                        NOTES TO THE UNAUDITED CONDENSED
                       CONSOLIDATED FINANCIAL STATEMENTS


1. BASIS OF PREPARATION

     Diamond Cable Communications Plc (the "Company") owns and operates cable
television and telecommunications systems through its subsidiaries.  The
unaudited consolidated financial statements of the Company and its subsidiaries
(the "Group") have been prepared in accordance with U.S. generally accepted
accounting principles and the rules and regulations of the Securities and
Exchange Commission (the "SEC").  Accordingly, certain information and footnote
disclosures normally included in financial statements prepared in accordance
with generally accepted accounting principles have been condensed or omitted.
The financial statements are stated in pounds sterling (L.).  Merely for
convenience the financial statements contain translations of certain pound
sterling amounts into U.S. dollars at $1.6448 per L.1.00, the noon buying rate
in the City of New York for cable transfers in pounds sterling as certified for
customs purposes by the Federal Reserve Bank of New York on March 31, 1997.

2. RESPONSIBILITY FOR INTERIM FINANCIAL STATEMENTS

     The financial statements as of and for the periods ended March 31, 1997
and 1996 are unaudited.  However, in the opinion of the management, such
statements include all adjustments (consisting only of normal recurring
accruals) necessary for a fair presentation of the results for the periods
presented.  The results of operations for any interim period are not
necessarily indicative of the results for the full year.  The interim financial
statements should be read in conjunction with the financial information
included in the Company's 1996 Annual Report on Form 10-K filed with the SEC.

4. COMMITMENTS AND CONTINGENCIES

     The Company is obligated under the terms of its existing licenses, and
under the milestone requirements of its local delivery licenses ("LDLs"), to
construct cable systems passing a predetermined number of premises.  Should the
Company fail to achieve these milestones, without license modifications, the
Director General could commence proceedings to require compliance.  Similarly,
the Independent Television Commission ("ITC") may commence proceedings to
require compliance with the build milestones in the LDLs.  If the Company is
unable to comply, its licenses in respect of which milestones have not been met
could be revoked, which could have a material adverse effect on the Company.

5. 1997 SENIOR NOTES

     On February 21, 1997 the Company issued $420,500,000 of 10 3/4% Senior
Discount Notes due February 15, 2007 ("the 1997 Senior Notes") at an issue
price of $594.48 per $1.000 principal.  Total proceeds received by the Company
amounted to approximately L.149 million after issuance costs of approximately
L.5 million.  Interest on the 1997 Senior Notes will be payable on February 15
and August 15 of each year commencing August 15, 2002.

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

LIQUIDITY AND CAPITAL RESOURCES

     The Company expended net cash to fund investing activities of L.128.2
million and L.26.1 million in the year ended 1996 and the first three months of
1997, respectively.  Net cash provided by financing activities in the year
ended December 31, 1996 was L.54.4 million and net cash provided by financing
activities was L.148.6 million in the first three months of 1997.  The
Company's investing activities consisted almost exclusively of the ongoing
construction of the network (L.26.1 million in the first three months of 1997
and L.128.2 million in 1996).  In 1996 the Company's net cash used in operating
activities was L.1.3 million and in the three months to March 31, 1997 the
Company's net cash provided by operating activities was L.10.5 million.  The
Group's cash and funding requirements historically have been met principally
through the issuance of senior discount notes ("Senior Notes") in September
1994 and December 1995, equity capital, advances from its shareholders, and
from bank and lease financing.  In February 1997, the Company issued another
series of Senior Notes, raising net proceeds of approximately $240 million
(L.149 million).

     In August 1996, certain of the Company's subsidiaries entered into a
senior bank lending agreement that permitted borrowing up to an aggregate
amount of L.340 million. In February 1997, the senior bank facility was
amended, and the Company has subsequently negotiated further amendments to the
senior bank facility (as amended, the "Senior Bank Facility"), including a
reduction in the amount available for borrowing under the facility to L.175
million to reflect the additional proceeds available to the Company through the
February issue of Senior Notes.  DCL will be able to draw on the Senior Bank
Facility if certain conditions are met, including conditions related to the
operating cash flow of, equity contributions to and certain financial ratios of
Jewel and its subsidiaries (together, the "Borrower Group"). To date, no funds
have been drawn under the facility, and the Company does not anticipate
borrowing under the facility prior to meeting the necessary conditions.  The
facility does allow for the provision of guarantees and the Company has drawn a
bond of L.1.2 million in order to meet its obligations under the Group's
telecommunications licenses. Indebtedness under the Senior Bank Facility will
be incurred by DCL, guaranteed by the Borrower Group and secured by a lien on
the assets of the Borrower Group and a pledge of the issued shares of the
Borrower Group other than Jewel but including DCL and LCL.

