EDGE PETROLEUM CORPORATION
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      The  financial  statements  included  herein  have been  prepared  by Edge
Petroleum  Corporation,  a Delaware  corporation (the "Company"),  without audit
pursuant to the rules and regulations of the Securities and Exchange Commission,
and reflect all adjustments  which are, in the opinion of management,  necessary
to present a fair  statement  of the results for the interim  periods on a basis
consistent with the annual audited consolidated  financial statements.  All such
adjustments are of a normal recurring nature.  The results of operations for the
interim periods are not necessarily indicative of the results to be expected for
an  entire  year.  Certain   information,   accounting   policies  and  footnote
disclosures  normally  included in financial  statements  prepared in accordance
with generally accepted accounting principles have been omitted pursuant to such
rules and  regulations,  although the Company  believes that the disclosures are
adequate to make the information  presented not  misleading.  Certain prior year
amounts have been reclassified to conform to the current year presentation. Such
reclassifications  do not affect net income (loss).  These financial  statements
should be read in conjunction with the Company's audited consolidated  financial
statements  included in the  Company's  Annual  Report on Form 10-K for the year
ended December 31, 1998.

         Accounting Change - The Company uses the full-cost method of accounting
for its oil and natural gas  properties.  Under this  method,  all  acquisition,
exploration  and  development  costs  that  are  directly  attributable  to  the
Company's acquisition, exploration and development activities are capitalized in
a "full-cost  pool" as  incurred.  In the second  quarter of 1998 and  effective
January 1, 1998,  the Company  changed  its method of  accounting  for  internal
geological and geophysical ("G&G") costs to one of capitalization of such costs,
which are directly  attributable  to  acquisition,  exploration  and development
activities,  to oil and natural gas properties.  Prior to the change the Company
expensed these costs as incurred.  The Company  believes the  accounting  change
provides  for a better  matching of  revenues  and  expenses  and  enhances  the
comparability  of it's financial  statements  with those of other companies that
follow the full-cost method of accounting.  Accordingly,  the financial  results
for the period  ended  March 31,  1998 have been  restated to give effect to the
change in accounting method effective January 1, 1998. The $1,780,835 cumulative
effect  of the  change in prior  years  (after  reduction  for  income  taxes of
$958,910) is included in income for the three  months ended March 31, 1998.  The
effect of the accounting  change on the three months ended March 31, 1998 was to
increase net income by $2,041,066 or $0.26 basic and diluted  earnings per share
($260,231  before  cumulative  effect of  accounting  change or $0.03  basic and
diluted earnings per share).

Accounting Pronouncements

Derivatives - In June 1998,  the  Financial  Accounting  Standards  Board issued
Statement of Financial  Accounting Standard No. 133,  "Accounting for Derivative
Instruments and Hedging Activity" ("SFAS 133"). SFAS 133 establishes  accounting
and reporting  standards for derivative  instruments and hedging activities that
require an entity to recognize all derivatives as an asset or liability measured
at fair value. Depending on the intended use of the derivatives,  changes in its
fair value will be  reported  in the period of change as either a  component  of
earnings or a component of other comprehensive income.

SFAS 133 is effective  for all fiscal  quarters  beginning  after June 15, 1999.
Earlier application of SFAS 133 is encouraged, but not prior to the beginning of
any fiscal  quarter that begins  after  issuance of the  statement.  Retroactive
application  to periods  prior to adoption is not  allowed.  The Company has not
quantified  the impact of adoption on its  financial  statements  or the date it
intends to adopt.

2.   LONG TERM DEBT

         During July 1995, the Company entered into a revolving  credit facility
(the  "Revolving  Credit  Facility")  with a bank to finance  temporary  working
capital  requirements.  The Revolving Credit Facility provided up to $20 million
in borrowings  limited by a borrowing  base, as defined by the Revolving  Credit
Facility.  The Revolving  Credit Facility  provided for interest at the lender's
prime rate plus 0.75%. The borrowing base was subject to review by the bank on a
quarterly basis and could be adjusted subject to the provisions of the Revolving
Credit  Facility.  Effective April 1, 1998, the Company amended and restated its
Revolving  Credit  Facility to provide a revolving  line of credit of up to $100
million  bearing  interest  at a rate  equal to prime  or LIBOR  plus  1.5% - 2%
depending on the level of borrowing  base  utilization.  The  Company's  initial
borrowing  base  authorized  by the banks was  approximately  $15  million.  The
Revolving  Credit  Facility  is secured by  substantially  all the assets of the
Company.

      Effective   September  29,  1998,  the  Company  had  its  borrowing  base
redetermined and amended its Revolving Credit  Facility.  The initial  borrowing
base authorized by the bank was $15 million.  Beginning  October 1, 1998, and on
the first day of each month  thereafter,  the borrowing  base was required to be
reduced by $550,000.

      The Revolving Credit Facility provides for certain restrictions, including
but not limited to,  limitations on additional  borrowings and issues of capital
stock, sales of its oil and natural gas properties or other collateral, engaging
in merger or  consolidation  transactions  and  prohibitions  of  dividends  and
certain  distributions  of cash or properties and certain  liens.  The Revolving
Credit Facility also contains certain financial covenants.

     Effective  March 1, 1999, the Company and the Bank amended the Revolving
Credit  Facility to include the following  terms; 1),the initial borrowing base
 is $12 million comprised of a two tranche financing of a $9 million Revolving
Credit Facility and a $3 million term  facility,  2) Beginning May 1, 1999,
and on the first day of each month  thereafter,  the Revolving  Credit  Facility
borrowing  base is required to be reduced by $400,000,  3) 75% of prospect sales
will be used to pay down the term facility with the remaining  unpaid term
facility  balance  maturing on August 31, 1999.  The Company and the Bank also
amended the  Revolving  CreditFacility to replace the financial covenants on a
go forward basis with a Tangible Net Worth Covenant and Fixed Charge Covenant.
TheTangible Net Worth  Covenant  requires that at the end of each quarter the
Company's  Tangible Net Worth be at least 90% of the Company's  actual tangible
networth as reported at December 31, 1998 (or  $33,260,720)  plus 50% of
positive net income and 100% of other  increases in equity for all fiscal
quarters  ending  subsequent to December 31, 1998.  The Fixed Charge  Covenant
requires that at the end of each quarterbeginning  June 30, 1999,  the ratio of
annualized  EBITDA (as defined) to the sum of annualized  interest  expense plus
50% of the quarter end loans  outstanding  must be at least 1.25 to 1.00.
Interest will accrue at a rate of LIBOR plus 1.75% - 2.75% depending on the
borrowing base utilization.

3.   EARNINGS PER SHARE

The Company  accounts  for earnings per share in  accordance  with  Statement of
Financial  Accounting  Standard No. 128 - "Earnings per Share," ("SFAS No. 128")
which  establishes the requirements  for presenting  earnings per share ("EPS").
SFAS No. 128 requires the  presentation of "basic" and "diluted" EPS on the face
of the income statement.  Basic earnings per common share amounts are calculated
using the  average  number of common  shares  outstanding  during  each  period.
Diluted  earnings  per share  assumes the exercise of all stock  options  having
exercise prices less than the average market price of the common stock using the
treasury stock method.

              The following is presented as a  reconciliation  of the numerators
      and denominators of basic and diluted earnings per share computations,  in
      accordance with SFAS No. 128.

4.   SUBSEQUENT EVENT

         On May 6, 1999, the Company  completed a private  offering of 1,400,000
shares of common stock based on a market price of $5.3125 per common share.  The
private offering also provides for warrants, which were purchased for $0.125 per
share,  to acquire an  additional  420,000  shares of common  stock at $5.35 per
share. Total proceeds, net of offering costs, were approximately $7.4 million of
which $4.9 million was used to repay debt under the  Revolving  Credit  Facility
with the remainder to be used to satisfy working capital requirements and fund a
portion of the Company's future exploration program. After the repayment of debt
the Company has available  approximately $1.5 million under its Revolving Credit
Facility for future borrowings.

5.   INCOME TAXES

The Company  accounts  for income  taxes under the  provisions  of  Statement of
Financial  Accounting  Standards No. 109 - "Accounting for Income Taxes," ("SFAS
No. 109") which provides for an asset and liability  approach for accounting for
income  taxes.  Under this  approach,  deferred tax assets and  liabilities  are
recognized based on anticipated future tax consequences, using currently enacted
tax laws,  attributable  to differences  between  financial  statement  carrying
amounts of assets and  liabilities  and their  respective tax bases.  Due to the
Company  incurring a net loss for the three  months ended March 31, 1999 and due
to the Company having significant  deferred tax assets, no tax benefit (expense)
was  recorded.  Due to  the  uncertainty  of the  Company's  ability  to  become
profitable  in the  future an  allowance  has been  provided  to offset  the tax
benefits  of certain tax  assets.  Should the Company  have net income in future
periods  income tax expense will be recorded  upon  utilization  of deferred tax
assets.

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

      The  following  is   management's   discussion  and  analysis  of  certain
significant  factors  that  have  affected  certain  aspects  of  the  Company's
financial  position and  operating  results  during the periods  included in the
accompanying  unaudited  condensed   consolidated  financial  statements.   This
discussion  should  be read  in  conjunction  with  the  accompanying  unaudited
condensed consolidated financial statements included elsewhere in this Form 10-Q
and with the Company's audited consolidated financial statements included in the
Company's  annual  report on Form 10-K for the year  ended  December  31,  1998.
Unless otherwise  indicated by the context,  references  herein to the "Company"
mean Edge Petroleum Corporation,  a Delaware corporation that is the registrant,
and its corporate subsidiaries .

Overview

         Edge Petroleum  Corporation is an independent energy company engaged in
the  exploration,  development  and  production  of oil and  natural  gas.  Edge
conducts its operations  primarily along the onshore Gulf Coast with its primary
emphasis  in  South  Texas  and  South  Louisiana  where it  currently  controls
interests in excess of 222,000  gross acres under lease and option.  The Company
explores for oil and natural gas by  emphasizing  an integrated  application  of
highly advanced data visualization  techniques and computerized 3-D seismic data
analysis to identify potential hydrocarbon  accumulations.  The Company believes
its approach to processing and analyzing geophysical data differentiates it from
other  independent  exploration  and production  companies and is more effective
than  conventional  3-D seismic data  interpretation  methods.  The Company also
believes it maintains  one of the largest  databases of onshore South Texas Gulf
Coast 3-D seismic data of any  independent  oil and natural gas company,  and is
continuously acquiring additional data within this core region.

         The Company  acquires  3-D seismic  data by  organizing  and  designing
regional data  acquisition  surveys for its proprietary  use, as well as through
selective  participation in regional  non-proprietary  3-D surveys.  The Company
negotiates  seismic  options  for a  majority  of the areas  encompassed  by its
proprietary surveys, thereby allowing it to secure identified prospect leasehold
interests  on  a   non-competitive,   pre-arranged   basis.   In  the  Company's
non-proprietary 3-D survey areas, the Company's technical  capabilities allow it
to rapidly and  comprehensively  evaluate  large volumes of regional 3-D seismic
data,  facilitating  its  ability  to  identify  attractive  prospects  within a
surveyed  region and to secure the  corresponding  leasehold  interests ahead of
other industry participants.

         The  Company's   extensive   technical  expertise  has  enabled  it  to
internally  generate  substantially all of its 3-D prospects drilled to date and
to assemble a large  portfolio of 3-D based prospects for future  drilling.  The
Company  pursues  drilling  opportunities  that  include  a blend of  shallower,
normally pressured reservoirs that generally involve moderate costs and risks as
well as deeper,  over-pressured  reservoirs that generally involve greater costs
and risks, but have higher economic potential. During the past year, the Company
has  expanded  its  relative  focus to  increase  its  exposure  to  exploration
opportunities  in the deeper  geological  section.  The  Company  mitigates  its
exposure  to  exploration  costs  and risk by  conducting  its  operations  with
industry partners,  including major oil companies and large  independents,  that
generally pay a disproportionately  greater share of seismic acquisition and, in
many  instances,  leasing and drilling  costs than the Company.  The Company may
seek to participate in an increased  number of externally  generated  prospects,
including those in which the Company pays a disproportionate  share of the cost,
depending  upon the  quality,  size,  price and other  factors  relating to such
prospects.

         The Company uses the  full-cost  method of  accounting  for its oil and
natural gas  properties.  Under this method,  all  acquisition,  exploration and
development costs,  including certain general and administrative  costs that are

                                       10
<PAGE>

directly attributable to the Company's acquisition,  exploration and development
activities,  are  capitalized  in a "full-cost  pool" as  incurred.  The Company
capitalizes  internal Geological and Geophysical ("G&G") costs that are directly
attributable to acquisition,  exploration and development  activities to oil and
natural gas properties.  Total internal G&G costs  capitalized  during the three
months ended March 31, 1999 and 1998 were $563,592 and  $539,965,  respectively.
The Company records depletion of its full-cost pool using the unit of production
method. Investments in unproved properties are not subject to amortization until
the proved  reserves  associated  with the projects can be  determined  or until
impaired.  To the extent that  capitalized  costs subject to amortization in the
full-cost  pool (net of depletion,  depreciation  and  amortization  and related
deferred  taxes)  exceed  the  present  value  (using  a 10%  discount  rate) of
estimated  future  net  after-tax  cash flows from  proved oil and  natural  gas
reserves,  such  excess  costs are  charged to  operations.  Once  incurred,  an
impairment of oil and natural gas  properties is not reversible at a later date.
Impairment of oil and natural gas properties is assessed on a quarterly basis in
conjunction with the Company's  quarterly filings with the Commission.  At March
31, 1999, no full cost ceiling test write down of oil and natural gas properties
was necessary.

      Due to the  instability  of oil and natural  gas  prices,  the Company has
entered into, from time to time, price risk management transactions (e.g., swaps
and  collars)  for a portion of its  natural  gas  production  to achieve a more
predictable  cash flow, as well as to reduce  exposure from price  fluctuations.
While  the use of these  arrangements  limits  the  benefit  to the  Company  of
increases  in the price of  natural  gas it also  limits  the  downside  risk of
adverse price  movements.  The Company's  hedging  arrangements  apply to only a
portion of its  production  and provide only partial  price  protection  against
declines in natural gas prices and limits  potential gains from future increases
in prices.  The Company  accounts for these  transactions as hedging  activities
and, accordingly,  gains and losses are included in oil and natural gas revenues
during the period the hedged  transactions  occur.  During  December  1998,  the
Company  entered  into a fixed price swap for $1.96 per MMbtu  (delivered  price
basis, Houston Ship Channel),  with settlement for each calendar month occurring
five business days following the publishing of the Inside F.E.R.C. Gas Marketing
Report.  This fixed  price swap  covers  13,000  MMbtu per day and is  effective
beginning  March 1, 1999 and  expires on October  31,  1999.  Total  natural gas
production  hedged under this arrangement was 403,000 MMbtu for the three months
ended March 31, 1999 or 21% of the current quarter's production.  Existing swaps
currently  cover  approximately  68% of current daily  production.  During April
1999,  the Company  entered  into a fixed  price swap for $2.15 per MMbtu.  This
fixed price swap covers  3,000 MMbtu per day and is effective  beginning  May 1,
1999 and expires on October 31,  1999.  During the three  months ended March 31,
1998,  the  Company  had in place  two  natural  gas  commodity  collars  with a
financial  institution  one of which  expired on January 31, 1998 with the other
expiring on April 30, 1998.  These  collars each covered 5,000 MMbtu per day, or
approximately  29% of the Company's  daily  production,  with floating floor and
ceiling  prices ranging  between $2.25 MMbtu and $3.15 per MMbtu.  Total natural
gas production hedged under these collars was 450,000 MMbtu for the three months
ended March 31, 1998 or 29% of production.  Included within natural gas revenues
for the three  month  periods  ended March 31,  1999 and 1998 was  $142,346  and
$36,700, respectively, representing net gains from swap and collar activities.

         The  Company's  revenue,  profitability  and future  rate of growth and
ability to borrow funds or obtain additional capital,  and the carrying value of
its properties,  are substantially  dependent upon prevailing prices for oil and
natural  gas.  These  prices are  dependent  upon  numerous  factors  beyond the
Company's control, such as economic,  political and regulatory  developments and
competition from other sources of energy. Oil prices have declined significantly
during the past year and more  recently  natural gas prices  have shown  similar
declines. Even though prices have shown signs of resent recovery since March 31,
1999, a substantial or extended decline in oil and natural gas prices could have
a material  adverse  effect on the  Company's  financial  condition,  results of
operation  and access to capital,  as well as the  quantities of oil and natural
gas reserves that the Company may economically produce.

RESULTS OF OPERATIONS

Three Months Ended March 31, 1999 Compared to the Three Months Ended
March 31,1998

Revenue and Production

      Oil and natural gas  revenues  for the three  months  ended March 31, 1999
decreased 6% from $3.8 million to $3.5 million,  as compared to the three months
ended March 31, 1998.  Production  volumes for oil and  condensate for the three
months ended March 31, 1999 decreased 11% from 42 MBbls to 37 MBbls, as compared
to the three  months ended March 31,  1998.  The decrease in oil and  condensate
production  during the three months ended March 31, 1999  decreased  revenues by
$64,580 (based on 1998 comparable quarter average prices),  further decreased by
a 26%  decrease in the average oil and  condensate  sales price which  decreased
revenues by $134,857 (based on current quarter  production).  Production volumes
for natural gas for the three  months  ended March 31, 1999  increased  26% from
1,323 MMcf to 1,668 MMcf,  as compared to the three months ended March 31, 1998.
The increase in natural gas  production  during the three months ended March 31,
1999  increased  revenues by  $838,089,  offset by a 22% decrease in the average
natural gas sales price which  decreased  revenues by $882,130.  The increase in
oil and natural gas  production  was  primarily  due to 42 gross (16.94 net) new
successful  exploratory and development  wells being drilled and completed since
March 31, 1998 offset by normal  production  declines  from existing  wells.  As
described above, included within natural gas revenues for the three months ended
March 31, 1999 and 1998 was  $142,346 and  $36,700,  respectively,  representing
gains from current swap and collar activity.  Hedging  activities  increased the
effective  natural gas sales price by approximately  $0.09 per Mcf and $0.03 per
Mcf, respectively, or 5% and 1%, respectively,  for the three-months ended March
31, 1999 and 1998.

Costs and Operating Expenses

       Lifting  costs for the three  months ended March 31, 1999  increased  29%
from  $370,059 to $479,128 as compared to the three months ended March 31, 1998,
due  primarily to increased oil and natural gas  production.  Lifting costs were
$0.25 per Mcfe and $0.24 per Mcfe for the  three-month  periods  ended March 31,
1999 and 1998, respectively.

                                       12
<PAGE>

       Severance  and ad valorem taxes for the three months ended March 31, 1999
increased  17% from  $301,125 to $352,689 as compared to the three  months ended
March 31, 1998,  due primarily to increased ad valorem  taxes.  Severance and ad
valorem taxes were $0.19 per Mcfe for both  three-month  periods ended March 31,
1999 and 1998, respectively.

       Depletion,  depreciation and amortization  expense ("DD&A") for the three
months ended March 31, 1999 increased 60% from $1.2 million to $1.9 million,  as
compared to the three months ended March 31, 1998.  Included within DD&A for the
three-month  periods  ended  March  31,  1999 and 1998 was $1.7  million  and $1
million,  respectively,  representing  depletion  expense of oil and natural gas
property,  which  increased  by 67%.  Increased  oil and natural gas  production
increased depletion expense by approximately  $206,000 and a 39% increase in the
overall  depletion rate further  increased  depletion  expense by  approximately
$494,000.  The increase in the  depletion  rate was  primarily  attributable  to
abandonments of certain  projects,  prospects and wells at December 31, 1998 and
dry holes drilled since March 31, 1998  contributing  to an overall  increase in
finding  cost.  Depletion  expense  on  a  unit  of  production  basis  for  the
three-month  periods  ended March 31, 1999 and 1998 was $0.90 per Mcfe and $0.65
per Mcfe,  respectively.  The  remaining  increase in DD&A is due  primarily  to
depreciation  of  new  computer  hardware,   software  and  office  improvements
purchased since March 31, 1998 and the amortization of deferred loan cost on the
Credit Facility which was effective in April 1998.

      General and  administrative  expenses  ("G&A") for the three  months ended
March 31, 1999  increased  16% from  $866,311 to $1 million,  as compared to the
three  months  ended  March  31,  1998.   The  increase  in  G&A  was  primarily
attributable  to a $144,000  decrease in overhead and  management  fees received
from  various  management,  operating  and seismic  agreements  during the three
months ended March 31, 1999.  Total overhead and management fees are recorded as
a reduction of G&A and were  approximately  $54,000 and $200,000,  respectively,
for the three months ended March 31, 1999 and 1998.  G&A on a unit of production
basis for the  three-month  periods  ended March 31, 1999 and 1998 was $0.53 per
Mcfe and $0.55 per Mcfe, respectively.

       Unearned  compensation  expense for the three months ended March 31, 1999
decreased from $155,052 to $83,976,  as compared to the three months ended March
31, 1998. The decrease is due to the  resignation of the former CEO and Chairman
of the  Board  during  November  of 1998  whereby  he  vested  in his  remaining
restricted stock grant. The Company charged to expense his unamortized  unearned
compensation upon his resignation.

       Interest  expense for the three  months  ended March 31, 1999 was $38,326
net of amounts capitalized of $225,597.  The increase in interest expense is due
to increased  borrowings  under the Company's  Credit  Facility  since March 31,
1998. The weighted average debt was $12 million for the three months ended March
31, 1999.  There was no debt  outstanding  during the  three-month  period ended
March 31, 1998.

        Interest income for the three months ended March 31, 1999 decreased from
$46,045 to $11,022,  as compared to the three months  ended March 31, 1998.  The
decrease in interest  income is due to the overall  reduction in invested  funds
during the comparable periods.

       Due to the Company  incurring a net loss for the three months ended March
31, 1999 and due to the Company having  significant  deferred tax assets, no tax
benefit (expense) was recorded.  Due to the uncertainty of the Company's ability
to become  profitable in the future an allowance has been provided to offset the
tax benefits of certain tax assets. Should the Company have net income in future
periods  income tax expense will be recorded  upon  utlization  of available tax
assets. Tax expense for the three months ended March 31, 1998 was $333,881.

                                       13
<PAGE>

       For the three months  ended March 31, 1999,  the Company had an operating
loss of $(278,184)  compared to operating income of $906,533 for the three month
period ended March 31, 1998,  primarily due to  significantly  lower natural gas
and oil and condensate prices,  further reduced by increased  operating expenses
and increased DD&A expense  offset by increased oil and natural gas  production.
Net loss was  $(305,488)  for the three months ended March 31, 1999,  or $(0.04)
basic and diluted loss per share, as compared to net income of $2.4 million,  or
$0.31 basic and diluted earnings per share,  ($618,697 before  cumulative effect
of  accounting  change or $0.08 basic and diluted  earnings per share),  for the
three-month period ended March 31, 1998.

LIQUIDITY AND CAPITAL RESOURCES

         The Company had cash and cash equivalents at March 31, 1999 of $259,652
consisting  primarily of  short-term  money market  investments,  as compared to
$272,428 at December 31, 1998.  Working  capital was $(9.1) million at March 31,
1999, as compared to $(8.3) million at December 31, 1998.

         Operating cash flow was approximately $1.7 million and $2.3 million for
the three-month periods ended March 31, 1999 and 1998,  respectively.  Operating
cash flow, a measure of performance for  exploration  and production  companies,
represents cash flows from operating  activities  prior to changes in assets and
liabilities.  Operating  cash flow should not be considered in isolation or as a
substitute  for  net  income,   operating  income,  cash  flows  from  operating
activities or any other measure of financial performance presented in accordance
with generally accepted  accounting  principles or as a measure of profitability
or liquidity.

         During the three months ended March 31, 1999, the Company  continued to
reinvest a  substantial  portion of its cash flows to  increase  its 3-D project
portfolio,  improve  its 3-D  seismic  interpretation  technology  and  fund its
drilling program.  Capital  expenditures during the three months ended March 31,
1999 were  approximately  $3 million as compared to $8.5 million during the same
period in 1998.  The Company  expended  $1.3 million in its drilling  operations
resulting  in the  drilling of 6 gross (2.53 net) wells  during the three months
ended March 31, 1999 as compared to 22 gross  (10.29 net) wells  during the same
period in 1998. Two wells are currently  drilling,  the Varn #2 located in South
Louisiana  and the  Worsham/O'Conner  #1 located in South  Texas.  Land and data
acquisition  expenditures were $1.7 million and were largely attributable to its
Nodosaria  Embayment  3-D  Project  Area  in  South  Louisiana.   Total  capital
expenditures for 1999 are expected to be approximately $18 million.

         Due to the Company's active  exploration and development and technology
enhancement  programs,  the Company has  experienced  and expects to continue to
experience substantial working capital requirements. The Company intends to fund
its 1999 capital  expenditures,  commitments  and working  capital  requirements
through  cash flows from  operations,  available  borrowings  under its existing
Revolving  Credit  Facility,   and  to  the  extent  necessary  other  financing
activities.  To provide  additional  working  capital the Company  continues  to
market a portion  of its  interest  in various  Company  generated  drill  ready
prospects.  Additionally,  the Company is currently evaluating various financing
and refinancing  options as well as  divestitures of certain  non-core and under
performing  assets.  The Company  believes  it will be able to generate  capital
resources and liquidity  sufficient  to fund its capital  expenditures  and meet
such financial obligations as they come due. In the event such capital resources
are not  available to the Company,  its  drilling  and other  activities  may be
curtailed.

Subsequent Event

         On May 6, 1999, the Company  completed a private  offering of 1,400,000
shares of common stock based on a market price of $5.3125 per common share.  The
private offering also provides for warrants, which were purchased for $0.125 per
share,  to acquire an  additional  420,000  shares of common  stock at $5.35 per
share. Total proceeds, net of offering costs, were approximately $7.4 million of
which $4.9 million was used to repay debt under the  Revolving  Credit  Facility
with the remainder to be used to satisfy working capital requirements and fund a
portion of the Company's future exploration program. After the repayment of debt
the Company has available  approximately $1.5 million under its Revolving Credit
Facility for future borrowings.

