          (iii) At the effective time of the Closing, Premier shall issue the
     warrants constituting the Warrant Consideration (in the form attached

     any Lien or Restriction imposed pursuant to the terms of this Purchase
     Agreement or the Warrant Agreement) or the applicable federal or state
     securities laws, and

          (vi)  Each party shall take such other actions, and shall execute
     and deliver such other instruments or documents, as shall be required under

          2.4   Purchase Consideration Adjustment.  In order to insure that
                ---------------------------------                          
Seller receives the same per share Purchase Consideration as that to be paid
under the Tender Offer, Seller hereby agrees to allow Premier to retroactively
readjust the amount of Purchase Consideration previously paid or granted to
Seller if, at the Expiration Date (as that term is defined and used within the
Acquisition Agreement) the Cash Consideration, the Stock Consideration or the
Warrant Consideration that Seller would have received under the Tender Offer
differs from that initially paid or granted to Seller under this Purchase
Agreement.  If such Warrant Consideration amounts are disparate, Premier shall
either grant Seller the right to purchase additional shares of Premier Common
Stock (the "Additional Warrant Shares") or cancel Seller's existing
documentation evidencing the Warrant Consideration and reissue new documentation
evidencing the reduced number of shares Seller is eligible to purchase.
Similarly, if the Stock Consideration amounts are found to be disparate, Premier
shall either issue Seller additional shares of Premier Common Stock (the
"Additional Stock Payment Shares") or cancel Seller's existing shares and
reissue a certificate evidencing fewer shares to the effect that Seller shall
ultimately receive the same per share Stock Compensation as would have been
provided under the Tender Offer.  If the amounts of Cash Consideration are
disparate and in Seller's favor, Premier shall pay Seller the additional cash.
If such difference is in Premier's favor, Seller shall remit the difference in
cash to Premier.  The readjustment and exchange of Cash Consideration shall be
completed to the effect that Seller receives the same per share Cash
Consideration as he, she or it would have under the Tender Offer.

               -----------------------------------------                     
and warrants to the Seller as of the date hereof and as of the Closing Date as
follows:

          (a)  Organization, Standing and Corporate Power.  Premier is duly
               ------------------------------------------                  
organized, validly existing and in good standing under the laws of the State of
California and has the requisite corporate power and authority to carry on its
business as now being conducted.  Premier is duly qualified or licensed to do
business and is in good standing in each jurisdiction in which the nature of its
business or the ownership or leasing of its properties makes such qualification
or licensing necessary, other than in such jurisdictions where the failure to be
so qualified or licensed (individually or in the aggregate) could not reasonably
be expected to have a material adverse effect with respect to Premier.

          (b)  Corporate Authorization.  The execution, delivery and performance
               -----------------------                                          
by Premier of this Purchase Agreement and the consummation by Premier of the
transactions contemplated hereby have been duly authorized by all necessary
corporate action, including by resolution of the Board of Directors of Premier.
Premier has the requisite corporate power, authority and legal capacity to enter
into and perform all of its obligations under this Purchase Agreement and to
consummate the Transactions hereunder.  This Purchase Agreement has been duly
executed and delivered by Premier and constitutes a valid and binding agreement
of Premier, enforceable against Premier in accordance with its terms (subject to
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
transfer and other similar laws affecting creditors' rights generally from time
to time in effect and to general principles of equity, including concepts of
materiality, reasonableness, good faith and fair dealing, regardless of whether
in a proceeding or equity or at law).

          (c)  No Conflict.  Other than the filing of a Form 4 and an amendment
               -----------

and no permit, authorization, consent or approval of, any Governmental Authority
is necessary for the execution of this Purchase Agreement or the Registration
Rights Agreement by Premier and the consummation by Premier of the transactions
contemplated hereby and thereby, except for such filings the failure of which to
be made, individually or in the aggregate, could not reasonably be expected to
have a material adverse effect on Premier, and its Subsidiaries, taken as a
whole, or to prevent or materially delay the consummation of the transactions
contemplated hereby and thereby. Neither the execution and delivery of this
Purchase Agreement or the Registration Rights Agreement by Premier nor the
consummation by Premier of the transactions contemplated hereby or thereby, nor
compliance by Premier with any of the provisions hereof or thereof (i) conflicts
with or results in any breach of the 