     The further development and construction of the Group's cable television
and telecommunications network will require substantial capital investment. The
Group is obligated by the milestones in its telecommunications licenses and
LDLs to construct and activate a network passing an aggregate of 1,021,894
premises within prescribed time periods.

                                       11



<PAGE>   12
     Failure by the Group to meet its milestones could potentially subject the
Group to enforcement orders from OFTEL or the ITC, which could lead to
revocation of the relevant licenses or a shortening of an LDL period or fines.
In addition, under the Senior Bank Facility, failure to meet the Group's
milestone obligations could under certain circumstances prevent further
borrowing or result in an event of default.  The Group met the required
quarterly milestone obligations under each of its telecommunications licenses
as at March 31, 1997.

     The Company expects that the Group's residential cable network will extend
approximately 14,300 kilometers (plus 920 kilometers to interconnect the
residential build) and pass approximately 1.2 million homes once completed. The
network will be substantially completed by the end of 2001. The Company
currently estimates that the additional capital expenditures required for the
Group to substantially complete the network (including estimated subscriber
connection expenses) will be approximately L.550 million (of which L.500
million relates to capital expenditures occurring from March 31, 1997 through
January 1, 2001), although these amounts could vary significantly.

     The Company believes that available cash reserves and cash flows from
operations will be sufficient to complete the planned construction through the
first quarter of 1998, at which time the Group estimates that approximately
61.4% of the aggregate final milestones will have been constructed and
activated. Thereafter, the Company expects that the Group will be able to
utilize amounts under the Senior Bank Facility.  If such amounts are not
available or are insufficient, the Group would be required to obtain further
debt and/or equity financing.

     DCL will be able to draw on the Senior Bank Facility if it is able in the
future to meet certain conditions, including conditions related to the
operating cash flow of, equity contributions to and certain financial ratios of
the Borrower Group which are not currently met.  However, the Group may not be
able to borrow sufficient funds under the Senior Bank Facility to meet its
remaining funding requirements. In particular, even after the initial
conditions to borrowing have been met the amount of funds that may be borrowed
will be limited to a specified multiple of the Borrower Group's reported
annualized cash flow (as defined in the Senior Bank Facility). This reported
annualized cash flow will depend on a number of variables,including revenue
market share of business telecommunications and penetration of residential
telephone, cable television and premium channels, average revenues in each of
these areas, churn, expenses such as programming costs and interconnect
charges, network construction and development expenditures and financing costs.
Adverse developments in any of these or other areas could adversely affect the
Borrower Group's reported annualized cash flow and reduce amounts available
under the Senior Bank Facility.

     To the extent that (i) the Group is unable to utilize fully the Senior
Bank Facility, (ii) the amounts required to complete the Group's

                                       12
<PAGE>   13
planned build out exceed its estimates or (iii) the Borrower Group's
reported annualized cash flow (as defined in the Senior Bank Facility) does not
meet expectations, the Group will require additional debt and/or other
financing. There can be no assurance that any such debt financing will be
permitted under the terms of the Group's debt instruments, which limit the
incurrence of additional debt by the Group, or that any such debt or other
financing will be available on acceptable commercial terms or at all.

     The foregoing information with regard to expected completion times, future
capital expenditures and the sufficiency of funding is forward-looking in
nature. Due to factors identified in the preceding two paragraphs and below,
actual results may differ materially from the expected results. There can be no
assurance that (i) conditions precedent to advances or the availability of
funds under any of the Group's existing and anticipated debt instruments will
be satisfied when funds are required; (ii) the Group will be able to generate
sufficient cash from operations to meet any unfunded portion of its capital
requirements when required; (iii) the cost of constructing and activating the
network will not increase significantly; (iv) the Group will not acquire
additional franchise areas, which would require additional capital
expenditures; or (v) the Group will not incur losses from foreign currency
transactions or its exposure to foreign currency exchange rate fluctuations.

     The inability of the Group to secure additional financing could result in
a failure to comply with the minimum build milestones set forth in its licenses
and could ultimately lead to the revocation of such licenses.

     The Group's revenues are denominated in pounds sterling, while its
obligations to pay interest and principal on the three series of Senior Notes
are denominated in U.S. dollars. Therefore, the Company and the Group are
subject to currency exchange risks that may adversely affect their ability to
meet their obligations, including obligations under outstanding debt
instruments, as they become due.

