consummate the transactions contemplated herein, PGTC represents and warrants
to LLC as follows:

which the Certificate of Dissolution with the Secretary of State of Delaware
is filed to dissolve PGTC (as set forth in the Recitals to the Operating
Agreement), PGTC is a corporation duly organized and validly existing and in
good standing under the laws of the state of Delaware, and has all corporate
power and authority required to carry on the PGTC Business as now conducted

bankruptcy, insolvency, reorganization, moratorium or similar laws affecting
creditors' rights generally and subject to general principles of equity.

                  5.03.    NON-CONTRAVENTION. Assuming the Required Consents
are obtained, to the knowledge of PGTC, the execution, delivery and
performance by PGTC of this Agreement and the Ancillary Documents does not
and will not materially conflict with, constitute a material default under or
be prevented by the terms of any Contract.

                  5.04.    FINANCIAL STATEMENTS. The unaudited balance sheet
of PGTC as of December 31, 1998, the unaudited income statement for the year

1999 (the "Balance Sheet") and the unaudited income statement for the
four-month period ended April 30, 1999, a copy of each of which has been
delivered to LLC, present fairly the financial position and assets and
liabilities of PGTC in all material respects as of such date.


                                       7

                  5.05.    PROPERTIES; LEASES. PGTC holds title to all of
the Transferred Assets owned by it and WLFC has a valid leasehold interest in
all of the Facilities.

                  5.06.    LITIGATION. Except as set forth on SCHEDULE 5.06,
there are no (a) actions, suits, hearings, arbitrations, proceedings (public
or private) or investigations that have been brought by or against any
Governmental Authority or any other Person (collectively, "Proceedings")
pending or, to the knowledge of PGTC, any threatened material Proceedings,
against or affecting the PGTC Business or any of the Transferred Assets or
which seek to enjoin or rescind the transactions contemplated by this
Agreement or otherwise prevent PGTC from complying with the terms and
provisions of this Agreement or (b) existing orders, judgments or decrees of
any Governmental Authority affecting any of the Transferred Assets or the
PGTC Business.

                  5.07.    BROKERS. PGTC is not a party to any contract,
agreement, arrangement or understanding with any Person which will result in
the obligation of LLC to pay any finder's fee, brokerage commission or
similar payment in connection with the transactions contemplated hereby.

                                   ARTICLE VI.

                      REPRESENTATIONS AND WARRANTIES OF LLC

to consummate the transactions contemplated herein, LLC hereby represents and

consummation by LLC of the transactions contemplated hereby and thereby are
within the powers of LLC and have been duly authorized by all necessary
action on the part of LLC. This Agreement and the Ancillary Documents
constitute a legal, valid and binding agreement of LLC, enforceable in

                              CONDITIONS TO CLOSING

                                       9

                        (a)  Notwithstanding Sections 9.02 and 9.03 hereto,
the rights and obligations under this Article IX of the PGTC Indemnitees and
LLC are subject to the following:

                             (i)   neither the PGTC Indemnitees nor
                  LLC shall be entitled to any recovery unless a claim for
                  indemnification is made in accordance with Section 9.05(a),
                  the claim for indemnification is made within the time period
                  of survival set forth in Section 9.01 and the entity seeking
                  indemnification complies with the procedures set forth in
                  Section 9.05;

                             (ii)  the PGTC Indemnitees, on the one
                  hand, and LLC, on the other hand, shall not be entitled to any
                  indemnification hereunder unless and until the Losses that the
                  relevant party is entitled to be indemnified for hereunder
                  exceed, in the aggregate, $250,000, in which event the
                  relevant party shall only be entitled to recover Losses that
                  are in excess of $250,000; PROVIDED, HOWEVER, that any Losses
                  with respect to the items set forth on SCHEDULE 5.06 shall not
                  be subject to the limitations of this Section 9.04(a)(ii); and

                             (iii) neither the PGTC Indemnitees nor
                  LLC shall be entitled to recover Losses from the other
                  totaling in excess of the sum of $__________* PLUS the amount
                  of the additional cash capital contribution made by CGTC to

                                       10



                        (b)  The indemnification provisions in this Article IX
shall be the exclusive remedy for any breach of the representations and
warranties set forth in this Agreement.

