             UNILAB CORPORATION AND SUBSIDIARIES
          NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                         (UNAUDITED)
                        
1. Management Opinion
                        
   In the opinion of management, the accompanying unaudited
   interim financial statements reflect all adjustments which are
   necessary to present fairly the financial position, results of
   operations and cash flows for the interim periods reported.  All
   such adjustments made were of a normal recurring nature, except
   for the extraordinary charge of $3.5 million recorded in the first
   quarter of 1996, as discussed in note 3 below, and the legal charge
   of $1.2 million recorded in the first quarter of 1995, as discussed in
   note 4 below.
                        
   The accompanying interim financial statements and related notes
   should be read in conjunction with the consolidated financial
   statements of Unilab Corporation ( "Unilab" or the "Company")
   and related notes as contained in the Annual Report on Form 10-K
   for the year ended December 31, 1995.
                        
2. Net Income (Loss) Per Share
                        
   Net income (loss) per share is computed by dividing net income
   (loss) less preferred stock dividends by the weighted average
   number of common shares outstanding plus common stock
   equivalents, which include options and warrants, during the period. 
   The assumed conversion of the convertible preferred stock is
   excluded from the calculation since its effect would be immaterial.
                        
3. Long-Term Debt
                        
   In March 1996, the Company completed an offering for $120.0
   million of Senior Notes (the "Senior Notes").  Interest on the
   Senior Notes is 11% and is payable on April 1st and October 1st
   of each year, commencing October 1, 1996.  The Senior Notes are
   due April 2006 and the Company is not required to make any
   mandatory redemption or sinking fund payment with the respect to
   the Senior Notes prior to maturity.
                        
   The proceeds from the Senior Notes offering were used to retire
   outstanding borrowings    under the Company's then existing bank
   term loan and revolving line of credit facility (the "Existing Credit
   Facility") in the principal amount of $102.1 million, plus accrued
   interest.   In connection with the Senior Notes offering, the
   Company replaced the Existing Credit Facility with a new credit
   facility which provides for a $20.0 million revolving working
   capital line of credit.     
                        
   In connection with the Senior Notes offering, the Company
   incurred approximately $5.0 million of financing costs (of which
   approximately $4.2 million had been paid by March 31, 1996). 
   The debt financing costs are deferred and amortized, using the
   interest method, over the term of the related debt.  Upon
   completion of the Senior Notes offering, the Company wrote-off
   $3.5 million of deferred financing costs related to the Company's
   previous credit agreements.  The $3.5 million charge has been
   shown as an extraordinary loss from the early extinguishment of
   debt in the statement of operations.
                        
   The Senior Notes were issued at a discount of 99.242% per note. 
   The aggregate discount on the Senior Notes approximated  $0.9
   million and is charged to operations as additional interest expense
   over the life of the Senior Notes using the interest method.
                        
   The Senior Notes are not redeemable prior to April 1, 2001, after
   which the Senior Notes will be redeemable at any time at the
   option of the Company, in whole or in part, at various redemption
   prices as set forth in the indenture covering such Senior Notes (the
   "Indenture"),  plus accrued and unpaid interest, if any, to the date
   of redemption.  In addition, at any time prior to April 1, 1999, the
   Company may redeem up to $42.0 million in aggregate principal
   amount of the Senior Notes with the net proceeds of one or more
   public offerings of common stock of the Company, at a redemption
   price of 110% of the principal amount thereof, plus accrued and
   unpaid interest, if any, to the redemption date.
                        
   In the event of a change in control, as defined in the Indenture,
   holders of the Senior Notes will have the right to require the
   Company to purchase their notes, in whole or in part, at a price
   equal to 101% of the aggregate principal amount thereof, plus
   accrued and unpaid interest, if any, to the date of purchase.
                        
   The Notes are general unsecured obligations of the Company and
   rank pari passu in right of payment with all unsubordinated
   indebtedness of the Company.  In addition, the Indenture limits the
   ability of the Company to incur additional indebtedness, under
   certain circumstances.
                        
   In March 1996, the Company recognized an expense of
   approximately $80,000 related to the termination of its interest rate
   swap and cap agreements.
                        
4. Legal Charge
                        
   In December 1993, the Company was named as a defendant in The
   Trylon Corporation v. MetWest Inc., Unilab Corporation and Does
   1 through 30.  The lawsuit alleged that Unilab breached a contract,
   and the implied covenants of good faith and fair dealing in
   connection with that contract with respect to the sales, marketing
   and distribution of blue white speculite lightsticks, a product
   designed for use in connection with PAP smears to screen for
   cervical cancer and precancerous conditions in women.  Plaintiff
   sought an unspecified amount of damages.   In February 1994, the
   case was referred to arbitration in accordance with the arbitration
   clause of the contract between the parties.  In September 1995, the
   arbitrator rendered an award in favor of The Trylon Corporation
   ("Trylon") of approximately $437,000.  In November 1995, the
   arbitrator reduced the award to Trylon to approximately $374,000
   (comprised of approximately $313,000 principal award plus
   interest of approximately $61,000) and granted Trylon's request for
   payment of legal fees of approximately $1.4 million.  The
   Company recorded a $1.2 million charge during the first quarter of
   1995 related to the expected cost, consisting primarily of legal fees,
   in defending itself against such lawsuit and another $2.0 million
   charge during the fourth quarter of 1995 reflecting the costs
   associated with the conclusion of this arbitration, including the fees
   of Trylon's counsel and counsel for the Company.

      Income taxes                              8           3

  In addition, the Company issued Unilab common shares valued at
  $1.0 million in the first quarter of 1996 in partial payment of the
  purchase price for an acquisition made in 1993.

                         Results of Operations
                          
                         Results of Operations
                        
       Quarter Ended March 31, 1996 Compared with Quarter Ended
                            March 31, 1995
                        
       Revenue increased to $51.5 million for the three months ended
       March 31, 1996 from $42.2 million for the comparable prior year
       period, representing an increase of $9.3 million or 22.0%.  The
       increase was the result of additional specimen volume generating
       approximately $10.2 million offset by decreases in reimbursement
       levels of approximately $0.9 million.  The increase in specimen
       volume was primarily attibutable to growth in the Company's core
       business of $4.5 million and revenue from the acquisition of
       Medical Laboratory Network, Inc. ("MLN") completed in May
       1995 of $5.7 million.  The decrease in reimbursement levels is
       primarily due to a reduction in the national fee caps for Medicare
       reimbursement in January 1996 and a general softening in
       reimbursement levels across most payor groups.
                        
       Salaries, wages and benefits increased to $17.6  million for the
       three months ended March 31, 1996 from $13.8 million for the
       comparable prior year period.  As a percentage of  revenue,
       salaries, wages and benefits increased to 34.2% in 1996 from
       32.6% in 1995.  Such increase is consistent with the higher trends
       recognized by the Company in the second half of 1995.
                        
       Supplies expense increased to $6.6 million for the three months
       ended March 31, 1996 from $5.2 million from the comparable
       prior year period.  As a percentage of revenue, supplies expense
       increased to 12.8% in 1996 from 12.3% in 1995.  Such increase
       was the result of increased specimen volume and slightly higher
       supplies cost.
                        
       Other operating expenses increased to $13.0 million for the three
       months ended March 31, 1996 from $9.8 million from the
       comparable prior year period.  As a percentage of revenue, other
       operating expenses increased to  25.3% in 1996 from 23.3% in
       1995.  Such increase was primarily due to an increase in lab
       subcontracting expenses due to increases in fees charged by, and
       volume sent to, outside reference laboratories and an increase in
       bad debt expenses, both being consistent with the higher trends
       recognized by the Company in the second half of 1995.
                        
       In December 1993, the Company was named as a defendant in The
       Trylon Corporation v. MetWest Inc., Unilab Corporation and Does
       1 through 30.  The lawsuit alleged that Unilab breached a contract,
       and the implied covenants of good faith and fair dealing in
       connection with that contract with respect to the sales, marketing
       and distribution of blue white speculite lightsticks, a product 
       designed for use in connection with PAP smears to screen for
       cervical cancer and precancerious conditions in women.  Plaintiff
       sought an unspecified amount of damages.  In February 1994, the
       case was referred to arbitration in accordance with the arbitration
       clause of the contract between the parties.  In September 1995, the
       arbitrator rendered an award in favor of  Trylon of approximately
       $437,000.  In November 1995, the arbitrator reduced the award to
       Trylon to approximately $374,000 (comprised of approximately
       $313,000 principal award plus interest of approximately $61,000)
       and granted Trylon's request for payment of legal fees of
       approximately $1.4 million (payment of such legal fees of $1.4
       million was made in the first quarter of 1996).  The Company
       recorded a $1.2 million charge during the first quarter of 1995
       related to the expected cost, consisting primarily of legal fees, in
       defending itself against such lawsuit and another $2.0 million
       charge during the fourth quarter of 1995 reflecting the costs
       associated with the conclusion of this arbitration, including the fees
       of Trylon's counsel and counsel for the Company.
                        
       Selling, general and administrative expenses increased to $11.0
       million for the three months ended March 31, 1996 from $8.3
       million from the comparable prior year period.  As a percentage of
       revenue, selling, general and administrative expenses increased to
       21.3% in 1996 from 19.6% in 1995.  Such increase was primarily
       due to personnel added in sales and marketing throughout the latter
                     half of 1995.
                        
       Amortization and depreciation expense increased to $2.8 million
       for the three months ended March 31, 1996 from $1.9 million from
       the comparable prior year period primarily due to the additional
       amortization expense of approximately $0.4 million resulting from
       the acquisition of MLN and additional depreciation expense of
       approximately $0.4 million primarily resulting from depreciation
       started in the second half of 1995 on approximately $3.0 million
       of computer equipment and software. 
                        
       Third party interest expense increased to $2.8 million for the three
       months ended March 31, 1996 from $1.6 million for the
       comparable prior year period primarily due to increased
       borrowings by the Company used to finance the acquisition of
       MLN and to pay related transaction fees and expenses in May 1995
       and increased indebtedness incurred by the Company under the
       Senior Notes offering in March 1996.
                        
       Related party interest income of $375,000 for the three months
       ended March 31, 1996 reflects interest income on the $15.0 million
       promissory note the Company received upon the sale of its equity
       investment in UGL.  The sale was effective June 30, 1995 and the
       Company ceased recording equity earnings from UGL after April 30, 1995.
                        
       Upon completion of the Senior Notes offering, the Company wrote
       off $3.5 million of deferred financing costs related to the
       Company's previous credit agreements.
                        
       Liquidity and Capital Resources
                        
       Net cash used by operating activities was $4.5 million for the three
       months ended March 31, 1996 and reflects a decrease of $4.7
       million over the comparable prior year period when net cash
       provided by operating activities was $0.2 million.  The decrease
       was primarily due to a reduction in the net income before
       extraordinary item and the payment of legal fees of approximately
       $1.4 million in connection with the conclusion of the Trylon
       arbitration.
                        
       Net cash provided by financing activities was $15.8 million for the
       three months ended March 31, 1996, primarily resulting from
       approximately $4.4 million of borrowing under the Company's
       previous credit facility used for working capital purposes and
       approximately $17.0 million of additional indebtedness incurred in
       connection with the Senior Notes offering offset primarily by $1.5
       million of scheduled principal repayments under the Company's
       previous credit facility and payment of approximately $4.2 million
       of financing costs incurred in connection with the Senior Notes
       offering.
                        
       Net cash used by investing activities was $1.5 million for the three
       months ended March 31, 1996, primarily resulting from $1.0
       million of capital expenditures and $0.5 million of payments made
       on an acquisition completed in 1995.
                        
       The Company has $9.8 million of cash and cash equivalents on
       hand at March 31, 1996.  Cash on hand and additional borrowing
       capabilities of $20.0 million under a working capital line of credit
       are expected to be sufficient to meet anticipated operating
       requirements, debt repayments and provide funds for capital
       expenditures and working capital for the foreseeable future.

PART II - OTHER INFORMATION
                        
Item 1.      Legal Proceedings

        Unilab, MetWest and certain unnamed persons or entities were
        named as defendants in The Trylon Corporation v. MetWest Inc.,
        Unilab Corporation and Does 1 through 30, filed on or about
        December 8, 1993 in the Superior Court of the State of California
        for the County of Los Angeles.  The plaintiff alleged that MetWest
        and Unilab breached a contract, and the implied covenants of good
        faith and fair dealing in connection with that contract with respect
        to the sales, marketing and distribution by MetWest and Unilab of
        Blue-White Speculite Lightsticks, a Trylon product designed for
        use in connection with PAP smears to screen for cervical cancer
        and precancerous conditions in women.  Plaintiff sought an
        unspecified amouont of damages.  In February 1994, the case was
        referred to arbitration before the American Arbitration Association
        in Los Angeles County in accordance with the arbitration clause of
        the contract between the parties. In September 1995, the arbitrator
        rendered an award in favor of Trylon of approximately $437,000. 
        In November 1995, the arbitrator reduced the award to Trylon to
        approximately $374,000 (comprised of approximately $313,000
        principal award plus interest of approximately $61,000) and
        granted Trylon's request for reimbursement of legal fees of
        approximately $1.4 million.  The Company appealed that award of
        legal fees to the California Superior Court, which declined to
        overturn the award and confirmed the arbitrator's decision in
        February 1996.  The Company recorded a $1.2 million charge
        during the first quarter of 1995 related to the expected cost,
        consisting primarily of legal fees, in defending itself against such
        lawsuit and another $2.0 million charge in the fourth quarter of
        1995, reflecting the costs associated with the conclusion of this
        arbitration, including the fees of Trylon's counsel and counsel for
        the Company.

of Equity Interests in any of the Company's Restricted
Subsidiaries or the sale of Equity Interests in any of its

present value (discounted at the rate of interest implicit in such
transaction, determined in accordance with GAAP) of the
obligation of the lessee for net rental payments during the
remaining term of the lease included in such sale and leaseback
transaction (including any period for which such lease has been
extended or may, at the option of the lessor, be extended).

amount equal to (i) the greater of (A) $20 million and (B) 80%

120 days past due minus (ii) the aggregate amount of all
permanent reductions of Senior Revolving Debt required to be
made pursuant to clause (a) of the second paragraph of Section
4.10 hereof.  To the extent that information is not available as
to the amount of accounts receivable or inventory as of a
specific date, the Company may utilize the most recent

corporation, corporate stock, (ii) in the case of a partnership,
partnership interests (whether general or limited), (iii) in the

                  THE NOTES

Section 2.01.   Form and Dating.

       The Notes and the Trustee's certificate of
authentication shall be substantially in the form of Exhibit A
hereto, the terms of which are incorporated in and made a part
of this Indenture.  The Notes may have notations, legends or
endorsements approved as to form by the Company and
required by law, stock exchange rule, agreements to which the
Company is subject, or usage.  Each Note shall be dated the
date of its authentication.  The Notes shall be issuable in
registered form, without coupons, and only in denominations of
$1,000 and integral multiples thereof.

Section 2.02.   Execution and Authentication.

       One Officer of the Company shall sign the Notes
for the Company by manual or facsimile signature.  

       If an Officer of the Company whose signature is
on a Note no longer holds that office at the time the Note is
authenticated, the Note shall nevertheless be valid.

       A Note shall not be valid until authenticated by the
manual signature of a Responsible Officer of the Trustee.  The
signature of the Trustee shall be conclusive evidence that the
Note has been authenticated under this Indenture.  The form of
Trustee's certificate of authentication to be borne by the Notes
shall be substantially as set forth in Exhibit A hereto.

       The Trustee shall, upon a written order of the
Company signed by two Officers of the Company, authenticate
Notes for original issue up to an aggregate principal amount at
maturity stated in the Notes.  The aggregate principal amount at
maturity of Notes outstanding at any time shall not exceed such
amount except as provided in Section 2.07 hereof.

       The Trustee may appoint an authenticating agent
acceptable to the Company to authenticate Notes.  Unless
limited by the terms of such appointment, an authenticating
agent may authenticate Notes whenever the Trustee may do so. 
Each reference in this Indenture to authentication by the
Trustee includes authentication by such agent.  An
authenticating agent has the same rights as an Agent to deal
with the Company or an Affiliate of the Company.

Section 2.03.   Registrar and Paying Agent.

       The Company shall maintain (i) an office or
agency where Notes may be presented for registration of
transfer or for exchange (including any co-registrar, the
"Registrar") and (ii) an office or agency where Notes may be
presented for payment ("Paying Agent") within the City of and
the State of New York or, at the option of the Company,
payment of interest may be made by check mailed to the
Holders at their respective addresses set forth in the register of
Holders.  The Registrar shall keep a register of the Notes and
of their transfer and exchange.  The Company may appoint one
or more co-Registrars and one or more additional paying
agents.  The term "Paying Agent" includes any additional
paying agent.  The Company may change any Paying Agent,
Registrar or co-Registrar without prior notice to any Holder. 
The Company shall notify the Trustee and the Trustee shall
notify the Holders of the name and address of any Agent not a
party to this Indenture.  The Company may act as Paying
Agent, Registrar or co-Registrar.  The Company shall enter
into an appropriate agency agreement with any Agent not a
party to this Indenture, which shall be subject to any
obligations imposed by the provisions of the TIA.  The
agreement shall implement the provisions of this Indenture that
relate to such Agent.  The Company shall notify the Trustee of
the name and address of any such Agent.  If the Company fails
to maintain a Registrar or Paying Agent, or fails to give the
foregoing notice, the Trustee shall act as such, and shall be
entitled to appropriate compensation in accordance with Section
7.07 hereof.

       The Company initially appoints the Trustee as
Registrar, Paying Agent and agent for service of notices and
demands in connection with the Notes.

Section 2.04.   Paying Agent to Hold Money in Trust.

       The Company shall require each Paying Agent
other than the Trustee to agree in writing that the Paying Agent
shall hold in trust for the benefit of the Holders or the Trustee
all money held by the Paying Agent for the payment of
principal of, premium, if any, and interest on the Notes, and
shall notify the Trustee of any Default by the Company in
making any such payment.  While any such Default continues,
the Trustee may require a Paying Agent to pay all money held
by it to the Trustee and to account for any funds disbursed. 
The Company at any time may require a Paying Agent to pay
all money held by it to the Trustee.  Upon payment over to the
Trustee, the Paying Agent (if other than the Company) shall
have no further liability for the money delivered to the Trustee. 
If the Company acts as Paying Agent, it shall segregate and
hold in a separate trust fund for the benefit of the Holders all
money held by it as Paying Agent.

Section 2.05.   Lists of Holders of the Notes.

       The Trustee shall preserve in as current a form as
is reasonably practicable the most recent list available to it of
the names and addresses of Holders and shall otherwise comply
with TIA Section 312(a).  If the Trustee is not the Registrar, the
Company shall furnish to the Trustee at least seven (7) Business
Days before each interest payment date and at such other times
as the Trustee may request in writing a list in such form and as
of such date as the Trustee may reasonably require of the
names and addresses of Holders, including the aggregate
principal amount at maturity of the Notes held by each thereof,
and the Company shall otherwise comply with TIA Section 312(a). 

Section 2.06.   Transfer and Exchange.

       When Notes are presented to the Registrar with a
request to register the transfer or to exchange them for an equal
principal amount at maturity of Notes of other denominations,
the Registrar shall register the transfer or make the exchange if
its requirements for such transactions are met; provided,
however, that any Note presented or surrendered for
registration of transfer or exchange shall be duly endorsed or
accompanied by a written instruction of transfer in form
satisfactory to the Issuer and the Trustee duly executed by the
Holder thereof or by his attorney duly authorized in writing. 
To permit registrations of transfer and exchanges, the Company
shall issue and the Trustee shall authenticate Notes at the
Registrar's request, subject to such rules as the Trustee may
reasonably require.

       Neither the Company nor the Registrar shall be
required to (i) issue, register the transfer of or exchange Notes
during a period beginning at the opening of business on a
Business Day fifteen (15) days before the day of any selection
of Notes for redemption or purchase under Section 3.02 hereof
and ending at the close of business on the day of selection,
(ii) register the transfer of or exchange any Note so selected for
redemption in whole or in part, except the unredeemed portion
of any Note being redeemed in part or (iii) register the transfer
or exchange of a Note between a record date and the next
succeeding interest payment date. 

       No service charge shall be made to any Holder for
any registration of transfer or exchange (except as otherwise
expressly permitted herein), but the Company may require
payment of a sum sufficient to cover any transfer tax or other
governmental charge payable in connection therewith (other
than such transfer tax or similar governmental charge payable
upon exchanges pursuant to Sections 2.10, 3.06 or 9.05 hereof,
which shall be paid by the Company).

       Prior to due presentment to the Trustee for
registration of the transfer of any Note, the Trustee, any Agent
and the Company may deem and treat the Person in whose
name any Note is registered as the absolute owner of such Note
for the purpose of receiving payment of principal of, premium,
if any, and interest on such Note and for all other purposes
whatsoever, whether or not such Note is overdue, and none of
the Trustee, any Agent nor the Company shall be affected by
notice to the contrary.

Section 2.07.   Replacement Notes.

       If any mutilated Note is surrendered to the
Trustee, or the Company and the Trustee receive evidence to
their satisfaction of the destruction, loss or theft of any Note
and the ownership thereof, the Company shall issue and the
Trustee, upon the written order of the Company signed by two
Officers of the Company, shall authenticate a replacement Note
if the Trustee's requirements for replacements of Notes are
met.  In every case the applicant for a replacement Note shall
furnish to the Company and to the Trustee and any agent of the
Company or the Trustee, an indemnity bond as may be
required in the reasonable judgment of the Trustee and the
Company to protect the Company, the Trustee, each Agent and
each authenticating agent from any loss which any of them may
suffer if a Note is replaced.  The Company and the Trustee
may charge the applicant for their expenses in replacing a
Note.

       Every replacement Note is an additional
Obligation of the Company and shall be entitled to all of the
benefits of (but shall be subject to all the limitations of rights
set forth in) this Indenture equally and ratably with all other
Notes duly issued hereunder.

Section 2.08.   Outstanding Notes.

       The Notes outstanding at any time are all the
Notes authenticated by the Trustee except for those cancelled
by it, those delivered to it for cancellation and those described
in this Section 2.08 as not outstanding.  If a Note is replaced
pursuant to Section 2.07 hereof, it ceases to be outstanding
unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser.  If the principal
amount at maturity of any Note is considered paid under
Section 4.01 hereof, it ceases to be outstanding and interest on
it ceases to accrue.  Subject to Section 2.09 hereof, a Note does
not cease to be outstanding because the Company or an
Affiliate of the Company holds the Note.

Section 2.09.   Treasury Notes.

       In determining whether the Holders of the required
principal amount at maturity of Notes have concurred in any
direction, waiver or consent, Notes owned by the Company or
any Affiliate of the Company shall be considered as though not
outstanding, except that for purposes of determining whether
the Trustee shall be protected in relying on any such direction,
waiver or consent, only Notes which a Responsible Officer of
the Trustee actually knows to be so owned shall be so
considered.  Notwithstanding the foregoing, Notes that are to
be acquired by the Company or an Affiliate of the Company
pursuant to an exchange offer, tender offer or other agreement
shall not be deemed to be owned by such entity until legal title
to such Notes passes to such entity.

Section 2.10.   Temporary Notes.

       Until definitive Notes are ready for delivery, the
Company may prepare and the Trustee shall authenticate
temporary Notes.  Temporary Notes shall be substantially in
the form of definitive Notes but may have variations that the
Company and the Trustee consider appropriate for temporary
Notes.  Without unreasonable delay, the Company shall
prepare and the Trustee, upon receipt of the written order of
the Company signed by two Officers of the Company, shall
authenticate definitive Notes in exchange for temporary Notes. 
Until such exchange, temporary Notes shall be entitled to the
same rights, benefits and privileges as definitive Notes.

Section 2.11.   Cancellation.

       The Company at any time may deliver Notes to
the Trustee for cancellation.  The Registrar and Paying Agent
shall forward to the Trustee any Notes surrendered to them for
registration of transfer, exchange or payment.  The Trustee
shall cancel all Notes surrendered for registration of transfer,
exchange, payment, replacement or cancellation.  Subject to
Section 2.07 hereof, the Company may not issue new Notes to
replace Notes that it has redeemed or paid or that have been
delivered to the Trustee for cancellation.  All cancelled Notes
held by the Trustee shall be destroyed and certification of their
destruction delivered to the Company.

Section 2.12.   Defaulted Interest.

       If the Company defaults in a payment of interest
on the Notes, the Company shall pay the defaulted interest in
any lawful manner plus, to the extent lawful, interest payable
on the defaulted interest, to the Persons who are Holders on a
subsequent special record date, which date shall be at the
earliest practicable date but in all events at least five (5)
Business Days prior to the payment date, in each case at the
rate provided in the Notes and in Section 4.01 hereof.  The
Company shall fix or cause to be fixed each such special record
date and payment date, and shall, promptly thereafter, notify
the Trustee of any such date.  At least fifteen (15) days before
the special record date, the Company (or the Trustee, in the
name of and at the expense of the Company) shall mail to
Holders, at their addresses as they appear on the register of
Notes maintained by the Registrar, a notice that states the
special record date, the related payment date and the amount of
such interest to be paid. 

Section 2.13.   Record Date.

       The record date for purposes of determining the
identity of Holders entitled to vote or consent to any action by
vote or consent authorized or permitted under this Indenture
shall be determined as provided for in TIA Section 316(c).

Section 2.14.   CUSIP Number.

       The Company in issuing the Notes may use a
"CUSIP" number and, if it does so, the Trustee shall use the
CUSIP number in notices of redemption or exchange as a
convenience to Holders; provided that any such notice may
state that no representation is made as to the correctness or
accuracy of the CUSIP number printed in the notice or on the
Notes and that reliance may be placed only on the other
identification numbers printed on the Notes.  The Company
will promptly notify the Trustee of any change in the CUSIP
number.

Section 2.15.   Computation of Interest.

       Interest on the Notes will be computed on the basis
of a 360-day year comprised of twelve 30-day months.


                 ARTICLE 3 
      REDEMPTION AND OFFERS TO PURCHASE

Section 3.01.   Notices to Trustee.

       If the Company elects to redeem Notes pursuant to
the optional redemption provisions of Section 3.07 hereof, it
shall furnish to the Trustee, at least 30 days but not more than
60 days before a redemption date, an Officers' Certificate
setting forth (i) the Section of this Indenture pursuant to which
the redemption shall occur, (ii) the redemption date, (iii) the
principal amount at maturity of Notes to be redeemed and (iv)
the redemption price.

       If the Company is required to make an offer to
purchase Notes pursuant to the provisions of Sections 3.09 or
4.15 hereof, it shall furnish to the Trustee, at least 30 days
before the scheduled purchase date, an Officers' Certificate
setting forth (i) the Section of this Indenture pursuant to which
the offer to purchase shall occur, (ii) the terms of the offer, (iii)
the purchase price, (iv) the principal amount at maturity of the
Notes to be purchased, (v) the purchase date, and (vi) further
setting forth, as applicable, a statement to the effect that (a) the
Company or one of its Restricted Subsidiaries has effected an
Asset Sale and there are Excess Proceeds aggregating more
than $5.0 million and the amount of such Excess Proceeds or
(b) a Change of Control has occurred.

Section 3.02.   Selection of Notes to Be Purchased or
                Redeemed.

       If less than all of the Notes are to be redeemed at
any time, the Trustee shall select the Notes to be redeemed
among the applicable Holders of the Notes in compliance with
the requirements of the principal national securities exchange,
if any, on which the Notes are listed or, if the Notes are not so
listed, on a pro rata basis, by lot or by such other method the
Trustee deems fair and appropriate; provided that no Notes of
$1,000 or less shall be redeemed in part.  

       The Trustee shall promptly notify the Company in
writing of the Notes selected for redemption and, in the case of
any Note selected for partial purchase or redemption, the
principal amount at maturity thereof to be purchased or
redeemed.  Notes and portions of Notes selected shall be in
amounts of $1,000 or whole multiples of $1,000; except that if
all of the Notes of a Holder are to be purchased or redeemed,
the entire outstanding amount of Notes held by such Holder,
even if not a multiple of $1,000, shall be purchased or
redeemed.  Except as provided in the preceding sentence,
provisions of this Indenture that apply to Notes called for
redemption also apply to portions of Notes called for
redemption.

Section 3.03.   Notice of Redemption.

       At least 30 days but not more than 60 days before
a redemption date, the Company shall mail or cause to be
mailed, by first class mail, postage prepaid, a notice of
redemption to Holders whose Notes are to be redeemed at their
last addresses as they shall appear upon the registry books. 
The notice mailed in the manner herein provided shall be
conclusively presumed to have been duly given whether or not
the Holder receives such notice.  In any case, failure to give
such notice by mail or any defect in the notice to the Holder of
any Note shall not affect the validity of the proceeding for the
redemption of any other Note.

       The notice shall identify the Notes to be redeemed
and shall state:

          (a)   the redemption date; 

          (b)   the redemption price (including accrued
                interest to the redemption date);  

          (c)   the principal amount at maturity of Notes
                to be redeemed;

          (d)   if any Note is being redeemed in part,
                the portion of the principal amount at
                maturity of such Note to be redeemed
                and that, after the redemption date upon
                surrender of such Note, a new Note or
                Notes in principal amount at maturity
                equal to the unredeemed portion shall be
                issued upon cancellation of the original
                Note;

          (e)   the name and address of the Paying
                Agent;

          (f)   that Notes called for redemption must be
                surrendered to the Paying Agent to
                collect the redemption price; 

          (g)   that, unless the Company defaults in
                making such redemption payment,
                interest on Notes called for redemption
                ceases to accrue on and after the
                redemption date; and

          (h)   that no representation is made as to the
                correctness or accuracy of the CUSIP
                number, if any, listed in such notice or
                printed on the Notes.

       At the Company's request, the Trustee shall give
the notice of redemption in the Company's name and at its
expense; provided, however, that the Company shall have
delivered to the Trustee, at least 45 days prior to the
redemption date, an Officers' Certificate requesting that the
Trustee give such notice and setting forth the information to be
stated in such notice as provided in the preceding paragraph.  

Section 3.04.   Effect of Notice of Redemption.

       Once notice of redemption is mailed in accordance
with Section 3.03 hereof, Notes called for redemption become
irrevocably due and payable on the redemption date at the
redemption price, plus accrued and unpaid interest, if any, to
such date.  A notice of redemption may not be conditional.

Section 3.05.   Deposit of Redemption or Purchase Price.

       On or before 10:00 a.m. (New York City time) on
each redemption date or the date on which Notes must be
accepted for purchase pursuant to Section 3.09 or 4.15, the
Company shall deposit with the Trustee or with the Paying
Agent in immediately available funds money sufficient to pay
the redemption or purchase price of and unpaid and accrued
interest, if any, on all Notes to be redeemed or purchased on
that date.  The Trustee or the Paying Agent shall promptly
return to the Company any money deposited with the Trustee
or the Paying Agent by the Company in excess of the amounts
necessary to pay the redemption or purchase price of (including
any applicable premium), and accrued interest on, all Notes to
be redeemed or purchased.

       If Notes called for redemption or tendered in an
Asset Sale Offer or Change of Control Offer are paid or if the
Company has deposited with the Trustee or Paying Agent
money sufficient to pay the redemption or purchase price of,
and unpaid and accrued interest, if any, on all Notes to be
redeemed or purchased on and after the redemption or purchase
date, interest shall cease to accrue on the Notes or the portions
of Notes called for redemption or tendered and not withdrawn
in an Asset Sale Offer or Change of Control Offer (regardless
of whether certificates for such securities are actually
surrendered).  If a Note is redeemed or purchased on or after
an interest record date but on or prior to the related interest
payment date, then any accrued and unpaid interest shall be
paid to the Person in whose name such Note was registered at
the close of business on such record date.  If any Note called
for redemption or subject to an Asset Sale Offer or Change of
Control Offer shall not be so paid upon surrender for
redemption or purchase because of the failure of the Company
to comply with the preceding paragraph, interest shall be paid
on the unpaid principal, from the redemption or purchase date
until such principal is paid, and to the extent lawful on any
interest not paid on such unpaid principal, in each case at the
rate provided in the Notes and in Section 4.01 hereof. 

Section 3.06.   Notes Redeemed or Purchased in Part. 

       Upon surrender of a Note that is redeemed or
purchased in part, the Company shall issue and the Trustee
shall authenticate for the Holder at the expense of the Company
a new Note equal in principal amount at maturity to the
unredeemed or unpurchased portion of the Note surrendered. 

Section 3.07.   Optional Redemption.

       Except as provided in the next paragraph, the
Notes shall not be redeemable at the Company's option prior to
April 1, 2001.  Thereafter, the Notes shall be subject to
redemption at the option of the Company, in whole or in part,
upon not less than 30 nor more than 60 days' notice, at the
redemption prices (expressed as percentages of principal
amount at maturity) set forth below plus accrued and unpaid
interest thereon to the applicable redemption date, if redeemed
during the twelve-month period beginning on April 1 of the
years indicated below:

    Year      Percentage

    2001      105.500%
    2002      103.667%
    2003      101.833%
    2004 and thereafter. . . . . . . . . . . .  100.000%

       Notwithstanding the foregoing, at any time prior to
April 1, 1999, the Company may on one or more occasions
redeem up to $42.0 million in aggregate principal amount at
maturity of Notes with the net proceeds of one or more public
offerings of common stock of the Company at a redemption
price equal to 110% of the principal amount at maturity
thereof, plus accrued and unpaid interest thereon to the
applicable redemption date; provided that at least $78.0 million
in aggregate principal amount at maturity of the Notes remain
outstanding immediately after the occurrence of each such
redemption; and provided, further, that any such redemption
must occur within 90 days of the date of the closing of such
public offering.

Section 3.08.   Mandatory Redemption.

       Except as set forth below under Section 3.09,
Section 4.10 and Section 4.15 hereof, the Company shall not be
required to make mandatory redemption or sinking fund
payments with respect to the Notes.

Section 3.09.   Asset Sale Offers.

       In the event that the Company shall be required to
commence an Asset Sale Offer pursuant to Section 4.10 hereof,
it shall follow the procedures specified below:

       The Asset Sale Offer shall remain open for 20
Business Days after the Commencement Date relating to such
Asset Sale Offer, except to the extent required to be extended
by applicable law (as so extended, the "Offer Period").  No
later than five Business Days after the termination of the Offer
Period (the "Purchase Date"), the Company shall purchase the
principal amount at maturity (the "Offer Amount") of Notes
required to be purchased in such Asset Sale Offer pursuant to
Sections 3.02 and 4.10 hereof or, if less than the Offer Amount
has been tendered, all Notes tendered in response to the Asset
Sale Offer.

       If the Purchase Date is on or after an interest
payment record date and on or before the related interest
payment date, any interest accrued to such Purchase Date shall
be paid to the Person in whose name a Note is registered at the
close of business on such record date, and no additional interest
shall be payable to Holders who tender Notes pursuant to the
Asset Sale Offer.

