               CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES

SECTION 2.01 THE MERGER

    At the Effective Time, by virtue of the Merger and without any action on the
part of Acquiror, Acquiror Sub, the Company or the holders of any of the
securities referred to in this Section 2.01:

    (a)  COMMON STOCK.  Subject to Section 2.06, (i) each share of Company
Common Stock (excluding any shares described in Section 2.01(c) and (f)) issued
and outstanding immediately prior to the Effective Time shall cease to be
outstanding and shall be converted into and exchanged for the right to receive a
portion of a share of common stock, par value $0.01, of Acquiror ("Acquiror
Common Stock") equal to the Exchange Ratio (as defined below). The shares of
Acquiror Common Stock issuable to the holders of Company Common Stock pursuant
hereto is sometimes referred to herein, collectively, as the "Merger
Consideration". All such shares of Company Common Stock shall cease to be
outstanding and shall automatically be canceled and retired and shall cease to
exist, and each certificate previously evidencing any such shares shall
thereafter represent only the right to receive the Merger Consideration. Except
as otherwise provided herein or by applicable law, the holders of certificates
previously evidencing such shares of Company Common Stock outstanding
immediately prior to the Effective Time shall cease to have any rights with
respect to such shares of Company Common Stock. Each such certificate previously
evidencing such shares of Company Common Stock shall be exchanged for the number
of shares indicated in the certificate provided by the Company pursuant to
Section 6.08 in accordance with the provisions of Section 2.02 multiplied by the
Exchange Ratio, rounded up to the nearest whole number.

    The "Exchange Ratio" shall be determined as follows:

        (i) if the Acquiror Stock Price is less than or equal to $56.00 per
    share and greater than or equal to $44.00 per share, the Exchange Ratio
    shall be equal to the quotient obtained by dividing the Company Stock Value
    by the Acquiror Stock Price;

        (ii) if the Acquiror Stock Price is less than $44.00 per share and
    greater than or equal to $39.60 per share, the Exchange Ratio shall be equal
    to the quotient obtained by dividing the Company Stock Value by $44.00;

       (iii) if the Acquiror Stock Price is greater than $56.00 per share and
    less than or equal to $61.60 per share, the Exchange Ratio shall be equal to
    the quotient obtained by dividing the Company Stock Value by $56.00;

        (iv) if the Acquiror Stock Price is greater than $61.60 per share,
    (A) Acquiror may terminate this Merger Agreement pursuant to
    Section 8.01(d)(i), unless the Company makes a "Company Floating Rate
    Election" prior to the Scheduled Closing Date, in which case the Exchange
    Ratio shall be equal to the quotient obtained by dividing (x) the product of
    the Company Stock Value multiplied by 1.10 by (y) the Acquiror Stock Price
    or (B) in the event that Acquiror does not terminate this Agreement pursuant
    to clause (A) and the Company does not make a Company Floating Rate
    Election, the Exchange Ratio shall be equal to the quotient obtained by
    dividing the Company Stock Value by $56.00;

        (v) if the Acquiror Stock Price is less than $39.60 per share,
    (A) Company may terminate this Merger Agreement pursuant to
    Section 8.01(d)(ii), unless the Acquiror makes an "Acquiror Floating Rate
    Election" prior to the Scheduled Closing Date, in which case the Exchange
    Ratio shall be equal to the quotient obtained by dividing (x) the product of
    the Company Stock Value multiplied by 0.90 by (y) the Acquiror Stock Price
    or (B) in the event that Company does not terminate this Agreement pursuant
    to clause (A) and Acquiror does not make the Acquiror

                                      A-3
<PAGE>
    Floating Rate Election, the Exchange Ratio shall be equal to the quotient
    obtained by dividing the Company Stock Value by $44.00.

    (b)  CERTAIN DEFINITIONS.  For purposes of this Merger Agreement, (i) the
term "Acquiror Stock Price" shall mean the average of the closing sale prices of
a share of Acquiror Common Stock as reported on the New York Stock Exchange
("NYSE") for the ten (10) consecutive trading days ending with and including the
second trading day immediately preceding the date of the Scheduled Closing Date;
(ii) the term "Acquiror Floating Rate Election" shall mean an election made by
Acquiror to use the Exchange Ratio calculated pursuant to
Section 2.01(a)(v)(A); and (iii) the term "Company Floating Rate Election" shall
mean an election made by the Company to use the Exchange Ratio calculated
pursuant to Section 2.01(a)(iv)(A).

    (c)  TREASURY STOCK.  All shares of capital stock of the Company held in the
treasury of the Company immediately prior to the Effective Time shall be
canceled and extinguished without any conversion thereof and no amount shall be
delivered or deliverable in exchange therefor.

