Agreement and Plan of Reorganization and Merger dated as of March 4, 1998 by and

                  United is a publicly owned  company,  whose stock is traded on
                  NASDAQ.

B.       Proposed Transaction Between the Parties

         Pursuant to the Agreement and in accordance  with North Carolina merger
         law,  United shall be merged with and into Triangle (the "Merger") with
         Triangle  surviving the Merger.  At this time,  the separate  corporate
         existence  of United  shall  cease  while the  corporate  existence  of
         Triangle as the surviving  corporation  shall  continue  unaffected and
         unimpaired by the Merger.

         Upon  consummation  of the Merger,  United's  business shall become and
         operate under the name "Triangle Bank" and will continue to conduct the
         business  of a North  Carolina  bank  corporation  at the then  legally
         established branches and main offices of Triangle.  The duration of the
         corporate existence of Triangle, as the surviving corporation, shall be
         perpetual and unlimited.

         The  Merger is  expected  to provide  Triangle  with  certain  business
         advantages in comparison to  Triangle's  current  structure,  including
         increased ability to expand the business and economies of scale.

         Pursuant  to  the  Agreement,  the  United  Shareholders  will  receive
         (through a designated  transfer  agent) 0.945 shares of Holding Company
         Stock for each  share of United  Stock  held  immediately  prior to the
         Effective  Time (as  defined  below)  of the  Merger.  In the event the
         exchange  of shares  results  in the  creation  of  fractional  shares,
         Holding  Company will deliver cash to the designated  transfer agent in
         an  amount  equal to the  Aggregate  Market  Value (as  defined  in the
         Agreement) of all such  fractional  shares,  which shall be remitted to
         the former United  Shareholders in lieu of their  fractional  shares in
         accordance  with their  respective  interests.  The  consideration  for
         fractional   shares  is  solely  for  the  purpose  of   avoiding   the
         inconvenience and expense of Holding Company issuing  fractional shares
         and does not represent separately bargained for consideration.

         Likewise, any warrants and options granted by United to purchase shares
         of United Stock



Mr. Michael S. Patterson               Page 3                    June 15, 1998



         will be converted into warrants and options to purchase the same number
         of shares of Holding Company Stock  multiplied by the Exchange Rate (as
         defined by the Agreement) on the same terms and conditions as currently
         in effect.

         The  "Effective  Time" of the Merger is  defined in Article I,  Section
         1.07 of the  Agreement  as the date and time  when the  Merger  becomes
         effective  as set forth in the  Articles of Merger filed with the North
         Carolina  Secretary of State in accordance with North Carolina law. The
         Articles of Merger will be filed once the  Agreement  has been approved
         by the required governmental and regulatory authorities.


Opinion
- --------

In  rendering  our  opinion,  we have  relied upon (i) the  Agreement;  (ii) the
representations  given by the parties,  which are annexed hereto; and (iii) such
other documents as we have deemed necessary or appropriate.  We have assumed the
genuiness of all  signatures,  the legal  capacity of all natural  persons,  the
authenticity  of all documents  submitted to us as originals,  the conformity to
original documents of all documents  submitted to us as certified,  conformed or
photostatic  copies,  and the  authenticity of the originals of such copies.  We
have also assumed that the Agreement reflects all the material facts relating to
Holding Company,  United, and Triangle. Our opinion is expressly conditioned on,
among other  things,  the  accuracy as of the date  hereof,  and the  continuing
accuracy,  of all such facts and representations.  If any of the representations
annexed  hereto  are  incorrect  in  whole or in  part,  or if the  terms of the
Agreement are altered before  consummation of the Merger,  such  inaccuracies or
alterations  may have a  material  effect  upon our  opinion  expressed  in this
letter.

