TRIANGLE BANCORP, INC.

                      1988 NON-QUALIFIED STOCK OPTION PLAN

     Triangle  Bancorp,  Inc. a bank holding company  existing under the laws of
the State of North Carolina (herein referred to as "Company"), hereby adopts the
following Non-Qualified Stock Option Plan (the "Plan") for the directors,  local
directors,  and other individuals  performing services for the Company or any of
its subsidiaries.

     1.  Purpose.  This Plan is intended to advance the interests of the Company
by allowing  directors,  local board  members,  officers,  and  employees of the
Company or any of its subsidiaries,  who have substantial responsibility for the
direction and management of the Company or any of its  subsidiaries to acquire a
proprietary  interest in the Company as an  additional  incentive to promote the
Company's  success,  and by encouraging  such individuals to continue to provide
their  services  to the Company or any of its  subsidiaries.  These aims will be
effectuated  by the  granting  of  certain  non-statutory,  non-qualified  stock
options.  Options  granted  under  this  Plan are  referred  to  hereinafter  as
"Options."

     2. Plan. The Plan shall be administered by the Compensation  Committee (the
"Committee") of the Board of Directors ("the Board") of the Company.  Subject to
the  provisions of the Plan,  the Committee  shall have full  authority,  in its
description,  to (a) determine the  individuals  (from the class of  individuals
eligible  under  Section 3 hereof  to  receive  Options  under the Plan) to whom
Options shall be granted; (b) determine the time or times at which Options shall
be granted; (c) determine the option price of the shares subject to each Option,
which price  shall be not less than the minimum  specified  in  accordance  with
Section 5 hereof; (d) determine (subject to Sections 7 and 9 hereof) the time or
times  when  each  Option  shall  become  exercisable  and the  duration  of the
exercise; and (e) interpret the Plan and prescribe, amend, and rescind rules and
regulations relating to it. The interpretation and construction of any provision
of the Plan by the Committee  shall be final and  conclusive.  The Committee may
consult  with  counsel and other  professional  advisors,  who may be counsel or
advisors to the Company,  and shall not incur any liability for any action taken
in good faith in reliance upon the advice of such counsel or advisors.

     3.  Eligibility.  (a) Options may be granted  only to members of the Board,
members of the boards of directors or local boards of directors,  or officers or
full-time  employees of the Company or any of its  subsidiaries.  In determining
the  eligibility of an individual to receive an Option as well as in determining
the number of shares to be  optioned  to any  individual,  the  Committee  shall
consider the position and  responsibilities  of the individual being considered,
the  nature  and  value  to  the  Company  of  such  individual's  services  and
accomplishments, the person's present and potential contributions to the success
of the Company and such other  factors as the  Committee  may deem  relevant.  A
person  receiving an Option pursuant to this Plan shall sometimes be referred to
hereinafter as an "Optionee."

     (b) Members of the Committee shall be entitled to receive Options under the
Plan to the same extent as other members of the Board.  However, any grant of an
Option to a member of the Committee must be approved by a disinterested majority
of the remaining members of the Committee;  such member must be excused from any
consideration  of a grant of such Option and shall not participate in any manner
in such decision.





     4. Shares of Stock Subject to the Plan. There will be reserved for use upon
the exercise of Options to be granted from time to time under the Plan  (subject
to the provisions of the provisions of Section 6 hereof) an aggregate of 388,002
as the Committee shall from time to time  determine,  may be in whole or in part
either  authorized but unissued  Shares,  or issued Shares which shall have been
reacquired by the Company. Any Shares subject to an Option under the Plan, which
Option for any reason  expires or is terminated  unexercised  as to such Shares,
may again be subjected to an Option under the Plan.

     5. Option  Price.  The  purchase  price under each Option  issued  shall be
determined by the  Committee at the time the Option is granted,  but in no event
shall  such  purchase  price be less then 100% of the fair  market  value of the
Company's  Shares on the date of the  grant.  If the  shares  are  traded in the
over-the-counter  market,  such fair market value shall be deemed to be the mean
between the asked and the bid prices on such day as  reported by NASDAQ.  If the
stock is traded on an exchange, such fair market value shall be deemed to be the
mean of the high and low prices at which it generally  has the greatest  trading
volume.  In all cases,  any  determination  hereunder by the Committee as to the
fair market value of the Shares for which  Options are granted  shall be made in
good faith and shall be determinative for all purposes of this Plan.