       On the Commencement Date of any Asset Sale
Offer, the Company shall send or cause to be sent, by first
class mail, postage prepaid, a notice to each of the Holders,
with a copy to the Trustee.  Such notice, which shall govern
the terms of the Asset Sale Offer, shall contain all instructions
and materials necessary to enable the Holders to tender Notes
pursuant to the Asset Sale Offer and shall state:

       (1)   that the Asset Sale Offer is being made
             pursuant to this Section 3.09 and Section 4.10
             hereof and the length of time the Asset Sale
             Offer shall remain open;

       (2)   the Offer Amount, the purchase price and the
             Purchase Date;

       (3)   that any Note not tendered or accepted for
             payment shall continue to accrue interest;

       (4)   that, unless the Company defaults in the
             payment of the purchase price, any Note
             accepted for payment pursuant to the Asset
             Sale Offer shall cease to accrue interest after
             the Purchase Date;

       (5)   that Holders electing to have a Note
             purchased pursuant to any Asset Sale Offer
             shall be required to surrender the Note, with
             the form entitled "Option of Holder to Elect
             Purchase" on the reverse of the Note
             completed, to the Company, a depositary, if
             appointed by the Company, or a Paying
             Agent at the address specified in the notice
             prior to the close of business at least one
             Business Day preceding the Purchase Date;

       (6)   that Holders shall be entitled to withdraw
             their election if the Company, depositary or
             Paying Agent, as the case may be, receives,
             not later than the close of business on the last
             day of the Offer Period, a telegram, telex,
             facsimile transmission or letter setting forth
             the name of the Holder, the principal amount
             at maturity of the Note the Holder delivered
             for purchase and a statement that such Holder
             is withdrawing his election to have the Note
             purchased;

       (7)   that, if the aggregate principal amount at
             maturity of Notes surrendered by Holders
             exceeds the Offer Amount, the Trustee shall
             select the Notes to be purchased on a pro rata
             basis (with such adjustments as may be
             deemed appropriate by the Company so that
             only Notes in denominations of $1,000, or
             integral multiples thereof, shall be
             purchased); and 

       (8)   that Holders whose Notes were purchased
             only in part shall be issued new Notes equal
             in principal amount at maturity to the
             unpurchased portion of the Notes
             surrendered.

       On or before 10:00 a.m. (New York City time) on
each Purchase Date, the Company shall irrevocably deposit
with the Trustee or Paying Agent in immediately available
funds the aggregate purchase price with respect to a principal
amount at maturity of Notes equal to the Offer Amount,
together with accrued interest thereon, if any, to be held for
payment in accordance with the terms of this Section 3.09.  On
the Purchase Date, the Company shall, to the extent lawful, (i)
accept for payment, pursuant to Section 3.02 hereof, an
aggregate principal amount at maturity equal to the Offer
Amount of Notes tendered pursuant to the Asset Sale Offer, or
if less than the Offer Amount has been tendered, all Notes or
portions thereof tendered, (ii) deliver or cause the Paying
Agent or depositary, as the case may be, to deliver to the
Trustee Notes so accepted and (iii) deliver to the Trustee an
Officers' Certificate stating that such Notes or portions thereof
were accepted for payment by the Company in accordance with
the terms of this Section 3.09.  The Company, the depositary
or Paying Agent, as the case may be, shall promptly (but in any
case not later than three Business Days after the Purchase Date)
mail or deliver to each tendering Holder an amount equal to the
Purchase Price with respect to the Notes tendered by such
Holder and accepted by the Company for purchase, and the
Company shall promptly issue a new Note, and the Trustee
shall authenticate and mail or deliver such new Note, to such
Holder, equal in principal amount at maturity to any
unpurchased portion of such Holder's Notes surrendered.  Any
Note not accepted in the Asset Sale Offer shall be promptly
mailed or delivered by the Company to the Holder thereof. 
The Company shall publicly announce in a newspaper of
general circulation or in a press release provided to a nationally
recognized financial wire service the results of the Asset Sale
Offer on the Purchase Date.

       Other than as specifically provided in this Section
3.09, each purchase pursuant to this Section 3.09 shall be made
pursuant to the provisions of Sections 3.01, 3.02, 3.05 and
3.06 hereof.

                  COVENANTS

Section 4.01.   Payment of Notes.

       The Company shall pay or cause to be paid the
principal of, premium, if any, and interest on the Notes on the
dates and in the manner provided in this Indenture and the
Notes.  Principal, premium, if any, and interest shall be
considered paid on the date due if the Paying Agent, if other
than the Company, holds as of 10:00 a.m. (New York City
time) on the due date money deposited by the Company in
immediately available funds and designated for and sufficient to
pay all principal, premium, if any, and interest then due.  Such
Paying Agent shall return to the Company, no later than five
days following the date of payment, any money that exceeds
such amount of principal, premium, if any, and interest paid on
the Notes.

       The Company shall pay interest (including post-
petition interest in any proceeding under any Bankruptcy Law)
on overdue principal at the rate equal to 1% per annum in
excess of the then applicable interest rate on the Notes to the
extent lawful; it shall pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on
overdue installments of interest (without regard to any
applicable grace period) at the same rate to the extent lawful.

Section 4.02.   Maintenance of Office or Agency.

       The Company shall maintain in the Borough of
Manhattan, the City of New York, an office or agency (which
may be an office of the Trustee or an affiliate of the Trustee,
Registrar or co-Registrar) where Notes may be surrendered for
registration of transfer or for exchange and where notices and
demands to or upon the Company in respect of the Notes and
this Indenture may be served.  The Company shall give prompt
written notice to the Trustee of the location, and any change in
the location, of such office or agency.  If at any time the
Company shall fail to maintain any such required office or
agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands
may be made or served at the Corporate Trust Office of the
Trustee.

       The Company may also from time to time
designate one or more other offices or agencies where the
Notes may be presented or surrendered for any or all such
purposes and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall
in any manner relieve the Company of its obligation to maintain
an office or agency in the Borough of Manhattan, the City of
New York for such purposes.  The Company shall give prompt
written notice to the Trustee of any such designation or
rescission and of any change in the location of any such other
office or agency.

       The Company hereby designates the Corporate
Trust Office of the Trustee as one such office or agency of the
Company in accordance with Section 2.03 hereof.

       So long as required to do so under the Exchange
Act, the Company shall file with the Commission and distribute
to the Holders of the Notes copies of the quarterly and annual
financial information required to be filed with the Commission
pursuant to the Exchange Act.  All such financial information
shall include consolidated financial statements (including
footnotes) prepared in accordance with GAAP.  Such annual
financial information shall also include an opinion thereon
expressed by an independent accounting firm of established
national reputation.  All such consolidated financial statements
shall be accompanied by a "Management's Discussion and
Analysis of Financial Condition and Results of Operations" that
describes the financial condition and results of operations of the
Company and its Restricted Subsidiaries.  In addition, whether

such a filing) and furnish to the Holders of Notes (i) all
quarterly and annual financial information that would be
required to be contained in a filing with the Commission on
Forms 10-Q and 10-K, if the Company were required to file
such Forms, including a "Management's Discussion and
Analysis of Financial Condition and Results of Operations" that
describes the financial condition and results of operations of the
Company and its Restricted Subsidiaries and, with respect to
the annual information only, a report thereon by the
Company's certified independent accountants and (ii) all
current reports that would be required to be filed with the
Commission on Form 8-K if the Company were required to file
such reports.  The Company also agrees to make such
information available to securities analysts and prospective
investors upon request.

       The financial information to be distributed to
Holders of Notes shall be filed with the Trustee and mailed to
the Holders at their addresses appearing in the register of Notes
maintained by the Registrar, within 120 days after the end of
the Company's fiscal years and within 60 days after the end of
each of the first three quarters of each such fiscal year.

within 120 days after the end of each fiscal year, a certificate
which need not comply with Section 10.05 from the principal
executive, financial or accounting officer of the Company as to
his or her knowledge of the Company's compliance with all
conditions and covenants under the Indenture (such compliance
to be determined without regard to any period of grace or
requirement of notice provided under the Indenture).

       (b)   So long as not contrary to the then current
recommendations of the American Institute of Certified Public
Accountants, in connection with the year-end financial
statements delivered pursuant to Section 4.03 hereof, the
Company shall use its best efforts to deliver a written statement
of the Company's independent public accountants (who shall be
a firm of established national reputation reasonably satisfactory
to the Trustee) that in making the examination necessary for
certification of such financial statements, nothing has come to
their attention that would lead them to believe that the
Company has violated any provisions of this Article 4, Section
5.01 hereof or, if any such violation has occurred, specifying
the nature and period of existence thereof, it being understood
that such accountants shall not be liable directly or indirectly to
any Person for any failure to obtain knowledge of any such
violation.  In the event that such written statement of the
Company's independent public accountants cannot be obtained,
the Company shall deliver an Officer's Certificate certifying
that it has used its best efforts to obtain such statement but was
unable to do so.

       (c)   The Company shall, so long as any of the
Notes are outstanding, deliver to the Trustee, forthwith upon
any Officer becoming aware of any Default or Event of
Default, an Officers' Certificate specifying such Default or
Event of Default and what action the Company is taking or
proposes to take with respect thereto.

Section 4.05.   Taxes.

       The Company shall pay, and shall cause each of its
Subsidiaries to pay, prior to delinquency, all material taxes,

do so) shall not at any time insist upon, plead, or in any
manner whatsoever claim or take the benefit or advantage of,
any stay, extension or usury law wherever enacted, now or at
any time hereafter in force, that may affect the covenants or the
performance of this Indenture; and the Company (to the extent
that it may lawfully do so) hereby expressly waives all benefit
or advantage of any such law, and covenants that it shall not,
by resort to any such law, hinder, delay or impede the
execution of any power herein granted to the Trustee, but shall
suffer and permit the execution of every such power as though
no such law has been enacted.

Section 4.07.   Restricted Payments.

       The Company shall not, and shall not permit any
of its Restricted Subsidiaries to, directly or indirectly:  (i)
declare or pay any dividend or make any distribution on
account of the Company's or any of its Subsidiaries' Equity
Interests (including, without limitation, any payment in
connection with any merger or consolidation involving the
Company), except in each case for dividends or distributions
payable in Equity Interests (other than Disqualified Stock) of
the Company or dividends or distributions payable to the
Company or any Restricted Subsidiary of the Company;

any Equity Interests of the Company or any Affiliate of the

Company or any Restricted Subsidiary of the Company); (iii)
voluntarily purchase, redeem, defease or otherwise acquire or
retire for value prior to any scheduled maturity date, scheduled
repayment date (except for mandatory repurchases or
redemptions upon the occurrence of certain specified events) or
sinking fund payment date any Indebtedness that is
subordinated to the Notes; or (iv) make any Restricted
Investment (all such payments and other actions set forth in
clauses (i) through (iv) above being collectively referred to as
"Restricted Payments"), unless:

       (a)   no Default or Event of Default shall have
    occurred and be continuing or would occur as a
    consequence thereof; 

       (b)   the Company would, at the time of such
    Restricted Payment and after giving pro forma effect
    thereto as if such Restricted Payment had been made at
    the beginning of the applicable four-quarter period,
    have been permitted to incur at least $1.00 of additional
    Indebtedness pursuant to the Fixed Charge Coverage
    Ratio test set forth in the first paragraph of Section 4.14
    hereof;

       (c)   such Restricted Payment, together with the
    aggregate of all other Restricted Payments made by the
    Company and its Restricted Subsidiaries after the date
    of the Indenture (excluding Restricted Payments
    permitted by clauses (b)(1) and (b)(2) in the next
    succeeding paragraph), is less than the sum of (i) 50%
    of the Consolidated Net Income of the Company for the
    period (taken as one accounting period) from the
    beginning of the first fiscal quarter commencing after
    the date of the Indenture to the end of the Company's
    most recently ended fiscal quarter for which internal
    financial statements are available at the time of such
    Restricted Payment (or, if such Consolidated Net
    Income for such period is a deficit, less 100% of such
    deficit), plus (ii) 100% of any cash dividends received
    by the Company or a Restricted Subsidiary of the
    Company after the date of the Indenture from any
    Unrestricted Subsidiary of the Company, plus (iii)
    100% of the aggregate net cash proceeds and the fair
    market value of any property that is converted into cash
    within 180 days after receipt thereof, in each case, that
    is received by the Company as a capital contribution or
    from the issue or sale since the date of the Indenture of
    Equity Interests of the Company or of debt securities of
    the Company that have been converted into such Equity
    Interests (other than Equity Interests (or convertible
    debt securities) sold to a Subsidiary of the Company
    and other than Disqualified Stock or debt securities that
    have been converted into Disqualified Stock), provided,
    however,  that in no event shall any net proceeds or
    property utilized to redeem, repurchase, retire or
    acquire Equity Interests or subordinated Indebtedness
    pursuant to clause (b)(1) or (b)(2) of the following
    paragraph be included for purposes of this clause (iii),
    plus (iv) to the extent that any Restricted Investment
    that was made after the date of the Indenture is sold for
    cash or otherwise liquidated or repaid for cash, the
    lesser of (A) the cash return of capital with respect to
    such Restricted Investment (less the cost of disposition,
    if any) and (B) the initial amount of such Restricted
    Investment.  For purposes of clause (iii) of this
    paragraph (c) the fair market value of any property
    received as a capital contribution or from the issue or
    sale of Equity Interests or convertible debt securities
    shall be the amount of cash received upon conversion
    of such property.

In determining the aggregate amount expended for Restricted
Payments for purposes of clause (c) of this paragraph, 100% of
the amounts expended pursuant to clauses (a) of the next
succeeding paragraph (but only to the extent the declaration
thereof has not already decreased amounts available for
Restricted Payments pursuant to clause (c) of this paragraph),
(b)(3), (b)(4), (b)(5) and (b)(6) of the next succeeding
paragraph shall be included.   

       The foregoing provisions will not prohibit (a) the
payment of any dividend within 60 days after the date of
declaration thereof if at said date of declaration such payment
would have complied with the provisions of the Indenture or
(b) if no Default or Event of Default shall have occurred or be
continuing immediately following such Restricted Payment, (1)
the redemption, repurchase, retirement or other acquisition of
any Equity Interests of the Company in exchange for, or out of
the proceeds of, the substantially concurrent sale (other than to
a Subsidiary of the Company) of other Equity Interests of the

amount of any such net cash proceeds that are utilized for any
such redemption, repurchase, retirement or other acquisition
shall be excluded from clause (c) (iii) of the preceding
paragraph; (2) the defeasance, redemption or repurchase of
subordinated Indebtedness with the net cash proceeds from an
incurrence of Permitted Refinancing Indebtedness or the
substantially concurrent sale (other than to a Subsidiary of the
Company) of Equity Interests of the Company (other than
Disqualified Stock); provided that the amount of any such net
cash proceeds that are utilized for any such redemption,
repurchase, retirement or other acquisition shall be excluded
from clause (c)(iii) of the preceding paragraph; (3) payment of
cash dividends on shares of the Company's Non-Voting
Preferred Stock outstanding on the date of the Indenture;
provided that the aggregate amount of all such dividends
following the date of the Indenture shall not exceed $1.5
million; (4) loans or advances to employees made in the
ordinary course of business not exceeding $2.0 million
outstanding at any one time; (5) payment of dividends by any

Subsidiaries own at least 80% of the Equity Interests of such
Restricted Subsidiary; and (6) other Restricted Payments in an
aggregate amount since the date hereof not to exceed $2.0

       Not later than the date of making any Restricted
Payment, the Company shall deliver to the Trustee an Officer's
Certificate stating that such Restricted Payment is permitted and
setting forth the basis upon which the calculations required by
this covenant were computed, which calculations may be based
upon the Company's latest available financial statements.

Section 4.08.   Dividend and Other Payment Restrictions
                Affecting Subsidiaries.

       The Company shall not, and shall not permit any
of its Restricted Subsidiaries to, directly or indirectly, create or
otherwise cause or suffer to exist or become effective any
consensual encumbrance or restriction on the ability of any
Restricted Subsidiary to (i)(A) pay dividends or make any other
distributions to the Company or any of its Restricted
Subsidiaries (1) on its Capital Stock or (2) with respect to any
other interest or participation in, or measured by, its profits, or
(B) pay any Indebtedness owed to the Company or any of its
Restricted Subsidiaries, (ii) make loans or advances to the
Company or any of its Restricted Subsidiaries or (iii) transfer
any of its properties or assets to the Company or any of its
Restricted Subsidiaries, except for such encumbrances or
restrictions existing under or by reason of (A) Existing
Indebtedness as in effect on the date hereof, (B) the New Credit
Facility as in effect on the date of the Indenture and any
amendments, modifications, restatements, renewals, increases,
supplements, refundings, replacements or refinancings thereof,
provided that such amendments, modifications, restatements,
renewals, increases, supplements, refundings, replacement or
refinancings are no more restrictive with respect to such
dividend and other payment restrictions than those contained in
the New Credit Facility as in effect on the date of the
Indenture, (C) the Indenture and the Notes, (D) applicable law,
(E) any agreement or instrument binding on a Person acquired
by the Company or any of its Restricted Subsidiaries, or on the
property or assets of such Person, as in effect at the time of
such acquisition (except to the extent such encumbrance or
restriction was incurred in connection with or in contemplation
of such acquisition), which encumbrance or restriction is not
applicable to any Person, or the properties or assets of any
Person, other than the Person, or the property or assets of the
Person, so acquired, (F) customary non-assignment provisions
in leases entered into in the ordinary course of business and
consistent with past practices, (G) purchase money obligations
for property acquired in the ordinary course of business that
impose restrictions of the nature described in this clause (iii) on
the property so acquired or (H) Permitted Refinancing
Indebtedness, provided that the restrictions contained in the
agreements governing such Permitted Refinancing Indebtedness
are no more restrictive than those contained in the agreements
governing the Indebtedness being refinanced.

Section 4.09.   Line of Business.

       The Company shall not, and shall not permit any
Restricted Subsidiary to, engage in any business other than a
Permitted Business.

Section 4.10.   Asset Sales.

       The Company shall not, and shall not permit any
of its Restricted Subsidiaries to, engage in an Asset Sale unless
(i) the Company (or the Restricted Subsidiary, as the case may
be) receives consideration at the time of such Asset Sale at least
equal to the fair market value (evidenced by a resolution of the
Board of Directors set forth in an Officer's Certificate delivered
to the Trustee) of the assets or Equity Interests issued or sold or
otherwise disposed of and (ii) at least 75% of the consideration
therefor received by the Company or such Restricted
Subsidiary is in the form of cash; provided that (x) the amount
of (1) any liabilities (as shown on the Company's or such
Restricted Subsidiary's most recent balance sheet or in the
notes thereto) of the Company or any Restricted Subsidiary
(other than liabilities that are by their terms subordinated to the
Notes or any guarantee thereof) that are assumed by the
transferee of any such assets and (2) any notes or other
obligations received by the Company or any such Restricted
Subsidiary from such transferee that are immediately converted
by the Company or such Restricted Subsidiary into cash (to the
extent of the cash received) shall be deemed to be cash for
purposes of this provision, (y) if the Company or any
Restricted Subsidiary has acquired a Person engaged in a
Permitted Business (a "Prior Acquisition") within 365 days
prior to any Asset Sale involving assets acquired in the Prior
Acquisition (the "Subsequent Asset Sale"), then, subject to the
following proviso, all or a portion of the consideration received
by the Company or the applicable Restricted Subsidiary in
connection with such Subsequent Asset Sale need not be in the
form of cash; provided, however, that (1) such non-cash
consideration may not exceed 20% of the aggregate
consideration paid by the Company or such Restricted
Subsidiary in the Prior Acquisition and (2) the aggregate fair
market value of all such non-cash consideration received by the
Company and its Restricted Subsidiaries since the date of the
Indenture shall not exceed $20 million, and (z) any sale by the
Company or any Restricted Subsidiary of Equity Interests of
any Unrestricted Subsidiary of the Company shall not be
subject to the requirement set forth in clause (ii) of this
paragraph.

       Within 270 days after the receipt of any Net
Proceeds from an Asset Sale, the Company may apply such Net
Proceeds, at its option, (a) to permanently reduce Senior
Revolving Debt (and to correspondingly reduce Commitments
with respect thereto, unless such revolving credit debt could be
incurred under the first paragraph of Section 4.14 hereof) or
(b) to an investment in a Permitted Business, or the making of a
capital expenditure or the acquisition of other long-
term/tangible assets or other assets that would be included as
property, plant and equipment on a balance sheet in accordance
with GAAP, in each case, utilized in a Permitted Business. 
Pending the final application of any such Net Proceeds, the
Company may temporarily reduce Senior Revolving Debt or
otherwise invest such Net Proceeds in any manner that is not
prohibited herein.  Any Net Proceeds from Asset Sales that are
not applied or invested as provided in the first sentence of this
paragraph will be deemed to constitute "Excess Proceeds." 
When the aggregate amount of Excess Proceeds exceeds $5.0
million, the Company will be required to make an offer to all
Holders of Notes (an "Asset Sale Offer") to purchase the
maximum principal amount at maturity of Notes that may be
purchased out of the Excess Proceeds, at an offer price in cash
in an amount equal to 100% of the principal amount at maturity
thereof plus accrued and unpaid interest thereon to the date of
purchase, in accordance with the procedures set forth in
Section 3.09 hereof.  To the extent that the aggregate amount
of Notes tendered pursuant to an Asset Sale Offer is less than
the Excess Proceeds, any remaining Excess Proceeds upon
completion of such offer to purchase shall cease to be Excess
Proceeds and may be used by the Company for general
corporate purposes.  If the aggregate principal amount at
maturity of Notes surrendered by Holders thereof exceeds the
amount of Excess Proceeds, the Trustee shall select the Notes
to be purchased on a pro rata basis.  

       An Asset Sale Offer shall be made pursuant to the
provisions of Section 3.09 hereof.  No later than the date which
is five (5) Business Days after the date on which the aggregate
amount of Excess Proceeds exceeds $5.0 million, the Company
shall notify the Trustee of such Asset Sale Offer in accordance
with Section 3.09 hereof and commence or cause to be
commenced the Asset Sale Offer on a date no later than fifteen
(15) Business Days after such notice (the "Commencement
Date).

       The Asset Sale Offer shall be made by the
Company in compliance with all applicable laws, including,
without limitation, Rule 14e-1 under the Exchange Act and the
rules thereunder, to the extent applicable, and all other
applicable federal and state securities laws.

Section 4.11.   Transactions with Affiliates.

             The Company shall not, and shall not
permit any of its Restricted Subsidiaries to, sell, lease, transfer
or otherwise dispose of any of its properties or assets to, or
purchase any property or assets from, or enter into or make
any contract, agreement, loan, advance or guarantee with, or
for the benefit of, any Affiliate (each of the foregoing, an
"Affiliate Transaction") unless (i) such Affiliate Transaction is
on terms that are no less favorable to the Company or the
relevant Restricted Subsidiary than those that would have been
obtained in a comparable transaction by the Company or such
Restricted Subsidiary with an unrelated Person and (ii) the
Company delivers to the Trustee (a) with respect to any
Affiliate Transaction involving aggregate consideration in
excess of $1.0 million, an Officer's Certificate setting forth a
resolution of the Board of Directors to the effect that such
Affiliate Transaction complies with clause (i) above and that
such Affiliate Transaction has been approved by a majority of
the disinterested members of the Board of Directors and (b)
with respect to any Affiliate Transaction involving aggregate
consideration in excess of $5.0 million, an opinion issued by an
investment banking firm of national standing as to the fairness
to the Company or such Restricted Subsidiary of such Affiliate
Transaction from a financial point of view; provided that the
following shall not be deemed Affiliate Transactions: (x)
reasonable and customary payments and other benefits
(including indemnification) provided to directors for service on
the Board of Directors of the Company or any Restricted
Subsidiary, including the reimbursement or advancement of
out-of-pocket expenses and directors' and officers' liability
insurance; (y) transactions between or among the Company
and/or its Restricted Subsidiaries; and (z) Restricted Payments
permitted by clauses (a), (b)(3) and (b)(5) of the second
paragraph of Section 4.07 hereof.

Section 4.12.   Liens.

       The Company shall not, and shall not permit any
of its Restricted Subsidiaries to, directly or indirectly, create,
incur, assume or suffer to exist any Lien, except Permitted
Liens, on any asset now owned or hereafter acquired or any
income or profits therefrom or assign or convey any right to
receive income therefrom to secure any Indebtedness unless (i)
such Indebtedness is pari passu in right of payment with the
Notes and (ii) all Obligations with respect to the Notes are
secured on an equal and ratable basis with the Indebtedness so
secured.  

Section 4.13.   Sale and Lease Back Transactions.

       The Company shall not, and shall not permit any
of its Restricted Subsidiaries to, enter into any sale and
leaseback transaction; provided that the Company or any of its
Restricted Subsidiaries may enter into a sale and leaseback
transaction if (i) the Company or such Restricted Subsidiary
could have incurred Indebtedness in an amount equal to the
Attributable Debt relating to such sale and leaseback transaction
pursuant to the applicable Fixed Charge Coverage Ratio test set
forth in the first paragraph of Section 4.14 hereof, (ii) the gross
cash proceeds of such sale and leaseback transaction are at least
equal to the fair market value (as determined in good faith by
the Board of Directors and set forth in an Officer's Certificate
delivered to the Trustee) of the property that is the subject of
such sale and leaseback transaction and (iii) the transfer of
assets in such sale and leaseback transaction is permitted by,
and the Company or such Restricted Subsidiary applies the
proceeds of such transaction in compliance with Section 4.10
hereof.

Section 4.14.   Incurrence of Indebtedness and Issuance
                of Preferred Stock.

       The Company shall not, and shall not permit any
of its Restricted Subsidiaries to, directly or indirectly, create,
incur, issue, assume, guarantee or otherwise become directly or
indirectly liable, contingently or otherwise, with respect to
(collectively, "incur") any Indebtedness (including Acquired
Debt) and that the Company will not issue any Disqualified
Stock and will not permit any of its Restricted Subsidiaries to
issue any shares of preferred stock; provided, however, that (i)
the Company may incur Indebtedness (including Acquired
Debt) or issue shares of Disqualified Stock if (A) the Fixed
Charge Coverage Ratio for the Company's most recently ended
four full fiscal quarters for which internal financial statements
are available immediately preceding the date on which such
additional Indebtedness is incurred or such Disqualified Stock
is issued would have been at least 2.0 to 1 determined on a pro
forma basis after giving effect to the incurrence of such
Indebtedness or issuance of Disqualified Stock (including a pro
forma application of the net proceeds therefrom) as if the
additional Indebtedness or Disqualified Stock had been incurred
or issued, as applicable, at the beginning of such four-quarter
period and (B) any such Indebtedness that is subordinated in
right of payment to the Notes provides for no sinking fund
payments, and does not mature, prior to October 1, 2006;
provided, however, that the provisions of this clause (B) shall
not apply to up to $10 million aggregate principal amount of
subordinated Indebtedness of the Company outstanding at any
time that is incurred to fund all or a portion of the purchase
price of the acquisition of all of the Capital Stock or assets of
any entity engaged in a Permitted Business and (ii) any
Restricted Subsidiary may incur Acquired Debt and
Attributable Debt in respect of permitted sale and leaseback
transactions in an aggregate amount not to exceed $5.0 million
outstanding at any time if the Fixed Charge Coverage Ratio for
the Company's most recently ended four fiscal quarters for
which internal financial statements are available immediately
preceding the date on which the Acquired Debt or Attributable
Debt is incurred would have been at least 2.0 to 1 determined
on a pro forma basis after giving effect to the incurrence of
such Acquired Debt or Attributable Debt as if it had been
incurred at the beginning of such four-quarter period.

       The foregoing provisions will not apply to:

    (i)   the incurrence by the Company of Senior
Revolving Debt for working capital purposes (with letters of
credit thereunder being deemed to have a principal amount
equal to the maximum potential liability of the Company
thereunder) in an aggregate principal amount not to exceed the
Borrowing Base;

      (ii)   the incurrence by the Company of
Indebtedness represented by the Notes;

     (iii)   the incurrence by the Company or any of its
Restricted Subsidiaries of Indebtedness represented by Capital
Lease Obligations or Purchase Money Obligations, in each case
incurred for the purpose of financing all or any part of the
purchase price or cost of construction or improvement of
property or purchase of equipment used in the business of the
Company or such Restricted Subsidiary, in an aggregate
principal amount not to exceed $5 million at any time
outstanding;

      (iv)   the incurrence by the Company or any of its
Restricted Subsidiaries of Permitted Refinancing Indebtedness
in exchange for, or the net proceeds of which are used to
extend, refinance, renew, replace, defease or refund (including
the cost thereof), Existing Indebtedness or Indebtedness that
was permitted hereby to be incurred (other than Indebtedness
incurred pursuant to clause (xi) of this paragraph); provided,
however, that no Restricted Subsidiary shall incur Permitted
Refinancing Indebtedness in respect of Indebtedness of the
Company;

    (v)   the incurrence by the Company or any of its
Wholly Owned Restricted Subsidiaries of intercompany
Indebtedness between or among the Company and any of its
Wholly Owned Restricted Subsidiaries; provided, however, that
(i) any subsequent issuance or transfer (other than for security
purposes) of Equity Interests that results in any such
Indebtedness being held by a Person other than a Wholly
Owned Restricted Subsidiary and (ii) any sale or other transfer
(other than for security purposes) of any such Indebtedness to a
Person that is neither the Company nor a Wholly Owned
Restricted Subsidiary of the Company shall be deemed, in each
case, to constitute an incurrence of such Indebtedness by the
Company or such Restricted Subsidiary, as the case may be;

      (vi)   the incurrence by the Company or any of its
Restricted Subsidiaries of Hedging Obligations that are incurred
for the purpose of fixing or hedging interest rate risk with
respect to any floating rate Indebtedness that is permitted by the
terms of the Indenture to be outstanding;

     (vii)   the incurrence by the Company or any of its
Restricted Subsidiaries of Indebtedness in respect of bid,
performance or advance payment bonds, bankers' acceptances
and surety or appeal bonds provided in the ordinary course of
business;

    (viii)   the incurrence by the Company of
Indebtedness under a Guarantee of any Indebtedness of a
Restricted Subsidiary permitted to be incurred pursuant to the
Indenture;

      (ix)   the incurrence by the Company of
Indebtedness (in addition to Indebtedness permitted by any
other clause of this paragraph) in an aggregate principal amount
at any time outstanding not to exceed $5.0 million;

    (x)   the incurrence by the Company of
Indebtedness under a Guarantee of any Indebtedness of an
employee of the Company or any of its Restricted Subsidiaries
incurred by such employee in connection with his or her
relocation for work purposes in a principal amount not to
exceed $1.0 million outstanding at any time, and any
refinancing of such employee Indebtedness; provided, however,
that the principal amount of such refinanced Indebtedness shall
not exceed the principal amount of the Indebtedness so
refinanced; and

    (xi)     the incurrence by the Company of up to $15.0
million principal amount of Permitted Acquisition Indebtedness
after the date hereof.
       
       For purposes of determining compliance with this
covenant from time to time, (i) in the event that an item of
Indebtedness meets the criteria of more than one type of
Indebtedness permitted by this covenant, the Company in its
sole discretion will for purposes of this covenant, classify such
item of Indebtedness as only one such type and will only be
required to include the amount of such Indebtedness in such
one type; and (ii) the amount of Indebtedness issued at a price
which is less than the principal amount thereof shall be equal to
the amount of liability in respect thereto determined in
accordance with GAAP.

Section 4.15.   Offer to Purchase Upon Change of
                Control.

       Upon the occurrence of a Change of Control, each
Holder of Notes will have the right to require the Company to
repurchase all or any part of such Holder's Notes pursuant to
the offer described below (the "Change of Control Offer") at an
offer price in cash equal to 101% of the aggregate principal
amount at maturity thereof plus accrued and unpaid interest
thereon to the date of purchase (the "Change of Control
Payment").

       Within thirty (30) calendar days following any
Change of Control, the Company shall mail a notice to each
Holder stating: 

       (1)   that the Change of Control Offer is being

             Notes properly tendered will be accepted for
             payment; 

       (2)   the purchase price and the purchase date,
             which will be no earlier than 30 days nor later
             than 60 days from the date such notice is
             mailed (the "Change of Control Payment
             Date");

       (3)   that any Note not properly tendered will
             continue to accrue interest; 

       (4)   that, unless the Company defaults in the
             payment of the Change of Control Payment,
             all Notes accepted for payment pursuant to
             the Change of Control Offer will cease to
             accrue interest after the Change of Control
             Payment Date; 

       (5)   that Holders electing to have any Notes
             purchased pursuant to a Change of Control
             Offer will be required to surrender the Notes,
             with the form entitled "Option of Holder to
             Elect Purchase" on the reverse of the Notes
             completed, or transfer by book-entry, to the
             Paying Agent at the address specified in the
             notice prior to the close of business at least
             one  Business Day preceding the Change of
             Control Payment Date; 

       (6)   that Holders will be entitled to withdraw their
             election if the Paying Agent receives, not
             later than one Business Day prior to the close
             of business on the Change of Control
             Payment Date, a telegram, telex, facsimile
             transmission or letter setting forth the name of
             the Holder, the principal amount at maturity
             of Notes delivered for purchase, and a
             statement that such Holder is withdrawing his
             election to have such Notes purchased;

       (7)   that Holders whose Notes are being purchased
             only in part will be issued new Notes equal in
             principal amount at maturity to the
             unpurchased portion of the Notes surrendered
             (or transferred by book-entry), which
             unpurchased portion must be equal to $1,000
             in principal amount at maturity or an integral
             multiple thereof; and

       (8)   the circumstances and material facts regarding
             such Change of Control (including, but not
             limited to, information with respect to pro
             forma and historical financial information
             after giving effect to such Change of Control,
             and information regarding the Person or
             Persons acquiring control).      

       On the Change of Control Payment Date, the
Company will, to the extent lawful, (1) accept for payment all
Notes or portions thereof properly tendered pursuant to the
Change of Control Offer, (2) deposit with the Paying Agent an
amount equal to the Change of Control Payment in respect of
all Notes or portions thereof so tendered and (3) deliver or
cause to be delivered to the Trustee the Notes so accepted
together with an Officers' Certificate stating the aggregate
principal amount at maturity of Notes or portions thereof
tendered to the Company.  The Paying Agent will promptly
mail to each Holder of Notes so tendered the Change of
Control Payment for such Notes, and the Trustee will promptly
authenticate and mail (or cause to be transferred by book entry)
to each Holder a new Note equal in principal amount at
maturity to any unpurchased portion of the Notes surrendered,
if any; provided that each such new Note will be in a principal
amount at maturity of $1,000 or an integral multiple thereof.
The Company will publicly announce the results of the Change
of Control Offer on or as soon as practicable after the Change
of Control Payment Date.

       The Company shall comply with the requirements
of Rule 14e-1 under the Exchange Act and any other securities
laws and regulations thereunder to the extent such laws and
regulations are applicable in connection with the repurchase of
the Notes as a result of a Change of Control.


Section 4.16.   Corporate Existence.

       Subject to Section 4.15 and Article 5 hereof, as the
case may be, the Company shall do or cause to be done all
things necessary to preserve and keep in full force and effect (i)
its corporate existence, and the corporate, partnership or other
existence of each of its Restricted Subsidiaries, in accordance
with the respective organizational documents (as the same may
be amended from time to time) of the Company or any such
Restricted Subsidiary, as the case may be, and (ii) the rights
(charter and statutory), licenses and franchises of the Company
and its Restricted Subsidiaries; provided, however, that the
Company shall not be required to preserve any such right,
license or franchise, or the corporate, partnership or other
existence of any of its Restricted Subsidiaries, if the Board of
Directors of the Company shall determine that the preservation
thereof is no longer desirable in the conduct of the business of
the Company and its Restricted Subsidiaries, taken as a whole,
and that the loss thereof is not adverse in any material respect
to the Holders of the Notes.

merger (if other than the Company) or to which such sale,
assignment, transfer, lease, conveyance or other disposition
shall have been made is a corporation organized or existing
under the laws of the United States, any state thereof or the

conveyance or other disposition shall have been made assumes
all the obligations of the Company under the Notes and the
Indenture pursuant to a supplemental indenture in a form
reasonably satisfactory to the Trustee; (iii) immediately after
such transaction no Default or Event of Default exists; and (iv)

       Upon any consolidation or merger, or any sale,

its Restricted Subsidiaries shall only be included for periods
subsequent to the effective time of such merger, consolidation,
combination or transfer of assets; and provided, however, in the
case of any sale, assignment, transfer, lease, conveyance or
other disposition of less than all of the assets of the Company,
the Company shall not be released or discharged from the
obligation to pay the principal of or interest on the Notes.


                 ARTICLE 6

Section 6.01.   Events of Default.