Based upon the foregoing, and taking into consideration the statements contained
in the Section marked "Caveat" below, it is our opinion that:

         1.       The Merger will qualify as a reorganization  under Sections  
                  368(a)(1)(A) and 368(a)(2)(D) of the Code;

         2.       Except  with  respect  to any  cash  payments  to  the  United
                  Shareholders  in lieu of  fractional  shares,  no gain or loss
                  will be recognized to the United  Shareholders upon receipt of
                  Holding   Company  Stock   (including  any  fractional   share
                  interests  to which they may be  entitled)  solely in exchange
                  for shares of United Stock;

         3.       The  aggregate  federal  income tax basis of  Holding  Company
                  Stock  (including  fractional  share  interests  to which  the
                  United  Shareholders  may be entitled)  received by the United
                  Shareholders  will be the same as the aggregate federal income
                  tax  basis  of  the  United  Stock   surrendered  in  exchange
                  therefor;

         4.       The holding  period of Holding  Company Stock  received by the
                  United  Shareholders  will  include  the  period for which the
                  exchanged United Stock was held, provided the exchanged United
                  Stock was held as a capital asset by United Shareholders on 
                  the date of the exchange; and




Mr. Michael S. Patterson               Page 4                    June 15, 1998


         5.       The  payment of cash in lieu of  fractional  share  interests 
                  of Holding  Company  Stock will be treated  as if  fractional 
                  shares were  distributed  as part of the Merger in payment of 
                  and in exchange  for the United  Shareholders'  United  Stock 
                  and then  redeemed by Holding Company for cash as provided for
                  in Sections 302 or 301, depending on the attribution  rules of
                  Section 318. Assuming  a  shareholder's  stock  is a  capital 
                  asset  and  that  Section  302  applies  to the shareholder,  
                  a shareholder  receiving such cash will recognize capital gain
                  or loss equal to the difference  between  the amount of cash  
                  received  and the  shareholder's  adjusted  basis in the
                  fractional share interest.

Caveat
- ------

The  foregoing  opinion  addresses  only the five  items  set forth  herein  and
therefore,  no tax  opinion is hereby  expressed  regarding  any other  federal,
state,  local,  or other tax issues or about any other  matter not  specifically
mentioned herein.

No opinion is expressed  regarding  the tax  consequences  of the  conversion of
outstanding warrants and options to purchase common stock of United into Holding
Company  warrants  and  options.  Holders of United's  outstanding  warrants and
options  should  consult  their own tax  advisors  regarding  the  effect of the
proposed Merger.

No opinion is expressed  regarding any tax consequences  affecting  recapture of
loan loss  reserves and the related bad debt  reserves for any of the parties to
the Merger which may arise from the application of Section 585 of the Code.

Our opinion is based on the relevant  provisions of the Internal Revenue Code of
1986,   as  amended,   the   regulations   thereunder,   and  the  judicial  and
administrative  interpretations  thereof.  There  are  no  assurances  that  the
conclusions  reached herein will be accepted by the Internal  Revenue Service or
judicial authorities if challenged. Any legislative, regulatory, administrative,
or judicial decisions  subsequent to the date of this opinion may have an impact
on the validity of our conclusions.  Unless you specifically  request otherwise,
we will not update our  opinion  for  changes  to the law,  regulations,  or the
judicial and administrative interpretations thereof.

This opinion is being furnished in connection with the Registration Statement on
Form S-4 to be filed by Holding Company. We hereby consent to the filing of this
opinion as an exhibit to the  Registration  Statement.  This  opinion may not be
used or relied on for any other purpose and may not be  circulated,  quoted,  or
otherwise referred to for any other purpose without our express written consent.

                       Re:  Agreement  and Plan of  Reorganization  and  Merger
                       by and  among  United Federal Savings Bank, Triangle Bank
                       and Triangle Bancorp, Inc.

Dear Sirs:

         In connection with the proposed merger (the "Merger") of United Federal
Savings Bank ("United"), a federally-chartered savings bank with and into
Triangle Bank ("Triangle"), a North Carolina banking corporation, pursuant to
the terms of the Agreement and Plan of Reorganization and Merger dated as of
March 4, 1998 (the "Agreement") by and among United, Triangle, and Triangle
Bancorp, Inc. ("Holding Company"), a North Carolina business corporation, and
each as described in the Registration Statement on Form S-4 to be filed by
Holding Company with the Securities and Exchange Commission in June of 1998 (the
"Registration Statement"), you have rendered opinions pursuant to the
requirements of Item 21(a) of Form S-4 under the Securities Act of 1933, as
amended, and pursuant to our request.