    (d)  ACQUIROR SUB STOCK.  Each share of common stock, par value $.01 per
share, of Acquiror Sub issued and outstanding immediately prior to the Effective
Time ("Acquiror Sub Stock") shall be converted into and exchanged for one
(1) duly and validly issued, fully paid and nonassessable share of common stock
of the Surviving Corporation.

    (e)  [Intentionally Omitted].

    (f)  DISSENTING SHARES.  Notwithstanding anything in this Merger Agreement
to the contrary and unless otherwise provided by applicable law, shares of
Company Common Stock that are issued and outstanding immediately prior to the
Effective Time and that are owned by Company Stockholders who have properly
demanded payment of the fair value of their stock (the "Dissenting Shares")
within the meaning of Section 262 of Delaware Law shall not be converted into
the right to receive the Merger Consideration unless and until such Company
Stockholders shall have failed to perfect or shall have effectively withdrawn
their demand, or lost their right of payment under applicable law. If any such
Company Stockholder shall have failed to perfect or shall have effectively
withdrawn or lost such right of payment, each share of Company Common Stock held
by such Company Stockholder shall thereupon be deemed converted into the right
to receive and exchangeable for, at the Effective Time, the Merger Consideration
pursuant to Section 2.02 of this Merger Agreement. Subject to the terms and
conditions of this Merger Agreement, at and after the Effective Time, any holder
of shares of Company Common Stock who complies with Section 262 of Delaware Law
(a "Company Dissenting Stockholder") shall be entitled to obtain payment from
Surviving Corporation of the fair value of such Company Dissenting Stockholder's
shares of Company Common Stock as determined pursuant to Delaware Law; PROVIDED,
HOWEVER, that, to the extent permissible under Delaware Law, no such payment
shall be made unless and until such Company Dissenting Stockholder has
surrendered to the Exchange Agent the Certificate representing the shares of
Company Common Stock for which payment is being made.

    (g)  PROCEDURE WITH RESPECT TO DISSENTING SHARES.  Company shall give
Acquiror (i) prompt notice of any written notice of intent to demand payment for
shares filed pursuant to Section 262 of Delaware Law received by Company,
withdrawals of such notices, and any other instruments served in connection with
such notices pursuant to the relevant provisions of Delaware Law and received by
Company and (ii) the opportunity to direct all negotiations and proceedings with
respect to such notices under Delaware Law consistent with the obligations of
Company thereunder. Company shall not, except with the prior written consent of
Acquiror (which shall not be unreasonably withheld), (A) make any payment with
respect to any such notice, (B) offer to settle or settle any such notices or
(C) waive any failure to timely deliver a written notice in accordance with the
Delaware Law.

                                      A-4

    (h)  FLOATING RATE ELECTION.  The Company and the Acquiror shall deliver the
Company Floating Rate Election or the Acquiror Floating Rate Election, as the
case may be, by notice to the other Party prior to the Scheduled Closing Date.
The Company Floating Rate Election and the Acquiror Floating Rate Election may
be delivered notwithstanding the fact that the other Party has not then elected
to terminate this Merger Agreement pursuant to Section 2.01(a) and
Section 8.01(d), in which event the other Party shall not be entitled to
terminate this Merger Agreement pursuant to Section 2.01(a) or Section 8.01(d).

    (a)  EXCHANGE AGENT.  As soon as reasonably practicable after the Effective
Time, but in no event later than four (4) business days after the Effective Time
(assuming the Company has provided to Acquiror an electronic list of the names,
addresses, and tax identification numbers of the Company Stockholders and the
information provided in the certificate in Section 6.08 at least one
(1) business day prior to the Effective Time), Acquiror shall deposit with an
exchange agent designated by Acquiror and reasonably acceptable to Company (the
"Exchange Agent") pursuant to an exchange agreement in the form attached hereto
as Exhibit C, for the benefit of the former holders of shares of Company Common
Stock (excluding any shares described in Section 2.01(c)), for issuance and
payment in accordance with this Article II the shares of Acquiror Common Stock
(but not including the Escrow Stock) issuable pursuant to Section 2.01(a) (such
shares of Acquiror Common Stock being hereinafter referred to as the "Exchange
Fund"). Acquiror shall cause the Exchange Agent, pursuant to irrevocable
instructions, to deliver Acquiror Common Stock contemplated to be delivered
pursuant to Section 2.01(a) out of the Exchange Fund within three (3) business
days of the Exchange Agent's receipt of all information and documentation
required pursuant to Section 2.02(b). The Exchange Fund shall not be used for
any purpose other than as set forth in this Section 2.02(a).