       An "Event of Default" occurs if:

    interest on the Notes when the same becomes due and
    payable and such default continues for a period of
    thirty (30) days;

          (b)   the Company defaults in the payment of
    principal of or premium, if any, on the Notes when the
    same becomes due and payable at maturity, upon
    redemption or otherwise;

          (c)   the Company fails to comply with the

    aggregate principal amount at maturity of the then
    outstanding Notes;

          (e)   a default occurs under any mortgage,
    indenture or instrument under which there may be
    issued or by which there may be secured or evidenced
    any Indebtedness for money borrowed by the Company
    or any of its Restricted Subsidiaries (or the payment of
    which is guaranteed by the Company or any of its
    Restricted Subsidiaries) whether such Indebtedness or
    Guarantee now exists, or is created after the date of this
    Indenture, which default (i) is caused by a failure to
    pay when due the final scheduled principal installment
    on the stated maturity thereof prior to the expiration of
    the grace period set forth in the documents governing
    such Indebtedness (a "Payment Default") or (ii) results
    in the acceleration of such Indebtedness prior to its
    express maturity and, in each case, the principal
    amount of any such Indebtedness, together with the
    principal amount of any other such Indebtedness under
    which there has been a Payment Default or the maturity
    of which has been so accelerated, aggregates $5.0
    million or more;

          (f)   the Company or any of its Restricted
    Subsidiaries fails to pay final judgments aggregating in
    excess of $5.0 million if (A) any creditor has

    such final judgments or (B) such final judgments are
    not paid, discharged or stayed within 60 days of their
    entry; 

          (g)   the Company or any Restricted
    Subsidiary that is a Significant Subsidiary or group of
    Restricted Subsidiaries that, together, would constitute
    a Significant Subsidiary, pursuant to or within the
    meaning of any Bankruptcy Law:

             (i)    commences a voluntary case,

             (ii)   consents to the entry of an order for

             an order or decree under any Bankruptcy Law that:

             (i)    is for relief against the Company or
             any Restricted Subsidiary that is a
             Significant Subsidiary or group of
             Restricted Subsidiaries that, together,
             would constitute a Significant Subsidiary
             of the Company in an involuntary case in
             which it is the debtor,

             (ii)   appoints a Custodian of the
             Company or any Restricted Subsidiary
             that is a Significant Subsidiary or group
             of Restricted Subsidiaries that, together,
             would constitute a Significant Subsidiary
             of the Company or for all or substantially
             all of the property of the Company or
             any Restricted Subsidiary that is a
             Significant Subsidiary or group of
             Restricted Subsidiaries that, together,
             would constitute a Significant Subsidiary
             of the Company, or

             (iii)  orders the liquidation of the
             Company or any Restricted Subsidiary
             that is a Significant Subsidiary or group
             of Restricted Subsidiaries that, together,
             would constitute a Significant Subsidiary
             of the Company,

    and the order or decree remains unstayed and in effect
    for 60 consecutive days.

Section 6.02.   Acceleration and Payment of Premium.

       If an Event of Default (other than an Event of
Default with respect to the Company specified in clauses (g)
and (h) of Section 6.01 hereof) occurs and is continuing, the
Trustee or the Holders of at least 25% in principal amount at
maturity of the then outstanding Notes by written notice to the
Company (and the Trustee, if given by Holders) may declare
the unpaid principal of, premium, if any, and accrued and
unpaid interest on all the Notes to be due and payable and the
same (i) shall become immediately due and payable or (ii) if
there are any amounts outstanding under the New Credit
Facility, shall become due and payable upon the first to occur
of an acceleration under the New Credit Facility or five
business days after receipt by the Company and the
administrative agent under the New Credit Facility of notice of
such acceleration under the Indenture if such Event of Default
is continuing at such time.  If an Event of Default with respect
to the Company specified in clauses (g) or (h) of Section 6.01
hereof occurs, all outstanding Notes shall ipso facto become
and be immediately due and payable without any declaration or
other act on the part of the Trustee or any Holder.

       In the case of any Event of Default occurring by
reason of any willful action (or inaction) taken (or not taken) by
or on behalf of the Company or any of its Subsidiaries with the
intention of avoiding payment of the premium that the
Company would have had to pay if the Company then had
elected to redeem the Notes pursuant to Section 3.07 hereof, an
equivalent premium shall also become and be immediately due
and payable to the extent permitted by law upon the
acceleration of the Notes.  If an Event of Default occurs prior
to April 1, 2001 by reason of any willful action (or inaction)
taken (or not taken) by or on behalf of the Company or any of
its Subsidiaries with the intention of avoiding the prohibition on
redemption of the Notes prior to April 1, 2001, then the
premium payable for purposes of this paragraph for each of the
twelve month period beginning on April 1 of the years set forth
below shall be as set forth in the following table expressed as a
percentage of the amount that would otherwise be due but for
the provisions of this paragraph, plus accrued interest, if any,
to the date of payment:
          
          Year                   Percentage

          1996 . . . . . . . . . . 111.000%  
          1997 . . . . . . . . . . 109.900%  
          1998 . . . . . . . . . . 108.800%  
          1999 . . . . . . . . . . 107.700%  
          2000 . . . . . . . . . . 106.600%  

    The Holders of a majority in principal amount at
maturity of the then outstanding Notes by written notice to the
Trustee may rescind an acceleration and its consequences if the
rescission would not conflict with any judgment or decree and
if all existing Events of Default (except nonpayment of
principal or interest that has become due solely because of the
acceleration) have been cured or waived.  

Section 6.03.   Other Remedies.

       If an Event of Default occurs and is continuing,
the Trustee may pursue any available remedy to collect the
payment of principal, premium, if any, and interest on the
Notes or to enforce the performance of any provision of the
Notes or this Indenture. 

       The Trustee may maintain a proceeding even if it
does not possess any of the Notes or does not produce any of
them in the proceeding.  A delay or omission by the Trustee or
any Holder of a Note in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or
remedy or constitute a waiver of or acquiescence in the Event
of Default.  All remedies are cumulative to the extent permitted
by law. 

Section 6.04.   Waiver of Past Defaults.

       Holders of a majority in aggregate principal
amount at maturity of the Notes then outstanding, by notice to
the Trustee, may on behalf of the Holders of all of the Notes
waive any existing Default or Event of Default and its
consequences under this Indenture, except a continuing Default
or Event of Default in the payment of the principal of,
premium, if any, or interest on, the Notes.  Upon any such
waiver, such Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured
for every purpose of this Indenture; but no such waiver shall
extend to any subsequent or other Default or impair any right
consequent thereon.

Section 6.05.   Control by Majority.

       Holders of a majority in principal amount at
maturity of the then outstanding Notes may direct the time,
method and place of conducting any proceeding for exercising
any remedy available to the Trustee or exercising any trust or
power conferred on it.  However, the Trustee may refuse to
follow any direction that conflicts with law or this Indenture
that the Trustee determines may be unduly prejudicial to the
rights of other Holders or that may involve the Trustee in
personal liability.  The Trustee may take any other action
which it deems proper which is not inconsistent with any such
direction.

Section 6.06.   Limitation on Suits.

       A Holder of a Note may pursue a remedy with
respect to this Indenture or the Notes if: 

          (a)   the Holder gives to the Trustee written
    notice of a continuing Event of Default or the Trustee
    receives such notice from the Company; 

          (b)   the Holders of at least 25% in principal
    amount at maturity of the then outstanding Notes make
    a written request to the Trustee to pursue the remedy; 

          (c)   such Holder or Holders offer and, if
    requested, provide to the Trustee indemnity satisfactory
    to the Trustee against any loss, liability or expense; 

          (d)   the Trustee does not comply with the
    request within 60 days after receipt of the request and
    the offer and, if requested, the provision of indemnity;
    and 

          (e)   during such 60-day period the Holders of
    a majority in principal amount at maturity of the then
    outstanding Notes do not give the Trustee a direction
    inconsistent with the request. 

A Holder of a Note may not use this Indenture to prejudice the
rights of another Holder of a Note or to obtain a preference or
priority over another Holder of a Note.

Section 6.07.   Rights of Holders of Notes to Receive
                Payment. 

       Notwithstanding any other provision of this
Indenture, the right of any Holder of a Note to receive payment
of principal of, premium, if any, and interest on the Note, on
or after the respective due dates expressed in the Note
(including in connection with an offer to purchase), or to bring
suit for the enforcement of any such payment on or after such
respective dates, shall not be impaired or affected without the
consent of such Holder.

Section 6.08.   Collection Suit by Trustee.

       If an Event of Default specified in Section 6.01(a)
or (b) hereof occurs and is continuing, the Trustee is authorized
to recover judgment in its own name and as trustee of an
express trust against the Company or any other obligor for the
whole amount of principal of, premium, if any, and interest
remaining unpaid on the Notes and interest on overdue
principal and, to the extent lawful, interest and such further
amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and
counsel and all other amounts due the Trustee pursuant to
Section 7.07 hereof. 

Section 6.09.   Trustee May File Proofs of Claim. 

       The Trustee is authorized to file such proofs of
claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee (including
any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and
counsel) and the Holders allowed in any judicial proceedings
relative to the Company (or any other obligor upon the Notes),
its creditors or its property and shall be entitled and empowered
to collect, receive and distribute any money or other property
payable or deliverable on any such claims and any custodian in
any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee, and in the event
that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, and any
other amounts due the Trustee under Section 7.07 hereof.  To
the extent that the payment of any such compensation,
expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under
Section 7.07 hereof out of the estate in any such proceeding,
shall be denied for any reason, payment of the same shall be
secured by a Lien on, and shall be paid out of, any and all
distributions, dividends, money, securities and other properties
that the Holders may be entitled to receive in such proceeding
whether in liquidation or under any plan of reorganization or
arrangement or otherwise.  Nothing herein contained shall be
deemed to authorize the Trustee to authorize or consent to or
accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder, or to authorize
the Trustee to vote in respect of the claim of any Holder in any
such proceeding.

Section 6.10.   Priorities. 

       If the Trustee collects any money pursuant to this
Article 6, it shall pay out the money in the following order: 

          First:  to the Trustee, its agents and attorneys
    for amounts due under Section 7.07 hereof, including
    payment of all compensation, expense and liabilities
    incurred, and all advances made, by the Trustee and
    the costs and expenses of collection;

          Second:  to Holders for amounts due and
    unpaid on the Notes for principal, premium, if any, and
    interest, ratably, without preference or priority of any
    kind, according to the amounts due and payable on the
    Notes for principal, premium, if any, and interest,
    respectively;

          Third:   without duplication, to Holders for
    any other Obligations owing to the Holders under this
    Indenture or the Notes; and

          Fourth:   to the Company or to such other
    party as a court of competent jurisdiction shall direct. 

       The Trustee may fix a record date and payment
    date for any payment to Holders pursuant to this Section 6.10.

Section 6.11.   Undertaking for Costs.

       In any suit for the enforcement of any right or
remedy under this Indenture or in any suit against the Trustee
for any action taken or omitted by it as a Trustee, a court in its
discretion may require the filing by any party litigant in the suit
of an undertaking to pay the costs of the suit, and the court in
its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due
regard to the merits and good faith of the claims or defenses
made by the party litigant.  This Section does not apply to a
suit by the Trustee, a suit by a Holder pursuant to Section 6.07
hereof, or a suit by Holders of more than 10% in principal
amount at maturity of the then outstanding Notes.


                 ARTICLE 7 
                  TRUSTEE 

Section 7.01.   Duties of Trustee. 

       (a)   If an Event of Default has occurred and is
     continuing, the Trustee shall exercise such of the rights and
     powers vested in it by this Indenture, and use the same degree
     of care and skill in its exercise, as a prudent man would
     exercise or use under the circumstances in the conduct of his
     own affairs.

       (b)   Except during the continuance of an Event of
    Default: 

          (i)   the duties of the Trustee shall be
    determined solely by the express provisions of this
    Indenture or the TIA and the Trustee need perform
    only those duties that are specifically set forth in this
    Indenture or the TIA and no others, and no implied
    covenants or obligations shall be read into this
    Indenture against the Trustee; and 

          (ii)  in the absence of bad faith on its part, the
    Trustee may conclusively rely, as to the truth of the
    statements and the correctness of the opinions
    expressed therein, upon certificates or opinions
    furnished to the Trustee and conforming to the
    requirements of this Indenture.  However, the Trustee
    shall examine the certificates and opinions to determine
    whether or not they conform to the requirements of this
    Indenture.

       (c)   The Trustee may not be relieved from liability
     for its own negligent action, its own negligent failure to act, or
     its own willful misconduct, except that:

          (i)   this paragraph does not limit the effect of
    paragraph (b) of this Section 7.01;

          (ii) the Trustee shall not be liable for any
    error of judgment made in good faith by a Responsible
    Officer, unless it is proved that the Trustee was
    negligent in ascertaining the pertinent facts; and

          (iii) the Trustee shall not be liable with
    respect to any action it takes or omits to take in good
    faith in accordance with a direction received by it
    pursuant to Section 6.05 hereof.

       (d)   Whether or not therein expressly so provided,
every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b), and (c) of this Section
7.01.

       (e)   No provision of this Indenture shall require
the Trustee to expend or risk its own funds or incur any
liability.  The Trustee shall be under no obligation to exercise
any of its rights and powers under this Indenture at the request
of any Holders, unless such Holder shall have offered to the
Trustee security and indemnity satisfactory to it against any
loss, liability or expense. 

       (f)   The Trustee shall not be liable for interest on
any money received by it except as the Trustee may agree in
writing with the Company.  Money held in trust by the Trustee
need not be segregated from other funds except to the extent
required by law. 

Section 7.02.   Rights of Trustee. 

       (a)   The Trustee may conclusively rely upon any
document believed by it to be genuine and to have been signed
or presented by the proper Person.  The Trustee need not
investigate any fact or matter stated in the document. 

       (b)   Before the Trustee acts or refrains from
acting, it may require an Officers' Certificate or an Opinion of
Counsel or both.  The Trustee shall not be liable for any action
it takes or omits to take in good faith in reliance on such
Officers' Certificate or Opinion of Counsel.  The Trustee may
consult with counsel and the written advice of such counsel or
any Opinion of Counsel shall be full and complete authorization
and protection from liability in respect of any action taken,
suffered or omitted by it hereunder in good faith and in reliance
thereon.

       (c)   The Trustee may act through its attorneys and
agents and shall not be responsible for the misconduct or
negligence of any agent appointed with due care. 

       (d)   The Trustee shall not be liable for any action
it takes or omits to take in good faith that it believes to be
authorized or within the rights or powers conferred upon it by
this Indenture. 

       (e)   Unless otherwise specifically provided in this
Indenture, any demand, request, direction or notice from the
Company shall be sufficient if signed by an Officer of the
Company.  A permissive right granted to the Trustee hereunder
shall not be deemed an obligation to act.

       (f)  The Trustee shall not be charged with
knowledge of any Default or Event of Default unless either (i) a
Responsible Officer of the Trustee shall have actual knowledge
of such Default or Event of Default or (ii) written notice of
such Default or Event of Default shall have been given to the
Trustee by the Company or any Holder.

Section 7.03.   Individual Rights of Trustee.

       The Trustee in its individual or any other capacity
may become the owner or pledgee of Notes and may otherwise
deal with the Company or any Affiliate of the Company with
the same rights it would have if it were not Trustee.  However,
in the event that the Trustee acquires any conflicting interest it
must eliminate such conflict within 90 days, apply to the
Commission for permission to continue as trustee or resign. 
Any Agent may do the same with like rights and duties.  

Section 7.04.   Trustee's Disclaimer. 

       The Trustee shall not be responsible for and makes
no representation as to the validity or adequacy of this
Indenture or the Notes, it shall not be accountable for the
Company's use of the proceeds from the Notes or any money
paid to the Company or upon the Company's direction under
any provision of this Indenture, it shall not be responsible for
the use or application of any money received by any Paying
Agent other than the Trustee, and it shall not be responsible for
any statement or recital herein or any statement in the Notes or
any other document in connection with the sale of the Notes or
pursuant to this Indenture other than its certificate of
authentication. 

Section 7.05.   Notice of Defaults. 

       If a Default or Event of Default occurs and is
continuing and if it is known to a Responsible Officer of  the
Trustee, the Trustee shall mail to the Holders of the Notes a
notice of the Default or Event of Default within 90 days after it
occurs.  Except in the case of a Default or Event of Default in
payment on any Note pursuant to Section 6.01(a) or (b) hereof,
the Trustee may withhold the notice if and so long as a
committee of its Responsible Officers in good faith determines
that withholding the notice is in the interests of the Holders.

Section 7.06.   Reports by Trustee to Holders of the
                Notes.

       Within 60 days after each March 1 beginning with
the March 1 following the date of this Indenture, and for so
long as Notes remain outstanding, the Trustee shall mail to the
Holders a brief report dated as of such reporting date that
complies with TIA Section 313(a) (but if no event described in TIA
Section 313(a) has occurred within the twelve months preceding the
reporting date, no report need be transmitted).  The Trustee
also shall comply with TIA Section 313(b).  The Trustee shall also
transmit by mail all reports as required by TIA Section 313(c). 

       A copy of each report at the time of its mailing to
the Holders shall be mailed to the Company and filed with the
Commission and each stock exchange on which the Notes are
listed in accordance with TIA Section 313(d).  The Company shall
promptly notify the Trustee when the Notes are listed on any
stock exchange.

Section 7.07.   Compensation and Indemnity.

       The Company shall pay to the Trustee from time
to time reasonable compensation for its acceptance of this
Indenture and services hereunder.  The Trustee's compensation
shall not be limited by any law on compensation of a trustee of
an express trust.  The Company shall reimburse the Trustee
promptly upon request for all reasonable disbursements,
advances and expenses incurred or made by it in addition to the
compensation for its services.  Such expenses shall include the
reasonable compensation, disbursements and expenses of the
Trustee's agents and counsel.

       The Company shall indemnify the Trustee against
any and all losses, liabilities or expenses incurred by it arising
out of or in connection with the acceptance or administration of
its duties under this Indenture, including the costs and expenses
of enforcing this Indenture against the Company (including this
Section 7.07), and defending itself against any claim (whether
asserted by the Company or any Holder or any other person) or
liability in connection with the exercise or performance of any
of its powers or duties hereunder, except to the extent any such
loss, liability or expense may be attributable to its negligence or
bad faith.  The Trustee shall notify the Company promptly of
any claim for which it may seek indemnity.  Failure by the
Trustee to so notify the Company shall not relieve the
Company of its obligations hereunder.  The Company shall
defend the claim and the Trustee shall cooperate in the defense. 
The Trustee may have separate counsel and the Company shall
pay the reasonable fees and expenses of such counsel.  The
Company need not pay for any settlement made without its
consent, which consent shall not be unreasonably withheld. 

       The obligations of the Company under this Section
7.07 shall survive the resignation or removal of the Trustee and
the satisfaction and discharge of this Indenture.

       To secure the Company's payment obligations in
this Section 7.07, the Trustee shall have a Lien prior to the
Notes on all money or property held or collected by the
Trustee, except that held in trust to pay principal and interest
on particular Notes.  Such Lien shall survive the resignation or
removal of the Trustee and the satisfaction and discharge of this
Indenture. 

       When the Trustee incurs expenses or renders
services after an Event of Default specified in Section 6.01(g)
or (h) hereof occurs, the expenses and the compensation for the
services (including the fees and expenses of its agents and
counsel) are intended to constitute expenses of administration
under any Bankruptcy Law.

Section 7.08.   Replacement of Trustee. 

       A resignation or removal of the Trustee and
appointment of a successor Trustee shall become effective only
upon the successor Trustee's acceptance of appointment as
provided in this Section 7.08.

       The Trustee may resign in writing at any time and
be discharged from the trust hereby created by so notifying the
Company.  The Holders of Notes of a majority in principal
amount at maturity of the then outstanding Notes may remove
the Trustee by so notifying the Trustee and the Company in
writing.  The Company may remove the Trustee if: 

          (a)   the Trustee fails to comply with Section
    7.10 hereof; 

          (b)   the Trustee is adjudged a bankrupt or an
    insolvent or an order for relief is entered with respect
    to the Trustee under any Bankruptcy Law; 

          (c)   a Custodian or public officer takes
    charge of the Trustee or its property; or

          (d)   the Trustee becomes incapable of acting.

       If the Trustee resigns or is removed or if a
vacancy exists in the office of Trustee for any reason, the
Company shall promptly appoint a successor Trustee.

       If a successor Trustee does not take office within
60 days after the retiring Trustee resigns or is removed, the
retiring Trustee, the Company, or the Holders of at least 10%
in principal amount at maturity of the then outstanding Notes
may petition any court of competent jurisdiction for the
appointment of a successor Trustee.

       If the Trustee, after written request by any Holder
fails to comply with Section 7.10 hereof, such Holder of a Note
may petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor
Trustee.

       A successor Trustee shall deliver a written
acceptance of its appointment to the retiring Trustee and to the
Company.  Thereupon, the resignation or removal of the
retiring Trustee shall become effective, and the successor
Trustee shall have all the rights, powers and duties of the
Trustee under this Indenture.  The successor Trustee shall mail
a notice of its succession to Holders.  The retiring Trustee shall
promptly transfer all property held by it as Trustee to the
successor Trustee, provided all sums owing to the Trustee
hereunder have been paid and subject to the Lien provided for
in Section 7.07 hereof.  Notwithstanding replacement of the
Trustee pursuant to this Section 7.08, the Company's
obligations under Section 7.07 hereof shall continue for the
benefit of the retiring Trustee. 

Section 7.09.   Successor Trustee by Merger, etc. 

       If the Trustee or any Agent consolidates, merges
or converts into, or transfers all or substantially all of its
corporate trust business to another corporation, the successor
corporation without any further act shall be the successor
Trustee or Agent.

Section 7.10.   Eligibility; Disqualification. 

       There shall at all times be a Trustee hereunder that
is a corporation organized and doing business under the laws of
the United States of America or of any state thereof that is
authorized under such laws to exercise corporate trustee power,

authorities and that has a combined capital and surplus of at
least $50.0 million as set forth in its most recent published
annual report of condition.

satisfies the requirements of TIA Section 310(a)(1), (2) and (5).  The

                  ARTICLE 8
  LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01.   Option to Effect Legal Defeasance or
                Covenant Defeasance. 

    The Company may, at the option of its Board of
Directors evidenced by a resolution set forth in an Officers'
Certificate and at any time, elect to have either Section 8.02 or
8.03 hereof be applied to all outstanding Notes upon
compliance with the conditions set forth below in this Article 8.

Section 8.02.   Legal Defeasance and Discharge. 

    Upon the Company's exercise under Section 8.01
hereof of the option applicable to this Section 8.02, the
Company shall, subject to the satisfaction of the conditions set
forth in Section 8.04 hereof, be deemed to have been
discharged from its obligations with respect to all outstanding
Notes on the date the conditions set forth below are satisfied
(hereinafter, "Legal Defeasance").  For this purpose, Legal
Defeasance means that the Company shall be deemed to have
paid and discharged the entire indebtedness represented by the
outstanding Notes, which shall thereafter be deemed to be
"outstanding" only for the purposes of Section 8.05 hereof and
the other Sections of this Indenture referred to in (a) and (b) of
this Section 8.02, and to have satisfied all its other obligations
under such Notes and this Indenture (and the Trustee, on
demand of and at the expense of the Company, shall execute
proper instruments acknowledging the same), except for the
following provisions which shall survive until otherwise
terminated or discharged hereunder: (a) the rights of Holders of
outstanding Notes to receive payments in respect of the
principal of, premium, if any, and interest on such Notes when
such payments are due from the trust referred to below, or on
the redemption date, as the case may be, (b) the Company's
obligations with respect to such Notes under Sections 2.03,
2.06, 2.07, 2.10 and 4.02 hereof, (c) the rights, powers, trust,
duties and immunities of the Trustee hereunder and the
Company's obligations in connection therewith and (d) this
Article 8.  Subject to compliance with this Article 8, the
Company may exercise its option under this Section 8.02
notwithstanding the prior exercise of its option under Section
8.03 hereof.

Section 8.03.   Covenant Defeasance.

    Upon the Company's exercise under Section 8.01
hereof of the option applicable to this Section 8.03, the
Company shall, subject to the satisfaction of the conditions set
forth in Section 8.04 hereof, be released from its obligations
under the covenants contained in Sections 3.09, 4.05, 4.07,
4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, and 5.01 hereof
with respect to the outstanding Notes on and after the date the
conditions set forth below are satisfied (hereinafter, "Covenant
Defeasance"), and the Notes shall thereafter be deemed not
"outstanding" for the purposes of any direction, waiver,
consent or declaration or act of Holders (and the consequences
of any thereof) in connection with such covenants, but shall
continue to be deemed "outstanding" for all other purposes
hereunder (it being understood that such Notes shall not be
deemed outstanding for accounting purposes).  For this
purpose, Covenant Defeasance means that, with respect to the
outstanding Notes, the Company may omit to comply with and
shall have no liability in respect of any term, condition or
limitation set forth in any such covenant, whether directly or
indirectly, by reason of any reference elsewhere herein to any
such covenant or by reason of any reference in any such
covenant to any other provision herein or in any other
document and such omission to comply shall not constitute a
Default or an Event of Default under Sections 6.01(a) through
6.01(f) hereof, but, except as specified above, the remainder of
this Indenture, such Notes shall be unaffected thereby.  In
addition, upon the Company's exercise under Section 8.01
hereof of the option applicable to this Section 8.03 hereof,
subject to the satisfaction of the conditions set forth in Section
8.04 hereof, Sections 6.01(a) through 6.01(f) hereof shall not
constitute Events of Default.

Section 8.04.   Conditions to Legal or Covenant
                Defeasance.

    The following shall be the conditions to the application
of either Section 8.02 or 8.03 hereof to the outstanding Notes:

    In order to exercise either Legal Defeasance or
Covenant Defeasance:

         (a)     the Company shall irrevocably have deposited
    or caused to be irrevocably deposited with the Trustee
    (or another trustee satisfying the requirements of
    Section 7.10 who shall agree to comply with the
    provisions of this Article 8 applicable to it) as trust
    funds in trust for the purpose of making the following
    payments, specifically pledged as security for, and
    dedicated solely to, the benefit of the Holders of such
    Notes, (i) cash in Dollars in an amount, or (ii) non-
    callable Government Securities which through the
    scheduled payment of principal and interest in respect
    thereof in accordance with their terms will provide, not
    later than one day before the due date of any payment,
    cash in Dollars in an amount, or (iii) a combination
    thereof, in such amounts, as will be sufficient, in the
    opinion of a nationally recognized firm of independent
    public accountants expressed in a written certification
    thereof delivered to the Trustee, to pay and discharge
    and which shall be applied by the Trustee (or other
    qualifying trustee) to pay and discharge the principal
    of, premium, if any, and interest on the outstanding
    Notes on the stated maturity or on the applicable
    redemption date, as the case may be, of such principal
    or installment of principal of, premium, if any, and
    interest on the outstanding Notes, provided that the
    Trustee shall have been irrevocably instructed to apply
    such money or the proceeds of such non-callable
    Government Securities to said payments with respect to
    the Securities;

         (b)     in the case of an election under Section 8.02
    hereof, the Company shall have delivered to the
    Trustee an Opinion of Counsel in the United States
    reasonably acceptable to the Trustee confirming that
    (A) the Company has received from, or there has been
    published by, the Internal Revenue Service a ruling or
    (B) since the date of this Indenture, there has been a
    change in the applicable federal income tax law, in
    either case to the effect that, and based thereon such
    opinion of counsel shall confirm that, the Holders of
    the outstanding Notes will not recognize income, gain
    or loss for federal income tax purposes as a result of
    such Legal Defeasance and will be subject to federal
    income tax on the same amounts, in the same manner
    and at the same times as would have been the case if
    such Legal Defeasance had not occurred;

         (c)     in the case of an election under Section 8.03
    hereof, the Company shall have delivered to the
    Trustee an Opinion of Counsel in the United States
    reasonably acceptable to the Trustee confirming that the
    Holders of the outstanding Notes will not recognize
    income, gain or loss for federal income tax purposes as
    a result of such Covenant Defeasance and will be
    subject to federal income tax on the same amounts, in
    the same manner and at the same times as would have
    been the case if such Covenant Defeasance had not
    occurred;

         (d)     no Default or Event of Default shall have
    occurred and be continuing on the date of such deposit
    (other than a Default or Event of Default resulting from
    the borrowing of funds to be applied to such deposit)
    or, insofar as Sections 6.01(g) and 6.01(h) hereof are
    concerned, at any time in the period ending on the 91st
    day after the date of such deposit (it being understood
    that this condition shall not be deemed satisfied until
    the expiration of such period);

         (e)     such Legal Defeasance or Covenant
    Defeasance shall not result in a breach or violation of,
    or constitute a default under, any material agreement or
    instrument (other than this Indenture) to which the
    Company or any of its Subsidiaries is a party or by
    which the Company or any of its Subsidiaries is bound;

         (f)     the Company shall have delivered to the
    Trustee an Opinion of Counsel to the effect that after
    the 91st day following the deposit, (A) no Event of
    Default under Sections 6.01(g) and 6.01(h) hereof shall
    have occurred and (B) the trust funds are not, as of the
    date of such opinion, subject to the effect of any
    applicable bankruptcy, insolvency, reorganization or
    similar laws affecting creditors' rights generally;

         (g)     the Company shall have delivered to the
    Trustee an Officers' Certificate stating that the deposit
    was not made by the Company with the intent of
    preferring the Holders over any other creditors of the
    Company with the intent of defeating, hindering,
    delaying or defrauding creditors of the Company or
    others; and

         (h)     the Company shall have delivered to the
    Trustee an Officers' Certificate and an Opinion of
    Counsel, each stating that all conditions precedent
    provided for or relating to the Legal Defeasance or the
    Covenant Defeasance have been complied with.

Section 8.05.   Deposited Money and Government
                Securities to be Held in Trust; Other
                Miscellaneous Provisions.

    Subject to Section 8.06 hereof, all money and non-
callable Government Securities (including the proceeds thereof)
deposited with the Trustee (or other qualifying trustee,
collectively for purposes of this Section 8.05, the "Trustee")
pursuant to Section 8.04 hereof in respect of the outstanding
Notes shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Notes and this
Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as Paying Agent)
as the Trustee may determine, to the Holders of such Notes of
all sums due and to become due thereon in respect of principal,
premium, if any, and interest, but such money need not be
segregated from other funds except to the extent required by
law.

       The Company shall pay and indemnify the Trustee
against any tax, fee or other charge imposed on or assessed
against the cash or non-callable Government Securities
deposited pursuant to Section 8.04 hereof or the principal and
interest received in respect thereof other than any such tax, fee
or other charge which by law is for the account of the Holders
of the outstanding Notes.

       Anything in this Article 8 to the contrary
notwithstanding, the Trustee shall deliver or pay to the
Company from time to time upon the request of the Company
any money or non-callable Government Securities held by it as
provided in Section 8.04 hereof which, in the opinion of a
nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the
Trustee (which may be the opinion delivered under
Section 8.04(a) hereof), are in excess of the amount thereof that
would then be required to be deposited to effect an equivalent
Legal Defeasance or Covenant Defeasance.

Section 8.06.   Repayment to Company.

       The Trustee shall promptly pay to the Company,
after written request therefor, any money held at such time in
excess of the amounts required to pay any of the Company's
Obligations then owing with respect to the Notes.

       Any money deposited with the Trustee or any
Paying Agent, or then held by the Company, in trust for the
payment of the principal of, premium, if any, or interest, if
any, on any Note and remaining unclaimed for one year after
such principal, and premium, if any, or interest, if any, have
become due and payable shall be paid to the Company on its
request or (if then held by the Company) shall be discharged
from such trust; and the Holder of such Note shall thereafter,
as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease; provided,
however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of
the Company cause to be published once, in The New York
Times and The Wall Street Journal (national edition), notice
that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the
date of such notification or publication, any unclaimed balance
of such money then remaining will be repaid to the Company.

Section 8.07.   Reinstatement.

       If the Trustee or Paying Agent is unable to apply
any cash or non-callable Government Securities in accordance
with Section 8.02 or 8.03 hereof, as the case may be, by reason
of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this
Indenture and the Notes shall be revived and reinstated as
though no deposit had occurred pursuant to Section 8.02 or
8.03 hereof until such time as the Trustee or Paying Agent is
permitted to apply all such money in accordance with
Section 8.02 or 8.03 hereof, as the case may be; provided,
however, that, if the Company makes any payment of principal
of, premium, if any, or interest, if any, on any Note following
the reinstatement of its obligations, the Company shall be
subrogated to the rights of the Holders of such Notes to receive
such payment from the money held by the Trustee or Paying
Agent.




                  ARTICLE 9
      AMENDMENT, SUPPLEMENT AND WAIVER 

Section 9.01.   Without Consent of Holders of Notes.

       Notwithstanding Section 9.02 hereof, the
Company and the Trustee may amend or supplement this
Indenture or the Notes without the consent of any Holder of a
Note:

          (a)   to cure any ambiguity, defect or
    inconsistency;

          (b)   to provide for uncertificated Notes in
    addition to or in place of certificated Notes; 

          (c)   to provide for the assumption of the
    Company's obligations under this Indenture to the
    Holders in the case of a merger or consolidation;

          (d)   to make any change that would provide
    any additional rights or benefits to the Holders of the
    Notes or that does not adversely affect the legal rights
    hereunder of any Holder of the Note; or

          (e)   to comply with requirements of the
    Commission in order to effect or maintain the
    qualification of this Indenture under the TIA.

       Upon the request of the Company accompanied by
a Board Resolution authorizing the execution of any such
supplemental indenture, and upon receipt by the Trustee of the
documents described in Section 9.06 hereof, the Trustee shall
join with the Company in the execution of any amended or
supplemental indenture authorized or permitted by the terms of
this Indenture and to make any further appropriate agreements
and stipulations that may be therein contained, but the Trustee
shall not be obligated to enter into such amended or
supplemental indenture that affects its own rights, duties or
immunities under this Indenture or otherwise. 

Section 9.02.   With Consent of Holders of Notes.

       Except as provided below in this Section 9.02, the
Company and the Trustee may amend or supplement this
Indenture or the Notes with the consent of the Holders of at
least a majority in principal amount at maturity of the Notes
then outstanding (including consents obtained in connection
with a tender offer or exchange offer for the Notes), and any
existing Default or Event of Default (other than a Default or
Event of Default in the payment of the principal of, premium,
if any, or interest on the Notes, except a payment default
resulting from an acceleration that has been rescinded) or
compliance with any provision of this Indenture or the Notes
may be waived with the consent of the Holders of a majority in
principal amount at maturity of the then outstanding Notes
(including consents obtained in connection with a tender offer
or exchange offer for the Notes).

       Upon the request of the Company accompanied by
a Board Resolution, authorizing the execution of any such
amended or supplemental indenture, and upon the filing with
the Trustee of evidence reasonably satisfactory to the Trustee of
the consent of the Holders of Notes as aforesaid, and upon
receipt by the Trustee of the documents described in Section
9.06 hereof, the Trustee shall join with the Company in the
execution of such amended or supplemental indenture unless
such amended or supplemental indenture affects the Trustee's
own rights, duties or immunities under this Indenture or
otherwise, in which case the Trustee may in its discretion, but
shall not be obligated to, enter into such amended or
supplemental indenture.

       It shall not be necessary for the consent of the
Holders of Notes under this Section 9.02 to approve the
particular form of any proposed amendment or waiver, but it
shall be sufficient if such consent approves the substance
thereof.

