                               DIGENE CORPORATION
                         NOTES TO FINANCIAL STATEMENTS



1.  BASIS OF PRESENTATION

The financial statements for the three month and nine month periods ended March
31, 1997 and 1996 are unaudited and include all adjustments which, in the
opinion of management, are necessary to present fairly the results of
operations for the periods then ended.  All such adjustments are of a normal
recurring nature.  These financial statements should be read in conjunction
with the Annual Report on Form 10-K of Digene Corporation (the "Company") for
the year ended June 30, 1996, which includes financial statements and notes
thereto for the years ended June 30, 1996, 1995, and 1994.

The results of the Company's operations for any interim period are not
necessarily indicative of the results of the Company's operations for any other
interim period or for a full fiscal year.

2.  NET LOSS PER SHARE

The Company's net loss per share calculations are based on the weighted average
number of shares of Common Stock outstanding.  Pursuant to the requirements of
the Securities and Exchange Commission staff accounting bulletin No. 83, the
Company included the effect of the convertible Preferred Stock, Common Stock,
and warrants and options to purchase Common Stock in the weighted average
shares outstanding for the three and nine month periods ended March 31, 1996.
However, for the three and nine month periods ended March 31, 1997, the Company
is required to calculate the weighted average shares outstanding pursuant to
APB 15 and thus the net loss per share for the periods is not comparable.  APB
15 requires that shares of Common Stock issuable upon the exercise of stock
options and warrants or conversion of convertible Preferred Stock are included
in the weighted average shares outstanding only if the effect of their
inclusion is dilutive.  The Company has not included such shares of Common
Stock in its weighted average shares outstanding since the effect is
anti-dilutive.  If the Company had calculated the weighted average shares
outstanding for the three months and nine months ended March 31, 1996 in
accordance with APB 15, the net loss per share would have been $1.62 and $4.60
per share, respectively, and the weighted average shares outstanding would have
been 374,775 and 371,034, respectively.

In February 1997, the Financial Accounting Standards Board issued Statement No.
128, Earnings Per Share, which is required to be adopted in the Company's
fiscal 1998 financial statements.  At that time, the Company will be required
to change the method currently used to compute earnings per share and to
restate all prior periods.  Under the new requirements for calculating  primary
earnings per share, the dilutive effect of stock options will be excluded.  The
impact of Statement No. 128 on the calculation of primary and fully diluted
earnings per share for the three and nine month periods ended March 31, 1997
and 1996 is not expected to be material.

3.  SIGNIFICANT EVENTS

Effective February 1, 1997, the Company entered into two agreements (the
"Agency Agreement" and the "Customer Transfer Agreement," collectively the
"Agreements") with Murex Diagnostics Corporation, a distributor ("Murex"), to
create a Digene-direct European sales operation for the Company's sexually
transmitted disease business.  Under the Agreements, the Company will begin
selling its Hybrid Capture(R) human papillomavirus ("HPV") DNA test directly in
Europe using Murex's distribution infrastructure.  The Agreements provide for a
transition period during which the administrative infrastructure will be agreed
to and established.  During this transition period, the Company is recording
its transactions, for purposes of transfer of title, consistent with a prior
distribution agreement (the "Distribution Agreement") with Murex, which
Distribution Agreement remains in effect to cover the distribution of the
Company's non-HPV products in areas outside the territory established by the
Agreements.  Prior to February 1, 1997, pursuant to the Distribution Agreement,
Murex had been acting as the exclusive European distributor in designated
non-US territories for the Company's HPV test and other of the Company's
products.  Under the Agreements, Murex will act as the exclusive agent for the
Company in designated European and Eastern European countries (the "Territory")
for a period of five years during which Murex will receive selling service fees
and a percentage of the Company's HPV revenues in the Territory.  In connection
with the Agreements, the Company capitalized approximately $2.5 million for the
acquisition of Murex's HPV business assets. The Company issued promissory notes
in the aggregate amount of $1,702,750 and paid $1.0 million to Murex for the
HPV business assets during the quarter ended March 31, 1997. The Company is
amortizing the HPV business assets over five years, the term of the Agency
Agreement.  In addition, the Company agreed to pay set up costs, selling
service fees and a percentage of Digene's HPV revenues in the Territory. 
Certain of these costs have been expensed as selling and general and
administrative expenses in the three months ended March 31, 1997 and will
continue to be expensed as such during the term of the Agency Agreement.  All
other Digene products (except the Company's HPV products) exclusively
distributed by Murex in Europe and Eastern Europe will not be affected by the
Agreements.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

FORWARD LOOKING STATEMENTS

Statements regarding the Company's expectations as to financial results and
other aspects of its business set forth below or otherwise made in writing or
orally by the Company may constitute forward looking statements within the
meaning of the Private Securities Litigation Reform Act of 1995.  Although the
Company believes that its expectations are based on reasonable assumptions
within the bounds of its knowledge of its business and operations, there can be
no assurance that actual results will not differ materially from its
expectations.  Factors which  could cause actual results to differ from
expectations include, but are not limited to, uncertainty of future
profitability, uncertainty of market acceptance, dependence on a single product 
(its Hybrid Capture HPV DNA test), limited sales and marketing experience, the
creation of the Company's European direct sales operations, adequacy of third
party reimbursement, competition, extent of government regulations, and the
uncertainty regarding

patents and proprietary rights and technological obsolescence.

RESULTS OF OPERATIONS

Product sales increased to $2,418,000 and $6,237,000 for the three and nine
month periods ending March 31, 1997, respectively, from $1,596,000 and
$4,464,000 for the corresponding periods of the prior year.  The increase was
due, primarily, to increased sales of the Company's Hybrid Capture products,
partially offset by declines in revenues related to the discontinuance of the
Company's radioactive DNA test in December 1995.  Declines in equipment sales
also partially offset the increase in the product sales for the nine month
period.

Research and development contract revenues increased to $100,000 and $494,000
for the three and nine month periods ending March 31, 1997, respectively, from
$89,000 and $293,000 for the corresponding periods of the prior year.  The
fiscal year-to-date increase was due primarily to new contracts.

Cost of product sales increased to $885,000 and $2,433,000 for the three and
nine month periods ending March 31, 1997, respectively, from $700,000 and
$2,133,000 for the corresponding periods of the prior year.  Gross margin on
product sales increased to 63% and 61% for the three and nine month periods
ended March 31, 1997, respectively, from 56% and 52% for the corresponding
periods of the prior year.  This increase was due primarily to increases in
unit pricing, overhead absorption, and sales of higher-margin Hybrid Capture
HPV DNA products, and decreases in sales of lower-margin products, such as
equipment.

Research and development expenses increased to $1,050,000 and $2,785,000 for
the three and nine month periods ending March 31, 1997, respectively, from
$657,000 and $1,767,000 for the corresponding periods of the prior year.  The
increase was due to increases in clinical trials activity, and to the hiring of
additional research and development personnel and the related incidental
expenses to support the Company's research and development efforts to develop
additional tests using the Hybrid Capture technology, and to improve the
sensitivity and ease of use of that technology.

Selling and marketing expenses increased to $1,120,000 and $2,976,000, or 46%
and 48% of revenues from product sales, for the three and nine month periods
ending March 31, 1997, respectively, from $439,000 and $1,263,000, or 28% and
28% of revenues from product sales, for the corresponding periods of the prior
year.  The increase was due to substantial increases in sales and marketing
programs and to the hiring of additional selling and marketing personnel and
related expenses to support the Company's revenue growth plans, as well as
increased commissions and other selling costs directly related to the growth in
product sales.

General and administrative expenses increased to $1,454,000 and $3,214,000, or
58% and 48% of total revenues, for the three and nine month periods ending
March 31, 1997, respectively, from $404,000 and $1,018,000, or 24% and 21% of
total revenues, for the corresponding periods of the prior year.  The increase
was due primarily to the recognition of set-up costs associated with the
Company's expansion into the European market, as well as the hiring of
additional administrative personnel and the related expenses to support the

Company's requirements as a publicly traded company and to meet the
revenue growth objectives of the Company.  In addition, general and
administrative expenses increased during the nine month period as a result of
the formation of Digene do Brasil, a majority-owned subsidiary.

Amortization of intangible assets increased to $91,000 and decreased to
$108,000 for the three and nine month periods ending March 31, 1997,
respectively, from $82,000 and $260,000 for the corresponding periods of the
prior year.  The increase during the three month period is attributable to
amortization expense related to the acquisition of intangible business
assets associated with the Company's expansion into the European market, 
partially offset by decreases related to intangible assets becoming fully 
amortized during the periods begin compared.  The decrease during the nine 
month period is due to certain intangible assets becoming fully amortized 
during the periods being compared, partially offset by increases attributable 
to the amortization expense related to the acquisition of the aforementioned 
intangible European business assets.

Interest income increased to $374,000 and $1,206,000 for the three and nine
month periods ending March 31, 1997, respectively, from $7,000 and $24,000 for
the corresponding periods of the prior year.  These increases were due
primarily to the investment of substantially all of the net proceeds from the
Company's initial public offering, which was completed in May, 1996.