SELECTED OPERATING DATA

     The following table sets forth certain data concerning the Group's
franchises at and for the years ended December 31, 1995 and 1996 and at and for
the three-month period ended March 31, 1997.  The combined operating data at
and for the year ended December 31, 1995 reflects the acquisition of LCL on a
pro-forma basis as if it had been completed at the beginning of 1995.

</TABLE>

(1)  Homes passed by civils is the number of homes that have had ducting buried
     outside. 

(2)  Homes activated is the number of homes that are capable of receiving cable
     service without further extension of transmission lines, apart from the
     final connection to the home. 

(3)  Homes marketed is the number of homes activated for which the initial
     marketing phase has been completed. 

(4)  Penetration rate of homes marketed is calculated by dividing the number of
     homes receiving basic cable television or the number of residential lines
     connected, as the case may be, on the given date by the total number of
     homes marketed for the given service as of such date, expressed as a
     percentage. 

(5)  The average monthly revenue per cable television subscriber is calculated
     by dividing total cable television subscriber revenues (excluding
     installation revenues) for the period by the average number of cable
     television subscribers (calculated as a simple average of the number of
     basic service subscribers at the end of each month during the period) and
     dividing that amount by 12 (for the years ended December 31, 1995 and 1996)
     or by three (for the three months ended March 31, 1997).

(6)  Churn is calculated by dividing net disconnections (total disconnections
     less the number of disconnected accounts for which service is later
     restored) in a period by the average number of subscribers in the period
     (calculated as a simple average of the number of subscribers at the end of
     each month during the period).  Churn for the three months ended March 31,
     1997 is annualized by multiplying the amount as calculated above by four.

(7)  The Company changed the method of calculating churn for the quarter ended
     March 31, 1997 to eliminate from the number of net disconnected accounts
     those subscribers who disconnect from the service when moving residence and
     reconnect to the service in their new residence.  These subscribers could
     not be identified under the Company's information systems prior to the
     first quarter of 1997 and were therefore included in the churn calculation
     as disconnected accounts.  If churn for the quarter to March 31, 1997 were
     calculated on a basis consistent with prior periods churn would have been
     (annualized) 49.7% and 21.9% for cable television and residential
     telephone, respectively.  The difference between churn on the new and prior
     bases is not necessarily indicative of the adjustment that would arise if
     it were possible to recalculate the churn for prior quarters.

(8)  The average monthly revenue per residential telephone line is calculated by
     dividing (i) line and equipment rental, outgoing call charges and incoming
     call charges for the period by (ii) the average number of residential
     telephone lines (calculated as a simple average of the number of subscribed
     lines at the end of each month during the period) and dividing that amount
     by 12 (for the years ended December 31, 1995 and 1996) or by three (for the
     three months ended March 31, 1997).

(9)  The calculation of the average monthly revenue per line (for both
     residential telephone and business telecommunication revenues) for the year
     to December 31, 1996 reflects the reduction in revenues stemming from
     rebates to BT on incoming termination revenues relating in part to 1995 but
     recorded in full against revenues in 1996.  The rebates were calculated in
     accordance with recently revised interconnect agreements with BT that were
     made effective retroactively from April 1995.  The pro-forma average
     monthly revenue per line (for both residential telephone and business
     telecommunications revenues) gives effect to the revised interconnect
     agreements as if they had been in effect from April 1995 and allocates to
     each period the portion of the rebates that relates to such period.

                                       14

(10) Private circuits are point-to-point customer specific connections for which
     a fixed annual rental charge is made.

(11) Average lines per business account is calculated by dividing the number of
     business lines connected on the given date by the number of business
     customer accounts on such date.

(12) The average monthly business telecommunications revenue per line is
     calculated by dividing (i) business telecommunications line and equipment
     rental, outgoing call charges and incoming call charges (including revenue
     from private circuits) for the period by (ii) the average number of
     business telecommunications lines and private circuits (calculated as a
     simple average of the number of subscribed lines and private circuits at
     the end of each month during the period) and dividing that amount by 12
     (for the years ended December 31, 1995 and 1996) or by three  (for the
     three months ended March 31, 1997).