       After an amendment, supplement or waiver under
this Section 9.02 becomes effective, the Company shall mail to
the Holders of Notes affected thereby a notice briefly
describing the amendment, supplement or waiver.  Any failure
of the Company to mail such notice, or any defect therein, shall
not, however, in any way impair or affect the validity of any
such supplemental indenture or waiver.  Subject to Sections
6.04 and 6.07 hereof, the Holders of a majority in aggregate
principal amount at maturity of the Notes then outstanding may
waive any existing default or compliance in a particular
instance by the Company with any provision of this Indenture
or the Notes.  Without the consent of each Holder affected,
however, an amendment or waiver may not (with respect to
any Note held by a non-consenting Holder);

          (a)   reduce the principal amount at maturity
    of Notes whose Holders must consent to an
    amendment, supplement or waiver;

          (b)   reduce the principal of or change the
    fixed maturity date of any Note, alter any of the
    provisions with respect to the redemption of the Notes
    or alter the price at which the Company must offer to
    purchase the Notes pursuant to an Asset Sale Offer or
    any Change of Control Offer;

          (c)   reduce the rate of or change the time for
    payment of interest on any Note;

          (d)   waive a Default or Event of Default in
    the payment of principal of or premium, if any, or
    interest on the Notes (except a rescission of
    acceleration of the Notes by the Holders of at least a
    majority in aggregate principal amount at maturity
    thereof and a waiver of the payment default that
    resulted from such acceleration), including any
    payment pursuant to an Asset Sale Offer or a Change
    of Control Offer;

          (e)   make any Note payable in money other
    than that stated in the Notes;

          (f)   make any change in the provisions of this
    Indenture relating to waivers of past Defaults or the
    rights of Holders of Notes to receive payments of
    principal of, premium, if any, or interest on the Notes.

          (g)   waive a redemption or purchase payment
    with respect to any Note; or

          (h)   make any change in the foregoing
    amendment and waiver provisions.

       
Section 9.03.   Compliance with Trust Indenture Act.

       Every amendment to this Indenture or the Notes
shall be set forth in a supplemental indenture that complies with
the TIA as then in effect.

Section 9.04.   Revocation and Effect of Consents.

       Until an amendment, supplement or waiver
becomes effective, a consent to it by a Holder is a continuing
consent by the Holder and every subsequent Holder of a Note
or portion of a Note that evidences the same debt as the
consenting Holder's Note, even if notation of the consent is not
made on any Note.  However, any such Holder or subsequent
Holder of a Note may revoke the consent as to its Note if the
Trustee receives written notice of revocation before the date the
waiver, supplement or amendment becomes effective.  An
amendment, supplement or waiver becomes effective in
accordance with its terms and thereafter binds every Holder.

       The Company may, but shall not be obligated to,
fix a record date for determining which Holders must consent
to such amendment or waiver.  If the Company fixes a record
date, the record date shall be fixed at (i) the later of 30 days
prior to the first solicitation of such consent or the date of the
most recent list of Holders furnished to the Trustee prior to
such solicitation pursuant to Section 2.05 hereof or (ii) such
other date as the Company shall designate.

Section 9.05.   Notation on or Exchange of Notes. 

       The Trustee may place an appropriate notation
about an amendment, supplement or waiver on any Note
thereafter authenticated.  The Company in exchange for all
Notes may issue and the Trustee shall authenticate new Notes
that reflect the amendment, supplement or waiver.

       Failure to make the appropriate notation or issue a
new Note shall not affect the validity and effect of such
amendment, supplement or waiver.

Section 9.06.   Trustee to Sign Amendments, etc. 

       The Trustee shall sign any amendment or
supplemental indenture authorized pursuant to this Article 9 if
the amendment does not adversely affect the rights, duties,
liabilities or immunities of the Trustee.  The Company may not
sign an amendment or supplemental indenture until the Board
of Directors of the Company approves it.  In signing or
refusing to sign any amended or supplemental indenture, the
Trustee shall be entitled to receive and (subject to Section 7.01
hereof) shall be fully protected in relying upon, in addition to
the documents required by Section 10.04 hereof, an Officers'
Certificate and an Opinion of Counsel as conclusive evidence
that such amendment or supplemental indenture is authorized or
permitted by this Indenture, that it is not inconsistent herewith,
and that it will be valid and binding upon the Company in
accordance with its terms.

Section 314(a)(4)) shall comply with the provisions of TIA Section 314(e)
and shall include: 

          (a)   a statement that the Person making such
    certificate or opinion has read such covenant or
    condition; 

          (b)   a brief statement as to the nature and
    scope of the examination or investigation upon which
    the statements or opinions contained in such certificate
    or opinion are based; 

          (c)   a statement that, in the opinion of such
    Person, he or she has made such examination or
    investigation as is necessary to enable him to express an
    informed opinion as to whether or not such covenant or
    condition has been satisfied; and 

          (d)   a statement as to whether or not, in the
    opinion of such Person, such condition or covenant has
    been satisfied. 

Section 10.06.  Rules by Trustee and Agents. 

       The Trustee may make reasonable rules for action
by or at a meeting of Holders.  The Registrar or Paying Agent
may make reasonable rules and set reasonable requirements for
its functions. 

Section 10.07.  No Personal Liability of Directors,
                Officers, Employees and Stockholders.

       No past, present or future director, officer,
employee, incorporator or stockholder of the Company shall
have any liability for any obligations of the Company under the
Notes, any guarantee thereof or this Indenture or for any claim
based on, in respect of, or by reason of, such obligations or
their creation.  Each Holder of Notes by accepting a Note
waives and releases all such liability.  The waiver and release
are part of the consideration for issuance of the Notes.  Such
waiver may not be effective to waive liabilities under the
federal securities laws and it is the view of the Commission that
such a waiver is against public policy.

Section 10.08.  Governing Law. 

       THE INTERNAL LAW OF THE STATE OF
NEW YORK SHALL GOVERN AND BE USED TO
CONSTRUE THIS INDENTURE AND THE NOTES. 

Section 10.09.  No Adverse Interpretation of Other
                Agreements. 

       This Indenture may not be used to interpret any
other indenture, loan or debt agreement of the Company or its
Subsidiaries or of any other Person.  Any such indenture, loan
or debt agreement may not be used to interpret this Indenture. 

Section 10.10.  Successors. 

       All agreements of the Company in this Indenture
and the Notes shall bind its successors.  All agreements of the
Trustee in this Indenture shall bind its successors. 

Section 10.11.  Severability. 

       In case any provision in this Indenture or in the
Notes shall be invalid, illegal or unenforceable, the validity,
legality and enforceability of the remaining provisions shall not
in any way be affected or impaired thereby. 

Section 10.12.  Counterpart Originals.

       The parties may sign any number of copies of this
Indenture.  Each signed copy shall be an original, but all of
them together represent the same agreement.

Section 10.13.  Table of Contents, Headings, etc.

       The Table of Contents, Cross-Reference Table and
Headings of the Articles and Sections of this Indenture have
been inserted for convenience of reference only, are not to be
considered a part of this Indenture and shall in no way modify
or restrict any of the terms or provisions hereof.

Section 10.14.  Trustee To Include Paying Agent. 

       In case at any time any Paying Agent other than
the Trustee shall have been appointed by the Company and be
then acting hereunder, the term "Trustee" as used in this
Article 10 shall in such case (unless the context shall otherwise
require) be construed as extending to and including such Paying
Agent within its meaning as fully and for all intents and
purposes as if such Paying Agent were named in this Article 10
in place of the Trustee.

             (Back of Security)

          11% SENIOR NOTES due 2006
                     of
             UNILAB CORPORATION
                      

         Capitalized terms used herein have the
meanings assigned to them in the Indenture (referred to below)
unless otherwise indicated.

         1.   Interest.  Unilab Corporation, a
Delaware corporation (the "Company"), promises to pay
interest on the principal amount at maturity of the 11% Senior
Notes due 2006 (the "Notes") of which this Note is a part at the
rate and in the manner specified below.

         The Company shall pay interest on the
principal amount at maturity of this Note in cash at the rate per
annum shown above.  The Company will pay interest semi-
annually in arrears on April 1 and October 1 of each year,
commencing on October 1, 1996, or if any such day is not a
Business Day (as defined in the Indenture), on the next
succeeding Business Day (each an "Interest Payment Date") to
Holders of record on the immediately preceding March 15 and
September 15.

         Interest will be computed on the basis of a 360-
day year comprised of twelve 30-day months.  Interest shall
accrue from the most recent date to which interest has been
paid or, if no interest has been paid, from the date of the
original issuance of the Notes.  To the extent lawful, the
Company shall pay interest on overdue principal at the rate of
1% per annum in excess of the then applicable interest rate on
the Notes; it shall pay interest on overdue installments of
interest (without regard to any applicable grace periods) at the
same rate to the extent lawful.

         2.   Method of Payment.  The Company
will pay interest on the Notes (except defaulted interest) to the
Persons who are registered Holders of Notes at the close of
business on March 15 and September 15 next preceding the
Interest Payment Date, even if such Notes are cancelled after
such record date and on or before such Interest Payment Date,
except as provided in Section 2.12 of the Indenture with respect
to defaulted interest.  The Notes will be payable as to principal,
premium, if any, and interest at the office or agency of the
Company maintained in the City of New York; provided
however, payment of interest may be made by check mailed to
the Holders at their addresses set forth in the register of
Holders.  Such payment shall be in such coin or currency of the
United States of America as at the time of payment is legal
tender for payment of public and private debts.

         3.   Paying Agent and Registrar.  Initially,
the Trustee under the Indenture will act as Paying Agent and
Registrar.  The Company may change any Paying Agent,
Registrar or co-registrar without notice to any Holder.  The
Company may act in any such capacity.

         4.   Indenture.  The Company issued the
Notes under an Indenture dated as of March 14, 1996 (the
"Indenture") between the Company and Marine Midland Bank,
as Trustee.  The terms of the Notes include those stated in the
Indenture and those made part of the Indenture by reference to
the Trust Indenture Act of 1939 (15 U.S.
Code Sections (77aaa-77bbbb) as in effect on the date of the
Indenture.  The Notes are subject to all such terms, and
Holders of the Notes are referred to the Indenture and such act
for a statement of such terms.  The terms of the Indenture shall
govern any inconsistencies between the Indenture and the
Notes.  The Notes are unsecured general Obligations of the
Company limited to $120,000,000 in aggregate principal
amount at maturity, plus amounts, if any, sufficient to pay
interest and premium, if any, on outstanding Notes as set forth
in Paragraph 1 hereof.

         5.   Optional Redemption.  Except as
provided in the next paragraph, the Notes will not be
redeemable at the Company's option prior to April 1, 2001. 
Thereafter, the Notes will be subject to redemption at the
option of the Company, in whole or in part, upon not less than
30 nor more than 60 days' notice, at the redemption prices
(expressed as percentages of the principal amount at maturity)
set forth below plus accrued and unpaid interest thereon to the
applicable redemption date, if redeemed during the twelve-
month period beginning on April 1 of the years indicated
below:  

    Year                 Percentage

    2001                 105.500%
    2002                 103.667%
    2003                 101.833%
    2004 and thereafter  100.000%

         Notwithstanding the foregoing, at any time
prior to April 1, 1999, the Company may on one or more
occasions redeem up to $42.0 million in aggregate principal
amount at maturity of Notes with the net proceeds of one or
more public offerings of common stock of the Company at a
redemption price equal to 110% of the principal amount at
maturity thereof, plus accrued and unpaid interest therein to the
applicable date of redemption; provided, that at least $78.0
million in aggregate principal amount at maturity of Notes
remain outstanding immediately after the occurrence of each
such redemption; and provided, further, that any such
redemption must occur within 90 days of the date of the closing
of such public offering.

         6.   Mandatory Redemption.  Except as set
forth under Section 3.09, Section 4.10 and Section 4.15 of the
Indenture, the Company shall not be required to make
mandatory redemption or sinking fund payments with respect to
the Notes.

         7.   Repurchase at the Option of Holders. 
(a)  Upon the occurrence of a Change of Control, each Holder
shall have the right to require the Company to repurchase all or
any part (equal to $1,000 or an integral multiple thereof) of
such Holder's Notes pursuant to the offer described in the
Indenture (the "Change of Control Offer") at an offer price in
cash equal to 101% of the aggregate principal amount at
maturity thereof plus accrued and unpaid interest, if any,
thereon to the date of purchase.

         (b)  When the aggregate amount of Excess
Proceeds from Asset Sales exceeds $5.0 million, the Company
shall make an offer to all Holders to purchase the maximum
principal amount at maturity of Notes that may be purchased
out of the Excess Proceeds at an offer price in cash equal to
100% of the principal amount at maturity thereof plus accrued
and unpaid interest thereon to the date fixed for the closing of
such offer, in accordance with the procedures set forth in the
Indenture.  If the aggregate principal amount at maturity of
Notes surrendered by Holders thereof exceeds the amount of
Excess Proceeds, the Trustee shall select the Notes to be
purchased on a pro rata basis.  To the extent that the aggregate
amount of Notes tendered pursuant to an Asset Sale Offer is
less than the Excess Proceeds, the Company may use such
deficiency for general corporate purposes.

         (c)  Holders that are the subject of an offer to
purchase will receive a Change of Control Offer or Asset Sale
Offer from the Company prior to any related purchase date,
and may elect to have such Notes purchased by completing the
form entitled "Option of Holder to Elect Purchase" appearing
below.

         8.   Notice of Redemption.  Notice of
redemption shall be mailed at least 30 days but not more than
60 days before the redemption date to each Holder of Notes to
be redeemed at its registered address.  Notes may be redeemed
in part but only in whole multiples of $1,000, unless all of the
Notes held by a Holder are to be redeemed.  On and after the
redemption date, interest ceases to accrue on Notes or portions
thereof called for redemption.

         9.   Denominations, Transfer, Exchange. 
The Notes are in registered form without coupons in
denominations of $1,000 and integral multiples of $1,000.  The
transfer of Notes may be registered and Notes may be
exchanged as provided in the Indenture.  The Registrar and the
Trustee may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and to pay
any taxes and fees required by law or permitted by the
Indenture.  The Registrar need not exchange or register the
transfer of any Note or portion of a Note selected for
redemption or purchase, except for the unredeemed or
unpurchased portion of any Note being redeemed or
repurchased in part.  Also, it need not exchange or register the
transfer of any Notes for a period of 15 days before a selection
of Notes to be redeemed or repurchased during the period
between a record date and the corresponding interest payment
date.

         10.  Persons Deemed Owners.  The
registered holder of a Note shall be treated as its owner for all
purposes.

         11.  Amendments and Waivers.  Subject to
certain exceptions, the Indenture or the Notes may be amended
with the consent of the Holders of at least a majority in
principal amount at maturity of the then outstanding Notes
(including consents obtained in connection with a tender offer
or exchange offer for Notes), and any existing Default or Event
of Default (other than a Default or Event of Default in the
payment of the principal of, premium, if any, or interest on the
Notes, except a payment default resulting from an acceleration
that has been rescinded) or compliance with any provision of
the Indenture or the Notes may be waived with the consent of
the Holders of a majority in principal amount at maturity of the
then outstanding Notes (including consents obtained in
connection with a tender offer or exchange offer for Notes). 
Without the consent of any Holder, the Indenture or the Notes
may be amended to cure any ambiguity, defect or
inconsistency, to provide for uncertificated Notes in addition to
or in place of certificated Notes, to provide for the assumption
of the Company's obligations under the Indenture to Holders in
the case of a merger or consolidation, to make any change that
would provide any additional rights or benefits to the Holders
or that does not adversely affect the legal rights of any Holder
under the Indenture, or to comply with the requirements of the
Commission in order to effect or maintain the qualification of
the Indenture under the TIA.

         Notwithstanding the foregoing, without the
consent of each Holder affected, an amendment or waiver may
not (with respect to any Notes held by a non-consenting
Holder): (i) reduce the principal amount at maturity of Notes
whose Holders must consent to an amendment, supplement or
waiver, (ii) reduce the principal or change the fixed maturity
date of any Note or alter the provisions with respect to the
redemption of the Notes, or alter the price at which the
Company must offer to purchase the Notes pursuant to an Asset
Sale Offer or a Change of Control Offer, (iii) reduce the rate of
or change the time for payment of interest, on any Note, (iv)
waive a Default or Event of Default in the payment of principal
of or premium, if any, or interest, on the Notes (except a
rescission of acceleration of the Notes by the Holders of at least
a majority in aggregate principal amount at maturity thereof
and a waiver of the payment default that resulted from such
acceleration), including any payment pursuant to an Asset Sale
Offer or a Change of Control Offer, (v) make any note payable
in money other than that stated in the Notes, (vi) make any
change in the provisions of the Indenture relating to waivers of
past Defaults or the rights of Holders of notes to receive
payments of principal of, premium, if any, or interest on the
Notes, (vii) waive a redemption or purchase payment with
respect to any Note or (viii) make any change in the foregoing
amendment and waiver provisions.

         12.  Defaults and Remedies.  Events of
Default occur if:  (a) the Company defaults in the payment of
interest on the Notes when the same becomes due and payable
and such default continues for a period of thirty (30) days; (b)
the Company defaults in the payment of principal of or
premium, if any, on the Notes when the same becomes due and
payable at maturity, upon redemption or otherwise; (c) the
Company fails to comply with the provisions of Sections 4.07,
4.10 and 5.01 of the Indenture and such Default continues for a
period of thirty (30) days; (d) the Company fails to comply
with any other agreement or covenant in, or provision of, the
Notes or the Indenture for sixty (60) days after notice from the
Trustee or Holders of at least 25% in aggregate principal
amount at maturity of the then outstanding Notes; (e) a default
occurs under any mortgage, indenture or instrument under
which there may be issued or by which there may be secured or
evidenced any Indebtedness for money borrowed by the
Company or any of its Restricted Subsidiaries (or the payment
of which is guaranteed by the Company or any of its Restricted
Subsidiaries) whether such Indebtedness or Guarantee now
exists, or is created after the date of the Indenture, which
default (i) is caused by a failure to pay when due the final
scheduled principal installment on the stated maturity thereof
prior to the expiration of the grace period set forth in the
documents governing such Indebtedness (a "Payment Default")
or (ii) results in the acceleration of such Indebtedness prior to
its express maturity and, in each case, the principal amount of
any such Indebtedness, together with the principal amount of
any other such Indebtedness under which there has been a
Payment Default or the maturity of which has been so
accelerated, aggregates $5.0 million or more; (f) the Company
or any of its Restricted Subsidiaries fails to pay final judgments
aggregating in excess of $5.0 million, if (A) any creditor has
commenced an enforcement proceeding with respect to such
final judgments or (B) such judgments are not discharged or
stayed within 60 days of their entry; or (g) certain events of
bankruptcy with respect to the Company or any Restricted
Subsidiary that is a Significant Subsidiary or group of
Restricted Subsidiaries that, together, would constitute a
Significant Subsidiary.

         If any Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in
principal amount at maturity of the then outstanding Notes may
declare all the Notes to be due and payable and the same (i)
shall become immediately due and payable or (ii) if there are
any amounts outstanding under the New Credit Facility (as
defined in the Indenture), shall become due and payable upon
the first to occur of an acceleration under the New Credit
Facility or five business days after receipt by the Company and
the administrative agent under the New Credit Facility of notice
of such acceleration under the Indenture if such Event of
Default is continuing at such time.  Notwithstanding the
foregoing, in the case of an Event of Default arising from
certain events of bankruptcy or insolvency, with respect to the
Company, all outstanding Notes will become due and payable
without further action or notice.  Holders of the Notes may not
enforce the Indenture or the Notes except as provided in the
Indenture.  

         Subject to certain limitations, Holders of a
majority of principal amount at maturity of the then outstanding
Notes may direct the Trustee in its exercise of any trust or
power.  The Trustee may withhold from Holders of the Notes
notice of any continuing Default or Event of Default (except a
Default or Event of Default relating to the payment of principal
or interest) if it determines that withholding notice is in their
interest.

         13.  Trustee Dealings with Company.  The
Trustee, in its individual or any other capacity, may make loans
to, accept deposits from, and perform services for the
Company or its Affiliates, and may otherwise deal with the
Company or its Affiliates, as if it were not Trustee.

         14.  No Recourse Against Others.  No past,
present or future director, officer, employee, incorporator or
stockholder, as such, of the Company shall have any liability
for any obligations of the Company under the Notes or the
Indenture or for any claim based on, in respect of or by reason
of such obligations or their creation.  Each Holder by accepting
a Note waives and releases all such liability.  The waiver and
release are part of the consideration for the issuance of the
Notes.  Such waiver may not be effective to waive liabilities
under the federal securities laws and it is the view of the
Commission that such a waiver is against public policy.

         15.  Authentication.  This Note shall not be
valid until authenticated by the manual signature of the Trustee
or an authenticating agent.

         16.  Abbreviations.  Customary
abbreviations may be used in the name of a Holder or an
assignee, such as:  TEN COM (= tenants in common), TEN
ENT (= tenants by the entireties), JT TEN (= joint tenants
with right of survivorship and not as tenants in common),
CUST (= Custodian), and U/G/M/A (= Uniform Gifts to
Minors Act).

         17.  CUSIP Numbers.  Pursuant to a
recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Notes and has directed the
Trustee to use CUSIP numbers in notices of redemption as a
convenience to Holders.  No representation is made as to the
accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be
placed only on the other identification numbers placed thereon.

         18.  Governing Law.  THE INTERNAL
LAW OF THE STATE OF NEW YORK SHALL GOVERN
AND BE USED TO CONSTRUE THE INDENTURE AND
THE NOTES.

         The Company will furnish to any Holder upon
written request and without charge a copy of the Indenture. 
Request may be made to:

   CREDIT AGREEMENT, dated as of March 14, 1996,
   among UNILAB CORPORATION, a Delaware corporation (the
   "Borrower"), the financial institutions party hereto from time to
   time (each, a "Bank," and collectively, the "Banks") and BANQUE
   PARIBAS, as agent (the "Agent") for the Banks.  Unless otherwise
   defined herein, all capitalized terms used herein and defined in
   Section 11 are used herein as therein defined.
   
   
                        W I T N E S S E T H :
   
   
     WHEREAS, subject to and upon the terms and conditions
   herein set forth, the Banks are willing to make available to the
   Borrower the respective credit facilities provided for herein;
   
   
     NOW, THEREFORE, IT IS AGREED:
   
     Section 1.  Amount and Terms of Credit.
   
     1.01  Revolving Commitment.  (a)  Subject to and upon the
   terms and conditions set forth herein, each Bank severally agrees,
   at any time and from time to time on or after the Effective Date and
   prior to the Revolving Loan Maturity Date, to make a loan or loans
   (each a "Revolving Loan" and, collectively, the "Revolving Loans")
   to the Borrower, which Revolving Loans:  
   
        (i)   shall, at the option of the Borrower, be Base
        Rate Loans or Eurodollar Loans, provided that except as
        otherwise specifically provided in Section 1.10(b), all
        Revolving Loans comprising the same Borrowing shall at all
        times be of the same Type;
   
       (ii)   may be repaid and reborrowed in accordance
        with the provisions hereof;
   
     (iii)     shall not exceed for any Bank at any time out-
        
        standing that aggregate principal amount which, when added
        to the product of (x) such Bank's Percentage and (y) the sum
        of (I) the aggregate amount of all Letter of Credit Out-
        
        standings (exclusive of Unpaid Drawings which are repaid
        with the proceeds of, and simultaneously with the incurrence
        of, the respective incurrence of Revolving Loans) at such
        time and (II) the aggregate principal amount of all Swingline
        Loans (exclusive of Swingline Loans which are repaid with
        the proceeds of, and simultaneously with the incurrence of,
        the respective incurrence of Revolving Loans) then
        outstanding, equals the Revolving Loan Commitment of
        such Bank at such time; and
   
      (iv)     shall not exceed for all Banks at any time
        outstanding that aggregate principal amount which, when
        added to (x) the amount of all Letter of Credit Outstandings
        (exclusive of Unpaid Drawings which are repaid with the
        proceeds of, and simultaneously with the incurrence of, the
        respective incurrence of Revolving Loans) at such time and
        (y) the aggregate principal amount of all Swingline Loans
        (exclusive of Swingline Loans which are repaid with the
        proceeds of, and simultaneously with the incurrence of, the
        respective incurrence of Revolving Loans) then outstanding,
        equals the lesser of (A) the Total Revolving Loan
        Commitment at such time and (B) the Borrowing Base at
        such time. 
   
     (b)  Subject to and upon the terms and conditions herein set
   forth, Paribas in its individual capacity agrees to make at any time
   and from time to time after the Effective Date and prior to the
   Swingline Expiry Date, a revolving loan or revolving loans (each,
   a "Swingline Loan" and, collectively, the "Swingline Loans") to the
   Borrower, which Swingline Loans (i) shall be made and maintained
   as Base Rate Loans, (ii) may be repaid and reborrowed in
   accordance with the provisions hereof, (iii) shall not exceed in
   aggregate principal amount at any time outstanding, when combined
   with the aggregate principal amount of all Revolving Loans then
   outstanding and the Letter of Credit Outstandings (exclusive of
   Unpaid Drawings which are repaid with the proceeds of, and
   simultaneously with the incurrence of, the respective incurrence of
   Revolving Loans) at such time, an amount equal to the lesser of (x)
   the Total Revolving Loan Commitment at such time and (y) the
   Borrowing Base at such time and (iv) shall not exceed at any time
   outstanding the Maximum Swingline Amount; provided that Paribas
   shall be under no obligation to make any Swingline Loan if on the
   proposed date of Borrowing thereof a Bank Default exists unless
   Paribas has entered into arrangements satisfactory to it and the
   Borrower to eliminate Paribas' risk with respect to the Bank which
   is the subject of the Bank Default, including by cash collateralizing
   such Bank's Percentage of the then outstanding Swingline Loans.
   
     (c)  On any Business Day, Paribas may, in its sole
   discretion, give notice to the Banks that its outstanding Swingline
   Loans shall be funded with a Borrowing of Revolving Loans
   (provided that such notice shall be deemed to have been
   automatically given upon the occurrence of a Default or an Event
   of Default under Section 10.05 or upon the exercise of any of the
   remedies provided in the last paragraph of Section 10), in which
   case a Borrowing of Revolving Loans constituting Base Rate Loans
   (each such Borrowing, a "Mandatory Borrowing") shall be made on
   the immediately succeeding Business Day by all Banks with a
   Revolving Loan Commitment (without giving effect to any
   reductions thereto pursuant to the last paragraph of Section 10) pro
   rata based on each Bank's Percentage (determined before giving
   effect to any termination of the Revolving Loan Commitments
   pursuant to the last paragraph of Section 10) and the proceeds
   thereof shall be applied directly to Paribas to repay Paribas for such
   outstanding Swingline Loans.  Each such Bank hereby irrevocably
   agrees to make Revolving Loans upon one Business Day's notice
   pursuant to each Mandatory Borrowing in the amount and in the
   manner specified in the preceding sentence and on the date specified
   in writing by Paribas notwithstanding (i) the amount of the
   Mandatory Borrowing may not comply with the minimum amount
   for Borrowings otherwise required hereunder, (ii) whether any
   conditions specified in Section 5 or 6 are then satisfied, (iii)
   whether a Default or an Event of Default then exists, (iv) the date
   of such Mandatory Borrowing, (v) the amount of the Borrowing
   Base at such time and (vi) any reduction or termination of the Total
   Revolving Loan Commitment since the corresponding Swingline
   Loans were first made.  In the event that any Mandatory Borrowing
   cannot for any reason be made on the date otherwise required above
   (including, without limitation, as a result of the commencement of
   a proceeding under the Bankruptcy Code with respect to the
   Borrower), then each such Bank (other than Paribas) hereby agrees
   that it shall forthwith purchase (as of the date the Mandatory
   Borrowing would otherwise have occurred, but adjusted for any
   payments received from the Borrower on or after such date and
   prior to such purchase and without recourse or warranty) from
   Paribas such participations in the outstanding Swingline Loans as
   shall be necessary to cause such Banks to share in such Swingline
   Loans ratably based upon their respective Percentages (determined
   before giving effect to any termination of the Revolving Loan
   Commitments pursuant to the last paragraph of Section 10),
   provided that (x) all interest payable on the Swingline Loans shall
   be for the account of Paribas until the date as of which the
   respective participation is required to be purchased and, to the
   extent attributable to the purchased participation, shall be payable
   to the participant from and after such date and (y) at the time any
   purchase of participations pursuant to this sentence is actually made,
   the purchasing Bank shall be required to pay Paribas interest on the
   principal amount of participation purchased for each day from and
   including the day upon which the Mandatory Borrowing would
   otherwise have occurred to but excluding the date of payment for
   such participation, at the overnight Federal Funds Rate for the first
   three days and at the rate otherwise applicable to Revolving Loans
   maintained as Base Rate Loans hereunder for each day thereafter.
   
     1.02  Minimum Amount of Each Borrowing.  The aggregate
   principal amount of each Borrowing hereunder shall not be less than
   the applicable Minimum Borrowing Amount and, if greater, shall
   be in integral multiples of (i) for Base Rate Loans (other than
   Swingline Loans), $100,000, (ii) for Eurodollar Loans, $500,000
   or (iii) for Swingline Loans, $100,000, provided that Mandatory
   Borrowings shall be made in the amounts required by Section
   1.01(c).  More than one Borrowing may occur on the same date,
   but at no time shall there be outstanding more than four Borrowings
   of Eurodollar Loans.
   
     1.03  Notice of Borrowing.   (a) Whenever the Borrower desires
   to make a Borrowing hereunder (excluding Borrowings of
   Swingline Loans and Mandatory Borrowings), it shall give the
   Agent at its Notice Office, prior to 12:00 Noon (New York time)
   at least one Business Day's prior written notice (or telephonic notice
   promptly confirmed in writing) of each Borrowing of Base Rate
   Loans and at least three Business Days' prior written notice (or
   telephonic notice promptly confirmed in writing) of each Borrowing
   of Eurodollar Loans to be made hereunder.  Each such notice (each
   a "Notice of Borrowing"), except as otherwise expressly provided
   in Section 1.10, shall be irrevocable and shall be given by the
   Borrower in the form of Exhibit A, appropriately completed to
   specify:  (i) the aggregate principal amount of the Revolving Loans
   to be made pursuant to such Borrowing; (ii) the date of such
   Borrowing (which shall be a Business Day); and (iii) whether the
   Revolving Loans being made pursuant to such Borrowing are to be
   initially maintained as Base Rate Loans or Eurodollar Loans and,
   if Eurodollar Loans, the initial Interest Period to be applicable
   thereto.  The Agent shall promptly give each Bank notice of such
   proposed Borrowing, of such Bank's proportionate share thereof
   and of the other matters specified in the Notice of Borrowing.
   
     (b) (i)  Whenever the Borrower desires to make a Borrowing
   of Swingline Loans hereunder, it shall give Paribas not later than
   12:00 Noon (New York time) on the date that a Swingline Loan is
   to be made, written notice or telephonic notice promptly confirmed
   in writing of each Swingline Loan to be made hereunder.  Each
   such notice shall be irrevocable and specify in each case (A) the
   date of Borrowing (which shall be a Business Day) and (B) the
   aggregate principal amount of the Swingline Loans to be made
   pursuant to such Borrowing.
   
     (ii)  Mandatory Borrowings shall be made upon the notice
   specified in Section 1.01(c), with the Borrower irrevocably
   agreeing, by its incurrence of any Swingline Loan, to the making
   of the Mandatory Borrowings as set forth in Section 1.01(c).
   
     1.04  Disbursement of Funds.  No later than 12:00 Noon
   (New York time) on the date specified in each Notice of Borrowing
   (or (x) in the case of Swingline Loans, not later than 2:00 P.M.
   (New York time) on the date specified pursuant to Section
   1.03(b)(i) or (y) in the case of Mandatory Borrowings, not later
   than 12:00 Noon (New York time) on the date specified in Section
   1.01(c)), each Bank will make available its pro rata portion
   (determined in accordance with Section 1.07) of each such
   Borrowing requested to be made on such date (or in the case of
   Swingline Loans, Paribas shall make available the full amount
   thereof).  All such amounts shall be made available in Dollars and
   in immediately available funds at the Payment Office of the Agent,
   and the Agent will make available to the Borrower at the Payment
   Office in immediately available funds the aggregate of the amounts
   so made available by the Banks.  Unless the Agent shall have been
   notified by any Bank prior to the date of Borrowing that such Bank
   does not intend to make available to the Agent such Bank's portion
   of any Borrowing to be made on such date, the Agent may assume
   that such Bank has made such amount available to the Agent on
   such date of Borrowing and the Agent may, in reliance upon such
   assumption, make available to the Borrower a corresponding
   amount.  If such corresponding amount is not in fact made available
   to the Agent by such Bank, the Agent shall be entitled to recover
   such corresponding amount on demand from such Bank.  If such
   Bank does not pay such corresponding amount forthwith upon the
   Agent's demand therefor, the Agent shall promptly notify the
   Borrower and the Borrower shall immediately pay such
   corresponding amount to the Agent.  The Agent shall also be entitled to
   recover on demand from such Bank or the Borrower, as the case
   may be, interest on such corresponding amount in respect of each
   day from the date such corresponding amount was made available
   by the Agent to the Borrower until the date such corresponding
   amount is recovered by the Agent, at a rate per annum equal to (i)
   if recovered from such Bank, the overnight Federal Funds Rate and
   (ii) if recovered from the Borrower, the rate of interest applicable
   to the respective Borrowing, as determined pursuant to Section
   1.08.  Nothing in this Section 1.04 shall be deemed to relieve any
   Bank from its obligation to make Revolving Loans hereunder or to
   prejudice any rights which the Borrower may have against any Bank
   as a result of any failure by such Bank to make Revolving Loans
   hereunder.
   
     1.05  Notes.  (a)  The Borrower's obligation to pay the
   principal of, and interest on, the Loans made by each Bank shall be
   evidenced (i) if Revolving Loans, by a promissory note duly
   executed and delivered by the Borrower substantially in the form of
   Exhibit B-1, with blanks appropriately completed in conformity

   "Revolving Notes") and (ii) if Swingline Loans, by a promissory
   note duly executed and delivered by the Borrower substantially in
   the form of Exhibit B-2, with blanks appropriately completed in
   conformity herewith (the "Swingline Note").

   executed by the Borrower, (ii) be payable to the order of such Bank
   and be dated the Effective Date, (iii) be in a stated principal amount
   equal to the Revolving Loan Commitment of such Bank and be
   payable in the principal amount of the Revolving Loans evidenced
   thereby, (iv) mature on the Revolving Loan Maturity Date, (v) bear
   interest as provided in the appropriate clause of Section 1.08 in

   as provided in Section 4.01, and mandatory repayment as provided
   in Section 4.02 and (vii) be entitled to the benefits of this
   Agreement and the Security Documents.
   
     (c)  The Swingline Note issued to Paribas shall (i) be
   executed by the Borrower, (ii) be payable to the order of Paribas
   and be dated the Effective Date, (iii) be in a stated principal amount
   equal to the Maximum Swingline Amount and be payable in the
   principal amount of the outstanding Swingline Loans evidenced
   thereby from time to time, (iv) mature on the Swingline Expiry
   Date, (v) bear interest as provided in the appropriate clause of
   Section 1.08 in respect of the Base Rate Loans evidenced thereby
   and (vi) be entitled to the benefits of this Agreement and the
   Security Documents.
   
     (d)  Each Bank will note on its internal records the amount
   of each Loan made by it and each payment in respect thereof and
   will prior to any transfer of any of its Notes endorse on the reverse
   side thereof the outstanding principal amount of Loans evidenced
   thereby.  Failure to make any such notation or any error in any such
   notation shall not affect the Borrower's obligations in respect of
   such Loans.
   
