusted.

                           (iv) If Parent disputes any items shown on the Quick
Assets Statement or Closing Report, Parent will provide the Stockholders'
Representative within five (5) days of receipt of the Quick Assets Statement and
Closing Report detailed written explanations of any disputed items in the Quick
Assets Statement or Closing Report. The amount of the Quick Assets and Target
Number not affected by the disputed items will be deemed to be as set forth in
the Quick Assets Statement and Closing Report. Within a further period of ten
(10) days from the end of the aforementioned review period, the parties will
attempt to resolve in good faith any disputed items.

                           (v) Failing resolution pursuant to paragraph (iii)
above, the unresolved disputed items will be referred for final binding
resolution to a nationally-recognized firm of certified public accountants as
the parties may hereafter jointly select (the "Arbitrator"). Such referral shall
be in the form of written statements of position by the Stockholders'
Representative, Parent, Price Waterhouse and the Accountants, with each party
having an opportunity to respond to such written statements and any requests for
statements or information by the Arbitrator. If the Arbitrator


                                      A-10
<PAGE>   17
determines that the resolution of a given disputed item requires an
interpretation of law, then, with the permission of the parties, the Arbitrator
may request a law firm of national standing chosen by it to render a legal
opinion as to such matter. The amount of the Quick Assets and/or Target Number
affected by such unresolved disputed items (if any) will be as determined by the
Arbitrator. The cost of such Arbitrator's review (including reasonable
attorneys' fees, if any) shall be borne by the party or parties as determined by
the Arbitrator.


                           Section 3.2. Payment of Merger Consideration.

                           (a)(i) Exchange Agent. Immediately after the
Effective Time and after determination of the Merger Consideration pursuant to
Section 3.1, Parent shall deposit with U.S. Stock Transfer Corporation (the
"Exchange Agent"), a cash amount equal to the aggregate Merger Consideration to
which holders of shares of Stock and Panatech Warrants shall be entitled upon
consummation of the Merger, to be held for the benefit of and distributed to
such holders in accordance with this Section 3.2. The Exchange Agent shall agree
to hold such funds (such funds, together with earnings thereon, being referred
to herein as the "Exchange Fund") for delivery as contemplated by this Section
3.2 and upon such additional terms as may be agreed upon by the Exchange Agent,
Panatech and Parent before the Payment Date.

                              (ii) Panatech Stock Options. Immediately after the
Effective Time and after determination of the Merger Consideration pursuant to
Section 3.1, Parent shall pay each holder of Panatech Stock Options cancelled
pursuant to Section 2.7, by check or wire transfer, the Merger Consideration per
Panatech Stock Option which such holder has the right to receive pursuant to
Section 2.7. In no event will any such holder be entitled to interest on any
funds to be received in the Merger

                           (b) Exchange Procedures. Promptly after the Effective
Time, the Surviving Corporation shall cause the Exchange Agent to mail to each
holder of record of a certificate or certificates which immediately prior to the
Effective Time represented outstanding shares of Stock and Panatech Warrants
(collectively, the "Certificates") whose shares or warrants are converted
pursuant to Sections 2.6 or 2.7, as the case may be, into the right to receive
the Merger Consideration (i) a letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the Certificates shall
pass, only upon delivery of the Certificates to the Exchange Agent and shall be
in such form and have such other provisions as the Surviving Corporation may
reasonably specify) and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for the Merger Consideration. Upon surrender of a
Certificate for cancellation to the Exchange Agent, together with such letter of
transmittal duly executed and completed in accordance with its terms, the holder
of such Certificate shall be entitled to receive in exchange therefor a check
representing the Merger Consideration per share of Stock or Panatech Warrant, as
the case may be, represented thereby which such holder has the right to receive
pursuant to the provision of this Article III, and the Certificate so
surrendered shall forthwith be canceled. In no event

                                      A-11
<PAGE>   18
shall the holder of any Certificate be entitled to receive interest on any funds
to be received in the Merger. In the event of a transfer of ownership of Stock
or Panatech Warrant which is not registered in the transfer records of Panatech,
the Merger Consideration may be issued to a transferee if the Certificate
representing such Stock or Panatech Warrant is presented to the Exchange Agent
accompanied by all documents required to evidence and effect such transfer and
by evidence that any applicable transfer taxes have been paid. Until surrendered
as contemplated by this Section 3.2, each Certificate shall be deemed at any
time after the Effective Time to represent only the right to receive upon such
surrender the Merger Consideration per share of Stock or Panatech Warrant, as
the case may be, represented thereby as contemplated by this Article III.
Holders of Panatech Warrants outstanding at or immediately prior to the
Effective Time shall, subject to Section 3.2(d), be entitled to receive the
appropriate Merger Consideration upon surrender of their Certificates
notwithstanding the fact that such Panatech Warrants are submitted for payment
following their expiration date.

                           (c) No Further Ownership Rights in Stock. All cash
paid upon the surrender of shares of Stock, Panatech Stock Options or Panatech
Warrants in accordance with the terms hereof shall be deemed to have been paid
in full satisfaction of all rights pertaining to such shares of Stock, Panatech
Stock Options or Panatech Warrants, as the case may be. If, after the Effective
Time, Certificates are presented to the Surviving Corporation for any reason,
they shall be canceled and exchanged as provided in this Section 3.2.

                           (d) Termination of Exchange Fund. Any portion of the
Exchange Fund which remains undistributed to the stockholders of Panatech or
holders of Panatech Warrants for one hundred twenty (120) days after the Payment
Date shall be delivered to the Surviving Corporation, upon demand, and any
stockholders of Panatech or holders of Panatech Warrants who have not
theretofore complied with this Section 3.2 shall thereafter look only to the
Surviving Corporation (subject to abandoned property, escheat and other similar
laws) as general creditors for payment of their claim for the Merger
Consideration. Neither Parent nor the Surviving Corporation shall be liable to
any holder of shares of Stock or holders of Panatech Warrants for cash
representing the Merger Consideration delivered to a public official pursuant to
any applicable abandoned property, escheat or similar law. If outstanding
Certificates are not surrendered, or cash payment therefor not claimed prior to
six years after the Payment Date (or, in any particular case, prior to such
earlier date on which such cash payment would otherwise escheat to or become the
property of any governmental unit or agency), the unclaimed amounts shall, to
the extent permitted by applicable law, become the property of the Surviving
Corporation, free and clear of all claims or interest of any person previously
entitled thereto.