                                      -7-

 
Articles of Incorporation or bylaws of Premier, (ii) contravenes, conflicts with
or would constitute a violation of any provision of any law, regulation,
judgment, injunction, order or decree binding upon Premier, or (iii) constitutes
a default under or gives rise to any right of termination, cancellation or
acceleration of any right or obligation of Premier or any of its Subsidiaries or
to a loss of any benefit to which Premier or any of its Subsidiaries is entitled
under any provision of any agreement, contract or other instrument binding on
Premier or any of its Subsidiaries or any license, franchise, permit or other
similar authorization held by Premier or any of its Subsidiaries, except, in the
case of clauses (ii) and (iii), for any such contravention, conflict, violation,
default, termination, cancellation, acceleration or loss that would not have a
material adverse effect on Premier or any of its Subsidiaries taken as a whole.

          (d) No Required Vote.  No vote of the holders of any class of the
              ----------------

Agreement or the Transactions.

          (e) Reservation of Premier Common Stock.  The Premier Common Stock and

Warrant Consideration to be issued to Seller as Purchase Consideration pursuant
to this Purchase Agreement and any Premier Common Stock purchasable upon
exercise of such Warrant Consideration, have been reserved solely for issuance
and delivery to Seller, and when issued, will be duly and validly issued, fully
paid and nonassessable, and such issuances will not violate any pre-emptive
rights under applicable law, Premier's Articles of Incorporation or bylaw,
contract or agreement, or otherwise.

          (f) Limitations on Transferability.   Premier acknowledges that the
              ------------------------------                                 
Securities are being acquired from an Affiliate of the Company without
registration under the Securities Act or the securities laws of any other
applicable jurisdiction, and that such Securities are being sold to Premier
pursuant to an exemption thereto.  Premier is acquiring the Securities solely
for its own account, for investment purposes only, and not with an intent or
view to their distribution within the meaning of Section 2(11) of the Securities
Act. Premier understands that such Securities may not be freely transferable
without registration under the Securities Act or the securities laws of any
other applicable jurisdiction unless subsequently registered or an exemption
therefrom is available.

              ---------

and delivery of this Purchase Agreement by the Seller nor the consummation by
the Seller of the Transactions nor compliance by the Seller with the provisions
hereof conflicts with or results in a breach of any agreement entered into by
the Seller, other than such agreements, the conflict with or breach of which,
individually or in the aggregate, could not reasonably be expected to prevent or
materially delay the consummation of the Transactions.

          (b) Corporate Authorization.  The execution, delivery and performance
              -----------------------                                          
by Seller of this Purchase Agreement and the consummation by Seller of the
transactions contemplated hereby have been duly authorized by all necessary
corporate action, including by resolution of the Board of Directors of Seller.

constitutes a valid and binding agreement of Seller, enforceable against Seller
in accordance with its terms (subject to applicable bankruptcy, insolvency,
reorganization, moratorium, fraudulent transfer and other similar laws affecting
creditors' rights generally from time to time in effect and to general
principles of equity, including concepts of materiality, reasonableness, good
faith and fair dealing, regardless of whether in a proceeding or equity or at

          (c) Title to Securities.  At the Closing the Seller will be the direct
              -------------------

right to acquire, whether presently exercisable or at any time in the future,

exercisable or exchangeable for Securities including, but not limited to, any
options held by Seller.   No person has the right to acquire, and the Seller is
not a party to any contract, understanding, commitment, arrangement or other
agreement to sell, transfer or otherwise dispose of, any shares of Company
Common Stock owned by or issuable to the Seller.  At the Closing, the Seller
will have good and valid title to the Securities, free and clear of any Liens or
Restrictions and it will have the full legal right, power and authority to
assign, transfer and deliver such Securities to Premier pursuant hereto.  At the
Closing, the Seller will have the sole voting power, and sole power of
disposition, with respect to all of such Securities and there will be no
restrictions on the Seller's ability to transfer such Securities.

          (d) No Conflict.  Except for the filing of a Form 4 with the
              -----------

Agreement by the Seller and the consummation

the failure of which to be made, individually or in the aggregate, could not
reasonably be expected to have a material adverse effect on the Seller, if any,
taken as a whole, or to prevent or materially delay the consummation of the
Transactions.