     1.06  Conversions.  The Borrower shall have the option to
   convert on any Business Day all or a portion at least equal to the
   Minimum Borrowing Amount of the outstanding principal amount
   of the Revolving Loans owing by the Borrower and made pursuant
   to one or more Borrowings of one Type of Revolving Loan into a
   Borrowing or Borrowings of the other Type of Revolving Loan;
   provided that:  (i) except as otherwise provided in Section 1.10(b),
   Eurodollar Loans may be converted into Base Rate Loans only on
   the last day of an Interest Period applicable to the Loans being
   converted and no such partial conversion of Eurodollar Loans shall
   reduce the outstanding principal amount of such Eurodollar Loans
   made pursuant to a single Borrowing to less than the Minimum
   Borrowing Amount applicable thereto; (ii) Base Rate Loans may
   only be converted into Eurodollar Loans if no Default or Event of
   Default is in existence on the date of the conversion; (iii) no
   conversion pursuant to this Section 1.06 shall result in a greater
   number of Borrowings than is permitted under Section 1.02; and
   (iv) Swingline Loans may not be converted pursuant to this Section
   1.06.  Each such conversion shall be effected by the Borrower by
   giving the Agent at its Notice Office prior to 12:00 Noon (New
   York time) at least three Business Days' prior written notice (or
   telephonic notice promptly confirmed in writing) (each a "Notice of
   Conversion"), appropriately completed to specify the Loans to be
   so converted, the Borrowing(s) pursuant to which such Loans were
   made and, if to be converted into Eurodollar Loans, the Interest
   Period to be initially applicable thereto.  The Agent shall give each
   Bank prompt notice of any such proposed conversion affecting any
   of its Loans.  Upon any such conversion the proceeds thereof will
   be deemed to be applied directly on the day of such conversion to
   prepay the outstanding principal amount of the Loans being
   converted.
   
     1.07  Pro Rata Borrowings.  All Borrowings of Revolving
   Loans under this Agreement shall be incurred from the Banks pro
   rata on the basis of their respective Revolving Loan Commitments. 
   It is understood that no Bank shall be responsible for any default by
   any other Bank of its obligation to make Loans hereunder and that
   each Bank shall be obligated to make the Loans provided to be
   made by it hereunder regardless of the failure of any other Bank to
   make its Loans hereunder.
   
     1.08  Interest.  (a)  The Borrower agrees to pay interest in
   respect of the unpaid principal amount of each Base Rate Loan from
   the date of the Borrowing thereof until the maturity thereof
   (whether by acceleration or otherwise) at a rate per annum which shall
   at all times be equal to the sum of the Applicable Base Rate Margin
   plus the Base Rate in effect from time to time.
   
     (b)  The Borrower agrees to pay interest in respect of the
   unpaid principal amount of each Eurodollar Loan from the date of
   the Borrowing thereof until the maturity thereof (whether by
   acceleration or otherwise) at a rate per annum which shall, during
   each Interest Period applicable thereto, be equal to the sum of the
   Applicable Eurodollar Margin plus the Quoted Rate for such
   Interest Period.
   
     (c)  Overdue principal and, to the extent permitted by law,
   overdue interest in respect of each Loan and any other overdue
   amount payable hereunder shall, in each case, bear interest at a rate
   per annum equal to the greater of (x) the sum of (i) the Base Rate
   in effect from time to time, (ii) the Applicable Base Rate Margin for
   Base Rate Loans at such time and (iii) 2% and (y) the rate which is
   2% in excess of the rate of interest then applicable to such Loan, in
   each case with such interest to be payable on demand.
   
     (d)  Accrued (and theretofore unpaid) interest shall be
   payable:  (i) in respect of each Base Rate Loan, quarterly in arrears
   on each Quarterly Payment Date; (ii) in respect of each Eurodollar
   Loan, on the last day of each Interest Period applicable thereto and,
   in the case of an Interest Period in excess of three months, on each
   date occurring at three month intervals after the first day of such
   Interest Period; and (iii) in respect of each Loan, on any repayment
   (on the amount repaid), at maturity (whether by acceleration or
   otherwise) and, after such maturity, on demand.
   
     (e)  Upon each Interest Determination Date, the Agent shall
   determine the Quoted Rate for the Interest Period applicable to
   Eurodollar Loans and shall promptly notify the Borrower and the
   Banks thereof.  Each such determination shall, absent manifest
   error, be final and conclusive and binding on all parties hereto.
   
     1.09  Interest Periods.  At the time it gives any Notice of
   Borrowing or Notice of Conversion in respect of the making of, or
   conversion into, a Eurodollar Loan (in the case of the initial Interest
   Period applicable thereto) or prior to 12:00 Noon (New York time)
   on the third Business Day prior to the expiration of an Interest
   Period applicable to such Eurodollar Loan (in the case of any
   subsequent Interest Period), the Borrower shall have the right to
   elect, by giving the Agent notice thereof, the interest period (each
   an "Interest Period") applicable to such Eurodollar Loan, which
   Interest Period shall, at the option of the Borrower, be a one, two,
   three or six month period:
   
        (i)   all Eurodollar Loans comprising a single
        Borrowing shall at all times have the same Interest Period;
   
       (ii)   the initial Interest Period for any Eurodollar
        Loan shall commence on the date of Borrowing of such
        Loan (including the date of any conversion thereto from a
        Borrowing of Base Rate Loans) and each Interest Period
        occurring thereafter in respect of such Loan shall commence
        on the day on which the next preceding Interest Period
        applicable thereto expires;
   
      (iii)   if any Interest Period relating to a Eurodollar
        Loan begins on a day for which there is no numerically
        corresponding day in the calendar month at the end of such
        Interest Period, such Interest Period shall end on the last
        Business Day of such calendar month;
   
       (iv)   if any Interest Period would otherwise expire
        on a day which is not a Business Day, such Interest Period
        shall expire on the next succeeding Business Day; provided,
        however, that if any Interest Period for a Eurodollar Loan
        would otherwise expire on a day which is not a Business
        Day but is a day of the month after which no further
        Business Day occurs in such month, such Interest Period
        shall expire on the next preceding Business Day;
   
        (v)   no Interest Period for a Borrowing may be
        elected if it would extend beyond the Revolving Loan
        Maturity Date; and
   
       (vi)   no Interest Period may be selected while a
        Default or Event of Default exists.
   
     If upon the expiration of any Interest Period applicable to a
   Borrowing of Eurodollar Loans, the Borrower has failed to elect a
   new Interest Period to be applicable to such Eurodollar Loans as
   provided above, the Borrower shall be deemed to have elected to
   convert such Eurodollar Loans into Base Rate Loans effective as of
   the expiration date of such current Interest Period.
   
     1.10  Increased Costs, Illegality, etc.  (a)  In the event that
   any Bank shall have determined (which determination shall, absent
   manifest error, be final and conclusive and binding upon all parties
   hereto but, with respect to clause (i) below, may be made only by
   the Agent):
   
        (i)   on any Interest Determination Date that, by
        reason of any changes arising after the date of this
        Agreement affecting the interbank Eurodollar market
        generally, adequate and fair means do not exist for ascertaining
        the applicable interest rate on the basis provided for
        in the definition of Quoted Rate; or
   
       (ii)   at any time, that such Bank shall incur
        increased costs or reductions in the amounts received or
        receivable hereunder with respect to any Eurodollar Loan
        because of (x) any change since the date of this Agreement
        in any applicable law or governmental rule, regulation,
        order, guideline or request (whether or not having the force
        of law) or in the interpretation or administration thereof and
        including the introduction of any new law or governmental
        rule, regulation, order, guideline or request, such as, for
        example, but not limited to:  (A) a change in the basis of
        taxation of payments to any Bank of the principal of or
        interest on the Notes or any other amounts payable
        hereunder (except for changes in the rate of tax on, or
        determined by reference to, the net income or profits of such
        Bank imposed by the jurisdiction in which such Bank is
        organized, in which its principal office or applicable lending
        office is located) or (B) a change in official reserve
        requirements (but, in all events, excluding reserves required under
        Regulation D to the extent included in the computation of
        the Quoted Rate) and/or (y) other circumstances since the
        date of this Agreement affecting such Bank or the interbank
        Eurodollar market or the position of such Bank in such
        market; or
   
      (iii)   at any time, that the making or continuance of
        any Eurodollar Loan has been made (x) unlawful by any law
        or governmental rule, regulation or order, (y) impossible by
        compliance by any Bank in good faith with any
        governmental request (whether or not having the force of
        law) or (z) impracticable as a result of a contingency
        occurring after the date of this Agreement which materially
        and adversely affects the interbank Eurodollar market;
   
   then, and in any such event, such Bank (or the Agent, in the case
   of clause (i) above) shall promptly give notice (by telephone
   confirmed in writing) to the Borrower and, except in the case of
   clause (i) above, to the Agent of such determination (which notice
   the Agent shall promptly transmit to each of the other Banks). 
   Thereafter:  (x) in the case of clause (i) above, Eurodollar Loans
   shall no longer be available until such time as the Agent notifies the
   Borrower and the Banks that the circumstances giving rise to such
   notice by the Agent no longer exist, and any Notice of Borrowing
   or Notice of Conversion given by the Borrower with respect to
   Eurodollar Loans which have not yet been incurred (including by
   way of conversion) shall be deemed rescinded by the Borrower; (y)
   in the case of clause (ii) above, the Borrower shall pay to such
   Bank, upon written demand therefor, such additional amounts (in
   the form of an increased rate of, or a different method of calculating,
   interest or otherwise as such Bank in its sole discretion shall
   determine) as shall be required to compensate such Bank for such
   increased costs or reductions in amounts received or receivable
   hereunder (a written notice as to the additional amounts owed to
   such Bank, showing in reasonable detail the basis for the calculation
   thereof, submitted to the Borrower by such Bank shall, absent
   manifest error, be final and conclusive and binding on all the parties
   hereto); and (z) in the case of clause (iii) above, the Borrower shall
   take one of the actions specified in Section 1.10(b) as promptly as
   possible and, in any event, within the time period required by law. 
   Notwithstanding the foregoing, the failure of a Bank to give any
   notice pursuant to clause (ii) above shall not release or diminish any
   of the Borrower's obligations to pay additional amounts pursuant to
   this Section 1.10(a), provided that if any notice required by this
   Section 1.10(a) is given by any Bank more than 180 days after such
   Bank obtains knowledge of the occurrence of the event giving rise
   to the additional cost, reduction in amounts or other additional
   amounts of the type described in this Section 1.10(a), such Bank
   shall not be entitled to compensation under this Section 1.10(a) for
   any such amounts incurred prior to the 180th day prior to the giving
   of such notice to the Borrower.  
   
     (b)  At any time that any Eurodollar Loan is affected by the
   circumstances described in Section 1.10(a)(ii) or (iii), the Borrower
   may (and in the case of a Eurodollar Loan affected by the
   circumstances described in Section 1.10(a)(iii) shall) either (i) if the
   affected Eurodollar Loan is then being made initially or pursuant to
   a conversion, by giving the Agent telephonic notice (confirmed in
   writing) on the same date that the Borrower was notified by the
   affected Bank or the Agent pursuant to Section 1.10(a)(ii) or (iii),
   cancel the respective Borrowing, or (ii) if the affected Eurodollar
   Loan is then outstanding, upon at least three Business Days' written
   notice to the Agent, require the affected Bank to convert such
   Eurodollar Loan into a Base Rate Loan; provided that if more than
   one Bank is affected at any time, then all affected Banks must be
   treated the same pursuant to this Section 1.10(b).
   
     (c)  If at any time any Bank determines that the introduction
   of or any change after the date hereof in any applicable law or rule,
   regulation, order, guideline or request (whether or not having the
   force of law and including without limitation those announced or
   published prior to the Effective Date) concerning capital adequacy,
   or any change in interpretation or administration thereof by any
   governmental authority, central bank or comparable agency, has or
   would have the effect of increasing the amount of capital required
   to be maintained by such Bank based on the existence of such
   Bank's Revolving Loan Commitment hereunder or its obligations
   hereunder, then the Borrower agrees to pay to such Bank, upon its
   written demand therefor, such additional amounts as shall be
   required to compensate such Bank for the increased cost to such Bank
   or the reduction in the rate of return to such Bank as a result of
   such increase of capital.  In determining such additional amounts,
   each Bank will act reasonably and in good faith and will use
   averaging and attribution methods which are reasonable; provided
   that such Bank's determination of compensation owing under this
   Section 1.10(c) shall, absent manifest error, be final and conclusive
   and binding on all the parties hereto.  Each Bank, upon determining
   that any additional amounts will be payable pursuant to this Section
   1.10(c), will give prompt written notice thereof to the Borrower,
   which notice shall show in reasonable detail the basis for calculation
   of such additional amounts.  Notwithstanding the foregoing, the
   failure of a Bank to give any notice pursuant to the preceding
   sentence shall not release or diminish any of the Borrower's
   obligations to pay additional amounts pursuant to this Section
   1.10(c), provided that if any notice required by this Section 1.10(c)
   is given by any Bank more than 180 days after such Bank obtains
   knowledge of the occurrence of the event giving rise to the
   additional cost or reduction in amounts of the type described in this
   Section 1.10(c), such Bank shall not be entitled to compensation
   under this Section 1.10(c) for any such amounts incurred prior to
   the 180th day prior to the giving of such notice to the Borrower.  
   
     (d)  Notwithstanding any other provision of Section 1.10 or
   2.06, each Bank will, to the extent the increased costs or reductions
   in amounts receivable referred to above or in Section 2.06 relate to
   such Bank's loans, commitments or letters of credit in general and
   are not specifically attributable to a Loan, Revolving Loan
   Commitment or Letter of Credit hereunder, use averaging and
   attribution methods which cover all loans, commitments and letters
   of credit similar to the Loans, Revolving Loan Commitment or
   Letters of Credit made by such Bank in similar circumstances for
   comparable customers whether or not the loan documentation for
   such other loans, commitments or letters of credit permits the Bank
   to make the determination specified in Section 1.10 or 2.06.
   
     1.11  Compensation.  The Borrower agrees to compensate
   each Bank, upon its written request (which request shall set forth in
   reasonable detail the basis for requesting such compensation), for
   all losses, expenses and liabilities (including, without limitation, any
   loss, expense or liability incurred by reason of the liquidation or
   reemployment of deposits or other funds required by such Bank to
   fund its Eurodollar Loans) which such Bank may sustain:  (i) if for
   any reason (other than a default by such Bank or the Agent) a
   Borrowing of, or conversion from or into, Eurodollar Loans does not
   occur on a date specified therefor in a Notice of Borrowing or
   Notice of Conversion (whether or not withdrawn by the Borrower
   or deemed withdrawn pursuant to Section 1.10(a)); (ii) if any
   repayment (including any repayment made pursuant to Section 4.02)
   or conversion of any Eurodollar Loans occurs on a date which is
   not the last day of an Interest Period with respect thereto; (iii) if any
   prepayment of any Eurodollar Loans is not made on any date
   specified in a notice of prepayment given by the Borrower; or (iv)
   as a consequence of (x) any other default by the Borrower to repay
   its Eurodollar Loans when required by the terms of this Agreement
   or any Note held by such Bank or (y) any election made pursuant
   to Section 1.10(b).  A Bank's basis for requesting compensation
   pursuant to this Section and the calculations therefor shall be set
   forth in reasonable detail and shall, absent manifest error, be final
   and conclusive and binding on all the parties hereto.
   
     1.12  Change of Lending Office.  Each Bank agrees that
   upon the occurrence of any event giving rise to the operation of
   Section 1.10(a)(ii) or (iii), Section 1.10(c), Section 2.06 or Section
   4.04, with respect to such Bank, it will, if requested by the
   Borrower, use reasonable efforts (subject to overall policy
   considerations of such Bank) to designate another lending office of
   such Bank for any Loans or Letters of Credit affected by such
   event, provided that such designation is made on such terms that
   such Bank or its respective lending offices suffer no economic, legal
   or regulatory disadvantage as a result thereof, with the object of
   avoiding the consequence of the event giving rise to the operation
   of such Section.  Nothing in this Section 1.12 shall affect or
   postpone any of the obligations of the Borrower or the right of any
   Bank provided in such Sections 1.10, 2.06 or 4.04.
   
     1.13  Replacement of Banks.  (x) If any Bank becomes a
   Defaulting Bank or otherwise defaults in its obligations to make
   Loans or fund Unpaid Drawings or Mandatory Borrowings, (y) if
   any Bank refuses to consent to certain proposed changes, waivers,
   discharges or terminations with respect to this Agreement which
   have been approved by the Required Banks as provided in Section
   13.12(b) or (z) upon the occurrence of any event giving rise to the
   operation of Section 1.10(a)(ii) or (iii), Section 1.10(c), Section
   2.06 or Section 4.04, with respect to any Bank which results in
   such Bank charging to the Borrower increased costs materially in
   excess of those being generally charged by the other Banks, then the
   Borrower shall have the right, if no Default or Event of Default
   then exists, to replace such Bank (the "Replaced Bank") with any
   other Bank or with one or more Eligible Transferee or Transferees,
   none of whom shall constitute a Defaulting Bank at the time of such
   replacement (collectively, the "Replacement Bank") reasonably
   acceptable to the Agent, provided that:
   
        (i)   at the time of any replacement pursuant to this
        Section 1.13, the Replacement Bank shall enter into one or
        more assignment agreements pursuant to Section 13.04(b)
        (and with all fees payable pursuant to said Section 13.04(b)
        to be paid by the Replacement Bank) pursuant to which the
        Replacement Bank shall acquire the Revolving Loan
        Commitment and outstanding Loans of, and participations
        in Letters of Credit by, the Replaced Bank and, in
        connection therewith, shall pay to (x) the Replaced Bank in
        respect thereof an amount equal to the sum of (A) an amount
        equal to the principal of, and all accrued interest on, all
        outstanding Loans of the Replaced Bank, (B) an amount
        equal to such Replaced Bank's Percentage of all Unpaid
        Drawings that have been funded by (and not reimbursed to)
        such Replaced Bank, together with all then unpaid interest
        with respect thereto at such time and (C) an amount equal to
        all accrued, but theretofore unpaid, Fees owing to the
        Replaced Bank pursuant to Section 3.01 hereof, (y) Paribas
        an amount equal to such Replaced Bank's Percentage of any
        Unpaid Drawing (which at such time remains an Unpaid
        Drawing) to the extent such amount was not theretofore
        funded by such Replaced Bank and (z) Paribas an amount
        equal to such Replaced Bank's Percentage of any Mandatory
        Borrowing to the extent such amount was not theretofore
        funded by such Replaced Bank; and 
   
       (ii)   all obligations of the Borrower owing to the
        Replaced Bank (other than those specifically described in
        clause (i) above in respect of which the assignment purchase
        price has been, or is concurrently being, paid) shall be paid
        in full to such Replaced Bank concurrently with such
        replacement.
   
   Upon the execution of the respective assignment documentation, the
   payment of amounts referred to in clauses (i) and (ii) above and, if
   so requested by the Replacement Bank, delivery to the Replacement
   Bank of the appropriate Notes executed by the Borrower, the
   Replacement Bank shall become a Bank hereunder and the Replaced
   Bank shall cease to constitute a Bank hereunder with respect to the
   Loans and Revolving Loan Commitment so transferred, except with
   respect to indemnification provisions under this Agreement, which
   shall survive as to such Replaced Bank and (y) the Percentages of
   the Banks shall be automatically adjusted at such time to give effect
   to such replacement.
   
     Section 2.  Letters of Credit.
   
     2.01  Letters of Credit.  (a) (i) Subject to and upon the terms
   and conditions herein set forth, the Borrower may request the
   Issuing Bank, at any time and from time to time after the Effective
   Date and prior to the Revolving Loan Maturity Date to issue, for
   the account of the Borrower and for the benefit of any holder (or
   any trustee, agent or other similar representative for any such
   holders) of L/C Supportable Indebtedness of the Borrower, an
   irrevocable standby letter of credit in a form customarily used by
   the Issuing Bank or in such other form as has been approved by the
   Issuing Bank in support of said L/C Supportable Indebtedness (each
   such letter of credit, a "Letter of Credit" and collectively, the
   "Letters of Credit").  All Letters of Credit shall be denominated in
   Dollars.
   
          (ii) It is hereby acknowledged and agreed that the
        Letters of Credit described on Schedule V (the "Existing
        Letters of Credit"), which were issued under the Original
        Credit Agreement and are outstanding immediately prior to
        the Effective Date, shall be permitted to remain outstanding
        on and after the Effective Date and shall each constitute a
        Letter of Credit that is issued and outstanding under this
        Agreement for all purposes of this Agreement.
   
     (b)  The Issuing Bank hereby agrees that it will (subject to
   the terms and conditions contained herein), at any time and from
   time to time after the Effective Date and prior to the Revolving
   Loan Maturity Date, following its receipt of the respective Letter
   of Credit Request, issue for the account of the Borrower one or
   more Letters of Credit in support of such L/C Supportable
   Indebtedness of the Borrower as is permitted to remain outstanding
   without giving rise to a Default or Event of Default hereunder;
   provided that the Issuing Bank shall be under no obligation to issue
   any Letter of Credit if at the time of such issuance:
   
        (i)   any order, judgment or decree of any governmental
        authority or arbitrator shall purport by its terms to
        enjoin or restrain the Issuing Bank from issuing such Letter
        of Credit or any requirement of law applicable to the Issuing
        Bank or any request or directive (whether or not having the
        force of law) from any governmental authority with
        jurisdiction over the Issuing Bank shall prohibit, or request
        that the Issuing Bank refrain from, the issuance of letters of
        credit generally or the Letter of Credit in particular or shall
        impose upon such Issuing Bank with respect to such Letter
        of Credit any restriction or reserve or capital requirement
        (for which such Issuing Bank is not otherwise compensated)
        not in effect on the date hereof, or any unreimbursed loss,
        cost or expense which was not applicable, in effect or
        known to such Issuing Bank as of the date hereof and which
        such Issuing Bank in good faith deems material to it;
   
       (ii)   such Issuing Bank shall have received notice
        from any Bank prior to the issuance of such Letter of Credit
        of the type described in the penultimate sentence of Section
        2.03(b); or
   
      (iii)   a Bank Default exists unless the Issuing Bank
        has entered into arrangements satisfactory to it and the
        Borrower to eliminate the Issuing Bank's risk with respect
        to the Bank which is the subject of the Bank Default,
        including the cash collateralizing by the Borrower of such
        Bank's Percentage of the Letter of Credit Outstandings.
   
     (c)  Notwithstanding the foregoing, (i) no Letter of Credit
   shall be issued the Stated Amount of which, when added to the
   Letter of Credit Outstandings (exclusive of Unpaid Drawings which
   are repaid on the date of, and prior to the issuance of, the respective
   Letter of Credit) at such time, would exceed either (x) $3,000,000
   or (y) when added to the aggregate principal amount of all
   Revolving Loans then outstanding and Swingline Loans then
   outstanding, an amount equal to the lesser of (A) the Total Revolving
   Loan Commitment then in effect (after giving effect to any
   reductions to the Total Revolving Loan Commitment on such date)
   or (B) the Borrowing Base then in effect, (ii) each Letter of Credit
   shall by its terms terminate on or before the earlier of (x) the date
   which occurs 12 months after the date of the issuance thereof
   (although any such Letter of Credit may (at the sole discretion of
   the Issuing Bank) be renewable for successive periods of up to 12
   months, but not beyond the Revolving Loan Maturity Date) and (y)
   the Revolving Loan Maturity Date and (iii) no more than four
   Letters of Credit shall be outstanding at any time.
   
     2.02  Minimum Stated Amount.  The Stated Amount of each
   Letter of Credit shall be not less than $100,000 or such lesser
   amount as is acceptable to the Issuing Bank.
   
     2.03  Letter of Credit Requests.  (a)  Whenever the
   Borrower desires that a Letter of Credit be issued for its account,
   the Borrower shall give the Agent and the Issuing Bank at least five
   days' (or such shorter period as is acceptable to the Issuing Bank in
   any given case) written notice prior to the proposed date of issuance
   (which shall be a Business Day).  Each notice shall be in the form
   of Exhibit C (each a "Letter of Credit Request").  The Agent shall
   promptly transmit copies of each Letter of Credit Request to each
   Bank.
   
     (b)  The making of each Letter of Credit Request shall be
   deemed to be a representation and warranty by the Borrower that
   such Letter of Credit may be issued in accordance with, and will
   not violate the requirements of, Section 2.01(c).  Unless the Issuing
   Bank has received notice from any Bank before it issues a Letter of
   Credit that one or more of the conditions specified in Section 5 or
   6, as the case may be, are not then satisfied, or that the issuance of
   such Letter of Credit would violate Section 2.01(c), then the Issuing
   Bank may issue the requested Letter of Credit for the account of the
   Borrower in accordance with the Issuing Bank's usual and
   customary practices.  Upon its issuance of any Letter of Credit, the
   Issuing Bank shall promptly notify each Bank of such issuance,
   which notice shall be accompanied by a copy of the Letter of Credit
   actually issued.
   
     2.04  Letter of Credit Participations.  (a)  Immediately upon
   the issuance by the Issuing Bank of any Letter of Credit (or on the
   Effective Date in the case of the Existing Letters of Credit), the
   Issuing Bank shall be deemed to have sold and transferred to each
   Bank with a Revolving Loan Commitment, other than the Issuing
   Bank (each such Bank, in its capacity under this Section 2.04, a
   "Participant"), and each such Participant shall be deemed
   irrevocably and unconditionally to have purchased and received
   from the Issuing Bank, without recourse or warranty, an undivided
   interest and participation, to the extent of such Participant's
   Percentage in such Letter of Credit, each substitute letter of credit,
   each drawing made thereunder and the obligations of the Borrower
   under this Agreement with respect thereto, and any security therefor
   or guaranty pertaining thereto.  Upon any change in the Revolving
   Loan Commitments or Percentages of the Banks pursuant to Section
   13.04, it is hereby agreed that, with respect to all outstanding
   Letters of Credit and Unpaid Drawings, there shall be an automatic
   adjustment to the participations pursuant to this Section 2.04 to
   reflect the new Percentages of the assignor and assignee Bank or of
   all Banks with Revolving Loan Commitments, as the case may be.
   
     (b)  In determining whether to pay under any Letter of
   Credit, the Issuing Bank shall have no obligation relative to the
   other Banks other than to confirm that any documents required to
   be delivered under such Letter of Credit appear to have been
   delivered and that they appear to comply on their face with the
   requirements of such Letter of Credit.  Any action taken or omitted
   to be taken by the Issuing Bank under or in connection with any
   Letter of Credit if taken or omitted in the absence of gross
   negligence or willful misconduct, shall not create for the Issuing
   Bank any resulting liability to the Borrower or any Bank.
   
     (c)  In the event that the Issuing Bank makes any payment
   under any Letter of Credit and the Borrower shall not have
   reimbursed such amount in full to the Issuing Bank pursuant to
   Section 2.05(a), the Issuing Bank shall promptly notify the Agent,
   which shall promptly notify each Participant of such failure, and
   each Participant shall promptly and unconditionally pay to the
   Agent for the account of the Issuing Bank the amount of such
   Participant's Percentage of such unreimbursed payment in Dollars
   and in same day funds.  If the Agent so notifies, prior to 11:00
   A.M. (New York time) on any Business Day, any Participant
   required to fund a payment under a Letter of Credit, such
   Participant shall make available to the  Agent at the Payment Office
   of the Agent for the account of the Issuing Bank in Dollars such
   Participant's Percentage of the amount of such payment on such
   Business Day in same day funds.  If and to the extent such
   Participant shall not have so made its Percentage of the amount of
   such payment available to the Agent for the account of the Issuing
   Bank, such Participant agrees to pay to the Agent for the account of
   the Issuing Bank, forthwith on demand such amount, together with
   interest thereon, for each day from such date until the date such
   amount is paid to the Agent for the account of the Issuing Bank at
   the overnight Federal Funds Rate.  The failure of any Participant to
   make available to the Agent for the account of the Issuing Bank its
   Percentage of any payment under any Letter of Credit shall not
   relieve any other Participant of its obligation hereunder to make
   available to the Agent for the account of the Issuing Bank its
   Percentage of any Letter of Credit on the date required, as specified
   above, but no Participant shall be responsible for the failure of any
   other Participant to make available to the Agent for the account of
   the Issuing Bank such other Participant's Percentage of any such
   payment.
   
     (d)  Whenever the Issuing Bank receives a payment of a
   reimbursement obligation as to which the Agent has received for the
   account of the Issuing Bank any payments from the Participants
   pursuant to clause (c) above, the Issuing Bank shall pay to the
   Agent and the Agent shall promptly pay each Participant which has
   paid its Percentage thereof, in Dollars and in same day funds, an
   amount equal to such Participant's share (based on the proportionate
   aggregate amount funded by such Participant to the aggregate
   amount funded by all Participants) of the principal amount of such
   reimbursement obligation and interest thereon accruing after the
   purchase of the respective participations.
   
     (e)  Upon the request of any Participant, the Issuing Bank
   shall furnish to such Participant copies of any Letter of Credit
   issued by the Issuing Bank and such other documentation as may
   reasonably be requested by such Participant.
   
     (f)  The obligations of the Participants to make payments to
   the Agent for the account of the Issuing Bank with respect to Letters
   of Credit issued shall be irrevocable and not subject to any
   qualification or exception whatsoever and shall be made in accordance
   with the terms and conditions of this Agreement under all circumstances,
   including, without limitation, any of the following
   circumstances:
   
        (i)   any lack of validity or enforceability of this
        Agreement or any of the Credit Documents;
   
       (ii)   the existence of any claim, setoff, defense or
        other right which the Borrower may have at any time against
        a beneficiary named in a Letter of Credit, any transferee of
        any Letter of Credit (or any Person for whom any such
        transferee may be acting), the Agent, any Participant, or any
        other Person, whether in connection with this Agreement,
        any Letter of Credit, the transactions contemplated herein or
        any unrelated transactions (including any underlying
        transaction between the Borrower and the beneficiary named
        in any such Letter of Credit);
   
      (iii)   any draft, certificate or any other document
        presented under any Letter of Credit proving to be forged,
        fraudulent, invalid or insufficient in any respect or any
        statement therein being untrue or inaccurate in any respect;
   
       (iv)   the surrender or impairment of any security
        for the performance or observance of any of the terms of
        any of the Credit Documents; or
   
        (v)   the occurrence of any Default or Event of
        Default.
   
     2.05  Agreement to Repay Letter of Credit Drawings. 
   (a)  The Borrower hereby agrees to reimburse the Issuing Bank, by
   making payment to the Agent in immediately available funds at the
   Payment Office (or by making payment directly to the Issuing Bank
   at such location as may otherwise have been agreed upon by the
   Borrower and the Issuing Bank), for any payment or disbursement
   made by the Issuing Bank under any Letter of Credit (each such
   amount so paid until reimbursed, an "Unpaid Drawing"),
   immediately after, and in any event on the date of, such payment or
   disbursement, with interest on the amount so paid or disbursed by
   the Issuing Bank, to the extent not reimbursed prior to 12:00 Noon
   (New York time) on the date of such payment or disbursement,
   from and including the date paid or disbursed to but excluding the
   date the Issuing Bank is reimbursed by the Borrower therefor at a
   rate per annum which shall be (x) unless a Borrower Bankruptcy
   Default exists on the date of the respective payment or
   disbursement, for the period from and including the date of the
   respective payment or disbursement until the earlier to occur of a
   Borrower Bankruptcy Default or the date of receipt by the Borrower
   from the Issuing Bank or the Agent of written or telephonic notice
   (as long as such notice is received by the Borrower prior to 2:00
   P.M. (New York time) on a Business Day, otherwise the Business
   Day following receipt by the Borrower of such notice) of such
   payment or disbursement, the Base Rate in effect from time to time
   plus the Applicable Base Rate Margin at such time, and (y) from
   and including the date of the respective payment or disbursement if
   a Borrower Bankruptcy Default then exists or, if a Borrower
   Bankruptcy Default does not exist on the date of the respective
   payment or disbursement, from and including the earlier to occur
   of the date upon which a Borrower Bankruptcy Default subse-
   
   quently occurs or the date of receipt by the Borrower from the
   Issuing Bank or the Agent of written or telephonic notice (as long
   as such notice is received by the Borrower prior to 2:00 P.M. (New
   York time) on a Business Day, otherwise the Business Day
   following receipt by the Borrower of such notice) of such payment
   or disbursement to but excluding the date the Issuing Bank was
   reimbursed by the Borrower therefor, equal to the sum of (i) the
   Base Rate in effect from time to time, (ii) the Applicable Base Rate
   Margin at such time and (iii) 2%, in each case with such interest to
   be payable on demand.
   
     (b)  The obligations of the Borrower under this Section 2.05
   to reimburse the Issuing Bank with respect to Unpaid Drawings
   (including, in each case, interest thereon) shall be absolute and
   unconditional under any and all circumstances and irrespective of
   any setoff, counterclaim or defense to payment which the Borrower
   may have or have had against any Bank (including in its capacity as
   Issuing Bank or as Participant), including, without limitation, any
   defense based upon the failure of any drawing under a Letter of
   Credit (each a "Drawing") to conform to the terms of the Letter of
   Credit or any nonapplication or misapplication by the beneficiary of
   the proceeds of such Drawing; provided, however, that the
   Borrower shall not be obligated to reimburse the Issuing Bank for
   any wrongful payment made by the Issuing Bank under a Letter of
   Credit as a result of acts or omissions constituting willful
   misconduct or gross negligence on the part of the Issuing Bank.
   
     2.06  Increased Costs.  If at any time after the date hereof
   the Issuing Bank or any Participant determines that the introduction
   of or any change in any applicable law, rule, regulation, order,
   guideline or request (including, without limitation, those announced
   or published prior to the Effective Date) or any change in the
   interpretation or administration thereof by any governmental
   authority or central bank charged with the interpretation or
   administration thereof, or compliance by the Issuing Bank or any
   Participant with any request or directive by any such authority
   (whether or not having the force of law), shall either (i) impose,
   modify or make applicable any reserve, deposit, capital adequacy
   or similar requirement against letters of credit issued by the Issuing
   Bank or participated in by any Participant, or (ii) impose on the
   Issuing Bank or any Participant any other conditions relating,
   directly or indirectly, to this Agreement or any Letter of Credit; and
   the result of any of the foregoing is to increase the cost to the
   Issuing Bank or any Participant of issuing, maintaining or participating
   in any Letter of Credit, or reduce the amount of any sum
   received or receivable by the Issuing Bank or any Participant
   hereunder or reduce the rate of return on its capital with respect to
   Letters of Credit, then, upon demand to the Borrower by the Issuing
   Bank or any Participant (a copy of which demand shall be sent by
   the Issuing Bank or such Participant to the Agent), the Borrower
   shall be obligated to pay to the Issuing Bank or such Participant
   such additional amount or amounts as will compensate such Bank
   for such increased cost or reduction in the amount receivable or
   reduction on the rate of return on its capital.  A certificate submitted
   to the Borrower by the Issuing Bank or such Participant (a copy of
   which certificate shall be sent by the Issuing Bank or such
   Participant to the Agent), setting forth in reasonable detail the basis
   for the calculation of such additional amount or amounts necessary
   to compensate the Issuing Bank or such Participant shall, absent
   manifest error, be final, conclusive and binding on the Borrower.
   
   
     Section 3.  Commitment Commission; Fees; Reductions of
   Commitment.
   
     3.01  Fees.  (a)  The Borrower agrees to pay the Agent for
   distribution to each Bank a commitment commission (the
   "Commitment Commission") for the period from the Effective Date
   to but excluding the Revolving Loan Maturity Date (or such earlier
   date as the Total Revolving Loan Commitment shall have been
   terminated), computed at a rate for each day equal to 1/2 of 1% per
   annum on the Unutilized Revolving Loan Commitment of such
   Bank.  Accrued Commitment Commission shall be due and payable
   quarterly in arrears on each Quarterly Payment Date and on the
   Revolving Loan Maturity Date or such earlier date upon which the
   Total Revolving Loan Commitment is terminated.
   