RESULTS OF OPERATIONS FOR THE THREE-MONTH PERIODS ENDED MARCH 31, 1996 AND 1997

     The Group continued to experience increases in its subscribers, revenues
and expenses during the three month period ended March 31, 1997.  In general,
these increases were attributable to the Group's continued network
construction, activation and marketing of new homes and businesses.  Homes
passed by civils construction increased by 20,245 homes (4.5%) and homes
activated increased by 19,267 (5.5%) from December 31, 1996 to March 31, 1997.
During the three months to March 31, 1997 the Company's pace of civils
construction and activation slowed due in large part to the phase out during
the period of one of the Company's largest contractors which went into
liquidation.  Nevertheless, the Group met the required quarterly milestone
obligations under each of its telecommunications licenses as at March 31, 1997.

     In addition, in order to improve the management and quality of the
residential sales force, in February 1997 the Company terminated arrangements
with its independent sales contractors and began to develop its own internal
sales force through direct hiring of residential sales people.  Prior to this
reorganization, the sales force comprised approximately 150 residential sales
people who were employed by the independent contractors that the Group paid on
a full commission basis.  The Group now employs residential sales people
directly and pays them on the basis of a salary plus sales commission.  At
March 31, 1997, the Company employed approximately 120 residential sales
people, including former contracted sales people who were hired by the Company
in accordance with its employment criteria following interviews.  The Company
is planning to increase the number of residential sales people further.  The
reorganization has delayed the progress of marketing and affected penetration
in the areas being marketed during this transitional period.  At March 31,
1997, residential telephone line penetration had fallen to 39.8% and cable
television penetration had fallen to 21.4% from 41.4% and 23.5% respectively at
December 31, 1996.  Penetration rates for residential telephone and cable
television were 41.9% and 23.9% at March 31, 1996.

     REVENUE

                                       15
<PAGE>   16

     For the three months ended March 31, 1997, total revenues were L.13.2
million, a 67% increase over total revenues of L.7.9 million for the comparable
period in 1996.  This growth is attributable to increases in revenues in all
three of Diamond's primary lines of business.

     As a result of entering into revised interconnect agreements with BT which
will apply retroactively, the Company will receive outgoing interconnect charge
rebates relating to all periods prior to December 31, 1996 and must pay
incoming termination rebates relating to the period from April 1, 1995 to
December 31, 1996.  Based on interim rates for the year to March 31, 1997, no
rebates will be payable to or due from BT for the three month period to March
31, 1997.  The rebates that will be paid to BT relating to the incoming
termination element amount to an estimated L.1,351,000 based on draft final
rates for the twelve month period from April 1, 1995 and interim rates for the
nine month period from April 1, 1996.  This amount has been provided by
reducing residential telephone and business telecommunications revenues in 1996
by L.776,000 and L.575,000, respectively, of which L.151,000 and L.122,000,
respectively, relates to the three month period ended March 31, 1996.  The
total amount of rebates to be received by the Company will be determined by the
parties once BT has furnished to the Company a proposed calculation and
supporting data and OFTEL has determined the final rates applicable.  The
Company has estimated that the amount of the rebate due to the Company from BT
will exceed the amount of the rebates to be provided by the Company to BT.
Pending final determination of rebates, the Company has recognized a reduction
in interconnect charges in the same period during which the related reduction
in revenues is being recognized.  Accordingly, a reduction in telephone
expenses of L.1,351,000 has been recorded in 1996 of which L.273,000 relates to
the three month period ended March 31, 1996.

     The analysis of revenue and average revenue per line is provided below on
the basis of revenues as reported as well as on a pro-forma basis for periods
up to December 31, 1996 adjusting for the incoming termination rebates in the
appropriate periods as if the revised interconnect agreements and the draft
final rates for the year to March 31, 1996 and interim rates for the nine
months to December 31, 1996 had been in effect.

     Business Telecommunications.  Business telecommunications revenue was
L.3.2 million for the three month period ended March 31, 1997 compared to L.2.4
million (pro-forma L.2.2 million) for the comparable period in 1996,
representing an increase of 34% (41% on a pro-forma basis).  The growth in
reported revenues is due primarily to an increase in the number of business
lines installed from 11,054 at March 31, 1996 to 20,874 at March 31, 1997, an
increase of 89%.  The growth in the number of business lines was partially
offset by lower monthly revenue per line.  The monthly revenue per line
decreased from L.70.70 in the three months to March 31, 1996 (L.66.90 on a pro-

                                       16

<PAGE>   17

forma basis) to L.47.14 in the comparable period in 1997.  This decline was due
to a combination of (i) Diamond's success in marketing Centrex services which
has the effect of increasing the average number of lines held by existing and
new customers taking those services (the Company operated 8,522 Centrex lines
at March 31, 1997 compared to 2,832 Centrex lines at March 31, 1996), (ii) a
reduction in certain tariffs in response to price reductions by competitors,
including BT, Diamond's principal competitor for business telecommunications
services which reduced in June 1996 its prices by an average of 10% for most of
its business customers and made smaller price reductions at other times during
1996, and (iii) the installation for existing customers of an increasing number
of lines utilized for incoming calls in addition to existing lines dedicated
solely to outgoing calls.  Monthly revenue per line has remained relatively
stable during the three month periods ended September 30, 1996, December 31,
1996 and March 31, 1997.  The Company may lower prices in the future if
necessary for competitive reasons.