     6.  Adjustment  for  Dilution,  Etc.  In  the  event  that  there  is (a) a
subdivision or  consolidation of the Company's common stock or any other capital
adjustment  of the Company's  common stock,  (b) the payment by the Company of a
stock dividend,  or (c) any other increase or decrease in the outstanding common
stock of the Company  effected  without receipt of consideration by the Company,
then the  number of Shares  then  covered  by each  outstanding  Option  granted
hereunder  shall be adjusted  proportionately  with no  adjustment  in the total
purchase  price of the Shares then so covered by such Option,  and the number of
Shares  reserved  for the  purpose  of the Plan  shall be  adjusted  by the same
proportion.  All  such  adjustments  shall  be  made  by  the  Committee,  whose
determination  upon the same shall be final and binding upon the  Optionees.  No
fractional  Shares shall be issued and any fractional  Shares resulting from the
computation  pursuant to the Section 6 shall be eliminated  from the  respective
Option.  No  adjustment  shall be made for cash  dividends  or the  issuance  to
stockholders of rights to subscribe for additional Shares or other securities.

     7. Duration and Exercise of Options.  (a) All Options issued under the Plan
shall be for such period as the Board shall determine,  but for not more the ten
years from the date of the grant thereof.  The period of the Option,  once it is
granted, may be reduced only as outlined in Section 9 hereof; provided, however,
that  the   Committee   may,   where  the  Company  is  involved  in  a  merger,
consolidation,  dissolution, or liquidation,  accelerate the expiration date and
the dates on which any part of the Option may be exercisable  for all the Shares
covered thereby, but the effectiveness of such acceleration, and exercise of the
Option  pursuant  thereto  in excess of the  number of Shares for which it would
have been exercisable in the absence of such acceleration,  shall be conditioned
upon the consummation of the merger, consolidation, dissolution, or liquidation.
In no event may an Option be exercised after the expiration of its term.

     (b) Except as otherwise modified by the Committee or as otherwise expressly
provided  herein,  Options  granted under this Plan shall become  exercisable as
they vest in  accordance  with this Section 7. An Optionee  shall be entitled to
exercise the Option only as to the vested  portion of the Shares  subject to the
Option,  determined in accordance with and based on the whole number of years of
the  Optionee's  continued  service  with the Company or any  subsidiary  of the
Company in said capacity from the date the Option is

                                       2


granted  through  the  date of  termination  of  such  services,  determined  in
accordance with the following schedule:

                  Years of                 Vested Percentage
              Continued Service                of Shares
              -----------------                ---------

                     1                          33.33%
                     2                          33.33%
                     3                          33.33%

Any Shares not vested in accordance with the chart described  hereinabove  shall
be forfeited upon the termination of Optionee's  services for the Company or any
subsidiary  of the Company in one of the  capacities  indicated  in Section 3(a)
hereof,  and the  Optionee  shall have no right to  exercise  any  Options  with
respect thereto. In each such case, such limitations shall be calculated, in the
case of any resulting fraction,  to the nearest low whole number of Shares. Upon
the  termination of an Optionee's  services for the Company or any subsidiary of
the Company in one of the  capacities  indicated  in Section  3(a)  hereof,  any
vested  Option  or  Options  granted  to him  under  this  Plan  which  have not
previously  expired or been  exercised  shall be exercisable by the Optionee any
time within one year after such termination.

     (c) Subject to limitations  contained herein as to the time for exercise of
an Option and the amount of Shares subject to such Option,  and  notwithstanding
subsection (b) above, each Option shall be exercisable in whole or in part or in
installments  at such time or times  and in such  manner  as the  Committee  may
prescribe and specify in granting the Option to the  Optionee,  which manner may
differ from the exercise periods  otherwise  prescribed in subsection (b) above.
No Shares  shall be  delivered  pursuant to any  exercise of an Option until the
requirements  of such laws and  regulations as may be deemed by the Committee to
be  applicable  to them have been  satisfied,  and further  until receipt by the
Company of the full  option  price in cash for the Shares for which an Option is
exercised.