         In connection with such opinions, and recognizing that you will rely on
this letter in rendering said opinions, the undersigned, a duly authorized
officer of the Holding Company and acting as such, hereby certifies, that, to
the best knowledge of the management of Holding Company, the facts relating to
the Merger as described in the prospectus included as part of the Registration
Statement ("Prospectus"), including attachments thereto, are true, correct and
complete in all material respects and hereby certifies, to the best knowledge of
the management of Holding Company, to the following as of the date hereof.
Insofar as such certification pertains to any person (including United or any of
its subsidiaries) other than Holding Company and any of its subsidiaries, such
certification is only as to the knowledge of the undersigned without specific
inquiry. Unless otherwise noted, all section references herein shall be to the
Internal Revenue Code of 1986, as amended (the "Code") and the regulations (the
"Regulations") thereunder.


Coopers & Lybrand L.L.P             Page 2                          June 3, 1998

1.       The Merger will be consummated in compliance with the material terms of
         the Agreement and none of the material terms and conditions therein
         have been waived or modified and Holding Company has no plan or
         intention to waive or modify any such material condition.

2.       The ratio for the conversion of shares of United stock for common stock
         of Holding Company and options of United for options of Holding Company
         in the Merger was negotiated through arm's length bargaining.
         Accordingly, the fair market value of Holding Company common stock to
         be received by United shareholders in the Merger will be approximately
         equal to the fair market value of the United stock surrendered by such
         shareholders in the conversion.

3.       Triangle will acquire at least 90 percent of the fair market value of
         United's net assets and at least 70 percent of the fair market value of
         United's gross assets held immediately prior to the Merger. For this
         purpose, amounts used to pay reorganization expenses and all
         redemptions and distributions (except for regular, normal dividends)
         made immediately prior to the Merger will be included as assets of
         United held immediately prior to the Merger.

4.       Prior to the transaction, Holding Company will be in control of
         Triangle within the meaning of Section 368(c) of the Code.

5.       Triangle will not issue additional shares of its stock following the
         transaction that would result in Holding Company losing control of
         Triangle within the meaning of Section 368(c) of the Code.
6.       There is no plan or intention by Holding Company, or any party related
         (as defined in ss.1.368-1(e)(3) of the Regulations) to Holding Company,
         to acquire United stock prior to the Merger.

7.       Holding Company is not currently negotiating with another party
         regarding the sale of Holding Company.

8.       The management of Holding Company is not aware of any person related
         (as defined in ss.1.368-1(e)(3) of the Regulations) to United having
         acquired any of the United stock in connection with the Merger.

9.       The management of Holding Company is not aware of any redemptions of
         United stock made by United in connection with the Merger.

10.      The management of Holding Company is not aware of any distributions to
         United shareholders made by United (except for regular, normal
         distributions) in connection with the Merger.



Cooper & Lybrand L.L.P                 Page 3                       June 3, 1998

11.      Except for fractional share interests, there is no plan or intention by
         Holding Company,  or any party related (as defined in  ss.1.368-1(e)(3)
         of the Regulations) to Holding  Company,  to reacquire any of its stock
         issued in the Merger.  However,  such stock could be reacquired  from a
         former United shareholder by Holding Company through stock purchases by
         Holding  Company in the open  market of Holding  Company's  widely held
         stock,  pursuant to Holding  Company's  regular stock purchase  program
         conducted for a good business purpose independent of the Merger.  Under
         this program the aggregate  amount of stock purchases will not equal or
         exceed ten percent of the outstanding stock of Holding Company. Holding
         Company knows of no intent of United shareholders to sell shares in the
         repurchase  program;  even  if  all  shares  to  be  purchased  in  the
         repurchase  program were  purchased from United  shareholders  of stock
         received  in the  Merger,  such sales  would not cause over half of the
         consideration provided by Holding Company to United shareholders in the
         Merger to be cash (including the cash received in the repurchases).

12.      Holding Company has no plan or intention to liquidate Triangle or to
         merge Triangle with and into another corporation. Additionally, Holding
         Company has no plan or intention to sell or otherwise dispose of the
         stock of Triangle; or to cause Triangle to sell or otherwise dispose of
         the assets of United acquired in the Merger, except for dispositions
         made in the ordinary course of business or transfers (or successive
         transfers) described in Section 368(a)(2)(C) of the Code.