Revolving Credit Facility

    During July 1995, the Company entered into a revolving  credit facility (the
"Revolving  Credit  Facility") with a bank to finance  temporary working capital
requirements.  The  Revolving  Credit  Facility  provided  up to $20  million in
borrowings  limited by a  borrowing  base,  as defined by the  Revolving  Credit
Facility.  The Revolving  Credit Facility  provided for interest at the lender's
prime rate plus 0.75%. The borrowing base was subject to review by the bank on a
quarterly basis and could be adjusted subject to the provisions of the Revolving
Credit  Facility.  Effective April 1, 1998, the Company amended and restated its
Revolving  Credit  Facility to provide a revolving  line of credit of up to $100
million  bearing  interest  at a rate  equal to prime  or LIBOR  plus  1.5% - 2%
depending on the level of borrowing  base  utilization.  The  Company's  initial
borrowing  base  authorized  by the banks was  approximately  $15  million.  The
Revolving  Credit  Facility  is secured by  substantially  all the assets of the
Company.

      Effective   September  29,  1998,  the  Company  had  its  borrowing  base
redetermined and amended its Revolving Credit  Facility.  The initial  borrowing
base authorized by the bank was $15 million.  Beginning  October 1, 1998, and on
the first day of each month  thereafter,  the borrowing  base was required to be
reduced by $550,000.

      The Revolving Credit Facility provides for certain restrictions, including
but not limited to,  limitations on additional  borrowings and issues of capital
stock, sales of its oil and natural gas properties or other collateral, engaging
in merger or  consolidation  transactions  and  prohibitions  of  dividends  and
certain  distributions  of cash or properties and certain  liens.  The Revolving
Credit Facility also contains certain financial covenants.

     Effective  March 1, 1999, the Company and the Bank amended the Revolving
Credit  Facility to include the following  terms; 1),the initial borrowing base
 is $12 million comprised of a two tranche financing of a $9 million Revolving
Credit Facility and a $3 million term  facility,  2) Beginning May 1, 1999,
and on the first day of each month  thereafter,  the Revolving  Credit  Facility
borrowing  base is required to be reduced by $400,000,  3) 75% of prospect sales
will be used to pay down the term facility with the remaining  unpaid term
facility  balance  maturing on August 31, 1999.  The Company and the Bank also
amended the  Revolving  CreditFacility to replace the financial covenants on a
go forward basis with a Tangible Net Worth Covenant and Fixed Charge Covenant.
TheTangible Net Worth  Covenant  requires that at the end of each quarter the
Company's  Tangible Net Worth be at least 90% of the Company's  actual tangible
networth as reported at December 31, 1998 (or  $33,260,720)  plus 50% of
positive net income and 100% of other  increases in equity for all fiscal
quarters  ending  subsequent to December 31, 1998.  The Fixed Charge  Covenant
requires that at the end of each quarterbeginning  June 30, 1999,  the ratio of
annualized  EBITDA (as defined) to the sum of annualized  interest  expense plus
50% of the quarter end loans  outstanding  must be at least 1.25 to 1.00.
Interest will accrue at a rate of LIBOR plus 1.75% - 2.75% depending on the
borrowing base utilization.

Accounting Change

         The Company uses the  full-cost  method of  accounting  for its oil and
natural gas  properties.  Under this method,  all  acquisition,  exploration and
development costs that are directly  attributable to the Company's  acquisition,
exploration and development  activities are capitalized in a "full-cost pool" as
incurred.  In the second  quarter  of 1998 and  effective  January 1, 1998,  the
Company  changed its method of accounting  for direct  internal  geological  and
geophysical  ("G&G")  costs to one of  capitalization  of such costs,  which are
directly attributable to acquisition, exploration and development activities, to

                                       15
<PAGE>

oil and natural gas property.  Accordingly, the financial results for the period
ended  March 31,  1998  have  been  adjusted  to give  effect  to the  change in
accounting  method  effective  January 1, 1998.  Prior to the change the Company
expensed these costs as incurred.  The Company  believes the  accounting  change
provides  for a better  matching of  revenues  and  expenses  and  enhances  the
comparability  of its results of operations  with those of other oil and natural
gas companies that follow the full cost method of accounting  (See note 1 to the
consolidated financial statements).

Year 2000

         The Company has  completed its  assessment of the year 2000  processing
issues of its internal  technology  systems,  considering  current financial and
accounting,  production,  land and  geological  computer  systems  and  software
utilized by the Company. Due to the need for improved management reporting,  the
Company is in the process of replacing its existing  financial  and  accounting,
production and land applications with new software which is year 2000 compliant.
Implementation  is expected to be completed on or before September 30, 1999 at a
total cost of  approximately  $235,000.  As of March 31,  1999,  the Company has
incurred  approximately  $180,000 converting to its new financial and accounting
system and software with a majority of the remaining  cost to be incurred  prior
to June 30, 1999.  Production  and land  applications  will be operational on or
before  June 30,  1999.  These  costs  have been  funded  from cash  flows  from
operations and the cost of the new software and necessary hardware upgrades have
been capitalized.  Based on assertions made by vendors, the Company believes its
geological systems and software are year 2000 compliant. In addition the Company
is performing other forms of due diligence to ensure that its geological systems
are compliant.

         The Company is also in the process of evaluating  the risk presented by
potential Year 2000  non-compliance  by third  parties.  Because such risks vary
substantially, companies are being contacted based on the estimated magnitude of
risk  posed to the  Company  by their  year  2000  non-compliance.  The  Company
anticipates that these efforts will continue through 1999 and will not result in
significant costs to the Company.

         The  Company's  assessment  of  its  Year  2000  issues  involves  many
assumptions. There can be no assurance that the Company's assumptions will prove
accurate, and actual results could differ significantly from the assumptions. In
conducting its Year 2000 compliance efforts, the Company has relied primarily on
vendor  representations  with  respect  to  internal  computerized  systems  and
representations   from  third  parties  with  which  the  Company  has  business
relationships and has not independently verified  representations.  There can be
no assurance that these representations will prove accurate. A Year 2000 failure
could result in a business  interruption  that  adversely  effects the Company's
business,  financial  condition  or results of  operations.  Although  it is not
currently aware of any likely business disruptions,  the Company is developing a
contingency plan to address and assess the readiness of its material  suppliers,
customers and other  entities as it relates to year 2000  processing  issues and
expects this work to be completed on or before June 30, 1999. The Company is not
insured for this type of loss should a loss occur.

Accounting Pronouncements

     Derivatives - In June 1998, the Financial Accounting Standards Board issued
Statement of Financial  Accounting Standard No. 133,  "Accounting for Derivative
Instruments and Hedging Activity" ("SFAS 133"). SFAS 133 establishes  accounting
and reporting  standards for derivative  instruments and hedging activities that
require an entity to recognize all derivatives as an asset or liability measured
at fair value. Depending on the intended use of the derivatives,  changes in its
fair value will be  reported  in the period of change as either a  component  of
earnings or a component of other comprehensive income.

                                       16
<PAGE>

     SFAS 133 is  effective  for all fiscal  quarters  beginning  after June 15,
1999.  Earlier  application  of SFAS  133 is  encouraged,  but not  prior to the
beginning of any fiscal  quarter that begins  after  issuance of the  statement.
Retroactive application to periods prior to adoption is not allowed. The Company
has not  quantified  the impact of adoption on its  financial  statements or the
date it intends to adopt.

                     COMMON STOCK SUBSCRIPTION AGREEMENT

         THIS COMMON STOCK  SUBSCRIPTION  AGREEMENT (the "Agreement") is made as
of  April  30,  1999,  by and  among  EDGE  PETROLEUM  CORPORATION,  a  Delaware
corporation  (the  "Company"),   and  those  persons  set  forth  on  Exhibit  A
(collectively the "Purchasers" and each individually a "Purchaser").

                                    SECTION 1

                     Authorization and Sale of Common Stock

         1.1 Authorization.  The Company has authorized the sale and issuance of
up to  1,500,000  shares of its  Common  Stock,  $.01 par  value per share  (the
"Common  Stock")  and up to  450,000  warrants  to  purchase  Common  Stock (the
"Warrants")  and  450,000  shares of Common  Stock to be issued  pursuant to the
Warrants.

         1.2 Sale of Securities. Subject to the terms and conditions hereof, the
Company will issue and sell to the Purchasers and the Purchasers  severally will
buy from the Company the number of shares of Common Stock (the  "Shares") in the
respective aggregate amounts set forth opposite each Purchaser's name on Exhibit
A  (together  with,  in the case of each such  Share,  .3 of a  Warrant  for the
purchase of a share of Common Stock) at a per share  purchase price set forth on
Exhibit A;  provided  that no  fractional  Warrants or Warrants  for  fractional
shares shall be issued and the respective amounts of Warrants being so purchased
in tandem  with the  Shares  are set forth  opposite  each  Purchaser's  name on
Exhibit A. Each  Warrant  entitles  the holder to  purchase  one share of Common
Stock and shall be in the form attached to the warrant  agreement  (the "Warrant
Agreement")  set forth in Exhibit B. The Shares and the  Warrants  are  together
referred to herein as "Securities."

                                    SECTION 2

                       Closing Date; Payment and Delivery

         2.1 Closing Date.  The closing under this Agreement with respect to the
sale of the  Securities  pursuant  to  Section  1.2  hereof  shall take place in
Houston,  Texas at 11:00  a.m.  (Houston  time) on May 6, 1999 or at such  other
times, dates and places upon which the Company and the Purchasers shall mutually
agree  (the date of the  Closing  is  hereinafter  referred  to as the  "Closing
Date").  The Company may make individual and different  arrangements  separately
with each  Purchaser  as to Closing,  including  with respect to delivery of the
Shares and Warrants and transmittal of purchase price.
                                                     -1-
         2.2 Payment and Delivery. At the Closing, each Purchaser shall transmit
the aggregate  purchase  price set forth on Exhibit A opposite that  Purchaser's
name in  immediately  available  funds by wire  transfer to the Company.  At the
Closing the Company will deliver to the Purchasers certificates representing the
Shares and the  Warrants.  The  certificates  for  Shares  shall be subject to a
legend  restricting  transfer  under the Securities Act of 1933, as amended (the
"Securities Act"), and referring to restrictions on transfer herein, such legend
to be substantially as follows:

THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND
HAVE NOT BEEN  REGISTERED  UNDER THE  SECURITIES  ACT OF 1933, AS AMENDED OR ANY
STATE  SECURITIES LAW. SUCH SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE
OF SUCH REGISTRATION OR AN OPINION OF COUNSEL  SATISFACTORY TO THE COMPANY AS TO
THE AVAILABILITY OF AN EXEMPTION FROM REGISTRATION THAT SUCH REGISTRATION IS NOT
REQUIRED AND THAT ANY PROSPECTUS DELIVERY  REQUIREMENTS ARE NOT APPLICABLE.  THE
SHARES WERE PURCHASED UNDER AN AGREEMENT THAT INCLUDES  ADDITIONAL  RESTRICTIONS
ON THEIR  TRANSFER  AND COPIES OF SUCH  AGREEMENT  MAY BE OBTAINED AT NO COST BY
WRITTEN  REQUEST  MADE  BY THE  HOLDER  OF  RECORD  OF THIS  CERTIFICATE  TO THE
SECRETARY OF THE COMPANY AT THE PRINCIPAL EXECUTIVE OFFICES OF THE COMPANY.
                                       3
<PAGE>
The Shares and the Warrants may also include any legend  required under the laws
of any state or other jurisdiction.  The certificates for Warrants and shares of
Common Stock issuable upon exercise of the Warrants (the "Warrant  Shares") will
include such legend as is specified in the Warrant Agreement.

                                    SECTION 3

                  Representations and Warranties of the Company

         Except as set forth on the Schedule of  Exceptions  attached  hereto as
Exhibit C, the Company  hereby  represents  and  warrants to the  Purchasers  as
follows:

         3.1  Organization.  The Company is a  corporation  duly  organized  and
validly existing under the laws of the State of Delaware and is in good standing
under such laws. The Company has requisite corporate power and authority to own,
lease and operate its  properties  and assets,  and to carry on its  business as
presently conducted and as proposed to be conducted. The Company is qualified to
do business as a foreign corporation in each jurisdiction in which the ownership
of its  property  or the nature of its  business  requires  such  qualification,
except where failure to so qualify would not have a material  adverse  effect on
the  Company  and its  Subsidiaries  (as  defined  herein),  taken as a whole (a
"Material  Adverse  Effect").  As used in this Agreement,  the word "Subsidiary"
means  any   corporation  or  other   organization,   whether   incorporated  or
unincorporated,  of which the Company directly or indirectly owns or controls at
least a majority  of the  securities  or other  interests  having by their terms
ordinary  voting  power to elect a majority of the board of  directors or others
performing   similar  functions  with  respect  to  such  corporation  or  other
organization, or any organization of which such party is a general partner.

         3.2  Capitalization.  The  authorized  capital  stock  of  the  Company
consists of  25,000,000  shares of Common  Stock,  $.01 par value per share,  of
which  7,770,302  shares were issued and  outstanding  as of April 5, 1999,  and
5,000,000  shares of  Preferred  Stock,  $.01 par value per share,  no shares of
which are issued and  outstanding  as of the date  hereof.  All such  issued and
outstanding  shares of Common Stock have been duly authorized and validly issued
and are fully paid and  nonassessable.  As of December 31, 1998, the Company had
1,200,000  shares of Common Stock reserved for issuance under its Incentive Plan
and options to purchase  680,133  shares of Common  Stock and 248,384  shares of
restricted  Common  Stock  have  been  granted  and are  outstanding  under  its
Incentive  Plan.  Options for the purchase of an  additional  48,922  shares and
200,000 shares of Common Stock are also  outstanding and were issued to James D.
Calaway and John Elias,  respectively.  Except as described  in this  Agreement,
there are no other options, warrants, conversion privileges or other contractual
rights presently outstanding to purchase or otherwise acquire any authorized but
unissued shares of the Company's capital stock or other securities.

         3.3  Authorization.  The Company  has all  corporate  right,  power and
authority  to enter  into this  Agreement  and to  consummate  the  transactions
contemplated  hereby.  All  corporate  action  on the part of the  Company,  its
directors and stockholders necessary for the authorization,  execution, delivery
and  performance  of this  Agreement by the Company,  the  authorization,  sale,
issuance and delivery of Securities and the Warrant  Shares and the  performance
of the Company's  obligations  hereunder has been taken. This Agreement has been
duly  executed and delivered by the Company and  constitutes a legal,  valid and
binding obligation of the Company, enforceable against the Company in accordance
with its terms,  subject to laws of general application  relating to bankruptcy,
insolvency  and the  relief  of  debtors  and  rules of law  governing  specific
performance,  injunctive relief or other equitable remedies,  and to limitations
of public policy.  Upon the issuance and delivery of the Shares as  contemplated
by  this  Agreement,   the  Shares  will  be  validly  issued,  fully  paid  and
nonassessable.  Upon the  issuance  and  delivery  of the  Warrant  Shares  upon
exercise of the Warrants in accordance with the Warrant  Agreement,  the Warrant
Shares will be validly issued,  fully paid and  nonassessable.  The issuance and
sale of the Shares contemplated hereby and the Warrant Shares upon conversion of

                                       4
<PAGE>

the  Shares  will not give  rise to any  preemptive  rights  or  rights of first
refusal on behalf of any person.

         3.4 Subsidiaries.  Each Subsidiary is a corporation or partnership duly
organized  and  validly   existing  under  the  laws  of  its   jurisdiction  of
incorporation  or  organization  and is in good standing  under such laws.  Each
Subsidiary  has the requisite  corporate or  partnership  power and authority to
own, lease and operate its  properties and assets,  and to carry on its business
as presently conducted and as proposed to be conducted.  Each Subsidiary is duly
qualified  to do  business  as a  foreign  corporation  or  partnership  in each
jurisdiction  in which  the  ownership  of its  property  or the  nature  of its
business  requires  such  qualification,  except where the failure to so qualify
would not have a material  adverse  effect on the Company  and its  Subsidiaries
taken as a whole.

         3.5 No  Conflict.  Subject to  compliance  with such  filings as may be
required to be made with the Securities and Exchange Commission (the "SEC"), any
state or foreign securities regulatory authority, and the Nasdaq National Market
System  ("Nasdaq"),  the execution and delivery of this  Agreement does not, and
the consummation of the transactions  contemplated hereby will not result in any
violation of, or default (with or without notice or lapse of time, or both),  or
give  rise  to a right  of  termination,  cancellation  or  acceleration  of any
material obligation or to a loss of a material benefit,  under, any provision of
the  Restated  Certificate  of  Incorporation  or Bylaws of the  Company  or any
mortgage, indenture, lease or other agreement or instrument,  license, judgment,
order, decree,  statute,  law, ordinance,  rule or regulation  applicable to the
Company or a Subsidiary,  its  properties  or assets,  the effect of which would
have a Material Adverse Effect on the financial condition,  results of operation
or prospects of the Company and its Subsidiaries taken as a whole, or materially
impair  or  restrict  the  Company's   power  to  perform  its   obligations  as
contemplated hereby.

         3.6  Accuracy  of  Reports.  All  reports  required  to be filed by the
Company  since the  beginning  of the  Company's  current  fiscal year under the
Securities  Exchange Act of 1934,  as amended (the  "Exchange  Act"),  copies of
which have been furnished to the Purchasers (collectively,  the "Reports"), have
been duly filed with the SEC,  complied at the time of filing,  in all  material
respects with the  requirements of their  respective  forms,  and, except to the
extent updated or superseded by any materials  supplied to the Purchasers or any
subsequently filed report, were complete and correct in all material respects as
of the dates at which the information  was furnished,  and contained (as of such
dates) no untrue  statement  of a  material  fact or omitted to state a material
fact necessary in order to make the statements  contained  therein,  in light of
the circumstances under which they were made, not misleading.

         3.7  Registration  Rights.  Except as set forth in this Agreement,  the
Company is not under any obligation to register any of its presently outstanding
securities or any of its securities which may hereafter be issued.

         3.8 Governmental Consents,  etc. No consent,  approval or authorization
of or designation,  declaration or filing with any governmental authority on the
part of the Company is required in connection with the execution and delivery of
this Agreement,  the offer,  sale or issuance of the Shares, or the consummation
of any other  transaction  contemplated  hereby,  except such  filings as may be
required  to be made with the SEC and Nasdaq and with any state or foreign  blue
sky or securities regulatory authority.

         3.9  Litigation.  There is no pending or, to the best of the  Company's
knowledge,  threatened lawsuit,  administrative proceeding,  arbitration,  labor
dispute or governmental  investigation  ("Litigation") to which the Company or a
Subsidiary is a party or by which any material  portion of its assets taken as a
whole may be bound,  and which  Litigation if adversely  determined would have a
Material Adverse Effect; provided that the disclosure of litigation on Exhibit C
shall not be deemed an admission that such litigation is material.

         3.10  Investment  Company.  The Company is not an "investment  company"
within the meaning of such term under the Investment Company Act of 1940 and the
rules and regulations of the SEC thereunder.

         3.11 Financial  Statements.  The audited  consolidated balance sheet of
the  Company  at  December  31,  1998,  and  the  related  audited  consolidated
statements of operations,  cash flows, and  stockholders'  equity of the Company
for the  fiscal  year  then  ended,  copies  of which  have  been  furnished  to
Purchasers,  fairly present the financial condition of the Company at such dates
and the results of the  operations  of the Company for the periods ended on such
dates,  and such  consolidated  balance  sheets and  consolidated  statements of
operations,  cash flows,  and  stockholders'  equity were prepared in accordance
with United States generally  accepted  accounting  principles  ("GAAP") (and in
compliance  with the  regulations  promulgated  by the SEC).  Since December 31,
1998, no event has occurred that would have a Material  Adverse Effect except as
set forth in the Reports or on the exhibits or schedules hereto.

         3.12 Pension  Plans.  All Plans (as defined  herein) are in  compliance
with all applicable provisions of the Employee Retirement Income Security Act of
1974, as amended from time to time  ("ERISA")  and the Internal  Revenue Code of
1986, as amended,  and any successor statute (the "Code"),  except to the extent
any noncompliance would not have a Material Adverse Effect. No Termination Event
(as defined  herein) has  occurred  with  respect to any Plan.  No  "accumulated
funding  deficiency"  (as  defined in Section  302 of ERISA) has  occurred  with
respect to any Plan.  Neither the Company nor any member of the Controlled Group
(as  defined  herein)  has  had  a  complete  or  partial  withdrawal  from  any
Multiemployer  Plan (as  defined  herein)  for  which  there  is any  withdrawal
liability that could  reasonably be expected to have a Material  Adverse Effect.
As used in  this  Section,  "Controlled  Group"  shall  mean  all  members  of a
controlled  group of corporations  and all trades or businesses  (whether or not
incorporated) under common control which, together with the Company, are treated
as a single employer under Section 414 of the Code;  "Multiemployer  Plan" shall
mean a "multiemployer  plan" as defined in Section  4001(a)(3) of ERISA;  "Plan"
shall  mean  any  employee  benefit  plan  (other  than  a  Multiemployer  Plan)
maintained  for employees of the Company or any member of the  Controlled  Group
and  covered by Title IV of ERISA or subject to the  minimum  funding  standards
under  Section  412 of the  Code;  and  "Termination  Event"  shall  mean  (a) a
Reportable  Event (as defined in Title IV of ERISA) described in Section 4043 of
ERISA and the regulations  issued  thereunder (other than a Reportable Event not
subject to the  provision  for 30-day  notice to the  Pension  Benefit  Guaranty
Corporation or any entity  succeeding to any or all of its functions under ERISA
(the "PBGC") under such  regulations),  (b) the withdrawal of the Company from a
Plan during a plan year in which it was a  "substantial  employer" as defined in
Section 4001(a) (2) of ERISA,  (c) the filing of a notice of intent to terminate

PBGC,  or (e) any other  event or  condition  which  constitutes  grounds  under
Section 4042 of ERISA for the termination of, or the appointment of a trustee to

to any  liability  under  ERISA if the  Company or any member of the  Controlled
Group  has  received  notice  that any  Multiemployer  Plan is  insolvent  or in
reorganization.

permits and with all other requirements of applicable environmental laws, except

Act or other environmental law) that would have a Material Adverse Effect.

permits,  licenses,  patents and other rights and privileges necessary to permit
them to own their  property and conduct their  business,  except for those,  the
non-obtainment  of which  would not  reasonably  be  expected to have a Material
Adverse  Effect.  The Company  and the  Subsidiaries  manage and  operate  their
business in material  compliance with all applicable  legal  requirements and in
accordance with good industry practices,  except where such failure to manage or
operate would not reasonably be expected to have a Material Adverse Effect.

the date  hereof,  (a)  obligated  in any  material  respect  by  virtue  of any
prepayment made under any contract  containing a  "take-or-pay"  or "prepayment"

future date without receiving full payment therefor at the time of delivery, and

Company's consolidated oil and gas properties is subject to, balancing rights of
third parties or subject to balancing  duties under  governmental  requirements,
except as to such  matters  for  which  the  Company  has  established  monetary
reserves  adequate in amount in accordance with GAAP to satisfy such obligations
and has segregated such reserves from its other accounts.

         3.16 Patents,  Trademarks and Other Intangible  Assets. The Company and
its Subsidiaries  own or possess adequate  licenses or other valid rights to use
all  patents,  patent  rights,  trademarks,  trademark  rights  and  proprietary
information used or held for use in connection with their respective  businesses
as currently  being  conducted,  except where the failure to own or possess such
licenses and other rights would not have,  individually  or in the aggregate,  a
Material Adverse Effect , and there are no assertions or claims  challenging the
validity of any of the foregoing  which are likely to have,  individually  or in
the aggregate,  a Material Adverse Effect.  The conduct of the Company's and its
Subsidiaries'  respective  businesses as currently  conducted  does not conflict
with any patents, patent rights, licenses,  trademarks,  trademark rights, trade
names,  trade  name  rights or  copyrights  of others in any way likely to have,
individually  or in the  aggregate,  a  Material  Adverse  Effect.  There  is no
material infringement of any proprietary right owned by or licensed by or to the
Company or any of its Subsidiaries  which is likely to have,  individually or in
the aggregate, a Material Adverse Effect.

         3.17 Title to Properties;  Liens and  Encumbrances.  Except pursuant to
the Amended and Restated Credit  Agreement to which the Company,  Edge Petroleum

                                    SECTION 4

                Representations and Warranties of the Purchasers

         Each  Purchaser  hereby  represents  and  warrants  to the  Company  as
follows:

         4.1  Investment.  The Purchaser is acquiring the Shares for  investment
for its own account,  not as a nominee or agent,  and not with a view to, or for
resale in connection with, any distribution thereof. The Purchaser  acknowledges
the Company's  obligation to file a  registration  statement with respect to the
Shares as set forth in Section 8 of this Agreement,  the  effectiveness of which
registration  statement  may be  required  for the  resale  of the  Shares.  The
Purchaser has not offered or sold any portion of the Shares to be acquired by it
and has no present intention of reselling or otherwise  disposing of any portion
of such Shares either  currently or after the passage of a fixed or determinable
period of time or upon the  occurrence  or  nonoccurrence  of any  predetermined
event or circumstance,  and in particular the Purchaser has no current intention
to resell the Registrable Securities under such registration statement nor would
it have such intention if such  registration  statement were effective as of the
date of purchase.  The Purchaser  understands  that  investment in the Shares is
subject to a high  degree of risk and that the Shares  have not been  registered
under  the  Securities  Act,  by  reason  of  a  specific   exemption  from  the
registration  provisions of the Securities  Act which depends upon,  among other
things,  the bona fide nature of Purchaser's  investment intent and the accuracy
of  the  Purchaser's   representations   as  expressed  herein.   The  Purchaser
acknowledges  and  understands  that  it must  bear  the  economic  risk of this
investment  for an  indefinite  period of time  because  the Shares must be held
indefinitely  until  subsequently   registered  under  the  Securities  Act  and
applicable  state  and  other  securities  laws  or  unless  an  exemption  from
registration is available.  The Purchaser understands that any transfer agent of
the Company will be issued stop-transfer instructions with respect to the Shares
unless such transfer is  subsequently  registered  under the  Securities Act and
applicable  state and other  securities  laws or unless an  exemption  from such
registration  is  available.  The  Purchaser  has  experience  in analyzing  and
investing  in entities  like the Company,  it can bear the economic  risk of its
investment,  including  the full  loss of its  investment,  and by reason of its
business or financial  experience or the business or financial experience of its
professional  advisors  has the capacity to evaluate the merits and risks of its
investment  and protect its own interest in connection  with the purchase of the
Shares from the Company at the Closing. The Purchaser is a resident of the State
set  forth  opposite  such  Purchaser's  name on  Exhibit  A. If  other  than an
individual,  the  Purchaser  was not  organized for the purpose of acquiring the
Shares.

         4.2 Accredited Investor. It is an "accredited investor" as such term is
defined in SEC  Regulation  D. It has  accurately  completed  the  questionnaire
attached hereto as Exhibit D.

