          Re: Registration Statement on Form S-8

     Ladies and Gentlemen:

     We have acted as counsel to Convera  Corporation.,  a Delaware  corporation
(the "Company"), in connection with the preparation and filing of a Registration
Statement on Form S-8 (the  "Registration  Statement"),  filed by the Company on
the date hereof with the Securities and Exchange Commission under the Securities
Act of 1933, as amended (the "Act"), with respect to the registration of a total
of 3,000,000  shares of common  stock of the Company,  $0.01 par value per share
(the "Shares")  reserved for issuance  under the Company's  Amended and Restated
2000 Stock Option Plan (the "Plan").  All capitalized terms used in this opinion
and not otherwise defined shall have the respective meanings ascribed to them in
the Registration Statement.

     In our  capacity as counsel and in  connection  with the  rendering  of the
opinions set forth below,  we have  examined  originals or  photostatic  copies,
certified or  otherwise  authenticated  to our  satisfaction,  of the  Company's
Amended  and  Restated  Certificate  of  Incorporation,   By-laws,  as  amended,
resolutions of the Board of Directors of the Company, the Registration Statement
and  exhibits  thereto  and the  related  prospectus,  the Plan  and such  other
documents,  instruments  and records as we deemed  necessary or appropriate  for
purposes of rendering this opinion.

     In  rendering  this  opinion,  we have  assumed  and relied  upon,  without
independent  investigation,  other than the inquiry  referred to above,  (i) the
authenticity,  completeness, truth and due authorization, execution and delivery
of all  documents  submitted to us as  originals,  (ii) the  genuineness  of all
signatures  on  all  documents  submitted  to us as  originals,  and  (iii)  the
conformity  to the  originals of all  documents  submitted to us as certified or
photostatic copies. As to certain factual matters,  we have relied,  without any
investigation,   upon  the  accuracy  of  certain  of  the  representations  and
warranties in the  certificates of certain  officers of the Company and upon the
accuracy  of the  statements  contained  in the  Registration  Statement  and in
certificates of public officials referred to above.

     The laws  covered by the opinions  expressed  herein are limited to (a) the
federal law of the United States and (b) the Delaware General Corporations Law.

     This opinion is given only with respect to laws and  regulations  presently
in  effect.  We assume no  obligation  to advise  you of any  changes  in law or
regulation  which may hereafter  occur,  whether the same are  retroactively  or
prospectively  applied, or to update or supplement this letter in any fashion to
reflect any facts or circumstances which hereafter come to our attention.

     Based upon the foregoing and our examination of such questions of law as we
have  deemed  necessary  or  appropriate  for the purpose of this  opinion,  and
assuming  that (i) the  Registration  Statement  becomes and  remains  effective
during the period when the Shares are offered,  issued and sold, (ii) the Shares
to be sold are issued in accordance with the terms of the applicable Plan, (iii)
the  Company  receives  the full  consideration  for the Shares as stated in the
applicable  Plan,  (iv) the per  share  consideration  for each  Share  includes
payment of cash or other lawful consideration at least equal to the par value of
the Company's Common Stock, and (v) all applicable  securities laws are complied
with, it is our opinion that the Shares covered by the  Registration  Statement,
when  issued and sold by the  Company,  after  payment  therefore  in the manner
provided in the applicable Plan and the Registration Statement,  will be legally
issued, fully paid and nonassessable.





     We hereby consent to the filing of this opinion letter as an exhibit to the
Registration Statement.

     This is a legal  opinion only and not a guaranty or warranty of the matters
discussed herein. It is understood that this opinion speaks as of the date given
and is limited to the laws in effect as of the date hereof and we  undertake  no
obligation to update this opinion (including,  without limitation,  by reason of
any events or circumstances,  including changes in law,  occurring) or to advise
you of any change of any matters stated herein,  whether legal or factual, after
the date hereof.  The foregoing opinion is qualified in its entirety by the fact
that we do not assume  any  responsibility  for the  accuracy,  completeness  or
fairness  of any  statement  contained  in  the  Registration  Statement  or the
prospectus.

                                                 Very truly yours,

                                                 /s/ Heller Ehrman LLP