13.      To the knowledge of Holding Company, the liabilities of United assumed
         by Triangle and the liabilities to which the transferred assets of
         United are subject were incurred by United in the ordinary course of
         its business. No liabilities of any person other than United will by
         assumed by Triangle in the Merger.

14.      Following the Merger, Triangle will, directly or through a member of
         its "qualified group" (as defined in ss.1.368-1(d)(4)(ii) of the
         Regulations),continue United's historic business or use a significant
         portion of United's historic business assets in a business.

15.      Holding Company, Triangle, United, and United shareholders will pay
         their respective expenses, if any, incurred in connection with the
         Merger.

16.      There is no intercorporate indebtedness existing between Holding
         Company and United or between United and Triangle that was issued,
         acquired, or will be settled at a discount.

17.      Neither Holding Company nor Triangle are investment companies as
         defined in Sections 368(a)(2)(F)(iii) and (iv) of the Code.

18.      To the knowledge of Holding Company, United is not under the
         jurisdiction of a court in a Title 11 or similar case within the
         meaning of Section 368(a)(3)(A) of the Code.


Cooper & Lybrand L.L.P.            Page 4                           June 3, 1998

19.      At the effective time of the Merger, the fair market value of the
         assets of United transferred to Triangle will exceed the sum of its
         liabilities assumed by Triangle (including liabilities, if any, to
         which its assets are subject).

20.      No stock of Triangle will be issued to United shareholders in the
         Merger.

21.      The payment of cash in lieu of fractional shares of Holding Company
         stock was not separately bargained for consideration and is being made
         solely for the purpose of saving Holding Company the expense and
         inconvenience of issuing fractional shares.

22.      The assumption by Triangle of the liabilities of United pursuant to the
         Merger is for a bona fide business purpose and the principal purpose of
         such assumption is not the avoidance of federal income tax on the
         transfer of assets of United to Triangle.

23.      None of the compensation received by any shareholder-employee of United
         pursuant to any employment, consulting, or similar arrangement is or
         will be separate consideration for, or allocable to, any of his/her
         shares of United. None of the shares of common stock received by any
         shareholder-employee of United pursuant to the Merger is or will be
         separate consideration for, or allocable to, any such employment,
         consulting, or similar arrangement. The compensation paid to any
         shareholder-employee of United pursuant to any such employment,
         consulting, or similar arrangement is or will be for services actually
         rendered and will be commensurate with amounts paid to third parties
         bargaining at arm's length for similar services.

24.      It is anticipated that less than one percent of United stock
         outstanding will be surrendered in lieu of fractional shares.

use in rendering your opinions and is not to be used, circulated, quoted, or
otherwise referred to for any other purpose (other than inclusion in your
opinion) without the express written consent of Holding Company. All of the
foregoing certifications are true to the best knowledge of the management of
Holding Company.


                                          Very truly yours,

                                 Merger by and among United Federal Savings
                                 Bank, Triangle Bank and Triangle Bancorp, Inc.

Dear Sirs:

     In connection with the proposed merger (the "Merger") of United Federal
Savings Bank ("United"), a federally-chartered savings bank with and into
Triangle Bank ("Triangle"), a North Carolina banking corporation, pursuant to
the terms of the Agreement and Plan of Reorganization and Merger dated as of 
March 4, 1998 (the "Agreement") by and among United, Triangle, and Triangle
Bancorp, Inc. ("Holding Company"), a North Carolina business corporation, and
each as described in the Registration Statement on Form S-4 to be filed by 
Holding Company with the Securities and Exchange COmmission in June of 1998 
(the "Registration Statement"), you have rendered opinions pursuant to the 
requirements of Item 21(a) of Form S-4 under the Securities Act of 1933,
as amended, and pursuant to our request.

     In connection with such opinions, and recognizing that you will rely on 
this letter in rendering said opinions, the undersigned, a duly authorized 
officer of United and acting as such, hereby certifies that, to the best 
knowledge of the management of United, the facts relating to the Merger as
described in the prospectus included as part of the Registration Statement
("Prospectus"), including attachments thereto, are true, correct and complete in
all material respects and hereby certifies, to the best knowledge of the 
management of United, to the following as of the date hereof. Insofar as such 
certification pertains to any person (including Holding Company or any of its 
subsidiaries) other than United and any of its subsidiaries, such certification
is only as to the knowledge of the undersigned without specific inquiry. Unless
otherwise noted, all section references herein shall be to the Internal Revenue
Code of 1986, as amended (the "Code") and the regulations (the "Regulations")
thereunder.