         4.3  Authority.  The  Purchaser  has all right,  power and authority to
enter  into this  Agreement  and to  consummate  the  transactions  contemplated
hereby. This Agreement has been duly executed and delivered by the Purchaser and
constitutes a legal, valid and binding obligation of the Purchaser,  enforceable
against the Purchaser in accordance  with its terms,  subject to laws of general
application  relating to  bankruptcy,  insolvency  and the relief of debtors and
rules  of  law  governing  specific  performance,  injunctive  relief  or  other
equitable remedies,  and to limitations of public policy.  Subject to compliance
with such  filings as may be required  to be made with the SEC and  Nasdaq,  the
execution  and delivery of this  Agreement do not, and the  consummation  of the
transactions  contemplated  hereby  will  not,  conflict  with or  result in any
violation  of any  obligation  under any  provision  of the  charter  documents,
limited liability company agreement, partnership agreement or Bylaws, if any, of
the  Purchaser  or  any  mortgage,   indenture,  lease  or  other  agreement  or
instrument,  license,  judgment, order, decree, statute, law, ordinance, rule or
regulation applicable to the Purchaser.

         4.4 Government Consents, etc. No consent,  approval or authorization of
or  designation,  declaration or filing with any  governmental  authority on the
part of the  Purchaser is required in  connection  with the valid  execution and
delivery of this Agreement,  the purchase of the Shares,  or the consummation of
any  other  transaction  contemplated  hereby,  except  such  filings  as may be
required to be made with the SEC.
                                       10

         4.5 Investigation;  No General Solicitation. The Purchaser has received
a copy of the Reports.  The  Purchaser has had a reasonable  opportunity  to ask
questions  relating to and  otherwise  discuss the terms and  conditions  of the
offering and the other  information  set forth in the Reports and this Agreement
and the Company's business,  management and financial affairs with the Company's
management,  customers  and  other  parties,  and  the  Purchaser  has  received
satisfactory  responses to the Purchaser's  inquiries.  The Purchaser has relied
solely  upon the  information  provided  by the  Company in the Reports and this
Agreement  in  making  the  decision  to  invest in the  Shares.  To the  extent
necessary,  the  Purchaser has retained,  at the expense of the  Purchaser,  and
relied upon appropriate  professional  advice regarding the investment,  tax and
legal merits and  consequences  of this Agreement and its purchase of the Shares
hereunder.  The Purchaser disclaims and disavows any reliance upon Raymond James
& Associates  Inc. in  connection  with the  Purchaser's  purchase of Shares and
Warrants.  The Purchaser has relied solely on its own independent  investigation
before  deciding to enter into the purchase of Shares and Warrants  contemplated
hereby.

         4.6 Short Selling.  Purchaser has not prior to the date hereof directly
or indirectly, through related parties, affiliates or otherwise (a) sold "short"
or "short against the box" (as those terms are generally  understood) any equity
security of the  Company;  or (b)  otherwise  engaged in any  transaction  which
involves  hedging of its position  in, or reducing of its economic  exposure to,
the securities of the Company,  and it will not until the date the  Registration
Statement  (as defined  herein) is declared  effective  by the SEC take any such
actions described in (a) or (b) of this Section 4.6.

         4.7 Affiliate Status.  Unless the Purchaser has otherwise  notified the
Company in writing,  the  Purchaser  is not, and has not been within the 90 days
prior to the Closing Date, an officer, director, employee, agent or affiliate of
the Company, or, to the Purchaser's knowledge,  any other Purchaser.  Unless the
Purchaser has otherwise notified the Company in writing,  the Purchaser is not a
broker or dealer of securities, an employee,  officer or director of the Company
nor prior to the Closing Date is the  Purchaser  the  beneficial  owner of 5% or
more of the Common Stock of the Company.

by such Holder.

                                    Covenants

         8.1      Registration Rights.

                  (a) Registration.  No later than 30 days following the Closing
Date,  the  Company  will  file  a  registration  statement  (the  "Registration
Statement")  on Form S-3 with the SEC and will use its  reasonable  best efforts
for such Registration Statement to be declared effective by the SEC. The Company
will use its reasonable best efforts to effect the registration,  qualifications
or compliances  (including,  without  limitation,  the execution of any required
undertaking to file post-effective amendments,  appropriate qualifications under
applicable blue sky or other state  securities  laws and appropriate  compliance
with  applicable  securities  laws,  requirements  or  regulations) as may be so
reasonably requested and as would permit or facilitate the sale and distribution
of all Registrable Securities;  provided that the Company shall not be obligated
to take any  action to effect  any such  state  registration,  qualification  or
compliance pursuant to this subsection 8.1(a) in any particular  jurisdiction in
which the Company  would be required to execute a general  consent to service of
process in effecting such  registration,  qualification or compliance unless the
Company  is  already  subject  to  service  or is  required  to  qualify in such
jurisdiction,  as the  case  may  be,  and  except  as may  be  required  by the
Securities Act.

                                      13
<PAGE>

                  (b)  Expenses  of  Registration.   All  Registration  Expenses
incurred  in  connection  with any  registration,  qualification  or  compliance
pursuant  to  subsection  8.1(a)  shall  be borne by the  Company.  All  Selling
Expenses  relating  to the sale of  securities  registered  by or on  behalf  of
Holders  shall be borne by such  Holders  pro rata on the basis of the number of
securities  so  registered   except  to  the  extent  such  Selling  Expense  is
specifically attributable to one Holder, in which case it shall be borne by such
Holder.

                  (c) Registration Procedures.  In the case of the registration,
qualification or compliance  effected by the Company pursuant to this Agreement,
the Company will, upon reasonable  request,  inform each Holder as to the status
of such registration,  qualification and compliance.  At its expense the Company
will during such time as the Holder holds Registrable Securities:

                           (i)      use  its  reasonable  best  efforts  to keep
such   registration,   and  any qualification  or  compliance  under  state
securities  laws which the  Company determines to obtain,  effective  until at
least the second  anniversary  of the Closing Date or until the Holders have
completed the  distribution  described in the registration statement relating
thereto, whichever first occurs;

                          (ii)     furnish such number of  prospectuses  and
other documents  incident  thereto as the Holders from time to time may
reasonably request;

                         (iii)     use its reasonable best efforts to register
or qualify such Registrable  Shares under such other securities or blue sky laws
of such jurisdictions as any Holder reasonably  requests  and do any and all
other  acts and  things  which  may be reasonably  necessary  or  advisable  to
enable  such Holder to  consummate  the disposition  of  the  Registrable
Securities  owned  by  such  Holder  in  such jurisdictions;  provided, that the
Company  will not be required to (A) qualify generally  to do business in any
jurisdiction  where it would not  otherwise be required to qualify but for this
Section 8.1(c), or(B subject itself to income taxation in any such jurisdiction;

                          (iv)     notify  each  Holder  of  such  Registrable
Securities,  at  any  time  when a prospectus  relating  thereto is required to
be delivered  under the  Securities Act, of the happening of any event as a
result of which the prospectus  included in such registration statement contains
an untrue statement of a material fact or omits any fact necessary to make the
statements therein not misleading,  and, at the request of any such Holder,  the
Company  will  prepare a  supplement  or amendment to such prospectus so that,
as thereafter  delivered to the purchasers of such  Registrable  Securities,
such  prospectus  will not  contain an untrue statement  of a material  fact or
omit to state any fact  necessary  to make the
statements therein not misleading;

                           (v)      cause  all  such  Registrable  Securities
to  be  listed  or  quoted  on  each securities  exchange or automated quotation
system on which  similar  securities  issued by the Company are then
listed or quoted; and

                           (vi)     appoint a transfer agent and registrar for
all such Registrable  Securities not later than the effective date of such
Registration Statement.

The period of time during  which the Company is required  hereunder  to keep the
Registration  Statement  effective  is referred  to herein as "the  Registration
Period."

                  (d) Delay of Registration.  The Holders shall have no right to
take any action to restrain, enjoin or otherwise delay any registration pursuant
to subsection  8.1(a) hereof as a result of any controversy  that may arise with
respect to the interpretation or implementation of this Agreement.

                  (e)      Indemnification.

                           (i)     To the extent  permitted  by law, the Company
will  indemnify each Holder and each person  controlling  such Holder within the
meaning  of  Section  15 of the  Securities  Act,  with  respect  to  which  any
registration,  qualification  or compliance  has been effected  pursuant to this
Agreement,  and each person who controls any  underwriter  within the meaning of
Section 15 of the Securities Act (each an  "Indemnitee"),  against all expenses,
claims,  losses,  damages  and  liabilities  (or  actions in  respect  thereof),
ncluding  any  of the  foregoing  incurred  in  settlement  of  any  litigation,
commenced or  threatened,  arising out of or based on any untrue  statement of a
material fact  contained in any  registration  statement,  prospectus,  offering
circular or other document, or any amendment or supplement thereof,  incident to
any such registration,  qualification or compliance, or based on any omission to
state therein a material fact required to be stated therein or necessary to make
the statements  therein not  misleading,  and will reimburse each Indemnitee for
reasonable legal and any other expenses  reasonably  incurred in connection with
investigating, preparing or defending any such claim, loss, damage, liability or
action;  provided  that the Company will not be liable to any  Indemnitee in any
such  case to the  extent  that any  untrue  statement  or  omission  is made in
reliance  upon and in  conformity  with  written  information  furnished  to the
Company by an instrument  duly executed by or on behalf of such  Indemnitee  and
stated to be specifically for use in preparation of such registration statement,
prospectus,  offering circular or other document;  and provided that the Company
will not be liable in any such case where the expense,  claim,  loss,  damage or
liability  arises out of or is  related  to the  failure of the Holder to comply
with the covenants and agreements  contained in this Agreement  respecting sales
of  Registrable  Securities;  and,  provided,  further,  that the indemnity with
respect to any  preliminary  prospectus  shall not apply to the extent  that any
such claim,  loss, damage or liability results from the fact that a current copy
of the prospectus was not sent or given to the person asserting any such claims,
losses,  damages or liabilities at or prior to the written  confirmation  of the
sale of the Registrable Securities confirmed to such person if such current copy
of the prospectus  would have cured the defect giving rise to such claim,  loss,
damage or liability.

                           (ii)     To the extent  permitted by law, each Holder
 will  severally,  if  Registrable
Securities  held by such Holder are included in the  securities as to which such
registration,  qualification  or  compliance  is being  effected,  indemnify the
Company and each person who controls the Company or such underwriter  within the
meaning of Section 15 of the Securities Act, against all claims, losses, damages
and liabilities (or actions in respect thereof),  including any of the foregoing
incurred in settlement of any litigation,  commenced or threatened,  arising out
of or  based  on any  untrue  statement  of a  material  fact  contained  in any
registration statement,  prospectus, offering circular or other document, or any
amendment   or   supplement   thereof,   incident  to  any  such   registration,
qualification  or  compliance,  or based on any  omission  to  state  therein  a
material fact required to be stated  therein or necessary to make the statements
therein not misleading,  or any failure by a Holder to comply with the covenants
or agreements contained in this Agreement respecting the Registrable  Securities
and will reimburse the Company, such directors,  officers, employees,  partners,
legal  counsel  and  accountants  for  reasonable  legal and any other  expenses
reasonably incurred in connection with investigating, preparing or defending any
such claim, loss,  damage,  liability or action, in each case to the extent, but
only to the extent,  that such untrue  statement or omission is made in reliance
upon and in conformity with written  information  furnished to the Company by an
instrument  duly  executed  by or on  behalf  of the  Holder  and  stated  to be
specifically for use in preparation of such registration statement,  prospectus,
offering circular or other document; provided that the indemnity with respect to
any preliminary  prospectus shall not apply to the extent that such claim, loss,
damage or liability  results from the fact that a current copy of the prospectus
                                       15
<PAGE>

was not sent or given to the person  asserting any such claim,  loss,  damage or
liability at or prior to the written confirmation of the sale of the Registrable
Securities confirmed to such person if such current copy of the prospectus would
have cured the defect  giving  rise to such loss,  claim,  damage or  liability.
Notwithstanding the foregoing, in no event shall a Holder be liable for any such
claims,  losses,  damages or liabilities  in excess of the proceeds  received by
such Holder in the offering, except in the event of fraud by such Holder.

                           (iii) Each party  entitled to  indemnification  under
this subsection 8.1(e) (the
"Indemnified  Party")  shall  give  notice  to the  party  required  to  provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the  Indemnifying  Party to assume  the  defense of any such claim or any
litigation  resulting  therefrom,  provided  that  counsel for the  Indemnifying
Party,  who shall  conduct  the  defense of such claim or  litigation,  shall be
approved by the  Indemnified  Party (whose  approval shall not  unreasonably  be
withheld),  and the  Indemnified  Party may  participate in such defense at such
party's expense,  and provided further that the failure of any Indemnified Party
to give notice as provided  herein shall not relieve the  Indemnifying  Party of
its obligations under this Agreement,  unless such failure is prejudicial to the
Indemnifying Party in defending such claim or litigation.  An Indemnifying Party
shall not be liable for any  settlement of an action or claim  effected  without
its written consent (which consent will not be unreasonably withheld).

                           (iv)     If the  indemnification  provided  for in
this  subsection  8.1(e) is held by a
court of competent  jurisdiction to be unavailable to an Indemnified  Party with
respect to any loss,  liability,  claim,  damage or expense referred to therein,
then the  Indemnifying  Party, in lieu of indemnifying  such  Indemnified  Party
thereunder,  shall  contribute to the amount paid or payable by such Indemnified
Party as a result of such  loss,  liability,  claim,  damage or  expense in such
proportion as is appropriate  to reflect the relative fault of the  Indemnifying
Party on the one hand and of the  Indemnified  Party on the other in  connection
with the statements or omissions which resulted in such loss, liability,  claim,
damage or expense as well as any other relevant  equitable  considerations.  The
relative fault of the Indemnifying  Party and of the Indemnified  Party shall be
determined by reference  to, among other  things,  whether the untrue or alleged
untrue  statement of a material  fact or the  omission to state a material  fact
relates to information  supplied by the Indemnifying Party or by the Indemnified
Party and the parties'  relative  intent,  knowledge,  access to information and
opportunity to correct or prevent such statement or omission.

                  (f )     Covenants of Holders.

                           (i)      Each Holder  agrees  that,  upon  receipt of
 any notice from the Company of the
happening of any event requiring the preparation of a supplement or amendment to
a prospectus relating to Registrable Securities so that, as thereafter delivered
to the  Holders,  such  prospectus  will not  contain an untrue  statement  of a
material fact or omit to state any material  fact required to be stated  therein
or necessary to make the  statements  therein not  misleading,  each Holder will
forthwith  discontinue  disposition  of Registrable  Securities  pursuant to the
registration  statement  contemplated by subsection  8.1(a) until its receipt of
copies of the  supplemented  or amended  prospectus  from the Company and, if so
directed by the Company,  each Holder  shall  deliver to the Company all copies,
other than  permanent  file  copies  then in such  Holder's  possession,  of the
prospectus  covering such Registrable  Securities current at the time of receipt
of such notice.

                           ii)      Each Holder severally agrees for a period of
 time (not to exceed 90 days) from
the  effective  date of any  registration  (other than a  registration  effected
solely to implement an employee  benefit  plan) of securities of the Company for
any  underwritten  offering  in which  securities  of the Company are sold (upon
request of the Company or of the underwriters managing any underwritten offering
to the Company's  securities) not to sell,  make any short sale of, loan,  grant
any  option  for the  purchase  of,  or  otherwise  dispose  of any  Registrable
Securities  or any other stock of the Company  held by such  Holder,  other than
shares of  Registrable  Securities  included in such  registration,  without the
prior written consent of the Company or such  underwriters,  as the case may be;
                                       16
<PAGE>

provided that this  obligation  is subject to the  condition  that all executive
officers and directors of the Company shall enter into similar agreements.  Each
Holder  agrees to suspend,  upon  request of the  Company,  any  disposition  of
Registrable  Securities  pursuant to the  Registration  Statement and prospectus
contemplated  by subsection  8.1(a) during any period,  not to exceed one 45-day
period per circumstance or development and not to exceed 90 days in any 12-month
period, when the Company determines in good faith that offers and sales pursuant
thereto  should not be made by reason of the presence of  material,  undisclosed
circumstances or developments with respect to which the disclosure that would be
required in such a prospectus is premature,  would have an adverse effect on the
Company or is otherwise  inadvisable.  Any such request by the Company  shall be
held confidential by the Holder.

                           (iii)    Each  Holder  agrees  to notify the Company,
  at any time  when a  prospectus
relating to the  registration  statement  contemplated  by subsection  8.1(a) is
required to be delivered by it under the  Securities  Act, of the  occurrence of
any event relating to the Holder which requires the  preparation of a supplement
or  amendment  to such  prospectus  so  that,  as  thereafter  delivered  to the
purchasers of Registrable Securities, such prospectus will not contain an untrue
statement of a material  fact or omit to state any material  fact required to be
stated  therein or  necessary  to make the  statements  therein  not  misleading
relating to the Holder,  and each Holder shall  promptly  make  available to the
Company the  information to enable the Company to prepare any such supplement or
amendment.  Each Holder also agrees that,  upon  delivery of any notice by it to
the  Company of the  happening  of any event of the kind  described  in the next
preceding  sentence of this  subsection,  the Holder will forthwith  discontinue
disposition of Registrable  Securities  pursuant to such registration  statement
until its  receipt  of the  copies of the  supplemental  or  amended  prospectus
contemplated by this subsection, which the Company shall promptly make available
to each Holder and, if so directed by the Company,  each Holder shall deliver to
the Company all copies,  other than  permanent file copies then in such Holder's
possession,  of the prospectus  covering such Registrable  Securities current at
the time of receipt of such notice.

                           (iv)     Each Holder shall promptly  furnish to the
Company such  information  regarding
such  Holder and the  distribution  proposed  by such  Holder as the Company may
request in writing or as shall be required in connection with any  registration,
qualification  or  compliance  referred to in this  Section 8.1. The Holder will
promptly keep the Company  informed as to all sales of  Registerable  Securities
made under the  Registration  Statement  and assist the Company in updating such
information in the Registration Statement and any prospectus supplement relating
thereto.

                           (v)      (a) Each  Holder hereby  covenants with the
Company (1) not to make any sale of
the Shares  without  effectively  causing the prospectus  delivery  requirements
under the Securities Act to be satisfied,  and (2) if such Shares are to be sold
by  any  method  or in any  transaction  other  than  on a  national  securities
exchange, in the over-the-counter market, on the Nasdaq, in privately negotiated
transactions,  or in a  combination  of such  methods,  to notify the Company at
least five business  days prior to the date on which the Purchaser  first offers
to sell any such Shares.

                           (vi)     Each  Holder  acknowledges  and agrees  that
 the  Registrable  Securities  sold
pursuant  to the  registration  statement  described  in  this  Section  are not
transferable on the books of the Company unless the stock certificate  submitted
to the transfer  agent  evidencing  such Shares is  accompanied by a certificate
reasonably  satisfactory  to the Company to the effect that (A) the  Registrable
Securities have been sold in accordance with such registration statement and (B)
the requirement of delivering a current prospectus has been satisfied.

                                       17
<PAGE>

                           (vii)    Each Holder agrees that it will not effect
any  disposition of the  Registrable
Securities that would constitute a sale within the meaning of the Securities Act
except as contemplated in the registration statement referred to in this Section
8.1. Each Holder agrees not to take any action with respect to any  distribution
deemed to be made pursuant to such  registration  statement  that  constitutes a
violation of Regulation M under the Exchange Act or any other  applicable  rule,
regulation or law.

                  (g) Rule 144 Reporting. With a view to making available to the
Holders the benefits of certain  rules and  regulations  of the SEC which at any
time  permit  the  sale of the  Registrable  Securities  to the  public  without
registration, the Company agrees to use its reasonable best efforts to:

                           (i)      make and keep public information  available,
as those terms are understood and
defined in Rule 144 under the Securities Act, at all times;

                           (ii)     file with the SEC in a timely manner all
reports and other  documents  required
of the Company under the Exchange Act; and

                           (iii)    so long as a Holder owns any unregistered
Registrable  Securities,  furnish to
such Holder upon any reasonable request a written statement by the Company as to
its compliance  with Rule 144 under the Securities Act, and of the Exchange Act,
a copy of the most recent  annual or quarterly  report of the Company,  and such
other reports and documents of the Company as such Holder may reasonably request
in availing  itself of any rule or  regulation  of the SEC  allowing a Holder to
sell any such securities without registration.

                  (h) Transfer of Registration  Rights.  The rights to cause the
Company to register Registrable Securities granted to the Holders by the Company
under  subsection  8.1(a) may be assigned in full by a Holder to an Affiliate of
such Holder;  provided  that:  (i) such  transfer  may  otherwise be effected in
accordance with applicable securities laws; (ii) such Holder gives prior written
notice to the Company; and (iii) such transferee agrees to comply with the terms
and provisions of this Agreement including, without limitation, the restrictions
in Section 4.6 and such transfer is otherwise in compliance with this Agreement.
Except as  specifically  permitted by this paragraph (h), the rights of a Holder
with  respect  to  Registrable  Securities  as  set  out  herein  shall  not  be
transferable  to any other Person,  and any attempted  transfer  shall cause all
rights of such Holder therein to be forfeited.

                  (i) Waivers and  Amendments.  With the written  consent of the
Company  and  the  Holders  holding  at  least  a  majority  of the  Registrable
Securities (including Registrable Securities issuable pursuant to the Warrants),
any  provision  of this  Section  8.1 may be waived  (either  generally  or in a
particular  instance,  either  retroactively or  prospectively  and either for a
specified period of time or  indefinitely) or amended.  Upon the effectuation of
each such waiver or amendment,  the Company shall  promptly give written  notice
thereof to the Holders,  if any, who have not previously received notice thereof
or consented thereto in writing.

         8.2  Disposition.  The  Purchaser  has not and will not make any offer,
sale or other  transfer  of the Shares by any means  which would not comply with
applicable  law or this  Agreement  or which  would  otherwise  impose  upon the
Company any obligation to satisfy any public filing or registration requirement.
The  Purchaser  understands  and agrees  that any  disposition  of the Shares in
violation of this Agreement  shall be null and void, and that no transfer of the
Shares  shall be made by the Company or the  transfer  agent for the Shares upon
the Company's  stock  transfer  books or records unless and until there has been
compliance with the terms of this Agreement,  the Securities Act, any applicable
state and foreign securities law and any other laws. The Purchaser will not sell
or transfer the Shares unless:

                  (a) there is then in effect a registration statement under the
Securities Act covering such proposed  disposition and such  disposition is made
in accordance with such Registration Statement; or
18
<PAGE>

                  (b) it  shall  have  notified  the  Company  of  the  proposed
disposition  and shall have  furnished the Company with a detailed  statement of
the  circumstances  surrounding  the  proposed  disposition,  and it shall  have
furnished the Company with an opinion of counsel, reasonably satisfactory to the
Company that such  disposition is exempt from  registration of such shares under
the Securities Act or any applicable state, foreign or other securities laws.
The  Purchaser  will  not  transfer  the  Shares,  other  than  pursuant  to the
Registration  Statement or in a transaction  that complies with Rule 144, unless
the transferee makes the representations and warranties to the Company contained
in this  Agreement  and  agrees  to be bound  by the  restrictions  on  transfer
(including the registration  provisions)  contained herein to the same extent as
if it were the  original  Purchaser.  Without  limiting  the  generality  of any
provision  contained  herein,  at any time it owns Shares the Purchaser and each
transferee must and does agree that it and its respective Affiliates will comply
with all provisions of Section 4.6.

                                    SECTION 9

                                  Miscellaneous

         9.1 Termination of Agreement.  The Company may terminate its obligation
to perform or observe  any of its  covenants  and  agreements  hereunder  to any
Purchaser if such Purchaser  violates in a material  respect any of the material
covenants or agreements of the Purchaser under this  Agreement,  and a Purchaser
may  terminate  its  obligations  to perform or observe any of its covenants and
agreements hereunder if the Company violates or fails to perform in any material
respect any of the material  covenants or  agreements  of the Company under this
Agreement to such Purchaser; provided, however, that neither the Company nor the
Purchaser,  as the case may be, may terminate any of its obligations  under this
Agreement  pursuant  to this  sentence  unless it shall have  delivered  written
notice of such default to the other party and such  default  shall not have been
cured within 30 days after the delivery of such notice.

         9.2 GOVERNING LAW. THIS AGREEMENT  SHALL BE GOVERNED IN ALL RESPECTS BY
THE LAWS OF THE STATE OF NEW YORK AS APPLIED TO  CONTRACTS  ENTERED  INTO SOLELY
BETWEEN RESIDENTS OF, AND TO BE PERFORMED ENTIRELY WITHIN, SUCH STATE.

         9.3 Survival;  Reliance. The representations and warranties in Sections
3 and 4 of this Agreement shall survive any investigation made by the Purchasers
or the  Company  for a  period  of one  year  after  the  Closing  in  question.
Thereafter,  such  representations  and  warranties  shall  expire  and be of no
further force and effect,  and no cause of action may be brought with respect to
any breach thereof unless a written notice  specifying the nature and the amount
of the claims shall have been delivered by the Company or the Purchasers, as the
case may be, with respect thereto, on or before one year after the Closing Date.
Any representation or warranty contained herein may be relied upon by counsel to
the Company in  connection  with any opinion  delivered in  connection  with the
transactions contemplated hereby.

         9.4  Successors and Assigns.  This Agreement  shall be binding upon and
shall inure to the benefit of the parties hereto and their respective successors
and assigns,  provided,  however that the obligations of the Company pursuant to
Section  8.1 shall not  survive  (as  obligations  of the  Company  or any other
entity)  a merger  involving  the  Company,  in  which  the  Company  is not the
surviving  entity or following which the Company is a wholly owned subsidiary of
another entity.  Except as otherwise provided in this Agreement,  this Agreement
may not be assigned by a party  without the prior  written  consent of the other
party except by operation of law, in which case the assignee shall be subject to
all of the provisions of this Agreement.

         9.5 Notices and Dates.  Any notice or other  communication  given under
this Agreement shall be sufficient if in writing and will be effective as of (a)
the date of receipt if  delivered by hand,  by  messenger  or by courier,  or by
Federal Express or similar delivery service,  or transmitted by facsimile,  to a
party at its  address  set forth  below (or at such  other  address  as shall be
designated for such purpose by such party in a written notice to the other party
hereto) or (b) three days after the date when the same shall have been posted by
registered  mail,  return  receipt  requested,  in any post office in the United
States of America, postage prepaid and addressed to the party at such address:

                  (i)      if to the Company:

                           Edge Petroleum Corporation
                           1111 Bagby, Suite 2100
                           Houston, Texas 77002
                           Attn:  Chief Financial Officer
                           (Facsimile) (713) 654-7722

                 (ii)     if to Purchasers, then to the addresses set forth at
Exhibit A.