Interest expense decreased to $32,000 and $36,000 for the three and nine month
periods ended March 31, 1997, respectively, from $54,000 and $163,000 for the
corresponding periods of the prior year.  These decreases were due to the
repayment of notes payable related to the acquisition of the Molecular  
Diagnostics Division of Life Technologies, Incorporated, consummated in 1990,
partially offset by interest expense on notes payable related to the Company's
expansion into the European market.


LIQUIDITY AND CAPITAL RESOURCES

Since inception, the Company's expenses have significantly exceeded its
revenues, resulting in an accumulated deficit of approximately $23,015,000 at
March 31, 1997.  The Company has  funded its operations primarily through the
sale of equity securities.  The Company experienced negative cash flows from
operations of $5,093,000 and $1,203,000 for the nine months ended March 31,
1997, and 1996, respectively.

Capital expenditures increased to $776,000 for the nine months ended March 31,
1997 from $223,000 for the same period in 1996, due primarily to the
acquisition of leasehold improvements and related furniture and equipment
associated with the expansion of the Company's Beltsville, Maryland facility
and to additional laboratory and computer equipment purchases.






                                       8
<PAGE>   11



The Company does not have any bank financing arrangements.  The Company's
indebtedness consists of notes payable in the principal amount of $1,920,000
related to its expansion into the European market, notes payable in the
principal amount of $84,000 to former stockholders of the Company, and notes
payable in the principal amount of $52,000 related to leasehold improvements.

The Company has incurred negative cash flows from operations since its
inception, and has expended, and expects to continue to expend in the future,
substantial funds to complete its planned product development efforts, expand
its sales and marketing activities and scale up its manufacturing capabilities.
The Company expects that its existing capital resources will be adequate to
fund the Company's operations through fiscal 1998.  No assurances can be given
that there will be no changes in the Company that would consume a significant
amount of its available resources before that time.  The Company's future
capital requirements and the adequacy of available funds will depend on
numerous factors, including the successful commercialization of its Hybrid
Capture HPV DNA test, progress in its product development efforts, the
magnitude and scope of such efforts, progress with preclinical studies and
clinical trials, the cost and timing of manufacturing scale-up, the creation of
the Company's direct European sales operations, the development of effective
sales and marketing activities, the cost of filing, prosecuting, defending and
enforcing patent claims and other intellectual property rights, competing
technological and market developments, and the development of strategic
alliances for the marketing of its products.  To the extent that the Company's
existing capital resources and funds generated from the Company's operations
are insufficient to meet current or planned operating requirements, the Company
will be required to obtain additional funds through equity or debt financing,
strategic alliances with corporate partners and others, or through other
sources.  The Company does not have any committed sources of additional
financing, and there can be no assurance that additional funding, if necessary,
will be available on acceptable terms, if at all.  If adequate funds are not
available, the Company may be required to delay, scale-back or eliminate
certain aspects of its operations or attempt to obtain funds through
arrangements with collaborative partners or others that may require the Company
to relinquish rights to certain of its technologies, product candidates,
products or potential markets.  If adequate funds are  not available, the
Company's business, financial condition and results of operations will be
materially and adversely effected.

In February 1997, the Financial Accounting Standards Board issued Statement No.
128, Earnings Per Share, which is required to be adopted in the Company's
fiscal 1998 financial statements.  At that time, the Company will be required
to change the method currently used to compute earnings per share and to
restate all prior periods.  Under the new requirements for calculating primary
earnings per share, the dilutive effect of stock options will be excluded.  The
impact of Statement No. 128 on the calculation of primary and fully diluted
earnings per share for the three and nine month periods ended March 31, 1997
and 1996 is not expected to be material.

                    AGENCY AND SALES REPRESENTATION AGREEMENT



This serves to record the agreement (the "Agreement"), effective as of February
1, 1997, between Digene Corporation ("Digene") of 9000 Virginia Manor Road,
Beltsville, MD 20705, U.S.A. and Murex Diagnostics Corporation ("Murex") of
White Park House, White Park Road, Bridgetown Barbados (each of Digene and Murex
a "Party" and collectively the "Parties") relating to the consignment inventory
holding, agency arrangements, distribution and sale of the diagnostic products
supplied by Digene as specified in Schedule I hereto (the "Products") or
subsequently added by agreement in writing between the Parties to customers in
those countries specified in Schedule II hereto (the "Territory"). Unless the
context specifically provides otherwise, all currency amounts, including "$",
set forth herein shall refer to United States currency.

1.       Definitions.

         1.1      "Affiliate" shall mean any Person that controls, is controlled
                  by or is under common control with Murex or Digene, as the
                  context may require. For purposes of this definition "control"
                  shall mean: (a) in the case of corporate entities, direct or
                  indirect ownership of at least fifty percent (50%) of the
                  stock or shares entitled to vote for the election of
                  directors; and (b) in the case of non-corporate entities,
                  direct or indirect ownership of at least fifty percent (50%)
                  of the equity interest with the power to direct the management
                  and policies of such non-corporate entities.

         1.2      "Distribution Agreement" shall have the meaning ascribed to
                  such term in Section 3.2 hereof.

         1.3      "Effective Date" shall mean February 1, 1997.

         1.4      "HPV" shall mean Human Papillomavirus.

         1.5      "Net Sales" shall mean, with respect to each Product, the
                  gross amount invoiced on behalf of Digene in connection with
                  sales of Products under this Agreement, expressed in US
                  Dollars, less the sum of the following:

                  1.5.1    sales, tariff duties and/or use or value added taxes
                           actually paid on behalf of customers by Murex or
                           Digene, as the case may be, in

REQUEST.  REDACTED MATERIAL IS BRACKETED AND HAS BEEN FILED SEPARATELY WITH THE
SECURITIES AND EXCHANGE COMMISSION.



                           connection with the manufacture, importation, use or
                           sale of such Product;

                  1.5.2    actual costs of packaging, insurance, freight,
                           storage and transportation paid on behalf of the
                           purchaser;

                  1.5.3    allowances actually made (and not merely reserved or
                           accrued) for any goods which are sold to customers
                           and are spoiled, damaged, outdated or returned after
                           they are shipped by Murex; or

                  1.5.4    refunds or allowances actually made on account of
                           retroactive price reductions.

                  Any Net Sales not expressed in United States dollars shall be
                  converted to such currency using the monthly weighted average
                  exchange rate calculated using the daily exchange rates
                  published in The Wall Street Journal for the period over which
                  such average is calculated.

         1.6      "Nonaffiliate" shall mean any Person that is not an Affiliate
                  of Murex or Digene, or both, as the context may require.

         1.7      "Person" shall mean an individual, a corporation, a
                  partnership, an association, a joint stock company, a trust,
                  any unincorporated organization or a government or political
                  subdivision thereof.

         1.8      "Work With" shall mean to provide reasonable assistance, to
                  consult, to offer advice and to take other reasonable steps
                  designed to help resolve technical or quality or customer
                  problems and to provide a professional, unified image to
                  customers, and timely cooperation in the execution of
                  marketing programs, pricing or policy changes; provided,
                  however, that "Work With" shall not mean incurring any capital
                  expenditure or incurring any expense other than as set forth
                  in this Agreement. For the purposes of this definition, a
                  failure to "Work With" shall include a habitual neglect or
                  failure to perform the activities outlined in this Agreement
                  over a commercially reasonable period of time, failure to act
                  in good faith, on a timely basis at the request of the other
                  Party, or acting in front of customers in a way which is not
                  consistent with the reasonable operating standards of Murex or
                  Digene, as the case may be. A failure to "Work With" must be
                  documented in writing which may include, without limitation,
                  the use of sworn affidavits as documentary evidence of a
                  failure to Work With. The Party receiving any notification of
                  a failure to Work With the other Party shall have sixty (60)
                  days to cure such failure. If such failure is not cured at the
                  end of such 60-day period the notifying Party may terminate
                  this Agreement for cause pursuant to Section 12 hereof.

2.       Appointment.

         2.1      Digene hereby appoints Murex in the Territory with effect from
                  February 1, 1997 for the provision of agency services as
                  specified in Section 4 hereto (the "Agency Services") or as
                  subsequently amended by agreement in writing between the
                  Parties.

         2.2      Digene hereby appoints Murex in the Territory with effect from
                  February 1, 1997 for the holding of consignment inventory of
                  Products (the "Inventory Holding Services") and Murex agrees
                  to act in that capacity subject to the terms and conditions
                  set forth in Appendix A, the "Distribution Inventory Holding
                  Agreement", attached hereto and made a part hereof. The
                  Parties agree there shall be a transition period of three (3)
                  months to establish the inventory consignment systems
                  contemplated by this Agreement. In such transition period,
                  Murex will book inventory transactions to credit sales to
                  Digene's account on a monthly basis.

         2.3      Digene hereby appoints Murex in the Territory with effect from
                  February 1, 1997 to provide selling services as specified in
                  Section 6 hereto (the "Selling Services") for the Products and
                  Murex agrees to act in that capacity subject to the terms and
                  conditions as set forth herein.