          (e) Investment Intention.  The Seller is acquiring the Stock
              --------------------

investment and not with a view to resale or distribution or with any present
intention of distributing or selling the same.  The  Seller is fully aware that
the Stock Consideration and the Warrant Consideration have not been registered
under the Securities Act or under any applicable state securities laws, and are
being offered and sold in reliance on exemptions from the registration
requirements of the Securities Act and all such laws.  The Seller is an
"accredited investor" as such term is defined in Regulation D promulgated under
the Securities Act.  The Seller is able to bear the economic risk of the
investment in the Stock Consideration and the Warrant Consideration and has such
knowledge and experience in financial and business matters, and knowledge of the
business of Premier, as to be capable of evaluating the merits and risks of a
prospective investment.

          (f) Limitations on Transferability.  Seller acknowledges that it may
              ------------------------------                                  
not transfer any of the Stock Consideration or the Warrant Consideration
received by it pursuant hereto unless and until the same are registered under
the Securities Act and any applicable state securities laws, or unless an
exemption from such registration is available.  Seller acknowledges that
transferability of the Stock Consideration and Warrant Consideration also is
limited by the terms of this Purchase Agreement.

arbitration in Irvine, 

                                     -15-

 
California initiated by a party by a written notice to the other party demanding
arbitration and specifying the claim to be arbitrated. Such arbitration shall be
conducted pursuant to the Expedited Procedures of the Commercial Arbitration
Rule (the "Rules") of the American Arbitration Association ("AAA), with the
following modifications. The party initiating the arbitration (the "Claimant")
shall appoint its arbitrator in its request for arbitration (the "Request"). The
other party (the "Respondent") shall appoint its arbitrator within 15 Business
Days of receipt of the Request and shall notify the Claimant of such appointment
in writing. If the Respondent fails to appoint an arbitrator within such 15
Business Day period, the arbitrator named in the Request shall decide the
controversy or claim as a sole arbitrator. Otherwise, the two arbitrators
appointed by the parties shall appoint a third arbitrator within 15 Business
Days after the Respondent has notified Claimant of the appointment of the
Respondent's arbitrator. When the third arbitrator has accepted the appointment,
the two party-appointed arbitrators shall promptly notify the parties of such
appointment. If the two arbitrators appointed by the parties fail or are unable
to so appoint a third arbitrator, then the appointment of the third arbitrator
shall be made by the AAA, which shall promptly notify the parties of the
appointment. The third arbitrator shall act as chairperson of the panel. Upon
appointment of the third arbitrator, the arbitrators shall proceed to commence
and conduct all proceedings promptly and in accordance with the Rules. The
arbitral award shall be in writing and shall be final and binding on the parties
to the arbitration. The arbitrator shall be instructed to award costs, including
reasonable attorneys' fees and disbursements, which shall be paid by the party
against whom the award is entered. Judgment upon the award may be entered by any
court having jurisdiction thereof or having jurisdiction over the parties or
their assets, without review of the merits of the award.

               (i)  by mutual consent of Premier and the Seller in writing;

               (ii) by either Premier or the Seller if the Closing shall not
     have occurred prior to February 27, 1998 (other than due to the failure of
     the party seeking to terminate this Purchase Agreement to perform its
     obligations under this Purchase Agreement required to be performed at or
     prior to such date);

                                     -16-

     directly or indirectly, has material assets or operations shall have issued
     an order, decree or taken any other action permanently enjoining,
     restraining or otherwise prohibiting the Transactions, and such order,
     decree, ruling or other action shall have become final and nonappealable;
     or

               (iv)  by Premier, if after the date of this Purchase Agreement
     the Company issues (A) any shares of Company Common Stock (other than upon
     the conversion, exercise or exchange of securities outstanding on the date
     of this Purchase Agreement that are convertible into or exercisable or
     exchangeable for shares of Company Common Stock) or (B) any securities
     convertible into or exercisable or exchangeable for shares of Company
     Common Stock which result in the percentage of Company Common Stock
     beneficially held by the Seller, together with the percentage of Company
     Common Stock beneficially held by Premier falling below 50.1% of the
     ownership of all Company Common Stock (assuming the conversion, exercise or