                  Each such notice or other communication shall for all purposes
of this Agreement be treated as effective or having been given when delivered if
delivered personally, by messenger or by courier, or, if sent by facsimile, upon
confirmation of receipt.

         9.6 Specific Performance. The parties hereto acknowledge and agree that
irreparable  damage  would  occur in the  event  any of the  provisions  of this
Agreement  were not  performed in  accordance  with its  specific  terms or were
otherwise  breached  and that  such  damage  would not be  compensable  in money
damages and that it would be extremely difficult or impracticable to measure the
resultant  damages.  It is  accordingly  agreed that any party  hereto  shall be
entitled to an injunction or injunctions  to prevent  breaches of the provisions
of this Agreement and to enforce  specifically the terms and provisions  hereof,
in addition to any other remedy to which it may be entitled at law or in equity,
and such party that is sued for breach of this  Agreement  expressly  waives any
defense  that a remedy in damages  would be adequate  and  expressly  waives any
requirement in an action for specific  performance  for the posting of a bond by
the party bringing such action.

         9.7  Further  Assurances.  The parties  hereto  shall do and perform or
cause to be done and  performed  all such  further  acts and  things  and  shall
execute and  deliver all such other  agreements,  certificates,  instruments  or
documents as any other party may  reasonably  request from time to time in order
to carry out the intent and purposes of this Agreement and the  consummation  of
the transactions contemplated hereby.

         9.8  Counterparts.  This  Agreement  may be  executed  in any number of
counterparts,  each of which may be executed  by fewer than all of the  parties,
each of which shall be enforceable  against the parties actually  executing such
counterparts, and all of which together shall constitute one instrument.

         9.9  Severability.  In the event that any  provision of this  Agreement
becomes or is  declared  by a court of  competent  jurisdiction  to be  illegal,
unenforceable  or void,  this Agreement  shall continue in full force and effect
without said provision; provided that no such severability shall be effective if
it materially changes the economic impact of this Agreement on any party.

         9.10 Captions.  Headings of the various sections of this Agreement have
been inserted for  convenience of reference only and shall not be relied upon in
construing this Agreement. Use of any gender herein to refer to any person shall
be deemed to  comprehend  masculine,  feminine  and neuter  unless  the  context
clearly requires otherwise.

         9.11 Public Statements. The Purchasers severally agree not to issue any
public  statement  with  respect  to  the  Purchasers'  investment  or  proposed
investment in the Company or the terms of any agreement or covenant between them
and the  Company  without  the  Company's  prior  written  consent,  except such
disclosures  as may be required  under  applicable  law or under any  applicable
order, rule or regulation.

                                       20

         9.12  Brokers.  Except as  otherwise  disclosed  by the  parties to one
another,  each  of the  Company  and the  Purchasers  severally  represents  and
warrants to the others that it has not engaged,  consented to or authorized  any
broker, finder or intermediary to act on its behalf, directly or indirectly,  as
a  broker,   finder  or  intermediary   in  connection  with  the   transactions
contemplated  by this Agreement.  Each of the Company and the Purchasers  hereby
severally  agrees to indemnify and hold harmless the others from and against all
fees,  commissions  or other payments owing to any such person or firm acting on
behalf of such Person hereunder.

         9.13 Costs and Expenses.  Each party hereto shall pay its own costs and
expenses  incurred in  connection  herewith,  including the fees of its counsel,
auditors and other representatives, whether or not the transactions contemplated
herein are consummated.

         9.14 No Third-Party  Rights.  Nothing in this Agreement shall create or
be deemed  to create  any  rights  in any  person or entity  not a party to this
Agreement except for such rights as may exist by virtue of any contract or other
agreement existing on the date hereof.

         9.15 Entire Agreement; Amendment. Except any confidentiality agreements
entered  into by the Company and any  Purchaser,  this  Agreement  and the other
documents delivered pursuant hereto (including the Warrant Agreement) constitute
the full and entire  understanding and agreement between the parties with regard
to the subject matter hereof and thereof and supersede all prior  agreements and
understandings among the parties relating to the subject matter hereof. No party
shall be  liable or bound to any other  party in any  manner by any  warranties,
representations  or covenants except as specifically  set forth herein.  Neither
this  Agreement  nor any term  hereof  may be  amended,  waived,  discharged  or
terminated other than by a written  instrument  signed by the party against whom
enforcement of any such amendment,  waiver,  discharge or termination is sought;
provided that any provision of this  Agreement,  other than Section 8.1 (waivers
and  amendments  of which are  governed  by  Section  8.1(i)),  may be waived or
modified on behalf of all of the Purchasers with the consent of those Purchasers
owning two-thirds of the Shares purchased  hereunder and that are still held (at
the time of such waiver or modification) by any Purchaser.

                                WARRANT AGREEMENT

                  THIS WARRANT AGREEMENT (the  "Agreement"),  dated as of May 6,
1999,  is made and  entered  into by and among  Edge  Petroleum  Corporation,  a
Delaware corporation (the "Company"),  and those persons set forth on Schedule 1
hereto    (collectively   the   "Warrantholders"   and   each   individually   a
"Warrantholder"). This Agreement is being executed in connection with the Common
Stock Subscription  Agreement of even date herewith by and among the Company and
the Warrantholders (the "Purchase Agreement").

                  The Company agrees to issue and sell,  and the  Warrantholders
agree to  severally  purchase,  for an agreed  value of $.125 per  warrant,  the
warrants,  as  hereinafter  described  (the  "Warrants"),  to  purchase up to an
aggregate of the number of shares set forth on Schedule 1 (the "Shares"), of the
Company's  Common  Stock,  par value $.01 per share (the  "Common  Stock").  The
purchase  and sale of the  Warrants  shall occur  contemporaneous  with,  and is
subject to the closing of the Purchase Agreement.

                  In  consideration  of the  foregoing  and for the  purpose  of
defining the terms and provisions of the Warrants and the respective  rights and
obligations thereunder, the Company and the Warrantholders,  for value received,
hereby agree as follows:

                  Section 1. Transferability and Form of Warrants.


                  1.1 Registration.  The Warrants shall be numbered and shall be
registered on the books of the Company when issued.

                  1.2 Limitations on Transfer. The Warrants and the Shares shall
not be sold,  assigned,  transferred  or  pledged  except  upon  the  conditions
specified  in  this  Agreement.  Each  Warrantholder  will  cause  any  proposed
purchaser, assignee, transferee or pledgee of the Warrants or the Shares, except
for  transferees  in  dispositions  of Shares that are  pursuant to an effective
registration statement under the Securities Act of 1933, as amended (the "Act"),
or  dispositions  of Common Stock (but  specifically  including  any transfer of
Warrants)  pursuant  to Rule 144 under  the Act,  to agree to take and hold such
securities  subject to the provisions and upon the conditions  specified in this
Agreement.  The Warrants may be divided or combined, upon request to the Company
by a Warrantholder, into a certificate or certificates representing the right to
purchase  the same  aggregate  number of Shares.  Unless the  context  indicates
otherwise,  the term "Warrantholder" shall include any transferee or transferees
of the Shares  that is required  to be bound by the terms  hereof,  and the term
"Warrants"  shall  include  any and all  warrants  outstanding  pursuant to this
Agreement,  including those  evidenced by a certificate or  certificates  issued
upon  division,  exchange  or  substitution  pursuant  to this  Agreement.  Each
Warrantholder by his receipt of a Warrant Certificate, agrees to be bound by and
comply  with the terms of this  Agreement.  Each  Warrantholder  represents  and
agrees that the Warrant  (and Shares if the Warrant is  exercised)  is purchased
only for  investment,  for such  Warrantholder's  own  account,  and without any
present  intention to sell,  or with a view to  distribution  of, the Warrant or
Shares.

                  1.3 Form of Warrants. The text of the Warrants and of the form
of election to purchase Shares shall be  substantially as set forth in Exhibit A
attached hereto.  The number of Shares issuable upon exercise of the Warrants is
subject to adjustment upon the occurrence of certain events,  all as hereinafter
provided.  The  Warrant  shall be  executed  on  behalf  of the  Company  by its
President or by a Vice  President,  attested to by its Secretary or an Assistant
Secretary.  A Warrant bearing the signature of an individual who was at any time
the proper officer of the Company shall bind the Company,  notwithstanding  that
such  individual  shall have ceased to hold such office prior to the delivery of
such Warrant or did not hold such office on the date of this Agreement.

                  The  Warrants  shall  be  dated  as of the  date of  signature
thereof by the Company either upon initial  issuance or upon division,  exchange
or substitution.

                  1.4 Legend on Warrants.  Each Warrant  Certificate  shall bear
the following legend:

                  (c)  Any  certificate  issued  at  any  time  in  exchange  or
substitution for any certificate bearing such legends (except in the case of the
Shares,  a new  certificate  issued  upon  completion  of a public  distribution
pursuant to a registration statement under the Act, or upon completion of a sale
under Rule 144 under the Act of the securities  represented  thereby) shall also
bear the above  legends  unless,  in the opinion of the Company's  counsel,  the
securities  represented  thereby need no longer be subject to such restrictions.
Each Warrantholder  consents to the Company making a notation on its records and
giving  instructions  to any registrar or transfer agent of the Warrants and the
Common Stock in order to implement the  restrictions on transfer  established in
this Agreement.

                  Section  2.  Exchange  of  Warrant  Certificate.  Any  Warrant
certificate may be exchanged for another certificate or certificates entitling a
Warrantholder  to purchase a like aggregate  number of Shares as the certificate
or certificates  surrendered then entitled such  Warrantholder to purchase.  Any
Warrantholder desiring to exchange a Warrant certificate shall make such request
in writing  delivered to the Company,  and shall surrender,  properly  endorsed,
with  signatures  guaranteed,  the  certificate  evidencing the Warrant to be so
exchanged.  Thereupon,  the  Company  shall  execute  and  deliver to the person
entitled thereto a new Warrant certificate as so requested.

                  Section 3. Term of Warrants; Exercise of Warrants; Redemption.

                  (a) Subject to the terms of this Agreement, each Warrantholder
shall  have the  right,  at any time and from  time to time  during  the  period
commencing  on the date of this  Agreement,  and ending at 5:00  p.m.,  Houston,
Texas Time,  on the fifth  anniversary  thereof  (the  "Termination  Date"),  to
purchase  from the  Company  up to the  number of fully  paid and  nonassessable
Shares to which  such  Warrantholder  may at the time be  entitled  to  purchase
pursuant to this  Agreement,  upon  surrender to the Company,  at its  principal
office,  of the  certificate  evidencing the Warrants to be exercised,  together
with the purchase  form on the reverse  thereof duly filled in and signed,  with
signatures guaranteed,  and upon payment to the Company of the Warrant Price (as
defined in and  determined in accordance  with the  provisions of this Section 3
and Sections 7 and 8 hereof),  for the number of Shares in respect of which such
Warrants  are then  exercised,  but in no event for less than 100 Shares for any
Warrantholder  (unless less than an aggregate of 100 Shares are then purchasable
under all outstanding Warrants held by a Warrantholder).

                  (b) Payment by each  Warrantholder  of the  aggregate  Warrant
Price  due from him  shall be made in cash or by  immediately  available  funds,
check or any combination thereof.

                  (c) Upon such  surrender  of the  Warrants and payment of such
Warrant Price as aforesaid, the Company shall issue and cause to be delivered to
or upon the written order of the  exercising  Warrantholder  and in such name or
names as the exercising Warrantholder may designate (which in no way shall limit
the transfer  restrictions  hereunder) a  certificate  or  certificates  for the
number of full Shares so purchased  upon the  exercise of his Warrant,  together
with cash, as provided in Section 9 hereof,  in respect of any fractional Shares
otherwise  issuable upon such surrender.  Such certificate or certificates shall
be deemed to have been issued and any person so  designated  to be named therein
shall be deemed to have become a holder of record of such  securities  as of the
date  of  surrender  of the  Warrants  and  payment  of the  Warrant  Price,  as
aforesaid,  notwithstanding  that the certificate or  certificates  representing
such  securities  shall  not  actually  have  been  delivered  or that the stock
transfer  books of the  Company  shall then be  closed.  The  Warrants  shall be
exercisable, at the election of a Warrantholder,  either in full or from time to
time in part and, in the event that a  certificate  evidencing  the  Warrants is
exercised  in respect of less than all of the  Shares  specified  therein at any
time prior to the Termination  Date, a new certificate  evidencing the remaining
portion  of the  Warrants  held by such  Warrantholder  will  be  issued  by the
Company.

                  (d)  The  Warrant  may  be  redeemed  at the  election  of the
Company,  as a whole but not in part, upon the terms and conditions set forth in
this Section 3(d).  The Company may call the Warrant for  redemption at any time
after such date (the "Redemption Event") at which the Trailing Price (as defined
herein) of the Common Stock exceeds  $10.70.  The price to be paid on redemption
shall be $.01 per  Share for which the  Warrant  is  exercisable,  appropriately
adjusted in the same manner as adjustments to the Warrant Price (the "Redemption
Price"). The Redemption Price shall be paid by the Company by check; however, if
the Company is  restricted  by law or agreement  from making such  payment,  the
Company  may  instead  make such  payment in shares of Common  Stock,  with such
Common  Stock  valued at the  Trailing  Price of the  Common  Stock on the fifth
business day prior to the date on which such payment is to be made.

                  (e) The  Company  shall  give  each  Warrantholder  notice  of
redemption  (in  accordance  with  Section  12  hereof)  mailed not less than 30
calendar  days  prior  to the  date  set  by the  Company  for  redemption  (the
"Redemption  Date").  Such notice shall state:  (i) the Redemption Date (ii) the
Redemption  Price (iii) the date on which a Redemption  Event  occurred and (iv)
the Trailing Price of the Common Stock on such date.

                  (f) The Warrant shall continue to be exercisable in accordance
with the terms and conditions  hereof until the Redemption  Date.  Following the
Redemption  Date, the Warrant shall no longer be  exercisable  and instead shall
represent only the right to receive the Redemption Price. If the Warrant has not
been exercised as of the Redemption  Date, the Company shall thereupon  promptly
transmit to each Warrantholder funds in the amount of the Redemption Price.

                  (g) For  purposes of this  Agreement,  the term the  "Trailing
Price" shall mean (i) in the case of a security  traded in the  over-the-counter
market and not in the Nasdaq  National  Market System  ("Nasdaq NMS") nor on any
national securities exchange, the average of the per share closing bid prices of
the Common Stock on the 20 consecutive  trading days  immediately  preceding the
date in  question,  as reported by Nasdaq or an  equivalent  generally  accepted
reporting service;  (ii) in the case of a security trade in the Nasdaq NMS or on
a national securities exchange,  the average for the 20 consecutive trading days
immediately preceding the date in question of the daily per share closing prices
of the Common  Stock in the Nasdaq NMS or on the  principal  stock  exchange  on
which it is listed,  as the case may be or (iii) if  neither  clause (i) or (ii)
above is applicable,  then the fair value thereof as determined in good faith by
the Company's  Board of Directors.  For purposes of clause (i) above, if trading
                                       3
<PAGE>

in the Common Stock is not reported by Nasdaq, the bid price referred to in said
clause shall be the lowest bid price as reported in the "pink sheets"  published
by National  Quotation  Bureau,  Incorporated.  The closing price referred to in
clause  (ii)  above  shall be the last  reported  sale price or, in case no such
reported  sale takes place on such day, the average of the reported  closing bid
and asked prices, in either case in the Nasdaq NMS or on the national securities
exchange on which the Common Stock is then listed.

                  Section  4.  Payment  of  Taxes.  The  Company  will  pay  all
documentary  stamp taxes, if any,  attributable  to the initial  issuance of the
Warrants or the securities comprising the Shares; provided, however, the Company
shall not be  required  to pay any tax which may be  payable  in  respect of any
secondary transfer of the Warrants or the securities comprising the Shares.

                  Section  5.  Mutilated  or  Missing  Warrants.   In  case  the
certificate or  certificates  evidencing the Warrants shall be mutilated,  lost,
stolen or destroyed, the Company shall, at the request of a Warrantholder, issue
and  deliver in  exchange  and  substitution  for and upon  cancellation  of the
mutilated  certificate or  certificates,  or in lieu of and substitution for the
certificate or certificates lost, stolen or destroyed, a new Warrant certificate
or certificates of like tenor and  representing an equivalent right or interest,
but only upon  receipt of  evidence  satisfactory  to the  Company of such loss,
theft or destruction of such Warrant and a bond of indemnity, if requested, also
satisfactory  in form and amount at the  applicant's  cost.  Applicants for such
substitute  Warrants  certificate  shall also comply with such other  reasonable
regulations and pay such other reasonable charges as the Company may prescribe.

                  Section 6. Reservation of Shares. There has been reserved, and
the  Company  shall at all times keep  reserved so long as the  Warrants  remain
outstanding, out of its authorized Common Stock, such number of shares of Common
Stock as shall be subject to purchase  under the Warrants.  Every transfer agent
for the Common  Stock and other  securities  of the  Company  issuable  upon the
exercise of the  Warrants  will be  irrevocably  authorized  and directed at all
times to reserve such number of authorized  shares and other securities as shall
be requisite for such purpose. The Company will keep a copy of this Agreement on
file with every transfer agent for the Common Stock and other  securities of the
Company  issuable  upon the  exercise of the  Warrants.  The Company will supply
every such transfer  agent with duly executed stock and other  certificates,  as
appropriate,  for such purpose and will provide or otherwise  make available any
cash which may be payable as provided in Section 9 hereof.  On or before  taking
any action that would cause an adjustment  pursuant to the terms of the Warrants
resulting  in an  increase in the number of shares of Common  Stock  deliverable
upon such conversion or exercise above the number thereof previously authorized,
reserved  and  available  therefor,  the  Company  shall take all such action so
required for compliance with this Section.

                  Section 7. Warrant Price.  The price per Share at which Shares
shall be  purchasable  upon the exercise of the Warrants (the  "Warrant  Price")
shall be as set forth in the Warrant subject to further  adjustment  pursuant to
Section 8 hereof.

                  Section 8. Adjustment of Number of Shares. The number and kind
of  securities  purchasable  upon the  exercise of the  Warrants and the Warrant
Price shall be subject to  adjustment  from time to time upon the  happening  of
certain events, as follows:

                  8.1  Adjustments.  The number of Shares  purchasable  upon the
exercise of the Warrants shall be subject to adjustment as follows:

                                        4
<PAGE>

                  (a) In case the  Company  shall (i) pay a  dividend  in Common
Stock or make a distribution  in Common Stock,  (ii)  subdivide its  outstanding
Common Stock,  (iii) combine its outstanding  Common Stock into a smaller number
of shares of Common Stock or (iv) issue by  reclassification of its Common Stock
other securities of the Company,  the number of Shares purchasable upon exercise
of  the  Warrants  immediately  prior  thereto  shall  be  adjusted  so  that  a
Warrantholder  shall be  entitled  to  receive  the kind and number of Shares or
other  securities  of the  Company  which it would have owned or would have been
entitled  to  receive  immediately  after  the  happening  of any of the  events
described  above  had the  Warrants  been  exercised  immediately  prior  to the
happening of such event or any record date with respect thereto.  Any adjustment
made pursuant to this subsection 8.1(a) shall become effective immediately after
the  effective  date of such event  retroactive  to the record date, if any, for
such event.

                  (b) In case the Company shall issue rights, options,  warrants
or  convertible  securities  to all or  substantially  all holders of its Common
Stock,  without any charge to such holders,  entitling  them to subscribe for or
purchase  Common  Stock at a price per share  which is lower at the record  date
mentioned  below than the then Fair Value (as  defined in Section 9), the number
of Shares  thereafter  purchasable  upon the exercise of each  Warrant  shall be
determined by  multiplying  the number of Shares  theretofore  purchasable  upon
exercise  of the  Warrant by a  fraction,  of which the  numerator  shall be the
number of shares of Common Stock  outstanding  immediately prior to the issuance
of such rights,  options,  warrants or convertible securities plus the number of
additional  shares of Common Stock offered for subscription or purchase,  and of
which the denominator  shall be the number of shares of Common Stock outstanding
immediately  prior  to  the  issuance  of  such  rights,  options,  warrants  or
convertible  securities  plus the number of shares which the aggregate  offering
price of the total number of shares  offered would  purchase at such Fair Value.
Such  adjustment  shall be made  whenever  such  rights,  options,  warrants  or
convertible  securities are issued,  and shall become effective  immediately and
retroactive to the record date for the determination of shareholders entitled to
receive such rights, options, warrants or convertible securities.

                  (c)  In  case  the  Company   shall   distribute   to  all  or
substantially  all holders of its Common Stock evidences of its  indebtedness or
assets  (excluding cash dividends or  distributions  out of earnings) or rights,
options,  warrants or convertible  securities  containing the right to subscribe
for or purchase Common Stock (excluding  those referred to in subsection  8.1(b)
above),  then in each case the number of Shares thereafter  purchasable upon the
exercise of the Warrants shall be determined by multiplying the number of Shares
theretofore  purchasable  upon exercise of the Warrants by a fraction,  of which
the  numerator  shall be the then Fair  Value  per share of Common  Stock on the
record date for such  distribution,  and of which the denominator  shall be such
Fair Value on such date  minus the then Fair Value of the  portion of the assets
or evidences of  indebtedness  so  distributed or of such  subscription  rights,
options,  warrants  or  convertible  securities  applicable  to one share.  Such
adjustment shall be made whenever any such distribution is made and shall become
effective  on the date of  distribution  retroactive  to the record date for the
determination of shareholders entitled to receive such distribution.

                  (d) No adjustment in the number of Shares purchasable pursuant
to the  Warrants  shall be required  unless  such  adjustment  would  require an
increase  or  decrease  of at least  three  percent in the number of Shares then
purchasable  upon the  exercise of the Warrants or, if the Warrants are not then
exercisable,  the number of Shares purchasable upon the exercise of the Warrants
on the first date  thereafter that the Warrants  become  exercisable;  provided,
however,  that any adjustments which by reason of this subsection 8.1(d) are not
required to be made immediately  shall be carried forward and taken into account
in any subsequent adjustment.

                  (e)  Whenever  the  number  of  Shares  purchasable  upon  the
exercise of the  Warrant is  adjusted,  as herein  provided,  the Warrant  Price
payable  upon  exercise of the Warrant  shall be  adjusted by  multiplying  such
Warrant Price immediately  prior to such adjustment by a fraction,  of which the
numerator  shall be the number of Shares  purchasable  upon the  exercise of the
Warrant immediately prior to such adjustment, and of which the denominator shall
be the number of Shares so purchasable immediately thereafter.

                                       5
<PAGE>

                  (f)  Whenever  the  number  of  Shares  purchasable  upon  the
exercise of the Warrants is adjusted as herein provided, the Company shall cause
to be  promptly  mailed  to each  Warrantholder  by first  class  mail,  postage
prepaid,  notice of such  adjustment  and a certificate  of the chief  financial
officer of the Company setting forth the number of Shares  purchasable  upon the
exercise of the Warrants after such  adjustment,  a brief statement of the facts
requiring such adjustment and the computation by which such adjustment was made.

                  (g) For the purpose of this  subsection  8.1, the term "Common
Stock" shall mean (i) the class of stock  designated  as the Common Stock of the
Company at the date of this  Agreement,  (ii) any other class of stock resulting
from  successive  change or  reclassifications  of such Common Stock  consisting
solely of changes in par  value,  or from par value to no par value,  or from no
par value to par value or (iii) if the Company merges or  consolidates  with, or
sells all or  substantially  all of its property and assets to,  another  Person
(other than a subsidiary  of the Company)  and  consideration  other than Common
Stock is payable to holders of Common  Stock in exchange  for their Common Stock
in connection with such merger,  consolidation or sale then "Common Stock" shall
thereafter  mean (and the Warrants  shall  thereafter be  exercisable  for) such
other consideration. In the event that at any time, as a result of an adjustment
made  pursuant  to this  Section 8, a  Warrantholder  shall  become  entitled to
purchase  any  securities  of the Company  other than Common  Stock,  (i) if the
Warrantholder's  right to purchase is on any other basis than that  available to
all holders of the Company's  Common Stock,  the Company shall obtain an opinion
of an independent  investment  banking firm or valuation firm valuing such other
securities  and  (ii)  thereafter  the  number  of  such  other   securities  so
purchasable  upon exercise of the Warrants  shall be subject to adjustment  from
time to time in a manner and on terms as nearly equivalent as practicable to the
provisions with respect to the Shares contained in this Section 8.

                  (h) Upon the  expiration of any rights,  options,  warrants or
conversion  privileges,  if such  shall not have been  exercised,  the number of
Shares  purchasable  upon exercise of Warrants,  to the extent the Warrants have
not then been exercised,  shall,  upon such expiration,  be readjusted and shall
thereafter be such as they would have been had they been originally adjusted (or
had the original adjustment not been required,  as the case may be) on the basis
of (i) the fact that  Common  Stock,  if any,  actually  issued or sold upon the
exercise of such rights,  options,  warrants or conversion privileges,  and (ii)
the fact that such shares of Common  Stock,  if any, were issued or sold for the
consideration  actually  received by the  Company  upon such  exercise  plus the
consideration,  if any, actually received by the Company for the issuance,  sale
or grant of all such rights, options,  warrants or conversion privileges whether
or not exercised;  provided,  however,  that no such readjustment shall have the
effect of  decreasing  the number of Shares  purchasable  upon  exercise  of the
Warrants by an amount in excess of the amount of the  adjustment  initially made
in respect of the issuance, sale or grant of such rights,  options,  warrants or
conversion privileges.

                  8.2 No Adjustment for Certain Matters.  During the term of the
Warrants or upon the exercise of the Warrants,  no adjustment  shall be made (i)
except  as  provided  in   subsection   8.1  in  respect  of  any  dividends  or
distributions  out of  earnings  or (ii) in respect of the  consummation  of any
action  described  in Section  10(b).  Without  limiting the  generality  of the
foregoing,  the  Company  shall have no  obligation  to cause any  purchaser  or
successor by merger,  sale of assets or similar  business  combination to assume
the obligations under this Agreement.

                  8.3 Par Value of Shares of Common  Stock.  Before  taking  any
action which would cause an adjustment  effectively  reducing the portion of the
Warrant Price  allocable to each Share below the then par value per share of the
Common Stock  issuable upon exercise of the Warrants,  the Company will take any
corporate action which may, in the opinion of its counsel, be necessary in order
that the Company may  validly  and  legally  issue fully paid and  nonassessable
Common Stock upon exercise of the Warrants.
                                       6
<PAGE>

                  8.4 Independent Public  Accountants.  The Company may retain a
firm of independent  public  accountants of recognized  national standing (which
may be any such firm regularly  employed by the Company) to make any computation
required  under this Section 8, and a  certificate  signed by such firm shall be
conclusive  evidence  of the  correctness  of any  computation  made  under this
Section 8.