         2.4      Murex may appoint any of its Affiliates, distributors or
                  agents to undertake some or all of its obligations hereunder
                  and Murex shall ensure that any such Affiliate, distributor or
                  agent abides by all the terms and conditions of this Agreement
                  insofar as they relate to the promotion, sale, distribution or
                  inventory holding of Products in the countries of operation of
                  said Affiliate, distributor or agent.

                  2.4.1    Murex shall provide to Digene a list of all current
                           distributors and agents for the Territory which list
                           is attached hereto as Schedule IV. In the event Murex
                           elects to sub-appoint any other distributor or agent
                           to act on behalf of Murex under any of the
                           appointments set forth in Section 2.1, 2.2 or 2.3
                           above, Murex shall first notify Digene in writing in
                           advance. After such notification, Digene shall have
                           the right to accept or reject Murex's
                           sub-appointment. In the event Digene accepts Murex's
                           sub-appointment, Digene shall have the right to
                           review the agreement or other arrangement between
                           Murex and such distributor or agent in order to
                           confirm that Digene's interests will be protected,
                           and if necessary, in Digene's sole discretion,
                           provide for Digene to enter into an agreement
                           directly with such agent or distributor. In the event
                           Digene enters into an agreement with such distributor
                           or agent, Murex, at Murex's option, will have no
                           obligation

                           to provide Agency Services to such distributor or
                           agent as appointed by Digene, but will provide
                           services to Digene, at Digene's cost for expenses
                           pre-approved by Digene, to reasonably support Digene
                           during a transition period. The Parties agree there
                           shall be a transition period of three (3) months to
                           establish the agency and other systems contemplated
                           by this Agreement.

                  2.4.2    In the event Murex elects to sub-appoint an Affiliate
                           to undertake some or all of Murex's obligations
                           hereunder, the Agency Fees payable pursuant to
                           Section 5.2 hereof shall be calculated to reflect the
                           sales of Products from such Affiliate to the
                           third-party end purchaser or to a Nonaffiliate
                           distributor or agent. In the event Murex elects to
                           sub-appoint a Nonaffiliate distributor or agent to
                           undertake some or all of Murex's obligations
                           hereunder, the Agency Fees payable pursuant to
                           Section 5.2 hereof shall be calculated to reflect the
                           sales of Products by Murex to such Nonaffiliate
                           distributor or agent.

                  2.4.3    Provided that such termination does not directly
                           conflict with Murex's written contractual obligations
                           to such distributor or agent as of the Effective Date
                           or obligations pursuant to applicable law, if Digene
                           so chooses, at its sole discretion, Digene may
                           require that Murex terminate a Murex distributor or
                           agent upon 90 days written notice unless Digene and
                           the distributor or agent have agreed in writing to
                           other provisions, in which case, those provisions
                           will prevail. In the case of such a termination or
                           election not to accept a Murex agent or distributor,
                           no Agency Fees (as defined in Section 5.2 hereof)
                           will be due to Murex for servicing such distributor
                           or agent and Murex will have no obligation to provide
                           Agency Services to such distributor or agent as
                           appointed by Digene, but will provide services to
                           Digene, at Digene's cost, for expenses pre-approved
                           by Digene to reasonably support Digene during a
                           transition period. Any termination pursuant to this
                           Section 2.4.3 will not reduce the Selling Services
                           fees payable in the then current budget year as
                           determined in accordance with Section 8.4 hereof.

         2.5      Murex and Digene will create an Operating Committee which will
                  be responsible for: reviewing the overall business status of
                  the Parties with respect to this Agreement; resolving
                  operating issues which may develop from time to time;
                  finalizing and agreeing to program budgets; and approving
                  specific Standard Operating Procedures ("SOP's") for the
                  operation of the Agency Services, the Inventory Holding
                  Services and the Selling Services. The Operating Committee
                  shall initially consist of R. Peter Silveston and Lynwood
                  Bell, on behalf of Murex, and Evan Jones and Charles M.

                  the Products. In such case, Digene will be responsible for
                  expenses pre-approved by Digene for incremental regulatory
                  compliance costs. Murex shall notify Digene promptly of any

                  affecting the activities performed under this Agreement of

                  of all governmental or regulatory correspondence.

         6.2      In the event that Digene desires to appoint its own personnel
                  and desires such personnel to be based in the offices of Murex
                  or a Murex Affiliate in the Territory, Murex agrees, at
                  Digene's request, to pay the salary, any pension contributions
                  and expenses of such personnel as authorized by Digene and
                  Digene agrees to reimburse Murex for such authorized payments

                  begin paying any of its own personnel operating under this

                  be unreasonably withheld and shall be based upon factors
                  including availability of office space and facilities. In the
                  event that Digene personnel utilize office space on a
                  full-time basis within a Murex or Murex Affiliate facility as
                  agreed by Murex, Digene shall pay Murex on a monthly basis
                  according to Section 8 of this Agreement a proportion of

                  expenses, as applicable, at the rate to be agreed upon by
                  Murex and Digene based on the allocated cost of an individual
                  full time equivalent (total office costs divided by the
                  relevant full time equivalent value) (the "Facility Charge").
                  Murex shall have the right to increase the monthly Facility
                  Charge on January 1st of each year during the term of this
                  Agreement in line with the rate of inflation in each country
                  where Digene utilizes the office facilities of Murex or a
                  Murex Affiliate.

         6.4      Digene shall be responsible for payment to Murex on a monthly
                  basis according to Section 8 of this Agreement of all other
                  expenses incurred or authorized by Digene or its personnel and
                  paid by Murex or a Murex Affiliate.

         6.5      During the 90 day period following the Effective Date, Murex
                  shall, at the cost of Digene, carry on all necessary servicing
                  of certain luminometers and shakers (the "Equipment") used by
                  customers of Products in the Territory in the same manner in
                  which Murex has been providing such servicing to such
                  customers. Murex shall determine the aforesaid reasonable cost
                  for such Equipment servicing during said 90 day period and
                  Digene shall pay such costs in accordance with Section 8 of

                  maintenance of such accounts and payment systems. The Parties
                  agree to Work With each other as needed on a case by case
                  basis to prevent either Party from losing business as a result
                  of the implementation of the activities contemplated by this
                  Section 8.1.

         8.2      Murex shall provide Digene within 30 days of each month end a
                  statement detailing and reconciling the Digene Receivables.
                  Murex shall also invoice Digene within 30 days of each month
                  end for the costs and expenses reimbursement to be paid by
                  Digene to Murex under this Agreement, specifically arising
                  under Sections 2.4.1, 2.4.3, 4.5, 4.6, 4.11, 4.13, 4.14, 5.2,
                  6.2, 6.3, 6.4, 6.5, 6.6, 6.9, 7.1, 8.1 and Appendix A,
                  Sections 3.2 and 4 and not paid to the Murex Affiliates
                  directly pursuant to Section 8.1 hereof. Digene shall pay such
                  invoice in full within 30 days of receipt. Digene may, in its
                  discretion, at the request of Murex, authorize specific Murex
                  employees to have signatory power to withdraw funds from the
                  Digene account(s) established to reimburse Murex or its
                  Affiliates for costs and expenses incurred by Murex and its
                  Affiliates and prior approved by Digene arising from the
                  Agency Services, Inventory Holding Services and Selling
                  Services provided under this Agreement, and such authorization
                  by Digene shall not be unreasonably withheld. In the event
                  such authorization is provided and the Digene Receivables are
                  insufficient to cover the total invoice, Murex shall invoice
                  Digene for such shortfall and Digene shall pay such shortfall
                  invoice in full within 30 days of receipt.

         8.3      Murex and its Affiliates agree to use the same level of due
                  diligence to collect outstanding Digene Receivables as they
                  use to collect their own outstanding receivables. Digene shall
                  bear the cost of any bad debt incurred in the sale of Products
                  in the Territory; provided, however, that Digene shall perform
                  a quarterly reconciliation of all bad debt existing. Digene
                  reserves the right, following good faith discussions with
                  Murex, to invoice Murex for reimbursement of the Agency Fees
                  paid with respect to uncollected receivables less the
                  distribution and shipping costs incurred by Murex and
                  pertaining to such uncollected receivables, upon Digene's
                  having recognized and written off such uncollected receivables
                  for its own financial reporting purposes, and certifying the
                  same in writing to Murex, and Murex shall pay the invoice in
                  full within 30 days of receipt.

         8.4      Prior to January 1, 1998 and every year thereafter during the
                  term of this Agreement, Murex and Digene shall discuss and
                  agree to revisions in the level of Selling Services to be
                  provided in the following calendar year and the associated
                  costs payable by Digene to Murex. In the event that Digene has
                  not notified Murex of any change in the level of Selling
                  Services to be provided by Murex under Section 6 of this
                  Agreement prior to the end of any calendar year, then the
                  level of Selling Services shall continue at the level then set
                  and the associated Selling Services fees and related expenses
                  as set forth in Section 6 of this Agreement payable by Digene
                  to Murex shall remain at the then current level subject to an
                  increase in line with the rate of inflation in the country
                  where the Selling Services are performed. In the event the
                  Parties cannot agree on the level of Selling Services or
                  Selling Services fees in any given year during the term of
                  this Agreement then either Party shall be free to terminate
                  the use of Murex employees in the provision of Selling
                  Services as described in Section 6 of this Agreement. In such
                  event, the Selling Services fees set forth in Section 6.9 will
                  no longer be payable to Murex and Murex will no longer be
                  responsible for performing the Selling Services.