     (d) No Optionee or his legal representative,  legatees, or distributees, as
the case may be,  will  be,  or will be  deemed  to be, a holder  of any  Shares
subject to an Option unless and until certificates for such Shares are issued to
him or them under the terms of the plan. Except as otherwise provided herein, no
adjustment shall be made for dividends or other rights for which the record date
is prior to the date such stock certificate is issued.

     (e) (i) The exercise  price of the Shares subject to the Option may be paid
in cash or, at the  discretion  of the Board,  may also be paid by the tender of
Shares  already  owned by the  Optionee,  or through a  combination  of cash and
Shares,  or through such other means that the Board  determines  are  consistent
with the Plan's purpose and applicable law. No fractional  Shares will be issued
or accepted.

     (ii) The exercise price of the Shares subject to the Option may be paid, at
the discretion of the Board,  on a "cashless"  basis, by delivery to the Company
or its  designated  agent of an  irrevocable  written  notice of  exercise  form
together with  irrevocable  instructions to a broker-dealer  to sell or margin a
sufficient  portion of the shares of stock and  deliver  the sale or margin loan
proceeds directly to the Company to pay the exercise price.





     (iii) Receipt of Shares otherwise  issuable by the Company upon exercise of
an option by an  Optionee  may be  deferred  under a program of delayed  receipt
adopted  by  the  Board,  which  program  shall  contain  such  rules  governing
eligibility to participate,  timing of elections to defer, forms of distribution
of Shares and the like as the Board shall determine.

     8. Assignability. Each Option granted under this Plan shall be transferable
only  by will or by the  laws of the  descent  and  distribution  and  shall  be
exercisable,  during an  Optionee's  lifetime,  only by the Optionee to whom the
Option is granted.  Except as permitted  by the  preceding  sentence,  no Option
granted  under the Plan or any of the rights and  privileges  thereby  conferred
shall be transferred,  assigned, pledged, or hypothecated in any way (whether by
operation of law or otherwise), and no such Option, right, or privilege shall be
subject to execution,  attachment,  or similar  process.  Upon any attempt so to
transfer, assign, pledge, hypothecate, or otherwise dispose of the Option or any
right or privilege conferred thereby, contrary to the provisions hereof, or upon
the levy of any  attachment  or similar  process  upon such  Option,  right,  or
privilege,  the Option and such rights and privileges shall  immediately  become
null and void.

     9. Effect of Death or Disability. (a) Notwithstanding anything in this Plan
to the  contrary,  in the event an  Optionee's  services with the Company or any
subsidiary  of the Company in a capacity  described in Section 3(a) hereof shall
be terminated by reason of the Optionee's death or disability,  all Options held
by such Optionee which have not been theretofore  exercised or otherwise expired
shall be immediately exercisable in full, notwithstanding subsection 7(b) or (c)
hereof.

     (b) Upon the death or  disability  of an  Optionee,  any  Option or Options
granted  to him under  this  Plan  which  have not  previously  expired  or been
exercised  shall be  exercisable by the estate of the Optionee (or by any person
who acquired such Option by bequest or  inheritance  from the Optionee) in full,
notwithstanding  Section 7(b) or (c) hereof,  any time within one year after the
death of the  Optionee.  References  herein to the  Optionee  shall be deemed to
include  any person  entitled  to  exercise  the  Option  after the death of the
Optionee under the terms of this Section 9(b) . The term "disability" shall, for
the purposes of this Plan, be defined in the same manner as such term is defined
in Section 105(d)(4) of the Code.

     10. Listing and Registration of Shares. Each Option shall be subject to the
requirement  that  if  at  any  time  the  Committee  shall  determine,  in  its
discretion,  that the  listing,  registration,  or  qualification  of the  Share
covered thereby upon any securities exchange or any state or federal law, or the
consent or  approval  of any  governmental  regulatory  body,  is  necessary  or
desirable as a condition of, or in connection  with, the granting of such Option
or the issue or purchase of Shares thereunder,  such Option may not be exercised
in whole or in part unless and until such listing, registration,  qualification,
consent, or approval shall have been effected or obtained free of any conditions
not acceptable to the  Committee.  The Company shall not be required to issue or
deliver any  certificate  for Shares of its stock purchased upon the exercise of
any part of an Option  before (i) the admission of such Shares to listing on any
stock  exchange  in which  the stock of the  Company  may then be  listed,  (ii)
completion of any  registration or other  qualification of such Shares under any
state or federal law or ruling or regulation of any governmental regulatory body
that the  Committee  shall,  in its sole  discretion,  determine is necessary or
advisable,  and (iii) the Committee  shall have been advised by counsel that all
applicable legal requirements have been complied with and satisfied.