                  8.5  Statement on Warrant  Certificates.  Irrespective  of any
adjustments  in the number of  securities  issuable  upon  exercise of Warrants,
Warrant  certificates  theretofore or thereafter  issued may continue to express
the same number of securities as are stated in the similar Warrant  certificates
initially issuable pursuant to this Agreement.  However, the Company may, at any
time in its sole discretion (which shall be conclusive),  make any change in the
form of  Warrant  certificate  that it may deem  appropriate  and that  does not
affect the substance  thereof;  and any Warrant  certificate  thereafter issued,
whether upon registration of, or in exchange or substitution for, an outstanding
Warrant certificate, may be in the form so changed

                  Section 9. Fractional Interests; Fair Value. The Company shall
not be required to issue fractional  Shares on the exercise of the Warrants.  If
any fraction of a Share would,  except for the  provisions of this Section 9, be
issuable on the exercise of the Warrants (or  specified  portion  thereof),  the
Company  shall pay an amount in cash  equal to the then Fair Value of the Common
Stock multiplied by such fraction.  As used herein, the term "Fair Value" of the
Common Stock or other  securities or other property shall mean the fair value as
determined   in  good  faith  by  the  Company's   Board  of  Directors,   which
determination shall be binding upon the Warrantholders;  provided, however, that
Fair  Value of the Common  Stock for any day shall  mean the last  sales  price,
regular way, on the day in question or, in case no such sale takes place on such
day, the average of the closing bid and asked prices,  regular way, on such day,
in either case as reported in the principal  transaction  reporting  system with
respect to securities  listed or admitted to trading on the  principal  national
securities exchange on which such security is listed or admitted to trading, or,
if such security is not listed or admitted to trading on any national securities
exchange but sales price information is reported for such security,  as reported
by the Nasdaq  NMS or such  other  self-regulatory  organization  or  registered
securities  information  processor (as such terms are used under the  Securities
Exchange  Act of 1934,  as  amended  (the  "Exchange  Act"))  that then  reports
information  concerning such security,  or, if sales price information is not so
reported,   the   average  of  the  high  bid  and  low  asked   prices  in  the
over-the-counter  market on such day,  as  reported  by Nasdaq NMS or such other
entity,  or, if on such day such security is not quoted by any such entity,  the
average of the  closing  bid and asked  prices as  furnished  by a  professional
market maker making a market in such security selected by the Board of Directors
of the  Company.  If on such  day no  market  maker is  making a market  in such
security,  the fair value of such  security  on such day as  determined  in good
faith by the Board of Directors of the Company shall be used.

                  Section 10. No Right as Stockholder; Notices to Warrantholder.
Nothing  contained in this  Agreement  or in the Warrants  shall be construed as
conferring upon any Warrantholder or its transferees any rights as a stockholder
of the Company,  including the right to vote, receive dividends,  call meetings,
consent  or  receive  notices as a  stockholder  in  respect  of any  meeting of
stockholders for the election of directors of the Company or any other matter or
imposing any fiduciary or other duty on the Company,  its officers or directors,
in  favor  of  any  Warrantholder,  all of  which  rights  and  duties  owed  to
stockholders are disclaimed and waived by each  Warrantholder.  If, however,  at
any time prior to the  expiration  of the Warrants and prior to their  exercise,
any one or more of the following events shall occur:

                                       7
<PAGE>

                  (a)      any  action  which  would  require  an  adjustment
pursuant  to  Section  8.1  (except subsections 8.1(e) and 8.1(g)); or

                  (b) a dissolution, liquidation or winding up of the Company or
a consolidation, merger or similar business combination or sale of its property,
assets and  business  as an entirety or  substantially  as an entirety  shall be
proposed;

then  the  Company   shall  give  notice  in  writing  of  such  event  to  each
Warrantholder,  as  provided  in Section 10 hereof,  promptly  prior to the date
fixed as a  record  date or the  date of  closing  the  transfer  books  for the
determination   of  the   stockholders   entitled  to  any  relevant   dividend,
distribution,  subscription  rights or other rights, or for the determination of
stockholders  entitled  to vote on such  proposed  dissolution,  liquidation  or
winding up. Such notice  shall  specify  such record date or the date of closing
the transfer  books,  as the case may be. Failure to mail or receive such notice
or any defect  therein  shall not affect the  validity of any action  taken with
respect thereto.

                  Section 11.  Securities Laws; Restrictions on Transfer of
Shares; Registration Rights.

                  11.1 Compliance with Securities Act. Each Warrantholder agrees
that this  Warrant  and the related  Shares  (each of the Warrant and the Shares
being referred to herein as a "Security" and together,  "Securities")  are being
acquired for investment and that such  Warrantholder  will not purchase,  offer,
sell or otherwise  dispose of any of the Securities  except under  circumstances
which will not  result in a  violation  of the Act.  In order to  exercise  this
Warrant,  a Warrantholder  must be able to confirm and shall confirm in writing,
by  executing  a  certificate  to  be  supplied  by  the  Company,  all  of  the
representations and other covenants contained in this Agreement,  including that
the  Securities so purchased are being  acquired for  investment  and not with a
view toward distribution or resale. The Shares (unless registered under the Act)
shall be stamped or  imprinted  with,  in addition to any other  appropriate  or
required legend, a legend in substantially the following form:

                  "THE  SECURITIES  EVIDENCED  HEREBY  HAVE NOT BEEN  REGISTERED
                  UNDER THE  SECURITIES  ACT OF 1933,  AS AMENDED,  OR ANY STATE
                  SECURITIES  LAWS.  NO  SALE  OR  DISPOSITION  MAY BE  EFFECTED
                  WITHOUT  (i)  AN  EFFECTIVE   REGISTRATION  STATEMENT  RELATED
                  THERETO, (ii) AN OPINION OF COUNSEL FOR THE HOLDER, REASONABLY
                  SATISFACTORY  TO THE COMPANY,  THAT SUCH  REGISTRATION  IS NOT
                  REQUIRED  AND ANY  PROSPECTUS  DELIVERY  REQUIREMENTS  ARE NOT
                  APPLICABLE  OR (iii)  RECEIPT OF  NO-ACTION  LETTERS  FROM THE
                  APPROPRIATE GOVERNMENTAL AUTHORITIES.  COPIES OF THE AGREEMENT
                  COVERING  THE  PURCHASE OF THESE  SECURITIES  AND  RESTRICTING
                  THEIR  TRANSFER MAY BE OBTAINED AT NO COST BY WRITTEN  REQUEST
                  MADE  BY THE  HOLDER  OF  RECORD  OF THIS  CERTIFICATE  TO THE
                  SECRETARY OF THE COMPANY AT THE PRINCIPAL EXECUTIVE OFFICES OF
                  THE COMPANY."

                  (a)   Warrantholder   Representations.   In   addition,   each
Warrantholder specifically represents to the Company both at the time of initial
purchase of the Warrant and at those future times as specified herein:

         (1) The  Warrantholder  has  experience  in analyzing  and investing in
companies  like the Company and is capable of evaluating the merits and risks of
an investment in the Company and has the capacity to protect its own  interests.
The  Warrantholder  is an "Accredited  Investor" as that term is defined in Rule
501(a)  promulgated  under the Act. The  Warrantholder is aware of the Company's
business affairs and financial condition, and has acquired information about the
Company  sufficient to reach an informed and  knowledgeable  decision to acquire
the  Securities.  The  Warrantholder  is acquiring  the  Securities  for its own
account for  investment  purposes  only not as a nominee or agent and not with a
view to, or for the resale in connection  with, any  "distribution"  thereof for
purposes  of  the  Act.  The  Warrantholder  is  acquiring  the  Securities  for
investment for its own account,  not as a nominee or agent,  and not with a view
to,  or  for  resale  in  connection   with,  any  distribution   thereof.   The
Warrantholder  acknowledges  the  Company's  obligation  to file a  registration
statement with respect to the Shares as set forth in the Purchase Agreement, the
effectiveness of which registration  statement may be required for the resale of
the  Shares.  The  Warrantholder  has not  offered  or sold any  portion  of the
Securities to be acquired by such  Warrantholder and has no present intention of
reselling  or  otherwise  disposing  of any  portion of such  Securities  either
currently or after the passage of a fixed or determinable period of time or upon
the occurrence or nonoccurrence of any predetermined event or circumstance,  and
in particular the  Warrantholder  has no current  intention to resell the Shares
                                       8
<PAGE>

under  such  registration  statement  nor would it have such  intention  if such
registration   statement  were  effective  as  of  the  date  of  purchase.  The
Warrantholder understands that investment in the Securities is subject to a high
degree of risk. The  Warrantholder can bear the economic risk of its investment,
including  the full loss of its  investment,  and by reason of its  business  or
financial experience or the business or financial experience of its professional
advisors has the capacity to evaluate the merits and risks of its investment and
protect its own interest in connection with the purchase of the  Securities.  If
other than an  individual,  the  Warrantholder  also  represents it has not been
organized for the purpose of acquiring the Securities.

         (2) The Warrantholder understands that the Securities have not been and
except as provided in the Purchase Agreement with respect to the Shares will not
be registered  under the Act or any applicable  State securities law in reliance
upon a specific exemption  therefrom,  which exemption depends upon, among other
things,  the bona fide nature of the  Warrantholder's  investment intent and the
accuracy of the  Warrantholder's  representations  as  expressed  herein and the
Warrantholder  will furnish the Company with such  additional  information as is
reasonably requested by the Company in connection with such exemption.

          (3) The Warrantholder  further understands that the Securities must be
held  indefinitely  unless  subsequently   registered  under  the  Act  and  any
applicable  state securities  laws, or unless  exemptions from  registration are
otherwise available. Moreover, the Warrantholder understands that the Company is
under no obligation to and does not expect to register the Securities  except as
provided for in the Purchase Agreement with respect to the Shares.

         4)  The   Warrantholder  is  aware  of  the  provisions  of  Rule  144,
promulgated under the Act, which, in substance,  permit limited public resale of
"restricted  securities"  acquired,  directly  or  indirectly,  from the  issuer
thereof (or from an Affiliate of such issuer),  in a nonpublic  offering subject
to the satisfaction of certain conditions, if applicable, including, among other
things:  The availability of certain public  information about the Company,  the
resale  occurring  not less than one year after the party has purchased and paid
for the  Securities  to be sold;  the sale  being  made  through  a broker in an
unsolicited  "broker's  transaction" or in  transactions  directly with a market
maker (as said term is defined  under the  Securities  Exchange Act of 1934,  as
amended) and the amount of securities  being sold during any three-month  period
not exceeding the specified limitations stated therein.

         (5) The Warrantholder  further understands that it may not transfer the
Warrants and that at the time it wishes to sell the  Securities,  it is possible
that there will be no public  market  upon which to make such a sale,  and that,
even if such a public market then exists,  the Company may not be satisfying the
current public  information  requirements  of Rule 144, and that, in such event,
the  Warrantholder  may be precluded from selling the Securities  under Rule 144
even if the one-year minimum holding period had been satisfied.

         (6) The Warrantholder  further understands that in the event all of the
requirements  of  Rule  144 are  not  satisfied,  registration  under  the  Act,
compliance   with   registration   exemption   will  be   required;   and  that,
notwithstanding  the fact  that  Rule  144 is not  exclusive,  the  Staff of the
Securities  and  Exchange  Commission  has  expressed  its opinion  that persons
proposing  to sell  private  placement  securities  other  than in a  registered
offering and otherwise than pursuant to Rule 144 will have a substantial  burden
of proof in  establishing  that an exemption from  registration is available for
such offers or sales,  and that such  persons and their  respective  brokers who
participate in such actions do so at their own risk.


                                       9

         (7) To the  Warrantholder's  knowledge,  the Warrantholder has received
copies of the Company's reports filed under the Exchange Act since the beginning
of the Company's  current  fiscal year. The  Warrantholder  has had a reasonable
opportunity  to ask questions  relating to and  otherwise  discuss the Company's
business,  management  and  financial  affairs  with the  Company's  management,
customers and other parties,  and the  Warrantholder  has received  satisfactory
responses to the  Warrantholder's  inquiries.  The  Warrantholder  disclaims and
disavows any reliance  upon Raymond James & Associates  Inc. in connection  with
the its purchase of Warrants.  The  Warrantholder  has relied  solely on its own
independent  investigation  before  deciding  to enter into the  purchase of the
Warrants  contemplated  hereby.  Unless the Warrantholder has otherwise notified
the Company in writing,  the  Warrantholder  is not, and has not been within the
ninety (90) days prior to the closing date of the purchase of the Securities,  a
broker  or  dealer  of  securities  an  officer,  director,  employee,  agent or
Affiliate  or the  Company,  or,  to the  Warrantholder's  knowledge,  any other
purchaser of Securities from the Company. Unless the Warrantholder has otherwise
notified the Company in writing,  the Warrantholder is not an employee,  officer
or  director  of the  Company  nor  prior  to the  consummation  of the  actions
contemplated  hereby, is the Warrantholder the beneficial owner of 5% or more of
the Common Stock of the Company.

                  (b) Disposition of Securities. With respect to any offer, sale
or other  disposition  of any Securities  that is not registered  under the Act,
each  Warrantholder  hereof  agrees to give written  notice to the Company prior
thereto,  describing briefly the manner thereof, together with a written opinion
of such Warrantholder's  counsel, if reasonably requested by the Company, to the
effect  that such  offer,  sale or other  disposition  may be  effected  without
registration or qualification (under the Act as then in effect or any federal or
state law then in effect) of such Securities and indicating whether or not under
the Act,  certificates  for the  Securities  in question to be sold or otherwise
disposed of require any  restrictive  legend as to  applicable  restrictions  on
transferability  in order to ensure  compliance with such law. Such opinion must
be satisfactory  to the Company in its reasonable  judgment and shall state that
it may be relied  upon by  counsel to the  Company,  and any stock  exchange  or
transfer  agent.  Promptly upon receiving  such written notice and  satisfactory
opinion, if so requested,  the Company shall notify such Warrantholder that such
Warrantholder may sell or otherwise dispose of such Securities all in accordance
with the terms of the notice  delivered to the Company.  If a determination  has
been made  pursuant to this  subsection  (b) that the opinion of counsel for the
Warrantholder  is not  satisfactory to the Company,  the Company shall so notify
such  Warrantholder  promptly after such  determination  has been made and shall
specify  in detail  the legal  analysis  supporting  any such  conclusion.  Each
certificate  representing  the Securities  thus  transferred  (except a transfer
registered  under  the  Act  or a  transfer  of  Shares  of  Common  Stock  (but
specifically including transfers of Warrants) pursuant to Rule 144) shall bear a
legend as to the applicable  restrictions on  transferability in order to ensure
compliance  with such laws,  unless in the aforesaid  opinion of counsel for the
Warrantholder,  such legend is not required in order to ensure  compliance  with
such laws.  The Company may issue stop  transfer  instructions  to its  transfer
agent in connection with such restrictions.

                  (c) Transferees Bound. Prior to any transfer of the Securities
(except a transfer  registered  under the Act or a transfer  of Shares of Common
Stock (but specifically  including transfers of Warrants) pursuant to Rule 144),
the proposed  transferee  shall agree in writing with the Company to be bound by
the terms of this  Agreement  (whether or not the Warrant has been  exercised or
otherwise  outstanding)  as if an  original  signatory  hereto and the  proposed
transferee  must be able to and must make  representations  as set forth in this
Section 11.1.

                  Section 11.2 Certain  Definitions. As used in this Section 11,
the  following  terms shall have the following meanings:

                  "Affiliate" shall mean, with respect to any person,  any other
person  controlling,  controlled by or under direct or indirect  common  control
with such person (for the purposes of this definition  "control," when used with
respect to any specified  person,  shall mean the power to direct the management
and policies of such person,  directly or indirectly,  whether through ownership
of voting securities,  by contract or otherwise; and the terms "controlling" and
"controlled" shall have meanings correlative to the foregoing).

                                       10

                  Section 12. Notices.  Any notice pursuant to this Agreement by
the Company or by a Warrantholder  or a holder of Shares shall be in writing and
shall be  deemed to have been duly  given if  delivered  or mailed by  certified
mail, return receipt requested:

                  (a) If to the Warrantholders or holders of Shares addressed to
them it at the address set forth in Schedule 1.

77002, Attention: Chief Financial Officer.

                  Each party may from time to time  change the  address to which
notices to it are to be  delivered or mailed  hereunder by notice in  accordance
herewith to the other party.

                  Section 13.  Successors.  All the covenants and  provisions of
this Agreement by or for the benefit of the Company,  the  Warrantholders or the
holders  of Shares  shall  bind and  inure to the  benefit  of their  respective
successors and assigns hereunder.

                  Section 14.  Applicable Law. This Agreement shall be deemed to
be a contract  made under the laws of the State of New York and for all purposes
shall be construed in accordance with the laws of said State.

                  Section  15.  Benefits  of  this  Agreement.  Nothing  in this
Agreement shall be construed to give to any person or corporation other than the
Company,  the  Warrantholders  and the holders of Shares any legal or  equitable
right,  remedy or claim under this  Agreement.  This Agreement  shall be for the
sole and exclusive benefit of the Company, the Warrantholders and the holders of
Shares.

                  Section 16.  Counterparts.  This Agreement  may be executed
in any number of  counterparts each of which shall be deemed an original, but
all of which shall constitute one and the same instrument.

                  Section 17.  Amendment.  Except as expressly  provided herein,
neither this Agreement nor any term hereof may be amended, waived, discharged or
terminated other than by a written  instrument  signed by the party against whom
enforcement of any such amendment,  waiver,  discharge or termination is sought;
provided, however, that any provisions hereof may be amended, waived, discharged
or  terminated  upon the written  consent of the  Company  and the then  current
Warrantholders  having the right to acquire by virtue of holding the Warrants at
least  50% of the  Shares  which are then  issuable  upon  exercise  of the then
outstanding Warrants.

                  IN WITNESS WHEREOF,  the parties have caused this Agreement to
be duly executed, all as of the day and year first above written.

                      ______________ SHARES OF COMMON STOCK

                           EDGE PETROLEUM CORPORATION

                           INCORPORATED UNDER THE LAWS
                            OF THE STATE OF DELAWARE

                  This certifies  that,  for value  received,  ___________,  the
registered  holder  hereof (the  "Warrantholder"),  is entitled to purchase from
EDGE  PETROLEUM  CORPORATION  (the  "Company"),  at any time  during  the period
commencing the date hereof and ending at 5:00 p.m., Houston,  Texas Time, on the
fifth anniversary  thereof at a purchase price per share of $5.35, the number of
shares of Common Stock of the Company set forth above (the "Shares"). The number
of shares of Common  Stock of the  Company  purchasable  upon  exercise  of each
Warrant evidenced hereby shall be subject to adjustment from time to time as set
forth in the  Warrant  Agreement.  The Warrant may be redeemed by the Company as
set forth in the Warrant Agreement.

                  The Warrants  evidenced hereby may be exercised in whole or in
part by presentation of this Warrant Certificate with the Purchase Form attached
hereto duly  executed  (with a signature  guarantee  as  provided  thereon)  and
simultaneous  payment  of the  Warrant  Price  at the  principal  office  of the
Company. Payment of such price shall be made in immediately available funds.

                  The Warrants  evidenced hereby represent the right to purchase
an aggregate of up to [__________] Shares and are issued under and in accordance
with a Warrant  Agreement,  dated as of May __, 1999 (the "Warrant  Agreement"),
between  the  Company  and  certain   Warrantholders  (which  Warrant  Agreement
initially  provides for Warrants to purchase up to  [_________]  shares) and are
subject to the terms and provisions  contained in the Warrant Agreement,  to all
of which the Warrantholder by acceptance hereof consents.

                  Upon any partial  exercise of the Warrants  evidenced  hereby,
there shall be signed and issued to the Warrantholder a new Warrant  Certificate
in respect of the Shares as to which the  Warrants  evidenced  hereby  shall not
have been  exercised.  These  Warrants  may be  exchanged  at the  office of the
Company by surrender of this Warrant  Certificate  properly  endorsed for one or
more new Warrants of the same  aggregate  number of Shares as here  evidenced by
the Warrant or Warrants exchanged.  No fractional shares of Common Stock will be
issued upon the exercise of rights to purchase hereunder,  but the Company shall
pay the cash value of any fraction  upon the  exercise of one or more  Warrants.
These Warrants are not transferrable and any attempted transfer shall be void.

                           EDGE PETROLEUM CORPORATION
                               1997 INCENTIVE PLAN

                                    STANDARD
                      NON-QUALIFIED STOCK OPTION AGREEMENT

                  THIS  AGREEMENT  ("Agreement")  is made as of the _____ day of
__________________,  ______ (the "Grant  Date"),  by and between Edge  Petroleum
Corporation, a Delaware corporation (the "Company"), and
 (the "Grantee").

                  The Company has adopted the Edge  Petroleum  Corporation  1997
Incentive  Plan (the "Plan"),  a copy of which is appended to this  Agreement as
Exhibit A and by this reference made a part hereof,  for the benefit of eligible
employees,  directors  and  independent  contractors  of  the  Company  and  its
Subsidiaries. Capitalized terms used and not otherwise defined herein shall have
the meaning ascribed thereto in the Plan.

                  Pursuant to the Plan, the Committee,  which has generally been
assigned responsibility for administering the Plan, has determined that it would
be in the  interest  of the Company  and its  stockholders  to grant the options
provided  herein in order to provide Grantee with  additional  remuneration  for
services  rendered,  to encourage Grantee to remain in the employ of the Company
or its Subsidiaries and to increase Grantee's personal interest in the continued
success and progress of the Company.

                  The Company and Grantee therefore agree as follows:

         1. Grant of Option.  Subject to the terms and  conditions  herein,  the
Company  grants to the  Grantee  during the period  commencing  on  ____________
_____,  ______ and expiring at 5 p.m. Houston,  Texas time ("Close of Business")
on  ____________  _____,   ______  (the  "Option  Term"),   subject  to  earlier
termination  pursuant  to  paragraph  6 below,  an option to  purchase  from the
Company,  at the price per share set forth on  Schedule  1 hereto  (the  "Option
Price"), the number of shares of Company Common Stock ("Common Stock") set forth
on said Schedule 1 (the "Option Shares"). The Option Price and Option Shares are
subject  to  adjustment  pursuant  to  paragraph  9 below.  This  option is as a
"Nonqualified Stock Option" and is hereinafter referred to as the "Option."

         2. Conditions of Exercise. The Option is exercisable only in accordance
with the conditions stated in this paragraph.

                  (a) Except as otherwise provided in this subparagraph (a), the
         Option may only be  exercised  to the extent  the  Option  Shares  have
         become   available  for  purchase  in  accordance  with  the  following
         schedule:

                                                Percentage of Option
                          Date                Shares Available for Purchase

                           ____________ _____, ______      20%
                           ____________ _____, ______      40%
                           ____________ _____, ______      60%
                           ____________ _____, ______      80%
                           ____________ _____, ______     100%

                                       1

         Notwithstanding  the  foregoing,  subject  to  the  provisions  of  any
         applicable  written  employment  agreement  between the Grantee and the
         Company or any  Subsidiary,  no  additional  Option Shares shall become
         available  for purchase if Grantee has not  remained in the  continuous
         employment of the Company and its  Subsidiaries  through the applicable
         date;  provided,  however,  that any Option Shares that would otherwise
         become available for purchase pursuant to the foregoing schedule during
         the  12-month  period  ending on the first  anniversary  of the date of
         Grantee's termination of employment shall become available for purchase
         on the specified  date during such period if the  Grantee's  employment
         was  terminated  for any reason  other  than (i) by the  Company or any
         Subsidiary   for  Cause  (as  defined  in  Section  6  below)  or  (ii)
         voluntarily by the Grantee without Good Reason (as defined in Section 6
         below).  A change of  employment is  continuous  employment  within the
         meaning of this paragraph 2 provided that,  after giving effect to such
         change,  the Grantee  continues to be an employee of the Company or any
         Subsidiary.

                  (b) To the extent the Option becomes exercisable,  such Option
         may be exercised in whole or in part (at any time or from time to time,
         except as otherwise  provided  herein)  until  expiration of the Option
         Term or earlier termination thereof.

         3. Manner of Exercise.  The Option shall be considered exercised (as to
the number of Option Shares  specified in the notice referred to in subparagraph
(a) below) on the latest of (i) the date of exercise  designated  in the written
notice referred to in subparagraph (a) below,  (ii) if the date so designated is
not a business  day,  the first  business day  following  such date or (iii) the
earliest business day by which the Company has received all of the following:

                  (a) Written notice, in such form as the Committee may require,
         designating, among other things, the date of exercise and the number of
         Option Shares to be purchased;

                  (b) If the  Option is to be  exercised,  payment of the Option
         Price for each Option Share to be purchased in cash, Common Stock or in
         such other form (or  combination of forms) of payment  contemplated  by
         Section 11 of the Plan as the Committee or the provisions of Section 11
         of the Plan may permit;  provided,  however,  that any shares of Common
         Stock  delivered  in payment  of the Option  Price that are or were the
         subject of an Employee  Award must be shares that the Grantee has owned
         for a period of at least six months prior to the date of exercise; and

                  (c) Any other  documentation that the Committee may reasonably
require.

         4. Mandatory  Withholding for Taxes.  Grantee  acknowledges  and agrees
that the  Company  shall  deduct  from the cash  and/or  shares of Common  Stock
otherwise  payable or deliverable  upon exercise of the Option an amount of cash
and/or  number of shares of Common  Stock  (valued at their Fair Market Value on
the date of  exercise)  that is equal to the  amount of all  federal,  state and
local  taxes  required to be withheld  by the  Company  upon such  exercise,  as
determined by the Committee.

         5. Delivery by the Company. As soon as practicable after receipt of all
items referred to in paragraph 3, and subject to the withholding  referred to in
paragraph 4, the Company  shall  deliver to the Grantee  certificates  issued in
Grantee's  name for the number of Option  Shares  purchased  by  exercise of the
Option.  If  delivery is by mail,  delivery  of shares of Common  Stock shall be
deemed  effected for all  purposes  when a stock  transfer  agent of the Company
shall have deposited the  certificates  in the United States mail,  addressed to
the Grantee, and any cash payment shall be deemed effected when a Company check,
payable to  Grantee  and in an amount  equal to the amount of the cash  payment,
shall have been deposited in the United States mail, addressed to the Grantee.