9.       Term.

         This Agreement shall become effective on February 1, 1997 and shall
         continue in full force and effect for a period of 5 years unless
         terminated earlier under Section 12 hereof. Unless this Agreement is
         terminated early under Section 12 hereof or is terminated at the end of
         the initial 5 year term by either Party giving to the other no less
         than six (6) months notice in writing, the term of the Agreement shall
         automatically continue until either Party serves six (6) months'
         written notice of termination on the other at any time thereafter.

10.      Relationship.

         This Agreement is personal to Murex and Digene and shall not be
         assigned or delegated by either Party without the prior written
         agreement of the other Party, except that Murex may assign any or all
         of its rights and delegate any or all of its obligations to one or more
         of its Affiliates, agents or distributors as provided herein; provided,
         however, that in such event, Murex shall guarantee and be responsible
         for the performance of such obligations by such Affiliate, agent or
         distributor.

11.      Confidentiality.

         11.1     From time to time, Digene may make available to Murex
                  information of a confidential nature (the "Digene Confidential
                  Information") including, but not limited to, medical and

                  Confidential Information and the Digene Market Information is

                  same care as it would exercise in the handling of its own
                  proprietary information. In no event shall the Digene

                  period of four (4) years from the date of termination or
                  expiration of this Agreement. Notwithstanding anything else in

                  provisions of this Section 14.1 and Digene's obligations under

         14.3     Notice and Defense of Third-Party Claims. If any action, claim
                  or proceeding shall be brought or asserted under this Section
                  14 against an indemnified party or any successor thereto (the
                  "Indemnified Person") in respect of which indemnity may be
                  sought under this Section 14 from an indemnifying person or
                  any successor thereto (the "Indemnifying Person"), the
                  Indemnified Person shall give prompt written notice of such
                  action or claim to the Indemnifying Person who shall assume
                  the defense thereof, including the employment of counsel
                  reasonably satisfactory to the Indemnified Person and the
                  payment of all expenses; the Indemnified Person shall have the
                  right to employ separate counsel in any of the foregoing
                  actions, claims or proceedings and to participate in the
                  defense thereof, but the fees and expenses of such counsel
                  shall be at the expense of the Indemnified Person unless both
                  the Indemnified Person and the Indemnifying Person are named
                  as parties and in the opinion of counsel for the Indemnified
                  Person common counsel would be inappropriate due to actual or
                  potential conflicts of interest between the Parties. In the
                  event that the Indemnifying Person, within ten days after
                  notice of any such action or claim, fails to assume the
                  defense thereof, the Indemnified Person shall have the right
                  to undertake the defense, compromise or settlement of such
                  action, claim or proceeding for the account of the
                  Indemnifying Person, subject to the right of the Indemnifying
                  Person to assume, at its expense, the defense of such action,
                  claim or proceeding with counsel reasonably satisfactory to
                  the Indemnified Person at any time prior to the settlement,
                  compromise or final determination thereof. Anything in this
                  Section 14 to the contrary notwithstanding, the Indemnifying
                  Person shall not, without the Indemnified Person's prior
                  written consent, settle or compromise any action or claim or
                  consent to the entry of any judgment with respect to any
                  action, claim or proceeding for anything other than money
                  damages paid by the Indemnifying Person. The Indemnifying
                  Person may, without the Indemnified Person's prior written
                  consent, settle or compromise any such action, claim or
                  proceeding or consent to entry of any judgment with respect to
                  any such action or claim that requires solely the payment of
                  money damages by the Indemnifying Person and that includes as
                  an unconditional term thereof the release by the claimant or
                  the plaintiff of the Indemnified Person from all liability
                  with respect to such action, claim or proceeding.

15.      Miscellaneous Provisions.

         15.1     Arbitration. Subject to the provisions of the Federal
                  Arbitration Act, 9 U.S.C. Section 1 et. seq., any claim,
                  controversy or dispute arising out of or relating to this
                  Agreement or any interpretation or breach thereof or
                  performance thereunder, including without limitation any
                  dispute concerning the scope of this arbitration provision,
                  shall be settled by submission to final and binding
                  arbitration ("Arbitration") for determination, without any
                  right by

                  any Party to a trial de novo in a court of competent
                  jurisdiction. The Arbitration and all pre-hearing, hearing,
                  post-hearing arbitration procedures shall be conducted in
                  accordance with the Commercial Arbitration Rules (the
                  "Commercial Rules") of the American Arbitration Association
                  (herein referred to as the "Association") as supplemented
                  hereby. The Arbitration hearing shall take place in
                  Washington, D.C. All pre-hearing and post-hearing matters and
                  procedures shall take place at such place and manner,
                  including telephonically, as shall be agreed by the Parties.
                  In the event the parties fail to reach agreement regarding the
                  foregoing, the chair of the Arbitration panel shall determine
                  the manner and location of such matters. In addition to the
                  Commercial Rules, the Parties shall also follow the procedures
                  described below:

                  15.1.1   The Party seeking Arbitration shall give notice of a
                           demand to arbitrate (herein referred to as the
                           "Demand") to the other Party and to the Association.
                           The Demand shall include (i) the nature of the claim
                           that is being asserted and the remedy or relief that
                           is requested, or the issues to be determined if no
                           claim is being asserted, (ii) a copy of this
                           arbitration provision, and (iii) unless the Parties
                           shall have otherwise agreed upon the mutual selection
                           of a single arbitrator, the designation of one
                           arbitrator, who shall have no prior or existing
                           personal or financial relationship with the
                           designating Party.

                  15.1.2   Within thirty (30) days after receipt of the Demand,
                           the other Party shall give notice (herein referred to
                           as the "Response") to the Party that demanded
                           arbitration, and to the Association, of (i) any
                           additional issues to be arbitrated, (ii) its answer
                           to the claims or issues raised by the Party that sent
                           the Demand, and (iii) its designation of a second
                           arbitrator, who shall have no prior or existing
                           personal or financial relationship with the
                           designating Party. The Response shall also set forth
                           all third party claims and the relief requested in
                           respect thereof that are intended to be asserted by
                           such Party providing the Response.

                  15.1.3   If a Response designating a second arbitrator is not
                           received within the above-mentioned thirty (30) day
                           period, the Association shall immediately designate
                           the second arbitrator.

                  15.1.4   The two arbitrators as designated pursuant to the
                           foregoing provision shall then designate a third
                           arbitrator within ten (10) days after the designation
                           of the second arbitrator. If the two arbitrators
                           cannot agree on the designation of the third
                           arbitrator

                           within the ten (10) day period allotted, the
                           Association shall designate the third arbitrator.
                           Such third arbitrator designated pursuant to this
                           Section 15.1.4 shall be the chair of the Arbitration
                           panel.

                  15.1.5   The Arbitration panel as designated above shall
                           proceed with the Arbitration by giving notice to all
                           Parties of its proceedings and hearings in accordance
                           with the Association's applicable procedures. Within
                           15 days after all three arbitrators have been
                           appointed or at such other time as shall be agreed by
                           the Parties, an initial meeting among the chair of
                           the Arbitration panel and counsel for the Parties
                           shall be held for the purpose of establishing a plan
                           for administration of the Arbitration, including: (i)
                           definition of issues; (ii) scope, timing and type of
                           discovery, which may at the discretion of the
                           arbitrators include production of documents in the
                           possession of the Parties, but may not, without the
                           consent of the Parties, include depositions; (iii)
                           exchange of documents and filing of detailed
                           statements of claims and pre-hearing memoranda; (iii)
                           schedule and place of hearings; and (iv) any other
                           matters that may promote the efficient, expeditious
                           and cost-effective conduct of the proceeding. The
                           substantive law of the State of Maryland shall be
                           applied by the arbitrators to the resolution of the
                           dispute, provided that the arbitrators shall base
                           their decision on the express terms, covenants and
                           conditions of this Agreement. The arbitrators shall
                           be bound to make specific findings of fact and reach
                           conclusions of law, based upon the submissions and
                           evidence of the Parties, and shall issue a written
                           decision explaining the basis for the decision and
                           award.

                  15.1.6   The Parties agree that the arbitrators shall have no
                           power to alter or modify any express provision of
                           this Agreement or to render any award which, by its
                           terms, effects any such alteration or modification.

                  15.1.7   Upon written demand to any Party to the Arbitration
                           for the production of documents and things (including
                           computer discs and data) reasonably related to the
                           issues being arbitrated, the Party upon which such
                           demand is made shall promptly produce, or make
                           available for inspection and copying, such documents
                           or things without the necessity of any action by the
                           arbitrators, provided, however, that no such demand
                           shall be effective if

                           made within the twenty (20) day period prior to the
                           first day of the Arbitration hearing.