1.   The Merger will be consummated in compliance with the material terms of the
     Agreement and none of the material terms and conditions therein have been
     waived or modified and United has no plan or intention to waive or modify
     any such material condition.

2.   The ratio for the conversion of shares of United stock for common stock of
     Holding Company and options of United for options of Holding Company in
     the Merger was negotiated through arm's length bargaining. Accordingly,
     the fair market value of Holding Company common stock to be received by
     United shareholders in the Merger will be approximately equal to the fair
     market value of the United stock surrendered by such shareholders in the
     conversion.

3.   Triangle will acquire at least 90 percent of the fair market value of 
     United's net assets and at least 70 percent of the fair market value of
     United's gross assets held immediately prior to the Merger. For this
     purpose, amounts used to pay reorganization expenses, and all redemptions
     and distributions (except for regular, normal dividends) made immediately
     prior to the Merger will be included as assets of United held immediately
     prior to the Merger.

4.   United has not redeemed any of the United stock, has not made any 
     distribution with respect to any of the United stock (except for regular,
     normal distributions), or disposed of any of its assets in anticipation
     of or as a part of a plan for the acquisition of United by Triangle.

5.   United is not aware of any person related (defined in SS1.368-1(e)(3) of 
     the Regulations) to United having acquired any of the United stock in
     connection with the Merger.

6.   The assumption by Triangle of the liabilities of United pursuant to the
     Merger is for a bona fide business purpose and the principal purpose of 
     such assumption is not the avoidance of federal income tax on the transfer
     of assets of United to Triangle pursuant to the Merger.

7.   Holding Company, Triangle, United, and United shareholders will pay their
     respective expenses, if any, incurred in connection with the Merger.

8.   There is no intercorporate indebtedness existing between United and Holding
     Company or between United and Triangle that was issued, acquired, or will
     be settled at a discount.

9.   United is not an investment company as defined in Sections 
     368(a)(s)(F)(iii) and (iv) of the Code.

10.  United is not under the jurisdiction of a court in a Title 11 or similar
     case within the meaning of Section 368(a)(3)(A) of the Code.

11.  On the date of the Merger, the fair market value of the assets of United
     will exceed the sum of its liabilities (including liabilities, if any,
     to which its assets are subject).

12.  Any options to acquire stock in United issued by United that are to be
     converted into options to acquire Holding Company stock pursuant to the
     terms of the Merger were issued by United for bona fide business purposes.

13.  The liabilities of United assumed by Triangle and the liabilities to which
     the transferred assets of United are subject were incurred by United in the
     ordinary course of its business. No liabilities of any person other than 
     United will be assumed by Triangle in the Merger.

14.  None of the compensation received by any shareholder-employee of United 
     pursuant to any employment, consulting, or similar arrangement is or will
     be separate consideration for, or allocable to, any of his/her shares of 
     United. None of the shares of common stock received by any shareholder-
     employee of United pursuant to the Merger is or will be separate 
     consideration for, or allocable to, any such employment, consulting, or 
     similar arrangement. The compensation paid to any shareholder-employee 
     of United pursuant to any such employment, consulting, or similar
     arrangement is or will be for services actually rendered and will be
     commensurate with amounts paid to third parties bargaining at arm's 
     length for similar services.

15.  It is anticipated that less than one percent of United stock outstanding
     will be surrendered in lieu of fractional shares.

16.  The payment of cash in lieu of fractional shares of Holding Company stock
     was not separately bargaining for consideration and is being made solely
     for the purpose of saving Holding Company the expense and inconvenience
     of issuing fractional shares.

     This letter is being furnished to you solely for your benefit and for use 
in rendering your opinions and is not to be used, circulated, quoted, or 
otherwise referred to for any other purpose (other than inclusion in your 
opinion) without the express written consent of United. All of the foregoing
certifications are true to the best knowledge of the management of United.

                                           Very truly yours,

                                           /s/ John A. Barker