         6.  Termination  of  Employment.  Unless  otherwise  determined  by the
Committee  in its sole  discretion,  the Option  shall  terminate,  prior to the
expiration of the Option Term, at the time specified below:

                  (a) If Grantee terminates  employment with the Company and its
         Subsidiaries  voluntarily  without Good Reason (as defined below), then
         the  Option  shall  terminate  at the  Close of  Business  on the first
         business day following the  expiration of the 90-day period which began
         on the date of termination of Grantee's employment; or

                  (b)  If  Grantee's   employment   with  the  Company  and  its
         Subsidiaries is terminated by the Company or a Subsidiary for Cause (as
         defined below),  then the Option shall terminate  immediately upon such
         termination of Grantee's employment.

                  In any event in which the  Option  remains  exercisable  for a
period of time following the date of termination  of Grantee's  employment,  the
Option may be  exercised  during such period of time only to the extent it is or
becomes  exercisable as provided in paragraph 2.  Notwithstanding  any period of
time  referenced in this  paragraph 6 or any other  provision of this  paragraph
that may be construed to the contrary,  the Option shall in any event  terminate
upon the expiration of the Option Term.

                  "Cause"  for  purposes  of the  Agreement  shall mean cause as
defined in any written employment  agreement between the Grantee and the Company
or a Subsidiary in effect at the time of the Grantee's termination of employment
or, in the absence of any such employment agreement,  any of the following:  (a)
conviction of the Grantee by a court of competent  jurisdiction of any felony or
a crime involving moral turpitude;  (b) the Grantee's knowing failure or refusal
to follow reasonable instructions of the Board or reasonable policies, standards
and regulations of the Company or its Subsidiaries;  (c) the Grantee's continued
failure or refusal to faithfully  and  diligently  perform the usual,  customary
duties of his  employment  with the  Company or a  Subsidiary;  (d) the  Grantee
continuously  conducting  himself in an  unprofessional,  unethical,  immoral or
fraudulent  manner;  or (e) the Grantee's  conduct  discredits  the Company or a
Subsidiary or is  detrimental to the  reputation,  character and standing of the
Company or a Subsidiary.

                  "Good  Reason" for purposes of the  Agreement  shall mean good
reason as defined in any written  employment  agreement  between the Grantee and
the Company or a Subsidiary in effect at the time of the  Grantee's  termination
of  employment  or, in the absence of any such  employment  agreement,  shall be
deemed to have occurred upon the happening of any of the following:

                  (i)      any reduction in Grantee's annual rate of salary;

                  (ii) either (x) a failure of the Company to continue in effect
         any employee benefit plan in which Grantee was participating or (y) the
         taking  of any  action  by the  Company  that  would  adversely  affect
         Grantee's  participation  in, or materially  reduce Grantee's  benefits
         under,  any such  employee  benefit  plan,  unless such failure or such
         taking of any  action  adversely  affects  the  senior  members  of the
         corporate management of the Company generally;

                  (iii) the assignment to Grantee of duties and responsibilities
         that are materially  more oppressive or onerous than those attendant to
         Grantee's position immediately after the date hereof;

                  (iv) the  relocation  of the office  location  as  assigned to
         Grantee by the Company to a location more than 20 miles from  Grantee's
         current location without Grantee's consent; or

                                      3
<PAGE>

(v)  the  failure  of  the  Company  to  obtain,   prior  to  the  time  of  any
reorganization,  merger, consolidation,  disposition of all or substantially all
of the assets of the  Company or similar  transaction  effective  after the date
hereof,  in which the Company is not the  surviving  person,  the  unconditional
assumption  in writing or by operation of law of the  Company's  obligations  to
Grantee under this Agreement by each direct successor to the Company in any such
transaction.

         7.  Nontransferability of Option. During Grantee's lifetime, the Option
is not  transferable  (voluntarily  or  involuntarily)  other than pursuant to a
domestic  relations  order  and,  except as  otherwise  required  pursuant  to a
domestic  relations order, is exercisable only by the Grantee or Grantee's court
appointed  legal  representative.  The Grantee may  designate a  beneficiary  or
beneficiaries  to whom the Option shall pass upon Grantee's death and may change
such  designation  from  time  to  time  by  filing  a  written  designation  of
beneficiary  or  beneficiaries  with the Committee on the form annexed hereto as
Exhibit B or such other form as may be  prescribed  by the  Committee,  provided
that no such  designation  shall be effective unless so filed prior to the death
of Grantee. If no such designation is made or if the designated beneficiary does
not survive the  Grantee's  death,  the Option shall pass by will or the laws of
descent and  distribution.  Following  Grantee's death, the Option, if otherwise
exercisable,  may  be  exercised  by the  person  to  whom  such  option  passes
accordingly  to the  foregoing  and such person  shall be deemed the Grantee for
purposes of any applicable provisions of this Agreement.

         8. No  Stockholder  Rights.  The  Grantee  shall not be deemed  for any
purpose  to be, or to have any of the rights of, a  stockholder  of the  Company
with  respect to any shares of Common Stock as to which this  Agreement  relates
until such shares shall have been issued to Grantee by the Company. Furthermore,
the existence of this  Agreement  shall not affect in any way the right or power
of the Company or its  stockholders to accomplish any corporate act,  including,
without limitation, the acts referred to in Section 15 of the Plan.

         9.  Adjustments.  As  provided  in  Section  15 of  the  Plan,  certain
adjustments  may be  made  to the  Option  upon  the  occurrence  of  events  or
circumstances described in Section 15 of the Plan.

         10.  Restrictions  Imposed by Law.  Without  limiting the generality of
Section 16 of the Plan,  the Grantee  agrees that  Grantee will not exercise the
Option and that the  Company  will not be  obligated  to  deliver  any shares of
Common  Stock,  if counsel to the  Company  determines  that such  exercise,  or
delivery  would  violate any  applicable  law or any rule or  regulation  of any
governmental authority or any rule or regulation of, or agreement of the Company
with,  any  securities  exchange or  association  upon which the Common Stock is
listed  or  quoted.  The  Company  shall in no event  be  obligated  to take any
affirmative action in order to cause the exercise of the Option or the resulting
delivery of shares of Common Stock to comply with any such law, rule, regulation
or agreement.

         11.  Notice.  Unless the Company  notifies  the Grantee in writing of a
different  procedure,  any notice or other  communication  to the  Company  with
respect  to this  Agreement  shall be in  writing  and  shall  be (a)  delivered
personally to the following address:

shall be in writing and shall be delivered personally, or shall be sent by first
class mail,  postage prepaid,  to Grantee's  address as listed in the records of
the  Company  on the  Grant  Date,  unless  the  Company  has  received  written

         12.      Amendment.  Notwithstanding  any other provisions  hereof,
this Agreement may be supplemented or amended  from time to time as  approved
by the  Committee  as  contemplated  by  Section  6 of the  Plan.  Without
limiting the generality of the foregoing, without the consent of the Grantee,

                  (a) this Agreement may be amended or supplemented  (i) to cure
         any  ambiguity or to correct or supplement  any provision  herein which
         may be defective or inconsistent  with any other provision  herein,  or
         (ii) to add to the  covenants  and  agreements  of the  Company for the
         benefit of  Grantee  or  surrender  any right or power  reserved  to or
         conferred upon the Company in this Agreement,  subject, however, to any
         required approval of the Company's  stockholders and, provided, in each
         case, that such changes or corrections  shall not adversely  affect the
         rights of Grantee with respect to the Award  evidenced  hereby  without
         the  Grantee's  consent,  or (iii) to make such  other  changes  as the
         Company, upon advice of counsel,  determines are necessary or advisable
         because  of the  adoption  or  promulgation  of, or change in or of the
         interpretation   of,  any  law  or  governmental  rule  or  regulation,
         including any applicable federal or state securities laws; and

                  (b) subject to Section 6 of the Plan and any required approval
         of the Company's  stockholders,  the Award  evidenced by this Agreement
         may be canceled by the Committee  and a new Award made in  substitution
         therefor,  provided that the Award so substituted  shall satisfy all of
         the  requirements of the Plan as of the date such new Award is made and
         no such  action  shall  adversely  affect the Option to the extent then
         exercisable without the Grantee's consent.

         13. Grantee  Employment.  Nothing  contained in this Agreement,  and no
action of the Company or the Committee with respect  hereto,  shall confer or be
construed  to confer on the  Grantee  any right to continue in the employ of the
Company or any of its Subsidiaries or interfere in any way with the right of the
Company or any employing Subsidiary to terminate the Grantee's employment at any
time,  with  or  without  cause;  subject,  however,  to the  provisions  of any
employment agreement between the Grantee and the Company or any Subsidiary.

         14.  Governing Law. This Agreement  shall be governed by, and construed
in accordance with, the internal laws of the State of Delaware.

         15. Construction.  References in this Agreement to "this Agreement" and
the words "herein," "hereof," "hereunder" and similar terms include all Exhibits
and Schedules  appended  hereto,  including the Plan.  This Agreement is entered
into, and the Award evidenced hereby is granted,  pursuant to the Plan and shall
be governed by and construed in accordance with the Plan and the  administrative
interpretations  adopted  by the  Committee  thereunder.  All  decisions  of the
Committee  upon  questions  regarding  the  Plan  or  this  Agreement  shall  be
conclusive.  Unless  otherwise  expressly  stated  herein,  in the  event of any
inconsistency between the terms of the Plan and this Agreement, the terms of the
Plan shall  control.  The headings of the paragraphs of this Agreement have been
included for  convenience  of reference  only,  are not to be  considered a part
hereof and shall in no way  modify or  restrict  any of the terms or  provisions
hereof.

         16.  Duplicate  Originals.  The  Company  and the  Grantee may sign any
number of copies of this Agreement.  Each signed copy shall be an original,  but

                           EDGE PETROLEUM CORPORATION
                               1997 INCENTIVE PLAN

                        RESTRICTED STOCK AWARD AGREEMENT

                  THIS  AGREEMENT  ("Agreement")  is made as of the _____ day of
__________, _____ (the "Grant Date"), by and between Edge Petroleum Corporation,
a Delaware corporation (the "Company"), and ___________________ (the "Grantee").

                  The Company has adopted the Edge  Petroleum  Corporation  1997
Incentive  Plan (the "Plan"),  a copy of which is appended to this  Agreement as
Exhibit A and by this reference made a part hereof,  for the benefit of eligible
employees,  directors  and  independent  contractors  of  the  Company  and  its
Subsidiaries. Capitalized terms used and not otherwise defined herein shall have
the meaning ascribed thereto in the Plan.

                  Pursuant to the Plan, the Committee,  which has generally been
assigned responsibility for administering the Plan, has determined that it would
be in the interest of the Company and its  stockholders  to grant the restricted
stock  award  provided  herein  in  order to  provide  Grantee  with  additional
remuneration for services rendered, to encourage Grantee to remain in the employ
of the Company or its Subsidiaries and to increase  Grantee's  personal interest
in the continued success and progress of the Company.

                  The Company and Grantee therefore agree as follows:

                  1.  Grant of  Restricted  Stock.  In order  to  encourage  the
Grantee's  contribution  to the successful  performance  of the Company,  and in
consideration of the covenants and promises of the Grantee herein contained, the
Company hereby awards to the Grantee as of March 3, 1997 (the "Date of Grant") a
total of _______ shares of Common Stock  pursuant to the Plan,  upon the Date of
Grant,  subject to the  conditions and  restrictions  set forth below and in the
Plan ("Restricted Stock").

                  2.  Restrictions.  The  shares  of  Restricted  Stock  granted
hereunder  to the Grantee  may not be sold,  assigned,  transferred,  pledged or
otherwise  encumbered  from the Date of Grant  until the date  that the  Grantee
obtains a vested right to the shares (and the restrictions thereon terminate) in
accordance  with the  provisions  of this Section 2 or as otherwise  provided in
Section 6 below. (The period of time between the Date of Grant and the date that
the  Grantee  obtains  a vested  right to shares of  Restricted  Stock  shall be
referred to herein as the  "Restricted  Period" as to those shares of stock.) In
the event  that any day on which the  Grantee  would  otherwise  obtain a vested
right to additional shares of Restricted Stock is a Saturday, Sunday or holiday,
the Executive  shall instead  obtain that vested right on the first business day
immediately  following  such date.  The Grantee shall have a vested right to the
number of shares of Restricted  Stock  indicated below as of the dates set forth
below:

                Date              Number of Shares
                                    First Vested

                  All of the foregoing  provisions of this Section 2 are subject
to (A) the provisions of Section 6 below,  addressing  events that may result in
early  termination  of the  Restricted  Period or  forfeiture  of the  Grantee's
interest in all or part of the  Restricted  Shares and (B) the provisions of any
written employment agreement between the Grantee and the Company or a Subsidiary
that applies,  by its terms, to this Agreement and that is in effect at the time
its provisions would become operative with respect to this Agreement.

                  3. No Code Section 83(b) Election.  The Grantee shall not make
an election, under Code Section 83(b), to include an amount in income in respect
of Restricted Stock.

                  4. Sale of Restricted Stock. Grantee agrees that Grantee shall
not sell the  Restricted  Stock and that the Company  shall not be  obligated to
deliver  any shares of Common  Stock if counsel to the Company  determines  that
such sale or delivery would violate any applicable law or any rule or regulation
of any governmental  authority or any rule or regulation of, or agreement of the
Company with, any securities exchange or association upon which the Common Stock
is listed or quoted.  The  Company  shall in no event be  obligated  to take any
affirmative  action in order to cause the  delivery of shares of Common Stock to
comply with any such law, rule, regulation or agreement.

                  5. Escrow of Shares.  Shares of Restricted  Stock shall be, at
the election of the  Committee,  either (a)  registered in book entry form,  (b)
registered  in the name of the Grantee and  deposited  with the Secretary of the
Company or (c) held in nominee  name for the benefit of the  Grantee  during the
Restricted  Period, in any case, if the Company requests,  together with a stock
power endorsed by the Grantee in blank.  Any certificate  shall bear a legend as
provided by the Company,  conspicuously  referring to the terms,  conditions and
restrictions  described in the Plan and in this Agreement.  Upon  termination of
the Restricted Periods with respect to shares of Restricted Stock, a certificate
representing  such shares shall be delivered upon written request to the Grantee
as promptly as practicable following such termination.

                  6.       Accelerated Vesting of Restricted Stock; Forfeiture.

                  (a)  If  Grantee's   employment   with  the  Company  and  its
         Subsidiaries  (i) shall  terminate by reason of (x)  termination by the
         Company  without Cause (as defined  below),  (y) termination by Grantee
         for Good Reason (as defined below) or (z) Disability (as defined below)
         or (ii) if Grantee dies while  employed by the Company or a Subsidiary,
         then  the  Restricted  Periods  set  forth  in  Section  2 above  shall
         terminate and the Grantee's right to the Restricted  Stock shall become
         fully vested, to the extent not previously vested pursuant to Section 2
         above,  and   nonforfeitable,   and  all  restrictions   thereon  shall
         terminate.

                  (b)  If  Grantee's   employment   with  the  Company  and  its
         Subsidiaries  is terminated by the Company for Cause (as defined below)
         or  voluntarily  by the Grantee other than as provided in Section 6(a),
         then  all  Restricted  Stock  awarded  to  the  Grantee  that  has  not
         previously  vested in accordance with Sections 2 or 6(a) above shall be
         forfeited.

                  "Cause"  for  purposes  of the  Agreement  shall mean cause as
defined in any written employment  agreement between the Grantee and the Company
or a Subsidiary in effect at the time of the Grantee's termination of employment
or, in the absence of any such employment agreement,  any of the following:  (a)
conviction of the Grantee by a court of competent  jurisdiction of any felony or
a crime involving moral turpitude;  (b) the Grantee's knowing failure or refusal
to follow reasonable instructions of the Board or reasonable policies, standards
and regulations of the Company or its Subsidiaries;  (c) the Grantee's continued
failure or refusal to faithfully  and  diligently  perform the usual,  customary
duties of his  employment  with the  Company or a  Subsidiary;  (d) the  Grantee
continuously  conducting  himself in an  unprofessional,  unethical,  immoral or
fraudulent  manner;  or (e) the Grantee's  conduct  discredits  the Company or a
Subsidiary or is  detrimental to the  reputation,  character and standing of the
Company or a Subsidiary.

                  "Disability"   for  purposes  of  the  Agreement   shall  mean
disability as defined in any written  employment  agreement  between the Grantee
and  the  Company  or a  Subsidiary  in  effect  at the  time  of the  Grantee's
termination of employment or, in the absence of any such  employment  agreement,
as determined  by the  Committee in good faith and/or  pursuant to any long-term
disability plan sponsored by the Company or applicable Subsidiary.

                  "Good  Reason" for  purposes of the  Agreement  shall mean (a)
good reason as defined in any written  employment  agreement between the Grantee
and  the  Company  or a  Subsidiary  in  effect  at the  time  of the  Grantee's
termination of  employment,  (b) if such an agreement is then in effect and does
not define  "good  reason" but  contains a provision  permitting  the Grantee to
voluntarily  terminate  employment,  upon the occurrence of certain  events,  on
terms  substantially  equal to those  applicable to an  involuntary  termination
without  cause,  "Good  Reason"  shall  mean any of those  events  or (c) in the
absence of any such employment agreement definition or provision,  "Good Reason"
shall be deemed to have occurred upon the happening of any of the following:

                  (i)      any reduction in Grantee's annual rate of salary;

                  (ii) either (x) a failure of the Company to continue in effect
         any employee benefit plan in which Grantee was participating or (y) the
         taking  of any  action  by the  Company  that  would  adversely  affect
         Grantee's  participation  in, or materially  reduce Grantee's  benefits
         under,  any such  employee  benefit  plan,  unless such failure or such
         taking of any  action  adversely  affects  the  senior  members  of the
         corporate management of the Company generally;

                  (iii) the assignment to Grantee of duties and responsibilities
         that are materially  more oppressive or onerous than those attendant to
         Grantee's position immediately after the date hereof;

                  (iv) the  relocation  of the office  location  as  assigned to
         Grantee by the Company to a location more than 20 miles from  Grantee's
         current location without Grantee's consent; or

                  (v) the failure of the Company to obtain, prior to the time of
         any  reorganization,  merger,  consolidation,  disposition  of  all  or
         substantially  all of the assets of the Company or similar  transaction
         effective  after  the date  hereof,  in which  the  Company  is not the
         surviving  person,  the  unconditional  assumption  in  writing  or  by
         operation of law of the  Company's  obligations  to Grantee  under this
         Agreement  by  each  direct  successor  to  the  Company  in  any  such
         transaction.

                  All of the foregoing  provisions of this Section 6 are subject
to the provisions of any written  employment  agreement  between the Grantee and
the  Company  or a  Subsidiary  that is in effect  at the time of the  Grantee's
termination of employment and that applies, by its terms, to this Agreement.

                  7. Withholding for Taxes. Grantee acknowledges and agrees that
the Company may, at its option, deduct from the shares of Common Stock otherwise
payable or  deliverable  upon  expiration of the  Restricted  Period a number of
shares  of  Common  Stock  (valued  at their  Fair  Market  Value on the date of
exercise)  that is equal to the  amount of all  federal,  state and local  taxes
required to be withheld by the Company upon such exercise,  as determined by the
Committee.

                  8. Beneficiary  Designations.  The Grantee shall file with the
Secretary of the Company on the form  annexed  hereto as Exhibit B or such other
form  as  may be  prescribed  by  the  Company,  a  designation  of one or  more
beneficiaries  (each, a "Beneficiary")  to whom shares otherwise due the Grantee
shall be distributed in the event of the death of the Grantee while serving as a
Director  of the  Company.  The  Grantee  shall  have the  right to  change  the
Beneficiary or  Beneficiaries  from time to time;  provided,  however,  that any
change shall not become  effective until received in writing by the Secretary of
the Company. If any designated  Beneficiary survives the Grantee but dies before
receiving all of the Grantee's  benefits  hereunder,  any remaining benefits due
the Grantee shall be distributed to the deceased  Beneficiary's estate. If there
is no effective  Beneficiary  designation  on file at the time of the  Grantee's
death, or if the designated  Beneficiary or  Beneficiaries  have all predeceased
such  Grantee,  the  payment  of any  remaining  benefits  shall  be made to the
Grantee's estate.

                  9.  Nonalienation  of  Benefits.  Except  as  contemplated  by
Section 8 above,  and other than  pursuant  to a  qualified  domestic  relations
order,  no right or benefit under this  Agreement  shall be subject to transfer,
anticipation,  alienation,  sale,  assignment,  pledge,  encumbrance  or charge,
whether  voluntary,  involuntary  or by  operation  of law,  and any  attempt to
transfer,  anticipate,  alienate,  sell, assign, pledge,  encumber or charge the
same shall be void. No right or benefit  hereunder shall in any manner be liable
for or  subject  to any  debts,  contracts,  liabilities  or torts of the person
entitled to such benefits. If the Grantee or the Grantee's Beneficiary hereunder
shall become  bankrupt or attempt to  transfer,  anticipate,  alienate,  assign,
sell, pledge,  encumber or charge any right or benefit hereunder,  other than as
contemplated  by Section 8 above or other than pursuant to a qualified  domestic
relations  order, or if any creditor shall attempt to subject the same to a writ
of  garnishment,  attachment,  execution,  sequestration  or any  other  form of
process or involuntary  lien or seizure,  then such right or benefit shall cease
and terminate.

                  10.  Prerequisites to Benefits.  Neither the Grantee,  nor any
person  claiming  through  the  Grantee,  shall  have any right or  interest  in
Restricted Stock awarded hereunder,  unless and until all the terms,  conditions
and  provisions of this  Agreement and the Plan which affect the Grantee or such
other person shall have been complied with as specified herein.

                  11. Rights as a Stockholder.  Subject to the  limitations  and
restrictions  contained  herein,  the  Grantee (or  Beneficiary)  shall have all
rights as a stockholder with respect to the shares of Restricted Stock once such
shares have been  registered in the Grantee's  name or issued for the benefit of
Grantee hereunder.

                  12.  Adjustments.  As  provided  in  Section  15 of the  Plan,
certain  adjustments may be made to the Restricted  Stock upon the occurrence of
events or circumstances described in Section 15 of the Plan.

                  13. Notice. Unless the Company notifies the Grantee in writing
of a different procedure,  any notice or other communication to the Company with
respect to this Agreement shall be in writing and shall be:

shall be in writing and shall be delivered personally, or shall be sent by first
class mail,  postage prepaid,  to Grantee's  address as listed in the records of

limiting the generality of the foregoing, without the consent of the Grantee,

                  (a) this Agreement may be amended or supplemented  (i) to cure
         any  ambiguity or to correct or supplement  any provision  herein which
         may be defective or inconsistent  with any other provision  herein,  or
         (ii) to add to the  covenants  and  agreements  of the  Company for the
         benefit of  Grantee  or  surrender  any right or power  reserved  to or
         conferred upon the Company in this Agreement,  subject, however, to any
         required approval of the Company's  stockholders and, provided, in each
         case, that such changes or corrections  shall not adversely  affect the
         rights of Grantee with respect to the Award  evidenced  hereby  without
         the  Grantee's  consent,  or (iii) to make such  other  changes  as the
         Company, upon advice of counsel,  determines are necessary or advisable
         because  of the  adoption  or  promulgation  of, or change in or of the
         interpretation   of,  any  law  or  governmental  rule  or  regulation,
         including any applicable federal or state securities laws; and

                  (b) subject to Section 6 of the Plan and any required approval
         of the Company's  stockholders,  the Award  evidenced by this Agreement
         may be canceled by the Committee  and a new Award made in  substitution
         therefor,  provided that the Award so substituted  shall satisfy all of
         the requirements of the Plan as of the date such new Award is made.

                  15. Grantee  Employment.  Nothing contained in this Agreement,
and no action of the Company or the Committee with respect hereto,  shall confer
or be  construed to confer on the Grantee any right to continue in the employ of
the Company or any of its Subsidiaries or interfere in any way with the right of
the Company or any employing Subsidiary to terminate the Grantee's employment at
any time,  with or without  cause;  subject,  however,  to the provisions of any
employment agreement between the Grantee and the Company or any Subsidiary.

                  16.      Governing  Law. This Agreement  shall be governed by,

Agreement is entered into, and the Award evidenced  hereby is granted,  pursuant
to the Plan and shall be governed by and construed in  accordance  with the Plan
and the administrative  interpretations adopted by the Committee thereunder. All
decisions of the Committee upon  questions  regarding the Plan or this Agreement
shall be conclusive.  Unless otherwise  expressly stated herein, in the event of
any inconsistency between the terms of the Plan and this Agreement, the terms of
the Plan shall control. The headings of the Sections of this Agreement have been
included for  convenience  of reference  only,  are not to be  considered a part
hereof and shall in no way  modify or  restrict  any of the terms or  provisions
hereof.

                  18. Duplicate Originals.  The Company and the Grantee may sign

                           EDGE PETROLEUM CORPORATION
                               1997 INCENTIVE PLAN

                   DIRECTOR'S RESTRICTED STOCK AWARD AGREEMENT


                  THIS  AGREEMENT  ("Agreement")  is made as of the  ____ day of
_____________,  _______  (the "Date of Grant"),  by and between  Edge  Petroleum
Corporation,     a     Delaware     corporation     (the     "Company"),     and
___________________________ (the "Grantee").

                  The Company has adopted the Edge  Petroleum  Corporation  1997
Incentive  Plan (the "Plan"),  a copy of which is appended to this  Agreement as
Exhibit A and by this reference made a part hereof,  for the benefit of eligible
employees,  directors  and  independent  contractors  of  the  Company  and  its
Subsidiaries. Capitalized terms used and not otherwise defined herein shall have
the meaning ascribed thereto in the Plan. This Agreement documents the automatic
award made to the Grantee  pursuant  to Section  9(b) of the Plan on the Date of
Grant.

                  The Company and Grantee therefore agree as follows:

                  1.  Grant of  Restricted  Stock.  Effective  as of the Date of
Grant,  pursuant  to Section  9(b) of the Plan,  the  Company has awarded to the
Grantee a total of ______ shares of Common Stock,  subject to the conditions and
restrictions set forth below and in the Plan (the "Restricted Stock").