    (b)  PAYMENT PROCEDURES.  As soon as reasonably practicable after the
Effective Time, but in no event later than four (4) business days after the
Effective Time (assuming the Company has provided to Acquiror an electronic list
of the names, addresses, and tax identification numbers of the Company
Stockholders and the information provided in the certificate in Section 6.08 at
least one (1) business day prior to the Effective Time), Acquiror shall cause
the Exchange Agent to mail to each record holder, as of the Effective Time, of
an outstanding certificate or certificates (each a "Certificate" and
collectively, the "Certificates") that immediately prior to the Effective Time
evidenced outstanding shares of Company Common Stock (excluding any shares
described in Sections 2.01(c)): (i) a form letter of transmittal and
(ii) instructions for use in effecting the surrender of the Certificates for
payment therefor. The Exchange Agent shall provide to the Company (for delivery
to the Company Stockholders) all such documentation in advance of the Effective
Time, but in any event not less than one (1) week prior to the Closing Date.
Upon surrender to the Exchange Agent of a Certificate, together with such letter
of transmittal duly executed and any other required documents, the holder of
such Certificate shall be entitled to receive in exchange therefor the
applicable consideration set forth in Section 2.01, and such Certificate shall
forthwith be canceled. In the event of a surrender of a Certificate representing
shares of Company Common Stock which are not registered in the transfer records
of the Company under the name of the Person surrendering such Certificate, a
certificate representing the proper number of shares of Acquiror Common Stock
may be issued to a Person other than the Person in whose name the Certificate so
surrendered is registered if (x) such Certificate shall be properly endorsed or
otherwise be in proper form for transfer to the Person surrendering such
Certificate and requesting such issuance, (y) such Person surrendering such
Certificate and requesting such issuance shall pay any transfer or other Taxes
required by reason of the issuance of shares of Acquiror Common Stock to a
Person other than the registered holder of such Certificate or shall establish
to the satisfaction of Acquiror that such Taxes have been paid or are not
applicable, and (z) such Person surrendering such certificate shall, if required
by Acquiror, have such Person's signature

                                      A-5
<PAGE>
guaranteed by a bank, brokerage firm or other financial intermediary that is a
member of a medallion guarantee program. Until surrendered in accordance with
the provisions of this Section 2.02, each Certificate shall represent for all
purposes only the right to receive the applicable consideration set forth in
Section 2.01, without any interest thereon.

    (c)  ISSUANCES TO AFFILIATES.  Notwithstanding anything herein to the
contrary, any Certificate surrendered for exchange by any "affiliate" of the
Company (as that term is used in SEC Accounting Series Release Nos. 130 and 135
and Rule 145 of the rules and regulations of the SEC under the Securities Act)
shall not be exchanged until Acquiror shall have received a signed agreement
from such "affiliate" as provided in Section 5.12 hereof.

    (d)  NO FURTHER RIGHTS IN STOCK.  All shares of Acquiror Common Stock issued
upon the surrender for exchange of Certificates in accordance with the terms of
Sections 2.01 and 2.02 hereof shall be deemed to have been issued in full
satisfaction of all rights pertaining to the shares of Company Common Stock
theretofore represented by such Certificates, and there shall be no further
registration of transfer on the stock transfer books of the Surviving
Corporation of the shares of Company Common Stock represented by such
Certificates which were outstanding immediately prior to the Effective Time. If,
after the Effective Time, any such Certificates are presented to Acquiror, the
Surviving Corporation or the Exchange Agent for any reason, they shall be
canceled and exchanged as provided in this Article II, except as otherwise
provided by law.

    (e)  [Intentionally Omitted]

    (f)  TERMINATION OF EXCHANGE FUND.  Any portion of the Exchange Fund that
remains undistributed to the holders of Company Common Stock for twelve
(12) months after the Effective Time shall be delivered to Acquiror, upon
demand, and any holder of Company Common Stock that has not theretofore complied
with this Article II shall thereafter look only to the Surviving Corporation and
Acquiror for the Merger Consideration to which such holder is entitled pursuant
hereto.

    (g)  NO LIABILITY.  Neither Acquiror nor the Surviving Corporation shall be
liable to any holder of shares of Company Common Stock for any Acquiror Common
Stock or cash delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.

    (h)  WITHHOLDING OF TAX.  Acquiror or the Exchange Agent shall be entitled
to deduct and withhold from the applicable amount of the Merger Consideration
otherwise issuable to any former holder of Company Common Stock such amounts as
Acquiror (or any Affiliate thereof) or the Exchange Agent are required to deduct
and withhold with respect to the making of such payment under the Code, or any
provision of state, local or foreign Tax law. To the extent that amounts are so
withheld by Acquiror (or any Affiliate thereof) or the Exchange Agent, such
withheld amounts shall be treated for all purposes of this Merger Agreement as
having been paid to the former holder of Company Common Stock in respect of whom
such deduction and withholding was made by Acquiror (or any Affiliate thereof)
or the Exchange Agent.

