I'm not sure what's wrong with the above (have you tried each of the two nested
SpanNot clauses independently?), but here's another thing to try:
<SpanNot>
<Include>
<SpanOr>
<SpanNear slop="2147483647" inOrder="true">
<SpanTerm>t293</SpanTerm>
<SpanTerm>L_3</SpanTerm>
<SpanTerm>t4979</SpanTerm>
</SpanNear>
<SpanNear slop="2147483647" inOrder="true">
<SpanTerm>t4979</SpanTerm>
<SpanTerm>L_3</SpanTerm>
<SpanTerm>t293</SpanTerm>
</SpanNear>
<SpanOr>
<Exclude>
<SpanTerm>L_2</SpanTerm>
</Exclude>
</SpanNot>