     Residential Telephone.  Residential telephone revenues were L.6.2 million
in the three month period to March 31, 1997 compared to L.3.6 million (L.3.4
million on a pro-forma basis) for the comparable period in 1996, an increase of
74% (79% on a pro-forma basis).  The growth in residential telephone revenue is
due primarily to an increase in the number of residential telephone lines from
64,095 at March 31, 1996 to 111,881 at March 31, 1997, representing an increase
of 75%. Monthly revenue per line was L.19.88 (pro-forma L.19.24) in the three
month period to March 31, 1996 and L.18.62 in the comparable period in 1997.
The fall in average revenues was partly due to a reduction in overall tariffs
for LCL subscribers in July 1996 to conform tariffs for all Diamond subscribers
together with additional call tariff reductions in late 1996.  These call
tariff reductions were partly offset by increases in line rental charges in
January 1997.  The Company will continue to review and adjust its tariffs to
maintain its price competitive advantage.  The churn rate (annualized) was
18.1% for the first three months of 1997 (21.9% before taking into account the
new adjustments described above in Note 7 to the Selected Operating Data) as
compared to 16.0% in the comparable period in 1996.  The increase in churn in
1997 is attributable in part to a tighter disconnect policy for certain
customers and ongoing efforts by BT aimed at regaining former customers.

     Cable Television.  Cable television revenues increased from L.2.0 million
in the three months to March 31, 1996 to L.3.8 million in the comparable period
in 1997, an increase of 95%.  This growth in cable television revenue was
primarily due to a combination of an increase in the number of cable television
subscribers which rose from 36,574 at March 31, 1996 to 60,008 at March 31,
1997, an increase of 64% and an increase in the average monthly revenue per
subscriber from L.18.23 for the first three months of 1996 to L.20.35 for the
comparable period in 1997.  The

                                       17
<PAGE>   18
increase in average revenue per subscriber is primarily due to increases in
cable television pricing.  The number of cable television subscribers increased
by 766 from 59,242 at December 31, 1996 to 60,008 at March 31, 1997.  This was
supplemented by an increase in average revenues from L.18.94 in the quarter to
December 31, 1996 to L.20.35 in the quarter to March 31, 1997, resulting in an
increase in cable television revenues of 15% between the quarter to December
31, 1996 and the first quarter of 1997.  The small increase in the number of
subscribers was due to the delay in the sales effort described earlier and the
level of churn.

     The Group's churn rate was 46.8% for the three months to March 31, 1997
(49.7% before taking into account the new adjustments described above in Note 7
to the Selected Operating Data) as compared to a churn rate of 36.6% in the
comparable period in 1996.  The Company believes that the increase in churn was
due in part to the continuing effect of increases in the fourth quarter of 1996
in premium subscription rates which led certain longer-term customers who had
previously benefitted from grandfathered rates, to disconnect service, the
effect of an increase in the basic subscription rate, additional price
increases resulting from the Company passing on to its customers a new BskyB
charge for Sky Sports 3 (which BSkyB provides to its own sports subscribers at
no additional charge) and other aggressive promotional activity of BSkyB, as
well as to the application of a stricter disconnect policy relating to non
payment.  With the aim of reducing churn among new subscribers, the Company has
begun to require payment of an installation fee in connection with the
subscription for new residential services and is evaluating other means to
reduce its churn in the future.

     OPERATING COSTS AND EXPENSES

     Telephone expenses, consisting principally of interconnect charges payable
to BT, Mercury and Energis were L.2.7 million in the three months to March 31,
1996 and L.2.6 million in the three months to March 31, 1997.  On a pro-forma
basis reflecting the apportioned reduction in interconnect charges resulting
from the revised interconnect agreements in the appropriate periods to which
they relate, telephone expenses would have been L.2.4 million in the three
months to March 31, 1996.  As a percentage of combined business
telecommunications and residential telephone revenues, these direct costs
decreased from 45% (42% on a pro-forma basis) in the three months to March 31,
1996 to 28% in the comparable period in 1997 due primarily to reduced
interconnect charges paid to these operators.