    (i)  LOST, STOLEN OR DESTROYED CERTIFICATES.  In the event any Certificate
evidencing shares of Company Common Stock shall have been lost, stolen or
destroyed, upon the making of an affidavit setting forth that fact by the Person
claiming such lost, stolen or destroyed Certificate and the granting of a
reasonable indemnity against any claim that may be made against Acquiror or the
Exchange Agent with respect to such Certificate (and if required by Acquiror in
the case of any Certificate or Certificates from any Company Stockholder
representing more than seven thousand five hundred (7,500) shares of Company
Common Stock, the posting by such Person of a bond, in such reasonable amount as
Acquiror may direct), Acquiror shall cause the Exchange Agent to pay to such
Person the applicable amount of the Merger Consideration with respect to such
lost, stolen or destroyed Certificate.

                                      A-6
<PAGE>
    (j)  DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES OF ACQUIROR COMMON
STOCK.  No dividends or other distributions declared or made after the Effective
Time with respect to Acquiror Common Stock with a record date after the
Effective Time shall be paid to the holder of any unsurrendered Certificate with
respect to the shares of Acquiror Common Stock evidenced thereby until the
holder of such Certificate shall properly surrender such Certificate in
accordance with the requirements of Section 2.02(b). Subject to the effect of
escheat, tax or other applicable laws, following surrender of any such
Certificate, there shall be paid to the holder of the certificates evidencing
whole shares of Acquiror Common Stock issued in exchange therefor, without
interest, (i) promptly the amount of dividends or other distributions with a
record date after the Effective Time and theretofore paid with respect to such
whole shares of Acquiror Common Stock, and (ii) at the appropriate payment date,
the amount of dividends or other distributions, with a record date after the
Effective Time but prior to surrender and a payment date occurring after
surrender, payable with respect to such whole shares of Acquiror Common Stock.

    (k)  APPOINTMENT OF STOCKHOLDERS' REPRESENTATIVES.  Michael B. Alexander,
Sigmund H. Goldblum and Peter Schulte shall, by virtue of the Merger, be
appointed attorneys-in-fact and authorized and empowered to act, for and on
behalf of any or all of the Company Stockholders (with full power of
substitution in the premises), in connection with the provisions of Article IX
as they relate to the Company and the Company Stockholders generally, and such
other matters as are reasonably necessary for the consummation of the
transactions contemplated hereby including, without limitation, (i) to
compromise on their behalf with Acquiror any claims asserted thereunder,
(ii) to execute and deliver on behalf of the Company Stockholders any documents
or agreements contemplated by or necessary or desirable in connection with this
Merger Agreement and (iii) to take such further actions including coordinating
and administering post-closing matters related to the rights and obligations of
the Company Stockholders as are authorized in this Merger Agreement (the above
named representatives, as well as any subsequent representative(s) of the
Company Stockholders appointed by the Company Stockholders being referred to
herein as the "Stockholders' Representatives"). The Stockholders'
Representatives shall not be liable to any Company Stockholder, Acquiror, the
Surviving Corporation or their respective Affiliates or any other Person with
respect to any action taken or omitted to be taken by the any of Stockholders'
Representatives in their role as Stockholders' Representatives under or in
connection with this Merger Agreement unless such action or omission results
from or arises out of fraud, gross negligence, willful misconduct or bad faith
on the part of the Stockholders' Representatives. Acquiror, Acquiror Sub and the
Surviving Corporation shall be entitled to rely on such appointment and treat
such Stockholders' Representatives, or any one of them, as the duly appointed
attorney-in-fact of each Company Stockholder. Each Company Stockholder who votes
in favor of the Merger pursuant to the terms hereof, by such vote and without
any further action, and each Company Stockholder who receives Merger
Consideration in connection with the Merger, by acceptance thereof and without
any further action, confirms such appointment and authority. In the event
Acquiror receives conflicting instructions from different Stockholders'
Representatives, Acquiror shall be permitted to take no action with respect
thereto until it receives written instructions signed by all Stockholders'
Representatives or directed by court order.

SECTION 2.03 STOCK OPTIONS

    (a) As of the Effective Time, each outstanding Option shall be converted
into an option to acquire Acquiror Common Stock as provided in this
Section 2.03. Following the Effective Time, each Option shall continue to have,
and shall be subject to, the terms and conditions of each agreement pursuant to
which such Option was subject immediately prior to the Effective Time
(including, in the case of each Option granted under the Company's 1998 Long
Term Incentive Plan, the terms and conditions of the Company's 1998 Long Term
Incentive Plan under which such Option was granted), except that: (i) each
Option (as converted pursuant to this Section 2.03) shall be exercisable for
that number of whole shares of Acquiror Common Stock equal to the product of
(A) the aggregate number

                                      A-7
<PAGE>
of shares of Company Common Stock for which such Option was exercisable at the
Effective Time, multiplied by (B) the Exchange Ratio, rounded up to the nearest
whole share (provided that all references in such Company Stock Option Plans and
the agreement under which such Option was granted to the Company shall be
references to Acquiror and references to the Company's Common Stock shall be
references to Acquiror Common Stock); and (ii) the exercise price per share of
Acquiror Common Stock issuable pursuant to each Option (as converted pursuant to
this Section 2.03) shall be equal to the exercise price per share of Company
Common Stock under such Option at the Effective Time divided by the Exchange
Ratio, rounded to the nearest whole cent.