     (b)  The Borrower agrees to pay to the Issuing Bank, for its
   own account, a facing fee in respect of each Letter of Credit issued
   by the Issuing Bank hereunder (the "Facing Fee"), for the period
   from and including the date of issuance of such Letter of Credit (or
   from and including the Effective Date in the case of the Existing
   Letter of Credit) to and including the termination of such Letter of
   Credit, in an amount equal to 1/8 of 1% per annum of the daily
   average Stated Amount of such Letters of Credit. Accrued Facing
   Fees shall be due and payable quarterly in arrears on each Quarterly
   Payment Date and the date of the termination of the Total Revolving
   Loan Commitment on which no Letters of Credit remain
   outstanding.
   
     (c)  The Borrower agrees to pay to the Agent for distribution
   to each Bank a fee in respect of each Letter of Credit issued
   hereunder (the "Letter of Credit Fee"), for the period from and
   including the date of issuance of such Letter of Credit (or from and
   including the Effective Date in the case of the Existing Letters of
   Credit) (with each renewal of such Letter of Credit, for purposes of
   this Section 3.01(c) being deemed to be the issuance of a new Letter
   of Credit) to and including the termination of such Letter of Credit,
   computed on the average daily Stated Amount of such Letter of
   Credit at a rate per annum equal to the Applicable L/C Percentage
   in effect from time to time.  Letter of Credit Fees shall be
   distributed by the Agent to the Banks on the basis of their respective
   Percentages as in effect from time to time.  Accrued Letter of
   Credit Fees shall be due and payable quarterly in arrears on each
   Quarterly Payment Date and on the date of the termination of the
   Total Revolving Loan Commitment on which no Letters of Credit
   remain outstanding.
   
     (d)  The Borrower shall pay to the Issuing Bank for its own
   account upon each drawing under, issuance of, or amendment to,
   any Letter of Credit such amount as shall at the time thereof be the
   administrative charge which the Issuing Bank is generally imposing
   on similarly situated credits in connection with drawings on
   (including wire charges), issuances of, or amendments to, standby
   letters of credit.
   
     (e)  The Borrower agrees to pay to the Agent for its own
   account such other fees as have been agreed to in writing between
   the Agent and the Borrower or its Affiliates.
   
     3.02  Voluntary Termination of Unutilized Commitments. 
   Upon at least two Business Days' prior written notice (or telephonic
   notice confirmed in writing) to the Agent at its Notice Office (which
   notice the Agent shall promptly transmit to each of the Banks), the
   Borrower, shall have the right, without premium or penalty, to
   terminate the Total Unutilized Revolving Loan Commitment, in
   whole or in part, provided that (i) each such reduction shall apply
   proportionately to permanently reduce the Revolving Loan
   Commitment of each Bank and (ii) the reduction to the Total Unutilized
   Revolving Loan Commitment shall in no case be in an amount
   which would cause the Revolving Loan Commitment of any Bank
   to be reduced (as required by preceding clause (i)) by an amount
   which exceeds the remainder of (x) the Unutilized Revolving Loan
   Commitment of such Bank as in effect immediately before giving
   effect to such reduction minus (y) such Bank's Percentage of the
   aggregate principal amount of Swingline Loans then outstanding.
   
     3.03  Mandatory Reduction of Commitments.  (a)  The Total
   Revolving Loan Commitment (and the Revolving Loan
   Commitment of each Bank) shall terminate on the Revolving Loan
   Maturity Date.
   
     (b)  In addition to any other mandatory commitment
   reductions pursuant to this Section 3.03, on the date on which a
   Senior Notes Change of Control occurs, the Total Revolving Loan
   Commitment (and the Revolving Loan Commitment of each Bank)
   shall be reduced to zero.
   
   
     Section 4.  Prepayments; Payments; Taxes.
   
     4.01  Voluntary Prepayments.  The Borrower shall have the
   right to prepay Loans, without premium or penalty in whole or in
   part from time to time on the following terms and conditions:  (i)
   the Borrower shall give the Agent prior to 12:00 Noon (New York
   time) at its Notice Office at least three Business Days' prior written
   notice in the case of Eurodollar Loans and one Business Day's prior
   written notice in the case of Base Rate Loans of the Borrower's
   intent to prepay the Loans (or same day notice in the case of
   Swingline Loans provided such notice is given prior to 12:00 noon
   (New York time)), whether such Loans are Revolving Loans or
   Swingline Loans, the amount of such prepayment and the Types of
   Loans to be prepaid and, in the case of Eurodollar Loans, the
   specific Borrowing or Borrowings pursuant to which made, which
   notice the Agent shall promptly transmit to each of the Banks; (ii)
   each prepayment shall be in an aggregate principal amount of at
   least the Minimum Borrowing Amount; provided that partial
   prepayments of Eurodollar Loans need not be in an amount at least
   equal to the Minimum Borrowing Amount but must be in an amount
   at least equal to $1,000,000, no partial prepayment of Eurodollar
   Loans made pursuant to any Borrowing shall reduce the outstanding
   Eurodollar Loans made pursuant to such Borrowing to an amount
   less than the Minimum Borrowing Amount applicable thereto; (iii)
   prepayments of Eurodollar Loans made pursuant to this Section
   4.01 may only be made on the last day of an Interest Period
   applicable thereto; and (iv) each prepayment in respect of any Loans
   made pursuant to a Borrowing shall be applied pro rata among such
   Loans.
   
     4.02  Mandatory Repayments.
   
     (A)  Requirements:
   
     (a)   Subject to and in accordance with Section 4.02(A)(b),
   on any day on which the sum of the aggregate outstanding principal
   amount of Revolving Loans, Swingline Loans and Letter of Credit
   Outstandings exceeds the Total Revolving Loan Commitment as
   then in effect, the Borrower shall prepay the principal of Swingline
   Loans and, after the Swingline Loans have been repaid in full,
   Revolving Loans in an amount equal to such excess.  If, after giving
   effect to the prepayment of all outstanding Swingline Loans and
   Revolving Loans, the Letter of Credit Outstandings exceed the
   Total Revolving Loan Commitment as then in effect, the Borrower
   shall pay to the Agent at its Payment Office on such date an amount
   of cash or Cash Equivalents equal to the amount of such excess,
   such cash or Cash Equivalents to be held as security for all
   Obligations of the Borrower to the Banks hereunder in a cash collateral
   account to be established and maintained (including the investments
   made pursuant thereto) by the Agent pursuant to a cash collateral
   agreement in form and substance satisfactory to the Agent.
   
     (b)  If any Borrowing Base Certificate shall disclose the
   existence of a Borrowing Base Deficiency, the Borrower shall,
   within one Business Day after the delivery thereof in accordance
   with Section 8.01(j), (i) prepay the principal of Swingline Loans in
   an amount equal to such Borrowing Base Deficiency, (ii) after the
   Swingline Loans have been repaid in full, prepay the principal of
   Revolving Loans in an amount equal to any remaining Borrowing
   Base Deficiency and (iii) to the extent such Borrowing Base
   Deficiency exceeds the principal amount of Swingline Loans and
   Revolving Loans prepaid pursuant to the preceding clauses (i) and
   (ii), pay an amount of cash or Cash Equivalents equal to such
   excess (up to a maximum amount equal to the Letter of Credit
   Outstandings at such time) to the Agent at the Payment Office, such
   cash or Cash Equivalents to be held as security for all Obligations
   of the Borrower hereunder in a cash collateral account established
   and maintained (including the investments made pursuant thereto)
   by the Agent pursuant to a cash collateral agreement in form and
   substance satisfactory to the Agent.  
   
     (c)  In addition to any other mandatory repayments pursuant
   to this Section 4.02(A), on the Business Day after the receipt
   thereof by the Borrower, an amount equal to (i) 100% of the cash
   proceeds (net of underwriting discounts and commissions and other
   reasonable costs associated therewith) from any sale or issuance of
   equity of the Borrower (other than proceeds received from grants
   or sales of common stock of the Borrower (including as a result of
   the exercise of options or warrants) to management or key
   employees of the Borrower pursuant to any employee stock option
   plan or stock purchase plan ("Employee Stock Proceeds"), provided
   that Employee Stock Proceeds shall not be required to be repaid on
   the date of the receipt thereof (unless such date of receipt is also a
   date specified below) but instead shall be required to be repaid on
   each date on which the aggregate amount of such Employee Stock
   Proceeds received during the period commencing on the later of (x)
   the Effective Date and (y) the immediately preceding date on which
   a mandatory repayment was made pursuant to this Section
   4.02(A)(c) as a result of the receipt of Employee Stock Proceeds
   and ending on the date of determination (the "Employee Stock
   Proceeds Payment Period") equals or exceeds $250,000, with the
   amount of the repayments required on each such date to equal 100%
   of the aggregate amount of Employee Stock Proceeds received on
   or before such date during the applicable Employee Stock Proceeds
   Payment Period) and (ii) 100% of the proceeds (net of underwriting
   discounts and commissions and other reasonable costs associated
   therewith) from any incurrence of any Indebtedness by the
   Borrower (other than Indebtedness permitted by Section 9.05 as said
   Section is in effect on the Effective Date), shall be applied as
   provided in Section 4.02(B).
   
     (d)  In addition to any other mandatory repayments pursuant
   to this Section 4.02(A), on each date after the Effective Date on
   which the Borrower receives proceeds from any sale of assets
   (including capital stock and securities other than capital stock the
   proceeds from the sale of which are recaptured under Section
   4.02(A)(c) (or will be recaptured once the $250,000 threshold set
   forth in Section 4.02(A)(c) is achieved) but excluding (i) sales of
   inventory in the ordinary course of business, (ii) sales of equipment
   which, in the reasonable judgment of the Borrower have become
   obsolete, worn out or uneconomic, in the ordinary course of
   business, the proceeds of which are used, or irrevocably committed,
   to purchase replacement equipment within 60 days from the date of
   sale so long as the aggregate amount of Net Sale Proceeds excluded
   pursuant to this clause (ii) does not exceed $250,000 in the aggregate
   in any fiscal year of the Borrower, (iii) trade-ins of equipment
   by the Borrower permitted to be made in accordance with Section

   clause (iv) only) that the aggregate proceeds therefrom (the "Asset
   Sale Proceeds") shall not be required to be repaid on the date of
   receipt thereof (unless such date of receipt is also a date specified
   below) but instead shall be required to be repaid on each date on
   which the aggregate amount of such Asset Sale Proceeds received
   during the period commencing on the later of (x) the Effective Date
   and (y) the immediately preceding date on which a principal
   repayment was made pursuant to this Section 4.02(A)(d) as a result
   of the receipt of Asset Sale Proceeds and ending on the date of
   determination (the "Asset Sale Proceeds Payment Period") equals
   or exceeds $250,000, with the amount of the repayments required
   on each such date to equal 100% of the aggregate amount of Asset
   Sale Proceeds received on or before such date during the applicable
   Asset Sale Proceeds Payment Period) an amount equal to 100% of
   the Net Sale Proceeds thereof shall be applied as provided in
   Section 4.02(B).
   
     (e)  In addition to any other mandatory repayments pursuant
   to this Section 4.02(A), on the date of the receipt thereof by the
   Borrower, an amount equal to 100% of the proceeds of any
   Recovery Event (net of reasonable costs incurred in connection with
   such Recovery Event (including the estimated marginal increase in
   income taxes which will be payable as a result of such Recovery
   Event)) shall be applied as provided in Section 4.02(B); provided
   that, so long as there shall not exist a Default or an Event of
   Default, proceeds from Recovery Events (other than proceeds from
   Key-Man Life Insurance) not in excess of (x) $1,000,000 for any
   one occurrence and (y) $3,000,000 for all occurrences after the
   Effective Date and prior to the date on which there are no
   outstanding Obligations shall not be required to be so applied on
   such date to the extent that the Borrower delivers a certificate to the
   Agent on or prior to such date stating that such proceeds shall be
   used to replace or restore any properties or assets in respect of
   which such proceeds were paid within a period specified in such
   certificate not to exceed 120 days after the date of receipt of such
   proceeds (which certificate shall set forth estimates of the proceeds
   to be so expended); and provided further, that if all or any portion
   of such proceeds not so applied to the repayment of the Loans are
   not so used within the period specified in the relevant certificate
   furnished pursuant to the preceding proviso, such remaining portion
   shall be applied on the last day of such specified period as provided
   in Section 4.02(B).
   
     (f)  If a Bank Default exists, the Borrower shall, within one
   Business Day after the Borrower shall have received notice thereof,
   pay an amount of cash or Cash Equivalents equal to the Percentage
   of the Letter of Credit Outstandings and Swingline Loans then
   outstanding of the Bank which is the subject of such Bank Default
   to the Agent at the Payment Office, such cash or Cash Equivalents
   to be held as security for such Bank's Percentage of the Letter of
   Credit Outstandings and Swingline Loans then outstanding in a cash
   collateral account established and maintained (including the
   investments made pursuant thereto) by the Agent on a basis
   satisfactory to the Agent; provided that such amounts shall, so long
   as no Default or Event of Default then exists, be released at such
   time as such Bank Default shall cease to exist.
   
     (g)  Notwithstanding anything to the contrary contained
   elsewhere in this Agreement, (i) all then outstanding Swingline
   Loans shall be repaid in full on the Swingline Expiry Date and (ii)
   all then outstanding Revolving Loans shall be repaid in full on the
   Revolving Loan Maturity Date.
   
     (B)  Application:
   
     (a)  Each mandatory repayment of Loans pursuant to Section
   4.02(A)(c) through (e) shall be applied:  
   
        (i)   first, to prepay the principal of outstanding
        Swingline Loans;
   
       (ii)   second, to prepay the principal of outstanding
        Revolving Loans; and
   
      (iii)   third, to cash collateralize Letter of Credit
        Outstandings by depositing cash in a cash collateral account
        to be established and maintained by the Agent pursuant to a
        cash collateral agreement in form and substance satisfactory
        to the Agent in an amount equal to such Letter of Credit
        Outstandings.
   
     (b)  With respect to each repayment of Loans required by
   this Section 4.02, the Borrower may designate the Types of Loans
   which are to be repaid and, in the case of Eurodollar Loans, the
   specific Borrowing or Borrowings pursuant to which made;
   provided that:  (i) repayments of Eurodollar Loans pursuant to this
   Section 4.02 may only be made on the last day of an Interest Period
   applicable thereto unless all Eurodollar Loans with Interest Periods
   ending on such date of required repayment and all Base Rate Loans
   have been paid in full; (ii) if any repayment of Eurodollar Loans
   made pursuant to a single Borrowing shall reduce the outstanding
   Eurodollar Loans made pursuant to such Borrowing to an amount
   less than the applicable Minimum Borrowing Amount, such
   Borrowing shall immediately be converted into Base Rate Loans;
   and (iii) each repayment of any Loans made pursuant to a single
   Borrowing shall be applied pro rata among such Loans.  In the
   absence of a designation by the Borrower as described in the
   preceding sentence, the Agent shall, subject to the above, make such
   designation in its sole discretion.  Notwithstanding the foregoing
   provisions of this Section 4.02, if at any time the mandatory
   prepayment of Revolving Loans pursuant to Section 4.02(A)(c)
   through (e) above would result, after giving effect to the procedures
   set forth above, in the Borrower incurring breakage costs under
   Section 1.11 as a result of Eurodollar Loans being prepaid other
   than on the last day of an Interest Period applicable thereto (the
   "Affected Eurodollar Loans"), then the Borrower may in its sole
   discretion initially deposit a portion (up to 100%) of the amounts
   that otherwise would have been paid in respect of the Affected
   Eurodollar Loans with the Agent (which deposit must be equal in
   amount to the amount of Affected Eurodollar Loans not
   immediately prepaid) to be held as security for the obligations of the
   Borrower hereunder pursuant to a cash collateral agreement to be
   entered into in form and substance satisfactory to the Agent, with
   such cash collateral to be directly applied upon the first occurrence
   (or occurrences) thereafter of the last day of an Interest Period
   applicable to the relevant Eurodollar Loans (or such earlier date or
   dates as shall be requested by the Borrower), to repay an aggregate
   principal amount of Revolving Loans equal to the Affected
   Eurodollar Loans not initially repaid pursuant to this sentence;
   provided, however, such cash collateral must be applied to repay
   Revolving Loans (whether or not the Borrower would incur
   breakage costs (which the Borrower shall be responsible for), (x) in
   the case of cash collateral arising pursuant to Sections 4.02(A)(c)
   (other than from Employee Stock Proceeds) or 4.02(A)(d), no later
   than 29 days after receipt thereof and (y) in the case of cash
   collateral arising pursuant to Section 4.02(A)(c) as a result of the
   receipt of Employee Stock Proceeds or pursuant to Section
   4.02(A)(e) no later than 89 days after receipt thereof. 
   Notwithstanding anything to the contrary contained in the
   immediately preceding sentence, all amounts deposited as cash
   collateral pursuant to the immediately preceding sentence shall be
   held for the sole benefit of the Banks whose Revolving Loans would
   otherwise have been immediately repaid with the amounts deposited
   and upon the taking of any action by the Agent or the Banks
   pursuant to the remedial provisions of Section 10, any amounts held
   as cash collateral pursuant to this Section 4.02(B)(b) shall, subject
   to the requirements of applicable law, be immediately applied to the
   Revolving Loans.
   
     4.03  Method and Place of Payment.  Except as otherwise
   specifically provided herein, all payments under this Agreement or
   any Note shall be made to the Agent for the account of the Bank or
   Banks entitled thereto not later than 12:00 Noon (New York time)
   on the date when due and shall be made in Dollars in immediately
   available funds at the Payment Office of the Agent.  Whenever any
   payment to be made hereunder or under any Note shall be stated to
   be due on a day which is not a Business Day, the due date thereof
   shall be extended to the next succeeding Business Day and, with
   respect to payments of principal, interest shall be payable at the
   applicable rate during such extension.
   
     4.04  Net Payments.  (a)  All payments made by the
   Borrower hereunder or under any Note will be made without setoff,
   counterclaim or other defense.  Except as provided in Section
   4.04(b), all such payments will be made free and clear of, and
   without deduction or withholding for, any present or future taxes,
   levies, imposts, duties, fees, assessments or other charges of
   whatever nature now or hereafter imposed by any jurisdiction or by
   any political subdivision or taxing authority thereof or therein with
   respect to such payments (but excluding, except as provided in the
   second succeeding sentence, any tax imposed on or measured by the
   net income or profits of a Bank pursuant to the laws of the jurisdiction
   in which it is organized or the jurisdiction in which the
   principal office or applicable lending office of such Bank is located
   or any subdivision thereof or therein) and all interest, penalties or
   similar liabilities with respect thereto (all such non-excluded taxes,
   levies, imposts, duties, fees, assessments or other charges being
   referred to collectively as "Taxes").  If any Taxes are so levied or
   imposed, the Borrower agrees to pay the full amount of such Taxes,
   and such additional amounts as may be necessary so that every
   payment of all amounts due under this Agreement or under any
   Note, after withholding or deduction for or on account of any
   Taxes, will not be less than the amount provided for herein or in
   such Note.  If any amounts are payable in respect of Taxes pursuant
   to the preceding sentence, the Borrower agrees to reimburse each
   Bank, upon the written request of such Bank, for taxes imposed on
   or measured by the net income or profits of such Bank pursuant to
   the laws of the jurisdiction in which the principal office or applicable
   lending office of such Bank is located or under the laws of any
   political subdivision or taxing authority of any such jurisdiction in
   which the principal office or applicable lending office of such Bank
   is located and for any withholding of income or similar taxes
   imposed by the United States of America as such Bank shall
   determine are payable by, or withheld from, such Bank in respect
   of such amounts so paid to or on behalf of such Bank pursuant to
   the preceding sentence and in respect of any amounts paid to or on
   behalf of such Bank pursuant to this sentence.  The Borrower will
   furnish to the Agent within 45 days after the date the payment of
   any Taxes is due pursuant to applicable law certified copies of tax
   receipts evidencing such payment by the Borrower.  The Borrower
   agrees to indemnify and hold harmless each Bank, and reimburse
   such Bank upon its written request, for the amount of any Taxes so
   levied or imposed and paid by such Bank.
   
     (b)  Each Bank that is not a United States person (as such
   term is defined in Section 7701(a)(30) of the Code) agrees to deliver
   to the Borrower and the Agent on or prior to the Effective Date, or
   in the case of a Bank that is an assignee or transferee of an interest
   under this Agreement pursuant to Section 1.13 or 13.04 (unless the
   respective Bank was already a Bank hereunder immediately prior to
   such assignment or transfer), on the date of such assignment or
   transfer to such Bank, (i) two accurate and complete original signed
   copies of Internal Revenue Service Form 4224 or 1001 (or
   successor forms) dated the Effective Date or the date of such
   assignment or transfer, as the case may be, certifying to such
   Bank's entitlement to a complete exemption from United States
   withholding tax with respect to payments to be made under this
   Agreement and under any Note, or (ii) if the Bank is not a "bank"
   within the meaning of Section 881(c)(3)(A) of the Code and cannot
   deliver either Internal Revenue Service Form 1001 or 4224 pursuant
   to clause (i) above, (x) a certificate substantially in the form of
   Exhibit D (any such certificate, a "Section 4.04(b)(ii) Certificate")
   and (y) two accurate and complete original signed copies of Internal
   Revenue Service Form W-8 (or successor form) certifying to such
   Bank's entitlement to a complete exemption from United States
   withholding tax with respect to payments of interest to be made
   under this Agreement and under any Note.  In addition, each Bank
   agrees that from time to time after the Effective Date, when a lapse
   in time or change in circumstances renders the previous certification
   obsolete or inaccurate in any material respect, it will deliver to the
   Borrower and the Agent two new accurate and complete original
   signed copies of Internal Revenue Service Form 4224 or 1001, or
   Form W-8 and a Section 4.04(b)(ii) Certificate, as the case may be,
   and such other forms as may be required in order to confirm or
   establish the entitlement of such Bank to a continued exemption
   from or reduction in United States withholding tax with respect to
   payments under this Agreement and any Note, or it shall
   immediately notify the Borrower and the Agent of its inability to
   deliver any such Form or Certificate.  Notwithstanding anything to
   the contrary contained in Section 4.04(a), but subject to Section
   13.04(c) and the immediately succeeding sentence, (x) the Borrower
   shall be entitled, to the extent it is required to do so by law, to
   deduct or withhold income or similar taxes imposed by the United
   States (or any political subdivision or taxing authority thereof or
   therein) from interest, fees or other amounts payable hereunder for
   the account of any Bank which is not a United States person (as
   such term is defined in Section 7701(a)(30) of the Code) for U.S.
   Federal income tax purposes to the extent that such Bank has not
   provided to the Borrower U.S. Internal Revenue Service Forms that
   establish a complete exemption from such deduction or withholding
   and (y) the Borrower shall not be obligated pursuant to Section
   4.04(a) hereof to gross-up payments to be made to a Bank in respect
   of income or similar taxes imposed by the United States if (I) such
   Bank has not provided to the Borrower the Internal Revenue Service
   Forms required to be provided to the Borrower pursuant to this
   Section 4.04(b) or (II) in the case of a payment, other than interest,
   to a Bank described in clause (ii) above, to the extent that such
   forms do not establish a complete exemption from withholding of
   such taxes.  Notwithstanding anything to the contrary contained in
   the preceding sentence or elsewhere in this Section 4.04 and except
   as set forth in Section 13.04(c), the Borrower agrees to pay
   additional amounts and to indemnify each Bank in the manner set
   forth in Section 4.04(a) (without regard to the identity of the
   jurisdiction requiring the deduction or withholding) in respect of
   any amounts deducted or withheld by it as described in the
   immediately preceding sentence as a result of any changes after the
   Effective Date or, in the case of an assignee or transferee pursuant
   to Section 1.13 or 13.04, after the date of such assignment or
   transfer in any applicable law, treaty, governmental rule,
   regulation, guideline or order, or in the interpretation thereof,
   relating to the deducting or withholding of income or similar Taxes.
   
     (c)  If any taxes imposed on any Bank are paid or
   indemnified against by the Borrower under this Section 4.04, and
   such Bank receives a refund of any amount of taxes paid or
   reimbursed by such Borrower, such Bank shall pay to such
   Borrower an amount equal to the reduction in taxes due and payable
   by such Bank attributable to the amount of such refund; provided,
   however, that (x) no Bank is under any obligation to seek a refund
   of such taxes and (y) determinations as to whether a Bank has
   received a tax refund and the amount thereof shall be in the sole
   discretion of such Bank.
   
   
     Section 5.  Conditions Precedent to Credit Events on the
   Initial Borrowing Date.  The obligation of each Bank to make Loans
   (if any) on the Initial Borrowing Date and the obligation of the

   with the repayment of such Refinanced Indebtedness and all Liens

   Agreement, assigned or amended) (and all appropriate releases,
   termination statements or other instruments of amendment or
   assignment with respect thereto shall have been obtained) to the
   satisfaction of the Agent and the Required Banks.  The Agent shall
   have received copies, certified as true and complete by an
   appropriate officer of the Borrower of all documents executed in

   and product liability and regulatory matters with respect to the
   Borrower.
   
   
     Section 6.  Conditions Precedent to All Credit Events.  The
   obligation of each Bank to make Loans (including Loans on the
   Initial Borrowing Date) and the obligation of the Issuing Bank to
   permit the Existing Letters of Credit to remain outstanding on the
   Effective Date and to issue any other Letter of Credit, is subject, at
   the time of each such Credit Event (except as hereinafter indicated),
   to the satisfaction of the following conditions:
   
     6.01  No Default; Representations and Warranties.  At the
   time of each such Credit Event and also after giving effect thereto
   (i) there shall exist no Default or Event of Default and (ii) all
   representations and warranties contained herein and in the other
   Credit Documents shall be true and correct in all material respects
   with the same effect as though such representations and warranties
   had been made on the date of the making of such Credit Event (it
   being understood and agreed that any representation or warranty
   which by its terms is made as of a specified date shall be required
   to be true and correct in all material respects only as of such
   specified date).
   
     6.02  Adverse Change, etc.  At the time of each such Credit
   Event, nothing shall have occurred (and the Banks shall have
   become aware of no facts or conditions not previously known) since
   December 31, 1995 which the Agent or the Required Banks shall
   determine (i) could reasonably be expected to have a material
   adverse effect on the rights or remedies of the Banks or the Agent,
   or on the ability of the Borrower to perform its obligations to the
   Banks under this Agreement or any other Credit Document or (ii)
   which could reasonably be expected to have a Material Adverse
   Effect.
   
     6.03  Litigation.  (a) At the time of each such Credit Event
   and also after giving effect thereto, no action, suit or proceeding by
   any entity (private or governmental) shall be pending or, to the best

   Agreement or any other Document or the transactions contemplated
   hereby or which could reasonably be expected to have a Material
   Adverse Effect.
   
     (b)  At the time of each such Credit Event and also after
   giving effect thereto, no material investigation by any governmental
   entity (including, without limitation, the DHHS or any agency of
   the State of California or any other state, but excluding legislative
   and regulatory investigations and proceedings relating to the clinical
   laboratory industry in general which could not reasonably be
   expected to have a Material Adverse Effect) with respect to the
   business practices or procedures of the Borrower (including,
   without limitation, sales and marketing, pricing and billing
   practices) shall be pending or, to the best knowledge of the
   Borrower, threatened.
   
     6.04  Notice of Borrowing; Letter of Credit Request.  (a) 
   Prior to the making of each Loan (excluding Swingline Loans and
   Mandatory Borrowings), the Agent shall have received a Notice of
   Borrowing meeting the requirements of Section 1.03.  Prior to the
   making of any Swingline Loan, Paribas shall have received the
   notice required by Section 1.03(b)(i).
   
     (b)  Prior to the issuance of each Letter of Credit, the
   Issuing Bank shall have received a Letter of Credit Request meeting
   the requirements of Section 2.03.
   
     The acceptance of the benefits of each Credit Event shall
   constitute a representation and warranty by the Borrower to each of
   the Banks that all the conditions specified in this Section 6 (and with
   respect to each Credit Event occurring on the Initial Borrowing
   Date, the conditions specified in Section 5) exist as of that time. 
   All of the Notes, certificates, legal opinions and other documents
   and papers referred to in Section 5 and in this Section 6, unless
   otherwise specified, shall be delivered to the Agent at the Notice
   Office for the account of each of the Banks and, except for the
   Notes, in sufficient counterparts for each of the Banks and, unless
   otherwise specified, shall be in form and substance satisfactory to
   the Banks.
   
     Section 7.  Representations, Warranties and Agreements. 
   In order to induce the Banks to enter into this Agreement and to
   make the Loans, and issue (or participate in) the Letters of Credit
   as provided herein, the Borrower makes the following representations,
   warranties and agreements, as of the Effective Date (both
   before and after giving effect to the Transaction and the Credit
   Events occurring on either such date) and as of the date of each
   subsequent Credit Event which representations, warranties and
   agreements shall survive the execution and delivery of this
   Agreement and the Notes and any subsequent Credit Event (it being
   understood and agreed that any representation or warranty which by
   its terms is made as of a specified date shall be required to be true
   and correct in all material respects only as of such specified date):
   
     7.01  Corporate Status.  The Borrower (i) is a duly
   organized and validly existing corporation in good standing under
   the laws of the jurisdiction of its organization, (ii) has the power
   and authority to own its property and assets and to transact the
   business in which it is engaged and presently proposes to engage
   and (iii) is duly qualified and is authorized to do business and is in
   good standing in each jurisdiction where the ownership, leasing or
   operation of property or the conduct of its business requires such
   qualifications except for failures to be so qualified which, in the
   aggregate, could not reasonably be expected to have a Material
   Adverse Effect.
   
     7.02  Corporate Power and Authority.  The Borrower has
   the corporate power to execute, deliver and perform the terms and
   provisions of each of the Documents to which it is party and has
   taken all necessary corporate action to authorize the execution,
   delivery and performance by it of each of such Documents.  The
   Borrower has duly executed and delivered each of the Documents
   to which it is party, and each of such Documents constitutes its
   legal, valid and binding obligation enforceable in accordance with
   its terms, except to the extent that the enforceability thereof may be
   limited by applicable bankruptcy, insolvency, reorganization, or
   other similar laws generally affecting creditors' rights and by
   equitable principles (regardless of whether enforcement is sought in
   equity or at law).
   
     7.03  No Violation.  Neither the execution, delivery or
   performance by the Borrower of the Documents to which it is a
   party, nor compliance by it with the terms and provisions thereof,
   (i) will contravene any provision of any applicable law, statute, rule
   or regulation or any order, writ, injunction or decree of any court
   or governmental instrumentality, (ii) will conflict with or result in
   any breach of any of the terms, covenants, conditions or provisions
   of, or constitute a default under, or result in the creation or
   imposition of (or the obligation to create or impose) any Lien (except
   pursuant to the Security Documents) upon any of the property or
   assets of the Borrower pursuant to the terms of any indenture,
   mortgage, deed of trust, or any other agreement, contract or
   instrument to which the Borrower is a party or by which it or any
   of its property or assets is bound or to which it may be subject or
   (iii) will violate any provision of the Certificate of Incorporation or
   By-Laws (or similar organizational documents) of the Borrower.
   
     7.04  Governmental Approvals.  No order, consent,
   approval, license, authorization or validation of, or filing, recording
   or registration with (except as have been obtained or made on or
   prior to the Effective Date and are in full force and effect and
   except for any filings of financing statements and other documents
   required by or in connection with the Security Documents and any
   filings, registrations or approvals required under state blue sky
   securities laws in connection with the sale of the Senior Notes), or
   exemption by, any governmental or public body or authority, or any
   subdivision thereof, is required to authorize, or is required in
   connection with, (i) the execution, delivery and performance of any
   Document or (ii) the legality, validity, binding effect or
   enforceability of any such Document.
   
     7.05  Financial Statements; Financial Condition;
   Undisclosed Liabilities; Projections; etc.  (a) (i)  The consolidated
   balance sheets of the Borrower at December 31, 1993, 1994 and
   1995 and the related statements of income and retained earnings and
   changes in financial position of the Borrower for the fiscal years
   ended as of said dates, which have been examined by Arthur
   Andersen, LLP, independent certified public accountants, who delivered
   unqualified opinions in respect thereto and (ii) the pro forma
   (after giving effect to the Transaction) consolidated balance sheet of
   the Borrower as at December 31, 1995 copies of all of which
   financial statements referred to in the preceding clauses (i) and (ii)
   have heretofore been furnished to each Bank, present fairly the
   financial position of the Borrower at the dates of said statements and
   the results of operations for the period covered thereby (or, in the
   case of the pro forma balance sheets, present a good faith estimate
   of the pro forma financial condition of the Borrower (after giving
   effect to the Transaction) at the date thereof).  All such financial
   statements have been prepared in accordance with generally
   accepted accounting principles and practices consistently applied
   except to the extent provided in the notes to said financial statements. 
   Since December 31, 1995, there has been no material adverse
   change in the performance, business, assets, nature of assets,
   contracts, liabilities, operations, properties, condition (financial or
   otherwise) or prospects of the Borrower.
   
     (b)  On and as of the Effective Date, on a pro forma basis
   after giving effect to the Transaction:  (a) the sum of the assets, at
   a fair valuation, of the Borrower will exceed its debts; (b) the
   Borrower has not incurred, does not intend to incur, nor believes
   that it will incur, debts beyond its ability to pay such debts as such
   debts mature; and (c) the Borrower will have sufficient capital with
   which to conduct its business.  For purposes of this Section 7.05(b)
   "debt" means any liability on a claim, and "claim" means (i) right
   to payment, whether or not such a right is reduced to judgment,
   liquidated, unliquidated, fixed, contingent, matured, unmatured,
   disputed, undisputed, legal, equitable, secured, or unsecured or (ii)
   right to an equitable remedy for breach of performance if such
   breach gives rise to a payment, whether or not such right to an
   equitable remedy is reduced to judgment, fixed, contingent,
   matured, unmatured, disputed, undisputed, secured or unsecured.
   
     (c)  Except as fully reflected in the financial statements and
   the notes related thereto described in Section 7.05(a), there were as
   of the Effective Date (and after giving effect to the Transaction) no
   liabilities or obligations with respect to the Borrower of any nature
   whatsoever (whether absolute, accrued, contingent or otherwise and
   whether or not due) which, either individually or in aggregate,
   could reasonably be expected to be material to the Borrower.  As
   of the Effective Date, the Borrower does not know of any basis for
   the assertion against the Borrower of any liability or obligation of
   any nature whatsoever that is not fully reflected in the financial
   statements and the notes related thereto described in Section 7.05(a)
   which, either individually or in the aggregate, could reasonably be
   expected to be material to the Borrower.  As of the Effective Date
   (and after giving effect to the Transaction) the Borrower will have
   no outstanding Indebtedness other than the Loans, the Senior Notes
   and the Existing Indebtedness.
   
     (d)  On and as of the Effective Date, the Projections have
   been prepared on a basis consistent with the financial statements
   referred to in Section 7.05(a) (other than as specifically described
   in the notes to such Projections), and there are no statements or
   conclusions in any of the Projections which are based upon or
   include information known to the Borrower to be misleading in any
   material respect or which fail to take into account material
   information regarding the matters reported therein.  On the Effective
   Date, the Borrower believes that the Projections are reasonable and
   attainable.
   
     (e)  On the Effective Date, the aggregate principal amount
   of outstanding travel, relocation and other expenses advanced by the
   Borrower to its employees for business related activities of the
   Borrower does not exceed $100,000 (determined without regard to
   any write-downs or write-offs of such loans and advances).  On the
   Effective Date, the aggregate principal amount of outstanding loans
   and other advances (not including amounts covered by the preceding
   sentence) to key operating employees and officers does not exceed
   $700,000 (determined without regard for any write-downs or write-
   offs of such loans or advances).
   
     7.06  Litigation.  (a) There are no actions, suits or
   proceedings pending or, to the best knowledge of the Borrower,
   threatened (i) with respect to any Document or the transactions
   contemplated thereby, (ii) with respect to any Indebtedness of the
   Borrower, or (iii) that could reasonably be expected to have a
   Material Adverse Effect.
   