                  15.1.8   Subject to the limitations imposed by Section 15.1.5,
                           the arbitrators shall have the power to grant any and
                           all relief and remedies, whether at law or in equity,
                           including provisional relief, that the courts in the
                           State of Maryland may grant and such other relief as
                           may be available under the Commercial Rules, other
                           than punitive damages. Any award of the arbitrators
                           shall include pre-award and post-award interest at
                           the applicable rate or rates under Maryland law. The
                           decision of the arbitrators shall be final and as an
                           "award"within the meaning of the Commercial Rules and
                           the Federal Arbitration Act and judgment upon the
                           arbitration award may be entered in the United States
                           District Courts of Maryland ("Maryland District
                           Courts") or any other court having jurisdiction, as
                           if it were a judgment of that court. The Parties to
                           this Agreement expressly consent to the jurisdiction
                           of the Association, including, without limitation,
                           reasonable attorney's fees and the Parties waive any
                           objection they may have as to jurisdiction and venue
                           regarding the Maryland District Courts.

                  15.1.9   The Arbitration panel is specifically authorized to
                           award attorney's fees and expenses to the prevailing
                           Party, as determined by the Arbitration panel.

         15.2     Force Majeure. Either Party shall be excused from any delay or
                  failure in performance hereunder caused by any labor dispute,
                  governmental requirement, act of God, earthquake, inability to
                  secure materials and transportation facilities, and other
                  causes beyond its control. If such delay, except for any such
                  delay caused by governmental regulations, shall continue for
                  more than 90 days, and 135 days in the case of Digene's
                  inability to deliver Products to customers, the Party injured
                  by the inability of the other Party to perform shall have the
                  right, upon written notice to the other Party, to terminate
                  this Agreement. If a delay or failure to perform hereunder
                  shall continue for more than 90 days, and 135 days in the case
                  of Digene's inability to deliver Products to customers and is
                  caused by any implementation of governmental restrictions or
                  regulations that make it commercially impossible for Digene to
                  sell the Products in the Territory, either Party injured by
                  the inability to perform under the Agreement shall have the
                  right, upon written notice to the other Party, to terminate
                  this Agreement. In the event a termination arising only under
                  the preceding sentence of this Section 15.2 occurs, Digene
                  shall not be responsible for any payments not then due and

                  required to pay the amounts set forth in Section 12.4 hereof,
                  as if there had been Termination for Cause by Digene.
                  Termination under this Section 15.2 shall not relieve either
                  Party of any payment obligation due and owing under this
                  Agreement or for liability for any breach hereunder.

         15.3     Entire Agreement.

                  This Agreement sets forth the entire agreement and
                  understanding between the Parties relative to the subject
                  matter contained herein and supersedes all other agreements,
                  oral and written, heretofore made between the Parties, with
                  respect to the subject matter herein. Any amendment hereto
                  must be in writing and signed by an authorized representative
                  of each of Digene and Murex.

                  hereunder, shall, except where specifically provided
                  otherwise, be given in writing, and delivered either by
                  personal delivery to the Party to whom notice is to be given,
                  or sent by registered mail or by an internationally recognized
                  express delivery service, addressed to the Party intended at
                  the address set forth below. The date of delivery in the case
                  of personal or mail delivery or the date upon which it is
                  deposited with the express delivery service in the case of
                  notice by express delivery service, shall be deemed to be the

         15.7     Records. Murex shall keep accurate and detailed records of all
                  sales of the Products, and Murex shall permit examination and
                  inspection of such records by authorized representatives of
                  Digene, no more than two times per calendar year, during usual

                  inspection of such information to an agreed independent
                  auditor, only to the extent such inspection may divulge
                  confidential information of Murex. In the event Murex
                  exercises its right to limit inspection to an auditor, written
                  records of sales not containing such confidential information
                  shall be supplied by Murex per the terms of Sections 4.13 and

                  without regard to conflicts of laws principles, applicable to

                  Agreement.

                  15.9.1   Press Releases. Each of Digene and Murex agree not to
                           announce this Agreement by press release or other
                           form of communication without the written approval of
                           the other Party.

                  15.9.2   Permitted Disclosure. The Parties agree to keep the
                           terms of this Agreement confidential with exception
                           of such information which in the opinion of counsel
                           to the disclosing party is required to be disclosed
                           by applicable law, rule, regulation or generally
                           accepted accounting practice, including any rules of

                           authorities or organizations on which the Parties or
                           their Affiliates are listed. Provided, however, that
                           in the event a Party or its Affiliate shall be
                           required to disclose any of the terms of this
                           Agreement, whether pursuant to subpoena, deposition,
                           interrogatory, or otherwise, or a Party or its
                           Affiliate shall otherwise propose to disclose any of

                                    requirements; and (ii) any Party shall be
                                    permitted to submit this Agreement as
                                    evidence in any proceeding in connection
                                    with any dispute between the Parties. The
                                    provisions of this Section 15.9.2 shall not
                                    restrict a Party from making any disclosure
                                    of any terms of this Agreement to the extent
                                    such terms become generally available to the
                                    public (other than as a result of a
                                    disclosure by such Party in violation of
                                    this Agreement), or restrict the ability of
                                    the Parties from making disclosure to the
                                    extent such disclosure is required for the
                                    effective undertaking by the Parties of
                                    their respective rights and obligations
                                    hereunder. By way of example and not in
                                    limitation of the foregoing, Murex shall be
                                    entitled to disclose to proposed customers
                                    the fact that it is acting as an authorized
                                    agent of Digene.

         15.10    Guaranty. International Murex Technologies Corporation shall,
                  subject to the consent of Bank of America, FSB (the "Bank"),
                  guarantee the payment obligations of Murex and its Affiliates
                  arising hereunder. Digene hereby consents to Murex's
                  disclosure to the Bank of such information pertaining to this
                  Agreement as is relevant to Murex's request for the Bank to
                  grant such consent.

         15.11    Severability. In case any one or more of the provisions or
                  parts of a provision contained in this Agreement shall for any
                  reason be held to be invalid, illegal or unenforceable in any
                  respect, such invalidity, illegality or unenforceability shall
                  not affect any other provision or part of a provision of this
                  Agreement, but this Agreement shall be reformed and construed
                  as if such invalid or illegal or unenforceable provision or
                  part of a provision had never been contained herein.

         15.12    Counterparts: Effectiveness of Agreement. This Agreement shall
                  be executed in counterparts, each of which shall be deemed an
                  original but both of which together shall constitute the same
                  instrument.

                    DISTRIBUTION INVENTORY HOLDING AGREEMENT
                              TERMS AND CONDITIONS


1.       Storage Facilities

         1.2      Inspection of the storage facilities by an authorized
                  representative of Digene shall be permitted at all reasonable
                  times on five (5) working days notice during Murex's normal
                  business hours.

         1.3      Digene shall inform Murex if, at any time, it is aware of any

                  Products.

         1.4      Murex shall ensure that the facilities and services provided
                  under this Agreement are compliant with those GMP and
                  governmental regulations which apply in the Territory and are
                  relevant to the performance of all activities contemplated by
                  this Agreement.

2.       Inventory Reporting

         Murex shall provide to Digene within 30 days of the end of every month

                  stores and with a statement to the effect that such Products
                  are the property of Digene, and, in addition, to the extent
                  space in Murex's facilities is available, segregate Digene's
                  Products from Murex's products within the facilities of Murex,

                  this Agreement, HPV Information means the Customer lists
                  relating to Customers in the Territory to whom Products have
                  been sold in the previous 12 months, lists of Customers to

                  use of its customer lists, the foregoing is not intended to
                  preclude Murex's ability to continue to use its customer
                  lists, which may include the HPV Information, for non-HPV
                  purposes in the Territory and anywhere in the world or for any
                  purpose outside the Territory in the countries as listed on
                  Schedule 3 attached hereto.

         2.2      Digene will pay Murex as consideration for the HPV Information

                  specified by Murex (the "Escrow Payment") in accordance with

                  date herewith (the "Escrow Agreement"), a form of which is
                  attached as Exhibit "A" to this Agreement. Murex will direct
                  the Escrow Agent (as defined in the Escrow Agreement) to
                  release the Escrow Payment to Murex on April 1, 1997, if Murex

                  The obligations evidenced by the [  ] Note and the [        ]
                  Note are primary obligations of Digene hereunder. If for any
                  reason the [  ] Note or the [      ] Note are held to be
                  invalid or unenforceable, or are not issued because the Escrow
                  Agreement is for any reason held to be invalid or
                  unenforceable, Digene agrees to make such payments as are set
                  forth in this Section 2.2 directly to Murex upon the
                  respective scheduled payment dates, notwithstanding such
                  invalidity or unenforceability, subject only to the
                  satisfaction of the conditions provided in Section 2.3 hereof.
                  The foregoing will only be applicable in the event of such
                  invalidity or unenforceability and will not require Digene to
                  make duplicate payments.