    (b) The assumption and substitution of Options as provided herein shall not
give the holders of such Options additional benefits or additional (or
accelerated) vesting rights that they did not have immediately prior to the
Effective Time or relieve the holders of such Options from any obligations or
restrictions applicable to their Options or the shares obtainable upon exercise
of the Options. The adjustment provided herein with respect to any Options that
are "incentive stock options" (as defined in Section 422 of the Code) shall be
and is intended to be, effected in a manner that is consistent with continued
treatment of such Options as "incentive stock options" under Section 424(a) of
the Code. The duration and other terms of the converted options provided for in
this Section 2.03 shall be the same as the Options except that all references to
the Company shall be references to Acquiror and references to the Company's
Common Stock shall be references to Acquiror Common Stock. Acquiror shall take
all corporate action necessary to reserve for issuance, at all times any
converted Options provided for in this Section 2.03 are outstanding, a
sufficient number of shares of Acquiror Common Stock for delivery upon the
exercise of such converted Options. The Company will take such action as shall
be reasonably necessary (including but not limited to obtaining waivers from
holders of Options) so that each Option that was unvested or subject to a
repurchase option, risk of forfeiture or other condition under any applicable
Company Stock Option Plans immediately prior to the Effective Time shall
continue to be subject to such vesting, repurchase, forfeiture or other
conditions with respect to the Acquiror Common Stock that may be issuable with
respect thereto after the occurrence of the Effective Time or the consummation
of the transactions contemplated by this Merger Agreement. As of the Effective
Time, the Company shall effect the termination of each other outstanding
unexpired and unexercised option to purchase shares of Company Common Stock.

SECTION 2.04 CERTAIN ADJUSTMENTS

    If between the date hereof and the Effective Time, the outstanding shares of
Company Common Stock or of Acquiror Common Stock shall be changed into a
different number of shares by reason of any reclassification, recapitalization,
split-up, combination or exchange of shares, or any dividend payable in stock or
other securities shall be declared thereon with a record date within such
period, the Exchange Ratio (and any other references herein to a price per share
of Acquiror Common Stock) shall be adjusted accordingly to provide the same
economic effect as contemplated by this Merger Agreement prior to such
reclassification, recapitalization, split-up, combination, exchange or dividend.

SECTION 2.05 CLOSING

    Subject to the terms and conditions of this Merger Agreement, the closing of
the Merger (the "Closing" and the date of such Closing, the "Scheduled Closing
Date") will take place on the second Business Day after the satisfaction of the
latest to occur or, if permissible, waiver of the conditions set forth in
Article VII of this Merger Agreement at the offices of Hogan & Hartson L.L.P.,
8300 Greensboro Drive, Suite 1100, McLean, Virginia 22102, unless another date
or place is agreed to in writing by the Parties.

SECTION 2.06 ESCROW STOCK; DETERMINATION OF CLOSING ADJUSTMENT

    (a)  ESCROW STOCK.  When making the issuances of Acquiror Common Stock
pursuant to Section 2.01(a) above, Acquiror shall withhold from the Company
Stockholders a number of shares of Acquiror Common Stock equal to the quotient
of five percent (5%) of the Transaction Value divided by the Acquiror Stock
Price (the "Escrow Stock"). The Escrow Stock will be placed in escrow as
security for the performance of the indemnity obligations of the Company
Stockholders under Section 9.02 of this Merger Agreement and to pay Acquiror any
Closing Adjustment required to be paid to Acquiror pursuant to this
Section 2.06, all pursuant to the terms and conditions of an escrow agreement
among Acquiror, the Surviving Corporation, the Stockholders' Representatives and
First Union National Bank or another escrow agent designated by Acquiror and
reasonably acceptable to the Company (the "Escrow Agent"), in form attached
hereto as Exhibit D (the "Escrow Agreement"). The Escrow Stock shall be
registered in the name of the Escrow Agent as nominee for the Company
Stockholders. The Merger Consideration otherwise distributable as of the
Effective Time to each Company Stockholder in connection with the Merger as
provided in Section 2.01(a) shall be proportionately reduced to reflect the
Escrow Stock required to be deposited in Escrow pursuant to this
Section 2.06(a) and the Escrow Agreement, and such Escrow Stock shall be
released to the Company Stockholders or Acquiror, as the case may be, only in
accordance with the terms of this Merger Agreement and the Escrow Agreement. The
fees of the Escrow Agent shall be paid by Acquiror. On the earlier to occur of
(i) five (5) business days after the final determination of the Closing
Adjustment and the Loss Adjustment pursuant to Section 2.06(b) (including,
without limitation, final resolution of any disputes with respect thereto) or
(ii) ninety (90) days after Closing, the Escrow Agent shall deliver to the
Company Stockholders, pro-rata in accordance with the number of shares of
Company Common Stock held by each such Company Stockholder immediately prior to
the Effective Time, the Escrow Stock, after deducting therefrom an amount of
Escrow Stock having a value equal to the sum (which shall not be less than zero)
of the Closing Adjustment, if any, and the Loss Adjustment, if any, and shall
deliver to Acquiror an amount of Escrow Stock having a value equal to such sum;
PROVIDED, HOWEVER, that in the event of any dispute over the sum of the Closing
Adjustment and the Loss Adjustment pursuant to Section 2.06(b), the Escrow Stock
having a value equal to the amount of any disputed Closing Adjustment and Loss
Adjustment (together with a number of shares of Escrow Stock which are, in
Acquiror's reasonable judgment, necessary to cover any expenses of Acquiror
necessary to resolve such dispute) need not be delivered until such dispute is
finally resolved. For purposes of this Section 2.06, the value of each share of
Escrow Stock shall be equal to the Closing Acquiror Stock Price.