     (b)  There are no material investigations pending or, to the
   best knowledge of the Borrower, threatened by any governmental
   entity (including, without limitation, the DHHS or any agency of
   the State of California or any other state, but excluding legislative
   and regulatory investigations and proceedings relating to the clinical
   laboratory industry in general which could not reasonably be
   expected to have a Material Adverse Effect) with respect to the
   business practices or procedures of the Borrower (including,
   without limitation, sales and marketing, pricing and billing
   practices).
   
     7.07  True and Complete Disclosure.  All factual
   information (taken as a whole) heretofore or contemporaneously
   furnished by the Borrower in writing to any Bank (including,
   without limitation, all information contained in the Documents and
   in the prospectus for the Senior Notes) for purposes of or in
   connection with this Agreement or the Transaction is, and all other
   such factual information (taken as a whole) hereafter furnished by
   the Borrower in writing to any Bank will be, true and accurate in
   all material respects on the date as of which such information is
   dated or certified and not incomplete by omitting to state any fact
   necessary to make such information (taken as a whole) not
   misleading in any material respect at such time in light of the
   circumstances under which such information was provided.
   
     7.08  Use of Proceeds; Margin Regulations.  (a)  All
   proceeds of Revolving Loans and Swingline Loans incurred after
   the Effective Date shall be used for the Borrower's working capital
   purposes.
   
     (b)  No part of the proceeds of any Loan will be used to
   purchase or carry any Margin Stock or to extend credit for the
   purpose of purchasing or carrying any Margin Stock.  Neither the
   making of any Loan nor the use of the proceeds thereof nor the
   occurrence of any other Credit Event will violate or be inconsistent
   with the provisions of Regulation G, T, U or X of the Board of
   Governors of the Federal Reserve System.
   
     7.09  Tax Returns and Payments.  All Federal, state and
   other material returns, statements, forms and reports for taxes (the
   "Returns") required to be filed by or with respect to the income,
   properties or operations of the Borrower have been timely filed with
   the appropriate taxing authority.  The Returns accurately reflect all
   liability for material taxes of the Borrower for the periods covered
   thereby.  The Borrower has paid all material taxes payable by it
   other than taxes which are not yet due and payable, and other than
   those contested in good faith by appropriate proceedings and for
   which adequate reserves have been established in accordance with
   GAAP.  The Borrower has been verbally notified by the Tax and
   Permit Division of the City of Los Angeles of a possible claim for
   unpaid taxes based on the Borrower's gross receipts from 1991 to
   1993 (inclusive) and the Borrower has submitted a claim for full
   indemnification against any loss or expense arising therefrom
   pursuant to the Agreement and Plan of Merger and Reorganization
   between Corning Incorporated, various related entities and MetCal,
   Inc., dated as of January 19, 1993.  There is no material action,
   suit, proceeding, investigation, audit, or claim now pending or, to
   the best knowledge of the Borrower, threatened (including as
   described in the previous sentence) by any authority regarding any
   taxes relating to the Borrower.  As of the Effective Date, the
   Borrower has not entered into an agreement or waiver or been
   requested to enter into an agreement or waiver extending any statute
   of limitations relating to the payment or collection of taxes of the
   Borrower, or is aware of any circumstances that would cause the
   taxable years or other taxable periods of the Borrower not to be
   subject to the normally applicable statute of limitations.  The
   Borrower has not provided, with respect to itself or property held
   by it, any consent under Section 341 of the Code.  The Borrower
   has not incurred, and will not incur, any material tax liability in
   connection with the Transaction and the other transactions
   contemplated hereby.
   
     7.10  Security Agreement.  (a)  The provisions of the
   Security Agreement are effective to create in favor of the Collateral
   Agent for the benefit of the Secured Creditors a legal, valid and
   enforceable security interest in all right, title and interest of the
   Borrower in the Security Agreement Collateral and the Collateral
   Agent, for the benefit of the Secured Creditors, has a fully perfected
   first lien on, and security interest in, all right, title and
   interest of the Borrower, in all of the Security Agreement Collateral,
   subject to no other Liens other than Permitted Liens.  The Borrower
   has good and marketable title to all Security Agreement Collateral,
   free and clear of all Liens except Permitted Liens.
   
     (b)  Schedule III contains a true and complete list of each
   Real Property owned or leased by the Borrower on the Effective
   Date, and the type of interest therein held by the Borrower.  On the
   Effective Date, the Borrower does not own any interest in any Real
   Property other than Leaseholds.
   
     7.11  Capitalization.  On the Effective Date, Schedule IV
   contains a true and complete description of the capitalization of the
   Borrower.  All of such outstanding shares have been duly and
   validly issued, are fully paid and nonassessable and are free of
   preemptive rights.  As of the Effective Date, except as provided on
   Schedule IV, the Borrower does not have outstanding any securities
   convertible into or exchangeable for its capital stock or outstanding
   any rights to subscribe for or to purchase, or any options for the
   purchase of, or any agreements providing for the issuance
   (contingent or otherwise) of, or any calls, commitments or claims
   of any character relating to, its capital stock.  Under the terms of
   the Borrower Preferred Stock, Dividends are payable in respect of
   the Borrower Preferred Stock in an aggregate amount not in excess
   of $36,000 per fiscal quarterly period of the Borrower.
   
     7.12  Subsidiaries.  On the Effective Date, the Borrower has
   no Subsidiaries.
   
     7.13 Senior Notes.  As of the Effective Date, the Senior
   Notes have been duly authorized, issued and delivered in
   accordance with applicable law and the prospectus relating thereto,
   and such prospectus, as of the date of its issue, does not contain any
   untrue statement of a material fact nor omit to state a material fact
   necessary in order to make the statements contained therein, in the
   light of the circumstances under which they were made, not
   misleading.
   
     7.14  Indebtedness.  Schedule VI sets forth a true and
   complete list of any Indebtedness (other than the Loans, the Letters
   of Credit and the Senior Notes) of the Borrower to be outstanding
   as of the Effective Date after giving effect to the Transaction (the
   "Existing Indebtedness"), in each case showing the aggregate
   amount thereof and the name of the respective obligor and any other
   entity which directly or indirectly guaranteed such debt.
   
     7.15  Compliance with Statutes, etc.  (a) The Borrower is in
   material compliance with all applicable material statutes, regulations
   and orders of, and all applicable restrictions imposed by, all
   governmental bodies, domestic or foreign, in respect of (a) the
   conduct of its business, including, without limitation, (i) the Social

   Borrower and except as set forth in the prospectus relating to the
   Senior Notes, there are no current proposals for adoption of new

   governmental body, domestic or foreign, affecting the clinical
   laboratory industry specifically and applicable to the Borrower,
   which proposals, in either case, if adopted (in their current form or
   otherwise), could have a Material Adverse Effect.
   
     7.16  Compliance with ERISA.  Each Plan is in substantial
   compliance with ERISA and the Code; no Reportable Event has
   occurred with respect to a Plan which has or could reasonably be
   expected to result in material liability; no Plan is insolvent or in

   issued under such Environmental Laws.  There are no past, pending
   or, to the best knowledge of the Borrower, threatened material
   Environmental Claims against the Borrower or any Real Property
   owned or operated by the Borrower.  There are no facts,
   circumstances, conditions or occurrences on any Real Property
   owned or operated by the Borrower or, to the best knowledge of the
   Borrower, on any property adjoining or in the vicinity of any such
   Real Property that could reasonably be expected (i) to form the
   basis of a material Environmental Claim against the Borrower or
   any Real Property owned or operated by the Borrower or (ii) to
   cause any such Real Property to be subject to any material
   restrictions on the ownership, occupancy, use or transferability of such
   Real Property under any applicable Environmental Law.
   
     (b)  Except in small amounts necessary in the ordinary
   course of business of the Borrower and in compliance in all material

   indenture, security agreement and other debt instrument by which
   it is bound, except such instances of non-performance as could not,
   individually or in the aggregate, reasonably be expected to have a
   Material Adverse Effect.
   
     8.10  Payment of Taxes.  The Borrower will pay and
   discharge all taxes, assessments and governmental charges or levies
   imposed upon it or upon its income or profits, or upon any
   properties belonging to it, prior to the date on which penalties
   would otherwise attach thereto, and all lawful claims which, if
   unpaid, might become a lien or charge upon any properties of the
   Borrower; provided, that the Borrower shall not be required to pay
   any such tax, assessment, charge, levy or claim which is being
   contested in good faith and by proper proceedings if it has
   maintained adequate reserves with respect thereto in accordance
   with generally accepted accounting principles.
   
     8.11  Use of Proceeds.  All proceeds of the Loans shall be
   used as provided in Section 7.08.
   
     8.12  UCC Searches.  On or prior to the 60th day following
   the Effective Date, the Borrower shall deliver to the Agent (at the
   Borrower's own cost) copies of Request for Information or Copies
   (UCC-11), or equivalent reports verifying that all financing
   statements necessary or, in the opinion of the Collateral Agent
   desirable, to perfect (or maintain the perfection of) the security
   interests purported to be created (or maintained) by the Security
   Agreement shall have been properly recorded and filed.
   
     8.13  Intellectual Property Rights.  The Borrower will
   maintain in full force and effect all Intellectual Property rights
   necessary or appropriate to the business of the Borrower and take
   no action (including, without limitation, the licensing of Intellectual
   Property), or fail to take an action, as the case may be, in
   connection with such Intellectual Property rights which could
   reasonably be expected to result in a Material Adverse Effect.  The
   Borrower will diligently prosecute all pending applications filed in
   connection with seeking or seeking to perfect the Intellectual
   Property rights and take all other reasonable actions necessary for
   the protection and maintenance of the Intellectual Property rights
   necessary or appropriate to the business of the Borrower at all times
   from and after the Effective Date except where the failure to do any
   of the foregoing is not reasonably likely to have a Material Adverse
   Effect.
   
     8.14  Registry.  The Borrower hereby designates the Agent
   to serve as the Borrower's agent, solely for purposes of this Section
   8.14, to maintain a register (the "Register") on which it will record
   the Revolving Loan Commitments from time to time of each of the
   Banks, the Loans made by each of the Banks and each repayment
   in respect of the principal amount of the Loans of each Bank. 
   Failure to make any such recordation, or any error in such
   recordation shall not affect the Borrower's obligations in respect of
   such Loans.  With respect to any Bank, the transfer of the
   Revolving Loan Commitment of such Bank and the rights to the
   principal of, and interest on, any Loan made pursuant to such
   Revolving Loan Commitment shall not be effective until such
   transfer is recorded on the Register maintained by the Agent with
   respect to ownership of such Revolving Loan Commitment and
   Loans and prior to such recordation all amounts owing to the
   transferor with respect to such Revolving Loan Commitment and
   Loans shall remain owing to the transferor.  The registration of
   assignment or transfer of all or part of any Revolving Loan
   Commitment and Loans shall be recorded by the Agent on the
   Register only upon the acceptance by the Agent of a properly
   executed and delivered Assignment and Assumption Agreement
   pursuant to Section 13.04(b).  Coincident with the delivery of such
   an Assignment and Assumption Agreement to the Agent for
   acceptance and registration of assignment or transfer of all or part
   of a Loan, or as soon thereafter as practicable, the assigning or
   transferor Bank shall surrender the Note evidencing such Loan, and
   thereupon one or more new Notes in the same aggregate principal
   amount shall be issued to the assigning or transferor Bank and/or
   the new Bank.  The Borrower agrees to indemnify the Agent from
   and against any and all losses, claims, damages and liabilities of
   whatsoever nature which may be imposed on, asserted against or
   incurred by the Agent in performing its duties under this Section
   8.14.
   
     8.15  Further Actions.  The Borrower shall at its own
   expense, make, execute, endorse, acknowledge, file and/or deliver
   to the Collateral Agent from time to time such conveyances,
   financing statements, transfer endorsements, powers of attorney,
   certificates, reports and other assurances or instruments or executed
   counterparts to the Security Agreement and take such further steps
   relating to perfecting (or maintaining the perfection of) the security
   interest of the Secured Creditors in the Security Agreement
   Collateral as the Collateral Agent may reasonably require and in
   each case within 60 days from the date such action is requested to
   be taken.  Furthermore, not later than 60 days from the date of any
   such request by the Agent or the Required Banks the Borrower shall
   cause to be delivered to the Collateral Agent such opinions of
   counsel and other documents as may be reasonably requested by the
   Agent or the Required Banks to assure themselves that this Section
   8.15 has been complied with.
   
     8.16  Permitted Acquisitions.  (a) Subject to the remaining
   provisions of this Section 8.16 applicable thereto and the
   requirements contained in the definition of Permitted Acquisition,
   the Borrower may from time to time, on or after the Effective Date,
   effect Permitted Acquisitions so long as:
   
        (i)  with respect to each Permitted Acquisition, (x)
        no Default or Event of Default is in existence at the time of
        the consummation of such Permitted Acquisition or would
        exist after giving effect thereto (in determining compliance
        with financial covenants hereunder after giving effect to the
        proposed Permitted Acquisition, the Borrower's historical
        results for the relevant period set forth in such financial
        covenants shall be adjusted for all Indebtedness incurred in
        connection with the proposed Permitted Acquisition but
        shall not otherwise be adjusted for the effects of such
        proposed Permitted Acquisition), (y) such Permitted
        Acquisition shall comply with the terms of the Senior Notes
        Indenture and the Borrower shall furnish the Agent and the
        Banks with an officer's certificate executed by the President
        or the Chief Financial Officer certifying as to compliance
        with this clause (y) and (z) in the case of any Permitted
        Acquisition for which the aggregate purchase price payable
        by the Borrower is $500,000 or more, the Borrower shall
        furnish the Agent and the Banks with an officer's certificate
        executed by the President or the Chief Financial Officer
        certifying as to compliance with clause (x) above;
   
       (ii)  with respect to all Permitted Acquisitions on and
        after the Effective Date, during each Permitted Acquisition
        Period, the total purchase price of all such Permitted
        Acquisitions shall not exceed in the aggregate (x)
        $5,000,000 in cash paid, or to be paid, by the Borrower in
        connection with such Permitted Acquisitions and (y)
        $5,000,000 in fair market value of all common stock of the
        Borrower issued, or to be issued, in connection with such
        Permitted Acquisition (such fair market value to be
        determined by taking the average closing price of such stock
        on the Nasdaq Stock Market/Nasdaq National Market or on
        another national securities exchange for the 10 trading days
        immediately preceding the date of the applicable Permitted
        Acquisition or if the common stock is not trading on such
        market or exchange such other fair market value as shall be
        acceptable to the Agent (the "Fair Market Value")); and
   
      (iii)  in the case of any Permitted Acquisition for
        which the aggregate purchase price payable by the Borrower
        is $500,000 or more, the amount of the Consolidated
        EBITDA of the assets being acquired in connection with the
        Permitted Acquisition for the period of four consecutive
        fiscal quarters (taken as one accounting period) last ended
        prior to the date of such Permitted Acquisition shall be
        greater than zero, provided that in determining such
        EBITDA the Borrower may take into account such cost
        savings as shall reasonably be expected to be obtained in
        connection with the acquisition, and provided further that,
        the amount of Consolidated EBITDA and the cost savings,
        if any, resulting from such acquisition shall each be
        reasonably verifiable to the satisfaction of the Agent.
   
     (b)  The Borrower shall, on the date of a Permitted Acquisition,
   grant to the Collateral Agent, for the benefit of the Secured
   Creditors, a first priority perfected security interest in all inventory
   and receivables of the Borrower acquired in connection with the
   Permitted Acquisition and, within three Business Days of the date
   of such Permitted Acquisition, shall take all actions requested by the
   Agent or the Required Banks (including, without limitation, the
   obtaining of UCC-11's and the filing of UCC-1's) in connection
   with the granting of such security interests.  All security interests
   required to be granted pursuant to this Section 8.16 shall be granted
   pursuant to the Security Agreement, including by way of an
   amendment (satisfactory in form and substance to the Agent) to the
   Security Agreement, if necessary, and shall (except as otherwise
   consented to by the Agent and the Required Banks) constitute valid
   and enforceable perfected security interests prior to the rights of all
   third Persons and subject to no other Liens except such Liens as are
   permitted by Section 9.01.  Any required financing statements shall
   be duly recorded or filed in such manner and in such places as are
   required by law to establish, perfect, preserve and protect the
   Liens, in favor of the Collateral Agent for the benefit of the Secured
   Creditors, granted pursuant to the Security Agreement and all taxes,
   fees and other charges payable in connection therewith shall be paid
   in full by the Borrower.  At the time of the execution and delivery
   of any amendment to the Security Agreement or of any financing
   statements in connection with a Permitted Acquisition, the Borrower
   shall cause to be delivered to the Collateral Agent such opinions of
   counsel and other related documents as may be reasonably requested
   by the Collateral Agent or the Required Banks to assure themselves
   that this Section has been complied with.  Except as specifically set
   forth above, all actions required by this Section 8.16(b) shall be
   completed no later than the date on which the Permitted Acquisition
   is effected.
   
     (c)  The consummation of each Permitted Acquisition shall
   be deemed to be a representation and warranty by the Borrower that
   all conditions thereto have been satisfied and that same is permitted
   in accordance with the terms of this Agreement, which
   representation and warranty shall be deemed to be a representation
   and warranty for all purposes hereunder, including, without
   limitation, Sections 6 and 10.
   
   
     Section 9.  Negative Covenants.  The Borrower covenants
   and agrees that on and after the Effective Date and until the Total
   Revolving Loan Commitment and all Letters of Credit have terminated
   and the Loans, Notes and Unpaid Drawings, together with
   interest, Fees and all other Obligations, are paid in full:
   
     9.01  Liens.  (a) The Borrower will not create, incur,

   such property or assets subject to an understanding or agreement,
   contingent or otherwise, to repurchase such property or assets
   (including sales of accounts receivable with recourse to the
   Borrower), or assign any right to receive income or permit the
   filing of any financing statement under the UCC or any other
   similar notice of Lien under any similar recording or notice statute;
   provided, that the provisions of this Section 9.01 shall not prevent
   the creation, incurrence, assumption or existence of the following
   (liens described below are herein referred to as "Permitted Liens"):
   
        (i)  Liens with respect to taxes, assessments, levies
        or other governmental charges not yet due or which are

        accordance with generally accepted accounting principles;
   
       (ii)  Liens in respect of property or assets of the

        materialmen's, mechanics' and landlords' and other similar
        Liens arising in the ordinary course of business, and
        (x) which do not in the aggregate materially detract from the
        value of such property or assets or materially impair the use
        thereof in the operation of the business of the Borrower or
        (y) which are being contested in good faith by appropriate
        proceedings, which proceedings have the effect of preventing

        payment of Indebtedness arising under such Capitalized
        Lease Obligation and the Lien encumbering the asset giving
        rise to the Capitalized Lease Obligation and the proceeds
        thereof do not encumber any other asset of the Borrower;
   
      (vii)  Liens (other than any Lien imposed by ERISA)
        on property of the Borrower incurred or deposits made in
        the ordinary course of business (x) in connection with

        (exclusive of obligations for the payment of borrowed
        money), provided that the aggregate amount of cash and the
        fair market value of the property encumbered by Liens
        described in this clause (vii)(y) shall not exceed $250,000;
   
     (viii)  Liens placed upon equipment or machinery used
        in the ordinary course of the business of the Borrower at the
        time of purchase thereof by the Borrower to secure
        Indebtedness incurred to pay all or a portion of the purchase
        price thereof, provided that (x) the aggregate principal
        amount of all Indebtedness secured by Liens permitted by
        this clause (viii) does not exceed at any one time outstanding
        $250,000 with respect to all machinery and equipment and
        (y) in all events, the Lien encumbering the equipment or
        machinery so acquired does not encumber any other asset of
        the Borrower;
   
       (ix)  Liens created by leases or subleases granted to
        others not interfering in any material respect with the
        business of the Borrower;

   sole satisfaction.
    
     12.03  Lack of Reliance on the Agent.  Independently and
   without reliance upon the Agent, each Bank and the holder of each
   Note, to the extent it deems appropriate, has made and shall
   continue to make (i) its own independent investigation of the
   financial condition and affairs of the Borrower in connection with
   the making and the continuance of the Loans and the participation
   in Letters of Credit and the taking or not taking of any action in
   connection herewith and (ii) its own appraisal of the credit-
   
   worthiness of the Borrower and, except as expressly provided in
   this Agreement, the Agent shall not have any duty or responsibility,
   either initially or on a continuing basis, to provide any Bank or the
   holder of any Note with any credit or other information with respect
   thereto, whether coming into its possession before the making of the
   Loans, the participation in the Letters of Credit or at any time or
   times thereafter.  The Agent shall not be responsible to any Bank or
   the holder of any Note for any recitals, statements, information,
   representations or warranties herein or in any document, certificate
   or other writing delivered in connection herewith or for the execution, 
   effectiveness, genuineness, validity, enforceability, perfection,
   priority or sufficiency of this Agreement or any other Credit
   Document or the financial condition of the Borrower or be required
   to make any inquiry concerning either the performance or observance
   of any of the terms, provisions or conditions of this
   Agreement or any other Credit Document, or the financial condition
   of the Borrower or the existence or possible existence of any
   Default or Event of Default.
   
     12.04  Certain Rights of the Agent.  If the Agent shall
   request instructions from the Required Banks with respect to any act
   or action (including failure to act) in connection with this
   Agreement or any other Credit Document, the Agent shall be
   entitled to refrain from such act or taking such action unless and
   until the Agent shall have received written instructions from the
   Required Banks; and the Agent shall not incur liability to any
   Person by reason of so refraining.  Without limiting the foregoing,
   no Bank and no holder of any Note shall have any right of action
   whatsoever against the Agent as a result of the Agent acting or
   refraining from acting hereunder or under any other Credit Document
   in accordance with the instructions of the Required Banks.
   
     12.05  Reliance.  The Agent shall be entitled to rely, and
   shall be fully protected in relying, upon any note, writing,
   resolution, notice, statement, certificate, telex, teletype or facsimile
   message, cablegram, radiogram, legal opinion, order or other
   document or telephone message signed, sent or made by any Person
   that the Agent believed to be the proper Person, and, with respect
   to all legal matters pertaining to this Agreement and any other
   Credit Document and its duties hereunder and thereunder, upon
   advice of counsel selected by it.
   
     12.06  Indemnification.  To the extent the Agent is not
   reimbursed and indemnified by the Borrower, the Banks will
   reimburse and indemnify the Agent, in proportion to their
   respective "percentages" as used in determining the Required
   Banks, for and against any and all liabilities, obligations, losses,
   damages, penalties, claims, actions, judgments, suits, costs,
   expenses or disbursements of whatsoever kind or nature which may
   be imposed on, asserted against or incurred by the Agent in
   performing its duties hereunder or under any other Credit
   Document, in any way relating to or arising out of this Agreement
   or any other Credit Document; provided that no Bank shall be liable
   for any portion of such liabilities, obligations, losses, damages,
   penalties, claims, actions, judgments, suits, costs, expenses or
   disbursements resulting from the Agent's gross negligence or willful
   misconduct.
   
     12.07  The Agent in Its Individual Capacity.  With respect
   to its obligation to make Loans under this Agreement, the Agent
   shall have the rights and powers specified herein for a "Bank" and
   may exercise the same rights and powers as though it were not
   performing the duties specified herein; and the term "Banks,"
   "Required Banks," "holders of Notes" or any similar terms shall,
   unless the context clearly otherwise indicates, include the Agent in
   its individual capacity.  The Agent may accept deposits from, lend
   money to, and generally engage in any kind of banking, trust or
   other business with the Borrower or any Affiliate of the Borrower
   as if it were not performing the duties specified herein, and may
   accept fees and other consideration from the Borrower for services
   in connection with this Agreement and otherwise without having to
   account for the same to the Banks.
   
     12.08  Holders.  The Agent may deem and treat the payee
   of any Note as the owner thereof for all purposes hereof unless and
   until a written notice of the assignment, transfer or endorsement
   thereof, as the case may be, shall have been filed with the Agent,
   as the case may be.  Any request, authority or consent of any
   Person who, at the time of making such request or giving such
   authority or consent, is the holder of any Note shall be conclusive
   and binding on any subsequent holder, transferee, assignee or
   indorsee, as the case may be, of such Note or of any Note or Notes
   issued in exchange therefor.
   
     12.09  Resignation by the Agent.  (a)  The Agent may resign
   from the performance of all its functions and duties hereunder
   and/or under the other Credit Documents at any time by giving 15
   Business Days' prior written notice to the Borrower and the Banks. 
   Such resignation shall take effect upon the appointment of a successor
   Agent pursuant to clauses (b) and (c) below or as otherwise
   provided below.
   
     (b)  Upon any such notice of resignation, the Required
   Banks shall appoint a successor Agent hereunder or thereunder who
   shall be a commercial bank or trust company reasonably acceptable
   to the Borrower (it being understood and agreed that any Bank is
   deemed to be acceptable to the Borrower).
   
     (c)  If a successor Agent shall not have been so appointed
   within such 15 Business Day period, the Agent, with the consent of
   the Borrower, shall then appoint a successor Agent who shall serve
   as Agent hereunder or thereunder until such time, if any, as the
   Banks appoint a successor Agent as provided above.
   
     (d)  If no successor Agent has been appointed pursuant to
   clause (b) or (c) above by the 20th Business Day after the date such
   notice of resignation was given by the Agent, the Agent's
   resignation shall become effective and the Banks shall thereafter
   perform all the duties of the Agent hereunder and/or under any
   other Credit Document until such time, if any, as the Banks appoint
   a successor Agent as provided above.
   
   
     Section 13.  Miscellaneous.
   
     13.01  Payment of Expenses, etc.  The Borrower agrees to: 
   (i) whether or not the transactions herein contemplated are
   consummated, pay all reasonable out-of-pocket costs and expenses of the
   Agent and the Collateral Agent (including, without limitation, the
   reasonable fees and disbursements of White & Case) in connection
   with the preparation, execution and delivery of this Agreement and
   the other Credit Documents and the documents and instruments
   referred to herein and therein and any amendment, waiver or
   consent relating hereto or thereto, of the Agent in connection with
   its syndication efforts with respect to this Agreement (including,
   without limitation, the reasonable fees and disbursements of counsel
   for the Agent) and of the Agent, the Collateral Agent and each of
   the Banks in connection with the enforcement of this Agreement and
   the other Credit Documents and the documents and instruments
   referred to herein and therein (including, without limitation, the
   reasonable fees and disbursements of counsel for the Agent, the
   Collateral Agent and for each of the Banks); (ii) pay and hold each
   of the Banks harmless from and against any and all present and
   future stamp, excise and other similar taxes with respect to the
   foregoing matters and save each of the Banks harmless from and
   against any and all liabilities with respect to or resulting from any
   delay or omission (other than to the extent attributable to such
   Bank) to pay such taxes; and (iii) defend, protect, indemnify and
   hold harmless the Agent, the Collateral Agent and each Bank, and
   each of their respective officers, directors, employees,
   representatives and agents (collectively called the "Indemnitees")
   from and against any and all liabilities, obligations (including
   removal or remedial actions), losses, damages (including
   foreseeable and unforeseeable consequential damages and punitive
   damages), penalties, claims, actions, judgments, suits, costs,
   expenses and disbursements (including reasonable attorneys' and
   consultants fees and disbursements) of any kind or nature whatsoever
   that may at any time be incurred by, imposed on or assessed
   against the Indemnitees directly or indirectly based on, or arising or
   resulting from, (a) any investigation, litigation or other proceeding
   (whether or not the Agent, the Collateral Agent or any Bank is a
   party thereto) related to the entering into and/or performance of this
   Agreement or any other Credit Document or the use of any Letter
   of Credit or the proceeds of any Loans hereunder or the
   consummation of any transactions contemplated herein (including,
   without limitation, the issuance of the Senior Notes) or in any other
   Credit Document, (b) the actual or alleged generation, presence or
   Release of Hazardous Materials on or from, or the transportation of
   Hazardous Materials to or from, any Real Property owned or
   operated at any time by the Borrower or; (c) any Environmental
   Claim relating to the Borrower or any Real Property owned or at
   any time operated by the Borrower or; (d) the exercise of the rights
   of the Agent, the Collateral Agent and of any Bank under any of the
   provisions of this Agreement, any Security Document or any other
   Document or any Letter of Credit or any Loans hereunder; or,
   (e) the consummation of any transaction contemplated herein
   (including, without limitation, the issuance of the Senior Notes) or
   in any other Credit Document (the "Indemnified Matters"); regardless
   of when such Indemnified Matter arises, but excluding any such
   liability, obligation, loss, damage, penalty, claim, action, judgment,
   suit, cost, expense or disbursement relating to any Indemnified
   Matter resulting from the gross negligence or willful misconduct of
   any Indemnitee.
   
     13.02  Right of Setoff.  In addition to any rights now or
   hereafter granted under applicable law or otherwise, and not by way
   of limitation of any such rights, upon the occurrence and during the
   continuance of an Event of Default, each Bank is hereby authorized
   at any time or from time to time, without presentment, demand,
   protest or other notice of any kind to the Borrower or to any other
   Person, any such notice being hereby expressly waived, to set off
   and to appropriate and apply any and all deposits (general or
   special) and any other Indebtedness at any time held or owing by such
   Bank (including, without limitation, by branches and agencies of
   such Bank wherever located) to or for the credit or the account of
   the Borrower against and on account of the Obligations and
   liabilities of the Borrower to such Bank under this Agreement or
   under any of the other Credit Documents, including, without
   limitation, all interests in Obligations purchased by such Bank
   pursuant to Section 13.06(b), and all other claims of any nature or
   description arising out of or connected with this Agreement or any
   other Document, irrespective of whether or not such Bank shall
   have made any demand hereunder and although said Obligations,
   liabilities or claims, or any of them, shall be contingent or
   unmatured.
   
     13.03  Notices.  Except as otherwise expressly provided
   herein, all notices and other communications provided for
   hereunder shall be in writing (including telegraphic, telex, facsimile
   or cable communication) and mailed, telegraphed, telexed,
   facsimilied, cabled or delivered:  if to the Borrower, at its address
   specified opposite its signature below; if to any Bank, at its address
   specified on Schedule I; and if to the Agent, at its Notice Office; or,
   as to the Agent, at such other address as shall be designated by the
   Agent in a written notice to the other parties hereto and, as to each
   Bank, at such other address as shall be designated by such Bank in
   a written notice to the Borrower and the Agent.  All such notices
   and communications shall, when mailed, telegraphed, telexed,
   facsimilied, or cabled or sent by overnight courier, be effective
   when deposited in the mails, delivered to the telegraph company,
   cable company or overnight courier, as the case may be, or sent by
   telex or facsimile device, except that notices and communications
   to the Agent and the Borrower shall not be effective until received
   by the Agent and the Borrower, as the case may be.
   
     13.04  Benefit of Agreement; Assignments; Participations. 
   (a)  This Agreement shall be binding upon and inure to the benefit
   of and be enforceable by the respective successors and assigns of
   the parties hereto; provided, however, the Borrower may not assign
   or transfer any of its rights, obligations or interest hereunder or
   under any other Credit Document without the prior written consent
   of the Banks; and provided further, that although any Bank may
   transfer, assign or grant participations in its rights hereunder, such
   Bank shall remain a "Bank" for all purposes hereunder (and may
   not transfer or assign all or any portion of its Commitments
   hereunder except as provided in Section 13.04(b)) and the
   transferee, assignee or participant, as the case may be, shall not
   constitute a "Bank" hereunder; and provided further, that no Bank
   shall transfer or grant any participation under which the participant
   shall have rights to approve any amendment to or waiver of this
   Agreement or any other Credit Document except to the extent such
   amendment or waiver would:  (i) extend the final scheduled
   maturity of any Loan, Note or Letter of Credit (unless such Letter
   of Credit is not extended beyond the Revolving Loan Maturity
   Date) in which such participant is participating, or reduce the rate
   or extend the time of payment of interest or Fees thereon (except in
   connection with a waiver of applicability of any post-default
   increase in interest rates) or reduce the principal amount thereof, or
   increase the Revolving Loan Commitment in which such participant
   is participating over the amount thereof then in effect (it being
   understood that a waiver of any Default or Event of Default or of
   a mandatory reduction in the Total Revolving Loan Commitment or
   of a mandatory prepayment shall not constitute a change in the
   terms of such participation, and that an increase in any Revolving
   Loan Commitment shall be permitted without the consent of any
   participant if the participant's participation is not increased as a
   result thereof); (ii) consent to the assignment or transfer by the
   Borrower of any of its rights and obligations under this Agreement;
   or (iii) release all or substantially all of the Collateral under the
   Security Documents (except as expressly provided in the Credit
   Documents) supporting the Loans hereunder in which such participant
   is participating.  In the case of any such participation, the
   participant shall not have any rights under this Agreement or any of
   the other Credit Documents (the participant's rights against such
   Bank in respect of such participation to be those set forth in the
   agreement executed by such Bank in favor of the participant relating
   thereto) and all amounts payable by the Borrower hereunder shall
   be determined as if such Bank had not sold such participation.
   
     (b)  Notwithstanding the foregoing, any Bank (or any Bank
   together with one or more other Banks) may (x) (A) pledge its
   Loans and/or Notes hereunder to a Federal Reserve Bank in support
   of borrowings made by such Bank from such Federal Reserve Bank
   or (B) assign all or a portion of its Revolving Loan Commitment
   and related outstanding Obligations hereunder to its parent
   company, principal office and/or any Affiliate of such Bank which
   is at least 50% owned by such Bank or its parent company or to one
   or more other Banks or (y) assign all, or if less than all, a portion
   equal to at least $5,000,000 in the aggregate for the assigning Bank
   or assigning Banks (provided that the $5,000,000 limitation shall
   not apply to assignments to an assignee who was a Bank
   immediately prior to the assignment), of such Loans or Revolving
   Loan Commitment and related outstanding Obligations hereunder
   to one or more Eligible Transferees each of which assignees shall
   become a party to this Agreement as a Bank by execution of an
   assignment and assumption agreement (the "Assignment and
   Assumption Agreement") substantially in the form of Exhibit J
   (appropriately completed); provided that:  (i) at such time Schedule
   I shall be deemed modified to reflect the Revolving Loan Commitment
   of such new Bank and of the existing Banks; (ii) new Notes
   will be issued to such new Bank and to the assigning Bank upon the
   request of such new Bank or assigning Bank, such new Notes to be
   in conformity with the requirements of Section 1.05 to the extent
   needed to reflect the revised Revolving Loan Commitments; (iii) the
   consent of Paribas shall be required; (iv) the Agent shall receive at
   the time of each such assignment, from the assigning Bank, the
   payment of a non-refundable assignment fee of $3,000.  To the
   extent of any assignment pursuant to this Section 13.04(b), the
   assigning Bank shall be relieved of its obligations hereunder with
   respect to its assigned Revolving Loan Commitment.
   
     (c)  To the extent that at the time of any assignment pursuant
   to Section 13.04(b) to a Person not already a Bank hereunder, if the
   Person purchasing such assignment (the "Assignee") would be
   entitled to charge the Borrower for the reimbursement of Taxes
   pursuant to Section 4.04 in excess of the aggregate of such amounts
   permitted to be charged by the assigning Bank immediately prior to
   such assignment (which differences may arise, for among other
   reasons, because of differences between the assignee and the
   assigning Bank, or because of the different laws, treaties or
   regulations, or interpretations thereof, applicable to such Persons),
   the Borrower shall not be obligated to pay such excess Taxes, it
   being understood and agreed, however, that the Borrower shall be
   obligated to pay to such assignee all other Taxes which are
   otherwise required to be reimbursed pursuant to said Section 4.04
   (including, without limitation, all such Taxes payable as a result of
   events occurring after the date of the respective assignment).
   