         2.3      The release to Murex of the [  ] Note and the [      ] Note
                  issued by Digene pursuant to Section 2.2 hereof are subject to
                  Digene having made Product sales in the Territory of a minimum
                  of US $[ ] per three month period in the most recent three
                  month period immediately preceding the release of the [  ]
                  Note or the [      ] Note, as applicable, for which sales
                  figures are available. If such minimum Product sales target
                  levels are not met in the three month period immediately
                  preceding the release of the [  ] Note or the [      ] Note,
                  as applicable, the Escrow Agent will be instructed by Murex to
                  release the [  ] Note or the [      ] Note, as applicable, to
                  Digene. Notwithstanding the aforesaid, if the three month
                  sales minimum referenced herein is not met due to any default
                  by Digene in the timely delivery of Product to customers in
                  the Territory or in the quantity and meeting the
                  specification, quality and performance claims of Digene, then
                  this Section 2.3 shall be of no effect.

         2.4      In the event conflicting instructions are given to the Escrow
                  Agent regarding the release from escrow of any of the Escrow
                  Payment, the [  ] Note or the [      ] Note as described in
                  Section 2.2, the Parties agree to submit any such dispute to
                  arbitration immediately, and to inform the Escrow Agent of
                  such arbitration proceeding.

3.       Miscellaneous.

         3.1      Arbitration. Subject to the provisions of the Federal
                  Arbitration Act, 9 U.S.C. Section 1 et. seq., any claim,

                  and binding arbitration ("Arbitration") for determination,
                  without any right by any Party to a trial de novo in a court
                  of competent jurisdiction. The Arbitration and all
                  pre-hearing, hearing, post-hearing arbitration procedures
                  shall be conducted in accordance with the Commercial
                  Arbitration Rules (the "Commercial Rules") of the American
                  Arbitration Association (herein referred to as the
                  "Association") as supplemented hereby. The Arbitration hearing
                  shall take place in Washington, D.C. All pre-hearing and
                  post-hearing matters and procedures shall take place at such
                  place and manner, including telephonically, as shall be agreed
                  by the Parties. In the event the parties fail to reach
                  agreement regarding the foregoing, the chair of the
                  Arbitration panel shall determine the manner and location of
                  such matters. In addition to the Commercial Rules, the Parties
                  shall also follow the procedures described below:

                  3.1.1    The Party seeking Arbitration shall give notice of a
                           demand to arbitrate (herein referred to as the
                           "Demand") to the other Party and to the Association.
                           The Demand shall include (i) the nature of the claim
                           that is being asserted and the remedy or relief that
                           is requested, or the issues to be determined if no
                           claim is being asserted, (ii) a copy of this
                           arbitration provision, and (iii) unless the Parties
                           shall have otherwise agreed upon the mutual selection
                           of a single arbitrator, the designation of one
                           arbitrator, who shall have no prior or existing
                           personal or financial relationship with the
                           designating Party.

                  3.1.2    Within thirty (30) days after receipt of the Demand,
                           the other Party shall give notice (herein referred to
                           as the "Response") to the Party that demanded
                           arbitration, and to the Association, of (i) any
                           additional issues to be arbitrated, (ii) its answer
                           to the claims or issues raised by the Party that sent
                           the Demand, and (iii) its designation of a second
                           arbitrator, who shall have no prior or existing
                           personal or financial relationship with the
                           designating Party.

                  3.1.3    If a Response designating a second arbitrator is not
                           received within the above-mentioned thirty (30) day
                           period, the Association shall immediately designate
                           the second arbitrator.

                  3.1.4    The two arbitrators as designated pursuant to the
                           foregoing provision shall then designate a third
                           arbitrator within ten (10) days after the designation
                           of the second arbitrator. If the two arbitrators
                           cannot agree on the designation of the third
                           arbitrator within the ten (10) day period allotted,
                           the Association shall designate the third arbitrator.
                           Such third

                           arbitrator designated pursuant to this Section 3.1.4
                           shall be the chair of the Arbitration panel.

                  3.1.5    The Arbitration panel as designated above shall
                           proceed with the Arbitration by giving notice to all
                           Parties of its proceedings and hearings in accordance
                           with the Association's applicable procedures. Within
                           15 days after all three arbitrators have been
                           appointed or at such other time as shall be agreed by
                           the Parties, an initial meeting among the chair of
                           the Arbitration panel and counsel for the Parties
                           shall be held for the purpose of establishing a plan
                           for administration of the Arbitration, including: (i)
                           definition of issues; (ii) scope, timing and type of
                           discovery, which may at the discretion of the
                           arbitrators include production of documents in the
                           possession of the Parties, but may not, without the
                           consent of the Parties, include depositions; (iii)
                           exchange of documents and filing of detailed
                           statements of claims and pre-hearing memoranda; (iii)
                           schedule and place of hearings; and (iv) any other
                           matters that may promote the efficient, expeditious
                           and cost-effective conduct of the proceeding. The
                           substantive law of the State of Maryland shall be
                           applied by the arbitrators to the resolution of the
                           dispute, provided that the arbitrators shall base
                           their decision on the express terms, covenants and
                           conditions of this Agreement. The arbitrators shall
                           be bound to make specific findings of fact and reach
                           conclusions of law, based upon the submissions and
                           evidence of the Parties, and shall issue a written
                           decision explaining the basis for the decision and
                           award. The arbitrators shall have the authority to
                           issue instructions to the Escrow Agent in connection
                           with any dispute pertaining to the Escrow Agreement.

                  3.1.6    The Parties agree that the arbitrators shall have no
                           power to alter or modify any express provision of
                           this Agreement or to render any award which, by its
                           terms, effects any such alteration or modification.

                  3.1.7    Upon written demand to any Party to the Arbitration
                           for the production of documents and things (including
                           computer discs and data) reasonably related to the
                           issues being arbitrated, the Party upon which such
                           demand is made shall promptly produce, or make
                           available for inspection and copying, such documents
                           or things without the necessity of any action by the
                           arbitrators, provided, however, that no such demand
                           shall be effective if made within the twenty (20) day
                           period prior to the first day of the Arbitration
                           hearing.

                           all relief and remedies, whether at law or in equity,
                           including provisional relief, that the courts in the

                           decision of the arbitrators shall be final and as an
                           "award"within the meaning of the Commercial Rules and

                           if it were a judgment of that court. The Parties to

                           of the Association, including, without limitation,
                           reasonable attorney's fees and the Parties waive any
                           objection they may have as to jurisdiction and venue
                           regarding the Maryland District Courts.

                  3.1.9    The Arbitration panel is specifically authorized to
                           award attorney's fees and expenses to the prevailing

         written request for the Escrow Funds ("Request for Funds") to the
         Escrow Agent and to the Company. Such Request for Funds shall certify
         that Murex has delivered to the Company the HPV Information.

                  (b) Disbursement of Funds. Unless the Escrow Agent shall have

         also be provided by the Company to Murex.

                  (c) Stop Order. Upon receipt of a Stop Order, the Escrow Agent
         shall withhold any disbursement of the Escrow Funds until the Escrow
         Agent receives written instructions from the Company directing the
         disbursement of the Escrow Funds, or until the Escrow Agent receives
         instructions from an arbitration panel or other tribunal in a
         proceeding to which Murex and the Company are parties, in accordance
         with the provisions of Paragraph 5 hereof.

         written request for Note B ("Request for Note B"), to the Escrow Agent
         and to the Company. Such Request for Note A and Request for Note B

         Section 2.3 of the Customer Transfer Agreement pertaining to the
         conditions for the release of Note A, or Note B, as applicable, have

         Murex on the eighteenth (18th) day following its receipt of a Request
         for Note B, but in no event earlier than [              ]. A
         "Non-Release Order" shall mean a written notice from the Company
         certifying that the requisite target sales levels, as described in
         Section 2.3 of the Customer Transfer Agreement, have not been met. Any
         Non-Release Order provided by the Company to the Escrow Agent under
         this Agreement must also be provided by the Company to Murex.

                  (f) Non-Release Order. Upon receipt of a Non-Release Order in
         respect of Note A or Note B, the Escrow Agent shall withhold any
         release of Note A or Note B, as applicable, until the Escrow Agent
         receives written instructions from the Company directing the release to
         Murex of Note A or Note B, as applicable, or until the Escrow Agent
         receives instructions from an arbitration panel or other tribunal in a
         proceeding to which Murex and the Company are parties, in accordance
         with the provisions of Paragraph 5 hereof.

                  (g) Release of Note A or Note B to Digene. In the event the
         requisite sales target levels, as set forth in Section 2.3 of the
         Customer Transfer Agreement, are not met in the time period prior to
         [          ] or [              ], as applicable, Murex shall provide
         written instructions to the Escrow Agent providing for the release of
         Note A or Note B, as applicable, to Digene. The Escrow Agent shall
         release Note A or Note B, as applicable, to Digene no later than the
         third (3rd) day following its receipt of such instructions from Murex.

                  (h) Interest. All interest earned on the Escrow Funds shall be
         added to the Escrow Funds and disbursed by the Escrow Agent with the
         Escrow Funds to the party entitled to the Escrow Funds.