    (b)  DETERMINATION OF CLOSING ADJUSTMENT AND LOSS ADJUSTMENT.  The "Closing
Adjustment" shall equal (i) the amount by which the Net Debt of the Company and
the Company Subsidiaries as of the Closing Date is greater or less than
(ii) the Estimated Net Debt as set forth in the certificate required to be
delivered pursuant to Section 7.02(k) of this Merger Agreement. The "Loss
Adjustment" shall equal the amount of any Losses for which Acquiror Indemnified
Persons are entitled to indemnification pursuant to Section 9.02. The Company
will use its best efforts to close its books and records for the period ending
on the Closing Date within five (5) days after the Closing Date and shall
deliver to the Acquiror or, at the request of the Acquiror, to Acquiror and
Arthur Andersen LLP, such books and records as shall be requested by Acquiror or
Arthur Andersen LLP to enable Arthur Andersen LLP to perform an audit of the
consolidated financial statements of the Company as of the Closing Date and to
determine the amount of the Closing Adjustment and the Loss Adjustment. Upon
receipt of such books and records, the Acquiror shall use its best efforts to
cause Arthur Andersen LLP to complete an audit of the consolidated financial
statements of the Company in order to provide Acquiror the information necessary
to calculate the amount of the Closing Adjustment and the Loss Adjustment within
sixty (60) days following receipt of the books and records of the Company.
Acquiror shall deliver to the Stockholders' Representatives a draft copy of such
audited financial statements and the draft

                                      A-9
<PAGE>
determination of the amount of the Closing Adjustment and the Loss Adjustment
promptly upon receipt of such items from Arthur Andersen LLP. The Stockholders'
Representatives shall have the right to review and copy the computations and
review workpapers used in connection with the preparation of the audited
financial statements after providing Arthur Andersen LLP with written releases
reasonably acceptable to Arthur Andersen LLP and the computation of the Closing
Adjustment and the Loss Adjustment. If the Stockholders' Representatives
disagree with the determination of the Closing Adjustment or the Loss
Adjustment, the Stockholders' Representatives shall so notify the Acquiror in
writing within ten (10) days after the date of their receipt of the audited
financial statements and the computation of the Closing Adjustment and the Loss
Adjustment, specifying in detail any point of disagreement; PROVIDED, HOWEVER,
that if the Stockholders' Representatives fail to notify the Acquiror in writing
of the Stockholders' Representatives' disagreement within such ten (10) day
period, the determination of the Closing Adjustment and the Loss Adjustment
shall be final, conclusive and binding on the Parties for purposes of
determining the amount of the Escrow Stock to be delivered to Company
Stockholders pursuant to this Section 2.06, PROVIDED, FURTHER, HOWEVER, that the
sum of the Closing Adjustment and the Loss Adjustment shall not exceed five
percent (5%) of the Transaction Value. The Acquiror and the Stockholders'
Representatives shall negotiate in good faith to resolve any such disagreement.
It is the intent of the Parties hereto that upon final determination of the
Closing Adjustment, if any, and the Loss Adjustment, if any, the net amount of
such adjustments, provided such amount is in Acquiror's favor, shall be paid to
Acquiror from the Escrow Stock pursuant to this section. There shall be no
adjustment in the case of a net sum in the Company's favor but the escrow stock
shall be distributed to the Company Stockholders as provided above.