                  2.  Restrictions.  The  shares  of  Restricted  Stock  granted
hereunder  to the Grantee  may not be sold,  assigned,  transferred,  pledged or
otherwise  encumbered  from the Date of Grant  until the date  that the  Grantee
obtains a vested right to the shares (and the restrictions thereon terminate) in
accordance  with the  provisions  of this Section 2 or as otherwise  provided in
Section 6 below. (The period of time between the Date of Grant and the date that
the  Grantee  obtains  a vested  right to shares of  Restricted  Stock  shall be
referred to herein as the  "Restricted  Period" as to those shares of stock.) In
the event  that any day on which the  Grantee  would  otherwise  obtain a vested
right to additional shares of Restricted Stock is a Saturday, Sunday or holiday,
the Grantee  shall  instead  obtain that vested right on the first  business day
immediately  following  such date.  The Grantee shall have a vested right to the
number of shares of Restricted  Stock  indicated below as of the dates set forth
below, provided that the Grantee has been in continuous service as a Director of
the Company since the Date of Grant:


                Date                      Number of Shares
                                           First Vested

             ------------               -------------------------

             ------------               -------------------------

             ------------               -------------------------

All of the foregoing  provisions of this Section 2 are subject to the provisions
of  Section  6 below,  addressing  events  that  may  result  forfeiture  of the
Grantee's interest in all or part of the Restricted Shares.

                  3. No Code Section 83(b) Election.  The Grantee shall not make
an election, under Code Section 83(b), to include an amount in income in respect
of Restricted Stock.

                  4. Sale of Restricted Stock. Grantee agrees that Grantee shall
not sell the  Restricted  Stock and that the Company  shall not be  obligated to
deliver  any shares of Common  Stock if counsel to the Company  determines  that
such sale or delivery would violate any applicable law or any rule or regulation
of any governmental  authority or any rule or regulation of, or agreement of the
Company with, any securities exchange or association upon which the Common Stock
is listed or quoted.  The  Company  shall in no event be  obligated  to take any
affirmative  action in order to cause the  delivery of shares of Common Stock to
comply with any such law, rule, regulation or agreement.

                  5.  Escrow of  Shares.  Shares of  Restricted  Stock  shall be
registered  in the name of the Grantee and  deposited  with the Secretary of the
Company,  together  with a stock power  endorsed  by the  Grantee in blank.  Any
certificate  shall  bear a legend  as  provided  by the  Company,  conspicuously
referring to the terms, conditions and restrictions described in the Plan and in
this  Agreement.  Upon  termination  of the  Restricted  Periods with respect to
shares of  Restricted  Stock,  a certificate  representing  such shares shall be
delivered  upon  written  request to the  Grantee  as  promptly  as  practicable
following such termination.

                  6.  Forfeiture.  If  Grantee's  service  as a  Director  shall
terminate for any reason prior to all shares of  Restricted  Stock having become
vested pursuant to the provisions of Section 2 hereof, the Grantee shall forfeit
all right to those unvested shares of Restricted Stock unless otherwise  decided
by the Board.

                  7. Withholding for Taxes. Grantee acknowledges and agrees that
the Company may, at its option, deduct from the shares of Common Stock otherwise
payable or  deliverable  upon  expiration of the  Restricted  Period a number of
shares  of  Common  Stock  (valued  at their  Fair  Market  Value on the date of
exercise)  that is equal to the  amount of all  federal,  state and local  taxes
required  to be  withheld  by the  Company,  if  any,  upon  such  exercise,  as
determined by the Committee.

                  8. Beneficiary  Designations.  The Grantee shall file with the
Secretary of the Company on the form  annexed  hereto as Exhibit B or such other
form  as  may be  prescribed  by  the  Company,  a  designation  of one or  more
beneficiaries  (each, a "Beneficiary")  to whom shares otherwise due the Grantee
shall be distributed in the event of the death of the Grantee while serving as a
Director  of the  Company.  The  Grantee  shall  have the  right to  change  the
Beneficiary or  Beneficiaries  from time to time;  provided,  however,  that any
change shall not become  effective until received in writing by the Secretary of
the Company. If any designated  Beneficiary survives the Grantee but dies before
receiving all of the Grantee's  benefits  hereunder,  any remaining benefits due
the Grantee shall be distributed to the deceased  Beneficiary's estate. If there
is no effective  Beneficiary  designation  on file at the time of the  Grantee's
death, or if the designated  Beneficiary or  Beneficiaries  have all predeceased
such  Grantee,  the  payment  of any  remaining  benefits  shall  be made to the
Grantee's estate.

                  9.  Nonalienation  of  Benefits.  Except  as  contemplated  by
Section 8 above,  and other than  pursuant  to a  qualified  domestic  relations
order,  no right or benefit under this  Agreement  shall be subject to transfer,
anticipation,  alienation,  sale,  assignment,  pledge,  encumbrance  or charge,
whether  voluntary,  involuntary  or by  operation  of law,  and any  attempt to
transfer,  anticipate,  alienate,  sell, assign, pledge,  encumber or charge the
same shall be void. No right or benefit  hereunder shall in any manner be liable


                                       2
<PAGE>


for or  subject  to any  debts,  contracts,  liabilities  or torts of the person
entitled to such benefits. If the Grantee or the Grantee's Beneficiary hereunder
shall become  bankrupt or attempt to  transfer,  anticipate,  alienate,  assign,
sell, pledge,  encumber or charge any right or benefit hereunder,  other than as
contemplated  by Section 8 above or other than pursuant to a qualified  domestic
relations  order, or if any creditor shall attempt to subject the same to a writ
of  garnishment,  attachment,  execution,  sequestration  or any  other  form of
process or involuntary  lien or seizure,  then such right or benefit shall cease
and terminate.

                  10.  Prerequisites to Benefits.  Neither the Grantee,  nor any
person  claiming  through  the  Grantee,  shall  have any right or  interest  in
Restricted Stock awarded hereunder,  unless and until all the terms,  conditions
and  provisions of this  Agreement and the Plan which affect the Grantee or such
other person shall have been complied with as specified herein.

                  11. Rights as a Stockholder.  Subject to the  limitations  and
restrictions  contained  herein,  the  Grantee (or  Beneficiary)  shall have all
rights as a stockholder with respect to the shares of Restricted Stock once such
shares have been  registered in the Grantee's  name or issued for the benefit of
Grantee hereunder.

                  12.  Adjustments.  As  provided  in  Section  15 of the  Plan,
certain  adjustments may be made to the Restricted  Stock upon the occurrence of
events or circumstances described in Section 15 of the Plan.

                  13. Notice. Unless the Company notifies the Grantee in writing
of a different procedure,  any notice or other communication to the Company with
respect to this Agreement shall be in writing and shall be:

                      NON-QUALIFIED STOCK OPTION AGREEMENT


                  THIS  AGREEMENT  ("Agreement")  is  made  as of the 3rd day of
March,  1997 (the "Grant Date"),  by and between EDGE PETROLEUM  CORPORATION,  a
Delaware corporation (the "Company"), and JAMES D. CALAWAY (the "Grantee").

                  The Company has adopted the Edge  Petroleum  Corporation  1997
Incentive  Plan (the "Plan"),  a copy of which is appended to this  Agreement as
Exhibit A and by this reference made a part hereof,  for the benefit of eligible
employees,  directors  and  independent  contractors  of  the  Company  and  its
Subsidiaries. Capitalized terms used and not otherwise defined herein shall have
the meaning ascribed thereto in the Plan.

                  Pursuant to the Plan, the Committee,  which has generally been
assigned responsibility for administering the Plan, has determined that it would
be in the  interest  of the Company  and its  stockholders  to grant the options
provided  herein in order to provide Grantee with  additional  remuneration  for
services  rendered,  to encourage Grantee to remain in the employ of the Company
or its Subsidiaries and to increase Grantee's personal interest in the continued
success and progress of the Company.

                  The Company and Grantee therefore agree as follows:

         1. Grant of Option.  Subject to the terms and  conditions  herein,  the
Company grants to the Grantee during the period  commencing on March 3, 1997 and
expiring at 5 p.m.  Houston,  Texas time ("Close of  Business") on March 3, 2007
(the "Option Term"), subject to earlier termination pursuant to Section 6 below,
an  option to  purchase  from the  Company,  at the price per share set forth on
Schedule 1 hereto (the "Option  Price"),  the number of shares of Company Common
Stock ("Common Stock") set forth on said Schedule 1 (the "Option  Shares").  The
Option Price and Option Shares are subject to  adjustment  pursuant to Section 9
below.  This  option is as a  "Nonqualified  Stock  Option"  and is  hereinafter
referred to as the "Option".

         2. Conditions of Exercise. The Option is exercisable only in accordance
with the conditions stated in this Section.

                  (a) Except as otherwise  provided in this  Subsection (a), the
         Option may only be  exercised  to the extent  the  Option  Shares  have
         become   available  for  purchase  in  accordance  with  the  following
         schedule:
                                                   Percentage of Option
                               Date            Shares Available for Purchase
                           ------------        -----------------------------
                           March 3, 1998                  20%
                           March 3, 1999                  40%
                           March 3, 2000                  60%
                           March 3, 2001                  80%
                           March 3, 2002                 100%

         Notwithstanding the foregoing, all Option Shares shall become available
         for  purchase  if  Grantee's   employment  with  the  Company  and  its
         Subsidiaries  (i) shall  terminate by reason of (x)  termination by the
         Company without Cause (as defined in Section 6 below),  (y) termination
         by  Grantee  for Good  Reason  (as  defined  in Section 6 below) or (z)

                  (b) To the extent the Option becomes exercisable,  such Option
         may be exercised in whole or in part (at any time or from time to time,
         except as otherwise  provided  herein)  until  expiration of the Option
         Term or earlier termination thereof.

                  (c) All of the  foregoing  provisions  of this  Section  2 are
         subject to (i) the  provisions  of Section 6 below,  addressing  events
         that  may  result  in  early  termination  of the  Option  and (ii) the
         provisions of any written employment  agreement between the Grantee and
         the  Company  or a  Subsidiary  that  applies,  by its  terms,  to this
         Agreement and that is in effect at the time its provisions would become
         operative with respect to this Agreement.

         3. Manner of Exercise.  The Option shall be considered exercised (as to
the number of Option  Shares  specified in the notice  referred to in Subsection
(a) below) on the latest of (i) the date of exercise  designated  in the written
notice  referred to in Subsection  (a) below,  (ii) if the date so designated is
not a business  day,  the first  business day  following  such date or (iii) the
earliest business day by which the Company has received all of the following:

                  (a) Written notice, in such form as the Committee may require,
         designating, among other things, the date of exercise and the number of
         Option Shares to be purchased;

                  b) If the  Option is to be  exercised,  payment  of the Option
         Price for each Option Share to be purchased in cash, Common Stock or in
         such other form (or  combination of forms) of payment  contemplated  by
         Section 11 of the Plan as the Committee or the provisions of Section 11
         of the Plan may permit;  provided,  however,  that any shares of Common
         Stock  delivered  in payment  of the Option  Price that are or were the
         subject of an Employee  Award must be shares that the Grantee has owned
         for a period of at least six months prior to the date of exercise; and

                  (c)      Any other documentation that the Committee may
         reasonably require.

         4. Mandatory  Withholding for Taxes.  Grantee  acknowledges  and agrees
that the  Company  shall  deduct  from the cash  and/or  shares of Common  Stock
otherwise  payable or deliverable  upon exercise of the Option an amount of cash
and/or  number of shares of Common  Stock  (valued at their Fair Market Value on
the date of  exercise)  that is equal to the  amount of all  federal,  state and
local  taxes  required to be withheld  by the  Company  upon such  exercise,  as
determined by the Committee.

         5. Delivery by the Company. As soon as practicable after receipt of all
items  referred to in Section 3, and subject to the  withholding  referred to in
Section 4, the  Company  shall  deliver to the  Grantee  certificates  issued in
Grantee's  name for the number of Option  Shares  purchased  by  exercise of the
Option.  If  delivery is by mail,  delivery  of shares of Common  Stock shall be
deemed  effected for all  purposes  when a stock  transfer  agent of the Company
shall have deposited the  certificates  in the United States mail,  addressed to
the Grantee, and any cash payment shall be deemed effected when a Company check,
payable to  Grantee  and in an amount  equal to the amount of the cash  payment,
shall have been deposited in the United States mail, addressed to the Grantee.

         6.  Termination  of  Employment.  Unless  otherwise  determined  by the
Committee  in its sole  discretion,  the Option  shall  terminate,  prior to the
expiration of the Option Term, at the time specified below:


                                       2
<PAGE>

                 (a) If Grantee terminates  employment with the Company and its
         Subsidiaries  voluntarily  without Good Reason (as defined below), then
         the  Option  shall  terminate  at the  Close of  Business  on the first
         business day following the  expiration of the 90-day period which began
         on the date of termination of Grantee's employment; or

                  (b)  If  Grantee's   employment   with  the  Company  and  its
         Subsidiaries is terminated by the Company or a Subsidiary for Cause (as
         defined below),  then the Option shall terminate  immediately upon such
         termination of Grantee's employment.

                  In any event in which the  Option  remains  exercisable  for a
period of time following the date of termination  of Grantee's  employment,  the
Option may be  exercised  during  such  period of time only to the extent it was
exercisable  as provided in Section 2 on such date of  termination  of Grantee's
employment. A change of employment is not a termination of employment within the
meaning of this Section 6 provided that, after giving effect to such change, the
Grantee  continues  to  be  an  employee  of  the  Company  or  any  Subsidiary.
Notwithstanding  any period of time  referenced  in this  Section 6 or any other
provision of this Section  that may be  construed  to the  contrary,  the Option
shall in any event terminate upon the expiration of the Option Term.

                  "Cause"  for  purposes  of the  Agreement  shall mean cause as
defined in any written employment  agreement between the Grantee and the Company
or a Subsidiary in effect at the time of the Grantee's termination of employment
or, in the absence of any such employment agreement,  any of the following:  (a)
the Grantee is convicted of a felony involving moral turpitude,  (b) the Grantee
commits a willful  serious act intending to enrich himself at the expense of the
Company or any affiliated entity, or (c) the Grantee, in carrying out his duties
and  responsibilities  under  this  Agreement,  (i) is guilty of  willful  gross
neglect, or (ii) voluntarily engages in conduct that results in material harm to
the  Company or any  affiliated  entity,  unless  such  conduct  was  reasonably
believed  by the  Grantee  in good  faith  to be in the  best  interests  of the
Company.

                  "Disability"   for  purposes  of  the  Agreement   shall  mean
disability as defined in any written  employment  agreement  between the Grantee
and  the  Company  or a  Subsidiary  in  effect  at the  time  of the  Grantee's
termination of employment or, in the absence of any such  employment  agreement,
as determined  by the  Committee in good faith and/or  pursuant to any long-term
disability plan sponsored by the Company or applicable Subsidiary.

                  "Good  Reason" for  purposes of the  Agreement  shall mean (a)
good reason as defined in any written  employment  agreement between the Grantee
and  the  Company  or a  Subsidiary  in  effect  at the  time  of the  Grantee's
termination of  employment,  (b) if such an agreement is then in effect and does
not define  "good  reason" but  contains a provision  permitting  the Grantee to
voluntarily  terminate  employment,  upon the occurrence of certain  events,  on
terms  substantially  equal to those  applicable to an  involuntary  termination
without  cause,  "Good  Reason"  shall  mean any of those  events  or (c) in the
absence of any such employment agreement definition or provision,  "Good Reason"
shall be deemed to have occurred upon the happening of any of the following:

                  (i)      any reduction in Grantee's annual rate of salary;

                  (ii) either (x) a failure of the Company to continue in effect
         any employee benefit plan in which Grantee was participating or (y) the
         taking  of any  action  by the  Company  that  would  adversely  affect
         Grantee's  participation  in, or materially  reduce Grantee's  benefits
         under,  any such  employee  benefit  plan,  unless such failure or such
         taking of any  action  adversely  affects  the  senior  members  of the
         corporate management of the Company generally;

                                       3
<PAGE>

                  (iii) the assignment to Grantee of duties and responsibilities
         that are materially  more oppressive or onerous than those attendant to
         Grantee's position immediately after the date hereof;

                  (iv) the  relocation  of the office  location  as  assigned to
         Grantee by the Company to a location more than 20 miles from  Grantee's
         current location without Grantee's consent; or

                  (v) the failure of the Company to obtain, prior to the time of
         any  reorganization,  merger,  consolidation,  disposition  of  all  or
         substantially  all of the assets of the Company or similar  transaction
         effective  after  the date  hereof,  in which  the  Company  is not the
         surviving  person,  the  unconditional  assumption  in  writing  or  by
         operation of law of the  Company's  obligations  to Grantee  under this
         Agreement  by  each  direct  successor  to  the  Company  in  any  such
         transaction.

                  All of the foregoing  provisions of this Section 6 are subject
to the provisions of any written  employment  agreement  between the Grantee and
the  Company  or a  Subsidiary  that is in effect  at the time of the  Grantee's
termination of employment and that applies, by its terms, to this Agreement.

         7.  Nontransferability of Option. During Grantee's lifetime, the Option
is not  transferable  (voluntarily  or  involuntarily)  other than pursuant to a
domestic  relations  order  and,  except as  otherwise  required  pursuant  to a
domestic  relations order, is exercisable only by the Grantee or Grantee's court
appointed  legal  representative.  The Grantee may  designate a  beneficiary  or
beneficiaries  to whom the Option shall pass upon Grantee's death and may change
such  designation  from  time  to  time  by  filing  a  written  designation  of
beneficiary  or  beneficiaries  with the Committee on the form annexed hereto as
Exhibit B or such other form as may be  prescribed  by the  Committee,  provided
that no such  designation  shall be effective unless so filed prior to the death
of Grantee. If no such designation is made or if the designated beneficiary does
not survive the  Grantee's  death,  the Option shall pass by will or the laws of
descent and  distribution.  Following  Grantee's death, the Option, if otherwise
exercisable,  may  be  exercised  by the  person  to  whom  such  option  passes
accordingly  to the  foregoing  and such person  shall be deemed the Grantee for
purposes of any applicable provisions of this Agreement.

         8. No  Stockholder  Rights.  The  Grantee  shall not be deemed  for any
purpose  to be, or to have any of the rights of, a  stockholder  of the  Company
with  respect to any shares of Common Stock as to which this  Agreement  relates
until such shares shall have been issued to Grantee by the Company. Furthermore,
the existence of this  Agreement  shall not affect in any way the right or power
of the Company or its  stockholders to accomplish any corporate act,  including,
without limitation, the acts referred to in Section 15 of the Plan.

         9.  Adjustments.  As  provided  in  Section  15 of  the  Plan,  certain
adjustments  may be  made  to the  Option  upon  the  occurrence  of  events  or
circumstances described in Section 15 of the Plan.

         10.  Restrictions  Imposed by Law.  Without  limiting the generality of
Section 16 of the Plan,  the Grantee  agrees that  Grantee will not exercise the
Option and that the  Company  will not be  obligated  to  deliver  any shares of
Common  Stock,  if counsel to the  Company  determines  that such  exercise,  or
delivery  would  violate any  applicable  law or any rule or  regulation  of any
governmental authority or any rule or regulation of, or agreement of the Company
with,  any  securities  exchange or  association  upon which the Common Stock is
listed  or  quoted.  The  Company  shall in no event  be  obligated  to take any
affirmative action in order to cause the exercise of the Option or the resulting
delivery of shares of Common Stock to comply with any such law, rule, regulation
or agreement.

         12. Amendment.  Notwithstanding  any other provisions  hereof,  this
Agreement may be supplemented or amended  from time to time as  approved  by the
Committee  as  contemplated  by  Section  6 of the  Plan.  Without limiting the
generality of the foregoing, without the consent of the Grantee,

                  (a) this Agreement may be amended or supplemented  (i) to cure
         any  ambiguity or to correct or supplement  any provision  herein which
         may be defective or inconsistent  with any other provision  herein,  or
         (ii) to add to the  covenants  and  agreements  of the  Company for the
         benefit of  Grantee  or  surrender  any right or power  reserved  to or
         conferred upon the Company in this Agreement,  subject, however, to any
         required approval of the Company's  stockholders and, provided, in each
         case, that such changes or corrections  shall not adversely  affect the
         rights of Grantee with respect to the Award  evidenced  hereby  without
         the  Grantee's  consent,  or (iii) to make such  other  changes  as the
         Company, upon advice of counsel,  determines are necessary or advisable
         because  of the  adoption  or  promulgation  of, or change in or of the
         interpretation   of,  any  law  or  governmental  rule  or  regulation,
         including any applicable federal or state securities laws; and
                  (b) subject to Section 6 of the Plan and any required approval
         of the Company's  stockholders,  the Award  evidenced by this Agreement
         may be canceled by the Committee  and a new Award made in  substitution
         therefor,  provided that the Award so substituted  shall satisfy all of
         the  requirements of the Plan as of the date such new Award is made and
         no such  action  shall  adversely  affect the Option to the extent then
         exercisable without the Grantee's consent.

         13. Grantee  Employment.  Nothing  contained in this Agreement,  and no
action of the Company or the Committee with respect  hereto,  shall confer or be
construed  to confer on the  Grantee  any right to continue in the employ of the
Company or any of its Subsidiaries or interfere in any way with the right of the
Company or any employing Subsidiary to terminate the Grantee's employment at any
time,  with  or  without  cause;  subject,  however,  to the  provisions  of any
employment agreement between the Grantee and the Company or any Subsidiary.

         14.  Governing Law. This Agreement  shall be governed by, and construed
in accordance with, the internal laws of the State of Delaware.

                           EDGE PETROLEUM CORPORATION
                               1997 INCENTIVE PLAN

                        RESTRICTED STOCK AWARD AGREEMENT

                  THIS  AGREEMENT  ("Agreement")  is  made  as of the 3rd day of
March,  1997 (the "Grant Date"),  by and between Edge Petroleum  Corporation,  a
Delaware corporation (the "Company"), and James D. Calaway (the "Grantee").

                  The Company has adopted the Edge  Petroleum  Corporation  1997
Incentive  Plan (the "Plan"),  a copy of which is appended to this  Agreement as
Exhibit A and by this reference made a part hereof,  for the benefit of eligible
employees,  directors  and  independent  contractors  of  the  Company  and  its
Subsidiaries. Capitalized terms used and not otherwise defined herein shall have
the meaning ascribed thereto in the Plan.

                  Pursuant to the Plan, the Committee,  which has generally been
assigned responsibility for administering the Plan, has determined that it would
be in the interest of the Company and its  stockholders  to grant the restricted
stock  award  provided  herein  in  order to  provide  Grantee  with  additional
remuneration for services rendered, to encourage Grantee to remain in the employ
of the Company or its Subsidiaries and to increase  Grantee's  personal interest
in the continued success and progress of the Company.

                  The Company and Grantee therefore agree as follows:

                  1.  Grant of  Restricted  Stock.  In order  to  encourage  the
Grantee's  contribution  to the successful  performance  of the Company,  and in
consideration of the covenants and promises of the Grantee herein contained, the
Company  hereby  awards to the Grantee as of March 3, 1997 (the "Date of Grant")
(a) a total of 58,470 shares of Common Stock pursuant to the Plan, upon the Date
of Grant,  subject to the conditions and restrictions set forth below and in the
Plan  ("Scheduled  Stock"),  and (b) a total of 58,470  shares of Common  Stock,
pursuant  to the Plan,  upon the Date of Grant,  subject to the  conditions  and
restrictions  set  forth  below  and  in the  Plan  ("Performance  Stock")  (the
Scheduled Stock and the Performance Stock together, the "Restricted Stock").

                  2.  Restrictions.  The  shares  of  Restricted  Stock  granted
hereunder  to the Grantee  may not be sold,  assigned,  transferred,  pledged or
otherwise  encumbered  from the Date of Grant  until the date  that the  Grantee
obtains a vested right to the shares (and the restrictions thereon terminate) in
accordance  with the  provisions  of this Section 2 or as otherwise  provided in
Section 6 below. (The period of time between the Date of Grant and the date that
the  Grantee  obtains  a vested  right to shares of  Restricted  Stock  shall be

                  (b) Performance  Stock: As of March 3, 2007, the Grantee shall
         have a vested right to all 58,470 shares of  Performance  Stock awarded
         hereunder. Notwithstanding the foregoing, if any calendar year starting
         with 1997 and ending with 2006 is an  "Achieving  Year," as of the next
         January 1, the Grantee  shall have a vested right to (i) 11,694  shares
         of Performance  Stock for that Achieving Year and (ii) 11,694 shares of
         Performance Stock for each consecutive  "NonAchieving Year" immediately
         preceding the Achieving  Year;  provided,  however,  that the aggregate
         number of shares of  Performance  Stock to which the Grantee  obtains a
         vested right shall never exceed 58,470.

         For this purpose, the following definitions shall apply:

                  "Achieving  Year"  means a calendar  year for which the Actual
                  Price equals or exceeds the Target Price.

                  "Target Price" means (x) for 1997, $19.94  (representing a 25%
                  annual  increase over the Initial Public  Offering (IPO) price
                  of $16.50,  prorated to reflect the lapse of  approximately 10
                  months  between the IPO and December 31, 1997) and (y) for any
                  calendar year  subsequent to 1997,  125% of the greater of the
                  Target  Price for the  preceding  calendar  year or the Actual
                  Price for the preceding calendar year.

                  "Actual  Price"  means,  for any  calendar  year,  the  actual
                  average  closing  price per share of the Common  Stock for the
                  month of December.

                  "NonAchieving  Year" means a calendar  year from 1997  through
                   2006 that is notan Achieving Year.

                  All of the foregoing  provisions of this Section 2 are subject
to (A) the provisions of Section 6 below,  addressing  events that may result in
early  termination  of the  Restricted  Period or  forfeiture  of the  Grantee's
interest in all or part of the  Restricted  Shares and (B) the provisions of any
written employment agreement between the Grantee and the Company or a Subsidiary
that applies,  by its terms, to this Agreement and that is in effect at the time
its provisions would become operative with respect to this Agreement.

                  3. No Code Section 83(b) Election.  The Grantee shall not make
an election, under Code Section 83(b), to include an amount in income in respect
of Restricted Stock.

                  4. Sale of Restricted Stock. Grantee agrees that Grantee shall
not sell the  Restricted  Stock and that the Company  shall not be  obligated to
deliver  any shares of Common  Stock if counsel to the Company  determines  that
such sale or delivery would violate any applicable law or any rule or regulation
of any governmental  authority or any rule or regulation of, or agreement of the
Company with, any securities exchange or association upon which the Common Stock
is listed or quoted.  The  Company  shall in no event be  obligated  to take any
affirmative  action in order to cause the  delivery of shares of Common Stock to
comply with any such law, rule, regulation or agreement.