         4. Termination of Escrow. Except as otherwise provided in Paragraph
5(d) hereof, the escrow arrangements provided for under this Agreement shall
terminate at the earlier to occur of (a) the release of the Escrow Funds,
together with all interest thereon, and the Notes in accordance with the
provisions of Paragraph 2 hereof or (b) the mutual agreement of Murex and the
Company to terminate this Agreement. In the event Murex and the Company elect to
terminate this Agreement, they shall provide the Escrow Agent with joint
instructions with respect to the disbursement of the Escrow Funds and the Notes
remaining in escrow, as applicable.

         5. Rights, Duties and Responsibilities of the Escrow Agent. It is

further agreed that:

REQUEST.  REDACTED MATERIAL IS BRACKETED AND HAS BEEN FILED SEPARATELY WITH THE
SECURITIES AND EXCHANGE COMMISSION.




                  (a) The Escrow Agent shall not be required to enforce the
         Customer Transfer Agreement, or any other agreement between the Company
         and Murex. In addition, the Escrow Agent shall not be responsible for
         the performance under or compliance by the Company or Murex of their
         respective obligations under this Agreement or for verifying the
         accuracy or completeness of any certificate, demand or other document
         submitted to it by either the Company or Murex or both.

                  (b) The Escrow Agent shall have the right to act in reliance
         upon any document, instrument or signature believed by it to be genuine
         and to assume that any person purporting to give notice or instructions
         pursuant to this Agreement or in connection with any transaction to
         which this Agreement relates has been duly authorized to do so. The
         Escrow Agent shall not be obligated to make any inquiry as to the
         authority, capacity, existence or identity of any person purporting to
         give such notice or instructions.

                  (c) Disbursement of Escrow Funds and release of the Notes by
         the Escrow Agent from escrow under this Agreement shall be to Murex or
         the Company, as the case may be, to the address or the account set
         forth in the notice of payment, and shall not be to any third party.

                  (d) In the event that the Escrow Agent shall be uncertain as
         to its duties or rights hereunder or shall receive instructions with
         respect to the Escrow Funds or Notes which, in its sole opinion, are in
         conflict with either other instructions received by it or any provision
         of this Agreement, or shall receive an objection to the making of any
         requested disbursement, the Escrow Agent shall be entitled to hold the
         Escrow Funds and/or the Notes pending the resolution of such
         uncertainty, conflict, dispute or objection, to the Escrow Agent's sole
         satisfaction, by written agreement of the Company and Murex or by final
         judgment of an arbitration panel or other tribunal of competent
         jurisdiction; or the Escrow Agent, at its option, may deposit the
         Escrow Funds and the Notes in the registry of a court or arbitration
         tribunal of competent jurisdiction in a proceeding to which all parties
         in interest are joined.

                  (e) The Escrow Agent shall not be liable for any action taken
         or omitted by it in good faith and believed by it to be authorized or
         within the rights or powers conferred upon it by this Agreement, and
         may consult with counsel of its own choice and shall have full and
         complete authorization and protection for any action taken or suffered
         by it hereunder in good faith and in accordance with the opinion of
         such counsel.

                  (f) The Company acknowledges that the Escrow Agent has
         represented affiliates of Murex in connection with corporate and
         litigation matters, and may continue to represent Murex or its
         affiliates in the future.

         6. Fees. The Escrow Agent shall receive an annual fee of $1,000 for
acting as the escrow agent hereunder, payable upon commencement of this
Agreement and each

SECURITIES AND EXCHANGE COMMISSION.




anniversary date hereof, and shall be reimbursed for all expenses incurred in
connection with its services under this Agreement. The Company and Murex shall
each be responsible for fifty (50%) percent of such fees and expenses.

         7. Resignation. The Escrow Agent may resign and be discharged from its
duties or obligations hereunder by giving notice in writing of such resignation
specifying a date when such resignation shall take effect. In the case of the
Escrow Agent's resignation or discharge, its only duty shall be to hold and
dispose of the Escrow Funds and the Notes in accordance with the original
provisions of this Agreement until a successor escrow agent shall be appointed
and written notice of the name and address of such successor escrow agent shall
be given to the original Escrow Agent by the Company and Murex, whereupon the
Escrow Agent's only duty shall be to pay or transfer over to the successor
escrow agent the Escrow Funds and Notes remaining in escrow and to deliver a
statement reflecting any previous disbursements in accordance with the terms of
this Agreement.

         8. Indemnification and Contribution. The Company and Murex each agrees
to indemnify the Escrow Agent for and hold it harmless against any loss,
liability or expense (including reasonable attorneys' fees) incurred without
negligence or bad faith on the part of the Escrow Agent arising out of or in
connection with its entering into this Agreement and carrying out its duties
hereunder, including the costs and expenses of defending itself against any
claim of liability hereunder.

         9. Governing Law. This Agreement shall be construed in accordance with
and governed by the laws of the State of New York (without giving effect to
conflicts of laws). Any proceeding or arbitration brought by the Escrow Agent
under this Agreement may be instituted in the City of New York, State of New
York, and neither the Company nor Murex shall object to such jurisdiction.

         10. Assignment. This Agreement shall be binding upon the parties hereto
and their respective successors, assigns, heirs and administrators; provided,
however, that any assignment or transfer by the Company or Murex of its rights
under this Agreement or with respect to the Escrow Funds and the Notes shall be
void as against the Escrow Agent unless: (a) notice thereof shall be given to
the Escrow Agent, and (b) the Escrow Agent shall have consented to such
assignment and transfer.

         11. Notices. All notices, requests and other materials required to be
given in connection with this Agreement shall be in writing and delivered in
person or by internationally recognized overnight courier delivery service, sent
by facsimile or sent by registered or certified mail, return receipt requested,

                  FOR VALUE RECEIVED, Digene Corporation ("Maker") hereby
promises to pay to the order of Murex Diagnostics Corporation or its assigns
(the "Payee") the principal sum of [   ] Dollars ($[   ]), payable in

                  The payments to be made hereunder by Maker shall be payable to
the Payee on such dates and in such amounts as follows:


                        [                           ]

         The Maker of this Note shall be entitled to prepay this Note, without

presentation, or notice of any kind, any and all of the indebtedness represented
by this Note may be declared and thereupon immediately shall mature and become

right to accelerate the maturity of the indebtedness hereunder, or indulgence
granted, from time to time, shall in no event be considered as a waiver of such
right of acceleration or prevent the Payee from exercising such right.

         Maker will from time to time and at all times hereafter upon every
reasonable request of the Payee do, execute, acknowledge and deliver or cause to
be done, executed, acknowledged and delivered all such further acts,

other relief under any applicable bankruptcy laws or insolvency laws, state,
federal, or other, within the United States or outside the United States, now or

be done, executed, acknowledged and delivered all such further acts,

                  Agreement and except as set forth in this Section 2, MBL and

                  contained herein, or in the Agency and Sales Representation
                  Agreement shall be deemed to terminate or otherwise reduce the
                  rights of MBL or any of its Affiliates to (i) sell or
                  otherwise distribute any of the Non-Exclusive Products in the
                  Territory in connection with non-HPV Digene products,
                  including to HPV Exclusive Product customers, or to non-HPV
                  Exclusive Products customers as such rights are set forth in
                  the Digene/Murex Agreements, or (ii) to sell or otherwise
                  distribute Products outside of the Territory pursuant to such
                  Digene/Murex Agreements.

         2.2      Digene is also hereby granted the right to request that MBL

                  Schedule I attached hereto in any of the remaining territories
                  as listed in Exhibit B of the Distribution Agreement, provided
                  that Digene provides six (6) months advance notice to MBL of
                  the exercise of such right and further provided that such
                  request shall not conflict with the terms and provisions in
                  effect as of the Effective Date in any existing agency or
                  distribution agreement MBL or its Affiliates utilize to sell
                  or distribute the Products. In the event MBL or its Affiliates
                  elect to enter into any new agency or distribution agreement
                  with respect to the Products, MBL shall first notify Digene in
                  writing in advance. After such notification, Digene shall have
                  the right to accept or reject MBL's (or such MBL's
                  Affiliates') execution of such agreement. Digene shall have
                  the right to review the agreement or other arrangement between
                  MBL and such distributor or agent in order to confirm that
                  Digene's interests will be protected, and if necessary, in
                  Digene's sole discretion, provide for Digene to enter into an


                                        2

                  agreement directly with such agent or distributor. In such
                  event, MBL and MBL's Affiliates will have no obligation to
                  provide agency or other services under any agreements with
                  Digene or its Affiliates for servicing such distributor or
                  agent, except for services provided, at Digene's cost, to
                  reasonably support Digene during a transition period.