    (c)  RESOLUTION OF CLOSING ADJUSTMENT.  If any such disagreement with
respect to the Closing Adjustment cannot be resolved by the Acquiror and the
Stockholders' Representatives within fifteen (15) days after the Stockholders'
Representatives have received notice from the Acquiror in accordance with
Section 2.06(b) of the existence of such disagreement, the Acquiror and the
Stockholders' Representatives shall jointly select a nationally recognized
independent public accounting firm (which has not performed any service since
January 1, 1996 for either the Company or the Acquiror or any of their
respective Affiliates (the "Accounting Firm")), to act as an arbitrator to
resolve as expeditiously as possible all points of disagreement with respect to
the Closing Adjustment (or, in the event they are unable to agree, either may
request the San Diego, CA office of the American Arbitration Association to make
such selection, which shall be final and binding on the Parties). All
determinations made by the Accounting Firm with respect to the Closing
Adjustment shall be final, conclusive and binding on the Parties hereto. Each
party shall be responsible for its fees and expenses, as well as one-half of the
fees and expenses of the Accounting Firm, incurred in connection with the
resolution of the Closing Adjustment; PROVIDED, HOWEVER, that any such fees and
expenses incurred on behalf of the Company Stockholders may be paid from any
excess Escrow Stock (that is, any Escrow Stock remaining after the final
distribution to Acquiror of Escrow Stock, if any, in respect of the Closing
Adjustment or the Loss Adjustment) pursuant to the Escrow Agreement.

    (d)  RESOLUTION OF LOSS ADJUSTMENT.  If any such disagreement with respect
to the Loss Adjustment cannot be resolved by the Acquiror and the Stockholders'
Representatives within fifteen (15) days after the Stockholders' Representatives
have received notice from the Acquiror in accordance with Section 2.06(b) of the
existence of such disagreement, the Acquiror and the Stockholders'
Representatives shall submit the matter to the San Diego, CA office of the
American Arbitration Association ("AAA") for binding arbitration to be conducted
in accordance with the AAA commercial arbitration rules in effect at the time
such matter is submitted. If any such matter is submitted to the AAA as provided
herein, (A) each of the Acquiror and the Stockholders' Representatives will
furnish to AAA such workpapers and other documents and information as AAA may
request and will be afforded the opportunity to present to AAA any material
relevant to the matter, (B) the determination by AAA, as set forth in a notice
delivered to the Acquiror and the Stockholders' Representatives by

                                      A-10
<PAGE>
AAA, will be binding and conclusive on such parties and (C) the non-prevailing
party shall be responsible for the fees and expenses incurred in connection with
the resolution of the Loss Adjustment; provided, however, that any such fees and
expenses that are to be paid by the Company Stockholders may be paid from any
excess Escrow Stock (that is, any Escrow Stock remaining after the final
distribution to Acquiror of Escrow Stock, if any, in respect of the Closing
Adjustment or Loss Adjustment) pursuant to the Escrow Agreement.

the right to use all Intangible and Other Property used in the business of
Company and Company Subsidiaries, as presently conducted or as proposed to be
conducted, except for such Intangible and Other Property the loss of the use of
which is not reasonably likely, individually or in the aggregate (together with

unrelated Persons may involve such infringement or violation) and (ii) no claim
has been asserted, and Company is not aware of any claim which can be asserted,
by any Person against Company or Company Subsidiaries with respect to the use of

Adverse Effect. Unless specifically noted in Section 3.07 of the Company

to receive a royalty or similar payment, or has any other monetary rights, in
respect of any item of Intangible and Other Property of Company or any Company

Letter, no Person (other than employees of Company or any Company Subsidiary)

Letter),

                                      A-15

to have a Company Material Adverse Effect. The Merger will not violate any
provision of any Agreements relating to any of the Intangible or Other Property.

parties thereto. Company and each Company Subsidiary have in all material
respects performed all material obligations thereunder required to be performed
by any of them to date. To the knowledge of Company, no party is in default in
any material respect under any of the foregoing, and there has not occurred any
event which (whether with or without notice, lapse of time or the happening or

parcel of the Real Property, and no structures of any kind encroach on the Real
Property, except as would not materially detract from the use of the Real
Property.

legally enforceable in accordance with its terms against Company and, to the
knowledge of Company, the Company Contracts are valid, binding and enforceable
obligations of the other parties thereto, except as such enforceability may be
subject to the effects of any applicable bankruptcy, insolvency, fraudulent
conveyance, reorganization, moratorium or similar Laws affecting creditors'
rights generally or subject to the effects of general equitable principles
(whether considered in a proceeding in equity or at law). Company has complied
with all of the provisions of such Company Contracts and is not in default
thereunder, and there has not occurred any event which (whether with or without
notice, lapse of time, or the happening or occurrence of any other event) would
constitute such a default, and the execution of this Merger Agreement by Company
and its performance hereunder will not cause, or result in, a breach or default
under any Company Contract in each case which would reasonably be expected to
have a Company Material Adverse Effect. There has not been (A) any failure by