     Direct costs for cable television programming, which generally depend on
the number of subscribers and per-subscriber rates charged by programming
suppliers, increased from L.1.2 million in the three months to March 31, 1996
to L.2.3 million in the comparable period in 1997.  As a percentage of cable

                                       18
<PAGE>   19

television revenues, these direct costs were 60% in both the three month
periods ended March 31, 1996 and 1997.

     Selling, general and administrative expenses increased by 27% from the
three months to March 31, 1996 to the comparable period in 1997.  The increase
was due to higher administration costs associated with the expansion of the
Company's business.  In February 1997, the Group began employing residential
sales people directly and paying them on the basis of a salary plus sales
commissions.

     Depreciation and amortization expenses increased by 38% from the three
month period to March 31, 1996 to the comparable period in 1997.  This increase
was attributable to the increasing size of the Company's network.

     INTEREST INCOME/EXPENSE

     Interest expense was L.12.2 million in the three months ended March 31,
1997 compared to L.10.0 million in the comparable period in 1996.  The increase
is due primarily to the accretion on the Senior Notes of L.11.2 million in the
first quarter of 1997 (compared to L.9.5 million in the first quarter of 1996).
In addition, amortization of debt financing costs was L.0.5 million and other
interest expense was L.0.5 million in the three months to March 31, 1997,
compared to L.0.2 million and L.0.3 million respectively in the three months to
March 31, 1996.  Interest received was L.0.9 million in the three months to
March 31, 1997 through temporary investments of the proceeds of the 1997 Senior
Notes.

     FOREIGN EXCHANGE

     A substantial portion of the Group's existing debt obligations are
denominated in U.S. dollars, while the Group's revenues and accounts are
generated and stated in pounds sterling. Foreign currency translation gains and
losses, except for unrealized gains and losses on available-for-sale
securities, are reported as part of the profit or loss of the Group. In the
year ended December 31, 1996, the Group recognized an unrealized foreign
exchange gain on the translation of its liability on the Senior Notes issued in
1994 and 1995 of L.31.5 million, an unrealized gain on its short-term
securities of L.0.1 million and a net realized foreign exchange loss of L.0.4
million relating to its operations. During the three months ended March 31,
1997, the Group recorded a net foreign exchange loss of L.12.0 million
primarily due to the unrealized loss on translation of its liability on the
Senior Notes.

     GAINS ON DERIVATIVE FINANCIAL INSTRUMENTS

     Unrealized gains on derivative financial instruments of L.0.1 million in
the three months to March 31, 1997 consist of the

                                       19
<PAGE>   20

mark-to-market valuation of an interest rate swap commitment.

     The Company entered into a foreign exchange forward contract on November
1, 1996 for settlement on May 6, 1997 to sell L.200 million at a rate of
$1.6289 to L.1. On January 31, 1997 an offsetting agreement was entered into at
a rate of $1.6014 to L.1. The offsetting contracts were settled on February 6,
1997 with a payment of approximately L.3.4 million to the Company. Because of
changes in prevailing rates, the Company recorded for the year ended December
31, 1996, an unrealized loss of approximately L.8.1 million on the pounds
sterling sell forward contract which partially offset the gain that was
recorded on the translation of the U.S. dollar denominated obligations on the
1994 Senior Notes and 1995 Senior Notes during the same period. During the
first quarter of 1997, the Company has recorded a gain of approximately L.11.5
million on the two offsetting forward contracts, reflecting the reversal of an
L.8.1 million loss referred to above and the approximately L.3.4 million cash
payment on settlement of the contracts. The realized gain on the foreign
exchange forward contract in the first quarter of 1997 largely offset the
unrealized loss that was recorded in the same period on the translation of the
U.S. dollar denominated obligations on the Senior Notes.  The Company may from
time to time in the future enter into similar foreign currency contracts based
on its assessment of foreign currency market conditions and their effect on the
Group's operations and financial condition.  Therefore, changes in currency
exchange rates may continue to have a material effect on the results of
operations of the Group and may materially affect the Company and the Group's
ability to satisfy their obligations, including obligations under outstanding
debt instruments, as they become due.

     NET LOSS

     As a result of the foregoing factors, Diamond had net losses of L.15.9
million in the three-month period ended March 31, 1997, compared to net losses
of L.19.0 million in the comparable period of 1996.