3.       Digene is relieved of any obligation under Sections 1.3 and 1.4 of the
         Distribution Agreement.

4.       Miscellaneous

         4.1      Arbitration. Subject to the provisions of the Federal
                  Arbitration Act, 9 U.S.C. Section 1 et. seq., any claim,
                  controversy or dispute arising out of or relating to this
                  Agreement or any interpretation or breach thereof or
                  performance thereunder, including without limitation any
                  dispute concerning the scope of this arbitration provision,
                  shall be settled by submission to final and binding
                  arbitration ("Arbitration") for determination, without any
                  right by any Party to a trial de novo in a court of competent
                  jurisdiction. The Arbitration and all pre-hearing, hearing,
                  post-hearing arbitration procedures shall be conducted in

                  (herein referred to as the "Association") as supplemented
                  hereby. The Arbitration hearing shall take place in
                  Washington, D.C. All pre-hearing and post-hearing matters and
                  procedures shall take place at such place and manner,
                  including telephonically, as shall be agreed by the Parties.
                  In the event the parties fail to reach agreement regarding the
                  foregoing, the chair of the Arbitration panel shall determine
                  the manner and location of such matters. In addition to the
                  Commercial Rules, the Parties shall also follow the procedures
                  described below:

                  4.1.1    The Party seeking Arbitration shall give notice of a
                           demand to arbitrate (herein referred to as the
                           "Demand") to the other Party and to the Association.
                           The Demand shall include (i) the nature of the claim
                           that is being asserted and the remedy or relief that
                           is requested, or the issues to be determined if no
                           claim is being asserted, (ii) a copy of this
                           arbitration provision, and (iii) unless the Parties
                           shall have otherwise agreed upon the mutual selection
                           of a single arbitrator, the designation of one
                           arbitrator, who shall have no prior or existing
                           personal or financial relationship with the
                           designating Party.

                  4.1.2    Within thirty (30) days after receipt of the Demand,
                           the other Party shall give notice (herein referred to
                           as the "Response") to the Party that demanded
                           arbitration, and to the Association, of (i) any
                           additional issues to be arbitrated, (ii) its answer
                           to the claims or issues raised by

                           the Party that sent the Demand, and (iii) its
                           designation of a second arbitrator, who shall have no
                           prior or existing personal or financial relationship
                           with the designating Party.

                  4.1.3    If a Response designating a second arbitrator is not
                           received within the above-mentioned thirty (30) day
                           period, the Association shall immediately designate
                           the second arbitrator.

                  4.1.4    The two arbitrators as designated pursuant to the
                           foregoing provision shall then designate a third
                           arbitrator within ten (10) days after the designation
                           of the second arbitrator. If the two arbitrators
                           cannot agree on the designation of the third
                           arbitrator within the ten (10) day period allotted,
                           the Association shall designate the third arbitrator.
                           Such third arbitrator designated pursuant to this
                           Section 4.1.4 shall be the chair of the Arbitration
                           panel.

                  4.1.5    The Arbitration panel as designated above shall
                           proceed with the Arbitration by giving notice to all
                           Parties of its proceedings and hearings in accordance
                           with the Association's applicable procedures. Within
                           15 days after all three arbitrators have been
                           appointed or at such other time as shall be agreed by
                           the Parties, an initial meeting among the chair of
                           the Arbitration panel and counsel for the Parties
                           shall be held for the purpose of establishing a plan
                           for administration of the Arbitration, including: (i)
                           definition of issues; (ii) scope, timing and type of
                           discovery, which may at the discretion of the
                           arbitrators include production of documents in the
                           possession of the Parties, but may not, without the
                           consent of the Parties, include depositions; (iii)
                           exchange of documents and filing of detailed
                           statements of claims and pre-hearing memoranda; (iii)
                           schedule and place of hearings; and (iv) any other
                           matters that may promote the efficient, expeditious
                           and cost-effective conduct of the proceeding. The
                           substantive law of the State of Maryland shall be
                           applied by the arbitrators to the resolution of the
                           dispute, provided that the arbitrators shall base
                           their decision on the express terms, covenants and
                           conditions of this Agreement. The arbitrators shall
                           be bound to make specific findings of fact and reach
                           conclusions of law, based upon the submissions and
                           evidence of the Parties, and shall issue a written
                           decision explaining the basis for the decision and
                           award.

                  4.1.6    The Parties agree that the arbitrators shall have no
                           power to alter or modify any express provision of
                           this Agreement or to render any award which, by its
                           terms, effects any such alteration or modification.

                           issues being arbitrated, the Party upon which such
                           demand is made shall promptly produce, or make
                           available for inspection and copying, such documents
                           or things without the necessity of any action by the
                           arbitrators, provided, however, that no such demand
                           shall be effective if made within the twenty (20) day
                           period prior to the first day of the Arbitration
                           hearing.

                  4.1.8    Subject to the limitations imposed by Section 4.1.5,
                           the arbitrators shall have the power to grant any and
                           all relief and remedies, whether at law or in equity,
                           including provisional relief, that the courts in the
                           State of Maryland may grant and such other relief as
                           may be available under the Commercial Rules, other
                           than punitive damages. Any award of the arbitrators
                           shall include pre-award and post-award interest at
                           the applicable rate or rates under Maryland law. The
                           decision of the arbitrators shall be final and as an
                           "award" within the meaning of the Commercial Rules
                           and the Federal Arbitration Act and judgment upon the
                           arbitration award may be entered in the United States
                           District Courts of Maryland ("Maryland District
                           Courts") or any other court having jurisdiction, as
                           if it were a judgment of that court. The Parties to
                           this Agreement expressly consent to the jurisdiction
                           of the Association, including, without limitation,
                           reasonable attorney's fees and the Parties waive any
                           objection they may have as to jurisdiction and venue
                           regarding the Maryland District Courts.

                  4.1.9    The Arbitration panel is specifically authorized to
                           award attorney's fees and expenses to the prevailing
                           Party, as determined by the Arbitration panel.

         4.2      Entire Agreement.

                  as amended by this First Amendment thereto, set forth the

         4.5      Waivers. The waiver by either Party of any breach or alleged
                  breach of any provision hereunder shall not be construed to be

                  writing.

         4.6      Governing Law. This First Amendment, and all of the rights and

                  construed under the law of the State of Maryland, U.S.A.,

         4.7      Press Release and Other Permitted Disclosures Regarding the
                  First Amendment.

                  4.7.1    Press Releases. Each of Digene and MBL agree not to
                           announce this First Amendment by press release or
                           other form of communication without the written
                           approval of the other Party.

                  4.7.2    Permitted Disclosure. The Parties agree to keep the
                           terms of this First Amendment confidential with
                           exception of such information which in the opinion of
                           counsel to the disclosing party is required to be
                           disclosed by applicable law, rule, regulation or
                           generally accepted accounting practice, including any
                           rules of applicable stock exchanges and other
                           self-regulatory authorities or organizations on which
                           the Parties or their Affiliates are listed. Provided,
                           however, that in the event a Party or its

<PAGE>   7






                           Affiliates shall be required to disclose any of the
                           terms of this First Amendment, whether pursuant to
                           subpoena, deposition, interrogatory, or otherwise, or
                           a Party or its Affiliates shall otherwise propose to
                           disclose any of the terms of this First Amendment
                           (except in connection with such Party's or such
                           Affiliates' required disclosure under any applicable
                           securities laws, the rules of any applicable stock
                           exchange or other self regulatory authority or
                           organization or other reporting requirements) such
                           disclosing Party shall provide the other Party with
                           prompt written notice of such requirement so that the
                           other Party may seek a protective order or other
                           appropriate remedy and/or waive compliance with the
                           terms of this First Amendment. Notwithstanding the
                           foregoing, except as otherwise required by the
                           provisions of Section 4.7.1 hereof, (i) no prior
                           written notice shall be required in connection with
                           any Party's (or its Affiliates') required compliance
                           with applicable securities laws, the rules of any
                           applicable stock exchange or other self-regulatory
                           authority or organization or other reporting
                           requirements; and (ii) any Party shall be permitted
                           to submit this First Amendment as evidence in any
                           proceeding in connection with any dispute between the
                           Parties. The provisions of this Section 4.7.2 shall
                           not restrict a Party or its Affiliates from making
                           any disclosure of any terms of this First Amendment
                           to the extent such terms become generally available
                           to the public (other than as a result of a disclosure
                           by such Party in violation of this First Amendment),
                           or restrict the ability of the Parties and their
                           Affiliates from making disclosure to the extent such
                           disclosure is required for the effective undertaking
                           by the Parties of their respective rights and
                           obligations hereunder. By way of example and not in
                           limitation of the foregoing, MBL shall be entitled to
                           disclose to proposed customers the fact that it is
                           acting as an authorized distributor of the Products
                           or agent of Digene.

         4.8      Counterparts. This First Amendment shall be executed in
                  counterparts, each of which shall be deemed an original but
                  both of which together shall constitute the same instrument.

         4.9      All references to "Digene Diagnostics, Inc." under the
                  Distribution Agreement shall hereafter be changed to
                  references to "Digene Corporation".

         4.10     Conflict; Effectiveness of Distribution Agreement. In the
                  event of conflict between the provisions of this First
                  Amendment and the Distribution Agreement with respect to the
                  subject matter herein, this First Amendment shall control. All
                  other terms and provisions of the Distribution Agreement
                  remain in full force and effect.