Contract to comply with all material provisions thereof which default or failure
to perform would reasonably be expected to have a Company Material Adverse
Effect, (B) any default by Company or, to the knowledge of Company, any other
party thereunder, which default or failure to perform would reasonably be

activity or lawsuits would not reasonably be expected to have a Company Material
Adverse Effect or (b) any union or other collective bargaining unit representing

compliance with all Laws relating to employment or the workplace, including,
without limitation, Laws relating to wages, hours, collective bargaining, safety
and health, work authorization, equal employment opportunity, immigration,

ERISA and the Code and any other applicable Laws, including the terms of such
plans.

    (c) All liabilities (contingent or otherwise) under any Company Benefit Plan
are fully accrued or reserved against in the Company Financial Statement in

(without regard to any waiver) provided for in Section 412 of the Code.

    (d) Neither Company nor any Company Subsidiary has any obligations for

payment (including, without limitation, severance, golden parachute or
otherwise) becoming due to any person under any Company Benefit Plan or
otherwise, (ii) increase any benefits otherwise payable under any Company
Benefit Plan or (iii) result in any acceleration of the time of payment or
vesting of any such benefits.

Section 401(a) or 401(k) of the Code or qualified as a voluntary employees'
beneficiary association under Sections 501(a) and 501(c)(9) of the Code has
received a favorable determination letter from the IRS that it is so qualified
and so exempt, and no fact or event has occurred that could adversely affect
such qualified or exempt status.

                                      A-20
<PAGE>
    (g) Company and each Company Subsidiary have not incurred any material

whether or not such Taxes are or were disputed), whether or not shown on any Tax
Return.

    (b) The Company and each Company Subsidiary have filed on a timely basis all
material Company Tax Returns that it was required to file. All such Company Tax
Returns were accurate and complete in all material respects. None of Company or
any Company Subsidiary is the beneficiary of any extension of time within which

been made (which has not been satisfactorily resolved) by an authority in a
jurisdiction where Company or any Company Subsidiary does not file Company Tax
Returns that any one of them is or may be subject to taxation by that
jurisdiction. None of Company or any Company Subsidiary has given any currently
effective waiver of any statute of limitations in respect of Taxes or agreed to

Taxes required to have been withheld and paid in connection with amounts paid or
owing to any employee, independent contractor, creditor, stockholder or other
third party.

circumstances which could give rise to a reasonable expectation that any
authority may assess any additional Taxes for any period for which Company Tax
Returns have been filed. There is no dispute or claim concerning any liability
for Taxes of Company or any Company Subsidiary either (i) claimed or raised by
any authority in writing or (ii) as to which Company has knowledge based upon
personal contact with any agent of such authority. Company and each Company
Subsidiary has delivered to the Acquiror copies of, and Section 3.16 of the
Company Disclosure Letter sets forth a complete and accurate list of, Company
Tax Returns filed with respect to the taxable periods of Company and any Company
Subsidiary ended on or after December 31, 1996; indicates those Company Tax
Returns that have been audited; and indicates those Company Tax Returns that
currently are the subject of an audit.

    (e) The unpaid Taxes of Company and any Company Subsidiary (i) did not, as

signed agreement referred to in Section 5.12(a), except to the extent permitted
by, and in accordance with, SEC Accounting Series Release 135 and SEC Staff

account for the transactions contemplated by this Merger Agreement as a "pooling
of interests" in accordance with GAAP, Accounting Principles Board Opinion

register the transfer of any shares of Acquiror Common Stock unless such

policies of the SEC, and each of the Company and Acquiror agrees that it shall
take no action that would cause such accounting treatment not to be obtained.

fail to undertake to defend such Third Party Claim, or (iii) there is a
reasonable probability that such Third Party Claim may materially and adversely

other party's written consent (which consent shall not be unreasonably withheld
or delayed), settle or compromise such Third Party Claim or consent to entry of
any judgment which does not include as an unconditional term thereof the giving
by the claimant or the plaintiff to the Indemnified Party of a release from all
liability in respect of such Third Party Claim in form and substance
satisfactory to the Indemnified Party; (ii) in the event that a party hereto
undertakes defense of such Third Party Claim in accordance with this
Section 9.03, the other parties, by counsel or other representative of their own
choosing and at their sole cost and expense, shall have the right to participate
in the defense, compromise or settlement thereof and each party and its counsel
and other representatives shall cooperate with the other party and its counsel

the defense of such Third Party Claim in accordance with this Section 9.03 shall
have an obligation to keep the other parties informed of the status of the
defense of such Third Party Claim and furnish the other parties with all
documents, instruments and information that the other parties shall reasonably
request in connection therewith.