                  5. Escrow of Shares.  Shares of Restricted  Stock shall be, at
the election of the  Committee,  either (a)  registered in book entry form,  (b)
registered  in the name of the Grantee and  deposited  with the Secretary of the
Company or (c) held in nominee  name for the benefit of the  Grantee  during the
Restricted  Period, in any case, if the Company requests,  together with a stock
power endorsed by the Grantee in blank.  Any certificate  shall bear a legend as
provided by the Company,  conspicuously  referring to the terms,  conditions and
restrictions  described in the Plan and in this Agreement.  Upon  termination of
the Restricted Periods with respect to shares of Restricted Stock, a certificate
representing  such shares shall be delivered upon written request to the Grantee
as promptly as practicable following such termination.

                  6.       Accelerated Vesting of Restricted Stock; Forfeiture.

                or Death  (except  during a Window  Period).  If,  during the
         Employment Period, the Company shall terminate the Grantee's employment
         other than for Cause,  including a termination  by reason of Disability
         (but not by reason of death), or the Grantee shall terminate employment
         for Good Reason or his employment  shall be terminated  during a Window
         Period by the Company for Cause, by the Grantee without any reason,  or
         by reason of death,  effective as of the Date of Termination,  (1) each
         and every share of Restricted  Stock shall  immediately vest and become
         exercisable  and any  restrictions  on sale or transfer (other than any
         such restriction  arising by operation of law) shall terminate,  except
         that previously  unvested  shares of the  Performance  Stock shall vest
         only if termination  is by the Company  without Cause or by Grantee for
         Good Reason or in a Window Period and either (A) termination  occurs in
         the first year of the  Employment  Period in which  event the  unvested
         portion shall be 100% vested, (B) termination occurs in the second year
         of the  Employment  Period in which event 80% of the  unvested  portion
         shall be  vested,  (C)  termination  occurs  in the  third  year of the
         Employment  Period in which event 60% of the unvested  portion shall be
         vested or (D) termination occurs after the third year of the Employment
         Period  and the  performance  goals  have been met in each of the first
         three years of the Employment Period in which event all unvested shares
         shall be vested,  and (2) at the sole election of Grantee,  in exchange
         for any or all  Restricted  Stock,  the Company  shall pay an amount in
         cash equal to the Highest Price Per Share.

                  If the  Grantee's  employment is terminated by reason of the
         Grantee's  death during the  Employment  Period and other than during a
         Window  Period in which  event the  provisions  of  Section  6(a) shall
         govern,  effective  as of the Date of  Termination,  (1) each and every
         share of Restricted Stock shall immediately vest and become exercisable
         and  any  restrictions  on  sale  or  transfer  (other  than  any  such
         restriction  arising by operation of law) shall terminate,  except that
         previously  unvested shares of the Performance Stock shall vest only if
         either (A) death occurs in the first year of the  Employment  Period in
         which event the unvested portion shall be 100% vested, (B) death occurs
         in the second year of the  Employment  Period in which event 80% of the
         unvested portion shall be vested, (C) death occurs in the third year of

                                       3
<PAGE>

         the Employment  Period in which event 60% of the unvested portion shall
         be vested or (D) death  occurs  after the third year of the  Employment
         Period  and the  performance  goals  have been met in each of the first
         three years of the Employment Period in which event all unvested shares
         shall be vested,  and (2) at the sole election of the  Grantee's  legal
         representative,  in  exchange  for  any or all  Restricted  Stock,  the
         Company  shall  pay an amount in cash  equal to the  Highest  Price Per
         Share.

                  (c) Cause; Other than for Disability,  Good Reason or During a
         Window  Period.  If the Grantee's  employment  shall be terminated  for
         Cause  during the  Employment  Period  and other  than  during a Window
         Period, in which event the provisions of Section 6(a) shall govern, all
         Restricted Stock awarded to the Grantee that has not previously  vested
         in accordance with Sections 2 or 6(a) above shall be forfeited.  If the
         Grantee terminates employment during the Employment Period, excluding a
         termination  for any of  Disability,  Good Reason or without any reason
         during a Window  Period,  in which event the provisions of Section 6(a)
         shall govern,  all Restricted Stock awarded to the Grantee that has not
         previously  vested in accordance with Sections 2 or 6(a) above shall be
         forfeited.

                  Capitalized  terms  used  and not  otherwise  defined  in this
Section 6 shall have the meaning  ascribed  thereto in the Employment  Agreement
dated as of March 3,  1997 by and  between  the  Company  and the  Grantee  (the
"Employment  Agreement").  All of the foregoing provisions of this Section 6 are
subject to the provisions of the Employment Agreement.

                  7. Withholding for Taxes. Grantee acknowledges and agrees that
the Company may, at its option, deduct from the shares of Common Stock otherwise
payable or  deliverable  upon  expiration of the  Restricted  Period a number of
shares  of  Common  Stock  (valued  at their  Fair  Market  Value on the date of
exercise)  that is equal to the  amount of all  federal,  state and local  taxes
required to be withheld by the Company upon such exercise,  as determined by the
Committee.

                  8. Beneficiary  Designations.  The Grantee shall file with the
Secretary of the Company on the form  annexed  hereto as Exhibit B or such other
form  as  may be  prescribed  by  the  Company,  a  designation  of one or  more
beneficiaries  (each, a "Beneficiary")  to whom shares otherwise due the Grantee
shall be distributed in the event of the death of the Grantee while serving as a
Director  of the  Company.  The  Grantee  shall  have the  right to  change  the
Beneficiary or  Beneficiaries  from time to time;  provided,  however,  that any
change shall not become  effective until received in writing by the Secretary of
the Company. If any designated  Beneficiary survives the Grantee but dies before
receiving all of the Grantee's  benefits  hereunder,  any remaining benefits due
the Grantee shall be distributed to the deceased  Beneficiary's estate. If there
is no effective  Beneficiary  designation  on file at the time of the  Grantee's
death, or if the designated  Beneficiary or  Beneficiaries  have all predeceased
such  Grantee,  the  payment  of any  remaining  benefits  shall  be made to the
Grantee's estate.

                  9.  Nonalienation  of  Benefits.  Except  as  contemplated  by
Section 8 above,  and other than  pursuant  to a  qualified  domestic  relations
order,  no right or benefit under this  Agreement  shall be subject to transfer,
anticipation,  alienation,  sale,  assignment,  pledge,  encumbrance  or charge,
whether  voluntary,  involuntary  or by  operation  of law,  and any  attempt to
transfer,  anticipate,  alienate,  sell, assign, pledge,  encumber or charge the
same shall be void. No right or benefit  hereunder shall in any manner be liable
for or  subject  to any  debts,  contracts,  liabilities  or torts of the person
entitled to such benefits. If the Grantee or the Grantee's Beneficiary hereunder
shall become  bankrupt or attempt to  transfer,  anticipate,  alienate,  assign,
sell, pledge,  encumber or charge any right or benefit hereunder,  other than as
contemplated  by Section 8 above or other than pursuant to a qualified  domestic
relations  order, or if any creditor shall attempt to subject the same to a writ
of  garnishment,  attachment,  execution,  sequestration  or any  other  form of
process or involuntary  lien or seizure,  then such right or benefit shall cease
and terminate.

                  10.  Prerequisites to Benefits.  Neither the Grantee,  nor any
person  claiming  through  the  Grantee,  shall  have any right or  interest  in
Restricted Stock awarded hereunder,  unless and until all the terms,  conditions
and  provisions of this  Agreement and the Plan which affect the Grantee or such
other person shall have been complied with as specified herein.

                  11. Rights as a Stockholder.  Subject to the  limitations  and
restrictions  contained  herein,  the  Grantee (or  Beneficiary)  shall have all
rights as a stockholder with respect to the shares of Restricted Stock once such
shares have been  registered in the Grantee's  name or issued for the benefit of
Grantee hereunder.

                  12.  Adjustments.  As  provided  in  Section  15 of the  Plan,
certain  adjustments may be made to the Restricted  Stock upon the occurrence of
events or circumstances described in Section 15 of the Plan.

                  13. Notice. Unless the Company notifies the Grantee in writing

         the  Grantee's  consent,  or (iii) to make such  other  changes  as the
         Company, upon advice of counsel,  determines are necessary or advisable
         because  of the  adoption  or  promulgation  of, or change in or of the
         interpretation   of,  any  law  or  governmental  rule  or  regulation,
         including any applicable federal or state securities laws; and

                  (b) subject to Section 6 of the Plan and any required approval

         the requirements of the Plan as of the date such new Award is made.

                  15. Grantee  Employment.  Nothing contained in this Agreement,
and no action of the Company or the Committee with respect hereto,  shall confer
or be  construed to confer on the Grantee any right to continue in the employ of
the Company or any of its Subsidiaries or interfere in any way with the right of
the Company or any employing Subsidiary to terminate the Grantee's employment at
any time,  with or without  cause;  subject,  however,  to the provisions of any
employment agreement between the Grantee and the Company or any Subsidiary.

                  16.      Governing  Law. This Agreement  shall be governed by,

decisions of the Committee upon  questions  regarding the Plan or this Agreement
shall be conclusive.  Unless otherwise  expressly stated herein, in the event of
any inconsistency between the terms of the Plan and this Agreement, the terms of
the Plan shall control. The headings of the Sections of this Agreement have been
included for  convenience  of reference  only,  are not to be  considered a part
hereof and shall in no way  modify or  restrict  any of the terms or  provisions
hereof.

                  18. Duplicate Originals.  The Company and the Grantee may sign

                                         Grantee

                                                                   EXHIBIT 10.19


                           EDGE PETROLEUM CORPORATION
                               1997 INCENTIVE PLAN

                      NON-QUALIFIED STOCK OPTION AGREEMENT


                  THIS  AGREEMENT  ("Agreement")  is  made  as of the 3rd day of
March,  1997 (the "Grant Date"),  by and between EDGE PETROLEUM  CORPORATION,  a
Delaware corporation (the "Company"), and MICHAEL G. LONG (the "Grantee").

                  The Company has adopted the Edge  Petroleum  Corporation  1997
Incentive  Plan (the "Plan"),  a copy of which is appended to this  Agreement as
Exhibit A and by this reference made a part hereof,  for the benefit of eligible
employees,  directors  and  independent  contractors  of  the  Company  and  its
Subsidiaries. Capitalized terms used and not otherwise defined herein shall have
the meaning ascribed thereto in the Plan.

                  Pursuant to the Plan, the Committee,  which has generally been
assigned responsibility for administering the Plan, has determined that it would
be in the  interest  of the Company  and its  stockholders  to grant the options
provided  herein in order to provide Grantee with  additional  remuneration  for
services  rendered,  to encourage Grantee to remain in the employ of the Company
or its Subsidiaries and to increase Grantee's personal interest in the continued
success and progress of the Company.

                  The Company and Grantee therefore agree as follows:

         1. Grant of Option.  Subject to the terms and  conditions  herein,  the
Company grants to the Grantee during the period  commencing on March 3, 1997 and
expiring at 5 p.m.  Houston,  Texas time ("Close of  Business") on March 3, 2007
(the "Option Term"), subject to earlier termination pursuant to Section 6 below,
an  option to  purchase  from the  Company,  at the price per share set forth on
Schedule 1 hereto (the "Option  Price"),  the number of shares of Company Common
Stock ("Common Stock") set forth on said Schedule 1 (the "Option  Shares").  The
Option Price and Option Shares are subject to  adjustment  pursuant to Section 9
below.  This  option is as a  "Nonqualified  Stock  Option"  and is  hereinafter
referred to as the "Option."

         2. Conditions of Exercise. The Option is exercisable only in accordance
with the conditions stated in this Section.

                  (a) Except as otherwise  provided in this  Subsection (a), the
         Option may only be  exercised  to the extent  the  Option  Shares  have
         become   available  for  purchase  in  accordance  with  the  following
         schedule:

                                       1
<PAGE>

                                                      Perentage of Option
                                Date            Shares Available for Purchase

                           March 3, 1998                      20%
                           March 3, 1999                      40%
                           March 3, 2000                      60%
                           March 3, 2001                      80%
                           March 3, 2002                     100%

         Notwithstanding the foregoing, no additional Option Shares shall become
         available  for purchase if Grantee has not  remained in the  continuous
         employment of the Company and its  Subsidiaries  through the applicable
         date;  provided,  however,  that any Option Shares that would otherwise
         become available for purchase pursuant to the foregoing schedule during
         the  12-month  period  ending on the first  anniversary  of the date of
         Grantee's termination of employment shall become available for purchase
         on the specified  date during such period if the  Grantee's  employment
         was  terminated  for any reason  other  than (i) by the  Company or any
         Subsidiary   for  Cause  (as  defined  in  Section  6  below)  or  (ii)
         voluntarily by the Grantee without Good Reason (as defined in Section 6
         below).  A change of  employment is  continuous  employment  within the
         meaning of this Section 2 provided  that,  after giving  effect to such
         change,  the Grantee  continues to be an employee of the Company or any
         Subsidiary.

                  (b) To the extent the Option becomes exercisable,  such Option
         may be exercised in whole or in part (at any time or from time to time,
         except as otherwise  provided  herein)  until  expiration of the Option
         Term or earlier termination thereof.

                  (c) All of the  foregoing  provisions  of this  Section  2 are
         subject to (i) the  provisions  of Section 6 below,  addressing  events
         that  may  result  in  early  termination  of the  Option  and (ii) the
         provisions of any written employment  agreement between the Grantee and
         the  Company  or a  Subsidiary  that  applies,  by its  terms,  to this
         Agreement and that is in effect at the time its provisions would become
         operative with respect to this Agreement.

         3. Manner of Exercise.  The Option shall be considered exercised (as to
the number of Option  Shares  specified in the notice  referred to in Subsection
(a) below) on the latest of (i) the date of exercise  designated  in the written
notice  referred to in Subsection  (a) below,  (ii) if the date so designated is
not a business  day,  the first  business day  following  such date or (iii) the
earliest business day by which the Company has received all of the following:

                  (a) Written notice, in such form as the Committee may require,
         designating, among other things, the date of exercise and the number of
         Option Shares to be purchased;

                                       2
<PAGE>

                  (b) If the  Option is to be  exercised,  payment of the Option
         Price for each Option Share to be purchased in cash, Common Stock or in
         such other form (or  combination of forms) of payment  contemplated  by
         Section 11 of the Plan as the Committee or the provisions of Section 11
         of the Plan may permit;  provided,  however,  that any shares of Common
         Stock  delivered  in payment  of the Option  Price that are or were the
         subject of an Employee  Award must be shares that the Grantee has owned
         for a period of at least six months prior to the date of exercise; and

                  (c) Any other  documentation that the Committee may reasonably
require.

         4. Mandatory  Withholding for Taxes.  Grantee  acknowledges  and agrees
that the  Company  shall  deduct  from the cash  and/or  shares of Common  Stock
otherwise  payable or deliverable  upon exercise of the Option an amount of cash
and/or  number of shares of Common  Stock  (valued at their Fair Market Value on
the date of  exercise)  that is equal to the  amount of all  federal,  state and
local  taxes  required to be withheld  by the  Company  upon such  exercise,  as
determined by the Committee.

         5. Delivery by the Company. As soon as practicable after receipt of all
items  referred to in Section 3, and subject to the  withholding  referred to in
Section 4, the  Company  shall  deliver to the  Grantee  certificates  issued in
Grantee's  name for the number of Option  Shares  purchased  by  exercise of the
Option.  If  delivery is by mail,  delivery  of shares of Common  Stock shall be
deemed  effected for all  purposes  when a stock  transfer  agent of the Company
shall have deposited the  certificates  in the United States mail,  addressed to
the Grantee, and any cash payment shall be deemed effected when a Company check,
payable to  Grantee  and in an amount  equal to the amount of the cash  payment,
shall have been deposited in the United States mail, addressed to the Grantee.

         6.  Termination  of  Employment.  Unless  otherwise  determined  by the
Committee  in its sole  discretion,  the Option  shall  terminate,  prior to the
expiration of the Option Term, at the time specified below:

                  (a) If Grantee terminates  employment with the Company and its
         Subsidiaries  voluntarily  without Good Reason (as defined below), then
         the  Option  shall  terminate  at the  Close of  Business  on the first
         business day following the  expiration of the 90-day period which began
         on the date of termination of Grantee's employment; or

                  (b)  If  Grantee's   employment   with  the  Company  and  its
         Subsidiaries is terminated by the Company or a Subsidiary for Cause (as
         defined below),  then the Option shall terminate  immediately upon such
         termination of Grantee's employment.

                  In any event in which the  Option  remains  exercisable  for a
period of time following the date of termination  of Grantee's  employment,  the
Option may be  exercised  during  such  period of time only to the extent it was
exercisable  as provided in Section 2 on such date of  termination  of Grantee's
employment.  A change of employment is continuous  employment within the meaning
of this Section 6 provided that, after giving effect to such change, the Grantee
continues  to be an employee of the Company or any  Subsidiary.  Notwithstanding
any period of time  referenced in this Section 6 or any other  provision of this
Section  that may be construed  to the  contrary,  the Option shall in any event
terminate upon the expiration of the Option Term.

                                       3
<PAGE>

                  "Cause"  for  purposes  of the  Agreement  shall mean cause as
defined in any written employment  agreement between the Grantee and the Company
or a Subsidiary in effect at the time of the Grantee's termination of employment
or, in the absence of any such employment agreement,  any of the following:  (a)
the Grantee is convicted of a felony involving moral turpitude,  (b) the Grantee
commits a willful  serious act intending to enrich himself at the expense of the
Company or any affiliated entity, or (c) the Grantee, in carrying out his duties
and  responsibilities  under  this  Agreement,  (i) is guilty of  willful  gross
neglect, or (ii) voluntarily engages in conduct that results in material harm to
the  Company or any  affiliated  entity,  unless  such  conduct  was  reasonably
believed  by the  Grantee  in good  faith  to be in the  best  interests  of the
Company.

                  "Good  Reason" for  purposes of the  Agreement  shall mean (a)
good reason as defined in any written  employment  agreement between the Grantee
and  the  Company  or a  Subsidiary  in  effect  at the  time  of the  Grantee's
termination of  employment,  (b) if such an agreement is then in effect and does
not define  "good  reason" but  contains a provision  permitting  the Grantee to
voluntarily  terminate  employment,  upon the occurrence of certain  events,  on
terms  substantially  equal to those  applicable to an  involuntary  termination
without  cause,  "Good  Reason"  shall  mean any of those  events  or (c) in the
absence of any such employment agreement definition or provision,  "Good Reason"
shall be deemed to have occurred upon the happening of any of the following:

                  (i)      any reduction in Grantee's annual rate of salary;

                  (ii) either (x) a failure of the Company to continue in effect
         any employee benefit plan in which Grantee was participating or (y) the
         taking  of any  action  by the  Company  that  would  adversely  affect
         Grantee's  participation  in, or materially  reduce Grantee's  benefits
         under,  any such  employee  benefit  plan,  unless such failure or such
         taking of any  action  adversely  affects  the  senior  members  of the
         corporate management of the Company generally;

                  (iii) the assignment to Grantee of duties and responsibilities
         that are materially  more oppressive or onerous than those attendant to
         Grantee's position immediately after the date hereof;

                  (iv) the  relocation  of the office  location  as  assigned to
         Grantee by the Company to a location more than 20 miles from  Grantee's
         current location without Grantee's consent; or

                  (v) the failure of the Company to obtain, prior to the time of
         any  reorganization,  merger,  consolidation,  disposition  of  all  or
         substantially  all of the assets of the Company or similar  transaction
         effective  after  the date  hereof,  in which  the  Company  is not the
         surviving  person,  the  unconditional  assumption  in  writing  or  by
         operation of law of the  Company's  obligations  to Grantee  under this
         Agreement  by  each  direct  successor  to  the  Company  in  any  such
         transaction.

                  All of the foregoing  provisions of this Section 6 are subject
to the provisions of any written  employment  agreement  between the Grantee and
the  Company  or a  Subsidiary  that is in effect  at the time of the  Grantee's
termination of employment and that applies, by its terms, to this Agreement.

         7.  Nontransferability of Option. During Grantee's lifetime, the Option
is not  transferable  (voluntarily  or  involuntarily)  other than pursuant to a
domestic  relations  order  and,  except as  otherwise  required  pursuant  to a
domestic  relations order, is exercisable only by the Grantee or Grantee's court
appointed  legal  representative.  The Grantee may  designate a  beneficiary  or
beneficiaries  to whom the Option shall pass upon Grantee's death and may change
such  designation  from  time  to  time  by  filing  a  written  designation  of
beneficiary  or  beneficiaries  with the Committee on the form annexed hereto as
Exhibit B or such other form as may be  prescribed  by the  Committee,  provided
that no such  designation  shall be effective unless so filed prior to the death
of Grantee. If no such designation is made or if the designated beneficiary does
not survive the  Grantee's  death,  the Option shall pass by will or the laws of
descent and  distribution.  Following  Grantee's death, the Option, if otherwise
exercisable,  may  be  exercised  by the  person  to  whom  such  option  passes
accordingly  to the  foregoing  and such person  shall be deemed the Grantee for
purposes of any applicable provisions of this Agreement.

                                       4
<PAGE>

         8. No  Stockholder  Rights.  The  Grantee  shall not be deemed  for any
purpose  to be, or to have any of the rights of, a  stockholder  of the  Company
with  respect to any shares of Common Stock as to which this  Agreement  relates
until such shares shall have been issued to Grantee by the Company. Furthermore,
the existence of this  Agreement  shall not affect in any way the right or power
of the Company or its  stockholders to accomplish any corporate act,  including,
without limitation, the acts referred to in Section 15 of the Plan.

         9.  Adjustments.  As  provided  in  Section  15 of  the  Plan,  certain
adjustments  may be  made  to the  Option  upon  the  occurrence  of  events  or
circumstances described in Section 15 of the Plan.

         10.  Restrictions  Imposed by Law.  Without  limiting the generality of
Section 16 of the Plan,  the Grantee  agrees that  Grantee will not exercise the
Option and that the  Company  will not be  obligated  to  deliver  any shares of
Common  Stock,  if counsel to the  Company  determines  that such  exercise,  or
delivery  would  violate any  applicable  law or any rule or  regulation  of any
governmental authority or any rule or regulation of, or agreement of the Company
with,  any  securities  exchange or  association  upon which the Common Stock is
listed  or  quoted.  The  Company  shall in no event  be  obligated  to take any
affirmative action in order to cause the exercise of the Option or the resulting
delivery of shares of Common Stock to comply with any such law, rule, regulation
or agreement.

         11.  Notice.  Unless the Company  notifies  the Grantee in writing of a
different  procedure,  any notice or other  communication  to the  Company  with
respect  to this  Agreement  shall be in  writing  and  shall  be (a)  delivered
personally to the following address:

                                    Edge Petroleum Corporation

                                    1111 Bagby, Suite 2100
                                    Houston, Texas  77002

or (b) sent by first-class mail, postage prepaid and addressed as follows:

                                    Edge  Petroleum  Corporation  c/o  Corporate
                                    Secretary  Texaco Heritage Plaza 1111 Bagby,
                                    Suite 2100 Houston, Texas 77002.

Any notice or other  communication to the Grantee with respect to this Agreement
shall be in writing and shall be delivered personally, or shall be sent by first
class mail,  postage prepaid,  to Grantee's  address as listed in the records of
the  Company  on the  Grant  Date,  unless  the  Company  has  received  written
notification from the Grantee of a change of address.

         12.      Amendment.  Notwithstanding  any other provisions  hereof,
this Agreement may be supplemented or amended  from time to time as  approved
by the  Committee  as  contemplated  by  Section  6 of the  Plan.  Without
limiting the generality of the foregoing, without the consent of the Grantee,

                                       5
<PAGE>

                  (a) this Agreement may be amended or supplemented  (i) to cure
         any  ambiguity or to correct or supplement  any provision  herein which
         may be defective or inconsistent  with any other provision  herein,  or
         (ii) to add to the  covenants  and  agreements  of the  Company for the
         benefit of  Grantee  or  surrender  any right or power  reserved  to or
         conferred upon the Company in this Agreement,  subject, however, to any
         required approval of the Company's  stockholders and, provided, in each
         case, that such changes or corrections  shall not adversely  affect the
         rights of Grantee with respect to the Award  evidenced  hereby  without
         the  Grantee's  consent,  or (iii) to make such  other  changes  as the
         Company, upon advice of counsel,  determines are necessary or advisable
         because  of the  adoption  or  promulgation  of, or change in or of the
         interpretation   of,  any  law  or  governmental  rule  or  regulation,
         including any applicable federal or state securities laws; and

                  (b) subject to Section 6 of the Plan and any required approval
         of the Company's  stockholders,  the Award  evidenced by this Agreement
         may be canceled by the Committee  and a new Award made in  substitution
         therefor,  provided that the Award so substituted  shall satisfy all of
         the  requirements of the Plan as of the date such new Award is made and
         no such  action  shall  adversely  affect the Option to the extent then
         exercisable without the Grantee's consent.

         13. Grantee  Employment.  Nothing  contained in this Agreement,  and no
action of the Company or the Committee with respect  hereto,  shall confer or be
construed  to confer on the  Grantee  any right to continue in the employ of the
Company or any of its Subsidiaries or interfere in any way with the right of the
Company or any employing Subsidiary to terminate the Grantee's employment at any
time,  with  or  without  cause;  subject,  however,  to the  provisions  of any
employment agreement between the Grantee and the Company or any Subsidiary.

         14.  Governing Law. This Agreement  shall be governed by, and construed
in accordance with, the internal laws of the State of Delaware.

         15. Construction.  References in this Agreement to "this Agreement" and
the words "herein," "hereof," "hereunder" and similar terms include all Exhibits
and Schedules  appended  hereto,  including the Plan.  This Agreement is entered
into, and the Award evidenced hereby is granted,  pursuant to the Plan and shall
be governed by and construed in accordance with the Plan and the  administrative
interpretations  adopted  by the  Committee  thereunder.  All  decisions  of the
Committee  upon  questions  regarding  the  Plan  or  this  Agreement  shall  be
conclusive.  Unless  otherwise  expressly  stated  herein,  in the  event of any
inconsistency between the terms of the Plan and this Agreement, the terms of the
Plan shall  control.  The headings of the Sections of this  Agreement  have been
included for  convenience  of reference  only,  are not to be  considered a part
hereof and shall in no way  modify or  restrict  any of the terms or  provisions
hereof.

         16.  Duplicate  Originals.  The  Company  and the  Grantee may sign any
number of copies of this Agreement.  Each signed copy shall be an original,  but
all of them together represent the same agreement.

         17. Rules by Committee.  The rights of the Grantee and  obligations  of
the Company  hereunder shall be subject to such reasonable rules and regulations
as the Committee may adopt from time to time hereafter.

written  employment  agreement  between  the  Grantee  and  the  Company  or any
Subsidiary, Grantee and the Company hereby declare and represent that no promise
or agreement not herein expressed has been made and that this Agreement contains