     11.  Expiration and  Termination of the Plan.  Options may be granted under
the Plan at any time or from time to time so long as the total  number of Shares
at any one





time optioned  and/or  purchased under this Plan does not exceed 388,002 Shares.
The Plan may be  abandoned  or  terminated  at any time by the Board except with
respect to any  Options  then  outstanding  under the Plan.  No Option  shall be
granted pursuant to the Plan after ten years from effective date of the Plan.

     12.  Amendment  of Plan.  The  Board  may at any time and from time to time
modify  and amend the Plan  (including  the form of any option  agreement  to be
executed  pursuant  hereto)  in any  respect:  provided,  however,  that no such
amendment  shall:  (a) increase (except in accordance with Section 6 hereof) the
maximum  number of Shares for such Options may be granted  under the Plan either
in the aggregate or to any  individual;  (b) reduce  (except in accordance  with
Section 6 hereof) the minimum option prices which may be  established  under the
Plan;  (c) extend the period or periods  during which  Options may be granted or
exercised;  (d) change the  provisions  relating to  adjustments to be made upon
changes in  capitalization.  The termination or any modification or amendment of
the Plan shall not, without the consent of the Optionee,  affect such Optionee's
rights under an Option theretofore granted to him.

     13. Applicability of Plan to Outstanding Stock Options. This Plan shall not
affect the terms and conditions of any  non-qualified  stock options  heretofore
granted to any individual by the Company (or any of its predecessors), under any
other plan or agreement  relating to non-qualified  stock options,  nor shall it
affect any of the rights of any  individual to whom such a  non-qualified  stock
option was  granted,  except to the extent in either  event that the  individual
Optionee  consents to the  application  of this Plan to his or her  options,  in
which case such options shall be considered Option granted under this Plan.

     14.  Effective Date of Plan. This Plan shall become effective upon adoption
by the Board,  subject to approval by the shareholders of the Company (or any of
its predecessors).  This Plan shall not become effective unless such shareholder
approval shall be obtained  within twelve months before or after the adoption of
the Plan by the Board.

     15. Change in Control. In the event of a "change in control of the Company,
any option granted  hereunder shall be deemed to be fully vested and immediately
exercisable,  entitling the Optionee to immediately  exercise the Option in full
and to purchase,  prior to the  effective  date of any "change in control",  the
full number of Shares  subject to such option  which he or she  otherwise  would
have been  entitled to purchase  during the remaining  term of such option.  The
Committee shall give each Optionee at least thirty (3) days prior written notice
of any event giving rise to an immediate purchase right under this Section 15.

For  purposes of this  Section 15, the phrase  "change-in-control  means (1) any
"person" (as defined in Sections 13(d) and 14 (d) of the Securities Exchange Act
of 1934 (the "Exchange Act") becoming the "beneficial owner" (as defined in Rule
13d-3 under the Exchange  Act),  directly or  indirectly,  of  securities of the
Company  representing twenty percent (20%) or more of the Company's  outstanding
securities having the right to vote at the election of directors, or (ii) during
any period of two (2)  consecutive  years, a change in the majority of the Board
of  Directors  unless the election of each new Director was approved by at least
two-thirds  of the  Directors  then  still in office  who are  Directors  at the
beginning  of such two (2) year  period ", or (iii) a merger,  consolidation  or
sale of all or  substantially  all of the  assets  of the  Company  in which the
Company is not the surviving  institution,  or (iv) the  distribution of a proxy
statement  soliciting  proxies from shareholders of the Company by someone other
than the current management of the company,  seeking  shareholder  approval of a
plan of  reorganization,  merger or





consolidation  of,  the  Company  or  similar   transaction  with  one  or  more
corporations  as  result  of  which  the  outstanding  shares  of the  class  of
securities  then  subject to the plan of  reorganization  are  exchanged  for or
converted into cash or property or securities not issued by the Company,  or (v)
a tender offer is made for twenty percent (20%) or more of the voting securities
of the Company.