                  9.05. PROCEDURE FOR INDEMNIFICATION. The procedure for
indemnification shall be as follows:

                        (a)  The party claiming indemnification (the
"Claimant") shall promptly give written notice to the party from whom
indemnification is claimed (the "Indemnifying Party") of any claim, whether
between the parties or brought by a third party, specifying (i) in reasonable
detail, the factual basis for such and (ii) in good faith, the estimated
amount of the claim. If the claim relates to an action, suit or proceeding
filed by a third party against the Claimant, such notice shall be given by
Claimant within ten business days after written notice of such action, suit
or proceeding was received by Claimant. The failure of the Claimant to
provide such written notice within the time period specified shall not
relieve the Indemnifying Party of its indemnification liability under
Section 9.02 or Section 9.03, unless such failure materially prejudices the
rights of the Indemnifying Party in defending against the claim or action.

                        (b)  Following receipt of notice from the Claimant of
a claim, the Indemnifying Party shall have 30 days to make such investigation
of the claim as the Indemnifying Party deems necessary or desirable. For the
purposes of such investigation, the Claimant agrees to make available to the
Indemnifying Party and/or its authorized representative(s) the information
relied upon by the Claimant to substantiate the claim. If the Claimant and
the Indemnifying Party agree at or prior to the expiration of said 30-day
period (or any mutually agreed upon extension thereof) to the validity and
amount of such claim, the Indemnifying Party shall immediately pay to the
Claimant the full amount of the claim. If the Claimant and the Indemnifying
Party do not agree within said period (or any mutually agreed upon extension
thereof), subject to clause (c) below with respect to third party claims, the
Claimant may seek appropriate legal remedy.

                        (c)  With respect to any claim by a third party as to
which the Claimant is entitled to indemnification hereunder, the Indemnifying
Party shall have the right, at its own expense, to participate in or assume
control of the defense of such claim, and the Claimant shall cooperate fully
with the Indemnifying Party. If the Indemnifying Party elects to assume
control of the defense of any third-party claim, the Claimant shall have the
right to participate in the defense of such claim with legal counsel of its
own selection; PROVIDED, HOWEVER, that the Claimant shall pay the fees and
expenses of such counsel. If the Indemnifying Party does not elect to assume
control or otherwise participate in the defense of any third party claim, it
shall be bound by the results obtained by the Claimant with respect to such
Claim; PROVIDED, HOWEVER, that no settlement or compromise of any claim which
may result in any indemnification liability may be made by the Claimant
without the prior written consent of the Indemnifying Party.


                                       11



                        (d)  If a claim, whether between the parties or by a
third party, requires immediate action, the parties will make every effort to
reach a decision with respect thereto as expeditiously as possible.

                        (e)  Upon satisfaction of any third party claim
pursuant to this Article IX, the Indemnifying Party shall be subrogated to
all rights and remedies of the Claimant against any third party with respect
to such claim.

                                  ARTICLE X.

                  10.12. DISPUTE RESOLUTION.

                         (a)  Any controversy or claim arising out of or
relating to this Agreement (or breach thereof), whether arising in tort,
contract or otherwise, shall be settled in accordance with the following
procedures:

                              (i)   The parties shall first attempt to
                  resolve such controversy or claim by meeting with an
                  independent mediator chosen by both parties.

                              (ii)  If the parties are unable to
                  mutually agree upon a mediator, then the mediator shall be
                  appointed by the American Arbitration Association in the
                  San Diego, California metropolitan area ("AAA") in accordance
                  with then-current commercial rules of mediation thereof.

                              (iii) If such controversy or claim cannot
                  be resolved by mediation within sixty (60) days after the
                  party raising the controversy or claim first notifies the
                  other party thereof in writing, then the controversy or claim
                  shall be submitted to AAA for binding arbitration, to be held
                  in San Diego, California metropolitan area in accordance with
                  the then-current commercial rules of arbitration of AAA.

                         (b)  The award from any binding arbitration shall be
binding upon the parties and their successors and permitted assigns, whether
or not any party fails or refuses to participate therein, and judgment upon
the award rendered by the arbitrator may be entered in any court having
jurisdiction thereof.

                         (c)  The arbitrator shall have the power to issue
injunctions and otherwise to grant equitable relief, and shall award legal
fees and costs (including fees and costs incurred by AAA and by the
arbitrator) to the prevailing party. The arbitrator shall not have the power
to award punitive, exemplary or indirect damages.

                         (d)  Except as otherwise provided in Article IX and
as may be otherwise ordered by the arbitrator in accordance with
Section 10.12(c), each party shall bear its own costs and expenses in
connection with any proceeding commenced under this Section 10.12, including,
without limitation, legal fees and disbursements, travel expenses, witness
fees and costs, photocopying and other preparation expenses. The costs and
other fees charged by the independent mediator or AAA, whether in connection
with a mediation and/or arbitration, shall be shared generally by the parties.