     13.05  No Waiver; Remedies Cumulative.  No failure or
   delay on the part of the Agent, the Collateral Agent or any Bank or
   any holder of any Note in exercising any right, power or privilege
   hereunder or under any other Credit Document and no course of
   dealing between the Borrower and the Agent, the Collateral Agent
   or any Bank or the holder of any Note shall operate as a waiver
   thereof; nor shall any single or partial exercise of any right, power
   or privilege hereunder or under any other Credit Document
   preclude any other or further exercise thereof or the exercise of any
   other right, power or privilege hereunder or thereunder.  The
   rights, powers and remedies herein or in any other Credit Document
   expressly provided are cumulative and not exclusive of any
   rights, powers or remedies which the Agent, the Collateral Agent
   or any Bank or the holder of any Note would otherwise have.  No
   notice to or demand on the Borrower in any case shall entitle the
   Borrower to any other or further notice or demand in similar or
   other circumstances or constitute a waiver of the rights of the
   Agent, the Collateral Agent or any Bank or the holder of any Note
   to any other or further action in any circumstances without notice
   or demand.
   
     13.06  Payments Pro Rata.  (a)  The Agent agrees that
   promptly after its receipt of each payment from or on behalf of the
   Borrower in respect of any Obligations hereunder, it shall distribute
   such payment to the Banks pro rata based upon their respective
   shares, if any, of the Obligations with respect to which such
   payment was received.
   
     (b)  Each of the Banks agrees that, if it should receive any
   amount hereunder (whether by voluntary payment, by realization
   upon security, by the exercise of the right of setoff or banker's lien,
   by counterclaim or cross action, by the enforcement of any right
   under the Credit Documents, or otherwise), which is applicable to
   the payment of the principal of, or interest on, the Loans, Unpaid
   Drawings, Commitment Commission or Fees, of a sum which with
   respect to the related sum or sums received by other Banks is in a
   greater proportion than the total of such Obligation then owed and
   due to such Bank bears to the total of such Obligation then owed
   and due to all of the Banks immediately prior to such receipt, then
   such Bank receiving such excess payment shall purchase for cash
   without recourse or warranty from the other Banks an interest in the
   Obligations of the Borrower to such Banks in such amount as shall
   result in a proportional sharing by all the Banks in such amount;
   provided that if all or any portion of such excess amount is
   thereafter recovered from such Bank, such purchase shall be
   rescinded and the purchase price restored to the extent of such
   recovery, but without interest.
   
     13.07  Calculations; Computations; Accounting Terms. 
   (a)  The financial statements to be furnished to the Banks pursuant
   hereto shall be made and prepared in accordance with generally
   accepted accounting principles in the United States consistently
   applied throughout the periods involved (except as set forth in the
   notes thereto or as otherwise disclosed in writing by the Borrower
   to the Banks); provided that, except as otherwise specifically
   provided herein, all computations determining compliance with Section
   9 shall utilize accounting principles and policies in conformity with
   those used to prepare the historical financial statements delivered to
   the Banks pursuant to Section 7.05(a) (with the foregoing generally
   accepted accounting principles, subject to the preceding provision,
   herein called "GAAP").
   
     (b)  All computations of interest and Fees hereunder shall be
   made on the basis of a year of 360 days for the actual number of
   days (including the first day but excluding the last day) occurring
   in the period for which such interest or Fees are payable.
   
     13.08  GOVERNING LAW; SUBMISSION TO
   JURISDICTION; VENUE.  (A)  THIS AGREEMENT AND
   THE OTHER CREDIT DOCUMENTS AND THE RIGHTS
   AND OBLIGATIONS OF THE PARTIES HEREUNDER AND
   THEREUNDER SHALL BE CONSTRUED IN ACCORDANCE

   FOR AND ON ITS BEHALF, AND IN RESPECT OF ITS
   PROPERTY, SERVICE OF ANY AND ALL LEGAL
   PROCESS, SUMMONS, NOTICES AND DOCUMENTS
   WHICH MAY BE SERVED IN ANY SUCH ACTION OR
   PROCEEDING.  IF FOR ANY REASON SUCH DESIGNEE,
   APPOINTEE AND AGENT SHALL CEASE TO BE AVAIL-

   DESIGNATE A NEW DESIGNEE, APPOINTEE AND AGENT

   OF PROCESS OUT OF ANY OF THE AFOREMENTIONED
   COURTS IN ANY SUCH ACTION OR PROCEEDING BY

     13.09  Counterparts.  This Agreement may be executed in
   any number of counterparts and by the different parties hereto on
   separate counterparts, each of which when so executed and
   delivered shall be an original, but all of which shall together
   constitute one and the same instrument.  A set of counterparts
   executed by all the parties hereto shall be lodged with the Borrower
   and the Agent.
   
     13.10  Effectiveness.  This Agreement shall become
   effective on the date (the "Effective Date") on which (i) the
   Borrower, the Agent and each of the Banks shall have signed a copy
   hereof (whether the same or different copies) and shall have
   delivered the same to the Agent at its Notice Office or, in the case
   of the Banks, shall have given to the Agent telephonic (confirmed
   in writing), written or telex notice (actually received) at such office
   that the same has been signed and mailed to it and (ii) the conditions
   contained in Sections 5 and 6 are met to the satisfaction of the
   Agent and the Required Banks.  Unless the Agent has received
   actual notice from any Bank that the conditions described in the
   preceding sentence have not been met to its satisfaction, then after
   the Effective Date and upon the Agent's good faith determination
   that the conditions described in the preceding sentence have been
   met, the Effective Date shall be deemed to have occurred,
   regardless of any subsequent determination that one or more of the
   conditions thereto had not been met (although the occurrence of the
   Effective Date shall not release the Borrower from any liability or
   prevent the existence of an Event of Default based upon failure to
   satisfy one or more of the applicable conditions contained in
   Sections 5 and 6).
   
     13.11  Headings Descriptive.  The headings of the several
   sections and subsections of this Agreement are inserted for
   convenience only and shall not in any way affect the meaning or
   construction of any provision of this Agreement.
   
     13.12  Amendment or Waiver.  (a)  Neither this Agreement
   nor any other Credit Document nor any terms hereof or thereof may
   be changed, waived, discharged or terminated unless such change,
   waiver, discharge or termination is in writing signed by the
   Borrower and the Required Banks; provided that no such change,
   waiver, discharge or termination shall, without the consent of each
   Bank (with Obligations of the respective types in the case of
   following clause (i)):  (i) extend the final scheduled maturity of any
   Loan or Note or extend the stated maturity of any Letter of Credit
   beyond the Revolving Loan Maturity Date, or reduce the rate or
   extend the time of payment of interest or Fees thereon, or reduce
   the principal amount thereof; (ii) release all or substantially all of
   the Collateral (except as expressly provided in the Security
   Documents); (iii) amend, modify or waive any provision of this Section
   13.12; (iv) reduce the percentage specified in, or otherwise modify,
   the definition of Required Banks (it being understood that, with the
   consent of the Required Banks, additional extensions of credit
   pursuant to this Agreement may be included in the determination of
   the Required Banks on substantially the same basis as the extensions
   of Revolving Loan Commitments were included on the Effective
   Date); or (v) consent to the assignment or transfer by the Borrower
   of any of their rights and obligations under this Agreement;
   provided further, that no such change, waiver, discharge or termination
   shall:  (w) increase the Revolving Loan Commitment of any Bank
   over the amount thereof then in effect (it being understood that a
   waiver of any conditions precedent, covenants, Defaults or Events
   of Default or of a mandatory reduction in the Total Revolving Loan
   Commitment or of a mandatory prepayment shall not constitute an
   increase of the Revolving Loan Commitment of any Bank, and that
   an increase in the available portion of the Revolving Loan Commitment
   of any Bank shall not constitute an increase in the Revolving
   Loan Commitment of such Bank) without the consent of such Bank;
   (x) without the consent of Paribas, amend, modify or waive any
   provision of Section 2 or alter its rights or obligations with respect
   to Letters of Credit or Swingline Loans; or (y) without the consent
   of the Agent, amend, modify or waive any provision of Section 12
   or any other provision relating to the rights or obligations of the
   Agent; or (z) without the consent of the Collateral Agent, amend,
   modify or waive any provision of Section 12 or any other provision
   relating to the rights or obligations of the Collateral Agent.

   discharge or termination to any of the provisions of this Agreement
   as contemplated by clause (a)(i) through (v), inclusive, of the first
   proviso to Section 13.12(a), the consent of the Required Banks is
   obtained but the consent of one or more of such other Banks whose
   consent is required is not obtained, then the Borrower shall have the
   right to replace each such non-consenting Bank or Banks (so long
   as all non-consenting Banks are so replaced) with one or more
   Replacement Banks pursuant to Section 1.13 so long as at the time
   of such replacement, each such Replacement Bank consents to the
   proposed  change, waiver, discharge or termination, provided that
   the Borrower shall not have the right to replace a Bank solely as a
   result of the exercise of such Bank's rights (and the withholding of
   any required consent by such Bank) pursuant to the second proviso
   to Section 13.12(a).
   
     13.13  Survival.  All indemnities set forth herein including,
   without limitation, in Sections 1.10, 1.11, 2.06, 4.04, 8.15, 12.06
   and 13.01 shall survive the execution and delivery of this
   Agreement and the Notes and the making and repayment of the
   Loans and Letters of Credit.
   
     13.14  Domicile of Loans.  Each Bank may transfer and
   carry its Loans at, to or for the account of any office, Subsidiary or
   Affiliate of such Bank.  Notwithstanding anything to the contrary
   contained herein, to the extent that a transfer of Loans pursuant to
   this Section 13.14 would, at the time of such transfer, result in
   increased costs under Section 1.10, 1.11 or 4.04 from those being
   charged by the respective Bank prior to such transfer, then the
   Borrower shall not be obligated to pay such increased costs
   (although the Borrower shall be obligated to pay any increased costs
   of the type described above resulting from changes after the date of
   the respective transfer).
   
     13.15  Waiver of Jury Trial.  Each of the Parties to this
   Agreement hereby irrevocably waives all rights to a trial by jury in
   any action, proceeding or counterclaim arising out of or relating to
   this Agreement, the other Credit Documents or the transactions
   contemplated hereby or thereby.
   
     13.16  Interest Rate Limitation.  Notwithstanding anything
   contained in this Agreement or in the Notes to the contrary, if at
   any time the applicable interest rate, together with all fees and
   charges which are treated as interest under applicable law
   (collectively, the "Charges"), as provided for herein or in any other
   document executed in connection herewith, or otherwise contracted
   for, charged, received, taken or reserved by any Bank, shall exceed
   the maximum lawful rate (the "Maximum Rate") which may be
   contracted for, charged, taken, received or reserved by such Bank
   in accordance with applicable law, the rate of interest payable under

                                           Exhibit 10.2

           STOCK OPTION AGREEMENT



     THIS STOCK OPTION AGREEMENT is made as
of the 27th day of February, 1996, between Unilab
Corporation, a Delaware corporation (hereinafter called the
"Corporation"), and Andrew H. Baker, a key employee of
the Corporation (hereinafter called the "Option Holder").

     1.  Grant of Option.   (a) In accordance with the
Stock Option Program for Key Executives adopted by the
Corporation's Board of Directors, the Corporation hereby
grants to the Option Holder the right and option, hereinafter
called the "Option", to purchase an aggregate of 60,000
shares (the "Shares") of the Corporation's $0.01 par value
common stock (such number being subject to adjustment as
provided in paragraph 7 hereof), on the terms and
conditions herein set forth.  Such Option shall vest as
follows: Twenty-Five (25%) Percent of the Option herein
granted (for up to 15,000 shares) shall vest and may be
exercised on or after February 27, 1997; Twenty-Five
(25%) Percent of the Option herein granted (for up to
15,000 shares) shall vest and may be exercised on or after
February 27, 1998; Twenty-Five (25%) Percent of the
Option herein granted (for up to 15,000 shares) shall vest
and may be exercised on or after February 27, 1999;
Twenty-Five (25%) Percent of the Option herein granted
(for up to 15,000 shares) shall vest and may be exercised on
or after February 27, 2000 (unless terminated earlier
pursuant to paragraph 6 hereof).

     (b)  Notwithstanding anything stated in Section
1(a) above, no Option may be exercised by the option
Holder unless and until a stock option and performance
incentive plan for employees is submitted to and approved
by stockholders of the Corporation at the Corporation's
1996 Annual Meeting of Stockholders, or otherwise at a
Special Meeting of Stockholders duly called for such
purpose.  If such a stock option and performance incentive
plan for employees is not approved by the Corporation's
stockholders at such Annual or special Meeting, the option
granted herein shall be rescinded and cancelled, effective as
of the date of such meeting.

     2.  Purchase Price.  The purchase price of the Shares
covered by the Option shall be two  and three-sixteenths
dollars ($2.1875) per Share.

     3.  Term of Option.  Subject to paragraph 8 hereof,
the Option granted hereby shall be exercisable as to a
portion of the total Shares in accordance with paragraph 1. 
The Option Holder's right to exercise the aforementioned
Option shall expire ten (10) years from the date hereof. 
Unless terminated earlier pursuant to paragraph 6 hereof,
any Option not exercised within such time specified of the
date hereof shall terminate.

     4.  Nontransferability.  The Option shall not be
transferable otherwise than (i) by will or the laws of descent
and distribution and (ii) to parents, siblings, spouses or
children of the Option Holder or to any trust or similar
device intended for any of such persons' respective benefit
(a "Permitted Transferee"), and the Option may be
exercised, during the lifetime of the Option Holder, only by
him or such Permittee Transferree.  More particularly (but
without limiting the generality of the foregoing), the Option
may not be assigned, transferred (except as provided
herein), pledged, or hypothecated in any way, shall not be
assignable by operation of law, and shall not be subject to
execution, attachment, or similar process.   Any attempted
assignment, transfer, pledge, hypothecation or other
disposition of the Option contrary to the provisions hereof,
and the levy of any execution, attachment, or similar
process upon the Option shall be null and void and without
effect.

     5.  Disclosure and Risk.  The Option Holder
represents and warrants to the Corporation as follows:

     (a)  The Shares will be acquired by the Option
     Holder for the Option Holder's own account, for
     investment 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").

     (b)  As of the date of the grant and of exercise,
     because of his position with the Corporation, and as
     a result of inquiries made by him and information
     furnished to him by the Corporation, Option Holder
     has and will have all information necessary for him
     to make an informed investment decision.

     Each certificate representing the Shares shall, if
applicable, be endorsed with the following or a substantially
similar legend:

     "THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
     SECURITIES ACT'), AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED OR 
     HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION
     STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, OR THE
     CORPORATION RECEIVES AN OPINION OF COUNSEL FOR THE HOLDER OF
     THESE SECURITIES, REASONABLY SATISFACTORY TO THE
     CORPORATION, STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT OR
     HYPOTHECATION MAY BE MADE PURSUANT TO RULE 144,
     PROMULGATED UNDER THE SECURITIES ACT, OR IS OTHERWISE
     EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY
     REQUIREMENTS OF SUCH ACT AND APPLICABLE STATE SECURITIES
     LAWS."

     The Corporation need not allow a transfer of any of
the Shares unless one of the conditions specified in the
foregoing legend is satisfied.  The Corporation may also
instruct its transfer agent not to allow the transfer of any of
the Shares unless one of the conditions specified in the
foregoing legend is satisfied.  

     Any legend endorsed on a certificate pursuant to the
foregoing language and the stop transfer instructions with
respect to such Shares shall be removed and the Corporation
shall promptly issue a certificate without such legend to the
holder thereof if the Shares are registered under the
Securities Act and a prospectus meeting the requirements of
Section 10 of the Securities Act is available or if the holder
provides the Corporation with an opinion of counsel for
such holder of the Shares reasonably satisfactory to the
Corporation, to the effect that a public sale, transfer or
assignment of such Shares may be made without
registration.

     6.  Termination of Employment; Death.  

     (a)  In the event that the Option Holder shall
     cease to be an employee of the Corporation or any of
     its subsidiaries for any reason whatsoever, the
     Option may be exercised by the Option Holder (to
     the extent that the Option Holder shall have been
     entitled to do so as of the date of his termination of
     employment with the Corporation or any of its
     subsidiaries) at any time within 365 days after such
     termination but in any event not later than the date of
     expiration of the Option term.  So long as the Option
     Holder shall continue to be an employee of the
     Corporation or any of its subsidiaries, the Option
     shall not be affected by any change of duties or
     position.  Nothing in this Option Agreement shall
     confer upon the Option Holder any right to continue
     as an employee of the Corporation or any of its
     subsidiaries.

     (b)  In the event that the Option Holder dies prior
     to exercising all or any portion of the Option, the
     Option may be exercised by the estate of the Option
     Holder (to the extent that the Option Holder shall
     have been entitled to do so) at any time within 365
     days after the death of the Option Holder, but in any
     event not later than the date of expiration of the
     Option term.

     7.  Changes in Capital Structure.  If all or any
portion of the Option shall be exercised subsequent to any
share dividend, split-up, recapitalization, merger,
consolidation, combination or exchange of shares,
separation, reorganization, or liquidation occurring after the
date hereof, as a result of which shares of any class shall be
issued in respect of outstanding Shares or Shares shall be
changed into the same or a different number of shares of the
same or another class or classes, the person or persons
exercising the Option shall receive, for the aggregate price
paid upon such exercise, the aggregate number and class of
shares which, if the Shares (as authorized at the date hereof)
had been purchased at the date hereof for the same
aggregate price (on the basis of the price per share set forth
in paragraph 2 hereof) and had not been disposed of, such
person or persons would be holding at the time of such
exercise  as a result of such purchase and all such share
dividends, split-ups, recapitalizations, mergers,
consolidations, combinations or exchanges of shares,
separations, reorganizations, or liquidations; provided,
however, that no fractional shares shall be issued upon any
such exercise, and the aggregate price paid shall be
appropriately reduced on account of any fractional share not
issued.  In no event shall any adjustments  be made to the
Option as a result of the issuance or redemption of securities
of the Corporation for cash or other consideration, or upon
the exercise of any conversion rights of any securities of the
Corporation.

     8.  Method of Exercising Option.  Subject to the
terms and conditions of this Option Agreement, the Option
may be exercised by written notice to the Secretary of the
Corporation, at its principal office or such other location as
may be designated by the Secretary of the Corporation. 
Such notice shall state the election to exercise the Option
and the number of Shares in respect of which it is being
exercised, and shall be signed by the person or persons so
exercising the Option.  The notice of election shall be
accompanied by this Agreement and payment of the full
purchase price for the Shares being purchased.  The
Corporation shall deliver a certificate or certificates
representing Shares as soon as practicable after the notice of
election has been received.  In the event the Option shall be
exercised by any person or persons other than the Option
Holder, the notice of election shall be accompanied by
appropriate proof of the right of such person or persons to
exercise the Option.  All Shares that shall be purchased
upon the exercise of the Option as provided herein shall be
fully paid and nonassessable.

     9.   Mergers, Recapitalizations and Dissolutions. 
As long as Optionee is an employee of the Corporation or
any of its subsidiaries, the "acquisition" of the Corporation
by another entity or a "change in control" of the
Corporation shall cause each outstanding option:  (i) in the
event of an acquisition, to become an option to purchase
shares of the acquiring entity, for the balance of the term of
the option without regard to any nonsatisfied vesting
provisions or condition precedent which may be contained
in paragraph 1 of this Agreement, at a price and for a
number of shares as is consistent with the acquisition terms;
and (ii) in the event of a change in control, to become
exercisable in whole or in part, without regard to any
vesting provisions or condition precedent which may be
contained in paragraph 1 of this Agreement.  The
"acquisition" of the Corporation by another entity shall be
defined to be either a merger or consolidation with an
acquiring entity (or subsidiary or affiliate thereof) in which
the Corporation is not the surviving entity or in which the
Corporation becomes a subsidiary of an acquiring entity; the
sale of substantially all of the Corporation's assets; or the
dissolution or liquidation of the Corporation.  For purposes
of this paragraph, a "change in control" shall mean a change
of control of a nature that would be required to be reported
in response to Item 1(a) of the Current Report on Form 8-K,
pursuant to Section 13 or 15(d) of the Securities Exchange
Act of 1934 (the "Exchange Act"); provided that, without
limitation, such a change in control shall be deemed to have
occurred at such time as any "person", within the meaning
of Section 14(d) of the Exchange Act, is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under the
Exchange Act), directly or indirectly, of 30% or more of the
outstanding capital stock of the Corporation.

     10.  Optionee Not a Shareholder.  The Option
Holder under this Option, as such, shall not be entitled by
any reason of this Option to any rights whatsoever as a
shareholder of the Corporation.

     11.  General Provisions.  

     (a)  The Corporation shall at all times during the
     term of the Option reserve and keep available such
     number of Shares as will be sufficient to satisfy the
     requirements of this Option Agreement, shall pay all
     fees and expenses necessarily incurred by the
     Corporation in connection therewith, and shall use
     its best efforts to comply with all laws and
     regulations which, in the reasonable opinion of
     counsel for the Corporation, are applicable thereto.

     (b)  This Agreement shall be governed by and
     construed in accordance with the laws of the State of
     Delaware other than its conflicts of laws provisions.

     (c)  Any notice to be given hereunder by either
     party to the other shall be in writing and shall be
     given either by personal delivery or by mail,
     registered or certified, postage prepaid, return
     receipt requested, addressed to the other party at the
     respective addresses set forth below their signatures
     to this Agreement, or at any other address as such
     party may hereafter specify in writing.

     (d)  This Agreement sets forth the entire
     agreement of the parties concerning the subject
     matter hereto, and no other representations or
     warranties, express or implied, other than those
     contained herein, and no amendments or
     modifications hereto, shall be binding unless made in
     writing and signed by the parties hereto.

     (e)  The waiver by either party of a breach of any
     term or provision of this Agreement shall not
     operate or be construed as a waiver of a subsequent
     breach of the same provision or of the breach of any
     other term or provision of this Agreement.

     (f)  As used herein, the masculine gender shall
     include the feminine and the neuter genders, the
     neuter shall include the masculine and the feminine
     genders, the singular shall include the plural, and the
     plural shall include the singular.

     (g)  The headings in this Agreement are solely for
     convenience of reference and shall be given no effect
     in the construction or interpretation of this
     Agreement.

     (h)  The invalidity or enforceability of any
     provision of this Agreement shall not affect the
     validity or enforceability of any other provision of
     this Agreement, which shall remain in full force and
     effect.
  
     IN WITNESS WHEREOF, the Corporation has
caused this Option Agreement to be duly executed by its
officer thereunto duly authorized, and the Option Holder has
hereunto set his hand and seal, all as of the day and year
first above written.

           STOCK OPTION AGREEMENT



     THIS STOCK OPTION AGREEMENT is made as

Holder").

     1.  Grant of Option.  (a) In accordance with the
Stock Option Program for Key Executives adopted by the
Corporation's Board of Directors, the Corporation hereby
grants to the Option Holder the right and option, hereinafter
called the "Option", to purchase an aggregate of 35,000
shares (the "Shares") of the Corporation's $0.01 par value
common stock (such number being subject to adjustment as
provided in paragraph 7 hereof), on the terms and

(25%) Percent of the Option herein granted (for up to 8,750
shares) shall vest and may be exercised on or after February
27, 2000 (unless terminated earlier pursuant to paragraph 6
hereof).

     (b)  Notwithstanding anything stated in Section
1(a) above, no Option may be exercised by the Option
Holder unless and until a stock option and performance
incentive plan for employees is submitted to and approved
by stockholders of the Corporation at the Corporation's
1996 Annual Meeting of Stockholders, or otherwise at a
Special Meeting of Stockholders duly called for such
purpose.  If such a stock option and performance incentive
plan for employees is not approved by the Corporation's
stockholders at such Annual or special Meeting, the option
granted herein shall be rescinded and cancelled, effective as
of the date of such meeting.

     2.  Purchase Price.  The purchase price of the Shares
covered by the Option shall be two and three-sixteenths
dollars ($2.1875) per Share.

     3.  Term of Option.  Subject to paragraph 8 hereof,
the Option granted hereby shall be exercisable as to a
portion of the total Shares in accordance with paragraph 1. 
The Option Holder's right to exercise the aforementioned
Option shall expire ten (10) years from the date hereof. 
Unless terminated earlier pursuant to paragraph 6 hereof,
any Option not exercised within such time specified of the
date hereof shall terminate.

     4.  Nontransferability.  The Option shall not be
transferable otherwise than (i) by will or the laws of descent
and distribution and (ii) to parents, siblings, spouses or
children of the Option Holder or to any trust or similar
device intended for any of such persons' respective benefit
(a "Permitted Transferee"), and the Option may be
exercised, during the lifetime of the Option Holder, only by
him or such Permittee Transferree.  More particularly (but
without limiting the generality of the foregoing), the Option
may not be assigned, transferred (except as provided
herein), pledged, or hypothecated in any way, shall not be
assignable by operation of law, and shall not be subject to
execution, attachment, or similar process.   Any attempted
assignment, transfer, pledge, hypothecation or other
disposition of the Option contrary to the provisions hereof,
and the levy of any execution, attachment, or similar
process upon the Option shall be null and void and without
effect.

     5.  Disclosure and Risk.  The Option Holder
represents and warrants to the Corporation as follows:

     (a)  The Shares will be acquired by the Option
     Holder for the Option Holder's own account, for
     investment 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").

     (b)  As of the date of the grant and of exercise,
     because of his position with the Corporation, and as
     a result of inquiries made by him and information
     furnished to him by the Corporation, Option Holder
     has and will have all information necessary for him
     to make an informed investment decision.

     Each certificate representing the Shares shall, if
applicable, be endorsed with the following or a substantially
similar legend:

     "THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
     SECURITIES ACT'), AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED OR 
     HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION
     STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, OR THE
     CORPORATION RECEIVES AN OPINION OF COUNSEL FOR THE HOLDER OF
     THESE SECURITIES, REASONABLY SATISFACTORY TO THE
     CORPORATION, STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT OR
     HYPOTHECATION MAY BE MADE PURSUANT TO RULE 144,
     PROMULGATED UNDER THE SECURITIES ACT, OR IS OTHERWISE
     EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY
     REQUIREMENTS OF SUCH ACT AND APPLICABLE STATE SECURITIES
     LAWS."

     The Corporation need not allow a transfer of any of
the Shares unless one of the conditions specified in the
foregoing legend is satisfied.  The Corporation may also
instruct its transfer agent not to allow the transfer of any of
the Shares unless one of the conditions specified in the
foregoing legend is satisfied.  

     Any legend endorsed on a certificate pursuant to the
foregoing language and the stop transfer instructions with
respect to such Shares shall be removed and the Corporation
shall promptly issue a certificate without such legend to the
holder thereof if the Shares are registered under the
Securities Act and a prospectus meeting the requirements of
Section 10 of the Securities Act is available or if the holder
provides the Corporation with an opinion of counsel for
such holder of the Shares reasonably satisfactory to the
Corporation, to the effect that a public sale, transfer or
assignment of such Shares may be made without
registration.

     6.  Termination of Employment; Death.  

     (a)  In the event that the Option Holder shall
     cease to be an employee of the Corporation or any of
     its subsidiaries for any reason whatsoever, the
     Option may be exercised by the Option Holder (to
     the extent that the Option Holder shall have been
     entitled to do so as of the date of his termination of
     employment with the Corporation or any of its
     subsidiaries) at any time within 365 days after such
     termination but in any event not later than the date of
     expiration of the Option term.  So long as the Option
     Holder shall continue to be an employee of the
     Corporation or any of its subsidiaries, the Option
     shall not be affected by any change of duties or
     position.  Nothing in this Option Agreement shall
     confer upon the Option Holder any right to continue
     as an employee of the Corporation or any of its
     subsidiaries.

     (b)  In the event that the Option Holder dies prior
     to exercising all or any portion of the Option, the
     Option may be exercised by the estate of the Option
     Holder (to the extent that the Option Holder shall
     have been entitled to do so) at any time within 365
     days after the death of the Option Holder, but in any
     event not later than the date of expiration of the
     Option term.

     7.  Changes in Capital Structure.  If all or any
portion of the Option shall be exercised subsequent to any
share dividend, split-up, recapitalization, merger,
consolidation, combination or exchange of shares,
separation, reorganization, or liquidation occurring after the
date hereof, as a result of which shares of any class shall be
issued in respect of outstanding Shares or Shares shall be
changed into the same or a different number of shares of the
same or another class or classes, the person or persons
exercising the Option shall receive, for the aggregate price
paid upon such exercise, the aggregate number and class of
shares which, if the Shares (as authorized at the date hereof)
had been purchased at the date hereof for the same
aggregate price (on the basis of the price per share set forth
in paragraph 2 hereof) and had not been disposed of, such
person or persons would be holding at the time of such
exercise  as a result of such purchase and all such share
dividends, split-ups, recapitalizations, mergers,
consolidations, combinations or exchanges of shares,
separations, reorganizations, or liquidations; provided,
however, that no fractional shares shall be issued upon any
such exercise, and the aggregate price paid shall be
appropriately reduced on account of any fractional share not
issued.  In no event shall any adjustments  be made to the
Option as a result of the issuance or redemption of securities
of the Corporation for cash or other consideration, or upon
the exercise of any conversion rights of any securities of the
Corporation.

     8.  Method of Exercising Option.  Subject to the
terms and conditions of this Option Agreement, the Option
may be exercised by written notice to the Secretary of the
Corporation, at its principal office or such other location as
may be designated by the Secretary of the Corporation. 
Such notice shall state the election to exercise the Option
and the number of Shares in respect of which it is being
exercised, and shall be signed by the person or persons so
exercising the Option.  The notice of election shall be
accompanied by this Agreement and payment of the full
purchase price for the Shares being purchased.  The
Corporation shall deliver a certificate or certificates
representing Shares as soon as practicable after the notice of
election has been received.  In the event the Option shall be
exercised by any person or persons other than the Option
Holder, the notice of election shall be accompanied by
appropriate proof of the right of such person or persons to
exercise the Option.  All Shares that shall be purchased
upon the exercise of the Option as provided herein shall be
fully paid and nonassessable.

     9.   Mergers, Recapitalizations and Dissolutions. 
As long as Optionee is an employee of the Corporation or
any of its subsidiaries, the "acquisition" of the Corporation
by another entity or a "change in control" of the
Corporation shall cause each outstanding option:  (i) in the
event of an acquisition, to become an option to purchase
shares of the acquiring entity, for the balance of the term of
the option without regard to any nonsatisfied vesting
provisions or condition precedent which may be contained
in paragraph 1 of this Agreement, at a price and for a
number of shares as is consistent with the acquisition terms;
and (ii) in the event of a change in control, to become
exercisable in whole or in part, without regard to any
vesting provisions or condition precedent which may be
contained in paragraph 1 of this Agreement.  The
"acquisition" of the Corporation by another entity shall be
defined to be either a merger or consolidation with an
acquiring entity (or subsidiary or affiliate thereof) in which
the Corporation is not the surviving entity or in which the
Corporation becomes a subsidiary of an acquiring entity; the
sale of substantially all of the Corporation's assets; or the
dissolution or liquidation of the Corporation.  For purposes
of this paragraph, a "change in control" shall mean a change
of control of a nature that would be required to be reported
in response to Item 1(a) of the Current Report on Form 8-K,
pursuant to Section 13 or 15(d) of the Securities Exchange
Act of 1934 (the "Exchange Act"); provided that, without
limitation, such a change in control shall be deemed to have
occurred at such time as any "person", within the meaning
of Section 14(d) of the Exchange Act, is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under the
Exchange Act), directly or indirectly, of 30% or more of the
outstanding capital stock of the Corporation.

     10.  Optionee Not a Shareholder.  The Option
Holder under this Option, as such, shall not be entitled by
any reason of this Option to any rights whatsoever as a
shareholder of the Corporation.

     11.  General Provisions.  

     (a)  The Corporation shall at all times during the
     term of the Option reserve and keep available such
     number of Shares as will be sufficient to satisfy the
     requirements of this Option Agreement, shall pay all
     fees and expenses necessarily incurred by the
     Corporation in connection therewith, and shall use
     its best efforts to comply with all laws and
     regulations which, in the reasonable opinion of
     counsel for the Corporation, are applicable thereto.

     (b)  This Agreement shall be governed by and
     construed in accordance with the laws of the State of
     Delaware other than its conflicts of laws provisions.

     (c)  Any notice to be given hereunder by either
     party to the other shall be in writing and shall be
     given either by personal delivery or by mail,
     registered or certified, postage prepaid, return
     receipt requested, addressed to the other party at the
     respective addresses set forth below their signatures
     to this Agreement, or at any other address as such
     party may hereafter specify in writing.

     (d)  This Agreement sets forth the entire
     agreement of the parties concerning the subject
     matter hereto, and no other representations or
     warranties, express or implied, other than those
     contained herein, and no amendments or
     modifications hereto, shall be binding unless made in
     writing and signed by the parties hereto.

     (e)  The waiver by either party of a breach of any
     term or provision of this Agreement shall not
     operate or be construed as a waiver of a subsequent
     breach of the same provision or of the breach of any
     other term or provision of this Agreement.

     (f)  As used herein, the masculine gender shall
     include the feminine and the neuter genders, the
     neuter shall include the masculine and the feminine
     genders, the singular shall include the plural, and the
     plural shall include the singular.

     (g)  The headings in this Agreement are solely for
     convenience of reference and shall be given no effect
     in the construction or interpretation of this
     Agreement.

     (h)  The invalidity or enforceability of any
     provision of this Agreement shall not affect the
     validity or enforceability of any other provision of
     this Agreement, which shall remain in full force and
     effect.

      IN WITNESS WHEREOF, the Corporation has
caused this Option Agreement to be duly executed by its
officer thereunto duly authorized, and the Option Holder has
hereunto set his hand and seal, all as of the day and year
first above written.

     UNILAB CORPORATION ANNOUNCES FIRST QUARTER RESULTS
     Tarzana, CA, April 30, 1996 -- Unilab Corporation (Nasdaq:ULAB)
announced today that net sales for the quarter ended March 31, 1996
increased 22% to $51.5 million from $42.2 million for the same period last
year.  The Company reported a net loss for the first quarter of 1996
of $5.3 million, or $0.15 per common share, which included a
previously announced extraordinary charge of $3.5 million for the
early extinguishment of debt resulting from its recently completed
$120 million senior note offering.  Excluding the effect of the
charge, the net loss would have been $1.9 million, or $0.05 per common
share.  Net income in the first quarter of 1995 was $0.6 million,
or $0.02 per share, which included a legal charge of $1.2 million.  

     Commenting on results, Unilab Chairman and Chief Executive
Officer Andrew Baker noted, "Unilab again experienced strong
growth in volume and sales.  This quarter's revenues improved
both sequentially and year-over-year, despite the rate of growth
being tempered by a more than 4% pricing decline resulting
primarily from third party reimbursement pressures including
Medicare.  Nonetheless, our core operations, excluding the MLN
business acquired last May, reported a healthy 8% increase in
revenue from continued market share gains in Southern California
and accelerating volume trends in our Northern California regions. 
Results also demonstrate that we are making important initial
progress towards reducing Unilab's cost structure. During the
quarter we managed to moderately lower expenses in key areas
while increasing specimen throughput, gaining increased operating
efficiencies from reduced staffing levels and implementing more
efficient supplies utilization."  

     Mr. Baker continued, "We are confident that our leadership
position and strategic focus will enable us to successfully manage
operations through this challenging market environment.  Despite
continued pricing pressure, we are proud of our strong sales
growth, balanced by our increasing attention to cost control and
more efficient utilization of our staffing and resources.  While we
still have significant strides to make, we are committed not only to
strengthening our competitive position, but to doing so profitably."
    
        Unilab Corporation is the largest provider of clinical
laboratory testing services in California through its primary testing
facilities in Los Angeles, San Jose and Sacramento and over 200
regional service and testing facilities located throughout the state.
